关于科技学术期刊撤稿流程规范化建设的建议

撤稿是为了纠正错误,净化学术环境.虽然国内外的出版机构也制定了相应的撤稿流程指南,但国内科技学术期刊并未严格按照指南进行撤稿,各大数据库的撤稿流程也各不相同,因此学术期刊需进一步提高撤稿意识,规范撤稿流程.本文通过解读国内外撤稿指南,分析国内学会和编辑部具体撤稿措施,梳理国内知名文献数据库的撤稿流程,提出关于完善学术期刊撤稿流程规范化建设的措施,供国内期刊编辑参考.     

Which notion of implication is the right one? From logical considerations to a didactic perspective

Implication is at the very heart of mathematical reasoning. As many authors have shown, pupils and students experience serious difficulties in using it in a suitable manner. In this paper, we support the thesis that these difficulties are closely related with the complexity of this notion. In order to study this complexity,we refer to Tarski's semantic truth theory,which contributes to clarifying the different aspects of implication: propositional connective, logically valid conditional, generalized conditional,inference rules. We will show that for this purpose, it is necessary to extend the classical definition of implication as a relation between propositions to a relation between open sentences with at least one free variable. This permits to become aware of the fact that, in some cases, the truth-value of a given mathematical statement is not constrained by the situation, contrary to the common standpoint that, in mathematics, a statement is either true or false. In the present paper, the didactic relevance of this theoretical stance will be illustrated by an analysis of two problematic situations and the presentation of some experimental results from our research on first-year university students' understanding of implication. This revised version was published online in August 2006 with corrections to the Cover Date.     

大学何以要倡导和守护理想主义

大学的理想主义是大学对客观世界、社会生活以及大学自身寄予的美好期望所持有的观念体系,亦是大学对自身使命、责任、目标和操守所持有的一种既符合大学规律又有崇高要求的价值认定和信念追求,更是大学之为大学所必须固守、薪火相传并不受外界干扰的精神向往和文化灵魂。大学本身就是充满理想主义的人才培养和探求学问的场所,理想主义是大学不可或缺的对人具有深刻影响的文化精神,但不少大学已经呈现出与大学崇真、向善、求美之宗旨、之属性相悖的过度功利和势利。倡导和守护理想主义,其意义在于为大学的办学和发展及大学的教育者和被教育者提供一种美好的、纯洁的、积极的、向上的参照和追求。

On the necessary co-existence of special and inclusive education

ABSTRACT

While many distinctions between ‘special’ and ‘inclusive’ education have been made and continue to be forcefully debated, the two concepts remain strongly evident in policy and practice in many countries. This paper discusses the interrelated history of these concepts. It explores how conceptualisations of them have changed since Salamanca and reflects on whether inclusive education has, can or should replace special education. It considers the extent to which ‘special’ and ‘inclusive’ education are understood as the same or different today. The paper argues for a clear a distinction to be made between how special educators can work in support of inclusive education and the task of inclusive education which addresses the barriers to participation faced by members of marginalised groups.     

大学理想和理念漫谈

大学理想和理念体现的是大学发展的内在逻辑,是关于大学发展规律的总结和概括,是体现大学追求的一种文化,是大学的品位和精神。大学理想和理念是对大学宗旨和使命的认识,大学理想和理念是对“大学是什么”的一种表达,它规定了大学发展的路径和方向。随着社会的发展,大学在变,从而引发了大学理想和理念与现实的矛盾冲突。在新的时空背景下解读或重构大学理想和理念,必须考虑使“经典”与“现代”之间保持适当的张力。

提高执政能力是基层党组织建设的核心

基层党组织建设是党的建设新的伟大工程的基础,提高基层党组织的执政能力是加强党的执政能力建设的基础。全面提高基层党组织的执政能力,始终是基层党组织建设的核心任务,也是深入贯彻落实科学发展观、保持和发展党的先进性、加强基层党组织建设的现实需要。因此,我们必须坚持用科学发展观来指导基层党组织建设工作,不断提高执政能力。     

大道至简，追求“有魂”—论中小学校长的教育哲学追求与办学实践

校长的教育哲学追求是校长关于学校教育的系统认识和理性思索,是对学校教育的终极价值思考,是如何办好学校教育的一套价值理念和信仰,它包括对学校使命、学校愿景和育人目标的质的规定性。作者以上海市浦东新区周浦镇育才学校的办学实践为个案,具体阐明了什么是校长的教育哲学追求、校长的教育哲学追求的价值以及建立在教育哲学基础上的“午膳教育”办学实践。
