Effectiveness of Cloud Seeding Research Paper Example | Topics and Well Written Essays - 2000 words

Viability of Cloud Seeding - Research Paper Example Notwithstanding the expanding application, there are questions that have been raised identifying with the innovation and its down to earth utilizes, particularly as to its viability. The point of this paper is to address such inquiries by examining the viability of cloud seeding. Utilization of Cloud Seeding In China, during the period going before the Olympics celebrations, cloud seeding was utilized to cause downpour and day off. This innovation was explicitly applied in Northern China and was fruitful to the degree that in snowed without precedent for Hebei, around Beijing (Moseman, 2009). The Chinese capital had not seen any precipitation before this from the past October. The precipitation framed because of cloud seeding was noteworthy and caused in any event the conclusion of 12 region roadways in or close to Beijing. Cloud seeding for this situation spared China from the aches of the most exceedingly awful dry spell in the country’s history over the most recent couple o f decades. The seeding of mists by the Chinese government to cause the blizzard included the utilization of more than 40 sticks of silver iodide, each the size of a cigarette stick Beijing (Moseman, 2009). ... Along these lines, they will never again be disseminated everywhere throughout the environment as small beads yet pull together into not many large beads. Haze evacuation is significant particularly where high perceivability is principal, for example, in air terminals. Studies have shown the significant level of viability of cloud seeding in expelling haze and mists from influenced regions (Ryan and King, 1997). The innovation is viable in a couple of square miles and frequently very quickly. Lightning concealment has a high monetary incentive to the two people and nature. Helping can cause demise and now and again prompts the start of woodland fires. At the point when clouds are seeded with small aluminum filaments, they will in general scatter a portion of their electrical charges in the cloud. Next to no examination has been directed on the viability of this technique in regard of lightning concealment. Be that as it may, the little exploration directed so far have given promising outcomes (Ryan and King, 1997). Cloud seeding and downpour creation Rain is a significant factor in the creation of plant crops and during the raising of creatures. This is on the grounds that downpour is, as a rule, the fundamental wellspring of water in numerous zones. Indeed, even without thinking about farming profitability, downpour is valuable in that it helps in the guideline of temperatures and in containing dust and improving dampness. Truth be told, in desert zones, for example, the California's Mojave Desert, it is an uncommon asset, its value a long ways incomprehensible. Basically, cloud seeding has been applied in numerous purviews as a water the board procedure, as a rule the innovation being applied with a point of causing precipitation.

