马克思恩格斯的劳资利益关系思想

近年来，随着非公有制经济的发展，非公有制领域就业人口的逐渐增多，劳资矛盾冲突问题越来越突出。劳资关系是马克思恩格斯研究的核心，通过分析资本对劳动的剥削理论，马克思恩格斯构建起来科学社会主义的理论大厦。马克思恩格斯的劳资关系思想主要包括劳资关系形成的基础、资本对劳动的剥削与劳资矛盾、资本对劳动的权力、资本积累收入差距、工会在劳资关系中的作用、世界市场与国际劳资关系等内容。     

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.     

A Unified Approach to Estimating and Testing Income Distributions With Grouped Data

We propose a unified approach that is flexibly applicable to various types of grouped data for estimating and testing parametric income distributions. To simplify the use of our approach, we also provide a parametric bootstrap method and show its asymptotic validity. We also compare this approach with existing methods for grouped income data, and assess their finite-sample performance by a Monte Carlo simulation. For empirical demonstrations, we apply our approach to recovering China's income/consumption distributions from a sequence of income/consumption share tables and the U.S. income distributions from a combination of income shares and sample quantiles.

Semiparametric partially linear varying coefficient models with panel count data

This paper studies semiparametric regression analysis of panel count data, which arise naturally when recurrent events are considered. Such data frequently occur in medical follow-up studies and reliability experiments, for example. To explore the nonlinear interactions between covariates, we propose a class of partially linear models with possibly varying coefficients for the mean function of the counting processes with panel count data. The functional coefficients are estimated by B-spline function approximations. The estimation procedures are based on maximum pseudo-likelihood and likelihood approaches and they are easy to implement. The asymptotic properties of the resulting estimators are established, and their finite-sample performance is assessed by Monte Carlo simulation studies. We also demonstrate the value of the proposed method by the analysis of a cancer data set, where the new modeling approach provides more comprehensive information than the usual proportional mean model.     

新形势下将党组织政治优势内化为国有企业核心竞争力的实践与思考

国有企业设立党组织，不仅有利于巩固党的执政基础，同时有利于提升国有企业的核心竞争力。国有企业党组织在掌握政策理论、队伍建设、组织纪律、群众工作以及思想政治工作等方面具有强大的优势，这种优势与企业中心工作相结合，就可以内化为国有企业独有的核心竞争力，成为推动企业发展的不竭动力源泉。
