Songbird incubation dilemmas in the alpine: managing parent-offspring trade-offs in a variable thermal environment
Creators: name: MacDonald, Elizabeth Catherine
Publisher: name: University of British Columbia
Year: 2012

description: Small-bodied bird species exhibiting single-sex incubation must expend energy to create a buffered thermal environment for their eggs, while also meeting their own energetic requirements. The resultant trade-off between incubation and foraging is intensified in cold environments like the alpine, where energetic constraints are high. Ambient temperature influences incubation behaviour, with variable relationships across species, habitats and populations. I examined incubation rhythms of an alpine population of Horned Larks (Eremophila alpestris) in British Columbia across four years with different thermal regimes (2005 = moderate, 2006 = warm, 2010 = cold overnight, 2011 = cold during day) to determine whether incubating larks exhibited variable relationships between attentivity and temperature under different thermal conditions and how this related to management of the parent-offspring trade-off. Early in the morning, females had to leave their nest to forage to reduce their energy deficit following 7 h of night incubation in near freezing conditions. Since temperatures at this time were still < 5˚C, embryos were at a high risk of potentially lethal chilling when females left the nest. From 06:00 to 08:00, incubating larks reduced attentiveness to 75% from 94% overnight. However, during this time period, females in 2010 spent more time off the nest as temperatures warmed than in other years. Throughout the study, adults took occasional “extended recesses” (incubation breaks lasting ≥ 59 min). These recesses were longer and more frequent in cold years, particularly 2011, and appeared to be largely related to harsh weather events. There are potential fitness consequences associated with these extended recesses, as egg hatching rate dropped to 81% in 2011 from 94% in the other years, and the incubation period was lengthened in two nests that engaged in multiple extended recesses. Overall, this work demonstrated that incubating larks favour themselves when coping with difficult thermal conditions. Lark embryos appeared more tolerant to long periods of considerable cooling than previously thought, although, the reduced hatching rate in one cold year suggested there may be a limit to their cold tolerance.

description: Consider a one-way analysis of covariance model. Suppose that the parameter of interest theta is a specified linear contrast of the expected responses, for a given value of the covariate. Also suppose that the inference of interest is a 1-alpha confidence interval for theta. The following two-stage procedure has been proposed to determine the form of the model. In Stage 1, we carry out an F test of the null hypothesis that the slopes are all zero against the alternative hypothesis that they are not all zero. If this null hypothesis is accepted then we assume that the slopes are all zero; otherwise we proceed to Stage 2. In Stage 2, we carry out an F test of the null hypothesis that the slopes are all equal against the alternative hypothesis that they are not all equal. If this null hypothesis is accepted then we assume that the slopes are all equal; otherwise this assumption is not made. We present a general methodology for the examination of the effect of this two-stage model selection procedure on the coverage probability of a subsequently-constructed confidence interval for theta, with nominal coverage 1-alpha. This methodology is applied to a numerical example for which it is shown that this confidence interval is completely inadequate.

The Neuronal Architecture of Autonomic Dysreflexia
Creators: name: Soriano, Jan Elaine
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Neuroscience

description: Autonomic dysreflexia is a life-threatening medical condition characterized by episodes of uncontrolled hypertension that occur in response to sensory stimuli after spinal cord injury (SCI). The fragmented understanding of the mechanisms underlying autonomic dysreflexia hampers the development of therapeutic strategies to manage this condition, leaving people with SCI at daily risk of heart attack and stroke. Here, we expose the complete de novo neuronal architecture that develops after SCI and causes autonomic dysreflexia. In parallel, we uncover a competing, yet overlapping neuronal architecture activated by epidural electrical stimulation of the spinal cord that safely regulates blood pressure after SCI. The discovery that these adversarial neuronal architectures converge onto a single neuronal subpopulation provided a blueprint for the design of a mechanism-based intervention that reversed autonomic dysreflexia in mice, rats, and humans with SCI. These results establish a path for the effective treatment of autonomic dysreflexia in people with SCI.

