A transinstitucionalização no caso do fechamento da Casa de Saúde Dr. Eiras- Paracambi: uma questão paradoxal

O presente estudo teve por objetivo analisar o processo de fechamento da Casa de Saúde Dr. Eiras- Paracambi, uma clínica psiquiátrica privada que esteve em processo de fechamento por 12 anos e que efetivamente foi fechada em março de 2012. Este processo envolveu a gestão estadual de saúde mental, o município de Paracambi, os municípios que tinham pacientes internados, o Ministério Público Federal e Estadual e a Área Técnica de Saúde Mental do Ministério da Saúde. A pesquisa pretendeu analisar as respostas políticas que o município do Rio de Janeiro, que apresentava o maior número de internações, articulou para seus munícipes que se encontravam internados nesta instituição, focando na transinstitucionalização, ou seja, na transferência dos pacientes da Casa de Saúde Dr. Eiras-Paracambi para outras instituições de internações psiquiátricas ou clínicas. Procurou-se entender por que essa resposta foi pensada e como foi realizada por este município e compreender, a partir dos profissionais, como foi feita a passagem dos pacientes da Casa de Saúde Dr. Eiras-Paracambi para outra instituição e quais são as perspectivas para a continuidade do acompanhamento dos casos transinstitucionalizados. A pesquisa se dividiu em duas fases, em ambas foram realizadas entrevistas semi-estruturadas. A primeira fase partiu do recolhimento das falas de gestores, numa visada mais geral do processo, inclusive investigando a participação de outros municípios. A segunda fase, por sua vez, priorizou a experiência dos profissionais, que trabalham ou trabalharam mais diretamente com os pacientes transferidos no município do Rio de Janeiro. As instituições escolhidas para a segunda fase foram o Instituto Municipal Nise da Silveira e o Centro de Atenção Psicossocial Torquato Neto. Constatamos que além de diferentes sentidos para desinstitucionalização (desospitalização; desassistência;desconstrução; novas institucionalidades e intencionalidade do tratamento), podemos falar em vários tipos de transinstitucionalização: para hospital ou outro estabelecimento asilar; para estabelecimento privado ou público; para estabelecimento psiquiátrico ou clínico. O tema da transinstitucionalização foi abordado como um paradoxo, superando a dicotomia problema- solução.

Village fisheries management and community-owned marine protected areas in Samoa

As in many tropical countries, subsistence fishers in Samoa live in discrete communities which have a high level of marine knowledge and some degree of control of adjacent waters. These factors provide an ideal basis for motivating communities to manage their marine resources. In Samoa, a community-based fisheries extension program encouraged each village community to define its key problems, discuss causes, propose solutions and take appropriate actions. Various village groups provided information which was recorded as problem/solution trees. The extension process culminated in a Village-Fisheries Management Plan which listed the resource management and conservation undertakings of the community. Undertakings range from enforcing laws banning destructive fishing methods to protecting critical marine habitats. Within the first eighteen months, the extension process commenced in 57 villages of which 40 have produced Village Fisheries Management Plans. An unexpectedly large number (32) or these villages chose to establish Marine Protected Areas, the first community-owned marin reserves in the country.

Gays contanto suas histórias: uma análise organizacional, lexical e discursiva das narrativas de sair do armário