Found To Develop Around Regions Of Armpits â€Myassignmenthelp.Com

Question: Examine About The Found To Develop Around Regions Of Armpits? Answer: Introducation Acanthosis Nigricans is characterized as a turmoil of the skin portrayed by hyperpigmentation (obscuring) and hyperkeratosis (thickening) in specific zones of the body. Generally it is found to create around districts of armpits, crotches and neck. Regularly it is confused by patients as decolouration of the skin, which in the end won't escape considerably after fiery scouring. In the past the condition was generally connected with interior danger and other hereditary issue. Ongoing investigations have indicated that in spite of the fact that Acanthosis Nigricans isn't in itself an ailment however is a strong biomarker of less incapacitating issue like weight and insulin opposition. Acanthosis Nigricans is a solid marker of hyperinsulinemia in stout patients and the seriousness of the condition to a great extent relies upon the greatness of hyperinsulinemia and heftiness (Sinha Schwartz, 2007). Hyperinsulinemia prompting this condition is believed to be caused for the most part becau se of receptor and post-receptor deserts in the patient. Despite the fact that the specific frequency of the illness is as yet obscure it has been firmly connected with heftiness and significantly less connected with danger. The most continuous relationship with harm was seen as with gastrointestinal tract disease and gastric malignant growths. Studies report that Acanthosis Nigricans is substantially more typical in individuals with brown complexion pigmentation demonstrating an away from of its relationship with race or ethnicity (Puri, 2011). In any case, the distinction in rate because of racial cosmetics can't be credited exclusively to coordinate causal factors, for example, heftiness or diabetes, a yet to be found hereditary inclination might be assuming a significant job for such disparities. It has been demonstrated that the condition is common in pretty much equivalent extent in the two people and subsequently has no sex forecast. Age is additionally not a huge determinant of the condition as it might happen to happen at any age. Be that as it may, threat related Acanthosis generally happens in old. Neck is the most widely recognized area of the body that is influenced by the condition; other usually influenced areas incorporate lips, eyelids, mucosal surfaces and flexural districts of crotch, knees and elbows (Miller Rapini, 2011). Normally Acanthosis Nigricans is a suggestive, be that as it may, persistent regularly report unsavory sensation over the influenced locale making a urge scratch. Pathophysiology In Acanthosis Nigricans the epidermal keratinocytes are animated and the fibroblasts on the dermal layer multiply more than expected coming about in hyperpigmented plaques for the most part in the intertriginous surfaces of the neck. Variables that influence such multiplication and incitement may directly affect the seriousness of the condition. The specific fundamental cell pathogenesis of Acanthosis is yet to be found, be that as it may, it has been hypothesized that the whole pathogenesis is identified with endocrine or tumor delivering development factors that follow up on the insulin like receptors situated on the epidermal cells of the skin (Krawczyk, Myka?aCie?la Ko?odziejJasku?a, 2009). Epidermal development factors and changing development factors, fibroblast development factors assume a vital job in Acanthosis identified with tumor, affecting epidermal cell proliferation. Changing development factor alpha and epidermal development factor both are found in high fixation in g astric adenocarcinoma cells and at the same time epidermal development factor receptors are communicated in Acanthosis influenced skin cells (Kong et al., 2007). Then again heftiness related Acanthosis includes the activity of insulin like development factors and the hormone insulin itself on their separate receptors on the objective cells. It is most generally connected with insulin obstruction issue, for example, type 2 diabetes, stoutness and polycystic ovary disorder. Further, corpulence and diabetes are regularly comorbid conditions and hyperinsulinemia causes the high liking receptors, Insulin-like development factors-1 receptors to be actuated both by insulin and insulin-like development factor-1 (Wang et al., 2013). This outcomes in higher cell development and expansion. Certain elements demonstrate that insulin subordinate actuation of IGF-1 receptors can freely advance the improvement of Acanthosis. Fibroblasts and keratinocyte express the IGF-1 receptors, insulin can cross the dermoepithelial intersection and enact the previously mentioned receptors and in conclusion it has been demonstrated that seriousness of Acanthosis relies le gitimately upon the fasting insulin levels of the patient. Hyperinsulinemia may likewise by implication cause Acanthosis. IGF restricting proteins, which manage the degrees of IGF-1 available for use, are diminished in patients with hyperinsulinemia bringing about expanded groupings of IGF-1, which thus advances cell development and expansion (Phiske, 