Chronic Wound Care Essays

Chronic Wound Care Essays Chronic Wound Care Essay Chronic Wound Care Essay The management and care of persons with severe or chronic wounds with their extensive effects have a challenge to both practitioner and patient. The challenging bit is the paucity of the treatment based on evidence strategies for the care of chronic wounds. After going through numerous databases, this paper will try to review chronic wound care and its management articles. Applying this available information, this literature review will be based on evidence concepts relating to the treatment of the chronic wounds while focusing on the basic principles for treatments. Chronic wound management According to Srensen (2012), a wound is a distraction of the normal functioning of the skin or skin structure. An acute wound damage caused by trauma inflicted on skin cells. This can be intentional as in cases where doctors conduct surgical procedures or by accidents such as blunt objects, chemicals, electricity or heat. The best approach to the study was through classification and treatment to wound care. In his findings he concluded that; An acute wound is expected to heal progressively through the normal wound healing stages and with time the wound will close up. Srensen (2012), further recommend that; It is important to recognize that, different causes of wound determines the length of time the skin would heal, the higher the level of trauma the longer the time the skin cells would take to have a quick recovery. Romanelli (2014), establishes that chronic wound in his study found out thata chronic wound; is one that fails to respond to normal treatment or does not progress as other normal wounds over the normal expected healing time frame (usually four weeks). Instead, the healing process stagnates at the inflammatory phase. Chronic wound care the essentials Chronicity of wounds can be attributed to a series of intrinsic and extrinsic factors which include poor nutrition and inappropriate dressing. Other factors such as diabetes also lead to chronicity of a wound, poor nutrition and improper dressing alone do not determine the wound healing process. Medical interventions such as a boost of the immunity should be able to reduce the chronicity of a wound. Dettmers, Brekelmans, Leijnen, Ritchie (2016)found out that there are numerous causative types of wounds; acute surgical wounds: during surgical procedures, a sharp object may be used to deliberately cut through the skin tissues. Acute wounds normally undergo a natural process of healing where the damaged tissues and cells will undergo restoration and body anatomy, and functioning will ultimately achieve their integrity. An acute wound that fails to heal within a period of 6 weeks might end up becoming a chronic wound. Acute wounds require proper dressing, it also needs the patient to watch over their nutrition at the time. Medical interventions alone is not enough to help absolve the problems of chronic wounds. Trauma wounds are as a result of a stressful event caused by mechanical or chemical injury that leads to damage of tissues. Trauma can have a serious short term and long term effects based on its level. It is important to treat each level of trauma with utmost care to avoid would chronicity. Chronic wound care management and research According Jeschke Rogers (2016)Burns are injuries sustained by skin tissues due to heat, electricity, friction or radiation. Heat causes rug burns while friction cause rope burns. Chemicals, on the other hand, cause caustic burns when one comes into contact with them. Chronic wounds usually fail to heal orderly and within the expected times. There are different environments for chronic and acute wounds. Some of the clinical signs of chronic wounds include lack of reduction of the size of the wound as time progresses, frequent and recurrent breakdown of the wound, and the granulation tissue is unhealthy. Burns should therefore be handled through the use of heat dissipation mechanism in order to reduce any inflammatory conditions. Pressure injuries according to Melbourne 2016,are injuries to the skin and the underlying tissues mostly on a bony surface as a result of friction or pressure, or a combination of both. Infected wounds: pathogenic microorganisms can invade wound tissues, causing additional damage to cells and tissues through secretion of toxic substances. It is valid to say that pressure injuries need more attention as they can turn to be inflammatory and swellings are a common part of it. Protection against festurization of the wound is important. Dickinson Gerecht (2016)study have generated sufficient evidence to show that a moist environment is ideal for the healing process of wounds. As a result of this, there has been a proliferation of wound dressings that have higher acquisition costs than standards dressings, leaving wound care providers in a state of confusion as to when be the appropriate time to use these relatively more expensive methods. Burn wounds, chronic wounds and pressure wounds require specialized dressing, other wounds such as sharp object wounds do not need any specialized care. Chronic wound treatment Ubbink et al. (2013) found thatadvanced wound dressing, using foam, for instance, has more control of the wound surface through the retention of moisture and absorption of exudates; in the process, the wound base and the surrounding tissues are protected. Maintenance of optimal moisture content ensures that the patient remains comfortable before, during and after the wound dressing process. The choice of which dressing to use will vary depending on the nature of wound base and the exudates. The selection of the dressing to be used therefore calls for training, experience and a level of expertise in wound care. Wound dressing using foam should be used in cases where a patient has experienced a high level of trauma on the skin such as a burned skin. This mechanism of dressing works best for wounds that are highly septic and require multiple change