Lectures on Lagrangian Torus Fibrations
Symington's almost toric fibrations have played a central role in symplectic geometry over the past decade, from Vianna's discovery of exotic Lagrangian tori to recent work on Fibonacci staircases. Four-dimensional spaces are of relevance in Hamiltonian dynamics, algebraic geometry, and mathematical string theory, and these fibrations encode the geometry of a symplectic 4-manifold in a simple 2-dimensional diagram. This text is a guide to interpreting these diagrams, aimed at graduate students and researchers in geometry and topology. First the theory is developed, and then studied in many examples, including fillings of lens spaces, resolutions of cusp singularities, non-toric blow-ups, and Vianna tori. In addition to the many examples, students will appreciate the exercises with full solutions throughout the text. The appendices explore select topics in more depth, including tropical Lagrangians and Markov triples, with a final appendix listing open problems. Prerequisites include familiarity with algebraic topology and differential geometry.
The Trauma Golden Hour
The Golden Hour is a well-established concept in emergency medicine, related to the critical period of one hour after an injury, accident or trauma. This term implies that the mortality rates increase substantially if efficient care is not provided within 60 minutes after the trauma. This book is intended as a practical manual in Trauma Care within the context of the golden hour, addressing all trauma types and all body parts. Readers will find essential decision-making algorithms and protocols with commentary for traumas, along with easily accessible information on how to treat patients in a very practical and handy fashion. Furthermore, the content is presented in a didactic way suitable f...
The Modern Brazilian Stage
Reading a play and watching it performed onstage are quite different experiences. Likewise, studying a country's theatrical tradition with reference only to playtexts overlooks the vital impact of a play's performance on the audience and on the whole artistic community. In this performance-centered approach to Brazilian theatre since the 1940s, David George explores a total theatrical language—the plays, the companies that produced them, and the performances that set a standard for all future stagings. George structures the discussion around several important companies. He begins with Os Comediantes, whose revolutionary 1943 staging of Nelson Rodrigues' Vestido de Noiva (Bridal Gown) broke...
Brazilian Theater, 1970-2010
How did Brazilian theater survive under the military dictatorship of 1964-1985? How did it change once the regime was over? This collection of new essays is the first to cover Brazilian theater during this period. Brazilian scholars and artists discuss the history of a theater community that not only resisted the regime but reinvented itself and continued to develop more sophisticated forms of expression even in the face of competition from television and other media. The contributors recount the struggle to stage meaningful plays at a time when some artists and intellectuals were exiled, others imprisoned, tortured or killed. With the return of democracy other important issues arose: how to ensure space for different practices and for regional theater, and how to continue producing international plays that could be meaningful for a Brazilian audience.
Presidents, Governors, and the Politics of Distribution in Federal Democracies
Tensions between central authorities and subnational units over centralization and fiscal autonomy are on top of the political agenda in many developing federal countries. This book examines historical changes in the balance between the resources that presidents and governors control and the policy responsibilities they have to deliver. It focuses on Argentina and Brazil, the most decentralized federal countries in Latin America, with the most powerful sub-national governments in the region. Using formal modelling, statistical tools, and comparative historical analyses, it examines substantive shifts in the allocation of resources and the distribution of administrative functions and explains under which conditions these changes occur. In doing so, it presents theoretical and comparative implications for the study of fiscal federalism and the functioning of developing federal democracies. This text will be of key interest to scholars and students of federalism, intergovernmental relations, decentralization, and sub-national politics and more broadly to those studying comparative politics, democratization, political elites, public policy and economics.
