    Understanding Caregiver Factors Influencing Childhood Influenza Vaccination

    Get PDF
    Influenza is a contagious disease that affects approximately 30% to 40% of American children yearly, and all children 18 and under are recommended to be vaccinated. Through the use of a survey tool, 119 responses were collected about the factors that influence the decisions of caregivers whether or not to vaccinate their children against influenza. The knowledge generated from the survey may be used to formulate education programs to increase vaccination rates

    Anisotropic Stark Effect and Electric-Field Noise Suppression for Phosphorus Donor Qubits in Silicon

    We report the use of novel, capacitively terminated coplanar waveguide (CPW) resonators to measure the quadratic Stark shift of phosphorus donor qubits in Si. We confirm that valley repopulation leads to an anisotropic spin-orbit Stark shift depending on electric and magnetic field orientations relative to the Si crystal. By measuring the linear Stark effect, we estimate the effective electric field due to strain in our samples. We show that in the presence of this strain, electric-field sources of decoherence can be non-negligible. Using our measured values for the Stark shift, we predict magnetic fields for which the spin-orbit Stark effect cancels the hyperfine Stark effect, suppressing decoherence from electric-field noise. We discuss the limitations of these noise-suppression points due to random distributions of strain and propose a method for overcoming them

    Social impact measurement as an entrepreneurial process.

    Third sector organisations are growing in scale and scope, but little is known about how they measure their social value and report their achievements. This paper explores the process of social impact assessment in charities, voluntary organisations, and social enterprises. It looks at why organisations embark on social impact measurement; what guides their decisions about how to measure this impact, and how they use the results. It argues that these decisions are shaped by the objectives of the leadership and power relationships within organisations and, more importantly, with stakeholders outside the organisation. Impact measurement can be seen as a bureaucratic form of regulation or as a form of marketing for organisations with entrepreneurial skills. The lack of consistent approaches, and the range of assumptions that need to be made in any measurement process, provide organisations with ‘room to manoeuvre’ and a source of power to influence others. In this way, the process of measuring impact can been seen as a socially entrepreneurial process – a way to create opportunities and win scarce resources needed to make a social impact

    Social impact measurement and non-profit organisations: compliance, resistance, and promotion

    Get PDF
    Non-profit organisations are under increasing pressure to demonstrate their social impact. This paper examines the experience and behaviour of non-profit organisations in the UK in relation to a demand for impact evaluations. It shows that organisations both accept and resist control, and use evaluations for promotional purposes. External resource providers request organisations to present evidence on how resources are used and what organisations have achieved. However, non-profit organisations can also proactively use social impact measurement as a way of exerting control over their environment through using their discretion in deciding what to measure, how to measure and what to report. The analysis uses a combination of the concepts acceptance, rejection, compliance and strategic decoupling to distinguish different organisational responses to external demands for impact evaluation