of dressing. Paul (2015)established that; the inflammatory phase takes up to three days from the point of infliction of injury. It is characterized by the bodys natural reaction to injury and is characterized by vasodilation that leads to increased blood flow that leads to swelling, pain and redness. At times wound ooze may be experienced which is a normal function of the body response. The proliferation phase takes between 3 to 24 days and is the phase when the wound is undergoing healing. The body generates new blood vessels and tissues that cover the wound surface. It is the reconstruction phase, and the wound will ultimately become smaller as the healing process progresses. The maturation phase takes between 24-365 days is the final phase of healing and is characterized by the formation of scar tissues. At this phase, the wound is still at risk and should be adequately protected. In many other cases, wound healing takes a shorter time that the projected 24 days, the level of trauma and chroni city of the wound can push the healing period past the 24 days mark. Inconclusion chronic wound care and management based on evidence should recommend the following healing mechanisms; Primary intention: this is where surgical wounds and recent traumatic injuries are dealt with by primary closure- the edges of the wound are secured by staples and minimal tissue loss and scarring occurs. Delayed primary intention is the surgical closure of a wound that is performed 3 to 5 days after a thorough cleaning of the wound bed has been done. Skin graft: this is the removal of a partial or full segment of the epidermis and the dermis, removing it from its blood supply source and transplanting it on another site to expedite the healing process and prevent infections. Skin grafts can be a perfect mechanism of hastening the healing process but it is important to be highly careful when selecting a skin graft section as a mismatch can create another wound due to poor match of the skin parts. A skin graft can be a perfect cure but it is a risky measure in wound heali ng process. References Dettmers, R., Brekelmans, W., Leijnen, M., Ritchie, E. (2016).

A QA Interview With Film and TV Critic Troy Patterson

A QA Interview With Film and TV Critic Troy Patterson Troy Patterson wears many hats, though hed hate that cliche. Hes a book critic for NP, TV critic at Slate.com and the film critic at Spin magazine. He also written for a host of other publications including The New York Times Book Review, Mens Vogue, Wired, and Entertainment Weekly. Patterson, who calls Brooklyn home, is a wickedly funny and nimble writer who crafts sentences like this one about Jon and Kate Gosselin, the feuding couple at the center of Jon Kate Plus 8: She is a moaning 34-year-old harpy with highlights as wide as mountain-bike tires sporting an asymmetrical haircut suggestive of a wounded stork. He is a sullen 32-year-old layabout whose skate-punk sideburns and gelled forelocks signal boring bad news. And, on the show, both struggle to act half their age. Or read his take on The X Factor: People like to talk about how reality TV attracts exhibitionists. This was literalized last night when a pervert at the Seattle audition dropped his pants, inspiring Paula Abdul to discreetly vomit. If we set him aside, the most memorable rejectees were the geriatric husband-and-wife team of Dan and Venita. They warbled off key through Unchained Melody, wore clothes too transfixingly tacky to rate as vintage, and were mildly lobotomized in manner. If this were a tryout for a dinner-theater adaptation of a David Lynch film, they would have definitely gotten a callback. Heres a QA with Patterson. Q: Tell me a little about your background: A: As a kid and teenager in Richmond, Virginia, I was a big reader Twain, Poe, Hemingway, Vonnegut, Salinger, Judy Blume, detective novels, out-of-town newspapers, Cheerios boxes, whatever. I got hooked on magazines by way of Tom Wolfe and Spy. I went to college at Princeton, where I majored in English Lit and edited the campus weekly. After graduating, I lived in Santa Cruz, California, for a little while, working in a coffee shop and freelancing for the local alt-weekly. Those were the clips I used when I applied for a magazines jobs in New York. I worked at Entertainment Weekly for seven years, where I started as an assistant and later became a book critic and staff writer, and I left EW on my 30th birthday to freelance and to fool around writing fiction. In 2006, I went to Slate, where Im on contract, and subsequently picked up regular gigs reviewing movies for Spin and books for NPR. Q: Where did you learn to write? A: I think that all writers educate themselves through practice, practice, practice. It helps to have good instructors along the way (mine include nursery-school teachers to Toni Morrison) and to hunker down with the usual guidebooks (Strunk White, William Zinsser, etc). Q: Whats a typical workday like for you? A: I dont have a typical workday. Sometimes I write all day, sometimes I write for 90 minutes. Sometimes its all reading and reporting and research. Some days Im running around watching movies or recording podcasts or schmoozing with editors. Then theres keeping up with the news, fending off publicists, replying to hate mail, and staring at the ceiling trying to come up with ideas. Q: What do you most like/dislike about what you do? A: May I quote Dorothy Parker? I hate writing; I love having written. Q: Is it hard being a freelancer? A: You betcha. And success, though dependent on hard work, is also contingent upon pure luck to a ridiculous degree. Q: Any advice to aspiring writers/critics? A: Forget it; go to law school. But if youve got too much passion to resist becoming an arts journalist, then try to learn something about a broad range of history and cultureShakespeare, horror flicks, fashion, philosophy, politics, everything. And dont worry about developing your voice; if you study your elders closely and try to write naturally, itll develop itself.

