全程体验式方法创新大学生思想政治教育的探究和实践

传统的大学生思想政治教育教法单一,不符合学生的身心特点和生活实际,不仅难以吸引学生,还容易引起他们的反感。而全程体验式教育却能割其弊端,可将它引入大学生思想政治教育。通过以全程教育代替节点性教育,创新大学生思想政治教育的时间观;以体验式教育代替灌输式教育,创新大学生思想政治教育的教育观;以形式多样的教育方法代替单一的教育方法,丰富大学生思想政治教育的载体;以个性教育代替共性教育,创新大学生思想政治教育的模式;以民主教育代替权威教育,创新大学生思想政治教育的话语权。     

American Public Opinion on Immigration: Nativist,Polarized, or Ambivalent?

For Dauvergne (2016), one consequence of the “end of settler societies” is nativism, or what she calls “mean-spirited politics”: anti-immigrant, anti-Muslim, anti-Multiculturalism. This accords with the prevailing tone of public opinion literature on the subject, which links anti-immigrant hostility in settler societies to influxes of diversity and associated racial threat. In this essay, we determine just how closely this stylized vision of anxiety-fuelled nativism resembles the true state of mass opinion about immigration. Using a variety of surveys fielded in recent years, we show that Americans: 1) hold generally positive views about immigration, though with a substantial dose of ambivalence about its consequences; 2) are not especially consistent in their policy attitudes over time; 3) express policy attitudes that readily depart from their underlying predispositions, and; 4) have only become more pro-immigrant in recent years, and whatever partisan polarization exists on the issue stems from the fact that Republicans are becoming more positive at a slightly slower pace than Democrats. All of this suggests that, while there is a hard core of ethnocentrism and "mean-spiritedness" in the U.S., the prevailing tone is much less negative than the standard portrayal assumes.     

GETTING INTO THE WEEDS: DOES LEGAL MARIJUANA ACCESS BLUNT ACADEMIC PERFORMANCE IN COLLEGE?

This paper examines the effect of legal access to marijuana on student performance stemming from a voter-approved initiative legalizing marijuana for those 21 and older in the State of Washington. Using panel data from a medium-sized public university, we use a within-student and within-class estimator to show that legalization reduces students' grades, with an effect size about one-half the impact of gaining legal access to alcohol. Consistent with how marijuana consumption affects cognitive functioning, we find that students' grades fall furthest in courses that require more quantitative skills. These effects are largely driven by men and low performers. (JEL I23, I18, K32)     

A Primer on Visualizations for Comparing Populations,Including the Issue of Overlapping Confidence Intervals

In comparing a collection of K populations, it is common practice to display in one visualization confidence intervals for the corresponding population parameters θ₁, θ₂, …, θ_K. For a pair of confidence intervals that do (or do not) overlap, viewers of the visualization are cognitively compelled to declare that there is not (or there is) a statistically significant difference between the two corresponding population parameters. It is generally well known that the method of examining overlap of pairs of confidence intervals should not be used for formal hypothesis testing. However, use of a single visualization with overlapping and nonoverlapping confidence intervals leads many to draw such conclusions, despite the best efforts of statisticians toward preventing users from reaching such conclusions. In this article, we summarize some alternative visualizations from the literature that can be used to properly test equality between a pair of population parameters. We recommend that these visualizations be used with caution to avoid incorrect statistical inference. The methods presented require only that we have K sample estimates and their associated standard errors. We also assume that the sample estimators are independent, unbiased, and normally distributed.     

On some properties of variable size simple random sampling and a limit theorem

This paper introduces a sampling plan for finite populations herein called “variable size simple random sampling” and compares properties of estimators based on it with results from the usual fixed size simple random sampling without replacement. Necessary and sufficient conditions (in the spirit of Hajek (1960)) for the limiting distribution of the sample total (or sample mean) to be normal are given.     

行政区域变更工作应当纳入法治的轨道

目前,我国许多地方正在进行行政区域变更工作。行政区域变更应当以三个有机统一原则为指导,特别是要注重依法办事,要增强行政区域变更工作的透明度,充分听取社会公众的意见,对于涉及公民权利的事项给予特别保护。为了进一步规范行政区域变更工作,应当充分发挥全国人大常委会和地方人大常委会通过行使重大事项决定权对行政区域变更工作的指导作用。此外,要真正将行政区域变更工作纳入法治轨道,应当适时制定和出台《中华人民共和国行政区划法》或者是《中华人民共和国行政区域变更法》,并草拟了《中华人民共和国行政区划法》专家建议稿,以此供学界进一步对此问题展开深入研究。

阿尔都塞和齐泽克意识形态理论之比较

阿尔都塞和齐泽克的意识形态理论都借鉴了拉康的思想，所以他们的思想存在着共同之处。区别在于阿尔都塞主要运用了拉康早期的镜像阶段的思想，齐泽克则主要运用了拉康晚期关于真实界的思想，由此出发，齐泽克认为阿尔都塞的质询理论并不彻底，他进一步发展了意识形态幻象理论。但是两者存在的问题也是共同的，一旦把意识形态的概念过度膨胀化，那么这个词也就失去了相应的意义。