Este trabalho tem por objetivo investigar as histórias de sair do armário sob seu aspecto organizacional, lexical e discursivo. Busca-se apontar que padrões organizacionais prevalecem nas histórias, que léxicos significativos predominam e como os léxicos predominantes são avaliados em termos de Afeto, Julgamento e Apreciação. Para o exame organizacional, a análise se apropria do quadro analítico de Labov e colaboradores (1967; 1972), por ser pioneiro nos estudos sobre narrativas orais de experiência pessoal; em seguida, lança mão dos elementos do Padrão Problema-Solução (PPS), proposto por Hoey (1983; 2001), por iluminar o aspecto cíclico das referidas histórias. Para a análise lexical, esse estudo se ampara nos preceitos e técnicas da investigação eletrônica de textos da Linguística de Corpus (TOGNINI BONELILI, 2001; SINCLAIR, 2004; BERBER-SARDINHA, 2004; McENERY e HARDIE, 2011), conjugado ao conjunto de programas WordSmith Tool 5.0 (SCOTT, 2010). Já sobre o aspecto discursivo, em especial sobre a linguagem da avaliação, a análise privilegiou a metafunção interpessoal da Linguística Sistêmico Funcional (Halliday, 2004) e lançou mão das categorias do subsistema da ATITUDE da Teoria da Avaliatividade, proposto por Martin (2000) e Martin e White (2005). O Corpus analisado consiste de sete narrativas, coletadas pelo método da Entrevista Narrativa, à qual se voluntariaram homossexuais do sexo masculino, entre (20) vinte a (30) anos de idade, oriundos da zona norte do Rio de Janeiro. Os resultados da análise da organização da narrativa mostraram que as histórias de sair do armário são episódicas, são contadas com muitos recursos avaliativos como descritos por Labov e se organizam por meio do Padrão Problema-Solução. Os resultados da análise lexical revelaram a predominância do item eu e mãe/ela nas sete histórias coletivamente. Por fim a análise discursiva, sob a ótica da linguagem atitudinal, aponta que os itens eu e mãe/ela, que apontam para o narrador e suas mães, são marcados por Afeto (emoções) e Julgamento (comportamento). A dissertação em seu final combina as três linhas de análise para fazer uma reflexão sobre o peso social do que significa sair do armário para o sujeito gay

Aplicação da técnica simulated annealing na investigação da ciclagem de nitrogênio na inteface água-sedimento

Neste trabalho é apresentado a aplicação de um método de otimização a fim de estimar parâmetros que normalmente estão presentes na modelagem matemática da dinâmica de espécies químicas na interface água-sedimento. O Problema Direto aqui consistiu na simulação das concentrações das espécies orgânicas e inorgânicas (amônia e nitrato) de nitrogênio, num ambiente idealizado, o qual foi fracionado em quatro camadas: uma camada de água (1 metro) e três camadas de sedimento (0-1 cm, 1-2 cm e 2-10 cm). O Problema Direto foi resolvido pelo Método de Runge Kutta, tendo sido gerada uma simulação de 50 dias. Na estimativa dos coeficientes de difusão e porosidade foi aplicado o Método Simulated Annealing (SA). A eficiência da estratégia aqui adotada foi avaliada através do confronto entre dados experimentais sintéticos e as concentrações calçadas pela solução do Problema Direto, adotando-se os parâmetros estimados pela SA. O melhor ajuste entre dados experimentais e valores calculados se deu quando o parâmetro estimado foi a porosidade. Com relação à minimização da função objetivo, a estimativa desse parâmetro também foi a que exigiu menor esforço computacional. Após a introdução de um ruído randômico às concentrações das espécies nitrogenadas, a técnica SA não foi capaz de obter uma estimativa satisfatória para o coeficiente de difusão, com exceção da camada 0-1 cm sedimentar. Para outras camadas, erros da ordem de 10 % foram encontrados (para amônia na coluna dágua, pro exemplo). Os resultados mostraram que a metodologia aqui adotada pode ser bastante promissora enquanto ferramenta de gestão de corpos dágua, especialmente daqueles submetidos a um regime de baixa energia, como lagos e lagoas costeiras.

Análise dos problemas direto e inverso em um modelo de evolução populacional através de transformações integrais e inferência bayesiana

Modelos de evolução populacional são há muito tempo assunto de grande relevância, principalmente quando a população de estudo é composta por vetores de doenças. Tal importância se deve ao fato de existirem milhares de doenças que são propagadas por espécies específicas e conhecer como tais populações se comportam é vital quando pretende-se criar políticas públicas para controlar a sua proliferação. Este trabalho descreve um problema de evolução populacional difusivo com armadilhas locais e tempo de reprodução atrasado, o problema direto descreve a densidade de uma população uma vez conhecidos os parâmetros do modelo onde sua solução é obtida por meio da técnica de transformada integral generalizada, uma técnica numérico-analítica. Porém a solução do problema direto, por si só, não permite a simulação computacional de uma população em uma aplicação prática, uma vez que os parâmetros do modelo variam de população para população e precisam, portanto, ter seus valores conhecidos. Com o objetivo de possibilitar esta caracterização, o presente trabalho propõe a formulação e solução do problema inverso, estimando os parâmetros do modelo a partir de dados da população utilizando para tal tarefa dois métodos Bayesianos.

