To test validity of cocitation studies as representations of intellectual structure, five-six years of aggregate cocitation data for 41 authors in macroeconomics and 49 authors in genetics of fruit flies were compared with independent judgments of interauthor similarity collected from 14 macroeconomists and 15 geneticists via a card-sorting…

Applies Kuhn's model of the structure of scientific revolutions, Popper's hypothetic-deductive model of science, and Lakatos' methodology of competing research programs to a historical biological episode. Suggests using Kuhn's model (emphasizing the nonrational basis of science) and Popper's model (emphasizing the rational basis of science) in…

Background information, experimental approach, materials needed, procedures used, and typical results obtained are provided for genetic engineering experiments. The course in which these experiments are performed is also described. (JN)

Describes the use of a Pac-Man model (called a Pactype) in teaching various genetics concepts. Indicates that students can learn to make predictions, analyze patterns of inheritance, and evaluate hypotheses before being introduced to the genetics vocabulary. (JN)

Discusses genetic screening in the employment context, which involves identification of individuals hypersusceptible to toxins in the work environment. Examines the status of genetic screening devices against standard testing and legal criteria. (LLL)

Holtzman Inkblot Technique (HIT) responses of 36 same sex and 29 opposite sex college student twin pairs are analyzed. The results are discussed in terms of comparable genetic determination studies with Rorschach responses and the necessity for separate male and female norms on several HIT score response scales. (Author/DEP)

Presents pro and con comments with regards to 1975 APA presidential address under the heading of biological versus social evolution. Other comments are subsumed under the headings of the genetic basis of behavior-especially of altruism, and the value of tradition. (Author/AM)

Presents pro and con comments with regards to 1975 APA presidential address under the heading of the value of traditions. Other comments are subsumed under the headings of biological versus social evolution, and the genetic basis of behavior especially of altruism. (Author/AM)

Notes that most of those who criticized the authors' 1975 APA presidential address seem to explicitly or implicitly share the belief that issues discussed are important areas of study on which divergent perspectives should be developed and discussed even where the best available evidence falls far short of dependable scientific fact. (Author/AM)

Presented is the case history of a severely mentally retarded patient with a 49, XXXXY chromosome pattern. (DB)

Presented is a review of the history of the discovery of gene function, and description of the research and scientists responsible for each major step in the sequence of discoveries. A brief review of the current status of the research is included. (SL)

There are substantial clues that patient behavior with regard to disease treatment and prevention is a partial derivative of the quality of the patient-doctor relationship. Evidence is presented that suggests physicians and nurses are more directive regarding genetic counseling than are health professionals in the counseling field. (LBH)

The ability to negotiate and resolve socioscientific issues has been posited as integral components of scientific literacy. Although philosophers and science educators have argued that socioscientific issues inherently involve moral and ethical considerations, the ultimate arbiters of morality are individual decision-makers. This study explored…

This publication discusses the many different ways medicines work in the body and how this information guides the hunt for drugs of the future. The science of pharmacology--understanding the basics of how our bodies react to medicines and how medicines affect our bodies--is already a vital part of 21st-century research. Pharmacology is a broad…

The booklet describes the STAGES (Swine Testing and Genetic Evaluation System) program developed at Purdue University (Indiana), along with the USDA, National Pork Producers Council and swine breed associations. By selecting breeding stock from a coded catalogue developed by STAGES, producers are able to select the best breeding stock for more…
