description: The first part of this thesis presents a Bayesian penalized spline approach to constructing smooth forward curves in electricity markets. Since electricity should be delivered as a continuous flow, power contracts have settlement periods rather than a fixed delivery time. In addition, electricity forward curves have strong seasonal shape. Our approach provides a method for estimating a continuous forward price curve from market forward prices quoted over a period. The approach is illustrated using observed market data from the Mid-Columbia (Mid-C) and California Oregon Border (COB) pricing hubs. Since Mid-C is a liquid market where forward contracts are quoted every day and COB is an illiquid hub, a two step estimation procedure is developed from Bayesian perspective.First, the Mid-C smooth curve is constructed using Bayesian penalized spline. Next, the COB smooth curve is estimated by adding a spread to the constructed Mid-C smooth curve and incorporating the positive spread between the two hubs as an informative prior. In the second part, we present a mean reverting model for the electricity spot price and we employ a Bayesian penalized spline approach to model the deterministic seasonal function exhibited in the monthly averages. Based on the historical spot price from Alberta power market, we calibrated the model parameters, also by implementing Bayesian estimation techniques.

description: Soft-clamped silicon nitride membrane resonators reach coherence times tau in excess of 100 ms at milliKelvin bath temperatures. However, harnessing strong optomechanical coupling in dry dilution refrigerators remains challenging due to vibration issues and heating by optical absorption. Here, we propose to address these issues with an actuator-free optical cavity and mechanical resonator design, in which the cavity is mounted on a simple vibration-isolation platform. We observe dynamical backaction when the cavity is driven with a free-space optical beam stabilized close to the red sideband using a two-beam locking scheme. Finally, we characterize the effect of absorption heating on the coherence time, and find a scaling with the intracavity power P as tau proportional to P to the power of -(0.34+/-0.04).

description: We have carried out a wide study of shadowing and antishadowing effects on \jpsi\ production in \dAu\ collisions at $\sqrt{s_{NN}}=200$ GeV. We have studied the effects of three different gluon nPDF sets, using the exact kinematics for a $2\to 2$ process, namely $g+g\to J/ψ+g$ as expected from LO pQCD. We have computed the rapidity dependence of \RCP\ and $R_{d\rm Au}$ for the different centrality classes of the PHENIX data. For mid rapidities, we have also computed the transverse-momentum dependence of the nuclear modification factor, which cannot be predicted with the usual $2\to 1$ simplified kinematics. All these observables have been compared to the PHENIX data in \dAu\ collisions.

description: The testing of complex adaptive systems for emergent misbehaviours currently lacks any kind of automated support. In this thesis, we present Incremental Adaptive Corrective Learning, an evolutionary learning technique which automatically identifies vulnerabilities and performance-limiting behaviours induced by adversarially controlled agents inserted into a tested mobile ad-hoc network. Three case studies are presented, each demonstrating how Incremental Adaptive Corrective Learning is used to induce poor network performance in different mobile ad-hoc network applications.

description: We present a detailed study of the production of dark matter in the form of a sterile neutrino via freeze-in from decays of heavy right-handed neutrinos. Our treatment accounts for thermal effects in the effective couplings, generated via neutrino mixing, of the new heavy neutrinos with the Standard Model gauge and Higgs bosons and can be applied to several low-energy fermion seesaw scenarios featuring heavy neutrinos in thermal equilibrium with the primordial plasma. We find that the production of dark matter is not as suppressed as to what is found when considering only Standard Model gauge interactions. Our study shows that the freeze-in dark matter production could be efficient.

description: We study the relation between process calculi that differ in their either synchronous or asynchronous interaction mechanism. Concretely, we are interested in the conditions under which synchronous interaction can be implemented using just asynchronous interactions in the pi-calculus. We assume a number of minimal conditions referring to the work of Gorla: a "good" encoding must be compositional and preserve and reflect computations, deadlocks, divergence, and success. Under these conditions, we show that it is not possible to encode synchronous interactions without introducing additional causal dependencies in the translation.

description: There are many commercial information visualization tools that enable domain experts to create visualizations on their own. However, when the data and the domain is complex, the visualization design task is delegated to a visualization designer. In this case, the visualization designer works in close collaboration with domain experts and their knowledge of the domain evolves through prototyping visualizations. The visualization prototypes are designed programmatically or on paper. Therefore, we propose that visualization designers and domain experts should create visualizations together using a visualization tool. These visualization design activities can lead to discussion and criticism on existing representations and serve as important usability criteria for more useful designs. We designed PairedVis, a tool to support both experts, the visualization designer and the domain expert in creating visualizations together. We conducted a study to investigate whether PairedVis supports the two experts in sharing knowledge and discussing representations.

