"Despite dramatic social transformations in the United States during the last 150 years, the South has remained staunchly conservative. Southerners are more likely to support Republican candidates, gun rights, and the death penalty, and southern whites harbor higher levels of racial resentment than whites in other parts of the country. Why haven't these sentiments evolved or changed? Deep Roots shows that the entrenched political and racial views of contemporary white southerners are a direct consequence of the region's slaveholding history, which continues to shape economic, political, and social spheres. Today, southern whites who live in areas once reliant on slavery--compared to areas that were not--are more racially hostile and less amenable to policies that could promote black progress. Highlighting the connection between historical institutions and contemporary political attitudes, the authors explore the period following the Civil War when elite whites in former bastions of slavery had political and economic incentives to encourage the development of anti-black laws and practices. Deep Roots shows that these forces created a local political culture steeped in racial prejudice, and that these viewpoints have been passed down over generations, from parents to children and via communities, through a process called behavioral path dependence. While legislation such as the Civil Rights Act and the Voting Rights Act made huge strides in increasing economic opportunity and reducing educational disparities, southern slavery has had a profound, lasting, and self-reinforcing influence on regional and national politics that can still be felt today. A groundbreaking look at the ways institutions of the past continue to sway attitudes of the present, Deep Roots demonstrates how social beliefs persist long after the formal policies that created those beliefs have been eradicated."--Jacket.

Do information and communication technologies networks really lead to a weakening of the nation-state? This volume revisits the 'retreat of the state' thesis and tests its validity in the 21st century. It will intrigue the reader with expert-level analysis, providing historical context and conceptualizing trends and social dynamics.

Master the concepts and techniques that will help you gain the LX0-103 and LX0-104 certifications on your first attempt Key FeaturesGet a clear understanding of how to achieve the Linux+ certificationExplore system architecture, shell scripts, data management, and Linux securityWork through practice and mock tests to pass both LX0-103 and LX0-104 examsBook Description Linux+ certification demonstrates technical competency and provides a broad awareness of Linux operating systems. Professionals who have achieved the Linux+ certification exhibit all-important knowledge of installation, operation, administration, and troubleshooting services. The CompTIA Linux+ Certification Guide is an overview of the certification that gives you insights into the system architecture. You’ll understand how to install and uninstall Linux distributions, followed by working with various package managers. Once you’ve grasped all this, you’ll move on to manipulating files and processes at command-line interface (CLI) and creating, monitoring, killing, restarting, and modifying processes. As you progress, you’ll be equipped to work with display managers and learn how to create, modify, and remove user accounts and groups, as well as understand how to automate tasks. The last set of chapters helps you configure dates and set up local and remote system logging. In addition to this, you’ll explore different internet protocols, along with discovering network configuration, security administration, Shell scripting, and SQL management. By the end of this book, you’ll not only have got to grips with all the modules using practice questions and mock exams, but you’ll also be well prepared to pass the LX0-103 and LX0-104 certification exams.

This guide is also for system administrators and rookie Linux professionals interested in enhancing their Linux and Shell scripting skills. No prior knowledge of Linux is needed, although some understanding of Shell scripting would be helpful.

Cloud Computing: Concepts, Technology, Security & Architecture Cloud computing has become an integral and foundational part of information technology. The majority of digital business activity and technology innovation occurs with the involvement of contemporary cloud environments that provide highly sophisticated automated technology infrastructure and a vast range of technology resources. To successfully build upon, interact with, or create a cloud environment requires an understanding of its common inner mechanics, architectural layers, models, and security controls. It also requires an understanding of the business and economic factors that justify the adoption and real-world use of clouds and cloud-based products and services. In Cloud Computing: Concepts, Technology, Security & Architecture, Thomas Erl, one of the world's top-selling IT authors, teams up with cloud computing expert Eric Barceló Monroy and researchers to break down proven and mature cloud computing technologies and practices into a series of well-defined concepts, technology mechanisms, and technology architectures. Comprehensive coverage of containerization and cybersecurity topics is also included. All chapters are carefully authored from an industry-centric and vendor-neutral point of view. In doing so, the book establishes concrete, academic coverage with a focus on structure, clarity, and well-defined building blocks for mainstream cloud computing and containerization platforms and solutions. With nearly 370 figures, 40 architectural models, and 50 mechanisms, this indispensable guide provides a comprehensive education of contemporary cloud computing, containerization, and cybersecurity that will never leave your side.

This volume contains 16 carefully refereed articles by participants in the Special Semester and the AMS Special Session on Real Algebraic Geometry and Ordered Structures held at Louisiana State University and Southern University (Baton Rouge). The 23 contributors to this volume were among the 75 mathematicians from 15 countries who participated in the special semester. Topics include the topology of real algebraic curves (Hilbert's 16th problem), moduli of real algebraic curves, effective sums of squares of real forms (Hilbert's 17th problem), efficient real quantifier elimination, subanalytic sets and stratifications, semialgebraic singularity theory, radial vector fields, exponential functions and valuations on nonarchimedean ordered fields, valued field extensions, partially ordered and lattice-ordered rings, rings of continuous functions, spectra of rings, and abstract spaces of (higher-level) orderings and real places. This volume provides a good overview of the state of the art in this area in the 1990s. It includes both expository and original research papers by top workers in this thriving field. The authors and editors strived to make the volume useful to a wide audience (including students and researchers) interested in real algebraic geometry and ordered structures-two subjects that are obviously related, but seldom brought together.
