Rényi entropy of m-generalized order statistics

Abstract

Characterizing relations via Rényi entropy of m-generalized order statistics are considered along with examples and related stochastic orderings. Previous results for common order statistics are included.     

Examples of the use of an equivalence theorem in constructing optimum experimental designs for random-effects nonlinear regression models

The problem considered is that of finding an optimum measurement schedule to estimate population parameters in a nonlinear model when the patient effects are random. The paper presents examples of the use of sensitivity functions, derived from the General Equivalence Theorem for D-optimality, in the construction of optimum population designs for such schedules. With independent observations, the theorem applies to the potential inclusion of a single observation. However, in population designs the observations are correlated and the theorem applies to the inclusion of an additional measurement schedule. In one example, three groups of patients of differing size are subject to distinct schedules. Numerical, as opposed to analytical, calculation of the sensitivity function is advocated. The required covariances of the observations are found by simulation.     

Modeling cooperation among self-interested agents: a critique

This paper reviews recent attempts to model cooperation in groups of self-interested unrelated individuals. It concludes that no empirically plausible model has been developed, and the economist's quest for an explanation of human prosociality in terms of self-interested agents has not been successful. We show that the equilibrium criteria employed in standard game-theoretic models have no attractive dynamic properties, and the mechanisms deployed in these models are not generally seen in empirical examples of cooperative groups. We also show that these models are not robust to plausible rates of signaling error and mutation. We present an alternative, involving strongly reciprocal agents, that satisfies all the requirements for a dynamically stable model of cooperation.     

采用二阶特征窗的语音盲分离方法

利用语音信号的短时平稳特性,提出了一种二阶特征窗语音盲分离方法。该方法采用新的联合差分相关矩阵白化算法去除有色噪声影响;用长度等于语音信号基音周期的等距特征窗连续分割预白化观测数据,在每个加窗的数据帧计算不同的时滞协方差矩阵。利用联合近似对角化时滞协方差矩阵集合得到旋转参数,最终达到语音信号的盲分离。该方法消除了有色噪声的影响,只需用到二阶信息就能很好地分离语音信号。仿真实验验证了该方法的有效性。     

分权制衡理论的发展脉络及其理论内核

分权制衡是西方政治学的重要理论，是“三权分立”思想的基础。分权制衡的思想在基督教义中就有体现，柏拉图、亚里士多德等人提出的古代混合政体理论也提出了分权思想，并且出现了三权分立的雏形，而中世纪的最大贡献则是立法权从王权和教权中分立出来。分权制衡思想的成熟分为两个阶段：即侧重于理论的启蒙思想发展阶段和在美国建国实践中完善的阶段。分权制衡理论基于对人性的一种悲观评价，是对人民主权理论所带来的“多数人的暴政”的一种限制和预防，是法治对人治的驱逐。     

美国陪审制度与权力分立制衡思想

美国是典型的三权分立国家,权力分立与制衡思想在美国是多角度、多层次立体式展开的.陪审制度作为美国特色的制度,体现了公民权利与国家权力、民众与法官、非法律专业人士与法律职业人士之间的分权与制衡.

但丁的声誉与但丁政治理念在欧洲的命运

梳理了14世纪至19世纪后半叶但丁政治理念在欧洲的境遇及其与但丁诗人声誉的联系。除“俗语问题”外,但丁在《帝制论》中提出的政教分离的政治理念是他最初遭到反对的最重要原因,虽然在15世纪~16世纪欧洲文艺复兴与宗教改革运动中但丁的理论曾引起人们的注意,但17世纪~18世纪人们对但丁的低俗化误读使他的诗人声誉仍然下滑。但丁的声誉随着意大利民族意识的觉醒与呼唤民族解放的欧洲浪漫主义运动而不断走向辉煌,这一转折点就是意大利历史哲学家维柯。
