二阶段供应链中提前期压缩的影响与协调

提前期是衡量业务过程绩效一个重要的因素,基于时间竞争的供应链管理战略核心就在于提前期的压缩,提前期压缩是形成供应链战略优势的有力来源.在市场需求预测精度随提前期变化的假设下,采用逻辑证明和数值分析的方法,研究由供应商-零售商构成的两阶段供应链中提前期压缩对供应链及其成员收益的影响以及如何实现供应链的渠道协调.研究结果表明:当供应链的服务水平小于0.5时,提前期的压缩可以获得供应链成员收益的Pareto改进;当供应链的服务水平大于等于0.5,引入线性转移支付补偿机制,可以实现供应链的渠道协调,获得供应链成员收益的Pareto改进.

Analysis of the Bovine Spongiform Encephalopathy Maternal Cohort Study: the Discordant Case–Control Pairs

The progeny of the affected and non-affected dams in the bovine spongiform encephalopathy (BSE) cohort study were paired in terms of their farm of origin and approximate date of birth. This paper presents an exact logistic regression analysis that avoids modelling the differences between the pairs and so analyses only the discordant pairs. There is some evidence that the pairs in which the affected animal was born to the affected dam tend to be those in which the onset of BSE in the affected dam preceded or occurred soon after the calving. This suggests some occurrence of maternal transmission.     

Is the Way Young People Drive a Reflection of the Way Their Parents Drive? An Econometric Study of the Relation Between Parental Risk and Their Children's Risk

This article aims to investigate parental influence on high-risk behavior by young people. Although research on the topic of perception of risk demonstrates that it is socially constructed, the role of the family in this construction has rarely been studied. Using a French national survey of more than 1,200 young drivers between the ages of 18 and 25, and their parents, we attempt to understand the transmission of risk within families. Our econometric study shows that parents influence both the practices and representations of their children. When parental norms and values are transmitted, they are by no means accepted in a wholly passive way. Indeed, the parental model is in competition with other models that originate from both inside the family (brothers and sisters) and outside it (instructors). Furthermore, parental influence decreases over time as young people become more experienced drivers and construct their own identity with regard to risk.     

嘉道之际福建霍乱的传入及其流行

清嘉庆末年至道光初年间，古典型霍乱在中国广泛流行，福建也是此次霍乱流行的一个重灾区。通过考察清朝福建的海外贸易，并分析嘉道年间福建霍乱流行的时间和区域，霍乱病极有可能是直接由东南亚国家经过海上贸易传入造成的，而不是通过广东传入福建。

天主教在土家族地区的传播探析——以湖北利川为例

天主教作为外来宗教，能在利川占有一席之地并发展到一定规模，是具有历史渊源的。天主教在湖北利川传播的历史状况、传教方式及其演变过程，不仅有其独特原因和特点，还从积极和消极两方面，对当地土家族人民的生活及其宗教信仰产生了广泛影响。     

后工业时代标志系统的设计

随着社会的发展,尤其是后工业时代的来临,社会的服务性因素被高度重视,大众的地位从被动提升到了主动。由此产生的现代标志系统,把关注大众的心理感受作为一个至关重要的一个命题。一套良好的标志系统应当包含大量经过筛选的优质信息。首先,设计师不可忽视标志系统作为传达讯息的一种符号体系所拥有的共同特点：可认知性、普遍性和稳定性;其次,设计师必须了解,为了准确地传达出信息,标志系统设计必须使用精炼的抽象概念对人的视觉经验产生影响。
