Self-determination theory's distinction between extrinsic and intrinsic goal pursuits offers a possible explanation for ethnic and racial prejudice. Because extrinsic relative to intrinsic goal pursuits (E/I) stimulate interpersonal competition, they were expected to predict social dominance orientation (SDO), which, in turn, would predict racial and ethnic(More)
In the present study we contrast materialistic (i.e., income and economic inequality) and psychosocial (i.e., social circumstances) pathway perspectives on whether volunteering while being unemployed mitigates the well-documented negative effects of unemployment on health, health behaviors, and well-being. We test our hypotheses using data from the 2010 and(More)
PURPOSE Research has provided convincing evidence for the adverse effects of both short- and long-term unemployment, and perceived job insecurity on individuals' health and well-being. This study aims to go one critical step further by comparing the association between short- and long-term unemployment, and perceived job insecurity with a diverse set of(More)
In this study, we first explore whether different exposure groups of workplace bullying exist, employing a large, heterogeneous sample. The results show six different exposure groups: almost 30.5% is not bullied since they report hardly any negative act at work at all, 27.2% face some limited work criticism, 20.8% face limited negative encounters, 8.3% is(More)
This study investigates how job insecurity and employability relate to job satisfaction and affective organizational commitment in permanent workers, fixed-term contract workers, and temporary agency workers. The authors hypothesized that (a) job insecurity relates negatively to job satisfaction and affective organizational commitment, and this relationship(More)
Dramatic changes in workplace structure and environment have increased the importance of psychosocial factors and job insecurity in working life. Job insecurity is shown to have a negative impact on mental and physical health. Health care transformation in Turkey increases the threat of job insecurity for many workers in the health care sector. Therefore(More)
OBJECTIVE The aim of this study was to gain insight in the importance of job demands and resources and the validity of the Job Demands Resources Model across sectors. METHODS We used one-way analyses of variance to examine mean differences, and multi-group Structural Equation Modeling analyses to test the strength of the relationships among job demands,(More)
This study aims to further knowledge on the mechanisms through which job insecurity is related to negative outcomes. Based on appraisal theory, two explanations-perceived control and psychological contract breach-were theoretically integrated in a comprehensive model and simultaneously examined as mediators of the job insecurity-outcome relationship.(More)
There is strong circumstantial evidence that certain heavy, unstable atomic nuclei are 'octupole deformed', that is, distorted into a pear shape. This contrasts with the more prevalent rugby-ball shape of nuclei with reflection-symmetric, quadrupole deformations. The elusive octupole deformed nuclei are of importance for nuclear structure theory, and also(More)
Fast-neutron-induced fission of ^{238}U at an energy just above the fission threshold is studied with a novel technique which involves the coupling of a high-efficiency γ-ray spectrometer (MINIBALL) to an inverse-kinematics neutron source (LICORNE) to extract charge yields of fission fragments via γ-γ coincidence spectroscopy. Experimental data and fission(More)
