Homelessness has become a lasting issue of vital social concern. As the number of the homeless has grown, the complexity of the issue has become increasingly clear to researchers and private and public service providers. The plight of the homeless raises many ethical, anthropological, political, sociological, and public health questions. The most serious and perplexing of these questions is what steps private, charitable, and public organizations can take to alleviate and eventually solve the problem. The concept of homelessness is difficult to define and measure. Generally, persons are thought to be homeless if they have no permanent residence and seek security, rest, and protection from the elements. The homeless typically live in areas that are not designed to be shelters (e.g., parks, bus terminals, under bridges, in cars), occupy structures without permission (e.g., squatters), or are provided emergency shelter by a public or private agency. Some definitions of homelessness include persons living on a short-term basis in single-room-occupancy hotels or motels, or temporarily residing in social or health-service facilities without a permanent address. Housing the Homeless is a collection of case studies that bring together a variety of perspectives to help develop a clear understanding of the homelessness problem. The editors include information on the background and politics of the problem and descriptions of the current homeless population. The book concludes with a resource section, which highlights governmental policies and programs established to deal with the problem of homelessness.

Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy programming. Many people call themselves hackers, but few have the strong technical foundation needed to really push the envelope. Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundamentals of C programming from a hacker's perspective. The included LiveCD provides a complete Linux programming and debugging environment all without modifying your current operating system. Use it to follow along with the book's examples as you fill gaps in your knowledge and explore hacking techniques on your own. Get your hands dirty debugging code, overflowing buffers, hijacking network communications, bypassing protections, exploiting cryptographic weaknesses, and perhaps even inventing new exploits. This book will teach you how to: Program computers using C, assembly language, and shell scripts Corrupt system memory to run arbitrary code using buffer overflows and format strings Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening Outsmart common security measures like nonexecutable stacks and intrusion detection systems Gain access to a remote server using port-binding or connect-back shellcode, and alter a server's logging behavior to hide your presence Redirect network traffic, conceal open ports, and hijack TCP connections Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrix Hackers are always pushing the boundaries, investigating the unknown, and evolving their art. Even if you don't already know how to program, Hacking: The Art of Exploitation, 2nd Edition will give you a complete picture of programming, machine architecture, network communications, and existing hacking techniques. Combine this knowledge with the included Linux environment, and all you need is your own creativity.

Ecological economics addresses one of the fundamental flaws in conventional economics-its failure to consider biophysical and social reality in its analyses and equations. Ecological Economics: Principles and Applications is an introductory-level textbook that offers a pedagogically complete examination of this dynamic new field. As a workbook accompanying the text, this volume breaks new ground in applying the principles of ecological economics in a problem- or service-based learning setting. Both the textbook and this workbook are situated within a new interdisciplinary framework that embraces the linkages among economic growth, environmental degradation, and social inequity in an effort to guide policy in a way that respects fundamental human values. The workbook takes the approach a step further in placing ecological economic analysis within a systems perspective, in order to help students identify leverage points by which they can help to effect change. The workbook helps students to develop a practical, operational understanding of the principles and concepts explored in the text through real-world activities, and describes numerous case studies

The Fate of the Object traces the historical shift in focus from the "difficult" essential object of modernist theater, art, and poetry to its transformation as a sign in a postmodern field of signs. In modern art, the central object had been the abstract painting; in theater, the body of the actor; in poetry, the sonic, visual and grammatical elements of the poem. Spanning several disciplinary boundaries, this ambitious and pioneering book examines how the very process of refinement to locate the essential modernist object dissolves the figure of that object into its signifying ground. Jon Erickson argues that this historical shift from modern object to postmodern sign reflects significant transformations in capitalist society--among them the shift from a production economy to a service economy, the change from a sensually rich to a conceptually alienated cultural consciousness, and the rise of poststructuralist theory as the predominant determiner of value within contemporary art culture. Erickson examines the body as the central object of theater and performance through the theories of Craig, Sartre, Brecht, Artaud, and Grotowski. The art chapter discusses such artists as Malevich, Ad Reinhardt, Duchamp, Warhol and Kosuth, tracing the progression of the abstract painting to its reduction or disappearance in conceptualism and minimalism. The poetry chapter examines Pound's Imagism, Concrete and Sound Poetry, and the contributions of Gertrude Stein and the recent Language Poets. Finally, the author questions the role poststructuralist theory has played in the shift from modern object to postmodern sign and how it may affect our attitudes toward the materiality of the world.