PERFORMANCE AND CULTURE Essay Example | Topics and Well Written Essays - 2500 words

PERFORMANCE AND CULTURE - Essay Example Brecht invented and introduced the use of alienation effects in the theatre and plays. He is among the pioneer artist to develop a form of drama that has been called epic theatre in which ideas and didactic lessons are supposed to be more important and attention catching as compared with the other features and elements of the play (Frederic, 1992). Bertolt Brecht used his invented technique in many plays to attain his aim to encouraging people to think about the end, lesson and message rather focusing upon the emotions and characters. The following essay aim to discuss the way Brecht changed the traditional style in which the plays were written and staged. In this regard, the essay describes the efforts of Brecht in innovating new technique and style for the theatre and its use in his dramas. It has been unveiled that in the beginning Brecht was not completely successful to practice the alienation technique for gaining the desired results however; as his work grew mature he proved th e significance of the technique in form of several successful epic plays (Frederic, 1992). Bertolt Brecht and modernist theatre – Alienation technique and epic plays Bertolt Brecht held the firm belief that the actors should always strive to produce alienation effects in the drama in order to discard the traditional style of persuading the audiences with their characters in the play. Rather putting the audience into a trance the actors should go into the trace their selves so that they can present natural and lively performance in front of the audience. He believes that the way of speaking and the movements of the artists must be convincing and effective enough that audience can feel the real message behind the play rather getting lost in the fabrication of dialogues delivery. His dramas are considered as most importance and original work pieces in the European drama and he has widely recognized as most influential and prominent European materialist writer of the 20th century (Weber, 1984). The theatre practice of the twentieth century was heavily influenced and developed from the contributions of Brecht to the theatrical production and dramaturgy. He spent several decades in experimenting and developing the theory and practice of his epic theatre and devoted lot of time and efforts to bring something new and useful in the process of play making. He was inspired from the ideas of early theorists Erwin Piscator and Vrevolod Mayerhold regarding the use of theatre for as platform for the propagation of the political ideas. He believes that drama and theatre are medium for the transmission of ideas and thoughts and the audience should not stop thinking when the drama ends but the drama should be meaningful enough that the audience could initiate the thinking process during and after watching the drama (Willett, 1977). Brecht wants to support re-functioning of theatre in to a social use rather becoming a source of entertainment. His concentrated efforts and research work around the topic have resulted in the evolution and popularity of Brechtian theories and techniques that were widely uses in the theatre and cinematic practice. In the early days of his career in theatre and play making Brecht was more interested in doing experiments with dada and expressionism. However, as he proceeds with his work he attained maturity and new ideas and within few years he succeeded to develop a unique style of

Argument Essay Example | Topics and Well Written Essays - 1250 words - 1

Argument - Essay Example Thus, the issue of awarding the capital punishment remains a highly controversial topic across the world. In the US many states award death penalty to offenders who commit premeditated homicide while some others do not have capital punishment. Killing a human being intentionally is a heinous crime and offenders who commit premeditated homicide need to be punished with capital punishment to deter others from engaging in such criminal activities. Criminal justice system awards punishment to the criminals with a view to prevent the recurrence of crimes. The society considers that every criminal offender needs to be awarded a punishment appropriate to the crime he or she commits. Thus, the advocates of death penalty contend