Using actual news coverage of an environmental risk, this experimental study examined whether providing unrelated risk comparisons and information about other sources of the same risk influenced readers' reactions to the coverage. The study suggests stories that provide information on other sources of a contaminant may do little to reduce risk perceptions; however, providing information about the magnitude of the risk at hand relative to other risks had several communication benefits. Both comparisons lead readers to feel more informed about the risk and, thus, better able to make decisions than those who did not see the comparisons. Media implications are discussed. 相似文献

ABSTRACT Preexposure prophylaxis (PrEP) is an effective medicine against HIV transmission. PrEP can be especially beneficial in the men who have sex with men (MSM) communities. However, medical studies have associated MSM’s PrEP use with undesired riskier behaviors (risk compensation), such as reducing condom use and acquiring more sexual partners. Fact sheets are important information sources for MSM to learn about PrEP and can potentially prevent risk compensation. This study compared three accessible fact sheets (the Truvada fact sheet, the CDC fact sheet, the FDA fact sheet) in terms of their effects on MSM’s PrEP use intention and risk compensation intention (n = 600). The results showed that the CDC and the FDA fact sheets significantly encouraged higher PrEP use intention without provoking higher risk compensation intention. To promote PrEP use without raising risk compensation intention, fact sheets might be good information sources for the MSM population. 相似文献

Immigrants are among the populations in modern society that libraries are striving to serve. This study aims to develop a framework on immigrants, their information needs, and library services. Using a systematic literature review based on the grounded theory approach, 28 related articles were reviewed to identify the causes, characteristics, and the content of the information needs of immigrants. Also explored were the possible sources to satisfy these information needs and the barriers to accessing needed information. Findings indicate that personal social networks, the Internet, media sources, and institutions are the main information sources for immigrants; language, cultural differences, the digital divide, unfamiliar information systems, and psychological factors are the five major challenges for immigrants obtaining information. Based on the findings, a unified framework about immigrants, their information needs, sources to satisfy those needs, and library information services is, therefore, proposed. This framework may provide guidance for libraries and other information service agencies to better develop services and information systems for immigrants. 相似文献

Objective: With Web 2.0, the variety of information sources for parents of paediatric psychiatric patients has increased dramatically. Information use theory suggests newer sources supplement rather than supplant traditional sources of health information. This study sought to determine the use and value of traditional and emerging sources of information and whether the subjects had access to highly valued sources of information. Methods: One hundred parents indicated the use and value of six sources of information on the child’s symptoms, diagnoses and treatment. The data were analyzed to determine if significant relationships existed between type of source and the use and value of the information sources. Results: Ninety‐four percent of the subjects had access to the Internet and almost half of those reported using the Social Web. Eighty‐five percent had at least one high‐value information source. The psychiatrist in the clinic, the Internet and the primary care physician were the most highly used and valued sources. Conclusion: Use of digital information sources was greater than found in other studies of similar populations. This use appears to complement rather than supplant more traditional sources. Further studies are needed to see if the negative impact of lack of Internet access is replicated. 相似文献

Personal information management behaviors appear differently by sources and by context. This study investigates personal information spaces from a quantitative approach and factors specific information behaviors and sources into information contexts. Using the information source horizon theory as a theoretical framework, college students' information behaviors to specific information sources were investigated in three personal information contexts (academic, health, and personal history contexts). In the college setting, students' personal information horizons echo the findings of previous studies that information contexts determine information horizons in general. In addition, specific information behaviors (collect, organize, and utilize) in this study are an important factor to influence personal information horizons. Certain information activities are observed in similar patterns regardless of contexts. The study suggests that the Information Horizon theory could be expanded to include information behaviors as an important determinant. From the data, radar charts visually present the relationships between information sources and activities, and they served as a collective form of information horizon maps. 相似文献

Dentists, as health professionals, need access to information. As in other health sciences, the increase in the rate and volume of published information has made it more difficult for them to keep up with new developments. Five hundred randomly selected dentists in Louisiana were surveyed to determine what information dentists seek and what sources they prefer. Responses indicated that dentists need information on new techniques in dentistry and that preferred sources are professional colleagues and personal journal collections. Libraries were found to be used only infrequently as sources for information. Implications for planning libraries for applications- and technique-oriented professions are discussed. 相似文献

This study investigated which social media platforms are used as information sources, and for what purposes. It also examined how user characteristics are related to the use of different platforms. A Web-based survey was used to collect data from undergraduate students. Responses from more than 800 students showed that most of the social media platforms are used as information sources, where wikis, user reviews, and media-sharing sites emerged as the top platforms. The purpose of use varied across platforms. T-test and ANOVA results also revealed individual differences. Significant differences in gender, class level, academic discipline, and Big Five personality traits were found in the frequency of information seeking using different platforms and also in the purpose of use. Study findings have implications for information literacy (IL) education and information services. Because many students are actively using social media platforms for a variety of information-seeking purposes, it is suggested that IL programs embrace social media as potential information sources and offer effective strategies for using and evaluating these increasingly popular social media sources. 相似文献

