Mild steel, armour steel (Armox 370T and 440T), Aluminium alloy 5083-H116, Twintex and Dyneema square plates were blast loaded on a horizontal pendulum at the Blast Impact and Survivability Research Unit (BISRU), University of Cape Town. The blasts were generated by detonating disc-shaped PE4 explosives of various diameters and standoff distances. The chosen plates are of side length 500mm (4mm thick mild steel and armour steel plates) and side length of 400mm (aluminium, Twintex and Dyneema panels). The charge mass was varied between 9g and 60g for two charge diameters, namely: 50mm and 75mm, and stand-off distances of 25mm, 38mm and 50mm. A polystyrene bridge was used to position the charges at the centre of plates, without any polystyrene between the charge and the plate in order to minimise any effects the polystyrene may have had on the plate deformation. The transient response of the 500mm square plates (mild steel and Armox 370T) was measured with the use of Light Interference Equipment (LIE) and numerical simulations performed in ANSYS AUTODYN, with the aim of gaining greater insight into the response of the two different materials. The details of the experimental setup and method used for the LIE as well as the development of the AUTODYN computational model are presented. The air and explosive were modelled as Arbitrary Langrange-Euler (ALE) elements while the test plates were modelled as Langrangian shell elements. Since the geometry of the plates was square, the simulations had to be performed in 3D quarter-symmetry. The transient response, permanent final displacement and maximum transient displacement of the numerical simulations were compared to the corresponding experimental results. The mild steel plates all exhibited good correlation between experimental and simulated results. However, the Armox 370T simulated results showed an under-prediction of the displacement magnitude and impulse compared to the experimental results. Experimentally, both the mild steel and armour steel exhibited a linear increase in deformation with increasing charge mass. Blast tests were also performed on 3mm thick mild steel, aluminium, Twintex and Dyneema square plates of 400mm side length. The aim was to gain a greater understanding and compare of the response of different material types (ferrous, non-ferrous, Glass Fibre Polypropylene and Ultra High Molecular Weight Polyethylene) under blast loading. The aluminium plates performed better than the mild steel, on an equivalent mass basis, in terms of permanent displacements and failure threshold impulse. The aluminium plates were significantly thicker (10.5mm compared to 3mm) than the mild steel plates, which may have contributed to its response under blast. The Twintex panels mostly exhibited failure in the form of fibre fracture and matrix failure whereas the Dyneema panels only exhibit large inelastic deformation, although the Dyneema were clamped differently to the other panels. Dimensionless analysis was performed on all of the materials except for Dyneema. Initially a scaling factor was used to account for the varying stand-off distances but proved to be unnecessary due to the type of confinement used (unconfined free air-blasts versus partially confined tube). Once the scaling factor was removed, the dimensionless impulse values showed relatively good linear correlation with the predicted trend.

Transportation planners, engineers, and administrators face the difficult tasks of prioritizing and justifying proposed investments in transportation infrastructure, particularly as government budgets tighten and alternative investments compete for public funding. One means by which professionals can prioritize and justify large transportation investments is by describing how a proposed project will impact an area’s economy in terms of creating new jobs, raising aggregate income, and increasing business revenues. The report begins by examining the general impact of transportation investments on economic development. Then it surveys various methods and tools that have been proposed for estimating economic impacts. Among these, the TREDIS economic impact model is selected and used to estimate the economic impacts of a current interstate highway project in Texas. / text

