UWB Ad-Hoc Networks Essay Example | Topics and Well Written Essays - 10000 words

UWB Ad-Hoc Networks - Essay Example gnal has a bandwidth that exceeds the lesser of 500 MHz or 20% of the center frequency, there is an authorized unlicensed use of the frequency range starting from 3.1 GHz and up to 10.6GHz, also the emission limit is -41.3 dBm/MHz. This technology uses the Impulse Ratio (IR) method for its transmission; the rate is different for radar and imaging purposes to the communication purposes. The rate of impulses for radar and imaging is in the range of 1 to 100 mega pulses per second. The communication rate can be in a range of 1 to 2 giga pulses per second. This diagram shows how much faster Ultra Wide Band technology is over any existing current technologies also it provides a high level of mobility which is important for a mobile devices it is intended for. The advantage of UWB over traditional radio transmissions is that traditional way would be to modulate the frequency and phase of the signal as well as power, of a sinusoidal wave. However UWB transmits impulse at a specific time, there fore it allows pulse position modulation and time modulation. Among the advantages of UWB that helps to prevent multi path propagation. It gives the possibility of the system to establish the time for an impulse to travel from the transmitter to the receiver in the direct path. The other advantage of UWB IR system is the short length of pulses does not allow them to overlap so the multipath fading is not an issue in this case. On the other hand in a system with high pulse rate there can be inter-path interference, it can be eliminated by error correction coding at the receiver. UWB can be combined with multiple antenna technology that doesn’t only allow increase in transmission speed but increases the reliability of the channel, there are a number of solutions that can increase the transmission speed over the regular SISO (single-input single-output); Technologies like multiple-input and multiple-output (MIMO) allows reaching gigabits per second range of transmission speed.

Assignment on Eastern and Western Europe Example | Topics and Well Written Essays - 1250 words

On Eastern and Western Europe - Assignment Example Due to the second World War, the so called Iron Curtain was established in Eastern and Central Europe. During this time, the Soviet Union established a strong program of influence on many of these Eastern Bloc countries, making them so called satellite states, under complete control of the Soviet Union, sometimes through its support of autocratic dictators. This reflected the historical problems of approaching true communism from an Eastern Bloc perspective, as a direct result of the growing tensions between the USA and USSR in post-World War II Berlin. After the closing off of Berlin and the separation of an entire city by the infamous Berlin Wall, the stage was set for the metaphor of the literal division of Europe. In the west, there was a lot of cultural and hegemonic influence from societies based on the concept of approaching socialism in some cases, but not true communism, and in many cases, very strong capitalism. In the east, there was the dominance of the Soviet power, whic h then aligned with local power in the creation of Eastern and Central European puppet regimes. #2 Central European countries that were more â€Å"Western† in their focus included Hungary and Poland. â€Å"Eastern† countries included the Baltic states and more northern areas. Poland seems to the lay person to be more similar to Germany than to Russia. The Czech Republic seems closer to Germany as well, considering the amount of German spoken there. Hungary seems more Russian, as do the Baltics. Of course, there are objective and subjective considerations to keep in mind, when it comes to ascribing national characteristics, or characteristics that are seen or said to be based on nationality. In any case, the cultural influence of other states and cultures can be divided between western and eastern ideas, in terms of political structure, and if the east is considered to be

UK NHS Framework for Coronary Heart Disease | Analysis

UK NHS Framework for Coronary Heart Disease | Analysis A Critical Analysis of the Impact of a Current Healthcare Policy on a Group of Clients/Users Introduction In considering the impact of a current healthcare policy on a group of clients/users, the United Kingdom’s National Service Framework (NSF) for Coronary Heart Disease (CHD), offers a classical example for examination of the foregoing. In particular women as a subject group provides an interesting basis by which to analyze user experience, quality of service as well as fairness/justice. Globally, 10 million of the 27 million deaths of women are as a result of Coronary Heart Disease with one third of the foregoing total, 10 million, occurring in developed countries (Bonita, 2000). And while Coronary Heart Disease is known to be a leading cause of death among men, it is also ‘the’ leading cause of death for European women (Mcguire, 2000). In the United Kingdom Coronary Heart Disease is the number one cause of premature death among both men and women and shows a marked skew with regard to social classification. The death rate attributed to Coronary Heart Disease among males from manual worker classifications is forty percent (40%) higher than for those from non-manual segments (National Health Service, 2005). And while coronary heart disease is four to five times more prevalent in males than females for the age groups under 65, the gap narrows considerably after this age. And this particular age occurrence discrepancy is one of the critical sources of misunderstanding, focus, appropriation, resources and service as the medical profession, insurance industry, and public in general tend to view coronary heart disease as primarily affecting males. And while the preceding is true, in terms of the age groups under 65 (Mcguire, 2000), the fact is that women live longer than men thus as the incidence of coronary heart disease and the associated care is spread out over a longer period as well as at a more advanced age. The circumstantial inequities that the preceding give or gave rise to shall be the examination points addressed herein in terms of considerations with respect to the impact of current health care policy in terms of analyzing user experience, quality of service as well as fairness/justice, with particular emphasis on women. In order to accomplish this broad and sweeping analysis, an understanding of the disease, and allied points will need to be established to provide the foundation from which to reach a determination as to the three subject areas indicated. Coronary Heart Disease A distressing fact that has been uncovered as a result of a study by the World Health Organization (1997) is that coronary heart disease is rising in developed countries. The World Health Organization (1997) attributed the foregoing to the increased overall age of relative populations as well as the onset of increasingly poor health behavioral patterns. Dr. Abby King (2000) indicated that of the forty plus studies that have been undertaken on a global basis concerning various aspects of coronary heart disease it was found that there was a correlation between physical activity and premature mortality. Dr. King (2000) stated that said study consisted of a field that was comprised thirty-three percent (33%) of woman. Said studies have shown that inactivity in women revealed on average a two-fold risk or the development of cardiovascular problems as compared to their peers who were or are more active. It was also