Concepts from Heider's “Attribution of Responsibility” theory were used to investigate the process of message source evaluation. The results of a role‐playing experiment indicate that: (1) When a message source's previous behavior has had favorable consequences for a receiver, the source will be rated more “safe,” “qualified,” and “dynamic” to the extent that responsibility for those consequences are attributed to the source; and (2) when the source's previous behavior has had unfavorable consequences for the receiver, the source will be judged less “safe” but more “qualified” and “dynamic” to the extent that responsibility for those consequences are attributed to the source. 相似文献

Eighty English‐Canadian subjects listened to a taped persuasive communication attributed to either an English‐Canadian or a French‐Canadian source and read with either an English‐Canadian or a French‐Canadian dialect. Both the speaker's dialect and the source's ethnicity affected the audience's reaction to the message. French‐Canadian subjects responded more favourably to a communication read with an English‐Canadian dialect than one read with a French‐Canadian dialect and responded more favourably to a communication attributed to an English‐Canadian source than one attributed to a French‐Canadian source. Furthermore, French‐Canadian sources were evaluated less stereotypically when communications attributed to them were read with an English‐Canadian dialect than when read with a French‐Canadian dialect. Methodological and theoretical implications of these results are discussed. 相似文献

Based on the hostile media effect (HME), this 2 (partisan opinion) × 2 (news source) × 2 (content valence) factorial experiment investigated how partisans (N = 132), in terms of perceived bias and credibility, assess same-sex marriage coverage by either an online mainstream news source or a citizen blog. Partisans who disagreed with the content's valence evaluated both mainstream online news and the blog posting as more biased and less credible than did partisans who agreed with the content's valence. The perceived reach of blog postings appears to generate a relative HME similar to that triggered by mainstream news. In particular, this study suggests that user-generated content—specifically blog postings—might generate a stronger relative HME than that observed with mainstream news. 相似文献

A basic understanding of the Internet's physical and operational structure is one element of information literacy. In this article, “traceroute” and “whois” commands are demonstrated as tools that librarians can use to illustrate how the Internet is geographically distributed, how businesses enable and control information sharing, and how to check a source's credibility by determining website ownership. With these tools, students can gain a better understanding of how online information is created, accessed, and affected in ways that may be otherwise invisible. 相似文献

ABSTRACT Trustworthiness is key in journalism, yet some journalists intentionally deceive their audiences by fabricating sources or inventing news stories altogether. Earlier research suggests that deceitful news articles have characteristics that are different from trustworthy news articles. We aimed to confirm and expand on the existing literature by examining the case of Perdiep Ramesar, an esteemed Dutch journalist until it was discovered in 2014 that sources were non-existing in 126 of his articles for national newspaper Trouw (“Fidelity”). Using content analysis, we searched for systematic differences in source use and presentation comparing Ramesar’s deceptive news articles with two same-sized sets of reliable articles, (1) articles on similar topics from other journalists and (2) articles with verifiable sources from Ramesar himself. Results indicate that compared to real news sources, fictitious sources are more often secondary definers, who are presented in more stereotypical ways and through more and longer direct quotations. Furthermore, negations and self-references occur more often in deceptive news articles. 相似文献

The Florida Legislature created the Joint Committee on Information Technology Resources for the purpose of, in part, analyzing the impact of advances in information technology on the Florida Public Records Law. In responding to the U.S. Information Industry Association's recently promulgated access principles for state and local government, the author found that although Florida does not actively encourage a diversity of information sources, such diversity is an indirect result of the state's long tradition of open access. The public's right of access is now guaranteed in Florida by a new constitutional amendment that guarantees every person the right to inspect or copy the public records of all three branches of Florida government.Florida's law is silent about an agency's obligation to provide a public record in a particular medium. However, the Joint Committee has proposed legislation that would require an agency to provide a copy of a public record in the medium requested. Additionally, the proposed legislation would allow a reasonable fee for costs for the labor and overhead associated with duplicating or copying a computer database; current law allows only the actual cost of duplication. In an effort to insure equal and timely access, this legislation also contains a provision that requires agencies to consider public access and redaction of exempt information in the design and development of all electronic recordkeeping systems.In an attempt to avoid monopoly control over public information, the author sponsored legislation last year that would have repealed Florida's law allowing the copyright of agency-created software. The Joint Committee's proposed legislation has a provision that would assure meaningful access to data controlled by proprietary software and would also preclude an agency from entering into any contract that would impair the right of the public to inspect and copy public records. 相似文献

