Are Steroids Worth the Risk? One of the most controversial issues with all athletes are steroids. How harmful are they? Is it worth the risk to get a competitive edge on the game? Should it be banned from sports? Steroids are not the answer; not only are there physical bad side effects, there are also psychological effects short and long term. The history of steroids dates back to the 1930s, the were taking from male testosterone originally. They were used to treat HIV-AIDS and cancer. They also helped stimulate bone growth and appetite, in order to help those who had trouble with weight gain. An example of this was a man named Barry Tyson who was suffering from HIV and took steroids in order to help build more mass in order to fight off infections from the disease. He noted that, within the first dosage he had taking at night he woke up the next day feeling like a new man and had abundant sources of energy. Some were along theses lines of using it for good medical use and healing it was lost for the benefit of athletes. The effects of steroids are tremendous in both genders. Yes even girls have been caught on steroids to help give them an advantage in sports. The risk that effect boys in the long run are; Testicular shrinkage, blood clotting, breast development, impotence (inability to get an erection), sterility, jaundice (liver damage), shortening of height, heart disease, cancer, and even tumors. Now why would someone want to risk all those long term effects just to get a little stronger. Some would say, Ã¢â¬Å"well I'm just going to use it for a little then I will get off of it. Well steroids is just like any other drug, it is addicting. People try to get off, but once off they realize they cannot get gains as quickly as Palcsik 2 they were before and go back on the steroids thinking just one more time will be fine. After time has passed they never get off and become addicted just like any other drug. Even if you are still skeptic here are some short term effects on boys from steroids: Premature balding or hair loss, dizziness, trembling, seizures, pain when urinating, and even aching joints. Not only are boys effected, but some girls try to get a competitive edge over the fellow athletes. Steroids are not meant to be taken by woman, because a woman's genetics are not meant for male testosterone. Some of the effects on girls are; increased facial hair, development of masculine traits such as deepening of the voice, loss of feminine characteristics, shrinking of breast, and even extreme increased sex drive. These risks are not worth having just so they can become better or close to their competition. Most woman's effects of steroids are irreversible and once one cannot be changed. Another trend found in woman is that when they take steroids they tend to drink more often than usual. This leads to even more liver problems and possible shut down of this organ may be a long term effect. Not only are there physical effects, but there are some psychological effects also. One of the most major factors is Ã¢â¬Å"roid rage. Ã¢â¬ Roid rage is a result of steroids that cause drastic moods swings and aggression. No just little mood swings, they are extreme uncontrolled bouts of anger caused by steroid use. The longer use of the steroids the more so called rages are experienced and to a greater extent. Back a few years ago there was an entertainment wrestler that used steroids excessively. As the years went on he never noticed any rages or irritability. Suddenly one day he snapped in a violent rage killing his wife and strangling his little seven year old son. Other psychological effects are depression, becoming delusional, paranoia, and even problems sleeping. So not only are there all these mental aspects of steroids that can destroy you, but also physical effects too. Many people believe that taking steroids to get the competitive edge is worth it. Look at all these negative effects. The short term results are not worth the extreme damaged caused to athletes body. People also say well steroids shouldn't be illegal in sports, if you choose to take the risk then it is Palcsik 3 that persons responsibility. The answer is no steroids are not okay in sports or at all in daily life. It was initially banned not because it was considered cheating in sports, but because of the unhealthy effects of steroids and the addictions caused by it. Also it is cheating it is not a persons natural ability, it is fake and additives to the body that are naturally there. People might say well people use it when they are sick so it can't be that bad. Steroids should only be used in medicine to help patients that need it because it is controlled by doctors so u cant exceed the amount you are supposed to have. It is a controlled prescription that the doctors understand. Steroids are not the answer for athletes. If you have the raw natural talent then you have what it takes to be a superb athlete, if not then keep trying till it is no longer possible. If it is not meant to be then it isn't meant to be, there is no point in sacrificing your body just for a few years of possible fame or glamor. Also its not even guaranteed that a person will succeed in the what the reason is that they are taking steroids. The question is are you willing to go throw pain and suffering for the rest of your life just for a advantage over the competition for a temporary time?

