Les cratères d'impact hypervéloces sont les structures morphologiques les plus abondantes à la surface des corps planétaires telluriques du système solaire, sauf sur Terre où ils sont effacés par les processus de surface. La structure interne des cratères d'impact de type complexe ne peut être étudiée en détail que sur Terre par des études géophysiques et géologiques de terrain. De telles approches - combinées à de la modélisation - peuvent révéler comment le processus de cratérisation, la composition des roches cibles, l'érosion et d'autres processus post-impact peuvent conduire aux anomalies géophysiques observées, qui peuvent également être détectées par des données satellitaires sur d’autres planètes. La cartographie du champ magnétique, les mesures gravimétriques, les sondages électromagnétiques (EM34), les analyses paléomagnétiques, le magnétisme des roches et les techniques pétrographiques sont utilisées. Pour la première fois, nous révélons que la structure de Tunnunik récemment découverte présente des anomalies de gravité négative et de champ magnétique positif typiques, ce qui nous aide à reconsidérer l'étendue de la fracturation dans les roches cibles. La structure d’Haughton, moins érodée que Tunnunik, montre des signes d'une aimantation augmentée au centre de son soulèvement central, ce qui est causé par l’altération hydrothermale induite par l’impact. Le paléomagnétisme aide à contraindre les âges différents des deux impacts des lacs à l’eau claire au Québec. Ce travail a des implications importantes pour notre compréhension du processus de cratérisation dans le système solaire, notamment en ce qui concerne l'étude des surfaces planétaires. / Hypervelocity impact craters are the most abundant morphologic features on rocky planetary bodies of the solar system, except on Earth where they are erased by surface processes. The internal structure of complex impact craters can only be studied on Earth by using ground-truth geophysical and geological studies. Such approaches - combined with modeling - can reveal how impact cratering, target geological composition, erosion and other post-impact processes can lead to the observed geophysical anomalies, which could also be detected by remote geophysical data on other planetary surfaces. Magnetic field mapping, gravimetry measurements, electromagnetic soundings (EM34), paleomagnetic analyses, rock magnetism and petrography techniques are used. For the first time, we reveal that the recently-discovered Tunnunik impact structure has typical negative gravity and positive magnetic field anomalies, which help us to reconsider the brecciation extent in the target rocks. The Haughton crater, which is less eroded than Tunnunik, shows evidence for an enhanced-magnetization in the core of the central uplift, caused by impact-generated hydrothermal alteration. Paleomagnetism helps to constrain the different ages of the East and west clearwater lake impacts. This work has important implications for our understanding of impact-cratering in the solar system, especially concerning the study of planetary surfaces.

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Timothy D. Keane / Visual Resource Management practices are relatively new, dating back to the late 1960’s and early 1970’s (Litton, 1984; USDA Forest Service, 2010). At the conception of visual resource management practices, computers were not prominent in everyday life. As computing tools advanced along with easier access to technology, a perceived surge of research emerged within the VRM field in the 1990’s. Since that time, it appears that few landscape architects have continued to research how modern technological advancements, specifically the recent expansion of virtual reality, could be used in predicting the visual impacts of proposed development. This report aims to compare virtual environments to existing methods for assessing the visual impacts of development in the Texas prairie ecoregion. New reliable tools at the hands of experts could lead to more accurate and more understood consequences of development on the visual landscape. Following precedents set forth in similar research studies, participants will view photographic and rendered images of scenes before and after development projected through a digital display. Potential development will be analyzed through a comparison analysis in which multiple visualization methods (Google Earth and photo sphere images) are compared to industry standards of two-dimensional images and renderings. The comparison analysis will survey experts and ask them to rate certain views before and after development through multiple visualization methods. Results from the study show a high similarity in perceived impacts between 2D images and Google Earth assessments. However, photo sphere images were rated consistently lower than their counterparts. Image resolution and detail could have led to the lower ratings in photo sphere images. Overall, participants felt that immersive visualization media will soon replace the use of 2D images for conducting visual impact assessments.

