description: This thesis develops a detailed environmental-economic model of the province of Alberta. Methods are developed for utilizing a variety of statistical data sources to develop disaggregate provincial input-output models based on the national Canadian model. The model is extended to include physical flows of water, energy, and greenhouse gas emissions. A new approach to distributing physical flows is developed that considers physical flows as derived demands to satisfy the needs of utility maximizing industrial and household activities. This framework is applied to analysis of carbon pricing at the provincial scale and results presented. Detailed representations of household consumption and electricity generation are utilized to better assess the effects of carbon pricing and where redistributive measures should be applied. The model is then applied to assessment of three technology change scenarios: a shift in the provincial electricity generation mix, a transition to a fully electric private automobile fleet, and a partial change in the non-residential construction industry to reduce concrete use and increase use of wood in construction.

description: In models of emergent gravity the metric arises as the expectation value of some collective field. Usually, many different collective fields with appropriate tensor properties are candidates for a metric. Which collective field describes the "physical geometry"? We resolve this "metric ambiguity" by an investigation of the most general form of the quantum effective action for several metrics. In the long-distance limit the physical metric is universal and accounts for a massless graviton. Other degrees of freedom contained in the various metric candidates describe very massive scalars and symmetric second rank tensors. They only play a role at microscopic distances, typically around the Planck length. The universality of geometry at long distances extends to the vierbein and the connection. On the other hand, for distances and time intervals of Planck size geometry looses its universal meaning. Time is born with the big bang.

description: Introduction: The prevalence of obesity may have reached a plateau in some developed countries and become more complex and intractable in many developing countries. Poor diet patterns are found to be prospectively associated with an increased risk of adolescent obesity. The aim of this study is to determine the association of having frequent meals towards obesity among Malaysian school-going adolescents in urban areas. Methodology: This study used the data from National Health Morbidity Survey (NHMS) 2017, a nationwide cross-sectional survey that implemented a two-stage stratified random sampling design. A total of 23,463 adolescents age between 10 to 17 years old from the urban area were involved. Complex samples logistic regression analyses were then performed to estimate the odds of being obese according to the meal type using the SPSS software version 25. Meal patterns are used to describe individuals' eating patterns at a different level of a meal including breakfast, lunch, dinner, or a smaller-sized meal like supper or snack in a week. Results: The finding shows that 6.6% of adolescents were categorized as thin, 62.3% normal, 16.2% overweight and 15% obese in the urban area. Total number of obese adolescents were 3,496 (male = 60.2%, female = 9.8%). The finding shows very strong evidence of relationship between meal pattern and obesity with breakfast (p<0.001), lunch (p<0.016), dinner (p<0.001), and supper (p<0.001). Discussion/conclusion: This study showed that the prevalence of obesity among Malaysian urban adolescents was quite high with estimating of 1 in every 7 adolescents found to become obese. Obesity was found to be higher among males and Bumiputera Sarawak. The study has limitations since it concentrated on the relationship between obesity and food intake effects without taking into account other possible causes. Awareness programmes and activities on obesity and healthy meal pattern need to be improved especially among primary and secondary students.

description: Emerging in the 1970s, the White Nationalist movement resurfaced in the late 2010s with the election of President Donald J. Trump. This far-right White supremacist movement is a breeding ground for domestic terrorist groups, and lone-wolf attackers. White Nationalism is predicated on the belief in White racial superiority and the belief that White people need a racial homeland in order to survive. Originally sparked as part of the White backlash to the Civil Rights movements and Black Power movements of the 50s and 60s, the ideas that animate this racialist movement go back even further. Analyzing the trajectory of White supremacist ideas and violent White Nationalist groups since before the 1970s is vital for understanding the re-emergence of the White Nationalist movement and the real political impacts this ideology is having in early twenty-first century American society. This thesis seeks to understand this re-emergence by analyzing how White Nationalist thought has evolved, and the ways that White Nationalist groups use gender-based appeals to recruit members and promote their ideology. This movement and its ideology have been attractive to disaffected White men who believe that society has passed them by and who may be experiencing what scholars have called a "crisis of masculinity." This thesis will examine how the White Nationalist movement has used the concept of masculinity in its publications, literature, and counter-media. The White Nationalist movement relies on propaganda that promotes the idea that the White race is in danger of going extinct, and that the White race needs saviours and protectors. In this way White Nationalist propaganda makes appeals to the manhood of their target audience while also promoting racial animosity and hatred. Their propaganda also relies upon scapegoating and the demonization of "others." This movement has been growing since the 1970s and has become influential due to the success of White Nationalist groups using the Internet to promulgate their ideas. This thesis seeks to understand the history of this radical ideology and the ways that this movement has used appeals to masculine identity to reach new adherents.