One-channel conductor coupled to a quantum of resistance: exact ac conductance and finite-frequency noise

description: We consider a one-channel coherent conductor with a good transmission embedded into an ohmic environment whose impedance is equal to the quantum of resistance R_q=h/e^2 below the RC frequency. This choice is motivated by the mapping of this problem to a Tomonaga-Luttinger liquid with one impurity whose interaction parameter corresponds to the specific value K=1/2, allowing for a refermionization procedure. The "new" fermions have an energy-dependent transmission amplitude which incorporates the strong correlation effects and yields the exact dc current and zero-frequency noise through expressions similar to those of the scattering approach. We recall and discuss these results for our present purpose. Then we compute, for the first time, the finite-frequency differential conductance and the finite-frequency non-symmetrized noise. Contrary to intuitive expectation, both cannot be expressed within the scattering approach for the new fermions, even though they are still determined by the transmission amplitude. Even more, the finite-frequency conductance obeys an exact relation in terms of the dc current which is similar to that derived perturbatively with respect to weak tunneling within the Tien-Gordon theory, and extended recently to arbitrary strongly interacting systems coupled eventually to an environment or/and with a fractional charge. We also show that the emission excess noise vanishes exactly above eV, even though the underlying Tomonaga-Luttinger liquid model corresponds to a many-body correlated system. Our results apply for all ranges of temperature, voltages and frequencies below the RC frequency, and they allow to explore fully the quantum regime.

description: Oggetto del presente studio è il gruppo di terracotte figurate di epoca ellenistica e, solo in un caso, tardo-classica, appartenenti alla Collezione Archeologica “Francesco Messina”. Il materiale rappresenta un nucleo piuttosto omogeneo e il più cospicuo fra quelli individuabili nella raccolta. Le terracotte sono prive di dati di provenienza e/o acquisizione e per questo motivo la datazione dei singoli pezzi è basata solo su confronti e dati stilistici, indicati volta per volta nelle schede tecniche dei materiali. I pezzi presi in esame sono 23 (principalmente figure femminili, un esiguo nucleo di figure maschili e alcune figure riferibili all'universo dionisiaco). Ad un’introduzione generale sul valore e le funzioni della coroplastica segue il catalogo dei fittili, presentati per gruppi tipologici: alle schede dei materiali di ogni gruppo si è fatta precedere una breve introduzione che consenta di inquadrare in maniera generale la singola tipologia.

This paper represents the last step of the study of a group of Hellenistic and, in one case, late classical terracottas from the Francesco Messina’s Archaeological Collection. The terracottas represents a rather homogeneous group and the most conspicuous among the ones that form the collection. The terracottas lack of any kind of information about their origins and this is why the dating and interpretation of every piece is based exclusively on the comparison with other materials and on stylistic analysis (of which the author provides explanation and justification in the technical records). The group is formed by 23 terracottas (mainly female figures of humans and deities, a small number of male figures and some figures related to Dionysiac universe). After the general introduction about the role and functions of coroplastic production follows the catalogue of terracottas which are presented by typological order. The records are preceded by a small introduction that aims to better contextualize all the types of terracottas here presented.

The minimal model consist of the usual matter sector with family dependent U'(1) charges, six Higgs weak doublets, and three singlets required to give masses to the Higgsinos and cancel anomalies. We discuss its main features such as the tree level mass spectrum and the constraints on flavor changing processes.

description: ABSTRACT: Increasing workplace diversity is a common goal among many employers, and one primary avenue for improving diversity is through greater recruitment of applicants from minority groups. Given prior research suggesting that minority applicants anticipate being treated with more respect and fairness in workplaces that are already more diverse, we will run a naturalistic field experiment that explores how subtle organizational diversity cues affect the behavior of applicants from both minority and majority groups. In the experiment, participants searching for employment will be exposed to a company with varying levels of racial and gender diversity. We will then investigate whether the decision to submit a job application is impacted by the presence or absence of certain forms of diversity, and if these diversity cues also influence overall applicant quality. Results—and even null results—can advance understanding of current issues related to organizational behavior, employee recruitment, and intergroup processes.

Assessing Carbon Dioxide Euthanasia in Laboratory Rodents
Creators: name: Merenick, Dexter Reece
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Veterinary Science

description: Overdose of carbon dioxide gas (CO2) is a commonly performed euthanasia method for rodents; however, CO2 exposure activates nociceptors in rats and is reported to be painful in humans at concentrations equal or greater than 32.5%. In rats, it is unclear if unconsciousness following CO2 exposure occurs at concentrations below that associated with pain. A standardized loss of righting reflex (LORR) method was applied to identify CO2 concentrations associated with unconsciousness in rats. Additionally, a systematic review examined the consistency and completeness of LORR methods reported in the literature. The results from this thesis show that: 1) strain differences exist in the CO2 concentration required to induce LORR, 2) different LORR assessments can affect the results obtained, and 3) substantial inconsistencies in LORR methodology reporting exist in the literature. These findings raise awareness of strain-specific susceptibilities to CO2 exposure indicating that rat strains have different likelihoods of experiencing nociception and pain. In addition, this research identified longstanding persistent problems in the reporting of LORR methodology. In conclusion, the results from this thesis emphasize potential refinements to CO2 euthanasia and LORR methodological reporting.