The gap between the approval of RTI laws and their implementation leaves room for discretionary bias and discrimination from government officials. This paper explores possible discretionary bias and ultimately discriminatory behavior exhibited by Uruguayan government agencies while answering RTI requests. We explore whether public officials are more likely to respond to requests from citizens that are informed about their right under the RTI law vs regular citizens, as well as from influential citizens (journalists and firm owners). We also assess whether public servants' responses to RTI requests are gender-biased. We conducted a randomized field experiment to test for unequal treatment given to citizens' requests by Uruguayan government officials, considering different citizen categories. We find that only those citizens who know the RTI law and invoke its existence have a greater likelihood of obtaining an answer from bureaucrats. This result is driven mostly by men's requests declaring they know the law when making their request, while invoking the law doesn't make a difference in responses to women. These findings show that public campaigns to promote citizens' awareness of RTI laws and their use, not only would increase requests, but also governments' responsiveness regarding RTI requests. 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

The people we see in news media can affect our perceptions of public opinion through exemplification. Although research shows that individuals interviewed in a news story can influence perceptions of public opinion, little attention has been paid to the role that source type and audience attitudes play in the exemplification process. This study tests how the exemplification process is influenced by different types of news sources featured in an article (e.g., vox pop, protester, and interest group interviews) and the audience's own political ideology. The study finds that the perceived typicality of sources is affected by both source type and how much an audience member agrees with the source. Source type is also found to directly affect perceptions of public opinion. 相似文献

Anthropologists at seven universities were surveyed in order to discover: the ways in which they go about locating information of value to them; the information sources that they use and that are of the greatest significance to them; the adequacy of the library service being currently provided to anthropologists; and any opinions they have on the subject of their information needs. Results show that anthropologists; information requirements differ somewhat from those of other social scientists. Reference lists in journals and books are often used to locate information sources; journals are the most important information source. However, cultural anthropologists report that their own field data is their most significant source. Anthropologists use pictorial sources and maps more frequently than social scientists in general do; they also make great use of interlibrary loan. Most of the information needs of the majority of respondents are met by their university's library. Older scholars tend to use databases less than younger ones do; online abstracts and indexes are most important to anthropologists than their print versions are. Some respondents express a great desire for a database which would include current references, abstracts, and articles in anthropology. 相似文献

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

Although not commonly acknowledge, Information & Referral (I & R) services are now an integral feature of many public academic libraries. Two such special services offered in Hclm-Cravens Library, Western Kentucky University, illustrate this development. The Grants Information Center, which evolved from a Foundation Center Cooperative Collection, identifies funding sources for a wide variety of research and developmental projects for acadcrnic and public pakons. The Library's map collection performs a similar function with respect to nonlibrary sources of caitographic information and map products. Both services enhance the library's contribution to the university and to its larger community. 相似文献

The present work examines the role of source vs. content cues for the confirmation bias, in which recipients spend more time with content aligning with preexisting attitudes. In addition to testing how both source and content cues facilitate this biased pattern of selective exposure, the study measures subsequent attitude polarization. An experiment (N?=?120) presented messages with opposing political stances, associated with unbiased or slanted sources. Software tracked selective exposure in seconds, and attitudes were measured before, immediately after, and two days after message exposure. Further, information processing styles were assessed. The confirmation bias emerged regardless of source quality. Information processing styles moderated the confirmation bias as well as selective exposure to messages from unbiased vs. slanted sources. Selective exposure reinforced attitudes days later. 相似文献

