Victims of racial discrimination often experience negative consequences that extend into all aspects of well-being (e.g., psychological, subjective, social). Racial microaggressions describe a series of verbal and non-verbal behaviors that cause harm, perpetuate negative stereotypes, and negate the experience of racial/ethnic minorities. Research has found a negative relationship between experiencing racial discrimination and psychological well-being, as well as a potential buffering effect of racial/ethnic identity. However, less information is available about the existence of these relationships with social well-being. The purpose of this dissertation is to fill a gap in the literature in regard to racial microaggressions, racial/ethnic identity, and social well-being in 453 racially diverse undergraduate students. Quantitative results indicated that African Americans reported higher levels of racial microaggressions and racial/ethnic identity than other groups, racial microaggressions were negatively associated with sense of belonging, racial/ethnic identity was positively associated with sense of belonging, and the association between racial microaggressions and sense of belonging was not moderated by racial/ethnic identity. Qualitative analyses using the conventional content analysis revealed two clusters of facilitative behavioral expressions of university/community inclusion: (a) interpersonal expressions of inclusion and (b) systemic expression of inclusion. I conclude by discussing limitations, areas for future research, and implications for …

The current dissertation had three primary objectives, categorized into two MTurk studies with capital juror-eligible community members: (a) cross-validate the psychometric properties of the JQVV, (b): explore the role of legal attitudes via the JQVV in mock capital sentencing decisions, and (c): examine the JQVV's ability to detect juror social desirability in capital voir dire. Impressively, Study 1 (N = 552) and Study 2 (N = 313) provided strong and consistent evidence for the JQVV's reliability and construct validity. In the mock juror paradigm, punitive legal attitudes on the JQVV (i.e., Crime-Neg, Convict, and Death-Pos), did not directly affect sentencing decisions, however they indirectly influenced the perception of nearly all other legally relevant variables (e.g., evidence type). For example, participants with more punitive criminal justice attitudes evaluated aggravating evidence more favorably which, in turn, increased death sentence verdicts. Study 1 also underscored the concerningly low levels of comprehension jurors have regarding judicial instructions and other relevant legal knowledge (e.g., the definition of aggravating). In Study 2, the support-life and support-death groups evidenced divergent patterns of social desirability, although support-death participants did not dramatically alter their scores between the genuine and social desirability condition. Additionally, the JQVV Pros-Cyn and Justice-Pos scales …

Using a multimethod-multimodal approach, this study compared the contributions of executive function (EF) abilities (Go No-Go, Visual Search, 2-Back task, and Task Switching) to narrative comprehension tasks (False Belief, Strange Stories, Self-Reported Theory of Mind Inventory [TOMI-SR]) and a narrative production task (interpersonal decentering) in a sample of young adults. Separate regression models were conducted for each theory of mind (ToM) measure with EF measures as predictor variables and empirically selected demographic variables controlled. As expected, in this college student sample (N = 110), False Belief demonstrated a ceiling effect and was not associated with any EF ability. Task Switching and 2-Back accounted for significant variance in Strange Stories. No EF task significantly predicted performance on TOMI-SR or interpersonal decentering. Both story comprehension tasks (False Belief and Strange Stories) were significantly associated, but these tasks were not correlated with either self-reported ToM or interpersonal decentering. Several unanticipated demographic associations were found; having more siblings and English proficiency accounted for significant variability in Strange Stories; education, presence or absence of self-disclosed autism diagnosis and mental health diagnosis explained a large portion of variance in TOMI-SR; interpersonal decentering maturity differed significantly between cisgender men and cisgender women. Lastly, interpersonal decentering number of …

Report summarizing the recommendations of The Naming Commission's findings regarding army bases as mandated by the National Defense Authorization Act for Fiscal Year 2021, which mandates the removal of names, symbols, displays, monuments and paraphernalia that honor or commemorate the Confederate States of America. "Part 1 of the three-part Naming Commission Final Report .... recommends new names for nine military bases (Fort Hood, Texas; Fort Bragg, North Carolina; Fort Rucker, Alabama; Fort Polk, Louisiana; Fort Benning and Fort Gordon in Georgia; and Fort A. P. Hill, Fort Lee and Fort Pickett in Virginia), the disposition of all Confederacy-affiliated and named Department of Defense assets on those bases, and additional guidance for the nine bases."

