The Revised Stress-Related Growth Scale: Improving the Measurement of Posttraumatic Growth
Authors:   , Bedford Lee
Published: February 2025

This study evaluated a revised version of the Stress-Related Growth Scale (SRGS-R). The SRGS-R has two major differences from the Stress-Related Growth Scale (SRGS). It uses neutral wording of items instead of the original positively worded items, and it uses positive and negative scaling choices. This study included participants (N = 764) recruited through Amazon MTurk. There were three versions of the SRGS-R tested - the SRGS with neutral wording of items only (SRGS-R-N), the SRGS with positive and negative scaling only (SRGS-R-S), and the SRGS-R, with both changes. We randomly assigned participants to complete one of four PTG measures - the SRGS-R-N, SRGS-R-S, SRGS-R, or the Posttraumatic Growth Inventory (PTGI). The PTGI elicited the largest levels of reported PTG, while the SRGS-R elicited the smallest levels. The two modified versions displayed scores between the SRGS-R and the PTGI in the small and moderate growth groups. In the current study the SRGS-R was negatively related to PTSD symptoms, depression, anxiety (negative, but not statistically significant), global distress (negative, but not statistically significant), and avoidance-focused coping (negative, but not statistically significant), and positively related to positive well-being, quality of life, problem-focused coping, and emotion-focused coping. In comparison, the PTGI was unrelated to depression, anxiety, and global distress, and positively related to PTSD symptoms, positive well-being, quality of life, and all three coping styles. These findings provide further evidence that the SRGS-R is an improvement over the PTGI in measuring actual growth, while limiting illusory growth. We found the combination of these changes yields the greatest improvements in measurement. By improving the measurement of PTG, we can reduce the variation in reported PTG following traumatic events found throughout the literature. This will allow researchers and clinicians to better identify which factors contribute to growth following traumatic events, and aid them in designing treatments to encourage actual growth following traumas.
Computational Simulations of Cancer and Disease-Related Enzymatic Systems Using Molecular Dynamics and Combined Quantum Methods
Authors:   , Walker Alice Rachel
Published: February 2025

This work discusses applications of computational simulations to enzymatic systems with a particular focus on the effects of various small perturbations on cancer and disease-related systems. First, we cover the development of carbohydrate-based PET imaging ligands for Galectin-3, which is a protein overexpressed in pancreatic cancer tumors. We uncover several structural features for the ligands that can be used to improve their binding and efficacy. Second, we discuss the AlkB family of enzymes. AlkB is the E. coli DNA repair protein for alkylation damage, and has human homologues with slightly different functions and substrates. Each has a conserved active site with a catalytic iron and a coordinating His...His...Asp triad. We have applied molecular dynamics (MD) to investigate the effect of a novel single nucleotide polymorphism for AlkBH7, which is correlated with prostate cancer and has an unknown function. We show that the mutation leads to active site distortion, which has been confirmed by experiments. Thirdly, we investigate the unfolding of hen egg white lysozyme in 90% ethanol solution and low pH, to show the initial steps of unfolding from a native-like state to the disease-associated beta-sheet structure. We compare to mass spectrometry experiments and also show differing pathways based on protonation state. Finally, we discuss three different DNA polymerase systems. DNA polymerases are the primary proteins that replicate DNA during cell division, and have various extra or specific functions. We look at a proofreading-deficient DNA polymerase III mutant, the effects of solvent on DNA polymerase IV's ability to bypass bulky DNA adducts, and a variety of mutations on DNA polymerase kappa.
The Correlation between Information Literacy and Critical Thinking of College Students: An Exploratory Study
Authors:   , McMullin Shelly Lynne
Published: February 2025

