Oryx & Crake Summary Essay

Xenotransplantation is the transplantation of living cells, tissues or organs from one species to another such as from pigs to humans ( Medical grafting). Such cells, tissues or organs are called xenografts or xenotransplants. The term allotransplantation refers to a same-species transplant. Human xenotransplantation offers a potential treatment for end-stage organ failure, a significant health problem in parts of the industrialized world and worldwide shortage of organs for clinical implantation. It also raises many novel medical, legal and ethical issues. A continuing concern is that pigs have different lifespans than humans and their tissues age at a different rate. Disease transmission (xenozoonosis) and permanent alteration to the genetic code of animals are a cause for concern. Genetic engineering, recombinant DNA technology, genetic modification/ manipulation (GM) and gene splicing are terms that are applied to the manipulation of genes. It involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually express a protein to reach desired effects. Cloning is the process of creating an identical copy of something. Genetic recombination is the process by which a strand of DNA is broken and then joined to the end of a different DNA molecule. A genetically modified organism (GMO) is an organism whose genetic material has been altered using the genetic engineering techniques generally known as recombinant DNA technology. Why Oryx and Crake Was Written â€Å"Every novel begins with a what if and then sets forth its axiom. The what if of Oryx and Crake is simply What if we continue down the road we’re already on? How slippery is the slope? What is our saving graces? Who’s got the will to stop us?† –Margaret Atwood Settings in Oryx and Crake Pre-Catastrophic Society: Games With Virtual Reality And Virtual Violence Society Fixated on Physical Perfection and Longevity, Virtual Elimination Of The Middle Class (produced a gap between rich and poor), Disappearance Of Safe Public Space, People Live In Either Tightly Controlled Compounds Of The Elites Or Dangerous Pleebands, Almost Everything Is For Sale, Medical Advancements, Life Is In The Hands Of Large Corporations, Private Security Forces, Scientific Advancements: Genetic Engineering & Xenotransplant, Technologically Driven, Extreme commercialization and commodification of life and the commodification of human life and sexuality in prostitution and online child pornography. Jimmy and Crake spend a lot of their free time playing online computer games such as Kwiktime Osama (a reference to Osama bin Laden) and Blood and Roses, or watching live executions, Noodie News, frog squashing, graphic surgery and child pornography. Post-Catastrophic Society: Naturalistic society Science vs. Anti-Science â€Å"Please don’t make the mistake of thinking that Oryx and Crake is anti-science. Science is a way of knowing, and a tool. Like all ways of knowing and tools, it can be turned to bad uses. And it can be bought and sold, and it often is. But it is not in itself bad. Like electricity, it’s neutral. The driving force in the world today is the human heart – that is, human emotions. (Yeats, Blake – every poet, come to think of it – has always told us that.) Our tools have become very powerful. Hate, not bombs, destroys cities. Desire, not bricks, rebuilds them.† –Margaret Atwood Plot Summary of Oryx and Crake The protagonist of Oryx and Crake is Snowman, clad only in a bed sheet and a Red Sox cap, who appears to be the last human being on Earth. He’s not entirely alone, however; strange hybrid beasts such as wolvogs, pigoons and rakunks are roaming freely. As well, a group of what he calls Crakers—strange human-like creatures—lives nearby. They bring Snowman food and consult him on matters that surpass their understanding; thus, Snowman comes across as a post-apocalyptic hermit guru. As the story develops, these assorted lifeforms are revealed to be the products of genetic engineering. In flashbacks, we learn that Snowman was once a young boy named Jimmy, who grew up in the early 21st century. His world was dominated by multinational corporations which kept their employees’ families in privileged compounds separated from a global lower moiety of pleeblands. Shortly after Jimmy’s family moved to the HelthWyzer corporate compound (where his father worked a s a genographer) Jimmy met and befriended Glenn (later known as Crake), a brilliant science student. Atwood’s satirical take on current society is presented most pointedly in the jaded activities of these two youths. Jimmy and Crake spend a lot of their free time playing online computer games such as Kwiktime Osama (a reference to Osama bin Laden) and Blood and Roses, or watching live executions, Noodie News, frog squashing, graphic surgery and child pornography. One of Glenn’s favourite pastimes is an online game called Extinctathon, a trivia game which requires immense knowledge of extinct animal and plant species. Using the codenames Thickney (Jimmy) and Crake (Glenn), they both play as teenagers. It is not until they are both in university that Jimmy discovers that Crake has worked his way up to become a Grandmaster. On another trip through the dark underbelly of the Web, they come across an Asian child pornography site, where Jimmy is struck and haunted by the eyes of a young girl. Unknown to Jimmy, Crake is similarly affected by the sig ht of this young girl. Crake eventually finds this girl (or a woman who could be her) and hires her, as both a prostitute and a teacher of the Crakers. Her name is Oryx. Jimmy identifies the haunting memory of the young girl with Oryx, though it is never made clear as to whether or not the two are the same person. Oryx eventually becomes intimately involved in the lives of Jimmy and Crake, and both fall in love with her. Oryx, however, views their relationship as strictly professional and only admires Crake as a scientist and â€Å"great man†. For fun and affection she turns to Jimmy, though her feelings for him are not as clear. The two hide their relationship from Crake, and Jimmy is often plagued with the thought of Crake finding out about his betrayal. Crake uses his prominent position at a biotech corporation to launch a project to create the Crakers. His goal is to create a peaceful society that will live harmoniously with each other and nature. These genetically engine ered humans are leaf-eating herbivores and they only have sexual intercourse during limited breeding seasons when they are polyandrous. Thus, many of the apparent conflicts in human culture are replaced with a mockery of intelligent design. At the same time, Crake creates a virulent genetic pandemic that, apparently, killed off all humans except for Jimmy. Jimmy was unknowingly vaccinated with the intention of acting as a guardian for the Crakers. Thus, Crake represents a mad scientist; he is maddened by the troubled society that he lives in. His rationale is that he is heroically saving intelligent life from an inevitably dying society. In the story’s climax, Crake’s perfected â€Å"hot bioform,† present in one of his company’s products, is activated and spreads throughout the world. When called to account for his actions by Jimmy, Crake kills Oryx by slitting her throat. In rage and panic, Jimmy shoots Crake, resulting in his being left to obsess over his vanished world and unanswered questions. Jimmy contemplates abandoning the Crakers but is constantly haunted by the voice of Oryx, and reminded of his promise to her to watch over them. Though Crake opposed and belittled human religion, Sn owman instills the Crakers with his own invented religion revolving around Crake and Oryx. Oryx becomes the guardian of the animals and Crake the creator god. Crake suffers from unremembered night terrors. During visits, Jimmy hears Crake screaming in his sleep. Crake claims to not remember them. This forms one of the book’s most profound ironies. Crake is a leader in the most advanced (and corrupt) health care system in human history, and Jimmy is unable to save humanity by simply getting Crake’s head examined. At the same time, however, Crake attends a university referred to as Asperger’s U, referring to the university’s high population of incredibly intelligent, socially awkward people, which might suggest that his idea was not the product of insanity or something ‘wrong’ with him, but rather the knowledge that everything else around him was wrong. During Snowman’s journey to scavenge supplies, he is uncomfortable wearing shoes now that his feet have become toughened without them. He cuts his foot on a tiny sliver of glass. Infected by who-knows-what descendant of transgenic experiments, his body cannot fight back, and his leg becomes inflamed.Returning to the Crakers, he learns that three ragged true humans have camped nearby. He follows the smoke from the fire and watches as they cook a rakunk. Uncertain of how he should approach them (Blast them to bits to protect the Crakers? Approach with open arms?) he checks his now unworking watch and thinks, â€Å"Time to go,† leaving the reader to speculate as to what his actions and future will be. Literay Works Coral Ann Howells argues that Oryx and Crake is in some ways a sequel to Atwood’s The Handmaid’s Tale in that it carries the national catastrophe in the earlier novel to global level[5]. A major reference seems to be to the â€Å"Last Man† topos in science fiction, which was inaugurated by Mary Shelley’s The Last Man, also a post-apocalyptic novel, whose main character is the only survivor of a plague that has killed off all other humans. George Orwell’s Nineteen Eighty-Four (1949) had a working title that relates it to Shelley’s book: â€Å"The Last Man in Europe†[6]. Other references, of course, include Shelley’s Frankenstein (1818/1831) as well as Jonathan Swift’s Gulliver’s Travels[7] (1626/1635). Gulliver’s Travels is also the source of one of the two epigraphs and puts emphasis on the claim that the speculation about the near future in Oryx and Crake serves to make a point about the present state of the world. Swift’s speaker as quoted by Atwood says: â€Å"my principal design was to inform you, and not to amuse you† (Oryx and Crake, Epigraph). The second quotation from Virginia Woolf’s To the Lighthouse (1927) refers to the absence of safety in the word, pointing to Snowman’s existence in the world af ter Crake’s catastrophe.

Lupus Research Paper Example | Topics and Well Written Essays - 1250 words

Lupus - Research Paper Example The immune system of a person suffering from lupus cannot differentiate between normal body tissues and antigens. As a result of this, the immune system directs antibodies to normal tissues thinking that they are foreign materials. Due to this, there is swelling and pain felt by the person suffering from this disease. With advanced medical technology, different types of lupus have been identified by doctors. However the most common one is SLE or systemic lupus erythematosus. There are also others known as discoid, neonatal and drug-induced. Symptoms It is important to note that lupus is very variable. That is it is common for one to have the disease and not experience all the symptoms that other people feel. At the same time, every patient has their own feelings meaning that there are rare occasions when two or more patients experience similar symptoms. Severity also varies in individuals. Some patients experience symptoms that are severe and might last for a long time while others e xperience symptoms that are less severe and last for a few minutes but keep reoccurring. Sometimes, the patients expect to experience the severe pains that most textbooks describe but that never occurs. Some of the initial symptoms include (Basingtoke, 2011): 1. Lethargy, fatigue and weakness 2. Rashes in the skin. However, this occurs in very few cases. One in every five. 3. Swelling and pain of the join. This is experienced by almost half of the patients. Meaning that it is a very common symptom for patients with the lupus disease. 4. Fever; almost every patient experience this and it keeps occurring Diagnosis Since the symptoms of this disease vary, diagnosis of the disease is very difficult. The symptoms keep changing and in some cases, they become similar to symptoms of other diseases. For one to be confirmed as having this disease, several tests have to be performed. Urine and blood tests are however compulsory. The patient also has to be given a physical examination to know h ow fit they are. The laboratory tests include; 1. Complete blood count. This is the most common test for the disease. The number of white blood cells, platelets and red blood cells are counted and their ratio known. The results have to be analyzed properly since anemia also has almost similar results from the same test. 2. Sedimentation of erythrocytes rate. In this test, blood sample is taken and kept in a test tube from where the rate at which the red blood cells settle at the bottom of the test tube is measured. This test is very crucial since it determines the type of disease that one has. 3. Urinalysis. This is where the urine of the patient is analyzed to check the amount of proteins and red blood cells in the urine. Treatment Just like the difference in symptoms, the treatment of lupus is also different. Before administering any treatment, the doctor or physician has to analyze the signs and symptoms of the disease that the patient has shown and detriment the correct procedur e to use for treatment. As the signs keep changing, the nurse has to ensure that the patient changes the medication that they are using. This means that the nurse has to be able to closely monitor the changes that the patient is undergoing through and report this to the doctor who should change medication if necessary. Some of the treatments available include; 1. NSAIDs (Nonsteroidal anti-inflammatory drugs). This kind of medication is available over the counter. Some

