Forensic science is a growing presence in the classroom and this collection of 50 new experiments is an excellent resource; covers such topics as: visual identification, such as photos and image enhancement; personal identification, eg, DNA and fingerprints; chemical identification; biological, physical etc.
Introduces various aspects of forensic science--document examination, forgeries and counterfeiting, blood and DNA analysis, and trace evidence and provides suggestions for related projects.
Provides twenty experiments in forensic science that will intrigue both students and teachers and promote the interest in multiple science-process skills.
"Learn how to analyze soil, hair, and fibers; match glass and plastic specimens; develop latent fingerprints and reveal blood traces; conduct drug and toxicology tests; analyze gunshot and explosives residues; detect forgeries and fakes; analyze toolmark impressions and camera images; match pollen and diatom samples; extract, isolate, and visualize DNA samples"--P. [4] of cover.
This is the first text to examine the use of statistical methods in forensic science and bayesian statistics in combination. The book is split into two parts: Part One concentrates on the philosophies of statistical inference. Chapter One examines the differences between the frequentist, the likelihood and the Bayesian perspectives, before Chapter Two explores the Bayesian decision-theoretic perspective further, and looks at the benefits it carries. Part Two then introduces the reader to the practical aspects involved: the application, interpretation, summary and presentation of data analyses are all examined from a Bayesian decision-theoretic perspective. A wide range of statistical methods, essential in the analysis of forensic scientific data is explored. These include the comparison of allele proportions in populations, the comparison of means, the choice of sampling size, and the discrimination of items of evidence of unknown origin into predefined populations. Throughout this practical appraisal there are a wide variety of examples taken from the routine work of forensic scientists. These applications are demonstrated in the ever-more popular R language. The reader is taken through these applied examples in a step-by-step approach, discussing the methods at each stage.
The experiments in this volume are intended to mimic the types of investigations that would occur during a criminal forensics investigation.
With all of the new developments in information storage and retrieval, researchers today need a clear and comprehensive overview of the full range of their options, both online and offline, for finding the best information quickly. In this third edition of The Oxford Guide to Library Research, Thomas Mann maps out an array not just of important databases and print sources, but of several specific search techniques that can be applied profitably in any area of research. From academic resources to government documents to manuscripts in archives to business Web sites, Mann shows readers how best to exploit controlled subject headings, explains why browsing library shelves is still important in an online age, demonstrates how citation searching and related record searching produce results far beyond keyword inquiries, and offers practical tips on making personal contacts with knowledgeable people. Against the trendy but mistaken assumption that everything can be found on the Internet, Mann shows the lasting value of physical libraries and the unexpected power of traditional search mechanisms, while also providing the best overview of the new capabilities of computer indexing. Throughout the book Mann enlivens his advice with real-world examples derived from his experience of having helped thousands of researchers, with interests in all subjects areas, over a quarter century. Along the way he provides striking demonstrations and powerful arguments against those theorists who have mistakenly announced the demise of print. Essential reading for students, scholars, professional researchers, and laypersons, The Oxford Guide to Library Research offers a rich, inclusive overview of the information field, one that can save researchers countless hours of frustration in the search for the best sources on their topics.
This book highlights the contributions of leading forensic science practitioners, iconic figures who have been integral in both establishing current scientific and medicolegal practices and innovative evidence collection, testing, and analysis methods. Such professionals include Henry Lee, Michael Baden, William Bass, Jay Siegel, John Butler, Cyril Wecht, Vincent Di Maio, Marcella Fierro, Barry Fisher, and more. Previously unpublished interviews with these pioneers in the field, expressly undertaken for the purposes this book, examine the last 30 years—past trends that have shaped the field—as well as current and emerging trends that have, and will shape, the future of forensic science.
Ever wonder how forensics experts and law enforcement solve crimes? Learn how to build a crime lab of your very own with tools and supplies you can easily obtain. Then, following the step-by-step instructions, play the part of a forensic scientist by doing your own experiments, analyzing evidence and drawing conclusions.
