description: Collisional ring galaxies are the outcome of nearly axisymmetric high-speed encounters between a disc and an intruder galaxy. We investigate the properties of collisional ring galaxies as a function of the impact parameter, the initial relative velocity and the inclination angle. We employ new adaptive mesh refinement simulations to trace the evolution with time of both stars and gas, taking into account star formation and supernova feedback. Axisymmetric encounters produce circular primary rings followed by smaller secondary rings, while off-centre interactions produce asymmetric rings with displaced nuclei. We propose an analytical treatment of the disc warping induced by an inclination angle greater then zero. The star formation history of our models is mainly influenced by the impact parameter: axisymmetric collisions induce impulsive short-lived starburst episodes, whereas off-centre encounters produce long-lived star formation. We compute synthetic colour maps of our models and we find that rings have a B-V colour typically ~0.2 mag bluer than the inner and outer disc, in agreement with observations.

description: Through the lymphatic system’s unique ability to phasically contract, it plays critical roles in maintaining tissue fluid and macromolecular homeostasis, lipid absorption, and immune function. These contractions are promoted by stretch-activation, trigger by increases in intraluminal pressure, leading to an increase in the rate of phasic contractions. Moreover, these phasic contractions are driven by changes in electrical activity and an increase in intracellular calcium levels dependent upon extracellular calcium entry through voltage-dependent calcium channels (VDCCs) and calcium release from the sarcoplasmic reticulum (SR) stores through inositol triphosphate (IP3) receptors. While the involvement of these players in smooth muscle contractions have been well documented, they have not been characterized in lymphatic vessels. Using pressure- and wire-myography, electrophysiology, Polymerase Chain Reaction (PCR) and immunofluorescence imaging, we investigated the role of VDCCs and IP3 receptors on contractile and electrophysiological properties of stretch-activated contractions in isolated rat mesenteric lymphatic vessels.
The Epigraphic Habits of the Slaves and Freed Slaves of the Julio-Claudian Households

description: This study examines the epigraphic evidence and literary texts relating to the slaves, freed slaves, and staff of the households of the Julio-Claudians. Rather than focusing on the Julio-Claudian emperors alone, the integration of their relatives places the Imperial household in its full domestic context, without separating it from other households which shared the same physical space and social situation. While the literary sources provide important context and details, the bulk of the information concerning the Julio-Claudian household comes from the epigraphic material, with nearly 1,800 names surviving. Through the use of rigorous statistical analysis, it becomes possible to achieve a thorough, multifaceted understanding of the Imperial household itself, its early development, and its interactions with other households with which it was closely associated. The epigraphic evidence plainly illustrates the shift from senatorial household to Imperial household, the development of separate domestic and civil service components, and the gradual formation of a new social class of Imperial slaves and freed slaves. Those belonging to the emperors themselves as well as to their relatives shared similar commemorative patterns, particularly with regard to the importance of occupation as a marker of Imperial identity and a way of recording one’s position in the complex occupational hierarchy. Their marriage patterns and the epigraphic habits of their own households illustrated their high social status relative to their peers of equivalent legal status. As for the Julio-Claudian households themselves, there was a great deal of overlap between them, in terms of the transfer of slaves, the sharing of staff, the creation of familial units across household boundaries, and the development of a functional system for running joint households. These Julio-Claudian households tended to specialize in particular areas, strongly delineated by gender: male-owned households had very different gender and occupational distributions of household staff than did female- owned households. This would have prevented occupational redundancy and enabled the smooth and regular integration and dissolution of joint households, emphasizing that elite households – and even the Imperial household – were not intended to function entirely self-sufficiently, but instead within the larger domestic context of the extended family.

