论艾伦·伍德对资本主义民主的批判

艾伦·伍德基于历史唯物主义对经济和政治的连续性的分析,以民主为切入点,借鉴古雅典经济民主和政治民主相统一的洞见,揭示了资本主义民主的虚假性。伍德的观点既有助于我们认识资本主义民主的本质,也有助于我们从经济民主和政治民主相统一的维度重新思考社会主义民主,建构社会主义民主制度。     

Affiliation networks with an increasing degree sequence

Affiliation network is one kind of two-mode social network with two different sets of nodes (namely, a set of actors and a set of social events) and edges representing the affiliation of the actors with the social events. Although a number of statistical models are proposed to analyze affiliation networks, the asymptotic behaviors of the estimator are still unknown or have not been properly explored. In this article, we study an affiliation model with the degree sequence as the exclusively natural sufficient statistic in the exponential family distributions. We establish the uniform consistency and asymptotic normality of the maximum likelihood estimator when the numbers of actors and events both go to infinity. Simulation studies and a real data example demonstrate our theoretical results.     

苏州民营快递的用户满意度调查分析

近年来,随着网络购物的迅速发展,快递行业已成为人们日常生活中的重要组成部分.面对激增的快递压力,快件的准确性以及良好服务成为社会关注的重点.运用统计分析方法对苏州民营快递用户满意度影响因子进行分析,结果表明,快递用户满意度最高的四个因素依次是“价格水平”、“服务周期”、“收费标准”和“用户体验”；最重视的四个因素依次是“配送效率”、“服务水平”、“物品安全”和“品牌建设”；而对“信息系统”、“投递服务”、“管理制度”和“网点覆盖”四个因素则感到不满意.苏州民营快递企业需要改进完善的环节主要集中在服务质量、企业品牌、用户感知和基础设施等方面.     

MATERIALISTIC VALUES IN HONG KONG AND GUANGZHOU: A COMPARATIVE ANALYSIS OF TWO CHINESE SOCIETIES

This article integrates two competing perspectives on value orientation. Inglehart's postmaterialism thesis stresses the permanent effects of childhood experience in which economic deprivation leads to materialism in adult life. The human development perspective, in contrast, emphasizes the evolution of a person's value system as life-cycle development unfolds new circumstances and possibilities. We adopt a developmental framework to test claims from these two perspectives. On the basis of micro-level data, we compare the materialistic values of two historically and culturally different Chinese societies, Hong Kong and Guangzhou. Findings support Inglehart's assertions that childhood experience has lasting effects and that rapid social changes create birth cohort differences in materialistic concerns. But life-cycle developments, such as education, marriage, and current social status, are equally important in influencing a person's value orientation. Both perspectives see only part of the picture, and an integrated approach is needed to better understand how people construct and maintain their value system.     

金代文教政策的确立与实施

金代作为女真人建立的政权,是中国历史上一个重要时期.金代创立了独具特色的汉、女真两套并行的教育体系和科举体系.从“尊孔崇儒”和“发展女真文化”两方面对金代文教政策的研究,对于认识金代在中国教育史上占有的重要地位有着积极的意义.     

清代三山五园地区的买卖街

清朝时期,清帝陆续在三山五园地区修建皇家园林,到乾隆时期发展到了鼎盛阶段。为了满足帝后和皇室人员的好奇心、游赏玩乐需要,以及王公大臣的生活需要;同时,也为下层随侍人员提供了必要的物质补充和精神慰藉,清帝在三山五园中设立民间市肆——买卖街。从园林艺术角度看,买卖街的设立也是园林造景的需要。买卖街的建筑风格,既有仿照江南苏州市肆格局的苏州街,又有典型的北方市肆风格的买卖街,集中体现了当时北方文化与南方文化相互融合的皇家园林风格。      

结构优化对我国农产品出口竞争力的影响

应用产业组织理论,揭示结构优化对农产品国际竞争力的作用机理。以RCA衡量农产品出口竞争力并建立多元回归模型,在有效分离工资、土地灌溉面积和汇率等因素后,实证研究发现技术结构对农产品出口竞争力有显著正向影响。当前经济背景下,提升农产品出口竞争力的政策思路,需从传统的要素禀赋优势转移到结构优化的轨道上来。优化农产品出口结构,政府需加大对高附加值农产品在生产、流通、出口等环节的支持力度,营造寡占的农产品市场结构,鼓励和扶持创意农业的发展。     

Collective versus Individual Effects in Survival Analysis of Multiple Failures

In survival analysis, we sometimes encounter data with multiple censored outcomes. Under certain scenarios, partial or even all covariates have ‘similar’ relative risks on the multiple outcomes in the Cox regression analysis. The similarity in covariate effects can be quantified using the proportionality of regression coefficients. Identifying the proportionality structure, or equivalently whether covariates have individual or collective effects, may have important scientific implications. In addition, it can lead to a smaller set of unknown parameters, which in turn results in more accurate estimation. In this article, we develop a novel approach for identifying the proportionality structure. Simulation shows the satisfactory performance of the proposed approach and its advantage over estimation under no assumed structure. We analyse three datasets to demonstrate the practical application of the proposed approach.     

土地股份合作社内部能形成利益联结机制吗？

土地股份合作社在促进资本与农地结合,实现小农户与现代农业衔接上具有独特优势。通过对普通社员与核心社员在土地股份合作社不同发展阶段的可选策略的讨论,分析合作社不同发展阶段利益联结机制的特征,并对黑龙江省齐齐哈尔市克山县仁发合作社的利益联结机制进行案例研究后提出:土地股份合作社坚持“退社自由”原则有利于保护普通社员的基本权益,但不利于在合作社内部形成“风险共担”机制,要在保证普通社员基本权益的同时建立“利益共享、风险共担”的利益联结机制,应该充分利用计提公积金这一手段,不允许社员退社时退回公积金或许是有利于土地股份合作社内部形成“风险共担”机制的一个可尝试的方法。
