Using the results of an Email survey, this paper reviews the use of Web 2.0 technologies by librarians working in UK Medical Schools. Web 2.0 has been hailed as an innovation for facilitation of two way communication on the net, and it is, therefore, timely to measure how effectively librarians are capturing this opportunity for increased student engagement. The social nature of Web 2.0 can be particularly appropriate for undergraduate medical students who fit their studies around the unsocial hours and geographical isolation of clinical placements. This paper will investigate library use of blogs, Facebook, and Twitter. Consideration will also be given as to whether they facilitate a more collabroative library service or if they leave undergraduate medical students swamped with yet more information to manage. 相似文献

The experiences of medical students, residents, and faculty with a computerized literature searching system were evaluated. Third-year medical students, internal medicine and family practice residents, and full-time and voluntary faculty at one medical school had the opportunity to use a full-text and bibliographic medical literature retrieval system free of charge for an eleven-month period. Subjects conducted nearly nine thousand literature searches over a period of 942 system hours. Questionnaire data showed that participants could learn to use and would use an electronic information system, felt capable of using the system, utilized the system for a variety of purposes and in a number of different ways, and viewed the system as a valuable tool in searching the medical literature. The results are discussed in the context of the educational needs of the four user-groups and medical education planning by institutions. 相似文献

BACKGROUND: Numerous studies deal with the use of computers and the Internet in the health sector. Most of these studies show an increase in the use of the new technologies in searching for medical information-particularly by patients--but these uses remain very heterogeneous and depend on the studies. AIMS: The aim of this work was to consider the use of computers by French general practitioners (GPs) and to analyse the impact that computerization could have on their information-seeking behaviour. METHODS: The nature of the approach used is qualitative using interviews. RESULTS: Most of the GPs interviewed are equipped with a computer. The policies of the government were supposed to give financial incentives for GPs to start using computers for the management of administrative procedures, but many physicians do not know how to use the new tools properly. Their computers are, in most cases, underused for searching for medical information. Most of the time, the Internet sources are thought to be unreliable. CONCLUSION: This study sheds light on the use of computers and the preferences of GPs in searching for medical information. 相似文献

Although a growing number of studies are examining the relationship between Internet use and political participation, varying study characteristics make the overall effect size difficult to estimate. Using a meta-analysis, we estimated the mean effect size and tested whether the effect size was influenced by study characteristics. Data for this meta-analysis were derived from 56 papers reporting 63 independent studies. Results revealed that Internet use had a weak relationship with political participation (rc?=?.22). Moderator analyses demonstrated that type of Internet use, Internet use measure, Internet use for news, type of political participation, sample origin, and survey year significantly moderated the relationship between Internet use and political participation. For instance, Internet use including news (rc?=?.27) had a significantly stronger relationship with political participation than did Internet use excluding news (rc?=?.19). European samples (rc?=?.27) had the largest mean correlation followed by North American samples (rc?=?.23) and Asian samples (rc?=?.18) in decreasing order of strength of relationship. The theoretical and methodological implications of the findings are discussed. 相似文献

The objective of this study is to provide data on one aca-demic medical library's experience with first and second year medical students’ use of interlibrary loan at the Indiana University School of Medicine–Northwest, Steven C. Beering Medical Library. The results of a study of 18 years of data show a substantial decline of interlibrary loans by medical students. Several factors, including the unique problem-based learning curriculum and the availability of online journals, which has expanded a small medical library's collection, may be responsible for the reduction of interlibrary loan. This study suggests the need for collection development librarians to understand their medical school curriculum and to invest in the most useful electronic journals for their medical students’ education needs. 相似文献

The internet is an important source of medical knowledge for everyone, from laypeople to medical professionals. We investigate how these two extremes, in terms of user groups, have distinct needs and exhibit significantly different search behaviour. We make use of query logs in order to study various aspects of these two kinds of users. The logs from America Online, Health on the Net, Turning Research Into Practice and American Roentgen Ray Society (ARRS) GoldMiner were divided into three sets: (1) laypeople, (2) medical professionals (such as physicians or nurses) searching for health content and (3) users not seeking health advice. Several analyses are made focusing on discovering how users search and what they are most interested in. One possible outcome of our analysis is a classifier to infer user expertise, which was built. We show the results and analyse the feature set used to infer expertise. We conclude that medical experts are more persistent, interacting more with the search engine. Also, our study reveals that, conversely to what is stated in much of the literature, the main focus of users, both laypeople and professionals, is on disease rather than symptoms. The results of this article, especially through the classifier built, could be used to detect specific user groups and then adapt search results to the user group. 相似文献

