Analysis of cointegrated VARMA processes

VARMA (vector autoregressive moving average) processes are proposed for modelling cointegrated variables. For this purpose the echelon form is combined with the error correction form. Procedures for estimating the Kronecker indices which characterize the echelon form and for specifying the cointegration rank are discussed. The asymptotic distribution of the coefficient estimators is given. An example based o n US macroeconomic data illustrates the procedure and demonstrates its feasibility in practice.     

Assessment of Interjudge Reliability in the Open-Ended Questions Coding Process

In the process of coding open-ended questions, the evaluation of interjudge reliability is a critical issue. In this paper, using real data, the behavior of three coefficients of reliability among coders, Cohen’s K, Krippendorff’s α and Perreault and Leigh’s I _r are patterned, in terms of the number of judges involved and the categories of answer defined. The outcome underlines the importance of both variables in the valuations of interjudge reliability, as well as the higher adequacy of Perreault and Leigh’s I _r and Krippendorff’s α for marketing and opinion research.

结果质量与过程质量探析

服务营销专家格罗鲁斯认为，服务质量包括两方面内容：结果质量与过程质量。但对于结果质量与过程质量孰轻孰重，是一个在理论上和实际生活中都未能很好解决的问题。文章在回顾相关理论的基础上，认为判断服务结果质量与过程质量孰轻孰重不能一概而论，而应综合考虑行业、顾客和社会文化等因素，将提升服务质量的努力放在不同的方面。     

基于AHP的模糊综合评价法在连锁经营伙伴选择中的应用

本文提出了加盟盟主对盟员选择的指标体系,并在此基础上应用基于AHP的模糊综合评价法对盟员进行评价。该方法不仅可以确定“准加盟者”的排序,而且可以确定各自的等级。     

施工项目管理业务流程存在的问题分析

良好的施工项目管理流程是运用现代化的管理，把项目所需的各种物质和信息进行有机的结合，从而保证项目的顺利实施和项目的实现，但实际工作中却存在一些问题，如：缺少某些重要环节，个别管理流程不明确，致使有关管理工作不到位，有的管理流程颠倒，起不到应有的作用等等，使得施工项目管理流程起不到应有的作用。本文围绕这些问题进行了详尽的分析和探讨，并结合笔者多年的从业经验提出了科学合理的施工项目管理业务流程，具有很强的实践性与可操作性。

An alternative employee rights paradigm: Labor process theory

A dialectical relationship exists between the capitalist desire for accumulation of wealth and profits, and the rights of employees. Labor process theory exposes facets of the fundamental incongruity between the interests of employers and workers in a capitalist political economy. An analysis of employee rights through the labor process framework facilitates the potential for human emancipation by illuminating the ideological, political, and economic sources of domination and repression that are embedded in the capitalist system. In this article, three core elements of labor process theory—the social relations of production, the managerial control imperative, and the restructuring of work—are used to highlight ways in which organizations maintain their hegemonic position. This exposé offers the basis for an alternative paradigmatic view of the employment relationship and informs our thinking of how employee rights are impacted, and often tempered, in work organizations. Portions of this article were presented by both authors at the 12th Annual International Labour Process Conference March, 1994 in Birmingham, England.
