Can social integration in schools be mandated: Evidence from the Right to Education Act in India     

《International Journal of Educational Development》2020

Although Affirmative Action policies have been enforced in many countries, their consequences are highly understudied, especially in the context of developing economies. Section 12(1)(c) of the Right to Education (RTE) Act enforced in 2009 is the first attempt to introduce affirmative action in primary schools in India. The act requires all private schools to reserve at least twenty five percent seats for children from economically weaker sections. To understand the effect of the act on i) social integration and ii) academic outcomes, we asked 1500 children (grades one to three) from four schools to answer friendship surveys and short tests in Mathematics and English. The schools in our sample vary considerably in constitution and were intentionally chosen to understand the impact of the act in different school settings. The friendship surveys show strong homophily i.e. non-RTE students cite other non-RTE students as friends, while RTE students chose to be friends primarily with other RTE students. Trends in test scores reveal that students admitted under the RTE quota score significantly lower than non-RTE students. However, RTE students who have a higher share of non-RTE friends have better test scores, suggesting that affirmative action may have a positive influence on learning outcomes for RTE children. Further we note that commitment from the school authorities and systematic monitoring and evaluation of the implementation of the act will go a long way in bringing out some of the benefits that this act was designed to achieve. Our findings have important policy implications with respect to ensuring proper implementation of the Section12(1)(c) of the RTE act in schools across the country.  相似文献   

Identifying the combinations of motivations and emotions for creating satisfied users in SNSs: An fsQCA approach     

《International Journal of Information Management》2020

Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empirically study with 582 SNSs users, we present eight combinations (configurations) of motivations and emotions that lead to high satisfaction, which highlight the role of high convenience, followed by entertainment and information motivations in being satisfied with SNSs. High satisfaction can be achieved both when positive and negative emotions are high and low, depending on how they combine users’ motivations. None of the factors are indispensable to explain high satisfaction on their own, instead they are insufficient but necessary parts of the causal combinations that explain high satisfaction. This study contributes in SNSs literature by extending current knowledge on how motivations and emotions combine to increase satisfaction, and by identifying specific patterns of users for whom these factors are important and influence greatly their satisfaction.  相似文献

研发费用加计扣除是否提升了企业创新能力?——创新链全视角          下载免费PDF全文

冯泽  陈凯华  戴小勇 《科研管理》2019,40(10):73-86

现有关税收优惠政策对企业创新活动影响的文献缺乏从整个创新链的全角度揭示税收优惠政策是否真正提高企业创新能力的探索。基于中关村科技型企业数据，本文选取税收优惠政策中典型的政策工具“研发费用加计扣除”作为研究对象，有别于已有主要从“投入”视角关注研发费用加计扣除引导作用的研究，从“投入-产出-收益”的创新链全视角，将创新过程分为技术研发阶段与技术转化阶段，以揭示研发费用加计扣除政策是否真的提升了企业创新能力。基于PSM-DID方法的实证研究结果发现：在投入端，研发费用加计扣除政策显著提高了企业的研发投入规模与强度；在产出端，研发费用加计扣除政策仅促进了研发产出规模的提升，而对于产出强度则无显著影响；在收益端，研发费用加计扣除对收益规模与强度同样有显著的促进作用。本文的发现肯定了我国研发费用加计扣除政策的引导作用，以及其在企业创新能力提升中发挥的积极作用。本文的研究思路为揭示政府创新激励政策的效果提供了新视角，研究发现为从创新链与企业创新能力的角度思考和改善政府研发税收优惠政策的管理和实施提供了新证据。  相似文献   

Teaching for understanding and school sport: a study in an intercultural context and situation of social risk / Enseñanza para la comprensión y deporte escolar: un estudio en contexto intercultural y situación de riesgo social     

Bastian Carter-Thuillier  Víctor López-Pastor  Francisco Gallardo-Fuentes 《Infancia y Aprendizaje》2018,41(3):491-535