that when capital punishment is awarded to a person who commits murder, â€Å"potential murderers will think twice before killing for fear of losing their own life† (The Death Penalty: Arguments for and Against the Death Penalty 1). Evidence also points to an a nalysis by the criminologist Isaac Ehrlich, which shows that â€Å"for every inmate who was executed, 7 lives were spared† as other perpetrators become deterred from committing similar crimes (1). This source concedes to the fact that studies relating to deterrence are sometimes â€Å"inconclusive† but it attributes this to the rare use of death penalty and the delay in its execution (1). Thus, it can be construed that death penalty acts as a deterrent to crime, which is a â€Å"practical justification† for the award of capital punishment (2). Criminal justice system relies on the basic tenet that every crime deserves a proportionate punishment for meeting the objectives of natural justice. Therefore, it appears natural that the person who perpetrates a premeditated murder of another person should be punished with death so that the victim and his or her family receive justice. Thus, the principle evolves that criminal justice must consider the extent of â€Å"h arm caused by the criminal† and award a punishment that is â€Å"proportionate† to the crime (Bidinotto 20). However, the opponents of capital punishment hold the view that punitive measures derive from the concept of vengeance and the â€Å"vindictive notion of an eye for an eye† (23). Refuting this theory, Bidinotto argues that justice does not rely on the notion of vengeance but, on the other hand, is â€Å"based on retribution† (23). He further contends that showing mercy to murderers amounts to â€Å"negation of simple justice† and will actually act as an encouragement for criminals as they can â€Å"gain more from crimes than any costs they will have to bear† (23). Thus, it becomes evident that a punishment proportionate to the crime is only moral and, therefore, the award of capital punishment to a murderer is justified. Deliberate murder is a crime that destabilizes the society and, therefore, when such crimes occur the community has a responsibility to respond. The death penalty can be considered as a â€Å"uniquely powerful† response to such a crime due to its being a â€Å"permanent† solution that cannot be â€Å"retracted or overturned† (Gelernter 26). Thus, by awarding death penalty to criminals who commit the offence of premeditated homicide, society makes a proclamation that such crimes are â€Å"absolutely evil and absolutely intolerable† (26). Therefore, it will dissuade criminals from engaging in such crimes and reduce murders. Though the opponents of death penalty are

Women, Work, and Family Foundation Essay -- Government Rights Feminism

Women, Work, and Family Foundation With the war in Iraq nearly two years old, I hoped that new leadership in the executive branch would put an end to the destruction overseas and funds would be redirected to rescue our receding economy, unemployment rate, healthcare services, and living conditions for the struggling American majority. November 2nd came and went, and those of us who shared my views found ourselves the minority. We shed a few tears and yelled at the unresponsive television screen, and surprisingly enough, the sun rose the next morning. No apocalyptic horses or trumpets, just a few chosen liberals feeling suddenly beckoned toward the promised land of Canada where certain rights are more a thing of the present rather than a dream of years to come. It is important to remember that while we do not make the decisions concerning the deployment of troops or the dropping of bombs, we do decide what condition we would like our country to be in when those serving the military are lucky enough to return home. In o ur current situation, I feel compelled to turn away from protesting the war and refocus on the home front. Many grassroots organizations have been inclined to take initiative in improving domestic policy while the president is not looking. For this reason, I have received another invitation to make a tax deductible donation to a non-profit organization: The Women, Work, and Family Foundation. I now have the personal opportunity to improve gender equality in the American workforce and receive a mug and free subscription to Newsweek in the process.