Computation and Pre-Parametric Design

My work is broadly concerned with the question "How can designs bessynthesized computationally?" The project deals primarily with mechanical devices and focuses on pre-parametric design: design at the level of detail of a blackboard sketch rather than at the level of detail of an engineering drawing. I explore the project ideas in the domain of single-input single-output dynamic systems, like pressure gauges, accelerometers, and pneumatic cylinders. The problem solution consists of two steps: 1) generate a schematic description of the device in terms of idealized functional elements, and then 2) from the schematic description generate a physical description.

Symbolic Mathematical Laboratory

A large computer program has been developed to aid applied mathematicians in the solution of problems in non-numerical analysis which involve tedious manipulations of mathematical expressions. The mathematician uses typed commands and a light pen to direct the computer in the application of mathematical transformations; the intermediate results are displayed in standard text-book format so that the system user can decide the next step in the problem solution. Three problems selected from the literature have been solved to illustrate the use of the system. A detailed analysis of the problems of input, transformation, and display of mathematical expressions is also presented.

Predicting conversion to dementia in a memory clinic: A standard clinical approach compared with an empirically defined clustering method (latent profile analysis) for mild cognitive impairment subtyping

Introduction
Mild cognitive impairment (MCI) has clinical value in its ability to predict later dementia. A better understanding of cognitive profiles can further help delineate who is most at risk of conversion to dementia. We aimed to (1) examine to what extent the usual MCI subtyping using core criteria corresponds to empirically defined clusters of patients (latent profile analysis [LPA] of continuous neuropsychological data) and (2) compare the two methods of subtyping memory clinic participants in their prediction of conversion to dementia.

Methods
Memory clinic participants (MCI, n = 139) and age-matched controls (n = 98) were recruited. Participants had a full cognitive assessment, and results were grouped (1) according to traditional MCI subtypes and (2) using LPA. MCI participants were followed over approximately 2 years after their initial assessment to monitor for conversion to dementia.

Results
Groups were well matched for age and education. Controls performed significantly better than MCI participants on all cognitive measures. With the traditional analysis, most MCI participants were in the amnestic multidomain subgroup (46.8%) and this group was most at risk of conversion to dementia (63%). From the LPA, a three-profile solution fit the data best. Profile 3 was the largest group (40.3%), the most cognitively impaired, and most at risk of conversion to dementia (68% of the group).

Discussion
LPA provides a useful adjunct in delineating MCI participants most at risk of conversion to dementia and adds confidence to standard categories of clinical inference.

Knowledge Management Techniques to Augment Textual CBR (PhD Thesis)

The past decade had witnessed an unprecedented growth in the amount of available digital content, and its volume is expected to continue to grow the next few years. Unstructured text data generated from web and enterprise sources form a large fraction of such content. Many of these contain large volumes of reusable data such as solutions to frequently occurring problems, and general know-how that may be reused in appropriate contexts. In this work, we address issues around leveraging unstructured text data from sources as diverse as the web and the enterprise within the Case-based Reasoning framework. Case-based Reasoning (CBR) provides a framework and methodology for systematic reuse of historical knowledge that is available in the form of problemsolution
pairs, in solving new problems. Here, we consider possibilities of enhancing Textual CBR systems under three main themes: procurement, maintenance and retrieval. We adapt and build upon the stateof-the-art techniques from data mining and natural language processing in addressing various challenges therein. Under procurement, we investigate the problem of extracting cases (i.e., problem-solution pairs) from data sources such as incident/experience
reports. We develop case-base maintenance methods specifically tuned to text targeted towards retaining solutions such that the utility of the filtered case base in solving new problems is maximized. Further, we address the problem of query suggestions for textual case-bases and show that exploiting the problem-solution partition can enhance retrieval effectiveness by prioritizing more useful query suggestions. Additionally, we illustrate interpretable clustering as a tool to drill-down to domain specific text collections (since CBR systems are usually very domain specific) and develop techniques for improved similarity assessment in social media sources such as microblogs. Through extensive empirical evaluations, we illustrate the improvements that we are able to
achieve over the state-of-the-art methods for the respective tasks.

