Abstract Current estimates of COVID-19 prevalence are largely based on symptomatic, clinically diagnosed cases. The existence a large number undiagnosed infections hampers population-wide investigation viral circulation. Here, we use longitudinal wastewater analysis to track SARS-CoV-2 dynamics in at major urban treatment facility Massachusetts, between early January and May 2020. was first detected March 3. Viral titers increased exponentially from mid-March mid-April, after which they...
This paper investigates online propaganda strategies of the Internet Research Agency (IRA)—Russian “trolls”—during 2016 U.S. presidential election. We assess claims that IRA sought either to (1) support Donald Trump or (2) sow discord among public by analyzing hyperlinks contained in 108,781 tweets. Our results show although accounts promoted links both sides ideological spectrum, “conservative” trolls were more active than “liberal” ones. The also shared content across social media...
To what extent does the YouTube recommendation algorithm push users into echo chambers, ideologically biased content, or rabbit holes? Despite growing popular concern, recent work suggests that is not pushing these chambers. However, existing research relies heavily on use of anonymous data collection account for personalized nature algorithm. We asked a sample real to install browser extension downloaded list videos they were recommended. instructed start an assigned video and then click...
We analyze the spread of Donald Trump’s tweets that were flagged by Twitter using two intervention strategies—attaching a warning label and blocking engagement with tweet entirely. find while on certain limited their diffusion, messages we examined labels further than those without labels. Additionally, had been blocked remained popular Facebook, Instagram, Reddit, being posted more often garnering visibility either labeled or received no at all. Taken together, our results emphasize...
Abstract We present a method for estimating the ideology of political YouTube videos. The subfield as latent variable has often focused on traditional actors such legislators, while more recent work used social media data to estimate ordinary users, elites, and sources. build this video. First, we start with matrix Reddit posts linking videos apply correspondence analysis place those in an ideological space. Second, train language model estimated ideologies training labels, enabling us not...
The rise of audio-as-data in social science research accentuates a fundamental challenge: establishing reproducible and reliable methodologies to guide this emerging area study. In study, we focus on the reproducibility preparation methods computational communication evaluate accuracy popular tools. We analyze automated transcription phonology tools applied 200 episodes conservative talk shows hosted by Rush Limbaugh Alex Jones. Our findings reveal that tested are highly accurate. However,...
Skepticism about the outcome of 2020 presidential election in United States led to a historic attack on Capitol January 6th, 2021 and represents one greatest challenges America's democratic institutions over century. Narratives fraud conspiracy theories proliferated fall 2020, finding fertile ground across online social networks, although little is know extent drivers this spread. In article, we show that users who were more skeptical election's legitimacy likely be recommended content...
Species residing across elevational gradients display adaptations in response to environmental changes such as oxygen availability, ultraviolet radiation, and temperature. Here, we study genomic variation, gene expression, long-term adaptation Tibetan Partridge (Perdix hodgsoniae) populations the gradient of Plateau. We generated a high-quality draft genome used it carry out downstream population transcriptomic analysis. The P. hodgsoniae various elevations were genetically distinct, their...
Scientists across disciplines often use data from the internet to conduct research, generating valuable insights about human behavior. However, as generative AI relying on massive text corpora becomes increasingly valuable, platforms have greatly restricted access through official channels. As a result, researchers will likely engage in more web scraping collect data, introducing new challenges and concerns for researchers. This paper proposes comprehensive framework social science research...
We present a method for estimating the ideology of political YouTube videos. As online media increasingly influences how people engage with politics, so does importance quantifying such research. The subfield as latent variable has often focused on traditional actors legislators, while more recent work used social data to estimate ordinary users, elites, and sources. build this by developing ideologies videos, an important subset media, based their accompanying text metadata. First, we take...
Discusses Mary Fortune's contributions to the Australian Journal, 'a trailblazer for production of colonial literature'. Focusing on essays 'The Tressless Bride' (6 June 1868) and Last Scene' (November 1970), Brown shows how work exemplifies Journal's 'breadth views gender'.
There is scant quantitative research describing Nextdoor, the world's largest and most important hyperlocal social media network. Due to its localized structure, Nextdoor data are notoriously difficult collect work with. We build multiple datasets that allow us generate descriptive analyses of platform's offline contexts online content. first create a comprehensive dataset all neighborhoods joined with U.S. Census data, which we analyze at community-level (block-group). Our findings suggests...
A challenge for public opinion surveys is achieving representativeness of respondents across demographic groups. We test the extent to which ideological alignment with a survey's sponsor shapes differential partisan response and users' choice whether participate in research study on Facebook. While use Facebook advertisements recruitment has increased recent years offers potential benefits, it can yield difficulties recruiting politically representative samples. recruit short survey through...
Early career researchers (ECR) in communication and media research face increasing problems stressors due to systemic challenges academia, including the precarity of being an ECR politicization targeting researchers. For studying harmful content online (HCO), research-related trauma (RRT) can compound these stressors. In this study, we present results from interviews with 18 ECRs studies adjacent disciplines HCO. We find frequently experience RRT content, pressure superiors conduct on...
Abstract A case study is provided describing Lloyd's Register's development of a set Key Performance Indicators (KPIs) for Process Safety Management (PSM) an oil and gas client. The process described in this paper along with discussion how the KPIs were developed designed to support client gaining clearer picture their current performance drive improvement that performance. This includes number are introduced, sequencing introduction KPIs, associated implementation requirements, reporting...
We test whether candidates move to the extremes before a primary but then return center for general election appeal different preferences of each electorate. Incumbents are now more vulnerable challenges than ever as social media offers viable pathway fundraising and messaging challengers, while homogeneity districts has reduced competitiveness. To assess candidates' ideological trajectories, we estimate revealed ideology 2020 congressional (incumbents, their open seat candidates) after...
