Enhancing Cross-Cultural Communication In Low-Resource Language Conversational Agents, Hardi V. Trivedi

Master's Theses

Recent advancements in natural language processing (NLP) and large language models (LLMs) have facilitated the development of systems capable of generating human-like responses across a wide range of tasks. However, the majority of research has focused predominantly on English, overlooking the vast linguistic diversity globally. For true global inclusivity, extending research to other languages is crucial, particularly as it can significantly benefit various sectors such as business, healthcare, government, and education. A major challenge in this expansion is the scarcity of digital data available and the limited number of pre-trained models for low-resource languages. Our research specifically addresses these challenges …

Swim Bladder Morphology Influences The Responses Of Nearshore Rockfishes To Barotrauma, Molly K. Alvino

Master's Theses

Rockfishes (Sebastes spp.) are ecologically and economically important fishes in the continental shelf and slope regions of the Eastern Pacific Ocean. All species within the Sebastes genus have a buoyancy organ, the swim bladder, which is sensitive to rapid changes in pressure that occur when fish are caught and brought up to the surface. Although all rockfishes have swim bladders, pressure-related injuries (barotrauma) affect rockfish species differently. I determined whether swim bladder morphology can explain differences in barotrauma among semi-pelagic (Blue and Olive rockfish) and benthic (Gopher and Vermilion rockfish) species that occupy different habitat zones. Seven different swim bladder …

Sadomasochistic Sensations: A Phenomenological Analysis Of Black Ontology, Embodiment, And Transcendence, Sam Forrey

Master's Theses

Over the past fifteen years, feminists have challenged the notion that sexual sadomasochism perpetuates racial and gender-based violence, and instead claim that the practice can be a powerful site to control and subvert oppression. In this thesis, I contribute to this growing discourse and argue that sensations experienced during practices of Black sexual sadomasochism and attention to the feelings and affects that arise from them can be used to mediate Black being in a violently antiblack United States. Through applications of Black feminist thought, Black anti-humanism, and phenomenology, I claim that antiblack oppression denies Black people the experience of tactile …

A Matter Of Life And Death: The Conceptualization And Theological Significance Of Blood In The Pentateuch, Jared Greer

Master's Theses

This 2024 Master of Theological Studies thesis at Lipscomb University analyzes the conceptualization and theological significance of blood within the Pentateuch. While the thesis does attend to various anthropological concerns (i.e., the sociocultural understandings of blood that inform the text), it is more chiefly concerned with how such understandings of blood contribute to the broader theology of the Pentateuch. Using a canonical interpretive approach that respects both the diachronic nature of the text and the theological unity intended by its final redactors, the thesis primarily explores the two principal contexts in which blood appears in the Pentateuch: Israel’s cultus and …

A Qualitative Evaluation Of Speech Sound Disorder Treatment Apps For Children, Rachel G. Barnett

Master's Theses

This research examined 20 speech sound disorder (SSD) treatment apps’ features and costs as related to the feature matching process within speech-language therapy.

Results indicated that app cost was not a good predictor of feature quantity and contemporary apps had some relevant feature …

Language Dominance And Connected Speech In Multilingual Spanish-English Adults, Alyson Jimenez

Master's Theses

With a growing prevalence of multilingual, Spanish-English speakers in the United States, speech-language pathologists (SLPs) face limited research to learn about how to evaluate the language skills of this population. Exploring evaluation tools, more specifically, connected speech samples, and their effectiveness in assessing the dynamic nature of multilingualism with adults who speak Spanish and English can assist SLPs in making informed recommendations. This study aimed to investigate relations between language dominance and connected speech with cognitive-healthy multilingual Spanish-English adults. Language dominance was further examined by two perspectives that an SLP may utilize in their evaluation: evaluated and perceived. Correlations between …

Confronting The Myths Of “Classical” Keyboard Improvisation: A Historical Evaluation, Examination, And Re-Incorporation Of Improvisation In Contemporary Piano Education And Performance, Kiefer Taylor

