Supercomplexity and the university: Ronald Barnett and the social philosophy of Higher Education          下载免费PDF全文

Søren S. E. Bengtsen 《Higher Education Quarterly》2018,72(1):65-74

Ronald Barnett's modern classic Realizing the University in an Age of Supercomplexity (published December 1999), has had a crucial impact internationally on the field of Higher Education research and development since the book was published now nearly 20 years ago. Bridging an academic oeuvre across almost 30 years with close to 30 published volumes, Realizing the University in an Age of Supercomplexity plays an important role in the development and transformation of Barnett's social theory of Higher Education into a social philosophy of Higher Education. In the book Barnett performs an important move from a focus on knowledge and epistemology to a focus on being and ontology in relation to Higher Education practices. Barnett shifts his fundamental perspective and view on the relation between universities and the wider society from one of caution and worry to a perspective of hope and vision that fully embraces the future of Higher Education. This way, Realizing the University in an Age of Supercomplexity has not only paved the way for Barnett's own development of a social philosophy of Higher Education, but also contributed invaluably to the rise and maturing of philosophy of Higher Education as a research field in its own right.  相似文献   

图书馆科普教育现状与发展路径探究——基于25个省市88家科普教育基地调查     

徐基田 《图书情报工作》2020,64(9):35-45

[目的/意义] 图书馆肩负着实施科普教育的法定职责，拥有品种多样、内容丰富的科普文献与信息资源的图书馆，在开展科普教育方面具有得天独厚的优势。图书馆科普教育起步比较早，2005年，中国图书馆学会成立科普与阅读指导委员会；但在图书馆业界，科普教育只是零星的点缀式服务创新探索，尚未成为常态化服务项目。在依法治馆、创新发展的新时代，寻求图书馆科普教育发展路径具有较强理论和实践意义。[方法/过程] 通过互联网、微信等社交网络平台，对图书馆科普教育基地建设的状况进行调研，从基地等级、基地类型、基地数量、区域分布、有效期限以及认定依据等方面进行深入分析，并对图书馆实施科普教育提出发展路径以供选择。[结果/结论] 图书馆科普教育应坚持基地建设与科普服务相结合、阅读推广与全民科普相融合、科普与游学并举等策略，走设施、资源、服务"三位一体"的持续稳健协调发展之路。  相似文献   

汽车变速器CAE仿真与试验分析     

赖俊  梅自元 《清远职业技术学院学报》2020,(1):51-54

变速器作为汽车动力总成系统的关键部件,其功能的可靠、耐久的长短等性能直接影响到汽车的整体功能。CAE仿真与试验是变速箱性能验证的重要手段,通过结合设计阶段的CAE仿真与样件阶段的试验验证进行对比研究,能够使变速器在量产前完善设计,减少试验的样本量,从而实现缩短变速器设计周期和降低成本的目的。  相似文献   

“Wealth Makes Many Friends”: Children Expect More Giving From Resource-Rich Than Resource-Poor Individuals     

Richard E. Ahl  Yarrow Dunham 《Child development》2019,90(2):524-543

Young children show social preferences for resource-rich individuals, although few studies have explored the causes underlying such preferences. We evaluate the viability of one candidate cause: Children believe that resource wealth relates to behavior, such that they expect the resource rich to be more likely to materially benefit others (including themselves) than the resource poor. In Studies 1 and 2 (ages 4–10), American children from predominantly middle-income families (n = 94) and Indian children from lower income families (n = 30) predicted that the resource rich would be likelier to share with others than the resource poor. In Study 3, American children (n = 66) made similar predictions in an incentivized decision-making task. The possibility that children's expectations regarding giving contribute to prowealth preferences is discussed.  相似文献   

Food (in)security communication: a Journal of Applied Communication Research forum addressing current challenges and future possibilities     

Megan K. Schraedley  Hamilton Bean  Sarah E. Dempsey  Mohan J. Dutta  Kathleen P. Hunt  Sonia R. Ivancic 《Journal of Applied Communication Research》2020,48(2):166-185

ABSTRACT

This forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities.  相似文献
