description: Le modele d'adoption base sur les preoccupations suscitees par l'innovation (Concerns-Based Adoption Model--CBAM) est une approche operationnelle qui s'appuie sur certains postulats relies a la personne et a son developpement. La premiere question de recherche s'interesse aux changements dans les preoccupations des enseignantes et des enseignants. Il y a eu peu de changement dans les preoccupations. A la deuxieme question, les resultats demontrent que tres peu d'enseignantes et d'enseignants utilisent la telematique en salle de classe. La troisieme question de recherche se rapporte aux opinions des enseignantes et des enseignants face a la telematique. La personnel enseignant croit que la telematique a un role a jouer dans leur enseignement et aussi dans l'apprentissage des eleves. La quatrieme question suggere l'existence de relations entre les preoccupations, les comportements et les opinions due personnel enseignant. L'experience n'a pas demontre de facon precise la relation entre les genres de preoccupations et les niveaux d'utilisation telle que le preconise CBAM. En conclusion, cette experience d'exploitation de la telematique n'a pas obtenu les resultats esperes. Malgre les ressources materielles, financieres et humaines disponibles, la plupart des enseignantes et les enseignants n'ont pas adopte l'innovation dans leurs pratiques pedagogiques.

description: An ethnographic work about Japanese women who wear Lolita fashion, based primarily upon anthropological field research that was conducted in Tokyo between May and August 2014. The main purpose of this study is to investigate how and why women wear Lolita fashion despite the contradictions surrounding it. An additional purpose is to provide a new perspective about Lolita fashion through using interview data. Fieldwork was conducted through participant observation, surveying, and multiple semi-structured interviews with eleven women over a three-month period. It was concluded that women wear Lolita fashion for a sense of freedom from the constraints that they encounter, such as expectations placed upon them as housewives, students or mothers. The thesis provides a historical chapter, a chapter about fantasy with ethnographic data, and a chapter about how women who wear Lolita fashion are related to other fashions as well as the Cool Japan campaign.

description: Les représentations médiatiques ne sont pas neutres : elles occupent le lieu de l’imaginaire collectif et conditionnent l’action sociale. Cette thèse s’intéresse particulièrement à la performativité du langage dans la presse sportive comme forme de représentation sociale. Les réflexions théoriques qui la portent sont héritées principalement de John L. Austin et de Judith Butler. La démarche privilégie le concept de performativité pour décrire et évaluer les représentations des femmes athlètes dans la presse sportive canadienne. Ce concept de performativité correspond à la capacité du langage à agir sur le monde, à mobiliser vers l’action voire à transformer les perceptions et les interprétations établies. Les énoncés performatifs accomplissent l’acte qu’ils énoncent par le fait même qu’il l’énonce et opèrent par la redondance, c’est-à-dire par un effet répétitif qui consolide les représentations proposées, les stéréotypes dominants. En contre-partie à cet effet de consolidation, la performativité subversive se présente comme moyen d’intervention pour déstabiliser les assignations normatives et laisser place à de nouveaux schèmes. Puisque la thèse se concentre sur les représentations véhiculées dans la presse sportive, la recherche s’articule autour des questions suivantes : le vocabulaire dans la couverture sportive renforce-t-il les représentations traditionnelles du genre en sport, ou dégage-t-il des pratiques journalistiques de performativité subversive? Les représentations médiatiques des athlètes sont-elles similaires en anglais et en français? Une analyse de contenu quantitative et qualitative des Jeux olympiques de 2010 dans La Presse et le Globe and Mail suggère que les journalistes ont principalement recours à des pratiques de performativité subversive, car les hommes et les femmes athlètes sont généralement présentés de façon similaire. Des variables étudiées, deux (16,7%) s’inscrivent dans une performativité traditionnelle, quatre (33,3%) sont un lieu d’entre-deux et six (50%) reflètent des pratiques de performativité subversive. Le concept de performativité met en lumière l’existence d’une phase de transition dans le journalisme sportif alors que les stéréotypes traditionnels y sont moins présents. Une distinction s’observe toutefois entre les représentations anglophones et francophones. Les journalistes de La Presse ont davantage recours à des pratiques de performativité qui reprennent du traditionalisme. Cette observation repose sur une stratégie culturelle de la part des média québécois qui s’approprient la vie tant professionnelle que privée des athlètes pour les rapprocher des lecteurs.

