Cet article examine l’évolution des niveaux de confiance sociale envers les organisations syndicales au Canada et aux États‐Unis entre 1982 et 2006 en s'appuyant sur les données de la World Value Survey (WVS). Partant du constat que ces taux de confiance sont relativement similaires au sein de ces deux pays, nous appliquons un modèle de régression logistique sur les deux vagues de données les plus récentes du WVS (soit celle de 2000 et 2006) afin de mieux comprendre la propension des individus à faire confiance aux syndicats dans chaque contexte national en fonction de certaines de leurs caractéristiques sociales et politiques. Les résultats montrent des similitudes entre les deux pays (par exemple, les citoyens les plus progressistes et les plus jeunes ont généralement une plus grande confiance envers les syndicats), mais également des distinctions importantes (à titre d'exemple, seul au Canada les individus répondant à un profil de “classe ouvrière” manifestent une plus grande confiance envers les syndicats). This article examines changes in levels of social confidence in unions in Canada and the United States between 1982 and 2006 based on an analysis of the World Value Survey (WVS) data set. It considers why confidence rates are similar in the two countries, applying a logistic regression model to the two most recent WVS waves (i.e., 2000 and 2006) so as to bring out the effects of political and social differences on the propensity of individuals to trust unions in each national context. The results show similarities between the two countries (e.g., more progressive and younger citizens generally have greater confidence in unions), but also important distinctions (e.g., only in Canada do individuals with a working class profile appear to have greater confidence in unions).  相似文献

We used observed parenting behaviors, along with genetic variants and haplotypes of the serotonin transporter gene (SLC6A4), as predictors of children's ego‐resiliency during early childhood (N = 153). The quality of mothers' parenting was observed at 18 months of age, and mothers' reports of ego‐resiliency were collected at six time points from 18 to 84 months. Genetic data were collected at 72 months. Observed parenting was positively associated with initial levels of children's ego‐resiliency. Furthermore, although individual genetic variants of the serotonin transporter gene (LPR, STin2) were not associated with ego‐resiliency, the S10 haplotype (that combines information from these two variants) was negatively associated with initial levels of ego‐resiliency. Both parenting and serotonin genetic variation uniquely predicted children's ego‐resiliency, suggesting an additive effect of genetic and parental factors.  相似文献

Consider longitudinal networks whose edges turn on and off according to a discrete-time Markov chain with exponential-family transition probabilities. We characterize when their joint distributions are also exponential families with the same parameter, improving data reduction. Further we show that the permutation-uniform subclass of these chains permit interpretation as an independent, identically distributed sequence on the same state space. We then apply these ideas to temporal exponential random graph models, for which permutation uniformity is well suited, and discuss mean-parameter convergence, dyadic independence, and exchangeability. Our framework facilitates our introducing a new network model; simplifies analysis of some network and autoregressive models from the literature, including by permitting closed-form expressions for maximum likelihood estimates for some models; and facilitates applying standard tools to longitudinal-network Markov chains from either asymptotics or single-observation exponential random graph models.  相似文献

Twenty years ago, the National Institute of Child Health and Human Development (NICHD) issued a request for proposals that resulted in the National Survey of Families and Households (NSFH), a unique survey valuable to a wide range of family scholars. This paper describes the efforts of an interdisciplinary group of family demographers to build on the progress enabled by the NSFH and many other theoretical and methodological innovations. Our work, also supported by NICHD, will develop plans for research and data collection to address the central question of what causes family change and variation. We outline the group's initial assessments of orienting frameworks, key aspects of family life to study, and theoretical and methodological challenges for research on family change. Finally, we invite family scholars to follow our progress and to help develop this shared public good.  相似文献

Most versions of identity theory have had difficulty explaining the persistence of invalidated identities. Drawing from data on anorexic identity transactions, we identify three dimensions that contribute to understanding this persistence. Two dimensions, size and control, are shown to be the locus of identity invalidation; the third, desirability, is shown to be the locus of validation. Confirmation of one's sense of being desirable, we propose, contributes to anorexics continuing to appropriate identities invalidated by others. We argue that the concepts “master identity,” “fictionalized identity,” and what we term “discordant awareness context” are more useful for theorizing the persistence of invalidated identities, such as anorexia, than those focusing on the degree of consensus over the person as a social object found in conventional identity theory.  相似文献

The experiment reported here investigated infants' concept of intention, as well as the relation among intention understanding, general productive vocabulary, and internal state language production during the 2nd year. Results from an imitation task indicated that 18‐month‐olds are better able to differentiate between intentional and accidental actions than 14‐month‐olds. Although there was no relation between infants' performance on the intention task and their general productive vocabulary, internal state language production at 30 months was predicted by infants' ability to differentiate between intentional and accidental actions about a year earlier. These findings shed light on the developmental progression of infants' concept of intention, as well as on the continuity between infants' understanding of intentional action and their ability to use internal state words.  相似文献

When spatial data are correlated, currently available data‐driven smoothing parameter selection methods for nonparametric regression will often fail to provide useful results. The authors propose a method that adjusts the generalized cross‐validation criterion for the effect of spatial correlation in the case of bivariate local polynomial regression. Their approach uses a pilot fit to the data and the estimation of a parametric covariance model. The method is easy to implement and leads to improved smoothing parameter selection, even when the covariance model is misspecified. The methodology is illustrated using water chemistry data collected in a survey of lakes in the Northeastern United States.  相似文献

The authors examine the asymptotic behaviour of conditional threshold exceedance probabilities for an elliptically distributed pair (X, Y) of random variables. More precisely, they investigate the limiting behaviour of the conditional distribution of Y given that X becomes extreme. They show that this behaviour differs between regularly and rapidly varying tails.  相似文献
