Child Responsibilities Essay Example for Free

Child Responsibilities Essay Many parents may be very strict on their kids when it comes to doing things like playing with fire, using power tools, having a job, or even owning a pocket knife, but I on the other hand, disagree. Although I understand that it’s very dangerous for kids to be handling such things, it also builds their character. You wouldn’t just allow any kid to be in charge of such thing, they must have maturity and responsibility up to a certain point to be able to be trusted in these situations. A speech titled â€Å"5 Dangerous Things you should let your kid do† by Gever Tulley on TED.com talks about kids who are allowed and even encouraged to do things most parents would never dare to let their kids be involved in. Tulley discusses how kids who participate in these activities build strong character. It’s good for kids to be in these kinds of environments as long as they already have responsibility up to a certain level. An issue similar to this that is thrown around in politic and economic discussions now days is child labor. Should we allow kids to have jobs? Should families who are economically struggling allow their kids to work in order to bring in enough food and necessities to the family? I don’t see a problem in child labor. Like Tulley, I agree with these ideas and think they build better personalities and make a child more understanding. Although, I do not think that a family should be able to force a kid to work, it’s also important to a kid’s childhood that they get a chance to be a kid, and not have to worry about work. The earlier a person starts working, the bigger chance they have to be successful in life. I can understand why some parent’s wouldn’t be willing to let their kids be in such environments, these environments can be very unsafe sometimes. A kid could have the possibility of cutting a finger off, or doing something that they would have to live with for the rest of their lives, but with adult supervision this is less likely to happen. Although UNICEF has stated that children are more likely to get hurt then adults because they have yet to learn what not to do, we have to understand that getting hurt can happen in any activity that a person participates in, that’s just part of life.

Rewritten Pyramus and Thisbe Myth :: essays research papers

Pyramus was the cute boy next door, and Thisbe the prettiest girl in the entire neighborhood. They lived right next door to each other. Their parents were in a dispute over rent money; Thisbe’s father was the manager of the apartments and Pyramus’s parents had been late on their payments for a few months now. The kids were not allowed to talk or to see each other. One thing, however, they could not forbid- their young and carefree love that pound in each others hearts. They conversed by signs and glances, and the fire burned more intensely for being covered up. In the wall that parted the two apartments there was a crack, caused by the buildings old structure. No one had observed it before, but the lovers discovered it. What love can discover. As they stood, Pyramus on one side, Thisbe on the other, they would whisper to each other innocent non-sense. "Damn this freaking wall," they said, "Why do you keep us apart?† Such words they uttered on different sides of the wall; and when the night came and they must say goodnight, they would tell the other of how they are kissing the wall and imagining it was other. Next morning, when the sun had resin above the tallest skyscraper, and the city filled with busy noise and smog, they unveiled their plan to see each other. They had agreed to sneak out at night, they would wait till the routine police car had passed their block, and then each would run and meet at the old winery and wait till the other arrived. All was agreed on, and they waited impatiently for the sun to go down b eneath the buildings and night to rise up from them. Then cautiously Thisbe opened her back window- unsuspected by her parents, put a white scarf around her, waited for the police car to pass and escaped. As she sat alone in the dim light under one of the old street lights, she saw a drunk old man approaching her. With a thirst in his eyes Thisbe fled the sight, and sought refuge in the back alleys of the streets. As she fled she dropped her scarf. The drunken old man was hurt and was going to ask Thisbe for some help but just found a scarf on the ground and wiped his wound with it. Pyramus, late only because he had stopped at a local gas station to get some snacks for his dear love, finally arrived at the old winery.

