Modelos matemáticos são representações ou interpretações simplificadas da realidade ou uma representação de um fragmento de um sistema. As simulações destes fenômenos auxiliam na tomada de decisão da parte interessada, ou seja, aqueles que trabalham em uma área. A modelagem de um sistema de processos anaeróbios, como o tratamento de um efluente em reatores UASB (Upflow Anaerobic Sludge Blanket), auxilia os gestores destes sistemas na operação e no controle de estabilidade. O modelo ADM1 (Anaerobic Digestion Model Nº 1), criado pela IWA em 2002, simula o comportamento da digestão anaeróbia. Entretanto, este modelo não considera a hidrodinâmica do sistema como fator relevante no desempenho do processo. O estudo do comportamento do escoamento de efluente no interior de um reator é possível através de ensaios de hidrodinâmica. Estes são conduzidos, majoritariamente, por meio de experimentos laboratoriais que se utilizam de traçadores que, por sua vez, podem resultar em custos elevados. A Dinâmica de Fluidos Computacional (DFC) é uma área na mecânica dos fluidos que utiliza análises numéricas e algoritmos para solucionar e analisar problemas relacionados com escoamento de fluidos. Os softwares de DFC que resolvem estes algoritmos podem ser utilizados na simulação dos ensaios de hidrodinâmica. Foi utilizado nesta tese o pacote de DFC Ansys®, em que o software CFXTM foi o escolhido para realizar as simulações de escoamento. Um dos objetivos desta tese foi a validação desta simulação por meio de ensaios de laboratório e ensaios virtuais em um reator UASB em escala de bancada (1,5 L). Resultou-se, dessa comparação, em dados estatisticamente similares (teste U de Mann-Whitney), proporcionando validação do método. Após esta validação, simulou-se o mesmo tipo de ensaio para um reator UASB em formato de \"Y\" (escala piloto; 119,3 L). Foram simuladas três condições operacionais, em que se variou a vazão de alimentação, sendo esta função da carga orgânica volumétrica aplicada ao lodo (COV). As COV foram 7,5, 12,5 e 17,5 kgDQO m-3d-1. Obteve-se N-CSTR (número de reatores de mistura completa em série) igual a 11, 10 e 10 unidades para cada condição, respectivamente. A ferramenta de Dinâmica de Sistemas utiliza-se de uma abordagem de entendimento de modelos complexos e, por meio de ciclos de retroalimentação (feedback) e estoques e fluxos (stocks and flows), demonstra que modelos aparentemente simples podem ser muito complexos. Existem vários softwares de Dinâmica de Sistemas e neles podem ser implementados os mais variados modelos. Utilizando o software Vensim PLE®, modelou-se a digestão anaeróbia do ácido acético por meio de equações baseadas no modelo de cinética enzimática de Monod e no modelo de digestão anaeróbia ADM1. Considerou-se as taxas de consumo de substrato e crescimento de biomassa bacteriana, a inibição causada pelo pH e a quantidade de alcalinizante necessária para atingir o pH desejado deste meio. De forma complementar, integrou-se um modelo de cálculo de alcalinidade do meio e, desta forma, foi possível determinar as concentrações de cada espécie que confere alcalinidade ao meio, considerando o equilíbrio do carbonato. Denominou-se esta modelação (DFC e dinâmica de sistemas) de Modelo Hidro-bioquímico do processamento anaeróbio. Os resultados obtidos por Del Nery et al. (2016) corroboraram com os obtidos nesta tese. / Mathematical models are representations and simplified interpretations of reality or a representation of a system fragment. The modeling of anaerobic processes, such as wastewater treatment in UASB (Upflow Anaerobic Sludge Blanket) reactors, helps managers in the operation of these systems and stability control. The Anaerobic Digestion Model No. 1 (ADM1), created by IWA in 2002, simulates the behavior of anaerobic digestion. However, this model does not consider the system hydrodynamics as a relevant factor in the performance of the process. The effluent flow behavior studies on the reactor inside is possible by hydrodynamic tests. These are conducted through laboratory experiments that uses tracers and this can result in high costs in the conduct of the tests. The Computational Fluid Dynamics (CFD) is an area in fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems related to fluid flow. CFD software can be used to simulate the hydrodynamics assays. It was used in this thesis Ansys® workbench, wherein the CFXTM software was chosen to perform CFD flow simulations. One objective of this thesis was to validate the CFD simulation through laboratory and virtual testing in a UASB bench scale (1.5 liters). In this comparison, it resulted in similar data statistically (Mann-Whitney U test). After validation of the hydrodynamic test, was simulated the same type of assay for an UASB reactor \"Y\" shaped (pilot scale; = 82.27 liters working volume). The test result was N-CSTR (number of complete mixing reactors in series) equal to 4 units, considering a 103.9 liters per day of feed flow (hydraulic retention time of 19 hours). The system dynamics tool makes use of understanding approach of complex models and, through feedback loops and stocks and flows, shows that seemingly simple models can be very complex. There are several system dynamics software and most varied models can be implemented. Using Vensim PLE® software, it was developed an acetate anaerobic digestion model (in this case acetic acid) via equations based on the Monod and ADM1 model. It was considered for the hydro-biochemical modeling, substrate consumption and growth of bacterial biomass rates, the pH inhibition and the amount of alkalizing necessary to achieve the desired pH of the medium. Complementarily, integrated into a calculation alkalinity model of the medium and thus it was possible to determine the concentrations of each species imparts environment alkalinity, considering the carbonate balance.

