As well as an in-depth discussion of Random Controlled Trials (RCTs), this text highlights effective alternatives to this method and includes practical steps on how to successfully adopt them. Topics include:

·       The advantages of randomisation

·       How to avoid common design pitfalls that reduce the validity of experiments

·       How to maintain controlled settings and pilot tests ·       How to conduct quasi-experiments when RCTs are not an option

Practical and succintly written, this book will give you the know-how and confidence needed to succeed on your quantitative research journey.

At a time when resources are scarce, not every crime may be investigated as fully as is desirable. Police generally use experience to guide their case screening. This volume demonstrates a new, research-based approach, exploring innovative research on crime solvability as a factor for crime investigation and prevention.

Topics covered include:

Crime Solvability Factors: Police Resources and Crime Detection will be of interest to researchers in criminology and criminal justice, particularly with an interest in quantitative and experimental research and police studies. It will also be of interest to policymakers and police organizations.

This book explores the potential of domestic abuse data to assess the level of harm caused to victims and the amount of resources required to respond to it. Policing domestic abuse has become a major activity for the police service in England and Wales. Part of the police strategy is to gather hundreds of thousands of detailed records about victims and suspects – the single largest set of domestic abuse records available, but one that to date has largely unexplored by researchers. In this volume, Matthew Bland and Barak Ariel analyse three substantial datasets taken from police forces across the country and ask:

·         Can police data be used to derive meaningful insight?

·         How should we use these data to measure harm?

·         Just how much domestic abuse involves a repeat victim?

·         Does abuse get more serious over time?

·         Can serious domestic abuse be predicted before it occurs?

This volume illustrates the scale of the challenge the police and other agencies face with reducing domestic abuse. A small proportion of individuals generate a majority of harm; this book argues that police records offer opportunities to identify these individuals before the harm occurs. Demonstrating that statistical techniques can be used to profile domestic abuse to target harm reduction strategies more precisely and even identify a sizable proportion of serious cases before they occur, this volume will be of interest to law enforcement officials, policing researchers, and policy makers interested in reducing the phenomenon of domestic abuse.

This volume presents a collection of essays from experienced crime analysts from around the world. It explores themes relevant to anyone embarking on, or already into a career in crime analysis.

Divided into two sections, this book addresses technical issues central to the profession, from collection of data to presenting findings to reluctant audiences. It incorporates a collection of methodological case studies, demonstrating the ways analysis has made a meaningful difference to policing and security.

This brief investigates the usefulness of Body-worn videos (BWVs) in non-policing environments. The first study of this kind, this research presents new datasets related to these devices, including:

 TOCS’ data on assaults and injuries

•Surveys of frontline members of staff

•A series of focus groups

•BWV activation metadata from BWV vendors

•Surveys with British Transport Police’s criminal justice unit.

The data sources for this project span thirteen train operating companies across the UK, varying levels of risk of workplace violence, as well as different types of Public-Facing professionals and different BWV devices. Using a mixed-methods approach, this volume ultimately provides insight into the effectiveness of these devices in preventing and controlling risks of violence in the workplace, and recommendations on how to use them. This book is ideal for professionals working in workplace violence reduction and scholars who study technological advents, violence prevention and jurists who are interested in decisions to prosecute offenders. 

This book investigates the recent history of the drug market on the dark web and suggests interventions that can be used to curb the trade of illegal products in the internet''s underbelly. It outlines the current landscape of this market, highlighting:

• What is known about drug markets on the dark web.

• How transactions involving illicit goods occur in cryptomarkets.

• How the illegal trade of drugs is conducted in the dark web.

• The role of blockchain technology in these transactions.

The chapters that follow identify effective methods suppliers and purchasers employ to trade under conditions of uncertainty. They explore the role that trust plays in network structures and vendor selections for drug markets. The volume includes a review of the targeting strategies available for law enforcement and offers new solutions to target the trade of illicit goods on the dark web. It is ideal for law enforcement officers and practitioners combatting cybercrime.
