In this article, we argue for the usefulness of relational event network analysis to study online communication networks. Unlike other network analytic techniques that require online communication data to be summarized prior to analysis, relational event network analysis uses un-summarized time-stamped data to track the dynamic evolution of communication networks. To illustrate, we use relational event network analysis to analyze the evolution of a communication network within the virtual world Second Life. Results suggest that there are different patterns of communication among nonfriends and friends within the network. Nonfriends tend to communicate with those they have communicated with in the past, reciprocate communication, and close communication triads. Friends tend not to communicate with those they have communicated with in the past, instead preferring to reciprocate communication and close triads. We discuss implications for the study of online communication and identify directions for future research using relational event network analysis. 相似文献

Since the 1970s, communication researchers have utilized social network analysis to understand mass, health, organizational, and interpersonal communication. This article introduces communication researchers to a new class of social network analysis methods, exponential random graph (p*) models. This new method represents the latest advancement in social network methodology and will enhance the trajectory of social network research in the communication discipline. The benefits of this class of models include allowing for the simultaneous estimation of attribute and structural parameters, accounting for the interdependent nature of network data, and retaining the complexity of network observations throughout the analysis. An example analysis using data from Shumate, Fulk, and Monge (2005) is provided to illustrate the potentials of exponential random graph modeling. Five different social network software programs capable of the analysis discussed in this article are introduced with regard to their respective benefits. Finally, a brief tutorial based on data from Palazzolo (2005) is given on how to conduct an ERGM analysis using the PNET software program. 相似文献

This experiment integrated theory from multiple domains to examine how aspects of news coverage of the Affordable Care Act (ACA) and differences in participants’ cognitive and emotional contingent conditions interact to shape attitudes and behavioral intentions toward health care legislation. Using a sample of uninsured young adults (N = 1,056), we tested an affective mediation model, which assessed the mechanisms through which media frames, exemplar case studies, and individual predispositions affect this type of news consumer. Results demonstrate the complicated pathways through which emotions mediate the effects of news coverage of ACA based on political predispositions, the need for orientation toward the health care issue, and the influence of equivalency framing in the form of example cases. These findings contribute to a more nuanced explanation of the causal mechanisms underpinning framing effects of public policy news coverage on an understudied population. The need for further examination of emotion along with cognition when investigating framing effects of public policy news is discussed, and the importance of exemplar cases as a significant manifestation of the effects equivalence framing is highlighted. 相似文献

This paper examines the columns of Ian Mayes, the first Readers' Editor of The Guardian, and of Daniel Okrent, the first Public Editor of The New York Times, to provide an empirically grounded and theoretically informed analysis of the emergent role of newspaper public editors. To do this, the paper positions the emergence of public editors as part of a wider trend towards the adoption of mechanisms of media accountability, and engages with academic literature that has positioned this trend within an emergent paradigm of “media governance”. The empirical dimension of the paper is grounded in quantitative and qualitative analysis of columns written by Mayes and Okrent during their tenure as public editors at the two newspapers, as well as key organisational documents. The findings of the data analysis suggest that, in the context of debates around media accountability and governance, there is a need to consider forms of governance such as public editors in the context of broader social and organisational concerns with declining trust, managing corporate risk and providing external demonstrations of legitimacy, and a renewed and targeted emphasis on journalistic professionalism. 相似文献

ABSTRACTToday’s most pressing scientific problems necessitate scientific teamwork; the increasing complexity and specialization of knowledge render “lone geniuses” ill-equipped to make high-impact scientific breakthroughs. Social network research has begun to explore the factors that promote the assembly of scientific teams. However, this work has been limited by network approaches centered conceptually and analytically on “nodes as people,” or “nodes as teams.” In this article, we develop a “team-interlock ecosystem” conceptualization of collaborative environments within which new scientific teams, or other creative team-based enterprises, assemble. Team interlock ecosystems comprise teams linked to one another through overlapping memberships and/or overlapping knowledge domains. They depict teams, people, and knowledge sets as nodes, and thus, present both conceptual advantages as well as methodological challenges. Conceptually, team interlock ecosystems invite novel questions about how the structural characteristics of embedding ecosystems serve as the primordial soup from which new teams assemble. Methodologically, however, studying ecosystems requires the use of more advanced analytics that correspond to the inherently multilevel phenomenon of scientists nested within multiple teams. To address these methodological challenges, we advance the use of hypergraph methodologies combined with bibliometric data and simulation-based approaches to test hypotheses related to the ecosystem drivers of team assembly. 相似文献

The role of third-party mediation and face and favor in executive–legislative relations and conflict
Yi-Hui Huang 《亚洲交流杂志》2013,23(3):239-263
This paper explores the role of third-party mediation in particular and the extent to which four conflict management strategies, i.e., third-party mediation, integration, distribution, and avoidance in general, exist and affect conflict resolution in the Taiwanese government's executive–legislative relations. Additionally, third-party mediation mianzi (face) and renqing (favor) in relation to Chinese culture are explored. Two independent samples were included in this study. The first included 235 legislative members and their assistants working within the legislative branch. The second included 301 legislative liaisons from the executive branch in Taiwan. The results indicated that four conflict strategies had been used in legislative–executive relations, namely integrative, distributive, non-confrontational, and third-party mediation, with mediation being the least frequently used. Third-party mediation, across two independent samples, was shown to have the strongest correlations with non-confrontation/avoidance versus integration and last distribution. Face and favor, then, were first associated with distribution, then third-party mediation, avoidance, and finally integration. 相似文献

