Georges Friedmann (1902-1977) is known as the founder, following WW II, of a “sociology of humanist work”. Before the war, he was a Marxist intellectual, close to the Communist Party, who admired the young Soviet Union. How this political and ideological itinerary affected his sociology of labor, has never been systematically analyzed. To do so, “machinism” (mechanization), a key concept in the first part of Friedmann’s writing, is scrutinized. This concept came not from Marx, but from Michelet’s romantic conception of history, with which Friedmann was familiar. Following the war, it was given up for the pair “natural/technical milieu”; but this shift in vocabulary did not radically alter Friedmann’s views. Questions arise about how the intellectual itinerary of the founder of French labor sociology, who was shaped by the political trauma experienced by his generation, has lastingly affected this discipline. 相似文献

The Cohen kappa is probably the most widely used measure of agreement. Measuring the degree of agreement or disagreement in
square contingency tables by two raters is mostly of interest. Modeling the agreement provides more information on the pattern
of the agreement rather than summarizing the agreement by kappa coefficient. Additionally, the disagreement models in the
literature they mentioned are proposed for the nominal scales. Disagreement and uniform association models are aggregated
as a new model for the ordinal scale agreement data, thus in this paper, symmetric disagreement plus uniform association model
that aims separating the association from the disagreement is proposed. Proposed model is applied to real uterine cancer data. 相似文献

Stability and change in kindergartners' friendships were examined based on a typology of profiles (stable, fluid, loss, gain, friendless). Our purpose was to determine whether children belonging to the five profiles differed in their social functioning. The sample was composed of 2353 kindergartners. Reciprocal friendships and social functioning indices were measured using peer nominations collected in October and May of the same year. A series of repeated measures analysis of variance indicated that children in the friendless profile were less accepted by their peers, more shy, more withdrawn, and more aggressive than other children. Moreover, children in the stable profile were significantly more accepted by their peers, more prosocial, and less shy than children in the fluid profile. Lastly, children in the loss profile became less accepted by their peers and less prosocial over the course of the year whereas children in the gain profile became more accepted and prosocial. 相似文献

This article is devoted to the study of tail index estimation based on i.i.d. multivariate observations, drawn from a standard heavy-tailed distribution, that is, of which Pareto-like marginals share the same tail index. A multivariate central limit theorem for a random vector, whose components correspond to (possibly dependent) Hill estimators of the common tail index α, is established under mild conditions. We introduce the concept of (standard) heavy-tailed random vector of tail index α and show how this limit result can be used in order to build an estimator of α with small asymptotic mean squared error, through a proper convex linear combination of the coordinates. Beyond asymptotic results, simulation experiments illustrating the relevance of the approach promoted are also presented. 相似文献

We propose bootstrap prediction intervals for an observation h periods into the future and its conditional mean. We assume that these forecasts are made using a set of factors extracted from a large panel of variables. Because we treat these factors as latent, our forecasts depend both on estimated factors and estimated regression coefficients. Under regularity conditions, asymptotic intervals have been shown to be valid under Gaussianity of the innovations. The bootstrap allows us to relax this assumption and to construct valid prediction intervals under more general conditions. Moreover, even under Gaussianity, the bootstrap leads to more accurate intervals in cases where the cross-sectional dimension is relatively small as it reduces the bias of the ordinary least-squares (OLS) estimator. 相似文献

This longitudinal study examined the covariation between parents' use of control and solicitation, youth willingness to self-disclose to parents, and youth antisocial behavior from ages 13 to 14. Structural equation analyses were conducted on a combined sample of Italian (N = 152) and French Canadian (N = 151) adolescents. Analyses tested for longitudinal cross-lagged effects while controlling for stability and all concurrent associations. Although bivariate correlations showed consistent associations among these constructs, both concurrently and over one year, SEM results revealed virtually no cross-lagged effects, after controlling for concurrent associations and stability. These findings suggest that the actual causal effects of parenting and youth behavior may best be conceptualized as occurring in the moment, rather than over extended periods of time. Results also showed that parental control and solicitation demonstrated very different associations with youth antisocial behavior, and should therefore be considered separately for research and prevention. 相似文献

This study examined (a) growth curves of youth participation in sports, performance and fine arts, and youth clubs throughout the high school years and (b) the associations between a series of predictors and the initial participation rates and growth over time. The predictors included individual, friend, and family factors. The moderating effect of youths' gender was also examined. Study participants were 272 youths (55% girls, Mage=12.4 years) and their parents. The predictors were assessed in Grade 6 and were based on reports by youths, parents, teachers, and classmates. Participation in organized activities was assessed annually from Grades 7 to 10. Altogether, the findings revealed that participation in sports, performance and fine arts, and youth clubs remains stable across the high school years. However, interindividual differences were found in the participation growth curves. This variation was predicted by individual, friend, and family factors, mostly with respect to sports activities. 相似文献

Replacing the Canadianization Generation: An Examination of Faculty Composition from 1977 through 2017 下载免费PDF全文
Amid growing numbers of doctoral graduates entering an increasingly competitive global academic job market, concerns about equity in the hiring process and the value of the Canadian Ph.D. are mounting. Grounded within the historical context of the Canadianization Movement, we examine the doctoral credentials of 4,934 U15 social science faculty between 1977 and 2017 to understand the ebb and flow of incoming and outgoing faculty across the country's academic field. Our trend analyses reveal an overall increase in the proportion of Canadian‐trained faculty hires with the noted exceptions of Canada's top three universities who display a strong presence of high‐status American‐trained faculty throughout. Results from the contemporary period, between 1997 and 2017, reveal a time of retirement during which outgoing Canadian‐trained faculty are replaced with increasing proportions of American‐trained academics. 相似文献