Criminal Essay Example | Topics and Well Written Essays - 250 words - 1

Criminal - Essay Example According to Pell v. Procunier(1974), it was held that inmates could not have personal or face-to-face interviews with media personnel (Pollock, 2011). This prohibition is irrespective of whether the interview is peaceful and without threats. Inmates are thus advised to use other alternative methods of communication other than personal interviews. In Procunier v. Martinez, communication with inmates is highly prohibited and prison wardens have an obligation to ensure that this constitutional law is followed. In most prisons, there are prisoners who have been assigned the duty to ensure that law of prison is followed and who also speaks on behalf of prisoners. The warden in this case, has no other option but to make it known to the prisoners that the law does not allow personal interviews with the media personnel. The warden should also agree with the inmates’ clerks to maintain order in the prison. Part 2; Several inmates confined to a disciplinary segregation unit submit letters to the Warden of a correctional facility, indicating that they want to attend mandatory religious services, on a significant holy day of their chosen religion; do you have to allow them to attend? If not, why? According to May v. Sheahan, an inmate is entitled to exercise freely his religious practices as outlined in the Free Exercise Clause (Pollock, 2011). Prison regulation that does not adhere to this clause can only be upheld if it is reasonable under legitimate interests. Thus, all prisoners including those in the disciplinary unit have the right to exercise their faith. These rights should be protected as they help in the transformation process. Religion contributes a lot in strengthening their morals and in changing their criminal lifestyle to that of a morally upright person who has the ability to make ethical decisions. In relation to this, prison warden should allow the inmates to practice their faith freely and to access religious materials concerning their

Leadership and Strategic Management Essay Example | Topics and Well Written Essays - 1250 words

Leadership and Strategic Management - Essay Example Organized management and actions have existed for centauries. Management has undergone, in the past several years more so in the last centaury, methodical investigation, acceptance as a formal discipline of study and attained a common body of knowledge (Robbins & Coulter, 2005). Among the early contributors to contemporary management practices are Henry Fayol and Max Weber who are credited for developing general administrative theories. Their works centered on managers’ roles and what comprised good management practice (Robbins & Coulter, 2005). Current concepts about a managers’ role have evolved from Henry Fayol’s fourteen principals of management. Max Weber’s bureaucracy model was aimed at removing inefficiencies, patronage and ambiguity that characterized most businesses. Most components of his bureaucracy model are still inherent in big organizations to date. The universal point of ideas offered by Fayol, Weber and Taylor were majored on increased eff iciency. Thus the application of scientific management principles resulted in increased productivity of managers and the organizations as a whole (Jones & George, 2011). Leadership has been proven to have a direct cause and effect connection on organizations and their eventual success. Thus leaders have been tasked with shaping organizational strategies including its execution and efficiency (Northouse, 2007). Leaders therefore determine the culture, values, employee motivation and change tolerance within their institutions. With the on set of financial crisis, businesses have attracted keen analysis from shareholders and the general public. This has reinforced the concept of strategic management and a review of current leadership styles. Strategic management, popularized in the 1980s, is a term that covers business-wide strategy formulation, implementation and evaluation (Sadler, 2003). This usually is dependent on the leadership of an enterprise. The concept of strategic management has become important to the success or failure of enterprises, more so now that business environment require quick analysis, monitoring and precise interpretations of th eir surroundings. Though, it must be noted that not all enterprises that embrace this concept are safe from failures. One of the major reasons for failures in strategic management is poor direction from management and poor planning that strategic management is widely believed to have evolved from (Sadler, 2003). While implementing strategic management, leaders will usually be faced with the problem of change management. Change management is the planned approach to transitioning organizations from present state to a desired future state (Jones & George, 2011). Its aim is to help employees embrace and accept change in their present business environment. There are a number of beneficial reasons why an organization leadership will want to adopt change management. These include; increasing efficiency, increasing cohesiveness among employees so as to deliver objectives in a strong team, and also helps to gain a good understanding of what type of change is impending. This will usually help in smooth change transition more so touching on

Country Risk Case Study Example | Topics and Well Written Essays - 1250 words

Country Risk - Case Study Example Currently, the company fails to reach an agreement with the Hong Kong government to fund a much-needed 301 acres of expansion and started to give employees the sack. HKDLD has been losing profits that leads to the present state of being. All creative and design works are halted leaving a "shell" of 10 member team after the stripping off the "imaginers" (Business Week, 2009). Walt Disney Company (WDC) may just walk away from the negotiation from the government to focus on the upcoming Disney Shanghai. Yet Disneyland is significantly a landmark and tourist attraction, the HK government can find no comfort zone in abandoning it or funding the business. The strategy is only to keep on improving it as a competitive edge over Disney Shanghai scheduled to open in 2014. This implies the need of constant influx of taxpayers' fund for HKDLD expansion to keep the economy on the road to recovery, even though the present spending hurts the country's expenditure with HKDLD's profit book in the red expectedly (NPR, 2009). The nature of the existence of the risks of this Private-Public Partnership (PPP) project occurs due to the complexity and uncertainty of the interaction of factors that includes financing, taxation, technical details, market conditions and changes over the duration of the project (Yin Shen, Platten, 2009). Hence for the HKDLD project, the risks affecting the project expansion are identified with their preventive measures. To achieve the value for money in PPP projects, risk are allocated between this pair of private and public sectors in partnership. The risks should be allocated accordingly with respect to the type of risk and the ability of either sector to mitigate them. Based on this principle the risks are outlined alongside the preventive measures by means of allocations of identified risks. During the start of the expansion, site acquisition risk is present in land acquisition and or during retaining or demolishing existing buildings. The HK government is responsible for ens uring the acquisition of the HKDLD site and protecting the site from any intrusion and all land uses in surrounding areas. The operational private partner is responsible for the operational process of site protection or demolition of existing buildings or facilities. In all construction, the risk associate with adverse underground conditions is taken care of by the private partner since they are in charge of site survey particularly on the underground conditions that deals with the stability of foundation and supply of utilities. Polluted land and surroundings is a risk borne by both sides by the right legal disposal of construction waste and enforcement of good house keeping. Land reclamation runs the risk of delay of construction and is allocated to the private partner for adhering to the project deadline Volatility of market changes is always present with factors such as the

ESSAY - Research Paper Example The age of Callisto is around 4.5 billion years, the same as that of the planet where it is located which is Jupiter. Callisto is the furthest of the Galilean moons since it orbits from Jupiter at around 1,168,000 miles. Due to this distance from Jupiter, it takes seven days of earth to make a single complete orbit around the planet. Its orbit outside Jupiter’s main radiation strap makes the moon experience less tidal influences as compared to other Jovian moons. The size Callisto is about 3,000 miles in diameter, which is 4,800 kilometers. It is approximately the same size as planet mercury making it the third largest moon of the solar system. Callisto has the lowest density. Callisto’s mean surface temperature is 218.47 Fahrenheit (Zimmermann). Callisto was discovered by Galileo Galilei on January, 7 1610. Of all the Jupiter’s moons, it was the fourth to be discovered. It was discovered along with other three Jovian moons and it was the first for a moon to be found circling a planet which is not Earth. Galileo’s discovery finally led to the knowledge that planets orbit the sun (Zimmermann). Jupiter and its moons have been visited by several spacecraft. In 1973, Pioneer 10 arrived and by 1974, pioneer 11 had followed. During their flybys, Voyager 1 as well as Voyager 2 brought back outstanding photos. Detailed images were later to be formed by the Galileo spacecraft that travelled as near to the ground as 162 miles which is 261 kilometers over the exterior of the Galilean moons. Craters are the most noticeable feature of Callisto. This is because of the entire solar system Callisto has the most craters. According to scientist’s approximation, of the entire solar system, Callisto has the eldest surface. This moon has glimmered keen scientific interest since in 4 billion years, there is no sign of change on its geologic landscape. With no impact change on the

Importance of Information Management Essay Example | Topics and Well Written Essays - 1000 words

Importance of Information Management - Essay Example This is important in that it would assist the management plan on better ways of servicing its client. This supports the arguments form the paper that states that information management forms the basis for improving the students’ satisfaction and learning experience. Information is the only way through which management or the administration can interact with the students. I also realized that a channel linking the academic staff and the teaching staff or the teacher and the student is very important. Consequently, there must be a channel that should link them. It is clear that information presented in the paper support the claims made by Erlanger (2005)that states that knowledge management or information management impacts on innovation and organizational performance directly and indirectly (through an increase on innovation capability). This is because the acquisition of the right information from the clients, for this case, students would enable the management or the school a dministration to plan for the best strategies to adopt towards improving the performance of the students (Levy, 2003). Information management provides the basis for improving the performance of the employees. Based on the discussion from the paper, it is clear that in school setting, the performance of the teachers can be enhanced through course unit evaluation. Course unit evaluation is where the students fill a form that targets at exploring whether the teacher or the tutor is doing as expected. The paper reveals that although the course unit evaluation is important, most people especially the students take it lightly and hence fail delivering comprehensive information to the academic staff. This would prevent the staff from coming up with appropriate intervention measures. The paper affirms that it is possible to resolve this by imposing a forceful feedback into the system. This would make the student take the issue seriously. The time for evaluation is also very important. It is undisputable that if the evaluation is done at the end of the course, then the respondent, or rather the students may not benefit because the kind of changes that would be adopted would be possibly implemented in the next session. Because of this, it is true that appropriate and effective evaluation should be carried out in the middle of the course (Babcock, 2004). Appropriate and effective information management provides the basis for improving the performance of the client. Grading, for example, is an example in which this point becomes relevant. It is clear that grading is a means through which the management can meet the students’ needs. Just as the paper puts it, it is true that appropriate grading system should be able to motivate the student and not just to give them grade. The paper affirms that comments are imperative because it offers detailed, personalized feedback that would help in measuring progress towards strategic targets (Kanyengo, 2009). Additionally, the paper gives an insight of significance of using the online quizzes and homework tasks on blackboard. I wholly support this fact because adoption of online quizzes and homework task on blackboard would be time-consuming and also it allows provision of grade or a few generic statements of feedback. A study that was done by Liu & Cavanaugh (2011) reveals that teacher’s comments and feedback on the student’s assignments as well as teacher-student interaction are very

Does Thatcherism mark a radical break in British Politics Essay

Does Thatcherism mark a radical break in British Politics - Essay Example The political system implemented a number of social and economic reforms that stabilized the British society on the pillars of constant economic growth and peaceful coexistence of the citizens. The political ideologies fostered by Thatcherism fostered a classical liberalism comparable to the Rogernomics in the United States of America, in New Zealand and the economic rationalism in Australia. The system promoted reduction in the inflation rates and a free market implemented via a tight control of the supply of money into the market. These economic policies resulted in extensive privatization of some of the previous government institutions to give the citizens more control of the economy; it also led to extensive labor reforms (Johnson, 1988). The labor reforms made working conditions better for most of the civil service, and the expansion of the private sector increased the sector’s ability to offer more employment to the population. All these efforts contributed to the develo pment of a strong economy that was the dream of Margret Thatcher and, as research shows, other leaders that had come before her. Butler, Adonis & Travers, (1994) explain that Thatcherism as a system of politics introduced a unique system of governance that the previous regimes had not thought of before. After assuming office in 1979, Thatcher understood why numerous critics had previously referred the country to as ungovernable. Thatcher, on the contrary, sought to stamp her authority as the leader of the most famous political party and as the leader of the government. In most occasions, she bypassed a number of preexisting structures of governance such as parliamentary and cabinet commissions and portrayed a more personal leader of the government especially during crises. This form of administration proved fundamental in times of crises, Thatcher stamped her authority during the Falkland wars and the IRA bombs both in which she took over the management of the military and brought s anity and order once again (Adeney & Lloyd, 1988). With the wide success of the more personal form of administration, Thatcher managed to build a more prosperous society free from terror attacks despite the strong economic growth. The military expanded and developed more loyalty to the leader of the government. The country had previously yearned for this type of governance, and she developed a stable economy, the one in which law, order reigned, and the populace portrayed more spirit of patriotism towards their nation. Thatcher thus tried and tested the new form of governance and passed the mantle to other preceding regimes. To this day and through the elaborative form of David Cameron’s regime, it is evident that the prime minister is more involved with the populace and stamps his authority in the formulation and implementation of policies. Margret Thatcher made official the political system, but prior to her, a number of other political leaders had tried to introduce the ra dical economic reforms and give more economic power to the common person. The decades before Thatcherism, the country had a less favored system of politics referred to as the Buttskellite consensus. This was a purely capitalist system of leadership that made a few influential persons extremely wealthy while the rest of the population was left in abject poverty. Capitalist system of

Practical Limits to a Skyscraper Case Study Example | Topics and Well Written Essays - 500 words

Practical Limits to a Skyscraper - Case Study Example Steel can support structures of height about 6.2 miles or even more than that, whereas advanced composite steel has the tendency to support as much as 62 miles tall skyscrapers (Anissimov). Skyscrapers (layoutsparks.com). Therefore, limiting the strength of the structural materials is not the cardinal factors that may impose limits on the height of a skyscraper. There are several other factors that dictate the constructors the height of a skyscraper. There is no doubt in the fact that a skyscraper is mostly empty because it is supposed to provide room for the inhabitants. Therefore, the weight of a skyscraper is often quite less than what its massive appearance may cause the analyzer to estimate. Three factors that primarily limit the height of a skyscraper are budget, elevators, and the wind. As we go higher, the speed of wind increases and ultimately becomes dangerous for the safety and sustainability of the skyscraper. It has been found that with calm weather conditions in a tempe rate region, the speed of wind at heights of 2 km, 4 km, 6 km, 8 km, 10 km, and 12 km is 22 mph, 56 mph, 90 mph, 134 mph, 179 mph, and 200 mph respectively (Anissimov). This clearly indicates that as the skyscrapers become taller, they have to withstand greater wind pressure. Skyscrapers frequently make use of glass for improving the look.

