Abstract:

My minor dissertation in Intellectual Property Law is about Copyright Law and infringement in relation to mobile television, Internet Protocol Television and Internet Television as well as the online services of downloading and streaming. The thesis will contain of five chapters. The first chapter will give an overview of the nature of the problem, the structure and methodology as well as the named media and their technological background. The second chapter will then introduce the relevant technologies, institutions in charge and the general legislation and will serve as background information for the main issues of copyright. Further I will discuss operational licenses, which have to be distinguished from content licenses in the copyright correlation. Chapter three will be the focus of my thesis and will deal with copyright in connection with ITV, IPTV and mobile-TV. It will inter alia portray the issues of infringement, liability, exceptions and limitations in the named context as well as the proposed Copyright Amendment Bill 2015. The fourth chapter will then commence by discussing the German copyright in the relevant aspects of the topic. It will pay special attention to the legal dichotomy of online-streaming. Chapter five will summarise and conclude the relevant findings of the copyright issues. It will further give prospect to the legal dichotomy in South Africa and how to handle it, since there is no applicable local jurisdiction yet. Hence it will go beyond the comparisons by looking ahead for the developing online media and the necessity of law to properly adapt to it.

Abstract:

Western Kentucky University (WKU) offered a course entitled Biochemistry for the Health Sciences in the spring semester of 2007. The course was taught in Interactive Television (ITV) format, and was the first time a class had been taught in the format enabling two-way communication by the Chemistry Department. One section was present in an ITV broadcast classroom on the main campus in Bowling Green, Kentucky. Another section received the broadcast on the campus of Western Kentucky University-Owensboro (WKU-O), at Owensboro Community and Technical College (OCTC), located in Owensboro, Kentucky. The purpose of this thesis is to evaluate the delivery of the chemistry class and to ascertain if ITV is a suitable format for chemistry classes. Professor Larry Byrd taught the class in person to twenty-nine students in Bowling Green. David Martin, the author of this thesis, attended the class at WKU-0 along with one student, who was required to take the class for her Health Sciences major. The thesis addresses the technical aspects of an ITV class, the logistical challenges faced at both locations, the subject matter covered, and the reactions of students. A survey was administered to the Bowling Green class and the Owensboro student was interviewed. Suggestions for improvements were made for future classes. The conclusion is that ITV can certainly be used successfully for the delivery of chemistry classes. The student in Owensboro received an "A" for the semester. This result compared to 50% "A's", 32 % "B's", 9% "C's", and 9% "D's" and "W's" for the total class. The most needed improvement for the class is the inclusion of demonstrations of laboratory experiments on video. The technical and logistical challenges encountered can be overcome with more experience on the part of the professor and improvements in the courier transportation system. This particular class is scheduled to be offered via ITV in the fall 2007 semester and will be broadcast to multiple remote locations. This limited study of an ITV chemistry class shows that the delivery method is appropriate and reasonable. To broaden the statistical base for comparison of ITV classes to traditional classes, another series of experiments should be performed. A proposal for a study between a traditional class, an ITV main campus class, an ITV remote class, and a web-based class is included. This study is designed to compare student performance over a range of delivery methods for the same course.

Abstract:

This exploratory study was designed to examine counseling skill acquisition for Rehabilitation Counseling education students enrolled in a distance education Practicum I course. The course utilized interactive television (ITV), Desire 2 Learn (D2L), a course management system, and some formalized group meetings for curriculum delivery. Students were asked to provide two audio recordings that served as pre-test and post-test measures of counseling skills. Recordings were analyzed by two evaluators. In addition to the recordings, students completed two survey instruments, an initial demographic questionnaire and a survey of attitudes towards the use of technology in the course that was completed along with the post-test recording. A comparison of pre-test and post-test means on the audio recordings revealed no significant change in counseling skills for students enrolled in this course. There was an increase in the number of empathetic responses, clarifying statements, paraphrasing, questions and closing statements on the post-test recordings but a decrease in attending responses and opening statements. Survey findings indicated that students perceived distance education to be an effective use of their time and improved the quality of course interactions. Students also reported that technology made interacting with their peers difficult and somewhat impersonal. Approximately half of the students agreed that they were comfortable with the course technology. A majority to students indicated they would have preferred a traditional approach to learning counseling skills. These findings have implications for counseling programs currently utilizing ITV or webconferencing to deliver clinical skills courses. It may have broader implications for other clinical skills training programs delivering training via other distance education modalities.

Mestrado em Comunicação Multimédia
No contexto das alterações demográficas que se fazem sentir em Portugal com o crescente envelhecimento populacional, é essencial a preocupação em fornecer aos seniores ferramentas que contribuam para uma vida ativa e promovam a sua independência, numa sociedade em constante crescimento tecnológico. A presente investigação realiza-se no âmbito do projeto +TV4E, em desenvolvimento na Universidade de Aveiro, cujo objetivo é promover o envelhecimento ativo e contribuir para o bem-estar, qualidade de vida, infoinclusão e autonomia dos seniores. O projeto centra-se no objetivo de fazer chegar informação atualizada sobre serviços sociais e públicos às televisões dos seniores em suas casas, com vista a facilitar-lhes o acesso à informação. A ideia consiste em, durante a emissão atual da sua televisão, notificar o utilizador que surgiu uma nova informação pertinente acerca de um determinado assunto social ou público, pausar a transmissão normal, transmitir o breve vídeo informativo, e voltar à transmissão anterior no momento em que foi pausada, não havendo perda de conteúdo. O objetivo desta plataforma é minimizar as fragilidades relativas ao fluxo de informação e fazê-la chegar aos seniores sem falhas nem distorções da realidade. A investigação aqui apresentada surge no contexto deste projeto, e foca-se especificamente na componente audiovisual do projeto. Pretende identificar, do ponto de vista audiovisual, as principais características e linhas orientadoras para a construção de conteúdo informativo a transmitir através dos pequenos vídeos que surgirão, tendo em conta as necessidades do sénior. Para isto, foi construído um processo de criação e desenvolvimento de uma abordagem audiovisual, através da validação de elementos sonoros e visuais, com a colaboração de duas universidades seniores da região de Aveiro. Visto que o projeto +TV4E tem como público-alvo os seniores portugueses, foram convidados alunos da Universidade Sénior de Cacia e da Universidade Sénior da Curia a participar em sessões de design e contribuir com as suas opiniões para o ajuste de elementos sonoros, elementos textuais, iconografia e paleta de cores dos vídeos informativos a desenvolver.
In the context of the demographic changes in Portugal, especially the increasing of the ageing population, it becomes essential to worry about offering tools to seniors that can contribute to an active life and promote their independence within a society in a constant technological evolution. The present investigation is carried out in the scope of the +TV4E project, which is under development at University of Aveiro and it aims to promote active ageing and to contribute to seniors’ wellbeing, quality of life, info-inclusion and autonomy. This project focuses on bringing updated information about social and public services to the seniors’ home televisions, in order to facilitate their access to information. The idea consists in, during the linear television broadcast, notifying users about a new piece of information about a certain social or public matter, pausing the current emission, displaying a brief informative video spot and, finally, going back to linear television broadcasting where it was paused, avoiding content loss. This platform’s goal is to minimize informational flow’s fragilities and to bring accurate information to seniors without flaws and reality distortion. The present work fits into the +TV4E project by focusing specifically on its audio-visual component. It pretends to identify, in an audio-visual point of view, the main characteristics and design guidelines for videos with informative content, taking seniors’ needs into account. This led to a creation and development process in order to reach an adequate audio-visual approach, through the validation and definition of sound and visual elements, collaborating with two senior universities in Aveiro, Portugal. Since the Portuguese senior population is the project’s target audience, students from Senior University of Cacia and Senior University of Curia were invited to participate in design sessions and contribute with their opinions and inputs in order to adjust sound elements, text elements, iconography and colour pallet.

Abstract:

Le spectacle publicitaire télévisuel s'organise autour de trois grands axes, tout d'abord, il s'agit de faire un état des lieux qui permet de dégager les spécificités de la communication, du medium télévisuel, de faire ressortir les caractéristiques de toute stratégie publicitaire, de recenser les principaux actants de ce spectacle. Outre son aspect 'scientifique' qui apparaît notamment avec la complexité de la mesure d'audience, le spectacle publicitaire déploie, dans son processus de création, des qualités artistiques incontestables, valorisées lors de festivals. Une réflexion sur l'expression de la culture britannique dans les films publicitaires est indispensable; elle aide a mieux cerner les réalités et les préoccupations de cette société de 1988 a 1992
The study of television advertising has three main thrusts. It is first necessary to define the parameters which permit an investigation of communication in the televised medium, as well as analyse the techniques of advertising strategy and identify the principal participants and their roles, to this 'scientific' side of television advertising should be added the complexities of audience figures and the intricacies of rate cards. Advertising is, however, also a creative process in which artistic qualities can come to the fore and achieve recognition through a variety of competitions and festivals. Finally, advertising is the mirror of a society. This analysis of television commercials gives an insight into British life and culture, and particularly enables the researcher to identify the salient features and preoccupations of British society in the period 1988 to 1992

Abstract:

The study concerns the inter-relationship between media reform and civil society in Thailand between 1995-2000. It examines case studies of two selected television organisations - the production company Watchdog and the broadcast channel Independent Television (iTV) - and analyses their internal production decision-making processes, their public affairs programs and their urban and rural audiences. Debates about civil society and media reform between 1995-2000 influenced the government's media regulation policies to the extent that more attention was paid to media freedom as intended by Articles 39, 40 and 41 in the 1997 Constitution. Non-governmental Organisations (NGOs) took an important role in monitoring government policies on media reform under the Constitution and issues about media re-regulation and ownership were canvassed, although the drawn out National Broadcasting Commission (NBC) selecting process delayed media reform. The transparency of the selection process of the NBC has been widely debated among NGOs, media scholars and media professionals. Most Thai public affairs programs in the period were shown on iTV, Channel 9 and Channel 11 and were in the minority compared with entertainment. Thai television stations normally screened entertainment programs to make profits, while they usually would not allow producers to air open debates critical of the government. Also, public affairs programs that were screened often were given inappropriate airtimes. Watchdog and iTV treated public affairs programs in different ways. Watchdog, originating from an NCO, the Creative Media Foundation, emphasized public participation in local community-oriented programs - such as Chirmsak Pinthong's Lan Ban Lan Muang - which exemplified civic journalism on television. In contrast, iTV was created in 1996 to meet the promise made in 1992 after Black May that a non-state commercial channel would be introduced. It was organised by journalists from the Nation Multimedia Company and focused on current national news issues which seldom allowed public participation. Both organisations attempted to maintain their professionalism despite political and business pressures. Chirmsak and Watchdog were accused of bias favoring the Democrat Party and often encountered program censorship. ITV staff, especially in the news department led by Suthichai Yoon and Thepchai Yong, unsuccessful fought. Shin Corps 2000-2001 takeover of the station that had been brought on by the financial problems of iTV and the Siam Commercial Bank after the economic crisis of 1997. There were three main concepts of civil society in the period 1997-2000 - Communitarianism, Self-sufficiency and Good Governance. These ideas were advanced by reformers such as Dr. Prawase Wasi and Thirayut Boonme, and were reinforced by His Majesty King Bhumibol's December 1997 Birthday Speech that endorsed the ideal of national self-sufficiency. Thai civil society debates often were involved with rural people, while the 8th National Development Plan and the Chuan government's policy on decentralisation aimed to strengthen the rural sector as an antidote to the 1997 crisis. However, the aims of civil society reformers were at times too idealistic and were viewed with skepticism by some middle class urban critics. The continuing influence of electoral corruption in rural areas also obstructed civil society ideals, while decentralisation and community development still maintained a top-down way of development and depended on government support. These difficulties in implementing pro-civil society reforms in the political process were paralleled by difficulties in developing public interest programs on Thai television. Current affairs and investigative journalism programs, such as iTV Talk, Tod Rahad and Krong Satanakarn, did not often open public discussion on the programs. Rather, the regular format of panel discussions, consisting of elites and some celebrities, tended to focus on national topics rather than local issues. The hosts of many of these public affairs programs depended on their own celebrities status and tended to invite well-known guests, whereas community-oriented programs such as Lan Ban Lan Muang and Tid Ban Tang Muang promoted civic journalism and deliberative democracy more effectively. The latter programs allowed the public to participate in the programs as the main actors and even proposed their own agendas. However, a limited study of three audience focus groups - an expert urban group, a young middle class urban group, and a rural group - found considerable scepticism about the possibility of developing public interest awareness via television programs. The expert and young middle class groups criticised both the hosts and the style of a selection of current affairs programs, which they thought were too serious and also biased. Some also considered that current affairs programs were a platform for the people in power rather than providing a space for the public. Therefore, they rarely watched them. In contrast, the rural group who participated in Lan Ban Lan Muang, believed that the program was useful for development communication. The audience gained information about other communities and used the media as the means to publicise their own community. However, they rarely watched it because the airtime of the program was the same as a popular entertainment program on Channel 3. The researcher used qualitative research methods to collect data, including indepth interviews, focus groups, participant observation, program recording and document analysis. Theoretically, the study has attempted to combine the approaches of western and Thai scholars. The main approach used to explain the relationship between the media and civil society is media and public sphere theory, as introduced by Habermas, and combined with the perspectives on media re-regulation of the Thai scholar Ubonrat Siriyusak. In terms of analysing Watchdog and iTV, the researcher used political economy perspectives to understand decision-making in both organisations. In addition, an organisational culture approach was used to explore conflicts of interest that arose in both organisations due to their different sub-cultures. Civic journalism, framing theory and development communication theory were further employed to examine the television programs and their roles in promoting the public interest and development projects, while the audience groups were considered in the context of participatory communication theory and reception theory.

