An evolutionary algorithm for A-optimal incomplete block designs

Evolutionary algorithms are heuristic stochastic search and optimization techniques with principles taken from natural genetics. They are procedures mimicking the evolution process of an initial population through genetic transformations. This paper is concerned with the problem of finding A-optimal incomplete block designs for multiple treatment comparisons represented by a matrix of contrasts. An evolutionary algorithm for searching optimal, or nearly optimal, incomplete block designs is described in detail. Various examples regarding the application of the algorithm to some well-known problems illustrate the good performance of the algorithm

从结构到意义：戈德曼的发生学结构主义

吕西安·戈德曼是“西方马克思主义”研究中一座有待深入发掘的富矿。他基于发生学结构主义的社会学批评理论，以六大重要范畴为核心，提出作品与现实在内在结构上具有“同源性”的理论。这样就把作品的本文结构与意识形态及社会本质联系起来，实现了审美形式与历史意义的链接。戈德曼的发生学结构主义不仅本身构成了自足的理论模型，而且能够对比较文学、叙事学等研究方向提供理论支持和有效借鉴。     

Differentiating Contemporary Racial Prejudice from Old-Fashioned Racial Prejudice

The present study addresses the distinction between contemporary and old-fashioned prejudice using survey data from a national sample (n = 600) of self-identified whites living in the United States and interviewed by telephone in 2001. First, we examine associations among indicators of contemporary and old-fashioned prejudice. Consistent with the literature, contemporary and old-fashioned prejudice indicators represent two distinct but correlated common factors. Second, we examine whether belief in genetic race differences uniformly predicts both types of prejudice. As might be expected, belief in genetic race differences predicts old-fashioned prejudice but contrary to recent theorizing, it also predicts contemporary prejudice.

转基因作物基因资源的知识产权保护进路研究

知识产权是知识财产私有的权利形式,是一种基于个体的权利生成,面对权利客体的多样性创新,特别是转基因作物基因资源集合了自然公共属性和个体价值属性,对知识产权保护进路形成突破。以农民权为基础和框架构建的基因资源权应注入社区发展权的公共性理念,通过社区共享性制度系统促进转基因作物基因资源与知识产权保护的双向度互动式发展进路。

A genetic algorithm approach to developing the multi-echelon reverse logistics network for product returns

Traditionally, product returns have been viewed as an unavoidable cost of doing business, forfeiting any chance of cost savings. As cost pressures continue to mount in this era of economic downturns, a growing number of firms have begun to explore the possibility of managing product returns in a more cost-efficient manner. However, few studies have addressed the problem of determining the number and location of centralized return centers (i.e., reverse consolidation points) where returned products from retailers or end-customers were collected, sorted, and consolidated into a large shipment destined for manufacturers’ or distributors’ repair facilities. To fill the void in such a line of research, this paper proposes a nonlinear mixed-integer programming model and a genetic algorithm that can solve the reverse logistics problem involving product returns. The usefulness of the proposed model and algorithm was validated by its application to an illustrative example dealing with products returned from online sales.     

哈贝马斯基因伦理思想初探

哈贝马斯是当代著名的思想家,科学技术是他考察的一个重要话题。他的新作《人性的未来》一书,集中表达了他对基因干预、基因改善、自由优生与人性关系的看法。在这本书中,哈贝马斯以当前基因技术的发展为基础,考察了基因技术与人的道德之间出现的矛盾和冲突。在反思这些矛盾和冲突的时候,他从人类学的广阔视野出发,认为只有将人的生命置于主体间性中,才能避免在基因技术发展中对其他生命的控制和操纵。
