Interpreting Policework - Policy and Practice in Forms of Beat Policing (Hardcover): Roger Grimshaw, Tony Jefferson Interpreting Policework - Policy and Practice in Forms of Beat Policing (Hardcover)

In the 1980s there existed wide and often acrimonious disagreement over the purposes and objectives of police organizations, the ways in which their activities were structured, and their relations with the wider society. Interpreting policework requires a rounded conception of policing, based on both a thorough critique of the main theoretical trends in police sociology, and close familiarity with actual patterns of policing, on the streets, in the stations, and inside the police headquarters where key policies are formulated. Originally published in 1987, the achievement of this book is that it combines rigorous theoretical analysis with a wealth of descriptive material drawn from first-hand observation of policing and decision making at all levels, and thus relates sociological theory to practice and political debate at the time. The introduction provides a careful analysis of central theoretical and political strands in police sociology, and proposes a new general conception of policework. The authors go on to provide vivid illustrations of this conception from the worlds of uniformed unit beat patrols and resident beat officers, and from the fora in which policy for operational practice is considered. A final section draws the wider lessons of these concrete analyses for sociological theory and for our understanding of past policy shifts from one form of beatwork to another, and spells out the radical implications of the study for the political debate on the future of policing. Interpreting Policework thus had relevance to students and researchers in police studies, sociology, public policy and the law at the time and will still be of historical interest today. The authors are experienced researchers, practised in investigating a wide range of criminological and social control issues.

Environmental Stratified Flows (Hardcover, 2002 ed.): Roger Grimshaw Environmental Stratified Flows (Hardcover, 2002 ed.)
Roger Grimshaw
R4,519 Discovery Miles 45 190 Ships in 10 - 15 working days

The dynamics of flows in density-stratified fluids has been and remains now an important topic for scientific enquiry. Such flows arise in many contexts, ranging from industrial settings to the oceanic and atmospheric environments. It is the latter topic which is the focus of this book. Both the ocean and atmosphere are characterised by the basic vertical density stratification, and this feature can affect the dynamics on all scales ranging from the micro-scale to the planetary scale. The aim of this book is to provide a "state-of-the-art" account of stratified flows as they are relevant to the ocean and atmosphere with a primary focus on meso-scale phenomena; that is, on phenomena whose time and space scales are such that the density stratification is a dominant effect, so that frictional and diffusive effects on the one hand and the effects of the earth's rotation on the other hand can be regarded as of less importance. This in turn leads to an emphasis on internal waves.

Nonlinear Waves in Fluids: Recent Advances and Modern Applications (Paperback, 2005 ed.): Roger Grimshaw Nonlinear Waves in Fluids: Recent Advances and Modern Applications (Paperback, 2005 ed.)

Although nonlinear waves occur in nearly all branches of physics and engi neering, there is an amazing degree of agreement about the fundamental con cepts and the basic paradigms. The underlying unity of the theory for linearized waves is already well-established, with the importance of such universal concepts as group velocity and wave superposition. For nonlinear waves the last few decades have seen the emergence of analogous unifying comcepts. The pervasiveness of the soliton concept is amply demonstrated by the ubiquity of such models as the Korteweg-de Vries equation and the nonlinear Schrodinger equation. Similarly, there is a universality in the study of wave-wave interactions, whether determin istic or statistical, and in the recent developments in the theory of wave-mean flow interactions. The aim of this text is to present the basic paradigms of weakly nonlinear waves in fluids. This book is the outcome of a CISM Summer School held at Udine from September 20-24, 2004. . Like the lectures given there the text covers asymptotic methods for the derivation of canonical evolution equations, such as the Kortew- de Vries and nonlinear Schrodinger equations, descriptions of the basic solution sets of these evolution equations, and the most relevant and compelling applica tions. These themes are interlocked, and this will be demonstrated throughout the text . The topics address any fluid flow application, but there is a bias towards geophysical fluid dynamics, reflecting for the most part the areas where many applications have been found."
