Interactional Challenges For Non-Native Speakers Of English In Emergency Telephone Calls, Angela Garcia May 2022

Interactional Challenges For Non-Native Speakers Of English In Emergency Telephone Calls, Angela Garcia

Natural & Applied Sciences Faculty Publications

This paper investigates interactional challenges experienced in calls to emergency services with native English speaking (NS) call takers and non-native speaking (NNS) callers. Case studies of three problematic NNS/NS calls from a collection of emergency service calls were conducted using a conversation analytic approach. These calls were selected from publicly available recordings which were made by callers who were hearably NNS of English. The analysis shows how accents, grammatical and other linguistic choices led to related challenges in the pragmatics of communication (including procedures for sequential organization such as adjacency pairs, repair initiation, confirmation requests, presequences and story solicits). Routine …

As coral reef condition and sustainability continue to decline worldwide, losses of critical habitat and their ecosystem services have generated an urgency to understand and communicate reef response to management actions, environmental contamination, and natural disasters. Increasingly, coral reef protection and restoration programs emphasize the need for robust assessment tools for protecting high-quality waters and establishing conservation goals. Of equal importance is the need to communicate assessment results to stakeholders, beneficiaries, and the public so that environmental consequences of decisions are understood. The Biological Condition (BCG) model provides a structure to evaluate the condition of a coral reef in increments …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This paper studied the influence of pre-saturated lightweight sand (LWS) on the mechanical and microstructural properties of UHPC cast with steel fiber alignment. The changes in hydration kinetics, porosity, nano-mechanical, and mechanical properties were studied. The LWS was used at 0–50% replacement volumes of total sand. Predominant fiber alignment was favored through a flow-induced casting method during casting of flexural prisms. Experiment results showed that the 28-d autogenous shrinkage was decreased from 450 to 275 μm/m with the LWS content increasing from 0 to 50%. The addition of 20% LWS led to maximum increases of 15%, 15%, and 20% in …

The Impact Of Covid-19 On Nurse Leadership Characteristics, Karen Fowler, Leslie K. Robbins

Nursing Faculty Publications

Background: Nurse leaders are vital for improving nursing efficiencies and the quality of care that they provide during a crisis and its aftermath. The value of positive leadership characteristics has never been more critical than during the COVID-19 pandemic. Functioning in a crisis mode required nurse leaders to demonstrate the necessary skills for clear communication and solid leadership. Therefore, nursing leadership, especially in emergencies such as the COVID-19 pandemic, needs to be transformative in the sense that leaders are informational, motivating, and able to advance the organization, notwithstanding a global pandemic. Timely leadership research during and after COVID-19 is crucial …


Renal Angina Index As A Predictor Of Acute Kidney Injury In Critically Ill Children, Athul Shelly Kooliyath May 2022

Renal Angina Index As A Predictor Of Acute Kidney Injury In Critically Ill Children, Athul Shelly Kooliyath

Master of Medicine in Paediatrics and Child Health

Background: Acute kidney injury is associated with increased morbidity and mortality in hospitalized children. In the critically ill,DR WILLIAM M MACHARIA acute kidney injury (AKI) is prevalent and difficult to diagnose. Using conventional methods, AKI is often missed thus delaying the diagnosis up to 48 hours after initial injury. Though some biomarkers that identify AKI early have been identified, they may still be insufficient due to prohibitive costs. Renal angina index is used to identify ongoing renal injury. It is a product of the clinical state and the estimated glomerular filtration rate (eGFR) of a patient during admission to a …

Deep Learning In Sports Prediction, Fan Lee

Computer Science Honors Theses

Sports prediction has always been an interesting problem in the entertainment industry. Many data scientists have come out different methods on this problem. We hope to see how well a neural network model can predict an individual game outcome and the final ranking on NBA data. We examined the possibility of different unbiased deep learning models can perform as well as other mathematics methods. We were also looking for what types of data are more influential for the models. Then, we can make some assumptions on our models and the other sports prediction methods.


