Resource loss,resource gain,PTSD, and dissociation among Ethiopian immigrants in Israel

The aim of this study was to examine the loss and gain of resources, posttraumatic stress disorder (PTSD) and dissociation among Jewish Ethiopian immigrants in Israel following exposure to stressful events occurring pre‐, peri‐, and post‐migration. Resources are defined as objects (e.g., housing), conditions (e.g., employment), personal (e.g., self‐esteem), or energy (e.g., culture). A random sample (N = 478) of three waves of immigrants participated in the research (N1 = 165; N2 = 169; N3 = 144). The data were collected in 2001. Age, loss and gain of resources, traumatic events peri‐migration, post‐migration difficulties, posttraumatic symptoms, and dissociation were assessed. The relationships between the variables were assessed with multiple hierarchical regressions predicting PTSD and dissociation with gain and loss of resources, over and above age, immigration wave, and trauma. A significant relationship was found between PTSD symptoms and loss of self‐esteem resources (r = 0.17 p < 0.001), while dissociation was positively associated with gain of housing resources (r = 0.20, p < 0.001). Both PTSD and dissociation were predicted by younger age. The findings are discussed in light of the conservation of resources (COR) theory (Hobfoll, 1988 ), of resource loss and gain among Ethiopian immigrants.     

A Developmental Meta-Analysis of Peer Conflict Resolution

A series of meta-analyses examine developmental trends in peer conflict resolution. Peer conflict resolutions are most likely to involve negotiation, with coercion and then disengagement the next most likely strategies. Patterns of conflict resolution differ with age. Coercion is common among children and disengagement is rare. Negotiation is prevalent among adolescents and young adults; the former do not differ in terms of coercion and disengagement, whereas the latter tend to avoid coercion in favor of disengagement. Conflict resolutions also vary as a function of peer relationships, assessment procedures, and reporters. Negotiation prevails in all peer relationships except those with siblings; there is more negotiation among romantic partners than among friends, and more negotiation among friends than among acquaintances. Negotiation is the overwhelming strategy of choice for those presented with hypothetical disputes, but actual conflicts tend to be resolved by coercion. Observers indicate that most conflicts involve coercive resolutions, in contrast to self-reports, which suggest that negotiation prevails. Although conclusions are qualified by the limited number of studies available, follow-up moderator analyses indicate that negotiation increases and coercion declines with age across most peer relationships, assessment procedures, and reporters such that different patterns of conflict resolution during childhood give way to the same relative ordering of strategies during young adulthood.     

Intruding male red swamp crayfish,Procambarus clarkii,immediately dominate members of established communities of smaller,mixed-sex conspecifics

The effects of competing asymmetries (intruder size advantage vs. prior residence) on dominance relationships were investigated in a laboratory setting. Sexually mature (Form I) male red swamp crayfish, 25%-27% larger than the average member of several mixedsex communities of 20-25 sexually mature conspecifics, individually intruded upon these communities on successive days. Each community was invaded once a day, with each of these large intruders invading every community once during the experiment. Five days after the last large intruder invasion, novel intruder group males, approximately the same size as the average community member, individually invaded the same communities, all communities being invaded once during a single day of testing. These novel intruders were used to differentiate the effects of intruder size from those effects of being put into a novel environment. During each intrusion, the frequencies of dominance, submission, aggressive standoffs, and nonaggressive interactions between the intruder and members of the community were recorded. The large intruders on each day immediately and virtually completely dominated all encountered community members, and the large intruders were significantly more dominant than the novel, smaller-sized intruders. The size advantage of the large intruders overwhelmed prior residence in influencing dominance outcomes, even in these well established communities. © 1995 Wiley-Liss, Inc.     

A dyadic examination of the role of relationship characteristics and age on relationship satisfaction in a formal mentoring programme

Research was conducted to test ideas derived from Wanberg, Welsh, and Hezlett's (2003) dynamic process model of formal mentoring to examine (1) the role of respect and communication in mentorship relationship satisfaction, and (2) whether the age of the mentor or the protégé would impact those relationship qualities. The sample was comprised of 117 matched mentor–protégé pairs from an organization's formal mentoring programme. We received survey data from both partners and used the Actor–Partner Interdependence Model to examine individual and dyadic effects. Data suggest that protégés' respect for the mentor and communication quality, as perceived by both partners, were independent predictors of mentorship relationship satisfaction. Protégés rated their relationships as more satisfying than did their mentors. Hypotheses regarding age differences in relational qualities were not supported. We suggest that researchers continue to examine formal relationships at the dyadic level, and that practitioners designing formal mentoring programmes consider interventions to enhance communication and respect.     

