Operations Mangement Coursework (Five Questions)

Operations Mangement (Five Questions) - Coursework Example An organization uses operating performance to attract and retain customers and also serve them in a profitable manner (Hsu, Tan, Kannan &Keong Leong 2009, p. 835). Operations vary in different industries, but in general, they include things like on-time delivery, customer acquisition, running efficiently, and developing new products and services. According to Barney (1991, p. 56), the internal organization of resources in a firm is the determinant of the firm’s performance and strategy. Barney further defines resources as capabilities, assets, attributes, knowledge and information, and all things that are under control of the firm to enable it implement strategies that aid in improving effectiveness and efficiency. Porter (1996), on the other hand, asserts that the most essential resources are the ones that are hard to imitate, superior in use, more valuable, and difficult to substitute. According to the two authors, a firm’s competitive advantage resides on inherent heterogeneity of strategic resources that are controlled by the firm (Barney 1991, Porter, 1996). Therefore, failure to strategically integrate operations, finance, and marketing results in a weak and inconsistent company’s strategy, and its execution will be inefficient and flawed. In today’s world operation activities have become the dominant element in planning and management of production capacity (Stevens 2009, p. 5). Whether you are running a manufacturing firm or a service company, the organization deals with issues of what and the amount of production, and means of measuring performance. In many firms, operations are viewed as an identical partner with finance and marketing. The operations staff of an organization concerns with the planning and management of production capacity, accompanied by production facilities and equipment. Operations gives an

Similarities and Differences in Tourist Attractions in Northerrn and Essay

Similarities and Differences in Tourist Attractions in Northerrn and Southern California - Essay Example Northern and Southern California are the leading travel destination in California. Both regions have tourist attractions, which attract tourists throughout the year (94). However, Northern California has more destinations as compared to Southern California in terms of parks and Gold mining. Therefore, although California is a  prime  tourist destination in the United States, Northern California contributes more to the tourism industry as compared to the Southern California. This paper compares and contrasts Northern and Southern California in terms of their similarities and differences in entertainment, tourist attractions, and lifestyles. In Northern California, in El Dorado County, Coloma, Marshall Gold Discovery State Historic Park is an  outstanding  tourist attraction. The park is situated 18 miles in the south of Auburn, or on Highway 49, 9 miles on the Northern part of Placerville (95). The park has tree-lined streets, which are  quiet  all year long. A significant number of visitors visit the park in summer or for any special events in the year. One of the  memorable  events that attract visitors is the  yearly  commemoration of the gold discovery of 1848 in every January (96-7). The park attractions sites include buildings that have continued to exist from the gold rush, trails, picnic areas, and a replica of Sutter's Mill. In addition, the Gold Discovery Museum signifies gold-rush-era exhibits that include mining tools and other memorabilia (98). The park  is opened  daily while the buildings and museum  are opened  daily except on Christmas, New Year day, and Thanksgiving Day. Gold Bug Park is another tourist attraction in Northern California. The park  is situated  in Placerville; 1 mile north of Highway 50 on Bedford Avenue (99). The park’s outstanding characteristic is the Gold Bug Mine, which is a  tiny, hard rock gold mine. The Gold Bug Mine contains two lighted streams, which are accessible to the  com munity  for self-guided trips. The streams are 147 feet and 362 feet correspondingly (100). In Addition, there are gift shop hill-walking trails, historical museum of the public area,  stamp  mill and picnic sites. The Empire Mine State Historic Park found in the Northern California, Nevada County, is also a tourist attraction. Grass valley is where the park  is situated. In California, the Empire Mine  is recognized  as the biggest, highest and the deepest operating hard rock mine. The mine produces about 6 million ounces of bullion (102). Mine’s buildings, restored gardens and the vendors’  residence  surround the park. In addition, it has trails of 10 miles. The park offers travels of the owner’s  home  and the  mine’s  home. In addition, Malakoff Diggins State Historic Park attracts a significant number of tourists in Northern California. The park  is located  26 miles northeast of Nevada City on North Bloomfield Road (103) . The park has  enormous  cliffs as a result of  mighty  streams water that washes the entire mountains for miners to find gold. In addition, the park has a 7,847-foot  bedrock  passageway that  acts  as a drain. The  tourist  centre comprises displays on life in the old mining town of North Bloomfield (104-5). South Yuba River State Park is also a tourist attraction in northern California. The park  is situated  5 miles in the Northern city of Nevada. It extends along more than twenty miles of the South Yuba River

