Dissertations / Theses on the topic 'Holistic approach to treatment'

Provoked vulvodynia (PVD) is a disorder characterized by intense vulvar pain, most often reported as raw, burning, or stinging tissue. Current treatment options for PVD are insufficient and narrow in focus, as they predominantly address the physical pain associated with the disorder. Current publications regarding cognitive behavioral therapy and mindfulness treatment indicate that both therapies are highly effective. Mindfulness and cognitive behavioral therapies are noninvasive, efficacious long term, and provide a comprehensive biopsychosocial approach. The aim of this study is to educate nurse practitioners regarding these treatment options, which manage the physical as well as psychosocial aspects of PVD.

Clinicians have a wide-variety of therapy materials, activities, techniques, and procedures available for treatment of children with morphosyntax deficits. This clinically-focused article describes strategies that highlight the critical features of morphosyntactic targets, reviews, techniques, and procedures available to clinicians for their mindful use, and advocates for the addition of distributed learning in daily contexts by involving caregivers in language facilitation. It concludes with a proposal for a holistic approach that encompasses three levels of language intervention. At the first level, the clinician overtly primes the child's system; at the second level, the clinician sets up multiple opportunities to use the target in context; at the third level, the clinician engages caregivers as agents of intervention for distributed learning and sends the child out into a language-facilitating environment.

The process of allocating necessary resources like clean water, fuel/energy and food have resulted in an unsustainable use of natural resources causing problems with Soil erosion, soil fertility, desertification, deforestation, eutrophication and global warming. The purpose of this study was to gain information on the functional design of a waste management system enabling the organic components of domestic waste to be processed as useful resources while at the same time allow them to be re-circulated. The main part of this study was carried out at the Kendu SDA Hospital in the Rachyonyo district in western Kenya. For the case of this study two main objectives where chosen. The first was to develop a principal technological solution using three classed “appropriate technologies” found suitable for the purpose namely biogas, ecological water treatment systems and slow sand filtration. The second was to further analyse each included technology to further develop their potential to fit the concept. Results from the pilot facilities where then to be retrieved from the actual component selection and construction process itself, with performance analysis left for future studies.

The main purpose of the biogas system study has been to evaluate the original ideas of overall concept, details, materials and construction methods. The 1 m3 biogas system has improved significantly during the development process and is today not far from an implementation, i.e. construction on a slightly larger scale. The biogas system developed during the project has proven to have potential for digestion of both latrine and kitchen waste. Using the two as fuel for the process does not only remove a problem – it grants several benefits.

The ecological waste water treatment system main objective was to design and construct a pilot SSF-wetland. Results show that the construction process for smaller scaled SSF systems is simple and does not require trained personnel or specialized equipment and that significant cost reduction can be made by using locally available materials.

The slow sand filtration sub system concept is called PT SCX and though still in the stage of development proved to have great potential concerning both efficiency and sustainability. The PT SCX comprises the advantages of slow sand filtration with further development of individual system solutions. It was adapted to enable both integration to the IWESS solution and stand alone installations purifying even highly turbid surface water sources to drinking water quality.

The result from the study confirms the suitability of the three included technologies, ecological waste water treatment, biogas and slow sand filtration to work in an integrated system called IWESS- Integrated Water Energy and Sanitation Solution. The combined subsystems can together with source separated sewage offer full resource recovery enabling recirculation of both nutrients and water. In addition the system can be designed as a net producer of renewable and emission free energy.

Doutoramento em Engenharia Informática
Em sistemas distribuídos o paradigma utilizado para interacção entre tarefas é a troca de mensagens. Foram propostas várias abordagens que permitem a especificação do fluxo de dados entre tarefas, mas para sistemas de temporeal é necessário uma definição mais rigorosa destes fluxos de dados. Nomeadamente, tem de ser possível a especificação dos parâmetros das tarefas e das mensagens, e a derivação dos parâmetros não especificados. Uma tal abordagem poderia permitir o escalonamento e despacho automático de tarefas e de mensagens, ou pelo menos, poderia reduzir o número de iterações durante o desenho do sistema. Os fluxos de dados constituem uma abordagem possível ao escalonamento e despacho holístico em sistemas distribuídos de tempo-real, onde são realizadas diferentes tipos de análises que correlacionam os vários parâmetros. Os resultados podem ser utilizados para definir o nível de memória de suporte que é necessário em cada nodo do sistema distribuído. Em sistemas distribuídos baseados em FTT, é possível implementar um escalonamento holístico centralizado, no qual se consideram as interdependências entre tarefas produtoras/consumidoras e mensagens. O conjunto de restrições que garante a realização do sistema pode ser derivado dos parâmetros das tarefas e das mensagens, tais como os períodos e os tempos de execução/transmissão. Nesta tese, são estudadas duas perspectivas, uma perspectiva centrada na rede, i.e. em que o escalonamento de mensagens é feito antes do escalonamento de tarefas, e outra perspectiva centrada no nodo. Um mecanismo simples de despacho de tarefas e de mensagens para sistemas distribuídos baseados em CAN é também proposto neste trabalho. Este mecanismo estende o já existente em FTT para despacho de mensagens. O estudo da implementação deste mecanismo nos nodos deu origem à especificação de um núcleo de sistema operativo. Procurou-se que este introduzisse uma sobrecarga mínima de modo a poder ser incluído em nodos de baixo poder computacional. Neste trabalho, é apresentado um simulador, SimHol, para prever o cumprimento temporal da transmissão de mensagens e da execução das tarefas num sistema distribuído. As entradas para o simulador são os chamados fluxos de dados, que incluem as tarefas produtoras, as mensagens correspondentes e as tarefas que utilizam os dados transmitidos. Utilizando o tempo de execução no pior caso e o tempo de transmissão, o simulador é capaz de verificar se os limites temporais são cumpridos em cada nodo do sistema e na rede.
In distributed systems the communication paradigm used for intertask interaction is the message exchange. Several approaches have been proposed that allow the specification of the data flow between tasks, but in real-time systems a more accurate definition of these data flows is mandatory. Namely, the specification of the required tasks’ and messages’ parameters and the derivation of the unspecified parameters have to be possible. Such an approach could allow an automatic scheduling and dispatching of tasks and messages or, at least, could reduce the number of iterations during the system’s design. The data streams present a possible approach to the holistic scheduling and dispatching in real-time distributed systems where different types of analysis that correlate the various parameters are done. The results can be used to define the level of buffering that is required at each node of the distributed system. In FTT-based distributed systems it is possible to implement a centralized holistic scheduling, taking into consideration the interdependences between producer/consumer tasks and messages. A set of constraints that guarantee the system feasibility can then be derived from tasks and messages’ parameters such as the periods and execution/transmission times. In this thesis the net-centric perspective, i.e., the one in which the scheduling of messages is done prior to the scheduling of tasks, and the node-centric perspectives are studied. A simple mechanism to dispatch tasks and messages for CAN-based distributed systems is also proposed in this work. This mechanism extends the one that exists in the FTT for the dispatching of messages. The study of the implementation of this mechanism in the nodes gave birth to the specification of a kernel. A goal for this kernel was to achieve a low overhead so that it could be included in nodes with low processing power. In this work a simulator to preview the timeliness of the transmission of messages and of the execution of tasks in a distributed system is presented. The inputs to the simulator are the so-called data streams, which include the producer tasks, the correspondent messages and the tasks that use the transmitted data. Using the worst-case execution time and transmission time, the simulator is able to verify if deadlines are fulfilled in every node of the system and in the network.

