Singapore Airlines: Business, Marketing and Operations

Singapore Airlines: Business, Marketing and Operations This paper study is based on Singapore Airlines (SIA), in this case study the project has discuss about the SIAs Business, Marketing and operational strategy, what are the changes is the SIAs facing in future, how this airline company has changed its strategy and how this airline from a small country-state with a population of about three million people, on an island no larger than the Isle of Man, earn a reputation for being the most constant money-making airline in the world, in spite of the various world-wide recessions. The paper study also discuss about, how the Singapore Airline retained employees and the customers. QUESTION 1: Evaluate SIAs Business, Marketing and Operational Strategies and assess their effectiveness in relation to the competition? Over the last decade Singapore Airline has grown from a local airline into one of the worlds leading passenger and cargo carriers. In an attempt to survive, many of the organization which is working in the same business tried to observe and investigate the approaches or strategy which are using by Singapore Airlines (SIA, 2007). Finally it became clear and understandable that SIA are more competitive because of its business and operations strategy. The long term growth of a business design to provide and maintain shareholder value is called the business strategy. So, this part of the paper contains the business, market and operation strategy of Singapore Airlines. As we all know the SIAs has developed a status for being an industry innovator as well as doing things in a different way than its competitors who are in the same industry line, for example, As the study says SIA was the first airline to introduce free drinks, a choice of meals and free headsets back in the 1970s. Not only this, the Singapore airlines are the first who start a two year programme to install Kris World, that is a new in-flight entertainment scheme, for passengers in all three classes of its Megatop B747s. KrisWorld provides around 22 channels of video entertainment, around twelve digital audio channels, around ten Nintendo video games (Nintendo was best known for console industry and famous for home video game), and always alert the destination information and provides a telephone at each seat. By using this innovative ideas and creativity techniques the SIAs has done wonder in this airline business and earn a reputation for being the most consistent money-making airli ne in the world. Not only this, SIAs has done many changes in the history of airline and they provide numerous innovative ideas and doing things differently than its competitors. SIAs is the one who spend lot of millions in order to install KrisWorld movies; by doing this they had given an amazing entertainment to their customers while traveling and this lead to make them a different from their competitors and by adding this KrisWorld they are the first one to do so and this types of strategy help them a lot in becoming a number one in these business. SIA is the first in the market for discoverer and performer of the mostly innovative live teletext news service (KrisNews) and also for an interactive in-flight shopping service for its aircrafts. These creative and innovative developments by SIA, eventually won numerous awards for the best air lines. SIA was the first airline which bought a collection of finest chefs from all over the world to serve best in-flight cooking for its passengers as well as it was the first airline which tried to accomplish the wants of individual passengers by launch the special meal service with lighter and better options plus the unique in-flight meal service which is specially introduced for young flyers and enabled them to choose their desired meals up to 24 hours before the flight departure. Besides that, SIA started to update its menus monthly and even weekly to create an impression among its frequent travelers and also to keep track of flyers tastes. These were the main line of attack for SIA to compete among its competitors in the market and also to shore up its business strategy1. The main success of SIAs is Singapores Changi airport, Changi is situated in eastern end of the Singapore. Changi airport is one of the world busiest airport QUESTION 2: Using change management models evaluate how the company has changed; in strategic terms. QUESTION 3: What challenges is SIA facing in the future. What should SIAs business and operations strategies be for the future and why? Provide justification for your recommendations. As we know that SIAs is the one of the leading airport in the world but due to the large number of competitors in the world. SIAs have to maintain their top ranking in the future by maintaining their operations and business strategy and by developing more innovative ideas. The challenges which a SIA facing in future is mainly due to their competitors, as we all know in airline business the profit is very less and its mainly because of growing airline industry, passengers have many choices to select the low fare flight, so they must provide the better facility in a lower price that may affect their capital turnover. Recession is also the one of the factor for affecting then in future. Like in recession, there is a reduction in number of fliers. In future there is my advance airplanes/crew because of the competition and so the availability of the best crew is very important. There are more challenges that airline industry is facing like escalating costs and stiff competitions. As this part of the paper contains that which type of business as well as operations strategies should SIAs makes for their future and which makes them different from there competitors. Before going to this we must know about the operations strategy, operations strategy is the total guide of decision made the management which leads to the long-term growth for any type of operations, it is the long term process. Basically operations strategy is the method or tools that help us producing goods and services to the consumers. Operations basically deal with the producing or delivering of goods. This paper study discuss the competitive strategies of Porter, In 1980s Porter has argued that there is two types of competitive advantages which can be shared with either a broad or narrow competitive scope to create four well known business strategies: 2 Cost leadership, Differentiation, Focused low-cost, and Focused differentiation The Porters four competitive strategies are shown in table below:- Competitive Advantage Lower Cost Differentiation Cost leadership Differentiation à ¯Ã†â€™Ã… ¸ broad target Low cost focused Focused differentiation à ¯Ã†â€™Ã… ¸ narrow target Cost leadership technique or strategy is normally used by the companies for generally generating the profit even though the low price of the product or the services offered. In this strategy company mainly focused on the decreasing of price and retaining their old customer and generating the new one, so by applying this rule to the airline business SIAs have to take some initiative for lowing there prices in spite of that providing the full facility to their passengers. By doing this the SIA is always be a head from its competitor in present as well in future because doing this the high, medium and even low class passenger get attractive towards it and SIAs will make even more profit than earlier. Differentiation strategy, in this strategy a companys offers a service that consumers perceived it as a different and ready to pay a high amount or cost for that. So, SAI have to innovate some new facilities like new entertainment programs while travelling and some advance technology features with some extra cost, and it must be different as well as a new thing for passengers so that they are ready to pay a high amount for it. Or do offering the old facilities but offered it in that manner that passengers are ready to pay a high amount. This type of innovation or creativity make them different from there competitor and good for future also. Focus Differentiation strategy focus on a narrow sector and within that sector, they are attempting to achieve either a price advantage or differentiation. The principle is that the sector which is focusing must be better served by entirely focusing on it. So, SIAs must use this strategy for be a top in their business by focusing in a small small sector and offered better services to the passengers and then they will definitely be a head in the airline business. Reflection on Career Goals: Becoming an Ophthalmologist Reflection on Career Goals: Becoming an Ophthalmologist 1. Please provide evidence of activities and achievements which demonstrate your commitment to a career in this specialty and/or which have led to the development of skills relevant to a career in this specialty.(250 words) My inspiration for becoming an ophthalmologist stemmed from working in DARUL-HIKMAT DARUL-SHIFA, a charity eye hospital in Pakistan, which I have attended biannually since first year in medical school. There I observed how a small procedure brings a remarkable improvement in the quality of a patients life. Out of my own interest, I undertook 2 ophthalmology electives. I was privileged to observe practice on an incredible elective at MOORFIELDS EYE HOSPITAL. It was a great experience and further motivated me to become ophthalmologist. I achieved Distinction in Ophthalmology during my MBBS. As a Foundation year doctor, I regularly attended eye clinics and theatres in my free time. I did a week of a TASTER SESSION and managed to arrange a SPECIAL MODULE in ophthalmology during my GP rotation. I have made several international presentations and have published in peer reviewed journals. I have excellent hand to eye coordination and dexterity. I am competent in Objective Subjective Refraction. The combination of medicine and surgery, along with the variety of cerebral and fine motor skills necessary has drawn me to the specialty. It is the only specialty that has satisfied me to practice medicine at the highest level. Sight is the most valued of senses for many people, and to be in a position to improve and restore sight, as well as prevent eye disease, gives me great pleasure. I am a dedicated, hardworking, and energetic person. In addition, I have passed RCO exams and my experience in ENT, neurosurgery, diabetics and oncology make me a great candidate. 2. Please provide details of outstanding achievements outside the field of medicine. (250 words) I have regularly arranged clinical courses for the junior doctors and GP since 2008.

