Use a combination of Stick rigorously to a sampling procedures if it is sampling technique that is appropriate for your work. Admit your mistakes, learn by them and change to something more appropriate HOW TO CHOOSE YOUR PARTICIPANTS / 53 as your sample to overcome this problem. If you’re inter- ested in large-scale quantitative research, statistical meth- ods can be used to choose the size of sample required for a given level of accuracy and the ability to make general- isations. These methods and procedures are described in the statistics books listed at the end of this chapter. If your research requires the use of purposive sampling techniques, it may be difficult to specify at the beginning of your research how many people you intend to contact. Instead you continue using your chosen procedure such as snowballing or theoretical sampling until a ‘saturation point’ is reached. This was a term used by Glaser and Strauss (1967) to describe that time of your research when you really do think that everything is complete and that you’re not obtaining any new information by continuing. In your written report you can then describe your sam- pling procedure, including a description of how many people were contacted. SUMMARY X If it is not possible to contact everyone in the research population, researchers select a number of people to contact. X There are two main types of sampling category – prob- ability samples and purposive samples. X In probability samples, all people within the research population have a specifiable chance of being selected. Only within random samples do participants have an equal chance of being selected. X The size of sample will depend upon the type and pur- pose of the research. X Remember that with postal surveys it might be difficult to control and know who has filled in a questionnaire. X In some purposive samples it is difficult to specify at the beginning of the research how many people will be contacted. X It is possible to use a mixture of sampling techniques within one project which may help to overcome some of the disadvantages found within different procedures. This is a document which sets out your ideas in an easily accessible way. Even if you have not been asked specifically to produce a research proposal by your boss or tutor, it is a good idea to do so, as it helps you to focus your ideas and provides a useful document for you to reference, should your research wander off track a little. Before you start work on your research proposal, find out whether you’re required to produce the document in a specific format. For college and university students, you might be given a general outline and a guide as to how many pages to produce.

This arbitrary classification was clearly based on judgements about which therapies were more popular (with patients and doctors) and were 146 THE CRISIS OF MODERN MEDICINE more established in terms of training and procedures of professional regulation cheap cialis extra dosage 200mg online erectile dysfunction watermelon. There was no attempt to make any objective claim for the superiority of buy cialis extra dosage 60 mg cheap erectile dysfunction treatment homeopathy, say homeopathy and herbalism over rolfing and iridiology. The BMA’s main concern was to foster the profes- sionalisation of the big five complementary therapies and to marginalise the rest. The price paid by the medical profession for this opportunist approach towards alternative therapies was to betray the historic commitment to medical science which had been the foundation of its growing success over two centuries. It is quite understandable that patients who find conventional medicine ineffective and conventional medical practitioners unsympathetic should turn to alternative practitioners. But for orthodox doctors to collaborate with such practitioners implies a capitulation to irrationalism. Nor can the legitimacy of alternative therapeutic systems be enhanced by studies in the form of clinical trials which claim to show their effectiveness. No doubt many patients derive much therapeutic benefit from praying to statues and icons, but this is no reason why these techniques should be incorporated into clinical practice. In his commentary on the nineteenth century triumph of medical science over the antecedents of today’s alternative therapies, Dalrymple observed that the distinctive feature of scientific medicine was its openness to critical evaluation, revision and improvement, features it shared with the wider Enlightenment traditions of reason and progress from which it emerged (Dalrymple 1998:58). By contrast, rival approaches— such as Samuel Hahnemann’s ‘intellectually ridiculous’ homeopathy — offered no comparable method of development, but were presented as ‘complete, fully-formed’ systems. The correspondence between the inquisitive and interventionist outlook of medical science and the dynamic and progressive values of Victorian Britain was the key to the early success of the medical profession. Dumbing down In Tomorrow’s Doctors, the GMC outlined the ‘goals and objectives’ of the new curriculum under the rubric of ‘knowledge, skills and attitudes’ (GMC 1993). Whereas in the past knowledge was crammed for exams, skills were picked up on the job, and attitudes (for better or for worse) unconsciously assimilated, now students were going to be taught formally in all three areas. Knowledge would be reduced to a ‘factual quantum’ defined by a ‘core 147 THE CRISIS OF MODERN MEDICINE curriculum’: this would include the familiar basic medical sciences, but also unfamiliar subjects such as ‘human relationships’ and ‘the importance of communication’. The extensive and detailed attitudinal objectives reflected the values of