description: The need to explore the lived experiences of a Home Share family stems from a number of factors. Few housing options exist for youth and adults with an intellectual disability (ID) or a developmental disability (DD) who want to live in community, and thus individuals end up in Home Share settings (Hughson, 2013). Statistics gathered in British Columbia illustrate that the number of people living with intellectual and developmental disabilities are on waiting lists for housing placement for years. Additionally, there is little literature on the deep culture and informal renderings of the phenomenon of ‘home’ in the Home Share family. Finally, the parents of loved ones transitioning into community living are fearful of what they do not know; ‘what is the Home Share family all about’? And, ‘how will it serve my adult child’? The inquiry was framed within a hermeneutic phenomenological approach. The Photo-voice method for gathering data was utilized by four family members: two Home Share providers and two adults living with ID/DD. Photo images combined with participants’ associations, anecdotes and stories provide the data of their lived experiences. Van Manen’s (2014b) vocative method of analysis enabled the lived experiences to become more vivid and present; where insights into the phenomenon of home showed themselves. The research findings are descriptive in nature and include psycho-social aspects within the family dynamic that contribute to a good quality of life for people with ID/DD; attributes and features that make a family home the best it can be in a Home Share setting; and lessons learned from a rich exploration of one Home Share family.

description: In a recent publication (S. Dong et al., Phys. Rev. Lett.103, 127201 (2009)), two (related) mechanisms were proposed to understand the intrinsic exchange bias present in oxides heterostructures involving G-type antiferromagnetic perovskites. The first mechanism is driven by the Dzyaloshinskii-Moriya interaction, which is a spin-orbit coupling effect. The second is induced by the ferroelectric polarization, and it is only active in heterostructures involving multiferroics. Using the SrRuO$_3$/SrMnO$_3$ superlattice as a model system, density-functional calculations are here performed to verify the two proposals. This proof-of-principle calculation provides convincing evidence that qualitatively supports both proposals.

description: Production from oil and shale gas-condensate reservoirs in the United States and Canada has increased during the past few years. However, an understanding of shale rocks and fluid flow through them is still limited. Thus, the objective of this research is to develop methodologies for characterizing multi-porosities in shale petroleum reservoirs and for simulating fluid flow of oil and condensates through these types of rocks. The characterization part is carried out with the use of (1) an original petrophysical model built for quantification of total organic carbon (TOC), Knudsen number, water saturation, and multiple porosities in shales, (2) measurement of gas permeability from shale samples in the laboratory using commercial equipment, and (3) an original laboratory-based correlation for estimating stress-dependent permeability, porosity and compressibility of tight rocks. The simulation part is carried out with the use of (1) an original radial numerical model developed for calculating sorption-dependent permeability of shales, (2) a commercial 3D model for investigating pore size-dependency of pressure-temperature envelopes in shale gas-condensate reservoirs, and (3) an original fully-implicit 3D-3phase pseudo-compositional model for oil and condensate shale reservoirs developed with capabilities to handle multiple porosities and stress-dependent properties of natural and hydraulic fractures. Key challenges include the handling of (1) adsorbed porosity, (2) organic porosity, (3) inorganic porosity, (4) natural fracture porosity, (5) hydraulic fracture porosity, (6) diffusion from solid kerogen, and (7) fluid transport in the small pores of shales, which deviate significantly from the behavior in conventional reservoirs. It is concluded that the methods developed in this thesis provide important foundation for the characterization and simulation of shale petroleum reservoirs.

description: The pressure-driven growth model that describes the two-dimensional (2-D) propagation of a foam through an oil reservoir is considered as a model for surfactant-alternating-gas improved oil recovery. The model assumes a region of low mobility, finely textured foam at the foam front where injected gas meets liquid. The net pressure driving the foam is assumed to reduce suddenly at a specific time. Parts of the foam front, deep down near the bottom of the front, must then backtrack, reversing their flow direction. Equations for one-dimensional fractional flow, underlying 2-D pressure-driven growth, are solved via the method of characteristics. In a diagram of position versus time, the backtracking front has a complex double fan structure, with two distinct characteristic fans interacting. One of these characteristic fans is a reflection of a fan already present in forward flow mode. The second fan however only appears upon flow reversal. Both fans contribute to the flow's Darcy pressure drop, the balance of the pressure drop shifting over time from the first fan to the second. The implications for 2-D pressure-driven growth are that the foam front has even lower mobility in reverse flow mode than it had in the original forward flow case.
Investigation of Robust Chatter Stability in Milling