Class of 2014 Abstract / Specific Aims: The purpose of this quality improvement project was to compare the completeness of home medication lists generated upon hospital admission between pharmacy student interns and nurses. Methods: This project was a retrospective review of completed home medication lists obtained by pharmacy student interns or nurses in a Southern Arizona community hospital. During August and September 2013, medication lists from the previous day’s admissions were collected and de-identified. Medication lists were included in the evaluation if the patient was admitted directly to the hospital or through the emergency department, stayed for at least 24 hours and had at least one home medication upon admission. The primary outcome was the number of omissions left on home medication lists completed by pharmacy student interns or nurses. An omission was defined as any missing information in the medication list categories of drug name, dose, unit, route or frequency. Main Results: Fifty medication lists that included 519 medications were collected in the pharmacy student intern group and forty-four lists that included 376 medications were collected in the nurse group. Of the total medications, nurses left significantly more omissions in the categories of dose (19% vs. 1.9%), units (20.2% vs. 2.3%), and frequency (11% vs. 0.7%), where the P-value was < 0.05 for each. Lastly, the total number of omissions left by nurses compared to pharmacy student interns was significantly different (201 vs. 35 omissions, P < 0.05). Conclusion: Compared to nurses, these results suggest pharmacy student interns left fewer omissions and created a more complete home medication list for patients being admitted to the hospital.

M.Phil. / The urban environment, as a concentration of human industrial activity, has an ecological footprint extending well beyond its geographic borders. The reactive nature of Environmental Impact Assessment methodologies focuses on impacts in the natural environment, and mitigation thereof, rather than the causes, and since cities incorporate only limited natural resources, their impact on the larger environment is easily overlooked within the urban setting. Urban design and planning aims to guide urban development, and in order for such development to occur sustainably in the natural, built, social and economic environments, a strategic approach to environmental assessment must be followed. This study explores the merits of a strategic environmental assessment as a pro-active methodology to guide urban master-plan development at precinct level towards more sustainable urban layout and form. The Civic Precinct of the newly formed Ekurhuleni Metropolitan Municipality, to be established within the heart of Germiston, South Africa, serves as a case study. Having contextualized strategic assessments in an urban environment on the basis of a literature review, the study defines the development vision on the basis of higher-tier strategic documents and planning frameworks formulated for Ekurhuleni. Screening explores the legal parameters, and serves to define a vision specifically for sustainability of the Civic Precinct. Scoping has been conducted with reference to existing research data available from highertier studies and GIS databases, and at precinct-specific level fieldwork has provided both qualitative and quantitative status quo data, which have been transferred onto maps to highlight resources and constraints. At an applied level this study has yielded direct outcomes: i) A matrix of criteria for sustainability in the urban environment has been generated from the United Nations Agenda 21, and the Plan of Implementation from the World Summit on Sustainable Development (Johannesburg, 2002), supplemented by assessment criteria of the Leadership in Energy and Environmental Design for Neighbourhood Development Rating System. The matrix forms a generic checklist for planners and designers, applicable also in other urban renewal projects. ii) The review of higher-tier planning documentation for Ekurhuleni, supplemented by fieldwork, has provided a comprehensive set of qualitative and quantitative data relating to the environment of the Ekurhuleni Civic Precinct. iii) By relating the results of the fieldwork, through a SWOT analysis, to the predetermined criteria for sustainability, a project-specific set of sustainability guidelines has been formulated. These guidelines are direct design informants for the master-plan, and become specifications for sustainability of individual projects to be implemented in the context of the master-plan. Through these outcomes the case study demonstrates that an adapted strategic environmental assessment methodology offers an effective tool for pro-active focus on sustainability in lower-tier, pre-implementation urban planning and design processes. The study, however, also indicates that the geographic confines of an urban precinct may be too restrictive to do justice to all dimensions of sustainability which make up an urban system, and suggests that application of the SEA methodology should be explored at the broader level of the local spatial development plan, where the SEA methodology may be more economically applied. The local spatial development plan offers a more appropriate level at which to conduct strategic environmental assessment, since it offers a broader scope for strategic consideration of the interconnectedness of all spheres of sustainability, while still permitting sufficient detail in the outcomes to make a concrete difference to the sustainability of an urban design when implemented.
