Digital language archives are used for the preservation of documented language data, such as video and voice recordings, transcriptions, survey data, and ethnographic fieldnotes. This data is most often used for research and linguists and anthropologists are generally heavily involved in the creation of language archives. Ideally, Indigenous communities that are represented in the archives are also able to access their data, but this is not always the case, especially if poor internet access and lack of technological know-how prevent archive use. In addition, western epistemologies are embedded in archival logics, exacerbating the issues surrounding Indigenous access and pointing to the need for a decolonizing archival design that centers the needs of its users. Using ethnographic research methods and a decolonizing framework, I conducted a usability study on the Archive of the Indigenous Languages of Latin America (AILLA) to uncover the cultural-based meanings that inform AILLA use. Using linguistics and anthropology listservs, I recruited research participants for a Qualtrics survey and conducted semi-structured interviews that explore the user perspective on AILLA. I analyzed AILLA's Google Analytics data and used qualitative and quantitative research methods to build upon the previous literature in user-centered design approaches to language archives. As one of …

Previous literature has identified links between psychopathic trait severity and disturbed styles of attachment on sexual outcomes in adulthood. However, few studies have investigated these domains within one design. Therefore, it is unclear how they may influence each other, given that an association between attachment styles and psychopathic traits has also been previously documented. This study sought to explore the possible role of psychopathic traits upon the association between attachment and sexual outcomes. Participants were sampled from an undergraduate student population at a large university. Data were analyzed using correlational and hierarchical regression analyses, as well as two exploratory path models. Analyses suggested that aspects of attachment and psychopathic trait severity were significantly associated with each other and differentially predicted certain sexual outcomes. Furthermore, results indicated that the effects of attachment avoidance on sexual outcomes were mediated by Factor 1 traits of psychopathy, while the effects of attachment anxiety were mediated by Factor 2 traits. Additionally, it was found that attachment style was linked with contempt, and this was further linked to disturbances in sexual outcomes, which is a novel finding. Implications of the findings, limitations, and future directions are discussed.

Elevated social anxiety is a well-documented risk factor for developing problematic alcohol use behaviors. Adolescents with high social anxiety often report drinking for coping-related reasons, and drinking to cope has been linked to both acute and chronic alcohol use problems. Research further suggests that parenting is a primary socialization domain in terms of adolescent alcohol use onset and trajectory; however, no work has yet examined the role of parenting factors in the relation between social anxiety and coping motives for drinking. The current study investigated the role of two parenting dimensions, rejection/warmth and psychological control, on the link between social anxiety and problematic drinking motives. Drawing from an ongoing assessment of an inpatient program, the sample consisted of 94 girls and boys (ages 11-17 years). Regression analyses evaluated main effects of social anxiety, rejection, psychological control, the interactive effects of the parenting dimensions, and the three-way interaction of both parenting dimensions with social anxiety on coping motives for alcohol use. As expected, social anxiety was positively and statistically significantly related to coping motives when examined via raw scores, proportional values, and in the final model. Further, zero-order correlations indicated a positive, statistically significant relation between proportional coping motives and both …

Wii Fit U games utilize a Wii Balance Board™ (WBB) in a manner that can provide precise feedback contingencies similarly to some forms of balance rehabilitation, thereby potentially increasing the dose of quality therapy with or without the presence of a therapist during post-brain injury rehabilitation. Additionally, an engaging video-game could improve treatment adherence, a critical aspect of making positive functional gains, by potentially increasing the rate and quality of reinforcement embedded in therapy. The present study had three aims: (1) develop a rigorous behavioral therapy for improving balance in individuals living with chronic brain injury using a Wii Fit U game and the WBB; (2) evaluate the program's effects on balance measures using a within-subject experimental design; and (3) assess social validity of behavioral gains by evaluating the program's effects on participant's "subjective balance confidence" (i.e., their Activities-Specific Balance Confidence (ABC) scores). A reversal design is proposed for use with primary study participants, wherein the experimental gameplay condition and no intervention condition are alternated for 6 to 10 weeks. A similar design was used in a truncated fashion with pilot participants, and a multiple baseline design was used with follow-up pilot participants. It was expected that participants would exhibit …

This thesis focuses on tribal engagement and tribal consultation in the United States. In the thesis, I discuss my experience working on an interdisciplinary research team completing a formal ethnographic study which was submitted to a federal agency. Using insights gained from this experience and additional experience working with American Indian tribes, I discuss historic, contemporary, and potential future strategies for involving and engaging American Indian tribes in land and resource stewardship decisions in the United States.

