He decides to decides to use a simple random interview a specified number of sample. Using this method the female and male school pupils, a researcher needs to obtain the name specified number of arts, sciences and of every school in the country. He then sends a students and interviewing them until questionnaire to each of the selected his quota is complete. The researcher would have method only those pupils present at to make sure that he obtained the the same time and in the same place name of every school in the country as the researcher have a chance of for this method to work properly. The researcher wants to find out The researcher is interested in about national detention rates, but is carrying out semi-structured interested also in finding out about interviews with pupils who have been school policy concerning detention. He decides that to do this he needs to However, he finds that the school has visit each selected school. To cut not kept accurate records of these down on travel costs, he decides to pupils. Using this approach the school because he will method, geographical ‘clusters’ are be seen by the pupils as an authority chosen and a random sample of figure attached to the school. He schools from each cluster is decides that a snowball sample would generated using random number be the most appropriate method. He tables found at the back of some happens to know a pupil who has statistics books. Using this method been on detention recently and so the researcher only needs to travel to speaks to her, asking for names of schools within the selected other pupils who might be willing to geographical regions.

This small bursa was to become the theme of his life’s work; and from this theme many side excursions were destined to be taken. Although in subsequent years many other interests took of his time and stamina, nevertheless he pursued the study of the subdeltoid bursa and its environs throughout his entire life, the culmination being a book entitled The Shoulder, which was published in 1934. He pursued these studies with great tenacity; he made and recorded many original observations and became an authority in the new fields. In all his undertakings he worked to capacity; he left no stone unturned, he went deeply into the subject. These traits were first exhibited in 1895 when he was appointed assis- tant in anatomy at the Harvard Medical School. For the next several years he studied in minute detail the subdeltoid bursa and its pathology in the dissecting room and on postmortem specimens. This study made him aware of the clinical signi- Ernest Amory CODMAN ficance of this region of the shoulder joint.

In future purchase antivert 25mg amex medications depression, suc- cessful products will increasingly be tuned to flow with the stream of human physiological function purchase antivert 25 mg overnight delivery treatment kitty colds, even to mimic it in fine detail. Modelling and computation are set to make major contributions, since: • devices become sufficiently ‘intelligent’, with their on-board comput- ing power, to use analytical descriptions of (patho-)physiological organ function; 148 P. Future medical training, diagnosis and – even surgical – treatment will increasingly be performed remotely. Thus, the combination of sophisti- cated sensory devices with advanced micro-manipulation equipment will, together with 3D ‘interactive feedback’ models, provide new tools and approaches for the medical profession. Analytical bio-modelling is also set to make major practical contribu- tions and to transform the way society handles health-related matters. The ‘added benefit’ of in silico technologies for health care includes the following: • New, interactive in silico teaching and educational tools will be avail- able for doctors and the greater public. This will help to improve pro- fessional skills and general health awareness. Future health-related implications of an individual’s behavioural patterns or of various treat- ment strategies can be assessed and compared on the basis of long-term case predictions. The latter will be based on improved access to expert information, statistics, case reports, etc. Medium-term deci- sions will benefit from the early recognition of epidemiological pat- terns, etc. Long-term policies can be based on detailed investigations into the cost-benefit-relation of restorative versus preventative strate- gies which, undoubtedly, will consolidate the case of preventative med- icine. The making of the virtual heart 149 • In silico models will aid both the standardisation and individualisation of medical care. Standardisation of diagnoses, drug and device descrip- tions, procedures, etc. On the other hand, advanced models will allow development of patient-specific procedures for diagnosis and treat- ment. This will move the focus from the treatment of diseases to the curing of patients. Kolston MacKay Institute of Communication and Neuroscience, University of Keele, Sta≈ordshire ST55BG, UK 9. Even when you are sitting still in a quiet room your blood is being pumped to every tissue, your kidneys are filtering body fluids, your immune system is guarding against infection and your senses are continuously monitoring all kinds of information from their surroundings. Scientists are very good at studying single molecules and single cells but the challenge of understand- ing molecular and cellular processes in entire organs or body systems is a daunting one. Their behaviour is controlled by basic laws of physics that can be described by mathematical equations. By solving these equations on com- puters, scientists are able to investigate the operation of complete organs with a flexibility and level of detail that is impossible experimentally. This article shows how computers have already illuminated the work- ings of a variety of biological systems, with a particular emphasis on the operation of the ear. Soon it will be possible to represent in a computer model every single cell contained within a whole organ. These models will lead to a profoundly deeper understanding of how biological organs work, whilst reducing dramatically the need for animal experimentation. Longer term, computer modelling will provide a valuable tool in the design of new, simpler cellular structures that would mimic the known operation of a bio- logical organ to either replace their defective counterparts or to perform 151 152 P. KOLSTON entirely new tasks with efficiencies that are impossible using current tech- nologies. Given the impressive specifications of such organs, these new devices – manufactured in carbon or silicon – could have numerous research, clinical and industrial applications. Cars must both protect the occupants from physical intrusions into the passenger compartment, and minimise the deceleration forces that act upon them. The first of these requirements could be achieved easily by making the car body rigid. Unfortunately, the deceleration forces would then be intolerably large, so instead the design aim is to make those parts of the vehicle that are outside the passenger compartment absorb as much of the impact energy as possible, by making them deform in the pre- defined time-dependent manner that minimizes peak deceleration levels. In the past when car crashworthiness was designed entirely experi- mentally, full-sized prototypes were subjected to the crash scenarios required by the relevant authorities. If the performance was unacceptable, the shape deformations of the components making up the prototype were examined.

