Gay marriage Essay

Homosexual marriage is one of the old but controversial issues around the world. Compared to the past, it seems to become a more open debate among people. At the same time, people seem to be more swayable than before, but towards the gay marriage, different voices have still been hovering in the air. Gay people and their supporters have been striving for their rights to get married legally, while others who against gay marriage have never stopped deterring it. Strongly against gay marriage is the central theme of Louis P. Sheldon’s article Gay Marriage â€Å"Unnatural†. According to the author’s views, gay marriage is ‘unnatural’, and it is contrary to the essence of the marriage. Meanwhile, it disobeys Americans social values as well as against their standards. In explaining his perspectives, the author has stated that â€Å"homosexual marriage† is rejected by main Americans according to the polls. In particular, he assumes that gay marriage is both culturally and physically incompatible since the gay people lack of reproduction capacity, to do so, third person has to be involved, which violates the nature of marriages. Drawing on to sustain his views, the author claims that the majorities’ wishes and values of their communities have been unconcerned by judges. Instead, the gay people start to gain more special rights from the judicial tyranny throughout America. Therefore, churches might have to face civil suit for failing to perform homosexual marriage. To reinforce his views, the author insists that it is a chosen behaviour rather than genetic because no reputable medical organizations have ever asserted that is biological. Finally, in the article, Sheldon has restated the poll that 80 percent of Americans are opposed to homosexuals marriage. How believable though, is his statements that according to every reputable public poll approximately 80 percent of Americans are against the same sex marriage? First of all, cogitation on the data, which the author draws on to  support his views, are required. The numbers he presented seem attractive and persuasive, but it is worth noting that no source has been provided for them, so readers do not know how trustworthy they are. In my view, it would be more convincing for example to try referencing the data in his claims like the quoted above as well as the gay people’s average income is twice higher than that of non-gay people in America, and his figures will not be questioned. The author of this article can therefore be criticised here for a lack of citation of sources to back up his views. Another questionable aspect of this article is its hidden premises. Although the author does not openly state that the marriage should be generational, otherwise they should get divorce, this could be understood from the authors’s statement that gay marriage is â€Å"not generational†. While marriage is not only about generating offspring but also means love. It is an insulting claim for the couples who in love but unfortunately could not have children might because fertility problems, health issues, over age, their chosen life style of Dink family, so do they have to separate with each other just because of that? Is it really the essence of marriage? I do not think so. In my view, whether to have kids or not in couples’ marriage lives, it is a matter that couples, including gay couples need to consider and judge not by other irrelevant people, and it should not be an excuse to despoil others rights to get married. Anyhow, the quality of this article has been deg raded due to the hidden premises. The author also commits the fallacy of unsubstantiated claims. He insists that â€Å"Homosexuality is a behaviour-based life-style.† However, there is no further explanations on why he asserts that can be found in this article. Besides, it seems that he also has no evidence to proof that is a chosen behaviour. Furthermore, he mentions that homosexuality people only take up 10 percent of the whole population in America, while the data he referred is not substantiated. Despite these shortcomings, Sheldon’s article still has some value and we need to judge it in terms of the author’s purpose in writing it. It is not intended to be a rigid piece of academic work, but is mainly focused on  arousing people’s attention as well as persuading them to against the legalisation of gay marriage. Therefore, the author has employed loaded words in this piece which have greatly improved the pothos of the article. For example, he uses â€Å"a dead – end street†, â€Å"hardware problem†, â€Å"judicial tyranny†, â€Å"cry the shrillest claim of victimhood†, â€Å"single out† and â€Å"sanitise†. These words could easily grasp readers emotions and lead them act immediately without further considered judgment. Finally reaches his purpose of writing this article. Personally, I think he has successfully applied loaded words in this article.

Communication Breakdown

Communication Breakdown Deborah Tannen in her essay â€Å"Sex Lies and Conversation† points out the problems in communication between genders. She focuses on conversational styles and on how a person’s expectations of one’s reaction may cause misunderstanding. She emphasizes the importance of something she calls cross cultural communication. Tannen believes that in order to communicate properly with the opposite sex we must learn their culture and adapt to conversation with them. First, Tannen describes the differences in how children socialize.Most of what we know about communication we learned when we were children. When women are little girls, they have best friends, ones we can share our secrets with. When we get a little older and have a relationship with the opposite sex we expect the same kind of communication. Tannen believes the importance is not necessarily the topic but the feeling that you get from conversation and points out ,â€Å"What is important is not the individual subjects that are disclosed but the sense of closeness, of a life shared, that emerges when people tell their thoughts, feelings and impressions† (51).We must learn to socialize with the opposite sex the same way we do with the same sex. If we could learn to connect and have the â€Å"sense of closeness† with the opposite sex we might be able to communicate successfully. Tannen’s research has shown that men socialize differently as boys and â€Å"Since they don’t assume talk is the cement that binds the relationship, men don’t know what kind of talk women want, and they don’t miss it when it isn’t there†(51). Tannen points out that boys learn to communicate in larger groups, often struggling not to be in the subaltern position of the conversation.Men do not like to listen; they like to feel like they are the superior person in the conversation. (51) Communication starts in childhood and what we have learne d to expect from conversations. Next, Tannen observes how men and women listen to each other and how this can cause misunderstanding between genders . She feels that there is confusion about what women expect and declares, â€Å"When women talk to each other in a close, comfortable setting, they often overlap, finish each other’s sentences and anticipate what the other is about to say† (53).Tannen also talks about listener noise. Women often will say â€Å"mhm† or â€Å"uhuh† and men do not do these things when they talk to each other. Women are looking for that â€Å"listener noise† and if he is silent, she thinks he is ignoring her but on the same token Tannen notes, â€Å"Men who expect silent attention interpret a stream of listener noise as overreaction or impatience† (53). Body language and conversational habits are causing women to feel like they are being ignored and men to feel as if they are being interrupted.When a woman is having a conversation they expect the listener to â€Å"express agreement† and be supportive of the conversation. Men, on the other hand, feel it is their conversational duty to express other positions in the argument. (53) Learning the importance of building a rapport with the person you are talking to may be another way to have successful conversation with the opposite sex. Finally, Tannen believes that learning how the opposite sex communicates is the key. If we can learn what to expect when communicating with someone then we can learn how to respond.Tannen suggests â€Å" A sociolinguistic approach by which male-female conversation is seen as cross- cultural communication allows us to understand the problem and forge solutions without blaming either party†(54). Tannen stresses the importance of telling the other person how you feel about their communication with you and advises,† Women who feel abandoned and deprived when their husbands won’t listen to or re port daily news may be happy to discover their husbands trying to adapt once they understand the place of small talk in women’s relationships† (55).It is really not the male or females fault that we communicate the way we do but it is our fault if we do not speak up and tell them it bothers us. When we are in a relationship with another person we just have to adapt to the way they communicate to make the relationship work. If a woman learns to accept that her husband is not going to communicate with her like her best girlfriend did in her childhood then she can look for other people to hold those types of conversation with. (55) Learning to communicate with the opposite sex involves many different things.Communication is something that is learned in childhood but mostly with the same sex. In order to have a successful relationship with good communication we must understand that men and women have very different body language when communicating and that they do not respo nd the same. Accepting that there is a difference in the communication of genders and learning to adapt is paramount in relationships. Tannen, Deborah. â€Å"Sex, Lies and Conversation. † The Norton Mix.