description: With the rapid advancements of the internet of things, systems including sensing, communication, and computation become ubiquitous. The systems that are built with these technologies are increasingly complex and therefore require more automation and intelligent decision-making, while often including contact with humans. It is thus critical that such interactions run smoothly in real time, and that the automation strategies do not introduce important delays, usually not larger than 100 milliseconds, as the blink of a human eye. Pushing the deployment of the algorithms on embedded devices closer to where data is collected to avoid delays is one of the main motivations of edge computing. Further advantages of edge computing include improved reliability and data privacy management. This work showcases the possibilities of different embedded platforms that are often used as edge computing nodes: embedded microcontrollers, embedded microprocessors, FPGAs and embedded GPUs. The embedded solutions are compared with respect to their cost, complexity, energy consumption and computing speed establishing valuable guidelines for designers of complex systems that need to make use of edge computing. Furthermore, this paper shows the possibilities of hardware-agnostic programming using OpenCL, illustrating the price to pay in efficiency when software can be easily deployed on different hardware platforms.

description: Over the past two decades, our concept about the distribution of life on Earth has fundamentally changed. Microorganisms (bacteria and archaea) colonize not only the upper soil layers, but the underlying sediments and rocks as well. Previous estimates assumed that up to 94 % of all microorganisms live in deep subsurface sediments, but recent findings show that microbial abundance in the marine subsurface is much lower than previously estimated. However, these deeply buried communities are as important as the surface biosphere for driving carbon and nutrient cycling and catalyzing a multitude of reactions between rocks, sediments, and fluids. Due to their low abundance and low metabolic rates, studies of deep biosphere microorganisms require special analytical procedures. Therefore we developed an integrated research strategy, which connects geochemical measurements of sediment properties with  microbiological/molecular biological analyses of microbial communities and modeling of microbial pathways/ networks. Our ongoing studies in sediments of the El’gygytgyn Crater Lake and of the South Pacific Gyre show the importance of microorganisms for the element cycles in these extreme environments. The composition of microbial communities, their role in major biogeochemical cycles and their response to changing environmental conditions, however, are still largely unknown. The future research of the German Centre for Geosciences GFZ will extend our knowledge on the role of microorganisms mainly in continental deposits, especially their impact on biogeochemical cycles, mineral weathering as well as on the quality and stability of reservoirs in the broadest sense.
How the tobacco industry is gaming Australian health regulations

description: Australia's tough tobacco regulations are acting as a catalyst for the industry to develop sophisticated marketing practices. These companies are gaming the system by anticipating regulatory impact and then using unregulated marketing elements to overcome it. Australia has been a guiding light for countries looking to improve public health through the effective regulation of tobacco, which remains the world's biggest cause of preventable illness and death, and still kills around 15,000 Australians annually. December 2012 saw the implementation of Australia's innovative plain packaging legislation, this was followed by four 12.5% annual tobacco tax excise increases. As a result the number of Australian smokers has fallen to a record low. However the tobacco industry has used several strategies, including price reduction, brand differentiation and promoting the idea of healthier cigarettes, to undermine Australia's new regulatory environment.

description: Geodynamic processes inside planet earth drive crustal scale tectonics and surface processes some of which are associated with geohazards. Because the driver is slow, hazardous events occur infrequent enough to escape society’s generally short-term awareness. However, its ultimate impact on society can be significant as evidenced by recent geo-catastrophes like the Sumatra and Japan subduction earthquakes and tsunami. Physical modelling of geohazards therefore becomes an increasingly important tool to understand our longterm exposure. At GFZ we combine analogue and numerical models in order to better understand the interplay between geodynamic processes at depth and geohazards like earthquakes, landslides and tsunamis. By simulating long time series of continuous and episodic processes, we provide archives of potentially hazardous events that allow statistical analysis beyond the instrumental record and, together with physics-based modeling a deeper knowledge of the underlying processes with the aim to provide probabilistic and, where reasonable, deterministic predictions of spatio-temporal pattern of tectonic hazards.

description: Least squares is used to fit a model to the individual match results in English football and produce a Home Ground Advantage (HA) effect for each team in addition to a team rating. We show for a balanced competition this is equivalent to a simple calculator method using only data from the final ladder. The existence of a spurious HA is discussed. HA's for all teams in the English Football league from 1981-82 to 1990-91 are calculated, and some reasons for their differences investigated. A paired HA is defined and shown to be linearly related to the distance between club grounds.

