A influência das audiências no jornalismo online: o caso do “Observador”

O presente relatório de estágio tem por base o estágio curricular com duração de três meses (Setembro de 2014 a Dezembro de 2014) realizado na redação do jornal online Observador. A rápida evolução da internet tem proporcionado avanços significativos em várias áreas e o jornalismo é uma delas. O jornalismo tem agora novas funcionalidades online, novas ferramentas e novos públicos. Assim, importa discutir as problemáticas editoriais deste tipo de publicação e perceber qual o tipo de artigo que é mais popular e se existe um desvio editorial para corresponder aos desejos do público, de modo a aumentar o número de leitores. Este relatório, além de pretender compreender o peso e os efeitos das audiências nas escolhas editoriais dos jornais online, em específico, do jornal Observador, descreve também a experiência pessoal do estágio aqui realizado, onde se tenta perceber como funciona a redação.

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.

As apostas desportivas online associadas à combinação de resultados

The present dissertation is aimed at finding out whether the existing criminal protection of the sports ethics value is sufficient, regarding the dangers arising from the global online sports betting market and its characteristics. In the first chapter, the main issue will be introduced: the association between online sports bets and competition manipulations from a criminal point of view. In the second chapter, online sports bets will be defined, the characteristics of the referred global market explained and the danger said features bear to the manipulation of sports competitions exposed – also analysing the participants in this phenomenon. In chapter 3, it will be shown that the protection of sports ethics is a matter of public interest and that this interest is carried out by the sports federations as well. In the fourth chapter, the focus will be the criminal protection of sports ethics: its necessity based on the penal dignity of this system of sport associated values; the need to re-evaluate the existing protection due to the recognition of the existence of the online sports betting market; the existing criminal norms regarding the manipulation of sports competitions. Finally, in chapter 5, the intent will be to propose solutions to the identified problems concerning the sufficiency of the existing criminal legislation.

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.

Marketing plan for online aqctivity of Rota Vicentina boosting direct website sales

The nature tourism experienced a great expansion of its market with the appearance of different lifestyles. In this Work Project a study regarding the website direct sales of Rota Vicentina was developed. Its website shows the idea of being solely an information structure and not a purchase one, leading to a current absence of online sales. Hence, it is suggested the modification of its business model, using different instruments and channels. Some digital marketing recommendations were developed in order to boost website sales, such as a platform for online reviews, remarketing campaigns and social media activity.

Exploring the consumer decision journey and online shoping experience through an emotional prespective

Traditional consumer decision-making models have long used quantitative research to address a link between emotional and rational behavior. However, little qualitative research has been conducted in the area of online shopping as an end-to-end experience. This study aims to provide a detailed phenomenological account of consumers’ online shopping experience and extend Mckinsey & Companys’s consumer decision journey model from an emotional perspective. Six semi-structured interviews and a focus group of nine people are analyzed using Interpretive Phenomenology Analysis and five superordinate themes emerged from the results: emotional experience, empathy and encouragement, in relation to brand preference, emotional encounters in relation to consumer satisfaction and emotional exchange and relationship with a company or brand. A model interrelating these themes is then introduced to visually represent the emotional essence of a large online purchase. This study promises to be applicable as a descriptive, and perhaps, better predictive report for understanding the complex consumer decision-making process as it relates to online consumer behavior. Future research topics are also identified.

Online strategies for offline business the case of Millennials and shopping centrs (Sonae Sierra)

The project, conducted within a direct research internship at Sonae Sierra, aims to propose innovative digital approaches for Shopping Centres (SC) to deal successfully with millennial consumer behavior concerning digital devices and online content in relation to shopping. An online survey followed by a focus group were conducted for this purpose. Results show a demand for specific digital services created by a SC and that their perception depends highly on gender of millennials. Moreover it´s a cohort seeking for personalized content, providing emotional or functional benefit. Consequently a SC must deliver services, as presented in this work satisfying those needs.
