Language Barriers In Accessing Healthcare Services For Refugees In The United States, Sadaf Khuram

Communication & Theatre Arts Theses

Accessing healthcare is a pivotal aspect of refugees' integration into their host countries and significantly impacts their long-term health outcomes. The literature emphasizes the critical role of language proficiency in overcoming communication barriers within healthcare settings. This thesis, however, challenges the assumption that addressing language barriers alone is universally sufficient. It argues that the importance of language solutions is context-dependent, varying with the design of healthcare systems and the diverse needs and backgrounds of refugees. In some cases, focusing primarily on language barriers can divert resources from other critical areas, particularly when healthcare facilities have limited capacities or when services …

“We Are Trans, But We’Re Not Transitional”: Exploring Safety, Place, And Space In The Lives Of Transgender Individuals In Southeastern Virginia, Susana Avalos

Sociology & Criminal Justice Theses & Dissertations

In general, little research exists on trans people’s spatial experiences despite space being highly relevant to their experiences of violence and perceptions of safety. To date, two criminological studies have examined LGBTQ people’s fear of crime in relation to public or private places and spaces. This is in stark contrast to the sizable place and space literature on cisgender men and women. These topics from the perspectives of trans people are underexplored primarily because most criminological research has historically upheld binarized understandings of gender. Safety should not be privileged or limited to certain groups, individuals, or spaces. Instead, safety should …

Effect Of Moderate Decrease In Contractility On Epithelial Cell-Cell Contacts Under External Stretch, Saika Sharmin

Mechanical & Aerospace Engineering Theses & Dissertations

Epithelial tissues are characterized by extensive cell–cell contacts and often subject to stretch during normal function. Cell-cell contact adhesion strength maintains mechanical continuity from cell to cell. Mechanical forces exerted by cells via actomyosin contractility are known to strengthen cell-cell adhesions to a certain extent. While it is known that a large decrease in contractility causes cell-cell contact rupture due to weakened adhesions, it is unclear how a moderate reduction in contractility affects cell-cell junction stability. Here, we studied how a moderate inhibition of non-muscle myosin II (NMII) affects the integrity of epithelial cell-cell contacts, especially when subject to the …

The relationship between flux expulsion and flux trapping sensitivity to the metallurgical state of 1.3 GHz and 3.0 GHz SRF niobium cavities fabricated from standard and cold-worked Nb sheets and subjected to various heat treatments has been studied. Flux expulsion increased with higher heat treatment temperature in all cavities. Nb cavities made from cold-worked sheets showed better flux expulsion after 800 ◦C/3 h compared to the standard SRF-grade Nb cavities. Similar flux expulsion was observed after annealing at …

Exploring The Relationship Between Cannabis Use Motives And Readiness To Change Among Young Adult College Students, Emma Kathryn Rawls

Psychology Theses & Dissertations

Cannabis use among young adult college students has risen steadily over the past decade, raising concerns about the associated health, academic, and psychological consequences. While cannabis use motives and readiness to change have each been linked to use patterns and outcomes, limited research has examined how these factors interact. The current study investigated whether readiness to change, based on the Transtheoretical Model (TTM), moderates the relationship between cannabis use motives and cannabis-related consequences as well as past-30-day use frequency. A sample of 100 college students 18-25 years old (M_age = 20.08, SD = 2.12; 67% female; 55.0% Black or …

Computational Investigation Of Energetic Materials: Influence Of Electronic And Steric Properties On Sensitivity And Decomposition Mechanisms, Elizabeth Ruth Zengel

Chemistry & Biochemistry Theses & Dissertations

Developing novel high energy density materials (HEDMs) requires knowledge of the causes and mechanisms of detonation. These chemical events are almost instantaneous and involve the release of a large amount of energy, which limits the experimental studies that can be performed on them. Computational methods including density functional theory (DFT) and molecular dynamics (MD) simulations have been used to investigate trigger bonds, those which break to initiate detonation. These bonds are commonly found within explosophores, substituents that increase the explosive potential of a molecule.

The Wiberg bond index (WBI) is an estimation of orbital overlap and bond strength between two …

Service With A Smile Or Salesperson Mirroring? Understanding The Flow Of Emotional Contagion In Sales Encounters, Vinh Quoc Trong Luong

Theses and Dissertations in Business Administration

This study examines the directionality of emotional contagion in sales interactions, addressing a critical gap in understanding whether emotions flow primarily from the salesperson to the customer, from the customer to the salesperson, or bidirectionally. While prior research emphasizes customer-driven emotional flow or bidirectional alignment, this study challenges these assumptions by employing categorical Cross-Recurrence Quantification Analysis (CRQA) to assess temporal emotional synchronization in sales dialogues. Leveraging automated sentiment analysis and multi-agent AI evaluation for performance metrics, the research analyzes 166 sales interactions to quantify emotional influence dynamics. Results reveal that salespeople predominantly lead emotional exchanges, exhibiting stronger and more stable …