Coca Cola Company Operations And Strategies Business Essay

Coca Cola Company Operations And Strategies Business Essay Coca Cola was invented by Doctor John Pemberton a pharmacist from Atlanta, Georgia in May, 1886. John Pemberton invented the Coca Cola formula in a three legged brass kettle in his backyard. The name was a suggestion given by John Pembertons bookkeeper Frank Robinson. The soft drink was first sold to the public at the soda fountain in Jacobs Pharmacy in Atlanta on May 8, 1886. About nine servings of the soft drink were sold each day. Sales for that first year added up to a total of about $50. But it cost John Pemberton over $70 in expanses, so the first year of sales were a loss. Until 1905, the soft drink, marketed as a tonic, contained extracts of cocaine as well as the caffeine-rich kola nut. In 1887, another Atlanta pharmacist and businessman, Asa Candler bought the formula for Coca Cola from inventor John Pemberton for $2,300. By the late 1890s, Coca Cola was one of Americas most popular fountain drinks, largely due to Candlers aggressive marketing of the product. With Asa Candl er, now at the helm, the Coca Cola Company increased syrup sales by over 40% between 1890 and 1900. On April 23, 1985, the trade secret New Coke formula was released. Today, products of the Company are consumed at the rate of more than one billion drinks per day. Now company produces more than 300 beverage brands. The corporate headquarters are in Atlanta, with local operations in over 200 countries around the world. More than 70 percent of the income comes from outside the U.S, but the real reason they are a truly global company is that the products meet the varied taste preferences of consumers everywhere. But the Company has several issues that influence its profits and position in the market. Such as still producing its Coca Cola Classic product, which contains high levels of sugar and caffeine which is negatively impact costumers health.   And it may reduce the demand for some of their products and impact customers trust or loyalty.    The second one is banned sales of Coke in its cafeteria by the Indian parliament. When coca cola was tested, it was found that it includes high concentrations of pesticides and insecticides, including lindane, DDT, malathion and chlorpyrifos. Some samples tested showed the presence of these toxins to be more than 30 times the standard allowed by the European Union. But the same drinks were found to be safe in US. The third issue is boycott against the companys using huge amount of water from the common groundwater source. And as a result of its operations the scarce water has been polluted by Coca Cola (case study Coca Colas strategy, www.thecoca-colacompany.com). Mission and Vision Statement Mission Statement Coca Cola Companys mission statement is to maximize shareowner value over time. In order to achieve this mission, they are creating value for their consumers, bottlers, and their communities. The Coca Cola Company creates value by executing comprehensive business strategies (mission vision values, (2009) www.thecoca-colacompany.com). Vision Statement To achieve sustainable growth, Coca cola has established a vision with clear goals: Profit: Maximizing return to shareholders; People: Creating great place to work where people are inspired to be the best they can be. Thomson, Gamble, and Strickland (2006) suggest that Coca Cola believes a reputation for workforce diversity makes recruiting employees easier (talented employees from diverse backgrounds often seek out such company); Portfolio: Bringing to the world a portfolio of beverage brands that anticipate and satisfy peoples desires and needs; Partners: Nurturing a winning network of partners and building mutual loyalty; Planet: Being a responsible global citizen that makes a difference (mission vision values, (2009) www.thecoca-colacompany.com). Companys Strategies Brand development Strategy. P.Kotler and K.L.Keller (2009) suggest that brands signal a certain level of quality so that satisfied buyers can easily choose the product again. So Coca Cola Company to far reach and to manage remaining in the limelight it created Brand development strategy. This strategy is effective as it has been able to construct, manage as well as maintain its brand image since yesteryears. As Kotler et. al., (2009) argue, brand loyalty provides predictability and security of demand for the company and creates barriers to entry that make it for other firms to enter the market. The brand loyalty is the instrumental in keeping up companys brand image. Over the years, Coca Cola has passed several tests of brand enhancement and the company makes it a point that the products under the banner Coca Cola continue to invade the minds of the consumers. It involves 4000 customers to test 20 brand attributes every month. With regard to the brand development of Coca Cola Zero, the company came out with an advertisement, which was quite different from the conventional ones. In this regard, (no calorie beverage), it has shelled out three types of products: Coca Cola Classic; Diet Coke; Coca Cola Zero. There are few experts who believe that when Coca Cola had the tag line of The Real Thing, it was really that but with the invention of various categories of coke, the real thing changes to many things, and the original flavor is usually lost. Hence, the brand building strategies should be such that it does not confuse people and is able to retain consumers despite the fact that several new non alcoholic beverage firms are on the (development strategy of Coca Cola, finance.mapsofworld.com). Business Intelligence Strategy. In order to know what consumers prefer it intends to use Information technology (IT) to monitor the pulse of its customers.  Ã‚   According to Information Week article titled Cokes RFID-Based Dispensers Redefine Business Intelligence, Coke plans to roll out the Freestyle drink dispenser nationwide which is taking the concept of customer choice to new heights, and the most interesting aspect is the technology its built on. According to Rainer and Turban (2009), business intelligence (BI) is applications and technologies for consolidating, analyzing and providing access to vast amounts of data to help users make better business and strategic decisions. Freestyle will become Cokes front-line robotic army for BI, sending massive amounts of consumption data back to the beverage companys Atlanta headquarters. The dispensers collect data on what customers are drinking and how much, and transmit that information each night over a private Verizon wireless net work to Cokes SAP data warehouse system in Atlanta. Unique byproduct of this BI enabled dispenser is that Coke can try out new flavors and get back almost real time feedback on the viability of its success.     With a competitive advantage like this, I think its a good idea Coke store its IT details to develop its recipe formula. Price strategy. Sometimes Coca Cola Company changes their product prices according to the season. Summer is supposed to be a good season for beverage industry in Pakistan. So in winter they reduce their prices to maintain their sales and profit. But normally they reduce the prices of their pet bottles or 1 litter glass bottle. Promotion strategy. They get or purchase shelves in big departmental stores and display their products in those shelves in that style which show their product clearer and more attractive for the consumers (Coca colas business intelligence strategy, www.itstrategyblog.com). SWOT Analysis Strengths: 1. Brand equity 2. Product distribution and worldwide network 3. Solid financial performance 4. One of the worlds most recognized brand. 5. Innovation Weaknesses: 1. Credit rating 2. Customer concentration, particularly in the US (Wal-Mart accounts for more than 10% of Coca Colas business in the US) 3. Does not enjoy the number one position in India, Pakistan. Opportunities: 1. Possible growing demand. 2. Expansion reaching all segments. 3. Globalization 4. Catering to Health Consciousness of People 5. Bottled water growth Threats: 1. Health Drinks Fruit Juice Companies 2. Key competitors (Pepsi, etc) 3. Commodity prices growth 4. Image perception in certain parts of the world (case study Coca Colas strategy, www.thecoca-colacompan). Driving Forces I think the first driving force for the company is customer demand. If there is no demand it is meaning in producing the product. So for the Coca Cola, driving force is customer demand. The second one is innovation. Nowadays companies have to be able to survive and grow in an ever-changing market. In order to achieve these they should systematically innovate and deliver new products.   According to Companys late 90s earnings growth of 15-20% per year, turned in three straight years of falling profits.   It was apparent that the market was changing  and for keeping up these changes, Coca-Cola had to move from a single core product to a total beverage company.   This was a major change because their past success was base on having one successful core product.  Now Coca-Cola offers nearly 400 different products in and is still dominating the beverage industry.   The third driving force is globalization. Todays big business takes place on a global scale, and Coca-Cola is no exception.   Technology is continually changing business, and these constant changes have been making it more feasible and profitable for businesses to expand their operations globally in order to serve all different types of diverse markets around the world.   Coca-Cola is taking advantage of the large revenue opportunities made possible by participating in a global market and now offers products in 200 countries around the world.   Issues In my opinion the main issue of the Coca Cola Company is still producing its Coca Cola Classic product, which contains high levels of sugar and caffeine is causing a recent uproar on our increasingly health-conscience world.   There is a possibility that obesity concerns may reduce demand for some of their products.   In addition, the most amounts of its products are selling in the schools so this puts the pressure on Coke to provide healthier alternatives to their drinks if they want to keep selling in schools. The next problem is the Indian parliament has banned the sale of Coke products in its cafeteria. The ban came as the result of tests, including those by the Indian government, which found high concentrations of pesticides and insecticides, including lindane, DDT, malathion and chlorpyrifos, in the colas, making them unfit for consumption. Some samples tested showed the presence of these toxins to be more than 30 times the standard allowed by the European Union. Tests of samples taken from the US of the same drinks were found to be safe. As we know water is rare resource and today one of the main problems of the world is water shortage. This creating the problems in most companys operations and Coca Cola is no exception. The Companys bottling operations are facing severe shortages of water as a result of the cola major sucking huge amounts of water from the common groundwater source. To add insult to injury, the scarce water that remains has been polluted by Coca-Cola as a result of its operations. It is resulting thousands of Indian people protesting against the company. Conclusion and recommendations Though Coca Cola is performing well and gaining trust of its consumers and obtaining new consumers trust every day, it should act even better to keep its current position in beverage industry and keep on growing. The Company should increase its shareholders wealth by increasing its sales and decreasing the costs which will result higher earnings and net profit. As conclusion of analysis I have done, I suggest the following recommendations for the Coca Cola Company: Today everything is rapidly changing and companies for surviving should go step by step with those changes. The innovation gives the company key advantage among its rivals. So Coca Cola Company can introduce a new product, which many people will want to try. Coca Cola needs to continuously strengthen its brand to maintain brand loyalty and differentiate itself from its competitors, in order to maintain its strong market position. Reason of not being popular in India is the utilization of rear water resources. This put negative effect on the brand image, because of cola plant water level in the area decreases which makes the resident life miserable. If the Company wants a number one position in India they have to follow following criteria: Environmental due diligence before acquiring land or starting projects; Environmental impact assessment before commencing operations; Ground water and environmental surveys before selecting sites. Another major asset to a company of this size and clout is maintaining continuity among the workforce.   This is essential to keep the company in a positive direction, accomplishing common goals and constantly setting new goals.  

Napoleon Was NOT a Son of the Revolution Essay -- European History

At the end of the French Revolution, the hopes of the early stages of the Revolution had been mangled, leading into the Reign of Terror. France had dissolved into anarchy, with internal and international turmoil. It was out of the foreign wars that Napoleon came to power. Napoleon Bonaparte rose to power, victory by victory, eventually making himself Emperor of France, creating a strong central government while continuing the foreign wars, creating a mass French Empire. Although Napoleon was a product of the French Revolution and maintained the image as a â€Å"son of the Revolution,† idealism always fell to pragmatism as Napoleon’s main purpose was creating a strong unified France. Napoleon’s policies reflected some of the ideals of Enlightenment thought and he sought to spread them across Europe as he conquered. One of the core beliefs of the Enlightenment is that the universe is orderly and that there are natural laws that apply to everyone. Although what these rights were was up to debate, the central idea was that everyone should have them. As Napoleon conquered Europe he applied the same laws to everybody, everywhere. This set of laws is known as the Code Napoleon. Some of the laws enforced by the Code Napoleon can be seen in Napoleon’s Imperial Decree at Madrid, where Napoleon abolished feudal rights, such as banalities, as well as seizing church lands to be distributed among the people. Other actions he took were creating â€Å"constitutions† that created laws that applied to all people equally and could not be altered on a whim. These are the same actions taken during the French revolution applied to all other areas. In fac t, the promises of these reforms gave Napoleon’s forces supporters in the countries he sei... ...gery he used. Napoleon’s rule was greatly influenced by the Enlightenment ideas, but he was not a â€Å"son of the Revolution.† Louis Bergeron considered Napoleon an enlightened despot, saying, â€Å"the dynamism of Bonaparte and his rigorous administration revived the experiment of enlightened despotism, somewhat belatedly, since in the setting of Western Europe it was already a bit out of date.† Napoleon did resemble an enlightened despot as he upheld absolute power while encouraging legal and social equality for all classes of people (that weren’t him). What makes Napoleon unique among enlightenment despots is that he formatted his image to appear to be something else. The discrepancies between the image he presented and the person he was creates room for interpretation as to whether Napoleon was a dictator, an enlightened despot, or a champion of the revolution.

