The Meaning of Health and Illness in the Mexican Culture Essay

The Meaning of Health and Illness in the Mexican Culture - Essay Example Without a doubt, health can be deeply understood in terms of a combination of biological, cultural and social factors slightly than with the sole purpose in biological terms. As it was stated above that the complete health image can be understood more deep by diverse of factors. No one can deny that the social influence on health is significant, where the better health and higher quality of life of community members depend on the level of their participation in the social networks, assistance to each other and overall change of the society to become more healthy and prosperous. Such social networks usually include the family, friends, neighbors, church, work, sport clubs and other social groups where people can exchange information, experience and advices. For Mexican people, health is seen as holistic issue or a unity between mind, spirit and body. In the West, the doctor hopes to "cure" a problem after people are unbearably sick, when they are in pain or feel physically disruptive symptoms. A traditional Mexican practitioner, by contrast, seeks to prevent disease by keeping all systems balanced and finely tuned throughout the patient's life span. Consultation with the practitioner of acupuncture is ideally an ongoing part of every patient's life. Although the idea of preventive medicine (for instance, prenatal care) is prominent in current discussions about revamping our medical care system, there is really no comparison to the prevention that is accomplished through acupuncture and herbs. illness also comes from a gradual blocking and deficiency of body energy. Mexican people see the body threatened by lifestyle factors such as overeating or overworking. We also look for disharmonies of the internal nature in intensely prolonged emo tional states such as grief or depression (LaVeist, 2005). Mexican culture and gender have their own influences on health care since the person's socioeconomic status, ethnicity, gender and other factors directly affect his/her perception of the disease, necessity or financial ability to seek appropriate treatment. It is obvious that those people who live in poverty or from low socioeconomic status receive less medical help than those with stable income and medical coverage. In multi-ethnical communities the doctors can influence the patients by learning and understanding the beliefs, attitudes and experiences of patients from different ethnical groups and nationalities. The influence of gender on health care can be observed while analyzing the female and male patients, their attitudes and behaviors, where men are usually direct and logical decision makers and women are less independent and more influenced by others (Chabram-Derners, Torre 2008). While some symptoms are obvious both for the person him/herself and others around (nervousness, physical dependence on alcohol or drugs, etc), other symptoms are rather difficult to recognize. Usually, people use schemas as the organized ways to look at things and people that influence person's expectations, behavior, etc. Certainly, to seek medical treatment is the responsibility of each drug-dependent person or those who surround him based on the perception of the severity of the addiction symptoms. Though, there are some factors that might positively influence treatment seeking, including belief systems, certain life activities, gender, SES and ethnicity. While the good patient role presumes that the person behaves well and properly by following the prescribed treatment and medical services, the role of bad

Efforts to Reduce the Budget Deficit Essay Example | Topics and Well Written Essays - 750 words

Efforts to Reduce the Budget Deficit - Essay Example Indeed in line with the conventional analyses, the United States has been a clear example of how disruptive an increasing debt deficit is to the long-term economic growth. The national debt has not only suppressed the overall national savings, which, in effect, has reduced domestic investments, but has also increased the country’s borrowing abroad, as evident in the current account balances. It is undeniable that sustained national debts over the years have played a lead role in increasing interest rates, making internal borrowing for investments expensive, hence the capital from abroad to finance the federal budget for almost every government that has ever been in place. As a result of the alarming successive decreases in the national income due to the huge returns from the domestic capital stock accruing mostly to the foreigners, a trend that has now erected caps on the national productivity via a mounting unemployment, several statutory budget controls have been enacted by the congress to reduce the budget deficit, with most notable efforts beginning in the year 1985. After years of disagreements between Congress and the President [Regan, to be precise] on either tax increases or spending cuts as a way forward in halting the trend of deficit growth, members of Congress from both sides of the divide finally passed the Balanced Budget and Emergency Deficit Control Act of 1985 [popularly known as the Gramm-Rudman-Hollings Act ("GRH")]. Passed and approved by the President as â€Å"an important step towards rectifying decades of fiscal failure† GRH laid down procedures of eliminating the federal budget deficit that stood at $200 billion in 1986 by the year 1991 (Stith, 1988). GRH was essentially a binding enactment, enforced independent of the legislative budget process and the executive