<p>Cross‐sector relationship building is an important strategy in corporate social responsibility initiatives, and communicating cross‐sector relationships on social media can help raise the visibility of collaborative relationships. A noticeable gap in the literature is how social media enables and constrains the formation patterns of cross‐sector connections. To understand how businesses communicate their relationships with government agencies and nonprofits about social issues on social media, we propose a theoretical framework that centers public attention as a critical resource and considers different sectors' interests in the COVID‐19 issue. We tested this framework with a nationally representative sample of 1,980 organizations on Twitter. The analysis reveals that the increase in public attention to the COVID‐19 issue was accompanied by a greater likelihood of cross‐sector ties. Specifically, firms severely affected by COVID‐19 were more likely to build ties with government agencies, and the increase in public attention also drove firms to build more ties with nonprofits, especially advocacy nonprofits. Our findings suggest managers of social media communication should observe the volatile public attention and design communicative strategies accordingly.</p>

Objectives: This study examined the health discussion networks (HDNs) of people with inflammatory bowel disease (IBD). We sought to test if HDN characteristics were associated with IBD management self-efficacy outcomes. Methods: We recruited a sample of adults with IBD (N = 112) in December 2020 to take an online survey. Participants listed up to five people (alters) who they discussed their health with, and we used those data to construct individual HDNs. Participants provided demographic information about alters, and characterized alter by relationship, closeness, and support provided. We used multivariable regression to examine associations of HDN characteristics with IBD symptoms, remission, and emotions management self-efficacy outcomes. Results: Participants reported data for 412 alters (mean HDN size: 3.68). Alters were mostly friends (40%) or family members (36%); few were healthcare workers (6%). In multivariable analyses, HDN size was associated with remission and emotions management self-efficacy (ps <.05), and the amount of support offered by alters was associated with emotions management self-efficacy (p <.05). Discussion: HDN size and alter support variables were associated with some IBD management self-efficacy outcomes among our study sample. These findings provide empirical evidence about HDNs among people with IBD and support the notion that disease management is a collective effort.

The interorganizational relationship communication literature has identified homophily – the tendency for actors to form ties with similar others – as a mechanism predictive of tie formation among ...

While communication research on interorganizational homophily has grown, little is known about how issue homophily—defined here as the propensity to form ties based on shared issue priorities—influences interorganizational relationships in civil society. Our theoretical framework brings together homophily research and issue niche theory to explore the potential influence issues have on interorganizational network tie formation. Our empirical case is the network of civil society organizations focused on government reform in Malaysia. Using data gathered from a survey with organizational leaders (n = 90), exponential random graph models with binary and valued data explored how two types of homophily are associated with tie formation and cooperation in interorganizational relationships. Key findings from the study include that more important issues appear to drive tie formation and levels of cooperation in the network, only specific issues lead to homophilous ties, and issue homophily does not lead to greater levels of cooperation among civil society organizations.

Investigations of networked public spheres often examine the structures of online platforms by studying users' interactions. These works suggest that users' interactions can lead to cyberbalkani-zation when interlocutors form homophilous communities that typically have few connections to others with opposing ideologies. Yet, rather than assuming communities are isolated, this study examines community-level interactions to reveal how communities in online discourses are more interdependent than previously theorized. Specifically, we examine how such interactions influence the evolution of topics overtime in source and target communities. Our analysis found that (a) the size of a source community (the community that initiates interactions) and a target community (the community that receives interactions), (b) the stability of the source community, and (c) the volume of mentions from a source community to a target community predicts the level of influence one community has on another's discussion topics. We argue this has significant theoretical and practical implications. Lay Summary Political discussions online, especially those in the United States, seem to range between harmonious discussions of likeminded people and heated debates that end with few, if any, who have changed their minds. Researchers have often examined these balkanized/polarized situations by studying online communities as isolated echo chambers of opinion. Our study focuses on the interactions between online communities who have different worldviews. We examine communities engaged in the global refugee crisis. We consider how the inter-community interactions influence the agenda of the respective communities. Our longitudinal analysis on the one hand

Consumer engagement has become a critical component to many brands' relationship and promotional efforts. Empirical studies have documented the psychological elements that can drive consumers to engage with brands. However, there is a knowledge gap regarding how consumer engagement is influenced by the social environment consumers are embedded in. Taking an egocentric network approach, this study explores the social network factors that affect different dimensions of consumers' online engagement behaviors with a brand.,An online survey with an egocentric network design was employed, and 263 completed responses were collected from college students in US. The dimensionality of consumer engagement was validated using exploratory factor analysis. The hypotheses were tested through three sets of hierarchical regression models.,The results suggest that consumer engagement with a brand was partially shaped by the attributes of consumers' brand discussion networks that emerge from their conversations about a brand with others in everyday life. Specifically, the size, heterogeneity, and density to consumers' discussion networks were associated with certain engagement behaviors.,This study introduces a novel type of network method known as egocentric network analysis to explore and investigate the social network antecedents to consumer engagement behavior. It advances the conception of consumer engagement as a dynamic process influencing and is influenced by consumers' social interactions rather than merely a product of their psychological mechanisms. The study contributes to a social network approach to examining and conceptualizing consumer engagement.

