美国对华贸易的政治经济学分析

美国对华贸易虽以保持稳定的经贸关系为基础，但迫于国际政治需要和国内的集团利益，还存在许多不确定性。因此，中国应当从宏观上对中美经贸关系拓展战略性思维，加强开展商务外交，构建和谐的国际经贸新秩序；从微观上，完善政府的商务职能，加强企业国际化能力，充分发挥行业协会的作用，多方面促使中美贸易朝正常化方向发展。     

Poverty and social trends in Russia

The article describes the socioeconomic situation of the Russian population and its dynamics in 1992. The analysis is based on series of regional sociological surveys led by the All-Russian Living Standards Research Center and on official Russian statistical data. The basic unit of analysis is the family, and hence family typology approbated both in research and in practical social work is introduced. Besides describing and discussing the growing poverty tendencies in contemporary Russia, the article also contains methodological recommendations for social policy bodies and social workers on the strategy of work in social maintenance and social support of the least secure population strata.     

A Unified Approach to the Characterization of Equivalence Classes of DAGs, Chain Graphs with no Flags and Chain Graphs

Abstract.  A Markov property associates a set of conditional independencies to a graph. Two alternative Markov properties are available for chain graphs (CGs), the Lauritzen–Wermuth–Frydenberg (LWF) and the Andersson–Madigan– Perlman (AMP) Markov properties, which are different in general but coincide for the subclass of CGs with no flags . Markov equivalence induces a partition of the class of CGs into equivalence classes and every equivalence class contains a, possibly empty, subclass of CGs with no flags itself containing a, possibly empty, subclass of directed acyclic graphs (DAGs). LWF-Markov equivalence classes of CGs can be naturally characterized by means of the so-called largest CGs , whereas a graphical characterization of equivalence classes of DAGs is provided by the essential graphs . In this paper, we show the existence of largest CGs with no flags that provide a natural characterization of equivalence classes of CGs of this kind, with respect to both the LWF- and the AMP-Markov properties. We propose a procedure for the construction of the largest CGs, the largest CGs with no flags and the essential graphs, thereby providing a unified approach to the problem. As by-products we obtain a characterization of graphs that are largest CGs with no flags and an alternative characterization of graphs which are largest CGs. Furthermore, a known characterization of the essential graphs is shown to be a special case of our more general framework. The three graphical characterizations have a common structure: they use two versions of a locally verifiable graphical rule. Moreover, in case of DAGs, an immediate comparison of three characterizing graphs is possible.

微观辨证整体化之浅议

对微观辨证整体化研究 ,认为目前一是应该对大量的前期研究工作进行总结 ,对异病同证者及同病异证者的宏观症状进行循证医学研究 ;对异病同证者及同病异证者的微观指标进行循证医学研究 ;最终寻求宏观整体指标与微观整体指标的结合 ,从而使微观辨证升华到微观层次上的整体化水平。二是进行基因组学与中医证候相关性研究 ,寻找与中医证候相关的基因组 ,从而实现中医证候研究的基因水平上的整体化。     

科学执政、民主执政中的依法执政基本途径

依法执政或依法行政,作为执政方式最为直接、最为具体的基本实践环节或途径,在相当范围内反映着科学执政、民主执政的实现程度。这取决于《行政许可法》不打折扣地坚决实施,政府的依法执政职能方式从重管制向重服务转变;职能范围从“全能”向“有限”回归;职能性质由“专断”走向真正“民主”;职能习惯从主观随意转向严格的法治。     

以人为本 依法行使高校管理权

一、当前高校学生管理工作面临的形势我国高等学校的学生管理制度建设经历了一个曲折的发展过程。建国初期至60年代初,是我国高校学生管理制度的初创时期,学生管理制度的建设,主要侧重在对学生的学籍管理。“文革”时期,我国高校学生管理制度遭到严重破坏。1977年恢复高考制度,
