RESULTS: Participants with higher levels of education were more likely to identify correctly the vector of the disease. CONCLUSIONS: The results emphasize the relevance of health education programs, the continuous promotion of educational campaigns in the media, the role of the television as a source of information, and the importance of motivating the population to control the vector.

AS COSTUREIRAS, AS QUEENS E OS SEUS MANTOS: DESTERRITORIALIZAÇÃO, CULTURA MATERIAL E CONSTRUÇÃO DO LUGAR

Durante as décadas de 1980 e de 1990 a noção de lugar foi, na literatura antropológica, sujeita a uma abordagem crítica que debateu as dimensões metodológicas e conceptuais envolvidas na sua construção. No seguimento dessa abordagem, surgiram propostas de trabalho que, de maneiras muito diversas, conseguiram ultrapassar as limitações das concepções mais clássicas da figura do lugar. Essas propostas revelaram, no entanto, que mesmo quando estamos face a uma lógica de desterritorialização, a figura do lugar pode reaparecer (embora obviamente transmutada, visto construir-se no interior de outras lógicas sociais, culturais e económicas). Partindo de uma etnografia realizada na Ilha do Pico, o texto explora algumas das inovações, provenientes dos EUA no início do século XX, que foram introduzidas nas Festas do Espírito Santo. A principal inovação prende-se com a emergência de novos personagens: as rainhas (“queens”) coroadas durante o ritual, seguidas pelas costureiras indispensáveis à confecção dos seus vestidos e mantos. Centrado nos processos de feitura dos mantos, o texto pretende mostrar como a cultura material local se constrói e se transforma no interior de um movimento transcontinental constante de pessoas, rituais, coisas e técnicas. Num contexto transnacional, a mobilidade das pessoas pode objetificar-se em coisas que são feitas localmente, participando assim a desterritorialização na construção do lugar.

Geopolymers as infill material for conservation of azulejos

The restoration materials currently used to fill gaps in architectural historical azulejos (e.g. lime or organic resin pastes) usually show serious drawbacks in terms of compatibility, effectiveness and durability. The existing solutions do not fully protect azulejos in outdoor conditions and frequently result in further deterioration. Geopolymers can be a potential solution for azulejo lacunae infill given the chemical-mineralogical similitude to the ceramic body, and also the durability and versatile range of physical properties that can be obtained through the manipulation of their formulation and curing conditions. This work presents and discusses the viability of the use of geopolymeric pastes to fill lacunae in azulejos or to act as “cold” cast ceramic tile surrogates reproducing missing azulejo fragments. The formulation of geopolymers, namely the type of activators, the aluminosilicate source, the amount of water (to meet adequate workability requirements) and curing conditions were studied. The need for post-curing desalination was also considered envisaging their application in the restoration of outdoor architectural historical azulejos frequently exposed to adverse environmental conditions. The possible advantages and disadvantages of the use of geopolymers in the conservation of azulejos are also discussed. Several techniques were used to study the chemical and physical behavior of geopolymers, namely FT-IR, XRD, MIP, SEM-EDS, WDXRF, electrical conductivity, open porosity, bending strength, adhesion strength, water vapour permeability, thermal expansion and hydric expansion. The results indicate that geopolymers are a promising material for restoration of azulejos, exhibiting some properties, such as adhesion to the ceramic substrate, higher than inorganic materials used nowadays, such as aerial lime based pastes.

Al-doped ZnO ceramic sputtering targets based on nanocrystalline powders produced by emulsion detonation synthesis – deposition and application as a transparent conductive oxide material

Transparent conducting oxides (TCOs) have been largely used in the optoelectronic industry due to their singular combination of low electrical resistivity and high optical transmittance. They are usually deposited by magnetron sputtering systems being applied in several devices, specifically thin film solar cells (TFSCs). Sputtering targets are crucial components of the sputtering process, with many of the sputtered films properties dependent on the targets characteristics. The present thesis focuses on the development of high quality conductive Al-doped ZnO (AZO) ceramic sputtering targets based on nanostructured powders produced by emulsion detonation synthesis method (EDSM), and their application as a TCO. In this sense, the influence of several processing parameters was investigated from the targets raw-materials synthesis to the application of sputtered films in optoelectronic devices. The optimized manufactured AZO targets present a final density above 99 % with controlled grain size, an homogeneous microstructure with a well dispersed ZnAl2O4 spinel phase, and electrical resistivities of ~4 × 10-4 Ωcm independently on the Al-doping level among 0.5 and 2.0 wt. % Al2O3. Sintering conditions proved to have a great influence on the properties of the targets and their performance as a sputtering target. It was demonstrated that both deposition process and final properties of the films are related with the targets characteristics, which in turn depends on the initial powder properties. In parallel, the influence of several deposition parameters in the film´s properties sputtered from these targets was investigated. The sputtered AZO TCOs showed electrical properties at room temperature that are superior to simple oxides and comparable to a reference TCO – indium tin oxide (ITO), namely low electrical resistivity of 5.45 × 10-4 Ωcm, high carrier mobility (29.4 cm2V-1s-1), and high charge carrier concentration (3.97 × 1020 cm-3), and also average transmittance in the visible region > 80 %. These superior properties allowed their successful application in different optoelectronic devices.

