Self Esteem in Athletes Compared to Non-Athletes Essays
Self Esteem in Athletes Compared to Non-Athletes The correlation of playing competitive sports at college level and self esteem are measured. Subjects were given the Barksdale self esteem questionnaire to fill out and levels of self esteem are measured by scores out of one hundred. The subjects are then separated into categories determined by gender and whether they played sports at the college level. The results indicated that the elite athletes have a higher self esteem than non athletes. The survey also revealed that women have a slightly higher self esteem than men. These findings agree with our hypothesis that athletes will have a higher level of self esteem than non athletes will. Self esteem is definedâ⬠¦show more contentâ⬠¦As well as looking at that research we also referred to the Encyclopaedia of human intelligence and an interesting article about exercise and cognitive functioning. The purpose of this research then is to find out of levels of self esteem differ in athletes and non athletes. The hypothesis drawn was that athletes would prove to have a higher overall average of self esteem when compared to non athletes. The null hypothesis is that their will be no difference between the two groups. Goals of this research are to satisfy some curiosity in the area and maybe dispel of some long reaching stereo types. Method It was decided that the goal would best be reached through a questionnaire given to people to fill out that would evaluate their self esteem. After going through many the Baarksdale self esteem evaluation no.69 , it was decided on as being the most thorough and the one most pertaining to he research. Some questions at the end were added asking for age, sex, and whether or not they play competitive sports. These questions were added so we could separate them onto the respective categories: athlete/non athlete. Our control group would be the group that does not play on a sports team. The athletes would be compared to them. The questionaries were handed out randomly.Show MoreRelatedEating Disorders Has Affected The Lives Of Many Athletes Around The World1546 Words à |à 7 PagesEating disorders have affected the lives of many athletes around the world.

Essay â⬠Bride and Prejudice Free Essays
People interact with and also with their surroundings. This impacts on their sense of belonging or their sense of isolation. We see this is William Shakespeareââ¬â¢s play ââ¬ËAs You Like Itââ¬â¢ and the Anglo-Indian genre movie, ââ¬ËBride and Prejudiceââ¬â¢ by Gurinder Chadha. We will write a custom essay sample on Essay ââ¬â Bride and Prejudice or any similar topic only for you Order Now The relationship between people and the interaction with place heavily impacts on the sense of belonging among the characters in the prescribed text. Rosalind and Celia are cousins who share a common understanding and identical values. Being from the same parental stock their social perception of life is similar. Their fathers being brothers, they share the same social economic circle. Their closeness is stressed when Celia paradoxically emphasises, ââ¬Å"you know my father hath no child but I, nor none is like to haveâ⬠. This shows Celia is prepared to forfeit the dutchy for her cousin Rosalind, which cements their friendship and helps them to improve their sense of bonding with each other. The ducal court and the lust for power sees Celiaââ¬â¢s father usurp the dukedom from his elder brother, Duke Senior, Rosalindââ¬â¢s father. This chaotic deed breaks the bond of unity and segregates Duke Senior, Rosalind, Celia, Orlando, Jacques and Adam. The two fathers are located in a contrasting environment. The court of Duke Fredrick is seen as a contrast to the forest od Arden. Duke Fredrickââ¬â¢s court seems to foster values of flattery, falsity and autocracy. These values create friction on the bond of belonging and unity. Where as the forest of Arden is an allusion of the garden of Eden. The interaction with this rustic setting acts as a whet stone to refine the disturbed banished crew of exiles. Duke Seniorââ¬â¢s syntactical expression, ââ¬Å"running brooksââ¬â¢Ã¢â¬ and ââ¬Å"sermon in stonesâ⬠shows the peace and serenity of the forest of Arden. This natural environment of forest of Arden also fosters friendship. Hardship also accompanies the calm serenity of this so-called paradise because the harsh, ââ¬Å"churlish chidingsâ⬠and ââ¬Å"bites and bolowsâ⬠of the weather fosters a sense of independence on each of the exiled members in the forest. Rosalindââ¬â¢s impersonating as Ganymede protects not only her virginity but also her cousin Celiaââ¬â¢s maidenhood. These good times and bad times and the will to succeed are essential qualities that assist the sense of belonging in the prescribed text. Love is another pervading factor in emotional belonging. The sisterly affection between Rosalind and Celia acts as a wedge that not only glues