Para muitas empresas o Supply Chain tem se tornado um fator crítico para ganhar vantagem competitiva nos mercados e um relevante alvo para a estratégia. Esta dissertação de mestrado teve por objetivo identificar a proposição estratégica e o delineamento da estrutura de processos utilizados na condução de um modelo integrado de gestão de Supply Chain e analisar as contribuições do modelo SCOR ao contexto da empresa estudada. A estratégia de pesquisa utilizada foi o estudo de caso de caráter exploratório em uma empresa que oportunizasse a geração de evidências a partir de seu modelo de gestão. Inicialmente foi realizada a pesquisa documental, a fim de identificar o contexto organizacional, elencando os eventos ocorridos, a organização dos processos que suportam o modelo integrado de gestão, e a motivação organizacional e estratégica que levaram à criação da função do Supply Chain. Através da análise de conteúdo em categorias que abordavam temas como estratégia, desempenho e modelo integrado de Supply Chain, identificou-se o alinhamento entre as estratégias e iniciativas do Supply Chain, as proposições de desempenho e o conceito de criação de valor do negócio, e o realinhamento da estrutura funcional num conceito integrado de processos suportados por práticas e uma visão estendida de atuação. Tendo como base a pesquisa documental e análise de conteúdo, foram recomendadas contribuições com base no SCOR ao modelo atual de gestão de Supply Chain da empresa estudada, visando colaborar na evolução do modelo integrado atual de gestão do Supply Chain. A utilização do SCOR para análise das operações de Supply Chain e modelo integrado de gestão se justifica por entender que não seria possível realizar os posicionamentos e contribuições acerca das operações do Supply Chain sem a utilização de um modelo conceitual e de processos como referência. Com o estudo de caso realizado foi possível identificar que o Supply Chain passou a ser visto de forma estratégica quando ocorreu o alinhamento da gestão do Supply Chain com os objetivos do negócio e a partir da definição do Supply Chain como uma competência essencial à competitividade da empresa, desenvolvendo uma organização de processos e estrutura que suportasse a estratégia proposta. / The level of importance given to processes under Supply Chain responsibility has increased in the last few years. For many companies the Supply Chain has become a critical factor when it comes to achieving competitive advantage in the markets and a rather relevant target for strategy. This master’s dissertation had the objective to identify the strategy proposition and the outline of the structure of processes used to build a Supply Chain integrated model of management as well as to analyze the contributions of the SCOR model towards the context of the researched company. The research strategy used herewith was an exploratory case study within a company that would provide the means for evidence from its management model. A documentary research was firstly carried out so as to identify the organizational context, listing the events that took place, the organization of the processes that support the integrated management model and the organizational and strategic motivation that led to the setup of the Supply Chain footprint. It was possible to identify the strategies and Supply Chain initiatives alignment through the analysis of content in categories that covered issues such as strategy, performance and integrated supply chain model, performance propositions and the concept of business value, and the realignment of the functional structure within an integrated concept of processes supported by practices and an extended vision of performance. Based on the documentary research and content analysis some contributions were recommended having the SCOR model applied to the current supply chain management model of the company analyzed, with the intention of collaborating with the improvement of the current integrated supply chain management model. The SCOR model analysis of Supply Chain operations and integrated management model is justified because it would not be possible to defend a position and offer contributions to Supply Chain operations without using a conceptual model or processes as reference. This case study allowed for the observation that Supply Chain started to be viewed in a strategic way when the Supply Chain management and business objectives alignment took place and from the definition of Supply Chain as an essential competence to the company’s market competition, developing an organization of processes and structure to support the proposed strategy.

This work examines the learning outcomes of a French professional development program for science education in primary school, ASTEP. The program is based on a partnership between a primary school teacher on one hand and a subject expert on the other. Its uniqueness lies in the fact that the subject expert is a young university student who is challenged to be assessed on his/her learning for academic credits. Compared to most other professional development programs, ASTEP displays an alternative knowledge hierarchy, it is neither top down nor bottom up, but rather a form of knowledge exchange. Data on students´ and teachers´ reflections on the collaboration were analyzed through a grounded theory approach and subsequently organized within the interconnected model of teacher professional growth (IMTPG). Although the analyses indicated significant changes in the practice of the teachers, the learners who individually seem to benefit the most were the university students. The ASTEP program appears to provide a low stake high support scaffold for the students to refine their values and beliefs about a professional life and develop a professional identity.

