Plano de Pormenor das Antas : que contributo para a sustentabilidade urbana?

Esta dissertação analisa a importância do Plano de Pormenor das Antas, e a sua influência no desenvolvimento sustentável da cidade do Porto, nomeadamente na zona Este. Inicialmente o trabalho centra-se na compreensão do conceito de desenvolvimento sustentável, bem como na sua evolução e adaptabilidade ao planeamento urbano. Foram de seguida analisadas propostas de bairros sustentáveis que tiveram repercussões a nível europeu, e identificadas as principais medidas adoptadas, bem como os seus resultados e dificuldades de implementação. A análise do caso de estudo – Plano de Pormenor das Antas-, é feita a partir da metodologia criada por Miguel Amado no seu livro “Planeamento Urbano Sustentável” (2009), sendo que o enfoque é colocado no que o autor designa por “factores ambientais na concepção”. Seguindo o raciocínio inverso ao apresentado no livro, que visa sobretudo consciencializar para um método de planeamento sustentável, tentamos verificar a presença ou ausência destes elementos na execução da proposta. Estes factores foram agrupados por temática (componente natural, componente social e componente urbana) e abordados tendo em conta as condicionantes do local. Numa fase final da dissertação é feita uma síntese á analise efectuada, tendo como contexto a base teórica e os casos exemplares estudados, que se traduz em várias considerações e conclusões sobre o objectivo principal do trabalho. Este trabalho visa a necessidade da abordagem dos factores de desenvolvimento sustentável no acto do planeamento territorial, e propõe-se como um contributo para um melhor planeamento urbano.

Educação e cidadania : exigências à formação docente

Um dos grandes desafios da educação encontra-se na formação inicial de professores; questão que ocasiona um fenômeno social preocupante dada a sua influência na qualidade do ensino. É fundamental olhar para o futuro pedagogo e refletir as exigências de uma formação voltada para atender aos chamados da sociedade em suas contradições sociais. Este estudo insere-se na linha de pesquisa Supervisão Pedagógica e Formação de Formadores, possui como temática central o curso de formação de professores com locus na graduação em Pedagogia e concretizou-se com uma pesquisa bibliográfica e uma pesquisa de campo de caráter qualiquantitativa. Para a sua realização analisamos o Projeto Pedagógico do Curso de Pedagogia da Instituição de Ensino Superior Mario Schenberg, aplicamos questionários semiestruturados aos alunos e egressos do curso e realizamos a observação participante. Esta investigação nos permitiu constatar nossas hipóteses levantadas, reforçando a nossa convicção de que as exigências da formação do pedagogo promovedoras de uma educação transformadora têm sua alavanca na formação inicial e que as habilidades e competências necessárias ao pedagogo, para que possa atuar em prol de uma educação para a cidadania, estão relacionadas ao desenvolvimento de saberes pedagógicos, metodológicos e conceituais, ou seja, uma sólida formação teórico-prática.

Ler um sintoma = Lire un symptôme

Este texto chama a atenção para o facto da psicanálise não ser só uma questão de saber escutar, mas também de saber ler, em particular de ler o real dos restos sintomáticos para além do sentido, privando o sintoma do sentido.

Las novelas de "los nuevos años": literatura e historia en Alfredo Pareja Diezcanseco (Del Fabulador)

El autor comenta la trilogía «Los nuevos años», de Alfredo Pareja Diezcanseco. La advertencia presenta los sueños de modernización del país, con su esperanza de mayor equidad e inclusión, El aire y los recuerdos es leída como una creación de singulares matices poéticos: el aire se vuelve portador de ilusiones y sueños de soluciones para el país, pero también se los lleva, con las frustraciones, desamparos y fracasos, Los poderes omnímodos narra los inicios de la era velasquista, saca el mejor provecho a situaciones y personajes, probando una madurez narrativa excepcional. Pareja retrata las dos grandes ciudades del país en estas novelas, pero también recorre los campos, episodios históricos de importancia son el pretexto para mostrar, ambiciosamente, los diversos y amplios sectores de la estructura social ecuatoriana, eventos y personajes que, a su vez, se encuentran en diálogo con otros sucesos del mundo contemporáneo de la época. El autor sostiene que puede hablarse de una tendencia globalizadora de Pareja en estas novelas, de un claro afán por «desenclaustrar» a la nación.

