Can men and women be just friends?

We tested evolution‐based hypotheses about (1) sex differences in perceived benefits and costs of opposite‐sex friendship and (2) differences in perceived benefits of same‐sex friendships and opposite‐sex friendships. In the Preliminary Study (N= 400), an act nomination procedure was used to identify the benefits and costs of same‐sex friendships and opposite‐sex friendships. In Study 1, a total of 231 participants (100 men, 131 women) evaluated the frequency of occurrence of 100 benefits and costs in their closest same‐sex friendship or opposite‐sex friendship. In Study 2, a total of 229 participants (92 men, 137 women) evaluated how beneficial and how costly each would be if it were to occur in their closest same‐sex friendship or opposite‐sex friendship. Results supported several key hypotheses. Men perceived sex with their opposite‐sex friends as more beneficial than did women. Women reported receiving protection from their opposite‐sex friends more often than did men, and they perceived the protection as highly beneficial. Both men and women reported receiving information from opposite‐sex friends about how to attract mates, and they perceived this information as beneficial. The discussion focuses on whether these benefits reflect an evolved psychology of opposite‐sex friendship, or instead are incidental by‐products.     

The Unbiased Mind: A Possible Resource for Medical Problems

The purpose of this pilot study was to explore the problem solving abilities of school‐aged children. The study took place at the summer day camp program at Howard Public School, in Etobicoke, Ontario. There were 15 children (6 boys, 9 girls) with a mean age at the time of testing of 5.1 years. A medical problem with a known solution (concept of a flow‐directed device to determine pulmonary wedge pressure) was presented to 15 children in the form of a children's story. The children were then asked to solve the problem by completing the story. A successful answer was taken to be any that suggested a flow‐directed device. The results showed that of the 15 children who read the story, four suggested flow‐directed methodologies. Other non‐practical, but creative, solutions were suggested. The findings suggest that by translating a previously solved medical problem into a simplistic children's story, preschoolers may provide a conceptual solution.     

Patterns of Preference for Numerical and Verbal Probabilities

We report results of an experiment designed to test a principle formulated by Budescu and Wallsten (1995), that, when communicating uncertainty information, mode choices are sensitive to sources and degrees of vagueness. In addition, we examined subjects’ efficacy in using such uncertainty information as a function of communication mode, source, and vagueness. In phase one of the experiment, subjects in a dyad used precise (numerical) or imprecise (verbal) expressions to communicate to a remote partner precise or vague uncertainty about the likelihoods of events. Spinner outcomes were used to generate precise uncertainty while answers to almanac questions were used to elicit vague uncertainty. In phase two, subjects saw the events paired with their partners’ estimates of similar events, and were asked to gamble on one event from each pair. Communication mode preferences were measured as the relative frequency that subjects chose the numerical mode to either express or receive uncertainty information regarding the events. Efficacy was measured as the relative frequency that subjects choose from the pair the event associated with the objectively more probable uncertainty expression. Underlying uncertainty interacted with direction of communication to affect preferences for modes of expression of the probabilities. Subjects preferred precise (numerical) information, especially for precise events (spinners). For vague events (questions), their preference for precise (numerical) information was stronger when receiving than when communicating information. Similar preferences were reflected in the efficiency of subsequent gamble decisions based on the probability estimates. Specifically, decisions were more efficacious (i.e. consistent with Expected Utility) when degrees of precision in events and estimates matched. © 1997 by John Wiley & Sons, Ltd.     

That He Might Fill All Things: Creation and Christology in Two Treatises by Nicholas of Cusa

Abstract:  Theology in modernity is especially assisted by elements of Christian tradition which work to reunify, after Louis Dupré's formula, the lost synthesis of self, world and God. This article examines the tradition of Christ's immanence in creation, as seen in two short treatises by Nicholas of Cusa from 1445–46. Read together, these treatises illumine Cusa's 'pan-Christic ontology'. The first describes the prospect of 'filiation', the intellect's virtual participation in the Word's sovereignty over created being; the second explains how all beings are lesser theophanies participating in the theophany of God which is the body of Jesus.     

THE RELATIONSHIP BETWEEN PAY-FOR-PERFORMANCE PERCEPTIONS AND PAY SATISFACTION

A study was conducted with 104 hospital employees to assess the relationship between pay-for-performance perceptions and pay satisfaction. Unlike previous research examining this relationship, a multi-item measure of pay-for-performance perceptions and a multidimensional measure of pay satisfaction were used. As hypothesized, the results indicated a positive relationship between pay-for-performance perceptions and pay-raise satisfaction, pay-level satisfaction, and overall pay satisfaction even after the effects of salary level, salary increases, performance ratings, job tenure, job satisfaction, and promotions were controlled. The importance of gathering perceptual data on characteristics of the pay system believed to have differential relationships with the subdimensions of pay satisfaction are discussed.     

SELF‐SACRIFICE TO SAVE THE LIFE OF ANOTHER IN JEWISH AND CHRISTIAN TRADITIONS1

Although both the Jewish and Christian traditions permit and even valorize self‐sacrificial death for the sake of God (martyrdom), and for other people, they diverge on the issue of self‐sacrificial death for the sake of a single individual. The Jewish tradition prohibits such self‐sacrifice on the basis of the principles that (1) God owns the body and that (2) one cannot exchange one's life for another's. Christian ethics, in contrast, permits sacrificing one's life to save a single person based on the model of Christ's self‐sacrificial love. This ethical disagreement exposes a fundamental theological disagreement between the two traditions concerning what constitutes the imago Dei.     

A FIELD STUDY OF PERFORMANCE APPRAISAL PURPOSE: RESEARCH- VERSUS ADMINISTRATIVE- BASED RATINGS

Many researchers have discussed the theoretical and practical importance of rating purpose. Nevertheless, the body of empirical studies, the majority of which were conducted in a laboratory setting, focus on leniency. There has been little research on other effects of rating purpose. The present study examines 223 ratees in a field setting for whom there were both administrative-based performance appraisal ratings (which were actually used for personnel decisions) and research-based performance appraisal ratings (obtained for a validation study). Two of the hypotheses were supported; administrative ratings were more lenient than research-based ratings. The administrative-based ratings demonstrated a statistically significant relationship with ratee seniority, while the research-based ratings did not. There was mixed support for a third hypothesis: Research ratings were significantly correlated with a predictor, while the administrative ratings were not. The difference between the validity coefficients, however, was not significant. Contrary to the hypothesis, the rank order between administrative-based and research-based ratings was relatively high ( r = 33).
