Worn Grooves     

Elodie A. Roy 《Media History》2018,24(1):26-45

Drawing from visual, material and written archival sources, this article critically explores some of the functions, uses and perceived values of recorded sound during the First World War and in its aftermath. An instrument of communication as well as commemoration, the gramophone helped bridge geographical (and, in some cases, cultural) distances between the home front and the rear, providing civilians with the fleeting illusion of presence, proximity, or even sentimental communion with the front. The article analyses (a) the affective and connective, but also propagandist, values of commercial wartime recordings as they circulated between the home and the front, (b) the popular notion of gramophones as regulatory instruments of civilisation, (c) the commemorative exploitations of recorded sound in the interwar period. The article focuses on the British experience, contrasting it with examples drawn from French and German experiences.  相似文献   

Is There a Future for Journalism?     

Guy Berger 《Journalism Practice》2018,12(8):939-953

A functionalist perspective on the future of journalism would posit that because human society needs journalism, we will find ways to support this communications practice. Yet such a perspective, however consoling, assumes a teleology that is far from guaranteed. What will happen is far from easy to predict; nevertheless, this paper pinpoints several key issues that impact on the future of journalism. It also advances some general propositions and a broad periodisation around UNESCO’s historical role in relation to these issues. The analysis gives particular attention to political and economic matters, the safety of journalists and internet governance. Each of these dimensions entails existential threats to journalism, but some opportunities are also noted. Four paradoxes are also identified, with tensions that may lead to change in one direction or another.  相似文献   

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers     

Zhigang Hu  Wencan Tian  Shenmeng Xu  Chunbo Zhang  Xianwen Wang 《Journal of Informetrics》2018,12(4):1133-1145

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.  相似文献   

美国科技博物馆展览开发中公众参与的研究及启示          下载免费PDF全文

郭佳雯 《自然科学博物馆研究》2018,(1):93-100

展览开发是博物馆展览的基础问题,随着公众参与逐渐被提上研究议程,也促使我们去思考展览开发过程中如何引入公众参与。美国的科技博物馆展览开发已经建立了较为完善的公众参与体系:明确的参与者角色、系统的参与理念和阶段式的参与行为,已经获得了普遍的应用。借鉴美国博物馆的经验,我国博物馆展览的开发,应在构建展览评估体系的基础上,进一步了解和认识公众,拓展公众参与的方式,并不断寻求公众的声音。  相似文献