Evaluation of advertisement campaign Essay Example | Topics and Well Written Essays - 1000 words

Evaluation of advertisement campaign - Essay Example Interestingly, the overall mobile phone market is growing at a faster pace than predicted, which signifies the immense potentiality of the industry. So the big question revolves around this mammoth progress and whether it is triggered by product innovation only or any other factors that had led to this colossal growth and development of the industry (Campbell, 2009). On deeper analysis, it has been observed that the role of advertisement is paramount in the development. One of the key trends of this industry is that companies invest large sums of money to create awareness about their products and services and these investments pay off to a great extent (Clifton, 2012). The market size of this industry is so large that almost every player has space for themselves. However, a company with better advertisement strategy and campaign experiences greater success. Thus, the impact of advertisement on the growth of mobile phone industry is clearly visible (Adler, 2010). In this report, the i mpact of advertisement on the growth and development of a product will be addressed. However, the study will not be accomplished in the usual way like, industry analysis, which identifies the way or the extent to which advertising plays an effective role. Rather the study will select an advertising campaign of a company belonging to the mobile phone industry. In this context, the advertising campaign by Samsung will be chosen and the same will be evaluated. Campaign Strategy/ Rationale Advertising is a necessary activity to all businesses for the sole purpose of generating awareness about the products and services and at the same time, influencing the target customers to buy the product. It is impossible to sell a product without letting the customers know about it (Aarika-Stenroos and Sandberg, 2012). Thus, advertising is dubbed as a tool that helps to draw attention of the consumers towards the products or services of the company. Advertisement campaigns can be carried out through various mediums such as, television, radio, social media or any other traditional forms. Usually, a company targets several groups of customer on the bases of the product characteristics and consumer requirements and as a result of that, the company makes use of more than one channel so as to ensure that the messages of the company reach every target audience. Several scholars have even emphasized on the fact that advertising campaigns are the means that help a company to sustain in the marketplace (Alle, 2000; Amit and Zott, 2001). Furthermore, echoing the same statement, another set of industry experts and academicians have pointed out that advertising campaigns along with product promotion also greatly helps in understanding the requirements of the consumers as well as the sort of prices that the customers are willing to pay for the ownership of a particular product. Advertisement campaigns also play indispensable roles in updating the consumers about the new developments and pr oduct launches (Ballon, 2007). Hence, it creates customer loyalty that in turn brings sustainable competitive advantage for the firm. However, one of the key aspects of companies, undertaking advertisement campaigns, is that each campaign has a particular rationale i.e. advertisement campaigns are designed in such a manner that it succeeds to fulfil one of the crucial objectives of the firm

A productive and committed workforce will drive the organization towards attaining its short term and long-term goals more effectively notwithstanding the various social and economic challenges facing the organization (Bulger & Reiser, 2009). Healthcare organizations must use the available resources wisely and efficiently to produce value quickly during tough times when the organization operates on tight budget. Sometimes the organization might resort to cut the labor costs to enable it gather extra funds to carry out other essential tasks aimed to improve quality of services. One of the greatest challenges facing contemporary healthcare organizations in their attempt to improve delivery of services is ways of managing the efficiently. For a team of healthcare personnel, key insights along with business intelligence innovation would yield substantial value in the short term (Bulger & Reiser, 2009).

Incidentally, many of the healthcare professionals will obviously feel demoralized by attempts to slash their wages and salaries following the drive to reduce labor expenses. The organization should largely focus on cutting expenditures on less productive labor, as well as activities that add little value to

External and Internal Environments - Research Paper Example However, the sales of the Nokia products take place in around 150 countries. The company is the second best producer of mobile phones and makes annual revenue of approximately thirty eight billion pounds. The company’s market share is around 22.5 percent (Luo, 2000). One of the general environments that affect Nokia Company is international. This factor illustrates those events that are taking place in other foreign countries. The dimension of international type of environment influences many other factors of the external environment of a company. These factors include the coming up of new customers, competitors, the reliable suppliers, social shapes, trends of the economy and technology. Nokia Company has an obligation to compete with other companies globally. Samsung Company is one of the competitors that have outweighed Nokia Corporation from being the best vendor as from the year 1998 to the year 2012. The coming up of smart phones which are made by other vendors, has redu ced the market share of Nokia Corporation. To solve this problem, the company made a strategy to collaborate with Microsoft Company so that the mobile phones (smart phones) produced will have an operating system incorporated by Microsoft’s phone type of windows (Mimoun, 2009). ... In case the company does not lower its prices, then it has to increase the features of its products. Comprehensively, when similar products from different companies have varying costs in that one company sells at a lower price, and the other one sells at a higher price, the one with the lower price will be the consumers preference and choice. Therefore, Nokia Company must do something worth either by decreasing the prices of its products or improve the quality of the mobile phones (Steinbock, 2010). This will help the corporation increase its share in the market. Another general factor of environment that affects Nokia is technology. Technology is one of the most developing things in the world. Several companies are coming up with new, innovated technology in the industry. Coming up of newer phones with a high level of technology, affects the industry greatly. Nokia Corporation has to ensure that it involves many innovations and advancing of technology, by embracing any change to ens ure that the products are in the same level with the technological growth. Many companies have come up with better-advanced technology level. These companies include Samsung and other producers of smart phones. Therefore, if Nokia will not be more creative and strategically improve the technology of its products, it will loose to its competitors (Daft & Marcic, 2010). In every business, there are major internal factors that affect it either positively or negatively. These factors are those that are within the organization itself. Capital is one of the factors that affect Nokia. For the corporation to do innovation and advance technology, it requires large amounts of capital. Fixing new soft wares and features in the mobile

Smoking in communal places needs to be prohibited Essay Example for Free

Smoking in communal places needs to be prohibited Essay Smoking in communal places needs to be prohibited. All of us have heard about the secondhand smoke’s negative paraphernalia to human health, newly done investigation is usually dropping lighting about just how effective it actually is. A current analysis through the United National Institute on Drug Abuse (NIDA) observed that will secondhand smoke causes it to be more difficult with for smokers to give up smoking (Marzilli 2008). Analysts point out that secondhand smoke sets off nicotine cravings  which can adjusts brain purpose, compared to truly smoking cigarettes a smoke. In the event secondhand smoke possesses a real effective effect on smokers, and then what exactly should it complete for you to those that aren’t possibly lighting up? Secondhand smoke poisons others, in particular kids as well as pregnant women, at risk of breathing in cigarettes’ smoke. Furthermore, smoking in communal places endangers individuals who have the respiratory system health disorders. Tobacco contains the Carbon (II) oxide, which if inhaled will lead to the reduction of the carrying capacity of oxygen in the blood (Buddelmeyer Wilkins 2010). Carcinogenic compounds which is also present in tobacco is said by research to cause mutation of the DNA to any individual who inhales it and as a result lead infection cancer (Buddelmeyer Wilkins 2010). In a matter of fact, smoke from a burning cigarette ingests most to a non-smoker and does not get sucked in by the smoker’s lungs furthermore he/she escalates it to the air. The latest scientific tests display that nearly 69.79% of individuals ingesting cast-off smoke from communal smokers have a larger chance of getting respiratory system troubles when compared with smokers themse lves (Qwins 2013). Tens of thousands deaths per year are as a result of the effects of secondhand smoke of which are categorized into two thus; lung cancer and heart disease. Prohibiting smoking in public regions is often useful in several ways since it eradicates an act involving difficulties to acquitted individuals. In the event of prohibiting smoking of cigarettes in communal places, we lower or even totally remove the chance of placing non-smokers susceptible and or increasing the smokers’ chances of creating lung and heart glitches to themselves. Additionally, when many of us prohibit smoking cigarettes in communal places, many of us also cease the smokers from additionally increasing their likelihood of getting medical problems pertaining to themselves. Research clearly points out that prohibiting smoking in public areas saves more than 15 million heart attacks and 20 million lung cancer attacks a year nationwide (Qwins 2013). Though it is usually mentioned that not every individual who smoke in communal regions usually led to harming other people, It remains undeniable fact that cigarette smoking by itself is really a reason for health disorders. Its not ample to convey which the size of impacted individuals is relatively just a small fraction; profuse or perhaps few of, an individual put in danger is usually ample. It can be just the situation with cigarette smoking in communal places, therefore, needs to be restricted. References Buddelmeyer, Hielke, and Roger Wilkins.