description: We show that to explain the growth of the citation network by preferential attachment (PA), one has to accept that individual nodes exhibit heterogeneous fitness values that decay with time. While previous PA-based models assumed either heterogeneity or decay in isolation, we propose a simple analytically treatable model that combines these two factors. Depending on the input assumptions, the resulting degree distribution shows an exponential, log-normal or power-law decay, which makes the model an apt candidate for modeling a wide range of real systems.

description: Motivated by recent experiments [Nat. Phys. $\textbf{16}$, 1227 (2020)], we present here a theoretical study of the DC Josephson effect in a system comprising two magnetic impurities coupled to their respective superconducting electrodes and which exhibit Yu-Shiba-Rusinov (YSR) states. We make use of a mean-field Anderson model with broken spin symmetry to compute the supercurrent in this system for an arbitrary range of parameters (coupling between the impurities, orientation of the impurity spins, etc.). We predict a variety of physical phenomena such as (i) the occurrence of multiple $0-π$ transitions in the regime of weak coupling that can be induced by changing the energy of the YSR states or the temperature; (ii) the critical current strongly depends on the relative orientation of the impurity spins and it is maximized when the spins are either parallel or antiparallel, depending on the ground state of the impurities; and (iii) upon increasing the coupling between impurities, triplet superconductivity is generated in the system and it is manifested in a highly nonsinusoidal current-phase relation. In principle, these predictions can be tested experimentally with the existing realization of this system and the main lessons of this work are of great relevance for the field of superconducting spintronics.

Come as you are : negotiating neoliberal governmentality at a homeless shelter for women and children
Creators: name: Carroll, Aanika Peterson
Publisher: name: University of British Columbia
Year: 2010

description: Non-profit social services targeting specific ‘vulnerable’ groups have become increasingly prevalent since the late 1970s. These services have flourished with the growth of neoliberal ideas that stress rolling back government services, using private institutions that operate on profit-driven models, and creating citizens who are self-sufficient, enterprising subjects. These organizations are an important element of Foucault’s ‘governmentality,’ the idea that independent institutions across society act in concert to regulate the population. This thesis questions the extent to which the goals of neoliberal governmentality are able to penetrate a non-profit organization that provides homeless shelters for women and children in the San Francisco Bay Area, and demonstrates how the organization acts as both a part of the system of neoliberal governmentality while simultaneously resisting its logic. This qualitative research project, which involved participant observation at the shelter site and 16 interviews with staff and clients of the organization, focuses on the ways in which shelter staff have become skilled at responding to the demands of neoliberal governmentality while using unique strategies to address client’s needs and create a home-like shelter environment. The organization employs service strategies that resist the construction of the neoliberal subject as consistently enterprising and rational. Harm-reduction and trauma-informed strategies acknowledge the personal and structural barriers to overcoming problems such as substance abuse and domestic violence, and stress that disciplinary institutional spaces often contribute to the stress and trauma that clients feel within the social services system. Staff members have used these official strategies, as well as their own personal understandings of how they would like the shelter to operate, to develop individual styles and challenge many of the rules within the shelter. This personal and compassionate approach stresses accommodation and is driven by a desire to make the shelter feel more like home.

description: Canada’s minority governments from 2004-2011 were characterized by hyper-partisanship, constant brinkmanship, and a number of constitutional controversies that raised questions about the state of Canadian constitutional conventions. This led a number of academics to call for constitutional reform, particularly to the confidence convention. Those advocating reform sought an alternative to the Canadian negative non-confidence vote, which typically triggers new elections, and embraced more “constructive” non-confidence votes, which limit the possibility of early elections and promote mid-term transitions. The reformers drew on ideas from New Zealand, whose confidence convention encourages constructive non-confidence votes, and from European countries that require all non-confidence votes to simultaneously select an alternative government. This thesis assesses the merits and difficulties of importing such models into Canada and concludes that New Zealand’s confidence protocol is the preferred choice for Canada.

