Eating habits and stress correlates in a female student population

Interviews were conducted with 100 female undergraduate students to investigate the relationship between anxiety, work related stress and abnormal eating habits. Dietary habits were examined using the EAT-26 questionnaire and an anorexia check list (derived from the DSM classification for anorexia nervosa). Anxiety and stress were assessed using self report questionnaires and blood leukocyte counts. Dietary restraint was associated with anxiety, irritability and psychosomatic complaints. Additionally, subjects with high EAT-26 scores tended to have low leukocyte counts. A six month follow-up study, carried out prior to examinations, showed a decrease in leukocyte counts, an increase in mean weight and an increase in abnormal eating habits.     

Measuring multimodality

Existing sample statistics do little to address the question of multimodality, a question which is interesting in itself and which also arises in exploratory multivariate data analysis using projection pursuit. We propose a new index more strongly geared to the specific task of measuring multimodality than other sample statistics known to us, we show how to compute it, explore its properties, and consider its generalisation to the multivariate case. The behaviour of the index is illustrated by some simple numerical examples.     

EIS—A guide for executives

Although the use of executive information systems (EIS) is increasing, many senior executives have such mixed feelings about them that there is an ‘EIS paradox’. Information managers and software suppliers believe this is because senior executives are intimidated by information technology, but this does not hold up to scrunity. The EIS paradox occurs because of failure to explain coherently how EIS fit with other aspects of the organizational database and what EIS can and cannot do for a senior executive and his or her organization. This article is designed to close the ‘information gap’ about EIS specifically for senior executives. The change in terminology from ‘data processing’ to ‘information technology’ is symptomatic of a change in the way in which computers are used. Rather than being the mere province of the data professional, information technology as exemplified by EIS can be applied to tasks where judgement and selectivity are required. The crucial point about EIS is, however, that computing can complement and increase managerial qualities of imagination and intelligence but not replace them.     

A model of nonverbal exchange in physician-patient expectations for patient involvement

This paper reviews the literature on the nonverbal aspects of physician-patient interaction, focusing on how expectations about patient involvement are conveyed and negotiated by physicians and patients. Important outcomes of this process, such as satisfaction, adherence, and patient health, are examined. A model of physician-patient negotiation involving four interaction styles is presented to examine the negotiation process and the effects of patient involvement on outcomes.We would like to thank Valerian Derlega and the two reviewers, Debra L. Roter and Richard L. Street, for their helpful comments.     

Refinements of Nash Equilibrium: A critique

Rational play of Noncooperative Games is investigated under the assumptions that a particular form of Best Reply Principle holds, each player has at least one rational strategy and all strategies are either rational or irrational. These assumptions are shown to imply that (a) some weakly dominated strategies are rational (b) recursive reasoning can be misleading (c) only a Strict Nash Equilibrium can be a solution. A Supplementary Best Reply Principle is formulated. It sheds further light on which games have solutions and on rational play in games without them. The relationship between these results and those of other authors is discussed.     

Double machine operation and psychological strain

This study examines the effects of double machine operation on psychological strain. CNC drilling machine operators' reactions to their job were monitored as they rotated between three different work conditions; single machine operation, double machine operation, and double machine operation with additionally high responsibility for products. Results show no effect of double machine operation on strain where responsibility was low. Double machine operation under the condition of high responsibility, however, was found to increase strain.     

Checkered Expectations: Predictors of Approval of Opening a Casino in the Niagara Community

This paper reports on the findings of a survey prior to the opening of a casino in Niagara Falls, Ontario (N= 1002 adults) on approval of the casino, expectations regarding the impact of the casino, attitudes toward gambling, gambling behaviour, and demographic information. The respondents generally had a positive attitude towards gambling. The expectations of community impact clustered into 3 factors: negative social consequences (crimes, addiction), negative environmental consequences (litter, noise, traffic), and positive economic consequences (jobs, stores, income). The majority of respondents expected economic benefits from the casino as well as a decrease in the environmental quality of the city. Expectations regarding social problems were mixed with a majority expecting an increase in serious crimes, but only a minority expecting an increase in people on welfare. Covariance structure modelling revealed that a positive attitude towards gambling and expecting economic benefits were positively related to approval of the casino, and expecting social problems was negatively related to approval. Given that more than seven in ten respondents supported the opening of the casino, the expected economic benefits coupled with a generally positive attitude towards gambling, apparently outweighed concerns about problems associated with gambling.