This exploratory, mixed-methods study investigated the relationship between information literacy and critical thinking. The research question guiding the first portion of the study was: How do information literacy and critical thinking relate in undergraduate students conducting academic research? Using two standardized assessments, the study assessed the information literacy and critical thinking skills of a small population of college students from a private, university in Texas. The correlational analysis of the scores from the two assessments showed a statistically significant, positive, moderate correlation. The study also explored the likelihood of gender differences in cognitive processing using information literacy and critical think skills assessments. The independent samples t-tests for both assessments demonstrated no statistically significant differences between female and male participants. Finally, a qualitative component comprised of a questionnaire provided context to the assessment scores through items requesting information on participant source selection priorities via the three middle stages of Kuhlthau's information search process model as well as their criteria for selecting sources of information. Though only a small number of the participants completed the questionnaire, the responses highlighted areas of interest for future research.
Non-Resonant Uniserial Representations of Vec(R)
Authors:   , O'Dell Connor
Published: February 2025

The non-resonant bounded uniserial representations of Vec(R) form a certain class of extensions composed of tensor density modules, all of whose subquotients are indecomposable. The problem of classifying the extensions with a given composition series is reduced via cohomological methods to computing the solution of a certain system of polynomial equations in several variables derived from the cup equations for the extension. Using this method, we classify all non-resonant bounded uniserial extensions of Vec(R) up to length 6. Beyond this length, all such extensions appear to arise as subquotients of extensions of arbitrary length, many of which are explained by the psuedodifferential operator modules. Others are explained by a wedge construction and by the pseudodifferential operator cocycle discovered by Khesin and Kravchenko.
Leaving the Classroom: A Multiple Case Study on the Experiences of Black Women who Transitioned from Teaching to a Non-Teaching Role
Authors:   , Booker Standra Nicole
Published: February 2025

This qualitative multiple case study aims to describe the experiences of two Black women who chose to leave the classroom and transition to other roles within the field of education. Using metaphorical analysis, this study employed the four-capital theoretical framework. This framework connects human capital, structural capital, social capital, and positive psychological capital as factors related to teacher attrition and retention. This study illustrates how the participants' experiences fit into the four-capital theoretical framework and highlights the metaphors the participants use to describe their transition. The researcher conducted two semi-structured open-ended interviews in which the participants were asked to describe their experiences in the classroom as well as their experiences in their new positions. The researcher analyzed the metaphors used by the participants and categorized their responses based on the four capitals. The identified metaphors offered a vivid description of the participants' experiences. The results indicated that although the experiences of the participants are similar to those found throughout the literature, the four-capital theory helps describe their experiences more holistically. Rather than having isolated reasons for leaving the classroom, the attrition of the participants can be explained by examining the interconnectedness of the various capitals. These findings suggest that teacher retention and attrition be studied by looking at a variety of causes as opposed to isolated factors.
Superbursts: Investigation of Abnormal Paroxysmal Bursting Activity in Nerve Cell Networks In Vitro
Authors:   , Suri Nikita
Published: February 2025

Superbursts (SBs) are large, seemingly spontaneous activity fluctuations often encountered in high density neural networks in vitro. Little effort has been put forth to define and analyze SBs which are paroxysmal bursting discharges. Through qualitative and quantitative means, I have described specific occurrences of superbursting activity. A complex of paroxysmal bursting has been termed a "superburst episode," and each individual SB is a "superburst event" which is comprises a fine burst structure. Quantitative calculations (employing overall spike summations and coefficient of variation (CV) calculations), reveal three distinct phases. Phase 1 is a "build up" phase of increasingly strong, coordinated bursting with an average of a 17.6% ± 13.7 increase in activity from reference. Phase 2, the "paroxysmal" phase, is comprised of massive coordinated bursting with high frequency spike content. Individual spike activity increases by 52.9% ± 14.6. Phase 3 is a "recovery phase" of lower coordination and an average of a 50.1% ± 35.6 decrease in spike production from reference. SBs can be induced and terminated by physical manipulation of the medium. Using a peristaltic pump with a flow rate of 0.4ml/min, superbursting activity ceases approximately 28.3 min after the introduction of flow. Alternatively, upon cessation of medium flow superbursting activity reemerges after approximately 8.5 min. Additionally, this study explored other methods capable of inducing superbursting activity using osmotic shocks. The induction and termination of SBs demonstrates that the cell culture environment plays a major role in generating this phenomenon. The observations that high density multi-layer neuronal networks in culture are more likely to enter paroxysmal bursting also supports the hypothesis that enrichment and depletion layers of metabolites and ionic species are involved in such unusual activity. The dynamic similarity of the SB phenomenon with epileptiform discharges make further quantification on the spike pattern level pertinent and important.
Cultural Influence on Attachment and Psychopathic Traits
Authors:   , Lasslett Heather Elicia
Published: February 2025

