Within the interpretive para- found that the health professionals in his study digm medicine 6 year order retrovir 300mg with visa, clinical reasoning may be viewed as a human did not calculate medical decisions but articulated activity that is socially treatment 3 degree heart block buy generic retrovir 300 mg on-line, historically and cultu- arguments in order to persuade patients symptoms 9 days before period buy retrovir from india, collea- rally constructed. Inter- reasoning as used in practice as opposed to their pretive researchers have sought to study indivi- espoused theory (Argyris & Schon? 1974) such as duals within the context of their practice, thereby might be revealed with questions based on a illuminating factors that individuals consider in hypothetical situation (Eraut 2005). An important contribution of interpretive Our review of the history of clinical reasoning has approaches to the study of clinical reasoning has thus far largely considered the history of clinical been in revealing clinical reasoning as a complex, reasoning research as related to medicine. As health multidimensional, integrated, task- and context- professions other than medicine have sought to dependent process. Researchers in fields such as understand the nature of their clinical practice and medicine have traditionally taken narrow perspec- reasoning there has been an increasing use of inter- tives to understanding decision making and clini- pretive research approaches. The use of these cal reasoning; seeking to identify the cognitive approaches has steadily increased since the early process used by expert decision makers. Norman 1980s when Benner conducted seminal work into (2005), in a review of clinical reasoning literature the nature of nursing expertise (Benner 1984)and in medicine, challenged this assumption, suggest- later Gillette & Mattingly (1987) conducted a large ing that there may not be a single representation of scale ethnographic study of reasoning in occupa- clinical reasoning expertise or a single correct way tional therapy. These studies one marvels at the complex and multidimensional were followed by others that used interpretive components of knowledge and skill that she or he approaches. However, much of this research has brings to bear on the problem, and the amazing continued to focus on these same discipline areas adaptability she or he must possess to achieve (e.

A critical approach should be Our interpretation of this situation is that we are able to identify the difference between insights in a time of paradigm shift as described by Kuhn that are genuinely useful and those that are (1996). Some findings of cognitivism, such as the restricted to the philosophical assumptions of a use of hypothetico-deductive reasoning with unfa- particular field.

There is no common measure: in biology the situation is differ- ent from that found in atomic physics medicine names order generic retrovir online. Similarly medicine quetiapine purchase cheap retrovir on-line, if these transmutations are not observed in chemistry medicine you can give cats generic retrovir 300mg otc, it is because the energies used are too feeble. This phenomenon gives up an energy about 3500 times feebler than resulting from the nuclido-biological reac- tion that joins an oxygen atom to a sodium atom! Conclusion the evidence that I have presented (graphically represented in the diagram below) shows clearly that we are in the presence of a hitherto unknown property of matter: biological transmutation, a 42 Biological Transmutation phenomenon that is completely different from the atomic fusions or fssions of physics. Na + + O H K Mg + + H O Ca As a result, all sciences will face a thorough-going re- examina- tion. I sincerely hope that this paper will be suffcient to stimulate the reconsideration of much that is dogmatically adhered to in those sciences today. Appendix Transmutation by Herman Aihara Biological Transmutation Biologically speaking, sunlight, water, air, and elements trans- form into organic matter in the form of carbohydrates, protein, and fat. Man eats vegetables, digested to the simpler form of molecules such as glucose, amino acids, and lactic acid. This theory does not explain why O2 combines with hemoglobin in the red cells instead of the plasma that surrounds it. Because plasma contains more sodium (Na) than red cells, plasma is more yang than red cells. For O to combine with2 hemoglobin, which is inside the red cells, instead of combining with the plasma, the yin-yang difference between plasma and O must be2 smaller than that between O and red cells. In other words, the red cell is another form of plasma after O and hemoglobin (which is produced2 in the liver) have been added to it. Louis Kervran) Plasma (yang) is produced in the intestines from the foods (yin) we eat after the food has digested and combines with bile (yang). This plasma enters the blood vessels through the intestinal villi and starts circulating throughout the whole body. As the O is taken out of the red cells through tissue activity, the2 red cells eventually become yang. These white cells then pass through the walls of the blood vessels and are attracted to yin protein. Biological Transmutations by Hubert Descamps (after professor Kervran) the following questions and answers occurred at a conference held on June 20, 1970 conducted by M. Hubert Descamps at the Centre Ignoramus of Belgium, recorded and transcribed by J. Be- cause the cereal that provokes the most lime, that is the one that re- calcifes the least, but that will give calcium under the form of rough- age. Thus, when one must recalcify an individual, it is necessary to give him magnesium or silicon. Wheat especially is a product that contains silicon abundantly (65 to 68% in the ashes). Consequently, I insist one more time on the necessity of eating whole wheat bread, and true whole wheat bread. A Mac- robiotic knows that to eat cereals is the best system for staying in equilibrium, and you will fnd in them the scientifc proof furnished by Prof. Rice is a little less rich in minerals, but it also contains all the minerals and less waste than the other products. One should always make a difference between a food intended for a curative period and a food 46 Biological Transmutations 47 designed for a normal period. In this last case, the rice goes into our metabolism, but it is not, I believe, a cereal absolutely necessary for us because we live in a region that produces cereals in which we can fnd the elements absolutely necessary. However, when one eats too much wheat, one risks having a little more waste than with rice. It is, therefore, absolutely necessary, in a curative period, to utilize the cereal that gives the least purines possible, and which is the most balanced, which is the case with rice.
