Cost-effective ways of delivering enquiry services: a rapid review     

Sutton A  Grant MJ 《Health information and libraries journal》2011,28(4):249-255

Background: In the recent times of recession and budget cuts, it is more important than ever for library and information services to deliver cost‐effective services. Objectives: This rapid review aims to examine the evidence for the most cost‐effective ways of delivering enquiry services. Methods: A literature search was conducted on LISA (Library and Information Sciences Abstracts) and MEDLINE. Searches were limited to 2007 onwards. Results: Eight studies met the inclusion criteria. The studies covered hospital and academic libraries in the USA and Canada. Services analysed were ‘point‐of‐care’ librarian consultations, staffing models for reference desks and virtual/digital reference services. Conclusions: Transferable lessons, relevant to health library and information services generally, can be drawn from this rapid review. These suggest that ‘point‐of‐care’ librarians for primary care practitioners are a cost‐effective way of answering questions. Reference desks can be cost‐effectively staffed by student employees or general reference staff, although librarian referral must be provided for more complex and subject‐specific enquiries. However, it is not possible to draw any conclusions on virtual/digital reference services because of the limited literature available. Further case analysis studies measuring specific services, particularly enquiry services within a health library and information context, are required.  相似文献   

Effectiveness of bibliographic searches performed by paediatric residents and interns assisted by librarians. A randomised controlled trial

Background: Considerable barriers still prevent paediatricians from successfully using information retrieval technology. Objectives: To verify whether the assistance of biomedical librarians significantly improves the outcomes of searches performed by paediatricians in biomedical databases using real‐life clinical scenarios. Methods: In a controlled trial at a paediatric teaching hospital, nine residents and interns were randomly allocated to an assisted search group and nine to a non‐assisted (control) group. Each participant searched Pub Med and other online sources, performing pre‐determined tasks including the formulation of a clinical question, retrieval and selection of bibliographic records. In the assisted group, participants were supported by a librarian with ≥5 years of experience. The primary outcome was the success of search sessions, scored against a specific assessment tool. Results: The median score of the assisted group was 73.6 points interquartile range (IQR = 13.4) vs. 50.4 (IQR = 17.1) of the control group. The difference between median values in the results was 23.2 points (95% CI 4.8–33.2), in favour of the assisted group (P‐value, Mann–Whitney U test: 0.013). Conclusions: The study has found quantitative evidence of a significant difference in search performance between paediatric residents or interns assisted by a librarian and those searching the literature alone.  相似文献

Building a Better Knowledgebase: A Community Perspective     

Katherine Hill  Maria Collins 《期刊图书馆员》2014,66(1-4):106-114

This article is a report of a concurrent session presented by Katherine Hill and Maria Collins of North Carolina State University (NCSU) Libraries at the 2013 North American Serials Interest Group conference. NCSU Libraries is a participant in the Global Open Knowledgebase (GOKb) project, which will provide an openly available knowledgebase for Kuali Open Library Environment (OLE). Results from a survey conducted by NCSU librarians are discussed, which focus on the e-resource management community and their expectations of the data provided in knowledgebases. The survey investigates problems and improvements in respect to data quality. Respondents also commented on their expectations of a community-managed project as well as the viability of a project like GOKb. Future directions and initiatives in the knowledgebase space were also summarized in the presentation.  相似文献   

Scientific Investigations of Elementary School Children     

Nicos Valanides  Maria Papageorgiou  Charoula Angeli 《Journal of Science Education and Technology》2014,23(1):26-36

The study provides evidence concerning elementary school children’s ability to conduct a scientific investigation. Two hundred and fifty sixth-grade students and 248 fourth-grade students were administered a test, and based on their performance, they were classified into high-ability and low-ability students. The sample of this study was randomly selected and included 80 students, 40 fourth-grade and 40 sixth-grade students of low and high abilities. Students were specifically instructed to investigate the functioning of a device, to think aloud prior and after any experiment with the device, and to keep a record of their experimental results. The results showed that students were inclined to mainly collect evidence from the experimental space and failed to control variables during their investigation. The majority of the students had difficulties with effectively organizing collected data and failed to coordinate hypotheses with evidence. The significant interaction effect that was found between grade level and ability in terms of students’ investigation ability indicates that the existing gap between high- and low-ability students becomes bigger as students become older. Undoubtedly, ongoing research efforts for identifying patterns of children’s cognitive development will be most valuable as they can have important implications for the design of teaching scenarios and inquiry-based science activities conducive to accelerating students’ cognitive growth and scientific investigation abilities.  相似文献
