The Life of Louis Pasture essays
The Life of Louis Pasture essays On December 27, 1822, a miracle happened in a little village near the eastern mountains of France called Dole. This miracle would later be recognized all around the world as one of the greatest scientists who had ever lived. He would be the one to save a little boy in need of help. He would be the one to save animals that were near death. He would be the one who would change the way the world lived forever. His name was Louis Pasteur, founder of the antidote for rabies, anthrax, chicken cholera, and many more life-threatening diseases. Louis father, Jean-Joseph, was a skilled tanner who made leather out of animal hides for a living. Since the tanning business was in the family, many expected Louis to follow in his fathers footsteps. However, Jean-Joseph and his wife, Jeanne Roqui, had bigger dreams for their son. They sent Louis to a school in Paris when he was 16 years old in hopes that he would return home to be a teacher at a local school. However, their hopes were shattered after just one month. Louis had a terrible case of homesickness. He went on to college in Besancon, and furthered his education at Ecole Normale Superieure. As a result of his academic experiences, Louis went on to study topics in science. Louis Pasteurs first job was in crystallography (which means the production of crystals from chemical substances). He later became known as the founder of stereochemistry at the age of 26. Louis fulfilled his parents dream and became a schoolteacher, and was later promoted to Professor of Chemistry at the University of Strasbourg. At the University, he met and later married a woman named Marie Laurent, who was the daughter of the head of the University. Louis and Marie had five children, however, only two survived past childhood. Determined to protect children from diseases, Louis began his scientific research. One of the blessings that came to Louis Pasteur was a nine-year-old boy named Jose...

Find the Inflection Points for the Normal Distribution
Find the Inflection Points for the Normal Distribution One thing that is great about mathematics is the way that seemingly unrelated areas of the subject come together in surprising ways. One instance of this is the application of an idea from calculus to the bell curve. A tool in calculus known as the derivative is used to answer the following question. Where are the inflection points on the graph of the probability density function for the normal distribution? Inflection Points Curves have a variety of features that can be classified and categorized. One item pertaining to curves that we can consider is whether the graph of a function is increasing or decreasing. Another feature pertains to something known as concavity. This can roughly be thought of as the direction that a portion of the curve faces. More formally concavity is the direction of curvature. A portion of a curve is said to be concave up if it is shaped like the letter U. A portion of a curve is concave down if it is shaped like the following ∠©. It is easy to remember what this looks like if we think about a cave opening either upward for concave up or downwards for concave down. An inflection point is where a curve changes concavity. In other words it is a point where a curve goes from concave up to concave down, or vice versa. Second Derivatives In calculus the derivative is a tool that is used in a variety of ways. While the most well-known use of the derivative is to determine the slope of a line tangent to a curve at a given point, there are other applications. One of these applications has to do with finding inflection points of the graph of a function. If the graph of y f( x ) has an inflection point at x a, then the second derivative of f evaluated at a is zero. We write this in mathematical notation as f’’( a ) 0. If the second derivative of a function is zero at a point, this does not automatically imply that we have found an inflection point. However, we can look for potential inflection points by seeing where the second derivative is zero. We will use this method to determine the location of the inflection points of the normal distribution. Inflection Points of the Bell Curve A random variable that is normally distributed with mean ÃŽ ¼ and standard deviation of ÃÆ' has a probability density function of f( x ) 1/ (ÃÆ' √(2 À) )exp[-(x - ÃŽ ¼)2/(2ÃÆ'2)]. Here we use the notation exp[y] ey, where e is the mathematical constant approximated by 2.71828. The first derivative of this probability density function is found by knowing the derivative for ex and applying the chain rule. f’ (x ) -(x - ÃŽ ¼)/ (ÃÆ'3 √(2 À) )exp[-(x -ÃŽ ¼) 2/(2ÃÆ'2)] -(x - ÃŽ ¼) f( x )/ÃÆ'2. We now calculate the second derivative of this probability density function. We use the product rule to see that: f’’( x ) - f( x )/ÃÆ'2 - (x - ÃŽ ¼) f’( x )/ÃÆ'2 Simplifying this expression we have f’’( x ) - f( x )/ÃÆ'2 (x - ÃŽ ¼)2 f( x )/(ÃÆ'4) Now set this expression equal to zero and solve for x. Since f( x ) is a nonzero function we may divide both sides of the equation by this function. 0 - 1/ÃÆ'2 (x - ÃŽ ¼)2 /ÃÆ'4 To eliminate the fractions we may multiply both sides by ÃÆ'4 0 - ÃÆ'2 (x - ÃŽ ¼)2 We are now nearly at our goal. To solve for x we see that ÃÆ'2 (x - ÃŽ ¼)2 By taking a square root of both sides (and remembering to take both the positive and negative values of the root  ±ÃÆ' x - ÃŽ ¼ From this it is easy to see that the inflection points occur where x ÃŽ ¼  ± ÃÆ'. In other words the inflection points are located one standard deviation above the mean and one standard deviation below the mean.

