Trends of infodemiology studies: a scoping review          下载免费PDF全文

Kimia Zeraatkar  Maryam Ahmadi 《Health information and libraries journal》2018,35(2):91-120

Introduction

The health care industry is rich in data and information. Web technologies, such as search engines and social media, have provided an opportunity for the management of user generated data in real time in the form of infodemiology studies. The aim of this study was to investigate infodemiology studies conducted during 2002–2016, and compare them based on developed, developing and in transition countries.

Methods

This scoping review was conducted in 2017 with the help of the PRISMA guidelines. PubMed, Scopus, Science Direct, Web of Knowledge, Google Scholar, Wiley and Springer databases were searched between the years 2002 and 2016. Finally, 56 articles were included in the review and analysed.

Results

The initial infodemiology studies pertain to the quality assessment of the hospital's websites. Most of the studies were on developed countries, based on flu, and published in the Journal of Medical Internet Research.

Conclusion

The infodemiology approach provides unmatched opportunities for the management of health data and information generated by the users. Using this potential will provide unique opportunities for the health information need assessment in real time by health librarians and thereby provide evidence based health information to the people.

A post-American world? Assessing the cognitive and attitudinal impacts of challenges to American exceptionalism     

Jason Gilmore  Charles Rowling 《The Communication Review》2018,21(1):46-65

A number of voices have emerged in U.S. political discourse questioning the legitimacy of American exceptionalism, suggesting we are in a “post-American world.” Our research examines the effects that political messages that explicitly challenge American exceptionalism can have on U.S. public opinion. Drawing upon social identity theory, we find that explicit challenges to American exceptionalism significantly impact Americans’ views toward their own nation, their willingness to denigrate foreign publics, and their broader foreign policy preferences.  相似文献   

Spatial Discovery of Linked Research Datasets and Documents at a Spatially Enabled Research Library     

Sara Lafia  Werner Kuhn 《Journal of Map & Geography Libraries》2018,14(1):21-39

Current publishing practices in academia tend to result in datasets that are difficult to discover. This is because datasets are not well-integrated across academic domains and they are often not linked to the documents that reference them. For these reasons, discovering datasets across domains can be challenging; for example, discovering archeological observations and biological specimens using the same search is not widely supported, even if both datasets share a similar spatial extent, like Mesoamerica. It is also challenging to retrieve relevant documents that reference datasets; for example, retrieving a series of field reports that reference archeological observations is typically not supported. Our work develops an extensible method for: (1) geographically integrating collections across disciplinary repositories and (2) connecting datasets to related documents. We describe a collection of spatially-referenced researcher datasets, capturing their metadata elements and encoding them as linked open data. We then leverage existing library services to formalize links from datasets to documents. The system described in this work has been deployed, resulting in an experimental open data site for the UCSB campus. Results indicate that this system can be scaled-up with support from an institutional repository in the near future.  相似文献   

The Formation of Swedish Media Studies, 1960–1980     

Mats Hyvönen  Pelle Snickars  Per Vesterlund 《Media History》2018,24(1):86-98

Around 1960, the politics of the emerging media society in Sweden tended to fixate the formative functions of mass communication. The monopoly of public service broadcast media, press subsidies and new tendencies in film policy were some of the issues around which uncertainty prevailed. New methods to provide reliable data were sought by politicians, since empirical facts were required as arguments for an updated media policy. This article examines the different ways that the field of media studies was introduced in Sweden between 1960 and 1980. We argue that Swedish academic media studies departed from, and emerged within, a rather diffuse borderland between industry, politics and academia. The formation of national media research in Sweden can partly be seen as an effect of politicians and the media industry wanting to be better informed on issues such as media influence, media ownership and the habits and composition of the media audience.  相似文献   

Gallipoli,Media and Commemorations During 2015: Select perspectives     

Chandrika Kaul 《Media History》2018,24(1):115-141

Given the iconic status assigned to Gallipoli, virtually from the outset, it was inevitable that in its centenary year, commemoration would receive enormous political and media attention. My intention is not to produce a comprehensive summary of all international media output on Gallipoli, even if that were possible within the confines of a journal article. Language barriers and problems of access have further impacted on the selection process, as well as in the coverage of even countries that have been examined (I do not speak French, German or Turkish; I also did not have access to non-English publications in India.). Nor is the article meant to be a synthesis of historiographical debate on Gallipoli, a subject which military and other experts have successfully addressed in the past as well as during the centenary (Please see reference section below for a selection of relevant books.). Rather, my more modest aim is to highlight seminal themes and offer an assessment of response, both in and by the media, especially the print media, in some of the main belligerent countries situated today in differing geo-political contexts, viz. Great Britain, Australia, India (then part of the British empire) and Turkey (then part of the Ottoman empire). Arguably, at one level, there was little in the transnational response during 2015 which attempted to shift the foundational basis for a reading of Gallipoli that has been established in the media during the intervening decades. Yet, there were some notable shifts in transnational perspectives. Perhaps after the lapse of a century, it may be possible to achieve/restore some kind of balance to our appraisal of Gallipoli in the public mind.  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