description: Anxiety is a pervasive psychological disorder that exerts a robust influence in the way decisions are made. In spite of the relevance of anxiety in managerial decision making, there is scant literature debating the techniques that anxious managers can apply to attenuate the biases they exhibit. To address this gap, this essay explores the nature of anxiety and the principal violations of normative decision-making found in anxious individuals. After identifying the most suitable techniques to improve decision making in managerial contexts, this essay discusses five techniques that can be easily applied in by anxious managers seeking to improve their decision-making capabilities.

description: The central purpose of this mixed methods study was to explore the effectiveness of two types of training programs (face-to-face and online) that aim to enhance the capacity of service providers to work with street-involved youth (SIY) regarding their sexual and reproductive health (S&RH). Twenty-eight participants completed a six hour face-to-face training program that took place in one day. Twenty-nine participants completed a six hour online training program that took place over two weeks. The study evaluated participants' overall reactions to both training programs as well as three specific outcomes related to capacity development: cognitive learning (knowledge), affective learning (perceived comfort) and use of training (practice behaviour). Knowledge and perceived comfort were measured three times: prior to the training program; immediately after the training program; and six weeks after the training program. Participants’ reactions to the training program were measured immediately after the training program and practice behaviours were measured six weeks after the training program. The outcomes were measured via questionnaires containing closed- and open-ended questions. The quantitative components of this study were analyzed using descriptive statistics, repeated measures ANOVA, independent samples t-tests, and Fisher’s exact tests. The qualitative components were analyzed using content analysis. Overall, the mixed methods data demonstrated that: (a) participants in both training programs had positive reactions to their respective training programs; (b) participants in both programs experienced a statistically significant increase in knowledge immediately after the training and six weeks later; (c) face-to-face participants experienced a statistically significant increase in perceived comfort immediately after the training whereas online participants experienced a statistically significant increase in perceived comfort immediately after the training and six weeks later; and (d) six weeks after the training, approximately 46% of face-to-face participants and 72% of online participants had reportedly used their knowledge from their respective training programs. These findings suggest at least a short term enhancement of capacity development with service providers. Overall, this research demonstrated that although face-to-face and online S&RH training programs have their inherent strengths and challenges, both modalities represent acceptable and effective mechanisms for capacity development of service providers working with SIY.
Improved MPPT Dynamics for Starting and Power Extraction of a Small Wind Turbine Employing a PMSG and a VSMC

description: Small wind turbines usually do not have pitch adjustable blades, hence the aerodynamic starting of a small wind turbine is typically slow due the high angle of attack on the blades. Moreover, most small wind turbines employ a permanent magnet synchronous generator with a cogging torque which has a significant impact on starting. Also, conventional maximum power point tracking (MPPT) takes longer than necessary to return the turbine to its optimal operating condition when the wind speed changes. This dissertation presents a starting strategy that operates the turbine generator as a motor, in order to overcome turbine inertia and the generator cogging torque. When the optimal operating condition is established, operation is switched from motoring to generating. As a result, the turbine can start below the cut-in wind speed, and has a faster starting process as well as an increase in the energy harvested from the wind. Another contribution of this dissertation is short term motoring of the generator during dynamic wind conditions, with the intention that the turbine can more quickly reach the maximum power point operating condition when the wind speed is increasing. To control the motoring and generating operating modes, a bidirectional power flow converter is required. A very sparse matrix converter is a potential candidate, and is employed in a backward configuration where the inverter side of the converter is connected to the generator. Space vector modulation and field oriented control are employed. Experimental verification of the proposed approach involves the use of a 500 W permanent magnet synchronous generator with a very sparse matrix converter in a laboratory set-up. A theoretical extrapolation of the practical results indicate that a 5.7 kW wind turbine can accelerate to the maximum power point in under two seconds for 10~m/s wind speed, and at the same time, increase wind energy harvest compared to the case without the proposed motoring control strategy.

description: Let $G$ be a simply connected, solvable Lie group and $Γ$ a lattice in $G$. The deformation space $\mathcal{D}(Γ,G)$ is the orbit space associated to the action of $\Aut(G)$ on the space $\mathcal{X}(Γ,G)$ of all lattice embeddings of $Γ$ into $G$. Our main result generalises the classical rigidity theorems of Mal'tsev and Saitô for lattices in nilpotent Lie groups and in solvable Lie groups of real type. We prove that the deformation space of every Zariski-dense lattice $Γ$ in $G$ is finite and Hausdorff, provided that the maximal nilpotent normal subgroup of $G$ is connected. This implies that every lattice in a solvable Lie group virtually embeds as a Zariski-dense lattice with finite deformation space. We give examples of solvable Lie groups $G$ which admit Zariski-dense lattices $Γ$ such that $\mathcal{D}(Γ,G)$ is countably infinite, and also examples where the maximal nilpotent normal subgroup of $G$ is connected and simultaneously $G$ has lattices with uncountable deformation space.