Product success is a major goal of designing and design research. Designing involves developing systems. A system interacts with its environment to satisfy its requirements. Therefore, designing should involve developing the concept of both the system and its surrounding. Depending on how the concept of the system changes will impinge on the concept of the environment, and vice-versa; design must co-evolve the concepts of both the system and its environment to adapt them to each other. A comprehensive review of literature on designing to explore the use of system-environment view in designing revealed that while the concept of systems is used by many design models, implicitly or explicitly, the concept of environment is rarely used as an evolvable construct in designing. Activities, outcomes, requirement-solution and system-environment views play a significant role in product success. Thus, it is important to explicitly address these views in designing. Further, integration of these views is important for explaining various complex characteristics of designing such as requirement-solution co-evolution and system-environment co-evolution. Integration of views is important also for mapping the steps in design models using these views, so as to be able to characterize design models, or benchmark one design model against another. Literature has been reviewed to identify the constructs in these views that are essential for representing the design process. Srinivasan and Chakrabarti [2010] had earlier developed a model of designing by integrating three of these views: activities, outcomes, and requirement-solution. However, this model did not incorporate the system-environment view. In this thesis, a system-environment view is developed, with both the system and environment as explicit and evolvable constructs in designing. The thesis then proposed an extended, integrated model of designing which combines the constructs of the identified views of activities, outcomes, requirement-solution and system-environment. The proposed model is empirically validated using protocols from six design sessions; the sesessions had been undertaken well before the proposed model was developed.Validation involved checking whether or not instances of all the constructs in the model are naturally present in these design sessions, and whether or not every event in these design sessions could be described using the constructs of the proposed model. Further, the explanatory power of the proposed model is illustrated by explaining how system-environment co-evolution and requirement-solution co-evolution occur during the design sessions captured in the protocols. Also, a standard prescriptive approach to designing –Pahl and Beitz approach – is used to demonstrate how a design model can be mapped using the constructs of the proposed model–the first step to characterizing or benchmarking design models.

The purpose of this thesis is to develop and test the Advanced Integrated Model, a typological model in the tradition of Weber’s interpretive sociology, as an asset in explaining recent transformations in American Episcopal-Anglican organizations. The study includes an assessment of the church-sect tradition in the sociology of religion and a summary overview of Weber’s interpretive sociology with special emphasis on the nature and construction of idealtypes and their use in analysis. To illustrate the effectiveness of the model a number of institutional rivalries confronting contemporary Episcopal-Anglican organizations are identified and shown to be explainable only from a sociological perspective and not simply as “in house” institutional problems. The present work sheds light on parent-child conflicts in religious organizations and reopens discussion about the theoretical value of ideal-types in general, and church-sect typologies in particular, when utilized from a comparative-historical perspective

Alternativ splicing av pre-mRNA ger upphov till proteindiversitet. Histonmodifieringar kopplas till den alternativa splicingens reglering genom adaptorsystem som overfor den epigenetiska informationen direkt till splicingfaktorerna. De cis- agerande RNA- elementen pa exoner och introner med tillhorande trans- reglerande splicingfaktorer paverkas darfor direkt av specifika histonmodifieringar. En sammankopplande integrerad modell over en rad DNA- baserade processer foreslas. Denna komplexa modell ger en bild av interaktioner och paverkan mellan dessa delar. Kromatin remodellering kravs for bildandet av eukromatin. Nukleosomers placering vid exonrika regioner med specifika modifieringsmonster pekar ut exonerna samt mojliggor inbindning av RNA polymeras II som med sin CTD doman rekryterar bade splicing- och modifieringsfaktorer. Transkriptionshastigheten paverkas av nukleosomplaceringen vilket i sin tur paverkar rekrytering av spliceosomens komponenter, andra trans- agerande regulatorer och aven pre-mRNA sekvensens sekundarstruktur. Kromatin- adaptorkomplex laser av specifika histonmodifieringar och overfor informationen till splicingapparaten. Detta skapar mojlighet till den viktiga cell- och vavnadsspecifika alternativa splicingens reglering. I den integrerade modellen blir komplexiteten tydligare dar alla dessa processer interagerar med varandra och de cis- regulatoriska sekvenserna pa premRNA transkriptet. / Alternative splicing of pre-mRNA generates protein diversity. Histone modifications are connected to the regulation of alternative splicing through adaptor systems that transfers the epigenetic information directly to the splicing factors. The cis- acting RNA elements on the exons and introns together with the trans- regulating splicing factors are therefore directly affected of specific histone modifications. An integrated model over several DNA process mechanisms is suggested. This complex model explains the interactions of the different parts and how they affect each other. Chromatin remodelers are required to obtain euchromatin. Nucleosome positioning at exon rich regions with a specific modification pattern point out where the exons are, and this enable the RNA polymerase II to find and bind to the DNA. It’s CTD domain recruits both splicing- and modifications factors. The transcription rate is also affected of the nucleosome positioning and that in turn affects the recruitment of the components of the spliceosomen, other trans- acting regulators and even the formation of the secondary structure of the pre-mRNA transcript. Chromatin- adaptor complex reads specific histone modifications and transfers this information to the splicing apparatus. All this creates the possibility to regulate important cell- and tissue specific alternative splicing patterns. The integrated model makes the complex processes more clearer when all these integrates with each other and the cis- acting regulating elements on the pre-mRNA transcript.

