Local Employment Growth, Migration, and Public Land Policy: Evidence from the Northwest Forest Plan
Debates over protecting public land reveal two views. Some argue protection reduces commodity production, reducing local employment and increasing out-migration. Others contend protection produces amenities that support job growth and attract migrants. We test these competing views for the Northwest Forest Plan (NWFP), which reallocated 11 million acres of federal land from timber production to protecting old-growth forest species. We find evidence that land protection directly reduced local employment growth and increased net migration. The total negative effect on employment was offset only slightly by positive migration-driven effects. Employment losses were concentrated in metropolitan counties, but percentage losses were higher in rural counties.amenities, employment growth, migration, Northwest Forest Plan, oldgrowth forests, public land management, Community/Rural/Urban Development, Land Economics/Use,
Indiana Clinical and Translational Sciences Institute Metrics
poster abstractThe Indiana Clinical and Translational Sciences Institute (Indiana CTSI) activities are designed to contribute to the achievement of NIH Strategic Goals for the Clinical and Translational Sciences Award program. The Indiana CTSI uses a Logic Model-based system of metrics to provide data to the NIH regarding Indiana CTSI accomplishments. The metrics address achievement of Specific Aims, number of investigators benefitting from Indiana CTSI resources, publications generated from Indiana CTSI-supported activities, and the awarding of pilot grant funds to support the acquisition of findings and data that may support applications for external funding. This poster shows the growth in Indiana CTSI accomplishments over the first three years of the CTSA grant. Conclusions: The Indiana CTSI has increased its contribution to the NIH strategic goals to advance the conduct of clinical and translational sciences through support of investigators, the contribution of new knowledge, and support for pilot grant activity

A measure of nature connectedness for children and adults: Validation, performance, and insights
With benefits to both human well-being and pro-nature conservation behaviors, nature connectedness is emerging as an important psychological construct for a sustainable future. The growing research and applied and policy-related interests require a straightforward measure of nature connectedness that is suitable for both children and adult populations. To establish the reliability of the new Nature Connection Index (NCI) three factor analyses were conducted. One was based on a large Monitor of Engagement with the Natural Environment (MENE) dataset for adults (n = 3568) with a replication from data sets collected online (n = 553), and a third used MENE data from children (n = 351). To validate the NCI as a measure for nature connectedness an online comparison study (n = 153) included the NCI alongside other established measures. The results showed that the NCI was a reliable and valid scale that offers a short, simple alternative to other measures of nature connectedness, particularly for populations including both children and adults, measured face to face or online. The utility of the NCI is also supported, with variations associated with various pro-environmental and pro-conservation behaviors observed, and importantly the NCI also revealed changes in nature connectedness across the lifespan.N/
Use of two-photon lithography with a negative resist and processing to realise cylindrical magnetic nanowires
Cylindrical magnetic nanowires have been shown to exhibit a vast array of fascinating 10 spin textures, including chiral domains, skyrmion tubes and topologically protected domain walls 11 that harbor Bloch points. Here we present a novel methodology that utilizes two-photon 12 lithography in order to realize tailored 3D porous templates upon prefabricated electrodes. 13 Electrochemical deposition is used to fill these porous templates, and reactive ion etching is used to 14 free the encased magnetic nanowires. The nanowires are found to have a diameter of 420nm, length 15 of 2.82m and surface roughness of 7.6nm. Magnetic force microscopy in an externally applied field 16 suggests a complex spiraling magnetization state, which demagnetizes via the production of 17 vortices of alternating chirality. Detailed micro-magnetic simulations confirm such a state and a 18 qualitative agreement is found with respect to the switching of experimental nanowires. 19 Surprisingly, simulations also indicate the presence of a Bloch point as a metastable state during the 20 switching process. Our work provides a new means to realize 3D magnetic nanowires of controlled 21 geometry and calculations suggest a further reduction in diameter to sub-200nm will be possible, 22 providing access to a regime of ultrafast domain wall motion
Solar-powered Water Purification and Community Development in Haiti\u27s Artibonite Valley
In May 2017, the Project Haiti team of two faculty and eleven students from Embry-Riddle Aeronautical University, Daytona Beach, Florida, working together with a professor and translator from the Universite d’Etat d’Haiti, designed and installed a solar-powered water purification system in the village of Drouin, Artibonite Department, Haiti. This region has been at the epicenter of the post-2010 cholera epidemic that has infected hundreds of thousands and killed many thousands. There has been no reliably safe drinking water in the region. The Haitian operators were empowered with ongoing maintenance and operation of the system, as well as the micro-business operations. Partnership with Haitians and the long-term partnering NGO (non-governmental organization) is a critical enabling aspect that improves sustainability of this community development effort
Seismic Response of Deep Soil Profiles in the New Madrid Seismic Zone
Geotechnical and geophysical investigations are being performed at a site which is located within 60 km of the epicenter of the 8.7 magnitude New Madrid February 7, 1812 earthquake. The exploration is being performed to determine the seismic response of the soil profile and to evaluate the liquefaction potential of the site. Permanent downhole instrumentation for seismic monitoring will be installed
Sustainable Grazing Management for Temporal and Spatial Variability in North Australian Rangelands–A Synthesis of the Latest Evidence and Recommendations
Rainfall variability is a major challenge to sustainable grazing management in northern Australia, with management often complicated further by large, spatially heterogeneous paddocks. This paper presents the latest grazing research and associated bio-economic modeling from northern Australia and assesses the extent to which current recommendations to manage for these issues are supported. Overall, stocking at around the safe long term carrying capacity will maintain land condition and maximize long term profitability. However, stocking rates should be varied in a risk-averse manner as pasture availability varies between years. Periodic wet season spelling is also essential to maintain pasture condition and allow recovery of overgrazed areas. Uneven grazing distributions can be partially managed through fencing, providing additional waters and in some cases patch burning, although the economics of infrastructure development are extremely context dependent. Overall, multipaddock grazing systems do not appear justified in northern Australia. Provided the key management principles outlined above are applied in an active, adaptive manner, acceptable economic and environmental outcomes will be achieved irrespective of the grazing system applied