description: Massive far-red and infrared imaging surveys in different bandpasses are the main contributors to the discovery of brown dwarfs. The Virtual Observatory represents an adequate framework to handle these vast datasets efficiently and filter them out according to specific requirements. A statistically significant number of BDs is mandatory for understanding their general properties better for identifing peculiar objects. WISE, an all-sky survey in the mid-infrared, provides an excellent opportunity to increase the number of BDs significantly, in particular those at the lower end of the temperature scale. We aim to demonstrate that VO tools are efficient in identifing and characterizing BDs by cross-correlating public catalogues released by large surveys. Using VO tools we performed a cross-match of the WISE Preliminary Release, the 2MASS Point Source and the SDSS Data Release 7 catalogues over the whole area of sky that they have in common ($\sim$ 4000 deg$^{2}$). Photometric and proper motion criteria were used to obtain a list of BD candidates. A temperature estimate is provided for each candidate based on their spectral energy distribution using VOSA, a VO tool for SED fitting. We derive the spectral types from the effective temperatures. Distances, calculated from the absolute magnitude- spectral type relation, place our candidates at 14-80 pc from the Sun, assuming that they are single. We have identified 31 BD candidates, 25 of which have already been reported in the literature. The remaining six candidates have been classified as L- (four) and T-type (two) objects. The high rate of recovery of known BDs ($\sim$ 90% of the T dwarfs catalogued in 2MASS) demonstrates the validity of our strategy to identify them with VO tools.

description: We present a measurement of ppbar->Zgamma->ll+gamma (l = e, mu) production with a data sample corresponding to an integrated luminosity of 6.2 fb^{-1} collected by the D0 detector at the Fermilab Tevatron ppbar Collider. The results of the electron and muon channels are combined, and we measure the total production cross section and the differential cross section dsigma/dp_T^gamma, where p_T^gamma is the momentum of the photon in the plane transverse to the beamline. The results obtained are consistent with the standard model predictions from next-to-leading order calculations. We use the transverse momentum spectrum of the photon to place limits on anomalous ZZgamma and Zgammagamma couplings.

description: The intermetallic FeSi exhibits an unusual temperature dependence in its electronic and magnetic degrees of freedom, epitomized by the crossover from a low temperature non-magnetic semiconductor to a high temperature paramagnetic metal with a Curie-Weiss like susceptibility. Many proposals for this unconventional behavior have been advanced, yet a consensus remains elusive. Using realistic many-body calculations, we here reproduce the signatures of the metal-insulator crossover in various observables: the spectral function, the optical conductivity, the spin susceptibility, and the Seebeck coefficient. Validated by quantitative agreement with experiment, we then address the underlying microscopic picture. We propose a new scenario in which FeSi is a band-insulator at low temperatures and is metalized with increasing temperature through correlation induced incoherence. We explain that the emergent incoherence is linked to the unlocking of iron fluctuating moments which are almost temperature independent at short time scales. Finally, we make explicit suggestions for improving the thermoelectric performance of FeSi based systems.

description: Flames generate a large amount of chemically and thermally ionized species, which are involved in the growth dynamics of particles formed in flames. However, existing models predicting particle formation and growth do not consider particle charging, which may lead to bias in the calculated size distribution of particles. In this study, Fuchs' charging theory was coupled with a monodisperse particle growth model to study the simultaneous charging and coagulation of nanoparticles during combustion. In order to quantify the charging characteristics of nanoparticles, a high-resolution DMA was used to measure the mobilities of ions generated from a premixed flat flame operated at various conditions. The effect of temperature on ion–particle and particle–particle combination coefficients was further examined. The proposed model showed that the influence of charging on particle growth dynamics was more prominent when the ion concentration was comparable to or higher than the particle concentrations, a condition that may be encountered in flame synthesis and solid fuel-burning. Simulated results also showed that unipolar ion environments strongly suppressed the coagulation of particles. In the end, a simplified analysis of the relative importance of particle charging and coagulation was proposed by comparing the characteristic time scales of these two mechanisms. © 2017 American Association for Aerosol Research

description: We present here computational work on the center-of-mass displacements in thin polymer films of finite width without topological constraints and without momentum conservation obtained using a well-known lattice Monte Carlo algorithm with chain lengths ranging up to N=8192. Computing directly the center-of-mass displacement correlation function C_N(t) allows to make manifest the existence of scale-free colored forces acting on a reference chain. As suggested by the scaling arguments put forward in a recent work on three-dimensional melts, we obtain a negative algebraic decay C_N(t) \sim -1/(Nt) for times t << T_N with T_N being the chain relaxation time. This implies a logarithmic correction to the related center-of-mass mean square-displacement h_N(t) as has been checked directly.