description: SF$_6$ is widely used as a gas-insulator in high-voltage power electrical system. Detecting SF$_6$ leaks using unmanned aerial vehicle (UAV)-based thermal cameras allows efficient large-scale inspections during routine maintenance. The emergence of lightweight metalenses can increase the endurance of UAVs. Simultaneously controlling dispersion and polarization properties in metalens is significant for thermal camera applications. However, via a propagation phase modulation method in which the phase is tuned locally, it is difficult and time-consuming to obtain enough different nanostructures to control multiwavelength independently while maintain the polarization-insensitive property. To this end, by using a global modulation method, a polarization-insensitive dual-wavelength achromatic and super-chromatic metalens are designed respectively. The working wavelength is set at 10.6 and 12 $\rmμ$m to match the absorption peaks of SF$_6$ and one of its decompositions (SO$_2$F$_2$), respectively. According to the operating wavelengths, only the geometric parameters of two nanofins are required to be optimized (through genetic algorithm). Then they are superimposed on each other to form cross-shaped meta-atoms. In order to control the influence between the two crossed nanofins, an additional term $Δf$ is introduced into the phase equation to modify the shape of the wavefront, whereby the phase dispersion can be easily engineered. Compared with local modulation, the number of unique nanostructures that need to be optimized can be reduced to two (operating at dual wavelengths) by the Pancharatnam-Berry (PB) phase based global modulation method. Therefore, the proposed design strategy is expected to circumvent difficulties in the local design approaches and can find widespread applications in multiwavelength imaging and spectroscopy.

description: With the advent of WWW and outburst in technology and software development, testing the software became a major concern. Due to the importance of the testing phase in a software development life cycle, testing has been divided into graphical user interface (GUI) based testing, logical testing, integration testing, etc.GUI Testing has become very important as it provides more sophisticated way to interact with the software. The complexity of testing GUI increased over time. The testing needs to be performed in a way that it provides effectiveness, efficiency, increased fault detection rate and good path coverage. To cover all use cases and to provide testing for all possible (success/failure) scenarios the length of the test sequence is considered important. Intent of this paper is to study some techniques used for test case generation and process for various GUI based software applications.

description: The physical interpretation of black hole's quasinormal modes is fundamental for realizing unitary quantum gravity theory as black holes are considered theoretical laboratories for testing models of such an ultimate theory and their quasinormal modes are natural candidates for an interpretation in terms of quantum levels. The spectrum of black hole's quasinormal modes can be re-analysed by introducing a black hole's effective temperature which takes into account the fact that, as shown by Parikh and Wilczek, the radiation spectrum cannot be strictly thermal. This issue changes in a fundamental way the physical understanding of such a spectrum and enables a re-examination of various results in the literature which realizes important modifies on quantum physics of black holes. In particular, the formula of the horizon's area quantization and the number of quanta of area result modified becoming functions of the quantum "overtone" number n. Consequently, the famous formula of Bekenstein-Hawking entropy, its sub-leading corrections and the number of microstates are also modified. Black hole's entropy results a function of the quantum overtone number too. We emphasize that this is the first time that black hole's entropy is directly connected with a quantum number. Previous results in the literature are re-obtained in the limit n \to \infty.

description: Motivated by the advances in deep learning techniques, the application of Unmanned Aerial Vehicle (UAV)-based object detection has proliferated across a range of fields, including vehicle counting, fire detection, and city monitoring. While most existing research studies only a subset of the challenges inherent to UAV-based object detection, there are few studies that balance various aspects to design a practical system for energy consumption reduction. In response, we present the E$^3$-UAV, an edge-based energy-efficient object detection system for UAVs. The system is designed to dynamically support various UAV devices, edge devices, and detection algorithms, with the aim of minimizing energy consumption by deciding the most energy-efficient flight parameters (including flight altitude, flight speed, detection algorithm, and sampling rate) required to fulfill the detection requirements of the task. We first present an effective evaluation metric for actual tasks and construct a transparent energy consumption model based on hundreds of actual flight data to formalize the relationship between energy consumption and flight parameters. Then we present a lightweight energy-efficient priority decision algorithm based on a large quantity of actual flight data to assist the system in deciding flight parameters. Finally, we evaluate the performance of the system, and our experimental results demonstrate that it can significantly decrease energy consumption in real-world scenarios. Additionally, we provide four insights that can assist researchers and engineers in their efforts to study UAV-based object detection further.

