Concussions Research

Every year â€Å"hundred of thousands college and high school student athletes receive sport related concussions† (Meadows 107-108). Not only do the athletes who play the hard hitting contact sports such as football and hockey receive concussions, the basketball players and soccer players receive them as well. Even though most of the concussions received were mild or grade 1 concussion â€Å"athletes still receive severe symptoms due to being able to participate too soon† (Solomos 2435-2436). In order to protect college and high school athletes, colleges and high schools have to take concussions more seriously and adopt new safety guidelines for concussions injuries. It is necessary for athletes to know the dangers of concussions. A concussion happen when an â€Å"impact to the head makes the brain move around in the skull† (Vance A36-A38). Due to the force of the impact concussions can cause minor or major head trauma. There are three different stages or grades 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†(Cunha 581-585). The most dangerous symptoms occur when a player is cleared to play before he/she has fully recovered from their concussion. When an athlete is cleared to play before he/she has fully recovered that is when death can occur. Not only are concussions common in college sports but concussions are more common and more dangerous in high school sports. In an experiment done by American Family Physician writer Richard Sadovsky found out many interesting facts about college and high school athletes who suffer from concussions. â€Å"According to Sadovsky college athletes had a higher rate of loss of consciousness than high school athletes, but at 24 hours after injury, longer memory impairment was higher in high school athletes†(171-172). Also Sadovsky found out that â€Å"post concussion symptoms lasted longer in high school athletes then in college athletes† (171-172). Sadovsky also concluded â€Å"that neuropsychological recovery was slower in high school athletes† (171-172). To explain the difference between college and high school, the author stated that there is â€Å"more prolonged cerebral swelling in less mature brains† (Sadovsky 171-172). Another reason why high school athletes have more dangerous symptoms is because not all athletes in high school are well trained or in shape for the sport they play. Male athletes aren’t they only ones who have to worry about concussions, according to Time â€Å"female athletes suffer from more concussions than male athletes do† (Gregory 69-70). Even though contact sports such as football and hockey have the highest rates of concussions studies show that female athletes actually suffer from concussions more then males do in sports that both males and females can play. One reason is that female athletes are more common to report a concussions then male athletes. But there are â€Å"anatomical reasons that explain why females are more likely to have a concussion diagnosed† (Gregory 69-70). The top reason why females receive more concussions then males is because research proves that men’s necks are 20% larger and 50% stronger then women’s necks†(Gregory 69-70). This is important because with bigger stronger neck muscles the athlete can balance the head during impact and lower the chances of brain being moved around during a collision. Another reason why girls suffer more concussions is because of the way they play. Kevin Guskiewicz, director of the Sports Medicine Research Laboratory at the University of North Carolina, â€Å"has found that female athletes are more likely than male athletes to land on the floor or field with their knees locked† (Gregory 69-70). This is important because with their knees lock they have less balance, and with less balance increases there chances of hitting the ground or another player.

