Download or read book Analysing Users Interactions with Khan Academy Repositories written by Sahar Yassine and published by Springer Nature. This book was released on 2021-11-15 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the need to explore user interaction with online learning repositories and the detection of emergent communities of users. This is done through investigating and mining the Khan Academy repository; a free, open access, popular online learning repository addressing a wide content scope. It includes large numbers of different learning objects such as instructional videos, articles, and exercises. The authors conducted descriptive analysis to investigate the learning repository and its core features such as growth rate, popularity, and geographical distribution. The authors then analyzed this graph and explored the social network structure, studied two different community detection algorithms to identify the learning interactions communities emerged in Khan Academy then compared between their effectiveness. They then applied different SNA measures including modularity, density, clustering coefficients and different centrality measures to assess the users’ behavior patterns and their presence. By applying community detection techniques and social network analysis, the authors managed to identify learning communities in Khan Academy’s network. The size distribution of those communities found to follow the power-law distribution which is the case of many real-world networks. Despite the popularity of online learning repositories and their wide use, the structure of the emerged learning communities and their social networks remain largely unexplored. This book could be considered initial insights that may help researchers and educators in better understanding online learning repositories, the learning process inside those repositories, and learner behavior.

Download or read book Statistical Rethinking written by Richard McElreath and published by CRC Press. This book was released on 2018-01-03 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical Rethinking: A Bayesian Course with Examples in R and Stan builds readers’ knowledge of and confidence in statistical modeling. Reflecting the need for even minor programming in today’s model-based statistics, the book pushes readers to perform step-by-step calculations that are usually automated. This unique computational approach ensures that readers understand enough of the details to make reasonable choices and interpretations in their own modeling work. The text presents generalized linear multilevel models from a Bayesian perspective, relying on a simple logical interpretation of Bayesian probability and maximum entropy. It covers from the basics of regression to multilevel models. The author also discusses measurement error, missing data, and Gaussian process models for spatial and network autocorrelation. By using complete R code examples throughout, this book provides a practical foundation for performing statistical inference. Designed for both PhD students and seasoned professionals in the natural and social sciences, it prepares them for more advanced or specialized statistical modeling. Web Resource The book is accompanied by an R package (rethinking) that is available on the author’s website and GitHub. The two core functions (map and map2stan) of this package allow a variety of statistical models to be constructed from standard model formulas.

Download or read book The Ladies Repository written by and published by . This book was released on 1850 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of this women's magazine originated with Samuel Williams, a Cincinnati Methodist, who thought that Christian women needed a magazine less worldly than Godey's Lady's Book and Snowden's Lady's Companion. Written largely by ministers, this exceptionally well-printed little magazine contained well-written essays of a moral character, plenty of poetry, articles on historical and scientific matters, and book reviews. Among western writers were Alice Cary, who contributed over a hundred sketches and poems, her sister Phoebe Cary, Otway Curry, Moncure D. Conway, and Joshua R. Giddings; and New England contributors included Mrs. Lydia Sigourney, Hannah F. Gould, and Julia C.R Dorr. By 1851, each issue published a peice of music and two steel plates, usually landscapes or portraits. When Davis E. Clark took over the editorship in 1853, the magazine became brighter and attained a circulation of 40,000. Unlike his predecessors, Clark included fictional pieces and made the Repository a magazine for the whole family. After the war it began to decline and in 1876 was replaced by the National Repository. The Ladies' Repository was an excellent representative of the Methodist mind and heart. Its essays, sketches, and poems, its good steel engravings, and its moral tone gave it a charm all its own. -- Cf. American periodicals, 1741-1900.

Download or read book Discoverability in Digital Repositories written by Liz Woolcott and published by Taylor & Francis. This book was released on 2023-04-04 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: While most discoverability evaluation studies in the Library and Information Science field discuss the intersection of discovery layers and library systems, this book looks specifically at digital repositories, examining discoverability from the lenses of system structure, user searches, and external discovery avenues. Discoverability, the ease with which information can be found by a user, is the cornerstone of all successful digital information platforms. Yet, most digital repository practitioners and researchers lack a holistic and comprehensive understanding of how and where discoverability happens. This book brings together current understandings of user needs and behaviors and poses them alongside a deeper examination of digital repositories around the theme of discoverability. It examines discoverability in digital repositories from both user and system perspectives by exploring how users access content (including their search patterns and habits, need for digital content, effects of outreach, or integration with Wikipedia and other web-based tools) and how systems support or prevent discoverability through the structure or quality of metadata, system interfaces, exposure to search engines or lack thereof, and integration with library discovery tools. Discoverability in Digital Repositories will be particularly useful to digital repository managers, practitioners, and researchers, metadata librarians, systems librarians, and user studies, usability and user experience librarians. Additionally, and perhaps most prominently, this book is composed with the emerging practitioner in mind. Instructors and students in Library and Information Science and Information Management programs will benefit from this book that specifically addresses discoverability in digital repository systems and services.

Available in PDF, EPUB and Kindle. Book excerpt: This Selected Issues paper examines how surges in global financial market volatility spill over to emerging market economies (EMs) including India. The results suggest that a surge in global financial market volatility is transmitted very strongly to key macroeconomic and financial variables of EMs, and the extent of its pass-through increases with the depth of external balance-sheet linkages between advanced countries and EMs. The paper also looks at food inflation, which has often been singled out as a key driver of India’s high and persistent inflation.