BMW Operations Management Essay

1. Executive Summary This report will describe a named organisation in terms of a general introduction and background of that organisation. For the organisation described, there will be a detailed account and critique of quality management and capacity management issues within the business. This will then be backed up with relevant academic theory and models; in addition to this there will be a description of their relevance in the business environment, citing examples of their use. The report will then finish with a conclusion and possible recommendations for the chosen organisation in regards to their operational management style and how it could be improved. 2. Introduction 2.1 Background BMW is primarily a German automobile company. It also has operations in aircraft engine production; electronic systems and hardware production; finance; and service. It had revenues of more than $27 billion and net profits of nearly $700 million in 1990, with about 65,000 employees. Bayerische Maschinen Werke GmbH as it is otherwise known was the surviving entity of a merger in 1955 between BMW and Allegemeina Flugzeug Werke (AFW). BMW has a history dating all the way back to the early 1920s when it was founded as a machine shop on the outskirts of Nuremberg. The AFW part of the company was founded in 1910 and was one of the major contributors of military aircraft during the First World War. The automobile industry can be very volatile and mistakes in decision making can prove to e extremely costly. BMW has proved over time that through careful management the number of errors a firm makes can be greatly reduced. BMW’s operations management is also of a high standard; it designed a production system where new parts can be produced in small amounts and only result in a moderate cost. 2.2 Methodology Research will have to be done in developing the report before any reflection can be made on its contents. There are a number of sources available to get the relevant information from; a many number of books are accessible that go into great detail on each subject within operations management. These will provide a range of academic theory and models which can then be applied into business terms. The internet also provides a vast amount of information that can be used as a reference in the writing of the report, it not only refers to academic theory but also other authors reflections on certain topics which can then be used to draw ideas and apply them to the report. 2.3 Structure of the Report This report will describe a named organisation in terms of a general introduction and background of that organisation. For the organisation described, there will be a detailed account and critique of quality management and capacity management issues within the business. This will then be backed up with relevant academic theory and models; in addition to this there will be a description of their relevance in the business environment, citing examples of their use. The report will then finish with a conclusion and possible recommendations for the chosen organisation in regards to their operational management style and how it could be improved. 3. Findings The operations management task is defined as the day-to-day production of goods that continually requires decisions to be made and the implementation of changes. Operations Management is different to that of other management topics such as strategy, marketing or finance. Whereas these fields are based on theory such as economic, social, and mathematical factors; Operations Management is much more difficult to pin down to a specific aspect. It takes into account a vast array of academic and practical applications that when communally put together produce a basis from which decisions can be made. Operation managers that work inside an organisation work on the foundation of balancing the quality of the service that they provide against the resources they currently have available to them. They are required to be highly skilled in managing their current capacity output so that it can cope with the ever changing levels of demand placed upon their organisation. There are many ways that managers cope with the levels of demand; a manufacturing manager such as BMW would attempt to influence the demand through an assortment of different marketing techniques. In any organisation there will be a relationship between their capacity management, quality management, and their resource productivity. There are a number of issues that arise when trying to manage the organisations supply and demand. Managers must keep to their productivity targets without adversely affecting the quality of the product that they produce; striking a balance can prove difficult especially in the automobile industry where mistakes can prove to be very costly. 3.1 Capacity Management Capacity management is finding the balance between the demand from customers and the capability of the organisation in satisfying that demand. There is a great need for managers to forecast what they think the demand might be in the future so they can sufficiently change their capacity to cope with the change. Where the capacity of the organisation is limited the focus will be on influencing the demand to be in line with the available capacity, this is referred to as level strategy. The opposite of this is chase strategy; this is where the supply can be changed to meet the fluctuating level of demand. Managers can direct their operational control by altering the capacity of the organisation, hold items in inventory in case of a sudden increase in demand, oblige customers to wait for their product, or attempt to influence the demand themselves. In the automobile industry it is possible for an organisation to produce cars in advance of demand and hold it in inventory. Operations managers must at all times be wary of their current capacity, to what degree it can be changed, the costs involved in changing that capacity, and the speed in which the change can happen. This is most important in organisations where profitability is linked to that of capacity and the prices charged for their product or service. BMW is already a leader in the niche car segment of the automobile industry. To retain that status BMW built a $660 million Research & development centre and plans to invest more than $1 billion each year in finding new ways to exploit their position as a market leader. BMW are aware of the fact that they are not one of the biggest companies in the industry and can’t mimic the bigger companies who have far greater capacity and financial power. BMW try to innovate new ways to stay ahead of their competitors. They designed a new manufacturing plant where the cars would move down the assembly line on an independently powered gantry. The new technology would produce sound waves so that collisions can be avoided, thus reducing the need for more workers and also reducing the risk of unwanted accidents in the plant. The output achieved by any capacity management system depends on a number of factors that relate the resources currently available to the actual output of the organisation. It is sometimes inevitable in the niche car segment that an organisation will run out of capacity to cope with the ever changing levels of demand. If this problem occurs then the management can carry out two possible courses of action: o Allow the quality of the product to decline o Attempt to influence the demand so it doesn’t affect the organisation in the long term. In the scenario where the capacity of the organisation is in excess of the demand, this can lead to lower efficiency and a lower quality service to the customer. 