A triangular prism model: Using activity theory to examine online learning communities

This article illustrates how a triangular prism model (TPM) could help researchers examine challenging and successful factors to sustaining online learning communities (OLCs) for preservice and inservice teachers. The TPM was constructed on a review of the literature on activity theory. The TPM is a conceptual framework that guides empirical examination of OLCs’ ongoing development and their connections within a relevant context. This article highlights the application of this framework to two online learning communities (preservice and inservice teachers) and reviews the potential of a TPM as an analytical tool.     

Preparing in-service language teachers to design and implement technology-rich curriculum

This article examines a technology-rich curriculum project that was implemented in China with in-service teachers during a three-year period. The findings suggest the need to support in-service teachers to implement new technology-rich curriculum. The findings also imply the need for curriculum designers to have a good understanding of not only their team members, but also of EFL (English as a Foreign Language) teachers in order to provide appropriate and relevant technology-rich curriculum. The authors suggest important related topics for further research, such as job-embedded professional development and professional learning communities.     

Why are we using action learning and in what contexts?

The purpose of this study was to examine the contexts in which action learning has been used and provide implications for the design of action learning programmes. We performed a content analysis of 127 articles (case studies and case reports included) published in Action Learning: Research and Practice between 2004 and 2012. In this study, we address the following research questions: (a) In what contexts has action learning been used? (b) What are the distinctive features of cases identified? (c) What are the implications for the design of action learning programmes? The results showed that the UK and European countries have most frequently used action learning, and the most dominant purposes for action learning were leadership development, organization development, and professional development. We also elaborated on design considerations and implications for action learning research and practice.     

我国构建取得时效制度的必要性

作为一项古老的民事法律制度,取得时效制度由来已久。它起源于古罗马法,并随着时代的发展,逐渐为世界大多数国家所采纳,该制度的优越性不言而喻。我国由于受苏联思想观念和立法技术的影响颇深。只采用了单一的时效制度,并未规定取得时效制度。现已颁行的《物权法》依旧没有关于该制度的规定。学界关于我国是否有必要构建该制度的争论经久不衰。但经济、道德和法律等因素决定我国有构建取得时效制度的可能性与必要性。     

论佛学对梁启超晚期史学的影响

梁启超晚年偏爱佛学,在史学研究中大量使用佛学话语来解读历史和史学,倡导史学界重视佛教和佛学,故其晚期史学思想也深受佛学理念的影响,在历史发展动力、因果律的理解及经世致用思想等方面表现出不同以往的思想倾向,体现出明显的佛学取向。佛学的影响使他更加注重历史发展主体性因素和精神作用,塑造了其晚期史学的基本风貌,并使其得以融汇佛、史,以佛家的胸怀践行史家的天职。     

我国公共保障性住房供给结构优化研究

近年来,我国住房保障制度建设取得了巨大进步,愈来愈多的居住弱势群体实现了"住有所居"梦想。然而,公共保障性住房供给结构方面暴露出了一系列问题。这些问题是否得到有效解决将在很大程度上影响到我国住房保障制度的可持续发展。为了提高保障性住房供给效率,更好地解决中低收入群体的居住问题,当前应尽快出台住房保障法律法规以规范供给结构,同时整合现有住房保障产品,建立以租赁型为主、出售型为辅的住房保障体系,实现优化供给结构的目的。     

一种高刚度六辊轧机机架刚度和模态分析

建立了一种斜楔液压压下高刚度六辊轧机和普通六辊轧机的机架有限元模型,并进行静力学分析和模态分析,结果比较显示,高刚度轧机机架的静态刚度和垂向动态刚度均高于普通轧机,为该高刚度轧机机架的设计、应用和抑制振动等提供理论依据。     

国有资产学提高实验教学质量刍议

国有资产学的跨学科属性,决定了国有资产学教学方法的多样性。现阶段国有资产学实验教学重理论验证、轻逻辑演绎,重实验形式,轻内在要求,对提升国有资产学教学质量并无显著促进作用。为提高国有资产学实验教学质量,规制国有资产学实验教学过程中出现的问题,国有资产学实验教学应实现理论探讨与实验教学的无缝衔接,强化使用具有基础性实验功能的系统动力学软件,加强实验课程教学的全程监督管理,突出强调实验教学后期的经验总结。     

8种杀菌剂对苦瓜枯萎病菌的室内毒力测定

采用生长速率测定法和分生孢子萌发抑制率法,在舍药PDA平板上和凹玻片上分别测定8种杀菌剂对苦瓜枯萎病尖孢镰刀菌的毒力作用。结果表明：20％五氯硝基苯DP对菌丝生长的抑制作用最强,EC50值为8．37mg／L,其次为40％五硝·多菌灵WP、12．5％戊唑醇WP、50％多菌灵WP和75％百菌清、聊,EC50值分别为：10．61mg／L、10．65mg／L、12．62mg／L、15．40mg／L。12．5％戊唑醇WP和对孢子萌发抑制作用最强,EC50值为3．68,20％五氯硝基苯DP、25％腈菌唑EC、40％五硝·多菌灵Ⅵ巾、50％多菌灵WP次之,EC50值分别为4．81mg／L、8．51mg／L、9．90mg／L、11．17mg／L。
