Drawing upon theories of landscape and performance, this work weaves together existing tourism literature with new scholarship to forge a geographically informed theory of tourism. Such a theory integrates the ways in which places are co-produced, circulated, interpreted, experienced, and performed for and by tourists, tourism boards, and even as everyday spaces. Bringing together theories of ritual, Peircean semiotics, ideology, and performance, the authors blend the often separate literatures of tourism sites and touristic practices. Whereas most tourism texts focus on a part of the 'tourism equation'-the tourism site, or the tourist experience-a geographic theory of tourism brings these constituent parts together in thinking about notions of place. Place processes are central to geography as well as tourism studies because tourism facilitates encounters with distinct locations. As this book argues, considering tourism as performative draws disparate areas of tourism theory together to better understand the ways tourism happens in and across places.
The Comprehensive Sourcebook of Bacterial Protein Toxins, Fourth Edition, contains chapters written by internationally known and well-respected specialists. This book contains chapters devoted to individual toxins, as well as chapters that consider the different applications of these toxins. Considerable progress has been made in understanding the structure, function, interaction and trafficking into cells, as well as mechanism of action of toxins. Bacterial toxins are involved in the pathogenesis of many bacteria, some of which are responsible for severe diseases in human and animals, but can also be used as tools in cell biology to dissect cellular processes or used as therapeutic agents. Novel recombinant toxins are already proposed in the treatment of some diseases, as well as new vaccines. Alternatively, certain toxins are also considered as biological weapons or bioterrorism threats. Given the multifaceted aspects of toxin research and the multidisciplinary approaches adopted, toxins are of great interest in many scientific areas from microbiology, virology, cell biology to biochemistry and protein structure. This new edition is written with a multidisciplinary audience in mind and contains 5 new chapters that reflect the latest research in this area. Other chapters have been combined, deleted and fully revised as necessary to deliver relevant and valuable content. - Descriptions of relevant toxins as well as representative toxins of the main bacterial toxin families to allow for a better comparison between them - Focused chapters on toxin applications and common properties or general features of toxins
Highway Engineering: Planning, Design, and Operations, Second Edition, presents a clear and rigorous exposition of highway engineering concepts, including project development and the relationship between planning, operations, safety and highway types. The book includes important topics such as corridor selection and traverses, horizontal and vertical alignment, design controls, basic roadway design, cross section elements, intersection and interchange design, and the integration of new vehicle technologies and trends. It also presents end of chapter exercises to further aid understanding and learning. This edition has been fully updated with the current design policies and reference manuals essential for highway, transportation, and civil engineers who are required to work to these standards. - Provides an updated resource on current design standards from the Highway Capacity Manual and the Green Book - Covers fundamental traffic flow relationships and traffic impact analysis, collision analysis, road safety audits and advisory speeds - Presents the latest applications and engineering considerations for highway planning, design and construction
