Multidecadal Pre- And Post-Collapse Dynamics Of The Northern Larsen Ice Shelf, Shujie Wang, Hongxing Liu, Richard B. Alley, Kenneth Jezek, Patrick Alexander, Karen E. Alley, Zhengrui Huang, Lei Wang

Faculty Publications

Rapid retreat of Antarctic ice shelves in a warmer climate remains challenging to predict, contributing to uncertainties in projections of sea level rise. The collapse of the Larsen B Ice Shelf on the Antarctic Peninsula in 2002 was perhaps the most dramatic example of ice shelf retreat on record. Despite a general consensus that regional climate warming is associated with ice shelf collapse, knowledge of the precise details leading to and following collapse is limited. Here we examine a comprehensive set of satellite observations, modeling experiments, and climate reanalysis data to elucidate calving behavior, flow dynamics, and mechanical conditions of …

Assessing The Utility Of High-Throughput Phenotyping For Ecological Applications, Annabree Corlew

Honors Theses

A phenotype describes the expressed traits of an organism. These traits can provide insight into interactions between an organism and its environment, making them a key focus of ecological research. But the process of phenotyping traits can be tedious to collect for large-scale experiments. High-throughput phenotyping software has the ability to speed up the phenotyping process by allowing multiple traits to be phenotyped at once. However, the utility of this relatively new and continually developing computational tool is still being assessed, especially beyond applications focused on agricultural crops and grasses. I investigated the accuracy and efficiency of the open-access high-throughput …

Christians And/As Liberals?, Steven D. Smith

Notre Dame Law Review

Christianity and liberalism were made to fit each other, like hand and glove. According to some interpretations, anyway. Liberal constitutionalism, with its commitments to freedom and equal human dignity, is the political system that reflects and embodies Christian commitments; and the constitutional legal order that accompanies liberalism, centrally including legally enforced rights of religious freedom, is the mode of government that best permits Christians to live in accordance with their faith in a fallen and deviant world. Thus, a couple of decades ago, Robert Kraynak reported that “[a]lmost all churches and theologians now believe that the form of government most …

Analyzing Sea Level Rise Adaptation And Mitigation Strategies In Louisiana And The Netherlands, Jonah Mcdowell

Department of Environmental Studies: Undergraduate Student Theses

Sea level rise is an increasingly dangerous threat. As a byproduct of climate change, this is an issue that has the potential to impact countless people, animals, and ecosystems across the globe. As sea level rise continues to worsen, it is imperative that coastal communities develop their own strategies and plans to combat this problem. This study focuses on two areas, the state of Louisiana and the country of the Netherlands, and studies how they have responded to this problem. These locations were chosen because sea level rise is proportionally more severe at these two locations compared to other areas …

The Battle Of The Narrative In Jones V. Mississippi: Consideration Of Youth “In Name Only”, Stevie Leahy

Mercer Law Review

Juvenile sentencing within the United States is but one illustration of how the legal system reinforces the marginalization of populations that have been historically underinvested and underrepresented. Throughout the past century, the macro-narrative on sentencing has fluctuated nationally, as well as within individual states, with the reasoning used to justify decisions sliding between the conflicting lenses of rehabilitation and punishment. This has necessarily impacted the micro-narrative—the way that an individual’s story is considered and weighed (or ignored) within sentencing. There are endless factors that affect outcomes in sentencing: class, race and or ethnicity, gender, and access to counsel are just …

Plasticity Of Sorghum Biomass And Inflorescence Traits In Response To Nitrogen Application, Kyle M. Linders

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Nitrogen is an essential nutrient required for growth and development in plants. Insufficient nitrogen availability can reduce vegetative growth and grain yield. However, nitrogen is a costly input for farmers, is energy intensive to manufacture, and runoff of excess nitrogen fertilizer impacts water quality. Compared to its close relative, maize, sorghum has much greater resilience to nitrogen and water deficit, and heat stress, allowing sorghum to be grown with fewer inputs and on marginal land. Variation in total biomass accumulation and grain yield between sorghum accessions, as well as between nitrogen conditions, can be largely explained by differences in vegetative …

Viewer Interactions In Animation, Megan Smith

Master of Fine Arts in Digital Media Culminating Experience

The art of animation can be viewed in a multitude of ways. Passive viewing, in which an audience is merely observing the acting and are unable to alter the animation in any way, such as watching a TV show or movie. Interactive camera viewings, such as Augmented Reality and Virtual Reality, in which the viewer can manipulate the content visually in the same way you observe the world, by moving the camera around in a digital space. Interaction-dependent viewing describes animations such as video games, where the player has full control of the character’s actions and the timing of those …

