A cross-sectional online survey was administered to 175 caregivers of children actively receiving feeding therapy only (n = 34), speech-language therapy only (n = 93), or combined feeding and speech-language therapy (n = 48). Food insecurity was assessed using the USDA Household Food Security Survey Module: Six-Item Short Form, and parent engagement was …

A Multimodal Critical Discourse Analysis Of Texas History Curriculum Discourse, Maribel Santoyo

Open Access Theses & Dissertations

This qualitative study examines how race, citizenship, nation-building, and belonging are constructed across Texas history curriculum discourse. Grounded in Fairclough's three-dimensional model of discourse, Machin and Mayr's (2012) multimodal framework, Weedon's (1987) theory of subjectivity, Foucault's (1980) concept of power/knowledge, and Anderson's (1983) concept of imagined communities, the study investigates how official curriculum texts shape the histories students are invited to know and the civic identities they are invited to inhabit. Findings suggest that the Texas history TEKS, SB3, and Texas history textbooks for Grades 4 and 7 work together as an interconnected discourse system through which official knowledge is …

"Fenomeno Frontera:" Family Language Policy As Lived Experience At The U.S.-Mexico Borderlands, Alejandra Sanmiguel-Lopez

Open Access Theses & Dissertations

Family language policy (FLP) research expands the understanding of how families' language ideologies, language management, and language practices shape children's bilingual development. However, limited research has examined these processes among transfronterizo families living along the U.S.-México border. This qualitative narrative inquiry explores how transfronterizo families describe and negotiate their family language policies and how these policies relate to their experiences in the borderland, including their relationships with schools. Guided by family language policy and borderlands theory, this dissertation employs Seidman's (2006) three-interview series with five transfronterizo mothers raising children enrolled in dual language programs in the El Paso, Texas, region. …

Essays On Firm-Level Political Risk, Addback Statutes, And Corporate Decisions, Obed Nana Buadi

Open Access Theses & Dissertations

This dissertation comprises three chapters examining how political risk and tax enforcement shape corporate investment decisions and firm value. The first essay investigates how firm-level political risk affects investment efficiency among U.S. firms. Using 40,215 firm-year observations spanning 2002-2022 and exploiting the Hassan et al. (2019) political risk index as a firm-specific measure, we find that political risk reduces investment efficiency exclusively through underinvestment - a one-standard-deviation increase corresponds to approximately $5.7 million in foregone annual investment for a median firm. Mediation analysis confirms that precautionary cash hoarding accounts for 31.8% of the effect, establishing uncertainty - rather than capital …

Transnational Indigenous Environmental Justice: A Distant Comparative Study Of Nepali And U.S. Environmental Policies And Counter-Archives In Technical Communication, Shankar Paudel

Open Access Theses & Dissertations

This dissertation investigates how institutional communication, state bureaucracy, and Indigenous sovereignty intersect within Rhetoric and Writing Studies (RWS) and Technical and Professional Communication (TPC). Current TPC research increasingly focuses on social justice; however, the field still lacks ethical frameworks to deal with the complicated dynamics of transnational Indigenous Environmental Justice Communication (IEJC). This study addresses this gap by examining how two distinct Indigenous communities - the Tharus of Chitwan, Nepal, and the Ysleta del Sur Pueblo Tigua Indians of El Paso, Texas - communicatively navigate, contest, and resist state environmental policies.

Grounded in decolonial Distant Comparativism, Mestiza Consciousness, Rhetoric of …

Voices Of Men In Diabetes Care: Evaluating Participant Satisfaction With A Men's Diabetes Management And Self-Care Program, Elida Herrera

Open Access Theses & Dissertations

Background: Hispanic populations in the US experience higher diabetes prevalence, yet Hispanic men participate in traditional diabetes education programs at lower rates than non-Hispanic White men and Hispanic women, in part because existing programs lack cultural and gender-relevant tailoring. To address this disparity, the Diabetes Garage (DG) program was developed for Hispanic men in Southwest Texas, leveraging car culture by using automotive maintenance analogies to illustrate diabetes self-management concepts to engage men. Purpose: To evaluate participant satisfaction with the DG program among cohorts participating across three predominantly Hispanic communities and to examine their personal opinions on their program experience.

