Esta dissertação pretende analisar as práticas de dois artistas contemporâneos, Ryan Trecartin e Jacolby Satterwhite, nomeadamente a nível do modo como trabalham a intersecção do vídeo digital e da performance como forma de manifestação de corporalizações queer através do corpo masculino. Mais concretamente, interessa-nos focar processos de “queerificação” e de produção de corpos que emergem intrinsecamente pelo médium digital, e que exploram as possibilidades transformativas do médium tanto a nível de representação, criação e mutação de formas, como a nível comunicacional e de possibilidades de subjectivação e corporalizações múltiplas. Para tal, partimos dos dois campos teóricos que se mostraram mais pertinentes relativamente aos processos artísticos em análise, nomeadamente: a teoria queer pelo modo como definiu o carácter performativo das normas de género e as categorizações identitárias sexuais como suporte da heteronormatividade, identificando estratégias para a sua re-significação; e o pensamento sobre a relação do corpo com o médium digital, pelo modo como delineou processos de corporalização através da tecnologia digital. A análise dos processos artísticos de Ryan Trecartin e Jacolby Satterwhite demonstra como a arte contemporânea é um território fértil não apenas para a exposição de matrizes normativas de opressão, mas também para a criação de mundos radicalmente queer em que, fazendo uso do potencial transformativo do médium digital, se manifestam realidades e corpos onde a normatividade é totalmente implodida.

This article argues that the study of literary representations of landscapes can be aided and enriched by the application of digital geographic technologies. As an example, the article focuses on the methods and preliminary findings of LITESCAPE.PT—Atlas of Literary Landscapes of Mainland Portugal, an on-going project that aims to study literary representations of mainland Portugal and to explore their connections with social and environmental realities both in the past and in the present. LITESCAPE.PT integrates traditional reading practices and ‘distant reading’ approaches, along with collaborative work, relational databases, and geographic information systems (GIS) in order to classify and analyse excerpts from 350 works of Portuguese literature according to a set of ecological, socioeconomic, temporal and cultural themes. As we argue herein this combination of qualitative and quantitative methods—itself a response to the difficulty of obtaining external funding—can lead to (a) increased productivity, (b) the pursuit of new research goals, and (c) the creation of new knowledge about natural and cultural history. As proof of concept, the article presents two initial outcomes of the LITESCAPE.PT project: a case study documenting the evolving literary geography of Lisbon and a case study exploring the representation of wolves in Portuguese literature.

In the following text I will develop three major aspects. The first is to draw attention to those who seem to have been the disciplinary fields where, despite everything, the Digital Humanities (in the broad perspective as will be regarded here) have asserted themselves in a more comprehensive manner. I think it is here that I run into greater risks, not only for what I have mentioned above, but certainly because a significant part, perhaps, of the achievements and of the researchers might have escaped the look that I sought to cast upon the past few decades, always influenced by my own experience and the work carried out in the field of History. But this can be considered as a work in progress and it is open to criticism and suggestions. A second point to note is that emphasis will be given to the main lines of development in the relationship between historical research and digital methodologies, resources and tools. Finally, I will try to make a brief analysis of what has been the Digital Humanities discourse appropriation in recent years, with very debatable data and methods for sure, because studies are still scarce and little systematic information is available that would allow to go beyond an introductory reflection.

A revista de bordo é um produto editorial bem conhecido do passageiro aéreo. Ela faz parte do universo da aviação há várias décadas, servindo tanto o propósito de distrair os passageiros com medo de voar, como o de veicular artigos de viagem de qualidade a amantes deste tipo de narrativa. Mas a crise financeira de 2008 e o aumento do preço do petróleo começaram a mudar a maneira como os gestores das companhias aéreas olham para este produto tão familiar aos passageiros. O novo século traz novos desafios e põe em causa a continuação deste tipo de publicação, pelo custo que representa para as companhias e para o meio ambiente. Mas a evolução da tecnologia e a crise que o próprio jornalismo atravessa na transição para o online podem conter a chave para este problema. Uma publicação de bordo nativa digital pode oferecer potencialidades únicas aos passageiros, ao mesmo tempo que lidera o caminho da inovação jornalística.

