A partir da promulgação da Resolução CNE/CEB Nº 2, de fevereiro de 2001, indivíduos surdos obtiveram a oportunidade de ser integrados à escola básica ao receberem acesso aos conteúdos curriculares presentes no Plano Nacional de Educação (PNE). Desde então vem se buscando metodologias que ofereçam uma educação que atenda a esses alunos de forma adequada, alicerçada não somente na linguagem verbal e escrita, mas também na primeira língua do surdo, a Língua Brasileira de Sinais (LIBRAS). Diante do desafio de propiciar o ensino, principalmente em ciências, algumas alternativas foram selecionadas a luz da Pedagogia Visual, que tem como principal alicerce o argumento de que indivíduos surdos apresentam uma capacidade visual muito além daquela possuída pelo indivíduo ouvinte. A primeira alternativa, denominada \"Mapa Conceitual\", se adéqua a Pedagogia Visual por sua estrutura em moldes de diagrama, porém ainda possui uma base muito ligada a linguagem escrita, o que dificulta o aprendizado em alunos que ainda não possuem uma fluência na língua portuguesa, ou seja, ainda não são bilíngues. Outra dificuldade se encontra nos primeiros anos do ensino fundamental, em que alunos surdos ingressantes não apresentam fluência nem mesmo em LIBRAS, mas exibem um sistema particular de sinais apoiados na visão. Esse déficit pode ser contornado pela segunda alternativa, denominada de \"Modelo Qualitativo\" baseado em Raciocínio Qualitativo (RQ). O modelo qualitativo além de apresentar uma base gráfica que atende a pedagogia visual, trabalha com modelos de causalidade, emulando um sistema da forma mais real possível para que o aluno o compreenda. Para a construção do modelo foi usado um simulador denominado de DynaLearn, desenvolvido com o objetivo de integrar o aprendizado do aluno por meio de modelos qualitativos. Para que isso aconteça foram (I) desenvolvidos modelos qualitativos sobre Poluição Humana baseados em RQ, por meio do software DynaLearn, que atendessem aos Parâmetros Curriculares Nacionais (PCN) do 6º Ano do Ensino Fundamental, especificamente em relação ao ensino de ciências. Em seguida (II) o modelo foi aplicado no ensino de Ciências Naturais, em regime de contra turno, para uma turma de alunos surdos proficientes em LIBRAS, porém deficientes em Língua Portuguesa do Ensino Fundamental I, que posteriormente (III) teve seu aprendizado avaliado por meio de questionários e transcrições das aulas. Conclui-se que a aplicação do modelo qualitativo atingiu seus objetivos ao levar os alunos a desenvolverem o raciocínio qualitativo por meio da compreensão das relações causais, da mesma maneira que o software DynaLearn satisfaz os requisitos visualização requeridos pela Pedagogia Visual, destacando alguns pontos que podem melhorar devido ao público-alvo. Também foi observado que a aquisição de conceitos científicos pelos alunos apresenta relação íntima com seus sinais correspondentes. / Since the enactment of Resolution CNE/CEB No. 2, February 2001, deaf individuals had the opportunity to be integrated into the basic school to receive access to curriculum content present in the Plano Nacional de Educação (PNE). Since then has been seeking methodologies that provide an education that attends these students adequately grounded not only in verbal and written language, but also in the first language of the deaf, the Brazilian Sign Language (known as \"Libras\"). Faced with the challenge of providing education, especially in science, some alternatives were selected in view of Visual Education, whose main foundation the argument that deaf people have a visual capacity beyond that possessed by the individual listener. The first alternative, called \"Concept Map\" fits the Visual Pedagogy by your diagram templates structure, however still has a very connected based written language, which hinders learning in students who do not have fluency in Portuguese, that is, they are not bilingual. Another difficulty is in the early years of elementary school, where new deaf students do not have fluency even in \"Libras\", but show a particular system of signs supported in the vision. This deficit can be overcome for the second alternative, called \"Qualitative Model\" based on Qualitative Reasoning (QR). The qualitative model besides presenting a graphical basis that meets the visual pedagogy, works with causal models, emulating a system more real as possible so that the student understands. For the construction of the model was used a simulator called DynaLearn developed with the aim of integrating student learning through qualitative models. To make it happen were (I) developed qualitative models on Human Pollution based in RQ, through the DynaLearn software, which met the National Curriculum Parameters (NCP) of the 6th year of elementary school, specifically in relation to science teaching. Then (II) the model was applied in the teaching of Natural Sciences, in counter-shift system, to a group of proficient deaf students in \"Libras\" but deficient in Portuguese of the elementary school, which later (III) had their learning assessed by through questionnaires and transcripts lessons. It is concluded that the application of qualitative model reached these objectives by bringing students to develop the qualitative reasoning by understanding the causal relationships in the same way that the DynaLearn software meets the requirements of view required by Visual Education, highlighting some points that can improve due to the target audience. It was also noted that the acquisition of scientific concepts by students presents a close relationship with their corresponding signals.

