Book Description
This book introduces a new form of documentary film: the Geo-Doc, designed to maximize the influential power of the documentary film as an agent of social change. By combining the proven methods and approaches as evidenced through historical, theoretical, digital, and ecocritical investigations with the unique affordances of Geographic Information System technology, a dynamic new documentary form emerges, one tested in the field with the United Nations. This book begins with an overview of the history of the documentary film with attention given to how it evolved as an instrument of social change. It examines theories surrounding mobilizing the documentary film as a communication tool between filmmakers and policymakers. Ecocinema and its semiotic storytelling techniques are also explored for their unique approaches in audience engagement. The proven methods identified throughout the book are combined with the spatial and temporal affordances provided by GIS technology to create the Geo-Doc, a new tool for the activist documentarian.

Book Description
Early in the twentieth century, maternal and child welfare evolved from a private family responsibility into a matter of national policy. Molly Ladd-Taylor explores both the private and public aspects of child-rearing, using the relationship between them to cast new light on the histories of motherhood, the welfare state, and women's activism in the United States. Ladd-Taylor argues that mother-work, "women's unpaid work of reproduction and caregiving," motivated women's public activism and "maternalist" ideology. Mothering experiences led women to become active in the development of public health, education, and welfare services. In turn, the advent of these services altered mothering in many ways, including the reduction of the infant mortality rate.

Book Description
Prairie Fairies draws upon a wealth of oral, archival, and cultural histories to recover the experiences of queer urban and rural people in the prairies. Focusing on five major urban centres, Winnipeg, Saskatoon, Regina, Edmonton, and Calgary, Prairie Fairies explores the regional experiences and activism of queer men and women by looking at the community centres, newsletters, magazines, and organizations that they created from 1930 to 1985.? Challenging the preconceived narratives of queer history, Valerie J. Korinek argues that the LGBTTQ community has a long history in the prairie west, and that its history, previously marginalized or omitted, deserves attention. Korinek pays tribute to the prairie activists and actors who were responsible for creating spaces for socializing, politicizing, and organizing this community, both in cities and rural areas. Far from the stereotype of the isolated, insular Canadian prairies of small towns and farming communities populated by faithful farm families, Prairie Fairies historicizes the transformation of prairie cities, and ultimately the region itself, into a predominantly urban and diverse place.

Book Description
Rights, Wrongs, and Injustices is the first comprehensive account of the scope, foundations, and structure of remedial law in common law jurisdictions. The rules governing the kinds of complaints that common law courts will accept are generally well understood. However, the rules governing when and how they respond to such complaints are not. This book provides that understanding. It argues that remedies are judicial rulings, and that remedial law is the law governing their availability and content. Focusing on rulings that resolve private law disputes (for example, damages, injunctions, and restitutionary orders), this book explains why remedial law is distinctive, how it relates to substantive law, and what its foundational principles are. The book advances four main arguments. First, the question of what courts should do when individuals seek their assistance (the focus of remedial law) is different from the question of how individuals should treat one another in their day-to-day lives (the focus of substantive law). Second, remedies provide distinctive reasons to perform the actions they command; in particular, they provide reasons different from those provided by either rules or sanctions. Third, remedial law has a complex relationship to substantive law. Some remedies are responses to rights-threats, others to wrongs, and yet others to injustices. Further, remedies respond to these events in different ways: while many remedies (merely) replicate substantive duties, others modify substantive duties and some create entirely new duties. Finally, remedial law is underpinned by general principles-principles that cut across the traditional distinctions between so-called " and " remedies. Together, these arguments provide an understanding of remedial law that takes the concept of a remedy seriously, classifies remedies according to their grounds and content, illuminates the relationship between remedies and substantive law, and presents remedial law as a body of principles rather than a historical category.

Book Description
This book is both an examination of, and a contribution to, our understanding of the theoretical foundations of the common law of contract. Focusing on contemporary debates in contract theory, Contract Theory aims to help readers better understand the nature and justification of the general idea of contractual obligation, as well as the nature and justification of the particular rules that make up the law of contract. The book is in three parts. Part I introduces the idea of 'contract theory', and presents a framework for identifying, classifying, and evaluating contract theories. Part II describes and evaluates the most important general theories of contract; examples include promissory theories, reliance-based theories, and economic theories. In Part III, the theoretical issues raised by the various specific doctrines that make up the law of contract (e.g., offer and acceptance, consideration, mistake, remedies, etc.) are examined in separate chapters. The legal focus of the book is the common law of the United Kingdom, but the theoretical literature discussed is international in origin; the arguments discussed are thus relevant to understanding the law of other common law jurisdictions and, in many instances, to understanding the law of civil law jurisdictions as well.

Book Description
Depuis sa découverte en 1945, la Résonance Magnétique Nucléaire (RMN) a connu des développements spectaculaires. Cela va de l'étude structurale de molécules de taille de plus en plus importante à la production d'images. L'une des applications de la production d'images est l'imagerie par Résonance Magnétique (IRM) dont les répercussions en médecine sont considérables. Compte tenu de la variété de ses aspects expérimentaux et méthodologiques, et de l'éventail de ses applications qui ne cesse de s'élargir, la RMN est devenue une discipline à part entière. Cette deuxième édition fait le point sur les méthodes et les concepts les plus récents de la RMN (techniques multi-impuisionnelles et multidimensionnelles, traitement du signal) sans oublier les aspects plus traditionnels (structure des spectres et paramètres dynamiques). Les connaissances fondamentales sont développées dans un style accessible a tout étudiant de premier cycle scientifique. Des connaissances complémentaires (en mathématiques et mécanique quantique) sont présentées de façon rigoureuse sur le Web afin de satisfaire des étudiants plus spécialisés (deuxième et troisième cycles, écoles d'ingénieurs).
