Genetic and Environmental Effects on Openness to Experience, Agreeableness, and Conscientiousness: An Adoption/Twin Study

ABSTRACT Previous research has indicated that extraversion and neuroticism are substantially affected both by genotype and environment. This study assesses genetic and environmental influences on the other three components of the five-factor model of personality: Openness to Experience, Agreeableness, and Conscientiousness. An abbreviated version of the NEO Personality Inventory (NEO-PI) was administered to 82 pairs of identical twins and 171 pairs of fraternal twins reared apart and 132 pairs of identical twins and 167 pairs of fraternal twins reared together. Estimates of genetic and environmental effects for Openness and Conscientiousness were similar to those found in other studies of personality: Genetic influence was substantial and there was little evidence of shared rearing environment. Results for Agreeableness were different: Genetic influence accounted for only 12% of the variance and shared rearing environment accounted for 21% of the variance. Few significant gender or age differences for genetic and environmental parameters were found in model-fitting analyses.     

New Careers Model Revisited: The Importance of Mentoring

The authors report a study that suggests the career paths of workers on short-term federal projects may be enhanced as a result of developing a relationship with a mentor through such projects.     

Morale and Job Satisfaction Among Nurses: What Can Hospitals Do?

In an attempt to account for morale and job satisfaction among 314 nurses, this study investigated the influence of work-related and interpersonal variables. Morale on the unit was directly related to supervisor support, co-worker relationships, and work recognition. Personal morale was accounted for by recognition, physical environment, the job itself, and pay. Job satisfaction was predicted by personal morale, work commitment, job clarity, work pressure, and innovation. Suggestions for improving nurse morale and job satisfaction are made.     

Small Wins: Perceptual Focus,Efficacy, and Cooperation in a Stage-Conjunctive Social Dilemma1

A multi-stage social dilemma was used to explore the notion that focusing on part rather than all of a complex problem would affect self-efficacy and action. In two experiments subjects considered a multi-stage game asking them to invest an initial sum of money in hopes of earning a larger bonus to be paid if provision points were met at all stages (a “stage-conjunctive” task). Results indicated that under most conditions considered, presentation of the whole problem encouraged cooperation. The opposite pattern occurred when group members were asked to complete very demanding stages first. We suggest that these results depend strongly on the stage-conjunctive nature of our task.     

SELF-REPORTED ASSERTIVE JOB-SEEKING BEHAVIORS OF MINIMALLY EDUCATED JOB HUNTERS

Little research attention has focused on the job-search behavior of minimally educated workers. The primary objective of the studies reported was to examine the relationship of self-reported assertive job-hunting behavior to acquisition of employment among minimally educated workers. The results of three studies provide: (a) construct validity evidence for the Assertive Job-Hunting Survey (AJHS; Becker, 1980), (b) evidence for construct similarity across minimally educated job seeker and college student populations, (c) evidence of a significant relationship between the AJHS and both subjective and objective job acquisition criteria in postdictive and predictive research designs, and (d) evidence that the AJHS, a measure of a non-cognitive variable, can make a unique contribution to the prediction of job acquisition beyond cognitive ability measures.
