Using Instagram to Engage with (Potential) Consumers: A study of Forbes Most Valuable Brands’ Use of Instagram

With over 800 million monthly users, Instagram has become one of the most popular social networking sites utilized by individuals and businesses alike. Guided by interactivity theory, the current study identifies connections between the posting behaviour of popular brands on Instagram and audience engagement. Instagram posts (N = 710) from brands on the Forbes Most Valuable Brands list were coded for image type and the presence of brand-related and social content. Using an individualized engagement score for each post, results found audiences were most responsive when images featured products and logos together and when social content appears in captions. Findings of this study are useful to marketing strategists aiming to capitalize on this platform

Effect of early tranexamic acid administration on mortality, hysterectomy, and other morbidities in women with post-partum haemorrhage (WOMAN): an international, randomised, double-blind, placebo-controlled trial

Background Post-partum haemorrhage is the leading cause of maternal death worldwide. Early administration of tranexamic acid reduces deaths due to bleeding in trauma patients. We aimed to assess the effects of early administration of tranexamic acid on death, hysterectomy, and other relevant outcomes in women with post-partum haemorrhage. Methods In this randomised, double-blind, placebo-controlled trial, we recruited women aged 16 years and older with a clinical diagnosis of post-partum haemorrhage after a vaginal birth or caesarean section from 193 hospitals in 21 countries. We randomly assigned women to receive either 1 g intravenous tranexamic acid or matching placebo in addition to usual care. If bleeding continued after 30 min, or stopped and restarted within 24 h of the first dose, a second dose of 1 g of tranexamic acid or placebo could be given. Patients were assigned by selection of a numbered treatment pack from a box containing eight numbered packs that were identical apart from the pack number. Participants, care givers, and those assessing outcomes were masked to allocation. We originally planned to enrol 15 000 women with a composite primary endpoint of death from all-causes or hysterectomy within 42 days of giving birth. However, during the trial it became apparent that the decision to conduct a hysterectomy was often made at the same time as randomisation. Although tranexamic acid could influence the risk of death in these cases, it could not affect the risk of hysterectomy. We therefore increased the sample size from 15 000 to 20 000 women in order to estimate the effect of tranexamic acid on the risk of death from post-partum haemorrhage. All analyses were done on an intention-to-treat basis. This trial is registered with ISRCTN76912190 (Dec 8, 2008); ClinicalTrials.gov, number NCT00872469; and PACTR201007000192283. Findings Between March, 2010, and April, 2016, 20 060 women were enrolled and randomly assigned to receive tranexamic acid (n=10 051) or placebo (n=10 009), of whom 10 036 and 9985, respectively, were included in the analysis. Death due to bleeding was significantly reduced in women given tranexamic acid (155 [1·5%] of 10 036 patients vs 191 [1·9%] of 9985 in the placebo group, risk ratio [RR] 0·81, 95% CI 0·65–1·00; p=0·045), especially in women given treatment within 3 h of giving birth (89 [1·2%] in the tranexamic acid group vs 127 [1·7%] in the placebo group, RR 0·69, 95% CI 0·52–0·91; p=0·008). All other causes of death did not differ significantly by group. Hysterectomy was not reduced with tranexamic acid (358 [3·6%] patients in the tranexamic acid group vs 351 [3·5%] in the placebo group, RR 1·02, 95% CI 0·88–1·07; p=0·84). The composite primary endpoint of death from all causes or hysterectomy was not reduced with tranexamic acid (534 [5·3%] deaths or hysterectomies in the tranexamic acid group vs 546 [5·5%] in the placebo group, RR 0·97, 95% CI 0·87-1·09; p=0·65). Adverse events (including thromboembolic events) did not differ significantly in the tranexamic acid versus placebo group. Interpretation Tranexamic acid reduces death due to bleeding in women with post-partum haemorrhage with no adverse effects. When used as a treatment for postpartum haemorrhage, tranexamic acid should be given as soon as possible after bleeding onset.

U.S. television reporting of the Arab Spring: A study of ABC, CBS and NBC

Reporting of international conflict has implications for understanding, political action, and policy formation. This means media coverage can influence the outcomes of conflict. This study investigated reporting of the Arab Spring conflicts by U.S. television networks (ABC, CBS, and NBC). The study examined the time frame between the onset of the uprising and February 29, 2012 when dictators were unseated in Tunisia, Egypt, Libya, and Yemen. Agenda-setting and media framing theory were used to analyze transcripts (N = 316) for dominant issues, sources used, frames and, social media. Results of the study corroborate existing research regarding conflict reporting. Coverage was mostly episodic and dominated by violence, however, attention was paid to the role of social media in overthrowing regimes, violent acts of regime brutality, and democracy. Core causes of the uprising received only marginal coverage. Ordinary domestic citizens were used most frequently as sources. Other findings applicable to U.S. media coverage are presented

An Angry, Hopeful, or Efficacious Citizen: Information, Emotion, and Participation in an Emerging Democracy

A growing body of research has examined how access to political information via digital media contributes to democratic participation in new or transitory democracies. Much of this work focuses on cognitive factors, such as political efficacy and civic knowledge, while less attention is paid to the role of emotion. Drawing on insights from the orientation–stimuli–orientation–response (O-S-O-R) and anger activism model (AAM), this study proposes and tests a model of political information seeking and participation using a national survey of adult Nigerians ( N   =  600). Findings provide support for the model and highlight potential pathways through which political information may enhance participation

Where\u27s the fracking bias?: Contested media frames and news reporting on shale gas in the United States

© 2019 Hydraulic fracturing, often called fracking, is a drilling technique that accesses previously inaccessible oil/gas reserves. Although the process could aid U.S. energy independence, it is controversial and public opinion is divided. Guided by agenda-setting and framing, this study content analyses news coverage of fracking (N = 524) across cable networks (CNN, Fox News, MSNBC). Results show cable news lacks substance and relies on thematic framing. While all networks failed to provide factual information, issue-related topics discussed and sources used vary ideologically. Theoretical and practical implications, which include the potential for priming audiences and influencing future behaviors and judgments, are discussed
