In this dissertation recent advances in modeling various atomic and molecular systems with quantum mechanical calculations employing explicitly correlated Gaussian functions are presented. The author has utilized multiple approaches and considered a number of approximations to develop optimal calculation frameworks. Electronic and muonic molecules and atoms have been considered. A number of unique calculations have been performed and some novel and interesting results, including high accuracy description of the charge asymmetry in the heteronuclear systems and lifetimes of rotationless vibrational levels of diatomic molecules, have been generated.

The following dissertation investigates a problem related to the practice of quantum tomography, where one usually estimates the parameters associated with quantum states or measurements. In particular, the question answered is whether and how one could detect if states and measurements are correlated. A similar question answered is how one could detect state-preparation non-localities and measurement non-localities in multiqudit systems. The solution involves an analysis of certain matrix quantities called \emph{partial determinants}. Partial determinants are an application of the Born rule that can be interpreted as tomography over a loop in the space of state and measurement settings. From this perspective, the notion of state and observable become \emph{non-holonomic} | that is, state and observable parameters can be defined ``locally'' over each setting but not globally over all settings. As such, state and measurement parameters are not estimated because such estimated values don't exist in correlated systems, but rather the inability to estimate such values is quantified. Therefore, partial determinants are a measure of the amount of contradiction that would result from any claim of such a estimated values by propagating these estimates through a `tomography loop' of data collected by various experiments. Such measures of contradiction are generally known as \emph{holonomies}.

Thin target L-Shell x-ray production cross sections for protons incident on ₆₂Sm and ₇₀Yb in the energy range of 0.3 to 2.4 MeV/amu, alpha particles incident on ₆₂Sm, ₇₀Yb, and ₈₂Pb in the energy range of 0.15 to 4.8 MeV/amu, and lithium ions incident on ₅₈Ce, ₆₀Nd, ₆₂Sm, ₆₆Dy, ₆₇Ho, ₇₀Yb, and ₈₂Pb in the energy range of 0.8 to 4.4 MeV/amu have been measured. The cross section data have been compared to the planewave Born approximation (PWBA) and the PWBA modified to include binding energy and Coulomb deflection effects. The Lα₁,₂ x-ray production cross sections are best represented by the PWBA modified to include both the binding energy and Coulomb deflection effects (PWBA-BC) over the entire incident ion, incident energy, and target ranges studied. However, the Lγ₁ and Lγ₂,₃,₍₆₎ x-ray production cross sections are best represented by the PWBA except at the lower ion energies, where both the PWBA and PWBA-BC are in disagreement with the data. The comparison of Lα₁,₂/Lγ₂,₃,₍₆₎ ratios to theory reveals that the PWBA-BC does not predict the inflection point substantiated by the data, and the agreement between the data and the PWBA-BC becomes worse as the atomic number of the incident ion increases. Comparison of the PWBA modified to include binding energy effects CPWBA-B) and the PWBA modified to include Coulomb deflection effects (PWBA-C) to the Lα₁,₂, Lγ₁, and the Lγ₂,₃ cross sections for protons, alpha particles, and lithium ions incident on ₇₀Yb indicates that the PWBA-C overestimates the magnitude of the data but does describe the shape of the L₁-associated cross section while the PWBA-B underestimates the magnitude of the data but fails to predict the proper shape of the L₁-associated data. In order to evaluate the ability of the PWBA and the presently accepted modifications to the PWBA to fit the experimental data, future experimentation should be conducted in the energy range that includes the point where the ratio of the incident ion velocity to the L-Shell electron velocity is equal to 0.19 (i.e., V₁/Vₗ = 0.19). This is where the L₁-associated cross sections begin to exhibit the shouldered structure and the cross section ratios L₃/L₁ and L₂/L₁ have inflection points.

