description: We argue that conservation laws based on the local matter-only stress-energy-momentum tensor (characterized by energy and momentum per unit volume) cannot adequately explain a wide variety of even very simple physical phenomena because they fail to properly account for gravitational effects. We construct a general quasi}local conservation law based on the Brown and York total (matter plus gravity) stress-energy-momentum tensor (characterized by energy and momentum per unit area), and argue that it does properly account for gravitational effects. As a simple example of the explanatory power of this quasilocal approach, consider that, when we accelerate toward a freely-floating massive object, the kinetic energy of that object increases (relative to our frame). But how, exactly, does the object acquire this increasing kinetic energy? Using the energy form of our quasilocal conservation law, we can see precisely the actual mechanism by which the kinetic energy increases: It is due to a bona fide gravitational energy flux that is exactly analogous to the electromagnetic Poynting flux, and involves the general relativistic effect of frame dragging caused by the object's motion relative to us.

description: Millisecond pulsars (MSPs) have been studied in detail since their discovery in 1982. The integrated pulse profiles of MSPs appear to be stable, which enables precision monitoring of the pulse times of arrival (TOAs). However, for individual pulses the shape and arrival phase can vary dramatically, which is known as pulse jitter. In this paper, we investigate the stability of integrated pulse profiles for 5 MSPs, and estimate the amount of jitter for PSR J0437-4715. We do not detect intrinsic profile shape variation based on integration times from ~10 to ~100 s with the provided instrumental sensitivity. For PSR J0437-4715 we calculate the jitter parameter to be f_J=0.067+-0.002, and demonstrate that the result is not significantly affected by instrumental TOA uncertainties. Jitter noise is also found to be independent of observing frequency and bandwidth around 1.4 GHz on frequency scales of <100 MHz, which supports the idea that pulses within narrow frequency scale are equally jittered. In addition, we point out that pulse jitter would limit TOA calculation for the timing observations with future telescopes like the Square Kilometre Array and the Five hundred metre Aperture Spherical Telescope. A quantitative understanding of pulse profile stability and the contribution of jitter would enable improved TOA calculations, which are essential for the ongoing endeavours in pulsar timing, such as the detection of the stochastic gravitational wave background.

description: The dynamics of partons, hadrons and strings in relativistic nucleus-nucleus collisions is analyzed within the novel Parton-Hadron-String Dynamics (PHSD) transport approach, which is based on a dynamical quasiparticle model for partons (DQPM) matched to reproduce recent lattice-QCD results - including the partonic equation of state - in thermodynamic equilibrium. The transition from partonic to hadronic degrees of freedom is described by covariant transition rates for the fusion of quark-antiquark pairs or three quarks (antiquarks), respectively, obeying flavor current-conservation, color neutrality as well as energy-momentum conservation. The PHSD approach is applied to nucleus-nucleus collisions from low SIS to RHIC energies. The traces of partonic interactions are found in particular in the elliptic flow of hadrons as well as in their transverse mass spectra.

Planning and implementing solutions for artisanal gold mining sites, preventing environmental impacts and rehabilitating degraded areas : a Brazilian case study
Creators: name: Sousa, Rodolfo Neiva De
Publisher: name: University of British Columbia
Year: 2010

description: Artisanal small scale gold mining (ASGM) is a large source of environmental, health and safety problems in more than 70 developing countries, employing more than 15 million people, motivated by the current high price of gold and lack of better economic opportunities. Around 200,000 miners are located in Brazil with 40,000 concentrated in the Tapajos River Basin, in the Amazon. In this region, they extract gold by using rudimentary processes, causing mercury contamination, river siltation and deforestation. This thesis conducted research in the Tapajós region highlighting the strengths of some initiatives introduced by the GEF/UNDP/UNIDO Global Mercury Project from 2002 to 2008. Its training program was delivered to 4,200 artisanal miners in 141 mining sites, and it focused on disseminating 20 good mining practices. Performance indicators have shown that the conformance to standards before and after the program improved from 22 to 51%, with highest success on reduction of mercury (43%) and river siltation (37%), and improvement of sanitation (40%) in the participating sites. This study suggests the use of a heuristic approach to environmental impact assessment and ways to address those variables in intervention programs through training and education. The study also presents a successful rehabilitation initiative using simple local materials. In the participating sites 128 pits were backfilled after training and some of them revegetated. In another case study, a pilot plant to pre-concentrate gold with centrifuge followed by intensive cyanidation of the concentrate in a ball mill has demonstrated to be a fast and advantageous alternative to replace the current 20-day vat leaching or even amalgamation. This pilot study reduced cyanide consumption more than 20 times and may represent an economy of US$150,000/a in NaCN. Finally, this study analyzes 20 Brazilian regulations that affect ASGM, shows that many of them have not been effective, and suggests recommendations that would help to organize the miners and give them proper access to training, technical assistance and technology.

