Full textAbstract:
This thesis focuses on the problem of LiDAR sensor-based mapping where conventional methods has difficulties with the long-term operation or sensor integration. A new mapping system framework has been proposed to overcome the shortcomings of the conventional methods and we demonstrate its advantages on multiple map datasets collected from various environments. The outcome of the research will be useful for several applications where long-term mapping required, such as security robots, autonomous cars, and service robots.

Full textAbstract:
With the advent of Network-Centric Warfare (NCW) concepts, Command and Control (C2) Systems need efficient methods for communicating between heterogeneous systems. To extract or exchange various levels of information within the networks requires interoperability between human and machine as well as between machine and machine. This dissertation explores the Information Exchange Framework (IEF) concept of distributed data fusion sensor networks in Network-centric environments. It is used to synthesize integrative battlefield pictures by combining the Battle Management Language (BML) and System Entity Structure (SES) ontology framework for C2 systems. The SES is an ontology framework that can facilitate information exchange in a network environment. From the perspective of the SES framework, BML serves to express pragmatic frames, since it can specify the information desired by a consumer in an unambiguous way. This thesis formulates information exchange in the SES ontology via BML and defines novel pruning and transformation processes of the SES to extract and fuse data into higher level representations. This supports the interoperability between human users and other sensor systems. The efficacy of such data fusion and exchange is illustrated with several battlefield scenario examples.A second intercommunication issue between sensor systems is how to ensure efficient and effective message passing. This is studied by using Cursor-on-Target (CoT), an effort to standardize a battlefield data exchange format. CoT regulates only a few essential data types as standard and has a simple and efficient structure to hold a wide range of message formats used in dissimilar military enterprises. This thesis adopts the common message type into radar sensor networks to manage the target tracking problem in distributed sensor networks.To demonstrate the effectiveness of the proposed Information Exchange Framework for data fusion systems, we illustrate the approach in an air defense operation scenario using DEVS modeling and simulation. The examples depict basic air defense operation procedure. The demonstration shows that the information requested by a commander is delivered in the right way at the right time so that it can support agile decision making against threats.

Full textAbstract:
At the start of the 21st century, the topic of complexity remains a formidable challenge in engineering, science and other aspects of our world. It seems that when disaster strikes it is because some complex and unforeseen interaction causes the unfortunate outcome. Why did the financial system of the world meltdown in 2008-2009? Why are global temperatures on the rise? These questions and other ones like them are difficult to answer because they pertain to contexts that require lengthy descriptions. In other words, these contexts are complex.
But we as human beings are able to observe and recognize this thing we call 'complexity'. Furthermore, we recognize that there are certain elements of a context that form a system of complex interactions - i.e., a complex system. Many researchers have even noted similarities between seemingly disparate complex systems. Do sub-atomic systems bear resemblance to weather patterns? Or do human-based economic systems bear resemblance to macroscopic flows? Where do we draw the line in their resemblance? These are the kinds of questions that are asked in complex systems research.
And the ability to recognize complexity is not only limited to analytic research. Rather, there are many known examples of humans who, not only observe and recognize but also, operate complex systems. How do they do it? Is there something superhuman about these people or is there something common to human anatomy that makes it possible to fly a plane? - Or to drive a bus? Or to operate a nuclear power plant? Or to play Chopin's etudes on the piano? In each of these examples, a human being operates a complex system of machinery, whether it is a plane, a bus, a nuclear power plant or a piano. What is the common thread running through these abilities?
The study of situational awareness (SA) examines how people do these types of remarkable feats. It is not a bottom-up science though because it relies on finding general principles running through a host of varied human activities. Nevertheless, since it is not constrained by computational details, the study of situational awareness provides a unique opportunity to approach complex tasks of operation from an analytical perspective. In other words, with SA, we get to see how humans observe, recognize and react to complex systems on which they exert some control.
Reconciling this perspective on complexity with complex systems research, it might be possible to further our understanding of complex phenomena if we can probe the anatomical mechanisms by which we, as humans, do it naturally. At this unique intersection of two disciplines, a hybrid approach is needed. So in this work, we propose just such an approach.
In particular, this research proposes a computational approach to the situational awareness (SA) of complex systems. Here we propose to implement certain aspects of situational awareness via a biologically-inspired machine-learning technique called Hierarchical Temporal Memory (HTM). In doing so, we will use either simulated or actual data to create and to test computational implementations of situational awareness. This will be tested in two example contexts, one being more complex than the other. The ultimate goal of this research is to demonstrate a possible approach to analyzing and understanding complex systems. By using HTM and carefully developing techniques to analyze the SA formed from data, it is believed that this goal can be obtained.

Full textAbstract:
Une fusion d'hôpitaux est très souvent à l'origine de transformations importantes. Pourtant, les études menées jusqu'à présent, pour la plupart, ignorent les processus de changement post-fusionnels. Partant de l'observation de trois hôpitaux engagés dans une fusion, cette thèse interroge ces processus de changement, en se demandant pourquoi certains hôpitaux s'engagent dans un processus de fusion. Par ailleurs, elle se pose la question de la transformation post-fusionnelle des lits d'hospitalisation et des filières-réseaux, et qui semblent être l'élément majeur dans les processus de changement des hôpitaux engagés dans de telles opérations. Elle défend l'idée que l'organisation hospitalière est fortement structurée en réseaux, et la fusion consiste à faire bouger ces réseaux. Il s'agit alors de la ré-articulation des trois hôpitaux ensemble et du nouvel hôpital avec son espace sanitaire. Une fois cette ré-articulation entre les différentes entités de nos trois hôpitaux et de leurs partenaires externes stabilisée, l'hôpital devient un espace propice à la mutualisation des moyens, à l'apprentissage et à l'harmonisation. Ceci renforce la stabilité de cette nouvelle structure. L'ensemble de ces processus oriente la fusion vers une fusion intégrative.

Full textAbstract:
The September 11 terrorist attacks pointed out the lack of information sharing between law enforcement agencies as a potential threat to sound law enforcement in the United States. Therefore, many law enforcement agencies as well as the federal government have been initiating information sharing systems among law enforcement agencies to eradicate the information sharing problem. One of the systems established by Homeland Security is the North Central Texas Fusion Center (NCTFC). This study evaluates the NCTFC by utilizing user acceptance methodology. The unified theory of acceptance and the use of technology is used as a theoretical framework for this study. Within the study, user acceptance literature is examined and various models and theories are discussed. Furthermore, a brief information regarding the intelligence work done by law enforcement agencies are explained. In addition to the NCTFC, several major law enforcement information systems are introduced. The data for this study comes from the users of the NCTFC across the north central Texas region. Surveys and interviews are used to triangulate data. It is found in this study that performance expectancy and effort expectancy are important indicators of system use. Furthermore, outreach and needs assessment are important factors in establishing systems. The results of the study offer valuable input for NCTFC administrators, law enforcement officials, and future researchers.

Includes bibliograpical references (leaves 119-134). The most common chromosome abnormalities in live cattle are various Robertsonian translocations (centric fusions). Two hypotheses have been used to explain how monocentric Robersonian translocation chromosomes are generated: either direct formation, or evolution from dicentic chromosomes. Four main cattle procentric Satellite sequences were used as single and two-colour fluorescence in situ hybridization probes for studying the centromere organisation of cattle autosomes and the rearrangement in two cattle Robertsonian translocation chromosomes, the t(1:29) which is monocentric and found in numerous breeds, and the t(14:20) which is dicentric and found in 2 breeds.

Full textAbstract:
Le transport turbulent dans la région centrale est exploré dans un plasma à haut β en mode H hybride du tokamak JET au moyen de simulations linéaires et non-linéaires effectuées avec le code gyrocinétique GKW dans la limite locale. Par rapport aux travaux précédents, l'analyse est étendue à la région ρ > 0.3 et révèle que les Kinetic Ballooning Modes (KBM) y sont linéairement instables, contrairement à la région ρ > 0.3 où les modes Ion Temperature Gradient dominent. Des simulations spécifiques à ρ=0.15 ont permis d'identifier le faible cisaillement magnétique et la haute pression normalisée du plasma, β, comme étant les deux principaux paramètres clefs permettant la déstabilisation des KBM par le relativement faible gradient de pression des ions principaux. Les ions rapides ont un effet légèrement stabilisant lorsqu'ils sont inclus dans les simulations. L'étude est ensuite étendue au régime non-linéaire. La turbulence induite par les KBM génère un flux significatif d'énergie thermique ionique et électronique. De manière inattendue, des modes de micro-déchirement (MTM) linéairement stables sont excités non-linéairement et génèrent un flux non-négligeable d'énergie thermique électronique lié aux fluctuations du champ magnétique. Des modèles quasi-linéaires standards sont ensuite comparés aux résultats non-linéaires. Ces modèles reproduisent raisonnablement bien les flux E x B, mais mésestiment le flux d'énergie thermique électronique résultant de l'excitation non-linéaire des MTMs. Une extension des modèles quasi-linéaire est proposée qui permet de mieux reproduire le flux d'énergie lié aux fluctuations du champ magnétique<br>Turbulent transport is investigated in the central region of the high-β JET hybrid H-mode discharge 75225 by means of linear and non-linear gyro-kinetic (GK) simulations using the GK code GKW in the local approximation limit. Compared to previous work, the analysis is extended towards the magnetic axis, ρ > 0.3, where the turbulence characteristics remain an open question. In contrast to the region ρ > 0.3 where Ion Temperature Gradient modes are the most unstable modes, the linear stability analysis indicates that Kinetic Ballooning Modes (KBM) dominate in the central region. A dedicated analysis performed at ρ=0.15 reveals that the main parameters responsible for the destabilisation of KBMs in these hybrid H-modes are the high β and low magnetic shear values. The KBMs are driven by the main ion pressure gradient with little influence of the electron temperature gradient. Including fast-ions as a kinetic species in the simulations has a slight stabilising effect. The study is then extended to the non-linear regime. It is found that the turbulence induced by these KBMs drives a significant ion and electron heat flux. Interestingly, linearly stable micro-tearing-modes (MTM) are excited non-linearly and drive a sizeable magnetic flutter electron heat flux. Standard quasi-linear models are compared to the non-linear results. The standard reduced quasi-linear models work reasonably well for the E x B fluxes, but fail to capture magnetic flutter contribution to the electron heat flux induced by the non-linear excitation of the MTMs. An extension of the quasi-linear models is proposed allowing to better capturing the magnetic flutter flux