description: We report on theoretical Auger electron kinetic energy distribution originated from sequential two-step Auger decays of molecular double core-hole (DCH) state, using CH4, NH3 and H2CO molecules as representative examples. For CH4 and NH3 molecules, the DCH state has an empty 1s inner-shell orbital and its Auger spectrum has two well separated components. One is originated from the 1st Auger transition from the DCH state to the triply ionized states with one core hole and two valence holes (CVV states) and the other is originated from the 2nd Auger transition from the CVV states to quadruply valence ionized (VVVV) states. Our result on the NH3 Auger spectrum is consistent with the experimental spectrum of the DCH Auger decay observed recently [Phys. Rev. Lett. 105, 213005 (2010)]. In contrast to CH4 and NH3 molecules, H2CO has four different DCH states with C1s^{-2}, O1s^{-2} and C1s^{-1}O1s^{-1} (singlet and triplet) configurations, and its Auger spectrum has more complicated structure compared to the Auger spectra of CH4 and NH3 molecules. In the H2CO Auger spectra, the C1s^{-1}O1s^{-1} DCH -> CVV Auger spectrum and the CVV -> VVVV Auger spectrum overlap each other, which suggests that isolation of these Auger components may be difficult in experiment. The C1s^{-2} and O1s^{-2} DCH -> CVV Auger components are separated from the other components in the H2CO Auger spectra, and can be observed in experiment. Two-dimensional Auger spectrum, representing a probability of finding two Auger electrons at specific pair of energies, may be obtained by four-electron coincidence detection technique in experiment. Our calculation shows that this two-dimensional spectrum is useful in understanding contributions of CVV and VVVV states to the Auger decay of molecular DCH states.

description: In this paper we report findings from a study of social network site use in a UK Government department. We have investigated this from a managerial, organisational perspective. We found at the study site that there are already several social network technologies in use, and that these: misalign with and problematize organisational boundaries; blur boundaries between working and social lives; present differing opportunities for control; have different visibilities; have overlapping functionality with each other and with other information technologies; that they evolve and change over time; and that their uptake is conditioned by existing infrastructure and availability. We find the organisational complexity that social technologies are often hoped to cut across is, in reality, something that shapes their uptake and use. We argue the idea of a single, central social network site for supporting cooperative work within an organisation will hit the same problems as any effort of centralisation in organisations. We argue that while there is still plenty of scope for design and innovation in this area, an important challenge now is in supporting organisations in managing what can best be referred to as a social network site 'ecosystem'.

Mass Transfer through Porous Media: Sub-Pore Scale Modeling Approach
Creators: name: Taheri, Saeed
Publisher: name: Graduate Studies
Year: 2013
Subjects: subject: Petroleum
subject: Modeling
subject: Dispersion

description: An important feature of the miscible fluid displacement is the mixing of the solvent and oil. This mixing occurs on the microscopic scale. The mixing has positive and negative effects on the miscible process. It could exert a considerable damping effect on the growth of viscous and gravity fingers as an advantage of the dispersion, on the other hand mixing of the solvent with oil in a reservoir decreases the effective strength of the solvent, which can have a detrimental effect on miscibility and recovery efficiency. Mixing in porous media originates from a complex interaction of molecular diffusion and convective spreading. The diffusion process is governed by the diffusion coefficient. An effective diffusion coefficient is defined for porous media, which has a dependency on the medium properties. Convection spreading could play a major role in accelerating the dilution process by increasing diffusivity and expanding the interface area between the two fluids. The dispersion coefficients are representative of both convective spreading and molecular diffusion lumped together. It is important to know the actual origin of pore-scale mixing but dispersion coefficients describe only the apparent mixing of the medium and do not provide any information about the individual roles played by mechanical dispersion and molecular diffusion over a range of flow conditions and pore geometries at different parts of the porous medium. Based on the sub-pore scale modeling method, a special program has been developed to simultaneously solve the Navier-Stokes, continuity, and general mass transfer equations directly on an image of the porous medium to investigate the mass transfer process considering all medium geometrical properties. The program is capable of predicting the effective diffusion and iii dispersion coefficients for a porous medium under different conditions using just fluid properties and an image of the medium. To study the heterogeneity effect, a pattern generator was developed to generate different patterns of porous media with different geometrical properties. A glass micromodel was built and used to experimentally investigate the miscible displacement process. An image analysis technique was developed to evaluate the results and extract the concentration profiles from the images taken during the test.

description: Quantum algorithms are able to solve particular problems exponentially faster than conventional algorithms, when implemented on a quantum computer. However, all demonstrations to date have required already knowing the answer to construct the algorithm. We have implemented the complete quantum phase estimation algorithm for a single qubit unitary in which the answer is calculated by the algorithm. We use a new approach to implementing the controlled-unitary operations that lie at the heart of the majority of quantum algorithms that is more efficient and does not require the eigenvalues of the unitary to be known. These results point the way to efficient quantum simulations and quantum metrology applications in the near term, and to factoring large numbers in the longer term. This approach is architecture independent and thus can be used in other physical implementations.