description: As Alfred Wegener already recognized 100 years ago, the giant southern continent, Gondwanaland, broke about 200 million years ago into several pieces which drifted apart. One part, India, drifted northward until it collided 50 million years ago with Eurasia.
This collision created the Himalayan mountain chain and the Tibetan plateau, which are not only very significant geological structures, but are also important parts of the Earth System. The influence of Tibet on the atmospheric circulation and world climate and the ongoing threat of giant collisional earthquakes to the megacities in the Ganges plain must be emphasized. In international cooperation, the GFZ conducted a number of seismic experiments in Tibet, known as INDEPTH experiments, to study details of the deformation of the tectonic plates as a consequence of the collision. As a result the presence of the Indian lithosphere was for the first time seismologically demonstrated to exist several hundred kilometers northwards below Tibet. During the collision the Indian crust was peeled off and contributes to the thickening of the Tibetan crust. The latest phase of the INDEPTH experiments was focused on the northern margin. Using active and passive seismic techniques (wide-angle profiling, receiver functions, surface wave tomography), we have imaged the deep structure below Tibet, showing the configuration of the Tibetan lithosphere between the Indian and Eurasian plates. We also found evidence for unusual properties of the lower crust, which are likely to be responsible for the prevalence of crustal flow in northern Tibet.

description: La thèse est une étude de cas concernant la version française des textes que comportent deux pages Web de l’Agence de la santé publique du Canada. Ces pages ciblent les parents, leur offrant de l’information sur les maladies évitables par la vaccination et sur les vaccins. Or, la fonction informative y est secondaire et tributaire de la fonction persuasive, car l’Agence souhaite persuader les parents de faire vacciner leur enfant. La composition des textes a exigé deux processus de traduction : un processus intralinguistique à partir de textes comprenant de l’information sur les maladies et les vaccins et un processus interlinguistique de l’anglais vers le français. L’étude consiste à démontrer que puisque la fonction informative des communications visant à influencer les comportements en matière de santé est subordonnée à leur fonction persuasive, les choix de traduction doivent favoriser la fonction persuasive. L’objectif est de montrer au moyen de trois analyses que certains choix effectués en créant la version française des textes atténuent la fonction persuasive. La première analyse concerne le contexte et la finalité des textes et vise à déterminer pourquoi la fonction principale est persuasive plutôt qu’informative; la deuxième analyse se rapporte à la version anglaise et vise à déterminer de quelle manière les choix effectués dans le cadre du processus de traduction intralinguistique favorisent la fonction persuasive; la troisième analyse porte sur la version française et vise à mettre en évidence les choix de traduction interlinguistique qui atténuent la fonction persuasive. En conclusion, l’étude montre que certains choix de traduction interlinguistique atténuent la fonction persuasive de la version française parce qu’ils ne reflètent pas de façon cohérente les choix de traduction stratégiques effectués dans le cadre du processus de traduction intralinguistique.

description: Most of our knowledge of the Earth’s interior results from seismological observations. The measurements are based on the fact that different rock types show different physical properties, and that seismic waves (e.g., from earthquakes or explosions) travelling
through the Earth can be observed at the surface and be used to infer the internal architecture. Early seismological observations revealed the layered structure of the Earth, and today scientists are working on imaging the regional and local structural variations
to better understand the geological processes and dynamics forming the Earth. However, seismic methods are also utilized to reveal the shallow parts bearing important resources such as hydrocarbons, water, or mineral deposits. In every case, the challenge for these seismic methods is to provide ever detailed images of the subsurface. One important step
toward this aim is to increase the number of observations which can often be achieved by increasing the number of recording instruments. Recent technological advances in the field of A/D-converters, GPS receivers, and data storage led to the development of very compact autonomous recorders with a significantly reduced power consumption. Now, more instruments can be transported and installed with less personnel and costs, which results in significantly denser spatial sampling of the seismic wave field, thus eventually yielding better resolved subsurface images.
Essays on the Causal Relationship Between Short-Term and Long-Term Interest Rates

