The tenth-anniversary edition of a foundational text in digital media and learning, examining new media practices that range from podcasting to online romantic breakups. Hanging Out, Messing Around, and Geeking Out, first published in 2009, has become a foundational text in the field of digital media and learning. Reporting on an ambitious three-year ethnographic investigation into how young people live and learn with new media in varied settings-at home, in after-school programs, and in online spaces-it presents a flexible and useful framework for understanding the ways that young people engage with and through online platforms: hanging out, messing around, and geeking out, otherwise known as HOMAGO. Integrating twenty-three case studies-which include Harry Potter podcasting, video-game playing, music sharing, and online romantic breakups-in a unique collaborative authorship style, Hanging Out, Messing Around, and Geeking Out combines in-depth descriptions of specific group dynamics with conceptual analysis. Since its original publication, digital learning labs in libraries and museums around the country have been designed around the HOMAGO mode and educators have created HOMAGO guidebooks and toolkits. This tenth-anniversary edition features a new introduction by Mizuko Ito and Heather Horst that discusses how digital youth culture evolved in the intervening decade, and looks at how HOMAGO has been put into practice. This book was written as a collaborative effort by members of the Digital Youth Project, a three-year research effort funded by the John D. and Catherine T. MacArthur Foundation and conducted at the University of California, Berkeley, and the University of Southern California.

Toxicology – the study of the adverse effects of chemicals on living organisms is the cornerstone to all aspects of chemical safety and knowledge of the subject is needed in a wide spectrum of fields from the chemical industry to medicine, emergency services, forensics, and regulatory science. Toxicology involves the study of symptoms, mechanisms, treatments and detection of poisoning ... especially the poisoning of people. The many problems arising from a poor understanding of toxicology and its applications in hazard communication and chemical safety motivated the author's training courses and webinars, leading to this valuable book. Providing a practical and accessible guide, A Practical Guide to Toxicology and Human Health Risk Assessment enables readers to quickly build up knowledge and understanding of toxicology and its use in hazard identification, which is a fundamental part of chemical risk assessment. The book also covers current toxicological testing strategies and the use of physicochemical test data in hazard identification and exposure assessment. Examples are provided throughout the book to highlight important issues along with a summary of the key points that have been covered in each of the respective chapters. The book concludes with a listing of online resources on toxicology and risk assessment.

This book provides a guide to the use and meaning of toxicological and ecological information in the paper industry. For example, the information provided by suppliers of paper chemicals to paper mills is analysed in detail. This allows for greater understanding by users and therefore awareness of the possible implications of handling a given chemical with respect to its impact on the working environment, the final product and the environment beyond the mill. The information currently available is collected, summarised and systematised so that users bombarded with inconsistent Safety Data Sheets can make intelligent use of them or can ask sensible questions of their suppliers. Emphasis is on providing guidance on how to find a commercially realistic path between over evaluation and under evaluation of potential health and environmental risks.