The Campaign Finance And Political Geography Of The 2020 Presidential Election Cycle, Chandler White

Political Science Undergraduate Honors Theses

This undergraduate honors thesis focuses on the 2020 Presidential Election between current President Joseph Biden and former President Donald Trump, and how the two candidates raised their money, geographically speaking, during the general election cycle. Presidential campaigns are more expensive than ever, and candidates now face the need to maintain levels of campaign spending that are comparable to their competing candidates. In order to maintain high levels of spending, these campaigns must raise funds effectively, and develop means in which they can outraise and outspend their competitors. In the financial funding race between campaigns, trends arise across election cycles regarding …

We Are Gullah: A Community Approach To Preserving Gullah Geechee Historical Sites Of Significance, Peter Gaytan

All Theses

The National Register of Historic Places is an inventory established by the National Historic Preservation Act of 1966 that identifies architectural and archaeological sites significant to American history. The National Register was created to encourage the documentation, evaluation, and protection of America’s historic resources. Over 96,000 historic properties, sites, and structures are currently listed on the National Register. Despite the number of historic places listed on the National Register there is still an overwhelmingly low number of sites listed on the National Register relating to underrepresented communities. This thesis assessed the definition of significance laid out in the National Register …

Nightmares And Hand Grenades: Dreams As A Storytelling Tool, Olivia Felber

All Theses

Dreams and nightmares feature prominently in art, story, and religious practice and tradition throughout history. In this paper I will discuss their prominence throughout these facets in daily life, and the various ways that we, as humans, have tried to elucidate meaning from them. I will study the nature and definition of dreams and nightmares through a scientific, cultural, and historical approach. I will also discuss folklore and the interpretation of nightmarish imagery in the context of an otherworldly adventure through a nightmare. These topics and themes will be shown, explained, and discussed through the methodology of my project- a …

Net-Zero Target And Emissions From Land Conversions: A Case Study Of Maryland's Climate Solutions Now Act, Philip Hutton

All Theses

Many climate change “solution” plans include net-zero goals, which involve balancing the anthropogenic greenhouse gas emissions (GHG) with their removal. Achieving net-zero goals is particularly problematic for soils because they are often excluded from GHG inventories and reduction plans. For example, Maryland’s Climate Solutions Now Act (Senate Bill 528) put forward a target of net-zero emissions by 2045. To achieve these goals, the state of Maryland (MD) needs to quantify GHG emissions. Soils are currently excluded from MD’s GHG assessments. This study examines the challenges in meeting net-zero goals by using carbon dioxide (CO₂). The current study quantified …

Investigating Consistency Of Landscape-Scale Green Infrastructure In Local Government Policy, Anna Wilson

All Theses

Planning for Climate Change is multifaceted and requires effort across all scales. Green Infrastructure networks of green spaces, natural lands, reserves, working lands, core habitat, riparian corridors, parks, open spaces, private conservations lands, and other complementary land uses work together to support life on earth and human existence through the ecosystem services provided. Clean air, clean water, carbon sequestration, food production, recreation, pollination, and spiritual and cultural benefits are only a few of the services that natural lands provide society. With climate change occurring due to human actions such as land use, development, and energy use, to name a few, …

Examining Pedestrian Accessibility To Opportunities In Four New Deal Villages, Maral Shemirani

All Theses

This study focuses on accessibility as an essential performance factor in city planning and urban development. The automobile-oriented designs that characterize and organize most modern United States cities, since the 1950s, have degraded pedestrian mobility and accessibility, causing people to be largely dependent on cars rather than walk, bike, and/or use public transit to reach essential and complementary daily destinations. This pervasive condition not only hinders community and sense of place, but also negatively affects people’s health and environment. We as planners should not forget that cities should be designed to serve people rather than cars. The more our …

Management Of Nematodes Associated With Tobacco And Sweet Potato Using Non-Fumigant Approach, Md Shah Alam

All Theses

Tobacco and sweet potato are attacked by several species of plant-parasitic nematodes leading to substantial yield losses. Because host-plant resistance is lacking in commercial cultivars and other common methods of nematode management either have low efficacy or pose adverse effects to the environment, controlled environment studies were conducted to evaluate the efficacy of non-fumigant chemical and biological nematicides against Meloidogyne enterolobii on tobacco and Rotylenchulus reniformis on sweet potato. Results suggest that fluensulfone was the most effective in suppressing M. enterolobii in tobacco, followed by oxamyl and fluopyram. The biological Burkholderia derived biological nematicide did not suppress the nematode population. …

