Municipalismo e política urbana: a Influência da União na Política Urbana Municipal

A política urbana, em seus vetores de regulação, serviços públicos e fomento, é o conjunto de princípios, diretrizes e ações que orientam a atividade econômica de urbanização, podendo determinar condutas à iniciativa privada através da função social da propriedade. Por afetar diretamente a vida das pessoas e a conformação da propriedade nas cidades, a política urbana é, por essência, municipal. A tradição da força municipalista no Brasil, que data do período imperial, ainda que em alguns momentos sufocada, manejou tornar os Municípios entes federados, assegurando- lhes, na Constituição de 1988, autonomia e atribuições, como a execução da política urbana traçada em diretrizes gerais por leis nacionais. As diretrizes nacionais para a política urbana, elaboradas em processo participativo, deveria pautar as ações da União, Estados e Municípios no tocante aos três mencionados vetores. No entanto, notando-se a quase total ausência dos Estados, verifica-se que a União, após a Constituição de 1988, rompeu com a própria ideologia de planejamento construída com a criação do Ministério das Cidades pelo Governo Lula e, atropelando o tempo de formação das diretrizes nacionais da política urbana, lançou programas de fomento a moradias e saneamento básico, cuja execução deve ser organizada pelos Municípios, que são tecnicamente frágeis e carentes de recursos para implementar a própria política urbana. Este recorte temático permite estudar a atuação mais recente da União em política urbana que, mesmo pretendendo dar conta de mazelas históricas do país, não destoa muito do período centralizador de formulação da política urbana do Regime Militar. Em Municipalismo e Política Urbana, analisa-se a influência da União na Política Urbana Municipal.

Death or taxes? The political economy of sanitation expenditure in nineteenth-century Britain

This thesis consists of three papers studying the relationship between democratic reform, expenditure on sanitation public goods and mortality in Britain in the second half of the nineteenth century. During this period decisions over spending on critical public goods such as water supply and sewer systems were made by locally elected town councils, leading to extensive variation in the level of spending across the country. This dissertation uses new historical data to examine the political factors determining that variation, and the consequences for mortality rates.

The first substantive chapter describes the spread of government sanitation expenditure, and analyzes the factors that determined towns' willingness to invest. The results show the importance of towns' financial constraints, both in terms of the available tax base and access to borrowing, in limiting the level of expenditure. This suggests that greater involvement by Westminster could have been very effective in expediting sanitary investment. There is little evidence, however, that democratic reform was an important driver of greater expenditure.

Chapter 3 analyzes the effect of extending voting rights to the poor on government public goods spending. A simple model predicts that the rich and the poor will desire lower levels of public goods expenditure than the middle class, and so extensions of the right to vote to the poor will be associated with lower spending. This prediction is tested using plausibly exogenous variation in the extent of the franchise. The results strongly support the theoretical prediction: expenditure increased following relatively small extensions of the franchise, but fell once more than approximately 50% of the adult male population held the right to vote.

Chapter 4 tests whether the sanitary expenditure was effective in combating the high mortality rates following the Industrial Revolution. The results show that increases in urban expenditure on sanitation-water supply, sewer systems and streets-was extremely effective in reducing mortality from cholera and diarrhea.

Reform of Spain's profesional services market: Implementation of the EU Services Directive

The implementation of the European Commission Services Directive initiated the modernization process of services markets within the European Union. The objective was to guarantee the creation of a single market by ensuring the freedom of establishment and circulation. The transposition of the Directive in Spain triggered an initial wave of reforms in the Spanish legal system. A second package of reforms is currently underway, following recommendations by the EC, IMF and OECD, which highlight the relative lack of competition in Spain’s services as one of the major imbalances in its economy, alongside the public deficit and unemployment. Both the implemented and planned reforms represent a major step forward. Nevertheless, the government has recently announced modifications to the draft bill of the Professional Services and Associations Law, which is expected to soon be submitted for parliamentary debate and approval. Taking into consideration modifications already introduced, together with anticipated further changes, it will be important to maintain the main points of the draft bill and to introduce a deeper review of the legal framework for professional services, of the professional associations themselves, and for the activities that are subject to compulsory membership within a professional association. Spain’s territorial map of professional associations must too be redrawn.

Disseminação de dados estatísticos georeferenciados através de WEB services e software livre.