uncovered through these studies that the economic costs in terms of not onl y the direct treatment but also, those associated with the relative inactivity of patients amounted to substantial outlays. The increase in coronary heart disease has also been attributed to the elevated cholesterol levels that are prevalent in Western countries. Dr. Anita Schmeiser-Rieder (2000) has found that approximately forty percent (40%) of women above the age of fifty-five (55) have serum cholesterol levels that are elevated. Dr. Schmeiser-Rieder (2000) indicated that the preceding condition peaked in women between the ages of sixty-five (65) and seventy-four (74) and that fully sixty-one percent (61%) of those researched had hypercholesterlomia. The disturbing finding that was uncovered in studies by the World Health Organization (1997) is that coronary heart disease and stroke will continue to be the leading cause of death among both men and women over the next twenty years, increasing to the second and third causes of death from its present ranking of fifth and sixth by 2020. The World Health Organization (1997) cites that the major causes of both stroke and coronary heart disease are: smoking high blood pressure cholesterol body mass index And while studies conducted by the WHO (World Health Organization) MONICA (2000) Project shows a decline in smoking trends, a rise in smoking among young woman as well as adult women has been noted in: Russia (Novosirbirsk) Germany (Augsberg) Belgium Spain (Catalonia), and Poland, where the recorded increase has been as much as ten percent (10%). As the number one cause of stroke and coronary heart disease, the rise in female smoking is alarming, made even more dramatic by the fact that females historically smoke less than their male counterparts across all age groups. The findings of varied studies has conclusively indicated that the incidence of stroke and coronary heart disease increases with respect to those individuals whose lifestyles expose them to the additional risks that are associated with the two conditions. The World Health Organization (1997) has determined that changes in lifestyle as well as personal habits effectively reduce the risk associated with contracting these diseases. The foregoing is of particular significance to women, as the emphasis on efforts to change lifestyles and habits has been primarily focused upon the male segment of the population whose rate of incidence with respect to stroke and coronary heart disease has been higher. The corresponding increase in poor lifestyle and smoking habits among females in the countries indicated reveals that such an approach has not only been short sighted, by failed to take into account the longer life cycle of females thus increasing the onset of coronary heart disease and stroke in later years as a result of higher age where female incidents almost match those of males. The foregoing factors are important base line informational points to develop an understanding of the varied inputs and considerations that comprise the complex variables inherent in equating the range of aspects to be addressed in analyzing user experience, quality of service as well as fairness/justice. The preceding points out the need to utilize what is termed as a ‘high reach’ strategy (Bonita, 2000) that reaches both the male and female segments of the population in terms of alerting them to the relative risks, preventive measures, lifestyle augmentation, and allied aspects known to have demonstrated a decrease in stroke and coronary heart disease when utilized in a proper manner. Such an initiative when conducted on a population-wide (high reach) basis helps to alert individuals to the relative dangers and causes of high blood pressure, negative connotations associated with smoking and lack of physical activity, the three highest contributors to the condition. Alerting populations to reduce the intake of salt, alcohol, saturated fat as well as the benefits of increased physical activity would reduce the relative levels of blood pressure and thus the corresponding reduction in medical costs assumed not only by individuals, but society at large. By combining the aforementioned with what is termed a high-risk strategy (Bonita, 2000), in efforts that are directed at the identification of women in this category, along with offering treatment to the women within this group whose risk factor(s) are above the norm in terms of the potential for a coronary disease event can generate significant improvements in long term results. The utilization of educational media efforts in combination with treatment availability is a preventive measure that recognizes the need to head off the high costs of medical facilities, and allied costs to the government via preventive measures. As the subject country being utilized for this examination is the United Kingdom, the foregoing is applicable. The same holds true for countries where insurance coverage’s are used to supplement individual treatment costs, along with the calculated losses to society with respect to the associated costs that accompany coronary heart disease events. In the case of the United Kingdom, with the taxpayers bearing the cost of medical care under the country’s socialized medical program, the realities of the treatment and after care costs of coronary heart disease are a real expenditure concern. In particular the recognition of the heretofore hidden costs in this area as a result of the scant attention paid to the real costs associated with women, the foregoing represents an opportunity to make an significant impact in cost controls, and more importantly the health of an entire segment of the population. And while women as a group have an overall lower absolute risk factor than men, in terms of the potential for women to have a coronary heart disease event, this differs depending upon the age group category. As indicated by Dr. Anita Schmeiser-Rieder (2000), forty percent (40%) of females who are above the age of fifty-five (55) years of age have elevated cholesterol levels and this condition actually peaked for the age group between sixty-five (65) through seventy-four (74) where sixty-one percent (61%) if the research group had this condition. The aforementioned supports the view that strategies aimed at high-reach in conjunction with high-risk represent a necessary approach to bring the incident of the risk of conditions that contribute to increased onset of coronary heart disease under preventive type control program measures. The preceding analysis takes on additional importance when one considers that estimates regarding the probability factors concerning woman above the age of fifty, as well as the increased incidence of smoking in young women and the need for education regarding lifestyle and health preventive measures to reduce probabilities later in life represent contributory factors that can be somewhat controlled. Prevention approaches to call attention to the risks of smoking, high cholesterol diets, and the lack of proper exercise represent measures that have shown to produce a reduction in coronary heart disease numbers over specified periods. Classified as lifestyle and personal habit changes, the reduction or elimination of known contributors that increase the potential of CHD (Coronary Heart Disease) has yielded positive results. It is important to note that in the instance of women, the absolute risk of coronary heart disease remains at relatively low levels until they reach their seventies and eighties, however, the reduction in conditions attributable to said condition in earlier years has been shown as a positive preventive measure (Bonita, 2000). As pointed out by Dr. Bonita (2000) the primary contributors to the coronary heart disease epidemic are: the onset of population aging, rapid urbanization, changes in nutrition, and smoking patterns, along with reduced physical activity Any program that purports to achieve relative success will need to incorporate the preceding along with post CHD treatment and follow up measures as well. Cardiac Rehabilitation Services The United Kingdom’s National Service Framework for coronary heart disease is under a revision program which the Secretary of State for Health, Alan Milburn, states the primary focus is the â€Å"saving of lives† by the reduction of â€Å"†¦the death rate from heart disease and †¦ stroke †¦Ã¢â‚¬  by â€Å"†¦ two fifths†¦Ã¢â‚¬  for individuals under the age of seventy-five (75) by the year 2010 (National Health Service, 2005). The preceding will be accomplished through the following measures (National Health Service, 2005): the development of a new vision concerning coronary heart disease, the establishment of a government-wide agenda, further development and improvement of the National Service Framework for CHD providing effective services to all individuals in the United Kingdom that can benefit The preceding directly address the three points user experience, quality of service as well as fairness/justice, along with other concerns. Through the modernization of the National Health Service’s treatment, care and public awareness approaches the objective is to improve the foregoing across age, gender, cultural, race, disability, locale, and religious lines, as well as being â€Å"†¦ responsive†¦Ã¢â‚¬  to the needs of individuals (National Health Service, 2005). Some examples of the need to revise and modernize the system is evidenced by the following facts (National Health Service, 2005): The wives of workers in the manual class are at twice the risk factor in developing coronary heart disease and stroke than the wives of workers whose jobs are of a non-manual classification. The morbidity rate among the manual class group is also higher than in the non-manual group designation, and this group also reflects increased incidences of angina, heart attack and stroke. The disparity in come between poor and rich has widened over the previous twenty years creating a further gap in health survivability as the more affluent segment of society has been able to afford private medical care as well as increased nutritional guidance and lifestyles that promote as well as can afford more physical activity. Historical records have shown that death rates are higher in the northern locales of the United Kingdom, representing almost three times the rate for individuals over the age of sixty-five (65) in cities such as Manchester than for Richmond or Kingston. The preceding further illustrates the inequities in terms of user experience, quality of service as well as fairness/justice. The new National Health Service program sets forth that it seeks significant improvement in the following areas, all of which will enhance the indicated three examination points (National Health Service, 2005): Standards The National Health Service is aiming to establish a ‘standard of care’ that includes an invitation for individuals whom have been admitted to a hospital for coronary heart disease to participate in programs consisting of cardiac rehabilitation and secondary prevention. The preceding is aimed at reducing future risk of cardiac problems and to help them to return to a normal life. Rationale Admission to a hospital represents individuals whose condition is severe. This signals that their lifestyles to this point have consisted of various high-risk exposures, such as smoking, high cholesterol diets, and other conditions that if changed can lead to significant improvements in rehabilitation. To accomplish the preceding said patients must be analyzed and then coached concerning the lifestyle changes and modifications needed to aid them in returning to a healthier manner of living to reduce future incidents and effect recovery. The World Health Organization (1997) defines cardiac rehabilitation as consisting of a â€Å"†¦ sum of activities†¦Ã¢â‚¬â„¢ that are necessary to effectively influence and identify the underlying causes of the disease to individuals through their own actions can help to effect their recovery. Through increasing the quality of service that offers comprehensive assistance that is custom tailored to their individual circumstances. The aforementioned provides the foundation to enable counseling and aiding individuals in understanding ways in which to change their lifestyle habits, as well as better understand their illness and effect the transition back to as normal and full a life as possible. The aim is to make rehabilitation â€Å"†¦ an integral†¦Ã¢â‚¬  aspect of the active as well as secondary preventive care regime. By establishing rehabilitative procedures immediately after discharge and the establishment of a long term formal program that focuses on returnin g the individual to the best health possible the government estimates a net gain of approximately  £15,700 per instance over a three year period. In the case of women, they represent one third of the individuals with coronary heart disease, yet just fifteen percent (15%) of their total utilize rehabilitative services (Green, 2000). The attention to improving the quality of service the initiative also aims at removing the disproportionate care provided that does not adequately cover rural parts of the country. Effective Interventions Participation barriers can be a result of varied causes, such as the lack of proper motivation to difficulties in attending rehabilitative sessions. In the case of women it was discovered that there was a lack of appropriate provisions, which the current modernization program seeks to correct to provide fairness as well as justice throughout the system. The foregoing also includes minority groups as well. In terms of improving the quality of service the new program consists of Four Phases (National Health Service, 2005): Phase 1 This Phase comes into effect before the discharge of an individual from the hospital, and is to be offered as a part of the acute care plan. It includes the following elements: review and assessment of psychological, physical and social needs for rehabilitation development of a written plan to meet identified needs counseling and advice on detrimental lifestyle aspects such as smoking, cholesterol, exercise, alcohol, etc. prescribing of medication and education on its proper use information concerning cardiac support groups Phase 2 As part of the early post discharge period individuals will receive the following: a comprehensive assessment of their cardiac risk which will include their psychological, social and physical needs for rehabilitation and the plan to achieve these ends lifestyle advice from trained therapists resuscitation training for members of the affected individual’s family Phase 3 This segment of the four phase plan comes into utilization four weeks after the cardiac events initial phase and consists of a series of structured exercise sessions along with ongoing access to support and advice from people trained to provide them with psychological interventions, promotion of health, exercise and associated advice. Phase 4 The final aspect of the four-tiered program that consists of: long term primary care follow up local cardiac support group involvement referrals to identified support services as initiated in Phase 1 The modernized and revised National Service Framework is a highly structured series of interlocking programs