    Contrast of Electron Microscopy Images of Amorphous Objects by O.Ya. Svatiuk

    Published 2016-03-01
    “…It has been proposed to determine the contrast in electron microscopy image via the total electron fluxes scattered beyond the aperture diaphragm by local areas of the object under study to analyze quantitatively the amplitude (absorption) contrast of the amorphous objects with different types of heterogeneities of the atomic and continual structure. The significant properties of the determined contrast are its linear dependence on the difference of electron beam fluxes that form the image and a convenient range of variation from 0 to 1 relative units.…”

    Mixed traditions: evaluating telecommunications transparency by Ben Ballard, Christopher Parsons

    Published 2022-01-01
    “…Our analysis suggests that effective reports are targeted, in that they embody both verifiable and performative approaches to transparency, and also are sustainable, insofar as they evolve in their scope and structure while remaining regularly published. Emergent from this evaluation, we can better explain why different companies, in different jurisdictions, demonstrate variation in their adoption of effective transparency reporting practices over the last decade.…”
