论循环经济条件下建筑材料的开发与利用

在总结建筑材料开发与利用现状及存在的问题并深入分析其原因的基础上,遵循循环经济"减量化、再使用、再循环"的3R原则,从转变观念意识、加强科技创新、致力体制改革、严格管理等方面,提出了建筑材料开发与利用的对策。     

托尼的中国研究及对费孝通乡村研究的影响

托尼的社会学研究在国内学术界被低估甚至被忽视了,他对中国的研究是经得起时间的考验的,也影响了当时中国学者的研究,典型的是费孝通的乡村研究,很大程度上是受到托尼的直接或间接影响。而托尼与费孝通共同的研究传统就是历史视角、整体视角,在此基础上研究中国农村,无论是从一般学术意义上,还是具体的中国当前农村问题的研究上,都具有很大的指导意义和参考价值,继承和发扬这一研究传统,是文化自觉和理论自觉的重要途径。     

A Bayesian estimate of the concordance correlation coefficient with skewed data

Concordance correlation coefficient (CCC) is one of the most popular scaled indices used to evaluate agreement. Most commonly, it is used under the assumption that data is normally distributed. This assumption, however, does not apply to skewed data sets. While methods for the estimation of the CCC of skewed data sets have been introduced and studied, the Bayesian approach and its comparison with the previous methods has been lacking. In this study, we propose a Bayesian method for the estimation of the CCC of skewed data sets and compare it with the best method previously investigated. The proposed method has certain advantages. It tends to outperform the best method studied before when the variation of the data is mainly from the random subject effect instead of error. Furthermore, it allows for greater flexibility in application by enabling incorporation of missing data, confounding covariates, and replications, which was not considered previously. The superiority of this new approach is demonstrated using simulation as well as real‐life biomarker data sets used in an electroencephalography clinical study. The implementation of the Bayesian method is accessible through the Comprehensive R Archive Network. Copyright © 2015 John Wiley & Sons, Ltd.     

Ethnic differences in the academic achievement process in Canada

This research examines the extent to which differences in achievement between German-speaking and French-speaking students are accounted for by theoretically related intervening variables and the extent to which the entire achievement process differs across the two ethnic groups. For the two ethnic groups, both main effects and interaction effects have significant consequences for the academic achievement process, even when a number of other variables are controlled. The results suggest that the whole process works to the benefit of the German-speaking students and to the detriment of the French-speaking students.     

Resources,homophily, and dependence: Organizational attributes and asymmetric ties in human service networks

This paper examines the effects of organizational attributes on power/dependence relations in interorganizational dyads. Exchange and homophily theories are discussed as two alternative perspectives on the processes that give rise to such effects. The data pertain to interagency ties in three community-based networks of youth service agencies and are analyzed via a new strategy of linear modeling dyadic relations. The results of the analysis suggest that size, administrative position, and justice system connections condition the extent to which an agency initiates and receives ties of influence, assistance, and support. Moreover, these relations are more frequent between agencies with similar treatment ideologies and client racial makeup. Finally, size and justice system access are found to reduce agency dependence on a network's administrative core. In the course of the discussion, a number of related issues and findings are discussed.     

Durkheim and pierce on suicide and economic change

This paper is an attempt to build upon Pierce's important finding, a confirmation of Durkheim, that any form of economic disruption or change increases suicide. In this paper, certain aspects of Pierce's method are criticized. The analysis of an expanded and updated data set, using analytic techniques designed for time-series data, suggests that economic disruption per se is not as relevant to the suicide rate as are economic hardship and economic deterioration or improvement.     

列文森与中国近代思想史研究

列文森是美国 2 0世纪五六十年代中国学研究领域最主要的学术代表之一 ,美国中国近代思想史研究领域的开拓者和领导者。本文主要对列文森的两部学术代表作———《梁启超与近代中国的心灵》和《儒教中国及其现代命运》(三卷本 )进行剖析 ,并对列文森的研究特点作了考察 ,认为他浓厚的“犹太情结”对其中国近代思想史研究有深刻影响 ;他的历史研究具有较为明显的历史相对主义倾向 ,他在阐述问题时喜欢用二分法 ,他有着强烈、深刻的问题意识。     

FDI和R&D对经济增长的动态影响———基于中国20年面板数据的实证分析简

本文采用1991－2010年我国省际面板数据,分别从整个样本期、1991－2000年、2001－2010年考察了 FDI和 R＆D对我国经济增长的动态影响。实证结果表明,R＆D对我国经济增长的贡献经历了一个从不显著到显著的正影响过程,而且R＆D对我国经济增长的贡献大于FDI;尽管在整个样本期FDI对我国经济增长的影响显著为正,但由于外资企业对我国国内企业竞争负效应的增强和技术外溢效应的减弱,使得 FDI 对我国经济增长的贡献由1991－2000年的显著正影响转为2001－2010年的不显著负影响。因此,我国需要积极鼓励国内企业以跨国并购的方式走出去,积极与外国 R＆D机构开展合作,提升我国企业的技术水平和 R＆D实力,扭转近年来 FDI在我国经济增长中的负效应局面。     

广东入境旅游规模差异及其演变趋势研究

文章以广东省21个地市的2002-2013年共12年的入境旅游人数为样本数据,运用位序规模理论,标准差(VOC)、基尼系数(G)以及赫芬达尔系数(Hn)等计量指标,以及分形理论的R/S分析法依次分析了广东省入境旅游规模分布现状、区域差异化程度及未来入境旅游规模的演化趋势,得知广东省入境旅游规模呈高度首位型分布、区域间差异化较为明显且集聚程度下降,其入境旅游规模将在未来一段时间内持续扩大。     

Comments on Montague J. Lord's “distributional effects of international commodity price stabilization: Do the aggregate gains apply to individual producing countries?” [JPM 3:61–75 (1981)]

Lord discusses the impact of international commodity price stabilization on Latin American producing country export revenues. He correctly emphasizes that the directions and magnitudes of such effects may vary substantially across producers, depending on the degree of segmentation of the commodity markets and the nature and distribution of the shocks. However his potential contribution may be lost because of a number of inaccuracies, which I discuss under three general topics.
