Coaching Bilingual Speech-Language Student Clinicians And Spanish-Speaking Caregivers To Use Culturally Adapted Ndbi Techniques For Autistic Preschoolers, Richelle R. Mcguire

Speech and Hearing Sciences ETDs

This study used a cascading coaching model to train bilingual speech-language pathology graduate students and Spanish-speaking caregivers to implement naturalistic developmental behavioral intervention (NDBI) strategies with autistic preschoolers. Two triads, each including a student clinician, minimally vocal child with autism, and caregiver, participated. A monolingual instructor coached student clinicians in culturally adapted NDBI techniques, who then coached caregivers in Spanish. A mixed methods approach evaluated outcomes through single-case experimental design and qualitative interviews. All adult participants increased their use of targeted NDBI skills, with large to very large effect sizes. Qualitative findings suggested areas for improvement (e.g., need for more …

Challenging The Universality Of Poplack’S Syntactic Constraints: Insights From Arabic-English Code-Switching Among Saudi Arabian Women, Sharifa Bahri

Linguistics ETDs

This study investigates the applicability of Poplack's (1980) syntactic constraints, the free morpheme constraint and the equivalence constraint, to Arabic-English code-switching among Saudi Arabian women. Based on 886 intra-sentential code-switching utterances drawn from naturalistic podcast speech, the analysis reveals substantial violations of both constraints: 306 utterances (34.5%) violated the free morpheme constraint, and 601 utterances (67.8%) violated the equivalence constraint, occurring across a wide range of syntactic categories. While violations of the free morpheme constraint were exclusively unidirectional, involving Arabic bound morphemes attached to English free morphemes, equivalence constraint violations were bidirectional, though predominantly shaped by Arabic grammar. Crucially, many …

Emotional Metaphors In Mandarin And English: Fear And Surprise, Jing Yang

Linguistics ETDs

This paper explores the relationship between emotion and experience from a cognitive perspective to fulfill two purposes. First, it seeks to identify the commonalities and differences in emotional metaphors across vastly different languages and the reasons behind these variations. Second, it aims to contribute to typological research in emotion studies beyond established areas such as color, time, and space using innovative approaches. Specifically, this study focuses on fear and surprise to categorize their source domains using lexical and corpus-based methods. Examples were collected from constructions and the corpus, and patterns of FEAR and SURPRISE metaphors in Mandarin were compared with …

In Silico Prediction Of Cytotoxic T-Cell Epitopes From Helicobacter Pylori Virulence Factors Using An Immunoinformatics Approach, Demy Valerie Chacon, Kiana Alika Co, Daphne Noreen Enriquez, Aubrey Love Labarda, Reanne Eden Manongsong, Edward Kevin B. Bragais

Biology Faculty Publications

Background: Helicobacter pylori infects approximately half of the global population, leading to gastric and duodenal ulcers. Despite the availability of antibiotics, challenges such as patient reluctance, high treatment costs, and antibiotic resistance limit their effectiveness, making vaccination a promising alternative. This study used immunoinformatics to identify candidate epitopes for a multiepitope vaccine construct against H. pylori.

Material and methods: The protein variability server was utilized for conservation analysis. The epitopes were screened for antigenicity, allergenicity, toxicity, cross-reactivity, and population coverage. Selected epitopes were docked with their corresponding human leukocyte antigen (HLA) alleles, and thermodynamic quantities were determined. Five virulence …

Improved Rational Approximations Of Pi, Nelson Carella

Publications and Research

The irrationality exponent of a real number α is defined by maximal value μ(α) ≥ 1 such that the inequality |p/q − α| < 1/qμ(α) is true for finitely many rational approxi- mations by relatively prime pairs p/q. The earliest result introduced the upper bound μ(π) ≤ 42 for the irrationality exponent of π. Subsequently, it was improved by many authors. The more recent result introduced the improved upper bound μ(π) ≤ 7.6063. This note introduces an improved irrationality exponent μ(π) ≤ 3. The optimal value is expected to be μ(π) = 2.

Rethinking The Applicability Of Section 8 Of The Canadian Charter For The Information Age And Beyond, François Tanguay-Renaud

All Papers

The Supreme Court of Canada’s interpretation of the right to be secure against unreasonable search and seizure guaranteed by section 8 of the Canadian Charter of Rights and Freedoms has remained fairly stable since the adoption of the Charter. Or at least, that is how the Court’s section 8 jurisprudence to date makes it seem. Yet, in some recent decisions dealing with digital communications and the internet—culminating in the 2024 case of R. v. Bykovets—the Court has, implicitly, brought into question the foundational principle based on which the right has historically been circumscribed. Or so I argue in …

Cultural Risk And Protective Factors Associated With Sexual Assault Among Hispanic And Non-Hispanic White Women, Daisy Ramos

