Esta tese procura reflectir sobre as possibilidades de constituição de uma colecção de arte colonial portuguesa (objectos artísticos híbridos resultantes da experiência ultramarina portuguesa) (Young 1995; Bhabha 2004) no contexto dos museus nacionais de arte. Recorrendo ao património da Igreja Católica em Portugal (especificamente, ao do Patriarcado de Lisboa), circunscreveu-se a análise das peças ao período Moderno. Considerando que não existem em Portugal colecções de âmbito museológico com a classificação de colonial, procurei no vasto património móvel da diocese de Lisboa (algum dele in situ e a uso) a aplicação dos parâmetros que constituiriam tal sistema (Baudrillard 1978; Foucault 1977 e 1988). A organização deste trabalho baseou-se em dois vectores fundamentais: um conceptual e metodológico que procura nos estudos teóricos e nos instrumentos da museologia as ferramentas para, primeiro, a constituição da colecção e, depois, a fundamentação documental e analítica da mesma (Impey e MacGregor 1989; Pearce 1994; Elsner e Cardinal 1997). E um segundo vector, que procura na historiografia do termo mais recuado e gregário, o “indo-português”, a fundamentação para a problematização em torno da questão mais vasta da introdução de artefactos de origem colonial na classificação de arte de acordo com os parâmetros europeus. Neste sentido, procura-se perceber como foram os artefactos coloniais recebidos – já que desde o início lhe foram conferidos valores de etnicidade –, interpretados – como “portugueses” – e (re)classificados como arte no âmbito da realização das exposições internacionais e da criação dos museus nacionais de arte. Por último, através da aplicação da ferramenta de inventário utilizada pela Rede Nacional de Museus, o Matriz3.0, a uma amostra de estudo (sete fichas de inventário correspondentes a sete casos de estudo), desenvolve-se a abordagem à ideia do inventário enquanto instrumento (isto é, a documentação de peças de arte colonial portuguesa através de um sistema criado para a arte europeia), que se propõe servir de base à narrativa da ideia de que a ferramenta inventário é o primeiro passo do(s) discurso(s) elaborado(s) sobre o objecto (dos quais fazem parte as biografias da vida cultural dos objectos) (Appadurai 2011). Problematizando este tema através de cinco v campos da ficha de inventário – “As Categorias e o Número de Inventário”; “A difícil atribuição de Autorias e a múltipla Produção”; “A Datação por aproximação”; “A Informação Técnica” e “O campo infinito da Documentação Associada” –, do acrescento de um parâmetro especificamente desenvolvido no âmbito da arte colonial – “As funções dos objectos” – e colocando em evidência a importância da análise destas peças a partir dos aspectos inerentes à sua materialidade (Miller 2005), propõe-se como resposta ao enunciado colocado no início deste resumo e possibilidades expositivas, que não é tanto o sistema de classificação que está implícito à institucionalização do objecto (ou seja, a forma como o social categoriza as coisas) que condiciona o seu entendimento, mas mais os discursos que são produzidos sobre ele (isto é, a forma como o social representa as coisas) (Vergo 2000; Macdonald 2006; Semedo e Lopes 2006).

The object of this dissertation is the analysis of the legal framework applicable to contracts for provision of electronic communications services, while trying to offer solutions to some of the issues regarding this matter. The main focus of this study will be the rules concerning service’s suspension, which have been recently amended. The technological development and the establishment of these services as information transmitters and work tools were noteworthy for its growing importance at the present time. These services include cable television, telephone (landline and mobile) and internet and they are regulated by Law nr 23/96, July 26th, along with other essential public services. Said law sets a group of principles and duties, such as good faith (article 3), continuity and quality of the service (article 7) and the duty to rightfully inform the user (article 4), in order to protect the users. For the analysis of legal framework applicable to these particular contracts it is also fundamental to mention Law nr 5/2004, February 10th, known as Electronic Communications Law. The provisions regarding the service’s suspension are currently prescribed in articles 52.º and 52.º-A of the law. Given the amendments introduced by Law nr 10/2013, January 28th, consumers are subjected to a regulation different from the one applicable to the other users, established in the new article 52.º-A. From our analysis, we have concluded that the main change from past provisions has to do with the automatic termination of the contract as consequence of the consumer’s failure to pay the price or to conclude a written payment arrangement after service’s suspension.