Find full textAbstract:
This project, realised in collaboration with ENEA Frascati, was aimed at the calculation of the power losses in electrodynamic transient in the Central Solenoid of the Divertor Tokamak Torus (DTT). The DTT machine is a fusion Tokamak machine being built by ENEA, in the location of Frascati, Roma.
The power losses are a fundamental parameter for the realisation and the design of the machine.
One of the constituents of the DTT is an articulated system of magnets, made up by different components; among these, the most important is the Central Solenoid, whose aim is also to
induce a strong current in the Plasma, which generates magnetic field lines in the poloidal direction, which are very important to confine the Plasma itself.
The project consisted, firstly, on the creation and validation of the model, by carrying out the calculation of the magnetic field on the axis of the Central Solenoid of the Divertor Tokamak Torus; first, only the contribution of the Central Solenoid was considered, then also, the Poloidal system was taken into account and to conclude, also the Plasma contribution was added. This omputation was performed in an analytical and in a numerical way: the results given by these two methodologies were compared and the trends totally coincided. Also, the values obtained were completely confirmed by the ones computed by ENEA.
Once the model was validated, we proceeded by performing the calculation of the losses in electrodynamic transient: an analytical model which calculates the coupling and hysteresis losses
in the Central Solenoid of the Divertor Tokamak Torus was developed. Moreover, the trends of these losses throughout the time and their distributions in the Central Solenoid’s modules
were found.

Lopez, Franco Ignacio. "Autonomous pseudomonoids." Thesis, University of Cambridge, 2009. https://www.repository.cam.ac.uk/handle/1810/219201.
Full textAbstract:
In this dissertation we generalise the basic theory of Hopf algebras to the context of autonomous pseudomonoids in monoidal bicategories. Autonomous pseudomonoids were introduced in [13] as generalisations of both autonomous monoidal categories and Hopf algebras. Much of the theory of autonomous pseudomonoids developed in [13] was inspired by the example of autonomous (pro)monoidal enriched categories. The present thesis aims to further develop the theory with results inspired by Hopf algebra theory instead. We study three important results in Hopf algebra theory: the so-called 'fundamental theorem of Hopf modules', the 'Drinfel'd quantum double' and its relation with the centre of monoidal categories, and 'Radford's formula'. The basic result of this work is a general fundamental theorem of Hopf modules that establishes conditions equivalent to the existence of a left dualization. With this result as a base, we are able to construct the centre (defined in [83]) and the lax centre of an autonomous pseudomonoid as an Eilenberg-Moore construction for certain monad. As an application we show that the Drinfel'd double of a finite-dimensional Hopf algebra is equivalent to the centre of the associated pseudomonoid. The next piece of theory we develop is a general Radford's formula for autonomous map pseudomonoids formula in the case of a (coquasi) Hopf algebra. We also introduce 'unimodular' autonomous pseudomonoids. In the last part of the dissertation we apply the general theory to enriched categories with a (chosen) class of (co)limits, with emphasis in the case of finite (co)limits. We construct tensor products of such categories by means of pseudo-commutative enriched monads (a slight generalisation of the pseudo-commutative 2-monads of [37], and showing that lax-idempotent 2-monads are pseudo-commutative. Finally we apply the general theory developed for pseudomonoids to deduce the main results of [27].

Le caractère ponctuel des datations (point de ~2 µm de diamètre) permet de mettre en évidence plusieurs événements enregistrés sur un grain unique et éviter les problèmes de mélange rencontrés avec d'autres méthodes de datation. Trois événements thermiques sont identifiés : un évènement entre 385 et 375 Ma, un autre autour de 330 et 325 Ma et un dernier vers 310 et 290 Ma. Ils sont contrôlés par l'épaississement et le des-épaississement crustal et des injections asthénosphériques.

Full textAbstract:
Mestrado em Geomateriais e Recursos Geológicos<br>A área de estudo localiza-se no Domínio Ceará Central (NE do Brasil). É constituída, em grande parte da sua extensão, por rochas orto- e para-derivadas de idades compreendidas entre o Paleoproterozóico e o Neoproterozóico, intensamente afetadas por metamorfismo regional e migmatização durante o ciclo Orogénico Brasiliano/Pan-Africano (~600 M.a).
Na parte ocidental da região, o Complexo Gnáissico-Migmatítico (CGM) contata com um maciço granítico de tipo S (Granito de Banabuiú) de grandes dimensões e com um pequeno corpo granodiorítico (Fácies Novo Encanto) intruídos nas fases finais da Orogenia Brasiliana.
As evidências de campo e de petrografia revelam que os ortognaisses e paragnaisses presentes no substrato da região sofreram fusão parcial durante a terceira fase de deformação brasiliana (D3), num regime tectónico transcorrente ligado à atuação da zona de cisalhamento esquerda de Orós.
No entanto, os abundantes volumes de leucossomas intercalados nestas rochas parecem ter sido essencialmente gerados em níveis estruturais algo mais profundos e injetados nestes terrenos sob a forma de veios leucocráticos, levando a interpretar o CGM como um complexo anatético de injeção.
Em fases mais avançadas do evento metamórfico de alto grau, a produção de maiores quantidades de “melt” em profundidade terá estado na origem da formação dos diatexitos e do próprio granito de duas micas de Banabuiú. A ocorrência do granodiorito biotítico de Novo Encanto em íntima associação espacial com o batólito granítico de Banabuiú sugere ainda que a fusão parcial em grande escala de materiais da crusta continental superior foi acompanhada pela intrusão de pequenos volumes de magmas máficos de proveniência mantélica e/ou infracrustal.
Os dados geoquímicos e isotópicos (Sr-Nd) mostram que os veios leucocráticos, os diatexitos e o granito de Banabuíu partilharam a mesma fonte e podem ter derivado da fusão parcial de protólitos com composições semelhantes às dos paragnaisses encaixantes. A sua evolução parece ter sido controlada por processos de acumulação, cristalização fracionada e contaminação, em graus variáveis, com o resíduo sólido.<br>The studied area is located in the Ceará Central Domain (NE Brazil). It is largely composed by Paleoproterozoic-Neoproterozoic igneous- and sedimentary-derived rocks, intensely affected by high-grade regional metamorphism during the Brazilian Orogeny (~600 Ma).
In the western portion of the region, the Gneiss-Migmatitic Complex (GMC) is intruded by an S-type granite (Banabuiú Granite) and a small body of a biotite granodiorite (Novo Encanto facies), both emplaced in the final stages of the Brazilian Orogeny.
Field and petrographic evidence reveal that the GMC orthogneisses and paragneisses were both affected by partial melting during the third Brazilian deformation phase (D3), in a transcurrent tectonic regime related to the sinistral Orós shear zone.
However, the huge amounts of leucosomes associated with the orthogneisses and paragneisses appear to have been mostly generated at slightly deeper structural levels and injected in these terrains as leucocratic veins. As such, the GCM is interpreted here as an anatectic injection complex.
During the last stages of the high-grade metamorphic event, the production of larger amounts of melt at depth was responsible for the formation of the diatexites and the Banabuiú two-mica granite. The occurrence of the Novo Encanto biotite granodiorite in close association with the Banabuiú granite suggests that the partial melting episode was accompanied by the intrusion of small volumes of mafic magmas of still deeper origin (mantle / lower crust).
The geochemical and Sr-Nd isotopic data show that the leucocratic veins, the diatexites and the Banabuiú two-mica granite shared the same crustal source and could have been derived from partial melting of metasedimentary protoliths similar to the outcropping paragneisses. Their evolution appears to have been controlled by processes of crystal accumulation, fractional crystallization and variable degrees of contamination with the solid residue.