description: This thesis is about the causal relationship between interest rates. In chapter 1, with the help of time-series econometrics and by applying linear Granger causality tests based on the Toda-Yamamoto approach, the linear causality directions between the federal funds rate and five different interest rates during the last seven business cycles in the U.S. are investigated. We also examine the linear Granger causality directions between the overnight rate and five other interest rates during the last three business cycles in Canada. In chapter 2, the Diks and Panchenko Granger causality test is applied to explore the nonlinear causality effects between the short-term and long-term interest rates. By combining nonlinear causality effects with the linear ones which are found in the first chapter, it is seen that during the related periods in the U.S. and Canada, the most common Granger causality direction between short-term and long-term interest rates is a bidirectional one. Moreover, our findings show that during recent periods, the federal funds rate and overnight rate Granger cause other interest rates significantly. In chapter 3, the rolling window strategy is employed to detect the linear and nonlinear Granger causality relationship between the federal funds rate and the 10-year government bond rate, during different time horizons, investigating whether these causalities change with the passing of time. Our findings show that during different time horizons, there is a significant two-way Granger causality relationship between these interest rates. Although we have a different interpretation of the existence of bidirectional causation between short-term and long-term interest rates, this conclusion provides some support to some post-Keynesian structuralists viewpoints like Pollin (2008). However, Pollin's claim indicating that with the passing of time the significant causality effects of the federal funds rate to the market rates becomes insignificant is not supported by the current thesis findings because our results demonstrate that these causality effects have not been diminishing over the most recent business cycles.

description: L’écosystème médiatique canadien est en pleine ébullition. La fragmentation des marchés rend graduellement obsolète le concept de télévision généraliste. Le numérique amène une netamorphose de la consommation et de l’usage que nous faisons des plateformes traditionnelles. S’ajoute un effritement des revenus publicitaires et des parts de marchés. Comme ses compétiteurs, la Société Radio-Canada (SRC) doit se réinventer. Un défi de taille s’ajoute à son fardeau : son budget se voit considérablement diminué depuis les cinq dernières années. Alors que les attentes envers la SRC sont hautes à cause de son mandat défini par la Loi sur la radiodiffusion, mais aussi par les exigences du CRTC, certains observateurs commencent à craindre que la société de la Couronne n’arrive plus à réaliser son mandat. Dès lors, une bataille de l’opinion publique s’est mise en branle. Nous avons identifié quatre acteurs qui sont appelés à réagir à cette situation. À l’aide de l’analyse de discours, nous nous sommes intéressés à la composition des différents discours, des trames narratives de chacun et de leur place dans la sphère publique. Nous cherchons à déterminer les liens et les dichotomies entre les différents discours afin de mieux comprendre comment et pourquoi les acteurs ont su transmettre les informations nécessaires à leur position dans l’enjeu.

description: The relationship between social class and electoral behaviour in Australia is changing. In the 1960s the majority of working-class voters supported the Labor Party; in 1996 more working-class voters (manual workers and people in routine clerical jobs) voted for the Coalition than for Labor. A perception among some members of this group that Labor no longer reflects either their cultural values or their economic interests may help explain this shift.

description: The Earth’s magnetic field has undergone temporal and spatial variations including polarity reversals. Paleomagnetic and historical magnetic field measurements suggest persistent distinct patterns of variation of the geomagnetic field taking place in different regions of the Earth. At least on the millennia time scale these patterns may be explained by the thermal influence of Earth’s mantle on the geodynamo. Whether this influence can already be discerned on the century time scale is still debated. Although, the Earth’s interior is inaccessible for direct observations, the effects of such processes at the top of the core and below are well observed at the Earth’s surface. Several observables of these processes are used to infer the dynamical regime of Earth’s outer core and its interaction with its vicinity.
Structural Insights from the NMR Spectroscopy of Quadrupolar Nuclei: Exploiting Electric Field Gradient and Spin-Spin Coupling Tensors

