description: We propose an experimental realization of the Spin Hall effect in graphene by illuminating a graphene sheet on top of a substrate with circularly polarized monochromatic light. The substrate induces a controllable Rashba type spin-orbit coupling which breaks the spin-degeneracy of the Dirac cones but it is gapless. The circularly polarized light induces a gap in the spectrum and turns graphene into a Floquet topological insulator with spin dependent edge states. By analyzing the high and intermediate frequency regimes, we find that in both parameter limits, the spin-Chern number can be tuned by the effective coupling strength of the charge particles to the radiation field and determine the condition for the photoinduced topological phase transition.

description: The search for empirical schemes to evidence the nonclassicality of large masses is a central quest of current research. However, practical schemes to witness the irreducible quantumness of an arbitrarily large mass are still lacking. To this end, we incorporate crucial modifications to the standard tools for probing the quantum violation of the pivotal classical notion of macrorealism (MR): while usual tests use the same measurement arrangement at successive times, here we use two different measurement arrangements. This yields a striking result: a mass-independent violation of MR is possible for harmonic oscillator systems. In fact, our adaptation enables probing quantum violations for literally any mass, momentum, and frequency. Moreover, coarse-grained position measurements at an accuracy much worse than the standard quantum limit, as well as knowing the relevant parameters only to this precision, without requiring them to be tuned, suffice for our proposal. These should drastically simplify the experimental effort in testing the nonclassicality of massive objects ranging from atomic ions to macroscopic mirrors in LIGO.

title: The future of environmental reporting and its consequences for the GRI : casesStudy: a comparative analysis of four companies

subject: Future of environmental reporting

description: Corporate action has always an impact - on the economy, the environment and the society. The Global Reporting Initiative (GRI) has been introduced in order to provide uniform reporting standards for all companies independent from their field and country of operation or their size. Effective environmental reporting is necessary in order to take actions, which are required for decreasing negative impacts on the environment. Thus, reporting standards and methods have to be continuously improved and adopted to our dynamic environment. In this thesis, a conflation of a theoretical approach with a practical approach leads to a conclusion on these probable future improvements and developments of environmental reporting frameworks, especially the GRI. On the theoretic side, critical remarks of academics regarding the GRI are analyzed. The practical approach comprises a comparative analysis of environmental reports of four companies in two different sectors, respectively two companies in each sector. This approach allows both, intra-sectorial and cross-sectorial comparison. The compared companies are VERBUND and OMV in the field of energy as well as Wienerberger and Palfinger in the field of construction materials. The juxtaposition of the theoretic and the practical approach results in the conclusion that environmental reporting steers towards a more mandatory framework. Furthermore, environmental reporting moves towards the model of Integrated Reporting, which merges the reports for the economy, the environment and the society. The GRI has to transit from an approach of compatibility with other international reporting frameworks to one of complementarity in order to maintain its prominence. The comparative analysis provides evidence that the content of environmental reports are barely comparable and that such comparison between industries is not expedient. Therefore, complete standardization cannot be the goal of future developments of environmental reporting; instead, the goal of transparency becomes more prominent. Moreover, environmental reporting frameworks will increasingly emphasize the importance of a comprehensive materiality principle, which is crucial for the meaningfulness of environmental reports.

description: We show how a recent proposal to obtain the distribution of conductances in three dimensions (3D) from a generalized Fokker-Planck equation for the joint probability distribution of the transmission eigenvalues can be implemented for all strengths of disorder by numerically evaluating certain correlations of transfer matrices. We then use this method to obtain analytically, for the first time, the 3D conductance distribution in the insulating regime and provide a simple understanding of why it differs qualitatively from the log-normal distribution of a quasi one-dimensional wire.

description: Surface currents provide a general way to model static magnetic fields in source-free volumes. To facilitate the use of surface currents in magneto-quasistatic problems, we have implemented a set of computational tools in a Python package named bfieldtools. In this work, we describe the physical and computational principles of this toolset. To be able to work with surface currents of arbitrary shape, we discretize the currents on triangle meshes using piecewise-linear stream functions. We apply analytical discretizations of integral equations to obtain the magnetic field and potentials associated with the discrete stream function. In addition, we describe the computation of the spherical multipole expansion and a novel surface-harmonic expansion for surface currents, both of which are useful for representing the magnetic field in source-free volumes with a small number of parameters. Last, we share examples related to magnetic shielding and surface-coil design using the presented tools.