This research explores leadership effectiveness in organisations in Kuwait from the perspective of Chief Executive Officers (CEOs). This is an area that has been neglected by the extant literature, and no integrated model for assessing CEO effectiveness exists for us to fully understand the phenomenon. Based on a positivist qualitative research approach, evidence was drawn from 16 CEOs using semi-structured interviews. The evidence was corroborated by using data obtained from participant observations of two CEOs working in the same organisation as the researcher. The results indicated that CEOs perceive leadership effectiveness as driving execution and not necessarily the realisation of goals themselves. Their experiences of leadership lead to CEOs in Kuwait believing that leadership effectiveness depends on their leadership style, relationship with the Board and the Executives, experience and family ground, societal and organisational culture, the business environment and CEO characteristics. On the basis of the participants’ perceptions of leadership effectiveness, it is recommended that CEO leadership development in Kuwait should focus on these areas, as this should equip CEOs to be effective in formulating clear visions and executing strategies to enable economic development of the country, and this should help them to compete globally. As the study focused on private and public companies, future research could consider CEOs from governmental and not-for-profit organisations to expand the sample of CEOs.

In spite of entrepreneur´s commitment in order to create the necessary conditions to ensure the survival of their enterprises, a remarkable lack of management skills to stabilish and coordinate the several processes and activities envolved, has led companies to unfavourable paths. In this sense, the concerns regarding the risks that naturally envolves any business activity are, almost always, neglected by ignorance. Risk is part of daily environment of business activities, and some are less impactful while others, if materializes, threats the longevity of the company. Therefore, a better understanding and control of the best pratices regarding risk management may contribute to a proper decision-making and ensure better results for the company. This work purposes to present and test a qualitative model of risk management designed for Brazilian non-financial small business. The company chosen to meet this case study is a Brazilian small company from service sector that operates in a franchising scheme. The results obtained, from company´s files review under the the assumptions of the proposed model, suggests the validation of this model on companies with this profile, and also shows managers and entrepreneus agreement regarding the necessity on implementing this management tools in a way to ensure the survival of the business. / Pesquisas realizadas por instituições ligadas às pequenas e médias empresas brasileiras, em particular, as não-financeiras, revelam que o índice de mortalidade tem sido elevado ao longo dos últimos anos. A despeito do empenho dos empreendedores em criar as condições necessárias para garantir a sobrevivência de suas empresas, a falta de capacidade gerencial, em geral, na organização dos vários processos e atividades, tem conduzido as empresas para caminhos pouco favoráveis. Neste sentido, a preocupação com os riscos que naturalmente permeiam os negócios de uma empresa são, quase sempre, por desconhecimento, desprezados ou relevados a um segundo plano. Risco é parte do dia-a-dia da existência das empresas, podendo alguns serem menos impactantes enquanto outros, se concretizados, ameaçar a longevidade da empresa. Desta forma, uma perfeita compreensão e domínio dos princípios e processos para uma gestão segura de riscos contribuirá para uma tomada de decisões adequada e para a garantia de melhores resultados para a empresa. Este trabalho tem como propósito apresentar e testar um modelo qualitativo de gestão de risco que possa ser utilizado por pequenas empresas não-financeiras brasileiras. A empresa escolhida para atender a este estudo de caso foi uma pequena empresa brasileira do setor de serviços que opera em regime de franchising. Os resultados obtidos, por meio de toda documentação apresentada à luz do modelo proposto, apontam para a adequabilidade do modelo em empresa deste gênero, bem como para a concordância por parte dos gerentes e do empreendedor quanto à necessidade de implantação deste tipo de gestão como forma de assegurar a sobrevivência da empresa.

