Meeting Information Needs through Global Partnerships: A Roadmap to Becoming a Global Health Sciences Library

Abstract

Supporting global health priorities through the development of robust health science librarianship partnerships is of significant importance. Increased demand for synthesizing evidence-based information, collating quality resources, and increasing research productivity to improve human health requires integration of library and information science skills and expertise. The Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill (UNC), exists to be an indispensable partner in health information and knowledge, teaching and learning, and research. As global efforts at UNC expanded, the HSL sought to ensure that our global engagement strategy and integration were aligned with campus priorities and partner needs. The HSL created a global research partnership plan: identify resources that improve efficiency, increase access to information, build in-country capacity and expertise—all while strengthening collaborations across multiple countries. Creating a meaningful and sustainable engagement strategy was central to envisioning our path forward and can be used as a framework for consideration by librarians in similar settings.  相似文献   

Tracking user-role evolution via topic modeling in community question answering     

Chaogang Fu 《Information processing & management》2019,56(6):102075

Community question answering (CQA) services that enable users to ask and answer questions are popular on the internet. Each user can simultaneously play the roles of asker and answerer. Some work has aimed to model the roles of users for potential applications in CQA. However, the dynamic characteristics of user roles have not been addressed. User roles vary over time. This paper explores user representation by tracking user-role evolution, which could enable several potential applications in CQA, such as question recommendation. We believe this paper is the first to track user-role evolution and investigate its influence on the performance of question recommendation in CQA. Moreover, we propose a time-aware role model (TRM) to effectively track user-role evolution. With different independence assumptions, two variants of TRM are developed. Finally, we present the TRM-based approach to question recommendation, which provides a mechanism to naturally integrate the user-role evolution with content relevance between the answerer and the question into a unified probabilistic framework. Experiments using real-world data from Stack Overflow show that (1) the TRM is valid for tracking user-role evolution, and (2) compared with baselines utilizing role based methods, our TRM-based approach consistently and significantly improves the performance of question recommendation. Hence, our approach could enable several potential applications in CQA.  相似文献   

The Influence of Hygroscopic Materials on the Fluctuation of Relative Humidity in Museums Located in Historical Buildings     

C. Ferreira  V. P. de Freitas 《文物保护研究》2020,65(3):127-141

ABSTRACT

The preservation of artefacts in museum collections is profoundly affected by fluctuations in temperature and, especially, relative humidity (RH). Since the late nineteenth century, many studies have been carried out on the best way to control hygrothermal conditions. In old buildings located in maritime temperate climate zones (such as Portugal) with strong thermal inertia, and which have low ventilation rate (relative to the volume and number of visitors), daily and seasonal hygroscopic inertia may help to assure the maintenance of RH stabilization conditions. The use of expensive active systems may be minimized through the passive behaviour of internal finishing building materials. This work presents the results of an experimental laboratory study conducted in a flow chamber to demonstrate the enormous potential of hygroscopic materials in stabilizing interior relative humidity. Based in these results and in-situ monitoring in a museum housed in a building, located in Porto, with a typical construction of the 1950s (granite masonry and reinforced concrete slabs), a numerical analysis was done to quantify the influence of hygroscopic materials in stabilizing the interior relative humidity.  相似文献   

流动人口:社会体育的新课题--来自调研中的思考   总被引：17，自引：0，他引：17

体育从来都不是游离于社会而孤立向前发展的，社会的每一重大进步，几乎都可以在体育中找到它所带来的积极“产物”。同样，社会在发展过程中所出现的社会问题，也将会以不同的方式折射到体育中来，“流动人口”带给社会体育的挑战正是这一折射的反映。本的思考，缘起于调研中的一组数据，随后由潮起潮涌的今日之民工流动，引伸出本的主题——“流动人口：社会体育的新课题”，并围绕主题阐述了流动人口给城乡体育带来的挑战，以及应对挑战的对策和建议。  相似文献   

太极拳对老年人心肺机能的影响   总被引：16，自引：0，他引：16  

梁永文 《体育学刊》2001,8(4):64-65

通过系统观察、测试部分长年参加太极拳练习者和无训练者在完成定量负荷运动前后心肺功能指标变化,发现长期进行太板拳练习的老年人心脏泵血功能、心肌收缩机能、肺活量均显著优于普通人,表明长年从事太极拳运动对促进老年人心肺功能的改善具有积极作用,为老年人参加太极拳运动提供了可靠的实验依据.  相似文献   

学校体育是社区体育发展的依托   总被引：7，自引：0，他引：7  

郭琼珠黄景东  林群勋 《福建体育科技》2004,23(3):57-60

我国社区体育建设还处于初级阶段,体育场地设施、体育师资、体育管理人才等资源比较匮乏,许多因素制约了社区体育建设发展的步伐。而学校体育场地设施和师资力量等比较丰富,且没有得到充分的开发利用,学校体育资源浪费现象普遍存在。现阶段大力推进社区体育的建设和发展,提高全民健康水平,还需要依托辖区内学校丰富的体育资源来促进社区体育的发展。  相似文献