There has been increased interest in understanding the significant disparity in U.S. households’ retirement preparedness due to concern about the stability of Social Security benefits, the shift from defined benefit plans to defined contribution plans, and the decreased rate of saving. This dissertation explores a model that can be utilized to understand and enhance retirement preparedness by individuals, educators, practitioners, and policy makers. Retirement preparedness was measured in two different ways—using the income replacement rate and the capital accumulation ratio—for two separate empirical models. The general conceptualization of the framework is based on the retirement planning work of Hershey (2004). This study utilized the 2008 Rand version (Version L) of the Health and Retirement Study (HRS) and 2006, 2008, and 2010 psychosocial and lifestyle questionnaire. The Rand HRS data file is a user-friendly version of the HRS data and contains cleaned data. The two hierarchical regressions were used to analyze the association between retirement preparedness and the theoretical concepts of cultural influence, environmental influence, task components, and psychological influence. Entering the conceptual components as four separate blocks allows for observation of changes in R[2] based on the addition of the conceptual components. This research investigates the following research questions: (a) How strongly are cultural influences associated with retirement preparedness?, (b) How strongly are environmental influences associated with retirement preparedness?, (c) How strongly are task components associated with retirement preparedness?, and (d) How strongly are psychological influences associated with retirement preparedness? Current retirement planning practices are often based on structural profiles such as financial resources, financial needs, and goals. The holistic approach used for this dissertation is based on the awareness of the influence of psychological and personal factors on financial decision making. The results showed that the variables positively associated with the retirement income replacement rate were self-perception of aging, homeownership, stock ownership, household pension ownership, IRA/Keogh ownership, and business ownership. Pre-retirement income log had a highly negative association with the retirement income replacement ratio. Big Five personality and perceived mastery were not significant. However, when asset ownership (excluding homeownership) was not controlled, conscientiousness and low emotional stability became significant and showed a positive association for conscientiousness and a negative association for low emotional stability. Self-perception of aging was a significant psychological variable in both models. The significant variables from the second model measured by the capital accumulation ratio were asset ownerships including homeownership, stock ownership, IRA ownership, real estate ownership, and business ownership. None of the psychological variables were significant, except for agreeableness, which was related negatively to the capital accumulation ratio when the asset ownerships (excluding home ownership) were not controlled. Other significant variables, when asset ownership was not controlled, were home ownership, pre-retirement income log, being non-White.

The purpose of this study is to explore the idea and method of holistic education and if traces of these can be found in four preschool teachers’ statements about their practices in two private preschools located in the state of Tamil Nadu in India. Working holistically is something which UNESCO (Marope & Kaga, 2015) recommends when it comes to early childhood care and education. In a developing country like India primary education is important to growth and development. It is one of the main sustainable development goals and early childhood education is considered a means to reach this goal. This study aims to provide some insight into what a holistic approach to early childhood education can entail. In this study I have explored literature to gain a theoretical knowledge of the idea and working methods of holistic education through a literature review. I then conducted a qualitative interview study where I traced the ideas and methods found in the literature in four preschool teachers’ statements about their practices to gain an understanding of what ideas and methods found in a preschool setting can be considered to lead to holistic outcomes. The results show that the idea and methods of holistic education, as I understand it through the literature review, were evident in the teachers’ statements to various extent, and that that inclusion, balance and connections lead to holistic education. Even though the teachers do not explicitly work with holistic education as Miller (2007, 2010) describes it, this study found that the practices of the teachers, as described by them, promote similar ideas and the same methods could be found. This study can provide a concrete understanding of what a holistic approach to early childhood education can and should involve.

This thesis investigates the concept of dynamic capabilities at both the macro and micro levels, using the study's findings at the micro level to explain phenomena determined at the macro level. In doing so, this provides more of a holistic approach to the discipline. Based on a 'black box' theme, this investigation provides an assimilated macro and micro operationalisation of dynamic capabilities from which it empirically examines such entities at the macro level using a general regression artificial neural network based procedure and at the micro level using an adaptec action research methodology. The findings suggest dynamic capability heterogeneity is as a result of differences in managers' ability to detect and comprehend the significance of incidents, differences in their ability to learn through trial and reflection and the degree of prudence managers demonstrate when implementing resource modification ideas.

The author's interest in this subject emerges from seeing the environment as a whole, consisting of entities which are systems for transformation and which are responsible for the evolution of society. The approach comes from the mutual interaction of man and the environment. This interaction is expressed in many cases by building concepts, rules and theories. Architecture is considered one of the obvious means of this type of interaction by which man, over time, tried to clarify this interaction by building his shelter to accommodate his different life activities. This led to the creation and establishment of rules, constraints, and then theories in architecture that control this interaction. Architecture cannot be seen as a synchronic phenomenon but it is diachronic and in a continous evolution and development. There is a distinction between what one can see in the environment as surface structure and the embedded meaning and symbolism of deep structure. In order to analyse this distinction, the research adopts structuralism as an holistic tool to address this relationship within the environment. For this reason, architectural theories and structuralism are the two pillars to build and test the statement of the study that leads to the provision of an holistic approach to architectural theory based on structuralism. The study takes an empirical approach to test and confirm the holistic approach, hence, it adopts a methodology to analyse and interpret the case study entities. This methodology follows two main approaches to fulfil these objectives: Deductive: A theoretical investigation of the ideas of the interaction between man and the environment which leads to emphasising environmental entities as systems for transformation. This premise leads to the adoption of structuralism as an holistic method and as a tool for the better understanding and analysis of these entities. Inductive: An empirical approach takes Salt city in Jordan as a case study area. This part represents a real field of information and application. The empirical work supports the propositions that architectural phenomena are an embodiment of cultural values and the social structure. The empirical work collected and elicited people's opinions and preferences through an open -ended questionnaire and drawings of cognitive maps. This study helps architects and designers to understand and then analyse the deep structure of the society as a base to design, after taking into consideration the mechanism that connects the surface structure to the underlying cultural values and meanings that are responding to people's needs and requirements. This may be achieved in architecture and urban planning through holistic thinking that is based on structuralism.

The number of studies estimating neighbourhood effects has increased rapidly during the last two decades. Although results from these studies vary, a majority find at least small effects. But to what extent can we trust these estimates? Neighbourhood effect studies face many serious methodological challenges, of which some are related to the fact that people move. The mobility of individuals may cause neighbourhoods to change over time, result in exposure times that are too short and seriously bias estimates. These methodological problems have not been given enough attention in the neighbourhood effect literature: no study controls for them all, and implications of mobility are rarely included in theoretical discussions of neighbourhood effects. In a comprehensive summary and five different papers, I argue that the two scholarly fields of residential mobility and neighbourhood effect studies are intrinsically connected and that any arbitrary separation between the two is both conceptually problematic and risks leading to erroneous conclusions. Studies of neighbourhood effects must address the problems caused by mobility, before it can be convincingly argued that results actually show neighbourhood effects. To do this, longitudinal data are necessary. Furthermore, the connection between the two fields may also have implications for studies of residential mobility.

