To what extent do adolescents and their friends socialize each others’ attitudes toward immigrants? Can friends’ positive attitudes toward immigrants counter adolescents’ negative attitudes toward immigrants, and do friends’ negative attitudes decrease adolescents’ positive attitudes? These questions were examined by following a large (N?=?1,472) friendship network of adolescents (49.2 % girls; M age?=?13.31 at first measurement) across three annual measurements. Selection and influence processes regarding tolerance and xenophobia were distinguished with longitudinal social network analyses, controlling for effects of age, gender, and immigrant background. Findings showed that friends’ tolerance predicted increases in adolescents’ tolerance and friends’ xenophobia predicted increases in adolescents’ xenophobia. Moreover, friends’ tolerance predicted a lower likelihood of adolescents’ xenophobia increasing. The current results suggest that interventions should distinguish between tolerance and xenophobia, as these appear to represent two separate dimensions that are each influenced in specific ways by friends’ tolerance and xenophobia.  相似文献

High-pressure X-ray diffraction studies on gadolinium sesquioxide (Gd2O3) have been carried out up to a pressure of ~25 GPa in a diamond-anvil cell at room temperature. Gadolinium oxide, which has a cubic or bixbyite structure under ambient conditions, undergoes an irreversible structural phase at around 12 GPa. The high-pressure phase has been identified as a hexagonal La2O3-type structure. The bulk modulus and its pressure derivative of this phase have been calculated.  相似文献

This report presents results from a study of the dimensionality and longitudinal stability of some common self-reported somatic complaints in teenage girls. Data were supplied by the Swedish longitudinal research program “Individual Development and Adaptation”. At four age levels (age 10, 13, 15, and 16 years) a representative sample of approximately 500 girls filled out questionnaires on various adjustment problems, including some typical somatic complaints. A separate dimension of somatic complaints was identified at each age level through factor analysis of the questionnaire data. Correlational stability of somatic complaints was not high until middle adolescence. At this age fairly stable patterns of somatic complaints were also found at the individual level; different somatic complaints were not found to be interchangeable. The results support the interpretation of girls' somatic complaints as a single, meaningful dimension in late childhood and adolescence. This dimension may be hypothesized to constitute a psychological process, somatization, manifesting itself in fairly stable patterns at the individual level in middle adolescence.  相似文献

Over the last few decades, increased flexibility and lack of stability in employment has made job insecurity a work stressor that affects more and more employees. Since worrying about potential job loss (quantitative job insecurity) or possible loss of valued job features (qualitative job insecurity) constitutes a subjective perception, it has been claimed that personality factors may be decisive for job insecurity perceptions. Furthermore, the perception of a stressor, in this case job insecurity, could be argued to be dependent on appraisals of available coping resources. This study investigates whether core self-evaluations predict job insecurity perceptions, and whether coping mediates this relationship, in a two-wave data set from a Swedish sample of white-collar workers (N = 425). The results show that core self-evaluations had a negative total effect on both qualitative and quantitative job insecurity. Core self-evaluations were positively related to problem-focused coping but not to emotion-focused coping. However, there was no mediating effect of coping style on the association between core self-evaluations and job insecurity.  相似文献

Perceived job autonomy has been recognized as a central tenet of work design, leading to a range of positive outcomes. Still, scholars have rightfully questioned its predictive role for several outcomes, including turnover intention as the two have been found to be virtually unrelated. In line with calls for more complex research on the predictive role of perceived job autonomy on employee outcomes, the purpose of this study was to investigate whether the relationship between perceived job autonomy and turnover intention may be prone to contextual influences. Two cross-sectional surveys among 680 Norwegian employees from different public service organizations showed that the relationship between perceived job autonomy and turnover intention was moderated by perceived supervisor support. In support of our hypothesis, the form of the moderations revealed that perceived job autonomy was negatively related to turnover intention only for employees reporting high levels of perceived supervisor support. Implications for practice and directions for future research are discussed.  相似文献