description: Chronic myeloid leukemia is a myeloproliferative disorder characterized by the presence of the Philadelphia chromosome, encoding a unique fusion gene BCR-ABL. The current first line treatment for patients diagnosed with CML involves administration of the ABL kinase inhibitor imatinib mesylate (IM). However, early relapses and acquired drug resistance remain a current impediment to successful treatment for many patients. This suggests the necessity for alternate treatment options which may include combination therapy targeting multiple vital proteins involved in the malignancy of the leukemia. AHI-1 (Abelson helper integration site 1) is a recently discovered oncogene that is highly deregulated in murine lymphomas and leukemias. AHI-1 displays a significant pattern of overexpression in a Philadelphia chromosome positive cell line K562 cells. To investigate AHI-1’s involvement in CML, AHI-1 was either stably overexpressed or suppressed in K562 cells. Interestingly, an increase in cellular proliferation and colony formation and a decrease in apoptosis were observed in the presence of IM when AHI-1 was overexpressed, while suppression of AHI-1 had the opposite effects. Phosphorylation and total protein expression levels of several proteins known to be involved in BCR-ABL signalling were quantified. Interestingly, elevated phosphorylation and total gene/protein expression levels of several of these proteins were observed when AHI-1 was overexpresessed, in particular NF-κB and JAK2/STAT5 displayed increased expression. Due to the strong effects AHI-1 had on the JAK2/STAT5 signalling cascade, we then inhibited JAK2 activity using a new JAK2 inhibitor, TG101209. AHI-1 overexpression led to a reduction in the cellular response to the inhibitor while suppression of AHI-1 caused an increase in sensitivity in viability, apoptosis, and colony forming cell assays. Finally, a combination of IM and TG101209 was examined in the same K562 cells lines. Results from suggest that using a combination treatment approach was more effective at inhibiting cellular viability and colony formation than either treatment alone. These findings together suggest that AHI-1 may play an important role in mediating cellular resistance to IM and TG101209 and activates several BCR-ABL signalling pathways, and that it may be a vital target in eradicating the malignant leukemic cells arising in CML.

description: The objective of this study was to determine if all-cause mortality and hospital length of stay among patients who develop ventilator-associated pneumonia (VAP) differs for patients intubated in the Prehospital setting compared to those intubated in the Emergency Department. A retrospective cohort design was employed and secondary data was retrieved from the local VAP Surveillance database and manual chart reviews. Intubated patients entered the cohort upon VAP diagnosis and exited upon death or hospital discharge. This study used data from three large inner-city adult hospitals within Calgary, Alberta Canada. The sample (n=193) consisted of all adult (>18 years old) patients that developed VAP in an Intensive Care Unit who were intubated either in the Prehospital or Emergency Department setting during the study period (January 01, 2005 and December 31, 2009). Patients in this study intubated in the Prehospital setting were very similar to patients intubated in the Emergency Department with regards to basic demographic and admission characteristics. This study provides several novel results about the association between endotracheal intubation (ETI) location and morbidity and mortality among patients who acquire VAP in the ICU. Patients who suffer severe illness or injury (APACHE II score >25) are more likely to die if they are intubated in the Prehospital setting compared to the Emergency Department (p=<0.001). Furthermore, Prehospital ETI patients who die, do so sooner than Emergency Department ETI patients; whereas Prehospital ETI patients who survive, have longer hospitalizations than their Emergency Department counterparts (p=<0.001). Perhaps preventing ETI in the Prehospital setting or postponing ETI until Emergency Department would result in decreased hospital mortality. Further research is required before this information should be used in a clinical setting.

