把云南建设成为泛珠三角与东盟电力合作走廊的构想

加强能源合作是时代的必然选择。电力合作作为能源合作的重要组成部分,理应成为合作的重要内容。云南良好的区位条件和资源基础,有望成为泛珠三角与东盟电力合作的重要走廊。一旦该走廊建成,将对中国与东盟的能源安全体系建设产生重要影响。云南应紧紧抓住当前中国与东盟关系不断改善的机遇,加快中国———东盟电力合作走廊建设。     

控制权转移、民营化与财务报告质量:相关研究评述与启示

随着我国资本市场的发展和国有资本的战略性退出,控制权转移的上市公司在数量和比例上进一步增加,尤其是大量国有企业转变为民营企业。如何评价控制权转移后财务报告质量变化,以及如何提高中国企业民营化趋势中财务报告质量,具有重要的现实意义。本文对国内外关于所有权转移的研究成果尤其是国有企业民营化研究进行了简要的回顾与评述,并提出了在此领域后续研究应当关注的问题,以期对我国研究民营化对财务报告质量研究提供参考。     

Institutional failure or market failure?

We investigate the effect of the power of creditors, property rights protection, and institutional quality, on bank profits using a panel of 498 banks from 46 countries. Results show that better institutions and stronger property rights protection reduce bank profits, while stronger power of creditors drives up bank profits significantly. Results imply that better institutions and enhanced property rights protection lead to greater flow of credit allowing firms and investors to undertake more profitable ventures. By extension, stronger creditor rights erect steeper barriers to external finance for firms and investors. National indicators of economic freedoms may be more important to lowering the spread than strict creditor rights. Seemingly, credit markets fail when economic institutions fail or when governments intervene into these markets in ways that impede the safety and soundness of financial transactions and private contracting.     

Development and Psychometric validation of the Diabetes Therapy-Related QOL (DTR-QOL) Questionnaire

Abstract

Objective:

We developed and evaluated the psychometric properties of the Diabetes Therapy-Related QOL (DTR-QOL) as a disease-specific, self-administered questionnaire to assess the influence of diabetes treatment on patient QOL, regardless of treatment method.

Methods:

This new questionnaire was developed and validated in a standardized manner: Item development, pilot-testing and psychometric validation. A survey was conducted using the provisional version of the questionnaire, and reliability and validity were evaluated with psychometric testing.

Results:

The provisional version of the questionnaire was generated with 29 items through literature review and pilot testing. For psychometric assessment, analyses were performed on the responses of 284 adult Japanese patients with diabetes. Factor analysis by the principal factor method with promax rotation revealed 4 factors; “burden on social activities and daily activities” (13 items), “anxiety and dissatisfaction with treatment” (8 items), “hypoglycemia” (4 items), and “satisfaction with treatment” (4 items). For reliability, the intraclass correlation was 0.92, and Cronbach’s alpha coefficient was 0.94, indicating adequate test-retest reliability and internal consistency. For known-group validity, there were significant differences in scores for following variables: age, diabetes type, HbA1c, treatment method, glycemic control, hypoglycemia, nocturnal hypoglycemia, concern about weight gain, health status (patient assessment), and degree of communication with physician.

Conclusions:

The DTR-QOL, with good reliability and validity, can assess the influence of diabetes treatment on patient QOL. The DTR-QOL can be used regardless of treatment method that patients receive, and this characteristic enables to detect a difference on patients QOL between treatment methods before and after a switch of treatment. Limitations of this study include representativeness of the patient sample. The relatively small number of patients with type 1 diabetes should be noted. Also, responsiveness of the DTR-QOL has not yet been examined.