From 2011 to 2014, one of the most severe and intense droughts in Texas recorded history led to widespread wildfires across the state, with unknown effects on atmospheric nutrient and pollutant deposition. The objectives of this research were to: (1) characterize the frequency, magnitude, and spatiotemporal distribution of Texas wildfires (2011-2014); (2) identify smoke occurrence and source regions at eight Texas National Atmospheric Deposition Program (NADP) National Trends Network (NTN) sites (2011); and (3) quantify the influence of wildfire on weekly rainwater chemistry and deposition in 2011 at three NADP sites (Sonora, LBJ Grasslands, Attwater Prairie NWR). Data on large wildfires, smoke occurrence, and rainfall chemistry and deposition were coupled with principal component and back-trajectory analysis to address these objectives. Between 2011-2014, 72% of all wildfires occurred in 2011, accounting for 90% of the total area burned. In total, there were 17 extreme wildfires (i.e., in the 95th percentile of hectares burned), of which 11 occurred in 2011. Wildfire activity was concentrated in West Texas ecoregions and consumed primarily shrub/scrub and grassland/herbaceous land cover. Although West Texas experienced the most wildfires, smoke at the NADP locations in 2011, the "high-fire year," was more frequent in East Texas due to regional …

Like many institutions of high education throughout the United States, the University of North Texas requires all students to pass introductory United States History courses. While the purpose of these courses should be to create a population well versed in U.S. history and sociopolitical and economic context, the foundational textbooks utilized in these courses promote American exceptionalism and U.S. supremacy. Their omission of the complex and controversial history of the United States creates a false master narrative based on an idealized version of U.S. history. Even textbooks that include diversity continue to uphold a progressive master narrative that ignores issues of systemic racism, sexism, and homophobia. My theoretical analysis of the required textbooks, Exploring American Histories: A Survey with Sources, is applicable to all introductory U.S. history textbooks. Decolonialism, critical race, and intersectional feminism are theoretical lenses that disentangle and highlight otherwise invisible aspects of American exceptionalism and the serious consequences of the subjugation of subaltern historical narratives. This thesis applies theory with examples of how textbooks or supplemental teaching can expose foundational oppression, violence, and discrimination to teach students critical thinking and help them see connections between the past and their present.

Climate change is a growing problem for those living in the Himalayas, threatening water availability and livelihoods. This research seeks to explore the various factors contributing to water shortage and the factors leading to perceptions of water shortage in Himachal Pradesh, India. This thesis explores data collected from 50 interviews conducted in summer 2019 and seeks to understand why participants of these interviews indicated that they do not experience water shortage. The research highlights the importance of further research and needed action in terms of addressing and mitigating the impacts of climate change in the Himalayas of Himachal Pradesh.

Youth in the United States are experiencing a steep increase in mental health issues. Concurrently, unique political, economic and social dynamics in the U.S. make the circumstances of nonwhite children's mental health partially contingent on experiences of racism. In this study, I examine the relationship between racial minority children's mental health and perceived racism, while also examining the moderating effects of gender on this relationship. I first review prior research which suggest that racism is a salient determinant of several health outcomes among racial minorities and racial minority children, including depression and anxiety. I then review research on both gender and racial socialization and posit possible implications of these differentials on mental health. Considering both the racialized and gendered factors contributing to youth's mental health outcomes, this study fills a gap in previous research by exploring the differences by gender and race in the effect of perceived racism on children's mental health. I use data from the National Survey of Children's Health from 2016 to 2019. Using average marginal effects, calculated from a series of logistic regression models predicting depression, anxiety, behavioral and emotional problems, I find support for previous research which suggests that perceived racism predicts poor mental health …

This study explored NCAA athletic departments' mental health screening practices, including the mental health concerns assessed for by the mental health screening, personnel responsible for administering and reviewing screeners, and resources available for athletes identified as "at risk." Participants were athletic department staff who had knowledge of their school's mental health screening processes. Frequencies and chi-square analyses were used to assess trends across divisional levels (DI vs. DII/DIII). Analyses show that significantly more DI than DII/DDIII institutions have a formal mental health screening program. Institutions' coverage of mental health topics in their screening did not vary significantly by Divisional level, with one exception: a larger percentage of DI institutions assessed whether student athletes had worked with a mental health practitioner than DII/DIII schools. DII/III were significantly more likely to have athletic trainers both administer and review mental health screeners and DI institutions were significantly more likely to have a sport psychologist employed within their athletic department than. DI schools were significantly more likely to have had a student athlete attempt suicide and participate in inpatient treatment than DII/III schools. Implications of the findings, limitations, and future directions are discussed.

