Linda Hogan é uma autora Chickasaw cuja extensa obra inclui romances, contos, poesia, drama e ensaios. Da mesma forma, ela é uma ambientalista cujo ativismo se baseia em uma compreensão Nativo-Americano da natureza e das relações entre os seres humanos e não-humanos. Focando em dois de seus romances, Solar Storms (1995) e Power (1998), a presente dissertação explora os processos de cura de suas protagonistas, Angela e Omishto, respectivamente. Em ambos romances, as personagens se engajam em um movimento de abandono do modo de ser Euro-americano – um modo de ser fortemente orientado pela ideologia do Destino Manifesto –, em direção a um reencontro com sua ancestralidade nativa e a uma apreensão tribal da vida e do mundo. Especificamente, esse trabalho explora o gradual engajamento das personagens no que a autora Laguna Paula Gunn Allen (1992) define como um senso de tempo cerimonial – a ceremonial time sense: uma experiência temporal particular que engendra uma integração psíquica, e se opõe à experiência cronológica e mecânica do tempo, a qual produz fragmentação no sentido de fortalecer a sensação de separação entre tempo e espaço, pessoa e lugar, natureza e cultura. Esse trabalho analisa como o movimento das personagens em direção a um rico autorreconhecimento enquanto indígenas (OWENS, 1994) representa um movimento de abertura aos fluxos do mundo, bem como um processo de dissolução de categorias fortemente enraizadas, tais quais sujeito e objeto, eu interno e mundo externo. Além disso, a presente dissertação examina de que forma um senso de tempo cerimonial se conecta à noção de sacred hoop (Plains tribes) – uma unidade abrangente que abarca a existência como um todo, e na qual todos os movimentos estão conectados e se relacionam entre si. / Linda Hogan is a Chickasaw author whose extensive work includes novels, short stories, plays, poetry, and essays. She is also an environmentalist whose activism is built upon a Native understanding of nature and the relations between human and nonhuman beings. This thesis focuses on two of her novels, Solar Storms (1995) and Power (1998), and explores the healing processes of their protagonists, Angela and Omishto, respectively. In both novels, the characters engage in a movement of abandoning a mainstream American way of being – a way of being highly informed by the ideology of Manifest Destiny – toward a reconnection with their Native ancestry and a tribal apprehension of life and the world. Specifically, this work explores the characters’ gradual engagement in what Laguna author Paula Gunn Allen (1992) defines as a ceremonial time sense, a particular experience of time that engenders a psychic integration, as opposed to a mechanical, clock-based time sense, which generates fragmentation and enhances a separation between time and space, person and place, nature and culture. This work explores how the characters’ movement toward a rich self-recognition as Indians (OWENS, 1994) represents a movement of opening to the motions of the lifeworld, as well as the dissolution of deep-rooted categories such as subject and object, internal self and external world. Furthermore, this thesis examines how a ceremonial time sense is connected to the Plains tribes’ conception of a sacred hoop – an all-encompassing unity that contains the whole of existence, and in which all movement is related to all other movement.

O presente trabalho estuda as figurações da homossexualidade e da homoafetividade no livro King & King, de Linda de Haan e Stern Nijland, e no filme Orações para Bobby, de Russel Mulcahy. Dialogamos com as duas e apontamos para as suas diferenças e complementaridades. Nossa análise está centrada nas relações de poder e afetividade presentes em seus processos discursivos. Nossa pesquisa fundamenta-se, primordialmente, em dois fecundos teóricos da modernidade, Michel Foucault e Judith Butler, e visa a compreender o exercício disciplinador na construção e manutenção das ordens regulatórias da homossexualidade e da homoafetividade. / The present work studies the figurations of homosexuality and homoaffection in the book King & King, by Linda de Haan and Stern Nijland, and in the film Prayers for Bobby, by Russel Mulcahy. We dialogue with both and point to their differences and complementarities. Our analysis is centered on the relations of power and affectivity presented in their discursive processes. Our research is based primarily on two fecund scholars of modernity, Michel Foucault and Judith Butler, and aims to understand the disciplinary exercise in the construction and maintenance of the regulatory orders of homosexuality and homoaffection.

