Pinka, Petr. "Ocenění společnosti Kordárna, a.s." Master's thesis, Vysoká škola ekonomická v Praze, 2010. http://www.nusl.cz/ntk/nusl-74984.
Full textAbstract:
This diploma thesis is tasked to evaluate the company Kordárna Inc. with the view of its sale within the frame of reorganization as a nonliquidating solution to its insolvency. The evaluation of the company Kordárna Inc. is performed to the date of January 1st, 2009. By then the company, due to many unfavorable conditions, falls into existential problems that have to be immediately solved. The reorganization plan is allowed and processed within the framework of higher creditors' satisfaction. An integral part of this plan is also the desirable evaluation of the company Kordárna Inc. with the view of its sale to a new investor. Within these issues, both the detailed external and internal analysis of the company and the financial analysis of the 5 preceding fiscal periods are processed (years 2004-2008). Consequently, based on many assumptions, the financial plan for the 4 following fiscal periods (2009-2012) is conducted, and the evaluation of the company Kordárna using 4 evaluation methods -- FCFF, FCFE, EVA and Liquidation value methods -- is processed.

Shreve, Matthew Adam. "Automatic Macro- and Micro-Facial Expression Spotting and Applications." Scholar Commons, 2013. http://scholarcommons.usf.edu/etd/4770.
Full textAbstract:
Automatically determining the temporal characteristics of facial expressions has extensive application domains such as human-machine interfaces for emotion recognition, face identification, as well as medical analysis. However, many papers in the literature have not addressed the step of determining when such expressions occur. This dissertation is focused on the problem of automatically segmenting macro- and micro-expressions frames (or retrieving the expression intervals) in video sequences, without the need for training a model on a specific subset of such expressions. The proposed method exploits the non-rigid facial motion that occurs during facial expressions by modeling the strain observed during the elastic deformation of facial skin tissue. The method is capable of spotting both macro expressions which are typically associated with emotions such as happiness, sadness, anger, disgust, and surprise, and rapid micro- expressions which are typically, but not always, associated with semi-suppressed macro-expressions. Additionally, we have used this method to automatically retrieve strain maps generated from peak expressions for human identification. This dissertation also contributes a novel 3-D surface strain estimation algorithm using commodity 3-D sensors aligned with an HD camera. We demonstrate the feasibility of the method, as well as the improvements gained when using 3-D, by providing empirical and quantitative comparisons between 2-D and 3-D strain estimations.

Full textAbstract:
The use of nonlinear signal analysis measures to characterize electroencephalographic (EEG) recordings can be key for a better understanding of the underlying brain dynamics. In neurological disorders such as epilepsy, these dynamics are altered as result of a disturbed coordination between neuronal populations. The aim of this thesis is to characterize the seizure-free interval of EEG recordings from epilepsy patients by means of nonlinear signal analysis techniques to investigate whether this type of analysis can contribute to the localization of the seizure onset zone, the brain region from which initial seizure discharges can be recorded. For this purpose, we used a
surrogate-corrected nonlinear predictability score and a surrogatecorrected nonlinear interdependence measure to analyze all-night EEG recordings from epilepsy patients implanted with hybrid depth electrodes equipped with macro contacts and micro wires. Our results show that the combined analysis of macro and micro EEG recordings may help to further increase the degree to which quantitative EEG analysis can contribute to the diagnostics in epilepsy
patients.El uso de medidas de análisis no lineales de señales para caracterizar registros electroencefalográficos (EEG) puede ser clave para una mejor comprensión de las dinámicas cerebrales subyacentes.

El objetivo de esta tesis es caracterizarel intervalo de registros de EEG libre de crisis epilépticas de pacientes con epilepsia mediante técnicas de análisis no lineales de señales para investigar si este tipo de análisis puede contribuir ala localización del SOZ (en inglés, Seizure onset zone), la región del cerebro donde se pueden registrar las descargas iniciales de las crisis epilépticas. Con este propósito, utilizamos una puntuación de predictibilidad no lineal corregida por sustitutos y una medida de interdependencia no lineal corregida por sustitutos para analizar registros EEG de pacientes con epilepsia grabados durante noches completas implantados con electrodos híbridos equipados con macro- y microcontactos. Nuestros resultados demuestran que el análisis combinado de macro- y micro-registros de EEG puede ayudar a aumentar el grado en el que el análisis cuantitativo de EEG puede contribuir al diagnóstico de pacientes con epilepsia.

Humans and machines interact with each other on a variety of scales. Interactions can involve tightly coupled interfaces or even be socio-technical in nature. In terms of large complex systems, humans learn to interact and access these systems in the context of dierent social, political, technical, and economic environments. And yet despite this breadth, research on human-machine interactions on all scales depends on having metrics for evaluation and platforms upon which measurement can take place. This thesis investigated the utilization of new metrics for studying human-machine interfaces and systems at a micro and macro scale. At the micro scale, we investigated how humans may strategize to move their bodies in order to complete a agility-based running tasks. For a slalom course, an optimal control model was formulated to analyze the characteristics of an optimal path trajectory to complete the task as quickly as possible.
Opportunities to improve the model were informed by the utilization of a \micro" system - wearable inertial measurement unit (IMU) devices. While the path trajectories estimated from these devices have limitations, IMUs offer an opportunities to measure human movement in natural operational environments. In the context of space exploration, such natural environments could also include planetary surfaces with reduced gravity. To evaluate how locomotion might change in such conditions, the optimal control model was used to investigate how an optimal path trajectory would change while completing the slalom task in reduced gravity. The results demonstrated that as gravity decreased, it would take a human more time to complete the task and the curvature about turning regions would decrease (wider turns).
The results and limitations of the model in nominal and reduced gravity conditions demonstrated the strong influences gravity and ground reaction forces have on the path trajectories humans can execute. Investigating some of the limitations of the optimal models depended on having experimental trajectories estimated from the IMUs as a platform of measurement. Reflecting on how the curvature of the path trajectories decreased as gravity decreased, the metric of integrated curvature was proposed for analyzing the path trajectories of humans completing an agility task. The feasibility of using this metric was analyzed via a pilot study of another agility-based running task. Along with other common metrics of characterizing agility and path trajectories (task completion time and path length), the integrated curvature metric was evaluated using both optical motion capture (Vicon) and wearable IMU measurement platforms.
The pilot study results demonstrated that subject performance in terms of completion time, path length, and integrated curvature could depend on the structure of the task and whether a subject had a priori knowledge of the task goal. Furthermore, the results demonstrate that there are opportunities to leverage the integrated curvature metric via the wearable IMU measurement platform to make decision-making conclusions. Wearable IMUs offer a measurement platform that could be utilized in natural field settings, including reduced gravity planetary environments. But in order to test out and improve metrics for IMUs in these conditions, we require access to reduced gravity research platforms. Accessibility to microgravity platforms is complex and dependent on a variety of factors beyond just financial costs.
And just as it is important to use human performance measurement platforms and metrics that can be leveraged in dierent operational environments for generalized user populations, it also important that access to microgravity research platforms is available for non-traditional partners. Non-traditional partners include users like startups, early career academics, emerging space nations, and education outreach groups. In order to capture the complexities and nuances behind accessibility for end users in the microgravity research ecosystem, new metrics of economic openness and administrative openness were proposed. The current and future microgravity research ecosystems were surveyed using case study research methods. Systems architecture methods were utilized to analyze the stakeholders and forms of access (pathways) present in the ecosystem.
Analysis demonstrated that mixed public/private pathways can foster relatively high economic and administrative openness, but these levels of openness can decrease dependent on the capabilities and type of the end user and the type of funding sources used at dierent stages of the pathway. Opportunities exist to refine the accessibility metrics and add new dimensions of analysis. Whether it be for wearable devices or microgravity research, by refining metrics and examining platforms now, we can help ensure accessibility to these systems for any type of user in the future.

