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.
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.

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.
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.

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.
Hi Reddit! Today’s discussion is coming to us from the National Academy of Sciences, Engineering and Medicine (NASEM) and is a collaboration between r/science, LabX, and the Water, Science and Technology Board! We are panel of diverse water science professionals ready to answer your questions about all things related to drinking water. Water is a ubiquitous phenomenon! But its visual abundance—from its constant flow out of taps and fountains to the immensity of our oceans—can mask the fact that 1 in 7 people worldwide lack access to safe drinking water (that’s over 1 billion people!). Furthermore, in places like New Orleans or The Netherlands, water can seem like an impending threat without the proper means to safely contain it, or productively incorporate it into our daily lives. The broader water/society interface raises questions about drinking water’s vulnerability to climate change and society’s vulnerability to ageing infrastructure for adequate and safe sourcing, treatment, and distribution. Poor drinking water quality can result from pollution from sources such as industrial waste, agricultural runoff, corrosion of lead from distribution pipes, or treatment facility contamination by man-made materials such as polyfluoroalkyl substances (PFAS). Emerging innovations in grey/green infrastructure, stewardship programs to reduce man-made contaminants, desalination technology, and international efforts to increase access to safe water on a global scale might help preserve and increase Earth’s water supply and society’s value of it. All of these issues, and more, are on our collective radar and we look forward to discussing them with you. Ask us anything! Our discussion panel guests today are: Will Logan (u/Will_Logan_ICIWaRM) is currently the Director at the International Center for Integrated Water Resources Management (ICIWaRM), which is part of the U.S. Army Corps of Engineers. Previously, Will was the Science Attaché for the US Mission to UNESCO and he served for almost a decade on the Water, Science, and Technology Board at the National Academies of Sciences. Will holds a Ph.D. in Earth Sciences/Hydro-geology from Waterloo University and was an Assistant Professor of Hydro-geology at George Washington University. Ellen de Guzman (u/Ellen_de_Guzman) is currently the Senior Water Officer in the Middle East and North Africa Bureau at USAID. Ellen has managed projects spanning rural reconstruction, humanitarian and disaster response, alternative livelihoods, food security, agriculture, water and sanitation. Prior to USAID, Ellen worked for the National Academies of Sciences, where she provided policy research support to develop federal policies on managing subsurface water contamination, the Clean Water Act, sustainable water and environmental management in the California Bay-Delta, and invasive species in ballast water. Jin Shin (u/Jin_Shin_WSSC) is currently the Water Quality Division Manager at WSSC (Washington Suburban Sanitary Commission), where he has worked for nearly 15 years. The WSSC is one of the largest water and wastewater utilities in the nation, with a service area that spans nearly 1,000 square miles in Prince George’s and Montgomery counties in Maryland.

Hi reddit! We’re a group of scientists and advocates who believe that the traditional genetics research model is outdated. We think that people who participate in genetic studies should be involved in decision-making, that research projects should collaborate, that samples should be diverse, and that studies should use real world data. We need these changes to improve our ability to discover treatments and cures for diseases. But at the same time, researchers also need to ensure participant privacy, data security, and give participants the chance to weigh in on and directly benefit from research- medically, informationally, and financially. Let’s discuss! With us today are an array of researchers and leaders from a variety of genetics backgrounds working with a company, LunaPBC, on these questions. Dawn Barry (u/Dawn_Barry): I’m the President and Co-founder at LunaPBC, Board Chair at Alzheimer’s Association San Diego/Imperial Chapter, and former VP Applied Genomics at Illumina.

Until then, it was our pleasure chatting with you!
Hi reddit! This month the UN is holding its Climate Action Summit, it is New York City’s Climate Week next week, today is the Global Climate Strike, earlier this month was the Asia Pacific Climate Week, and there are many more local events happening. Since climate change is in the news a lot let’s talk about it! We’re a panel of experts who study and communicate about climate change’s causes, impacts, and solutions, and we’re here to answer your questions about it! Is there something about the science of climate change you never felt you fully understood? Questions about a claim you saw online or on the news? Want to better understand why you should care and how it will impact you? Or do you just need tips for talking to your family about climate change at Thanksgiving this year? We can help! Here are some general resources for you to explore and learn about the climate: AAAS just released a report with case studies and videos of how communities and companies (and individuals) in the US are working with scientists to respond to climate change called “How We Respond.” NASA: Vital Signs of the Planet National Academies of Sciences: Climate Change Evidence and Causes National Geographic: Seven things to know about Climate Change Today’s guests are: Emily Cloyd (u/BotanyAndDragons): I’m the director for the American Association for the Advancement of Science Center for Public Engagement with Science and Technology, where I oversee programs including How We Respond: Community Responses to Climate Change (just released!), the Leshner Leadership Institute, and the AAAS IF/THEN Ambassadors, and study best practices for science communication and policy engagement. Prior to joining AAAS, I led engagement and outreach for the Third National Climate Assessment, served as a Knauss Marine Policy Fellow at the National Oceanic and Atmospheric Administration, and studied the use of ecological models in Great Lakes management. I hold a Master’s in Conservation Biology (SUNY College of Environmental Science and Forestry) and a Bachelor’s in Plant Biology (University of Michigan), am always up for a paddle (especially if it is in a dragon boat), and last year hiked the Tour du Mont Blanc. Jeff Dukes (u/Jeff_Dukes): My research generally examines how plants and ecosystems respond to a changing environment, focusing on topics from invasive species to climate change. Much of my experimental work seeks to inform and improve climate models. The center I direct has been leading the Indiana Climate Change Impacts Assessment (INCCIA); that’s available at IndianaClimate.org. You can find more information about me at https://web.ics.purdue.edu/~jsdukes/lab/index.html, and more information about the Purdue Climate Change Research Center at http://purdue.edu/climate. Hussein R. Sayani (u/Hussein_Sayani): I’m a climate scientist at the School of Earth and Atmospheric Science at Georgia Institute of Technology. I develop records of past ocean temperature, salinity, and wind variability in the tropical Pacific by measuring changes in the chemistry of fossil corals. These past climate records allow us to understand past climate changes in the tropical Pacific, a region that profoundly influences temperature and rainfall patterns around the planet, so that we can improve future predictions of global and regional climate change. Jessica Moerman (u/Jessica_Moerman): Hi reddit! My name is Jessica Moerman and I study how climate changed in the past - before we had weather stations. How you might ask? I study the chemical fingerprints of geologic archives like cave stalagmites, lake sediments, and ancient soil deposits to discover how temperature and rainfall varied over the last several ice age cycles. I have a Ph.D. in Earth and Atmospheric Sciences from the Georgia Institute of Technology and have conducted research at Johns Hopkins University, University of Michigan, and the Smithsonian National Museum of Natural History. I am now a AAAS Science and Technology Policy Fellow working on climate and environmental issues. Our guests will be joining us throughout the day (primarily in the afternoon Eastern Time) to answer your questions and discuss!