description: Recent studies have revealed that the Multiple Populations (MPs) phenomenon does not occur only in ancient and massive Galactic globular clusters (GCs), but it is also observed in external galaxies, where GCs sample a wide age range with respect to the Milky Way. However, for a long time, it was unclear whether we were looking at the same phenomenon in different environments or not. The first evidence that the MPs phenomenon is the same regardless of cluster age and host galaxy came out recently when an intermediate-age cluster from the Small Magellanic Cloud, Lindsay 1, and a Galactic GC have been directly compared. By complementing those data with new images from the Hubble Space Telescope (HST), we extend the comparison to two clusters of different ages: NGC 2121 ($\sim$2.5Gyr) and NGC 1783 ($\sim$1.5Gyr), from the Large Magellanic Cloud. We find a clear correlation between the RGB width in the pseudo-colour $C_{F275W,F343N,F438W}$ and the age of the cluster itself, with the older cluster having larger $σ(C_{F275W,F343N,F438W})^{RGB}$ and vice-versa. Unfortunately, the $σ$ values cannot be directly linked to the N-abundance variations within the clusters before properly taking account the effect of the first dredge-up. Such HST data also allow us to explore whether multiple star-formation episodes occurred within NGC 2121. The two populations are indistinguishable, with an age difference of only 6$\pm$12 Myr and an initial Helium spread of 0.02 or lower. This confirms our previous results, putting serious constraints on any model proposed to explain the origin of the chemical anomalies in GCs.

Mathematics of Computation 89, no. 324 (2020)] for state-dependent FBSDEs with reflections to path-dependent FBSDEs with reflections, by adding the signature layer to the backward scheme. Our algorithm applies to both European and American type option pricing problems while the payoff function depends on the whole paths of the underlying forward stock process. We prove the convergence analysis of our numerical algorithm with explicit dependence on the truncation order of the signature and the neural network approximation errors. Numerical examples for the algorithm are provided including: Amerasian option under the Black-Scholes model, American option with a path-dependent geometric mean payoff function, and the Shiryaev's optimal stopping problem.

The usefulness and ethical status of language entrance/placement testing at a post-secondary institution
Creators: name: Golder, Katherine Jane
Publisher: name: University of British Columbia
Year: 2010

description: Often language entrance and placement testing at post-secondary institutions is used as a gatekeeping mechanism--sorting people in and out, keeping out those who don’t exactly fit their desired profile. This is troubling in a country as multicultural as Canada since testing language can be seen as testing culture. Testing, therefore, may be perceived as a tool for restricting minority access. This has been highlighted by recent media coverage of foreign-trained professionals and their restricted access to post-secondary institutions to gain Canadian credentials. However, testing can and should do more than gatekeeping: among other purposes, testing can be an educational, diagnostic tool, and feedback on results can give test takers insight into their strengths and weaknesses. While the classic criteria of reliability and validity are important in evaluating testing, we must also include criteria beyond these. For testing to be considered ’good’ it must be useful (e.g. demonstrate reliability, validity, practicality) and ethical (ensure all test takers are treated equally, demonstrate respect for persons, and maximize the benefits to stakeholders). This research project is an exploratory qualitative examination of the usefulness and ethical status of language entrance/placement testing at a Canadian post-secondary institution. Opinions and perceptions of testing were obtained from a variety of stakeholders in the testing process to determine how ethical and useful testing was and was perceived to be. The stakeholder groups involved were test takers (both successful and unsuccessful), test score users (including instructors and administrators), and test developers and administrators. Data was obtained through focus groups, interviews, and questionnaires between September and November of 2005. The main finding of this research was that while the testing process met certain criteria for ethics and usefulness, there were a variety of areas that could be improved. Overall, a lack of communication between test developers/administrators and other stakeholder groups, as well as a general lack of transparency in the testing process, led to widespread misunderstandings of the tests’ content and purposes. This, in turn, created a lack of respect for the authority of testing, and a lack of face validity.