This study analyses the integration of Mapuche-Huilliche students who participate in a school sport programme based on the teaching for understanding model in a situation of social risk. In this context, 41 students (aged nine to 12) participate, 24 of whom are from the aforementioned ethnic group. To collect data, participant observation was conducted for eight months and group and individual interviews were held. The results show that the Mapuche-Huilliche students recognize themselves as members of the same collective when participating in games associated with their ethnic group. Their main motives for participating in school sport are the teaching approach and the acquisition of social capital. Cooperative learning activities are shown to foster positive interactions with non-Mapuche students.  相似文献   

The Buddhist Institute at Phnom Penh,the International Council of Women,and the Rome International Institute for Educational Cinematography: intersections of internationalism and imperialism, 1931–1934     

Joyce Goodman 《History of education》2018,47(3):415-431

This article explores the intersection of aspects of imperialism and internationalism in discussion of cinematography at the League of Nations, at the International Council of Women (ICW), and as they played out in the imperial, national and local flows around educational cinematography in the work of Suzanne Karpelès at the Institute of Buddhist Studies in Phnom Penh, Cambodia. It focuses on the 1931 ICW cinematograph conference organised by Laura Dreyfus-Barney at the League’s Rome International Institute for Educational Cinematography (IIEC) and on the IIEC’s 1934 cinematography congress, when Dreyfus-Barney fed Karpelès’ ideas about educational film into the congress. The article looks at the notion of rapprochement (of nations) within internationalism as this became articulated at both the League and the ICW with notions about mentalities within imperialism. It also traces the intersection of rapprochement and mentalities in Karpelès’ promotion of educational cinematography from her base in Phnom Penh. The article concludes that various elements around the cinematic at the League, the ICW and at Phnom Penh illustrate articulations of internationalism in the domains of nationalism and imperialism as well as articulations of the national and imperial in the domain of the international.  相似文献   

论“新校园足球”的顶层设计(5)——以“一校一品”和“1+X”为灵魂的新校园足球课程教学模式     

钟勇  毛振明  潘建芬 《武汉体育学院学报》2018,52(1):19-23

当前的校园足球面临着校园足球发展与"全体学生的体育发展"的矛盾、校园足球如何与其他运动项目共同发展的问题、校园足球的教学、训练、比赛等工作的协调发展等较为突出的问题。国务院办公厅文件中提出的"一校一品"、"一校多品"的体育课程教学改革在时间上形成交叉共振，但两者具体是怎样的关系缺乏讨论。"一校一品"应是学校明确确定一个最有特色的体育项目作为全体学生学习的主项，各个年级均以其为主要教学内容，技战术难度随年级递增，每个年级用1/2-2/3的时间进行该主项的教学，其他时间用于其他运动项目的"简学"的课程教学模式；而"一校多品"体育课程教学应是：在年级内打破班级上体育课为形式的选择性专项化体育教学模式。以"一校一品"和"一校多品"为核心的新足球课程教学模式的构建可以较好地解决当前校园足球的基本问题。建议校园足球的理论研究应结合"一校一品""一校多品"的课程改革趋势与要求积极进行新校园足球的课程教学模式的研究与探索，各校园足球特色学校关注并积极探索新的体育课程教学模式。  相似文献   

Combined state and parameter estimation for a bilinear state space system with moving average noise     

Xiao Zhang  Ling Xu  Feng Ding  Tasawar Hayat 《Journal of The Franklin Institute》2018,355(6):3079-3103

This paper considers the identification problem of bilinear systems with measurement noise in the form of the moving average model. In particular, we present an interactive estimation algorithm for unmeasurable states and parameters based on the hierarchical identification principle. For unknown states, we formulate a novel bilinear state observer from input-output measurements using the Kalman filter. Then a bilinear state observer based multi-innovation extended stochastic gradient (BSO-MI-ESG) algorithm is proposed to estimate the unknown system parameters. A linear filter is utilized to improve the parameter estimation accuracy and a filtering based BSO-MI-ESG algorithm is presented using the data filtering technique. In the numerical example, we illustrate the effectiveness of the proposed identification methods.  相似文献
