Comparison of three web-scale discovery services for health sciences research     

Rosie Hanneke  Kelly K. O'Brien 《Journal of the Medical Library Association》2016,104(2):109-117

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.  相似文献   

大学图书馆本科生流通服务工作重构依据及其实证研究     

潘颖  刘利  杨贺晴 《图书馆理论与实践》2020,(2):19-25,55

为了明晰纸本图书的存在价值,为图书馆流通服务的转型提供参考,本文选取某高校2011级4个学院本科毕业生为研究样本,将借阅数据与成绩数据相关联,从借阅册数、文献类别、借阅时间、利用周期4个维度对本科生纸本图书借阅与课程成绩的相关性和贡献度进行实证分析。研究表明,纸本资源对于学生学习的作用并未下降,应明确面向本科生的图书馆纸本资源流通服务方向,有效整合馆员、资源、空间等要素,以重构流通服务模式及流程。  相似文献   

Adverse experiences in early childhood and their longitudinal impact on later behavioral problems of children living in poverty     

《Child abuse & neglect》2019

BackgroundAdverse childhood experiences (ACEs) are an identified risk factor for the social and emotional development of children. What is less known is the long-term effects of ACEs when poverty and ACEs coincide.ObjectiveUsing longitudinal cohort-panel data, we examined whether exposure to ACEs by the age of three among poor children would longitudinally result in behavioral problems at ages three, five, nine, and 15, after controlling for mothers’ socioeconomic status and their children’s characteristics.Participants and settingWe used a subsample of 2750 children and their parents living in urban poverty from the Fragile Families and Child Wellbeing study.MethodsLogistic regression modeling was used to obtain adjusted odds ratios of ACE categories predicting behavioral problems after accounting for family socioeconomic position.ResultsOur findings indicate that experiencing ACEs in early childhood was significantly associated with later behavioral outcomes from childhood to adolescence. Exposure to multiple ACEs before the age of three was significantly associated with the top-risk behavior group at age five; the odd ratios were 2.0 (CI = 1.3–3.1) and 2.9 (CI = 1.8–4.6) for two ACEs and three or more ACEs, respectively. At both ages nine and 15, children experiencing two or more ACEs had 1.9 to 3.2 times higher odds to demonstrate more the top 10th percentile of behavioral problems. Among covariates, mothers’ race and education, and children’s gender and temperament were identified as significant factors to determine behavior problems.ConclusionsThe findings support policies and programs for families with children who have experienced economic disadvantages and early childhood adversity.  相似文献   

A mediational model linking perceptions of security,alexithymia and behavior problems of sexually abused children     

《Child abuse & neglect》2019

BackgroundPerceptions of security toward parents are related with internalized and externalized problems among victims of child sexual abuse (CSA). Alexithymia, which is difficulty in identifying and expressing feelings, is associated with the quality of parent-child relationships (Oskis et al., 2013) and behavior problems in children (Di Trani et al., 2013).ObjectiveThe current study tested the mediational role of alexithymia in the relationship between perceptions of security toward parents and behavior problems among CSA victims.Participants and methodUsing a short-term multi-informant prospective design, 263 victims of CSA aged 6–12 years completed the Kerns Security Scale (Kerns, Klepac, & Cole, 1996), which evaluates perceived attachment security to mothers and fathers. Parents completed the Child Behavior Checklist (Achenbach & Rescorla, 2001) at Time 1 to provide baseline scores of behavior problems and again four months later. At Time 2, parents also assessed the children’s alexithymia using the Children’s Alexithymia Measure (Way et al., 2010).ResultsPerceptions of security were both associated with alexithymia, as well as with internalizing and externalizing problems (p < .05). A mediational model showed that perception of security toward fathers outweighed the mother-child relationship in predicting children’s alexithymia. Path analysis revealed that the father-child relationship predicted decreased behavioral problems at Time 2 through a lower level of alexithymia. The model explained 46.9% of internalizing problems and 56.1% of externalizing problems (p < .05).ConclusionsThe findings support the relevance of alexithymia as an intervention target for CSA victims and underscore the importance of the father-child relationship.  相似文献   

图书借阅量配额管理困境的原因及对策     

陈厚莹 《高校图书馆工作》2011,31(3):25-27

图书借阅量应具备一定的＂质量＂,但目前其配额数量保守、配额依据缺失、配额时限固定给图书借阅造成了不良影响。究其原因在于重藏轻用的传统观念、读者阅读的多样诉求、滞后的图书借阅技术、不太友好的图书借阅环境等。需要从树立藏书与利用的正确观念、升级图书馆管理系统的借阅功能、重新定位图书馆的角色等方面采取措施加以解决。参考文献8。  相似文献