While some individuals experience their work as meaningful, others, with the same job, do not. The purpose of this dissertation is to answer the following question: Why do different individuals, with the same job, view the meaningfulness of their work in conflicting ways? I draw on terror management theory and generativity theory to answer this question by testing the relationship between death awareness and meaningful work. The bulk of academic work concerning meaningful work focuses on its outcomes and few scholars have explained the antecedents of meaningful work. This study aims to extend empirical work of the relationship between death awareness and meaningful.

Middle childhood is the least understood developmental period in the attachment literature, likely due to active reorganization of the attachment system during this stage. Coinciding with increased cognitive and socioemotional competencies, middle childhood attachment begins to transition from relationship-specific attachment to general attachment representations. While parents continue serving as the primary attachment figure used as a secure base and safe haven, noticeable shifts occur in terms of the need for availability over proximity to attachment figures and the child's involvement in maintaining the attachment relationship. Currently, there is no dominant conceptual or methodological approach for studying attachment in middle childhood. The present study sought to develop and validate an observational coding system examining middle childhood attachment using a dimensional approach. The Middle Childhood Behavioral Attachment Dimensions (MCBAD) system demonstrated mixed reliability and validity compared to other established attachment measures. Compared to traditional categorical attachment measures, this study provides evidence for the utility of an anxiety-avoidance dimensional attachment scale in childhood. Additionally, the MCBAD is the first observational system that examines both nonverbal and verbal attachment behaviors in an unstructured separation-reunion episode, and findings suggest a need for further examination of verbal attachment during this developmental stage.

This study examines the background and qualifications of plaintiff and defense experts using the H-Index score as quantification of expert background and qualifications. The goal is to better understand the similarities and differences among the professionals offering paid expert witness testimony in mild traumatic brain injury (mTBI) civil litigation. In this quantitative study, descriptive statistics include the mean and standard deviation scores for the data to support examining measures of central tendency and variance, respectively. The study includes the use of logistic regression and the Wilcoxon signed-rank test, and their statistical assumptions were tested to determine whether they would be used or if it was more appropriate to use a non-parametric test. The study included two research questions: How do the qualifications of plaintiff and defense expert witnesses in mild traumatic brain injury civil litigation compare? and to what extent does a higher h-index correlate with a favorable litigation outcome in a mild traumatic brain injury case? The findings for the hypothesis tests associated with the research questions led to the acceptance of the null hypothesis in each test. There was a lack of asymptotic significance in Hypothesis 1 and a lack of significance in Hypothesis 2. The findings from …

This dissertation includes background on influences of mathematics, mathematics education, and who is viewed as a mathematician leading into three articles exploring students' and teachers' perceptions of mathematics through their lived experiences in both mathematics classrooms and their communities. Using interpretative phenomenological analysis for the methodology, all three articles analyze mathematics autobiographies and semi-structured interviews with five student participants enrolled in the same Algebra I course; Paper 3 also includes the Algebra I teacher. Paper 1 focuses on how students describe their lived experiences in mathematics classrooms. Three themes emerged from the participant data: 1) lack of autonomy and access, 2) feelings hinge on performance in mathematics, and 3) the need for support in mathematics. Each participant shared different experiences, but these experiences can help inform educators how to improve students' experiences in the classroom. Paper 2 sought to understand how middle grade students make sense of what it means to do mathematics in their community. The three themes include: 1) navigating the usefulness of mathematics outside of school, 2) who directs mathematics outside of school, and 3) the need for mathematics in future plans. Connections students made between mathematics and the lives outside of school varied suggesting how broad …

Article presents a case study of a 35 year-old Caucasian woman who experienced multiple vertebral fractures two months after her second pregnancy. The results suggest a potential role of heterozygous WNT1 variants in the pathogenesis of early-onset osteoporosis. The authors suggest that teriparatide is one of the most appropriate available therapies for such cases.

