Book Description
This book introduces recent development of technologies for mine waste management in China. For hard rock mines, the main mine wastes are tailings, and the tailings can be disposed above-ground and/or underground. The technology of consolidated tailings stockpile (CTS) that disposes tailings above-ground is introduced, and the application of this technology is also demonstrated. Besides, the technology of cemented tailings (or paste) backfill (CTB or CPB) which deals with tailings underground is also discussed. The properties of CTB materials and the utilization of CTB technology are described and analyzed. For coal mines, the main mine wastes are coal gangue and fly ash. The technology of cemented coal gangue-fly ash backfill (CGFB) that manages coal mine waste underground is presented. The THMC coupling properties of CGFB materials are investigated, which can contribute to a better design of stable, durable and environmentally friendly CGFB mixtures. The application of CGFB technology in a coal mine is also presented. This book, which systematically reviews and discusses the development of mine waste management technologies in China, is expected to provide readers comprehensive information about mine waste management.

Book Description
The only how-to guide offering a unified, systemic approach to acquiring, cleaning, and managing data in R Every experienced practitioner knows that preparing data for modeling is a painstaking, time-consuming process. Adding to the difficulty is that most modelers learn the steps involved in cleaning and managing data piecemeal, often on the fly, or they develop their own ad hoc methods. This book helps simplify their task by providing a unified, systematic approach to acquiring, modeling, manipulating, cleaning, and maintaining data in R. Starting with the very basics, data scientists Samuel E. Buttrey and Lyn R. Whitaker walk readers through the entire process. From what data looks like and what it should look like, they progress through all the steps involved in getting data ready for modeling. They describe best practices for acquiring data from numerous sources; explore key issues in data handling, including text/regular expressions, big data, parallel processing, merging, matching, and checking for duplicates; and outline highly efficient and reliable techniques for documenting data and recordkeeping, including audit trails, getting data back out of R, and more. The only single-source guide to R data and its preparation, it describes best practices for acquiring, manipulating, cleaning, and maintaining data Begins with the basics and walks readers through all the steps necessary to get data ready for the modeling process Provides expert guidance on how to document the processes described so that they are reproducible Written by seasoned professionals, it provides both introductory and advanced techniques Features case studies with supporting data and R code, hosted on a companion website A Data Scientist's Guide to Acquiring, Cleaning and Managing Data in R is a valuable working resource/bench manual for practitioners who collect and analyze data, lab scientists and research associates of all levels of experience, and graduate-level data mining students.

Book Description
How do early modern media underlie today’s digital creativity? In Cut/Copy/Paste, Whitney Trettien journeys to the fringes of the London print trade to uncover makerspaces and collaboratories where paper media were cut up and reassembled into radical, bespoke publications. Bringing these long-forgotten objects back to life through hand-curated digital resources, Trettien shows how early experimental book hacks speak to the contemporary conditions of digital scholarship and publishing. As a mixed-media artifact itself, Cut/Copy/Paste enacts for readers what Trettien argues: that digital forms have the potential to decenter patriarchal histories of print. From the religious household of Little Gidding—whose biblical concordances and manuscripts exemplify protofeminist media innovation—to the queer poetic assemblages of Edward Benlowes and the fragment albums of former shoemaker John Bagford, Cut/Copy/Paste demonstrates history’s relevance to our understanding of current media. Tracing the lives and afterlives of amateur “bookwork,” Trettien creates a method for identifying and comprehending hybrid objects that resist familiar bibliographic and literary categories. In the process, she bears witness to the deep history of radical publishing with fragments and found materials. With many of Cut/Copy/Paste’s digital resources left thrillingly open for additions and revisions, this book reimagines our ideas of publication while fostering a spirit of generosity and inclusivity. An open invitation to cut, copy, and paste different histories, it is an inspiration for students of publishing or the digital humanities, as well as anyone interested in the past, present, and future of creativity.

Book Description
A declaration of independence, and a call for systemic change, from the generation that will be most impacted by climate change. If anyone doubted the potential political power of the Millennial generation, Bernie Sanders' campaign put it in the spotlight. Are We Screwed? makes clear that the ardor for change defines this generation, especially when it comes to climate change, and they are willing to consider options that their elders might think naive and impractical, rejecting a capitalism that cares only about profit and a political system riven by false ideology. In telling the stories of his contemporaries around the globe, in describing how they think and the many ways they are already effecting change, Geoff Dembicki documents a historic shift in values and a corresponding re-thinking of how social change can happen.As of this year, the millennial generation (18- to 34-year-olds) will become North America's largest demographic. It is also the generation that has lived with the looming reality of global warming and will be most affected by its impacts. In vividly reported dispatches from Beijing to Paris, from San Francisco to New York, Dembicki examines what millennial responses to climate change look like and how they are shaping our future. He also provides an essential perspective on how climate change is intensifying generational tensions and shifts in society. In the process, a portrait of a generation emerges that goes a long way toward re-branding it in ways that are positive and full of hope for the future.
