TL;DR: The results suggest that social media use generally has a positive relationship with engagement and its three sub-categories, that is, social capital, civic engagement, and political participation.
Abstract: This meta-analytic study reviews empirical research published from 2007 to 2013 with an aim of providing robust conclusions about the relationship between social media use and citizen engagement. It includes 22 studies that used self-reported measures of social media use and participation, with a total of 116 relationships/effects. The results suggest that social media use generally has a positive relationship with engagement and its three sub-categories, that is, social capital, civic engagement, and political participation. More specifically, we find small-to-medium size positive relationships between expressive, informational, and relational uses of social media and the above indicators of citizen engagement. For identity- and entertainment-oriented uses of social media, our analyses find little evidence supporting their relationship with citizen engagement.
TL;DR: In this article, a meta-analysing 34 empirical studies, representing a total sample of 32,938 participants and 129 independent correlations, it was found that trust substantially affected public perception of benefits regarding nuclear energy.
Abstract: Nuclear energy is widely regarded as a controversial technology that polarizes public opinion. Guided by the scientific literacy and cognitive miser models, this study systematically identified and examined the magnitude of the effects of 19 predictors on public perceptions of benefits, risks, and acceptance of nuclear energy. We meta-analysed 34 empirical studies, representing a total sample of 32,938 participants and 129 independent correlations. The findings demonstrated that trust substantially affected public perception of benefits regarding nuclear energy. Sex, education, public perception of benefits regarding nuclear energy, trust, and public deliberation substantially influenced public perception of risks regarding nuclear energy. Moreover, sex, education, public perceptions of benefits, risks and costs regarding nuclear energy, knowledge, and trust substantially affected public acceptance of nuclear energy. Country of sample and time period of data collection moderated public perceptions...
TL;DR: Examination of the spiral of silence on participants' likelihood to interact with social media suggests that “click-speech” could be considered a form of opinion expression, and suggests that the fear of isolation and a civil climate increased the likelihood of liking comments on Facebook posts.
Abstract: Opinion expressions on Facebook are characterized by “click speech” in which people express their opinions and support (or disagreement) of posts through the “like,” “comment,” and “share” buttons. This study uses a 2 (low vs. high opinion congruency) x 2 (message civility vs. incivility) between-subject factorial experiment to examine the spiral of silence on participants' likelihood to interact with social media. We randomly assigned 502 participants to one of four experimental conditions. Results indicate that the fear of isolation increased the likelihood of commenting on Facebook posts and a civil climate increased the likelihood of liking comments on Facebook posts. Findings suggest that “click-speech” could be considered a form of opinion expression.
TL;DR: The Hyperlink-Induced Topic Search (HITS) enhanced variant of the AKR technique performs better than other techniques, satisfying most requirements for a reading list and provides scope for extension in future information retrieval (IR) and content-based recommender systems (RS) studies.
Abstract: The requirements for the task of building an initial reading list in literature review are re-conceptualized and a novel retrieval technique centered on author-specified keywords of papers is proposed for this task.The HITS variant of the proposed technique best satisfies the requirements of the task in an offline evaluation experiment.The proposed technique is evaluated by 132 researchers using 14 evaluation measures in a user evaluation study.Relevance, Recency and Usefulness were identified as the measures with high agreement percentages from participants.Students group were more satisfied with the results than staff group.Three predictors for user satisfaction were identified through the evaluation study. An initial reading list is prepared by researchers at the start of literature review for getting an overview of the research performed in a particular area. Prior studies have taken the approach of merely recommending seminal or popular papers to aid researchers in such a task. In this paper, we present an alternative technique called the AKR (Author-specified Keywords based Retrieval) technique for providing popular, recent, survey and a diverse set of papers as a part of the initial reading list. The AKR technique is based on a novel coverage value that has its calculation centered on author-specified keywords. We performed an offline evaluation experiment with four variants of the AKR technique along with three state-of-the-art approaches involving collaborative filtering and graph ranking algorithms. Findings show that the Hyperlink-Induced Topic Search (HITS) enhanced variant of the AKR technique performs better than other techniques, satisfying most requirements for a reading list. A user evaluation study was conducted with 132 researchers to gauge user interest on the proposed technique using 14 evaluation measures. Results show that (i) students group are more satisfied with the recommended papers than staff group, (ii) popularity measure is strongly correlated with the output quality measures and (iii) the measures familiarity, usefulness and agreeability on a good list were found to be strong predictors for user satisfaction. The AKR technique provides scope for extension in future information retrieval (IR) and content-based recommender systems (RS) studies.
