▼ Diseases such as Alzheimer’s, Parkinson’s, eye lens
cataracts, and Type 2 diabetes are the results of protein
aggregation. Protein aggregation is also a problem in
pharmaceutical industry for designing protein based drugs for long
term stability. Disordered states such as precipitates and gels and
ordered states such as crystals, micro tubules and capsids are both
possible outcomes of protein–protein
interaction. To understand the
outcomes of protein–protein
interaction and to find the ways to
control forces, it is required to study both kinetic and
equilibrium factors in protein–protein interactions. Salting
in/salting out and Hofmeister effects are familiar terminologies
used in protein science field from more than a century to represent
the effects of salt on protein solubility, but they are yet to be
understood theoretically. Here, we build a theory accounting both
attractive and repulsive electrostatic interactions via the Poisson
Boltzmann equation, ion–protein binding via grand cannonical
partition function and implicit ion–water
interaction using
hydrated ion size, for describing salting in/salting out phenomena
and Hofmeister and/or salt specific
effect. Our model free energy
includes Coulomb energy, salt entropy and ion–protein binding free
energy. We find that the salting in behavior seen at low salt
concentration near the isoelectric point of the protein is the
output of Coulomb energy such that the addition of salt not only
screens dipole attraction but also it enhances the monopole
repulsion due to anion binding. The salting out behavior appearing
after salting in at high salt concentration is due to a salt
mediated depletion
interaction. We also find that the salting out
seen far from the isoelectric point of the protein is dominated by
the salt entropy term. At low salt, the dominant
effect comes from
the entropic cost of confining ions within the aggregates and at
high salt, the dominant
effect comes from the entropy gain by ions
in solution by enhancing the depletion attraction. The ion size has
significant effects on the entropic term which leads to the salt
specificity in the protein solubility. Crystal growth of
anisotropic and fragile molecules such as proteins is a challenging
task because kinetics search for a molecule having the correct
binding state from a large ensemble of molecules. In the search
process, crystal growth might suffer from a kinetic trap called
self–poisoning. Here, we use Monte Carlo simulation to show why
protein crystallization is vulnerable to the poisoning and how one
can avoid such trap or recover crystal growth from such trap during
crystallization. We show that self–poisoning requires only three
minimal ingredients and these are related to the binding affinity
of a protein molecule and its probability of occurrence. If a
molecule attaches to the crystal in the crystallographic state then
its binding energy will be high but in protein system this happens
with very low probability (≈ 10−5). On the other hand,
non–crystallographic binding is energetically weak, but it…

▼ Estimating nonlinear effects, including
interaction and quadratic effects, is a prevailing issue in social and behavioral science. Despite several advantages of using latent variable models in estimating nonlinear effects, conducting path models with observed composites is still a very common practice among applied researchers. However, it is well-known among methodologists that conducting path models without considering the measurement errors of the observed composites would lead to biased estimation. Hence, the aim of this dissertation is to bridge the gap between methodologists and applied researchers by reviewing two methods— reliability adjusted product indicator (RAPI) and latent moderate structural equations (LMS)—which can be applied for estimating nonlinear effects while accounting for the measurement errors of the composites.
The dissertation is composed of three manuscripts. In the first manuscript I reviewed the RAPI and LMS methods and compared their performance with the conventional path models in terms of the estimation accuracy of the
interaction effects. The second manuscript focuses on choosing the most appropriate reliability estimates while conducting the RAPI and LMS methods. In the third manuscript I discuss issues regarding having both
interaction and quadratic effects in the models, and the impact of multicollinearity of the exogenous variables on the estimation of both nonlinear effects.
Based on the simulation results, I found that while estimating nonlinear effects with observed composites, conduct latent variable models and apply both the RAPI and LMS methods yielded more accurate
interaction estimates than the conventional path analysis. Additionally, for items following congeneric assumption, applying the RAPI and LMS methods with the Revelle’s omega total yielded more accurate results; if only the power of the test is of interest, applying Cronbach’s alpha, omega, and GLB make less difference. However, caution should be made for applying the RAPI and LMS methods when the correlation between the latent exogenous variables are high (i.e., over .5), especially when both
interaction effects and quadratic effects are of interest. This dissertation concludes with a summary of findings and the implications of these findings in applied research.

▼ Rule induction is a popular technique for knowledge acquisition and data mining. Many techniques, such as ID3, C4.5, CART (tree induction tecniques) and Artificial Neural Networks have been developed and widely used. However, most techniques are either based on categorical or numerical mechanisms to assess the importance of different input variables, which may not produce the optimal rule when a mixture of variables exists.
In 1992, Liang proposed a composite approach called CRIS that use different method to analyze different types of data in inducing rules for binary classification. Yang conducted a follow-up research to extend the original algorithm to multiple categories. However, both methods do not take variable
interaction into consideration.
The purpose of this research is to extend previous approach and extend by including second-order
interaction. We also take into consideration the kurtosis and skewness of data for numerical variables. For categorical data, we also adopt ID3 algorithm to handle classes with low representation in the sample. In order to evaluate this technique, we develop a prototype CRIS 3.0 and compare with existing techniques, including multi-category-CRIS, CART and C4.5 as benchmark. The results show that CRIS 3.0 has the highest probability of producing the highest prediction accuracy.

Scale Interaction and Mid-latitude Atmospheric Predictability: Impacts of Moist Convection and Gravity Waves.

▼ The small-scale processes (e.g., convective cells and gravity waves) that are often not fully resolved and represented by our forecast models, will affect processes at well-resolved scales and increase the uncertainties in our predictions. This thesis examines the scale interactions in predictability experiments using convection-permitting high-resolution ensembles of both global and regional scales, in order to study the intrinsic and practical predictability limit of in our numerical weather forecast.
The first part of this dissertation is aimed at testing Zhang, Snyder and Rotunno’s three-stage error growth hypothesis focusing on the role of moist convection in the upscale error growth behavior. In the dry experiment free of moist convection, error growth is controlled primarily by baroclinic instability, hence forecast accuracy is inversely proportional to the amplitude of the baroclinically unstable initial condition error. Therefore, the accuracy of the prediction can be continuously improved without limit through reducing the initial error. On the contrary, in a moist environment with strong convective instability, rapid upscale growth arises from moist convection. As a result, the forecast error becomes increasingly less sensitive to the scale and amplitude of the initial perturbations. These diminishing returns from more accurate initial conditions may ultimately impose a finite-time barrier to the forecast accuracy. Moreover, the inclusion of strong moist convection changes the mesoscale (wavelength smaller than 500 km) kinetic energy spectrum slope from −3 to approximately −5/3 in our simulations, which is consistent with observations. Since the error spectrum will adjust toward the slope of the background flow, this change in slope of the background flow in our simulations due to moist convection further highlights the importance of moist convection to both the intrinsic and practical limits of atmospheric predictability, especially at meso- and convective scales.
Building upon the finding of the kinetic energy slope, in part two of this dissertation, it is further demonstrated that convective systems, triggered in a horizontally homogeneous environment, are able to generate a background mesoscale kinetic energy spectrum with a slope close to -5/3. To investigate the processes that are responsible for generating the -5/3 slope, spectral kinetic energy budget analysis is performed. The analyses show that the buoyancy production generated by moist convection, while mainly injecting energy in the upper troposphere at small scales, could also contribute to larger scales. The injected energy is then transported by energy fluxes (due to gravity waves and/or convection) both upward and downward. Nonlinear interactions, associated with the velocity advection term, finally helps build the approximate “-5/3” slope through upscale/downscale propagation of the energy at all levels.
The last part of the dissertation focuses on the influence of the upscale error growth to the operational forecast and the…

