Attempts to limit suburban sprawl by publicizing its social, economic, environmental, and health problems have not been effective. An important aspect of this ongoing appeal of sprawl is its promise of ideal community. The discourse of ideal community in advertisements for housing developments in the Okanagan Valley, British Columbia. echoes discursive constructions by Plato and Aristotle, Rousseau and Kant. Sprawl is therefore another attempt to solve a problem in political thought that originates with the polls, namely, how to envision, authorize, construct, and secure the best possible space, form, and practice of human organization. By constructing secure political community as the physical embodiment of metaphysical truth, a necessary but impossible resolution between nature and culture, this discourse constructs the central problem of politics as unsolvable. Thus the intractability of sprawl needs to be understood as a political problematic where the act of imposing a solution regenerates the original problem.

This thesis argues for a more expansive historiography rooted in Indigenous peoples’ oral, social and land-based modes of sharing knowledge. Such an approach may help to decolonize the practices and narratives of history in British Columbia, which have too often excluded or undermined Indigenous peoples' perspectives. Over the past several centuries, Indigenous knowledge-keepers have used their languages to maintain their oral traditions and other modes of sharing, despite colonial policies in Canada aimed at destroying them. This thesis gives careful consideration to ethical approaches to cross-cultural engagement, including researcher’s position in discourse and colonial paradigms, as well as modes of listening that emphasize attitudes of respect, flexibility, responsibility and trust-building. I travelled to Syilx (Okanagan) territory in south central British Columbia to interview five knowledgeable Upper Nicola band members about their knowledge practices. Their views, combined with those of others (from Nlaka’pamux, to Coast Salish, to Maliseet peoples and more) pointed to the importance of a vibrant Indigenous historiography at the local community level. Interviewees discussed the ways speaker/listener relationships, as well as timing and life experience, shape knowledge passed on. They also explained the ways Indigenous knowledge practices are linked to particular territories, as knowledge may help to sustain or may be sustained by particular places. Lastly, all touched on how colonial policies have impacted their knowledge practices. This thesis proposes some decolonizing approaches for engaging with Indigenous knowledge and knowledge practices. By accounting for Indigenous knowledge 'institutions' that have long existed outside of colonial frameworks, we can move one step closer to decolonization. / Graduate

Over the course of the 20th century, the type of farm labour desired by the North American agricultural industry and the strategies used to procure that labour have undergone significant changes. Rather than relying on immigrant or domestic workers, many growers are now choosing to import temporary foreign workers under contract programs such as the Canadian Mexican Seasonal Agricultural Worker Program (MSAWP). This thesis discusses the implementation of the MSAWP in British Columbia's Okanagan Valley, a region that has for many years depended upon the labour of migrant Quebecois workers to harvest its crops but has for several years experienced severe agricultural labour shortages. Based on fieldwork which explored the experiences of Mexican and Quebecois migrant farmworkers in the Okanagan. it is suggested that the valley's labour shortage has largely been created by the agricultural industry and government, neither of which have improved the conditions of farmwork to the point where agricultural labour would appeal to Canadian workers, and that the MSAWP's implementation has a number of implications, both positive and negative, for agricultural labourers and farmers in the valley.

The range of a species often extends across a diverse landscape, necessitating that individuals make different movement and habitat decisions, despite consistent food and shelter requirements. Great Basin gophersnakes (Pituophis catenifer deserticola) are threatened in Canada, where they occur at the northern extent of their range in southern interior river valleys of British Columbia such as the Okanagan Valley. I followed 39 radio-transmittered adult gophersnakes at four sites in the Okanagan, to obtain information on life history, movement and range patterns, and habitat use. Habitat selection and movement patterns exhibited by gophersnakes differed between study sites, sexes, and months, indicating that snake choice varies depending on resources and life history traits. Despite these fine-grain differences, males moved more than females in the spring. In addition to this, females moved more than males in the summer and fall. Differences in movement and range were apparent among the study sites. Habitat selection differed by study site, however rock-outcrops were consistently selected overall. Microhabitat selection varied, but retreat sites including logs, rocks, and holes in the ground, were consistently located closer than random. Hibernation sites in the south Okanagan were in rock features, while in the north Okanagan a good proportion were in rodent burrows in hillsides. Hibernation site fidelity was low, and annual reproduction was common. Oviposition sites were on south-facing slopes of moderate grade with little to moderate grass cover. Three ecdysis periods were observed when most or all transmitter-equipped snakes shed their skin. These findings will be very valuable to species conservation goals in British Columbia when developing guidelines on the habitats and sizes of areas to protect. With an iii understanding of the movement and ranges patterns exhibited by individuals, the area required to sustain a healthy population of gophersnakes can be determined. Knowledge of the habitats and microhabitats gophersnakes select makes it possible to identify and protect important areas at sites known to contain gophersnakes, including the Vaseux, Ripley, and Vernon study sites. Characterization of hibernation and oviposition sites allows surveys to identify these areas in locations that may support gophersnakes. Finally, identification of the timing of various important life history behaviours means human disturbance can be avoided during mating and oviposition periods, especially on sites such as Vernon, where land is used for multiple purposes.

