A detailed uplift history of the Tibetan Plateau is essential for disentangling the proposed geodynamical models and assessing its impacts on climate and biodiversity. However, when and how the plateau formed remains highly controversial. Here, we present unusual geochemical indicators of marine signatures in the Cenozoic terrestrial strata of the Qaidam Basin, northern Tibetan Plateau, with strong implications for the basin altitude. Our investigations across the basin reveal typical marine alkenones and anomalously high carbonate carbon isotopic values during the mid-Miocene, but not at earlier stages, which are accompanied by a divergent trend in the paired carbonate oxygen and leaf …

African Bovid Tribe Classification Using Transfer Learning And Computer Vision, Manuel Domínguez-Rodrigo, Juliet Brophy, Gregory J. Mathews, Marcos Pizarro-Monzo, Enrique Baquedano

Faculty Publications

Objective analytical identification methods are still a minority in the praxis of paleobiological sciences. Subjective interpretation of fossils and their modifications remains a nonreplicable expert endeavor. Identification of African bovids is a crucial element in the reconstruction of paleo-landscapes, ungulate paleoecology, and, eventually, hominin adaptation and ecosystemic reconstruction. Recent analytical efforts drawing on Fourier functional analysis and discrimination methods applied to occlusal surfaces of teeth have provided a highly accurate framework to correctly classify African bovid tribes and taxa. Artificial intelligence tools, like computer vision, have also shown their potential to be objectively more accurate in the identification of taphonomic …

Relationship Between Arm Path, Ball Velocity, And Elbow Varus Torque In Professional Baseball Pitchers, Brittany Dowling, Alexander Hodakowski, Bjorn Olmanson, Matthew Cohn, Patrick Pauley, Nikhil Verma, Gregory Nicholson, Grant Garrigues

Rothman Institute Papers

BACKGROUND: Currently, most pitching instructors suggest a shorter arm path-the total distance the arm travels during pitching. Theoretically, this combination allows for better body segment sequencing, a more efficient energy transfer through the kinetic chain, and increased ball velocity, while limiting elbow varus torque.

HYPOTHESIS: Shorter arm paths would be associated with increased ball velocity and decreased elbow varus torque.

STUDY DESIGN: Descriptive laboratory study.

METHODS: A total of 182 professional pitchers threw 8 to 12 fastball pitches while evaluated by 3-dimensional motion capture (480 Hz). The arm path was calculated as the total distance the hand marker traveled during …

Portraits Of Happiness (The Performance Of Happiness: A Cultural Critique), Meaghan Hibbs

Honors Theses

While happiness may be something seemingly everyone, or most, people wish for, what happiness consists of, how to obtain it, and how to determine if/when one is truly happy remains elusive. One may view happiness as a simple wish, but then arises the question: what exactly does one wish for in wishing for happiness? Or, moreover, what may a society wish for or wish to ensure through the imperative to be happy? My thesis will primarily involve an interpretation of philosopher Sara Ahmed’s book The Promise of Happiness, in which she offers a critique of “happiness,” or, moreover, the cultural …

Tales Of The Keyworld: An Examination Of The Study And Application Of Craft Theory For Writers, Lauren Bruce

Honors Theses

The following consists of a craft essay focused on character and close third-person narration and a novel excerpt. The craft essay begins with a discussion of what craft theory is and how it is useful to writers when used together with reading analysis. It then synthesizes the conversation around close third-person narration and character and applies it to a close reading analysis of Throne of Glass by Sarah J. Maas. The novel excerpt comes from the middle of a work in progress and concerns members of the Keyworld, a fantastical sub-layer of the modern world unknown to most humans.

Monocular Depth Estimation For Glass Walls With Context: A New Dataset And Method, Yuan Liang, Bailin Deng, Wenxi Liu, Jing Qin, Shengfeng He

Research Collection School Of Computing and Information Systems

Traditional monocular depth estimation assumes that all objects are reliably visible in the RGB color domain. However, this is not always the case as more and more buildings are decorated with transparent glass walls. This problem has not been explored due to the difficulties in annotating the depth levels of glass walls, as commercial depth sensors cannot provide correct feedbacks on transparent objects. Furthermore, estimating depths from transparent glass walls requires the aids of surrounding context, which has not been considered in prior works. To cope with this problem, we introduce the first Glass Walls Depth Dataset (GW-Depth dataset). We …

