Male vs Female Crime Rates Essay

Statistics indicate that men are more likely to commit crime than women. For example, in 2002 80% of known offenders (481,000+) were men. As there are a number of problems with the reliability and validity of statistics, an alternative to information are self-report studies. These are anonymous and some believe because they all but guarantee anonymity they encourage respondents to be more truthful than if they were involved in an interview. In the past, sociologists tended to pay attention to only males committing crimes and ignored gender differences. This began to change in the 1970’s when feminists such as Carol Smart looked into woman and crime and began to ask questions such as: †¢ Why do woman commit fewer crimes than men? †¢ Why are woman more likely to commit to social norms compared to men? †¢ Is there anything distinctive about a woman’s experience as an offenders and as victims of crime? †¢ Are woman treated differently than men in the justice system? There is now an agreement within sociology that when studying crime and deviance we must take into account gender. This means we must also ask questions about men. What is the relationship between crime and masculinity? Sex role theory: this theory argues that boys and girls are socialized differently, therefore resulting in boys becoming more delinquent. There are different versions of this theory. Edwin Sutherland (1949) stated that there are clear gender differences when it comes to socialization. Firstly, girls are more supervised and more strictly controlled. Secondly, boys are encouraged to take risks and to be tough and aggressive. Therefore, boys have more of an opportunity and an inclination to commit crime. Talcott Parsons (1995) believes that there are clear and obvious gender roles within the nuclear family. The father performs roles which show him to be more of the leader and provider, whilst the mother performs the expressive role of giving emotional support and socializing children. These roles are rooted from the birth of their children as mothers have to give birth and nurse children. Girls have a readily available female role model at home (their mother) whereas boys have less access to their male role model as traditionally the father was out at work for most of the time. Boys will be socialized largely by their mother and will tend to reject behavior that is seen as feminine as they compulsively pursue masculinity. Because of the emphasis on toughness and aggression this encourages anti-social behavior and delinquency. Albert Cohen (1955) believed that if boys don’t have that readily available role model, socialization can be a difficult process. Boys can experience anxiety about their identity as a young man and a solution for this is all male peer groups or street gangs. In these social contexts, aspects of masculinity can be expressed and rewarded. The idea of being tough and breaking rules can help to conform to the idea of masculinity. The feminist perspectives on who is involved in crime starts from the view that society is patriarchal and woman can only be understood under male dominance. Pat Carlen (1990) stated that a woman’s crimes can be known as ‘the crimes of the powerless’ as many woman who commit crimes are powerless in some way. For example, they live in poverty with little power to change the situation; as children they may have been badly treated and looked after, perhaps being abused by fathers. As adults they have often lived under the dominance of male partners who asserted control – perhaps in the form of violence. After interviews with 39 woman aged 15 to 46 convicted of various offences, Carlen drew on the control theory – saying that woman turn to crime when the disadvantages outweigh the advantages. It appeared that the interviewed women turned to crime as a rational choice. Low paid work and unemployment had not led to the standard of living they hoped for, and living an unhappy life as children and as adults was very unfulfilling. Unrewarded by family and the workplace and with little power to change the situation, crime was a rational alternative. However, critics of Carlen claim that her sample of woman was too small to make generalized statements. Her research also suggests that conformity to social norms tends to break down when the rewards for doing so are absent. Conformity and control: According to Frances Heidensohn the striking thing about woman’s behaviour is their conformity to social norms. Taking in mind the control theory, women have more to lose than men if they deviate from social norms. And looking from a feminist view, she argues that in a male-dominated society the control of woman by men discourages deviance from norms. In the home and family, women still have the primary responsibility for raising children and taking on the domestic work. Their commitment to this also means they are committing to the conformity of the traditional mother-housewife role and socializing their children in terms of society’s norms and values. Women have been socialized to conform. Girls are more strictly supervised and given less freedom, they are expected to perform household duties. These expectations and control have been carried on into adult life. As adults, women are not only controlled by their childhood socialization but also by their male partners. Woman who challenge these traditional roles are often brought into line by men’s financial and physical power. According to Heidensohn, wife battering is an assertion of patriarchal authority. Women’s socialization, domestic responsibilities plus the control imposed on them by men discourage the deviance from social norms. Their lives are centered on the home so they have less freedom to go out. As a result they have less inclination, less time and fewer opportunities to commit crime. Beyond the home a woman’s freedom to deviate from social norms is also limited in a number of ways; for example, some women do not want to go out after dark as they are in fear of getting attacked or raped by men. A young woman’s fear of being attacked by a stranger is five times greater than a young male’s. They are also less likely to deviate from norms of respectability for fear of being labeled promiscuous. In a working environment men are more likely than women to be in control, in positions such as supervisory or managerial roles, and surveys indicate that sexual harassment is common in the workplace and it is a further indication of male power and control which is often experienced as intimidating by women. Both inside and outside the home, there is pressure for woman to conform- and this is reinforced by male power. Crime and masculinities: Research into gender over the last 25 years has mainly been concerned with woman and crime as it was seen as a new topic after decades of research into men and crime. Feminists would focus on woman and men would enter the equation in terms of the control men had over woman. Researchers now recognize that there is another side to gender and crime and start to ask questions such as: Why are men more likely to commit crime than woman? And is there a relationship between male crime and masculinity? Gender identity is a vital part of the individual’s sense of self – it is something that people accomplish. People are continuously trying to express and present their masculinity or femininity. And in relation to crime, you can say men commit crime as a means of constructing this masculinity to express to others and themselves. There are a number of different masculinities which are shaped by social class, ethnicity, age and sexual orientation. Men’s position in society provides them with different access to power and resources which leads to different constructions and expressions of masculinity – and this leads to different types of crime. The most dominant form of masculinity is known as hegemonic masculinity. It’s the most ideal form, which is defined through work in paid labour, the subordination of women, heterosexism and the uncontrollable sexuality of men. Most men wish to accomplish this. The alternative is subordinated masculinities. They include masculinities which develop in some ethnic minority and lower class groups and homosexual masculinity. Young middle-class white males are usually able to demonstrate some of the characteristics of hegemonic masculinity through success at school or college. But this comes at a price – subordination to teachers. Some assert their masculinity outside of school through vandalism, petty theft and heavy drinking. White working- class males are less likely to be successful in education. They sometimes resist school and construct their masculinity around physical aggression, anti-social behaviour, delinquency and some cases violence towards gays and members of ethnic minority groups. Lower working class men from ethnic minority groups with little expectation of educational success or secure employment sometimes assert their masculinity in street gangs. With little chance of accomplishing hegemonic masculinity by legitimate means, they are more likely to turn to robbery and serious property crime. Even middle class males who have the resources to accomplish hegemonic masculinity use crime to express masculinity. James Messerschmidt argues that white collar and corporate crime are not simply a means for profiting the individual or the organization. There are also a means of accomplishing hegemonic masculinity as a successful breadwinner and as an aggressive risk-taking male Working class crime in the workplace can also be seen as a means of accomplishing masculinity. Workers sometimes resist the authority of management by theft and industrial sabotage. Messerschmidt uses the example of African-Americans to illustrate a subordinated masculinity. Lower class African-Americans males often lack the resources to accomplish hegemonic masculinity. The pimp and hustler are long-established roles in African-American subculture and are often seen as an alternative to subordinated masculinity. The pimp looks after a number of prostitutes and lives of their earnings. With their expensive car, diamond rings and power over women, Messerschmidt argues that the pimp demonstrates a highly visible alternative masculinity to himself and others.

