Mathematical models for academic webs: Linear relationship or non-linear power law?

Previous studies of academic web interlinking have tended to hypothesise that the relationship between the research of a university and links to or from its web site should follow a linear trend, yet the typical distribution of web data, in general, seems to be a non-linear power law. This paper assesses whether a linear trend or a power law is the most appropriate method with which to model the relationship between research and web site size or outlinks. Following linear regression, analysis of the confidence intervals for the logarithmic graphs, and analysis of the outliers, the results suggest that a linear trend is more appropriate than a non-linear power law.     

Environmental jolts, institutional change, and the creation of entrepreneurial opportunity in the US electric power industry

The relationship between institutional change and entrepreneurship is poorly understood. We build the theory in this area by tracing institutional change in the US electric power industry over a 40-year period. Our analysis shows that environmental jolts mobilize actors to reformulate institutions, resulting in increased entrepreneurial opportunity. When the institutional environment is stable, we find that incumbent organizational forms and embedded logics present formidable obstacles to entrepreneurial activity. Environmental jolts, however, catalyze search processes and motivate the evaluation of current institutional logics. Specifically, in the case of the electric power industry, environments of abundance and regulation resulted in homogeneity of organizational structures and strategies, and few entrepreneurial opportunities. Environments marked by scarcity and crisis, however, witnessed heavy scrutiny of existing institutional arrangements that eroded their taken-for-grantedness and symbolic value, resulting in opportunities for entrepreneurial action.

张衡的政治思想

张衡不仅是一位著名的科学家和文学家，而且是一位卓越的政治家。他在科学研究、文学创作和为官从政的过程中，都能公正廉洁，勤职尽责，忧国忧民，有很强的责任感。他提出了不少独到的政治见解：一是惩贪倡廉，尊君爱民；二是选贤使能以“教化为本”；三是提倡科学执政，破除谶纬迷信。

农民战争的命运和农民的局限性——太平天国及义和团运动失败的教训

太平天国农民革命和义和团反帝爱国运动,是中国近代农民运动的两次高潮,意义重大,影响深远,但最终还是失败了。失败的原因是多方面的,研究发现,太平天国失败的根本原因,在于农民小生产者阶级的局限性使革命队伍日益受到封建主义的侵袭,滋长了保守、迷信、享乐、皇权等封建思想意识。其表现为封建皇权主义思想严重,家天下、迷于权势、争权夺利和生活腐化,以致内部流血内讧,导致太平天国运动的最后失败。历史告诉我们,旧式农民战争推翻不了封建制度。同样,义和团也无法摆脱旧式农民战争的归宿,他们英勇反抗,拼死奋斗,仍不能赶走入侵的帝国主义。义和团失败的根本原因在于其笼统的和极端排外主义及封建蒙昧主义。笼统排外又是封建蒙昧主义的突出表现,不符合中国人民的根本利益,导致了行动上的盲目性和落后性,其结果是孤立了自己,壮大了敌人,使反帝斗争陷于歧途,悲壮失败。太平天国和义和团运动失败的历史表明,封建皇权主义和笼统的排外主义,是旧民主主义革命时期农民革命和农民战争的两个致命弱点,在半封建半殖民地的中国,农民不能独立完成反帝反封建的革命任务,自发的农民思想不能拯救中华。     

Complex Dynamics Caused by Torus Bifurcation in Power Systems

Torus bifurcation is a relatively complicated bifurcation caused by a pair of complex conjugate Floquet multipliers coming out of unit circle on the Poincare section. A three-bus system is employed to reveal the relationship between torus bifurcation and some complex dynamics. Based on theoretical analysis and simulation studies, it is found that torus bifurcation is a typical route to chaos in power system. Some complex dynamics usually occur after a torus bifurcation, such as self-organization, deep bifurcations, exquisite structure, coexistence of chaos and divergence. It is also found that chaos has close relationship with various instability scenarios of power systems. Studies of this paper are helpful to understand the mechanism of torus bifurcation in power system and relationship of chaos and power system instabilities.

中国共产党与西方执政党执政方式比较及启示

中国共产党同西方发达资本主义国家的执政党在性质上是不同的。但同为政党,在执政方式上,值得比较与研究。通过差异性的比较和规律性的总结,可以从中得到若干启示:增强执政的合法性,规范党政关系,强化对权力的监督与制约,这些对改革和完善我党执政方式都有参考意义。
