高校大型科学仪器开放共享的现状分析与对策研究

总结过去30年高校仪器设备共享工作取得的建设成果,分析现阶段高校大型科学仪器共享工作面临的一些实际困难,提出了当前条件下的共享策略。即;国家应通过增加经费投入、完善拨款机制来保障设备资源的共享运行和优化配置;地方政府应通过完善服务平台、搭建共享桥梁、激励供需双方来推进区域内的共享环境建设;高等学校需通过技术队伍培训、完善激励机制以强化校内共享基础条件建设。通过3方面共同作用,逐步完善机制,推进有效共享,提高资源效益。     

小城镇建设适度用地探析

小城镇是介于城市与农村之间的居民点,它既有城市密集的用地方式,又有农村低矮的建筑格局。确定小城镇的适度用地规模需要充分考虑小城镇发展的现有条件和不可预见因素;加强小城镇周边农地地价评估和改善旧镇域的投资环境是从节流和开源两个方面促使小城镇集约用地的有效措施;科学制定土地管理制度和提高土地管理执行效率,能促进小城镇土地的集约利用。

IT engagement as a blessing and a curse? Examining its antecedents and outcomes in organizations

Information technology (IT) engagement is defined as a need to spend more time using IT. Practice-based examples show that IT engagement can have adverse effects in organizations. Although users can potentially get more work done through IT engagement, observations show that the users might jeopardize their well-being and hamper their work performance. We aimed to investigate this complexity in the research on IT engagement by examining its potential antecedents and outcomes in organizations. Considering the potentially mixed outcomes, we developed a model to examine the effects of IT engagement on personal productivity and strain. We also aimed to explain the antecedents of IT engagement by drawing on the collective expectations for IT use. In particular, we examined the extent to which normative pressure on IT use drives users’ information load and IT engagement. Finally, we sought to understand whether users’ attempts to avert dependency on IT use reduced their IT engagement. Several hypotheses were developed and tested with survey data of 1091 organizational IT users. The findings help explain the role of normative pressure as a key driver of IT engagement and validate the positive and negative outcomes of IT engagement in organizations.     

If you Build it,They Won’t Come: What Motivates Employees to Create and Share Tagged Content: A Theoretical Model and Empirical Validation

The purpose of this paper is to investigate factors influencing employees’ knowledge-sharing behavior on social tagging supported systems. Using the strong theoretical background of the well-known technology acceptance model (TAM), this paper proposes and empirically validates a model that fits the social and technical nature of social tagging tools within the public sector. The analyses in this paper were based on data collected from a large survey of more than 480 respondents working for two public organizations in the United States. The findings demonstrate a significant impact of the role of social presence in encouraging employees to create and share content. Further, there is a strong relationship between the benefits employees receive from using tagging tools and their creation and sharing of tagged content. Specifically, the following factors showed a significant impact on employees’ creation and sharing behavior, specifically their attitudes towards and intentions to create and share tags: perceived ease of use, perceived usefulness, social presence, and pro-sharing norms. For researchers, the paper offers an opportunity to further study knowledge-sharing behavior regarding social media technologies. The findings should motivate practitioners to inject these tools with a social aspect so that employees are encouraged to share content.
