进京保姆：一种特殊的女性劳动力转移模式——基于L村的个案分析

劳动力转移流向和从业领域的高度一致,使“进京保姆”成为L村女性劳动力转移的一种特殊模式。这种模式既打破了以往“男主外、女主内”的性别分工,也强化了市场化分工在当前劳动力转移中的主导作用。L村女性劳动力转移经历了由生存理性到经济理性和社会理性的转变。由理性选择促成的“保姆经济”成为L村经济发展和观念更新的重要动因。从长远看,L村女性劳动力集中进京已经造成村庄内婚姻家庭解体、儿童老人问题突出等诸多问题。这种“发展的悖论”应是后续研究和决策所必须面对和解决的问题。     

A Transnational Flow of the Art of Tea: The Paradox of Cultural Authenticity in Taiwan

Being regarded as representing authentic Chinese cultural tradition in the eyes of many mainland Chinese, the Taiwanese practice of the art of tea, however, is displayed as an adapted authenticity that integrates multiple sources, including Chinese cultural legacy, Japanese art influences and constant innovations by Taiwanese actors. By conditionally selecting whether to side with Japanese or Chinese culture, a Taiwanese cultural identity through the art of tea is manifested as quests for liberal changes, leisure lifestyle, anti-showy representation and a paradox over commodified practices. This article traces the historical and ongoing transnational cultural flow among China, Taiwan and Japan in the art of tea, and focuses on exploring Taiwanese cultural reconstruction through the development of the art of tea. The author argues that the trajectory of the art of tea intrinsically reflects the paradox of cultural authenticity in Taiwan.     

论企业集群的优势创造与保持:制度的视角

全球化条件下的“位置悖论”促进了企业集群的理论研究与政策应用。在本文中,笔者解释了“位置悖论”,在此基础上提出并分析了“集群悖论”。制度是企业集群竞争优势的基础,集群治理是企业集群长期竞争优势的制度基础。     

道德悖论与道德选择

道德悖论是悖论的一个特殊领域,是道德现象世界中一种特殊的矛盾,是一种出现在行为选择的结果、具有善恶绝对对立和对抗性质的自相矛盾。道德悖论是由道德价值实现的特殊性、人的道德价值判断能力的不足和事实判断与价值判断的分离而造成的。可以从道德选择的角度,通过改造德性主义的道德传统,提高道德选择能力,用"道德智慧"消解道德悖论,以推动伦理学理论更趋于科学性。     

中国民营高科技企业产权制度变迁研究

由于“公有民营高科技企业”和“民办民营高科技企业”在产权制度演变过程中具有不同的特点 ,因此在向股份制变迁过程中 ,前者应选择政府主导的强制性制度变迁 ,后者应选择诱致性制度变迁 ,并通过后者带动前者以突破公有民营高科技企业产权制度变迁中存在的“诺思悖论”。在两类民营高科技企业的产权制度变迁中存在不同的难点 ,针对这些难点 ,本文提出了具体的对策和建议     

Comparative Ignorance and the Ellsberg Paradox

We investigate the evaluation of known (where probability is known) and unknown (where probability is unknown) bets in comparative and non-comparative contexts. A series of experiments support the finding that ambiguity avoidance persists in both comparative and non-comparative conditions. The price difference between known and unknown bets is, however, larger in a comparative evaluation than in separate evaluation. Our results are consistent with Fox and Tversky's (1995) Comparative Ignorance Hypothesis, but we find that the strong result obtained by Fox and Tversky is more fragile and the complete disappearance of ambiguity aversion in non-comparative condition may not be as robust as Fox and Tversky had supposed.     

论"语言转向"的发生

“语言转向”发源于20世纪初的逻辑分析学派,它的发生基于自然科学的发展,尤其是数学史上的罗素悖论与物理学史上相对论的提出;而古希腊哲学、近代哲学都与自然科学的发展密切相关,因而“语言转向”在逻辑上是对哲学传统的继续。在方法上它一反传统的归纳演绎代之以逻辑分析;在思路上抛弃了近代哲学的理性标准而关注问题的根本———语言,因而它又是对哲学传统的反叛。但纯科学主义立场的缺陷也决定了它必然走向新的发展。     

人力资本产权残缺:诠释浙江-陕西经济增长之谜

透过“浙江—陕西经济增长之谜”的研究发现,转型经济中的人力资本产权残缺已成为影响地区经济发展的重要因素;其残缺程度越大,则人力资本对经济发展的推动作用就越被弱化。     

Communication of ambiguous risk information

This paper reports on the responses of 646 individuals to environmental risk information involving different forms of risk ambiguity. Recipients of more than one set of risk information do not simply average the risk levels provided. Rather, a variety of aspects of the nature of the risks that are communicated influence their probabilistic beliefs. Individuals' perceptions of the risk levels to which they are exposed are likely to be greater: (i) for more ambiguous risks, (ii) for risks for which the unfavorable risk evidence is presented last even when there is no temporal order, (iii) for risks for which the most unfavorable risk studies have been performed most recently, and (iv) for risks where there is asymmetry in the risk ambiguity that imposes substantial potential downside risks. Although these effects are modest for the median individual, the potential for extreme responses that reflect only the most adverse or the most favorable piece of information provided is quite prevalent. These findings are of interest more generally in that they indicate how individuals form their risk perceptions in the presence of risk ambiguity.The authors would like to thank the U.S. Environmental Protection Agency for support of this work under Cooperative Agreements Number CR-815445-01-2 and Number CR-814388-02-1. Dr. Alan Carlin and Dr. Ann Fisher provided valuable guidance in the design of the project, and Dr. Doyle Graham and Dr. Douglas Anthony offered generous assistance in communicating the medical consequences of nerve disease to subjects. Jon LaScala assisted superbly in the administration and analysis of the survey, and Patricia Born provided additional computer programming assistance.     

Time,bounded utility,and the St. Petersburg paradox

The assumption of bounded utility function resolves the St. Petersburg paradox. The justification for such a bound is provided by Brito, who argues that limited time will bound the utility function. However, a reformulated St. Petersburg game, which is played for both money and time, effectively circumvents Brito's justification for a bound. Hence, no convincing justification for bounding the utility function yet exists.