(250 words) I was elected as a Sports Coordinator at Medical College in my final year, which was a great honour and position of responsibility. In order to make this successful, I needed a good team and representatives from each year, whom I appointed. Working through the team and using my leadership skills, I was able to make significant changes. I reformed the Sports Society and devised its rules and regulations. For the first time since its foundation, I arranged fixtures with other universities and introduced new sports. I took on board ideas from team members and organized sponsors and a concert to generate funds. Our efforts improved the colleges sports reputation. This was because of the good management, delegation of responsibilities to team members and proper use of the recourses generated. I also captained the basketball team and was awarded â€Å"Colours.† This experience not only improved my team working and leadership skills, but also improved my ability to perform under pressure and make clear decisions. 5.Teaching Experience: What experience do you have of delivering teaching?

May 2009 Communication and interpersonal skills: Please give a recent example that demonstrates that you possess these skills. (150 words max) A 59 year old gentleman was referred over the weekend with a six month history of left temporal ache. All the examinations and bloods were normal, except for a disc swelling on his left side. I informed my consultant and devised a plan. Then, I liaised with the ENT and on call radiologist to review the patient. I kept the patient and his partner informed about all the progress throughout this time. After arranging an urgent scan, which showed a mass compressing his orbit, I arranged for the admission and booked theatre for removal of the mass compressing orbit. As the focal point of communication between concerned groups, I enabled us to work as a large team, efficiently and effectively, to save the patients eye from future complications. My ability to communicate and delegate facilitated the effective success of a multi-disciplinary team approach to patient care. Initiative: Please give a recent example that demonstrates initiative. (150 words max) In October 2008, I attended a busy eye camp in Pakistan. During my stay, I was astonished to find that operations are cancelled on-table by the surgeons due to high IOP. Only high risk patients were having their IOP checked due to high patient turnover. This resulted in a huge waste of resources. After discussion with the management, I took the initiative to provide a solution to this problem. After research and discussions with senior doctors visiting the camp, I proposed to use a puff tonometer to check IOP of all patients undergoing surgery. This method doesnt require extraordinary skill to use, hence it is effective in a busy camp. This proposal was accepted by the supervisors. It had been a great success with surgical cancellations dropping by more than 95%. I received a letter of thanks. Making such a difference in patient care makes me proud. PAPER 2 Describe how you realised that you wanted to become an Ophthalmologist? [Edit] My inspiration for becoming an ophthalmologist stemmed from working in DARUL-HIKMAT DARUL-SHIFA, a charity eye hospital in Pakistan, which I have attended biannually since my first year in medical school. There I observed how a small procedure brings a remarkable improvement in the quality of a patients life. Out of interest, I undertook 2 ophthalmology electives and I was privileged in observing practice on an incredible elective at MOORFIELDS EYE HOSPITAL. It was a great experience and further motivated me to become ophthalmologist. Achieving a Distinction in Ophthalmology during my MBBS, I joined Rawalians Research Forum during my final year in medical school, where I published two research papers. Since then I have been actively involved in audits and clinical studies. I have presented 14 papers in international and national conferences. In addition, I have several published articles in many journals. Most notably during the Haematology, I was involved in ‘randomized control trials. As a Foundation year doctor, I regularly attended eye clinics and theatres in my free time. I did a week of a TASTER SESSION and managed to arrange a SPECIAL MODULE in ophthalmology during GP rotation. I have excellent hand to eye coordination and dexterity. I am competent in Objective Subjective Refraction. In my recent job I have done 53 Phacoemulsifications,6 Squint Surgeries, 23 IV injections, and 64 argon YAG laser procedures. The combination of medicine and surgery, the variety of cerebral and fine motor skills necessary has drawn me to the specialty. It is the only specialty that has satisfied me at the highest level. Sight for many is the most valued of senses and to be in a position to improve and restore eyesight, and prevent eye disease gives me great pleasure. I am dedicated, hardworking, and energetic person. In addition, I have passed RCO exams and my experience in ENT, neurosurgery, diabetics and oncology will make me a great candidate. What do you think are the main issues in solving global blindness by 2020? [Edit] Approximately 314 million people worldwide live with low vision and blindness. 90% of these blind people live in low-income countries. 80% of blindness is avoidable. Without effective, major intervention, the number of blind people worldwide has been projected to increase to 76 million by 2020. The major causes of blindness in the world are cataract (50%), refractive errors (15-30%), Trachoma, Onchocerciasis, Glaucoma, Diabetic Retinopathy, Age Related macular degeneration. According to WHO, restorations of sight and blindness prevention strategies are among the most cost-effective and gratifying interventions in health care. In 1999, WHO launched VISION 2020 The Right to Sight. It is a joint programme of the World Health Organization (WHO) and the International Agency for the Prevention of Blindness (IAPB) with an international membership of NGOs, professional associations, eye care institutions and corporations. It aims for control of avoidable blindness by 2020; to achieve the aim the following issues need to be addressed. HR development: adequate and purposeful training of all eye care personnel is a key factor. Apart from ophthalmologists, the ophthalmic nurse, ophthalmic medical assistants and especially refractionsists should be recruited and trained appropriately. Infrastructure Equipments development: facilities should be equipped according to the tasks. Local entrerpreaunership should be encouraged to participate to reduce cost and enhance sustainability. Awareness Education of local community: community participation is vital and this can be achieved by creating awareness in the public about the diseases and the facilities available to treat and prevent them. Funding: regular and new funding sources should be explored. Outside medicine, what personal attributes make you a good candidate for a career in Ophthalmology? [Edit] I possess combination of qualities through which I have not only achieved over and above the required competencies mentioned in the RCOphth curriculum for ST1 and F2 but also a good working relationship with the colleagues to prove as a good and successful ophthalmologist. I maintain good rapport with patients. During my foundation training, I had experience of caring for terminally