Procedural City Generation With Combined Architectures For Real-Time Visualization, Griffin Poyck

All Theses

The work and research of this paper sought to build upon traditional city generation and simulation in creating a tool that both realistically simulates cities and their prominent features and also creates aesthetic and artistically rich cities using assets that combine several contemporary or near contemporary architectural styles. The major city features simulated are the surrounding terrain, road networks, individual buildings, and building placement. The tools used to both create and integrate these features were created in Houdini with Unreal Engine 5 as the intended final destination. This research was influenced by the city, town, and road networking of Ghost …

A Systematic Review Of Research On Treatment & Prevention Of The Neglected Tropical Disease Leishmaniasis, Aryn Akerberg

All Theses

Leishmaniasis is a life-threatening neglected tropical disease that is caused by the protozoa parasite, Leishmania. Over one million new human leishmaniasis cases occur each all over the world, affecting most the deeply impoverished regions of the world. The disease presents in three different forms: cutaneous leishmaniasis, mucocutaneous (mucosal) leishmaniasis, and visceral leishmaniasis. Symptoms can range from self-limiting lesion to more life-threatening conditions such as fever, kidney disease, and anemia. The Leishmania parasite is transmitted via the bite of the female phlebotomine sandfly and can infect many other mammals such as canines, rodents, bats, etc. The canine leishmaniasis epidemic is also …

An Investigation Of Community-Defined Boundaries And Important Sites, Emma Grace Sprinkle

All Theses

This thesis research investigates and documents how individuals within the African American settlement communities of Cross Cut, Ferguson Village/Down Cut, and Sol Legare define the boundaries and important sites of their community. The purpose of the study is to better understand how individuals define their community’s boundaries, rather than historic preservation and planning professionals defining them. It seeks to determine the importance of factors such as houses, churches, schools, streets, farm lands, cemeteries, and community gathering spaces to boundary drawings as well as the influence of current address, age, and time spent in the community on participants’ boundaries. Before this …

Unidentified Deceased Persons: Who Are At-Risk?, Sarah Duncan

All Theses

This study explores the silent mass disaster of unidentified deceased persons that is occurring across the United States and identifies the individual and community level characteristics that make a person “at-risk” of becoming an unidentified deceased person within the United States. This study identifies trends-based hotspots by using data reported on the National Missing and Unidentified Persons System (NamUs) and comparing those trends to the gender United States population. It finds that males, and age of death between 20-64 are overrepresented and White persons are underrepresented in the unidentified deceased person sample when compared the general population. Social and human …

An Emergentist Critique Of The Contract Theory Of The State Of Nature, With A Consideration On Two Types Of Polity And Their Origins., Ryan A. Apperson

College of Arts & Sciences Senior Theses

The theories of the state of nature provided by the political philosophers Thomas Hobbes and John Locke have made a significant impact in the general conceptions of the origin of states. Though there are many critical differences in the conceptions of the state of nature between each in their seminal works, they both possess of a view of states that is rational and constructivist.

In this paper, I use the game theory concepts of the coordination game, collective action problem, and focal point to illustrate a lacuna in this rational and constructivist conception of the origin of states, as their …

Transferred Emissions Are Still Emissions: Why Fossil Fuel Asset Sales Need Enhanced Transparency And Carbon Accounting, Jack Arnold, Martin Lockman, Perrine Toledano, Martin Dietrich Brauch, Shraman Sen, Michael Burger

Columbia Center on Sustainable Investment

In a widely reported trend, the “Oil Supermajors” — BP, Chevron, ConocoPhillips, Eni, ExxonMobil, Shell, and TotalEnergies — are selling off many upstream fossil fuel assets.

Selling these assets to entities that will continue producing and selling the fossil fuel resources does not necessarily reduce greenhouse gas emissions, but the supermajors have used these asset sales to support claims that they are making progress toward reaching net-zero greenhouse gas emissions.

