Using Low-Flow Sampling Data To Estimate Hydraulic Conductivity In Aquifers, Joy Kiefer

Masters Theses

Hydrogeologists sample wells to test aquifer water quality and use slug tests to estimate aquifer permeability. Robbins et al. (2009) proposed a more efficient way to obtain the goals of the two tests—the use of low-flow sampling and the use of the resulting flow rate and drawdown data to estimate aquifer hydraulic conductivity (K). The Robbins et al. method calculates K by using the slope of the best fit line from the graph of flow rate vs. drawdown for all low-flow pumping data collected at a well. When the method was applied to low-flow data from four Kalamazoo, MI, it …

Creating Appropriate Clinical Guidelines For The Bilingual Population With Acquired Brain Injuries, Sophia L. Pena

Dissertations

While there is a growing bilingual demographic in the United States, relatively little is known about treating this population should they experience a brain injury. This is a growing area of interest, as research has demonstrated that the acquisition of a second language promotes neuroplastic changes that then impact brain functioning pre- and post-brain-injury. Given bilingualism’s cognitive complexity, clinicians are left with challenges on how best to tailor treatment for brain-injured bilingual populations. Therefore, the focus of this review was to provide clinical recommendations to clinicians performing assessments with bilingual individuals with acquired brain injuries. The goal was for the …

Testing Methods Of Surficial Sinkhole Identification Using Remotely Sensed Data, Dane P. Brophy

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Nearly a quarter of all people rely on karst aquifers for drinking water. In the United States, the Safe Water Drinking Act requires a complete assessment of public water systems' vulnerabilities to contamination. As part of that assessment, watershed boundaries must be delineated, while recharge and supply locations identified. In the context of karst aquifers, surficial karst features, such as sinkholes, can act as a point source of direct recharge to karst aquifers and create vulnerabilities to critical drinking water sources. Historical methods of locating these features are inefficient and depend on basic field investigations, resulting in a clear need …

The Effects Of Bank Lobbying And Elections Surprises, Gregory Logan Tarbet

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper examines the stock market reaction to banks that lobby relative to banks that did not lobby in the period around the November 9, 2016, U.S. presidential election. Using three different methods of event studies to calculate the cumulative average return, we find that lobbying in banks has a meaningful relationship to an abnormal increase in those firm’s stock prices. Then we attempt to control for both the systemic importance and size of these institutions by performing cross-sectional regressions that include matched size, and the systemic nature of the banks. The results suggest that a heavily regulated industry such …

Census Tracts, Racial Separation, And The Landscape Of Higher Education, Aaron Scholl

College of Business: Dissertations, Theses, and Student Research

This dissertation centers on research at the intersection of labor, public, and urban economics. Chapter 1 details the role, process, and history of census tract delineation prior to each Decennial Census, and investigates short- and long-run implications of neighborhoods that receive further delineation, or become “split”. Using a difference-in-differences empirical design, I exploit Decennial Censuses from 1980 to 2010 to find that “split” census tracts increase in their proportion of Black residents and these effects persist decades. Further evidence suggests that the Low-Income Housing Tax Credit program may play a role in concentrating residents in areas with greater census tract …

Jailhouse Immigration Screening, Eisha Jain

Duke Law Journal

Within the past decade, U.S. interior immigration enforcement has shifted away from the street and into the jailhouse. The rationale behind jailhouse screening is to target enforcement efforts on those who fall within federal removal priorities. This Article shows how a program undertaken with the stated aim of targeting immigration enforcement has had precisely the opposite effect: it has massively expanded the reach of immigration enforcement and created extended carceral treatment within the criminal justice system based on suspected immigration status. This approach, in turn, leads to removals that lack adequate process, are inaccurate, or that reflect underlying racial biases …

Regulation And The Geography Of Inequality, Ganesh Sitaraman, Morgan Ricks, Christopher Serkin

Duke Law Journal

We live in an era of widening geographic inequality. Around the country, the spread between economically and culturally thriving places and those that are struggling has been increasing. “Superstar” cities like New York, San Francisco, Boston, and Atlanta continue to attract talent and grow, while the economies of other cities and rural areas are left behind. Troublingly, escalating geographic inequality in the United States has arrived hand in hand with serious economic, social, and political problems. Areas that are left behind have not only failed to keep up with their thriving peers; in many ways, they have stagnated and seen …