ill patients, breaking bad news and discussing the patients care and resuscitation status with their family, which I was able to do in an empathetic and sensitive manner. I am actively involved in audits, and publications to maintain good medical practice alongside the tough demands of clinical work. This requires refinement of my time management and organizational skills. I believe in sharing the skills and experiences, which I do by not only involving myself in teaching but also in charity and voluntary work. I possess qualities of a good team leader and an effective team player, which I have gained thr ough my clinical and non-clinical experiences. I prioritize work and this helps me in coping when working under pressure. I am making most of the opportunities to gain experience and refine my personal skills and will do my best to become a good ophthalmologist. Injuries in Sports and Exercise | Case Studies Injuries in Sports and Exercise | Case Studies PDG. Understanding Injury in Sport and Exercise Settings Self-Selected Case Studies Introduction In this case study we shall consider three athletes who are superficially similar and have presented with injuries as a result of their sport. The athletes will be referred to as Mr.A, Mr. B and Mr. C. Each is in their twenties and are club standard runners. Mr.A fell during a training run and sustained an inversion injury to his left ankle. Mr. B presented with a pre-patella bursitis of his right knee and Mr. C could not compete because of severe metatarsalgia. Mechanism and pathophysiology of injury If we consider the aetiology and mechanisms of each injury we can see that although they are largely sports related and, to a degree sports specific, each is fundamentally different in terms of presentation, cause, treatment and outcome. Let us consider Mr. A. who fell during training. He was a modest club runner who ran sporadically for personal enjoyment. He sustained an acute inversion injury which resulted in a partial tear of the lateral malleolar ligament. This ligament effectively joins the Tibia to the talus and calcareous and is largely responsible for the lateral stability of the joint. (Clemente C D 1975). There was immediate pain and subcutaneous swelling and, although he could weight bear immediately after the injury, Mr.A could only walk with great pain. Lateral distortion of the joint was extremely painful. The fundamental aetiology of the injury was a sudden inversion stress to the ankle which was greater than the ligament could withstand and this resulted in rupture of some of the collagen fibres of the lateral ligament together with the underlying joint capsule. This allowed substantial bleeding to track into the surrounding tissues which, together with both extravasation of synovial fluid and accum ulation of tissue oedema, led to the clinically apparent swelling over the lateral malleolus. Mr. B, by contrast, was a fiercely competitive sub-elite runner who noticed his injury developing more slowly over a period of about ten days. He was preparing for a race and had increased his running schedule both in intensity and distance covered. Initially he was aware of a discomfort in the anterior aspect of his knee which felt superficial. This was apparent at the end of his training sessions and persisted for a few hours while travelling home. As the training sessions intensified, the pain grew more persistent until it occurred throughout his running session. Although it was a nuisance, it was not severe. By the end of ten days it had become very severe to the point that there was demonstrable swelling over the lower pole of the patella which was tender to the touch and constantly painful. The mechanism of this injury is typical of the overuse injury seen with overtraining. It is believed to arise initially from micro tears within the body of the patella ligament which become inflamed and the constant stresses involved with training do not let the injury heal sufficiently and the inflammation becomes accumulative to the point that histology would show inflammatory changes occurring throughout the ligament and this, in turn, causes friction on the surrounding structures. (Hewett T E et al. 1999) This is manifest as a constant progressively painful swelling localised in the region of the patella ligament and is aggravated by movement of the knee joint. It is tender to the touch and limits exercise. Mr. C was a club runner of modest ability, but with an over optimistic appreciation of his own ability, who trained with the elite runners at the club. He frequently complained of minor injuries that were blamed for his particular lack of performance in races. On this occasion he presented with pains in his forefoot over the metatarsal heads which was very specific and occurred when the toes were flexed but not when they were extended (an unphysiological finding). He could run, but complained bitterly of forefoot pain after the race and could be seen hobbling off the track and around the changing rooms after the race. Examination of his foot was completely unremarkable and no consistent physical abnormality could be found. It was noticeable that Mr. C vociferously blamed this problem for his inability to perform well. No physical diagnosis was made but the aetiology of his complaint was thought to be a psychosomatic manifestation of his anxiety relating to his inability to beat the b etter runners at the club. This equated to a mechanism of cognitive distortion and denial together with a compensatory conversion symptom complex to rationalise his poor performance. (Patel D R et al. 2000) In short we see three competitive runners with common presentations of injury, but three very different mechanisms of pathophysiology and aetiology. Each will require a different approach to treatment and will follow a very different illness trajectory. Psychology of sports injury There are a number of different theoretical concepts (with differing degrees of security of evidence base) that can be usefully employed in describing sporting motivation and are therefore relevant to the incidence of sporting injury. (Wigfield A et al. 2000) The literature on these subjects is very extensive and beyond the scope of this essay to consider in any degree of detail. Reversal theory (Apter M J 2001) is commonly utilised in this regard and can describe relationships between the personality characteristics and motivational stimuli. Paratelic dominant athletes commonly enter the paratelic motivational state and are typically arousal seekers and engage in high risk and highly competitive sports (viz Mr. B )(Cogan N A et al. 1998) Mr.A, by contrast is the typical telic dominant athlete who tend to be arousal avoiders, who plan and consider their training carefully and prefer low intensity experiences. (Kerr J H et al. 1999) Let us start this consideration of the psychology of sports injury with an assessment of Mr. C who presents with a primarily psychological complaint Mr. C has an overtly psychosomatic presentation. This can be conveniently described in terms of reversal theory (Apter M J 2001). and the paratelic concept (Murgatroyd S et al. 1978). There are aspects of the metamotivational states described in the theory which are relevant to Mr. C’s perception of his motives for continued participation in running even when he was clearly failing to achieve his set targets. If appears that Mr. C has developed a