Optimal methodology for distribution systems reconfiguration based on OPF and solved by decomposition technique

This paper presents a new and efficient methodology for distribution network reconfiguration integrated with optimal power flow (OPF) based on a Benders decomposition approach. The objective minimizes power losses, balancing load among feeders and subject to constraints: capacity limit of branches, minimum and maximum power limits of substations or distributed generators, minimum deviation of bus voltages and radial optimal operation of networks. The Generalized Benders decomposition algorithm is applied to solve the problem. The formulation can be embedded under two stages; the first one is the Master problem and is formulated as a mixed integer non-linear programming problem. This stage determines the radial topology of the distribution network. The second stage is the Slave problem and is formulated as a non-linear programming problem. This stage is used to determine the feasibility of the Master problem solution by means of an OPF and provides information to formulate the linear Benders cuts that connect both problems. The model is programmed in GAMS. The effectiveness of the proposal is demonstrated through two examples extracted from the literature.

Exploring the use of prediction and summarization to increase students' listening and reading comprehension /

This study examined the effect of expHcitly instructing students to use a repertoire of reading comprehension strategies. Specifically, this study examined whether providing students with a "predictive story-frame" which combined the use of prediction and summarization strategies improved their reading comprehension relative to providing students with generic instruction on prediction and summarization. Results were examined in terms of instructional condition and reading ability. Students from 2 grade 4 classes participated in this study. The reading component of the Canadian Achievement Tests, Second Edition (CAT/2) was used to identify students as either "average or above average" or "below average" readers. Students received either strategic predication and summarization instruction (story-frame) or generic prediction and summarization instruction (notepad). Students were provided with new but comparable stories for each session. For both groups, the researcher modelled the strategic tools and provided guided practice, independent practice, and independent reading sessions. Comprehension was measured with an immediate and 1-week delayed comprehension test for each of the 4 stories, hi addition, students participated in a 1- week delayed interview, where they were asked to retell the story and to answer questions about the central elements (character, setting, problem, solution, beginning, middle, and ending events) of each story. There were significant differences, with medium to large effect sizes, in comprehension and recall scores as a fimction of both instructional condition and reading ability. Students in the story-frame condition outperformed students in the notepad condition, and average to above average readers performed better than below average readers. Students in the story-frame condition outperformed students in the notepad condition on the comprehension tests and on the oral retellings when teacher modelling and guidance were present. In the cued recall sessions, students in the story-frame instructional condition recalled more correct information and generated fewer errors than students in the notepad condition. Average to above average readers performed better than below average readers across comprehension and retelling measures. The majority of students in both instructional conditions reported that they would use their strategic tool again.

Discours et politique du répertoire public de délinquants sexuels : la « Loi de Megan » au New Jersey

Le 29 juillet 1994, Megan Kanka, une jeune fille de sept ans de la municipalité de Hamilton au New Jersey, est enlevée, agressée sexuellement et tuée par ce qui se révélera être son voisin d’en face, Jesse Timmendequas. À l’époque, l’assaillant de Megan avait déjà fait l’objet de deux condamnations pour agression sexuelle. Suite à cette tragédie, les parents de Megan luttèrent pour la création d’une loi qui révélerait automatiquement au public l’identité et le lieu de résidence des délinquants sexuels. Moins de trois mois plus tard, la « Loi de Megan » était ratifiée. Ainsi un répertoire étatique centralisé de délinquants sexuels en partie disponible au public fut créé. Notre étude se centre sur ce cas et tente de comprendre comment une construction particulière de la délinquance sexuelle comme problème social mena à la réponse pénale spécifique qu’était la Loi de Megan. Pour ce faire, nous analysons les discours et argumentaires politiques en lien avec l’affaire. Huit entretiens avec différents acteurs impliqués dans le débat politique menant à la création de la loi de Megan furent effectués. Une analyse de plus de 150 articles de journaux et de quelques projets et textes de lois fut également effectuée. Nos résultats soulignent d’abord le rôle primordial qu’avait le contexte sociopolitique autant sur la construction du problème social de la délinquance sexuelle que sur la solution qui lui était liée. L’analyse du cas nous indique également que la dyade problème-solution s’élabora en conjonction, dans un cadre temporel uniforme, dont les seules étapes détectables sont celles du narratif de la mort de Megan et de l’élaboration concrète de la loi. En d’autres mots, la mort de Megan ne constituait qu’un point focal qui permit à des acteurs de mettre en pratique des concepts déjà largement partagés. L’étude conclue en liant le contexte sociopolitique du Canada à celui retrouvé dans notre étude de cas et suggère qu’une construction similaire de la délinquance sexuelle comme problème peut facilement être envisageable chez nous. Si personne ne souhaite l’occurrence d’une situation comparable à celle vécue par Megan Kanka et sa famille, cet élément nous apparaît comme étant celui qui propulserait réellement cette construction sur la place publique, à condition bien évidemment qu’une personne ou un groupe de personnes en fassent une question à débattre.

