Precarious Work: Agenda and Implications for Corporate Social Responsibility

Precarious work, in contrast to regular, permanent wage work, is commonly associated to insecure and unstable, and often poor quality jobs. The concept of precarious work relates either to a socioeconomic group which allows one to refer it to a "class in itself," or as - pursued more recently - to the precarization process which results in a growing fragmentation of societal structures. Common to both conceptions is that they refer to the exposition of workers to employment instability, limited access to legal and union protection, socially irresponsible and discriminating employment practices, and social and economic vulnerability in general. The present contribution provides an overview of some key issues and future directions of research on precarious work relevant to CSR researchers, policy-makers, and social scientists.

Gender, family and employment in comparative perspective: the realities and representations of rqual rpportunities in Britain and France

In this paper, we will explore how contrasting national discourses relating to women, and gender equality have been incorporated into and reflected in national policies. In the first section, we will outline the recent history of EU equal opportunities policy, in which positive action has been replaced by a policy of 'mainstreaming'. Second, we will describe the evolution of policies towards women and equal opportunities in Britain and France. It will be argued that whereas some degree of positive action for women has been accepted in Britain, this policy is somewhat alien to French thinking about equality - although pro-natalist French policies have resulted in favourable conditions for employed mothers in France. In the third section, we will present some attitudinal evidence, drawn from national surveys, which would appear to reflect the national policy differences we have identified in respect of the 'equality agenda'. In the fourth section, we will draw upon biographical interviews carried out with men and women in British and French banks in order to illustrate the impact of these cross-national differences within organizations and on individual lives. We demonstrate that positive action gender equality policies have made an important impact in British banks, while overt gender exclusionary practices still persist in the French banks studied. In the conclusion, we reflect on the European policy implications of our findings.

Secretory IgA-mediated neutralization of Shigella flexneri prevents intestinal tissue destruction by down-regulating inflammatory circuits.

Shigella, a Gram-negative invasive enteropathogenic bacterium responsible for bacillary dysentery, causes the rupture, invasion, and inflammatory destruction of the human colonic mucosa. We explored the mechanisms of protection mediated by Shigella LPS-specific secretory IgA (SIgA), the major mucosal Ab induced upon natural infection. Bacteria, SIgA, or SIgA-S. flexneri immune complexes were administered into rabbit ligated intestinal loops containing a Peyer's patch. After 8 h, localizations of bacteria, SIgA, and SIgA-S. flexneri immune complexes were examined by immunohistochemistry and confocal microscopy imaging. We found that anti-Shigella LPS SIgA, mainly via immune exclusion, prevented Shigella-induced inflammation responsible for the destruction of the intestinal barrier. Besides this luminal trapping, a small proportion of SIgA-S. flexneri immune complexes were shown to enter the rabbit Peyer's patch and were internalized by dendritic cells of the subepithelial dome region. Local inflammatory status was analyzed by quantitative RT-PCR using newly designed primers for rabbit pro- and anti-inflammatory mediator genes. In Peyer's patches exposed to immune complexes, limited up-regulation of the expression of proinflammatory genes, including TNF-alpha, IL-6, Cox-2, and IFN-gamma, was observed, consistent with preserved morphology. In contrast, in Peyer's patches exposed to Shigella alone, high expression of the same mediators was measured, indicating that neutralizing SIgA dampens the proinflammatory properties of Shigella. These results show that in the form of immune complexes, SIgA guarantees both immune exclusion and neutralization of translocated bacteria, thus preserving the intestinal barrier integrity by preventing bacterial-induced inflammation. These findings add to the multiple facets of the noninflammatory properties of SIgA.

Not in Education, Employment, or Training status among young Swiss men. Longitudinal associations with mental health and substance use.

PURPOSE: Not in Education, Employment, or Training (NEET) youth are youth disengaged from major social institutions and constitute a worrying concern. However, little is known about this subgroup of vulnerable youth. This study aimed to examine if NEET youth differ from other contemporaries in terms of personality, mental health, and substance use and to provide longitudinal examination of NEET status, testing its stability and prospective pathways with mental health and substance use. METHODS: As part of the Cohort Study on Substance Use Risk Factors, 4,758 young Swiss men in their early 20s answered questions concerning their current professional and educational status, personality, substance use, and symptomatology related to mental health. Descriptive statistics, generalized linear models for cross-sectional comparisons, and cross-lagged panel models for longitudinal associations were computed. RESULTS: NEET youth were 6.1% at baseline and 7.4% at follow-up with 1.4% being NEET at both time points. Comparisons between NEET and non-NEET youth showed significant differences in substance use and depressive symptoms only. Longitudinal associations showed that previous mental health, cannabis use, and daily smoking increased the likelihood of being NEET. Reverse causal paths were nonsignificant. CONCLUSIONS: NEET status seemed to be unlikely and transient among young Swiss men, associated with differences in mental health and substance use but not in personality. Causal paths presented NEET status as a consequence of mental health and substance use rather than a cause. Additionally, this study confirmed that cannabis use and daily smoking are public health problems. Prevention programs need to focus on these vulnerable youth to avoid them being disengaged.

