Nature and grief : an ecocritical analysis of grief in children's literature
Creators: name: Lankford, Megan
Publisher: name: University of British Columbia
Year: 2010

description: This study explores the role of nature in three picture books that broach the topics of death, grief, depression, or loss: Bryan Mellonie and Robert Ingpen’s Lifetimes, Shaun Tan’s The Red Tree, and Roni Schotter and Kimberly Bulcken Root’s In the Piney Woods. Using a close reading of both the text and the visual images, these picture books are analyzed for their use of nature in discussing the concepts of death, regeneration, life, and the life cycle. The three texts reflect two primary historical trends of ecocriticism that of nature-as-space and nature-as-knowledge as exemplified by writers in the Romantic era, the American pastoral, and the Victorian period. Through a further examination of the text and image relationship within the text, the texts are then analyzed for their effectiveness and accessibility to children within the practice of bibliotherapy.

description: An important goal in elementary mathematics classrooms is for teachers to employ instructional practices that engage students to develop sustainable and deep conceptual mathematics understanding. In preservice education, this often requires transforming student teachers’ beliefs about teaching mathematics, and their knowledge of mathematics content and pedagogy. This study involved preservice teachers from two mathematics methods courses and specifically examined teaching and learning experiences that contributed to their development in: 1) content knowledge, 2) teacher efficacy, and 3) pedagogy. Building capacity across these three constructs was considered significant in the preservice mathematics courses. This research focused on identifying the factors which influenced students’ development in these three constructs with the view to enhance preservice mathematics programs. The theoretical framework for this research was underpinned by several theories: mathematical knowledge for teaching theory, self-efficacy theory, constructivist learning theory, and adult learning theory. These selected theories were deemed to be highly pertinent to the phenomena of preservice mathematics teacher development and drew upon a range of theorists such as: Ball, Thames, and Phelps, 2008; Bandura, 1986; Dewey, 1938; Knowles, 1984; Mezirow, 1991; Piaget, 1952; and Vygotsky, 1978. Through a mixed methods approach, this study utilized quantitative data related to student teachers’ mathematics content knowledge, teacher efficacy, and anxiety. The qualitative data included student teachers’ journals, interviews, and the researcher-instructor’s journals. The five broad themes that emerged from the converged data were: 1) importance of the instructor’s role in mathematics teacher development; 2) problem solving to support conceptual understanding; 3) building confidence as a mathematics teacher; 4) working towards constructivist pedagogy; and 5) classroom management. Two models were developed from the findings in this study. Model one highlights the differentiating mathematics needs of preservice teachers and ways to support their needs prior to the start of their teacher education program; and model two addresses conceptualizations of coherence and how this can be achieved across the dimensions of mathematics preservice education. These models and this study’s significant findings will be of interest to those seeking to enhance preservice elementary mathematics teacher education through building coherence and implementing strategies to meet the varying backgrounds of student teachers.

description: We aim to constrain the geometrical extent of the chromosphere of non-binary K giant stars and detect any spatial structures in the chromosphere. We performed observations with the CHARA interferometer and the VEGA beam combiner at optical wavelengths. We observed seven non-binary K giant stars. We measured the ratio of the radii of the photosphere to the chromosphere using the interferometric measurements in the Halpha and the Ca II infrared triplet line cores. For beta Ceti, spectro-interferometric observations are compared to an non-local thermal equilibrium (NLTE) semi-empirical model atmosphere including a chromosphere. The NLTE computations provide line intensities and contribution functions that indicate the relative locations where the line cores are formed and can constrain the size of the limb-darkened disk of the stars with chromospheres. We measured the angular diameter of seven K giant stars and deduced their fundamental parameters: effective temperatures, radii, luminosities, and masses. We determined the geometrical extent of the chromosphere for four giant stars. The chromosphere extents obtained range between 16% to 47% of the stellar radius. The NLTE computations confirm that the Ca II/849 nm line core is deeper in the chromosphere of ? Cet than either of the Ca II/854 nm and Ca II/866 nm line cores. We present a modified version of a semi-empirical model atmosphere derived by fitting the Ca II triplet line cores of this star. In four of our targets, we also detect the signature of a differential signal showing the presence of asymmetries in the chromospheres. Conclusions. It is the first time that geometrical extents and structure in the chromospheres of non-binary K giant stars are determined by interferometry. These observations provide strong constrains on stellar atmosphere models.

