ABSTRACTEmploying a number of different standalone programs is a prevalent approach among communication scholars who use computational methods to analyze media content. For instance, a researcher might use a specific program or a paid service to scrape some content from the Web, then use another program to process the resulting data, and finally conduct statistical analysis or produce some visualizations in yet another program. This makes it hard to build reproducible workflows, and even harder to build on the work of earlier studies. To improve this situation, we propose and discuss four criteria that a framework for automated content analysis should fulfill: scalability, free and open source, adaptability, and accessibility via multiple interfaces. We also describe how to put these considerations into practice, discuss their feasibility, and point toward future developments. 相似文献

This article is principally concerned with how and why these 2 types of radio news developed. It discusses the culture, ethos and practices of the 2 services and, in particular, if and how each was influenced by the other. Much of the article is concerned about how the new commercial stations developed practices and styles that were consciously different from, and in some cases in direct opposition to, those at the BBC, both nationally and locally. The article argues that it was the BBC which adopted and integrated commercial radio’s style and practices, rather than, as is often supposed, the other way around. 相似文献

This paper considers the changing role of universities in the UK as they respond to an engagement agenda that stipulates a more immersive and visible interaction between academics and the public. It constitutes a survey of attitudes to public engagement in a selection of UK universities drawing on interviews with senior academics with managerial responsibility at the end of 2009. The results of this study reflect a mood of indecision and anxiety among respondents towards a public engagement agenda seen to influence the contours of their professional identities and working lives. The study situates academic accounts that contest the legitimacy of public engagement as a core academic activity and the role of academics in communicating with public groups. Moreover, it reveals a lack of agreement and consistency in the conceptualisation and application of public engagement in higher education contexts, certainly beyond an emergent discourse of research impact. 相似文献

The United Kingdom's Department for Education has recently changed the nature of the AS‐level examinations normally taken by students aspiring to enter higher education degree courses one year into their post‐compulsory education. In the face of protests from universities and other institutions that this would both harm students’ progression towards the A‐level qualifications, on which entry to English universities is normally based, and make it difficult for universities determining which of their applicants were best placed to benefit from their degree courses, the Department conducted research which it claimed showed that degree outcome could be predicted as well from the results of GCSE examinations taken one year before AS‐levels as from AS‐levels themselves. This paper critiques those analyses and their conclusions showing, through a re‐analysis and extended interpretation of the Department's data, that AS‐levels provide a more reliable predictor of degree performance in 2011 than GCSEs and that many students who performed better at AS‐level than at GCSE gained a place, and performed well, at a university with high entrance standards. 相似文献