description: We investigate the formation mechanism for the observed nearly polar aligned (perpendicular to the binary orbital plane) debris ring around the eccentric orbit binary 99 Herculis. An initially inclined nonpolar debris ring or disc will not remain flat and will not evolve to a polar configuration, due to the effects of differential nodal precession that alter its flat structure. However, a gas disc with embedded well coupled solids around the eccentric binary may evolve to a polar configuration as a result of pressure forces that maintain the disc flatness and as a result of viscous dissipation that allows the disc to increase its tilt. Once the gas disc disperses, the debris disc is in a polar aligned state in which there is little precession. We use three-dimensional hydrodynamical simulations, linear theory, and particle dynamics to study the evolution of a misaligned circumbinary gas disc and explore the effects of the initial disc tilt, mass, and size. We find that for a wide range of parameter space, the polar alignment timescale is shorter than the lifetime of the gas disc. Using the observed level of alignment of 3 deg. from polar, we place an upper limit on the mass of the gas disc of about 0.014 M_sun at the time of gas dispersal. We conclude that the polar debris disc around 99 Her can be explained as the result of an initially moderately inclined gas disc with embedded solids. Such a disc may provide an environment for the formation of polar planets.

description: The work aims at formulating hypothesis on the actual alterity (Kirwan, 2004) of those realities that either define themselves or have been considered in the Calabria political, social and scientific contexts as examples of “filiere corte”, that is as food practices characterised by the AFN (Alternative Food Networks) features, in the way they have been defined by the international scientific literature. The study rises from the need to avoid the “conceptual conflation” (Tregear, 2011), which biased the AFN comprehension at the international level and is finding a fertile land within the Italian scientific and empiric reality where scholars discuss the “filiere corte” initiatives in the frame of the AFN studies although warning on the possibility of overlapping existing practices typical of an agri-food system that is not completely modernised (Malassis e Ghersi, 1998; Rossi et al., 2008). Concerning this last point Calabria doesn’t lag behind requiring an investigation on the actual nature and alterity of those realities framed among the “filiera corta” initiatives. Favouring a theoretical frame that allows considering the existing realities as dynamically interacting, rather than opposing each other, Convention Theory is the theoretical starting point operationalized through the Granovetter (1985) concept of “emebeddedness”: “filiere corte” are identified as one of the possible conventions organizing the Calabria agri-food system and shaping in the relation with the other agri-food, political and social systems. After an empiric analysis, three general typologies have been identified among those either self-defined or recognised as “filiere corte”: Farmer’s Market, GAS and GODO. Moreover three hypothesis on their technical, social and political “alterity” have been introduced: in the first case it could derive from their ability to close the food chain, merging supply and demand; secondly it could be founded on their capacity to stimulate local form of social cooperation; third they seem to require an innovative participatory approach in order to be politically framed. Each of the three hypothesis are theoretically elaborated and require further empirical tests.

description: We present a two-component Machine Learning (ML) based approach for classifying astronomical images by data-quality via an examination of sources detected in the images and image pixel values from representative sources within those images. The first component, which uses a clustering algorithm, creates a proper and small fraction of the image pixels to determine the quality of the observation. The representative images (and associated tables) are ~800 times smaller than the original images, significantly reducing the time required to train our algorithm. The useful information in the images is preserved, permitting them to be classified in different categories, but the required storage is reduced. The second component, which is a deep neural network model, classifies the representative images. Using ground-based telescope imaging data, we demonstrate that the method can be used to separate 'usable' images from those that present some problems for scientific projects -- such as images that were taken in sub-optimal conditions. This method uses two different data sets as input to a deep model and provides better performance than if we only used the images' pixel information. The method may be used in cases where large and complex data sets should be examined using deep models. Our automated classification approach achieves 97% agreement when compared to classification generated via manual image inspection. We compare our method with traditional results and show that the method improves the results by about 10%, and also presents more comprehensive outcomes.

