A systematic review： How to choose appropriate health-related quality of life （HRQOL） measures in routine general practice？

INTRODUCTION The ultimate goal of health care is to maintain or improve the quality of life of people. Health is an important determinant of a person’s quality of life although it is not the only one. Other factors such as culture, religion, environment, education and finance can also affect quality of life but they are often be- yond the scope of health care.

Science Letters:Crossover randomized controlled trial of the electronic version of the Chinese SF-36

Objectives:to verify the feasibility and reliability of the electronic version of Chinese SF-36 based on the Quality-of-Life-Recorder. Design: A crossover randomized controlled trial, comparing a paper-based and an electronic version of the Chinese SF-36, was conducted. According to generated random numbers, interviewees were asked to fill out either the electronic version or the paper version first. The second version was filled in after a pause of at least 10 min. Settings and participants: One group of 100 medical students at the School of Medicine of Zhejiang University and the other group of 50 outpatients at a clinic for general practice in Hangzhou City (China) were eventually recruited in this study. Results: The acceptance of the electronic version was good (60% of medical students and 84% of outpatients preferred the electronic version). At the level of eight-scale scores, the mean-difference for each scale (except for general health) between the two versions was less than 5%. At the level of 36 questions, the percentage of "exact agreement" ranged within 64%～99%; the percentage of "global agreement" ranged within 72%～99%; 77% of the kappa coefficients demonstrated "good/excellent agreement" and 23% of the kappa coefficients demonstrated "medium agreement". Conclusion: This study, for the first time, can provide empirical basis for the confirmation of the feasibility and reliability of the electronic version of the Chinese SF-36 and may provide an impulse towards widespread deployment of the Quality-of-Life-Recorder in Chinese populations.

Math for the Benefit of Society: A New MATLAB-Based Gen-Ed Course

Abstract

Responding to a call for national reform of mathematical education, as well as a college-wide revision of general education (GE) requirements, we describe a new entry-level, GE course focused on the humanitarian utility of mathematics. This includes a detailed overview of how we taught the course using a Humanitarian MATLAB Lab Manual developed collaboratively with undergraduate students within an applied math program. A PRIMUS edition of this manual with complete MATLAB materials for a GE course is included as an Appendix for interested readers. A variety of social justice issues including peace-building after modern civil wars, continued cancer risk after Chernobyl, gang reduction, various dimensions of human trafficking, the use of a tractor and herbicide in subsistence farming, equitable resource distribution during the Syrian refugee crisis, and access to HIV vaccines are included in this special edition of the manual.     

内向型、外向型性格与英语学习

中国学生的性格特征与其英语学习关系密切。内外向性格差异在英语学习中会呈现出不同的相对优势和弱势，此状况对指导英语教学实践意义重大。采用定性分析方法，结合相关教学理论，分析具有不同性格的学生在英语专业学习各方面的具体表现。掌握学生实际，进行针对性教学，培养学生的听、说、读、写、译等综合技能，能充分激发学生专业学习兴趣与潜能。     

索绪尔的比喻及其普通语言学理论

索绪尔的论著《普通语言学教程》是他的学生巴利 (CharlesBally)和塞什艾 (AlbertSechehaye)根据课堂笔记整理成书的。在该书中 ,索绪尔阐述了他的普通语言学理论 ,其中有许多抽象的概念 ,不加以细心的琢磨是难以理解的。也许正是考虑到这一点 ,索绪尔用了一系列的比喻将这些抽象概念具体化 ,便于学生更好地接受。今天我们阅读此书从这些比喻入手 ,可以更清楚地了解索绪尔普通语言学理论中的许多核心概念     

微分法在一类特殊常数项级数求和中的应用

本文介绍了一种通过构造幂级数求解常数项级数和的方法。该方法运用逐项微分法将幂级数的收敛和函数转化为相应的常系数线性微分方程,求出微分方程的通解从而得到相应常数项级数之和。并给出了相应的定理和例题来说明这一方法。