orders, which had failed in cutting down the total government spending and/or resisting political pressure for more government programs. The celebration particular ly for President Reagan who had grander ambitions of reducing the share of the national resources consumed by the federal government was, however, short-lived, as the provisions of GRH was ruled a ‘violation of the principles of the separation of powers’ in 1986 by the Supreme Court in Bowsher v. Synar. To save efforts that went into making the GRH from complete collapse, the Congress went back to the drawing board, eliminating the constitutional defects identified by the Supreme Court eventually producing an amended version of GRH that moved automatic sequestration process from the hands of Comptroller General to the Office of Management and Budget (OMB) in the Office of the President (Stith, 1988). Accordingly, the deficits decreased in the subsequent years as a result of substantial cuts in spending accompanied by economic growth that ensured increased revenues. With the turbulent Bush administration in the 1990s, GRH proved insufficient in restricting the growth of the deficits. Congress, thus, reached an agreement with the regime allowing for a combination of â€Å"tax increases and caps on government spendin

The Walt Disney Company and Pixar Inc. Essay Example for Free

The Walt Disney Company and Pixar Inc. Essay To Acquire or Not to Acquire? In November 2005, Robert Iger, the newly appointed CEO of the Walt Disney Company, eagerly awaited the box office results of Chicken Little, the company’s second computer-generated (CG) feature film. He knew that, for Disney as a whole to be successful, he had to get the animation business right, particularly the new CG technology that was rapidly supplanting hand-drawn animation.1 Yet the company had been reliant on a contract with animation studio Pixar, which had produced hits such as Toy Story and Finding Nemo, for most of its recent animated film revenue. And the co-production agreement, brokered during the tenure of his predecessor, Michael Eisner, was set to expire in 2006 after the release of Cars, the fifth movie in the five-picture deal. Unfortunately, contract renewal negotiations between Steve Jobs, CEO of Pixar, and Eisner had broken down in 2004 amid reports of personal conflict. When he assumed his new role, Iger reopened the lines of communication between the companies. In fact, he had just struck a deal with Jobs to sell Disneyowned, ABC-produced television shows—such as â€Å"Desperate Housewives†Ã¢â‚¬â€through Apple’s iTunes Music Store.2 Iger knew that a deal with Pixar was possible; it was just a question of what that deal would look like. Did it make the most sense for Disney to simply buy Pixar? Walt Disney Feature Animation Walt Disney Feature Animation began with the production of Snow White and the Seven Dwarfs in 1934. Toys and memorabilia based on the movie’s characters were stocked in stores such as Woolworth’s around the film’s release, a move that became a trademark of Disney’s strategy. After many early successes, the animation division struggled for decades after Walt Disney’s death but  was rejuvenated with the arrival of Michael Eisner, as well as Jeffrey Katzenberg as chairman of Walt Disney Studios, in 1984. Under them, the studio produced a string of hit films that included The Little Mermaid and Beauty and the Beast, up to the enormous success of 1994’s The Lion King, which alone generated over $1 billion in net income for the company. The Walt Disney Company and Pixar Inc.: To Acquire or Not to Acquire? Eisner believed in making clear who was good at their job, and who was not so good, and wanted to give control to leaders who had a sense of judgment about creativity and business. Seventy-five percent of the time, he was able to find a director who had these skills and wanted to work on a particular movie; the rest of the time directors would be told to â€Å"just do it.†6 Katzenberg, who was known for his grueling work ethic and passion for animation, made it his personal mission to bring the studio back to its former glory. He supervised every aspect of the studio’s films. According to one former Disney executive, â€Å"Jeffrey is the sheep dog and the wolf. He’s the sheep dog guarding us, and the wolf hunting us.†7 Katzenberg was credited with hammering out the storytelling of each film and ensuring that each film had a moral resonance. He also brought on external talent to each movie, such as Elton John, who contributed songs for The Lion King. Recent Box Office Performance After The Lion King in 1994, every Disney-produced animated film fell below expectations (see Exhibit 1). When asked in 1997 about the division’s disappointing performance, Eisner replied, â€Å"I don’t think people quite understand our company. We have many avenues to make money from one of our animated films. The video revenues from one of our films are large, the consumer products huge.† Some of the same features that observers credited for Disney Animations’ success—large staff, large budgets, and lots of time—were also blamed for its demise. Disney Animation had just 275 employees in 1988; about 950 in 1994 for the release of The Lion King; and 2,200 at its peak in 1999.9 Competition for animators in the 1990s also caused salaries, which accounted for 80% of each film’s cost, to balloon, with top animators’ pay rising from $125,000 in 1994 to $550,000 in 1999.10 And these pay increases affected employees across the board. In 1994, Eisner refused to promote Katzenberg to president of the company, prompting his swift departure. The absence of Katzenberg, who was generally considered to be the studio’s creative force, struck many as the cause of the decline. As one commentator noted, â€Å"the company’s once-invincible animation studio has fallen on hard times since studio chief Jeffrey Katzenberg left.