1. Cutting-edge synthesis of key areas in substance use and misuse, which sets it apart from competing biopsychology textbooks 2. Each chapter is written by leading experts on the topic in question, recruited from research teams around the world (including UK, US, Europe, New Zealand, Canada, Asia), who have a detailed knowledge of the relevant literature. 3. Important methodological and ethical issues are explored, with reference to various cultural contexts.

Dark networks are the illegal and covert networks (e.g, insurgents, jihadi groups, or drug cartels) that security and intelligence analysts must track and identify to be able to disrupt and dismantle them. This text explains how this can be done by using the Social Network Analysis (SNA) method. Written in an accessible manner, it provides an introduction to SNA, presenting tools and concepts, and showing how SNA can inform the crafting of a wide array of strategies for the tracking and disrupting of dark networks.

This book explores the relationship between Conservative party politics and British colonial policy in tropical Africa during the unbroken period of Conservative government from 1951 to 1964. Based particularly on recently released documentary evidence, much of it never before published, Philip Murphy's study traces the development of Conservative attitudes towards Britain's role as a colonial power and describes reactions within the party to the rapid British withdrawal from Africa following the 1959 General Election. Making a clear distinction between the Conservative party and the machinery of government over which Conservative ministers presided, Dr Murphy examines how the party itself exercised a direct influence over the struggle for power between competing interest groups within the African colonies. He assesses the links between the Conservatives and the so-called 'multi-racial' parties, intended by Britain to play an important part in political development in Africa, and the ties between Conservative politicians and British businessmen active in the continent. Dr Murphy's analysis makes an important contribution to the debate on the process of decolonization, highlighting the variety of ways in which metropolitan party politics could influence the transfer of power.

This unique and meticulously-researched study examines the triangular relationship between the British government, the Palace, and the modern Commonwealth since 1945. It has two principal areas of focus: the monarch's role as sovereign of a series of Commonwealth Realms, and quite separately as head of the Commonwealth. It traces how, in the early part of the twentieth century, the British government promoted the Crown as a counterbalance to the centrifugal forces that were drawing the Empire apart. Ultimately, however, with newly-independent India's determination to become a republic in the late 1940s, Britain had to accept that allegiance to the Crown could no longer be the common factor binding the Commonwealth together. It therefore devised the notion of the headship of the Commonwealth as a means of enabling a republican India 'to continue to give the monarchy a pivotal symbolic role and therefore to remain in the Commonwealth.' In the years of rapid decolonization which followed 1945, it became clear that this elaborate constitutional infrastructure posed significant problems for British foreign policy. The system of Commonwealth Realms was a recipe for confusion and misunderstanding. Policy makers in the UK increasingly saw it as a liability in terms of Britain's relations with its former colonies, so much so that by the early 1960s they actively sought to persuade African nationalist leaders to adopt republican constitutions on independence. The headship of the Commonwealth also became a cause for concern, partly because it offered opportunities for the monarch to act without ministerial advice, and partly because it tended to tie the British government to what many within the UK had begun to regard as a largely redundant institution. Philip Murphy employs a large amount of previously-unpublished documentary evidence to argue that the monarchy's relationship with the Commonwealth, which was initially promoted by the UK as a means of strengthening Imperial ties, increasingly became an source of frustration for British foreign policy makers.

In the wake of Brexit, the Commonwealth has been identified as an important body for future British trade and diplomacy, but few know what it actually does. How is it organised and what has held it together for so long? How important is the Queen's role as Head of the Commonwealth? Most importantly, why has it had such a troubled recent past, and is it realistic to imagine that its fortunes might be reversed? In The Empire's New Clothes, Murphy strips away the gilded self-image of the Commonwealth to reveal an irrelevant institution afflicted by imperial amnesia. He offers a personal perspective on this complex and poorly understood institution, and asks if it can ever escape from the shadow of the British Empire to become an organisation based on shared values, rather than a shared history.

By the early twentieth century it was becoming clear that the Empire was falling apart. The British government promoted the Crown as a counterbalance to the forces drawing the Empire apart, but when India declared their intent to become a republic in the late 1940s, Britain had to accept that allegiance to the Crown could no longer be the common factor binding the Commonwealth together. They devised the notion of the Headship of the Commonwealth, enabling India to remain in the Commonwealth while continuing to give the monarchy a pivotal symbolic role. Monarchy and the End of Empire provides a unique insight on the triangular relationship between the British government, the Palace, and the modern Commonwealth since 1945. In the years of rapid decolonization which followed 1945 it became clear that this elaborate constitutional infrastructure posed significant problems for British foreign policy. Not only did it offer opportunities for the monarch to act without ministerial advice, it also tied the British government to what many within the UK had begun to regard as a largely redundant institution. Philip Murphy employs a large amount of previously-unpublished documentary evidence to argue that the monarchy's relationship with the Commonwealth, initially promoted by the UK as a means of strengthening Imperial ties, had increasingly become an impediment to British foreign policy.