Diferentes organizações públicas e privadas coletam e disponibilizam uma massa de dados sobre a realidade sócio-econômica das diferentes nações. Há hoje, da parte do governo brasileiro, um interesse manifesto de divulgar uma gama diferenciada de informações para os mais diversos perfis de usuários. Persiste, contudo, uma série de limitações para uma divulgação mais massiva e democrática, entre elas, a heterogeneidade das fontes de dados, sua dispersão e formato de apresentação pouco amigável. Devido à complexidade inerente à informação geográfica envolvida, que produz incompatibilidade em vários níveis, o intercâmbio de dados em sistemas de informação geográfica não é problema trivial. Para aplicações desenvolvidas para a Web, uma solução são os Web Services que permitem que novas aplicações possam interagir com aquelas que já existem e que sistemas desenvolvidos em plataformas diferentes sejam compatíveis. Neste sentido, o objetivo do trabalho é mostrar as possibilidades de construção de portais usando software livre, a tecnologia dos Web Services e os padrões do Open Geospatial Consortium (OGC) para a disseminação de dados espaciais. Visando avaliar e testar as tecnologias selecionadas e comprovar sua efetividade foi desenvolvido um exemplo de portal de dados sócio-econômicos, compreendendo informações de um servidor local e de servidores remotos. As contribuições do trabalho são a disponibilização de mapas dinâmicos, a geração de mapas através da composição de mapas disponibilizados em servidores remotos e local e o uso do padrão OGC WMC. Analisando o protótipo de portal construído, verifica-se, contudo, que a localização e requisição de Web Services não são tarefas fáceis para um usuário típico da Internet. Nesta direção, os trabalhos futuros no domínio dos portais de informação geográfica poderiam adotar a tecnologia Representational State Transfer (REST).

Alterations of the global water cycle and their effects on river structure, function and services

River structure and functioning are governed naturally by geography and climate but are vulnerable to natural and human-related disturbances, ranging from channel engineering to pollution and biological invasions. Biological communities in river ecosystems are able to respond to disturbances faster than those in most other aquatic systems. However, some extremely strong or lasting disturbances constrain the responses of river organisms and jeopardise their extraordinary resilience. Among these, the artificial alteration of river drainage structure and the intense use of water resources by humans may irreversibly influence these systems. The increased canalisation and damming of river courses interferes with sediment transport, alters biogeochemical cycles and leads to a decrease in biodiversity, both at local and global scales. Furthermore, water abstraction can especially affect the functioning of arid and semi-arid rivers. In particular, interception and assimilation of inorganic nutrients can be detrimental under hydrologically abnormal conditions. Among other effects, abstraction and increased nutrient loading might cause a shift from heterotrophy to autotrophy, through direct effects on primary producers and indirect effects through food webs, even in low-light river systems. The simultaneous desires to conserve and to provide ecosystem services present several challenges, both in research and management.

Automatically exposing OpenLifeData via SADI semantic Web Services

Background: Two distinct trends are emerging with respect to how data is shared, collected, and analyzed within the bioinformatics community. First, Linked Data, exposed as SPARQL endpoints, promises to make data easier to collect and integrate by moving towards the harmonization of data syntax, descriptive vocabularies, and identifiers, as well as providing a standardized mechanism for data access. Second, Web Services, often linked together into workflows, normalize data access and create transparent, reproducible scientific methodologies that can, in principle, be re-used and customized to suit new scientific questions. Constructing queries that traverse semantically-rich Linked Data requires substantial expertise, yet traditional RESTful or SOAP Web Services cannot adequately describe the content of a SPARQL endpoint. We propose that content-driven Semantic Web Services can enable facile discovery of Linked Data, independent of their location. Results: We use a well-curated Linked Dataset - OpenLifeData - and utilize its descriptive metadata to automatically configure a series of more than 22,000 Semantic Web Services that expose all of its content via the SADI set of design principles. The OpenLifeData SADI services are discoverable via queries to the SHARE registry and easy to integrate into new or existing bioinformatics workflows and analytical pipelines. We demonstrate the utility of this system through comparison of Web Service-mediated data access with traditional SPARQL, and note that this approach not only simplifies data retrieval, but simultaneously provides protection against resource-intensive queries. Conclusions: We show, through a variety of different clients and examples of varying complexity, that data from the myriad OpenLifeData can be recovered without any need for prior-knowledge of the content or structure of the SPARQL endpoints. We also demonstrate that, via clients such as SHARE, the complexity of federated SPARQL queries is dramatically reduced.