variation of a paratelic protective framework with somatic constructs. He needs the high arousal gratification of the paratelic dominant athlete by lining up on the starting line with the elite athletes, but has developed his idiosyncratic phenomenological frame as a coping mechanism which allows him a sensation of safety from his perception of failure with a series of somatic excuses for his failure to perform. (Kerr J H 2001) One psychological technique that has been demonstrated to work in this type of case is a form of cognitive behaviour therapy which allows a realisation of the implications of an action to be re-evaluated by the client. (Fowler D et al. 1995) This was combined with a strategy of the setting of â€Å"step-by-step† short term goals. This effectively allowed the client to consider his need to unrealistically compare himself with the elite athletes and to allow him to achieve progressive attainable targets, thereby recognising and capitalising on achievement rather than ruminating on poor past performance comparisons with other (better) athletes. (Pain M et al. 2004). The idea is that by setting and achieving some short term goals, the client can focus on the present, make small progressive steps, and recognise new achievements, instead of ruminating on past performance level. (Hall H K et al. 2001). Complicity by the clinician in agreeing that his symptoms may actually be physical can be completely counterproductive in this type of case (see on) Injury management The object of management of any injury is clearly to maximise the degree of recovery possible and to limit and residual disability that may occur as a result of the injury. In broad terms we can consider the immediate (first aid) treatment and the subsequent longer term management as separate issues. (Hergenroeder A C 2003) In the case of Mr.A’s acute injury the essential elements of treatment (once the diagnosis has been confidently made) should be to prevent further tissue damage and bleeding by immobilisation of the joint (splinting), prompt cooling to reduce the tissue reaction to the injury, analgesia to relieve the pain (but with the caveat that pain relief should not be an indication to stress the joint) and pressure to minimise blood and tissue fluid accumulation. The longer term considerations should be that weight bearing should be kept to a minimum for about 7-10 days. Mobilisation should then begin in a graded fashion over about four to six weeks. Running on flat surfaces could realistically begin (possibly with an ankle support) after that time. Mobilisation (both active and passive) is necessary to ensure that the fibroblastic activity of the ligament repair mechanism does not restrict movement of the joint to the degree that the long term restriction of movement becomes a problem. (Orchard J 2003) Mr.A would be well advised to avoid running on uneven surfaces for a period of many months and to undertake a course of physiotherapy involving modalities such as wobble board training to improve his proprioceptive capabilities. (Lephart S M et al. 1997) Because of the injury, Mr.A should always regard himself as more prone to get a recurrence if he were to have another fall. Mr. B should be treated in a distinctly different way. There is no â€Å"acute† first aid treatment as such, as the critical factor here is to recognise that the injury is the result of overuse of a joint. Rest, or in some cases simply a reduction in the training schedule, is often all that is needed to allow the condition to resolve. (Krivickas L S 1997) There is some evidence to suggest that the use of NSAIAs may help to reduce the inflammatory reaction and thereby increase the speed of recovery but their use must be undertaken with caution because of the propensity of runners to consider that the analgesic properties of the NSAIA group can be equated with evidence of suppression of the pathophysiology of the lesion, and therefore they can start to increase their training schedule thinking that the inflammation has settled because the knee is pain free. (Nickander R et al. 2005) Some clinicians would recommend the use of steroid injections in the paratendon tissues. It has to be noted that this is contentious because of the risk of tendon damage if the steroid is injected into the wrong area. Mr. C requires no immediate physical treatment. Indeed on an intuitive basis, physical treatment could be considered counterproductive as it could be viewed as reinforcing his aberrant adaptive and compensatory mechanisms by colluding in the physical nature of his pathology. By entrenching his position, the clinician could be actually aggravating the problem. Once confidently diagnosed, Mr. C should be promptly referred to a competent sports psychologist for treatment along the lines that we have outlined above. Lecture to club The first serious examination of sports injuries as a specific entity was carried out by William Haddon in 1962 (Haddon W et al. 1962). The growth in interest since then has been exponential. In terms of general observation about sports related injuries we can observe that it is generally accepted that one of the common predictive factors for an injury is a history of previous injury. (Watson A W 2001) ( Lee A J et al. 2001) Various studies have reported increased odds ranging from 1.6 to 9.4. (Chalmers D J 2002). In order to accommodate this information it is clearly important to know the other risk factors involved The practical problem is that in order to assemble a coherent evidence base on this issue it is vital to have well designed and robust trials to consider. In short, there are very few of these. (Parkkari J et al. 2001). A critical analysis of the literature on the subject reveals that there is a surprising paucity of evidence for any significant preventative measure for sports injury. Part of the reason for this is that if there is anecdotal evidence that a procedure reduces the risk of injury then it is likely that a substantial proportion of participants will already be using it. This makes double blind trials almost impossible. Van Mechelen ran a trial of the prophylactic value of warming up and down only to find that over 90% of participants were using the technique already. (van Mechelen et al. 1993) It is clearly of dubious ethical possibility, quite apart from a practical possibility to get a control group of athletes not to warm up just to see if they are more likely to get injured. The management of sports injuries is therefore largely a combination of intuition based on anatomical and physiological principles, guided by experience and validated by what scientific evidence base there is on the subject. The three case studies presented above have all occurred in similar status club runners for completely different reasons. This therefore exemplifies the need to undertake a holistic assessment of each case in order to be in a position to make a confident and accurate diagnosis. One should note that there are occasions when the injury or the pathology is blindingly obvious, but it is more common to have to undertake further investigations in order to firmly establish the diagnosis. Mr.A might require X-Rays to exclude a chip fracture of his lateral malleolus. Mr. B might require some blood tests to exclude a connective tissue disorder and Mr. C may need further assessment in order to be confident that there is no genuine physical pathology.