Syftet med studien är att skapa en djupare insikt om Born Globals-företags kunskapsanskaffning inför en snabb internationalisering. Studien avser även att undersöka hur internationaliseringen skiljer sig från tidigare modeller. För att nå syftet med studien har en huvudfråga formulerats med utredande delfrågor, huvudfrågan lyder; hur införskaffar Born Globals-företag kunskap inför deras internationaliseringsprocess? För att kunna besvara vår forskningsfråga och uppfylla syftet med undersökningen har vi använt oss av en kvalitativ forskningsmetod. Vi har intervjuat tre nyckelpersoner i tre Born Globals-företag om anskaffningen av kunskap inför internationaliseringen. Resultatet som framkommit av intervjuerna visar att de olika kunskapskällorna samt kunskapsinnehållet har varit av varierande betydelse för företagens internationella expansion, där den direkta erfarenheten huvudsakligen erhållen av grundarna uppmärksammas. Även grundarnas nätverk och färdigheter visar sig vara betydande inför internationaliseringen. Vidare visar även resultatet att internationaliseringsprocessen i Born Globals är mer individfokuserad, det är grundarnas och andra individers erfarenheter, färdigheter, kunnande och nätverk som ligger till grund för internationaliseringen. Medan processen i Uppsalamodellen är mer organisatoriskt förankrad och tidskrävande.

Over 18 million caesarean sections (CS) are performed around the world each year, with many being planned repeat CS which may lack absolute indications. Abdominal delivery on this scale demands an appreciation of the lasting impact, positive or negative, on the health of women and children. Maternal outcomes of planned CS birth have been extensively investigated, but knowledge of outcomes for offspring is largely limited to those occurring in the neonatal period. Avoiding labour and vaginal birth may protect offspring from birth injuries, but could also adversely affect their later health due to avoidance of physiological processes which aid immunity and gut function. Concern that CS may compromise offspring health has arisen from studies which demonstrate an increased risk of chronic health problems following CS compared with vaginal birth. However, the clinical implications of existing studies are unclear due to high risk of selection bias, confounding and lack of power. Studies which can overcome these issues are required. Studies focusing on offspring of women with a history of CS mean the risk of confounding by indication for CS is minimised, as the majority of repeat CS are planned due to maternal preference rather than medical indications. At present, it is not known whether perceived offspring health outcomes of mode of delivery drive women's birth choices after a previous CS, and if so, whether such beliefs reflect evidence-based information on offspring risks. The existing literature highlights a number of factors that may play a role in shaping these birth choices, but no studies have attempted to identify beliefs which independently predict birth preferences after a CS. Such a study has potential to identify key beliefs to target in future interventions designed to optimise women's birth choices. This project investigated both the health of offspring delivered by planned repeat CS and women's beliefs which predict their preferred mode of delivery after CS. Offspring health was investigated using a population-based cohort study. Pregnant women's beliefs about birth after CS were investigated using a synthesis of qualitative literature and a theory based interview and questionnaire study.

M.A. (Clinical Social Work) / This research involves exploring how middle childhood boys at a primary school experience the phenomenon of growing up with an absent father both functionally and psychosocially. The absent father being defined as a living father who does not live with his son and has chosen to be uninvolved in a financial, physical, emotional or spiritual way and has little contact with his son. The goal of the study was to investigate the effect of absent fathers on middle childhood boys and to gain an understanding of how they view the absence of a father in their lives. The objectives included exploring the experience of the boys in growing up with an absent father, to determine the boy’s perception of how their father’s absence has impacted on their lives, as well as to make recommendations for social work and other social service practitioners. A qualitative approach was selected for this study with a view to allowing participants to give rich descriptions of their individual experiences of growing up with an absent father. It is an exploratory study, informed by phenomenology. Exploratory, as it necessitated gaining insight into a situation and phenomenological as it entailed describing the participants experience of their life story. The research population for this study was defined as all boys in Grade Seven at the primary school. The boys were aged between twelve and thirteen. Purposive sampling was used as it allowed the researcher to select the participants based on necessary and relevant criteria. Five participants were selected as the researcher believed that it would give a sufficient overview of the phenomenon being researched and would reach data saturation. The interviews were all started with the same request namely, “Tell me about your relationship with your father?” Thereafter a semi-structured interview schedule was used as a backup tool when relevant questions needed to be asked. Participants were prepared for the interviews prior to the commencement of the study. Data was analysed according to a phenomenological method namely, Familiarisation; Immersion/Bracketing; Inducing Themes; Coding; Elaboration and Interpretation. These procedures were followed until a full description of the participants’ experience of absent fathers was disclosed. Four themes namely, emotions, loss, self-esteem and the single mother were identified ...