Strategic Planning, Learning Theory, and Training Needs Analysis

The five phases of the training process model include; Needs Analysis Phase; Design Phase; Development Phase; Implementation Phase, and the Evaluation Phase. The â€Å"Needs Analysis Phase† is to determine each employee’s needs and ask â€Å"What do we want our employees to get out of the program? † This phase will help identify the difference between comparing the company’s current results to the company’s â€Å"expected organizational performances. The performance gap is one way to figure out what is best needed in the training process of the company. Our text states that the â€Å"needs analysis phase begins when there is a performance problem within the organization. Examples of this problem might be: lack of quality, customer dissatisfaction, or reduced profits. If the identified problem is related to employee knowledge, skills, or attitudes, then a training need is indicated. † (Blanchard / Thacker, 2010) It is much less costly to have a gap analysis prepared; than to guess at what the needs are before the training objectives begin. The â€Å"Design Phase is where the needs of the â€Å"training objectives are created along with the factors needed to facilitate learning through content delivery. † This assessment of needs can be linked to the information and then used to â€Å"create the new curriculum of the program objectives. These provide specific direction for what will be trained and how. † The phase of design should allow us to begin to think about our â€Å"operational considerations to the program. We may ask ourselves how the delivery of the program is going to â€Å"influence the business operations† in the foreseeable future. (Blanchard / Thacker, 2010) The Development Phase is described as the â€Å"process of formulating an instructional strategy to meet a set of training objectives as well as obtaining or creating all the things that are needed to implement the training program. † In this stage the materials used can be movies, games, visual aids, etc. The trainer nee ds to be sure they keep the trainees fully engaged with activities to ensure the knowledge is retained. With updated materials and â€Å"revamping of statistical data† the trainee’s should be able to stay focused and interested in the program. (Blanchard / Thacker, 2010) In the Implementation Phase, â€Å"all the aspects of the training program come together,† and the training actually takes place. Some important things to keep in mind are what practices will be discussed; potential leadership skills; addressing classroom rules and class expectations required, and have on hand, a feedback form for the trainee’s to fill out at the end of the program. The Evaluation Phase consists of two types of evaluations. First, â€Å"the process evaluation determines how well a particular process achieved its objectives. † Like, â€Å"did the trainer follow the exact training process suggested? † Second, is the outcome evaluation, which is conducted at the end of the training to determine the effects of training on the trainee, the job, and the organization? † Furthermore, â€Å"if the outputs of the program were less than expected, then changes to the program may be necessary. Companies should establish a systematic evaluation process to enhance the effectiveness of the training. † The company really needs to determine, through the evaluation phase; whether the training enhanced employee’s performance or the company’s performance as expected. (Blanchard / Thacker, 2010) The end results focus on â€Å"both the evaluation process combined with the training unit and has a complete picture of the training from needs analysis to training techniques. It furnishes information about the trainer, and measures learner’s outcomes through reaction, learning, behavior, and results. (Blanchard / Thacker, 2010) Identify three factors that might inhibit HRD managers from developing a strategic planning approach to training. Recommend how these three factors might be overcome. Some factors that may inhibit a HRD manager from developing a strategic plan could be â€Å"the lack of motivation to participate in new learning tasks; a lack of funding available; a lack of clarity on the role of HRD; and perhaps not enough time available for new development in the company. †It is important for every Company in business to be aware of certain factors; in order to accomplish their goals successfully. Blanchard / Thacker, 2010) Overcoming some of these negative factors maybe the â€Å"HRD manager needs to ensure that their HR teams is open and committed to the highest training expectations that are available to every employee’s success. † (Blanchard / Thacker, 2010) The company should be totally â€Å"committed by financing the proper training that is needed for the future success of the company as a whole. † What a business puts into the investment of their employee’s, are most l ikely to surface motivated success for the company. The HRD should clearly clarify exactly what their role is going to entail, right from the start, so there will be full understanding of each employee’s expectations. The company needs to â€Å"dedicate sufficient amount of time each year for the proper training of its employee’s. † Dedication of the company is just as important as the employee’s dedicating their KSA to the company. Compare and contrast the behaviorist and the cognitive approaches to learning. Explain which is more relevant to training. Behaviorist approaches to learning usually are â€Å"focused on people who have specific observable behaviors or habits that they want to change. After understanding the principles of learning, they may even be able to modify their own behavior. † (Blanchard / Thacker, 2010) The Cognitive approaches are concerned with the â€Å"thought process; these people focus on changing the way they think. Our text explains that the cognitive approach suggests that the learner controls learning, and they may come to training with their own set of goals and priorities. † Whereas the behaviorist come to training with a specific goal and believe the â€Å"environment controls the learning outcome. (Blanchard / Thacker, 2010) The two definitely are different in ways, but â€Å"behavioral and cognitive approaches are being used in the same multimedia application. Both involve analysis, decomposition, and simplification of tasks in order to make instruction easier and more efficient† (Jonassen, 1991). Both use â€Å"devices to arouse, attract, and focus attention. Both force learner engagement through interactive decision-making points in the material. Both give importance to intrinsic feedback, though it may be expressed in voluntary help or advice option s in applications with cognitive design. Both value meaningful learning and realistic contexts for application of knowledge and skills† (Atkins, 1993). It is my opinion both are equally relevant to the training programs, depending on which approach one wants to take. Fully explain the purpose of a training needs analysis (TNA). Argue the conditions under which a TNA is always necessary, and offer two examples when a TNA might not be required. The purpose of a training needs analysis is to â€Å"close a gap between what the â€Å"actual organizational performances are and what the expected organizational performance should be. The TNA is represented as having a triggering event, an input stage, a process stage, and finally an output phase. † (Blanchard / Thacker, 2010) The input phase â€Å"consists of three levels of analysis; the organizational analysis focuses on organizational strategies, resources, resource allocation, and the internal environment. The analysis of the organization’s internal environment will help to identify the cause of the organizational performance gap, and will help to decide if training is the appropriate cure. (Blanchard / Thacker, 2010) The operational analysis â€Å"examines the specific jobs to determine and what KSA are necessary to get the job done. This process is known as job analysis, which is a detailed examination of all of the job tasks. Once the tasks are identified, then a decision can be made as to what KSAs are necessary to do the job competently. † (Blanchard / Thacker, 2010) The operational analysis â€Å"examines specific jobs to determine and what KSA are necessary to get the job done. This process is known as job analysis, and it is a very detailed examination of all of the job tasks. Once the tasks are identified, then a decision can be made as to what KSAs are necessary to do the job competently. † (Blanchard / Thacker, 2010) The person analysis; is the final stage that actually† focus on those in the job who are not meeting the performance requirements. Data on individual employees may come from a number of data sources, but the two most common sources are performance appraisals and efficiency tests. By incorporating the three levels of analysis, organizational, operational, and person, the identification of the performance gap should be complete. From here decisions can be made as to whether a training need or a non-training need has been identified. † (Blanchard / Thacker, 2010) The TNA is always necessary when the organization notices performance problems, because they need to know what the causes are, so they can be corrected in a timely manner. For most â€Å"training situations, use of the TNA will increase the relevance and effectiveness of the training. It ensures wise use of training funds, delivers the appropriate training to the right people, and contributes to the fulfillment of organizational goals. Diversity, language, retirement, and â€Å"turnovers are all factors that might contribute to a performance gap. † (Blanchard / Thacker, 2010) According to chapter 4 in our text; â€Å"TNA might not be necessary when an organization is trying to communicate a new vision or address a legal concern, which would include all employees to be present in the training program. † When the organization has d ecided to conduct â€Å"team building skills for a more positive performance outcome†; all employees will be trained in this case; there is no need for a TNA to be done.

Ralph Ellison’s “On Bird, Bird-Watching, and Jazz” Essay

Analysis on Ralph Ellison’s â€Å"On Bird, Bird-Watching, and Jazz† Ellison’s purpose in this essay is to prove that â€Å"Parker was a most inventive melodist-a true songster† which is evident in paragraph one. He uses the fascination of nicknames to symbolize the achievements of â€Å"Bird† and the impact the nickname had on others. He adds in a joke near the end of paragraph two, â€Å"why, during a period when most jazzmen were labeled â€Å"cats†, someone hung the bird on Charlie.† to show that even though most jazzmen were called â€Å"cats† at the time, Charles earned the name of â€Å"Bird† because he was above other jazzmen, like a bird would hang high above a cat so the cat couldn’t reach the bird. Charles’s talent was so above all the other â€Å"cats†; they couldn’t even reach his level. In paragraph three Ellison compares the goldfinch to Bird. He uses a short apocryphal story of baby Jesus being given a clay goldfinch for a toy and bringing it to life as a metaphor to indicate that Bird brings jazz music to life. The majority of paragraph three is Ellison going through the species of the goldfinch and how it is characterized, then at the end he hits the reader with the problem of why it does not relate to Bird; it’s like the canary. Paragraph four goes on to show the similarities the mockingbird has that connect it to Bird himself. The sentence structure in paragraph four mimics that of a saxophone holding a long, drawn out note. The sentences are long and drawn out, making the reader have to take a breath in between because the sentences are so long which would happen if a jazzman were playing the saxophone. He is connecting the sound of a saxophone to the sentence structure of the paragraph. The last paragraph also sums up the idea that Bird had a complex life but it didn’t minimize his greatness. All of these strategies bring the reader back to the purpose of the essay which proves that Charles Parker was a â€Å"most inventive melodist-a true songster.†

Persuasive Memo Research Paper Example | Topics and Well Written Essays - 1250 words - 2

Persuasive Memo - Research Paper Example Issue in the community of Seattle In a study conducted by Oxford Review of Economic Policy, evidence suggests that the implementation of ecological practice in business operation as a corporate social responsibility is more profitable to the company and contributes to their financial goals. In the same study, Reinhardt and Stavins debunked the traditional notion that going green is an altruistic sacrifice of profit just for the company to look good because evidence suggests that it can in fact be profitable (Reinhardt and Stavins, 2010). In addition, the study also showed that CSR in today’s business is a necessary management function as â€Å"firms that engage in unsustainable CSR may find themselves being pushed out of business† (178). If the ecological practice of businesses is such a big deal among customers, this is doubly important to the community of Seattle because survey showed that Seattle is among the most environmentally conscious in the whole of United Stat es (Rolph, 2010) and that they take the issue of climate change seriously considering that they had suffered from fiercer storms that claimed many lives and properties. Just recently, a windstorm hit Seattle which hurt people, and knocked out its power supply which affected thousands of its residents making environmental concern a pressing issue today (Fateh et al., 2013). Going green in supply chain as CSR To respond to the environmental issue that besets Starbucks, it must contribute its share in reducing its carbon footprint into the atmosphere that caused the climate change. Although the manifestation of the issue of climate change is local such as storms getting fiercer and more frequent in the community of Seattle that kills, hurt and destroy property, the solution is global. The solution is global because the collective carbon dioxide in the atmosphere that caused climate change is emitted by everybody of which Starbucks must contribute in reducing its carbon footprint even i f such business activity is somewhere else other than Seattle. The solution to the environment issue which besets the community of Seattle includes not only the reduction of carbon emission but also the avoidance of cutting trees that absorbs (and in effect minimizes carbon dioxide emission) carbon dioxide that reduce it to the planet’s regenerative capacity. Starbucks as a company is a direct agent of either aggravating the emission of carbon dioxide into the atmosphere or a socially responsible party that helps reduce carbon emission into the atmosphere. This is due to the fact that Starbucks raw material which is the coffee beans is a product of farming whose methods of growing can either aggravate the issue of carbon emission or help reduce it. There are coffee farming practices that aggravate the environment such as swidden farming or the cutting and burning of trees to plant crops of which Starbucks must avoid so as to retain the goodwill of the community of Seattle (Bu ttino, 2007). Starbucks must be particularly conscious in its CSR practice in the community of Seattle because it is the home of their headquarters. Any negative perception there will surely ripple to its other franchises across the world which could severely damage its brand and affect its bottom line negatively. Program specific: green supply chain Ethical sourcing of beans as a CSR practice will include not

