L'étude porte sur l'exercice de la liberté syndicale et du droit de négociation collective dans l'économie des plateformes. Après avoir commenté plusieurs exemples de mobilisation collective des travailleurs des plateformes dans le monde, l'auteur plaide pour l'adoption d'une approche axée sur les droits de l'homme de ces deux garanties, que divers instruments internationaux consacrent, et que de nombreux tribunaux nationaux et internationaux ont utilisées pour justifier leurs décisions. C'est pour lui la seule façon de protéger tous les travailleurs, indépendamment de leur situation au regard de l'emploi, dans un monde du travail en mutation. 相似文献

A growing body of leadership literature focuses on leader and follower identity dynamics, levels, processes of development and outcomes. Despite the importance of the phenomena, there has been surprisingly little effort to systematically review the widely dispersed literature on leader and follower identity. In this review we map existing studies on a multilevel framework that integrates levels-of-the self (individual, relational and collective) with the levels-of-analysis (intrapersonal, interpersonal and group) on which leader or follower identity work takes place. We also synthesize work from multiple research paradigms, such as social psychology experimental studies, narrative accounts of leaders' identity work and field studies on antecedents, outcomes, mediating mechanisms and boundary conditions. Finally, we outline implications for leadership development and call attention to key themes we see ripe for future research. 相似文献

Although the literature concerning the association between religiosity and fertility in European countries is already quite extensive, studies exploring the mechanisms of action of religiosity are rare. The main aim of this article is to investigate whether grandparental childcare is a mediating or moderating variable in the association between attendance at religious services and the intention to have a second or third child. Building on previous literature, we assume that parents who are more religious might put more effort into establishing a positive relation with the grandparents of their child/children. Consequently, compared to parents who are less religious, those who are more religious could be more receptive to possible encouragement from grandparents to have another child and may be more optimistic regarding grandparents’ involvement with an additional child. Using Generations and Gender Survey (GGS) data for eleven European countries, we find evidence of a strong and positive effect of attendance at religious services on fertility intentions. Receipt of regular or weekly help from grandparents positively moderates the association between attendance at religious services and fertility intentions, albeit only for male respondents and mainly for the intention to have a second child. 相似文献

This study aimed to investigate the degree to which the elements of the theory of planned behavior mediate the relationship
between constraints and intention to continuing participation in physical activities. The sample of the study consisted of
119 (N = 119) older individuals who participated in organized physical activity programs. The results indicated that attitudes and
perceived behavioral control were negatively correlated with constraints, whereas the subjective norm variable had no relationship
with them. In terms of the mediation role of the elements of the theory of planned behavior, the results indicated that both
attitudes and perceived behavioral control partially mediated the relationship between constraints and intention, with the
perceived behavioral control variable being the strongest mediator. These findings suggest that the theory of planned behavior
elements mediate the constraints–intention relationship and determine, in a large degree, the older individuals’ intention
to continuing taking part in physical activities. 相似文献

COM-Poisson regression is an increasingly popular model for count data. Its main advantage is that it permits to model separately the mean and the variance of the counts, thus allowing the same covariate to affect in different ways the average level and the variability of the response variable. A key limiting factor to the use of the COM-Poisson distribution is the calculation of the normalisation constant: its accurate evaluation can be time-consuming and is not always feasible. We circumvent this problem, in the context of estimating a Bayesian COM-Poisson regression, by resorting to the exchange algorithm, an MCMC method applicable to situations where the sampling model (likelihood) can only be computed up to a normalisation constant. The algorithm requires to draw from the sampling model, which in the case of the COM-Poisson distribution can be done efficiently using rejection sampling. We illustrate the method and the benefits of using a Bayesian COM-Poisson regression model, through a simulation and two real-world data sets with different levels of dispersion. 相似文献

This paper examines the exercise of the rights to freedom of association and collective bargaining by platform workers. It focuses on several significant developments involving the collective organization of platform workers worldwide, and considers the rights to freedom of association and collective bargaining as human rights. It contends that the shifting context of work has led to changes in modern workplaces, which, in turn, have generated a novel interest in the adoption of a human rights-based approach towards labour protection. This approach considers that all workers are entitled to rights, such as the right to collective bargaining, which derive from international human rights instruments. 相似文献