Autism spectrum disorder (ASD) presents with difficulties in social communication, repetitive and/or restricted behaviors, as well as variable language development. Individuals with suspected ASD ideally participate in assessments which include measures of cognitive abilities, adaptive functioning, language functioning, and ASD specific measures (i.e., ADOS, ADI-R). Diagnosis of ASD can occur confidently at 2 years of age, however, the mean age at diagnosis is 4-5 years old. Delays in diagnosis are accounted for by lacking professionals and centers with the capabilities to assess ASD, as well as long waitlists for assessments. Early identification and intervention have been shown to provide the best improvements in ASD symptomology. The aim of the current study was to conduct a program evaluation of an autism treatment center that was designed to provide high quality evidence-based interventions. The study determined if treatment-as-usual in that center yields the expected gains in adaptive functioning and corresponding decreases in barriers to learning. Results indicated improvement in scores on standardized direct assessment of milestone achievement and barriers to learning, but no significant improvement in adaptive skills via secondary informant questionnaire measures following 6 months of treatment. The overall sample size was small due to COVID-19 complications, lack of institutional procedures, …

The purpose of this study was to investigate the effects of Pb and hypoxia co-exposure on Pb toxicity and Ca homeostasis in early life stage (ELS) zebrafish (Danio rerio). Previous evidence indicates that exposure of ELS zebrafish to hypoxia (~20% air saturation) reduces Ca uptake, likely through down-regulation of the apical epithelial Ca channel (ECaC). Considering that Pb and Ca are known antagonists and compete for uptake pathways, it was hypothesized that co-exposure of Pb with hypoxia would decrease Pb toxicity by reducing Pb uptake (likely mediated through a reduced number of ECaCs). However, it was shown that at 96 hpf, whole body accumulation of both Pb and Ca was lower at 40% air saturation compared to 100% and 20% air saturation. This result closely aligned with the 96h LC50 results which showed the highest mortality of zebrafish at 40% compared to the other air saturation levels. This suggests that toxicity is likely the result of exacerbated hypocalcemia at 40% air saturation due to both Pb competition for Ca binding to Ca uptake channels/transporters, such as ECaC, and potentially reduced expression of such channels/transporters in response to this level of hypoxia. Overall, it appears that ELS zebrafish respond differentially to …

Prevalence of mental health concerns among young adults is high and continues to increase. As a specific subset of young adults, NCAA student-athletes seem to experience these concerns at a similar or greater prevalence than their non-athlete, age-matched peers. Despite the number of college student-athletes who are experiencing mental health concerns, understanding how mental health impacts sport performance has not been robustly studied and has not included the diversity of identities present in the athlete population. Thus, I explored the beliefs of 266 college student-athletes who represented diverse identities and sports regarding how mental health impacts sport performance. Responses were collected using an on-line survey and analyzed using both quantitative and qualitative methods. Overall, as well as by gender, race/ethnicity, and sport type, 96.4% to 100.0% of participants believed that mental health impacts sport performance. From thematic analysis emerged three themes and various subthemes: (a) cognitive disruptions (concentration, confidence, self-talk, motivation, mindset, and decision-making), (b) the stress of being a student-athlete (life impact sport, team factors, sport impacts mental health), and (c) a mind-body connection (mind correlates with body, and mental health symptoms impact sport performance). Post-hoc cluster analysis by demographic and sport-type variables did not reveal clustering; these variables …

Multiple contributors to neurocognitive impairment in individuals with sickle cell disease have been identified. Research indicates that a history of cerebrovascular accidents, such as silent infarcts and strokes are associated with greater cognitive decline among children with sickle cell disease. Additionally, disease effects such as hemoglobin and hematocrit levels significantly effect cognitive performance among this population and should be taken into consideration when examining neurocognitive impairment. Further, previous studies show a significant relationship between child behavior problems, family functioning, and cognitive performance in children with sickle cell, marking those as important targets for intervention among this population. While cognitive decline with increased age is not typically examined in healthy child populations, some research indicates the presence of age effects in those with SCD. A majority of the literature addresses cognitive impairment from a broad perspective, while a limited number of studies have begun to address effects among specific cognitive domains. Using archival data from the National Institutes of Health's Cooperative Study of Sickle Cell Disease, results revealed that disease severity was negatively correlated with some aspects of cognitive functioning, including visual-spatial domains. Additionally, some measures of cognitive performance were inversely correlated with age. Consistent with hypothesized outcomes, family functioning was …

