Noncognitive Constructs and Their Assessment in Graduate Education: A Review

We reviewed the literature on "noncognitive" predictors-specifically, personality as it pertains to graduate education. The review is divided into 3 sections. In the first section, we reviewed measures typically used in studies of graduate school outcomes, such as attrition and time to degree. We also reviewed which student qualities faculty and administrators said they desired and cultivated in graduate programs. We also noted that there are many qualities faculty ranked high in desirability but which could only imperfectly be gleaned from sources such as letters of recommendation and personal statements. In the second section, we reviewed general personality factors (e.g., the "Big Five"), specifically, definitions, measures, correlates, and the validity of those measures. We concluded with a discussion of how personality factors might be used in admissions and guidance applications for graduate education.

Caregiver-Parent Relationships in Daycare: A Review and Re-Examination of the Data and Their Implications

This paper reviews and examines critically the literature on caregiver-parent relations in daycare centers and family daycare homes. This literature is characterized by attempts to understand (and evaluate) the social changes and accumulating data regarding formal non-relative childcare in terms of the dynamics of informal, familial forms of care. Instead, it is argued that informal and formal care arrangements are qualitatively different, that neither type is inherently superior, and that each needs to be understood in terms of its own unique systemic and contextual characteristics. Viewing the data on formal care arrangements from this perspective, it is proposed that, 1) contrary to current interpretations, caregivers' ambivalent and critical attitudes toward parents are neither surprising nor a risk factor for children. Rather, these attitudes are an inherent component of the consumer/provider structure of the caregiver-parent relationship system and may actually facilitate the caregivers' involvement with the devalued parent's children; b) the high rates of parental satisfaction with daycare reflect neither a wholehearted endorsement, nor an adequate assessment of care quality. Rather, high satisfaction rates are one product of parents' attempts to cope with perceived marketplace constraints. Further, the narrow focus of the satisfaction research to date has also prevented us from adequately understanding parental perceptions of childcare and how they shape pertinent decision making processes; c) the documented low rates of caregiver-parent contact are an inherent feature of the professionalization process in the daycare system and are not a sufficiently useful indicator of the quality of caregiver-parent relationships; research in this area should expand to explore the relationship's potential buffer function.     

管理理论评述与协调管理理论的建立

文章论证了协调管理理论经历的历史的进化过程,即从经验管理、纯理性主义科学管理、初级人本主义管理、X理论、Y理论、超Y理论、Z理论到理性主义与非理性主义相结合的协调管理.在复杂性科学与东方传统文化基础上建构了具有东方管理特色的协调管理理论,实现了现代管理理论与复杂性科学、东方传统文化的有效嫁接,并阐明协调管理理论的组织路线图是“1+1＞2”的蛹动螺旋式的超循环,其组织图谱是对立统一的、非线性的、具有灵魂与生命的旋极图.

Applications of Temperament: A Review of Caregiver-Focused Temperament-Driven Interventions

Research Findings: Temperament, often defined in terms of reactive and regulatory tendencies, has been shown to predict child outcomes over and above other risk factors and represents a critical aspect of social-emotional development. The present article is a systematic review of temperament-based interventions targeting caregivers, wherein the aim is to inform caregivers about temperament in an effort to influence a variety of outcomes, such as goodness of fit, parenting stress, achievement, and behavior problems. In total, 13 randomized and nonrandomized trials were reviewed, with promising outcomes. Temperament-driven interventions have demonstrated the capacity to increase parental knowledge of temperament, reduce behavior problems, improve math and reading achievement, create more positive teacher–child relationships, and reduce numbers of medical visits. Caregivers report satisfaction with and usefulness of the interventions, which suggests promise for future application of temperament-based approaches. Temperament-driven interventions can be leveraged to improve multiple developmental outcomes, especially in early childhood, and are useful for both teachers and parents. Practice or Policy: Implications of temperament-based interventions for early childhood educators are discussed, as are limitations and future directions.

我国幼儿园环境创设研究述评

20多年来,我国幼儿园环境创设研究经历了初步研究、进一步发展和多元化研究三个阶段。幼儿园环境创设研究的主要内容,涉及幼儿园环境创设的价值、具体方式、环境创设的有效性、环境创设中存在的问题与对策建议等方面。目前我国幼儿园环境创设研究还存在着重微观轻宏观研究;重视心理学、教育学研究,忽略多学科研究;研究方法单一,研究结果不明确等问题。环境创设应从多学科角度、结合多种研究方法进行生态的研究;关注不同类型幼儿园环境创设的研究;关注幼儿园环境创设的评价;同时高校学前教育专业的课程设置应该考虑环境创设的问题。

Women in Science, Engineering and Technology: A Review of The Issues

Concern continues to be expressed over women's difficulties in advancing their careers as academic scientists. Though some sciences may be numerically 'feminised', few women reach the upper echelons of science. Scant attention has been paid to issues of the progression of women from non–traditional backgrounds, such as those from ethnic minorities, who may be particularly disadvantaged. What research there is indicates a variation between the sciences in terms of women's careers and patterns that are replicated globally. Explanations are now focusing on how the scientific culture itself acts as a barrier to women rather than on the notion that women themselves lack the requisite skills. The Athena Project is a policy response to this issue. Future research and policy needs to look more closely at differences between the sciences, how women from diverse backgrounds experience the academic labour market and epistemological connections between employment and engagement with the scientific agenda.     

我国地方课程研究的现状与反思

地方课程是我国课程研究领域重要的组成部分,也是当前我国基础教育课程改革实践中一个尚未引起充分关注的问题。新课程实施10余年来,我国在地方课程开发中进行了许多有益的尝试并取得了许多有价值的研究成果。然而伴随地方课程建设的逐步深入,碰到的困难和问题还很不少。因此,对地方课程10年来的改革进行盘点,并在此基础上对地方课程的未来发展走向作出预测,既具有理论意义,也不乏实践价值。
