abstract: Face recognition is heavily studied for its wide range of application in areas such as information security, law enforcement, surveillance of the environment, entertainment, smart cards, etc. Competing techniques have been proposed in computer vision conferences and journals, no algorithm has emerged as superior in all cases over the last decade. In this work, we developed a framework which can embed all available algorithms and achieve better results in all cases over the algorithms that we have embedded, without great sacrifice in time complexity. We build on the success of a recently raised concept - Regional Voting. The new system adds weights to different regions of the human face. Different methods of cooperation among algorithms are also proposed. Extensive experiments, carried out on benchmark face databases, show the proposed system's joint contribution from multiple algorithms is faster and more accurate than Regional Voting in every case. --P. ix.

abstract: Biodiversity conservation has been going through a profound change in philosophy, policies and management approaches in the last thirty years. The traditional top-down approach to nature protection has been widely criticized for failing to include critical social elements in management practices, and is being slowly but surely replaced in many parts of the world by a socially more acceptable approach known as participatory conservation. The new conservation approach recognizes communities living in and around protected areas as key partners in wildlife management. However, the experience so far with the application of participatory conservation in protected area management shows that there are shortcomings associated with this strategy, raising questions about the practicality of the approach. In order to gain a better understanding of the approach and its inadequacies, a questionnaire survey of 377 households was employed in the communities in Annapurna Conservation Area (ACA) and Chitwan National Park (CNP) for a comparative analysis of Nepal's two most popular protected areas managed under different policy frameworks and institutional arrangements. The results have identified major differences between the two protected areas in some key elements of participatory conservation, including the level of community participation, motivation factors for participation, and local attitudes toward protected area policies and authorities.'

title: Remediation of  oil-based drill cuttings using low-temperature thermal desorption

format:
electronic
Number of pages in document: 89

abstract: Drill cuttings are generated during the exploration and extraction of oil and natural gas. Due to the use of oil-based muds (OBMs) during drilling process, large amounts of oil-based drill cuttings (OBDCs) are produced. Such hazardous waste contains a relatively high content of petroleum hydrocarbons (PHCs). The effective removal of PHCs from OBDCs has attracted widespread attention since oil contaminants have severe impacts on the plant and animal ecosystem including human health (e.g., carcinogenesis and mutagenesis). Low-temperature thermal desorption (LTTD) treatment which both achieves relatively complete PHCs removal and keeps soil health at the maximum extent represent a feasible and promising method for the remediation of OBDCs. In this study, a bench-scale apparatus was used for the LTTD treatment of OBDCs with different PHCs contents... .

abstract: In this qualitative, action research study a Grade 2 and 3 teacher gathered, implemented, and assessed the effectiveness of teaching literacy strategies to address the literacy needs of a diverse group of students. An additional purpose of the study was to prompt instruction-focused dialogue with colleagues the researcher expected that teachers talking about aspects of teaching and learning could be an important first step in the development of a learning community at the school. The researcher drew on literature related to language theory and practice, current issues in ESL/D education and cultural diversity in the classroom, as well as instructional leadership and school improvement, within a social constructivist theoretical framework. The study was informed by classroom assessment of student attitudes and achievement before and after the implementation of new strategies and approaches. Reflections confirmed that building bridges between the home and school life of students through culturally responsive instruction appeared to enhance students' self-esteem, interest and engagement in learning. The researcher found support for the use of a constructivist perspective to teach literacy by accessing students' prior schema, scaffolding instruction, and providing opportunities for students to make sense of their learning through dialogue. This self-initiated inquiry led to commitment to a literacy program that is built on the principles of culturally responsive teaching and communicative language teaching. Experiences with colleagues during professional development activities on school and district based initiatives pointed out the challenges associated with school reform. Culture and communication were identified as themes that both facilitated and inhibited learning within the classroom and the school. This study may be of interest to classroom teachers, instructional leaders, administrators and school boards officials, as a demonstration of the reflective, classroom-based implementation of promising practices

abstract: Child slavery, composed of child trafficking and the worst forms of child labour, is pervasive in West Africa today. Cote d'Ivoire, a West African country engaged in agricultural production, is a major destination for children to be trafficked and subsequently exploited for their labour. This project investigates how corruption, the abuse of public office for private benefit, enables child slavery to occur. In October 2007, data were collected through semi-structured interviews. Analysis indicates that corruption enables child trafficking, compromises victim protection, and allows for an environment of impunity to reign. Poverty emerges as a pertinent contributing factor to both child slavery and corruption, and dissent emerges regarding the actors responsible for exploiting children. It becomes apparent that corruption is not always needed to facilitate child slavery. This project highlights the need for holistic programming in fighting against child slavery, and recommends further investigation of certain aspects of corruption and child slavery in the West African region. --P.ii.

abstract: The impact of various land use activities (forestry, mining, and agriculture) on the quality of fine-grained sediment (<63 μm) was investigated in the Quesnel River Basin (QRB) (approx. 12,000 km²) in British Columbia, Canada. Samples of fine-grained sediment were collected monthly during the snow-free season in 2008 using time-integrated samplers at sites representative of forestry, mining, and agricultural activities in the basin. Samples were also collected from replicate control sites that had undergone limited or no disturbance in recent years, and also from the main stem of the Quesnel River. Generally, metal and nutrient concentrations for 'impacted' sites were greater than for control sites. Concentrations of As (mining sites), Cu (forestry sites) and Zn (forestry sites) were close to or exceeded upper Sediment Quality Guideline (SQG) thresholds, while Se concentrations for mining sites were elevated and within the range cited for contaminated environments. Phosphorus values were generally <1000 μm g⁻¹ for all land use activities and below available SQGs. Values for individual samples were, however, greater than upper SQG levels, such as 22.7 μm g⁻¹ (As for mining), 5.0 μm g⁻¹ (Se for forestry) and 2192 μm g⁻¹ (P for forestry). Results suggest that metal mining and forest harvesting are having a greater influence on the concentration of sediment-associated metals and nutrients in the Quesnel basin, than agricultural activities. Temporal and spatial differences in the metal and P content of fine suspended sediment within the QRB during the 2008 field season were analyzed using rank sum tests in comparison to discharge (Q) and precipitation (PPT) values. Temporal results suggest the overall mining signature was often a function of changes in activity from point sources, while the diffuse sources, forestry and agriculture, were influenced by variations in transport conditions (e.g. PPT and Q). Spatial variation was greatest between mining and control geochemical concentrations. Forestry and agriculture differed for select elements, but played a lesser role than mining. To further characterize the roles of land uses a sediment fingerprinting method was used, involving stepwise discriminant function analysis (DFA). This resulted in a composite signature capable of differentiating correctly 100% of the source geochemical contributions from each land use type. The composite signature was used to determine the basin-scale geochemical signature using a multivariate mixing model. This determined that agriculture was the highest overall contributor of the sediment signature at the outlet in Quesnel. Additionally, the control influence was strongest earlier in the sampling campaign while mining contributed most in the latter sampling periods. This project contributes to the broader science, and future research in the basin, through a study of multiple land uses in a large basin; a different application of the sediment fingerprinting approach; and a contemporary flume-based sampler evaluation.