Impact of Conflict on Human Capital Development

Impact of Conflict on Human Capital Development Living Amid Conflict and its Implications to Human Capital Development By Alexander Ken P. Libranza Introduction The adverse effects of the outbreak and recurrence of conflict can be dangerous because of its long-term economic implications that may force a country into a vicious cycle of low human capital development and conflict (Kim et al, 2010). A common stand among recent literature suggests that conflict destroys the process of accumulating physical and human capital, which deteriorates the labor force and in turn affects institutional capacity (Justino, 2011; Nkurunziza, 2008; Serneels et al, 2010). Most researches on civil wars and armed conflict has been focused on the macro-level of analysis, as noted by Stewart Valpy (2001), that largely address the economic and social consequences concentrating on the prevalence of underdevelopment among conflict-affected countries. However, very few researchers talk about the micro-level impacts of conflicts on household and individual. One possible reason is the unavailability of household-level data in conflict-affected countries. Second, even wh en such data are available the reliability of the source and the sample is also being questioned. Although, empirical works are growing, the increasing micro-level researches has been greatly focused on the effects of war to household living standards and direct impacts of combats that involves narratives of individuals in conflict areas. Very limited works has addressed the long term effects of violent conflict on children and child development, most especially on the Philippine context. Drawing on a review of both theoretical and empirical literature, this paper frames the connection between armed conflict and human capital development within a conceptual framework in which the accumulation of nutrition and education and levels of human development are linked. This paper further shows that while armed conflict might be caused by many factors, low levels of human development increase the risks of conflict outbreaks and recurrence. Figure 1: Adopted from Kim Conceià §Ãƒ £o (2010), â€Å"The Economic Crisis, Violent Conflict, and Human Development† Figure 1 shows the conceptual framework of the study. This framework suggests a self-reinforcing cycle from the roots and cause of armed conflict to low human capital development, and vice versa. The decade-long armed conflict in the Philippines is a proof of this loop. Concentrated in rural areas, variations of insecurities and violence has affected communities especially children and women who are forced to suffer physical and psychological trauma as consequences from shooting, combat operations, and rights abuse. While conflict maybe caused by many factors, Risser (2007) traces its roots to the issues of poverty, economic distribution disparities, and scarcity of state social and welfare services. These becomes a problem because it limits access to health care services and basic education which is critical for the accumulation of physical, social, and human capital. The framework further notes that a country experiencing conflict cannot secure long term returns for investments in both physical and human capital, resulting in low investment in health and education which lead to low levels of human development. A country with low levels of human development has a difficulty in improving institutions which lowers productivity and potential growth. As such, lower growth rates heighten the risk of conflict, potentially trapping a country in a self-reinforcing cycle of conflict, low human development, and vice versa (Kim Conceicao, 2010). In the period of 2001-2005, IBON Foundation monitored 1,061 armed confrontations between the government forces and various armed groups and recorded 569 killing of innocent, unarmed civilians – 52 of which are minors under 18-years old, 63 women, and 199 who were killed during the crossfire. Over the last decade, millions of children were killed in armed conflicts all over the world (Machel, 1996). While others are exploited as soldiers and exposed to extreme brutality and violence (Camacho, 2003). It is estimated that 45 percent of the direct victims of armed conflict are 15 years old and younger. Moreover, there were 819 incident of human rights violations involving children from 2001 to April 2005. Children suffered effects of sexual violence, harassment and psychological trauma, intimidation, illegal detention, and exposure to hunger and disease. There were 75 cases of children who were orphaned when their parents were killed during the conflict, however this number may be underreported due to the lack of data, limited information, and unreliability of the sources. Exposure to actual combats and being caught in the crossfire of battles has left them physically disabled, emotionally scarred, and psychologically traumatized which are detrimental in accumulating the proper human and social capital to become well-adjusted and productive workers. This research relates to various fields in the literature, in particular for development economics, health and nutrition, and education. I briefly mention below the key areas in the mentioned field of study that motivates this research. First is on the established link between economic conditions and conflict. There has been a great deal of work analyzing the causal effects of conflict and war. Most of these studies extensively focused on establishing a strong link between poverty to armed conflict and violence (Justino, 2006; Justino, 2009; Miguel et al., 2004). Macro-level analysis, as noted by Stewart, F. Valpy F. (2001), has provided an insight on the economic and social consequences of conflict focusing on the prevalence of underdevelopment among conflict-affected countries. However, there has been limited number of studies focusing at the micro-level impacts of conflicts on household and individual. The increasing micro-level data has been greatly focused on the effects of war to household living standards, direct impacts of combats, and very limited on children and child development especially on the Philippine context. Second is the relationship of health to socio-economic characteristics, and its implications to consumption patterns. Serdan (2008) gave an overview of how armed conflict affects food intakes, food availability, and a clear measurement indicators of nutritional outcomes for children. In addition, Straus and Thomas (2008) noted how health and nutrition affects the accumulation of human capital, as well as its positive effects to productivity and living standards. Third is relating nutrition to academic performance. In fact, academic performance and nutrition, as important elements in the accumulation of proper human and social capital, has been the subject of the growing literature demonstrating the long term impacts of conflict to the productivity of the workforce, their well-being, as well as living standards (Thomas, 2007; Berhman et al., 2004; Malluccio et al., 2006, Serdan, 2008). Furthermore, a unanimous agreement establishes health as an important factor for determining the well-being of the population which affects schooling, income, and labor force participation (Serdan, 2008; Alderman et al., 2006; Shemyakina, 2006; Swee 2009). In all, existing researches are clear: the effects or armed conflict and violence represent a significant challenge to the health and education systems. This further qualifies both the short-term and long-term economic implications of armed conflict to the different sectors of the economy. This paper examines the possible causal effects of armed conflict and violence on health outcomes and education of children. In particular, I analyzed if the exposure to armed conflict and violence has a differential effect on the nutrition and academic performance of conflict-affected children, and comparing these results to those children from non-armed conflict areas. When it comes to peace development, this quantitative research will contribute to the lack of data around conflict-affected areas towards creating an impact assessment for conflict and post-conflict rehabilitation programs. The main issue is the gap between academic studies and practitioner works that has been due to the limited information and reliance on sources of data from mass media and humanitarian monitoring mechanism. I want to establish a closer link between academic studies and policy making in conflict-affected areas. The paper seek to assess how armed conflict and violence affect the health and education of children living in conflict areas. More specifically, this research looks into the anthropometric indicators that would suggest disruptions on the nutritional intakes, academic performance, and schooling of children. In doing so, the study evaluates the current status of health and education of children living amid conflict and violence, and compares the nutritional outcomes and academic performance of children from armed conflict areas to non-armed conflict areas.

Collective Bargaining Essay -- Labor Unions

Collective Bargaining Unions provide a vital service for employees and management by negotiating contracts, ensuring workplace safety, and representing employees in grievance hearings. While there are hundreds of unions in the United States, this paper focuses on three major unions, the National Treasury Employees Union (NTEU), the American Federation of State, County, and Municipal Employees (AFSCME), and the American Federation of Teachers (AFT). Furthermore, this paper will compare and contrast these agencies, summarize their roles in optimizing employee relations with organizations, describe four challenges management and union officials face, and evaluate privatization as a means of breaking public employee unions. Compare and Contrast Three Unions The NTEU started in 1938 as the National Association of Employees of Collectors of the Internal Revenue (NAECIR) to reflect their expanded membership they changed their name to NTEU in 1973 (History of NTEU, n.d.). The NTEU is an independent organization whose mission is "to organize federal employees to work together to ensure that every federal employee is treated with dignity" (Who We Are, n.d.). While the AFSCME started in 1932, in response to the depression and out fear of the reestablishment of the spoils system their mission "to promote, defend, and enhance the civil service system" (AFSCME: 75 Years of History, n.d.). Whereas the AFT started in 1916 Chicago as part of their mission, they sought to increase wages for all members including women and minorities (AFT History, n.d.).

