Real-time,evidence-based medicine instruction: a randomized controlled trial in a neonatal intensive care unit

Purpose: The study assesses potential for improving residents'' evidence-based medicine searching skills in MEDLINE through real-time librarian instruction.Subjects: Ten residents on a rotation in a neonatal intensive care unit participated.Methodology: Residents were randomized into an instruction and a non-instruction group. Residents generated questions from rounds and searched MEDLINE for answers. Data were collected through observation, search strategy analysis, and surveys. Librarians observed searches and collected data on questions, searching skills, search problems, and the test group''s instruction topics. Participants performed standardized searches before, after, and six-months after intervention and were scored using a search strategy analysis tool (1 representing highest score and 5 representing lowest score). Residents completed pre- and post-intervention surveys to measure opinions about MEDLINE and search satisfaction.Results: Post-intervention, the test group formulated better questions, used limits more effectively, and reported greater confidence in using MEDLINE. The control group expressed less satisfaction with retrieval and demonstrated more errors when limiting. The test and control groups had the following average search scores respectively: 3.0 and 3.5 (pre-intervention), 3.3 and 3.4 (post-intervention), and 2.0 and 3.8 (six-month post-intervention).Conclusion: Data suggest that measurable learning outcomes were achieved. Residents receiving instruction improved and retained searching skills six-months after intervention.     

Educational workshop improved information-seeking skills,knowledge, attitudes and the search outcome of hospital clinicians: a randomised controlled trial

A double-blind randomised controlled trial was conducted on a group of Hong Kong hospital clinicians. The objective was to test if a three-hour educational workshop (with supervised hands-on practice) is more effective (than no training) to improve clinical question formulation, information-seeking skills, knowledge, attitudes, and search outcomes. The design was a post-test-only control group; recruitment by stratified randomization (by profession), blocked at 800. End-user training was more effective than no training in improving clinical question formulation, in raising awareness, knowledge, confidence and use of databases, but had made no impact on preference for secondary databases. It changed the attitude of clinicians to become more positive towards the use of electronic information services (EIS). Participants had higher search performance and outcomes (satisfaction with information obtained (NNT = 3), EIS satisfaction (NNT = 3) and success in problem solving (NNT = 4)). The workshop improved knowledge and skills in evidence-based searching, but this effect gradually eroded with time. Search logs confirmed that follow-up is required if effects are to be sustained. Longer effects on search behaviours appear to be positive. A randomised controlled trial is valuable in identifying cause-and-effect relations and to quantify the magnitude of the effects for management decision-making.     

Increasing the rural general practitioners' use of library and information services through publicity: a randomized controlled trial in Cornwall, UK

OBJECTIVES: To provide evidence on the effectiveness of publicity with the aim of encouraging general practitioners (GPs) in Cornwall to make better use of the Cornwall Health Library Service (CHLS). In the light of the findings, a second objective was formulated to determine which resources they used to look for health information. METHODS: A cluster randomized controlled trial (RCT) measured the effect of two types of publicity, comparing emails with visiting GP practices. After the trial period, a questionnaire was sent to all 332 GPs to ascertain the resources they accessed for their information and any barriers to their use of the CHLS. RESULTS: The GP's use of the library services was lower than the level needed for a conclusive statistical analysis; however, visiting practices was associated with an apparent increase in library use and warrants further investigation. The questionnaire showed that GPs make good use of databases and colleagues. CONCLUSION: The RCT confirmed the low uptake of library services anticipated, but was inconclusive in demonstrating the most effective form of publicity. The questionnaire suggested that a substantial number of GPs are interested in the library services and has provided an insight into the way that GPs look for information in Cornwall.     

Analysis of characteristics and trends of Web queries submitted to NAVER,a major Korean search engine

This study investigates the information seeking behavior of general Korean Web users. The data from transaction logs of selected dates from August 2006 to August 2007 were used to examine characteristics of Web queries and to analyze click logs that consist of a collection of documents that users clicked and viewed for each query. Changes in search topics are explored for NAVER users from 2003/2004 to 2006/2007. Patterns involving spelling errors and queries in foreign languages are also investigated. Search behaviors of Korean Web users are compared to those of the United States and other countries. The results show that entertainment is the topranked category, followed by shopping, education, games, and computer/Internet. Search topics changed from computer/Internet to entertainment and shopping from 2003/2004 to 2006/2007 in Korea. The ratios of both spelling errors and queries in foreign languages are low. This study reveals differences for search topics among different regions of the world. The results suggest that the analysis of click logs allows for the reduction of unknown or unidentifiable queries by providing actual data on user behaviors and their probable underlying information needs. The implications for system designers and Web content providers are discussed.     

Two representations of the research process: The preparing,searching, and using (PSU) and the beginning,acting and telling (BAT) models

Two representations of a three-stage diagrammatic model that holistically depicts the research process are presented. The representations incorporate elements culled from existing information-seeking behavior and information literacy instruction research, as well as evidence gathered from a study of third grade elementary school students, as they worked to fulfill a class project's requirements. Both representations are content independent, attribute equal importance to each of the three stages, and target the K-12 educational environment. The full representation, the preparing, searching, using (PSU) model, is intended for use by instructors and more advanced students. The model identifies elements inherent within the three stages of the research process including actions, affective behaviors, impact factors, learning, and reflection. The simpler representation, the beginning, acting, telling (BAT) model, which is embedded into the PSU, presents only the three main stages and the actions associated with those stages using a familiar graphic (a bat) and a mnemonic device to visually present the basic elements of the research process to younger elementary school students. The PSU model is designed to identify and address the unique information behaviors of students (affective, cognitive, and physical) and factors that may impact the research process. As a result, the representations can be used by educators, including information professionals and teachers, to inform instruction, such as lesson planning, development of assignments, resource location and evaluation, and the use of information, to fully exploit all aspects of the research process. The PSU model can also be used to teach more sophisticated concepts to older students by introducing more complex features gradually to the BAT model.