Emissions reporting frameworks allow companies to conflate the apparent emissions reductions from asset sales with direct reductions from efficiency improvements and asset retirements. In doing so, they hinder the ability …

Green Infrastructure In The Ozarks: Northwest Arkansas Development Policy And The Open Space Plan, Daniel Holtmeyer

Graduate Theses and Dissertations

Northwest Arkansas regional planning authorities in 2016 released the Northwest Arkansas Open Space Plan, a voluntary document outlining ways to protect and preserve important open spaces even as the region’s population balloons and urban development spreads outward. No one appears to have made a systematic attempt to gauge the Plan’s impact on development decisions, however. In this thesis, I conduct a qualitative survey of several cities and counties’ planning codes and comprehensive plans to determine how much these policies have in common with the Open Space Plan’s essential principles. From that survey, I also conduct two case studies of recent …

Reproducibility And Replicability In Unmanned Aircraft Systems And Geographic Information Science, Cassandra Howe

Graduate Theses and Dissertations

Multiple scientific disciplines face a so-called crisis of reproducibility and replicability (R&R) in which the validity of methodologies is questioned due to an inability to confirm experimental results. Trust in information technology (IT)-intensive workflows within geographic information science (GIScience), remote sensing, and photogrammetry depends on solutions to R&R challenges affecting multiple computationally driven disciplines. To date, there have only been very limited efforts to overcome R&R-related issues in remote sensing workflows in general, let alone those tied to disruptive technologies such as unmanned aircraft systems (UAS) and machine learning (ML). To accelerate an understanding of this crisis, a review was …

The human gut microbiome is a burgeoning field of research due to recent recognition of its profound impact on the human hosts’ homeostasis, physiology and metabolism, and disease. Botanical natural products have been utilized for disease prevention and medical treatment since ancient times. Increased consumption of botanical natural products for their health benefits have led researchers to investigate interactions between the gut microbiome and botanical natural products. Garcinia mangostana, also known as mangosteen, is a fruit from Southeast Asia that is known for its health benefits such as anti-inflammatory, antihypertensive, and anticancer properties. Its benefits have been linked to bioactive …

Living And Dying In 'Cancer Alley': Using Human Rights Law And Environmental Justice To Create A Litigation Framework For Marginalized Communities, Neeharika Sistu

Honors Scholar Theses

Cancer Alley, Louisiana is a poignant example of the intersection between environmental justice, legal harm, and human rights abuses. This thesis dissects the laws and policies underpinning the creation of Cancer Alley with special attention to how they constitute human rights abuses under the International Covenant on Civil and Political Rights and the International Convention on the Elimination of All Forms of Racial Discrimination.

Then, by performing a comprehensive analysis of litigation surrounding environmental justice in Louisiana, this thesis scrutinizes the efficacy of environmental law in creating environmental justice and suggests the integration of international human rights law and environmental …

Meta-Method Analysis On Therapists’ Experiences: An Inquiry Into Qualitative Psychotherapy Research Methodology, Javier L. Rizo

Graduate Masters Theses

I conducted a meta-method study to explore the methodological and reporting characteristics of qualitative studies on therapists’ experiences conducting psychotherapy. Articles were identified through a PsycINFO search, and through a review of article text their methodological and reporting features were coded and quantitatively analyzed. Consideration was given to standards of qualitative research in psychology, especially methodological integrity. Results showed increases in the number of these qualitative studies from the 2000s onwards. This rise seems to be above that in psychology, but comparable to other psychotherapy literature. Publication characteristics of this body of literature, namely journal discipline and impact score, showed …

Spirits And Spirituality: Temperance And Racial Uplift In Nineteenth-Century Nantucket, Ma, John T. Crawmer

Graduate Masters Theses

Studies of alcohol consumption have shown alcohol’s role in defining social boundaries based on class and ethnicity, but few have interrogated alcohol in the context of race. During the early-19th century, free black communities were encouraged to refrain from alcohol as part of a larger project of racial uplift. Black societies and churches perceived intemperance as not only immoral but a threat to community survival. Excavations of the Nantucket African Meeting House noted a considerable lack of alcohol bottles, but it was unclear whether temperance was equally observed at the neighboring Boston-Higginbotham House. This research uses a minimum number of …

New Intimacies, Louis Chavez

Theses

“New Intimacies” is a photographic study situated in environments known for gay cruising and public sex. Taking influence from Peter Hujar and the photographs he created in the cruising areas around Manhattan’s meatpacking district, I made experimental images that sought to envision the intangible and fleeting qualities of these geographic spaces. The inclusion of various photographic strategies (such as landscapes, portraits, and abstraction) implores the audience to consider the social and cultural elements that contributed to the formation of these sites as spaces of community and public intimacy. The work is also influenced by queer zines, experimental cinema, and other …
