Needed at one moment, scorned at others, Mexican agricultural workers have moved back and forth across the US–Mexico border for the past century. In South Texas, Anglo growers’ dreams of creating a modern agricultural empire depended on continuous access to Mexican workers. While this access was officially regulated by immigration laws and policy promulgated in Washington, DC, in practice the migration of Mexican labor involved daily, on-the-ground negotiations among growers, workers, and the US Border Patrol. In a very real sense, these groups set the parameters of border enforcement policy. Managed Migrations examines the relationship between immigration laws and policy and the agricultural labor relations of growers and workers in South Texas and El Paso during the 1940s and 1950s. Cristina Salinas argues that immigration law was mainly enacted not in embassies or the halls of Congress but on the ground, as a result of daily decisions by the Border Patrol that growers and workers negotiated and contested. She describes how the INS devised techniques to facilitate high-volume yearly deportations and shows how the agency used these enforcement practices to manage the seasonal agricultural labor migration across the border. Her pioneering research reveals the great extent to which immigration policy was made at the local level, as well as the agency of Mexican farmworkers who managed to maintain their mobility and kinship networks despite the constraints of grower paternalism and enforcement actions by the Border Patrol.

Managing Systems Migrations and Upgrades is the perfect book for technology managers who want a rational guide to evaluating the business aspects of various possible technical solutions. Enterprises today are in the middle of the R&D race for technology leadership, with providers who increasingly need to create markets for new technologies while shortening development, implementation, and life cycles. The cost for the current tempo of technology life cycles is endless change-management controls, organizational chaos, production use of high-risk beta products, and greater potential for failure of existing systems during migration. Burkey and Breakfield help you answer questions such as, "Is the only solution open to me spending more that the industry average in order to succeed?" and "What are the warning signs that tell me to pass on a particular product offering?" as well as "How can my organization avoid the 'technical death marches' typical of the industry?" This book will take the confusion out of when to make shifts in your systems and help you evaluate the value proposition of these technology changes. · Provides a methodology for decision making and implementation of upgrades and migrations · Avoids marketing hype and the "technical herding" instinct · Offers a tool to optimize technology changes for both staff and customers

This book discusses regional and continental integration in Africa by examining the management of migration across the continent. It examines borders and securitisation of migration and the challenges and opportunities that arise out of reconfigured continental demographics. The book offers insights on intra-Africa migrations and highlights how intra-continental migration creates socio-economic and cultural borders. It explores how these borders, beyond the physical boundaries of states, including the Berlin Conference-constructed borders, create cultural divides, challenges for economic integration and cross-border security, and irregular migration patterns. While the movement of economic goods is valued for regional economic integration, the mobility of people is seen as a threat. This approach to migration contradicts the intentions of true integration and development, and triggers negative responses such as xenophobia that cannot be addressed by simply managing the physical border and allowing free movement. This book engages in a pivotal discussion of these issues, which are hitherto missing in African border studies, by demonstrating the ubiquity and overreaching influence of various kinds of borders on the African continent. With multidisciplinary contributions that provide an in-depth understanding of intra-Africa migrations and strategies for enhanced migration management, this book will be a useful resource for scholars and students studying geography, politics, security studies, development studies, African studies and sociology.

This new book, by the original developer of the BACnet standards, explains how BACnet's protocols manage all basic building functions in a seamless, integrated way. BACnet is a data communication protocol for building automation and control systems, developed within ASHRAE in cooperation with ANSI and the ISO. This book explains how BACnet works with all major control systems--including those made by Honeywell, Siemens, and Johnson Controls--to manage everything from heating to ventilation to lighting to fire control and alarm systems. BACnet is used today throughout the world for commercial and institutional buildings with complex mechanical and electrical systems. Contractors, architects, building systems engineers, and facilities managers must all be cognizant of BACnet and its applications. With a real 'seat at the table,' you'll find it easier to understand the intent and use of each of the data sharing techniques, controller requirements, and opportunities for interoperability between different manufacturers' controllers and systems. Highlights include: * A review of the history of BACnet and its essential features, including the object model, data links, network technologies, and BACnet system configurations; * Comprehensive coverage of services including object access, file access, remote device management, and BACnet-2012's new alarm and event capabilities; * Insight into future directions for BACnet, including wireless networking, network security, the use of IPv6, extensions for lifts and escalators, and a new set of BACnet Web Services; * Extensive reference appendices for all objects and services; and * Acronyms and abbreviations

The migrations of Wyoming's hooved mammals--mule deer, pronghorn, elk, and moose--between their seasonal ranges are some of the longest and most noteworthy migrations on the North American continent. Wild Migrations presents the previously untold story of these migrations, combining wildlife science and cartography. Facing pages cover more than 50 migration topics, ranging from ecology to conservation and management, enriched by visually stunning graphics and maps, and an introductory essay by Emilene Ostlind.