description: Calgary is a leading Alberta municipality in low impact development (LID). This thesis provides a discussion and analysis of Calgary’s transition to the LID approach to stormwater management. The drivers of change that preceded the introduction of LID to Calgary are examined. Research includes in-depth assessment of interwoven federal, provincial, regional and municipal regulatory and policy aspects, as well as interviews with practicing stormwater management professionals. The natural hydrological regime (created by Calgary's cold, semi-arid climate, Chinooks, post-glacial topography and dense clay soils) relies on evaporation and evapotranspiration, rather than infiltration for pre-development stormwater processes. The goal of the city’s Stormwater Management Strategy is to improve post-development stormwater quality and minimize morphological impact on the receiving waters. In April 2014, Calgary adopted Interim Stormwater Targets based on pre-development peak and annual volume discharge per unit area. LID remains an evolving field, with many challenges yet to be overcome.

description: Introduction: Blindness and visual impairment are part of a global burden of eyes disease. The leading causes of blindness were cataracts, followed by glaucoma, age-related macular degeneration, and diabetic retinopathy. The effective way to treat cataract which causes visual impairment is cataract surgery. It is the most common ocular procedure performed in the world. Objective: The aim of this study is to determine the factors affecting the improvement of visual acuity (VA) among cataract patients after surgery in Malaysia. Methodology: This was a retrospective cohort study. Cataract patients who underwent surgery and were registered from January 2014 to December 2018 with age over 18 years old were extracted from database. Ordinal logistic regression was used to identify the association between the factors and the outcome. Result presentation using odds ratio and 95% confidence interval (CI).  Result: A total of 199,826 patients were analyzed. Multivariable analysis showed improvement of VA was significantly higher in patients with age group 41-60 years old (OR: 1.30; 95% CI: 1.04, 1.63), female patients (OR: 1.07; 95% CI: 1.01, 1.13), Malay groups (OR: 1.61 95% CI: 1.51, 1.70) and developmental cause of cataract (OR: 1.79 95% CI: 1.10, 2.92). Odds of no ocular comorbidity were 68% (OR: 1.68; 95% CI: 1.58, 1.78) higher in vision improvement. Intraoperative and postoperative complications had 1.21(95% CI: 1.08,1.34) and 10.85(95% CI: 10.24,11.51) times higher odds of im-proving VA. Surgery using ECCE with a presence of IOL and performed quickly gave a good result. Older age, gender of female, ethnicity, the primary cause of cataract, absence of ocular comorbidities, Surgeon Grade, surgery type, shortest of duration surgery, presence of IOL, absent of intraoperative complication, and absent of postoperative complication are the factors that affect to be worse to improve VA after undergoing cataract surgery. Discussion/conclusion: The model from ordinal logistic regression demonstrated that age between 41 to 60 years, gender of female, Malay ethnicity, absence of ocular comorbidities, surgery using ECCE, shortest of duration surgery, presence of IOL, absent of intraoperative complication, and absent of postoperative complication are the factors that affect to be worse to improve VA after undergoing cataract surgery. These findings can provide evidence-based information for relevant clinicians and policymakers in planning and implementing interventional programs.

