    Pretrial Mediation of Complex Scientific Cases: A Proposal to Reduce Jury and Judicial Confusion

    Get PDF
    This Note proposes pretrial mediation using scientist-mediators for complex scientific disputes. Complex scientific disputes reflect the inherent tension between law and science. This tension results in dissatisfaction among judges, juries, and scientists because of the uncertainties embraced by science, but eschewed by law. Pretrial mediation would address some of these uncertainties before they are introduced into the courtroom. In short, the proposed pretrial mediation should reduce jury confusion and provide judges with guidance to assess the admissibility of scientific evidence and expert opinions by eliminating and clarifying scientific issues

    Embracing a Competency-Based Specialty Curriculum for Community-Based Nursing Roles

    The Quad Council competencies for public health nursing (PHN) provide guidance in developing curricula at both the generalist and specialist level. However, these competencies are based on nursing roles in traditional public health agencies and community/public health is defined more broadly than official agency practice. The question arises as to whether community-based specialties require largely the same knowledge and skill set as PHN. The purpose of the competency cross-mapping project reported here was to (a) assess the intersection of the Quad Council competencies with four community-based specialties and (b) ensure the appropriateness of a Quad Council-based curriculum to prepare graduates across these four specialties (home health, occupational health, environmental health, and school nursing). This article details the multistep cross-mapping process, including validation with practice leaders. Results indicate strong alignment of community-based specialty competencies with Quad Council competencies. Community-based specialty-specific content that did not align well is identified, along with examples of didactic and clinical strategies to address gaps. This work indicates that a Quad Council-based curriculum is appropriate to prepare graduates in community-based specialties when attention to the specialty-specific competencies in the clinical setting is included. This work guides the development of a doctorate of nursing practice curriculum in PHN, encompassing the four additional community-based specialties

    ABSTRACT Objectives: This paper presents thoughts of practice leaders in the community/public health nursing (C/PHN) specialty on advanced nursing practice (ANP) and the necessary educational preparation for such practice. Design and Sample: Practice leaders were engaged in conversations specifically focused on the Doctor of Nursing Practice (DNP) as preparation for ANP in their specialties, and asked to consider the benefits of, and challenges to, this educational program. Measures and Results: The resulting remarks were then assessed for themes by the interviewers and these are presented along with thoughts on the future of education for ANP. Conclusion: Overall, there was much agreement among the practice leaders interviewed about the importance of a broad skill set for ANP in the specialty. However, the practice leaders interviewed here also identified the practical challenges involved in educating nurses at the DNP level in the C/PHN specialty, as well as some concerns about the definitions of ANP for the future

    Matching a Graduate Curriculum in Public/Community Health Nursing to Practice Competencies: The Rush University Experience

    Get PDF
    An evidence‐based approach to Public/Community Health Nursing (P/CHN) requires that P/CHN educators prepare practitioners with the relevant skills, attitudes, and knowledge. Such education should be competency‐based and have measurable outcomes to demonstrate student preparation. In 2003, the Quad Council competencies were developed to be applied at two levels of public health nursing practice: the staff nurse/generalist role and the manager/specialist/consultant role. This paper describes a process for evaluation and revision of a graduate curriculum to prepare Advanced Practice Clinical Nurse Specialists (CNS) in P/CHN, to ensure that the educational program addresses and develops knowledge and proficiency in all relevant competencies. This paper documents the process of integrating the competencies throughout the P/CHN graduate curriculum at varying levels, guiding students to achieve proficiency in each competency by the end of the program. Measurement of achievement in these competencies will be discussed, and examples provided. Advanced Practice Public Health Nurses educated via this competency‐based approach will be prepared to sit for national certification as a CNS in Public/Community Health, and to assume leadership roles in public health nursing

    Evidence on the Human Health Effects of Low-Level Methylmercury Exposure

    Get PDF
    Background: Methylmercury (MeHg) is a known neuro-toxicant. Emerging evidence indicates it may have adverse effects on the neuro-logic and other body systems at common low levels of exposure. Impacts of MeHg exposure could vary by individual susceptibility or be confounded by bene-ficial nutrients in fish containing MeHg. Despite its global relevance, synthesis of the available literature on low-level MeHg exposure has been limited