abstract: My study focused on investigating wolf-caribou dynamics on the summer range of the Bathurst caribou herd. I used a multi-scale study design to investigate the behavioural and population responses of wolves during a severe decline in caribou numbers. The summer ranges of the Bathurst herd contracted north towards their calving ground as the herd declined and caribou remained farther from the summer territories of wolves for relatively longer portions of the denning period. Density-dependent range contraction of caribou correlated with increase in den abandonment and lower pup recruitment, eventually leading to a decrease in wolf density. At low caribou abundance, variation in wolf movements indicated that prey were more readily available for some packs than others extended movements away from the den in search of prey correlated with higher rates of pup mortality. My results documented a strong numerical response of wolves to a single declining prey base. --Leaf ii.

abstract: Mobility models play a critical role in the simulation studies of Mobile Ad hoc Networks (MANETs). They greatly influence the performance of MANET routing protocols. For MANET simulations, random mobility models have been used in nearly all research studies in the past. In recent times, several studies have criticised the use of random mobility models in the performance studies of MANETs for the lack of realism in modelling mobility. Therefore, questions have been raised regarding the credibility of MANET simulation studies. Realism and simplicity are two attractive properties of mobility models achieving both together in modelling mobility has been a challenging task. Recently, a framework of mobility models called Destination Guided Mobility (DGM) models for MANETs with a basic software tool was proposed. This framework can be used to develop several simple DGM models with improved realism. This thesis is primarily interested in studying DGM models for their suitability in modelling mobility in various MANET scenarios. Our study requires a suitable simulation testbed for DGM models. Designing such a tool, referred to as DGMGen, with suitable functionality to study DGM models is the secondary objective of this thesis. More specifically, after the design and implementation of DGMGen, we study: i) the generality of the DGM models by modelling different real world scenarios ii) the connectivity analysis of three basic DGM models in comparison with the widely used Random Waypoint (RWP) mobility model iii) how to model a real life scenario using DGM models, based on the trace collected from that scenario and iv) the impact of DGM models on the Ad hoc On-demand Distance Vector (AODV) routing protocol using NS2. Our study shows that i) the DGM framework is powerful in capturing various MANET scenarios simply and more accurately, ii) DGM models confirm higher level connectivity prevailed in most real world scenarios, iii) DGM models can generate approximately the similar trace based on the insights of a real trace

subject: GB1399.9.B7 B55 1999

abstract: A growing body of literature is examining the degree of and effects of the flocculation of fine riverine sediments. It has been shown that flocculation changes the morphology of the fine riverine sediment in the water column. The implications of these changes are as yet incompletely understood, but assumed to cause increased sediment deposition. Some recent studies have investigated the effect of pulp mill effluent as a flocculant, but have not satisfactorily ascertained the relationship between the effluent and flocculation. In this study, measurements of the fine sediment morphology upstream and downstream of a pulp mill were compared to measure the effect of pulp mill effluent as a flocculant. The observations were repeated weekly throughout the annual cycle of temperature, sediment concentration and discharge, allowing the effect of the pulp mill effluent to be put into the context of the natural variation of flocculation of river sediments. To measure the actual fine sediment deposition rates with and without the presence of the pulp mill effluent, a series of sediment traps were deployed during low and medium flow conditions. The size fractions trapped in them provided insight into the natural level of deposition and the amount of enhancement associated with the effluent. The data show that the natural size of floes in the Fraser River, as represented by differences in the effective and absolute particle size distribution, is small when compared to results from measurements in other rivers. Floc sizes are larger under low-flow conditions, especially under winter ice. The annual range of floc sizes of the natural sediments(~ 10 um) was much larger than the increase measured due to the presence of pulp mill effluent(~ 1 um). No statistically significant increase in the rate of fine sediment accumulation in the sediment traps was noted due to the influence of the pulp mill effluent, indicating that, at least in the near-field plume (300m), it has no effect on deposition.

Distinguished Cuisines illustrates how the performative consumption of food-as-status leads to a disintegration of character as characters’ senses of self are replaced by reiterated acts of superficial ingestion, ultimately raising particular questions concerning the place of “identity” in contemporary consumer society.

abstract: Exposure to contaminants during pregnancy is associated with certain adverse birth outcomes that require further investigation. Community reproductive and environmental health risk maps were produced utilizing birth data obtained from the B.C. Perinatal Health Program and environmental contaminant data from the National Pollutant Release inventory and other national and provincial sources. Geographical information systems (GIS) were utilized to spatially relate perinatal and environmental hazard data, and the risk of adverse birth outcomes was tested using watersheds as the ecological aggregation unit adjusting for individual-level risk factors. The perinatal data included birth outcomes (low birth weight, prematurity, inter-uterine growth restriction, congenital anomalies, stillbirths) and numerous maternal and antenatal risk factor data for all singleton births in B.C. from 2001 to 2006. Small but significant increased risks of adverse birth outcomes were found in high and intermediate hazard watersheds compared to low hazard watersheds. This suggests a possible environmental effect on these reproductive outcomes, however, further studies are needed to corroborate these results. --P.ii.

abstract: The crux of this thesis is to study the Restricted Quackenbush Problem: if B is a finite algebra of finite type and V(B) is residually finite, must V(B) be residually <N, for some positive integer N? We show that the Restricted Quackenbush Problem is answered affirmatively with respect to unary algebras, a result first shown by Baldwin and Berman in 1975. Then we turn our attention to groupoids and show that all groupoids that generate residually finite varieties must satisfy an identity of the form k(x)≈x∗x, where k(x) is an identity of type {∗} that is not equal to x∗x. Due to this result, we focus on a particular class of idempotent groupoids, called absorbing groupoids. We show that if a certain property holds, with respect to absorbing groupoids, then the Restricted Quackenbush Problem is answered affirmately.

1 online resource (viii, 96 pages)

abstract: I assessed some coastal temperature old-growth forests of southwestern British Columbia to understand their post-wildfire structure, carbon storage and biodiversity values. I used a remotely sensed relativized burn ratio and a composite burn index to compare measures of aboveground carbon, structural complexity and floristic diversity between burned and unburned reference plots years after four large wildfires. The unburned reference plots represented the natural range of variation of old growth values. In burned plots, 21 of 60 retained carbon values and 10 plots retained structural values similar to unburned old growth plots. There was an average of 12% floristic similarity between burned and unburned understory plant communities. For land managers, this method offers a way to compare old-growth values after wildfire in order to prioritize protection, salvage, and restoration options.


