Data & Society — The Promises, Challenges, and Futures of Media Literacy Contemporary media literacy programs–commonly organized around the five main themes of youth participation, teacher training and curricular resources, parental support, policy initiatives, and evidence base construction–have demonstrated positive outcomes, particularly in the case of rapid responses to breaking news events, connecting critical thinking with behavior change, and evaluating partisan content. However, media literacy efforts continue to struggle with a lack of comprehensive evaluation data, with some research showing programs can have little-to-no impact for certain materials, or even lead to harmful overconfidence in assessing media content. Report authors Monica Bulger and Patrick Davison make five recommendations to guide the future of media literacy programming for educators, legislators, technologists, and philanthropists in the space.

Smart, dumb, candybar, flip, and brick: a visual history of mobile phones For most of their history, mobile phones have been shrinking. Small meant portable; it even, in the not too distant past, was a sort of status symbol. Remember Motorola’s runaway hit, the ultra-thin Razr? But something funny happened on the smartphone’s way to success. Years ago, your colleagues might have laughed at you if you couldn’t fit your phone in your pocket. If screen sizes continue to grow, you might want to invest in bigger pockets, a bulkier handbag, a man purse, or even a whole new way to carry your phone. Correction: An earlier version of this article stated that the Razr was Nokia’s runaway hit.

The future of data-driven decision-making Executive summary Today, successful digital enterprises in every industry require a digital strategy that recognises the value of data, and digital institutions now need to embrace big data too. Doing so will enable the institution to take advantage of emerging techniques and approaches such as Gartner's Insight Engines to generate actionable insights, improving equality and efficiency. Data strategies need to take account of how data is collected, processed, stored, and acted upon, as well as its governance, provenance, and quality concerns, and the data literacy of both staff and students. It is no longer enough for any organisation to rely solely upon data specialists working in silos. Data is everywhere. Of course, it is not sufficient simply to focus on exposing, collecting, storing, and sharing data in the raw. Learning analytics - the application of analytics in an educational context - is beginning to show real signs of success in areas such as student retention. Big data storage

What does the Internet look like? A multilayer graph model of the internet topology What does the Internet look like and how can data be navigated it around it most efficiently and effectively? That is the question that a paper detailing a multilayer graph model of the internet topology could answer. Details are reported in the International Journal of Networking and Virtual Organisations. Georg Tilch and Benjamin Fabian of the Humboldt University of Berlin, and Tatiana Ermakova of the Central Research Institute of Ambulatory Health Care, in Germany discuss how internet maps can be used to develop effective routing algorithms. The team has studied so-called traceroute datasets from various large-scale measurement campaigns such as iPlane, CAIDA, Carna, DIMES, RIPE Atlas and RIPE IPv6L. "By employing a broad diversity of graph measures, this study creates an exhaustive snapshot of the global internet topology," the team writes. More information: Georg Tilch et al.

How an ex-YouTube insider investigated its secret algorithm YouTube’s recommendation system draws on techniques in machine learning to decide which videos are auto-played or appear “up next”. The precise formula it uses, however, is kept secret. Aggregate data revealing which YouTube videos are heavily promoted by the algorithm, or how many views individual videos receive from “up next” suggestions, is also withheld from the public. Disclosing that data would enable academic institutions, fact-checkers and regulators (as well as journalists) to assess the type of content YouTube is most likely to promote. By putting a wall around its data, YouTube, which is owned by Google, protects itself from scrutiny. The ex-Google engineer said his method of extracting data from the video-sharing site could not provide a comprehensive or perfectly representative sample of videos that were being recommended.

Guide To Using Reverse Image Search For Investigations Reverse image search is one of the most well-known and easiest digital investigative techniques, with two-click functionality of choosing “Search Google for image” in many web browsers. This method has also seen widespread use in popular culture, perhaps most notably in the MTV show Catfish, which exposes people in online relationships who use stolen photographs on their social media. However, if you only use Google for reverse image searching, you will be disappointed more often than not. This guide will walk through detailed strategies to use reverse image search in digital investigations, with an eye towards identifying people and locations, along with determining an image’s progeny. Beyond Google The first and most important piece of advice on this topic cannot be stressed enough: Google reverse image search isn’t very good. As of this guide’s publication date, the undisputed leader of reverse image search is the Russian site Yandex. Yandex Bing Google Five Test Cases Isolated: Student
