Racial diversity, minority concentration, and trust in Canadian urban neighborhoods

Using a sample of 42,329 respondents nested within 4254 Canadian urban neighborhoods, this study demonstrates the conceptual and empirical importance of making a distinction between neighborhood racial diversity and minority concentration, and examines how each is uniquely associated with trust. Our analysis shows that at a given level of racial minority concentration, Whites are more trusting when their minority neighbors are more evenly distributed across racial minority groups. Meanwhile, Whites are less trusting as the neighborhood share of racial minorities increases. Overall, the effect of racial minority concentration tends to prevail over that of racial diversity.

从概念厘定到理论运用:西方民族冲突研究述评

此起彼伏、经久不息的民族冲突引发了国内外学术界的高度关注。自20世纪后半期,尤其是90年代以来,西方关于民族冲突的研究取得了快速发展。内容涉及界定概念、扩展范畴、探究原因、寻找规律和思考对策,尤其是在理论运用方面,致力于实现民族机制、冲突机制和国际关系机制的内在统一,为更好地理解民族冲突,探求解决民族冲突的理路提供了启示。

The optimism trap: Migrants’ educational choices in stratified education systems

Immigrant children's ambitious educational choices have often been linked to their families' high level of optimism and motivation for upward mobility. However, previous research has mostly neglected alternative explanations such as information asymmetries or anticipated discrimination. Moreover, immigrant children's higher dropout rates at the higher secondary and university level suggest that low performing migrant students could have benefitted more from pursuing less ambitious tracks, especially in countries that offer viable vocational alternatives. We examine ethnic minority's educational choices using a sample of academically low performing, lower secondary school students in Germany's highly stratified education system. We find that their families' optimism diverts migrant students from viable vocational alternatives. Information asymmetries and anticipated discrimination do not explain their high educational ambitions. While our findings further support the immigrant optimism hypothesis, we discuss how its effect may have different implications depending on the education system.     

Estimation and diagnostic for skew-normal partially linear models

Partially linear models (PLMs) are an important tool in modelling economic and biometric data and are considered as a flexible generalization of the linear model by including a nonparametric component of some covariate into the linear predictor. Usually, the error component is assumed to follow a normal distribution. However, the theory and application (through simulation or experimentation) often generate a great amount of data sets that are skewed. The objective of this paper is to extend the PLMs allowing the errors to follow a skew-normal distribution [A. Azzalini, A class of distributions which includes the normal ones, Scand. J. Statist. 12 (1985), pp. 171–178], increasing the flexibility of the model. In particular, we develop the expectation-maximization (EM) algorithm for linear regression models and diagnostic analysis via local influence as well as generalized leverage, following [H. Zhu and S. Lee, Local influence for incomplete-data models, J. R. Stat. Soc. Ser. B 63 (2001), pp. 111–126]. A simulation study is also conducted to evaluate the efficiency of the EM algorithm. Finally, a suitable transformation is applied in a data set on ragweed pollen concentration in order to fit PLMs under asymmetric distributions. An illustrative comparison is performed between normal and skew-normal errors.     

浅析中国近现代回族报刊的经济功能

由于近现代回族报刊中并没有专门的经济类报刊,因而普通报刊的经济功能被开发出来,对广大回族企业和相关经济活动起到了较好的引导和规范作用。诸如《边铎》《天山》《晨熹》等一系列回族报刊的出现,其中所描述的经济行为,所解析的经济政策等相关内容不仅提供了重要的回族经济史依据,而且还在客观上也大大缓解了当时回族聚居区的经济压力,刺激了当时回族产业的新模式的生成,并促进了当地经济和社区的繁荣,从而协调了部分政治性矛盾,进而推动了一些文化问题的解决。     

综析经济法的精髓

经济集中,是指经济权威组织管理参与经济活动的权力以及为实现上述经济权力而制定的制度和程序.经济民主,是指经济活动主体行使权利的自由以及为实现这些权利所设定的制度和程序.经济法的精髓是经济集中与经济民主的对立统一.这种对立统一关系,在经济领域表现为国家干预和市场调节的对立统一;在政治领域的动因和表现为国家机器职能的转变;在法学领域的动因和表现是"社会本位"法理念的兴起和传统法学理论的突破;在法律领域的表现是经济法这一法律部门的出现.     

湄公河名称的含义及其所反映的民族历史变迁

湄公河这个名称是从英文MekongRiver一名音译过来的,而英文Mekong这个名称又是从傣泰语民族对这条河流的称呼MaeNamKhong这个名称演变过来的。如果按照傣泰语的发音来音译的话,MaeNamKhong应该译为“湄南公”。在傣泰语言中,“湄南”是河的意思,而“公(”Khong)这个词,则是从Krom或Khom这个词演变而来的。Krom或Khom是泰国的泰族和其他一些傣泰语民族对孟高棉语民族的一个泛称。因此,“湄南公”是湄公河的名称的含义,就是“孟高棉语民族的河”。作者认为,傣泰语民族把流经他们土地的这条河流叫做“孟高棉语民族的河”的原因在于:这个名称反映了一段湄公河流域民族变迁的历史,即孟高棉语民族是该流域的土著居民,至少是比傣泰民族要早的当地居民,而傣泰民族则是后来才迁到该河流域的民族。虽然孟高棉语民族和傣泰语民族在该流域的分布空间已发生了根本的置换,但湄公河这条河流的名称却为我们留下了一条反映这种民族历史变迁的重要线索。