title: Gendered representational strategies in erotic literature and screen adaptations: Marquis de Sade and Pauline Réage

electronic
1 online resource (v, 127 pages)

abstract: This thesis explores the relationship between pornography, eroticism, and censorship, focusing on the reception of sexually explicit representations in literature and film by the public and governing bodies in their sociopolitical, cultural, and legal contexts. My comparative analysis of Marquis de Sade’s Justine (1797), its intertextual dialogist, Pauline Réage’s Story of O (1954), and their respective twentieth-century screen adaptations, by Jess Franco and Just Jaeckin, attempts to demonstrate changes in attitudes toward what once was considered to be top-shelf cultural production over time. Drawing on the intersection of cultural, feminist, film, sexuality, and pornography studies, my work examines how, and to what extent, Sade, Réage, Franco, and Jaeckin had their fair share of trouble with censorship laws, and the ways they challenge and subvert the accepted sexual norms and, by extension, then current state body politics by propagating the ideas of sexual freedom, freedom of choice, and sexual equality

abstract: Complexity poses a pervasive challenge in understanding formal and natural systems which can arise from a combination of a system's state and state transition rules. In situations in which many aspects of a system are changing together, it is desirable to quantify how much they do so. We motivate and define five mathematical functions that can be used to quantify coordinated changes in structure. We also developed ConAction, a Python package which implements these novel mathematical tools in a way that is performant, easy to install, and easy to use. These new tools can be applied to real research problems, which we exemplified by evaluating a classic isolation by distance model for Dendroctonus ponderosae populations in western North America


title: The Grey: Emerging identity of the female androgynous hero

format:
electronic
1 online resource (iii, 99 pages)

abstract: Theorists who study the formulation of the hero have identified that the appearance of the hero varies depending on the time and place they are needed. Yet, the function of hero archetypes, such as Joseph Campbell’s monomyth, have reinforced traditional Caucasian masculine male mythic ideologies in young-adult fiction. Reconfiguring the idea of the hero to question its masculine bias and include a female androgynous heroic paradigm will expand the limited classification of “hero” as the hero is encouraged to hone both her masculinity and femininity. This project focuses on a hero with both an androgynous personality and an Indigenous heritage. These aspects of my project push back against the gender and cultural norms often associated with heroic journeys in Western culture. Throughout this thesis, I formulate a more accepting form of identity by mapping an encompassing version of the hero’s journey that pushes the boundaries of classic “heroism” but still utilizes the familiar and effective pattern of the heroic journey of the self by comfortably living in the what I am titling “grey space”. By illustrating the fluidity of identity, young readers can relate to a heroic character who encompasses more than the traditional role outlined by Campbell.

abstract: Ectomycorrhizal (ECM) fungi are symbiotic partners of most conifers and improve host health by increasing access to nutrients and water in return for photosynthates. ECM fungi have been demonstrated to ameliorate the effects of some harsh soil chemical conditions on plants. Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) is found on and off extreme bedrock-derived soils in central British Columbia The objectives of this study were to describe the soils and Douglas-fir forests found on the diverse lithologies of the Fort St. James area and to assess seedling health and ECM fungal communities of Douglas-fir grown on these soils by morphological and molecular means. Fifteen ECM morphotypes, 12 basidiomycetes and 3 ascomycetes were identified with Tuber anniae (Ascomycota) unique to ultramafic soils. Three morphotypes (E-strain, Cenococcum geophilum, and Rhizopogon cf. villosulus) were ubiquitous on all sites and no connection between parent material and ECM communities was established. --Leaf ii.

title: Economic restructuring in resource-dependent communities in the aftermath of mill/mine closure: A comparative case study of Valemount and Tumbler Ridge in northern British Columbia

format:
electronic
1 online resource (xi, 203 pages)

abstract: Beyond the devastating effects on a community, deindustrialization can present an opportunity for change by highlighting the perilous effect of over-dependence on a single industry and motivating local stakeholders to enact change by building social capital and cohesion as well as engaging in local economic development. In small, historically resource-dependent communities, de-industrialization has shifted the focus from staples-based development to a more diverse economy rooted in place-based development. At the same time, the shift from FordistKeynesianism toward Post-Fordist Neoliberalism has limited companies’ obligations toward resource towns as they work through these transitions. Focusing on the case studies of Valemount and Tumbler Ridge, this thesis draws upon a comparative case study approach, key informant interviews, and analysis of documents for a deeper understanding of the processes, strategies, and outcomes regarding this transition. The thesis offers the following findings: First, the shift from a single industry to a diversified economy provides a clear case of a transition towards place-based development. Second, the emerging place-based development trajectory emphasizes the importance of local empowerment and management, strategic investments, social capital/cohesion, local capacity and planning, and government support in transitioning resource towns. Third, the shift from Fordist-Keynesianism to Post-Fordist Neoliberalism has resulted in retrenchment in corporate community development. Additionally, these findings support policy coordination to scale-up social and economic infrastructure, service support, and resources to help maintain place competitiveness and adaptability to future changes. Community transition must be restructured according to local context and needs. Integrating social impact mitigation into the existing BC Environmental Mitigation Policy and permitting process will help foster community sustainability and economic development.


title: Synthesis of metal-organic frameworks as catalyst for the conversion of carbon dioxide to cyclic carbonates

format:
electronic
1 online resource (xi, 76 pages)

abstract:
As more attention is focused on the emission of CO2 into the environment, CO2 produced by industrial sources such as fossil-fuel power plants can be used as a potential source for the manufacturing of useful chemicals. Carbonate synthesis is a general approach for the conversion
of CO2 using epoxides. The reaction of CO2 with epoxides to produce cyclic carbonates requires a catalyst with a high surface area, Lewis active sites, and an affinity for CO2. In this study, copper-based MOF catalysts (MOF-199, Cu-BDC, NH2-Cu-BDC) were synthesized by solvothermal method under mild reaction conditions. These catalysts were characterized by powdered X-ray diffraction, Fourier-Transform infrared spectroscopy, thermal gravimetric analysis, scanning electron microscope, and Brunauer-Emmett-Teller analysis. MOF-199 was subsequently used as a heterogeneous catalyst to catalyze the reaction of CO2 with epoxides to produce value-added cyclic carbonates. More than 65% conversion of epoxides (E1-E4) to the corresponding cyclic carbonates was observed using MOF-199 catalysts (C1, C2-S6, C2-S4, and C2-S6) and TBAB under mild reaction conditions. The conversion to cyclic carbonates was analyzed using 1H-NMR Spectroscopy.

abstract: Planning for community resilience and climate change requires new forms of engagement that are accountable to Indigenous peoples and the social and cultural upheavals associated with colonial harm. This thesis shows that climate governance requires partnerships and policy actions that reflect needs and priorities of communities in specific geographic, political, and cultural contexts. As a case study, it examines the development of the 2020 Our Clean Future (OCF) strategy by Government of Yukon and Indigenous partners. Through semi-structured interviews and document studies, the research applies a theoretical lens of procedural justice and self-determination to the OCF process. Outcomes from this research offer a set of policy cycle considerations and recommendations for future environmental planning partnerships that include taking a rights-based approach, increasing capacity for collaboration in multiple areas, stronger integration of culturally diverse ways of  knowing and doing, and targeted urban Indigenous engagement. Findings suggest OCF can serve as a useful procedural policy tool that supports Indigenous self-determination if lessons learned from the process are carried forward in future environmental planning partnerships.