2014). The post receptor intracellular pathways identified with Acanthosis are probably going to combine sooner or later, in spite of the fact that the specific interrelationship isn't obviously explained at this point. Unfavorable impact of specific drugs that actuate hyperinsulinemia may in a roundabout way advance Acanthosis (Buzsi, Spi Jermendy, 2011). Injuries may withdraw on cessation of medicine or by regulating the ideal measurement. Particular sorts of Acanthosis may create because of autosomal hereditary deformities, indication of which begins at youth and may settle at a grown-up age. In immune system sickness like foundational lupus erythematosus, which is described by creation of antibodies against insulin receptors may in the end bring about the improvement of Acanthosis. Clinical Features: Histology A few physical clinical highlights can be described with Acanthosis Nigricans. The influenced locales are described by even, hyperpigmented, smooth infections. Skin labels are regularly connected with such torment which are known as Acrochordons. (Kapoor, 2010) Lesions are additionally found at times. Mucous layers of various pieces of the body can likewise be influenced by the condition, for example, oral and nasal pit and throat. Injuries of threatening and benevolent Acanthosis are clinically non recognizable and subsequently conclusion is troublesome. The most widely recognized histological element of Acanthosis is hyperkeratosis which is discovered all patients with the condition. Hyperkeratosis is the clinical term that suggests over thickening of the external layer of the skin, layer corneum. In hyperkeratosis the spinous and granular cell layers experience granular and vacuolar degeneration. It is portrayed by away from of variable size around the core of the upper epidermal cells under the magnifying lens. The dim couloration in Acanthosis is because of this hyperkeratosis rather than the brain increment in melanin pigmentation. Invasion of lymphocytes, plasma cells or neutrophils possibly present in specific cases. Horn pseudocysts are likewise discovered which is described by various basaloid epidermal cells reaching out from the epidermis layer to the dermis and may passess spread or intertwining designs. There are an expanded number of keratohyaline granules on the granular cell layer (Hafner Vogt, 2008). Frequently the u pper epidermis is invaded with provocative particles and expanded quantities of mitoses are likewise watched. Keratinocytes might be found to self-destruct because of the absence of keratin fibers that gives solidarity to the keratinocyte cells and bullae arrangement might be seen because of partition of keratinocytes. Papillomatosis is the second most regular histological or minuscule element of Acanthosis. Anomalous keratinocyte differentionation and development are the most huge clinical highlights of papillomatosis. Keratin16 and Keratin 67 articulation are regularly enlarged bringing about expanded change cell layer and expanded lamellar granules in the layer granulosum. Epidermolytic hyperkeratosis is in some cases found with sores. The epidermal hyperplasis can be arranged by the thickening of the epidermis. Level hyperplasia happens when the whole locale experiences moderate thickening, proriasiform happens when epidermal layers are broadened and papillomatous hyperplasia is described by viral moles that venture upwards. Colloidal iron tissue recoloring shows penetration of glycosaminoglycans like hyaluronic corrosive, all the more regularly in patients with gonadal infections. Net Clinical Features As referenced before Acanthosis Nigricans has trademark clinical highlights of dim, coarse and thickened sin with a smooth surface. In the beginning periods of the condition dim earthy colored/dark pigmentation is seen with checked dryness and unpleasantness that is logically thickened. Various little papillomatous rises perhaps found that gives it the smooth surface. As the illness advances the thickening of the skin lines increment and surface becomes mammilated and wrinkled creating warty excrescences (Brickman, Huang, Silverman Metzger, 2010). Albeit other clinical manifestations are missing, patients regularly report sentiment of tingling close by the influenced locales. The leisions of Acanthosis are dispersed evenly and the most widely recognized in back and sides of neck, axillae, crotch and risk cubital and popliteal regions. In kids the most coomon region influenced is neck when contrasted with axillae. Less normal zones that are influenced incorporate outside genetalia, um bilicus, hand joints, internal parts of thighs and furthermore the rear-end. In extreme conditions the sicknesses may spread to phenomenal districts like lips, areola, conjunctive and oral mucous film. There are a few different conditions that have comparative manifestations to those of Acanthosis Nigricans. A methodology of differential conclusions is basic to recognize the related issue to acquire an extensive thought regarding the condition and configuration suitable remedial intercessions. A portion of the related conditions incorporate Epidermal Naevus, Dowling-Degos malady, Confluent and Reticulated