Full textAbstract:
The need for high speed and cost efficient inspection in manufacturing lineshas led to a vast usage of camera-based vision systems. The performance ofthese systems is sufficient to determine shape and size, but hardly to an accuracylevel comparable with traditional metrology tools. To achieve highprecision shape/position/defect measurements, the camera techniques haveto be combined with high performance image metrology techniques whichare developed and adapted to the manufactured components. The focus ofthis thesis is the application of enhanced image analysis as a tool for highprecision metrology. Dedicated algorithms have been developed, tested andevaluated in three practical cases ranging from micro manufacturing at submicronprecision to meter sized aerospace components with precision requirementsin the 10 μm range.The latter measurement challenge was solved by low cost standard consumerproducts, i.e. digital cameras in a stereo configuration and structured lightfrom a gobo-projector. Combined with high-precision image analysis and anew approach in camera calibration and 3D reconstruction for precise 3Dshape measurement of meter sized surfaces, the achievement was fulfilledand verified by two conventional measurement systems; a high precisioncoordinate measurement machine and a laser scanner.The sub-micron challenge was the implementation of image metrology forverification of micro manufacturing installations within a joint Europeaninfrastructure network, EUMINAfab. The results were an unpleasant surprisefor some of the participating laboratories, but became a big step forwardto improve the dimensional accuracy of the investigated laser micromachining, micro milling and micro-printing systems, since the accuracy ofthese techniques are very difficult to assess.The third high precision metrology challenge was the measurement of longrange,low-amplitude topographic structures on specular (shiny) aerodynamicsurfaces. In this case Fringe Reflection Technique (FRT) was appliedand image analysis algorithms were used to evaluate the fringe deformationas a measure of the surface slopes to obtain high resolution data. The resultwas compared with an interferometric analysis showing height deviation inthe range of tens of micrometers over a lateral extension of several cm.QC 20170523

Full textAbstract:
Understanding organizational behavior (OB) has profoundly influenced organizational performance and how people behave in organizations. Researchers have suggested various micro and macro organizational behaviors to be the impetus for high-performing organizations. Through a policy capturing approach this study builds on these findings by specifically examining the perceptions of micro and macro organizational behaviors in an organizational setting. The participants (n =181) completed a Micro and Macro Organizational Behavior Perceptions Questionnaire. Results showed perception differences exist between subordinates and supervisors. Additionally, participants perceived job satisfaction to be the most important micro organizational behavior, whereas organizational design was perceived to be the most important macro organizational behavior. However when comparing hierarchal positions in the organization, supervisors weighted leadership as the most important and subordinates weighted job satisfaction as the most important organizational behavior. While these findings only scratch the surface as to how organizational behavior is perceived, the implications challenge leaders to close the OB perception gap. Correspondingly, organizational behavior thinking may result in improving individual and organizational performance.

Full textAbstract:
This project concentrated upon the development of the Standardization Transport Model (STM) by assembling the largest possible assessment platform. It combines data from all of the major Well-to-Wheel (WtW) models in the field. The STM was developed for each chain under study by formulating the data in the major databases so that the Well-to-Tank processes covered Feedstock Production, Feedstock Transport, Fuel Production and Fuel Distribution. With the addition of Tank-to-Wheel data, a comprehensive STM was obtained for each chain. For each stage there is a range of values that was characterized by a probability distribution and through the use of Monte Carlo simulation the distribution was sampled and overall values for the total energy consumption, in MJ/km, and total GHG emissions in grams of carbon dioxide equivalent per kilometre (gCO2eq/km) were generated. By statistical means these distributions were compared to assess the risk of debt as well as the likelihood of major savings if they were to be implemented. The scope of the analysis was limited to passenger cars transport and does not include other forms of road transport. Major classic WtW models may account for subjective uncertainty in the input parameters of the model but with a default set of inputs which represents only one database and one set of modelling assumptions and choices. This individualism and determinism in the WtW modelling nowadays explains the significant discrepancies that arise across the results from different models. The level of variation presented poses a major problem in the context of policy making and strategic planning. The generation of the STM rests upon the convection that a synthesis which generates a statistically relevant aggregate of the different WtW results from the different models of the major expert groups would eliminate the present inconsistencies and deliver the reliability required for making robust strategic decisions. Advantage was taken of the richness of the STM outputs to assess the sensitivity of the results and identify the major factors of disagreement within the expert systems. Here the STM presents the largest platform of comparison and the most comprehensive evaluation of the different WtW models in the field. The provision of such a sensitivity analysis was not possible without allowing for variation in the elements of the model as done using the STM. Secondly, the key outputs of the model were compared under the criterion of sustainability from both energy and environmental perspectives. This was done by the synthesis of a first-of-its-kind distribution of the difference between the conventional system and the alternative system for each option under study. The output reflects as complete a population as possible of what may occur in reality in terms of direct impact on sustainability. This method of comparison was not possible without synthesizing an aggregate of possibilities as done using the STM. Thirdly, synergies with the power sector were studied to identify which strategies delay the global reduction in GHG emissions and which are to be preferred from an overall perspective. Here the author lead the transport research community in looking on the global benefits of alternative transport systems, rather than only looking through the window of the transport sector, by redrawing the boundary for the analysis of prospective transport systems. Last and not least, the outcomes of the comparative analyses of the STM results were aggregated into a proposed strategic framework for carbon and energy reduction in passenger cars transport. The strategic framework is placed into perspective by building a set of future scenarios and scaling the effect for the progressive implementation of these scenarios and making a comparison with the business-as-usual forecast. The creation of an energy economy based on hydrogen fuel was found to be a highly questionable objective because electrically driven vehicles are superior with regard to systems that are either nuclear resourced or based on non-biomass renewables. For hydrogen, only the option from waste wood via gasification was found to be very attractive. However because only a minor role for hydrogen is foreseen, it is envisaged that the development of a hydrogen infrastructure would not be feasible. Therefore the use of hydrogen will be constrained to decentral systems or central systems with liquid hydrogen distribution. With regard to cultivated biomass, the sugar ethanol options are the best in terms of land use with sugarcane having the advantage of being economic and available for short-term penetration. The safe implementation of sugar ethanol, which includes avoidance of CO₂ emissions from indirect land use change and low fertilizers use, guarantees significant savings and have a good potential for large CO₂ emissions savings. Generally due to land use limitation cultivated biomass based options cannot be sustained on the long term. Last and not least, the CO2 emissions savings from clean coal technology is questionable without CCS technology and even though with the implementation of CCS no significant savings are certain. On the other hand, besides the transport sector the power sector is another major sector of energy resource consumption and careful consideration of any synergies between the sectors is essential for the completeness of the analysis. The strategy in which the use of alternatives such as NG, nuclear and renewables is not diversified but fed only into the power sector is to be preferred as this avoids possible CO₂ emissions from indirect resource use change, and it also isolates the power market to maintain upstream energy security. Finally, the answer to whether it is still possible to save the World from the disastrous consequences of Global Warming is a preliminary "yes" but requires the development and implementation of a complete technology package including nuclear power which is widely debated at the present.

