Tracking user-role evolution via topic modeling in community question answering     

Chaogang Fu 《Information processing & management》2019,56(6):102075

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   

Role Development in the Managed Care Era: A Case of Hospital-Based Nursing     

Julie Apker 《Journal of Applied Communication Research》2001,29(2):117-136

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

Extending Humor Enactment Research     

Melanie Booth-Butterfield  Penka Kanjeva 《Communication Research Reports》2018,35(4):356-362

Humor orientation (HO) is an individual difference variable that influences production and delivery of humorous communication. Prior research indicates that people who score higher on HO enact humor more frequently and effectively, which in turn leads to more benefits and advantages in a variety of social and psychological outcomes. Research reported here extends this line of analysis with HO for its relationship to a broad gauge measure of benefit, satisfaction with life, extending HO into understudied domains. This study compared Bulgarian adults (n = 100) to several American samples. Primary findings were that Bulgarians were similar to American samples overall but scored consistently higher than Americans on satisfaction with life (SWL). HO and SWL are correlated (r = .27), a medium effect size.  相似文献   

定向行走课程与教学专业能力研究     

杞昭安 《现代特殊教育》2020,(2):26-37

从感觉训练、概念发展、行动技能、定向系统、求助技能、安全议题、小区资源与大众运输系统七个方面选取50项能力指标,对海峡两岸64名担任定向行走课程的教师进行问卷调查。调查结果显示:大多数被调查者认可这50项能力指标;定向行走教师对自己的课程与教学专业能力认可度多为中等,需要进一步作培训。同时发现,在定向行走课程与专业能力各向度的重要程度上,海峡两岸定向行走教师的认知有显著差异,各向度胜任程度的差异更加明显;而定向行走教师的年龄对定向行走课程与教学专业能力在重要程度和胜任程度上并没有显著差异;海峡两岸担任定向行走课程的教师,多数认为有培训的必要。建议将重要性在3.5以上的题目编制为《定向行走专业能力检核表》;将定向行走专业能力胜任程度在3.5以下的向度作为定向行走师资培训的参考。  相似文献   

I’m New…Again: Reconceptualizing the Socialization Process Through Rotational Programs     

Stephanie L. Dailey 《Communication Studies》2016,67(2):183-208

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