GGSB admissions board

GGSB admissions board What would you like the GGSB admissions board to know about your professional work and / or academic experience? I think one of the best qualities which I posses is my dedication towards work. It is this quality which has helped me achieve my dreams and progress successfully in my career. I am an Engineering graduate specialized in the field of Information Technology possessing high technical and analytical skills. Apart from the regular studies I showed greater interest in understanding the application of technology in the real world. Motivated by my lecturers I presented papers with innovative ideas which were highly appreciated. One of the most outstanding works was the Simulation of Cellular Network which was presented in various Institutions in the state and earned many awards. It is now being used by my Institution in the classes to demonstrate basic functioning of cellular networks for better understanding. The final year project was the most challenging work I encountered in my academic life. I had chosen to apply my knowledge of IT in the field of Biotechnology. Being an abecedarian in this field I initially struggled to improve my understanding of the application. Leading a team of three the responsibility of success of the project weighed more on me. Together we spent all days and many sleepless nights to bring out a working model of a concept which was only paperwork. This work was taken further and later presented by my project guide in an international conference in Hong Kong. Soon after my graduation I stepped into the next phase in my career joining as a fresher with LT Infotech. During the initial days I had the opportunity to observe what a real professionals work is. In no time I became a part of this world interacting with clients all around the globe and providing back end support. Responsibilities increased with time and now I single handedly support the back end system of a global reporting application. My most substantial accomplishment has been the implementation of an online system in the backend for testing purpose. The experience I gained through these many years made me guide the entire team technically, also helping in bridging the their gap between functionality of the system and its technical implementation. Due to the short span of time allocated for this project I had to be pro-active, take lead in motivating people and completing the task. This testing tool was shared with the clients and was highly appreciated. Why are you interested in our particular program, and how do you see it helping you to reach your future goals? The world is full of opportunities, comprising of a vast array of sectors, each having its own global implications. Many industries now being driven by Technology, reaches unbelievable heights within a short span of time through its efficient management. The need of the day is to be in pace with the change and evolution of technology. By this not only can one provide solution to real-time problems but also present the most effective ones. Working with an IT firm has opened up a fascinating world of science and technology to me. It has been more than a dream to understand the nuances of this field and to expand my horizons. I want to learn more about the industry and look at the business and its technology from a much broader realm rather than from the individual components for which I have been responsible. I would consider it my professional achievement to be placed high up in the corporate ladder, and be involved in the decision making and planning of the organization. I strongly feel that technology and management are two sides of the coin which in unison form the foundation of an organization. But the application of innovative technology and making it successful requires an in depth understanding of business and the risks involved. These are some of the nuts and bolts that I require when I foresee myself in a position making strategic business decisions. A proper amalgamation of technology and management plays the key role here. While possessing a strong technical background, I feel a management degree will help me sharpen my skills and provide me an opportunity to excel in both the fields. This will also provide me a window to new ideas from different perspectives. As I go higher up in my profession, I will have the responsibility of building strong teams, making critical decisions, communicating with distinct customers from different backgrounds and coordinating with other team members to work towards a common goal. I am confident that my creative, strategic and analytical abilities will aid me in becoming an able manager. For this, I look forward to graduate with a MBA degree from a top-class college so that I can enter the corporate world fully equipped with all diverse skills that will aid me in facing the complex business environment. GGSB One of the revolutionary institutes with world-class infrastructure, highly experienced faculty and research base has been my first choice. The Management of Technology being one of the pillars of Grenoble Ecole de Managements development and its international level recognition appeals to my professional interests. I am eager to interact with a diverse and lively peer group. I feel that the learning, which comes from a competitive, dynamic and fulfilling atmosphere, will enable me to take up challenging roles in the field of management. I hope the excellent facilities and exposure at GGSB will help me out in realizing my dreams. What did you experience when you first went abroad or visited a different culture than your own? How did you overcome the cultural differences? If you have never been abroad, what would you say to a foreigner moving to your home country? India is a land where diversity varies from state to state. India is only 1/3rd the size of USA with three times the latters population. Though there are 14 different major languages spoken across various states, India has one of the largest English speaking population in the world. India is the largest democracy in the world and it fiercely protects freedom of speech, press, legal rights, religious rights, minority rights and human rights. The civilization in India is the longest surviving, which dates back to 3300 B.C. The culture and civilization has been gradually shaped over time by many great thinkers. In Indian thinking there are no absolutes, in the sense that there is a cyclic order in everything and finite and infinite, dark and light, matter and energy, beginning and end, and so on, co-exist .There is an uncanny similarity between this way of thinking and the findings of modern science. There is a marked difference between India and countries in the West when it comes to the sense of privacy. People would drop in at any time without giving any notice whatsoever and would be welcomed and served sweets or a meal and even an invitation to stay overnight in some instances. People in India almost intuitively live within their means. Even the very poor tend to save for hard times. Houses almost never use heating or air-conditioning and are made bricks or earth. The notion that if a person earns $ 2 a day is miserable is not quite true. His or her purchasing power for lifes essentials or simple needs are like $ 80, since a $ is the equivalent of Rs. 40. So, the vast majority of people in India pursue life, liberty and happiness and hence rather successfully.