This paper reports on the results of a survey of sixty-six graduates of the University of Missouri-Kansas City (UMKC) School of Medicine conducted in the spring of 1977. The graduates were questioned about their present library use behavior and their restrospective perceptions of the clinical medical librarian (CML) services which they received as medical students at UMKC. The results show that these young physicians, after regular association with other, more tradional medical library services, hold very positive impressions of the CML program. The graduates also typically credit the CML'S with helping them to learn to use library resources effectively. These retrospective perceptions of the CML match the short-term benefits reported in other studies of similar programs. 相似文献

Our objective was to perform a pilot study to estimate the proportion of published errata linked to randomized controlled trials (RCTs) that are worthwhile obtaining when doing a systematic review. medline was searched for records that had both 'randomized-controlled-trial' in the publication type field and 'erratum' in the comments field. One hundred records from four general medical journals were examined independently from two different perspectives. From the information specialist's perspective, 74% of the errata were considered worthwhile obtaining; these were mainly errors in tables or figures. Another 9% described less serious errors, but were worth obtaining if easily available. The other 17% were minor errors. From the perspective of the experienced reviewer/public health consultant, 5% of errata were classified as likely to affect a meta-analysis, and 10% as having significant errors that would affect the interpretation of the RCT, but no effect on a meta-analysis; 85% were not considered important enough to affect either. About 5% of errata to RCTs appeared to matter in terms of changing the final conclusions of a systematic review. However, the majority of errata were considered to be worthwhile obtaining, on the basis that having full and accurate data can reduce confusion and save reviewers time. 相似文献

Problem-based medical education: effect on library use. 总被引：1，自引：0，他引：1
J A Rankin 《Bulletin of the Medical Library Association》1992,80(1):36-43
Problem-based learning (PBL) is being adopted by U.S. medical schools. Information-seeking skills are central to the PBL curriculum, which emphasizes self-directed learning and the acquisition of problem-solving and lifelong learning skills. The purpose of this study is to begin exploring the relationship between the PBL curriculum and student information and library use. Medical students in PBL and conventional medical school curricula were compared on library and information-seeking competencies, behaviors, and perceptions. A survey was sent to second-year students in four medical schools, two schools with two curricular tracks (one PBL and one conventional), one PBL school, and one conventional school. The results showed certain significant differences (P less than 0.05) between PBL and conventional curriculum students, suggesting that PBL students were the more frequent library users, used information resources that supported the independent learning process, acquired information-seeking skills at an earlier stage in their medical education, and reported greater ease in using these skills. 相似文献

This paper reports findings from an analysis of medical or health queries to different web search engines. We report results: (i). comparing samples of 10000 web queries taken randomly from 1.2 million query logs from the AlltheWeb.com and Excite.com commercial web search engines in 2001 for medical or health queries, (ii). comparing the 2001 findings from Excite and AlltheWeb.com users with results from a previous analysis of medical and health related queries from the Excite Web search engine for 1997 and 1999, and (iii). medical or health advice-seeking queries beginning with the word 'should'. Findings suggest: (i). a small percentage of web queries are medical or health related, (ii). the top five categories of medical or health queries were: general health, weight issues, reproductive health and puberty, pregnancy/obstetrics, and human relationships, and (iii). over time, the medical and health queries may have declined as a proportion of all web queries, as the use of specialized medical/health websites and e-commerce-related queries has increased. Findings provide insights into medical and health-related web querying and suggests some implications for the use of the general web search engines when seeking medical/health information. 相似文献

Objectives: This study surveyed Web 2.0 application in three types of selected health or medical‐related organisations such as university medical libraries, hospitals and non‐profit medical‐related organisations. Methods: Thirty organisations participated in an online survey on the perceived purposes, benefits and difficulties in using Web 2.0. A phone interview was further conducted with eight organisations (26.7%) to collect information on the use of Web 2.0. Data were analysed using both quantitative and qualitative approaches. Results: Results showed that knowledge and information sharing and the provision of a better communication platform were rated as the main purposes of using Web 2.0. Time constraints and low staff engagement were the most highly rated difficulties. In addition, most participants found Web 2.0 to be beneficial to their organisations. Conclusions: Medical‐related organisations that adopted Web 2.0 technologies have found them useful, with benefits outweighing the difficulties in the long run. The implications of this study are discussed to help medical‐related organisations make decisions regarding the use of Web 2.0 technologies. 相似文献