description: A series of bidentate cyclometalated Ru(II) complexes of general formula [Ru(N^N)(N^N)(C^N)]+, where N^N = polypyridyl ligand and C^N = cyclometalating ligand, have been synthesized, characterized and tested in dye-sensitized solar cells (DSSCs). Cyclometalated Ru(II) complexes, in general, exhibited broader absorption profiles and cathodically shifted electrochemical potentials compared to their polypyridyl analogues. The prototypical cycloruthenated compound, [Ru(bpy)2(ppy)]+ (bpy = 2,2'-bipyridine; Hppy = 2-phenylpyridine), displayed comparable UV-vis spectral coverage to the standard DSSC dye, N3. Molar extinction coefficients were enhanced and the absorption profile was red-shifted through substitution of the molecular periphery. Molecules from the [Ru(bpy)2(ppy)]+ family displayed HOMO and excited-state energy levels properly aligned for use in the DSSC. Anchoring –CO2H groups were ideally located on the bidentate polypyridyl ligands (e.g., H2dcbpy; H2dcbpy = 4,4'-dicarboxy-2,2'-bipyridine) because this arrangement localized excited-state electron density proximate to TiO2. Increased molecular light absorption was accomplished by installing conjugated substituents (e.g., -NO2, -phenyl, -pyridyl, -2-thiophene-carbaldehyde) on the anionic ring of molecules with general formula [Ru(H2dcbpy)2(C^N)]+. Aromatic substituents were superior to –NO2 because of an ideally positioned lowest excited-state (i.e., localized to H2dcbpy instead of –NO2). Substitution of the anionic ring with 2-thiophene-5-carbaldehyde para to the Ru-C bond resulted in a superior absorption profile enabling a modest cell power conversion efficiency (PCE) of 3.3%. Replacement of one H2dcbpy ligand with bpy generated tris-heteroleptic cyclometalated Ru(II) dyes with general formula [Ru(H2dcbpy)(bpy)(C^N)]+. The use of electron-rich cyclometalating ligands, however, led to poor PCEs because of incompatible Ru electrochemical potentials for dye regeneration. Strong electron withdrawing groups (e.g., –CF3) were required on the C^N ligand to overcome this problem. The combination of electron-rich aromatic (e.g., thiophene, triarylamine) groups on the ancillary bpy and –CF3 groups on the C^N ligand enabled the best light-absorption properties of any dyes examined in this dissertation, while also maintaining properly aligned HOMO and excited-state energy levels for use in the DSSC. Power conversion efficiencies of 7.3% at 1 Sun were attained with these dyes, exceeding the 6.3% achieved by the paradigmatic N3 dye under the same conditions.

description: This paper present some indications of the existence of a Citation Advantage related to linked data, using astrophysics as a case. Using simple measures, I find that the Citation Advantage presently (at the least since 2009) amounts to papers with links to data receiving on the average 50% more citations per paper per year, than the papers without links to data. A similar study by other authors should a cummulative effect after several years amounting to 20%. Hence, a Data Sharing Citation Advantage seems inevitable.

description: This paper proposes SEFGAN, a Deep Neural Network (DNN) combining maximum likelihood training and Generative Adversarial Networks (GANs) for efficient speech enhancement (SE). For this, a DNN is trained to synthesize the enhanced speech conditioned on noisy speech using a Normalizing Flow (NF) as generator in a GAN framework. While the combination of likelihood models and GANs is not trivial, SEFGAN demonstrates that a hybrid adversarial and maximum likelihood training approach enables the model to maintain high quality audio generation and log-likelihood estimation. Our experiments indicate that this approach strongly outperforms the baseline NF-based model without introducing additional complexity to the enhancement network. A comparison using computational metrics and a listening experiment reveals that SEFGAN is competitive with other state-of-the-art models.

