This study examines US and South Korean journalists' use of sources and their perceptions of source credibility in covering the six-party talks on North Korea's nuclear ambitions. In particular, this study analyzes the relationship between journalists' perceptions of source credibility and the media's source use in terms of the aggregate and individual levels. Results of content analysis of US and South Korean newspapers are compared with data from a survey of US and South Korean journalists who covered the six-party nuclear talks. Government officials are dominant sources in media coverage of the talks because of their high level of accessibility and credibility. US and South Korean journalists assigned the greatest credibility to government officials of their own country. The two groups showed significant differences in their perceptions of credibility of South Korean officials, North Korean officials, Japanese officials, and Japanese experts. Moreover, this study finds that individual journalists' perceptions of source credibility were as strongly correlated with their individual use of sources as with the news media's aggregate use of sources. Implications of the findings are discussed in the context of media sociology, in particular gatekeeping. 相似文献

Participatory media are commonly used in today's society for a variety of purposes. The credibility associated with these media is sometimes contested, and their acceptance into school practices has been debated. Focus group interviews with teachers and librarians in upper secondary schools in Sweden are used to investigate conceptions and experiences of activities involving the critical evaluation of participatory media, with a particular focus on Wikipedia. Three themes are addressed. The first concerns how the teaching of the critical evaluation of sources is organized and comanaged between teachers and librarians. The second describes educators' experiences of print versus digital media, and their worry because students have problems negotiating the information architecture of print media. The third theme deals with conceptions of the credibility of Wikipedia. Four conceptions of credibility are identified: credibility is associated with the control and stability of a source; it is considered to be strengthened when several sources support a claim; it is viewed as situational and partial, rather than absolute; and it is associated with a multiplicity of voices and democratic forms of production. These findings may be used to inform educational activities around credibility and authority in schools by raising self-awareness among educators of various ways to talk about the credibility of sources with both colleagues and students. 相似文献

A review of extant research evidence indicates that when source identification is delayed until after the message has been presented, the differential effectiveness of high‐ and low‐credibility communicators is reduced. In particular, those combinations of credibility level and advocated position that are ordinarily (i.e., with pre‐message identification) relatively advantageous (a low‐credibility source with a proattitudinal position, or a high‐credibility source with a non‐proattitudinal position) have persuasive effectiveness reduced by delayed identification, whereas those combinations that are ordinarily relatively disadvantageous (a high‐credibility source with a proattitudinal position, or a low‐credibility source with a non‐proattitudinal position) enjoy enhanced effectiveness with delayed identification. The magnitude of the effects associated with identification‐timing variations is quite large (mean absolute value of d = .753), at least by comparison to other factors for which quantitative estimates of persuasive effect are available. The observed effects place constraints on explanations of credibility's effects; in particular, credibility's effects cannot be explained through the mere association of a given communicator with a particular position. 相似文献

The extent to which information sources, that stand behind virtually all the news, are perceived by journalists as credible is a key determinant of the likelihood of their obtaining news access and public voice. The nature of source credibility judgment in journalism, however, is disputed between two major schools: while the “visceral” camp contends that it is highly subjective, intuitive and biased, the “discretional” camp perceives it as a far more reasonable and legitimate journalistic tool. The present study attempts to uncover evidence of both “visceral” and “discretional” judgment by studying the conceptual credibility (trustworthiness ratings) and practical credibility (practices indicating trust or skepticism, such as cross-checking and attribution) and the congruence between the two in a sample of 840 news items based on 1870 news sources. Findings were gleaned in face-to-face reconstruction interviews with reporters from nine leading Israeli news organizations, who reconstructed, source by source, the processes behind their items, shortly after their publication. Pro-discretional evidence shows that while journalists perceive their own experience as more credible than that of any other human agent, they do tend to stick with sources they perceive as more credible, the majority of which were relied on in the past, granting them more ready acceptance. Pro-visceral evidence, in turn, demonstrates that even the least credible sources receive substantial news space, some without any cross-checking. Furthermore, reporters ranked their sources' credibility even when they had no former record of trustworthiness. The paper suggests interpreting the composite of these findings as discretional logic with islands of visceral judgment. 相似文献

This study evaluates the role of spokespersons and message control in complex organizations facing ambiguous crises. Specifically, the Centers for Disease Control and Prevention's (CDC) response to the anthrax crisis in 2001 is offered as a case study. A textual analysis of CDC telebriefings and corresponding print media coverage of the anthrax crisis reveals the use of multiple spokespersons and poor message control resulted in a seemingly fragmented CDC message and apparent loss of CDC credibility. The study concludes that limiting the number of spokespersons and appropriate use of strategic ambiguity may afford organizations an opportunity to make sense of the situation, avoid confusing and contradictory messages and protect organizational credibility. Recommendations include (1) limiting the number of spokespersons, which allows for greater message control while reducing contradictory and inconsistent messages, (2) maintaining an organizational willingness to revise publicly stated positions as more accurate information becomes available, and (3) actively using strategic ambiguity as a mechanism to protect organizational credibility. 相似文献

National Public Radio (NPR) has built its reputation on in-depth analysis and unbiased reporting of information based on questions its reporters ask, the ways reporters tell their stories, and NPR's use of journalists as sources within their stories. This article focuses on understanding how these journalist-sources are used and how this practice contributes to the larger issues of source credibility facing media today. A content analysis of NPR's All Things Considered programming from 1999 to 2009 shows that NPR journalists are used as sources more often in stories about philosophical topics and significantly less often in stories that contain more hard data. 相似文献

This study investigated the factor structure of source credibility within the context of three situations in which communication typically occurs. The study tested the hypothesis that the situation in which the speaker communicates will influence the receiver's perception of the dimensions underlying the credibility of that speaker. The results indicated that the factor structure of source credibility across situations was variant. The scales used to measure the factors of trustworthiness and expertness may reflect more than one perceptual element for the receiver. The study indicated further that different types of communication in the same situation yield different source credibility factor structures. 相似文献