Individuals evidencing psychopathic personality traits have been shown to have problematic attachment to others. Moreover, research suggests that culture affects attachment style as well as the expression of various psychopathic traits using the four-factor model of psychopathy. However, the majority of this research has included only white college students, which is a limiting factor. The current study assessed the relations among attachment representations and psychopathic features across two independent samples (one adult & one adolescent) from different world regions (adults only), ethnicity (adolescents only), and gender. Using similar assessments of attachment and psychopathic traits for both samples, dismissing attachment was related to aspects of psychopathic traits in nearly all cultures and ethnicities sampled. In the world sample, secure attachment was found to positively relate to impulsive and parasitic lifestyle traits in all regions. Culture and gender were found to moderate several relations between specific attachment styles and psychopathic features. Overall, the patterns of data indicated that many of the differences found between groups may be rooted in individualistic versus collectivistic values, and were consistent with previous research assessing these constructs across diverse samples.
Use of Bio-Product/Phase Change Material Composite in the Building Envelope for Building Thermal Control and Energy Savings
Authors:   , Boozula Aravind Reddy
Published: February 2025

This research investigates the bio-products/phase change material (PCM) composites for the building envelope application. Bio-products, such as wood and herb, are porous medium, which can be applied in the building envelope for thermal insulation purpose. PCM is infiltrated into the bio-product (porous medium) to form a composite material. The PCM can absorb/release large amount of latent heat of fusion from/to the building environment during the melting/solidification process. Hence, the PCM-based composite material in the building envelope can efficiently adjust the building interior temperature by utilizing the phase change process, which improves the thermal insulation, and therefore, reduces the load on the HVAC system. Paraffin wax was considered as the PCM in the current studies. The building energy savings were investigated by comparing the composite building envelope material with the conventional material in a unique Zero-Energy (ZØE) Research Lab building at University of North Texas (UNT) through building energy simulation programs (i.e., eQUEST and EnergyPlus). The exact climatic conditions of the local area (Denton, Texas) were used as the input values in the simulations. It was found that the EnergyPlus building simulation program was more suitable for the PCM based building envelope using the latent heat property. Therefore, based on the EnergyPlus simulations, when the conventional structure insulated panel (SIP) in the roof and wall structures were replaced by the herb panel or herb/PCM composite, it was found that around 16.0% of energy savings in heating load and 11.0% in cooling load were obtained by using PCM in the bio-product porous medium.
An Exploratory Mixed Method Study of Gender and Sexual Minority Health in Dallas: A Needs Assessment
Authors:   , Bonds Stacy
Published: February 2025

Gender and sexual minorities (GSM) experience considerably worse health outcomes than heterosexual and cisgender people, yet no comprehensive understanding of GSM health exists due to a dearth of research. GSM leaders in Dallas expressed need for a community needs assessment of GSM health. In response to this call, the Center for Psychosocial Health Research conducted a needs assessment of gender and sexual minority health in Dallas (35 interviews, 6 focus groups). Competency was one area highlighted and shared across existing research. Thus, the current study explored how competency impacts gender and sexual minorities' experience of health care in Dallas. We utilized a consensual qualitative research approach to analyze competency-related contents. The meaning and implications of emerging core ideas were explored. These findings were also used to develop a survey instrument.
Effects of a Single Bout of Exercise on Neurocognitive Function following Acute Sleep Restriction
Authors:   , Carmichael Kaitlyn E.
Published: February 2025