description: Psychometric assessment instruments aid clinicians by providing methods of assessing the future risk of adverse events such as aggression. Existing machine learning approaches have treated this as a classification problem, predicting the probability of an adverse event in a fixed future time period from the scores produced by both psychometric instruments and clinical and demographic covariates. We instead propose modelling a patient's future risk using a time series methodology that learns from longitudinal data and produces a probabilistic binary forecast that indicates the presence of the adverse event in the next time period. Based on the recent success of Deep Neural Nets for globally forecasting across many time series, we introduce a global multivariate Recurrent Neural Network for Binary Outcome Forecasting, that trains from and for a population of patient time series to produce individual probabilistic risk assessments. We use a moving window training scheme on a real world dataset of 83 patients, where the main binary time series represents the presence of aggressive events and covariate time series represent clinical or demographic features and psychometric measures. On this dataset our approach was capable of a significant performance increase against both benchmark psychometric instruments and previously used machine learning methodologies.

description: Exploration and development of Canadian natural gas resources is shifting to ultra-low permeability resource plays. Unlike conventional high-permeability gas reservoirs, the flow regime shows a subtle and prolonged transition between early and late time behaviour. Moreover, early time behaviour is strongly impacted by completion techniques. It is inappropriate, or at least very inefficient, to use traditional solutions on the gas resource plays currently under development. To address these issues, this thesis proposes a series of novel analytical and semi-analytical solutions based on Chebyshev polynomial basis functions. The solutions are found using simple and compact computer codes which are included in the text. The solutions cover a variety of flow geometries (1D, 2D, radial and elliptical flow) as well as Dirichlet and Neumann boundary conditions. The simplicity of incorporating Dirichlet boundary conditions makes the method particularly amiable to constant flowing pressure problems. The thesis provides a full description of the theory and mathematical development of the proposed solutions. The thesis also discusses the stability requirements for the proposed solution algorithms, in particular the grid-point requirements for early-time solutions, limitations on time-step lengths and limitations imposed by finite precision mathematical operators. Most significantly, the algorithms developed in this thesis demonstrate significant improvements in numerical efficiency over existing full-life solution techniques, especially for near-wellbore and early-time behaviour. The methods can be used with explicit time stepping algorithms as well as Laplace transform algorithms. This makes the solution methods very flexible and extensible. This opens up new avenues with which to explore and generate fundamental solutions to the diffusivity equation.

The spiritual beliefs of non-religiously affiliated young adults
Creators: name: Rideout, Betty
Publisher: name: University of British Columbia
Year: 2010

description: This qualitative study describes the spiritual beliefs of young adults who have no religious affiliation, and examines how they assess and critically reflect upon their beliefs. An interpretative phenomenological analysis research method was used to describe and thematically organize their spiritual beliefs. Three themes emerged from this analysis: a description of spirituality, the narrative process of creating spiritual beliefs, and the outcomes of possessing spiritual beliefs. Participants describe and define spirituality in diverse ways. The more common definitions include a hopeful and benevolent perspective on life, a tentative acceptance of a higher power, belief in karma and a reverence for nature. One of the most consistent findings is the rejection of institutional religion. Participants choose spirituality to avoid the problems they perceive as being typical to institutional religion and utilize a type of marketplace approach to select spiritual beliefs. Spirituality is construed as a highly individualized narrative process which is related to identity. Spirituality also helps to provide a sense of meaning and purpose. A second level of analysis examined how participants think about and critically reflect upon their beliefs. Elaborative coding, based upon King and Kitchener’s (1994) reflective judgment model, was used to group participants’ assessment of their beliefs into stages, and then interpreted using the reflective judgment model. The findings show that participants’ personal epistemology influence their spiritual beliefs. Moving up the reflective judgment model, spiritual beliefs in the lower stages are explicit, relatively simple beliefs created largely from a dogmatic opposition to religion. Justification for beliefs is based upon unjustified opinion or description, and spirituality is not a central part of their lived experiences. Higher staged participants describe a greater understanding of and appreciation for a constructivist nature of knowledge which contributes to spiritual beliefs that are more complex and grounded in their understanding of epistemology. This study demonstrates the importance of encouraging critical thinking skills in relation to spirituality.
Distributional Effects of Income Transfer Programs and Personal Income Taxes

