In a useful article regarding testing for moderator variables in meta‐analysis, Hall and Rosenthal (1991) suggest, among other things, that when the sample of studies is large enough, it is acceptable to use ordinary inferential statistics such as the analysis of variance to test for moderator variables. However, because meta‐analytic data points (effect sizes) differ in important ways from those for which ordinary inferential statistics were designed, we recommend that analysts use conventional meta‐analytic statistics, which are at least potentially more informative about the literature in question. Hall and Rosenthal also suggest that tests of effect size variability should play a minimal role in meta‐analytic model tests. We concur that these tests of homogeneity cannot alone test for moderator variables and that at least tests between mean effect sizes should be performed. However, consistent with Hedges and Olkin's (1985) meta‐analytic framework, we show how homogeneity tests provide additional and valuable information regarding how completely a moderator (or set of moderators) explains the variation of effect sizes. Therefore, these goodness‐of‐fit statistics may prove quite valuable, especially in meta‐analyses of highly variable study outcomes. We further recommend that in meta‐analyses for which study outcomes are already consistent, analysts should continue to perform model tests if they have theoretical expectations about moderators. We discuss these and other meta‐analytic model testing concerns.  相似文献

ABSTRACT

High-choice media environments allow people to cocoon themselves with like-minded messages (confirmation bias), which could shape both individual attitudes and perceived prevalence of opinions. This study builds on motivated cognition and spiral of silence theory to disentangle how browsing political messages (both selective exposure as viewing full articles and incidental exposure as encountering leads only) shapes perceived public opinion and subsequently attitudes. Participants (N?=?115) browsed online articles on controversial topics; related attitudes and public opinion perceptions were captured before and after. Multi-level modeling demonstrated a confirmation bias. Both selective and incidental exposure affected attitudes per message stance, with stronger impacts for selective exposure. Opinion climate perceptions mediated selective exposure impacts on attitudes.  相似文献

This study assessed the extent to which six individual difference variables—sex, interpersonal construct differentiation, interpersonal construct abstractness, emotional empathy, and two aspects of communication apprehension—affect the perceptions of preformulated comforting strategies. Theoretical, methodological, and pedagogical implications of the findings are discussed.  相似文献

This study aims to understand the psychological mechanisms of the generation of viewers’ emotional reactions in successful media events and the role of social identity in the process. An online survey was conducted among Chinese viewers shortly after an important national ceremony was broadcast in China. A direct route between viewers’ media consumption and emotional arousal and a mediated route between them through cognition of the symbolism in the event were found. However, high-nationalist viewers were only aroused through symbolic cognition, while low-nationalist viewers gained emotions through both the direct and the indirect routes. The findings suggest two psychological mechanisms of ritual communications moderated by social identities and clarify the role of social identity in media ritual theories.  相似文献

ABSTRACT

Purpose: The present study aims to determine and compare the views of directors and users of public libraries on the use of social media for the marketing of library services.

Methodology: Data collection was done through two researcher-made questionnaires, one from the viewpoints of directors and one investigating the views of users. The questionnaires’ validity was done by four libraries and Information Science professionals, and the reliability was determined by the Cronbach’s alpha coefficient. The statistical population of this research is made up of all directors and users of 12 public libraries of the city of Isfahan, one of the largest cities in Iran.

Findings: In users’ viewpoints, the “interaction capability” is the most important feature that social media marketing can have in libraries. From the viewpoints of the directors, “creating a true picture of the role of the library” and “informing users about library services” are among the most important reasons for the marketing of libraries in the social media. From the perspective of both groups, the Telegram is the most appropriate medium for the marketing of library services.

Results: To maintain their customers and their market position, libraries need to use more exciting tools such as social media for marketing. Library directors of this study emphasized on this fact and 79.1% of users expressed interest in receiving library information through social media.

Value: The findings of this study would help the library directors to better decide on the marketing of their library services in social media.

