The development and initial validation of a questionnaire of inclusive teachers’ competency for meeting special educational needs in regular classrooms in China

The aim of this study was to develop and validate an instrument of inclusive teachers’ competencies for teaching students with special educational needs in China. Data were obtained from a preliminary and large-scale investigation in Beijing. The primary analyses included exploratory factor analysis and confirmatory factor analysis. The findings indicated that Chinese inclusive teachers’ competency is underpinned by four factors: teaching and instruction; communication and cooperation; attitudes and beliefs; and reflection and development. The four-factor model was obtained with satisfactory reliability and validity. The validated questionnaire generated a theoretical understanding of inclusive education teachers’ competency in China. In addition, the findings of the study provided knowledge that will allow for the development of professional standards and teacher education programmes for inclusive education.

新社会阶层的崛起与统战工作

改革开放以来,随着经济体制的转轨,社会结构的转型,产业结构的调整,中国社会阶层结构发生了新的变化.除传统的工人阶级、农民阶级和知识分子阶层外,新社会阶层正在逐步崛起和壮大,其影响力与日俱增,在各方面深刻影响着现行社会.在构建和谐社会的新时期,如何抓住这个机遇,迎接其带来的挑战,做好统战工作,就成为现代化建设的题中之义.实际上,只有依靠包括新社会阶层在内的统一战线,才能进一步扩大党的群众基础和执政基础,才能保持社会稳定与和谐,才能实现中华民族的伟大复兴.     

初中物理教学中的最值问题

最值问题是初中物理教学中常见的 ,也是学生难以掌握的问题 ,在近几年的中考和竞赛试题中也屡见不鲜。在教学上如果能适当地研究些简单的最值问题 ,让学生尽早了解这类问题的分析方法 ,这对加深理解物理知识和培养学生的思维能力都是有益的。下面举几例说明。〔例 1〕在爆破中 ,引火线的燃烧速度是 0 8厘米 /秒 ,人跑的速度是 5米 /秒 ,若引火线的长度是40厘米 ,点燃后爆炸 ,人最多能跑出多远 ?若人至少离爆破点 30 0米处 ,才能保证安全 ,那么引火线的最短长度应是多少 ?解析 :引火线燃烧 ,人跑离现场 ,两个过程在同一时间内完成。(1 )ｔ=…

Optimal restructuring strategies under various dynamic factors

Corporate restructuring was identified as a new industrial force that has great impact on economic values and that therefore has become central in daily financial decision making. This article investigates the optimal restructuring strategies under different dynamic factors and their numerous impacts on firm value. The concept of quasi-leverage is introduced and valuation models are built for corporate debt and equity under imperfect market conditions. The model＇s input variables include the quasi-leverage and other firm-specific parameters, the output variables include multiple corporate security values. The restructuring cost is formulated in the form of exponential function, which allows us to observe the sensitivity of the variation in security values. The unified model and its analytical solution developed in this research allow us to examine the continuous changes of security values by dynamically changing the coupon rates, riskless interest rate, bankruptcy cost, quasi-leverage, personal tax rate, corporate taxes rate, transaction cost, firm risk, etc., so that the solutions provide useful guidance for financing and restructuring decisions.