The Common Tern (Sterna hirundo) is a ground nesting colonial seabird. Terns rely primarily on small prey fishes which they obtain through plunge diving for their survival as well as the survival of their offspring during the breeding season. The zebra mussel (Dreissena polymorpha) is a small bivalve mollusk that invaded North American waters in the late 1980's. Through its suspension feeding, the zebra mussel has the ability to alter the entire aquatic ecosystem, ultimately leading to a reduction in pelagic organisms including small prey fish. The objective of the study was to determine what (if any) indirect effects the invasion of the zebra mussel has had on fish prey captured by terns. The study took place in two separate two-year periods, 1990-91 and 1995-96 on a concrete breakwall off the north shore of Lake Erie near Port Colborne, Ontario. Daily nest checks revealed clutch initiation dates, egg-laying chronology, hatching success and morphological egg characteristics (length and breadth). Behavioural observations included time each sex spent in attendance with its brood, the frequency of feeding chicks and the prey species composition and size fed to chicks as well as to females (courtship feeding). Egg sizes did not differ between study periods, nor did feeding rates to chicks, suggesting that food was not a limiting resource. Terns spent less time with their broods (more time foraging) in the 1995-96 period. However, they also had significantly larger broods and fledged more offspring. The time of each individual foraging trip decreased, suggesting that fish were easier to obtain in 1995 and 1996. Lastly, kleptoparasitism rates decreased, suggesting that the costs of foraging (time, energy) actually decreased as fewer birds adopted this strategy to compensate for what I assumed to be a lack of available food (fish). The only significant difference between the periods of 1990, 1991 and 1995, 1996 was a change in diet. Terns delivered significantly fewer rainbow smelt and more emerald shiner in 1995 and 1996. However, the average size of fish delivered did not change. Thus, there was little impact on prey captured by Common Terns in Lake Erie since the invasion of the zebra mussel.

In this thesis, I explore how the folk-rock music of Ani DiFranco has influenced the activist commitments, sensibilities, and activities of reproductive rights activists. My interest in the relation of popular music to social movements is informed by the work of Simon Frith (1987, 1996a, 1996b), Rob Rosenthal (2001), and Ann Savage (2003). Frith argues that popular music is an important contributor to personal identity and the ways that listeners see the world. Savage (2003) writes that fans develop a unique relationship with feminist/political music, and Rosenthal (2001) argues that popular music can be an important factor in building social movements. I use these arguments to ask what the influence of Ani DiFranco's music has been for reproductive rights activists who are her fans. I conducted in-depth interviews with ten reproductive rights activists who are fans of Ani DiFranco's music. All ten are women in their twenties and thirties living in Ontario or New York. Each has been listening to DiFranco's music for between two and fifteen years, and has considered herself a reproductive rights activist for between eighteen months and twenty years. I examine these women's narratives of their relationships with Ani DiFranco's music and their activist experience through the interconnected lenses of identity, consciousness, and practice. Listening to Ani DiFranco's music affects the fluid ways these women understand their identities as women, as feminists, and in solidarity with others. I draw on Freire's (1970) understanding of conscientization to consider the role that Ani's music has played in heightening women's awareness about reproductive rights issues. The feeling of solidarity with other (both real and perceived) activist fans gives them more confidence that they can make a difference in overcoming social injustice. They believe that Ani's music encourages productive anger, which in turn fuels their passion to take action to make change. Women use Ani's music deliberately for energy and encouragement in their continued activism, and find that it continues to resonate with their evolving identities as women, feminists, and activists. My study builds on those of Rosenthal (2001) and Savage (2003) by focusing on one artist and activists in one social movement. The characteristics of Ani DiFranco, her fan base, and the reproductive rights movement allow new understanding of the ways that female fans who are members of a female-dominated feminist movement interact with the music of a popular independent female artist.