Publisher: name: Graduate Studies
Year: 2017
Subjects: Engineering--Petroleum

description: This research justifies the improvement of the oil recovery by using the water alternating CO2 flooding method for the right candidates, also indicates the importance of considering relative permeability hysteresis effects in WAG numerical simulations. Good reservoir candidates for water alternating CO2 injection have been prepared in this study considering different wettability characteristics (oil-wet and water-wet) and different oil viscosities. In addition, some simulations have been performed on the models with severe permeability distribution in their layers. First, it was shown that CO2-WAG (water alternating gas) results in much higher oil production in all the simulations compared to water flooding or CO2 flooding. Then CO2-WAG simulations were conducted with and without considering the relative permeability hysteresis effects. It was concluded that the models with the hysteresis effects have higher oil production for different scenarios of oil viscosity and reservoir wettability. Moreover, including hysteresis effects has bigger impacts on the oil production in the cases of low viscosity oil and a severe permeability reservoir. Finally, water flooding and CO2 flooding worked differently with respect to the rock and fluid properties such as reservoir permeability distribution and oil viscosity.

description: Cellular assays are essential in pharmaceutical development of protein-loaded nanomedicine. Cell lines provide robust and efficient models to characterise cytotoxicity, cellular uptake, absorption mechanism, intracellular stability, exocytosis mechanism and therapeutic effects of nanomedicine. GI epithelial cells and goblet cells have been employed to examine protein-loaded nanoparticles in vitro. However, the existence of different research protocols hampers the comparison of formulations and obtained results. Although advanced novel microscopy and fluorescent detection techniques are available for facilitating the development of nano-sized formulation, optimised research designs and validated instrument operation procedure are crucial to increase the reliability and validity of research findings. In the current review article, we examined a number of cellular assays, including cellular culture, cytotoxicity assay, cellular uptake assay, transepithelial studies, permeability assays, glucose consumption assays, and exocytosis and endocytosis studies, that have been widely employed for the development of orally administered insulin-loaded nanoparticles. Meanwhile, the role of various technologies, such as CLSM, flow cytometry, ELISA, fluorescence microscopy, microplate reader, and transmission electron microscopy, on visualisation of nanoparticle cellular uptake was evaluated. The following four challenges, including limited nanoparticle diffusion across mucus barrier, unwanted apical exocytosis, P-glycoprotein efflux pumps, endosomal entrapment and lysosomal degradation on protein-loaded nanoparticles, should be addressed in future studies. During formulation optimisation, strategies that can overcome the above hinderance are warranted to maximise oral bioavailability, minimise waste in research funding and facilitate the translation of therapeutic protein-loaded nanomedicine into clinical settings.
Nursing care and post-operative delirium in the cardiac surgery intensive care unit
Creators: name: Taipale, Priscilla Gail
Publisher: name: University of British Columbia

description: Post-operative delirium is a debilitating and costly adverse event that has detrimental effects on patients’ recovery and complicates nursing care. Its numerous risk factors make the disorder seem unavoidable and unpreventable. Although pre-operative and intra-operative risk factors for delirium may not be controllable, the post-operative risk factors directly related to nursing practice are directly controllable. Practices to control pain through analgesia and sedation administration given at nurses’ prerogative may be associated with the onset of delirium in the immediate post-operative period. This study examined opioid and benzodiazepine administration given pro-re-nata (PRN) (“as needed”) by nurses to cardiac surgery patients to determine whether a relationship exists between delirium and nurses’ drug administration. One hundred twenty-two patients were assessed during the first three days following cardiac surgery for delirium with the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Data were collected regarding potential risk factors and opioid analgesia and benzodiazepine dosages given to the patients. A retrospective chart review was conducted to determine whether the patients had a physician’s clinical assessment and diagnosis of delirium. Post-operative delirium occurred in 37.7% to 44.3% of the study sample, depending on how the cases that had positive CAM-ICU assessments and no clinical diagnoses of delirium were handled. The amount of opioid analgesia given to these patients varied widely; however, the total dosage over the 72-hour study period had no statistically significant relationship with the development of delirium (Median = 77.2 morphine equivalents (MEs) for group without delirium vs. 79.3 MEs for group with delirium; Mann-Whitney U = 1697, Z = -0.72, p = .47). The amount of Midazolam administered also varied widely. There was a statistically significant and positive relationship between the dosage of Midazolam given and the development of post-operative delirium (Median = 2.0 mg. for group without delirium vs. 4.0 mg. for group with delirium; Mann-Whitney U = 1393, Z = -2.31, p = .021). The results of this study indicate that better nursing education and changes in nurses’ practice may be required to protect patients from experiencing drug-induced post-operative delirium.
Examining the Influence of Sensorimotor Experience on 5-year-old Children's Word Learning