them together but also binds Orlando with Rosalind; Duke senior with his younger brother Duke Fredrick; Celia with Oliver and Phoebe with Silvius. Thus we see how Shakespeare portrays how belonging can be nurtured with love, understanding and a firm purpose of commitment for a common good. Shakespeare justifies the power of love and in the concept of belonging by making Rosalind metaphorically refer to love as madness, ââ¬Å"love is merely a madnessâ⬠¦that he whispers are in love tooâ⬠. By this quibble Rosalind tries to humorously convince Orlando that just as he is in love with her, she is also madly in love with him. This reciprocal interaction with each other helps to foster unity among all the characters in the play. Similarly Gurinder Chadhaââ¬â¢s romantic musical film, Bride and prejudice portrays the concept of belonging that is nurtured on account of interaction with people and places. The Bakshi Family has a strong sense of togetherness within the home and also the microscopic environment of their rural setting in Amritsar. The film in the opening scene uses mise en scene with the protagonist Lalita Bakshi serene in her environ. In the scene that follows we see The Bakshi Family, in their Indian accent, discuss marriage. The love and closeness of the sisters, Jaya, Maya and Lakhi establish their security, warmth and comfort within their home. This closeness and sacrifice is also displayed in the prescribed text where Rosalind and Celia make sacrifices for each other. Interaction with a place is presented where Lalita, the heroine, has to build an affinity not only with Amritsar in India but also with Will Darcyââ¬â¢s wealthy American family hotel in America. Her education al competence helps her easily integrate with the American way of life. In like manner even though Darcy felt out of place on his first visit to Amritsar in India, his love for Lalita made him adjust with the Indian culture and also with the Indian locale. The contrast of Darcyââ¬â¢s occidental attire in the early scenes is different in the concluding part of the film. The oriental drum beat played by Darcy himself and his Indian outfit piloted, by an elephant, shows how in belonging sacrifices need to be made. These sacrifices create a bond between the members who yearn for a common goal. In the case of Bride and Prejudice the love between Will Darcy and Lalita Bakshi cement a relationship between the Bakshi family and the Darcy family; so also in As You Like It the love between Celia and Oliver and Rosalind and Orlando foster a sense of belonging between the members of the ducal court and the members in The Forest of Arden. Thus establishing the fact that interaction between people and places heavily impacts on the sense of belonging. On analysing both texts we see, William Shakespeare and Gurinder Chadha uncover how a sense of belonging or isolation is created by the people we interact with, the environment in which we are and the love , understanding and concern we express for each other.

Maslahah Mursalah free essay sample
Historically, the notion of maslahah mursalah originated in the practice of the Companions. This is, of course, not to say that the Prophet did not rule in favour of maslahah, but merely to point out that as a principle of jurisprudence, maslahah mursalah does not apply to the rulings of the Sunnah. The main support for istislah as a proof and basis of legislation (tashri) comes from Imam Malik, who has given the following reasons in its favour: The Companions have validated it and have formulated the rules of Shariah on its basis. When the maslahah is compatible with the objectives of the Lawgiver (maqasid al-shari`) or falls within the genus or category of what the Lawgiver has expressly validated, it must be upheld. For neglecting it under such circumstances is tantamount to neglecting the objectives of the Lawgiver, which is to be avoided. Hence maslahah as such is a norm of the Shariah in its own right; it is by no means extraneous to the Shari`ah but an integral pair of it. We will write a custom essay sample on Maslahah Mursalah or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page When maslahah is of the genus of the approved masalih and is not upheld, the likely result would be to inflict hardship on the people, which must be prevented. Shatibi, I`tisam, II, 282-287; Abu Zahrah, Usul, p. 223. ] Conditions (Shurut) of Maslahah MursalahThe following conditions must be fulfilled in order to validate reliance on maslahah mursalah. The maslahah must be genuine (haqiqiyyah), as opposed to a specious maslahah (maslahah wahmiyyah), which is not a proper ground for legislation. The second condition is that the maslahah must be general (kulliyyah) in that it secures benefit, or prevents harm, to the people as a whole and not to a particular person or group of persons. The maslahah must not be in conflict with a principle or value which is upheld by the nass or ijma`.