As a result of the controversy over the dimensionality of the ethos/source credibility construct and the associated plethora of empirical studies in the 1960s and 1970s, Aristotle's dimension of “goodwill” has been dismissed by many contemporary theorists and researchers. It is argued that this occurred as a result of errors made in the earlier empirical research and that “goodwill” can be measured, contrary to earlier claims, and should be restored to its former status in rhetorical communication theory. Empirical research is reported indicating the existence of the goodwill dimension as part of the structure of the ethos/source credibility construct and a measure of that dimension is provided with evidence for its reliability and validity. 相似文献

Established during the Sudeten crisis in September 1938, the BBC German Service played an important role in Chamberlain's appeasement policy and warfare towards Nazi Germany. Yet the BBC's employment for official propaganda, especially in peacetime, raised delicate issues of its independence from government control and of the objectivity and credibility of its broadcasts. This paper discusses, first, the origins of the BBC German Service and its role within Chamberlain's policy. Second, it analyses the relationship between the BBC and Whitehall. Third, it traces the evolution and development of the British propaganda strategy towards Germany and investigates how the concepts of ‘truthfulness’ and ‘objectivity’ were internally understood and employed by the BBC and Whitehall in their propaganda campaign. Finally, the paper argues that Chamberlain's propaganda strategy towards Germany collapsed during the Allied campaign in Norway in April 1940 precisely because it no longer conformed to its self-proclaimed principles of ‘truth’ and ‘objectivity’. As a result, the credibility of the BBC German Service suffered a significant, if ultimately temporary, setback. 相似文献

ABSTRACTMany news organizations have developed policies on the use of named and unnamed sources, including whether the latter can be directly quoted or paraphrased in news stories. In this experiment, we test how audience members respond to these policy dictates by measuring news credibility in a political story that manipulated whether the source was named, whether that source was directly quoted, and the source’s political connection to the story. We found that while each of these manipulations had little or no main effects, they combined to trigger a discernible change in credibility in the eyes of the audience. 相似文献

ABSTRACT Using Bloom's Taxonomy, this article provides a practical approach for enhancing critical thinking by business students. The article first describes Bloom's Taxonomy and how the model may be used as a framework for engaging business students in higher-order thought. It then explains how secondary research methods can be used to move business students to the higher planes of thought identified in Bloom's Taxonomy. Lastly, Herrick's criteria are used as a framework to analyze and evaluate the quality of secondary sources. 相似文献

This research explored the perceptions of university students about the credibility of information being shared on Facebook. The data were collected using an online questionnaire from university students who were Facebook users. A total of 325 usable responses were received which were analyzed using SPSS. The results revealed that these students perceive information shared on Facebook as credible and of good quality. The source credibility, medium credibility, and information quality had positive and significant relationships with each other. The age, social background, and educational level of students appeared to predict the credibility of information shared on Facebook. These results are useful for information professionals and social media managers in extent to understand and cater to the demands of information consumers. These findings would also be helpful for teachers, information providers, and researchers to understand the perspectives of developing countries' students on the credibility of social media information. Furthermore, this study is supposed to be a valuable addition in existing literature which could provide guidelines for novice researchers, interested in exploring the area, especially in the context of Facebook users in a developing country's context. 相似文献

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

This study investigated the variability of scales representing four factors of source credibility and the overall factor structure of subjects’ perceptions of and attributions to a message source. The results confirmed the hypotheses that (1) scales representing factors of source credibility will change over time, and (2) the factor structure (the number of significant factors and the amount of variance accounted for by the factors) would also change over time. The authors suggest that if the view is accepted that communication is an ongoing dynamic process, then an individual's experiences in the communication setting and the variables affecting perceptions of the process will be expected to change continually. 相似文献

ABSTRACT By administering an online experiment, this study examined how source and journalistic domains affect the perceived objectivity, message credibility, medium credibility, bias, and overall journalistic quality of news stories among an adult sample (N?=?370) recruited using Amazon’s Mechanical Turk (MTurk) service. Within the framework of the cognitive authority theory, the study found auto-written news stories were rated as more objective, credible (both message and medium credibility), and less biased. However, significant difference was found between a combined assessment condition (news stories with source and author information) and a message only assessment condition (news stories without source and author information) in the ratings of objectivity and credibility, but not bias. Moreover, significant differences were found in the objectivity and credibility ratings of auto-written and human-written news stories in the journalistic domains of politics, finance and sports news stories. In auto-written news stories, sports news stories were rated more objective and credible, while financial news stories were rated as more biased. In human-written stories, financial news stories were rated as more objective and credible. However, political news stories were rated as more biased among human-written news stories, and in cases where auto-written and human-written stories were combined. 相似文献

Considered by many to be the first war of the Information Age, the 2003 War in Iraq provided a unique opportunity for observing how the American mainstream press defined the Web's journalistic value and how it reacted to the competition from alternative online news sources. In an attempt to exert control over the Web as a journalistic space, the mainstream press used rhetorics of “professionalism” to discipline online news seekers into conforming to the definition of “news” favored by the mainstream press. This essay analyzes these tactics and their implications for the Web's journalistic potential, and concludes with a call for a more collaborative online journalism that maintains journalistic credibility while also incorporating a wider variety of perspectives. 相似文献

The current study investigates how social media affordances influence individuals’ source credibility perceptions in the presence of risk information, specifically examining how bandwagon heuristics interact with different identity heuristics at the individual level. The MAIN model and warranting theory serve as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. A posttest-only experiment with a self-report questionnaire was administered to participants. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness. Authority cues strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments. 相似文献