description: Multi-longitudinal-mode lasers have been believed to be good candidates as pump sources for optical frequency conversion. However, we present a semi-classical model for frequency conversion of optical signals with a multimode pump laser, which shows that fluctuations of the instantaneous pump power limit the conversion efficiency. In an experiment, we upconverted a 1550 nm optical signal in a periodically poled lithium niobate waveguide using with a multi-longitudinal-mode laser, an observed a maximum conversion efficiency of 70%, in good agreement with our theoretical model. Compared to single-mode pumping, multimode pumping is not a suitable technique for attaining stable near-unity-efficiency frequency conversion. However, the results obtained here could find application in characterization of the spectral or temporal structure of multi-longitudinal-mode lasers.

Subjects: subject: Geotechnology
subject: Geomatics

description: GNSS civil jammers are small portable sets capable of broadcasting disruptive signals in the GNSS bands. In this research, the effects of different civil jammers on GPS receivers are investigated and some techniques for detection, characterization and mitigation are proposed. Firstly, the presence of jammer signals is investigated. The detection techniques are categorized into power content analysis, power spectral density techniques and normality analysis. After detecting the jammer signal, there is a need to characterize the hostile signal parameters. Herein, different methods are considered which are classified into linear, bilinear and adaptive time-frequency representation methods. Following this, by using the estimated features of the interference signal, a clean version of the received signal is extracted. The output of this section is used as an input to the receiver. The performances of the proposed methods are assessed with different metrics including Carrier-to-Noise spectral density (C/N0) and frequency and phase lock indicator.
Select Issues in Applied Regulatory Theory

description: This dissertation comprises three chapters covering two topics in the area of applied regulatory theory. The first topic relates to the behavior of a firm subject to rate of return regulation while the second relates to bargaining outcomes in a theoretical model which can be applied to a negotiated settlements setting. In chapter 2 I present an empirical exercise showing evidence of a relationship between the shape of the yield curve and the composition of firms' capital structure with respect to durability. The results from chapter 2 are not specific to regulated industries; however, I use these results to inform a theoretical model of firm behavior, specific to firms subject to rate of return regulation. This model is developed in chapter 3. The modeled firm has access to multiple types of capital which are substitutes (imperfect or perfect) in production. These capital inputs are differentiated based on durability and heterogeneous marginal effects on the firm's total cost of capital. The results indicate that a regulated firm (relative to an unregulated firm) will over- or under-invest in specific assets depending on their durability and the size of the assets' marginal effects on the cost of capital relative to the regulated rate of return. In chapter 4 I present a bilateral bargaining model constructed to investigate the potential realization and distribution of bargaining quasi-rents. The results indicate that the realization of any quasi-rents requires the first mover have a sufficiently low proposal cost and that such rents are always captured by the first mover. Unlike most Rubinstein (1982) style bargaining games, the realized equilibrium may not be efficient in this game. As with the results of chapter 2, the results in chapter 4 are not constrained in application to regulated industries but do have specific relevance for the emergence of negotiated settlements wherein regulators facilitate bilateral bargaining as an alternative to traditional prescriptive regulation.
Development of Oxygen Electrodes for Reversible Solid Oxide Fuel Cells