The Mouse At The Border: Magic, Money, And Manufactured Identity, Ricardo Manuel Hinojosa

Open Access Theses & Dissertations

This thesis investigates the methods by which The Walt Disney Company constructs and negotiates representations of Latine, gender, and queer identities within contemporary animation, with a particular emphasis on Coco (2017), Encanto (2021), and Wish (2023). Through a critical and intersectional lens, this research posits that Disney strikes a balance between cultural specificity and global market appeal, often leading to representations that are visually elaborate yet narratively limited. Both Coco and Encanto showcase a significant engagement with cultural traditions and themes such as memory and generational trauma; however, they ultimately fall short of thoroughly addressing systemic issues like colonialism and …

Impact Of Campus Leadership Behaviors On Teacher Experiences With Burnout, Carmen Imai

Open Access Theses & Dissertations

Teacher burnout continues to be a significant concern in K-12 education, contributing to emotional exhaustion, decreased job satisfaction, teacher attrition, and negative impacts on student learning. While previous research has examined the causes and symptoms of burnout, less attention has been given to how teachers perceive the role of campus leadership in either mitigating or contributing to burnout experiences. The purpose of this qualitative phenomenological study was to explore how teachers who have experienced burnout perceive the role of campus administrators within that process. The study was guided by three research questions focused on teachers' experiences with burnout, perceptions of …

Microcosms & Warscapes, Heather J. Lathers

Open Access Theses & Dissertations

This poetry collection features sensory-centered writing and common objects, scenes, and interactions to authentically capture the multi-perspective and nuanced experiences of wartime. Detailed language is critical when poets become mouthpieces for those enduring war's pain. Focusing closely on items such as teacups, boots, bones, mud, rice, and rats creates a kind of intimacy not often found in war writing. Specific conflicts addressed include World War I, Vietnam, and The Cambodian Genocide. The poems here, in various forms and voices, aim to spotlight the lost, marginalized, abused, and forgotten-- the much-needed humanity war stories tend to neglect. Ultimately, these pieces seek …

Linguistic Experiences And Identity Of Mexican-Origin New Teachers In A Rural District In The U.S.-Mexico Frontera, Patricia L. Ocana

Open Access Theses & Dissertations

This qualitative study is developed with the understanding that the linguistic experiences of Mexican-origin new teachers are situated in the socially constructed Institutional Discourses of U.S. schools in la frontera. Discourses that have historically marked Spanish-speaking identities as deficient while privileging English-only norms. Furthermore, the four maestras in this study are considered active agents in their development as bilingual educators and creators of counter-Discourses that affirm the linguistic and cultural identities of their emergent bilingual students. This study looks at Mexican-origin bilingual educators' vivencias as assets that shaped their journeys into the education profession and continue to shape their pedagogical …

Interprofessional Education For Teachers: Exploring Adult Learning Of Collaboration Through Cultural-Historical Activity Theory, Berenice Peralta Matus

Open Access Theses & Dissertations

This qualitative study examines how participation in an Interprofessional Education (IPE) simulation event influenced participants' understanding of collaboration. Grounded in Cultural-Historical Activity Theory (CHAT), the study examined how participants made meaning of collaboration, and the barriers to collaboration and interdisciplinary work both at their graduate program and their work environment. Data was collected in three phases and included semi-structured interviews with teachers before and after the event, observation fieldnotes and video of the event. I analyzed the data using CHAT as the interpretative conceptual framework for thematic interpretation of concepts such as mediation, contradictions, division of labor, and activity systems. …

Enhancing Gender Congruence And Life Satisfaction In The Borderland Through Gender-Affirming Communication Services, Kimberley Ramirez

Open Access Theses & Dissertations

Transgender individuals frequently encounter barriers to accessing gender-affirming healthcare, particularly within marginalized borderland communities. Communication-based gender affirmation, including voice therapy and nonverbal communication training, remains an underexplored yet essential component of transgender health and psychosocial well-being. The purpose of this study was to examine the impact of gender-affirming communication services on voice-gender congruence and life satisfaction among transgender individuals living in the U.S.-Mexico borderland region. A single-subject experimental design (ABAB) was implemented with six participants initially enrolled in the study.

Comparative Case Studies Of How General Chemistry Ii Students Explain Entropically-Driven Phenomena, Raymundo Aragonez

Open Access Theses & Dissertations

Understanding how students conceptualize entropy remains a central challenge in chemistry education. Often referred to as a "driving force" of chemical reactions, the dispersal of energy as a process proceeds is indicative of a process's spontaneity or thermodynamic favorability. Students frequently default to discussing phenomena in deterministic terms, potentially reflecting the language choice and heuristics selected by the instructor such as "disorder". In this study, assessment prompts about entropy from a convenience sample of general chemistry textbooks were characterized as to their potential to elicit three-dimensional learning, and students' responses to assessment prompts from a curriculum aligned with three-dimensional learning …

Language Control Over Structural Representation In Bilinguals, Anahy Barragan-Diaz

