Mapping Flat, Deep, And Slow: On The 'Spirit Of Place' In New Cinema History, Jeffrey Klenotic

Faculty Publications

This essay engages in a creative, heuristic, and reflexive consideration of the ‘localities’ of cinema audiences by exploring New Cinema History as a place. New Cinema History is conceptualised as a place continually produced in and through its interactions with the heterogeneous multiplicities of situated audiences and experiences of cinema that form the topoi of its landscape of inquiry. In reflecting on how this placialised landscape has been and might be represented, I argue that New Cinema History’s ‘spirit of place’ is most productive when rendered within a ‘splatial’ framework that draws upon practices of flat, deep, and slow mapping …

Spatial And Temporal Determinants Associated With Eastern Equine Encephalitis Virus Activity In Florida, Kristi M. Miley

USF Tampa Graduate Theses and Dissertations

Eastern Equine Encephalitis virus (EEEV) is considered the most pathogenic mosquito-borne illness in the United States. Human mortality has been estimated to range between 35 to 75%, with horses experiencing mortality rates greater than 90%. A large number of EEEV cases occur in Florida. Though we have come a long way since the first human infection was identified in the 1930s, there is still much to learn regarding the virus’s ability to maintain transmission year-round in Florida.

Ecological Impacts Of Food Waste Digestate Management In An Agricultural Watershed, Shradha Shrestha

Theses

Globally, more than two billion tons of food are wasted each year, creating significant economic and environmental issues. Anaerobic digestion (AD), a process to convert organic waste to biogas, is a potential waste-to-energy alternative to landfilling wasted food (FW). Liquid digestate, a by-product of AD, is typically stored on-site in ponds prior to field application as a fertilizer, presenting risks of greenhouse gas (GHG) emissions and nutrient release to sensitive waterways. To assess this risk, we used a co-digestion (FW plus manure) facility and associated row-crop disposal system in an agricultural watershed in western New York, USA as a case …