Year: 2013

description: Bacteria require efficient iron acquisition systems to infect and colonize the mammalian host. Neisseriaceae and Pasteurellaceae have developed an iron uptake system that involves iron removal from host glycoproteins. The human pathogen, Haemophilus influenzae, has a surface receptor complex containing transferrin binding proteins (TbpA and TbpB). This complex facilitates the release of iron from host transferrin and into the periplasm, where it binds to a periplasmic binding protein, ferric binding protein (FbpA). FbpA is part of the ABC transporter, FbpABC that transports iron from the periplasm into the cytoplasm. The interaction between FbpA and FbpBC is currently unknown. A series of site directed mutants were created to study this interaction based on models of other ABC transporters. We have developed a new novel reporter system to study this interaction. The results of this study have shown the lux reporter system to be more advantageous than past methods that evaluated iron uptake systems.

description: Measures of the impact of scientific research increasingly become tools for various administrative applications. Bibliometric measures of the impact of research typically rely on citation analyses, which may not be appropriately representing all areas of scholarship, e.g. Arts and humanities. Metrics alternative to citation analyses are referred to as altmetrics, and include parameters derived from usage data, e.g. the number of times a paper is downloaded. In this paper I consider usage data from the open full text repository hprints.org for Nordic arts and humanities, and on the basis of an analysis of a small dataset from hprints.org, suggest new altmetrics based on the normalized squared number of downloads that could prove to be a valuable tool to quantify the impact of research published in open full text repositories.

description: Methicillin-resistant Staphylococcus aureus (MRSA) is a highly virulent, multidrug –resistant pathogen responsible for the majority of soft tissue infections. The role of neutrophils in S. aureus soft tissue infections is currently unclear. The objective of this thesis was to characterize early neutrophil recruitment to a localized MRSA infection. Using spinning disk confocal microscopy, we developed a mouse model to visualize the behaviour of neutrophils in the skin following the introduction of an agarose bead embedded with GFP-expressing MRSA. We observed significant neutrophil recruitment not only in the venules but also in the capillaries, which we showed to be mediated by the β2 and α4 integrins. Blocking these integrins in mouse models increased capillary perfusion, reduced cell death at early time points, and altered lesion size during infection. Understanding the contribution of neutrophils in MRSA soft tissue infection will help to elucidate novel therapeutic targets in these infections.

We present results of our work in training convolutional neural networks for denoising seismic data, specifically attenuation of surface related multiples and removal of overlap of shot energies during simultaneous-shooting survey. The proposed methodology is being explored not only for its ability to minimize human involvement but also because of the trained filter's ability to accelerate the process, hence, reduce processing time.

Beyond service : looking at power in community service-learning relationships
Creators: name: Humphries, Charlotte
Publisher: name: University of British Columbia
Year: 2010

description: The research presented here is an analysis of power in the context of a community service-learning relationship. The theoretical community service-learning literature cautions that relationships in this context risk reproducing and reinforcing power inequities between community and the university. An analysis of this literature reveals that central narratives about power and relationships may not entirely reflect the reality of practice. The analysis of the literature also points to the unfulfilled need to more carefully consider the community within academic discourse and studies of community service-learning. Using a case study of the YWCA Vancouver and the UBC Learning Exchange relationship, this research explores the following questions: 1. How does power operate in the context of the YWCA-Learning Exchange community service-learning relationship? 2. How are power relations conceptualized by participants in this community service-learning relationship? 3. How do the results from this inquiry align with popular theoretical perspectives on community service-learning? The analysis of 13 in-depth interviews conducted with YWCA staff, UBC Learning Exchange staff, and students engaged in community service-learning activities with these two organizations reveals that actors in the YWCA-Learning Exchange relationship are aware of traditional power inequities between universities and communities. These actors actively reject traditional power relations and react negatively when they perceive a reproduction of these relations in the context of community service-learning. Results from the analysis of this unique case contribute to the community service-learning literature by adding new voices and complexity to the discourse. In contrast to the essentialist view of power that is proposed in the literature, power in this case is understood to operate along multiple dimensions. YWCA staff do not attribute different value to the types of service which the literature differentiates as charity or social justice. Finally, community staff do not identify as powerless in the relationship, and instead view themselves as integral to the operation and the success of community service-learning. Results point to a need for further research into the experiences of all actors in community service-learning with the aim of contributing to the discourses of power and relationships in this context.