Psychology ETDs

There is a paucity of research on sexual assault among Hispanic college women. Existing studies indicate that Hispanic college women report similar mental health sequelae as non-Hispanic White women following a sexual assault; thus, factors that protect or increase their risk is an area worthy of further investigation. Latino cultural values, such as familism, may serve as a protective factor for sexual assault among Hispanic college women, while acculturation with mainstream culture may function as a risk factor. This study examined whether ethnicity moderated the effects of cultural protective and risk factors on sexual assault experiences among Hispanic and non-Hispanic …

Some Corrections To The Record On Lemkin’S Early Years: The Evidence From Poland, Zachary Mazur

Genocide Studies and Prevention: An International Journal

This piece addresses some misunderstandings regarding Raphael Lemkin's early years in Poland, his influences and the development of his ideas. While discussing some of the extent published information, I point out what other archival documents from Poland and the League of Nations have to say about Lemkin's past. One of the main points is that Lemkin was an unreliable narrator on his own life, and this has caused confusion.

Arts & Literature: A Personal Reckoning: Taking Responsibility As A Perpetrator, Henry C. Theriault

Genocide Studies and Prevention: An International Journal

This autobiographical essay identifies three forces that shaped the author’s participation in the scholarly and political struggle against genocide and other mass violence and oppression. These include his status as the grandson of Armenian Genocide survivors, the fact that his father was killed in action in the US War of Aggression against Vietnam, and the bullying he experienced as a child and adolescent. It then pushes back against any sense of victimhood that has resulted from the combination of these forces, to recognize the author’s implication in perpetration of the US War of Aggression against Vietnam, which the author has …

Optimizing Distributed Boundary Exchanges For Benchmarks, Solvers And Sparse Matrix Operations, Gerald Collom

Computer Science ETDs

Boundary exchanges dominate the cost of both stenciled codes and those that rely on sparse matrix operations. The performance of large boundary exchanges is limited by synchronization overheads and injection bandwidth limitations. Irregular boundary exchanges incur additional overheads due to the large number of required messages. This thesis investigates multiple methods for improving the performance and scalability of both Cartesian and irregular boundary exchanges. Since boundary exchanges are typically performed iteratively, persistent communication presents an opportunity for optimization by sharing and amortizing setup costs. Partitioned communication is also explored to increase asynchrony, reducing bottlenecks from synchronization overheads and data congestion. …

Exploring Immune System Through Computational Modeling: A Comprehensive Study Of Lymph Nodes And Immune Response Scaling, Vaccine Efficacy, And Large-Scale Extreme First Passage Time, Jannatul Ferdous

Computer Science ETDs

The adaptive immune response is a complex defense mechanism that develops over time to recognize and eliminate pathogens with remarkable precision and durability. This dissertation investigates the dynamics, scaling, and efficiency of the adaptive immune response through a synthesis of computational modeling, mathematical analysis, and agent-based simulations. First, we analyze the topology of the lymphatic network and investigate the T cell search time to find the lymph node that is containing the matching dendritic cell. Second we show how the scaling of lymph node number and volume with body mass, leads to scale-invariant search times for T cells locating antigen-bearing …

“…Stay On It…”/A Theory///“Illumination Happens”//, Lara E. Goldmann

Art & Art History ETDs

“…stay on it…”/a theory///“illumination happens”// is a critical engagement with the work of contemporary Black artists Arthur Jafa and Adam Pendleton, explored through the lens of the Black radical tradition. Bridging aesthetics, politics, and history, the dissertation investigates how their visual, sonic, and conceptual practices articulate Black life, insurgency, and imagination.

Drawing on theorists such as Fred Moten, Sylvia Wynter, Hortense Spillers, Frantz Fanon, and Cedric Robinson, the study constructs a framework that considers Blackness as an ontological, social, and aesthetic force. It examines how Jafa and Pendleton unsettle dominant epistemologies, staging acts of refusal and creation that resonate within …

The Evolution Of Schooling: From Industrial Obedience To Techno-Autonomy, Seb Taylor, Ron Roberts Ii

Digital Laboratory: Publisher of Internet Journal

This paper examines the enduring architecture of the American education system as a mechanism designed for compliance, not creativity. Rooted in 19th-century industrial logic, the structure of schooling, its physical design, time constraints, and assessment methods, has remained largely static despite seismic cultural and technological shifts. Through historical analysis and contemporary critique, this work interrogates the persistence of standardized methods, institutional prestige, and top-down instruction as barriers to meaningful learning and value creation. Drawing from interdisciplinary research and live case studies, including Alpha School’s AI-powered, mastery-based model, the paper advances the concept of techno-education: a student-centered paradigm informed by feedback …