description: NMR spectroscopy has evolved into one of the most important characterization techniques in chemistry with which it is possible to obtain valuable structural, dynamical, and mechanistic information. Most applications of NMR have however been limited to the use of nuclei having spin quantum numbers of 1/2. This thesis discusses the developments that have been advanced in order to extract quantitative structural information from the NMR spectroscopy of quadrupolar nuclei (spin, I>1/2) which account for the vast majority of the NMR-active nuclei. In a first part of the thesis, a NMR crystallographic method is developed which uses the electric field gradient tensor measured at the nuclear sites as an experimental constraint in DFT-based crystal structure refinements. This inclusion of experimental data into crystal structure refinements enables the determination of higher quality, and experimentally-relevant, structures. We apply this new methodology in order to determine higher quality crystal structures for the non-linear optical material Na2B2Al2O7, sodium pyrophosphates, and the near-zero thermal expansion material ZrMgMo3O12. In a second part of this thesis, experimental techniques are developed for the measurement of spin-spin coupling between pairs of quadrupolar nuclei; the measurement of spin-spin coupling carries with it extremely valuable distance and connectivity information. Using DOR NMR, heteronuclear residual dipolar coupling as well as homonuclear J coupling multiplets can be observed. Notably, the J coupling between quadrupolar nuclei can still be measured in A2 spin systems, unlike in the case of pairs of spin-1/2 nuclei. The theory that was developed for the characterization of these multiplets was extended for the general simulation of exact NMR spectra of quadrupolar. This program, known as QUEST, is now free to use by anyone in the scientific community. Pulsed J-resolved NMR experiments are then described which enable the facile measurement of J and dipolar coupling in homonuclear pairs of quadrupolar nuclei. Notably, the J splitting is greatly amplified in A2 spin systems which provides strong structural information and enables the precise detection of smaller J coupling constants. These techniques are applied towards directly studying gallium metal-metal bonding interactions as well as boron-boron bonds in diboron compounds of importance in β-boration chemistry.

description: The popularity of the Internet and cellular networks in recent years has led to widespread use of these networks for data dissemination. Advancements in wireless communications networks like Long Term Evolution (LTE) and 5G networks indicate a trend towards higher speed mobile networks accessed by users with increasingly sophisticated mobile devices. These advancements do not include the means for users to leverage increased wireless network transmission rates by disseminating heterogeneous data. The ability to share heterogeneous data entirely through mobile networks illustrates a communications methodology where end users determine what data will be shared with no limitations based on content. Advances in this domain have introduced many aspects of this methodology on a global scale but have not addressed how heterogeneous data can be defined and distributed by end users. This thesis proposes a communications architecture for the dissemination of heterogeneous data in real-time. The implementation of this communications architecture is based on the IP Multimedia Subsystem (IMS) and proposes modifications to the Session Initiation Protocol (SIP) to permit the distribution of heterogeneous data through synchronous and asynchronous data transmission. A communications protocol is introduced defining a broker, data consumers, data producers and a message format. Algorithms for session management and packet processing are provided in an embedded system called the Reconfigurable Multimedia Collaborative System (RMCS). Results for the communications architecture demonstrate the successful generation and transmission of heterogeneous data in real-time using the proposed modifications to SIP. The successful operation of packet generation algorithms and related functions in hardware is also provided to demonstrate the means through which this architecture could be provided through hardware for optimal performance and to facilitate its implementation into mobile devices.

description: Seismological and other geophysical observations from the surface show that the internal structure of our planet consists of concentric layers: the crust (on which we live), the mantle and a metallic core. However, even the deepest drill holes can access less than 1 percent of the Earth depth for chemical/physical measurements or sampling. A multidisciplinary approach combining geophysics,
geochemistry, petrology and geodynamic modeling is required in order learn more about the deep Earth.
Mineral physics provides data at high pressure measured in the laboratory. High pressure measurements performed at the GFZ in the framework of an international cooperation showed that the spin transition of divalent iron in ferropericlase (Mg,Fe)O has a major effect on the elastic properties at conditions existing in the lower mantle. This spin transition of (Mg,Fe)O is caused by a pressure induced spin pairing of the 3d electrons between 40 and 60 GPa. The measurements showed that the bulk modulus and the density of ferropericlase increase by several percent at this pressure regime. Moreover, the shear wave velocity anisotropy increases by about 60 % in the same pressure range. These results suggest that the anisotropy in lowermost mantle is caused by the texture of the ferropericlase rather than by perovskite that is about four times more abundant.
Additional new experiments performed on a synthetic mantle rock at the synchrotron light source PETRA III (DESY, Hamburg) have the potential to reveal the development of texture in rocks subject to the extreme pressures and temperatures conditions present in the very deep mantle of the Earth.