description: We present new spectropolarimetric observations of the normal A-type star Vega, obtained during the summer of 2010 with NARVAL at Télescope Bernard Lyot (Pic du Midi Observatory). This new time-series is constituted of 615 spectra collected over 6 different nights. We use the Least-Square-Deconvolution technique to compute, from each spectrum, a mean line profile with a signal-to-noise ratio close to 20,000. After averaging all 615 polarized observations, we detect a circularly polarized Zeeman signature consistent in shape and amplitude with the signatures previously reported from our observations of 2008 and 2009. The surface magnetic geometry of the star, reconstructed using the technique of Zeeman-Doppler Imaging, agrees with the maps obtained in 2008 and 2009, showing that most recognizable features of the photospheric field of Vega are only weakly distorted by large-scale surface flows (differential rotation or meridional circulation).

description: The rapid evolution of the Smart-everything movement and Artificial Intelligence (AI) advancements have given rise to sophisticated cyber threats that traditional methods cannot counteract. Cyber threats are extremely critical in financial technology (FinTech) as a data-centric sector expected to provide 24/7 services. This paper introduces a novel and refined taxonomy of security threats in FinTech and conducts a comprehensive systematic review of defensive strategies. Through PRISMA methodology applied to 74 selected studies and topic modeling, we identified 11 central cyber threats, with 43 papers detailing them, and pinpointed 9 corresponding defense strategies, as covered in 31 papers. This in-depth analysis offers invaluable insights for stakeholders ranging from banks and enterprises to global governmental bodies, highlighting both the current challenges in FinTech and effective countermeasures, as well as directions for future research.
Characterizing the Relationship Between Energy Metabolism and Mesenchymal Stem Cell Therapy in the Infarcted Heart

description: Objective: A constant provision of adenosine triphosphate (ATP) is of necessity for cardiac contraction. If the heart progresses towards failure following a myocardial infarction (MI) it may undergo metabolic alterations that have the potential to compromise its ability to meet energetic demands. The main focus of this dissertation was to evaluate the efficacy of mesenchymal stem cell (MSC) transplantation to mitigate abnormalities in energy metabolism that contribute to ATP synthesis post-MI in the presence and absence of diet-induced insulin resistance. Methods: C57BL/6 mice were chow or high-fat fed prior to induction of a MI via chronic ligation of the left anterior descending coronary artery. Post-ligation, MSCs were transplanted via intramyocardial injection. Serial echocardiography was performed prior to and up to 28 days post-MI to evaluate cardiac systolic function. Hyperinsulinemic-euglycemic clamps coupled with the administration of isotopic tracers were employed post-MI to assess systemic insulin sensitivity and insulin-mediated, tissue-specific substrate uptake in the conscious, unrestrained mouse. High-resolution respirometry was utilized to evaluate cardiac mitochondrial function in saponinpermeabilized cardiac fibers. Western blotting was completed to assist in identifying molecular mechanisms through which the MSC therapy may modulate cardiac and systemic metabolic phenotypes. Results: The improved systolic performance in MSC-treated mice was associated with a lessening of non-pathological in vivo insulin-stimulated cardiac glucose uptake. The changes in glucose uptake may have been via the MSC-mediated alterations in fatty acid availability/utilization. MSC therapy preserved fatty acid uptake in the absence of diet-induced insulin resistance. Conversely, the cell-based treatment reduced circulating nonesterified fatty acid concentration in high-fat fed mice. Additionally, potential impairments in insulin signalling may have been minimized as indicated by conservation of the p-Akt/Akt ratio. Down-stream of glucose uptake, the administration of MSCs conferred protective effects to mitochondrial oxidative phosphorylation efficiency, maximal function and mitochondrial content. Conclusions: The experiments conducted in this dissertation provide insight into the utility of MSC transplantation as a metabolic therapy for the metabolic perturbations that characterize insulin resistance in the infarcted heart. Also, these studies propose potential mechanisms of action that lead to an enhanced energetic and functional state in the infarcted heart following MSC transplantation.