title: An examination of conceptual knowledge using near-infrared spectroscopy and electroencephalography

format:

abstract: Traditionally, models of conceptual knowledge have relied upon amodal theories that largely overlook how environmental stimuli are converted into amodal representations and how perceptions reactivate these representations and translate them back into subjective modal experiences. Developed more recently, grounded cognition theories propose that physical experiences and conceptual knowledge rely, at least in part, on the same brain regions. Thus, conceptual knowledge is hypothesized to be experienced through the reactivation of the same brain regions that are activated during physical experiences with the environment. Furthermore, if these grounded hypotheses are correct, researchers should be able to observe predictable influences of grounded information on brain activity as well as participant response latencies and accuracy in experimental conditions. To this end, three experiments were conducted testing these hypotheses using semantic categorization tasks while simultaneous recordings were taken using functional near infrared spectroscopy (NIRS) and electroencephalography. It was hypothesized that the influence of automatically reactivated grounded information would be facilitatory (i.e., resulting in faster and more accurate responses for semantically richer words) when it was task congruent, but would be inhibitory (i.e., resulting in slower and less accurate responses for semantically richer words) when it was task incongruent, thus illustrating the automatic simulation of grounded information in the processing and retrieval of conceptual knowledge. NIRS was employed to monitor event-related patterns of prefrontal cortex (PFC) hemodynamics associated with these tasks. It was hypothesized that trials with high levels of task-relevant semantic information would be discernably different than those with low levels or those trials high in task-incongruent information. That is, given the high levels of task-relevant semantic information, these trials should be comparatively easier, thus requiring less activity in the PFC, resulting in less pronounced hemodynamic responses. Electroencephalography was employed to monitor the full-scalp event-related patterns of brain activity associated with the experimental tasks. It was hypothesized that event-related potential deflections and scalp topography would be able to discern qualitatively and quantitatively different patterns of activity as a function of the amount and relevance of grounded information obtained through physical and emotional experiences with the word stimuli’s referents. The behavioural, accuracy, and electroencephalography data generally support these hypotheses. When a stimulus’s grounded information is high and task relevant, participants responded more quickly and accurately, and had discernably different patterns of brain activity than when a stimulus’s grounded information was low and task relevant. When a stimulus’s grounded information was high and task-irrelevant, participants were slower and less accurate, and exhibited patterns of brain activity that reflected both the additional semantic information and the additional processing necessary to reconcile the task incongruence. Unfortunately, data obtained from NIRS failed to illustrate meaningful condition differences. Possible reasons for this are discussed in detail in Chapter 3. Collectively, the data presented in this dissertation serve to advance and extend the claims made by grounded cognition theorists by illustrating the automatic simulation of information obtained through interactions with the environment. Further research is required to extend this work to other brain regions and to develop NIRS methods that can address these research questions.

abstract: Cross-laminated timber (CLT) is becoming a feasible alternative as structural material for midand high-rise buildings. Although CLT walls are appropriate for resisting lateral loads from wind and earthquakes, the current provisions in the Canadian Standard for Engineering Design in Wood lack analytical expressions for estimating their resistance and deflection. In this thesis, the performance of nailed single and couple CLT shear walls is investigated by comparing UNBC test data with the strength and stiffness predictions using analytical proposals. Four methods are considered: Method A (Casagrande et al. 2017), considers the minimum strength value of the hold-down and the vertical fasteners; Method B (Shahnewaz et al. 2019), which accounts for the rocking resistance of all connectors; Method C (Masroor et al. 2020) which accounts for the bi-axial behaviour of connectors; and Method D (Nolet et al. 2019) which describes the elastic-perfectly plastic behaviour of CLT shear walls while neglecting the bi-axial behaviour of brackets. The best match for the elastic behaviour of the nailed shear walls was achieved using Method B, while Method C reasonably predicted the inelastic shear wall behaviour. With the validation against test results, designers should consider using either method depending on the design intentions. Future research should aim at either extending Method B (Shahnewaz et al. 2019) towards the inelastic behaviour or improving Method C (Masroor et al. 2020) in the elastic range.


title: Movement ecology of white sturgeon in the regulated upper Columbia River

1 online resource (xi, 122 pages)

abstract: Advancements in animal tracking technology and analytical techniques have expanded the disciple of movement ecology. An improved understanding of where, when, and why an animal moves can greatly assist in the management and recovery of endangered species. White sturgeon (Acipenser transmontanus) in the Upper Columbia River (UCR) are listed as Endangered due to their considerable decline over the last century. Habitat fragmentation, caused by the construction of dams for hydroelectric generation and river regulation, has greatly impacted white sturgeon populations by preventing access to critical habitat, impacting water quality, and modifying natural flow regimes. The goal of this study was to apply more advanced analytical techniques to white sturgeon movement datasets from a regulated and transboundary reach of the UCR, so as to further understand white sturgeon movement and behaviour in relation to river regulation. Using hidden Markov models (HMMs) and generalized linear mixed models (GLMMs), this study investigated the fine-scale movements of wild adult white sturgeon residing immediately downstream of a hydroelectric operation and the coarse-scale movements of hatchery-origin white sturgeon residing throughout the Transboundary Reach of the UCR. In my fine-scale dataset, two behaviour states were identified: a “residential” behaviour representing short movements with persistent direction, and a “transitory” behaviour representing longer movements with frequent turns. Results revealed that white sturgeon were very likely to remain in a behaviour state, with environmental covariates influencing the probability of a behaviour state only when there was less certainty of the state in the previous timestep (i.e. probability of 50%). Overall, water temperature appeared to influence what behaviour state was more predominantly expressed while discharge appeared to influence where each behaviour state was expressed. Warming water temperatures related to decreased probabilities of residential behaviour and changes in discharge shifted the location of residential behaviour within eddy and tailrace habitats. In my coarse-scale dataset, two behaviour states were also identified: a similar “residential” behaviour state representing localized movement at a single receiver station, and a “transitory” state representing movements between receiver stations. Overall, hatchery-origin white sturgeon moved very little and demonstrated strong site fidelity. When fish did move, location (i.e. country, river zone), discharge, and water temperature had the greatest influence on maximum displacement and behaviour probability. Increases in discharge related to faster declines in maximum displacement in Canada compared to the United States, as well as fish in more channelized river zones having increased probabilities of residential behaviour when previously in a transitory state. Warming water temperatures related to increases in maximum displacement and decreases in the probability of residential behaviour (when previously in a transitory state). In both fine-scale and coarse-scale datasets, trends could be observed seasonally, with increased movement in the summer and fall compared to the winter and spring. Results from this study better described white sturgeon interactions with dams, help describe the effectiveness of recovery measures like conservation aquaculture, and inform management decisions related to river regulation.


title: A study of seasonal variations of traffic collisions and their machine learning prediction model for highways in B.C.

1 online resource (xvi, 291 pages)

abstract: Traffic collisions are considered as one of the world’s major public health problems. According to the World Health Organization (WHO), about 1.3 million people die every year in traffic collisions across the world and a further 20 - 50 million are injured or disabled. Various tools/methods were developed to assess highway safety. Historically, collision frequency, collision rates, linear regression and generalized linear regression, and Bayesian modeling methods have been used as the basis for safety analysis. Research has shown that there are limitations with this approach due to the non-linear relationship between collision frequency and exposure. Traffic volume is directly related to traffic exposure, traffic exposure affects collision risk and collision risk significantly determines the probability of traffic collision occurring. The different traffic exposure has a different level of effects on collision risk, and different level of collision risk results in the different probability of collision occurring and collision severity. Collision prediction modeling (Safety Performance Function) is the recommended technique for estimating road safety in the Highway Safety Manual (HSM) by the American Association of State Highway and Transportation Officials (AASHTO). However, the prediction modeling has not taken into consideration of traffic seasonal variations, collision seasonal variations and weather impacts as the annual average daily traffic (AADT) is one of main dominant variables. Previous studies indicate that weather especially winter weather condition is significantly associated with the traffic collisions. For example, studies showed that 24% of all collisions are weather-related in United States and collision risk could increase from 50 to 100 percent during precipitation. Due to climate change, weather patterns are changing, and the frequency of extreme weather events increases, which will affect highway safety and reliability. This study synthesizes the major findings and proposed methodologies from the existing traffic safety studies. Collision risks related to weather are investigated and assessed. Traditional techniques of highway safety assessment without the consideration of seasonal variations of traffic collisions, especially winter weather condition impacts in Canada, might result in underestimating the safety risk in winter weather conditions. All predication models developed to date have not taken into consideration of traffic and collision seasonal variations, and weather condition. Machine learning (ML) is able to address non-linear relationship between traffic exposure and collision frequency, to handle multivariate data, and to improve over time in the traffic collision prediction modelling. Two major highways (Highways 16 and 97) with a total length of approximate 2,500 km within Northern Region in the Province of British Columbia, Canada, are investigated. This study has mainly focused on the seasonal variations of collisions and traffic volumes to improve the highway safety. A traffic collision prediction model integrated traffic seasonal variations and weather impacts is proposed and developed by applying machine learning (ML) techniques (neural network regression) in the study. In conclusion, the proposed model is able to predict the traffic collision seasonal variations, and to provide more accurate estimate of traffic collisions with over 90% accuracy on both rural and urban highways. The model can be used to assist in developing road safety improvement policy considering collision seasonal characteristics.


