En este libro presenta una revisión de la situación de inseguridad y violencia que se desarrolla en las ciudades de América Latina, así como una revisión de las políticas públicas de seguridad y las acciones institucionales emprendidas por los gobiernos locales para superar los problemas de inseguridad en las dieciocho ciudades del continente que se han tomado como referentes en la investigación. No es el interés de la obra cuestionar la eficacia o no de las políticas y de su implementación, sino, más bien, revisar las posibilidades que estas ofrecen como prácticas de aprendizaje y enseñanza útiles para la disminución de la violencia y el tratamiento de la delincuencia común y organizada, en la ruta de la formulación de políticas públicas de seguridad ciudadana cada vez más eficientes.

Instead of the usual apologetic treatment found in legal doctrine, linked to the determinacy, immutability or predictability of norms, this book treats legal certainty innovatively, holistically and in depth. Using a method at once analytical and functional, Professor Ávila examines the structural elements of legal certainty, from its definition and foundations to its various dimensions, normative forces and efficacies, citing a wealth of examples from case law to support each of the theses defended. No subject is more important and topical than legal certainty. Problems relating to lack of understanding, instability and unpredictability of law intensify day by day everywhere, in civil law and common law countries alike. Normative sources are increasingly diverse in origin (national, international, community) and multiple in nature (legal, contractual, jurisprudential). They change constantly, and present increasingly frequent problems of ambiguity and vagueness that significantly hinder their comprehension. This state of affairs, which to a greater or lesser extent is true of any legal order, justifies a return to the subject of legal certainty. In this book, essential questions are answered such as: Legal certainty in what sense? Certainty of what, for whom, in whose vision and by whom? When, to what extent, and to what end? “(...) it is probably the most comprehensive and systematic study ever produced on this subject using the analytical method.” (Riccardo Guastini, Professor of Jurisprudence, University of Genoa, Italy)

The expression 'the criminal question' does not at present have much currency in English-language criminology. The term was carried across from Italian debates about the orientation of criminology, and in particular debates about what came to be called critical criminology. One definition offered early in the debate described it as 'an area constituted by actions, institutions, policies and discourses whose boundaries shift'. According to this writer, crime, and the cultural and symbolic significance carried by law and criminal justice, is an integral aspect of the criminal question. 'The criminal question' draws attention to the specific location and constitution of a given field of forces, and the themes, issues, dilemmas and debates that compose it. At the same time it enables connections to be made between these embedded realities and the wider, conceivably global, contours of influence and flows of power with which it connects. This in turn raises many questions. How far do the responses to crime and punishment internationally flow from and owe their contemporary shape to the cultural and economic transformations now widely known as 'globalisation'? How can something that is in significant ways embedded, situated, and locally produced also travel? What is not in doubt is that it does travel - and travel with serious consequences. The international circulation of discourses and practices has become a pressing issue for scholars who try to understand their operation in their own particular cultural contexts. This collection of essays seeks a constructive comparative view of these tendencies to convergence and divergence.

Vacant urban land--the product of land market activity, the actions of private agents, and the policies of public agents--is an important challenge for policy makers. Vacant lots on the urban fringe and in central and interstitial areas have affected growth patterns in Latin America. Contributors to this book analyze the problems and opportunities related to vacant urban land in five cities: Buenos Aires, Argentina; Rio de Janeiro, Brazil; Quito, Ecuador; Lima, Perú; and San Salvador, El Salvador.