Cultural Literacy Essay

Cultural Literacy. What is it? How can one define it? Is it knowing the answers to questions such as: who are Joseph Stalin and Frederick Douglass? Who fought in WWI? What was the Louisiana purchase? What is the second commandment? Name an amendment to the constitution? Try this on for size, who is the host of Total Request Live on MTV? Who is J. Lo engaged to? Cultural literacy is knowledge of what one should know in order to be a functional member of an educated society. It includes an understanding of one’s language, grammar, pronunciations, syntax in speech, and the basic listening, reading and writing skills along with the knowledge of mathematics and history. Many argue whether cultural literacy is possible or not, whether it can truly exist. The whole concept of cultural literacy is an important one. Especially to America. America, being the great melting pot that it is needs to have this for everybody. We are constantly receiving new people into our country and as they come, our cultures â€Å"rub off† on each other, they begin to intertwine with another. By understanding these different groups we understand their cultures and we become more culturally literate (to the other persons culture) and our cultures actually mix. America is great because of this. The concept of cultural literacy is an important one to understand in order to make America a better place to live for everybody. To answer the question of whether or not it is possible for cultural literacy to exist, we need to break it down. We have to know what it means and who it applies to. We also need to understand how it works. The works of E. D. Hirsch, Jr. , â€Å"Cultural Literacy (excerpt),† and Jay Chaskes, â€Å"The First-year Student as Immigrant,† expose the definition of what cultural literacy is and how this definition varies as it comes across various cultures, groups, members and individuals in a society. Cultural literacy is possessing the information needed to be able to interpret a statement the way it was meant to be interpreted by an author or speaker. Many things are open to different interpretations, though. Hirsch agrees, â€Å"? we cannot treat reading and writing as empty skills, independent of specific knowledge. The reading skill of a person may vary greatly from task to task. The level of literacy exhibited in each task depends on the relevant background information that person possesses (217). † People who give this information are tryingto pass along a message. As long as one can receive that message correctly in most cases, they are considered culturally literate. We can safely assume that everyone is at a different level of cultural literacy since everyone knows a different amount and has experienced a different amount. A good author or speaker is able to communicate his or her message to these people with different amounts of knowledge and experience and have the same viewers receive the basically same message. One may be considered â€Å"culturally literate† somewhere, then culturally illiterate elsewhere. You can’t expect anyone to know all the information needed to interpret something correctly. But with what they already know, they can form a correct conclusion. Jay Chaskes, the author of â€Å"The First-Year Student as Immigrant,† supports this notion: As with all newly-arrived immigrants, students must learn various skills and acquire certain knowledge bases before the can be recognized as citizens of their adopted country (i. e. , they must successfully complete their first year of college). These skills and knowledge bases include communication skills, cultural rules and expectations, geography, performing as a â€Å"good citizen,† and learning the community’s services and structure. (Chaskes 31) When students and immigrants first arrive they have some sense of knowledge and understanding of where they are and what is around them. Once they begin to adapt to their new environment and learn new skills to be seen as a member of their community, they become more culturally aware of their surroundings. With the knowledge they had and with the new information they attained the students and immigrants form â€Å"correct conclusions and assumptions. † People have different levels of cultural literacy based upon experience and common knowledge. For example lets take a closer look at Chaskes’ section on Professors and Academic Culture: Compared to their high school teachers, college professors may present a more aloof and distant demeanor. The student discovers that the rhythm of the professor’s work day may limit when he or she might be seen. The comings and goings of the professoriate seem somewhat inscrutable. (32) This culture of new first-year students are not used to this. They might be used to a closer relationship with their professors like in their secondary school where they are able to reach and meet with their professors at specific hours. Everything is different now. It is not that the system of their previous school was wrong,it is just different. But once they become accustomed, they acculturate to this new college culture. Because of their previous experience, they were on a different level of cultural literacy. Basically different cultures are going to see things differently than another. Neither is wrong it is just how one culture interprets that specific thing. Some people might be more educated in one area and others in another. Basic knowledge may be held by someone who have gone through many experiences, and because of their experiences they could understand what another is talking about. A different, well educated person might not get the idea as well because it is harder for them to relate. For example, in Hirsch’s excerpt, â€Å"Cultural Literacy,† he exhibits an experiment conducted by Richard C. Anderson and others at the Center for the Study of Reading at the University of Illinois in which they grouped two sets of paired readers. These individuals were all similar in sexual balance, educational background, age, and social class. However, the only discrepancy was that one group was in India and the other in the U. S. : Both were given the same two letters to read. The texts were similar in overall length, word-frequency distribution, sentence length and complexity, and number of explicit propositions. Both letters were on the same topic, a wedding, but one described an Indian wedding, the other an American wedding. The reading performances of the two ? split along national lines. The Indians performed well in reading about the Indian wedding but poorly in reading about the American one, and the Americans did the opposite. This experiment not only reconfirmed the dependence of reading skill on cultural literacy, it also demonstrated its national character. (Hirsch 220) This is a great example by Hirsch that demonstrates what actually happens in the real world. The fact that the Indian was knowledgeable about the Indian wedding is not surprising since he probably attended one. So, to the Indian culture he is probably considered culturally literate. If the American had previously attended an Indian wedding he would definitely know more about such an event. He would be building upon his â€Å"Indian cultural literacy† by experience, which doesn’t apply to IQ (or fact knowledge). An equal example of how this would occur in the real world would be an Indian person who just immigrated to America. Let’s assume he can speak English already, but he has no previous experience in America. If he read about the wedding of the president he could probably understand the basics, but not the specifics. The reason for that is because India has weddings and so he will understand how two people are joined together. If he had never heard of that he would probably be thinking what they mean by joining together. But assuming he understands that part of it, he might not understand that rings are usually what spouses give each other at weddings, or that, traditionally, Americans are making a vow to God when they get married. Although the wedding has two different meanings to two different people of different cultures, both ideas are still correct—like someone saying toe-may-toe, vs. toe-mah-toe. It is just how it is interpreted from that individual’s culture and experiences. Since culture is the way certain people live, and everyone lives in different ways, no one can have the same cultural literacy. So even if we all posses the same knowledge, our differences in personal experiences set our levels of cultural literacy apart. One thing can mean something different to two people, but may be correct either way. It is just how that certain thing is deciphered by every culture. Also, in one place a person could be considered culturally literate, and in another he or she would be considered culturally illiterate (even if they were more knowledgeable than most people in their own culture). If they had time to adapt to the new culture and gain experience in that culture, then they would become more and more â€Å"culturally literate† in that culture.

