AN ALGORITHM FOR THE CONSTRUCTION OF OPTIMAL OR NEAR-OPTIMAL CHANGE-OVER DESIGNS

This paper presents an algorithm for the construction of optimal or near optimal change-over designs for arbitrary numbers of treatments, periods and units. Previous research on optimality has been either theoretical or has resulted in limited tabulations of small optimal designs. The algorithm consists of a number of steps:first find an optimal direct treatment effects design, ignoring residual effects, and then optimise this class of designs with respect to residual effects. Poor designs are avoided by judicious application of the (M, S)-optimality criterion, and modifications of it, to appropriate matrices. The performance of the algorithm is illustrated by examples.

Generalized partially linear varying-coefficient models

Generalized varying-coefficient models are useful extensions of generalized linear models. They arise naturally when investigating how regression coefficients change over different groups characterized by certain covariates such as age. In this paper, we extend these models to generalized partially linear varying-coefficient models, in which some coefficients are constants and the others are functions of certain covariates. Procedures for estimating the linear and non-parametric parts are developed and their associated statistical properties are studied. The methods proposed are illustrated using some simulations and real data analysis.

中东油气与中国石油发展的战略思考

在当前国际环境下,中国的石油安全战略应是开放和外向型的,其核心思想是“保内争外”,即中国政府应进一步加强对中国石油企业参与国际能源合作的宏观指导和支持;中国石油企业应加强国内油气资源的可持续开发和利用,坚持开展国际能源合作,直面国际博弈。中东国家油气资源丰富,且与中国关系友好,应是中国石油企业对外开展能源合作的首选地区。

Communicating Global Activism

Many observers doubt the capacity of digital media to change the political game. The rise of a transnational activism that is aimed beyond states and directly at corporations, trade and development regimes offers a fruitful area for understanding how communication practices can help create a new politics. The Internet is implicated in the new global activism far beyond merely reducing the costs of communication, or transcending the geographical and temporal barriers associated with other communication media. Various uses of the Internet and digital media facilitate the loosely structured networks, the weak identity ties, and the patterns of issue and demonstration organizing that define a new global protest politics. Analysis of various cases shows how digital network configurations can facilitate: permanent campaigns; the growth of broad networks despite relatively weak social identity and ideology ties; transformation of individual member organizations and whole networks; and the capacity to communicate messages from desktops to television screens. The same qualities that make these communication-based politics durable also make them vulnerable to problems of control, decision-making and collective identity.

阿尔都塞意识形态理论研究述评

阿尔都塞的意识形态理论独树一帜，曾产生过巨大影响。近年来，学术界对其思想的研究日益聚焦在这一方面，并出现一大批理论成果。目前，国内对这一思想的研究主要集中在对其理论渊源、内容、贡献和缺陷的认识等方面。阿尔都塞在诸多方面时马克思主义的意识形态理论都进行了丰富和发展，甚至触及到经济基础和上层建筑相互作用的机制问题，但其捍卫马克思主义的“初衰”并未真正如愿以偿。
