    Observational Cosmology in Macroscopic Gravity

    Get PDF
    We discuss the construction of cosmological models within the framework of Macroscopic Gravity (MG), which is a theory that models the effects of averaging the geometry of space-time on large scales. We find new exact spatially homogeneous and isotropic FLRW solutions to the MG field equations, and investigate large-scale perturbations around them. We find that any inhomogeneous perturbations to the averaged geometry are severely restricted, but that possible anisotropies in the correlation tensor can have dramatic consequences for the measurement of distances. These calculations are a first step within the MG approach toward developing averaged cosmological models to a point where they can be used to interpret real cosmological data, and hence to provide a working alternative to the "concordance" LCDM model.Comment: 22 page

    OBJECTIVES: To select, present, and summarize the best papers in 2022 for the Knowledge Representation and Management (KRM) section of the International Medical Informatics Association (IMIA) Yearbook. METHODS: We conducted PubMed queries and followed the IMIA Yearbook guidelines for performing biomedical informatics literature review to select the best papers in KRM published in 2022. RESULTS: We retrieved 1,847 publications from PubMed. We nominated 15 candidate best papers, and two of them were finally selected as the best papers in the KRM section. The topics covered by the candidate papers include ontology and knowledge graph creation, ontology applications, ontology quality assurance, ontology mapping standard, and conceptual model. CONCLUSIONS: In the KRM best paper selection for 2022, the candidate best papers encompassed a broad range of topics, with ontology and knowledge graph creation remaining a considerable research focus

    'I act this way because why?' Prior knowledges, teaching for change, imagining new masculinities

    Get PDF
    This article begins by outlining some of the prior knowledges brought by undergraduate students to an introduction to gender studies class in the Women's and Gender Studies Department at the University of the Western Cape, South Africa. I show that, at the beginning of the course, students clearly understand gender to refer to women and femininity, imagining femininity (but not masculinity) to be responsive to social change. I suggest that, in the face of these prior knowledges, it is important to focus on masculinity as performance, as a cultural artefact and one that is deeply harmful to South African men. Student experiences of this teaching and learning suggest that it offers possibilities for imagining men as allies and beneficiaries - rather than enemies - in the struggle for gender equity

    The impact of world heritage site designation on local communities - A case study of Ogimachi, Shirakawa-mura, Japan

    Get PDF
    The paper examines economic, socio-cultural, physical and attitudinal changes in/around World Heritage Site (WHS) Ogimachi since WHS designation from the local communities' standpoint and explores the background of these changes and views. Both positive and negative changes for local communities in/around WHS Ogimachi after WHS listing are identified. There are three main factors behind these changes: the extensive and rapid tourism development after WHS inscription; the high level of appeal of a WHS status for domestic tourists; and local people's attitudes towards conservation of the cultural environment and WHS status. In addition to its conservation plan, WHS Ogimachi must have a comprehensive tourism management plan for its successful future as a place to live, as a WHS and a tourist destination

    ABA Section of Taxation Report of the Task Force on Judicial Deference

    Recognizing the need for clearer standards regarding the degree of deference that the federal courts should confer on guidance issued by the Department of Treasury and the Internal Revenue Service, the Tax Section, under the direction of former ABA Section of Taxation Chair Pamela F. Olson, created a Task Force on Judicial Deference in 2000. It was charged with the mission of not only examining the state of the law pertaining to judicial deference across the broad range of administrative pronouncements issued by the Treasury and the IRS, but also sharing its conclusions and possible solutions with the Section of Taxation and the profession at large. Based on the agency-by-agency approach required by the Supreme Court in United States v. Mead Corporation, 533 U.S. 218(2001), the Task Force analyzed the differences in the degree of authority and degree of deliberation underlying the various forms of such guidance and the impact of those differences on whether, and to what degree, judicial deference is appropriate.