Fish Community Assembly At Multiple Spatial Scales In East Texas Streams, Jake R. Swanson May 2022

Fish Community Assembly At Multiple Spatial Scales In East Texas Streams, Jake R. Swanson

Electronic Theses and Dissertations

Stream communities are structured by environmental processes that vary in strength across different spatiotemporal scales. Therefore, revealing how stream fish communities are influenced by environmental gradients may clarify how communities respond to disturbance associated with anthropogenic change. I investigated the relative role environmental variables play in the processes that structure the taxonomic and functional diversity of stream fish communities, as well as historical trends in occurrence and local habitat associated with a species of greatest conservation need within east Texas. The results of this study indicate that stream sites with more habitat complexity and stability support a more taxonomically and …

Covid-19’S Effects On Mortality Salience, Death Anxiety, And Worldview Defense, Sahvannah K. Shavers May 2022

Covid-19’S Effects On Mortality Salience, Death Anxiety, And Worldview Defense, Sahvannah K. Shavers

Electronic Theses and Dissertations

Since late-2019, the world has been trying to overcome an invisible killer: COVID-19. With near constant reminders of the virus the knowledge that a tiny viral particle has potential to harm or even kill has become overwhelming for many. Terror Management Theory (TMT) suggests that when individuals are reminded of their own death people take part in culturally appropriate activities and defend their own culture as ways to alleviate this increased death anxiety. The current study aims to identify whether 1) reminders of COVID-19 prime death thoughts, 2) reminders of COVID-19 increase death anxiety, and 3) increased death anxiety from …


Brignoni-Ponce And The Establishment Of Race-Based Immigration Enforcement, Isabel Skilton May 2022

Brignoni-Ponce And The Establishment Of Race-Based Immigration Enforcement, Isabel Skilton

Washington International Law Journal

United States v. Brignoni-Ponce solidified the racist enforcement of United States immigration laws by allowing “Mexican appearance” to be a factor forming reasonable suspicion in a roving patrol. The United States Supreme Court rationalized race-based immigration enforcement by relying on erroneous immigration demographics and a misconstrued notion of serving the public interest. This comment demonstrates that the rationales provided by the Supreme Court are illogical, discriminatory, and harmful to communities of color. This comment analyzes the impacts of race-based discrimination and provides alternatives which may cabin the impact of Brignoni-Ponce. Aside from overruling Brignoni-Ponce in its entirety, a probable cause …


On Uniqueness And Stability For The Boltzmann-Enskog Equation, Martin Friesen, Barbara Ruediger, Padmanabhan Subdar May 2022

On Uniqueness And Stability For The Boltzmann-Enskog Equation, Martin Friesen, Barbara Ruediger, Padmanabhan Subdar

Faculty Publications

The time-evolution of a moderately dense gas in a vacuum is described in classical mechanics by a particle density function obtained from the Boltzmann-Enskog equation. Based on a McKean-Vlasov equation with jumps, the associated stochastic process was recently constructed by modified Picard iterations with the mean-field interactions, and more generally, by a system of interacting particles. By the introduction of a shifted distance that exactly compensates for the free transport term that accrues in the spatially inhomogeneous setting, we prove in this work an inequality on the Wasserstein distance for any two measure-valued solutions to the Boltzmann-Enskog equation. As a …


Patterns Of Choice Adaptation In Dynamic Risky Environments, E Konstantinidis, J L. Harman, C Gonzalez May 2022

Patterns Of Choice Adaptation In Dynamic Risky Environments, E Konstantinidis, J L. Harman, C Gonzalez

Faculty Publications

An important aspect of making good decisions is the ability to adapt to changes in the values of available choice options, and research suggests that we are poor at changing behavior and adapting our choices successfully. The current paper contributes to clarifying the role of memory on learning and successful adaptation to changing decision environments. We test two aspects of changing decision environments: the direction of change and the type of feedback. The direction of change refers to how options become more or less rewarding compared to other options, over time. Feedback refers to whether full or partial information about …