Cette thèse aborde la thématique de l’internationalisation des petites et moyennes entreprises (PME) globalisées dès leur naissance ou peu de temps après, et nommées dans la littérature anglosaxonne « Born Globals ». Plus spécifiquement, notre recherche est focalisée sur l’approche décrivant les relations des « Born Globals » avec le réseau d'influence développé sur le territoire d’implantation des entreprises. Au delà des formes multiples de réseaux accompagnant les entreprises dans leur démarche d’internationalisation (relationnels, informels, personnels et territoriaux), nous pensons que le réseau d'influence joue un rôle dans l’internationalisation de ces PME. « Quel est le rôle du réseau d’influence dans l’internationalisation des « Born Globals » ?» Pour répondre à cette question, nous avons réalisé une étude auprès des « Born Globals » implantées dans la région de Kalouga en Russie.Les résultats de notre recherche nous permettent de définir les principales caractéristiques du réseau d’influence (les acteurs, les liens entre eux et les ressources qu’ils partagent avec les entreprises) dans l'internationalisation des « Born Globals », de cartographier ce réseau afin d'apprécier le rôle de chacun et de définir les étapes de l'intégration des « Born Globals » par le prisme de ce réseau sur un territoire donné. Ces éléments peuvent être exploités aussi bien par les théoriciens du point de vue des différentes étapes mises en évidence, que par les dirigeants des « Born Globals » lors de leur internationalisation dans d'autres pays et enfin par les pouvoirs publics qui cherchent à attirer des investisseurs étrangers et améliorer leurs prestations. / The main topic of this thesis is the small and medium entreprises (SMEs) that go international from their inception or shortly after. These business organizations were named in the Anglo-Saxon literature "Born Globals". More specifically, our research is focused on the approach describing the relationships of the "Born Globals" with the influence network developed in the area of their currrent location. Beyond the multiple forms of networks supporting companies in their internationalization process (relational, informal, personal and territorial), we think that the influence network plays the most important role in the internationalization of SMEs. "What is the role of the influence network in the internationalization of "Born Globals"?" To answer this question, we conducted a survey about "Born Globals" located in the Kaluga region in Russia.The results of our research allow us to describe the main characteristics of the influence network (players, links between themselves and the resources they share with companies) in the internationalization of "Born Globals" and to elaborate the network map and to define the different integration phases of "Born Globals" in the local network. Our results can be used by academic researchers, managers and leaders of "Born Globals" in their internationalization process and finally by the government seeking to attract foreign investments and improve their performances.

Prestack depth migration requires an accurate kinematic velocity model to image the subsurface correctly. Wave equation migration velocity analysis techniques aim to update the background velocity model by minimizing image residuals to achieve the correct model. The most commonly used technique is differential semblance optimization (DSO), which depends on applying an image extension and penalizing the energy in the non-physical extension. However, studies show that the conventional DSO gradient is contaminated with artifact noise and unwanted oscillations which might lead to local minima. To deal with this issue and improve the stability of DSO, recent studies proposed to use an inversion formula rather than migration to obtain the image. Migration is defined as the adjoint of Born modeling. Since the inversion is complicated and expensive, a pseudo inverse is used instead. A pseudo inverse formula has been developed recently for the horizontal space shift extended Born. This formula preserves the true amplitude and reduces the artifact noise even when an incorrect velocity is used. Although the theory for such an inverse is well developed, it has only been derived and tested on laterally homogeneous models. This is because the formula contains a derivative of the image with respect to a vertical extension evaluated at zero offset. Implementing the vertical extension is computationally expensive, which means this derivative needs to be computed without applying the additional extension. For laterally invariant models, the inverse is simplified and this derivative is eliminated. I implement the full asymptotic inverse to the extended Born to account for laterally heterogeneity. I compute the derivative of the image with respect to a vertical extension without performing any additional shift. This is accomplished by applying the derivative to the imaging condition and utilizing the chain rule. The fact that this derivative is evaluated at zero offset vertical extension, makes it possible to compute the derivative without applying the extension. I also verify the newly proposed inversion formula on a laterally variant velocity model. In addition, I test the effect of the computed derivative and compare its contribution with the full formula. This additional term has overall limited influence on conventional images. Its largest impact is on vertical reflectors such as salt flanks, granted the velocity is varying laterally in the background as often is in this case. Otherwise, for most applications, we can obtain good quality extended images without this additional term.