Full textAbstract:
The working situation of fighter pilots is often very challenging. The pilots are requested to perform their tasks and make decisions in situations characterised by time-pressure, huge amounts of data and high workload, knowing that wrong decisions might result in fatal consequences. To aid the pilots, several automatic support systems have been implemented in modern fighter aircraft and will continue to be implemented in pace with technological advancements and new demands posed on the pilots. For example, innovations within the information fusion (IF) domain have made it possible to fuse large amounts of data, stemming from different sensors, databases etc., to create a better foundation for making decisions and act than would have been possible if the information sources had been used separately. However, there are both positive and negative effects of automation, such as decreased workload and improved situation awareness on the one hand, but skill degradation and complacent behaviour on the other. To avoid the possible negative consequences of automation, while at the same time ameliorating the positive ones, a human-centred automation (HCA) approach to system design has been proposed as a way of optimizing the collaboration between the human and the machine. As a design approach, HCA stresses the importance of a cooperative human-machine relationship, where the operator is kept in the automation loop. However, how to introduce HCA within the fighter aircraft domain as well as its implications for the interface and automation design of support systems within the field has not been investigated. This thesis investigates the implications of introducing HCA into the fighter aircraft domain. Through literature surveys and empirical investigations, general and domain specific HCA guidelines have been identified. These advocate, for example, that an indication of the reliability of the information and the recommendations provided by the different aircraft support systems must be given as well as that support for appropriate updates of the pilots’ individual and team awareness of the situation must be provided. A demonstrator, mirroring some of the identified guidelines, has been implemented and used to evaluate the guidelines together with system developers within the domain. The evaluation indicated that system developers of modern fighter aircraft implicitly incorporate many of the identified HCA guidelines when designing. However, the evaluation further revealed that to explicitly incorporate these guidelines into the development approach, preferably through the development of a domain specific style guide, would aid the system developers design automated support systems that provide appropriate support for the pilots. The results presented in this thesis are expected to aid developers of modern fighter aircraft support systems by incorporating HCA into the traditional simulator-based design (SBD) approach. This approach is frequently used within the field and stresses early and frequent user-involvement when designing, in which complementary HCA evaluations could be performed to further improve the support systems implemented from an automation perspective. Furthermore, it is expected that the results presented in this thesis will contribute to the research regarding how to incorporate the human operator in the information fusion processes, which has been recognised as a research gap within the IF field. Thus, a further contribution of this thesis is the suggestion of how the HCA development approach could be of aid when improving the interaction between the operator and the automated fusion system.<br>Arbetssituationen för stridspiloter är ofta mycket utmanande. Piloterna måste utföra sina uppgifter och fatta beslut i stressiga situationer med stora informationsmängder och hög arbetsbörda, samtidigt som val av fel beslut kan leda till allvarliga konsekvenser. För att hjälpa piloterna har flera automatiska stödsystem implementerats i moderna stridsflygplan. Denna trend kommer att fortsätta i takt med nya tekniska framgångar och nya krav som ställs på piloterna. Forskning inom informationsfusion (IF) har bland annat gjort det möjligt att fusionera stora mängder data som härstammar från olika sensorer, databaser m.m. för att på så sätt skapa en bättre grund för att fatta beslut och agera än vad som hade varit möjligt om informationskällorna hade använts separat. Dock har både positiva och negativa effekter av automatisering rapporterats, såsom minskad arbetsbörda och förbättrad situationsuppfattning men även försämrad pilotprestation till följd av att de automatiska systemens prestanda inte övervakas. För att undvika negativa effekter av automation samtidigt som de positiva effekterna stärks har den så kallade människo centrerade automationen (HCA) lyfts fram som en möjlig väg att designa system där samverkan mellan automationen och den mänskliga operatören optimeras. Som en designapproach fokuserar HCA på viken av en samverkande människamaskin relation, där operatören hålls kvar i automatiseringsloopen. Men hur HCA kan introduceras inom stridsflygdomänen och dess implikationer för gränssnitts- och automationsdesign av stödsystem inom domänen har inte undersökts. Denna licentiatavhandling undersöker möjliga implikationer av att introducera HCA inom stridsflygdomänen. Genom litteraturundersökningar och empiriska studier har generalla och domänspecifika HCA riktlinjer identifierats, såsom att piloterna måste erbjudas en indikation angående tillförlitligheten hos den information och de rekommendationer som de olika implementerade stödsystemen i flygplanet har genererat, samt att stöd för att uppdatera piloternas individuella och gemensamma uppfattning av situationen måste ges. En demonstrator, som återspeglar några av de identifierade HCA riktlinjerna, har implementerats och använts för att utvärdera riktlinjerna tillsammans med systemutvecklare inom domänen. Denna utvärdering påvisade att systemutvecklare inom stridsflygdomänen implicit använder sig av många av de identifierade HCA riktlinjerna under designprocessen, men att explicit inkludera dessa i en domänspecifik design guide skulle kunna hjälpa dem att designa automatiska system som erbjuder lämpligt stöd för piloterna. De resultat som presenteras i denna licentiatavhandling förväntas kunna hjälpa utvecklare av moderna stridsflygsystem genom att inkludera HCA i den traditionella simulator-baserade designapproachen (SBD). Denna approach används flitigt inom området och fokuserar på tidigt och återkommande användardeltagande vid designarbetet, där komplementära HCA utvärderingar skulle kunna genomföras för att förbättra de stödsystem som implementeras från ett automationsperspektiv. Det förväntas även att de resultat som presenteras i denna avhandling kommer att bidra till forskningen kring hur operatörer kan påverka fusionsprocessen, vilket har identifierats som ett område där mer forskning behövs inom IF området. Ytterligare ett bidrag av denna avhandling är därför det förslag som ges på hur HCA utvecklingsprocessen skulle kunna användas för att förbättra interaktionen mellan operatören och det automatiska fusionssystemet.

Full textAbstract:
This dissertation examines a bank’s right to unilaterally terminate its contractual relationship with a customer on the basis of reputational risk. The law of contract allows a bank to terminate the bank-customer agreement when the customer is in serious breach of the contract. Over the years, however, a pattern has started to develop by which a bank can unilaterally terminate the bank-customer relationship of high-risk customers based on reputational risk. Banks are reluctant to facilitate the transactions of individuals surrounded by negative publicity, due to fears of how the bank’s investors, customers or counterparts might perceive the bank.
Compliance with anti-money laundering (AML) and counter financing of terrorism (CFT) requirements, as set out by both domestic and foreign legislation, results in higher costs for the bank. As such, the profitability of a particular bank-customer relationship may ultimately decline to such an extent that the bank rather decides to make an appropriate business decision by terminating the relationship.
Correspondent banking relationships are agreements in terms of which one bank will provide services for another in jurisdictions where the first bank lacks a physical presence. As such, whenever there is a perception that a local bank does not comply with the relevant AML/CFT laws as set out by its domestic legislation, the correspondent bank might decide to terminate its relationship with the local bank, leaving the latter financially excluded from the correspondent banking market. Such a situation would hinder the growth of the South African economy and may also cause a systemic event in the financial industry.
Adequate customer due diligence (CDD) measures assist a bank in formulating a clear understanding of the business of its customers. The information obtained through CDD may also assist the bank in determining the reputation of a particular customer. This information can also assist law enforcement in combatting financial crimes. In this regard, it is recommended that a bank should be able to trace the information that was shared with Financial Intelligence Units (FIUs) and law enforcement agencies, so that the bank may reasonably determine the level of reputational risk involved in the relationship.<br>Mini Dissertation (LLM)--University of Pretoria, 2020.<br>Mercantile Law<br>LLM<br>Unrestricted