3.2 Quality Management BMW believe that quality is of key importance in every stage of the manufacturing process, from product conception to customer feedback. They base their working principles around consistency and complete coverage of all requirements throughout the development and production process. Quality control within BMW is achieved through a system of quality audits at every stage of the manufacturing process; the productions of parts, components and in the assembly plant are all thoroughly maintained. These same quality control principles also apply to their suppliers of materials and components, with all of BMW suppliers agreeing to work to specific specifications of quality. Once cars arrive in the distribution centre, they take on a quality check and have a full pre-delivery inspection before being delivered to the customer. Quality driven organisations are more likely to integrate human resource management into their strategy as employee participation can be seen as key to bolster quality. The BMW management structure allows for teams, comprising of employees from all levels, to react quickly if a fault is found and work together immediately on a problem if one should occur. BMW also benefits from excellent personnel management that allows them to motivate their employees and create a friendly working environment. It provides its workers with a highly competitive pay package and supplies special contracts that allow certain workers to work four-day weeks. Every member of staff is fully responsible for the quality of their work and this well help lead to job enrichment for every member of the workforce. The company has never lost its focus or attempted to spread itself across the entire automobile industry. This is an example of quality management because if the management had been slack, BMW would have lost its focus and attempted to make products for everything and everyone. Manufacturing firms, such as BMW, are always searching for new and innovative ways to cope with global competition in the ever changing business environment. One such process that has been implemented at BMW is that of a focused factory. The complexity that comes with an automobile manufacturer can provide a barrier to managing these facilities, thus the creation of a focused factory solves this problem. The focused factory is a â€Å"plant established to focus the entire manufacturing system on a limited, concise, manageable set of products, technologies, volumes, and markets precisely defined by the company’s strategy, its technology, and its economics.†( APICS Dictionary 1992). Manufacturing companies implement this technique to improve the organisations productivity, quality, and responsiveness. BMW can focus their equipment, employees, and technology one specific tasks rather than using the same technique for all of their different projects. Implementing focused factories make it easier to manage production systems, reduce inventories, and reduce manufacturing space and investment requirements. As BMW have a strong quality emphasis with more attention being given to the performance of the organisation, the use of appraisals is crucial to the requirements that lead to producing a quality product. They place customers at the centre of attention as it is in any organisation that takes quality so seriously. The appraisal process necessitates the employees to evaluate each of their peers so that it encourages them to produce quality work and so to satisfy their customer-supplier relationship. 4. Conclusion Successful automobile manufacturers in the future will need to maximise efficiency, eliminate waste, adapt to change and implement strategies that stay in line with their customer requirements. BMW will need to keep modernising their internal operations to keep up with the constant changing in the automobile industry. Streamlining their plants will facilitate the balance between supply and demand while keeping the quality of their product high. Decisions within BMW are now made throughout the organisation, from the factory floor up to the chief executives. This has increased the communication between all levels of the organisation making it more flat and thus increasing the quality of the automobiles. Jobs have become more diversified with the need for new knowledge and skills becoming more crucial, as the global competition increases, more needs are placed on the company to provide products that meet consumer desires. The main link between the customer and organisation has always been the shop floor assistant. Performance feedback, audit results, and customer opinion surveys are the ways in which organisations know if they are doing there job to satisfactory standard. BMW make sure that the assembly workers are aware of the consumers’ requirements by providing suitable training and sound environment so that those requirements can be met. Organisations that cut down on investment in employee development will suffer a decrease in employee performance due to the close relationship between the two, and this will ultimately filter down to the consumers. Operations management in relation to automobile manufacture is crucial in defining priorities and identifying possible problems. One possible problem that might be confronted in the near future is that of overcapacity in terms of passenger cars. It is seen that other cars such as sport-utility vehicles don’t suffer from overcapacity as they are usually custom made to the consumers’ preferences. Passenger cars are normally batch produced on a production line in their thousands and organisations have a wealth of stock kept in their inventory. Automakers usually add capacity in the 100,000s so the market is never satisfied precisely; there is either a demand lag or a saturation of the market. Costs remain vitally important in making strategic product-line decisions. Regardless of the preferred quality or productivity quota, BMW must stay concerned with the continuous improvement of the business by improving quality, productivity, customer service, and delivery. 5.

