Topic Summary
Chimeras have become one of science’s latest advancements to cause controversy. Chimeras are organisms that are composed of cells from two or more species. Specifically, human-animal chimeras are research organisms whose tissues and organs contain both human cells and their own types of cells. In many experiments, human stem cells are injected into an embryo of another animal in order to create human organs. Xenotransplantation still has yet to be tested, especially in regard to immune rejections, but it provides hope for those who are in desperate need of an organ transplant (Agnew). Chimeras are not only limited to organ transplantation. Besides organ transplants, chimeric organisms are excellent for testing possible treatments …show more content…
But, I can see why people believe chimeras are something of the devil. People associate chimeras with being unnatural and unethical because of the combination of animal and human cells, but I believe it is necessary for the advancement of medicine. It is interesting how people do not realize that many medical breakthroughs, such as vaccines and insulin, were made possible through animal research. And of course, there are many ignorant people who oppose chimeras and other animal research. These are the same people who proabbly do not whine about hurting animals when they are eating them in their meals or when they get vaccines. I do not find anything ethically wrong with making hybrid human and animal organs, because at the end, numerous people will be helped. The result outweighs the sacrifice of animals. I have a friend who had kidney failure and unfortunately, he probably will not going to get a kidney transplant any time soon. He was put on the waiting list, like all the other people who need an organ transplant. He has to get dialysis and it is quite a time consuming process. It would be wonderful to see people continue back to living their normal lives if they could get an organ that utilized their own stem cells and thus, reduce rejection. Unfortunately, chimeras have not been widely accepted because they are not …show more content…
Chimeras may not destroy human genetics.
People assume chimeras used for organ transplantation will open a door to creating humans that will have an unnatural combination of animal and human DNA. If not nearly enough research has been done to test the effects of chimeras, then how can anyone conclude that they are entirely bad? If research demonstrates that the human genome may be interrupted or that organisms are turning very human-like, then research needs to stop. The situation of organisms turning very human like is highly unlikely to happen.
3. Chimeras may not only help with organ transplants, but also with neurological diseases.
Chimera research has made us understand the development neurological disorders. Neurological disorders are quite complex in nature and are very deteriorating. Through human-monkey and human-rat chimeras, scientists can learn about Alzheimer’s, Parkinson’s disease, and ALS. These chimeras are just model organisms for useful research that may save many people’s lives. Yes, scientists already do research on these animals, but with the animal’s own neurons and not human stem cells.

Legends say that due to the loyalty of Pegasus, the Greek God Zeus transformed Pegasus into a constellation when it made its way into the sky. 5.) The Greek legend states that Chimera had a physical appearance of a lion, goat and a serpent and it was a complex creature. She was believed to be a ferocious blaze eating monster and was a terrifying looking beast. Legends say that not only Chimera was a frightening monster, but it was also a threatening opponent in battles. Chimera was able to use the powers of all three (the lion, goat and the serpent) and as a result it made it extremely powerful. Greek mythology narrates that Chimera was actually a female and was then known as “Chimaera”, a term which the Greeks used for a she goat. It is believed that Chimera met its destiny at the hands of Bellerophon, a young warrior, who slayed this monster with the help of Pegasus, the popular winged...

My Little Bit of Country

...talks about the ancient yak, which lived in a foreign place in which he originally does not come from. She is using the yak example to amplify her situation when she is forced to go living in the country with her parents. She felt that she did not belong to the country and she is longing after her previous life in the city in which she finds familiar and safe. The city and Central Park illustrates the beauty and the good things while the country portraits the ugly and not so welcoming environment as a contrast. Beauty vs ugly. Good vs bad. Everything vs nothing. She is describing the city as a romantic place of dreams and prosperity where everything is possible and by the hand, you just have to grab the opportunities the city and the environment is giving you. Her father was an artist and the short stories he wrote was the beginning of his masterful portraits of the city and the suburbs. It was stories about long lost world of New York City, when it was filled with river light and when everyone wore a hat. Her parents dreams about living in the post war American chimera in a house with a white-picked fence, instead of living in their rented two-bedroom apartment.

In 1885, the Japanese government announced it would be sending six hundred immigrants to Hawaii. Many who crossed the frontier were financially distressed and viewed “themselves as dekaseginin—laborers working temporarily in a foreign country. Their goal was to work hard in order to ‘return home in glory’ after three years”(44). Many immigrants had the goal of working only a short time quickly returning back to Japan with their acquired sum of money.