A crescente evidência de que a maior parte das galáxias hospedam buracos negros supermassivos (SMBHs) em seu centro e a aceitação geral de um paradigma hierárquico de formação galáctica indica que galáxias e SMBHs devem ter evoluído concorrentemente. Este cenário tem levado a uma intensa busca por subprodutos desta evolução, entre eles o recuo gravitacional, um fenômeno que ocorre durante a fusão de SMBHs, e que pode gerar uma explosão observável de ondas gravitacionais, com a subsequente expulsão de um dos SMBHs do centro galáctico. Um dos candidatos mais interessantes apresentando a \assinatura" de um recuo gravitacional é o rádio-quasar J133658.3-295105, um objeto a distância de NGC 5236 que aparece projetado sobre o corpo desta galáxia em um sugestivo alinhamento com outras fontes de rádio e o núcleo óptico da galáxia, que também aparece deslocado em relação ao centro cinemático de NGC 5236. Neste trabalho nós estudamos as circunstâncias no qual o rádio-quasar teria sido ejetado da região central de NGC 5236. Nós analisamos diferentes tipos de colisões de SMBHs binários e triplos por meio de simulações numéricas usando uma aproximação Pós-Newtoniana de ordem 7=2 (~1=c7). Para isso, nós desenvolvemos um código de Ncorpos especialmente construído para integrar numericamente as equações de movimento Pós-Newtonianas. Experimentos numéricos demonstram que o código é robusto o suficiente para tratar praticamente qualquer razão de massas entre partículas. Nós mostramos que, dentro da atual aproximação Pós-Newtoniana, o cenário com três SMBHs _e o mais adequado para explicar a ejeção de J133658.3-295105 e, simultaneamente, provocar o deslocamento do núcleo óptico de NGC 5236. Nossos modelos mostram que o deslocamento do núcleo óptico pode estender-se por uma distância radial de ~ 30 - 200 pc sobre uma escala de tempo de ~ _107 anos, em razoável acordo com o valor observado em NGC 5236 (~ 60 pc). Nós mostramos também que o deslocamento do núcleo óptico só pode ser explicado em um cenário de recuo gravitacional se a velocidade de recuo do SMBH for até cerca de ~ 1:5 vezes a dispersão de velocidades das estrelas no centro da galáxia. Os diferentes conjuntos de simulações permite-nos ainda distinguir entre dois tipos de recuo gravitacional em sistemas com SMBHs triplos, o primeiro ocorrendo por uma troca energética entre um dos SMBHs e a binária recém formada durante interação com os outros dois SMBHs, e o segundo ocorrendo por consequência da emissão anisotrópica de ondas gravitacionais durante a coalescência dos SMBHs. Nossas simulações mostram que o primeiro tipo de recuo gravitacional deve ocorrer muito antes que o par de SMBHs mais fortemente ligado possa atingir o regime de radiação. As limitações do nosso modelo, contudo, não permite-nos afirmar qual deles ocorreu em NGC 5236, embora o primeiro seja mais provável.<br>The growing evidence that most galaxies host supermassive black holes (SMBHs) at its center, and general acceptance of a paradigm of hierarchical galaxy formation states that galaxies and SMBHs must have evolved concurrently. This scenario has led to an intense search by-products of this evolution, including the gravitational recoil, a phenomenon that occurs during the merger of SMBHs, which can generate an observable outburst of gravitational waves and the subsequent expulsion of one of the SMBHs of galaxy center. One of the most interesting candidates showing the \signature" of a gravitational recoil is the radio-quasar J133658.3-295105, an object at distance of NGC 5236 that appears projected onto the body of this galaxy in a suggestive alignment with other sources of radio and optical nucleus of galaxy, which also appears displaced from the kinematic center of NGC 5236. In this work we study the circumstances in which the radio-quasar would have been ejected from the central region of NGC 5236. We analyze di erent types of collisions of binary and triple SMBHs by numerical simulations using a Post-Newtonian approximation of order 7=2 ( ~1/c7). For this, we developed a N-body code specially built for numerically integrate the Post-Newtonian equations of motion. Numerical experiments show that the code is robust enough to handle virtually any mass ratio between particles. We show that within the current Post-Newtonian approximation, the scenario with three SMBHs is best suited to explain the ejection of J133658.3-295105, while causing the displacement of the optical nucleus of NGC 5236. Our models show that the displacement of the optical nucleus can extend over a radial distance of ~ 30 - 200 pc on a timescale of ~ 2x107 years, in reasonable agreement with the observed value in NGC 5236 ( 60 pc). We also show that the displacement of the optical nucleus can only be explained in a scenario of gravitational recoil if the velocity of recoil of the SMBH is up to about 1:5 times the velocity dispersion of stars in the galactic center. The di erent sets of simulations allows us to distinguish between two types of gravitational recoil on systems with SMBHs triple, the rst occurring by an energy exchange between one of the SMBHs and the newly formed binary during interaction with the other two SMBHs, and the second occurring as a consequence the anisotropic emission of gravitational waves during the coalescence of SMBHs. Our simulations show that the rst type of gravitational recoil should occur long before the pair of SMBHs more tightly bound to achieve the regime of radiation. The limitations of our model, however, does not allow us to say which of them occurred in NGC 5236, although the former is more likely.

Full textAbstract:
La serotonine, (5-hydroxytryptamine, 5-ht) est une amine biogene qui agit comme un neurotransmetteur au niveau du systeme nerveux central, ou elle est largement distribuee. Elle intervient dans de nombreuses fonctions physiologiques et cerebrales, par l'intermediaire de plusieurs recepteurs differents. Parmi les recepteurs serotoninergiques, le sous-type 5-ht#1#a a ete particulierement etudie, depuis plus d'une decennie, d'une part parce que l'on dispose d'un agoniste hautement specifique, le 8-oh-dpat, et d'autre part a cause de son implication dans la physiopathologie de l'anxiete et de la depression. Les etudes autoradiographiques ont permis de localiser les sites de liaison des recepteurs 5-ht#1#a a l'echelle anatomique. Ils sont concentres dans les structures limbiques comme le septum, l'hippocampe, le cortex, l'amygdale. Les noyaux du raphe sont egalement riches en recepteurs 5-ht#1#a (autorecepteurs somato-dendritiques). Grace a des anticorps specifiques anti-peptide et anti-proteine de fusion diriges contre la troisieme boucle cytoplasmique de la proteine, nous avons etudie la localisation des recepteurs 5-ht#1#a a l'echelle structurale et ultrastructurale par immunohisto- et cytochimie. En microscopie photonique, la repartition regionale de l'immunoreactivite est identique a celle des sites de liaison : les recepteurs sont abondants dans le systeme limbique et les noyaux du raphe. Les aires extra-pyramidales, en revanche, sont pauvres en recepteurs. L'immunoreactivite est localisee sur des corps cellulaires neuronaux (par exemple dans les noyaux du raphe et le complexe septal) et probablement sur des dendrites. Dans le cervelet du jeune rat, l'immunomarquage est localise dans les cellules de purkinje. La visualisation en microscopie electronique a confirme la localisation somato-dendritique des recepteurs dans le noyau raphe dorsal et le complexe septal. Dans l'hippocampe, l'immunoreactivite est exclusivement dendritique. Les cellules gliales ne sont pas marquees. L'immunomarquage est plus intense au niveau de la membrane plasmique, et est associe ou non a des differenciations synaptiques. Cette localisation non-jonctionnelle est en accord avec l'hypothese selon laquelle la 5-ht peut agir a distance de son lieu de liberation (transmission volumique). Enfin, l'identification des cellules cibles portant le recepteur 5-ht#1#a a ete effectuee partiellement dans le complexe septal. Des experiences de doubles marquages immunocytochimiques en microscopie photonique et electronique dans cette region ont montre que le recepteur 5-ht#1#a est exprime par une partie des neurones cholinergiques. La serotonine pourrait ainsi moduler l'activite de ces neurones, qui se projettent majoritairement vers l'hippocampe.

Full textAbstract:
Le dôme du Velay, occupant la partie orientale du Massif Central Français, est un dôme anatectique caractérisé par la succession de deux stades de fusion (M3 et Mv). Les relations entre déformation D3 et fusion M3 montrent que la fusion est précoce par rapport au développement des structures. La déformation engendre un ensemble de plis dissymétriques, à déversement général vers le nord. Les assemblages minéralogiques sont à biotite-sillimanite-quartz sans cordiérite, suggérant que la fusion n'a pas impliqué la biotite (T < 750°C, P > 5 kbar). Le collectage des mobilisats a été contrôlé par la tectonique et s'est produit à petite échelle sans transfert important de matière. Des plans à sillimanite fini-D3 se développent par lessivage acide en régime de déformation. Ils sont l'indice d'une chute de la température entre M3 et les événements ultérieurs, la partie supérieure de l'édifice anatectique repassant en conditions subsolidus. La phase Mv se caractérise par des assemblages cordiérite-orthose et grenat-orthose, correspondant à un accroissement sensible de la température (750 < T < 850°C, P = 4-5 kbar). Dans les migmatites, la cordiérite se développe de façon mimétique sur les mélanosomes M3. Elle atteint son développement maximal dans les granites vellaves (nodules, dendrites, cristaux isoles automorphes). La phase d'anatexie Mv reconnue comme la phase d'individualisation du dôme vellave, est régionalement considérée comme extensive (grandes failles de détachements fini-hercyniennes). Néanmoins, dans la bordure sud du dôme, les structures distensives syn-Mv restent d'importance limitée par rapport aux structures compressives méridiennes ubiquistes, interprétées comme le résultat d'un déversement du dôme du Velay vers le sud. Des cisaillements synmigmatitiques tardifs montrent un collectage, à petite échelle, de liquide anatectique à biotite. Ils sont liés à la retombée thermique du domaine vellave. Ceci suggère que les orthogneiss était encore partiellement fondus, mais avec une proportion de liquide faible, inferieure au seuil rhéologiquement critique. La baisse des températures entre M3 et Mv permet de dissocier les deux stades de migmatisation. La phase 3 marque la fin de l'épisode compressif lié à la mise en place des nappes et correspond au réchauffement d'une pile crustale épaissie. La phase Mv correspond à un autre régime de contraintes et à un autre régime thermique dont la dynamique est à rechercher dans l'effondrement gravitaire post-collision et dans une anomalie thermique liée à l'injection de magmas basiques mantelliques dont les vaugnerites seraient les témoins

