普通高等教育可持续发展框架——特区建设的设想

在解读地方政府热衷于“大学城”建设的原因以及普通高等教育发展中的体制性障碍———“政府失灵”的基础上,提出了搭建普通高等教育特区的设想,并建议将辽宁省大连市作为试点地区,通过机制创新,开辟全新的普通高等教育可持续发展之路。     

毛泽东率先创建农村革命根据地原因再认识

毛泽东之所以能够领导秋收起义部队率先创建第一个农村革命根据地 ,是由于他对处于低潮的革命形势估计较客观 ,特别注重正规革命军队的保存、建设和发展 ,并预先谋划了起义万一失败的退路———上山

Estimating the First- and Second-Order Parameters of a Heavy-Tailed Distribution

This paper suggests censored maximum likelihood estimators for the first‐ and second‐order parameters of a heavy‐tailed distribution by incorporating the second‐order regular variation into the censored likelihood function. This approach is different from the bias‐reduced maximum likelihood method proposed by Feuerverger and Hall in 1999. The paper derives the joint asymptotic limit for the first‐ and second‐order parameters under a weaker assumption. The paper also demonstrates through a simulation study that the suggested estimator for the first‐order parameter is better than the estimator proposed by Feuerverger and Hall although these two estimators have the same asymptotic variances.     

正规集的若干性质

正规集是对许多语言理论起核心作用的一类语言，研究正规集的性质有助于有限态文法的文法推断和句法分析的研究以及正规集的自动识别。在文献［１］的基础上对正规集的一些重要性质进行了详细讨论，完善了正规集的理论。     

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.     

THE CONVERGENCE RATE OF SEQUENTIAL FIXED-WIDTH CONFIDENCE INTERVALS FOR REGULAR FUNCTIONALS

Let X₁X₂,.be i.i.d. random variables and let U_n= (n r)^-1S?^(n,r) h (X_i1,., X_ir,) be a U-statistic with EU_n= v, v unknown. Assume that g(X₁) =E[h(X₁,.,X_r) - v |X₁]has a strictly positive variance s?². Further, let a be such that φ(a) - φ(-a) =α for fixed α, 0 < α < 1, where φ is the standard normal d.f., and let S²_n be the Jackknife estimator of n Var U_n. Consider the stopping times N(d)= min {n: S²_n: + n^-1≤²a^-2},d > 0, and a confidence interval for v of length 2d,of the form I_n,d= [U_n,-d, Un + d]. We assume that Var U_n is unknown, and hence, no fixed sample size method is available for finding a confidence interval for v of prescribed width 2d and prescribed coverage probability α Turning to a sequential procedure, let I_N(d),d be a sequence of sequential confidence intervals for v. The asymptotic consistency of this procedure, i.e. lim_{d → 0}P(v ∈ I_N(d),d)=α follows from Sproule (1969). In this paper, the rate at which |P(v ∈ I_N(d),d) converges to α is investigated. We obtain that |P(v ∈ I_N(d),d) - α| = 0 (d^{1/2-(1+k)/2(1+m)}), d → 0, where K = max {0,4 - m}, under the condition that E|h(X₁, X_r)|^m < ∞m > 2. This improves and extends recent results of Ghosh & DasGupta (1980) and Mukhopadhyay (1981).     

A GALTON-WATSON BRANCHING PROCESS IN VARYING ENVIRONMENTS WITH ESSENTIALLY CONSTANT OFFSPRING MEANS AND TWO RATES OF GROWTH1

A Galton-Watson process in varying environments (Z_n), with essentially constant offspring means, i.e. E(Z_n)/mⁿ→α∈(0, ∞), and exactly two rates of growth is constructed. The underlying sample space Ω can be decomposed into parts A and B such that (Z_n)_n grows like 2ⁿon A and like mⁿon B (m > 4).     

以网络为平台的大学生组织生活质量模式探析

目前,大学生组织生活存在内容不够丰富、形式缺乏吸引力,成员沟通交流不足、缺乏民主互动氛围,组织生活缺少针对性和系统性等问题。借助网络平台可以便捷地运用党员教育资源,有效扩大党员教育的辐射度与受益面,从而增强组织生活的吸引力。因此,通过构建党建网络体系和党建教育信息库、网络党支部平台、网上党校平台、网上组织生活的在线交流平台等途径,可以行之有效地对大学生党员进行引导和教育。
