精致化纸浆模塑制品及关键制备工艺参数优化

为制备精致化纸浆模塑制品并研究关键加工工艺参数对其平滑度、光泽度的影响,以牛皮纸二次纤维为原料,在 全自动纸浆模塑机组上进行实际生产操作试验,用sPss软件进行极差分析和重复方差分析,对关键加工工艺参数进行 分析优化,得出较优的工艺参数为：打浆度25。SR、施胶剂用量1.5%、热压整型温度110℃和压力5 MPa。各参数影响 的主次顺序为：热压压力>打浆度>施胶剂用量>热压温度。研究表明提高热压压力,增加施胶剂用量,调节打浆度和 热压温度均可提高纸浆模塑制品的平滑度和光泽度     

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.     

Improving variance function estimation in semiparametric longitudinal data analysis

We propose an efficient and robust method for variance function estimation in semiparametric longitudinal data analysis. The method utilizes a local log‐linear approximation for the variance function and adopts a generalized estimating equation approach to account for within subject correlations. We show theoretically and empirically that our method outperforms estimators using working independence that ignores the correlations.

中等职业教育对厦门经济发展影响的实证研究

分析厦门经济特区成立以来中等职业教育与经济发展的关系，研究证明：中职的发展与第三产业的相关性最高；中职招生波动滞后于经济波动，而人才培养的周期性使得中职的毕业生在数量和质量上与经济的差距难以避免。中职应重点预测第三产业的发展趋势，超前培养技术人才，主动参与产业结构的优化升级，国家也应该注重灵活自主的社会职业培训机构。随着人们日益追求高层次的教育和初中阶段适龄青年的减少，中职即将进入逐步下降阶段，应该注重可持续发展，为将来部分条件好的中职院校升格高职院校预留条件。
