This collection of papers, celebrating the contributions of Swedish logician Dag Prawitz to Proof Theory, has been assembled from those presented at the Natural Deduction conference organized in Rio de Janeiro to honour his seminal research. Dag Prawitz's work forms the basis of intuitionistic type theory and his inversion principle constitutes the foundation of most modern accounts of proof-theoretic semantics in Logic, Linguistics and Theoretical Computer Science.

The range of contributions includes material on the extension of natural deduction with higher-order rules, as opposed to higher-order connectives, and a paper discussing the application of natural deduction rules to dealing with equality in predicate calculus. The volume continues with a key chapter summarizing work on the extension of the Curry-Howard isomorphism (itself a by-product of the work on natural deduction), via methods of category theory that have been successfully applied to linear logic, as well as many other contributions from highly regarded authorities. With an illustrious group of contributors addressing a wealth of topics and applications, this volume is a valuable addition to the libraries of academics in the multiple disciplines whose development has been given added scope by the methodologies supplied by natural deduction. The volume is representative of the rich and varied directions that Prawitz work has inspired in the area of natural deduction.

Brazil is the world's sixth-largest economy, and for the first three-quarters of the twentieth century was one of the fastest-growing countries in the world. While the country underwent two decades of unrelenting decline from 1975 to 1994, the economy has rebounded dramatically. How did this nation become an emerging power? Brazil in Transition looks at the factors behind why this particular country has successfully progressed up the economic development ladder. The authors examine the roles of beliefs, leadership, and institutions in the elusive, critical transition to sustainable development. Analyzing the last fifty years of Brazil's history, the authors explain how the nation's beliefs, centered on social inclusion yet bound by orthodox economic policies, led to institutions that altered economic, political, and social outcomes. Brazil's growth and inflation became less variable, the rule of law strengthened, politics became more open and competitive, and poverty and inequality declined. While these changes have led to a remarkable economic transformation, there have also been economic distortions and inefficiencies that the authors argue are part of the development process. Brazil in Transition demonstrates how a dynamic nation seized windows of opportunity to become a more equal, prosperous, and rules-based society.

This work aimed to study the Roman lamps collected in Alcacova de Santarem. The set is formed by a total of 393 unpublished fragments, although some references to some complete lamps in archaeological reports. Given the high fragmentation of the set, was not easy his classification and interpretation. Chronologically, the lamps was dated between the last quarter of the second century BC and the beginning of the fifth century AD. However, the largest volume of lychnological imports is from the High Empire. After the early second century AD, Scallabis seems to suffer a reduction of economic purchase which may be due to several factors, symptom that also is reflected by the Roman lamps."

This paper assesses and measures regulatory governance in 21 infrastructure regulators in Brazil. Regulatory Governance is decomposed into four main attributes: autonomy; decision-rules; means and tools; and accountability. A ranking is proposed and the main areas for improvement identified. A comparison of the proposed regulatory governance index and other indexes internationally available is performed. Section 2 sets up the analytical framework for the report, identifying key components of regulatory governance, namely, autonomy (political and financial), procedures for decision-making, tools and means (including personnel), and accountability. Section 3 assesses each of these components in practice, reporting the results of a survey with 21 regulatory agencies in Brazil, which was designed and implemented in 2005. Section 4 measures regulatory governance based on three related indexes, ranks the Brazilian regulators among themselves, and compares the proposed indexes with other two indicators available in the literature. Section 5 presents the conclusions.

Alvaro e um rapaz do campo que para ajudar a familia vem para Lisboa trabalhar nas obras dum amigo do pai, empreiteiro vigarista useiro em trapacas, cheques sem cobertura e dividas. Esforca-se e aprende rapidamente as artes da construcao civil ate que entende estar profissionalmente preparado, e comeca a trabalhar por conta propria. Ao longo dos anos, porventura servindo-se de metodos pouco ortodoxos, Alvaro faz fortuna e torna-se num construtor dono dum enorme patrimonio. Decidido a casar-se recusa os conselhos da mae, que gostaria de ter como nora uma mulher da sua aldeia porque no entender da velha senhora as mulheres da cidade sao todas umas galderias. Opiniao diferente tem o Alvaro, depois de ver como as raparigas da aldeia se comportam quando nao estao sob a vigilancia dos familiares nas aldeias remotas. Mais tarde o seu filho Marco, arquitecto, pouco mais faz na vida que servir de moco de recados ao pai, o que o inferioriza, mas ao mesmo tempo ele proprio nota em si pouca capacidade para se livrar daquilo que o oprime. Um dia o pai manda-o a Portimao com um cheque visado de dois milhoes de euros, outros dois milhoes em dinheiro e uma procuracao, para fazer a escritura de compra dum lote de terreno para construirem um grande edificio. Mas um construtor antigo amigo do pai, informado do negocio e do percurso do rapaz pelo gerente do banco onde levantam o dinheiro para o pagamento do terreno, contrata tres fulanos de ma catadura para assaltarem o Marco. A tentativa de assalto falha, Marco sofre um acidente, fica alguns dias em coma e sofre duma profunda amnesia que o impede de se recordar de tudo quanto a sua vida tem sido ou sequer, de quem e. Acolhido por uma familia cigana nomada que acredita que o ataque ao rapaz se possa dever a questoes relacionadas com drogas, e que por essa razao nao o entregam a policia ou num hospital com medo de represalias, Marco vive com eles. Ao ritmo lento das rodas das carrocas e do passo das mulas, ou sentados a noite em volta da fogueira, o rapaz vai sendo iniciado na cultura cale pelo patriarca da familia, que lhe demonstra e tenta incutir a pureza dos sentimentos e habitos calos, da sua inegociavel recusa em se submeterem a algum chefe no sentido que os padjos tem de chefe, ou de se disporem a acelerar um ritmo de vida que a partida lhes serve perfeitamente para viver e realizar a sua funcao nesta vida, simplesmente, viver em familia, sem nunca abandonar os seus, porque a vida so pode fazer sentido quando partilhada a cada momento com os nossos. Marco aprende que a verdadeira liberdade nao existe nem pode prescindir da participacao, do espirito de sacrificio, e da responsabilizacao. De todos para todos e entre todos os elementos duma familia, por sua vez a unidade primeira na cultura cigana. Neste livro, o autor tenta passar uma mensagem segundo a qual, a nossa sociedade hiper-desenvolvida(?) tem muito a reaprender com as sociedades tradicionais, verdadeiros repositorios das antigas tradicoes milenares, do amor pela liberdade, pela familia e pelo equilibrio nas relacoes sociais, sem esquecer que a perda ou adulteracao de conceitos como a responsabilidade por si mesmo e pelos seus, estao na base da destruicao e negacao da verdadeira felicidade. Que obviamente, apenas pode ser encontrada nas pequenas e simples coisas da vida, e sobretudo dentro de nos mesmos, se e quando estamos bem connosco e com os que sao nossos. Participacao, espirito de sacrificio e responsabilizacao conduzem a liberdade, tanto politica como social e familiar, e so em liberdade o ser humano pode atingir a plenitude da realizacao pessoal. Tenta o autor dar uma panoramica ainda que reduzida mas nao redutora, dos habitos e costumes ciganos, melhor, da cultura cigana, que tem sido mantida com uma certa pureza ao longo dos mais de mil anos que dura a epopeia deste povo, vindo da regiao do Punjab, na India, e que desde
