A new approach to explore the knowledge transition path in the evolution of science & technology: From the biology of restriction enzymes to their application in biotechnology     

Xiaojun Hu  Ronald Rousseau 《Journal of Informetrics》2018,12(3):842-857

In this contribution, we develop a new approach to explore the process of knowledge transition from discovery-oriented science to technological fields, via applications-oriented research, including a mediator set. This trajectory is referred to as the D-A-T trajectory. It is shown how it can be constructed and measures are proposed to characterize the relational strength among different environments (discovery oriented research, applications-oriented research and patents) and the speed of evolution. Our approach is illustrated by a case study of three fundamental restriction enzymes articles. Among other results we found that 387 patents cited 124 of the 988 articles (a share of 12.55%) in the mediator set. Defining the non-patent references (NPR) transition rate as the number of citing patents divided by the number of articles in the mediator set yields a value 0.392. Our results suggest that the D-A-T path acts as a backbone and reveals important “invisible contributions” of an original scientific work during its evolution from discovery oriented research to outside academia. Our contribution provides a useful tool for bridging the existing gap in detecting the transition of knowledge between science and technology.  相似文献

试论新增专业文献建设的困境及其对策     

张怡 《渭南师范学院学报》2011,26(2):89-91,94

文献信息建设是高校教育特别是新增专业建设和发展的重要内容，也是其三大支撑性要素之一，而我国各个院校都面临着新增专业学科文献信息建设明显不足和失措的困境．这种普遍性状况源于新增专业学科文献信息建设中先天性、源头性、境遇性、制度性和主体性等一系列相互关联的因素．各院校图书馆应该坚持对策性原则，加强新增专业文献信息建设，以走出目前的困境并推进新增专业的学科发展．  相似文献   

‘It's The Catcher in the Rye… He said it was the kind of book you made your own': Finding Holden in Contemporary YA Literature     

Steven T. Bickmore  Kate Youngblood 《English in Education》2014,48(3):250-263

Published in 1951,The Catcher in the Rye encapsulated teenage angst. Some time ago David Belbin mused about the influence of Catcher on the proliferation and popularity of YA literature. Salinger's recent death has sparked a renewed interest in his work and more attention on Holden and his inheritors. This article discusses how five recent adolescent novels, with male protagonists, mirror Holden's adolescent paralysis. They exist in a liminal state between childhood and adulthood, attempting to understand the phonies around them. These protagonists help define the nature of the ‘lost’ adolescent in the current golden age of YA literature.  相似文献   

Screening for risk of low energy availability in athletic and recreationally active females in Ireland

ABSTRACT

Introduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required.  相似文献

表现主义论争：起因、内容及其思考     

张宪军 《海外英语》2015,(6)

表现主义作为德国现代主义文艺思潮，在美术、文学、电影、音乐和建筑等领域都取得了明显的成就，但在表现主义文艺思潮沉寂之后的1937—1938年间的关于这场文艺运动的论争再次将人们的视线引向表现主义，这场论争有一定的偏向性，但论争本身也使人们加深了对表现主义的理解，该文拟对这场论证的缘起和内容进行说明，并指出这场论争的意义。  相似文献