YesOwing to their small size, good wettability, uniform dispersion ability and high thermal properties, the nickel-plated carbon nanotubes (Ni-CNTs) with different aspect ratios are used to reinforce reactive powder concrete (RPC) through modifying the nano/micro- structural units of concrete. Incorporating only 0.075 vol% of Ni-CNTs (0.03 vol% of CNTs) can significantly increase mechanical properties of RPC. The enhancement effect on compressive strength caused by the incorporation of Ni-CNTs with aspect ratio of 1000 reaches 26.8%/23.0 MPa, mainly benefiting from the high polymerization C-S-H gels, low porosity, and refined pore structure. The 33.5%/1.92 MPa increases of flexural strength can be attributed to the decrease of large pore, original cracks, molar ratio of CaO to SiO2, and gel water content when Ni-CNTs with aspect ratio of 125 are added. Ni-CNTs with aspect ratio of 1500 have the largest utilization rate of being pulled-out, resulting from the improvement of dispersibility and the pining effect of nickel coating and then leading to the increased toughness. Therefore, incorporating Ni-CNTs can fundamentally modify the nano/micro- scale structural nature of RPC, providing a bottom-up approach for controlling the properties of RPC.

Full textAbstract:
Due to their large torque-speed ratio and transmission efficiency, planetary gears are widely used in the automotive industry. However, high amplitude vibrations remain their critical weakness, which limits their usage especially when new strict noise legislations come into action. A new approach to handle the instability problems of planetary gears encountered in real industrial context is presented in this work. First, the dynamic response of a planetary gear failing to pass the noise regulations is theoretically investigated through an analytical model. The equations of motion were solved using the Spectral Iterative Method. The observed experimental results correlated well with those from the developed model. In order to limit the resonance phenomena, impacts of different macro and micro-geometry modifications were analytically investigated: quadratic teeth profile, different planets positioning, different number of teeth and number of planets. Optimum modifications were retrieved and are expected to be tested experimentally on a test bench and on the truck. Finally, the analytical model’s limits and sensitivity to different parameters were investigated in order to certify its reliability, and suggestions for improvements were presented.

Purpose: This research work is to discuss the various forces/ factors that affect the business environment of Ghana which impacts investing in marketing and processing of cocoa beans in Ghana. In order to determine or classify Ghana as an attractive destination or otherwise to invest in cocoa marketing and processing there is the need to discuss the prevailing macro business environmental forces which little is known about to investors, managers and policy makers in cocoa trade. These mentioned parties have been under increasing pressures to assess the various forces prevailing in Ghana before considering investing in cocoa marketing and processing in Ghana. The work therefore looks as the various macro environmental factors Political, Economic, Social, Technological, Physical Environment and Legal (PESTEL) forces in Ghana’s business environment which impacts cocoa marketing and processing which makes Ghana an attractive base or otherwise to invest in cocoa marketing and processing.
Research Questions: The specific questions that the research aims at solving are as follows: what are the external and environmental forces that will influence investing in cocoa marketing and processing in Ghana? Is Ghana a safe and attractive base to invest in cocoa marketing and processing?
Research method: In carrying this research I made use of both secondary and primary data. Primary data was gathered through face interviews and administrating questionnaires to illicit response from stakeholders in Ghana’s cocoa. The paper also presents a review of literature on PESTEL which has influence or features in Ghana’s business environment which are important in cocoa marketing and processing.
Research Findings: Empirical findings and review of PESTEL model reported in the work suggests that the PESTEL will impact on the strategy of organizations and policy makers who are into cocoa marketing and processing. Also gives suggestions on how the various environmental forces (PESTEL) will be applied to further improve upon the business environment which makes marketing and processing of cocoa in Ghana attractive.
Research Implications and Limitations: The discussions and analyses of the macro environmental forces prevailing in Ghana’s business environment which impacts cocoa marketing produces a frame work to analyze current threats and opportunities in Ghana’s business environment which impacts cocoa marketing and processing for people contemplating on investing in marketing and processing of cocoa in Ghana as well as other practical lessons for policy makers in cocoa. The work overlooks the micro environmental forces in Ghana that impacts cocoa marketing and processing. Further research into such area will help give an understanding of the micro factors that impact the business environment of Ghana. Also the work has a limited empirical data base as most information gathered were inconsistent and unreliable which raises concerns about investment information. These have been minimized thro3ugh cross checks with primary data.

This thesis proposes a framework for architectural analysis of a system at the Macro and Micro levels. The framework consists of two phases -- Formulation and Analysis. Formulation is made up of three steps -- Identifying the System Boundary, Identifying the Object-Process System levels using the Object-Process Methodology (OPM) and then creating the Dependency Matrix using a Design Structure Matrix (DSM). Analysis is composed of two steps -- Macro-Level and Micro-Level Analysis. Macro-Level analysis identifies the system modules and their interdependencies based on the OPM and DSM clustering analysis and Visibility-Dependency Signature Analysis. The Micro-Level analysis identifies the central components in the system based on the connectivity metrics of Indegree centrality, Outdegeree centrality, Visibility and Dependency. The conclusions are drawn based on simultaneously interpreting the results derived from the Macro-Level and Micro-Level Analysis. Macro-Analysis is vital in terms of comprehending system scalability and functionality. The modules and their interactions influence the scalability of the system while the absence of certain modules within a system might indicate missing system functionality. Micro-Analysis classifies the components in the system based on connectivity and can be used to guide redesign/design efforts. Understanding how the redesign of a particular node will affect the entire system helps in planning and implementation. On the other hand, design Modification/enhancement of nodes with low connectivity can be achieved without affecting the performance or architecture of the entire system. Identifying the highly central nodes also helps the system architect understand whether the system has enough redundancy built in to withstand the failure of the central nodes. Potential system bottlenecks can also be identified by using the micro-level analysis. The proposed framework is applied to two industry leading Smart Grid Meter Data Management Systems. Meter Data Management Systems are the central repository of meter data in the Smart Grid Information Technology Layer. Exponential growth is expected in managing electrical meter data and technology firms are very interested in finding ways to leverage the Smart Information Technology market. The thesis compares the two Meter Data Management System architectures, and proposes a generic Meter Data Management System by combining the strengths of the two architectures while identifying areas of collaboration between firms to leverage this generic architecture.

Full textAbstract:
This thesis was inspired by my MA Dissertation back in (2007). This dissertation dealt with 'situationality'. After a couple of years, there was a need to explore other aspects of translation. This study investigates the role of micro and macro levels in the translation of a sample of Modern Standard Arabic proverbs into English. These proverbs may not be understood if a translation focuses on the micro level, i.e. the surface features of the proverbs such as semantics, syntax and style, without taking into account the macro level, i.e. the socio-cultural context for the proverbs. Therefore, the solution suggested in this study is to translate their micro levels as well as their macro surroundings in order to convey their meaning to speakers of English. This study had two main aims: to assess students’ ability to translate the selected proverbs and to convey the meanings of these proverbs to native English speakers. To achieve these aims, twenty Modern Standard Arabic proverbs were selected on the grounds that they deal with various subjects and are widely used in Arab culture. A randomly chosen sample of fourth-year students from the Department of English at Benghazi University were asked to translate these proverbs into English and their translations were then analysed at micro and macro levels. At the micro level, three main types of errors were identified: semantic, syntactic and stylistic. The study found that most of the students in the sample faced difficulties when asked to translate proverbs from their mother tongue into English. The use of error analysis provided possible solutions and suggestions for assessing the students’ requirements and needs in a particular training situation in terms of the real text being translated. During this analysis, deficiencies in translation skills were identified and evaluated, and appropriate translations by native English speakers were provided to show alternative translations of these proverbs. At the macro level, a number of problems relating to student translations of the context of the proverbs were identified. The study recommends that translation of this feature is necessary in order to convey their meaning to English native speakers. The study shows that when the situation and context for a proverb are not provided, it becomes meaningless and difficult to comprehend.