Background The genetic architecture of birth size may differ geographically and over time. We examined differences in the genetic and environmental contributions to birthweight, length and ponderal index (PI) across geographical-cultural regions (Europe, North America and Australia, and East Asia) and across birth cohorts, and how gestational age modifies these effects. Methods Data from 26 twin cohorts in 16 countries including 57 613 monozygotic and dizygotic twin pairs were pooled. Genetic and environmental variations of birth size were estimated using genetic structural equation modelling. Results The variance of birthweight and length was predominantly explained by shared environmental factors, whereas the variance of PI was explained both by shared and unique environmental factors. Genetic variance contributing to birth size was small. Adjusting for gestational age decreased the proportions of shared environmental variance and increased the propositions of unique environmental variance. Genetic variance was similar in the geographical-cultural regions, but shared environmental variance was smaller in East Asia than in Europe and North America and Australia. The total variance and shared environmental variance of birth length and PI were greater from the birth cohort 1990-99 onwards compared with the birth cohorts from 1970-79 to 1980-89. Conclusions The contribution of genetic factors to birth size is smaller than that of shared environmental factors, which is partly explained by gestational age. Shared environmental variances of birth length and PI were greater in the latest birth cohorts and differed also across geographical-cultural regions. Shared environmental factors are important when explaining differences in the variation of birth size globally and over time.

© 2017 The Author(s). Background: HIV testing for marginalized populations is critical to controlling the HIV epidemic. However, the HIV testing rate among men who have sex with men (MSM) in China remains low. Crowdsourcing, the process of shifting individual tasks to a group, has been increasingly adopted in public health programs and may be a useful tool for spurring innovation in HIV testing campaigns. We designed a multi-site study to develop a crowdsourced HIV test promotion campaign and evaluate its effectiveness against conventional campaigns among MSM in China. Methods: This study will use an adaptation of the stepped wedge, randomized controlled trial design. A total of eight major metropolitan cities in China will be randomized to sequentially initiate interventions at 3-month intervals. The intervention uses crowdsourcing at multiple steps to sustain crowd contribution. Approximately 1280 MSM, who are 16 years of age or over, live in the intervention city, have not been tested for HIV in the past 3 mmonths, and are not living with HIV, will be recruited. Recruitment will take place through banner advertisements on a large gay dating app along with other social media platforms. Participants will complete one follow-up survey every 3 months for 12 months to evaluate their HIV testing uptake in the past 3 months and secondary outcomes including syphilis testing, sex without condoms, community engagement, testing stigma, and other related outcomes. Discussion: MSM HIV testing rates remain poor in China. Innovative methods to promote HIV testing are urgently needed. With a large-scale, stepped wedge, randomized controlled trial our study can improve understanding of crowdsourcing's long-term effectiveness in public health campaigns, expand HIV testing coverage among a key population, and inform intervention design in related public health fields.

<h3>Background</h3><p>Recent state budget crises have dramatically reduced funding for state-sponsored antitobacco media campaigns. If campaigns are associated with reduced smoking, such cuts could result in long-term increases in state health care costs.</p><h3>Methods</h3><p>Commercial ratings data on mean audience exposure to antitobacco advertising that appeared on network and cable television across the largest 75 media markets in the United States for 1999 through 2000 were combined with nationally representative survey data from school-based samples of youth in the contiguous 48 states. Multivariate regression models were used to analyze associations between mean exposure to state antitobacco advertising and youth smoking-related beliefs and behaviors, controlling for individual and environmental factors usually associated with youth smoking and other televised tobacco-related advertising.</p><h3>Results</h3><p>Mean exposure to at least 1 state-sponsored antitobacco advertisement in the past 4 months was associated with lower perceived rates of friends’ smoking (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.58-0.88), greater perceived harm of smoking (OR, 1.25; 95% CI, 1.11-1.42), stronger intentions not to smoke in the future (OR, 1.43; 95% CI, 1.17-1.74), and lower odds of being a smoker (OR, 0.74; 95% CI, 0.63-0.88).</p><h3>Conclusions</h3><p>To our knowledge, this study is the first to explore the potential impact of state-sponsored antitobacco media campaigns while controlling for other tobacco-related advertising and other tobacco control policies. State-sponsored antitobacco advertising is associated with desired outcomes of greater antitobacco sentiment and reduced smoking among youth. Recent cuts in these campaigns may have future negative health and budgetary consequences.</p>
