Worksite intervention model for facilitating changes in physical activity, fitness, and psychological parameters

The purpose was to examine the effectiveness of a physical activity intervention which combined behavior-change strategies with a variety of physical activities for 30 sedentary adults in a 12-wk. intervention that included behavior-change strategy sessions and supervised physical activity. Before and after the intervention, psychological and physiological variables were measured. Statistically significant changes right after the intervention included (1) an increase in physical activity participation, (2) an increase in muscular endurance, flexibility, and predicted VO2 max, and (3) a decrease in the number of barriers to physical activity. Changes in physical self-perception, a psychological variable often linked to increased physical activity, were not statistically significant, but effect sizes were large. The use of behavior-change strategies in conjunction with a variety of physical activities may be useful in improving physical and psychological well-being in previously sedentary adults. Stability of change requires study.     

The construct and criterion validity of emotional intelligence and its potential utility for management studies

In this study, the authors reviewed the definition of emotional intelligence (EI) and argued that El is conceptually distinct from personality. In Study 1, the authors showed that EI was related to yet distinct from personality dimensions and that it had incremental predictive power on life satisfaction. The authors examined the construct validity of self-reports and others' ratings of EI using two samples in Study 2. In a student sample, parents' ratings explained additional variance in the students' life satisfaction and feelings of powerlessness after controlling for the Big Five personality dimensions. In the work sample, peer ratings were found to be significant predictors of job performance ratings provided by supervisors after controlling for the Big Five personality dimensions. Other implications for future research on EI are discussed.     

Effective obesity treatments

To curb the epidemic of obesity in the United States, revised Medicare policy allows support for efficacious obesity treatments. This review summarizes the evidence from rigorous randomized trials (9 lifestyle trials, 5 drug trials, and 2 surgical trials) on the efficacy and risk- benefit profile of lifestyle, drug, and surgical interventions aimed at promoting sustained (= 2 years) reductions in weight. Both lifestyle and drug interventions consistently produced an approximate 7-lb (3.2-kg) weight loss that was sustained for 2 years and was associated with improvements in diabetes, blood pressure, and/or cardiovascular risk factors. Surgical interventions have a less solid empirical base but offer promise for the promotion of significant and sustained weight reduction posttreatment in the morbidly obese but with possible significant short-term side effects. In summary, there is strong and consistent support from rigorous randomized trials that lifestyle or drug interventions result in modest weight loss with minimal risks but disproportionate clinical benefit. Combinations of lifestyle, drug, and, where appropriate, surgical interventions may be the most efficacious approach to achieving sustained weight loss for the widest diversity of patients.     

Prediction of work functioning following accidental injury: The contribution of PTSD symptom severity and other established risk factors

Responses to a mail survey were used to investigate the contribution of PTSD symptom severity to work functioning in 69 previously employed adult survivors of accidental injury approximately 8 months post‐hospitalization. Associations of PTSD symptom severity with other established risk factors for poor work functioning were also examined. Participants were initially divided into three groups based on PTSD symptom severity and analysis of variance undertaken to determine the differences in work functioning between survivors with PTSD, subclinical PTSD, and no PTSD. As anticipated, survivors with PTSD reported significantly poorer work functioning than those with subclinical PTSD and no PTSD. Those with subclinical PTSD, however, reported significantly lower levels of work functioning than survivors with no PTSD, suggesting that this population may also be at risk of poor outcomes and in need of vocational interventions post‐accident. To determine the influence of PTSD symptom severity on work functioning over and above other established risk factors, a two‐model hierarchical regression that included the established risk factors in the first model and PTSD in the final model was undertaken. Results revealed that PTSD symptom severity uniquely predicted work functioning after controlling for the influence of other contributing risk factors. A composite of seven risk factors, including PTSD symptom severity, was shown to predict 62% (57% adjusted) of the variance in work functioning but only pre‐accident occupation, physical functioning, and PTSD severity significantly contributed to the prediction. Findings suggest that the rehabilitation management of people with PTSD or subclinical PTSD following accidental injury would benefit from early identification by the established predictors together with an integrated approach to physical, psychological, and vocational interventions.     

Hoist on your own petard: When prejudiced remarks are recognized and backfire on speakers

The purpose of this research was to explore when people recognize prejudice in those who make bigoted remarks, and whether such expressions of bigotry backfire to harm those who express them. The results of Study 1 suggest that people attribute prejudice to speakers who make stereotypical generalizations about either ascribed (e.g., race, age, sexual orientation) or assumed (e.g., occupational) groups, but have more difficulty recognizing prejudice in those who express positive stereotypes. Study 2 found that bigoted speakers were perceived as less likeable, even by in-group members who agreed with their remarks. Study 3 replicated these findings in a more realistic paradigm, and found that those who made prejudiced remarks were spontaneously described as bigoted. Such negative reactions were again obtained even from like-minded in-group members, with follow-up analyses suggesting that these reactions primarily characterized a subset who spontaneously noted the bigotry and that these reactions mediated negative impressions.     

Maternal discrimination and the development of sex differences in exploratory behaviour in infant spiny mice (Acomys cahirinus)

The present paper reports sex differences in exploratory behaviour by infant Spiny Mice, Acomys cahirinus, that may, in part, be related to differences in maternal behaviour towards pups; like some other rodents, mother Acomys differentiate behaviourally between male and female pups. In Experiment 1 infant Acomys were allowed to explore a novel arena. This experiment showed that even by Day 3 (the day of birth=Day 1) female Acomys explored a novel environment more than males; they entered the arena sooner than males and spent more time in contact with a novel object. Experiment 2 showed that infant females were more active than males when observed in the home cage in the presence of their parents and made more approaches to the mother. Mothers, on the other hand, directed more licking behaviour towards males. Experiment 3 focused on the exploratory behaviour of individual pups in the presence of the mother. Given access to a large, complex arena, female pups explored more than males. The results also showed that mothers direct more of their social interactions towards sons than daughters, particularly when pups are about a week old. Some mothers appear to “direct” the movement of their offspring, by blocking their forward movement; this was done more often to male than to female pups. The data suggest that the previously observed changes in exploratory behaviour at this time, and the emergence of sex differences in exploration, may in part depend upon the mothers' reactions to pups by sex.     

From Bourdieu and Wolin, `Inside and Outside the Box': A Frame for the Special Issue

Utilizing the writings of Pierre Bourdieu and Sheldon Wolin,this paper introduces a special issue on ``Educational Rights andEntitlements.' Its purpose is to characterize and critique `the box ofliberalism' that both advances and constrains what is conceived andenacted in education. Following it are a set of significantcontributions from the sixth biennial conference of the InternationalNetwork of Philosophers of Education, August 1998, Ankara.     

The mediating effects of time structure on the relationships between time management behaviour,job satisfaction,and psychological well‐being

This article examined the relationship between time structure and Macan's process model of time management. This study proposed that time structure—‘appraisal of effective time usage’—would be a more parsimonious mediator than perceived control over time in the relationship between time management behaviours and outcome variables, such as job satisfaction and psychological well‐being. Alternative structure models were compared using a sample of 111 university students. Model 1 tested Macan's process model of time management with perceived control over time as the mediator. Model 2 replaced perceived control over time by the construct of time structure. Model 3 examined the possibility of perceived control over time and time structure as being parallel mediators of the relationships between time management and outcomes. Results of this study showed that Model 1 and Model 2 fitted the data equally well. On the other hand, the mediated effects were small and partial in both models. This pattern of results calls for reassessment of the process model.