Customer Service in the Blackshop Restaurant Case Study

Customer Service in the Blackshop Restaurant - Case Study Example Faced with the challenge of abandoning the manual system of managing reservations for the electronic one Alec Cerny had quite a tough decision to make. Â  The CHG was handling a good number of customers on a daily basis and in terms of operational efficiency, this required a very sophisticated system of managing reservations. The main problem to be tackled by the management at HCG was having a very efficient way of managing reservations in order not to lose customers while at the same time avoiding piling of pressure on available resources. The Backshop restaurant and affiliates were still using the manual way for making reservations where the customer could make phone calls and negotiate check on time and table choices with managers. One disadvantage of the manual system was that the information captured was inconsistent and was not easily transferable from day to day. Its transferability required extra labor and as such often was not done. another disadvantage arose especially when there were many customers calling in that anyone could step in and assist the managers; staff taking the reservations sometimes could bow to the press ure of customer when fixing check-in times causing bottlenecks to the bar& kitchen and limiting the restaurant's ability to turn the tables an extra time. Â  Procuring the reservations management software from OpenTable would assure consistency in customer information captured. Going electronic also meant keeping up to date with trends in business and customer service management as the future lies in technology. More people will do their things online in the future and as such it a worthy course. The system will assist the restaurant to save on time, cut costs, improve service, increase efficiency and ultimately attract repeat customers. The software also presents a unique opportunity to develop a good customer database, and allow sharing information between the restaurants.

Sensation and Perception Homework Essay Example | Topics and Well Written Essays - 1000 words

Sensation and Perception Homework - Essay Example For this process to complete the function of the eye is the most important one and its shape, size and location determine the capacity and functionality of the seeing capacity. Before deciding the design of eye for the new animal species, the most important thing we have to consider is the habitat and the surrounding environment where it will have to struggle for its survival. The foremost thing we should know is whether it is a hunting and assaulting animal or if it is a prey animal taken for food purpose. For the species involved in hunting the frontal eyes suit better because these eyes can give excellent depth perception due to the location in front of the head. On the other hand, the lateral position of eyes suits better for the prey-animals which gives them a panoramic view of the objects and helps them to anticipate and percept their hunters. After the placement of eye, its size and shape also determine its functionality. There are mainly two types of eyes, the most developed eyes like we, the human beings, have and the simple ones like a patch of photosensitive pigment which is found in many worms. The third option for designing the visual system is about its ability for movement. The movement of eyes helps the living beings to see objects from different angles giving better view of the object. However, the movement of the eyes is not sufficient in itself, the body shape should also facilitate in its movements to have wider seeing perspective. Thus, I would like for the new animal species a visual design which has frontal position to give excellent depth perception, medium sized to allow fast movements and the starling-like eye movements. 1.2 About fifty years ago, many a brain disorders were undiagnosed due to the lack of modern-day equipments and the research which by now has facilitated the medical professionals to anticipate and diagnose complicated neurological and brain disorders like Parkinson's, Anton's syndrome, and Meige syndrome etc. due to the lack of proper awareness about such disorders, the lives of patients were miserable and they had to rely much on their attendants. The real problem with some of the patients having brain disorder was that they did not realize they suffered some sort of disorder like in Meige syndrome in which the patients affirmed quite adamantly that they were capable of seeing even though they cortically blind. However, now the medical science has made extensive researches and is now able to control these disorders to some extent (Charles Bonnet Syndrome. 2007). However, it is a matter of concern that there is no specific treatment for these disorders and the medical professionals are able to control it in initial stages as well as handling some symptoms of the disorder. It is hoped that with further concentrated researches, these disorders will be controlled efficiently within next 50 years. 1.3 Structure of the Eye The structure of the eye or as is called the eyeball, is spherical approximately 2.5 cm in diameter. The outer part of the eye consists of three layers of tissue. The outside layer is the sclera having protective coating and it covers about five-sixth of the eye surface. The middle layer is called choroids, a vascular layer which is continuous with the ciliary body and with the iris. It lies at the front of the eye. The innermost layer of the eye is the

Unit 3 discussion domestic violence Research Paper

Unit 3 discussion domestic violence - Research Paper Example all that by producing a quality genetic generation with little or no traits of criminal behaviour but those focused on making our planet liveable in the next years to come. I believe the theory in as far as the notion of battery tendencies being experienced and not inherited. This is so because any form of violence including battery is acquired through the social learning process from abusive family members (Gosselin, 2009). Children learn from abusive parents and they pass these traits to their children through the same process of being violent and their children copying the same behaviour. An example to explain why the battery tendencies are not inherited is from observing siblings from the same parents acting out differently to resolve differences. Not all of them act violently and this explains why the behaviour is experienced. Children who experience or as exposed to more domestic violence and especially battery tend to be more violent that those who did not experience

The German Interior Minister Otto Schily announced that immigration Essay

The German Interior Minister Otto Schily announced that immigration rules would be relaxed to facilitate the entry of Indian sof - Essay Example Nevertheless, in the previous year German provided 10,000 green cards to technology professionals, among them being Indians. Though such an action would pose many security threats, German was ready to improve on their security so that no terrorist can pose as a soft ware expert to be issued with a visa. However, German portrays a good example of immigration and trade services globally, with host countries having to relax on some of the restrictive visa issues in order to gain a competitive advantage as other countries. However, one of the main issues that worry citizens in many of the hoist countries is likelihood of immigrants causing job shortage in the host country. Though India is a developing country, its successive growth in information technology and software is attributed to the fact that they outsource their services to multinational firms globally, but at a reliable cost. However, the United States remains the major country that receives a majority number of software expert ise from India. According to BBC news (2000), the United States had already proposed that it would increase the experts’ visas to 200,000, this shows that the rate of demand for the Indian software expertise is very high. Therefore, this third world country is has a comparative advantage in terms of software expertise. ... that has prevailed across the world, where countries mainly the developing countries have to contend with trade in services, as their skilled manpower is lured my developed countries, in the form of relaxed immigration rules and other incentives. Trade in services and immigration Trade and immigration are becoming connected since, for instance, trading in goods and services, and investing is expanding due to the low costs of globalization, transport, and availability of information. The result of this is an increased urge to study, work, and travel, or even to live abroad. When people move across borders and supply services in another country, this is regarded as trade. According to Pecoud (2007, p. 14), â€Å"trade and migration are interconnected in a globalized economy and that pressures towards liberalization may one day promote a narrow trade.† The increase of immigrants in developing countries has greatly increased with time. Immigration of skilled labor is encouraged by the developed countries and restrictive measures are minimized in order to enable these experts to venture into the country. Indeed, various benefits accrue to developed countries, with the major one being the use of immigrating human capital to advance their production capacity (Kuznar, n.d, p. 12). The immigration promotion of skilled labor is as a result of lack of a skilled workforce in these countries or the need to compete with other countries. If country A has more labor than country B, then it is only wise for country A to send labor to country B, via immigration, which is a direct method, or indirectly through exporting of goods. Thus, the movement of goods can substitute for the movement of people to various countries. In developed countries, prices of goods and services, as well as

The Values of Wal-Mart Research Paper Example | Topics and Well Written Essays - 500 words

The Values of Wal-Mart - Research Paper Example From this paper it is clear that its competitive advantages are not only its low-cost products, but including its high-value quality products, and sophisticated strategic management and control. These are what made Wal-Mart successful in the United States. After all, where do an individual can find products with substantially low prices, yet with high quality as well? The ultimate answer is at Wal-Mart itself.   Wal-Mart should replicate its original business model in China for the following reasons. China is a highly-dense and populated country. There is a great opportunity for Wal-Mart to serve more than 50,000 people in a certain location. Wal-Mart can eventually reach out to those people outside the center of a certain town or those not readily reach by advanced basic services. In this way, Wal-Mart could try to penetrate its services by reaching out customers who could not afford to go to the center of the town. Secondly, the low-cost strategy for its products is suitable in C hina where there are many competitors trying to be a cut above the other on the basis of price. Not only that, in China the labor cost is substantially low compared in the United States, so there is another great opportunity for Wal-Mart to replicate more than just what it had started into its other international counterpart. Finally, what it had already started in the international setting and applying into China is possible because the said country is home to various investors who could create what is essential for the business, exposing customers to a different level of understanding business.  In order for Wal-Mart to go forward is to improve its way of handling its human resource. Especially in its international expansion, what is essential is the thought that it could create a unified cultural approach within the entire organization.