description: Processes near the Earth’s surface are linked to the deep mantle and core. From plate reconstructions, we can infer where slabs have been subducted through geologic time and the distribution of slabs throughout the mantle, which can be compared with seismic tomographic images. When slabs approach the core-mantle boundary (CMB), they push the thermal boundary layer ahead, leading to large lateral variations in heat flux from the core to the mantle: Beneath regions of subduction, we compute heat flux of several hundred mW/m2, whereas in areas where hot material has resided for long times, it is < 10 mW/m2. CMB heat flux likely influences the geodynamo, yet we are only beginning to understand such core-mantle processes. Seismology indicates there are large domes of geochemically distinct materials in the lowermost mantle which possibly represent old oceanic crust that was subducted during the billions of years of plate tectonics. Hot mantle plumes are mainly generated from the margins of lower mantle heterogenieties, where hot material pushed ahead of slabs is forced to rise. The largest and hottest plumes entrain a large amount (up to 20 %) of the former oceanic crust and carry it to the base of the lithosphere. This material has lower melting temperature than “normal” peridotitic mantle and contains huge amounts of CO2, HCl and other components that are toxic for the environment. Mantle plumes rich in such material produce exceptional volume of melts and cause extreme pollution of the atmosphere and hydrosphere. This happened 252 Mln years ago, when millions of cubic km of lava were erupted in Siberia in the time of a few hundred thousand years or less. That led to the Permo-Triassic mass extinction, the largest environmental catastrophe in Earth history when more than 90 % of all species on land and in the ocean became extinct.
The Subparsec-Scale Structure and Evolution of Centaurus A. II. Continued Very Long Baseline Array Monitoring

description: We present the results of continued 8.4 GHz Very Long Baseline Array monitoring of the subparsec- scale structure and evolution of Centaurus A, following on from the initial results presented in 1998 by Tingay et al. We include, for the first time, multiepoch VLBI images at 22.2 GHz that show that the jet is linear and well collimated on scales as small as 0.02 pc (∼1000rs). Two components in the subparsec- scale jet continue to evolve slowly with a speed of 0.12c. We confirm that an additional component, close to the core, has no significant motion. Some evidence is seen for rapid variations within individual components, as noted dramatically in 1991-1992 by Tingay et al., albeit at a lower level of activity. Both the stationary behavior of the component close to the core and the internal variability of components in the subparsec-scale jet of Centaurus A may be explained as being due to the existence of shocks created in the wake of major component ejections from the nucleus, as simulated by Agudo et al. (published in 2001). Tentative evidence is found to suggest that two subparsec-scale counterjet components are in motion away from the nucleus. The estimated apparent speeds of the jet and counterjet components are consistent with the previously suggested likely jet viewing angle range, 50°-80°. We also compare our Centaurus A images with high-resolution VLBI images of M87 to show that the region of the Centaurus A jet in which collimation likely first occurs lies a factor of 10 below our current resolution limit. Future space VLBI missions at high frequency will be required to resolve this region.

description: Power demands will increase day-by-day because of widely adopting of Plug-in Electric Vehicles (PEVs) in the world and growing population. Finding and managing additional power resources for upcoming demands is a challenge. Renewable power is one of the alternatives. However, to manage and control renewable resources, we need suitable Energy Storage System (ESS). PEVs have a large battery pack that is used mainly to supply electric motor. Moreover, PEV battery could be used as an ESS to store power at a certain time and use it at another time. Nevertheless, it can play the same role with electric power grids, so it can store power at a time and return it at another time. This role might help the grid to meet the growing demands. In this thesis, we propose a charging and discharging coordination algorithm that effectively addresses the problem of power demand on peak time using the PEV’s batteries as a backup power storage, namely, Flexible Charging and Discharging (FCD) algorithm. The FCD algorithm aims to manage high power demands at peak times using Vehicle to Home (V2H) technologies in Smart Grid and PEV’s batteries. Intensive computer simulation is used to test FCD algorithm. The FCD algorithm shows a significant reduction in power demands and total cost, in proportion to two other algorithms, without affecting the performance of the PEV or the flexibility of PEV owner’s trip schedule.