description: This thesis studies various distributional eﬀects of social transfers and taxation for Canada over the 1993-2008 period using the longitudinal Survey of Labour and Income Dynamics (SLID). It is comprised of four chapters. Chapter 1 examines how changes in the receipt of program beneﬁts, due to reforms in government transfer programs, have aﬀected the income distribution. Chapter 2 examines the relationship between the post- to pre-ﬁscal ratio of income instability, and measures of ﬁscal progressivity and indicators of social insurance. Chapter 3 studies the inequality-reducing role of the tax/transfer system; and chapter 4 presents estimates of earnings dynamics accounting for education. In chapter 1 we apply a nonparametric reweighting decomposition method that reﬂects changes in the probability of receiving program benefits from 1996 to 2006. This method identiﬁes the redistributive role played by transfer programs, and where in the distribution these programs have their greatest eﬀects. We ﬁnd reforms to Social Assistance (SA) reduced its redistributive eﬀectiveness, while Child Beneﬁts, Employment Insurance (EI) and Old Age Security became more redistributive. Chapters 2 and 3 decompose the variance of income into a long- and a short-term component as in the literature on earnings dynamics, using a ﬁve-year rolling window structure. Chapter 2 examines the relationship of the post- to pre-ﬁscal ratio of income instability (E-ratio) with a measure of ﬁscal progressivity, and indicators of social insurance.We find the E-ratio increased substantially after 1998, indicating a turn toward less progressivity, a pattern driven mainly by families with low education earners. The E-ratio of income long-term inequality (permanent variance) is examined in chapter 3. We ﬁnd the tax/transfer system reduces the permanent variance for earners with less than High School. The provision of SA is more eﬀective in reducing long-term inequality than EI. Chapter 4 presents the ﬁrst estimates of earnings dynamics accounting for education and using the SLID for Canada. Instability and inequality are the greatest for the less educated, and grew rapidly in the late 1990s. Since 2001, inequality increased among earners with college and university degrees.

The corresponding Green's kernel is found and from this wave dispersion dependencies are obtained in explicit form. An equation of the Wiener-Hopf type is also derived and solved along the crack face, in order to compute the stress intensity factor for the semi-infinite crack. The crack stability is analysed via the evaluation of the energy release rate for different contrasts in stiffness of the bonds.

description: This thesis proposes an approach to solve multi-objective optimization problems in power systems based on the Extended Goal Programming (EGP) method. In the first part, the EGP method is applied to deterministic multi-objective optimal power flow (MOOPF) problem. The results are compared with classical methods and the efficiency of the EGP method is evaluated. A method for ranking the solutions is introduced to help decision makers choose their preferred solution. In the second part, Taguchi's Orthogonal Array Technique (TOAT) and EGP method are jointly applied to solve probabilistic MOOPF problem with load and renewable generation uncertainties. This approach finds a solution that is robust to uncertain variations in load and renewable power generations. An analysis of the significance of generators ramp rate variation with the degree of robustness of the solution is shown. The results are compared with that of deterministic model and the robustness of the solution is evaluated.

description: LPS activates TLR4 signaling pathway eliciting antiviral host responses in mammals although information on such responses in avian species is scarce. Objectives of the work described in the thesis were to 1. characterize the LPS induced expression of LPS receptors and NO in two avian cell lines, LMH and MQ-NCSU, and 2. observe whether NO can elicit antiviral response against ILTV replication. We found that LPS was capable of inducing the expression of TLR4, CD14 and NO production only in MQ-NCSU cells. We also showed that TLR4 mediated NO production in MQ-NCSU cells confers antiviral response against ILTV in susceptible LMH cells. Using a selective inhibitor of inducible NO synthase and a NO donor as a source of NO, we confirmed that this effect is positively correlated with NO. Our data showed that LPS can be a potential innate immune stimulant that can be used against ILTV infection in chickens.
Desperately seeking redundancy? : queer romantic comedy and the festival audience
Creators: name: Penney, Renee
Publisher: name: University of British Columbia
Year: 2010