Abstract:

Doutoramento em Informação e Comunicação em Plataformas Digitais
Desde que surgiu há mais de 50 anos, a televisão sofreu muitas transformações, tanto ao nível tecnológico (por exemplo com a passagem da emissão a preto/branco para cor, o som analógico para digital, a difusão digital) como a nível da sua influência nas sociedades. Entre outros fatores de ordem tecnológica, a consolidação da Internet com o seu elevado nível de personalização, da experiência de utilização, e a sua enorme quantidade de conteúdos disponíveis, catapultou a televisão no sentido de esta se tornar mais interativa. Assim, o telespectador passou a poder usufruir de uma experiência televisiva que pode, por um lado, ser mais participativa, sendo-lhe possível, por exemplo, alvitrar sobre a qualidade de um programa enquanto assiste à sua exibição, e, por outro, ser mais personalizada, possibilitando-lhe, por exemplo, receber conteúdos automaticamente adequados ao seu perfil e contexto. No entanto, esta experiência mais participativa e personalizável carece de uma identificação, idealmente automática e não intrusiva, de quem pode beneficiar da mesma – o telespectador. Contudo, e apesar de significativos avanços na área da televisão interativa, tanto ao nível da infraestrutura de suporte como ao nível dos serviços disponibilizados, a identificação dos utilizadores é, ainda, uma área de estudo com muitos aspetos por compreender. Os seniores, em particular, são grandes consumidores de televisão e representam uma fatia muito considerável das pessoas que podem beneficiar das potencialidades disponibilizadas pela interatividade presente em muitos serviços atuais. Um número crescente destes serviços são desenhados com o objetivo de promoverem um envelhecimento ativo e um concreto apoio à vida, pelo que os seniores podem beneficiar, em vários aspetos do seu quotidiano, se os utilizarem. Nesta faixa etária, a identificação de utilizadores tem, como elemento potenciador da experiência de utilização, um papel especialmente importante ao nível de um aproveitamento personalizado e dirigido destes serviços. No entanto, atendendo às diferentes combinações de características físicas, sensoriais, cognitivas e, mesmo, de literacia digital que tipificam os seniores, perspetivou-se existir uma dependência do perfil do utilizador na seleção do método de identificação mais adequado, os quais podem ser baseados, por exemplo, num leitor de impressões digitais, instalado no telecomando; na leitura de uma wearable tag ou de um cartão RFiD; no reconhecimento da face e, eventualmente, na voz do utilizador. Assim, a inerente investigação desenrolou-se em várias fases, no sentido de permitir alicerçar a construção de uma matriz de decisão tecnológica que, em função do perfil de utilizador, selecione o sistema de identificação mais adequado. O procedimento metodológico inerente à construção desta matriz de decisão, passou por um longo processo envolvendo utilizadores reais, que se iniciou com a realização de entrevistas exploratórias com o objetivo de permitir conhecer melhor os seniores e a forma como estes encaram a tecnologia e, mais concretamente, a televisão interativa. Foi depois implementado um protótipo de alta-fidelidade, completamente funcional, para a realização de testes com o objetivo de perceber qual a preferência relativamente a um subconjunto de tecnologias de identificação. Estes testes, uma vez que não permitiram testar todas as tecnologias em estudo, revelaram-se inconclusivos, porém permitiram reforçar a necessidade de identificar e caracterizar os referidos aspetos do perfil do utilizador que podem interferir na sua preferência relativamente ao sistema de identificação. As características identificadas constituíram-se como os parâmetros de entrada da matriz, sendo que para preencher as respetivas células realizaramse testes de aceitação, com um conjunto de seniores, tendo por base um protótipo, wizard of oz, especificamente implementado para permitir experienciar todas as tecnologias em estudo. Estes testes foram precedidos pela avaliação das capacidades funcionais dos participantes, nos diversos parâmetros definidos. Este texto relata, assim, todo o processo de investigação que foi conduzido, terminando com uma descrição de exemplos de utilização da matriz de decisão implementada e com a identificação de potenciais caminhos de desenvolvimento deste trabalho.
Television underwent by many socio-technological changes since its beginning in the fifties. Beyond some inherent technological factors like the transition from black and white to color and the digitalization of both audio and video components, the consolidation of the Internet with its high level of customization of user experience and massive amount of available content, helped television to be driven towards an interactive dimension. Thus, the viewer happened to be able to enjoy from a viewing experience that can, first, be more participatory as he can, for example, vote in TV shows or express his opinion about the quality of a TV program and, second, be more personalized allowing him, for instance, receiving TV contents appropriated to his profile and context of use. However, this more participatory and customizable experience lacks of an automatic identification process of the person/s that is/are watching TV. Despite significant advances in the area of interactive television (iTV), the automatic identification of viewers, especially if a non-intrusive way is at stake, is still a research area with many unsolved topics. Elder people, in particular, are major consumers of television and represent a very sizable chunk of viewers that can benefit from the potential offered by this interactivity in many types of services. A growing number of these services are designed with the aim to promote active aging and life support, thus seniors can benefit in various aspects of their daily lives, if they use them. In this age group, the automatic identification of viewers has a special role in a personalized and targeted usage of these services, acting as an enhancer of the user experience. However, due to a broad range of physical, sensorial, cognitive and digital literacy characteristics inherent to the elderly, it was envisaged that the definition of the most suitable viewer identification technology would be dependent of the actual user/viewer profile. Actually, the user identification method can be based in several technology options, e.g. a fingerprint reader placed in the remote, a wearable tag, an RFID card, a facial or a voice recognition system, making it necessary deciding on the best approach for each possible viewer profile. The research was carried out in order to leverage the design of a decision matrix that, using the characteristics of the senior's profile, computes the most suitable viewer identification method. The methodology used to build the matrix was based on multiple sets of interviews and evaluation sessions with elderly viewers in a longitudinal prototyping process. We started with a set of exploratory interviews that allowed a better understanding how seniors see iTV technology. After, it was implemented a fully functional prototype (that allowed to test a particular set of identification technologies), that was evaluated by seniors participants, to find a clear trend about the preference of identification technologies. Despite these tests were a step forward (since they allow to understand that viewer’s characteristics can influence their preferences about the identification technology), they were not totally conclusive mainly due to the fact that they only had allowed testing a particular set of technologies among all that are referenced in this research. The aforementioned characteristics became the inputs of the decision matrix, leading to a new set of tests to start filling in its cells. These tests were based on a wizard of oz prototype that allowed participants to experiment all identification technologies referred in this research. All these tests with seniors were made at their homes preceded of the evaluation of their functional characteristics (the ones identified in previous test and that can influence viewer's preferences). The document ends reporting the main conclusions and examples of the matrix usage and with some points to next steps of this work.

Abstract:

This qualitative study explored the quality of technology associated with interactive video (ITV) classes in distance education programs and the resulting satisfaction of the instructors teaching this format. The participants were full time instructors of a rural community college that used the ITV format. Community college ITV instructors are knowledgeable about the ITV technology and are in need of research that explores the satisfaction of that technology. Distance education theory, social constructivism, individual and collaborative learning, and technology formed the foundation for the research. Grounded theory was used to generate a theory about the perceptions of the instructors. Data collected included surveys, interviews, and observations of the interviews. Data were analyzed using theoretical sampling, constant comparison, open coding, axial coding, and selective coding. Analysis indicated that instructors' perceived greater satisfaction teaching in an ITV environment when the structure of the class was optimum for the course, the audio/visual technology worked effectively, the Web-enhanced component of the course ran smoothly, IT was available, quality training was offered, and transactional distance was perceived as minimal. This grounded theory provides positive social change for other educators and administrators who teach ITV by guiding their efforts to use ITV course delivery systems in ways that ensure the fulfillment of needs for both instructors and their students.

Abstract:

Interactive television (iTV) is an umbrella term used to cover the convergence of television with digital media technologies such as computers, personal video recorders, game consoles, and mobile devices, enabling user interactivity. Increasingly, viewers are moving away from a "lean back" model of viewing to a more active "lean forward" one. When fully realized on a widespread scale in the United States, our current experience of watching television will be dramatically transformed. Because iTV is a new medium in its own right, however, standards for iTV programming and interaction in the United States remain undefined. This document identifies and articulates interaction design principles for interactive television programming in the United States. Chapter one presents a brief survey of the field as it stands in 2005. In chapters two and three, I categorize iTV by platforms and by persistent television genres, and present representative examples for each category. In chapter four, I provide an overview of existing design standards in related areas. Insights from chapters two, three, and four all serve to inform chapter five, in which I propose principles for iTV interaction design by looking closely at existing designs (both deployed and prototyped), conventions, and patterns of interaction. My analyses are rooted in visual culture and human-computer interaction design principles, and the design principles I offer are abstracted from the applications I analyze within this framework. Finally, in chapter six, I offer some conclusions and thoughts for future directions.

Abstract:

This thesis analyses the early infrastructural development of Southern Television, the now-defunct franchise company that was created in 1958 to serve the South of England on behalf of Independent Television (ITV). In particular, it identifies how Southern Television's status as a regional broadcaster affected the implementation and development of its policies, regulations, resources and practices from the late 1950s to the late 1960s. Histories of regional broadcasting have heretofore focused on programmes that evoke regional culture, and more often than not these histories have ignored the South in favour of northern cultures. This thesis approaches the history of regional broadcasting from a different perspective, one that considers where the region was visible in the internal workings of a regional broadcaster, as opposed to identifying the region in that broadcaster's output. This research utilises a wide variety of archival documentation from Southern Television, as part of an AHRC Collaborative Doctoral Award project with the BFI National Archive. As such, it offers an unprecedented historical account of regional, commercial television production, which is drawn almost entirely from the political, operational and cultural contexts that are only evidenced behind the camera. Correspondence, budgets, administrative and managerial documentation portray the day-to-day life of a television company that would otherwise be lost. The history of ITV remains a neglected subject in television studies, and this case study contributes a new understanding of the development of commercial broadcasting that takes into account the singular regional structure that characterised the emergence of ITV in Britain.

Abstract:

This study is an account of how the interplay between socio-political concerns and economic objectives shaped programme supply make/buy decisions for establishing UK commercial television and the ongoing programme supply arrangements of its main terrestrial operator ITV (Independent Television). A main interest is to build a credible explanation of why make/buy decisions for programmes shown on ITV diverged from initial expectations that they would be determined on a competitive basis. The enquiry examines the underlying reasons that affected these decisions to show how socio-political fear of the potential impact commercial television might have on UK society impinged on the outcomes that prevailed and how changes occurred as this fear diminished. To achieve this aim, the investigation first focuses on the make/buy conditions impinging on decisions that led to the start up phase of UK commercial television. It is followed by a detailed examination of how programme supply make/buy arrangements for ITV evolved in the initial (1954 - 1964) and later (1990 - 2001) contract periods. These two contract periods are focused on as distinctive points of reference for guiding and containing the research within practical boundaries. The first represents a time when programme supply make/buy options were first established and the second when these options were substantively modified. An historical case study approach is applied, drawing upon state archives, interviews and programme supply statistics to explain the outcomes that prevailed.