Open Access Theses & Dissertations

In daily life, bilinguals sometimes speak each of their languages in situations where the other language cannot be understood. To avoid saying words in the wrong language in such situations, bilinguals inhibit lexical representations from the non-target language (Green, 1998). But do they inhibit structural representations? This study investigated how inhibitory control operates over structural representations in English-dominant Spanish-English bilinguals via a picture description task. An experimental group was asked to describe dative-eliciting pictures in English (Baseline Phase), followed by dative pictures in Spanish (Manipulation Phase), and once again dative pictures in English (Target Phase), while a control group followed …

We Are Still Lipan: Identity Erasure, Settler Colonialism, Historical Memory And The Persistence Of The Non-Reservation Lipan Apache, Freddy Cabral

Open Access Theses & Dissertations

This dissertation challenges the long-standing historical narrative that the Lipan Apache disappeared in the late nineteenth century. Instead, it argues that the non-reservation Lipan Apache survived through strategic adaptation, mobility, kinship networks, and cultural continuity across the United States-Mexico borderlands. By examining the Lipan experience under Spanish colonial rule, Mexican governance, the Republic of Texas, and the State of Texas, this study demonstrates that shifting political regimes consistently pursued Indigenous land, labor, and subordination through structures of settler colonialism and racial hierarchy. Using the frameworks of settler colonialism, white supremacy, genocide studies, oral history, and autoethnography, this dissertation shows how …

How To Make Tamales: Stories, Jeanette Colby

Open Access Theses & Dissertations

In all its intersectionality, I see my thesis as a female journey of identity and maturation. A common theme in my writing always leads back to my upbringing in some way; my history, memories, and beliefs inevitably plague the storytelling animal that lives within me. These different kinds of narratives represent all the parts of my identity. At the same time, the fictional scenes allow me to dramatize and interpret specific life events, while the mythic narratives provide a symbolic framework for exploring psychological and spiritual truths that might transcend conventional logic. Almost all of these pieces reflect various aspects …

The Creature From Space: A Science Fiction Musical, Monroe Nathaniel Oxley

Open Access Theses & Dissertations

My thesis examines how the musical The Creature from Space uses metatheatre, musical form, and science fiction to explore identity, conformity, and social control within a fictional 1950s Texas town. Centered on Lilly, a young woman struggling between loyalty to her hometown and the desire for personal freedom, the musical reimagines conventions of the Golden Age American musical while critiquing the ideological structures embedded within them. Drawing on works such as Oklahoma!, The Rocky Horror Picture Show, Schmigadoon!, Little Shop of Horrors, and Ride the Cyclone, the project examines how musical theatre constructs and reinforces social roles through performance. The …

The Moderating Role Of Cannabis Use Motives On The Relationship Between Intragroup Marginalization And Cannabis Use In Hispanic Emerging Adults, Austin Ray Vernon

Open Access Theses & Dissertations

Cannabis use has become increasingly normalized among emerging adults, yet associated risks to health remain a growing concern. Cannabis use among Hispanic populations has risen over the past decade, underscoring the need to examine culturally relevant factors that may influence use patterns and related harm. Intragroup marginalization, a culturally specific form of identity-based rejection from one's own ethnic group, may represent one such factor. The present study examined whether intragroup marginalization is associated with cannabis use outcomes and whether cannabis use motives moderate these associations. Participants were 358 Hispanic college students recruited from a U.S.-Mexico border university. Following informed consent, …

The Role Of Service-Learning & Critical Pedagogy In Student Empowerment Through Self-Consciousness, Democratic, And Culturally Responsive Education, Shahbaa Zaidan

Open Access Theses & Dissertations

This qualitative phenomenological research examines the role of service learning that is based on critical pedagogy in empowering students and developing identity and consciousness in a Hispanic-Serving Institution (HSI) on the United States-Mexico border found in South Texas. This study challenges the top-down paradigm, in which empowerment and learning are considered in view of the practices of educators, their teaching methods, and their impacts on student achievement. The research is bottom-up and student-centered. This research explores how students' experiences during service-learning courses shape their sense of identity, voice, and empowerment. Key theories include critical pedagogy (Freire), experiential learning (Dewey), transformative …

Language Attitudes In El Paso: Investigating Language Loyalty, Public Perception, And The Impact Of English-Only Policies, Dalton S. Ascone

Open Access Theses & Dissertations

Language attitude studies have been a vital aspect of Sociolinguistics research along the U.S.-Mexico border, with significant contributions having been made by Hugo Mejias and his colleagues in the Lower Rio Grande Valley (1986; 2003) and Hidalgo (1986) in Ciudad Juarez. However, there has been a lack of updated language attitude research in the region in recent decades, particularly in the city of El Paso, which, up to now, has not been the subject of a general language attitude survey. The present project seeks to investigate the language attitudes of bilingual Spanish-speakers living in the El Paso region through the …