Causes of the American Revolutionary War essays
Causes of the American Revolutionary War essays The American colonists were justified in waging war and breaking away from Britain because of unjust laws and a tyrannical king. All of these things outraged the colonists in different ways, leading them to unite together and rebel against Britain, hence leading to the Revolutionary War. First off, Parliament imposed many unjust laws. According to Document 2, the colonists believed that Britain had the right to impose laws to regulate trade, however, on the contrast, the introduction of the Stamp Act was pure to gain revenue. The Stamp Act particularly affected lawyers, merchants, and editors, as well as the general public. Document 5 reads "Parliament can 'of right make laws to bind us in all cases whatsoever.'" This can lead someone to argue that Parliament felt it had complete control over the colonies and that it could pass numerous laws to keep that control. For instance, once the Sons of Liberty used mob violence to force all stamp agents to resign and the Stamp Act was repealed, Parliament asserted its rights with the Declaratory Act. Document 5 also infers that the unfair laws and taxes imposed on the colonists were enforced by the "tyranny of irritated [British officials]." The colonists argued that they were unfairly being taxed without representation, th is being the first time that the colonies began to unite and rebel against the British government. Secondly, a cruel and intolerable king oppressed the colonists. Document 6 blames the King of England for the Battles of Lexington and Concord on April 19, 1775, and refers to him as "the hardened, sullen-tempered [King of England]." This document excerpted from Thomas Paine's pamphlet "Common Sense," convinced many Americans that independence was the only resolve to the conflicts between America and England. Accusations in Document 7 also suggest that the king had "a history of repeated injuries and usurpation," and that his overall character could describe a "tyrant"...

The Basic Guide to Integers on ACT Math
The Basic Guide to Integers on ACT Math SAT / ACT Prep Online Guides and Tips "Let x and y be integers such that...", "If y is a positive integer, what is...?" If you've taken a practice test or a real ACT before, these types of questions may look familiar to you. You've likely come across several questions on the ACT that mention the word "integer." And if you don't know what that word means, they will be difficult problems for you to solve. Questions involving integers are common, so it's important to have a solid grasp of what integers are as you continue in your ACT math study. But what are "integers" and how do they fit into the larger ACT math picture? This article will be your guide to basic integers for the ACT, what they are, how they change, and how you'll see them used on the test. For the more advanced integer conceptsincluding absolute values, exponents, roots, and morelook to our advanced guide to ACT integers. What is an Integer? An integer is a whole number. This means an integer is any number that is NOT expressed with a decimal or a fraction. Integers include all negative whole numbers, all positive whole numbers, and zero. Examples of Integers: -32, -2, 0, 17, 2,035 NOT integers: Ãâ¬, $2/3$, 0.478 Think of an integer as an object that cannot be divided into pieces. For example, you can't have half an egg in a basket. Positive and Negative Integers A number line is used to demonstrate how numbers relate to each other and to zero. All numbers to the right of zero are positive numbers. All numbers to the left of zero are negative numbers. Positive numbers get larger the farther they are from zero. 154 is larger than 12 because 154 is farther along the number line in a positive direction (to the right). Negative numbers get smaller the farther away they are from zero. -154 is SMALLER than -12 because -154 is a farther along the number line in a negative direction (to the left). And a positive number is always larger than any negative number. 