The National Digital Public Library Is Launched! by Robert Darnton The Digital Public Library of America, to be launched on April 18, is a project to make the holdings of America’s research libraries, archives, and museums available to all Americans—and eventually to everyone in the world—online and free of charge. How is that possible? In order to answer that question, I would like to describe the first steps and immediate future of the DPLA. But before going into detail, I think it important to stand back and take a broad view of how such an ambitious undertaking fits into the development of what we commonly call an information society. Speaking broadly, the DPLA represents the confluence of two currents that have shaped American civilization: utopianism and pragmatism.

Crap Detection, A 21st Century Literacy One of the 21st Century Literacies Howard Rheingold talks about is Crap Detection. Though I think the need for critical thinking or analysis has been around a long time, it has become increasingly important as Alan Shapiro demonstrates in his article, The Essential Skill of Crap Detecting So how do you teach or learn this essential skill? Two librarians at Dominican University have put together this CRAP test Impact Factor and alternative metrics Facts & figures A total of 1,681 Springer journals are listed in the 2016 Thomson Reuters Journal Citation Reports® (JCR).Virchows Archiv (The Official Journal of the European Society of Pathology) continually publishing since 1847 is our oldest journal listed in the JCR.40 Springer journals were added to the JCR 2016 and have an impact factor for the first time.52% of Springer journals increased their impact factor from 2014 to 2015.Over half of Palgrave Macmillan’s JCR 2016 listed journals enjoyed an increased impact factor (with an average increase of 30%). These high-quality journals within business & economics, humanities and social sciences are now part of the Springer journal portfolio.A total of 185 BMC journals are listed in the JCR 2016; 9 for the first time and 92 with increasing impact factor.

Flow of Information The Timeline: A look at linear time and information: from the occurrence of an event, era, social movement or discovery, ...to the documentation of evidence relating to this event, era, social movement, etc.to how the evidence is disseminatedand how researchers (and term paper writers) can find this documentation One Day - Days Later Chromosome Mapping: Human Genome Research in Progress The Human Genome Project was completed in 2003. One of the key research areas was Chromosome Mapping. This page details that research. Mapping is the construction of a series of chromosome descriptions that depict the position and spacing of unique, identifiable biochemical landmarks, including some genes, that occur on the DNA of chromosomes.

MoCap Toolbox The MoCap Toolbox is a Matlab® toolbox that contains functions for the analysis and visualization of motion capture data. The toolbox is mainly aimed for the analysis of music-related movement, but might be useful in other areas of study as well. It supports the generic .c3d file format, the .tsv data format produced by the Qualisys Motion Capture system, the .mat file format produced by the Qualisys Motion Capture system, the .bvh format, and the .wii format produced by the WiiDataCapture software. To use the toolbox, you need the Matlab software. Before using it, the toolbox has to be added in the Matlab path variable.

Advice for effective analytical reasoning Good list of cognitive biases Wikipedia List of Cognitive Biases (Please read this before continuing below.) After reading through the list, one wonders how people ever get anything right. That's called the "cognitive biases bias," or maybe the "skepticism bias" or "paralysis by analysis." There's also the "bias bias," where lists of cognitive biases are used as rhetorical weapons to attack any analysis, regardless of the quality of the analysis. The previous sentence then could be countered by describing it as an example of the "bias bias bias," and so on in an boring infinite regress of tu quoque disputation, or "slashdot."

NOVA The 100-Year-Old Idea That Could Change Flight Inspired by birds, bats, and the Wright brothers, engineers are building the next breakthrough in aviation. From NOVA Next | Feb 22, 2017 Key Brain Regions Found To Be Smaller in People With ADHD Questionnaire design Perhaps the most important part of the survey process is the creation of questions that accurately measure the opinions, experiences and behaviors of the public. Accurate random sampling and high response rates will be wasted if the information gathered is built on a shaky foundation of ambiguous or biased questions. Creating good measures involves both writing good questions and organizing them to form the questionnaire. Questionnaire design is a multistage process that requires attention to many details at once. Designing the questionnaire is complicated because surveys can ask about topics in varying degrees of detail, questions can be asked in different ways, and questions asked earlier in a survey may influence how people respond to later questions.

Evaluating Arguments and Checking Sources Ruth Fremson/The New York TimesTheodore Ogunbiyi-Roche, 10, drank a large soda in Times Square in Aug., 2012, as New Yorkers debated Mayor Bloomberg’s plan to prohibit sales of large sugary drinks. Students in Rita Tamalavage’s class used this and related articles for a research project. Go to related article » Here is another in our Great Ideas From Readers series. If you’ve used The Times for teaching and learning and would like to see your idea in our blog, write in and tell us what you’ve done.