Silk - The Queen of Fibers Essay -- Textiles

Silk, sometimes affectionately referred to as the â€Å"queen of fibers,† is the strongest natural fiber in the world, and it is used to make expensive cloth. There’s more to silk, though, than being great to make fine garments. Did you know that a thread of silk can be stronger than some kinds of steel? Probably not. We hope to give you more insight into the wonders of silk in our report. THE DISCOVERY OF SILK One of the only – if not the only – documentation on the discovery of silk is an ancient Chinese legend. According to this legend, silk was discovered in the garden of Emperor Huangdi around 2700 B.C.E. The mulberry trees in his garden were being destroyed, and he ordered his wife, Xilingshi, to go out there and see what was the cause of the damage done to his trees. When Xilingshi went out to examine the trees, she found white worms eating the leaves of the mulberry leaves and spinning shiny cocoons. She then accidentally dropped one of the cocoons into some hot water. And when she started playing with the cocoon in the water, long white strings disentangled themselves from the cocoon. It is said that this was how silk was discovered. Xilingshi then went to Emperor Huangdi to ask him to give her a grove of mulberry trees, in order for her to breed thousands of worms that would spin these beautiful cocoons. The king then obliged. Some accounts claim that she was the person who invented the silk reel, which is a device used to join fine silk filaments into a thread thick enough to be used for weaving. Others also credit her for being the maker of the first silk loom. How true these stories are still remain uncertain with historians. One thing they are sure about, though, is that silk was first used in China. The Ch... ...pired designs (like leaves or cherry blossom trees) or of animals (like dragons or phoenixes).

Report of Quantitative Research Essay -- Research Analysis

EL (English Learners) students are given an added challenge of succeeding in the education system do to their lack of strong English understanding and abilities. Authors Townsend, D. and Collins, P. published the findings of their research on EL students and the advantages of a specialized learning program. Over a period of several months, the researchers studied and worked with students from a middle school in southern California. At the end of the study, it was hoped that their efforts would lead to an improvement in the students who participated in the programs understanding of English vocabulary words. Research Questions/Hypotheses No specific hypothesis is noted, but the researchers do address the issues that drive the study. They state that the current study is concerned with, â€Å"applying evidence-based strategies in a new context: adolescent EL students learning general academic vocabulary words† (Townsend and Collins, 2009, p.997). The study also addresses, â€Å"the extent to which there is a threshold of English proficiency necessary for students to learn general academic vocabulary words† (Townsend and Collins, 2009, p. 997). These issues are addressed by the following research question: 1. Can an after-school, evidence-based academic vocabulary development intervention increase the academic vocabulary knowledge of middle school EL? 2. To what extent does English learners’ proficiency in English mediate their response to a vocabulary development intervention? It was hoped by studying a group of middle school students over a period that they would see growth in those student who participated in a program designed to add English vocabulary comprehension to their academic development would help them as EL students. T... ...s a great need to continue and accelerate the research and instructional efforts to support the academic literacy development of adolescent EL students† (p. 1015). A study that incorporates greater elements of vocabulary, reading comprehension, and time, is perceived to be needed in order to improve EL learner’s education. Townsend and Collins believe that there research can lead to much needed further research and that this can in turn help EL students achieve in a greater educational level. Works Cited Gay, L.

Intolerance from The Crucible Essay

Ayn Rand once said â€Å"A single lie destroys a whole reputation of integrity. It means that a lie sadly has enough power to cause corruption in a society. It also suggests that a lie perhaps be strong enough to destroy even a high ranking person from a society. If you tolerate lies dominating people around you, you’ll eventually be a victim of them. Two literature works that explain this quote are Author Miller’s play, The Crucible, which takes place in a Puritan town named Salem in the state of Massachusetts during the year of 1692. The Crucible shows how intolerance corrupts the town. And Maurice Ogden’s Poem, â€Å"The Hangman,† which takes place in an unnamed town. â€Å"The Hangman† shows how the ignorance of the townsfolk gives a pathway to the Hangman which enabled to execute every single one of the townsfolk on his gallows-tree. Meanwhile intolerance also takes place in â€Å"The Hangman† which makes the Hangman has no mercy for people who questioning him. Both literatures works The Crucible and â€Å"The Hangman† have Intolerance as one of the main themes in common. Intolerance takes place in â€Å"The Hangman†. The Hangman gives the townsfolk a severe test, which is the hang trial and see how the townsfolk will address it. The Hangman nervously arrives in the reader’s unnamed town, and built his frame. The town folks are wondering who the criminal is and what the crimes are. On the very first day he hanged a man who came from another land. The townsfolk who gathered in the courthouse square, leaves without saying anything because they don’t care for the foreigner. The townsfolk believed that the frame would be gone by the next day, but it didn’t because they neglected the first hanging. Now the Hangman doesn’t even bother to do so, because the townsfolk showed him they don’t really care. For the reason of that, the townsfolk become such easy targets for the hangman, because of his intolerant attitude. And we wondered, whenever we had the time, Who the criminal, what the crime That the Hangman judged with the yellow twist of knotted hemp in his busy fist. And he stepped down, and laid his hand on a man who came from another land. And we breathed again, for another’s grief At the Hangman’s hand was our relief Maurice Ogden Later on The Hangman executed an infidel Jew, then a dark skin one, both lived in the town. The Hangman’s intolerant personality combined with the townsfolk ignorance lead the hangman to executing the townsfolk in a large amount, which happens clearly because of ignorance. Those who wander why were hanged. This causes the town’s residents to become fearful. Then more and more were hanging. Finally even the speaker of the poem was hanged because of his ignorant personality. This means anyone who neglect either a party or someone dominate them will eventually suffer of it. The presence of intolerance in â€Å"The Hangman† is something that the town’s resident should be motivated to take away from the Hangman, unfortunately they was unable to do that cause of their fears and the Hangman’s intolerant test. â€Å"Dead!† I answered, and amiably â€Å"Murdered,† the Hangman corrected me. â€Å"First the alien then the Jew. I did no more than you let me do.† Beneath the beam that blocked the sky none before stood so alone as I. The Hangman then strapped me†¦with no voice there to cry â€Å"Stay!† for me in the empty square. Maurice Ogden Intolerance takes place in The Crucible It all began with a Negro slave named Tituba, combined with a group of daft girls goes dancing in the forest. In a Puritan town, anything that’s look unfamiliar to the Bible consider as something against it. While dancing in the forest, the girls ironically caught, by the town’s minister, Reverend Parris. On the following morning both Parris’s and the Putnam’s daughter were unable to wake up. The Villagers gathers at the minister’s house and quickly witchcraft rumor invade the town. Abigail what was a part of the girls dancing and who is Parris’s niece, warns the others girls to not to admit what they were doing in the forest. She even menace them she could kill them if they do so. Parris is paranoid; he believes that his congregation should not lift a finger without his permission when church is in motion. He thinks of nothing to do but to put his slave under pressure, because he think that Totuba might do witchcraft on his daughter, Tituba says to Parris â€Å"My Betty be hearty soon.† (Miller 8) This quotation shows that Intolerance has taken place in The Crucible Because Parris is don’t want his daughter to die, questioning and punishing Tituba is a good way to be aware of what actually happened in the forest. Another way in which intolerance has taken place in The Crucible is when Tituba fearfully accuses several town folks of reading the devil book. Abigail joins her revealing that she has seen many women with the devil. Betty and the other girls joining them as well, and they start pointing their finger on people. Abigail says â€Å"I want to open myself. I want the light of God, I want the sweet love of Jesus! I kiss his hand. I saw Good with the Devil! I saw Goody Osborn with the devil! I saw Bishop with the Devil.† (Miller 48) This quotation tells that she is showing the villagers that she want to be a better Puritan, she want to show the authorities that she is not a witch indeed she is. All of her accusers were hanged by the end of the story, Except Sarah Good who confessed right away. The fact that they hanged the accusers shows zero tolerance for witchcraft, they hanged the accusers because a puritan society does not tolerate witchcraft and that morality is obviously tradi tional. Another way in which intolerance has taking place in The Crucible is when Abigail who had an affair with John Proctor profits the witch trial occasion to accuse John’s wife of witchcraft so she could win it all. When Elizabeth name had been called in court john reveal that He had an affair with Abigail to test John’s claim judge Danforth approached Elizabeth and ask her if Proctor had been unfaithful to her, she lies to Proctor’s honor and judge Danforth denounces Proctor as a liar. Abigail herself forced Proctor’s servant to accuse him of being a witch, and she who is already afraid of her does so. Proctor says to Mary Warren â€Å"Do that which is good and, no harm shall come to thee.†(Miller 95) This quotation shows how Proctor is praying his servant to tell the truth; although she has great conscious she doesn’t do so because she is afraid that Abigail can attack her in her sleep. Proctor is rages not only against the court but also her, and now proctor is arrested. This suggest intolerance because, if intolerance wasn’t present they would have listen to Proctor’s argument too which have great integrity in the town, but because of intolerance they’ll hang him as any other accusers if he do not confess of witchcraft. In brief, both the poem, and the play speaks of intolerance, although â€Å"The Hangman† is mostly based on ignorance. It’s clearly has shown by the beginning of the poem that the townsfolk shows that they would not tolerate the Hangman to kill anybody in the town, but furthermore they ignore the Hangman, which they shouldn’t do because the greatest ignorance is to reject something you don’t know. They play, The Crucible shows that Salem won’t corrupt if there was tolerance, unfortunately it does, and later on the Judges discovered that they weren’t doing the correct thing but it was way too late due to the number on people died.