title: Linking school based monitoring to land and water decision-making in the Nechako watershed

1 online resource (xi, 174 pages)

abstract:
Climate change is compounding existing threats to waters from land use activities such as forestry, agriculture, and mining, requiring alternative approaches to caring for watersheds. Community science and school-based monitoring are gaining attention as processes for communities and youth to become involved in decision-making by collecting data about the health of their lands and waters. However, due to the complexity of social-ecological systems, connecting community science to decision-making is a recognized challenge requiring more qualitative research that engages various actors. In response, this action-research project aimed to co-design water monitoring tools with students, teachers, and decision-makers to explore potential avenues for school-based monitoring to inform decision-making. The project focused on the case study of the “Koh-learning in our Watersheds” education initiative on Saik’uz First Nation Territory near Vanderhoof, British
Columbia. Research activities took place with high-school classes from the Nechako Valley Secondary School at locations along Murray Creek, a tributary to the Nechako River. Phases of water monitoring actively shaped and informed qualitative research interviews and workshops to bring together youth, teachers, and decision-makers. Pathways identified for school-based monitoring to inform decision-making include: 1) increased attention on waterways, 2) identifying issues and imagining solutions, 3) filling gaps and providing new data, 4) behaviour change and stewardship, 5) contributing to reconciliation, and 6) conversations for action. The findings highlight that the strengths of school-based monitoring lie in its ability to contribute imaginative solutions to local problems that perplex decisionmakers and, when attuned to and aligned with Indigenous governance, can meaningfully support truth and reconciliation. Informed by these findings, an adapted version of the framework for a ‘social learning approach to monitoring’ is proposed and may serve as a tool in the design of future school-based monitoring that can target multiple pathways to influence decision-making. This research underscores that when connecting across knowledges, generations, and linking with decision-making, school-based monitoring can support a paradigm shift in water management.

abstract: This MSW thesis explores workplace value differences as a predictor of healthcare worker professional quality of life. Secondary data analysis was performed on data previously collected on hospice and palliative care workers in a 2013 Pan-Canadian Study. The fit of a theoretically informed model to the dataset was analysed, exploring empirical support that healthcare worker value differences within the workplace accounts for a significant part of the variance in their levels professional quality of life. In the Pan-Canadian study, measures of professional quality of life included the Professional Quality of Life Scale (ProQoL). Additionally, the Nursing Unit Cultural Assessment Tool (NUCAT) was also used. This study reviews the pertinent literature, articulates the model suggested above by exploring existing evidence and theory, and tested the model fit using a structural equation model. Understanding the impact that workplace factors have on healthcare worker professional quality of life is an important area of research. Further research utilizing structural equation modeling may help increase our understanding of the multi-factorial nature of professional quality of life measures and its impact on workers, patients, and families.


title: Impact sound insulation performance of floating floor assemblies on mass timber slabs

abstract: Mass timber buildings become increasingly popular in North America and worldwide. Mass timber panels are mainly used structural slabs in mass timber buildings. However, due to the lightweight and low-stiffness of mass timber panels, the human induced impact sound on floors has been identified as an issue to be solved. Floating concrete topping is a common solution adopted for insulating the impact sound transmission through the mass timber slabs. However, there is few guidance on designing floating concrete floor assemblies and high performance floating floor assemblies for mass timber slabs. In this study, the relationship between concrete topping thickness, dynamic stiffness of elastic interlayers and the impact sound insulation performance of continuous floating concrete assemblies was first investigated according to ASTM test standard. It was found that the floor assemblies with lower apparent dynamic stiffness of elastic interlayer and thicker concrete topping had higher apparent impact insulation class (AIIC) ratings, but limited under 53 dBA without additional floor finish. The empirical prediction equation overestimated the improvements of floating concrete toppings on mass timber slabs. Then, a series of discrete floor raised floor assemblies using elastic mounts were tested using the tapping machine. The results showed AIIC rating of the discrete raised floating floor reached up to 65 dBA. At last, the low frequency (50 to 630 Hz) impact sound insulation performance was conducted according to JIS standard using the ISO rubber ball. With the comparison of sound pressure level (SPL) spectra among ISO rubber ball, ISO tapping machine and real adult walking on both bare floor and different floating floor assemblies, the ISO rubber ball was found to be a suitable source simulating human foot fall noise. The raised discrete floating floor still demonstrated outstanding impact sound insulation performance. However, the correlation between corrected maximum sound pressure level (LFmax) index and apparent impact insulation class (AIIC) was very low. Overall, the floating floor assemblies had similar performance regardless of the type of mass timber slabs as long as the slabs had the same thickness and wood species.

abstract: Managers and care providers in the health sector are expected to deliver safe, efficient and effective services within a resource constrained, complex system. Services are provided through execution of multiple processes. Healthcare organizations tend to be structured in functional based silos with process improvement efforts often focused on individual processes within the discrete silos. This silo based improvement approach fails to take into account upstream and downstream processes executed and managed in other silos. A patient’s journey will typically include processes from multiple silos and therefore, improvement efforts need to focus on end-to-end processes if the goal is to deliver a positive patient experience. In order to optimize processes in a complex adaptive system like healthcare and to effect meaningful change a combination of management disciplines is required. This research explored the use of Business Process Management (BPM), Business Architecture (BA) and Business Process Management Ontology (BPMO) as a comprehensive, integrated approach to design, redesign, evaluate, improve and monitor the safety, efficiency and effectiveness of medication management processes in a multi-site healthcare organization. The contribution of the research was threefold. First, identified benefits of applying BPM, BPMO and BA to increase organization capacity and improve the end-to-end process of medication management; second, demonstrated the application of an ontology and the business layer of enterprise architecture used in other sectors could be successfully utilized in the healthcare sector; and third, developed a process reference model for medication management processes in acute care and long term care facilities.