Acceptance Or Rejection Of The Null Hypothesis Economics Essay

Acceptance Or Rejection Of The Null Hypothesis Economics Essay The appropriate value of t is 2.100. Since we are concerned whether b (the slope of original regression line) is significantly different fro B (the hypothesized slope of population regression), this is a two tailed test, and the critical values are  ±2.100. The standardized regression coefficient is 0.063, which is inside the acceptance region for our hypothesis test. Therefore, we accept null hypothesis that B is equal to 0.01. Step 6: Interpretation of the Result There is not enough difference between b and 0.01 for us to conclude that that B has changed from its historical value. Because of this, we feel that a one hundred percent increase in inflation would increase the poverty headcount by around 0.01%, as it has in the past. 2. Inflation and Ginni Coefficient The slope for the regression line that shows a relationship between inflation and gini coefficient is 0.5956. This means that a 100% increase in inflation would result in 0.5956% increase in gini coefficient. Now we wou ld perform the same hypothesis testing procedure to determine the authenticity of slope and whether the slope justifies the relationship between inflation and gini coefficient. Step 1: State the Null and the Alternative Hypothesis Let B denotes the hypothesized slope of actual regression line, the value of the actual slope of regression line is b = 0.5956. The first step is to find some value for B to compare with b= 0.5956. Suppose that over an extended past period of time, the slope of the relationship between inflation and gini coefficient was 0.5. To test whether this is still the case, we could define the hypothesis as: H0: B= 0.50 (Null hypothesis) H1: B à ¢Ã¢â‚¬ °Ã‚   0.50 (Alternative hypothesis) Step 2: Decide on Significance Level and Degree of Freedom Significance level ÃŽÂ ± = 0.05 and Degree of freedom (df) = n-2 = 19 – 2 = 17 Step 3: Find out Standard Error of b Where Sb = standard error of the regression coefficient Se = standard error of estimate Xi = valu es of the independent variable X-Bar = mean of the values of the independent variable n = number of the data points Year X Y X – X-Bar (X-X-Bar)2 Y2 XY 1963-64 4.19 38.6 -2.607368 6.79837008 1489.96 161.734 1966-67 8.58 35.5 1.7826316 3.17777535 1260.25 304.59 1968-69 1.58 33.6 -5.217368 27.2209332 1128.96 53.088 1969-70 4.12 33.6 -2.677368 7.16830166 1128.96 138.432 1970-71 5.71 33 -1.087368 1.18237008 1089 188.43 1971-72 4.69 34.5 -2.107368 4.44100166 1190.25 161.805 1979-80 8.33 37.3 1.5326316 2.34895956 1391.29 310.709 1984-85 5.67 36.9 -1.127368 1.27095956 1361.61 209.223 1985-86 4.35 35.5 -2.447368 5.98961219 1260.25 154.425 1986-87 3.6 34.6 -3.197368 10.2231648 1197.16 124.56 1987-88 6.29 34.8 -0.507368 0.25742271 1211.04 218.892 1990-91 12.66 40.7 5.8626316 34.370449 1656.49 515.262 1992-93 9.83 41 3.0326316 9.19685429 1681 403.03 1993-94 11.27 40 4.4726316 20.0044332 1600 450.8 1996-97 11.8 40 5.0026316 25.0263227 1600 472 1998-99 5.74 41 -1.057368 1.11802798 1681 23 5.34 2001-02 3.54 27.52 -3.257368 10.610449 757.3504 97.4208 2004-05 9.28 29.76 2.4826316 6.16345956 885.6576 276.1728 2005-06 7.92 30.18 1.1226316 1.26030166 910.8324 239.0256 Summation 129.15 678.06 0 177.829168 24481.06 4714.9392 X-Bar = 6.79 Y-Bar = 35.68 Se = 3.59 By putting Se and Summation (X-X-Bar) 2 in Sb, we have Sb = 0.269 Step 4: Find the Standardized Value of b t = b – BH0/Sb Where b = slope of fitted regression BH0 = actual hypothesized slope Sb = standard error of the regression coefficient By putting the values of the above in t, we have t = 0.355 Step 5: Conclusion on Acceptance or Rejection of the Null Hypothesis The appropriate value of t is 2.10. Since we are concerned whether b (the slope of original regression line) is significantly different from B (the hypothesized slope of population regression), this is a two tailed test, and the critical values are  ±2.10. The standardized regression coefficient is 0.355, which is inside the acceptance region for our hypothesis test. Therefore, we accept null hypothesis that B is equal to 0.5 Step 6: Interpretation of the Result There is not enough difference between b and 0.50 for us to conclude that that B has changed from its historical value. Because of this, we feel that a one hundred percent increase in inflation would result in an increase of 0.50% in gini coefficient, as it has in the past.

Differences and Similarities between Christianity and Islam Essay

Differences and Similarities between Christianity and Islam - Essay Example As the son of God, Jesus is an integral part of God. Christianity is based on the idea that God has revealed Himself through Jesus Christ. Every Christian should live in accordance with the ten Christian commandments that forbid people to kill, lie, steal, etc. These laws are designed to help a person to live a life that is pleasing to God. In this respect, faith in Jesus Christ as their personal savior is a central element of Christianity. The theme of salvation presented in Christianity is inextricably linked with the idea of Jesus Christ and his role in the whole of humanity. According to the Christian view, Christ is the Messiah who came to save the world. Faith in Jesus Christ and His atoning sacrifice is the central element of Christianity. A Christian is a person who believes in the death and resurrection of Christ who came into this world to save all humankind from sinfulness. In other words, Christianity is not conceivable without faith in Jesus Christ and His extremely impo rtant role for all of humanity. Faith in Jesus Christ as the Son of God is the opportunity for eternal life after death. Through the figure of Jesus, the concept of death receives the original interpretation.Christianity does not accept death as an end, rather, death is seen as the beginning of a new life, while life on earth serves as a preparation for it (Houben, n.d.). The first humans (Adam and Eve) were created by God for eternity but they ate the forbidden fruit and became mortal. Man has lost the right to live an eternal life on earth.