Full textAbstract:
Les granites à métaux rares sont issus de la cristallisation de magmas très évolués enrichis en volatiles et fondants (F, Li, P, B) et en métaux tels que Sn, Nb, Ta et W. Dans la chaîne Varisque d’Europe de l’Ouest, ils résultent d’un magmatisme tardi-orogénique spécifique. Depuis les années 60, de nombreuses études se sont intéressées à la signature géochimique de ces granites et différents modèles de genèse ont pu être proposés. Malgré cela, plusieurs questions subsistent; le contexte et les mécanismes de mise en place de ces granites particuliers ne sont que rarement abordés. Afin d’avoir une vision complète des processus et mécanismes responsables de (i) la genèse des magmas à métaux rares, (ii) la géométrie et la mise en place de ces granites, (iii) leur signature géochimique et leur enrichissement en métaux, une étude multi-approches et multi-échelles a été menée sur l’exemple du granite à métaux rares d’Argemela (Zone Centro-Ibérique, Portugal). Elle a été complétée par une étude expérimentale portant sur la genèse des magmas. Les résultats de l’étude structurale montrent que l’intrusion d’Argemela se met en place dans un contexte particulier. Plusieurs critères suggèrent une remontée verticale rapide et chenalisée du magma jusqu’à un niveau très superficiel, subvolcanique. L’étude pétrologique et géochimique du granite et des minéralisations associées a permis de mettre en évidence les évènements clés et les processus mis en jeu durant la transition magmatique-hydrothermale. Ceci a également permis d’appréhender les processus de concentration/transport des métaux et les mécanismes de dépôt des minéralisations. L’étude expérimentale indique qu’un seul stade de fusion partielle à faible taux ne permet pas de générer des magmas suffisamment enrichis en métaux. Cependant, un mécanisme de refusion de restites enrichies, qui reste encore à tester, pourrait produire les concentrations en métaux requises. Enfin, cette étude démontre la nécessité de combiner les approches car l’ensemble des processus sont interdépendants dans ce type de systèmes minéralisés<br>Rare metal granites result from the crystallization of highly evolved magmas enriched in volatiles and fluxing elements (F, Li, P, B) and in metals such as Sn, Nb, Ta and W. In the Western Europe Variscan belt, these granites are attributed to a late orogenic episode of rare metal magmatism. Since the 60’s, numerous studies have focused on the specific geochemical signature of rare metal granites and several models have been proposed for their genesis. However, several questions remain and, in particular, the context and mechanisms of magma emplacement have been only rarely addressed. In order to build a comprehensive understanding of magmatic, hydrothermal and tectonic processes and mechanisms responsible for (i) rare metal magma generation, (ii) magma emplacement and geometry, (iii) specific geochemical signature and metal enrichment, a multi-approach and multi-scale study has been performed on the example of the rare metal granite of Argemela (Central Iberian Zone, Portugal). It has been complemented by an experimental study on the genesis of rare metal magmas. Results of the structural analysis highlighted the special structural context of emplacement of the Argemela intrusion. Several criteria suggest a fast vertical and channelled magma ascent up to shallow subvolcanic levels. The petrological and geochemical study of the granite and related mineralization allow the identification of key events and processes involved during the magmatic-hydrothermal transition. Mechanisms of concentration/transportation and deposition of metals have been also specified. The experimental study indicates that a single step low degree partial melting is not efficient enough to produce rare metal magmas, since most are sequestered into the restite. However, remelting of enriched restitic assemblages, a mechanism which remains to be tested, could well produce the required rare metal concentrations. Finally, this study demonstrates the necessity to combine several approaches, since processes and mechanisms are interrelated in these mineralized systems

Les variations cristallochimiques des minéraux essentiels viennent conforter les discriminations établies par les études pétrographiques et géochimiques. La géochimie des éléments en trace montre que la fusion partielle est à l'origine de ces facies. Deux matériaux sources sont impliqués dans la génèse des facies à biotite et cordiérite ; l'ensemble des leucogranites (avec ou sans sillimanite) relève, par contre, de la fusion d'un matériau source unique. La diversité constatée, pétrographiquement et chimiquement, au sein de ce dernier ensemble est due à une ségrégation plus ou moins complète des phases résiduelles

Au jurassique, le Haut Atlas a été le siège d'une grande manifestation magmatique de nature alcaline. Elle a eu lieu en régime intraplaque contemporain à l'ouverture de l'Atlantique.

L'étude pétrographique, minéralogique et géochimique des deux intrusions a mis en évidence trois groupes de roches: des facies gabbroïques, avec une faible variation minéralogique, représentés par des melatroctolites, des gabbros à olivine, des gabbros à biotite, des leucogabbros et des gabbros différenciés. Des facies dioritiques. Des facies synetiques albitisés, ou la phase minérale ferromagnésienne est presque inexistante. La caractérisation géochimique a permis de conclure que: la différenciation des roches étudiées est contrôlée par le phénomène de la cristallisation fractionnée. L'olivine, le plagioclase, le clinopyroxène, l'ammphibole et la biotite ont probablement joue le rôle le plus important. Les gabbros et les diorites constituent une évolution continue, alors que les syénites sont issues de la différenciation de magmas moins évolués qui ont donne les cumulats gabbroïques. Les roches basiques des deux intrusions résulteraient de la fusion faible d'un manteau appauvri en éléments immobiles, enrichi en éléments mobiles par des fluides d'origine profonde. Les deux intrusions se sont mises en place à la faveur d'anciennes fractures profondes réactivées

Mestrado em Administração e Gestão Pública<br>Da Reforma de Gonçalves Ferreira, que constituiu a base para o atual Sistema, à criação da Lei n.º27/2002, de 8 de novembro, que lança as bases para a criação dos Centros Hospitalares, o Sistema de Saúde Português sofreu várias transformações. Na base destas alterações, porém, está sempre patente a procura de uma melhoria da qualidade dos cuidados de saúde, uma maior eficiência dos serviços e ainda a satisfação dos utentes. Uma oferta de cuidados gerais a todos os cidadãos foi também uma preocupação existente nestas reformas. Sabe-se, no entanto, que os Hospitais revelam uma grande complexidade na sua organização e gestão, dadas as suas características intrínsecas e o domínio onde atuam. Os serviços que oferecem e os diferentes problemas que surgem todos os dias dificultam o trabalho dos gestores. É, também, sobre o serviço de urgência que têm recaído as preocupações dos vários gestores, tendo-se este transformado na primeira escolha dos utentes, tornando os serviços menos eficientes e desajustando a dinâmica dos hospitais. Realizado em contexto de estágio, o trabalho desenvolvido teve como duplo propósito: por um lado, perceber o impacto que uma das reformas do sistema de saúde deste século – a fusão hospitalar e a consequente criação de Centros Hospitalares – tem produzido, designadamente no que respeita aos tempos que decorrem desde que o utente sente uma necessidade de utilizar um serviço de urgência até ao primeiro atendimento médico; por outro lado, compreender a dinâmica de fluxos dos utentes do Centro Hospitalar do Baixo Vouga, E.P.E. e mais particularmente os Serviços de Urgência do Hospital Distrital de Águeda e do Hospital Infante D.Pedro em Aveiro. O estudo mostra que a fusão não trouxe uma melhoria no atendimento ao utente em situação de urgência, no que ao acesso diz respeito. No entanto, há algumas medidas que podem ser tomadas para reduzir os tempos de espera e aumentar a qualidade do serviço de urgência do Centro Hospitalar do Baixo Vouga,
nomeadamente a criação de fluxogramas como base de apoio à tomada de decisões.<br>Since the Gonçalves Ferreira’s overhaul, which was the basis of the current System, up until the creation of the Law n.º27/2002, of november 8th, that launches the basis to the creation of the Hospital Centres, the Portuguese Healthcare System underwent several transformations. On the basis of these amendments, however, it is always clear the improvement of the healthcare quality, a greater efficiency of the sevices and still the users’ satisfaction. The care offer to all citizens was also the concern existing in all of the overhauls. It is known, however, that the Hospitals show a big complexity in its organisation and management given its characteristics and the area where they operate. The services that are offered and the various problems that present themselves every day make the managers’ work difficult. It is, also, on the Emergency Department that the managers’ concerns have fallen, but the latter has become the first choice of the users, becoming the services less eficient and misfits the hospitals’ dynamics. Carried out in an internship context, the work developed had as a double purpose: on one hand, to understand the impact that one of the Healthcare Systems’ overhauls of this century – the hospitalar fusion and the consequente creation of Hospital Centres – has produced, namely in respect of the time that passes since the user feels the need to utilize an emergency service up until the first medical assistance; on the other hand, to understand the flow dynamics of the users of the Centro Hospitalar do Baixo Vouga, E.P.E. and particularly the Emergency Services of the Hospital Distrital de Águeda and the Hospital Infante D.Pedro in Aveiro. The study shows that the fusion did not bring improvement to the users’ assistance in an emergency situation, concerning the access. However, there are a few measures that can be adopted to reduce the waiting times and increase the emergency service’s quality of the Centro Hospitalar do Baixo Vouga, E.P.E,
namely the creation of flowcharts as a support system to the decision making
process.

Full textAbstract:
It is critical to provide an efficient and accurate information system in the post-disaster phase for individuals' in order to access and obtain the necessary resources in a timely manner; but current map based post-disaster management systems provide all emergency resource lists without filtering them which usually leads to high levels of energy consumed in calculation. Also an effective post-disaster management system (PDMS) will result in distribution of all emergency resources such as, hospital, storage and transportation much more reasonably and be more beneficial to the individuals in the post disaster period. In this Dissertation, firstly, semi-supervised learning (SSL) based graph systems was constructed for PDMS. A Graph-based PDMS' resource map was converted to a directed graph that presented by adjacent matrix and then the decision information will be conducted from the PDMS by two ways, one is clustering operation, and another is graph-based semi-supervised optimization process. In this study, PDMS was applied for emergency resource distribution in post-disaster (responses phase), a path optimization algorithm based ant colony optimization (ACO) was used for minimizing the cost in post-disaster, simulation results show the effectiveness of the proposed methodology. This analysis was done by comparing it with clustering based algorithms under improvement ACO of tour improvement algorithm (TIA) and Min-Max Ant System (MMAS) and the results also show that the SSL based graph will be more effective for calculating the optimization path in PDMS.
This research improved the map by combining the disaster map with the initial GIS based map which located the target area considering the influence of disaster. First, all initial map and disaster map will be under Gaussian transformation while we acquired the histogram of all map pictures. And then all pictures will be under discrete wavelet transform (DWT), a Gaussian fusion algorithm was applied in the DWT pictures. Second, inverse DWT (iDWT) was applied to generate a new map for a post-disaster management system. Finally, simulation works were proposed and the results showed the effectiveness of the proposed method by comparing it to other fusion algorithms, such as mean-mean fusion and max-UD fusion through the evaluation indices including entropy, spatial frequency (SF) and image quality index (IQI). Fuzzy set model were proposed to improve the presentation capacity of nodes in this GIS based PDMS.<br>Ph.D.<br>Doctorate<br>Industrial Engineering and Management Systems<br>Engineering and Computer Science<br>Industrial Engineering

