Concussions in football Essay Example for Free

Concussions in football Essay Injuries in professional sports are always occurring, but in football the risk of injury is much higher considering it is a contact sport. Although One of Americas most precious pastimes; American Football is the most dangerous sport because of the risk of concussions. Concussions in football have been a major concern though the years especially in recent years and the seriousness of this particular injury must be bought to the attention of not only the players, but to the media and professional leagues . Advancements in technology and health protocols have brought attention to the actual severity of concussions in football. Many NFL players that have had a concussion, or multiple concussions, not only struggle when they return to the field, but also struggle with normal aspects of their lives. The relevance of concussions has risen so far as of late, that former NFL players who previously suffered from concussions have gotten together to sue the NFL for improper information and protocol when they suffered their concussions. The concern of concussions has risen to a point where people have debated whether football should be banned altogether. The risk of concussions in football is very high compared to other sports. The constant contact and trauma that the head takes from being hit can sometimes lead to a concussion, but they are usually sustained through one powerful hit to the head. â€Å"The impact of one player running into another has almost twice the strength then one person running into a standing, or placed individual† (Onion). This would prove noteworthy for the kickoff or punt return aspect of football. During these situations the opposing teams are running full speed toward each other, and the ball carrier is usually the one who is at the most risk for concussion. The discussion of removing kickoffs and punts has been a major topic of discussion because of these facts. There are also different levels of concussions. â€Å"A minor concussion or grade one concussion may involve being dazed, head ringing, a minor headache, and a very brief loss of consciousness. A more severe concussion such as a grade 2 concussion may cause being blacked out, confusion, a pounding headache, and blurred vision. The most server concussion or grade 3 concussion may cause being blacked out, nausea or vomiting, loss of short term memory, and saying the same thing over and over†(Swierzewski). The most dangerous symptoms occur when a player is cleared to play before he has fully recovered from their concussion. When an athlete is cleared to play before he has fully recovered that is when death can occur. Retired players that have played professional football at some time in their life who sustained concussions have also had many problems in their retirement. One of these many retired players include former defensive lineman George Visger who frequently has memory loss or severe headaches. Visger said that he believes that he â€Å"accumulated close to hundreds if not thousands of concussions throughout his football playing career, some documented, some not† (Smith). Some problems that occur from concussions could end up being more life threatening then Visgers symptoms. â€Å"The suicides of former Chicago Bears Defensive end Dave Duerson and Owen Thomas, a University of Pennsylvania defensive end, have shown that the severity of concussions can psychologically destroy a person† (Compton). These symptoms that Visger, Duerson, and Thomas have or had experienced have happened to many other retired football players as well, which shows that this is very common among concussion recipients. Visger was also one of more than four thousand former NFL players who filed a seven hundred and seventy five million dollar lawsuit against the NFL for lack of information of concussions, and neglecting of the severity of concussions (Farrar). This settlement was reached and the money was granted to the players, but the fact is that these men must live with consequences that they received when they played the game of football. Not only is everyday life a struggle for these gentlemen, but the risks that they took can sometimes lead to their untimely death. Although most athletes are aware of concussions, not everyone is aware of the long lasting effects of them which are up to coaches and staff to explain. â€Å"The obligation of an employer to provide its employees with a safe workplace free from recognized hazards is well established. In the absence of specific standards for an industry, an employer is required under OSHAs general duty clause to provide its employees with a workplace free from recognized hazards which cause or are likely to cause death or serious physical harm†(Holmquist). In this case the employee is the athlete and the employers would be the football team’s staff and coaches. It is up to them to explain the long term consequences to these players, and enforce the safety protocol that must happen if they ever obtain a concussion. By doing this, the player is more informed of the risks of injury and the steps they have to take to either change the way they play, or simply don’t play the game at all. Equipment is also a major factor in dealing with concussions. The regulation helmet used in the NFL has gone through rigorous changes to keep concussions to a limit, but there is only so much you can do to prevent a concussion. â€Å"What helmets do not do well is significantly slow down the contents of the skull when the head is struck and moved suddenly† (Compton). The design of a helmet is made to prevent skull fractures not to prevent the fast impact of a hit to the head. Although technology will probably continue to improve the quality of helmets in football, the brute force of a hit to the head can probably never be covered up by any sort of helmet. The discussion of banning football due to the high risk of concussions has been a topic of debate also. Although it is ultimately the decision of someone to do what they want, they might not know the full consequences of what they’re getting into. It is important to educate athletes on the full on risks of concussions and how serious they really. If the overall topic of concussions can be explained to athletes, then football can be that much safer.