†11 In 1997, Katzenberg, along with Steven Spielberg and David Geffen, started rival animation studio DreamWorks. According to reports, in the years that followed, DreamWorks attempted to lure away some of Disney’s best animators. Joe Roth, former chairman of 20th Century Fox, became chairman of Walt Disney Studios after Katzenberg’s departure. In charge for six years, he focused the studio’s energy on live action films.13 Peter Schneider, former head of Disney Animation, took over in 2000 after Roth left. Schneider’s goal was to deliver â€Å"emotional, thematic stories.†14 He worked solely with established Disney directors and producers and relied on his younger development staff to broker deals with up-and-coming filmmakers, in contrast to the hands-on deal-making style of his predecessors, Katzenberg and Roth.15 The product development group assigned directors for each animated movie. In the late 1990s, Disney set up a â€Å"Secret Lab† in an old Lockheed plant near Burbank Airport as a response to the growing popularity of three-dimensional (3D) CG films. The group’s first CG project was the costly Dinosaur, which was released in 2000 to a strong opening weekend, but which ultimately disappointed at the box office. The Lab was shuttered in 2001 after Roy Disney viewed and rejected the second project underway, Wildlife, which he thought was packed with adult themes and strayed too far from Disney’s family-friendly brand offering. Disney then focused its animation efforts on traditional two-dimensional (2D) projects  such as 2001’s Atlantis: The Lost Empire.16 In 2002, under new feature-animation chief Thomas Schumacher, Disney embarked on an aggressive cost-cutting mission. Lilo Stitch, the first movie made in the new environment, cost about $80 million to make, versus $150 million for the 1999 Tarzan. Instead of 573 animators crafting 170,000 individual drawings, a crew of 208 rendered 130,000 drawings.17 Cost-cutting efforts took Disney’s animation department from its high to around 1,100 in 2003. At that point, as rival studios, such as News Corp.’s 20th Century Fox, exited the market, salaries slid precipitously. The market rate for the animator who brought home $550,000 in 1994 was half as much by the early 2000s.18 Apart from omitting redundancies, Disney Animation kept costs down by cutting corners where it could, in ways that were imperceptible to audiences. For example, the group eliminated things such as the number of characters seen in each frame or the amount of motion in the background.19 The televisionanimation unit also produced very low-cost films, like The Tigger Movie, which could make money with only $45 million in box office receipts, since the production cost was kept down to $15 million.20 In 2003, Disney Studios finally set up its own CG animation department. However, many staff members needed to be retrained in the new technology, which cost Disney money, heightened tension, and depressed morale within the studio. Disney decided to slow production on its animated films to give the staff more time to work on them and hammer out the story lines. American Dog and Rapunzel Unbraided, the second and third releases after Chicken Little, were both pushed back.21 Throughout this period, Disney came to rely on revenue and characters produced by its partner, Pixar. Between 1998 and 2004, Pixar CG movies contributed a total of more than $3.5 billion to Disney Studio revenues, and more than $1.2 billion to Disney’s operating income (Exhibits 2 and 2a). Pixar’s contribution represented 10% of revenue and over 60% of total operating income over the period. In 2005, Disney even set up a group known as Circle 7 to produce sequels to Pixar movies. The 40-person staff working on Toy Story 3 in March 2005 grew to 160 people during the followi ng year. Movie Economics While box office revenues from the theatrical release were the typical  measure of a movie’s success, financial success actually came from other revenue streams generated by the movie. By 2005, such sources included home video sales (originally on cassette tapes, but increasingly on DVD); payper-view and video-on-demand on cable channels; television showings, whether on free channels, such as NBC and CBS, or on cable channels; merchandise sales including toys, apparel, books, etc.; and video games and other electronic uses of the characters (see Exhibit 3). By 2005, the largest of these revenue sources was not theatrical box office but home video. Because character-related sales had such a long tail, revenue for a hit animated movie would come in over many years—up to decades for classic movies that were re-released theatrically and in home video form. Given the longevity of a great movie, film libraries were valuable assets. DreamWorks’ film library, for example, was about to be sold to Paramount for $900 million.23 Sequels to successful movies were another important source of revenue. The sequels to Toy Story, Shrek, and Ice Age, for example, generated between 30% and 90% more box office revenue than the originals. Once a character had been established, the existence of a built-in audience for subsequent  movies reduced marketing costs. Successful sequels would also extend the life of the original movie, particularly for animated features that appealed to successive generations of young children. Pixar Inc. Pixar was unusual among movie studios in generating a succession of box office hits. Its first five full-length films each grossed over $350 million.24 Steve Jobs said, â€Å"Everybody has tried to break into the animation market since Snow White was released in 1937. So far, only two companies  have ever produced a blockbuster production grossing more than $100 million, Disney and Pixar.