description: Full electric-field control of spin orientations is one of the key tasks in semiconductor spintronics. We demonstrate that electric field pulses can be utilized for phase-coherent +/- pi spin rotation of optically generated electron spin packets in InGaAs epilayers detected by time-resolved Faraday rotation. Through spin-orbit interaction, the electric-field pulses act as local magnetic field pulses (LMFP). By the temporal control of the LMFP, we can turn on and off electron spin precession and thereby rotate the spin direction into arbitrary orientations in a 2-dimensional plane. Furthermore, we demonstrate a spin echo-type spin drift experiment and find an unexpected partial spin rephasing, which is evident by a doubling of the spin dephasing time.

Truncation error analysis of unstructured finite volume discretization schemes
Creators: name: Jalali, Alireza
Publisher: name: University of British Columbia
Year: 2012

description: Numerical experiments have proved that numerical errors are at least as large as other sources of error in numerical simulation of fluid flows. Approximating the continuous partial differential equations that govern the behavior of a fluid with discrete relations results in truncation error which is the initial source of numerical errors. Reducing numerical error requires the ability to quantify and reduce the truncation error. Although the truncation error can be easily found for structured mesh discretizations, there is no generic methodology for the truncation error analysis of unstructured finite volume discretizations. In this research, we present novel techniques for the analysis and quantification of the truncation error produced by finite volume discretization on unstructured meshes. These techniques are applied to compare the truncation error produced by different discretization schemes commonly used in cell-centered finite volume solvers. This comparison is carried out for fundamental scalar equations that model the fluid dynamic equations. These equations model both the diffusive and convective fluxes which appear in the finite volume formulation of the fluid flow equations. Two classes of tests are considered for accuracy assessment. Analytical tests on topologically perfect meshes are done to find the general form of the truncation error. Moreover, these tests allow us to eliminate from consideration those schemes that do not perform well even for slightly perturbed meshes. Given the results of the analytic tests, we define a truncation error metric based on the coefficients associated with the spatial derivatives in the series expansion of the truncation error. More complex numerical tests are conducted on the remaining schemes to extend the accuracy assessment to general unstructured meshes consisting of both isotropic and anisotropic triangles. These results will guide us in the choice of appropriate discretization schemes for diffusive and convective fluxes arising from discretization of real governing equations.
Optimization and characterization of asphalts modified with isocyanate modifier

Subjects: subject: Engineering--Civil

description: With the increase of traffic volumes, higher axle loads and harsh climate conditions, the paving industry relies on the use of polymer modified asphalts. With the progress of polymer science and technology, new polymer modified asphalt technologies have emerged. Among the most innovative modification technologies belong the use of B2last, a commercial product of BASF. Unlike other polymer modifiers, B2last is characterized as reactive mono- and oligomeric aromatic diisocyanate. Besides the formation of covalent bonds with polar species present in asphalt, the conversion of B2last into polymer could also be anticipated. In this thesis, a soft conventional asphalt was modified by B2last. The development of modification technology and the effect of B2last on the properties of asphalt was investigated by Superpave binder specification and Fourier-transform infrared spectroscopy (FTIR). The initial Superpave results suggested that B2last had a significant effect on maximum service temperature and resistance to the effects of short-term aging. This could be attributed to the reactive nature of the modification, as the additional oxygen and high temperatures could have led to further conversion of B2last and formation of heavier molecules. Due to the poor performance of B2last modified asphalt in the Multiple Stress Creep and Recovery experiment, the formulations of ternary modified asphalts containing B2last and vulcanized SBS were studied via the Design of Experiments. A positive interaction between the materials was found at high service temperatures, where the thermo-oxidative sensitivity of crosslinked SBS was generally mitigated by the presence of B2last. Lastly, the effect of B2last in paving mixes was evaluated and compared to the performance of hot mix asphalts containing asphalts prepared by a variety of modification technologies. The formulations included asphalt modified with B2last, vulcanized SBS, straight run asphalt with low Pen grade, catalytically oxidized asphalt, and optimized ternary blends containing SBS and B2last. While the samples modified with only vulcanized SBS had a superior performance in several tests, some of the ternary blends showed similar properties while using reduced amounts of total modifiers by weight, leading to the potential formulation of superior performing asphalt mixes with a reduced total content of polymer modifiers.