Who Benefits From Active Music Engagement During Cancer Treatment? Associations Of Sociodemographic Characteristics And Risk Factors With Moderators Of Intervention Effects., Steven J. Holochwost, Elizabeth Harman, Kristin Stegenga, Seethal A. Jacob, Sheri L. Robb

Manuscripts, Articles, Book Chapters and Other Papers

Young children and their parents experience frequent and repeated exposure to potentially traumatic events during treatment for cancer. Active Music Engagement (AME) is a dyadic music therapy intervention that has been found to mitigate traumatic stress symptoms among parents who screened high for traumatic stress symptoms (TSS) and reported higher levels of child distress with cancer-related hospitalizations/treatment (child distress). The current study examined sociodemographic characteristics and risk factors that were associated with higher levels of parent TSS and child distress as a means to identify families that may benefit most from AME in the future. Data were collected from the …

Hidden Struggles, Shining Leaders: Black K–12 Leaders Navigating Microaggressions While Leading Predominantly White Or Majority-Minority Schools, Yinka Dallas

LMU Theses and Dissertations

This qualitative narrative study explored the lived experiences of eight Black educational leaders navigating microaggressions in predominantly White or majority-minority K–12 school settings in Southern California. Framed by Critical Race Theory (CRT) (Crenshaw, 1989; Ladson-Billings, 1998; Solórzano, 1998), the conceptual framework of microaggressions (Sue, 2010; Sue et al., 2008, 2007), and informed by the historical displacement of Black educators and leaders following Brown v. Board of Education (1954), the study examined how participants perceived and responded to microaggressions, as well as the reported psychological and physiological toll of these experiences, and strategies employed to address, cope with, and disrupted incidents …

Making The Macc: Communities Of Practice And Cultural Citizenship In Austin, Texas, Cassie Lynn Smith

Anthropology ETDs

Meaningful community engagement is a challenge for local governments without a thorough understanding of constituents’ histories and their relationship with City government. This dissertation investigates the City of Austin’s (COA) Emma S. Barrientos Mexican American Cultural Center (MACC) in Austin, Texas, to understand how this culture and arts institution engages with and is influenced by its patrons. This study analyzes the role of the MACC’s community of practice (Lave and Wenger 1991)—an evolving group of educators, activists, artists, and COA staff—in shaping public policy and educational programming as well as creating places of belonging for marginalized people in the city. …

Inequality And Covid Risk At School: Racial Disparities In Indoor Density, Vaccination Rates, And Consequences For Absenteeism, Michael C. Quinn, Michah W. Rothbart, Amy Ellen Schwartz, Brian Elbel

Center for Policy Research

During the COVID pandemic, schools were widely believed to be a venue that facilitated disease transmission. While some worried Black and Hispanic students would disproportionately face greater risk of COVID exposure at school (school COVID risk) – given well-documented racially disparate school environments and resources – little empirical evidence exists documenting or refuting potential disparities in school COVID risk. This paper begins to fill this gap by examining racial disparities in the school environments that contribute to COVID risk at school—specifically, vaccination rates and classroom space per pupil (indoor density) - in New York City elementary schools. We then document …

Microneedle-Based Lc-Ms/Ms Profiling Of Dermal Interstitial Fluid Reveals Early Lipid Dysregulation Contributing To Painful Neuropathy In Prediabetic And Type 2 Diabetic Rats, Srinivasa Rao Gadam

Biomedical Sciences ETDs

Painful diabetic neuropathy (PDN), a complication of type 1 and type 2 diabetes, also occurs in obesity and prediabetes, with dyslipidemia as a modifiable risk factor. The distal-to-proximal neuropathy pattern and length-dependent intraepidermal nerve fiber loss suggest peripheral contributions. We hypothesized that elevated neurotoxic lipid intermediates—diacylglycerols (DAG), free fatty acids (FFA), and acylcarnitines (CARs)—in the dermal interstitial fluid (ISF) drive metabolism-associated hyperalgesia in prediabetic and diabetic rats. Using a microneedle array (MIA) with LC-MS/MS, we profiled ISF and serum lipids from high-fat diet (HFD) and HFD + streptozotocin (STZ) rat models alongside Hargreaves testing. ISF lipid changes appeared earlier (weeks …

The Isoperimetric Inequality For Asymptotically Cat(0) Groups, Edric D. Dabu

Master's Theses

An asymptotically CAT(0) space is one where every ball of radius r is f(r)-CAT(0) for a fixed sublinear function f. An asymptotically CAT(0) group Γ is a group which acts properly and cocompactly by isometries on an asymptotically CAT(0) space X. Fix x0 ∈ X, choose D > 0 such that X = S γ∈Γ �� γ · B �� x0, D 3 ?? , define A = {a ∈ Γ : d(x0, a · x0) ≤ D + 1}, and let R be the set of reduced words in A of length at most 10 that represent the identity in …
