Estimation and Prediction of Functional Autoregressive Processes

We present a generalization of some previous works (Bosq, Mourid, Pumo) about the functional forecast of a Banach autoregressive processes. We are mainly concerned with order p , p >1, autoregressive processes which appear to be a natural extension of the well-known R d -valued autoregressive processes to a functional framework. This modelization provides an new approach for estimating and for predicting a continuous time stochastic process over an entire time interval. Using results from [12] we prove asymptotic properties of estimators of the parameters and predictors which are based upon a principal component decomposition of a Hilbert-Schmidt operator with unknown eigenvectors.     

m阶积分算子及其应用

本文引人m阶积分算子，给出函数乘积u（x）．v（x）的m阶积分公式，此公式将函数乘积u(X)．v（x）的n阶导数的Leibniz公式推广到n为负整数情形，此公式同时也是函数f（x）的Taylor公式及Taylor级数的一种推广．     

绩效评价中主管评价与自我评价的差异性研究

通过386份数据,实证分析了员工绩效“自我评价”与“主管评价”结果差异与员工人口特征变量的关系。分析结果显示,在“入职时间”和“职位层次”两个人口特征变量上,自我评价与主管评价不仅总体评价结果存在显著性差异,而且在“工作业绩”、“工作能力”、“工作态度”、“合作意识”等四个维度上表现出不同程度的显著性差异。在“性别”变量上,“合作意识”维度表现出显著性差异;在“文化程度”变量上,“工作能力”维度表现出显著性差异;在“跳槽次数”变量上,“工作态度”维度表现出显著性差异。文章根据实证分析结论,提出了相应的提高绩效评价数据信度和效度的建议。

国有企业财务效绩与经营者效绩的作用关系研究

我国在国有企业效绩评价的实际操作中,往往将对企业的效绩评价与对企业经营者的效绩评价混为一谈,这样不能体现出经营者在主观上为企业经营管理所做的努力,不利于对经营者进行有效激励.本文提出将经营者效绩评价从企业效绩评价中分离出来,认为企业效绩应包括财务效绩和经营者效绩两个方面,进一步通过研究财务效绩与经营者效绩的形成过程,从而揭示出企业财务效绩与经营者效绩在形成过程中的作用关系,为企业建立更科学合理的效绩评价体系提供了新的视角.     

论场域资本运作对刑事司法的影响——以布迪厄资本理论为分析视角

刑事司法实践活动实际上是被限定在司法场域之中的.司法场域的行动者依其在该场域中所拥有的权利或权力资本而被分层,其对活跃在司法场域各种形式资本的竞争,主要是围绕着案件事实与法律适用的话语权而展开争夺的.司法场域行动者对刑事司法过程的影响,是在对场域权力或权利资本进行不断地争夺、交换、整合过程中实现的.场域行动者的资本权重越重,资本能量越大,在案件事实确认与法律规范适用方面的话语权就越重.     

N-stage splitting for maximum penalized likelihood estimation

An n-stage splitting algorithm for the solution of maximum penalized likelihood estimation (MPLE) problems is compared to the one-step-late (OSL) algorithm. General conditions under which the asymptotic rate of convergence of this splitting algorithm. exceeds that of the OSL algorithm are given. A one-dimensional positive data example, illustrates the comparison of the rates of convergence of these two algorithms.     

A simulation-based dynamic operator assignment strategy considering machine interference - a case study on integrated circuit chip moulding operations

A simulation-based dynamic operator assignment strategy is proposed considering machine interference in solving an integrated circuit moulding operation problem. The strategy iteratively solves a floating manpower operator-assignment problem between simulation-based diagnostic study and operator assignment decision. Given current-state information, it provides a means for system performance evaluation. It searches a satisfactory solution for both cycle time and service level performances by using floating manpower method. A structured experimental design is used to illustrate the effectiveness of the proposed methodology. Empirical results show promise for the proposed methodology in solving a practical application. Finally, the system implementation constraints from both hardware and management problems are addressed.
