Throughout history obscenity has not really been about sex but about degradation. Sexual depictions have been suppressed when they were seen as lowering the status of humans, furthering our distance from the gods or God and moving us toward the animals. In the current era, when we recognize ourselves and both humans and animals, sexual depiction has lost some of its sting. Its degrading role has been replaced by hate speech that distances groups, whether based on race, ethnicity, gender, or sexual orientation, not only from God but from humanity to a subhuman level. In this original study of the relationship between obscenity and hate speech, First Amendment specialist Kevin W. Saunders traces the legal trajectory of degradation as it moved from sexual depiction to hateful speech. Looking closely at hate speech in several arenas, including racist, homophobic, and sexist speech in the workplace, classroom, and other real-life scenarios, Saunders posits that if hate speech is today’s conceptual equivalent of obscenity, then the body of law that dictated obscenity might shed some much-needed light on what may or may not qualify as punishable hate speech.

Organic photovoltaics (OPV) are a new generation of solar cells with the potential to offer very short energy pay back times, mechanical flexibility and significantly lower production costs compared to traditional crystalline photovoltaic systems. A weakness of OPV is their comparative instability during operation and this is a critical area of research towards the successful development and commercialization of these 3rd generation solar cells. Covering both small molecule and polymer solar cells, Stability and Degradation of Organic and Polymer Solar Cells summarizes the state of the art understanding of stability and provides a detailed analysis of the mechanisms by which degradation occurs. Following an introductory chapter which compares different photovoltaic technologies, the book focuses on OPV degradation, discussing the origin and characterization of the instability and describing measures for extending the duration of operation. Topics covered include: Chemical and physical probes for studying degradation Imaging techniques Photochemical stability of OPV materials Degradation mechanisms Testing methods Barrier technology and applications Stability and Degradation of Organic and Polymer Solar Cells is an essential reference source for researchers in academia and industry, engineers and manufacturers working on OPV design, development and implementation.

Desertification offers a comprehensive overview of the subject and clearly emphasizes the link between local and global desertification processes and how past and current policy has affected arid environments and their populations. This text adequately applies the research undertaken during the last 15 years on the topic. Desertification has become increasingly politicized and there is a need to present and explain the facts from a global perspective. This book tackles the issues surrounding desertification in a number of ways from differing scales (local to global), processes (physical to human), the relationship of desertification to current global development and management responses at different scales. Desertification has been mainstreamed and integrated into other areas of concern and has consequently been ignored as a cross cutting issue. The book redresses this balance. Making use of much original data and information that has been undertaken by many scientists andpractitioners during the last decade in different parts of the world, Desertification, Land Degradation and Sustainability is organised according to the principles of adaptive management and hierarchy theory and clearly explains desertification within a framework of evolving and interacting physical and socio-economic systems. In addition to research data the book also draws from the National Action Plans of different countries, the IPCC Fourth Assessment on Climate Change and the Millennium assessments. Clearly structured throughout, the content of the book is organised at different scales; local, regional and global. It also specifically explains processes linking top-down and bottom- up interactions and has a strong human component. The historical, cultural and physical context is also stressed. Clearly organised into the following distinct sections: a) Concepts and processes b) Data c) Impacts d) Responses e) Case studies. This text is essential for anyone studying desertification as part of an earth and environmental science degree.

This book describes nerve agents and vesicants, their decomposition and their degradation products' chemistry as well as their toxicity including a list of detection techniques of nerve agents and their degradation products. This book will present their history, toxicity, comparison between different sample preparation methods, separation techniques, and detection methods all together in a short, easy to read book, tied together by a single group doing the writing and the editing to assure smooth transition from chapter to chapter, with sufficient Tables and literature references for the reader who looks to further detail.The text will illustrate the pluses and minuses of the various techniques with sufficient references for the reader to obtain extensive detail.

This book provide a series of designs, materials, characterization and modeling, that will help create safer and stronger structures in coastal areas. The authors take a look at the different materials (porous, heterogeneous, concrete…), the moisture transfers in construction materials as well as the degradation caused by external attacks and put forth systems to monitor the structures or evaluate the performance reliability as well as degradation scenarios of coastal protection systems

“Degradation process” refers to many types of reliability models, which correspond to various kinds of stochastic processes used for deterioration modeling. This book focuses on the case of a univariate degradation model with a continuous set of possible outcomes. The envisioned univariate models have one single measurable quantity which is assumed to be observed over time. The first three chapters are each devoted to one degradation model. The last chapter illustrates the use of the previously described degradation models on some real data sets. For each of the degradation models, the authors provide probabilistic results and explore simulation tools for sample paths generation. Various estimation procedures are also developed.
