Comparing Performance Of Aquaponics Systems Using Different Designs And Fish Feeds, Cody G. Willmore

Biology Theses, Dissertations, and Student Creative Activity

Future food production requires sustainable approaches that used both land and water resources efficiently, while remaining economically viable. One approach is aquaponics, the practice which combines hydroponics and aquaculture, as a sustainable food producing system. Aquaponic systems are unique, as the system can be designed to reuse and repurpose locally sourced materials and resources to meet individual needs. However, productivity of these systems can be inefficient or inconsistent, impacting the viability of aquaponics. The first objective of my study was to compare how system design between a do-it yourself reclaimed-materials aquaponic system and a prefabricated aquaponic setup affects water quality …

Intersectional Analysis Of Vaccination Inequity Among Individuals With Disabilities In The United States During The Covid-19 Pandemic, Philip Ndoki, Heba M. Athar, David O. Anderson

Journal of Social, Behavioral, and Health Sciences

We investigated how disability status, types, sociodemographic indicators, and reasons for not receiving vaccinations influenced COVID-19 vaccination rates among individuals with disabilities in the United States. Despite efforts, vaccination disparities persisted, necessitating a nuanced understanding of the barriers to vaccination. Using intersectionality theory and the social determinants of health framework, we examined the impact of marginalized identities and structural inequalities. Key questions included the association between disability status and vaccination uptake, differences among disability types moderated by sociodemographic factors, and the interaction between disability status and reasons for not vaccinating. We used Household Pulse Survey data from the U.S. Census …

Imaging Hallmarks Of Idiopathic Intracranial Hypertension And Insights Into Pathogenesis, Albalooshy Basimah, Scott Faro, Hsiangkuo Yuan, Kiran Talekar, Prabath Mondel, Enchao Qiu, Joga Chaganti

Department of Radiology Faculty Papers

Idiopathic Intracranial hypertension (IIH), also referred to as pseudotumor cerebri, is a term used to describe increased intracranial pressure in the absence of a known identifiable secondary cause. Despite advancements of neuroimaging techniques, imaging of the pathological underpinnings in the diagnosis of IIH has been limited. Although the causation of IIH has been ascribed to increased Cerebrospinal Fluid production and disordered drainage through the dural sinuses, new evidence shows that the glymphatic system which is an alternate pathway of drainage is likely to play a pivotal role. In this review, we address the pathophysiological underpinnings in the causation of IIH …

‘I Could Replicate The Situation Exactly The Same As I Do In Class’: Apprentice Lecturers Use Of A Learning Management System At An Irish University During And After Covid-19, Eleanor Attridge, Tom O'Mahony

Articles

While technology is playing a more critical role in learning, apprentice lecturers’ use of technology to support learning is under-researched. This qualitative study explores apprentice lecturers’ use and experience of a Learning Management System during and after COVID-19. Thematic analysis was used to make sense of the rich data, gathered using semi-structured interviews, from ten apprentice lecturers. The analysis revealed that technology use largely mirrored participants’ teacher-centric face-to-face methods. This approach did not sustain apprentice online engagement. Applying the theoretical framework, TPACK revealed that limited pedagogical expertise and, to a lesser extent, limited technological proficiency shaped participants’ approaches. Systemic constraints …

Woodchip-Based Permeable Reactive Barriers For Groundwater Nitrogen Removal: Design Optimization To Minimize Greenhouse Gas Release Informed By Experimental Studies And Reaction-Transport Modeling, Jing-An Lin Phd

Electronic Dissertations and Theses, 2010-current

Submarine groundwater discharge of legacy nitrogen can significantly contribute to coastal eutrophication. Permeable reactive barriers (PRBs) that intercept contaminated groundwater and provide a carbon source for microbially mediated denitrification are increasingly considered to remove nitrate before it reaches coastal surface waters. While woodchips have been shown to efficiently remove nitrate, open questions remain regarding the nitrogen removal performance of PRBs with different woodchip arrangements (trench-type vs column arrays), woodchip types (hardwoods vs softwoods) and the potential formation, release and fate of secondary byproducts, specifically greenhouse gases and dissolved iron. This dissertation aimed to address these knowledge gaps through a combination …

“We Built Our Plane As We Flew It”: Communicative Resilience In Nonprofit Organizing During The Pandemic, Evgeniya Pyatovskaya

USF Tampa Graduate Theses and Dissertations

This dissertation investigates how nonprofit organizations cultivate resilience through communication and practice during periods of disruption, focusing on the COVID-19 pandemic. Using a case study of Apex for Youth—a New York City-based nonprofit serving low-income Asian and immigrant youth—this research explores how organizational members co-constructed resilience in response to both the pandemic and rising anti-Asian hate.

All But Mud & Memories, Chase Lt Romero

LSU Master's Theses

All But Mud & Memories addresses the inevitability of erosion and land loss near my homeland of Algiers Point— locally known as The Point— through the perspective of locals and visitors, in addition to my own experience. Located near New Orleans across the Mississippi River, Algiers Point holds a community that shares a tender bond with the levee that protects their home and day-to-day interactions. Often in discussions of wetland events in Louisiana, the focus is on land and environmental losses rather than the surrounding culture. I provide a more community-centered narrative by expressing what’s to be lost if the …
