Abstract:
... The 2020 presidential race started in Iowa, like it has since 1972. The slate of candidates was the most diverse ever and included six women. This study examines the relationship between candidates’ gender, image, and support among Iowa voters. Iowans have access to candidates that other voters do not, so their perceptions provide unique insight into the construction of candidate images ...

There is an ongoing need to increase our understanding of the sources and timing of stream nitrate loads across agricultural watersheds in Iowa as water quality improvement strategies are implemented. The goal of this study was to model the relationship between nitrate load and the two components of streamflow (i.e., baseflow and stormflow) to quantify in-stream nitrate patterns and develop a new ...

Winter storms have been reported as the second-most frequent catastrophe in the Midwest of the United States and can create non-negligible impacts on farming communities that highly rely on climatic-sensitive resources and activities. However, few studies have attempted to assess the vulnerability to winter storms in rural contexts. Focusing on all counties in Iowa, US, as the study area ...

Using data on a sample of small Iowa towns consistently collected over two decades, we investigate how agglomeration economies, social capital, human capital, local fiscal policy, and natural amenities affect new firm entry. We find that human capital and agglomeration are more conducive to new firm entry than are natural amenities, local fiscal policy, or social capital. The impact of local ...
