Online political discussion is a growing form of political behavior and plays an important role in political deliberation in the new media age. This article examines "daily talk" as a type of political deliberation, and emphasizes two overlooked factors that influence online political discussion: direct government–citizen interactions and perceptions of the importance of new media for online political discussion. It also examines the moderation effects of perceived importance of new media on group communication and government–citizen interaction. Survey data analysis from the 2008 Civic Engagement survey from the Pew Internet & American Life Project (n = 2,251) reveals that citizens' interactions with both members of their political group and government officials have positive influences on the frequency of online political discussion. Meanwhile, the association between online political discussion and online group communication becomes stronger when one perceives that new media are less important as source of political information. The theoretical and policy implications of the findings are discussed.

This study refreshes the communication mediation model by integrating impacts of individual psychological traits (civic motivations and political efficacy) with the relationships between Chinese netizens' media news uses, civic expression/discussion and civic engagement in the model. The results of an online survey (N=490) indicated that new media and conventional media have indirect effects on civic engagement through different mediators. Specifically, reading news from the newspapers has a negative impact on motivations driven by emotion, but directly spurs political efficacy, civic discussion and engagement. By contrast, watching TV news encourages civic discussion, while browsing news online increases the likelihood of participatory behaviours, driven by emotions of anger or sadness. Pressure from social networks is positively related to civic engagement. Motivations of civic duties, emotion and political efficacy are positively related to online civic expression and discussion with social networks about public affairs, both of which are strongly associated with participatory behaviours.

Do social media help individuals without organisational memberships to engage more in politics or do they only facilitate political participation for those already involved? We examine how social media use and organisational membership jointly affect participation. Comparative surveys in Hong Kong and Taipei reveal that information sharing and virtual political engagement on social media mobilised users to engage in collective political actions. The influence of social media on individual-based participation is conditional on organisational membership, as reflected by the number of organisations joined. Organisational membership moderates the relationship between social media use and political behaviours differently in Hong Kong and Taipei.

As an interdisciplinary field, data-driven journalism integrates the intellectual origins of investigative journalism, computer-assisted reporting, and the emerging paradigm of computational social science. Studies of news production have revealed, however, that news professionals are reinforcing existing power structures via an interpretive community, where homophily-evoked social interactions—even in the social media context—create echo chambers and discussion fragmentation. Is the representation of data-driven journalism in the electronic public sphere breaking boundaries among people from different domains or does it resemble the existing power structure? This study adopts a network analytics approach and constructs a representational network among actors who joined the public discussion of data-driven journalism in the Twittersphere—the co-retweeted network—such that two accounts are connected if their tweets are retweeted by the same user. Public tweets containing search queries related to data-driven journalism published from February 2017 to February 2018 were collected with Twitter real-time streaming application programming interface (API). A co-retweeted network with 1,148 accounts was derived from verified accounts' retweeting posts. Results found that several communities emerged, and news organizations, nongovernmental and nonprofit professional organizations, and academic institutions were in the crucial positions of the network. The exponential random graph models (ERGMs) based on this network revealed the extent to which gender, geographical location, and institutional type of the users were associated with the tie-formation. This study documents the major actors who are discussing the subject of data-driven journalism and raises critical reflections toward the interdisciplinary collaboration in the production of public knowledge.

Recent increasing rates of COVID-19 cases, hospitalizations, and deaths among non-Hispanic Whites have led to declining rate ratios at a time of continuing high burden of COVID-19 in American Indian/ Alaska Native, Asian/Pacific Islander, African American, and Hispanic/Latino populations. The use of all epidemiological tools, including rate ratios and actual rates per 100,000 population, provides a more comprehensive assessment of the magnitude and trends of racial and ethnic disparities in COVID-19.Ethn Dis. 2022;32(2):109-112; doi:10.18865/ed.32.2.109

The present study challenges prevailing beliefs and research on the role of social media in supporting deliberation and an active public sphere. Based on a two-wave online panel survey ( n = 791) of the adult population of Hong Kong, as one case of a politically polarized society, we examine the degree to which individuals disconnect from those with whom they politically disagree with on social media. The analysis indicates that exposure to disagreement does indeed lead people to filter their information repertoire by disconnecting from those with whom they disagree. A moderated mediation analysis finds that political disagreement indirectly influenced activist participation through information repertoire filtration. However, in contrast to expectations, this effect was stronger when individuals had a lower level of affective polarization. Our findings underscore the value of focusing on the behavior of users to complement research on access to information about politics.

The Disparities Elimination through Coordinated Interventions to Prevent and Control Heart and Lung Disease Risk (DECIPHeR) research program, supported by the National Heart, Lung, and Blood Institute (NHLBI), focuses on developing and testing sustainable interventions to reduce heart and lung disease disparities. This perspective piece reflects on lessons learned during the planning phase (UG3) and outlines the accomplishments of the DECIPHeR Alliance. The article emphasizes the importance of a biphasic (UG3/UH3) funding mechanism, technical assistance, and collaborative subcommittees in achieving success. As DECIPHeR enters phase 2 (UH3), the article anticipates rigorously planned studies addressing social determinants of health and emphasizes the need for effective implementation strategies and equitable research frameworks. The Alliance's contributions, such as the IM4Equity framework, offer novel approaches to community-engaged health equity and implementation science research. The article explores future opportunities, including dissemination strategies, community engagement, and collaboration with diverse partners, to maximize DECIPHeR's impact on health disparities beyond cardiovascular and pulmonary health.

<p class="Default">The gap in educational attainment separating underrepresented minorities from Whites and Asians remains wide. Such a gap has sig­nificant impact on workforce diversity and in­clusion among cross-cutting Biomedical Data Science (BDS) research, which presents great opportunities as well as major challenges for addressing health disparities. This article pro­vides a brief description of the newly estab­lished National Institutes of Health Big Data to Knowledge (BD2K) diversity initiatives at four universities: California State University, Monterey Bay; Fisk University; University of Puerto Rico, Río Piedras Campus; and California State University, Fullerton. We em­phasize three main barriers to BDS careers (ie, preparation, exposure, and access to resources) experienced among those pioneer programs and recommendations for possible solutions (ie, early and proactive mentoring, enriched research experience, and data sci­ence curriculum development). The diversity disparities in BDS demonstrate the need for educators, researchers, and funding agencies to support evidence-based practices that will lead to the diversification of the BDS workforce. <em></em></p><p class="Default"><em>Ethn Dis. </em>2017;27(2):107-116; doi:10.18865/ed.27.2.107.</p>

<p>Achieving health equity requires that every person has the opportunity to attain their full health potential and no one is disadvantaged from achieving this potential because of social position or other socially determined circumstances. Inequity experienced by populations of lower socioeconomic status is reflected in differences in health status and mortality rates, as well as in the distribution of disease, disability and illness across these population groups. This article gives an overview of the health inequities literature associated with heart, lung, blood and sleep (HLBS) disorders. We present an ecological framework that provides a theoretical foundation to study late-stage T4 translation research that studies implementation strategies for proven effective interventions to address health inequities. <em>Ethn Dis. </em>2016;26(3):387-394; doi:10.18865/ ed.26.3.387 </p>