Municipal wastewater treatment and associated sludge handling is an essential process for modern society and contributes to both human and environmental health. However, it is energy intensive. There has been a focus on cleaning efficiency in the subprocesses, e.g. activated sludge treatment; however, a holistic approach that reviews different system setups in detail is lacking. The aim of this project is to analyze the mass and energy flows through core municipal wastewater treatment plant (WWTP) subprocesses and propose holistic measures to improve the total efficiency. Two configurations for sludge-handling are proposed: incineration and gasification; additionally, detailed models of the mass and energy flows in/out of each subprocess are created. Unit processes such as a heat pump, heat exchangers, and combined heat and power plants are incorporated into each model configuration to maximize the energy efficiency. The result is that the gasification option is self-sufficient in heat and saves over half of the electricity needs. The incineration option is also self-sufficient in heat but still requires significant electricity. Both options contain inspiring characteristics for the future generation of WWTPs.

The aim of this thesis is to support the evaluation of sustainable development strategies for industrial networks in the context of industrial ecology (IE). Industrial networks are a group of units which carry out, or contribute to, industrial activity, and are connected by material and energy flows, but also capital and information exchanges. The components of an industrial network encompass resource extraction, processing and refining, forming and assembly, use, disposal, as well as recycling and reprocessing. The motivation behind this research is the realisation that much of the current environmental system analysis focus within IE lacks a structured approach to considering: • system environment • dynamic nature of the system and its environment • economic and social impacts • the effect of uncertainty on analysis outcomes. It is argued in this thesis that current environmental analysis approaches used in IE can be improved in their capacity to capture the complexity of industrial systems, with the objective of promoting sustainable development. While IE emphasises the benefit of a systems approach to identifying environmental strategies in industry, analysis tools have to date not engaged extensively with important aspects such as the influence of system environment and dynamics on the viability of an environmental strategy, or with the economic or social impacts of industrial system development, which are equally important for sustainable development. Nor is the assessment of the effect of uncertainty on analysis outcomes an integral part of environmental analysis tools in IE. This is particularly significant when, in fact, the degree of uncertainty in assumptions and data used increases with the scope, and therefore the abstraction, of the system under consideration. IE will have to engage with the network and contextual complexities to a greater degree if it is to evolve from a concept to the application of its principles in practice. The main contribution of this thesis is therefore the development of a structured approach to analysing industrial networks for the purpose of identifying strategies to encourage sustainable development, while accounting for the complexity of the underlying system as well as the problem context. This analysis is intended to allow the identification of preferred network development pathways and to test the effectiveness of sustainable development strategies. A top-down, prescriptive approach is adopted for this purpose. This approach is chosen as the industrial network analysis is intended to identify how a network should develop, rather than focusing on how it could develop. Industrial networks are systems which are complex in both their structure and behaviour. This thesis also delivers a characterisation of these networks, which serves two purposes – quantifying key elements of structure and behaviour; and using this information to build a foundation for subsequent industrial network analysis. The value of such an approach can be seen in the following example. With a detailed understanding of individual network characteristics, both separately and collectively, it is possible to determine the source of issues, the means available to address them, any barriers that might exist, and the consequences of implementing any strategic interventions. The analysis approach proposed in this thesis is based on multi-criteria decisions analysis (MCDA), which, as a process, combines initial problem structuring and subsequent quantitative analysis stages. The tools employed within MCDA have been employed variously around considerations of sustainable development. Their value in this thesis is their integration within a rigorous analytical framework. Rigorous problem structuring is attractive as it helps elucidate the complexities of the system and its environment and is, by definition, designed to deal with multiple environmental social and economic criteria that would have to be considered to promote sustainable development. For the quantitative analysis, the industrial network analysis draws from existing analysis tools in IE, but predominately from other systems research disciplines, such as process systems engineering (PSE) and supply chain management (SCM). These fields, due to their maturity and practical focus, have invested a lot of research into system design and strategic planning, capturing system dynamics and uncertainty to ensure, within selected system constraints, that a proposed system or changes to a system are viable, and that the system is capable of achieving the stated objectives. Both PSE and SCM rely heavily on optimisation for system design and planning, and achieve good results with it as an analytical tool. The similarity between industrial networks and process systems / supply chains, suggests that an optimisation platform, specifically multi-objective dynamic optimisation, could be employed fruitfully for the analysis of industrial networks. This is the approach taken in this thesis. It is consistent with the “top down” approach advocated previously, which is deemed preferable for the identification and implementation analysis of strategic interventions. This enables the determination of a structure (design) that is “best” able to operate under future conditions (planning) with respect to the chosen sustainable development objectives. However, an analysis is only ever as good as its underlying data and assumptions. The complexity and scope of the industrial network and the challenge of articulating sustainable development target(s) give rise to significant uncertainties. For this reason a framework is developed within this thesis that integrates uncertainty analysis into the overall approach, to obtain insight into the robustness of the analysis results. Quantifying all the uncertainties in an industrial network model can be a daunting task for a modeller, and a decision-maker can be confused by modelling results. Means are therefore suggested to reduce the set of uncertainties that have to be engaged with, by identifying those which impact critically on model outcomes. However, even if uncertainty cannot be reduced, and the implementation of any strategy retains a degree of risk, the uncertainty analysis has the benefit that it forces an analyst to engage in more detail with the network in question, and to be more critical of the underlying assumptions. The analysis approach is applied to two case studies in this thesis: one deals with waste avoidance in an existing wood-products network in a large urban metropolis; the other with the potential for renewable energy generation in a developing economy. Together, these case studies provide a rich tableau within which to demonstrate the full features of the industrial network analysis. These case studies highlight how the context within which the relevant industrial network functions influences greatly the evolution of the network over time; how uncertainty is managed; and what strategies are preferred in each case in order to enhance the contribution of each network to sustainable development. This thesis makes an intellectual contribution in the following areas: • the characterisation of industrial networks to highlight sources of environmental issues, role the characteristics (could) play in the identification of (preferred) sustainable development strategies, and the need to explicitly consider these in a systems analysis. • the synthesis, adaptation and application of existing tools to fulfil the need for analysis tools in IE that can handle both contextual and system complexity, and address the above mentioned issues of lacking consideration of o system environment o dynamic nature of the system and its environment o economic and social impacts o the effect of uncertainty on analysis outcomes. • the development and demonstration of an industrial network analysis approach that o is flexible enough to model any industrial network at the inter-firm level, regardless of form and configuration of materials and products circulated, and depending on the existing network and the proposed strategies. o is able to encompass a wide range of environmental strategies, either individually or in combination depending on what best suits the situation, rather than focusing on any strategy in particular. o ensures long term viability of strategies, rather than short term solutions delivering incremental improvement. • the development of a comprehensive approach to capturing and assessing the effect of uncertainty on solution robustness for industrial network analysis, including the screening to determine the most important parameters, considering valuation and technical uncertainties, including future uncertainty. The industrial network analysis approach presented in this thesis looks more to how a network should develop (according to a set of sustainable development objectives), rather than how it may in actual fact develop. Consequently, the influence of agent interests and behaviour is not considered explicitly. This may be construed as a limitation of the industrial analysis approach. However, it is argued that the “top down” modelling approach favoured here is useful at a policy-making level. Here, for example, government instrumentalities, trade organisations and industry groupings, non-government organisations and community-based organisations are likely to be interested more in the performance of the network as a whole, rather than (necessarily) following the behaviour of individual agents within the network. Future work could well entertain the prospect of a mixed approach, in which the top-down approach of this thesis is complemented by a “bottom-up”, agent-based analysis. In this manner, it would be possible to give an indication of how attainable the identified industrial network development pathways are. Furthermore, the use of government incentives can be explored to assess if network development could approach the preferred development pathway which is identified using the methodology and results articulated in this thesis.

