Although a growing number of studies are examining the relationship between Internet use and political participation, varying study characteristics make the overall effect size difficult to estimate. Using a meta-analysis, we estimated the mean effect size and tested whether the effect size was influenced by study characteristics. Data for this meta-analysis were derived from 56 papers reporting 63 independent studies. Results revealed that Internet use had a weak relationship with political participation (rc?=?.22). Moderator analyses demonstrated that type of Internet use, Internet use measure, Internet use for news, type of political participation, sample origin, and survey year significantly moderated the relationship between Internet use and political participation. For instance, Internet use including news (rc?=?.27) had a significantly stronger relationship with political participation than did Internet use excluding news (rc?=?.19). European samples (rc?=?.27) had the largest mean correlation followed by North American samples (rc?=?.23) and Asian samples (rc?=?.18) in decreasing order of strength of relationship. The theoretical and methodological implications of the findings are discussed.  相似文献

Although narratives are often credited with the capacity to change opinions, empirical tests of this prediction have produced mixed results. To provide a more precise test of narrative's effect on beliefs, attitudes, intentions, and behaviors, we performed meta-analyses on studies that evaluated narrative's persuasive influence on these outcomes. Results suggested positive relationships between exposure to a narrative and narrative-consistent beliefs (k?=?37; N?=?7,376; r?=?.17), attitudes (k?=?40; N?=?7,132; r?=?.19), intentions (k?=?28; N?=?5,211; r?=?.17), and behaviors (k?=?5; N?=?978; r?=?.23). Moderator analyses on the effect of fictionality yielded mixed results. Neither medium of presentation nor research design influenced the magnitude of the narrative-persuasion relationship. However, results suggested the presence of unidentified moderators.  相似文献

The results of the investigations providing data on the connection between measures of sexual arousal and positive psychological affect indicate a positive relationship whether measured directly (r=.212) or by a comparison of manipulation check data (r=.223). Female research participants demonstrate more negative emotional responses than men exposed to the same content (r=?.248), but the level of physiological arousal favors men by a much smaller magnitude (r=.134). The response to pornography on the basis of gender reflects not only a physiological difference in reaction but a psychological interpretation of that reaction as well.  相似文献

A random-effects meta-analysis was undertaken to examine the effectiveness of the Door-in-the-Face (DITF) persuasive message strategy on compliance. Results indicate an overall significant effect of the DITF strategy on verbal compliance (k=78, r=.126), but an insignificant effect for behavioral compliance (k=39, r=.052). In terms of verbal compliance, the DITF strategy works significantly better than controls for different samples, across varied communication media, and for prosocial causes. Additionally, the DITF technique is more successful than controls for volunteering/research than other target behaviors (e.g., monetary donation). For both verbal and behavioral compliance outcomes, the toughness (measured as amount of baseline compliance) of the donation context negatively predicted the magnitude of the DITF effect. It is argued social responsibility theory best accounts for observed moderator factors.  相似文献

In response to rising consumption effects on the environment, green advertisers have employed different tactics to advertise their unique products. Limited research has explored the impact of culturally congruent appeals in green advertising. A total of 118 (N) adults participated online to assess the influence of these appeals in a cross-cultural context. Findings indicate that collectivistic appeals worked best among Indian consumers while individualistic appeals were more effective for Americans. Ad novelty and environmental concern were important covariates. Implications for advertisers are discussed.  相似文献

One reason librarians are confident they have a role to play in fighting misinformation is the level of trust in libraries as institutions. Exactly how they might leverage that trust remains unclear and untested. Building on recent work in correcting health misperceptions on social media, this study tests whether libraries can leverage trust to combat misinformation online. Using a misperception about the influenza vaccine as a test case, an experiment (n?=?625) was conducted in fall 2018 using Amazon's Mechanical Turk. Results suggest that the misperception can be reduced, but not by library institutions. An unsuccessful follow-up (n?=?600) suggests that the effectiveness of the correction is season dependent and opens the possibility that libraries may yet play a role, but not necessarily because they are trusted. Future library proposals for combating misinformation need to be developed and tested within a broader contemporary misinformation research program.  相似文献

The present study expands on prior work on the use of narratives in persuasive communication by examining students’ (N = 201) reactions to six organ donation public service announcements (PSAs). Reactions to the type of appeal, donor-focused or recipient-focused, were also explored. Results indicated that being immersed in the PSA was positively associated with message reactions and negatively associated with threats to overall freedom of choice when deciding whether or not to become an organ donor. Those perceived threats partially mediated the relationship between immersion into the story of the PSA and message reactions, such that increased threats were associated with reduced message reactions. Individuals exposed to the recipient-focused appeals were more interested in the narrative of the PSAs than those exposed to donor-focused appeals. Results are discussed in the context of future message and campaign development.  相似文献