1 is larger than -10,109 Because we don't have a reference for 0, we cannot say for sure whether A is positive or negative, which eliminates answers F, G, and K. We do know that any number to the left of another number will be less, so the answer must be H, A is less than B. The very opposite of a number line. Typical Integer Questions on the ACT Most ACT math integer questions are a combination of word problem and equation problem. The question will usually present you with an equation and tell you that you must use "integers" in place of a variable. You must know that an integer means a whole number (and that integers also include negative numbers and zero) to solve these problems. When xâⰠ0, there are two possible integer values for x such that y=x(1+x). What is a possible value for y? (A) âËâ30(B) âËâ1(C) 0(D) 15(E) 20 (We'll walk through how to solve this problem in the next section.) Sometimes youââ¬â¢ll have to answer more abstract questions about how integers relate to one another when you add, subtract, multiply and divide them. You don't need to find a numerical answer for these types of questions, but you must instead identify whether certain equations will be even or odd, positive or negative. For these types of questions, you can either guess and check how integers change in relation to one another by plugging in your own numbers and solving, or you can memorize the rules for how integers interact. How you do it is completely up to you and depends on how you learn and/or like to solve math problems. For example, in the charts below, you'll see that: aââ¬Å' positiveââ¬Å' number * aââ¬Å' positiveââ¬Å' number = aââ¬Å' positiveââ¬Å' number, each and every time. If you forget this rule (or simply don't want to learn it in the first place), you can always try it by saying 2 * 3 = 6. Because you can always find these results by plugging in your own numbers, these rules are categorized as ââ¬Å"good to know,â⬠but not ââ¬Å"necessary to know.â⬠negative * negative = positive -2 * -3 = 6 positive * positive = positive 2 * 3 = 6 negative * positive = negative -2 * 3 = -6 Another way to think of this is, ââ¬Å"When multiplying numbers, the result is always positive unless youââ¬â¢re multiplying a positive number and a negative number.â⬠odd * odd = odd 3 * 5 = 15 even * even = even 2 * 4 = 8 odd * even = even 3 * 4 = 12 Another way to think of this is, ââ¬Å"When multiplying numbers, the result is always even until multiplying an odd number and an odd number.â⬠odd +/- odd = even 5 + 7 = 12 even +/- even = even 10 - 6 = 4 odd +/- even = odd 5 + 6 = 11 Another way to think of this is, ââ¬Å"When adding or subtracting numbers, the result is always even unless adding or subtracting an odd number and an even number.â⬠With these understandings in mind, let us look again at the above ACT math problem. Choice A is incorrect, because b is an even integer. And we know that an even number * an odd number = an even number. Choice B is incorrect because a is an odd integer. And we know that an odd number + an odd number = an even number. Choice C is incorrect because a is an odd integer and b is an even integer. An even number + an odd number = an odd number. And an odd number * an even number (in this case 2) = an even number. Choice D is correct. Twice b will be even, because an even number * an even number = an even number. And the final result will be odd because an odd number (a) + an even number (2b) = an odd number. Choice E is incorrect. Twice an odd number (a) will be an even number, because an even number * an odd number = an even number. And an even number + an even number = an even number. So your final answer is D, a + 2b. You can see how you could also solve this by double-checking these rules by using your own numbers. If you assign an odd number to a and an even number to b, you can test out each option in about the same amount of time it would take you to go through your rules like this. So for this question, you could have said a was 5 and b was 6. Then option D would have looked like this: 5 + 2(6) = 17 Again, because you can figure out these kinds of questions using real numbers, these rules are classified as "good to know," not "necessary to know." If you follow the right steps, solving an integer problem is often much easier than it appears. Steps to Solving an ACT Math Integer Problem #1: Identify if the problem is, in fact, an integer problem. If you must use integers to solve a problem, the ACT will explicitly use the word "integer" in the question so that you don't waste your time and effort looking for decimal or fraction solutions. For example, questions may begin with: "x is a