The biochemical composition of conifer foliage in the Greater Victoria Watershed District (GVWD), Vancouver Island, Canada, was examined using hyperspectral remote sensing data. Imagery acquired from the airborne sensor Advanced Visible/Infrared Imaging Spectrometer (AVIRIS) was compared to sampled foliar chemical measurements to provide regional maps of biochemical distribution. The biochemical concentrations of nitrogen, chlorophyll and moisture derived from AVIRIS data were analyzed to provide an analysis of the forest canopy, comprised predominantly of Douglas-fir. The AVIRIS data were preprocessed to correct for atmospheric and geometric distortion, degradation, and noise inherent in the data in order to properly represent the forest canopy at the time of image acquisition. The AVIRIS data were used to investigate the relationship between the reflectance, absorbance and derivative values present in the imagery corresponding to the sampled chemical data. A total of 29 plots were used in a partial least squares regression analysis to analyze the relationship between the data sets to extract chemical constituents in the forest canopy. Nitrogen and total chlorophyll models have r2 values of 0.73 and 0.68 respectively. Due to the complexity of moisture interaction with hyperspectral data, regression models were unable to be computed for the AVIRIS data over the GVWD. Regression models were then applied to the entire AVIRIS dataset for regional mapping of the canopy biochemistry. The distribution of nitrogen and total chlorophyll in the forested areas of the GVWD was mapped.

This thesis situates women as stakeholders in Canada’s post-war suburban development in their roles as designers, builders, owners and investors. By 1949, 60 percent of properties in the Municipality of Oak Bay, a suburb of Victoria, British Columbia, were held in female ownership. Most women owned houses jointly with their husbands. Others owned houses, vacant lots, commercial buildings and investment properties solely in their name. To understand the role that women played in shaping the built landscape of this post-war Canadian suburb between 1940 and 1960, information for each female owned property, along with a 20 percent sample, was collected from the municipality’s 1949 property assessment roll. Results were matched with a Geographic Information System (GIS) to illustrate the spatial characteristics of these ownership patterns and building permit records were examined. In-depth interviews were conducted with eleven women who spoke about their own or a relative’s experiences as property owners.

While it is generally agreed that family homelessness is rapidly increasing, there is very little research to find out how families have exited homelessness and become stable. There is even less research to investigate the strengths that were employed by family members as they journey toward housing stability. Is it possible that this potentially dis-empowering experience can be enriched by the care and support of fellow community members and helping professionals? More importantly, can family members draw on this experience to recognize their inner strengths and move toward greater happiness and self-sufficiency? This thesis shows how families who have been displaced from their community due to an experience of homelessness can be better supported to return to a stable life. A narrative lens was used to investigate the findings from semi-structured, one-on-one interviews with three mothers. One of the main criteria was that they found and retained stable housing for at least one year. The families in question currently live in Victoria, B.C. Canada, where this research took place. Examination of participant’s narratives revealed a five-stage process in which inner strengths and outer community supports combined to assist them in moving toward their goals. Participant mothers were able to access new ways to view the situation that did not leave them feeling marginalized. They also built both material and social assets that led to greater happiness and stability. Participants were able to develop resilient behavior by drawing upon past experience for knowledge, insight and inspiration. They overcame inner and outer barriers to these strengths by communicating their needs and reaching out to family, friends or services in a more confident way.

This thesis develops and explores two methodologies to assess earthquake ground shaking in southwestern British Columbia based on 1D soil layering and 3D basin structure. To assess site response based on soil layering, microtremor array measurements were conducted at two sites of contrasting geology to estimate Rayleigh-wave dispersion curves. A Bayesian inversion algorithm is developed to invert the dispersion data for the shear-wave velocity (VS) profile together with quantitative uncertainty estimates, accounting rigorously for data error covariance and model parameterization selection. The recovered VS profiles are assessed for reliability by comparison with invasive VS measurements at each site with excellent agreement. Probabilistic site response analysis is conducted based on a sample of VS profiles drawn from the posterior probability density of the microtremor inversion. The quantitative uncertainty analysis shows that the rapid and inexpensive microtremor array method provides sufficient resolution of soil layering for practical characterization of earthquake ground motion. To assess the effects of 3D Georgia basin structure on long-period (> 2 s) ground motion for large scenario earthquakes, numerical 3D finite difference modelling of viscoelastic wave propagation is applied. Both deep (> 40 km) subducting Juan de Fuca plate and crustal (5 km) North America plate earthquakes are simulated in locations congruent with known seismicity. Simulations are calibrated by comparing synthetic waveforms with 36 selected strong- and weak-motion seismograms of the 2001 MW 6.8 Nisqually earthquake. The ratio between predicted peak ground motions in models with and without Georgia basin sediments is applied as a quantitative measure of basin amplification. Steep edges in the upper 1 km of the northwest and southeast extents of the basin are coincident with the appearance of surface waves. Focussing of north-to-northeast propagating surface waves by shallow (< 1 km) basin structure increases ground motion in a localized region of southern Greater Vancouver. This effect occurs for both types of earthquakes located south-southwest of Vancouver at distances greater than ~80 km. The predicted shaking level is increased up to 17 times and the duration of moderate shaking (> 3.4 cm/s) is up to 16 times longer due to the 3D Georgia basin structure. / Graduate