Seguridad y cooperación interamericana en la sub región andina (Tema Central)

Este artículo convoca a adoptar una posición equilibrada en el análisis de las dimensiones e implicaciones que las crisis individuales de los países andinos tienen para la seguridad subregional. El autor parte de la premisa de que EE.UU. carece de una política clara frente a los problemas de la subregión y sostiene que en este país existe una sensación de pérdida de control, que hace que el tema del narcotráfico se convierta en el único con resonancia política. El autor plantea la necesidad de desarrollar un enfoque multilateral que garantice la seguridad subregional, y coloca a la crisis colombiana como la más grave y preocupante.

Joaquín Gallegos Lara y «El síndrome de Falcón»: literatura, mestizaje e interculturalidad en el Ecuador (Dossier: Cuatro narradores del 30, relecturas en su centenario)

Los escritores ecuatorianos han creado un rico legado de imaginarios que apuntan a una identidad nacional que es, en el fondo, plurinacional e intercultural. Si bien los autores de la Generación del 30 plantearon con su narrativa un proyecto de nación que incluía a las diferentes culturas que la habitan –proyecto mestizo fallido, sin embargo, en tanto anulaba las diferencias y consagraba las desigualdades–, el protagonismo social de estas culturas en la década de los 90 complementa la propuesta surgida desde lo literario en los años 30. Adicionalmente, la auto-representación política actual de dichos grupos pone en tela de juicio criterios del ámbito cultural contemporáneo, uno de ellos es el del llamado «Síndrome de Falcón», que pretende ser una metáfora de la carga de representar a sectores sociales desfavorecidos, que ha pesado sobre los narradores ecuatorianos durante el siglo XX. Todo ello empuja el proceso de reconfiguración del panorama de la cultura ecuatoriana: la creciente participación de estas voces antes silenciadas, así como la emergencia de otras formas de contemplar al mundo natural, que suscitan nuevas lecturas de novelas clásicas como Don Goyo o La isla virgen de Demetrio Aguilera-Malta.

La política exterior colombiana en materia de integración (Tema Central)

La agenda internacional de Colombia, durante los siete años de Uribe, se ha securitizado y terrorizado en el ámbito temático y se ha concentrado y bilateralizado en Estados Unidos desde un punto de vista geográfico. En consecuencia, ni Latinoamérica ni Europa han merecido la atención de otros tiempos. Por ello, se califica la actual política exterior de Colombia, que determina hoy las estrategias de integración de Colombia, de neo Respice Polum (mirar al polo).

The Ethics of Ethics Reviews in Global Health Research: Case Studies Applying a New Paradigm

With increasing calls for global health research there is growing concern regarding the ethical challenges encountered by researchers from high-income countries (HICs) working in low or middle-income countries (LMICs). There is a dearth of literature on how to address these challenges in practice. In this article, we conduct a critical analysis of three case studies of research conducted in LMICs.We apply emerging ethical guidelines and principles specific to global health research and offer practical strategies that researchers ought to consider. We present case studies in which Canadian health professional students conducted a health promotion project in a community in Honduras; a research capacity-building program in South Africa, in which Canadian students also worked alongside LMIC partners; and a community-university partnered research capacity-building program in which Ecuadorean graduate students, some working alongside Canadian students, conducted community-based health research projects in Ecuadorean communities.We examine each case, identifying ethical issues that emerged and how new ethical paradigms being promoted could be concretely applied.We conclude that research ethics boards should focus not only on protecting individual integrity and human dignity in health studies but also on beneficence and non-maleficence at the community level, explicitly considering social justice issues and local capacity-building imperatives.We conclude that researchers from HICs interested in global health research must work with LMIC partners to implement collaborative processes for assuring ethical research that respects local knowledge, cultural factors, the social determination of health, community participation and partnership, and making social accountability a paramount concern.