description: According to strong theories of embodied cognition, sensorimotor experience is essential for gaining, representing, and accessing conceptual knowledge. The role of embodied knowledge in adult language processing has been studied quite extensively, and embodied experiences are considered necessary for infants’ early learning. The effect of sensorimotor experience in older children’s language learning, however, has been examined to a much lesser extent. I conducted two experiments with 5-year-old children to examine the influence of sensorimotor interaction on object label learning. In Experiment 1, children learned labels for ten novel objects in one of four learning conditions: active interaction, observe interaction, object observation, or object observation with fact. The children were then given a recognition test, and the results indicated that there was no effect of learning condition on recognition accuracy. Children in the active interaction condition did make more comments during the learning phase about how the objects could be manipulated, and this focus on object function could have distracted from their ability to learn the object labels. In Experiment 2, I modified the stimuli so that they did not afford any obvious functions and so that the sensory features of the objects were emphasized. Children again learned labels for ten novel objects in one of two learning conditions: active interaction or object observation. Once again, there was no effect of learning condition on recognition accuracy performance. Taken together, the findings provide some insight into the role of embodied experience in children’s language learning. More specifically, the results provide evidence against strong theories of embodied cognition by demonstrating a situation in which sensorimotor experience did not benefit learning.
Curvature perturbation from velocity modulation

description: We propose a new variant model of the modulated reheating. If particles have large scale fluctuations on their velocities, or equivalently their Lorentz factors, the decay rate also fluctuates and the curvature perturbation is induced via their decay processes in analogy with modulated reheating. For example, if they are produced nonthermally by the decay of another field with its mass fluctuating on large scales, such a situation is realized. We explicitly calculate the resulting curvature perturbation and non-linearity parameters and show that the effect of velocity-modulation is not negligible if the particles are semi-relativistic at the decay.

description: Infrared spectra in the carbon monoxide CO stretch region (~2150 cm−1) and in the nu3 asymmetric stretch region of N2O (~2223 cm−1) are assigned to the previously unobserved O-bonded form of the CO-N2O dimer (“isomer 2”). This van der Waals complex has a planar skewed T-shaped structure like that of the previously observed C-bonded form (“isomer 1”), but with the CO rotated by 180°. In addition to the fundamental band, combination bands for both isomers are observed and intermolecular frequencies for the out of plane torsion and the in-plane CO-rock, or disrotatory bend are reported. Vibrational assignment of these bands is achieved by comparison with data recently published (A. Barclay et al., Chem. Phys. Letters, 651 (2016) 62), concerning OC-CO2. We show that the most recent ab initio potential energy surface is inadequate in predicting the intermolecular frequencies for both isomers (CO-N2O and OC-N2O).
Can some simple games lead to chaos?

description: Some combinatorial games, like GRUNDY'S GAME, are simple to describe, but follow chaotic patterns and can prove very difficult to analyze entirely. In this thesis we will look at some games, including a combinatorial version of Mancala; the game of BLASH & SLASH, played by drawing diagonals on a rectangular grid; and BLASH, SLASH & DASH, played by removing edges in triangular arrays. While some of these games might seem very simple at a first, they often exhibit patterns that are very hard to predict. In Chapters 1 and 2 we give an introduction to the subject of combinatorial games by looking at the theories crafted by Conway and by Sprague and Grundy before him. In Chapter 3 we analyze the game of BLASH & SLASH in some of its versions, and find an equivalence between this game and NODE KAYLES. In Chapter 4 we look at the game of BLASH, SLASH & DASH and find a sparse space in one of its cases. In Chapter 5 we analyze some versions of BASIC MANCALA. Lastly, we give suggestions for future research in these games.

