Hi Reddit, I’m Tom Smith, MD for the UK’s Data Science Campus as part of the Office for National Statistics. I have 20 years’ experience using data and analysis to improve public services and am a life-long data addict. I have a PhD in computational neuroscience and robotics, an MSc in knowledge-based systems and an MA in theoretical physics. I’m currently Chair of the Advisory Board to the United Nations Global Platform for big data & official statistics, Member of Council for the UK Royal Statistical Society, and previously chair of the Environment Agency Data Advisory Group, vice-chair of the Royal Statistical Society Official Statistics section, and a member of the Open Data User Group ministerial advisory group to Cabinet Office. Since the Campus was founded in 2017 we have been working on a huge range of projects including: - using tax returns, ship tracking data and road traffic sensor data to allow early identification of large economic changes; - exploring what internet traffic peaks and troughs can tell us about our lives; - using satellite imagery to detect surface water and assess changes over time, for rapid detection of emerging issues; - launching a hub focused on data science and AI for International Development, located at the Department for International Development (DfID), near Glasgow. - supporting ONS, government and public sector organisations to increase their data science capability. We’re aiming to have 500 trained data science practitioners for UK government by 2021. I’ll be here to talk about statistics, data and making the world a better place from 3-5pm GMT today.

Twitter is a useful medium for the exchange of ideas, but it is not well suited to a thorough exposition of complex topics. In one recent exchange, I engaged author and journalist Peter Hitchens (@clarkemicah) on the relative harms of alcohol and cannabis, a discussion he later dissected in his blog (http://dailym.ai/13Dc1Rv). Having repeatedly attempted without success to post a reply on his blog, I have elected to do so here.
Intraclass correlation (ICC) is one of the most commonly misused indicators of interrater reliability, but a simple step-by-step process will get it right. In this article, I provide a brief review of reliability theory and interrater reliability, followed by a set of practical guidelines for the calculation of ICC in SPSS.
Boyer’s framework of scholarship was published before significant growth in digital technology. As more digital products are produced by medical educators, determining their scholarly value is of increasing importance. This scoping systematic review developed a taxonomy of digital products and determined their fit within Boyer’s framework of scholarship. We conducted a broad literature search for descriptions of digital products in the medical literature in July 2013 using Medline, EMBASE, ERIC, PSYCHinfo, and Google Scholar. A framework analysis categorized each product using Boyer’s model of scholarship, while a thematic analysis defined a taxonomy of digital products. 7422 abstracts were found and 524 met inclusion criteria. Digital products mapped primarily to the scholarship of teaching (85.4%) followed by integration (7.6%), application (5.5%), and discovery (1.5%). A taxonomy of 19 categories was defined. Web-based or computer assisted learning (41%) was described most frequently. We found that digital products are well described in medical literature and fit into Boyer’s framework of scholarship and proposed a taxonomy of digital products that parallel traditional forms of the scholarship of teaching and learning. This research should inform the development of tools to examine the impact and quality of digital products.
This article is about whether the factors which drive online sharing of non-scholarly content also apply to academic journal titles. It uses Altmetric scores as a measure of online attention to articles from Frontiers in Psychology published in 2013 and 2014. Article titles with result-oriented positive framing and more interesting phrasing receive higher Altmetric scores, i.e., get more online attention. Article titles with wordplay and longer article titles receive lower Altmetric scores. This suggests that the same factors that affect how widely non-scholarly content is shared extend to academia, which has implications for how academics can make their work more likely to have more impact.
This article examines the U.S. Army’s Comprehensive Soldier Fitness (CSF) program from a scientific, ethical, and pragmatic viewpoint. CSF is one of the largest single applications of psychological research in history, intended to develop “resilience” in every U.S. Army soldier. I highlight several areas where the available information about the program either suggests the likelihood of specific problems, or is insufficient to allow the research community to evaluate the effectiveness of CSF independently of the claims made by its originators and assurances given by other non-disinterested parties. In particular, I question (a) whether a program based on resiliency training for school-aged children can hope to address the serious mental trauma, including PTSD, faced by soldiers deployed to war zones; (b) whether the instruments used to measure the performance of the program are reliable, valid, and appropriate for the circumstances in which they are being used, and (c) whether the design and delivery of the program takes sufficient account of the conflicting real-world demands placed on the individuals involved. I conclude that the program appears to have a number of potentially problematic aspects that require wider scrutiny from psychological researchers and practitioners.

Blog and podcast use is rising among learners in the health professions. The lack of a standardized method to assess the quality of these resources prompted a research agenda aimed at solving this problem. Through a rigorous research process, a list of 151 quality indicators for blogs and podcasts was formed and subsequently refined to elicit the most important quality indicators. These indicators are presented as Quality Checklists to assist with quality appraisal of medical blogs and podcasts.
Hello, Reddit! We are a team of conservationists and scientists here to discuss artisanal and small-scale mining, its surprising importance to some of our most beloved possessions, and its effects on biodiversity. Let’s discuss! Artisanal and small-scale mining (ASM)—the mining of metals and minerals by hand, often using tools as simple as a hammer and a pick—-is an enormous part of our industrial supply chain. In fact, ASM is the main source of income for over 40 million people world wide, and is responsible for between 15–20% of all the world’s mineral and metal production. ASM produces huge percentages of the world’s gold, tin, and cobalt supplies, which, as you may know, are all absolutely crucial ingredients to one of our most important possessions- our smart phones. As things stand, there are some serious drawbacks to artisanal and small scale mining. Notably, ASM requires a lot of water to clean the mined materials before they’re ready for sale, and in some cases, numerous poisonous solvents must be used as well. What results is contaminated water, decreased biodiversity, and birth defects—and these are just some of the problems. For these reasons, we’ve been extremely interested lately in potential technological, logistical, and political solutions that could improve the lives of ASM workers and protect their environments. We’re here today with some ideas of our own, but certainly not all the answers. We hope that we can have a lively discussion about artisanal mining, really dig into the issues surrounding it, and maybe even unearth some possible solutions. Today’s discussion is in collaboration with Conservation X Labs, a D.C. based conservation non-profit that acts as an incubator to help innovators and organizations bring great conservation ideas to life and get them out into the world where they can make a difference for the people who need them. Conservation X Labs is putting up $750,000 dollars in prize money in hopes of finding solutions to improve lives of ASM workers and protect their environments. Our discussion-panel guests today are: Alex Dehgan (u/Alex_Dehgan): I am CEO and co-founder of Conservation X Labs. I recently served as the Chief Scientist at USAID, with rank of Assistant Administrator, and co-founded the Global Development Lab. I am also the Chanler Innovator at Duke University and served as Duke’s inaugural David Rubenstein Fellow. Prior to USAID, I worked in multiple positions within the Office of the Secretary, and the Bureau of Near Eastern Affairs, at the Dept. of State, where I used science and conservation as a diplomatic tool for engagement with countries in the Islamic world, including Iran. I also hold a J.D. from the University of California, Hastings, and a B.S. from Duke University, and am the author of The Snow Leopard Project and Other Adventures in Warzone Conservation. Luis E. Fernandez (u/Luis_E_Fernandez): I am the Executive Director of the Amazon Scientific Innovation Center (CINCIA) and an Assistant Professor of Research in the Department of Biology at Wake Forest University. I am a tropical ecologist, as well as an expert in the dynamics and impact of environmental mercury in areas where artisanal mining is common.