Bowlby’s Ethological Attachment Theory Essay

Abstract Bowlby’s ethological attachment theory bases its argument on the premise that human individuals, just like animals have a tendency to have a natural inclination to establish and maintain lasting affectionate bonds (attachments) to the familiar and irreplaceable others. Bowlby further asserts that once the attachments are established, the strength, and stability of the links is related the emotional stability and well-being of the individual throughout life. Bowlby proposes that the attachment initially form during infancy and often involve one primary attachment figure (mostly the mother or other primary caregiver). However, growth from childhood to adulthood results in the development of other secondary and multiple attachments which are organized into hierarchies from the most accessible to the least accessible. This forms the lifespan development of an individual as attachment needs for comfort and closeness shift from parents to peers as part of a healthy lifespan development. This paper discusses Bowlby’s ethological attachment theory as a theory of lifespan development. The paper is organized with an introduction which briefly discusses the concept of ethology and its ancestry from the study on the graylag geese by Konrad Lorenz. It further presents the contributions of Bowlby and the applications of the theory on human beings lifespan development and contemporary practice. The paper logically ends with a conclusion. Introduction Ethology emphasizes that human behavior is tied to evolution and biology, and is therefore characterized by critical periods. According to ethnologists, the critical periods are time frames during which the presence of lack of certain experiences exerts long-lasting influence on human individuals. The concept of ethology rose to prominence after a European zoologist (Lorenz) undertook a behavioral study on graylag geese and their behavior of following their mothers immediately after they hatch (Marga, 2011). In his  attempt to study on attachment, Lorenz subdivided the eggs laid by one goose into two groups with one being given to the mother for hatching while the other was hatched in an incubator. The goslings hatched by the mother followed the mother immediately after hatching while those hatched in the incubator followed Lorenz sine he was the one they saw immediately after hatching. Even after marking the goslings and placing them in a box, the goslings run to the mother and Lo renz according immediately after the box was opened (van der Horst & van der Veer, 2009). Lorenz described the process as imprinting. Imprinting refers to the process through which rapid, innate learning takes place and involves the creation of attachment to the first mobile object visible to a newly hatched gosling. John Bowlby took the concept ahead illustrating an application of ethological theory on human behavior and development. In his view, attachment to a caregiver during the first year of a child has significant consequences throughout the individual’s lifespan. In his words, attachment influences human relationships â€Å"from the cradle to the grave† (Pitman & Scharfe, 2010, p. 201). Bowlby argues that if the attachment is both positive and secure, the individual has a high likelihood of developing positively through childhood and into adulthood. On the other side, if the attachment is both negative and insecure, the individual has high chances of not attaining optimal life-span development. It is the concern of human individuals that they reach optimal lifespan development, something that ethological theory partly tries to explain. This paper discusses Bowlby’s ethological attachment theory and its applications in the course of lifespan development. Bowlby’s perspectives on ethological attachment theory From the perspective of ethological theory, babies have an innate biological preparation to participate actively towards the establishment of a bond with caregivers. The ethological theory holds that such an attachment promotes the likelihood that the genes of individuals survive (Makulincer & Shaver, 2012). The theory also posits that the behaviors of children are best understood in the context of their adaptive value hence they seek to fully integrate with the entire organism-environment arrangement. This includes physical, social as well as the cultural aspects an individual is exposed to in the course of life-span development. While Bowlby’s ethological theory  places its emphasis on genetics and biological aspects of development, learning also plays an integral role in life-span development since it facilitates flexibility and adaptation of human behavior. One of Bowlby’s concerns had to do with the ability of children raised in other institutions such as orphanages to form lasting relationships. Bowlby’s proposal was that children who grow up in institutions such as orphanages have difficulties when it comes to love because they never had the opportunity to establish attachments to a mother figure in the early stage of their lives. The attachment, in Bowlby’s view, is an emotional bond established between two people and this attachment is vital in the building of healthy relationships (Makulincer, Shaver & Berant, 2013). He argued that the bonding process starts at birth and runs through to later stages in life. Below six months, the infant is attached to the primary caregiver. Between six to eighteen months, the separation of the child from the attachment figure upsets the child causing frequent cries. Another accompanying behavior at this stage is the fear of strangers. While infants develop a primary attachment to a single caregiver, researchers also argue that other significant attachments also develop. Such attachments include those with siblings, fathers, and other close figures who interact with the child. Mary Ainsworth, an American scholar to study the area of attachment describes the attachments as secondary attachments (Marga, 2011). She further describes secondary attachments as important bonds in the life-span development of an individual. These attachments are vital since the child has to live in world beyond the mother/primary caregiver. Secondary attachments help in the transformation of the child from the comfortable symbiotic relationship that he/she initially forms with the primary caregiver to include others in the society (Makulincer & Shaver, 2012). It is from this development that the child is able to develop age-appropriate independence and autonomy in the course of life-span development. Children imitate their models and the positive interactions with the caregiver promote a sense of identity and attachment. Children also develop multiple attachments as witnessed in Ainsworth’s secondary attachments (Marga, 2011). A father who is warm and affectionate towards the child becomes emotionally involved with the child and establishes attachment. Researchers also find that when sons feel understood by their fathers, they develop attachments towards, their  fathers. On the other side, when sons feel misunderstood by their fathers, they did not only feel afraid of them but also did not want to be like the male parent in the future. The lesson here is that paternal affection and understanding are key components that help in the promotion of positive relationships and attachments between a male parent and the child. According to Sable (2008), Bowlby’s ethological attachment theory is recognized as a lifespan developmental theory. The author further argues that it is relevant in the understanding of how early affection experiences exert influence on emotional and physical well being of an individual both in childhood and adulthood. The author specifically singles the importance of Bowlby’s ethological attachment theory in clinical practice as it helps in understanding clients’ distress and the carrying out of psychotherapy. Contemporary research on neurobiology of attachment extends the basis of Bowlby’s conception of an attachment behavior system and suggests that its functions are executed in the brain’s right hemisphere, specifically the right cortex (Sable, 2008). Just like Bowlby asserts that attachment system evolves on the need for protection from environmental dangers such as predation, the brain is also an evolving organ largely influenced by â€Å"nat ural selection† (Sable, 2008, p. 22) and later shaped by environmental experiences. It is from this realization that knowledge of attachment theories becomes invaluable in psychotherapy. Application of Bowlby’s ethological attachment in lifespan development According to Pitman & Scharfe (2010), the principles of attachment theory are distinctively visible in moments of distress or sickness when the individual feels that their survival is under threat. However, there are many other instances when attachment behaviors are manifest such as children’s first experiences in schools and day care centers. Pitman & Scharfe (2010) observe that during the first day in day care centers, children experience increases in cortisol levels and heart rates. In the course of an individual’s developmental lifespan, other incidences include airport separations when couples display attachment behaviors as well as distress irrespective of their attachment security. Knowledge of attachment is useful in psychotherapy. According to Pitman & Scharfe (2010), individuals with high attachment anxiety and avoidance experience greater physical symptoms in comparison with individuals who have low attachment anxiety and avoidance. The researchers  also report on the existence of an association between attachment anxiety and avoidance on one hand and depression on the other across varying age groups. These range from samples of children and adolescents, emerging adults, married couples, community samples in transition to parenthood, university samples, as well as clinical samples. The results indicate an association between higher attachment anxiety and avoidance with depression (Sable, 2008). The establishment of attachment with the therapists determines the effectiveness of a therapist in giving assistance to a client. Bowlby believes that the development of a new attachment with a therapist enables the therapist to assist the client in revising the story of the client’s life into a more consiste nt narrative. According to Sable (2010), the role of the therapist is to provide a springboard for change and this is possible through joint exploration of the painful feelings and the unhappy events that contribute the current emotional problems of the client. In order to win this trust, the therapist ought to become a relatively secure base where the client experiences safety and support. The therapist has to cultivate for this attachment through calming and soothing interactions although it may take some time before the therapist is accepted and felt as emotionally familiar and affectively accustomed to the client. One of the applications of Bowlby’s ethological attachment theory by clinicians is in the assessment of the client’s attachment style so that the clinician can regulate the therapeutic approach (Sable, 2010). The outcomes of a therapy process reveal that avoidant outpatients show minimal clinical improvements in comparison to the secure and anxious outpatients after individual therapy (Makulincer, Shaver & Berant, 2013). They also report that in a study carried out in a university program training clinic, avoidant attachment had an inverse relationship to psychotherapy outcome. Researchers agree that problems in the working alliance between clients and therapists partially mediate the avoidance-outcome association. In another sample of clients with eating disorders, avoidant-attachment was linked with dropout of group psychotherapy. Another contemporary application of Bowlby’s ethological theory is in the diagnosis of the reactive attachment disorder. Follan & Minnis (2009) investigate the cases of the forty-four juvenile thieves described as affectionless psychopaths. Out of the sampled ‘juvenile thieves,’ 86 percent had undergone through prolonged separation  from primary caregivers in the early stages of their lives apart from being placed under multiple care placements. Follan & Minnis (2009) find out that in their sample, 60 percent of children with reactive attachment disorder had been separated from their homes either resulting from neglect or other types of maltreatment. According to Bowlby, the experience of separation from primary caregivers was a key etiological factor contributing towards the development of difficulties in children. These findings lend credence to Bowlby’s ethological attachment theory in the diagnosis of reactive attachment disorder (RAD). While Bowlby’s ethological attachment theory receives worldwide support, it also faces some criticisms. One such criticism is its reliance on biology and evolution as the basis of development as well as the use of selective observations in naturalistic situations. Marga (2011) presents contradicting reports of a study involving 162 farm children where there was no relation between infant training on one hand and personality development on the other. As a result, the research er implores scientists to â€Å"quit blaming mom† as a dismissal to Bowlby’s ethological attachment theory. While the criticisms are there, Bowlby’s ethological theory receives widespread support and application as it relates to the lifespan development of an individual. Conclusion The behavioral development of a human being begins at birth and occurrences at the formative years determine the personality development of the individual later in adulthood. Many theories such as the behavioral and psychoanalytic theories explain personality development of the human individual. The quality of the entire human life is the accurate measure of effective lifespan development of the individual. Bowlby’s ethological attachment theory argues that human individuals develop attachments to primary caregivers that are affectionate and supportive. As individuals grow, they develop other secondary and multiple attachments with peers in order to get security as they interact with different environments. Bowlby’s perspective has received widespread acceptance although it has also been criticized for placing emphasis on biology and evolution. Nevertheless, the theory receives application in psychotherapy. Researchers report that clients are open up to therapists after they develop a feeling of security and attachment with the therapist. There is evidence that psychotherapy  outcomes also depend on the establishment of attachment between the client and the therapist. There is also a link between avoidant-attachment and dropout of group psychotherapy. The theory specifically helps in understanding the distress of clients in various stages in life and this facilitates positive outcomes during physiotherapy. There is further evidence that Bowlby’s ethological attachment theory also helps in the diagnosis of reactive attachment disorder. As individuals grow from childhood to adulthood, their attachments change due to changes in the environment, making Bowlby’s ethological theory a theory of lifespan development.