Research Collection School Of Computing and Information Systems

The proliferation of online video content underscores the critical need for effective sentiment analysis, particularly in safeguarding children from potentially harmful material. This research addresses this concern by presenting a multimodal analysis method for assessing video sentiment, categorizing it as either positive (child-friendly) or negative (potentially harmful). This method leverages three key components: text analysis, facial expression analysis, and audio analysis, including music mood analysis, resulting in a comprehensive sentiment assessment. Our evaluation results validate the effectiveness of this approach, making significant contributions to the field of video sentiment analysis and bolstering child safety measures. This research serves as a …

The Conferred Jurisdiction Of The International Criminal Court, Leila Nadya Sadat

Notre Dame Law Review

After twenty years of operation, we know that the International Criminal Court (ICC) works in practice. But does it work in theory? A debate rages regarding the proper conceptualization of the Court’s jurisdiction. Some have argued that the ICC’s jurisdiction is little more than a delegation by states of a subset of their own criminal jurisdiction. They contend that when states ratify the Rome Statute, they transfer some of their own prescriptive or adjudicative criminal jurisdiction to the Court, meaning that the Court cannot do more than the state itself could have done. Moreover, they argue that these constraints are …

Co2 Storage Capacity And Injectivity Of Stacked Carbonates Of The Pennsylvanian And Permian In Western Nebraska, Lateef Lawal

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Geological carbon storage (GCS) is a critical aspect of carbon capture and storage (CCS) in which captured CO₂ from power plants and industrial processes is injected and stored securely underground. Potential subsurface rock formations include saline aquifers, depleted oil and gas reservoirs, unmineable coal seams and volcanic rocks. GCS technology has been proven in the United States and many other parts of the world as a net-zero carbon emission strategy to mitigate the current climate crisis of our planet. Unlike other states such as Wyoming, GCS projects are still in the early phases in Nebraska. The goal of this …

Bridge Deck Overhang Design: Effective Vehicle Impact Loads, Ultimate Strength, And Implications On Bridge Rail Performance, Andrew Eric Loken

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

When an errant vehicle strikes a bridge railing on a typical girder bridge, impact loads are transmitted downward through the railing and inward through the deck overhang to the primary superstructure elements. In this research effort, design demands for deck overhangs supporting concrete railings were characterized using physical testing and complementary modeling in LS-DYNA. Physical test and modeling results were also used to better characterize the ultimate strength of overhangs supporting post-and-beam railings. Ultimately, a novel design methodology for deck overhangs was developed and proposed for adoption to the AASHTO LRFD Bridge Design Specifications (BDS).

For overhangs with solid concrete …

An Icfd Fluid Model Used In A Mash Tl-6 Vehicle Model, Md Zunayed Habib

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

The objective of this thesis was to develop an ICFD finite element model of a partially filled deformable container suitable for impact scenarios. This model will be later incorporated into the existing TL-6 vehicle model, which is a tractor-tank trailer vehicle model. Previous finite element fluid models for the TL-6 vehicle used an elastic fluid model, which could not predict the fluid behavior correctly.

A study was conducted on the ICFD modeling and an improved ICFD model has been developed using the LS-DYNA, a finite element analysis software. Different properties and parameters of the fluid and the container were adopted …

Characterization Of Interlayer Laser Shock Peening During Fused Filament Fabrication Of Polylactic Acid (Pla), Fabien Denise

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

The field of additive manufacturing (AM) has gained a significant amount of popularity due to the increasing need for more sustainable manufacturing techniques and the adaptive development of complex product geometries. The problem is that AM parts routinely exhibit flaws or weaknesses that affect functionality or performance. Over the years, surface treatments have been developed to compensate certain flaws or weaknesses in manufactured products. Combining surface treatments with the modularity of additive manufacturing could lead to more adaptable and creative improvements of product functions in the future. The current work evaluates the feasibility of pursuing a new research axis in …

Anthropogenic Effects On Global Soil Nitrogen Pools, Shih Chieh Chien, Jennifer Adams Krumins

Department of Biology Faculty Scholarship and Creative Works

The amount of nitrogen stored in terrestrial soils, its “nitrogen pool”, moderates biogeochemical cycling affecting primary productivity, nitrogen pollution and even carbon budgets. The soil nitrogen pools and the transformation of nitrogen forms within them are heavily influenced by environmental factors including anthropogenic activities. However, our understanding of the global distribution of soil nitrogen with respect to anthropogenic activity and human land use remains unclear. We constructed a meta-analysis from a global sampling, in which we compare soil total nitrogen pools and the driving mechanisms affecting each pool across three major classifications of human land use: natural, agricultural, and urban. …

Vozick Hans, Alexandra, Sophia Maier Garcia

Bronx Jewish History Project

Alexandra Vozick Hans was born to Canadian parents, who, upon moving to New York, lived in the Amalgamated Housing Cooperative, where she grew up. She remained in the Bronx until she graduated college in 1966. After college, she moved to Boston and became a social worker.