Problems can be solved using existing knowledge and methods derived from past experiences; and in building design, where buildings are sufficiently similar to those already built, this process can be optimised by creating standardised solutions to common problems. There is significant demand for specialist engineers who can apply these standardised solutions to established problems quickly and accurately; but novel designs generate entirely new problems for which established solutions are not always applicable. Generalist engineers working on novel designs must first define the problems before they can develop options and if necessary, create optimised solutions. Fire safety engineering (FSE) is the process of achieving fire safety in our built environment. The field requires both specialists trained in current practice and generalists skilled in creative and critical thinking. Current fire safety engineering education is mostly aimed at producing specialists, yet there is growing demand for generalists in high-end architecture, hindered by a lack of generalist education. Current education literature in FSE explains in detail what to teach, however they do not explain how to motivate students to learn what is taught; how to create the ‘need to know’ - the purpose that drives learning. The purpose can either be intrinsically motivating (i.e. the subject is interesting) or extrinsically motivating (i.e. if you don’t learn it then you will fail the exam). The former is sustained by autonomy and choice; the latter is sustained by control. Control increases the likelihood that the predicted outcome will be realised, but by definition reduces the likelihood of realising any other outcome, including potential innovation.Initially a study was created to test the effects of creating an autonomous learning environment within a traditional lecture-based ‘fundamentals’ course at the University of Edinburgh. This study, along with observations at a range of US universities led to the formation of an overarching theory of education. Ultimately, purpose is the goal students strive to achieve; autonomy creates the opportunity to think and learn independently; and structure provides the constraints that converge students towards an optimised result, supported by sound evidence and reasoning. Thus the key to generalist education was to provide purpose, autonomy and structure (PAS) in that order. The PAS concept was trialled at EPFL (Switzerland) and the participating students, with no prior knowledge of fire engineering, produced work of exceptional quality. In summary, the present study offers an observational validation that Purpose, Autonomy & Structure (PAS) can be used to effectively support the generalist way of thinking and although the examples given in this paper are related to fire safety engineering (due to the need for generalists in that field), the qualitative evidence on which the conclusions are based is not subject-specific, implying that the PAS methodology could be applied to other disciplines.

This dissertation comprises an exploration of the thesis that a holistic education entailing multi-disciplinary study is essential if classical singers and vocal pedagogues are to be prepared adequately for performance, for their teaching role, and for cooperation in inter-professional relations. The disciplines pertinent to vocal pedagogy are examined, and their varied contributions are discussed with a view to showing the ways in which they are mutually supportive. The case is argued on the basis of an exhaustive analysis of the relevant literature, and is underpinned by my wide professional experience as a soprano, and as a teacher both in primary, secondary and higher education, and in private practice at home and abroad. Starting with a survey of views on vocal pedagogy from biblical and classical times to the present day, important diverse roots are exposed, yielding differing and even conflicting tonal ideals which have a bearing on the consideration of different singing styles, and the interpretation of songs and arias. Ethics and psychology are identified as central to the entire pedagogical process, along with the scientific basis of singing, encompassing acoustics, anatomy and physiology, with special reference to the bearing of the latter two upon vocal health and hygiene. A detailed consideration of singing technique is the centrepiece of the dissertation, building on the scientific basis already presented. The several aspects of technique are discussed, and an understanding of the relations between good technique and scientific awareness is shown to be fundamental to good vocal pedagogical practice. In differing ways all of the disciplines thus far discussed - history, the ethics and psychology, science, vocal technique - contribute to performance, which is the next topic dealt with. In addition, since the evaluation of performance is a question of aesthetics, that branch of philosophy is introduced as a further discipline contributing to the education of the fully equipped singer and vocal pedagogue. While a considerable amount of research has been undertaken by others on the individual disciplines discussed in this dissertation, no study to date has attempted the task of showing the inter-relationships of all of them, and the ways in which together they bear upon classical singing pedagogy. The central theme of the dissertation is that the adoption of a holistic, multidisciplinary approach is of particular benefit to singers and voice teachers, and that such an approach facilitates mutual co-operation between them and other voice professionals.

Online travel shopping has attracted researchers due to its significant growth and there is a growing body of literature in this field. However, research on what drives consumers to purchase travel online has typically been fragmented. In fact, existing studies have largely concentrated on examining consumers’ online travel purchases either grounded on Davis’s Technology Acceptance Model, on the Theory of Reasoned Action and its extension, the Theory of Planned Behaviour or on Roger’s model of perceived innovation attributes, the Innovation Diffusion Theory. A thorough literature review has revealed that there is a lack of studies that integrate all theories to better understand online travel shopping. Therefore, based on relevant literature in tourism and consumer behaviour, this study proposes and tests an integrated model to explore which factors affect intentions to purchase travel online. Furthermore, it proposes a new construct, termed social media involvement, defined as a person’s level of interest or emotional attachment with social media, and examines its relationship with intentions to purchase travel online. To test the 18 hypotheses, a quantitative approach was followed by first collecting data through an online survey. With a sample of 1,532 Worldwide Internet users, Partial Least Squares analysis was than conducted to assess the validity and reliability of the data and empirically test the hypothesized relationships between the constructs. The results indicate that intentions to purchase travel online is mostly determined by attitude towards online shopping, which is influenced by perceived relative advantages of online travel shopping and trust in online travel shopping. In addition, the findings indicate that the second most important predictor of intentions to purchase travel online is compatibility, an attribute from the Innovation Diffusion Theory. Furthermore, even though online shopping is nowadays a common practice, perceived risk continues to negatively affect intentions to purchase travel online. The most surprising finding of this study was that Internet users more involved with social media for travel purposes did not have higher intentions to purchase travel online. The theoretical contributions of this study and the practical implications are discussed and future research directions are detailed.
A compra de viagens online tem atraído investigadores dado o seu significativo crescimento e existe uma crescente literatura nesta área de investigação. Contudo, estudos sobre o que motiva consumidores a comprar online têm sido fragmentados. De facto, os estudos existentes em grande parte baseiam-se no Modelo de Aceitação de Tecnologia de Davis, no Teoria da Ação Refletida, na Teoria do Comportamento Planeado ou na Teoria de Difusão de Inovações de Roger. Uma extensa revisão da literatura permitiu revelar que há uma falta de estudos que integram todas as teorias para a melhor compreensão da compra de viagens online. Deste modo, baseado em literatura relevante na área de Turismo e de comportamento do consumidor, este estudo propõe e testa empiricamente um modelo integrado para explorar quais os fatores que afetam a intenção de comprar viagens online. Mais, propõe um novo constructo, designado de envolvimento com social media, definido como o nível de interesse ou ligação emocional com social media, examinando a sua relação com a intenção de compra de viagens online. Foi utilizada uma abordagem quantitativa para testar as 18 hipóteses, recolhendo dados através de um questionário disponível online. Com uma amostra de 1532 utilizadores mundiais de Internet, o método de Partial Least Squares foi utilizado para verificar a validade e fiabilidade dos dados e testar as relações formuladas entre os constructos. Os resultados indicam que as intenções de comprar viagens online são maioritariamente determinadas pela atitude em relação à compra de viagens online, que por sua vez é influenciada pelas vantagens relativas percebidas e pela confiança na compra de viagens online. Os resultados também revelam que o segundo preditor mais importante das intenções de comprar viagens online é a compatibilidade, um atributo da Teoria de Difusão de Inovações. Por outro lado, apesar de a compra de viagens online ser atualmente uma prática comum, o risco percebido continua a afetar negativamente a intenção de comprar viagens online. Um dos resultados mais surpreendentes deste estudo foi que utilizadores de Internet mais envolvidos com social media relacionados com viagens não tinham maiores intenções de comprar viagens online. As contribuições teóricas deste estudo e as implicações práticas são discutidas e linhas de investigação futura são apontadas.

