大学生弱势群体自我认知研究   总被引:3,自引:0,他引:3  
本文从心理学视角,采用调查法,探讨大学生弱势群体自我认知为弱势的原因及弱势类型,结果表明经济因素、学习因素和学校关系因素是引起大学生自我认知为弱势的重要原因;经过聚类分析发现,大学生弱势群体可分为家庭——经济弱势、人际——心理弱势、学校认可弱势和经济——学习弱势四种类型。  相似文献

Generalised estimating equations (GEE) for regression problems with vector‐valued responses are examined. When the response vectors are of mixed type (e.g. continuous–binary response pairs), the GEE approach is a semiparametric alternative to full‐likelihood copula methods, and is closely related to Prentice & Zhao's mean‐covariance estimation equations approach. When the response vectors are of the same type (e.g. measurements on left and right eyes), the GEE approach can be viewed as a ‘plug‐in’ to existing methods, such as the vglm function from the state‐of‐the‐art VGAM package in R. In either scenario, the GEE approach offers asymptotically correct inferences on model parameters regardless of whether the working variance–covariance model is correctly or incorrectly specified. The finite‐sample performance of the method is assessed using simulation studies based on a burn injury dataset and a sorbinil eye trial dataset. The method is applied to data analysis examples using the same two datasets, as well as to a trivariate binary dataset on three plant species in the Hunua ranges of Auckland.  相似文献

We propose a new method for smooth isotonic regression analysis. Unlike most existing methods for isotonic regression, the proposed method is akin to parametric regression without order restriction. To account for smoothness and isotonicity simultaneously, we exploit the flexible class of semi-non parametric densities to model isotonic regression functions. Under this framework, the full range of inference techniques for parametric regression models become applicable for model estimation and model validation in isotonic regression.  相似文献

Voting procedure is an important mechanism for public choice in collective bodies such as international organizations. This paper measures and compares IMF member countries’ voting power before the 2008 reform and after the 2010 reform on the basis of datasets on IMF quotas and voting rights distribution provided by IMF. Our study verifies that IMF’s quotas and voting rights reforms do help to reduce the voting power gap among member countries. The 2008 and 2010 reforms produce a greater improvement in emerging members’ voting power under the 70 percent majority rule than the 85 percent rule; the 70 percent majority rule means the United States would lose its absolute veto. Moreover, the paper disproves the underlying assumption that regards a member’s voting power as proportional to its voting rights. Countries with different amounts of voting rights can still have the same voting power.  相似文献

In this article we consider the Double Eleven shopping festival as a major discursive site where the hegemony of what we call patriarchal capitalism with Chinese characteristics is articulated. The state, the market, the corporations and the media, both mainstream and social media, all played an important role in building up a national spending spree that is deeply embedded in the current class and gender structure of China. The phenomenon of Double Eleven emerged at a time when state capitalism has been overwriting socialist institutions, while patriarchal ideology being further intensified through consumerism. As a consequence, the intersectionality of class and gender becomes increasingly manifest in the Chinese society. We start with a brief overview of the trajectory of gender politics in China since 1949, with specific focus on how the socialist project of seeking gender equality was gradually replaced by the quest for ‘womanhood’ and ‘femininity’. We then discuss, using both secondary sources and our own analysis of news coverage of Double Eleven, why maintaining a high level of consumer demand is of crucial importance for the Chinese state and what the state’s role has been in configuring the hegemonic gender order. A brief section on ideology and discourse lays out the conceptual framework of our analysis. It is at the intersection of a dissipating socialist ethos, emerging economic stagnation and ascending consumerism that the sexist discourse in relation to Double Eleven proliferates, and this is the analytical focus of our empirical section. We elaborate on the theoretical implications of the empirical analysis before concluding.  相似文献

This paper addresses the collinearity problems in semi-parametric linear models. Under the difference-based settings, we introduce a new diagnostic, the difference-based variance inflation factor (DVIF), for detecting the presence of multicollinearity in semi-parametric models. The DVIF is then used to device a difference-based matrix perturbation method for solving the problem. The electricities distribution data set is analyzed, and numerical evidences validate the effectiveness of the proposed method.  相似文献

Objectives: Metabolic syndrome (MtS) and kidney stone are two common aging diseases with male dominant. This is the first study regarding the potential impact of MtS and its components on kidney stone in aging Chinese population.

Methods: A total of 694 males with a mean age of 55.6 years were enrolled. The definition of MtS was according to the modified criteria developed by the Bureau of Health Promotion in Taiwan. Subjects were classified as having a disease of kidney stones according to diagnosis by a physician with available medical records or evidence from ultrasonography judged by an investigator of urologist.

Results: Using age-adjusted multivariate logistic regression analysis, our results showed that subjects with kidney stone had significantly higher prevalence of MtS (p?=?0.04, OR?=?1.74, 95% CI: 1.0 1–3.00). The presence of MtS had significant correlation with kidney stone (p?=?0.01, OR?=?1.83, 95% CI: 1.1 4–2.93), which were associated with the increment of MtS components (p?p?Conclusions: In aging Taiwanese males, the presence of MtS and its components are strongly associated with kidney stone. Abnormal BP is the most significant risk component of MtS for kidney stone.  相似文献

This paper examines contemporary developments among Taiwan’s indigenous Austronesian peoples. We have reviewed major policy changes mainly since the 1980s and their impacts on later developments – both the positive improvements in general well-being and the persistence of ingrained problems among them. Major findings indicate two growing trends among Taiwanese Austronesians. One is the rise of interest in their cultures and efforts to preserve and restore selected indigenous customs and practices. The other trend is a continuous outflow of the indigenes from traditional tribal communities to urban centers for better employment, education, or health care. Their increasing urbanization also contributes to more inter-ethnic marriages and the loss of indigenous languages and practices. The case of Taiwanese Austronesians illustrates the impacts historical and politico-economic processes are having on indigenous peoples.  相似文献
