Females of Color Who Have Served as Superintendent: Their Journeys to the Superintendency and Perceptions of the Office
The purpose of this study was to chronicle the journeys often females of color to the office of the superintendent, to document how they use the power of the office and to record their perceptions, as superintendent, of the office( s) they hold or have held. It provides an in-depth look at the females as people and as leaders. One premise of this study is that access to education and equity in employment opportunity are key factors in determining who may serve in the nation\u27s highest offices. Half of the respondents are the products of legally enforced segregation in their elementary school experiences and some were fully educated under a system of segregation. In spite of the inequity of education in the separate but equal schools, all of these women not only gained an education, but also achieved education at its highest level, the doctorate. Among other things, they identify familial support, a belief in a higher power and the ability to persevere as facilitators in reaching the highest teaching job in education The office of superintendent is much more than a profession to all of the women in this study; it is more of a mission. Most of the women expressed the desire to become academic leaders before they became superintendents. They prided themselves in having sat in many seats and used that knowledge to guide them in making decisions. Those who admittedly sought the superintendency as a primary goal surrounded themselves with others who had the technical knowledge that they lacked. When in office, they generally forged strong alliances and managed \u27\u27power with others, in contrast to the traditional model of top-down leadership, or the use of power over others. the superintendents interviewed believed strongly in what they were doing and all indicated that in spite of the challenges and the strife, they planned to All of remain and complete their mission. The ways in which they all wish to be remembered can be restated as individuals who served others and served them well
The uncertainties associated with sediment fingerprinting suspended and recently deposited fluvial sediment in the Nene river basin
The use of tracers within a sediment fingerprinting framework has become a commonly used technique for investigating the sources of fine sediment. However, uncertainties associated with tracer behaviour have been cited as major potential limitations to sediment fingerprinting methodologies. This paper aims to determine the differences between fingerprinting results derived using different groups of tracer properties and to determine the role of organic matter content, particle size, and within-source variability in tracer concentrations on the observed differences. A mean difference of 24.1% between the predicted contributions of sediment originating from channel banks was found when using different tracer groups. Mean differences between tracer group predictions were lower, at between 8% and 11%, when fingerprinting contributions from urban street dusts. Organic matter content and / or particle size showed little indication that they caused differences between tracer group predictions. The within-source variability in tracer concentrations and small contrasts between the tracer concentrations of different source groups were identified as probable causes of inherent uncertainty in the fingerprinting predictions. We determined that the ratio of the percentage difference between median tracer concentrations in the source groups and the average within-source tracer concentration coefficient of variation could indicate the likely uncertainty in model predictions prior to tracer use

Water insecurity and genderâbased violence: A global review of the evidence
We reviewed the existing literature documenting the association between water insecurity and gender-based violence to (1) describe the characteristics and contexts of available studies, and (2) identify and classify documented gender-based violence across domains of water insecurity (access, affordability, adequacy, reliability, and safety). 18 peer-reviewed articles mentioned associations between water insecurity and gender-based violence. All studies were conducted in sub-Saharan Africa and South Asia and were published in English. The most common manifestation of the relationship between water insecurity and gender-based violence was an increased risk of sexual and physical violence for women who walked long distances to access water. This was followed by intimate partner violence sparked by the inability to meet domestic obligations due to household water inadequacy. Despite these trends, the domains of water insecurity, and the types of violence experienced by women, were often intertwined. We conclude that there is a dearth of information assessing gender-based violence and water insecurity, especially in Latin America, North America, and Southeast Asia, and involving locally-based scholars. We suggest that the spectrum of what is considered âviolenceâ in relation to water insecurity be expanded and that scholars and practitioners adopt the term âgender-based water violenceâ to describe water-related stressors that are so extreme as to threaten human health and well-being, particularly that of women and girls. Finally, we encourage the development of cross-culturally validated measures of gender-based violence, which can be deployed in conjunction with standardized measures of water insecurity, to evaluate interventions that target these linked threats to global health
Water Insecurity, Self-reported Physical Health, and Objective Measures of Biological Health in the Peruvian Amazon
ObjectivesThis study examines the associations between water insecurity, self-reported physical health, and objective measures of biological health among 225 AwajĂșn adults (107 women; 118 men) living in the Peruvian Amazon, a âwater-abundantâ region.MethodsA survey, which included multiple measures of self-reported physical health, and objective measures of biological health such as blood pressure and nutritional and immune biomarkers.ResultsGreater water insecurity was associated with multiple measures of self-reported physical health, including higher incidence of reported diarrhea, nausea, back pain, headaches, chest pain, fatigue, dizziness, overall poor perceived health, and âbeing sick.â These symptoms align with the physical strain associated with water acquisition and with drinking contaminated water. A significant association between higher water insecurity and lower systolic blood pressure emerged, which may be linked to dehydration. None of the other biomarkers, including those for nutrition, infection, and stress were significantly associated with water insecurity scores.ConclusionsThese analyses add to the growing body of research examining the associations between water insecurity and health. Biocultural anthropologists are well-positioned to continue probing these connections. Future research will investigate relationships between measures of water insecurity and biomarkers for gastrointestinal infection and inflammation in water-scarce and water-abundant contexts

Clinical prediction models and the multiverse of madness
Background Each year, thousands of clinical prediction models are developed to make predictions (e.g. estimated risk) to inform individual diagnosis and prognosis in healthcare. However, most are not reliable for use in clinical practice.
Main body We discuss how the creation of a prediction model (e.g. using regression or machine learning methods) is dependent on the sample and size of data used to develop itâwere a different sample of the same size used from the same overarching population, the developed model could be very different even when the same model development methods are used. In other words, for each model created, there exists a multiverse of other potential models for that sample size and, crucially, an individualâs predicted value (e.g. estimated risk) may vary greatly across this multiverse. The more an individualâs prediction varies across the multiverse, the greater the instability. We show how small development datasets lead to more different models in the multiverse, often with vastly unstable individual predictions, and explain how this can be exposed by using bootstrapping and presenting instability plots. We recommend healthcare researchers seek to use large model development datasets to reduce instability concerns. This is especially important to ensure reliability across subgroups and improve model fairness in practice.
Conclusions Instability is concerning as an individualâs predicted value is used to guide their counselling, resource prioritisation, and clinical decision making. If different samples lead to different models with very different predictions for the same individual, then this should cast doubt into using a particular model for that individual. Therefore, visualising, quantifying and reporting the instability in individual-level predictions is essential when proposing a new model
