Evaluation of a mathematics program for preprimary children in rural Bangladesh

A randomized evaluation of a 9-month comprehensive math program for preprimary Bangladeshi school children addressed skills such as numbers, measurement, shapes, patterns, and space. Nine schools were randomly selected for the Intervention group and nine for the Control group, with 12 children randomly selected from each to participate in testing. Pre- and posttested scores on each unit's skills and a cumulative test at the end were subjected to analyses of covariance. Intervention children doubled their scores on almost all tests while control children increased only slightly. Reasons for the program's effectiveness were discussed.     

玉环柚籽中脂肪酸的GC/MS分析

以乙醚为溶剂,用索氏提取法,对产于浙江玉环县的玉环柚子籽油提取后,采用氢氧化钾-甲醇法对其进行了衍生化.然后利用气相色谱-质谱联用的方法对其衍生物的化学成分进行了分离鉴定.通过检索NIST98谱图库,最后从玉环柚籽油中分离确定了13种脂肪酸,其中大多数为不饱和脂肪酸.同时运用峰面积归一化法通过G1701BA化学工作站数据处理系统测得各化学成分在脂肪酸中的相对百分含量,为玉环柚籽油的开发利用提供科学依据.     

Writing culture; inscribing lives: a reflective treatise on the burden of representation in native research

This paper complicates the contested assumptions surrounding native research by exploring the burden of representation placed on native researchers because they are seen as insiders. This particular issue of representation is important for native researchers to consider, especially in instances where the research is on an understudied or politically charged group, because of the ways in which the socio-political climate influences both the telling and the reading of such research. Drawing on the author’s personal struggles as a Pakistani researcher conducting ethnographic research with Pakistani immigrants in the United States in the post-9/11 climate, this paper explores and critiques the role of the native researcher and the issues involved with representing understudied groups. Specifically, the paper focuses on authenticity, positionality, audience, and accountability. Thus, the paper is a call for researchers to be more reflective and to think more deeply about their positionality and its impact on the various constituents as they research and write. To encourage such reflexivity, the article provides a set of questions for researchers to consider at different stages of the research and writing process.

Mg／Al／Cu类水滑石焙烧产物对茜素黄GG的吸附

采用共沉淀法以不同的Mg^2＋、Al^3＋与Cu^2＋摩尔比制备一系列的镁铝铜三元类水滑石（Cu／Mg／Al—HTLc）。并研究了镁铝铜类水滑石的焙烧产（HTLc-500）对阴离子染料茜素黄GG的吸附特征。分别考察了不同镁铝铜摩尔比的HTLc－500、吸附剂投放量、反应温度、染料的初始浓度等因素对HTLc-500吸附阴离子染料茜素黄GG的影响。结果表明,对于合有20mg／L的茜素黄GG模拟废水溶液,镁铝铜摩尔比为8：10：22的类水滑石,投放量为25mg。在25℃下反应360min。去除率可达到99．14％。

改革现阶段高校英语专业翻译教学管见

随着我国经济的快速发展和国际地位的日益提高,政治、经济、文化等各个领域、各个层面的国际交往也越来越频繁,对翻译人才的需求急剧增大。统计数据显示,我国目前翻译人才存在很大的缺口,翻译人才的培养已远远不能适应社会发展的需要。目前,英语专业翻译教学普遍存在的问题是：教学目标落后于社会需求;教学目的不明确;教学科目设计单一,缺乏有效的测试手段。针对以上四个方面的问题,本文提出了几个改进教学的策略：重新定位教学目标;扩大授课内容设计的专业领域;建立翻译课程体系;将NAETI考试纳入英语专业翻译能力评定。
