论司法公开的必要限度--以副卷制度为着眼点分析

我国提出“司法公开”的口号已有很多年了,国内外关于司法公开问题的研究也比比皆是,已经达到了相对成熟的程度。然而,就关于法院案卷的副卷公开问题,研究者却是少之又少。副卷制度的存在,在给司法活动提供便利的同时,也引发了诸多问题。诱发了法院通过上下级领导请示“暗箱”操纵审判结果,或其它机关不当干预司法等现象,破坏司法公正和权威。而副卷制度的存在,形成了巨大“保护伞”,并将这些行为彻底地掩盖起来。因此,副卷制度所衍生出的问题亟需人们深刻反思。随着我国“司法公开”的不断推进,及时发现副卷制度的弊病,并对其进行合理的改造,有助于确保司法真正地在阳光下运行,提升司法运行的社会效果。     

Cultural capital or relative risk aversion? Two mechanisms for educational inequality compared1

In this paper we empirically examined two explanatory mechanisms for educational inequality: cultural reproduction and relative risk aversion, using survey data taken from secondary school pupils in Amsterdam. Cultural reproduction theory seeks to explain class variations in schooling by cultural differences between social classes. Relative risk aversion theory argues that educational inequalities can be understood by between-class variation in the necessity of pursuing education at branching points in order to avoid downward mobility. We showed that class variations in early demonstrated ability are for a substantial part cultural: cultural capital - measured by parental involvement in highbrow culture - affected school performance at the primary and secondary level. However, relative risk aversion - operationalized by being concerned with downward mobility - strongly affects schooling ambitions, whereas cultural capital had no effect. Thus, we conclude that 'primary effects' of social origin on schooling outcomes are manifested through cultural capital and not through relative risk aversion (in addition to other potential sources of class variations such as genetics). Relative risk aversion, and not cultural capital, affects schooling ambitions, which is relevant for our understanding of secondary effects.     

在农村落榜生中普及中等职业教育的意义及对策

中、高考落榜生已经成为当代农村青少年的主体.他们在应试教育环境下完成学业,缺乏新型农村、工业化和城镇化建设的相应知识和技能,难以顺利就业、创业和长足发展.应该根据社会发展需要,通过普及职业教育,提高农村落榜生的综合素质,从而促进农村青少年的整体发展.只要适当扩大职业教育的规模,不断提高职业教育的质量,相应加大职业院校农村学生的资金扶助,我国就能在短期内普及农村落榜生中等职业教育.     

Analysis of child labour in Peru and Pakistan: A comparative study

This paper analyses child labour participation and its key determinants using data sets from Peru and Pakistan. The results include tests of the ‘Luxury’ and ‘Substitution’ hypotheses that play key roles in recent studies on child labour and child schooling. The results reject both hypotheses in the context of child labour in Pakistan and suggest that income and related variables do not have the expected negative effect on children's work input. Rising wages of adult female labour in Pakistan, and falling adult male wage in Peru lead to increased participation of children in the labour market. The results on the combined country data formally establish the presence of strong individual country effects in the estimated regressions. For example, ceteris paribus, a Peruvian child is more likely to experience schooling than a Pakistani child. However, both countries agree on the positive role that adult female education and infrastructure investment in basic amenities can play in discouraging child labour and encouraging child schooling.

Personal income taxation under mobility, exogenous and endogenous welfare weights, and asymmetric information

This paper analyses how governments should tax labour income accruing to a group of highly skilled and geographically mobile individuals who divide their time or career between several jurisdictions. The analysis differs from previous models on migration and taxation by addressing optimal regulation when agents work for several principals. Optimal taxation is developed for social welfare functions with exogenous and endogenous welfare weights. Marginal income taxes are applied for screening purposes, and the rates are lower with endogenous than with exogenous welfare weights. Received: 22 January 1998/Accepted: 3 July 1999)     

An omnibus two-sample test for ranked-set sampling data

We develop an omnibus two-sample test for ranked-set sampling (RSS) data. The test statistic is the conditional probability of seeing the observed sequence of ranks in the combined sample, given the observed sequences within the separate samples. We compare the test to existing tests under perfect rankings, finding that it can outperform existing tests in terms of power, particularly when the set size is large. The test does not maintain its level under imperfect rankings. However, one can create a permutation version of the test that is comparable in power to the basic test under perfect rankings and also maintains its level under imperfect rankings. Both tests extend naturally to judgment post-stratification, unbalanced RSS, and even RSS with multiple set sizes. Interestingly, the tests have no simple random sampling analog.
