Considering the debate over U.S. immigration reform and the way digital communication technologies increasingly are being used to spark protests, this qualitative study examines focus group discourse of immigration activists to explore how digital media are transforming the definitions of “activism” and “activist.” Analysis suggests technologies are perhaps pacifying would-be activists, convincing them they are contributing more than they actuall…
Coverage of the Iraq War in the United States, Mainland China, Taiwan and Poland
Walter Lippmann's description in Public Opinion of the news media as the bridge between “the world outside and the pictures in our heads” is particularly apt for the two goals of this study: exploring a new perspective in agenda-setting theory grounded in network analysis, which, in turn, provides the setting for a comparative analysis of the Iraq War news coverage in newspapers of the United States, Mainland China, Taiwan and Poland. Exploring c…
Whose Story Wins on Twitter
The South China Sea dispute is one of the most complicated geopolitical issues of the twenty-first century. While this international conflict revolves around military and economic disputes, in today’s information age international politics also hinges on how each country presents the dispute in the news and whose “story” wins. Based on the Network Agenda Setting model, this study analyzed the news coverage in three involved countries—China, the P…
Adopt or Not and Innovation Variation
Policy innovation and diffusion literature mainly focuses on the decision to adopt a new policy, while ignoring the differences among new policies. This study divides the decision-making process of policy innovation diffusion into two phases: in the “innovate or not” phase, governments make the decision to adopt or reject the new policy, while “how to innovate” is the process by which governments formulate specific content for the new policy. A d…

Effects of Emotional Labor Engagement on Job Burnout
Over the past decades, research on emotion in journalism has been under-researched since it was seen in opposition to objectivity and legacy journalism. While some studies have identified the dynamic role of emotion in mediating relationships among news content, audience, and reporter, the existing literature paid less attention to journalists’ emotional experience at work and its impact. Drawing on Grandey’s model of emotional management at work…

Singing competition reality shows have gradually come to dominate the mainland Chinese TV program market. This study explores the gratifications that Chinese audiences seek from watching such shows. An analysis first reveals that the most salient gratifications sought are ambition, suspense, social interaction, and high production quality. Second, narcissism significantly enhances the gratifications that audiences seek in viewing such shows. Thir…
Digital Rage
The concept, 'White Rage,' has previously been used to describe the way Whites have historically responded to Black advancement with policies and practices designed to quietly disrupt the progress Blacks had been making. White rage is typically subtle, masking its true intent. In contrast, recent research has found that the covert, subtle expressions of racism that are so normal in most mainstream spaces may be less common in internet-based commu…
The Values of Print
This paper examines print affordances based on Gibson’s conceptualization. We conducted semi-structured in-depth interviews with long-time newspaper subscribers to understand three kinds of affordances: physical affordances germane to the print medium, perceived affordances utilized by experienced readers, and relational affordances generated in the transactional process of news consumption. We argued that affordances offer a theoretical lens to …

A-Stratified Methods Combining Item Exposure Control and General Test Overlap in Computerized Adaptive Testing
摘要
Cognitive Diagnostic Assessment with Different Weight for Attribute
An attribute weight calculation method which used a Bayesian network and the least squares distance method was proposed to assign different weights to different attributes in cognitive diagnosis. This method is independent of any specific cognitive diagnostic models, so it is practicable to consider attribute weight not only in the models with explicit expression but also in item response theory-based cognitive diagnostic methods. Simulation stud…