A onda de protestos globais de 2011 reacendeu o debate sobre as potencialidades e limitações que derivam da incorporação de novas tecnologias de informação e comunicação (TIC) por parte dos movimentos sociais. Que características diferenciam os movimentos sociais tradicionais dos contemporâneos? Quais os efeitos transformativos da apropriação das novas tecnologias por parte dos grupos de ação coletiva? De que modo as tecnologias digitais podem contribuir para o engajamento cívico e político? Esta dissertação pretende refletir sobre estas questões, através da análise de distintos casos de estudo onde que se incluem os mais mediáticos movimentos sociais dos últimos anos: a revolução tunisina e egípcia enquanto exemplos ilustrativos da “Primavera Árabe”; o caso islandês, onde as manifestações culminaram num inovador projeto de e-democracy; e o movimento espanhol 15M/Indignados, que mobilizou milhares de pessoas em prol de uma renovação do sistema democrático.

Many municipal activities require updated large-scale maps that include both topographic and thematic information. For this purpose, the efficient use of very high spatial resolution (VHR) satellite imagery suggests the development of approaches that enable a timely discrimination, counting and delineation of urban elements according to legal technical specifications and quality standards. Therefore, the nature of this data source and expanding range of applications calls for objective methods and quantitative metrics to assess the quality of the extracted information which go beyond traditional thematic accuracy alone. The present work concerns the development and testing of a new approach for using technical mapping standards in the quality assessment of buildings automatically extracted from VHR satellite imagery. Feature extraction software was employed to map buildings present in a pansharpened QuickBird image of Lisbon. Quality assessment was exhaustive and involved comparisons of extracted features against a reference data set, introducing cartographic constraints from scales 1:1000, 1:5000, and 1:10,000. The spatial data quality elements subject to evaluation were: thematic (attribute) accuracy, completeness, and geometric quality assessed based on planimetric deviation from the reference map. Tests were developed and metrics analyzed considering thresholds and standards for the large mapping scales most frequently used by municipalities. Results show that values for completeness varied with mapping scales and were only slightly superior for scale 1:10,000. Concerning the geometric quality, a large percentage of extracted features met the strict topographic standards of planimetric deviation for scale 1:10,000, while no buildings were compliant with the specification for scale 1:1000.

Both culture coverage and digital journalism are contemporary phenomena that have undergone several transformations within a short period of time. Whenever the media enters a period of uncertainty such as the present one, there is an attempt to innovate in order to seek sustainability, skip the crisis or find a new public. This indicates that there are new trends to be understood and explored, i.e., how are media innovating in a digital environment? Not only does the professional debate about the future of journalism justify the need to explore the issue, but so do the academic approaches to cultural journalism. However, none of the studies so far have considered innovation as a motto or driver and tried to explain how the media are covering culture, achieving sustainability and engaging with the readers in a digital environment. This research examines how European media which specialize in culture or have an important cultural section are innovating in a digital environment. Specifically, we see how these innovation strategies are being taken in relation to the approach to culture and dominant cultural areas, editorial models, the use of digital tools for telling stories, overall brand positioning and extensions, engagement with the public and business models. We conducted a mixed methods study combining case studies of four media projects, which integrates qualitative web features and content analysis, with quantitative web content analysis. Two major general-interest journalistic brands which started as physical newspapers – The Guardian (London, UK) and Público (Lisbon, Portugal) – a magazine specialized in international affairs, culture and design – Monocle (London, UK) – and a native digital media project that was launched by a cultural organization – Notodo, by La Fábrica – were the four case studies chosen. Findings suggest, on one hand, that we are witnessing a paradigm shift in culture coverage in a digital environment, challenging traditional boundaries related to cultural themes and scope, angles, genres, content format and delivery, engagement and business models. Innovation in the four case studies lies especially along the product dimensions (format and content), brand positioning and process (business model and ways to engage with users). On the other hand, there are still perennial values that are crucial to innovation and sustainability, such as commitment to journalism, consistency (to the reader, to brand extensions and to the advertiser), intelligent differentiation and the capability of knowing what innovation means and how it can be applied, since this thesis also confirms that one formula doesn´t suit all. Changing minds, exceeding cultural inertia and optimizing the memory of the websites, looking at them as living, organic bodies, which continuously interact with the readers in many different ways, and not as a closed collection of articles, are still the main challenges for some media.