What Is a Polygraph Test A polygraph machine is used to attempt to detect physiological changes that are thought to occur when a person tells a lie. These measures include the blood pressure, the amount of sweating on the palms and the heart rate. Polygraph testing is currently being used to investigate crime in a number of countries around the world,including the USA, Japan, South Korea and Israel (Raskin, 1990). Don’t waste time! Our writers will create an original "Example Psychology Essay" essay for you Create order At present there is a wide-ranging literature evaluating the use of the polygraph machine and associated techniques, largely based on laboratory experimentation.Like any psychometric test, the use of a polygraph machine in the detection of deception has been questioned on the basis of its reliability and its validity. Reliability refers to the ability of a test to be consistent, no matter who is carrying it out. The question of validity asks whether the test is actually measuring what it claims to measure. The answer to both of these questions is vital in answering whether the polygraph should be introduced into British policing. The polygraph machine has been used in a number of different ways to elicit useful information from suspects. Bull, Gudjonsson, Hampson, Baron, Rippon, Vrij (2004) identify four main techniques: the Relevant/Irrelevant Technique, the Directed Lie Test, the Control Question Test, and the Guilty Knowledge Test. Of these, the majority of research has addresse d the last two and so the discussion will concentrate on these. The Control Question Test The theory behind the Control Question Test (CQT) is that the physiological responses of a suspect to control questions are compared with those which are directly relevant to the crime. Control questions are specifically chosen to be vague in nature and to relate only indirectly to the crime under investigation (Iacono Patrick, 1997). This means that they should provoke high levels of physiological arousal in innocent suspects as they are designed to elicit guilty memories but those that are not under investigation. By contrast, to an innocent interviewee, the specific questions about the crime should evoke lower physiological arousal as they can be categorically denied. To the guilty interviewee, however, the reverse pattern should be seen with higher physiological response seen to the more specific questions. The basic paradigm for assessing the polygraph test used in laboratory investigations involves a mock crime with participants randomly told to act either innoce nt or guilty. Raskin (1982), for example, explains that the guilty participants enact the mock crime, while the innocent participants simply have the facts relayed to them. Both groups are given a cash incentive to pass the test, and this goes some way towards giving them the required motivation to pass the test. Many of the earlier studies used the CQT test and found some encouraging results. Carroll (1988) summarises some of these studies, referring first to the Office of Technology Assessment of the United States Congress (1983) which rounded up 14 studies which found an overall accuracy level of 88.6% in the guilty participants, and 82.6 in the innocent participants. However, Carroll (1988) criticises this assessment as some of these studies had flawed methodologies. Instead, using stricter criteria, the figures of 85.4% for guilty and 76.9% for the innocent were found. Carroll (1988) makes two important points about most of these studies. Firstly, there was a fairly high rate of false positives of around 20-25% instances where the participant was innocent but pronounced guilty. Secondly, the polygraph operators also have their own visual information to go on when carrying out the test, they are not simply relying on the physiological data. This means that the results cannot be fully attributable to the polygraph as the human operator could be partly acting as a lie detector. The most obvious criticism of these kind of studies is that of ecological validity. The test itself relies on the emotional reactions of the participants how likely is it that monetary inducements are equivalent in motivational terms to the chance of being convicted of a crime? For this reason, MacLaren (2001) points out that the participants have little reason to be worried about the important questions and are unmotivated to try and beat the test unlike a real guilty suspect. Field studies, then, have attempted to fill this gap, but immediately the problem aris es of how it is possible to measure whether a person is really guilty or innocent. In reviewing the data on field studies, Carroll (1988) found that generally the accuracy rates were low at 69.6% comparing to the 50% obtainable by chance this does not seem high. In addition, there was a very high rate of false positives 43%. More recent field studies have been reviewed by Bull et al. (2004), who find better average figures for those guilty suspects at between 80% and 90% accuracy, but still poor results for innocent suspects, with false positives ranging from 12% to 47% accuracy. The theoretical problems with the CQT have been pointed out by Ben-Shakhar (2002), amongst others. The whole