Abstract:

Les interfaces graphiques étaient la plupart du temps statiques, et représentaient une succession d'états logiciels les uns après les autres. Cependant, les transitions animées entre ces états statiques font partie intégrante des interfaces utilisateurs modernes, et leurs processus de design et d'implémentations constituent un défi pour les designers et les développeurs. Cette thèse propose un processus de conception de systèmes interactifs centré sur les animations, ainsi qu'une architecture pour la définition et l'implémentation d'animations au sein des interfaces graphiques. L'architecture met en avant une approche à deux niveaux pour définir une vue haut niveau d'une animation (avec un intérêt particulier pour les objets animés, leurs propriétés à être animé et la composition d'animations) ainsi qu'une vue bas niveau traitant des aspects détaillés des animations tels que les timings et les optimisations. Concernant les spécifications formelles de ces deux niveaux, nous utilisons une approche qui facilite les réseaux de Petri orientés objets pour la conception, l'implémentation et la validation d'interfaces utilisateurs animées en fournissant une description complète et non-ambiguë de l'ensemble de l'interface utilisateur, y compris les animations. Enfin, nous décrivons la mise en pratique du processus présenté, illustré par un cas d'étude d'un prototype haute-fidélité d'une interface utilisateur, pour le domaine de la télévision interactive. Ce processus conduira à une spécification formelle et détaillée du système interactif, et incluera des animations utilisant des réseaux de Petri orientés objet (conçus avec l'outil PetShop CASE)
Graphical User Interfaces used to be mostly static, representing one software state after the other. However, animated transitions between these static states are an integral part in modern user interfaces and processes for both their design and implementation remain a challenge for designers and developers. This thesis proposes a process for designing interactive systems focusing on animations, along with an architecture for the definition and implementation of animation in user interfaces. The architecture proposes a two levels approach for defining a high-level view of an animation (focusing on animated objects, their properties to be animated and on the composition of animations) and a low-level one dealing with detailed aspects of animations such as timing and optimization. For the formal specification of these two levels, we are using an approach facilitating object-oriented Petri nets to support the design, implementation and validation of animated user interfaces by providing a complete and unambiguous description of the entire user interface including animations. Finally, we describe the application of the presented process exemplified by a case study for a high-fidelity prototype of a user interface for the interactive Television domain. This process will lead to a detailed formal specification of the interactive system, including animations using object-oriented Petri nets (designed with the PetShop CASE tool)

Abstract:

Mestrado em Comunitação Multimédia
Ao longo dos últimos anos, a televisão é vista como “um médium enriquecedor do desenvolvimento humano e (com) um forte contributo de sustentabilidade da democracia participativa” (Lopes & Pereira, 2011). A evolução deste meio de comunicação quer ao nível tecnológico quer, ao nível dos serviços oferecidos, obrigou as diversas operadoras de serviços televisivos a disponibilizar conteúdos mais atrativos e diversificados. Assim, quebrou-se a passividade que a emissão tradicional de televisão introduzia aos telespetadores, tornando-os intervenientes em todo este processo, criando um novo paradigma – o da Televisão Interativa (Violante et al., 2015). Esta metamorfose inerente ao conceito de Televisão Interativa (iTV) permite aos telespectadores a utilização de novos serviços, possibilitando novas experiências de interação e participação (Oliveira, 2014). Os seniores, em particular, são grandes consumidores de televisão e representam uma fatia muito considerável das pessoas que podem beneficiar das potencialidades disponibilizadas pela interatividade presente em muitos serviços atuais (Silva, 2014) visto que são, muitas vezes, confrontados com inesperadas alterações nos diversos serviços sociais. Os regimes de comparticipação de medicamentos, as alterações das fórmulas de cálculo das reformas e as novas regras no regime de arrendamento são apenas alguns exemplos. Na maior parte das vezes, estas alterações levam demasiado tempo a chegar até aos seniores, devido às limitações tecnológicas, sensoriais e cognitivas que surgem, por norma, com o envelhecimento. É importante compreender que o envelhecimento acarreta algumas limitações, e para isso é necessário elencar um conjunto de normas, para o desenvolvimento de conteúdos audiovisuais, que minimizem algumas dessas dificuldades. De forma a aproveitar todo o potencial da Televisão Interativa, tendo em conta as limitações associadas ao envelhecimento, pretendeu-se elencar um conjunto de princípios orientadores para o desenvolvimento de conteúdos audiovisuais, sobre serviços sociais, através da avaliação de um conjunto de vídeos-exemplo. Para atender convenientemente às necessidades do cidadão sénior foi necessário identificar os hábitos televisivos, o nível de literacia tecnológica, o grau de dificuldade na realização das tarefas diárias a nível físico e cognitivo, bem como identificar os principais meios de informação presentes no dia-a-dia do cidadão sénior. Para tal, foi indispensável a elaboração de um inquérito por questionário que, simultaneamente, foi complementado com entrevistas exploratórias. De seguida, e após a visualização dos conteúdos audiovisuais previamente selecionados, recorreu-se, novamente, aos métodos de recolha de dados anteriormente referidos com o intuito de analisar e avaliar tecnicamente os conteúdos apresentados.Por fim, solicitou-se a cada participante que avaliasse o seu estado emocional após a exposição de cada conteúdo audiovisual, recorrendo à escala pictórica SAM (Self-Assessment Manikin) (Lang, 1980). Os resultados alcançados indicam que existe potencial para que o conjunto de normas de desenvolvimento de conteúdos audiovisuais para seniores, sejam consideradas e integradas nas dinâmicas televisivas diárias.
Over the years, television has been seen as a means of enriching human development. The technological evolution of this means of communication has led broadcasters to deliver more attractive and diversified contents. Hence, traditional broadcasting has evolved from the traditional passivity to the granting of a participatory role for viewers, creating a new paradigm – Interactive Television. Senior citizen viewers are great consumers of television and represent a considerable portion of people, who can take advantage of the interactivity potentialities. Most of the time, changes in social services take too long to reach senior citizens due to their technological, sensory or cognitive limitations, which tend to occur with the aging process. In this exploratory study, the research team aims to find principles for the development of content about social services, considering iTV potential and the limitations of senior’s citizen’s viewers. To accomplish this goal, the research team developed audiovisual content, videos regarding social services with different approaches on technological aspects. The evaluation of its effectiveness was by means of inquiry with direct questions on the material that was showcased.

Abstract:

Doutoramento em Informação e Comunicação em Plataformas Digitais
As infraestruturas de televisão interativa atualmente existentes possibilitam a integração de uma grande variedade de recursos e serviços, possibilitando aos utilizadores novas experiências de interação e participação. Para a maioria dos telespetadores, o uso de serviços interativos não acarreta grandes dificuldades; no entanto, para públicos com necessidades especiais, por exemplo para pessoas com défice visual, essa tarefa torna-se complexa, dificultando, ou mesmo impedindo, que estes utilizadores possam beneficiar deste tipo de serviços. Portugal não é uma exceção neste contexto, existindo um número significativo de utilizadores com défice visual (UDV) que não beneficiam totalmente das potencialidades do paradigma televisivo atual. Neste âmbito, o projeto de investigação que suporta esta tese explora a problemática do Design Universal aplicado à Televisão Interativa (iTV) e tem como objetivos a conceptualização, prototipagem e validação de um serviço de iTV adaptado especificamente a UDV, visando promover a sua inclusão digital. Para cumprir estes objetivos, a investigação dividiu-se em três etapas distintas. Na primeira etapa, a partir da Teoria Fundamentada nos Dados, foram identificadas as dificuldades e necessidades dos UDV enquanto consumidores de conteúdos televisivos e serviços de audiodescrição; foi selecionada a plataforma tecnológica mais adequada para o suporte do serviço prototipado; e foi definido um conjunto de princípios orientadores de design (POD’s) de interfaces de televisão interativa específico para este público-alvo. Inicialmente foram efetuadas duas entrevistas a 20 participantes com défice visual, para determinar as suas dificuldades e necessidades enquanto consumidores de conteúdos televisivos e serviços de audiodescrição. De seguida, foi realizada uma entrevista a um perito responsável pelo processo de transição para a TDT em Portugal (inicialmente considerou-se que a TDT seria uma plataforma promissora e poderia suportar o protótipo) e efetuada a revisão da literatura sobre POD’s para o desenvolvimento de interfaces para serviços iTV dirigidos a pessoas com défice visual. A partir dos resultados obtidos nesta etapa foi possível definir os requisitos funcionais e técnicos do sistema, bem como os seus PODs, tanto ao nível da componente gráfica, como de interação. Na segunda etapa foi concetualizado e desenvolvido o protótipo iTV adaptado a UDV ‘meo ad+’, com recurso à plataforma tecnológica IPTV da Portugal Telecom, seguindo os requisitos e os princípios de design definidos. Relativamente à terceira etapa, esta contemplou a avaliação do serviço prototipado, por parte de um grupo de participantes com défice visual. Esta fase do trabalho foi conduzida através do método de Estudo Avaliativo, possibilitando, através de testes de usabilidade e acessibilidade, complementados com entrevistas, compreender se o serviço prototipado ia efetivamente ao encontro das necessidades deste tipo de utilizadores, tendo-se observado que os participantes que estiveram envolvidos nos testes ao protótipo mostraram-se satisfeitos com as funcionalidades oferecidas pelo sistema, bem como com o design da sua interface.
The currently existing interactive television infrastructures enable the integration of a wide variety of resources and services, enabling users with new interaction and participation experiences. For the majority of viewers, the use of interactive services does not imply significant difficulties, however, for audiences with special needs, for example for people with visual impairment, this task becomes complex, hindering, or even preventing these users to benefit from such services. Portugal is not an exception in this context, since there are a significant number of visually impaired users (VIU) who do not entirely benefit from the capabilities of the current television paradigm. In this framework, the research project that supports this thesis explores the Universal Design problem applied to Interactive Television (iTV) and its main aims are the conceptualization, prototyping and validation of an iTV service adapted specifically for VIU, promoting their digital inclusion. To accomplish these goals, the research was divided into three different stages. In the first stage, from the Grounded Theory, the difficulties and needs of the VIU as consumers of television contents and audio description services was identified; the most appropriate technological platform to support the prototyped service was selected; and a specific set of design principles and guidelines (DPG’s) of interactive television interfaces for this target audience were defined. Initially two interviews were conducted with 20 visually impaired participants, to determine their difficulties and needs as consumers of television contents and audio description services. Thereafter, an interview with an expert responsible for the DTT transition process in Portugal was carried out (initially it was considered that the DTT would be a promising platform and could support the prototype) and a literature review of DPG’s for the development of iTV interfaces for services focused on persons with visual impairment was performed. Based on the results obtained in this stage it was possible to define the functional and technical requirements of the system, as well as its DPG’s, relating to the graphical and interaction components. In the second stage the iTV prototype adapted to VIU ‘Meo ad+’ was conceptualized and developed, using the ‘Portugal Telecom’ IPTV technology platform, following the defined requirements and design principles. Regarding the third stage, it included the prototyped service evaluation by a group of visually impaired participants. This stage was conducted through the Evaluative Study method, enabling, via usability and accessibility tests, complemented by interviews, to understand whether the prototyped service effectively met the needs of this type of users, of the evaluation, having being observed that the participants who were involved in the prototype tests showed satisfaction with the features offered by the system as well as with the design of its interface.

