公共理性：现代执政党伦理建设的理性基础

公共理性是现代公共行政的理性基础,现代公共行政中,政府的责任就是提供公共利益.执政党通过政策的制订与对政府行为的监督对政府进行领导,所以就必须和政府一样具有公共理性的能力.同时,公共理性作为现代民主政治生活的理性,与现代执政党的伦理诉求有着内在的一致性.

迎接形象力的时代

当今世界,形象力日益成为商战取胜的关键。优美的品牌形象是企业巨大的财富。形象经营是一项长期的战略使命,必须持之以恒。一个经得起时间考验的品牌形象往往具有文化性,当今流行的CIS策略是塑造企业个性化的优美形象的很好办法。一个企业和品牌形象的塑造,是一个漫长,渐进、艰辛的过程,是一代又一代企业人智慧和心血的结晶。期望在民族工业的每一领域都有若干形象优美,品质一流的企业和品牌,成为民族经济的柱石。     

对房价——收入衡量指标的修正

针对房价收入比指标衡量区域房地产价格与居民收入水平关系中的不足,提出人均住宅有效购买力系数的概念,阐述该指标的优点,并用该指标对1987年以来中国人均住宅有效购买力的变化和截止2004年底37个大中城市人均有效购买力的横向对比做了实证分析,进而探讨了建构中国房地产市场统计指标体系的新思路。

在系统介绍西方国家电力监管立法的基础上,就西方国家在电力监管立法的基本意义、价值目标和基本模式、内容等进行了全面分析,从中总结出了电力监管立法要注意制定监管规则、保持监管之独立性,以及支持竞争保持中立等对我国具有重要借鉴意义的若干经验。     

学术期刊的编辑失范与价值回归

学术期刊的编辑失范是学术失范乃至学术腐败现象的助产士。失察、徇私、畏势、缺纠等编辑失范现象的危害是严重的,它使学术创新本质异化,降低了学术期刊的公信力,损害了编辑作为学术把关人的形象,进一步恶化了学术风气。要实现学术期刊的价值回归,必须治理编辑失范。其治理途径是:营造谴责编辑失范现象的舆论氛围,加强编辑自律,实现制度治理,从净化小环境做起,共同建设健康的学术大环境。     

Intergroup Behaviour and Ethnicity: A Social Psychological Perspective

Humans exist not only as unique individuals, but also as members of social groups that are formed on the basis of ethnicity, gender, age and so forth. Reflecting this duality are interpersonal and intergroup modes of behaviour, respectively. Thus, humans can act in terms of their personal self and treat others as individuals (interpersonal behaviour); they can also act in terms of group membership and relate to others as members of this or that group (intergroup behaviour). In a mixed marriage, for example, the couple's behaviour toward each other is ‘normally’ interpersonal, but can become intergroup when war breaks out between their respective ethnic groups. Contrary to common sense, factors more minimal than a war are often sufficient to trigger intergroup behaviour. Indeed, seemingly interpersonal encounters are in fact intergroup. How does behaviour shift from interpersonal to intergroup, and with what consequences? To address these questions, I outline a social psychological perspective based on social identity theory and conclude with a discussion on the enigmas of ethnicity.     

Asymptotic Normality in Mixtures of Power Series Distributions

Abstract.  The problem of estimating the individual probabilities of a discrete distribution is considered. The true distribution of the independent observations is a mixture of a family of power series distributions. First, we ensure identifiability of the mixing distribution assuming mild conditions. Next, the mixing distribution is estimated by non-parametric maximum likelihood and an estimator for individual probabilities is obtained from the corresponding marginal mixture density. We establish asymptotic normality for the estimator of individual probabilities by showing that, under certain conditions, the difference between this estimator and the empirical proportions is asymptotically negligible. Our framework includes Poisson, negative binomial and logarithmic series as well as binomial mixture models. Simulations highlight the benefit in achieving normality when using the proposed marginal mixture density approach instead of the empirical one, especially for small sample sizes and/or when interest is in the tail areas. A real data example is given to illustrate the use of the methodology.
