It has recently become possible to study the dynamics of information diffusion in techno-social systems at scale, due to the emergence of online platforms, such as Twitter, with millions of users. One question that systematically recurs is whether information spreads according to simple or complex dynamics: does each exposure to a piece of information have an independent probability of a user adopting it (simple contagion), or does this probability depend instead on the number of sources of exposure, increasing above some threshold (complex contagion)? Most studies to date are observational and, therefore, unable to disentangle the effects of confounding factors such as social reinforcement, homophily, limited attention, or network community structure...

BACKGROUND: Adverse drug reactions (ADRs) are an important cause of morbidity and mortality. Classical Pharmacovigilance process is limited by underreporting which justifies the current interest in new knowledge sources such as social media. The Adverse Drug Reactions from Patient Reports in Social Media (ADR-PRISM) project aims to extract ADRs reported by patients in these media. We identified 5 major challenges to overcome to operationalize the analysis of patient posts: (1) variable quality of information on social media, (2) guarantee of data privacy, (3) response to pharmacovigilance expert expectations, (4) identification of relevant information within Web pages, and (5) robust and evolutive architecture...

Study Objectives: Social media (SM) use has been positively associated with disturbed sleep among young adults. However, previous studies have not elucidated the specific importance of SM use immediately before bed. We aimed to determine the independent association of SM use during the 30 minutes before bed and disturbed sleep while controlling for covariates including total SM use throughout the day. Methods: We assessed a nationally representative sample of 1763 US young adults aged 19-32...

OBJECTIVE: Alcohol media literacy (AML) programs have achieved positive results for alcohol prevention; however, gender may moderate program effectiveness. This study investigated gender differences for an Australian AML intervention. METHOD: Fifth and sixth graders ( N = 165), allocated to an intervention or wait-list control group, participated in an AML program. Student questionnaires were administered at three time points. RESULTS: The intervention resulted in significantly higher media deconstruction skills but did not lead to less preference for branded merchandise or greater understanding of persuasive intent, and these effects did not differ by gender...

PURPOSE: Bladder cancer (BC) is a current clinical and social problem. At diagnosis, most patients present non-muscle invasive tumors, characterized by a high recurrence rate, which could progress to muscle invasive disease and metastasis. Bone morphogenetic protein (BMP)-dependent signaling arising from stromal bladder tissue mediates urothelial homeostasis by promoting urothelial cell differentiation. However, the possible role of BMP ligands in BC is still unclear. EXPERIMENTAL DESIGN: Tumor and normal tissue from 68 patients with urothelial cancer were prospectively collected and analyzed for expression of BMP and macrophage markers...

We combine eight previously proposed measures to construct an index of political polarization among US adults. We find that polarization has increased the most among the demographic groups least likely to use the Internet and social media. Our overall index and all but one of the individual measures show greater increases for those older than 65 than for those aged 18-39. A linear model estimated at the age-group level implies that the Internet explains a small share of the recent growth in polarization.

BACKGROUND: The importance of health privacy protections in the era of the "Facebook Generation" has been called into question. The ease with which younger people share personal information about themselves has led to the assumption that they are less concerned than older generations about the privacy of their information, including health information. We explored whether survey respondents' views toward health privacy suggest that efforts to strengthen privacy protections as health information is moved online are unnecessary...

Margeret Hall, Simon Caton
Across social media platforms users (sub)consciously represent themselves in a way which is appropriate for their intended audience. This has unknown impacts on studies with unobtrusive designs based on digital (social) platforms, and studies of contemporary social phenomena in online settings. A lack of appropriate methods to identify, control for, and mitigate the effects of self-representation, the propensity to express socially responding characteristics or self-censorship in digital settings, hinders the ability of researchers to confidently interpret and generalize their findings...

A brief history of bovine tuberculosis (bTB) and its control in Great Britain (GB) is presented. Numerous diverse policies to control the disease in humans, cattle and wildlife have been pursued over the last 100 years and many millions of pounds have been spent. After notable success in reducing the incidence and prevalence of bTB in cattle in GB from the 1950s to the mid-1980s, the geographical spread of the disease and the number of cattle slaughtered have increased continually since that time, with a high point of bTB incidence in 2008...