Word of the Week! Soporific Richmond Writing

Word of the Week! Soporific Richmond Writing Here we have a perfect word for late summer, and just today I heard a BBC reporter use it to describe the weather in a small Cuban town. Weather that hot and humid makes one drowsy, which is the nature of anything soporific. This word can also be used to describe the actions of certain drugs. John Locke, in an example from the OED Online, noted the soporifick virtue of opium as early as 1690. With school soon to begin, we might note that our word can describe the effect of a boring anecdote or lecture. The OED catches that usage well with an example from 1727, Hibernian matrons thus of old, Their soporific stories told. So its more than boring. Not everything that bores you makes you drop off.   But in order to keep you awake, Ill end now. Im feeling rather drowsy myself. This blog will continue all summer, so nominate a word by e-mailing me (jessid -at- richmond -dot- edu) or leaving a comment below.

How to write a research paper

How to write a research paper One of the harsh realities of higher education is the inevitably of writing research papers. Writing a research paper involves more than just finding as much information about a given topic or issue as possible and then presenting a summary of the research. Research papers require students to rely on scholarly sources, of course, but they must also present this material in a logical and systematic fashion together with their own perspectives, views, ideas and thoughts concerning what they have found. This part of writing a research paper can be the hardest for some students because they are uncertain whether they own views about an issue are sufficiently valid or informed to include them, or they are hesitant to express an opinion for fear of being labeled naà ¯ve or even worse. This reluctance may prevent them from expressing their views or opinions as fully as they would like, and it will invariably diminish the quality of the research paper that results. Provided students are tho ughtful in their analysis, though, and support their views with relevant resources, even â€Å"off-the-wall† views can contribute to the overall originality and quality of a research paper.

