A study of data from 12 graduating classes of one medical school showed that medical students' choice to pursue funded medical research was independent of undergraduate major, although slightly more nonscience majors than science majors undertook such research. Concern about increasing nonscience medical school matriculants is seen to be…

Assesses the impact of current coverage and indexing policies on MEDLINE's retrieval performance in the medical behavioral sciences literature by comparing retrievals in EXCERPTA MEDICA, PSYCHINFO, SCISEARCH, and SOCIAL SCISEARCH. Searches were made with descriptors, cited references, and natural language, and recall, precision, and novelty ratios…

Describes the evaluation of four hypertext microcomputer-based software packages for use in a browsing system on a medical or health topic for the South African Medical Research Council exhibit in the South African Museum. Evaluation criteria are explained, and 40 examples of screen displays are included. (four references) (LRW)

Recently, the regression extension of latent class analysis (RLCA) model has received much attention in the field of medical research. The basic RLCA model summarizes shared features of measured multiple indicators as an underlying categorical variable and incorporates the covariate information in modeling both latent class membership and multiple…

In 1976, the Association of American Medical Colleges developed a map-like model to describe the global picture of the U.S. medical school similarities with respect to two loosely defined concepts: an institutional emphasis on research and an emphasis on clinical and graduate medical training. This study is an attempt to replicate the results of…

Responding to a report on the Clinical Research Training Program of the National Institutes of Health, the author finds that the low applicant rate among dental students is due less to lack of interest in the program or its emphasis on research but more to a program structure modeled on a medical school rather than a dental school curriculum.

Describes a study that investigated the use of a natural language processing technique called noun phrasing to determine whether it is a viable technique for medical information retrieval. Evaluates four noun phrase generation tools for their ability to isolate noun phrases from medical journal abstracts, focusing on precision and recall.…

This article presents the author's critique of Anthony F. J. van Raan's article titled, "Measurement of Central Aspects of Scientific Research: Performance, Interdisciplinarity, Structure." van Raan makes an excellent case for using bibliometric data to measure some central aspects of scientific research and to construct indicators of…

A national survey of assistant and associate pharmacy professors (n=491) found differences between disciplines in time allocation, number of publications, and research funding. Time, lack of funding, and need for research assistants were commonly identified as impediments to research productivity. A quantitative method for evaluating productivity…

A study of Norwegian researchers revealed substantially different patterns in age and research productivity in the social sciences, humanities, medicine, and natural sciences. It is suggested that discrepancies arise from differences in the development of scientific disciplines, particularly the speed of knowledge production and technological…

This study of an online search strategy based on word frequency found that it provided 98% sensitivity in retrieving systematic reviews of health-care interventions in MEDLINE, while retaining a low (20%) but acceptable precision. Presents other strategies with other levels of sensitivity and precision and discusses factors that may affect the…

A survey of 244 British university undergraduates in biology, computer science, and English investigated attitudes about various uses of animals, including killing animals to make luxury clothing, killing of animals for food, general and medical research using animals, and captivity. Response differences by discipline, gender, and age were also…

A study investigated the usefulness of instructional materials on the writing of scientific articles by comparing the descriptions of abstracts offered in the textbook with a sample of abstracts drawn from four fields of medicine (clinical medicine, surgery, epidemiology, basic sciences). The comparison was confined to abstracts of results-focused…

Part 2 of a three-part volume for research and development systems researchers, this report attempts to apply the contextual analysis framework of research, development, and innovation (RD & I) activities presented in Part 1. The authors make a detailed analysis of RD & I activities in the sectors of education, civilian aviation, health,…

Health science (epidemiology) is a relatively advanced discipline which offers theories and methods which could be useful in peace science (polemology). Similarities between war and disease, peace and health, center around concern with prevention of physical damage and death on the one hand and preservation and extension of human life on the…
