Human Scent Evidence

Human Scent Evidence

During the last decade a significant number of scientific studies have supported the use of human scent as a biometric tool and indicator of the presence or absence of an individual at a crime scene. These findings even extend to conducting scent identification line-ups with suspects. Human Scent Evidence focuses on some of these recent advances in the use of human scent as forensic evidence and as an identifier. Topics include:Various theories of human odor productionThe variability stability and persistence of human scent Historical aspects of the use of human scent in police work in the United States and internationallyCurrent trends in scent collection techniques including devices materials and storage protocolsChemical aspects of the evaluation of human scent including instrumental methods for odor detection and analysisThe legal significance of human scent evidence resultsCanine scent work from multiple search categories as described in the Scientific Working Group on Dog and Orthogonal detector Guidelines (SWGDOG)Human scent evidence may be of critical use in many cases where other types of evidence such as DNA fingerprints or fibers are not readily available. As such it can be a valuable tool in forensic investigations. With examples from North and South America and Europe this book draws upon an extensive literature review of past and current research and is enhanced with findings from the authors’ own research. It concludes with a glimpse of the future direction of human scent evidence in the forensic field and its application as a biometric and diagnostic tool.

Detector Dogs and Scent Movement How Weather Terrain and Vegetation Influence Search Strategies

Detector Dogs and Scent Movement How Weather Terrain and Vegetation Influence Search Strategies

Dogs detect scent from a source that is carried to them in a plume by the wind. The most important tool for a detector dog handler to have on searches is a knowledge of scent plume movement or scent dynamics (the science of scent movement). Such knowledge resides primarily in scientific journals that are largely inaccessible to detector dog handlers and written in language that is difficult to understand. Detector Dogs and the Science of Scent Movement: A Handler’s Guide to Environments and Procedures retrieves reviews and interprets the results of pertinent scientific research on scent dynamics and presents these results in terms that are easier for handlers to understand. Information on the physiology of the dog’s nose their sense of smell and the properties of scent provide the essential information on the process of scenting. The composition of training aids for explosives narcotics human remains and other sources is discussed. Recommendations are made on the use of training aids their placement during training and the resulting availability of scent. Potential problems and handler errors in the use of training aids are also examined. The characteristics of scent plumes and how wind influences their movement are a key focus of the book. The primary task for the handler is to get the dog into the scent plume so that the dog can detect the scent and follow it to the source the handler seeks. As such a knowledge of scent and scent plume movement will vastly improve the ability of the handler to accomplish this task. The influence of weather and physical settings such as terrain vegetation ground cover soil and water on scent movement are examined in detail. Strategies for searching detecting and locating sources in all physical settings are presented. Specific effects associated with hills and mountains fields and forests bare soils and soils covered by vegetation different soil types and lakes and rivers are examined in detail. This includes specific recommendations are made about weather and physical settings that result in higher probability of success on searches. Detector Dogs and the Science of Scent Movement will be a vital resource for K9 handles in the private and public sectors—including in Homeland Security law enforcement and military settings—as well as a useful guide for lawyers forensic and investigative professionals who need to better understand K9 operations. | Detector Dogs and Scent Movement How Weather Terrain and Vegetation Influence Search Strategies

What is this thing called Metaethics?

