Esta dissertação apresenta o Percurso de uma Oficina realizada na Lomba do Pinheiro, em Porto Alegre. Com a participação de trabalhadores e usuários do Programa de Saúde da Família (PSF) Vila Viçosa constituiu-se como um desdobramento do Projeto de Pesquisa “Oficinando em Rede”, tendo como proposta a expansão de uma Oficina tecnológica a outros espaços da cidade. Atravessada pelas ações de pesquisa e extensão que constituem este Projeto, realizando Oficinas tecnológicas no Centro Integrado de Atenção Psicossocial (CIAPS) com a participação de jovens e trabalhadores, o interesse deste estudo foi despertado nas primeiras visitas da pesquisadora ao CIAPS quando de sua distinção a inscrições pelo corredor da instituição. Inscrições que, compreendidas neste estudo como marcas encarnadas em um espaço e tempo, constituem modos de viver/conviver. Interessada em analisar como a produção de inscrições pode explicitar redes de conversações e modular o conversar configurando novas distinções e emoções, tal questionamento resultou no objetivo desta pesquisa. Delineada como um estudo de natureza qualitativa, na perspectiva de uma pesquisa-intervenção, foi desenvolvida na realização de trajetos com o uso das TIC (tecnologias da informação e comunicação) por áreas de abrangência do PSF. Apresentando o Percurso como método indispensável à consolidação do trabalho possibilitou um operar performático no encontro com as inscrições naquele conversar que, em momentos de problematização coletiva, foram reconfiguradas nas inscrições de fotografia e vídeo. Constituída com o interesse dos participantes em conversarem com outras redes, a Oficina do Percurso possibilitou ações compartilhadas que em momentos de breakdowns abriu caminhos à cognição inventiva. / This dissertation presents the course of a workshop carried out in the Lomba do Pinheiro neighbourhood, in the city of Porto Alegre, RS, Brazil. Personnel and users of the Vila Viçosa Family‘s Health Programme participated in the workshop, which is part of the research project ‗Oficinando em rede‘ (Workshop on line). The main objective of such project is to expand technological workshops to other areas of the city. In addition, the workshop concept consists of ideas and actions originated during research and extension projects. As a result, a series of technological workshops were accomplished with the participation of young adults and workers at the Integrated Psychosocial Attention Centre (CIAPS) — where the interest of the present study originated. During my first visits to CIAPS, I was impressed with the considerable number of subjects willing to leave a mark in the workshops and in the hallways of the institution. The main objective of this research project is, therefore, to (i) analyse how inscription production can make conversation networks explicit and (ii) modulate the act of talking, setting new distinctions and emotions. This study is a qualitative intervention research which originated from the accomplishment of paths using TICs (information and communication technologies) by scope areas of PSF. Presenting the path as an indispensable method in consolidating work, this project has enabled a performative operation when meeting the inscriptions of that talking, which, during moments of collective problematisation, were reconfigured in the forms of photography and video. Aimed at a conversation between the participants and other networks, the Path Workshop resulted in shared actions which, at moments of breakdowns, opened new pathways into inventive cognition.

Chalcogenide glasses are highly nonlinear optical materials which can be used for fabricating active and passive photonic devices. This thesis work deals with the fabrication of buried, three dimensional, channel waveguides in chalcogenide glasses, using ultrafast laser inscription technique. The femtosecond laser pulses are focused into rare earth ions doped and undoped chalcogenide glasses, few hundred microns below from the surface to modify the physical properties such as refractive index, density, etc. These changes are made use in the fabrication of active and passive photonic waveguides which have applications in integrated optics. The first chapter provides an introduction to the fundamental aspects of femtosecond laser inscription, laser interaction with matter and chalcogenide glasses for photonic applications. The advantages and applications of chalcogenide glasses are also described. Motivation and overview of the present thesis work have been discussed at the end. The methods of chalcogenide glass preparation, waveguide fabrication and characterization of the glasses investigated are described in the second chapter. Also, the details of the experiments undertaken, namely, loss (passive insertion loss) and gain measurements (active) and nanoindentation studies are outlined. Chapter three presents a study on the effect of net fluence on waveguide formation. A heat diffusion model has been used to solve the waveguide cross-section. The waveguide formation in GeGaS chalcogenide glasses using the ultrafast laser, has been analyzed in the light of a finite element thermal diffusion model. The relation between the net fluence and waveguide cross section diameter has been verified using the experimentally measured properties and theoretically predicted values. Chapter four presents a study on waveguide fabrication on Er doped Chalcogenide glass. The active and passive characterization is done and the optimal waveguide fabrication parameters are given, along with gain properties for Er doped GeGaS glass. A C-band waveguide amplifier has been demonstrated on Chalcogenide glasses using ultrafast laser inscription technique. A study on the mechanical properties of the waveguide, undertaken using the nanoindentation technique, is presented in the fifth chapter. This work brings out the close relation between the change in mechanical properties such as elastic modulus and hardness of the material under the irradiation of ultrafast laser after the waveguide formation. Also, a threshold value of the modulus and hardness for characterizing the modes of the waveguide is suggested. Finally, the chapter six provides a summary of work undertaken and also discusses the future work to be carried out.

