Social capital in the classroom: a study of in-class social capital and school adjustment     

Ronan Van Rossem  Marjolijn Vermande  Beate Völker  Chris Baerveldt 《British Journal of Sociology of Education》2015,36(5):669-688

Social capital is generally considered beneficial for students’ school adjustment. This paper argues that social relationships among pupils generate social capital at both the individual and the class levels, and that each has its unique effect on pupils’ performance and well-being. The sample in this study consists of 1036 children in 60 first-grade classes in 46 Dutch elementary schools. Multilevel regression results show that a substantial proportion of the variance in school adjustment can be attributed to the class level and that both individual-level and classroom-level social capital have substantial effects on school adjustment. At the individual level, the size of one’s network is more important than its structure. At the collective level, social capital also has a ‘dark side’ because it can have negative effects on adjustment, lowering the academic performance in a class.  相似文献   

张爱玲、苏青比较研究综论     

吕纯 《齐齐哈尔师范高等专科学校学报》2015,(2)

张爱玲和苏青是同时代的作家,写作内容大抵相同,都是世俗的市民生活,但是同中有异。而且可贵的是,两位作家惺惺相惜,作品都受到广大读者的喜爱,在文坛上都有一定的地位,被称为文坛双壁。所以研究者众多,论文成果也很多,但是研究视角偏窄,真正有分量的研究成果并不多。  相似文献

Understanding the Internet banking adoption: A unified theory of acceptance and use of technology and perceived risk application     

Carolina Martins  Tiago Oliveira  Aleš Popovič 《International Journal of Information Management》2014

Understanding the main determinants of Internet banking adoption is important for banks and users; our understanding of the role of users’ perceived risk in Internet banking adoption is limited. In response, we develop a conceptual model that combines unified theory of acceptance and use of technology (UTAUT) with perceived risk to explain behaviour intention and usage behaviour of Internet banking. To test the conceptual model we collected data from Portugal (249 valid cases). Our results support some relationships of UTAUT, such as performance expectancy, effort expectancy, and social influence, and also the role of risk as a stronger predictor of intention. To explain usage behaviour of Internet banking the most important factor is behavioural intention to use Internet banking.  相似文献   

Open to suggestions: How organizations elicit suggestions through proactive and reactive attention     

Linus Dahlander  Henning Piezunka 《Research Policy》2014

This paper analyzes organizations’ attempts to entice external contributors to submit suggestions for future organizational action. While earlier work has elaborated on the advantages of leveraging the knowledge of external contributors, our findings show that organizational attempts to attract such involvement are likely to wither and die. We develop arguments about what increases the likelihood of getting suggestions from externals in the future, namely through (1) proactive attention (submitting internally developed suggestions to externals to stimulate debate) and (2) reactive attention (paying attention to suggestions from externals to signal they are being listened to), particularly when those suggestions are submitted by newcomers. Findings from an analysis of about 24,000 initiatives by organizations to involve external contributors suggest these actions are crucial for receiving suggestions from external contributors. Our results are contingent upon the stage of the initiative because organizations’ actions exert more influence in initiatives that lack a history of prior suggestions. Our work has implications for scholars of open innovation because it highlights the importance of considering failures as well successes: focusing exclusively on initiatives that reach a certain stage can lead to partial or erroneous conclusions about why some organizations engage external contributors while others fail.  相似文献   

User community vs. producer innovation development efficiency: A first empirical study     

Christoph Hienerth  Eric von Hippel  Morten Berg Jensen 《Research Policy》2014

In this paper we report upon a first empirical exploration of the relative efficiency of innovation development by product users vs. product producers. In a study of over 50 years of product innovation in the whitewater kayaking field, we find users in aggregate were approximately 3× more efficient at developing important kayaking product innovations than were producers in aggregate. We speculate that this result is driven by what we term “efficiencies of scope” in problem-solving. These can favor an aggregation of many user innovators, each spending a little, over fewer producer innovators benefitting from higher economies of scale in product development. We also note that the present study explores only one initial point on what is likely to be a complex efficiency landscape.  相似文献   

A hierarchical network-oriented analysis of user participation in misinformation spread on WhatsApp     

《Information processing & management》2022,59(1):102757

WhatsApp emerged as a major communication platform in many countries in the recent years. Despite offering only one-to-one and small group conversations, WhatsApp has been shown to enable the formation of a rich underlying network, crossing the boundaries of existing groups, and with structural properties that favor information dissemination at large. Indeed, WhatsApp has reportedly been used as a forum of misinformation campaigns with significant social, political and economic consequences in several countries.In this article, we aim at complementing recent studies on misinformation spread on WhatsApp, mostly focused on content properties and propagation dynamics, by looking into the network that connects users sharing the same piece of content. Specifically, we present a hierarchical network-oriented characterization of the users engaged in misinformation spread by focusing on three perspectives: individuals, WhatsApp groups and user communities, i.e., groupings of users who, intentionally or not, share the same content disproportionately often. By analyzing sharing and network topological properties, our study offers valuable insights into how WhatsApp users leverage the underlying network connecting different groups to gain large reach in the spread of misinformation in the platform.  相似文献

技术采纳模型（TAM）是1989年美国学者Davis在理性行为理论（TRA）的基础上,提出的一个专门用于描述用户信息技术采纳和接受行为的模型。本文以CNKI数据库为原始文献来源,对技术采纳模型的相关文献分别从发表年份、刊登期刊、作者合作度、研究领域、研究层次、研究方法、采用变量等方面进行计量分析,为今后的研究和应用奠定基础和提供参考。

Abstract：

Technology Acceptance Model （TAM） is a model proposed by Davis,an American scholar,based on the Theory of Reasoned Action （TRA） in 1989.It’ s a model used specially to describe the information technology adoption and acceptance behavior of the users.Taking the CNKI database as the original literature sources,this paper makes a statistical analysis of the related literatures of TAM from the aspects of publication year,publication journal,author cooperative degree,research field,research level,research method,and variables adopted in an attempt to lay a foundation and provide reference for future research and application.  相似文献
