The impact of digital technology on archival science     

Luciana Duranti 《Archival Science》2001,1(1):39-55

Archival science is to be regarded as a system. The properties of that system can be investigated and integrated. The methodology to do so has been tested in two research projects which are presented in this article as examples of the way in which the view of archival science as a system supports the development of new knowledge and as a demonstration of the stability of archival theory. This article presupposes that the archival discipline is also a “science”. Many have argued against the idea on the basis of a common perception that a science is a type of study entirely objective by virtue of the rigorous manner in which it is carried out and the restricted range of topics to which it applies. In fact, the activity of science is based upon a complex framework of assumptions that make it possible for the landscape of the scientific endeavour to be redrawn over time, and, while striving towards objectivity, considers it to be an unattainable ideal.  相似文献   

对新规则下直拍进攻型打法发展趋势的研究     

赵霞  苏丕仁  张浩 《北京体育大学学报》2006,29(1):122-124

直拍进攻型打法曾经是我国乒坛的主流打法,由于缺乏创新,在近10多年一直不太景气.但是,直拍进攻型打法有其特定的优势,具有很强的抗争能力,只要创新技术、加强实力,就能登上世界乒坛的最高峰;诚然,它自身的确也存在着很多问题,加上11分赛制和无遮挡发球的实行,必定会给这种打法带来一些影响(正负双方面).因此,在新形势下对直拍进攻型打法进行进一步的深入剖析和探讨,成为我国乒坛亟待解决的课题.通过对世界优秀男子直拍进攻型打法选手的技战术进行统计与分析,并走访乒乓界权威人士和有关专家,对新规则带来的一些问题和该打法今后的发展趋势进行深入分析与探讨,为进一步提高我国直拍进攻型打法的技术水平提供科学理论和参考依据.  相似文献

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   

论阅读教学中“教”“学”主体的转变     

黄朝霞 《湖南第一师范学报》2011,11(6):43-47

在应试教育的大背景下，阅读教学已经异化为应试教学，沦落为应试教育的手段。阅读教学要做到优质高效，并对整个小学语文教学起到重要的拉动作用，必须实现由“教”到“学”的主体转变，即课堂教学要由从以教师“教”为中心转变到以学生“学”为中心。只有经历这样的转变，阅读教学才能实现质的跨越。  相似文献