Exciting results are blooming, thanks to a convergence between unprecedented asteroseismic data obtained by the satellites CoRoT and Kepler, and state-of-the-art models of the internal structure of red giants and of galactic evolution. The pulsation properties now available for thousands of red giants promise to add valuable and independent constraints to current models of structure and evolution of our galaxy. Such a close connection between these domains opens a new very promising gate in our understanding of stars and galaxies. Scientists specialised in galactic evolution, in stellar structure, and in asteroseismology, gathered together in this workshop to discuss the current status and uncertainties involved in modelling the structure and evolution of red giants, as well as open questions regarding the study of stellar populations in the Milky Way.

Encounters with the Divine in the Hebrew Bible
Creators: name: Gellis, Elizabeth
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Other language, communication and culture not elsewhere classified

description: My dissertation demonstrates the Jewish tradition’s significance for rhetoric by analyzing Biblical ‎encounters with the divine—the ultimate Other. Thus, this dissertation responds to calls such as Steven B. Katz’s to continually redefine what ‎‎“rhetoric” means to us (“Hebrew Bible” 134). In the past several decades, there has been ‎increasing interest in rhetorics that challenge ‎our preconceived notions of what constitutes ‎‎“rhetoric,” both loosening the Greeks and Romans from a skewed reception history and calling ‎for definitions of rhetoric to move “beyond the Greeks” (Lipsom and Binkley). Both these ‎approaches highlight the need for a more diverse understanding of rhetoric—an understanding ‎that better foregrounds the import of the Other. The still-germinal field of Jewish rhetorics has ‎emerged as one response to these calls to diversify and decolonize the rhetorical tradition. As ‎such, this dissertation is also a reclamation of a Jewish tradition that has been—inadvertently ‎and explicitly—ignored, misunderstood, and suppressed.‎
 I argue that representations of divine ‎encounters in the Tanakh (Hebrew Bible) offer a rhetorical framework for encountering the ‎Other—human and divine—as holy. Neither appropriative nor obeisant, this framework offers a ‎uniquely Jewish perspective on encountering the Other—one that has not received adequate ‎academic attention. In a moment where the imperative to engage with Others is so pressing, I ‎address that call to action by bringing together a breadth of scholarship in Jewish studies, ‎rhetorical theory, and Biblical studies to develop a Jewish rhetorical framework for encountering the Other—human and divine—as holy, which I call a “covenant rhetoric.”
 This covenant rhetoric, I ‎assert, is not reserved for encounters with the divine, but is also applicable to human rhetorical ‎interactions. My dissertation thus offers a rhetorical model for encountering as holy the human ‎Others with whom we share our existence. As our diverse society continues to wrestle with the ‎ethical imperative towards the Other, I show how the Tanakh prompts us to reconsider the ‎rhetorical potential of encountering Otherness as holiness. In the process, I demonstrate ‎rhetoric’s centrality to religion, to spirituality, and to living an ethically-informed life. ‎

description: Practitioners who wish to build real-world applications that rely on ranking models, need to decide which modelling paradigm to follow. This is not an easy choice to make, as the research literature on this topic has been shifting in recent years. In particular, whilst Gradient Boosted Decision Trees (GBDTs) have reigned supreme for more than a decade, the flexibility of neural networks has allowed them to catch up, and recent works report accuracy metrics that are on par. Nevertheless, practical systems require considerations beyond mere accuracy metrics to decide on a modelling approach. This work describes our experiences in balancing some of the trade-offs that arise, presenting a case study on a short-video recommendation application. We highlight (1) neural networks' ability to handle large training data size, user- and item-embeddings allows for more accurate models than GBDTs in this setting, and (2) because GBDTs are less reliant on specialised hardware, they can provide an equally accurate model at a lower cost. We believe these findings are of relevance to researchers in both academia and industry, and hope they can inspire practitioners who need to make similar modelling choices in the future.