Impact of librarians in first-year medical and dental student problem-based learning (PBL) groups: a controlled study

BACKGROUND: Librarians at the University of Alberta have been involved with teaching undergraduate medical and dental education for several years. After 1 year of increased librarian involvement at the problem-based learning (PBL), small-group level, informal feedback from faculty and students suggested that librarians' participation in PBL groups was beneficial. There was, however, no real evidence to support this claim or justify the high demand on librarians' time. OBJECTIVES: The study aimed to determine whether having a librarian present in the small-group, problem-based learning modules for first-year medical and dental students results in an improved understanding of evidence-based medicine concepts, the nature of medical literature, and information access skills. METHODS: One hundred and sixty-four first-year medical and dental students participated in the study. There were a total of 18 PBL groups, each with approximately nine students and one faculty tutor. Six librarians participated and were assigned randomly to the six intervention groups. Students were given pre- and post-tests at the outset and upon completion of the 6-week course. RESULTS: Post-test scores showed that there was a small positive librarian impact, but final exam scores showed no impact. There was also no difference in attitudes or comfort levels between students who had a librarian in their group and those who did not. CONCLUSIONS: Impact was not sufficient to warrant continued participation of librarians in PBL. In future instruction, librarians at the John W. Scott Health Sciences Library will continue to teach at the larger group level.     

Comparing Physically Abused,Neglected, and Nonmaltreated Children During Interactions with their Parents: A Meta-Analysis of Observational Studies

A meta-analysis of 30 observational studies compares abused, neglected, and nonmaltreated children's behavior during interactions with their parents. Drawing on the relational communication literature, children's behaviors from various coding schemes were grouped into those communicating positivity (e.g., affection, approval), aversiveness (e.g., anger, resistance), and involvement (e.g., attention, interest). Results reveal that abused and neglected children are distinguished from nonmaltreated children on all three behavioral clusters, with overall mean weighted effect sizes ranging from d=.29 to .55. Several moderators qualify the magnitude though not the direction of these differences, including maltreatment type, child/parent age, and observation length and setting. These findings have implications for understanding the etiology and outcomes of child maltreatment as well as for intervention and prevention efforts.     

An Ethics of (not) Showing: Citizen Witnessing,Journalism and Visualizations of a Terror Attack

ABSTRACT

This paper explores how news organizations visualize crises in a digital media ecology shaped by citizen witnessing and widespread image circulation on social media. Empirically, the paper draws on the events of 7 April 2017 in Stockholm when a hijacked truck plowed into crowds, killing five and injuring several others. The study is informed by theoretical perspectives and research on citizen photojournalism and witnessing, and examines the function of visual citizen contributions, degrees of explicitness in visual coverage and the impact of proximity on visualizations of crises. Qualitative analyses of visual content and text in digital and print editions of four Swedish newspapers showed both enhancing and featured positioning of visual eyewitness contributions from the public, few examples of explicit imagery, and journalistic commentary foregrounding ethical dimensions of showing and seeing. Based on the findings, the author considers journalism’s civic response as a strategy for staking a claim to credibility and ethics at a moment when the journalistic gatekeeping position is called into question.

Routine and strategic maintenance efforts: behavioral patterns,variations associated with relational length,and the prediction of relational characteristics

The goal of the present study was to examine the patterns of relationships between routine and strategic maintenance enactment. Data were collected from 189 individuals in a romantic relationship. Results indicated that positivity and sharing tasks were more often performed routinely than strategically. Second, moderate to strong, positive correlations were found among the strategic use of maintenance behaviors, and also moderate to strong, positive correlations among the routine use of maintenance behaviors. However, virtually no relationships emerged between the routine and strategic use of maintenance. Next, both strategic and routine maintenance efforts were important in predicting satisfaction and commitment, but routine maintenance was slightly more important in predicting both satisfaction and commitment. Finally, three significant, positive correlations were found between the length of the relationship and routine maintenance performance (network, conflict management, and sharing tasks), and one significant, negative correlation was found between the length of the relationship and the strategic use of openness.     

Comparison of two article-level,field-independent citation metrics: Field-Weighted Citation Impact (FWCI) and Relative Citation Ratio (RCR)

We reproduce the article-level, field-independent citation metric Relative Citation Ratio (RCR) using the Scopus database, and extend it beyond the biomedical field to all subject areas. We compare the RCR to the Field-Weighted Citation Impact (FWCI), also an article-level, field-normalised metric, and present the first results of correlations, distributions and application to research university benchmarking for both metrics. Our analyses demonstrate that FWCI and RCR of articles correlate with varying strengths across different areas of research. Additionally, we observe that both metrics are comparably stable across different subject areas of research. Moreover, at the level of universities, both metrics correlate strongly.     

(De)stabilizing Sexual Violence Discourse: Masculinization of Victimhood,Organizational Blame,and Labile Imperialism

Following calls to center nation, we analyze sexual violence discourse in the US Peace Corps. The texts we consider deploy three typical dichotomies—public/private, self/other, and agent/victim—that, in this case, reveal inconsistencies at the intersections of race and gender. We argue that these inconsistencies are evidence of lability, counterintuitive discursive shifts necessary to maintain white heteromasculine dominance. Instead of blaming individual victims of rape and assault, the masculinization of victimhood shifts culpability to the Peace Corps. This organizational blame maintains the moral position of the US and legitimates imperialism. By marking these instabilities, we trace the solidity and vulnerability of sexual violence discourse as it organizes global power.