Développement d'une nouvelle méthode de caractérisation tissulaire basée sur l'élastographie ultrasonore : application pour le dépistage précoce du cancer du sein

Le cancer du sein est le cancer le plus fréquent chez la femme. Il demeure la cause de mortalité la plus importante chez les femmes âgées entre 35 et 55 ans. Au Canada, plus de 20 000 nouveaux cas sont diagnostiqués chaque année. Les études scientifiques démontrent que l'espérance de vie est étroitement liée à la précocité du diagnostic. Les moyens de diagnostic actuels comme la mammographie, l'échographie et la biopsie comportent certaines limitations. Par exemple, la mammographie permet de diagnostiquer la présence d’une masse suspecte dans le sein, mais ne peut en déterminer la nature (bénigne ou maligne). Les techniques d’imagerie complémentaires comme l'échographie ou l'imagerie par résonance magnétique (IRM) sont alors utilisées en complément, mais elles sont limitées quant à la sensibilité et la spécificité de leur diagnostic, principalement chez les jeunes femmes (< 50 ans) ou celles ayant un parenchyme dense. Par conséquent, nombreuses sont celles qui doivent subir une biopsie alors que leur lésions sont bénignes. Quelques voies de recherche sont privilégiées depuis peu pour réduire l`incertitude du diagnostic par imagerie ultrasonore. Dans ce contexte, l’élastographie dynamique est prometteuse. Cette technique est inspirée du geste médical de palpation et est basée sur la détermination de la rigidité des tissus, sachant que les lésions en général sont plus rigides que le tissu sain environnant. Le principe de cette technique est de générer des ondes de cisaillement et d'en étudier la propagation de ces ondes afin de remonter aux propriétés mécaniques du milieu via un problème inverse préétabli. Cette thèse vise le développement d'une nouvelle méthode d'élastographie dynamique pour le dépistage précoce des lésions mammaires. L'un des principaux problèmes des techniques d'élastographie dynamiques en utilisant la force de radiation est la forte atténuation des ondes de cisaillement. Après quelques longueurs d'onde de propagation, les amplitudes de déplacement diminuent considérablement et leur suivi devient difficile voir impossible. Ce problème affecte grandement la caractérisation des tissus biologiques. En outre, ces techniques ne donnent que l'information sur l'élasticité tandis que des études récentes montrent que certaines lésions bénignes ont les mêmes élasticités que des lésions malignes ce qui affecte la spécificité de ces techniques et motive la quantification de d'autres paramètres mécaniques (e.g.la viscosité). Le premier objectif de cette thèse consiste à optimiser la pression de radiation acoustique afin de rehausser l'amplitude des déplacements générés. Pour ce faire, un modèle analytique de prédiction de la fréquence de génération de la force de radiation a été développé. Une fois validé in vitro, ce modèle a servi pour la prédiction des fréquences optimales pour la génération de la force de radiation dans d'autres expérimentations in vitro et ex vivo sur des échantillons de tissu mammaire obtenus après mastectomie totale. Dans la continuité de ces travaux, un prototype de sonde ultrasonore conçu pour la génération d'un type spécifique d'ondes de cisaillement appelé ''onde de torsion'' a été développé. Le but est d'utiliser la force de radiation optimisée afin de générer des ondes de cisaillement adaptatives, et de monter leur utilité dans l'amélioration de l'amplitude des déplacements. Contrairement aux techniques élastographiques classiques, ce prototype permet la génération des ondes de cisaillement selon des parcours adaptatifs (e.g. circulaire, elliptique,…etc.) dépendamment de la forme de la lésion. L’optimisation des dépôts énergétiques induit une meilleure réponse mécanique du tissu et améliore le rapport signal sur bruit pour une meilleure quantification des paramètres viscoélastiques. Il est aussi question de consolider davantage les travaux de recherches antérieurs par un appui expérimental, et de prouver que ce type particulier d'onde de torsion peut mettre en résonance des structures. Ce phénomène de résonance des structures permet de rehausser davantage le contraste de déplacement entre les masses suspectes et le milieu environnant pour une meilleure détection. Enfin, dans le cadre de la quantification des paramètres viscoélastiques des tissus, la dernière étape consiste à développer un modèle inverse basé sur la propagation des ondes de cisaillement adaptatives pour l'estimation des paramètres viscoélastiques. L'estimation des paramètres viscoélastiques se fait via la résolution d'un problème inverse intégré dans un modèle numérique éléments finis. La robustesse de ce modèle a été étudiée afin de déterminer ces limites d'utilisation. Les résultats obtenus par ce modèle sont comparés à d'autres résultats (mêmes échantillons) obtenus par des méthodes de référence (e.g. Rheospectris) afin d'estimer la précision de la méthode développée. La quantification des paramètres mécaniques des lésions permet d'améliorer la sensibilité et la spécificité du diagnostic. La caractérisation tissulaire permet aussi une meilleure identification du type de lésion (malin ou bénin) ainsi que son évolution. Cette technique aide grandement les cliniciens dans le choix et la planification d'une prise en charge adaptée.

