    A re-examination of the cultural resistance orthodoxies within scholarly open access communication

    This paper presents a critical re-consideration of the problems in achieving a greater embrace of the praxis of open access (OA) to research publications within the UK academy. It offers an ideological critique of the underlying subversion of scholarly communication by an industrialised publishing sector. It also considers the ideological and financial drivers that have caused the emergence of an open access to research publications movement. Through examining this developing open access paradigm, it problematises aspects of the UK academy's reluctance to engage. While examining academics’ imperative to disseminate research, through exploring the legacy publication model, it proposes that that the higher education policy landscape must also be accounted for, when considering engagement barriers. Hence, the paper concludes that the conditioning of academics by a neoliberal policy-saturated environment likely contributes to their reticence to embrace the praxis

    Stress field orientation controls on fault leakage at a natural CO2 reservoir

    Travertine deposits present above the St. Johns Dome natural CO2 reservoir in Arizona, USA, document a long (> 400 kyr) history of surface leakage of CO2 from a subsurface reservoir. These deposits are concentrated along surface traces of faults, implying that there has been a structural control on the migration pathway of CO2-rich fluids. Here, we combine slip tendency and fracture stability to analyse the geomechanical stability of the reservoir-bounding Coyote Wash Fault for three different stress fields and two interpreted fault rock types to predict areas with high leakage risks.We find that these areas coincide with the travertine deposits on the surface, indicating that high-permeability pathways as a result of critically stressed fracture networks exist in both a fault damage zone and around a fault tip. We conclude that these structural features control leakage. Importantly, we find that even without in situ stress field data, the known leakage points can be predicted using geomechanical analyses, despite the unconstrained tectonic setting. Whilst acquiring high-quality stress field data for secure subsurface CO2 or energy storage remains critical, we shown that a firstorder assessment of leakage risks during site selection can be made with limited stress field knowledge

    Inter-sourcing: IT Solutions With University Partners

    Get PDF
    Managers are currently dealing with a variety of sourcing decisions regarding information technology (IT) projects. Reduction in labor costs is the primary driver for outsourcing and offshoring initiatives (e.g. Klaas, McClendon and Gainey, 1999; Lacity, Willcocks, and Feeny, 1996). However, the challenges posed by these solutions can be reduced, or possibly eliminated, through a novel and innovative collaboration approach called ‘inter-sourcing’. This paper defines what is meant by inter-sourcing, and identifies benefits and challenges associated with this new approach. This “work in progress” outlines the preliminary development of this exploratory project and the qualitative methodology that will be used to investigate the topic in depth. If accepted for the MWAIS program, the authors will share updated findings from interviews and anecdotal evidence of successful projects resulting from inter-sourcing alliances

    The impact of prescribed psychotropics on youth

    Many psychotropics prescribed to children are unlicensed or off-label. This article uses the two most prescribed psychotropics (MPH and SSRIs) to illustrate various concerns about their impact on youth. Many mental illnesses begin in childhood or early adulthood, warranting a treatment of some kind. However, commentators have argued that prescribing is influenced by five myths: (1) children are little adults; (2) children have no reason to develop depression or anxiety; (3) psychiatric disorders are the same across adults and children; (3) children can be prescribed lower doses of the same drug; (5) drugs are preferable to alternative treatments and are more successful. Several lines of evidence suggest that these are incorrect assumptions. We update readers with recent research in relation to these myths, concluding that researchers should clarify child/adult differences for psychotropics, attend to the growth of "cosmetic" use of psychotropics in children and adolescents, and address concerns about the diagnostic validity of mental illness in the current DSM classification system

    The Influence of Water-rock Reactions and O Isotope Exchange with CO2 on Water Stable Isotope Composition of CO2 Springs in SE Australia

    Get PDF
    Monitoring injected CO2 in CCS sites using oxygen isotopes of water has been demonstrated in field and laboratory experiments. Here, we examine natural CO2-rich springs in the Daylesford-Hepburn region, South East Australia, which show water 18O depletion compared to local precipitation. Geochemical modelling shows that water-rock reactions are unlikely to have a significant effect on the observed δ18O values, which can only be explained by isotopic exchange with CO2. The water δ18O shift can be used for monitoring CO2 impact on shallow groundwater aquifers, provided that there is sufficient CO2 and distinction between water and CO2 δ18O values exists