▼ Availability of data with hundreds of variables in the current era, emphasizes on the impor- tant of feature selection methods. Feature selection methods reduces computation time, improves prediction performance, and helps a better understanding of the data in the machine learning applications.
The main topic of this dissertation is developing new feature selection algorithms for data sets with continuous or binary response with consideration of feature interaction. Based on the literature, discovering interaction effect is a notoriously challenging task. In the first paper, we proposed a first optimization approach that can detect interacting features and the exact combination of these variables. The method was applied on a simulation experiment of the soybean data set and showed a %95 chance of correctly detecting second-order to fifth-order interaction effects between genes. The second paper discussed the importance of considering interacting features in feature selection. We developed a novel feature selection method for data sets with continuous response variables and established a computational framework for selecting a subset of features with significant main effects and a subset of features with significant interaction effects. And finally in the third paper, we expand our method for data sets with binary response and proposed a feature selection model that classifies two finite point sets in n-dimensional features space with consideration of feature interaction. Methods were applied on on the publicly available real-world databases and showed improvements in prediction analysis.

▼ Vanadates oxide materials exhibit a variety of functional properties whose origin is closely related to the structural and electronic peculiarities of the compounds. Recently, in the vanadatesTM2V2O7 (TM = Cu, Co and Ni), a magnetically driven ferroelectric phenomena has been reported. The multiferroic ordering of these system closely connected with the crystal structure and their magnetic properties. The crystallographic structure for Co2V2O7 exhibits a dichromate structure with crystallizes in a monoclinic symmetry, whereas Cu2V2O7 crystallizes in two different polymorphs (I) α-structure, that is orthorhombic and noncentrosymmetric, and the (II) ï¢-phase that is monoclinic and centrosymmetric. In Co2V2O7, two Co2+O6 cations octahedral connected via edge sharing and forms the zigzag chains along c-axis and chains are separated by nonmagnetic (V2O7)4- groups that lead to frustrated one dimensional antiferromagnetic ordering. On the other hand, in α-Cu2V2O7, Cu2+O5 polyhedral form the cross-linking chain network which are separated by (V2O7)4- anion units makes system a weak ferromagnet ground state induced by Dzyaloshinskii-Moriya (DM)
interaction. In these present study, we are doping the small concentration (5%) of magnetic (Co) and nonmagnetic (Zn and Ga) elements to understand the
effect of doping on the structural magnetic and dielectric properties of α-Cu2V2O7. Our magnetization data clearly indicates that the Co doping significantly modifies the ground state magnetic property by invoking the frustration. However nonmagnetic elements does not show much influence on the strength of DM
interaction of α-Cu2V2O7. We believe local structural modulation by chemical doping with different doping element might alters the magnetic ground state of α-Cu2V2O7.

▼ The activities of humans in the marine environment are on a steady rise; this trend follows the exposure of offshore structures and vessels to harsh environmental conditions. On the other hand, there is continuous demand for lighter, faster and more efficient vessels. Technological advancement in composite materials and better design methods invariably leads to more sophisticated computational tools. In these tools, the inherent flexibility of the structure is involved in the calculation of its loading and response – introducing the aspect of fluid-structure
interaction. However, more than fluid-structure
interaction, hydroelasticity which is a subset of fluid-structure
interaction allows for deformation of the structures due to fluid. Current industry practice neglects these deformations and all structures are designed as rigid bodies. These practices lead to overestimation of the frequency which translates to the mass and how stiff the structure is. Design based on hydroelasticity allows for knowing the true behaviour of the structure; thus, a coupling of fluid and structure yields a true appreciation of these designs. The objective of this study is to formulate and solve analytically the coupling phenomenon behind fluid-structure
interaction. An experiment designed by Lampros Rizos in 2016 which modelled fluid-structure
interaction consisted of a set-up with a cylinder immersed in a larger cylindrical tank. The immersed cylinder having a flexible circular membrane (structure) located at its bottom. The cylinders were filled with non-viscous liquid and exhibited free surface. The designed experiment was decoupled and a systematic build up in understanding the dynamics of all components – structure and fluid were solved. Firstly, the dynamics of the structure when dry (In vacuo) was idealized in 2-D and 3-D. Secondly, the system was coupled and solved in 2-D and 3-D when structure is located at the top and bottom of a single cylinder individually. The use of a series solution: Fourier-Cosine and Fourier-Bessel series solutions were used for 2-D and 3-D cases respectively. Along with these series solutions, the fluid governing equations were employed to solve for the coupled frequencies. Lastly, the entire submerged structure was analysed and solved. The hydroelastic or coupled frequencies and vibration patterns are determined for lower angular and radial modes for which the influences of various parameters are investigated. A trend was observed – that for lower modes, the hydroelastic frequencies are lower than individual membrane natural frequencies at low frequencies. At higher frequencies, the coupling effects are larger making the coupled frequency higher than uncoupled frequencies. There is a strong relationship between the tension of the membrane and the hydroelastic frequencies. An increase in the tension causes an increase in the hydroelastic frequencies. Also, the hydroelastic frequencies increase as the fluid depth increases. More so, the increase in fluid depth tends to converge towards the…