Training and development Essay Example | Topics and Well Written Essays - 1000 words
Training and development - Essay Example This research will begin with the statement that the Human Resource Development process has become an essential component of organizational ascent in the present diverse as well as the global scenario. New skills and learning ability need to be inculcated by the senior HRD managers in their staff in order to achieve success. They need to ensure a continuous and ongoing learning process for the staff to avoid stagnation and rigid ideas. The process itself needs to be applied in a phased manner. The HRD managers should be able to establish a working relationship with the staff and they should possess skills and capabilities to train, coordinate and identify problems faced by the employees in terms of changed scenarios like diversity, global competition, and necessary new skills. They should be able to identify both external and internal factors influencing employee behavior. They should be able to influence employees by leadership qualities and noncoercive methods of persuasion. They s hould use both personal outcomes and organizational outcomes as a motivating factor for the employees. The trainee characteristics and their trainability need to be evaluated and decisions made accordingly. The lack of participation in the training and development programs can be both due to extrinsic and intrinsic factors. The external factors which might have contributed could be the job environment and prospects prevalent in the country in the immediate future, financial strength of the students or fear of enormity/comprehension of the courses offered.

MicroL4 Essay Example | Topics and Well Written Essays - 1000 words
MicroL4 - Essay Example Higher education has proved to be beneficial in voting matters also. Education is an asset. It has provided benefits like self awareness, ability to think wisely and critically, having the ability to meet different people, which are less tangible and will help a child to grow up being a better individual. However, there are certain costs that have to be incurred for going to college. The opportunity costs of going to college include several components. First, the opportunity cost of one going to college includes the money that he or she would have earned instead of attending classes. It also includes the amount of wages that were foregone by not doing work and just attending college. In opting for going to college, one has also lost the opportunity to build up a career and the associated income that could be earned instead of not going to college. The greatest opportunity cost of going to college is the wage income that the individual has to forgone for attending classes. 2. The marg in is considered to be a very significant concept in the area of business and economics. In economics the concept of margin is related to a wide range of topics including utility, revenue, costs, profit, product, etc. We are quite familiar with the terms of marginal utility, marginal revenue, marginal costs, marginal profit, marginal product and so on. The term margin mainly stands for the difference in the value of a variable when one additional unit of some other variable is used. For example, marginal utility of a product refers to the increase or decrease in total utility of an individual due to one unit increase in the consumption of the product. The concept of margin is very essential in economic decision making. The level of p of goods, the level of production of goods, etc are always determined by considering marginal requirement. For example, a firm is a profit maximizer in the sense it will always produce a commodity in such a way that its profit is maximized. In a perfect ly competitive market, the firm will maximize its profit when marginal costs will b equal to its marginal revenue. The firm will continue to increase its production until marginal revenue becomes equal to its marginal cost. The point of equality is considered to be the equilibrium point of the firm. Thus the concept of margin is very important in economic decision making. Without the consideration of margin requirement it is not possible to conduct economic activities in optimum ways. However, it is not always necessary that all kinds of economic decisions are taken using the marginal concept only. For example, in a perfectly competitive market the break even point of a firm is not determined by any marginal concept. The break even point is relevant in short run production. This point mainly refers to the point of shutting down of production. A firm in a perfectly competitive market will shut down or stop production in short run when its average variable costs become greater than it s average revenue, i.e. its average revenue even fail to cover the firm’s average variable costs. Thus the concept of average is important in taking shut down decision. 3. There has been a huge debate over the tax cut policy by bush administration in 2001 and 2003. Bush tax cuts mainly refer to two important tax policies created and implemented during the Presidential era of George W. Bush. Through these policies, the Bush administration mainly lowered tax rates in the United States. These tax policies effectively lowered marginal tax rates for almost all

