南京临时政府时期的近代国家转型与民族关系之建构——以“五族共和”为中心

南京临时政府时期是中国近代国家转型与民族关系之建构的重要阶段,其基本情态就是"五族共和"。它是一个历史建构过程,包括思想文化领域与政治实践领域的双重认同与整合,同时也表明了中国近代国家转型与民族关系建构过程中的重要历史转折。由于阶级和时代的局限,"五族共和"在理论认识和具体实践中仍然存在严重的现实困境和诸多问题,中国近代国家转型与民族关系之建构仍然面临严重的危机和挑战。     

城市“外来蓝领”的就业与社会融合

利用中国人民大学人口与发展研究中心2005年7月在广东省惠州市的调查数据,以数家企业中的"外来蓝领"(即工厂、企业中的外来务工人员)为样本,对这些在企业中工作的外来务工人员的就业状况和社会融合进行分析。结果表明,这些"外来蓝领"对务工地的选择并非是盲目的,他们外出的动机开始呈现多元化趋势;随着国家一系列关于农民工培训和保障政策的出台,接受调查的大多数"外来蓝领"与用人单位之间签订了劳动合同,并对合同的内容有一定的了解,然而他们对政府的法规依赖性高,并且由于户口的限制,他们的社会保险在实施层面还存在较大的不足;尽管"外来蓝领"在与社区融合方面表现出较强的能力,但是同城市当地人之间的交流缺乏,造成其社会融合程度低,形成了"蚁巢"现象。

The influence of acculturation level and family relationships on quality of life among U.S. Chinese older adults

ABSTRACT

The present study examined the influence of acculturation level and family relationships (i.e., positive family support and negative family strain) on quality of life (QOL), using the data from the Population Study of ChINese Elderly (PINE) in Chicago (N = 3159). Controlling for sociodemographic variables and health status, it was found that individuals’ acculturation level and positive family support were positively related to QOL, whereas negative family strain was negatively associated with QOL. More importantly, higher acculturation levels were associated with increased protective effects of positive family support and reduced risk effects of negative family strain on QOL among U.S. Chinese older adults.     

On extreme order statistics from heterogeneous beta distributions with applications

This paper treats the problem of stochastic comparisons for the extreme order statistics arising from heterogeneous beta distributions. Some sufficient conditions involved in majorization-type partial orders are provided for comparing the extreme order statistics in the sense of various magnitude orderings including the likelihood ratio order, the reversed hazard rate order, the usual stochastic order, and the usual multivariate stochastic order. The results established here strengthen and extend those including Kochar and Xu (2007 Kochar, S.C., Xu, M. (2007).

A real application in system assembly and some numerical examples are also presented to illustrate the theoretical results.     

Improved estimation methods for unrelated question randomized response techniques

The randomized response technique (RRT) is an important tool, commonly used to avoid biased answers in survey on sensitive issues by preserving the respondents’ privacy. In this paper, we introduce a data collection method for survey on sensitive issues combining both the unrelated-question RRT and the direct question design. The direct questioning method is utilized to obtain responses to a non sensitive question that is related to the innocuous question from the unrelated-question RRT. These responses serve as additional information that can be used to improve the estimation of the prevalence of the sensitive behavior. Furthermore, we propose two new methods for the estimation of the proportion of respondents possessing the sensitive attribute under a missing data setup. More specifically, we develop the weighted estimator and the weighted conditional likelihood estimator. The performances of our estimators are studied numerically and compared with that of an existing one. Both proposed estimators are more efficient than the Greenberg's estimator. We illustrate our methods using real data from a survey study on illegal use of cable TV service in Taiwan.     

基于DPN模型的我国出口拉动增加值时滞模型

由于我国加工出口占比较高,学者们提出了区分贸易方式的非竞争型投入产出模型.该模型可以更加准确地测算我国出口对增加值的拉动,但是该模型忽略了出口对增加值拉动的时滞性,这容易产生所有效应都在当年发生的误解.文章基于区分贸易方式的非竞争型投入产出模型构建了各部门出口对增加值拉动的时滞模型.实证结果表明:非加工出口部门的时滞长于加工出口部门的时滞.     

“农转非”、人力资本回报与收入不平等——基于分位数回归分解的方法

随着中国城镇化进程的推进,越来越多的农村户籍人口实现了身份转换,成为制度认可的新市民。本文利用中国综合社会调查（CGSS）数据发现,即使户口状况相同,"新市民"与"老市民"之间依然存在一定的收入差距。分位数回归及其分解的结果显示,"农转非"人群在劳动力市场上仍受到制度性或非制度性歧视,且歧视程度随着分位数的变化呈现倒U型趋势。同时,"农转非"人群内部也存在较大的差异,歧视降低了自致型"农转非"人群相较于城市原居民的禀赋优势,而外致型"农转非"人群则面临人力资本劣势与就业市场歧视的双重压力。     

Affective networks: how WeChat enhances Tencent’s digital business governance

An emerging body of literature has revealed that social media enhance digital business governance to facilitate Internet companies in generating profit throughout regulating the everyday lives of users. However, although existing debates are often contextualized in the West, little attention has been paid to China, where social media are widely used. To fill this knowledge gap, this article investigates the digital business governance practiced by Chinese Internet companies such as Tencent. Specifically, I employ an affective lens to analyze how WeChat, the most popular social media application launched by Tencent, allows this Internet company to influence users for its own business purposes. Chinese college students, which constitute a representative group of young people, were early adopters of WeChat, and they have led the trend of social media use in China. Based on a yearlong netnographic study of Chinese college students, the results reveal that the affective design of WeChat captured their attention and influenced their everyday practices. These results provide insight into how digital business governance operates in the Chinese context, in which authoritarianism and capitalism work closely together.