Hans and her family were socialists, and Hans recalls tensions between the socialists and the communists in the Amalgamated. She also recalls tensions over the issue of integration in the building: the Amalgamated was not integrated, and residents complained about the lack of integration. Overall, however, Hans looks back with great fondness on the …

Covariance-Based Causal Debiasing For Entity And Relation Extraction, Lin Ren, Yongbin Liu, Yixin Cao, Chunping Ouyang

Research Collection School Of Computing and Information Systems

Joint entity and relation extraction tasks aim to recognize named entities and extract relations simultaneously. Suffering from a variety of data biases, such as data selection bias, and distribution bias (out of distribution, long-tail distribution), serious concerns can be witnessed to threaten the model’s transferability, robustness, and generalization. In this work, we address the above problems from a causality perspective. We propose a novel causal framework called covariance and variance optimization framework (OVO) to optimize feature representations and conduct general debiasing. In particular, the proposed covariance optimizing (COP) minimizes characterizing features’ covariance for alleviating the selection and distribution bias and …

Wsdms: Debunk Fake News Via Weakly Supervised Detection Of Misinforming Sentences With Contextualized Social Wisdom, Ruichao Yang, Wei Gao, Jing Ma, Hongzhan Lin, Zhiwei Yang

Research Collection School Of Computing and Information Systems

In recent years, we witness the explosion of false and unconfirmed information (i.e., rumors) that went viral on social media and shocked the public. Rumors can trigger versatile, mostly controversial stance expressions among social media users. Rumor verification and stance detection are different yet relevant tasks. Fake news debunking primarily focuses on determining the truthfulness of news articles, which oversimplifies the issue as fake news often combines elements of both truth and falsehood. Thus, it becomes crucial to identify specific instances of misinformation within the articles. In this research, we investigate a novel task in the field of fake news …

Interpreting Codebert For Semantic Code Clone Detection, Shamsa Abid, Xuemeng Cai, Lingxiao Jiang

Research Collection School Of Computing and Information Systems

Accurate detection of semantic code clones has many applications in software engineering but is challenging because of lexical, syntactic, or structural dissimilarities in code. CodeBERT, a popular deep neural network based pre-trained code model, can detect code clones with a high accuracy. However, its performance on unseen data is reported to be lower. A challenge is to interpret CodeBERT's clone detection behavior and isolate the causes of mispredictions. In this paper, we evaluate CodeBERT and interpret its clone detection behavior on the SemanticCloneBench dataset focusing on Java and Python clone pairs. We introduce the use of a black-box model interpretation …

A Case Study Of The Political Determinant Of Health On The Public Health Crisis Of Malaria In Nigeria, Bisola M. Olumegbon

Electronic Theses and Dissertations

Abstract

Globally, there were about 229 million cases of malaria in 2022. The sub-Saharan African region accounted for 92% of the reported cases and 94% of deaths. Nigeria had the highest number of malaria cases and deaths, representing 27% of global cases. This scholarly project was a case study guided by the political determinants of health. Triangulation of data using thematic analysis was used to identify the political determinants of malaria in Nigeria and to understand how the concept of interaction contributes to the persistence of the disease. The analysis involved a deductive and inductive approach based on the literature …

Intergenerational Factors That Contribute To Millennial Church Engagement, Parker Sanderson

Electronic Theses and Dissertations

Millennial church attendance has declined since the beginning of the new millennium. Intergenerational ambivalence has been known to contribute to this phenomenon. Through this action research, the researcher sought to determine what intergenerational factors have led to millennials’ continued or discontinued attendance within churches. A phenomenological qualitative approach centered around interviews for this study was used to determine these intergenerational factors. The sample was taken from a 1,100-member church in a major Texas metropolitan area. The goal was to help church leaders decrease relational distancing and reduce ambivalent factors to increase millennial engagement in this local congregation.