†25 Pixar’s animation broke from the traditional model because the company did not use hand drawings but rather 3D computer-generated models. In 2D traditional animation, frames comprised hand-drawn cels, which required the skills of hundreds of people working for two to three years. Traditional animation constricted artists’ flexibility, too—if a change needed to be made to a character or scene, all subsequent frames had to be changed. Three-dimensional CG, on the other hand, used mathematical models to redraw each cel and mimic camera angles in ways that traditional an imation could not. Pixar used its own proprietary computer animation technology to generate incredibly lifelike 3D images and backgrounds, although CG still could not quite make human characters look perfectly realistic. Said Jobs, â€Å"We have 10 years of proprietary software systems that you cannot buy anything close to in the marketplace. You have to build them yourself.†26 Pixar’s technology allowed animators to manipulate hundreds of motion control points within a single character, to reuse animated images, and to edit easily.27 These technologies enabled Pixar to make animated films faster than its competitors and at a fraction of their cost. For example, the company made Toy Story with just 110 staff members, who spent the time saved on animation to focus on story and character development, as well as fine-tuning visual details. History Pixar traced its origins to the University of Utah in the 1970s, where a young Edwin Catmull studied computer science in a program renowned for creating the new field of computer graphics. Around the same time, Alexander Schure, president of New York Institute of Technology (NYIT), hired a team of animators to make a film version of â€Å"Tubby the Tuba,† a children’s record. Frustrated by the limitations of hand-drawn animation, Schure flew to the University of Utah, where he met and recruited Catmull to work at the Institute. Catmull and his hand-picked team spent four years at NYIT, where they made inroads into the field despite never producing the Tubby the Tuba movie. In 1979, George Lucas approached Catmull’s team with an offer to work on special effects for Lucasfilm, producer of the wildly successful Star Wars and Indiana Jones franchises. While working there in the early 1980s, Catmull met John Lasseter at a computer graphics conference and the two became friends. Lasseter, a young animator from Disney, had studied at California Institute of the Arts with the likes of Tim Burton. Skilled in art as a young boy, Lasseter read a book on the art of animation and Disney during his freshman year of high school and realized what he wanted to do with his life. After graduation, he joined the ranks at Disney and worked on Mickey’s Christmas Carol. He commented, â€Å"I felt that Disney was, at the time, doing the same old thing. They had reached a certain plateau technically and artistically with, I think, 101 Dalmatians, and then everything had been kind of the same ever since then, with a glimmer of characters or sequences that were special.†30 In 1984, Lasseter went to Lucasfilm’s computer division under Catmull. In 1986, Steve Jobs—who had left Apple Computer the year before—bought the Lucasfilm computer business, then called Pixar, for $10 million.31 Initially, Jobs intended Pixar to be a computer hardware and software company. He spent the next several years subsidizing the company to the tune of nearly $50 million from his personal funds. When the graphics computers did not sell, Jobs cut a third of Pixar’s staff in 1991 and left only the animation division.32 Jobs said, â€Å"If I knew in 1986 how much it was going to cost to keep Pixar going, I doubt if I would have bought the company. The problem was, for many years the cost of the computers required to make animation we could sell was tremendously high. Only in the past few years has the price come down to the point that it makes business sense† (see Exhibits 4 and 4a).33 Software Pixar initially developed three proprietary technologies: RenderMan, Marionette, and Ringmaster. In 1989, the company released RenderMan, a software system that applied texture and color to 3-D objects and was used for visual effects. Pixar used RenderMan itself and sold it to Disney, Lucasfilm, Sony, and DreamWorks, which used it to create effects like the dinosaurs in Jurassic Park. The program served as Pixar’s main source of revenue during the company’s early years. As of 2005, it had developed special effects for 100 films, and 44 of the last 47 movies that won the Oscar in visual effects had used RenderMan. In 2001, Catmull, along with two other Pixar scientists, won an Oscar for RenderMan and its advancements to the field of motion picture rendering. Marionette, the primary software tool for Pixar animators, was designed specifically for character animation and articulation, compared with other animation software that was designed to address product design and special effects. Ringmaster was a production management system used to track internal projects and served as the overarching system to coordinate and sequence the animation, tracking the vast amount of data employed in a three-dimensional animated film.

