Abstract:
... Winery owners in the Midwestern states of the United States have been working with each other and their state industry experts to improve the quality of their wines while also struggling to establish state and, at times, regional identities and overcome a widely-held perception that good wine is not made and cannot be made in the region. Drawing on a qualitative sociological study conducted over f ...

Abstract:
... The American presidency is evolving, and with it public expectations of how often and where the president should communicate. The rhetorical presidency, characterized by inclusive public appeals broadcast in a few media venues, has transitioned to a ubiquitous presidency wherein accessible, personal, and pluralistic communications are the norm. Despite these changes in communication style at the p ...

Abstract:
... Ulmus americana (American elm) was an important urban tree in North America prior to the introduction of the Dutch elm disease (Ophiostoma ulmi and O. novo-ulmi) pathogen in 1930. Subsequently, urban and community forests were devastated by the loss of the large canopies. Disease tolerant elms (Ulmus spp.) of various species were later developed; however, consumer acceptance of these trees was slo ...

Abstract:
... Crop yield can be affected by crop water use and vice versa, so when trying to simulate one or the other, it can be important that both are simulated well. In a prior inter-comparison among maize growth models, evapotranspiration (ET) predictions varied widely, but no observations of actual ET were available for comparison. Therefore, this follow-up study was initiated under the umbrella of AgMIP ...