▼ Klotsapiini on tehokkain psykoosilääke muille psykoosilääkkeille hoitoresistentissä skitsofreniassa. Klotsapiinilla on aggressiivisutta sekä itsetuhoisuutta vähentävä vaikutus. Sen käyttöä rajoittavat kuitenkin lukuisat sivuvaikutukset, joista tunnetuin on agranulosytoosi. Myös klotsapiinin aiheuttamien myokardiiti, aspiraatiopneumonia, ileus sekä painon nousu voivat olla hengenvaarallisia ja ne voivat aiheuttaa enemmän kuolemantapauksia, kuin agranulosytoosi. Klotsapiinin käyttöön liittyvä granulosytopenia ja agranulosytoosi sekä sydäntulehdus voivat edellyttää klotsapiinihoidon välitöntä keskeyttämistä, jolloin psykoosin uusiutumis- ja pahenemisriski ovat suuria. Klotsapiinin käyttöön liittyy myös monia muita epämiellyttäviä hoitoa haittaavia sivuvaikutuksia, joita ovat esimerkiksi sedaatio, syljenerityksen lisääntyminen ja kouristuskynnyksen aleneminen.
Klotsapiinilla on paljon yhteisvaikutuksia esimerkiksi muiden lääkkeiden kanssa. Se metaboloituu pääosin maksan sytokromijärjestelmän ja erityisesti CYP1A2:n kautta, joiden kautta monet lääkeaineet ja esimerkiksi tupakointi voivat vaikuttaa klotsapiinin metaboliaan.
Ensimmäisessä osatyössä tutkittiin retrospektiivisesti äkillisen klotsapiinihoidon lopettamisen vaikutusta psykoosioireisiin kun lääkitys jouduttiin lopettamaan ilman potilaasta johtuvaa syytä. Aineiston muodostivat 28 Pitkäniemen sairaalassa hoidettua skitsofreniapotilasta, joiden klotsapiinilääkitys lopetettiin heinäkuussa 1975, kun klotsapiinin käyttö kiellettiin Lääkintöhallituksen määräyksellä kahdeksen klotsapiinihoitoa saaneen potilaan menehdyttyä agranulosytoosiin. Lopettamisen seurauksena psykiatriset oireet lisääntyivät nopeasti noin puolella potilaista. Oireiden lisääntymisen todennäköisyyttä vähensi antikolinergisen lääkityksen tai muun psykoosilääkkeen käyttö. Toisessa osatyössä tutkittiin tupakoinnin vaikutusta seerumin klotsapiinipitoisuuteen 44 sairaalahoidossa olevalla potilaalla. Tupakoivien potilaiden seerumin klotsapiinipitoisuudet olivat merkitsevästi matalampia (38 %) kuin tupakoimattomien potilaiden. Tupakoivilla potilailla oli tilastollisesti merkitsevästi suuremmat painoon suhteutetut klotsapiiniannokset, vaikka heidän seerumin klotsapiinipitoisuutensa oli pienempi.
Kolmannessa ja neljännessä osatyössä käytettiin samaa kolmen sairaanhoitopiirin alueelta kerättyä 237:n klotsapiinipotilaan aineistoa. Kolmannessa osatyössä tutkittiin klotsapiinin subjektiivisia sivuvaikutuksia LUNSERS-itsearviointilomaketta käyttäen. Monimuuttuja-analyysissä todettiin yhteys seerumin klotsapiinipitoisuuden ja ilmoitettujen masennus-ahdistussivuvaikutuksen, nuoremman iän ja lääkityksestä koetun sedaation sekä lisääntyneen unien näkemisen välillä. Lisäksi psykoosilääkkeiden yhdistelmiä käyttävät potilaat raportoivat enemmän sympatikotonia-tensio -tyyppisiä oireita.
Neljännessä osatyössä tutkittiin tupakoinnin ja painoindeksin välistä suhdetta klotsapiinihoitoa saavilla potilailla. Tupakoivien ja tupakoimattomien potilaiden painoindekseissä ei todettu eroa toisin kuin aiemmissa, normaaliväestöä…

▼ Anthropomorphism is a common phenomenon when people attribute human characteristics to non-human objects. It plays an important role in acceptance of robots in natural human environments. Various studies in the field of Human-Robot Interaction (HRI) show that there are various factors that can affect the extent to which a robot is anthropomorphized. However, our knowledge of this phenomenon is segmented, as there is a lack of a coherent model of anthropomorphism that could consistently explain these findings. A robot should be able to adjust its level of anthropomorphism to a level that can optimize its task performance. In order to do that, robotic system designers must know which characteristics affect the perception of robots' anthropomorphism. Currently, existing models of anthropomorphism emphasize the importance of the context and perceiver in this phenomenon, but provide little guidelines regarding the factors of a perceived object that are affecting it.
The proposed reverse process to anthropomorphization is known as dehumanization. In the recent years research in social psychology has found which characteristics are deprived from people who are perceived as subhumans or are objectified. Furthermore, the process of dehumanization is two dimensional rather than unidimensional. This thesis discusses a model of anthropomorphism that uses characteristics from both dimensions of dehumanization and those relating to robots' physical appearance to affect the anthropomorphism of a robot. Furthermore, involvement of implicit and explicit processes in anthropomorphization are discussed.
In this thesis I present five empirical studies that were conducted to explore anthropomorphism in HRI. Chapter 3 discusses development and validation of a cognitive measurement of humanlikeness using the magnitude of the inversion effect. Although robot stimuli were processed more similarly to human stimuli rather than objects and induced the inversion effect, the results suggest that this measure has limited potential for measuring humanlikeness due to the low variance that it can explain. The second experiment, presented in Chapter 4 explored the involvement of Type I and Type II processing in anthropomorphism. The main findings of this study suggest that anthropomorphism is not a result of a dual-process and self-reports have a potential to be suitable measurement tools of anthropomorphism.
Chapter 5 presents the first empirical work on the dimensionality of anthropomorphism. Only perceived emotionality of a robot, but not its perceived intelligence, affects its anthropomorphization. This finding is further supported by a follow up experiment, presented in Chapter 6, that shows that Human Uniqueness dimension is less relevant for a robot's anthropomorphiazability than Human Nature (HN) dimension. Intentionality of a robot did not result in its higher anthropomorphizability. Furthermore, this experiment showed that humanlike appearance of a robot is not linearly related with its anthropomorphism during HRI. The lack of…

▼ Les canopées sont des assemblées compactes de plantes dont l'étude concerne de nombreuses problématiques environnementales. Des applications technologiques sont également envisageables. Les précédents travaux se sont principalement focalisés sur les écoulements au-dessus des canopées, considérées comme des rugosités de fond. La présence d'un point d'inflexion dans le profil de vitesses dans le fluide autorise le développement d'instabilités de type couche de mélange à l'interface. De plus, la prise en compte de la flexibilité des plantes complique le problème, car leur forme est modifiée par le courant pour réduire la traînée exercée sur elles – c'est le phénomène de reconfiguration – mais elles ont également une dynamique propre qui peut éventuellement influencer l'écoulement. La démarche envisagée dans cette thèse est essentiellement expérimentale. Elle cherche à comprendre la réaction des tiges à différents types d'écoulements, afin d'étudier les effets collectifs inhérents à la canopée, et d'identifier les mécanismes communs qui en sont à l'origine. On utilise pour cela des tiges modèles très simples dans un canal étroit, ce qui assure une configuration quasi 2D et facilite les observations. Dans un premier temps, on étudie la réaction statique de la canopée à un écoulement établi. L'effet de la densité est très clair tant que les plantes sont assez proches, sinon elles se comportent comme si elles étaient seules. Ensuite, la canopée est soumise à un écoulement oscillant (houle), et, de la même façon, on étudie la différence de réaction entre une tige seule et une tige incluse dans une canopée. La troisième partie s'intéresse à la dynamique de la canopée soumise à un écoulement unidirectionnel, permettant le développement d'instabilités au sommet de la canopée. Le régime de grandes ondulations cohérentes de la canopée, apparenté au ‘monami' de la littérature, est caractérisé
Vegetation in rivers is often considered as a source of water resistance which slows down the water conveyance. It is also one of the main component for river equilibrium, insofar as it prevents body erosion by providing bed stabilization, it plays a vital role during floods. It is crucial for sediment transport, water quality and also shelter to provide the necessary habitat for the biodiversity of aquatic species. It is then useful to understand the mechanical behaviour of aquatic canopies resulting from the interaction between vegetation and a water flow. From land-use planning to river management, such a knowledge would also shed light upon plant biomechanics and improve bio-inspired engineering.Traditionally, studies on aquatic vegetation explored its influence on flow properties, like velocity distribution, wake dynamics, turbulence, water conveyance and sediment transport by considering it simply as a rigid or flexible roughness element.This thesis is an experimental work which aims at understanding how a model canopy reacts to a water flow depending on the canopy geometry and the flow conditions. Three different series of…

