Matrix Interpretations And Tools For Investigating Even Functionals, Benjamin Stringer

Theses and Dissertations--Computer Science

Even functionals are a set of polynomials evaluated on the terms of hollow symmetric matrices. Their properties lend themselves to applications such as counting subgraph embeddings in generic (weighted or unweighted) host graphs and computing moments of binary quadratic forms, which occur in combinatorial optimization. This research focuses primarily on counting subgraph embeddings, which is traditionally accomplished with brute-force algorithms or algorithms curated for special types of graphs. Even functionals provide a method for counting subgraphs algebraically in time proportional to matrix multiplication and is not restricted to particular graph types. Counting subgraph embeddings can be accomplished by evaluating a …

Image Geo-Localization With Cross-Attention, Connor Greenwell

Theses and Dissertations--Computer Science

The problem of estimating the location from which un-geotagged photographs were captured has been well studied by the computer vision community in recent years. The central proposal of this thesis is to define a common framework within which existing approaches can be constructed and evaluated, and to introduce a new method under this framework which uses cross-attention between the query image and a database of satellite imagery with known geotags. Our experiments fit within three broad categories: 1) evaluating the ability of image localization approaches to generalize to unseen regions; 2) examining performance changes under various reference database resolutions, scales, …

An Automated Framework To Debug System-Level Concurrency Failures, Tarannum Shaila Zaman

Theses and Dissertations--Computer Science

The ever-increasing parallelism in computer systems has made software more prone to concurrency failures, causing problems during both pre- and post-development. Debugging concurrent programs is difficult because of the non-deterministic behavior and the specific sequences of interleaving in the execution flow. Debugging is a technique where programmers reproduce the bug, identify the root cause, and then take necessary steps to remove the bug from the system. The failure information may come from the bug reports of the testing phase or the production runs. In both cases, there should be steps taken to reproduce and localize the failure. However, reproducing and …

We Can Still Feed Ourselves: Food Sovereignty, Aid, Sickness, And Health In Eastern Kentucky, Annie Koempel

Theses and Dissertations--Anthropology

Over forty percent of eastern Kentucky residents are classified as obese. From a biomedical perspective, obesity is linked to a range of chronic diseases, including heart disease, diabetes, and high blood pressure and is caused by particular lifestyle behaviors that lead to an increase in calorie consumption and decrease in calorie expenditure. However, these links – individual behavior leads to obesity which leads to chronic disease - do not take into account a wide range of personal, social, environmental, political, and economic conditions. In addition to the assumptions of what it means to become and be obese, Kentucky is regularly …

Development With Identity Or Commodities With Identity? Lenca Craftswomen, Honduras' Cultural Identity Politics, And Global Economies Of Culture, Ana Hasemann Lara

Theses and Dissertations--Anthropology

Across Latin America ‘development with identity’ schemes are currently widely promoted by multilateral and aid organizations; schemes based on the commercialization of heritage, which increasingly focus on impoverished ethnic minorities. As part of this trend, the Honduran state’s discourse on cultural diversity reinforces the ‘heritage-making’ (patrimonialización) of cultural minorities, their identities, and livelihoods—particularly indígena women, under the auspices of multiculturalism. However, the on-the-ground reality for indigenous Lenca communities, specifically Lenca craftswomen, participating in such initiatives, remains with some of the highest indices of poverty and vulnerability in the country. Hence, the conditions under which ‘development with identity’ benefits local communities, …

An Investigation Of Hhv6'S Impact On The Cognitive Progression And Microglial Changes In An Alzheimer's Disease Cohort, Charles E. Seaks

Theses and Dissertations--Physiology

The role of herpesviruses and, more specifically, HHV6 in the development of Alzheimer’s disease (AD) and associated cognitive decline is still being investigated. High ubiquity and prevalence in the population have led to a high degree of skepticism about HHV6 as a potential contributor to cognitive decline and dementias. However, recent evidence related to another herpesvirus, herpes simplex virus 1, suggests that reactivation, not carriage, of the virus may be the key factor to explain the dissonance between the virus’ ubiquity and contributions to dementias. With that in mind, we set out to assess cases from the Sanders-Brown Center on …

A Study Of The Improvement Of Weighting Scheme Using Administrative Data In A Panel Data, Sanggi Lee