description: Historically speaking, the queer film festival is rooted in grassroots politics and it exists as a counterculture space. Conversely, genre cinema is associated with classical Hollywood and it is largely associated with mainstream, heteronormative value systems. The queer romantic comedy represents a major flashpoint as a crossover phenomenon: in its ability to infiltrate these diametrically opposed cultural systems, it is viewed as both traitor and arbitrator simultaneously. The response to this queered genre is directly related to critical debates surrounding the question of whether the queer film festival space has become or seeks to become redundant. Ironically, while the question of redundancy circulates, critical analysis of the queer film festival space has only recently begun to emerge, while the queer romantic comedy itself is virtually nonexistent within genre theory. As such, I argue that the queer film festival and the queer romantic comedy are inextricably linked as sites of transgression, and that, neither are becoming redundant. To construct my analysis, I use the Vancouver Queer Film Festival as a blueprint for the selection of gay and lesbian romantic comedies. I cite a number of critical thinkers, however, key to my analysis are a series of forums on the queer film festival published in GLQ: A Journal of Lesbian and Gay Studies, as well as Rick Altman’s genre theory and Bakhtin’s concept of carnival. In chapter two, I provide an historical overview of the Vancouver Queer Film Festival and outline my primary data for analysis. In chapter three, I draw from the GLQ forums to contextualize key debates surrounding the changing role of the queer iii film festival. In chapter four, I insert queer romantic comedy into the lexicon of genre theory to explore the use of self-reflexivity as a political tool. In chapters five and six, I compare the gay and lesbian romantic comedy collections, focusing on primary tropes, modes of address and media response to locate points of disruption within these ‘generic’ texts. In the concluding chapter, I consider the question of redundancy in relation to actual and authorized transgression within queer romantic comedy and the queer film festival space.

description: We make a thermal analysis of the light scalar susceptibilities using SU(3)-Chiral Perturbation Theory to one loop taking into account the QCD source of isospin breaking (IB), i.e corrections coming from $m_u\neq m_d$. The value of the connected scalar susceptibility in the infrared regime, the one relevant when approaching chiral symmetry restoration, and below the critical temperature is found to be entirely dominated by the $π^0-η$ mixing, which leads to model-independent $\mathcal{O}(ε^0)$ corrections, where $ε\sim m_d-m_u$, in the combination $χ_{uu}-χ_{ud}$ of flavour breaking susceptibilities. We also present preliminary results for the corrections to the real part of the pion self-energy at nexst-to-leading order in SU(2)-Chiral Perturbation Theory taking into account electromagnetic interaction. The zero and finite temperature results for the charged and neutral pions are given in terms of the three-momentum of the external pion; and their difference is calculated to this order stressing the fact that, at low and moderate temperature, the mass splitting $M_{π^\pm}-M_{π^0}$ grows with temperature for, at least, non-zero charged pion mass running inside the loops.

description: Hyperspectral salient object detection (HSOD) aims to detect spectrally salient objects in hyperspectral images (HSIs). However, existing methods inadequately utilize spectral information by either converting HSIs into false-color images or converging neural networks with clustering. We propose a novel approach that fully leverages the spectral characteristics by extracting two distinct frequency components from the spectrum: low-frequency Spectral Saliency and high-frequency Spectral Edge. The Spectral Saliency approximates the region of salient objects, while the Spectral Edge captures edge information of salient objects. These two complementary components, crucial for HSOD, are derived by computing from the inter-layer spectral angular distance of the Gaussian pyramid and the intra-neighborhood spectral angular gradients, respectively. To effectively utilize this dual-frequency information, we introduce a novel lightweight Spectrum-driven Mixed-frequency Network (SMN). SMN incorporates two parameter-free plug-and-play operators, namely Spectral Saliency Generator and Spectral Edge Operator, to extract the Spectral Saliency and Spectral Edge components from the input HSI independently. Subsequently, the Mixed-frequency Attention module, comprised of two frequency-dependent heads, intelligently combines the embedded features of edge and saliency information, resulting in a mixed-frequency feature representation. Furthermore, a saliency-edge-aware decoder progressively scales up the mixed-frequency feature while preserving rich detail and saliency information for accurate salient object prediction. Extensive experiments conducted on the HS-SOD benchmark and our custom dataset HSOD-BIT demonstrate that our SMN outperforms state-of-the-art methods regarding HSOD performance. Code and dataset will be available at https://github.com/laprf/SMN.