What Is Justic

What is Justice? Justice is defined in the dictionary as â€Å"the quality of being just; righteousness, equitableness, or moral rightness†. However it’s interpreted differently by different people what some people think is a just, others and disagree and believe otherwise. I believe justice is when some is held accountable for the atrocity they have committed. When it comes to the death penalty though many society believe it is just to murder someone for the crime they commit, it is my believe death penalty cannot be just.The purpose of punishment is to teach a lesson so that you can learn from your mistake. There are different forms of punishment for different crimes punishment is needed to discourage people from committing a crime. There is a positive and negative punishment. A positive punishment is when you try to help the person and help them understand and may sometimes include rehabilitation. The negative punishment is: killing the person and shaming the person. The Maori way is a positive way of punishment. And the Portion’s way is a negative punishment.In the â€Å"Maori Way† the punishment wasn’t bad like the puritan. In the â€Å"Maori way† instead of sending him to jail they gave him a second chance to change. In the Maori Way it more about in the justice side because they didn’t put him in jail or kill him they gave him a chance to pay back his grandmother by getting a job and cooking for her. in the Maori Way the kid learns from his mistake which is the whole point of punishment. The old puritan society the punishments dealt to those who committed crimes were harsh.The puritan’s punishment’s had shame in it as part of the punishment. In the novel by Nathaniel Hawthorne wrote â€Å"The Scarlet Letter† as a story shame and guilt, and how they affect people in the town. Nathaniel Hawthorne intended Hester Prynne's punishment to have to personify her guilt towards herself. It also shows how she responds to the guilt when she faced it. It is also expresses how often guilt can rip people apart from the inside out. The main protagonist was given a shameful punishment for committing adultery.In her case she was given a scarlet letter â€Å"A†. Puritans practice is very strict religion they believe that god has chosen who will go to heaven and hell from before birth and that the only way to ascend to heaven is to be the best person you can be. The death penalty is the short way out and it also does not solve the problem. By killing the person he/ she doesn’t learn anything for suffer. By killing someone will not bring back the person or really get you closer. And who are we do decide who gets to like or not.

Free Essays on The Republic

The Republic written by Plato examines many things. It mainly is about the Good life. Plato seems to believe that the perfect life is led only under perfect conditions which is the perfect society. Within the perfect society there would have to be justice. In the Republic it seems that justice is defined many different ways. In this paper I am going to discuss a few. First I am going to discuss the reason why Glaucon and Adeimantus see justice as being a bad thing and it is better to live a unjust life. Plato's elder brother Glaucon argues that the just man is only just because of the fear that he will get caught and punished or the fear of having a bad reputations. He explains this decision in the story of the two magic rings. The rings of magic would make a man invisible whenever he turns it on his finger. He believed that each man would act in the same manor. They would both break into houses unseen, and help themselves to whatever they wanted. The just man would no longer feel the need to be just. He would have two lifestyles one, being just in front of the eyes of the society and two being the unjust man invisible unable to get caught. Glaucon say this proves that people are just only because they find it necessary. Adeimantus another philosopher and Socrates elder brother brought up the fact that we should take a look at the kinds of things people actually say when they get praised justice and condemn injustice. Adeimantus explains by saying that fathers tell there sons to be just because of the good reputations and social prestige that attaches to justice. So it is not justice itself that is recommended, but rather, the respectability that it brings with it. He believes that the son will realize to be just is only worth it if you can get a good reputation. Unless you are truly just the gods will punish you but as we have learned from the poets the gods can be bribed so if you ... Free Essays on The Republic Free Essays on The Republic Most normal individuals in the modern world would assume that all books written, not published, by man are based on either a portion of the author’s imagination, an event (biased or non-biased) in either history or during the life of the author, a straight-out autobiography, or a generalized biography of another person they once knew. However, this philosophical novel fits none of the descriptions above. The book is actually an in-depth recording of a philosophy contest between Plato’s teacher Socrates and several other great philosophers. What is significant about this contest is that, in it, Socrates describes his personal view of a â€Å"perfect world,† and why justice is so important in the process of creating a civilized world. The novel was completed in 370 B.C., and it describes a strong debate between Socrates and five other speakers. The two main arguments that he illustrates in this novel are that a ruler cannot obtain more power than the state, and that a philosopher is best suited to rule a nation since he has the ability to maintain this balance. Also, Socrates claims that only the philosopher has traveled beyond the â€Å"cave† of worldly desires and temptations to discover what justice really is. Socrates’ first major argument is with Thrasymachus in Book I. The current debate lies on the pure definition of justice. Thrasymachus claims that there is only one principle of justice: the interest of the more dominant force. Socrates counters this argument by using the phrase â€Å"the stronger.† He claims that the ruler of a nation will not be aided, but harmed, by an unintentional command, in the long run. Socrates then builds his argument gradually by stating that the good and just man looks out for the interest of the weaker, and not for himself. Thrasymachus tries to counter Socrates’s argument by vaguely proclaiming that injustice is more gainful than justice. However, Socrates bravely explains that the just ...

Free Essays on Juvenile Courts

Juvenile Courts I. Brief History of U.S. Juvenile Courts The 1st juvenile court was established in 1899. However, it wasn’t until 1945 that all states has juvenile courts. In the mostly rural society of the 19th century, parents ,churches, and communities punished children who committed crimes. Children were typically disciplined by force, sometimes brutally. The urbanization that followed the industrial revolution in the last half of the 19th century posed particular problems for children. Many were subject to harsh conditions, including extensive poverty and child labor. At that time, children who got into trouble (whether by committing a crime or by being the victims of abuse or neglect) were often put to work or sent away to relatives. So-called â€Å"reform schools,† the precursors of modern juvenile halls, were also set up. The ostensible purpose of these schools was to change or reform children, in part by giving them skills and training. In fact, these facilities were often little more than warehouse type jails, some with deplorable conditions, where most of the learning that occurred was how to become a better criminal. Around the turn of the 20th century, many social leaders came to believe that reform schools were not working. They also began to understand children not simply as mini-adults, but as people with special needs who should be treated differently than adults. Consequently, the movement for a separate juvenile justice system began. As with adults, juvenile court goals are a mix of rehabilitation, punishment and community safety. Juvenile courts have traditionally considered child less dangerous and more amenable to rehabilitation the adults.