Full textAbstract:
INTRODUÇÃO: O tema de investigação, discurso de afásicos, fornece informações importantes sobre aspectos fonológicos, morfológicos, sintáticos, semânticos e pragmáticos da linguagem de pacientes que sofreram lesão vascular cerebral. Uma das maneiras de estudar o discurso é por meio de cenas figurativas temáticas simples ou em sequência. A sequência da história de \"Cinderela\" é frequentemente utilizada em estudos, por ser familiar em todo o mundo, o que favorece estudos transculturais; por induzir a produção de narrativas, ao invés de descrições, frequentemente obtidas quando se utiliza prancha única para eliciar discursos. Outra vantagem do uso das sequências da \"Cinderela\" é o fato de gerar material linguístico em quantidade suficiente para análise detalhada. OBJETIVOS: (1) analisar, por meio de tecnologias computadorizadas, aspectos macro e microestruturais do discurso de indivíduos sadios do ponto de vista cognitivo, afásicos de Broca e afásicos anômicos; (2) explorar o discurso como indicador de evolução da afasia; (3) analisar a contribuição do SPECT para verificação de evolução da afasia junto ao discurso. MÉTODO: Participaram do estudo oito indivíduos afásicos de Broca e anômicos que compuseram o grupo do estudo longitudinal (G1), 15 indivíduos afásicos de Broca e anômicos que compuseram o outro grupo de estudo (G2) e 30 cognitivamente sadios (GC). Os participantes foram solicitados a examinar as cenas da história \"Cinderela\" e depois recontar a história, com suas palavras. Foram exploradas tecnologias computadorizadas e analisados aspectos macro e microestruturais dos discursos produzidos. Para o G1, tivermos a particularidade de coleta de discurso também pela prancha \"Roubo dos Biscoitos\", análise do exame SPECT e acompanhamento longitudinal por um período de seis meses. RESULTADOS: Comparando o GC e o G2, em relação à macroestrutura, notou-se que os afásicos do G2 se diferenciaram significativamente do GC em todas as proposições e, em relação à microestrutura, sete métricas foram capazes de diferenciar ambos os grupos. Houve diferença significante macro e micro estrutural entre os sujeitos afásicos de Broca e anômicos. Foi possível verificar diferenças em medidas da macro e da microestrutura no G1 com o avançar do tempo de lesão após AVC. A história da \"Cinderela\" forneceu dados de microestrutura mais completos do que a prancha \"Roubo dos Biscoitos\". Os resultados do SPECT permaneceram os mesmos, sem demonstração de mudança com a evolução da afasia. CONCLUSÃO: A produção de narrativa gerou material para análise de macroestrutura e microestrutura, tanto aspectos de macro quanto de microestrutura diferenciaram indivíduos cognitivamente sadios dos sujeitos afásicos. A análise do discurso da \"Cinderela\" serviu como instrumento para mensurar a melhora da linguagem dos sujeitos afásicos. O uso da ferramenta computacional auxiliou as análises discursivasINTRODUCTION: The aphasic discourse analysis provides important information about the phonological, morphological, syntactic, semantic and pragmatic aspects of the language of patients who have suffered a stroke. The evaluation of the discourse, along with other methods, can contribute to observation of the evolution of the language and communication of aphasic patients; however, manual analysis is laborious and can lead to errors. OBJECTIVES: (1) to analyze, by computerized technologies, macro and microstructural aspects of the discourse of healthy cognitive individuals, Broca\'s and anomic aphasics; (2) to explore the discourse as indicator of the evolution of aphasia; (3) to analyze the contribution of single photon emission computed tomography (SPECT) to verify the correlation between behavioral and neuroimaging evolution data. METHOD: Two groups of patients were studied: GA1, consisting of eight individuals with Broca\'s aphasia and anomic aphasia, who were analyzed longitudinally from the sub-acute phase of the lesion and after three and six months; GA2 composed of 15 individuals with Broca\'s and anomic aphasia, with varying times of stroke installation and GC consisting of 30 cognitively healthy participants. Computerized technologies were explored for the analysis of metrics related to the micro and macrostructure of discourses uttered from Cinderela history and Cookie Theft picture. RESULTS: Comparing the GC and GA2, in relation to the discourse macrostructure, it was observed that the GA2 aphasics differed significantly from the GC in relation to the total number of propositions emitted; considering the microstructure, seven metrics differentiated both groups. There was a significant difference in the macro and microstructure between the discourses of Broca\'s aphasic subjects and anomic ones. It was possible to verify differences in macro and microstructure measurements in GA1 with the advancement of injury time. In GA1, the comparison between parameters in the sub-acute phase and after 6 months of stroke revealed differences in macrostructure - increase in the number of propositions of the orientation block and of the total propositions. Regarding the microstructure, the initial measures of syllable metrics by word content, incidence of nouns and incidence of content words differed after 6 months of intervention. The variable incidence of missing words in the dictionary showed a significantly lower value after three months of stroke. Cinderella\'s story provided more complete microstructure data than the Cookie Theft picture. There was no change in SPECT over time, without demonstration of change with the evolution of aphasia. CONCLUSION: The discourse produced from the history of Cinderella and the Cookie Theft picture generated material for macrostructure and microstructure analysis of cognitively healthy and aphasic individuals, made it possible to quantify and qualify the evolution of language in different phases of stroke recuperation and distinguished the behavior of healthy and with Broca´s and anomic aphasia, in macro and microstructure aspects. The exploration of computerized tools facilitated the analysis of the data in relation to the microstructure, but it was not applicable to the macrostructure, demonstrating that there is a need for tool adjustments for the discourse analysis of patients. SPECT data did not reflect the behavioral improvement of the language of aphasic subjects