A Critical Analysis Of Patriarchy Sociology Essay
A Critical Analysis Of Patriarchy Sociology Essay In the article Patriarchy, the System, Allan Johnson defines patriarchy, and in doing so addresses the common misconceptions and stereotypes that people inaccurately identify with the term. He argues that people tend to generalize and attach the term patriarchy with men, and therefore come to the conclusion that all men are oppressive people. [1] Johnson recognizes a pattern in which women feel free to blame men for oppressing them and therefore men take it personally and become defensive. He argues that women will blame men for patriarchy simply because theyre men. [2] Johnson also considers the possibility that perhaps people are simply confused, that they cannot distinguish the difference between patriarchy as a system and the individual. He argues that people have to recognize this, and examine larger contexts, in order to solve social problems. Johnson suggests that race, gender and class oppression are not actually oppression, but rather the sum of individual failin gs. [3] Johnson argues that in order to solve social problems, these misconceptions must be cleared up. If were ever going to work toward real change, its a confusion well have to clear up. [4] Johnson effectively identifies common misconceptions about patriarchy, and convincingly argues that this ignorance and individualist perspective is contributing to problems within society. Allan Johnson goes on to argue that patriarchy is organized around relationships and shared understandings, and he argues that this can limit you to some degree. [5] Johnson provides an interesting perspective on how we participate in our social lives. He makes a very good point when he suggests that patriarchy can exist without men being portrayed as the villains. People tend to follow along with what society deems is the norm. This is significant; as it explains why individuals make the decisions that they do, in a larger social context. Johnson further analyzes what patriarchy really means, and explains that it is simply part of our culture, and the symbols and ideas within it. He argues that the make up of patriarchal culture is important to understand because it affects the structure of social life. [6] He discusses the possibility that culture enforces gender roles and power positions, therefore shaping and influencing our values. Allan Johnson goes on to say that everyone contributes to patriarchy, the system, whether theyre aware of it or not. We are all involved in patriarchy, but it does not necessarily mean that women are the victims, and men are the oppressors. He explains that who we think we are is closely related to who others think we should be and where we fit in social systems. He sums up his ideas by stating that all men and women are involved in patriarchy because we occupy social positions. [7] This further proves his point, that patriarchy cannot be constrained to individuals themselves, as patriarchy is beyond the individual experience. This article studies the concept of patriarchy as a framework. It provides a sociological perspective on social inequalities and attempts to explain why they exist. Johnson convincingly argues that people dont truly understand the origins of patriarchy. He has taken the term patriarchy and uses a sociological approach to uncover what it really is, a social construction or framework. He defines patriarchy in broader social terms and effectively proves that there may be oppressive individuals in society but patriarchy is not the result of all men being oppressive people, it is the result of individuals collectively possessing power. The sociological approach that Johnson uses helps to examine and analyze society as a whole, a structure in which everyone participates in and contributes to. This approach can help to explain why individuals act out certain behaviors in their own social lives. Perhaps people behave in such patriarchal ways because the system has influenced us in such ways. Maybe gender oppression has nothing to do with men being patriarchal, but more to do with how our society has been constructed and how our culture and our ideas about men and women have been shaped within it. Johnson helps us to use our sociological imagination to better understand the problems society currently faces. To conclude, Allan Johnsons article Patriarchy, the System can help us to analyze society in broader social terms in order to understand systems like patriarchy and our participation within these larger systems. Johnsons article helps us to use a sociological perspective to better understand the individual and why things like gender oppression occur. This article is useful, as Johnsons argument could be applied to other social contexts as well. This article allows us to further our knowledge of social constructions and how we participate in them, and therefore how we can change them to improve equality and eliminate the ideas present in our culture that limit us.

An Analytical Essay on Hamlet as Ghost Story, Detective Story and Revenge Story :: The Tragedy of Hamlet Essays
An Analytical Essay on Hamlet as Ghost Story, Detective Story and Revenge Story  William Shakespeare's play Hamlet, is a ghost story, a detective story and a revenge story all within one plot. Throughout the play, qualities of all three types of stories are displayed. The ghost story consists of Hamlet Senior and the circumstances surrounding his untimely demise at the hands of the present King, Claudius. He is being tortured in hell until his death is properly avenged. The detective aspect of Hamlet is brought about by Hamlet trying to figure out whether or not his fathers ghost was real and also to what, if any extent, his mother the "virtuous" Queen Gertrude was involved with the murder of his Father. Both Hamlet and Laertes, bring yet another aspect to this most versatile play, by seeking revenge for their fathers death, each in their own way. By viewing the play as either one or all of these different aspects we learn to have different perspectives on the play.                                                                    The story of Hamlet Senior's death is the ghost story aspect of the play. Hamlet Senior, the late king, was being tormented in hell throughout the daylight hours and during the night he was forced to walk the castle. He stated that he was "Doom'd for a certain term to walk the night, And for the day confin'd to fast in fires, Till the foul crimes done in my [being the late King's] days of nature Are burnt and purg'd away (50 lines 10-13). His release from this torture would not be permitted until his avenger is retaliated against by his son. Hamlet, Francisco and Bernardo all see the ghost of the late king, but the apparition will only speak to his son. The ghost brings an unnatural feel to the drama and leaves the reader/viewer wondering if it was real or all in Hamlet's mind.                                                            Hamlet is made to do some detective work in this melodrama. His first order of business was to figure out if the ghost of his father that he thought he saw, was in fact real and if it was, was it unfeigned or a demon. Then, he must decide if the ghost of his father was truthful about Claudius, his father's brother, Hamlet's uncle who was also the reigning King, committing fratricide against his father. To find evidence of Claudius' involvement, Hamlet uses the players, to bring about his uncles deep seated feelings hopefully lodged in his conscience.