Literature Review On Soil Erosion

Literature Review On Soil Erosion The Latin word erodere, (meaning to gnaw away) is the origin of the word erosion (Roose, 1996). Soil Erosion is the physical removal of topsoil by various agents, including falling raindrops, water flowing over the soil profile and gravitational pull (Lal 1990). The Soil Science Society of America defines erosion as the wearing away of the land surface by running water, wind, ice or other geological agents, including such processes as gravitational creep (SCSA, 1982). Physical erosion involves the detachment and transportation of insoluble soil particles (sand, silt and organic matter). Removal of soluble material as dissolved substances is called chemical erosion and this maybe caused by surface runoff or subsurface flow where the water moves from one layer to another within the soil profile (Lal 1990). According to ASCE, 1975, the physical processes in soil erosion include detachment of soil particles, their transportation and subsequent deposition of soil sediments downslope by raindrop impact and runoff over the soil surface. Rainfall is the most important detaching agent (Morgan and Davidson 1986; Lal, 1990) followed by overland flow in entraining soil particles (Lal 1990). The process of soil erosion occurs in three main steps, detachment of soil particles, transportation and deposition of soil particles downslope by raindrop impact and runoff over the soil surface (ASCE 1975; Morgan and Davidson, 1986, Lal 1990) followed by overland flow in entraining soil particles (Lal, 1990). Soil erosion reduces soil productivity by physical loss of topsoil, reduction in rooting depth and loss of water. In contrast soil, soil depletion means loss or decline of soil fertility due to crop removal or removal of nutrients by eluviations from water passing through the soil profile (Lal, 1990). Sedimentation however, causes off site effects like degradation of basins, accumulation of silts in water reservoirs and burial of low-lying productive areas and other problems (Lal, 1990). Sediments is the main cause of pollution and eutrophication (Lal, 1990). According to Lal 1990, soil degradation may be caused by accelerated soil erosion, depletion through intensive land use , deterioration in soil structure, changes in soil pH, leaching, salt accumulation, build up of toxic elelments such as aluminum or zinc, excessive inundation leading to reduced soil conditions and poor aeration. Soil Erosion is the most serious and least reversible form of land degradation (Lal, 1977; El-Swaify, Dangler and Amstrong, 1982). Soil erosion and soil loss , according to Lal (1990) have adverse effects on agriculture because they deplete the soils productivity and diminish the resourse base. 2.2 Soil Erosion Process Geologic erosion can be caused by a number of natural agents including rainfall, flowing water and ice, wind and the the mass movement of soil bodies under the action of gravity which cause the loosened or dissolved earthy and rock materials to be removed from a place and eventually deposited to a new location (Lal,1990; Morgan and Davidson, 1986). The Soil Science Society of America (SCSA, 1982) described geologic erosion as the normal or natural erosion caused by geologic processes acting over long periods and resulting in the wearing away of mountains, the building up of flood plains, coastal plains. Etc. The slow and constructive natural soil erosion process has been significantly accelerated by human activities of poor farming practices, overgrazing, ground clearing for construction, logging and mining (Lo, 1990). Accelerated erosion not only affects the soil but also the environment and is the primary cause of soil degradation (Lal, 1990). Agriculture has been identified as th e primary cause of accelerated soil erosion (Pimentel, 1976). 2.3 Soil Characteristics in the Tropics Extremes of climate and wide variety of parent materials cause great contrast of soil properties in the tropics from soils in other temperate regions. In the tropics soils are highly variable and diverse like the vegetation (Sanchez and Buoi, 1975; Van Wambeke, 1992). The main soil types are alfisols, oxisols, ultisols and inceptisols (El-Swaify, 1990). Tropical soils low in weatherable minerals and basic cations (sodium, calcium, magnesium, and potassium) resulted from continuous weathering of parent materials (Lo, 1990). The ability of these soils to keep plant nutrients is largely dependent on the humus content found in plant biomass and the organic matter (Rose,1993). The inactivity of soil mineral constituents (kaolin and sesquioxides) in these soils, causes deficiency in crop nutrients, lowers the capacity to retain basic cations, limits active relationship with organic matter and excessively immobilizes phosphates and related anions, a condition which are highly toxic to plant roots (Lo, 1990). Crop production in tropical soils are constrained by primarily aluminum- derived soil acidity and infertility but generally their physical properties are favourable (El-Swaify, 1990). Tropic soils have moderate to high permeability under natural conditions, but susceptible to slaking and development of impermeable crust upon action of raindrops and as a result runoff increases with continuous cultivation (Lal, 1982). This crusting cause insignificant reduction of filtration rate, increasing water runoff which leads to acceleration of soil erosion (Falayl and Lal, 1979). It is important to note however that heavy and intense rains cause severe erosion in the tropics (Morgan, 1974; Wilkinson 1975; Amezquita and Forsythe, 1975; Lal 1976; Aina, Lal and Taylor, 1977; Bois, 1978; Sheng 1982). 2.4 Soil Erosion on Steep Slope According to Lal 1990, Steeplands refer to lands with a slope gradient greater than 20%. It is important to note however that flat undulating lands have a great potential for crop production and agricultural development. Due to the possibility of soil erosion and the problem of mechanization, the steep areas are considered marginal for agriculture production (Lal, 1990). The difficult topography in steepland agriculture restricts mechanizations of operations thus, reducing all agricultural activities (land preparation, cultivation and harvesting), limiting the farmer in scale and efficiency. Inputs such as fertilizer and pesticides have to be carried manually by the farmer. As a resulted they are used scarcely. Observably any increase in the use of these agricultural inputs will result in decline in he farmers profits from the generally lower agricultural field (Benvenuti, 1988). For all these reasons steepland farmers tend to concentrate in high value crop production of limited scale (Ahmad, 1987; Ahmad 1990). It is important to note however that farmers prefer steepslopes due to cultural hand cultivation, planting and harvesting can be done in an upright fashion (Williams and Walter, 1988). Futher more subsistence farmers are found on steep slopes because of more favourable environmental conditions such as lower temperatures, reduced diseases and h igher reliability of rainfall. (Hurni, 1988). In the tropics, removal of forest vegetation causes excessive leaching and accelerated soil nutrient loss. Being highly weathered soil types , their contained minerals generally have poor ability to retain sorbed nutrients against leaching. Clay soils with high residualmiron contents are considered superior in resistance to runoff caused soil erosion; thus, soils emanated from basic igneous rocks and red soils developed from calcareous rocks are strongly aggregated due to the cementing property of iron oxides, hence, soil erosion is expected to be less than for most other soils. Also soils developed from fragmentary volcanic materials with andic properties are resistant to soil erosion (Sheng, 1986; Ahmad, 1987; Ahmad, 1990; Lal, 1990). Soils formed from shales, schists, phyillites and sandstones are considered highly erodible. Soils produced from these rocks are high in both sand or silt fraction, and clay minerals and iron oxides are generally insufficient as cementing agents for a stable-structured soil. These parent materials are generally rich in muscovite occurring in all soil particle-size fractions. Micah-rich soils are weak-structured, and thus raindrops can easily dislodged the weak aggregates, while the clay fraction dispersed in water. The resulting mica flakes settling on their flat axes in the water film on the soil surface causes soil crusting. The formation of soil crusts further restricts water entry into the soil (Ahmad and Robin, 1971; Sumner, 1995), resulting to disposal of a much greater volume of runoff water, a condition which leads to further disintegration of soil aggregates and transport of colloidal soil material (Ahmad, 1987; Ahmad 1990). Soil crust restricts gaseous exchange leading to anaerobic soil conditions, denitrification, toxic effects due to ethylene production, and mechanical impedance to seedling emergence (Ahmad 1987; Ahmad, 1990). Steep slope cultivation can cause certain instability in the ecological system with both onsite and offsite detrimental impacts (El-Swaify, Garnier and Lo, 1987). Soil, climate, land use and farming systems affect the extent and the degree of severity of soil erosion. However, regardless of soil and climatic conditions, intensively used steeplands in densely populated regions experience severe soil erosion problem. Land use influences the degree of severity of soil erosion on steeplands. Uncontrollable grazing or over grazing, exensive and abusive cultivation, diversified cropping are responsible for severe soil erosion in unprotected arable lands (Roose, 1988; Liao et al 1988). Ahmad (1987;1990) reportd soil loss of approximately 120 t0 180 tonnes per hectare in Tobago Trinidad. In Australia, annual soil loss of 200 t/ha to 328 t/ha has ben reported from sloping sugar cane plantations in central and north Queensland (Sallaway, 1979; Mathews and Makepeace 1981). There are two types of soil erosion associated with the Caribbean region, land slipping and gullying. Land slipping is a manifestation of mass movement associated with steepland agriculture and the severity being strongly influenced by the parent materials. Land clearing (example deforestation) and crop production can influence land slipping particularly in the early portion of the wet season when the cleared soil wets faster due to saturation of the soil above rock. Serious dislocations, crop loss and destruction of any mechanical anti erosion devices can result from this form of mass movements. Due to drastic changes in hydrological conditions experienced by land naturally prone already to slipping and cleared for agriculture for the first time land slippage would be of common experience (Ahmad 1987; Ahmad 1990). Gullying is another common form of soil erosion that occurs on steep land bcause of the terrain involved. This is more common on sandy soils, volcanic soils and vertisols, which are all porous materials. Soils easily attain saturated conditions upon the rapid entry of water, consequently breaking the material and ultimately, leading to the formation of gullies. Agricultural activities enables this soil erosion in steeplands by allowing rapid soil wetting upon the start of the wet season. Farming activities though unsuitably oriented field boundaries, foot tracks and the lack of provision for disposal of surface water are some main causes of gullying, even on soils not prone to this tpe of steepland soil erosion (Ahmad 1987;Ahmad 1990). Since steeplands are traditionally considered marginal for agricultural crop production, most research on soil erosion and soil conservation has been done on either flat land or rolling land with a maximum slope of about 20%'(Lal, 1988). 2.5 Factors Affecting Soil Erosion The causes of soil erosion have been intensively discussed during the past 40 years. Soil erosion is a natural process that is enhanced by human activity (Richter, 1998) and occurs in all landscapes and under different land uses. In addition to human activities, soil erosion processes are also caused by morphometric characteristics of the land surface, the erosive forces of rainfall and the erodibility of soils and soil surfaces. When rainwater reaches the soil surface it will either enter the soil or run off. Runoff occurs when the rainfall intensity exceeds the infiltration capacity of the soil. Water erosion is the result of the dispersion action of rain drops, the transporting power of water and also the vulnerability of the soil to dispersion and movement (Baver and Gardner, 1972). The effects of soil erosion is also classified: definition of gullies and explanation of gully development is given by Morgan (1996), as well as Hudson (1995) who additionally focuses on individual cases of the development of gullies. Toy et al (2002) give detailed definitions of soil erosion features and processes such as sheet erosion and inter-rill erosion, rill erosion, as well as ephemeral and permanent gully erosion. Rill erodibility depends both directly and indirectly on soil properties such as bulk density, organic carbon and clay content, clay mineralogy, cations in the exchange complex, soil pH and experimental conditions such as moisture content, aging of prewetted soil and quality of eroding water (Rapp,1998). Govers (1990) found that runoff erosion resisitance of a loamy material was extremely sensitive to variation in the initial moisture content and to a lesser extent to changes in bulk density. The process of water erosion can be separated into two components, rill and interrill erosion (Young and Onstad, 1978). Interrill erosion (sheet erosion) is mainly caused by raindrop impact and removes soil in a thin almost imperceptible layer (Foster, 1989). In interril erosion the flow of water is generally unconfined, except between soil clods and covers much of the soil surface. As the velocity of flow increases the water incises into the soil and rills forms (Evans,1980). Rill erosion begins when the eroding capacity of the flow at some point exceeds the ability of the soil particles to resistant detachment by flow (Meyer cited by Rapp, 1998). Soil is detached by headcut advance from knickpoints (De Ploey, 1989; Bryan, 1990), rill slide sloughing and hydraulic shear stress (Foster cited by Rapp, 1998) as well as by slumping by undercutting of side walls and scour hole formation (Van Liew and Saxton, 1983). These processes are usually combined into a detachment prediction equation as a function of average shear stress (Foster cited by Rapp, 1998). When the rills develop in the landscape, a three to five fold increase in the soil loss commonly occurs (Moss, Green and Hutka 1982 and Meyer and Harmon 1984). 2.5.1 Vegetative Factors The effects of vegetation can be classified into three catergories: The interception of raindrops by the canopy (DHuyvetter, 1985). Two effects are associated with this. Firstly, part of the intercepted water will evaporate from the leaves and stems and thus reduce runoff. Secondly, when raindrops strike the vegetation, the energy of the drops is dissipated and there is no direct impact on the soil surface. The interception percentage depends on the type of crop, the growth stage and the number of plants per unit area. A well distributed, close growing surface vegetative cover will slow down the rate at which water flows down the slope and will also reduce concentration of water (DHuyvetter, 1985). As a result, it will decrease the erosive action of running water. There is also the effect of roots and biological activity on the formation of stable aggregrates, which results in a stable soil structure and increased infiltration that reduces runoff and decreases erosion (DHuyvetter, 1985). Increased permeability also reduces erosion as a result of in increased water percolation due to better drainage. Stables aggregrates in the topsoil also counteract crusting. 2.5.2 Rainfall Factors Raindrop size, shape, duration of a storm and wind speed interactions controls the erosive power of rainfall (DHuyvetter, 1985). The erosivity of rainfall is expressed in terms of kinetic energy and is affected by various factors. According to Wischmeier and Smith (1965), the intensity of rainfall is closely related tot e kinetic energy, according to the regression equation E = 1.213 + 0.890 log I Where E = the kinetic energy (kg.m/m2.mm) I = rainfall intensity (mm/h) Raindrop size, distribution and shape all influence the energy momentum of a rainstorm. Laws and Parson (1943) reported an increase in median drop size with increase in rain intensity. The relationship between mean drop size (D50) and rainfall is given by: D50:2.23 I 0.182 (inch per hour). The median size of rain drops increases with low and medium intensity fall, but declines slightly for high intensity rainfall (Gerrard, 1981). The kinetic energy of an rainfall event is also related to the velocity of the raindrops at the time of impact with the soil (DHuyvetter, 1985). The distance through which the rain drop must fall to maintain terminal velocity is a function of drop size. The kinetic energy of a rainstorm is related to the terminal velocity according to the equation: Ek = IV2/2 Where Ek = energy of the rain storm I = Intensity V= Velocity of raindrop before impact Ellison (1945) developed an equation showing that the relationship between the soil detached, terminal velocity, drop diameter and rainfall intensity: E = KV4.33 d1.07 I0.63 Where E = relative amount of soil detached K = soil constant V = velocity of raindrops (ft/sec) d = diameter of raindrops (mm) I = rainfall intensity 2.5.2.1 Effect of rainfall intensity on runoff and soil loss According to Morgan (1995), soil loss is closely related to rainfall partly through the detaching power of raindrops striking the soil surface and the contribution of rain to runoff. If rainfall intensity is less than the infiltration capacity of the soil, no surface runoff occurs and the infiltration rate would equal the rainfall intensity (Horton, 1945) as sited by Morgan (1995). If the rainfall intensity exceeds the infiltration capacity, the infiltration rate equals the infiltration capacity and the excess rainfall forms surface runoff. According to Morgan (1995), when the soil is unsaturated, the soil matric potential is negative and water is held in the capillaries due to matrics suction. For this reason, under saturated conditions sands may produce runoff very quickly although their infiltration capacity is not exceeded by the rainfall intensity. Intensity partially controls hydraulic conductivity, increasing the rainfall intensity may cause conductivity to rise so that although runoff may have formed rapidly at relatively low rainfall intensity, higher rainfall intensities do not always produce greater runoff (Morgan, 1995). This mechanism explains the reason why infiltration rates sometimes increase with rainfall intensities (Nassif and Wilson, 1975). 2.5.3 Soil Factors According to Baver et al, (1972), the effect of soil properties on water erosion can be in two ways : Firstly, certain properties determine the rate at which rainfall enters the soil. Secondly, some properties affect the resistance of the soil against dispersion and erosion during rainfall and runoff. The particle size distribution is an important soil property with regards to erodibility. Generally it is found that erodible soils have a low clay content (DHuyvetter, 1985). Soils with more than 35% clay are often regarded as being cohesive and having stable aggregates which are resistant to dispersion by raindrops (Evans, 1980). Evans also stated that sands and coarse loamy sands are not easily eroded by water due to its high infiltration rate. In contrast soils with a high silt or fine sand fraction are very erodible. Erodibility of soil increases with the proportion of aggregates less than 0.5mm (Bryan, 1974). Factors which contribute to aggregate stability include organic matter content, root secretions, mucilaginous gels formed by break down of organic matter, the binding of particles by sesquioxides and the presence of a high Ca concentration on the exchange sites of the colloids instead of a high sodium content (DHuyvetter, 1985). The depth of erosion is determined by the soil profile (Evans, 1980). According to Evans soil horizons below the A horizon or plough layer are often more compact and less erodible. The texture and chemical composition of the sub surface horizon can also have an adverse effect. Normally deep gullies can be cut if the parent material is unconsolidated. If resistant bedrock is near the surface only rills will develop. Soil rich in surface stones are less susceptible to erosion (Lamb, 1950 and Evans, 1980). Stones protect the soil against erosion and also increase the infiltration of the flowing water into the soil. The antecedent soil moisture and the surface roughness are both regarded by Evans (1980) as important soil factors affecting erosion. The ability of a soil to accept rainfall depends on the moisture content at the time of the rainfall event. 2.5.3.1 Factors affecting aggregate stability Soil structure is determined by the shape and size distribution of aggregates. Aggregrate size and strengthe determine the physical properties of a soil and its susceptibility to breakdown due to water forces. Their stability will have a decisive effect on soil physical properties (Lynch and Bragg, 1985). The main binding materials giving stable aggregates in air dry state are the glueing agents in organic matter (Chaney and Swift, 1984; Tisdale and Oades, 1982) and sesquioxides (Goldberg and Glaubic, 1987). 2.5.3.1.1 Aluminium and Iron Oxides The soil used by Kemper and Koch (1966) contained relatively little free iron, although it did contribute to aggregrate stability. Their data show a sharp increase of free iron from 1 to 3%. Goldberg and Glaubic (1987) concluded that Al-oxides were more effective than Fe-oxides in stabilizing soil structure. Al-oxides have a greater proportion of sub-micrometer size particles in a sheet form as opposed to the spherical form of Fe-particles. Shainberg, Singer and Janitzky (1987) compared the effect of aluminium and iron oxides on the hydraulic conductivity of a sandy soil. 2.5.3.1.2 Organic Matter Organic matter can bind soil particles together into stable soil aggregates. The stabilizing effect of organic matter is well documented. Little detailed information is available on the organic matter content required to sufficiently strengthen aggregates with ESP values greater than 5 or 7, and containing illite or montmorrillionite, so as to prevent their dispersion in water (Smith, 1990). High humus content makes the soil less susceptible to the unfavourable influence of sodium (Van den Berg, De Boer, Van der Malen, Verhoeven, Westerhof and Zuur, 1953). Kemper and Koch (1966) also found that aggregate stability increased with an increase in the organic matter content of soils. A maximum increase of aggregate stability was found with up to 2% organic matter, after which aggregate stability increased very little with further increases in organic matter content. 2.5.3 Slope Factors Slope characteristics are important in determining the amount of runoff and erosion ( DHuyvetter, 1985). As slope gradient increases, runoff and erosion usually increases (Stern, 1990). At low slopes due to the low overland flow velocities, detachment of soil particles from the soil surface into the water layer is due to detachment alone (Stern, 1990). Additionally, at low slope gradients, particles are splashed into the air in random directions unlike the case with steeply sloping land where down slope splash occurs (Watson and Laflen, 1985). As slope gradient increases, the ability for surface runoff to entrain and transport sediments increases rapidly until the entrainment by the surface runoff becomes dominant contributing to sediment transport (Stern, 1990). Foster , Meyer and Onstad (1976) presented a conceptual model that showed that at lower slopes, interill transport determined erosion, while at steeper slopes, raindrop detachment determined it. Th uniform bed characteristics of sheet flow transport tend to be replaced by channels because of instability and turbulent flow effects (Moss, Green and Hutka, 1982). There are many empirical relationships relating soil transport by surface wash to slope length and slope gradient. Zingg (1940) showed that erosion varied according to the equation: S = X1.6 tanB1.4 Where S = soil transport cm/yr X = slope length (m) B = slope gradient (%) Studies conducted by Gerrard (1981), showed that plane and convex slopes did not differ significantly in the amount of soil lost by surface runoff, but concave slopes were less eroded. Some researchers such as Zingg (1940) and Mc Cool et al (1987) indicated that soil erosion increases exponentially with increase in slope gradient. The relationship is indicated after Zing (1940) by: E = aSb where E is the soil erosion, S is the slope gradient (%) and a and b are empirical constants. The value of b ranges from 1.35 to 2.0. The other relationship between erosion and slope gradient for inter-rill erosion is given by Mc Cool et al (1987) E = a sin b Q+C Q is the slope angle in degrees A,b and C are empirical constants. However, even if the effect of slope gradient on erosion is well recognized, several studies indicate that the power relationship between slope gradient and soil loss over predicts interrill erosion rate by as much as two or more times (Torri, 1996;Fox and Bryan, 1999), and the relationship is better described as linear. 2.8 Soil Erosion Impacts 2.8.1 Soil Physical Properties Progressive soil erosion increases the magnitude of soil related constraints for crop production. These constraints can be physical, chemical and biological. The important physical constraints caused by erosion are reduced rooting depth, loss of soil water storing capacity (Schertz et al 1984; Sertsu, 2000), crusting and soil compaction and hardening of plinthite (Lal, 1988). Erosion also results in the loss of clay colloids due to preferential removal of fine particles from the soil surface (Fullen and Brandsma, 1995). The loss of clay influences soil tilth and consistency. Exposed subsoil is often of massive structure and harder consistency than the aggregated surface soil (Lal, 1988). Development of rills and gullies may change the micro-relief that may make use of farming machinery difficult. Another effect of erosion is that the manangement and timing of farm operations. 2.8.2 Soil Chemical Properties Soil erosion reduces the fertility status of soils (Morgan, 1986; Williams et al., 1990). Soil chemical constraints and nutritional problems related to soil erosion include low CEC, low plant nutrients (NPK) and trace elements (Lal, 1988; Fullen and Brandsma, 1995). Massy et al (1953) reported an average loss of 192 kg of organic matter, 10.6 kg of N and 1.8kg per ha on a Winsconsin soils with 11% slope. Sharpley and Smith (1990) reported that the mean annual loss of total P in runoff from P fertilized watersheds is equivalent to an average of 15%, 12% and 32% of the annual fertilizer P applied to wheat, mixed crop grass and peanut sorghum rotation practices respectively. Researchers (Massy et al 1953; Lal, 1975) have also reported extensive loss of N in eroded sediments. 2.8.3 Productivity Quantifying the effects on crop yields is a difficult task. It involves the evaluation of interactions between soil properties, crop characteristics and climate. The effects are also cumulative and not observed until long after accelerated erosion begins. The degree of soil erosions effects on crop yield depends on soil profile characteristics and management systems. It is difficult to establish a direct relationship between rates of soil erosion and erosion induced soil degradation on the one hand and crop yield on the other (Lal, 1988). It is well known that soil erosion can reduce crop yields through loss of nutrients, structural degradation and reduce of depth and water holding capacity (Timilin et al, 1986; Lal,1988). Loss of production in eroded soil further degrades its productivity which in turn accelerates soil erosion. The cumulative effect observed over a long period of time may lead to irreversible loss of productivity in shallow soils with hardened plinthite or in soils that respond to expensive management and additional inputs (Lal,1988). 2.8.4 Off Site Effects of Soil Erosion. Effects of erosion include siltation of rivers, crop failure at low lying areas due to flooding, pollution of waterbodies due to the various chemicals brought by the runoff from different areas. Several studies reported the significance of the off site effects of soil erosion on land degradation (eg. Wall and ven Den,1987; Lo, 1990; Robertson and Colletti, 1994; Petkovic et al, 1999) Rainwater washes away materials that originate from fertilizers and various biocides (fungicides, insecticides, herbicides and pesticides) which are applied in large concentrations. They reappear in greatr quantities in the hydrosphere polluting and contaminating the water environment (Zachar,1982;Withers, and Lord, 2002; Verstraeten and Poesen, 2002). Chemical pollution of water mainly by organic matter from farm fields causes rapid eutrophication in waterways (Zachar, 1982;Zakova et al, 1993; Lijklema, 1995). 2.8.5 Soil Erosion Models Modelling soil erosion is the process of mathematically describing soil particle detachment, transport and deposition on land surfaces (Nearing et al, 1994). Erosion models are used as predictive tools for assessing soil loss and project planning. They can also be used for understanding erosion processes and their impacts (Nearing et al 1994). There are three main types of models, empirical or statistical models, conceptual models and physically based models (Morgan 1995, Nearing et al 1994, Merritt et al 2003). It is important to note however that there is no sharp difference among them. 2.8.5.1 Physically Based Models These models are based on solving fundamental physical equations describing stream flow and sediment and associated nutrient generations in a specific catchment (Merritt et al ., 2003). They are developed to predict the spatial distribution of runoff and sediment over land surfaces during individual storms in addition to total runoff and soil loss (Morgan, 1995). Physically based models are also called process based models (Morgan, 1995) as they rely on empirical equations to determine erosion processes. These models use a particular differential equation known as the continuity equation which is a statement of conservation of matter as it moves through space over time. The common physically based models used in water quality studies and erosion include : The Areal Non-Point Source Watershed Environment Response Simulation (ANSWERS) (Beasley et al., 1980), Chemical Runoff and Erosion from Agricultural Management Systems (CREAMS) (Knisel, 1980), Griffith University Erosion System Temp late (GUEST) (Misra and Rose, 1996), European Soil Erosion Model (EUROSEM) (Morgan, 1998), Productivity, Erosion and Runoff, Functions to Evaluate Conservation Techniques (PERFECT) (Littleboy et al., 1992) and Water Erosion Prediction Project (WEPP) (Laflen et al., 1991). 2.8.5.2 Empirical M