This thesis uses the case study of the Fallas festival in the city of Valencia (Spain), to assess the value of intangible cultural heritage. Within this framework the thesis explores a number of different issues: for example how social agents frame different qualities and benefits of cultural heritage in order to describe the value and claims for funding the arts. It finds that value assessment for claiming funds presents many challenges such as: identifying the values of the heritage in question; describing them; and ranking them according to their contribution to the public welfare. It examines the methodological techniques for assessing heritage values and goes on to discuss a number of tools that are, or could be, used for assessment. The thesis also explores how public bodies legitimise cultural funding. It examines the role of non-government arts organisations in supporting the arts. It proposes the analysis of donor decisions through a multi-attribute technique where donors state their importance to donor situations under specific conditions or attributes. Finally, it describes how the stakeholder approach can be applied for searching new ways of funding festivals. It also considers how intangible cultural heritage goods can be assessed within the process of cost-benefit evaluation. It also analyses how public bodies, as the principal supporters of culture, deal with the problem of valuing intangibles on social investments. The study uses the Fallas festival to test the research hypothesis. It uses a number of economic and statistical techniques to evaluate the Fallas Festival, these include Contingent Valuation, Choice Experiment and Descriptive and Multiatribute Statistics. The statistical techniques reveal that historical benefits are intrinsically valuable in the Fallas festival. The historical value that the members of the neighbourhood associations place on the Fallas festival justify that local social agents should support this festival.

"Combat Dance" is an eclectic blend of combat and dance art forms combined and taught from the Fall 2001 to Spring 2003. As defined here, combat dance is a blend of techniques and principles gleaned from both unarmed and armed aspects of stage combat, martial arts (such as aikido and kung fu), modern dance and other expressive movements used to tell a story of conflict. Its primary purpose is to provide both actors and non-actors greater awareness and control of their bodies and to provide a range of creative avenues of expression. Combat dance gives the performers a unique and holistic set of exercises and skills that leave no part of the body, mind, or - even deeper - the spirit uninfluenced. The thesis begins with the vision and birth of the class, a description of the preparatory research, an analysis of the reasons for the class, and reflection, revelations, and realizations gained through teaching the class. The ultimate focus of this thesis is to aid anyone interested in any type of combat or dance-related movements: dancers, non-dancers, actors, non-actors, movement coaches, and even those in the fields of dance or drama therapy.

The desire to develop a holistic framework for knowing and modelling in human enterprises is not new. Methodologies, such as Systems Dynamics, Soft Systems and the Viable Systems Model all claim a holistic perspective. Each of these approaches emphasises the interrelatedness of `things', rather than the `things' themselves. Thus, they avoid the possible fragmentation that can occur when elements within a situation are treated as if they exist independently. Unfortunately, the systems approaches flounder because they fail to reconcile knowledge with the path that brings it into being, or to satisfactorily deal with the concepts of order or communication in language. The Thesis, therefore, provides a greater clarification of these issues, in the light of enactive cognitive science, chaos theory and contemporary theories on dialogue. As a result, a new framework is presented, for knowing and modelling in human enterprises, that is based on our `new' understanding of holism. The organisational context of the Thesis is provided by two generic models, both developed by the author (a model of Duopoly Competition and a model of Chaos Control ), together with a case study of the Danish hearing aid manufacturer Oticon. The Thesis concludes by presenting various insights arising from our new frame of reference and reflecting on their challenges for organisations.

Automatic image annotation is the process of assigning keywords to digital images depending on the content information. In one sense, it is a mapping from the visual content information to the semantic context information. In this thesis, we propose a novel approach for automatic image annotation problem, where the annotation is formulated as a multivariate mapping from a set of independent descriptor spaces, representing a whole image, to a set of words, representing class labels. For this purpose, a hierarchical annotation architecture, named as HANOLISTIC (Hierarchical Image Annotation System Using Holistic Approach), is dened with two layers. At the rst layer, called level-0 annotator, each annotator is fed by a set of distinct descriptor, extracted from the whole image. This enables us to represent the image at each annotator by a dierent visual property of a descriptor. Since, we use the whole image, the problematic segmentation process is avoided. Training of each annotator is accomplished by a supervised learning paradigm, where each word is represented by a class label. Note that, this approach is slightly dierent then the classical training approaches, where each data has a unique label. In the proposed system, since each image has one or more annotating words, we assume that an image belongs to more than one class. The output of the level-0 annotators indicate the membership values of the words in the vocabulary, to belong an image. These membership values from each annotator is, then, aggregated at the second layer by using various rules, to obtain meta-layer annotator. The rules, employed in this study, involves summation and/or weighted summation of the output of layer-0 annotators. Finally, a set of words from the vocabulary is selected based on the ranking of the output of meta-layer. The hierarchical annotation system proposed in this thesis outperforms state of the art annotation systems based on segmental and holistic approaches. The proposed system is examined in-depth and compared to the other systems in the literature by means of using several performance criteria.

