This study, conducted with a representative sample of employed and unemployed adults living in Switzerland (N = 2002), focuses on work conditions (in terms of professional insecurity and job demands), career adaptability, and professional and general well-being. Analyses of covariance highlighted that both unemployed and employed participants with low job insecurity reported higher scores on career adaptability and several dimensions (notably on control) than employed participants with high job insecurity. Moreover, structural equation modeling for employed participants showed that, independent of work conditions, adaptability resources were positively associated both with general and professional well-being. As expected professional outcomes were strongly related to job strain and professional insecurity, emphasizing the central role of the work environment. Finally, career adaptability partially mediated the relationship between job strain and professional insecurity, and the outcome well-being.  相似文献

通勤压力作为一种新型压力源,近年来逐渐成为组织管理领域的前沿话题。通勤压力是指个体在通勤过程中所遭遇的压力事件以及所产生的紧张反应,它对员工的工作态度、工作状态以及工作行为均会产生一定的负面影响,影响强度取决于员工的个人特征、家庭压力以及所处的工作情境。资源保存理论和控制理论是解释通勤压力消极影响的主要理论。未来研究可进一步完善测量工具,考察不同通勤模式的差异化影响效应,丰富边界机制等。  相似文献

Adolescents of today grow up in a connected world. While online communication offers great opportunities, it can also have negative impact on adolescents' life. In this work, we are interested in the use of online communication tools to share and create cyberhate content. Anchored in the general strain theory, we studied how social support (i.e., parental, peers and teacher support) may be related to cyberhate perpetration. We further tested how personal characteristics such as empathy, self-esteem and anxiety could predict the propensity to be involved as cyberhate perpetrators. We collected self-reported questionnaires of 1019 French young people (13.04 years; ranging from 9 to 17) and measured their perceived (a) parental, (b) peers and (c) teachers' support as well as their (d) empathy/benevolence, (e) self-esteem and (f) anxiety. We also measured cyberhate perpetration and the association between perpetration, social support and personal characteristics. Our results highlight that parental and teacher support represent protective factors for cyberhate perpetration. Our results further suggest that self-esteem is negatively linked to the propensity to cyberhate perpetration.  相似文献

Using a risky-choice framing paradigm, we investigated (a) the extent to which psychopathic features shape behavioral responses to potential losses vs. potential gains and (b) how these relations bear on real-world economic decision-making in a community sample (N =  475). Associations among psychopathic features, risk-seeking, sensitivity to framing, and financial practices were also examined. Disinhibition manifested positive relations with risk-seeking and maladaptive financial practices, whereas boldness manifested positive relations with risk-seeking and adaptive financial practices. Individuals high in disinhibition and/or meanness were significantly less likely to endorse risk seeking in negative frames. Results provisionally suggest boundary conditions for framing effects; in particular, certain psychopathic traits may render individuals modestly less susceptible to framing or bias them towards risk-taking in positive frames.  相似文献

With respect to theorisations of psychical splitting, this paper explores the psychical mechanisms that underlie different forms of social splitting. The paper first outlines Freud's and Kleins different theorisations of the psychical mechanisms of splitting, where the good is split from the bad, the inside split from the outside, and the painful disavowed. I then consider the psychical mechanisms of splitting that underlie ideological supports of certain social systems, specifically that of National Socialist Germany, East Germany during the Cold War period, and neoliberal capitalism. Here, I consider ideological splits between good and evil, the relation between external and internal splits, the relation between geographical, social and internal splitting, as well as splitting as disavowal of the other.  相似文献

The internal length is the governing parameter in strain gradient theories which among other things have been used successfully to interpret size effects at the microscale. Physically, the internal length is supposed to be related with the microstructure of the material and evolves during the deformation. Based on Taylor hardening law, we propose a power-law relationship to describe the evolution of the variable internal length with strain. Then, the classical Fleck–Hutchinson strain gradient theory is extended with a strain-dependent internal length, and the generalized Fleck–Hutchinson theory is confirmed here, by comparing our model predictions to recent experimental data on tension and torsion of thin wires with varying diameter and grain size. Our work suggests that the internal length is a configuration-dependent parameter, closely related to dislocation characteristics and grain size, as well as sample geometry when this affects either the underlying microstructure or the ductility of the material.  相似文献

People often form intentions but fail to follow through on them. Mounting evidence suggests that such intention‐action gaps can be narrowed with prompts to make concrete plans about when, where, and how to act to achieve the intention. In this paper, we pushed the notion of plan‐concreteness to test the efficacy of a prompt under a minimalist automated calling setting, where respondents were only prompted to indicate a narrower duration within which they intent to act. In a field experiment, this planning prompt significantly helped people to pay their past dues and get out of debt delinquency. These results suggest that minimalist automatic planning prompts are a scalable, cost‐effective intervention.  相似文献

In this work, we investigate the susceptibility of NiTi superelastic wires to the strain rates during tensile testing after hydrogen charging. Cathodic hydrogen charging is performed at a current density of 10?A/m² during 2–12?h in 0.9% NaCl solution and aged for 24?h at room temperature. Specimens underwent one cycle of loading-unloading reaching a stress value of 700 MPa. During loading, strain rates from 10?6 to 5?×?10?2??s?1 have been achieved. After 8?h of hydrogen charging, an embrittlement has been detected in the tensile strain rate range of 10?6 to 10?4?s?1. In contrast, no embrittlement has been detected for strain rates of 10?3?s?1 and higher. However, after 12?h of hydrogen charging and 24?h of annealing at room temperature, the embrittlement occurs in the beginning of the austenite-martensite transformation for all the studied strain rate values. These results show that for a range of critical amounts of diffused hydrogen, the embrittlement of the NiTi superelastic alloy strongly depends on the strain rate during the tensile test. Moreover, it has been shown that this embrittlement occurs for low values of strain rates rather than the higher ones. This behaviour is attributed to the interaction between the diffused hydrogen and growth of the martensitic domain.  相似文献

Fine-grained copper films on a flexible substrate were cyclically deformed under constant strain range control. It was found that cyclic dislocation plasticity through individual dislocation glide is still dominant at the submicrometer scale, while the ability of irreversible slip of dislocations gradually decreases and the damage was changed from extrusion-induced localization to cracking along grain boundary. Statistical evaluation of the mean spacing between slip bands and/or lines leads to a critical scale (~28 nm) below which dislocation-controlled cyclic strain localization would be shut down.  相似文献