L'objet de ce travail est de présenter une partie des travaux entrepris au laboratoire CELIA (CEA, CNRS, Université Bordeaux I) dans le domaine de la modélisation numérique des écoulements fortement compressibles. Cette activité au sein de l'équipe Interaction-Fusion par Confinement Inertiel-Astrophysique, a eu pour objectif principal la mise au point et le développement de schémas numériques robustes dédiés à la simulation numérique des plasmas à haute densité d'énergie appliquée à la production d'énergie par fusion. Ces travaux se sont concrétisés par l'écriture du code CHIC (Code d'Hydrodynamique et d'Implosion du CELIA), logiciel permettant de concevoir et de restituer des expériences dans le domaine de la Fusion par Confinement Inertiel (FCI). Le modèle théorique numérique décrivant l'implosion d'une cible laser est un système d'équations aux dérivées partielles au centre duquel on trouve les équations d'Euler écrites dans le formalisme lagrangien, couplées à des équations de diffusion non linéaires modélisant le transport de l'énergie par les électrons et les photons. Dans cet exposé, après un bref rappel du contexte physique, nous décrirons les deux méthodes originales qui constituent l'ossature numérique du code CHIC. Il s'agit de deux schémas numériques d'ordre élevé du type volumes finis dédiés respectivement à la résolution des équations de l'hydrodynamique lagrangienne et à la résolution d'équations de diffusion anisotrope sur des maillages bi-dimensionnels non-structurés. Le premier schéma, dénommé EUCCLHYD (Explicit Unstructured Lagrangian HYDrodynamics), permet de résoudre les équations de la dynamique des gaz sur un maillage mobile qui se déplace à la vitesse du fluide. Il est obtenu à partir d'un formalisme général basé sur le concept de forces de sous-mailles. Dans ce cadre, les flux numériques sont exprimés en fonction des forces de sous-mailles et de la vitesse des noeuds. Leur détermination repose sur les trois principes fondamentaux suivants : compatibilité géométrique entre le mouvement des noeuds et la variation de volume des mailles (loi de conservation géométrique), compatibilité avec le second principe de la thermodynamique et conservation de l'énergie totale et de la quantité de mouvement. L'extension de ce schéma à l'ordre deux est mise en place à l'aide d'une méthode basée sur la résolution d'un problème de Riemann généralisé dans l'approximation acoustique. Le second schéma, appelé CCLAD (Cell-Centered LAgrangian Diffusion), concerne la résolution de l'équation de la chaleur anisotrope non-linéaire. La discrétisation correspondante s'appuye sur une formulation variationnelle locale au niveau des sous-mailles qui permet de construire une approximation multi-points du flux de chaleur. Cette discrétisation d'ordre élevé rend possible la résolution des équations de la diffusion anisotrope avec une précision satisfaisante sur des maillages lagrangiens fortement déformés. La précision et la robustesse de ces méthodes numériques sont démontrées sur des cas-tests représentatifs.

In this study was, also, tested a comprehensive model that hypothesized that cognitive fusion has an impact on loneliness and psychological health, through higher experiential avoidance and less committed actions.The sample comprised 765 participants (304 individuals diagnosed with chronic physical disease and 461 individuals without a diagnosis of chronic physical disease), who completed an online survey. Participants with chronic physical diseases reported higher levels of cognitive fusion, experiential avoidance and feelings of loneliness, as well as lower levels of psychological health, when compared to participants without chronic physical disease.Correlation results showed that, in both groups, cognitive fusion was positively linked with experiential avoidance and feelings of loneliness and negatively linked with committed action and psychological health. The path analysis results confirmed the adequacy of the proposed model, which explained 36% of loneliness and 57% of the psychological health’s variances. Cognitive fusion is associated to loneliness and decreased psychological health, through higher levels of experiential avoidance and lower levels of committed action, even when controlling for the effect of age. Findings offer important suggestions on how the ACT core processes underlie loneliness and psychological health and give support the development of interventions that target cognitive defusion, acceptance skills and committed actions to reduce feelings of loneliness and increase psychological health.<br>Este estudo pretende explorar as diferenças entre indivíduos com e sem doença física crónica em relação aos processos centrais da ACT (fusão cognitiva, evitamento experiencial e ação não comprometida), aos sentimentos de solidão e à saúde psicológica.

Full textAbstract:
PhD Thesis in Comparative and Molecular Genetics<br>In the last decades, several were the efforts made on the characterization of satellite DNA (satDNA) families in several species, collecting clues and evidences of the sequences’ evolutionary mechanisms and clarifying putative functions of these ubiquitous DNA sequences. The invariable presence of these sequences at the primary constriction of mammalian chromosomes was one of the first evidences for a crucial role in the genome. Numerous authors have suggested a range of biological processes where satellite sequences and their transcripts may intervene, specifically in centromeric function, heterochromatin formation and maintenance, chromosome pairing and segregation, chromosome rearrangements, cell cycle control or gene expression regulation. SatDNA sequences are known to present a rapid generation and even elimination in phylogenetically related species, however some of these sequences seem to have been almost completely preserved, at least in a few copies, over long evolutionary periods in some genomes. The cattle genome harbors several distinct centromeric satDNA families with interrelated evolutionary histories, being a good model for the study of satDNA evolution. The satDNA families in the cattle genome are highly complex in their structure and organization, variable in number of copies and chromosomal distribution. Until now, several satDNA families were isolated from Bos taurus (cattle, Bovini tribe, subfamily Bovinae) genome, and some of these sequences’ motifs have been interestingly found in other species from the Bovidae family. In the present work, the nucleotide sequence and chromosome location of five cattle satDNA families was analysed in Bos taurus and in seven species from the tribe Tragelaphini (Bovinae subfamily). The satDNAs sequence similarity among the analysed species reflected different stages of homogeneity/heterogeneity, revealing the evolutionary history of each satDNA family over the Bovidae genome evolution. One of the analysed satDNA families (SAT1.723) stood out due to its presence at the chromosomes’ centromeres of all Tragelaphini species, as well as in two less related Bovidae species, Ovis aries and Capra hircus (Caprinae subfamily). The interactomic and in situ analysis showed the association of SAT1.723 with centromeric proteins revealing that this satDNA family is clearly involved in the centromeric activity in all the species analysed and that it is preserved for at least 15-20 My. Besides its centromeric location, SAT1.723 was detected (in silico) dispersed in the genomes of Bos taurus, Ovis aries e Capra hircus. An inspection on the SAT1.723 monomer-flanking regions showed the presence of transposable elements (TEs), what may explain its intense shuffling through the activity of this satDNA/TEs between different genomic regions. Considering the richness of Bovinae genomes in different (peri)centromeric satDNAs, the organization of these sequences in each genomes’ chromosomes was analysed in order to develop a centromeric physical map as a tool to study chromosomal rearrangements involving the centromeric regions, namely Robertsonian Translocations (robs). The interest in the study of robs derives not only from their high frequency in mammalian karyotype evolution, but also from their influence on fertility and disease. The formation of a rob chromosome implies the occurrence of double strand breaks at the centromeres of two acrocentric chromosomes, being satDNA sequences the core hotspot for these breaks. In this work, using (peri)centromeric satDNA families, two Robertsonian translocations were analysed: the cattle rob(1;29) as a chromosomal abnormality and as an evolutionary fixed rearrangement in other species from the Bovinae subfamily and one of the most frequent human robs, rob(14;21). The main aim of our study was determining the molecular mechanism(s) underling these frequent translocations. Analysing how satDNAs reorganize in the centromere of the translocated chromosomes, we were able to show that the analysed robs are multistep complex events, involving a precise elimination and reorganization of specific peri(centromeric) satDNA sequences. Our data highlight the active role of satDNA sequences in the robs’ translocation mechanism and reinforces the functional meaning of these repetitive sequences in the chromosomes’ stability, further suggesting the existence of a common mechanism of Robertsonian translocations’ occurrence.<br>Nas últimas décadas, vários têm sido os esforços feitos para caracterizar as diferentes famílias de DNA satélite (satDNA) em várias espécies, tendo-se reunido evidências dos mecanismos de evolução destas sequências de DNA repetitivas e começado a desvendar algumas das suas funções. A presença ubíqua destas sequências nos cromossomas de mamíferos foi uma das primeiras sugestões de uma função crucial nestes genomas. Numerosos autores têm sugerido uma série de processos biológicos onde as sequências de satDNA e os seus transcritos podem intervir, nomeadamente na função centromérica, formação e manutenção da heterocromatina, emparelhamento e segregação cromossómica, rearranjos cromossómicos, controlo do ciclo celular ou regulação da expressão génica. As sequências de satDNA são conhecidas pela sua dinâmica evolutiva que conduz à sua rápida formação e até mesmo eliminação, mesmo em espécies filogeneticamente relacionadas. Contudo, algumas dessas sequências parecem ter sido preservadas de forma inalterada, pelo menos em algumas cópias, durante longos períodos evolutivos em alguns genomas. No genoma de Bos taurus (gado bovino doméstico, tribo Bovini, subfamília Bovinae) podem ser encontradas várias famílias de satDNA centroméricas e pericentroméricas com histórias evolutivas interrelacionadas, sendo um bom modelo para estudar a evolução deste tipo de sequências. As famílias de satDNA no genoma de Bos taurus são altamente complexas na sua estrutura e organização, variáveis em número de cópias e distribuição cromossómica. Até agora, várias famílias de satDNA inicialmente isoladas do genoma de Bos taurus, foram já detetadas noutras espécies da família Bovidae. No presente trabalho foi analisada a presença, a sequência e a localização cromossómica de cinco famílias de satDNA em Bos taurus e sete espécies da tribo Tragelaphini (também pertencente à subfamília Bovinae). A análise destas sequências isoladas a partir dos genomas das várias espécies refletiu diferentes níveis de homogeneidade/heterogeneidade, revelando a história evolutiva de cada família de satDNA ao longo da evolução do genoma Bovidae. Uma das famílias de satDNA analisadas (SAT1.723) destacou-se devido à sua presença não só nos centrómeros dos cromossomas das espécies Bovini e Tragelaphini, mas também de duas espécies da família Bovidae filogeneticamente menos relacionadas, Ovis aries e Capra hircus (Subfamília Caprinae), encontrando-se muito conservada em todos os genomas analisados. O estudo de interatómica e a análise in situ mostrou uma associação do SAT1.723 com proteínas centroméricas, revelando que esta família de satDNA está claramente envolvida na atividade centromérica em todas as espécies analisadas, e que está preservada há pelo menos 15-20 milhões de anos. Para além da localização centromérica, o SAT1.723 foi detetado (in silico) de forma dispersa nos genomas de Bos taurus, Ovis aries e Capra hircus. A análise das sequências flanqueadoras dos monómeros de SAT1.723 mostrou a presença de elementos transponíveis (TEs), o que pode explicar a sua dispersão pela atividade deste satDNA/TEs entre diferentes regiões genómicas. Considerando o enriquecimento dos genomas da família Bovinae em diferentes satDNAs (peri)centroméricos, foi determinada a organização destas sequências nos cromossomas dos vários genomas, de forma a desenvolver um mapa físico do centrómero como ferramenta para o estudo de rearranjos cromossómicos que envolvam as regiões centroméricas, nomeadamente translocações Robertsonianas (robs). O interesse no estudo das robs surge não só pela sua elevada incidência durante a evolução cariotípica dos mamíferos, como também pela influência destes rearranjos na fertilidade e na doença. A formação de um cromossoma rob implica a ocorrência de quebras de cadeia dupla ao nível dos centrómeros de dois cromossomas acrocêntricos, sendo as sequências de satDNA o principal “hotspot” dessas quebras. Neste trabalho, usando famílias de satDNA (peri)centroméricas foram analisadas duas translocações Robertsonianas: a rob(1;29), presente em Bos taurus como uma alteração cromossómica, e evolutivamente fixada no cariótipo de espécies da tribo Tragalaphini; e uma das robs mais frequente na população humano, a rob(14;21). O principal objetivo do nosso estudo foi determinar os mecanismos moleculares subjacentes a estas translocações. Analisando como as sequências de satDNA são reorganizadas no centrómero dos cromossomas translocados, foi possível demonstrar que as robs analisadas são rearranjos complexos que ocorrem em múltiplas etapas, envolvendo uma eliminação e reorganização precisa de sequências de satDNA específicas. Os nossos resultados evidenciam o papel ativo das sequências de satDNA no mecanismo de translocação das robs e reforça a função destas sequências repetitivas na estabilidade cromossómica, sugerindo ainda a existência de um mecanismo comum para a ocorrência das translocações Robertsonianas.