Abstract:

This project explores the ability to use “smart” media devices for the TV set as platforms for interactive TV shows. The research approach was research-based design where a prototype was designed, developed, and evaluated with user tests. The project used a Swedish television game show called “På spåret” and an application for tvOS on Apple TV was developed, which allow users to play along with the show. The software implements a model-view-controller architecture and uses the AVFoundation framework for playing video streams together with the UIKit framework to create interactive overlay views. The interactive elements were synchronized with the video by the usage of metadata. The user test results show that the interactive TV show gained in both entertainment and excitement among the users. Further conclusions are that interactive elements can be available both during playing or paused video and the context should decide which mode. A multimodal interface with gestures and sound as feedback seems to be a good option, based on user tests. This project also presents a solution for user input with the remote, using a virtual keyboard together with filter function. The user filtering out the input from a data set to minimize the typing of letters. User tests show that the filter solution seems to be a good option for text input in a specific domain or category of allowed input. However, for free text input, a better method is required.

Abstract:

In this study, I examine how the BBC and ITV News at Ten covered the Mid Staffordshire hospital scandal between 17 March 2009 and 17 March 2014. The analysis focuses on the construction of healthcare and deviance in TV health news storytelling, and the institutional and individual social actors involved in the process. The failings themselves included the mistreatment and sometimes death of hundreds of patients at a local hospital in Stafford. These events led to an institutional scandal, where not only the local institution but the entire NHS, its culture and its leadership were identified as deviant folk devils. Drawing on approaches from sociology, criminology, journalism and media studies, I analyse the case study from a social constructivist perspective. The theoretical and conceptual framework includes storytelling, discourse, encoding and scandal, whilst the methodology combines analyses of TV news content with interviews with BBC and ITV news workers. Thereby, I engage with the reports themselves, the process of encoding them, and the power relations involved. The production of TV health news was negotiated between health and political specialists, who used different narrative strategies, such as interviews, to make the storytelling engaging. As for the TV coverage of the Mid Staffordshire hospital scandal, it went through four different phases: activations, reactions, amplification and justice. Each phase had its characteristics in terms of social actors and scandal processes, which served to drive the storytelling forward until the narrative became fixed by 2014. As such, I found that the process of scandalising the NHS reflects deeper and ongoing social changes regarding the media’s construction of powerful institutions and individuals as well as the wider issue of trust in authorities.

Mestrado em Gestão e Estratégia Industrial
Esta dissertação, dedicada à abordagem da temática da internacionalização e competitividade das empresas portuguesas, e, nomeadamente, das de pequena e média dimensão, começa, na sua primeira parte, por tentar identificar as principais características do novo enquadramento competitivo internacional, situando mudanças ou processos fundamentais como a globalização, a emergência de novas formas de capitalismo, menos hierárquicas e mais cooperativas, a reconfiguração das cadeias de valor empresariais, puxada pela procura e pela redução do ciclo de vida das tecnologias e produtos, e o aprofundamento e desencadeamento de experiências de integração regional, em variados pontos do globo. Seguidamente, proceder-se-á à fundamentação teórica desta evolução, enumerando os principais contributos das teorias do negócio internacional e tecendo algumas considerações acerca da sua validade actual. Na segunda parte deste trabalho, passam-se em revista as principais tendências, ao longo, sobretudo, da última década, da internacionalização da economia e empresas portuguesas, numa perspectiva macro e microeconómica - não obstante os avanços registados nos tempos mais recentes, esta é, ainda, relativamente truncada, limitada e desequilibrada -, para depois analisar os desafios fundamentais que se colocam às empresas portuguesas e, em particular, às nossas PME, no domínio, nomeadamente, da internacionalização e/ou globalização das suas actividades. Finalmente, na terceira parte desta tese, é particularizada a análise até aí desenvolvida, para a indústria têxtil e de vestuário (ITV) nacional, em face do seu carácter estratégico para a economia portuguesa. Os novos desafios da internacionalização e competitividade referenciados na segunda parte têm aqui uma especial importância na medida em que o actual posicionamento competitivo das nossas ITV, baseado na exploração excessiva do factor preço e na exportação de serviços de baixo valor acrescentado, tem os seus dias contados, havendo que promover a sua substituição por um outro que aposte fortemente numa maior articulação técnico-comercial, na qualidade, flexibilidade, inovação e design, a nível empresarial, no quadro de uma maior orientação para o consumidor e de uma progressiva 'clusterização' e de um reforço e reequilíbrio da internacionalização das ITV nacionais.
The major concern of this dissertation is the study and analysis of internationalization and competitivo potential of portuguese firms, taking into account, in particular, the case of small and middle sized companies (SME). In its first part, we try to identify the main characteristics of the new intemational competitivo environment, focusing on fundamental changes or processes such as globalization, the emergence of new forms of capitalism, less hierarchical and more co-operative, the reconfiguration of value chains, pushed forward by new tendencies in demand and the progressivo reduction of products and technologies life-cycles, and the increasing role of regional integration throughout the world. Further, the theoretical foundations of these evolutions will be examined, by listing and analysing the major contributions of intemational business theories and making some considerations regarding their today's validity. In the second part of the research, we will take a close look at the major tendencies, throughout, mainly, the last decade, of internationalization of portuguese economy and enterprises, in a macro and microeconomic perspective - despite the recent advances, it is still relatively limited and unbalanced followed by the analysis of the fundamental changes and challenges that portuguese companies, specially SME, must face as far as the internationalization and globalization of their activities is concerned. Finally, in the third part of this thesis, we will focus on the national textile and garment industry (TGI), essentially due to its strategic importance for the portuguese economy. The new challenges of internationalization and competitiveness, mentioned in the second part, have a special importance when we deal with this sector, since today's competitive positioning of our TGI, sustained, particularly, on excessive exploitation of the price factor and on exportation of low value-added services, has no future. Its substitution has to be supported by a new competitive model that favours and prometes a greater articulation between research, technical, productive and commercial activities, new competitive non-cost factors like quality, flexibility, productivity, innovation and design, in entrepreneurial terms, a moreeffective orientation towards customers, leading to a progressivo clustering of portuguese TGI, in aneffort to have internationalization and globalization of its activities strengthened and more balanced.

Full text

Abstract:

In this Thesis, I systematize, clarify, and expand the current theory of emotion based on the principles of predictive processing-the interoceptive inference view of emotion-so as to show the following: (1) as it stands, this view is problematic. (2) Once expanded, the view in question can deal with its more pressing problems, and it compares favourably to competing accounts. Thus, the interoceptive inference view of emotion stands out as a plausible theory of emotion. According to the predictive processing (PP) framework, all what the brain does, in all its functions, is to minimize its precision-weighted prediction error (PE) (Clark, 2013, 2016; Hohwy, 2013). Roughly, PE consist in the difference between the sensory signals expected (and generated) from the top-down and the actual, incoming sensory signals. Now, in the PP framework, visual percepts are formed by minimizing visual PE in a specific manner: via visual perceptual inference. That is, the brain forms visual percepts in a top-down fashion by predicting its incoming lower-level sensory signals from higher-level models of the likely (hidden) causes of those visual signals. Such models can be seen as putting forward content-specifying hypotheses about the object or event responsible for triggering incoming sensory activity. A contentful percept is formed once a certain hypothesis achieves to successfully match, and thus supress, current lower-level sensory signals. In the interoceptive inference approach to interoception (Seth, 2013, 2015), the principles of PP have been extended to account for interoception, i.e., the perception of our homeostatic, physiological condition. Just as perception in the visual domain arises via visual perceptual inference, the interoceptive inference approach holds that perception of the inner, physiological milieu arises via interoceptive perceptual inference. Now, what might be called the interoceptive inference theory of valence (ITV) holds that the interoceptive inference approach can be used so as to account for subjective feeling states in general, i.e., mental states that feel good or bad-i.e., valenced mental states. According to ITV, affective valence arises by way of interoceptive perceptual inference. On the other hand, what might be called the interoceptive inference view of emotion (IIE) holds that the interoceptive inference approach can be used so as to account for emotions per se (e.g., fear, anger, joy). More precisely, IIE holds that, in direct analogy to the way in which visual percepts are formed, emotions arise from interoceptive predictions of the causes of current interoceptive afferents. In other words, emotions per se amount to interceptive percepts formed via higher-level, content-specifying emotion hypotheses. In this Thesis, I aim to systematize, clarify, and expand the interoceptive inference approach to interoception, in order to show that: (1) contrary to non-sensory theories of affective valence, valence is indeed constituted by interoceptive perceptions, and that interoceptive percepts do arise via interoceptive perceptual inference. Therefore, ITV holds. (2) Considering that IIE exhibits problematic assumptions, it should be amended. In this respect, I will argue that emotions do not arise via interoceptive perceptual inference (as IIE claims), since this assumes that there must be regularities pertaining to emotion in the physiological domain. I will suggest that emotions arise instead by minimizing interoceptive PE in another fashion. That is, emotions arise via external interoceptive active inference: by sampling and modifying the external environment in order to change an already formed interoceptive percept (which has been formed via interoceptive perceptual inference). That is, emotions are specific strategies for regulating affective valence. More precisely, I will defend the view that a certain emotion E amounts to a specific strategy for minimizing interoceptive PE by way of a specific set of stored knowledge of the counterfactual relations that obtain between (possible) actions and its prospective interoceptive, sensory consequences ("if I act in this manner, interoceptive signals should evolve in such-and-such way"). An emotion arises when such knowledge is applied in order to regulate valence.

Abstract:

This thesis uncovers and analyses the relationship between forms of talk on British television between 1970-1990, and the uneven transformations in gender politics that occurred in this period, which encompasses both the second wave feminist movement and the rise of neoliberal politics. It presents five historical case studies of talk-based television programmes from across this time period: No Man’s Land (Associated Television/ITV, 1973), Good Afternoon! (Thames Television/ITV, 1971-1984), Pictures of Women: Sexuality (Channel 4, 1984), Watch the Woman (Channel 4, 1985), and Question Time (BBC One, 1979-present). These case studies offer a deliberate selection of television texts that differ according to their institutional contexts; their position in the schedules; their status in existing broadcasting histories; their discursive arrangements; and their modes of address. The thesis seeks to consider how the communicative ethos of television talk has been gendered in three key ways: at the level of production - in the sense of when, how, and why television spaces have been opened up for gendered forms of talk in relationship to wider shifts in gender politics; at the level of the text - in terms of how the discursive arrangements of talk-based programmes have worked to include, exclude, legitimise or disavow women’s voices; and at the level of critical reception - in the sense of how television talk has been evaluated in profoundly gendered terms. The thesis is methodologically innovative because it theorises gendered forms of television talk in relationship to histories of television production, as well as to broader political, cultural and gender histories. It carries out important empirical ‘recovery work’ of hidden women’s television histories through the presentation of original archival research. It also presents theoretical work, which re-evaluates the distinctive communicative ethos of television – or its “sociability” in light of feminist theories of language, gender and power. Moreover, it sheds some historical light on why the institutional parameters of television still delimit the available spaces for women's speech.

Abstract:

In November 2010, the coalition government published its seminal The White Paper, The Importance of Teaching. Its recommendations sought to reform Initial Teacher Training (ITT) so that more training was school-based; to create a new national network of ‘Teaching Schools’ that gave outstanding schools in England a leadership role in the initial training and professional development of teachers. This thesis critically analyses the subsequent changes in relationships and tensions between universities and schools as the reforms were implemented. The consequent increase in the number of routes into teaching, coupled with more autonomy devolved to schools in relation to Initial Teacher Preparation (ITP), has served to jeopardise university-based preparation. The changing notions of pedagogy and practice in school-led initial teacher preparation alter the significance of theory in ITP and ultimately question the future for university-led initial teacher education. What constitutes effective teacher preparation is explored through a series of semi-structured interviews drawn from a small, reputational sample across the field of education. This provides the data that reveals a contemporary dichotomy between ‘training’ and ‘education’ that challenges the relevance of a theoretically informed teacher education in favour of ‘on the job training.’ From the discussion of the contested data provided by reputational sample, an outcome of the current changes could result in a peripheral role for universities in ITP. In particular, undergraduate provision, such as the B.Ed, was threatened because it did not provide a sufficient depth of subject knowledge; a shift to post-graduate school-based preparation and a reliance on assessment-only routes renders the role of the universities defunct. The findings from the analysis of the reputational sample were further examined in the workplace through questionnaire given to academics and partnership school mentors working in delivering ITP in an East Midlands University. The tensions between ‘training’ and education and the role of universities in initial teacher preparation were mirrored by teachers and academics. In conclusion, the changes made by the coalition government have made the future of ‘teacher education’ uniquely fragile.

