We advocate an interactive approach to examining the role of culture and SES in explaining Asian Americans' achievement. We use Education Longitudinal Study (ELS) 2002 baseline data to test our proposition that the cultural orientation of Asian American families is different from that of white American families in ways that mediate the effects of family SES on children's academic achievement. The results support our hypothesis, indicating that: (1) SES's positive effects on achievement are stronger among white students than among Asian-Americans; (2) the association between a family's SES and behaviors and attitudes is weaker among Asian-Americans than among Whites; (3) a fraction of the Asian-White achievement gap can be accounted for by ethnic differences in behaviors and attitudes, particularly ethnic differences in family SES's effects on behaviors and attitudes. We find that Asian Americans’ behaviors and attitudes are less influenced by family SES than those of Whites are and that this difference helps generate Asians’ premium in achievement. This is especially evident at lower levels of family SES. 相似文献

Age‐specific models of population renewal (with and without feedback) which imply convergence to a stable state for some levels of fertility or feedback may imply the presence of long‐term cycling around a constant or exponentially changing equilibrium for other levels of fertility or feedback. The switch from one regime to the other is a “bifurcation.”; The conditions for bifurcation involve the roots of an analogue of Lotka's Equation. Typically bifurcation is induced by raising the strength of feedback or the level of fertility. It has been known since the early 1980s, however, that this is sometimes impossible. It is sometimes impossible even with the linear renewal equation itself and with the most basic of non‐linear models, Lee's cohort feedback model. Here it is proved that this typical route to bifurcation does not fail for these basic models in the presence of a condition which always holds for realistic applications with higher organisms: the existence of a span of ages before the onset of fertility. Specifically, a strictly positive lower bound on ages of procreation is proved to be sufficient to guarantee the existence of a rescaling of Lotka's Equation for which the real part of some complex root vanishes. This result holds for absolutely Lebesgue‐integrable (signed) net maternity functions on the positive real line and for absolutely summable (signed) net maternities on the positive integers. It follows that Coale's rescaling device for the analysis of approach to stability in stable population theory can be implemented for all realistic human net maternity schedules. It also follows that the many special cases of the cohort feedback model throughout population biology will all generate persistent cycling instead of stability if feedback is sufficiently strong. 相似文献

Rurality is a complex and contested term, with multiple notions and gazes amid calls for theoretical pluralism. In Australia, the spatial categories of ‘remote’, ‘rural’, ‘regional’ and ‘urban’ are applied to places that vary in their distance from an economic and political core and have differing population densities. We argue that natural resources institutions in rural Australia demand an ‘authentic’ performance of Aboriginality that is framed within orthodox and stable constructions of an Indigeneity associated with the remote category. Dominant representations of remote Aboriginal people living on traditional homelands and engaged in ‘traditional’ environmental protection are assumed to hold for all places and transposed when natural resources institutions satisfy compulsory Indigenous engagement. Such institutional requirements for authenticity exclude alternative and multiple Indigenous voices in natural resources management. Rather, Aboriginal people seek engagement across a portfolio of natural resources activities typically found in rural areas (such as mining, grazing, forestry, water allocation planning, and natural resources service delivery and enterprise development), and not just isolated in natural and cultural heritage conservation. This broad participation would more completely match their expressed aspirations and the multiple lived realities of their fluid and networked rural worlds. Using the rural town of Eidsvold in Australia as a case study, we discuss the findings of participant observation and semi-structured interviews with Indigenous people at regional natural resources management meetings and at ‘home’ in Eidsvold. Rather than a generic institutional approach, a place-based approach to understanding the complex ruralities of Aboriginal people is needed. 相似文献

民族交往伴随着民族共同体变迁与发展的整个进程,是构成民族关系的重要内容,民族关系也是通过民族交往具体实现与体现的.本文从阐释交往、民族交往出发,论述了作为人类普遍心理与行为的民族交往及其对社会结构变迁的意义,认为民族的交往内驱力、民族交往认知、民族交往情感、民族交往意识,以及民族交往行为是构成民族交往心理的基本要素. 相似文献

社会学族群关系研究的几种理论视角 总被引:1,自引:0,他引:1
本文主要介绍社会学族群关系研究的主要理论范式,包括源于美国社会的种族主义族群关系理论、社会学族群关系同化范式、权力—冲突范式,并回顾了人类学领域族群性研究的相关启示。传统的客观特征论与晚近对主观认同的强调构成了族群关系与族群性研究的两种主要的分析框架。晚近的研究,强调在民族国家背景下,考虑资源竞争和权力关系对族群关系的影响。 相似文献

This article considers testing serial correlation in partially linear additive errors-in-variables model. Based on the empirical likelihood based approach, a test statistic was proposed, and it was shown to follow asymptotically a chi-square distribution under the null hypothesis of no serial correlation. Finally, some simulation studies are conducted to illustrate the performance of the proposed method. 相似文献

In this paper we propose a new lifetime model for multivariate survival data in presence of surviving fractions and examine some of its properties. Its genesis is based on situations in which there are m types of unobservable competing causes, where each cause is related to a time of occurrence of an event of interest. Our model is a multivariate extension of the univariate survival cure rate model proposed by Rodrigues et al. [37]. The inferential approach exploits the maximum likelihood tools. We perform a simulation study in order to verify the asymptotic properties of the maximum likelihood estimators. The simulation study also focus on size and power of the likelihood ratio test. The methodology is illustrated on a real data set on customer churn data. 相似文献
