A leaderless approach to a minister's peer-support group

This article describes a support group for ministers that uses a leaderless approach. The group has met for over ten years and as a result of that experience has developed in ways that make it unique. These group characteristics are described and are offered as a general guide for ministers as well as members of other helping professions who are interested in peer support.     

The effects of gormone manipulations on aggressive target-biting in mice

Aggressive biting of an inanimate target by mice was studied. Males attacked the bite-target more frequently than females, but this difference disappeared after castration when the response rate of the males approached that of the females. Ovariectomizing the females had little effect on their bite-attack frequencies. Subsequent androgen injections restored the biting-attack frequency of the castrated males to preoperative levels but had little effect on the intact males. Estrogen had little effect on the response frequency of the females, whereas androgen produced a slight increase in their bite-attack frequency. Results indicate that androgen is critical for the maintenance of this aggressive response and that the single subject paradigm utilized in this study was a sensitive measure of aggressive tendencies in mice.     

Identification With All Humanity: The role of self‐definition and self‐investment

Identification With All Humanity (IWAH) relates to higher levels of concern and supportive behavior toward the disadvantaged, stronger endorsement of human rights, and stronger responses in favor of global harmony. So far, IWAH has been conceptualized as a one‐dimensional construct describing the degree with which one identifies with all humans as a superordinate ingroup. However, recent group identification models suggest a multi‐dimensional model to provide a more differentiated approach toward the understanding of the highest level of social identification. Using principal axis (Study 1) and confirmatory (Study 2) factor analyses, we suggest that IWAH sub‐divides into two dimensions—global self‐definition and global self‐investment. Study 2 revealed that global self‐investment was a stronger predictor for both convergent measures (e.g., social dominance orientation and authoritarianism) and behavioral intentions than global self‐definition. Finally, in Study 3, we manipulated IWAH to test its causal effect on donation behavior. Participants in the experimental condition, compared with the control condition, showed higher global self‐investment, which in turn predicted greater giving to global charity. These findings suggest that two dimensions with different behavioral outcomes underlie IWAH.     

Extraversion and job performance: How context relevance and bandwidth specificity create a non-linear,positive, and asymptotic relationship

The personality factor of extraversion has been associated with performance in some occupations (e.g., sales), and it has been one of the most consistent personality predictors of leadership. Recent research indicates that extraversion could have a non-linear relation with performance. At the same time, many researchers have contended that scholars should utilize measures of personality narrower than factors and that the bandwidth and relevance of personality should fit both the criterion and the context of a study. We argue and find that by examining an aspect of extraversion (i.e., social potency) in a particular vocational context (i.e., enterprising job demands), non-linear, asymptotic (diminishing marginal benefits) effects will be demonstrated on a relevant type of performance (i.e., enterprising job performance). We review implications, limitations, and avenues for future research.     

Stalnaker on Mathematical Information

Robert Stalnaker has argued that mathematical information is information about the sentences and expressions of mathematics. I argue that this metalinguistic account is open to a variant of Alonzo Church's translation objection and that Stalnaker's attempt to get around this objection is not successful. If correct, this tells not only against Stalnaker's account of mathematical truths, but against any metalinguistic account of truths that are both necessary and informative.