that are designed to alleviate as well as eliminate the missing components of the prior coronary heart disease plan which evolved over decades, into a comprehensive system that has been revised based upon today’s understandings. It aims to achieve coverage of all groups and categories of individuals through education, assessment, contact and a cardiac event that provides qualified, balanced and comprehensive coverage and care whose major components are as follows (National Health Service, 2005): The identification of individuals that are likely to benefit from a structured cardiac rehabilitation program before discharge from a hospital, the assessment of individual risks as well as needs, along with the development of a structured plan to achieve successful cardiac rehabilitation, the documentation and provision to deliver the proper treatment as well as advice the integration of required and agreed upon care that is weaved into the patients local network of primary and secondary treatment, preventive and related care, The experiences gained under the prior system, as well as all of the inequities have been addressed under the National Health Service’s new modernization plan that provides and sets relevant standards with effective interventions under structured service models that define and addresses the immediate priorities of each individual patient. Conclusion The scope and complexity that comprises the field of coronary heart disease makes this a subject whereby the factors inherent in its causes as well as manifestations entail equating aspects of human behavior across the entire spectrum of demographic, cultural, social and psychological realms to codify commonalities and possible associative elements that tend to explain the reasons and causes for the world’s most pervasive killer. As the field of examination represents healthcare, the core of understanding evolves an evolutionary process based upon decades of exposure, analysis and experience gained within the United Kingdom as well as on the world stage. The National Health Service has recognized the significance of the preceding and has crafted a program that seeks to build upon the known(s) within the subject field in a program that is flexible enough to improve upon itself to incorporate those aspects, considerations and new understandings that will inevitably will occur wi th new discoveries and as a result of the comprehensive data based system that will permit further modification and evolution. Thus, user experience, along with quality of service, and fairness/justice with respect to the new National Service Framework has been addressed to exclude the existing inequities and shortcomings, yet understands that it is an evolutionary process that will continue to modify and improve upon itself using past experiences along with the new framework as the foundation from which to accomplish this. The Secretary of State for Health, Alan Milburn (2000) firmly establishes the preceding in referring to the â€Å"†¦ National Service Framework for Coronary Heart Disease†¦Ã¢â‚¬  as the nation’s â€Å"†¦ blueprint for tackling heart disease†¦Ã¢â‚¬  Mr. Milburn’s statement goes on to add that the new ‘Framework† is based upon the understanding and recognition of past inequities and shortcomings which this new initiative addresses, along with the understanding of â€Å"†¦ the importance of modern prevention and primary care as well as the contribution of the more specialized services.† The fact that the National Health Service has undertaken this modernization program clearly indicates that it understood and recognized the prior user experience, service quality and fairness/justice components needed considerable improvement. Regardless of how deeply one would delve into the inequities of the past, there could be an argument made for areas and points that were not covered, as the list is extensive. And no matter how comprehensive the present system is, it is an evolutionary framework that will have its own initial and ongoing issues and inequities to face as well as resolve. The difference between the two systems is that the present one was developed with the understanding that it will continue to improve upon itself as it learns from its base of past expertise. In the complex and ever changing world of medical care, the preceding is all that can be asked from its healthcare agency, with the understanding that no matter how comprehensive the plan, modern changes and developments can and will render segments as obsolete, thus the need for a built in foundation that incorporates this as its framework. The very fact that past user experience, service quality and fairness/justice had shortcomings, along with other points is the reason behind the new Framework initiative, and this in itself is a progressive view that is responsive to the needs of the populace, which is the rationale for the government’s existence.

Liposuction – a way of getting rid of that extra fat on the body! In the busy world of today, managing time in our daily routine has become the most difficult thing to do! Because of which, people barely get time to exercise and keep themselves fit. And to add on to it, canned food exists in opulence! In a world which is ideal, Liposuction (Fat removal) would not be needed. Everyone would eat moderately, in the appropriate quantities and would exercise. But the world is far from ideal! And hence, with each passing year, Plastic Surgery for unwanted fat removal or Liposuction is becoming more and more favourite among the people! Everybody wants to look fit and healthy. Being overweight can be a factor of embarrassment and may be a social stigma. Obese (overweight) people when stigmatized, may even feel a bit low on confidence! Hence, to get rid of this embarrassment and in order to look presentable, such people seek for Liposuction/ Fat Removal treatment. Let’s find out more about this ‘Liposuction’ treatment: What exactly is Liposuction? The literary meaning of the term â€Å"Liposuction† is removal of fat from the body with help of suction. At the time of this procedure, thin, small, blunt-tipped tubes (cannula) are inserted through small incisions (cuts) in the skin. The doctor moves the tubes around under the skin to direct at specific fat deposits. The fat is thus suctioned out through these tubes. Non-surgical Liposuction: A substitute to surgical liposuction wherein different technologies are used to liquefy fat using non-invasive methods like lasers, ultrasonics and injections of chemical agents. With the advent of newer modern and improved techniques/ methods, Liposuction has become much easier, safer and less painful. These modern techniques are as following: Tumescent Liposuction: The area where the tube is to be inserted, a local anesthetic is used for numbing that particular area from where the fat is to be suctioned out. After that, a large amount of an anesthetic solution consisting of epinephrine and lidocaine is injected into the fatty tissue before suctioning out the fat. General anesthesia may not be required in this kind of procedure. Ultrasound-assisted Liposuction: In this method, ultrasound is used for liquefying the fat, thus making the fat removal easier. This kind of technique may prove beneficial in case of removing fat from the sides, upper abdomen and back. Laser-assisted Liposuction: In this method, low-energy waves are utilized for liquification of the fat, which is then removed with the help of a small cannula. The procedure is generally carried out as an outpatient procedure in a properly equipped Doctor’s office, surgical center or a hospital. Only when a large amount of fat is