Dans le cadre de la transition énergétique, le gouvernement Français prévoit la constructionde huit parcs éoliens en mer (offshore) le long des côtes Manche-Atlantique parmi lesquels le futurparc éolien au large de Courseulles-sur-mer. A ce jour, il n’existe pas d’étude globale et intégrée deseffets de la construction et de l’exploitation de ces parcs sur l’écosystème. L’innovation principale decette thèse a donc été de poser les bases d’une approche écosystémique des Energies MarinesRenouvelables (EMR) à travers l’exemple du futur parc éolien de Courseulles-sur-mer. Pour ce faire,une combinaison d’outils de modélisation a été utilisée afin de : 1) caractériser le fonctionnement etla structure de l’écosystème du site d’implantation du parc ; 2) tester des scénarios d’évolutionpossible du fonctionnement trophique du système. Ainsi, un modèle de réseau trophique et troisscénarios ont été construits afin d’analyser les conséquences de l’effet récif et réserve générées par leparc sur l’écosystème. Les indices de l’analyse des réseaux écologiques ainsi que d’autres indices telsque le niveau trophique moyen ont été analysés afin de caractériser le fonctionnement du système.Toutefois, conscient que cet écosystème est menacé par de multiples pressions, il estnécessaire de comprendre comment ces activités humaines vont interagir entre elles et quelles sontleurs conséquences sur l’écosystème dans un contexte de changements globaux. Ainsi, une visionglobale des impacts cumulés a également été développée grâce à un autre type de modélisation appelé'modélisation qualitative’ ou en ‘digraphe orienté’. Les résultats ont mis en évidence des changementsdans la structure et le fonctionnement de l’écosystème après la mise en place du parc éolien. Lesrésultats de ces modèles pourraient être utilisés dans la définition de mesures de suivi aprèsl’installation du parc et dans l’évaluation de la nécessité de mettre en place des mesures decompensation. Enfin, les modèles qualitatifs pourraient également servir d’outils de communicationavec le public et ainsi permettre une meilleure appropriation des projets EMR. / As part of the energy transition, the French government is planning the construction of eightOffshore Wind Farms (OWF) along the English Channel and Atlantic coasts including the Courseulles-sur-mer OWF. Until now, there is no holistic study on the OWF construction and operation effects onan ecosystem taken as a whole. This thesis is the first study to lay the foundations for an ecosystemapproach of Marine Renewable Energy (MRE) through the Courseulles-sur-mer OWF example. For thata combination of innovative modelling tools was applied to 1) characterise the ecosystem structureand functioning before the OWF construction; 2) simulate the impacts of this future OWF on theecosystem structure and functioning. A food-web model and three scenarios were constructed toinvestigate the “reef” and “reserve” effects induced by the OWF on the ecosystem. Ecological NetworkAnalysis indices, other ecosystem attributes and Mean Trophic Level were derived to investigate theecosystem health and state.However, being aware that this ecosystem is threatened by multiple perturbations, there is aneed to understand how human activities interact to influence ecosystem functioning in a long termclimate change context. Thus, a holistic view of cumulated impacts on the Courseulles-sur-mer’ecosystem through the use of an oriented signed digraph was also developed. Results highlighted acombination of significant changes in the food-web structure and ecosystem functioning. These resultscan play a vital role in both decision making by improving long term planning for the marineenvironment but also as tool for communication with the public and so contribute to a betteracceptability of MRE project.

Cities and districts contribute to a large fraction of the total energy consumption in Sweden. The residential- and service sector accounted for almost 40% of the total energy consumption in 2018. The increasing urbanization also puts more importance on the energy supply, distribution and consumption in these areas. One way of planning an energy system in urban areas is to have integrated energy systems where synergies between different technologies and energy carriers are utilized. Such a solution can increase the flexibility of the energy system and thus help integrate more intermittent renewable energy sources. The aim of this study was to suggest tools for planning energy systems in districts. This was done by performing a literature review regarding the design of energy systems and the identification of barriers and opportunities for the integration of different production- and distribution technologies. The focus was on systems for heating, cooling and electricity. The proposed tools are three Excel-based modules. The first module is a qualitative model that presents the reviewed technologies and their connections. It also includes synergies between different energy carriers and sectors for consumption and production. The second module is qualitative model related to market mechanisms, juridical, organizational and institutional aspects. The third module is a table containing the barriers and opportunities. Furthermore, relevant stakeholders are identified to be district heating companies, building owners, joint associations, municipalities, district cooling companies and photovoltaic plant owners. The proposed tools can be used in the first stage of planning when the technologies are selected. To show how the suggested tools can be applied, a case study was performed. The study case is a district being planned in Stockholm, Sweden. For the analysis, a model for a hypothetical heating system was required. Two models were developed for the heat supply system using the modelling environment OpenModelica. The main objective of the case study was to compare the techno-economic and environmental performance of different scenarios. Three different scenarios were considered for covering the total heating demand