La présente étude vise l'exploration du phénomène de l'abandon dans le contexte du suivi psychosocial. Cette recherche qualitative vise à définir les motifs selon la perspective des intervenantes et la perspective des clientes afin de caractériser l'abandon et de mieux saisir les éléments impliqués d~ns le dynamisme motivationnel. De plus, cette étude explore certains aspects de l'alliance thérapeutique selon la perspective des clientes afin de circonscrire les variables individuelles et interactionnelles impliquées dans le processus transactionnel de l'abandon. Méthode: 5 intervenantes du CSSS-VC dans un CLSC de la région de Québec ont participé à la rencontre de groupe nominal et une entrevue semi-dirigée.a été effectuée auprès de 4 clientes ayant abandonné leur suivi psychosocial au même CLSC. Résultats: Les motifs déterminants selon la perspective des intervenantes concernent davantage des raisons personnelles aux clientes et à l'atteinte des obj ectifs. Les motifs déterminants selon la perspective des clientes sont davantage centrés autour de l'alliance thérapeutique et particulièrement en lien avec les caractéristiques de l'intervenante. Cependant, les difficultés associées aux définitions conceptuelles et aux catégorisations factorielles des motifs limitent les conclusions quant à une divergence des perspectives.

L'abandon du traitement chez les joueurs de jeux de hasard et d'argent n'est pas sans conséquence sur la pratique clinique ainsi que la recherche empirique. La présente recension vise à dresser un portrait de l'abandon et d'identifier des stratégies favorisant la rétention en traitement. La recension de la littérature est conduite sur les bases de données Medline, PsycInfo, Francis et Google Scholar. Également, les études canadiennes non publiées sont sollicitées. 53 études sont retenues. Les taux d'abandon pendant le traitement varient de 0 à 77,8%. Des 50 variables recensées associées à l'abandon, 14 influencent significativement l'abandon. Par ailleurs, seulement le statut matrimonial, l'âge du début des comportements de jeu, l'âge du début des comportements de jeu problématique, les traits obsessifs compulsifs, la recherche de sensations, la consommation d'alcool et de drogues ainsi que la modalité de traitement apparaissent comme des variables associées à l'abandon sans qu'aucune étude contredise cette association. Les définitions de l'abandon recensées peuvent être distinguées en trois catégories : nombre de séances complétées, changement clinique et autres (refus, exclusion et mutation à un autre programme). Les motifs d'abandon retrouvés dans les études réfèrent aux caractéristiques propres à l'usager, à l'intervenant et au traitement. La sollicitation d'un proche, la réduction de l'attente, les appels de soutien, le choix de la condition de traitement ainsi que la gratuité des frais de transport sont relevés comme des stratégies potentielles de réduction des taux d'abandon.