Catch-22 and the Theme of Death Essay -- Catch-22

Catch-22 and the Theme of Death    There are many ways for a man to die, but there is no way to bring him back after he has entered the world of dead. Catch-22 is a novel satirizing war, and because of this, it inevitably has a strong underlying theme of death. But unlike many war novels, Catch-22 doesn't use violent depictions of fighting or bloody death scenes to denounce the evils of war; it utilizes humor and irony to make an arguably more effective point. And even more importantly, Catch-22 is ultimately a novel about hope, not death. Although the inevitability of death is still a prominent motif, it eventually leads the main character, Yossarian, to realize that the desire to live is important and also that he can't simply live; he must live free of hypocrisy and oppression.      Ã‚  Ã‚   Nately's whore plays a major part in conveying the message about life and death in Catch-22, even though she doesn't become an important character until the novel nears its climax. Although Yossarian is only the messenger bearing the bad news of Nately's death, Nately's whore holds him responsible and follows him back to Pianosa in an attempt to murder him. Yossarian manages to repeatedly escape from her, but only as long as he continues to disobey the illogical and immoral rules of the military. When he agrees to meet with Colonel Cathcart and Colonel Korn, she catches him and seriously injures him. This may imply that by submitting to the oppression of the bureaucratic military system, Yossarian is only headed towards death and disaster. And in the midst of Yossarian's final revelation and his decision to desert the military, Nately's whore was hiding behind a door, ready to stab him. But ... ...but the desire to live is the most important impulse a man can have. But Yossarian can't live a life of hypocrisy or oppression under the military; this is what finally pushes him to desert. The knowledge that Orr finally paddled all the way to Sweden gives him hope, and he sees the only path he can take to be free. He knows it will be difficult, but he knows there is no alternative for him.      Ã‚  Ã‚   Although Catch-22 is a novel about war, it is not only about death. The message it ultimately conveys is one of hope. Yossarian finally realizes that the basic instinct to survive is the most important quality of a man, and that he must follow his impulse and escape from the military, which will only lead him to his death. Catch-22 may allow the military to do whatever the people can't stop it from doing, but it can't destroy hope.   

Desktop Computer vs. Laptop Computers :: Compare Contrast Technology Essays Papers

Desktop Computer vs. Laptop Computers The invention of computers has made a huge change in human civilization and society, by changing the way people think. Computers replaced jobs and tedious repetitive thoughts that were done by human originally. People became more and more reliant on computers, and thus, computers became essential to our lives. Computers can manufacture products quickly, and eliminate possible human errors. As technology progresses, new ideas have been brought into computer to make them perform more efficiently. Also, scientists and engineers tend to make things â€Å"smaller†, so we can enjoy the benefits from electronic devices anywhere and anytime. Therefore, size and efficiency are two main points for consumers. Desktop computer and laptop computer are representatives for each of these concepts. Although desktops and laptops come from the same origin, they are different in many ways. The history of computers is an amazing story filled with interesting statistics. â€Å"The first computer was invented by a man named Konrad Zuse. He was a German construction engineer, and he used the machine mainly for mathematic calculations and repetition† (Bellis, Inventors of Modern Computer). The invention shocked the world; it inspired people to start the development of computers. Soon after, â€Å"In 1946, John Mauchly and J Presper Eckert developed the fastest computer at that time, the ENIAC I. It was built under the assistance of the US army, and it was used on military researches. The ENIAC I contained 17468 vacuum tubes, along with 70000 resistors, 10000 capacitors, 1500 relays, 6000 manual switches and 5 million soldered joints. It covered 1800 square feet of floor space, weighed 3 tons, consumed 160 kilowatts of electrical power.†(Bellis, Inventors of Modern Computer) These statistics are amazing, but even more amazing is the development of computers. Now in 2005, in this short 68-year period, computer technology has changed its entire look; now, we use computer chips instead of vacuum tubes and circuit board instead of wires. The changes in size and speed are probably the biggest. When we look at computers today, it is very hard to imagine computers 60 years ago were such big, heavy monsters. Desktop computers were commonly used since the late 90’s. The increasing number of applications on desktop computers allowed us to do all kinds of different activities like games, music, video, document editing and so on. In comparison with laptop computers, desktop computers have more stable performance, greater capacities, and throughout history, they have proven themselves more reliable to handle every job they have been assigned.