Location-based ads are defined as any ads that are sent by an identified source to consumers' mobile devices when they are around the advertised product/store. Although mobile ad spending is said to have accounted for 68% of all digital ad spending in 2020, knowledge of how businesses can use mobile and location-based technology to reach their customers effectively is limited. Thus, the purpose of this three-essay format dissertation is to review the literature on LBA and identify the gaps in the literature and attempt to address a few of these gaps in the remaining two essays. The second essay tests an integrated model by examining the effects of the various retailer and consumer-controlled factors on two retail performances. In the third essay, we explore how LBA affects different dimensions of consumer-brand engagement. The results and findings provide important implications for retailers and brands to increase their performances.

Overall my dissertation work tries to capture a holistic view of the various complex interactions that occur in technology development, implementation, adoption and diffusion, in the context of three industries by examining issues that arise due to regulation of technology. Essay 1 focuses on the social media industry, which is in the early stage of the industrial life cycle, and is the foci of government attention for its ill effect on society. Results from the study (N= 647 employed adults in the US) supported hypotheses related to the antecedents and outcomes of platform utilization in the context of the three regulation dimensions. Essay 2 focuses on the automotive industry, which is in the growth stage of the industrial life cycle. Here the focus is on electric vehicles (EV) transitioning from the niches to the main market. Results from the longitudinal study (N = 429) support the moderating role of political activism on innovation capability of manufacturers and presence of ancillary services in the diffusion of different types of electric vehicles in the US market. Essay 3 focuses on the US healthcare industry, reflecting mature stage of industrial life cycle, yet also characterized with high cost and fragmentation of service. The …

Oil spills are well-known adverse anthropogenic events, as they can induce severe impacts on the environment and negative economic consequences. Still, much remains to be learned regarding the effects of crude oil exposure to aquatic organisms. The objectives of this dissertation were to fill some of those knowledge gaps by examining the effects of Deepwater Horizon (DWH) crude oil exposure on teleost kidney development and function. To this end, I analyzed how these effects translate into potential osmoregulatory impairments and investigated the interactive effects of ubiquitous natural factors, such as dissolved organic carbon (DOC) and ultraviolet (UV) light, on acute crude oil toxicity. Results demonstrated that acute early life stage (ELS) crude oil exposure induces developmental defects to the primordial kidney in teleost fish (i.e., the pronephros) as evident by alterations in: (1) transcriptional responses of key genes involved in pronephros development and function and (2) alterations in pronephros morphology. Crude oil-exposed zebrafish (Danio rerio) larvae presented defective pronephric function characterized by reduced renal clearance capacity and altered filtration selectivity, factors that likely contributed to the formation of edema. Latent osmoregulatory implications of crude oil exposure during ELS were observed in red drum (Sciaenops ocellatus) larvae, which manifested reduced survival …

Since the creation of the first all-state vocal jazz ensemble in 1978, similar ensembles have been established in roughly half of the United States. This paper contains historical summaries of the creation of all-state vocal jazz ensembles in nineteen of those states, primarily as recounted via interviews with those ensembles' founders. Each semi-structured interview was conducted over video conference or phone and lasted approximately one hour; resulting interview data was analyzed using qualitative methods. During the creation of each ensemble the respective founders needed to secure the support of a host organization, determine where and when to convene, and decide how to address auditions, sound reinforcement, rhythm sections, and funding. The diversity of solutions to these shared challenges reflects the diverse priorities of each founder as well as the unique conditions in which each all-state vocal jazz ensemble was established. However, several elements were common across these stories, including the influence of existing festivals and all-state ensembles, and tensions within the choral education community regarding the value of the vocal jazz idiom relative to traditional choirs, show choirs, and other vocal ensembles. In a few cases, established all-state vocal jazz ensembles were discontinued; these stories further illustrate the challenges such …