Subjects: subject: Engineering--Mechanical
subject: Chatter

subject: Edge Theorem
subject: Linear matrix inequality

description: In machining operations, self-excited regenerative chatter can develop due to a phase difference between overlapping cutting paths which results in oscillating chip thickness. Machine tool chatter decreases overall productivity and quality of manufactured parts due to excessive vibrations. Analytical models are used to predict the chatter stability lobe diagrams, which illustrate stable and unstable combinations of cutting depths and spindle speeds. The conventional chatter models, however, typically assume that parameters are constant, which leads to inaccuracy. Dynamics, including natural frequencies, damping ratios, and cutting coefficients are the primary parameters that are susceptible to uncertainty and can vary during real milling operations. Especially in micro milling, high spindle speeds can generate centrifugal forces, gyroscopic moments, and thermal effects in the spindle bearings, which can significantly affect tooltip dynamics. Cutting coefficients reflect how the cutting tool interacts with the workpiece material and due to the miniature tool size, material uniformity, tool geometry, and frictional effects, can all affect cutting coefficient values. In addition, cutting coefficients can also be affected by the two different cutting regimes, ploughing or shearing dominant that can exist depending upon the chip thickness with respect to the edge radius of tools. The effects of parameter uncertainty can be directly taken into consideration using the robust stability approaches. The objective of this study is to develop two robust formulations for predicting regenerative chatter stability in micro milling while considering the effects of three uncertain parameters: namely natural frequencies, damping ratios, and cutting coefficients. A frequency domain approach using the Edge theorem can analytically account for time invariant parameter uncertainty directly in the characteristic equation. Combined with the Zero Exclusion principle, computation of stability regions can be efficiently checked graphically. Robust chatter stability can also be detected using Lyapunov stability subjected to linear matrix inequality (LMI) constraints. Experiments are conducted to demonstrate that, while both methods can conservatively predict system stability, the Edge theorem approach predicts the stability lobes faster. From an accuracy and computational time viewpoint, both robust stability approaches are compared for establishing micro milling chatter stability regions. Whereas the LMI approach can be extended to account for time varying parameter uncertainty.

description: The upper critical fields, $H_{c2}$($T$), of single crystals of the superconductor Ca$_{10}$(Pt$_{4-δ}$As$_{8}$)((Fe$_{0.97}$Pt$_{0.03}$)$_{2}$As$_{2}$)$_{5}$ ($δ$ $\approx$ 0.246) are determined over a wide range of temperatures down to $T$ = 1.42 K and magnetic fields of up to $μ_{0}H$ $\simeq$ 92 T. The measurements of anisotropic $H_{c2}$($T$) curves are performed in pulsed magnetic fields using radio-frequency contactless penetration depth measurements for magnetic field applied both parallel and perpendicular to the \textbf{ab}-plane. Whereas a clear upward curvature in $H_{c2}^{\parallel\textbf{c}}$($T$) along \textbf{H}$\parallel$\textbf{c} is observed with decreasing temperature, the $H_{c2}^{\parallel\textbf{ab}}$($T$) along \textbf{H}$\parallel$\textbf{ab} shows a flattening at low temperatures. The rapid increase of the $H_{c2}^{\parallel\textbf{c}}$($T$) at low temperatures suggests that the superconductivity can be described by two dominating bands. The anisotropy parameter, $γ_{H}$ $\equiv$ $H_{c2}^{\parallel\textbf{ab}}/H_{c2}^{\parallel\textbf{c}}$, is $\sim$7 close to $T_{c}$ and decreases considerably to $\sim$1 with decreasing temperature, showing rather weak anisotropy at low temperatures.