Mathematical Contributions of Blaise Pascal :: Biography Biographies Essays

Mathematical Contributions of Blaise Pascal Introduction Blaise Pascal was born on June 19, 1623 in Clermont Ferrand. His nationality was french. He died in 1662. He was credited for his imaginative and subtle work in geometry and other branches of mathematics. His work influenced later generations of theologians and philosophers, helping make mathematics what it is today. Blaise Pascal is considered part of the foundation of the very heart of mathematics. History At age 12 he mastered Euclid's Elements. In 1645, he invented and sold the first adding machine. His study of hydrostatics led to the invention of the syringe and hydraulic press. At age 16, he formulated the basic theorems of projective geometry. These theorems became known as Pascal's theorem. He proved that the level of mercury column in a barometer is determined by the increase or decrease in the surrounding atmospheric pressure. This discovery verified the hypothesis of the Italian physicist Evangelista Torricelli, concerning the effect of atmospheric pressure on the equilibrium of liquids. After publishing Essay pour les coniques (Essay on conic sections), Pascal temporarily abandoned the study of mathematics due to poor health. He lived in Paris for a while in a frivolous manner as a break. His interest in probability theory of the odds in gambling games lead him to discover the Theory of probability in conjunction with Pierre de Fermat. This theory dealt with the actuarial, mathematical, social statistics, and calculations used in today's modern theoretical physics. At the end of 1654, after several months of depression, Pascal had a life altering religious experience. He entered the Jansenist monastery in Port Royal. Here, he never published his own name again in his mathematical studies. He wrote a pseudonym to help in the struggle against the Jesuits for the defense of the Jansenist, Antoine Arnauld. In 1658, he broke with the Jansenists, and left the monastery. Pascal died on August 19, 1662 from cancer, at age 39. In his life, his most famous work was perhaps Pensees (thoughts). This was a set of deeply personal meditations in a somewhat fragmented form on human suffering and faith in God. Another famous work of his was called "Pascal's Wager." This expressed the conviction that belief in God is rational: If God does not exist, one stands to lose

Strategy on Tata Motors

The purchase of the Jaguar and Land Rover brands catapulted Tata into a different league, while also expanding its global footprint dramatically. Jaguar and Land Rover are highly sophisticated vehicles, well-engineered and superbly designed, selling to the upper middle-class motorists around the world. While Tata Motors has been running its UK subsidiary at an arm's length, it could eventually benefit from its engineering, design and marketing expertise. However, the benefits have not been yet spread to India, and Tata's range still relies on its pre-JLR cars.Prime among these is the world fs cheapest four-wheeler, the Nano urban subcompact. It was originally intended to sell for Rs1 lakh (Rs100,000), which at the time was equal to around US$2,000. The company had ambitious plans for the Nano, including exporting it to Western Europe and North America. In the event, the Nano ‘s price had to be increased, and it now starts at Rs1. 45 lakh with better-equipped and more sophistica ted models running up to twice that amount.Given the depreciation of the rupee over the past 18 months, the cheapest Nano can still be purchased for under US$2,400. At the time, it seemed that cheap vehicles were what India and other developing markets wanted. Some competitors scrambled to emulate the Nano, while prices of second-hand vehicles plunged. However, the strategy now seems to be a mistake. The car is still far more expensive than a motorcycle or a moped, while those who can afford a car are highly image-conscious. They don ‘t want to be seen in a car that is known to be the world ‘s cheapest – and looks the part.This problem has become more acute as India's car market has entered a period of stagnation, pushing down sales. So Tata is fine-tuning its Nano strategy. The new Nano will be more elegant, will have more desirable features and add-ons and will be given a higher price tag. Tata is planning to market it to a different group of motorists, includin g young urban professionals. A new group of highly educated, successful twenty-something has emerged in Indian cities, and they may find the Nano an attractive first vehicle.

Environmental Effects Of Urbanization On Shanghai And New...

A Comparison: environmental effects of urbanization in Shanghai and New York City Since the industrial revolution, many developed and developing countries have begun the process of urbanization to achieve faster development. The transformation from rural to urban brings the human beings convenience and wealth. However, in the past decade, many cities have met not only benefits but also challenges. Environmental problems continue to grow in those high-density areas. To investigate these problems and their influences, two cities, from a developed country and a developing country each, New York City (the U.S.A) and Shanghai (China) are chosen to compare. Both cities are economic centers in their own countries. New York City started its urbanization in the 19th century while Shanghai started in around 1980s. The process NYC has experienced, especially environmental problems, is a good example for Shanghai government to learn from when it continues its urbanization step in the future. Three problems are investigated: air pollution, water quality and soil contamination. These ones are significant in our lives as they can affect our organs and thus influences our health directly. Through urbanization, the most common view is the establishment of factories. Most of these factories are located in heavy industrial areas of the cities. It is easy to hypotheses that air quality has become worse in Shanghai since it started urbanization in the 1980s.