3 More Cases of Dangling Modifiers

3 More Cases of Dangling Modifiers 3 More Cases of Dangling Modifiers 3 More Cases of Dangling Modifiers By Mark Nichol In each of the sentences below, the subject of the main clause is not logically associated with the subordinate clause, so the former must be recast to begin with the noun or pronoun in the sentence that the latter applies to, or the sentence must be revised so that a subject that pertains to the additional information provided at the head of the sentence replaces the inapt noun or pronoun. Discussion following each example explains the unsuitably of the existing subject, and revisions demonstrate how the sentences can be repaired. 1. Broken by unresolved trauma, the apocalypse is slowly wearing her down. The person referred to, not the apocalypse, is broken by unresolved trauma, so she must be the subject of the main clause: â€Å"Broken by unresolved trauma, she is slowly being worn down by the apocalypse.† 2. As a valued customer of World Wide Wickets, we would like to extend an invitation to you to view some exclusive deals on our products. Because we is the first word that follows the subordinate clause, the erroneous implication is that the entity self-described as â€Å"we† is a valued customer of the company, so the sentence must be recast to place the entity â€Å"you† in that role; the â€Å"we† can safely be omitted: â€Å"As a valued customer of World Wide Wickets, you are cordially invited to view some exclusive deals on our products.† 3. Appearing on the cover of Time magazine in 1994, tales of his exploits on the job turned him into a local legend. This sentence implies that tales of a person’s exploits appeared on the cover of the magazine, but it was he himself who appeared on the cover, and the role of the tales in turning him into a local legend is a separate matter: â€Å"He appeared on the cover of Time magazine in 1994, and tales of his exploits on the job turned him into a local legend.† Want to improve your English in five minutes a day?

The role of the IMF in helping poor and debt-troubled countries Assignment - 1

The role of the IMF in helping poor and debt-troubled countries - Assignment Example Its major function is to maintain international monetary system, the system through which countries make international payments. It basically works toward providing a system that will enable foreign exchange among countries as it promotes investments and encourage a global trade that is balanced (Heakal 2010). Countries accumulate debts by borrowing from other countries or institutions especially when getting funds from outside seems cheaper and easier. This is done for the purpose of investment in areas such as factories, production of raw materials, and to acquire products that cannot be found within their borders. Borrowing is also done to overcome crises such as wars and natural disasters. There are two means of paying the debts; by simply paying what is owed from the outcomes of the investments especially when loans are invested and managed in viable projects, and by borrowing new loans when conditions are favorable, which is used to offset the older debt (Kocic 2014). The International Monetary Fund is one organization that lends a shoulder to countries with difficulties to pay their debts. These countries experience a situation where their imports and other income sources cannot balance off what they owe. These countries turn to the IMF for two reasons; through loans, the IMF provides an instant means to offset obligations to external lenders and other lenders (both private and public) such as the World Bank which only give loans to financially struggling countries that have agreed to loan terms with IMF. This puts the IMF in the role of a gatekeeper; for a poor country to get loans from other areas, they must first have a loan with IMF (Multinational Monitor Magazine, 2000). As stated by IMF (2014), when a country is experiencing trouble financially and is unable to pay debts, it puts the international financial system at the risk of instability. The loan is open to all member states regardless of their economic state; whether poor,

Why the Saudi Government has implemented banning exports of cement and Article

Why the Saudi Government has implemented banning exports of cement and explain the answer in terms of monopoly strategy - Article Example This ban in led to a 58 percent slump in the cement index and reduced profits for most cement producing companies. The decision by the Saudi government to stop and ban the exportation of cement was prompted by the soaring domestic prices of building and construction materials. In the subsequent discussion, we will attempt to identify and explain the cause(s) of such a shortage, and factor(s) leading to the imposition of the ban. In addition, we will assess the reasons for its partial uplift and subsequent reinstatement, how the government’s actions translate to monopolistic behavior. Finally, we will analyze the impact, and effectiveness of the monopolistic strategy on the economy and in particular in relation to the country’s projected economic growth. Despite being the highest producer of cement among GCC countries, Saudi Arabia has recently been experiencing cement shortages. This is because the manufacturing companies export most of their products to international market to fetch higher prices. The exportation of cements has grown steadily between 2004 and 2007. In 2006, the cement export volume was quoted as 2.26 million tones. Total production over the same period was estimated at 33.1 million tones against a local consumption level of 31.2 million tones. This translates to a shortage of approximately 0.36 million tones locally. These statistics show the total production of cement in Saudi Arabia was 33.1 million tons in 2006. However, the total consumption of cement in the same year was about 31.2 million tones (El-Quqa, Hasa, Desai, Rout & Gupta 2007, p. 9). Comparing the above statistics, it is evident that there has been a shortage of cement in the local market. Since this trend has continued, the government responded by banning exports of cement to alleviate the shortage in the local market. In 2009, the ban was partially lifted following an upsurge in demand in the Middle Eastern countries.

How Construction has evolved and developed to the current standards. (Re-word if needed) - Dissertation Example The regulations relating to buildings and their construction is fundamental to the health, welfare and safety of everyone who live in a building, work in a building at some time transact business in and around building. These individuals of course include the disabled for whom special requirements have been given. They also seek to promote the conservation of fuel and power and the prevention of waste and water (planning regulations research (SAIC 2007). communities.gov). Individuals spend approximately 90% of their time in buildings (SAIC 2007). In the UK, over one third of the carbon dioxide emissions come from buildings. The emission of carbon dioxide is very harmful to the environment and in order to protect the ozone layer we have to emphasise the importance of standards. Building Standards are fundamental to the health and safety of us all. In this regard the authorities are working hard to ensure that standards are achieved and continuously improved. Compliance and enforcement has become new issues as standards are being adapted to keep abreast with design, technology, materials and construction, as well as energy conservation issues. However, there has been increasing concerns with regards to the level of compliance, frequency, pace and increasing complexity of these changes. 2.0 The Evolution of Building Standards Construction standards have evolved overtime with frequent and more complex Building Regulations since the 1990’s. These changes relate to: Structure of buildings, Fire safety to both dwelling houses and other buildings, Site preparation and resistance to contaminants and moisture; Toxic substances; Resistance to the passage of sound; Ventilation; Hygiene; Drainage and waste disposal; Combustion appliances and fuel storage systems; Guidance and Supplementary Information on the UK Implementation of European Standards for Chimneys and Flues; Conservation of fuel and power to existing dwelling houses, other buildings, new dwelling houses and other new buildings; access to and use to buildings; Glazing – safety in relation to impact, opening and cleaning; Electrical safety – Dwellings; Materials and workmanship. 2.1 Old Trafford to Wembley Old Trafford was built starting from as far back as the 1900s when requirements were very barely significant. However, there have been major demolitions, modifications and additions since that time. The old roof pillars were replaced in 1965 with modern-style cantilevers. Changes were also made to focus crowd noise on the pitch. The final adjustment was made in 2004 in order to ensure that all spectators had seats. Old Trafford has aspects of the new standards based on

Are We Academic Capitalists Assignment Example | Topics and Well Written Essays - 750 words

Are We Academic Capitalists - Assignment Example The current trend of education is grounded on academic capitalism. Faculty and students are viewed in terms of generating revenue and commercial value. Capitalism includes the reshaping the organizational sites, professional workforce, and terms of academic responsibilities to achieve the goals of the academic capitalists. The United States school program is integrated with the monopolistic capitalism. The line between the public and private institution was unclear. To financially survive, schools trained students to fill the needs of industry. Faculty members are defined as managed professionals. The following cases show capitalism is permeating the academic institutions. Case1. An increasingly part time profession. In Eastern Oregon State College and other academic institutions, the academic capitalists to hire terminated full time faculty members as part time teachers. Later, the part time faculty was reduced to teach only status. Lastly, the same faculty member was retrenched. Ca se 2. An increasingly managed profession. In 1982, the President of Sonoma State University insisted he had to revise the current programs. The school had to resolve the declining enrollment issue.

