The Competitive Impact of Targeted Television Advertisements Using DVR Technology

Digital video recorders (DVRs) are an emerging technology that is fundamentally changing the competitive landscape in industries that advertise on television. Perhaps the most familiar impact of DVR technology is that it enables consumers to avoid advertisements (ads) by fast forwarding through them. However, this “zipping” of ads is only one aspect of the impact of DVR technology. DVRs also collect a wealth of information at the consumer level that can be used by firms to target their ads more effectively. We examine how this targeting capability moderates the impact of ad avoidance in a competitive setting. Insights are provided on how best to manage this emerging technology in terms of the key managerial decisions of product pricing and advertising efforts, as well as its impact on profits in a competitive (duopoly) marketplace.     

时间概念的历史与被叙述的时间

很少有人从时间观的变化概括哲学思考的历史,但事实上,哲学史也是时间概念变化的历史,而这种变化,最明显地体现在文本书写形式的变化,即一切叙述都是关于时间的叙述,是以时态或不同类型的语句之间的各种连接形式构成的。一般来说,在哲学领域,时间概念的历史有两条基本的线索:其一是以亚里士多德为代表的,强调时间是世界的运动形式而不是心理的活动方式;另外一条线索,也就是本文着重分析的,是从奥古斯丁、胡塞尔、海德格尔到普鲁斯特,强调时间是“精神”的某种膨胀和收缩,与世界上正在运动着的某样东西无关。整个20世纪的欧洲哲学与文学艺术运动的主流,都与第二条线索有密切关系。至于康德的时间观,则属于这两条线索之间的中间派。本文特别把以上提到的两条时间线索,分别称为“纵向的时间观”与“横向的时间观”,前者从时间之外的对象中获得时间的解释,后者则是一种非对象化的时间概念,或者称为“彼在”、“异域”。     

Personality and Subjective Well-Being: Evidence from South Korea

Although the statistically significant relationship between personality traits and subjective well-being (i.e., self-reported happiness and life satisfaction) is well-known in the field of positive psychology, some scholars still cast doubt on the external validity of this finding and the strength of personality dimensions vis-à-vis other individual-level determinants of subjective well-being such as income, employment status, marital status, self-reported health, and so on. Using a nationally representative, face-to-face survey fielded in South Korea in 2009, we find that personality traits (measured by the Five-factor Model)—particularly, Emotional Stability and Extraversion—are positively associated with happiness and life satisfaction, after controlling for other covariates. The effects of personality traits are often on par with, and sometimes even greater than, those of other well-known determinants.     

How to Evaluate Government Performance while Building a Rule of Law Government in China*

Building a law-based government is a central element of the comprehensive framework for promoting the rule of law in China, while using evaluation to catalyze growth is in line with the incentive principle of management studies. Since China started to implement reform and opening up over thirty years ago, rule of law development and organizational evaluation have gone through several stages, each with different characteristics. Efforts to build a law-based government have met with success, but what the country now has is essentially still goal-oriented assessment. At present, this suffers from the lack of a clear goal orientation or definition of functions, an imperfect technical system and unsound motivation mechanisms, not to mention the practical problems of each government department going its own way, duplicating evaluations or being left rudderless. Drawing on a combination of value rationality and instrumental rationality and using government performance evaluation to promote the building of a law-based government not only conforms to the spirit of the rule of law and value rationality in government performance, but also strengthens the role of evaluation as an instrument for organizational management. Therefore, we need to create new evaluation theories, expand public participation, introducing diversified evaluating entities, improve technical systems, strengthen institutional buildup, and foster a performance-based culture. In addition, replacing goal-oriented assessment with performance evaluation will help the emergence of a new discipline—the performance evaluation of rule of law government, thus promoting multidisciplinary efforts to integrate and create new public administration theories in China.

Child Poverty in Rural China: Multidimensional Perspective

This paper describes a pilot study on child multidimensional poverty in rural China by introducing the Alkire–Foster method based on survey data collected from five provinces/autonomous regions. Results showed that the headcount ratio of child multidimensional poverty was 14.29%. On average, multidimensionally poor children were deprived in 37.62% of all the dimensions, and their adjusted headcount ratio (multidimensional poverty) index was 0.054. Health was the most deprived dimension, followed by the subsistence and participation dimensions. Disabled children, children influenced by HIV/AIDS, and ethnic minority children were severely deprived. This study not only adds to the current literature on child poverty in China, but also provides policy suggestions for future action plans.     

吕本中“活法”诗论针对性探微

吕本中所作《夏均父集序》,主张作诗用“活法”。他在南北宋之际一再强调这种理论的现实背景是什么？学界或以为是针对黄庭坚句法、字法体系及江西诗派末流之弊。据笔者考察,若说有现实针对性的话,极可能是当时受官方词科四六“典雅派”影响的诗坛,吕本中没有从江西诗派内部“造反”的任何可能。

我国农村双元养老模式探析

随着我国人口老龄化的日益严重,农村养老问题引起了人们更多的关注.由于目前我国农村的经济发展水平相对低,农民的思想观念及组织程度等多方面与城市存在着差距,这客观上决定了农村和城市养老模式的不同.通过对家庭养老和社会养老概念的区分及结合对我国农村经济、文化等方面的现实考察,文章认为双元养老模式是我国农村养老的最优选择,现阶段应着重提高家庭养老的保障能力,同时积极采取措施促使向社会养老的转化.     

限制兼任教师与民国大学学术职业发展

民国初期,政府通过教学工作量将大学教师职业划分为专任教师和兼任教师两种类型。当时,大学盛行聘请兼任教师及专任教师在外校兼课,兼任教师和专任教师之间的区别不明显。这种现象受到了海内外学者的批评,此后,中国的学界、大学和政府逐渐限制兼任教师:学界注重构筑官职和学术职业的界限,限制大学专任教师兼任官职|大学约束本校教师外出兼课|政府限制大学聘请过多的兼任教师。到民国后期,中国大学学术职业的专任程度逐步提高。这一历程反映了大学由注重教学绩效向关注学术质量的转变。