Torrefação de biomassa de Arundo donax L. e de Phoenix canariensis com vista à sua valorização energética ou material

A torrefação é vista como um pré-tratamento térmico que introduz modificações na biomassa, ou em resíduos de biomassa, que facilitam o seu processamento mecânico e aumentam a sua estabilidade e densidade energética, potenciando, assim, uma valorização posterior. Neste trabalho, estudou-se o impacte da torrefação na gama de 200 a 350 ºC e tempos de residência entre 15 e 90 min nas propriedades da biomassa proveniente da herbácea Arundo donax L. e das palmeiras Phoenix canariensis, espécies muito abundantes em vários locais do país, tendo em vista a sua posterior valorização. A proliferação descontrolada do arundo e a praga do escaravelho das palmeiras leva a que estas espécies sejam alvo de frequentes operações de remoção. A sua estrutura altamente fibrosa dificulta e encarece estas operações, que acarretam custos significativos para as câmaras municipais, e não se conhecem medidas para a sua valorização material ou energética. A torrefação foi também aplicada a peletes de resíduos de pinheiro, na gama de 200 a 250 ºC e com tempos de residência de 30 e 60 min, para averiguar o seu impacte na qualidade desse biocombustível sólido. A torrefação permitiu obter peletes mais resistentes à biodegradação, devido à redução do teor de humidade para valores residuais, sem aumentar significativamente o seu teor de cinzas e sem afetar de forma relevante a sua durabilidade, o teor de finos ou a densidade aparente. Com a biomassa de arundo e de palmeira obtiveram-se produtos com maior poder calorífico e com melhor moabilidade. No entanto, a acentuada diminuição dos rendimentos mássico e energético e o elevado teor de cinzas constrangem a sua utilização como biocombustíveis sólidos. Desta forma, optou-se por testar a sua valorização como adsorventes do corante azul de metileno, bastante comum, por exemplo, na indústria têxtil, nos curtumes ou nas industrias do papel. Os estudos de adsorção revelaram maior afinidade pelo corante por parte da biomassa sujeita a torrefação mais ligeira, com eficiências de remoção muito próximas das do carvão ativado comercial, para concentrações iniciais de corante até 200 mg/L. As isotérmicas foram melhor ajustadas ao modelo de Langmuir, que revelou capacidades máximas de adsorção na monocamada entre 59,92 e 92,68 mg/g, tendo as curvas de cinética sido melhor descritas pelo modelo de pseudo-segunda ordem. A adsorção é bastante rápida nos primeiros minutos, essencialmente devido a atrações eletrostáticas, sendo inicialmente controlada pela difusão no filme e depois pela difusão nos poros. Os adsorventes revelaram seletividade por um corante catiónico e permitiram dessorção de corante, ao contrário do verificado com o carvão ativado comercial, o que é um aspeto da maior relevância tendo em mente a regeneração do adsorvente e a recuperação do corante.

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.

An essay on agile project management practices

The main goals for the current dissertation is to research on how practices and concepts from Agile Project Management can be applied in a non-IT context and to discover which aspects should be considered when deciding if whether an Agile approach should be implemented or not. Previous studies reflect on the adoption for the identified context. However, the recognition of these practices and concepts by the Project Management field of studies still remains unresolved. The adoption of Agile Project Management emerges as a manifestation against traditional approaches, mainly due to their inability of accepting requirements’ changes. Therefore, these practices and concepts can be considered in order to reduce the risks concerning the increase of competition and innovation – which does not apply to the IT sector solely. The current study reviews the literature on Agile Project Management and its adoption across different sectors in order to assess which practices and concepts can be applied on a non-IT context. Nine different methods are reviewed, where two of these show a higher relevance – Scrum and Extreme Programming. The identified practices and concepts can be separated into four different groups: Cultural and Organizational Structures, Process, Practices, and Artefacts. A framework based on the work by Boehm & Turner in 2004 is developed in order to support the decision of adopting agile methods. A survey intended for project managers was carried in order to assess the implementation of the identified practices and concepts and to evaluate which variables have the highest importance on the developed decision support framework. It is concluded that New Product Development is the project type with the highest potential to implement an agile approach and that the Project Final Product’s Innovativeness, Competitiveness, and the Project Member’s Experience and Autonomy are the most important aspects to consider an implementation of an Agile approach.

Performance management practices in Portugal.

Performance management and assessment has returned to the forefront of the public debate in Portugal, at the same time that some international studies point Portugal as a country with bad management practices, highlighting performance management practices. Despite all this attention, there is little information about how those practices are applied in the country. This research’s goal is to assess why performance management systems and practices are so poorly applied in Portugal. To achieve this goal we studied employees’ perception about the topic and diagnose the associated problems. The methodology comprised inductive and qualitative research, in the form of interviews with employees from different professions, industries, hierarchies, and ages. Our findings suggest that performance management failure is related with a procedural problem with three different dimensions: Insufficient Planning, Process & Integrity Issues, and Non-Meritocratic Logic. By exposing the different components of the Portuguese performance management problem, we shed light into the topic and allow organizations to understand and face their performance management systems’ flaws.

An analysis of associations between human resources practices, affective commitment, exhaustion and cynicism of temportary workers

This research examines the relationships between Human Resources Practices (HRP) and affective commitment, exhaustion, and cynicism of temporary workers. Furthermore, voluntariness and tenure with the client organization are assumed in the analysis as moderators. A sample of Temporary Agency workers was surveyed. It was assumed that HRP positively relates with affective commitment, while negatively with exhaustion and cynicism. Results confirmed the proposed relationships. Regarding the moderators, it has been proved that voluntariness partially weakens the relationships between HRP and temporary workers’ outcomes. However, contrary to the hypothesis, this effect cannot be affirmed also for the tenure with the client organization. Previous literature as well as implications of the findings are discussed.