Snow surface energy balance was studied along an elevational gradient and under varying forest cover types during the ablation season of 2007 in the Coldstream Basin, Okanagan, British Columbia, Canada. During the snowmelt period, 1-4% of the peak annual snow-water equivalent (SWE) was lost to sublimation in open sites – averaging 0.4 mm d-1. Melt and sublimation rates increased significantly with elevation, and were higher and more variable in the open sites than under forest canopies. Melt rates were driven almost entirely by sensible heat fluxes and exceeded 30 mm d-1 during large-scale advection events. The melt and sublimation processes observed at the snow surface were significantly linked to conditions in the atmospheric boundary layer. From these linkages, a proxy record of historical ablation season energy fluxes for the period 1972-2007 was created. Significant trends towards earlier dates of snowmelt and freshet onset were detected, as was a trend towards increasing ablation-season temperatures at the 850 mb height. Significant correlations between estimated historical ablation-season melt and sublimation and the regionally dominant teleconnection indices were also found. This study significantly advances the understanding of ablation season snow-surface energy exchanges, and the links to the driving atmospheric conditions in the Okanagan Basin.

Melanie Jones and Dan Durall aren't looking to the treetops for clues about the "wood wide web." They're looking to the soil at fungi that are crucial to renewing our forests.

Using Indigenous methodology and a story telling method this thesis is the result of research that looks at the benefits of traditional Indigenous ceremony and healing practices as a way to heal from traumatic experiences. A thematic analysis technique was employed to reveal four themes that emerged from the stories told by Indigenous Knowledge Keeper participants. The first theme is the importance of our connection to all living things including our own selves. Another is recognizing our greatest teachers nature and animals. Cleansing emerged at the center of all traditional healing strategies and the final theme encompasses all that we are as life on this planet spirit or energy. Trauma can be understood as any event that creates difficulty for the individual to cope whether the event that caused the experience was purposeful or accidental. While people do find amazing ways to cope with circumstances that are overwhelming, neurobiology tells us how trauma is processed and impacts the workings of the brain. Trauma in the nervous system can be understood as the result of a person or group or community’s inability to stay safe or to feel safe during the experiences. Indigenous people live with the ongoing effects of intergenerational trauma caused by colonization including the Indian Residential School experience, as well as ongoing systemic oppression. All traumas can activate the deeply held traumas that have been transmitted trans-generationally. In essence we carry intergenerational traumas. I believe that Indigenous people were practicing healing on a regular basis within their traditional ceremonies, dances and practices before contact and these practices may inform a model of health and wellness that could be useful in healing the effects of trauma that impacts Indigenous people today. Ceremonies and traditional teachings were shared communally before contact and are now being revived as we embrace the cultural practices of our ancestors across this land. Within our Indigenous ways of knowing we recognize that we are related to everything in creation we are connected and depend on one another. In 1884, under the Potlatch Law & section141 of the Indian Act our ceremonies, spiritual practices and traditional knowledges were made illegal; our people were imprisoned for practicing them (UBC First Nations Studies, 2009). Today we are in a state of desperation for healing strategies that work for who we are as a people. The Elders in this research shared how this can be done. / Graduate / 0452 / 0622 / 0347 / sheilanyman@shaw.ca

Considerable attention has focussed on identifying individual factors associated with, or predictive of, sexual offending (e.g., Efta-Breitbach & Freeman, 2004). In light of these individual factors, clinicians and researchers have developed standardized instruments for assessing the risk posed by sexually offending youth. Two such instruments are the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II; Prentky & Righthand, 2003) and the Estimate of Risk of Adolescent Sexual Offence Recidivism Version 2.0 (ERASOR-II; Worling & Curwen, 2001). In addition to individual factors, research on crime has demonstrated that structural factors within the community may be important determinants of sexual and non-sexual offending (e.g., McCarthy, 1991; Ouimet, 1999; Shaw & McKay, 1942; Wirth, 1938). Therefore, the purpose of this study was twofold: (a) to compare the psychometric properties of two newly developed risk assessment instruments (i.e., J-SOAP-II and ERASOR-II) and (b) to use the better instrument to compare the levels of risk posed by sexually offending youth in 3 neighbouring, but diverse communities. Using file information, the J-SOAP-II and ERASOR-II were scored on 84 adolescent males between the ages of 11 and 20 years who had committed a sexual offence and received treatment at Youth Forensic Psychiatric Services (YFPS) in the Greater Vancouver Area (GVA; n = 30), Central Okanagan (CO; n = 26), and Thompson Nicola region (TN; n = 28). Calculations of interrater reliability and item-total correlations indicated that the J-SOAP-II was a better assessment instrument for this sample of offenders. Consequently, further regional analysis of risk was conducted using the J-SOAP-II data. Results indicated that although there were no regional differences among the severity and history of sexual offending, TN youth generally had a greater number of risk factors than did youth in CO and GVA. Specifically, youth in TN were found to be higher risk in the areas of intervention, general problem behaviour, iii and family/environment dynamics. These results suggest that to better understand youth who commit sexual offences and to provide appropriate prevention and intervention strategies for individual offenders and their communities, youth should not be evaluated in isolation from their social and community context. Recommendations for practice are discussed.