description: Monte Carlo simulation is used to investigate the fluctuations in the Xe proportional electroluminescence (EL) yield H (also known as secondary scintillation) produced by sub-ionization primary electrons drifting in the gas under appropriate electric fields, comparing pure Xe gas with Xe doped with CH4 or CF4. The work is modeled on gas detectors of the gas proportional-scintillation type, where amplification is achieved through the production of EL under a charge-multiplication free regime. The addition of the molecular gases to Xe reduces electron diffusion, a desirable effect in large size detectors where primary electrons drift across a long absorption/drift region. However, the presence of the molecules reduces H and increases its fluctuations. In the case of CF4, the effects are very strong due to significant electron attachment in the EL field range, ruling out CF4 as an acceptable additive. The addition of CH4 affects H and its fluctuations to a much lower extent, and CH4 concentrations lower than ~1% may be an appropriate choice. In addition, Monte Carlo calculations in pure Xe under cylindrical geometry in a regime below charge multiplication have shown that fluctuations in the EL yield H are an order of magnitude higher than for planar geometry. For both geometries, though, the fluctuations have a negligible effect on the energy resolution, and variations of the anode radius in cylindrical geometry or grid parallelism in planar geometry may be a more significant cause of concern.

description: In this project a geophysical survey was conducted on the rock glacier in the Helen Lake watershed (Ban National Park, Alberta, Canada) to investigate its internal structure. Geophysical methods involved electrical resistivity tomography, seismic refraction and ground penetrating radar. The main objectives were (1) to identify the presence of ice, (2) determine the depth to bedrock and (3) trace the pathways of ground water flow. The conceptual model of the rock glacier was built based on the interpretation of geophysical data sets. It showed that the rock glacier represents an important hydrological unit playing a significant role in storage and release of water sustaining the late summer flow in the watershed. This research contributes to the understanding of how such hydrological units as rock glaciers function and what predictions could be made about the consequences of the climate warming for these natural water reservoirs.

description: All organizations are subject to uncertainty and risk, the nature and extent of which ultimately affect their performance and may even threaten their survival. The frequency and severity of risk events and perceived failures of risk management and risk oversight in organizational contexts have shaken confidence in prevailing practices and stimulated reforms. As a result, many top management teams (TMTs) and boards of directors (boards) are increasingly adopting and adapting new risk governance practices. These practices comprise ideas such as enterprise risk management (ERM); structures such as risk committees, risk functions, and chief risk officers (CROs); processes such as risk aggregation and risk integration; and techniques such as risk appetite. Although some patterns of adoption, adaptation, and diffusion have emerged, our understanding of the underlying mechanisms is limited and underexplored. Despite decades of scholarly inquiry into risk behaviour in organizational contexts, the dominant theoretical perspectives remain undercontextualized and the empirical findings remain equivocal. In this multi-paper thesis, I explore the current state of knowledge regarding organizational risk and risk governance innovations and propose directions for future research. In the first paper, I build process theory from multiple cases to address why and how social actors in organizational contexts construct risk governance. In the second paper, I evaluate aggregated empirical results through a meta-analytic procedure to address why social actors in organizational contexts engage in risk behaviour. In the third paper, I elaborate process theory from multiple cases to address how social actors in organizational contexts could construct risk preference. Findings from this research reconfirm the need for scholars to extend their theoretical and empirical inquiry into organizational risk and risk governance innovations beyond the dominant technico-scientific and modernist perspectives and embrace the emergent socio-cultural and postmodernist perspectives.

description: Sensitive and high angular resolution ($\sim$ $0\rlap.{"}7$) (sub)millimeter line and continuum observations of the massive star forming region W3(OH) made with the Submillimeter Array are presented. We report the first detection of two bipolar outflows emanating from the young and massive "Turner-Welch" [TW] protobinary system detected by the emission of the carbon monoxide. The outflows are massive (10 M$_\odot$), highly-collimated (10$^\circ$), and seem to be the extended molecular component of the strong radio jets and a 22 GHz maser water outflow energized also by the stars in the W3(OH)TW system. Observations of the 890 $μ$m continuum emission and the thermal emission of the CH$_3$OH might suggest the presence of two rotating circumstellar disk-like structures associated with the binary system. The disks-like structures have sizes of about 1500 AU, masses of a few M$_\odot$ and appear to energize the molecular outflows and radio jets. We estimate that the young stars feeding the outflows and that are surrounded by the massive disk-like structures maybe are B-type.