[pt] As descargas atmosféricas são de grande importância para o setor elétrico, sendo frequentemente responsáveis por desligamentos de linhas de transmissão, que podem desencadear uma sequência de eventos que levem o sistema elétrico interligado ao colapso. As longas extensões de linhas de transmissão, expostas a intemperes climáticas, determinam uma probabilidade significativa de incidência direta de descargas atmosféricas nestes equipamentos. Devido ao caráter estratégico das linhas para o fornecimento de energia e a constatação de que descargas atmosféricas estão entre as principais causas de desligamentos, torna-se importante o estudo do comportamento das descargas atmosféricas, antes do instante da ocorrência do desligamento das linhas de transmissão, para compreender os padrões característicos potenciais causadores destes desligamentos. Os estudos encontrados atualmente estão orientados na eficiência das redes de detecção de descargas atmosféricas e na identificação de condições climáticas que indiquem a ocorrência de raios de forma preditiva, sem correlação a ocorrências em linhas de transmissão. Assim, essa dissertação consiste na determinação do risco de desligamentos de linhas de transmissão por descargas atmosféricas, visando fornecer informações antecipadas e possibilitar ações operativas para manter a segurança do sistema elétrico. O modelo desenvolvido nesse estudo, denominado Risco de Desligamentos de Linhas de Transmissão por Raios (RDLR), é composto de dois módulos principais, sendo o primeiro o agrupamento do conjunto amostral de descargas atmosféricas, realizado através de um método baseado em densidade. Nesse módulo, os ruídos são eliminados de forma eficiente e são formados grupos representativos de descargas atmosféricas. O segundo módulo consiste em uma etapa classificatória, baseado em redes neurais artificiais para identificar padrões de grupos de descargas que representem riscos de desligamentos de linhas de transmissão. Visando a otimização do modelo, foi aplicado um método de seleção das variáveis, através de componentes principais, para determinar aquelas que mais contribuem na caracterização desses eventos. O modelo RDLR foi testado com dados reais dos registros de desligamentos de linhas de transmissão, associado a outro banco com dados reais contendo milhões de registros de descargas atmosféricas oriundos das redes de detecção de raios, sendo obtidos excelentes resultados na determinação dos riscos de desligamentos de linhas de transmissão por descargas atmosféricas. / [en] Atmospheric discharges are of great importance to power systems, and are often responsible for outages of transmission lines, which can trigger a sequence of events that leads to a system collapse. The long extensions of transmission lines, exposed to climatic conditions, create significant probability of direct incidence of atmospheric discharges in these equipments. Due to the strategic nature of power supply lines and the fact that atmospheric discharges are among the main causes of outages, it is important to study atmospheric discharges characteristics before failure of transmission lines and understand patterns that are responsible for interruptions. Current studies focus on efficiency of lightning detection networks and on identification of climatic conditions that indicate lightning occurrence in a predictive approach, without any correlation with transmission lines outages. Therefore, this thesis consists on real-time risk determination of transmission lines outage by lightning, providing early information to enabling operational procedures for power system safety. The proposed model, named Transmission Lines Outage Risk by Lightning (TLORL) is composed of two main modules: Atmospheric Discharge Data Clustering and Classification. In the atmospheric discharges data-clustering module, performed by a density-based method, the outages are efficiently eliminated and representative groups of atmospheric discharges are formed. The second module consists of a classification step, based on artificial neural networks, to identify patterns of discharges groups that represent risks to cause transmission lines outages. Aiming at improving the proposed model, principal components analysis (PCA) was applied to determine the input variables that most contribute to the events characterization. The TLORL model was tested with real data transmission line outages, associated to another database with millions lightning records from the detection networks, producing excellent results of transmission lines outages caused by atmospheric discharges.

Syftet med studien är att ge företag och organisationer kunskaper i hur de skapar relevant innehåll som intresserar deras kunder och hur de ska arbeta med sin marknadsföring på Facebook.  Metoder som används är en kvalitativ studie bestående av enskilda intervjuer med experter inom området för marknadsföring i sociala medier. Därtill har en kvantitativ studie genomförts för att mäta interaktionen på tre kommersiella Facebooksidor. Resultatet visar att det är viktigt att tänka efter vad som är målet och vilken utgång som marknadsföringen på Facebook kommer generera. Vidare är det inte ett ändamål i sig att få högt engagemang. Det krävs en kontinuerlig närvaro samt att företaget visar ett intresse och ger kunderna uppmärksamhet. Idag är användarna på Facebook mer anonyma än tidigare och det har blivit ovanligare att följa sidor. Att skapa innehåll som inbjuder till att samskapa och möjligheten att träffas utanför sociala medier visar på högt engagemang hos följarna i studiens kvantitativa undersökning. Implikationen är därför att användarna har blivit vana vid att innehållet riktas direkt till dem samt att det har hög kvalité och relevans. Innehåll utformas efter en specifik målgrupp som når dem vid rätt tidpunkt för att ge den ett så relevant innehåll som möjligt. Studien är begränsad till det sociala mediet Facebook och deras användare. Studien omfattar marknadsföring på Facebook via företagssidor. / Purpose – The purpose of this study is to give companies and organization's knowledge on how to create relevant content that interests their customers and how they can work with their marketing on Facebook.  Method – Methods used in this study are a qualitative study including interviews with experts in the field of marketing in social media. Furthermore, a quantitative study was made through measuring the interaction on three business sites on Facebook. Findings – Findings show that it is important to focus on the purpose and goal for the marketing, and what it will result in. Furthermore, it is not a goal itself to have high engagement. Today, the Facebook users are more anonymous online than earlier, and it has become unusual for them to follow a business site. Creating content that invites the users to co-create and to meet outside social media results in high interaction among the followers in the quantitative study. Lastly, continuous presence is required along with a genuine interest towards the costumers, and that the company gives their customer's attention. Implications – The implication is therefore that users have become more used to that content is directed directly towards them with a high quality and relevance. The content is designed for a specific target group that reaches them at the right time to give them as relevant content as possible. Limitations – The study is limited to the social media Facebook and its users. Furthermore, the study is focused towards marketing on Facebook for business sites.