"Mémoire présenté à la Faculté des études supérieures en vue de l'obtention du grade de Maître en droit (LL.M.)" / Le présent texte a pour sujet la Base de données nationale d'inscription, système d'inscription obligatoire depuis quelques mois pour l'ensemble des firmes de courtage et des représentants en valeurs mobilières au Canada, à l'exception de ceux et celles qui n'exercent leurs activités qu'en territoire québécois. La question de la protection des renseignements personnels compris dans cette base de données y est analysée en portant une attention particulière à la pluralité des régimes de protection qui évolue au Canada. En effet, différentes règles s'appliquent selon que l'on est en présence d'un organisme public ou une entreprise du secteur privé et selon que la « transaction» est intraprovinciale ou extraprovinciale. La Base de données nationale d'inscription remplace dorénavant la procédure d'inscription sur support papier. Les documents issus de ce système informatique possèdent des caractéristiques propres et certaines règles doivent être respectées afin de leurs conférer la même valeur juridique que les documents papier. Finalement, la compilation de l'information dans cette gigantesque base de données serait futile s'il n'était pas possible d'accéder aux renseignements qui y sont contenus. Une fois les différents types d'accès définis, une comparaison sera faite avec certains systèmes d'inscription en ligne américains. La technologie bouleverse nos habitudes dans tous les secteurs de l'économie. Les finances ne sont pas en reste. Avec la Base de données nationale d'inscription, c'est tout le système d'inscription de l'industrie canadienne des valeurs mobilières qui prend un sérieux coup de jeune. Et il était temps ... / The subject of the present text concems the National Registration Database, a recent mandatory registration system designated for all brokerage firms and investment advisors across Canada, with the exception of those who exercise their activities exclusively in Quebec. The matter of protection of personal information included in this database is analyzed with an emphasis on the existence of multiple laws evolving in Canada. In fact, different mIes apply whether you are in the presence of a public body or an enterprise of the private sector and whether the "transaction" is concluded within or out of the province. The National Registration Database replaces the previous paper format registration procedure. The documents produced by this computerized system have their own particularities and certain mIes must be respected in order to maintain a legal value equal to the priOf format. Finally, the compiling of information found in this enormous database would be useless if it was not possible to access its information. Once the different types of access are determined, a comparison will be done with existing American online registration systems. It is obvious that technology has had a tremendous impact on the economy. Of course, the financial industry is affected. With the National Registration Database, the whole Canadian securities registration system has had a total makeover. It was about time...

À la lumière de la théorie de l’identité narrative élaborée par Paul Ricœur, ce mémoire évoque la configuration identitaire des personnages dans les œuvres Cosmos et Les envoûtés de W. Gombrowicz, ainsi que To the Lighthouse et The Waves de V. Woolf. D’une part, nous analyserons l’obsession d’une mise en série aliénante dans le cas de Witold (Cosmos), suivi par un cas de dédoublement et de perte dans l’Autre chez Walczak (Les envoûtés). D’autre part, nous évoquerons le rapport à la famille (James Ramsay) en plus de l’inscription et de l’ancrage par le biais d’éléments prépondérants (The Waves). Il en résulte chez ces personnages, la conception d’une identité par l’entremise d’histoires et d’événements qui la façonnent en un parcours narratif singulier. / By the means of Paul Ricœur’s theory on narrative identity, the following thesis will examine the singular conceptions of identity in the works Cosmos and Les envoutés (W. Gombrowicz) as well as To the Lighthouse and The Waves by V. Woolf. On one hand, we will analyze the obsessive serialization behavior that Witold manifests in Cosmos followed by a case of complete loss of one’s self towards otherness. Furthermore, we will scrutinize the family turmoil between James Ramsay (To the Lighthouse) and his family members. Additionally, we will also inspect the adherence and anchoring of three protagonists towards the development of a unique perception of their environment (The Waves). Ultimately, the protagonists recognize that one’s self is intrically linked to individual stories and events that craft their own sense of being.