TL;DR: This paper reviewed and analyzed the role of social media in promoting political expression and participation in Confucian Asia, including China, Hong Kong, Singapore, South Korea, and Taiwan, and concluded that the strongest relationships are in democratic states, followed by hybrid and authoritarian systems.
Abstract: This study reviews and analyzes the published empirical research on the role of social media in promoting political expression and participation in Confucian Asia, including China, Hong Kong, Singapore, South Korea, and Taiwan. In addition to providing a narrative review of the literature, our analyses show clear numerical estimates of the relationships among different types of social media use (i.e., informational, expressive, relational, and recreational), political expression, and participation in Confucian states. The findings reiterate the importance of the expressive use of social media, showing its moderately strong relationship with participation. The findings also show weak positive relationships with informational and relational uses. We also examine the role of political systems in these relationships and conclude that the strongest relationships are in democratic states, followed by hybrid and authoritarian systems.
TL;DR: The Net Delusion: The Dark Side of Internet Freedom by Evgeny Morozov New York: Public Affairs, 2011 409 pages $16.99 [ILLUSTRATION OMITTED] as discussed by the authors.
Abstract: The Net Delusion: The Dark Side of Internet Freedom by Evgeny Morozov New York: Public Affairs, 2011 409 pages $16.99 [ILLUSTRATION OMITTED] In January 2010, Secretary of State Hillary Clinton gave a highly touted speech on Internet freedom in which she stated, "The freedom to connect is like the freedom of assembly, only in cyberspace. It allows individuals to get online, come together, and hopefully cooperate. Once you're on the Internet, you don't need to be a tycoon or a rock star to have a huge impact on society." Evgeny Morozov, in his book The Net Delusion, takes great issue with the implication, however, that the so-called "Arab Spring" and "Twitter Revolution" were caused by unfettered access to the Internet. Instead, Morozov, a research academic, provides a cautionary tale about what he argues is any attempt to establish a monocausal relationship to meaningful political change (especially when that single focus is information technology). The book opens with a discussion of cyber-utopianism and Internet-centrism--mind-sets that focus on the positive "emancipatory" aspects of Internet communication while ignoring the downsides. The argument throughout centers on nation-state policy, or lack thereof, that attacks the "wicked" problem of authoritarianism by, as a colleague of mine has dubbed it, "wiring the world." Morozov, expectantly, but importantly, cites the hedonistic world portrayed by Huxley and the "Big Brother" world of Orwell to consider both the proactive and reactive approaches to Internet freedom by authoritarian regimes. Interestingly, he notes that there is often a mix of both. Such regimes certainly use the anonymity and openness of the Internet to spy on their people and shutdown undesirable sites. But there is also a subtle approach that belies the jackboot on the keyboard methodology. While China may be known more for suppressing the Internet and for employing the masses to counter antiregime rhetoric, Russia imposes no formal Internet censorship. It relies on entertainment (porn is specifically cited) to soothe the masses, assuming that given options for political discourse and anything else, most opt for "anything else." Hitler would understand. And in nations where freedom is not widely understood from a western perspective, any bit of additional mindless diversion may be viewed as liberty by the populace. Perhaps most importantly, Morozov rails against social media determinism as driving the end of authoritarianism, labeling it "an intellectually impoverished, lazy way to study the past, understand the present, and predict the future." He does not dismiss the value of Facebook and Twitter to quickly mobilize like-minded individuals. He notes as well that the development of that very like-mindedness is complex and potentially can be manipulated by authoritarian governments using the same Internet freedom. …

TL;DR: In this article, the authors review research on key changes and trends in political information environments and assess their democratic implications, focusing on advanced postindustrial democracies and six concerns that are all closely linked to the dissemination and acquisition of political knowledge: (1) declining supply of political information, (2) declining quality of news, (3) increasing media concentration and declining diversity of news.
Abstract: During the last decennia media environments and political communication systems have changed fundamentally. These changes have major ramifications for the political information environments and the extent to which they aid people in becoming informed citizens. Against this background, the purpose of this article is to review research on key changes and trends in political information environments and assess their democratic implications. We will focus on advanced postindustrial democracies and six concerns that are all closely linked to the dissemination and acquisition of political knowledge: (1) declining supply of political information, (2) declining quality of news, (3) increasing media concentration and declining diversity of news, (4) increasing fragmentation and polarization, (5) increasing relativism and (6) increasing inequality in political knowledge.
