Disregard of Moral Values Lead to Unethical Deeds Essay Example for Free

Disregard of Moral Values Lead to Unethical Deeds Essay This greed for money has crossed the limits of all ethical standards, regard and consideration for fellow men, or sympathy and compassion. All these things seem to have gone with the wind and are among the major casualties of the post-independence period. This development can be considered quite a new one, probably an accompaniment of the modern technological development which is . taking place rapidly in this country, as the malaise has especially afflicted the young and the middle aged people. The increasing attraction towards the modern glamorous lifestyles, big cars and bungalows, gorgeous dresses and jewellery has such effect on people that they would not hesitate to resort tovalues all means, unfair to acquire wealth and all luxuries of life. This mad obsession for reaching the top is the dream of everybody, and as such the moral and ethical values do not seem to have any place. Morality is often defined as the doctrine of actions right or wrong it is synonymous with ethics. Moralists are selfless and preach justice in every sphere of life. If people tend to observe morals, they will constitute a healthy and sound society. Morality knows nothing of the geographical boundaries or distinctions of race or color in modern age, the traditional values which are in themselves moral and symbols of rectitude, have been radically transformed. Most of the principles are in a flux and human convictions based a rich human experience are in the melting pot. Obsessions with circumstances and the peculiar conditions prevailing in a region have proved so overpowering that everything else is thrown overboard. Excessive wealth does not necessarily promote culture and intelligence. In fact, the ostentatious and luxurious living that wealth promotes, causes a notable deterioration in character and conception of values. Rarely do highly intelligent people, famous writers or artiest belong to rich families. Since wealth itself has the habit of diminishing fast, most of those who possess it go to any extent, even to the adoption of unethical practices and dishonesty to acquire more wealth. This leads to further decay and deterioration of character. India’s Poet Laureate, Rabindra Nath Tagore warned. â€Å"Greed of wealth and power can never have a limit; a compromise on self-control can never attain the final spirit of reconciliation.

A Cure for Cancer Essay -- Biology Apoptosis

For years people have been looking for a cure for the devastating disease of cancer. Cancer is the third highest killer in the US with over 2,500,000 victims per year. Oncologists and scientists around the country are researching all forms of cancer in an effort to understand, treat, and ultimately defeat this disease. Already there have been numerous advances in the field, such as chemotherapy and gene therapy. One advance has been the use of a cell process known as apoptosis. By harnessing this normal cell process, scientists hope to have found an effective way to combat cancer. Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign and other tumors are malignant. Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body. Over the past few decades cancer has become a very prominent disease. There are many different types of cancer and many different causes for the the disease. Most cancers are because of a genetic mutation. The most common type occur when a cell is dividing. Proto-oncogenes, which are alleles in a normal cells, mutate to form oncogenes. These oncogenes cause cancer because they do not allow the cells to sel f destruct or become epistatic. There have been several research projects which have been testing epistatis. Transfecting DNA To perform the experiments for this re... ...wth of both normal and malignant cells. The limited research that has been performed using these cells has yielded contradictory results: some results say that the alpha5beta1 integrins destroy cancer cells, other results have shown that cell division and other necessary cell functions have been encouraged by the integrin. But the research has predominantly shown that the results of the expression of alpha5beta1 integrins yield beneficial results in terms of cancer tumor reduction. More research needs to be done, but the knowledge obtained from this experiment that alpha5beta1 integrin prevents premature cell death is an excellent step forward in the fight against cancer. There are untold possibilities of the medical applications of not only alpha5beta1 integrins, but all of the many integrins and cell adhesion molecules that play important roles in cell function.

The Issue Of Internet Dating - 1791 Words

You re newly single (whether it be a divorce or breakup) and are looking for love. Now let s say that you ve ultimately decided to join one of those Internet dating sites. There are a number (and growing by the minute it seems) so you have unlimited choices. I myself found my wife on one that I would not dare mention. Others haven t had as much success for one reason or the other. Which Internet dating site you choose is entirely up to you. There have been countless horror stories recounted here and there. Here are two safety tips (ones I consider crucial) to keeping yourself safe. Rule number one: NEVER, EVER give out your personal information. I made the mistake one time of giving out my phone number. When she first called, things seemed pretty normal. We had a lot in common, made each other comfortable, and genuinely were attracted. So we met for dinner and I kindly told her it wasn t going to work. Obviously she took this the wrong way. Days later the woman called and left a ve ry nasty voice message. Mind you I sort of deserved it, but still she had no right to do this. I called her back, and said not to call. Well she didn t answer. Day after day she would call, apologizing about how she d overreacted. This went on for two weeks (her calling every day) and finally I had to put a block on my phone number. Lesson learned. There are other criteria, which make up personal information such as a home address. I have never done this.