How to avoid a double-dip recession in the eurozone. CEPS Commentary, 15 November 2012

This CEPS Commentary argues that the way in which the burden of adjustment to the imbalances in the eurozone is borne almost exclusively by the deficit countries in the periphery produces a deflationary bias in the region as a whole. Against the threat of double-dip recession, Paul De Grauwe asserts that the adjustment could be done differently and calls for implementation of a more symmetric macroeconomic policy that reduces the deflationary bias.

The Gulf Cooperation Council as a New Regional Power: Time for the EU to Propose a Strategic Partnership. Bruges Regional Integration & Global Governance Papers 3/2012, November 2012

The Gulf Cooperation Council (GCC) is a de facto regional power in the Arab world. Its role has been crucial in some of the outcomes of the Arab Spring. The GCC countries have been very pragmatic in dealing with the uprisings, avoiding any revolutionary spill-over throughout the Gulf region. This paper examines to what extent the policies of the European Union (EU) in the Gulf have changed since the beginning of the Arab Spring. It argues that despite the calls by the European Parliament and by the High Representative Baroness Ashton to improve the relationship, the EU’s support for a new policy in the Gulf after the Arab Spring is stalling, and little new or concrete has been achieved. The paper concludes that the Union needs a reinforced partnership that merges the various EU policies in the region into a single strategic partnership with the Arab countries.

Evidence Suggesting that Ivory-billed Woodpeckers (Campephilus principalis) Exist in Florida

The Ivory-billed Woodpecker (Campephilus principalis) disappeared from the forests of southeastern North America in the early 20th Century and for more than 50 years has been widely considered extinct. On 21 May 2005, we detected a bird that we identified as an Ivory-billed Woodpecker in the mature swamp forest along the Choctawhatchee River in the panhandle of Florida. During a subsequent year of research, members of our small search team observed birds that we identified as Ivory-billed Woodpeckers on 14 occasions. We heard sounds that matched descriptions of Ivory-billed Woodpecker acoustic signals on 41 occasions. We recorded 99 putative double knocks and 210 putative kent calls. We located cavities in the size range reported for Ivory-billed Woodpeckers and larger than those of Pileated Woodpeckers (Dryocopus pileatus) that have been reported in the literature or that we measured in Alabama. We documented unique foraging signs consistent with the feeding behavior of Ivory-billed Woodpeckers. Our evidence suggests that Ivory-billed Woodpeckers may be present in the forests along the Choctawhatchee River and warrants an expanded search of this bottomland forest habitat.

