    College of occupational therapists: Position paper on the way ahead for research, education and practice in mental health

    Get PDF
    The future of occupational therapy in mental health has been a topic of reflection and debate. The Education and Research Board (now the Education and Practice Board) of the College of Occupational Therapists created a Working Group to develop a position paper on the way ahead for research, education and practice in mental health. Following consultation, the Working Group reviewed literature, examined current research and surveyed practitioners, managers and educators. From these findings, recommendations have been made which will lead to a firmer evidence base for the practice of occupational therapy in mental health, leading to a more effective use of the expertise of occupational therapists and an improved service for users

    Shareholder Engagement and Chevron’s Policy 520 on Human Rights: The Role Played by the United States Jesuit Conference’s “National Jesuit Committee on Investment Responsibility”

    Get PDF
    Purpose To demonstrate how the Society of Jesus (Jesuits) in the United States through the “National Jesuit Committee on Investment Responsibility” played a significant role as a socially conscious institutional and religious investor in influencing Chevron’s Human Rights Policy 520 and to analyze the factors that contributed to a successful shareholder engagement with the company. Methodology/approach Case study based on firsthand information. Findings Our conclusion offers support for Allen et al.’s (2012) conclusion of legitimacy (credibility) being the dominant force in a successful engagement. We found that coalition-building is a significant moderating variable in increasing shareholder salience. This finding contradicts the study by Gifford (2010). Originality/value of chapter The chapter is based on the actual process of shareholder engagement with Chevron Corporation that led to the human rights policy and is written mainly based on firsthand information

    Computation of full-coverage film-cooled airfoil temperatures by two methods and comparison with high heat flux data

    Get PDF
    Two methods were used to calculate the heat flux to full-coverage film cooled airfoils and, subsequently, the airfoil wall temperatures. The calculated wall temperatures were compared to measured temperatures obtained in the Hot Section Facility operating at real engine conditions. Gas temperatures and pressures up to 1900 K and 18 atm with a Reynolds number up to 1.9 million were investigated. Heat flux was calculated by the convective heat transfer coefficient adiabatic wall method and by the superposition method which incorporates the film injection effects in the heat transfer coefficient. The results of the comparison indicate the first method can predict the experimental data reasonably well. However, superposition overpredicted the heat flux to the airfoil without a significant modification of the turbulent Prandtl number. The results suggest that additional research is required to model the physics of full-coverage film cooling where there is significant temperature/density differences between the gas and the coolant

    In our experiment, we found that the resistance of vacuum-dried λ\lambda-DNA exceeds 1014Ω10^{14} \Omega at 295 K. Bechhoefer and Sen have raised a number of objections to our conclusion. We provide counter arguments to support our original conclusion.Comment: 1 page reply to comment, 1 figur