Itô’s Lemma Ausarbeitung im Rahmen des Seminars "Finanzmathematik", SS 2009 Die Arbeiten des japanischen Mathematikers Kiyosi Itô aus den 1940er Jahren bilden heute die Grundlage der Theorie stochastischer Integration und stochastischer Differentialgleichungen. Die Ausarbeitung beschäftigt sich mit Itô's Kalkül, in dem zunächst das Itô-Integral bezüglich diverser Integratoren bereitgestellt wird, um sich anschließend mit Itô's Lemma bzw. der Itô-Formel als grundlegendes Hilfsmittel stochastischer Integration zu widmen. Am Ende wird ein kurzer Ausblick auf das Black-Scholes-Modell für zeitstetige Finanzmärkte vollzogen. Grundlage für die Ausarbeitung ist das Buch "Risk-Neutral Valuation" von Nicholas H. Bingham und Rüdiger Kiesel.

Abstract:

Il presente elaborato, partendo dalla storia della professione dell'interprete, cercherà di individuare quali sono le difficoltà che i professionisti del campo si trovano ad affrontare nel nostro periodo storico e come si sono adattati a un progresso tecnologico continuativo e rapido. Da qui, proporrà la teorizzazione di un software che comprenda tutti gli strumenti utili per gli interpreti professionisti e in formazione. Per farlo, in una prima parte verranno esposte delle nozioni di neurolinguistica utili a comprendere in che modo il cervello di un interprete viene sollecitato, quali sono le difficoltà cognitive e le possibili conseguenze negative a cui va incontro e, in generale, quali metodi è necessario adottare per abituare la propria mente a svolgere tutti i passaggi necessari a portare a termine un incarico nel modo corretto. Nella seconda parte dell’elaborato si parlerà del rapporto tra interprete, formazione e tecnologia. Verrà spiegato brevemente in cosa consiste la formazione di un interprete di conferenza e quali sono gli esercizi proposti agli studenti per creare delle basi solide che fungano da fondamenta per la loro futura vita professionale. La terza parte dell’elaborato si propone di teorizzare l’ideazione di un toolkit, battezzato appunto InterpreToolkit, che racchiuda tutte le funzioni utili alla formazione e alla vita professionale degli interpreti descritte all’interno della seconda sezione. Le diverse funzioni verranno spiegate singolarmente in dettaglio e verrà sottolineata l’importanza che hanno per chi fa questo lavoro o per chi si sta esercitando per svolgerlo in futuro. Nella quarta e ultima parte dell’elaborato verranno forniti degli esempi pratici della possibile applicazione di InterpreToolkit sia nell’ambito della formazione che in quello professionale, per dimostrarne la grande versatilità. Benché al momento non sia possibile sviluppare ITK, uno degli obiettivi del progetto è cercare i mezzi per poterlo fare nel futuro prossimo.

This thesis exposes a survey of new theories, researches and new approaches in the areas of narratology and ludology. It also exposes investigations on feasibility of using the knowledge acquired in such areas in developing new interactive contents for Digital Interactive TV (iTV). Initially the text shows an objective description of technical and operational aspects of the iTV. In the sequence, the narratologists and ludologists propositions are discussed. Narratology is a line of thought that studies the possibilities of interactive dramas a narrative structure in which the user can immerse as a character that he/she plays in first-person. Ludology is a line of thought that studies computer games virtual environments and worlds where the user can simulate, explore, face challenges, etc. The present research tries to survey the most relevant theoretical approaches and propositions from both areas narratology and ludology. Based on such propositions and theories we evaluate the possibility of introducing interactive dramas, new forms of games and new interactive programs in the iTV environment.
A presente pesquisa expõe um levantamento sobre recentes teorias, pesquisas e abordagens nas áreas da narratologia e da ludologia. Baseado nas propostas e teorias mais relevantes de ambas as áreas, analisa-se as possibilidades de introdução de narrativas interativas, de novas formas de jogos e de novos aplicativos televisuais na TV Digital Interativa (TVi). Na primeira parte, uma descrição objetiva sobre os aspectos técnicos e operacionais da TVi é apresentada. Na seqüência são mostradas as propostas narratológicas. Narratologia é uma linha de pensamento que estuda a criação de dramas interativos estruturas narrativas nas quais o usuário pode imergir para vivenciar um papel em primeira-pessoa. Na terceira parte da pesquisa as propostas ludológicas são abordadas. Ludologia é uma linha de pensamento que estuda os jogos computacionais estruturas de mundos virtuais nos quais o usuário pode simular situações, explorar mundos, enfrentar desafios, etc. Dessa forma, o presente trabalho busca outras formas interativas de expressão no novo meio que surge, a TVi.

[EN] This thesis is focused on the synthesis of new zeolitic structures using phosphorus containing compounds as structure directing agents, and the study of the influence of the presence of phosphorus in the adsorption capacity and acid properties of the zeolites. The phosphazene bases and aminophosphonium cations used in this work have yielded to zeolites with new crystalline structures (ITQ-45, ITQ-52, ITQ-58), as well as have developed new routes of synthesis of already known zeolites, but broadening their range of compositions (DON, RTH, ITE, STF), and these have allowed obtaining the synthetic analogue (ITQ-47) of the natural zeolite boggsite (BOG) by first time.

Abstract:

Within Human-Computer Interaction, older people (60+) are often characterized as a heterogeneous group of consumers of digital content that use ICTs in a limited way due to age-related changes in functional abilities. By drawing on an ethnographical study of ICTs use by approximately 220 older people over a 5-year period in Spain and on two rapid ethnographical studies, in Denmark and Brazil, with around 180, this dissertation presents an alternative view of ICTs use by older people. The results portray older people as creative digital content creators, provide qualitative evidence of how the process of using ICTs have a positive impact on their perceived well-being and argue that their ICTs use is not so heterogeneous as one might think. This dissertation also suggests that fostering the digital inclusion of older people in developing countries such as Brazil rests upon going beyond providing them with physical / technological infrastructures.
En Interacción Persona-Ordenador, las personas mayores (60+) se suelen caracterizar como un grupo heterogéneo de consumidores de contenidos digitales. Basándose en un estudio etnográfico del uso de las TIC por parte de aproximadamente 220 personas mayores en España durante 5 años, y en otros dos estudios etnográficos, de más corta duración, en Dinamarca y Brasil, con 180, esta tesis presenta una visión alternativa del uso que hacen de las TIC los mayores. Los resultados los presentan como creadores de contenidos digitales creativos, aportan evidencias cualitativas del impacto positivo que tiene utilizar estas tecnologías en su percepción de bienestar y plantea que el uso que éstos hacen de las TIC no es tan heterogéneo como se piensa. Esta tesis también sugiere que incrementar la inclusión digital de los mayores en los países en vía de desarrollo como Brasil se debería basar en ir más allá de proporcionar infraestructuras físicas / tecnológicas.

Abstract:

[EN] Zeolites are microporous crystalline materials showing channels and cavities of molecular dimensions in its interior. The main advantage of these materials is their high thermal and chemical stability as well as the possibility to change the topology and dimensions of the channels and cavities. The main goal of this thesis is to obtain new microporous materials (zeolites) and to widen the composition range of some existing materials, using high-throughput techniques of synthesis and characterization. Four families of structure directing agents (SDAs) are synthesized to obtain these microporous materials and each family is formed by quaternary tetraalkylammonium cations. The size and the volume of the members of each SDA family are increased to carry out a study on how it affects this increase on the type of zeolite that crystallizes Taking into account the importance of each of the various parameters that influence on the hydrothermal synthesis of zeolites and trying to cover all the possible range of composition, a factorial design of experiments for each obtained and characterized SDA is performed. The materials of interest obtained in these experiments are subjected to an exhaustive characterization, in order to determine its structure and properties. Known materials such as zeolites ITQ-3, ITQ-43 and ITQ-44 have been obtained with the SDAs used. But the most important thing of this thesis has been obtaining two new materials, which we refer to as ITQ-57 and ITQ-60. The structure of the zeolite ITQ-60 is completely determined and we can conclude that it is an intergrown material, formed by two layers and presenting a two-dimensional system of 10 x 12 MR channels. On the other hand, the structure of the zeolite ITQ-57 is in its final stages of definition, but we are able to determine is that it presents a large orthorhombic unit cell. We must also mention the obtaining of an optimized synthesis method of the chiral zeolite SU-32. This zeolite has been synthesized as a racemic mixture with a chiral SDA. Using theoretical calculations it has been found that every one of the enantiomers of the SDA is able to lead to the formation of each one of the enantiomers of chiral zeolite. The last step is to synthesize each enantiomer of the SDA separately, allowing us to obtain the two chiral zeolites.
[ES] Las zeolitas son materiales cristalinos microporosos que presentan canales y cavidades de dimensiones moleculares en su interior. La principal ventaja de estos materiales es su elevada estabilidad térmica y química, así como la posibilidad de poder variar la topología y dimensiones de los canales y cavidades. El principal objetivo de esta tesis doctoral es la obtención de nuevos materiales microporosos (zeolitas) y ampliar el rango de composición de alguno ya existente, empleando técnicas de síntesis y caracterización de alta capacidad. Para la obtención de estos materiales microporosos se sintetizan cuatro familias de agentes directores de estructura (ADEs), formadas por cationes tetraalquilamonio cuaternarios. En cada familia de ADEs se aumentan el tamaño y el volumen del agente para poder realizar un estudio sobre cómo afecta este aumento sobre el tipo de zeolita que cristaliza. Obtenidos y caracterizados los agentes directores de estructura, se lleva a cabo un diseño factorial de experimentos para cada uno de ellos teniendo en cuenta cada una de las variables que influyen sobre la síntesis hidrotermal de zeolitas e intentando cubrir el mayor rango posible de composición. Los materiales de interés obtenidos en estos experimentos se someten a una caracterización exhaustiva, para poder determinar su estructura y propiedades. Con los ADEs con los que se ha trabajado se ha obtenido materiales conocidos entre los que destacan las zeolitas ITQ-3, ITQ-43 e ITQ-44. Pero lo más importante de la realización de esta tesis ha sido la obtención de dos nuevos materiales, a los que se les ha denominado ITQ-57 e ITQ-60. La estructura de la zeolita ITQ-60 está completamente determinada y podemos concluir que es un material intercrecido, formado por dos capas y que presenta un sistema bidimensional de canales formados por anillos de 10 y 12 miembros. Por otro lado, la estructura de la zeolita ITQ-57 se encuentra en sus últimas etapas de determinación, pero ha podido determinarse que presenta una celda unidad ortorrómbica de grandes dimensiones. También es de destacar la obtención de un método optimizado de síntesis de la zeolita quiral SU-32. Esta zeolita se ha sintetizado en forma de mezcla racémica y empleando un ADE quiral. Mediante cálculos teóricos se ha podido comprobar que cada uno de los enantiómeros del ADE es capaz de dirigir hacia la formación de cada uno de los enantiómeros de la zeolita quiral. El último paso consiste en sintetizar por separado los enantiómeros del ADE, lo que nos permitirá obtener las dos zeolitas quirales.

El materials d'interés obtinguts en estos experiments es sotmeten a una caracteritzación exhaustiva, per a poder determinar la seua estructura i propietats. Amb els ADEs amb els quals s'ha treballat s'han obtingut materials coneguts entre els quals destaquen les zeolites ITQ-3, ITQ-43 i ITQ-44.

Abstract:

Stochastic differential inclusions can be considered as a generalisation of stochastic differential equations. In particular a multivalued mapping describes the set of equations, in which a solution has to be found. This paper presents an existence result for a special parabolic stochastic inclusion. The proof is based on the method of upper and lower solutions. In the deterministic case this method was effectively introduced by S. Carl.