Consumer Behavior Case Study Do Our Avatars Learn Essay

1) According to the text, classical conditioning occurs when a stimulus that elicits a response is paired with another stimulus that initially does not elicit a response on its own. As time passes, the second stimulus is able to cause a similar response because of the fact that we associate it with the first stimulus. An example of classical conditioning would be one that was demonstrated by Russian physiologist Ivan Pavlov. He conducted research on digestion in dogs. Pavlov was able to induce classically conditioned learning when he paired a neutral stimulus (a bell) with a stimulus that was known to cause a salivation response in dogs (he squirted dried meat powder into their mouths). The powder represented an unconditioned stimulus due to the fact that it was naturally capable of causing the response. As time passed, the bell represented a conditioned stimulus. Initially, the bell didn’t cause salivation. However, the dogs learned to associate it with the meat powder and began to salivate at the sound of the bell only. The drooling of these canine consumers because of a sound, now linked to feeding time, represented a conditioned response. Pavlov demonstrated a basic form of classical conditioning that primarily applies to the responses that the autonomic (e.g., salivation) and nervous (e.g., eye blink) systems control. Meaning, it focuses on visual and olfactory cues that induce hunger, thirst, and other basic drives. When marketers are able to consistently pair these cues with conditioned stimuli, such as brand names, consumers may learn to feel hungry or thirsty when they encounter these brand cues at a later point. This is an example of how classical conditioning can operate for a consumer who visits a new tutoring Web site and is greeted by the Web site’s avatar who resembles Albert Einstein. The individual might not pick of the olfactory cues the first time he visits the Web site, but over a period of time he/she will. 2) According to an online source, instrumental conditioning (also known as operant conditioning) is a form of learning in which an individual modifies the occurrence and form of its own behavior due to the consequences of the behavior. The difference between instrumental conditioning and classical conditioning is that instrumental conditioning deals with the modification of â€Å"voluntary behavior† or operant behavior. Operant behavior â€Å"operates† on the environment and is maintained by its consequences. On the other hand, classical conditioning deals with the conditioning of reflexive behaviors which are elicited by antecedent conditions. Behaviors that are conditioned via a classical conditioning procedure are not maintained by consequences. This is a learning process that we most closely associate with the psychologist B.F. Skinner. Skinner demonstrated the effects of instrumental conditioning by teaching pigeons and other animals to dance, play Ping-Pong, and perform other activities when he systematically rewarded them for desired behaviors. Due to the fact that responses in classical conditioning are involuntary and fairly simple, we make those in instrumental conditioning deliberately to obtain a goal, and these may be more complex. The desired behavior might be learned over a period of time as a shaping process rewards our intermediate actions. From all of this research about instrumental conditioning, we conclude that a consumer who purchases a new outfit for his avatar on a virtual world would be modifying the occurrence and form of the avatar’s behavior due to the consequences of the behavior. 3)I believe that consumers do build associative networks through their avatar’s experience just as they would with any other product or service. The text states that we each have organized systems of concepts that relate to brands, manufacturers, and stores stored in our memories. The contents, however, depend on our own unique experiences. We should think of these knowledge structures, or storage units, as complex spider webs filled with pieces of data. Any information that is incoming gets put into nodes that connect to one another. When separate pieces of information are viewed as similar, we chunk them together under some more abstract category. Then, we are able to interpret new, incoming information to be consistent with the structure we just created. This helps to explain why we are better able to remember brands or stores that we believe â€Å"go together.† Recent research has indicated that people can recall brands that are not as obviously linked. However, in these cases, marketers have to work harder to justify why the two things go together. I do believe that this network is part of the consumer’s overall associative network for that brand. This is because in the associative network, links form between nodes. For instance, the text states that a consumer might have a network for â€Å"perfumes.† Each node correlates to a concept related to the category. This can be an attribute, a specific brand, or a related product. When the consumer is asked to list perfumes, she only recalls those brands that show up in the appropriate category.

Analysis of newton’s second law lab

Law Lab The first lab we did for chapter 4, Newton's Second Law, dealt with the relationships between force, acceleration, and mass. Our goal was to verify Newton's Second Law that says force is equal to the mass multiplied by the acceleration. Our procedures included setting up the lab according to the directions and collecting data as someone moved the cart that we set up forward and backward in two settings – with additional mass and without additional mass.For the part where we had to attach mass, we observed that the mass can be rotated sideways as we did our data collecting, so we decided to fix its position with tape, which did not affect the significant digits of the mass. After we were done with both trials, we showed linear relationships for both the force vs†¦ Acceleration graphs. In our first trial, we had a . 629 keg cart and an equation of F=O. AAA+O. 1289; in our second trial, we had a 1 . 143 keg cart with the added mass and an equation of F=l . AAA-1. 075 . In the equations, F represented force and a represented acceleration.We observed in the equations that he slope of the graphs were equal to, ignoring the insignificant digits, the mass of the cart used in the corresponding trials. The data were viable; the observations that we had made perfect sense to us since we knew that force is equal to mass times acceleration. The y-intercept, however, was unexpected; y Intercepts were not present in the second law of Newton. The Increased/decreased force then, I presumed, must have been caused by discrepancies made from minor friction caused by the wheel of the cart. Experiments regarding these y-landscapes should also be Interesting future experiments.

Guidelines for a Reflective Paper

In reality, it Is a lifestyle of Its own – something some people view as Hellenizing and patriotic while some view as terrifying and unacceptable. Some people are incredibly proud of a family member having served or have given his/her life to service; while some feel remorseful for having lost a loved one in war. However you look at it, military service is like a pendulum. It goes back and forth; left and right; liked or disliked; loved and hated; patriotic or horrific.To get to the point, every member of a military family is affected by the demands of the military; husband, wife, children, and even extended families such as grandparents, uncles and aunts. Additionally, every aspect of life Is also affected by the military -? marriage, schooling, religious practices, cultural, moral, social, and economic. Perhaps, the children represent a great percentage of the affected population. They are the silent majority – since they can't protest and need to get along with the f low of the rigid military life.My Life Before Who really knows what life Is Like for the children In the military? How do they cope with the separations due to deployments, changes In schools, leaving their friends Enid, starting a new social circle someplace In the world, divorce, culture shocks, language barriers, and career choices? No one would know better but a child who grew up wrapped around the military tight grip. I was one of these children. We are referred to as military brats; a moniker I am not really crazy about. But the military was my life for _ years. I learned to love it and hate it.I learned to appreciate it and loathe It. Learned to live It. And I found out that kids on the other side of the world (non-military) have Just as much If not more reasons to love and hate their life. I am not going to draw comparisons and contrasts between the two sectors but I would like to focus on how the military life has affected me as a person that I am now. How did it influence my philosophy in life? What did I experience out there that helped me mold my character? How did the military drive my energy and resources (in spite of Its straining demands) so I could look at the positives and build on them?