To determine the gradient of solution on the boundary, we need to solve the boundary integral equation numerically in most practical cases. Here we discuss the alternative method to avert solving that boundary integral equation. It is based on the solution for Poisson's equation which has the singularity on the boundary specified by the boundary function and shown it is applicable to arbitrary shaped domain and reduces calculation cost considerably.

description: In my dissertation Creativity, Culture, and Genius: Nietzsche's Ethics of the Creative Life I aim to articulate what creativity means to Nietzsche. I present an account of Nietzsche in which creativity exemplifies the "highest potential power and splendour" (GM P: 6) of human beings. Specifically, I hope to demonstrate that what is best about us is creativity, and that to live a creative life is to have creativity as a governing principle. Although Nietzsche does not explicitly state that people should have creativity as a governing principle for organizing lives, I will show that this thought lies within his work implicitly. To do this, I use Aristotle as a foil for Nietzsche and contrast their thinking on the question, "What characteristic exemplifies what is best about humans?" Aristotle believed that there were three potential answers to this question: pleasure, noble action and politics, and contemplation. I put Nietzsche to work philosophically, contrasting these three possible answers with Nietzsche's philosophy, and showing that none of them are viable options. The positive portion of my project focuses on demonstrating the interconnectedness of creativity, culture, and genius for Nietzsche. The importance of these three concepts cannot be underestimated in Nietzsche's philosophy, and I show how they are vital to his thought – with creativity serving as the central focus and a governing principle for human beings.

We derive effective intra- and interlayer dipole-dipole interaction potentials and provide simple analytical approximations for a given number of lattice sites at arbitrary polarization. We find that the interlayer dipole-dipole interaction changes the transverse aspect ratio of the ground state in the central layers depending on its polarization and the number of lattice sites. The changing aspect ratio should be observable in time of flight images. Furthermore, we show that the interlayer dipole-dipole interaction reduces the excitation energy of local perturbations, affecting the development of a roton minimum.

description: Human aortic endothelial cells (HAECs) have been observed to respond to fluid flow and shear stress by activating different signalling molecules both in vitro and in vivo. An important example of these flow-activated molecules is Smad2. Smad2 is a signalling molecule and transcription factor that has shown to be indispensable for the maintenance of vascular integrity. The aim of this study was to understand the effect of shear stress and Smad2 knockdown on endothelial gene expression. HAEC were transfected with Smad2 siRNA, and exposed to steady laminar shear stress (10 dyne/cm2). Our results showed that Smad2 siRNA and shear stress significantly up-regulated genes involved in atherosclerosis, heart dysfunction, and angiogenesis. Furthermore, Smad2 siRNA had a negative impact on athero-protective genes under static conditions. This is the first reported Smad2 siRNA gene expression profile of endothelial cells. Our findings suggest that Smad2 may a have a protective role against cardiovascular diseases.
Quality of Experience and Mobility-Aware Green Inter-Radio Access Technology Traffic Offloading

description: Traffic offloading among coexisting heterogeneous radio access technologies (RATs) (i.e., inter-RAT offloading) is considered an effective strategy for enhancing the capacity of wireless networks and reducing the power consumption of base stations (BSs) and mobile stations (MSs). To fully utilize inter-RAT offloading advantages, a mobility-aware evaluation is needed, which takes into account the combined effects of mobility and MSs/BSs spatial distributions on the performance gains. This thesis develops an analytical mobility-aware evaluation framework that accurately evaluates the performance of inter-RAT offloading while accounting for the MSs/BSs spatial distribution. This framework is then utilized to develop a novel mobility-aware inter-RAT offloading policy, which aims at associating a MS to the best RAT at any time that optimizes a predefined multi-criterion objective. Deploying a power saving mode (PSM) is also considered an effective solution for saving energy. To efficiently exploit the PSM power saving capabilities for voice over IP (VoIP) services, a quality of experience (QoE)-aware PSM performance evaluation is needed. This thesis develops an analytical evaluation framework that assesses the QoE and energy consumption achieved by a fixed PSM. Based on this framework, this thesis develops a novel QoE-aware PSM, which exploits the on-off characteristics of VoIP sessions to further improve the energy saving while accounting for the bursty losses effects on the QoE. Finally, benefits of deploying a PSM can be combined with those of utilizing inter-RAT offloading to maximize the energy saving while guaranteeing a desired level of QoE for VoIP services. This thesis develops an analytical inter-RAT offloading performance evaluation framework that assesses the QoE and energy consumption achieved by an inter-RAT traffic offloading policy taking into account the PSM being used. Based on this framework, this thesis develops a novel QoE/mobility-aware inter-RAT offloading policy that jointly utilizes the inter-RAT offloading and PSM for optimizing a predefined multi-criterion objective. The research in this thesis offers potentials for enhancing performance while reducing computational complexity. The numerical results validate the accuracy of the proposed performance evaluation frameworks and verify the efficacy of the proposed techniques in enhancing the performance compared to their counterparts.