Communication research based on social cognition draws heavily from dual process models such as the heuristic-systematic model. Both heuristic and systematic processing are said to be aided by quick rules of thumb or mental shortcuts called heuristics. However, the operationalization of heuristics is quite problematic because their use in decision-making is not directly measured. Scholars claim the operation of specific heuristics in specific situations, based often on clever experimental evidence. We propose a methodological framework that calls for both manipulation and measurement of heuristics in order to offer more direct evidence of their operation. We first review different existing approaches in the literature for operationalizing heuristics. We then discuss our approach and describe the application of moderated mediation to analyze the resulting data. We conclude with a study idea and simulated data that illustrate how our proposed design and analysis framework could be applied in communication research. 相似文献

The primary goal of the present study is to discover new drug treatments by topology analysis of drug associations and their therapeutic group network. To this end, we collected 19,869 papers dated from 1946 to 2015 that are related to autism treatment from PubMed. We extracted 145 drugs based on MeSH terms and their synonyms (the total number is 6624) within the same ATC classification hierarchy and used them to find drug associations in the collected datasets. We introduced a new topology-driven method that incorporates various network analyses including co-word network, clique percolation, weak component, pathfinding-based analysis of therapeutic groups, and detection of important drug interaction within a clique. The present study showed that the in-depth analysis of the drug relationships extracted from the literature-based network sheds new light on drug discovery research. The results also suggested that certain drugs could be repurposed for autism treatment in the future. In particular, the results indicated that the discovered four drugs such as Tocilizumab, Tacrolimus, Prednisone, and Sulfisoxazole are worthy of further study in laboratory experiments with formal assessment of possible effects on symptoms, which may provide psychologists, physicians, and researchers with data-based scientific hypotheses in autism-drug discovery. 相似文献

Determining what factors predict media learning is an important avenue of research for the field of mass communication. The present study provides a comparative investigation of two models of media learning: the cognitive mediation model and the information utility model. Participants (N = 1,076) read a news article related to scientific discoveries relevant to cancer prevention and responded to all constructs of the two models. Recognition and comprehension were used to measure knowledge acquisition. Results generally support previous predictions of each model, though predicted variance remains small. In addition to testing the existing models, a modified cognitive mediation model using a key construct related to information utility—perceived relevance—was tested. The refined cognitive mediation model offered a more nuanced understanding of certain causal mechanisms but did not result in a meaningful change in predictive power of the model. Implications of the theoretical comparison and integration are discussed. 相似文献

The current research explored a new social movement network in the northeastern United States in order to build on past research concerning a Resistance Performance Paradigm (RPP). In particular, I found that the network in the northeastern community displayed characteristics of RPP but did not construct a “multiplex” of coordinated resistance as had emerged in past RPP research. I interviewed 20 activists in order to assess how the northeastern network was different from previous RPP research, and whether such differences accounted for the lack of a multiplex of coordinated resistance. The interviews revealed that the network was fractured over (a) what issues to address and (b) how to approach/protest any such issues. Further data analysis revealed that the fractures stemmed in part from activists' uncertainty about a listserv used by all of the activists in the network. Such findings constitute an additional characteristic of RPP: the capacity of a network to efficiently circulate narratives to all points in a network. 相似文献

We examined the role of parental media mediation in the relationship between media violence and adolescents’ ADHD-related behaviors. Survey data from 1,017 adolescents (10–14 years) show that parents can play an important role in this relationship, depending on the media mediation strategies that they use (i.e., restrictive or active mediation) and how they apply these strategies (i.e., in a controlling, inconsistent, or autonomy-supportive way). Our findings support the notion that contextual factors are critical in understanding media effects, and provide directions for how parents can manage their adolescents’ violent media use, and possibly by extension, their ADHD-related behaviors. 相似文献

In this rejoinder, I argue that explanations made in Croucher (2015) [Further development of integrated threat theory and intergroup contact: A reply to Aberson (2015). Communication Monographs] for odd results are not theoretically relevant, represent highly unlikely outcomes inconsistent with the reporting in Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62], and are likely not the result of a unique sample or target. First, I demonstrate that arguments regarding negative contact are not applicable to the present work as Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62] measured positive contact. Next, I note that arguments regarding use of pairwise deletion are theoretically possible, but practically would represent extreme situations that suggest substantial issue with the dataset. I also note that Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62] made no mention of the amount of missing data or approaches used to deal with missing values. Finally, I highlight that the use of an adult sample and Muslim targets is by no means unique within the integrated threat literature and that findings from studies using similar samples and targets remain at odds with Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62]. 相似文献

We investigate the ways young children’s use of mobile touchscreen interfaces is both understood and shaped by parents through the production of YouTube videos and discussions in associated comment threads. This analysis expands on, and departs from, theories of parental mediation, which have traditionally been framed through a media effects approach in analyzing how parents regulate their children’s use of broadcast media, such as television, within family life. We move beyond the limitations of an effects framing through more culturally and materially oriented theoretical lenses of mediation, considering the role mobile interfaces now play in the lives of infants through analysis of the ways parents intermediate between domestic spaces and networked publics.
We propose the concept of intermediation, which builds on insights from critical interface studies as well as cultural industries literature to help account for these expanded aspects of digital parenting. Here, parents are not simply moderating children’s media use within the home, but instead operating as an intermediary in contributing to online representations and discourses of children’s digital culture. This intermediary role of parents engages with ideological tensions in locating notions of “naturalness:” the iPad’s gestural interface or the child’s digital dexterity. 相似文献