▼ Ce travail de thèse est dédié à l'étude des effets induits sur des matériaux à effet magnétocalorique géant par impact d'ions lourds. Ces matériaux présentent une transition de phase de premier ordre liée à une forte variation d'entropie potentiellement exploitable pour le développement de systèmes de réfrigération magnétique efficaces. En contrepartie la présence d'une hystérésis thermique et la faible gamme de température utile limitent leur potentiel. Dans ce travail, nous avons exploité les effets spécifiques de l¿impact des ions lourds à basse vitesse pour modifier ces caractéristiques, en engendrant du désordre et en créant des défauts ponctuels. Dans les couches minces d'arséniure de manganèse, qui possèdent une transition de phase magnéto-structurale, nous avons montré que ces défauts agissent comme des centres de nucléation et suppriment l'hystérésis thermique de façon stable dans le temps. En faisant varier les conditions d'irradiation, nous avons pu dégager le rôle fondamental de la densité de collisions élastiques induites par ces irradiations. Les effets des ions sur des couches minces de FeRh, un autre matériau à effet magnétocalorique géant présentant une transition de phase de type métamagnétique, ne permettent pas de supprimer l'hystérésis ce qui souligne l'importance de la présence d¿un changement de phase structurale dans le processus de suppression de l'hystérésis. Par ailleurs, nos investigations révèlent que le contrôle du nombre d'ions par unité de surface impactant l'échantillon permet de moduler la température de transition de phase. Cet effet constitue une nouvelle méthode prometteuse pour les applications.
This work aims to study the effects of slow heavy ions on giant magnetocaloric materials. These materials present a first order phase transition coupled to a strong variation of entropy potentially exploitable for the development of systems of effective magnetic refrigeration. On the other hand, the thermal hysteresis and the small range of working temperatures restrict the use of these materials. In this work, we exploited the specific effects of slow heavy ions impact to modify these characteristics. Ion collisions induce disorder and point-like defects into materials. In manganese arsenide thin films, presenting a magneto-structural transition, we demonstrated that this new defects act like nucleation centers which suppress the thermal hysteresis in a stable way in time. By varying irradiation conditions, we were able to highlight the fundamental role of the density of elastic collisions generated by these irradiations. Effects of ions in iron-rhodium thin films, another giant magnetocaloric material with a metamagnetic phase transition were also studied. In this case, the thermal hysteresis is not suppressed by the ions impact indicating that the phase structural change plays an important role in the reduction of the thermal hysteresis. Furthermore our investigations demonstrated that by controlling irradiation conditions, in particular the number of incident ions on a given sample…

▼ I samband med åldrandet ses ofta en försämring av människors kognitiva förmågor, däribland det episodiska minnet, vilket är avgörande för vardagligt fungerande och livskvalitén för äldre. Livsstilsfaktorer som fysisk aktivitet (FA) och övervikt har tidigare kopplats till hälsosamt åldrande och visat sig påverka graden av försämring. Hur FA och övervikt interagerar på lång sikt för att påverka det episodiska minnet för äldre behöver dock fortfarande utredas. Denna studie undersökte både de enskilda effekterna av FA och övervikt på det episodiska minnet, samt hur dessa faktorer interagerar på lång sikt. Därtill undersöktes skillnader mellan sjuka och friska äldre deltagare. Data från deltagare (n = 5 287) i the English Longitudinal Study on Aging i åldrarna 50 och äldre användes i ett longitudinellt upplägg. Självskattade mått på FA och viktstatus från en tidpunkt användes för att predicera poäng på ett minnestest vid en tidpunkt fyra år senare, med och utan kontrollvariabler. Statistiskt signifikanta effekter av FA på minne kunde ses både med och utan kontrollvariabler, men tydliga effekter av övervikt kunde inte ses. Interaktioner mellan övervikt och FA kunde endast upptäckas i modeller utan kontrollvariabler, och inte alls i modeller med enbart sjuka deltagare. Slutsatser om överviktens påverkan på det episodiska minnet kunde inte dras, men resultatet ger vidare stöd till att FA hjälper till att bevara minnet i åldrandet. Sammantaget förklarades dock mer av variansen i episodiskt minne av kontrollvariabler som ålder och utbildningsnivå.
With aging often comes declining cognitive function, with episodic memory being one of the declining factors crucial for everyday functioning and quality of life among the elderly. Lifestyle factors such as physical activity (PA) and overweight have been associated with healthy aging and the trajectory of the decline. How PA and overweight interact in affecting episodic memory over time among the elderly is, however, still in need of further investigation. The present thesis investigated both the direct effects of PA and overweight on episodic memory, and how the interaction between these factors affect episodic memory. Furthermore, differences in the effects between participants with or without illnesses were examined. Data from participants (n = 5 287) in the English Longitudinal Study on Aging aged 50 and older were used in a longitudinal design. Self-reported measures of PA as well as measures of weight- status from time point 1 was used to predict scores on a memory test at a second time point, four years later, with and without control variables. Statistically significant effects of PA on memory score were detected, both with and without control variables. No statistically significant effects of overweight were detected. Interactions between overweight and PA could only be detected in models without control variables, and not at all among participants with illnesses. Conclusions on the effect of…

▼ Modelos de Simulador de Manobras de Navios em Tempo Real vem se tornando cada vez mais comuns e necessários na análise de viabilidade de portos e canais de acesso. O aumento do porte das embarcações, não acompanhado por equivalente aumento das dimensões dos portos, faz com que cada vez mais os efeitos de águas rasas e interação com margens e estruturas portuárias se tornem relevantes durante uma manobra. Com o intuito de aumentar a gama de aplicação desse tipo de simulador, o presente trabalho aborda uma modelagem matemática para estimar as forças hidrodinâmicas de interação com as margens e outros navios para aplicação em simuladores de manobras. O modelo usa, como base, dados oriundos de um método numérico validado experimentalmente, o Método dos Elementos de Contorno. Baseado nesse método, alguns casos tipo foram selecionados para gerar um banco de dados e um modelo matemático foi desenvolvido para estimar as forças de interação, extrapolando as
respostas obtidas para casos não previstos anteriormente. A obtenção das forças através do modelo é baseada em alguns parâmetros de entrada, tais como velocidade de avanço da embarcação e as distâncias relativas entre o navio e o meio. Assim, aplica-se uma série de medidas para determinar geometrias aproximadas do meio e/ou posição de outros navios em um dado instante. Foi realizada uma verificação do modelo para casos não previstos, avaliando os erros associados à modelagem e sua aplicabilidade. Os erros foram considerados aceitáveis para as condições impostas, visto as aplicações existentes em simuladores de manobras. Além disso, o modelo desenvolvido foi executado no simulador de manobras, no qual foram realizados alguns testes de sensibilidade ao movimento, além de algumas comparações com outros trabalhos, quando possível.
Real-time Ship Maneuvering Simulator models are becoming more common and necessary in the feasibility analysis of ports and access channels. The constant
increase in the length and draught of vessels, not followed by equivalent ports development, makes the effects of shallow water, ship-bank and ship-port interaction with other structures more relevant during a maneuver. In order to increase the application range of this kind of simulator, the present work develops a mathematical model to estimate ship-bank and ship-ship hydrodynamic interaction forces and moments during a maneuver. The model uses, as a reference, data derived from an experimentally validated numerical method, the Boundary Element Method (BEM). Based on this method, some reference cases were selected to generate a database which would be used by our mathematical model to extrapolate results and estimate the interaction forces for any unexpected scenario. The forces obtained through the model are based on some input parameters, such as the vessel forward speed and the relative distances between the ship and bank and other ships. Thus, a series of measurements were
developed to determine approximate geometries of the port and/or position of other ships at a given time slot.…

