Researcher vulnerability: implications for educational research and practice

This paper explores the concept of researcher vulnerability through a review of the extant research literature and each author’s feelings of vulnerability connected to their research with vulnerable populations while exploring both sensitive and seemingly innocuous, yet important, topics in education using qualitative methodology. Specifically, a reflection of our respective study of the academic and social transitions of student combat veterans, and the academic and gender socialization of adolescent African American males is presented as means of illustrating the phenomena of researcher vulnerability. Implications of vulnerability for research, practice, and theory are discussed.     

英国高校学科评估的现状分析

在高等教育大众化、教育资源短缺等因素的影响下,英国在1993～2001年间进行了规模宏大的高校学科评估。学科评估提升了教学在英国大学的地位,但也存在如耗资巨大、评估体系不完善、高校学术自主受到侵蚀等问题。英国从2002年开始的新的质量保证体系“院校审核”试图解决这些问题。英国的学科评估正处于不断改进之中。     

A Review of Practical Reasoning in Child and Youth Research

The purpose of the review is to investigate various relations between the concepts of competence and participation found within child and youth research with the aim of identifying differences in practical reasoning of the various kinds of child research. The search identified 260 articles, and an in-depth analysis of 39 articles was conducted, elaborating the conceptual differences inherent in the different child research fields. Based on a philosophy of practice, the analysis identified 3 different causal connections between the concepts of competence and participation, indicating 3 different ways of understanding means and ends in child research. The review thereby offers an understanding of how and why interdisciplinary problems sometimes occur in education and child care.

Barriers to environmental education: How do teachers’ perceptions in rural Ecuador fit into a global analysis?

Abstract

We identified 48 barriers to teaching environmental education reported by teachers in global literature and compared frequency to empirical data we collected from rural Ecuador, part of an understudied region and continent. We utilized Q methodology and interviews with 25 (78%) teachers at 6 schools to identify and categorize barriers. Perceptions of barriers ranked by Ecuadorian teachers were statistically classified into three factors: logistical (associated with fieldtrips, time, and money); training and lack of government support; and attitudinal (associated with student disinterest). In contrast, barriers related to student testing and controversial topics were only reported in more developed countries. Results enable region-specific recommendations.     

基于网络的英语阅读教学实践研究

合著者贡献率的国际文献回顾

本文对合著者贡献率的国际文献进行了回顾,分析了修正Harmonic算法,CCA分配法,夏普里值法,Ab-index以及NBA算法等作者贡献分配率算法的优缺点。结果表明:修正Harmonic算法在评价作者贡献时仅仅区分第一作者,年长作者和其它作者,评价算法相对简单。CCA分配法通过常数K,调整了合著者之间的贡献分配,CCA算法合著者贡献率取值在Fractional和Harmonic算法范围之间。夏普里值法通过界定具体的边际贡献细节确定某一作者在合著中的边际贡献,但计算过程复杂。Ab-index明确区分了第一作者,通讯作者和其它作者的贡献;提出了适合各年龄层次的作者区分度方法,易于操作。NBA算法贡献率分配指数随着学科不同而取不同的值。     

Peering inside research networks: Some observations on the effect of the intensity of collaboration on the variability of research quality

Although there is some general agreement that increasing levels of collaboration amongst academics produce research papers that receive more citations, and that larger numbers of citations often imply higher quality, the issue of collaboration and its effect upon research output remains a controversial area with a wide range of views of what role collaboration plays and its general implications for quality. This paper re-examines the process of collaboration within research networks. It considers the role of collaboration and its effect on quality by studying the relationship between the level of interaction within research networks (collaboration) and the extent of variability of quality within those research networks. Twenty-two scientific networks from Austria are examined. The findings of the analysis are that increasing levels of collaboration are strongly associated with lower levels of variability of quality within each network. The conclusion is therefore drawn that collaboration at the level of the research network acts upon research quality qua peer review and that this peer review effect is inherent throughout the research process.

静液挤压过程中的流体动力润滑研究

研究静液挤压过程流体动力润滑状态形成的条件,推导静液挤压过程工件与模具表面间润滑油膜厚度的计算公式．通过Ｒｅｙｎｏｌｄｓ 方程和塑性加工润滑理论推导了形成流体动力润滑的临界速度计算公式和润滑油膜厚度的计算公式,并对上述公式进行了实验验证．由临界速度计算公式所计算出的理论数值和实验所测数值基本吻合,该临界速度计算公式可作为静液挤压过程中是否形成流体动力润滑判据;润滑油膜厚度的变化往往对工模具表面间的摩擦系数、挤压过程的稳定性有很大程度的影响,可以根据本文提出的润滑油膜厚度的计算公式结合实际工况条件通过合理调整工模具各参数的数值以使得油膜厚度值达到一个理想的数值,从而对静液挤压过程进行优化设计．