Parallèlement à la dernière réforme française du droit des sûretés, les sûretés réelles chinoises ont été rénovées par la loi sur les droits réels promulguée à la même période. En s’appuyant sur une étude compréhensive des normes législative et réglementaire autour du sujet, cette thèse, essentiellement basée sur le droit chinois, révèle qu’en matière de sûreté réelle, le droit chinois se nuance du droit français et analyse les raisons et les effets de ces différences au-dessous des termes ou notions similaires. Après l’étude comparative, la thèse arrive à la conclusion que le droit chinois des sûretés réelles nécessite un futur regroupement en dépit de la nouvelle loi sur les droits réels. / During the same period, a reform of security law had completed in France, while the Chinese real rights law which has renovated security rights in rem was about to be promulgated in China. This thesis, based on Chinese law and drawing upon a comprehensive study of laws and administrative regulations on the subject, reveals the differences between Chinese and French law and analyze their cause and effect behind similar terms and notions. Grounded on the comparative study, the thesis draws the conclusion that the Chinese system of security rights in rem requires a further reform despite the arrival of new law.

L'inscription laser directe est un domaine de recherche en croissance depuis ces deux dernières décennies, fournissant un moyen efficace et robuste pour inscrire directement des structures en trois dimensions (3D) dans des matériaux transparents tels que des verres en utilisant des impulsions laser femtosecondes. Cette technique présente de nombreux avantages par rapport à la technique de lithographie, qui se limite à la structuration en deux dimensions (2D) et implique de nombreuses étapes de fabrication. Cela rend la technique d’inscription laser direct bien adaptée aux nouveaux procédés de fabrication. Généralement, l’inscription laser dans les verres induit des changements physiques tels qu'un changement permanent de l'indice de réfraction localisé. Ces modifications ont été classés en trois types distincts : (Type I, Type II et Type III). Dans ce travail, nous présentons un nouveau type de changement d'indice de réfraction, appelé type A qui est basé sur la création d’agrégats d'argent photo-induit. En effet, dans des verres dans lesquels sont incorporés des ions argent Ag+, lors de leurs synthèses, l’inscription laser directe induit la création d’agrégats d’argent fluorescents Agmx+ au voisinage du voxel d’interaction. Ces agrégats modifient localement les propriétés optiques comme : la fluorescence, la non-linéarité et la réponse plasmonique du verre. Ainsi, différents guides d'ondes, un séparateur de faisceau 50-50, ainsi que des coupleurs optiques ont été inscrits en se basant sur ce nouveau Type A et complétement caractérisés. D'autre part, une étude comparative entre les deux types de guides d'ondes (type A et type I) est présentée, tout en montrant qu’en ajustant les paramètres laser, il est possible de déclencher soit le Type I soit le Type A. Enfin, en se basant sur des guides d’ondes de type A inscrits proche de la surface du verre, un capteur d'indice de réfraction hautement sensible a été inscrit dans une lame de verre de 1 cm de long. Ce capteur miniaturisé peut présenter deux fenêtres de détection d’indice, ce qui constitue une première mondiale. Les propriétés des guides d'ondes inscrits dans ces verres massifs ont été transposées à des fibres en forme de ruban, du même matériau contenant de l'argent. Les résultats obtenus dans ce travail de thèse ouvrent la voie à la fabrication de circuits intégrés en 3D et de capteurs à fibre basés sur des propriétés optiques originales inaccessibles avec des guides d’onde de Type I standard. / Direct Laser Writing (DLW) has been an exponentially growing research field during the last two decades, by providing an efficient and robust way to directly address three dimensional (3D) structures in transparent materials such as glasses using femtosecond laser pulses. It exhibits many advantages over lithography technique which is mostly limited to two dimensional (2D) structuring and involves many fabrication steps. This competitive aspect makes the DLW technique suitable for future technological transfer to advanced industrial manufacturing. Generally, DLW in glasses induces physical changes such as permanent local refractive index modifications that have been classified under three distinct types: (Type I, Type II & Type III). In silver containing glasses with embedded silver ions Ag+, DLW induces the creation of fluorescent silver clusters Agmx+ at the vicinity of the interaction voxel. In this work, we present a new type of refractive index change, called type A that is based on the creation of the photo-induced silver clusters allowing the creation of new linear and nonlinear optical waveguides in silver containing glasses. Various waveguides, a 50-50 Y beam splitter, as well as optical couplers, were written based on type A modification inside bulk glasses and further characterized. On the other hand, a comparison study between type A and type I waveguides is presented, showing that finely tuning the laser parameters allows the creation of either type A or type I modification inside silver containing glasses. Finally, based on type A near-surface waveguides, a highly sensitive refractive index sensor is created in a 1 cm glass chip, which could exhibit a pioneer demonstration of double sensing refractive ranges. The waveguiding properties observed and reported in the bulk of such silver containing glasses were transposed to ribbon shaped fibers of the same material. Those results pave the way towards the fabrication of 3D integrated circuits and fiber sensors with original fluorescent, nonlinear and plasmonic properties that are not accessible using the standard type I modification