Lorsque nous parlons de relations internationales, nous parlons généralement de diplomatie et d'investissement, Le sport peut être utilisé comme outil pour améliorer la diplomatie entre les pays, ainsi que pour développer les intérêts économiques et sociaux. De plus, le sport occupe une place importante dans le repositionnement de l'image d'une nation, tout en améliorant le processus d'intégration des jeunes générations dans le monde. L'un des principaux intérêts, du point de vue du gouvernement, est de créer un lien affectif positif avec la nation hôte de l’évènement sportif. Ce qu'on appelle le soft power. Le but de ce travail est d'explorer certaines des façons dont le sport est utilisé pour générer ce pouvoir, et comment il peut contribuer à générer du contrôle ou à provoquer de l'influence, en se concentrant sur l'État du Qatar. Ce travail est séparé en trois parties principales. Je présente d'abord le développement du sport et la manière dont les événements sportifs ont été utilisés par différents pays et régimes politiques, ainsi que l'impact généré. Deuxièmement, j'essaie de comprendre l'impact généré par l'investissement du Qatar dans l'équipe de football française du Paris Saint-Germain. Et troisièmement, en mesurant l'impact socio-psychologique généré par la jeune génération en organisant des événements sportifs internationaux, le cas du championnat du monde de handball 2015. Ce travail vise à clarifier comment un tel investissement est perçu comme une opportunité de développement au sein de la société, et d'améliorer la diplomatie. En se concentrant sur l'évolution dont le sport est utilisé comme un outil important dans le processus de socialisation des jeunes dans la société mondiale. Sur la base de mes recherches, le résultat de l'investissement dans le Paris Saint-Germain était une situation «gagnant-gagnant» entre la France et le Qatar sur le plan social, économique et politique. De plus, l'utilisation des événements sportifs a eu un impact émotionnel positif, faisant admirer aux résidents la vision du gouvernement. La jeune génération, quelle que soit sa nationalité, a une vision positive des efforts du gouvernement pour s'améliorer et se développer. La vision du gouvernement du Qatar était saillante pour la jeune génération au Qatar. / When we mention international relations, we generally talk about diplomacy and investment, but there are other ways of promoting the interests of a government on the international stage. Sport can be used as tool to improve diplomacy between countries, as well as developing economic and social interests. Additionally, sport takes an important place in shaping the image of a nation, while it improves the integration process of young generations into the world. One of the main interests, from a government perspective, in the use of sport, is to generate a positive emotional connection to a host nation - what is known as soft power. The aim of this work is to explore some of the ways in which sport is used to generate this power, and how it can provide a type of control or influence. Specifically, it will focus on the State of Qatar. This work is separated to three main parts. First I present the development of sport and the way sport events were used by different countries and political regimes, and the impact generated. Second, I try to understand the impact generated from Qatar investment in the French football team Paris Saint-Germain. And third, I measured the socio-psychological impact generated on the young generation from hosting international sport events, as in the case of the Handball World championship 2015.This work sets to clarify how allowing such investment is perceived as an opportunity for development within the society, and to improve diplomacy. Additionally, focussing on the young generation allows me to study the evolution of how sport is an important tool in the process of socialization of young people into global society. Based on my research, I argue that the result of the Paris Saint-Germain investment was a "win-win" situation between France and Qatar on the social, economic, and political level. Also, using sport events generated positive emotional impact, making the residents admire the vision of the government. The young generation, regardless nationality has a positive view of government efforts to improve and develop itself - the Qatari government's vision was salient to the young generation in Qatar.

The purpose of this study was to assess the relationships between family/home satisfaction and job satisfaction of single working mothers with at least one child under the age of 18 living at home. The principal objectives were to identify the stressful situations in the lives of working single mothers and the factors that contributed to home satisfaction and work satisfaction. Data were gathered by survey questionnaire from single working mothers presently living in Iron County, Utah. Factor analysis was used to reduce data into home satisfaction and work satisfaction factors that were analyzed by multiple regression to determine the variance they explain. Stepwise multiple regression identified 1) family interaction, 2) income, housing, and health, and 3) family diet and money management as the home and family factors that predict satisfaction with home life. This multiple regression identified 1) family interaction, 2) time commitments, 3) income, housing, and health, 4) family and community support, and 5) family diet and money management as the home and family factors that can predict satisfaction with work. The work factors that can predict home life satisfaction were found to be 1) work schedule, 2) work environment, and 3 ) salary and advancement. Work factors that predict satisfaction with work were 1) breaks and control, 2) schedule and salary, and 3) commuting and friends at work. Working single mothers identified single parenting, financial problems, major changes in work or family, and problems with children as the situations causing stress in their lives. A statistically significant relationship was found with income and 1) education, 2) perception of enough income, 3) satisfaction with home life, and 4) work satisfaction.