description: As Large Language Models and Natural Language Processing (NLP) technology rapidly develop and spread into daily life, it becomes crucial to anticipate how their use could harm people. One problem that has received a lot of attention in recent years is that this technology has displayed harmful biases, from generating derogatory stereotypes to producing disparate outcomes for different social groups. Although a lot of effort has been invested in assessing and mitigating these biases, our methods of measuring the biases of NLP models have serious problems and it is often unclear what they actually measure. In this paper, we provide an interdisciplinary approach to discussing the issue of NLP model bias by adopting the lens of psychometrics -- a field specialized in the measurement of concepts like bias that are not directly observable. In particular, we will explore two central notions from psychometrics, the construct validity and the reliability of measurement tools, and discuss how they can be applied in the context of measuring model bias. Our goal is to provide NLP practitioners with methodological tools for designing better bias measures, and to inspire them more generally to explore tools from psychometrics when working on bias measurement tools.

description: We present a quantitative method to classify galaxies, based on multi-wavelength data and elaborated from the properties of nearby galaxies. Our objective is to define an evolutionary method that can be used for low and high redshift objects. We estimate the concentration of light (C) at the galaxy center and the 180 degree-rotational asymmetry (A), computed at several wavelengths, from ultraviolet (UV) to I-band. The variation of the indices of concentration and asymmetry with the wavelength reflects the proportion and the distribution of young and old stellar populations in galaxies. In general C is found to decrease from optical to UV, and A is found to increase from optical to UV: the patchy appearance of galaxies in UV with no bulge is often very different from their counterpart at optical wavelengths, with prominent bulges and more regular disks. The variation of C and A with the wavelength is quantified. By this way, we are able to distinguish five types of galaxies that we call spectro-morphological types: compact, ringed, spiral, irregular and central-starburst galaxies, which can be differentiated by the repartition of their stellar populations. We discuss in detail the morphology of galaxies of the sample, and describe the morphological characteristics of each spectro-morphological type. We apply spectro-morphology to three objects at a redshift z=1 in the Hubble Deep Field North, that gives encouraging results for applications to large samples of high-redshift galaxies. This method of morphological classification could be used to study the evolution of the morphology with the redshift and is expected to bring observational constraints on scenarios of galaxy evolution.

description: The interaction and dimension of points are two important axes in designing point operators to serve hierarchical 3D models. Yet, these two axes are heterogeneous and challenging to fully explore. Existing works craft point operator under a single axis and reuse the crafted operator in all parts of 3D models. This overlooks the opportunity to better combine point interactions and dimensions by exploiting varying geometry/density of 3D point clouds. In this work, we establish PIDS, a novel paradigm to jointly explore point interactions and point dimensions to serve semantic segmentation on point cloud data. We establish a large search space to jointly consider versatile point interactions and point dimensions. This supports point operators with various geometry/density considerations. The enlarged search space with heterogeneous search components calls for a better ranking of candidate models. To achieve this, we improve the search space exploration by leveraging predictor-based Neural Architecture Search (NAS), and enhance the quality of prediction by assigning unique encoding to heterogeneous search components based on their priors. We thoroughly evaluate the networks crafted by PIDS on two semantic segmentation benchmarks, showing ~1% mIOU improvement on SemanticKITTI and S3DIS over state-of-the-art 3D models.

description: We study theoretically the equilibrium phase behaviour of a mixture of polydisperse hard-sphere colloids and monodisperse polymers, modelled using the Asakura-Oosawa model within the free volume approximation of Lekkerkerker et al. We compute full phase diagrams in the plane of colloid and polymer volume fractions, using the moment free energy method. The intricate features of phase separation in pure polydisperse colloids combine with the appearance of polymer-induced gas-liquid coexistence to give a rich variety of phase diagram topologies as the polymer-colloid size ratio and the colloid polydispersity are varied. Quantitatively, we find that polydispersity disfavours fluid-solid against gas-liquid separation, causing a substantial lowering of the threshold value above which stable two-phase gas-liquid coexistence appears. Phase splits involving two or more solids can occur already at low colloid concentration, where they may be kinetically accessible. We also analyse the strength of colloidal size fractionation. When a solid phase separates from a fluid, its polydispersity is reduced most strongly if the phase separation takes place at low colloid concentration and high polymer concentration, in agreement with experimental observations. For fractionation in gas-liquid coexistence we likewise find good agreement with experiment, as well as with perturbative theories for near-monodisperse systems.