▼ Physics
The quantum interference effects, such as the Autler-Townes (AT) effect and electromagnetically induced transparency (EIT) applied to molecular systems are the focus of this Dissertation in the context of high resolution molecular spectroscopy. We demonstrate that the AT effect can be used to manipulate the spin character of a spin-orbit coupled pair of molecular energy levels serving as a it{gateway} between the singlet and triplet electronic states. We demonstrate that the singlet-triplet mixing characters of the it{gateway} levels can be controlled by manipulating the coupling laser it{E} field amplitude. We observe experimentally the collisional population transfer between electronic states G1Πg (v=12, J=21, f) and 13Σ g-(v=1, N=21, f) of 7Li2. We obtain the Stern-Vollmer plot according to the vapor pressure dependence of collisional transfer rate. The triplet fluorescence from the mixed it{gateway} levels to the triplet b3Πu(v'=1,J'=

▼ In this thesis, we study coherent delocalization in the light-matter interaction: we investigate
how the coherent center of mass delocalization of a first quantized system affects its interaction
with a second quantized field. We develop a suitably generalized Unruh-DeWitt model for the
interaction between a delocalizing particle and a relativistic quantum field. We discuss the
impact which the coherent spreading of the detector's center of mass wave function has on the
simple processes of absorption, spontaneous emission and vacuum excitation. We find that the
dynamical virtual delocalization process leads to interesting new phenomenology not only for the
interaction of matter systems with the electromagnetic quantum field, but also with other fields
such as a phonon field. For instance, we predict that in a medium, in the case of a supersonic
coherent spreading of the center of mass wave function, a coherently delocalized detector may
get excited and emit Cherenkov-like radiation. We further investigate how the coherent center
of mass delocalization impacts the process of entanglement harvesting and the Unruh effect.
Subjects/Keywords: coherent delocalization; Unruh-DeWitt detector model; light-matter interaction; Cherenkov effect; entanglement harvesting; Unruh effect; relativistic quantum information

▼ L'état supraconducteur étant un condensat de paires de Cooper constitué d'électrons de moments et de spins opposés, il peut être fortement influencé par des effets de spin. Au cours de cette thèse, nous étudions l'effet d'un fort champ d'échange et d'un effet spin-orbite de type Rashba sur les propriétés supraconductrices. Dans une première partie, on étudie les effets associés à l'interaction entre supraconductivité et fort champ d'échange, se caractérisant par une transition de phase vers un état supraconducteur inhomogène découvert par Fulde, Ferrell, Larkin et Ovchinnikov (FFLO). On étudie tout particulièrement les fluctuations supraconductrices à l'approche de la transition de phase. On montre que ces fluctuations peuvent servir de révélateur à cette phase. Notamment, la capacité calorifique et la paraconductivité divergent de façon caractéristique à la transition vers un état modulé. On décrit également comment les effets paramagnétiques modifient les fluctuations de l'aimantation, annulant la réponse diamagnétique ou produisant des oscillations entre réponse para- et dia-magnétique. La seconde partie est dévolue aux jonctions supraconducteur-ferromagnétique (S/F). Dans les jonctions Josephson S/F/S, le champ d'échange donne lieu à des oscillations du courant critique en fonction de la longueur de la jonction, charactérisées par une alternance des états 0 et . On prédit une transition entre les états 0 et induite par la température, même dans la limite ballistique. Dans cette limite ballistique, on montre également que le courant de Josephson s'atténu sous la forme de lois de puissance en fonction de la longueur de la jonction, alors que le cas diffusif présente une atténuation exponentielle. On étudie ensuite la seconde harmonique de la relation courant-phase en présence d'une faible quantité d'impuretés. La dernière partie traite des effets de proximité lorsque les deux effets paramagnétique et spin-orbite sont présents dans une jonction Josephson. On montre que l'association d'une interaction Rashba et d'un champ d'échange induit un couplage direct entre les ordres magnétique et supraconducteur. En particulier, ce couplage permet de générer toute la dynamique magnétique par l'application d'une simple tension électrique.
The superconducting state being a Cooper pair condensate built on opposite spin and momentum electrons, it can be strongly influenced by any spin effect. In this thesis, we investigate the roles of strong paramagnetic and spin-orbit effects on superconducting properties. In a first part, the interplay between paramagnetic effect and bulk superconductivity is studied, leading to the modulated Fulde, Ferrell, Larkin and Ovchinnikov phase (FFLO phase). We focus on superconducting fluctuations near to the FFLO state. We show that these fluctuations can serve as a smoking gun for this phase. Noticeably, the fluctuation heat capacity and paraconductivity diverge in a characteristic way when approaching the phase transition towards a modulated state. Moreover, the fluctuation induced…

▼ We study the possible Chern insulator phase transitions in the Haldane-Rashba system. These systems could be established on single-layer graphene and realized by using the ultracold atoms. Therefore, we investigate the quantum anomalous Hall
effect in the Haldane-Rashba systm. We first describe how to construct tight-binding model Hamiltonian and obtain the Dirac points. We then show the electronic band structure and the corresponding wave functions of electrons. By using the boundary of phase transformation we study the change in Chern number in Haldane-Rashba system. Finally, we discuss the variation of Chern number values and its corresponding phase transitions.

▼ It is a generation of high technology. Our daily life is full of computing in
the aspects of work and leisure. Computing also influences on art, and now a
computer can be a new form of representation. Artists use computers to create
and show their art works, and viewers now not only view those art works but also
involve in art works through the interactivity of a computer.
Motion graphics are attractive. Flash based programs are rich in
interaction.
This project combines the two features to create a user driven art that promotes
classical music to children and of course to every one. In such an interactive and
attractive way, users enjoy the music and listen to the three world-known songs
from Saint Saëns's Carnival of Animals- Royal March of Lion, Aquarium, and
the Swan. When the music starts, by clicking the mouse, users can add motion
graphics related to the music on a computer screen.
It is a problem to figure out a way to generate pixel-based motion graphics with
Flash, which usually deals with vector images. First built are the codes, that give
this project functions of
interaction. Users can choose a song, add motion graphics
on a computer screen, pause or play the music, change the volume of the sound,
choose different color, and print out images they create. The rest are the motion
graphics, that reflect the unique theme of each song. In order to display well,
different methods are examined to generate motion graphics, including loading
FLV files exported by After Effects, and adding movie clips built in Flash, and
more.
The result shows that adding movie clips built in Flash is the best way. Other
ways result in the pixilated edges of graphics, the difficulty of making alpha
movies, or other technical problems. Having the capabilities of enabling users to
control the program and displaying motion graphics in high quality, this project
performs as a new medium introducing classical music to new generations.

