Omnichannel Identity Dimensions and Their Differential Impact on Customer–Brand Relationships: A Comparative Analysis of South Korean Retailers
No full textThis study investigates how a consistent brand identity across multiple channels influences customer experiences and relationship development in South Korean retailers’ omnichannel strategies. To address the fundamental challenge of balancing brand consistency with channel-specific customization, we developed a comprehensive omnichannel identity framework through rigorous measurement development and factor analysis. This framework comprises three empirically validated dimensions: trendiness, reliability, and usability. Data collected from 994 customers of two leading South Korean retailers were analyzed using structural equation modeling, revealing that these omnichannel identity dimensions exert differential influences on cognitive and affective brand experiences, which subsequently mediate the development of customer–brand relationships. Notably, the results demonstrated significant variance in the impact of identity components between retailers—trendiness and reliability emerged as primary drivers of brand experiences for Retailer A, while usability constituted the dominant factor for Retailer B. This study contributes to sustainable retail theory by empirically validating the multidimensional conceptualization of omnichannel identity and its selective influence on customer perceptions within an environmental responsibility context. The findings provide strategic guidance for retailers seeking to develop distinctive brand identities across channels in the highly digitalized South Korean consumer market, ultimately enhancing brand equity and sustainability performance through stronger customer–brand relationships that promote environmentally conscious consumption behaviors.Marketin
Transforming PTSD Care: A Systematic Review of Telehealth Intervention for U.S. Veterans [paper]
No full textPost-traumatic stress disorder is a significant mental health condition affecting 24.5 % of the United States military veterans (Sadeghi et al., 2021). It contributes to reduced quality of life, impaired functioning, and an overall feeling of detachment from one’s surroundings (Sadeghi et al., 2021). The systematic review aimed to determine whether telehealth-based trauma-focused therapy yields comparable results to adherence and symptom reduction, compared to conventional in-person therapy for veterans with post-traumatic stress disorder. The literature search was performed using the MEDLINE Complete, APA PsychArticles, and CINAHL databases to identify relevant peer-reviewed studies. Findings across multiple studies revealed that telehealth-based interventions produced comparable or superior outcomes in PTSD symptom reduction and treatment adherence. The results suggest that telehealth-based trauma-focused therapy is an effective alternative for accessible healthcare for veterans experiencing barriers to in-person mental health care. Ongoing research is essential to enhance implementation approaches and ensure fair access for all veteran groupsNursin
A Unified Autotuning Framework for Deep Learning on the Cloud-Edge Continuum
No full textDeep neural networks (DNNs) underpin modern applications in computer vision, natural language processing, and generative AI. With the proliferation of Internet-of-Things (IoT) devices and embedded sensors, large-scale DNNs are increasingly being deployed on Edge platforms to perform inference in latency-sensitive applications such as mobile robotics, autonomous vehicles, and smart infrastructure. However, Edge devices are inherently constrained by limited compute capability, memory, and power budgets, making automated performance optimization, particularly machine-learning-driven autotuning, critical for efficient deployment.
While numerous techniques have been proposed for DNN optimization, autotuning for the Edge introduces unique challenges. These include reasoning across disjoint optimization spaces (e.g., network architecture and low-level code parameters), making accurate power–performance trade-offs under tight energy constraints, and reducing the tuning overhead to meet real-time or near real time deployment requirements.
This dissertation presents the design and implementation of AutoEdge, a lightweight, end-to-end autotuning framework that addresses these challenges. AutoEdge introduces several innovations: (i) joint exploration of neural architecture and compiler optimization spaces using a feature-fusion technique; (ii) a hybrid, two-stage autotuning strategy that employs machine-learning-based search-space pruning and selective hardware invocation to drastically reduce tuning time; and (iii) a multi-objective heuristic search that explicitly models performance, power, and energy efficiency trade-offs.