Nell'ambito dell'economia dei disastri naturali ho elaborato uno studio macroeconomico e due microeconomici. A livello macro ho elaborato una meta-analisi della letteratura empirica sugli effetti dei disastri naturali in termini di costi diretti e indiretti. Ho analizzato gli effetti di caratteristiche del database,tecniche di stima, fattori di resilienza considerati e publication bias. Studi sui costi diretti che includono paesi Africani hanno 65% maggiore probabilità di riportare un risultato negativo e significativo mentre studi sui costi indiretti sembrano soffrire di publication bias. I lavori microeconometrici si focalizzano su due paesi africani. Nel primo analizzo gli effetti di un aumento della variabilità climatica sul consumo di beni alimentari delle famiglie in Uganda nel periodo 2005/06-2009/10. In media un incremento di 1% delle temperature porterebbe a una diminuzione del consumo di alimenti del 3-5% mentre le famiglie sarebbero in grado di contrastare variazioni delle precipitazioni con varie strategie. Nel secondo, con approccio multi-shock analizzo gli effetti di siccità e incremento dei prezzi di acquisto sullo stato nutrizionale di bambini in famiglie residenti in zone rurali del Senegal nel periodo 2009-2011. Singolarmente entrambi gli eventi sembrano avere effetti negativi sul livello nutrizionale. Tuttavia la concomitanza dei due eventi sembra non avere effetto sul peso dei bambini grazie a un positivo effetto reddito.In this work I deal with the economics of natural disasters conducting one study at the macroeconomic level and two studies at the microeconomic level. In the first I conduct a meta-analysis of the macro literature on the direct and indirect costs of natural disasters. I investigate the effects of empirical design, estimation technique, resilience factors included and publication bias. I find that direct costs studies have 65% probability to report negative and significant results if they include African countries while indirect costs studies show publication bias. Second, I conduct a microeconometric analysis of the effects of weather variability on households food consumption in Uganda in the period 2005/06-2009/10. I show that on average 1% increase in maximum temperatures would reduce food consumption by 4-5% while precipitation amount and distribution would not affect household food consumption thanks to coping strategies. Finally I consider the effects of droughts and increasing purchasing prices on weight-for-age of children in rural households in Senegal using a multishock approach and a unique dataset (2009-2011). Results of drought(increase in prices) econometric analyis show deterioration in child weight-for-age. However, concomitance of drought and increasing prices would leave child weight-for-age unaffected thanks to positive income effects.

Full textAbstract:
Esta tesis doctoral se ha llevado a cabo con la finalidad de explorar la espacialidad de las evidencias materiales preservadas en la superficie del palafito del Villaggio delle Macine. El yacimiento, fechado entre Bronce Antiguo final y Bronce Medio inicial, se localiza en la Italia central. Un aproche geoestadístico, aplicado al análisis espacial intra-site, ha proporcionado las herramientas necesarias para poder discernir el patrón observado. El mismo, podría estar reflejando o bien la distribución espacial originaria de las actividades sociales llevadas a cabo durante la última fase de ocupación del yacimiento o bien, podría ser el resultado de potenciales procesos post-depositacionales (Capítulo 1). Diferentes perspectivas han sido analizadas para así, dar solución a la pregunta principal.
En los Capítulos 2 y 3 un detallado resumen de los procesos de formación y deformación del depósito arqueológico ha mostrado como estos son indispensables para la interpretación de los patrones espaciales. Numerosos ejemplos, procedentes de contextos arqueológicos de distintas localizaciones, han recalcado la magnitud del aproche; el Capítulo 3 se centra en exclusiva en el análisis de los procesos de formación y deformación que interesan (y afectan) a los palafitos. El enfoque interdisciplinar planteado en ambos Capítulos 2 y 3 ha permitido a los arqueólogos “viajar en el tiempo”, diseccionando el palimpsesto preservado, objeto del análisis.
En los Capítulos 5 y 6 se presenta y contextualiza el yacimiento en el marco del Bronce medio de la Italia Central. Se reconstruye el entorno natural que acogió el palafito y los procesos que formaron parte de su formación (y potencial deformación), a través de un análisis biográfico. En el Capítulo 6 se presentan los artefactos (y ecofactos) hallados en excavaciones y prospecciones, describiendo por cada categoría los problemas relativos de conservación y la información arqueológica aportada. El análisis se centra en los hallazgos de las prospecciones que constituyen la base de datos tratada para esta tesis. Además en el Capítulo 6 se presenta también, una reflexión teórica sobre las prospecciones superficiales en relación a sus puntos fuertes y debilidades considerando los estudios anteriormente realizados. De esa manera es posible resaltar las dificultades que estas técnicas de investigación conllevan y sus potenciales limitaciones.
La tercera sección de esta tesis se focaliza en el análisis intra-site y en la geoestadística (Capítulos 4, 7, 8 y 9). El protocolo analítico propuesto y unas reflexiones iniciales caracterizan el Capítulo 4, mientras que en el 7, 8 y 9 presentan los análisis (y sus interpretaciones) realizados según la campaña de prospección. Finalmente, en el Capítulo 10 se discuten los resultados obtenidos que nos permiten contestar a la pregunta principal expresada en el Capítulo 1. La hipótesis que considera el patrón espacial observado como resultado de procesos post-depositacionales puede ser rechazada. Por consiguiente, aunque estos procesos puedan haber modificado, parcialmente, el patrón espacial original algunos rastros nos permiten inferir respecto la organización del espacio en el yacimiento durante su última fase de ocupación.This thesis is aimed to explore the spatiality of material evidence retrieved on the surface of the italian Bronze Age pile-dwelling of Villaggio delle Macine. A geostatistic approach, applied to intra-site spatial analysis, provides required tools to analyze the observed spatial pattern; this can mirror the original placement of social activities at the settlement during its last phase of occupation, or, conversely, it can be produced by potential post-depositional processes (Chapter 1). In an attempt to wondering such main question, different perspectives have been taken into account. Within Chapters 2 and 3 it is highlighted the importance of reconstruct the formation (and deformation) of the archaeological record, through a deepen analysis of the state of the art concerning this theme; supporting such assumption, several examples from different archaeological contexts scattered all over the world are introduced. In Chapter 3 this perspective is stressed focusing on lakeside settlement contexts. An interdisciplinary approach (Chapter 2 and 3) proved to allow archaeologists to “travel backward”, dissecting the preserved archaeological palimpsest under analysis. Chapters 5 and 6 are devoted to introduce and contextualize the site of Villaggio delle Macine in the framework of Middle Bronze Age in Central Italy, reconstructing the natural environment where the settlement has been hosted and the formation (and potential deformation) of the site itself, through a biographical approach (Chapter 5). Within Chapter 6, all categories of material evidence retrieved at the site during both excavations and surveys are described, highlighting, for each category, the issues related to their condition of preservation and the archaeological information derived from their analysis. Furthermore, a theoretical reflection concerning the surface surveys, in terms of their strengths and weakness, is introduced through a short summary of the state of the art. In this way further light is shed on the bias associated with archaeological surface surveys and their potential limitations. Finally, the dataset is extensively described in this chapter. The third section of this thesis is focused on the intra-site spatial analyses and geostatistics (Chapters 4, 7, 8 and 9). Theoretical reflections as well as the analytical procedure proposed there are described in Chapter 4, while Chapters 7, 8 and 9 are devoted to the detailed analyses performed for each survey campaigns. In Chapter 10 the discussion of all these results allows to wonder the main questions presented in Chapter 1; the starting null hypothesis which considered the observed spatial pattern as result of post-depositional processes can be rejected. Indeed, such disturbance could have provoked some spatial modification of the original pattern, but it is however preserved in such a way that allows reconstructing the organization of the space within the settlement during its last phase of occupation.