positive integer such that...", "For all negative integers...", or "How many integers give the solution to...?" For any problem that doesnââ¬â¢t specify that the variables (or the solution) are ââ¬Å"integers," your answer or the variables can be in decimals or fractions. So let's look again at the problem from earlier: When x âⰠ0, there are two possible integer values for x such that y = x(1+x). What is a possible value for y? (A) âËâ30(B) âËâ1(C) 0(D) 15(E) 20 We are told that x âⰠ0, so we know that our y cannot be 0. Why not? Because the only integer values that can give you y = 0 are x = 0 and x = âËâ1 because 0(1+0) = 0 and (âËâ1)(1+(âËâ1)) = 0. BUT we were told that x âⰠ0. So y can not equal 0 either, as the question told us that there were TWO integer values for x, neither of which is 0. This means we can cross off C from the answer choices. We can also cross off A and B. Why? Because there is no possible way to have x(1+x) equal a negative. Even when x is negative, we would distribute the problem to look like: y = (1x) + (x * x) We know that a negative * a positive = a negative, so 1x would be negative if x were negative. BUT a positive * a positive = a positive. And a negative * a negative = a positive. So x * x would be positive, whether x was positive or negative. And adding the original negative value for x will not be a large enough number to take away from the positive square and make the final answer a negative. For example, we already saw that: x =âËâ1 makes our y zero. x =âËâ2 gives us âËâ2(1+âËâ2) = y = 2. x =âËâ3 gives us âËâ3(1+âËâ3) = y = 6, etc. So we are left with answer choices D and E. Now how could we get 15 with x(1+x)? We know x must not be very large to get y = 15, so let's test a few small numbers for x. If x = 2, then x(1+x) = 2(1+2) = 6. This means x = 2 is too small. If x = 3, then x(1+x) = 3(1+3) = 12. So x = 3 is too small. If x = 4, then x(1+x) = 4(1+4) = 20. This means there is no positive integer value that could give us 15. But we did manage to get y = 20, so answer choice E is looking pretty good! Now we can tell that if we kept going higher with x, the y value would keep getting larger (x = 5 would give us y = 30, etc.). This means we probably need a negative integer to give us our second value for x. So let's try to get y = 20 with a negative value for x this time. We already saw above that x = âËâ2 gave us y = 2, and x = âËâ3 gave us y = 6. So let's try some more negative values for x. If x = âËâ4, then x(1+x) = âËâ4(1+âËâ4) = 12 If x = âËâ5, then x(1+x) = âËâ5(1+âËâ5) = 20 We were able to get y = 20 with both x = 4 and x = âËâ5 So our final answer is E, y = 20 #2: If the problem asks you to identify equations that are always true, test out multiple different kinds of integers. If the question asks you to identify whether certain equations or inequalities are true for ALL integers, the equation must work equally with 10 as with 0 and -5. A good rule of thumb is to try -1, 0, and 1 with variable questions like these. These numbers often have special properties that make or break conditions. I'll explain what that means with a practice example. If x is an integer, which of the following equations MUST be true? I. $x^3 âⰠ¥ (-x)^3$ II. ${x^3}/x âⰠ¥ {x^2}/x$ III. $x(x + 1) âⰠ¤ -x + x^3$ (A) I only(B) II only(C) III only(D) I and III only(E) I, II, and III For questions like these, we should test out our sample numbers, as it can get confusing to use our rules of integer behaviors with complex problems such as these. So for option I, let use our test numbers of -1, 0, and 1. $âËâ1^3= (âËâ1)(âËâ1)(âËâ1) = âËâ1$ $(âËââËâ1)^3 = $1^3 = (1)(1)(1) = 1$ -1 is NOT greater than +1. This automatically eliminates option I. And by eliminating option I, we can eliminate answer choices A, D, and E right away. Now let's look at choice II with our same test numbers. ${(-1)^3}/{-1} = {(-1)(-1)(-1)}/{-1} = {-1}/{-1} = 1$ ${(-1)^2}/{-1} = {(-1)(-1)}/{-1} = 1/{-1} = -1$ 1 -1 This means that option II works so far when we use a negative number. So let's try it with our positive number, 1. ${1^3}/1 = {(1)(1)(1)}/1 = 1/1 = 1$ ${1^2}/1 = {(1)(1)}/1 = 1/1 = 1$ 1 = 1. So option II still works. Lastly, we should test if the equation still works with 0. ${0^3}/0 = 0$ $0^2/0 = 0$ Option II works for all answer choices, so our final answer is B, II only. Because we know that option I doesn't work, we have eliminated all other answer choices. But if you want to make absolutely sure you didn't make a mistake somewhere, you can test out option III as well. âËâ1(âËâ1+1) = 0 $âËâ(âËâ1)+(âËâ1)^3 = 1+(âËâ1)(âËâ1)(âËâ1) = 1+âËâ1 = 0$ 0 = 0 The two are equal, which means that option III works so far. Now let's try it with 1. 