Resumo: A presente pesquisa procurou analisar as orientações constitucionais atinentes a uma política agrícola que favorecesse a concretização dos fins do Estado de Direito Contemporâneo. Para tanto, o estudo teve como objetivos centrais discutir qual o paradigma de desenvolvimento sustentável adotado pelo sistema jurídico brasileiro, avaliar se a forma de desenvolvimento apregoada no ordenamento é suficiente para satisfazer os interesses coletivos e averiguar qual a efetividade dos dispositivos normativos relativos à atividade agrícola sustentável. O trabalho também buscou observar a possibilidade de o Direito participar, de maneira prospectiva, da regulação e construção de uma atividade agrícola capaz de superar os problemas socioambientais decorrentes da modernização conservadora do campo, a qual acentuou os riscos relativos à perda ou diminuição do potencial produtivo dos recursos naturais localizados no meio rural. A fim de realizar um estudo mais completo sobre esse tema, também foram ponderados os valores norteadores da atividade agrícola, as normas que condicionam a realização dessa atividade e as perspectivas de atuação do Estado, tanto na função de controle, quanto na obrigação de agir na fomentação do desenvolvimento rural e na prevenção de danos ambientais. Como resultado deste trabalho, constatou-se a existência de fundamentos jurídicos para a defesa de um paradigma de desenvolvimento sustentável tridimensional, uma vez que a própria Constituição Federal consagra a integração e harmonização da proteção ambiental com o crescimento econômico e o bem-estar social. Verificou-se, ainda, a existência de instrumentos estatais aptos a exigir que o produtor, quando possível, exerça suas atividades em conformidade com as obrigações prescritas, bem como a previsão e regulamentação de políticas governamentais destinadas à sustentabilidade do empreendimento agrícola

Abstract:

Denna rapport presenterar ett examensarbete på C-nivå där uppdragsgivaren har varit Hedemora Anpassning som bygger om och anpassar bilar för människor med olika funktionshinder. Företaget vill i framtiden ha möjlighet att erbjuda sina kunder ITS-tjänster. Målet med arbetet har varit att undersöka hur ITS skulle kunna stödja de funktionshindrade i deras bilkörning. Syftet delades upp i två delsyften, dels kartläggning av vilka tjänster som finns och är under utveckling inom området ITS – förarstöd och säkerhet samt hur de skulle kunna användas/anpassas för funktionshindrade dels att göra en undersökning av vilka behov de funktionshindrade har av ITS. De metoder som använts har varit kvalitativa intervjuer samt litteraturstudier. De senare har använts för att få inblick i ämnet ITS och tjänster som finns eller är under utveckling inom området. Intervjuerna gjordes med personer som endera arbetar med forskning inom ITS eller är verksamma inom området samt med funktionshindrade bilförare. En kartläggning av tjänster har skett och resultatet av intervjuerna pekar på att det finns ett behov av ITS-tjänster för funktionshindrade bilförare. Delvis finns behov av tjänster som redan finns i dag, till exempel navigationssystem. Det finns även behov av andra tjänster som är under utveckling. Gemensamt för dessa tjänster är att de i vissa fall skulle behöva anpassas till de funktionshindrade med röstanpassning eller andra specifika anpassningar.

Resumo: Este estudo trata das políticas públicas para a Educação Infantil e seu principal objetivo foi analisar as políticas públicas de Educação Infantil desenvolvidas pela Secretaria Municipal de Educação (SEMED) de Porto Velho/RO, no período de 1999 a 2008. Caracteriza-se como estudo de abordagem qualitativa, com análise de dados qualitativos e quantitativos. Utiliza como fonte de dados a pesquisa documental, a entrevista individual e Grupo Focal. Os sujeitos colaboradores foram gestores da SEMED e professoras de escolas de Educação Infantil que atuaram no período em estudo. Também colaboraram com a pesquisa professoras que coordenaram a Educação Infantil no período de 1970 a 1990, no âmbito da SEDUC e SEMED. O estudo considera o acesso à Educação Infantil como fundamental para a garantia do desenvolvimento pleno da criança. Observa que o lugar de direito à educação já foi conquistado desde a Constituição Federal de 1988 e que outros instrumentos legais vem garantindo esse direito às crianças menores de seis anos. Os dados evidenciam que o atendimento à Educação Infantil na rede municipal de Porto Velho ocupou diferentes lugares no período de 1999 a 2008, tanto no discurso quanto na efetivação de ações, dependendo da gestão e do contexto. Verifica que de 1999 a 2004 a educação infantil foi colocada em um lugar de menor valor dentro das políticas educacionais municipais. Nesse período foram poucas as ações na área de formação, ampliação da rede e melhoria da infraestrutura das escolas. De 2005 a 2008 a educação infantil ocupou lugar de destaque nas ações da SEMED e foi considerada prioridade, com investimento financeiro superior ao do período anterior.

Abstract:

Nowadays, information technology outsourcing (ITO) represents an established business practice in which a considerable number of companies are involved. Since the success of ITO is highly dependent on the exposure to ITO risks, studying the very risks is of great importance. The aim of this thesis consists in revealing the occurrence of specific ITO risks: supplier lock-in, hidden costs and the loss of control over outsourced IT. Further aims of this work are the revelation of measures which can be taken in order to face these risks and of the influences these risks have on backsourcing considerations. The first part of this thesis constitutes the theoretical framework which is based on the review of relevant literature. Within this part of the work, transaction cost theory and resource-based theory are presented and applied for the discussion of the specific ITO risks under consideration. Furthermore, a multidimensional approach is utilized in order to illustrate the various dimensions of ITO. By this means, the identification of situations in which the ITO risks under consideration appear is enabled. The empirical part of this exploratory research is based on a multiple case study. The data necessary for this qualitative research was gathered from telephone interviews conducted with both ITO clients and IT suppliers. The results of this study indicate that the ITO risks under consideration all pose considerable threats to ITO operations and that there are both internal and external measures ITO companies can take in order to face these risks. Furthermore, the risks under discussion influence backsourcing considerations.

O presente relatório de estágio curricular de Mestrado Integrado em Medicina Veterinária está dividido em três partes. A “Parte I” que corresponde ao relatório de atividades desenvolvidas durante o estágio no Hospital Veterinário do Restelo - HVR, durante o período de três de Setembro de 2012 a 28 de Fevereiro de 2013, sob co- orientação do Dr. Jorge Cid. Na “Parte II” é feita uma revisão bibliográfica sobre as infeções de trato urinário-ITU, em felinos e na “Parte III” é então feita a caracterização da atividade de pesquisa desenvolvida no mesmo hospital. A ITU é definida como a afeção temporária ou permanente nas defesas do organismo, permitindo assim a adesão, multiplicação e persistência dos microrganismos neste sistema. As ITU’s podem ser classificadas segundo a sua localização, em superior ou inferior ou quanto à presença de fatores de risco, em complicada ou não complicada. Segundo o nosso estudo, as ITU’s possivelmente estão a ser sub-diagnosticadas, o género feminino é o mais afetado, surgem mais frequentemente em felinos geriátricos e os sinais clínicos poderão ser um pouco diferentes dos clássicos de trato urinário. Os agentes etiológicos mais isolados foram a E. coli e o Staphylococcus intermedius. As alterações características na análise de Urina Tipo II nem sempre se verificaram na presença de ITU’s, pelo que é assim essencial a realização da urocultura e respetivo teste de sensibilidade aos antibióticos-TSA, de forma a dirigir a terapêutica consoante o agente, o tipo de infeção e o organismo hospedeiro; ### Abstract- Characterization of Urinary Tract Infections in Cats This report traineeship of Master in Veterinary Medicine is divided into three parts. In "Part I" corresponds to the report of the activities undertaken during the internship at the Restelo Veterinary Hospital – HVR, during the period from 3 September 2012 to 28 February 2013, under the co-direction of Dr. Jorge Cid. In "Part II" is made a literature review on urinary tract infections-UTI, in cats and "Part III" is then made to characterize the research activity developed in the same hospital. The UTI is defined as a temporary or permanent breach in host defense mechanisms allowing adhesion, multiplication and persistence of the virulent microbes in the urinary tract. UTI’s can be classified according to their location, in upper or lower or for the presence of the risk factors, in uncomplicated or complicated. According to our study, the UTI’s possibly is being under diagnosed, the female gender is the most affected, occurs more often in geriatric cats and the clinical signs may be slightly different from the classic of the urinary tract. The etiologic agents isolated were E. coli and Staphylococcus intermedius. The characteristic changes in the urinalysis type II aren’t always observed in the presence of UTI, it is therefore essential for the realization of the respective urine culture and antimicrobial susceptibility testing, in order to plan the therapeutic according to the agent, to the type of infection and to the host organism.

Resumo: O trabalho propõe uma concepção dos direitos humanos em perspectiva existencial. Os direitos humanos são considerados um modo de ser do homem, ou, ainda, um produto da condição existencial da realidade humana. A partir da projeção das categorias e conceitos das filosofias da existência de Jean-Paul Sartre e Albert Camus no plano jurídico, o estudo promove uma nova compreensão da dignidade humana, assim como do sentido, da finalidade, da legitimidade e da gênese histórica dos direitos do homem, como também da teoria do direito subjetivo e até da teoria da justiça, com repercussões na própria ontologia jurídica, porquanto o direito passa a ser visto como uma praxis da liberdade e uma praxis para a liberdade. Arrimada no pensamento de Sartre e Camus, a pesquisa enfatiza a responsabilidade existencial dos juristas na construção dos direitos humanos, após denunciar os artifícios imanentes às fundamentações tradicionais desses direitos - seja ela jusnaturalista, para quem os direitos são descobertos, seja ela juspositivista, para quem os direitos são aplicados -, que se mostram funcionais para que eles absurdamente não sejam direitos propriamente ditos e não estejam em ação

Abstract:

Com a padronização das redes óticas passivas, em particular do GPON (gigabit-capable passive optical network) adotada no Brasil, uma nova gama de serviços passou a ser viável, dentre eles a transmissão de canais de TV para assinantes usando o protocolo IP (Internet protocol), sistema conhecido como IPTV. Este processo apresenta inúmeras vantagens, dentre elas a possibilidade de um número maior de canais e com qualidade variável. O grande inconveniente neste sistema é que em qualquer sistema de transmissão de TV digital o tempo de troca de canais, conhecido como tempo de zapping, pode chegar a alguns segundos. Para reduzir este problema, este trabalho descreve um processo de codificação e transmissão de IPTV em redes GPON que reduz o tempo de zapping, podendo chegar ao tempo de recuperação de um quadro (frame). O estudo foi baseado na codificação escalável em qualidade (SNR, signal to noise ratio) proposta no padrão MPEG-2 (Moving Picture Experts Group) e pode ser facilmente portado para outros padrões de codificação como os FGSs (fine grain scalability) do MPEG-4. O transporte utiliza a característica multicast das redes GPON além do protocolo IGMP (Internet group management protocol). Uma vez que o sistema IPTV propicia ao assinante vantagens como, o aumento do número de canais e a melhoria da qualidade de cada um deles devido à flexibilização da banda, este trabalho pressupõe que o assinante aceitará uma qualidade de vídeo inferior, no momento do zapping, desde que aumente com o decorrer do tempo. O aumento da qualidade é ilustrado por curvas comparativas, que mostram os tempos entre a mudança do canal, a entrada dele em baixa resolução e a melhora progressiva até a estabilidade em qualidade máxima.
With the standardization of passive optical networks, in particular GPON (gigabit-capable passive optical networks), which is adopted in Brazil, a new range of services become feasible, among them TV channels transmission to subscribers using the IP (Internet protocol), known as IPTV system, is one of the most important. This process has many advantages, including the possibility of offering a greater number of channels with variable quality. The greater inconvenience of this solution is that in any system of digital TV transmission the time to exchange channels, known as zapping time, can reach some seconds. To reduce this problem, this M.Sc thesis proposes a coding and transmission process for IPTV in GPON networks that reduces the zapping time to values smaller than one frame time. This work is based on the scalable SNR (signal to noise ratio) proposed in MPEG-2 standard and can be easily ported to other standards like FGS (fine grain scalability) in MPEG-4. Transport uses GPON multicast characteristics beside IGMP (Internet group management protocol). Once IPTV system offers many advantages like, increasing number of channels and better image quality per channel since bandwidth can be flexible. It is assumed that the IPTV subscriber will accept low video quality, at the zapping moment, but quality will increase progressively. Comparative graphics show the quality increase in terms of time between zapping, low quality video starting and the progressive quality increase up to stability in full quality.

