News changes constantly. That change and the abundance of Web-based news resources available complicate finding the news. This paper reviews sixteen different online news sources for their coverage of recent health and medical issues; both general-interest and medical news sites are included. Three health-related news stories were searched in all resources within set time-frames to provide a comparison of coverage. Features and types of resources are described. The use of RSS feeds and weblogs to find news is also discussed with suggestions for using news aggregators to control the flow of information. 相似文献

To combat the constant supply of negative news, some online news outlets focus solely on “good” news. But what is the value of “good” news? A content analysis was conducted to determine which traditional news values (timeliness, conflict, impact, etc.) appear in stories on Web sites dedicated to positive news. The researcher compared “good” news sites to the New York Times. Results indicated that the majority of “good” news stories were entertaining and emotional, whereas the majority of New York Times stories involved authority figures and conflict. Good news stories were less committed to journalism’s core functions, such as holding power accountable and providing the public with information necessary for creating an informed electorate. 相似文献

This paper provides an overview of the research into current medical vocabularies and their impact on searching the Web for health information. The Web provides growing opportunities for laypersons to gain knowledge about specific health conditions, though research to date has been incomplete. Many studies have examined aspects of controlled medical vocabularies. Other studies have examined aspects of medical Web searching vocabularies. In this context, there is a growing need to examine more closely laypersons' Web queries using controlled medical vocabularies that were designed to serve the needs of medical professionals. It may be the case that the average consumer of Web health services is not able to use correct medical terminology, and may not be able to choose analogous or synonymous terms from a search result list. Our review suggests a growing need for studies to examine the current applicability of controlled medical vocabularies as well as alternatives to semantic query by Web search engine users. 相似文献

A within-subjects experiment explored how the number of online, hyperlinked stories available for individuals to choose from affects cognitive processing of a selected story. Participants chose and read unpleasant online news stories from a Web page containing either 5 or 15 headline/photo hyperlinks. Heart rate data indicated more cognitive resources were allocated to reading stories selected from the larger array of hyperlinks. This increased allocation of cognitive resources also led to more accurate story recognition. Results of this study provide insight into information processing of interactive, online news as well as limited suggestions for the design of news Web sites. 相似文献

An increasing number of medical school libraries offer chat service to provide immediate, high quality information at the time and point of need to students, faculty, staff, and health care professionals. Part 2 of Chat Reference Service in Medical Libraries presents a snapshot of the current trends in chat reference service in medical school libraries. In late 2002, 25 (21%) medical school libraries provided chat reference. Trends in chat reference services in medical school libraries were compiled from an exploration of medical school library Web sites and informal correspondence from medical school library personnel. Many medical libraries are actively investigating and planning new chat reference services, while others have decided not to pursue chat reference at this time. Anecdotal comments from medical school library staff provide insights into chat reference service. 相似文献

Physicians are becoming aware of the World Wide Web as a resource for medical information. In spring 1999, first-year students at the University of Louisville's School of Medicine were given an assignment to review and evaluate Internet search engines and directories, medicine-specific search engines and meta lists, and health-related Web sites. Students found that general search engines were easier to learn and use and produced better results than either meta medical sites or medicine-specific search engines. Students were very severe in judging the quality of health-related Web sites. Our students' impressions are compared to those of physicians in similar studies. Solutions to the problems of searching the Web for health information are reviewed. 相似文献

This is the final biennial update listing directories, journal articles, Web sites, and general books that aid the librarian, house officer, or medical student in finding information on medical residency and fellowship programs. The World Wide Web provides the most complete and up-to-date source of information about postgraduate training programs and specialties. This update continues to go beyond postgraduate training resources to include selected Web sites and books on curriculum vitae writing, practice management, personal finances, the "Match," certification and licensure examination preparation, lifestyle issues, job hunting, and the DEA license application process. Print resources are included if they provide information not on the Internet, have features that are particularly useful, or cover too many relevant topics in depth to be covered in a journal article or on a Web site. The Internet is a major marketing tool for hospitals seeking to recruit the best and brightest physicians for their training programs. Even the smallest community hospital has a Web site. 相似文献

This paper follows the news routine of the daily evening news broadcasts of the two Israeli commercial TV channels. It is about a very particular and significant moment in national TV news—the making and gatekeeping process of the national TV news filler, also known by the Israeli news people as the shelf item. Based on a thematic analysis of in-depth interviews with several Israeli TV news professionals and a textual analysis of a particular TV news item and its shelf potential, findings provide a glimpse at how and for what reasons news stories are prioritized, how gatekeeping is performed in national TV news, and the ways in which the stories that are kept aside and left for later illustrate the overall production of newsworthiness. 相似文献

