The relationship between presenteeism and job satisfaction: A mediated moderation model using work engagement and perceived organizational support

Research on presenteeism has largely focused on its prevalence, determinants and consequences on the health of both employees and organizations. To date, few studies have examined the influence of presenteeism on workers’ attitudinal and motivational responses. Based on the Effort–Recovery Theory, this study evaluates the mediating effect of work engagement in the relationship between presenteeism and job satisfaction. Building on previous work, this study also proposes to consider perceived organizational support as a moderator of the work engagement–job satisfaction relationship. Presented in the form of a mediated moderation model, the results of bootstrapped regression analyses show three main results. First, presenteeism is negatively associated with work engagement and job satisfaction. Secondly, work engagement is one of the factors through which presenteeism influences job satisfaction. Thirdly, perceived organizational support moderates the association between work engagement and job satisfaction so that, at a low level of work engagement, feeling supported by the organization makes a difference on job satisfaction. Overall, this research is part of the limited number of studies that have focused on the interplay existing between presenteeism and its consequences in terms of job attitudes.     

Semi-parametric segmentation of multiple series using a DP-Lasso strategy

We consider a semi-parametric approach to perform the joint segmentation of multiple series sharing a common functional part. We propose an iterative procedure based on Dynamic Programming for the segmentation part and Lasso estimators for the functional part. Our Lasso procedure, based on the dictionary approach, allows us to both estimate smooth functions and functions with local irregularity, which permits more flexibility than previous proposed methods. This yields to a better estimation of the functional part and improvements in the segmentation. The performance of our method is assessed using simulated data and real data from agriculture and geodetic studies. Our estimation procedure results to be a reliable tool to detect changes and to obtain an interpretable estimation of the functional part of the model in terms of known functions.     

The effect of hours of work on social interaction

Increases in hours of work per capita over past 30?years have created an intuitively plausible notion that there now is less time for social interaction. The purpose of this paper is to empirically investigate the effect of hours of work on social interaction. The empirical work is complicated by the argument that unobserved factors could increase both hours of work and social interaction. The empirical work in this paper employs an exogenous decline in hours of work in France due to a new employment law to bypass this endogeneity problem. The data employed are derived from the 1999?C2003 Continuous Survey of Household Living Conditions which is a random sample of French households. Gender specific results from a difference-in-difference model show that the employment laws reduced hours of work but there is no evidence that the extra hours went to increased social interactions. Contrary to the intuitive argument, the paper concludes that in the range of approximately 94 extra hours of leisure per year, hours of work have no effect on social interaction.     

Preschoolers' Attachment to Mother and Risk for Adjustment Problems in Kindergarten: Can Teachers Make a Difference?

Based on attachment theory, two aims were addressed. Firstly, we tested whether close teacher–child relationships may buffer children who are less securely attached to their mothers against negative outcomes, such as aggressive behavior. Secondly, our study evaluated whether teacher sensitivity may protect less securely attached children against forming less close relationships with their teachers. In a sample of 127 children, mother–child attachment was observed in preschool. In kindergarten, teacher sensitivity was observed, and teacher–child closeness and child aggressive behavior were rated by the teacher. Results of multilevel hierarchical regression analyses first showed that with high teacher–child closeness, less securely attached children are no longer at risk for more aggressive behavior. Secondly, it was found that with high teacher sensitivity, less securely attached children are no longer at risk for developing less close relationships with their teachers.     

Involvement of Ministries of Health in Health Service Coverage Decisions: Is England an Aberrant Case?

This article examines the involvement of ministries of health in making health service coverage decisions in Denmark, England, France and Germany. The study aims to inform debate in England about the feasibility of reducing perceived ministerial and bureaucratic ‘interference’ in decisions affecting the National Health Service, based on interviews with senior government officials and other health system stakeholders. Ministries of health differ in their involvement in health system governance and coverage decisions (‘the benefits package’), reflecting differences in institutional arrangements. In all four countries, organizations at arm's length or independent from government are either involved in providing technical advice to the ministry of health or have been mandated to take these decisions themselves. However, ministries of health occasionally intervene in the decision‐making process or ignore the advice of these organizations. The Department of Health in England is not an aberrant case, at least in relation to coverage decisions. Indeed, ministries of health in Denmark and France play a larger role in making these decisions. Public pressure, often amplified by the media, is a shared reason for ministerial and ministry involvement in all four countries. This dynamic may thus limit the feasibility of attempts to further separate the NHS from both the Department of Health and wider political pressures.     