Acute sleep loss may lead to elevated fatigue, decreased energy, and diminished cognitive performance. Traditionally, sleep extension is used to restore mood and cognitive function to baseline levels following insufficient sleep, yet this method may not be feasible or preferred. Acute exercise may serve as an affordable and relatively safe intervention to reduce detriments to daytime functioning following sleep loss. The primary purpose of this study was to examine the effects of moderate-intensity aerobic exercise on neurocognitive function following acute sleep restriction. A secondary aim was to examine the effects of exercise in subjective reports of fatigue, energy, and sleepiness following acute sleep restriction. Fifty-six participants, matched by sex, age, and chronotype, were randomly assigned to either an exercise (EX) or seated control (SC) condition. Following a 4-hour sleep restriction protocol, participants completed the oddball paradigm before and after 20 minutes of exercise or stationary sitting. P3 amplitude and latency, arousal, sleepiness, energy, and fatigue were assessed during the experiment. After controlling for pre-test differences, P3 latency was significantly faster following exercise relative to the control group. No significant P3 amplitude differences were observed between conditions. The EX group displayed significant improvements in arousal, sleepiness, energy, and fatigue compared to the SC group. Findings suggest that 20 minutes of moderate-intensity aerobic exercise following acute sleep restriction may improve cognitive processing speeds, as well as improve arousal, sleepiness, energy, and fatigue.
Effects of Deepwater Horizon Crude Oil on Visual Function in Teleost Fishes
Authors:   , Magnuson Jason T
Published: February 2025

The Deepwater Horizon oil spill released millions of barrels of oil into the Gulf of Mexico, impacting economically and ecologically important fishes. Polycyclic aromatic hydrocarbons (PAHs) present in the oil have been shown to cause developmental impairments in early life stage fishes, such as morphological and behavioral changes related to eye formation and visual processing following PAH exposure. Prior research reported reduced eye growth in open water, pelagic species, as well as reduced photoreceptor-specific transcription factors associated with eye development following exposure to crude oil. Though changes in transcriptomic-level pathways associated with vision and visual processing have been reported, it has yet to be determined how these changes relate to physiological or behavioral-level effects in fish. Therefore, the present studies evaluated the effect of weathered crude oil on eye development and visual function in mahi-mahi, red drum, sheepshead minnow, and zebrafish larvae. Fish were assessed through several visually-mediated behavioral assays, analyzed histologically and immunohistologically, along with subsequent transcriptomic analyses and associated gene expression changes. Larvae exposed to crude oil experienced significantly reduced abilities to exhibit optomotor or optokinetic responses relative to controls, with associated reductions in retinal development. Furthermore, genes associated with eye development and phototransduction were downregulated, with subsequent decreases in the immunofluorescence of neurological connections within the retina and a choroid-specific increase in apoptotic activity. We related oil-induced transcriptomic-level effects to morphological, physiological, and behavioral-level impairments in larval teleost fishes.
Validating the National Institutes of Health Brief Fatigue Inventory and Characterizing Fatigue Symptoms across Patient Populations
Authors:   , Martinez-Kaigi Valerie T
Published: February 2025

