THE PARTICIPATION DIVIDE: Content creation and sharing in the digital age

This paper looks at the prevalence of creative activity and sharing in an age when the barriers to disseminating material have been considerably lowered compared with earlier times. The authors use unique data to explore the extent to which young adults create video, music, writing and artistic photography, as well as the prevalence of sharing such material online. Findings suggest that despite new opportunities to engage in such distribution of content, relatively few people are taking advantage of these recent developments. Moreover, neither creation nor sharing is randomly distributed among a diverse group of young adults. Consistent with existing literature, creative activity is related to a person's socioeconomic status as measured by parental schooling. The novel act of sharing online, however, is considerably different by gender with men much more likely to engage in it. However, once internet user skill is controlled for, men and women are equally likely to post their materials on the Web.

对我国经济增长中出现的投资需求主导化趋势分析

伴随着经济的高速增长,我国的投资率不断上升。在总需求的构成中,投资需求已经取代消费需求成为拉动经济增长的主导因素。过高的投资率让我国的经济增长过分依赖固定资产的投资,加剧经济大幅度波动的风险。在这种经济模式中政府更容易通过控制投资来影响经济的运行,但却削弱市场机制的本身作用,同时中央政府和地方政府更容易产生利益的博弈。我国特有的投资体制以及地方政府追求经济发展速度最大化的目标是造成这种现象的根源,如果不改变,我国经济增长方式的转变以及经济的可持续发展将会更加困难。     

汤普森“文化唯物主义”的理论与范式

作为理论的"文化唯物主义"是汤普森在探索马克思主义英国化过程中,基于自己对斯大林主义的批判反思和历史研究实践,形成的一种主要适用于自由资本主义时代的历史唯物主义学说。作为范式的"文化唯物主义"是奠基在"自下而上"的观察视角、"人民历史"观念和超越资本主义的乌托邦议程这三个支撑点上的,它具有两种基本作用:真实的经验整体的倾听和再创造;大众文化的社会功能的分析与评价。

Estimating ordered parameters by linear programming

There are many models that require the estimation of a set of ordered parameters. For example, multivariate analysis of variance often is formulated as testing for the equality of the parameters versus an ordered alternative. This problem, referred to as isotonic inference, constrained inference, or isotonic regression, has led to the development of general solutions, not often easy to apply in special models. In this expository paper, we study the special case of a separable convex quadratic programming problem for which the optimality conditions lead to a readily solved linear complementarity problem in the Lagrange multipliers, and subsequently to an equivalent linear programming problem, whose solution can be used to recover the solution of the original isotonic problem. The method can be applied to estimating ordered correlations, ordered binomial probabilities, ordered Poisson parameters, ordered exponential scale parameters, or ordered risk differences.     

应对消费文化时代的文艺理论新课题

当代中国审美文化实践正在发生着深刻的变化,传统的带有形而上特征的审美活动正从孤立的时空中走出来,融入到更为广阔无限延展的日常生活中,文化产品也更多地带有了商品属性成为普遍的消费品。这些都给文艺理论在新世纪的建设提出了许多新的问题。文章试从文艺观的调整、知识立场的反思、批评对象的拓展以及批评平台的拓宽这四个方面对消费时代的文艺理论的建设问题予以回应。     

A graphical summary of disparities in health care and related summary measures

In order to assess the effectiveness of government programs designed to reduce disparities in the health care minority groups receive relative to the majority white population, a proper statistical measure should be used. This article proposes a measure of and its accompanying graph, which is readily interpretable and is not affected by the number of minority subgroups examined.     

奢华生活里的奢侈品——一场风花雪月的营销

奢侈品是一种超出人们生存与发展需要范围的、具有独特、稀缺、珍奇等特点的消费品，又称为非生活必需品。文章对我国历史上奢靡的消费现象进行了回顾，提出奢侈消费对拉动我国未来经济增长有其积极作用。随着中国经济的快速成长，奢侈品消费时代已悄悄来临。如何把握消费者的消费心理、消费行为，怎样适应中国的奢侈品消费市场，采取适合的营销对策，是一个值得我们深思的问题。