Together, these capabilities make AutoEdge an adaptive and scalable autotuning solution for DNN inference on heterogeneous Edge devices. Experimental evaluations on representative Edge platforms and widely used DNN benchmarks demonstrate that AutoEdge achieves superior performance-efficiency trade-offs while reducing tuning overhead by up to an order of magnitude compared to existing methods.Computer Scienc
From Nourishment to Deficiency: How Colonization Reshaped Native American Women's Dietary Health
No full textThis capstone literature review explores how colonization changed the nutritional health of Native American women through the disruption of traditional food systems. By using a decolonial and biocultural framework, it combines paleopathological, anthropological, and policy-based literature to analyze nutrition and health transitions across pre- and post-contact periods. Pre-contact evidence highlights the critical role Indigenous women played in sustaining nutritionally rich diets and ecological balance, while post-contact osteological and historical data demonstrates a stark increase in malnutrition, disease, and reproductive stress throughout the aftermath of European colonization. When interpreted within colonial power dynamics, these biological stress markers illustrate how structural violence became prevalent across generations. This review connects historical malnutrition and forced relocation to modern health inequities such as cardiovascular disease, diabetes, and maternal mortality. It further examines how modern federal food programs, including the Food Distribution Program on Indian Reservations (FDPIR) and the Supplemental Nutrition Assistance Program (SNAP), perpetuate colonial efforts of dependency, while innovative tribal initiatives such as the Healthy Diné Nation Act (HDNA) aim to reinstate food sovereignty and self-governance. Ultimately, this review demonstrates that Native health must be understood as an enduring relationship between the body, culture, and land; one continuously disrupted by colonial intrusions yet constantly revived through resilience, sovereignty, and knowledge. By centering the focus on Native American women’s lived experience and leadership, this research emphasizes how reclaiming traditional food systems strengthens Indigenous health and supports holistic healing.Anthropolog
Characterization of Asphalt Binder and Mixture for Enhanced Railway Applications
No full textAlthough asphalt mixtures can be applied to railway tracks due to their viscoelastic properties, caution is required, as their ductility and brittleness are highly sensitive to temperature variations. In recent years, interest in the application of asphalt in railway infrastructure has increased, driven by the development of modified mixtures and the broader availability of performance-enhancing additives. Additionally, evaluation methods for railway tracks should be adapted to account for the distinct loading mechanisms involved, which differ from those of conventional roadways. In this study, the comprehensive properties of asphalt binders, mixtures, and testing methods—including physical and engineering characteristics—were assessed to improve the performance of asphalt concrete layers for potential applications in railroad infrastructure. The results of this study indicate that (1) the higher the performance grade (PG), the higher the indirect tensile strength (ITS) value achieved by the 13 mm mixture using PG76-22, which is higher than that of the PG64-22 mixture. This indicates that higher PG grades and modification contribute to improved tensile strength, beneficial for upper layers subjected to dynamic railroad loads. (2) The tensile strength ratio (TSR) increased from the unmodified mixture to over 92% in mixtures containing crumb rubber modifier (CRM) and styrenic thermoplastic elastomer (STE), demonstrating enhanced durability under freeze–thaw conditions. (3) Wheel tracking test results showed that modified mixtures exhibited more than twice the rutting resistance compared to PG64-22. The 13 mm aggregate mixtures also generally performed better than the 19 mm mixtures, indicating reduced permanent deformation under repeated loading. (4) It was concluded that asphalt is a suitable material for railroads, as its overall characteristics comply with standard specifications.Engineering Technolog

Fredericksburg Germans and Indigenous Comanches: Cultural Exchange on the Texas Frontier, 1846-1855