required to be removed from the body, an overnight hospital stay would be needed. In such a case, a deep sedation or general anesthesia with a local anesthetic may be administered. Why is it done? The chief motive behind Liposuction is to re-shape one or more regions in your body and NOT to reduce body weight. The â€Å"problem† areas which do not react to diet and exercise, are tackled by carrying out Liposuction. These areas are namely – the outer thighs and hips in case of female and the waist and the back in case of men. Also, the areas that are generally treated using Liposuction are – the face, neck, back, abdomen, upper arms, legs and buttocks. Liposuction may at times be carried out along with certain other Cosmetic Surgery procedures viz. â€Å"Tummy tuck† (Abdominoplasty), Face-Lift or Breast Reduction. A few clinical conditions may be treated with the help of Liposuction, which include the following: Abnormal enlargement of the male breasts (Gynecomastia or Pseudogynecomastia) Benign fatty tumours (Lipomas) Excessive sweating in the armpits (Axillary hyperhidrosis) Problems with fat metabolism in the body (Lipodystrophy) Liposuction is not used to get rid of Obesity. It will NOT help to clear out cellulite or stretch marks. What to anticipate after the treatment? After the procedure has been carried out, the treated area is tightly wrapped in order to diminish swelling, pain and bruising. Elastic bandages and tape, a special girdle or some type of fitting garment may be used, based on the area that has been treated. The patient may need to wear the compression garment for about 3-4 weeks. At least for the first 7-10 days, a lot of bruising and swelling is expected to occur. The fluid may evacuate from the site of incision for a few days. The patient may be prescribed antibiotics to reduce the risk of infection. After the procedure has finished, and the effect of anesthesia and sedation has been subsided, most of the patients may resume their daily activities as and when they feel comfortable. In case of larger areas undergoing liposuction, recovery may take a bit longer. Outcomes of the Surgery: When carried out in small regions on the body, Liposuction may give out the best desired results. But in case where a person regains weight after undergoing the procedure, the fatty bulges that were removed earlier are most likely to reappear or appear in another place. There may be quite notable changes observed in the body contour immediately after the surgery. It may take several months to a year for the full effects of the surgery to show up. Liposuction does not necessarily tighten the skin around the treated region. After the fat removal has been done, the skin around that region may become a bit loose. For the skin to tighten, it may take up to 6 months. In case of young people, skin retraction is faster. Every surgical procedure has its own advantages and disadvantages. And when it comes to Cosmetic Surgery, it’s no different! There are some risks that are involved with the procedure of Liposuction. Let’s have a look as to what complications may arise after the Fat Removal Surgery: If Liposuction is carried out by an experienced Cosmetic Surgeon in a well equipped surgical setup, it is usually safe. In cases, where a larger amount of area or more than one area have undergone the surgery, the chances of complications arising are more. Bruising, swelling (which is temporary), numbness and soreness in and around the region treated Minor scarring and irritation at the site of insertion of cannula Rippling or baggy skin Certain less common risks include: Uneven skin surface over the region treated Permanent change in colour of the skin Damage to the skin and the nerves, particularly in case of Ultrasound-assisted Liposuction It is very important for people to be careful and not gain extra weight after the surgery. As it may result in fat deposition in certain other parts which are deep inside the body, such as the internal organs like heart, liver etc. Such type of fat deposition can be more fatal. Dangerous risks include: Blood clots or fat clots, which may travel to the lungs (Pulmonary embolism) Excessive blood or fluid loss which may result in Shock Pulmonary edema – fluid accumulation in the lungs Toxic reaction to injected solution, particularly in cases when larger areas are treated. People who have severe heart problems, or blood clotting disorders or pregnant females should NOT undergo Liposuction procedure. Things to note: Liposuction is NOT a mean for reducing weight and it is never an alternative to exercise and a balanced diet. As a matter of fact, most of the Cosmetic Surgeons are of the opinion that the best candidates to undergo Liposuction would be healthy people who are at or very close to a healthy weight but who have stubborn fat deposit which does not respond well to exercise. Liposuction should be carried out only by an experienced Cosmetic Surgeon who is well-trained in Liposuction and knows well how to tackle the complications during surgery.

Flyboy, Inc :: essays research papers

Flyboy, Inc Flyboy, Inc which is successful manufacturer of aircrafts wants to expand its market to Pumonia.(a small oil rich kingdom that was once an Italian colony). The government would be the principal purchaser, along with some royalty private families. It is not possible for Flyboy to enter the marker without a local representative. Flyboy is aware that â€Å"grease payments† and lavish gifts to customer is Pamonia is customary. Before Flyboy can make any decisions in expanding to Pamonia, several aspects need to be carefully analyzed and planned out, to avoid future troubles and make a smooth transaction. Both the advantages and disadvantages of this transaction should be considered. Typically the advantages of effectively expanding abroad outweigh the disadvantages and therefore the advantages will only be boldly stated. More time will be spent in analyzing in more detail the minuses of this transaction and showing how these disadvantages can be overcome by Flyboy. The two major advantages of Flyboy moving into Pamonia include: The opportunity for Flyboy to expand its geographic scope of its marketing. And the local presence permits Flyboy to maintain the aircrafts sold abroad, which can lead to better customer service and translate in to customer loyalty and satisfaction. This by the same token crates an increase in revenue. On the other side of the coin- the disadvantages or not so attractive side of the transaction are the following: By setting up and hiring agents (dependent or independent) the company has subject itself to local laws and regulations. There are many different international laws that help out a firm when entering a new foreign market, but there are just as many new host country regulations that Flyboy should consider before making any critical decisions. An example of one of the regulations that Flyboy should consider, especially if it will be in charge of marketing, is the regulations for advertising abroad. Adverting regulations are established so the host country can make sure that the new company complies with regulation such as publishing the truth in advertising, the language used in the ads, and so they can have some control over the specific content. Flyboy should have very well planned marketing strategies and local marketing considerations. Since many of the advertising regulations abroad are not even a stated law, but rather an industry code observed by the local marketing organizations; the best thing any new foreign company should do is seek legal advice from local practitioners and fashion local advertising appropriately.

