Modem notions of medical authority being essentially embodied in the figure of the professionally trained and registered practitioner and his corporate representatives, and in the medical textbook or official pharmacopoeia, are comparatively recent developments. Much work has been done by historians of medicine to show that, far from being merely an underdeveloped version of modem medicine, the...

The untimely death of Mrs. Norman, for the past 25 years Senior Psychologist in the Department of Psychological Medicine, Guy's Hospital, which took place in August after a very short Alness, has deprived the N.A.M.H. of a valued friend and helper. *or many years she served on our Committee on Psychologists and her Department at Guy's regularly received a student for training under her. In addi...

This paper outlines a new approach to determining the effect of part complexity on the cost of manufacturing a composite part. It also describes a methodology for predicting cost based on complexity that uses the techniques of Method Time Measurement (MTM). The proposed methodology offers a relatively simple method to predict the fabrication time of a complex component. It is based on the theor...

Count data obtained in developmental toxicity-teratogenicity studies, such as the number of fetal deaths or the number of malformed fetuses per litter, are routinely analyzed by univariate statistical methods. Such methods ignore the dependence among the different outcomes that are measured in the study. Tests of significance based upon the individual outcomes may lead to incorrect conclusions ...

he electrochemical control of oxidation and reduction processes in organic and inorganic systems is an area of extensive research in both academia and industry. Electrochemical techniques are extremely useful in generating interesting species in unusual oxidation states, or for producing reactive intermediates (as, for example in the reductive dimerization of vinyl cyanide in the Monsanto manuf...

thoughtfully, with good taste and, for the most part, with meticulous accuracy. In several passages, however, words and sentences are incorrectly translated (see for example, Nos. 13, 85, and 216, pp. 42, 100, and 210-212, respectively). A few titles of subdivisions, moreover, have been ignored or overlooked as in No. 95, p. 108, where a new paragraph should read: Dentifrices: 'The white dentif...

Crawford and his colleagues describe an analysis of frog species in El Cope, Panama. “We discovered that 30 species were lost, including five undescribed species, representing 41 per cent of total amphibian lineage diversity in El Cope. The irony of increased species discovery coupled with enigmatic population declines in amphibians was recognised at least 10 years ago, “yet until now we have l...