Fundamental Perspectives and Techniques of Decision Making - Dissertation Example In the contemporary uncertain business contexts, making a decision which has certainly long-term implications on business requires thorough understanding of all possible future situations and more importantly the managerial ability to balance both controllable and uncontrollable parameters (Bhushan and Rai, 2004, p. 3). Managerial decisions are key factors to influence a firmÃ¢â¬â¢s success and failure. Managers need to ensure that their firms are able to continually innovate and get accustomed with changing business environments so that it can maintain a reasonable stance and pace in competitive edge. If managers want their firms to survive in the dynamic and uncertain business conditions, they need to carry out effective decision making processes. ... Creative thinking aims at bringing newer ideas whereas problem solving is directed to find a solution, an answer or a conclusion (Adair, 2010, p. 1). An individual or organizational decision is the end result of much more dynamic processes and a series of activities labeled as Ã¢â¬Ëdecision makingÃ¢â¬â¢. McGrew, Wilson & Wilson (1982, p. 5) stated that the decision maker, in his decision making process, identifies the problem, clarifies particular goals that are desired, examines various possibilities for achieving the desired goal and finally completes the process by taking a definitive choice of action. Decision is therefore an answer to a specific question or some problems or a choice between two more courses of actions. Ahmad, Hasnain and Venkatesan (2012, p.21) described a five-stage process for decision making. It comprises of identifying all alternatives, valuing these different choices according to preferences and potential outcomes, assembling the information, choosing a mong the preferences and outcomes and finally selecting the most favourable and appropriate choice. Decision that has been taken after careful coordination of information, evaluation of potential outcomes and analyzing of various preferences based on advices, suggestions and help of people involved as members in a group-decision making has been found to be very effective in terms of its appropriateness and positive outcomes. Decision making is a cognitive process that involves logical reasoning and creative thinking about choosing a specific course of action that is supposed to bring the decision maker to a certain result. One of the key challenges in decision making is reducing or eliminating the uncertainty. A better way to avoid uncertainty is to collect relevant information before
Journal entry - Essay Example Prior to composing poems and children books, Donald Hall was a teacher; he did not enjoy the job especially when marking the papers of the students. He quit the teaching job to become a poet (Hall 348). Donald Hall provided insufficient information as to how he became a poet. How did he learn that he would enjoy spending the rest of his time at home, writing poems and children books? In addition, he also failed to recognize that it requires a talent for one to be a poet or writer. Not all people are blessed on the same level, and Donald Hall was a gifted individual since he enjoyed writing poems and was gifted in the sector. Through the poems, people were inspired and motivated to change their ways. Nonetheless, not everyone has the capability of using personal interest to earn a living (Hall 349). Therefore, people are forced to work in areas of less interest, to fulfill lifeÃ¢â¬â¢s goals. This has led to a number of people complaining about their careers. Donald Hall could have d iscussed further, how an individual could be able to discover personal interest that could be useful throughout their

Economics cuurent macroeconomic situation - Research Paper Example These figures are significantly showing progress but by no means indicate that things are turning out for the best (Avent, 2010). Unemployment and its direct correlation with inflation clearly show on these figures. This indicates that stimulus packages and the low interest rates provided by the government is showing its effects. Without these, businesses would not venture into accruing capital and entrenchment would ensue. More and more firms and departments are hiring temporary workers including census jobs which will show countercyclical effects. This suggests that confidence and optimism is slowly gaining momentum. It is a clear indication that more needs to be done before the country can truthfully say that it is out of the recession slump. Robert Reich (2010) suggests that only reason the economy is not in a double-dip recession is due to the boosts injected by the government. He further adds that 41,000 new jobs provided in May which mostly consisted of temporary Census workers is not enough. At the minimum, 100,000 new employments are needed every month to cope with the population growth. Apprehensions are now directed over what will happen once these are directly withdrawn from the economy. Policy makers play an integral role in ensuring the health of the economy doesnÃ¢â¬â¢t flat line. The applied easy money policy tools which are apparent in the contingency efforts of the government to stabilize the economy are already in place. It becomes indispensable at the current situation but Ã¢â¬Å"Effectively zero interest rates are creating distortions in capital markets. Monetary conditions need to be back to normal by the time economic slack disappears and inflationary pressures begin to reassert themselvesÃ¢â¬ (Padoan, 2010). Government hand can only go so far before it reverts into prioritizing the need for other programs before money runs out and the Federal Reserve reverts to government

Dra Rod DB 4 - Assignment Example The elements of the play that enforce that WilsonÃ¢â¬â¢s play is about African-American life than the universal man include; TroyÃ¢â¬â¢s inability to participate in professional baseball as a young man, and the fact that he had to consult their boss Mr. Rand to become a truck driver (Fences 40). Troy Maxson sets up the direction of the playÃ¢â¬â¢s plot in such a way that the theme of fatherhood and responsibility are depicted throughout the play. Events such as unfaithfulness in his marriage create a struggle for him as his wife takes care of another womanÃ¢â¬â¢s child but ends her relations with Troy. The rivalry between Troy and Cory is revealed when the father denies him the chance to play baseball professionally hence making the son move out of the house (Fences 57-60). The comment that surprised me in the interview was that when African Americans go back to Africa they are treated as white tourists and in the dictionary the blacks are regarded as violators of laws. This is interesting because in one land they are discriminated and in another they are celebrated and regarded as visitors. I felt that the interviewer does not get what Wilson was saying at the end of the interview. This is because he wonders why Wilson defends the blacks all the time yet one of his parents is white. What Wilson says relates to my experience in the world as I have witnessed some African-Americans striving to look for jobs and those in employment earning low incomes. WilsonÃ¢â¬â¢s play created a realistic set of characters and situations effectively as it displayed what happens in most African-American families where one of the relatives could be in prison, parents struggling to get money to pay their bills and their children discriminated in society because of their races. I would particularly relate to the scene where Cory is denied by the father a chance to play professional