Observation - Essay Example The students also watched â€Å"Story Box†. The â€Å"Story Box† showed a story of Korean traditional folktale using key expressions. The story repetitively mentioned, â€Å"What time is it?† When they finished watching the clip, the teacher again clicked the repeat button to have them practice the dialogues. First, they practiced as a whole, then with their partners. When they were done practicing, they volunteered a short scene from the â€Å"Story Box† without looking at the script on the screen. 4. Speaking Activity – What time is it Mr. Wolf? (15min.) – The teacher introduced the game to students with short video, and the students immediately grasped the idea because there was a similar game in Korean culture. However, the teacher told them there are many variations to this game, so students should listen carefully to her instruction. Like the traditional Mr.Wolf game in Korea, the teacher explained that there is one wolf who will be standing at the back of the room facing the wall while other students will be standing at the front of the room facing the wolf. When they start the game, other students need to shout their key expression which is â€Å"What time is it?† then, the wolf will randomly choose a time and tell â€Å"It’s ______ O’clock.† For example, when the wolf says, â€Å"It’s five O’clock† the students need to take five steps forward. When they got to wolf close enough, the wolf will shout, â€Å" It’s dinner time!† and try to catch one of them to be the wolf again. The students loved role-playing the dialogues. They were able to memorize the script perfectly after practicing speaking as a class couple times. Most students performed without having their scripts on their hands. The students were very competitive during the speaking activity. Some students were only interested in winning, so they ended up not reading the full sentences. These students were also stressed when the strips were given to students with lower English

School segregation Essay Example for Free

School segregation Essay As I walk through our schools and communit people living and socializing where they feel it is most affordable and comfortable. Individuals in society live to their own standards, producing their own living conditions. I was interested in writing about how the racial segregation came about in America at first. However, I noticed that the topic is too broad and after reading several articles regarding racial segregation in America, I noticed how interesting that this racial issue have caused an effect to the education system around the states. Schools around the United States are getting more and more heavily segregated by different races which could also cause an imbalance of income groups. For example, in New York City, we can see that the majority of the black people or minorities would prefer to live in areas such as Harlem or Brooklyn which relatively have a lower cost of living compared to Manhattan or downtown. Educational segregation was once widely viewed as a result of white racism. Roberts v. Boston was the first case to challenge segregation in public schools. In  this case, five-year-old Sarah Roberts was barred from her local primary school because she was black, and was forced to travel a great distance to get to school every morning. Her father sued the city of Boston to allow his daughter to attend a school in their neighborhood. The case was heard by the Massachusetts Supreme Judicial Court on Dec. 4, 1849. The following April, the court ruled that school segregation was constitutional. However, the fight to end public school segregation did not end there. This example shows that educational segregation had been  around for a long time and it is not getting any better. Besides that, it is known that public schools in one of the most racially diverse states in the country, New York are the most highly segregated, with minority and poor students increasingly isolated by race and class, according to a new report released by a civil rights policy group at the University of California, Los Angeles. The proportion of Latino and Asian students in the state of New York nearly doubled from 1989 to 2010, but their exposure to white students in public schools decreased during that time, the report said. And as minority student populations increased, the proportion of low-income students in those minority-majority public schools also rose, making the schools â€Å"severely segregated† in terms of both race and class, according to the report. This means that the children who most depend on the public schools for any chance in life are concentrated in schools struggling with all the dimensions of family and neighborhood poverty and isolation. Imagine how unfair the opportunities that these students could have gotten. Based on the Department of Education statistics looking at public  school enrollment in New York City within the past 20 years, it is found that while nearly 50 percent of public school students in New York state are considered low-income, black and Latino students tend to enroll at schools where about 70 percent of students are low-income, while white students attend schools where 30 percent of students are low-income. What’s more, the proportion of black students attending public schools considered â€Å"intensely segregated† which is define as having a student body that’s less than 10 percent white is on the rise. For example,  the country’s largest school system which is in New York City has 60 percent of the state’s black public school students attend school in the five boroughs, along with two-thirds of the state’s Asian and Latino students but only 10 percent of New York state’s white students. So, how did all this segregation came about? The changing demographics in the state paired with a lack of diversity-focused policies which include subpar transportation systems for students and restrictive admissions standards is one of the factor that caused the increasing segregation of public school students. Integration problems also started with parents choosing where to live. They are most definitely influenced by the perception that whites wont treat them equally, whether that perception is real or not, and whether its rooted in formal education or pop culture. Basically this residential segregation is defined as â€Å"the physical separation of cultural groups based on residence and housing,† which sorts different populations into their own sectors. The main â€Å"issue† of residential segregation is the wealthier white community not allowing blacks to move into their neighborhoods, which is  true in some atypical cases. However, it doesn’t make sense why anyone would want to live in a neighborhood where they feel threatened or unwelcome, pertaining to the minuscule amount of neighborhoods that still practice racism. Some real estate companies are assumed to sell certain properties to individuals based on race. Yet, this point is not valid. Buyers give real estate agents a budget for what they can afford and this is the factor that limits them to specific neighborhoods. Statistically, minorities’ average income is less than that of a white person. Most of  minorities such as Asian are still struggling to get a high paid job compared to the white people . Therefore, they can only afford certain size houses in particular neighborhoods. For example, in New York City, the Chinese people tend to live in Flushing and Chinatown where houses and the cost of living are relatively cheaper than other parts of the cities. In reality, people living where they can afford causes this so called residential segregation which then leads to our problem of discussion, the education segregation. I would like to research deeper on how racial inequality in America causes  education segregation in our society today and also why are people still stuck to this norm. I had read many interesting articles regarding education segregation which can further improve my knowledge on how economical imbalance can be connected to education segregation as well as residential segregation around the states. I will also get a better understanding on how education segregation causes inequality to the people and why is this issue still going on after so much efforts had been taken via the article â€Å"Still Separate, Still Unequal† by Jonathan Kozol. This racial segregation in education has to be solved efficiently really soon before it gets even worst. The United States of America is blessed with people from all over the world and is one of the richest country in terms of diversity and cultures. We should be grateful that America is able to bring together people of different races and therefore should try the best to promote equality among everyone and also prevent stereotyping. It is important that the government try to think of a more effective way for city planning, housing development, and even school district demographics to ensure that America’s education.