Convexity and Nonsatiation

Checking the convexity and nonsatiation assumptions EC201 LSE Margaret Bray October 25, 2009 1 Nonsatiation 1. 1 1. 1. 1 The simple story De? nition and conditions for nonsatiation Informally nonsatiation means that â€Å"more is better†. This is not a precise statement, and it is possible to work with a number of di? erent de? nitions. For EC201 †¢ Nonsatiation means that utility can be increased by increasing consumption of one or both goods. If the utility function is di? erentiable you should test for nonsatiation by ? nding the partial derivatives of the utility function. 1. 1. 2Example: testing for convexity with a Cobb-Douglas utility function A Cobb-Douglas utility function has the form u(x1 , x2 ) = xa xb where a > 0 and b > 0. Here u(x1 , x2 ) = 12 2/5 3/5 x1 x2 . Assuming that x1 > 0 and x2 > 0 the partial derivatives are ? u ?x1 ?u ?x2 = = 2 ? 3/5 3/5 x2 > 0 x 51 3 2/5 ? 2/5 > 0. xx 51 2 (1) (2) You should note that because the partial deriva tives are both strictly1 positive utility is a strictly2 increasing function of both x1 and x2 when x1 > 0 and x2 > 0 so nonsatiation is satis? ed. 1. 1. 3 Implications of nonsatiation 1.If utility is strictly increasing in both goods then the indi? erence curve is downward sloping because if x1 is increased holding x2 constant then utility is increased, so it is necessary to reduce x2 to get back to the original indi? erence curve. 2. If utility is strictly increasing in both goods then a consumer that maximizes utility subject to the budget constraint and nonnegativity constraints will choose a bundle of goods which satis? es the budget constraint as an equality so p1 x1 + p2 x2 = m, because if p1 x1 + p2 x2 < m it is possible to increase utility by increasing x1 and x2 whilst still satisfying the budget constraint. A number is strictly positive if it is greater than 0. function is strictly increasing in x1 if when x0 > x1 and x2 is held constant at x2 then u x0 , x2 & gt; u (x1 , x2 ). 1 1 The important point here is that the inequality > is strict. 2A 1 1. 1. 4 Nonsatiation with perfect complements utility A utility function of the form u (x1 , x2 ) = min (a1 x1 , a2 x2 ) is called a perfect complements utility function, but the partial derivative argument does not work because the partial derivatives do not exist at a point where a1 x1 = a2 x2 which is where the solution to the consumer’s utility maximizing problem always lie.This is discussed in consumer theory worked example 6 1. 2 1. 2. 1 Nonsatiation: beyond EC201 Complications with the Cobb-Douglas utility function A really detailed discussion of nonsatiation with Cobb-Douglas utility would note that the partial derivative argument does not work at points where the partial derivatives do not exist. The partial ? u derivative does not exist if x1 = 0 because the formula requires dividing by 0. Similarly the ? x1 ?u formula for requires dividing by 0 if x2 = 0 so the function does not have a partial derivative with ? x2 respect to x2 when x2 = 0.However observe that if x1 = 0 or x2 = 0 then u(x1 , x2 ) = 0, whereas if x1 > 0 and x2 > 0 then u(x1 , x2 ) > 0 so if one or both x1 and x2 is zero then increasing both x1 and x2 always increases utility. Thus nonsatiation holds for all values of x1 and x2 with x1 ? 0 and x2 ? 0. 1. 2. 2 More general formulations ?u ?u > 0 and > 0 implies nonsatiation. However these conditions can be ?x1 ?x2 weakened considerably without losing the implication that the consumer maximizes utility by choosing a point on the budget line which is what really matters.For example if utility is increasing in good 1 but decreasing in good 2 so good 2 is in fact a â€Å"bad† the consumer maximizes utility by spending all income on good 1 and nothing on good 2. The condition that 2 2. 1 2. 1. 1 Convexity and concavity Concepts Convex sets A set is convex if the straight line joining any two points in the set lies entirely within the set. Figure 1 illustrates convex and non-convex sets. 2. 1. 2 Convex functions A function is convex if the straight line joining any two points on the graph of the function lies entirely on or above the graph as illustrated in ? gure 2.Another way of looking at convex functions is that they are functions for which the set of points lying above the graph is convex. Figure 2 suggests that if the ? rst derivative of a function does not decrease anywhere then the function is convex. This suggestion is correct. If the function has a second derivative that is positive or zero everywhere then the ? rst derivative cannot decrease so the function is convex. This gives a way of testing whether a function is convex. Find the second derivative; if the second derivative is positive or zero everywhere then the function is convex. 2. 1. 3Concave functions Concave functions are important in the theory of the ? rm. A function is concave if the straight line joining any two points on the graph of the function lies entirely on or below the graph as illustrated in ? gure 3. Another way of looking at concave functions is that they are functions for which the set of points lying below the graph is convex. Figure 3 suggests that if the ? rst derivative of a function does not increase anywhere then the function is concave. This suggestion is correct. If the function 2 Convexity Mathematically a set is convex if any straight line joining wo points in the set lies in the set. Which of these sets are convex?