Les mousses de polyuréthane (PU) hautement poreuses sont largement utilisées dans différentes
industries pour dissiper l’énergie des ondes sonores et vibratoires. La propagation
des ondes acoustiques dans ces matériaux poroélastiques est décrite à partir d’un ensemble
de paramètres physiques connus sous le nom de paramètres de Biot (pour les matériaux
isotropes, ils sont composés de 5 paramètres non acoustiques et de 4 paramètres mécaniques).
Il est bien connu que les propriétés macroscopiques dépendent intrinsèquement
des propriétés de la microstructure de la mousse. Ainsi, une compréhension claire des corrélations
entre la structure interne des mousses de PU et leurs paramètres de Biot ainsi
que la contribution de chaque paramètre, soit microscopique ou macroscopique, sur l’indicateur
vibroacoustique désiré est d’un intérêt majeur au stade précoce de la conception et
de l’optimisation de ces matériaux poroélastiques. Le développement d’un modèle micromacro
qui corrèle les propriétés de la microstructure aux paramètres macroscopiques de
Biot est donc nécessaire.
Récemment, un modèle qui corrèle les propriétés de la microstructure des mousses PU
hautement poreuses à leurs propriétés non acoustiques a été présenté par Doutres et coll.
[24, 25]. Dans cette étude, les propriétés de la microstructure (dimensions de la cellule et
taux de réticulation) sont d’abord caractérisées par un microscope électronique à balayage
(SEM). Ensuite, l’effet du taux de réticulation (mesurant le pourcentage de fenêtres ouvertes),
de la taille des cellules et de la densité relative sur les propriétés mécaniques de
la mousse de polyuréthane a été élucidé à l’aide d’un modèle numérique. Se basant sur
ce modèle, un modelé analytique existant, qui corrèle les propriétés de la microstructure
de mousses PU entièrement réticulées à ses propriétés mécaniques, a été revu et corrigé
pour tenir compte de l’effet important du taux de réticulation. En combinant le modèle
de Doutres avec le modèle mécanique développé dans cette thèse, un modèle micro-macro
complet est ainsi obtenu. Utilisant ce modèle, l’impact de la variabilité de la microstructure
et la contribution de chacun des paramètres microstructuraux à la réponse vibroacoustique
ont été étudiés utilisant une méthode d’analyse de sensibilité globale (FAST). La méthode
FAST a été utilisée pour identifier l’impact de la microstructure sur, premièrement, les
paramètres de Biot-Allard et, deuxièmement, sur les indicateurs vibroacoustiques (absorption
et perte par transmission) des mousses de polyuréthane poroélastiques. Une fois les
modèles micro-macro et la contribution des propriétés de la microstructure connus, la
performance vibroacoustique de la mousse a été optimisée. Ainsi nous avons testé numériquement
la performance acoustique de mousses homogènes et de mousses graduellement
structurées (variation de propriétés suivant l’épaisseur de la mousse). Cette étude ouvre
ainsi de nouvelles portes pour concevoir des mousses PU innovantes avec une microstructure
modifiée et des performances vibroacoustique améliorées.Abstract : Highly porous polyurethane (PU) foams are widely used in different industries to dissipate the energy of sound and vibration waves. Propagation of acoustic waves in such poroelastic materials is explained based on a set of physical parameters known as the Biot's parameters (for isotropic materials these are comprised of 5 non-acoustical parameters and 4 mechanical parameters). These macroscopic properties are inherently dependent on the microstructure properties of the foam. Hence, a clear understanding of correlations between the internal structure of PU foams and their Biot's parameters and the contribution of each parameter, either microscopic or macroscopic, to classical vibro-acoustic indicators is of utmost interest at the early stage of design and optimization of such poroelastic materials. In consequence, a micro macro model that correlates microstructure properties to macroscopic Biot's parameters is needed. Recently, a model that correlates the microstructure properties of highly porous PU foams to their non-acoustical properties was presented by~\citet{Doutres2011,Doutres2013}. In this study, micro-structure properties (strut length, strut thickness, and open pore content) are first characterized using a Scanning Electron Microscope (SEM). Then, a numerical study is performed to elucidate the effect of open pore content (known as reticulation rate), cell size, and relative density on the mechanical properties of polyurethane foam. Based on this study, an existing analytical model~\cite{Gong2005} that correlates fully reticulated unit cell microstructure properties of PU foams to its mechanical properties is corrected and updated to account for these important parameters. Combined with Doutres’ model, the proposed extension lead to a full micro-macro model for predicting the acoustic performance of PU foams from its microstructure. Using this model, the contribution of the unit cell parameters and effect of their variability on classical vibro-acoustic indicators (absorption and transmission loss) is investigated using a global sensitivity analysis method (FAST). The FAST method is used to identify the impact of microstructure role on, first, the Biot-Allard parameters and, second, on vibro-acoustical indicators of poroelastic polyurethane foams. Based on this sensitivity analysis study, the developed micro-macro model, is used to design both optimum homogeneous foam and functionally graded foams (properties optimally varnish along the thickness of the foam) targeting specific in absorption and/or transmission loss problems. This study opens thus a new door to design innovative PU foams with modified micro-structure and improved vibro-acoustical performance.

Un des objectifs prioritaires des industries aéronautiques est la réduction de la masse des structures, tout en permettant l'amélioration de leurs performances. Ceci passe notamment par l'utilisation de matériaux composites et le recours croissant à la simulation numérique, permettant la minimisation du nombre d'essais physiques et l'optimisation des structures.L'enjeu de ces travaux est de pouvoir calculer précisément, sur des matériaux architecturés, l'influence de la microstructure, modélisée par exemple directement par tomographie, sur la tenue de pièces complètes. Pour prendre en compte à la fois l'ensemble de la pièce et les effets de son chargement, une approche global/local multiéchelle semble adaptée tant du point de vue des méthodes de calcul que des modèles matériaux utilisés.Pour répondre à cette problématique, une méthode de couplage entre des modèles qui décrivent une même structure, mais à des échelles différentes, a été développée. Elle repose sur une séparation micro-macro des quantités d’interface, dans la zone de raccord surfacique entre les deux modèles. Pour faciliter son utilisation dans les bureaux d’étude, une technique de résolution itérative non-intrusive est également présentée. Elle permet de mettre en œuvre la méthode de couplage proposée dans un environnement logiciel industriel qui utilise bien souvent des codes éléments finis commerciaux fermés. La méthode est systématiquement comparée à d'autres méthodes de couplage de la littérature et la qualité des solutions est quantifiée par comparaison à une solution de référence obtenue par un calcul direct à l'échelle fine.Les principaux résultats sont encourageants dans la mesure où ils montrent, dans des cas d'étude représentatifs bidimensionnels et tridimensionnels, sous des hypothèses d’élasticité linéaire, des solutions cohérentes avec les théories de l’homogénéisation au premier et second ordre. De fait, les solutions obtenues sont systématiquement de meilleure qualité avec la méthode proposée qu'avec les méthodes de la littérature, non-adaptées à des cas de couplage pour modèles non-compatibles.Finalement, les perspectives sont multiples en raison des différentes alternatives de la méthode qui, dans un contexte industriel, pourrait offrir un véritable outil d'analyse visant à introduire un modèle local décrit à l'échelle fine dans un modèle global macroscopique homogénéiséOne of the priority objectives of the aeronautics industry is to reduce the mass of structures while improving their performances. This involves the use of composite materials and the increasing use of digital simulation to optimize structures.The major challenge of this project is to be able to accurately calculate the local variations of the microstructure - for instance detected by tomography and directly modelled from tomogram - on the behavior of an architectured material part. In order to take into account the whole structure and its load effects, a multi-scale approach seems to be a natural choice. Indeed, the related models to the part and its microstructure might use different formalisms according to each scale.In this context, a coupling formulation was proposed in order to replace, in a non-intrusive way, a part of a homogenized macroscopic finite-element model by a local one described at a microscopic level. It is based on a micro-macro separation of interface quantities in the coupling area between the two models. To simplify its use in design offices, a non-intrusive iterative resolution procedure has also been proposed. It allows the implementation of the proposed coupling method in an industrial software environment that often uses closed commercial finite element codes. Different mechanical problems under linear elasticity assumption are proposed. The proposed method is systematically compared with other coupling methods of the literature and the quality of the solutions is quantified compared to a reference one obtained by direct numerical simulation at a fine scale.The main results are promising as they show, for representatives test cases under linear elasticity assumption in two and three-dimensions, solutions that are consistent with first- and second-order homogenization theories. The solutions obtained with the proposed method are systematically the best approximations of the reference solution whereas the methods of the literature are less accurate and shown to be unsuitable to couple non-compatible models.Finally, there are many perspectives due to the different alternatives of the method which could become, in an industrial context, a real analytic tool that aims to introduce a local model described at a fine scale, into a homogenized macroscopic global one

