The aim of this project has been to plot the locations of Community Supported Agriculture (CSA) drop-off sites in the Milwaukee Metro Area. Based on the eleven farm’s drop-off sites, a public Google Map has been created showing these drop-off points and the appropriately linked farms. In the focus of socioeconomic interests, these sites have been correlated with 2000 Census tract information dealing with percentages of White and Black neighborhoods,rates of bachelor’s degrees and areas where median income is below $10,000 dollars. Results show that drop-off sites are clustered in those areas where there is a higher concentration of White residents, in contrast to few or no drop-off sites in predominantly Black tracts sites. As well, the majority of locations lie in areas where there are high rates of Bachelor degrees, showing a potential connection with educational obtainment and dietary trends. Lastly,neighborhoods that have significant proportions of the population living below the poverty line have little or no dropoff sites in operation. Store front and traditional churches have been identified that may act as community sites for the establishment of new CSA locations in these disaffected areas.

Heterojunction nanowires were fabricated via a vapor-liquid-solid growth mechanism in a metal organic chemical vapor deposition system. The structure consisted of a n-type GaN:Si core surrounding by a distinct p-type AlGaN:Mg shell. Transmission electron microscopy revealed that the nanowires were free of extended defects. Photoluminescence measured a strong UV emission peak. Additionally, sources of mid-gap transitions are linked to surface states on the nanowire surface.