in the district. In the first scenario the total heating demand is covered only by local heat pumps. In the second scenario the space heating demand is covered by heat pump(s) coupled with a thermal energy storage (hot water tank). An electric boiler is used as backup. In the third scenario, the electric boiler is replaced by district heating as backup. A sensitivity analysis was included for different numbers of heat pumps and different sizes of thermal energy storage in the two last scenarios. The economic and environmental results in this study were strongly dependent on the assumptions regarding prices and emission factors. The result of the case study indicates that the third scenario causes the lowest CO2 emissions. An increased size of the thermal energy storage causes a higher compressor electricity consumption thus more emissions. However the total emissions from the system depends on the backup component. For this result, the emission factor related to Swedish electricity mix and the emission factor stated by a district heating company in Stockholm was used. The cheapest alternative in terms of annual operational cost of energy is the first scenario with only heat pumps. However, from the scenarios which also includes thermal energy storage, the second scenario with three heat pumps and a 100 m3 large thermal energy storage, presents the lowest cost. This system design in scenario 2 is only 0.6% more expensive than the first scenario. For the energy prices, the assumption for electricity is based on hourly values from Nordpol and for heat, the values presented in a normal price list from a district heating company is assumed. Regarding the technical performance of the system the result indicates that the contribution from the thermal energy storage as it is modelled in this case study is not significant on anannual basis. However it is observed that a larger thermal energy storage unit covers a higher fraction of the power demand during the hours it is utilized. / Städer och stadsdelar står för en stor del av totala energikonsumtionen i Sverige. Bostads- och servicesektor stod för ungefär 40% av totala energikonsumtionen under 2018. Den ökande urbaniseringen lägger också mer vikt vid energiproduktion, distribution och konsumtionen i dessa områden. Ett alternativ för planering av energisystem i urbana områden är att ha integrerade energisystem där synergier mellan olika teknologier och energibärare kan utnyttjas. Den typen av system skulle kunna öka flexibiliteten i energisystemet och därför förenkla integrering av oförutsägbara förnybara energikällor. Syftet med denna studie var att föreslå verktyg för planering av energisystem i stadsdelar. Detta gjordes genom en litteraturstudie angående utformningen av olika energisystem samt identifiera hinder och möjligheter för att integrera olika produktions- och distributions teknologier. Fokus låg på systemen för värme, kyla och elektricitet. Det föreslagna verktygen är tre Excel baserade moduler. Den första modulen är en qualitative modell som presenterar de studerade teknologier och deras kopplingar. Den innehåller också synergier mellan de olika energibärarna och konsumtions- och produktionssektorn. Den andra modulen är en qualitative modell, men relaterad till marknad mekanismer, juridiska, organisatoriska och institutionella aspekter. Den tredje modulen är en tabell som beskriver hinder och möjligheter för några av teknologierna. Utöver det de relevanta aktörerna identifierades. För värme-, kyla- och elektricitet marknaden är de fjärrvärmeföretagen, fastighetsägare, samfälligheter, kommuner, fjärrkyla företagen, solcells ägare. De föreslagna verktyget kan användas för planering av energisystem i ett första skede när teknologier ska väljas.  En fallstudie genomfördes för att visa hur det föreslagna verktyget kan användas. Fallstudien en stadsdel som planeras i Stockholm, Sverige. För att genomföra en analys behövdes en modell för ett hypotetiskt värmesystem. Två modeller utvecklades för värmesystemet genom att använda modelleringsmiljön OpenModelica. Det huvudsakliga målet med fallstudien var att jämföra den teknoekonomiska- och miljöinriktade prestandan för olika scenarierna. Tre olika scenarier övervägdes för att täcka totala värmebehovet i stadsdelen. I det första scenariot täcks det totala värmebehovet endast av lokala värmepumpar. I andra scenariot täcks värmebehovet för uppvärmning av värmepump(ar) kopplade till en värmelagrings komponent (ackumulatortank). En elpanna användes för reserveffekt. I tredje scenariot är elpannan ersatt av fjärrvärme. En känslighetsanalys var utförd för olika antal värmepumpar kopplade till olika storlekar av värmelagrings-komponenten i de två sista scenarierna. De ekonomiska och miljörelaterade resultatet i den här studien är starkt beroende av antaganden gällande priser och utsläppsfaktorer. Resultatet indikerar att det tredje scenariot har de lägsta CO2 utsläppen. Ökad värmelagringsstorlek bidrar till att värmepumpen förbrukar mer elektricitet och därför ökar de relaterade utsläppen. Däremot beror de totala utsläppen i systemet på vilken reservkraft som används. För dessa resultat användes utsläppsfaktorn för svensk elmix samt utsläppsfaktorn från ett fjärrvärme företag i Stockholm. Den billigaste alternativet gällande årlig driftsenergikostnad är det första scenariot med endast värmepumpar. Däremot, bland de scenarion som innehåller värmelagring, har det andra scenariot med tre värmepumpar och 100m3 stor värmelagringsenhet den lägsta kostnaden. Detta system är endast 0.6% dyrare än det första scenariot. För energipriser har timvärden från Nordpol antagits för elektricitet och för värme har normalprislistan från ett fjärrvärmebolag i Stockholm antagits. Angående den tekniska systemprestandan, indikerar resultatet att bidraget från värmelagringsenheten som den är modellerad i den här fallstudien inte är signifikant på årsbasis. Det observeras emellertid att en större värmelagringsenhet täcker en större andel av effektbehovet under de timmar som enheten används.