description: The primary focus of this thesis has been to develop high performance stable oxygen electrodes, with a primary emphasis on a mixed conducting La0.3Ca0.7Cr0.3Fe0.7O3-δ (LCFCr) perovskite, for use in advanced reversible solid oxide fuel cells (RSOFCs). RSOFCs are single unit electrochemical devices that can operate in both the fuel cell (SOFC) and electrolysis (SOEC) mode, thus acting as flexible and efficient energy conversion systems. The interest in LCFCr arose from earlier work with LSFCr (La0.3Sr0.7Cr0.3Fe0.7O3-δ), shown to be a very promising SOFC cathode. Thus, this thesis began with a rigorous study of the oxygen evolution (OER) and reduction (ORR) reactions at the LSFCr material, including understanding how to interpret the electrochemical results. However, LSFCr has a thermal expansion coefficient (TEC) that does not match with common solid electrolytes and thus its long time stability is questionable. For this reason, the Ca analogue (LCFCr), a new electrode material, was synthesized and shown to have a much more suitable TEC. Extensive 2-electrode and 3-electrode half-cell studies revealed two slow steps during the OER and ORR, including oxygen/LCFCr surface reactions and O2- transfer at the LCFCr/electrolyte interface. It was also shown that LCFCr is more active in the electrolysis mode (OER) than in the SOFC mode (ORR). Further, the infiltration of ceria or co-infiltration of ceria+LCFCr led to substantial improvements in LCFCr performance, also providing further insights into the processes that control the reaction rates. It was shown that, after 200 h of operation in either the SOFC or SOEC modes, the main source of degradation was from the series resistance (the LCFCr/Au current collector interface), suggestive of Au sintering. The low frequency process, related to the LCFCr/air interface, also deteriorated somewhat, while the underlying LCFCr/electrolyte interface remained stable. This was confirmed from both electrochemistry and high-resolution TEM, showing the retention of a very high quality interface at the atomic level. A novel and very promising SOC powder and cell sintering methodology was also developed using microwave technology, significantly lowering the manufacturing temperature, processing, and energy requirements, due also to the much lower energy demand of the MW furnace. This translates to significant manufacturing cost savings, making MW processing of complete solid oxide cells a promising route for the future.

description: Solution of the Cox-Thompson inverse scattering problem at fixed energy [1,2,3] is reformulated resulting in semi-analytic equations. The new set of equations for the normalization constants and the nonphysical (shifted) angular momenta are free of matrix inversion operations. This simplification is a result of treating only the input phase shifts of partial waves of a given parity. Therefore, the proposed method can be applied for identical particle scattering of the bosonic type (or for certain cases of identical fermionic scattering). The new formulae are expected to be numerically more efficient than the previous ones. Based on the semi-analytic equations an approximate method is proposed for the generic inverse scattering problem, when partial waves of arbitrary parity are considered.

Toward an Understanding of Global-Mindedness: Perceptions and Engagement of Faculty of Internationalization in a Post-Secondary Institution

description: Internationalization has become central to many post-secondary institutions. Strategies around internationalization tend to focus on recruiting international learners, developing partnerships, and expanding study abroad programs. Less attention has been paid to components, such as teaching practices, that can often be Eurocentric in their worldview. With changing demographics, and the desire of many post-secondary institutions to recruit more international learners to campuses, it is necessary to structure internationalization in a way that is ethical and promotes the engagement of faculty in order to create a globally-minded teaching and learning environment. Faculty engagement has been identified as an essential enabler for successful internationalization, yet their perceptions of internationalization and global-mindedness are not well documented. This single case study investigated the perceptions faculty have of internationalization and global-mindedness, and how these views influence their teaching practice and engagement in internationalization. The study was composed of 16 faculty from one post-secondary institution in Alberta. The data collection methods of one-on-one interviews, journaling and focus groups were used. The data were coded and organized into the topics of perceptions of internationalization, perceptions of global-mindedness, the role of faculty in internationalization, fostering global-mindedness in teaching practice and institutional readiness. This research revealed that faculty are not considering their role within a diverse classroom. The research also revealed that the institution has done little to provide direction to faculty either through institutional messaging, or training and support. This has left faculty to decide what they will, or will not, do. The lack of institutional direction is a barrier and is leading to frustration with, and resentment of, international learners by faculty. Recommendations are offered for institutional leadership, faculty and for further research possibilities. Given that the institution has a plan to recruit more international learners, the recommendations should be considered in order to ensure that both the institution and faculty are prepared for the opportunities and challenges internationalization will present.