Forecasting Photo-Voltaic Solar Power in Electricity Systems

Year: 2013
Subjects: subject: Engineering--Electronics and Electrical
subject: PV Output Forecasting
subject: Similar Day Method

description: This thesis concentrates on short-term solar Photovoltaic (PV) power output forecasting at array and system levels. The analysis was conducted on three arrays around the world and one system level system in California. Array level power was found to have higher power fluctuation than system level power. Hence, the proposed array level forecasting involves a similar day-based data-preprocessing to deal with this fluctuation. The processed array level data was fed into a forecasting engine. A persistence model, an Auto Regressive Integrated Moving Average (ARIMA), a Radial Basis Function Neural Network (RBFNN) and a Least Squares Support Vector Machine (LS-SVM) model was used as a forecasting engine. This thesis also investigates the applicability of a number of established forecasting methods for system level solar power output forecasting. In particular, ARIMA, RBFNN and LS-SVM are examined and simulation results are provided. Through simulation, the best array level forecasting accuracy is achieved by a forecasting tool which combines the proposed similar day method and persistence model. The proposed similar day method works better than similar day methods in the literature and the best array level forecasting tool generated a more accurate forecast compared to a autoregressive with exogenous input (ARX) model in the literature. Due to the lower fluctuation of system level power data, system level forecasting has a better forecasting accuracy. The best performance is achieved through ARIMA model.

description: Many haloes of nearby disc galaxies contain faint and extended features, including loops, which are often interpreted as relics of satellite infall in the main galaxy's potential well. In most cases, however, the residual nucleus of the satellite is not seen, although it is predicted by numerical simulations. We test whether such faint and extended features can be associated to gas-rich, major mergers, which may also lead to disc rebuilding and thus be a corner stone for the formation of spiral galaxies. Using the TreeSPH code GADGET-2, we model the formation of an almost bulge-less galaxy similar to NGC 5907 (B/T $\le$ 0.2) after a gas-rich major merger. We indeed find that 3:1 major mergers can form features similar to the loops found in many galactic haloes, including in NGC 5907, and can reproduce an extended thin disc, a bulge, as well as the pronounced warp of the gaseous disc. Even though it remains difficult to fully cover the large volume of free parameters, the present modelling of the loops in NGC 5907 proves that they could well be the result of a major merger. It has many advantages over the satellite infall scenario; e.g., it solves the problem of the visibility of the satellite remnant, and it may explain some additional features in the NGC 5907 halo, as well as some gas properties of this system. For orbital parameters derived from cosmological simulations, the loops in NGC 5907 can be reproduced by major mergers (3:1 to 5:1) and possibly by intermediate mergers (5:1 to 12:1). The major merger scenario thus challenges the minor merger one and could explain many properties that haloes of spiral galaxies have in common, including their red colours and the presence of faint extended features.

description: This is an exploratory autoethnographic research project using anti-oppression theory on recovery from complex trauma. Data analysis focused on poetry that was generated during my graduate studies. Recovery is an emergent approach to mental health and is a process that has been virtually unresearched. A recovery intervention focuses on hope, taking responsibility for illness management, finding purposeful meaning in life, resuming control of one’s life, and redefinition of self. Emotion-focused coping, spirituality, peer support, and the unconditional positive regard of at least one person are also important in recovery. Hope for recovery gradually shifted from faith in trauma recovery and anti-oppression theories, through an evolving faith in Spirit, through an arising hope in myself, and through an emergent hope in relationships. Indicators of recovery suggested in the literature and reflected in the data include increased capacity for self-regulation, deconditioned traumatic memories, shedding of a victim identity, and identity reclamation.
On the classification of the almost contact metric manifolds

description: The vector space of the tensors $\mathcal F$ of type (0,3) having the same symmetries as the covariant derivative of the fundamental form of an almost contact metric manifold is considered. A scheme of decomposition of $\mathcal F$ into orthogonal components which are invariant under the action of $U(n)\times 1$ is given. Using this decomposition there are found 12 natural basic classes of almost contact metric manifolds. The classes of cosymplectic, $α$-Sasakian, $α$-Kenmotsu, etc. manifolds fit nicely to these considerations. On the other hand, many new interesting classes of almost contact metric manifolds arise.