description: We describe a technique for constructing a symplectic transfer map for a charged particle moving through an accelerator component with arbitrary three-dimensional static magnetic field. The transfer map is constructed by symplectic integration; by representing the map at each step of the integration by a mixed-variable generating function, exact symplecticity is ensured. By using an appropriate integration algorithm, there is no necessity to make the paraxial approximation. The technique is illustrated by application (in one degree of freedom) to a quadrupole magnet with strong octupole component and fringe field.

Barriers to immigrants seeking housing in a mid-sized city : a case study of visible minorities in Kelowna's housing market
Creators: name: Oh, John Doo Jin
Publisher: name: University of British Columbia
Year: 2010

description: In trying to settle in Canadian cities, one of the many challenges faced by immigrants—particularly visible minorities—is difficulty finding housing. This may be especially true in mid-sized cities where little is known about the settlement experience of immigrants. The purpose of this study is to examine the housing experiences of visible minority immigrants in the mid-sized city of Kelowna, British Columbia. In particular, it focuses on the challenges and barriers visible minority immigrants face in one of Canada’s most expensive housing markets. The role of race as a factor in the housing experience of these immigrants is also examined. The study also looks at strategies immigrants use to cope with housing barriers and makes recommendations on how their housing situation can be improved. Data for this study was obtained from a questionnaire survey administered to 30 visible minority immigrants in the city of Kelowna. The questionnaire survey focused on the respondents’ housing experiences and on the challenges, such as discrimination, that they faced. In addition to the survey, supplementary data was obtained from semi-structured interviews with 10 key informants in Kelowna. Results from the study indicate that visible minority immigrants in the mid-sized city of Kelowna are experiencing severe difficulties in their housing searches and, ultimately, in their settlement process. The main housing barriers and challenges uncovered by this study were affordability, discrimination, and a lack of service support from social networks or community organizations. These factors often resulted in the respondents’ housing search process and their attainment of adequate housing being hindered or prevented. This study expands on the existing literature by emphasizing the importance of race in the housing experience of visible minority immigrants in a mid-sized city. In concurrence with other major Canadian studies, this study reiterates the notion that immigrants, especially visible minorities, are experiencing various challenges and barriers in the housing search process. Recommendations from this study conclude that there is a need for more social support in the form of affordable housing, and immigrant settlement services, and the need for a more welcoming community to help alleviate these barriers.

description: The RAdial Velocity Experiment (RAVE) is a medium resolution R~7500 spectroscopic survey of the Milky Way which already obtained over half a million stellar spectra. They present a randomly selected magnitude-limited sample, so it is important to use a reliable and automated classification scheme which identifies normal single stars and discovers different types of peculiar stars. To this end we present a morphological classification of 350,000 RAVE survey stellar spectra using locally linear embedding, a dimensionality reduction method which enables representing the complex spectral morphology in a low dimensional projected space while still preserving the properties of the local neighborhoods of spectra. We find that the majority of all spectra in the database ~90-95% belong to normal single stars, but there is also a significant population of several types of peculiars. Among them the most populated groups are those of various types of spectroscopic binary and chromospherically active stars. Both of them include several thousands of spectra. Particularly the latter group offers significant further investigation opportunities since activity of stars is a known proxy of stellar ages. Applying the same classification procedure to the sample of normal single stars alone shows that the shape of the projected manifold in two dimensional space correlates with stellar temperature, surface gravity and metallicity.

description: The singlet dynamics which plays a major role in the physics of the spin-1/2 Quantum Heisenberg Antiferromagnet (QHAF) on the Kagome lattice can be approximately described by projecting onto the nearest-neighbor valence bond (NNVB) singlet subspace. We re-visit here the effective Quantum Dimer Model which originates from the latter NNVB-projected Heisenberg model via a non-perturbative Rokhsar-Kivelson-like scheme. By using Lanczos exact diagonalisation on a 108-site cluster supplemented by a careful symmetry analysis, it is shown that a previously-found 36-site Valence Bond Crystal (VBC) in fact competes with a new type of 12-site "{\it resonating-columnar}" VBC. The exceptionally large degeneracy of the GS multiplets (144 on our 108-site cluster) might reflect the proximity of the Z_2 dimer liquid. Interestingly, these two VBC "emerge" in {\it different topological sectors}. Implications for the interpretation of numerical results on the QHAF are outlined.