A Zara Supply Chain Strategy

A Zara Supply Chain Strategy The theoretical scope of this literature review is distributed by purchasing strategy and by supply chain strategy prospective. This part of the literature is founded on the Internet and from the articles in the Burch International University library. Through searching for the adequate informations, definitions, articles, journals etc; research was being executed with the keywords such as purchasing strategy or supply chain strategy or management or just Zara supply chain management. There are different datas, articles and web sites that were funded by the Internet about the Zara, and all offers different ideas of the research direction. In order to collect lot of useful and accurate material of Zara, I obtain from friend who works as a seller manager in Azel store. A Zara supply chain strategy was the key term of my research and was an important part of my theoretical focus on supply chain strategy. The aim of this research is to give a clear picture of the theoretical research and to be able to manage analysis of the Zara case study showing how company purchase and which supply chain strategy perspective is the most convenient for such a company. The purpose of use of review in this research is based on the explaining and verifying the role and impact of purchasing and supply chain strategy of the Zara industry and how its making successful. The effects of supply are particularly fundamental in fashion industries of marketing research. Although through this review also it will be described different aspects of supply chain points in the fast fashion industry. INTRODUCTION This review however will be based on the two sections; describing and analyzing the structure of the Zaras stores and on understanding the influence of purchasing of supply chain strategies. The manufacturing ZARA clothing company has an excellent development of supply chain, practical and innovative distribution channel processes. Brief description of supply chain management In usual supply chain management (SCM) is studied issue in marketing practices and theories as well. Supply chain management is a set of approaches utilized to efficiently integrate suppliers, manufacturers, warehouses, and stores, so that merchandise is produced and distributed at the right quantities, to the right locations, and at the right time, in order to minimize system wide costs while satisfying service level requirements. The supply chain management is the active management of supply chain activities to maximize customer value and achieve a sustainable competitive advantage. It represents a conscious effort by the supply chain firms to develop and run supply chains in the most effective efficient ways possible. Supply chain activities cover everything from product development, sourcing, production, and logistics, as well as the information systems needed to coordinate these activities. The organizations that make up the supply chain are linked together through physical flo ws and information flows. Physical flows involve the transformation, movement, and storage of goods and materials. They are the most visible piece of the supply chain. But just as important are information flows. Information flows allow the various supply chain partners to coordinate their long-term plans, and to control the day-to-day flow of goods and material up and down the supply chain. Zara Zara is one of the perfect examples of fast fashion industry. There are six moths time of waiting for training production supplier, while for the fast fashion industry it takes only four to eight weeks that have much faster speed of supply chain productions. However, Zara control to drop new lines into its stores floor twice in a week. The major success of ZARA Company is its dynamic supply chain with its specified outcome of focusing on a shortest response time. Using the supply chain management ZARA products generate its instant fashions being cheap, stylish and trendy by using a high wage form and it doesnt necessarily means poor quality. Therefore this means that the fast fashion industry involve requirements such as: low raw material costs, high productivity, low labor costs, good quality and mostly recognizing what the consumers wants of fashion products; which means it meets the customer satisfaction. Zara has developed a supply chain which is efficient of getting a trend from the catwalk from their stores in period of one month, while for four to twelve months from its company competitors. According to this the strategy of reducing the quantity manufactured creates scarcity. Thus, this is productive for Zara because of two reasons; first the less availability leads to highest desirability and from the secon d reason, with fewer amounts being produced in any time means that there is less to be added at the end of season sales. An overall discount of Zara is about 18% of its total operation range, where half of the level its competitors. In order to get their supply chain integration Zara operates with decent level of sharing data and integration between retailers, manufacturer and third party researchers as essentials. In addition Zara is able to accept cost source of the customer quickly, have close enough manufacturing so that fast trendy replacement can be competed, higher tools of technology which means faster market sampling test provide the opportunities to gather and analyze market response from new products for the suppliers and of course include the online retailing to provide quicker customer feedbacks on both products satisfaction and customer behavior preferences which needs to ensure that Zara sales operations are running successfully. All these characteristics means that the informations sharing can help so that supply chain move faster. In the case of Zara the time is one of the primary drivers to reach the competitive advantage, where an agile of supply chain management is created. Zara is being focused on the flexibility and market sensitive, until to comparisons of the ordinal method of being forecast driven. Presence of the ZARA in the fashion world has pressurized competitors of entering their supply chains to keep the track with Zara; therefore it does recognize the importance for the quick response. With quick response system Zara is able to respond its customers wants better than its competitors. ZARA industry is focused on the ultimate consumer with allocating a huge emphasis on implementation of backward vertical integration to perform the strategy into a fashion follower, before than to accomplish production efficiencies. Zaras accepts a quick response strategy communication that is effective expected to its management and collective culture. The continuous processes of information between managers provide the company to keep its customers satisfied, which in turn results in raising the sales. Furthermore, Zaras centralized issuing offer the chain a competitive progress by decreasing the lead-time of