Day after day, late students are punished or end up in detention due to short passing periods. Having short passing periods can make a student’s grade go down or worse when students are late to class. This can be prevented by extending passing periods to 10 minutes.

A resounding depiction of this use of rhetoric is found when looking at George H. W. Bushs rhetoric in 1990 1991 in regard to The Gulf War. George H. W. Bush stimulates, through rhetoric, the notion that The Gulf War (also known as Operation Desert Storm) was necessary. Consistent themes are found within presidential speeches that shape war rhetoric. Common themes are demonization of the opposition, human rights concerns, and defeating aggression. All of the themes mentioned are illustrated within Bushs rhetoric preceding and during The Gulf War. To illuminate these rhetorical t hemes and argue the incitation of war by George H. W. Bush I will be analyzing two of his speeches: Address on Iraqs Invasion of Kuwait and Announcing War on Iraq. Literature Review   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   War rhetoric, according to Jamieson and Campbell, means the rhetoric by which presidents seek to justify to Congress and to the citizenry their exercise of war powers. Presidential war rhetoric intends to launch invasions, direct invasions, suffice stationing troops, and sell the war. Its imperative to sell the war so that people will fight it and people will fund it. Presidential power, especially war power, has expanded and increased with every decade in respect to rhetoric. Executive war powers have been broadened over time by their exercise, by congressional complicity, and by Supreme Court sanction (Campbell and Jamieson, 2013). The president can overstep his assumed constitutional powers and rights through the use of rhetoric due to the blurred lines of what the president can and cant do. Rhetoric can subdue what might seem unconstitutional as far as influencing the nation or pushing a personal agenda. War rhetoric is a constant power struggle betwe en the President and Congress mediated by The Supreme Court. Presidential war rhetoric is related to the ongoing struggle between the president and Congress, refereed by the courts, over what the Constitution permits the president to do (Campbell and Jamieson, 2013). Presidential entitlements have been into argument because article 1 of the Constitution reserves to Congress the authority to declare War, . to raise and support Armies, . provide and maintain a Navy, . [and] make Rules for the Government and Regulation of the land and naval forces, whereas article 2 defines the president as Commander in Chief of the Army and Navy of the United States, and of the militia of the several states, when called into the actual service of the United States. (Campbell and Jamieson, 2013). The democratic solution to war includes 2 steps: 1) President must request or recommend declaration of war; 2) Congress must declare war through resolution, statute, or declaration of war. The argument of the President being able to take advantage of and exploit their power of war is validated through the evidence of only five officially declared wars. According to Campbell and Jamieson, major military actions in Korea, Vietnam, Kuwait, and Iraq have been carried out without declarations of war, and more than one hundred military ventures involving combat troops have been conducted without any form of congressional authorization. The majority of American wars have been enacted without statutory authorization, a resolution of support, or a declaration of war (Campbell and Jamieson, 2013). It is often argued whether or not a presidents call to war is appropriately in the defense of our nation or an overstep of the nations military capabilities. It is often in question if a presidential decision to go to war is a hasty or responsive decision, rather than a well thought out one. The founders hoped that the rhetorical process implied by the Constitution would ensure that a decision to wage war would be arrived at thoughtfully, not rashly or emotionally (Campbell and Jamieson, 2013). While it is often seen that a president is overstepping his congressional duties by inciting war, it is still a frequent occurrence that is provoked through rhetoric. Despite the change from former to subsequent reasoning of military action, Campbell and Jamieson argue that presidential war rhetoric throughout U.S. history manifests five pivotal characteristics: 1) every element in it proclaims that the momentous decision to resort to force is deliberate, the product of thoughtful consideration; 2) forceful intervention is justified through a chronicle or narrative from which argumentative claims are drawn; 3) the audience is exhorted to unanimity of purpose and total commitment; 4) the rhetoric not only justifies the use of force, but also seeks to legitimize presidential assumption of the extraordinary powers of the commander in chief; and, as a function of these other characteristics, 5) strategic misrepresentations play an unusually significant role in its appeals (Campbell and Jamieson, 2013). It is often found that by including these characteristics in their speeches, the President is better able to legitimatize his intentions in the interes t of the constitutional right to defend the nation. Within war rhetoric it is common for the President to greet his rational deliberation (a constitutional obligation) with recommending Congress to declare war or to authorize the introduction of armed forces (Campbell and Jamieson, 2013). This thoughtful deliberation usually is when the President states that he has talked to international leaders, allies, all of the government, etc. before speaking on the matter. Perhaps one of the most prominent and effective characteristics of war rhetoric is the use of narratives. Narratives are typically what allow the media to further the argument of war and influence the public. The use of narratives allows the President to dramatize and simplify the situation at hand so that war seems inevitable. Narratives often explore the idea of how alternatives might be possible but due to the [dramatic] situation or threat at hand an immediate response is undoubtedly necessary. The narrative typically reframes the conflict as aggression by the enemy, according to Jamieson and Campbell, which legitimizes presidential initiatives as actions to defend the nation. This type of narrative results in a call to action to support the decision to wage war. An extended narrative is often seen in war rhetoric, where the President structures the argument of war by exhausting national values to frame the opposition as a threat to the nation and civilization. War rhetoric narratives often characterizes America as innocent and in favor of good, desiring to help others or taking action in the best interest of others. Narratives tend to differ between presidents based on intentions and motives but remains an essential characteristic of war rhetoric. Following narratives is the third characteristic of presidential war rhetoric that Campbell and Jamieson discuss, exhortation to unified action. It is often found within presidential speeches that incite war elements of unification. This unification element is in large part due to framing the intent behind war being in the best interest of humanity and civilization as a whole. The concept of unification comes with the assumed [anticipative] conclusion that right will prevail (Campbell and Jamieson, 2013). This characteristic will often appear as a president reminding the audience to put parties aside and using unifying terms and phrases like we and my fellow Americans while playing on national values. Exhortation to unified action speaks to the values Americans want to see in themselves and suggests values are threatened. The fourth characteristic that Campbell and Jamieson designate as a necessary element of war rhetoric is investiture as commander in chief. Ultimately, war rhetoric is a rhetoric of investiture (Campbell and Jamieson, 2013) meaning that it is an [arguably] excusable time to expand power as a president and justify why. The president rationalizes this as the time to exercise his right to play the role of Commander in Chief due to the threat of American values and the community. While the original intent of the role Commander in Chief was to repel attack, presidential innovations have created precedents that presidents have used to claim expanded executive war powers (C ampbell and Jamieson, 2013). Another complex modification of this characteristic is the role Congress now plays with the president in waging war. The intent of the Constitution was that the president would go to Congress to request authorization to act as commander in chief, but now the president assumes the role and then asks for congressional ratification (Campbell and Jamieson, 2013). The characteristic that plays a very significant role in war rhetoric is strategic misrepresentation. Strategic misrepresentation is a very dominant trend within Bushs war rhetoric, which will be explored further in this paper. War rhetoric is typically intended to incite immediate action demanding immediate support. This urgent action is attainable through the use of strategic misrepresentation, where the president uses rhetoric to misrepresent the events described in ways strategically related to stifle dissent and unify the nation (Campbell and Jamieson, 2013).