Exploring the new science of emergence allows us to create a very different classroom than how the modern classroom has been conceptualised under the mentality of efficiency and output. Working on the whole person, and not just the mind, we see a shift from the epistemic pillars of truth to more ontological concerns as regards student achievement in our post-Modern and critical discourses. It is important to understand these shifts and how we are to transition our own perception and mentality not only in our research methodologies but also our approach to conceptualisations of issues in education and sustainability. We can no longer think linearly to approach complex problems or advocate for education and disregard our interconnectedness insofar as it enhances our children’s education. We must, therefore, contemplate and transition to a world that is ecological and not mechanical, complex and not complicated—in essence, we must work to link mind-body with self-environment and transcend these in order to bring about an integration toward a sustainable future. A fundamental shift in consciousness and perception may implicate our nature of creating dichotomous entities in our own microcosms, yet postmodern theorists assume, a priori, that these dualities can be bridged in naturalism alone. I, on the other hand, embrace metaphysics to understand the implicated modern classroom in a hierarchical context and ask: is not the very omission of metaphysics in postmodern discourse a symptom from an education whose foundation was built in its absence? The very dereliction of ancient wisdom in education is very peculiar indeed. Western mindfulness may play a vital component in consummating pragmatic idealism, but only under circumstances admitting metaphysics can we truly transcend our limitations, thereby placing Eastern Mindfulness not as an ecological component, but as an ecological and metaphysical foundation.

L’étude proposée dans ce mémoire porte sur le processus de visite des adolescents de 14-16 ans au Musée des beaux-arts de Montréal. Je mobilise principalement les concepts de « médiateurs » et « médiations », entendus selon la définition proposée par Hennion (1988, 2000). En effet, Hennion propose de voir la médiation non comme un pont entre deux entités, vision commune de la médiation, mais comme un processus en construction. Ainsi, le médiateur est un élément qui va capter l’attention du jeune visiteur et la médiation est l’action qui va se développer dans cette relation médiateur-visiteur. L’analyse vise plus particulièrement à identifier les médiateurs qui agissent durant cette visite et à comprendre les médiations qui se mettent en place. Cette étude a été réalisée au moyen d’entrevues semi-structurées et d’observations participantes, auprès de six adolescents, âgés de 14 à 16 ans. Une première entrevue permettait de connaître les antécédents de ces jeunes à l’égard des musées et de comprendre suite à quelles mises en condition ils se rendaient à l’exposition. Une observation, par groupe de deux participants, a ensuite été menée lors de l’exposition du Musée des beaux-arts de Montréal : Il était une fois l’impressionnisme. Une histoire de l’impressionnisme : chefs-d’œuvre de la peinture française du Clark. Ces observations ont permis de repérer les moments qui ont capté l’attention des participants durant leur visite. Enfin, une seconde entrevue a été l’occasion de revenir sur leur expérience de visite et de dégager les médiations qui se sont mises en place. Sur les bases de ce terrain, ce mémoire met en avant un ensemble de médiateurs (les autres visiteurs, l’environnement physique, l’œuvre et le récit) et de médiations (rêver, comprendre, se projeter, admirer, comparer et refuser) qui se sont développées chez ces adolescents. Suite à cela, ce mémoire propose une explication du processus de visite tel qu’analysé chez ces adolescents à travers la représentation de la « spirale coquillage ». Cette représentation souligne le fait que le processus de visite n’est pas un phénomène linéaire mais se fait par la confrontation des antécédents de l’adolescent avec sa nouvelle expérience de visite. Il s’agit donc d’un processus circulaire qui se base sur ses antécédents pour construire progressivement de nouvelles strates, qui conditionneront ses prochaines expériences au musée.