Credit risk management of CDSs, case from AIG Essay

Credit risk management of CDSs, case from AIG - Essay Example In regard to the bailout, AIG was presented with access to a $85 billion credit facility. In exchange, the United States government was presented with warrants for a 79.9% equity stake in AIG and the power to expel dividend payments to shareholders. AIG’s misfortunes started in a unit known as AIG Financial Products, which traded in credit default swap (CDS). A CDS acts as a safeguard against a default on assets that are connected to corporate debt and mortgage securities. The losses to AIG’s portfolio of CDSs were prompted by the disintegration of the subprime mortgage1 market. A groundbreaking amount of defaults by subprime borrowers with adjustable rate mortgages initiated the current catastrophe in the global financial markets in 2008. Most of these began in 2005 and 2006 when lenders remarkably loosened up on underwriting standards. Figure 4.2: Subprime mortgage originations Source: Bradford (2008) ‘The Subprime Mortgage Meltdown, the Global CreditCrisis and the D&O Market.’ Advisen : Productivity&insight for insurance professionals. The assumption was that homeowners would refinance prior to the monthly payments being readjusted, but decreasing real estate prices made it inaccessible for the majority of subprime borrowers who had hardly any or no equity in their houses to refinance. As they were incapable of paying the increased monthly payments, many borrowers had no choice but to default. Defaults in U.S. mortgages rose beyond record levels in the second quarter of 2007, and the fallout rapidly expanded all through the financial markets. The subprime mortgage debacle immediately brought forth the worldwide credit crisis. AIG is one of the financial institutions with credit default swaps business that was also affected during these circumstances. From then on, many CDSs were sold as insurance to cover those exotic financial instruments that created and spread the subprime housing crisis. As those mortgage-backed securities2 and collateralized debt obligations3 became more or less valueless, abruptly that reputedly low risk event saw an actual bond default occurring on a daily basis. AIG sold CDSs were no longer taking in free cash. It had to pay out a large amount of money. The crisis at AIG is a â€Å"question of liquidity, not of capital†, according to ROB Schimek, EVP and CFO of AIG Property Casualty Group. Despite the fact that there have been a small amount of losses paid under the CDSs, contract provisions demand of AIG to post collateral in cash if the value of the assets underlying a CDS declines. At the parent level, AIG has approximately $80 billion in shareholder equity, though the majority of that is secured in the company’s insurance operations and cannot be converted to meet the collateral calls of the financial products unit. Since it did not have enough cash to meet the collateral demands, the company faced a liquidity crisis and bankruptcy protection. 4.3 What AIG actual did leaded the company go down 4.3.1 The undoing of AIG liquidity crisis AIG reported â€Å"an unrealized market valuation loss of $11.5 billion on [the] super senior credit default swap (CDS) portfolio† held by its subsidiary, AIG Financial Products in the annual report for 2007. The definition of CDSs was discussed in chapter 2.2. This initiated a drastic downfall and ended AIG’

The Athlete's Shack Wireless Upgrade Term Paper

The Athlete's Shack Wireless Upgrade - Term Paper Example 2 Assessment For catering the needs of the business for TAS, there is a requirement of secure and effective wireless network connectivity for all the 10 stores within the same area. There are no requirements for establishing connectivity on long distant stores. However, security is a primary concern, as data channels will be established in the environment. For addressing the security issue, Cisco provides rich features and adds an extra layer of security on the wireless networks. The embedded security technologies on a wireless architecture are now standardized, as they are available by default in all vendor manufactured wireless devices. Some of these technologies are WEP, WPA etc. Moreover, after securing the data in transit by encryption, we have also proposed a wireless intrusion prevention system that will continuously monitor and prevent the network from cyber threats. However, there is no guarantee of the network security, if the iPads are misused and stolen or snatched from o ne of the employees of TAS. For addressing human threats, acceptable use policy and password policies will be implemented. 3 Solution As the TAS environment requires wireless connectivity, ‘access points’ are required. ‘Access points’ are the device which is used to connect devices equipped with wireless technology. ‘Access points’ transmits and receive radio signals adjacent to a network hub over a limited distance. However, distant varies from different model types and wireless technology adopted. The TAS requirement is to provide access of network resources to the staff for connecting the iPads. Cisco delivers a borderless mobility experience which gives users access to the information and resources with the quality and performance. 3.1 Wireless connectivity of TAS sites TAS haw 10 stores within the same area, and there is no information regarding the distance of each of these sites with each other. When designing a wireless point to point c onnectivity, the distance is always considered due to limitation of wireless technology. Cost is also a major factor when implementing and designing a wireless network. There are two methodologies which can be adopted for connecting all 10 sites to provide Internet connectivity. 3.1.1 Wi-Fi 802.11/y It is a relatively new wireless standard defined by IEEE 802.11 standards with more enhanced capabilities as compared to 802.11n. It operates on 3.6 to 3.7 GHz on 54 Mbps with the distance of 3 miles (Parsons & Oja, 2009). The distance which is required to connect all of these 10 sites can be achieved by connecting via 802.11y Wi-Fi technology. However this technology is currently available only in United States of America. The hardware which is required to connect all these 10 sites is relatively of low cost. This is a low cost solution but it has certain limitations as it is available only in the United States. There are very few IEEE 802.11y complaint devices available. The router can be installed at any one end of either side to broadcast the signals

Benchmark Analysis Comparing the AMD 910e and Intel 2400s Processors Essay

Benchmark Analysis Comparing the AMD 910e and Intel 2400s Processors - Essay Example For example, businesses require processors with appropriate architecture that will allow a maximum use of their IT environment, yet stable at the same time (Moore p. 169). For this paper, two of the stiffest competitors in microprocessor manufacturing will be featured: Intel with its Core i5-2400S, and; AMD’s Phenom II X4 910e. These processors were launched in the market in 2011 January and 2010 January, respectively. Table 1 shows the comparative specifications of these two processors. The Benchmarks and their Analysis A. Integer Math Test This test measures the speed and capacity of a processor to perform mathematical non-fractional numbers operations by using random 32-bit and 64-bit integers for basic mathematical operations such as addition, subtraction, division and multiplication at integer buffers of 240kb per core (CPU Benchmark 2010). Intel Core i5-2400S: 28456 MHz AMD 910e: 18925 MHz In the above stats, Intel Core i5-2400S was tested using AIDA64-CPU Queen, which p erforms a high memory read/write traffic and therefore not ideal for more than a single thread system because of the possibility of creating a bottleneck leading to low scores (Vortez2011). AMD 910e was tested using the Everest Ultimate Edition (higher is better), using Vincent Rijmen, Antoon Bosselaers and Pablo Barreto’s public domain C code in ECB mode, which uses 48MB memory and fundamental x36 instructions (Wu 2010, p. 7). B. Compression Test Using memory buffers of 16kb per core, the compression test gauges how fast a processor can compress large blocks of data into smaller ones without any original data being lost in the process. The ability to compress is an important function in software application. The result of this test is in kb/second (CPU Benchmark 2010). Intel Core i5-2400S: 125 kb/sec AMD 910e: 133 kb/sec Intel Core i5-2400S was tested using the WinRAR 4.0 utility (Gavrichenkov 2011, p.4) while the AMD was tested using the WinRar Workload utility where data i s randomly generated containing deliberately introduced redundancy to increase the load in the CPU and memory. The algorithm then compresses and decompresses the data (Wu p. 5). C. Prime Number Test The Prime Number Test gauges the speed of the processor in searching for prime numbers or numbers that are divisible only by 1 and by itself such as the numbers 1, 2, 3, 5, 7 and 11. The algorithm used for this operation uses the same loops and operations that are standard in most computers without any memory buffer (CPU Benchmark 2010). D. Encryption Test This test gauges the speed of the computer to encrypt blocks of data, an operation employed by users to store data, which can be accessed only by the user with the encryption key. It uses the blowfish algorithm and shares many of the operations used in the math test except for the large binary data manipulation and mathematical operations such as ‘to the power of’ (CPU Benchmark 2010). Intel Core i5-2400S: 372733 (traditio nal DES) AMD 910e: 93.4 The Intel 2400S was tested with John the Ripper v1.7.8, which uses the blowfish algorithm (OpenBenchMarking 2011), while the AMD 910e was tested using TrueCrypt, which is an open-source encryption package. Two hundred MB was used to run the utility that gives back an AES-Twofish-Serpent mean score. E. Floating Point Math Test A similar test to the integer math test, the floating point test measures the speed of a processor to perform basic mathematical oper