description: Within an effective Dirac theory the low-energy dispersions of monolayer graphene in the presence of Rashba spin-orbit coupling and spin-degenerate bilayer graphene are described by formally identical expressions. We explore implications of this correspondence for transport by choosing chiral tunneling through pn and pnp junctions as a concrete example. A real-space Green's function formalism based on a tight-binding model is adopted to perform the ballistic transport calculations, which cover and confirm previous theoretical results based on the Dirac theory. Chiral tunneling in monolayer graphene in the presence of Rashba coupling is shown to indeed behave like in bilayer graphene. Combined effects of a forbidden normal transmission and spin separation are observed within the single-band n to p transmission regime. The former comes from real-spin conservation, in analogy with pseudospin conservation in bilayer graphene, while the latter arises from the intrinsic spin-Hall mechanism of the Rashba coupling.

description: Growing up as a South Asian–Sri Lankan student, I recall having a deep desire for cultural representation in school. Even in my own teaching career I struggled to find South Asian music resources, and that eventually compelled me towards research in this field. This study employed an Action Research methodology situated within an anti-colonial framework which allowed me the opportunity to highlight the participants’ positionalities, critically question what music best serves the students of the classroom, resist colonial practices, and institute social change by creating a new way forward. The integration of South Asian music was facilitated using World Music Pedagogy as a pedagogical framework. This framework enabled the inclusion of South Asian and Western pedagogical practices that generated opportunities to compare similarities/differences, build, and recognize interconnections of the socio-cultural-musical contexts of the musics learned. The goal of this research was to create a curricular balance of windows, mirrors, and sliding glass doors in order to accurately reveal and reflect the students’ realities; consequently, enabling for the composition of a culturally responsive classroom in which both teachers and students felt empowered. This study considered the effectiveness of this implementation and how it assisted in the development of the students’ self-identities.

description: Rapid and profound bone loss is a well-known secondary complication following spinal cord injury (SCI), occurring primarily below the level of neurological lesion due to mechanical disuse. The greatest loss of bone is experienced during the acute phase of injury, and established osteoporosis often persists into the chronic phase, with no current standard care plan for patients. The main goals of this thesis were to: (1) explore patient knowledge and awareness regarding bone loss, fracture risk and treatment options following SCI, and (2) to investigate pharmaceutical treatment options to prevent bone loss in acute SCI, as well as treat established osteoporosis in chronic SCI. Three independent studies were carried out and are presented in Chapters 3-5, respectively. Survey results demonstrated that while more than half of participants with SCI were able to correctly answer knowledge-based questions regarding bone health, less than one-fifth had received education on the topic, and approximately three-quarters were interested in learning more about treatment options. Our clinical trials demonstrated the efficacy of zoledronic acid (antiresorptive therapy) to mitigate loss of bone mineral and strength at the hip in acute SCI, regardless of one’s ability to regain ambulation following injury, and the efficacy of romosozumab (anabolic and antiresorptive monoclonal antibody therapy) to increase bone mineral and strength at the hip, but not the knee, in women with chronic SCI. These findings add to the existing body of literature suggesting zoledronic acid is a strong candidate for standard of care to mitigate bone loss during acute SCI, and indicating that further investigation is required to find a treatment that can increase bone mineral, and reduce fracture risk, at both the hip and knee during chronic SCI for those with established osteoporosis.

description: We develop a radiation pressure-balanced model for the interstellar medium of high-redshift galaxies that describes many facets of galaxy formation at z>~6, including star formation rates and distributions and gas accretion onto central black holes. We first show that the vertical gravitational force in the disk of such a model is dominated by the disk self-gravity supported by the radiation pressure of ionizing starlight on gas. Constraining our model to reproduce the UV luminosity function of Lyman-break galaxies (LBGs), we limit the available parameter-space to wind mass-loading factors 1--4 times the canonical value for momentum-driven winds. We then focus our study by exploring the effects of different angular momentum transport mechanisms in the galactic disk and find that accretion driven by gravitational torques, such as from linear spiral waves or non-linear orbit crossings, can build up black hole masses by z=6 consistent with the canonical M-sigma relation with a duty cycle of unity, while accretion mediated by a local viscosity such as in an alpha-disk results in negligible BH accretion. Both gravitational torque models produce X-ray emission from active galactic nuclei (AGN) in high-redshift LBGs in excess of the estimated contribution from high-mass X-ray binaries. Using a recent analysis of deep Chandra observations by Cowie et al., we can already begin to rule out the most extreme regions of our parameter-space: the inflow velocity of gas through the disk must either be less than one percent of the disk circular velocity or the X-ray luminosity of the AGN must be substantially obscured. Moderately deeper future observations or larger sample sizes will be able to probe the more reasonable range of angular momentum transport models and obscuring geometries.