Master's Theses

Improvisation has been a highly valued skill in all periods of Western keyboard music. Many composers were also famous as keyboard improvisers and demonstrate the importance of improvisation as a tradition in “classical” keyboard performance. Strangely, today’s pianists, who perform the canonical eighteenth- and nineteenth-century works of these composers, no longer practice or incorporate improvisation into performance and instead play “only from the score.” Improvisation has also disappeared from the modern education of “classical” piano performers. Since improvisation was central to the performance practice of past keyboard repertoire, why does modern piano education not teach improvisation as a standard part …

An Exploration Of Dimensionality Reduction Of Dynamics On Lie Groups Via Structure-Aware Canonical Correlation Analysis, Wooyoung Chung

Master's Theses

Incorporating prior knowledge into a data-driven modeling problem can drastically improve performance, reliability, and generalization outside of the training sample. The stronger the structural properties, the more effective these improvements become. Manifolds are a powerful nonlinear generalization of Euclidean space for modeling finite dimensions. When additionally assuming that the manifold carries (Lie) group structure, this imposes a drastically stricter global constraint. The range of their applications is very wide and includes the important case of robotic tasks. We apply this idea to Canonical Correlation Analysis (CCA). In traditional CCA one constructs a hierarchical sequence of maximal correlations of up to …

“It Makes Me Wonder, How I Keep From Goin’ Under:” Deconstructing Cultural Strengths In The Stories Of Black College And University Students, Sikeza C. Fowlks

To create a full conceptualization of Black issues and cultural resilience this study explored the current literature around Black experiences of racism and its relationship to Race-Based Trauma. Additionally, the researcher expanded upon current interventions used to mitigate Race-Based Trauma and how Black culture is currently defined within systemic oppression. To answer the study’s research question framework around Black cultural …

Domain Specific Aspect Extraction For Product Design, Divyam Sobti

Master's Theses

As technology advances, computers become increasingly proficient at interpreting and translating human language into machine-understandable text. With the help of algorithms in natural language processing (NLP), machines can now translate textual data. These algorithms help identify and extract specific text components known as aspects. The aspects represent specific attributes or topics within textual data. For instance, an Amazon review states,“ This phone has good battery life but poor camera quality,” and attributes like ‘battery life’ and ‘camera quality’ represent aspects in the text. Aspect extraction is a pivotal process involving identifying and isolating key features or topics within text. This …

Product Design For Repairability: Identifying Failure Modes With Topic Modeling And Designing For Electronic Waste Reuse, Claire J. Franz

Master's Theses

Design for repairability is imperative to making products that last long enough to justify the resources they consume and the pollution they generate. While design for repairability has been gaining steady momentum, especially with recent advances in Right to Repair legislation, there is still work to be done. There are gaps in both the tools available for repair-conscious designers and the products coming onto store shelves. This thesis work aims to help set sails in the right direction on both fronts.

This research explores the use of topic modeling (a natural language processing technique) to extract repairability design insights from …

What Gives? Trust, Risk, Altruism, And Reciprocity Across 76 Countries, Sherwin Mosavat

Master's Theses

Abstract:

The decades-long literature pertaining to gender-specific preferences lies at the intersection of economics and psychology with a primary focus on the correlation between economic development and gender-specific preferences. Better understanding of this correlation has helped researchers understand how individuals make decisions for their education, finances, and occupation. Falk & Hermle (2018) assess the correlation between GDP and various gender-specific preferences including trust, risk, altruism, and reciprocity. In order to better understand the relationship between economic development and gender-specific preferences, I expand on the Falk & Hermle 2018 framework by introducing new macroeconomic, prosocial, and cultural variables as additional explanatory …

Lgbtqia+ Immigrant Healing: Ulysses Syndrome & Community-Based Organizing, Tay Villaseñor-Ingersoll

Master's Theses

The aim of this study is to validate that LGBTQIA+ migrants experience the Ulysses Syndrome, also referred to as the Immigrant Syndrome of Chronic and Multiple Stress, which was developed in 2002 by Psychiatrist and Professor of the University of Barcelona, Dr. Joseba Achotegui. This is an impermanent and complex grieving process which exposes one to symptoms such as depression, anxiety and dissociative somatic symptoms which result from extreme levels of stress from the processes of modern migration. This syndrome manifests as a natural reaction to intense migratory pressures for those who are otherwise healthy.

