谁在操纵BBC——公众?政府?——透视英国政府关于BBC公共广播改革的“绿皮书”

英国政府就BBC颁布的“绿皮书”(近12万字,全称为“BBC皇家管理宪章分析———一个独立于政府的强大的BBC”),由三大部分20个问题组成。它为BBC的运营做了详细的规划。本文透过BBC“绿皮书”,分析了BBC董事会分解的原因和背景,同时解答了广为人们关注的诸多问题:BBC托管真的能在未来代表付执照费者的利益吗?BBC能够履行其责任并有权利批准预算和计划吗?“绿皮书”公布之后各方的反应如何?BBC真的独立于政府吗?     

Addressing the wicked problem of behaviour in schools

Behaviour management is an influential educational cliché in Australia, Canada, England, New Zealand and US. In practice, efforts to control student conduct in schools frequently utilise a manage-and-discipline model: a misinformed but deeply rooted set of interconnected notions about how to ensure an orderly and productive classroom. Students with disabilities affecting their behavioural development or who have mental health (MH) difficulties frequently face disadvantage, suspension or exclusion as a result of the application of this model in practice. Accommodating the behavioural needs of this population and at the same time, enabling their inclusion therefore represents a significant wicked problem for education in Australia, Canada, England, New Zealand and US. Evidence-based initiatives designed to address this dilemma in the US since the late 1990s, using PBS (Positive Behaviour Support) and also SWPBS (School-Wide Positive Behaviour Support), are outlined but the conclusion is reached that these efforts do not appear to have been successful. Recommendations are made for progress in tackling this wicked problem and include: wholehearted rejection of the manage-and-discipline model by practitioners; targeted support for teachers experiencing (or at risk of experiencing) occupational burnout; and the introduction of tangible educational policy incentives intended to encourage schools to include students who might otherwise face suspension or exclusion on behavioural grounds. Finally, this article advocates radical change in attitudes by teachers towards student conduct in schools and argues that educational practice should align with insights about human behaviour arising from research in developmental psychology.

多媒体设备维护二、三事

无盘工作系统能否正常工作与网络的性能是否良好密切相关,特别是在底层的结构上,一定要保证工艺,保证质量。在日常的维护工作中要十分注意这些细节。当投影机的投影效果下降,亮度降低,对比度下降时,不仅要检查灯泡使用时限,也要检查PBS镜片的状态,以确保维护完成后获得预期的效果。     

关于上博简《孔子诗论》编联排序的几个问题

在对上博简《诗论》次序的编排中，不宜把29支简之间看作有非常严密而清晰的逻辑关系。应坚持形制优先的做法，竹简上的墨节可能是“章”而不是“篇”的隔离符号，它对判断第1支简的归属关系有重要意义，留白简的空白处原来可能没有字，可作为一个单元编联，要对竹书残缺的部分进行补字，必须根据形制来确定字数，用“句式法”和“篇名法”补字是有效的，但不能把这种方法扩大化或绝对化。

School-wide Positive Behavior Support: Addressing Behavior Problems that Impede Student Learning

The school-wide application of positive behavior support (PBS) is a prevention-oriented approach to student discipline that is characterized by its focus on defining and teaching behavioral expectations, rewarding appropriate behaviors, continual evaluation of its effectiveness, and the integration of supports for individuals, groups, the school as a whole, and school/family/community partnerships. Although school-wide PBS has been implemented in hundreds of schools thus far, many professionals in education and psychology remain, for the most part, unfamiliar with this proactive alternative for increasing positive student behavior. This article reviews the foundations and core components of school-wide PBS, provides a case example of the implementation and preliminary evaluation of school-wide PBS in an urban middle school, and summarizes critical issues and future research directions in this area of considerable importance to professionals in educational psychology and related fields.     

Performance measurement of broadband, wide-angle polarizing beam splitter

INTRODUCTION A polarizing beam splitter (PBS) cube is an op- tical element used in projection display systems where light must be spatially separated into or- thogonal linear polarizations. PBS is a key component in any liquid crystal projectors, whether they are transmitting or reflective. In reflective mode liquid crystal light valve projector, PBS is often used as both polarizer and analyzer. PBS transmits p-polarized light and reflects s-polarized light (You et al., 2005). The im…