description: The Co-Generation heating system at Southland Leisure Centre (SLC) uses solar energy and natural gas to provide the necessary hot water supply for the swimming pools. This is one of the largest solar heating systems in Alberta. The system was modeled using TRNSYS software and its components to represent the various parts of the solar heating system. Experimental data from a previous project was simulated and used to assess the accuracy of the modeling. After the model was set-up and validated, the software was used to simulate the current SLC heat management system. The model was also used to investigate several possible system improvements. A number of operational and maintenance concerns have been identified, including lack of verification of current quality of glycol, overheating of the water-glycol mixture and data loss from the SLC building management system. Recommendations to improve system performance, include changing the temperature setting for when the system turns ‘on’, increasing the amount of energy the system can store and turning on the make-up water feed at the ideal times. The SLC solar heating system was found to not be financially beneficial under current energy prices. Future projects should ensure constant heat demand to maximize productivity. Analysis of the solar heating system at SLC provides important information to help future projects become more competitive.
The Interrogation of Traumatic Brain Injury with MR Spectroscopy and Molecular Imaging

description: Metabolic perturbations in early acute severe traumatic brain injury (TBI) using magnetic resonance (MR) spectroscopy, and the prospects of molecular imaging of repetitive mild TBI, form the driving principles of this thesis work. Brain metabolism is thought to be maintained by neuronal-glial metabolic coupling, whereby glia take up glutamate from the synaptic cleft for conversion into glutamine, triggering glial glycolysis and lactate production. This lactate is shuttled into neurons and further metabolized. Using a weight drop model of severe TBI and MR spectroscopy with infusion of 13C labeled glucose, lactate and acetate, this portion of the thesis investigated the hypothesis that neuronal-glial metabolism is uncoupled following severe TBI. High resolution MR spectroscopy revealed significant labeling of lactate irrespective of the infused substrate and decreased labelling of other metabolites. Histopathology, while showing features of severe brain injury, also stained positive for tau. A microtubule associated protein, tau has been shown to accumulate in brains following TBI, particularly those related to sports and combat. It was further hypothesized that tau could be visualized through the administration of a unique anti-tau single domain antibody (sdAb)-nanoparticle complex. Through llama immunization, tau specific sdAbs were isolated, panned and characterized for bioconjugation to MR sensitive NaDyF4-NaGdF4 nanoparticles, towards non-invasive imaging of tau in vivo. At a ratio of ~4 sdAbs per nanoparticle, the complex was able to cross the neuronal membrane and bind to intracellular tau in live hippocampal neuronal cultures. Preliminary in vivo studies, establishing the model for repetitive mild TBI showed considerable tau staining within the entorhinal cortex, dentate gyrus and hippocampal CA3 sector sparing CA1. While there were some T1 changes in MR imaging, clinical translation will require further tests for sdAb – nanoparticle affinity to both tau and hyperphosphorylated tau, optimal dosage and safety, toxicology and clearance profile. It may be concluded that the early increase in brain lactate or lactate storm marks severe TBI; and tau abnormality and associated disrupted axonal transport, may be the hallmark of repetitive mild TBI, making it a potential MR visible biomarker for TBI. These concepts may guide future diagnostic and therapeutic directions.

description: Solvent-assisted process is promising to recovery Canada's bitumen recourses, but the prediction techniques for the solubility, density and viscosity of bitumen and solvent mixtures in reservoir simulation are not well developed. This thesis works to develop the application methodology of the simplified Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) to bitumen and solvent mixtures. New binary interaction coefficient correlation and bitumen characterization method are developed to model the solubility, density and viscosity of such mixtures. These results are also integrated into the reservoir simulation of solvent-assisted recovery. Using the developed method, the average absolute relative deviations (AARDs) are 6.6% for the solubility, 2.3% for the density and 14.6% for the viscosity. In addition, the reservoir simulation results indicate good agreement with the sandpack production data using solvents. This thesis has developed the methodology to model the phase behavior and recovery process of bitumen and solvent using PC-SAFT.
Experiences of women diagnosed with HIV in the Downtown Eastside

description: This paper examines experiences of five women diagnosed with HIV in the Downtown Eastside. Women living with HIV in this community experience multiple intersecting oppressions based on gender, class and ethnicity as well as stigma related to their HIV status and association with marginalized groups such as drug users and sex workers. Using narrative methodology this paper explores several areas relating to women diagnosed with HIV including themes of “life is over”, “stigma management”, “disconnecting from self and others”, “reconnecting with support systems” and “giving and sharing experiences”. The findings suggest that while women living with HIV in the Downtown Eastside face multiple barriers particularly when first diagnosed they are also able to engage with health and social supports and contribute to the lives of others and their community in a meaningful way.