description: Precise stellar radial velocities are used to search for massive (Jupiter masses or higher) exoplanets around the stars of the open cluster M67. We aim to obtain a census of massive exoplanets in a cluster of solar metallicity and age in order to study the dependence of planet formation on stellar mass and to compare in detail the chemical composition of stars with and without planets. This first work presents the sample and the observations, discusses the cluster characteristics and the radial velocity (RV) distribution of the stars, and individuates the most likely planetary host candidates. We observed a total of 88 main-sequence stars, subgiants, and giants all highly probable members of M67, using four telescopes and instrument combinations. We investigate whether exoplanets are present by obtaining radial velocities with precisions as good as 10 m/s. To date, we have performed 680 single observations (Dec. 2011) and a preliminary analysis of data, spanning a period of up to eight years. Although the sample was pre-selected to avoid the inclusion of binaries, we identify 11 previously unknown binary candidates. Eleven stars clearly displayed larger RV variability and these are candidates to host long-term substellar companions. The average RV is also independent of the stellar magnitude and evolutionary status, confirming that the difference in gravitational redshift between giants and dwarfs is almost cancelled by the atmospheric motions. We use the subsample of solar-type stars to derive a precise true RV for this cluster. We finally create a catalog of binaries and use it to clean the color magnitude diagram (CMD). As conclusion, by pushing the search for planets to the faintest possible magnitudes, it is possible to observe solar analogues in open clusters, and we propose 11 candidates to host substellar companions.

description: Reports of the death of the precursor of Supernova (SN) 1961V in NGC 1058 are exaggerated. Consideration of the best astrometric data shows that the star, known as "Object 7," lies at the greatest proximity to SN 1961V and is the likely survivor of the "SN impostor" super-outburst. SN 1961V does not coincide with a neighboring radio source and is therefore not a radio SN. Additionally, the current properties of Object 7, based on data obtained with the Hubble Space Telescope, are consistent with it being a quiescent Luminous Blue Variable (LBV). Furthermore, post-explosion non-detections by the Spitzer Space Telescope do not necessarily and sufficiently rule out a surviving LBV. We therefore consider, based on the available evidence, that it is yet a bit premature to reclassify SN 1961V as a bona fide SN. The inevitable demise of this star, though, may not be too far off.

description: In many engineering and industrial applications, such as oil and bitumen recovery, in situ upgrading, coal gasification, soil remediation and many others, chemical reactions take place in porous media. However, numerical simulation of reactive flow to predict the behavior of such systems under various conditions is a challenging task. One of these challenges arises from the multiscale nature of reactive and associated diffusive processes. The chemical reactions are responsible for the generation of sharp temperature and concentration fronts in the media. The common numerical schemes have difficulty in capturing these steep fronts, unless very fine grid numerical schemes are utilized, which increases the computational expenses considerably and is not achievable in many practical cases, such as oil and gas reservoir simulations. One of the remedies for this problem is the development of upscaling methods to account for small-scale processes and capture their effects in coarse grid simulation schemes, thereby increasing computational speed. These methods should not compromise accuracy, maintain the realistic nature of the numerical model at an acceptable level and account for the important effects of the reactions. In this research, our main objective was the development of equivalent reaction constants to capture small-scale phenomena and modify them so that they can be implemented into coarse-scale numerical simulations. Several different reactive systems were studied including solid-solid and gas-solid reactions. The effects of a correction parameter for coarse grid simulation of these systems were investigated, and it was concluded that this factor was only applicable for a constant front pattern of solid-solid systems and it did not improve the coarse grid simulation of strongly convective-dominant reactive systems, such as gas-solid ones. Furthermore, in this study, an equivalent reaction kinetics constant for a system consisting of diffusion and convection with power law kinetics under isothermal and steady-state conditions was developed. Based on this research, type curves were developed for obtaining the equivalent reaction parameter for coarse grid simulation. In addition, approximate analytical solutions and subsequently analytical expressions were developed for obtaining the equivalent reaction constants in non-isothermal conditions. These solutions were developed for various conditions.
Essays on Taxation and Investment
Creators: name: Krzepkowski, Matt
Publisher: name: Graduate Studies
Year: 2013
Subjects: subject: General
subject: Finance
subject: Economics

