This book is a timely review of scholarship in social work supervision; re-examining the state of knowledge, research and practice; and asking if it is time for a new paradigm for the field.The contributors present a universal paradigm in social work around what we understand social work to be, not only through its practice of supervision but also what this contributes to the challenge of any dominant ideas or ideals about the supervision agenda in an increasingly globalised social work context. Capturing new developments from different regions of the world, the book shows how these can inform critical practice, professional development and well-being, and have a wider impact on accountability, effectiveness and work performance.The book will be appreciated by people needing or using services, novice or learner social workers, and those responsible for training or educating in supervision knowledge and skills or preparing to take up this important role. With applications for both academic research and practitioner-based learning, this book will help to ensure the best quality and supportive practice within the workforce and community it serves. This book was originally published as a special issue of the European Journal of Social Work.

It also sets the agenda for the future development of social work supervision internationally. Social work supervision is examined across countries, practice settings, and in terms of participants' roles, relationships, and responsibilities. Contributors show how and why social work supervision is integral to social work and the rich diversity of ways supervision can be practiced. Bringing together an international team of social work supervision scholars, researchers, supervisors, and practitioners, this handbook is essential reading for social workers, supervisors, managers, policy advisors, and professional leaders.

Merchants of death was an epithet used in the USA in the 1930s to attack industries and banks that supplied and funded the First World War (then called the Great War). The term was popular in anti-war circles of both the left and the right and was used extensively regarding the Senate hearings in 1936 by the Nye Committee. Originally published in 1934, this book uses the term to expose the international arms industry at the time. It is a careful and subtle, but still passionate, attack on those who would use government to profit themselves at the expense of other people's lives and property. The book not only makes the case against the war machine; it provides a scintillating history of war profiteering, one authoritative enough for citation and academic study.

The general idea advocated in this work is to start from complicated mathematical models describing wave motion as it results from the rules of continuum mechanics, and then to find a simpler viewpoint that still keeps everything essential preserved. Special attention is paid to the description of the sources of nonlinearities. The complexities in modelling are demonstrated by several examples including solitons, propagating instabilities and waves in waveguides. The selected case studies show some unconventional approaches in order to explain the richness of nonlinear wave motion. The final chapters are of more general character, including the essays on nonlinearity, beauty, and complexity. In this way, the thread of the analysis is the following: simple basic arguments result in a complicated theory that, in turn, needs certain simplifications in order to grasp the physical phenomena involved. What makes this book special compared to other books in the field is that all the examples are cast into a general philosophical network of complexity and simplicity.