No full textThe period of relatively peaceful, mutually beneficial relations between the Comanche peoples and German settlers of Fredericksburg, Texas is sometimes described as an ""anomaly"" among the histories of European-colonial and Indigenous American contact. This period serves to challenge our typical understanding of colonial power dynamics along the mid-19th-century Texas frontier. The period was characterized by a mutual recognition of both societies' capacity for warfare, as well as a pervasive sense of desperation and aversion to violence. This dynamic led to the negotiation of formal terms for peace. The Meusebach-Comanche treaty of 1847, facilitated by the concerted efforts of German settlers and Penateka Comanche leaders, ushered in a period of peaceful coexistence between the Fredericksburg Germans and Comanche peoples of the Texas Hill Country. This treaty not only ensured peaceful coexistence but also facilitated remarkable cultural exchange through cooperation and free trade. Among these cultural products are numerous unique items, including the art of Friedrich Richard Petri, as well as the German-Comanche language translation glossaries by Heinrich Berghaus and Emil Kriewits, the latter of whom lived with and acculturated among the Penateka in order to serve as an intermediary. Beyond these historical artifacts, a vivid memory of the Comanche persists in the oral history of Fredericksburg, best exemplified by the annual tradition of the "Osterfeuers," said to have been appropriated from an Indigenous practice of lighting bonfires atop the hills around Fredericksburg that became associated with the holiday of Easter.World Languages and Literature
Disability Identity, Age, and Grit in University Students: An Examination of Relationships Between Constructs
No full textAs the number of university students with disabilities and mental health conditions continues to rise, understanding the factors that influence their academic success is increasingly critical. This study explores the relationship between disability identity development and grit—defined as perseverance and passion for long-term goals—among adult learners with disabilities in higher education. Grounded in self-determination theory (SDT), the disability identity development model (Forber-Pratt & Zape, 2017), and grit theory (Duckworth et al., 2007), the research investigates how age, age of diagnosis, and type of disability influence disability identity and grit, and whether disability identity mediates these relationships.
Using a correlational design and structural equation modeling (SEM), data were collected from 295 students registered with Disability Services at a large public university in Texas. Participants completed the Disability Identity Development Scale (DIDS), the Short Grit Scale (Grit-S), and demographic questions. Results revealed that disability identity significantly predicted grit, and that students with multiple disabilities—particularly those with sensory impairments—reported stronger disability identities. While age positively correlated with grit, neither age nor age of diagnosis significantly predicted disability identity. Notably, disability identity partially mediated the relationship between disability type and grit, suggesting that a strong disability identity may buffer the negative impact of having multiple disabilities on perseverance.
This study contributes to the literature by highlighting the motivational role of disability identity in fostering grit and resilience among students with disabilities. Findings underscore the importance of identity-affirming practices and inclusive support systems in higher education, particularly for students with complex or intersecting disability experiences. Implications for theory, policy, and practice are discussed, along with recommendations for future research on identity development and academic persistence in marginalized student populations.Counseling, Leadership, Adult Education, and School Psycholog
Between, Within, and Beyond: Weaving Neurodivergent Journeys through Nepantla toward Conocimiento
No full textThis dissertation explores the lived experiences of neurodivergent adults of color, including myself, as we navigate identity formation within Nepantla—the liminal, in-between space where multiple identities converge, as conceptualized by Gloria Anzaldúa. Grounded in Chicana feminist theory and informed by testimonio, Nepantla, and the axis of neurodivergence, this study expands understandings of identity by centering the intersections of race, culture, and gender. Employing a social cartography methodology that integrates autoethnography, photovoice, and collective testimonio to collect and create observables, I invite co-creators to map, narrate, and visually represent their journeys through moments of tensions, marginalization and belonging. The findings reveal that co-creators experience Nepantla as both a site of fragmentation and of profound creativity, using storytelling and art-making (including milagros, drawings, and digital works) to articulate, reclaim, and transform their identities. The process foregrounds collective meaning-making, highlighting the tensions of navigating dominant narratives while fostering agency, joy, and connection. Through poetic transcription, thematic, and visual analysis, this work demonstrates that social cartography is not only a methodology, but a transformative tool that enables new ways of being and knowing within liminal spaces. By centering voices often silenced or pathologized in and by traditional and positivist inquiry and research methods, this dissertation affirms the power of collaborative inquiry, storying and visual practice as resistance, survivance, and a path toward Conocimiento (self-knowledge).Counseling, Leadership, Adult Education, and School Psycholog