description: The anisotropic electronic structure responsible for the antiferromagnetic transition in CeRu$_2$Al$_{10}$ at the unusually high temperature of $T_0$ = 28 K was studied using optical conductivity spectra, Ce 3d X-ray photoemission spectra, and band calculation. It was found that the electronic structure in the $ac$ plane is that of a Kondo semiconductor, whereas that along the b axis has a nesting below 32 K (slightly higher than $T_0$). These characteristics are the same as those of CeOs$_2$Al$_{10}$ [S. Kimura {\it et al.}, Phys. Rev. Lett. 106, 056404 (2011).]. The $c$-$f$ hybridization intensities between the conduction and $4f$ electrons of CeRu$_2$Al$_{10}$ and CeOs$_2$Al$_{10}$ are weaker than that of CeFe$_2$Al$_{10}$, showing no magnetic ordering. These results suggest that the electronic structure with one-dimensional weak $c$-$f$ hybridization along the b axis combined with two-dimensional strong hybridization in the $ac$ plane causes charge-density wave (CDW) instability, and the CDW state then induces magnetic ordering.

Effects of IFRS on Accounting Quality and Tax Aggressiveness: Evidence from Canadian Mandatory Adoption

description: This study investigates the effects of mandatory adoption of the International Financial Reporting Standards (IFRS) on accounting quality and tax aggressiveness. Accounting quality is epitomized as the combined relevance and reliability of the reported financial information to investors (value relevance), and the faithfulness with which firms report those numbers (financial reporting aggressiveness). The tax aggressiveness component presents an original work on the effects of IFRS adoption by using unique Canadian data to assess IFRS as a determinant of tax aggressiveness. The study draws from the disclosure and bounded rationality theories to explain the effects of the new standard. I argue that if the additional disclosures required under IFRS are specific and useful, then they must increase value relevance, consistent with the disclosure theory and the findings in Sabac, Scott and Wier (2005). Based on the logic of the bounded rationality theory, I also argue that firms will satisfice economic self-interest in their financial and tax reporting due to constraints. My study uses difference-in-differences techniques following prior studies, and employs multi-models, including models of Ohlson (1995) and Balachandran and Mohanram (2011) for value relevance; Barth, Landsman and Lang (2008) and Ahmed, Neel and Wang (2013) for financial reporting aggressiveness; and modified Hoopes, Mescall, and Pittman (2012) model for tax aggressiveness. This study finds that value relevance and financial reporting aggressiveness increased for the IFRS adopters in post-adoption period consistent with the disclosure and the bounded rationality theories. These findings suggest that mandatory IFRS adoption has both positive and negative effects on accounting quality. The study fails to find evidence of increase in corporate tax aggressiveness. I argue that the likelihood of audit and potentially high penalties for tax non-compliance constrained the ability of firms to engage in tax aggressiveness after adopting IFRS, in line with the logic of the bounded rationality theory. Contrary to the concerns by the tax authority, corporate tax aggressiveness did not increase for firms that mandatorily adopted IFRS in Canada. Finally, the theories of disclosure and bounded rationality explain the effects of mandatory IFRS adoption on accounting quality and tax aggressiveness.

Evidence that the Bursting Component of the X-ray Radiation From 3C 111 Originates in the PC-Scale Jet

description: Evidence is presented indicating that the bursting component of the X-ray radiation detected in the nuclear region of the active radio galaxy 3C 111 comes from the blobs ejected in the pc-scale jet and not from the accretion disc. After each new outburst the radio flux density associated with it increases to a peak in ~1 year and then subsides over a period of 1-2 years with the flux falling off exponentially as the blob moves outward and dissipates. Similar peaks (bursts) are seen in the X-ray light curve and a cross-correlation between the two shows a very high correlation with the X-ray peaks leading the radio peaks by ~100 days. A second cross-correlation, this time between the radio event start times and the X-ray light curve, also shows a significant correlation. When this is taken together with the long (~1 yr) delay between the start of each ejection event and its associated X-ray peak it indicates that this bursting component of the X-ray flux must be associated with the ejected blobs in the pc-scale jet and not with the accretion disc. Because X-ray telescopes do not have the resolution required to resolve the accretion disc area from the pc-scale jet, this paper is the first to present observational evidence that can pinpoint the point of origin of at least those long-timescale X-ray bursts with durations of 1-3 yrs.