Transferring Transfer Function (TTF): A Guided Approach to Transfer Function Optimization in Volume Visualization

subject: Volume Rendering

description: In volume visualization, a transfer function tailored for one volume usually does not work for other similar volumes without careful tuning. This process can be tedious and time-consuming for a large set of volumes. Leveraging the differentiability of volume rendering, this work presents a novel approach to transfer function optimization based on a reference volume and its transfer function. Using two fully connected neural networks, our approach learns a continuous 2D separable scalar-gradient transfer function that visualizes the features of interest with consistent visual properties across volumes. The resulting optimized transfer function is exportable for further interactions in domain-specific applications. Through two compelling use cases—tracking the aftermath of an asteroid blast near the ocean surface and visualizing brain white matter, grey matter, and cerebral fluid in magnetic resonance (MR) images—we demonstrate the effectiveness of our approach, validated through collaboration with domain experts.

Informal Learning Spaces

description: This is a PPT Presentation at the International Society for the Scholarship of Teaching and Learning (ISSOTL), November 4, 2022. Conference Location: Kelowna, BC, Canada
description: Felton’s (2013) Principles of good practice in SoTL were applied to a study with Indigenous students’ learning experiences in informal settings. The principles: Inquiry focused on student learning (P1); Grounded in context (P2); Methodologically sound (P3); Conducted in partnership with students (P4); and Going public (P5). P1: As a collaborative team of academic librarians and educators, we were curious “how do Indigenous students learn in informal spaces?” We set out to explore Indigenous undergraduate students’ experiences, preferences, and approaches to learning in informal spaces. P2: This SoTL inquiry was conducted at the University of Calgary, a research-intensive Canadian university, with a population of approximately 900 self-identified Indigenous students (2.7 % of the student population). Situated within our University’s Indigenous Strategy this commitment to transformation supports enhanced understanding of Indigenous students’ learning (Brown, 2019). P3: Methodologically sound: Participatory photography, including Photovoice and photo-elicitation methods, was selected as a research framework to explore with Indigenous students (Castleden et. al., 2008). As researchers and co-researchers, we learned together. Photovoice provided students the opportunity to actively engage by taking photos of spaces, documenting and reflecting on their learning and experiences. Photo-elicitation expanded on this with additional participants reflecting on how they learn in various spaces depicted in photos. P4: We intentionally recruited Indigenous students to be co-researchers and made this explicit (Cullinane & O'Sullivan, 2020). As partners we generated the research question, identified how we would work together, and planned the dissemination of our work. P5: The authors have presented at local, national, and international conferences, published two proceedings, and the open-access university platform. An e-book will be written and published by the researchers and student co-researchers. With the knowledge gained in this SoTL research we have data to implement the process of change at our university which advances the goals of the Indigenous strategy.
Life and a lover : lighting an emotional landscape
Creators: name: Huizinga, Sharon
Publisher: name: University of British Columbia
Year: 2012

description: The purpose of this thesis is to document and describe the design process and final lighting design for the University of British Columbia (UBC) production of Life and a Lover. This play was written by Natalie D. Meisner and provides a fictionalized account of Virgina Wolf’s love affair with Vita Sackville West, the subsequent writing of “Orlando,” and eventual suicide. The production opened March 9, 2000 in the Frederic Wood Theatre and ran until March 19, 2000. Kathleen Weiss directed the production and the creative team included Allison Greene (Set Designer), and Kathie Kibble (Costume Designer). The Lighting Design was facilitated by Niven Pong (Assistant Lighting Designer), Don Griffiths (Master Electrician) and UBC undergraduate theatre students. The thesis begins with a summary of the story of the play and a brief background of the historical figure of Virginia Woolf. It then describes the design process conceptually and technically, finally summarizing the effectiveness of the design and the design process, as well as my own experience of the production.