L'étude présente un compte rendu non exhaustif des recherches sur les facteurs critiques de succès. Elle décrit la réalité lors de fusion d'établissements de santé et de services sociaux. Ces organisations doivent maintenant planifier et rationaliser. En vertu du projet de loi 120, les fusions fournissent un moyen d'atteindre ces objectifs.
La recherche rejoint douze établissements "centres d'hébergement et de soins de longue durée" formant cinq regroupements. L'analyse de certains facteurs critiques de succès retient l'attention. Ces facteurs portent sur: le modèle de gestion, l'atteinte des objectifs du service à la clientèle, l'exercice du travail et la fusion proprement dite.
La méthode de régression simple ou multiple analyse la cueillette de données par l'intermédiaire d'un système informatique utilisant le programme "statview". Ces données représentent la vision du personnel travaillant principalement au niveau du service à la clientèle.
L'étude sur le terrain et l'analyse des résultats permettent de dire qu'au niveau de la pratique de collaboration seulement 12% des répondants observent une amélioration et 25% la situent au même niveau. La compétition entre les établissements fusionnés semble toujours exister.
Au niveau du service à la clientèle, 26% des répondants y voient une amélioration et 46% le croient inchangé. Le facteur critique "exercice du travail" demeure relativement stable malgré l'absence remarquée des cadres.
Généralement, le jugement des répondants sur la fusion s'avère positif à l'exception des pratiques de collaboration où près de 60% des répondants considèrent que ça ne s'applique pas. Les aspects négatifs se retrouvent dans les questions ouvertes où les commentaires sur: l'augmentation de la hiérarchie, les problèmes de communication, l'absence des dirigeants et la mobilisation des énergies retiennent 1'attention.
Des problèmes de communication et de bureaucratie semblent s'installer dans ces organisations. Les améliorations à apporter se situent principalement au niveau des communications et du rôle de chaque intervenant.

This study interviews nurses who have taken care of patients with drainage tube after having spinal fusion surgery. The purpose of the study is to find out whether different treatments after the drainage tube slippage will increase a load of care or not. Meanwhile, is there any connection between treatment and cost of medical care.
The results showed that on average for hospital discharge, the treatment of spondylolisthesis drain to remove is 1.5 days less than to reset. Nurses proposed that to care neurosurgical patients with post-operative drainage tube is not a burden to them for it is part of routine. After interviewing both specialist and non-specialist nurses on the topic of resetting drainage tube slippage, they proposed three thoughts as following, 1. concerns with infection; 2. causes additional harm to patient; 3. enters into a controversy of drainage function remain. In terms of enhancing the quality of care, from the nurses’ standpoint, the drainage tube should not reset after its slippage.

Full textAbstract:
En 1982, suite à d'un décret ministériel, le Centre Hospitalier de la Région de la Beauce était créé. La formation de cet ensemble de santé, fruit de la fusion des deux (2) hôpitaux de la Beauce, à savoir l'Hôtel-Dieu Notre-Dame de Beauce situé à Saint-Georges et l'Hôpital Saint-Joseph de Beauceville, était perçue comme nécessaire par la majorité des intervenants locaux et régionaux. Tous reconnaissaient que la mise en commun des ressources et l'élimination des duplications pouvaient permettre d'offrir dans la région des services de santé de façon efficace et efficiente.
Malgré l'atteinte des objectifs, à savoir la résorption des déficits budgétaires et le développement de nouveaux services, le Centre Hospitalier de la Région de la Beauce fut démantelé en 1988. Ce travail se propose de découvrir les raisons de cet échec de la fusion; car si cette structure organisationnelle permet d'actualiser les objectifs parfois contradictoires d'accessibilité et de rentabilité, la connaissance des embûches qui compromettent son utilisation devient primordiale à ceux qui comme gestionnaires voudront profiter des bienfaits de cet outil de rationalisation.
Le cadre conceptuel s'articule selon trois (3) axes d'investigation. En premier, la pertinence du choix de ce modèle pour créer des liens entre des organismes de santé sera évaluée. Puis, l'intégration des différents facteurs organisationnels sera questionnée, à savoir si des différenciations selon les facteurs spatial, géographique, économique, psycho-social, culturel, et politique se sont maintenues ou sont apparues. Enfin le processus décisionnel sera évalué à la lumière de ses conséquences.
Grâce aux données recueillies par la consultation des archives des centres hospitaliers et surtout par l'interview de trente-quatre (34) intervenants représentant tous les secteurs, les conclusions suivantes ont été tirées. Le modèle d'arrangement interétablissement était approprié. Des écarts dans l'intégration du facteur politique ont entraîné des différenciations dans les facteurs géographique, spatial et culturel. Cette confrontation entre administrateurs-médecins aux conséquences néfastes pour l'organisation a été engendrée par un processus décisionnel déficient en ce qui a trait au partage des services entre les deux pavillons.
S'inspirant de Mintzberg, la conclusion suivante pourrait être tirée : une méritocratie professionnelle est devenue une arène politique parce qu'aucune planification stratégique n'est venue appuyer un partage de services entre les deux composantes du Centre Hospitalier de la Région de la Beauce.