▼ Hayatın her alanında olduğu gibi edebiyat alanında da farklı ulusların
edebiyatları arasındaki etkileşim kaçınılmazdır. Türk edebiyatı bağlamında
bakıldığında özellikle Tanzimat Dönemi’nde (1839-1895) çeviri aracılığı ile
yoğunlaşan genelde Batı-Türk, özelde ise Fransız-Türk edebiyatları arasındaki
etkileşim süreci dönem dönem etki derecesi ve yönü değişse de 1800’lü yılların
ortalarından bu yana süregelmiştir.
Fransız edebiyatının Türk edebiyatı üzerindeki etkisi sonucunda üretilen ilk
eserin Şinasi’nin Şair Evlenmesi adlı tiyatro eseri olması bu çalışma açısından önem
taşımaktadır. Ancak Türk Tiyatrosu üzerindeki etkiler yalnızca Fransız Tiyatrosu’ndan
yansımalar ile sınırlı kalmaz. 1970’li yıllarda, henüz 1920’lerde Alman tiyatro yazarı
Bertolt Brecht’in geliştirdiği Epik Tiyatro’nun yine çeviri yolu ile Türk oyun
yazarlarına ulaşması o dönemde başta Haldun Taner olmak üzere bir çok yazarın aynı
türde oyunlar yazması ile sonuçlanır. Aynı dönemde Türk Tiyatrosu üzerinde Absürt
Tiyatro adı altında Batı’da 1950’lerde ortaya çıkmış olan bir başka gelenek de
etkilerini göstermeye başlar.
Bu çalışma da genel olarak 1970 sonrasında Türk Tiyatrosu üzerinde Absürt
Tiyatro’nun etkilerini, özelde ise Batı’daki ilk örneklerden birebir yansımaları;
oyunlar arasındaki benzerlikler yanında sosyo-politik ve ekonomik arka plandan
kaynaklanan farklılıkları irdelemeyi amaçlamaktadır. Genel olarak 1970’li yıllardan
itibaren (neredeyse her on yılda bir gerçekleşen ihtilallerle paralel olarak) onar yıllık aralarla toplamda yedi yazarın on dört oyununun eklektik yöntemle çok boyutlu olarak
ele alındığı çalışma, farklı kültürlere ait çalışmaları benzerlik ve farklılıkları ve
bunların nedenleri bakımından karşılaştırarak Karşılaştırmalı Edebiyat Bilimi’ne de
katkı sunma çabasındadır.
Sonuç olarak, Batı edebiyatı içinde doğup gelişen Absürt Tiyatro geleneğinin
1970’li yıllardan itibaren Türk Tiyatrosu’nu yoğun olarak etkilediği; ancak oyunlar
arasında Absürt Tiyatro özellikleri bakımından benzerlikler olmasına rağmen, son
derece farklı siyasal, toplumsal ve ekonomik koşullar nedeniyle Türk tiyatro
yazarlarının eserlerinde, bazen açık bazen örtük olarak oyunların yazıldığı dönemin
arka planına ve sorunlara yer verdiği gözlenmektedir. Bunun yanısıra, Türk oyun
yazarlarının oyunlarını sadece Absürt Tiyatro özellikleri ile sınırlandırmadığı; Epik
Tiyatro, gerçeküstü özellikler, köy seyirlik oyunları gibi türler, akımlar ve teknikler ile
-tam bir ortaklık göstermese de- farklı dönemlerde oyunlara farklı şekillerde zenginlik
kattıkları ve aslında sentez oyunlar yarattıkları görülür. Bu çalışmanın Türk
Tiyatrosu’na en önemli katkısı bazı araştırmacılar tarafından “çorak ve tüketilmiş”
hatta “dönemini kapatmış” bir konu olarak görülen Absürt Tiyatro konusuna Türk
Tiyatrosu bağlamında yeni bir soluk getirmek ve bu alanda yapılacak yeni çalışmaları
teşvik etmek olacaktır.

▼ This dissertation considers questions in the econometrics of discrete games of complete information. Chapter 1 proposes an econometric framework that explicitly models the selection of equilibria as a discrete choice model. Such framework could achieve point identification. A simulation based approach is proposed to estimate the structural model. Chapter 2 discusses the relationship among the three types of partial identification approaches available in the literature. I show a modified version of bound estimation is equivalent to the sensitive analysis approach and the sharp identification approach in the sense that they draw inference on the same identified set. Chapter 3 studies identification and estimation of discrete games in large networks. Moment inequalities on choice probabilities of subnetworks are constructed to partially identify the model. Monte Carlo studies are conducted in Chapter 1 and 3 to evaluate the performance of approaches developed in this dissertation. Two applications are considered, Chapter 1 contains a study on the entry competition in the home improvement industry; Chapter 3 studies peer effects on smoking in friend networks.

▼ Energy efficiency limit has becomes the main obstacle for the power-constrained applications using the conventional silicon complementary metal-oxide-semiconductor (CMOS) technology. In particular, the supply voltage scaling has slowed down in the past few technology generations due to the 60 mV/decade fundamental limit for on-off switching, which prevents the reduction of the energy per operation in today’s circuits and systems. To mitigate this challenge, tunneling-field-
effect-transistor (TFET), as a viable alternative, has been proposed to achieve steep on-off switching at low supply voltages. Driven by the on-going progress of TFET prototype device development and its device characteristics applicable for different applications, co-design of TFET device-to-circuit is not only critical to transform the technology advantages into various application domains, but also important to evaluate its potential challenges. This dissertation has been dedicated to developing the simulation frameworks to model the III-V semiconductor material based TFETs from devices to circuits and system architectures. Based on the layers of abstractions, the impact of the steep sub-threshold slope, the asymmetrical source/drain, the uni-directional conduction as well as the digital and analog/RF metrics are explored for III-V TFETs. These unique device characteristics of TFETs are essential to enable the circuit design innovations and expand energy efficient application landscapes such as ultra-low power energy scavenging systems and body sensor nodes. Moreover, due to their low-voltage operation and the difference in the material systems and device designs, the reliability issues such as radiation induced single-event upsets, process variations as well as the parasitic effects of TFETs need to be evaluated from practical application perspectives, which are also addressed in this work.

