中国工业经济绩效的实证研究——基于36个行业的面板数据

该文利用1993-2008年的36个工业行业的面板数据,通过固定效应模型,实证研究了工业行业的经济绩效与影响因素之间的关系。研究结果表明,提高工业行业的经济绩效关键在于行业效率和市场需求。从分行业的角度看,影响行业绩效的因素与生产型行业和消费型行业的行业特征有关。根据该文的研究表明,对于某些行业,试图通过兼并或重组等方式扩大行业规模、提高行业产值和行业集中度的做法来提高行业绩效,有可能适得其反。     

我国地方政府环境治理绩效分析

随着我国的生态资源环境压力持续增加,环境污染事件频发,我国地方政府的环境治理已经初见成效,但也存在着环境治理低效率的问题。多种原因导致了地方政府环境治理低效。地方政府可以从完善环境考核等方面加强地方环境治理。     

Characterization and dating of blue ballpoint pen inks using principal component analysis of UV-Vis absorption spectra, IR spectroscopy, and HPTLC

The ink of pens and ink extracted from lines on white photocopier paper of 10 blue ballpoint pens were subjected to ultraviolet-visible (UV-Vis) spectroscopy, infrared (IR), and high-performance thin-layer liquid chromatography (HPTLC). The R(f) values and color tones of the bands separated by thin-layer chromatography (TLC) analysis used to classify the writing inks into three groups. The principal component analysis (PCA) investigates the pen responsible for a piece of writing, and how time affects spectroscopy of written ink. PCA can differentiate between pen ink and ink line indicates the influence of solvent extraction process on the results. The PCA loadings are useful in individualization of a questioned ink from a database. The PCA of ink lines extracted at different times can be used to estimate the time at which a questioned document was written. The results proved that the UV-Vis spectra are effective tool to separate blue ballpoint pen ink in most cases rather than IR and HPTLC.     

建设我国地方政府绩效管理制度的几点思考

在西方新公共管理运动的冲击下,我国政府绩效管理问题也开始引起理论界和实务界的重视。随着上世纪90年代以来的目标责任制、干部考核等评估办法的推行,绩效管理的理念已逐渐深入到我国各级政府部门的管理实践中,绩效管理制度的建设已经成为我国政府行政管理创新的重要内容。本文以地方政府绩效管理制度的系统性建设为切入点,对其完善提出相关的建议。     

PARENTAL INVOLVEMENT IN THE CRIMINAL JUSTICE SYSTEM AND THE DEVELOPMENT OF YOUTH THEFT,MARIJUANA USE,DEPRESSION, AND POOR ACADEMIC PERFORMANCE*

Explanations for the fact that crime tends to run in families have focused on the deprived social backgrounds of criminal parents, methods of child‐rearing, modeling processes, and genetic mechanisms. However, parental involvement in the criminal justice system itself also might contribute to the intergenerational transmission of crime and have other adverse effects on children's well‐being. We investigated the development of youth problem behavior in relation to parental arrest, conviction, and incarceration in the youngest and oldest samples of the Pittsburgh Youth Study, a longitudinal survey of 1,009 inner‐city boys. Parental arrest and conviction without incarceration did not predict the development of youth problem behavior. Parental incarceration was not associated with increases in marijuana use, depression, or poor academic performance. However, boys experiencing parental incarceration showed greater increases in theft compared with a control group matched on propensity scores. The association between parental incarceration and youth theft was stronger for White youth than for Black youth. Parenting and peer relations after parental incarceration explained about half of its effects on youth theft. Because the effects of parental incarceration were specific to youth theft, labeling and stigma processes might be particularly important for understanding the consequences of parental incarceration for children.     

涤纶纤维上分散染料的液-质分析

目的建立液-质联用技术对涤纶纤维上分散染料进行分析的方法。方法以N,N-二甲基甲酰胺为提取剂,在负离子模式下对12个黄色涤纶纤维上分散染料进行分析。结果12种分散染料在负离子模式质谱检测条件下均得到了有效的分析。根据一级负离子模式下总离子流图中准分子离子峰质荷比的不同,可将其中8种样品一一鉴别开。在此基础上,从染料离子化产物中选取响应信号较强的准分子离子为母离子,再对母离子进行二级质谱全扫描,依据二级质谱图中特征碎片峰的数目、质荷比的异同可对纤维上染料进一步进行鉴别。结论液-质联用法是检验有色纤维上染料的一种科学、有效的方法。     

Explaining Majority and Minority Trust in the Police

This article tests the contribution that social capital theory, performance theory, and the procedural justice-based model can make towards explaining the trust of majority and minority group members in the police. The central research questions are: (1) do the same factors determine their levels of trust? and (2) are the effects parallel? To answer these questions, we carried out regression analyses on data collected from majority and minority group members living in Belgium (960 face-to-face interviews). The results show that, although the three theories offer explanatory elements for members of both majority and minority groups, the explanation of their trust in the police is not identical. Implications for research and theorization are discussed.     

论现代绩效管理方法对工会企事业管理的启示

平衡记分卡是二十世纪末由美国哈佛商学院教授罗伯特·卡普兰和诺顿研究所所长戴维·诺顿共同设计的一套考核工具和绩效管理方法,经过国內外一些企业的实践尝试,证明其在促进短期经济增长和实现长远价值和利益的结合上发挥着重要作用,目前在国內已愈益成为备受企业青睐的一套现代管理体系。工会企事业如何在日益激烈的市场竞争中站稳脚跟并发展壮大,以平衡记分卡为原理的绩效管理方法提供了一种现代管理思维和启示。     

上市公司股权结构、股东行为与治理绩效问题实证分析

本文利用上市公司年报数据分析描述了上市公司股权构成、股权集中度、股东行为的特征,并在此基础上验证了三者与公司绩效之间关系的研究假设。结果表明,国家股、法人股没有表现出其与公司绩效的显著相关关系;流通股对公司绩效也不存在显著的相关关系。股权集中程度越高公司绩效越差。股东参与公司治理的积极性与公司绩效之间存在正相关关系。