Impact Of Sex On Proliferation And Maturation Of Primary Isolated Myoblasts, Elsa M. Bean May 2022

Impact Of Sex On Proliferation And Maturation Of Primary Isolated Myoblasts, Elsa M. Bean

Biomedical Engineering

Peripheral arterial occlusive disease (PAOD) is caused by the buildup of atherosclerotic plaque causing restriction in blood flow in tissue, known as ischemia. It affects 8 million people in the United States and can hinder daily life through the onset of symptoms such as intermittent claudication and in extreme cases ulcers and gangrene. Surgical revascularization is not accessible to certain patient populations, such those of advanced age, highlighting a need for alternative therapies. For example, naturally occurring bypass arteries, called collateral blood vessels, can remodel and enlarge to bypass the occlusion. This process, known as arteriogenesis, has been studied as …

Oncostatin M (OSM) is an immune cell-derived cytokine that is upregulated in adipose tissue in obesity. Upon binding its receptor (OSMR), OSM induces the phosphorylation of the p66 subunit of Src homology 2 domain-containing transforming protein 1 (SHC1), called p66Shc, and activates the extracellular signal-related kinase (ERK) pathway. Mice with adipocyte-specific OSMR deletion (OsmrFKO) are insulin resistant and exhibit adipose tissue inflammation, suggesting that intact adipocyte OSM–OSMR signaling is necessary for maintaining adipose tissue health. How OSM affects specific adipocyte functions is still unclear. Here, we examined the effects of OSM on adipocyte lipolysis. We treated 3T3-L1 adipocytes with OSM, …

Midbrain dopamine (DA) and serotonin (5-HT) neurons regulate motivated behaviors, including feeding, but less is known about how these circuits may interact. In this study, we found that DA neurons in the mouse ventral tegmental area bidirectionally regulate the activity of 5-HT neurons in the dorsal raphe nucleus (DRN), with weaker stimulation causing DRD2-dependent inhibition and overeating, while stronger stimulation causing DRD1-dependent activation and anorexia. Furthermore, in the activity-based anorexia (ABA) paradigm, which is a mouse model mimicking some clinical features of human anorexia nervosa (AN), we observed a DRD2 to DRD1 shift of DA neurotransmission on 5-HTDRN neurons, which …

Coronavirus disease 2019 (COVID-19) remains a global public health threat. Hence, more effective and specific antivirals are urgently needed. Here, COVID-19 hyperimmune globulin (COVID-HIG), a passive immunotherapy, is prepared from the plasma of healthy donors vaccinated with BBIBP-CorV (Sinopharm COVID-19 vaccine). COVID-HIG shows high-affinity binding to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein, the receptor-binding domain (RBD), the N-terminal domain of the S protein, and the nucleocapsid protein; and blocks RBD binding to human angiotensin-converting enzyme 2 (hACE2). Pseudotyped and authentic virus-based assays show that COVID-HIG displays broad-spectrum neutralization effects on a wide variety of SARS-CoV-2 variants, …

Division of Basic Science Faculty Publications

Non-resolving pancreatic islet inflammation is widely viewed as a contributor to decreases in β-cell mass and function that occur in both Type 1 and Type 2 diabetes. Therefore, strategies aimed at reducing or eliminating pathological inflammation would be useful to protect islet β-cells. Herein, we described the use of 2′,4′-dihydroxy-4-methoxydihydrochalcone (DMC2), a bioactive molecule isolated from an ethanolic extract of Artemisia dracunculus L., as a novel anti-inflammatory agent. The ethanolic extract, termed PMI 5011, reduced IL-1β-mediated NF-κB activity. DMC2 retained this ability, indicating this compound as the likely source of anti-inflammatory activity within the overall PMI 5011 extract. We further …
