[目的/意义]旨在分析协同搜索用户在信息搜索任务过程中的交流内容与模式,从而理解协同搜索用户的关注重点与搜索过程。[研究设计/方法]基于书籍交互检索平台(CLEF-Social Book Search)设计实验,共招募18名被试完成两种搜索任务,通过录音记录对话并对其进行编码和分析,总结交流内容特征和模式。结合任务类型、认知类型组合、服务器记录的搜索交互行为日志以及问卷收集的搜索体验进行了探索分析。[结论/发现]从交流内容上看,协同搜索用户主要理解与评判书目信息、商讨搜索任务计划;比起认知类型不同的用户,相同认知类型的用户在操作交互方面交流更多,在评判决策方面交流较少。交流模式依据讨论内容比重可分为理解评判型、评判主导型、均衡交流型三种,评判主导型用户的任务完成满意度最高。[创新/价值]协同搜索用户的交流反映出搜索过程中需要与同伴商讨协同的焦点,也是需要系统提供协助的重点,给协同搜索系统设计提供一定参考。本研究针对协同搜索的交流内容设计的编码系统对相关的协同交流研究也有借鉴意义。 相似文献

AbstractDiversity literary awards and other sources were used to create a list of high-quality titles written by and about underrepresented groups. This list was used to assess the diversity and inclusiveness of the library collections of a land-grant university in the Pacific Northwest and compare it to peer institutions. Gaps in the collection and acquisition processes were identified and will be used to improve the processes to increase the number of diverse titles added to the library’s collections. 相似文献

Managed care poses numerous opportunities and challenges for today's health care organizations and their employees. This article investigates the ways that hospital nurses develop and make sense of their professional roles and organizational environments in a changing and often uncertain managed care setting. The case study approach used in this research combined qualitative methodologies to gain a rich, detailed, and contextual understanding of nurses' work roles and organizational experiences. After an analysis of interviews with 24 nurses and observations of nurses' communicative activities on one inpatient unit, the complexity of sensemaking and role development in a managed care environment is considered. Conclusions are then drawn regarding the theoretical and pragmatic implications of nurses' communicative processes, as they attempted to develop and understand their roles in a changing organizational context. 相似文献

There is an increasing interest in linking character education programs with social and academic outcomes. The Child Development
Project (CDP) is a character education program that promotes academic and social growth in teachers and students. This theory-driven
evaluation employed a quasi-experimental design with matched control schools. School personnel participated in an intensive
professional development process to learn the CDP model. Performance measures included state-mandated achievement measures,
teacher self-assessment reports, and student attitudes and outcomes. Results yielded support for the CDP model as a strategy
to improve social and, if properly implemented, cognitive outcomes in students; the model also improved teacher self-assessment
and provided information that may facilitate professional growth about school collegiality. Implications for policy and practice
will be discussed. 相似文献

Chaos theory, informational needs, and natural disasters 总被引:2,自引:0,他引:2

This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning. 相似文献
