Angular homeostasis: IV. Polygonal orbits

Some properties are discussed of regular polygons that may result from angular homeostatic processes in stable orbit. To characterize these homeostatic polygons we need to discuss the winding number, the sidedness (integer, fractional and irrational), multiplicity, envelopes, and density. A regular (i.e., equilateral, equiangular) polygon may be closed in one revolution about its unique center, in multiple revolutions, or not at all. A homeostatic polygon can be generated only if all vertices are included in a single polygon, which occurs if and only if the number of vertices and the number of revolutions required to complete the polygon are relatively prime. For the homeostatic polygon to have a finite number of sides (without repeating itself) the angle subtended by any two successive vertices at the center must be a rational multiple of 2. Biological implications of these properties are illustrated.     

Voting at 16? 16–17-Year-Old Germans Vote as Correctly as Adults

Lowering the voting age from 18 to 16 years has recently been a hot topic of the political debate in many democratic countries. This study investigated whether the voting quality of 16–17-year-olds is inferior to that of the voting population. Shortly before the 2021 German federal election, two samples, representative for age and gender, indicated personal preferences about various political issues and weighted them according to importance, allowing for the calculation of individual expected values for political parties. Participants then indicated their voting choice. These choices were normatively correct when individuals voted for the party that best reflected their preferences, that is, the one maximizing the expected value. Results show that the voting decisions of 16–17-year-olds were as good as those by eligible voters. The study indicates that the exclusion of 16–17-year-old Germans in democratic elections cannot be justified by their lack of decision-making ability.     

Développement initial et processus de validation de l’échelle d’auto-efficacité émotionnelle au travail

The study aims to develop and present the validation process of a questionnaire on emotional self-efficacy in the work context from the six steps proposed by Dussault et al. (2007). The study is based on the theories of emotional intelligence of Mayer and Salovey (1997), Petrides and Furham (2001) and the self-efficacy of Bandura (1997). Following an expert analysis and a pre-test, the Emotional Self-Efficacy at Work scale is composed of 41 items. The participants are 985 Canadian workers. The results of confirmatory factor analyzes support the seven-dimensional structure, namely the self-efficiency to perceive one's emotions and those of others at work, the self-efficiency to use emotions at work, the self-efficiency to understand one's emotions and those of others at work and finally, the self-efficiency to manage one's emotions and those of others at work. The results also indicate that the seven dimensions have satisfactory internal coherence indices. The results suggest that this questionnaire is well suited to describe emotional self-efficacy at work. The use of the questionnaire will be discussed.     

Arguers as editors

People use editorial criteria to decide whether to say or to suppress potential arguments. These criteria constitute people's standards as to what effective and appropriate arguments are like, and reflect general interaction goals. A series of empirical investigations has indicated that the standards fall into three classes: those having to do with argument effectiveness, those concerned with personal issues for arguer and target, and those centered on discourse quality. The essay also sketches the affinities certain types of people have for the different criteria.     

The effects of family composition,family health,parenting behavior and environmental stress on children's divorce adjustment

The traditional family composition model of children's divorce adjustment was compared to a family competence model. Subjects included 81 children whose parents remained married, were divorced, or were divorced and subsequently remarried. Divorced families had been separated for between 24 and 48 months. Custodial parents completed questionnaires regarding family functioning, occurrence of stressful life events, and child's psychosocial adjustment. Children completed questionnaires regarding parenting behaviors and self-esteem. A trained examiner conducted a structured diagnostic interview of the child. Multivariate analysis of covariance showed that family composition had a significant effect on the occurrence of stressful events and change in income but not children's adjustment. Hierarchical multiple regression correlations indicated the most powerful predictors of child adjustment were family competence variables which accounted for 21% of the variance in child adjustment scores. In contrast, family composition accounted for only 8% of variance in child adjustment scores. Further, hierarchical multiple regression correlations indicated that higher levels of family functioning were associated with families where parental hostility was low and parents displayed few rejecting behaviors while practicing consistent and appropriate discipline.     

Latinas with Arthritis: Effects of Illness, Role Identity, and Competence on Psychological Well-Being

Tested a theoretical model on the effects of social role identity, illness intrusion, and competence on psychological well-being among 109 low-income Latinas with arthritis. All six roles studied were rated as highly important identities. Sex-role nontraditionalism was associated with less importance of the homemaker, mother, and grandmother roles. Negative affect increased as a function of intrusions into valued identities. Having important role identities contributed to feelings of competence (i.e., self-esteem and self-efficacy), which in turn, contributed to psychological well-being. Competence also mediated the effects of pain, identity, and illness intrusions on psychological well-being. Results suggest competence processes play an important role in well-being.     

Conversational skill and locus of perception

The present study attempted to identify behavioral skills associated with global perceptions of communication competence and to determine if the relationship between competence and skills varies as a function of perceptual locus. Fifteen dyadic conversations were videotaped. Each interactant rated self and partner and was rated by four observers who viewed each tape. Results indicated that subjects' perceptions of their partners' skills accounted for 87% of the variance in subjects' ratings of partners' competence and 80% of the variance in subjects'self-perceived confirmation. Observers' ratings of subjects' skills predicted 83% of the variance in observers' ratings of subjects' competence. Observers'ratings of subjects'skills were unrelated to subjects' self-rated competence.     

The Heterosocial Assessment Inventory for Women: A psychometric and behavioral evaluation

This paper presents a preliminary psychometric and behavioral evaluation of the Heterosocial Assessment Inventory for Women (HAI-W), a novel self-report instrument that evaluates five dimensions that may influence performance in 12 heterosocial situations: likelihood of initiation, anxiety, skillfulness, expectation of outcome, and influence of attractiveness. Study I obtained acceptable reliability and concurrent validity data and described the factor structure of the HAI-W with female college students. Study II found a significant relationship between the HAI-W factors and global ratings of the role-play performances of high- and low-heterosocially competent female college students as rendered by the male confederate, peer judges, and expert judges. The implications of these findings for the multidimensional assessment and facilitation of heterosocial competence are discussed.This study is part of a dissertation submitted to the Department of Psychology, Georgia State University, under the direction of Michael A. Milan. Portions of these data were presented at the Annual Meeting of the Association for Advancement of Behavior Therapy, Los Angeles, 1982.