Market Competitiveness for SOEs in China Essay

Market Competitiveness for SOEs in China - Essay Example However, in spite of its attractions and potential, Western businesses are still apprehensive about the business environment in China. Its huge population has resulted in unique problems for China. Thus, the government has had to adopt a very cautious approach to guide the country towards its future. One such assiduous yet formidable step towards reassuring the world community about the intentions of Chinese government is the Reforming of the ‘State Owned Enterprises’ (SOE). Despite China’s future potential, there are still some strict regulations, political interference, guanxi (a need for relationships to operate in the market) and low disposable incomes of the Chinese consumers. Hence, China’s recently opened market presents both challenges as well as opportunities for the foreign businesses. This dissertation examines the status of SOEs and recommends some positive steps to make these enterprises more competitive. Further, the author analyzes the effect of the removal of the excessive state cover over the business enterprises which pave the way for a competitive environment in China. Industries that provide better employment opportunities for the people and a reliable source of income for the poor have been established to reduce poverty and to achieve equitable and sustainable development. Therefore, it is imperative that the growth of labour-intensive industries be a central theme of development economics and policies. The proponents of liberalization and globalization claim that globalization has granted access to newer vistas of trade and business all around the globe. Interestingly, several theorists believe that the launching of these economies have tilted the balance in favour of market forces. This is no doubt helping the consumer by way of providing quality at reasonable prices but at the same time the profit motive is leading to some aberrations where the welfare measures

Human Resource Management has evolved significantly over recent Assignment

Human Resource Management has evolved significantly over recent decades with an increasing emphasis on contributing to business - Assignment Example The introduction of globalization and the subsequent growth of cross cultural business made a further name change in the employee management department. Now, instead of HRM, Strategic HRM is prominent in the organizational world. Employees are the backbone of any organization. Even though an organization has many other resources, human resources are the most important ones. All the other organizational resources such as machines, money and materials, need the supervision from human resources for proper utilization or mobilization. This paper evaluates different approaches in strategic human resource management (SHRM) and describes the positioning of SHRM in contemporary context. Introduction According to Bratton & Gold (2012), â€Å"Labour is not a commodity. It is people in work organizations who sets overall strategies and goals, design work systems, produce goods and services, monitor quality, allocate financial resources and market the product and services† (p.8). Even tho ugh an organization has many internal and external resources, none of them has the ability to act independently except the human resources. In other words, all the organizational resources can be mobilized properly only under the control of human resources. There is nothing wrong in saying that HR can make or break an organization. Boddy (2008) defines Human Resource Management (HRM) as â€Å"the effective use of human resources in order to enhance organizational performance† (p.354). Because of globalization, majority of the prominent companies are currently operating cross culturally. Outsourcing and offshoring like modern business principles were evolved out as a result of globalization. Exploitation of cheap labor is vital for an organization for staying competitive in the market. Moreover, diverse workforce is common in most of the modern organizations. Management of diverse workforce necessitates restructuring or modifications of many of the existing HRM principles. Ins tead of HRM, SHRM is common in most of the modern organizations. According to Bratton (N.d.), â€Å"Strategic human resource management is the process of linking the human resource function with the strategic objectives of the organization in order to improve performance†(p.37). The ability to stay competitive determines the success and failures of modern organizations. The way of doing business in the past and present are entirely different. SHRM helps organizations to formulate strategies suitable for the changing principles in the organizational world. Different approaches and models are prevailing in the organizational world with respect to the implementation of SHRM. Different approaches in strategic human resource management (SHRM) According to Bratton (N.d.), â€Å"Strategic HRM’ is an outcome: ‘as organizational systems designed to achieve sustainable competitive advantage through people’† (p.46). For example, plenty of American companies ar e currently struggling in international market, not because of the poor quality of the products they produced, but because of the huge price of these products compared to the prices of products from competitors. It should not be forgotten that America is a country in which manpower cost is extremely high. On the other hand, China and India are countries in which manpower cost is extremely low. Nobody has any doubt about the technological dominance of American companies. However, expensive labor preventing American companies from competing effectively in the global market. Currently,

Drop Out of School Essay Example for Free

Drop Out of School Essay Today many young people do not realize the importance of an education so dropping out of school becomes an option. They just easily end up dropping from school without thinking about their future. They are thinking that their parents will support their financial daily lives, thus they do not feel worried about continuing their education. Moreover, there are several reasons that make young people decide to drop out of school some of which are getting poor grades, not getting along with teachers and/or students, or having a drug or alcohol problem. Those reasons make the young people end up by dropping from school. However, if the parent has been guiding their children well, they may be able to be solving the problem. There are no easy solutions to the school dropout problems. However, here are two ways to solve these problems; parents should encourage their children to do the right things and parent should meet with the school counselor. There are some solutions to the problem of dropping out of school. First, parents should encourage their children to do the right things, so that one day the children will become a better person and will be useful for the childrens future. For example, parents should talk with their children about how important the education is for their future; help them understand that the choices they make can seriously disrupt their future. The parent should not give up trying to make conversation with their children. Furthermore, the parent should start a conversation by asking their children how school is doing or make other conversation where both side feels comfortable with each other. In addition, by being open to one and another would give the children confident to talk about what they have been observed from school. This type of communication is sometimes hard to do but it is necessary to keep their children remain in school. Next, when a parent notices that their children want to drop out from school, the parents should follow this solution: workings with school counselors or teachers that can help their children remain in school. For instance, the parent may arrange for help by making up a schedule to meet the school counselor. The parent has to inform their children to meet with their school  counselor at least once a week to solve their children problems in the school. Especially, for children who has a problem in certain subjects which make them to think about dropping out of school. As an expert, the counselor will give advice to the young people by explaining how important education is for them on the future. Moreover, education is one of the requirements to get a better job, which they will later need for their future and for personal responsibilities. In conclusion there are many reasons why kids drop out of school. Primarily they have to do with a poor understanding of what good education is, struggling to make the grades, and due to drug problems. By maintaining good open communication with their children and seeking advices from school advisor which are preventing their children drop out from school. In the end, the parents and children can work together to keep the children remain in the school. Thus, by having good communication with their parents, teachers, or school advisor, it is important for children to realize that the adults in their lives do want them to remain in school and are willing to do a lot to make it possible. Hopefully, these tips might be helpful for parents who have problems with their children who want to drop out from school.

motivational and emotional factors help you to understand your own health and fitness Essay Example for Free

motivational and emotional factors help you to understand your own health and fitness Essay What were the motivational and environmental factors that contributed to the weight gain? The motivational factor that I belive Tasha had was prioritizing her children over her own health and the enviromental was that she had two children both at a hard age that needed her all the time witch took all the time, energy and focus. Briefly describe which approaches to motivation you feel best help us to understand the change in Tasha’s behavior. the best motivational aproach that I thought helped me understand it better was intrinsic motivation witch according to our textbook is â€Å"based on the personal satisfaction the person gets from doing the task† (Lefrancois, 2011) I choosed this because she was was being motivated by her mood and the way she feels about herself. In what ways was emotion tied to the weight gain and loss? Being tired and preocupied accounts for her weight gain and being unhappy with her weight and her mood motivated the loss. How might understanding these motivational and emotional factors help you to understand your own health and fitness? When I started reading this, I though I was reading about myself, this story has a lot to do with me. When I had my second child I gain 40 pounds I felt fat and everyone was telling me that I gain weight and I felt more discusted with myself, I hated my body and I was very unhappy with it. So one day I saw a friend of mine on facebook she had posted a picture of how she lost 30 pounds in 2 months and that got to me and I asked her how she did it and she put me in touch with the trainner that helped her. I got myself a personal trainner and started taking this product call YOR HEALTH and that has helped me loose 45 pounds and now I’m proud to say that I have the body I always dreamed of having and they want me as a model for a fitness magazine in witch im still debating because that is not my thing. By understanding these emotinal and motvational factors has helped me realize that what I did and been doing I did it all correctly. Will you change anything in your own life as a result of this scenario? I have to say as of right now I wouldn’t change anything because its something I’m doing now. Reference: R. Lefrancois (2011 ).

