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

Physical maltreatment of children with autism in Henan province in China: A cross-sectional study     

《Child abuse & neglect》2015

The aim of this study was to investigate the frequency of child physical maltreatment (CPM) in children with autism aged 2–5 years in Henan province (China), and to explore the risk factors for severe CPM in these children. This cross-sectional study was performed at the Psychology Clinic of the Third Affiliated Hospital of Zhengzhou University between September 2012 and September 2013 with 180 parents of children with autism. Children and parents had no history of any cognitive therapy. The childhood autism rating scale (CARS) was used to evaluate the severity of autism in children. Data on parental CPM during the past 3 months were collected from parental self-reporting. Logistic regression was used to investigate the risk factors of severe CPM. CPM was self-reported by 88% of the parents of children with autism. One hundred and fifty four of these cases were in the minor CPM group (86%) and 64 in the severe CPM group (36%). Most cases of severe CPM were unlikely to have caused injury. Univariate analyses showed that child's age (p = .018), age started to speak (p = .043) and CARS score (p = .048) were associated with severe CPM. Child's age (p = .011) and CARS score (p = .041) were independently associated with severe CPM. The risk of severe CPM increased with age and CARS score. Our findings showed that CPM is widespread in families of children with autism in Central China and more knowledge should be provided to parents of children with autism, particularly in cases of severe autism (those with high CARS scores).  相似文献

幼儿独立性是幼儿自我发展的内在动力,是个性品质的基础和关键。3-6岁是幼儿自主性、独立性迅速发展的时期,而幼儿园是培养幼儿独立性的重要场所。幼儿独立性对幼儿未来的发展有着重要的影响。幼儿园的环境分为精神环境和物质环境两种,因此要从这两个环境中培养和促进幼儿独立性的发展。  相似文献   

Being bullied at school as a child,worse health as an adult? Evidence from China     

《International Journal of Educational Development》2021

This paper examines the long-run relationship between school bullying exposure and later adult health using a nationally representative household survey data from China. Our results show that victims are more likely to have low self-reported health, chronic diseases, physical functional limitations, and mental health problems even after several decades. The negative health consequences are more concentrated on the disadvantaged who come from low-income households or lack family support. The main findings are also consistent with qualitative evidence of our online survey.  相似文献

孙国秀  姜华  王志鹏 《山东商业职业技术学院学报》2011,11(2):28-30

大学生心理健康是政府关心、学校担心、家长揪心的一个非常重要的问题。现在刚入学的大学生绝大部分是90后,由于他们生活、成长的家庭、社会、教育环境不同,与以往大学生存在一些差异,必须引起我们教育工作者的重视和思考。  相似文献   

物流系统对环境扰动的机理及相互间的影响探析     

唐玉斌 《襄樊职业技术学院学报》2006,5(5):26-29

作为一项系统工程，物流系统对环境的扰动主要体现在包装、运输、储存保管、装卸搬运、流通加工、配送以及物流信息等方面。扰动的关键原因在于现实中粗放的物流模式、不合理的物流规划、物流标准化的缺乏等因素的影响。现实生活中，环境系统及其环境问题也有可能通过经济系统和法律体系等途径来制约和影响着物流系统的有序运作。  相似文献   

网络服务提供者的著作权间接侵权责任探析     

黄萱 《北京工业职业技术学院学报》2019,18(3):123-126

随着互联网的发展,信息资源得以迅捷、广泛传播的同时,网络领域的著作权侵权纠纷也随之增多。这些纠纷的产生大多与网络服务提供者有关,由其承担相应责任亦是必然。分析网络服务提供者间接侵权责任法律规制的不足,如相关立法体系不完善、责任承担的主体不明确、过错的认定不清、责任承担方式模糊,提出健全相关立法体系、明确责任承担的主体、明确过错认定准则、梳理责任承担方式等建议,从而更好维护著作权人的利益。  相似文献   

从《木兰诗》看木兰形象的文化内涵     

赵晓洁  蒙丽静 《雁北师范学院学报》2007,23(1):68-70

《木兰诗》是南北朝时期的代表作,它将木兰这个女子形象置于战争的环境中,置于个人、家庭和国家利益的矛盾交织中来展现其性格以及这种性格所包含的文化内涵。北魏的战争环境所导致的经济破坏、人口男女比例失调是《木兰诗》产生的社会背景;北方诸民族的尚武粗犷的民风民俗是《木兰诗》产生的文化环境;"木兰无长兄的实际情况导致了木兰具体的出征行为。然而,当时的人们并没有认识到木兰形象所可能包含的新的人生价值观,最终将其纳入了中国传统文化的行为规范之中。  相似文献
