William Sanders - Böcker

This study, based on quantitative and qualitative data gathered over a twelve-year period, takes its title from the two predominant styles of gang violence: 'drive-bys,' which have replaced 'rumbles' as the primary form of gang violence; and 'gang-bangs' - a generic term for other gang violence that includes assaults, knifings, and beatings.The author attempts to understand the situations in which a young man would drive up to another human being and, without further ado, blow his head off. By examining hundreds of such situations, and employing both structural and phenomenological analysis, Sanders explores the various configurations of gang violence.Gangbangs and Drive-bys also examines the routines of gang members and their view of life, the different styles of gangs, and changes undergone by gangs from the early 1980s to the end of the same decade. Over that period, the emphasis shifted from parties and paybacks to big money from the sale of rock cocaine, and from unstructured to organized crime. Along with that shift came an increase in the violence.Finally, Sanders traces the beginning and evolution of a metropolitan police gang unit over the same decade in order to present an inside view of how the police attempt to deal with and understand gangs.

Build server-side applications more efficiently - and improve your PHP programming skills in the process - by learning how to use design patterns in your code. This book shows you how to apply several object-oriented patterns through simple examples, and demonstrates many of them in full-fledged working applications. Learn how these reusable patterns help you solve complex problems, organize object-oriented code, and revise a big project by only changing small parts. With Learning PHP Design Patterns, you'll learn how to adopt a more sophisticated programming style and dramatically reduce development time.Learn design pattern concepts, including how to select patterns to handle specific problems Get an overview of object-oriented programming concepts such as composition, encapsulation, polymorphism, and inheritance Apply creational design patterns to create pages dynamically, using a factory method instead of direct instantiation Make changes to existing objects or structure without having to change the original code, using structural design patterns Use behavioral patterns to help objects work together to perform tasks Interact with MySQL, using behavioral patterns such as Proxy and Chain of Responsibility Explore ways to use PHP's built-in design pattern interfaces
