Information sharing is considered an important approach to increasing organizational efficiency and performance. With advances in information and communication technology, sharing information across organizations has become more feasible. In the public sector, government agencies are also aware of the importance of information sharing for addressing policy issues such as anti-terrorism and public health. However, information sharing can be a complex task. Identifying factors that influence information sharing is critical. In the literature, research in information sharing focuses on the interpersonal, intra-organizational, and inter-organizational levels. This paper reviews the current information-sharing research, discusses the factors affecting information sharing at the three levels, and provides summative frameworks. These frameworks provide a means to discover future research opportunities, and a systematic way for practitioners to identify key factors involved in successful information sharing.  相似文献

This study reports a droplet-based microfluidic device for on-demand electrostatic droplet charging and sorting. This device combines two independent modules: one is a hydrodynamic flow focusing structure to generate water-in-oil droplets, and the other is the two paired-electrodes for charging and sorting of the droplets. Depending on the polarity on charging electrodes, water-in-oil droplets can be electrostatically charged positively or negatively, followed by automatic real-time electric sorting. This approach will be useful when preformed droplets, with a positive, a negative, or with no charge, need to be manipulated for further on-chip droplet manipulation.  相似文献

Using statewide survey study data collected from more than 5,000 community college students, this study examined the impact of a preengineering curriculum on students' self-efficacy level after they entered rural community colleges. Project Lead The Way (PLTW), is a project-based learning curriculum for middle and high school students that strives to create a path to college and career success in STEM-related fields. In this article, the authors focused on comparing the probability of rating high self-efficacy among 86 community college students who participated in PLTW with students with no PLTW experience. The findings indicated that PLTW students have significantly lower probability of rating high self-efficacy compared to their non-PLTW counterparts. It might be that PLTW students rated their self-efficacy by comparing with a group of their close peers, who might be a group of academically high-ability students. This study provides implications for the unique, perhaps unintentional, peer effects of the project-based learning curriculum on the self-rating of students' self-efficacy. The findings highlighted the secondary-postsecondary nexus on STEM education, especially the importance of secondary programs that could positively influence the STEM educational pathways for community college students.  相似文献

Approaches to environmental education which are engaging with place and critical pedagogy have not yet broadly engaged with the African world and insights from Africana Studies and Geography. An African-centred approach facilitates people’s reconnection to places and ecosystems in ways that do not reduce places to objects of conquest and things to be exploited for profitability and individual gain. Such an approach offers effective critiques of settler coloniser perspectives on the environment and deeper understandings of the relationship between worldview and ecologically sensitised education. Through examples from Africana Studies and Geography, this article provides an introduction to how an African-centred approach can contribute to the development of a Land Education perspective and improve college-level environmental education.  相似文献

Thirty educable mentally retarded (EMR) children were presented an item selection task to assess their sensitivity to orthographic structure in printed English words. Analyses of performance indicated that EMR children do acquire implicit knowledge of orthographic rules and that this ability is related to the development of reading skills.  相似文献
