    The increasing involvement of philanthropists in education policy has contributed to the emergence of a dynamic sector of intermediary organizations (IOs), entities that serve a number of functions in school reform, including advocacy, consultation, policy design, alternative teacher and leadership preparation, and research. In recent years, many IOs have converged into coalitions that are pushing for incentivist educational policies like “parent trigger” laws, charter schools, vouchers, and teacher merit pay or sanctions often tied to value added metrics of teacher performance. This article draws on data from a mixed-methods, multiyear study of research use and dissemination. In this article, we examine the role of foundations in a broader advocacy coalition in Denver, Colorado, a key site for various incentivist reforms, including teacher pay-for-performance and charter schools. We find that IOs and their affiliated networks broker the production and use of research evidence, often targeting government and education policymakers, journalists, and increasingly, influential bloggers and social media communities. This brokering function positions foundations as the “hub” of research production, promotion, and utilization. La creciente participación de filántropos en el área de política educativa ha contribuido a la aparición de un sector dinámico de organizaciones intermediarias (OI), entidades que tienen un número de funciones en reformas escolares, incluyendo la promoción, consulta, diseño de políticas, formación docente alternativa y preparación de lideres y de investigación. En los últimos años, muchas organizaciones intermediarias han convergido en coaliciones que estimulan políticas educativas de incentivos como las leyes "gatillo", escuelas charter, vales educativos, y el pago por mérito docente o sanciones a menudo ligadas a métricas de valor añadido de desempeño de docentes. Este artículo se basa en datos recogidos durante varios años sobre el uso y difusión de la investigación de usando métodos mixtos. Este artículo, examina el papel de las fundaciones en una coalición de acción política en Denver, Colorado, un sitio clave para diversas reformas por incentivos, incluyendo el pago por rendimiento a los maestros y escuelas chárter. Encontramos que las OI y sus redes afiliadas intermediaban la producción y el uso de investigaciones, a menudo para orientar el gobierno y grupos de políticos, periodistas, y cada vez más, bloggers influyentes y las comunidades de redes sociales.

    Understanding the relation between Zika virus infection during pregnancy and adverse fetal, infant and child outcomes: a protocol for a systematic review and individual participant data meta-analysis of longitudinal studies of pregnant women and their infants and children

    IntroductionZika virus (ZIKV) infection during pregnancy is a known cause of microcephaly and other congenital and developmental anomalies. In the absence of a ZIKV vaccine or prophylactics, principal investigators (PIs) and international leaders in ZIKV research have formed the ZIKV Individual Participant Data (IPD) Consortium to identify, collect and synthesise IPD from longitudinal studies of pregnant women that measure ZIKV infection during pregnancy and fetal, infant or child outcomes.Methods and analysisWe will identify eligible studies through the ZIKV IPD Consortium membership and a systematic review and invite study PIs to participate in the IPD meta-analysis (IPD-MA). We will use the combined dataset to estimate the relative and absolute risk of congenital Zika syndrome (CZS), including microcephaly and late symptomatic congenital infections; identify and explore sources of heterogeneity in those estimates and develop and validate a risk prediction model to identify the pregnancies at the highest risk of CZS or adverse developmental outcomes. The variable accuracy of diagnostic assays and differences in exposure and outcome definitions means that included studies will have a higher level of systematic variability, a component of measurement error, than an IPD-MA of studies of an established pathogen. We will use expert testimony, existing internal and external diagnostic accuracy validation studies and laboratory external quality assessments to inform the distribution of measurement error in our models. We will apply both Bayesian and frequentist methods to directly account for these and other sources of uncertainty.Ethics and disseminationThe IPD-MA was deemed exempt from ethical review. We will convene a group of patient advocates to evaluate the ethical implications and utility of the risk stratification tool. Findings from these analyses will be shared via national and international conferences and through publication in open access, peer-reviewed journals.Trial registration numberPROSPERO International prospective register of systematic reviews (CRD42017068915).</jats:sec

    Evidence synthesis to inform model-based cost-effectiveness evaluations of diagnostic tests: a methodological systematic review of health technology assessments

    Background: Evaluations of diagnostic tests are challenging because of the indirect nature of their impact on patient outcomes. Model-based health economic evaluations of tests allow different types of evidence from various sources to be incorporated and enable cost-effectiveness estimates to be made beyond the duration of available study data. To parameterize a health-economic model fully, all the ways a test impacts on patient health must be quantified, including but not limited to diagnostic test accuracy. Methods: We assessed all UK NIHR HTA reports published May 2009-July 2015. Reports were included if they evaluated a diagnostic test, included a model-based health economic evaluation and included a systematic review and meta-analysis of test accuracy. From each eligible report we extracted information on the following topics: 1) what evidence aside from test accuracy was searched for and synthesised, 2) which methods were used to synthesise test accuracy evidence and how did the results inform the economic model, 3) how/whether threshold effects were explored, 4) how the potential dependency between multiple tests in a pathway was accounted for, and 5) for evaluations of tests targeted at the primary care setting, how evidence from differing healthcare settings was incorporated. Results: The bivariate or HSROC model was implemented in 20/22 reports that met all inclusion criteria. Test accuracy data for health economic modelling was obtained from meta-analyses completely in four reports, partially in fourteen reports and not at all in four reports. Only 2/7 reports that used a quantitative test gave clear threshold recommendations. All 22 reports explored the effect of uncertainty in accuracy parameters but most of those that used multiple tests did not allow for dependence between test results. 7/22 tests were potentially suitable for primary care but the majority found limited evidence on test accuracy in primary care settings. Conclusions: The uptake of appropriate meta-analysis methods for synthesising evidence on diagnostic test accuracy in UK NIHR HTAs has improved in recent years. Future research should focus on other evidence requirements for cost-effectiveness assessment, threshold effects for quantitative tests and the impact of multiple diagnostic tests

    The Politics of Fair and Affordable Housing in Metropolitan Atlanta: Challenges for Educational Opportunity

    No full text
    This qualitative case study considers the politics of the coalitions that emerged to address fair and affordable housing in the Atlanta metropolitan area between 2017 and 2020 and the connections or barriers they identified to educational opportunity. It applies regional, civic capacity, and social construction of policy frameworks to explore in which arenas the two issue areas of housing and education have been linked by policymakers, and by selected civic entities, non-profit organizations, and philanthropies. The case draws on demographic data, interviews, and documents in the analysis of the barriers to, and possibilities for, coordination of housing and education policy instruments to promote educational opportunity in the region. The author found that the majority of efforts to bridge the two policy areas were developed and led by non-profit actors, and mostly took the form of place-based interventions rather than mobility programs.&nbsp; Implications of these findings for policy design are discussed
