Avaliação do desempenho das políticas de gestão e proteção do litoral continental português

Esta dissertação teve como objectivo principal desenvolver indicadores que sejam ao mesmo tempo abrangentes e diferenciadores das especificidades locais existentes na orla costeira do continente português com base na informação de base disponível e assim evidenciar a importância desta abordagem no apoio à gestão integrada das zonas costeiras tal como preconizado pelas Recomendações Europeias sobre GIZC de 2002 (Recomendações 2002/413/CE, 2002). Em Portugal, é no litoral que se encontra a maior parte da sua população, assim como recursos e atividades económicas estratégicas para o interesse nacional, pelo que a disponibilização de dados, que permitam rápidas leituras em diversos domínios sobre o litoral, assumem aspectos de enorme importância em diversas vertentes que importam a um efetivo desenvolvimento que se deseja sustentável e que vão desde o apoio à gestão do ponto de vista técnico e administrativo, no suporte a decisões políticas e no apoio a sectores produtivos. Esta dissertação resulta de um estágio de 7 meses na Agência Portuguesa do Ambiente onde foi efectuado um tratamento da informação em ambiente SIG após uma recolha dos dados de base disponíveis que, embora não tenha sido exaustiva, abrange um conjunto de indicadores muito representativos da realidade costeira e que vai desde os tradicionais censos do INE de 2011 até à sua combinação com dados geográficos. O trabalho teve como ponto de partida o trabalho desenvolvido no âmbito do projeto europeu SUSTAIN, que é um projeto que pretendeu avaliar e promover políticas locais de sustentabilidade das zonas costeiras, mas onde os indicadores referentes à caracterização do risco costeiro dominaram face às recomendações resultantes do Grupo de Trabalho do Litoral criado ao abrigo do despacho n.º 6574/2014, de 20 de maio. A dissertação teve ainda como objetivo secundário a inserção dos indicadores em sistemas de informação baseados em informação geográfica de forma a poderem ter uma ampla divulgação, sendo exemplo a plataforma colaborativa SIARL - Sistema de Administração do Recurso Litoral, que possui um campo próprio para implementação de indicadores deste tipo (www.siarl.igeo.pt) e que tem como objetivo principal ser uma ferramenta de apoio à decisão e que facilite a troca de experiências e o acesso à informação institucional. A análise efetuada no âmbito desta dissertação vem em grande parte evidenciar as assimetrias já referenciadas por muitos especialistas que se debruçaram sobre estas matérias, designadamente em termos de usos do solo, de risco ou demográficos, permitindo definir rumos claros quanto à política de dados a desenvolver pelas entidades responsáveis pela sua produção tendo em vista obterem-se indicadores que visem favorecer a gestão integrada das zonas costeiras.

O âmbito de aplicação material da legislação de proteção de dados pessoais e o tratamento de imagem por pessoa singular

Images have gained a never before seen importance. Technological changes have given the Information Society extraordinary means to capture, treat and transmit images, wheter your own or those of others, with or without a commercial purpose, with no boundaries of time or country, without “any kind of eraser”. From the several different ways natural persons may engage in image processing with no commercial purpose, the cases of sharing pictures through social networks and video surveillance assume particular relevance. Consequently there are growing legitimate concerns with the protection of one's image, since its processing may sometimes generate situations of privacy invasion or put at risk other fundamental rights. With this in mind, the present thesis arises from the question: what are the existent legal instruments in Portuguese Law that enable citizens to protect themselves from the abusive usage of their own pictures, whether because that image have been captured by a smartphone or some video surveillance camera, whether because it was massively shared through a blog or some social network? There is no question the one's right to not having his or her image used in an abusive way is protected by the Portuguese constitution, through the article 26th CRP, as well as personally right, under the article 79th of the Civil Code, and finally through criminal law, articles 192nd and 193rd of the Criminal Code. The question arises in the personal data protection context, considering that one's picture, given certain conditions, is personal data. Both the Directive 95/46/CE dated from 1995 as well as the LPD from 1998 are applicable to the processing of personal data, but both exclude situations of natural persons doing so in the pursuit of activities strictly personal or family-related. These laws demand complex procedures to natural persons, such as the preemptive formal authorisation request to the Data Protection National Commission. Failing to do so a natural person may result in the application of fines as high as €2.500,00 or even criminal charges. Consequently, the present thesis aims to study if the image processing with no commercial purposes by a natural person in the context of social networks or through video surveillance belongs to the domain of the existent personal data protection law. To that effect, it was made general considerations regarding the concept of video surveillance, what is its regimen, in a way that it may be distinguishable from Steve Mann's definition of sousveillance, and what are the associated obligations in order to better understand the concept's essence. The application of the existent laws on personal data protection to images processing by natural persons has been analysed taking into account the Directive 95/46/CE, the LPD and the General Regulation. From this analysis it is concluded that the regimen from 1995 to 1998 is out of touch with reality creating an absence of legal shielding in the personal data protection law, a flaw that doesn't exist because compensated by the right to image as a right to personality, that anyway reveals the inability of the Portuguese legislator to face the new technological challenges. It is urgent to legislate. A contrary interpretation will evidence the unconstitutionality of several rules on the LPD due to the obligations natural persons are bound to that violate the right to the freedom of speech and information, which would be inadequate and disproportionate. Considering the recently approved General Regulation and in the case it becomes the final version, the use for natural person of video surveillance of private spaces, Google Glass (in public and private places) and other similar gadgets used to recreational purposes, as well as social networks are subject to its regulation only if the images are shared without limits or existing commercial purposes. Video surveillance of public spaces in all situations is subject to General Regulation provisions.