Dodging the double bind: the role of warmth and competence on the relationship between interview communication styles and perceptions of women’s hirability

In two studies we examine how feminine, masculine and hybrid impression management tactics affect perceptions of job applicants in interview settings. Study 1 (N = 133) results indicated that a hybrid tactic was more effective than a feminine tactic to portray competence. Similarly, a hybrid tactic was more effective than a masculine tactic to portray warmth. Further, perceptions of competence and warmth predicted ratings of likability and hirability. Study 2 (N = 222) replicated Study 1 and showed that applicant gender did not affect the results. The results indicated that hybrid tactics enable members of both genders to appear competent and warm in an interview.     

Recommendations implicit in policy defaults

Should people be considered organ donors after their death unless they request not to be, or should they not be considered donors unless they request to be? Because people tend to stay with the default in a variety of domains, policymakers' choice of default has large and often important effects. In the United States, where the organ-donation policy default is "not a donor," about 5,000 people die every year because there are too few donors. Four experiments examined two domains-being an organ donor and saving for retirement-where default effects occur and have important implications. The results indicate that default effects occur in part because policymakers' attitudes can be revealed through their choice of default, and people perceive the default as indicating the recommended course of action. Policymakers need to be aware of the implicit messages conveyed by their choice of default.     

Integrating psychological research on girls with feminist activism: a model for building a liberation psychology in the United States

A liberation psychology is needed to bridge the gap between psychology's focus on individual distress and broad social forces that foster such distress. We offer a model for bridging this gap by focusing on a specific area of psychology (psychological research on girls) and a specific social movement (feminist activism). Psychological research on girls and feminist activism share the common goal of improving the lives of girls and women. However, both have fallen short of this goal. This is due, in part, to the weaknesses associated with each endeavor and to the fact that the complementary strengths of each have remained isolated from the other. In this paper, we propose a common language and shared framework to integrate psychological research with feminist activism. First, we review the basic strengths and weaknesses associated with psychological research and feminist activism, with a particular focus on how they are distinct from one another. Second, we provide a taxonomic framework for integrating these two areas on the basis of the stress paradigm, with specific examples provided from our recent reviews of the literature and our own empirical work with adolescent girls. Finally, we conclude with recommendations for future work needed to integrate psychological research on girls with feminist activism toward the goal of building a liberation psychology in the United States.     

Space-Time Counterfactuals

A definition is proposed to give precise meaning to the counterfactual statements that often appear in discussions of the implications of quantum mechanics. Of particular interest are counterfactual statements which involve events occurring at space-like separated points, which do not have an absolute time ordering. Some consequences of this definition are discussed. This revised version was published online in June 2006 with corrections to the Cover Date.     

Illness perceptions or recurrence risk perceptions: What comes first? A longitudinal cross-lagged examination among cardiac patients

Objectives: Previous research suggested that illness perceptions provide the basis for illness risk perceptions through an inductive reasoning process. This study aimed to assess the direction of relationships between illness and recurrence risk perceptions over time, among cardiac patients.

Design: A longitudinal study was conducted among 138 patients undergoing coronary angioplasty. Self-report questionnaires measured perceived recurrence risk and illness perceptions one day and one month after catheterisation.

Results: Cross-lagged Panel Model Analyses revealed that higher perceptions of timeline, consequences and emotional representations of illness at hospitalisation were associated with higher recurrence risk perceptions one month later. Perceived personal control was the only illness perception with bi-directional associations: higher perceived personal control at hospitalisation was associated with higher recurrence risk perceptions one month later; and higher recurrence risk perceptions at hospitalisation was associated with lower personal control one month later.

Conclusions: The findings suggest that the associations between recurrence risk and illness perceptions can only partly be explained by inductive reasoning. Halo effects and defensive processes are suggested as complementary explanations for the observed associations between risk and illness perceptions.     

A WORKER MOTIVATION SCALE

A 70 item questionnaire was constructed using the rationale of several current value/expectancy theories of motivation and the results of two prior factor analyses of motivation items. It was completed anonymously by 240 employed adults in 35 organizations and the resulting factor analysis yielded a hierarchical structure of motivation and eight reliable subscales. Direct and indirect criterion measures also obtained via the questionnaire and covering job characteristics/components; satisfaction (need) levels for n ach, n affil, n power ; the four elements of Heider's attribution theory of motivation; and salary, education and job classification were used to validate the subscales. Support for the criteria was found and promising validities were indicated. Lastly, personal, job and organizational variables were included with the motivation subscales and criteria in a subsequent factor analysis to examine moderator effects of the obtained validities. Results are discussed in terms of motivation theories, validities, moderator effects in study designs, and future use of the questionnaire by other researchers with business-industrial samples.