Full textAbstract:
Les ménages sont responsables d’une part significative des consommations d’énergie et des émissions de CO2, en particulier si l’on tient compte des consommations d’énergie et des émissions indirectes liées aux processus de production des biens et services consommés. Plusieurs travaux scientifiques et recommandations d’organisations gouvernementales et d’associations non-gouvernementales soulignent que des modifications des modes de consommations seront sans doute nécessaires pour atteindre les objectifs climatiques fixés aujourd’hui. Notre thèse propose une méthode d’analyse prospective de changements de mode de vie, qui permet d’en estimer les impacts macro-économiques ainsi que ceux sur les consommations d’énergie et les émissions de CO2, tout en tenant compte de l'hétérogénéité des ménages en matière de comportements et de consommations d'énergie. Notre méthode explore les modes de consommation des ménages de manière fine, en prenant en considération le lien entre emplois du temps et consommations. En effet, les choix de consommation sont soumis non seulement à des contraintes de budget, mais également à des contraintes qui dérivent du temps à disposition et qui ne sont jamais prises en compte dans la prospective macro- économique. Nous construisons une base de données détaillant emplois du temps, dépenses et consommations d’énergie des ménages français et nous l’articulons à un modèle de prospective économique énergie-émissions par un processus de repondération itératif. Nous illustrons la portée de cet outil à travers l’analyse de trois scénarios, centrés respectivement sur la diffusion de nouvelles formes de mobilité (covoiturage et autopartage), la généralisation des achats en ligne et le retour vers le faire soi-même en matière d'alimentation. Pour les trois scénarios nous observons des réductions des consommations d’énergie et des émissions de CO2. Par exemple, les émissions totales diminuent de 2,3% en 2050 dans le scénario sur la mobilitéHousehold energy consumption represents a significant share of final energy use, especially when both direct and embodied energy are taken into account. Several academic studies, as well as the recommendations of the United Nations and of non-governmental organisations, suggest that a shift in consumption patterns will be necessary to achieve sustainable development. The aim of our research is to analyse long-term scenarios of changes in lifestyle. We propose a methodology that allows to analyse the macro-economic impacts of these changes, as well as the impacts on energy use and CO2 emissions, while taking into account the heterogeneity of behaviours and energy consumptions among households. Consumption choices do not derive solely from monetary considerations but they are influenced by several factors. One binding constraint, never taken into account in macro-economic energy modelling, is the available time. For this reason, our analysis considers time use data in addition to expenditure and energy use data. We build a data base that combines time use, expenditure and energy consumption data for French households, which provides detailed information about household consumption patterns. Then, for scenario analyses, we link the data base with an Energy-EconomyEmissions model, using an iteration process based on a reweighting technique. We illustrate the methodology by exploring three areas of change in consumption patterns: cooking habits, ecommerce and shared transport (carpooling and car sharing). We obtain CO2 emissions reductions in all scenarios. As an example, emissions decrease by 2.3% by 2050 in the scenario focusing on transport

Full textAbstract:
The research offered in this submission presents the case for a PhD by portfolio and is presented in two parts: an 'Overview' and 'The Evidence'. It explores the synergies between resource planning, sustainability, and regeneration policy associated with the development of tourism. These processes are linked particularly with environmental and cultural resource issues within European and global contexts as well as more specific planning issues within the UK and Wales. Three projects are presented; they address culture and environmental tourism themes in project 1, specific interests in urban planning, regeneration and tourism in project 2, and rural tourism issues in project 3. The projects follow a chronological course that illustrates how the research has progressed between 1995 and 2003. They show development from an initial broad interest in planning and sustainable development issues, to more focussed work on heritage and cultural tourism niche markets within more recent urban and rural contexts. The findings from the projects explore notions of planning, regeneration, sustainability and the relationships and synergies that occur between these processes and the development of specialist tourism. The research conclusions from all three projects suggest there still remain critical policy, resource planning and management issues for achieving sustainability, protecting resources and developing new tourism opportunities. This is particularly pertinent for the effective implementation of sustainable tourism. Issues concerning the development of niche tourism markets as a sustainable option have been a key research focus. Concerns are raised regarding the role of planning policy, long term strategy, institutional support for sustainable tourism, empowerment of local communities, and tensions between market priorities vis-a-vis conserving environmental and cultural resources. The degree of 'trade off between these often conflicting policy goals are also discussed. In a broader context, evidence from the projects document the changing dimensions of planning, regeneration and sustainable development and tourism policies over nearly a decade and draw conclusions on the challenges still confronting these processes today. In this respect evidence from the projects shows that there is generally more divergence than convergence in policy initiatives which encourage tourism development linked to sustainability. This is particularly the case when alternative forms of tourism are considered. The main conclusion synthesised from the projects illustrate that the development of alternative tourism will challenge resourcing and planning activities as these markets look set to grow over the next decade. The portfolio proposes that developing a framework to ensure the successful implementation of new sustainable tourism markets will make strategic planning an increasingly important priority and a future focus for tourism research in this respect. The emerging and fairly recent concept of 'cultural regeneration' is proposed as a focus for this further research.

"What is the relationship between macro and micro level perceptions towards the work environment and occupational stress ; can positive psychological states help mediate this relationship? : evidence from a multinational pharmaceutical company." Thesis, Lancaster University, 2011. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.618332.
Full textAbstract:
This study explores one of the most prevalent and influential models of occupational stress. The central aim was to explore the extent to which this model could be extended to incorporate broader organizational climate and culture factors as well as more positively orientated mediating phenomena. Occupational stress has been the focal point of research and practice for several decades. However in recent times this research has been criticised for focusing primarily on the individual level of analysis, not acknowledging research contributions from outside organizational and health psychology, and studying overly negative orientated phenomena. Consequently this study proposed a conceptual model which expands upon Cooper and Marshall's (1976) infamous model of occupational stress. This conceptual model hypothesised that incorporating broader macro-level factors as potential sources of stress and more positively orientated mediating psychological states could add a meaningful amount of value and further understanding of the occupational stress process. A secondary analysis of a multinational pharmaceutical company's global employee opinion survey was performed to identify and develop a macro-level climate assessment tool. A sample of employees within the same R&D function was then assessed using the same macro-level climate tool as well as two other validated assessment tools, These included a traditional stress risk assessment and a more recent positive psychological assessment tool The study found that both the macro and positive psychological state variables were able to account for a significant proportion of additional variance in psychological well-being and physical health, The study also found some preliminary support for extending Cooper and Marshall's model to incorporate the macro-level factors as sources of stress and positive psychological states as mediators. The final model identified that macro and micro level perceptions appeared to have differing effects upon individual health outcomes through the mediating positive psychological states. It ~as hypothesised that this may be due to the level of proximity of these variables in relation to employees