Learning associations between places and visual cues without learning to navigate: neither fornix nor entorhinal cortex is required

Rats with fornix transection, or with cytotoxic retrohippocampal lesions that removed entorhinal cortex plus ventral subiculum, performed a task that permits incidental learning about either allocentric (Allo) or egocentric (Ego) spatial cues without the need to navigate by them. Rats learned eight visual discriminations among computer-displayed scenes in a Y-maze, using the constant-negative paradigm. Every discrimination problem included two familiar scenes (constants) and many less familiar scenes (variables). On each trial, the rats chose between a constant and a variable scene, with the choice of the variable rewarded. In six problems, the two constant scenes had correlated spatial properties, either Alto (each constant appeared always in the same maze arm) or Ego (each constant always appeared in a fixed direction from the start arm) or both (Allo + Ego). In two No-Cue (NC) problems, the two constants appeared in randomly determined arms and directions. Intact rats learn problems with an added Allo or Ego cue faster than NC problems; this facilitation provides indirect evidence that they learn the associations between scenes and spatial cues, even though that is not required for problem solution. Fornix and retrohippocampal-lesioned groups learned NC problems at a similar rate to sham-operated controls and showed as much facilitation of learning by added spatial cues as did the controls; therefore, both lesion groups must have encoded the spatial cues and have incidentally learned their associations with particular constant scenes. Similar facilitation was seen in subgroups that had short or long prior experience with the apparatus and task. Therefore, neither major hippocampal input-output system is crucial for learning about allocentric or egocentric cues in this paradigm, which does not require rats to control their choices or navigation directly by spatial cues.

A multi level analysis on pollination-related policies

The paper explores pollination from a multi level policy perspective and analyses the institutional fit and inter play of multi-faceted pollination-related policies. First, it asks what the major policies are that frame pollination at the EU level. Second, it explores the relationship between the EU policies and localised ways of understanding pollination. Addressed third is how the concept of ecosystem services can aid in under- standing the various ways of framing and governing the situation. The results show that the policy systems affecting pollination are abundant and that these systems create different kinds of pressure on stakeholders, at several levels of society. The local-level concerns are more about the loss of pollination services than about loss of pollinators. This points to the problem of fit between local activity driven by economic reasoning and biodiversity-driven EU policies. Here we see the concept of ecosystem services having some potential, since its operationalisation can combine economic and environmental considerations. Further- more, the analysis shows how, instead of formal institutions, it seems that social norms, habits, and motivation are the key to understanding and developing effective and attractive governance measures.