Why did you select it? How might this theory help us understand your character’s personality? I had a similar assigment in another class and I absolutly loved it because I got the chance to talk about my favorite character person and I absolutley love this lady her name is Madea known as Tyler Perry. She has been in manny movies all of of them has a been a great success. My favorite out of all her movies is â€Å"Witness Protection† in this movie she played a role of protecting a family that had to be under witness protection until a case was resolved in court. This family was not one of the best family not a close family but once they got to Madea’s house she made sure she tought them how to live with eachother as a family and tought them the real meaning and  importance of having a family there for you. I selected this character because in her movies she has inspired me and show me and everyone who watches her movie that no matter what family values is very important. One aprache that I choosed for her character is humanistics aproach because she would make sure you understand her world and where shes coming from for her to be able to get on you page. She has to get her point across and has to make sure everyone understands and follows what she says in a easy or a hard way just like out text boo stated â€Å"The self; worth, dignity, individuality† (Lefrancois, 2011) and â€Å"My perception of the world is real. So is yours. We have our separate realities. If we are to understand each other, you must try to understand my world, and I yours† (Lefrancois, 2011) I chosed this personality beucase and that is exactly how Madea is when shes trying to get a point across. She has all o those traits in her pesonality she shows her self her dignity and her individuality. If anybody in class has watch her movies can tell you how her personality is in manny ways I wished I had her same personality. Reference: R. Lefrancois (2011 ). Psychology: The human puzzle.

The Conservation Of Momentum Environmental Sciences Essay

The Conservation Of Momentum Environmental Sciences Essay The conservation of momentum was shown in three types of collisions, elastic, inelastic and explosive. By getting mass and velocities for two carts during the collision the change in momentum and kinetic energy was found. In an elastic collision of equal massess ΔP = Pf-Pi =-8.595 and ΔKE = KEf-Kei = -4.762. In an inelastic collision of equal massess ΔP = -12.989 and ΔKE = -43.14. In an explosive collision of equal massess ΔP = -448.038 and ΔKE = -118.211. This shows that conservation of momentum is conserved in elastic and inelastic equations due to their very low change in momentum; however kinetic energy is conserved in the elastic collision but not in the inelastic collision. In an explosive collision momentum is not conserved since the two objects start at rest with no momentum and gain momentum once moving opposite. Introduction Just like Newtons laws, the conservation of momentum is a fundamental principal in physics that is integral in daily life. However unlike Newtons laws, the conservation of momentum does not seem to be entirely intuitive. If a ball is thrown in the air some momentum seems to be loss to the air. This makes proving the conservation of momentum tricky and difficult to do in a real life setting. To measure the conservation of momentum in the lab, two carts will be used along a frictionless track. This allows calculation to be easier since the vectors will be moving along only one axis. This way positive direction can be movement to the right while negative direction can be movement to the left. One cart will have a plunger which is ejected by a spring that will convert its potential energy to kinetic energy of the cart. This will knock the other cart and its momentum will be transferred either partially or entirely. These velocities of the two carts will be measured by a graphing device. This is shown in diagram 1. Diagram 1. Momentum is produced by mass and velocity, in other words: p = mv. It is important to point out that momentum is not conserved on an object by object basis, however it is conserved for the isolated system. This is shown in the equation: Psystem = P1 + P2. Therefore if momentum is conserved then the initial momentum of the entire system should equal the final momentum of the entire system. Thus this can be shown in the equation where: Psystem, initial = Psystem, final M1 X V1i + M2 X V2i = M1 X V1f + M2 X V2f In the lab collisions will be shown to illustrate the conservation of momentum. In elastic collisions energy is always conserved. Unfortunately for this lab kinetic energy can be converted into heat so that energy is lost to viable measurements. If the energy is conserved, the collision is considered to be elastic, but if the energy is not conserved, then the collision is considered inelastic. Kinetic energy is energy associated with motion where an object with mass and moving with a certain velocity the equation is: KE = Â ½ m |v|2 This allows to find the loss or gain in energy of a system much like for momentum where the change in kinetic energy of a system is determined by the equation: ΔKESYS = KEsys,final KEsys,intial For the two collisions stated earlier if ΔKESYS is equal to zero the collision is considered elastic, however if ΔKESYS does not equal zero then the collision is considered inelastic. There is also another type of collision that will be determined in this lab called an explosive collision. This can be considered the opposite of an inelastic collision since the energy is not conserved because the kinetic energy is transformed for potential energy to kinetic energy. These three types of collisions will be measured in the lab under differing conditions and the change in momentum and kinetic energy of the system will be calculated. Procedure In the lab the momentum and kinetic energy will be calculated by measuring different velocities for the two carts at different masses. Two carts will be set along a frictionless track. As stated earlier this allows for easier calculations since it allows working only in one dimension. One of the carts used has a plunger while the other car is just a regular car. Both carts have different sides which will allow the emulation of the different collision types. For and elastic collision the plunger cart will be placed against the side of the ramp and then set off by a small piece of wood. It will the knock the other cart and emulate a elastic collision because the carts have magnets facing each other that will help conserve energy and momentum by having the opposite sides face each other. Having magnets of opposite charge face each other help keep the collision elastic since major contact between the two carts can convert kinetic energy into heat and will be lost. This will be done in three different ways, first having equal mass carts, second having the plunger cart heavier than the regular cart, and lastly by having the plunger cart lighter than the regular cart. The velocities for these carts will be measured for the different variable for six different trails and averaged. For the inelastic the set up will be identical except to emulate this collision the carts will have Velcro sides that will be facing each other and cause the carts to stick together once they hit each other. This will be done in three different ways similar to the elastic collision, first having equal mass carts, second having the plunger cart heavier than the regular cart, and lastly by having the plunger cart lighter than the regular cart. The velocities for these carts will be measured for the different variable for six different trails and averaged also. For the explosive collision the two carts will be sitting next to each other. The plunger car will have its plunger faced toward the adjacent regular car so when the button is pressed the will move away from each other in opposite directions. This will only be done in two different ways, one way having the carts equal in mass and one ways have one cart heavier than the other cart. The velocities for these carts will be measured for the different variable for six different trails and averaged as well. Results Table 1.

There is no initial momentum for this collision since the two carts started together at rest. Conclusion From momentum and the kinetic energies calculated from the formulas the different trails were averaged to find the initial and final momentum and kinetic energy for each of the eight conditions. They the change in momentum of the system was calculated for the system by subtracting the final momentum minus the initial momentum. This was then done for kinetic energy to find the change in kinetic energy by subtracting final minus initial as well. This produced different values for the different conditions. For the elastic collision the momentum and kinetic energy are supposed to be conserved. As table 1 shows, the momentum and kinetic energy for the equal mass carts is very close to zero, much closer than for the other conditions. For the heavier plunger cart, the initial force had much more inertia and caused the lighter second car to move much further. This is opposite in the other conditions where the plunger cart was much light. It had a harder time moving the second heavier cart. The main difference for the change in momentum and kinetic energy for the two unequal mass cart conditions was due to the fact the final velocity for cart one was never measured properly. It was assumed that the velocity was zero when in fact the plunger cart moved slightly after the collision. The assumption was due to careless human error. For the inelastic collision kinetic energy is not conserved. This is evident very much in the results for the change in kinetic energy. There is a much larger value or this change then in the elastic counterpart since the carts stick together and move as one unit. This close interaction allows for the loss of energy as heat. As for the explosive collision, the change in momentum is by far the largest. Since the system start at rest it is entirely potential energy. When the collision happened the carts move apart and become kinetic energy. Since the final momentum is subtracted by an initial momentum of zero, it is obvious why the change is so large.
