Optimal patrol routes: interdicting and pursuing rhino poachers

Interdiction patrolling (also known as hot spots policing) is a proactive police operation that depends on good planning. And the pursuit of fleeing suspects is a challenging operation that all police forces engage in on a regular basis. We give software tools that improve the effectiveness of both. We demonstrate the effectiveness of our tools by applying them to the case of rhino poaching in wildlife reserves. An interdiction patrol pre-emptively seeks out poaching parties within a reserve. Upon picking up the trail of a poaching party, a pursuit team needs a pursuit strategy that optimizes their chances of an interception. Our interdiction patrol route tool identifies optimal interdiction patrol routes to walk. This tool is based on a Stackelberg game and represents different types of poachers and their utilities. These utilities are updated (learned) each time new information on poaching party routes is added to the database. Our second tool provides a real-time sequence of team member moves that maximizes the team’s chances of apprehending a pursued party. We show that our tools perform well when applied to simulated and real data.     

The rhetoric of personal loyalty to superiors in criminal justice agencies

Nowhere in public law is the idea of personal loyalty to superiors mentioned, yet criminal justice practitioners suffer from a “personal loyalty syndrome.” This syndrome holds them responsible to an altogether different set of loyalty expectations. They are often compelled to offer personal loyalty to unworthy superiors and, as a result, violate constitutional provisions, legal requirements, or the public good. While no organizational rules require any such loyalty, criminal justice practitioners are invariably taught that issues of loyalty at the workplace are so important that one cannot survive without personal loyalty to superiors. They are also reminded that violating such a “commandment” is a cardinal sin that can destroy one's career. This article discusses the arguments for and against personal loyalty to superiors and the dangers inherent in such relationships. It explains the grammar of loyalty at the workplace, explores the paradoxes of personal loyalty to superiors, and suggests a duty-based model as an alternative to the current model.     

HUMAN TISSUE LEGISLATION AND MEDICAL PRACTICE: A BENEFIT OR A BURDEN?

The scandals surrounding organ removal and retention throughout the United Kingdom provoked several Inquiries and ultimately led to law reform. Although the medical professions were well represented at the Inquiries, little was heard of the voices of those at the 'coal face'. In this scoping study, funded by the Wellcome Trust, we interviewed a number of doctors and others engaged in the uses of human tissue and organs to explore their hopes, concerns and fears about the role of the law in their practices. We found that those involved in transplantation were more aware of, and more actively involve with, the law, whereas others, such as pathologists, had less direct engagement with the law. Most of those we interviewed expressed the hope that law reform would provide much-needed clarity. Although some expressed concern that the law might be over-intrusive, most felt that the placing of authority firmly in the hands of the person him or her self to decide what should happen to their bodies was to be welcomed.     

Perils of the Deep: The Dangers of Submarine Proliferation in the Seas of East Asia

Abstract

Greater numbers of submarines are being acquired in the Asia-Pacific. This development poses challenges in the region for preventive diplomacy, maritime confidence building, and ensuring the safety of submarine operations. However, countries are extremely sensitive about submarine operations and meeting these challenges will be difficult. The article discusses technological developments with submarines and antisubmarine warfare and the implications for regional naval operations. It identifies the risks associated with increased numbers of submarines, particularly in the narrow seas of East Asia, and recommends measures that might mitigate the adverse consequences of submarine proliferation, including enhancing submarine safety. It concludes that there is a pressing need to start discussion of these measures in regional forums.     

“Global Jihad”: The Canadian Experience

This study aims to address the relative lack of research examining the Canadian experience of terrorism relating to the “Global Salafi Jihad.” The fundamental research question was “What have people living in, or from, Canada been doing to support or advance violent jihad either at home or abroad?” Data were collected on individuals active from the 1980s through to the end of 2011 in an effort to be as exhaustive as possible. They were analysed according to three broad categories: background variables; operational variables; and investigations and outcomes. The sample was further divided into two and results compared according to whether individuals began offending before or after September 11, 2001, in order to assess change over time. The article begins with a brief history of terrorism in Canada, followed by the methodology, analysis of variables, and summary and conclusions. Cases included and excluded from the analysis are listed in Appendices A and B respectively.
