Sommario/riassunto

Differential-algebraic equations (DAEs) provide an essential tool for system modeling and analysis within different fields of applied sciences and engineering. This book addresses modeling issues and analytical properties of DAEs, together with some applications in electrical circuit theory.Beginning with elementary aspects, the author succeeds in providing a self-contained and comprehensive presentation of several advanced topics in DAE theory, such as the full characterization of linear time-varying equations via projector methods or the geometric reduction of nonlinear systems.

Sommario/riassunto

To understand border enforcement and the shape it has taken, it is imperative to examine a groundbreaking Border Patrol operation begun in 1993 in El Paso, Texas, "Operation Blockade." The El Paso Border Patrol designed and implemented this radical new strategy, posting 400 agents directly on the banks of the Rio Grande in highly visible positions to deter unauthorized border crossings into the urban areas of El Paso from neighboring Ciudad Juárez—a marked departure from the traditional strategy of apprehending unauthorized crossers after entry. This approach, of "prevention through deterrence," became the foundation of the 1994 and 2004 National Border Patrol Strategies for the Southern Border. Politically popular overall, it has rendered unauthorized border crossing far less visible in many key urban areas. However, the real effectiveness of the strategy is debatable, at best. Its



implementation has also led to a sharp rise in the number of deaths of unauthorized border crossers. Here, Dunn examines the paradigm-changing Operation Blockade and related border enforcement efforts in the El Paso region in great detail, as well as the local social and political situation that spawned the approach and has shaped it since. Dunn particularly spotlights the human rights abuses and enforcement excesses inflicted on local Mexican Americans and Mexican immigrants as well as the challenges to those abuses. Throughout the book, Dunn filters his research and fieldwork through two competing lenses, human rights versus the rights of national sovereignty and citizenship.

Sommario/riassunto

"This edited book examines current methods for the statistical analysis of hypotheses that are compatible with direction dependence. The proposed book is divided in four parts, each consisting of two or more chapters, for a total of 14 chapters. The first part of this book introduces the fundamental concepts of direction dependence in statistical models. The authors provide a historical view on the origins of studying the direction of dependence in a regression line. Various classes of copulas with directional dependence properties are introduced. In addition, an introduction into copula regression functions and concomitants of order statistics in directional dependence modeling is given. Part II of the proposed book is devoted to recent developments and advances in direction dependence modeling of continuous variables and contains six chapters. The author demonstrates the benefits of incorporating concepts of direction dependence to identify causal models. Part III of the proposed volume introduces direction dependence methods for the categorical variable case. Finally, Part IV of the proposed book is devoted to substantive theory and real-world applications and consists of four chapters. The author introduces custom dialogs and macros in SPSS to make direction dependence analysis accessible to applied empirical researchers."--