This research investigates particulate matter (PM) deposition to rock pigeons (Columba livia) in urban environments within Denton County, Texas. Pigeon habitat was characterized within a 2-km radius at eight locations using the 2016 National Land Cover Database (NLCD). In summer 2020, feathers were sampled from 10 rock pigeons at two locations (n = 20) differing in degree of urban development. Birds were captured using walk-in funnel traps baited with bird seed. Based on molt pattern and appearance, four old flight feathers were identified and sampled from each bird. New primary feathers were obtained from each population as reference samples. Feathers were washed three times with double deionized water and acetone, and the solution vacuum filtered through a glass microfiber filter to collect all particles >1.5 µm in diameter. Particulate matter mass was determined by gravimetric analysis and calculated per unit feather surface area. Relative PM accumulation rates were significantly different between the populations. Characteristics of urban land cover, proximity to and types of emissions sources, wind exposure, and building density were drivers of variability in PM deposition to feather surfaces. The results from this study should be useful for subsequent research to help identify best practices for using feathers collected …

West Dallas AR is an interactive location-based app, using the power of multimedia and augmented reality to highlight the stories shared by West Dallas residents.

Betrayal trauma theory (BTT) explains the relationship between a victim and perpetrator to be an especially critical factor for predicting adverse trauma outcomes; however, to date, there is no adequate measure to assess this relationship. We aimed to create a measure of reliance, here defined as dependence on another for food, clothing, finances, emotional support, and more. We utilized a new scale, the Reliance on Perpetrator Scale, to measure this construct. 397 participants completed a battery of questionnaires to measure reliance and 4 primary outcomes of interpersonal trauma exposure: PTSD symptoms, depression, event centrality, and dissociation. A series of exploratory principal components factor analyses provided evidence for a 3 factor solution for this scale, though visual examinations of scree plots and a parallel analysis indicated 2 factors. We ultimately chose to retain 2 factors: practical reliance and emotional dependence. We expected and achieved predictive validity such that practical reliance and emotional dependence were both highly positively correlated with all outcomes. We expected and achieved convergent validity such that positive affect and secure attachment were highly positively correlated with emotional dependence as measured by an existing scale. The current study replicated previous findings that high betrayal events—as opposed to low betrayal …

Members of the elderly population is disproportionately prone to experiencing mobility impairment due to their aging bodies and as a result have frail bodies that are at a higher risk of grave injury due to falling. In order to combat this assistive mobility devices such as exoskeletons have been developed to help patients enhance their range of motion. With additive manufacturing techniques, such as fused deposition modeling (FDM), becoming a more mainstream form of design, the inclusion of lightweight polymers such as nylon 12 as primary construction materials for these devices has increased. In this thesis computer aided design (CAD) software was used to design a prototype lower body exoskeleton and simulation software was used to give the device the characteristics of Stratasys' nylon 12 carbon fiber FDM material to verify it if could be used as the primary construction material for this device when extruded from a FDM printer on either the XZ or ZX printing plane. From the simulations it was found that the material printed along the XZ plane could create a device that could withstand the weight of an average elderly male patient (200 lbs.) as well as the 35 lbs. of force applied to the …

In this thesis, I explore the careers and songs of Florence Price and Margaret Bonds—two African American female composers who were part of the Chicago Renaissance. Price and Bonds were members of extensive, often informal, networks of Black women that fostered creativity and forged paths to success for Black female musicians during this era. Building on the work of Black feminist scholar Patricia Hill Collins, I contend that these efforts reflect Black feminist principles of Black women working together to create supportive environments, uplift one another, and foster resistance. I further argue that Black women's agency enabled the careers of Price and Bonds and that elements of Black feminism are not only present in their professional relationships, but also in their songs. Initially, I discuss how the background of the Harlem and Chicago Renaissances and racial uplift ideology shaped these women's artistic environment. I then examine how Bonds and Price incorporated, updated, and expanded versions of these ideals in their music and careers. Drawing on the scholarship of Rae Linda Brown, Angela Davis, and Tammy L. Kernodle, I analyze Price's "Song to the Dark Virgin," "Sympathy," and "Don't You Tell Me No" and Bonds's "Dream Variation," "Note on Commercial Theater," …

