Relating the spatial component and users interests to improve applications based on questions, petitions and participatory processes

Nowadays, participatory processes attending the need for real democracy and transparency in governments and collectives are more needed than ever. Immediate participation through channels like social networks enable people to give their opinion and become pro-active citizens, seeking applications to interact with each other. The application described in this dissertation is a hybrid channel of communication of questions, petitions and participatory processes based on Public Participation Geographic Information System (PPGIS), Participation Geographic Information System (PGIS) and ‘soft’ (subjective data) Geographic Information System (SoftGIS) methodologies. To achieve a new approach to an application, its entire design is focused on the spatial component related with user interests. The spatial component is treated as main feature of the system to develop all others depending on it, enabling new features never seen before in social actions (questions, petitions and participatory processes). Results prove that it is possible to develop a working application mainly using open source software, with the possibility of spatial and subject filtering, visualizing and free download of actions within application. The resulting application empowers society by releasing soft data and defines a new breaking approach, unseen so far.

Breaking the Pattern and Creating New Paths – Feminist Mizrahi Women Artists in Israel

This article addresses the work of Mizrahi women artists, i.e., Israeli-Jewish women of Asian or African ethnic origin, using the artist Vered Nissim as a case study. Nissim seeks to affirm the politics of identity and recognition, as well as feminism in order to create a paradigm shift with regards to the local regime of cultural representations in the Israeli art scene. Endeavouring to find ways of undermining the rigid imbalances between different social groups, she calls for a comprehensive reform of the status quo through artistic activism. Nissim employs a style, content, and medium that disrupts the accepted social order, using humour and irony as unique weapons with which she takes liberties with conventional moral, social, and economic values. Placing issues of race, class and gender at the centre of her work, she seeks to undermine and problematize essentialist attitudes, highlighting the political intersections of different identity categories as the critical analysis of intersectionality unfolds.

Análise configuracional dos grandes conjuntos urbanos na Região de Lisboa (1945-1974) : contributos da sintaxe espacial para a história de arte como história da cidade

A presente investigação debruça-se sobre o estudo dos grandes conjuntos urbanos, tendo como referência a área de Lisboa no período entre 1945 e 1974. O seu objetivo principal é compreender o padrão espacial e respetivas variantes destas formas urbanas relativamente recentes bem como avaliar o seu impato na estrutura global da cidade e da sociedade. Tomando como ponto de partida a história de arte como história da cidade, a tese toma como objeto o grande conjunto urbano e aponta a hipótese do estudo da relação forma-fundo como meio de obter informações relevantes que relacionem o uso e função com respeito ao desenho do espaço aberto. Como diferentes arranjos entre espaços abertos e fechados implicam tipos espaciais distintos (Medeiros 2013), o estudo da relação entre a forma (cheio) e o fundo (vazio) dos grandes conjuntos urbanos e respetivas variações, pode fornecer-nos informação espacial relevante, que nos permitem compreender melhor estas formas urbanas recentes. Usando a abordagem própria da teoria da sintaxe espacial (Hillier e Hanson 1984), do tipo configuracional, determinam-se as relações entre os vários elementos constituintes dos sistemas espaciais formados nestas urbanizações. Essas relações são depois analisadas através de medidas e variáveis topológicas que nos permitem identificar qualidades e valores espaciais para a sociedade. Os resultados obtidos a partir dessas variáveis e medidas permitem-nos, depois, avaliar os graus de ‘formalidade’ e ‘urbanidade’ em cada sistema (Holanda 2002). Consequentemente, a avaliação qualitativa das características espaciais que se pretendem obter nesta investigação, tem como base a avaliação quantitativa, permitindo assim comparar mais facilmente os diversos casos de estudo. De entre o conjunto de casos analisados, o estudo revela uma série de características comuns, que nos permitem identificar um padrão específico de urbanismo modernista que reflete claramente um conjunto de ideologias associadas a uma visão reformista da sociedade através do espaço. Mas por outro lado, existem também um conjunto de características particulares de cada caso, que reportam para a estrutura morfológica da cidade tradicional. No que reporta à hipótese de estudo levantada nesta investigação sobre a relação forma-fundo, verifica-se através da amostra que esta relação aparece invertida. Esta diferenciação deve-se ao abandono dos tradicionais sistemas de rua e de quarteirão, ainda presentes nas urbanizações de Alvalade e do Areeiro e a sua substituição pelo bloco livre em espaço aberto como nos casos de Alfragide, Portela e Olivais. Tal facto, como prova a teoria da Sintaxe Espacial ou Lógica Social do Espaço, traduziu-se necessariamente em diferentes modos de vida pública e privada e consequentemente de vida espacial e social. Assim concluímos, através da análise dos casos de estudo apresentados, que embora fazendo parte duma mesma ideologia urbana com características comuns (genótipo modernista), os mesmos apresentam resultados espaciais totalmente diferenciados o que justifica a dificuldade da sua análise comparativa.

Land cover mapping analysis and urban growth modeling using remote sensing techniques

The rapid growth of big cities has been noticed since 1950s when the majority of world population turned to live in urban areas rather than villages, seeking better job opportunities and higher quality of services and lifestyle circumstances. This demographic transition from rural to urban is expected to have a continuous increase. Governments, especially in less developed countries, are going to face more challenges in different sectors, raising the essence of understanding the spatial pattern of the growth for an effective urban planning. The study aimed to detect, analyse and model the urban growth in Greater Cairo Region (GCR) as one of the fast growing mega cities in the world using remote sensing data. Knowing the current and estimated urbanization situation in GCR will help decision makers in Egypt to adjust their plans and develop new ones. These plans should focus on resources reallocation to overcome the problems arising in the future and to achieve a sustainable development of urban areas, especially after the high percentage of illegal settlements which took place in the last decades. The study focused on a period of 30 years; from 1984 to 2014, and the major transitions to urban were modelled to predict the future scenarios in 2025. Three satellite images of different time stamps (1984, 2003 and 2014) were classified using Support Vector Machines (SVM) classifier, then the land cover changes were detected by applying a high level mapping technique. Later the results were analyzed for higher accurate estimations of the urban growth in the future in 2025 using Land Change Modeler (LCM) embedded in IDRISI software. Moreover, the spatial and temporal urban growth patterns were analyzed using statistical metrics developed in FRAGSTATS software. The study resulted in an overall classification accuracy of 96%, 97.3% and 96.3% for 1984, 2003 and 2014’s map, respectively. Between 1984 and 2003, 19 179 hectares of vegetation and 21 417 hectares of desert changed to urban, while from 2003 to 2014, the transitions to urban from both land cover classes were found to be 16 486 and 31 045 hectares, respectively. The model results indicated that 14% of the vegetation and 4% of the desert in 2014 will turn into urban in 2025, representing 16 512 and 24 687 hectares, respectively.

Exporting a model of integrated disease management: A cross-case study analysis and application to Associação Protectora dos Diabéticos de Portugal

Although literature is lacking in the topic of internationalization of services, we manage to apply both the Uppsala model and the Eclectic Theory to the healthcare service. A cross-case study analysis with three international hospitals is done in order to define an internationalization pattern and conditions for a successful process. This is then applied to Associação Protectora dos Diabéticos de Portugal with the purpose of defining an internationalization strategy to the Association.