碩士<br>中臺科技大學<br>醫療暨健康產業管理系碩士班<br>102<br>National Health Insurance(NHI) payment is the main financial source of hospitals. Therefore, the reform of NHI payment system has a huge impact on the operation and management of hospitals. This research is aiming at analyzing the balance of Tw-DRGs disbursement and medical expenditure after implementing the 2nd phase Tw-DRGs, exploring the impact on subject hospital and the cause of the balance difference. This research can be used as a reference for hospitals in management and cost monitoring to adapt to the reform of NHI payment policies. In hopes of becoming a reference factor for BNHI when drafting Tw-DRGs disbursement, and to plan a more reasonable and fair DRG payment system.
This research used retrospective data analysis to study 23,956 hospital inpatient claims from 2011 to 2012, to examine the balance of medical expenditure and the Tw-DRGs disbursement for “combined anterior and posterior spinal fusion (DRG496)”. This study helps to explore the medical expense disbursement structure and the factor that influenced the balance differences. We conducted several data analysis using SPSS 17.0 software, including descriptive statistics, independent-sample t-test, one way ANOVA, and chi-square test.
Results are as following: 1. DRG496 medical expenditure has significant difference between patient’s gender, age, doctor’s seniority, divisions, and whether there is post-operative infection. ; 2. Doctor’s seniority and division both has significant influence on post-operative infection and inpatient days; 3. Among the expense of DRG496, bone material account for 56.11% of the total medical expenditure (short segment spinal fusion). Long segment spinal fusion account for 102% of the medical expenditure. The types of operation has significant difference on the blance differences.; 4. With the increase of age and complications, inpatient days and medical expense also increase.
Conclusion: bone material accounts for 56.11% of the DRG496 NHI disbursement, however, the bone material fee in spine surgery is subsidized only after the application approval by BNHI. If it is not approved, patients will have to pay on their own. Thus, the current expense estimation for DRG496 disbursement is in fact a bit low. It is more reasonable to include those self-paid bone material fees into estimation, or to exclude all disbursement of bone materials and calculate the relative weight first then adding bone material fees into DRGs fixed disbursement. And it should be categorized using different types of operation. Medical expense is also significant related to age, complications, and types of fixation, and should all be listed as the factors for payment planning.

碩士<br>中臺科技大學<br>醫療暨健康產業管理系碩士班<br>107<br>Objective: This study aims to explore expenses of medical resource utilization and differences of reimbursement of National Health Insurance (NHI) to spinal fusion surgeries (DRG coding 496, 497, and 498 respectively) after the second phase of DRG version 3.4 was implemented in a regional teaching hospital from central Taiwan.
The analyzed factors included: 1) patient characteristics (gender, age, BMI, comorbidities or complications), 2) physician characteristics (department, years of experience, surgery cases), 3) disease characteristics (admission information, number of diagnoses, number of treatments), and 4) healthcare quality (post-operative infection, lengths of inpatient hospitalization, returning back to hospital within 14 days after being discharged). After resulting, we attempts to propose better strategies and improvement solutions in response to this newer version of TW-DRGs payment system for target hospital in this case study.
Methods: This research employed a retrospective method by secondary data. After eliminating some inadequate or unsuitable cases, there were 954 patients were selected for analysis by payments of DRG496, DRG497 and DRG498 during 2016 to 2018 from "Inpatient Medical Expenses List Details and Reporting Fee" in this study. Besides, a total of 15 physicians were selected to discuss from human resource management data bank according to the target hospital. The analysis themes were then compared the selected data for medical resources consumption, healthcare quality, and healthcare expenses. Research data were first collected and analyzed by using Microsoft EXCEL. Then SPSS 22.0 was in turn employed to analyze descriptive statistics and inferential statistics, including chi-square test, t-test, ANOVA and logistic regression to compare differences and relevance among respective variables.
Results: The results showed that there were: 1)significant correlations among postoperative infections and variables of patients gender (p＜0.05), comorbidities or complications (p＜0.01), and treatment numbers of disease (p＜0.01); 2) significant correlation among lengths of inpatient hospitalization and variables of patients gender (p＜0.01), age (p＜0.05), comorbidities or complications (p＜0.001), departments of physician (p＜0.001), experience years of physician (p＜0.001), surgical operation loading (p＜0.001), numbers of disease diagnoses (p＜0.01), and treatment numbers of disease (p＜0.01); 3) significant correlation between returning back to hospital within 14 days after being discharged and surgical operation loading (p＜0.05). 4) The older patients, higher BMI numbers, with comorbidities or complications, more diagnoses and treatment, longer lengths of inpatient hospitalization tend to cause higher average healthcare expenses. 5) By logistic regression analysis, there were significant correlation among postoperative infections, medication fee (p＜0.05), and injection technical fee (p＜0.05). Besides, there were significant correlation among lengths of inpatient hospitalization, diagnoses fee (p＜0.001), ward fee (p＜0.001), disease treatment fee (p＜0.01), surgery fee (p＜0.01), and blood plasma fee (p＜0.05). In addition, there were significant correlation among returning back to hospital within 14 days after being discharged, ward fee (p＜0.05), and inspection fee (p＜0.05).
Conclusions: The implementation of newer version of TW-DRGs payment system had substantially impacted financial and operational strategies of hospitals. The study results disclosed many potential factors of impacting the financial issues in the target hospital. In order to maintain or even better to improve operational performance of the hospital, we proposed following suggestions which including clinical paths need to be revised immediately, a proportional physician fee (PPF) be established, and a connected function for paying the difference of TW-DRGs payment system be implemented, cost control and target operational management be implemented and etc.

Full textAbstract:
Service brand has become a key factor for Chinese home furnishing malls to enhance
competitiveness under the commercial tenant system. However how to build a service brand
is still a much discussed question and the literature is scant on research specifically addressing
the brand building process in the particular case of home furnishing malls. Taking the case of
Fusen Noble House in Chengdu, China as a case study, the aim of this research is to explore
empirically the building process of a service brand in a special case of a Chinese home
furnishing mall. Based on the literature review, the research starts by designing a theoretical
framework of service brand building and then uses personal interviews and questionnaires for
data collection. Data is coded and analysed and a new model redesigned. Findings show that
the most important driving forces in the brand building process of the company studied are
senior managers, customer information and competitors, with senior managers being the most
important. In what concerns the guarantee or support mechanisms of service brand building,
results also show that they mainly include corporate strategy and organizational culture. The
key is for corporate strategy and organizational culture to match the service brand, while the
role of incentive mechanisms is less significant. The case also revealed the existence of a
clear process of service brand building following certain developmental steps. Although the
process tends to be highly informal, it still followed the basic order of service brand auditing,
service brand identification, service brand positioning and service brand implementation, with
an emphasis on external marketing. The thesis concludes with a discussion on the managerial
and research implications.<br>O conceito de marca aplicado à indústria de serviços é um fator chave na
competitividade e diferenciação dos centros comerciais especializados no setor da construção
e decoração de interiores na China. Qual a melhor forma de construir uma marca no caso da
indústria de serviços continua a ser uma questão muito debatida e a literatura existente é ainda
escassa sobre este assunto, em especial no caso específico deste tipo de centros comerciais em
larga escala. Utilizando o método do estudo de caso, esta tese selecionou a empresa Fusen
Noble House em Chengdu, China, com o objetivo de entender, de uma forma empírica, qual o
processo de construção da marca neste caso específico e quais as forças motoras dessa
construção. Com base na revisão da lieratura, a investigação começou por conceber um
modelo teórico de desenvolvimento de marca procurando em seguida recolher dados que
permitissem validar esse modelo. Os dados foram recolhidos através de entrevistas pessoais e
de questionários tendo-se chegado a um novo modelo concetual que reflete a situação da
empesa estudada. Em resumo, os principais resultados revelam que os gestores de topo, a
informação dos clientes e dos concorrentes constituem as principais forças motoras do
processo de construção da marca na empresa estudada sendo a gestão de topo o fator mais
importante. No que respeita aos mecanismos de apoio e garantia, os principais elementos, de
acordo com os resultados, são a estratégia e a cultura da organização. O essencial é que a
marca corresponda à cultura e à estratégia da organização tendo-se concluído que mecanismos
de incentivos assumem um papel menos importante. Este estudo de caso revelou também a
existência clara na empresa de um processo na construção da marca obedecendo a
determinadas etapas de desenvolvimento. Embora o processo tenda a ser bastante informal
verificou-se que ele seguiu a ordem geralmente atribuída à construção de uma marca de
serviços, nomeadamente, auditoria, identificação, posicionamento e implementação da marca,
com enfâse especial no marketing externo. A tese conclui com uma discussão sobre as
implicações dos resultados para a gestão e para a investigação.

Uma divisão celular bem sucedida depende de uma coordenação precisa da mitose. Sabe-se
que a levedura S. cerevisiae tem um gene – Mob1 – que codifica para uma proteína
reguladora, essencial para a saída da mitose.
Em humanos existem 7 genes do tipo Mob1, sobre os quais ainda há pouca informação.
Estudos preliminares realizados em células humanas indicaram que o gene humano Mob2 é
essencial para a realização da mitose, mais concretamente para a correcta formação do fuso
mitótico, afectando posteriormente o alinhamento e a segregação dos cromossomas. A função
do gene hsMob2 parece ser essencial para a organização dos centrossomas. Isto sugere que o
gene hsMob2 possa ser um dos causadores da instabilidade genómica observada, por
exemplo, em células cancerosas.
Neste projecto pretendeu-se compreender qual é a função do gene hsMob2. Para isso, optouse
por determinar a localização intracelular da proteina codificada pelo gene hsMob2,
recorrendo a técnicas de imunofluorescencia e imunolocalização.
Concluiu-se que a proteina hsMob2 tem uma localização intracelular dinâmica, localizando
no corpo central e nos centrossomas. Para além disto a proteína hsMob2 parece também estar
presente no fuso mitótico (em metafase) e na zona central do fuso (em anafase).