A survey of 273 children in grades 3, 6, and 9, and their parents investigated parental mediation effects on a child's message interpretation process both from a child's and from a parent's perspective. The study found that children's reports of positive mediation (parental reinforcement of media messages) were significantly higher than parents' reports. Parents and children agreed more closely on reports of negative mediation (counter-reinforcement of media messages). Only the children's reports predicted variables influencing their decision-making for drinking alcohol. The results suggest that children's reports are probably more useful than parents' reports for predicting a child's cognition and behavior.  相似文献

ABSTRACT

This study investigated the use of Twitter in terms of personal and academic variables of students. These included gender, grade point average (GPA), and year level. Data were collected from undergraduate students at the College of Social Sciences at Kuwait University. A structured questionnaire was used as the data collection instrument. The findings show that the majority of respondents use social media, 42.8% use Twitter “sometimes,” and 44.4% use it “always.” There is no significant difference between males and females, except for social influence (SI). There is a statistically significant difference in the use of Twitter as an information source among students for different academic year levels, with the highest mean for senior students. However, no significant differences were found by students' GPA scores. Further investigation focusing on variables such as students' level of confidence and skills of using Twitter, such as the effect of course content, etc., would provide more insight into the use of social media platforms in higher education.  相似文献

The communicating of emotional support would seem to be an aspect of any successful relationship. Additionally, it would seem to reason that how one communicates emotional support would be an aspect of a relationship pertinent to communication research. Unfortunately, there is very little empirical evidence that illuminates how this is related to other relational outcomes such as trust. Weber and Patterson (1996) first developed a measure that taps into how much emotional support one receives from a specific other. In their initial scale development piece the authors validate the Communication Based Emotional Support Scale (CBESS) by finding positive correlations with both relationship solidarity and relationship satisfaction. This current study aimed to further validate the CBESS by exploring its relationship to trust, self‐disclosure, and feelings of being understood.  相似文献

Objectives: Often, there are media events (e.g., local and national elections, the Super Bowl) that match up with what we hope to accomplish in a particular class. The purpose of this semester-length project for students was threefold: (1) to read and comprehend literature related to communication studies, media, and political strategy; (2) to collect and analyze data; and (3) to participate in civic engagement by taking part in Presidential DebateWatch events, both as an audience member and through the use of Twitter.  相似文献

ABSTRACT

Scholars disagree on whether the media environment has become more concentrated, fragmented, polarized or overlapped. By pooling data from a total of 250 audience surveys conducted over 9 years, we investigated the evolution of a cross-platform audience network during a time of transition in the media environment. We found that both the fragmentation and duplication of the media system changed in a curvilinear manner. More importantly, this study showed that the center of the cross-platform network was transferred from offline to online. This study emphasizes the dynamic of media choice at various stages of media technology development.  相似文献

This study explicates the mechanism underlying the process through which news and entertainment media shape people's personal- and societal-level risk perceptions. It combines the psychometric paradigm with the impersonal- and differential-impact hypotheses, highlighting the roles that cognitive and emotional dimensions of risk characteristics play in risk perceptions. Analysis of an online survey among 384 adults from the general population of South Korea in the context of H1N1 flu yields three major findings: (1) exposure to news media is positively correlated with the cognitive dimension of risk characteristics, while exposure to entertainment media is positively correlated with both the cognitive and the emotional dimensions of risk characteristics; (2) the emotional but not the cognitive dimension of risk characteristics is positively related to both personal- and societal-level risk perceptions; and (3) exposure to entertainment media affects personal-level risk perceptions – not directly but indirectly through the emotional dimension of risk characteristics. Theoretically, this study expands the impersonal- and differential-impact hypotheses by explicating their underlying mechanisms and incorporating arguments from the psychometric paradigm. It also adds new knowledge to the psychometric paradigm by highlighting the differential roles of the cognitive and emotional dimensions of people's perceived risk characteristics in risk perceptions. For risk communicators, this study highlights the importance of using entertainment media for shaping risk perceptions and educating the public about risk issues.  相似文献

Abstract

Historical studies using computers and social science research methodologies share many interests, techniques, methods and approaches with modern information science. The major difference is a focus on retrospective rather than contemporary research topics and attendant differences in methods resulting from the nature of historical sources and the impact of time on interpretation. Whereas historical informatics evolved as a focus on computer science and history from quantification research, this field is still growing and absorbing in an interdisciplinary manner material, methods and approaches from other fields in accord with the syncretic nature of History. This enlarged arena may be called Historical Information Science, which is exemplified by the recent conferences and activities of the International Association of History and Computing (IACH).  相似文献