The minority stress model provides context to understand the mechanisms by which prejudicial experiences contribute to the disproportionate prevalence of adverse physical and mental health outcomes among LGBT people. The transactional model of stress and coping explains the appraisal processes through which people identify stigma-related stimuli as threatening and how they assess available coping resources to counteract these threats. The Connor-Davidson Resilience Scale (CD-RISC) and the Perceived Stress Scale (PSS) were used in this study to measure resilience and stress in a sample of 99 lesbian and gay older adults. Women reported statistically significantly higher levels of resilience and lower levels of perceived stress compared to older gay men. An analysis of covariance (ANCOVA) revealed statistically significant main effects for gender (Cohen's d = .51; ηp2 = .056; F(1,98) = 5.488, p = .021) while controlling for perceived stress (Cohen's d = 1.62; ηp2 = .375; F(1,98) = 55.840, p < .001). An interaction effect between gender and perceived stress was also statistically significant (Cohen's d = .72; ηp2 = .115; F(1,98) = 12.40, p < .001) indicating that the negative relationship between stress and resilience is stronger for older gay men. Clinical implications and relevance to future research are …

Low-cost sensors have the potential to create dense air monitoring networks that help enhance our understanding of pollution exposure and variability at the individual and neighborhood-level; however, sensors can be easily influenced by environmental conditions, resulting in performance inconsistencies across monitoring settings. During summer 2020, 20 low-cost particulate sensors were deployed with a reference PM2.5 monitor in Denton, Texas in preparation for calibration. However, from mid to late-summer, dust transported by the Saharan Air Layer moved through the North Texas region periodically, influencing the typical monitoring pattern exhibited between low-cost sensors and reference instruments. Traditional modeling strategies were adapted to develop a new approach to calibrating low-cost particulate sensors. In this study, data collected by sensors was split according to a novel dust filter into dust and non-dust subsets prior to modeling. This approach was compared with building a single model from the data, as is typically done in other studies. Random forest and multiple linear regression algorithms were used to train models for both strategies. The best performing split-model strategy, the multiple linear regression models split according to dust and non-dust subsets (combined R2 = 0.65), outperformed the best performing single-model strategy, a random forest model (R2 = 0.49). …

To what extent does Margaret Atwood draw from American slavery to write The Handmaid's Tale? How does Offred's narrative compare with traditional slave narratives, and to what effect? This thesis explores intersectionality (or lack thereof) in The Handmaid's Tale and compares Offred's narrative to traditional slave narratives to find answers to why Atwood chose to draw from American slavery to write her novel in the first place. Offred's narrative is compared to three traditional slave narratives written/orated by three women, Harriet Jacobs, Hannah Crafts, and Mary Prince, to demonstrate how enslavement dehumanizes Offred in similar or different ways to these three women, and to reveal how the enslavement of and violence committed against the female slave body ultimately deforms even the most intimate human relationships in both Gilead and in historical American slavery. I discuss other tactics used to maintain control of the slaves both in Gilead and in historical American slavery, with particular emphasis on the development of justifications for enslavement in both societies. Violence against the body is not enough in Gilead, so Gilead implements religious rhetoric and controls knowledge to maintain its control of the Handmaids. Despite being used to control, religion also becomes a source of …

Anthropology is an underrepresented subject in precollegiate education. Despite concerted institutional efforts through organizations such as the American Anthropological Association (AAA), there has not been significant growth in the field. Although the field of anthropology has not shown significant growth at the precollegiate level, there does exist a presence of precollegiate anthropology, especially through the International Baccalaureate Organization (IBO) and standalone courses at schools at the elementary through high school level. Many of these standalone courses were created by an individual teacher. This applied thesis used anthropological methods to identify if a social network exists among precollegiate anthropology teachers while also examining how the AAA can create and/or facilitate a stronger community of precollegiate anthropology teachers. Linking to institutions such as the Advanced Placement program in addition to IB may create the critical mass to encourage a positive feedback loop which produces more anthropology students at the college level and more individuals who create standalone courses. With a growth in precollegiate programs, the existing social networks within and outside the AAA will grow.

This thesis is a critical analysis and creative commentary providing research and insight into my 150-minute multimedia exhibition, "Femininity: Ownership and Power," that premiered October 23, 2021. All of my research, composition, and collaboration efforts seek to recontextualize the semiotics of ‘femininity' through ownership and empowerment from varying intersections and identities. The titles of the eight works composed and premiered as part of the exhibition include: a beautiful reckoning; Dust; Moirai; Gaia; Portrait of the American Woman; Shared, In Balanced Contrast; At My Intersection; and I See You. Also included was #pinkcode, an exhibit that features a fuschia graphic user interface for an interactive modulation synthesis application built in Csound designed to bring femininity into computer music spaces. The musical compositions vary in instrumentation including flute, alto flute, voice, guitar, viola, harp, cajon, vibraphone, live electronics, and fixed media. They also vary in medium including live performance, virtual reality video, music video, audio-reactive TouchDesigner video, immersive text projections, light show, and live dance.
