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.     

Comparison of Mean-Risk Efficient Portfolios in Asia-Pacific Capital Markets

In order to analyze the performance of mean-risk efficient portfolios, several methods of portfolio comparison have been developed. In this paper we analyze the second-order stochastic dominance efficiency of portfolios on the mean-risk efficient frontier assuming that the risk is represented by standard deviations and concordance matrices set up on the basis of Pearson's linear correlation, Spearman's rho, or Kendall's tau. Empirical analysis of the market returns of selected Asia-Pacific stock markets is carried out considering both the U.S. dollar and euro as reference currencies, and different periods: before and during the subprime crisis. Measures and portfolios on the mean-risk efficiency frontier that should be of interest to at least one risk-averse investor are empirically documented.     

中国股票市场风险和收益风格效应的非参数检验

本文利用Kendall协同系数检验考察我国股票市场风险和收益的风格效应。通过实证研究首次发现各风格指数的收益率、总风险及指数特有风险均具有明显的分层结构,风格效应显著。对影响风险和收益的风格因素进行的分析表明:股票风险受规模因素的影响十分明显;而股票回报率受价值因素的影响比较显著,受规模因素的影响不明显。并进一步用Spearman相关系数考察了风险与收益之间的秩相关性。本文研究结果对资产配置和风险监管等问题具有参考价值。     

基于和谐管理理论的日本型经营体系再探讨

21世纪的今天，曾经辉煌的日本型经营的发展与变化，引起了研究日本社会变化的广大学者的关注．笔者认为，现代日本型经营体系，是以日本企业和管理者的管理哲学一一“和谐”管理思想基础上构建的。在国际化浪潮涌向世界每一角落的今天，“面向复杂性，和谐管理理论的概念、原则及框架”的构建，是21世纪经济模型建立的基础之一，基于“和谐”管理理论的日本型经营体系的再探讨，是和谐管理理论在实践中的尝试．     

Making patient medication safer for all: an action research approach

Complexity in medication arrangements can lead to risks for older people and their carers. These risks need to be managed through a system without any single hierarchical command and control structure. The paper describes the processes by which an action research project created a network organization for the safer consumption of medication in the community. Service redesign outcomes are recorded. The applicability of the approach to other complex products‐in‐use is noted.     

一项基于语境共现的教学活动——高职学生对assure和ensure用法掌握情况的调查

语料库以其容量大、语料真实、检索快捷准确等独特的优势在现代语言学研究和语言教育中正发挥着越来越重要的作用。该文通过开展一项基于语境共现的教学活动调查高职学生在活动前后对assure和ensure用法掌握程度上的差异，进一步证明利用语料库进行英语教学的巨大优势。     

Tracking the technological composition of industries with algorithmic patent concordances

ABSTRACT

Patents are a useful proxy for innovation, technological change, and diffusion. However, fully exploiting patent data for economic analyses requires linking patents to measures of economic activity, which has proven to be difficult. We construct probabilistic linkages between the U.S. Patent Classification (USPC) system and Cooperative Patent Classification (CPC) system and industry and product classifications including the North American Industrial Classification System (NAICS), International Standard Industrial Classification (ISIC), Harmonized System (HS) and Standard International Trade Classification (SITC). We use these concordances to evaluate the persistence of technology-industry relationships over time by generating linkages over different years of patent data. We find strong persistence in technology usage within industries and, until recently, relatively little change in the technology composition of industries over time. As the technology composition of industries becomes more stable, we find evidence of increased specialization. Finally, we show that industries that exhibit changing technology composition also show shifting occupational composition.
