Covers new trace evidence techniques and expanding areas of analysis, along with key theory and applications Developed around the need for updated information in the disciplines of trace evidence the Handbook of Trace Evidence Analysis focuses on the increasing awareness and need for validation, modern methods for addressing and controlling contamination, the shift towards incorporating statistical analyses into the interpretation phase and cutting edge research into new forensic science methods and their application. Beginning with an overview of the topic and discussing the important role that information derived from trace materials can provide during investigations, the book then presents chapters on key techniques. The first being the critical nature of microscopy, and the methods employed for the recognition, collection, and preservation of trace evidence. Subsequent chapters review the core disciplines of trace evidence examination: paints and polymers, hairs, fibers and textiles and glass. Each chapter contains in-depth discussions on the origin of the materials involved, including any natural or synthetic processes involved in their production, the nuances involved in their detection, and the methods of analysis that are used to extract valuable information from samples. In addition, suggested workflows in method and testing selections, as well as addressing specific scientific challenges as well as the limitations of knowledge on the transfer, persistence and background abundance of trace materials are discussed. The book ends by examining the interpretation of trace evidence findings from a historical perspective and examining the methods that are currently being developed. Provides an in-depth introduction to the general area of trace evidence and discusses current and new techniques Consolidates trace evidence and materials categories of testing into one reference series Offers a detailed focus on technical approaches and guidelines to trace evidence Includes analytical schemes/workflows and valuable guides for the interpretation of data and results The Handbook of Trace Evidence will appeal to forensic science academics, students, and practitioners in the trace evidence and materials science disciplines, as well as DNA analysts, toxicologists, forensic anthropologists, crime laboratory managers, criminal justice students and practitioners, and legal professionals. It would also be a valuable resource for every crime laboratory reference library.

The successful 30-Second series tackles numbers, with experts on maths and data demystifying the essential numerical topics. We know that we use numbers pretty often, some of us confidently, others reluctantly. But are we aware of just how essential they are to almost every decision we make? Counting and measuring when we're shopping, travelling, studying or playing are just the beginning; the applications of numbers are endless, from assessing variables and analysing data to the calculations and predictions of advanced artificial intelligence. 30-Second Numbers explores number categories, the science of measuring, how guesstimates work, and the visualisation of numbers, taking you behind the digits into the world of statistics, probability, risk and ratios. Numbers are our way of imposing order on the world, and each of the 50 topics here uses just 300 words and one picture to give you a sense of control, helping you to understand trends in statistical data, how algorithms are used and the methods involved in machine learning. With this book, numbers need never be daunting again.

Humanity's most appalling crimes are solved by experts presenting painstakingly gathered evidence to the court of law. Investigators rely on physical, chemical and digital clues gathered at the scene of an incident to reconstruct beyond all reasonable doubt the events that occurred in order to bring criminals to justice. Enter the forensic team, tasked with providing objective recognition and identification and evaluating physical evidence (the clues) to support known or suspected circumstances. Far from the super-sleuths of fiction, the real-life masters of deduction occupy a world of dogged detection, analysing fingerprints or gait, identifying traces of toxins, drugs or explosives, matching digital data, performing anatomical dissection, disease diagnosis, facial reconstruction and environmental profiling.