Same Sex Parenting And Parents Essay - 975 Words

This paper discusses same-sex parenting and some of the situations they have experienced. I will be discussing how this same sex pair handles family life, their demographics in relation to class material and Family Systems Theory as well as personal and professional application in their situation. There are a number of same sex parents in society today. Same sex families are no different from other families, but there are a few unique challenges that occasionally arise. Same sex parents still have a very effective style of parenting. I can see how a child’s success still comes from the quality of the parent-child relationships. Demographics: It is difficult to attain a precise count of same-sex parent families in the United States today. I believe this is due to many same sex families are not open about their sexual orientation or family situation. The partners in my interview have been in a relationship for ten years. They have a single child that is a ten-year-old boy. They developed a relationship when the mother was four months pregnant. The mother is thirty-eight years old, and the partner is thirty-five. This relationship was the mother’s and partner’s second serious relationship. Relation to Class Material: This topic will discuss three subjects that I learned in class that relate to my interview questions and answers.

Jamestown Settlement free essay sample

The first permanent English colony in North America was established at Jamestown, Virginia, in 1607. In order to earn quick profits for Virginia Company investors, the settlers wasted no time and immediately began hunting for gold and searching for the Northwest Passage to Asia. According to page forty-two in the American Journey textbook, â€Å"all they would find was suffering and disappointment,† which would foreshadow the years ahead. The colony would soon prove to be an immediate disaster. First of all the settlers neglected to plant crops because they were so eager to find new riches. The colonists had never really planned to grow all of their own food. Instead, their plans depended upon trade with the local Native Americans to supply them with enough food between the arrival of periodic supply ships from England. This quickly caused their food supplies to dwindle and many starved to death. The second mistake the settlers made is that the settlement was located in a swamp. We will write a custom essay sample on Jamestown Settlement or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This soon led to diseases caused by parasites that were there and malaria caused by all the mosquitoes. So the settlers that didn’t starve usually died from disease. Initially Captain John Smith saved the colony through his leadership by imposing order and military discipline. However, certain settlers refused to follow his orders and believed their social status exempted them from manual labor. Just as bad was the failure of the colonists to work together for the common good, or indeed to work at all. The impending hardship was further compounded by the loss of Smith, who became injured in August of 1609 in a gunpowder accident, and was forced to return to England for medical attention in October 1609. This proved to be a major blow because he was most skillful in dealing with the Indians in trading for food. For years there was hardship and suffering in Jamestown, but in 1619 three important developments occurred. The company began to tranport women to become the wives of the planters and intice them to stay in the colony. The same year the first Africans arrived in Virginia and soon became indentured servants. The last major happening was the company created the first legislative body in English America. They were told to establish one equal and uniform government over all Virginia. According to the textbook, this also set a precedent for the establishment of self-government in other English colonies. The early years for Jamestown were full of disappointment, suffering, starvation, and tribulations. There was a constant battle going on with the Powhatan Confederacy and the colonists. Over time the settlers lost the Virginia Company, but eventually had a successful colony thanks to an established government and a marketable tobacco crop. .

