Regional growth in Europe: The role of European and national policies

We conduct a systematic study of the impact of European Union (EU) regional policies on regional economic growth that controls for national policies and geographic characteristics. Special care is taken in distinguishing between the impact of EU policies and of national policies on economic growth. Our empirical study tries to answer two different questions. First, is there convergence across EU regions, and if so, do regions converge to a common European steady-state or to a national one? Second, how do European and national policies affect regional growth? We find evidence of regional convergence at the national level but not at the European level. In addition we find that trade openness at the national level is associated with regional convergence while European regional policies contribute, though weakly, to regional convergence. Our results suggest that policies that foster market integration – and convergence to a common steady-state - such as the promotion of labour and capital movements across countries and common regulatory policies are as important for European-wide regional convergence as regional structural funds.

Islão ambivalente: a construção identitária dos Muçulmanos sob o poder colonial português

Este artigo procura contribuir para o estudo dos processos históricos que têm tomado populações muçulmanas como alvos preferenciais da governança e da análise políticas. Baseado em documentação de arquivos portugueses e franceses, o artigo procura assinalar as mais notórias representações identitárias que ideólogos e membros do aparelho colonial português construíram em torno dos grupos islâmicos da Guiné-Bissau e de Moçambique, incidindo especialmente nesta última colónia. Tais imagens articularam-se com as estratégias de governação das populações muçulmanas num quadro colonialista, sobretudo após a eclosão das guerras coloniais. O artigo defende que a posição semiperiférica de Portugal no sistema-mundo conferiu às suas representações e estratégias identitárias, nomeadamente as que se reportam aos muçulmanos colonizados, um carácter de profunda ambivalência.

Relações sinuosas: Portugal e o mundo árabe, 1950-1973

Nas três últimas décadas do colonialismo português, as políticas destinadas às populações muçulmanas da Guiné e de Moçambique passaram da hostilidade mais ou menos aberta para uma estratégia de sedução, com vista a promover um “Islão português” e a usar certos sectores muçulmanos no combate aos movimentos nacionalistas. Esta transição teve também uma componente transnacional, na medida em que se quis alargar a intervenção portuguesa a um espaço estratégico designado como “mundo islâmico”. O presente artigo procura analisar essa intervenção, debruçando-se sobre o pensamento geopolítico que a informou e as suas aplicações diplomáticas, em particular no relacionamento com os países árabes.

O ensino na política islâmica do Moçambique colonial: da ansiedade islamofóbica à miragem do ‘Islão português

Ao longo da trajectória colonial, a abordagem do Islão moçambicano pelas autoridades portuguesas passou de uma islamofobia renitente, por vezes com gestos esporádicos de aproximação, para um programa de sedução das lideranças islâmicas, desenvolvido entre 1968 e 1974. Partindo deste quadro evolutivo, o presente artigo procura traçar a transformação das políticas dedicadas ao ensino islâmico em Moçambique. Se o tempo islamofóbico viu nesse ensino um factor de “desnacionalização” da população colonizada, o período seguinte encarou-o como obstáculo à ideia de um “Islão português”, obstáculo que alguns pensaram contornar subordinando as escolas corânicas ao sistema oficial de ensino. O artigo analisa também as tensões suscitadas por estas políticas, focando a reacção de hostilidade por parte do meio católico mais conservador

A cor como abrigo: a arquitectura como cuidado

A presente tese intitulada “A cor como abrigo: a arquitectura como cuidado” tem por objectivo fortalecer a ligação entre a “Teoria das Cores” de Goethe e a arquitectura. Para isso a nossa estratégia foi recuperar os conceitos de espaço e corpo. Ambos começam por ser tomados como realidades físicas mas pouco a pouco vai-se mostrando que tal coisa como uma abordagem ‘puramente física’ do espaço e do corpo não é possível - talvez porque não exista. Mesmo a medicina (ao contrario do que possamos pensar primeiro) é uma ciência que não só reconhece o carácter diáfano do corpo como diariamente luta para ir além de uma concepção do corpo enquanto coisa física por perceber que o corpo é determinado por formas e funções mas sobretudo como tomado por forças. Um exemplo extremo desta interacção entre espaço e corpo (ligados através da arquitectura), onde o carácter diáfano de ambos ganha evidência, é na arquitectura de hospitais, que abordamos por último: “o que é um espaço vivido que tem por principal função restaurar o corpo do seu estado de doença?” As referencias principais são J.W. Goethe, Ludwig Wittgenstein, Edmund Husserl, Gilles Deleuze, Christian Norberg- Schulz, Frank Lloyd Wright and Tadao Ando. *********************************************************************This PhD research thesis titled: "Colour as shelter: architecture as care" has as its main goal to strengthen an existing relation between Goethe's Theory of Colours and Architecture. In order to do that our strategy was to use space and body as guiding concepts. Both start as being considered from a pure physical point of view but as our theme develops we see that a “pure physical point of view” concerning space and body it is not possible – perhaps because it does not exist. Medicine (unlike we may think at first) it is a science that not only acknowledges the diaphanous character of the body as daily, tries to go beyond the conception of body as physical thing understanding that the body is determined by forms and functions but mostly taken by forces. An extreme example of the interaction between space and body (linked through architecture), where the diaphanous character of both is evident, is Healthcare architecture: "what is a lived space that has as main function to restore the body of its illness"? Main references are: J.W. Goethe, Ludwig Wittgenstein, Edmund Husserl, Gilles Deleuze, Christian Norberg-Schulz, Frank Lloyd Wright and Tadao Ando.