Short Duration Voltage Variations Engineering Essay

Short Duration Voltage Variations Engineering Essay For long time, the main concern of consumers in power system was the reliability of supply which means that the continuity of electricity. However, it is not only the reliability that consumers want these days, quality of electricity supply is also very important for consumers. The term, electric power quality, broadly refers to maintaining a nearly sinusoidal bus voltage at specified magnitude and frequency in an uninterrupted manner from the reliability point of view. For a well-designed generating plant, which generates voltages almost perfectly sinusoidal at rated magnitude and frequency, power quality problems start with transmission system and stay applicable until end users in distribution system. The power quality in power system are categorized as temporary phenomena and steady state phenomena The power qualities are characterized in the power system by different terms suggested by Padiyar, K.R.,(2007) under these two categorizes are summarized as follows: 1.2. TEMPORARY PHENOMENA Transients: Transients are short-duration, high-amplitude pulses superimposed on a normal voltage waveform. They can vary widely from twice the normal voltage to several thousand volts and last from less than a microsecond up to a few hundredths of a second. Transients can be classified as impulsive transients and oscillatory transients. Impulse transients are mainly caused by the impact of lightning strikes to the power system. The typical causes of oscillatory transients are capacitor or transformer energization and converter switching. While impulsive transient is a sudden and has non-power frequency change in voltage and current with a fast rise and decaying time, oscillatory transient has one or more sinusoidal components with frequencies in the range from power frequency (50Hz) to 500 kHz and decays in time. Short Duration Voltage Variations: Short Duration Voltage Variations are defined as the variations in the supply voltage for durations not exceeding one minute and caused by faults, energization of large loads that having large inrush currents or rapidly varying large reactive power demands of the loads. These are further classified as voltage sags, voltage swells and interruption. Long Duration Voltage Variations: Long Duration Voltage Variations are defined as the rms variations in the supply voltage at fundamental frequency for exceeding one minute, such as overvoltage, under voltage and sustained interruption. The causes of overvoltage (or under voltage) may be the switching off (or on) of a large load having poor power factor, or the energization of a large capacitor bank or reactors. Voltage Unbalance: Voltage Unbalance is the condition in which three phase voltages of the supply are not equal in magnitude and may not be equally displaced in time. The primary causes are the single phase loads, open circuit in any one phase of a balanced 3phase loads and unequal loads connected in each phase of a poly phase systems. Waveform Distortion: Waveform Distortion is defined as steady-state deviation in the voltage or current waveform from an ideal sine wave. These distortions are classified as dc-offset, harmonics and notching. The causes of dc offsets in power systems are geomagnetic disturbances, especially at higher altitudes and half-wave rectifications. These may increase the peak value of the flux in the transformer, pushing it into saturation and resulting in heating in the transformer. Power electronics equipments like UPS, adjustable speed drives injects harmonics in the power systems. Notching is a periodic voltage distortion due to the operation of power converters when current commutates from one phase to another. Voltage Fluctuations: Voltage Fluctuations are defined as the rapid, systematic and random variations in the supply voltage. This is also called as Voltage Flicker and is caused by rapid and large variations in current magnitude of loads having poor power factor such as arc furnaces. These large variations in load current causes severe dip in the supply voltage unless the supply bus is very stiff. Power Frequency Variations: Power Frequency Variations are the variations that are caused by rapid changes in the load connected to the system, such as the operation of draglines connected to a comparatively low inertia system. Since the frequency is directly related to rotational speeds of the generators, large variations in power frequency may reduce the life span of turbine blades on the shaft connected to the generator. Although these above terms are not new, customer awareness on power quality has increased. In recent times, power quality issues and custom solutions have generated tremendous amount of interest among power system authorities and engineers. International Electro technical Commission (IEC) and Institute of Electrical and Electronics Engineers (IEEE) have proposed various standards on power quality. This led to more stringent regulations and limits imposed by electricity authorities although they differ from one country to another in a limited extend. Although terms of power quality are valid for transmission and distribution systems, their approach to power quality has different concerns. An engineer of transmission system deals with the control of active and reactive power flow in order to maximize both the loading capability and stability limits of the transmission system. On the other hand, an engineer of distribution system deals with load compensation either by means of individua l or group compensation in order to maintain power quality for each load in the distribution system (Sankaran.C, 2002, John J.Paserba et al, 2000). The utilization of power electronic based power conditioning devices brought the solution for these power quality issues in distribution system. 1.2 FACTS CONTROLLERS In recent years, many multinational software companies and automobile industries established their units in India. In turn, it initiates many other small industries to supply their needs. The growth of these industries is found to be very fast and it pollutes the power system by injecting harmonics into it. These industries need electrical power for its operation. Establishing new power generation unit is not so easy in India due to the initial cost. In addition it has many constraints like fuel constraints, political constraints, economical constraints and technological constraints. This makes to think an alternate solution for the scarcity of power by improving the quality of existing power. Reducing the wastages and improving the quality of available power is equivalent to generation of power. To improve the reliability and deliver energy at the lowest possible cost with improved power quality, power supply industries require increased flexibility in the transmission and in the di stribution systems. The power industries are handling these challenges with the power electronics based technology of Flexible AC Transmission systems (FACTS). This term covers the whole family of power electronic controllers, some of which may have achieved maturity within the industries, while some others are yet in the design stage. As Higorani et al (1999) described the various VSC based FACTS controllers are available for power quality improvement. FACTs has been defined by the IEEE as follows. Power electronics based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and increase power transfer capability. In general, FACTs controllers can be classified as follows Series Controllers Shunt Controllers Combined series and shunt Controllers Combined shunt and series Controllers Based on the power electronic devices used in the controller, the FACTS controllers can be classified as: (A) Variable impedance type FACTS Controller (B) Voltage Source Converter (VSC) based FACTS Controller The variable impedance type controllers include: (i) Shunt connected- Static Var Compensator (SVC) (ii) Series Connected-Thyristors Controlled Series Capacitor or Compensator (TCSC) (iii) Combined shunt and series connected Thyristors Controlled Phase Shifting Transformer (TCPST) of Static PST The VSC based FACTS controllers are: (i) Static synchronous Compensator (STATCOM) (shunt connected) (ii) Static Synchronous Series Compensator (SSSC) (series connected) (iii) Interline Power Flow Controller (IPFC) (combined series-series) (iv) Unified Power Flow Controller (UPFC) (combined shunt-series) The VSC based FACTS controllers have several advantages over the variable impedance type. VSC based STATCOM response is much faster than a variable impedance type SVC. STATCOM requires less space than SVC for same rating. It can supply required reactive power even at low values of the bus voltage. In addition, a STATCOM can supply active power if it has an energy source or large energy storage at its DC terminals. It can also be designed to have in built, short-term overload capability. The only drawback with VSC based controllers is that it requires use of self-commutating power semiconductor switches such as Gate Turn-off (GTO) thyristors, Insulated Gate Bipolar Transistors (IGBT), Integrated Gate Commutated Thyristors (IGCT). However, the VSC based controllers build with emerging power semiconductor devices using silicon carbide technology will lead to the wide spread use of VSC based controllers in future. Among FACTs controllers, the shunt controllers have shown feasibility in terms of cost effectiveness in a wide range of problem solving from transmission to distribution levels. For more than a decade, it has been recognized that the transmittable power through transmission lines could be increased and the voltage profile along the transmission line could be controlled by an appropriate amount of compensated reactive power. Moreover, the shunt controller can improve transient stability and can damp power oscillation during a post-fault event. Using a high speed power converter, the shunt controller can further alleviate the flicker problem caused by electrical arc furnaces. .1 SERIES CONTROLLERS Static synchronous series compensator (SSSC) is series reactive power compensation devices used in transmission level. The series compensation is obtained by controlling the equivalent impedance of a transmission line, to regulate the power flow through the line. The SSSC can be considered as a static synchronous generator that acts as a series compensator whose output voltage is fully controllable, independent of line current and kept in quadrature with it, with the aim of increasing or decreasing the voltage drop across the line, thus controlling the power flow. The basic structure of a SSSC connected with the network is shown in Figure 1.1. Line C VSC TF Figure.1.1 Series Connected SSSC The SSSC injects a voltage Vq in quadrature with line current. It can provide either capacitive compensation if Vq leads the line current by à Ã¢â€š ¬/2 rad or inductive compensation if Vq lags line current by à Ã¢â€š ¬/2 rad. A relatively small active power exchange is required to compensate for coupling transformer and switching losses, and maintain the required DC voltage. 1.2.2 SHUNT CONTROLLERS STATCOM The schematic diagram of a STATCOM is shown in Figure.1.2. In principle, all shunt type controllers inject additional current into the system at the point of common coupling (PCC). VSC that uses charged capacitors as the input dc source and produces a 3à Ã¢â‚¬ ¢ ac voltage output in synchronism and in phase with the ac systems. The converter is connected in shunt to a bus by means of the impedance of a coupling transformer. A control on the output voltage of this converter is either lower or higher than the connecting bus voltage, controls the reactive power drawn from or supplied to the connected bus. The impedance of the shunt controller, which is connected to the line causes a variable current to flow and hence represents an injection of current into the line. As long as the injected current is in phase quadrature with the line voltage, the shunt controller can either supply or consume variable reactive power. Line C VSC TF Figure.1.2 Shunt Connected STATCOM A six pulse Voltage Source Converter (VSC) with suitable controller, the phase angle and the magnitude of the AC voltage injected by the VSC can be controlled. The Phase Lock Loop (PLL) ensures that the sinusoidal component of the injected voltage is synchronized (matching in frequency and required phase angle) with the AC bus voltage to which VSC is connected through a coupling inductor. Often, the leakage impedance of the interconnecting transformer serves as the coupling inductor. It also serves as harmonic filter for the voltage injected by the VSC. The injection of harmonic voltages can also be minimized by multi-pulse (12, 24 or 48), and/or multilevel convertors. At low power levels, the pulse width modulation (PWM) technique is sufficient to control the magnitude of the fundamental component of the injected voltage. The high voltage IGBT devices can be switched at high frequency (2 kHz and above) of sinusoidal modulation enables the use of simple LC-low pass filters to reduce harmonic components. 1.2.3 COMBINED SHUNT AND SERIES CONTROLLERS (a). Unified Power Flow Controller (UPFC): The Unified Power Flow Controller (UPFC) is the most versatile FACTS controller for the regulation of voltage and power flow in a transmission line. It consists of two-voltage source converters (VSC) in which one connected in shunt and the other one connected in series. The DC capacitors of the two converters are connected as shown in Figure.1.3. the shunt connected converters work as STATCOM and controls the reactive current injected in to the line. Series connected converter work as SSSC and control reactive voltage injected series with the line. The combination of these two converters enables to exchange active power flow between the two converters. The series connected converter can supply or absorb the active power. VSC Line VSC C STATCOM SSSC Figure 1.3 Schematic of UPFC The controllable power source on the DC side of the series connected converter, results in the control of both real and reactive power flow in the line at the receiving end of the line. The shunt-connected converter provides the required reactive power and injects the reactive current at the converter bus. Thus, a UPFC has 3 degrees of freedom whereas other FACTS controllers have only one degree of freedom or control variable. The concept of combining two or more converters can be extended to provide flexibility and additional degrees of freedom. A Generalized UPFC refers to the use of three or more converters out of which one shunt connected while the remaining converters are series connected (b). Interline Power Flow Controller (IPFC): An Interline Power Flow Controller (IPFC) refers to the configuration of two or more series connected voltage source converters sharing a common DC bus as shown in Figure 1.4. The Interline Power Flow Controller (IPFC) is used reactive (series) compensation of each individual line. In addition to this, the IPFC is capable of exchanging real power between the two or more compensated lines. To achieve this AC side of the series connected VSCs are connected in different lines and on the DC side, all the DC capacitors of individual converters are connected in parallel. This is possible because all the series converters are located inside the substation in close proximity. VSC1 Line-1 VSC2 C SSSC1 SSSC-2 Line-2 Figure 1.4 Schematic of IPFC for two transmission line using two VSC An IPFC is similar to a UPFC in that the magnitude and phase angle of the injected voltage in the line (main system) can be controlled by exchanging real power with the second line (support system) in which a series converter is connected. The basic difference with a UPFC is that the support system in the UPFC is the shunt converter instead of a series converter. The series converter associated with the main system of one IPFC is termed as the master converter while the series converter associated with the support system is termed as the slave converter. The master converter controls both active and reactive voltage within limits while the slave converter controls the DC voltage across the capacitor and the reactive voltage magnitude. 