Com a disponibilidade de redes que ligam estações cada vez mais poderosas a baixos custos, o interesse em torno de ferramentas que suportam a programação paralela em arquiteturas deste tipo tem aumentado significativamente. Esta dissertação trata do projeto e implementação de YALI (Yet Another Linda Implementation), uma ferramenta destinada ao desenvolvimento e execução de programas paralelos em redes heterogêneas de computadores. Com o objetivo de oferecer uma interface simples e flexível para os usuários programadores, YALI baseia-se no modelo Linda[GEL85], que destaca-se por utilizar uma abstração de alto nível para a cooperação entre processos. Em Linda, processos interagem por intermédio de uma memória associativa logicamente compartilhada, denominada Espaço de Tuplas. Entre outras vantagens deste modelo pode-se citar a simplicidade de suas primitivas e a possibilidade de incorporá-las a uma linguagem seqüencial conhecida, o que contribui fortemente para sua fácil assimilação, mesmo por usuários com pouca experiência em programação paralela. Após uma descrição detalhada do modelo Linda, este trabalho discute varias questões envolvidas no projeto e implementação de sistemas nele baseados. Para oferecer uma visão pratica das soluções mais freqüentemente adotadas para estas questões, quatro sistemas que implementam o modelo para programação paralela em redes são apresentados e avaliados. São eles: Glenda, uma implementacao do modelo baseada na ferramenta PVM (Parallel Virtual Machine); POSYBL (PrOgramming SYstem for distriButed appLications), um sistema construído através de recursos de sistemas operacionais compatíveis com Unix; p4-Linda, construído a partir da ferramenta de programação paralela p4 e, por fim, Network-Linda, uma implementação comercial do modelo. Depois do estudo dos quatro sistemas acima, o projeto de YALI e discutido detalhadamente. Decidiu-se, inicialmente, que YALI deveria incorporar o modelo Linda a linguagem C, que é largamente utilizada no desenvolvimento de programas de propósito geral. Além disso, optou-se por estender o modelo com algumas novas primitivas, de modo a oferecer maior poder de expressão ao usuário. Basicamente, as primitivas que YALI acrescenta ao modelo servem para dar suporte a operações globais e a criação dinâmica de threads. Operações globais servem para expressar a comunicação e a sincronização entre múltiplos processos, sendo utilizadas com bastante freqüência em vários tipos de programas paralelos. YALI suporta operações globais de maneira totalmente ortogonal ao modelo Linda, garantindo melhor desempenho sem afetar o nível de abstração oferecido. o suporte a criação dinâmica de threads, por outro lado, tem o objetivo de permitir a exploração de um paralelismo de granularidade fina, adequado ate mesmo a execução de rotinas simples em paralelo. Para suportar o desenvolvimento e execução de aplicações paralelas, YALI e implementado através de três componentes distintos. O primeiro e um pré-processador, que garante uma interface simplificada com o usuário. 0 segundo e uma biblioteca, que contem as rotinas de suporte as primitivas YALI e deve ser ligada aos programas de usuários. O terceiro componente, por fim, e um utilitário destinado a controlar a inicialização e o termino de aplicações paralelas, que baseia-se em uma configuração estabelecida pelo usuário para distribuir processos sobre uma rede de computadores. Ao contrário da maioria dos sistemas baseados em Linda, YALI implementa um espaço de tuplas distribuído entre os processos que compõem uma aplicação paralela, dispensando o use de processos especializados no gerenciamento de tuplas. Para isso, YALI utiliza múltiplas threads em cada processo definido pelo usuário, e distribui tuplas sobre estes processos através de um mecanismo baseado em hashing. A implementação de YALI leva em conta a heterogeneidade inerente a ambientes de rede, permitindo que maquinas com diferentes arquiteturas e sistemas operacionais sejam utilizadas na execução de programas paralelos. Por fim, YALI é totalmente implementado a partir de recursos presentes em sistemas compatíveis com Unix, de modo a aumentar sua portabilidade e garantir sua eficiência. / With the availability of networks connecting powerful workstations at a low cost, increasing interest has been devoted to systems that support parallel programming in such architectures. This document describes the design and implementation of YALI (Yet Another Linda Implementation), a tool that allows the development and execution of parallel programs in heterogeneous computer networks. Aiming to provide a simple and flexible interface for its users, YALI is based on the Linda parallel programming model[GEL85], that outstands in providing a high level abstraction for cooperation between processes. In Linda, communication and synchronization take place through an associative, logically shared memory called Tuple Space. Among the advantages of this model, one can mention the simplicity of its primitives, and the