▼ Dramatic choices are the core of the content in contemporary adventure games like those produced by Telltale Games and Dontnod Entertainment, developers of the Life is Strange series. These consist of emotionally-charged and dramatically contextualized player choices rather than strategic or skill-based challenges. Current approaches to understanding and assessing player experience in these games include surveys, interviews, think-aloud and various biometric measurements. These measures, taken alone, are useful for understanding traditional gameplay challenges such as platformers or puzzles but fall short of assessing how emotional content influences player experience or leads to variations in player responses. I collaboratively conducted a study of six players playing the first episode of The Wolf Among Us (TWAU) by Telltale Games, recording gameplay and facial expressions along with heart rate and skin conductivity. To compare and analyze player responses and classify content features, I developed an encoding, the Interactive Cinematic Experience (ICE) schemata, and used it to annotate player traversals with feature locations and player choices. These align player response data to content for comparison and analysis. Researchers can use the model to compare multiple paths through the game that can span hours of gameplay. In order to understand the dataset better, I developed a web-based visual data mining tool, Sherlock, for annotating and analyzing player experience datasets using the schemata and assessed it with a group of game researchers. I compare the encoding method to two other encodings using content from TWAU: Elson's Story Intention Graphs and Mawhorter's choice poetics. Analyzing facial expressions using ICE for the first three chapters revealed a spectrum of variations in responses to content, supporting the presence and effectiveness of emotional content anchors and the characteristics of what I call the Telltale effect. Thematic content that depended on choices differed in the values portrayed from content that was always included. The approach of using multiple player responses, especially facial expression analytics, is essential to a "medium read" of experiences and is a promising direction for interactive narrative research using existing commercial storygame content.

▼ Mestrado em Educação e Sociedade
O estudo que apresentamos analisa o caso de dois alunos com um passado de insucesso escolar e que inverteram suas trajectórias de vida escolar para o sucesso escolar. Tem como principal objectivo investigar a influência da interacção professor-aluno e as expectativas do professor – efeito Pigmalião na produção do desempenho escolar.
No processo de investigação utilizou-se a metodologia qualitativa interpretativa por se tratar de histórias de vida (re)contadas por diversos actores (aluno, pais, professores, etc). A pesquisa desenvolveu-se em duas escolas de 1º Ciclo: uma em Portugal do Ensino Básico e outra no Brasil do Ensino Fundamental, frequentadas por alunos pertencentes às classes sociais desfavorecidas.
Os dados da pesquisa foram obtidos através de uma grande diversidade de fontes: entrevistas, documentos oficiais das escolas e dos alunos, fichas de avaliação, textos escritos pelos alunos, relatórios, relatos, conversas informais e notas de trabalho de campo.
De um modo geral, verifica-se que os dois casos de estudo apresentam pontos de similitude de opinião dos intervenientes no processo ensino-aprendizagem que, embora em continentes distantes com culturas distintas, não só identificam o “efeito professor” na produção do sucesso escolar como, também, apontam para este ser um factor decisivo na transformação do aluno.
Verificou-se que a importância da relação professor-aluno que se estende à família (positivamente) e as expectativas do professor (que se reflectem no aluno e na família) contribuem para o sucesso escolar do aluno.
The study we present focuses on the cases of two students who lacked educational achievement and who were able to change their performance and to succeed. Its main goal is to analyse the implications of the teacher-student relationship and of the teacher‟s expectations – the Pygmalion effect towards the student‟s performance at school.
A qualitative and interpretative methodology was used for analysing these cases, once we were dealing with life stories told and retold by different actors (student, parents, teachers, etc.). This research was developed in two elementary schools: one in Portugal and the other one in Brazil and which are attended by students who belong to low social settings.
The data were obtained through a variety of sources: interviews, official documents from the school and from the students, assessments and texts written by students, reports, statements, informal talks and field study notes.
In a general way, these two study cases show points of similarity in what concerns the interveners‟ opinion on the teaching and learning process. Although they live in distant continents with different cultures, they have not only identified “the teacher‟s effect” in their educational achievement at school but they have also mentioned it as a decisive factor for the student‟s transformation,
It is clear that the importance of the teacher-student relationship which is seen in the family (in a positive way) and of the teacher‟s expectations…

▼ The thesis is a country-level study on the institutional and human capital determinants of growth-aspiration entrepreneurial activity. By using country-level panel-data analysis, the study is to our knowledge the first to test to what extent country-level human capital accumulation is associated with the prevalence of growth-aspiration entrepreneurship. Overall findings of the study suggest that there are different effects of the institutional determinants on the prevalence of growth-aspiration entrepreneurship in developing countries and developed countries. The study also found that country-level human capital moderates the effects of the institutional environment.

▼ To help mitigate the escalating prevalence of Type 2 Diabetes (T2D) and alleviate society of its associated morbidity and economic burden on health care, it is crucial to understand its aetiology. Both genetic and the environmental risk factors are known to be involved. Healthy diets have been proven to reduce the risk of T2D in primary prevention trials, however, which components and exact mechanisms are involved is not fully understood, in particular, the role of macronutrient intake. Body weight, glycaemic markers and T2D are all to some extent genetically regulated. There may also be genetic influences on how people digest, absorb or metabolise macronutrients. This poses the possibility that the interplay between genes and our diet may help us unravel T2D’s aetiology.
The aim of this PhD was to investigate gene-diet interactions on the risk of incident T2D, focusing primarily on macronutrient intake as the dietary factor. First, I systematically evaluated the current evidence before taking a step-wise approach (hypothesis driven to hypothesis-free) to interrogate gene-macronutrient interactions. This identified 13 publications, with 8 unique interactions reported between macronutrients (carbohydrate, fat, saturated fat, dietary fibre, and glycaemic load derived from self-report of dietary intake and circulating n-3 polyunsaturated fatty acids) and genetic variants in or near TCF7L2, GIPR, CAV2 and PEPD (p<0.05) on T2D. All studies were observational with moderate to serious risk of bias and limitations that included lack of adequate adjustment for confounders, lack of reported replication and insufficient correction for multiple testing.
Second, these reported interactions did not replicate in a large European multi-centre prospective T2D case-cohort study called EPIC-InterAct. We concluded that the heterogeneity between our results and those published could be explained by methodological differences in dietary measurement, population under study, study design and analysis but also by the possibility of spurious interactions.
Third, given the paucity of gene-macronutrient interaction research using genetic risk scores (GRS), we examined the interaction between three GRS (for BMI (97 SNPs), insulin resistance (53 SNPs) and T2D (48 SNPs)) and macronutrient intake (quantity and quality indicators) in EPIC-InterAct. We did not identify any statistically significant interactions that passed multiple testing corrections (p≥0.20, with a p value threshold for rejecting the null hypothesis of 0.0015 (based on 0.05/33 tests)). We also examined 15 foods and beverages identified as being associated with T2D, and no significant interactions were detected. Lastly, we applied a hypothesis-free method to examine gene-macronutrient interactions and T2D risk by using a genome-environment-wide-interaction-study. Preliminary findings showed no significant interactions for total carbohydrate, protein, saturated fat, polyunsaturated fat and cereal fibre intake on T2D.
In conclusion, the consistently null findings in this…