Imaginary-time updates are computed by stochastic sampling of the coupled cluster vector function: each term is evaluated as a randomly realised diagram in the connected expansion of the similarity-transformed Hamiltonian. We highlight similarities and differences between deterministic and stochastic linked coupled cluster theory when the latter is re-expressed as a sampling of the diagrammatic expansion, and discuss details of our implementation that allow for a walker-less realisation of the stochastic sampling. Finally, we demonstrate that in the presence of locality, our algorithm can obtain a fixed errorbar per electron while only requiring an asymptotic computational effort that scales quartically with system size, independently of truncation level in coupled cluster theory. The algorithm only requires an asymptotic memory costs scaling linearly, as demonstrated previously. These scaling reductions require no ad hoc modifications to the approach.
Teaching and learning Shakespeare through song
Creators: name: Mikulin, Michael
Publisher: name: University of British Columbia

description: Shakespeare's plays are filled with music. Over 70 songs can be found in the Shakespeare canon, and no less than 32 of the plays make reference to music or musical matters in the text itself (Naylor, 1965, p. 3). In addition to songs that advance the action, known as mimetic music, performances of Shakespearean drama often make use of non-mimetic music - that is, the incidental music used at the start and end of the plays to entertain the audience (Duffin, 2004, p.11). While much innovative research has resulted in new and exciting ways to teach Shakespeare (i.e., O'Brien, 1993; Davis & Salomone, 1993; Gibson, 1998), the possibility of exploring musical settings in the context of teaching Shakespeare is often overlooked, possibly due to a lack of accessible information and resources. This thesis explores how understanding of Shakespearean drama might be enriched through attention to the song texts. It is comprised of three main sections: 1) an examination of the history of song in Shakespearean text; 2) a presentation of the author's original arrangements for five song texts accompanied by discussion of how the composition process required sophisticated engagement with the text; and 3) a reflection on the author's experiences inviting Grade 10 English students to compose original settings for Shakespearean songs employing a computer-based music making application. The print manuscript is accompanied by a hypermedia compilation for classroom use that features musical settings (both historical and original), song texts, and practical resources for teachers. Additional materials, including streamed music files of the author's original song settings, are available at www.shakesonqs.com.

description: The k-string tensions are explored in the 4-d $[U(1)]^{N-1}$-invariant dual Abelian-Higgs-type theory. In the London limit of this theory, the Casimir scaling is found in the approximation when small-sized closed dual strings are disregarded. When these strings are treated in the dilute-plasma approximation, explicit corrections to the Casimir scaling are found. The leading correction due to the deviation from the London limit is also derived. Its N-ality dependence turns out to be the same as that of the first non-trivial correction produced by closed strings. It also turns out that this N-ality dependence coincides with that of the leading correction to the k-string tension, which emerges by way of the non-diluteness of the monopole plasma in the 3-d SU(N) Georgi-Glashow model. Finally, we prove that, in the latter model, Casimir scaling holds even at monopole densities close to the mean one, provided the string world sheet is flat.

description: We analyze and further develop a new method to represent the quantum state of a system of $n$ qubits in a phase space grid of $N\times N$ points (where $N=2^n$). The method, which was recently proposed by Wootters and co--workers (Gibbons {\it et al.}, quant-ph/0401155), is based on the use of the elements of the finite field $GF(2^n)$ to label the phase space axes. We present a self--contained overview of the method, we give new insights on some of its features and we apply it to investigate problems which are of interest for quantum information theory: We analyze the phase space representation of stabilizer states and quantum error correction codes and present a phase space solution to the so--called ``mean king problem''.

description: We present a general class of entanglement criteria for continuous variable systems. Our criteria are based on the Husimi $Q$-distribution and allow for optimization over the set of all concave functions rendering them extremely general and versatile. We show that several entropic criteria and second moment criteria are obtained as special cases. Our criteria reveal entanglement of families of states undetected by any commonly used criteria and provide clear advantages under typical experimental constraints such as finite detector resolution and measurement statistics.