This study will argue that visual art and the making of images share much With other languages. If writing can be deoonstructed, visual Imagery can be deconfigured, for figuring an image is much like structuring a sentence. The process of deconfiguration however relies on repetition. DeconflguratiOn therefore denies any claim of a primary creator. It will be argued though that deconfiguratlon remains creative as it engages the imagination in a process of transference and through association. Moreover, deconfiguration shows how binary opposites are essential In the making of artworks. The repetitive process takes place when the artwork Is made and continues during the appreciation and/or interpretation of the artwork. For the interpretation to really deconfigure, it would mean that the image constituted by the artist has metaphorical, allegorical and even symbolical implications. The interpreter will thus always remain a partidpant in the creative process suggested by the artwork. / Art History, Visual Arts & Musicology / M.A. (Visual Arts)

<p>Maximum asset performance is one of the major goals for electric power system managers. To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. One of the fundamental objectives is therefore to relate maintenance and reliability in an efficiently and effectively way, which is the aim of several maintenance methods such as the Reliability Centered Maintenance method (RCM). Furthermore, this necessitates the determination of the optimal balance between preventive and corrective maintenance to obtain the lowest total cost.</p><p>This thesis proposes methods for defining the importance of individual components in a network with respect to total interruption cost. This is a first step in obtaining an optimal maintenance solution. Since the methods consider several customer nodes simultaneously, they are especially suitable for network structures that serve many purposes/customers e.g. transmission and distribution networks with more than one load point. The major results are three component reliability importance indices, which are applied in two case studies. The first case study is based on a network in the Stockholm area. The second case study is performed for one overhead line system in the rural parts of Kristinehamn. The application studies demonstrate that the indices are possible to implement for existing electrical networks and that they can be used for maintenance prioritization. Consequently these indices constitute a first step in the overall objective of a maintenance optimization method.</p><p>The computations of the indices are performed both with analytical and simulation based techniques. Furthermore, the indices can be used to calculate the component contribution to the total system interruption cost. The approach developed for the importance indices can be utilized in any multi-state network that can be measured with one performance indicator.</p>