possibility of incorporate them in a well-known sequential language. These characteristics make Linda easy to learn, even to users with little experience in parallel programming. After a detailed description of the Linda model, this document discusses some design and implementation issues related to Linda-based systems. In order to provide a practical view of some usual solutions to address these issues, four Linda-based systems are presented and evaluated. These systems are: Glenda, an implementation of Linda built on top of PVM (Parallel Virtual Machine); POSYBL (PrOgramming SYstem for distriButed appLications), that relies on features provided by Unix-like operating systems to implement the model; p4-Linda, built on top of p4 parallel programming tool and, at last, Network-Linda, a comercial product based on Linda. All these systems, as YALI, are specially tailored to parallel programming in computer networks. Following the study of the four systems, this documents presents the design of the YALI system. One of the first design decisions was to incorporate the Linda primitives to the C language, that is broadly used as a general purpose programming language. In addition, a set of new primitives was designed as an extension to the original model, in order to increase YALI's expressivenes. Basically, the new primitives support global operations and dynamic thread creation. Global operations are useful to express communication and synchronization among multiple processes, and are frequently used many classes of parallel programs. YALI gives support to global operations in a way that is totally ortoghonal to the Linda model, ensuring better performance without affecting the abstraction level inherent to Linda-based systems. The support to dynamic thread creation, on the other hand, is helpful to explore lightweight parallelism, which allows the execution of simple routines in parallel. To support the development and execution of parallel applications, YALI is made up of three distinct components. The first is a pre-processor, that provides a simple user interface. The second is a library, that must be linked to the user programs since it's where YALI primitives are actuall y implemented. Finally, the third component is an utility that controls initialization and termination of parallel applications, which takes configuration parameters from the user to distribute processes over a newtork. In contrast with most Linda-based systems, YALI relies on a tuple space that is distributed among the processes in the same parallel application, so that intermediate tuple managers are not necessary To implement that, multiple threads are embedded in each user process, and tuples are spread over the processes in the basis of a hashing mechanism. YALI's implementation takes in account the inherent heterogeneity of network environments, allowing machines with different architectures and operating systems to be used in the execution of parallel programs. Finally, YALI is build on top of common features of Unix-like operating systems, in order to increase its efficiency and portability.

There is something magical about shoes… They can create an irresistible desire or be the one thing that we want to get rid of the most at the end of a long day. When people by shoes the chose more out of appearance rather then comfort. The result is a fact. The feet feel tired and soar after a couple of hours and the only thoughts are about the aching feet that firmly object to the way there being treated. Who will say no to a relaxing foot massage in this moment? …Sometimes they seem to have shrunken after a couple of hours… Does your legs feel heavy and swollen when you are sitting down for a couple of hours, maybe in front of the computer or during a flight? Do you have or are you starting to get visible veins alongside your legs? Do your feet often turn cold? Then maybe you are one of the 40 % in Sweden who suffers from reduced circulation of the blood, a so called vein insufficiency. This projects aims to find a solution that will ease the pain for a foot that feels tired and soar, beside this a solution that also increases the blood circulation in the legs during a longer time sitting down. The work has been carried out according to the principles of DPD - Dynamic Product Development (Ottosson, 2002). The project started with an idea and resulted in a product that is ready for the market. The project has resolved in two different solutions hence the problem was separated into two that would hopefully be introduced on the market shortly: Solution one is a massage slipper Njuta (English = Enjoy) that easy and quickly eases the pain in the feet with an adjustable foot massage. The tramp machine Cirkulera (English= Circulate) is used to keep the blood circulation going and prevent possible complaint. The solution activates the muscle pump so it can help to press the blood back up to the heart through the veins and this will prevent the blood from in slogging in the feet and legs.