description: Gain-of-function mutations in human androgen receptor (AR) are among the major causes of drug resistance in prostate cancer (PCa). Identifying mutations that cause resistant phenotype is of critical importance for guiding treatment protocols, as well as for designing drugs that do not elicit adverse responses. However, experimental characterization of these mutations is time consuming and costly; thus, predictive models are needed to anticipate resistant mutations and to guide the drug discovery process. In this work, we leverage experimental data collected on 68 AR mutants, either observed in the clinic or described in the literature, to train a deep neural network (DNN) that predicts the response of these mutants to currently used and experimental anti-androgens and testosterone. We demonstrate that the use of this DNN, with general 2D descriptors, provides a more accurate prediction of the biological outcome (inhibition, activation, no-response, mixed-response) in AR mutant-drug pairs compared to other machine learning approaches. Finally, the developed approach was used to make predictions of AR mutant response to the latest AR inhibitor darolutamide, which were then validated by in-vitro experiments.

description: The theory of electromagnetic characteristic modes was published roughly forty years ago, for both conducting and penetrable objects. However, while the characteristic mode analysis of conducting objects has found renewed interest as a tool for antenna designers, computed results for the characteristic mode eigenvalues, eigencurrents and eigenfields for penetrable objects have not appeared, not even in the seminal papers on the subject. In this thesis both volume and surface integral equation formulations are used to compute the characteristic modes of penetrable objects for what appears to be the first time. This opens the way for the use of characteristic mode theory in the design of antennas made of penetrable material whose polarization current densities constitute the main radiating mechanism of the antenna. Volume formulations are shown to be reliable but computationally burdensome. It is demonstrated that surface formulations are computationally more efficient, but obtrude some non-physical modes in addition to the physical ones. Fortunately, certain field orthogonality checklists can be used to provide a straightforward means of unambiguously selecting only the physical modes. The sub-structure characteristic mode concept is extended to problems involving both perfectly conducting and penetrable materials. It is also argued that sub-structure modes can be viewed as characteristic modes that implicitly use modified Green’s functions, but without such Green’s functions being needed explicitly. This makes the concept really practical, since the desired modified Green’s functions are not known explicitly in most cases.

description: This thesis proposes a new chroma keying method that can automatically detect background, foreground, and unknown regions. For background color detection, we use K-means clustering in color space to calculate the limited number of clusters of background colors. We use spatial information to clean the background regions and minimize the unknown regions. Our method only needs minimum inputs from user. For unknown regions, we implement the alpha matte based on Wang's robust matting algorithm, which is considered one of the best algorithms in the literature, if not the best. Wang's algorithm is based on modified random walk. We proposed a better color selection method, which improves matting results in the experiments. In the thesis, a detailed implementation of robust matting is provided. The experimental results demonstrate that our proposed method can handle images with one background color, images with gridded background, and images with difficult regions such as complex hair stripes and semi-transparent clothes.

description: Le transfert des compétences représente l’enjeu principal de tout programme de formation à l’enseignement. Les compétences professionnelles développées pendant la formation initiale trouvent leur contexte de transfert durant le stage. Toutefois, les novices en enseignement font face à de nombreuses difficultés. Cette recherche qualitative avait pour objectif d’étudier ce processus à partir des déclarations de dix étudiants stagiaires du Centre de Formation pour l’Enseignement Fondamental (CFEF) de Martissant en Haïti. Un schéma d’entrevue semi-dirigée était adressé aux participants et portait sur les compétences transférées par les stagiaires en planification de l’enseignement, en gestion des apprentissages, sur la place de la pratique réflexive, les défis rencontrés dans ce processus et les moyens utilisés pour les surmonter. Les résultats ont permis d’identifier des types de défis ayant rapport avec les domaines de compétence choisis pour une prise en compte des retombées de nombreux facteurs sur le processus de transfert dont notamment l’expérience de la pratique réflexive.

description: This study examines phrase and larger formal structures in the first movement of Leo Brouwer’s Elegio de la Danza (1964), a work that draws on tonal and post-tonal traditions. By adapting key features of the tonal motive, as described by Douglass Green, and the tonal period, as proposed by Green and William Caplin, the model seeks to provide a tool for the discussion of phrases and larger forms in Brouwer’s work. An analysis of primary parameters, such as melody, harmony, and rhythm, provides the means to discuss how the composer articulates beginnings and endings of statements and responses, which are then grouped into antecedent and consequent phrases. These periods articulate large-scale sections, which outline a ternary formal design. Secondary parameters (dynamics, tempo markings, instrumental markings) further contribute to the identification of formal structures in Brouwer’s work.