Title: A Study of Switch Pac: what would be the efficient ways for Switch Pac to increase potential demand and capitalize on green attitudes and behavior in the Swedish market?
Problem: What would be the efficient ways for Switch Pac to increase potential demand and capitalize on green attitudes and behavior in the Swedish market?
Purpose: The aim of our project is to see the potential of Switch Pac’s oxo-biodegradable plastic bags on the Swedish market by capitalize on green attitudes and behaviour.
Method: The report is based on primary data collected through questionnaires (end consumer/ B2B customers). For the investigation of Switch Pac’s macro- and microenvironment secondary data was used (books, journals, newspaper and the Internet)
Conceptual Framework: The conceptual framework consists of certain models to investigate the following topics:
Consumer behavior
AIDA-Model
STP-Model
Switch Pac´s business environment
PESTEL
Conclusion/ Recommendations: In our conclusion based on our frameworks PESTEL, AIDA and STP we concluded that peoples’ awareness regarding environmental friendly plastic bags are not very high based on our questionnaire. The efficient ways for Switch Pac to increase potential demand is to target the customer in the age range from 20 – 49 years and cooperate with supermarkets and (department) stores. Furthermore, Switch Pac needs to position its products in the consumers mind through create brand awareness by using certain elements of the marketing mix model.

Full textAbstract:
The aim of this longitudinal, in-depth, explanatory case study is to develop an integrated view of strategy as a social practice from `macro to micro' in the organisational arena circumscribed by the Welsh Assembly Government, NHS Wales, and its partner agencies. It is therefore centred upon the development of the Lifelong Learning Strategy for NHS Wales. In doing so, Archer's (1995) Morphogenetic-Morphostatic Cycle is used as a framework through which to loop together macro extra-organisational societal forces with micro intra-organisational strategic managerial activities in order to determine their linked interplay in strategising, thereby rising to Whittington's challenge to `complete the practice turn', and thus address a fundamental gap in the extant literature (2006a: 613, 617; 2006b: 1903). Firstly, the macro level paradigmatic and subordinate institutional logics underpinning the reform of the United Kingdom's health care state during the Blair decade (1997-2007) are identified, thereby highlighting the emergence of discordant logics in post-devolution Wales. Secondly, the emergence of the Project Board, tasked by the Welsh Assembly Government with the oversight of the Lifelong Learning Strategy for NHS Wales, is considered. Here, attention is primarily focused upon the positional, professional, role and organisational composition of the Project Board, drawing into consideration the discordant institutional logics, and the power disparity between its elite members. Thirdly, the structural, cultural, and agential emergent properties which manifested during the development of the Lifelong Learning Strategy for NHS Wales are identified. Finally, the macro to micro cascade of generative mechanisms which modulated the development of the Lifelong Learning Strategy for NHS Wales is retroduced, and the situational logic that fostered morphogenesis or morphostasis within the strategic arena is exposed.

Thesis, Luleå tekniska universitet, Mineralteknik och metallurgi, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:ltu:diva-70422.
Full textAbstract:
Lithium represents one of the strategic elements for the rest of the 21st century due to its increasing demand in technological applications. Therefore, new efforts should be focused on the optimization of mineral characterization processes, which link the ore properties with its behaviour during downstream processes. These efforts should result in reducing operational risks and increasing resources utilization. The methodology presented in this study is based on the application of several classification techniques, aiming the mineral and textural characterization of two spodumene pegmatite deposits within the Keliber Lithium Project. Twelve textural classes have been proposed for the textual classification of the ore, which have been defined through the recognition of the main mineral features at macro- and micro-scale. The textural classification was performed through the application of drill core logging and scanning electron microscopy. Six classes are proposed to describe the characteristics of the spodumene ore. Six additional classes describe the main properties of the rocks surrounding the ore zone. Image analysis was implemented for the generation of mineral maps and the subsequent quantification of spodumene and Li2O within the analysed drill core images. The image segmentation process was executed in Fiji-ImageJ and is based on eight mineral classes and a set of seven feature extraction procedures. Thus, quantification of spodumene and Li2O is estimated by textural class. Hyperspectral images were used as a reference for assessing the estimations made through images analysis. A machine learning model in Weka allowed forecasting the behaviour of the twelve textural classes during spodumene flotation. This model is fed by metallurgical data from previous flotation tests and uses Random Forest classifier. The proposed methodology serves as an inexpensive but powerful approach for the complete textural characterization of the ore at Keliber Lithium Project. It provides information about: (1) mineral features at different scales, (2) spatial distribution of textures within the pegmatite body, (3) quantification of spodumene and Li2O within the drill cores and (4) processing response of each textural class. However, its application requires wide knowledge and expertise in the mineralogy of the studied deposits.Thesis Presentation.

Full textAbstract:
The concept of a hub airport has evolved widening its scope as a national civil aviation policy-making tool, due to the ability to deliver wider socio-economic benefits to a country. However, not all airports can be converted into hubs. This research proposes a methodological approach to structural analysis of the airport industry, that could be applied to determine the competitive position of an airport in a given aviation network and devise airport strategies and national policy measures to improve the current position of the airport. This study presents a twelve-group taxonomy of airports, which analyses the changing geography of the airport industry in the East (Asia and The Middle East). Multivariate data have been used in a two-step Agglomerative Hierarchical Clustering exercise which represents three airport strategies: namely, degree-of-airport-activity (size and intensity of operations), network strategies (international and domestic hub), and the market segmentation strategies (service and destination orientation). Principal Component Analysis has been utilised as a data reduction tool. The study confirms the general hypothesis that a sound macro environment and liberalised approach to economic regulation in the air transport industry are important for successful hub operations. In addition, it sheds light on the fact that while the factors of geographical advantage, economic development, urbanisation, tourism and business attractiveness, physical and intellectual infrastructure, and political and administrative frameworks, are all basic prerequisites (qualifiers) for successful hubbing in the region, those factors would not necessarily guarantee a hub status unless the governments are also committed to develop the sector and take timely decisions (differentiators) to allow airports to benefit from the first mover advantage. Application of the proposed taxonomy was tested on a case study of the major international airport of Sri Lanka, to provide policy inputs to develop the airport that is currently identified as being overshadowed by the mega hubs in the region.

Full textAbstract:
During several decades of research and development in the field of Magnetically Confined Fusion (MCF) the preferred selection of materials for Plasma Facing Components (PFC) has changed repeatedly. Without doubt, endurance of the first wall will decide research availability and lifespan of the first International Thermonuclear Research Reactor (ITER). Materials erosion, redeposition and mixing in the reactor are the critical processes responsible for modification of materials properties under plasma impact. This thesis presents several diagnostic techniques and their applications for studies of materials transport in fusion devices. The measurements were made at the EXTRAP T2R Reversed Field Pinch operated in Alfvén laboratory at KTH (Sweden), the TEXTOR tokamak, recently shut down at Forschungszentrum Jülich (Germany) and in the JET tokamak at CCFE (UK). The main outcomes of the work are: Development and application of a method for non-destructive capture and characterization of fast dust particles moving in the edge plasma of fusion devices, as well as particles generated upon laser-assisted cleaning of plasma exposed surfaces. Advancement of conventional broad beam and micro ion beam techniques to include measurement of tritium in the surfaces exposed in future D-T experiments. Adaption of the micro ion beam method for precision mapping of non uniform elements concentrations on irregular surfaces. Implementation of an isotopic marker to study the large scale materials migration in a tokamak and development of a method for fast non destructive sampling of the marker on surfaces of PFCs.QC 20140508
