- Abstract
- The purpose of this study was to investigate and evaluate air quality management strategies and plans in existence today and compare them to the ongoing air quality management planning process in Prince George. The study was conducted by reviewing the literature related to management and control of air pollution, and air quality legislation in Canada, documenting a variety of approaches to air quality management in other regions and administering questionnaires to people involved with air quality. An in-depth case study was completed documenting the attempts taken in Prince George to produce an air quality management plan (AQMP).--Page ii.

- Abstract
- Four mushroom and two lichen species were collected from selected forests in north-central British Columbia and screened for anti-proliferative and immuno-stimulatory activities. All species investigated were immuno-stimulatory with the strongest activity found in the hot water extracts of Laetiporus sp. and Phaeolepiota aurea. Anti-proliferative activity was primarily seen in the ethanol extracts of L. sp., P. aurea, Letharia vulpina, Vulpicida canadensis, and Hydnellum diabolus. Using Sevag extraction method, DEAE Sephadex anion-exchange and Sephacryl S-500 size-exclusion chromatography, an immuno-stimulatory compound was purified from the hot water extract of P. aurea. The purified compound, made up of carbohydrate and protein, has an average molecular weight of 390 kDa. Its carbohydrate component is rich in β-glucan. The compound can stimulate the innate immune system, causing a pro-inflammatory response. Further studies are required to characterize its carbohydrate and protein components in an effort to determine whether it is a novel immuno-stimulatory compound.

- Abstract
- This study examines the efficacy of a psycho-educational group for adults experiencing anxiety and/or panic using cognitive behavioural therapy (CBT) at a community mental health agency. A pre-post design was used to measure target behaviours related to anxiety and/or panic and post-intervention interviews were conducted to explore the service users' experience of the group process, content and outcome. The five pretest-posttest (Self-Rating Anxiety Scale, Anxiety Sensitivity Index-3, Mobility Inventory for Agoraphobia, Quick Inventory of Depressive Sympotomatology and Agoraphobic Cognitions Questionnaire) measure eight target behaviours. Seven of the eight target behaviours for the average client showed significant improved functioning after the group in: (1) affective and somatic symptoms of anxiety (general anxiety), (2) anxiety sensitivity, (3) panic attack intensity, (4) while alone, severity of avoidance behavior of certain common situations, (5) while accompanied, severity of avoidance behaviour of certain common situations, (6) severity of depressive symptoms, and (7) frequency of certain fearful thoughts. The target behaviour, number of panic attacks experienced per week did not show any significant change from before and after the group. For the qualitative interviews, content analysis was used to analyze the verbatim interview transcripts. Seven superordinate themes emerged from the data: (1) joining the group and expectations of the groups, (2) the group experience, (3) coping strategies, (4) strengths, likes and highlights of the group (5) weaknesses, dislikes and low points of the group and individuals suitable or unsuitable for the group, (6) suggestions, and (7) the interviewee's environment. There is a lack of studies investigating the efficacy and service users' experience of group CBT on anxiety and panic in community settings without using strict exclusion criteria. This study is an extension of this research and explored the latter in the context of northern British Columb

- Abstract
- Strong evidence exists that anti-Indigenous racism is built into the fabric of Canadian society and that it is a determinant of Indigenous peoples' health. Colonial policies that historically de-humanized and dislocated Indigenous peoples in order to open territory for European settlement continue to have a negative impact on Indigenous health status today. A mixed methods study combining data from focus groups, individual interviews, participant observation field notes, and surveys explored the use of community-based theatre as a means to ameliorate racism-based health inequities in Saik'uz territory in Northern British Columbia. The findings suggest that community-based theatre provides an effective means for enhancing trust and building relationships within community, and between the traditionally racially divided communities of Saik'uz and the neighbouring District of Vanderhoof. Relationships of trust are crucial elements that contribute to greater well-being for those living in Saik'uz territory. --Leaf ii.

- Women's perceptions of health and well-being in a rural, remote, and resource-dependent community
- Contributors

- Abstract
- This research sought to explore the perceptions of health and well-being for women in a rural and remote northeastern British Columbia community experiencing intense social, ecological, and economic change as a result of its dependence on natural resource extraction. Designed as a qualitative inquiry into the health of local women, this research is informed by social constructivism, feminist theory, and ecosystems approaches to health. Engagement with participants and data collection was heavily influenced by Appreciative Inquiry, a strengths-based approach that identifies assets within a given system with the aim of contributing to positive change. Findings indicate that equitable access, perceptions of people and place, and leadership, communication, and collaboration are factors that strongly impact women’s health and in this context.

- Abstract
- Assessing the shelf life of wood from mountain pine beetle (Dendroctonus pondersoa [Hopkins]) killed lodgepole pine (Pinus contorta var. latifolia) in terms of its compatibility for Portland cement was examined. Two methods of assessment were used, based on the behavior of the exothermic chemical reaction of cement hydration, accounting for the difference between neat cement paste and wood-cement mixtures. A new wood-cement compatibility index meant to integrate current approaches was defined. No evidence was found of limitations in terms of beetle-killed heartwood wood compatibility with cement except for the white rot infested samples. An outstanding physicochemical behavior characterized the mixtures of blue-stained sapwood and cement. Three compositions of ingredients were proposed for fabricating wood-cement boards that would meet the technical specifications given by the gypsum board standards with respect to strength and stiffness. In absence of pressing, the water was the factor used to regulate workability during the molding process.--P.ii.