description: Architecture has long relied on optical devices to recalibrate vision towards previously concealed datasets. This thesis situates Algorithmic Observation (AO) as a tool within this lineage and explores its ability to invert architectures’ relationship to optical prostheses through the production of n-dimensional vectors. AO is tasked with sensing and making sense of the physical city, a process that relies on the production of algorithmically curated images. These images multiply and reanimate the image of the city provoking new optical regimes that situate aesthetics at the forefront of how architecture is conceived and constructed. This thesis explores a framework for extracting and mobilizing n-dimensional vectors towards the production of an architecture concerned not only with its physical materiality but with its digital footprint.

description: Neurological decline associated with non-pathological aging is fast becoming a primary concern of Western societies as we are beginning to feel the social, monetary and emotional pressures of an aging population. It is evident that the aging nervous system, whether invertebrate or vertebrate, suffers from a progressive deterioration of plastic components, most noticeably that of learning and memory. While this process likely has a diverse and multifactorial cellular and molecular foundation, one of the foremost mechanistic explanations is captured within the Free Radical Theory of Aging. The theory postulates that senescence is the result of progressive pro-oxidative shifts in cellular redox states and consequential oxidation-dependent alterations in cell physiology. While we are beginning to quantify these changes, it is often difficult to distinguish the adaptive from the maladaptive when considering how molecular changes within the neuron correspond to whole animal neuronal functionality. Using an invertebrate model with a rich history in neurobiology and aging research, the following thesis attempts to bridge this gap in our understanding by investigating the relationship between age-related changes in metabolism, cellular oxidation states, neuronal (electro) physiology and whole animal cognitive performance. My findings implicate age-related changes in metabolism and concurrent glutathione-dependent pro-oxidative shifts in cellular redox states, to be a foundational mechanism behind age-dependent neuronal hypoexcitability and the concurrent behavioural manifestation of long term memory impairment. Moreover, this work pinpoints oxidation-dependent provocation of phospholipase A2, and the resultant release of free fatty acids, to be the molecular fulcrum through which changing cellular oxidation states are translated into electrophysiological and behavioural consequences for the animal. These findings build on a growing body of evidence describing a central role for oxidative stress and perturbed lipid metabolism in neuronal excitability control and age-associated perturbations in cognitive performance. Taken together, the fundamental molecular processes described within this thesis support the optimistic view that the mechanisms of non-pathological aging may suspend rather than irreversibly extinguish the aging brain’s plastic capacity.

description: Currently there is limited research on the impact of adiposity and physical activity on influenza vaccination. The purpose of this pilot study was to investigate the role of adiposity and physical activity in the immune response of males aged 18-35 to the 2014/2015 seasonal trivalent influenza vaccine. Blood was drawn pre and four weeks post vaccination. Serum samples were analyzed for changes in antibody titers, serum leptin, soluble leptin receptors (sLEPR) and C-reactive protein (CRP). No differences in median percent body fat, leptin, sLEPR or CRP were associated with seroconversion rates. Participants with higher physical activity scores had lower seroconversion rates. Differences were found for the A/Texas strain (p<0.01) with a similar trend observed for the other influenza strains. Further work needs to be done in this area to confirm this trend.

description: The relationship between economic change and mental health in resource-based communities has been largely unexplored. This historical case study examines how mental health was understood alongside changing economic circumstances in the resource-based community of Kitimat, British Columbia. A content analysis of archival documents and eight qualitative interviews with long-term residents revealed that understandings of mental health shifted according to local economic circumstances. Specifically, during times of economic growth the socially ideal family unit was seen as a way to achieve mental health. Conversely, during times of economic downturn residents were preoccupied with issues like housing or unemployment, which they identified as essential to their mental health. Overall, residents’ understandings of mental health aligned with holistic or biomedical perspectives, and sometimes both. Considering the recent state of economic development in Kitimat, and its inevitable downturn—common to other resource-based communities—this study offers important insight into the implications for mental health.