The academe supports the corporate competitiveness by playing major parts in the knowledge-based global economy. The academe trains students to blend with industry by becoming industry’s future leaders or managers of major corporations. Likewise, schools train students to create products and processes to fill the needs of the business industry players. Basically, the major goal of schools is to fill industry’s need for global competitiveness. Academic capitalism includes the public colleges and universities’ investment in business ventures. The ventures include startup companies precipitating from the cooperative efforts of the faculty and student s. with the academic setup, the schools’ startup companies do not have to suffer the pains of unprofitable or unsuccessfully business ventures, unlike non-academic business ventures. Public support cushions the ill effects of unsuccessful business ventures. The schools serve the educational needs of students who can afford to pay their school fees. The students use grants, loans and other sources to pay for their educational trainings. The academic institutions’ implementation of a market model translated to a restructuring that benefits the professional and high technology

Technology and Human Error in Aviation Term Paper

Technology and Human Error in Aviation - Term Paper Example Thus, every sector in the aviation system must find all facets where computers may be leveraged on to their advantage. Use of Computers in Aviation Systems To most, computers are for games, research, online business, sending e-mails, or downloading and uploading files. But in the aviation system, computers hold the life of the crews and passengers. A small hitch on the computer’s program might result to an aerial accident. Computers have various uses in modern aviation. These may be used to design aircrafts with better capacity, performance, and state of the art equipments. It can spot the parts of the aircraft that need maintenance, repairs, and modifications. Computers can read the codes of the system that has malfunctioned. Moreover, it may identify the geographic location of the aircraft and monitors its flight, and process data and communication transmission between ATC (air traffic controller) and pilot, among air traffic controllers, and among flight crews. It may ensur e airport and aircraft safety against accidents, unpleasant incidents, and delays; and give automatic weather reports so as to warn pilots of the coming weather conditions. Technology allows for accurate calculations and computations useful in designing aircraft and saves important data on maintenance and inspection history and some other specifications related to the plane. These data are used to check if the plane is still fit to fly or not (Dhillion, 2007). Analysis of Human Error How tragic is the effect of human error in aviation? About 70 – 75% of aviation accidents are attributed to human-related errors (Hall, 2003). When one diverts from what is accurate, then that may possibly constitute human error (Dhillion, 2007). It is considered human error when one fails to do what is expected from him or her. Structures of error are developed to identify its origin and reasons according to these different perspectives by Weigman and Shappel (2003). The cognitive perspective ta rgets the pilot’s skill on decision-making and choosing strategies, ability to solve problems during flight, and capability to comprehend and respond to stimulus and commands on hand. To reduce the mental workload of the pilot and to avoid accidents, a checklist is advised. This is also a ground for skill-based and decision errors (Weigman and Shappel, 2003). The ergonomic perspective suggests that even if all the reports would identify human-related error as the primary root of accidents, in this systems perspective, it hardly or rarely points to human as the cause. At the start of developing and designing the system and equipment, human factors are already considered. Accidents occur when a mismatch transpires between man, machine, and the environmental components. Problems arise when there are stressors in the part of human like anxiety and hazardous attitudes (Weigman and Shappel, 2003).. Moreover, the behavioral perspective states that rewards, motivations to work safely , the threat of punishment for failures, and past experiences can greatly influence the performance of an individual. According to Reason (1997, 2000), people who violate rules are motivation-driven people. They need to be rewarded when they follow safety rule and the lack of tangible reward for this individual will tend him to twist or break rules. Although this is unacceptable logically,

Business Law and Ethics Essay Example | Topics and Well Written Essays - 500 words - 2

Business Law and Ethics - Essay Example Secondly, the Parol Evidence Rule states that the final contract, and the provisions within it, makes all the previous negotiations concerning the matter null and void. The final contract is considered the final piece of agreement, and is deemed to contain all the information that is necessary for the deal to take place effectively. Moreover, the Parol Evidence Rule not only includes previous oral negotiations and agreements, but also those, which were put in writing. Therefore, when the final contract is signed, previous agreements are nullified because it is considered to supersede all of them. If the furniture was not included in the final contract, then the company, which is selling the warehouse, does not have to hand over the furniture, unless it chooses to do so as a gesture of goodwill. When one considers the second scenario, it can be said that, despite the fact that the furniture is in the agreement, the provision for their transfer cannot be enforced because there is no agreement concerning the price of the mentioned furniture. This situation is brought about because the terms of the agreement concerning the furniture in the contract, are vague and were not conclusively considered. In order to enforce such an agreement, its provisions have to be reasonably certain concerning the issues that are within it. The rationale for this is to ensure that the provisions are put into effect with little or no disagreements concerning with the terms of transfer. In this case, the provisions of the agreement do not state the price of the furniture, although the transfer of such furniture is mentioned. This agreement can be interpreted as one that is undeveloped and as such, its character can be considered promissory (Salbu 209). This means that the agreement was not supposed to be implemented immediately and that it is in fact, supposed to be implemented at a future date after further negotiations, concerning the matter,

Phoenix Jones Character Analysis Essay Example for Free

Phoenix Jones Character Analysis Essay They say with age, comes wisdom. They say a tough life will build tough people. That the world, no matter how terrible it may seem or how bad things get, is only what you make of it. This has never been shown more so by Phoenix Jackson from Eudora Welty’s â€Å"A Worn Path†. Encumbered with age and poverty, Phoenix shows fortitude, cleverness, and a child-like view of the world while traveling to the city for medicine. Welty’s love of literature from her mother, and classic writing style with African American characters (Marrs) is clearly displayed in â€Å"A Warn Path†. Eudora Welty, whose life spanned most of the 20th century, represented the world of the deep American South in multiple genres. In stories, novels, and photography, the Pulitzer Prize winner was especially interested in the relationship of place to character. Her art explores the impact of place on the life of the individual depending on race, gender, and economic status, as well as the reverse influence of the individual character on environment, which is exeptionally displayed in â€Å"A Warn Path† (Marrs). In â€Å"A worn path† an elderly african-american woman, named Pheonix Jones, is up against the world on her way to town. Armed with nothing but her cane, she maneuvers through obstactle after obstacle, showing perseverence in the highest fashion through every disincentive that inhibits her journey. As such, her story depicts the Depression in the United States from the vantage point of a victim insufficiently represented in art—though a victim who, like the mythological phoenix her name evokes, resists annihilation, Phoenix transcends the abuse she experiences. This essay will explore Eudora Weltys character Phoenix Joness most exemplary traits. It will shine light on her fortitude, ingenuity, and light hearted view of the world. Provided along with Phoenixs traits is examples in which she shows each trait, with direct reference to â€Å"A worn path†. Imagine, having every bone in your body weakened with over seventy plus years of aging. You now have the bones of Phoenix Jones. Weakened, she struggles to get to town. Yet, still she keeps trecking over every obstacle thrown at her. This calls to merit her outstanding fortitude. At one point she encounters a barbed wire fence. With barbs glaring at her, hungry to put a halt to her journey, â€Å"There she had to creep and crawl, spreading her knees and stretching her fingers like a baby trying to climb the steps. But she talked loudly to herself: she could not let her dress be torn now, so late in the day, and she could not pay for having her arm or her leg sawed off if she got caught fast where she was. At last she was safe throught the fence and risen up out of the clearing,† (Welty 850). This is a fine example of her phenominal perseverance and fortitude, showing she was not only going to get through, but she refused to let that fence make even a scratch on her dress. And even before that, at the start of her journey, she already had shown her tremendous amount of determination. As she starts out on her journey she exclaims with a fiery attitude â€Å"Out of my way, all you foxes, owls, beetles, jack rabbits, coons and wild animals! Keep out from under theses feet, little bob whites. Keep the big wild hots out of my path. Dont let none of those come running my direction. I got a long way† (Welty 849-850). This shows that her mind is already set on getting to town and nothing is stopping her. These fine examples show the true, raw determination and fortitude within Pheonix Jones, showing that she may be frail, but she is anything but weak. There are few things that make true â€Å"good character†. Imagination is one of them. No one has better imagination than a child. A child sees the world as something different something better. Phoenix Jones clearly holds her inner-child within herself after all these years. After traveling a piece she decides to rest. â€Å"Up above her was a tree in a pearly cloud of mistletoe. She did not dare to close her eyes, and when a little boy brought her a plate with a slice of marble cake on it she spoke to him. â€Å"That would be exceptable,† she said† (Welty 850). Her imagination peeking forth, this shows even through her journey, she imagines a little boy giving her a slice of delicious cake, presenting that everything does not have to be serious. A little piece onward, she shows her enlightening imagination running wild again as she runs up on a menacing scarecrow that she gazes at from a distance. â€Å"Ghost,† she said sharply, â€Å"who you be the ghost of? For I have heard of nary death close by. † She found a coat inside that an emtiness, cold as ice. â€Å"You scarecrow† she said †Dance, old scare crow† she said, â€Å"while I dancing with you. † She kicked her foot over the furrow, and with mouth drawn down, shook her head once or twice in a little strutting way,† (Welty 851). Her fun loving child-like nature is highlighted through this passage, showing that she took a fear, and enlightened it when she found out it was a scarecrow, dancing with it, showing the trophy of imagination and optimism. Welty shows through Pheonix that imagination will never die, and that it is a precious tool to get over any obstacle. Further down the warn path, Phoenix is greeted by a discourteous hunter helping her up after she fell in a ditch in the wake of a nosy dog coming to investigate this strange intruder. This point is where she shows her cleverness and wit. As she is talking to the hunter, â€Å" Without warning, she had seen with her own eyes a flashing nickel fall out of the mans pocket onto the ground† (Welty 843), and she said nothing. As it continues the hunter runs off and she wittily bent over in his absence and â€Å"The yellow palm of her hand came out from the fold of her apron. Her fingers slid down and along the ground under the piece of money with the grace and care they would have in lifting an egg from under a setting hen†(Welty 843). As he later lies about having money to spare, this presents her wit, as she gained five cents from this brash traveller who has the audacity to later hold a gun to her head as a joke, which does not intimidate her, and only shows once again the fortitude previously stated in the last paragraph. As she gets to her destination, a clinic that she gets medicine from, she meets an attendant when she first walks in. She came to claim a bottle of medicine through charity for her grandson, which may just be a guise to get free medication, which in itself is a example of clever planning, the example I am using is of her interaction with the attendant. â€Å"Its Christmas time, Grandma,† said the attendant. â€Å"Could I give you a few pennies out of my purse? † â€Å"Five pennies is a nickel,† said Phoenix stiffly† â€Å"Heres a nickel,† said the attendant† (Welty 856). She persuades the attendant to give her a nickel, which in total gives her a dime, showing her witty resourcefulness. Whether she uses this ten cent for her grandson a windmill, or something else she wishes to buy, her adept skill and dexterity is presented as she uses wit and expierence to claim these precious boons. Pheonix Jones is a woman of many traits. From her perseverance to her sly inginuity, she uses all her characteristics to get through â€Å"A Warn Path†. She shows her child like perception in a way that eases the burdon of travelling. To the hills and back again seven times fold, her fortitude and will is an object of pure sovereinty over obstacles in her way and in her head. And with just a little bit of quick thinking and bamboozlement she was able to obtain a secondary reward from her journey, a skill that comes in handy throughout her life. Pheonix Jones is a pure, text book definition of strong.

