    Details
    Publication Date: 2022-04-28
    Description: Homelessness & Health in Canada explores, for the first time, the social, structural, and environmental factors that shape the health of homeless persons in Canada. Covering a wide range of topics from youth homelessness to end-of-life care, the authors strive to outline policy and practice recommendations to respond to the ongoing public health crisis. This book is divided into three distinct but complimentary sections. In the first section, contributors explore how homelessness affects the health of particular homeless populations, focusing on the experiences of homeless youth, immigrants, refugees and people of Aboriginal ancestry. In the second section, contributors investigate how housing and public health policy as well as programmatic responses can address various health challenges, including severe mental illness and HIV/AIDS. In the final section, contributors highlight innovative Canadian interventions that have shown great promise in the field. Together, they form a comprehensive survey of an all too important topic and serve as a blueprint for action.

    Doing Research: A New Researcher’s Guide (2022)
    Springer Nature | Springer
    Details
    Publication Date: 2024-03-29
    Description: This book is about scientific inquiry. Designed for early and mid-career researchers, it is a practical manual for conducting and communicating high-quality research in (mathematics) education. Based on the authors’ extensive experience as researchers, as mentors, and as members of the editorial team for the Journal for Research in Mathematics Education (JRME), this book directly speaks to researchers and their communities about each phase of the process for conceptualizing, conducting, and communicating high-quality research in (mathematics) education. In the late 2010s, both JRME and Educational Studies in Mathematics celebrated 50 years of publishing high-quality research in mathematics education. Many advances in the field have occurred since the establishment of these journals, and these anniversaries marked a milestone in research in mathematics education. Indeed, fifty years represents a small step for human history but a giant leap for mathematics education. The educational research community in general (and the mathematics education community in particular) has strongly advocated for original research, placing great emphasis on building knowledge and capacity in the field. Because it is an interdisciplinary field, mathematics education has integrated means and methods for scientific inquiry from multiple disciplines. Now that the field is gaining maturity, it is a good time to take a step back and systematically consider how mathematics education researchers can engage in significant, impactful scientific inquiry.

    The simulation of switching in polycrystalline ferroelectric ceramics (1998)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 84 (1998), S. 1530-1540

    Notes: A polarization switching model for polycrystalline ferroelectric ceramics has been developed. It is assumed that a single ferroelectric crystallite in a ceramic, which is subjected to an electric field and/or a stress, undergoes a complete polarization change and a corresponding strain change if the resulting reduction in potential energy exceeds a critical value per unit volume of switching material. The crystallite's switch causes a change in the interaction of its field and stress with the surrounding crystallites, which is modeled by the Eshelby inclusion method to provide a mean field estimate of the effect. Thus the model accounts for the effects of the mean electric and stress fields arising from the constraints presented by surrounding crystallites as well as the externally applied mechanical and electrical loads. The switching response of the ceramic polycrystal is obtained by averaging over the behavior of a large number of randomly oriented crystallites. The model, along with the linear dielectric, elastic, and piezoelectric behavior of the material, is implemented in a computer simulation. A fit to experimental electric displacement versus electric field, strain versus electric field, and strain versus stress curves of a ceramic lead lanthanum zirconate titanate PLZT at room temperature is used to obtain material parameters. The model then successfully predicts the electric displacement and strain hysteresis loops for the PLZT under varying electric fields with a constant applied stress. © 1998 American Institute of Physics.

    Switching in ferroelectric polycrystals (2000)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: The Rayleigh law and a propagating switching region of a ferroelectric polycrystal are studied with a finite element model. Each crystallite, represented by a cubic element in a finite element mesh, is a single domain that switches completely without a simulated domain wall motion. The model involves only electric field induced (i.e., ferroelectric) switching. Under a low applied field, the model reproduces the Rayleigh law. The model predicts that a switching crystallite and its follow-up switching crystallite are likely to be the nearest neighbors and that the switching sequence of the crystallites forms the shape of an ellipsoid the major axis of which is parallel with the applied field direction. A spontaneous polarization reverses by direct 180° reorientation if only one layer of the finite elements between two electrodes is simulated but reverses by two consecutive 90° domain reorientations if the number of stacked layers between the electrodes is equal to two or greater. © 1999 American Institute of Physics.

    A general BRST approach to string theories with zeta function regularizations (1999)
    College Park, Md. : American Institute of Physics (AIP)
    Journal of Mathematical Physics 40 (1999), S. 4639-4657

    ISSN: 1089-7658

    Topics: Mathematics , Physics
    Notes: We propose a new general BRST approach to string and string-like theories that have a wider range of applicability than, e.g., the conventional conformal field theory method. The method involves a simple general regularization of all basic commutators, which makes all divergent sums expressible in terms of zeta functions from which finite values then may be extracted in a rigorous manner. The method is particularly useful in order to investigate possible state space representations to a given model. The method is applied to three string models: The ordinary bosonic string, the tensionless string, and the conformal tensionless string. We also investigate different state spaces for these models. The tensionless string models are treated in detail. Although we mostly rederive known results, they appear in a new fashion that deepens our understanding of these models. Furthermore, we believe that our treatment is more rigorous than most of the previous ones. In the case of the conformal tensionless string we find a new solution for d=4. © 1999 American Institute of Physics.

    The Semi-Infinite Cohomology of Affine Lie Algebras (1998)
    Springer
    Communications in mathematical physics 194 (1998), S. 591-611

    Notes: Abstract: We study the semi-infinite or BRST cohomology of affine Lie algebras in detail. This cohomology is relevant in the BRST approach to gauged WZNW models. Our main result is to prove necessary and sufficient conditions on ghost numbers and weights for non-trivial elements in the cohomology. In particular we prove the existence of an infinite sequence of elements in the cohomology for non-zero ghost numbers. This will imply that the BRST approach to the topological WZNW model admits many more states than a conventional coset construction. This conclusion also applies to some non-topological models. Our work will also contain results on the structure of Verma modules over affine Lie algebras. In particular, we generalize the results of Verma and Bernstein-Gel'fand-Gel'fand, for finite dimensional Lie algebras, on the structure and multiplicities of Verma modules. The present work gives the theoretical basis of the explicit construction of the elements in cohomology presented previously. Our analysis proves and makes use of the close relationship between highest weight null-vectors and elements of the cohomology.

    Interpretation and Utilization of Effect and Concentration Data Collected in an in Vivo Pharmacokinetic and in Vitro Pharmacodynamic Study (1993)

    Notes: Abstract The effect (E) of some drugs may be monitored in vitro using the plasma drug concentration (C) following the in vivo dosing of drug. When using a specific analytical assay, counterclockwise hysteresis in the E vs C relationship can be explained only by the presence of an agonistic metabolite (M A); the extent of hysteresis will depend upon the pharmacokinetics and relative "potency” of C and M A. If a nonspecific assay is used, plots of E vs C may actually relate to E vs total agonist (C + M A), and unusual hysteresis may be observed, e.g., clockwise hysteresis when C is more "potent” than M A. Here, we simulate data for three models of relative C and M A pharmacokinetics. The E vs C and E vs M A data are simulated for both linear and noncompetitive agonist E max models. When C and M A are equally potent, hysteresis will not be observed in a plot of E vs C + M A. However, when C and M A are of differing "potencies,” hysteresis will be observed (the direction of hysteresis is dependent on the relative potency of C and M A). By appropriately "weighting” a respective agonist (C or M A), hysteresis will "collapse” and the relative potencies of C and M A can be estimated.