This study investigates middle school students’ interest in learning about the Holocaust, which methods are the most effective at teaching the Holocaust and how the testimony of Holocaust survivors can be retold to the next generations of middle school students. In order to answer these research questions, my study uses surveys with three classes of current middle school students in Greater Victoria, British Columbia, a focus group with graduate students at the University of Victoria and an interview with Larissa Weber, the director of the Anne Frank Exhibition in Berlin. These quantitative and qualitative results are analyzed using a mixed methods approach. The middle school students’ perceptions regarding effective educational methods when teaching the Holocaust in my limited sample (n=77 in the first survey and n=58 in the second survey) suggest that there is a connection between personal narrative and empathy when teaching the Holocaust in middle school classrooms. These findings are contextualized with a summary of the history of Holocaust education in Canadian public schools and a discussion regarding the role of empathy in learning about the Holocaust. / Graduate / 0515 / 0311 / 0534 / natashaw@uvic.ca

This thesis presents the distribution of strong wind and wind pressure in the Greater Victoria area associated with winter mid-latitude cyclones based on climate data from the School-Based Weather Station Network during 6 selected days in the winters of 2006, 2007 and 2008. The objectives of this study are i) to test whether synoptic conditions favourable to severe mid-latitude cyclonic storms that are well described in the literature were associated with the selected storms, ii) to determine the time patterns of high wind speed and its direction and maximum gusts, iii) to test necessity of considering the spatial variation in air density and its controls in general assessments of the spatial variation in wind pressure and wind damage potential in the local area, iv) to identify potential areas susceptible to wind damage. Observations taken every second were from Davis Vantage Pro2 TM Plus weather stations located on the southern edge of school building roofs. Thirty-minute means and gust wind speeds were used. All six storms went north of Victoria. The synoptic conditions associated with the selected mid-latitude cyclones agreed with the ones described in literature. Strongest winds at most stations were generally from the southwest, and multiple wind speed peaks were found. The daily iii  maximum gust wind speeds were found before and/or after the highest mean wind speed peak. The spatial variation in air density and its controls were found to be negligible. Although there are a number of interacting causes of the distribution, strongest winds were at stations with smooth surrounding surfaces, close to the southern shoreline, on exposed slopes and/or near relief constrictions. The area with greatest wind speeds and damage potential was found from the east of downtown extending to Lansdowne Middle School. This study provides new knowledge of winds in the Greater Victoria area and contributes to people’s better response to wind storms, land use planning and forecasting severe windstorms. / Graduate / 0368 / mmatsuda@uvic.ca

Between 1870 and 1901, seventeen officers from the British army were appointed by the governments of the Australian colonies and New Zealand as commanders of their colonial military forces. There has been considerable speculation about the roles of these officers as imperial agents, developing colonial forces as a wartime reserve to imperial forces, but little in depth research. This thesis examines the role of the imperial commandants with an embryonic system of imperial defence and their contribution to the development of the colonial military forces. It is therefore a topic in British imperial history as much as Australian and New Zealand military history. British officers were appointed by colonial governments to overcome a shortfall in professional military expertise but increasingly came to be viewed by successive British administrations as a means of fulfilling an imperial defence agenda. The commandants as ???men-on-the-spot???, however, viewed themselves as independent reformers and got offside with both the imperial and colonial governments. This fact reveals that the commandants occupied a difficult position between the aspirations of London and the reality of the colonies. They certainly brought an imperial perspective to their commands and looked forward to the colonies playing a role on the imperial stage but generally did so in terms of a personal agenda rather than one set by London. This assessment is best demonstrated in the commandants??? independent stance at the outset of the South African War. The practice of appointing British commandants in Australasia was fraught with problems because of an inherent conflict in the goals of the commandants and their colonial governments. It resembles the Canadian experience of the British officers which reveals that the system of imperials military appointments as a whole was flawed. The problem remained that until a sufficient number of colonial officers had the prerequisite professional expertise for high command there was no alternative. The commandants were therefore the beginning rather than the end of a traditional reliance upon British military expertise. The lasting legacy of the commandants for the military forces of Australia and New Zealand was the development of colonial officers, transference of British military traditions, and the encouragement of a colonial military identity premised on the expectation of future participation in defence of the empire. The study provides a major revision to the existing historiography of imperial officers in the colonies, one which concludes that far from being ???imperial agents??? they were largely marching to their own drum.

This thesis has investigated the improvement of forecasting temperature in a coastal embayment through the assimilation of sea surface temperature (SST) observations. The research was prompted by the increasing pressures on the coastal marine environment. To better manage the environment, an improved understanding of its future state is necessary. Improving the forecasting of temperature advances our knowledge in this direction. Whilst assimilation of SST is routinely carried out for oceans, its use has been minimal in coastal regions, which is more complicated because of anisotropic covariances and a breakdown of geostrophy in the coastal region. Improvements in computing power, and the introduction of ensemble-based assimilation techniques have made the approach followed in this thesis possible. (For complete abstract open document)

From the mid 1850s through the early 1900s, the white middle and upper class inhabitants of British Columbia persevered in their attempts to solve the ‘servant problem’ and to re-create the British domestic sphere in a new land. Some families emigrated with their British servants in tow. There were repeated efforts to import English girls and women en masse. And many employers were obliged to tolerate ‘strangers’ (Aboriginal and Chinese servants) in their homes. British Columbia’s peculiar ‘servant problem’ ensured that the Imperial vision of employer-servant relations and domestic order could not be exactly reconstructed.