▼ Charged particle dynamics can be altered considerably even by weak electromagnetic waves if some of the particles are in resonance. Depending on the wave parameters, the resonances in the phase space can either be well separated, in which case the particle dynamics is regular almost everywhere, or they can overlap leading to stochastic particle motion in a large volume of the phase space. Although different, both of these regimes allow one to manipulate particle ensembles by arranging resonant interactions with appropriate waves.
This thesis is devoted to studying two wave-particle manipulation techniques having potential applications in fusion and laser-plasma
interaction research. Specifically, we study the alpha-channeling
effect (which relies on stochastic diffusion of resonant particles) and the so-called negative-mass
effect (NME) (which involves the conservation of the adiabatic invariant).
The alpha-channeling
effect entails the use of radio-frequency waves to expel and cool high-energetic alpha particles born in a fusion reactor; the device reactivity can then be increased even further by redirecting the extracted energy to fuel ions. Recently, the alpha-channeling technique, originally proposed for tokamaks, was shown to be suitable for application in mirror machines as well. In the first part of this thesis, we deepen the understanding of issues and possibilities of the alpha-channeling implementation in open-ended reactors. We verify the feasibility of this technique and identify specific waves and supplementary techniques, which can potentially be used for implementing the alpha-channeling in realistic mirror devices. We also propose a new technique for using the alpha-channeling wave energy to catalyze fusion reaction by employing minority ions as a mediator species.
In the second part of this thesis, the NME manifesting itself as an unusual response of a resonant particle to external adiabatic perturbations mimicking the behavior of a particle with a negative mass, is discussed. Using the Hamiltonian perturbation theory, the calculation of the effective parallel mass is extended to the non-vacuum waves and the NME is shown to be robust. Also, the consequences of radiation friction and collisions with the background particles on the NME are studied and new collective phenomena emerging in plasmas with negative-mass particles are considered.

▼ Atomically precise thiolate protected gold nanoparticles (AuNPs) known as gold nanomolecules (AuNMs) are intensely pursued owing to their feasibility to elucidate their structure by single crystal X-ray crystallography. They have distinct number of Au atoms (n) and thiolate (-SR, R-hydrocarbon chain) ligands (m) with molecular formula of the form [Aun(SR)m]. AuNMs are made of a gold core protected by a thiolate-monolayer and possess size-dependent properties conferred by quantum confinement. Atomic precision has been achieved in the 1-3 nm range and crystal structures of several AuNMs ranging from 18 to 279gold atoms have been studied. They provide significant insights into the structural assembly of AuNMs and surface protection motifs. Also, AuNMs in the range of 1-3 nm are the
most ideal form of AuNPs and they can be
predictably manipulated at the atomic level. Therefore, this dissertation will focus on addressing the factors governing the formation of unique atomic structure, composition, metal-ligand interface and their properties have been addressed in detail. In this dissertation, the thiolate ligands are categorized into three main classes, namely;
aliphatic, aromatic and bulky thiolate ligands. These distinct classes of thiolate ligands exclusively form a unique series of AuNMs and unique size-dependent properties.
Thiolate monolayer protecting the gold core of AuNMs have been shown to greatly influence the atomic structure, surface chemistry, composition and physicochemical properties of AuNMs. Therefore, investigation of ligand
effect on atomic structure of AuNMs would provide insights into designing the atomic structure and surface assembly architecture of AuNMs and atomically precise nanomaterials beyond 3 nm as well. Numerous synthesis, molecular conversions and interconversions, crystal structures and various applications of AuNMs have been reported over the past 5-10 years.
The idea of ligand effect to tune the atomic structure and properties of materials which has not been reviewed comprehensively and critically to date, would be highly beneficial and relevant to this field as well as other fields of metal cluster research. Tailoring chemical structure of metal nanoparticles is of paramount importance to utilize them effectively in related applications. This dissertation comprehensively and critically describes,
a fundamental criterion, namely, the ligand effect on nanoparticles’ atomic structure, metal-ligand interface and properties of thiolate-protected AuNPs, which must be focused to enable nanoengineering at atomic level. Overall, the work presented in this dissertation discuss; 1. The influence of thiolate-ligands on atomic structure and formation of AuNMs, and their physicochemical properties will be established based on experimental and computational studies. 2. The ligand
effect on atomic structure of AuNMs to reveal that ligand engineering is a promising means to enable us to achieve atomically precise next generation nanomaterials and…

▼ Although a multitude of factors affecting hand hygiene (HH) adherence have been investigated in the literature, limited research has specifically explored the moderating/
interaction effects among these factors. A secondary analysis of pooled self-reported HH adherence data, collected for two previous Canadian studies, was conducted to explore the presence of such
interaction effects. Within a combined sample of 465 physician and nursing student participants, 67.1% were deemed adherent, with self-reported performance of HH before and after every patient contact at a minimum of 90% of the time.
Gender was found to moderate the relationship between forgetfulness and HH adherence within the merged dataset. Perceived forgetfulness significantly decreased HH adherence among male respondents only. In addition, perceived busyness was found to moderate the relationship between forgetfulness and HH adherence among nursing students. Forgetfulness decreased HH adherence, but only for those nursing students who did not perceive busyness as a factor impacting their HH adherence.
The study findings highlight the need to explore moderation/
interaction effects to enrich our understanding of factors affecting HH, enabling more effective, targeted interventions to improve adherence.

▼ Scholarship on the impact of visits by the president of the United States on midterm gubernatorial elections is limited. This paper will examine the effects of such visits by the president of the United States on midterm gubernatorial elections. Cohen, Kreassa, and Hamman (1991) analyzed the impact of presidential visits on senate races and discovered these visits are strategic; also, when the president gets involved in an election, the president has a positive impact. I also believe that when different visits are split out different types of visits will have different effects. This is based on the time commitment of the president as the more time spent on a visit the greater the impact the visit should be. Using an original dataset, I evaluate how visits by the president effect vote share; this is as I seek to adapt some of the findings of the strategic calculations of the president to determine the impact of those visits by the president. My analysis shows that presidential visits have a positive effect on the vote share of the midterm gubernatorial candidates. In addition, I find that rally visits have the most consistent positive impact on candidates over the other types of visits analyzed in this study. Finally, when analyzing the interaction between visits and partisanship, the impact of a visit has variation dependent on the partisan composition of a state.

▼ This dissertation investigates three questions: First, what conditions make dissident collective action such as protest, revolt, rebellion, or civil war more likely to happen in a country? Second, what conditions make citizens more likely to join in dissident collective action? Third, does Internet use play a role in dissident collective action, and if so, why? I argue that motives and resources are necessary rather than sufficient conditions for dissident collective action. I develop an analytical framework integrating motives and resources. Specifically, I theorize that state repression is an important motive, and that civil society is critical in providing resources. Four statistical analyses are conducted to test the hypotheses. Using aggregate level data on countries over time, I find that civil war is more likely to occur in countries where both state repression and civil society are strong. Moreover, the
effect of civil society on civil war onset increases as the repression level rises. at the individual level using 2008 Latin American Public Opinion Project surveys from 23 Latin American and Caribbean countries, I find individuals more likely to join in protest when they experience both more repression and greater civic engagement. Moreover, civic engagement’s
effect on protest participation increases as people experience more repression. I further find that Internet use constitutes a kind of civic engagement and has effects similar to voluntary group involvement. the
effect of Internet use on protest participation decreases as a person’s civic engagement increases. Finally, an individual is more likely to join in protest when experiencing more repression and using the Internet more frequently. Moreover, the
effect of Internet use on protest participation increases as a person experiences more repression.