Much of health research that examines patterns of health utilization for chronic drug users fails to account for the role of media use and health information seeking. This paper suggests that the nature of drug use is associated with a decreased health orientation that is manifested in media selection and consumption. A comparative analysis was conducted to examine: (1) the differential health perceptions as a function of drug use, (2) the sources of information used, and (3) the relationship between sources of information and primary health care access among chronic users of illicit drugs and socio-demographically similar persons who are not chronic drug users. Results point to both common as well as differential patterns of health information sources. Logistic regression analysis found that medically related sources such as doctors and pamphlets are important sources associated with increased primary care. Important implications are discussed. 相似文献

As new venues of information and tools for information access are emerging, people's online information seeking behavior is dramatically evolving. While a majority of well-established and classical models of information seeking and behavior are still valid, there is a growing need to study and explain novel information sources and information seeking behaviors that are unique to these sources. One emerging domain is social question and answer (Q&A). This article develops a research agenda for social Q&A, reviewing recent studies and identifying core issues, questions, and challenges. 相似文献

ABSTRACT Forecasts suggest that changes in the nature of business and trends in business education will lead to a sharp need for and demand for industry information in libraries. The need for industry sources is diverse, ranging from highly specialized to general, and industry information can be found in a broad spectrum of sources. Unfortunately most sources are expensive and so a small undergraduate library will have difficulty meeting demand. To help meet the need for increased use and demand, this paper outlines and provides abstracts to many free sources of industry information available on the Web. While these do not offer a total substitute for commercial sources, they will satisfy some needs, allowing the library to spend its money on information that is not readily found free on the Internet. 相似文献

The number of information sources available through both printed and electronic media are ever increasing. Even libraries with sizable collection development budgets are having difficulties in coping with this increase. Yet with the development of new technologies, the possibilities of innovative interlibrary cooperation projects emerge: libraries combining their efforts through various consortia are trying to get access to electronic information sources more economically. In this paper, we briefly review the state-of-the-art of Turkish university libraries and summarize the efforts to set up a university library consortium to provide consortial access to electronic information sources and services. We discuss some of the causes which are delaying the establishment of such a consortium. 相似文献

This paper attempts to make a comparison between a western culture, Canada, and an eastern culture, China, in the use of business information. As part of a larger project of measuring the impact of information on development, four surveys of the business communities in these two countries were conducted. Two of them were carried out in Shanghai, China, with one aimed at small business and the other at medium-sized business. The other two were conducted in Canada with the same coverage as the corresponding surveys in China. Data were collected on the use of various types of information sources in business operations. Results show that informal information sources are more important and better used than the formal ones in both cultures. However, business people's self-perception of their information use differs between the two cultures. Electronic information sources are currently poorly used in both countries. 相似文献

The purpose of this chapter is to address the issues of information seeking behavior within a context of an information poor life style. Several factors can be attributed to an information poor world. For example, it is one in which the mass media are not viewed as providers of useful information. Moreover, this is a world in which there is a parsimony of helpful interpersonal channels. Thus, both formal and personal sources are devoid of everyday practical information of the kind that is needed by poor people. In addressing reasons to explain this phenomenon, knowledge gap theory is examined. The conclusion drawn from this analysis is that, although the mass media are perceived as sources of information for some (the "media rich"), they do not respond to the needs of the poor. Unfortunately, the role that interpersonal sources might play in this process, have not been adequately addressed by knowledge gap researchers. 相似文献

Libraries will be changed by technological and social developments that are fueled by information technology, bioinformatics, and networked information. Libraries in highly focused settings such as the health sciences are at a pivotal point in their development as the synthesis of historically diverse and independent information sources transforms health care institutions. Boundaries are breaking down between published literature and research data, between research databases and clinical patient data, and between consumer health information and professional literature. This paper focuses on the dynamics that are occurring with networked information sources and the roles that libraries will need to play in the world of medical informatics in the early twenty-first century. 相似文献

Parents are an important source of advice when adolescents are faced with decisions about postsecondary education and career planning; however, parents often need to seek information to facilitate their child’s career development. This study applies the theory of motivated information management (TMIM) to evaluate the decision-making process parents undergo in this context and tests the boundaries of TMIM by considering how individuals use face-to-face (FtF) and online sources to alleviate uncertainty-related anxieties. A community sample of parents (N?=?937) completed a survey regarding their information seeking behaviors surrounding their adolescent’s career development. Parents reported using both FtF and online sources to seek information about their child’s postsecondary plans, and they engaged in different evaluative processes depending on the source of information. Theoretical implications related to TMIM and practical implications related to parents as sources of information in adolescent career development are discussed. 相似文献