Stressful working environments are commonly assumed to create conditions that can lead to bullying. Although environmental factors may relate to both exposure to and perpetration of workplace bullying, empirical knowledge is still limited regarding how environmental factors and bullying is causally linked. In line with interpretations of previous cross-sectional findings, the present study investigated an individual-level target-oriented model of role stressors as antecedents of exposure to workplace bullying, applying a two-wave longitudinal sample of the Norwegian working population. Results from structural regression analyses failed to identify any significant relationships between the role stressors and subsequent exposure to workplace bullying. However, prior exposure to workplace bullying accounted for subsequent variation in role ambiguity, role conflict, and role overload alike. The findings of the present study question conclusions regarding causality made in previous cross-sectional research on work-related factors as antecedents of exposure to workplace bullying. We argue that future research may benefit from adopting multilevel and actor-oriented perspectives in order to more fully understand how causal relationships between environmental factors and workplace bullying unfold.  相似文献

This study investigates the characteristics of whistleblowers, the prevalence and nature of whistleblowing, and the occurrence of retaliation after whistleblowing using a randomly selected and representative sample of Norwegian employees. The results showed that 12 per cent self-reported as whistleblowers according to an operational definition. Being a leader, or a union or personnel safety representative was significantly related to whistleblowing. The most frequently reported wrongdoing was harassment conducted by a single colleague. Wrongdoer(s) received mixed responses, from no reaction to reprimand. Even though most whistleblowers were not sanctioned, they reported less job satisfaction and more workplace bullying than did nonwhistleblowers. Only a few were rewarded. For the most part, wrongdoing was stopped or reduced. However, whistleblowing was only partially effective, because whistleblowers reported lack of feedback about the result of their report. Results also showed that the status of the wrongdoer was related to the reaction he or she received afterwards, as were the type of wrongdoing and the effect on the wrongdoing, and the type of wrongdoing and the effect on the wrongdoer(s). Potential explanations for the results, such as the type of sample and power distance, are discussed. Practical implications of the study are also addressed, such as the importance of providing feedback to whistleblowers.  相似文献

The aim of this study was to test the hypothesis that male assistant nurses, representing a small gender minority in their profession and in the work organizations they inhabit, are more often exposed to bullying at work than their female colleagues. In 1999, a random sample of the assistant nurses organized in the Norwegian Union of Health and Social Workers were mailed a questionnaire; 7478 out of 12,000 (62.3%) completed the questionnaire. The sample of the present study comprised the 6485 respondents who were vocationally active and not on leave. 3.8% (n?=?247) of the respondents were men; 10.2% (n?=?25) of the men and 4.3% (n?=?265) of the women reported that they had been exposed to bullying at work during the previous 6 months, χ2?=?19.12, df?=?1, p?<?.0001. The association between gender and exposure to bullying at work remained strong and significant (odds ratio?=?2.29; 95% confidence interval?=?1.39?-?3.78; p?=?.001) even after adjustment for a series of background factors. The study supports the hypothesis that male assistant nurses are more often exposed to bullying at work than their female colleagues.  相似文献

Workplace bullying is a serious hazard in every day working life that needs to be assessed carefully. In order to achieve such a goal, both victims of severe bullying as well as targets of less intensive bullying need to be identified, the latter in order to prevent further escalation into severe bullying. Previous research has mainly offered simple and crude measures of who is and who is not a victim of bullying. In this article we show how cutoff scores for the scale Negative Acts Questionnaire–Revised (NAQ-R) can be calculated. Based on a representative sample of the Norwegian workforce, we formulated 2 cutoff points or thresholds for the NAQ-R with a Receiver Operation Characteristic curve. Employees with a score lower than 33 are not bullied, employees with a score between 33 and 45 may be considered as being bullied occasionally, and employees who score above 45 can be considered to be victims of workplace bullying. As the NAQ-R is used in more than 300 research projects worldwide, we hope to inspire other scholars to define similar cutoff points. In addition, we hope that clear cutoff scores may be of assistance to practitioners for designing interventions regarding workplace bullying in line with the identified problems.  相似文献