description: Staphylococcus aureus infections have spread globally and caused significant morbidity and mortality. Previous studies have indicated several functions that Staphylococcal Protein A (SPA) plays to enhance S. aureus virulence. To evaluate the role of SPA in S. aureus with respect to virulence and other biological functions, the chimeric clones were constructed by replacing the spa gene of a high-virulence S. aureus strain with the spa from a non/low-virulence strain, and vice versa. Three representative MRSA strains, a high-virulence CA-MRSA strain USA300 (spa t008), a typically low-virulence hospital-associated MRSA strain CMRSA6 (spa t037) and an avirulent colonization strain M92 (non-typeable spa) with different genetic backgrounds (ST8, ST239 and ST239, respectively) were selected. Expression of the spa gene was confirmed by western blot. The chimeric clone was evaluated by its growth curve, immunoglobulin (IgG) binding capacity, biofilm formation, and virulence using the Caenorhabditis elegans nematode infection model, and compared with the wild type (WT) donor strains. The chimeric clone USA300spa▲:: CMRSA6 spa, which had the background of a high virulence strain USA300 with the native spa gene being replaced by the spa gene of a low virulence strain CMRSA6, showed a slower growth rate, and a significantly decreased SPA expression with a 24-fold dramatic reduction in SPA IgG-Fc binding capacity. There was a 3.4-fold increase in the biofilm formation and a 62% reduction in the nematocidal activity, when compared to the parent strain WT-USA300. The other two opposite chimeric clones (M92 spa▲::USA300 spa and M92spa▲::CMRSA6spa) were constructed from an avirulent colonization strain M92, with the native spa gene being replaced with the spa genes of a high virulence strain USA300 and a low virulence strain CMRSA6, respectively. Both chimeric clones (M92 spa▲::USA300 spa and M92spa▲::CMRSA6spa) showed slight changes in growth rates, significantly increased SPA expression with 1.6- and 0.7-fold increase in SPA IgG-Fc binding capacity, respectively. No significant change was observed in the biofilm formation and the nematocidal activity of both chimeric clones when compared to the parent strain WT-M92. In conclusion, replacing the spa gene of S. aureus strain altered its biological characteristics, behavior and virulence. This study resultssuggests that spa plays an important role in the virulence and pathogenicity of S. aureus infections.

description: Anomaly detection (AD) in images, identifying significant deviations from normality, is a critical issue in computer vision. This paper introduces a novel approach to dimensionality reduction for AD using pre-trained convolutional neural network (CNN) that incorporate EfficientNet models. We investigate the importance of component selection and propose two types of tree search approaches, both employing a greedy strategy, for optimal eigencomponent selection. Our study conducts three main experiments to evaluate the effectiveness of our approach. The first experiment explores the influence of test set performance on component choice, the second experiment examines the performance when we train on one anomaly type and evaluate on all other types, and the third experiment investigates the impact of using a minimum number of images for training and selecting them based on anomaly types. Our approach aims to find the optimal subset of components that deliver the highest performance score, instead of focusing solely on the proportion of variance explained by each component and also understand the components behaviour in different settings. Our results indicate that the proposed method surpasses both Principal Component Analysis (PCA) and Negated Principal Component Analysis (NPCA) in terms of detection accuracy, even when using fewer components. Thus, our approach provides a promising alternative to conventional dimensionality reduction techniques in AD, and holds potential to enhance the efficiency and effectiveness of AD systems.

description: We introduce event identifier logic (EIL) which extends Hennessy-Milner logic by the addition of (1) reverse as well as forward modalities, and (2) identifiers to keep track of events. We show that this logic corresponds to hereditary history-preserving (HH) bisimulation equivalence within a particular true-concurrency model, namely stable configuration structures. We furthermore show how natural sublogics of EIL correspond to coarser equivalences. In particular we provide logical characterisations of weak history-preserving (WH) and history-preserving (H) bisimulation. Logics corresponding to HH and H bisimulation have been given previously, but not to WH bisimulation (when autoconcurrency is allowed), as far as we are aware. We also present characteristic formulas which characterise individual structures with respect to history-preserving equivalences.

description: The goal of this thesis is to explore the perceptions and experiences of both staff and volunteers in the Kananaskis region. Conservation volunteerism is a practice that is important to society and often an Essential component to environmental organizations, inclusive of government parks departments. An empirical study was conducted using applied thematic analysis to examine quantitative and qualitative survey data collected from staff and volunteers in the Kananaskis region of Alberta. An emphasis was placed on comparing responses of staff and volunteers in terms of their motivations and values. The study found that although volunteers and staff both believe Alberta Parks has volunteers predominantly because of resource shortages, volunteers seem to appreciate the personal relationships they develop with local staff more than Alberta Parks may recognize. Patterns that emerge in this study have the potential to influence the future of volunteer practices in conservation volunteerism.
