Using cluster analyses, this study explored the relations among racial identity, perceived discrimination, and psychological concerns among 189 Caribbean Black American and African American adolescents. Findings showed that for all participants, less mature racial identity profiles were significantly related to perceived discrimination and psychological concerns. However, nuances in racial identity profiles between Caribbean Black American and African American participants suggest subtle ethnic group differences in racial identity development. Implications for practitioners and research are discussed. Usando análisis cluster, este estudio exploró las relaciones entre identidad racial, discriminación percibida y preocupaciones psicológicas en 189 adolescentes afroamericanos y americanos negros caribeños. Los hallazgos mostraron que, para todos los participantes, los perfiles de identidad racial menos maduros estaban significativamente relacionados con una discriminación percibida y preocupaciones psicológicas. Sin embargo, los matices de los perfiles de identidad racial entre los participantes afroamericanos y americanos negros caribeños sugieren unas diferencias sutiles entre ambos grupos étnicos en el desarrollo de la identidad racial. Se discuten las implicaciones para practicantes e investigadores.  相似文献

Purpose

Identifying the characteristics of chief executive officers (CEOs) has been a longstanding goal in leadership and individual differences research. The purpose of this exploratory study was to consider which individual difference and career path variables differentiate CEOs from other senior managers.

Design/Methodology/Approach

Participants (N = 1152) were UK-based senior managers (n = 1040) and CEOs (n = 112) who completed a self-report measure of the Five Factor Model of personality (NEO-PI-R), a measure of cognitive ability (graduate and management aptitude test), and answered a number of additional questions on their career paths as part of development centres. Analyses comprised inter-individual mean difference tests, intra-individual external profile analysis and logistic regression.

Findings

Results indicated that personality facets of impulsiveness, vulnerability, activity and dutifulness showed the largest mean differences. No significant effects were found for the criterion profile pattern, but significant effects were found for profile level. Of the additional predictors, career path variables were the strongest predictors of CEO status.

Implications

The combination of significant effects across domains of individual differences and career path variables emphasizes the importance of a multivariate approach in the study of leadership, top management teams and career progression.

Originality/Value

The current study combines personality, cognitive ability, demographic and career path variables, and applies intra-individual methodologies to explore the characteristics of the very top level of organisational hierarchy.

Research on consolidation of long-term memory suggests that acute immune system activation induced by endotoxin lipopolysaccharide (LPS) may disrupt consolidation of newly acquired learning. Adult male Sprague-Dawley rats were trained to perform a simple Y-maze task and were immediately afterwards administered LPS (15 microg/kg) or saline. After a seven-day interval, subjects were returned to the Y-maze and were retrained to criterion. It was found that subjects treated with saline required significantly fewer trials to relearn the task relative to the LPS group and a no-partial-learning control group, which themselves did not differ. These results are most readily explained in terms of a disruptive effect of acute immune system activation on consolidation of newly induced acquired memories.  相似文献

Although work-family research has mushroomed over the past several decades, an implementation gap persists in putting work-family research into practice. Because of this, work-family researchers have not made a significant impact in improving the lives of employees relative to the amount of research that has been conducted. The goal of this article is to clarify areas where implementation gaps between work-family research and practice are prevalent, discuss the importance of reducing these gaps, and make the case that both better and different research should be conducted. We recommend several alternative but complementary actions for the work-family researcher: (a) work with organizations to study their policy and practice implementation efforts, (b) focus on the impact of rapid technological advances that are blurring work-family boundaries, (c) conduct research to empower the individual to self-manage the work-family interface, and (d) engage in advocacy and collaborative policy research to change institutional contexts and break down silos. Increased partnerships between industrial-organizational (I-O) psychology practitioners and researchers from many industries and disciplines could break down silos that we see as limiting development of the field.  相似文献

