Dans cette étude, nous examinons les répercussions sociales de la mondialisation dans une perspective culturelle. Notre analyse porte sur le conflit qui existe entre le discours sur la mondialisation et les priorités locales, entre les droits de l'individu et les engagements des pouvoirs publics ainsi que sur la difficulté de trouver de nouveaux points d'ancrage de l'identité culturelle dans un contexte où les frontières territoriales entre les États s'effacent et où les idées de progres, de modernité et d'évolution se sont érodées. Ces traits accompagnent la transformation amorcée dans le cadre des relations complexes et hégémoniques qui caractérisent aujourd'hui le système mondial. Ce conflit et ces problèmes demeurent un axe fondamental du débat politique. Nous suggérons que les différentes formes de participation se traduisent de diverses façons dans le champ de l'expression politique et dans Interprétation des exigences sociales et des droits, et influent sur la vie publique à la veille du XXIesiécle. This article explores the social implications of globalization as cultural vision. Discussion bears upon the tension between the discourse of globality and local priorities, of individual rights and public commitments, and upon the problems of finding new ways for grounding identities as territorial state boundaries are weakened and the ideas of progress, modernity and evolutionary perspectives are eroded as part of a process of change initiated in the developed and hegemonic settings of the world system. It is claimed that these tensions and problems remain a crucial axis of political debate. It is suggested that different patterns of participation meld in manifold ways into recreated forms of political will and varied interpretations of social claims on and rights to affect the shaping of public life at the turn of the century. 相似文献

In the presence of covariate information, the proportional hazards model is one of the most popular models. In this paper,
in a Bayesian nonparametric framework, we use a Markov (Lévy-driven) process to model the baseline hazard rate. Previous Bayesian
nonparametric models have been based on neutral to the right processes, which have a number of drawbacks, such as discreteness
of the cumulative hazard function. We allow the covariates to be time dependent functions and develop a full posterior analysis
via substitution sampling. A detailed illustration is presented. 相似文献

Low back pain is a costly and incapacitating musculoskeletal disorder. Prospective studies documenting the capacity of work-related factors to predict chronicity are few in number, the methodology used is very diversified, and the results obtained diverge. The aim of the present study is to investigate the capacity of work-related objective (non-psychosocial) and psychosocial factors to predict chronic disability related to low back pain. A longitudinal prospective study with two measurement times was carried out. The sample (N = 258) consisted of workers with subacute low back pain who were on sick leave and receiving compensation from the CSST (Quebec Workers' Compensation Board). Of all the work-related variables measured, perceived stress and fears and beliefs about work were associated with return to work status at the six-month follow-up. The results obtained show the importance of considering fears and beliefs about work when identifying people in the subacute phase of low back pain who are at risk of developing chronic disability. 相似文献

Collective and Unitary Models: A Clarification 总被引:3,自引:0,他引:3

In this note we identify and clarify a confusion that has arisen in the literature about the exact relationship between unitary
and collective models and what enters the Pareto weight and the sharing function. We suggest that we should denote as ‘unitary’
any model that leads to outcomes that satisfy the Slutsky conditions whether or not these outcomes depend on distribution
factors. In particular, income pooling is neither necessary nor sufficient for a unitary model. We also show that the presence
of prices or total expenditure in the sharing rule cannot be used as a test for a unitary model.

The relationship between contributions and elicited beliefs in a repeated two-person public good experiment is modeled with the help of a parsimounious random-utility function that allows for conditionally cooperative, opportunistic, and altruistic patterns of behavior. Under standard assumptions, a latent-class mixed logit specification with three sub-populations is shown to capture well heterogeneity in individual contribution levels over time, while also accomodating for different degrees of heteroscedasticity. The estimation results are consistent with the conjecture that the majority of players in public goods games are strongly conditional cooperators, with smaller fractions of the population leaning to opportunistic or altruistic behavior. 相似文献

AbstractIn this article, we proposed a new three parameter lifetime distribution motivated mainly by lifetime issues, which generalizes the Exponential Poisson distribution proposed by Cancho et al. (2011). We derive various standard mathematical properties of the proposed model including a formal proof of its probability density function and hazard rate function. The inference via the maximum likelihood approach is discussed. The performance of the maximum likelihood estimators, the likelihood ratio test and its power are studied by simulation. Finally, the proposed model is fitted to two real data sets and it is compared with several models. 相似文献

Questions related to lotteries are usually of interest to the public since people think there is a magic formula which will help them to win lottery draws. This note shows how to compute the expected waiting time to observe specific numbers in a sequence of lottery draws and show that surprising facts are expected to occur. 相似文献

From the literature three types of predictors for factor scores are available. These are characterized by the constraints: linear, linear conditionally unbiased, and linear correlation preserving. Each of these constraints generates a class of predictors. Best predictors are defined in terms of Lowner's partial matrix order applied to matrices of mean square error of prediction. It is shown that within the first two classes a best predictor exists and that it does not exist in the third. 相似文献
