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 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

Libraries have been the key to preserving culture and historic legacy for centuries. One such treasure cataloged in The Pennsylvania State University (Penn State) Libraries is a collection of over 33,000 Sanborn? Fire Insurance Maps. Originally kept safe in metal drawers, the library has embarked on a journey to digitize this abundance of information, combine it with other media such as photographs, and make it accessible through a web interface. Inspired by these efforts, we accessed this information and took it to the next level. Using state of the art 3D modeling and immersive technologies, we created a historic 3D model and immersive experiences of Penn State, exemplarily for the 1922 campus. The resulting experiences can be accessed through the web but also through head mounted displays (HMDs) and mobile phones in combination with VR viewers such as the Google Cardboard. Additionally, they can be used anywhere in the world or on the campus itself as a way to enable remote and in situ experiences and learning. Immersive experiences let us connect to the past, the present and the future, and as such offer value to digital cultural heritage efforts.  相似文献

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

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

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

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

This paper outlines a history of the union organizing of the American Newspaper Guild at Thomson Newspapers’ Peterborough Examiner in Canada from 1968 to 1969. It examines the communication tools that union members used to facilitate this labor organizing and “bite back” at the profitable Thomson chain. Peterborough newsworkers went on strike from November 1968 to April 1969 over union recognition. During the strike, the union members built an unprecedented alliance with Ontario university students, collaboratively launching a strike newspaper called the Peterborough Free Press. Expanding on the concept of temporary labor convergence, this paper considers how strike newspapers can be seen as a form of alternative journalism that newsworkers use as a campaigning tool to communicate their struggles to the public and put pressure on news corporations to bargain with them. This case study is situated in the local institutional contexts of labor relations at the Peterborough Examiner and the news industry in Peterborough, where Thomson Newspapers had a media monopoly. It is based on labor standpoint and signal juncture analyses of union archival documents and newspaper content. The research ultimately suggests that newsworkers should not only focus on communication tools but also build bridges with community members.  相似文献