    Incorporating concepts of inequality and inequity into health benefits analysis

    BACKGROUND: Although environmental policy decisions are often based in part on both risk assessment information and environmental justice concerns, formalized approaches for addressing inequality or inequity when estimating the health benefits of pollution control have been lacking. Inequality indicators that fulfill basic axioms and agree with relevant definitions and concepts in health benefits analysis and environmental justice analysis can allow for quantitative examination of efficiency-equality tradeoffs in pollution control policies. METHODS: To develop appropriate inequality indicators for health benefits analysis, we provide relevant definitions from the fields of risk assessment and environmental justice and consider the implications. We evaluate axioms proposed in past studies of inequality indicators and develop additional axioms relevant to this context. We survey the literature on previous applications of inequality indicators and evaluate five candidate indicators in reference to our proposed axioms. We present an illustrative pollution control example to determine whether our selected indicators provide interpretable information. RESULTS AND CONCLUSIONS: We conclude that an inequality indicator for health benefits analysis should not decrease when risk is transferred from a low-risk to high-risk person, and that it should decrease when risk is transferred from a high-risk to low-risk person (Pigou-Dalton transfer principle), and that it should be able to have total inequality divided into its constituent parts (subgroup decomposability). We additionally propose that an ideal indicator should avoid value judgments about the relative importance of transfers at different percentiles of the risk distribution, incorporate health risk with evidence about differential susceptibility, include baseline distributions of risk, use appropriate geographic resolution and scope, and consider multiple competing policy alternatives. Given these criteria, we select the Atkinson index as the single indicator most appropriate for health benefits analysis, with other indicators useful for sensitivity analysis. Our illustrative pollution control example demonstrates how these indices can help a policy maker determine control strategies that are dominated from an efficiency and equality standpoint, those that are dominated for some but not all societal viewpoints on inequality averseness, and those that are on the optimal efficiency-equality frontier, allowing for more informed pollution control policies

    Cortisol, cognition and the ageing prefrontal cortex

    The structural and functional decline of the ageing human brain varies by brain region, cognitive function and individual. The underlying biological mechanisms are poorly understood. One potentially important mechanism is exposure to glucocorticoids (GCs; cortisol in humans); GC production is increasingly varied with age in humans, and chronic exposure to high levels is hypothesised to result in cognitive decline via cerebral remodelling. However, studies of GC exposure in humans are scarce and methodological differences confound cross-study comparison. Furthermore, there has been little focus on the effects of GCs on the frontal lobes and key white matter tracts in the ageing brain. This thesis therefore examines relationships among cortisol levels, structural brain measures and cognitive performance in 90 healthy, elderly community-dwelling males from the Lothian Birth Cohort 1936. Salivary cortisol samples characterised diurnal (morning and evening) and reactive profiles (before and after a cognitive test battery). Structural variables comprised Diffusion Tensor Imaging measures of major brain tracts and a novel manual parcellation method for the frontal lobes. The latter was based on a systematic review of current manual methods in the context of putative function and cytoarchitecture. Manual frontal lobe brain parcellation conferred greater spatial and volumetric accuracy when compared to both single- and multi-atlas parcellation at the lobar level. Cognitive ability was assessed via tests of general cognitive ability, and neuropsychological tests thought to show differential sensitivity to the integrity of frontal lobe sub-regions. The majority of, but not all frontal lobe test scores shared considerable overlap with general cognitive ability, and cognitive scores correlated most consistently with the volumes of the anterior cingulate. This is discussed in light of the diverse connective profile of the cingulate and a need to integrate information over more diffuse cognitive networks according to proposed de-differentiation or compensation in ageing. Individuals with higher morning, evening or pre-test cortisol levels showed consistently negative relationships with specific regional volumes and tract integrity. Participants whose cortisol levels increased between the start and end of cognitive testing showed selectively larger regional volumes and lower tract diffusivity (correlation magnitudes <.44). The significant relationships between cortisol levels and cognition indicated that flatter diurnal slopes or higher pre-test levels related to poorer test performance. In contrast, higher levels in the morning generally correlated with better scores (correlation magnitudes <.25). Interpretation of all findings was moderated by sensitivity to type I error, given the large number of comparisons conducted. Though there were limited candidates for mediation analysis, cortisol-function relationships were partially mediated by tract integrity (but not sub-regional frontal volumes) for memory and post-error slowing. This thesis offers a novel perspective on the complex interplay among glucocorticoids, cognition and the structure of the ageing brain. The findings suggest some role for cortisol exposure in determining age-related decline in complex cognition, mediated via brain structure
