Going rogue: what scientists can learn about Twitter communication from “alt” government accounts

The inauguration of President Trump in the United States led to the active restriction of science communication from federal agencies, resulting in the creation of many unofficial “alt” Twitter accounts to maintain communication. Alt accounts had many followers (e.g., 15 accounts had \u3e 100,000) and received a large amount of media attention, making them ideal for better understanding how differences in messaging can affect public engagement with science on microblogging platforms. We analyzed tweets produced by alt and corresponding official agency accounts to compare the two groups and determine if specific features of a tweet made them more likely to be retweeted or liked to help the average scientist potentially reach a broader audience on Twitter. We found adding links, images, hashtags, and mentions, as well as expressing angry and annoying sentiments all increased retweets and likes. Evidence-based terms such as “peer-review” had high retweet rates but linking directly to peer-reviewed publications decreased attention compared to popular science websites. Word choice and attention did not reflect official or alt account types, indicating topic is more important than source. The number of tweets generated and attention received by alt accounts has decreased since their creation, demonstrating the importance of timeliness in science communication on social media. Together our results show potential pathways for scientists to increase efficacy in Twitter communications

A roadmap to integrated digital public health surveillance: The vision and the challenges

The exponentially increasing stream of real time big data produced by Web 2.0 Internet and mobile networks created radically new interdisciplinary challenges for public health and computer science. Traditional public health disease surveillance systems have to utilize the potential created by new situationaware realtime signals from social media, mobile/sensor networks and citizens' participatory surveillance systems providing invaluable free realtime event-based signals for epidemic intelligence. However, rather than improving existing isolated systems, an integrated solution bringing together existing epidemic intelligence systems scanning news media (e.g., GPHIN, MedISys) with real-time social media intelligence (e.g., Twitter, participatory systems) is required to substantially improve and automate early warning, outbreak detection and preparedness operations. However, automatic monitoring and novel verification methods for these multichannel event-based real time signals has to be integrated with traditional case-based surveillance systems from microbiological laboratories and clinical reporting. Finally, the system needs effectively support coordination of epidemiological teams, risk communication with citizens and implementation of prevention measures. However, from computational perspective, signal detection, analysis and verification of very high noise realtime big data provide a number of interdisciplinary challenges for computer science. Novel approaches integrating current systems into a digital public health dashboard can enhance signal verification methods and automate the processes assisting public health experts in providing better informed and more timely response. In this paper, we describe the roadmap to such a system, components of an integrated public health surveillance services and computing challenges to be resolved to create an integrated real world solution

AAPOR Report on Big Data

In recent years we have seen an increase in the amount of statistics in society describing different phenomena based on so called Big Data. The term Big Data is used for a variety of data as explained in the report, many of them characterized not just by their large volume, but also by their variety and velocity, the organic way in which they are created, and the new types of processes needed to analyze them and make inference from them. The change in the nature of the new types of data, their availability, the way in which they are collected, and disseminated are fundamental. The change constitutes a paradigm shift for survey research.There is a great potential in Big Data but there are some fundamental challenges that have to be resolved before its full potential can be realized. In this report we give examples of different types of Big Data and their potential for survey research. We also describe the Big Data process and discuss its main challenges

iCrawl: Improving the Freshness of Web Collections by Integrating Social Web and Focused Web Crawling

Researchers in the Digital Humanities and journalists need to monitor, collect and analyze fresh online content regarding current events such as the Ebola outbreak or the Ukraine crisis on demand. However, existing focused crawling approaches only consider topical aspects while ignoring temporal aspects and therefore cannot achieve thematically coherent and fresh Web collections. Especially Social Media provide a rich source of fresh content, which is not used by state-of-the-art focused crawlers. In this paper we address the issues of enabling the collection of fresh and relevant Web and Social Web content for a topic of interest through seamless integration of Web and Social Media in a novel integrated focused crawler. The crawler collects Web and Social Media content in a single system and exploits the stream of fresh Social Media content for guiding the crawler.Comment: Published in the Proceedings of the 15th ACM/IEEE-CS Joint Conference on Digital Libraries 201

A framework for measuring quality in the emergency department

There is increasing concern that medical care is of variable quality, with variable outcomes, safety, costs and experience for patients. Despite substantial efforts to improve patient safety, some studies suggest little evidence of reductions in adverse events. Furthermore, there is limited agreement about what outcomes are expected and whether increased expenditure results in a real improvement in outcome or experience. In emergency medicine, many countries have developed specific indicators to help drive improvements in patient care. Most of these are time based and there is a lack of consensus regarding which indicators are high priority and what an appropriate framework for measuring quality should look like

Crowdsourced Rumour Identification During Emergencies

When a significant event occurs, many social media users leverage platforms such as Twitter to track that event. Moreover, emergency response agencies are increasingly looking to social media as a source of real-time information about such events. However, false information and rumours are often spread during such events, which can influence public opinion and limit the usefulness of social media for emergency management. In this paper, we present an initial study into rumour identification during emergencies using crowdsourcing. In particular, through an analysis of three tweet datasets relating to emergency events from 2014, we propose a taxonomy of tweets relating to rumours. We then perform a crowdsourced labeling experiment to determine whether crowd assessors can identify rumour-related tweets and where such labeling can fail. Our results show that overall, agreement over the tweet labels produced were high (0.7634 Fleiss Kappa), indicating that crowd-based rumour labeling is possible. However, not all tweets are of equal difficulty to assess. Indeed, we show that tweets containing disputed/controversial information tend to be some of the most difficult to identify

Data science strategy for injury and violence prevention

Injuries and violence are the leading causes of death in the United States for children, adolescents, and adults ages 18 to 44 years and rank in the top 10 causes of death for persons 45 years or older. In recent years, rates of deaths due to many forms of injury and violence\u2014drug overdose, suicide, homicide, road traffic crashes, and falls\u2014have increased, leading to recent declines in life expectancy in the United States. Beyond rising mortality, injuries and violence contribute to substantial morbidity as well as social and economic costs each year.Preventing injury and violence is a public health imperative given the significant impact on individuals, families, and communities across the United States. However, primary challenges to rapidly addressing these public health problems include limitations of both public health data as well as prevention and response capabilities. Lack of timely information, inability to identify emerging health threats, limited capacity to target services, increasingly prevalent health misinformation, declining participation in and lack of representativeness of traditional data systems, and fragmentation of electronic health records and clinical data systems are examples of the challenges facing contemporary public health efforts.A growing body of research now indicates that application of novel data and data science tools, methods, and techniques can help address critical public health needs, including injury and violence prevention and related issues such as social determinants of health and health equity. Academic research has focused, for example, on the use of novel data sources such as internet search queries to assess disease-related trends in real-time, natural language processing to study electronic health records and other systems with unstructured text, machine learning to improve prevention programming, network analysis to better understand mortality risk, online surveys to improve data timeliness and response rates, and interactive data visualization to improve communication and dissemination of scientific findings.Although data science is an emerging field, academic, industry, and governmental organizations have typically defined it by two consistent features: 1) a multidisciplinary approach that blends methodological techniques from computer science, statistics, and various subject matter domains and 2) a focus on large, complex, or otherwise novel data sources.For the purposes of public health and injury and violence prevention, the National Center for Injury Prevention and Control (Injury Center) defines population-health data science as a multidisciplinary approach combining traditional epidemiologic methods and contemporary computer science techniques, with a particular focus on large and complex data sources, to improve the measurement and prevention of injury and violence in communities.Suggested Citation: Centers for Disease Control and Prevention.