Gravitational wave radiation from the coalescence of white dwarfs

description: We compute the emission of gravitational radiation from the merging of a close white dwarf binary system. This is done for a wide range of masses and compositions of the white dwarfs, ranging from mergers involving two He white dwarfs, mergers in which two CO white dwarfs coalesce to mergers in which a massive ONe white dwarf is involved. In doing so we follow the evolution of binary system using a Smoothed Particle Hydrodynamics code. Even though the coalescence process of the white dwarfs involves considerable masses, moving at relatively high velocities with a high degree of asymmetry we find that the signature of the merger is not very strong. In fact, the most prominent feature of the coalescence is that in a relatively small time scale (of the order of the period of the last stable orbit, typically a few minutes) the sources stop emitting gravitational waves. We also discuss the possible implications of our calculations for the detection of the coalescence within the framework of future space-borne interferometers like LISA.

description: O aumento da necessidade de competir conduz as cooperativas a posturas mais estratégicas, como integração produtiva e distributiva, além de fusões com cooperativas nacionais e estrangeiras e desenvolvimento de marcas fortes, como o surgimento de estruturas mais adequadas para sobreviver nesse novo contexto marcado pela abertura econômica na década de 1990. Assim, o objetivo central desta pesquisa é verificar como as cooperativas de leite, e mais especificamente a Cooperativa de Lorena e Piquete, se reestruturaram frente a essas mudanças nas características do mercado. E para isso, realizou-se um estudo de caso em uma cooperativa localizada em uma importante bacia leiteira – Vale do Paraíba - do estado de São Paulo, com o intuito de verificar a postura estratégica adota por esta frente às mudanças de mercado. O conjunto conceitual que sustenta a análise são as quatro posturas estratégicas que podem ser adotadas pelas empresas, propostas por Oliveira (1999). Observou-se que a organização cooperativa estudada passou por um processo de reestruturação focando a adoção de uma postura estratégica de sobrevivência. E isto foi possível mediante uma união de Cooperativas. Sendo assim, a saída encontrada após um período de prejuízos, visando uma melhor remuneração do produtor, foi o fechamento da usina de beneficiamento e a permanência no sistema Central, para se fortalecer através da redução de custos e do desinvestimento.
The far-UV Interstellar Radiation Field in Galactic Disks: Numerical and Analytic Models

description: The intensity of the far-ultraviolet (FUV; 6-13.6 eV) interstellar radiation field (ISRF) in galaxies determines the thermal and chemical evolution of the neutral interstellar gas and is key for interpreting extragalactic observations and for theories of star-formation. We run a series of galactic disk models and derive the FUV ISRF intensity as a function of the dust-to-gas ratio, star-formation rate density, gas density, scale radius, and observer position. We develop an analytic formula for the median FUV ISRF flux. We identify two dimensionless parameters in the problem: (1) the dimensionless galactic radius, $X$, which measures the radial extent of FUV sources (OB stellar associations) in the disk; (2) the opacity over the inter-source distance, $τ_{\star}$, which measures the importance of dust absorption. These parameters encapsulate the dependence on all of the physical parameters. We find that there exists a critical $τ_{\star}$, or equivalently a critical dust-to-gas ratio, $Z_{d,{\rm crit}}' \approx 0.01-0.1$ the Milky Way value, at which the ISRF changes behavior. For $Z'_d>Z_{d,{\rm crit}}'$ the ISRF is limited by dust absorption. With decreasing $Z'_d$, the ISRF intensity increases as more sources contribute to the flux. For $Z'_d < Z_{d,{\rm crit}}'$ the ISRF saturates as the disk becomes optically thin. We find that the ISRF per star-formation rate density in low metallicity systems, such as dwarf and high redshift galaxies, is higher by up to a factor of 3-6 compared to their Milky-Way counterparts. We discuss implications to the potential mechanisms that regulate star-formation in low metallicity galaxies.
