Determination of accurate baseline representation for three Central Iowa watersheds within a HAWQS-based SWAT analyses.

Improving food systems to address food insecurity and minimize environmental impacts is still a challenge in the 21st century. Ecohydrological models are a key tool for accurate system representation and impact measurement. We used a multi-phase testing approach to represent baseline hydrologic conditions across three agricultural basins that drain parts of north central and central Iowa, U.

Iowa Urban FEWS: Integrating Social and Biophysical Models for Exploration of Urban Food, Energy, and Water Systems.

Most people in the world live in urban areas, and their high population densities, heavy reliance on external sources of food, energy, and water, and disproportionately large waste production result in severe and cumulative negative environmental effects. Integrated study of urban areas requires a system-of-systems analytical framework that includes modeling with social and biophysical data. We describe preliminary work toward an integrated urban food-energy-water systems (FEWS) analysis using co-simulation for assessment of current and future conditions, with an emphasis on local (urban and urban-adjacent) food production.

Raising the Awareness of Undergraduate Nurses to the Psychosocial Impact of Living with Cancer: A Consumer Engagement in Teaching Initiative.

This article reflects on the development and implementation of a consumer engagement in teaching initiative by the authors. The authors highlight the challenges of engaging undergraduate nursing students on the psychosocial aspects of living with cancer and other chronic illnesses when students have very limited personal and professional experiences to draw on. The authors discuss how they have responded to these challenges by integrating the voices of consumers into their classrooms.

Biodiversity conservation in local planning.

Local land-use policy is increasingly being recognized as fundamental to biodiversity conservation in the United States. Many planners and conservation scientists have called for broader use of planning and regulatory tools to support the conservation of biodiversity at local scales. Yet little is known about the pervasiveness of these practices.

Valuation of open space and conservation features in residential subdivisions.

Conservation subdivision design has been promoted as a way to protect ecologically sensitive areas while maintaining housing densities comparable to standard subdivisions, but many developers and planners question the appeal of conservation design to consumers. This study was conducted to compare economic aspects of conservation subdivision design to standard subdivision design in the midwestern United States. Three methods were used to determine the value homebuyers have for embedded conservation features in residential areas: transactional analyses (to indicate the value homebuyers have expressed for such features in the past); hedonic analyses (to determine the proportion of present value of homes attributable to such features); and contingent valuation (to examine willingness to pay according to homebuyers' preferred features, an indicator of potential future investment).

Acute myocardial infarction related to methylphenidate for adult attention deficit disorder.

Adult Attention Deficit Disorder is increasingly diagnosed and treated. Psychostimulant medications, such as methylphenidate, are commonly prescribed for this condition, but the long-term safety of such medications in an adult population is unknown at present. Because these medications are closely related to amphetamines, it is expected that toxic side effects would be similar.

Yersinia pestis TonB: role in iron, heme, and hemoprotein utilization.

In Yersinia pestis, the siderophore-dependent yersiniabactin (Ybt) iron transport system and heme transport system (Hmu) have putative TonB-dependent outer membrane receptors. Here we demonstrate that hemin uptake and iron utilization from Ybt are TonB dependent. However, the Yfe iron and manganese transport system does not require TonB.