Running Climate Models On The NERC Cluster Grid Using G-Rex

Compute grids are used widely in many areas of environmental science, but there has been limited uptake of grid computing by the climate modelling community, partly because the characteristics of many climate models make them difficult to use with popular grid middleware systems. In particular, climate models usually produce large volumes of output data, and running them usually involves complicated workflows implemented as shell scripts. For example, NEMO (Smith et al. 2008) is a state-of-the-art ocean model that is used currently for operational ocean forecasting in France, and will soon be used in the UK for both ocean forecasting and climate modelling. On a typical modern cluster, a particular one year global ocean simulation at 1-degree resolution takes about three hours when running on 40 processors, and produces roughly 20 GB of output as 50000 separate files. 50-year simulations are common, during which the model is resubmitted as a new job after each year. Running NEMO relies on a set of complicated shell scripts and command utilities for data pre-processing and post-processing prior to job resubmission. Grid Remote Execution (G-Rex) is a pure Java grid middleware system that allows scientific applications to be deployed as Web services on remote computer systems, and then launched and controlled as if they are running on the user's own computer. Although G-Rex is general purpose middleware it has two key features that make it particularly suitable for remote execution of climate models: (1) Output from the model is transferred back to the user while the run is in progress to prevent it from accumulating on the remote system and to allow the user to monitor the model; (2) The client component is a command-line program that can easily be incorporated into existing model work-flow scripts. G-Rex has a REST (Fielding, 2000) architectural style, which allows client programs to be very simple and lightweight and allows users to interact with model runs using only a basic HTTP client (such as a Web browser or the curl utility) if they wish. This design also allows for new client interfaces to be developed in other programming languages with relatively little effort. The G-Rex server is a standard Web application that runs inside a servlet container such as Apache Tomcat and is therefore easy to install and maintain by system administrators. G-Rex is employed as the middleware for the NERC1 Cluster Grid, a small grid of HPC2 clusters belonging to collaborating NERC research institutes. Currently the NEMO (Smith et al. 2008) and POLCOMS (Holt et al, 2008) ocean models are installed, and there are plans to install the Hadley Centre’s HadCM3 model for use in the decadal climate prediction project GCEP (Haines et al., 2008). The science projects involving NEMO on the Grid have a particular focus on data assimilation (Smith et al. 2008), a technique that involves constraining model simulations with observations. The POLCOMS model will play an important part in the GCOMS project (Holt et al, 2008), which aims to simulate the world’s coastal oceans. A typical use of G-Rex by a scientist to run a climate model on the NERC Cluster Grid proceeds as follows :(1) The scientist prepares input files on his or her local machine. (2) Using information provided by the Grid’s Ganglia3 monitoring system, the scientist selects an appropriate compute resource. (3) The scientist runs the relevant workflow script on his or her local machine. This is unmodified except that calls to run the model (e.g. with “mpirun”) are simply replaced with calls to "GRexRun" (4) The G-Rex middleware automatically handles the uploading of input files to the remote resource, and the downloading of output files back to the user, including their deletion from the remote system, during the run. (5) The scientist monitors the output files, using familiar analysis and visualization tools on his or her own local machine. G-Rex is well suited to climate modelling because it addresses many of the middleware usability issues that have led to limited uptake of grid computing by climate scientists. It is a lightweight, low-impact and easy-to-install solution that is currently designed for use in relatively small grids such as the NERC Cluster Grid. A current topic of research is the use of G-Rex as an easy-to-use front-end to larger-scale Grid resources such as the UK National Grid service.

Controlling nitrate pollution: an integrated approach

The introduction of the EU Water Framework Directive requires policy to address non-point source pollution as part of an overall integrated strategy to improve the ecological status of water bodies. In this paper, we combine an economic optimisation framework with a dynamic simulation model of N transport in the Kennet Catchment to link decisions taken at the farm level to reductions in nitrate concentrations in the River Kennet. We examine a variety of policies targeted at reducing fertiliser use and changing the way in which farm land is used. We find that a tax on nitrogen emerges as the best policy both in terms of cost- and environmental effectiveness. Such a policy involves a considerable reduction in fertiliser use, as well as, a restructuring of land-use away from arable towards increased use of set-aside. Budgetary implications of such a radical move towards set-aside would be huge and hence unlikely to be politically palatable given the objective of reducing the EU budgetary allocation to agriculture. Additionally, the current rise in world demand for food may also mitigate calls for increasing the proportion of land taken out of agricultural production. Although the study succeeds in establishing a link between actions on the farm and nitrate concentrations in the stream water, further work is required to explore the effect of the retention of nitrates in the unsaturated zone and groundwater on this link.

Diversity and difference in the everyday lives of Ugandan street children: The significance of age and gender for understanding the use of space

Childhood is characterised by diversity and difference across and within societies. Street children have a unique relationship to the urban environment evident through their use of the city. The everyday geographies that street children produce are diversified through the spaces they frequent and the activities they engage in. Drawing on a range of children-centred qualitative methods, this article focuses on street children's use of urban space in Kampala, Uganda. The article demonstrates the importance of considering variables such as gender and age in the analysis of street children's socio-spatial experiences, which, to date, have rarely been considered in other accounts of street children's lives. In addition the article highlights the need for also including street children's individuality and agency into understanding their use of space. The article concludes by arguing for policies to be sensitive to the diversity that characterises street children's lives and calls for a more nuanced approach where policies are designed to accommodate street children's age and gender differences, and their individual needs, interests and abilities.