description: Models for GRB outflows invoke turbulence in relativistically hot magnetized fluids. In order to investigate these conditions we have performed high-resolution three-dimensional numerical simulations of relativistic magneto-hydrodynamical (RMHD) turbulence. We find that magnetic energy is amplified to several percent of the total energy density by turbulent twisting and folding of magnetic field lines. Values of epsilon_B near 1% are thus naturally expected. We study the dependence of saturated magnetic field energy fraction as a function of Mach number and relativistic temperature. We then present power spectra of the turbulent kinetic and magnetic energies. We also present solenoidal (curl-like) and dilatational (divergence-like) power spectra of kinetic energy. We propose that relativistic effects introduce novel couplings between these spectral components. The case we explore in most detail is for equal amounts of thermal and rest mass energy, corresponding to conditions after collisions of shells with relative Lorentz factors of several. These conditions are relevant in models for internal shocks, for the late afterglow phase, for cocoon material along the edge of a relativistic jet as it propagates through a star, as well neutron stars merging with each other and with black hole companions. We find that relativistic turbulence decays extremely quickly, on a sound crossing time of an eddy. Models invoking sustained relativistic turbulence to explain variability in GRB prompt emission are thus strongly disfavored unless a persistant driving of the turbulence is maintained for the duration of the prompt emission.

On the phase of quark determinant in lattice QCD with finite chemical potential

description: We investigate the phase of the quark determinant with finite chemical potential in lattice QCD using both analytic and numerical methods. Applying the winding number expansion and the hopping parameter expansion to the logarithm of the determinant, we show that the absolute value of the phase has an upper bound that grows with the spatial volume but decreases exponentially with an increase in the temporal extent of the lattice. This analytic but approximate result is confirmed with a numerical study in four-flavor QCD in which the phase is calculated exactly. Since the phase is well controlled on lattices with larger time extents, we try the phase reweighting method in a region beyond $μ/T=1$ where the Taylor expansion method cannot be applied. Working in four-flavor QCD, we find a first-order like behavior on a $6^3\times 4$ lattice at $μ/T\approx 0.8$ which was previously observed by Kentucky group with the canonical method. We also show that the winding number expansion has a nice convergence property beyond $μ/T=1$. We expect that this expansion is useful to study the high density region of the QCD phase diagram at low temperatures.

description: This thesis surveys a pair of topics which both depend on holomorphic functions and Banach Algebras. Firstly, the prerequisite background knowledge common to both such as holomorphic functions, Banach spaces and algebras, and module theory is provided. Secondly, KMS states arising on Cuntz-Krieger algebras are described. A Cuntz-Krieger graph algebra A is the universal C^* algebra satisfying certain defining relations between its partial isometries p_v which are derived from the directed graph. It becomes a C^* dynamical system when equipped with a gauge action a_t defined on partial isometries by a_t(p_v) = e^{it}p_v. Its KMS states can now be studied. (The KMS condition arises in physics in which it is a local equilibrium condition for the states of the operator algebra generated by local observables with the action of conjugation by the (time) evolution operator U_t = e^{it H}.) Examples including KMS states on matrix algebras and the generalization of Cuntz-Krieger algebras to Cuntz-Pimsner algebras are provided. Thirdly, algebras of bounded holomorphic functions are discussed. The maximal ideal space for an algebra of bounded holomorphic functions on a Riemann surface R is described. (In particular, this holds for domains in the complex plane C.) By the correspondence between maximal ideals and algebra homomorphism to $\mathbb{C}$, the maximal ideal space may be equipped with its induced weak* topology which is known as the Gelfand topology. A couple of interesting problems are the corona problem and the complement problem. The corona problem concerns whether the point evaluations (functionals induced by the canonical map R \to H^(R)*) are weak-star dense in the algebra of continous functions on the maximal ideal space and the complement problem concerns whether a nonsquare matrix in the algebra H^(R) can be augmented to become a unipotent matrix of the algebra. Wolff's proof of the corona theorem for the open unit disk D is given.

description: Phylogenetic analysis of DNA or other data commonly gives rise to a collection or sample of inferred evolutionary trees. Principal Components Analysis (PCA) cannot be applied directly to collections of trees since the space of evolutionary trees on a fixed set of taxa is not a vector space. This paper describes a novel geometrical approach to PCA in tree-space that constructs the first principal path in an analogous way to standard linear Euclidean PCA. Given a data set of phylogenetic trees, a geodesic principal path is sought that maximizes the variance of the data under a form of projection onto the path. Due to the high dimensionality of tree-space and the nonlinear nature of this problem, the computational complexity is potentially very high, so approximate optimization algorithms are used to search for the optimal path. Principal paths identified in this way reveal and quantify the main sources of variation in the original collection of trees in terms of both topology and branch lengths. The approach is illustrated by application to simulated sets of trees and to a set of gene trees from metazoan (animal) species.