För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras. Produktionsteknisk mätteknik och resultat från utförda mätningar används sedan som indata för statistisk processtyrning och övervakning av produktionsprocesser. Syftet med vår forskning har varit att först ta fram en nulägesbild av mätteknisk beredning inom fordons- och flygindustrin och utifrån den identifiera framtida trender med behovsanalys och gap. Utifrån analysen har vi sedan utforskat och utvecklat en modell och metodik för mätteknisk mät- och styrbarhetsberedning. I denna licentiat avhandling har vi utforskat området geometrisk och dimensionell mät- och styrbarhetsberedning (GMCP - Geometrical and dimensional Measurement and Controllability Planning). Vi presenterar en nulägesanalys av området och vi presenterar en teori med modell och ramverk för GMCP. Vidare har vi utforskat en metodik och verktyg benämnd kvalitetssäkringsmatris (QAM - Quality Assurance Matrix) och som vi lyfter fram i denna avhandling. I slutet av avhandlingen presenteras och diskuteras dem hittills uppnådda resultaten från forskningen och i det sista kapitlet dras slutsatser och den fortsatta forskningen inom ”SIMET-GICP” projektet presenteras.
In order to ensure final product quality on machined components, manufacturing enterprises must measure and inspect the geometrical and dimensional characteristics of components before they go into higher-value assemblies. Commonly, the geometrical and dimensional measurement and inspection occurs every time at machine tool set-up, when a line is restarted or if the production process is changed. Production metrology and results from production measurements is used as input data for statistical process control and monitoring of production processes. The purpose of our research has been to firstly perform a state of the art analysis in the area of measurement planning applied in the automotive and aerospace industry. The output from the state of the art study has then been used to identify future trends and needs including a gap analysis. Then we used the analysis to explore and develop a model and methodology for measurement and controllability planning.   In this licentiate thesis we have explored the area of GMCP (Geometrical and dimensional Measurement and Controllability Planning). As a major result in this thesis a state of the art survey on GMCP is presented. Based on the state of the art study a theory and model framework for GMCP has been explored and a methodology and tool called QAM (Quality Assurance Matrix) is highlighted in this thesis. In the end of the thesis we present and discuss the present research results we have accomplished and in the final chapter we draw conclusions and outline the continued research within the SIMET-GICP project.

In a time when the amount of biological data present in the public domain is becoming increasingly vast, the need for good classification systems has never been greater. In the field of glycoscience the necessity of a good classification for the enzymes involved in the biosynthesis, modification and degradation of polysaccharides is even more pronounced than in other fields. This is due to the complexity of the substrates, the polysaccharides, as the theoretical number of possible hexa-oligosaccharides from only hexoses exceeds 10¹² isomers! 

An initiative to classify enzymes acting on carbohydrates began around 1990 by the French scientist Bernard Henrissat. The resulting database, the Carbohydrate Active enzymes database (CAZy), classifies enzymes by sequence similarity into families allowing the inference of structure and catalytic mechanism. What CAZy does not provide however, are means to understand how members of a family are related, and in what way they differ from each other. The top-down approach used in this thesis, combining phylogenetic analysis of whole CAZy families, or sub-families, with structural determinations and detailed kinetic analysis allows for exactly that.  

Finding determinants for transglycosylation versus hydrolysis within the xth gene product family of GH16 as well as restricting the hydrolytic enzymes to a well defined clade are integral parts of paper I. In paper II a new bacterial sub-clade within CE8 was discovered. The structural determination of theEscherichia coli outer membrane lipoprotein YbhC from from the new sub-clade explained the difference in specificity. The information provided in the two papers of this thesis gives a better understanding of the development of different specificities of diverse CAZY families as well as it aids in future gene product annotations. Furthermore this work has begun to fill the white spots uncovered in the phylogenetic trees.

 

 

Most populous school districts operate using a bureaucratic hierarchical organizational structure developed primarily for industry, a system structure that has remained intact for a century despite evolving from a manufacturing to a knowledge-based economy. Although strong for efficiency, this system structure is resistant to change and promotes worker isolation, not ideal for a collective educational approach desired in the 21st century. The purpose of this quantitative correlational study was to investigate the relationship among a bureaucratic hierarchical school system structure, principal leadership, and school culture to determine if and how the three variables relate through the collective lens provided by the integral leadership theory (Küpers & Weibler, 2008) and the Full-Range Leadership Theory, or FRLT (Bass & Avolio, 2004). Thirty principals from three urban districts in North Carolina responded to items on the Multifactor Leadership Questionnaire, Form 5X (MLQ Form 5X) and the School Culture Survey (SCS) and four demographic questions. The study’s results revealed that the administrators appear to combine aspects of both transformational and transactional leadership in the urban schools. Each of the six culture factors on the SCS was significant with transformational leadership, and three of the six culture factors, learning partnership, collaborative leadership, and teacher collaboration, were also significant with transactional leadership. A holistic analysis shows that the principals are demonstrating effective leadership with corresponding positive school cultures despite the constraints a bureaucratic hierarchical school district structure presents. The results suggest that the principals are successfully integrating structural context, cultural elements, and leadership in an organizational form not necessarily designed to promote teamwork and collaboration essential for educational success.

Coral reefs are in a worldwide state of crisis due to overexploitation. One of the factors contributing to the over exploitation is the marine ornamental industry. This industry utilises a diversity of organisms, comprising approximately 1470 species of fish and more than 300 species of invertebrates. Between April and December 2007, five of the 18 companies who had import permits for South Africa, imported a total of 359 different ornamental species, 252 of these were fish species while the remaining 107 species were invertebrates. During these nine months a total of 32 005 individual organisms were imported into South Africa by the five companies. There were two groups of fish that represented the highest import volumes. These were Amphiprion spp. and Pomacentradae spp., as well as the Gobidae spp. These groups represented 38% and 19% respectively of the total number of fish imported" Aquaculture has the potential to substantially reduce the harvesting pressure on coral reef organisms globally. A small-scale multi-species mariculture system was designed and constructed for benthic egg-laying species of fish (brood stock), corals, and ornamental algae. The system was designed to be low cost and easy to operate. The total capital costs for the system was R15 680.70. In order to estimate the potential yield of an aquaculture facility it is important to know the growth rate of the proposed species under pilot conditions. The use of artificial lighting regimes in aquaculture comes at a financial cost. It is for this reason that it is important to know what lighting scenario yields the highest growth rate of corals. The effects of photoperiod were tested on Sinularia sp. of coral. Two photoperiods were tested, namely: Groups (8:16 h Iight:dark cycle) and Group12 (12:12 h light:dark cycle). No significant difference in weight was found between Group8 and Group12 (p = 0.975). There was however a significant increase (p = 0.002) in Surface-area Pixel Value (SPV) for Groups (1996.73 millipixels pixel-1 day -1) compared to Group12 (983.73 millipixels pixel-1 day -1). The use of a 8:16 h lightdark cycle can thus yield coral of a larger size but not necessarily a higher mass.