Human Resource Management

...Business strategies and human resource management: uneasy bedfellows or strategic partners? John Purcell University of Bath Bath BA2 7AY 01225 386567 J.Purcell@bath.ac.uk 1 Business strategies and human resource management: uneasy bedfellows or strategic partners? One of the assignment questions for this year’s class studying ‘Strategy and Human Resource Management’ (a very popular course) was: Does, and should, competitive strategy determine the design of a firm’s HR system? Give illustrations to support your answer. One of the great advantages in working in a university which has top students is that you can ask them questions you are not quite sure how to answer yourself! The best students gave clear examples of such a link and then got stuck in to the ‘should’ part of the question often noting the critical difference between competitive strategy and business strategy. Some even went further into corporate strategy, the resource based, and knowledge based view as well as ethics, culture and institutional setting. Surprisingly none of them questioned what was meant by a firm’s HR system. I will follow the same line of argument in this paper with thanks to the students, very few of whom have any intention of becoming HR professionals. We start with some of the classics in strategy and HRM, go on to look briefly at some major studies, or the ones that have influenced my thinking. Thereafter the paper notes the problems with the assumed link with competitive strategy as a dominant...

Resistance to Change, Annotated Bib

...Resistance to Change John Caudill Webster University MNGT 5590 Dr. Kevin Henson Abstract The topic I researched was organizational change. My search criteria were limited to ABI/Inform, for peer-reviewed, full text documents, and scholarly journals. I didn’t have a specific time frame. However, most of the articles are within the last 5 years. Some of the search keywords used was organizational change, organizational behavior, and resistance to change. The results of the article analysis found that organizational change is a very complex process. Leaders, managers, change managers and employees have a lot of factors to consider and find solutions for in order for a change to be successful. Some of the common reasons that caused changes to fail are; employee’s attitudes, lack of employee empowerment, forcing employees to change the status quo, employees felt threatened by the change, perceived loss of jobs, new boss, new responsibilities, employees don’t understand the intent of the change, change doesn’t make sense, past experiences and group dynamics play a part. Resistance can be overt or covert. The differences in value congruence and organizational culture of small working groups, the individual and the organization as a whole must also be considered. In order for the change to be a success the leaders must study, analyze, and develop the plan around these conditions. The plan has to be well thought out, the intent and goals understood by the employees...

Ethics and Intuitions

...James Rachels, John Rawls, Jonathan Haidt, Joshua D. Greene, neuroscience, trolley problem, utilitarianism 1. INTRODUCTION In one of his many fine essays, Jim Rachels criticized philosophers who ‘‘shoot from the hip.’’ As he put it: The telephone rings, and a reporter rattles off a few ‘‘facts’’ about something somebody is supposed to have done. Ethical issues are involved – something alarming is said to have taken place – and so the ‘‘ethicist’’ is asked for a comment to be included in the next day’s story, which may be the first report the public will have seen about the events in question.1 In these circumstances, Rachels noted, the reporters want a short pithy quote, preferably one that says that the events described are bad. The philosopher makes a snap judgment, and the result is 1 James Rachels, ‘‘When Philosophers Shoot from the Hip,’’ in Helga Kuhse and Peter Singer (eds.), Bioethics: An Anthology (Oxford: Blackwell Publishers, 1999), p. 573.

Avoid News

...Avoid News Towards a Healthy News Diet By Rolf Dobelli Prologue This article is the antidote to news. It is long, and you probably won’t be able to skim it. Thanks to heavy news consumption, many people have lost the reading habit and struggle to absorb more than four pages straight. This article will show you how to get out of this trap – if you are not already too deeply in it. of what we are designed to handle. This leads to great risk and to inappropriate, outright dangerous behavior. In the past few decades, the fortunate among us have recognized the hazards of living with an overabundance of food (obesity, diabetes) and have started to shift our diets. But most of us do not yet understand that news is to the mind what sugar is to the body. News is easy to digest. The media feeds us small bites of trivial matter, tidbits that don’t really concern our lives and don’t require thinking. That’s why we experience almost no saturation. Unlike reading books and long, deep magazine articles (which requires thinking), we can swallow limitless quantities of news flashes, like bright-colored candies for the mind. Today, we have reached the same point in relation to information overload that we faced 20 years ago in regard to food intake. We are beginning to recognize how toxic news can be and we are learning to take the first steps toward an information diet. This is my attempt to clarify the toxic dangers of news – and to recommend some ways to deal with it. I have now gone without...

Busines and Society

...BUSINESS AND SOCIETY INTRODUCTON With increasing urgency, market and social forces are rewriting the roles and responsibilities of business as well as its strategies. Though the profit motive of business is understood and accepted, people do not accept it as an excuse for ignoring the basic norms, values, and standards of being a good citizen. Modern businesses are expected to be responsible towards the community resources working toward the growth and success of both their companies and their communities. Business ethics can be examined from various new perspectives, including the perspective of the employee, the commercial enterprise, and society as a whole. Very often, situations arise in which there is conflict between one or more of the parties, such that serving the interest of one party is a detriment to the other(s). For example, a particular outcome might be good for the employee, whereas, it would be bad for the company, society, or vice versa. Social responsibility of business ethics and consumer right are the influential aspects of the business and society relations. The social responsibility of businesses to the society’s interest and resource utilization is determinant to the business success.
