Older adults' exercise behavior: roles of selected constructs of social-cognitive theory

Exercise is consistently related to physical and psychological health benefits in older adults. Bandura's social-cognitive theory (SCT) is one theoretical perspective on understanding and predicting exercise behavior. Thus, the authors examined whether three SCT variables-self-efficacy, self-regulation, and outcome-expectancy value-predicted older adults' (N = 98) exercise behavior. Bivariate analyses revealed that regular exercise was associated with being male, White, and married; having higher income, education, and self-efficacy; using self-regulation skills; and having favorable outcome-expectancy values (p < .05). In a simultaneous multivariate model, however, self-regulation (p = .0097) was the only variable independently associated with regular exercise. Thus, exercise interventions targeting older adults should include components aimed at increasing the use of self-regulation strategies.     

Challenges and Recommendations to Enforcement of Alcohol Policies on College Campuses: An Administrator's Perspective

Abstract

Objective: The purpose of this study was to examine challenges and recommendations (identified by college administrators) to enforcing alcohol policies implemented at colleges in the southeastern United States. Methods: Telephone interviews were conducted with 71 individuals at 21 institutions. Results: Common challenges included inconsistent enforcement, mixed messages received by students, and students’ attitudes toward alcohol use. The most common recommendations were ensuring a comprehensive approach, collaboration with members of the community, and enhanced alcohol education.     

What's an Oscar worth?

This article examines the impact of an Academy Award nomination and award for best picture, best actor/actress, and best supporting actor/actress on a film's (i) market share of theaters, (ii) average revenue per screen, and (iii) its probability of survival. The model is estimated using weekly box-office data for a matched sample of nominated and non-nominated films. The results indicate substantial financial benefits for a nomination and award for best picture and best actor/actress. The structure of rewards is consistent with that found in two-stage, single-elimination tournaments.     

Is bounded-vision an adequate explanation of strategic decision-making failures

One important area in which Management Science should be involved must surely be in the prevention of corporate failure. In this paper we therefore use a scientific methodology to try to identify the major causes of such failure. Two widely differing systems are examined and a large number of hypotheses considered as explanations of failure. In each case the only hypothesis which we are unable to reject, is that prior to the failure the dominant decision-makers in the system were not prepared to accept facts which were plainly available and which, if acted upon, could have prevented disaster. This allows us to suggest some ways of helping to prevent failure. Nevertheless, we feel that research into the mechanisms generating this phenomenon, which we have called bounded-vision, is required before adequate technologies can be designed.     

Formative evaluation of a motivational intervention for increasing physical activity in underserved youth

The present study was designed to develop an innovative motivational intervention (based on Self-Determination Theory and Social Cognitive Theory) to increase physical activity (PA) in underserved adolescents. Sixty-four adolescents (35 females, 29 males; 50% minority; 65% on reduced lunch program; ages 11-13 yr) participated in either an 8-week motivational intervention after-school (n = 32) or a typical after-school program (n = 32). The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Formative evaluation data was collected by staff through daily forms throughout the 8-week program and through observational data completed by independent objective observers during 2 weeks of the program. The major themes that were identified addressed theoretical concepts regarding the intervention and logistical issues in delivering the intervention. The data revealed information regarding the importance of the cognitive appropriateness of the PA and motivational activities, the environmental climate for promoting nurturing relationships, developing specific strategies for increasing intrinsic rather than extrinsic reinforcement, and developing methods for preventing social "cliques" and gender conflicts to maintain an appropriate level of support in the social climate. Themes for training staff included focusing on team building, leadership, and nurturing. This formative evaluation is being used to formalize a randomized trial to test the effects of a student-centered motivational intervention on increasing PA in underserved 6th graders.