design of the test is such that the operator of the polygraph is trying to deceive the suspect something that may be perceived as unethical. It is still possible to imagine good reasons for why an innocent suspect would show arousal to the specific questions these are still anxiety pr ovoking questions. There is little evidence that this test is standardised, in that the control questions that are asked in each interview are different. This means that much variability in the accuracy of test is probably due to the operator this reduces the theoretical reliability of the test. The Guilty Knowledge Test False positives, then, are one of the major problems with the CQT. The Guilty Knowledge Test (GKT) has been shown to meet this challenge. The GKT is designed to try and uncover whether the interviewee is withholding information about a crime under investigation. This involves asking the suspect a number of specific questions about the crime, each question having a number of alternatives, only one of which is correct. The operator then looks for a pattern of physiological responses to the correct option across the whole test. This test is much more difficult to apply, mainly because it requires the test operator to know a number of facts about the crime that she must be reasonably sure that the guilty suspect would also know these would tend to be details, although does not exclude major facts. A range of reviews have been carried out on the GKT in laboratory conditions. Ben-Shakhar and Furedy (1990) found accuracy rates of 84% for guilty participants and 94% for innocen t participants. Elaad (1998) found rates of 81% for guilty and 96% for innocent. While these are encouraging, again it is the field studies that are more convincing because of ecological validity. Only two of these have been carried out. Elaad (1990) found rates of only 42% for guilty participants but 98% for the innocent. Similarly Elaad, Ginton Jungman (1992) found 76% for guilty and 94% for innocent. Ben-Shakhar, Bar-Hillel, Kremnitzer, (2002) defend the low results for guilty suspects, claiming that they were carried out under sub-optimal conditions, being just after a CQT had been carried out and only involving an average of 1.8 questions. Overall though, levels of false positives are much lower for the GKT than the CQT. Perhaps the biggest criticism of the GKT relates to how useful it is in a practical sense. The nature of the test requires that the interviewer has been able to amass half a dozen items of knowledge that the guilty person would be aware of that wou ld not be recognised by an innocent person. In addition, it is not always possible to be confident that the suspect will have remembered or even noticed the particular details which the operator refers to. Bull et al. (2004) makes the point that, in high profile cases, details are often released to the public to aid the solving of the crime, which will make the interviewing of the suspect even harder using a GKT, as innocent suspects will know many more details of the crime, making the choice of details for interview more obscure. The advantage of the GKT is that in evaluating its theoretical underpinnings, some researchers have made much stronger claims for it than the CQT (The Committee to Review the Scientific Evidence on the Polygraph, National Research Council, 2003). The reason for this is that the GKT relies on the response being greater to a particular subset of the questions relative to whatever the physiological response is to the other questions (Carmel, Dayan, N aveh, Raveh Ben-Shakhar, 2003). This is unlike the CQT where variations in the physiological response of the suspect will tend to disrupt the test. In addition, the GKT does not rely on duping the suspect. The GKT does also have practical advantages. Ben-Shakhar et al. (2002) point out that a problem for the admissibility of polygraph tests in court is that they can become contaminated. In practice, a polygraph operator has the evidence of his eyes as well as the polygraph machine to go on. This may mean that the operator does not entirely base his decision on the physiological data. The advantage of the GKT is that it is much more easy to carry out blind, or for another polygraph tester to simply look at the physiological evidence. Counter measures and Base Rates Two other criticisms that apply more generally to all the different types of polygraph tests, are the effects of countermeasures and of base rates. Countermeasures refers to attempts to beat the polygraph test, these Gudjonsson (1988) classifies in three ways: reducing reactivity, suppressing physiological reactions and augmenting physiological reactions. According to Ford (1995) a man named Floyd Fay was able to successfully train 23 of 27 fellow inmates to beat the polygraph test in 20 minutes despite their admission of guilt to crimes for which they had been incarcerated. On the problem of base rates, Bull et al. (2004) point out that the kinds of situations in which polygraph tests are used may mean that there are a large number of suspects to test. This will exacerbate the problems of false positives, although, perhaps, is not such a problem in forensic situations as numbers are more likely to be limited.