description: This thesis extends the Job Demand-Control (Support) model by examining whether physical demands and health risks impact on the mental health of professional workers. It also examines whether men and women experience different amounts of physical demands and health risks and whether the impact on depression differs by gender. Survey data from 378 veterinarians were used. First, women report significantly more frequent experiences of improper posture and lifting, exposure to radiation and exposure to chemicals and gases as compared to men. Second, improper posture and lifting and risk of injury and illness have significant positive effects on depression for both women and men, whereas risk of injury and illness and exposure to radiation have significant gender-specific effects on female and male veterinarians’ depression. The findings of this study further our understanding of the impact of work experiences on professionals’ mental health.
Schooled in dreams : counter-posing "the ontology of ascent" with "auras of the other" to re-enchant in/vocation in sites of learning and being

description: This work is a multi-disciplinary conceptual inquiry into some of the historical structures and strictures of the ascetic-ascendant moral ontology that invariably conditions, and makes disparate, voice and vocation in educational spaces. Whereas the western philosophical tradition has become complicit with empiricism and supposed to do away with transcendence, the sublime remains, but has albeit lapsed into new programs of ascent with conspicuous devotion to new ‘fashions’ of asceticism (Weber’s work-promise analytic inflected ascetic-ascendant). Against all secular sensibility, the salvation effect (Nietzsche) has intensified (Gauchet). Instead of drawing ‘moral sources’ (Taylor) from the enchanted (Other), we imagine them in the immanent (Ontic); instead of destiny being subjective and relational, destinations are taken up instrumentally in what is more narrowly teleological. To the extent that moral sources shift immanent but are residually fantastic, I develop for reflective criticism the Dream Ontology: a work-promise matrix that circumscribes self-regard (identity) and world-engagement (morality) in alluring closures of meaning, whose tacit dislocating moral force initiates unsuspected agonistic effects. By profiling salient moral moments in the west, therefore, and attempting a genealogy of their cultural transmission, I explore how by means of the Dream Ontology the characteristic feature of modern life is fundamentally schismatic and self-buffering – cutting persons off from mythic sources, and affectivity more generally, in a barter to secure fanciful flourishing (promise) in the world. In remediation of this beguiling naturalization of disjoined voice and vocation, the Prophetic Mode will re/member being by sourcing transcendence (enchantment) in the Other, who ‘as’ sub-verse and ‘by means of’ solicitous counter-speech, affectively disrupts the dominion of dreams that reign thick in the text/ures of western schooling.

description: We systematically study the spectrum of excitations and the one-loop determinant of holographic Wilson loop operators in antisymmetric representations of $\mathcal{N}=4$ supersymmetric Yang-Mills theory. Holographically, these operators are described by D5-branes carrying electric flux and wrapping an $S^4 \subset S^5$ in the $AdS_5\times S^5$ bulk background. We derive the dynamics of both bosonic and fermionic excitations for such D5-branes. A particularly important configuration in this class is the D5-brane with $AdS_2\times S^4$ worldvolume and $k$ units of electric flux, which is dual to the circular Wilson loop in the totally antisymmetric representation of rank $k$. For this Wilson loop, we obtain the spectrum, show explicitly that it is supersymmetric and calculate the one-loop effective action using heat kernel techniques.

description: Background: Administrative data are used for disease surveillance and research. A validated case definition to study pediatric traumatic brain injury(TBI)using administrative data is not available. Methods: Using systematic review methodology, we identified studies validating TBI ICD coding. Second, a cohort of children with and without TBI from a pediatric emergency department (ER) was linked to administrative hospital and emergency databases. Nine ICD-10 based algorithms were tested. Sensitivity, specificity, and positive/negative predictive value (PPV, NPV) were calculated. Results: We identified three studies from the systematic review with varying diagnostic accuracy, and none were pediatric specific. The best algorithm to identify TBI cases was, “1 Hospital or 1 ER visit in 1 year”: sensitivity 69.8%, (67.3-72.2), specificity 96.7% (96.2-97.2), PPV 84.2% (82.0-86.3), NPV 92.7% (92.0-93.3). Conclusion: This study algorithm is best to capture ER or hospitalized TBI cases. Future research should develop algorithms which include children seen in the community.