About using serious games to teach (Portuguese) sign language

Sign language is the form of communication used by Deaf people, which, in most cases have been learned since childhood. The problem arises when a non-Deaf tries to contact with a Deaf. For example, when non-Deaf parents try to communicate with their Deaf child. In most cases, this situation tends to happen when the parents did not have time to properly learn sign language. This dissertation proposes the teaching of sign language through the usage of serious games. Currently, similar solutions to this proposal do exist, however, those solutions are scarce and limited. For this reason, the proposed solution is composed of a natural user interface that is intended to create a new concept on this field. The validation of this work, consisted on the implementation of a serious game prototype, which can be used as a source for learning (Portuguese) sign language. On this validation, it was first implemented a module responsible for recognizing sign language. This first stage, allowed the increase of interaction and the construction of an algorithm capable of accurately recognizing sign language. On a second stage of the validation, the proposal was studied so that the pros and cons can be determined and considered on future works.

Designing and implementing a performance measurement system in Auto Ribeiro, Lda.

In any business it is very important to measure the performance and it helps to select key information to make better decisions on time. This research focuses on the design and implementation of a performance measurement system in a Portuguese medium size firm operating in the specialized health care transformation vehicles industry. From the evidence that outputs from Auto Ribeiro’s current information system is misaligned with the company’s objectives and strategy, this research tries to solve this business problem through the development of a Balanced Scorecard analysis, although there are some issues, which deserve further development.

Perceptions of the usefulness of external support to immunization coverage in Guinea-Bissau: a Delphi analysis of the GAVI-Alliance cash-based support

INTRODUCTION: Although many countries have improved vaccination coverage in recent years, some, including Guinea-Bissau, failed to meet expected targets. This paper tries to understand the main barriers to better vaccination coverage in the context of the GAVI-Alliance (The Global Alliance for Vaccines and Immunisation) cash-based support provided to Guinea-Bissau. METHODS: The analysis is based on a document analysis and a three round Delphi study with a final consensus meeting. RESULTS: Consensus attributed about 25% of the failure to perform better to implementation problems; and about 10% to governance and also 10% to scarce resources. The qualitative analysis validates the importance of implementation issues and upgraded the relevance of the human resources crisis as an important drawback. The recommendations were balanced in their upstream-downstream focus but were blind to health information issues and logistical difficulties. CONCLUSIONS: It is commendable that such a fragile state, with all sorts of barriers, manages to sustain a slow steady growth of its vaccination coverage. Not reaching the targets set reflects the inappropriateness of those targets rather than a lack of commitment of the health workforce. In the unstable context of countries such as Guinea-Bissau, the predictability of the funds from global health initiatives like the GAVI-Alliance seem to make all the difference in achieving small consistent health gains even in the presence of other major bottlenecks.

Low cost carriers: The case of Oporto Airport and its touristic impact in the region

Both Oporto and the North Region of Portugal definitions of tourism have evolved significantly during the past decade. In this journey it is relevant to highlight the contribution of the arrival of Low Cost Carriers (LCCs) at Francisco Sá Carneiro Airport, thus contributing to a rapid expansion of this region as a tourism destination. Hence, this work project aims to understand the touristic and economic impact motivated by the entry of LCCs in Oporto and in the North Region of Portugal and tries to understand if this event was in fact an asset in the development of the aforementioned tourism destinations.

Portuguese stagnation in the 2001-2012 period

The 2001-2012 period has been one of very low growth for Portugal. This work project tries to find reasons for this slowdown. Growth in real GDP will be explained by several variables ranging from education, capital, government and world markets. Compensation of employees, capital per worker and the exports of competitors seem to explain a significant part of the slowdown. The ratio of non-tradables to tradables is also included but not significant, maybe due to a poor sample size. Stagnation then seems to be caused both by low growth in input accumulation and productivity as predicted by Amador and Coimbra in 2007.