Developing language skills Essay

1. INTRODUCTION Throughout the last several years English teaching course books have become the essence to learning the English language successfully. There has always been a major necessity to reading, listening and writing but recently educators have found that communicative competence is an important asset that needs acquiring. According to this latter statement, recent course books are equipped with all four skills in order to achieve a proficient level of English. However, due to new discoveries such as the learner-centered learning or Howard Gardner’s Multiple Intelligence Theory , many books are inclined to the different necessities that better suit the  student. Here, for example, we are presented with two very different books directed to teenagers. In the following course books: Bachillerato book Made Easy and the Basque book ‘Botellà ³n!’ we will intent to make various contrasts and comparisons amongst the four major skills to English language learning. 2. METHODOLOGIES We must realize that all course books have many methodologies.. We have seen in Methodological Approaches (See Funiber Subject 1) that Marianne Celce-Murcia quotes that â€Å"a historical perspective needs to be taken into consideration to be able to evaluate innovations effectively†. As we can see there has been an immense amount of detail added to language teaching from the early 19th century when comparing the Grammar – Translation method to the newly adopted approaches although there are still signs of the methodologies present within the newer books. Here are some: 2.1. TABLE MADE EASY BOTELLON! both Grammar-Translation Method Exercises to translate into L1 Use of dictionary Direct Method No use of mother tongue Reading Method Lots of reading material Structuralism Plenty of drilling and repetition Contrastive Analysis â€Å"Bachillerato† will focus on common Spanish errors, eg. DO/MAKE The theme/subject is inclined to a Spanish saying: botellà ³n.. Behaviourist Stimulus, response, reinforcement: activities Cognitive Approach Rules are made clear first before practice (TPR) CALL The course book is equipped with extra material: resource books for teachers and a website TPR â€Å"Learn language through doing† CLL Extensive list of themes: appreciating the learners needs. – No textbook. Natural Approach – Contain all four skills – Teacher support. Lexical Approach Vocabulary importance. Audio-visual Method Meaningful communication and social contexts. 2.1.1 THE LEARNING THEORIES IMPLICIT This chart shows both course books seem to have adopted some essence of the older methodologies. Nowadays approaches are more familiar where teachers can choose a method that will better suit the learner. However, our next research will be on : integration and segregation of reading, writing, listening and speaking skills. 3. INTEGRATION First: the meaning of integration is the usage of all four language skills simultaneously in various activities. Some exercises begin with reading, perhaps a follow up of discussing the article and finally concluding a written summary of the text. By doing all three activities we are utilizing the skills of reading, speaking and writing. As Dr Garza quoted it â€Å"most teachers recognize that the four language skills support each other and are found together in real-life language use†. Also, none of the separate language skills are ever used in isolation (Funiber, Developing language skills in the classroom). Now we understand the significance, we can continue to analyse this method in the books. 3.1. EXTENT Made Easy, from an external perspective looks as though the skills have all been segregated but in fact they have all been integrated. The reading, which is divided into a before, while and after reading which are entwined with various grammatical activities for preparation. However when you look at an internal view of the course book we see that there is a high level of integration with the four skills. Take the writing section which has various grammar exercises (Language/Vocabulary) Assignment – DLSC beforehand to ensure understandability of the learner which also holds a cognitive approach to learning according to Chomsky. Here, reading and writing are both merged then followed by reinforcing activities. As we have learnt reading in traditional terms at least, seems to be a natural bedfellow of writing (Funiber). Lastly, we have a division of the listening and speaking activities from an outer look in the last page but they are  however united through the theme of the subject which locks them together. On the other hand, the Botellà ³n book is relatively distinctive. Firstly, the format that is uses is generally integrating reading and plentiful of brainstorming writing activities with the final intention of speaking. However there are activities of listening which is integrated with writing. However there is only the one activity (2) that is segregated which is the skill of speaking as is the final activity which perhaps helps the teacher to evaluate the extent of the learne rs new acquired knowledge throughout the course. 4. PRODUCT AND PROCESS ASPECT However, there are some similarities worth mentioning between the two course books. They both take a process approach which has the student â€Å"working up to† the final contribution. A process approach tends to focus more on various classroom activities which promote the development of language use: brainstorming, group discussion and rewriting (Steele, 2004). In the Bachillerato book Made Easy on page 61, we have: before and after writing preparation: an insight, planning, mind mapping, writing first drafts, feedback, editing and evaluating.Chen for example states that â€Å"these studies have quantitatively measured improvements in learners’ test scores following the completion of a strategy training programme† (2007). Furthermore, the Botellà ³n book also includes a process approach but in a broader sense and tends to cover most of the book with an abundant amount of brainstorming activities that drive and lead to a final proposal (writing) and a discussion part (speaking) at the end. As Lynch quotes: â€Å" the route one takes to that goal† (1996:148). To compare: 4.1.1 TABLE Process writing Product writing Text as a resource for comparison Imitate model text Ideas as a starting point Organization of ideas are more important than ideas themselves More than one draft One draft More global, focused on purpose, theme, text type i.e. reader is emphasized Features highlighted including controlled practice of those features Collaborative Individual Emphasis on creative process Emphasis on end product * Table 1: Product and process writing: A comparison (Steele 2004 p. 1) 5. AUTHENTICITY Now looking more closely to the aspects of authentic/genuine exercises. The significance of an authentic text: some researchers have gone on to say: â€Å"authentic materials are materials that we can use in the classroom and that have not been changed in any way for ESL students† (Sanderson, 1999). Harmer (1991) defines authentic texts as â€Å"materials which are designed for native speakers; they are real texts; designed not for language students, but for the speakers of the language†. Authentic texts is language used by natives which have not in any case been manipulated by authors to suit the level of then learners. Although, what matters is the response and expression of the learner, if it in accordance to the text then the response has been made authentic as once quoted by Widdowson (Funiber, Developing Language Sills in