Furthermore, this project highlights how …

Queering The Care Chain & Migration Discourse, Duun O'Hara

Master's Theses

Abstract

This thesis seeks to fill the gaps between migration and domestic labor discourses that lack a queer, decolonial conception of the queer migrant community in the US. Dominant conceptualizations of care work exclude LGBTQ+ migrant individuals who are forced into the “informal” sector of labor as a by-product of the settler-colonial state, neoliberalism, and globalization. Centering queer migration approaches and decolonial practices will help to illuminate how gender, race, and sexuality are consistently excluded in discussions of migrant domestic workers. To investigate how migration discourse and understandings of care work continue to impose Western heteronormative perceptions of migrants, I …

Generalized Model To Enable Zero-Shot Imitation Learning For Versatile Robots, Yongshuai Wu

Master's Theses

The rapid advancement in Deep Learning (DL), especially in Reinforcement Learning (RL) and Imitation Learning (IL), has positioned it as a promising approach for a multitude of autonomous robotic systems. However, the current methodologies are predominantly constrained to singular setups, necessitating substantial data and extensive training periods. Moreover, these methods have exhibited suboptimal performance in tasks requiring long-horizontal maneuvers, such as Radio Frequency Identification (RFID) inventory, where a robot requires thousands of steps to complete.

In this thesis, we address the aforementioned challenges by presenting the Cross-modal Reasoning Model (CMRM), a novel zero-shot Imitation Learning policy, to tackle long-horizontal robotic …

Primate Social Behavior And Embodied Action, Maria Elbon

Master's Theses

The evolutionary origins of uniquely human cognitive processes remain poorly understood. Comparative analysis between humans and great apes can help identify derived characteristics and extrapolate ecological conditions leading to the evolution of specifically human cognitive abilities. It has been posited that the relatively large brain size of primates, in relation to body size, evolved in response to increasing social complexity and the accompanying cognitive demands placed on gregarious organisms that need to maintain cohesive, functional groups. Studies examining primate social behavior and cognition have focused on foundational abilities and cognitive capacities that are theorized to act as progenitors to uniquely …

Gangs And Tiktok: A Content Analysis Of Violence Exposures On Social Media, Paige Giddens

Master's Theses

Internet use among individuals involved with gang activity has become increasingly prevalent in the last two decades. This usage goes beyond simply organizing or boasting about criminal activity. Rather, it has become similar to general usage of the internet including posting content that contributes to an overall image of themselves or their gang. Moreover, as social media has become more common among the general population, those involved in gang activity have also followed suit. Previous studies have noted several themes communicated that are in social media posts made by self-proclaimed gang members. These themes include violent imagery, intimidation, revenge, grief, …

Does Appearance Matter? The Relationship Of Perceived Body Size And Physical Appearance On Students' Attraction To Physical Activity At Recess, Danielle Belcher

Master's Theses

Drastic declines in recess physical activity (PA) have been observed within recent years (Center for Disease Control (CDC), 2017). Due to recess’ discretionary nature, psychosocial variables associated with PA are predictors of students’ PA levels. Recess is also a time of heightened bullying occurrences (Vaillancourt et al., 2010). Appearance-based bullying is the most common type of victimization that occurs in schools, transpiring more often in children with larger body max indexes (BMI), and possibly altering students’ physical self-perceptions. Physical self-perceptions have been shown to impact PA motivation, however, it is still unknown the extent to which appearance-based bullying, body size, …

Sustainable Development: What’S The Problem Here? A Post-Structural Discourse Analysis Of The Global Reporting Initiative, Jenniffer Barnett

Master's Theses

The purpose of the study was to critically analyze how the problem of sustainable development is constructed in the Global Reporting Initiative (GRI) and identify what underlying assumptions and historical events produced the problematization as the GRI aims to guide global behavior. The study explored how governing took place by identifying what was silenced in the problem representation and the discursive effects and subject positions it produced. Carol Bacchi's (2009) "What’s the problem represented to be?" (WPR) facilitated this Foucault-influenced poststructural discourse analysis. The interrogation revealed that (a) sustainable development is characterized as a problem of corporate transparency, and (b) …
