Estimation of population proportion of a qualitative character using randomized response technique in stratified random sampling

This paper proposes an efficient stratified randomized response model based on Chang et al.'s (2004) model. We have obtained the variance of the proposed estimator of π_s, the proportion of the respondents in the population belonging to a sensitive group, under proportional and Neyman allocations. It is shown that the estimator based on the proposed model is more efficient than the Chang et al.'s (2004) estimator under both proportional as well as Neyman allocations, Hong et al.'s (1994) estimator and Kim and Warde's (2004) estimator. Numerical illustration and pictorial representation are given in support of the present study.     

Family Instability,Multipartner Fertility,and Behavior in Middle Childhood

Two concepts capture the dynamic and complex nature of contemporary family structure: family instability and multipartner fertility. Although these circumstances are likely to co‐occur, their respective literatures have proceeded largely independently. The authors used data from the Fragile Families and Child Wellbeing Study (N = 3,062) to consider these dimensions of dynamic family structure together, asking whether they independently predict children's behavior problems at age 9. Frequent family instability was consistently predictive of higher predicted levels of behavior problems for children born to mothers who were unmarried, an association largely attenuated by factors related to family stress. Multipartner fertility was robustly related to self‐reported delinquency and teacher‐reported behavior problems among children born to mothers who were married.     

On randomness, determinism and computability

This paper discusses the meaning and relationship of randomness and determinism. A fundamental development of chaotic dynamical systems is given with examples. Such systems are seen to exhibit randomness in the usual sense of unpredictability. The formal definition of randomness in terms of algorithmic incompressibility is also discussed. The role of recursion in computability and randomness is also discussed.     

新疆人口数量变化能否促进经济增长？--基于VEC模型的动态实证研究

为了研究新疆人口数量变化能否促进经济增长,本文在生态环境承载力、劳动力边际产出和人口理论方面论述了人口数量变化与经济增长的相互作用机理,在此基础上通过VEC模型对人口数量、人均GDP和财政预算收入进行动态研究,结果为：长期人均GDP和人口数量成正向关系,弹性为0.33,但财政预算收入却因人口数量的增加而呈现小幅度降低,弹性为0.09。短期内人均GDP与人口数量成反向关系,财政预算收入的增加反而能够促进人口数量的增加。     

“居间”的辩证法——詹姆斯·费伦的《作为修辞的叙事》的方法论诠释

美国当代著名叙事学家詹姆斯·费伦的近作《作为修辞的叙事》,其方法论将“叙事”视作作者、以文本与读者间意识形态交换的“修辞”为逻辑起点,试图建构一种突显作者、文本和读者交互协同作用的、以文本为中心的动力学话语体系,具有鲜明的“居间”特征。这对国内相关研究有着丰富的启示意义。     

欧洲欲求论探析

欧洲欲求论的思想源远流长.欲求不仅是心理动力学研究的一个主题,而且也是哲学人学和欲望哲学以及伦理学等多学科研究的一个重要课题.笔者探讨了欧洲古代至近代心理欲求论发展的历史轨迹及其主要学说:(1)快乐欲望说;(2)高低欲求说;(3)欲动功能说;(4)运动欲求说;(5)自然欲求说;(6)自爱欲求说.从六种欲求论的学说来看,欲望、欲求、愿望总是同人性观、利益观、价值观、幸福观紧密联系在一起的.人的欲望、欲求是人和社会发展的强大的精神动力.既要反对禁欲主义,又要反对纵欲主义,坚持欲望服从理性,理性统辖欲求,要知足、节制、适度,真正成为自己欲求的主人.     

The social economics of ethical consumption: Theoretical considerations and empirical evidence

Recent years have seen rising discussion of ethical consumption as a means of stemming global warming, challenging unsavory business practices, and promoting other pro-social goals. This paper first lays out a conceptual framework for understanding the spread of ethical consumption, in which heterogeneous preferences and sensitivity to social norms feature centrally. It then presents empirical evidence from a well-known nationally representative survey on factors associated with tendencies to ‘buy ethically’. It is found that, ceteris paribus, people are more likely to buy ethically when others around them do too, consistent with a role of social norms in promoting ethical-consumption behaviors.

流动人口的人际信任、社会支持和幸福感的比较及相互关系研究——以温州为例

比较了流动人口人际信任、社会支持、幸福感在人口学变量上的差异,并探讨了三者间的关系。结果发现:(1)在人际信任变量上,男性显著高于女性;25～30岁流动人口在人际信任上的得分最高,显著高于研究中的其它年龄组;在社会支持变量上,外出打工5年以上的流动人口要显著高于1年及以下(p<0.05)及1～2年(p<0.05);18～25岁流动人口社会支持得分最低,显著低于其它年龄组。在幸福感变量上,男性显著高于女性;签订劳动合同的流动人口显著高于没有签订劳动合同者。(2)在人际信任、社会支持和幸福感关系中,客观支持和主观支持对人际信任与幸福感之间的关系存在一定的调节作用。