Pumping the eccentricity of exoplanets by tidal effect

description: Planets close to their host stars are believed to undergo significant tidal interactions, leading to a progressive damping of the orbital eccentricity. Here we show that, when the orbit of the planet is excited by an outer companion, tidal effects combined with gravitational interactions may give rise to a secular increasing drift on the eccentricity. As long as this secular drift counterbalances the damping effect, the eccentricity can increase to high values. This mechanism may explain why some of the moderate close-in exoplanets are observed with substantial eccentricity values.

Coming of Age: Examining the Transition from Child to Adult Services for Persons with Autism

description: Autism Spectrum Disorder (ASD) presents pervasive challenges across the lifespan. Although systems of support exist for children affected by ASD, there are few resources available to assist individuals with ASD in the transition to adult care. With an exponential growth in the number of young persons diagnosed with ASD moving into adulthood, it is important to consider the multidimensional shifts associated with transition for the individual, his or her parent/caregiver, care planning, service resources, and vocation. Inherent to these processes are multiple barriers, opportunities, and disruptions that may require substantial adjustment, work, and time to understand and coordinate. The transitional period can be further confounded by impaired physical or mental abilities, health setbacks, forced dependence, misconceptions about condition, perceived outcomes, and care needs. The combination and overlap of these factors may occur simultaneously and can render transitions extremely difficult, warranting comprehensive and individualized planning for young persons with ASD.
The space of left orderings of a group with applications to topology
Creators: name: Clay, Adam J.
Publisher: name: University of British Columbia

description: A group is left orderable if there exists a strict total ordering of its elements that is invariant under multiplication from the left. The set of all left orderings of a group comes equipped with a natural topological structure and group action, and is called the space of left orderings. This thesis investigates the topology of the space of left orderings for a given group, by analyzing those left orderings that correspond to isolated points and by characterizing the orbits of the natural group action using maps from a certain free object. Lastly, we find an application of the space of left orderings in the field of 3-manifold topology, by using compactness to show that certain fundamental groups are not left orderable.

description: A theory for constructing quantum error correcting codes from Toric surfaces by the Calderbank-Shor-Steane method is presented. In particular we study the method on toric Hirzebruch surfaces. The results are obtained by constructing a dualizing differential form for the toric surface and by using the cohomology and the intersection theory of toric varieties. In earlier work the author developed methods to construct linear error correcting codes from toric varieties and derive the code parameters using the cohomology and the intersection theory on toric varieties. This method is generalized in section to construct linear codes suitable for constructing quantum codes by the Calderbank-Shor-Steane method. Essential for the theory is the existence and the application of a dualizing differential form on the toric surface. A.R. Calderbank, P.W. Shor and A.M. Steane produced stabilizer codes from linear codes containing their dual codes. These two constructions are merged to obtain results for toric surfaces. Similar merging has been done for algebraic curves with different methods by A. Ashikhmin, S. Litsyn and M.A. Tsfasman.

description: Precision spectroscopy of trapped HfF^+ will be used in a search for the permanent electric dipole moment of the electron (eEDM). While this dipole moment has yet to be observed, various extensions to the standard model of particle physics (such as supersymmetry) predict values that are close to the current limit. We present extensive survey spectroscopy of 19 bands covering nearly 5000 cm^(-1) using both frequency-comb and single-frequency laser velocity-modulation spectroscopy. We obtain high-precision rovibrational constants for eight electronic states including those that will be necessary for state preparation and readout in an actual eEDM experiment.