This PhD thesis explored the experiences of dependent children and children care-givers facing challenges with their parent s cancer. The aim was to understand children s information experience including their perception of cancer and information culture; information needs, information seeking behaviour, barriers and enablers. The research used a six-stage process. This was informed by an extensive literature review and discussions with cancer specialists, psychologists and researchers from United Kingdom, United States, Australia and Malaysia. This study used a three-cycle, eight-step process of Participative Action Research (PAR) with participation from ten Malay breast cancer patients and their dependent children. Three bilingual (English and Bahasa Malaysia) instruments were developed; 1) An Inquiry to Participate Form to select participants who had dependent children, 2) Three opened-ended questions to obtain children s cancer experience and information needs where drawing was used to encourage children s responses and, 3) A 15-question questionnaire to understand children s experience and information preference. Cancer affected parenting abilities and challenging experiences identified the lack of culturally relevant information and the shift in caregiving responsibilities to dependent children. Children s understanding of cancer was influenced by their experiences and observations, many of which resulted in misconceptions about cancer, its causes, treatment and preventative measures. Children participant s reaction to a health situation triggered their information behaviour. The burden of caregiving and the consequences of a lack of information were greater than anticipated; children had many dimensions of concern and experienced many challenges. This advocated for a more assessable, attractive and sensitive information system. Data synthesis contributed to the development of a Children s Reactive Information Seeking Behaviour An Integrated Model that seeks to explain the relationship between children participants reaction to a health situation and the subsequent processes they undergo to resolve their state of information need.

Text in English / Developments in Internet technology and pervasive computing over the past two and half decades have resulted in a variety of Web-based applications (WBAs) that provide products and services to online users or customers. The Internet is used not only to transfer information via the web but is increasingly used to provide electronic services including business transactions, information-delivery and social networking, as well as e-government, e-health and e-learning. For such organisations, e-service quality, usability and user experience are considered to be critical determinants of their products’ or services’ success. Many studies to model these three concepts separately have been undertaken as part of broader studies of software quality or service quality modelling. However, to the current researcher’s knowledge, none of the studies have focussed on proposing an evaluation model that integrates and combines the three of them. This research is an effort to fill that gap. The primary purpose of this mixed-methods research was to develop a conceptual integrated model for evaluating e-service quality, usability and user experience (e-SQUUX) of WBAs and then contextualise it to evaluation of a University web portal (UWP). This was undertaken using an exploratory sequential research design. During a qualitative phase, an extensive extensive systematic literature review of 264 relevant sources relating to dimensions of e-service quality, usability and user experience, was undertaken to derive an integrated conceptual e-service quality, usability and user experience (e-SQUUX) Model for evaluating WBAs. The model was then empirically refined through a sequential series of validations, thus developing various versions of the e-SQUUX Model. First, it was content validated by a set of four expert reviewers. Second, during the quantitative phase, in the context of a University web portal, a questionnaire survey was conducted that included a comprehensive pilot study with 29 partipants, prior to the main survey. The main survey data from 174 particiapants was used to determine a validated model, using Exploratory factor analysis (EFA), followed by producing a structural model, using partial least square – structural equation modelling (PLS-SEM). This version consisted of the components of the final e-SQUUX Model. Consequently, the research enriches the body of knowledge on IS and HCI by providing the e-SQUUX Model as an evaluation tool. For designers, developers and managers of UWPs, the model serves as a customisable set of evaluation criteria and also provides specific recommendations for design. In line with the Exploratory sequential design of mixed methods research, the findings of the qualitative work in this research influenced the subsequent quantitative study, since the potential Likert-scale questionnaire items were derived from the definitions and meanings of the components that emanated from the qualitative phase of the study. Consequently, this research is an exemplar for developing an integrated evaluation model for specific facets or domains, and of its application in a particular context, in this case, a University web portal.