Milk & Food Coloring Lab Report (Importance of Surfactant)

Importance of Surfactant Introduction Surfactant is an essential component for the respiratory system to function properly. Knowing the physiology of surfactant in the alveoli is important to know when learning the structure of the air sacs and how they work. This experiment is designed to make the understanding of surfactant in the alveolar film easier to learn, because it's not very simple. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the walls of the alveoli. Surfactant is produced to reduce the surface tension of the water molecules that primarily compose the walls of the alveoli.For this experiment, we will be using milk and food coloring to represent the water (milk) and gas (food coloring) in the respiratory system, as seen in the liquid-gas boundary of the alveolar wall (water) and its volume (gas). We will place the milk in a shallow dish so that it completely covers the bottom of the dish. Drops of food coloring are going to be added in to the milk at the center of the dish, and then observed. Drops of liquid dishwashing soap, representing surfactant, are then added to the center as well. Once the soap drops are added we will observe what changes happen to the food coloring and milk.Because I know milk is non-polar and food coloring is polar, my hypothesis predicts the two will not mix voluntarily at first, but the soap acting as a surfactant, when added, will help the two liquids mix together. Materials and Methods For this experiment, I used a 16oz milk, 4 different color food coloring bottles, liquid hand soap, and a small clear dish with approximately 5 inches in diameter. I placed the dish in a flat steady surface. I then poured the milk making sure the whole bottom of the dish is covered and still remained shallow.Next, I added about four drops of food coloring to the milk at the center of the dish. Lastly, I added about four drops of the liquid hand soap in the same exact place where I had added the food col oring. Results When the food coloring was added into the milk, there was no reaction. The food coloring did not mix into the milk, it just sat there clumped together like oil in a lava lamp. After adding the drops of liquid soap, the food coloring droplets rapidly mixed into the milk by running in every direction. It looked like an explosion of color.The color streaks continuously span slowly in the milk. Discussion As my hypothesis stated, the milk and food coloring did not mix voluntarily because of their polarity. Non-polar molecules want to bond with other non-polar molecules (London dispersion forces) and polar molecules bond with the polar molecules (Dipole-Dipole forces). Think of all the milk molecules acting as very powerful magnets between each other, and the same with the water molecules. In this case, the soap –acting as the surfactant- broke the surface tension between the two liquids allowing them to mix together.In other words, it reduced the magnetic attractio n between them. As we stated, the milk molecules are non-polar and the food coloring molecules are polar. Soap is one of the awesome liquids that is both polar and non-polar. Its molecules have a polar head, which attracts other polar molecules, and a non-polar body, which attracts other non-polar molecules. When the liquid soap molecules were added to the solution, they attracted both the milk and food coloring molecules causing them to mix like they did.In the alveoli, the gas is non-polar and the water in the walls of the alveoli is polar. Surface tension in the alveoli is very high because of the liquid/gas boundary. This surface tension draws the liquid molecules closer together and reduces their contact with the gas molecules; this way the alveoli do not collapse. The water in the walls of the alveoli help the alveolar walls come together during exhalation (when the oxygen leaves the alveoli), so that they stick together and allow the alveoli to reach their smallest size.The s urfactant that is secreted aids the walls to be able to come together, but not with the attraction of their potential because it’s too strong. If they came together with their normal attraction, the walls would stick together and their strong surface tension would not allow them to unstick. A collapsed alveola will have to be completely re-inflated during each inspiration, which takes a lot of energy to do. With the surfactant, during inhalation the incoming gas is able to split the walls open because their attraction is not as strong.This way, the walls are able to come apart easier and make more space for the oxygen that fills up the alveoli. If our alveolar cells did not produce surfactant whatsoever, breathing would be very hard. Each inhalation would not have the easy flow it has now; it would take a lot of energy and not to mention be tougher. Conclusion Just like the water and gas in our lungs, the milk and food coloring would not have been able to mix. Both the liquid soap and the surfactant reduce the magnetic force that unites liquid molecules- in this case allowing milk and food coloring to mix.Without this experiment, we’d be overlooking one of the many underrated ways our bodies get away with remedies for making our daily routines easier. This experiment helps us understand the importance of surfactant in the respiratory system. Liquid molecules have a very high surface tension that is not easy to get rid of. But, as we observed, savvy Mother Nature blessed us with surfactant and soap that can easily break bonds. Literature Cited Marieb, Elaine N. , and Katja Hoehn. Human Anatomy ; Physiology. 9th ed.

