AbstractBackground Previous research indicates that work stress contributes to intentions to quit among direct care workers (DCWs) who provide services to people with intellectual and developmental disability (IDD). Though resources can help DCWs cope and remain in a job, little is known about how various dimensions of work stress and resources (social and personal resources) are associated with intentions to quit.Methods A total of 323 DCWs from 5 community-based IDD organisations completed a self-administered survey. We conducted multiple regression analyses to examine main and interaction effects of work stress and resources (work social support and internal locus of control) on intentions to quit.Results Work overload was a significant stressor, and work social support (i.e., supervisory support) was associated with low intentions to quit. The association between locus of control and intention to quit depended on the levels of a stressor: DCWs’ lack of participation in decision-making.Conclusions Supervisory support and an internal locus of control may assist DCWs in managing their stress. 相似文献

Health locus of control (HLOC) refers to beliefs regarding how one’s health is influenced by oneself, others, or fate. This meta-analysis investigated whether three HLOC dimensions (internality/I-HLOC, powerful others/P-HLOC, chance/C-HLOC) were related to both specific health behaviours and global health appraisal, and whether these relationships were moderated by gender and age compositions, individualism, and power distance. Three-level mixed-effects meta-analysis was performed on studies examining the associations of HLOC with specific health behaviour (k?=?76, N?=?76,580, 57% women, Mage?=?43.75) and global health appraisal (k?=?95, N?=?12,068, 57% women, Mage?=?45.44), respectively. For specific health behaviour, the averaged correlations with the HLOC dimensions were generally weak (r’s?=??.07 to .10). However, the links between P-HLOC and exercise were moderated by all four demographic moderators, and gender composition and individualism moderated the association between the HLOC dimensions and diet. For global health appraisal, all of the averaged correlations were statistically significant (r’s?=??.16 to .21), except that between P-HLOC and mental quality of life. The results further showed individualism and power distance to moderate the links between the HLOC dimensions and both mental and physical quality of life, and gender composition to moderate those between these dimensions and two indicators of emotional problems (depression and anxiety). 相似文献

Contamination by Staphylococcus aureus of the production environment of three small or medium-sized food-processing factories in Slovakia was investigated on the basis of sub-species molecular identification by multiple locus variable number of tandem repeats analysis (MLVA). On the basis of MLVA profiling, bacterial isolates were assigned to 31 groups. Data from repeated samplings over a period of 3 years facilitated to draw spatial and temporal maps of the contamination routes for individual factories, as well as identification of potential persistent strains. Information obtained by MLVA typing allowed to identify sources and routes of contamination and, subsequently, will allow to optimize the technical and sanitation measures to ensure hygiene. 相似文献

The main aim of this research is to explore the relationship between locus of control, self‐esteem and body dissatisfaction in the sample of university students, as well as the sex differences among the measures. The Body Shape Questionnaire (BSQ), Rosenberg Self‐Esteem Scale and the Externality Scale have been used on the sample of 534 female and 183 male university students. The results suggest that body dissatisfaction plays a more significant role in self‐esteem for girls than it does for boys. However, even the girls still have significantly lower BSQ results in comparison with female university students in the UK, and especially in the USA.

We demonstrate that the Y3/Y3** noncoding RNAs (ncRNAs) bind to the CPSF (cleavage and polyadenylation specificity factor) and that Y3** associates with the 3′ untranslated region (UTR) of histone pre-mRNAs. The depletion of Y3** impairs the 3′ end processing of histone pre-mRNAs as well as the formation and protein dynamics of histone locus bodies (HLBs), the site of histone mRNA synthesis and processing. HLB morphology is also disturbed by knockdown of the CPSF but not the U7-snRNP components. In conclusion, we propose that the Y3** ncRNA promotes the 3′ end processing of histone pre-mRNAs by enhancing the recruitment of the CPSF to histone pre-mRNAs at HLBs. 相似文献

Serving as one of our primary environmental inputs, vision is the most sophisticated sensory system in humans. Here, we present recent findings derived from energetics, genetics and physiology that provide a more advanced understanding of color perception in mammals. Energetics of cis–trans isomerization of 11-cis-retinal accounts for color perception in the narrow region of the electromagnetic spectrum and how human eyes can absorb light in the near infrared (IR) range. Structural homology models of visual pigments reveal complex interactions of the protein moieties with the light sensitive chromophore 11-cis-retinal and that certain color blinding mutations impair secondary structural elements of these G protein-coupled receptors (GPCRs). Finally, we identify unsolved critical aspects of color tuning that require future investigation. 相似文献