Malgré la diversité des recherches sur la parentalité adolescente, l'analyse des trajectoires parentales et des facteurs qui peuvent moduler l'effet de cet événement sur la scolarité demeure peu documentée. C'est précisément sur cet aspect que se penche la présente étude. L'objectif général de ce mémoire est de voir dans quelle mesure les différentes trajectoires adoptées par les jeunes parents sont associées à l’obtention des diplômes scolaires. Évidemment, les parents adolescents forment un groupe qui est plus à risque de ne pas avoir obtenu de diplôme secondaire vers 20 ans. Cependant, nous soutenons que la trajectoire parentale est différente pour chaque individu et qu'elle peut modifier la probabilité d’obtention des diplômes secondaire et postsecondaire. Les résultats des analyses de régression sur les données de l'Enquête auprès des jeunes en transition nous montrent que ce n’est pas le simple fait d’être parent qui influe sur la scolarité des jeunes, mais plutôt le type de trajectoires scolaires empruntées par ces derniers. Ainsi, certaines trajectoires parentales moins stables et plus précoces ont plus d’impact sur la non obtention d’un diplôme d’études secondaire, que les trajectoires parentales stables, qu’il s’agisse de monoparentalité ou de famille cohabitante. La précocité est donc un facteur d’influence différencié selon le type de parcours conjugal. De plus, nous observons que cette association entre certaines trajectoires parentales et l’obtention d’un diplôme s’observe également chez les hommes même si le type de trajectoire parentale est globalement moins explicatif que pour les femmes. Finalement, les variables reliées à la performance scolaire à 15 ans médiatisent en partie l’impact des trajectoires parentales sur le statut scolaire à 23 ans, ce qui suggère que l’association peut s’interpréter aussi comme un effet de la scolarité sur la parentalité. / Although many studies on teenage parenthood have been realized, little research examined the effect of parental trajectories on school graduation. The aim of this study is to better understand how teen parents' life trajectories influenced the probability of getting a diploma. Obviously, young parents have higher risk of not being graduated of high school before their 20 years old. However, we support that teen parents' life trajectories are different for each. In consequence the probability of getting a diploma can be modified. Based on data from the Youth in Transition Survey collected between 2000 and 2007, our results from regression analyses suggest that the simple fact of being a teenage parent does not explain all consequences on school graduation. The probability of getting a diploma would rather be influenced by teen parents' life trajectories. Additionally, results suggest that instable and early parenthood contribute to the likelihood of not being graduated at 23 years old. Our result shows that early parenthood has to be analyzed differently and a combination between precocity and instability help to better understand the effects of adolescent parenthood on diplomation. An association between academic performances at 15 years old and the level of education at 23 years old was also found, which may explain why this association may influences the probability of getting a diploma.

Qual o nível de conflito que torna uma crise intratável e resulta na cassação do mandato eletivo do prefeito pela Câmara Municipal? A literatura que se dedica a explicar esse fenômeno se divide em duas perspectivas: 1) variáveis sociais forçam os parlamentares a agir contra o incumbente e as variáveis políticas agem de forma complementar e, 2) fatores políticos levam os legisladores a forçar a saída do cargo do incumbente, com fatores sociais agindo de forma complementar. Em comum a essas duas perspectivas há o papel desempenhado pelo Legislativo como fator chave para a interrupção do mandato do chefe do Executivo. Esta pesquisa investiga sobre as causas determinantes da remoção dos prefeitos pelo parlamento municipal. Portanto, busca-se revelar são as variáveis institucionais e não institucionais que influenciam na motivação dos parlamentares que, diante de uma crise não assimilável, optam por cassar o mandato eletivo do prefeito a mantê-lo no cargo. A pesquisa utiliza dados coletados de 335 câmaras municipais paulistas sobre processos de cassação no período de 1992 a 2012 para trazer informações sobre a dinâmica do fenômeno no interior do Legislativo. Foram utilizados também dados do TSE e Seade das eleições municipais referentes a esse período. Essa base de dados original permite que testemos as principais explicações fornecidas pela literatura. O tema se insere dentro da literatura sobre remoção de presidentes, como um subgrupo desse fenômeno. Resultados das análises estatísticas descritivas apontam que o quadro de variáveis extraído dessa literatura apresenta um comportamento semelhante, em decorrência do desenho institucional do município que é simétrico ao ente federal, por força constitucional. Em conclusão, este estudo contribui com o debate que elucida os fatores que levam à ocorrência do fenômeno em questão, que pode ser entendido como um subgrupo da literatura que trata da remoção de membros do Executivo em diferentes instâncias. / What level of conflict makes a crisis intractable and results in the ousting of the mayor\'s elective term by the City Council? The literature that deals with understanding this phenomenon is divided into two opposing perspectives: 1) social variables force parliamentarians to act against the incumbent and the political variables act in a complementary way, and 2) political factors lead the legislators to force the incumbent out of office, with social factors acting in a complementary way. Both perspectives, however, share the understanding that the role played by the Legislative is a key factor for the interruption of the head of the Executive\'s mandate. This study investigates the determining causes of the removal of mayors by the local parliament. Thus, it aims at identifying the institutional and non-institutional variables that influence the motivation of parliamentarians who, faced with a crisis that is not assimilable, choose to remove the elective mandate of the mayor to keep him in office. The research uses data collected from 335 São Paulo municipal councils on ousting proceedings from 1992 to 2012 to provide information on the dynamics of the phenomenon within the Legislative. Data from the TSE and Seade of the municipal elections for this period were also used. This original database allows us to test the main explanations provided by the literature. The theme falls within the literature on the removal of presidents, as a subgroup of this phenomenon. Results of the descriptive statistical analyzes indicate that the variables extracted from this literature presents a similar behavior, due to the institutional design of the municipality that is symmetrical to the federal entity, by constitutional force. In conclusion, this study contributes to the debate that elucidates the factors that lead to the occurrence of the phenomenon in question, which can be understood as a subgroup of the literature that deals with the removal of members of the Executive in different instances.

