Book Description
A valuable new edition of a standard reference The use of statistical methods for categorical data has increased dramatically, particularly for applications in the biomedical and social sciences. An Introduction to Categorical Data Analysis, Third Edition summarizes these methods and shows readers how to use them using software. Readers will find a unified generalized linear models approach that connects logistic regression and loglinear models for discrete data with normal regression for continuous data. Adding to the value in the new edition is: • Illustrations of the use of R software to perform all the analyses in the book • A new chapter on alternative methods for categorical data, including smoothing and regularization methods (such as the lasso), classification methods such as linear discriminant analysis and classification trees, and cluster analysis • New sections in many chapters introducing the Bayesian approach for the methods of that chapter • More than 70 analyses of data sets to illustrate application of the methods, and about 200 exercises, many containing other data sets • An appendix showing how to use SAS, Stata, and SPSS, and an appendix with short solutions to most odd-numbered exercises Written in an applied, nontechnical style, this book illustrates the methods using a wide variety of real data, including medical clinical trials, environmental questions, drug use by teenagers, horseshoe crab mating, basketball shooting, correlates of happiness, and much more. An Introduction to Categorical Data Analysis, Third Edition is an invaluable tool for statisticians and biostatisticians as well as methodologists in the social and behavioral sciences, medicine and public health, marketing, education, and the biological and agricultural sciences.

Book Description
Networks of Outrage and Hope is an exploration of the new forms of social movements and protests that are erupting in the world today, from the Arab uprisings to the indignadas movement in Spain, from the Occupy Wall Street movement to the social protests in Turkey, Brazil and elsewhere. While these and similar social movements differ in many important ways, there is one thing they share in common: they are all interwoven inextricably with the creation of autonomous communication networks supported by the Internet and wireless communication. In this new edition of his timely and important book, Manuel Castells examines the social, cultural and political roots of these new social movements, studies their innovative forms of self-organization, assesses the precise role of technology in the dynamics of the movements, suggests the reasons for the support they have found in large segments of society, and probes their capacity to induce political change by influencing people’s minds. Two new chapters bring the analysis up-to-date and draw out the implications of these social movements and protests for understanding the new forms of social change and political democracy in the global network society.

Book Description
A historical study of Chile's twin experiments with cybernetics and socialism, and what they tell us about the relationship of technology and politics. In Cybernetic Revolutionaries, Eden Medina tells the history of two intersecting utopian visions, one political and one technological. The first was Chile's experiment with peaceful socialist change under Salvador Allende; the second was the simultaneous attempt to build a computer system that would manage Chile's economy. Neither vision was fully realized—Allende's government ended with a violent military coup; the system, known as Project Cybersyn, was never completely implemented—but they hold lessons for today about the relationship between technology and politics. Drawing on extensive archival material and interviews, Medina examines the cybernetic system envisioned by the Chilean government—which was to feature holistic system design, decentralized management, human-computer interaction, a national telex network, near real-time control of the growing industrial sector, and modeling the behavior of dynamic systems. She also describes, and documents with photographs, the network's Star Trek-like operations room, which featured swivel chairs with armrest control panels, a wall of screens displaying data, and flashing red lights to indicate economic emergencies. Studying project Cybersyn today helps us understand not only the technological ambitions of a government in the midst of political change but also the limitations of the Chilean revolution. This history further shows how human attempts to combine the political and the technological with the goal of creating a more just society can open new technological, intellectual, and political possibilities. Technologies, Medina writes, are historical texts; when we read them we are reading history.

Book Description
In Paper Cadavers, an inside account of the astonishing discovery and rescue of Guatemala's secret police archives, Kirsten Weld probes the politics of memory, the wages of the Cold War, and the stakes of historical knowledge production. After Guatemala's bloody thirty-six years of civil war (1960–1996), silence and impunity reigned. That is, until 2005, when human rights investigators stumbled on the archives of the country's National Police, which, at 75 million pages, proved to be the largest trove of secret state records ever found in Latin America. The unearthing of the archives renewed fierce debates about history, memory, and justice. In Paper Cadavers, Weld explores Guatemala's struggles to manage this avalanche of evidence of past war crimes, providing a firsthand look at how postwar justice activists worked to reconfigure terror archives into implements of social change. Tracing the history of the police files as they were transformed from weapons of counterinsurgency into tools for post-conflict reckoning, Weld sheds light on the country's fraught transition from war to an uneasy peace, reflecting on how societies forget and remember political violence.

Book Description
In recent times what has become known as "the case of Medellín " has generated a growing interest in the international community. These urban transformation that Medellín has experimented have become a focus of attention and reference for experts in many fields, around the world. The book ́Medellin: Environment, Urbanism and Society ́, that now published the Center for Urban and Environmental Studies, Urbam, of EAFIT University is a testimony of the value given by our culture to the accomplishments of the city, to the idea of the public sphere and the growing relationship between the technical sphere and the political sphere, understood in the broad sense as a form of disciplinary knowledge and construction of civil society. This book brings together a knowledge of the city from multiple perspectives; knowledge that is, without any doubt, impressive for its extension and profoundity, as well as for its capacity to combine objective data with conceptual reflections about the scope and impact of the different perspectives concerning the theme of urban transformation and the different actors that have participated in such processes. The book weaves a broad net over the city, its history and development, adopting a multidisciplinary vision. I think that this will be the first step in creating a speech that might finally liberate itself from the strict disciplinary boundaries, building a trans-disciplinary perspective that can amplify the urban dimension of the city. This is the beginning of a profound and complex reflection that is, at the same time, a project of knowledge and an instrument of action and participation.

Book Description
"Since the Mexican government escalated its war on organized crime at the end of 2006, over 150,000 Mexicans have been intentionally murdered. Countless thousands of others have been tortured; no one knows how many have disappeared. Caught between government forces and organized crime cartels, the Mexican people have suffered as atrocities and impunity reign. Based on three years of research, over 100 interviews, and previously unreleased government documents, this report finds a reasonable basis to believe that government forces and members of criminal cartels have perpetrated crimes against humanity in Mexico. The report comprehensively examines why there has been so little justice for atrocity crimes, and finds the main answers in political obstruction. Given the lack of political will to end impunity, new approaches must be taken. The report argues for a series of institutional changes, most importantly the creation of an internationalized investigative body, based inside Mexico, with powers to independently investigate and prosecute atrocity crimes."--Page 4 of cover.
