The Interaction of Issue and Image Frames on Political Candidate Assessment     

Sean Luechtefeld  Adam S. Richards 《Communication Studies》2016,67(1):20-36

This study examined the combined effect of character and policy coverage about a political candidate in news media on voters’ evaluations and thoughts about the candidate. A 2 (issue coverage: present/absent) × 2 (image coverage: present/absent) between-subject factorial experiment was conducted whereby participants (N = 134) read a version of an editorial article that varied in the coverage of a candidate’s character and policy positions. Results indicated that issue and image coverage, each in isolation, enhanced perceptions of the candidate’s image strength and issue strength. However, issue and image coverage when presented in combination compared to in isolation did not enhance perceptions of the candidate and in some cases hindered perceptions of candidate strength. When both coverage types were present, issue coverage dominated image coverage when participants formed image evaluations, whereas image coverage dominated issue coverage when they formed issue evaluations. Similar findings resulted for issue- and image-relevant thoughts. Implications about the effects of multicoverage political messages are discussed.  相似文献   

State-of-the-art in biomedical literature retrieval for clinical cases: a survey of the TREC 2014 CDS track     

Kirk Roberts  Matthew Simpson  Dina Demner-Fushman  Ellen Voorhees  William Hersh 《Information Retrieval》2016,19(1-2):113-148

Providing access to relevant biomedical literature in a clinical setting has the potential to bridge a critical gap in evidence-based medicine. Here, our goal is specifically to provide relevant articles to clinicians to improve their decision-making in diagnosing, treating, and testing patients. To this end, the TREC 2014 Clinical Decision Support Track evaluated a system’s ability to retrieve relevant articles in one of three categories (Diagnosis, Treatment, Test) using an idealized form of a patient medical record. Over 100 submissions from over 25 participants were evaluated on 30 topics, resulting in over 37k relevance judgments. In this article, we provide an overview of the task, a survey of the information retrieval methods employed by the participants, an analysis of the results, and a discussion on the future directions for this challenging yet important task.  相似文献

Facial Similarity Mitigates the Persuasive Effects of Source Bias: An Evolutionary Explanation for Kinship and Susceptibility to Influence     

Adam S. Richards  Dale Hample 《Communication monographs》2016,83(1):1-24

This research examined how the interaction between a source's facial similarity to message targets and communicated bias affects audience persuadability. We used an evolutionary explanation to hypothesize that biased sources would elicit less favorable attitudes than unbiased sources for dissimilar sources, but that this difference would be absent for similar sources. Predictions were supported by results from a 2 (facial similarity) × 2 (source bias) experiment, in which an unrecognizable percentage of participants' photographs (n = 94) was digitally morphed with a source's face to act as a kinship cue. Further, structural equation modeling demonstrated a direct effect of facial similarity on attitude independent of mediation by source liking and appraisals, providing further evidence that susceptibility to influence from facially similar sources may have evolutionary origins.  相似文献   

The influence of race on attitudes about college athletics     

James N. Druckman  Adam J. Howat  Andrew Rodheim 《Sport in Society》2016,19(7):1020-1039

The questions of whether college student-athletes should be paid and/or allowed to unionize have generated a wide-ranging national debate. Public opinion on these issues is starkly divided along racial lines, with African-Americans dramatically more supportive than non-African-Americans. We posit that the race gap stems from fundamentally distinct mindsets. African-Americans view pay for play and unionization as mechanisms to enhance educational experiences and hence as a form of affirmative action. Non-African-Americans, in contrast, focus on the extent to which they enjoy the consumption value of college athletics. We present results from a nationally representative survey experiment that supports our expectations. We also find that non-African-Americans can be swayed to employ a more race-based lens on these issues, although this re-framing does not diminish the attitudinal race gap. We conclude with a discussion about race, sports and public opinion.  相似文献
