    Critical Spirituality, Moral Philosophy, and Business Ethics

    Get PDF
    Critical ethics, according to David Boje, require a restoration of moral philosophy as a core value to the theory and practice of business ethics. Managerial business ethics often lack an answerability that challenges systemicity, which produces inhumane unethics. This essay supports answerability for the administered world of organization, power and politics. We join critical post-modern theorists in rejecting managerialism and the cultural industry. We advocate an ethics of responsibility that is drawn from moral philosophy and a free spirituality (by which we mean a trust in human potential, consciousness and human evolution). Just as ethics is often a grey area constantly being rethought, so too moral philosophy is being questioned and revised in post- modern theorizing. Disciplines relating to ethics are deconstructing the philosophical and ideological theories in order to move into the future. Critical theory is a work always and already partial in its progress. (Boje 2007) The assumptions of critical theory, as well as ethics and moral philosophy, therefore remain in a flow state. Each area of theory must function in a dialectical fashion - allowing for the unknown, the unseen and the unimaginable. Only in this state of mind can a truly creative co-mingling of unfinished ethics and evolving critical theory occur

    Harmonizing Product-Level GHG Accounting for Steel and Aluminum

    Greenhouse gas (GHG) accounting methods for steel and aluminum products have begun converging towards common standards within their respective industries in recent years. However, accounting methods for steel products and aluminum products are still not fully comparable with each other. If emissions are measured and allocated differently for these products, then these accounting differences have the potential to influence materials choices for manufacturers concerned about reducing their reported GHG footprint. Companies could therefore be motivated to make a choice between aluminum and steel according to emissions benefits that materialize from differences in accounting frameworks, but which do not actually exist in practice. These incentives will materialize for any substitutable materials which do not use fully comparable GHG accounting frameworks. Bringing product-level accounting methods for substitutable materials such as steel and aluminum into alignment with each other is therefore necessary to eliminate this gap. This study analyzes the major high-level differences between the International Aluminium Institute’s product-level guidance and cradle-to-gate product-level accounting in the steel industry, represented by a synthesis between the ResponsibleSteel International Standard and the Worldsteel Life Cycle Inventory Methodology

    Direct observation of Levy flight of holes in bulk n-InP

    We study the photoluminescence spectra excited at an edge side of n-InP slabs and observed from the broadside. In a moderately doped sample the intensity drops off as a power-law function of the distance from the excitation - up to several millimeters - with no change in the spectral shape.The hole distribution is described by a stationary Levy-flight process over more than two orders of magnitude in both the distance and hole concentration. For heavily-doped samples, the power law is truncated by free-carrier absorption. Our experiments are near-perfectly described by the Biberman-Holstein transport equation with parameters found from independent optical experiments.Comment: 4 pages, 3 figure
