Complementary feeding patterns among ethnic groups in rural western China

Objective

This study investigated complementary feeding practices among four ethnic groups (Han, Uygur, Tibetan, and Zhuang) based on a cross-sectional survey in rural western China.

Methods

In 2005, a stratified multistage cluster random sampling method was used to recruit 9712 children (7411 Han, 1032 Uygur, 678 Tibetan, and 591 Zhuang) between 6 and 35 months of age and their mothers from 45 counties in 10 provinces (autonomous regions, municipalities) in western China.

Results

The rates of early introduction (before 6 months) of complementary foods in four ethnic groups (Han, Uygur, Tibetan, and Zhuang) were 71.30%, 95.95%, 82.40%, and 72.30%, respectively. The Infant and Child Feeding Index (ICFI) for Uygur and Tibetan children was lower than that for Han children at all age groups. Uygur children were more likely to have unqualified ICFI compared with Han children in a multivariate logistic regression (odds ratio (OR)=5.138, 95% confidence interval (CI): 4.340–6.084). A higher level of maternal education, greater family wealth, and the availability of complementary feeding educational materials decreased the likelihood of an unqualified ICFI. The nutritional status of children (Han, Tibetan, and Zhuang) with qualified ICFI was better than that for children with unqualified ICFI.

Conclusions

Appropriate interventions are required to improve complementary feeding practices in rural western China.

     

电力市场的输电阻塞管理模型

讨论了电力市场的输电阻塞管理同胚，根据电力市场交易规则、输电阻塞管理原则，建立了相应的数学优化模型，算出了各模型对应的配电方案。最后。利用计算机模拟求得在不致引起输电阻塞时最大的市场负荷需求为983．2MW，在不致引起拉闸限电时最大的市场负荷需求为1094．6MW，并对模型的具体算法进行了讨论。     

略论构建学习型社会中的电大系统建设

实现高等教育大众化是我国教育发展战略中的系统工程，电大是构成这项系统工程的重要组成部分，控制系统的决策部门只有科学地划分系统内各于系统的职能和任务，才能使系统处于良性态势。电大在实施网络环境下的现代远程教育中加大了投入，为建立我国现代远程教育公共服务体系奠定了重要的物资基础，应该成为我国现代远程教育公共服务体系的主体。加强和完善电大系统建设是电大本身发展的需要，也是实现我国高等教育大众化的需要，对此，各级电大都有义不客辞的责任和义务。

论“通识”与“通识教育”

通识在本体论与认识论层面 ,是对常识、对科学的超越 ,在人生观与价值观层面 ,通识是对人的生命本然、终极目的与理想等意义世界的观照。在物质化与科技化的今天 ,人类需要特别关注通识。然而 ,达至通识之境并非自然自发过程 ,而是一个自为自觉过程。人类的通识 ,需要教育的参与、引导、培育和建构     

EFL teachers’ perceptions of English language policy at the elementary level in Taiwan

Due in large part to the trends towards economic globalization, English has become the most widely disseminated and ubiquitous international language. The purpose of the study was to investigate what Taiwan’s EFL teachers at the elementary level believe about the policy of English as a compulsory subject and how they perceive the benefits and obstacles of the policy’s implementation. Ten elementary English teachers in Tainan City and its suburban areas participated in this study. Data were collected through teachers’ interviews, classroom observation and document analysis. Results found that all ten teachers agreed with the policy for English as a compulsory subject at the elementary level. They observed both positive and negative sides of this top‐down policy. Classroom observation and interview data revealed that EFL teachers had to plan their English classes with the constraints on a large class of students with mixed levels of proficiency, limited teaching hours and resources. Parents’ expectations of and attitudes towards English learning also became an obstacle.
