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

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

Communication scholars have studied how organizations socialize new employees in breadth, but we know less about how employees adapt to multiple roles rather than just one position. With the rise of rotational programs, which introduce newcomers to several different jobs within a brief time, socialization theory should be expanded. This study focused on people’s experiences in rotational programs to provide a more accurate picture of this complex socialization process. Longitudinal, qualitative data from employees during their first and second job rotation revealed that such employees’ socialization differs from traditional employees’ experiences. The results suggested a Model of Rotational Socialization that more accurately portrays the socialization process by accounting for the contrast between role and organizational socialization. 相似文献

The present study was designed to investigate the relationships between role strains following the transition to secondary school and academic achievement. Academic engagement was hypothesized to mediate between role strain and achievement. The sample consisted of 749 students in their first year of secondary school. Four types of role strain were investigated: parent, teacher, school and peer. Parent and teacher role strains appeared to be negatively associated with academic achievement, as mediated through academic engagement. Parent and school role strain were directly and negatively associated with achievement. Results are discussed in the light of parenting practices and the developmental mismatch hypothesis. 相似文献

教育技术是一项解决教育问题的系统技术,可用于推动教育、教学的各个层面上的改革。但二十多年来,由于认识受限,定位不当,我国这一领域的工作偏重于硬件设施建设与服务、教育媒体制作、教学方法改革等方面,且这些活动大部分在战术层面上开展,教育技术没有发挥更大的作用。当前,我们应关注在战略层面上实施教育技术,追求“效果、效率和效益”,即教育绩效,这是我国穷国办大教育的国情所要求的。战略优先,战术配合,战略战术互动,促进教育整体改革,落实科学发展观,这应成为信息化进程中我国教育技术高起点新发展的指导思想,成为我国教育技术学科知识体系构建研究的基本思路。用教育技术引领教育改革,在宏观层面上应重视需要的评估和系统规划,确保“做对的事情”;在中观层面上要推广教学系统设计,在微观层面上要加强对研究成果的运用,确保“把事情做对”。目前我国教育技术界电教人员或计算机科学人员的工作仅是教育技术的一个组成部分,教育技术也是各级教育管理者和广大教师的共同事业。 相似文献

体育校本课程开发赋予体育教师新的使命和角色身份, 为了使体育校本课程开发能够有效地进行,体育教师必须完成从“消费者”到“生产者”、从“教书匠”到“研究员”、从“点莱者”到“菜单提供者”、从“施教者”到“指导者”、从“独奏者”到“协奏者”等5 个方面的角色转换。 相似文献

客家籍大学生性别角色研究 总被引:3,自引:0,他引:3
本研究采用钱铭怡等人编制的大学生性别角色量表 ,对 5 3 2名嘉应学院大学生进行测试。结果发现 :客家籍大学生的性别角色类型分布结果与钱铭怡等人的研究非常相似 ,与广州地区大学生的调查研究结果也无明显差异。这表明所用量表信度、效度较高 ,同时也说明客家籍大学生的个体社会化发展与大学生群体的发展是一致的。本研究结果表明 :客家籍与非客家籍大学生性别角色类型分布无显著差异 ,本科生与专科生、文科生与理科生在性别角色类型分布上均无显著差异 相似文献