What’s Nature Got To Do With It? :: Writing Technology Essays

What’s Nature Got To Do With It? I am taking a course in writing technology, and the last thing you would imagine as a topic is how natural writing can or cannot be. Our teacher for this course had us come up with a writing project. We were asked to make twenty words or less using any tool that was natural and did not involve high technology. This means we could not use computers, paints, or markers. In discussing what we could use, the class quickly broke down the options. It appeared almost impossible. We got nothing. This is where begging and pleading for ideas came in to play, and perhaps our instructor is a little financially better off if someone offered him a bribe, who knows.. How could it be done? Why? What would we learn about such an unnatural task that would even relate to the topic writing technology? What I learned rather quickly was that these very questions were all apart of why the assignment was given. What at first seemed to be a pointless exercise really answered these questions in a profound way which I want to share with you today. My hope is that you too get a renewed appreciation for writing and it’s history. In the essay from Pencils to Pixels, Dennis Baron details the world’s journey from the use and making of the pencil to the computer. Barron states that the pencil wasn’t originally intended to be used as a writing device. There’s a bit of information you probably hadn’t heard before. Yes, pencils were actually adopted as a tool by â€Å"note takers.. ..scientists...and others who need to write†. They were taken from artists and adapted it for use as a writing tool ( Dennis Barron 44). And so, in engaging in my project, I found myself thinking of how I could adopt a natural tool and adapt that tool to my writing task. I first thought about writing some letters in water, but I could really find no natural container to hold the water. I could have used some sticks or some type of colored liquid and take a snapshot of it, but there was no natural platform to hold the water. This was not going to work.