Current computer systems have evolved from featuring only a single processing unit and limited RAM, in the order of kilobytes or few megabytes, to include several multicore processors, o↵ering in the order of several tens of concurrent execution contexts, and have main memory in the order of several tens to hundreds of gigabytes. This allows to keep all data of many applications in the main memory, leading to the development of inmemory databases. Compared to disk-backed databases, in-memory databases (IMDBs) are expected to provide better performance by incurring in less I/O overhead. In this dissertation, we present a scalability study of two general purpose IMDBs on multicore systems. The results show that current general purpose IMDBs do not scale on multicores, due to contention among threads running concurrent transactions. In this work, we explore di↵erent direction to overcome the scalability issues of IMDBs in multicores, while enforcing strong isolation semantics. First, we present a solution that requires no modification to either database systems or to the applications, called MacroDB. MacroDB replicates the database among several engines, using a master-slave replication scheme, where update transactions execute on the master, while read-only transactions execute on slaves. This reduces contention, allowing MacroDB to o↵er scalable performance under read-only workloads, while updateintensive workloads su↵er from performance loss, when compared to the standalone engine. Second, we delve into the database engine and identify the concurrency control mechanism used by the storage sub-component as a scalability bottleneck. We then propose a new locking scheme that allows the removal of such mechanisms from the storage sub-component. This modification o↵ers performance improvement under all workloads, when compared to the standalone engine, while scalability is limited to read-only workloads. Next we addressed the scalability limitations for update-intensive workloads, and propose the reduction of locking granularity from the table level to the attribute level. This further improved performance for intensive and moderate update workloads, at a slight cost for read-only workloads. Scalability is limited to intensive-read and read-only workloads. Finally, we investigate the impact applications have on the performance of database systems, by studying how operation order inside transactions influences the database performance. We then propose a Read before Write (RbW) interaction pattern, under which transaction perform all read operations before executing write operations. The RbW pattern allowed TPC-C to achieve scalable performance on our modified engine for all workloads. Additionally, the RbW pattern allowed our modified engine to achieve scalable performance on multicores, almost up to the total number of cores, while enforcing strong isolation.

Com o desenvolvimento das Tecnologias de Informação e Comunicação, as mesmas têm permitido dotar as pessoas de conhecimentos, através de formas mais rápidas e eficientes como é o caso da formação em e-learning. O número de organizações a apostar na formação em e-learning é cada vez maior, tornando-se importante perceber em que medida é que o método é eficaz e quais as vantagens que proporciona à organização, bem como o seu impacto no capital humano. Assim e visando averiguar como esta situação é vivenciada na prática decidiu-se pela realização de um estágio, na PT PRO pertencente Grupo Portugal Telecom. Para a construção deste relatório de estágio foi preciso para além da consulta e análise documental de aquivos internos e intranet, reuniões tidas com os elementos do departamento da Gestão de Formação, onde decorreu o estágio, visando dar uma resposta mais cabal à questão de partida que norteia o estágio: “Qual o impacto gerado pelas ações de e-learning, sua aplicabilidade e satisfação dos colaboradores face às mesmas na PT PRO?” O método utilizado neste estudo foi do tipo quantitativo, tendo sido aplicado um inquérito por questionário construído para o efeito. Face aos resultados obtidos, concluímos que na PT PRO, os colaboradores encontram-se globalmente satisfeitos com o conhecimento gerado e acima de tudo com a aplicabilidade do mesmo nas suas funções de trabalho.
