This book analyses the arrival of emerging and traditional information and technology for public and economic use in Latin America. It focuses on the governmental, economic and security issues and the study of the complex relationship between citizens and government. The book is divided into three parts: * 'Digital data and privacy, prospects and barriers' centers on the debates among the right of privacy and the loss of intimacy in the Internet, * 'Homeland security and human rights' focuses on how novel technologies such as drones and autonomous weapons systems reconfigure the strategies of police authorities and organized crime, * 'Labor Markets, digital media and emerging technologies' emphasize the legal, economic and social perils and challenges caused by the increased presence of social media, blockchain-based applications, artificial intelligence and automation technologies in the Latin American economy. This first volume in a two volume set will be important reading for scholars and students of governance in Latin American, the protection of human rights and the use of technology to combat crime and the new advances of digital economy in the region.

Environmental sustainability issues in a fragile, semi-arid region and its coastal area, which experience climate changes from extreme drought conditions to the effects of hurricanes over a period of weeks to years, provide specific challenges for the ecosystems and the populations existing within the region. The research presented focuses on the problems and some solutions specific to the South Texas-Mexico border region, on both sides of the Rio Grande, focusing on water and air pollution. "

This book organizes principles and methods of signal processing and machine learning into the framework of coherence. The book contains a wealth of classical and modern methods of inference, some reported here for the first time. General results are applied to problems in communications, cognitive radio, passive and active radar and sonar, multi-sensor array processing, spectrum analysis, hyperspectral imaging, subspace clustering, and related. The reader will find new results for model fitting; for dimension reduction in models and ambient spaces; for detection, estimation, and space-time series analysis; for subspace averaging; and for uncertainty quantification. Throughout, the transformation invariances of statistics are clarified, geometries are illuminated, and null distributions are given where tractable. Stochastic representations are emphasized, as these are central to Monte Carlo simulations. The appendices contain a comprehensive account of matrix theory, the SVD, the multivariate normal distribution, and many of the important distributions for coherence statistics. The book begins with a review of classical results in the physical and engineering sciences where coherence plays a fundamental role. Then least squares theory and the theory of minimum mean-squared error estimation are developed, with special attention paid to statistics that may be interpreted as coherence statistics. A chapter on classical hypothesis tests for covariance structure introduces the next three chapters on matched and adaptive subspace detectors. These detectors are derived from likelihood reasoning, but it is their geometries and invariances that qualify them as coherence statistics. A chapter on independence testing in space-time data sets leads to a definition of broadband coherence, and contains novel applications to cognitive radio and the analysis of cyclostationarity. The chapter on subspace averaging reviews basic results and derives an order-fitting rule for determining the dimension of an average subspace. These results are used to enumerate sources of acoustic and electromagnetic radiation and to cluster subspaces into similarity classes. The chapter on performance bounds and uncertainty quantification emphasizes the geometry of the Cramer-Rao bound and its related information geometry.

This volume focuses on the hyper-mediatization of Latin America from the citizen's perspective, considering the social impact and how people embrace information technologies to improve their living conditions, engage in political issues and the role of digital journalism in promoting democratic values in Latin America. The book is divided into three parts: 'Digital Media and Daily Life in Latin America' explores cases related to the integration of digital media such as mobile devices, social platforms and, even, drones to diverse commercial, private and social activities. 'Information technologies and civic engagement' gives special attention to the new political practices triggered by the irruption of smartphones and platforms, especially inside organizations and social movements in Latin America. 'Journalism and Media Integrity in the Age of Post-truth' centers on the study of digital journalism and the new media landscape, and related issues like precarization of labor conditions and the crisis of reliability in media. This second volume in a two volume set will be important reading for scholars and students of social use of digital media in Latin America, civic engagement, and the connections between politics, journalism and technology.
