脉冲电晕法处理含苯废气实验研究

挥发性有机物(VOCs)的污染与控制技术日益受到重视。近年来发展起来的非平衡等离子体技术在治理VOCs方面已初步显示其独特的技术优势,现已成为废气治理研究领域中的前沿热点课题之一。等离子体法降解VOCs的机理较为复杂,研究不同线路对VOCs降解过程的影响意义重大。采用脉冲电晕放电等离子体技术,建立了混合电晕、有机电晕、空气电晕和分别电晕4种不同的实验方案,选取苯为代表物质进行实验研究,在初始浓度、停留时间和电源参数等一定的条件下,考察脉冲电压对苯去除率的影响。结果表明,电压为140kV、混合电晕时苯的去除率达到82.73%,脉冲电晕技术处理低浓度有机废气效果较好。     

Changing roles in sustaining successful charter school leadership in high poverty schools: Voices from the field

Effective educational leadership is essential for the success of schools and ultimately student achievement. The impact of school leadership may be even more pronounced in charter schools. Due to current and unprecedented growth, unique design, and complexities of political, financial, and governance issues they face, there is a need for more highly qualified charter school leaders and perhaps even “differently” prepared leaders. In this qualitative study, the authors documented the characteristics and skills of two successful, sustained charter school leaders who retrospectively described their evolved and evolving roles over twenty five years. Each transformed high-poverty, low-performing schools with at-risk populations and led with vision, passion, and a relentless desire to positively influence their organizations and ultimately improve student success in their communities. Although many of their skills and characteristics fall within existing theories, such as situational leadership, transformational leadership, and distributive leadership, they embodied a level of dedication and commitment to the original communities in which they founded charters lasting over a quarter of a century. The findings suggest that founding a charter school and seeing it through to success over time may more closely resemble missionary work than traditional school leadership.     

Let's Talk About Maths: The Role of Observed “Maths‐Talk” and Maths Provisions in Preschoolers' Numeracy

Developmental cognitive neuroscience highlights the importance of interactions between children and their environment. As young children spend increasing time in childcare, it is key to investigate the impact of “maths‐talk” and maths provisions in preschools. Qualitative insights from early educators indicate a greater bias toward counting activities than would be expected given the Early Years curriculum. In addition, we quantified the observed breadth of preschool practitioners' maths language (e.g., place‐value language), setting‐based maths provisions (e.g., quality of maths‐related activities), and their relation with children's early numeracy skills. In settings with greater practitioners' breadth of maths language, children display greater cardinality skills although our data call for the further investigation of parental socioeconomic status and education. We conclude with a discussion on the need to operationalize children's maths learning environments as diversely as possible. Enriching practitioners' skill sets may be an effective and needed way of improving early maths outcomes.     

民族文化认同在体育锻炼与心理异常关系中的中介作用

为了检测体育锻炼和心理异常关系中民族文化认同的作用,对93名大学生进行体育锻炼、民族文化认同和心理异常的测量。结果发现：（1）民族传统体育锻炼时间的增长能缓解心理异常的发生;（2）民族文化认同的提高能缓解心理异常的发生;（3）民族体育锻炼的时间和民族文化认同是预测心理异常水平的重要因素;（4）民族文化认同在体育锻炼对心理异常的影响中起到中介作用。

An Early Endeavor to Apply Quality Concepts to the Systematic Design of Instruction: Successes and Lessons Learned

In 1988, two staff members in the design department at Motorola Training and Education Center (MTEC) began a self-initiated project to develop and implement a system to improve the quality of courses being developed for their customers. This article describes how they applied Motorola's six steps to Six Sigma quality to their instructional design activities. While their quality system was not institutionalized throughout the instructional design department, several valuable lessons were learned that might benefit others embarking on a similar endeavor. Lessons learned dealt with: the sample of customers used to determine customer requirements, product-specific customer requirements, a continuous improvement system within the context of an instructional systems design model, the level of organizational readiness, involvement of stakeholders, the role of rewards and recognition, and appropriate metrics.