Sociology & Criminal Justice Theses & Dissertations

The founder of the Center for the Study of Social Policy in Washington DC, Tom Joe (1987) released an article examining economic disparities between Black and White Americans. Across the measures of income, poverty and unemployment rates, Black Americans were found to be at an economic disadvantage. According to current data published by the U.S. Department of Commerce (2018), the economic wealth gap has remained unequal. Prior research examining racial inequality has found Protestantism to be a foundation from which Americans form their ideologies about social issues (Hunt, 2007; Edgell & Tranby, 2007; Taylor & Merino, 2011). Data provided by …

The Effects Of The Chief Information Officer’S Presence And Tenure On Financial Performance, Xuemei Li

Theses and Dissertations in Business Administration

CIOs should be at the core of the organization. They play more and more critical roles in organizations. However, CIOs have not been paid enough attention in many firms. This can be partially observed in a lack of studies about CIOs, for instance, how CIOs influence the organizations, and how organizations' settings influence the CIOs. Technical initiatives or innovations may be the bridge between CIOs and firm performance. Different theories have been employed concerning CIOs, innovations, and firm performance. For instance, the resource-based view (RBV) has served as a theoretical foundation in related studies.

Drawing on RBV, attention-based view (ABV), …

Examining How Self-Regulated Learning Professional Development Affects Teacher Srl Knowledge, Beliefs, And Practices, Stephanie Greenquist-Marlett

STEMPS Theses & Dissertations

Self-regulated learning (SRL) strategies promote valuable student learning outcomes including academic achievement and lifelong learning (EU Council, 2002). Teachers have an opportunity to cultivate student SRL development within their classrooms (Azevedo et al., 2008). While teachers believe in the benefits associated with SRL promotion (Spruce & Bol, 2014), their positive attitudes are not often supported by adequate knowledge of SRL strategies. This leads to a lack of self-efficacy for developing SRL instruction in classrooms (Dignath & Büttner, 2018; Zimmerman et al., 1996). SRL-based professional development (PD) interventions have demonstrated their effectiveness for increasing teacher SRL instruction and implementation (Cleary et …

The Influence Of Monsoon Variability On The Circulation Of The Near-Surface Indian Ocean And The Depth-Integrated Chlorophyll, Marufa Ishaque

OES Theses and Dissertations

The Indian Ocean experiences a strong semiannual reversal of monsoon winds, which determines the weather and climate of Asia, including freshwater fluxes between the atmosphere, land, and ocean. Studies and model projections suggest that the timing and intensity of the seasonal monsoon have already started to change, with more dramatic changes likely in the future. However, the impact of these changes on the Indian Ocean circulation system, including the inter-basin salt/freshwater transport between the Bay of Bengal and the Arabian Sea, remains unclear. To better understand how monsoon variability affects Indian Ocean circulation patterns, a Regional Ocean Modeling System simulation …

Enhancing Data Usability For People With Visual Impairments, Yash Prakash

Computer Science Theses & Dissertations

Human-Data Interaction (HDI) focuses on how individuals engage with, analyze, and extract insights from data. For blind and visually impaired (BVI) users, interacting with data, whether searching for relevant information from structured data (e.g., web data items) or interpreting visualizations to draw insights (e.g., data charts), presents significant challenges. These challenges arise from the complexity and sheer volume of data which cannot be effectively handled by assistive technologies like screen readers and screen magnifiers. Despite its importance, data usability, the ease, efficiency, and satisfaction with which BVI individuals can interact with the data, has received less attention compared to data …

Empowering The User Through Inclusive Technical Writing, Robert Enriquez

English Theses & Dissertations

This thesis examines the issues in technical writing due to a disconnect between writer and reader/user. I am basing this study on my real-life job. I am a manager at a well-known sneaker retailer. In August 2024, there was a Workforce Management (WFM) software that the sneaker retailer launched in the retail stores. The WFM itself was glitched and unfinished. Not much disclaimer, training or preparation was given other than these procedural documents the sneaker retailer gave. If all the store managers had to depend on was technical documentation to prepare for this already glitched WFM, then I argue there …

Using Radium Isotopes To Compare Nutrient Inputs Via Submarine Groundwater Discharge To Offshore Export On The West Florida Shelf, Andrew L. Lindgren

OES Theses and Dissertations

Radium isotopes have been used to trace submarine groundwater discharge (SGD) and associated nutrient and metal inputs into the coastal ocean. They have also been used to estimate rates of diffusive mixing and export fluxes of dissolved constituents offshore. However, use of both approaches in tandem to determine the fate of groundwater inputs after they enter the coastal ocean is still relatively unexplored. Radium isotopes and nutrients were measured in two cross-shelf cruises on the West Florida Shelf in different seasons and in quarterly sampling of offshore wells. Through 226Ra mass balance and 223Ra-derived diffusive mixing rates, inputs of nutrients …