the Classroom). In Made Easy, there are many reading activities. In the text â€Å"Making and keeping friends† we can see that there is a previous activity to help the learner think and analyse the text before reading; predicting. According to Revell and Breary, a way of dealing with this problem is to get the learners to predict the main points of the text (Funiber). After the reading there are questions to be answered straight after the comprehension: if we immediately ask questions then we are denying the chance to give an authentic response (Lynch 1996: 124-125). The next â€Å"authentic† text would be the possible newspaper or magazine article (pag 63) which has probably been falsified to a certain extent to suit the level of the learner. In the  speaking, on page 67, they are able to give their own opinions in relation to the listening previously heard which allows their own expressions to be considered. The listening provides the learner with many different ideas for brainstorming. However, they are not real life situations, there is no genuine media and there is an exclusion of body language and facial expression and thus there is no possible reply (Funiber). In the Botellà ³n book, we are presented with a real problem of teenage street drinking which induces a genuine problem. The first speaking exercise allows the learner to give real feedback with an authentic and genuine response. Throughout the unit we have, as mentioned above, many reading activities: real life opinions, newspaper articles and a diplomatic meeting. This all seem extremely genuine but to what extent is unclear. On another positive note, we have two You tube debates: Pregnancy Discrimination and The Iraq War. These last two are very opposite to the general and ordinary listening we are used to and they are in fact impossible to manipulate. Following this virtual debate, we have a more general listening about p sychology with Dr. Lindee which although is a very universal reciprocal activity it may have some essence of credibility. 6. SIMPLIFICATION Widdowson says that â€Å"text simplification for second language learners is the adaption of a â€Å"genuine text† in order to facilitate reading and comprehension skills. Some authors claim that Assignment – DLSC authentic materials (genuine) are often too hard for students who read at lower levels .Though is controversial issue, a genuine text is not necessarily better than an adapted one, what matters if the student responds to it as he would in real life.† On the one hand this will benefit the some learners, as by manipulating the text to suit the learners interest this will stimulate their motivation and interests. However, Honeyfield (1977) says that the two principal aspects of text simplification, namely simplifying language and simplifying content, produce material which differs significantly from ‘normal’ English in the areas of information distribution and common structure. By altering the language,it reduces the colloquial and â€Å"realness† of the language. Now the question remains as to how do we  identify if the text has been adjusted? Swaffar (1985) says that the primary intent of an original text is to communicate meaning, and in her view, authentic messages which perform this function have the following characteristics: authorial cues, repetition, redundancy, and discourse markers. She claims that simplified texts do not have these characteristics because they have a â€Å"pseudo-intent†, which is to teach language, rather than to communicate. Made Easy has three very different texts: firstly on page 61 the text holds an easy vocabulary, short sentence structures, redundancy and a a simple content of topic. On page 63 however, in activity 6 we have a newspaper report, we are given information with an unsophisticated vocabulary and a structure that is in relation to the grammar explained in the previous activity: the reported speech. Lastly, there is an essay written in an academic format, supposedly by a native adolescent. There are longer sentences with subordinate clauses and a wider scope of vocabulary . All three text show some sign of simplification which is not ideal because as Willis says, in developing their communicative skills learners need to become aware of the choices realised in genuine language use in order to create appropriate meaning (1996: 26). This opinion puts learning on fluency. The Botellà ³n gives more of a realistic and pragmatic cognizance because all of the texts represent â€Å"real life† opinions which should all interaction between natives should be genuine. Firstly, on page 64, activity 3, we have 7 different views about the subject of alcohol. By analysing the content we have a very colloquial type of language expressed by native English foreigners living in Spain. Secondly, on page 71, activity 6, we have more viewpoints but there is a more complex vocabulary and structure with more detail, plentiful of subordinate clauses and some acronyms. Lastly, on page 74, activity 7, we have more opinions but these are inside quotation marks which indicate direct speech and should be understood as a natural and spontaneous spoken English. The amplest difference about the two books when identifying these concepts is on page 77 of the Botellà ³n book on activity 8: There are two virtual debates (Pregnancy Discrimination and the Iraq war) which are provided to the students to watch from the web. This is the closest encounter we  have to real conversation. McCarthy and Carter explain that â€Å"’language in action’ involves participants in using language to refer to action in an easy and unproblematic way because they are taking place before their respective eyes (pag. 209). 7. SKILLS The next subject is the relationship between the work and learning/practice of grammar: When teachers first began to adopt a communicative approach to foreign and second language teaching, â€Å"learning communication† was often presented as an alternative to â€Å"learning grammar†. We noted a strong sense of convergence between stated beliefs and actual classroom practices. Having our self-experienced English language learning by explicit instruction on the rules of grammar, the belief that grammar teaching should be integrated into speaking, writing and reading. belief that grammar is central to language learning and direct grammar teaching is needed by their EFL/ESL students† We think this particular type of study vitally important especially in light of the results of the recent Richards, Gallo, and Renandya (2001) survey that suggest evidence of divergence between teachers’ stated beliefs and actual classroom practices related to grammar teaching. 