their goods. Reducing the time to increase the delivery speed transportation is scheduled by time zones and its loaded by way of air and place of land. The advantages of ZARA delivery time outside the Europe is around one or to two day approximately. Based on Zaras strategy centered on fewer advertising cost is one another advantages over its competitors. Investments advertising cuts minimize a total expense that makes the international expansion more profitable. According to this company relies mostly on its stores to project their image, so it is clear why Zara is familiar for its essential real estate locations. Nowadays people all around the world have far higher access in world fashion because as the result of the e-commerce and internet. Company of Zara recognize this and use it to their advantages by offering the latest clothing trends to their customers. However, Zara has a successfully developed business model which distinguishes itself from its competitors, (H,M, Benetton etc.) but it also has disadvantages that can have influence on its sustainable growth. Therefore there are some weaknesses that strategy of Zara creates. Furthermore, vertical integration is considered by many authors as a strategy which potentially raises profits and decrease risks, where the defects are still equally considerable to recognize. Thus, vertical integration often brings to the inefficiency to acquire economies of scale. Reflexive introduction and focus on speed of new products incurs increase costs as well. Hence they have greater research and development costs. Also they have increased costs due to th e constant transformation of production techniques to make out their different clothing lines. In general todays highly competitive fashion and apparel market place where quick changing of fashion trends forces the fashion industries to make responsiveness to the market need as much as possible. Supply chain strategy is a primary performance driver for these companies to attain the competitive advantage in the marketplace. Purchasing and supply chain management operates with the nuts and bolts in Zara industry. Implementing purchasing and supply strategies can help in saving the costs and in optimizing the ways in which companies integrate suppliers, manufacturing and transportation. In addition to this they used to increase response time in market over lead time reductions, provide availability and flexibility of supply in response to customer desires, and connect supply chain strategy with e- commerce in order to accomplish efficiency and profitability. The importance of improving the efficient customer and quick response is vertical information integration and adjustments over the supply chain with information and communication technology. Within the fact that it can control the entire supply chain closely to the better end, which gives opportunity to the company to be in position to produce the most trendy fashion styles roughly in real time to respond in the fast changing customers tastes. More accurate market information and update data are always needed to avoid unsold inventory and markdown cost as fashion and custom products are with volatile demand and highly unpredictable. An effective way of aligning right supply chain strategy is to match product unc ertainty. Postponement strategy can considerably reduce inaccurate forecast risk and do a responsive supply chain strategy. Zara has accomplished the benefits of agile and flexible supply chains for its innovative fashion items. Although, Zara overcome its competitors todays in terms of profit margins, without any stock out rates keeping the industry leader in the market. As a result the purchasing and supply chain strategy has a major role in this type of the company. The success of Zara is that it has attach the problem of the highly consumable fashion items in controlling and streamlining their supply chains so that they is capable to greatly decrease their lead time and thus to respond faster enough on the very fast changes in the fashion customer needs and wants in real time minimizing the fashion risks. Zaras excellent responsiveness to new fashion trends definitely needs to their optimal supply chain strategy.

Learning Case Adaptation :: Technology Case-Based Reasoning Essays

Learning Case Adaptation Computer models of case-based reasoning (CBR) generally guide case adaptation using a fixed set of adaptation rules. A difficult practical problem is how to identify the knowledge required to guide adaptation for particular tasks. Likewise, an open issue for CBR as a cognitive model is how case adaptation knowledge is learned. We describe a new approach to acquiring case adaptation knowledge. In this approach, adaptation problems are initially solved by reasoning from scratch, using abstract rules about structural transformations and general memory search heuristics. Traces of the processing used for successful rule-based adaptation are stored as cases to enable future adaptation to be done by case-based reasoning. When similar adaptation problems are encountered in the future, these adaptation cases provide task- and domain-specific guidance for the case adaptation process. We present the tenets of the approach concerning the relationship between memory search and case adaptation, t he memory search process, and the storage and reuse of cases representing adaptation episodes. These points are discussed in the context of ongoing research on DIAL, a computer model that learns case adaptation knowledge for case-based disaster response planning. 1 Introduction The fundamental principle of case-based reasoning (CBR) for problem-solving is that new problems are addressed by retrieving stored records of prior problem-solving episodes and adapting their solutions to fit new situations. In most case-based reasoning systems, the case adaptation process is guided by fixed case adaptation rules. Practical experience developing CBR systems has shown that it is difficult to establish appropriate case adaptation rules (e.g., Allemang, 1993; Leake, 1994). In defining adaptation rules, a key problem is the classic operationality/generality tradeoff that was first observed in research on explanation-based learning (e.g., Segre, 1987): Specific rules are easy to apply and are reliable, but only apply to a narrow range of adaptation problems; abstract rules span a broad range of potential adaptations but are often hard and expensive to apply because they do not provide task- and domain-specific guidance. In those CBR systems that do perform case adaptatio n, specific rules are often used, requiring that the developer perform difficult analysis of the task and domain to determine which rules will be needed. In practice, the problems of defining adaptation rules are so acute that many CBR applications simply omit case adaptation (e.g., Barletta, 1994). This paper presents a new method by which a case-based reasoning system can learn adaptation knowledge from experience.

