Civil societies are usually seen as facilitators of democracy or as oppositional powers withstanding authoritarian rule. However, more and more often civil society organizations (CSOs) appear to contribute to the legitimacy of non-democratic incumbents. Taking the example of contemporary Russia, this paper argues that state funding for CSOs under authoritarian regime conditions serves for securing regime legitimacy in two respects—by supporting CSOs contribution to public welfare and by transmitting state-led legitimacy discourse to the civil society sector. The analysis of applications submitted between 2013 and 2016 to the Presidential Grant Competition (PGC), the biggest public funding programme for CSOs in Russia, shows that the state is (1) supporting CSO activities above all in social, health and education-related fields, and (2) privileging projects that relate to a state-led conservative public discourse not only but foremost within those welfare-related fields. These results highlight the importance of investigating state support to CSOs in order to access the changing role of civil society under authoritarian regime conditions.

In both adolescents and adults, gambling problems and depressive symptoms co-occur and share some common risk factors (e.g., impulsivity and socio-family risk). However, little is known about (1) the developmental course of the co-morbidity of these problems; (2) variables that may moderate the effect of these common risk factors on gambling problems and depressive symptoms. Of specific interest could be individuals’ social relationships with significant others such as parents and friends, because research shows that they moderate the effect of other risk factors on gambling problems and depressive symptoms. The goals of this study were to: (a) identify developmental pathways for gambling problems and depressive symptoms, with a focus on co-morbidity; (b) assess the moderating effect of relationship quality with parents and friends on the link between common risk factors and the trajectories of gambling problems and depressive symptoms. Study participants were 878 males. Predictors were assessed during childhood and adolescence and gambling problems and depressive symptoms were assessed in late adolescence and young adulthood. Latent class analysis revealed four distinct joint trajectories of gambling problems and depressive symptoms. Subsequent logistic regression revealed that impulsivity predicted membership in all pathogenic trajectories, and quality of the relationship with parents predicted membership in depressogenic trajectories. In addition, we found that the membership in the comorbid trajectory can be predicted by an interaction between friendship quality and socio-family risk.  相似文献

The objective of this work was to summarise and evaluate the evidence showing that physical activity is a protector factor as regards falls in older people. Relevant studies were identified through a systematic search in the MEDLINE and Cochrane Library, under the keywords of accidental fall/numerical data and risk factors, and with the bibliographies of retrieved papers. The combined odds ratio (OR) [95% confidence interval] for physical activity was 0.75 [0.64, 0.88] with moderate heterogeneity (I 2?=?33%). For fall injury, it was 0.59 [0.47, 0.74] and, for falls in general, it rose to 0.94 [0.76, 1.17] with nil heterogeneity. The combined OR for sedentary factors was 1.14 [1.10, 1.82] with moderate heterogeneity (I 2?=?36%). Regular physical activity in daily life yields significant reduction in falls in older people, especially falls with injuries.  相似文献

We estimate two well-known risk measures, the value-at-risk (VAR) and the expected shortfall, conditionally to a functional variable (i.e., a random variable valued in some semi(pseudo)-metric space). We use nonparametric kernel estimation for constructing estimators of these quantities, under general dependence conditions. Theoretical properties are stated whereas practical aspects are illustrated on simulated data: nonlinear functional and GARCH(1,1) models. Some ideas on bandwidth selection using bootstrap are introduced. Finally, an empirical example is given through data of the S&P 500 time series.  相似文献

In a missing-data setting, we want to estimate the mean of a scalar outcome, based on a sample in which an explanatory variable is observed for every subject while responses are missing by happenstance for some of them. We consider two kinds of estimates of the mean response when the explanatory variable is functional. One is based on the average of the predicted values and the second one is a functional adaptation of the Horvitz–Thompson estimator. We show that the infinite dimensionality of the problem does not affect the rates of convergence by stating that the estimates are root-n consistent, under missing at random (MAR) assumption. These asymptotic features are completed by simulated experiments illustrating the easiness of implementation and the good behaviour on finite sample sizes of the method. This is the first paper emphasizing that the insensitiveness of averaged estimates, well known in multivariate non-parametric statistics, remains true for an infinite-dimensional covariable. In this sense, this work opens the way for various other results of this kind in functional data analysis.  相似文献

This article is a critical survey of a field of research that for 20 years has been particularly active in France and is once again gaining momentum: the sociology of activist commitment. An outcome of this sociological current was the inter-actionist paradigm, i.e. how activists’ careers are embarked upon and evolve. The notion of how to reward activism has been refined and reconsidered. Theoretical debates relating to the surfacing – or not – of “new forms” of activism – or even “new activists” – are replaced in perspective and the two challenges that confront research today stressed. Both concern the social division of labor: how to account more thoroughly for the link between macro-social transformations and individual commitment, on one hand, how organizations are instrumental in formatting activism, on the other.  相似文献

We show that the capability approach can greatly facilitate ex ante policy evaluations, in particular those that are geared towards multiple goals. It enables a structured discussion on policy benefits, distributional issues, freedom and ethics. We illustrate our general ideas with a real-world application: the impact assessment of an EU-proposal on organ donation.  相似文献

This article shows that if an allocation rule can be implemented with unlimited information certification, then it can also be implemented with limited information certification if the designer can use ambiguous communication mechanisms, and if agents are averse to ambiguity in the sense of maxmin expected utility. The reverse implication is true if there is a single agent and a worst outcome.  相似文献
