    This essay is a multidisciplinary case study of environmental injustice. It demonstrates that misuse of the environment can ultimately impact humans unjustly and further that attempts to remediate injustice in one area merely shifts the burden of injustice to others. After providing the historical, sociological and scientific facts surrounding the 50-acre site, an ethical assessment is presented. It was determined that the actors in this case study were not employing any ethical valuing in their decision making process, but rather relied upon economic values to make their choices. The authors then suggest that judging them from within their own economic valuing system that the actors’ decisions had failed to meet their own values, i.e. good economics

    Low Energy Electron Diffraction of Thin Chromium Films on a Palladium Crystal

    The surface-surface interactions between a sample of palladium and a thin film of chromium grown on the surface were studied using Low Energy Electron Diffraction (LEED) and X-Ray Photoelectron Spectroscopy (XPS). The combination of the thin film and the properties of LEED allowed for close study of interaction of the chromium atoms on the surface of the palladium without penetrating into the palladium bulk. The geometric arrangement of the atoms and lattice that the chromium created as it bonded to the palladium was of great interest. The exact arrangement of the atoms as they attempt to fit together can be used to predict the properties of the interactions, along with the differences between thin and thick films of material, leading to new uses of the material

    Exploring Gluon Polarization in the Proton with STAR Jet Data and the NNPDF Polarized Parton Distributions

    The NNPDF Polarized Parton Distribution Functions (PDF) are a PDF set made using a neural network technique rather than using traditional functional forms. The NNPDF polarized parton distribution includes one hundred different fits, or replicas, that are all considered equally probable. The NNPDF replicas were used to calculate the longitudinal double-spin asymmetry, ALLA_{LL}, for inclusive jet production at s=200 GeV\sqrt{s} = \text{200 GeV}. The calculations were compared to STAR inclusive jet ALLA_{LL} results from 2006 and 2009, and the χ2\chi^{2} was determined for each replica. The χ2\chi^{2} values were used in a reweighting procedure, which the NNPDF group developed, for the inclusion of new data into an existing PDF fit. After the reweighting, the polarization of the gluon is examined. The STAR data provide significant constraining power on the gluon polarization, compared to the unweighted NNPDF set

Springer. https://doi.org/10.1007/978-3-030-51005-3_20Information systems (IS) play an important role in contemporary society, but critical questions remain on their impact on democracy. This study aims to contribute to a better understanding of this phenomenon. In order to do so, the study develops an innovative methodological approach. Drawing from Design Science Research (DSR), we build conceptual pairs between core preoccupations explored by critical thought on democracy and available problem-solving information technologies. The study does not aim at an exhaustive analysis of problems and solutions; this would be unfeasible, considering the limitations of journal article format. Rather, it aims at early-stage methodology incorporation across disciplines that draw from different research paradigms. The findings will offer a preliminary probe on the analytical input of DSR conceptual artefacts in examining functional links between information systems and political outcomes.authorsversionpublishe

    Deep Underground Neutrino Experiment (DUNE) Near Detector Conceptual Design Report

    No full text
    International audienceThe Deep Underground Neutrino Experiment (DUNE) is an international, world-class experiment aimed at exploring fundamental questions about the universe that are at the forefront of astrophysics and particle physics research. DUNE will study questions pertaining to the preponderance of matter over antimatter in the early universe, the dynamics of supernovae, the subtleties of neutrino interaction physics, and a number of beyond the Standard Model topics accessible in a powerful neutrino beam. A critical component of the DUNE physics program involves the study of changes in a powerful beam of neutrinos, i.e., neutrino oscillations, as the neutrinos propagate a long distance. The experiment consists of a near detector, sited close to the source of the beam, and a far detector, sited along the beam at a large distance. This document, the DUNE Near Detector Conceptual Design Report (CDR), describes the design of the DUNE near detector and the science program that drives the design and technology choices. The goals and requirements underlying the design, along with projected performance are given. It serves as a starting point for a more detailed design that will be described in future documents