8. PRODUCTION: ORAL AND WRITTEN In Bachillerato Made Easy there is a continual relationship between production (oral and written) and grammar because we can see that the step includes a written part where the students write sentences to take into account the ways to report what someone has already said, then in an oral practice they report the message using a reporting verb and making some changes in tenses pronouns, adjectives and adverbs. In â€Å"Botellà ³n† there isn’t a relation between skills and grammar because the unit doesn’t show any grammar description. They have a brief model to write, read, speak and listen but they don’t have the grammar reference to follow the different skills. What are the opportunities for production do both units provide? Oral communication is a two-way process between speaker and listener where both the speaker and the listener have a positive function to perform (Byrne  1986: 8). So speaking is therefore an interactive process but we have to recognize that there will be times when the speaker’s role will be essentially passive which is emphasized in McGregor’s model of collaborative discourse (see Section 2.2.3) Furthermore writing is labeled as written production and is one of the branches, it is a skill that students must develop. When expressing oneself in a language, this is only done in an oral fashion; written communication is extremely important in language learning. So both units provide their students with situations that allow development and progress in the four skills: Bachillerato Made Easy the unit provides opportunities with a group work, self-access and Presentation – Practice –  Producti on, for both production skills (oral, written) the unit tends to be teacher-centred, as the teacher leads the activity and provides necessary information. Furthermore it is a student centred activity because the learners in some steps are able to decide what to say, and how to say it, for example: for oral production the learners start discussing with a self-assessment task in two different exercises. In the first exercise learners have to reflect about their behaviour in given situations and in the second part they have a free group discussion about the same topic which is presented in all the unit and provide the learners with the necessary structure, vocabulary and grammar (previously taught). ‘Botellà ³n!’ provides opportunities with interaction where the learners work in groups or independently where they have the chance to work together and interact autonomously and the teacher acts as a facilitator by monitoring their work. For example for the written part they use the steps in the reading part to refute a diplomatic way the topics given. Now the learners are totally trained for talking about different points of vi ew. As we know there are three main stages in any unit: Presentation, Practice, and Production. A unit which includes all these stages can help learners to learn more efficiently. 8.1 TYPES The presentation stage involves explaining the aims of the unit so that children know what they will learn and why. It is also during this stage that the teacher explains the new language, including both its meaning and  form, and how to say or write it correctly. The goal of the practice stage is to help the children use the new language you have just explained to them. It is at this stage that error correction is most important. The final stage is the production stage. This can help motivate children to communicate meaning with the new language. Children should experiment with the language. For example in Bachillerato Made Easy, they write an essay but in the part for production it is required to follow the steps to create the essay: description, narration, exposition, and argumentation) or it is better to write a paragraph or notes for a letter to produce learning.In â€Å"Botellà ³n† they make a diplomatic discussion, this part requires more group work and pair work to achieve more examples of communicative language. 8.1.1. ACTIVITIES Assignment – DLSC The variety of the activity types provide opportunities for students to build Awareness or Conceptualize understandings related to the learning. They help the learners to apply their knowledge of the contents using a variety of processes and techniques. The four skills work in tandem when the activities that require their use are designed to support learners in the process of learning, creating and producing a specific product. The Bachillerato Made Easy unit presents the following activities for the speaking section (oral): dialogues, role play, talking about themselves related to behaviour in different situations that mention generalization and advice to take into account in our real world to be good friends. In this activity students are allowed to answer questions using their own words. On the other hand, a written section follows these activities: Written practice to responding to questions that are related to friendship. In the speaking section the activity discusses some of the issues, factors and solutions for the problem. Apart from that the other activity is to work individually, whether they agree or disagree and to state their own reasons about the proposed solutions. The last activity is a discussion in groups, giving for and against arguments. In the written section the unit uses a discussion organiser in a written practice where the students have to write some notes proposing a solution which could be appropriate for everybody on the subject of botellà ³n. 9. OPINION AND CONCLUSION We can say a textbook is only as good as the teacher who uses it. A textbook is just a tool, in our teaching arsenal. Sometimes, teachers over-rely on textbooks and don’t consider other aids for the classroom. Some teachers reject a textbook approach to learning because the textbook is outdated or insufficiently covers a topic or subject area, but we know that a book or a unit is very important to learning the language. So we prefer both units: Bachillerato because this unit is considered Authentic and Genuine, the unit works with the four skills and other points such as grammar which are vital to learning the language. Furthermore the unit has different activities for each skill. On the other hand the unit â€Å"Botellà ³n† because it is algo genuine although this unit is more student centred. In this case it is focused on each student’s needs, abilities, interests, and learning styles, placing the teacher as the facilitator. BIBLIOGRAFY 1. Berliner, D. C. (1987).

Benjamin Banneker Analysis Essay

Benjamin Banker shifts from respectful to cynical using allusion, repetition, and negative diction to prove that since all men are created equal, slavery must come to an end. Allusion provides examples for the author and is used to assist the reader with relating to and understanding a point or message. It makes the reader feel connected, and think along the lines of the author. Banker alludes to the Declaration ofIndependence to remind Jefferson of the equality of all American men. This strategy acts as a reminder, and shows Jefferson that he, Banker, is intelligent and aware of his rights. Allusion is also used in the letter when Banker refers to Job, and his advice to his friends about enlarging their hearts with kindness. Thus, explaining how Banker wants Jefferson to feel toward slavery while still maintaining respect. Next, to illustrate the shift in tone, Banker uses repetition.Repetition acts as a sound strategy, reminding the reader of an idea or thought. In this letter, the word â€Å"Side is repeated six times. This is done as a sign of respect toward Jefferson. Repetition of â€Å"sir† sticks in the readers mind and illustrates the principle of status in eighteenth century America and the lack of equality between men. The utilization of negative diction is powerful, and can alter the feelings of the reader. This strategy transformed the initial tone of respect to a cynical tone.Banker for example, uses the words â€Å"groaning captivity', â€Å"cruel oppression†, and â€Å"fraud† to describe slavery and to convey an inhumane and cynical feel. These words make the reader portray Jefferson, and slavery, in a negative light. These three strategies that Banker utilizes show how Jefferson own words that â€Å"all men are created equal† contradict the actions of America, by slavery being allowed. Each strategy alters the thoughts and emotions of the reader, swaying the, to agree with Banker and his liberating beliefs.