Unified Power Quality Conditioner Engineering Essay

Unified Power Quality Conditioner Engineering Essay Abstract-The aim of this paper is to present a constant frequency unified power quality conditioning system(CFUPQC)which consists of an unified power quality conditioner(UPQC) extended by adding a frequency changer in between the shunt active filter and series active filter . The series active filter and shunt active filters mainly used to compensate the voltage, current imbalance and harmonics. The frequency converter is used to compensate the supply frequency when it varies beyond the power quality limit. The proposed configuration all converters are connected back to back on the dc side and share the common dc link capacitor. The simulation results are presented to confirm that the new approach has better performance than the traditional UPQC. Index Terms-CFUPQC, frequency changer, voltage source converter (VSC), Matlab simulink INTRODUCTION Uunifed power quality conditioner is an advanced concepts in the area of power quality control. The basic working principle of unified power quality conditioner is based on series and parallel power converters that share a common dc link [1].Unified power quality conditioner is used to compensate voltage sag, voltage swell [2] , current harmonics [3] it is also creates an impact on the reactive power [4] through shunt voltage source inverter and series voltage source inverter. In order to avoid the switching oscillation, a passive filter is applied at the output of each inverter. At the output of shunt inverter a high pass second order LC filter is allocated and the output of series inverter low pass second order LC resonance filter is allocated. UPQC controller provides the compensation voltage through the UPQC series inverter and conditioning the current through the shunt inverter by instantaneous sampling of load current and source voltage. The reference current are compared with the shunt inverter output current (,) and are fed to hysteresis type (PWM) current controller. There are some problems with PQC. As the supply frequency changes the UPQC will not compensate the voltage sag and swell and current harmonics properly. This happens due to the presence of LC filters at the Inverters output terminals. It is directly affected by the variation of supply frequency. Fig.1: Basic Configuration of Constant Frequency Unified Power Quality Conditioner (CFUPQC) Fig 1 shows the proposed improved configuration of constant Frequency unified power quality conditioner. This modified unified power quality conditioner concepts enables the PWM converter to perform not only active filtering purpose, also the function of frequency changer. The compensation principle of the CFUPQC will be described in the coming sections. The proposed unified power quality conditioner has to satisfy the following requirements. Reactive power is maintained at minimum value. The load voltage should be maintained at the rated supply voltage. Maintain the input current with very low harmonic content. Assure the supply frequency is permissible within the power quality limits .The simulations result will be presented to validate the proposed CFUPQC. frequency quality indices In order to characterize the power system frequency under normal operating condition the following indices are used Where fr is the rated frequency (50 or 60) Hz and f is the real frequency. The relative frequency deviation (2) The integral deviation during the delay required to ensure appropriate of clock synchronized to the electrical network frequency (3) According to the standard En 50160/2006rated frequency of supply voltage is 50Hz.Under normal operation conduction the mean value of the fundamental frequency measured over loss stay within the following range. 50 Hz+ 1%.ie 49.5-50.5Hz for 99.5%of the year 50 Hz+ 4%.ie 47-52Hz for 100%of the time. But as power frequency may not be exactly 50Hz within the time interval. The fundamental frequency output is the ratio of the number of integer cycle counted clearing 10s time interval divided by the cumulative value of the integer value. The step taken to maintain the frequency with in required limits render deviation from the normalized value very rate phenomena. In this way an analysis is of the influence of frequency variation on the final customer is only for a reduced interval about +3Hz of the rated value and for rather short period. Within the reduced variation field (40%)a considerable number of static customers are not affected by the system variation(rectifier , resistance, ovens, electric arc ect)but 60%of the consumers (fans, motors ect)affected by the frequency variations. The asynchronous and synchronous driving motors connected the supply network used extensely in individual acceleration have the power frequency changes. Depending on the mechanical characteristic spee d of the motor and also depends on the supply frequency [13].The speed of asynchronous motors or synchronous motor unlimited drags to the electric power supply variations s proportional to the applied voltage frequency. The frequency variation leads to the correspond modification of the process production time throughout the supply with a reduced frequency depressing the supply frequency capacitive circuit, transformer, relay coil are affected Constant Frequency Unified Power Quality Conditioner (CFUPQC) CFUPQC structure Fig.3: Proposed Configuration Modified configuration of UPQC consist of shunt active filter, series active filter, voltage source inverter and voltage source converter shown in Fig(3).CFUPQC similar to the UPQC expect the frequency changing section. UPQC has the potential drawbacks in the hybrid filtering performance. Since its filter in characteristics depends on load impedance and supply frequency. CFUPQC series active filter is used for compensation the voltage harmonics and voltage imbalance In addition the voltage source converter supplies the AC to DC power and is fed to common DC link. The CFUPQC consists of parallel active filter (PAF) that eliminates load harmonics and compensates load reactive power. The control equation is Ipf=G.IL (4) Where g is the control function, is fundamental frequency.IL is the load current, Ipf is the parallel filter input current components for compensation are extracted from load current and load voltages using theory while the converter is a current controlled device using 20 kHz clocked hysteresis band. Series active filter (SAF) that compensates supply harmonics flicker, voltage sag/swell, unbalance and diode + capacitor type load harmonics to flow in to the parallel filter. Control equation is comp (5) Where k is regulator gain, Usf is the series filter voltage, Ish are harmonic supply current and Ucomp is compensation voltage needed to remove supply voltage imperfection. Ish are extracted to theory. Active rectifier (AR) for real power transfer to/from common DC bus and for DC bus control. Switching losses and power received from the dc link capacitors through the series inverter can decrease the average value of dc bus. Other distortions such as unbalanced conditions and sudden changes in load current can result in oscillation in dc bus voltage .In order to solve the fluctuated dc voltage the three phase rectifier is used .DC bus voltage is maintained constant using three-phase rectifier converter for bi-directional power flow and is controlled in such a way that it is insensitive to supply voltage imperfections. Rms value of the output voltage Vorms=0.9558Vml Rms value of the output current Iorms=0.9558Iml Where ml is maximum value of line current. Multi stage 48 pulse voltage source inverter (VSI) supplies the constant power frequency when the supply frequency will change. Here multilevel voltage source inverter is used, to eliminate the harmonic component of the output. The frequency converter is placed in between the series and shunt active filters. Normally the voltage source converters (rectifiers) generate the current harmonics. In order to avoid the harmonics and reactive power the rectifier is placed at the middle of the two active filters. Similarly if the load is increased voltage dip may occur in front of voltage source inverter. At the same time series active