The understanding of modern urban life Essay Example | Topics and Well Written Essays - 1250 words

The understanding of modern urban life - Essay Example Simmel underlined that "the city conspires to erase difference by assaulting the individual with an overwhelming and never-ending stream of visual stimuli" (Byram, 2002) and also that our society consists of individual interactions and this defines its identity: "While there is no perception of society until individuals begin to interact, once formed by the interaction of individuals, the society affects the individuals as an outside force" (Crow Ch., et al., 2000). Benjamin considered the modern urban experience through the development of technologies and supported communications development; he was positive about new technologies, emphasizing their liberating influences. He was positive towards such technologies as film and photography: "New media technologies such as phonographs, epic theatre, and especially film and photography, not only destroy art's 'aura' but demystifies the process of creating art, making available radical new access and roles for art in mass culture" (Bicket, 2001). Simmel and Benjamin both underlined the importance of technological development and its influence on art, culture and our understanding of social environment. Simmel's views tend towards the negative influence of urban life on individuals, while Benjamin is more positively inclined tof technological and cultural aspects of modern and post-modern urban society. _______________________________________ Link both essays in together and edit from 1100 to 600 words ie what is contained between the line above and the line at the end A utopia is an imaginary place, situated in a particular time and space, that is socially, morally, and politically ideal, and a dystopia is its exact opposite. Ideologies are as transient as fashions and can be subjective, as they are relative to the perspective employed. Hitler and his comrades had a utopia in mind when they sought to create the Thousand Year Reichbut Jews, Gypsies, homosexuals, and other victims of his vision would beg to differ (Tartar, 2004). Human rationality implies, for enlightened thinkers, an attempt to know and understand the natural world. As Norman Hampson writes, "human reason, operating by means of careful observation and checking its conclusions by further observation or experiment, could for the first time in the history of man reveal the mechanism of the natural world. "The extreme rationalism of Descartes, its traditional alternative and empiricist aspects and the debate between them, constitute the most influential part of Enlightenment in the nineteenth century. The Enlightened thinkers were generally confident that they could use rational principles to solve social interaction problems and this belief led to the Enlightened faith in social progress and the culmination of the Enlightenment ideals in a utopian society. Nietzsche opposed this Enlightened faith in progress as nave;but being unable to elude it, itwas the Enlightenment's utopianism that accompanied him through his most radical critiques (Call, 1995). A second theme involves the contradictions that necessarily exist between communality and individuality. Human consciousness is passive in accepting ideology, doctrine, orthodoxy and mass thinking and often sees reality in terms of the liturgy of certain

Is Childhood Discipline Effective Research Paper

Is Childhood Discipline Effective - Research Paper Example The essay would hereby initially trace the historical background of using corporal punishment, particularly smacking, as a tool for childhood discipline. In addition, the discourse would present a general overview of different positions or contentions on the issue of smacking as the most effective technique for childhood discipline. Finally, the concluding portion would highlight the crucial points discussed and present a speculation and recommendation on the most effective tool for childhood discipline in the future. Relevant History and Background The roots of corporal punishment could be traced from the earliest published article in a periodical, the San Francisco Call, dated March 23, 1893 entitled â€Å"Slap or Spank?: School Punishment Query in Alameda† where the School Board of Alameda supposedly sought to determine the manner by which parents would agree and stipulate the kind of chastisement to be used to discipline the children (corpun.com 1). At that time, the conte nts of the article generated different reactions and responses from school administrators, teacher and parents; with the final recommendation that â€Å"the general verdict of all those seen is to the effect that the spanking process is far superior to the regulation strap method, but all concurred in saying that the best way of all in such matters was to leave it entirely with the teachers, who should be kept within bounds regarding the severity of the punishment inflicted by rules laid down by the Board of Education† (corpun.com 1). Suffice it to say that even at the earliest published article on corporal punishment through spanking or smacking, the issue was elicited diverse and conflicting arguments. Some parents averred that they do not want their children to be spanked at all. Other parents support smacking on prescribed areas of the body, but never on the face. And still, surprisingly, one parent remarked that â€Å"’taken across the knee and spanked, by all me ans. That's the old way, and I have found it very efficient.’ And the obedience of the little ones clustered about her was good evidence of the truth of the statement† (corpun.com 1). These diverse reactions have evolved through centuries and until contemporary times, smacking continues to be a controversial issue. In current times, Gershoff and Larzelere disclosed that, â€Å"corporal punishment remains a widely used discipline technique in most American families, but it has also been a subject of controversy within the child development and psychological communities† (par. 1). The controversial nature is clearly depicted from the contradictory arguments advocated by parents, to wit: â€Å"The consultation document issued this month by the Department of Health on the physical punishment of children states clearly that ‘many parents would welcome support in learning effective measures of disciplining their child which do not involve physical punishmentâ₠¬â„¢ while adding that ‘there may still be occasions when parents †¦ may consider it appropriate to discipline a child through physical punishment’† (Waterston 261). In this regard, parents, social workers, health professionals and policymakers all provide different perspectives on the subject of corporal punishme