This gives a way of testing whether a function is convex. Find the second derivative; if the second derivative is negative or zero everywhere then the function is concave. You may ? nd it easier to remember the di? erence between convex and concave functions if you think that a function is concave if it has a cave underneath it. 2. 2 2. 2. 1 Convexity in consumer theory De? nitionThe convexity assumption in consumer theory is that for any (x10 , x20 ) the set of points for which u(x1 , x2 ) ? u (x10 , x20 ) is convex. If utility is strictly increasing in both x1 and x2 so the indi? erence curve slopes downwards the convexity assumption is is equivalent to an assumption that thinking of the indi? erence curve as th e graph of a function that gives x2 as a function of x1 the function is convex. ?u ?u > 0 and > 0 so the indi? erence Thus if the test for nonsatiation establishes that both ?x1 ?x2 curves are downward sloping the convexity assumption can be tested by rearranging the equation for an indi? rence curve to get x2 as a function of x1 and u, and then ? nding whether the second derivative ? 2 x2 > 0. ?x2 1 2. 2. 2 Example: testing for convexity with a Cobb-Douglas utility function 2/5 3/5 Here u(x1 , x2 ) = x1 x2 . Write 2/5 3/5 u = x1 x2 . (3) Rearranging to get x2 as a function of x1 and u ?2/3 x2 = u5/3 x1 . Holding u constant so staying on the same indi? erence curve ? x2 2 ?5/3 = ? u5/3 x1 ?x1 3 and 10 5/3 ? 8/3 ? 2 x2 = >0 u x1 ?x2 9 1 4 (4) ?u ?u > 0 and > 0 the indi? erence ?x1 ?x2 curve is downward sloping and the preferred set is above the indi? rence curve so the convexity condition is satis? ed. so on an indi? erence curve x2 is a convex function of x1 . Beca use 2. 2. 3 Algebra problems You should know how to rearrange equation 3 to get equation 4. If this is causing you problems note ? rstly that equation 3 implies that ? ?5/3 2/5 3/5 2/3 u5/3 = x1 x2 = x1 x2 so x2 = 2. 3 u5/3 2/3 x1 ?2/3 = u5/3 x1 . Beyond EC201 Concavity and convexity can be de? ned algebraically and this is essential if you want to prove any results about concavity and convexity rather than appealing to intuition as I have done here.The procedure I have given for checking the convexity condition in consumer theory requires that the ? rst ? u ?u derivatives > 0 and > 0 and does not work with more than two goods. There is a much ? x1 ?x2 more general method; write down the matrix of second derivatives of the function u (x1 , x2 ). If this matrix is positive semide? nite everywhere the function is convex, if the matrix is negative semide? nite everywhere the function is concave. You do not need to know about this for EC201. 5

A Research Study Of Sociology - 1708 Words

Scientists have been looking over groups and societies and observing them for many years. In doing this they were examining individuals of different social classes along with statuses and observing their role in humankind this they labeled as the study of sociology. This evolved into a form of study beginning in the 19th century as scientists began to observe and study differences in social classes among people. The way people communicate together, the way they act, and the way they work together as groups of people is the sole base for this type of science. By looking at these traits, sociologists were able to decide how and why people behave or react in the ways that they do. They are able to observe patterns of behavior which can predict potential models of growth or change, and they can use these analyses to try and give solutions to problems in society. One such analyses is that of anomie, anomie, also spelled anomy , is in societies or individuals, it is a condition of instabil ity resulting from a breakdown of standards and values or from a lack of purpose or ideals within said individual or society. (Kendall, 2014) The term was first introduced by the French sociologist Emile Durkheim in his study of suicide. Durkheim was born in the mid-19th century in France, where he was the son of a Jewish rabbi.