Abstract:

This paper offers an existence result for finite dimensional stochastic differential inclusions with maximal monotone drift and diffusion terms. Kravets studied only set-valued drifts in [5], whereas Motyl [4] additionally observed set-valued diffusions in an infinite dimensional context. In the proof we make use of the Yosida approximation of maximal monotone operators to achieve stochastic differential equations which are solvable by a theorem of Krylov and Rozovskij [7]. The selection property is verified with certain properties of the considered set-valued maps. Concerning Lipschitz continuous set-valued diffusion terms, uniqueness holds. At last two examples for application are given.

Trichoderma are anamorphic fungi belonging to the class of Hifomicetos, also called imperfect fungi, or asexual conidial and whose gender Hypocrea teleomorph. They are free-living fungi, distributed throughout the world and found in different soil temperatures, especially those containing organic matter. Usually are not considered important human pathogens, but there are some reports indicating occasional pathogenicity of some species. Its easy handling and in vitro, stability and viability of colonies preserved this kind are a big target for biotechnology research. Because of these characteristics were isolated Trichoderma from plant Victoria amazonica, Rollinia sp. Murraya paniculata and Strychnos cogens; wood Scleronema micranthum, known as cardeiro; jatoba (Hymenaea courbaril), land of cubiu culture (Solanum sessiliflorum) and Indian black earth, in order to identify the molecular biology, the species level, such isolates and to assess their ability to produce cellulolytic enzymes. Of the 30 lines obtained were cultured spore, which were preserved in mineral oil, Castellani and method in 10% glycerol. From the suspension in glycerol, each sample was inoculated in 20ml of 10μL BD and cultivated 26oC, 100 rpm for 40:00 h. Next was extracted genomic DNA, performed PCR of specific regions of the ITS-1 and ITS-2 ribosomal DNA sequencing and subsequently. For the production of enzymes, the isolates were first grown in induction medium. Were inoculated 10μL of spore solution (glycerol 10%) in 50 mL of solution Manachini where the substratum was used to carboxymethylcellulose. The fungi were incubated at 27 ° C, 120 rpm for 120 hours. The dosage of CMCase was performed using the method of acid Dinitrosalicílico. For the determination of β-glucosidase was used p-nitrophenyl-β-D-glucopyranoside (PNPG) as substrate for the enzyme. The total protein concentration was determined by the Bradford method, using the reagent concentrate commercial Bio-RadTM and bovine serum albumin (ASB) as standard. The result of molecular identification of the first 13 samples revealed the species: T. harzianum, T. koningii, T. asperellum, T. viride, T. ovaslisporum, T. hamatum, T. piluliferum and T. koningiopsis, with a percentage between 96 and 99% identity and 100% reliability. The results indicated CMCase enzyme to low values, less than 0.100 U / mL with the exception of T. koningii (MPCE 10 3.2), T. harzianum (MPCE 2 2.2a), both isolates of M. paniculata, and isolate 1437 identified as Trichoderma sp., from Indian black earth, which showed slightly higher levels of 0.112 and 0.103 and 0.105 U / mL, respectively. For β-glucosidase, the results showed high activity in the vast majority of isolates with emphasis on T. harzianum MPCE 3 3.1 (10.45 U / mL) and T. piluliferum Vrc 2 3.2 (9.71 U / mL). All isolates produced protein in culture medium containing carboxymethylcellulose as substrate inducer
Trichoderma são fungos anamórficos pertencentes à classe dos hifomicetos, também chamados fungos imperfeitos, assexuais ou conidiais e que têm como teleomorfo o gênero Hypocrea. São fungos de vida livre, distribuídos em todo o mundo e encontrados em solos de diversas temperaturas, especialmente naqueles que contém matéria orgânica. Geralmente não são considerados importantes patógenos humanos, mas existem alguns relatos indicando patogenicidade ocasional em algumas espécies. Sua fácil manipulação e cultivo in vitro, estabilidade e viabilidade das colônias preservadas, fazem desse gênero um grande alvo para as pesquisas biotecnológicas. Por tais características, foram isolados Trichoderma das plantas Victoria amazonica, Rollinia sp., Murraya paniculata e Strychnos cogens; da madeira Scleronema micranthum, conhecida como cardeiro; de jatobá (Hymenaea courbaril), do solo de cultura de cubiu (Solanum sessiliflorum) e de terra preta de índio, com o objetivo de identificar, pela biologia molecular, em nível de espécie, tais isolados, bem como avaliar sua capacidade de produção de enzimas celulolíticas. Das 30 linhagens obtidas foram realizadas culturas monospóricas, as quais foram preservadas em óleo mineral, método Castellani e em glicerol 10%. A partir da suspensão em glicerol, de cada amostra foi inoculado 10μL em 20mL de BD e cultivado a 26oC, a 100 rpm por 40:00h. Em seguida foi extraído o DNA genômico, deste realizada a PCR específica para as regiões ITS-1 e ITS-2 do DNA ribossômico e posteriormente o sequenciamento. Para a produção de enzimas, os isolados foram previamente cultivados em meio indutor. Foram inoculados 10μL da solução de esporos (Glicerol 10%) em 50mL de solução de Manachini onde o substrato indutor utilizado foi a carboximetilcelulose. Os fungos foram incubados a 27°C, 120 rpm durante 120 horas. A dosagem de CMCase foi efetuada com base no método do Ácido Dinitrosalicílico. Para a dosagem de β-glucosidase foi utilizado o pnitrofenil- β-D-Glucopiranosídeo (pNPG) como substrato para a enzima. A concentração de proteínas totais foi determinada pelo método de Bradford, utilizando-se o reagente concentrado comercial da Bio-RadTM e albumina de soro bovino (ASB), como padrão. O resultado da identificação molecular das primeiras 13 amostras nos revelaram as espécies: T. harzianum, T. koningii, T. asperellum, T. viride, T. ovaslisporum, T. hamatum, T. piluliferum e T. koningiopsis, com um percentual entre 96 e 99% de identidade e 100% de confiabilidade. Os resultados enzimáticos para CMCase indicaram valores baixos, inferiores a 0,100 U/mL com exceção de T. koningii (MPCe 10 3.2), T. harzianum (MPCe 2 2.2a), ambos isolados de M. paniculata, e o isolado 1437 identificado como Trichoderma sp., proveniente de terra preta de índio, que apresentaram valores um pouco mais altos de 0,112 e 0,103 e 0,105 U/mL, respectivamente. Para β-glucosidase, os resultados apresentados mostraram alta atividade na grande maioria dos isolados com destaque para T. harzianum MPCe 3 3.1(10,45U/mL) e T. piluliferum Vrc 2 3.2 (9,71 U/mL).

Abstract:

O gênero Brasiliorchis inclui atualmente 14 espécies de orquídeas restritas ao bioma Mata Atlântica, ocorrendo desde Misiones, Argentina, até o Estado da Bahia, na região nordeste do Brasil.Embora estas espécies tenham sido tradicionalmente reconhecidas pelos seus caracteres vegetativos e principalmente florais, elas são morfologicamente muito similares e apresentam caracteres diagnósticos contínuos,assim, ousoexclusivo da morfologiapode não ser útil para identificação das espéciesneste grupo de orquídeas. Um estudo morfométrico anteriormente realizado com seis espécies deste gênero não conseguiu identificar agrupamentos claros. Amaioria dos caracteres analisados apresentou sobreposição entre diferentes espécies, sendo que apenas a espécie B. gracilisse mostrou distinta das demais. O objetivo desse estudo foi contribuir para aidentificação de linhagens evolutivamente distintas dentro do gênero e avaliar se os padrões filogenéticos de diversificação corroboram com o estudo morfométrico anteriormente realizado.Foram utilizados dados de sequências de plastídios (psbj-petA, atpl-atpH)e nucleares (ITS1-2) considerandoampla variação geográfica e morfológica observada no grupo. Foram amostrados 96 indivíduos,originados de 37 localidades de ocorrência no Brasil, incluindo 11 espéciesdo gênero. Análises de máxima parcimônia e bayesiana foram realizadas considerando os dados separadamente e concatenados.Os resultados suportam B. schunkeana como irmã de todas as outras espécies do gênero. B. barbozaefoi reconhecida como um grupo monofilético distinto, corroborando com os caracteres morfológicos diagnósticos desta espécie, e possivelmente irmão das espécies do complexo B. picta.A espécie B. gracilis não foi reconhecida como um grupo monofilético, não corroborando com o estudo de morfometria, na qual essa espécie se apresentou distinta das outras do complexo. Contudo, nas análises concatenadas alguns indivíduos apresentaram-se como irmãos das espécies do complexo B. picta. As espécies morfologicamente homogêneas pertencentes ao complexo B. picta (B. chrysantha, B. marginata, B. porphyrostele, B. ubatubana, B. phoenicanthera e B. picta) não formaram clados monofiléticos distintos. B. kautskyi e B. consanguinea, as quais são morfologicamente distintas, foram incluídas nos clados constituídos pelas espécies do complexo B. picta.Eventos de introgressão e hibridação podem ser potenciais causas da insuficiente resolução das árvores filogenéticas obtidas nesse estudo. Os padrões observados também sugerem que a separação das linhagens pode ter ocorrido recentemente e/ou rapidamente. Marcadores adicionais e análises de árvores de espécies podem ajudar a esclarecer os padrões de diversificação neste grupo.
The genus Brasiliorchis currently includes 14 species of orchids occurring mainly in the Atlantic Forest Biome, from Misiones, Argentina, to the stateof Bahia, in northeastern Brazil. Although these species have been traditionally recognized by vegetative andmainly floral traits, they are morphologically very similar and display continuouscharacters, thus the exclusive use of the morphologycannot be useful for species identificationin this group of orchids. A morphometric study previously conducted with six species of this genus could not identify clear groupings. The majority of analyzed characters showed overlap between different species, with only the species B. gracilisbeing distinct from the others. The goals of this study were to contribute to the identification of evolutionary distinct lineages within the genus and assess if the phylogenetic patterns of diversification agree with a previous morphometric study available. Sequence data from plastid (psbj-petA, atpl-atpH) and nuclear (ITS1-2)regions were used considering wide morphological and geographical sampling variation. We sampled 96 individuals, originated from 37 sites of occurrence in Brazil, including 11 species of the genus. Bayesian and parsimony analyses were performed considering data separately and concatenated. The results support B. schunkeana as sister to all other species of the genus. B. barbozaewasrecognized as a monophyletic group,corroborating with morphological diagnostic characters of this species,and possibly sisters of the complex species B. picta.The species B. gracilis was not recognized as a monophyletic group, not agreeing with the morphometry study, which showed this species as being distinct from the other species in the complex. However, in the concatenated analysis, some individuals presented themselves as sisters of the species complex B. picta. The morphologically homogeneous species belonging to the B. picta complex (B. chrysantha, B. marginata, B. porphyrostele, B. ubatubana, B. phoenicanthera e B. picta) did not form distinct monophyletic clades. B. kautskyi and B. consanguinea, which are morphologically clearly distinct, are embedded in clades consisting of the B. pictaspecies complex.Hybridization and introgression events may be potential causes of insufficient resolution of phylogenetic trees obtained in this study. The observed patterns also suggest that the separation of the lineage may have occurred recently and/or quickly.Additional markers and species tree analyses may help clarify diversification patterns in this group.