Component-Based Development (CBD) has been broadly used in software development as it enhances the productivity and reduces the costs and risks involved in systems development. It has become a well-understood and widely used technology for developing not only large enterprise applications, but also a whole spectrum of software applications, as it offers fast and flexible development. However, driven by the continuous expansions of software applications, the increase in component varieties and sizes and the evolution from local to global component repositories, the so-called component mismatch problem has become an even more severe hurdle for component specification and retrieval. This problem not only prevents CBD from reaching its full potential, but also hinders the acceptance of many existing component repository. To overcome the above problem, existing approaches engaged a variety of technologies to support better component specification and retrieval. The existing approaches range from the early syntax-based (traditional) approaches to the recent semantic-based approaches. Although the different technologies are proposed to achieve accurate description of the component specification and/or user query in their specification and retrieval, the existing semantic-based approaches still fail to achieve the following goals which are desired for present component reuse: precise, automated, semantic-based and domain capable. This thesis proposes an approach, namely MVICS-based approach, aimed at achieving holistic, semantic-based and adaptation-aware component specification and retrieval. As the foundation, a Multiple-Viewed and Interrelated Component Specification ontology model (MVICS) is first developed for component specification and repository building. The MVICS model provides an ontology-based architecture to specify components from a range of perspectives; it integrates the knowledge of Component-Based Software Engineering (CBSE), and supports ontology evolution to reflect the continuous developments in CBD and components. A formal definition of the MVICS model is presented, which ensures the rigorousness of the model and supports the high level of automation of the retrieval. Furthermore, the MVICS model has a smooth mechanism to integrate with domain related software system ontology. Such integration enhances the function and application scope of the MVICS model by bringing more domain semantics into component specification and retrieval. Another improved feature of the proposed approach is that the effect of possible component adaptation is extended to the related components. Finally a comprehensive profile of the result components shows the search results to the user from a summary to satisfied and unsatisfied discrepancy details. The above features of the approach are well integrated, which enables a holistic view in semantic-based component specification and retrieval. A prototype tool was developed to exert the power of the MVICS model in expressing semantics and process automation in component specification and retrieval. The tool implements the complete process of component search. Three case studies have been undertaken to illustrate and evaluate the usability and correctness of the approach, in terms of supporting accurate component specification and retrieval, seamless linkage with a domain ontology, adaptive component suggestion and comprehensive result component profile. A conclusion is drawn based on an analysis of the feedback from the case studies, which shows that the proposed approach can be deployed in real life industrial development. The benefits of MVICS include not only the improvement of the component search precision and recall, reducing the development time and the repository maintenance effort, but also the decrease of human intervention on CBD.

ABSTRACT When we look at artists in contemporary society it is unfortunate how many of them turn to drugs, alcohol, and suicide as a means to cope with and escape the world. Sadly, there are artists who never live long enough to have a career or share their brilliance with the world. This tragedy is the underlying motivation for this project. One of our goals at the school where I teach, Idyllwild Arts Academy, is to help prepare students for a life in the arts. For the most part we focus on the skills and concepts of their discipline. This focus inherently tends to eliminate or overlook some major concepts related to the physical, mental, and spiritual growth of the students. The purpose of this study was to discover the major concepts of health and longevity and address the best practices for creating an advanced curriculum that addressed these concepts in relation to the context of the students and school where I teach. The guiding questions for this project, in relation to the students at Idyllwild Arts Academy, were: What are the major ideas and concepts that support and promote positive personal growth for students at Idyllwild Arts Academy? What exercises will contribute to each student’s health and longevity. What skills are necessary for coping with the challenges and demands of being an artist in contemporary society? What will help each student achieve his or her full potential in life? To achieve the purpose of this study, I followed these steps: I reviewed literature about health and longevity that related to the context of my school and students, based on the findings of the literature review and my experience I created a draft of the curriculum, next I identified a group of experts and asked them to review the curriculum and complete a survey, once all the survey’s were returned I organized the data and looked for patterns, finally I compiled a list of recommendations based on the data to use when the curriculum is implemented. In addition to the list of recommendations, I have identified three major limitations that need to be addressed when implementing the curriculum. Please note, the curriculum will not be implemented as part of this project.

In recent years, the city has become a primary setting for a diversity of tourist activities. However, the nature of the urban experience, from the perspective of tourist-city interactions, has not been examined in detail. In this particular arena, the concepts of place image and the tourist experience are very relevant, as processes of tourist image formation and modification are linked to the formation of tourists' expectations. In tum, expectations can have the potential to influence tourist choices and spatial behaviour patterns, in the event of an actual visit. Certainly, probability of patronage of a tourist attraction would appear to relate directly to how well that location fits into the simplified 'cognitive map' held by the individual. Overall, knowledge of how individual and groups of tourists interact and acquire information about the urban environment has also been under researched. The thesis therefore examines the main interrelationships between tourists' place images, expectations and spatial behaviour. It introduces an approach for examining such relationships from a more holistic, interdisciplinary perspective than has been employed in previous tourism image and behaviour research. Notably, a longitudinal dimension is introduced for the study of image modification, using an innovative, multi-stage approach. By elaborating, critiquing and applying some of the key concepts in tourist imagery and spatial behaviour in the context of tourist-historic cities, the thesis identifies a connection between tourists' images and spatial behaviour. The UK historic cities of Exeter and Bath were used as case studies for the empirical application of the multi-method framework, and primary data were collected via questionnaires, an experimental panel of visitors and semi-structured interviews. As well as contributing new themes to current theoretical and conceptual debates, the empirical findings identify a clear niche for image-behaviour relationships as a highly relevant concept for tourism studies. In particular, tourists' spatial behaviour is shown to influence the content of tourists' urban images, and in tum, tourists' images of the city can predispose them to certain activity choices. Conclusions are also drawn regarding the influences of different 'image formation agents' and direct tourist experience of a city as a strong agent of image modification.