Reflecting upon the different models of the criminal justice system we Essay

Reflecting upon the different models of the criminal justice system we have studied, critically assess which you would most like - Essay Example Later on, the Judicature Act of 1873 was passed and the Criminal Appeal Act of 1907. Due process model According to Sanders, Young and Burton the English criminal system just like the American one, emphasizes on adversarial procedures and due process safeguards. The relevance of the due process in the English law is advised by the fact witnesses could be biased or the police force may interfere with the whole process. By insisting on a formal adjudicative process, the accused are able to get justice and beside, the entire process prevents the miscarriage of justice as an end to itself. In addition the due process discourages the law enforcement agencies from abusing power and breaking rules, while encouraging the primacy of the individual citizen. The role of the police in the criminal justice system is very constrained. As Wells and Quick (2010) observe in Wales and England, police can go as far taking an inquisitorial role but cannot force citizens to produce testimony against thei r will. The due process starts once an adversarial relationship has been formed or after becomes a suspect. In all fairness once can see that the role of the police is very limited in English and Wales criminal system. ... k (2010) the due process model as practiced in England and Wales, involves the use of procedural and evidentiary rules in order to avoid to prevent miscarriages of justice to the accused. Wells and Quick (2010) liken the due process model to an assembly line or an obstacle course designed to prevent the accused from progressing through the criminal process. The need for incorporation of the due process in the English and Wales criminal system is characterized by the elements of miscarriage of justice and observance of human rights. Another core element of the system is presumption of innocence doctrine, which is prescribed to by many other judicial systems all over the world. Presumption of innocence doctrine This is a core tenet in the criminal justice system, and is equally appreciated in the European Convention on Human Rights. The presumption of the innocence doctrine further suggests that the onus lies on the prosecution to prove the defendant’s guilt beyond reasonable do ubt. According to Wells and Quick (2010) by forcing the prosecution to prove its case against the accused in an adjudicative context, the accused acquires an enhanced opportunity to secure a favourable outcome. Shift from the due process system to the control system However, in the face of the increasing terrorist activities, and transnational crimes, the English government is under increasing pressure to adopt the crime control approach. At the same time, the English system is under pressure to initiate an appropriate legal framework to support the law enforcement agencies to control the levels of crime being experienced. The crime control model as suggested by Sanders, Young and Burton (2010) is based on the proposition that the repression of the criminal conduct is the main role of the

Capitalism Essay Example | Topics and Well Written Essays - 250 words - 2

Capitalism - Essay Example The fourteen century crisis leads to emergence of modern capitalism. Land ownership and agricultural production gave rise to conflicts. The arrangements of manorial hinder the development of capitalism. This was when lords force serfs to produce which hinder them from getting interests through technological innovations. The serfs could only produce what was enough for their families. Expansion of power and wealth by lords led to conspicuous consumption. The crisis in the century was through bad weather, productivity in agriculture and limitations on technology. There was division of classes due to rise of relationships which were contractual between serfs and lords. Feudalism laid foundations necessary for mechanistic development. Exploration also facilitates the development of capitalism. The rise of competition led to creation of the new model. It led to winning and losing. Feudalism which led to mechanistic led to ownership of corporation and private sectors. Decisions of private sectors, prices of different commodities, goods production and distribution characterize investments, which led to free markets (Heilbroner et al, 2011). Roman Empire introduces merchant capitalisms which were advanced. This proceeds to development of Islamic capitalism. Industrial capitalism, revolutions and division of labor are some of the factors that led to creation of new model. There are many similarities between Newton and Adam Smith. For example, Adam Smith identified didactical mode which he termed as Newtonian method. Smith helped in discovering general laws of economics while Newton discovered natural laws of motion. John Millar declared Smith as Newton’s political economy. Both contributed to the project of social cohesion and balance. According to Newton, simplicity pleases nature but focuses on economy which was embarrass by Smith. Ricardo and Malthus are pessimistic about the future of capitalism. Malthus from his theory fail to anticipate production