the culture of therapy and the demands of political correctness (neither previously a major influence on the medical mainstream). Students would be expected to show respect for patients’ diverse identities and rights, they should be able to ‘cope with uncertainty’ and they should display an ‘awareness of personal limitations, a willingness to seek help when necessary and an ability to work effectively as a member of a team’. One of the key concepts of the new curriculum is that of ‘prob- lem-based’ learning: instead of acquiring a grounding in basic medical sciences before encountering sick patients, students begin from a clinical problem presented by a patient and organise their studies around this problem (Lowry 1993:28–32). The idea is that, by being relevant to the resolution of a real clinical problem, their study of anatomy, physiology, biochemistry, etc. The role of the teacher is no longer to transmit knowledge, but to facilitate the process of problem-solving by students, working collectively, in teams. The defect of problem-based learning is that it assumes that defining a clinical problem is a straightforward matter, whereas in practice it is often profoundly difficult. According to Abraham Flexner, whose historic 1910 report promoted the reorganisation of medical education in the USA on the basis of scientific medicine, ‘for the analysis of the simplest situation which the ailing body presents, considerable knowledge is required’ (Flexner 1925:13) Furthermore, for practical treatment ‘still another volume of knowledge and experience is requisite’. Flexner explicitly rejected the method of proceeding on ‘superficial or empirical lines’ which is what is implied by the notion of the ‘relevance’ of scientific inquiries to the problem that has been identified. It is a commonplace that what appears to be relevant or important to the untrained eye is revealed by science to be merely a manifestation of some underlying phenomenon. Indeed, if what appears to be relevant coincided with what is actually important, then there would be no need for science. Flexner offered a definition of science as the ‘persistent effort of men to purify, extend and organise their knowledge of the world in which they live’ (Flexner 1925:3). He particularly emphasised the word ‘effort’, insisting that students should ‘strive to transcend native powers, prejudices, limitations’.

But the limit of our potency may be reached rather quickly when an illness strikes generic cialis extra dosage 50 mg free shipping erectile dysfunction gene therapy treatment. As we’ve already discussed discount cialis extra dosage 60mg on line medication that causes erectile dysfunction, the illusion of control shatters and we have to come to 226 Living with Your Mystery Malady terms with being powerless. There are forces greater than we are, and we need to let go of the notion that if we simply try hard enough, are smart enough, or are good enough, we can overcome them. Although it may be possible to do so, relief may come in its own time rather than ours. This is especially true when we don’t even know what our malady is and have great doubts about ever resolving it. Like recovering alcoholics who, as a prelude to staying sober, must admit that they’re powerless over alcohol, you can benefit greatly by acknowledging your lack of power over your medical condition. Try to remember that control over your condi- tion was only an illusion anyway, and the sooner you can accept this, the more peace of mind you will find. Letting go of the need to control can actually free up more energy for your diagnostic detective work and allow you to take more compassionate care of yourself. Stop the Guilt and Blame As we described earlier, one of our most self-destructive attitudes is feeling guilty or blaming ourselves or others. You certainly didn’t choose to have this malady, and your family and friends would probably love nothing more for you than to see you healthy and well. Feeling guilty takes too much time and energy—neither of which you can afford to waste. Here’s how to look at it, and what you might do to avoid these feelings. Perhaps you can’t cook dinner, do someone’s laundry, chauf- feur the kids around, go to work, play golf or tennis, or give a party. In fact, there may be many things you are unable to do, but no matter what shape you are in, you can always give someone your attention, a kind word, a lov- ing look, a shoulder to cry on, or a sympathetic ear. If you have a partner, you might feel guilty that you’re too sick to have the “intimacy” you once enjoyed and presume that intimacy must mean sex. Touching and looking deeply into your loved one’s eyes can be as inti- mate as sexual intercourse. Conversely, making love even when you might not be able to do much else for your loved one can be nurturing for both of you. Understanding Your Feelings About Being Sick 227 Paying attention to your children and listening to everything about their soccer game even when—or especially when—you couldn’t drive them or be there for the game is nurturing for you and them. Telling them a story with your eyes closed, lying on your bed with them next to you, is certainly a means of loving them. Expressing your love in every way you are able can be enough, more than enough. In a world where everyone seems too busy, giving someone even just a little time and attention can be meaningful. Calling friends or family to remember their birthdays or some event that may be happening in their lives can help you maintain those relation- ships even if you can’t go to lunch, a shopping mall, a football game, or the weekly card game. E-mailing a joke and letting friends know you thought of them can be a means of loving them.
