Role ambiguity and volunteer board member performance in nonprofit sport organizations

We explore the relationship between multidimensional role ambiguity and individual board member performance within nonprofit voluntary sport organizations. Role ambiguity accounted for 29 percent of the variance in perceived board member performance, and ambiguity about one's responsibilities was the strongest predictor. These findings extend our understanding of the drivers of individual board member performance within voluntary sport organizations and the multidimensional nature of role ambiguity. The study supports previous arguments that knowing what to do is fundamental to one's performance, and more critical than knowing how to do it, and what difference it makes.

Examining the Absence of a Gender Effect on Abortion Attitudes: Is There Really No Difference?

Earlier research on attitudes toward abortion has found little or no difference between men and women. To the limited extent that there is any gender effect, men are slightly more inclined than women to be prochoice (e.g., Cook, Jelen, and Wilcox 1992). Women, however, have been found to regard the issue as more important (Scott and Schuman 1988). The present study uses General Social Survey data from 1972 through 1994 to further explore gender and attitudes toward abortion. We find that within three marital statuses–single, married, widowed–men are somewhat more supportive of abortion rights but that women consider the issue to be more important and have clearer but not necessarily stronger attitudes than men. When differences in workforce participation are controlled, the sex effect is reversed, with women being more prochoice than men. Although significantly related to abortion attitudes, race, marital status, and religious identity are not relevant to this reversal in the sex effect.     

A testing approach to estimation

Results from the theory of uniformly most powerful invariant tests are used to develop a new parameter estimation procedure. The procedure is used to derive parameter estimators for several important distributions. Results of simulation studies comparing the performances of the new estimators and maximum likelihood estimators are presented.     

Reactions of leaders to 360-degree feedback from subordinates and peers

The current study examined factors related to leaders' reactions to 360-degree feedback. The total sample consisted of 220 supervising managers from a large public utility. We collected data in three waves which involved pretest, performance rating, and posttest surveys (49 leaders had valid data from all three waves of measurement). We hypothesized that overall ratings, organizational support, and perceived rater ability would be positively related to four reaction criteria (acceptance and perceived usefulness of subordinate feedback and peer feedback). Results showed that overall ratings were related to acceptance of peer and subordinate feedback, but were less consistently related to perceptions of feedback usefulness. For perceived usefulness of subordinate feedback, organizational support accounted for unique variance beyond overall ratings, and perceived rater ability was marginally significant. None of the predictions for perceived usefulness of peer feedback were significant. The authors discuss limitations, implications, and suggestions for future research.     

Peer Estimates of School-Aged Boys' and Girls'Aggression to Same- and Cross-Sex Targets

Research comparing boys' and girls' aggression has typically focused on the overall amount of aggression using a within-sex design. Less attention has been given to differences in children's aggression according to the sex of the target. In the research reported here, boys' and girls' amount and style of aggression were compared for same- and cross-sex targets. A peer estimation procedure was used with children in Grades 2, 6, 9, and 11. Physical, verbal, and indirect aggression were studied. Although there were some differences according to Grade level, both the amount and style of aggression for boys and for girls differed as a function of the sex of target, with cross-sex aggression generally falling between the amount and style of boys -to-boys and girls-to-girls aggression. The results draw attention to the possible separate nature of the cross-sex context, and highlight the importance of taking into account the target of aggression when investigating differences in aggression between boys and girls.     

On the inferential use of predictive sample reuse

The predicitive sample reuse (PSR) data analysis technique proposed by Geisser and Eddy (1979) is applied to the analysis of categorical data. This application yiclds a new approach which has a number of advantages over classical methods for analysis of such data. A PSR technique for comparing linear or nonlinar regressino relationships, for two or more populations, and a PSR ailernative to certain nonparaemetri statistical tesis are also proposed.     

Protecting Children and Young People from Tobacco‐Related Harm: A Review

Tobacco use continues to be a serious public health issue. Although declining in middle‐ to high‐income countries, smoking rates are often higher in disadvantaged communities and vulnerable groups. Knowledge about tobacco‐related harm also tends to be incomplete. To date, legislation has focused on public domains, but the pressure to protect children in the home and other private spaces is fast becoming a focal point for potential legislation and intervention. Negotiating the boundary between privacy and protection is likely to become a matter of professional concern.     

Dividing to keep muscle together: the role of satellite cells in aging skeletal muscle

The factors responsible for the atrophy of skeletal muscle with aging remain to be elucidated. Recent evidence points toward an important role for a population of cells located on the surface of skeletal muscle fibers, known as satellite cells, in maintaining the integrity of skeletal myocytes throughout the life span. This Perspective examines the role that these cells are thought to play in aging muscle atrophy, and highlights a recent study by Brack and colleagues that attempts to understand the role of satellite cells in maintaining the ratio of myonuclear number to cytoplasmic volume within myocytes as we age.