The current study situated loss/gain-framing research in the extended parallel process model and tested whether two message features (dose, efficacy appeals) and four individual difference variables (walking self-efficacy, grit, consideration of future consequences, health information overload (HIO)) moderated the impact of message framing on intentions to engage in physical activity. Adults (N?=?341, Mage?=?38.09, SD?=?10.94) were randomly assigned to one of eight message conditions advocating exercise behavior. All four individual difference variables significantly moderated framing effects such that gain-framed messages were more effective for individuals with lower walking self-efficacy, grit, and consideration of future consequences and loss-framed messages were significantly more effective for individuals with higher walking self-efficacy, grit, consideration of future consequences, and for those with lower HIO.  相似文献

Scholars have assessed the degree to which heterosexual men and women make differential judgments of flirtatiousness, seductiveness, and promiscuousness during cross-sex interactions. Findings from extant research suggest that men decode verbal and nonverbal communication cues differently than do women, and this difference results in men's tendency to rate individuals more highly in levels of these social–sexual constructs than do women. This paper reports the results of three meta-analyses that provided estimates of the magnitude of the sex differences in perceptions of flirtatiousness, seductiveness, and promiscuousness and argues that these results are consistent with error management theory. Sex of target and mode of observation interacted to impact observed sex differences. Sex differences were strongest for female targets when research participants were observers of face-to-face interactions (average r=.32), whereas sex differences in evaluations of flirtatiousness, seductiveness, and promiscuousness were strongest for participants who were rating male targets in face-to-face interactions (average r=.36). The implications of these results are discussed.  相似文献

Abstract

The dissemination of misinformation in health care and the sciences has become a growing concern over the last five years. Whether the false information is spread with malice or merely ignorance, researchers, providers, librarians, regulatory bodies, and internet platform providers have all begun taking steps to identify false information and halt its proliferation online. Some companies have begun looking at ways to apply artificial intelligence and machine learning to timely and widespread identification efforts. This column will investigate what technologies are currently being considered for addressing the misinformation crisis, discuss concerns over the application of such technologies, and consider methods for libraries to become more involved with the technological side of the issue.  相似文献

In this two-part study, a content analysis of advertisements published in Cambodian and Vietnamese magazines was first conducted to determine the kinds of advertising appeals (functional, individualistic, and collectivistic) that were most frequently employed. The findings indicated that across product types, the Cambodian ads contained more individualistic appeals. The Vietnamese ads, on the other hand, depicted more collectivistic and functional appeals. Next, an experiment was conducted to determine audience response to the use of three appeals in ads that promote four product types (informative, affective, habit-forming, and self-satisfaction). Vietnamese participants responded more positively to functional appeals across product types. They also preferred collectivistic rather than individualistic appeals for ads that promote habit-forming and self-satisfaction products. Cambodian consumers, on the other hand, registered more positive attitudes toward ads with individualistic and functional appeals.  相似文献

Over the past decade a remarkable number of revolutions worldwide imitated the touchstone youth movement Otpor, which played an influential role in ousting Serbian President Slobodan Milo?evi? in 2000. Given the continual presence of Western organizations and resources in Otpor's uprising, I argue that the movement demonstrates a type of communication termed glocal recursion—a rhetorical strategy that invites social change by imitating global methods of resistance, with slight variations, in local contexts. In addition to its time-based connotations (in which activists ground new messages in old texts), glocal recursion advances a space-based understanding of recursive appeals (with activists creating local messages from global structures). This essay analyzes four aspects of Otpor's glocal recursions, including its technological conditions, structured spontaneity, indigenous adaptations, and dialectical reappropriations. Various implications are drawn for communication research.  相似文献

Sex differences in people and things orientation have been reported in a range of psychobehavioural domains. Females, on average, score higher than males on people orientation, while males, on average, score higher than females on things orientation. In this article, I reanalyse recent data on sex differences in academic publishing using Scopus journal articles from 2017 (n = 27,710 articles in India; n = 285,619 articles in the US). The results show that in both India (rs = –.71) and the United States (rs = –.69), women were more prevalent as the first authors of articles in more people-oriented fields than in fields that were more things-oriented, which had a high proportion of male first authors. The findings indicate that there are similar cross-national patterns between US and India in field-specific female-to-male author ratios when factoring in the people and things orientation of those fields. Where the people and things dimension fails to explain sex differences in academic publishing, sex differences in the empathising–systemising quotients may explain residual variation in sex differences in research subject choices. The findings reported here extend existing psychobehavioural, developmental, and evolutionary research on sex differences in interests and cognitive styles.  相似文献

Abstract

Three paintings from a group of thirty-two attributed to Jackson Pollock (1912–1956) were examined at the Harvard Art Museums. Paint samples were examined using Raman spectroscopy, scanning electron microscopy–energy dispersive X-ray spectrometry (SEM-EDX), laser desorption ionization time-of-flight mass spectroscopy (LDI-MS), Fourier transform infrared spectroscopy (FTIR), pyrolysis–gas chromatography–mass spectrometry (py-GCMS) and carbon-14 (C-14) dating. Carbon-14 dating detected no 'bomb' carbon from atmospheric atomic testing. All three paintings contained pigments and media available only after Pollock's death, including PR 254, PY151, and an emulsion copolymer of n-butyl methacrylate and iso-butyl methacrylate.  相似文献

