我国区域不均等:分解方法与实证分析

在对区域不均等度量指标及分解方法进行归纳性阐释的基础上,运用泰尔指数分析了我国自20世纪80年代中后期以来的区域不均等,并对我国区域差异中的城乡收入差距,东中西部农村地区的收入差距进行了分解。结果表明,在总的不均等中约70-80%的不均等来自城乡之间,只有20%-30%是由城市和农村内部引起的。东中西之间的不均等对总不均等的贡献大约只有20-30%,剩下的70-80%则归因于东中西各自内部不同省份之间的差距。     

Continuous outcomes stochastically mismeasured as discrete random variables: a maximum likelihood approach

In an economic model of retirement behavior, a continuous dependent variable was required; the variable could only be estimated discretely with error, however. Parameter estimates using this dependent variable and ordinary least squares regression are inefficient. In th is paper, we develop a maximum likelihood procedure which adjusts for this heteroscedasticity.

Social status and personality traits

We provide direct evidence on the relationship between social status and personality traits. Using survey data from the 2006–2012 waves of the US Health and Retirement Study, we show that self-perceived social status is associated with all the “Big Five” personality traits, after controlling for observable characteristics that arguably reflect one’s actual status. We also construct an objective status measure that in turn is associated with personality traits. Objectively measured status is positively but not highly correlated with its subjective counterpart. When incorporated in a regression specification, it still leaves room for significant correlations between personality traits and status perception: traits such as openness, conscientiousness and extraversion predict a higher self-positioning on the social ladder, while agreeableness and neuroticism predict a lower one.     

基于城市经济空间联系的江西省区域发展研究

针对宽高比为5的矩形断面梁进行了节段模型测压风洞试验,研究了矩形断面梁的气动力特性随风攻角的变化规律。研究结果表明：在0°~6°的风攻角范围内,风攻角对斯托罗哈数的影响很小;不同风攻角下的驰振力系数均大于0;与上表面中间位置的测点相比,上表面边缘位置测点的压力与升力和扭矩的相关性更强;上表面边缘位置测点的压力与升力和扭矩的相关性对风攻角的变化不敏感;随着风攻角的增大,上表面中间位置测点的压力与升力和扭矩的相关性显著增强。

斜拉桥结构模型试验索力测试方法研究

以某实验室独塔斜拉桥试验模型为研究对象,对斜拉桥模型试验的索力测试方法展开研究。开发了一种基于压力环传感器的索力测试系统,基于ANSYS分析平台,按照接触问题对该系统进行了仿真分析。在此基础上,在实验室模型桥上,采用测频法对该系统进行了对比验证。结果表明：该系统操作简单,性能可靠,测试精度较高,在不改变斜拉索刚度的情况下可以实现斜拉桥模型试验中斜拉索索力的实时、长期监测。     

规训的教育与人的自由

教育的本意应是培养人的自由心智,提升人的内在德性,而学校则是实现这一目的的重要场域。但是现在的学校越来越成为一个规训的场所,教育则沦落成一个代替强势进行规训的工具。这种异化现象已使得教育在偏离自己方向的道路上越走越远。教育成为一种“制器”的工具而不再是一种“育人”的活动,这必然导致教育的工业化生产和人的尊严与自由的丧失。     

Adaptation and Validation of the Polymorphous Prejudice Scale (PPS) - A Short Form In a Sample of Heterosexual Chilean College Students

ABSTRACT. Objectives: The purpose of this article is to present the psychometric characteristics of a short form of the Polymorphous Prejudice Scale (PPS; Massey, 2009), which was adapted and validated in a heterosexual Chilean population. PPS is a multidimensional measure of sexual prejudice. Methods: A nonprobabilistic (convenience) sample consisted of 422 college students. Results: Findings reveal a shortened 16-item form, grouped in four subscales, with all of the items referring to new forms of sexual prejudice. The findings showed differences based on gender, religiosity and geographic location, as hypothesized. Conclusions: Results are discussed in relation to the strengths and weaknesses of the short form of the PPS.
