毛泽东对中共党史功能和作用的运用和发挥

毛泽东不仅对党史学科的形成和发展做出了重要贡献,并提出了一系列党史研究的原则和方法。尤其是在长期的领导工作中,十分注重发挥中共党史的功能和作用,如他注意以党史解说党的政策、以党史教育干部群众、以党史指导党的建设、以党史阐明哲学理论、以党史联络各方朋友、以党史鉴正党的决误、以党史弘扬传统文化。毛泽东对中共党史功能和作用的充分运用和发挥,为我们充分重视和正确估价中共党史的理论价值和学科定位提供了有益的思考。     

Doubly periodic non-homogeneous Poisson models for hurricane data

Non-homogeneous Poisson processes with periodic claim intensity rate have been proposed as claim counts in risk theory. Here a doubly periodic Poisson model with short- and long-term trends is studied. Beta-type intensity functions are presented as illustrations. The likelihood function and the maximum likelihood estimates of the model parameters are derived.Doubly periodic Poisson models are appropriate when the seasonality does not repeat exactly the same short-term pattern every year, but has a peak intensity that varies over a longer period. This reflects periodic environments like those forming hurricanes, in alternating El Niño/La Niña years. An application of the model to the data set of Atlantic hurricanes affecting the United States (1899–2000) is discussed in detail.

Improved minimax estimation of a normal precision matrix

Let S_{p × p} have a Wishart distribution with parameter matrix Σ and n degrees of freedom. We consider here the problem of estimating the precision matrix Σ^?1 under the loss functions L₁(σ) tr (σ) - log |σ| and L₂(σ) = tr (σ). James-Stein-type estimators have been derived for an arbitrary p. We also obtain an orthogonal invariant and a diagonal invariant minimax estimator under both loss functions. A Monte-Carlo simulation study indicates that the risk improvement of the orthogonal invariant estimators over the James-Stein type estimators, the Haff (1979) estimator, and the “testimator” given by Sinha and Ghosh (1987) is substantial.     

Identifiability of Finite Mixtures of Elliptical Distributions

Abstract.  We present general results on the identifiability of finite mixtures of elliptical distributions under conditions on the characteristic generators or density generators. Examples include the multivariate t -distribution, symmetric stable laws, exponential power and Kotz distributions. In each case, the shape parameter is allowed to vary in the mixture, in addition to the location vector and the scatter matrix. Furthermore, we discuss the identifiability of finite mixtures of elliptical densities with generators that correspond to scale mixtures of normal distributions.     

On the Distance Between Cumulative Sum Diagram and Its Greatest Convex Minorant for Unequally Spaced Design Points

Abstract.  The supremum difference between the cumulative sum diagram, and its greatest convex minorant (GCM), in case of non-parametric isotonic regression is considered. When the regression function is strictly increasing, and the design points are unequally spaced, but approximate a positive density in even a slow rate ( n ^−1/3), then the difference is shown to shrink in a very rapid (close to n ^−2/3) rate. The result is analogous to the corresponding result in case of a monotone density estimation established by Kiefer and Wolfowitz, but uses entirely different representation. The limit distribution of the GCM as a process on the unit interval is obtained when the design variables are i.i.d. with a positive density. Finally, a pointwise asymptotic normality result is proved for the smooth monotone estimator, obtained by the convolution of a kernel with the classical monotone estimator.

从词类范畴化理论看“副词＋名词”结构

不少学者对汉语中所谓的“副词＋名词”结构从各方面进行了研究，但是无一质疑该结构中心词的词类判断。对刘正光等人提出的观点提出质疑，认为：汉语词类的判断不能依赖于直觉或语义，而应在使用大型汉语语料库的基础上，依据词的语法功能来确定；词类范畴化是动态的过程，包括去范畴化和再范畴化，再范畴化是去范畴化的最终结果；对于“副词＋名词”结构中发生的词类去范畴化，语法转喻是其内在运作机制。     

论我国民主党派监督职能的发挥

民主监督是我国民主党派的主要职能之一 ,但是目前这种职能并没有得到充分的发挥。要充分发挥这种职能 ,其前提是必须深刻认识民主党派实行监督职能的必要性和可能性 ,其关键是要建立一种能使监督者主动实行监督 ,被监督者不得不接受监督的机制     

Density estimation for samples satisfying a certain absolute regularity condition

Let {ξ_i} be an absolutely regular sequence of identically distributed random variables having common density function f(x). Let H_k(x,y) (k=1, 2,…) be a sequence of Borel-measurable functions and f_n(x)=n^?1(H_n(x,ξ₁)+…+H_n(x,ξ_n)) the empirical density function. In this paper, the asymptotic property of the probability P(sup_x|f_n(x)?f(x)|>ε) (n→∞) is studied.