A survey (n = 953) and 8 interviews reveal journalists reject the notion that the sources of seminal story ideas should be attributed. Broadcasters and those in competitive markets were less likely than other journalists to see idea attribution as important, yet rejection of idea plagiarism was so widespread (74.1%) that no correlations surfaced with job type, career longevity, or ethical decision-making barometers. Although omitting the source of ideas may be widely accepted, it is not benign. Depriving readers of the origin of news limits their ability to critique a story's validity and in some cases precludes them from getting the story at all, as some journalists, especially broadcasters, would rather ignore a story than tacitly acknowledge a competitor. 相似文献

Objectives:
The research determined (1) the information sources that family physicians (FPs) most commonly use to update their general medical knowledge and to make specific clinical decisions, and (2) the information sources FPs found to be most physically accessible, intellectually accessible (easy to understand), reliable (trustworthy), and relevant to their needs.Methods:
A cross-sectional postal survey of 792 FPs and locum tenens, in full-time or part-time medical practice, currently practicing or on leave of absence in the Canadian province of Saskatchewan was conducted during the period of January to April 2008.Results:
Of 666 eligible physicians, 331 completed and returned surveys, resulting in a response rate of 49.7% (331/666). Medical textbooks and colleagues in the main patient care setting were the top 2 sources for the purpose of making specific clinical decisions. Medical textbooks were most frequently considered by FPs to be reliable (trustworthy), and colleagues in the main patient care setting were most physically accessible (easy to access).Conclusions:
When making specific clinical decisions, FPs were most likely to use information from sources that they considered to be reliable and generally physically accessible, suggesting that FPs can best be supported by facilitating easy and convenient access to high-quality information.Highlights
- Medical textbooks were the most popular information source for family physicians'' (FPs'') clinical decision-making purposes, and medical journals were the most popular information source for the purpose of updating FPs'' general medical knowledge.
- FPs considered medical textbooks to be the most reliable (trustworthy) source, colleagues the most physically accessible, and continuing medical education the most relevant and intellectually accessible.
- The lowest ranked information sources across all four attributes were personal digital assistants, mental health professionals, pharmaceutical sales representatives, and other decision aids.
Implications
- The most popular information sources for clinical decision-making purposes among FPs were sources characterized as reliable and generally physically accessible.
- This study suggests the need for further research into interventions that target information access barriers in FPs'' practice settings and the promotion of reliable evidence for FPs'' clinical decision-making purposes.

In Fall 2006, a faculty member in George Washington University's University Writing 20 (UW20) program began incorporating service learning into her theme-based first-year writing course. Along with her librarian partner, they linked two research assignments to the service work of the students. An end-of-semester survey was administrated over three semesters with one question asking if the student's research process was affected by their service experience. In reviewing and analyzing student comments, four themes emerged: increased motivation, use of numerical data and primary sources, increased knowledge in approaching and limiting topics, and the potential for bias. 相似文献

This paper addresses the problem of estimating the size of a deep web data source that is accessible by queries only. Since
most deep web data sources are non-cooperative, a data source size can only be estimated by sending queries and analyzing
the returning results. We propose an efficient estimator based on the capture–recapture method. First we derive an equation
between the overlapping rate and the percentage of the data examined when random samples are retrieved from a uniform distribution.
This equation is conceptually simple and leads to the derivation of an estimator for samples obtained by random queries. Since
random queries do not produce random documents, it is well known that the traditional methods by random queries underestimate
the size, i.e., those estimators have negative bias. Based on the simple estimator for random samples, we adjust the equation
so that it can handle the samples returned by random queries. We conduct both simulation studies and experiments on corpora
including Gov2, Reuters, Newsgroups, and Wikipedia. The results show that our method has small bias and standard deviation. 相似文献