description: Photospheric lines of B-type supergiants show variability in their profile shapes. In addition, their widths are much wider than can be accounted for purely by stellar rotation. This excess broadening is often referred to as macroturbulence. Both effects have been linked to stellar oscillations, but B supergiants have not been systematically searched yet for the presence of especially short-term variability caused by stellar pulsations. We have started an observational campaign to investigate the line profile variability of photospheric lines in a sample of Galactic B supergiants. These observations aim to improve our understanding of the physical effects acting in the atmospheres of evolved massive stars. We obtained four time-series of high-quality optical spectra for the Galactic B supergiant HD 202850. The spectral coverage of about 500 A around Halpha encompasses the Si II (6347 A, 6371 A), and the He I (6678 A) photospheric lines. The line profiles were analysed by means of the moment method. The time-series of the photospheric Si II and He I lines display a simultaneous, periodic variability in their profile shapes. Proper analysis revealed a period of 1.59 h in all three lines. This period is found to be stable with time over the observed span of 19 months. This period is much shorter than the rotation period of the star and might be ascribed to stellar oscillations. Since the star seems to fall outside the currently known pulsational instability domains, the nature of the discovered oscillation remains unclear.

description: There are government created organizations with a mandate to affect the sub- national system of innovation. These ‘innovation agency’ organizations provide functionality that enables additional innovation activity; this functionality may be delivered by organizations external to the innovation agency. The Alberta Oil Sands Science and Research Authority (AOSTRA), Alberta Heritage Foundation for Medical Research (AHFMR), and the Alberta Informatics Circle of Research Excellence (iCORE) are three innovation agencies that exemplify significant innovation policy investments by the Alberta government. This thesis uses historical analysis and case studies to examine these three innovation agencies. The historical analysis examines Alberta’s complex coevolution of institutions, policy leadership and technically challenging natural resources that set the stage for these innovation agencies to emerge. Case study techniques are used to explore the emergence, operations, and impact of the innovation agencies. The findings are then positioned in the system of innovation literature. It was found that the Alberta system of innovation was highly influenced by institutional control over natural resources and that the oil sands were particularly important, given their value and the scientific challenges that they presented. Peter Lougheed’s role in entrepreneurially shaping institutions was a contingency for the emergence of the cases. It was found that the innovation agencies generally acted to subsidize research activity in other organizations, although there were significant exceptions (e.g. AOSTRA’s IP policy and Underground Test Facilities). Finally, the instrumentality of the organizations was significant, leading to development and adoption of technological systems by industry and enhanced research capabilities at Alberta universities.
Spectropolarimetry of C-class flare footpoints

description: We investigate the decay phase of a C-class flare in full-Stokes imaging spectropolarimetry with quasi-simultaneous measurements in the photosphere (6302.5 A line) and in the chromosphere (8542 A line) with the IBIS instrument. We analyze data from two fields-of-view, each spanning about 40" \times 80" and targeting the two footpoints of the flare. A region of interest is identified from V/I images: a patch of opposite polarity in the smaller sunspot's penumbra. We find unusual flows in this patch at photospheric levels: a Doppler shift of -4 km/s, but also a possible radial inflow into the sunspot of 4 km/s. Such patches seem to be common during flares, but only high-resolution observations allowed us to see the inflow, which may be related to future flares observed in this region. Chromospheric images show variable overlying emission and flows and unusual Stokes profiles. We also investigate the irregular penumbra, whose formation may be blocked by the opposite polarity patch and flux emergence. The 40 min temporal evolution depicts the larger of the flare ribbons becoming fainter and changing its shape. Measurable photospheric magnetic fields remain constant and we do not detect flare energy transport down from the chromosphere. We find no clear indications of impact polarization in the 8542 A line. We cannot exclude the possibility of impact polarization, because weaker signals may be buried in the prominent Zeeman signatures or it may have been present earlier during the flare.
