学前儿童STEM教育：构成要素、理念及本土化

学前儿童STEM教育是由儿童、环境、教师等构建的科学素养取向、儿童本位取向和实践取向的全方位、立体化整合系统。整合作为学前儿童STEM教育的本质属性在构成要素上呈现为以知识概念融通为核心基础,以情境因应为外驱力,以儿童的学习思维为内驱力,以学习共同体的交往实践为助推力,在理念上凸显批判性和假设性的知识观,实践性和交往性的学习观,开放性和生成性的教学观以及真实性与虚拟性的情境观。学前儿童STEM教育的本土化应在分析共性教育要素的基础上应扎根历史文化,从价值重塑,本体重构和认知重建三个维度进行转化。     

国内所有权保留买卖合同中标的物风险移转新论

所有权保留买卖作为现代民法权利分化的一种现象,在买卖双方以及第三人之间是一种独一无二的利益平衡方式。然而,国内所有权保留买卖合同标的物风险的转移没有明确规定,可以按照交易时的环境和条件,由能够控制风险的一方当事人承担标的物转移毁损、灭失的风险,较能实现当事人的利益平衡。     

Academic and Behavioral Outcomes Among the Children of Young Mothers

In this article, we use newly available data from the National Longitudinal Survey of Youth to investigate the effects of early motherhood on academic and behavioral outcomes for children born to early child bearers. We find that early motherhood's strong negative correlation with children's test scores and positive correlation with children's grade repetition is almost entirely explained by prebirth individual and family background factors of teen mothers themselves. However, early childbearing is associated indirectly with reduced children's test scores through its linkage to family size (and thus to child birth order). We find a different pattern in predicting fighting, truancy, early sexual activity, and other problem behaviors among adolescent and young adult offspring. For these behaviors, maternal age at first birth remains an important risk factor even after controlling for a wide range of background factors and maternal characteristics. These results highlight the diverse pathways through which teen parenting might influence subsequent child well‐being and social performance.

At the intersection of science,technology, engineering,and mathematics and business management in Canadian higher education: An intentional equity,diversity, and inclusion framework

In this study, the authors address the persistent discrimination cis women face in the Canadian science, technology, engineering and mathematics (STEM) higher education context. Pulling on the notion of interrelationships that cross educational faculty boundaries and on intersectionality scholarship to unsettle the structural and disciplinary domains of power, the authors ask, “How can business education and STEM education work together with respect to social considerations, such as gender/race/ethnicity/etc., and social equity and inclusivity, within the Canadian higher education system?” This study aims to build on these interrelationships among diverse, complex individuals who participated in a graduate-level STEM and business management summer institute to provide an evidence-based and intentional equity, diversity and inclusion (EDI) framework for STEM higher education contexts. Using a mixed-methods approach, which saw data collection via a survey instrument and semi-structured interviews, the subsequent quantitative analysis points to expanding interrelationships to broader areas beyond STEM and business management programs. The close reading of the collected qualitative data, via antenarrative spirals, elevates the participants' complexities beyond focusing “just” on their intersecting identities to looking at their perceptions of STEM fields, the order that ensues and the potential for the undoing of that order. The findings, results, and analyses of these collected data led to an intentional EDI framework, the main contribution of this study, constructed into three main pillars represented by the figure of a tree: the foundational elements (roots) built on individuals' complexities and experiences of Othering, the interrelationships (trunk) possible across various educational and professional dimensions, and a call to structural change initiatives (branches) with the possibility for growth in other areas. This work then contributes to not only filling a significant literature gap and building awareness regarding EDI concerns in STEM contexts via active interrelationship-building activities but also to unsettling the structural and disciplinary domains of power by embracing a holistic strategy to address systemic discriminatory practices in the Canadian STEM higher education context.

Military service and STEM employment: Do veterans have an advantage?

We use five years of American Community Survey data to examine how military service provides a non-degree-based pathway into STEM occupations. Military service is associated with STEM occupations in positive and surprising ways. Veterans are more likely than their civilian counterparts to work in STEM, an effect particularly strong for women and among workers without a STEM bachelor's degree. Among workers lacking STEM BAs, veterans were more likely to hold STEM occupations. Indeed, veterans lacking a college degree at all are more likely than their nonveteran counterparts to hold STEM employment. We conclude that military service in itself provides a rarely-discussed route to diversifying STEM and consider the policy implications.     

乡村教师留任的环境因素及其改进措施--基于环境匹配视角

为研究环境因素对乡村教师留任的影响,对黑龙江省10个地区的乡村教师展开调研,显示有三点研究结果。第一,环境因素对乡村教师留任有独立且显著的影响。在单独分析环境因素的作用时,结果显示,不论有无背景因素参与,不同的环境匹配度对乡村教师留任都有显著影响,相比之下,低环境匹配度对乡村教师留任的影响更大。第二,不同环境匹配度下组织承诺的多重中介效应显著。高环境匹配度模型和低环境匹配度模型的研究结果均显示,环境因素通过组织承诺的中介效应显著地提高了乡村教师的留任率,相比之下,高环境匹配度对提高乡村教师留任率的作用更大。第三,支持性条件的调节效应显著。研究结果显示,支持性条件在环境匹配度与组织承诺水平、环境匹配度与乡村教师留任中起到显著的正向调节作用,相比之下,较好的支持性条件其调节效应更显著。从环境匹配角度看,留住乡村教师需要采取以下有效措施:改善支持性条件,提高乡村教师组织承诺水平;完善招聘与培养培训制度,提高乡村教师与乡村环境匹配度;建立乡村教师留任监控数据库,强化教育行政管理部门监测意识,完善问责机制。     

Modelling the role of anticipated emotions in blood donor behaviour: A cross-sectional study

For blood transfusion centres, studying anticipated emotions (AEs) related to blood donation is essential, since these variables influence donation decision. For this reason, this work addresses the need to identify the antecedents and consequences of AEs, which will help explain their origin and their role in donation behaviour. Our purpose is to make further progress with the application of the AE framework in a non-profit context, by analysing how AEs are generated and how they influence decision-making. This study aims to design and validate an explanatory model of donation intention, where motivations and attitude towards donation are direct antecedents of AEs, while AEs, motivations and attitude towards donation act as direct antecedents of intention. Moreover, it has been also considered how the type of donor influences the proposed model as a moderating factor. The final sample is comprised of 35,982 active donors, inactive donors and non-donors. Data was obtained through an online questionnaire, with the collaboration of 14 of the 17 Spanish blood transfusion centres, as well as some universities. Results indicate that (1) AEs, motivations and attitude towards donation are direct antecedents of donation intention, (2) motivations and attitude towards donation are direct antecedents of AEs, and (3) donation experience moderates the relationships between motivations, attitude towards donation, AEs, and donation intention. These results indicate several operational implications that will enable blood transfusion centres to better design and target donation promotion campaigns according to type of donor. Furthermore, the results will let centres assess whether placing value on donation motivation and attitude towards donation can bolster positive AEs, diminish negative AEs and have a direct effect on donation intention.     

The Role of Technology in Mediating Use of Outpatient Substance Abuse Treatment Services

ABSTRACT

This study examined the relationship between Connect, a telephone-based information and support system, and the use of outpatient substance abuse treatment services. Regression models were formulated to examine the relationship between use of substance abuse treatment services and Connect. The results indicate that Connect use was not significantly related to the likelihood of using treatment (N = 240). However, an inverse relationship was found between Connect and use of treatment services (n = 123). The findings raise the conceptual issue of whether one introduces technology as an “add-on” to or as a “substitute for” traditional substance abuse treatment services.
