Human Adaptation to Isolated and Confined Environments

A study was conducted over seven months in a winter Antarctic isolated and confined environment (ICE). Physiological and psychological data was collected several times a week. Information was collected on a monthly basis on behavior and the use of physical facilities. Adaptation and information indicated that there was a significant decrease in epinephrine and norepinephrine during the middle trimester of the winter. No vital changes were found for blood pressure. Self reports of hostility and anxiety show a linear increase. There were no significant changes in depression during ICE. The physiological and psychological data do not move in a synchronous fashion over time. The data also suggest that both ambient qualities of an ICE and discrete social environmental events, such as the arrival of the summer crew, have an impact on the outcome measures used. It may be most appropiate to develop a model for ICE's that incorporates not only global chronic stressors common to all ICE's but also the role of discrete environmental effects which can minimize or enhance the influence of more chronic stressors. Behavioral adjustment information highlight the importance of developing schedules which balance work and recreational activities

Transdisciplinary Collaboration as a Basis for Enhancing the Science and Prevention of Substance Use and ?Abuse?

Transdisciplinary scientific collaborations (TDSCs) have the potential to strengthen substance use and misuse research and prevention. Despite its growing prominence as a mode for scientific research, research on TDSC remains in a nascent form and its value to the field of substance use and misuse merits further exploration. The overarching purpose of this article is to examine the potential contributions of transdisciplinary science to research and prevention using conceptualizations, methods, and evidence from a case study of two university-based research centers. The article provides (a) a discussion of the societal context and historical developments that have prompted increasing interest in TDSC; (b) a definition and conceptualization of TDSC; (c) a methodological approach for studying TDSC; (d) initial findings from the case study that reflect instances of transdisciplinary intellectual integration and it examines implications of these methods and findings for future research and policy development relevant to substance use and misuse

Enhancing corporate compliance with worksite safety and health legislation

Introduction: A 2-year prospective study evaluated the effectiveness of a managerial training program to enhance corporate compliance with statewide worksite safety and health regulations. The program offered participants information about regulatory requirements and emphasized organizational and environmental strategies for reducing occupational injuries and illnesses. Objectives: To assess the effects of a train-the-trainer program on business managers' knowledge of statewide occupational safety and health legislation and on levels of corporate compliance with regulatory requirements. Methods: Forty-eight small- and medium-sized companies participated in the training sessions during the first year of the study. These firms were compared with 46 control companies that did not receive the training until the conclusion of the study. Results: Participation in the program was associated with higher levels of corporate regulatory compliance 12 months after the training sessions were held (controlling for baseline levels of corporate compliance with the regulations). Program effects on compliance levels were mediated by posttraining changes in managers' knowledge of regulatory requirements. Conclusions: The REACH OUT training program raised managers' awareness of and corporate compliance with statewide worksite safety and health regulations. Impact on Industry: Smaller companies face greater challenges than larger ones in developing and maintaining worksite safety and health programs. Barriers to regulatory compliance, especially in small- and medium-size companies, should be identified and removed to enhance the efficacy of these programs. © 2001 National Safety Council and Elsevier Science Ltd