abstract: In the Central Interior, British Columbia, two trials (in pots and in the field) examined conifer seedlings (lodgepole pine and hybrid spruce) subjected to treatments composed of two ash types (gasifier vs boiler), combined with nitrogen or alone. Two methods of placement, either broadcast spread or burying an ash-filled teabag, and two rates of application (2 tonnes ha-1 and 4 tonnes ha1) were other factors tested. Findings suggested ash fertilization success depended largely on tree species. The gasifier ash, high in mineral content compared to the charcoal-filled boiler ash, prompted the most growth, with and without nitrogen added, and also the highest soil pH increase. The low dose of ash was preferred by both species. Ash placement impacted belowground variables in the seedling pots and, in the field trial, positively influenced spruce growth. Broadcast ash induced the greatest soil pH change, compared to the teabag method.

abstract: A saturated up-flow column experiment was conducted to compare the ability of locally-available organic amendments (hay and sawdust) to foster reducing conditions and attenuate permit-exceeding concentrations of sulfate, nitrate, and selenium in effluent from a British Columbia coal mine. Mine effluent was continuously passed through columns containing one or both amendments mixed with mine-sourced rock, and indicators of organic decomposition and redox conditions were quantified in influent and effluents. Over the 180-day trial, effluent from hay-amended columns exhibited the highest removal of target parameters (up to 99.9%, 98.6%, and 77.5% removal of nitrate, selenium, and sulfate, respectively), although performance decreased over time, suggesting possible long-term performance concerns. In contrast, sawdust-amended columns fostered only partial denitrification and no sulfate removal, which could be linked to the more recalcitrant nature of the organic matrix. Effluents from all columns amended with organics would require further treatment before discharge to a receiving environment.

The need is for a nexus amongst the different fragments of feminism to speak against customs of exploitation and subjugation, but not at the expense of the good culture of the land and in a way not to create loss of identity. To get the message across, some real stories must be told. Aligning narrative craft to share the different experiences that I have witnessed firsthand or told me by the victims of these vast injustices is the focus of this thesis, so the world may learn that there are these experiences and fundamental gender oppressions still exist.

abstract: Many studies purport that Lean is a useful approach to improving quality in healthcare, however, there are calls for better research designs to evaluate its effectiveness. This study used a mixed-methods approach to investigate Lean Rapid Process Improvement Workshops (RPIWs) applied to surgical services in a large health system. The main objective was to conduct an economic evaluation using the Return on Investment (ROI) method. Quantifying improvements at the event level to calculate ROI was not feasible, so the analysis defaulted to examining the cumulative effects of six separate RPIWs at two facilities. The results did not produce sufficient evidence to claim that the outcomes justify the investments. The study went beyond ROI by using various statistical analyses to examine the effects of RPIWs on key performance measures of surgical volumes, sick time, and overtime; with generally non-significant findings. To capture the intangible effects of Lean, key informant interviews explored the richness of participants’ experiences while a survey was used to gather data on experience and engagement from a larger number of participants. The RPIWs produced positive results when considered through a qualitative lens – respondents to the interviews and survey indicated that Lean RPIWs are a desirable method for improving healthcare. Thirteen in-depth interviews yielded six thematic enablers to engagement (a culture of improvement, dedicated time, gradual engagement, improvement interest, social aspects, and participants’ like for Lean). In addition, four themes that represent barriers to engagement were identified (apathy, finances, mis-fit, and resistance). Ten themes also emerged as recommendations for making Lean more engaging. This study contributes to the field by demonstrating the difficultly of empirically calculating the ROI of RPIWs, which leads us to challenge any unfounded claims of monetary benefit from improvement initiatives. It also stresses the importance of qualitatively understanding employees’ experience of Lean and the process of engagement, which is critical for any healthcare organization that wishes to improve its services, client care, and overall performance. The findings invite us to turn our attention away from discussions of financial ROI and toward other evidence that helps us understand how Lean can provide value in healthcare.

abstract: Rivers and lakes are subject to various forms of pollution from anthropogenic activity and natural sources. Many pollutants, such as those from agricultural runoff, are transported in rivers by binding to sediment. Sediment itself is a pollutant, and is often an indicator of terrestrial erosive processes. Common methods of establishing sediment provenance on a broad scale include the use of fallout radio nuclides and geochemistry. In 2008, Dr. Max Gibbs published a sediment tracing article on the use of compound-specific stable isotopes (CSSIs) of plant origin which identified sediment sources based on land use in sub-tropical New Zealand. The objective of the research undertaken here was to apply the CSSI concept to agricultural watersheds in a northern, temperate climate. Two watersheds were selected: the Horsefly River Watershed (HRW) near Horsefly, BC, Canada and the South Tobacco Creek Watershed (STCW), near Miami, Manitoba, Canada. The HRW represented a mostly pristine watershed. The STCW represented a heavily cropped agricultural watershed. The HRW samples were used to develop laboratory methodology, while the STCW samples were used to evaluate the CSSI technique using carbon stable isotopes. The dissertation addresses the following: (i) literature review of plant biomarkers and spatial/temporal variability of CSSIs due to biological, environmental and analytical factors; (ii) methodology, analysis and variability associated with bulk soil and sediment isotope determination; (iii) methodologies for processing soil and sediment from sampling to isotope analysis; and (iv) spatial and temporal variability of CSSI tracers. The CSSI tracers were evaluated to reveal spatial and temporal variability of VLCFA concentrations and isotope signatures at the point, transect and field scales. Weighted t-tests were used to differentiate sediment sources spatially and temporally. The use of bulk carbon as a proxy for VLCFA concentrations in source apportioning was also explored. The work presented here demonstrates the ability of CSSIs to differentiate sediment sources based on land use. The development of analytical methods and the resulting analysis of soil and sediment extracts have indicated that VLCFAs may be isolated and quantified to generate reliable isotope data. The methods will hopefully lead to the standardization of CSSIs protocols.

abstract: Hostility is associated with negative health outcomes. Empirical research has indicated that high levels of hostility, in association with personal characteristics, may result in either aggressive actions and re-actions, or isolation and disengagement. The purpose of this study was to investigate hostility and its influence on mental health, overall satisfaction with life, job, and marital relationship, and cardiovascular health of professional firefighters. The study was analyzed in the context of Social Ecology Theory exploring how personality, spousal relationship, and social factors influenced the relationship between work and health. Firefighters were invited to engage their romantic partners in the study assessing how work stress impacted intimate relationship. Data analyses involved structural equation modeling, as well as repeated measures multivariate analysis of variance and multilinear regressions. The results indicated that work stress and exposure to toxic environment and hazardous conditions have a negative impact on the mental health and overall satisfaction of firefighters, but not on hostility. When controlling for personality, openness to experience revealed a significant relationship between work and hostility. No significant relationships were observed either between hostility and domestic conflict or between hostility and cardiovascular health.

abstract: Splicing is an interesting step in the processing of the precursor messenger RNA (pre-mRNA) that involves removal of the non-coding sequences (introns) and ligation of the coding sequences (exons). 50% of genetic diseases exert their effects through errors in splicing (López-Bigas et al. 2005). Therefore, a better understanding of this process can ease the development of cures for these diseases through genetic therapy. I proposed to investigate splicing in Cyanidioschyzon merolae that possesses a simpler spliceosome comprised of four snRNPs and 68 splicing proteins. I present successful expression of the Dib1 protein, and co-expression and purification of the Sm complex. I was able to prove formation of the ring-shaped Sm complex by electron microscopy analysis and binding of the complex to U2, U4, and U5 snRNAs. This work also initiated an investigation of splicing as a vital process for C. merolae by blockage of this mRNA maturation step with morpholino oligonucleotides.

