对知识产权国际保护的反思——从公共健康角度

当前,知识产权保护的国际化,实际上就是发达国家知识产权制度的国际化.在全球不同背景下强制性地运用单一制度必然会出现不和谐的声音,全球性的公共健康危机凸显了这种冲突,引发舆论对知识产权国际保护合理性的探讨.知识产权与健康权都是社会承认的基本人权,其中任何一种在特定的背景中都有自身的价值,但并非所有的人权都是并列的.当全球有数以万计的人正在遭受公共健康威胁时,孰重孰轻的问题就不言而喻了,应当使公共健康与知识产权国际保护已经失衡的天平回归平衡.     

Continuity and change in work-life balance choices

This paper explores the ways in which the work-life balance choices made by heterosexual couples differ in different generations, how such choices are gendered, and the extent to which 'individualization' provides an adequate conceptualization of the effects of social change on heterosexual couples. It argues that processes of individualization need to be seen in the context of changing social institutions, and that it is the de-institutionalization of 'the family' and the life course that is leading to a de-gendering of work-life balance choices. The paper draws on findings from a restudy of the family and social change and a study of the gender dimensions of job insecurity both of which were carried out in the same geographical location. The studies provide evidence of generational change in work-life balance choices and increasing occupational differentiation between heterosexual partners. This leads to a situation where increasingly choices are made which blur gendered boundaries and which has been made possible by a process of de-institutionalization of the male breadwinner family. Our findings support the contention that processes of individualization are more apparent amongst younger than older generations and that, because of changes external to the family, there is more negotiation and pragmatism amongst younger generations about work-life choices.     

How Employed Mothers in Australia Find Time for Both Market Work and Childcare

Time use studies find that employed mothers reduce their parental childcare time by much less than an hour for every hour they spend in market work. This paper uses data from the Australian Bureau of Statistics Time Use Survey 1997 (4,059 randomly selected households) to investigate how employed mothers manage to avoid a one-for-one trade-off between work and childcare. It compares the time allocation of employed fathers, employed mothers and non-employed mothers and finds that parents use non-parental childcare to reschedule as well as to replace their own childcare, that employed mothers reschedule activities from weekdays to weekends or to earlier or later in the day, and spend less time than other mothers in housework, childfree leisure and personal care.

Veblen in Reverse: Evidence from the Multinational Time-Use Archive

This paper explores the historical change in the work-leisure balance using time-diary evidence. Much of the recent discussion of this balance in the developed world has focused on paid work alone. What follows takes a different approach, considering the balance of all work time (paid plus unpaid) against leisure time and observes a tendency over recent decades for leisure to decline relative to work in this broad sense. Much is changing, in employment, family and consumption terms over this period. One possibility is that the relative increase in work time reflects the reversal of the status/leisure gradient: the financially privileged classes, which once had more leisure than others, now have less. But the paper closes with the speculation that this increase in work time for both men and women may be indirectly connected with the phenomenon of the women’s “dual burden”, via an unconsidered but nevertheless important principle of fairness in the distribution of work within households.     

民主政治建设的共和维度

共和民主制是人类社会的一种政体，是中国近代杰出政治家的共识与选择。共和强调政府的公共性、公平性与中立性，主张在民主基础上公权制衡。共和的核心理念是“天下为公”。市场经济主体是多元的，从计划经济转向市场经济的过程应是政府自觉地培育多元主体的过程，多元之间不是敌对关系，解决的方式是由多元均衡达到社会和谐。公共权力体系应向代表性的阶层、群体或集团全方位敞开，从而达到多元共赢的目的。     

信息技术如何实现契约治理与关系治理的平衡——基于D公司供应链治理案例

运用纵向案例研究,通过过程模型来解析基于契约和关系二元治理平衡的形成路径,打开信息技术与契约和关系的二元治理平衡之间的"黑箱"。研究发现,促进长期跨组织协同的关键在于实现基于关系和契约的治理机制平衡;信息技术能够在跨组织治理过程中实现治理机制的动态叠加,在治理机制不断优化的过程中实现治理机制之间的平衡。这一研究进一步丰富了跨组织治理理论,对中国企业在互联网环境下的长期合作具有启发和指导意义。     

Reliability of global sensitivity indices

Uncertainty and sensitivity analysis is an essential ingredient of model development and applications. For many uncertainty and sensitivity analysis techniques, sensitivity indices are calculated based on a relatively large sample to measure the importance of parameters in their contributions to uncertainties in model outputs. To statistically compare their importance, it is necessary that uncertainty and sensitivity analysis techniques provide standard errors of estimated sensitivity indices. In this paper, a delta method is used to analytically approximate standard errors of estimated sensitivity indices for a popular sensitivity analysis method, the Fourier amplitude sensitivity test (FAST). Standard errors estimated based on the delta method were compared with those estimated based on 20 sample replicates. We found that the delta method can provide a good approximation for the standard errors of both first-order and higher-order sensitivity indices. Finally, based on the standard error approximation, we also proposed a method to determine a minimum sample size to achieve the desired estimation precision for a specified sensitivity index. The standard error estimation method presented in this paper can make the FAST analysis computationally much more efficient for complex models.
