传统成本法问题研究

科技发展和市场竞争 ,是传统成本法造成不同产品之间的“成本转移”问题的基本原因 ;批量差异、工艺差异、品种规格差异是三种常见的“成本转移”形式 ;“成本转移”使产品成本信息失真 ,并导致经营决策失误、成本控制失败 ,最终降低企业的竞争能力和盈利能力     

Unitary, Divisional, And Matrix Forms As Political Governance Systems

In this study I reassess a set of fundamental organization forms (unitary, divisional, and matrix) as agenda-setting and political governance systems. My method of analysis is based on how political scientists study agendas in committees. Specifically, I first recount that moving from a functional (unitary) to a product-line (divisional) structure increases the types of conflict referred from lower to higher levels of the hierarchy, but does not increase the amount of conflict referred. I then show that moving from a product-line to a matrix structure increases the amount and the types of conflict referred to higher levels of the hierarchy; that it is possible in matrix forms that no conflict is resolved at the lowest levels of the hierarchy; and, that accountability is reduced for those who are able to refer conflict. The study reveals implications for matrix forms that derive from this view of organizations as agenda-setting and political governance systems. This analysis fits with the recent history of matrix forms in a variety of organizations.     

Copula及其在贷款风险管理中的应用

相关性是贷款组合管理的关键性因素.本文介绍研究相关性的一种统一而灵活的工具--copula,并使用Monte Carlo仿真方法对高斯copula和t-copula进行比较,结果表明,t-copula对度量服从厚尾分布的贷款风险比高斯copula更精确.     

基于层次分析(AHP)的公共交通枢纽换乘衔接模糊评价

对公共枢纽的换乘衔接进行评价涉及到很多方面的因素，是一个半定性、半定量问题．本文采用系统工程学的层次分析方法建立了评价指标体系．并对不同指标赋予了权重：在此基础上提出了对公共枢纽的换乘衔接进行评价的模糊评价方法，并给出了算例分析。     

论农村家庭联产承包责任制在当代的发展趋势

农村家庭联产承包责任制在历史发展过程中起过积极作用，但农村家庭联产承包制在实施过程中也暴露出一些问题。现时代为保持农村生产力持续快速发展，就应进一步完善农村家庭联产承包责任制，而实现“土地流转”并最终建立家庭式的“红色农场”就是完善农村家庭联产承包责任制的大胆设想，因为，它顺应了大农业发展的趋势，代表着中国农业的长远发展方向。     

Measurement equivalence of Watson and Clark's 18 surrogate measures of negative affectivity: Applying the principle of tetrad differences to an incomplete correlation matrix

Watson and Clark concluded, based primarily on a subjective analysis of the positive manifold of 87 intercorrelations, that 18 personality measures were manifestations of the same stable and pervasive trait of negative affectivity. Confirmatory factor analysis to test a one-factor measurement model was not possible, since only an incomplete matrix of correlations (87 out of 153) was available. In this paper, the principle of tetrad differences was applied to an incomplete correlation matrix to test for a general factor across the 18 measures. This principle assesses the equivalence of different measures hypothesized to tap into the same construct. Of the 614 first-order partial correlations, only 44 (7.2%) failed to satisfy the principle of tetrad differences, indicating support for a common underlying trait. In addition, confirmatory factor analysis and Herman's one-factor test provided support for a general factor across a subset of the 18 scales for which a complete matrix of correlations was available.

Spectral properties of the concurrent and forecasting seasonal linear filters of the X-11-ARIMA method

This study analyzes the properties of the linear filters of the X-11-ARIMA seasonal adjustment method applied for current seasonal adjustment. It provides the general formula for the combined weights that result from the ARIMA model extrapolation filters with the X-11 seasonal-adjustment filters. The three cases studied correspond to the three ARIMA models automatically tested by the X-11-ARIMA program, namely, (0, 1, 1)(0, 1, 1), (0, 2, 2)(0, 1, 1), and (2, 1. 2)(0, 1,1). The parameter values chosen reflect different degrees of flexibility of the trend-cycle and seasonal components. It is shown that the X-11-ARIMA linear filters for current seasonal adjustment are very flexible; they change with both the ARIMA extrapolation model and its parameter values, contrary to those of the X-11 program, which are fixed for a given set of options.