SUMMARY RSS technology is growing in popularity among libraries as a way to distribute, or syndicate, information about new electronic resources and Web content to users. “Really Simple Syndication” is an effective communication tool for libraries because it supplies the user with to up-to-date links and announcements on the library Web site after only one initial setup function. RSS does not require the user to make frequent visits to the library Web site for updated information; rather, it gathers content from any Web sites designated by the user, and delivers news to the users in an aggregated format. The benefits of RSS are that the software to setup the service is often free for downloading and many users are already familiar with the application. The “orange button” now present on so many commercial Web sites ranging from news sites to blogs is gaining a presence on library Web sites. 相似文献

This article investigates and interprets social and cultural production and reproduction as we turn our attention to an important part of routinised practice in the newsroom: the early newsroom meetings. These meetings are essential sites for the building of the craft ethos and professional vision. Our aim is to study how this building of expertise takes place at meetings with a particular focus on the decision-making process concerning ideas for new news stories. In order to do this, we perform linguistic analysis of news production practices, as we investigate how the journalists' ideas for potential news stories are eliminated by the editor at the daily newsroom meetings. The elimination of ideas for news stories are not just eliminations; they are also corrections of culturally undesirable behaviour producing and reproducing the proper perception of an important object of knowledge—what constitutes “a good news story”—in this community of practice. 相似文献

Health professionals and members of the public are often interested in locating exercise information on the World Wide Web (the Web). There is a large amount of information available on the Web; however, the challenge for all people is to identify the high quality information that can be depended upon. Much of the quality exercise information on the Web is hidden within sites of reputable organizations concerned with exercise and health. This article examines several categories of commonly needed exercise related information. For each category, a few high quality sources of exercise information are listed. Combined, these Web sites provide an excellent and extensive body of knowledge for a person who is not experienced with exercise and wants to get started learning, or for a person with a moderate level of experience and knowledge who wants to learn more. 相似文献

This experiment tested the interaction of media channels (television, newspaper, and the Web), time delay, and the education level of audience members, using three memory measures. The lower education group encoded, stored, and retrieved television news information best while they showed less memory capacity for newspaper and Web news. For the higher education group, the opposite pattern emerged. They had better memory for newspaper and Web versions of news, compared to television. With time delay, these patterns persisted. They were also robust when controlling for participant evaluations of the news stories in terms of interest, informativeness, and understandability. 相似文献

The Internet continues to grow as an information and entertainment medium. Internet growth has implications for the news industry. Twenty-four hour news networks such as CNN and MSNBC regularly encourage viewers of their television programs to visit their Web sites. While visiting news Web sites, visitors are invited to participate in opinion polls. Unfortunately, these online opinion polls are not scientific and have little real news value. In spite of these limitations, news Web sites' Internet polls are often treated as serious topics in broadcast news discussions. This article examines media organizations' Internet online polls and critiques them as instances of symbolic representation and pseudo-events that have arisen largely out of the integration of print, broadcast, and Internet media. 相似文献

The ability to add hyperlinks to a news story is a key feature of online news. In addition to the—aging—technical novelty, one can wonder what functions hyperlinks perform in news stories. Previous research, as well as my previous examination of meta-journalistic discourses, has shown that one of the alleged functions of links is to display the writer's sources. In that sense, hyperlinks are “journalistic objects of evidence” as they can directly point to the documents, data or discourses used as rough material for a news story. The present paper puts that particular function of hyperlinks to the test. It conducts a content analysis on a sub-sample of the stories published on six Belgian news sites that contain at least one external link, and compares the links with the sources explicitly mentioned in the news story itself. Results highlight that links and the mentions of sources do not overlap completely. Many sources are not reflected in links, and most links do not point to primary sources per se. Other functions of links emerge, such as providing a service or contextual information to the readers. These findings thus question the material nature of “journalistic objects of evidence” and the possibility for journalists to build networks of distributed responsibility with links. 相似文献

Gatekeepers usually control news information. However, recent technological advancements might require rethinking previous gatekeeping hierarchies. Aggregation algorithms currently filter and present news information to millions of American Internet users daily. A content analysis demonstrates significant differences between health news content retrieved from Web sites that aggregate their articles from many sources (e.g., Google News), and those that focus on providing news from a limited number of sources (e.g., CNN.com). Explanations for these content differences are discussed, as are implications concerning health information seeking and Internet news consumption. 相似文献

This study examines independent news startups with self-reported revenue earnings in high-, middle-, and low-income categories and compares them in the areas of news content creation. The findings, based on a content analysis of 704 articles, reveal that low-revenue earners publish fewer stories than middle- and high-revenue earning sites. For-profit sites publish significantly more in low- and mid-revenue earning categories but non-profits publish significantly more in high-revenue earning sites. Most stories are still covered by editorial staff, including articles in the field of entertainment, lifestyle/health and community events about people, usually considered the domain of citizen reporters. The discussion section contextualizes these findings and recommends future research could consider examining these sites separately rather than clubbing them under the umbrella of “digital local independent startups.” 相似文献
