Multi-Omic Assessment Shows Dysregulation Of Pulmonary And Systemic Immunity To E-Cigarette Exposure, David P. Scieszka, Devon Garland, Russell Hunter, Guy Herbert, Selita Lucas, Yan Jin, Haiwei Gu, Matthew J. Campen, Judy L. Cannon

Pathology Research and Scholarship

Electronic cigarette (Ecig) use has become more common, gaining increasing acceptance as a safer alternative to tobacco smoking. However, the 2019 outbreak of Ecig and Vaping-Associated Lung Injury (EVALI) alerted the community to the potential for incorporation of deleterious ingredients such as vitamin E acetate into products without adequate safety testing. Understanding Ecig induced molecular changes in the lung and systemically can provide a path to safety assessment and protect consumers from unsafe formulations. While vitamin E acetate has been largely removed from commercial and illicit products, many Ecig products contain additives that remain largely uncharacterized. In this study, we …

Human Diversity In Molecular Sexual Dimorphism And Gender Disparities In Health, Adam Z. Reynolds

Anthropology ETDs

Although males and females exhibit an extraordinary range of diversity in sexual dimorphism across populations, prior work on the evolution of sexual dimorphism in human physiology and health has focused on ostensibly universal differences that owe to sex chromosomes and steroid hormones. This dissertation argues that sexual dimorphism in humans is not adequately captured by species-wide sex differences in mean trait values, but instead varies greatly as a result of: (i) our ability to adapt physiologically to a broad range of social and physical environments, and (ii) molecular diversity acquired by different populations over the course of their unique evolutionary …

Reinforcement Learning-Based Resilience And Decision Making In Cyber-Physical Systems, Fisayo Sangoleye

Electrical and Computer Engineering ETDs

Cyber-physical systems (CPS) transform how humans interact with technology by integrating sensing, computation, networking, and control with physical processes to facilitate smart services and innovative applications in our environments. Recent advances in CPS have led to rapid growth in the amount of information constantly generated by people, systems, and processes. Most of this information, however, is underutilized due to the lack of efficient information utilization and decision-making techniques. Also, the increasing interconnectivity of CPSs presents security risks that, if left unaddressed, could be highly disruptive to systems, processes, and economies. In this dissertation, we present a study and proposal of …

Implementing Ethics Education For Nurse Managers, Mona L. Lateyice, Rachel E. Marzec

Doctor of Nursing Practice Scholarly Projects

Background: Every day, nurses are faced with making decisions for patient care and may come across complicated ethical decisions. Ethical practice is essential in every health care organization in providing care and how they conduct themselves (ANA, 2015). Nurse managers are responsible for ensuring ethical standards are met by nursing staff.

Problem: Nurse managers are faced with ethical problems more than fifty percent of their work time (Aitamaa, 2019). There are studies that show nurse managers and nurses have difficulty solving ethical problems because they lack understanding of ethical principles (Huang, et al., 2020). Evidence shows nurses are deficient in …

Pragmatic Elements In Efl Learners’ Request E-Mails To Teachers: A Study Of Learners’ Communicative Success, Hamzah Ahmad A. Kuriri

Language, Literacy, and Sociocultural Studies ETDs

Language is a tool for communication. People use it when they converse with each other. One way to comprehend what is being said is based on understating the intended meanings of the conversation, or what is called the underlined meanings (pragmatics). Pragmatic studies how different meanings are conveyed, depending on the utterances provided. A case study to investigate the phenomenon of pragmatics is selected as the methodology to specifically examine English as a foreign language (EFL) instructors’ perceptions of EFL students’ e-mails sent to their instructors. Qualitative methods are used to examine data for a period of almost three months …

It Is What It Is... Enduring The Never-Ending: The Lived Experiences Of Parenting Adult Children With Developmental/Intellectual Disabilities, Siri Gurunam Kaur Khalsa

Nursing ETDs

The parental home is the principal place of residence for adults with developmental disabilities/ intellectual disabilities (DD/ID) (Heller et al., 2007). More than 75% of the adult population with DD/ID living in the U.S. continue to have their basic needs provided by their parents (Williamson & Perkins, 2014). This is based on the estimated statistic that 1.0 to 1.58% of the U.S. adult population has a developmental disability (Anderson et al., 2019; Fox et al., 2015). About 2.9 million adults with DD/ID live with a parent of 55 years (Byun et al., 2006), with more than 25% of these parents …

Four participants completed DA sessions across three instructional conditions: (a) requesting actions embedded in play, (b) labeling actions embedded in play, and (c) labeling actions presented via video. Performance across these conditions along with a control condition was compared using an adapted multielement single-case design. Three participants demonstrated learning in at least two instructional conditions, and only one showed progress in the control condition. Overall, participants initially required less cueing to …

The Affective Landscapes Of Herbalism In New Mexico, Samantha Angelou Stroud

Geography ETDs

Herbalism, or practices which use plants for medicinal purposes, is tied to traditions in several cultures of the American Southwest, including Indigenous herbal medicine, Mexican-American curanderismo, and Western herbal traditions. Herbalism has been steadily gaining mainstream popularity since the late 1960s, alongside counterculture, holistic health, and back-to-nature movements, introducing many newcomers to the practice. This study asks: How does herbalism create and attach meaning to plants, cultures, and place in New Mexico? What are the affective landscapes produced by herbalism in New Mexico? And, to what extent do meaningful attachments manifest in ethics and actions of care? I argue that …

Impact Of Emotional Processing On Working Memory In Preadolescents With High Autistic And Anxiety Traits, Teagan Mullins

