An "applications first" approach to discrete wavelet transformationsDiscrete Wavelet Transformations provides readers with a broad elementary... introduction to discrete wavelet transformations and their applications. With extensive graphical displays, this self-contained book integrates concepts from calculus and linear algebra into the construction of wavelet transformations and their various applications, including data compression, edge detection in images, and signal and image denoising.The book begins with a cursory look at wavelet transformation development and illustrates its allure in digital signal and image applications. Next, a chapter on digital image basics, quantitative and qualitative measures, and Huffman coding equips readers with the tools necessary to develop a comprehensive understanding of the applications. Subsequent chapters discuss the Fourier series, convolution, and filtering, as well as the Haar wavelet transform to introduce image compression and image edge detection. The development of Daubechies filtersis presented in addition to coverage of wavelet shrinkage in the area of image and signal denoising. The book concludes with the construction of biorthogonal filters and also describes their incorporation in the JPEG2000 image compression standard.The author's "applications first" approach promotes a hands-on treatment of wavelet transforma-tion construction, and over 400 exercises are presented in a multi-part format that guide readers through the solution to each problem. Over sixty computer labs and software development projects provide opportunities for readers to write modules and experiment with the ideas discussed throughout the text. The author's software package, DiscreteWavelets, is used to perform various imaging and audio tasks, compute wavelet transformations and inverses, and visualize the output of the computations. Supplementary material is also available via the book's related Web site, which includes an audio and video repository, final project modules, and softwarefor reproducing examples from the book. All software, including the DiscreteWavelets package, is available for use with Mathematica®, MATLAB®, and Maple.Discrete Wavelet Transformations strongly reinforces the use of mathematics in digital data applications, sharpens programming skills, and provides a foundation for further study of more advanced topics, such as real analysis. This book is ideal for courses on discrete wavelet transforms and their applications at the undergraduate level and also serves as an excellent reference for mathematicians, engineers, and scientists who wish to learn about discrete wavelet transforms at an elementary level.

These procedures, collectively known as discriminant analysis, allow a researcher to study the difference between two or more groups of objects with... respect to several variables simultaneously, determining whether meaningful differences exist between the groups and identifying the discriminating power of each variable.

Much as we “select” computer settings by default—reflexively, without thinking, and sometimes without realizing there are other options—we often... discriminate by default as well. And just as default computer settings tend to become locked in or entrenched as the standard, discrimination by default creates a situation in which disparate outcomes are expected, accepted, and taken for granted. The killing of Amadou Diallo, racial disparities in medical care, the dominance of Whites and men in certain professions, and even the uneven media attention paid to crimes depending on their victims’ race and class, all might be cases of discrimination by, or as, default.Wang contends that, today, most discrimination occurs by default and not design, making legal prohibitions that focus on those who discriminate out of ill will inadequate to redress the largest share of modern discrimination. She draws on social psychology to detail three ways in which unconscious assumptions can lead to discrimination, showing how they play out in a range of everyday settings. Wang then demonstrates how these dynamics interact in medical care to produce an invisible, self-fulfilling, and self-perpetuating prophecy of racial disparity. She goes on to suggest ways in which institutions and individuals might recognize, interrupt, and override the discriminatory default.

Discrimination by Design is a fascinating account of the complex social processes and power struggles involved in building and controlling space. Leslie... Kanes Weisman offers a new framework for understanding the spatial dimensions of gender and race as well as class. She traces the social and architectural histories of the skyscraper, maternity hospital, department store, shopping mall, nuclear family dream house, and public housing high rise. Her vivid prose is based on exhaustive research and documents how each setting, along with public parks and streets, embodies and transmits the privileges and penalties of social caste. In presenting feminist themes from a spatial perspective, Weisman raises many new and important questions. When do women feel unsafe in cities, and why? Why do so many homeless people prefer to sleep on the streets rather than in city-run shelters? Why does the current housing crisis pose a greater threat to women than to men? How would dwellings, communities, and public buildings look if they were designed to foster relationships of equality and environmental wholeness? And how can we begin to imagine such a radically different landscape? In exploring the answers, the author introduces us to the people, policies, architectural innovations, and ideologies working today to shape a future in which all people matter. Richly illustrated with photographs and drawings, Discrimination by Design is an invaluable and pioneering contribution to our understanding of the issues of our time--health care for the elderly and people with AIDS, homelessness, racial justice, changing conditions of work and family life, affordable housing, militarism, energy conservation, and thepreservation of the environment. This thoroughly readable book provides practical guidance to policymakers, architects, planners, and housing activists. It should be read by all who are interested in understanding how the built environment shapes the experiences of their daily lives

Paru en 1755, le Discours sur l'origine et les fondements de l'inégalité parmi les hommes peut être considéré comme la matrice de l'œuvre morale... et politique de Rousseau : il y affirme sa stature de philosophe, l'originalité de sa voix, la force de son « système ». Résoudre le problème posé par l'Académie de Dijon - » quelle est la source de l'inégalité parmi les hommes et si elle est autorisée par la loi naturelle ? » -, en d'autres termes expliquer que riches et puissants dominent leurs semblables sur lesquels ils n'ont pas de réelle supériorité, exige aux yeux de Rousseau de poser à nouveaux frais la question « qu'est-ce que l'homme ? ». Pour cela, il faut comprendre comment s'est formée sa « nature actuelle », si éloignée de ce que serait son état de nature : « Si je me suis étendu si longtemps sur la supposition de cette condition primitive, c'est qu'ayant d'anciennes erreurs et des préjugés invétérés à détruire, j'ai cru devoir creuser jusqu'à la racine... ».

In this book, John Dryzek criticizes the dominance of instrumental rationality and objectivism in political institutions and public policy and in the... practice of political science. He argues that the reliance on these kinds of politics and to technocracies of expert cultures that are not only repressive, but surprisingly ill-equipped for dealing with complex social problems. Drawing on critical theory, he outlines an alternative program for the organization of political institutions advocating a form of communicatively rational democracy, which he terms discursive democracy, that stresses the importance of active citizenship and public discourse. He draws out the limitations of instrumental rationality and investigates how policy analysis and political science may be reformed to help constitute and comprehend democracy. Discursive Democracy examines how the political process can be made more vital and meaningful. At the same time it shows how such an invigorated process will serve as a more effective agent for social problem solving.

Discursive Leadership: In Conversation with Leadership Psychology presents a new, groundbreaking way for scholars and graduate students to examine and... explore leadership. Differing from a psychological approach to leadership which tries to get inside the heads of leaders and employees, author Gail Fairhurst focuses on the social or communicative aspects between them. A discursive approach to leadership introduces a host of relatively new ideas and concepts and helps us understand leadership’s changing role in organizations.
