Rogerian Speech Example

Rogerian Speech Example Rogerian Speech – Coursework Example Rogerian Speech Rogerian Speech The cases of abortion have increased rapidly over the past decade. The rapid rise in the number is due to the high cost of living and unwanted pregnancies. There have been controversies on whether abortion should or should not be done. Personally, I believe that in abortion be practiced. Abortion of an unborn child due to an unwanted pregnancy is unethical. Justification for several arguments for abortion is valid. First, when the chances are that the child being born will have a severe mental or physical disability. Additionally, if a doctor proves that the progress of pregnancy will cause a greater risk to the life of the mother and lastly if continuing the pregnancy will result to negative mental or physical abilities of the mother. Only in this circumstances should abortion be done.In cases where a woman gets pregnant, whether from rape or by a mistake, she should keep the child. The people against this belief are for the idea that an unwanted chil d is as good as a dead child. They argue that the birth may terminate the education of the teenage mother and that a baby born out of rape is an abomination. Having the arguments in mind, I believe that killing of a fetus is similar to killing a baby because life begins at conception. Abortion causes intense psychological stress and pain, therefore, is not a good form of contraception. Abortion is further not justified because self-control can prevent pregnancy. Additionally, many Americans are willing to adopt, hence there is no point in claiming that the child is unwanted. I would win the other side by convincing them that I understand their views on the topic, and yet I still stand by my current opinion against abortion. My belief will, hence, appear stronger. From the speech above, the people for the idea of abortion will understand why the other side (against abortion) is stronger in views, hence will adopt by opinions.I have used arguments in Rogerian style in my studies. I wi ll use the form again because it helps to win over the teacher who has opposing views to mine. It proves to him that I understand why he believes in a concept, and yet I opt for my current opinion.ReferencesRobinson, P. (2015). How to Write a Rogerian Essay. The Classroom | Synonym.

Alexander Fleming Discovers Penicillin

Alexander Fleming Discovers Penicillin In 1928, bacteriologist Alexander Fleming made a chance discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain a powerful antibiotic, penicillin. However, though Fleming was credited with the discovery, it was over a decade before someone else turned penicillin into the miracle drug that has helped save millions of lives. Dirty Petri Dishes On a September morning in 1928, Alexander Fleming sat at his workbench at St. Marys Hospital after having just returned from a vacation at the Dhoon (his country house) with his family. Before he had left on vacation, Fleming had piled a number of his Petri dishes to the side of the bench so that Stuart R. Craddock could use his workbench while he was away. Back from vacation, Fleming was sorting through the long unattended stacks to determine which ones could be salvaged. Many of the dishes had been contaminated. Fleming placed each of these in an ever-growing pile in a tray of Lysol. Looking for a Wonder Drug Much of Flemings work focused on the search for a wonder drug. Though the concept of bacteria had been around since Antonie van Leeuwenhoek first described it in 1683, it wasnt until the late nineteenth century that Louis Pasteur confirmed that bacteria caused diseases. However, though they had this knowledge, no one had yet been able to find a chemical that would kill harmful bacteria but also not harm the human body. In 1922, Fleming made an important discovery, lysozyme. While working with some bacteria, Flemings nose leaked, dropping some mucus onto the dish. The bacteria disappeared. Fleming had discovered a natural substance found in tears and nasal mucus that helps the body fight germs. Fleming now realized the possibility of finding a substance that could kill bacteria but not adversely affect the human body. Finding the Mold In 1928, while sorting through his pile of dishes, Flemings former lab assistant, D. Merlin Pryce stopped by to visit with Fleming. Fleming took this opportunity to gripe about the amount of extra work he had to do since Pryce had transferred from his lab. To demonstrate, Fleming rummaged through the large pile of plates he had placed in the Lysol tray and pulled out several that had remained safely above the Lysol. Had there not been so many, each would have been submerged in Lysol, killing the bacteria to make the plates safe to clean and then reuse. While picking up one particular dish to show Pryce, Fleming noticed something strange about it. While he had been away, a mold had grown on the dish. That in itself was not strange. However, this particular mold seemed to have killed the Staphylococcus aureus that had been growing in the dish. Fleming realized that this mold had potential. What Was That Mold? Fleming spent several weeks growing more mold and trying to determine the particular substance in the mold that killed the bacteria. After discussing the mold with mycologist (mold expert) C. J. La Touche who had his office below Flemings, they determined the mold to be a Penicillium mold. Fleming then called the active antibacterial agent in the mold, penicillin. But where did the mold come from? Most likely, the mold came from La Touches room downstairs. La Touche had been collecting a large sampling of molds for John Freeman, who was researching asthma, and it is likely that some floated up to Flemings lab. Fleming continued to run numerous experiments to determine the effect of the mold on other harmful bacteria. Surprisingly, the mold killed a large number of them. Fleming then ran further tests and found the mold to be non-toxic. Could this be the wonder drug? To Fleming, it was not. Though he saw its potential, Fleming was not a chemist and thus was unable to isolate the active antibacterial element, penicillin, and could not keep the element active long enough to be used in humans. In 1929, Fleming wrote a paper on his findings, which did not garner any scientific interest. 12 Years Later In 1940, the second year of World War II, two scientists at Oxford University were researching promising projects in bacteriology that could possibly be enhanced or continued with chemistry. Australian Howard Florey and German refugee Ernst Chain began working with penicillin. Using new chemical techniques, they were able to produce a brown powder that kept its antibacterial power for longer than a few days. They experimented with the powder and found it to be safe. Needing the new drug immediately for the war front, mass production started quickly. The availability of penicillin during World War II saved many lives that otherwise would have been lost due to bacterial infections in even minor wounds. Penicillin also treated diphtheria, gangrene, pneumonia, syphilis, and tuberculosis. Recognition Though Fleming discovered penicillin, it took Florey and Chain to make it a usable product. Though both Fleming and Florey were knighted in 1944 and all three of them (Fleming, Florey, and Chain) were awarded the 1945 Nobel Prize in Physiology or Medicine, Fleming is still credited for discovering penicillin.