Children’s Recognition and Discrimination of Fear and Disgust Facial Expressions

Facial expressions of fear and disgust have repeatedly been found to be less well recognized than those of other basic emotions by children. We undertook two studies in which we investigated the recognition and visual discrimination of these expressions in school-age children. In Study 1, children (5, 6, 9, and 10 years of age) were shown pairs of facial expressions, and asked to tell which one depicted a target emotion. The results indicated that accuracy in 9- and 10-year-olds was higher than in 5- and 6-year-olds for three contrasts: disgust–anger, fear–surprise, and fear–sadness. Younger children had more difficulty recognizing disgust when it was presented along with anger, and in recognizing fear when it was presented along with surprise. In Study 2, children (5, 6, 9, and 10 years of age) were shown a target expression along with two other expressions, and were asked to point to the expression that was the most similar to the target. Contrary to our expectations, even 5- and 6-year-olds were very accurate in discriminating fear and disgust from the other emotions, suggesting that visual perception was not the main limiting factor for the recognition of these emotions in school-age children.     

High Sex Ratios at Birth in the Caucasus: Modern Technology to Satisfy Old Desires

During the 1990s, the sex ratio at birth increased considerably and simultaneously in the three independent Caucasian countries, Armenia, Azerbaijan, and Georgia. At the end of the first decade of the twenty‐first century, levels remain abnormally high in Armenia and Azerbaijan (above 114 male births per 100 female births) and show erratic trends in Georgia. Analyzing data from demographic surveys carried out around 2005, we confirm the persistence of high sex ratios in these three countries and document significant differences in fertility intentions and behavior according to the sex of the previous child or children that constitute evidence of the practice of sex‐selective abortion. These countries combine societal features and medical systems that make this phenomenon possible: son preference in a context of low fertility and the possibility of prenatal sex selection given easy access to ultrasound screening and induced abortion. Why high sex ratios are observed only in these three countries of the sub‐region remains, however, an open question.     

SIRALINA: efficient two-steps heuristic for storage optimisation in single period task scheduling

In this paper, we study the general problem of one-dimensional periodic task scheduling under storage requirement, irrespective of machine constraints. We have already presented in (Touati and Eisenbeis, Parallel Process. Lett. 14(2):287–313, 2004) a theoretical framework that allows an optimal optimisation of periodic storage requirement in a cyclic schedule. Since our optimisation problem is NP-hard (Touati, PhD thesis, 2002), solving an exact integer linear programming formulation is too expensive in practice. In this article, we propose an efficient two-steps heuristic using model’s properties that allows fast computation times while providing highly satisfactory results. This method includes the solution of an integer linear program with a totally unimodular constraints matrix in first step, then the solution of a linear assignment problem. Our heuristic is implemented for an industrial compiler for embedded VLIW processors.     

Adolescents' Career Decision‐Making Process: Related to Quality of Attachment to Parents?

This longitudinal study examined how adolescents' perceptions of attachment security with parents relate to their process of choosing a major in higher education. The participants were 281 students who were investigated at the beginning, middle, and end of Grade 12. Findings showed that higher perceived security with mother, but not with father, predicted higher levels of coping with the career decisional tasks of orientation, broad and in‐depth environmental exploration, and self‐exploration in the future. However, perceived security did not relate to the degree of change in decisional tasks during Grade 12. Finally, results suggested that the association between perceived security with mother and the decisional tasks of orientation, broad and in‐depth environmental exploration, and self‐exploration was mediated by adolescents' career decision‐making self‐efficacy.     

Social mobilizations and the question of social justice in contemporary Russia

ABSTRACT

Notwithstanding stereotypes of Russian apathy, long-term field research reveals that there have always been grassroots and labour protests in post-Soviet Russia, even as the shock of ultraliberal reforms led to mass precariousness and social disorientation. However, the social mobilizations that do occur are scattered, weakly publicized and mostly small-scale. This paper conceptualizes them as ‘everyday activism’, that is, an activism embedded in everyday life experience and pragmatic sense. Only recently, and in a paradoxical relation to the populist and patriotic Kremlin discourse, some new trends have emerged towards other popular variants of the new discourse that includes social equality claims and what the paper calls ‘social critical’ populism. However, this populism from below does not automatically lead to mass mobilization, although it provides the necessary background for it.
