有利于生态环境的绿色技术创新在可持续发展战略中居有核心地位，而传统的单一制造商创新源观点已经大大束缚了创新管理的视野，十分不利于推动我国的绿色技术创新。故本文从创新功能源入手，在实证调研的基础上分别研究了我国各类绿色技术创新功能源的分布以及功能源分布差异的经济机理，并给出了对我国当前绿色技术创新管理与政策设计的启示。  相似文献   

The effects of function-based communication intervention for a student with emotional disturbance in a general education setting     

Celal Perihan  Ali Bicer 《Journal of Research in Special Educational Needs》2021,21(2):63-72

Research has shown that most children with emotional disturbance (ED) are struggling to use communication skills and they may tend to use inappropriate behaviours as a form of communication to disclose their needs. A function-based communication intervention might be an effective approach to decrease inappropriate behaviours of children with ED. The purpose of this single-case multiple baseline reversal design (ABAB) study was to examine the effectiveness of the function-based communication intervention for on-task and disruptive behaviours of an 8-year-old student with ED. Functional behavioural assessment (FBA) was conducted and based on the findings of FBA, a colour-coded communication system, was implemented during reading and math classes. The findings indicated that function-based communication intervention was effective in increasing on-task as well as decreasing disruptive behaviours. Furthermore, the function-based communication intervention improved communication between the teacher and the student that resulted in decreasing disruptive behaviours in a general classroom setting. The generalisability of the findings due to the limited number of participants was an important limitation for this study. Future directions, as well as implications for practices, are discussed.  相似文献

A taste of functional programming — 2     

Madhavan Mukund 《Resonance》2007,12(9):40-63

Functional programming has its roots in Alonzo Church’s lambda calculus. In the first part¹ of this article, we explored some basic notions of functional programming using the language Haskell. We now examine some more advanced concepts, including polymorphism, infinite data types and computations, and user-defined data types. Madhavan Mukund has been on the Computer Science faculty at Chennai Mathematical Institute since 1992, where he is currently Professor. His research interests are primarily in formal methods for specifying and verifying computing systems. He is the Secretary of the Indian Association for Research in Computing Science (IARCS) and the National Coordinator of the Indian Computing Olympiad.  相似文献   

Differences of math anxiety groups based on two measurements,MASS and EEG     

Sang S. Choi-Koh  Byeong G. Ryoo 《教育心理学》2019,39(5):659-677

This article investigated how mathematic anxiety (MA) of Korean middle school students could be reduced by comparing analytically their cognitive neuroscience and questionnaire results. We developed a three-hour Complex Treatment Program (CTP) on quadratic functions for the study. In the summer of 2016, we collected data of the pre and post MA questionnaires by Mathematics Anxiety Scale for Students (MASS), the percent of correct answers (PCA) and reaction time (RT) by E-prime program, and also brain-imaging data of the event related potentials (ERP) by Electroencephalograph (EEG) using computer-based functional F-G model. The result indicated the CTP to be effective with the group with higher math anxiety and the group with higher achievement respectively. The MASS result was verified with the better performance of PCA on type G, which was measured by E-prime program. Some interesting patterns were revealed on brain-imaging data by EEG, indicating more brain activities with the MA groups.  相似文献   

Functional reading difficulties in Denmark     

Carsten Elbro  Susan Møller  Elisabeth Munk Nielsen 《Reading and writing》1995,7(3):257-276

In this first Danish study of adult reading skills, 1124 adults between 18 and 67 years of age participated in an interview about reading habits and skills, and 445 were tested individually at home using six common texts. Great care was taken to ascertain that subjects were representative of the whole adult population and that the texts covered most types of everyday reading. Three percent of the participants were found to have severe functional reading difficulties and a further 9 percent to have moderate difficulties. Regression analyses found several unique predictors of reading difficulties: age (adults over 45 years reading more poorly than younger adults), limited basic education, no vocational training nor higher education, and a small amount of reading needed at work. The rate of poor readers was about four times higher among persons with low income than among others. Men and women read equally well although men tended to rate themselves lower as readers than women did. Methodological issues and some educational implications are discussed.  相似文献   

Examining the effect of positive behaviour support on academic achievement of students with disabilities

Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.

自布拉格学派提出音系学中有标记和无标记的对立以来,标记性的概念已被延伸应用于语言学研究的其他方面。系统功能语言学对标记性问题有其独特的研究视角。文章总结韩礼德功能语法中对小句主位结构以及信息结构的标记性现象的探讨,并进一步分析系统功能语言学标记性研究的盖然率视角在解释语言系统的性质、研究语言使用的特征和探讨儿童的语言发展等方面的指导意义。  相似文献
