An understanding of social policy is crucial for social workers as it underpins and shapes the legislative framework that they work within. From safeguarding service users and enabling them to improve their lives, to protecting the most vulnerable in society, social policy also has a vital role to play within social work education. It is therefore important that you, as a social work student, learn to engage critically with social policy. This book will introduce you to policy and show you how it has changed and evolved over time, how it reflects changes in society and how it can be applied to your practice.

Sociological perspectives can be used to analyse societal and structural influences on human behaviour at individual, group and community levels. The authors link sociological concepts, debates and theories relating to key areas such as poverty, social exclusion, education, social class and social justice to develop your students' understanding of how sociological perspectives will impact upon their social work placements and practice. This book begins by taking you step-by-step through the ins and outs of why sociology is important to social work. It explains the relevance of sociology to everyday social work practice, introducing you to the core sociological perspectives that you'll need to get to grips with during your course, including functionalism, Marxism, symbolic interactionism and postmodernism. The book then moves on to explore various social issues in detail (i.e. poverty, social class, social exclusion, education, moral panics), with extended case studies, activities and links to skills in practice illustrating the many opportunities and challenges that each aspect brings to everyday practice. There are also important chapters on family, community and the role of sociology in social work training.

Graphics Shaders: Theory and Practice is intended for a second course in computer graphics at the undergraduate or graduate level, introducing shader programming in general, but focusing on the GLSL shading language. While teaching how to write programmable shaders, the authors also teach and reinforce the fundamentals of computer graphics. The second edition has been updated to incorporate changes in the OpenGL API (OpenGL 4.x and GLSL 4.x0) and also has a chapter on the new tessellation shaders, including many practical examples. The book starts with a quick review of the graphics pipeline, emphasizing features that are rarely taught in introductory courses, but are immediately exposed in shader work. It then covers shader-specific theory for vertex, tessellation, geometry, and fragment shaders using the GLSL 4.x0 shading language. The text also introduces the freely available glman tool that enables you to develop, test, and tune shaders separately from the applications that will use them. The authors explore how shaders can be used to support a wide variety of applications and present examples of shaders in 3D geometry, scientific visualization, geometry morphing, algorithmic art, and more.Features of the Second Edition: Written using the most recent specification releases (OpenGL 4.x and GLSL 4.x0) including code examples brought up-to-date with the current standard of the GLSL language.More examples and more exercisesA chapter on tessellation shadersAn expanded Serious Fun chapter with examples that illustrate using shaders to produce fun effectsA discussion of how to handle the major changes occurring in the OpenGL standard, and some C++ classes to help you manage that transitionThe authors thoroughly explain the concepts, use sample code to describe details of the concepts, and then challenge you to extend the examples. They provide sample source code for many of the book’s examples at www.cgeducation.org

Introduced 160 years ago as an attempt to generalize complex numbers to higher dimensions, quaternions are now recognized as one of the most important concepts in modern computer graphics. They offer a powerful way to represent rotations and compared to rotation matrices they use less memory, compose faster, and are naturally suited for efficient interpolation of rotations. Despite this, many practitioners have avoided quaternions because of the mathematics used to understand them, hoping that some day a more intuitive description will be available.The wait is over. Andrew Hanson's new book is a fresh perspective on quaternions. The first part of the book focuses on visualizing quaternions to provide the intuition necessary to use them, and includes many illustrative examples to motivate why they are important—a beautiful introduction to those wanting to explore quaternions unencumbered by their mathematical aspects. The second part covers the all-important advanced applications, including quaternion curves, surfaces, and volumes. Finally, for those wanting the full story of the mathematics behind quaternions, there is a gentle introduction to their four-dimensional nature and to Clifford Algebras, the all-encompassing framework for vectors and quaternions.