"The next generation of aluminum alloys will have to operate at temperatures approaching 300°C. Traditional aluminum alloys cannot perform at these temperatures, but aluminum alloys reinforced with fine ceramic particles can. The objective of this research is to develop a process to synthesize Al-TiC composites by the Rotating Impeller Gas-Liquid In-situ method. This method relies on injecting methane into molten aluminum that has been pre-alloyed with titanium. The gas is introduced by means of a rotating impeller into the molten alloy, and under the correct conditions of temperature, gas flow, and rotation speed, it reacts preferentially with titanium to form titanium carbide particles. The design of the apparatus, the multi-physics phenomena underlying the mechanism responsible for particle formation and size control, and the operation window for the process are first elucidated. Then a parametric study that leads to the synthesis of aluminum reinforced with TiC microparticles and nanoparticles is described. Finally, potential technical obstacles that may stand in the way of commercializing the process are discussed and ways to overcome them are proposed. "

Porém, nos últimos anos, sob a direção da agência reguladora do setor, a ANEEL (Agência Nacional de Energia Elétrica), juntamente com especialistas, a área de qualidade da energia elétrica passou a receber uma atenção significativa, sendo legislada e adquirindo suas regulamentações iniciais. A área de Qualidade da Energia Elétrica passou, então, a formalmente existir e abranger um conjunto maior de fenômenos e eventos da rede elétrica. Em função dessa recente regulamentação, este trabalho apresenta o projeto de um medidor da qualidade da energia elétrica. Um dos focos do medidor é ser de baixo custo, tornando-o viável para o uso em grande escala. Este medidor é um sistema eletrônico que processa digitalmente os sinais de tensão da rede elétrica, extraindo os dados relacionados à qualidade da energia elétrica; tais dados são armazenados localmente e, posteriormente, acessados remotamente e enviados para um banco de dados, de forma que possam ser analisados. / Some years ago in Brazil the power quality was related, basically, with interruption of supplied energy and certain special loads of industry. In recent years, however, under controls of the regulating agency ANEEL (Agência Nacional de Energia Elétrica) and with specialists, the power quality area received the due attention and was legislated and acquired regulations. So, finally, the area of Power Quality was formally created and now it embraces several electrical phenomena and events. Because of the new regulations, this work presents a project of a power quality meter. One of meter s focuses is to be a low cost system and becomes able to be used in large scale. This power quality meter is an electronic system that processes the voltage signal of electrical network and extracts data related to power quality; the data are locally stored and after they are remotely accessed and transmitted to a data base to be analyzed.