What Discrimination? Christian Microaggression Rhetoric Against Nontheists, Nicole Dolfi Hall

Electronic Theses and Dissertations

Theories of microaggressions have been used in the last decade as a framework for studying subtle forms of discrimination against racial minorities and other marginalized groups. However, there is a dearth of research on the scope and types of microaggressions nontheists face. This qualitative study examines microaggressions against nontheists by interviewing 16 religious Christians on their experiences and opinions of the discrimination Christians and nontheists face. The narratives were analyzed for thematic patterns between the rhetoric used and the type of microaggressions employed. The study revealed nine categories of microaggressions. The findings also showed how experiences of discrimination, political viewpoint, …

Isotopic Ecology Of Bison And Bootherium At Big Bone Lick, Kentucky, Frances Stephenson

Electronic Theses and Dissertations

Big Bone Lick (BBL) is a late Pleistocene and Holocene fossil locality in the Ohio River valley of Kentucky. This study utilized stable isotopes (δ¹³C, δ¹⁸O, and ⁸⁷Sr/⁸⁶Sr) in tooth enamel to reconstruct mobility and diet in Bison, as well as diet in Bootherium bombifrons. Isotopic results from seven Bison and two B. bombifrons are reported. Results suggest Pleistocene Bison and Bootherium occupied different dietary niches. Although both had C3-dominated diets, Bison occupied more open environments than B. bombifrons. Two bison from the late Holocene deposit had diets that consisted …

Music With A Racial Nexus: Culture Clash In Los Angeles Punk Rock Communities, 1976-1981, Lawson Hammock

Electronic Theses and Dissertations

The chief argument of this work rests on the idea that culture-blindness—especially White ethnic-cultural blindness—contributed as much as issues of race to the heavily documented social rift between predominantly Chicanx, Eastside punk and the mostly-White, Westside punk rock communities of Los Angeles, 1976-1981. To date, historical blame for the divide has centered on racism, including racist intent. The second area of analysis directly relates to the first in that it demonstrates the inextricable link between cultural and spatial identity formation and assignment among the various scenes. This aspect of the study evaluates the complaints of some Eastside acts who have …

Papa Was A Missing Stone: An Exploration Into The Lived Experiences Of Father-Absent African American Women, Jamila Jordan Moody

Electronic Theses and Dissertations

This qualitative phenomenological study examines the lived experiences of adult father-absent African American women to extrapolate from their stories the meaning they attached to the experience and to hear in their own words how they perceived the absence of their father shaped their lives and affected them socially, emotionally, behaviorally, and educationally. Twelve semi-structured interviews were conducted via Zoom audio-conferencing with adult African American women who ranged in age from 20-62 years of age living in various parts of the U.S. The findings of this study revealed that father-daughter relationship bonds held a special meaning to each participant as most …

Covid-19 Vaccine Uptake In The Hispanic And Latinx Communities Of Northeast Tennessee, Gabriela Abrego

Electronic Theses and Dissertations

This work addresses the underlying issues surrounding COVID-19 vaccine uptake in Hispanic and Latinx communities in the Northeast region of Tennessee. A qualitative, phenomenological research approach was used to conduct interviews and data from the interviews was used to inform a survey instrument. The interview guide in the qualitative phase of the study was based on the Health Belief Model (HBM) developed by Rosenstock (Rosenstock, 1974). A quantitative approach was then used by piloting the survey instrument in the study population. Common themes found through the interviews were: previous negative experience with COVID-19 vaccination, previous negative experience as a result …

Educators’ Perceptions Of Trauma-Informed Instructional Practices In One Northeast Tennessee School District, Alecia Burleson

Electronic Theses and Dissertations

The purpose of this qualitative phenomenological study was to investigate the perceptions of classroom-level educators regarding the application of trauma-informed instructional practices. This was achieved by evaluating educators' understanding of the influence of trauma on students, their level of familiarity with trauma-informed instructional practices, and their assessments of the effectiveness of these practices. Trauma refers to an individual's response to a single traumatic incident, a succession of traumatic events, or extended exposure to a traumatic event (SAMHSA, 2014). As awareness of the prevalence of childhood trauma has increased, it is acknowledged as a serious public health issue (Lang et al., …

Crossing The Pond: The Influence Of Southern Appalachian Old-Time On Contemporary Irish Music, Amanda Morgan

Electronic Theses and Dissertations

Numerous studies examine Irish traditional music influencing old-time music, but few examine the influence of old-time on contemporary Irish. As our societies become more global, folk music travels faster and becomes more open to influence. Thes influences can be heard in the music of “Alfi” and “Lankum,” two ensembles steeped in Irish traditional music.

This study defines common musical elements of old-time and examines the use of those elements in two recordings: Alfi’s, “Jubilee” and Lankum’s, “The Old Man from Over the Sea.” Much of my data comes from interviews with Irish and American musicians and my own professional knowledge, …