What makes something morally right? Where do our ethical standards come from? Are they relative to cultures or timeless and universal? Are there any objective moral facts? What is goodness? If there are moral facts how do we learn about them? What do we mean when we say someone ought to do something? These are all questions in metaethics the branch of ethics that investigates the status of morality the nature of ethical value the possibility of ethical knowledge and the meaning of ethical statements. To the uninitiated it can appear abstract and far removed from its two more concrete cousins ethical theory and applied ethics yet it is one of the fastest-growing and most exciting areas of ethics. What is this thing called Metaethics? demystifies this important subject and is ideal for students coming to it for the first time. Beginning with a brief overview of metaethics and the development of a conceptual toolkit Matthew Chrisman introduces and assesses the following key topics: ethical reality: including questions about naturalism and non-naturalism moral facts and the distinction between realism and antirealism ethical language: does language represent reality? What mental states are expressed by moral statements? moral psychology: the theory of motivation and the connection between moral judgement and motivation moral knowledge: intuitionist and coherentist moral epistemologies and theories of objectivity and relativism in metaethics prominent metaethical theories: naturalism nonnaturalism error-theory and expressivism new directions in metaethics including non-traditional theories thick ethical concepts and extensions to metaepistemology and metanormative theory The Second Edition has been completely revised and updated throughout. This includes a new thematic organization of the core chapters many new examples a newly written final chapter including discussion of thick ethical concepts and all-things-considered normativity updated references to recent scholarly literature improved learning resources an expanded glossary of terms and much more. Additional features such as chapter summaries questions of understanding and suggestions for further reading make What is this thing called Metaethics? an ideal introduction to metaethics.

What is this thing called Philosophy of Language?

What is this thing called Philosophy of Language?

Philosophy of language explores some of the most abstract yet most fundamental questions in philosophy. The ideas of some of the subject's great founding figures such as Gottlob Frege Ludwig Wittgenstein and Bertrand Russell as well as of more recent figures such as Saul Kripke and Hilary Putnam are central to a great many philosophical debates to this day. In this clear and carefully structured introduction to the subject Gary Kemp explains the following key topics: the basic nature of philosophy of language its concepts and its historical development Frege’s theory of sense and reference; Russell's theory of definite descriptions Wittgenstein's Tractatus Ayer and the Logical Positivists recent perspectives including Kripke Kaplan and Putnam; arguments concerning necessity indexicals rigid designation and natural kinds The pragmatics of language including speech-acts presupposition and conversational implicature Davidson’s theory of language the ‘principle of charity’ and the indeterminacy of interpretation puzzles surrounding the propositional attitudes (sentences which ascribe beliefs to people) Quine’s naturalism and its consequences for philosophy of language. The challenges presented by the later Wittgenstein Contemporary directions including contextualism fictional objects and the phenomenon of slurs This second edition has been thoroughly revised to include new key topics and updated material. Chapter summaries annotated further reading and a glossary make this an indispensable introduction to those teaching philosophy of language and will be particularly useful for students coming to the subject for the first time. | What is this thing called Philosophy of Language?

Predator-Prey Dynamics The Role of Olfaction

Predator-Prey Dynamics The Role of Olfaction

Humans being visually oriented are well versed in camouflage and how animals hide from predators that use vision to locate prey. However many predators do not hunt by sight; they hunt by scent. This raises the question: do survival mechanisms and behaviors exist which allow animals to hide from these olfactory predators? If so what are they and how do they work? Predator-Prey Dynamics: The Role of Olfaction examines environmental as well as biological and behavioral elements of both predators and prey to answer gaps in our current knowledge of the survival dynamics of species. Beginning with a thorough look at the mechanics of olfaction the author explains how predators detect locate and track their prey using odor trails on the ground or odor plumes in the air. Understanding the physics of airflow is the next step to understanding the potential for manipulating and masking scent. While a bush may conceal an animal visually from a predator it will not protect an animal from a predator using olfaction. To hide from the latter an animal needs to hide in locations where turbulence and updrafts will disperse its scent. The book addresses tradeoffs that animals must make given their dual needs to hide from predators and to procure food and water. Studies of mammalian and avian behavior provide examples on the actual use and efficacy of olfactory camouflage tactics. The book concludes with a redefinition of ecological terms based on the physics of airflow and a summary of the theory and implications of olfactory predator-prey dynamics. Introducing the mechanics of olfaction and its influence on the behavior of both predators and prey Predator-Prey Dynamics: The Role of Olfaction presents a new perception of the world and enables us to understand and more effectively manage the delicate survival dynamics of animals in the wild. | Predator-Prey Dynamics The Role of Olfaction