Hamstring Injury Sport - Free Essay Example

Sample details Pages: 11 Words: 3324 Downloads: 9 Date added: 2017/06/26 Category Medicine Essay Type Research paper Did you like this example? Latest Concepts in Hamstring Rehabilitation and Injury Prevention Hamstring injuries can be frustrating injuries. The symptoms are typically persistent and chronic. The healing can be slow and there is a high rate or exacerbation of the original injury (Petersen J et al. Don’t waste time! Our writers will create an original "Hamstring Injury Sport" essay for you Create order 2005). The classical hamstring injury is most commonly found in athletes who indulge in sports that involve jumping or explosive sprinting (Garrett W E Jr. 1996) but also have a disproportionately high prevalence in activities such as water skiing and dancing (Askling C et al. 2002). A brief overview of the literature on the subject shows that the majority of the epidemiological studies in this area have been done in the high-risk areas of Australian and English professional football teams. Various studies have put the incidence of hamstring strain injuries at 12 16% of all injuries in these groups (Hawkins R D et al. 2001). Part of the reason for this intense scrutiny of the football teams is not only the high incidence of the injury, which therefore make for ease of study, but also the economic implications of the injury. Some studies (viz. Woods C et al. 2004) recording the fact that hamstring injuries have been noted at a rate of 5-6 injuries per club per season res ulting in an average loss of 15 -21 matches per season. In terms of assessing the impact of one hamstring injury, this equates to an average figure of 18 days off playing and about 3.5 matches missed. It should be noted that this is an average figure and individuals may need several months for a complete recovery. (Orchard J et al. 2002). The re-injury rate for this group is believed to be in the region of 12 31% (Sherry M A et al. 2004). The literature is notable for its lack of randomised prospective studies of treatment modalities and therefore the evidence base for treatment is not particularly secure. If one considers the contribution of the literature to the evidence base on this subject, one is forced to admit that there is a considerable difficulty in terms of comparison of various differences in terminology and classification. Despite these difficulties this essay will take an overview of the subject. Classification of injuries To a large extent, the treatment offered will depend on a number of factors, not least of which is the classification of the injury. In broad terms, hamstring injuries can have direct or indirect causation. The direct forms are typically caused by contact sports and comprise contusions and lacerations whereas the indirect variety of injury is a strain which can be either complete or incomplete. This latter group comprises the vast majority of the clinical injuries seen (Clanton T O et al. 1998). The most extreme form of strain is the muscle rupture which is most commonly seen as an avulsion injury from the ischial tuberosity. Drezner reports that this type of injury is particularly common in water skiers and can either be at the level of the insertion (where it is considered a totally soft tissue injury) or it may detach a sliver of bone from the ischial tuberosity (Drezner J A 2003). Strains are best considered to fall along a spectrum of severity which ranges from a mild muscle cramp to complete rupture, and it includes discrete entities such as partial strain injury and delayed onset muscle soreness (Verrall G M et al. 2001). One has to note that it is, in part, this overlap of terminology which hampers attempts at stratification and comparison of clinical work (Connell D A 2004). Woods reports that the commonest site of muscle strain is the musculotendinous junction of the biceps femoris (Woods C et al. 2004). In their exemplary (but now rather old) survey of the treatment options of hamstring injuries, Kujala et al. suggest that hamstring strains can usefully be categorised in terms of severity thus: Mild strain/contusion (first degree): A tear of a few muscle fibres with minor swelling and discomfort and with no, or only minimal, loss of strength and restriction of movements. Moderate strain/contusion (second degree): A greater degree of damage to muscle with a clear loss of strength. Severe strain/contusion (third degree): A tear extending across the whole cross section of the muscle resulting in a total lack of muscle function. (Kujala U M et al. 1997). There is considerable debate in the literature relating to the place of the MRI scan in the diagnostic process. Many clinicians appear to be confident in their ability to both diagnose and categorise hamstring injuries on the basis of a careful history and clinical examination. The Woods study, for example, showing that only 5% of cases were referred for any sort of diagnostic imaging (Woods C et al. 2004). The comparative Connell study came to the conclusion that ultrasonography was at least as useful as the MRI in terms of diagnosis (this was not the case if it came to pre-operative assessment) and was clearly both easier to obtain and considerably less expensive than the MRI scan (Connell D A 2004). Before one considers the treatment options, it is worth considering both the mechanism of injury and the various aetiological factors that are relevant to the injury, as these considerations have considerable bearing on the treatment and to a grea ter extent, the preventative measures that can be invoked. It appears to be a common factor in papers considering the mechanisms of causation of hamstring injuries that the anatomical deployment of the muscle is a significant factor. It is one of a small group of muscles which functions over two major joints (biarticular muscle) and is therefore influenced by the functional movement at both of these joints. It is a functional flexor at the knee and an extensor of the hip. The problems appear to arise because in the excessive stresses experienced in sport, the movement of flexion of the hip is usually accompanied by flexion of the knee which clearly have opposite effects on the length of the hamstring muscle. Cinematic studies that have been done specifically within football suggest that the majority of hamstring injuries occur during the latter part of the swing phase of the sprinting stride (viz. Arnason A et al. 1996). It is at this phase of the running cycle that the h amstring muscles are required to act by decelerating knee extension with an eccentric contraction and then promptly act concentrically as a hip joint extensor (Askling C et al. 2002). Verrall suggests that it is this dramatic change in function that occurs very quickly indeed during sprinting that renders the hamstring muscle particularly vulnerable to injury (Verrall G M et al. 2001). Consideration of the aetiological factors that are relevant to hamstring injuries is particularly important in formulating a plan to avoid recurrence of the injury. Bahr, in his recent and well-constructed review of risk factors for sports injuries in general, makes several observations with specific regard to hamstring injuries. He makes the practical observation that the older classification of internal (intrinsic) and external (extrinsic) factors is not nearly so useful in clinical practice as the consideration of the distinction between those factors that are modifiable and those tha t are non-modifiable (Bahr R et al. 2003). Bahr reviewed the evidence base for the potential risk factors and found it to be very scanty and â€Å"largely based on theoretical assumptions† (Bahr R et al. 2003 pg 385). He lists the non-modifiable factors as older age and being black or Aboriginal in origin (the latter point reflecting the fact that many of the studies have been based on Australian football). The modifiable factors, which clearly have the greatest import for clinical practice, include an imbalance of strength in the leg muscles with a low H : Q ratio (hamstring to quadriceps ratio) (Clanton T O et al. 1998), hamstring tightness (Witvrouw E et al. 2003), the presence of significant muscle fatigue, (Croisier J L 2004), insufficient time spent during warm-up, (Croisier J L et al. 2002), premature return to sport (Devlin L 2000), and probably the most significant of all, previous injury (Arnason A et al. 2004). This is not a straightforward additive compilation however, as the study by Devlin suggests that there appears to be a threshold for each individual risk factor to become relevant with some (such as a premature return to sport) being far more predicative than others (Devlin L 2000). There is also some debate in the literature relating to the relevance of the degree of flexibility of the hamstring muscle. One can cite the Witvrouw study of Belgian football players where it was found that those