Species richness,phylogenetic and functional structure of bird communities in Chinese university campuses are associated with divergent variables

University campus is an important component of urban landscapes for biodiversity conservation. However, to our knowledge no study has quantitatively assessed the diversity and structure of bird communities in Chinese university campuses, especially from phylogenetic and functional perspectives. Here, for the first time we linked species richness, phylogenetic structure and body mass structure of campus bird communities with contemporary climate, glacial-interglacial climate change, altitudinal range, population density around campus, area and age of campus to test their associations. We found 393 bird species in 38 university campuses (29% of all Chinese bird species, two species are endangered, four species are vulnerable, and 33 species are near threatened). The variables significantly correlated with campus bird species richness, phylogenetic structure and body mass structure were altitudinal range and mean annual precipitation, glacial-interglacial anomaly in temperature, and altitudinal range, respectively. In particular, there were more species in steeper and wetter campuses, more young species clustered in campuses with stable glacial-interglacial climate, and more species with smaller body size in steeper campuses. Our study highlights the importance of considering both phylogenetic and functional information for biodiversity conservation in urban ecosystems.     

民营企业工会建设研究

民营企业建立工会组织以协调劳动关系和谐成为我国工会发展的工作重点。实践中民营企业工会建设存在组建工作力不从心、“工会热，政府冷”现象比较突出、民企职工权益受侵害现象大量存在、工会维权形式主义较为严重的问题。加强完善民营企业工会建设势在必行。

文章例举明代徽州黄氏刻工为主的徽州刻工移居武林的情况,论证明代万历年间徽派版画对武林版画的影响以及武林版画在吸收徽派版画的基础上所形成的新的风格样式。     

论我国反垄断审查机制的得失——以松下收购三洋案为切入点

从松下收购三洋案的审查过程可以看出,我国反垄断审查机制呈现"三多三少"的特点。商务部的审查决定汲取了以往我国反垄断审查的经验和教训,代表我国反垄断审查机制的最高水平。在肯定我国反垄断审查取得很大成绩的同时,不得不承认我国的反垄断审查机制还存在不少问题。只有正视问题,总结经验,我国的反垄断审查机制才能赶超国际先进水准,日臻成熟。

知识产权间接侵权之归责原则的探讨

知识产权间接侵权是指行为人没有实施直接侵犯知识产权的行为,但是却对直接侵犯知识产权的行为起到了诱导或者帮助的作用,从而法律规定应当承担责任的行为.我国的知识产权立法中没有关于间接侵权的规定,给司法实践带来了困惑.通过对国外知识产权间接侵权归责原则的评析以及对我国知识产权间接侵权的分析,认为知识产权间接侵权应当实行过错责任原则.     

企业环境管理动因分析

针对企业环境管理问题,采用定性分析和定量分析结合的方法,分析了环境管理的目标和环境管理动因,指出环境管理目标取决于企业的目标,企业环境管理的动因主要是利益驱动和社会责任。环境管理利益驱动目标和社会责任目标在许多方面是一致的,对于不一致地方,可以通过法律调节的同时,要求企业勇于承担社会责任。研究结果对企业环境管理有指导意义。     

A Conditional Approach for Regression Analysis of Longitudinal Data with Informative Observation Time and Non-negligible Observation Duration

Recently, there has been a great interest in the analysis of longitudinal data in which the observation process is related to the longitudinal process. In literature, the observation process was commonly regarded as a recurrent event process. Sometimes some observation duration may occur and this process is referred to as a recurrent episode process. The medical cost related to hospitalization is an example. We propose a conditional modeling approach that takes into account both informative observation process and observation duration. We conducted simulation studies to assess the performance of the method and applied it to a dataset of medical costs.
