Abstract In a sample of 97 male adolescents, individual differences in health complaints were predicted by personality traits and by self-reported health/risk behaviors. Anxiety and loneliness were measured at Times 1 and 2, and health locus of control, various behaviors and health complaints were assessed at the end of the two-year study. A causal model was specified, employing anxiety and loneliness as distal predictors, health locus of control and behaviors as proximal predictors of health complaints. It turned out that anxiety was the most powerful single predictor, and that loneliness exerted a direct effect on health locus of control and behaviors and an indirect effect on health complaints. Risk behavior as well as health behavior were related to complaints. Social integration facilitated not only health behavior but also risk behavior. 相似文献

Pro‐age advertising campaigns feature mature models, at least in part to reduce the depiction of unrealistic body ideals associated with the use of young models. The introduction of mature models into advertising campaigns may have hitherto unexamined effects on viewers' self‐esteem. We therefore compared the impact of mature and young models on women's levels of self‐esteem. Young adult and middle‐aged women were subtly exposed to young or pro‐age female models before completing an affective priming task designed to measure self‐esteem. As predicted, exposure influenced only appearance‐based self‐esteem, but not global self‐esteem. Furthermore, age congruency led to decreased self‐esteem, whereas age incongruency led to increased self‐esteem. Specifically, exposure to young models decreased young women's self‐esteem, just as exposure to mature models decreased middle‐aged women's self‐esteem. By contrast, exposure to mature models increased young women's self‐esteem, and exposure to young models increased middle‐aged women's self‐esteem. The implications for marketing campaigns are discussed. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Fear of death features in both historical and contemporary theories of religion, but the relationship between death anxiety and religious belief is still ambiguous, largely due to the use of inappropriate or imprecise measures. The current studies therefore aimed to develop a valid, targeted measure of respondents' tendency towards religious belief, the ‘Supernatural Belief Scale’ (SBS), and to use the SBS to examine the relation between death anxiety and religious belief. Results indicate that the SBS shows high reliability and convergent validity and that its relation to death anxiety depends on participants' religious identification: ‘religious’ participants fear death less the stronger their religious beliefs, whereas ‘non‐religious’ participants are more inclined towards religious belief the more they fear death. These studies contribute a new measurement tool for research on religious belief and provide a starting point for an experimental integration of discrepant research findings.

The effect of ultrafine-grained structure formation in Mg–Zn–Zr alloy ZK60 on its mechanical response was investigated at strain rates ranging from quasi-static to dynamic regimes. The study demonstrated that the strength characteristics of the material rise significantly with increasing strain rate, while its ductility is reduced. These effects are particularly pronounced in the dynamic loading regime, at strain rates in the (1?5)?×?102?s?1 range. In the ultrafine-grained alloy ZK60, the energy absorption per unit volume, W, is enhanced by grain refinement by a factor as high as eight for the highest strain rate of 5?×?102?s?1 investigated. The analysis is focused on the microstructure features that bring about the observed improvement of the tensile characteristics, as well as the deformation and fracture modes prevalent at different strain rates. The results obtained contribute to the exploration and understanding of dynamic behaviour of magnesium alloys. 相似文献

Cognitive theories of emotion propose that the interpretation of emotion-eliciting situations crucially shapes affective responses. Implicit or automatic biases in these interpretations may hinder emotion regulation and thereby increase risk for the onset and maintenance of psychological disorders. In this study, participants were randomly assigned to a positive or negative interpretation bias training using ambiguous social scenarios. After the completion of the training, a stress task was administered and changes in positive and negative affect and self-esteem were assessed. The results demonstrate that the interpretation bias training was successful in that participants exhibited a tendency to interpret novel scenarios in accordance with their training condition. Importantly, the positive training condition also had a protective effect on self-esteem. Participants in this condition did not exhibit a decrease in self-esteem after the stress task, whereas participants in the negative condition did. These results demonstrate that implicit cognitive biases can be trained and that this training affects self-esteem. Implications of these findings for research on psychopathology and emotion regulation are discussed. 相似文献

This study links idiosyncratic deals (i-deals) to job design theory. It investigates the impact of individually negotiated job changes on performance, self-efficacy, and psychological strain through their intervening effects on work design. Based on a sample of 187 health care professionals employed by a hospital in Germany, three types of work design-related i-deals were investigated: (1) task, (2) career, and (3) flexibility i-deals. Consistent with hypotheses, the three types of i-deal had differential effects on work characteristics, and each in turn related to different outcomes. Specifically, job autonomy mediated the task i-deals—job performance relationship; skill acquisition mediated the career i-deals—occupational self-efficacy relationship; and reduced work overload mediated the flexibility i-deals—emotional and affective irritation relationships. Leader–Member Exchange was confirmed as an antecedent of all three types of i-deals. Task, career, and flexibility i-deals are discussed as ways to make work more intrinsically motivating, ensure one’s professional advancement, and balance workplace stressors. 相似文献

Research on school tracking has provided evidence that students with immigrant backgrounds are overrepresented in the lower school tracks. As teachers are the main decision makers when it comes to tracking, we investigated whether teachers’ tracking judgments are biased by the immigrant backgrounds of the students and how teachers’ tracking judgments are affected by inconsistencies in students’ academic profiles. Drawing on dual process models of judgment formation, we conducted two experimental studies to investigate teachers’ judgments. The results of both studies showed less favorable teacher judgments of students with immigrant backgrounds than of students without immigrant backgrounds. Students with inconsistent academic profiles were also judged less favorably than students with consistent profiles. Think aloud data indicated careful processing of all information both for students with immigrant backgrounds and students with inconsistent profiles. Results are discussed with regard to their underlying mechanisms as well as with regard to their implications for teacher training. 相似文献

Pour résoudre les paradoxes bien connus de la mécanique quantique, on propose une interprétation par ramification (ou univers parallèles) analogue à celle d’Everett, mais avec des différences: (i) on propose une infinité continue de branches, dont les poids (o[ugrave] probabilités) se calculent par intégrale; (ii) les branches sont séparées par des ramifieurs qui se propagent à la vitesse de la lumière. Lorsqu’est négligeable la composante d’énergie négative de la fonction d’onde, le poids de chaque branche en un point donné u est égal au flux du quadrivecteur (courant-densité de présence), soit à travers l'élément d’écran antérieur à u sur lequel l'impact est perçu, soit à travers le cône passé de u si aucun impact n’est perçu. In order to solve well-known paradoxes in quantum mechanics, we propose a reworking of Everett's interpretation with ramified branches (or many worlds), yet somewhat different: (i) branches form an infinity continuum and each weight (probability) is defined by an integral; (ii) branches are separated by ramifiers which propagate themselves with the velocity of light. Assuming we can neglect the negative-energy component in the wave function, then the weight of each branch at a given point u is equal to the flux of the quadrivector (current-presence density), either through the screen element where the impact occurs, or through the past light-cone of u if no impact occurs. 相似文献