description: Peripheral nerve injury is a prevalent condition, afflicting millions of patients around the world and costing the healthcare system billions of dollars. It can lead to sensory loss and debilitating pain, and has a wide range of causes including trauma, infectious diseases, and diabetes. Although peripheral nerves have some inherent ability to regenerate, the recovery process is slow and complex, and regenerative outcomes are limited. However, electrical stimulation has been shown to accelerate recovery. In this work, uniform electric fields are explored in their capacity to encourage neurite outgrowth. A novel microelectrode array is designed to generate uniform fields for application to neurons in vitro, using snail and rat models. In parallel, an implantable nerve cuff was created to apply similar fields in vivo, in injured rat sciatic nerve models. Uniform electric field application was shown to increase overall neuritic outgrowth in snail neurons in vitro.

For those accused of this crime, or who actually committed it, it meant exclusion from society. For the urban Castilian elites this struggle was a way of justifying themselves as a governing group. Defence of society against sodomites is related to the political context and to the internal struggles of the urban elites. In the lawsuits analysed, there is clear repetition of a series of words related to individual reputation and social esteem: fama, honour, Buena fama, fama publica, infamia. These can be shown to be vital to the defence of the accused, and also frequently recur in the legislation itself. Rumour was also used as propaganda to shape public opinion and to discredit rivals in the struggle for urban power.

description: The Indian Coherent Neutrino-nucleus Scattering Experiment(ICNSE) has been proposed at Bhabha Atomic Research Centre in India to measure the coherent elastic neutrino-nucleus scattering process using electron antineutrinos produced from reactors. Phenomenological studies are performed to find out the sensitivity of a sapphire detector for various fundamental physics parameters at an exposure of one year. Reactors of different core compositions, sizes, and thermal powers have been considered as sources of electron antineutrinos. The potential of the ICNSE to measure the weak mixing angle at a low energy regime has been extracted. Furthermore, the detector's capability has been investigated for examining the electromagnetic properties of neutrinos, including their magnetic moment. Additionally, an exploration has been conducted on the detector's sensitivity in restricting new interactions between neutrinos and electrons or nuclei, thereby constraining the parameter space related to light mediators. It is found that the ICNSE detector can put a stronger constraints on the scalar and vector mediators masses.

description: In this dissertation, I explore the reach of the Evolutionary Contingency Thesis—a view that emphasizes the role of dependency relations and chance in evolution (Gould 1989, Beatty 2006a). Contingency produces diverse biological entities, processes, and mechanisms. I analyze the implications of evolution’s contingency in three areas. First, I address the problem of evolutionary individuality, which concerns the nature of entities that selection acts on (Godfrey-Smith 2009, Ereshefsky and Pedroso 2015). If we accept Lewontin’s 1970 view that individuals are selected, then what exactly are these individuals? I argue that evolutionary contingency and its diversity of outcomes causes a plurality of individuality types. These types of individuals emerge, evolve, and disappear through evolution. Second, I defend a disunified model of major transitions in evolution. Major transitions mark pivotal turning points in life’s history, such as the transition from unicellularity to multicellularity. Philosophers and biologists aim to unify evolution’s transitions by establishing a property all major events share. I argue that evolutionary contingency’s emphasis on diversity supports a disunified model of transitions. That is, we should expect numerous kinds of major transitions given the diverse sets of outcomes caused by evolutionary contingency. Finally, I extend the contingency analysis to a topic in philosophy of medicine: The nature of cancer. It is common to view cancer as a by-product of our evolution as multicelled creatures (Germain 2012, Aktipis et al. 2015). However, Lean and Plutynski (2016) argue that cancer is also a direct product of evolution by selection. In both cases, cancer is characterized in terms of how it functions (or does not function) as an object of selection. I argue that the diversity among cancers suggests philosophers should shift their focus to cancers’ structural differences rather than only their functional similarities.
The role of super-asymptotic giant branch ejecta in the abundance patterns of multiple populations in globular clusters