Teacher preparation programs are varied in their approach to preparing teachers for the realities of the classroom, particularly when working with special population students. School districts and leaders utilize mentoring and professional development opportunities to help teachers bridge the knowledge and skills gap between what they learned in their preparation programs and what they need to know in their current position for instructing special population students. The purpose of this qualitative study was to provide K-12 general education teachers an opportunity to voice their perceptions about how they were prepared to instruct special population students and what they need for increasing their level of confidence when teaching special population students. Thirteen participants were chosen for a semi-structured interview and four were chosen for a focus group. To identify future initiatives general education teachers hope their education leaders will incorporate, data were collected through stories pertaining to the successes and challenges general education teachers face when instructing special population students. Findings showed that general education teachers are overwhelmed with the increase in special population students in their classrooms and are lacking the time to fully differentiate instruction. Teachers expressed a need for training about mental illness awareness due to the number …

Despite their many successes, Roman leaders continually struggled with indiscipline in their own ranks as they battled Rome's opponents. Desertion and defection were steps that soldiers often undertook to avoid their obligated service. Previous scholarship has largely overlooked this aspect of Roman warfare. This dissertation analyzes why Roman soldiers began turning to desertion and defection throughout the Republican period. Such cases were generally rare in early Rome, but the expanding responsibilities and hardships of warfare in the Middle Republic caused them to rise, as did the sizeable growth of the Roman community. The civil wars of the Late Republic saw especially high cases of such acts, as generals incentivized defections in their opponents ranks. Roman desertion was not unique, but a common occurrence in ancient warfare. This dissertation also addresses how Romans capitalized on desertion and defection in warfare. The Second Punic War offers an example of how Rome achieved victory by encouraging defection in its enemy's alliances. Romans also relied heavily on defectors as a source of intelligence and as a tool in siege warfare. The moral forces of commitment, discipline, dissatisfaction, and desertion were often as important as the tactics and technologies of the participants in Rome's wars.

The estuarine sheepshead minnow (Cyprinodon variegatus) is the most eurythermic fish species, with a thermal tolerance window between 0.6°C and 45.1°C. However, little is known about the physiological mechanisms that allow this species to survive this temperature range. In order to understand how sheepshead minnow physiology is affected by temperature acclimation and acute changes in temperature, I conducted research on this species using a multi-level approach. I began at the organismal level, and examined the effects of these temperature changes on the sheepshead minnow's metabolic rate and swimming performance. The next chapter investigated the effects of changing temperatures on cardiac function (i.e., tissue/organ specific effects). In the final chapter, I conducted research at the sub-cellular level, and determined how mitochondrial bioenergetics / function is impacted by changing temperatures. This research shows that while sheepshead minnows are able to sustain heart function and mitochondrial respiration over a broad range of temperatures; they also display a plastic temperature response which is associated with the downregulation of standard metabolic rate and cardiac remodeling to maintain force generation. Collectively, these physiological responses may contribute to the sheepshead minnow's ability to maintain physiological and organismal function across a large temperature range.

This study focuses on the discourse that orders and creates a logic of the extraterrestrial during postmodernity, what I term "Fringe." Using Foucault's notion of discourse, I define and theorize Fringe and its formation during postmodernity, looking at the particular features of the historical moment post-1960 that contributed to the creation and regulation of a particular extraterrestrial. I then investigate historical conceptions of the extraterrestrial from Aquinas to Kant. This genealogy of the extraterrestrial reveals a rich history of the extraterrestrial and compares this history with Fringe. After this I discuss two precursors of Fringe discourse: the Society for Psychical Research and the writings of anomalous researcher Charles Fort. This investigation of pre-Fringe notions of the psychical in discourse shows how the SPR and Fort's work both created new ways of looking at and speaking about phenomena falling outside the purview of "normal science" and contributed to the formation of Fringe while also being distinguishable from it. Finally, I analyze two popular iterations of Fringe discourse—the ancient aliens hypothesis and the abduction narrative—as popularized in the works of Erich von Däniken and Whitley Strieber.

This dissertation is a collection of papers on anomalous phenomena in physics, biology, and sociology. These phenomena are primarily analyzed in terms of their temporal and spatiotemporal statistical properties. The analysis is based on both numerical simulations and, in some cases, real-world physiological and sociological data. The primary methods of analysis are diffusion entropy analysis, power spectral analysis, multifractal analysis, and survival (or waiting-time) analysis.