Ph.D. Faculty of Humanities, University of the Witwatersrand, 2011 / This study analyses the manner in which animals are represented in selected poetry from Malawi, Zimbabwe and South Africa. It discusses the various modes of animal representation the poets draw on, and the ideological influences on their manner of animal representation. It explores the kinds of poetic forms the poets employ in their representation of animals and examines the manner in which ecological or environmental issues are reflected in the poetry. Further, the study determines the extent to which the values expressed in the poems are consistent with, or different from, current ecological orthodoxies and the ways in which the metaphors generated in relation to animals influence the way we treat them. The study shows that in the selected poetry animals occupy a significant position in the poets’ exploration of social, psychological, political, and cultural issues. As symbols in, and subjects of, the poetry animals, in particular, and nature in general, function as tools for the poets’ conceptualisation and construction of a wide range of cultural, political, and philosophical ideas, including among others, issues of justice, identity, compassion, relational selfhood, heritage, and belonging to the cosmos. Hence, the animal figure in the poetry acts as a site for the convergence of a variety of concepts the poets mobilise to grapple with and understand relevant political, social, psychological and ecological ideas. The study advances the argument that studying animal representation in the selected poetry reveals a range of ecological sensibilities, as well as the limits of these, and opens a window through which to view and appreciate the poets’ conception, construction and handling of a variety of significant ideas about human to human relationships and human-animal/nature relationships. Further, the study argues that the poets’ social vision influences their animal representation and that their failures at times to fully see or address the connection between forms of abuse (nature and human) undercuts their liberationist quests in the poetry.

Psychologue(s) clinicien(s), confrontés aux solutions inventées par les sujets pour trouver à se loger dans le lien social à l’adolescence, force est de constater l’existence de pannes au moment de ce franchissement. La prééminence du discours résultant du mariage de la technoscience et du marché pourrait en être la cause. Ces ravages postmodernes s’expriment particulièrement dans le champ de l’enfance en danger. La prise en compte de la parole semble impossible dans ces institutions gagnées elles aussi par l’illusion de l’immédiat au détriment de la subjectivité. L’adolescent ne serait plus en danger mais réduit à ses troubles de conduites dangereuses ou déviantes. La protection de l’enfance pourrait-elle redevenir une adresse, le lieu d’une clinique opérante? Cette pratique, à l’opposé de toute orthopédie, viserait la rectification subjective, comme définie par Lacan. Les effets de cette clinique ne surviendraient qu’à la condition d’une écoute singulière orientée par la psychanalyse. Tel est ce que cette recherche s’efforce de démontrer à partir de la clinique d’adolescents accueillis « en protection de l’enfance ». / Clinical psychologist(s), we are dealing with the solutions invented by those in adolescence to find to find accommodation in the social link. Force is to note breakdowns at that crossing time. The preeminence of consequences from marriage of technoscience and market could be the cause. These postmodern ravages are particularly expressed in the field of child welfare system. Taking into account of speaking seems impossible in these institutions also won by the illusion of the immediacy at the expense of subjectivity. Teenager would no longer be in danger but reduced to his dangerous or deviant conduct disorders. Could the child welfare system become an address again, a place of an operating clinic? This practice, contrary to any orthopedic, would seek subjective rectification, as defined by Lacan. Effects of this clinic occur only under the condition of a singular listening driven by psychoanalysis. This is what this research tries to demonstrate from the clinic of teenagers welcomed in child welfare system.
