A program for studies of altered sleep-wake schedules and performance

Studies of the effects of variations in sleep-wake schedules on human performance tend to run for several days and involve extensive repeated testing in order to take into account time-of-day and cumulative cross-day effects (Broughton & Ogilvie, 1992; Monk, 1991; Webb, 1982). Such research typically addresses issues pertaining to sustained operations and shift work and is often more appropriately conducted in the field. The present paper describes a computer-automated system designed to administer sleep-wake schedules and performance tests, and to store results of such testing in file formats that are easy to access with commercially available statistical packages.     

PRESIDENTIAL ADDRESS

This article reviews policy issues involved in maternity leave or parental leave. Findings from the Wisconsin Maternity Leave and Health Project, a longitudinal interview study of 570 women and 550 of their husbands/partners, are discussed, focusing especially on the issues of maternity leave and women's mental health, and fathers' patterns of taking parental leave. I stress the importance of empirical research if feminist psychologists are to have an impact on public policy.     

Assessment of Knowledge Gains in Proactive Training for Postvention

This paper describes the development of a knowledge measure for the evaluation of a proactive training program for suicide postvention and analyses of its psychometric properties. The 25-item true–false knowledge test was administered before and after each of 12 training sessions; a total of 205 school personnel participated in the training and evaluation. Participants showed significant improvement in overall test scores and on several individual items following the training. Analyses suggested that the measure has construct validity, and that it taps a single underlying dimension. Strengths and weaknesses of the measure, and measurement issues in program evaluation are discussed.     

VOICE MATTERS: BUFFERING THE IMPACT OF A NEGATIVE CLIMATE FOR WOMEN IN SCIENCE

The current study examined whether women scientists' perceptions of voice moderate the impact of poor workplace climates on job satisfaction and whether effective leadership and mentoring promote women's voice. Survey data were collected from 135 faculty women in the natural sciences. The results from multiple regression analyses indicated that negative (e.g., sexist, hostile) departmental climates were related to lower job satisfaction. However, voice interacted with climate, such that women who perceived that they had more voice in departmental matters showed higher levels of job satisfaction than those who perceived having less voice. An additional regression indicated that mentoring by other women (but not men) in academia and effective departmental leadership were positively related to women's sense of voice. Theoretical and practical implications for the retention and success of women in male-dominated fields are discussed.