description: This thesis examines the importance of taxation on firm investment. The thesis shows that low tax rates are effective at increasing investment in an international context, but also that the design of tax system can cause significant distortions in the incentives for firms to invest. The first chapter of this thesis shows the significance of the complete tax system, outside of simple corporate statutory tax rates, on determining foreign investment inflows. The second chapter shows how government intervention in the credit market can have positive or adverse effects on the investment and risk-taking of small businesses. The final chapter looks at how the corporate tax system's treatment of corporate losses affects the incentive for firms to invest based on their profitability. The thesis provides new understanding of the importance of tax design in affecting firm investment behaviour.
Disclosing National Identity Within National Debate: The Study of Social and Political Ideologies in Canadian Climate Change Rhetoric
Creators: name: Kingdon, Julia
Publisher: name: Graduate Studies
Year: 2013
Subjects: subject: Rhetoric and Composition
subject: Rhetoric
subject: Ideology
subject: climate change

description: This thesis examines the ideological rhetoric of Canadian climate change discourse to understand how such communication may be influencing certain perspectives towards Canadian identity and affecting the Canadian government’s policy approaches to climate change. An ideological rhetorical critique is applied to the rhetoric of the NRTEE, Greenpeace, and the Friends of Science to determine the ideologies and identities being rhetorically articulated within these pivotal perspectives of Canada’s climate change discourse. This thesis also identifies ideological similarities between each of the three organizations’ climate change rhetoric, and discloses the similarities between their rhetorical constructions of Canadian identity. The finding of shared ideologies and versions of Canadian identity demonstrates how ideological rhetorical analysis can function to create solidarity even amongst the most polemical of parties. The methods and findings of this thesis also function to exemplify the initial means through which a representative and inclusive Canadian climate policy could be derived.
Constraints on Obscured Star Formation in Host Galaxies of Gamma-ray Bursts

description: We present the results of the 16-cm-waveband continuum observations of four host galaxies of gamma-ray bursts (GRBs) 990705, 021211, 041006, and 051022 using the Australia Telescope Compact Array. Radio emission was not detected in any of the host galaxies. The 2sigma upper limits on star-formation rates derived from the radio observations of the host galaxies are 23, 45, 27, and 26 Msun/yr, respectively, which are less than about 10 times those derived from UV/optical observations, suggesting that they have no significant dust-obscured star formation. GRBs 021211 and 051022 are known as the so-called "dark GRBs" and our results imply that dark GRBs do not always occur in galaxies enshrouded by dust. Because large dust extinction was not observed in the afterglow of GRB021211, our result {\bf suggests the possibility} that the cause of the dark GRB is the intrinsic faintness of the optical afterglow. On the other hand, by considering the high column density observed in the afterglow of GRB051022, the likely cause of the dark GRB is the dust extinction in the line of sight of the GRB.

The Romantic View of Nature and the Conspiracy Theory in Environmental Documentaries
Creators: name: Orda, Olga
Publisher: name: Graduate Studies
Year: 2012
Subjects: Mass Communications

description: This project argues that environmental documentaries of the 2000s promote harmful Romantic views of nature and produce overly simplistic knowledge about the causes of global environmental degradation through the use of the conspiracy theory. By analyzing the rhetorical and ideological features of environmental documentaries through the tradition of scholars who write on the Romantic views of nature and the conspiracy theories, this project’s methodology will allow us to see how environmental documentaries frame nature and environmental problems in ways that are overly simplistic and even harmful to the advancement of the environmental movement itself. Ultimately, this project contributes a unique analysis not only of environmental films, but more importantly, the types of definitions of nature and environmental problems that circulate and that are perpetuated in popular culture and environmental movement circles.

description: This thesis examines sacred place and the potential these places hold as catalysts for positive change in the lives of spiritual individuals and religious communities throughout Canada. In order to better understand sacred place and the demand these places will continue to have, this thesis explores religious and spiritual trends within Canada. A number of sacred places--shared sacred places--were identified as useful examples based on the religious and spiritual context in Canada. Site visits were conducted, including site analysis and key-informant interviews, to better understand the effectiveness of these particular types of sacred places. A framework for designing sacred places, termed “sacred placemaking,” is developed to assist decision makers—architects, designers, Chaplains, planners, and administrators—with the design and facilitation of sacred place. A toolkit is developed as an accompaniment to this thesis, and is intended as a refined booklet of considerations for the design of sacred places.