We describe here a new test for dispositional optimism and pessimism in young children, the Parent‐rated Life Orientation Test of children (the PLOT) and assess its psychometric properties. Two hundred and twenty one mother–father pairs rated their children's (mean age = 8.1, SD = 0.3 years) dispositional optimism and pessimism using a new scale, the PLOT, including four optimism and four pessimism items. We associated the PLOT with parent‐rated self‐esteem (Behavioral Rating Scale of Presented Self‐Esteem in Young Children), social competence (Social Competence and Behaviour Evaluation Scale, the SCBE‐30), psychiatric symptoms (Child Behaviour Checklist, the CBCL) and temperament (Children's Behaviour Questionnaire, the CBQ) of the child. A confirmatory factor analysis (CFA) of the mother‐ and father‐rated PLOT revealed a significantly better fit for a two‐ over a one‐factor solution (p < 0.001). The optimism and pessimism subscales displayed good reliabilities, inter‐parental agreement and modest to moderate associations, in the expected direction, with the measures of self‐esteem, social competence, temperament and behaviour problems. To conclude, the PLOT shows good construct and convergent validity and reliability. The findings encourage its use to assess early emerging generalized expectancies of positive and negative outcomes in young children. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

A vast body of literature has reported on the association between unemployment and poor psychological health. Nonetheless, there remains limited understanding of the influence of meaningfulness of time use, suggested by some to be the key mediator between time use and health. This project set out to explore the association between meaningful time use and health in 18‐ to 25‐year‐old unemployed people. In April 2007, 150 unemployed 18‐ to 25‐year‐old Australians (56% female) completed an online survey package exploring meaningfulness of time use and health. Hierarchical stepwise regression equations were developed to analyse the relationship between psychological health and measures of meaningful time use. Results provided partial support for the hypothesis that measures of meaningful time use would contribute to the prediction of psychological health. The addition of the person measure for the combined construct of ‘meaningful time use’ failed to make a significant contribution towards the prediction of psychological health. However, ‘reason for doing the activity’ emerged as a significant predictor. Findings provide preliminary evidence for the establishment of activity‐based programs to support young unemployed people. Further research is required to evaluate the outcomes of such programs and to replicate this study with other groups of unemployed individuals. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

The present study was designed to explore the effects of warned and unwarned demand transitions in vigilance on performance and self-reported stress. Twenty observers (10 women and 10 men) were assigned at random to each of six conditions resulting from the factorial combination of signal salience (high and low salience signals) and switching (no switch, switch with warning, and switch without warning). Performance metrics and self-reported stress state (Task Engagement, Distress, and Worry) were collected. While demand transitions did destabilize subsequent performance, increasing intra-individual variability, overall performance efficiency was uninfluenced by either switching or warning. Demand transitions, whether warned or not, increased self-reported distress. A dynamic model of performance stress may be necessary and research employing vigilance tasks in the future may be useful for developing this performance-stress model.  相似文献

OBJECTIVE: A number of studies have shown an association between socioeconomic status (SES) and cardiovascular reactivity to acute stress. In addition, the authors recently reported that higher early childhood blood lead (Pb) levels are associated with significantly greater total peripheral (vascular) resistance (TPR) responses to acute stress. It is not known whether the SES-TPR association is mediated by underlying differences in blood lead levels. DESIGN: Participants were 9.5-year-old children (N=122) with established early childhood blood lead levels. MAIN OUTCOME MEASURES: Family SES was measured using the Hollingshead Index, blood lead levels were abstracted from pediatrician and state records, and children's cardiovascular responses to acute stressors were measured in the laboratory with impedance cardiography and an automated blood pressure monitor. RESULTS: Lower family SES was shown to be associated with significantly higher blood lead levels as well as significantly heightened systolic blood pressure, diastolic blood pressure, and TPR responses to acute stress tasks. A mediational analysis confirmed that Pb was a significant mediator of the SES-TPR reactivity association; some evidence also suggested moderation. CONCLUSION: These results suggest the importance of considering the chemical environment as well as social and psychological environment when evaluating cardiovascular effects of low SES.  相似文献

The purpose of the present study was to test whether or not a biodata instrument could be used to predict turnover, organizational commitment, and job performance in healthcare organizations. A criterion‐related, predictive validation strategy was used using a sample of 672 employees from two different hospitals in the southeastern United States. Supervisory ra0tings of organizational commitment and job performance were highly correlated with responses to the organizational commitment scale and the total score on the biodata instrument, respectively. Actual turnover was correlated with responses to the retention scale, although the effect size was small. Additionally, the study examined the fairness of biodata in this context as it relates to differences in performance among minority and non‐minority candidates. The findings in this study suggest that using such an instrument may provide organizations with the potential to improve organizational commitment and job performance, while reducing turnover with minimal group differences.  相似文献