Much research on public communication campaigns has shown that the negative appeals (e.g. fear, guilt appeals) commonly used may not be effective for encouraging prosocial behaviors, as they can facilitate defensive processing. Self-affirmation theory suggests that self-affirmation may be a useful strategy for mitigating defensive responses to potentially self-threatening messages. This cross-national study explored the effect of self-affirmation on the persuasiveness of a threat appeal message in the context of climate change. An experiment with a 3 (no affirmation versus message-integrated affirmation versus message-separate affirmation)?×?2 (high self-threatening versus low self-threatening message)?×?2 (U.S. versus Korea) factorial design (N?=?225, U.S.; N?=?255, Korea) was employed to test this postulation. The results suggested that self-affirmation has a positive effect on perceived risk, attitude toward message, and intention to engage in environmentally-friendly behaviors, although this effect is limited to high self-threat conditions. Additionally, a statistically significant interaction between self-affirmation and culture was found for the effect on behavioral intention. Finally, message-integrated affirmation manipulation was found to be as effective as message-separate affirmation manipulation. The implications of these findings for public communication campaigns in terms of promoting prosocial behaviors are discussed.  相似文献

Greater fear arousal is associated with greater engagement with persuasive messages, and negative information and events are more potent than their positive counterparts. Hence loss-framed persuasive appeals, which emphasize the undesirable outcomes of noncompliance with the communicator's recommendations, should elicit greater message processing than do gain-framed appeals, which emphasize the desirable outcomes of compliance. But a meta-analytic review (based on 42 effect sizes, N = 6,378) finds that gain-framed messages engender slightly but significantly greater message engagement than do loss-framed messages. This effect is apparently not a result of whether the appeals refer to obtaining or averting negative (e.g., “skin cancer”) rather than positive (e.g., “attractive skin”) outcomes.  相似文献

The researchers examined student perceptions of campus and community newspaper credibility at the University of Florida using a Web survey (n = 1,906) of those enrolled in a general education class. A moderate correlation (r = .28) existed between college newspaper credibility and community newspaper credibility. Using hierarchical linear regression, the researchers found interest in news content to be a statistically significant predictor of credibility for both local newspapers and college newspapers. In addition, students whose parents encouraged them to read a newspaper found both newspapers more credible than did their peers, and exposure to a newspaper was found to be a strong predictor of credibility for that newspaper. Finally, the results of this case study also suggest White respondents find local newspapers more credible than other races. Implications for researchers and practitioners were discussed.  相似文献

Little is known in the United States of the various regional broadcasting associations. Even such basic volumes as Emery's National and International Systems of Broadcasting cover the major organizations—European Broadcasting Union, International Radio and Television Organization (OIRT), URTNA (Africa), Inter‐American Broadcast Association, and Asian Broadcasting Union (ABU)—in fewer than a dozen pages. The Journal of Broadcasting only has published materials on the first two of these. As global broadcasting over domestic channels becomes a satellite‐borne reality, this lack of information is bound to become more and more embarrassing.  相似文献

Objective:The purpose of this study was to compare pharmacy students’ ability to correctly answer drug information questions using Micromedex with Watson, Micromedex without Watson, or Google.Methods:This multicenter randomized trial compared pharmacy student responses to drug information questions using Micromedex with Watson, Micromedex without Watson, or Google from January to March of 2020. First- to fourth-year pharmacy students at two institutions were included. The primary outcome was the number of correct answers. Secondary outcomes were the time taken to answer the questions and differences in number of correct answers by pharmacy student year and institution.Results:The analysis included 162 participants: 52 students in the Micromedex group, 51 students in the Watson group, and 59 students in the Google group. There was a significant difference among groups in the total number of questions answered correctly (p=0.02). Post-hoc analysis revealed that participants in the Micromedex group answered more questions correctly than those in the Google group (p=0.015). There were no significant differences between Micromedex and Watson groups (p=0.52) or between Watson and Google groups (p=0.22). There was also no difference in time to complete the questions among groups (p=0.72).Conclusion:Utilizing Google did not save students time and led to more incorrect answers. These findings suggest that health care educators and health sciences librarians should further reinforce training on the appropriate use of drug information resources.  相似文献

Abstract

There are a number of important documents that provide guidance in the consideration of library services supporting nursing programs and students at a distance. Standards are available from the National League for Nursing Accrediting Commission (NLNAC), the American Association of Colleges of Nursing (AACN), and the Commission on Collegiate Nursing Education (CCNE). In addition, the Association of College and Research Libraries' (ACRL) Guidelines for Distance Learning Library Services offers interested parties another option, as do the more recently published Information Literacy Competency Standards for Higher Education. This paper reports on a survey concerning these documents and their usefulness to those planning or enhancing library services in support of distance nursing programs and students.  相似文献