- The ectomycorrhizal associations of Larix laricina (Du Roi) (tamarack) K. Koch and Betula glandulosa Michaux (scrub birch) seedlings in peatlands of central British Columbia.

- Abstract
- Peatlands are habitats where peat accumulation exceeds decomposition, resulting in poorly drained, nutrient-poor and acidic soils. Tamarack (Larix laricina, family Pinaceae), a deciduous conifer, and scrub birch (Betula glandulosa, family Betulaceae), a low-lying deciduous shrub, are two plant species well adapted to the cold climates and short growing seasons of Central British Columbia and generally able to tolerate the wet, poorly drained soils of peatlands. Ectomycorrhizas are mutualistic associations formed between plant roots and symbiotic fungi ectomycorrhizal fungi that facilitate nutrient acquisition and water uptake in exchange for host carbon, may play an important role in the survival of these species. This study characterized tamarack and scrub birch ectomycorrhizas in three different peatland habitats using morphological (light microscopy) and molecular analysis (PCR-RFLP) methods. Ectomycorrhizal morphotypes and corresponding genotypes (fragment patterns) are described and ideas of host and peatland site specificity are explored. Results suggest that ectomycorrhizal colonization in peatland habitats may be similar to that for other hosts in other habitat types. Both morphology and molecular results indicate a high potential for ectomycorrhizal fungal linkages between hosts. This study presents the first published information on ectomycorrhizal associations of scrub birch.

- Expanding the mine, killing a lake: A case study of First Nations' environmental values, perceptions of risk and health.

- Abstract
- In recent years, uncertainty concerning the long term future of British Columbia's forest industry has led to renewed interest in the mining sector as a means of generating economic growth. However, the development of new operations has raised concerns around the impacts of mining activities on the environment, health and traditional ways of life of First Nations peoples. Using the proposed expansion of the Kemess mine in northern British Columbia as a case study, my research examines two First Nations' perspectives regarding the regulatory process through which environmental values may be validated and protected, and seeks to understand how First Nations' environmental values and perceptions of risk are connected to health and well-being. This case study finds that the environmental values of local populations and the perceived risks associated with resource development are neither well understood nor are they felt to be adequately addressed in environmental impact assessment (EIA) or consultative processes. As a result, health and well-being are undermined. --P.i.

- Abstract
- The Wild Harts Study Area (WHSA) covers an ecological diverse area in northeastern British Columbia that is poorly represented by protected areas. Industrial expansion threatens to fragment the contiguous habitats found in the WHSA — reducing the ability of the area to perform important landscape functions at local and continental scales. I employed a systematic conservation planning approach to prioritize lands for conservation. The software MARXAN with integer linear programming (ILP) was used to produce optimal solutions for conservation, at the lowest cost, and to enforce principles of protected area design. Priority lands for conservation action were those that met science-based targets for a selection of ecological surrogates, displayed low edge-to-area ratios, and represented intact landscapes outside the influence of resource development. The finalized conservation portfolio produced in this research is meant to inform protected area planning in the WHSA.

- Effects of emotional experience in abstract and concrete word processing

- Abstract
- Theories of grounded cognition (Basalou, 2005 Vigliocco, Meteyard, Andrews, & Kousta, 2009) suggest that emotion is a dimension of knowledge important for processing abstract concepts, and to a lesser degree, concrete concepts. Emotional experience (EE) is a variable that has been shown to facilitate the processing of abstract words and inhibit the processing of concrete words in semantic categorization (SCT Newcombe, Campbell, Siakaluk, & Pexman, 2012). The present work extends these findings by examining the effects of EE on abstract and concrete words in lexical decision (LDT), SCT, and semantic lexical decision (SLDT). In LDT, EE exerted facilitatory effects on response latencies for both types of words. In SCT and SLDT, EE exerted facilitatory effects on response latencies and errors for abstract words, but exerted inhibitory effects for concrete words. The results suggest that effects of EE (i.e., emotion knowledge) are dependent on both the nature of the stimuli and task demands. --Leaf ii.

- Carbon budget of forest products harvested from mountain pine beetle-attacked forests in the Prince George region

- Abstract
- The risk of the mountain pine beetle (MPB Dendroctonus ponderosae Hopkins) attacked forests contributing to global climate change has many stakeholders looking for potential mitigation solutions in British Columbia, Canada. To date, these efforts maintain the notion of proactive forest management, yet lack a clear understanding of the contribution of forest products to mitigating greenhouse gas (GHG) emissions. My study addressed this ambiguity by estimating the GHG emissions attributable to current and proposed forest products harvested from MPB-attacked forests. My findings found relative differences between two distinct forest products (lumber, pellets), but ultimately their outcomes are contextually driven. Moreover, the cut-off criteria and assumptions governing biogenic GHG emissions (i.e. carbon neutrality) were found to have a large impact on the industrial forest C budget. The lasting contribution of this thesis is in its reconciliation of the current dichotomy in the fields of environmental science and policy with respect to the contribution of forest products to forestry's efforts in mitigating climate change. --Leaf ii.
