Effects of alcohol on the nonverbal communication of anxiety: The impact of beliefs on nonverbal behavior

Three male and three female raters were shown videotapes of 29 male subjects who were speaking to a silent female confederate. Raters were asked to make 10 judgments about the subjects' behavior. The subjects had been assigned to one of two expectancy conditions in which they were led to believe the drink they consumed prior to meeting the confederate contained alcohol and tonic or tonic only. Actually, half of the subjects in each expectancy condition received alcohol and half received tonic only. Judgments of the female raters viewing the videotapes were congruent with physiological measures of the subjects' anxiety. Those subjects who believed they received alcohol were perceived by female raters as more relaxed, less anxious, less inhibited, and more dominant than subjects who believed they received tonic. The actual content of the drink had no significant effects on the raters' judgements of the subjects' behavior. Male raters were unable to discriminate among the experimental conditions. Implications for possible gender of rater effects in behavioral assessment procedures as well as for the impact of beliefs on nonverbal communication are discussed.     

The making of a hospital physician executive

Physicians are accustomed to having the "buck" stop with them in the clinical arena. Indeed, they resist any attempt to have it otherwise. Management has only recently come back into their consciousness as a career possibility. Management is the "buck" that now belongs to the enemy, represented by managed care, paperwork, and regulation. The thoughts in this article have grown from the author's experience over the past six years as a physician executive in a community hospital, a career that followed 25 years in clinical and anatomical pathology.     

Competitive strategies: a cognitive choice model

A theory of competition between firms in heterogeneous markets is formulated using a psychological model of choice, the heteroscedastic form of the Thurstone random strength model. Market shares are defined in terms of random variables which portray individual variation in perceived utility. The analysis focuses on the relationship between market shares and utility variances. Besides the general theory of competition two special cases are analyzed, each of which can be identified without precise knowledge of the utility parameters. The conclusions tend to support conventional marketing wisdom but emphasize that the degree of dominance of the market leader is a significant factor in its competitive strategy. Short and long-run analyses of the model are presented, and it is shown that the best policy for a particular firm in the short run remains optimal in the presence of competitors' reactions, but it may no longer be effective. The paper concludes with some comments on statistical implementation.     

Race,Sex, and Perception of the Occupational Opportunity Structure among College Students*

Questionnaires were administered to 70 black female, 75 black male, 1,457 white female and 1,429 white male university freshmen. In order to test three alternative theories regarding perceptions of discrimination, analyses of variance related sex, race, and SES to total scores of perceived occupational discrimination against blacks (BDST) and against women (WDST). Blacks perceived significantly more discrimination against black people than did whites; neither sex nor SES differentialed scores on BDST. Black females and white males perceived significantly more discrimination against women than did white females; black females had the highest and white females the lowest WDST scores. A discriminant analysis on white females indicated that high WDST scorers were characterized by an “underdog syndrome” whereas low WDST scorers held internal, individualistic values. The findings indicated the greatest support for the formulation that differential anticipatory socialization into the role of “a person who is discriminated against” characterized white females who perceived more or less discrimination against women.     

Analysis of a complex decision situation — The Simpsons/Simpsons-Sears merger proposal

Many of the decision situations that arise in modern organizations are very complex. Conventional methods of decision analysis have only limited applicability in these situations. This paper describes a method that can be used as an aid to decision making in such situations where interactions between the parties involved are an important factor. The method is illustrated by reference to a recent situation in which there was competition between a number of participants with regard to the future of the firm of Simpsons Ltd of Toronto. The analysis described illustrates the application of a step-by-step procedure that can be used by participants in the analysis of such situations.     

Output planning for material requirements under uncertainty

This paper considers a production planning and control system requiring that, for each work station, a time-phased series of input and output values be estimated. It is assumed that the projected input levels can vary significantly across time periods and that anticipated output levels can be determined by management, subject to limits specified by available manpower and subcontracting. The actual input and output levels for each period depart from the planned levels according to a probability distribution determined empirically. An approach is presented that allows management to evaluate a chosen set of output levels to determine the probability that sufficient amounts of work will be available at a work station each period.