abstract: Moose are a keystone species and play a substantive role in predator-prey systems, nutrient cycling, and forest succession. Following a mountain pine beetle (MPB) spread across British Columbia, I quantified seasonal home-range selection, home-range size and daily movements, and within home-range selection of GPS-collared female moose in three study areas. I used case-matched logistic regressions with individual seasonal home-ranges, and mixed-effects logistic regressions for seasonal locations of female moose to determine habitat selection at two spatial scales. Individual variation was evident at both home-range and within-home-range scales. Female moose selected lodgepole pine-leading stands at both spatial scales regardless of mass die-off due to MPB. Clear-cuts following the MPB outbreak were avoided in drier locations, and trade-offs between cover and browse were evident where disturbance due to salvage logging was highest. My findings indicate that MPB salvage-logging reduced moose habitat, and thereby, influenced selection by female moose.

abstract: Food webs are challenging to describe, particularly for generalist predators whose diet consists largely of taxonomically diverse invertebrates. To better understand predator-prey relationships for fish belonging to Salmonidae and Cottidae, I compared traditional morphological identification of prey with sequencing of individual items and next generation sequencing of fish stomach homogenates. I also used next generation sequencing to assess invertebrate biodiversity from environmental DNA samples – stream water, ethanol preservative from Surber samples and fish stomach homogenates. Morphological identification was often limited to the Order level but allowed for quantitative data. Genetic analysis provided substantially greater taxonomic resolution, with sequencing of stomach homogenates revealing a much more diverse diet in fish. Water samples detected terrestrial and aquatic invertebrate species and Surber ethanol revealed a similar invertebrate diversity as fish stomach homogenates. Fish, however, appeared to be generalist feeders and collectively accounted for the greatest number of unique taxa.

the local and regional wind fields. Quesnel Lake, nestled into the western flank
of the Cariboo Mountains in central British Columbia, is one such lake. This study examines
the wind climatology of Quesnel Lake at three distinct spatial and temporal scales.
Firstly, long-term wind data from meteorological stations bordering the Cariboo Mountains
exhibit a cycle of calm and active periods throughout the year. Secondly, an environmentto-
circulation synoptic climatology is presented that illustrates the large-scale atmospheric
patterns that lead to strong wind events at the lake. Finally, the spatial and temporal variability
of the near-surface wind field has been examined using an array of shore-based
meteorological stations. The response of the wind field to synoptic forcing is found to be
driven primarily by the orientation of the regional 800 hPa pressure gradient.

abstract: This thesis examines three Gothic novels: The Romance of the Forest and The Mysteries of Udolpho by Ann Radcliffe and Northanger Abbey by Jane Austen. In these three novels, the female heroines of each struggle against the patriarchal power structures of eighteenth-century society. Immersion in a natural environment strengthens these female Gothic heroines, aiding them to resist the will of male characters and to establish agency. Gothic nature is an ally to women, while Gothic urban settings act as a domain of oppression for both women and nature. The authors Ann Radcliffe and Jane Austen wrote active heroines who in turn influenced female readers. These novels and their heroines were an active influence on feminist thought and ideas in eighteenth century England.

abstract: Hospice care can improve quality of life for persons nearing end of life. Little is known about hospice care practices in long-term care facilities (LTCFs) in Canada. This thesis included 185,715 residents in LTCFs in Canada in 2015 and followed their death records to 2016 to examine the characteristics of residents who received hospice care and those who did not but may have benefitted from it. Univariate, bivariate and multivariate analyses were used depending on the variable type. Results show the actual use of hospice care in LTCFs is very low in Canada (i.e. less than 3%). Residents who received hospice care had more severe and complex clinical needs than those who did not. Findings suggest several possible barriers to hospice use in the LTCF population including ageism, rurality, and disease diagnoses. Immediate action is needed to provide improved access to, and utilization of, hospice care in LTCFs in Canada.

abstract:
The first part of this thesis investigated the growth-inhibitory and immunomodulatory potential of six wild Canadian mushrooms. Out of 24 crude extracts, six showed strong growth-inhibitory activity, two exhibited strong immuno-stimulatory activity and nine demonstrated potent anti-inflammatory activity.
The second part of this thesis involved purification and characterization of growth-inhibitory compounds from Albatrellus flettii. Liquid-liquid extraction, Sephadex LH-20 and HPLC-Mass Spectrometry (HPLC-MS) were used to purify the three compounds of interest. NMR analyses confirmed their identity as grifolin, neogrifolin and confluentin. Grifolin and neogrifolin inhibited IMP1-KRas RNA interaction as demonstrated using an in-vitro fluorescent polarization assay. The three compounds suppressed KRas expression in SW480 and HT-29 human colon cancer cells. Confluentin, shown for the first time, to induce apoptosis and arrest cell cycle in SW480 cells.
The third part of this thesis involved the development of methods to purify growth-inhibitory compounds from Sarcodon scabripes. HPLC-MS detected some potential novel compounds.

abstract:
Snow plays an important role on the hydrological cycle of watersheds in cold regions. Predicting timing and magnitude of snow accumulation and ablation is necessary for water management in different sectors.
A spatially distributed snow model (SnowModel) is chosen for our research, which is forced by meteorological data provided from automated weather stations. SnowModel is evaluated for two watersheds in southeast of BC. Two consecutive year (2006-2008) are selected for the calibration and validation processes. Simulated snow depth and snow water equivalent (SWE) are compared with observed data from snow pillows.
Two error factors of Nash-Sutcliffe Efficiency Index, and R-squared show 0.96, 0.98 values in accumulation period and 0.87, 0.86 for ablation period, respectively. Spatially distribution of snow depth and SWE over domains also are discussed. In general, SnowModel is able to estimate the accumulated snow depth and SWE in alpine areas in a high level of accuracy.

subject: BC Biocarbon

abstract: Biochar, a form of black carbon produced from pyrolyzed biomass, has been touted as a product that may suppress agricultural soil emissions while also sequestering carbon. BC Biocarbon LTD, a recently established company in McBride, BC, has developed a method of producing a new product called biocoal. This biocoal is produced from a combination of crushed biochar and an organic-based binder also made from the original biomass feedstock. As their biocoal contains similar properties to fossil coal or petroleum coke, its use to reduce emissions as an energy fuel or sequestration method may be favourable to biochar’s use as a soil additive. Additionally, this biocoal may present a method of long-term carbon sequestration if buried. This dissertation assessed the greenhouse gas emissions from the production of biocoal from BC Biocarbon’s system and compared the results to wood pellet production and delivery (Project 1), coal and petroleum coke displacement (Project 2), landfilling for carbon sequestration, while also assessing biochar’s potential soil greenhouse gas reductions with added carbon sequestration (Project 3), and a regional and province-wide assessment for reducing emissions in BC using available sawmill and roadside slash residues (Project 4). Project 1 showed that when comparing biocoal made from sawmill residues to locally produced wood pellets, transportation emissions may be decreased 64% due to biocoal’s higher heating value. When comparing emissions produced for biocoal or wood pellets at gate, biocoal may show a 42% reduction in emissions or up to a 51% increase in emissions, however this is largely dependent on the data-sourced scenarios and their underlying assumptions of emissions allocation. Project 2 showed that displacing petroleum coke in cement kilns offered the largest reduction potential compared to coal applications such as electricity generation, or lead smelting. Project 3 showed that under 3 average conditions, sequestering biocoal offered greater emission reduction potential than soil applied biochar. Finally, Project 4 showed that an estimated GHG emission reduction or carbon sequestration of 28,000,00 Mg CO2e/year from current available residues, and 20,006,000 Mg CO2e/year in 10 years’ time, BC has the potential to reduce its current emissions by around 46%, and 33% in 10 years.