MPA/MPP/MPFM Capstone Projects

This paper contains a problem that has been studied a lot in the household panel survey, that is, the contents of how to give initial weights to non-sample household members when they enter the sample household. In order to assign an initial weight to an object, information on its sampling probability is required, but it is difficult to obtain the first wave information for non-sampled household members. So, as a solution to this, the shared weights method and modeling method were studied and applied to the actual major household panel surveys. However, the data used in this paper is a …

Broadband Development In Lexington: A Study Of Access And Equity, Alex Sergent

MPA/MPP/MPFM Capstone Projects

Broadband equity is at the forefront of today’s issues. Those that have the ability to access the internet regularly from home are given an opportunity to participate in countless social, work, and learning opportunities that those without access must forgo. It is difficult to determine where broadband infrastructure fails. Through this study of Lexington-Fayette Urban County, it was found that connection within Urban Service Boundaries is on par with national goals, while rural areas are left out. This paper contains a descriptive analysis of the overall broadband access equity of Lexington-Fayette county.

Defunding The Police: True Police Reform Or Just Political Smoke And Mirrors? A Look At The City Of Camden, New Jersey And Its Approach To Police Reform, Anitra Austin

MPA/MPP/MPFM Capstone Projects

The summer of 2020 brought police brutality to the forefront of society. The deaths of Breonna Taylor and George Floyd at the hands of police officers ignited a firestorm of social justice movements. Black Lives Matter and other social justice organizations were calling for cities around the country to defund their police departments as a strategy for police reform. This strategy was largely unprecedented, and highly controversial. There was a lack of understanding of what defunding the police actually meant, as it seemed to mean different things to different people. The subtle suggestions of defunding the police quickly turned to …

An Analysis Of Krs 123.487 And The Motor Vehicle Tax Rates Levied Among Special Districts In Kentucky, Beth Atkinson

MPA/MPP/MPFM Capstone Projects

Kentucky Revised Statute 132.487 sets forth limitations on the motor vehicle tax rate, which can be levied by the state, counties, cities, and special taxing districts. According to the statute, the rate is formulated on a January 1, 1983 date without exception. However, a lack of oversight and understanding of KRS 132.487 has created problems among counties, cities, and special districts in Kentucky. In some cases, this has led to the adoption of tax rates which violate the statute and should be investigated and addressed by the legislature. This research suggests that non-compliance with KRS 132.487 is more prevalent among …

Merged Government: Is This An Option For Bowling Green And Warren County, Ky Governments?, Alice Williams

MPA/MPP/MPFM Capstone Projects

In recent history, the most common attempt at reorganization of government in a metropolitan area is the city-county consolidation model. With limited government resources, elected officials along with community members look to this model to make the best use of those resources. “Applied to local government, the term ‘‘consolidation’’ is generally understood to mean the structural merging of two or more governments into one. When a city and county consolidate, a new and different form of local government is created that has elements of both city and county government but is neither.” (Martin, 2011) There are both benefits and problems …

Kentucky’S K-12 Public School Spending And Its Relationship To Enrollment Percentages Of Students With Limited English Proficiency And Students Eligible For The Free And Reduced-Price Lunch Program, Christine Tarne

MPA/MPP/MPFM Capstone Projects

Public school funding formulas vary broadly between states in both the levels of funding and the mechanisms through which funding is distributed. Most states provide targeted funding for student populations that need supplemental resources, including low-income and limited English proficiency student populations, as does the Federal Elementary and Secondary Education Act (ESEA). In the past, a lack of school level enrollment and financial data made it difficult to determine whether funding provided to local education agencies has been equitably distributed to the schools with whom they are affiliated. The 2015 Federal Every Student Succeeds Act requires that school-level enrollment and …

Meeting Transfer Students Where They Are: A New Organizational Approach To Transfer Student Communication, Support, And Recruitment, Daniel Wright

Theses and Dissertations--Educational Leadership Studies

Transfer students have long played a significant role in the growth and diversity of colleges and universities. Recent research points to a continuous decline in enrollment over the coming decade (Kelderman, Gardner, & Conley, 2019), and as tuition costs continue to increase and enrollment numbers decrease, institutions of higher education have begun turning to transfer students to fill their lecture halls and football stadiums. A key variable in higher education’s transfer recruitment blind spot is a fundamental lack of understanding of the structural and organizational changes needed to both attract and retain these non-traditional students (Tobolowsky & Cox, 2012).