The proceedings Many national and most major international conferences will publish proceedings generic 25mg antivert amex symptoms 8 days before period. Should you be presenting a paper as such a conference you will be required to provide your contribution to these proceedings during the conference or shortly afterwards discount antivert 25mg without a prescription symptoms 0f gallbladder problems. It is not appropriate to present the organisers with the script and slides that you have just used in your presentation. The contribution to the proceedings should be written in a style consistent with that used in a journal article. The content should be the same as in the presented paper but not necessarily identical. It is perfectly permissible to expand some areas, particularly with regard to the methods and results sections, where more details could be included. This should, of course, all be done within the guidelines for format and length specified by the organisers. This saying provides a reminder that, however good your preparation for the presentation of the paper has been, there is still plenty that can happen to ruin your carefully laid plans. You should find it useful to work your way through the checklist in Figure 4. Handling questions Most conferences have a fixed period of time for questions. Some people in the audience are going to test you out with penetrating questions and how you handle them will enhance or detract from the impact of your performance. This is one of the reasons why we suggested a full dress rehearsal in front of your department in order to practice your answering of difficult questions for which some participants will be eagerly searching. The following are some points to remember: Listen to the question very carefully. If the question is complex or if you suspect that not all the audience heard it, restate it clearly and succinctly. Avoid the danger of using the question to give what amounts to a second paper. Be alert to questioners who are deliberately trying to trick you or to use the occasion to display their own knowledge of the subject. If the question is particularly awkward or aggressive try to deflect it as best you can. Strategies include agreeing with as much of what was said as possible, acknowledging legitimate differences of opinion or interpretation, or suggesting you meet the questioner afterwards to clarify your position. However, do not be afraid to politely disagree with any questioners, however eminent, when you are sure of your ground. You will find that the poster has several advantages over the traditional paper such as: Allowing readers to consider material at their own rate. Enabling participants to engage in more detailed discussion with the presenter than is the case with the usually rushed paper discussion session. If the conference organisers have arranged a poster session we suggest that you consider taking advantage of it. It may provide you with an opportunity to present additional material to the conference that would otherwise be difficult because of limitations on the number of speakers. A conference poster is a means of presenting information from a static display. A poster should include a least the following parts: A title An abstract Text and diagrams Name of author(s), their address(es) and where they may be contacted during the conference. Additional material that you might consider for the poster, or in support of the poster, includes: Illustrations and photographs Exhibits and objects Audio-visual displays, such as a video A take-away handout, which might be a printed reduction of your poster. A blank pad, so that when you are not in attendance interested readers can leave comments or contact addresses for follow-up. Firstly, ascertain from the conference organisers the facilities and size of space that will be available. The poster should commu- nicate your message as simply as possible, so do not allow it to become clogged with too much detail. Layout ideas can be gleaned by looking through newspapers and magazines or, better still, from graphic design books and journals.
