Florida Local Public Administrator Perspectives On Decentralized Wastewater Treatment, Jude Hagan

Honors Undergraduate Theses

Decentralized wastewater treatment (DWT) systems, such as onsite greywater recycling and septic systems, have been demonstrated to be a potentially more sustainable, cost-effective, and disaster-resilient alternative to traditional centralized systems by treating wastewater at or near the source. However, many barriers exist that have prevented the widespread implementation of DWT, such as public opposition, lack of resources, government regulations, public health concerns, and capital costs. In this study, local emergency managers, urban planners, and utility/wastewater managers in Florida were surveyed to determine their perceptions and levels of knowledge on DWT. The results of this study were inconclusive due to a …

Numerical Modeling Of Climate Change Impacts On Transportation Embankments, Amr Morsy, Mamata Sapkota, Emma Varela, Odalys Portillo

Mineta Transportation Institute

Embankments are essential components of transportation infrastructure, providing crucial support for long stretches of highways, railways, and other routes in California and around the world. Clay embankments are susceptible to weather-related deterioration processes that can gradually compromise their stability and, in some cases, lead to unexpected failures. Climate change, along with the associated shifts in weather patterns, is projected to adversely impact the weather-related deterioration processes, leading to exacerbated failures and/or shorter service life. Additionally, climate change is projected to increase the frequency of extreme precipitation events, leading to an increase in embankment failure potential. This study evaluated (1) the …

Analyzing The Role And Impact Of Energy Resources On The South China Sea Dispute, Adam Opp

Liberty University Journal of Statesmanship & Public Policy

The South China Sea is a critical but contested body of water that has been the source of much international debate and focus. The sea is a strategic maritime route and one of the most important waterways for regional and global trade. The South China Sea features rich natural resources such as fisheries and hydrocarbons, especially unknown amounts of oil and natural gas remaining untapped throughout the sea. Geological surveys estimate extremely lucrative quantities of oil and natural gas in the South China Sea, which drives the conflict, as nations with competing territorial claims seek to control not just the …

Addressing Climate Vulnerability And Policy Gaps Of Heat Waves In Upper Egypt: The Case Study Of Al-A’Qaab Village In Aswan, Eman Abdullah

Theses and Dissertations

Heatwaves are currently one of the most dangerous climate hazards globally. Egypt is experiencing an increase in the intensity and frequency of heatwaves, which affects health, economy, infrastructure, and the ecological system. Upper Egypt is one of the most vulnerable regions in Egypt to rising temperatures, particularly in Aswan Governorate. The risks of heat waves are increasing vulnerability among vulnerable groups, such as women and low-income individuals. However, there is a clear gap in protection policies against heat waves, along with a lack of studies examining the effects of heat waves on individuals in Aswan. Accordingly, this thesis aims to …

Abundance Strategies Should Promote Abundant Jobs In Distressed Places, Timothy J. Bartik

Upjohn Institute Policy Papers

A prominent recent policy debate is about “abundance policies”: policies to make it easier to build housing or infrastructure, deliver government services more quickly and more efficiently, and expedite the public funding of the most innovative and socially impactful research. In this essay, I argue that abundance advocates often mistakenly ignore or have a negative attitude toward “place-based policies.” These place-based policies would seek to increase employment rates, particularly in good jobs, in two types of distressed places that lack abundant job opportunities: distressed local labor markets and distressed neighborhoods. Both the goals and means of place-based policies fit into …

Constructing A State: Canals And The Transformation Of The Economy, Politics, And Finance In Nineteenth-Century New York, Youwei Xing

All Dissertations

This dissertation consists of three essays in economic history, unified by a focus on one of America's earliest transportation infrastructures, the canal system, in nineteenth-century New York. Each chapter explores a different aspect of the state's transformation: its economy, politics, and finance, each of which helped construct New York as the Empire State.

The first chapter studies the economic impact of canals on economic modernization from three aspects: sectoral transition, urbanization, and banking development. Contrary to much of the modern literature finds transportation infrastructure leads to decentralization, I find the opposite-evidence of centralization. Specially: (1) canal towns experienced a transition …

An Ambient Nox Reduction Reactor System With And Without Forced Air, Hamid Rahai, Rylan Moffit, Komal Gada, Jeremy Bonifacio

Mineta Transportation Institute

Ambient nitrogen oxide (NOX) is one of the main ingredients involved in the formation of ground-level ozone (smog), which contributes to global warming and the formation of particulates in the atmosphere and causes respiratory illnesses, especially in children, older adults, and people with lung diseases. Investigations on adding titanium dioxide (TiO2) nanoparticles to the paint used on concrete surfaces such as buildings and its potential in reducing ambient NOX concentration have provided opportunities for the research and development of methods for passive control and filtration of the ambient NOX. The present research used numerical geometrical optimization to identify an optimized …

Port drayage—trucking operations that move goods a short distance to and from ports—is a key part of freight logistics and the critical movement of goods in American communities. This project developed a microscopic energy consumption model using second-by-second activity data from 38 Class 8 diesel drayage trucks operating in Southern California. The model emulated FCEV operations and determined an average hydrogen fuel consumption of 0.15 kg/mile across 749 trips. This data informed a levelized cost of …

Wild Hogs In The Water: Contested Infrastructural Ecologies Of Reservoir Storage In Texas, Sayd Randle

Research Collection College of Integrative Studies

Reservoirs are developed to store water in reserve for future use. But once built, reservoir sites inevitably hold more than just water, often serving as a key habitat for a range of species. This paper examines how one such animal has transformed water storage facilities and nearby landscapes into contested ground in urbanising areas of Texas, USA. Living around the reservoirs, feral hogs complicate the process of urbanisation by degrading the stockpiled water and infrastructure at the storage sites themselves and by damaging private property throughout the surrounding landscape. Tracking local efforts to manage the hogs, the case study illustrates …

Assessing Vulnerabilities Associated With High-Risk Dams In Utah, Courtney Flint Dr., Michael Englert, Upmanu Lall Dr.

I-GUIDE Forum

Across the United States, the age of dam infrastructure presents a substantial threat. The potential for structural failure associated with these aging dams is exacerbated by increased climate uncertainty and the threat of dam overtopping due to extreme and prolonged precipitation events. These compound threats place downstream areas at pronounced risk. These downstream areas vary widely. Some are relatively free of vulnerable elements, while others have a complex mix of infrastructure, populations, and ecologically important elements. This paper highlights the risk situation associated with aging dams and hydroclimatic extremes, the methodological and geospatial challenges and opportunities associated with mapping the …