players who had significantly less flexibility in their hamstrings were more likely to get a hamstring injury (Witvrouw E et al. 2003). If one now considers the treatment options, an overview of the literature suggests that while there is general agreement on the immediate post-injury treatment (rest, ice, compression, and elevation), there is no real consensus on the rehabilitation aspects. To a large extent this reflects the scarcity of good quality data on this issue. The Sherry Best comparative trial being the only w ell-constructed comparative treatment trial, (Sherry M A et al. 2004) but even this had only 24 athletes randomised to one of two arms of the trial. In essence it compared the effects of static stretching, isolated progressive hamstring resistance, and icing (STST group) with a regime of progressive agility and trunk stabilisation exercises and icing (PATS group). The study analysis is both long and complex but, in essence, it demonstrated that there was no significant difference between the two groups in terms of the time required to return to sport (healing time). The real significant differences were seen in the re-injury rates with the ratio of re-injury (STST : PATS) at two weeks being 6 : 0, and at 1 year it was 7 : 1. In the absence of good quality trials one has to turn to studies like those of Clanton et al. where a treatment regime is derived from theoretical healing times and other papers on the subject. (Clanton T O et al. 1998). This makes for very difficult comparisons, as it cites over 40 papers as authority and these range in evidential level from 1B to level IV. (See appendix). In the absence of more authoritative work one can use this as an illustrative example. Most papers which suggest treatment regimes classify different phases in terms of time elapsed since the injury. This is useful for comparative purposes but it must be understood that these timings will vary with clinical need and the severity of the initial injury. For consistency this discussion will use the regime outlined by Clanton. Phase I (acute): 1–7 days As has already been observed, there appears to be a general consensus that the initial treatment should include rest, ice, compression, and elevation with the intention to control initial intramuscularly haemorrhage, to minimise the subsequent inflammatory reaction and thereby reduce pain levels. (Worrell T W 2004) NSAIAs appear to be almost universally recommended with short term regimes (3 7 days) starting as soon as possible after the initial injury appearing to be the most commonly advised. (Drezner J A 2003). This is interesting as a theoretically optimal regime might suggest that there is merit in delaying the use of NSAIAs for about 48 hrs because of their inhibitory action on the chemotactic mechanisms of the inflammatory cells which are ultimately responsible for tissue repair and re-modelling. (Clanton T O et al. 1998). There does appear to be a general consensus that early mobilisation is beneficial to reduce the formation of adhesions between muscle fibres o r other tissues, with Worrell suggesting that active knee flexion and extension exercises can be of assistance in this respect and should be used in conjunction with ice to minimise further tissue reaction (Worrell T W 2004). Phase II (sub-acute): day 3 to 3 weeks 0 Clanton times the beginning of this phase with the reduction in the clinical signs of inflammation. Goals of this stage are to prevent muscle atrophy and optimise the healing processes. This can be achieved by a graduated programme of concentric strength exercises but should not be started until the patient can manage a full range of pain free movement (Drezner J A 2003). Clanton, Drezner and Worrell all suggest that â€Å"multiple joint angle, sub-maximal isometric contractions† are appropriate as long as they are pain free. If significant pain is encountered then the intensity should be decreased. Clanton and Drezner add that exercises designed to maintain cardiovascular fitness should be encouraged at this time. They suggest â€Å"stationary bike riding, swimming, or other controlled resistance activities.† Phase III (remodelling); 1–6 weeks After the inflammatory phase, the healing muscle undergoes a phase of scar retraction and re-modelling. This leads to the clinically apparent situation of hamstring shortening or loss of flexibility. (Garrett W E Jr. et al. 1989). To minimise this eventuality, Clanton cites the Malliaropoulos study which was a follow up study with an entry cohort of 80 athletes who had sustained hamstring injuries. It was neither randomised nor controlled and the treatment regime was left to the discretion of the clinician in charge. It compared regimes which involved a lot of hamstring stretching (four sessions daily) or less sessions (once daily). In essence the results of the study showed that the athletes who performed the most intensive stretching programme were those who regained range of motion faster and also had a shorter period of rehabilitation. Both these differences were found to be significant. (Malliaropoulos N et al. 2004) Verrall suggests that concentric strengthening fo llowed by eccentric strengthening should begin in this phase. The rationale for this timing being that eccentric contractions tend to exert greater forces on the healing muscle and should therefore be delayed to avoid the danger of a rehabilitation-induced re-injury. (Verrall G M et al. 2001). We note that Verrall cites evidence for this from his prospective (un-randomised) trial Phase IV (functional): 2 weeks to 6 months This phase is aimed at a safe return to non-competitive sport. It is ideally tailored to the individual athlete and the individual sport. No firm rules can therefore be applied. Worrell advocates graduated pain-free running based activities in this phase and suggests that â€Å"Pain-free participation in sports specific activities is the best indicator of readiness to return to play.† (Worrell T W 2004) Drezner adds the comment that return to competitive play before this has been achieved is associated with a high risk of injury recurrence. (Drezner J A 2003) Phase V (return to competition): 3 weeks to 6 months This is the area where there is perhaps the least agreement in the literature. All authorities are agreed that the prime goal is to try to avoid re-injury. Worrell advocates that the emphasis should be on the maintenance of stretching and strengthening exercises (Worrell T W 2004). For the sake of completeness one must consider the place of surgery in hamstring injuries. It must be immediately noted that surgery is only rarely considered as an option, and then only for very specific indications. Indications which the clinician should be alert to are large intramuscular bleeds which lead to intramuscular haematoma formation as these can give rise to excessive intramuscular fibrosis and occasionally myositis ossificans (Croisier J L 2004). The only other situations where surgery is contemplated is a complete tendon rupture or a detachment of a bony fragment from either insertion or origin. As Clanton points out, this type of injury appears to be very rare in football injur ies and is almost exclusively seem in association with water skiing injuries (Clanton T O et al. 1998). It is part of the role of the clinician to give advice on the preventative strategies that are available, particularly in the light of studies which suggest that the re-injury rate is substantial (Askling C et al. 2003). Unfortunately this area has an even less substantial evidence base than the treatment area. For this reason we will present evidence from the two prospective studies done in this area, Hartig and Askling Hartig et al. considered the role of flexibility in the prophylaxis of further injury with a non-randomised comparative trial and demonstrated that increasing hamstring flexibility in a cohort of military recruits halved the number of hamstring injuries that were reported over the following 6 months (Hartig D E et al. 1999). The Askling study was a randomised controlled trial of 30 football players. The intervention group received hamstring streng thening exercises in the ten week pre-season training period. This intervention reduced the number of hamstring injuries by 60% during the following season (Askling C et al. 2003). Although this result achieved statistical significance, it should be noted that it involved a very small entry cohort. Conclusions. Examination of the literature has proved to be a disappointing exercise. It is easy to find papers which give advice at evidence level IV but there are disappointingly few good quality studies in this area which provide a substantive evidence base. Those that have been found have been presented here but it is accepted that a substantial proportion of what has been included in this essay is little more than advice based on theory and clinical experience.