1.3 APPLICATION FACTS CONTROLLERS IN DISTRIBUTION SYSTEMS Although the concept of FACTS was developed originally for transmission network, later on this has been extended since last decade for improvement of Power Quality (PQ) in distribution systems operating at low or medium voltages. In the early days, the power quality referred primarily to the uninterrupted power supply at acceptable voltage and frequency. In the modern context, power quality problem is defined as any problem manifested in voltage, current or frequency deviations that result in failure or malfunctioning of customer equipment. However, the increase in the use of computers, microprocessors and power electronic systems has resulted in power quality issues involving transient disturbances in voltage magnitude, waveform and frequency. The nonlinear loads not only cause power quality (PQ) problems but also very sensitive to the voltage deviations. The unbalanced load in the distribution system like single-phase railway loading creates power quality problem at the distributio n level. The highly inductive load like arc furnace is a major source of creating power quality problems in distribution network. Hingorani et al (1999), was the first to propose FACTS controllers for improving power quality in distribution systems. They have called it as Custom Power Devices. These are based on VSC with appropriate controller. Based on the types of connection with the distribution network the custom power devices classifications are given below; 1. Series connected Dynamic Voltage Restorer (DVR) 2. Shunt connected Distribution STATCOM (DSTATCOM) 3. Combined shunt and series connected Unified Power Quality Conditioner (UPQC). The Dynamic Voltage Restorer (DVR) is a series connected custom power device in the distribution systems. The DVR is analogous to a SSSC in the transmission system. The main function of a DVR is to reduce voltage sags seen by sensitive loads such as semiconductor manufacturing plant or a paper mill. They have been designed to compensate three phase voltage sags up to 35% for duration of time less than half a second (depending on the requirement). If the voltage sag occurs only in one phase as in the case of Single Line to Ground (SLG) faults then the DVR may be designed to provide compensation for sags exceeding 50%. The capacitor is designed to store energy in the range of 0.2 to 0.4 MJ per MW of load served. A DVR is connected in series with the distribution feeder through a transformer. The low voltage winding of the transformer is connected to the converter. If a DVR is used mainly to regulate the voltage at the load bus, it injects a series voltage of the required magnitude if i t detects a voltage sag else remains in stand-by mode during which the converter is bypassed or it is not injecting voltage. It is necessary to protect the DVR against the fault currents as in the case of a SSSC. A DVR with IGBT/IGCT devices can be controlled to act as a series active filter to reduce the voltage harmonics on the source side. It is also possible to balance the voltage on the load side by injecting negative and/or zero sequence voltages in addition to harmonic voltages. The distribution STATCOM (DSTATCOM) is similar to a STATCOM in transmission system that it uses a VSC of the required rating. However, the VSC used in a DSTATCOM is a 6-pulse converter with SPWM or Space Vector Modulated PWM (SVPWM) control over the magnitude of the injected AC voltage while maintaining a constant DC voltage across the capacitor. In DSTATCOM, faster power semiconductor devices such as IGBT or IGCT are used instead of GTO as in STATCOM. The rapid switching capability provided by IGBT (or IGCT) switches enables the use of DSTATCOM for balancing, active filtering and flicker mitigation. The unbalanced system is balanced by injecting negative sequence current to the system. The active filtering is done by injecting harmonic currents in the system. A DSTATCOM can be viewed as a controlled variable current source. If more power that is reactive is required for compensation in distribution system, dynamic capacitor rating is increased. To increase the dynamic rating in the capacitive range, a fixed capacitor can be connected in parallel with DSTATCOM. By connecting energy storage device such as a Superconducting Magnetic Energy Storage (SMES) or a battery charged by a separate charging system on the DC side, it is possible to exchange real power with the network for momentary interruptions or large voltage sags for a limited time. The combination of shunt and series active filters which are connected on the common DC side as shown in Figure.1.5 used as Unified Power Quality Conditioner. This configuration is inspired by the UPFC in the transmission system. Akagi.H (1996), suggest the possibility of a centralized UPQC at the distribution substation that will provide harmonic isolation between the sub-transmission system and distribution system. The series branch of UPQC provides this harmonic isolation in addition to voltage regulation and imbalance compensation. The shunt branch provides for harmonic and negative sequence current compensation in addition to DC link voltage regulation. A UPQC can be considered as the combination of DSTATCOM and DVR. A DSTATCOM is utilized to eliminate the harmonics from the source currents and balance them in addition to providing reactive power compensation to improve power factor or regulate the load bus voltage (Padiyar.K.R. 2007). DVR DSTATCOM Load VSC1 Line VSC2 C Vs PCC I_AF VL +VAF Figure 1.5 Schematic of a Unified Power Quality Controller (UPQC) The terminology is yet to be standardized. The term `active filters or `power conditioners is also employed to describe the custom power devices. Irrespective of the name, the trend is to increasingly apply VSC based compensators for power quality improvement. LITERATURE REVIEW Development of gate turn off capability of semiconductor switches opened a way to second-generation FACTs controller using voltage source converter (VSC). This VSC can be operated at high switching frequency to provide a faster response. The STATCOM is a shunt connected power converter based compensating device. Van Zyl. A, et.al proposed an idea for Converter based solution to power quality problems on radial distribution lines (1996). This is a first power converter based shunt compensator. The concept of STATCOM was disclosed by Gyuayi,.L (1988). The concept gives the characteristics of VSC that are suitable for grid connected FACTS controller application. In the older version of reactive power compensation device, the reactive power is drawn from energy storage devices such as capacitor in the case of Static Var Compensator (SVC), but in STATCOM power is circulated within the connected network. The energy storage components used in the STATCOM is much smaller in capacity than tho se used in the SVC. In 1995, the first +100MVA STATCOM was installed at the Sullivan substation of Tennessee Valley Authority (TVA) in northeastern Tennessee. This device is mainly used to regulate 161kV bus during the daily load variation to reduce the operation of the tap changer of a 1.2GVA 161kV/500kV transformer. The VSC used in this STATCOM is made up of eight two level VSC resulting a 48 pulse VSC. The output of each VSC is integrated by a complex interface zigzag connected interfacing transformers, because this is a two-level VSC, a series connection of five of gate-turn-off (GTO) thyristor is used as a main switch. The staircase type switching scheme at fundamental frequency (60Hz) was used as a control scheme for this STATCOM. Due to slow switching speed of the GTOs; the firing angles of the output wave form are fixed. Therefore, the amplitude of each output waveform is controlled by exchanging real power of the DC-link capacitor with the power grid. The power quality problem at distribution level like voltage regulation, harmonics reduction, power factor correction, reactive power compensation and unbalance compensations need to be carried out at distribution level. The DSTATCOM, connected to the grid through the coupling inductor at the point of common coupling (PCC) is controlled in such a way that it exchanges only reactive power with the grid. This is achieved by injecting current in quadrature with the grid voltage. The DSTATCOM is developed from the STATCOM used in transmission system for voltage regulation. Hingorani, N.G,. et al (1999) explored the concept and technology of Flexible AC Transmission Systems. The detailed modeling and average modeling of DSTATCOM and its performance for voltage regulation application is studied by Pierre Giroux et al (2000). This gives the concept of PWM controlled DSTATCOM in dq coordinate system. Sen Sarma. P.S., et al (2001) Analyzed and evaluated the performance of a distribution STATCOM for compensating voltage Fluctuations. Sao, C.K et al (2002) proposed the application of DSTATCOM from voltage regulation to reactive power compensation, power factor correction, mitigation of voltage sag and swell in distribution system and created a benchmark system to test all these performance. This DSTATCOM is controlled by PI controller in dq coordinate using parks transformation matrix. This work reduced the computation time of the controller by avoiding Inverse Parks transformation. The application of DSTATCOM is extended to compensate the reactive power for isolated induction generator by Bhim Singh et al (2003). This gave the mathematical modeling of induction generator and DSTATCOM. As the DSTATCOM is suitable for distribution system and stand alone system researcher focused to increase the performance of the controller. The concept of using DSTATCOM as a shunt active filter to reduce the current harmonics in the industrial application and gradually extended to power systems application by Georges, S. et al (2006) and Kannan, H.Y. et al (2008). The concept of Generalized Instantaneous Reactive Power Theory for Three-phase Power Systems is exploited by Akagi, P., et al (1984) and Fang Z heng Peng et al (1996). The concept of instantaneous reactive and real power is brought by them in to the design of controller for closed loop operation of VSC. A Survey of Current Control Techniques for Three-Phase Voltage-Source PWM Converters is brought by Marian P., et al (1998). These current control techniques provided a path way for direct control of VSC output current. Design and Implementation of DSTATCOM for fast load compensation of unbalanced loads was implemented by Wei-Neng Chang et al (2009). The controller for unbalanced system was built by phase sequence method and pulses are generated by current regulated PWM method. The Space Vector Modulation (SVM) PWM technique was an emerging control technique used in Voltage Source Converter (VSC) for controlling its output voltage by Atif Iqbal et al (2010). A New Vector-Based Hysteresis Current Control Scheme for Three-Phase PWM Voltage-Source Inverters was developed by Mansour Mohseni et al (2010). This thesis tries to appl y Vector-Based Hysteresis Current Control Scheme for DSTATCOM for power factor improvement. This research is focusing to use the SVM based PWM technique for DSTATCOM operation in addition to PI controlled SPWM in dq coordinate systems. This also extends the application SVM based HCC from inverter to DSTATCOM. 1.5 PROBLEM STATEMENT The voltage at distribution systems need to be maintained at 1pu at all conditions. The reactive power control plays an important role in maintaining the bus voltage at 1pu in the distribution bus.Classical reactive power controllers like fixed capacitors, switched capacitors, TCR, SVC etc have slow response and bulky. A DSTATCOM, though a costlier device it has faster response. Hence it is preferred when faster correction of voltages is required. It is required to design specific controllers for voltage regulation, power factor correction and unbalanced system compensations. All the above problems can be solved by installing a DSTATCOM with proper controllers. 1.6 OBJECTIVES The main aim of this thesis is to design and implement the controller for DSTATCOM to improve the power quality namely voltage regulation, voltage sag or swell, reactive power compensation, power factor improvement and unbalance compensation. The controllers presented in this work will aid the design engineers to develop an integrated controller with multiple control objectives. The main objectives of this thesis include To study the concepts of DSTATCOM and bring out the design procedure of it. To understand the controller principle for various applications and explore it for novel controller design. To design the new control algorithm namely PI controlled Space Vector Pulse Width modulation method and Study the performance of DSTATCOM for this controller to improve the power quality issues such as voltage regulation, power factor improvement and reactive power compensation. To compare this SVPWM controller performance with the performance of existing Sine Pulse Width Modulation (SPWM) method. To modify the basic SVPWM method so as to extend its controller to directly control the flow of current of DSTATCOM. This method of controller is called SVPWM based Hysteris Current Controller (HCC) method. To suggest a new control techniques for unbalanced system compensations using sequence analyzing method and validate its performance for power quality improve improvement. To explore the design of DSTATCOM components. To identify the controller for compensating balanced and unbalanced systems. 1.7 THESIS ORGANISATION This thesis contains seven chapters summarized as follows: In Chapter 1 need for improving the quality of power is discussed the power quality issues and various Flexible AC Transmission System (FACTS) controllers available for the power quality improvements in the transmission systems and distribution systems. This chapter also includes the review of the literature, outlines the research objectives and the organization of the thesis. Chapter 2 describes the general method for designing a DSTATCOM for power quality improvement. The DSTATCOM consists of a DC capacitor, a VSC, a coupling inductor and the controller. This chapter gives a method of designing the coupling inductor, the DC capacitor and selecting the power electronic switches for the VSC. It also focuses on analyzing the controllers of DSTATCOM for power quality improvements. In Chapter 3, the mathematical modeling of a two-level VSC based DSTATCOM is described. This Chapter also presents the PI controlled Sine Pulse Width Modulation (SPWM) and Space Vector PWM (SVPWM) switching techniques for voltage regulation applications. The comparative performance of these switching techniques is carried out. The control logic is developed from the power invariant property of the Parks transformation of

