Differences in sexual desire between individuals of East Asian and European descent are well-documented, with East Asian individuals reporting lower sexual desire. The mechanisms that underlie this disparity have received little empirical attention. Recent research has found that sex guilt, "a generalized expectancy for self-mediated punishment for violating or for anticipating violating standards of proper sexual conduct" (Mosher & Cross, 1971 , p. 27), mediates the relationship between culture and sexual desire in East Asian and Euro-Canadian women. The goal of this study was to explore this role of sex guilt in men. Male Euro-Canadian (n?=?38) and East Asian (n?=?45) university students completed online questionnaires. The East Asian men reported significantly lower sexual desire and significantly higher sex guilt. Sex guilt was a significant mediator of the relationship between ethnicity and sexual desire, as well as a significant mediator between mainstream acculturation and sexual desire. Among the East Asian men, mainstream acculturation was significantly and negatively correlated with sex guilt such that increasing mainstream acculturation was associated with less sex guilt. The diagnostic and clinical implications of the findings are discussed. 相似文献

The cross-national investigation of immigrant subjective well-being remains an understudied field, especially with regard to the link between institutional settings and individual outcomes. We approach this gap by investigating the role of policies regulating immigrant integration for life satisfaction. Immigrants’ status and life chances depend on the inclusiveness of integration policies in forms of rights given to immigrants in the receiving country. These policies differentiate immigrants from natives: exclusionary integration policies understood as social boundaries should result in lower levels of well-being. We also consider an alternative policy type (i.e. multicultural policies) as well as symbolic boundaries (i.e. natives’ attitudes towards immigrants). We distinguish between national citizens, EU citizens and third-country nationals (TCNs). Results based on up to five rounds of data from the European Social Survey indicate that in terms of life satisfaction only TCNs profit from inclusive integration policies. Furthermore, while political multiculturalism does not play a role, we find that EU migrants appear more susceptible to the negative impact of natives’ anti-immigrant attitudes. Policy-making is more important for TCNs, while a migrant-friendly opinion climate is more important for EU migrants. These findings are robust to controlling for unobserved time-constant country heterogeneity via country fixed effects. 相似文献

Convergence faible sur des espaces topologiques uniformes et suites aléatoires d'éléments aléatoires
Boris Kohler 《Revue canadienne de statistique》1977,5(2):219-225
Following some results on weak convergence, theorems are given on the selection of sample elements on uniform spaces. Our results are tied in with a theorem of Fernandez (1971, p. 1740). 相似文献

We suggest a new approach to hypothesis testing for ergodic and stationary processes. In contrast to standard methods, the suggested approach gives a possibility to make tests, based on any lossless data compression method even if the distribution law of the codeword lengths is not known. We apply this approach to the following four problems: goodness-of-fit testing (or identity testing), testing for independence, testing of serial independence and homogeneity testing and suggest nonparametric statistical tests for these problems. It is important to note that practically used so-called archivers can be used for suggested testing. 相似文献

In modelling financial return time series and time-varying volatility, the Gaussian and the Student-t distributions are widely used in stochastic volatility (SV) models. However, other distributions such as the Laplace distribution and generalized error distribution (GED) are also common in SV modelling. Therefore, this paper proposes the use of the generalized t (GT) distribution whose special cases are the Gaussian distribution, Student-t distribution, Laplace distribution and GED. Since the GT distribution is a member of the scale mixture of uniform (SMU) family of distribution, we handle the GT distribution via its SMU representation. We show this SMU form can substantially simplify the Gibbs sampler for Bayesian simulation-based computation and can provide a mean of identifying outliers. In an empirical study, we adopt a GT–SV model to fit the daily return of the exchange rate of Australian dollar to three other currencies and use the exchange rate to US dollar as a covariate. Model implementation relies on Bayesian Markov chain Monte Carlo algorithms using the WinBUGS package. 相似文献

A family of threshold nonlinear generalised autoregressive conditionally heteroscedastic models is considered, that allows smooth transitions between regimes, capturing size asymmetry via an exponential smooth transition function. A Bayesian approach is taken and an efficient adaptive sampling scheme is employed for inference, including a novel extension to a recently proposed prior for the smoothing parameter that solves a likelihood identification problem. A simulation study illustrates that the sampling scheme performs well, with the chosen prior kept close to uninformative, while successfully ensuring identification of model parameters and accurate inference for the smoothing parameter. An empirical study confirms the potential suitability of the model, highlighting the presence of both mean and volatility (size) asymmetry; while the model is favoured over modern, popular model competitors, including those with sign asymmetry, via the deviance information criterion. 相似文献