title: The potential of novel phenol-derivative compounds for feeding deterrent control of several stored-product coleopteran pests

subject: Food storage pests--Control

abstract: The development of new tactics for the management of stored-product insects is important as more conventional methods may becoming less effective due to pesticide resistance and the increasing interest in developing chemical control options with fewer of the negative side effects (e.g., environmental and health impacts). I screened several libraries of phenol-derived compounds with varying substitutions and substituents for their potential as feeding deterrents and insecticides using flour disk no-choice feeding bioassays against a total of five species of stored-product coleopteran: Tribolium castaneum, T. confusum, Sitophilus oryzae, S. zeamais, and Rhyzopertha dominica. By using structurally similar compounds, I was able to determine some structure-activity relationships, in particular meta- and para-substituted rings with mid-sized substituents showed the highest feeding deterrent activity. I was also able to show that while there where some similarities in both feeding behavior and mortality between the closely related species, there were also differences which highlights the importance of not extrapolating behavior even to closely related species. There was also evidence that, in general, the primary pests (S. oryzae, S. zeamais, and R. dominica) showed more sensitivity to the test compounds compared to the secondary pests (T. castaneum and T. confusum), which may be explained by looking at these species as specialist and generalist feeders. Finally, during the course of the experiments, an alternative method of measuring feeding in the flour disk bioassays was developed (surface area) and compared to the established method (weight). The methods are comparable and surface area analyses may be a less expensive, alternative way of measuring feeding in some scenarios. Ultimately I was able to identify several compounds that show potential to be feeding deterrents for some stored-product coleopteran pests without significant mortality.

abstract: It is a pivotal time in cervical cancer prevention for young South African (SA) women. Cervical cancer and infection with human immunodeficiency virus are both major public health concerns in SA. This study describes knowledge of female adolescents and young adults (AYA) about HPV, cervical cancer and explores predictors of HPV vaccine and HPV self-sample testing acceptability. In this cross-sectional study, questionnaires were administered to 122 female AYA who involved in a longitudinal study (AYAZAZI) which examined risk factors involved with HIV acquisition. Results indicated that although awareness and knowledge about these topics was very low among participants, as were perceptions of risk of acquiring HPV and developing cervical cancer, acceptability was very high towards HPV vaccines for self (97%) and (future) children (95%), as well for self-sample testing (85%). No significant variables were found to be associated with risk perception or self-sample acceptance. A significant difference was found between participants’ perceived risk of acquiring HPV, HIV, and developing cervical cancer compared to the risk they felt other female AYA in their communities were at. The most influential sexual and reproductive health (SRH) information source and significant influences on HPV vaccine recommendations for participants were health care providers. Findings from this study are important in designing effective cervical cancer control programs that can attract more AYA for HPV vaccines and screening. As the HPV vaccine has only recently been introduced at a national level in SA, this study about awareness and vaccine acceptability is timely.

Lodgepole pine--Diseases and pests

abstract: Dothistroma septosporum Dorog. Morelet is an emergent fungal pathogen of pine responsible for increasingly severe and widespread damage in British Columbia. Native lodgepole pine (Pinus contorta var. latifolia) is considered highly susceptible, but has been extensively planted due to its commercial value. Current management options involve either avoidance or species diversification. Quantitative resistance to Dothistroma has been observed in several pine species, and further identification of resistant lodgepole pine varieties is important for future management of the disease. My objectives were to determine the historical climatic influences on constitutive foliar terpene levels, identify foliar secondary metabolites associated with resistance and historical disease pressure, and to ascertain the in vitro effects of these compounds. I quantified foliar secondary metabolites from both seed orchard and resistance trial lodgepole pines, many of which were identified as terpenes. I quantified the Dothistroma outbreak history of lodgepole pine provenances using dendrochronological methods, and the climate history of these provenances using an interpolated historical climate model. I found that constitutive foliar levels of specific terpenes significantly correlated (P<0.05) with climate at provenance origin, Dothistroma resistance, and provenance outbreak history. I assessed the in vitro effects of the sesquiterpene alcohol (E,E)-farnesol on various D. septosporum isolates. Temperature normals at provenance origin were significantly negatively correlated with foliar terpene levels in orchard trees. Family crown retention variables were significantly positively correlated with levels of a number of sesquiterpenes and sesquiterpene alcohols. Provenance Dothistroma outbreak history was significantly positively correlated with levels of a wide range of monoterpenes, two sesquiterpenes, and two sesquiterpene alcohols. In vitro effects of the sesquiterpene alcohol (E,E)-farnesol were complex, with the compound conferring growth inhibition at high concentrations and stimulation at low concentrations. My results indicate that foliar terpenes play an important role in quantitative resistance of lodgepole pine to Dothistroma septosporum, and this work provides a basis for future investigation into the defensive role of these compounds. A more comprehensive knowledge of the Dothistroma-Pinus relationship is required for future identification of resistant lodgepole pine varieties, and to further our understanding of the forces driving emergence of this damaging fungal pathogen in British Columbia.

abstract: Complex trauma is a critical area to explore in terms of the emotional, physical, psychological, social, and spiritual well-being of survivors. This research explored the personal experiences of 12 adult survivors of childhood trauma by interpreting the meanings they attach to their stories of healing. A three phase analysis approach adapted from the work of Lieblich, Tuval-Mashiach, and Zilber (1998) was carried out. Individual interviews were analyzed following a narrative approach to capture each participant’s perspective and meaning. The themes that emerged from the narratives were organized into ten main categories. Five overarching metathemes occurring across all of the participants’ narratives included: Trauma Effects, Establishing Safety, Reclaiming Self, Healing through Relationships, The Healing Journey. The results of this study add important findings that increase understanding of how to address complex trauma in counselling and health care settings in order to restore individual’s sense of safety and well-being. By targeting the possible issues linked to the seven domains of complex trauma that underlie the presentation of traumatized individuals, survivors will feel more supported in their recovery and may be more likely to access appropriate support.

abstract: A large (~25 M m3) copper-gold tailing spill occurred in 2014 at the Mt. Polley Mine, which released solid and liquid waste and caused a debris flow into nearby Polley Lake and Quesnel Lake. This study examined the spatial and trophic patterns of trace elements in water bodies impacted by the spill between April and November 2016. Concentrations of trace metals in biofilm, invertebrates, sediments, and water were measured and analyzed using DGT and ICP-MS. Trophic positioning of sampled organisms was established using invertebrate functional feeding groups, and stable isotope ratios. Spatial results indicated that copper and vanadium concentrations in biofilm and invertebrates at impacted environments regress significantly with distance to the spill. Trophic results show evidence of copper bioaccumulation and selenium trophic magnification in biofilm and invertebrates from impacted waters. These effects appear to have seasonal variations, with stronger trophic and spatial relationships during spring overturn of Quesnel Lake.