Abstract:

From the remarks made by the then Secretary General of ITU, one envisions the possibilities of a truly connected world and upholding of tenets prescribed in the Outer Space Treaty of 1967, which provides for all of outer space, including the Geostationary orbit, as the province of all mankind, to be used for the benefit and in the interests of all countries, irrespective of their degree of economic or scientific development.2 On the backbone of ‘connecting the world’ is the scarce resource, spectrum, which is managed and allocated to states by the International Telecommunications Union (ITU). The demand for radio-based applications has been growing in line with the increasing mobility across the globe. Radio spectrum is a major global asset contributing substantial value to economies of states, whether big or small, and underlines critical aspects of their citizens’ lives. Radio communications is critical to areas such as air travel, emergency services, telecommunications, sound and television broadcasting, military defence, space research and other scientific activities Spectrum plays a very critical role in the economic development of any society as it brings connectivity, it even plays a critical role in developing economies as it serves in bridging the existing “digital divide”. However, this precious commodity is a scarce resource, the available radio spectrum is limited.4 The rapidly changing environment of electronic communications, impressive technological progress, convergence and changing habits of end-users’ consumption is creating pressure for existent spectrum as well as its regulation and management. This has necessitated the need for managing a new, previously unused, international resource – the satellite spectrum/orbit., which is becoming increasingly crowded. At the same time, the increasing use of lower Earth orbits is further increasing the need for international coordination. ITU plays a crucial role in ensuring that operators’ multimillion dollar satellite systems operate smoothly throughout their lifetimes, delivering services to billions of people without interfering with each other. The space-faring states are demanding more spectrum as they increase activities in outer space due to technological advancements, however, at what cost to the non-space faring states. At the same time the ITU is burdened with the responsibility of trying to harmonise the use of spectrum bands across the globe between the space-faring and upcoming non-space faring states, mainly the developing countries. The objective of this research is to ascertain whether, given the rapid technological changes being experienced across the globe, the ITU is still sufficient in its current state, to adequately manage and regulate the allocation of spectrum to all states, maintaining the true spirit of the principle of ‘province of all mankind’. Bearing in mind the ever increasing demands of advanced economies over the gradually increasing demands of developing economies and the concept of geostationary orbit being for the benefit of all countries irrespective of their degree of economic or scientific development. countries’. It is against this background that this thesis seeks to address the following question “The role of the International Telecommunications Union in Outer Space Spectrum management with respect to developing nations”. The author will tackle this research through a quantitative lens, making use of the desktop methodology because of the nature of the research topic. A significant amount of reading will need to be done around the legal framework governing the ITU with regards to space technology. This thesis is mainly based on secondary data, retrieved from official documents, reports, news articles, academic papers and books. The research will take upon the characteristics of being critical to current legislative frameworks as well as the role of the ITU in the management and allocation of spectrum. It will be essential for the author to look at the historical legislature and how it has gradually progressed into what is currently obtaining. The thesis will take a critical approach in order to interrogate the relevance of the ITU in today’s modern era in light of the provisions of the Outer Space Treaty and the various ITU regulations particularly the ITU Convention; ITU Constitution and the ITU Radio Regulations in spectrum management and allocation including the position of developing states.

Abstract:

Le nombre de véhicules connectés augmentent et pour une utilisation plus intelligente des systèmes de transport, les véhicules ont besoin d’accroître leur connaissance de l’environnement. Cela peut être atteint en permettant aux véhicules de communiquer avec leur environnement. Pour une connectivité omniprésente, il sera nécessaire d’utiliser diverses technologies sans fil, existantes. Dans un tel environnement de réseau d’accès hétérogène, il est nécessaire de fournir aux applications des mécanismes décisionnels transparents pour gérer l’affectation des flux de données sur les réseaux disponibles. Dans cette thèse, nous proposons le Ant-based Decision Maker for Opportunistic Networking (AD4ON), un Decision Maker (DM) mécanisme modulaire capable de choisir le meilleur profil de communication disponible pour chaque fluxde données dans un environnement de réseau hétérogène et dynamique. Le mécanisme proposé gère les exigences et préférences de différents acteurs (applications, utilisateurs,etc.), ainsi que les information réseaux dans un futur proche, afin de prendre des décisions plus intelligentes. C’est-à-dire, afin d’augmenter la satisfaction de chaque acteur impliqué dans le processus de communication, ainsi que d’augmenter la stabilité de la décision (par exemple, en réduisant l’effet “ping-pong“)
Demand from different actors for extended connectivity where vehicles can exchange data with other devices have pushed vehicle manufacturers to invest in embedded solutions, which paves the way towards Cooperative Intelligent Transportation Systems (C-ITS). Cooperative vehicles enable the development of an ecosystem of services around them. Due to the heterogeneousness of such services and their specific requirements, for ubiquitous connectivity it is necessary to combine existing wireless technologies, providing applications with a communication architecture that hides such underlying access technologies specificities. Moreover, due to vehicles’ high velocity it is needed a Decision Maker (DM) mechanism capable to take into account the short-term prevision about network environment in order to better manage all flow communications. Based on the Intelligent Transportation Systems (ITS) architecture proposed by International Organization for Standardization (ISO), we proposed the Ant-based Decision Maker for Opportunistic Networking (AD4ON), a modular decision maker mechanism capable to choose the best available access network for each data flow in an heterogeneous and dynamic network environment. The proposed mechanism manages requirements and preferences from different actors, taking into account the short-term prevision about the network environment. Simulations have demonstrated that the AD4ON outperforms current benchmark algorithms, by increasing decision’s stability, reducing the “ping-pong” effect and maximizing flow’s satisfaction. Moreover, we demonstrate that taking into account the short-term prevision, the AD4ON can optimize the algorithm reaction time

Resumo: A educação literária, nas escolas e universidades, enfrenta inúmeros problemas, e o principal é a falta de motivação profunda dos alunos. Ortega y Gasset dizia que todo estudo que não se funda num interesse vital é uma falsidade, e essa é a situação geral do ensino massificado da nossa época. A escola e a universidade se transformaram enormemente nos últimos séculos, passando a atender outros propósitos, como a preparação profissional e a modelagem de atitudes e mentalidades em vista de objetivos políticos. As humanidades, por sua vez, foram tomadas por uma onda de estudos críticos que combatem a autoridade da Tradição e dos valores que fundaram a nossa civilização. A crise da educação é, no fundo, uma crise muito maior, na qual o homem perdeu a fé nos valores que edificaram o Ocidente, sem que pudesse encontrar um centro em que reconhecesse a si mesmo e pudesse ordenar a massa de informações e conhecimentos que a nossa época produz em abundância. Não há, porém, alternativas que não emerjam diretamente da Tradição, ou melhor, das tradições que a Tradição oferece. Devemos conhecê-las para escolher aquelas que nos servem, para fazer "o exame do moderno em face do eterno" (CARPEAUX, 1999, p. 203). É nisso que consiste a Educação Liberal, que se baseia no estudo dos clássicos - especialmente as obras literárias - pois a literatura é a base na qual se fundam as culturas e os outros tipos de conhecimentos. Ela pode nos auxiliar a suprir as deficiências de uma educação utilitarista, guiando-nos na busca da sabedoria e da realização do sentido da vida; em suma, de um novo estilo humano de existência
Astratto: L'educazione letteraria, nelle scuole e università, si trova ad affrontare oggi innumerevoli difficoltà, soprattutto a causa di un grande contingente di alunni senza interesse negli studi. Ortega y Gasset credeva che ogni studio non motivato da un interesse vitale fosse una falsità, e questo è il caso di molti alunni della scuola di massa che, negli ultimi secoli, si è trasformata profondamente, diffondendosi ampiamente e proponendosi come valido ausilio per la formazione professionale e l'Ingegneria Sociale. Le scienze umane, dall'altra parte, sono state fortemente influenzate da un'ondata di studi critici che hanno messo in difficoltà l'autorità della Tradizione e dei valori fondanti della nostra civiltà. La crisi dell'educazione è, in fondo, il risultato di una crisi ancor maggiore, dentro la quale l'uomo ha perduto la fede nei valori, su cui ha edificato la propria cultura. Ora il suo compito è trovare una propria centralità in questo universo confuso in cui riconoscere se stesso e poter ordinare l'ammasso di informazioni e conoscenze che la nostra epoca continua a produrre abbondantemente. Non ci sono alternative che non emergano direttamente dalla Tradizione, anzi diciamo pure dalle tradizioni che la Tradizione stessa ci offre. Dobbiamo conoscerle per poter scegliere quelle che ci servono, per realizzare "l'esame del moderno in faccia all'eterno" (CARPEAUX, 1999, p. 203). Questo è l'obiettivo dell'Educazione Liberale, basata sullo studio dei classici - specialmente delle opere letterarie - poiché la letteratura è la base su cui si edificano le culture e tutti i tipi di discorsi e conoscenze umane. Essa può aiutarci a vincere le deficienze di un'educazione utilitaristica, guidandoci nella ricerca del Sapere e del senso della vita; insomma, di un nuovo stile di esistenza

Abstract:

Intelligent Transportation Systems (ITS) have attracted an increasing amount of attention in recent years. Thanks to the fast development of vehicular computing hardware, vehicular sensors and citywide infrastructures, many impressive applications have been proposed under the topic of ITS, such as Vehicular Cloud (VC), intelligent traffic controls, etc. These applications can bring us a safer, more efficient, and also more enjoyable transportation environment. However, an accurate and efficient traffic flow prediction system is needed to achieve these applications, which creates an opportunity for applications under ITS to deal with the possible road situation in advance. To achieve better traffic flow prediction performance, many prediction methods have been proposed, such as mathematical modeling methods, parametric methods, and non-parametric methods. It is always one of the hot topics about how to implement an efficient, robust and accurate vehicular traffic prediction system. With the help of Machine Learning-based (ML) methods, especially Deep Learning-based (DL) methods, the accuracy of the prediction model is increased. However, we also noticed that there are still many open challenges under ML-based vehicular traffic prediction model real-world implementation. Firstly, the time consumption for DL model training is relatively huge compared to parametric models, such as ARIMA, SARIMA, etc. Second, it is still a hot topic for the road traffic prediction that how to capture the special relationship between road detectors, which is affected by the geographic correlation, as well as the time change. The last but not the least, it is important for us to implement the prediction system in the real world; meanwhile, we should find a way to make use of the advanced technology applied in ITS to improve the prediction system itself. In our work, we focus on improving the features of the prediction model, which can be helpful for implementing the model in the real word. Firstly, we introduced an optimization strategy for ML-based models' training process, in order to reduce the time cost in this process. Secondly, We provide a new hybrid deep learning model by using GCN and the deep aggregation structure (i.e., the sequence to sequence structure) of the GRU. Meanwhile, in order to solve the real-world prediction problem, i.e., the online prediction task, we provide a new online prediction strategy by using refinement learning. In order to further improve the model's accuracy and efficiency when applied to ITS, we provide a parallel training strategy by using the benefits of the vehicular cloud structure.

Fungos endofíticos são micro-organismos que habitam o interior da planta hospedeira, sem causar danos aparentes ou estruturas externas visíveis. O coqueiro (Cocos nucifera L.) é uma espécie tropical, largamente distribuída na Ásia, África, América Latina e regiões do Pacífico, sendo o Brasil o quarto maior produtor mundial. Devido à importância agroeconômica do coco, este trabalho teve por objetivo determinar a micobiota endofítica de folhas sadias de C. nucifera em duas cultivares (Anão-amarelo e Anão-verde) e um híbrido (PB 121) em Goiana, Pernambuco. No laboratório, fragmentos de raque e folíolo foram lavados com água corrente e sabão neutro, e com auxílio de um furador esterilizado foram feitos discos foliares (6 mm), posteriormente desinfestados em álcool 70% por 1 minuto, em hipoclorito de sódio (NaOCl) a 2% por 2 minutos e 30 segundos, em álcool 70% por 30 segundos e finalmente duas lavagens com água destilada esterilizada. Os fragmentos foram tranferidos para placa de Petri, em triplicata, contendo Batata-Dextrose-Ágar (BDA) acrescido de cloranfenicol (50 mg.L-1). Foram sequenciados a região ITS do rDNA dos isolados e em seguida verificada a similaridade Blastn e realizada análises filogenéticas. Índices de diversidade, curva de acumulação de espécies, similaridade e frequência de ocorrência foram calculados. O total de 1296 fragmentos de folhas/raques foram analizados e 474 espécimes de fungos endofíticos foram isolados e distribuídos em 31 gêneros e 37 espécies. A espécies identificadas são representantes do filo Ascomycota, pertencentes às classes Sordariomycetes, Dothideomycetes e Eurotiomycetes, além de Occultifur externus, Rhodotorula marina e Pseudozyma hubeiensis anamorfos do filo Basidiomycota e Syncephalastrum racemosum do filo Zygomycota. Arthrinium xenocordella, Ascotricha guamenses, Phlyctaeniella sp., Pyrenochaetopsis decipiens, P. leptospora e Stenella musae são citadas pela primeira vez como endofíticos. Fusarium proliferatum, F. solani e Paecilomyces lilacinus são reportadas pela primeira vez como endofíticos em Cocos nucifera.
