ABSTRACTLight sensitive objects will fade on display. Collection managers and curators face the dilemma whether to spread fading over several similar objects or sacrifice one. This paper describes an experiment in which participants were asked how they would want to pass on a collection of seventeenth century hand-coloured maps to coming generations. Results show that while colour changes are hardly visible, both public and professionals do not perceive them as damage and prefer to spread fading. Once fading becomes clearly visible in all maps, the preference shifts to sacrificing one map. The tipping point lies around five just noticeable changes. This information can be used when selecting objects for exhibition. The outcome also implies it would be prudent to assess the degree of fading of much exhibited objects and consider whether and when to choose for a sacrifice strategy. 相似文献

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

As one of the largest active academic social networking sites, ResearchGate (RG) has been utilized by scholars to share publications, seek collaborators, communicate work in progress, and build scholarly reputation. This study collects data from RG users from 61 U.S. research universities at different research activity levels, as categorized by the Carnegie Classification of Institutions of Higher Education, to examine the impact of institutional differences on RG reputational metrics. The results confirm that RG is a research-oriented academic social networking site that closely and realistically mirrors the research activity level of institutions. With an increase in the research activity level of a university, its affiliated RG users tend to have higher RG scores, more publications and citations, and more profile views and followers, while the average number of reads of their publications and followees tend to be lower and fluctuant. In addition, RG users primarily follow others from institutions of a higher research activity level, forming virtual social networks centered around esteemed institutions. The study suggests academic social networks can serve as indicators in evaluation of research activities among research institutions, and such sites can be helpful and credible for acquiring resources, keeping informed about research, and promoting academic influence. 相似文献

量化评价是基于自然科学主义观点对学生学业开展评价,它将学生作为统一的整体忽略了个体之间的差异,而基于人文主义的质性评价则注重学生之间的个体差异。质性评价为职业教育中的学业评价提供了另一种好思路,值得研究和推广。 相似文献

我国陪审制在我国遭遇了尴尬局面,陪审制是我国司法改革的一个重要方面,为了充分实现社会主义的司法公正,该制度在我国就有存在的必要性。作者首先阐述了我国陪审制的历史沿革,并分析其立法和司法上存在的缺陷。在立法上,该制度没有宪法和相关的法律依据;在司法上,陪而不审的现象严重。在此基础上,作者对重塑我国陪审制的对策进行了思考,提出了重塑我国陪审制度的方案。 相似文献

为培养“宽专业、厚基础、能力强、素质高”的新型人才,传统的实验教学模式是不能很好地培养学生的创新精神和实践能力的。针对学生对一些纯粹的验证性实验不感兴趣,实验能力得不到提高的现象,笔者在多年的实验教学中,不断总结教学经验,在不影响实验效果的前提下,有意识设置实验障碍,以提高学生分析问题、解决问题的能力。 相似文献
