This article is about ‘coming out’ and the process of disclosure of queer migrants within their transnational families. Despite debates about the decreasing relevance of coming out in contemporary western societies, we argue that the process of coming out continues to be a central mode of belonging and identity construction for queers in the context of transnational migration. Interviews with migrants from Poland, Russia and Turkey in Germany on their coming out experiences show that people rely on a variety of boundaries, i.e. gender, class and ethnicity, to construct a desired way of life. Theoretically, these insights indicate the need to reframe post-structuralist theories on power, most prominently advanced by Pierre Bourdieu and Michel Foucault, from an intersectional perspective. The findings in this paper pinpoint to the challenges of transnational social life queer migrants are confronted with through empirical illustrations of perceptions of differences and ambiguities between immigration and emigration contexts. Furthermore, we advocate that sexuality is a crucial dimension of migration processes determining self-definition in relation to people and places, which makes their stories of coming out always also stories of ‘coming home’.  相似文献

This paper shows that the problem of testing hypotheses in moment condition models without any assumptions about identification may be considered as a problem of testing with an infinite‐dimensional nuisance parameter. We introduce a sufficient statistic for this nuisance parameter in a Gaussian problem and propose conditional tests. These conditional tests have uniformly correct asymptotic size for a large class of models and test statistics. We apply our approach to construct tests based on quasi‐likelihood ratio statistics, which we show are efficient in strongly identified models and perform well relative to existing alternatives in two examples.  相似文献

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized techniques. We consider both linear and nonlinear models where the regression coefficients are heterogeneous across groups but homogeneous within a group and the group membership is unknown. Two approaches are considered—penalized profile likelihood (PPL) estimation for the general nonlinear models without endogenous regressors, and penalized GMM (PGMM) estimation for linear models with endogeneity. In both cases, we develop a new variant of Lasso called classifier‐Lasso (C‐Lasso) that serves to shrink individual coefficients to the unknown group‐specific coefficients. C‐Lasso achieves simultaneous classification and consistent estimation in a single step and the classification exhibits the desirable property of uniform consistency. For PPL estimation, C‐Lasso also achieves the oracle property so that group‐specific parameter estimators are asymptotically equivalent to infeasible estimators that use individual group identity information. For PGMM estimation, the oracle property of C‐Lasso is preserved in some special cases. Simulations demonstrate good finite‐sample performance of the approach in both classification and estimation. Empirical applications to both linear and nonlinear models are presented.  相似文献

In this paper, we propose a robust estimation procedure for a class of non‐linear regression models when the covariates are contaminated with Laplace measurement error, aiming at constructing an estimation procedure for the regression parameters which are less affected by the possible outliers, and heavy‐tailed underlying distribution, as well as reducing the bias introduced by the measurement error. Starting with the modal regression procedure developed for the measurement error‐free case, a non‐trivial modification is made so that the modified version can effectively correct the potential bias caused by measurement error. Large sample properties of the proposed estimate, such as the convergence rate and the asymptotic normality, are thoroughly investigated. A simulation study and real data application are conducted to illustrate the satisfying finite sample performance of the proposed estimation procedure.  相似文献

资产专用性对确权后农地流转的影响   总被引:1,自引:0,他引:1  
农地确权后,农户对农地转出多持中立或否定的态度,这与产权明晰促进交易的产权理论大相径庭。文章探讨了资产专用性对确权后农地流转的作用机理,并运用吉林省9市1444个农户数据对其进行实证分析。结果表明:农地确权后,土地资产、农业资产、地理位置以及人力资本等专用性抑制农户转出农地,农业资产和人力资本专用性抑制农户提高农地租金,而社会资本专用性则分别存在促进作用;农业资产、地理位置以及人力资本等专用性抑制农户更长时间转出农地;农业资产专用性对转出农地须要签订合约具有抑制作用,而地理位置专用性则存在促进作用。  相似文献

We propose an influence diagnostic methodology for linear regression models with stochastic restrictions and errors following elliptically contoured distributions. We study how a perturbation may impact on the mixed estimation procedure of parameters in the model. Normal curvatures and slopes for assessing influence under usual schemes are derived, including perturbations of case-weight, response variable, and explanatory variable. Simulations are conducted to evaluate the performance of the proposed methodology. An example with real-world economy data is presented as an illustration.  相似文献

The Olmstead Decision of 1999 continues to have the potential to radically transform the long-term care system in the United States. This article will review the components of the decision and steps being taken by the federal and state governments to address its challenges and mandates. A number of key areas where social workers can play important roles will be described.  相似文献

立德树人居于学校教育发展全局的核心位置,需要将其落实到课程育人的生动实践中。但是,在课程育人的具体实践中,仍有部分教师将其简单化为“课程+育人”的生硬结合,导致课程育人容易陷入理论教条窠臼。为此,高校教师应充分认识到高校课程育人在目标要求、重点内容、转型路径上的人性化、时代化和数字化本真意蕴,从教师素养、课程建设、课堂教学三个方面开展育人实践。在此基础上,针对具体课程的育人效果而言,可以从目标设定、内容选择、方法实施、结果呈现等方面进行评价,从而进一步推动课程育人的生动实践。  相似文献
