目前,学术界多开展引用动机和引文功能的相关研究,但对于引用偏好等引用行为却关注较少。基于Taylor的信息使用环境理论,本研究采用参考文献分析方法,全面揭示了施引者引用行为的特征和影响因素。研究将信息使用环境理论中的前三类要素分别通过学者特征、组织环境及论题进行定义,采用参考文献分析法提取第四类要素;随机抽取论文样本,针对上述四类特征进行编码并通过统计分析探讨影响施引者引用行为的因素。研究发现:学者的年龄、性别、教育水平、学术年龄、职业角色、职称、所属机构的类型和层次以及所从事的研究主题和类型,都能对质量、语种、数量、信息资源类型、论文新旧的引用偏好产生显著影响。研究表明:信息使用环境理论和参考文献分析法在引用行为研究中具有适用性。表4。参考文献47。  相似文献

Libraries play a critical role in enhancing the learning landscape of the schools they support. In order for any library to become a powerhouse and a community meeting place, all library team members need to align with the library's vision, own it and begin to add their own strengths and talents purposefully. This article explores practical strategies for developing a visionary team, including supportive leadership, daily stand-up meetings, weekly staff meetings, special-focus teams, rostering and the “five conversations” approach. These effective strategies can be implemented across a broad range of library workforce contexts in order to ensure the most effective workforce teams are built.  相似文献

Libraries have been the key to preserving culture and historic legacy for centuries. One such treasure cataloged in The Pennsylvania State University (Penn State) Libraries is a collection of over 33,000 Sanborn? Fire Insurance Maps. Originally kept safe in metal drawers, the library has embarked on a journey to digitize this abundance of information, combine it with other media such as photographs, and make it accessible through a web interface. Inspired by these efforts, we accessed this information and took it to the next level. Using state of the art 3D modeling and immersive technologies, we created a historic 3D model and immersive experiences of Penn State, exemplarily for the 1922 campus. The resulting experiences can be accessed through the web but also through head mounted displays (HMDs) and mobile phones in combination with VR viewers such as the Google Cardboard. Additionally, they can be used anywhere in the world or on the campus itself as a way to enable remote and in situ experiences and learning. Immersive experiences let us connect to the past, the present and the future, and as such offer value to digital cultural heritage efforts.  相似文献

In this contribution, we develop a new approach to explore the process of knowledge transition from discovery-oriented science to technological fields, via applications-oriented research, including a mediator set. This trajectory is referred to as the D-A-T trajectory. It is shown how it can be constructed and measures are proposed to characterize the relational strength among different environments (discovery oriented research, applications-oriented research and patents) and the speed of evolution. Our approach is illustrated by a case study of three fundamental restriction enzymes articles. Among other results we found that 387 patents cited 124 of the 988 articles (a share of 12.55%) in the mediator set. Defining the non-patent references (NPR) transition rate as the number of citing patents divided by the number of articles in the mediator set yields a value 0.392. Our results suggest that the D-A-T path acts as a backbone and reveals important “invisible contributions” of an original scientific work during its evolution from discovery oriented research to outside academia. Our contribution provides a useful tool for bridging the existing gap in detecting the transition of knowledge between science and technology.  相似文献

The aim of this study was to investigate the frequency of child physical maltreatment (CPM) in children with autism aged 2–5 years in Henan province (China), and to explore the risk factors for severe CPM in these children. This cross-sectional study was performed at the Psychology Clinic of the Third Affiliated Hospital of Zhengzhou University between September 2012 and September 2013 with 180 parents of children with autism. Children and parents had no history of any cognitive therapy. The childhood autism rating scale (CARS) was used to evaluate the severity of autism in children. Data on parental CPM during the past 3 months were collected from parental self-reporting. Logistic regression was used to investigate the risk factors of severe CPM. CPM was self-reported by 88% of the parents of children with autism. One hundred and fifty four of these cases were in the minor CPM group (86%) and 64 in the severe CPM group (36%). Most cases of severe CPM were unlikely to have caused injury. Univariate analyses showed that child's age (p = .018), age started to speak (p = .043) and CARS score (p = .048) were associated with severe CPM. Child's age (p = .011) and CARS score (p = .041) were independently associated with severe CPM. The risk of severe CPM increased with age and CARS score. Our findings showed that CPM is widespread in families of children with autism in Central China and more knowledge should be provided to parents of children with autism, particularly in cases of severe autism (those with high CARS scores).  相似文献

幼儿独立性是幼儿自我发展的内在动力,是个性品质的基础和关键。3-6岁是幼儿自主性、独立性迅速发展的时期,而幼儿园是培养幼儿独立性的重要场所。幼儿独立性对幼儿未来的发展有着重要的影响。幼儿园的环境分为精神环境和物质环境两种,因此要从这两个环境中培养和促进幼儿独立性的发展。  相似文献

This paper examines the long-run relationship between school bullying exposure and later adult health using a nationally representative household survey data from China. Our results show that victims are more likely to have low self-reported health, chronic diseases, physical functional limitations, and mental health problems even after several decades. The negative health consequences are more concentrated on the disadvantaged who come from low-income households or lack family support. The main findings are also consistent with qualitative evidence of our online survey.  相似文献

大学生心理健康是政府关心、学校担心、家长揪心的一个非常重要的问题。现在刚入学的大学生绝大部分是90后,由于他们生活、成长的家庭、社会、教育环境不同,与以往大学生存在一些差异,必须引起我们教育工作者的重视和思考。  相似文献

作为一项系统工程,物流系统对环境的扰动主要体现在包装、运输、储存保管、装卸搬运、流通加工、配送以及物流信息等方面。扰动的关键原因在于现实中粗放的物流模式、不合理的物流规划、物流标准化的缺乏等因素的影响。现实生活中,环境系统及其环境问题也有可能通过经济系统和法律体系等途径来制约和影响着物流系统的有序运作。  相似文献

《木兰诗》是南北朝时期的代表作,它将木兰这个女子形象置于战争的环境中,置于个人、家庭和国家利益的矛盾交织中来展现其性格以及这种性格所包含的文化内涵。北魏的战争环境所导致的经济破坏、人口男女比例失调是《木兰诗》产生的社会背景;北方诸民族的尚武粗犷的民风民俗是《木兰诗》产生的文化环境;"木兰无长兄的实际情况导致了木兰具体的出征行为。然而,当时的人们并没有认识到木兰形象所可能包含的新的人生价值观,最终将其纳入了中国传统文化的行为规范之中。  相似文献
