This study assesses the combined impact of multiple certifications (i.e. ISO 9001, ISO 14001, OHSAS 18001) on perceived performance dimensions related to quality, environmental and occupational health and safety. Using survey data collected from 59 Irish manufacturing plants in 2014, we employed MANCOVA and regression analysis to test our proposed hypothesis. The results suggest that companies that are simultaneously ISO 9001, ISO 14001 and OHSAS 18001 certified are significantly better performers with regard to environmental and occupational health and safety compared to companies without multiple certifications. However, from a perceived quality performance perspective, having these multiple certifications doesn’t seem to be an effective performance improvement tool. 相似文献

Summary. A general method for exploring multivariate data by comparing different estimates of multivariate scatter is presented. The method is based on the eigenvalue–eigenvector decomposition of one scatter matrix relative to another. In particular, it is shown that the eigenvectors can be used to generate an affine invariant co-ordinate system for the multivariate data. Consequently, we view this method as a method for invariant co-ordinate selection . By plotting the data with respect to this new invariant co-ordinate system, various data structures can be revealed. For example, under certain independent components models, it is shown that the invariant co- ordinates correspond to the independent components. Another example pertains to mixtures of elliptical distributions. In this case, it is shown that a subset of the invariant co-ordinates corresponds to Fisher's linear discriminant subspace, even though the class identifications of the data points are unknown. Some illustrative examples are given. 相似文献

Based on a sample of older workers from the Maastricht Cohort Study, the authors investigate the prevalence and dynamics of self‐reported under‐skilling and its effects on workers' need for recovery, their risk of losing employment and their retirement intentions over a two‐year period. They find that being under‐skilled is associated both with higher levels of need for recovery over time and with the risk of losing employment, but not with early retirement intentions. To achieve sustainable employment, they argue, the course of under‐skilling should be monitored throughout workers' careers, enabling timely interventions to avoid its negative consequences. 相似文献

As adolescents move into emerging adulthood, their social networks shift toward a focus on peers and romantic partners, yet parents and siblings remain important sources of support. The present review takes a family systems approach to integrate the growing body of literature examining longitudinal continuity and change in both positive (e.g., intimacy, support) and negative (e.g., conflict, rivalry) qualities of parent–child and sibling relationships as adolescents transition to emerging adulthood. In general, contact with family members decreases, yet the quality of family relationships appears to improve or, at the very least, stabilize across this transition. These pathways are interpreted within the lens of several prominent theories, and a discussion of the limitations of the current literature and ideas for future research are presented. 相似文献

Research on timing of parental remarriage is important to understanding consequences of remarriage for children. In this study, survival analyses were conducted predicting timing of parental remarriage from parental loss in a sample of 3,774 offspring whose parents divorced or whose mother or father died during childhood. Transition to remarriage was quicker for parents who divorced compared to those who were widowed, especially for fathers. By examining timing of remarriage from the perspective of parents, and thus children, we identify not only who is more likely to experience parental remarriage, but when remarriage is likely to occur. 相似文献

This study examined whether social contagion of anxiety symptoms is present between siblings during early adolescence and whether this process is moderated by sex, relationship quality, and zygosity. Based on 634 monozygotic and dizygotic twins (336 females) assessed in Grades 6 and 7, anxiety symptoms and sibling relationship quality were measured with self‐report questionnaires. The predictive association of the co‐twin's level of anxiety with adolescents' own increased anxiety 1 year later was only observed in same‐sex twin dyads (monozygotic and dizygotic) and was higher for those who perceived a higher level of relationship quality with their co‐twin. Raising awareness of a possible sibling contagion of anxiety may be useful for preventing the development of anxiety symptoms in youth. 相似文献

ABSTRACTDementia has been identified as a global challenge across the spectrum of health and social care (World Health Organisation. (2012) Dementia: A public health priority. Geneva: WHO). This paper will explore the implications of this for social work education and the challenges it poses. There is a lack of this focus on social work with older people and people with dementia (pwd) in social work education. Based on calls for an infusion of content on ageing and dementia in social work curricula, paper proposes that we should adopt a person-centred philosophy alongside gerontological social work competencies to achieve this. The specific aim of this paper, therefore, is to explore how we can use these ideas as teaching tools to engage social work students in the discourse on dementia and to develop appropriate skills to work with pwd, their families and carers. 相似文献

ABSTRACTDespite increasing societal acceptance of sexual-minority individuals, there are still gay, lesbian, and bisexual (GLB) adolescents who experience negative mental health outcomes. Minority stress theory posits that stigma-related stress associated with sexual-minority status drives increased risk among GLB individuals. Furthermore, recent evidence suggests that minority stress impacts emotion regulation (ER), identified as a particularly important risk factor for sexual-minority youth (SMY). Current research has identified some aspects of parenting contribute to GLB youth's mental health. We review the literature in these areas, and also integrate research from the broader developmental field on families and emotion socialization in order to identify the need for studies of parenting that go beyond existing data on parental acceptance and supportiveness of youth's sexual orientation. Limitations of the current literature and directions for future research are discussed, with specific focus on implications for interventions with SMY and their families. 相似文献
