和而不同与和谐语言文化的建设

和谐是多样性的统一.作为一个民族多元、文化多元的国家,中国应从传统的"和而不同"思想出发,处理好普通话与方言、汉语与外来语、共同语与民族语的关系,创造和谐的语言文化.

西方发达国家政府舆论宣传管理措施述论

西方发达国家政府一贯重视舆论宣传,在依靠硬性管理措施如行政力量、法律法规和强制措施管理宣传活动的同时,也重视利用软性管理措施,如政府新闻发言人制度、政治人物的影响、传媒公司控制以及依靠大型财团垄断传媒等手段,增强对舆论宣传的影响力,在舆论宣传管理措施上呈现出手法多样又灵活多变的特点.     

Geometric rounding: a dependent randomized rounding scheme

We develop a new dependent randomized rounding method for approximation of a number of optimization problems with integral assignment constraints. The core of the method is a simple, intuitive, and computationally efficient geometric rounding that simultaneously rounds multiple points in a multi-dimensional simplex to its vertices. Using this method we obtain in a systematic way known as well as new results for the hub location, metric labeling, winner determination and consistent labeling problems. A comprehensive comparison to the dependent randomized rounding method developed by Kleinberg and Tardos (J. ACM 49(5):616–639, 2002) and its variants is also conducted. Overall, our geometric rounding provides a simple and effective alternative for rounding various integer optimization problems.     

The role,power and influence of company chairs

This paper develops an analytical framework to depict the heterogeneity that characterises the role of board chair and demonstrate the potential variability in how chairs operate boards and exercise power and influence on strategy, control and resource related tasks at board level. Theories of power and influence, as applied to top management teams and boards of directors, are explicated within the context of contemporary governance practices that are establishing the role of the board chair as distinct to that of the chief executive officer. Specifically, the paper maps sources of power and varying contemporary chair practices, including chair nomenclature (i.e. executive vs. non-executive chairs), chair origin (insider vs. outsider) and chair time (full-time vs. part-time). A number of theoretical chair-power models emerge from this analysis and are subject to empirical analysis using data collected from 160 chairs of 500 FTSE-listed companies. Theoretically and empirically, the paper complements structural approaches to studying boards with attention to behaviour on boards. By linking board structure, board process and the exercise of influence, the study reveals both differences amongst chairs in how they run the board, but also that chairs’ differ in the influence they exert on board-related tasks. Full-time executive chairs exert their greatest influence in strategy and resource dependence tasks whereas part-time, non-executive chairs seem to exert more influence over monitoring and control tasks.     

半依附:1949-1956年中国政治发展的重要特征

1949-1956年中国的政治发展理念、外交政策和实践、政治制度和政治发展过程等方面具有明显的半依附特征.新中国"主动的半依附"所期望的国家利益与"被动的半依附"所付出的代价并存.相应地,半依附政治发展的后果也是悲喜各半:尽管这一政治发展模式有利于新中国政权的巩固,但也使其政治发展受到苏联的影响和制约,成为自主政治发展的障碍,甚至某些适合中国国情的制度创新也逐渐被苏联模式侵蚀.半依附政治发展的重要教训在于弱国必须谨慎处理与实力悬殊的强国之间的结盟关系问题,并尽早做好同盟破裂的应对措施.     

"言之有据"与"言之成理":史学叙事与文学写作的同与异

历史叙事首先得"言之有据",然后还要"言之成理".如果我们用这八个字去衡量、比较历史叙事与文学写作的异同,起先(言之有据)的差异是明显的,稍后(言之成理)便逐渐模糊了,与其说是"殊途同归",毋宁说是"异曲同工".     

基于有效预测区域的模糊数据关联

多目标多传感器跟踪系统由数据关联和目标状态估计两部分组成,数据关联是多目标跟踪系统研究的核心。数据关联和目标状态估计两部分既有一定的独立性又有密切的联系,而将两部分合理地结合对提高跟踪系统的性能是重要的。该文以跟踪目标的有效预测区域为依据,利用基于Mahalanobis距离的模糊均值聚类方法解决数据关联问题,在一定程度上将数据关联和目标状态估计两个不同的过程相结合,仿真计算说明了其有效性。

论胡瑗的天人合一与他的自然观

胡瑗继承了中国传统道家和儒家“天人合一”的思想，强调“天”与“人”的互为感应，主张继天地自然之功，使人的一切言行都能顺应“自然”，与“天”相合。胡瑗还将内圣之学与宇宙大道联系起来，认为治理国家也要符合天地之道，按自然发展规律办事。此外还要求根据事物发展变化之规律，树立变易观念，顺时顺势及时调整自己的决策与行为。