Moving On With a Disability :: Papers

Moving On With a Disability 'Disability' something that disables a person, a physical incapacity caused by injury or disease. To me the word was somewhat closer to home. I am going on fourteen and am seated in a wheelchair permanently, I always have been. Cameron is the name, walking is the game. The wish more like. Being stuck in a wheelchair is very infuriating and when I am in that mood, just don't try and get me out. Talking of going out I don't. Well very rarely. I stay in my room most of the time with my books and my tutor. It is where I want to be. It is no-one's fault I am in this way and there is nothing anyone can do about it. I need to face facts; I am glued to the chair. " Good morning Cam!". He stood there like he did every morning at 9am sharp, but DiÃÆ'Â ¡z was not a sharp man. Messy struck me as more of the correct word. My tutor was in his mid thirties with short, brown hair. He hadn't shaved. Stubble the colour of cigarette ash clung to his jaw. His big round glasses bounced as he walked. His clothes were shabby and he often wore the same items for days running. DiÃÆ'Â ¡z was a good friend; my only friend and he shared my love of books. He often brought me a book from his collection. They were about all sorts but I liked the detective ones best. I wished I was Sherlock Holmes. Mind you I wished I could walk too but as Mum always says, ' Life does not come on a silver plate.' Well it should come on a gold one, that's what I think! I don't think you can understand what it is like not to be able to do something that everyone else can. I definitely don't think I can explain it! When I wake up, I cannot dress myself. How would that make you feel? Incompetent maybe? That's how it makes me feel. Everyone else can dress themselves, why can't I?

Causes Of Myasthenia Gravis Health And Social Care Essay

Myasthenia Gravis is an autoimmune upset, the immune system attacks portion of the organic structure. In MG that portion is the muscular system. The organic structure produces antibodies that mark receptors for the neurotransmitter acetylcholine on the musculus cells at neuromuscular junctions. Peoples with MG have a one -third the normal figure of acetylcholine receptors here. On a whole -body degree, this causes weak and easy fatigued musculuss. MG affects 100s of 1000s of people worldwide. Mostly adult females in their mid-twentiess or mid-thirtiess, and work forces in their 1960ss and 1970ss. The particular symptoms depend upon the site of onslaught. For 85 % of patients, the disease causes generalised musculus failing. Many people develop a characteristic level smiling and rhinal voice and have trouble mastication and get downing due to affected facial and neck musculuss. Many have limb failing. About 15 % of patients experience the unwellness merely in the musculuss environing their eyes. The disease reaches crisis degree when respiratory musculuss are affected, necessitating a ventilator to back up external respiration. MG does non impact esthesis or physiological reactions ( Shier, 2010 ) . Causes of Myasthenia Gravis The exact cause of MG is non known. One theory is the status may be triggered by a virus or other infection that has a similar construction to a portion of the acetylcholine receptor. Sometimes adult females with MG who give birth transmit these peculiar antibodies to their babes, doing musculus failing in the baby. This is called neonatal myasthenia and occurs in approximately 12 % of babes whose female parent has MG. â€Å" It is different from inborn myasthenia because the infant gets better in a few hebdomads as the antibody blood degrees go down † ( MediResource, 2013 ) . The other abnormalcy that frequently shows up in people with myasthenia gravis is an hyperactive, overlarge, or otherwise nonfunctional Thymus. The Thymus is a secretory organ located where the cervix joins the thorax. It is of import for the normal development of the immune system. Normally, the Thymus is larger in childhood than in maturity and becomes inactive around pubescence. In people with MG, nevertheless, it frequently keeps traveling into maturity ( MediResource, 2013 ) . Some people with MG turn out to hold a thymoma ( a tumour in the Thymus ) . This is a type of malignant neoplastic disease, but really few people die of thymomas ( MediResource, 2013 ) . The most common symptoms of MG are the dual vision which is called diplopia, every bit good as saging palpebras which is called ptosis, and musculus failing that normally gets worse after exercising or at the terminal of the twenty-four hours and improves with remainder. ` Swallowing troubles are of peculiar concern as they can be unsafe. MG typically does good at the beginning of a repast but tyre at the terminal, do