1(1+1) = 2 $âËâ1+1^3 = âËâ1+(1)(1)(1) = âËâ1+1 = 0$ 2 0 When we used a positive number, the equation was incorrect. This means that answer choice C is eliminated and our choice of B has been confirmed to be the only correct answer. #3: If the problem asks you to find the answer to long calculations, use your rules that you learned above or test it out with smaller numbers. a, b, c, d, e, f are odd integers such that a b c d e f. Which statement(s) must be true? I. abcdef is odd II. a + b + c + d + e + f is odd III. a(b + c + d + e + f) is odd (A) I only(B) II only(C) III only(D) I and III only(E) I, II, and III Now you can approach this problem in one of two ways: by using your number rules or by using your own numbers. First, let's use our number rules to test option I. We know that each letter represents an odd integer and that the product of an odd number and another odd number is an odd number. Because an odd * an odd will always be odd, we know that option I is true. This means we can also eliminate answer choices B and C. Now let's look at option II. We know that an odd number + an odd number = an even number. We also know that an even number + an even number = an even number. So if we split a + b + c + d + e + f into pairs of numbers, we'll have: (a + b) + (c + d) + (e + f) We know that each pair of numbers will have an even sum, so we're left with: an even number + an even number + an even number, which will give us an even final result. So option II is incorrect. This means we can eliminate answer choice E. Finally, let's look at option III. As we saw before, when we have six odd numbers (in other words, an even number of odd numbers), the sum will be even. Now, our parenthesis holds five (an odd number) of odd numbers, and an even number + an odd number = an odd number. So we know the number in the parenthesis will be odd. We also know that an odd number (a) * an odd number (the sum of b, c, d, e, f) = an odd number. So option III is correct. This means that our final answer is D, I and III only. The other way you could solve this problem would be to test out these rules with small numbers and extrapolate to find the larger answer. In other words, use small numbers in place of the variables. So for option I, if you didn't know an odd * an odd = an odd, you could replace a and b with the numbers 5 and 3. 5*3=15, so you know that an odd * an odd = an odd number, no matter how many times you multiply it. So option I is correct. For option II, again test it out with smaller numbers. 7+5=12, and 7+5+3=15. So you know that adding odd numbers an even number of times gets you an even answer and adding an odd number of times gets you an odd answer. There are six odd numbers, so the final answer must be even. Option II is incorrect. Taking what you learned by testing option II, you know that adding odd numbers an even number of times gets you an odd answer. And, taking what you learned from testing option I, you know that an odd number * an odd number = an odd number. This means your final answer must be odd, so option III is correct. This means the final answer is D, I and III only. Whoo! There are many ways to solve integer problems and whichever way works for you is perfect. The Take-Aways In order to solve both the basic and advanced ACT integer questions, you must first understand what an integer is. Only then can you build up your integer knowledge to the more advanced concepts. But simply knowing that an integer is a whole number (and that 0 and negative numbers are also integers), will allow you to solve some of the more basic questions about how to plug integers into equations and how integers relate to one another. For the more advanced integer concepts, including absolute values, exponents, etc., be sure to check out our advanced guide to ACT integers. What's Next? Now that youââ¬â¢ve learned about what integers are, you may want to check out the advanced guide to ACT integers where we will go through absolute values, prime numbers, and exponents (among other concepts).