Cultural journalism in a digital environment : new models, practices and possibilities

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.

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.

Digital interconnectivity as a driver for port and logistics competitiveness

Creating an innovative tool that takes advantage of digital interconnectivity between shipping agencies and husbandry services suppliers was the starting point. But the main purpose of this paper is to figure out if that represents a business opportunity. It describes the preliminary stages undertaken, as the connections with the main potential providers of the husbandry services. This was carried out as a qualitative research, based on interviews given by shipping agencies that contributed as a source of data about their activities but also to survey their acceptance of the concept that could change the way of doing business in this area.At the same time, inquiries have been made to build financial scenarios that show the costs and revenue streams allocated to this project. Considering the data collected from the main players in husbandry services and the different outcomes, the feasibility of this project is assessed. Even though the paradigm was well received by all the firms contacted, the development costs turn out to be the main threat to the project so further steps are advised.

Gd2O3: Eu3+/PPO/POPOP/PS composites for digital imaging radiation detectors

Polymer based scintillator composites have been produced by combining polystyrene (PS) and Gd2O3:Eu3+ scintillator nanoparticles. Polystyrene has been used since it is a flexible and stable binder matrix, resistant to thermal and light deterioration and with suitable optical properties. Gd2O3:Eu3+ has been selected as scintillator material due to its wide band gap, high density and visible light yield. The optical, thermal and electrical characteristics of the composites were studied as a function of filler content, together with their performance as scintillator material. Additionally 1wt.% of 2,5 dipheniloxazol (PPO) and 0.01wt.% of (1,4-bis(2-(5-phenioxazolil))-benzol (POPOP) were introduced in the polymer matrix in order to strongly improve light yield, i.e. the measured intensity of the output visible radiation, under X-ray irradiation. Whereas increasing scintillator filler concentration (from 0.25wt.% to 7.5wt.%) increases scintillator light yield, decreases the optical transparency of the composite. The addition of PPO and POPOP, strongly increased the overall 2 transduction performance of the composite due to specific absorption and re-emission processes. It is thus shown that Gd2O3:Eu3+/PPO/POPOP/PS composites in 0.25 wt.% of scintillator content with fluorescence molecules is suitable for the development of innovate large area X-ray radiation detectors with huge demand from the industries.

Effect of the acoustic impedance in ultrasonic emitter transducers using digital modulations

In an underwater environment it is difficult to implement solutions for wireless communications. The existing technologies using electromagnetic waves or lasers are not very efficient due to the large attenuation in the aquatic environment. Ultrasound reveals a lower attenuation, and thus has been used in underwater long-distance communications. The much slower speed of acoustic propagation in water (about 1500 m/s) compared with that of electromagnetic and optical waves, is another limiting factor for efficient communication and networking. For high data-rates and real-time applications it is necessary to use frequencies in the MHz range, allowing communication distances of hundreds of meters with a delay of milliseconds. To achieve this goal, it is necessary to develop ultrasound transducers able to work at high frequencies and wideband, with suitable responses to digital modulations. This work shows how the acoustic impedance influences the performance of an ultrasonic emitter transducer when digital modulations are used and operating at frequencies between 100 kHz and 1 MHz. The study includes a Finite Element Method (FEM) and a MATLAB/Simulink simulation with an experimental validation to evaluate two types of piezoelectric materials: one based on ceramics (high acoustic impedance) with a resonance design and the other based in polymer (low acoustic impedance) designed to optimize the performance when digital modulations are used. The transducers performance for Binary Amplitude Shift Keying (BASK), On-Off Keying (OOK), Binary Phase Shift Keying (BPSK) and Binary Frequency Shift Keying (BFSK) modulations with a 1 MHz carrier at 125 kbps baud rate are compared.
