Life, survival, and behavioral health in small closed communities: 10 years of studying isolated Antarctic groups.

In the late 1980s the Australian Antarctic Division collaborated with NASA to use the Australian National Antarctic Research Expeditions' (ANARE) stations to pursue research of benefit to both programs. This article outlines the data collection efforts, the development of analyses, and selected results, and describes some of the benefits for the aerospace, health, and environmental psychology communities. The Behavior and Performance Laboratory at Johnson Space Center developed a questionnaire to sample broadly the many aspects of life in extreme environments analogous to space missions.

Gender differences in leader and follower perceptions of social support in Antarctica.

The purpose of this study was to methodologically explore the links among social support, gender, age, prior experience, leader/follower status, and leadership effectiveness noted in previous accounts from Antarctic stations. Data for this study were collected from volunteers involved in Australian National Antarctic Research Expeditions conducted from 1996 to 2001. Multilevel analysis revealed that most of the variance in perceptions of social support was at the individual level (71%).

Team climate at Antarctic research stations 1996-2000: leadership matters.

Introduction: The popular assumption is that extreme environments induce a climate of hostility, incompatibility, and tension by intensifying differences and disagreements among team members. Team members' perceptions of team climate are likely to change over time in an extreme environment, and thus team climate should be considered as a dynamic outcome variable resulting from multiple factors. In order to explore team climate as a dynamic outcome, we explored whether variables at multiple levels of analysis contributed to team climate over time for teams living and working in Antarctica.

Evaluation of an upper extremity student-role functioning scale using item response theory.

Millions of workers suffer from upper extremity (musculoskeletal) disorders. Many of these workers are predisposed to upper extremity musculoskeletal disorders because of early exposure to ergonomic risks as students. Computer usage for four or more hours remains the greatest risk for upper extremity musculoskeletal disorders for workers and students alike.