Leaders, Managers, Entrepreneurs on and Off the Organizational Stage*

Leaders, Managers, Entrepreneurs On and Off the Organizational Stage* Barbara Czarniawska-Joerges, Rolf Wolff My purpose is to tell of bodies which have been transformed into shapes of different kinds. You heavenly powers, sinee you were responsible for those changes, as for all else, look favourably on my attempts, and spin an unbroken thread of verse, from the earliest beginnings of the world, down to my own times.Ovid: Metamorphoses Abstract Barbara CzarniawsicaJoerges Department of Business Administration, Lund University, Lund, Sweden Roif Woiff Gothenburg Research Institute at the School of Economics and Legal Science, Gothenburg, Sweden This paper explores three crucial roles of the organizational theatre: managers, leaders and entrepreneurs. Changing fashion in the organizational theory debate as well as in organizational practice puts different roles in focus at different times.Organization theory should, accordingly, shift its attention toward studying the contexts in which a given role acquires dominance, in place of an unreflective discussion of the relative functional advantages of each of them. This paper argues that none of the three will ever go out of fashion, as they can be seen as enactments of archetypes, embodying the different fears and hopes of those who create organizations by their daily performance.Leadership is seen as symbolic performance, expressing the hope of control over destiny; management as the activity of introducing order by coordinating flows of things and people towards collective action, and entrepreneurship as the making of entire new worlds. The sociohistorical context needs to be considered as the stage-set wherein these roles gain prominence. Introduction Organization Studies 1991, 12/4: 529-546  © 1991 EGOS 0170-8406/91 0012-0022 $2. 00 Leaders are in, managers are out, entrepreneurs are waiting in the corridor.What orders their appearances and disappearances? In an attempt to answer this question, we propose to an alyze all three roles, not in terms of organizational effectiveness, but as symbolic expressions of collective hopes and fears, played out (‘performed') on the organizational stage. Leaders, managers and entrepreneurs are supposed to serve certain functions in organizations — functions which are ascribed to so-called executive positions. The term ‘executive' comes from the times when managers were supposed to execute the owners' will.The separation of ownership and control (Chandler 1977) complicated this simple relationship, opening the way for discussions on the desired form of the executive role. This debate does not take place in a vacuum; it accompanies, reflects and influences changes in organizational practices and theories. Just which functions and in what configuration changes, both with theories and with time, because the definition of what executive functions should entail changes in line with master-ideas, whose time comes and goes (Czarniawska-Joerges and Joerges 1990).These, in turn, are related to 530 Barbara Czarniawska-Joerges, Rolf Wolff broader changes in the cultural context of organizing (Czarniawska 1986). An ambition to tackle the issues of context leads researchers to obviously relevant aspects such as changes in business cycles or changes in political climate. A study of these can of course, if treated with devotion, completely fill more than one research career, and yet there always remains something unanswered, a phenomenon unexplained, of a kind that conventional organization studies are poorly equipped to grasp.Perhaps the theatre metaphor (Mangham and Overington 1986; Czarniawska-Joerges 1992) would help in describing those ephemeral phenomena. What leads to a change in repertoire of a theatre, a replacement of comedy by tragedy, Shakespeare by Pinter? It is the decision of the management, the wishes of the primadonnas, the current cultural fashion, the economic exigencies — and much more. In the organiza tional theatre, the plays performed vary from one season to another, from one director to another, but the general repertoire seems to be quite traditional, even if it contains both tragedy, comedy and drama.It might be that the actual playwright is our ‘collective unconscious', to use Jung's term (1934); that in our attitudes toward the central organizational roles, i. e. leaders, managers and entrepreneurs we act out archetypes. This phenomenon escapes the analysts' attention because we are used to looking for articulation of archetypes in different spheres — in myths and legends (Hogenson 1987). In this discussion, we are dealing with ‘archetypes of personalities' rather than ‘archetypes of transformation' (Jung 1934/1959: 322).The latter are ‘typical situations, places, ways and means' according to Jung (p. 322), or what some would call ‘scripts' (Mandler 1984). The archetypes of personalities are ‘universal, idealized, larger-than-life symbols that contain the essence of human experience and that help individuals develop an emotionally satisfying picture of the world' (Krefting and Frost 1986: 164). In other words, we argue that the central organizational roles represent wishes and fears shared by organizational collectives; they are symbols which help to ascribe meaning to organizational events. It always seems to us as if meaning — compared with life — were the younger event, because we assume, with some justification, that we assign it of ourselves, and because we believe, equally rightly no doubt, that the great world can get along without being interpreted. But how do we assign meaning? From what source, in the last analysis, do we derive meaning? The forms we use for assigning meaning are historical categories that reach back into the mist of time — a fact we do not take sufficiently into account. (Jung 1934/1959: 317) In what follows we shall try to show that the continuing debate on t hose roles reaches indeed ‘back into the mists of time', and although we limit ourselves to a relatively short span of time there are plenty of traces pointing further back. Next, we shall attempt to demonstrate that the three roles are complementary in the sense that they answer different needs or fears of the collective unconscious. In this sense, no role is ever Leaders On and Off the Organizational Stage 53I out'; they all have their place in our collective consciousness, even if we at times tire of one and become fascinated with another. To bring out the core of these archetypes we shall look for their equivalents in literature and theatre, the traditional fields of symbolic expression. In doing so, we continue and extend the tradition of symbolic interpretation of executive roles (see e. g. Frost and Egri, forthcoming; Gustafsson 1984, 1985; Kets de Vries 1989, 1990a, 1990b; Westley and Mintzberg 1989). LeadersIn 1948, Robert Stodgill attempted to make a list of traits r esponsible for leaders' success, starting with a review by Charles Bird from 1940, which listed 79 traits important for successful leadership, as mentioned in 20 works reviewed. Stodgill updated the list to about 100 traits while observing that different authors did not agree on their importance. When he returned to the topic 26 years later in his book Handbook of Leadership, the number of leadership studies reviewed exceeded 3000 (Stogdill 1974).During the 1960s, the concept of organizational leadership began to shift from persons to behavioural styles and then toward the situational factors. Ghiseili (1963), Fiedler (1964), Bass (1960), and Umanski (1967) were among the best known authors who studied leadership and recommended that the leaders should begin by diagnosing the context of their action and should then act accordingly. By the 1970s, the interest in leaders diminished. There were at least two reasons.One was that, after three decades, researchersfinallyarrived at a conti ngency theory which proclaimed that leaders' success depends on the fit between their personalities (thus incorporating the trait theory), the type of action they choose (the style theory, with its origins in the seminal study by Lewin et al. 1939), and the situation (e. g. Fiedler 1964). This achievement, impressive at the time, was met with some derision twenty years later, when the waves of fashion came and went several times.Wildavsky's comments summarize it very well: ‘Unfortunately, multiplying traits of leaders, times types of followers, times samples of situations, times group interactions has led to more variety than anyone can manage. ‘ (Wildavsky 1984: 18) Another, and probably more important reason for abandoning the role of leadership was political frustration at the end of the 1960s. The young Americans saw their favourite leaders killed; the young French decided to remove their old, unpopular leaders themselves. McClelland's article on ‘Two faces of power' (1970) is a vivid example of anxieties suffered by the older generation in the U.S. when the youth rejected the traditional authority and the conventional career paths. According to this study, the graduates of Harvard and other schools did not want to be leaders anymore, seeing a dark face of power even behind the innocent organizational titles. 532 Barbara Czarniawska-Joerges, Rolf Wolff Managers Thus in the 1970s, charismatic leaders were distinctly out of fashion, and yet there was still a need for some sort of authority expression in organizations. The unpretentious ‘managers' took the place of leaders.However, ‘Fayol's fifty year old description of managerial work was no longer of use', observed Mintzberg (1971) in an early report from his famous study of the tasks of managers. A new approach was needed and the most typical model for a manager of the 1970s was perhaps Drucker's (1970) ‘effective executive'. The effective executives had no charisma what soever. The organizational reality pushed them towards ineffectiveness. Their time belonged to everybody else. They were forced to focus on operational exigencies to the detriment of reflection and strategic thinking.They were blinded by the walls of organizations, cutting off the worid outside. They were dependent on what other people did or did not do. To all these harassed people, Drucker formulated a message — a list of practices allowing for an increase in effectiveness, a set of pragmatic prescriptions on how to manage one's time, how to use accessible resources and how to make decisions (Drucker 1970). Problem-solving capacities were more important than social skills and decision-making ability conquered charisma, at least for a while.But power was again noticed, lurking behind this depersonalized, institutional facade. It has been said that the management-oriented researchers, like the early rationalist organization theorists, ‘. . . believed mankind had to shif t from the government of men to the administration of things, as their precursor Saint-Simon had claimed; and they felt they were achieving their aims by emphasizing financial stimuli and technical controls instead of human leadership. The delusion that they had suppressed power relationships prevented them from understanding the true nature of their own actions. ‘ (Crozier 1964: 146)In a sense, this is the same accusation as the one formulated eariier against the leaders, but with a different rationale behind it. While leaders did not understand the true nature of their actions, blinded by power, the managers were blinded by an illusion that they were free from power. This issue appears in the debate on both sides, pro-leaders and promanagers. The advocates of leadership say that there is so much power in organizations that it must be officially recognized, whereas the defenders of management tend to say that there are enough power games in organizations without giving them a n official status.To leave this circle, let us introduce a third voice. Entrepreneurs The story goes that long before there were any leaders or managers in the companies, there were entrepreneurs. These entrepreneurs created, in fact, the world of business organizations as we know them today, employ- Leaders On and Off the Organizational Stage 533 ing not so much charisma or intellectual capacities as something else: willpower. Let us thus make an excursion ‘into the mists of time'. In 1921, Josef Schumpeter published an article on the Unternehmer — the entrepreneur.In this not very well known article, he explored the character of the business company from a historical point of view, the function of the entrepreneur and finally the ‘modern' entrepreneur. Schumpeter saw the origins and functioning of companies as being based on two correlated facts: on the one hand, the property rights over the means and results of production; and, on the other, what he called a â €˜business mentality'. The latter led to the development of production techniques, a capitalist economic calculation and market communication structures.The combination of this capitalist mentality and capitalist property rights produced business companies, which became crucial elements of the contemporary cultures, but even more — they were, without doubt, ‘the basis for and the condition of such cultures' (Schumpeter 1921: 47). Thus, a given type of motivational force creates a given type of organization, which results in a given type of culture that, in turn, encourages such motivational forces and permits such organizations. When analyzing the 18th century, one can see entrepreneurs functioning both as employers and owners of capital.Schumpeter, however, had already noticed that these functions can be and are different, and that in modern companies one encounters two different types of people: managers and entrepreneurs. Management, according to Schumpeter, is a function consisting of control, of guaranteeing discipline and introducing order; a function requiring considerable daily, bureaucratic work. This function, necessary as it is, does not embody what is really characteristic of the capitalist economy. The importance of the entrepreneur is not the management of an existing company but the creation of such a company.Schumpeter perceived entrepreneurship as a specific case of social leadership. Such ‘social leaders' are not outstanding in their task abilities, but in their willpower. This willpower can be translated into contemporary language as ‘initiative', but, in this case, not an initiative of thought (for example, conception of new ideas), but an initiative of action. The core of entrepreneurial motivation is similar to that of leaders, but entrepreneurship mainly fits contexts which are new and cannot be dealt with by means of experience or routine.Entrepreneurship is leadership in exceptional situations and, we might add, is most likely to entail the creation of such situations. Schumpeter stressed repeatedly that entrepreneurship is never a matter of individuals only. It is a phenomenon which has to be analyzed and identified within a complex conglomerate of factors. In saying this, interestingly enough, Schumpeter seemed to anticipate the growing interest in what Mintzberg (1983) calls ‘configurations': complex, dynamic contexts where simple contingencies are not of much use. 34 Barbara Czarniawska-Joerges, Rolf Wolff This does not mean that one should neglect other functions. Any economy, at any time, is performing on the basis of existing experiences and routines. Therefore, there will always be a function which has to do with the supervision of these processes (and which we call ‘management'). Management, or the routine behaviour in production and business, enables economies to deliver promptly and act in accordance with the requirements of systems which are highly rational and therefore predictable.On the macro-level, though, many processes constantly change their situational equilibrium. There is a continuous growth of population and the means of production. There are also non-economic developments which are changing the economy: social developments, political influences, and so on. On the micro-level, the equilibrium ceases to exist when individuals see new possibilities, and strive to implement the innovations they have in mind. The concurrence of macro- and microchanges creates room for entrepreneurs.Paraphrasing Schumpeter's ideas in social constructionist terms, one can say that entrepreneurs are people who are the first to see a crack or aflawin a social construction of economic reality, and to interpret it as an opportunity to actualize their ideas of what the world should look like. As long as this vision is not shared by others, they have to live with an individually constructed reality, which is a heavy burden to bear. What seem to be anecdotal stories of mad inventors and innovators might be actually quite true, in the sense that the unsuccessful inventors are people whose reality did not become socially confirmed.Those who succeeded, though, are the makers of our worlds. Leadership Revisited The neo-conservatism of the 1980s brought to Europe, from beyond the ocean, various nostalgic notions such as ‘free market' and ‘leadership' (as opposed to ‘negotiated economies' and ‘codetermination', the keywords of the 1970s). As far as leadership was concerned, organization theory did not go far beyond Stogdill: offering many definitions, many brands of leadership and varying recipes for success (see e. g. Maccoby 1981; Bass 1985; Bennis and Nanus 1985).But it is ‘charisma' and ‘visions' that count most. Bernard Bass asks dramatically: ‘What does Lee Iacocca have that many other executives lack? Charisma. What would have happened to Chrysler without him? It probably would have gone bankr upt. ‘ (Bass 1984: 26) To which Robert B. Reich answers: ‘Many Americans would prefer to think that Lee Iacocca single-handedly saved Chrysler from bankruptcy than to accept the real story: a large team of people with diverse backgrounds and interests joined together to rescue the ailing company. ‘ (Reich 1987: 82)Leaders On and Off the Organizational Stage 535 Reich points out that public opinion would like to see lacocca as an entrepreneur, a solitary world-maker, rather than a leader who represents a team of people joined in a common effort. His critique aims at the public veneration of world-makers, based on nothing more than their own claim to fame. What is interesting to us, however, is the fact that Reich stresses the difference between the entrepreneurs as solitary worldmakers and leaders who actually lead other people toward a common vision.It has been repeatedly stressed, especially in analyses of political leadership, that leaders express and embody the wishes of their followers rather than impose those of their own. The romanticizing tradition, which Reich criticizes, tends to equip the heroes of the day with the capacities of leaders, entrepreneurs and managers all rolled into one, where they lead the masses to worlds of their own making, waiting for nature to cooperate. In practice, however, not only should the three roles be divided among different people, but even their performance should be brought much closer to reality.If one talks to people employed by organizations led by charismatic leaders, one discovers that they learn about their leaders' visions from the mass media (sometimes from internal videotapes) and that leaders themselves, busy in the TV studio, only have a vague idea of what is happening in their organizations (Schwartz 1989). Organizations are run with the help of Standard Operating Procedures — of which culture is perhaps the most powerful — and impersonal control processes, the latter initiat ed and fed by many different actors, none of whom accepts responsibility for the actual course of events.The remaining pockets of autonomy are filled with individual creativity and self-control which rarely comes from the leaders (on leaders' necessary distance from organizational action, see Brunsson 1989). So, what is leadership all about? In 1978, at the dawn of the new leadership era, a curious book was published, entitled Leadership: Where else can we go? (edited by McCall and Lombardo), which included contributions from the greatest authorities in the field (Jeffrey Pfeffer, Karl Weick, Louis Pondy). The articles challenged all the conventional visions of leadership and came up with new images.The most famous of these was perhaps Pfeffer's article ‘The ambiguity of leadership'. Pfeffer stated that there was not enough evidence to indicate ‘either the effect of leadership or, more significantly, the conditions under which leadership might be expected to have more or less impact on organizational outcomes' (Pfeffer 1977/1978: 23). Leaders serve as symbols representing the personal causation of social events. Such personal attribution of causality is a confirmation of the feasibility to control events, one of the most important stakes in human beings' fight against destiny. Occupants of leadership positions come to assume symbolic value, and the attribution of causality to those positions serves to reinforce the organizational construction of meaning that provides the appearance of simplicity and controllability. ‘ (Pfeffer 1977/1978: 29) 536 Barbara Czarniawska-Joerges, Rolf Wolff Creating this ‘illusion of control' over fate (Brunsson 1989; Czarniawska 1985) lies at the core of leaders' symbolic performance. Leadership should be seen as a political, symbolic process and understood and evaluated in this perspective.While accepting this postulate, we propose to extend the symbolic perspective to the two other roles: entrepreneurs and managers. Entrepreneurship Reconsidered The late 1980s saw a revival of a long forgotten role: that of the entrepreneur, which, for a while, seemed to be petrified in one epoch: that of early capitalism. The contemporary version of this role, embedded into monetary supply-side capitalism, is well described by Kaplan: ‘To get things done through individuals striking out on their own' (1987: 86). The role is ven better understood when contrasted with that of ‘drones' (Reich 1987), that is, those who keep the empires and the big conglomerates going. Entrepreneurs, in the 1990s as in the 1880s, create new social and organizational realities. They work against the existing social structure, not by opposing it by