FGF receptors control vitamin D and phosphate homeostasis by mediating renal FGF-23 signaling and regulating FGF-23 expression in bone.

The functional interaction between fibroblast growth factor 23 (FGF-23) and Klotho in the control of vitamin D and phosphate homeostasis is manifested by the largely overlapping phenotypes of Fgf23- and Klotho-deficient mouse models. However, to date, targeted inactivation of FGF receptors (FGFRs) has not provided clear evidence for an analogous function of FGFRs in this process. Here, by means of pharmacologic inhibition of FGFRs, we demonstrate their involvement in renal FGF-23/Klotho signaling and elicit their role in the control of phosphate and vitamin D homeostasis. Specifically, FGFR loss of function counteracts renal FGF-23/Klotho signaling, leading to deregulation of Cyp27b1 and Cyp24a1 and the induction of hypervitaminosis D and hyperphosphatemia. In turn, this initiates a feedback response leading to high serum levels of FGF-23. Further, we show that FGFR inhibition blocks Fgf23 transcription in bone and that this is dominant over vitamin D-induced Fgf23 expression, ultimately impinging on systemic FGF-23 protein levels. Additionally, we identify Fgf23 as a specific target gene of FGF signaling in vitro. Thus, in line with Fgf23- and Klotho-deficient mouse models, our study illustrates the essential function of FGFRs in the regulation of vitamin D and phosphate levels. Further, we reveal FGFR signaling as a novel in vivo control mechanism for Fgf23 expression in bone, suggesting a dual function of FGFRs in the FGF-23/Klotho pathway leading to vitamin D and phosphate homeostasis.

Two alpha1-adrenergic receptor subtypes regulating the vasopressor response have differential roles in blood pressure regulation.

To study the functional role of individual alpha1-adrenergic (AR) subtypes in blood pressure (BP) regulation, we used mice lacking the alpha1B-AR and/or alpha1D-AR with the same genetic background and further studied their hemodynamic and vasoconstrictive responses. Both the alpha1D-AR knockout and alpha1B-/alpha1D-AR double knockout mice, but not the alpha1B-AR knockout mice, had significantly (p < 0.05) lower levels of basal systolic and mean arterial BP than wild-type mice in nonanesthetized condition, and they showed no significant change in heart rate or in cardiac function, as assessed by echocardiogram. All mutants showed a significantly (p < 0.05) reduced catecholamine-induced pressor and vasoconstriction responses. It is noteworthy that the infusion of norepinephrine did not elicit any pressor response at all in alpha1B-/alpha1D-AR double knockout mice. In an attempt to further examine alpha1-AR subtype, which is involved in the genesis or maintenance of hypertension, BP after salt loading was monitored by tail-cuff readings and confirmed at the endpoint by direct intra-arterial recording. After salt loading, alpha1B-AR knockout mice developed a comparable level of hypertension to wild-type mice, whereas mice lacking alpha1D-AR had significantly (p < 0.05) attenuated BP and lower levels of circulating catecholamines. Our data indicated that alpha1B- and alpha1D-AR subtypes participate cooperatively in BP regulation; however, the deletion of the functional alpha1D-AR, not alpha1B-AR, leads to an antihypertensive effect. The study shows differential contributions of alpha1B- and alpha1D-ARs in BP regulation.

Introduction to the special issue on employment discrimination against immigrants

Purpose - This editorial aims to introduce the special issue on employment discrimination against immigrants. Design/methodology/approach - The first part is a commentary on key issues in the study of employment discrimination against immigrants. The second part presents the five articles in the special issue. Findings - The papers in this special issue focus on a variety of issues associated with employment discrimination against immigrants. For example, they consider: discrimination based on accents; differences among justice perceptions among immigrants and non-immigrants; the effects of negative stereotypes on workplace outcomes; the treatment of Hispanic immigrants; and the reasons for the lack of research on Hispanic immigrants. Research limitations/implications - The author comments on key issues that researchers of employment discrimination against immigrants have to take into account. These issues include: the appreciation of the diversity among immigrants; an understanding of the complexity of employment discrimination research; openness to cross-disciplinary approaches; and the consideration of employment discrimination within the context of the immigrant experience. The five articles that make up the special issues vary in their nature (empirical, critical), methodologies (quantitative, qualitative), locations (United States, Germany, and Canada), and implications. Practical implications - The issues discussed in the papers have important implications for understanding and overcoming employment discrimination against immigrants. Originality/value - The Journal of Managerial Psychology invited this special issue to initiate psychological research on employment discrimination against immigrants. The intent is to draw the attention of organizational scholars to the large, yet under-studied immigrant segment of the workforce.