ABSTRACT

We applied the selection, optimization and compensation (SOC) model of successful aging to media use. Using a new self-report measure to assess selective and compensatory media use we illustrate the role of these media selection strategies in successful aging. In other words, we link compensatory and selective media use to different indicators of well-being among older nursing home residents and for a group of younger adults, which served as a comparison group. Selective media use was positively related to well-being for older, but not for younger adults, and compensatory media use was negatively related to well-being for both younger and older adults. In a second study, we replicated these findings with a sample of healthy older adults.  相似文献

ABSTRACT

Using expectancy violations theory, this study examined how the communication of unexpected feedback messages evoke emotional responses. A convenience sample (N = 309) reported instances of unexpected feedback within the last month. Results showed that receipt of the feedback message types were considered moderate-to-high violations. Violation expectedness and valence were negatively associated with the emotional responses, but violation importance was positively associated with the emotional responses. Finally, hurt and anger (but not surprise) were positively linked to perceptions of relational damage between the message sender and receiver. Taken together, our study demonstrates that expectancy violations are connected to emotions and relational outcomes.  相似文献

This study took the form of a pretest posttest nonequivalent natural quasi‐experiment. Despite the fact that previous researchers have indicated that media events are formative in the third‐person effect hypothesis, it was hypothesized that a major media event acting as a secondary stimulus would have no effect on the level of third‐person effect measured in regard to the primary stimulus despite the fact that both pertained to the same topic. This hypothesis was confirmed. This study indicates real world interactions of the third‐person effect hypothesis are complex, and the third‐person effect may operate less in the real world than previous experiments indicate.  相似文献

This essay compares legal and mainstream news discourses surrounding the Webb/Dotson rape recanting case, focusing on reasons why the two discourses derived opposing conclusions about Dotson's guilt. It argues that the tendency of mainstream news media to highlight emotional and personal elements helped construct a picture of Dotson as innocent and affable, while the tendency of legal discourse to emphasize mutually exclusive categories contributed strongly to a picture of Dotson as guilty regardless of Webb's recanted story.  相似文献

The intensity of the viewing experience people have while watching television was expected to enhance recall of commercials and also to render commercials less vulnerable to negative attitude change over multiple exposures. The effects of two variables, commercial induced emotion and product involvement, were tested in an experiment where people watched one hour of programming and embedded commercials on four consecutive days. Testing occurred after the fourth session; ads were repeated from two to 12 times during this time period. Broadly stated, findings indicate that emotional appeals and product involvement have favorable effects on brand name recall, attitudes, and purchase intention. Results are discussed with regard to their managerial and social implications.  相似文献

Abstract

This study examines convergence as both a concept and a process. It examines the current state of convergence, various definitions of convergence, convergence practices, and it identifies Seven Observations of Convergence to be used as a strategy for best practices for organizations to integrate new and old media. Everett Rogers (1995) diffusion of innovations and the five stages of the innovation process in organizations, coupled with innovation management research are theoretical foundations used to examine the infusion of technological changes into business practices in the media industry. The study is based on research conducted during the summer of 2002 that included in‐depth interviews, participation‐observation, and archival documents from three leading corporate media groups and convergence pioneers‐Tribune Company, Media‐General, and Belo Corp at their integrated business units in Chicago, Dallas, and Tampa, Florida. The three organizations were selected for field study because they are convergence pioneers that fell under the grandfather clause of the U.S. Federal Communications Commission 1975 cross‐ownership rule and were allowed to maintain ownership of their television broadcast and newspaper business units in the same market.  相似文献

ABSTRACT

Social media have become useful tools for audiovisual promotion, especially to reach niche audiences. Twitter promotional strategies have been widely studied, yet other growing platforms such as Instagram have been less analyzed. This paper examines the Instagram promotional strategies of two pay-per-view platforms (HBO and Netflix) in two markets (the USA and Spain). A total of 731 messages, posted between May and November 2017, were analyzed to identify their formal features, objectives, and their content’s emotional and cognitive elements posted on HBO and Netflix’s Spanish and US accounts. The results showed acute differences between how HBO and Netflix use their Instagram accounts in the two markets (Spain and the USA). The Spanish accounts mostly provided information, while the US accounts both provided information and promoted program content. Posts from US accounts more frequently included links to social media, particularly to celebrity accounts. Spanish accounts relied more on diegetic images, whereas US accounts emphasized non-diegetic and off-set images. Netflix used humor more than HBO did, and a stronger focus on celebrities. Humor and positive tone were found to be linked to higher engagement.  相似文献