Evidence-Based Practice on Wound Packing

Evidence-Based Practice on Wound Packing Evidence-Based Practice on Wound Packing Following Incision and Drainage Arlena Davis The first article was related to MD’s not using any packing when it comes to treating I D’s. Many times packing is used to debride the wound and keep fluids from pooling under the skin as well as keep area free of infection. In order to understand the outcome we need to fully understand what is involved.An abscess is a collection of pus, surrounded by inflamed tissue and usually localized (Pfenninger Fowler, 2010).The reason we need the packing is related to having an abscess and we need to keep the area clean. Leinwand 2013states packing is thought to aid hemostasis, and prevent reorganization of the abscess, we sought to determine whether packing could be omitted with equal efficacy. The second article I chose was Alimov, V., Lovecchio, F., Sinha, M., Foster, K. N., Drachman, D. (2013)to the use ofa silver-containing hydrofiber dressing for filling abscess cavity following incision and drainage in the emergency department. Is using packing always effective? Can we have equal efficacy when there is no packing used? These are questions that were sought after and answered in this particular article. At the end of the trial the patients reported faster heling and les pain as it relates to traditional packing. In the research that was conducted in the first article entitled  Use of Silver-containing hydro fiber dressing in filling the cavity related after incision and drainage at the emergency department: a randomized controlled trial. Advances in skin wound care, (Alimov, Lovecchio, Sinha, Foster, Drachman, 2013), clinical study design was used. This study design took the form of prospective randomized control trial. The sample size in this case was ninety-two patients (Alimov, Lovecchio, Sinha, Foster, Drachman, 2013). These patients were more than 18 years of age and were suffering from cutaneous abscess. The ninety-two study participants had been randomly assigned into two groups. These are the intervention group (Skillman, Aquacel, New Jersey, and Convatec) and the iodoform group (Alimov, Lovecchio, Sinha, Foster, Drachman, 2013). The iodoform group is the control group in this case. Of these two groups, it was noted that there were no differences in terms of demography as well as their clinical characteristics. The weaknesses that are evident in data collection are that the researchers should have randomly selected the patients in two equal groups that is 46 persons per each group. The follow-up period is also not consistent. Inconsistency comes in whereby the study claims that patients were followed up in a span of the first two weeks (Alimov, Lovecchio, Sinha, Foster, Drachman, 2013), though the follow-up was not continuous. However, the strength of this study is that it had both the intervention group and the control group. The intervention group comprised of four subgroups depending on the intended intervention. These four groups were based on interventions such as Convatec, New Jersey, Aquacel, and Skillman) (Alimov, Lovecchio, Sinha, Foster, Drachman, 2013).The other strength of the study is that it was able to provide a comparison on the level of pain between the patients initial visit and the first follow-up. In relation to the second article that dealt with the incision and the drainage of the subcutaneous abscess without packing, (Leinwand, Downing, Slater, Beck, Burton, Moyer, 2013) clinical study design was also used. In this regard, the clinical study took the form of retrogressive randomized control trial. The sample size in this study was a hundred patients, who were reported to be suffering from subcutaneous abscesses back in between May 2008 and December 2010. These 100 patients were assigned into two groups namely, the packing and the non-packing groups (Leinwand, Downing, Slater, Beck, Burton, Moyer, 2013). In this case, there were some exceptions in that some patients portraying some given conditions could not be considered. Such conditions include; patients who are immunosuppressed, or rather those suffering from diabetes. The other exception was in case the patient had a perineal or a pilonidal abscess. Last but not least, the other exception was on whether the abscess is secondary to the previous operation. These exceptions can be used as a basis for comparison among the sample, to the patients who will be seeking treatment. There are several weaknesses of the study in terms of data collection, with one of them being that it was not age specific. Apart from that, the other weakness is that; the patients were only clinically evaluated, in case there was suspicion of recurrence in the follow-up calls on the day seven and thirty (Leinwand, Downing, Slater, Beck, Burton, Moyer, 2013). These two days were referred to as postoperative. The other weakness is that, of the 100 patients, only 85 patients managed to complete the study. The study does not indicate the whereabouts of the 15 patients. On the other hand, the strength of this study is that it omitted other patients who had some other conditions that could interfere with the results. Such exceptional cases were the diabetic, immunosuppressed (Leinwand, Downing, Slater, Beck, Burton, Moyer, 2013), among others. Identification, critical appraisal, and synthesis of evidence from research articles is an essential skill in evidence-based practice (EBP) (Titler, 2008). This paper will critique two primary research articles related to the issue of wound packing following incision and drainage. The first article is authored by Leinwand et al. (2013) and is entitled â€Å"Incision and drainage of subcutaneous abscesses without the use of packing†. The second article is authored by Alimov et al. (2013) and is entitled â€Å"Use of a silver-containing hydrofiber dressing for filling abscess cavity following incision and drainage in the emergency department: A randomized controlled trial†. The study by Leinwand et al. (2013) sought to determine whether omission of the wound packing component in the management of subcutaneous abscess has similar efficacy to wound packing. The study employed a prospective randomized controlled trial design whereby 100 participants were randomized to either the wound packing group or to the non-packing group. The study enrolled pediatric participants aged less than 18 years with subcutaneous abscesses. The sample size for the study was small (100). Consequently, the study did not have significant statistical power as a sample size of 4000 was required to gain power of 80%. The researchers, however, accepted the small sample size as it was practical for the purposes of the study. The selected sample is appropriate to the population of interest because the participants were experiencing the phenomenon of interest that is abscesses requiring incision and drainage. Regarding data collection, similar pre-intervention data was collected on the operative day for all participants. These data included age, gender, and location and size of the abscess. Post-intervention data was collected through follow-up telephone calls by a pediatric surgery nurse specialist. These calls were made on the 7th and 30th post-operative days and included information on general wound appearance, adherence with warm soaks and antibiotic therapy, presence of fever, and timing of pack removal. The reliance on self-reported information may have introduced information bias due socially desirable responding and problems with recall (Fadnes, Taube, Tylleskar, 2008). Of the 100 participants who enrolled for the study, only 85 completed the study. The study found that the packing group and non-packing groups did not vary statistically with respect to abscess recurrence rates, initial parameters, and incidence of methicillin-resistant staphylococcus aureus (MRSA). Only two abscess recurrences were reported, one for each group. In their discussion, the authors contextualize these findings in light of pre-existing evidence. They note that the findings of their study are identical to those of similar previous studies on both adults and children. The authors also compare the strengths and weaknesses and merits and demerits of their study and intervention with those of previous studies. They also discuss the two cases of treatment failure. Lastly, they provide recommendations for future studies. On the incorporation of evidence into treatment protocols, integration of research findings into treatment protocols/procedures occurs through the process of evidence-based practice. Research articles relevant to a clinical issue of concern are identified, appraised critically, and their findings used to make specific recommendations for practice on incision and drainage (Dontje, 2007). The Purpose of the Alimov et al. (2013) study was to investigate whether packing of abscess cavity with a silver-containing hydrofiber dressing instead of the standard iodoform dressing leads to less pain and faster wound healing. The study employed a prospective randomized controlled trial design whereby participants were randomized to the silver-containing hydrofiber or standard care groups. The study population consisted of adults aged more than 18 years who visited the emergency department of a teaching hospital with cutaneous abscesses >2cm in diameter that required incision and drainage. The selected sample consisted of 92 patients. The sample for the study is appropriate to the selected topic as it focuses on the issue of incision and drainage protocols. Data for the study was collected and documented on a standard form except for pain. The data collected included pertinent demographic and clinical variables. Pain was assessed using a self-report scale, the Wong-Baker FACES Pain Rating Scale. The use of a self-report scale for pain may have introduced social desirability bias. The findings of the study may have also been contaminated by bias due to the manual measurement of the dimensions of the abscess cavities. The primary outcome measures for the study were the proportion of patients with a reduction of 30% or > in the surface area of the abscess at the first follow up visit (between 48 and 72 hours). The other main outcome variable was proportion of patients with 30% or > decrease in the surrounding cellulites at the first visit. The secondary outcome measure was the change in self-reported pain intensity at primary and consequent visits. The study found that 82.6% of the patients in the silver-containing hydrofiber group had a reduction of 30% or > in the surface area of the abscess compared to the 26.1% of the subjects in the iodoform group (p In this article, the number of participating pediatric patients who had subcutaneous abscesses was one hundred. Patients who successfully completed the study were only 85: 43 packing group and 42 non-packing group. There existed an arithmetic variance between the two groups that concerned the initial parameters, recurring abscesses, (single in every group), or incidence of MRSA (81.4 packing groups over 85.7 non-packing group). Subcutaneous abscesses incision, as well as drainage without the utilization of packing, is an effective as well as a safe technique. This article should present the data in a more transparent way. In this article, there was a prospective enrollment of 92 patients and these patients. There was also random assignment of these patients to the iodoform groups or Aquacel Ag. The SD was 12.0, and the average age was 38. The patients in iodoform group were 43 while those in Aquacel group were 49. There two groups lacked disparity in clinical and demographic characteristics. The domino effect of the deterioration study pointed out that the Aquacel Ag was autonomously associated with over 30% abscesses’ surface area reduction. This, however excluded first follow-up cellulitis. The pain intensity also decreased significantly as perceived by the Aquacel group patients. In cutaneous abscesses patients, there was faster wood healing as well as pain reduction while using antimicrobial-hydro fiber ribbon form of dressing than while using iodoform dressing. This article is important as it offers information on which choice is best while dressing. It is recommended thatmore research on this subject as this will provide more information on subcutaneous abscesses treatment. These articles will help me in my career as a nurse practitioner because of the versatility of the procedures and the information provided. In summary, this paper has critiqued two research articles related to the issue of wound packing following incision and drainage. The articles by Leinwand et al. (2013) and Alimov et al. (2013) have been critiqued in terms of their purpose, design, sample, data collection procedures, results, and discussion. References Alimov, V., Lovecchio, F., Sinha, M., Foster, K. N., Drachman, D.

