This book brings together several systems-level approaches to the consideration of the interaction of livelihood choices, natural resource management and participatory action research on sustainable development. By focusing on these approaches to community change, the volume hopes to encourage readers to consider how they might adopt methods such as Sustainable Livelihoods Approach (SLA), Community Capitals Framework (CCF) and Participatory Action Research (PAR) in their own research, practice and teaching. Thus, this volume will engage readers in reflection about the importance of systems-level approaches that address poverty from the perspective of the poor, natural resource management that maintains the resource for future generations, and the engagement of local people in designing and implementing, and thus owning, strategies that address equity as well as economic security and the environment. This book was originally published as a special issue of Community Development.

The Optical Unconscious is a pointed protest against the official story of modernism and against the critical tradition that attempted to define modern art according to certain sacred commandments and self-fulfilling truths. The account of modernism presented here challenges the vaunted principle of "vision itself." And it is a very different story than we have ever read, not only because its insurgent plot and characters rise from below the calm surface of the known and law-like field of modernist painting, but because the voice is unlike anything we have heard before. Just as the artists of the optical unconscious assaulted the idea of autonomy and visual mastery, Rosalind Krauss abandons the historian's voice of objective detachment and forges a new style of writing in this book: art history that insinuates diary and art theory, and that has the gait and tone of fiction. The Optical Unconscious will be deeply vexing to modernism's standard-bearers, and to readers who have accepted the foundational principles on which their aesthetic is based. Krauss also gives us the story that Alfred Barr, Meyer Shapiro, and Clement Greenberg repressed, the story of a small, disparate group of artists who defied modernism's most cherished self-descriptions, giving rise to an unruly, disruptive force that persistently haunted the field of modernism from the 1920s to the 1950s and continues to disrupt it today. In order to understand why modernism had to repress the optical unconscious, Krauss eavesdrops on Roger Fry in the salons of Bloomsbury, and spies on the toddler John Ruskin as he amuses himself with the patterns of a rug; we find her in the living room of Clement Greenberg as he complains about "smart Jewish girls with their typewriters" in the 1960s, and in colloquy with Michael Fried about Frank Stella's love of baseball. Along the way, there are also narrative encounters with Freud, Jacques Lacan, Georges Bataille, Roger Caillois, Gilles Deleuze, and Jean-François Lyotard. To embody this optical unconscious, Krauss turns to the pages of Max Ernst's collage novels, to Marcel Duchamp's hypnotic Rotoreliefs, to Eva Hesse's luminous sculptures, and to Cy Twombly's, Andy Warhol's, and Robert Morris's scandalous decoding of Jackson Pollock's drip pictures as "Anti-Form." These artists introduced a new set of values into the field of twentieth-century art, offering ready-made images of obsessional fantasy in place of modernism's intentionality and unexamined compulsions.

An up-to-date compilation of the theoretical background and practical procedures involved in lignin characterization. Whenever possible, the procedures are presented in sufficient detail to enable the reader to perform the analysis solely by following the step-by-step description. The advantages and limitations of individual methods are discussed and, more importantly, illustrated by typical analytical data in comparison to results obtained from other methods. This handbook serves the need of researchers and other professionals in academia, the pulp and paper industry as well as allied industries. It is equally useful for those with no previous experience in lignin or lignocellulosics.

The sociological study of economic activity has witnessed a significant resurgence. Recent texts have chronicled economic sociology's nineteenth-century origins while pointing to the importance of context and power in economic life, yet the field lacks a clear understanding of the role that concepts at different levels of abstraction play in its organization. Economic Sociology fills this critical gap by surveying the current state of the field while advancing a framework for further theoretical development. Alejandro Portes examines economic sociology's principal assumptions, key explanatory concepts, and selected research sites. He argues that economic activity is embedded in social and cultural relations, but also that power and the unintended consequences of rational purposive action must be factored in when seeking to explain or predict economic behavior. Drawing upon a wealth of examples, Portes identifies three strategic sites of research--the informal economy, ethnic enclaves, and transnational communities--and he eschews grand narratives in favor of mid-range theories that help us understand specific kinds of social action. The book shows how the meta-assumptions of economic sociology can be transformed, under certain conditions, into testable propositions, and puts forward a theoretical agenda aimed at moving the field out of its present impasse.

Salvadorean society is shocked by the gruesome murder of a young upper-class woman, and no one more so than her best friend Laura. In her first-person solo narration, Laura rattles on and on about her disbelief and horror at the evils all around her—but who’s that in the mirror? Laura Rivera can’t believe what has happened. Her best friend has been killed in cold blood in the living room of her home, in front of her two young daughters! Nobody knows who pulled the trigger, but Laura will not rest easy until she finds out. Her dizzying, delirious, hilarious, and blood-curdling one-sided dialogue carries the reader on a rough and tumble ride through the social, political, economic, and sexual chaos of post-civil war San Salvador. A detective story of pulse-quickening suspense, The She-Devil in the Mirror is also a sober reminder that justice and truth are more often than not illusive. Castellanos Moya’s relentless, obsessive narrator—female, rich, paranoid, wonderfully perceptive, and, in the end, fabulously unreliable—paints with frivolous profundity a society in a state of collapse. Castellanos Moya’s Senselessness was acclaimed “an innovative and invigoratingly twisted piece of art” (Village Voice) and “a brilliantly crafted moral fable, as if Kafka had gone to Latin America for his source materials” (Russell Banks).