get downing excessively hard. Some deteriorate to name where there is entire loss of ability to masticate and get down. At this point, nutrient may lodge in the pharynx, or nutrient and drink may get down to travel the incorrect manner, for illustration into the trachea, doing coughing and choking. Foods which may trip MG symptoms may be: Very hot, Spicy, Dry and britty Foods which require a batch of masticating attempt, such as tough meats or chewy Sweets, could besides pall out the myasthenic and cause trouble in get downing ( Boyce, 2013 ) . Many people with MG upset find it temporarily impossible to eat may hold to be admitted to a infirmary and be fed intravenously. Of more immediate danger is when the disease causes trouble in breathingaˆÂ ¦This is called a myasthenic crisis, and it ‘s responsible for most of the little figure of deceases due to myasthenia gravis. Peoples with take a breathing jobs must travel to a infirmary instantly. ( Boyce, 2013 ) How is Myasthenia Gravis treated? Today, MG can be controlled. There are several therapies available to assist cut down and better musculus failing. Medicines used to handle the upset include anticholinesterase agents such as Prostigmin and pyridostigmine, which help better neuromuscular transmittal and increase musculus strength. Immunosuppressive drugs such as Orasone, cyclosporine, and Imuran may besides be used. These medicines improve musculus strength by stamp downing the production of unnatural antibodies. They must be used with careful medical followup because they may do major side effects ( Nursing Link, 2013 ) . What is the forecast? With intervention, the mentality for most patients with MG is bright: they will hold important betterment of their musculus failing and they can anticipate to take normal or about normal lives. Some instances of MG may travel into remittal temporarily and muscle failing may vanish wholly so that medicines can be discontinued. Stable, durable complete remittals are the end of thymectomy. In a few instances, the terrible failing of MG may do a crisis which requires immediate exigency medical attention ( Nursing Link, 2013 ) . How is Myasthenia Gravis Diagnosed? The first stairss of naming MG include a reappraisal of the person ‘s medical history, and physical and neurological scrutinies. The marks a doctor must look for are impairment of oculus motions or musculus failing without any alterations in the person ‘s ability to experience things. If the physician suspects MG, several trials are available to corroborate the diagnosing. A particular blood trial can observe the presence of immune molecules or acetylcholine receptor antibodies. Most patients with MG have abnormally elevated degrees of these antibodies. However, antibodies may non be detected in patients with lone optic signifiers of the disease ( Nursing Link, 2013 ) . Another trial is called the edrophonium trial. This attack requires the endovenous disposal of edrophonium chloride or tensionA ® , a drug that blocks the debasement ( breakdown ) of acetylcholine and temporarily increases the degrees of acetylcholine at the neuromuscular junction. In people with MG affecting the oculus musculuss, edrophonium chloride will briefly alleviate failing. Other methods to corroborate the diagnosing include a version of nervus conductivity survey which trials for specific musculus â€Å" weariness † by insistent nervus stimulation. This trial records weakening musculus responses when the nervousnesss are repetitively stimulated. Insistent stimulation of a nervus during a nervus conductivity survey may show decreases of the musculus action potency due to impaired nerve-to-muscle transmittal ( Nursing Link, 2013 ) . The Future The hereafter of Myasthenia Gravis lies in the elucidation of the molecular immunology of the anti-acetylcholine receptor response with the end of developing a rational intervention for the unwellness that will bring around the abnormalcy in the immune system that consequences in the AChR immune response. To this terminal, six wide classs of theoretical intervention schemes need to be explored. First, those interventions which target the antigen specific B-cells ; Second, those interventions which target the antigen specific CD4+ T-cells ; Third, those interventions which interfere with co-stimulatory response for antigen presentation, Fourth, interventions aimed at bring oning tolerance or anergy of the CD4+ T-cell to the car antigen or the CD4+ epitopes ; Fifth, those interventions designed to excite those immunological circuits which activate CD8+ cells specific for the activation antigens expressed by CD4+ cells and Sixth, those interventions which intervene with cytokine map and discourage autoimmune mediated inflammatory responses ( Howard, 2010 ) .