description: In order to account for the chemical composition of a stellar second generation (SG), Globular Clusters (GCs) evolution models based on the asymptotic giant branch (AGB) scenario so far included only the yields available for the massive AGB stars, while the possible role of super-AGB ejecta was either extrapolated or not considered. In this work, we explore the role of super-AGB ejecta using yields recently calculated by Ventura and D'Antona. Models of clusters showing extended Na-O anticorrelations, like NGC 2808, indicate that a SG formation history similar to that outlined in our previous work is required: formation of an Extreme population with very large helium content from the pure ejecta of super-AGB stars, followed by formation of an Intermediate population by dilution of stellar ejecta with pristine gas. The very O-poor Na-rich Extreme stars can be accounted for once deep-mixing is assumed in SG giants forming in a gas with helium abundance Y> 0.34, which significantly reduces the atmospheric oxygen content, while preserving the sodium abundance. On the other hand, for clusters showing a mild O-Na anticorrelation, like M 4, the use of the new yields broadens the range of SG formation routes leading to abundance patterns consistent with observations. It is shown that models in which SG stars form only from super-AGB ejecta promptly diluted with pristine gas can reproduce the observations. We discuss the variety of small helium variations occurring in this model and its relevance for the horizontal branch morphology. In some of these models the duration of the SG formation episode can be as short as \sim10 Myr; the formation time of the SG is thus compatible with the survival of a cooling flow in the GC, previous to the explosion of the SG core collapse supernovae. We also explore models with formation of multiple populations in individual bursts, each lasting no longer than \sim10 Myr.

Vancouver's living wage campaign : social movement unionism and identity construction
Creators: name: Ptashnick, Melita Blanche
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents the findings of research on a living wage campaign conducted by low-wage hospital support workers. First, I conducted an analysis with a mobilization theory framework to assess whether a campaign strategy that utilizes the extended set of collective action frames associated with social movement unionism can compensate for the effects of severe economic environmental conditions on labour bargaining power. Second, as identity narratives have important consequences for social movement mobilization, I assessed how story modes shape identity assertion and alliance building within a social movement unionism organizing model. Based on findings from interviews with the outsourced workers, I recommend modifications to mobilization theory because within a social movement unionism model, campaign success depends, in part, on workers actively shaping the interpretive framework, and on social cohesion within the union’s horizontal network. While a depressed economic environment may dampen the power of interpretive framework resonance and social cohesion to achieve economic success from a campaign, successes in worker empowerment and skills can still be achieved. It is worthwhile to continue social movement strategies through a poor economic period to maximize the economic gains that are possible under the conditions as well as to empower and train workers into activists, and to organize horizontal networks, thus laying the groundwork for social movement expansion and success, when economic conditions improve. In addition, the findings reveal that the worker activists presented associational declarations of their alliances and atrocity tales of their hardships as their favoured motivational tools for mobilization. In their atrocity tales of hardship, activists asserted value-based identities to encourage mobilization, while associational declarations indicated that in order to build alliances activists selected an identity to emphasize their similarity to a given potential ally. These findings indicate that the basis for identity construction and assertion to encourage micromobilization is contingent on the type of social movement organizing model, alignment of activist and public values, and the nature of the ally audience.
The Effects of Time and Space on Developing Lifelong Learners in One Short-Term Travel Study Program

description: Short term travel study programs of six weeks or less are the fastest growing study abroad programs in Canada but the least researched. The research that does exist offers little in the way of understanding how the role of the compression of time and the expansion of space, two characteristics of the shorter term programs, affect student learning. This dissertation is a qualitative interpretive case study exploring the unique learning that took place in one University of Calgary short term program, 2011 Food Culture in Spain. Through one to one open ended interviews with 12 participants, focus groups with those same participants, document analysis, key informant interviews and a personal observation journal, my research concludes that the emphasis on group dynamics affects the way students see themselves as learners. In this particular short term program interpersonal culture shock as a form of disjuncture encouraged students to see themselves as lifelong learners in a complex and globalized world. The results from this case study can help educators understand how emotional and holistic learning can help develop lifelong learning characteristics amongst 21st century post-secondary undergraduates.