filter compensate the voltage problems. Control system of the CFUPQC shunt Part Fig.4: Control System of the Shunt CFUPQC 1) CFUPQC shunt inverter control system: In the Fig (4) shows the shunt inverter controlling block diagram of CFUPQC using synchronous reference frame theory where the sensitive loads current are . The measured currents of load are transferred in to frame using sinusoidal functions through synchronous reference frame conversion. The sinusoidal functions are obtained through the grid voltage using phase lock loop(PLL). Here the currents are divided in to ac and dc components (6) (7) The equation (6) and (7) and are the real and reactive components.ac components and dc elements can be derived by low pass filter.are the dc components and are the ac components of . The control algorithm corrects the systems power factor and compensates all the current harmonica component by generating the reference currents given in equation = (8) = (9) The reference current is transferred in to frame through reverse conversion of synchronous reference frame. Resulted reference current () and the output current of shunt inverter () are fed to the hysteresis band controller. Now the required controlling pulses are generated and the required compensation current is generated by the inverter applying these signals to shunt inverters power switch gates. 2) CFUPQC Series Inverter Control System Fig.5: Control System of the Series CFUPQC 2) CFUPQC series inverter control system: Fig (5) shows the CFUPQC series inverter controlling block diagram using synchronous reference frame theory. In this method the desired value of load phase voltages in d axis and q axis is compared with the load voltage and the result is consider as the reference signal. The supply voltage detected is detected and transformed in to the synchronous reference frame using (10) The compensating reference voltage in the synchronous reference frame is defined as (11) The compensating reference voltage in (11) is then transformed back into the reference frame .Resulted reference voltage () and the output current of shunt inverter () are fed to the hysteresis band controller. The required controlling pulses are generated and the required compensation voltage is generated. 3) Control system of 48 pulse voltage source inverter: 48-pulse voltage source converter consists of four three phase, 3-level inverters and 4 phase-shifting transformers creating phase shift of +/- 7.5 °degree. This transformer setup neutralizes all odd harmonics up to 45th harmonic. Eight 6-pulse inverters are combined to obtain a 48-pulse with the purpose of reducing harmonic content. Table 1 shows the values of phase shifts which are applied to the inverter voltages in two steps, namely in firing pulses and in Zig-zag transformers, to create a 48-pulse waveform at the output . Table 1:48 Pulse voltage source Inverter Coupling transformer Gate pulse pattern Phase shifting transfer Y-Y +11.25 ° -11.25 ° Δ-Y -18.75o -11.25o Y-Y -3.75o +3.75o Δ-Y -33.75o +3.75o Y-Y +3.75o -3.75o Δ-Y -26.25o -3.75o Y-Y -11.25o +11.25o Δ-Y -41.25o +11.25o content in the order of n= 48m ±1, where m= 0, 1, 2. The main-inverter intermediate-circuit capacitors together have an energy storage capacity of only 15 J/kVA. An output switching frequency of 1 kHz is chosen, which is fairly reasonable for this converter. Input is a frequency reference, which is passed through a rate limiter in order to be within the limits of maximum acceleration. Fig.6: Control System of the Frequency changer CFUPQC Except for the 23rd and 25th harmonics, this transformer arrangement neutralizes all odd harmonics up to 45th harmonic. Y and D transformer secondarys cancel harmonics 7+12n (7, 19, 31, 43,)and 5+12n (5, 17, 29, 41,) .In addition, the 15 ° phase shift between the two groups (Tr1Y and Tr1D leading by 7.5 °, Tr2Y and Tr2D lagging by 7.5 °) that allows cancellation of harmonics 11+24n (11, 35,) and 13+24n (13, 37,). Considering that all 3n harmonics are not transmitted by the transformers, the first harmonics that are not canceled by the transformers are therefore the 23rd, 25th, 47th and 49th harmonics. By choosing the appropriate conduction angle for the three-level inverter (ÏÆ' = 172.5 °), the 23rd and 25th harmonics can be minimized. Using a bipolar DC voltage, the voltage source inverter thus generates a 48-step voltage approximatly a sine wave. The secondary sides of the coupling transformers are connected in series to sum the output voltages of individual VSIs and resul ts in a multi-pulse phase voltage which can be expressed mathematically as follow (12) Both equations (12) and (13) which are phase-to-phase and phase-to-neutral voltage representations, respectively, show that harmonics up to 47th order are inherently filtered. The signalization of the 48-pulse inverter are generated for the inverter having -41.25 of gate pulse phase and directly fed to the corresponding inverter. PWM signals for the remaining inverters are obtained by applying relevant phase shifts to the set of PWM signals generated. For example, in order to obtain the pulses for the inverter having -11.25o of gate pulse +30o of phase shift is applied to the closed loop current controllers output. In practice, the phase shifting of the pulses is realized by applying a delay in the first cycle. The generated set of pulses is the earliest set appearing at the time-line and since it is not possible to apply a negative delay the earliest appearing set is generated and the rest are delayed accordingly. When the supply frequency is exceeded beyond the power quality limit the constant frequency voltage source inverter control system change the load from source power supply to the constant frequency inverter power supply. Simulation Results The proposed system, simulation results is simulated by MATLAB software. Fig 7Current harmonic minimization when the supply frequency is normal In the above simulation some capabilities of UPQC to solve power quality problems are shown. The nonlinear load which is produced harmonic current to the network. Fig. 7 shows that the shunt part of UPQC compensates these harmonics Components when the supply frequency is normal. Now assume that a deep and unbalance voltage sag, as occurs at t = 0.2 s to 0.25 s and voltage swell occurred 0.26 and lasts for 0.3 second. Fig.8. Sag swell condition when the supply frequency is normal In Fig(8) the UPQC inject the compensation voltage via series inverter and compensate efficiently at 0.2 second sag condition and voltage swell condition at supply frequency normal (60Hz) Fig .9.Series UPQC when the frequency exceed the power quality limit In fig 9 shows the operation of UPQC when the supply frequency exceeds the power quality limits the output was not found satisfactory .The supply beyond the power quality limit (greater than 63 Hz)at 0.25 second the load voltage waveform varies. The frequency increase rapidly the voltage waveform highly distorted as shown in the simulation results Fig 9. Based on the simulation result Fig 10 it is intended that if the supply frequency varies greater than power quality limit the load current wave form is distorted. If the frequency increases the wave form also distort rapidly as shown in fig10. Fig 10. CF- UPQC Operated when Frequency greater than the Power quality limits Fig 11. CF- UPQC Operated when Frequency greater than the Power quality limits Fig 11showsthe proposed CFUPQC model was simulated for a period of 0.01 sec to 0.5 sec from the results in fig 11, it was seen that at 0.28 sec the supply frequency crossed the power quality limit at 0.29. Fig.12. CF-UPQCs inverter supplying current under over frequency condition The above simulation shows the 48 pulse inverter carries the load current when the supply frequency varied beyond the power quality limit. When the frequency exceed the limits at 0.28 sec. the voltage source converter supply the power. The above simulation result Fig(13) clearly shows when the frequency changes the asynchronous motor speed also changes and the UPQC also not deliver the voltage sinusoidal. In this case the load connected in to paper mills, relays are affected. Fig.13. UPQC connected asynchronous motor under over frequency condition Fig.14.