Warrior Marks :: essays research papers

Alice Walker, Warrior Marks: Female Genital Mutilation and the Sexual Blinding of Women. New York: Harcourt Brace, 1993, 373pp. Female genital mutilation, also known as female circumcision, is a practice that involves the removal of part or all of the female external genitalia. It occurs throughout the world, but most commonly in Africa where they say that it is a tradition and social custom to keep a young girl pure and a married woman faithful. But to some Westerners, the practice is viewed as being primitive and barbaric. We react with disgust and find it nearly incomprehensible that female genital mutilation can occur in the world today   Ã‚  Ã‚  Ã‚  Ã‚  In Warrior Marks, Alice Walker looks at the reality that millions of African, Asian and Indian women suffer from genital mutilation. The book begins with the re-telling of a story of how she lost one eye. This wound was inflicted on her when she was three years old and for years, she felt handicapped and isolated. Her brother, who caused this accident with a BBgun, is referred to as a â€Å"warrior† and the blinding of her eye is the warrior mark. Her visual mutilation is what helped her see the subject of genital mutilation. She sees it as a terrible form of patriarchal oppression, characterized by â€Å"the feeling of being overpowered and dominated by those you are bound to respect.† The book goes on and discusses the health risks that are involved in the practice. It talks about how the women who perform the surgery have a minimal knowledge of anatomy and hygiene, which results in infections of the genital and often results in the transmission of the HIV virus. Besides the initial pain of the operation, these girls also suffer long-term physiological, sexual and psychological effects. A mother reveals that she would stop the pain and betrayal if she could but because of tradition, she and others would risk banishment, torture and abuse.   Ã‚  Ã‚  Ã‚  Ã‚  In the end, Walker emphasizes that these African women are not victims, but survivors. In the book, the women grow gardens on dry land and trade food, clothing and crafts in the marketplace. Whether a battered wife, a rape survivor or genitally mutilated woman, Walker concludes that a woman warrior learns that if she is injured, she can fight back. She closes by saying, â€Å"Your wound could be your guide.†   Ã‚  Ã‚  Ã‚  Ã‚  Female circumcision is based on gender oppression and degradation of women.

Another Heart of Darkness Essay -- essays research papers

Ignorance and Racism Joseph Conrad develops themes of personal power, individual responsibility, and social justice in his book Heart of Darkness. His book has all the trappings of the conventional adventure tale - mystery, exotic setting, escape, suspense, unexpected attack. Chinua Achebe concluded, "Conrad, on the other hand, is undoubtedly one of the great stylists of modern fiction and a good story-teller into the bargain" (Achebe 252). Yet, despite Conrad's great story telling, he has also been viewed as a racist by some of his critics. Achebe, Singh, and Sarvan, although their criticisim differ, are a few to name. Normal readers usually are good at detecting racism in a book. Achebe acknowledges Conrad camouflaged racism remarks, saying, "But Conrad chose his subject well - one which was guaranteed not to put him in conflict with psychological pre- disposition..." (Achebe, 253). Having gone back and rereading Heart of Darkness, but this time reading between the lines, I have discovered some racism Conrad felt toward the natives that I had not discovered the first time I read the book. Racism is portrayed in Conrad's book, but one must acknowledge that back in the eighteen hundreds society conformed to it. Conrad probably would have been criticized as being soft hearted rather than a racist back in his time. Conrad constantly referred to the natives, in his book, as black savages, niggers, brutes, and "them", displaying ignorance toward the African history and racism towards the African people. Conrad wrote, "Black figures strolled out listlessly... the beaten nigger groaned somewhere" (Conrad 28). "They passed me with six inches, without a glance, with the complete, deathlike indifference of unhappy savages" (Conrad 19). Achebe, also, detected Conrad's frequent use of unorthodox name calling, "Certainly Conrad had a problem with niggers. His in ordinate love of that word itself should be of interest to psychoanalysts" (Achebe 258). Conrad uses Marlow, the main character in the book, as a narrator so he himself can enter the story and tell it through his own philosophical mind. Conrad used "double speak" throughout his book. Upon arriving at the first station, Marlow commented what he observed. "They were dying slowly - it was very clear. They were not enemies, they were not cri... ... (Singh 278). Conrad didn't write his book to the extreme of racism. Overall, the natives appeared better humans than the Europeans in Heart of Darkness. Conrad's ignorance led to his conformity to racism. His ignorance of not completely "granting the natives human status" leads him to social categorization. C. P. Sarvan wrote in his criticism, quoting Achebe, "Racism and the Heart of Darkness," "Conrad sets up Africa 'as a foil to Europe, a place of negations... in comparison with which Europe's own state of spiritual grace will be manifest.' Africa is 'the other world,'..." (281). Achebe, Chinua [An Image of Africa: Racism in Conrad's Heart of Darkness.] Heart of Darkness. By Joseph Conrad 3rd ed. Ed. Robert Kimbrough.