Psychology ETDs

Adolescence is an important neurodevelopmental period that confers both opportunity for positive change, and a risk for emerging psychopathology. In particular, anxiety disorders and autism spectrum disorder (ASD) both cause significant challenges during adolescence that impact individuals throughout their lifespan. Notably, functional impacts of anxiety and ASD are not limited to those who meet diagnostic criteria, and can be present at sub-clinical levels. However, despite high rates of co-morbidity of ASD and anxiety symptomology, the degree to which the neural bases of anxiety are similar or qualitatively different in individuals with and without autistic traits is unknown. One candidate neurobehavioral …

The Effect Of Shrub Cover On Conifer Water-Use Patterns, Growth, And Response To Climate Change In The Southern Sierra Nevada, Marissa Goodwin

Biology ETDs

As wildfires increase in size and severity, large areas of forest are undergoing substantial increases in shrub cover. In forests where water is the limiting resource, the partitioning of soil water between shrubs and trees may determine how shrubs affect tree growth and water-stress. We analyzed the δ²H and δ¹⁸O values of xylem water for two conifer species (Abies concolor and Pinus jeffreyi) and two shrub species (Arctostaphylos patula and Ceanothus cordulatus) to assess how shrub cover affects the water-uptake patterns of conifers in the southern Sierra Nevada. We found that growing …

Neuroinflammatory And Metabolomic Temporal Dynamics From Inhaled Wildfire Smoke With Attenuation Via Pharmacological Intervention, David Scieszka

Biomedical Sciences ETDs

Wildfire smoke is a global issue affecting nearly all humans on the surface of this Earth. Smoke dispersion from wildfires can span continents and cross oceans with amazing ease. Furthermore, total acres of land burned per year in the United States has roughly doubled since 1980, meaning this issue will persist for an indeterminate amount of time. Exposure to wildfire smoke is hazardous and promotes aging-associated events in the cardiopulmonary systems. Yet long- and short-term effects on the brain remain relatively unknown. From these, it is critically important to understand the neurological impacts from wildfire smoke exposure; to compare these …

The “Afro In Afrolatinidad”: Examining Afrolatinx Experiences Of Blackness Through And Afrolatin Critical Theory Of Race, Celine Maria Ayala Ph.D

Sociology ETDs

Scholars of Afrolatinidad across disciplines often use their work to highlight the diversity of the Latinx community (Cahuas, 2019). Those who highlight Blackness in Latinidad tend to do so by merging Chicanx, and other Latinx theories with theories of Blackness that are centered on African American experiences. Although important, these works only tell one side of a multivariant story. Using a critical, diasporic, intersectional theoretical approach, which I call an Afrolatin Critical Theory of Race (ACTR), along with 30 semi-structured in-depth interviews, I find that Afrolatinx folk navigate Blackness, educational attainment and language in ways that debunk the myth of …

The Gayborhood Was Never Here For Some Of Us! Health Consequences Of Racialized Exclusion Among U.S. Sexual Minorities Across The Lifecourse, Kasim Ortiz

Sociology ETDs

Sexual minorities exhibit elevated rates of cigarette smoking, although disparate patterns exist when examining racial/ethnic differences among sexual minorities in the United States. Evidence suggests examining differing neighborhood contexts may help illuminate drivers of tobacco-related outcomes among sexual minorities, especially with respect to racial/ethnic variations among this understudied population. Adapting a framework of whiteness and health, the current project examined the role of racial residential segregation and neighborhood disadvantage as neighborhood contexts significantly associated with cigarette smoking across the adult lifespan. Using data from the 2010 Social Justice Sexual Project, merged with U.S. Census data, I find that residing in …

Strength As A Function Of Liquid Water Content In Different Snow Types - Results From Field Experiments Using A Blade Hardness Gauge, Mikael Schlumpf

Civil Engineering ETDs

The rapid weakening of snow layers that locally accumulate infiltrating liquid water is a well-known mechanism for wet slab avalanche formation. To quantify this process and improve the prediction of these destructive avalanches, a blade hardness gauge (BHG, a.k.a thin blade penetrometer) and SLF snow sensor were used to take 349 targeted paired measurements of strength and LWC, respectively, in the snow above 19 artificially wetted capillary barriers. Using a multiple regression analysis, we develop an expression for the blade hardness of manually wetted snow as a function of LWC, crystal form, and blade hardness prior to wetting. To understand …

Modeling And Characterization Of Cmos Logic Gates Under Large Signal Rf Injection, Zahra Abedi

Electrical and Computer Engineering ETDs

This research addresses the issue of electromagnetic interference (EMI) in digital electronics, which can cause undesired behavior in active electronic components and systems. As technology advances and transistor size decreases, devices become more susceptible to EMI. In addition, as voltage is scaled down to save energy, silicon chips become more susceptible to soft errors. While there are several ways to mitigate the impact of severe EMI on digital systems, minimal electromagnetic coupling can still cause significant problems. We develop analytical models to predict device upset due to EMI. The study focuses on identifying vulnerable parameters of operation related to device …

School Voices: An Exploration Of Early Career Teachers’ Narratives On Student Voice And Dialogic Practices, Rachel Ada Meiklejohn

Language, Literacy, and Sociocultural Studies ETDs

Classrooms are typically organized around the expectation that students’ voices should be used primarily for reciting answers elicited by teachers. Numerous studies show that moving away from this recitation model towards more dialogic practices has the potential to make literacy learning more effective and inclusive. Yet, dialogic classrooms in which students’ voices work together to create knowledge and make meaning of texts remain rare, especially in classrooms serving students of low-income and minority backgrounds. In order to understand how teachers develop their thinking about student voice and dialogic practices in literacy learning, I completed a qualitative case study of ten …