e. g. political means, but by behaving as if the existing structure did not exist. By ignoring the established ways of thinking and action, they make dreams come true. Drones are then the carriers of entrepreneurial ideas. ‘Entrepreneurs' and ‘drones' ali ke represent two extreme personalities, born by two extreme social realities.Today's societal and economic structures tend to moderate both. On the one hand, revolutionary innovation became complex and inordinately costly; on the other, the everyday running of empires requires innovation and social change. Also, the individualism of entrepreneurship contrasts with the realities of everyday life and family structures, at least in the western industrialized part of the globe where we live and work. The freedom for acting out male dreams is curbed by women's emancipation, followed by changing division of work at home, and women's attempts to acquire managerial positions.The dual career problems and ‘glass ceilings' discovered by women in the corporate context leads to more and more women opening small companies of their own. A growing proportion of entrepreneurial businesses in Europe and Africa have been established by women. History will show whether these new entrepreneurs wil l also fall into the luring trap of empire building supported by traditional economic success criteria, or whether they will redefine entrepreneurship by tying it to different archetypes. IVIanagement Defended ‘. . . he executive leader is not a leader of men only but of something we are learning to call the total situation. This includes facts, present and potential aims Leaders On and Off the Organizational Stage 537 and purposes of men. Out of a welter of fact, experience, desires, aims, the leader must find the unifying thread. He must see a whole, not a mere kaleidoscope of pieces. He must sec the relation between all the different factors in a situation. ‘ (Follet 1949: 51) It was with these words that, as early as the 1940s, Mary Parker Follet tried to defend the need for management — rather than just for leadership.In the 1970s, Zaleznik launched the insightful thesis that while leaders are needed in times of crisis and change, managers represent the every day rationality of welfare and affluence (Zaleznik 1977; see also Czarniawska-Joerges 1989). Machiavelli, it seems, wrote for managers and not for leaders. Leaders ‘sometimes react to mundane work as to an affliction' (Zaleznik 1977: 201). ‘They may work in organizations, but they never belong to them' (1977: 205). The 1980s brought in a heavier assault: managers lacked not only leadership but entrepreneurship as well.Always a gallant knight of management, Peter Drucker asserts that they are all the same: ‘Management is the new technology (rather than any specific new science or invention) that is making the American economy into an entrepreneurial economy (. . . ) Entrepreneurship requires above all application of the basic concepts, the basic techne, of management to new problems and new opportunities. ‘ (Drucker 1985: 17) The concept of ‘intrapreneurship' (Pinchot 1985) is, in fact, the most extreme attempt to join management and entrepreneurship in the service of large organizations.Roger Kaplan comments drily: ‘For society to work, you need more than robust little capitalists' (Kaplan 1987: 89). Managers stand for rationality, as Zaleznik rightly pointed out, and they have not disappeared. As late as 1986, Hales asked again ‘what do they do? ‘ on his way to ‘clarification and synthesis between managers' behaviour and the management function' (Hales 1986: 112). We shall now look at all three from a symbolic perspective only. In this endeavour, we shall look for help in archetypical personages known from belles lettres. This is, however, an illustratory device, and is arbitrary in character.The readers are encouraged to look for other images or metaphors which render explicit that which the archetypes project into perceptions of executive roles as designed by both the actors and their audience. Why Are Leaders So Attractive? As we see it, the most appropriate figure representing the leader's role is that of Moses. It embraces, for example, the three leadership archetypes distinguished by Frost and Egri (forthcoming): The Warrior, the Healer and the Magician. A perceptive analysis of Moses' political leadership, rendered by Wildavsky (1984), provides a good example of what is expected of a leader.It took Moses 40 years to take the Jews to their land, although 40 days would have been enough, but he had everything 538 Barbara Czarniawska-Joerges, Rolf Wolff that a leader should have: a visioti, a will to lead, atid a cotitact with God. We do not intend to follow Wildavsky's intricate reasoning. For present purposes, it suffices to notice that Moses represents the epitome of male and paternalistic leadership (a nursing father, Wildavsky calls him, although his nursing methods were rather cruel). His fate also indicates the primarily symbolic role of the leader: he never reached the Promised Land, he was not needed there.The problem with Moseses is, that they have a tendency to sacrific e people in the name of obscure external sources of legitimacy. Additionally, common sense and good organization is not their speciality. Moseses are good in crises, but otherwise they are not the most efficient. In everyday life one contacts a manager of a travel agency to go to Israel. Does it mean that leaders are not responsible for what happens, because they do not actually cause it? Edelman answers this question in the following way: ‘They do identify themselves with particular courses of action and inaction and so deserve responsibility for them.But the assumption that leaders have caused the events for which they take responsibility is reductionist because it ignores the consequences of historical developments, material conditions, and interpretations of those conditions. Except as minor elements of a complex transaction, leaders cannot provide security or bring about change. ‘ (1988: 65) An opposite type of leadership failure is the refusal to perform according to a script expected in given conditions. Maybe it is actually the other side of the same coin, that is, an erroneous belief on the part of the leader that he or she is truly a causative factor.What is then perceived as successful leadership, if it is not the act of bringing about a change? It is a dramatic performance which fulfils the expectations of both audience and co-actors, while retaining contradictions in the service of dramatic effect, but limiting negative and threatening aspects to a necessary minimum; and, above all, a skilful use of stage set and a talented improvization, tuned to prevailing moods (see also Westley and Mintzberg 1989). These are very demanding skills; additionally, high visibility and high costs connected to failure contribute to the market value of this role.Last but not least, high salary and high perks prove, in themselves, that the leader is who he is supposed to be: the person who controls fate. The successful performance confirms the accuracy of the attribution. Why Are Managers Least Liked? Like the leader, the manager has also a symbolic function to fulfil: that of introducing and keeping order, opposing entropy. But unlike the leader, he is not given the splendour of a Moses-like performance. He is a Miser, or worse still, a Scrooge, without imagination, with his ridiculous common sense and care for money and things.Leaders On and Off the Organizational Stage 539 There are probably many mythical biographies representing the archetype of a manager. We took the Miser for his obvious similarity to an accountant. Misers are clearly comic characters, and we gladly laugh at them, as much as we need them. In the course of organizational life, however, this laughter becomes often bitter. Misers have a strong tendency to treat people as things. ‘Could anything be more cruel than this rigorous economy he inflicts on us, this unnatural parsimony under which we perforce languish? {The Miser, Act One) This is Cleante speaking t o Elise, but wouldn't we like to join him and La Fleche (‘A plague on all misers and their miserly ways! ‘) whenever we have spoken to our money-controllers? If the great leaders sometimes do a great deal of good by being othewise occupied (speaking to some god or other on some faraway mountain), managers sit at home, and manage: ‘Let us have you all in here. I want to give you instructions for this evening see that everybody has his job. Come here. Dame Claude, we'll start with you (. . . ) Your job is to clean up all round, and do be careful not to rub furniture too hard.I'm afraid of your wearing it out. Then, I'm putting you in charge of the bottles during the supper. If there's a single one missing or if anything is broken I shall hold you responsible and take it out of your wages. ‘ (Harpagon, The Miser, Act Three) A manager would, of course, find out the shortest way between Egypt and Israel and the cheapest means of transportation, and where would we be with our legend? Boland and O'Leary's (1988) amusing and insightful analysis of images of accounting in advertising illustrates this point very well.The advertisement artists attempted to project an image of a creative controller supported by clever machines but the laughable picture of a man with sleevelets and glasses always crept in. The enemy of creativity and change, the Miser nevertheless symbolizes order, the value which is just as indispensable to organization as control over the fate which Moses promised to his people. At any rate, manager is the one with the truly economic mind, ridiculous as it might seem to all who care about higher things. Why Are Entrepreneurs Admired and Feared? Who are entrepreneurs in terms of their dramatic performance?It is difficult to say as, unlike leaders and managers, who are limited to the political and/or organizational stage, entrepreneurs represent an everyman's dream of the successful life. They are Columbuses, treasure-hunters and Ho ratio Alger's heroes all in one. Their task is to create new worlds, often with a mainly pecuniary interest in the background. In a sense, their play is most often a tragedy, while leaders come from a drama and managers from a comedy. They might become Macbeths if things go wrong, but also inventors like Faust, who wanted to be immortal and succeeded — indeed, it depends on very individual moral judgement as to 40 Barbara Czarniawska-Joerges, Rolf Wolff whether we see Faust as a failure or as a total success. When successful, entrepreneurs acquire God-like (or Satan-like) properties in eyes of the rest of the people: those who can create worlds are to be both worshipped and feared. In the beginning was meaning — In the beginning was power — In the beginning was action — (Faust) How can one translate Faust's dreams into modern economic terms? One possibility is some version of the American Dream, joining the archetype of the adventurer and the entrepreneur . Take, for example, the story of Uncle Jake.In 1929, Uncle Jake left his family home and the horse-breeding farm inherited from his father in Connecticut for Alaska. His mother and friends stayed behind — that is, those friends who did not commit suicide after the Great Depression. The crash did not, however, influence Uncle Jake, neither economically nor psychologically: his optimism seemed enhanced by the dramas around him. This is how John Hawkes' epos Adventures in the Alaskan Skin Trade (1942) starts. It builds up a character similar to Ragged Dick and other Horatio Alger stories, but makes it clear that the economic success is only a means and not the end in itself, as in Faust.Ragged Dick, for example, was a self-made man, the intrepid capitalist, a person who became rich and made others happier by gambling on a new product or innovation. But Uncle Jake never got really rich. He stands for freedom, creativity and dream-building. The materialistic character of the drea m has to do with another aspect of the American Dream — success as measured by money (which in old Europe was usually measured by pohtical influence). The social costs Jake created by going to Alaska were enormous.He barely noticed his wife's death; his daughter became a prostitute (there were not many ways for symbolizing women's failure in life in those days) until the day when she managed to free herself from his influence and could reflect on her father: ‘He was an artist of adventurous life. The exclusivity of the adventure was more important to him than the treasures he constantly promised to me and my mother'. In the eyes of the daughter Jake was not an entrepreneur at all. He was only speaking as such. We are reminded of Iacocca again: has he created a world or did he only speak as if?In a radical thought of Goodman (1978), this difference is immaterial. Until somebody comes with a better story, Iacocca will remain the author of Chrysler's success in the eyes of the public. In his incisive analysis of the case of El-Sayed (the former chairman of a Swedish company who, after a dazzling success, ended up in prison), Kets de Vries observes: ‘All entrepreneurs need dreams, but in dreaming they are not always effective in distinguishing fact from fancy' (1990a: 683). When they succeed, this very trait is seen as a source of their success. Leaders On and Off the Organizationai Stage 541When they fail, they fail for the same reason. The line between a ‘dream' and a ‘distortion of reality' is a tentative one. But all of them, Fausts and Jakes and Dicks, have one thing in common; they leave behind a trail of broken hearts, crushed realities and, in general, extremely heavy costs (they are no Misers! ) In order to better contrast entrepreneurs with managers we can take another real-life but mythologized example, that of Columbus. As 1992 comes close and both Seville and Genoa are preparing for great celebrations, it becomes clear t hat Columbus ‘discovered' America due to his ignorance and mythomaniac tendencies.An Italian physician with a passion for geography told him, on the basis of several wrong estimations, that it is feasible to reach India by going there on an Eastern route. It has been said, by Columbus apologets, that he discovered America whereas other, better educated entrepreneurs did not. Actually, they did not because they were managers — in the positive sense of the word. Apparently, the Portuguese navigators knew very well that such a continent existed, had all the estimations correct, and planned the discovery of America as a next project after having reached India via the Western route.Whereas most of the Columbus biographers ridicule mental rigidity and lack of intuition on the part of the ‘managers' from the Portuguese School of Navigation, the more mundane interpretation would have it that they did not go to India via America because they knew it was impossible. As an a dministrator of the new land, Columbus and his two brothers gave an incredible show of incompetence and cruelty, to the extent that Ferdinand and Isabella were forced to call them back and appoint a new administrator.Such is then the story of Columbus — a real entrepreneur, as opposed to Columbus as a mythical personage (Mendelssohn 1976), but in both versions one thing is clear: entrepreneurs tend to trample over old worlds in their attempts to create new. Why should they be so hailed and respected, then? Because they also bring change, building new realities on the ruins of the old. Personages and Processes As we have attempted to show, it is an illusion that one role ‘conquers' the remaining two.We could go further and further back and, most likely, find the same (as Crozier's example of Saint-Simon already indicates): theoreticians quarrelling about which role is the best, and practitioners playing all three. The fashion of the day elevates one role above the other and then abandons it again. Now we need order, next we need change, and then we need to control our fate. What shapes the fashion, then? Reading the organization theory debate as it has evolved over the last 70 years, one acquires an impression that a demand for leaders, managers or 542 Barbara Czarniawska-Joerges, Rolf Woiff ntrepreneurs is dictated by organizations themselves — straight to the researchers' ears. Then, in an intellectual discourse about the functioning of organizations, the researchers establish which properties the executives should have. They inform the practitioners about what is desired and the practitioners try to follow norms as well as they can. The next wave of research results and theories brings new developments to light, the theory is perfected and the practice follows suit. Such an egocentric representation can be sustained only as a result of firm isolation from the political, social and economic context of organizing.Indeed, with few and unsyst ematic exceptions, organizational literature neglects what is happening in the world around organizations. Sometimes a simple agent called ‘market' comes into the picture, but even then just as a part of ‘environment' which is, indeed, more and more what organizations managed to enact around themselves. Organizations, the open systems, are for ever immortalized in a closed system of an artificially created frame of reference. We would like to point out that organizations act in historically shaped economic and political circumstances.If we bring these into the picture, the leadership debate can be portrayed, for example, as follows: Figure 1 1920s 1929 1930s 1939-1945 1940s 1950s An Historical Speculation Entrepreneurs Depression (economic crisis) Leaders WAR (poiiticai crisis) Managers Entrepreneurs (economic hope) 1960s 1968 1970s 1973-1975 1980s 1990s Leaders (poiiticai crisis) Managers (economic crisis? ) Leaders Entrepreneurs? The 1920s seemed to herald a recovery f rom the economic disaster of the 1st World War and the entrepreneurs were called for to create prosperity with their innovative thinking. The Great Depression brought an abrupt end to this dream.Frightened and in despair, people called for leaders. And leaders they got: Hitler, Stalin, Mussolini, Churchill, Roosevelt. We shall not plunge into what many historians, on many occasions, have analyzed with delight; was it chance, a historically determined development, or all of those. We assume that people try to attribute meaning both to random events and to planned action. It is this factor that stands for the continuity in the process, and not mechanically connected chains of causes and effects. The war made people wary of leaders and gave rise to operational research in the U. S. A.Managers were also welcome in Europe where a big job of restructuring the post-war economies was started. It became possible to think in terms of economic challenge, not only in terms of economic necessity . Entrepreneurs acquired room to play. Slowly, the Leaders On and Off the Organizational Stage 543 prosperity became feasible and leaders were needed again, to push forward and expand their successes. The imperialist ambitions and the failure of new, democratic leaders brought the political unrest of the Sixties. Throughout the rational 1970s, managers were in vogue, to introduce some order and rationality into the world.The oil crisis, however, left in its wake the realization of a possible world-wide economic crisis. People turned to leaders again. As the crisisfeeling dissolved, however, the leaders were somewhat diminished in importance. It was Gorbachov, at least so long as he behaved as a political entrepreneur, who collected the popularity laurels. This is, of course, only one of several possible stories. We do not claim the monopoly on the one and only true story — rather, we would like to see more historical organizational research that traces down social, and not qu asi-biological (as in population ecology) developments.Additionally, such stories would have to pay increased attention to the rhetorics that are used in telling them (McCloskey 1986). In this paper, for example, we have used what is considered to be a chauvinist language: we have spoken of executives as if they were men. This was done on purpose: the dramatical metaphors gave us an additional insight into a matter that is becoming fashionable now, namely, why are there so few women leaders? Simply, the roles are not the female roles.There are, of course, some convincing performances, especially by female Moseses, such as Ghandi or Thatcher, but nevertheless their performance is reminiscent of Shakespearean times when men performed all female roles: brilliant but artificial. Archetypical female roles are hard to fit into modern organizations: neither Dame aux Camellias nor Mother Svea have good chances, at least not in executive roles. In this respect, the organizational theatre has a very traditional repertoire. Researchers As Theatre Critics The question that concludes our paper and, hopefully, starts a discussion is: What should — or can — researchers do?Shall we contribute to the debate as participants? Shall we attempt to unmask and deconstruct it? Shall we write new scripts or ironize the old ones? Holding to our theatre metaphor, we see our choice as analogous to that facing the theatre critics. We can opt for what we ourselves like best, or prompt the directors to keep the public content, or to keep the public on its toes. Over time, however, we should be able to arrive at a more systematic reflection on the organizational theatre. It would be illuminating to be able to follow the process of ppointing and dismantling the ‘favourites' in the social consciousness; to see when and how people reach to the repertoire of archetypes to exchange the last one for another. This means following not only historical developments, but also the sh aping of fashions, the development of organizational and occupational cultures, the ups and downs of professionalization, and other social pro- 544 Barbara Czarniawska-Joerges, Roif Wolff cesses of sense-making. The leadership debate can thus be seen as a transformation of symbols which both follows and announces other kinds of transformation.Organization research can then evaluate contemporary performances and try to build a theory of organizational theatre in a historical perspective.
