Although our popular culture stereotypes relationships with in-laws as problematic, these relationships have largely been overlooked by communication researchers. In contrast to existing studies focusing on dyadic relationships, this study looked at how in-laws are assimilated into the family group as newcomers, using structuration theory to examine how routines are reproduced in families. In personal interviews, participants described how their families had assimilated newcomers or how they themselves were received into their spouse's families. A thematic analysis revealed specific communication routines that had to be adjusted upon entry of newcomers, including conversational topics, expected amount of interaction, use of joking, and conversational styles. Adjustments to these routines, although difficult to negotiate because they were not openly discussed, helped to transform the family of childhood into the family of adulthood. Structuration theory would suggest that the perceived stress in relationships with in-laws occurs because newcomers upset the comfort of families by disrupting their communication routines.  相似文献

图书馆学对象研究:审问与批判   总被引:9,自引:0,他引:9  
对图书馆学研究对象的研究重新进行审视,提出了如下几个问题:研究对象的变换何时了?问题之争有多大的必要性?研究对象到底是什么?研究对象与图书馆学成熟的关系如何?是多研究些“问题”还是多谈些“主义”?等等。对这些问题进行了分析和评判。  相似文献

本文以国外传播理论教材的译介作为视角,考察了欧美传播理论话语在中国的诠释和变异,研究了西方客观经验主义的大众传播理论如何被潜移默化地等同于传播学的过程,同时以《传播理论导引:分析与应用》为例,对我国目前传播学的教学与研究中存在的一些问题进行了探讨,提出应该进一步开阔视野、注重研究范式、重新思考传播理论的教学与应用。  相似文献

This study focused on a cohousing community's use of consensus to make a decision about surfacing a parking area. It revealed that the community's use of consensus decision making allowed the residents to balance three goals: making an appropriate decision, meeting members' needs, and maintaining the community's well-being. Reaching agreement, however, was complicated by members' value differences and discontinuity in their participation. The analysis of this case reveals three qualities characteristic of the enactment of consensus: the role of structured communication within and between group meetings, a tension between maintaining process openness and reaching decision closure, and the expectation that group members will work within the consensus process. The analysis also highlights the importance of timing in the interpretation of conflict in a consensus-oriented group and the role of process change when a group reaches the limits of members' commitment to consensus.  相似文献

Searching online information resources using mobile devices is affected by small screens which can display only a fraction of ranked search results. In this paper we investigate whether the search effort can be reduced by means of a simple user feedback: for a screenful of search results the user is encouraged to indicate a single most relevant document. In our approach we exploit the fact that, for small display sizes and limited user actions, we can construct a user decision tree representing all possible outcomes of the user interaction with the system. Examining the trees we can compute an upper limit on relevance feedback performance. In this study we consider three standard feedback algorithms: Rocchio, Robertson/Sparck-Jones (RSJ) and a Bayesian algorithm. We evaluate them in conjunction with two strategies for presenting search results: a document ranking that attempts to maximize information gain from the user’s choices and the top-D ranked documents. Experimental results indicate that for RSJ feedback which involves an explicit feature selection policy, the greedy top-D display is more appropriate. For the other two algorithms, the exploratory display that maximizes information gain produces better results. We conducted a user study to compare the performance of the relevance feedback methods with real users and compare the results with the findings from the tree analysis. This comparison between the simulations and real user behaviour indicates that the Bayesian algorithm, coupled with the sampled display, is the most effective.

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning.  相似文献

Social media have become an integral part of online news use, affecting how individuals find, consume, and share news. By applying the Theory of Reasoned Action (TRA), this study investigates the effects of motives, attitude, and intention on news-sharing behavior among German social media users (n = 333). Findings show that news-sharing attitude and subjective norms have a positive effect on news-sharing intention, which in turn has a positive effect on actual news-sharing behavior. Taken together, we see that a new media behavior in the early phases of its societal diffusion—like social media news sharing in Germany in 2015—can mainly be explained by a rational choice logic and is rooted in the motives of socializing and information seeking. This finding thus reflects the double nature of social media as a means for both information retrieval and social grooming.  相似文献