The Parable of the Sadhu free essay sample

Bowen H. McCoy’s friend Stephen is quoted as saying, â€Å"I feel that what happened with the sadhu is a good example of the breakdown between the individual and corporate ethic. † Explain what you think Stephen meant by this statement. What is the nature of that breakdown between the individual and corporate ethic as you see it? In the article, Stephen goes on that â€Å"No one person was willing to assume ultimate responsibility for the sadhu. Each was willing to do his bit just so long as it was not too inconvenient. When it got to be a bother, everyone just passed the buck to someone else and took off. † Ask the students if they have ever seen such a situation in their lives? Have the students ever observed student-teams told by the professor for the last team out of the classroom to clean up, turn off lights and lock the door? Yet, when the last team walks out of the classroom, often the instructions are forgotten. We will write a custom essay sample on The Parable of the Sadhu or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Each team may blame other teams for not doing their part. Is it true that individuals tend to lose their responsibility in groups? Is it easier to hide in a group and spread the blame? 2. In reflecting on his discussion with Stephen about the sadhu McCoy says, â€Å"The instant decisions that executives make under pressure reveal the most about personal and corporate character. † Do you think on-the-spot decisions better reflect the character of the decision maker and organization rather than those that might be more thoroughly thought through? Why or why not? On-the-spot decisions reflect our habits and pattern of making decisions. This is why the Greeks argued that virtues must be practiced every day to become a habit. More thoroughly thought through decisions may not be any better than the on-the-spot ones, but may be analyzed to consider the alternatives and consequences. The ultimate decisions of either thought process reflect the character of the decision maker and organization. 3. McCoy equates the parameters of the decision-making process about the sadhu with that in business. He believes there is an interesting parallel to business situations. Explain what you think McCoy meant by this statement. Do you agree with him? McCoy points out that decision making in business is similar to what happened on the mountain: Decisions had to be made based upon what was seen and with outside influences on the processes. It is possible that the big picture may not be seen or considered; the depth or consequences may not be immediately recognized; the situation and policies may be misunderstood; the decision maker may not know of or utilize available resources. Businesspeople must be aware of the risks but cannot run away from all risks in making decisions. Often the true dimensions of the situation will not be comprehended by the manager or all members of the business team. Have the students consider the pros and cons of the parallel. 4. McCoy concludes that the lesson of the sadhu is that â€Å"in a complex corporate situation, the individual requires and deserves the support of the group. When people cannot find such support in their organizations, they don’t know how to act. † What support in organizations do you think McCoy is referring to? If such support is not found, what should individuals do when they have an ethical dilemma such as that in the sadhu case? If the organization does not provide the support to evaluate and resolve an ethical dilemma, then the individual must rely on his own values and decision making models. Below is McCoy’s reflection on the sadhu 15 years later. He notes that Stephen was reacting to the situation from his Christian ethic of compassion while he (McCoy) had a utilitarian response. Neither are the only right responses. Many students will want or state one right response, only. 5. What is the moral of the story of the sadhu from your perspective? McCoy summarized the moral as â€Å"When do we take a stand? † When Do We Take a Stand? By Bowen McCoy I wrote about my experiences purposely to present an ambiguous situation. I never found out if the sadhu lived or died. I can attest, though, that the sadhu lives on in his story. He lives in ethics classes I teach each year at business schools and churches. He lives in the classrooms of numerous business schools, where professors have taught the case to tens of thousands of students. He lives in several casebooks on ethics and on an educational video. And he lives in organizations such as the American Red Cross and ATT, which use his story in their ethics training. As I reflect on the sadhu now, 15 years after the fact, I first have to wonder, What actually happened on that Himalayan slope? When I first wrote about the event, I reported the experience in as much detail as I could remember, but I shaped it to the needs of a good classroom discussion. After years of reading my story, viewing it on video, and hearing others discuss it, I’m not sure I myself know what actually occurred on the mountainside that day! I’ve also heard a wide variety of responses to the story. The sadhu, for example, may not have wanted our help at all – he may have been intentionally bringing on his own death as a way to holiness. Why had he taken the dangerous way over the pass instead of the caravan route through the gorge? Hindu businesspeople have told me that in trying to assist the sadhu, we were being typically arrogant Westerners imposing our cultural values on the world. I’ve learned that each year along the pass, a few Nepali porters are left to freeze to death outside the tents of the unthinking tourists who hired them. A few years ago, a French group even left one of their own, a young French woman, to die there. The difficult pass seems to demonstrate a perverse version of Gresham’s law of currency: The bad practices of previous travelers have driven out the values that new travelers might have followed if they were at home. Perhaps that helps to explain why it was so difficult for Stephen or anyone else to establish a different approach on the spot. Our Sherpa sirdar, Pasang, was focused on his responsibility for bringing us up the mountain safe and sound. (His livelihood and status in the Sherpa ethnic group depended on our safe return. ) We were weak, our party was split, the porters were well on their way to the top with all our gear and food, and a storm would have separated us irrevocably from our logistical base. The fact was, we had no plan for dealing with the contingency of the sadhu. There was nothing we could do to unite our multicultural group in the little time we had. An ethical dilemma had come upon us unexpectedly, an element of dram that may explain why the sadhu’s story has continued to attract students. I am often asked for help in teaching the story. I usually advise keeping the details as ambiguous as possible. A true ethical dilemma requires a decision between two hard choices. In the case of the sadhu, we had to decide how much to sacrifice ourselves to take care of a stranger. And given the constraints of our trek, we had to make a group decision, not an individual one. If a large majority of students in a class ends up thinking I’m a bad person because of my decision on the mountain, the instructor may not have given the case its due. The same is true if the majority sees no problem with the choices we made. Any class’s response depends on its setting, whether it’s a business school, a church, or a corporation. I’ve found that younger students are more likely to see the issue as black-and-white, whereas older ones tend to see shade of gray. Some have seen a conflict between the different ethical approaches that we followed at the time. Stephen felt he had to do everything he could to save the sadhu’s life, in accordance with his Christian ethic of compassion. I had a utilitarian response: do the greatest good for the greatest number. Give a burst of aid to minimize the sadhu’s exposure, then continue on our way. The bsic question of the case remains, When do we take a stand? When do we allow a â€Å"sadhu† to intrude into our daily lives? Few of us can afford the time or effort to take care of every needy person we encounter. How much must we give of ourselves? And how do we prepare our organizations and institutions so they will respond appropriately in a crisis? How do we influence them if we do not agree with their points of view? We cannot quit our jobs over every ethical dilemma, but if we continually ignore our sense of values, who do we become? As a journalist asked at a recent conference on ethics, â€Å"Which ditch are we willing to die in? † For each of us, the answer is a bit different. How we act in response to that question defines better than anything else who we are, just as, in a collective sense, our acts define our institutions. In effect, the sadhu is always there, ready to remind us of the tensions between our own goals and the claims of strangers. References: McCracken, Janet, William Martin, and Bill Shaw.