A iluminação pública alterou profundamente a nossa percepção e uso do espaço urbano nocturno. Compreendida muitas vezes apenas como uma questão técnica em vez de humana, é baseada principalmente no desempenho fotométrico da visão, deixando de fora outras dimensões humanas, como a psicologia da percepção. Actualmente, a iluminação pública está particularmente direccionada para a redução do consumo energético através do uso de novas tecnologias, tal como iluminação adaptativa e fontes de luz LED e o uso de soluções de iluminação standardizados. Neste contexto surge a oportunidade para o desenvolvimento de novas abordagens à iluminação que tirem partido da flexibilidade inerente destes sistemas, melhorando a relação entre o bem-estar do utilizador e o consumo de energia, contribuindo assim para uma prática de design mais sustentável. Com base numa abordagem research through design, foi utilizada uma metodologia mista, de natureza não intervencionista e intervencionista. A partir de uma inicial revisão bibliográfica e da experiência profissional do investigador, considerou-se que adaptabilidade é um importante factor técnico e de design para a melhoria da iluminação pública. Propondo o desenvolvimento de um método orientado para o utilizador, que determine os cenários de iluminação adaptativa para a condição mais adequado e mínima aceitável, considerando uma relação utilizador-espaço específica, com base na percepção de bem-estar do utilizador e a avaliação da qualidade dos cenários configurados. Para apoiar a implementação do método foi desenvolvido um quadro de referência - Continuidade de Luminância Percepcionada como forma de descrever o comportamento da iluminação adaptativa. A informação reunida - objectiva e subjectiva - fornece uma base empírica para que profissionais da iluminação possam criar soluções personalizadas para um contexto físico e humano. Foi formulada a hipótese de investigação que o método proposto, potencia a criação de soluções de iluminação mais ajustadas e flexíveis. Permitindo a adequação de normas suportada em dados objectivos para uma relação utilizador-espaço específica. Dando uma resposta efectiva ao nível do bem-estar do utilizador e da gestão energética, promovendo uma prática de design mais sustentável e melhorando a experiência nocturna. Para testar a hipótese foi executada uma experiência em espaço real como um primeiro caso de estudo na vila de Arraiolos, Portugal. Uma segunda experiência foi realizada com o objectivo de testar a consistência dos dados prévios e confirmar a hipótese primária. Após a análise e validação estatística dos dados recolhidos, foi possível afirmar que a tendência de escolha em ambas as experiências foi muito semelhante, significando que os cenários de iluminação inicialmente considerados como adequados eram reais e significativs, proporcinando elevado nível de apreciação da qualidade da luz. Significa igualmente que existe uma relação entre a configuração da iluminação, distância de visibilidade e a ilusão perceptiva de que um espaço está totalmente iluminado. Mostrou-se ainda que a maioria dos participantes aceitaria iluminação pública adaptativa como prática comum dentro do quadro de referência da Continuidade de Luminância Percepcionada. Com base nos resultados, concluiu-se que o método proposto é uma ferramenta de design válida na concepção de soluções de iluminação pública adaptáveis, confirmando a hipótese primária e secundárias, demonstrando a sua relevância para uma prática de design de iluminação mais sustentável e a melhoria da sustentabilidade do espaço urbano nocturno.
ABSTRACT: Public lighting altered profoundly the way we perceive and use nighttime urban space. It often is understood only as a technical issue rather than a human one, mostly based on photometric visual performance, leaving mostly out other human dimensions such as the psychological perception of light. Currently, public lighting is predominately directed to reducing energy consumption by means of the use of new technologies, such as adaptive lighting and LED light sources and the use of standardized lighting schemes. In this context, there is an opportunity to develop new lighting approaches that take advantage of the inherent flexibility of these systems to improve the relationship between user's well-being and energy management, contributing to a more sustainable design practice. Based on a research-through-design approach, a mixed methodology was used with a non-interventionist and interventionist nature. From literature review and professional experience, we considered that adaptability was an important technological and design factor to improve public lighting. Proposing the development of a user-oriented method that determines adaptive lighting scenarios for the most adequate and minimum acceptable lighting condition, for a specific user-space relationship, based on the user’s perception of well-being and the assessment of the perceived lighting quality of the scenarios. To support the implementation of the method, the Perceived Luminance Continuity framework was developed as a way to describe the adaptive lighting behaviour pattern. The gathered data - objective and subjective - provide an empirical basis for lighting professionals to design customized solutions. We hypothesized that the proposed method, would allow the design of more tailored and flexible lighting solutions. Allowing the adjustment of standards based on objective data for a specific user-space relationship. Promoting a more sustainable design practice that give an effective response to the user’s well-being and energy management, improving the nighttime experience. To test the hypothesis, an outdoor field experiment was conducted as a first case study, in the Village of Arraiolos, Portugal. A second experiment was carried out, aiming to test the consistency of the previous data and confirmation of the primary hypothesis. After analysis and statistical validation of the collected data, we can say that the tendency of choices in both experiments was very similar, meaning that the initial lighting scenarios considered as adequate were real and meaningful, with a high appraisal of lighting quality. It also showed that there was a relationship between the lighting configuration, visibility distance and the perceptual illusion of a fully lit space. Moreover, it shows that the majority of participants would accept adaptive public lighting, as common practice within the Perceived Luminance Continuity framework. Based on the results, we concluded that the proposed method is a valid tool for the design of adaptive public lighting solutions. Confirming the primary and secondary hypothesis, showing its relevance in the development of a more sustainable lighting design practice and improving the sustainability of the urban nighttime space.

Rural renewable electrification programs are increasingly being used as a means of providing the rural poor in developing countries with access to electricity. Those programs have varied significantly in design and implementation, as well as in their degrees of success. The explanations for the lack of success and the non-sustainability of the earliest programs are widely accepted as these tended to be technical demonstration projects that relied totally on funding from donor organisations or governments. These projects ignored or overlooked the vital question of how ongoing operational, maintenance and replacement costs would be met. Many genuine programs, however, also met with limited success and much effort has been invested in attempting to understand the reasons for this lack of success. To increase the rates of success of these programs, best practice guidelines were developed. Despite these efforts, many programs have continued to meet with limited success. These points required better explanations of the reasons for program success and failure, which requires a greater understanding of these programs. This thesis looks more closely at solar PV electrification programs being undertaken in the Asia-Pacific region to understand why some programs continue to be more successful than others. It aims to understand the decisions behind the planning and implementation of the programs and the reasons that are being implemented in the way that they are, the selection of program objectives, the actual benefits of the programs the and causes of any factors that contribute to their apparent success or lack of success. This understanding is obtained by undertaking in-depth comprehensive field surveys to obtain the views of all program stakeholders. The outcomes of these field surveys are then used to develop a comprehensive set of success criteria and a set of indicators that can be used to measure the success of rural renewable electrification programs. A roadmap that could be followed by the program planners and implementers to ensure program success is also provided.

This work addresses the problem of finding an improved solution to Computer Integrated Manufacturing (ClM) Architecture and Systems Design. The current approaches are shown to be difficult to understand and use, over complex. In spite of their complexity of approach they lack comprehensiveness and omit many factors and dimensions considered essential for success in today's competitive and often global market place. A new approach to ClM Architecture and Systems Design is presented which offers a simpler, more flexible and more robust format for defining a particular ClM System within a general architectural framework. At the same time this new approach is designed to offer a comprehensive and holistic solution. The research work involved the investigation of current approaches and research and development initiatives focusing particularly on the CIM-OSA and GRAI Integrated methodologies in the field of ClM Architecture. The strengths and weaknesses of the various approaches are examined. Developments in other related fields including manufacturing systems, manufacturing management, information technology and systems generally have been investigated regarding their relevance and possible contribution to an improved solution. The author has built on his practical experience in creating, designing and managing the implementation of a global CIM system. The authors work on several publicly funded collaborative research and development projects relevant to the problem area is described. These include CIM-OSA, IMOCIM and TIQS projects. In the latter two projects the author was instrumental in developing the methodological approach based on a systems approach to business processes in connection with the design of quality and manufacturing systems. Both of these projects have contributed to this work. The author has also participated in the global IMS programme as a rapporteur for the European Commission and this helped to provide a global perspective on the problems of manufacturing companies as they attempt to compete in a world wide market place. The results of this work provide the basis for a radically improved approach to ClM Architecture and Systems Design based on the holistic view of an enterprise. The approach developed supports the business process view of an enterprise; addresses the people and organisational aspects; leads to ClM solutions focused on meeting enterprise goals; and is able to deal with a significantly increased scope and complexity compared with existing methods yet is easily understood and more simple to simple to apply than current approaches.