A gold standard measurement does not exist to assess fatigue symptoms across patient populations. Current tools only consist of self-report measures that may not assess fatigue objectively. The National Institutes of Health-Brief Fatigue Inventory (NIH-BFI) is a clinician-administered instrument developed as a more objective assessment of fatigue symptoms. This study assessed the NIH-BFI's validity in diverse clinical populations, which included patients diagnosed with a mood disorder, Parkinson's disease, cancer, and healthy controls. Results suggest good criterion-related and convergent validity for the NIH-BFI. Results also indicate significant differences in fatigue severity between cohorts. Moreover, the data also suggest significant differences among groups in depression, anxiety, pain catastrophizing, sleep quality, global mental and physical health, and cognitive functioning. This study proposes that the NIH-BFI is a valid clinician-administered measure of fatigue that can be administered in multiple clinical populations.
Depiction through Evocation, Representation, and Introspection: An Examination of David Maslanka's Unaccompanied Marimba Solos
Authors:   , Robinson Corey
Published: February 2025

The primary purpose of this study is to provide connections between a formal motivic analysis and the programmatic content of David Maslanka's three works for unaccompanied marimba: Variations on Lost Love (1977), My Lady White (1980), and A Solemn Music (2013). A comparison of the compositional process of each of these works is proposed through terms of Maslanka's use of depiction. Depiction is the action or result of representing through drawing, painting, or other art form, in this case, music. In each work for unaccompanied marimba, Maslanka uses this process of depiction in a unique way. The depictive mediums are categorized as evocative, representative, and introspective and these distinct approaches to depiction lead to three drastically different musical works. The different methods of depicting source materials are the distinguishing characteristics that separate these three works for solo marimba. This document includes a motivic analysis and comparisons of compositional devices used in these three works. A brief overview of Maslanka's life and works as well as a listing of all of his works that feature percussion instruments are also included.
Naming and Shaming Non-State Organizations, Coercive State Capacity, and Its Effects on Human Rights Violations
Authors:   , Martinez Melissa
Published: February 2025

Scholars generally assume that states are shamed for their own behavior, but they can also be shamed for the lack of investigation for violence perpetrated by domestic non-state actors. I engage this previously-unstudied phenomenon and develop a theory to explain how states will respond to being shamed for failing to control domestic violence. I examine two types of outcomes: the governments' change in behavior, and the accountability efforts against state agents that have abused human rights. For the government's reaction to being shamed for violence from non-state organizations, I develop a theory to examine changes in coercive state capacity – including military and police personnel – since this reaction may largely exacerbate human rights violations. I hypothesize that states shamed due to abuses by violent non-state organizations (VNSO) will increase military personnel to halt criminal violence and respond to the international spotlight. I then examine the relationship between naming and shaming states over physical integrity abuses by different types of perpetrators and human rights prosecutions. Using newly coded data on the types of perpetrators shamed in the United Nations Human Rights Council (UNHRC) country reports, I find that shaming over abuses that include VNSO as perpetrators decreases the likelihood of expanding their police force when the state has the military patrolling the streets and is likely to increase the predicted number of police prosecutions, particularly if the shaming is over killings from VNSOs. Lastly, I examine how changes in coercive capacity affect human rights violations and the number of violent episodes from VNSOs.
The Use of Technology in Early Childhood Schools and Homes and Its Impact on the Social and Language Development of Children: Perspectives of Parents and Teachers in Kuwait
Authors:   , Alsuhail Saffa Z A J Zaid
Published: February 2025

This study was aimed at understanding the use of technology in early childhood school and home settings as well as its impact on students' social and language development, specifically with children aged four to seven from two schools (Kindergarten and elementary) in Kuwait. The study followed a qualitative design in which the interpretative approach was applied. Non-participant observations were conducted to gather data concerning the actual use of technology in the classrooms, they were followed by interviews with teachers and a group of parents from each classroom. The study used Vygotsky's social development theory as a framework for the analysis of data. The analysis showed limitations in the use of technology in the classroom; teachers identified a need for training to increase their knowledge about how to integrate technology into instruction. Also, the limited availability of up-to-date technology was viewed as a challenge. Teachers and parents agreed that the use of technology may foster social and language development for most students, on the condition that their use is supervised and guided by an adult. However, they also perceived that technology could have a negative impact on the development of students' social development, an area that requires further investigation.

Religious Identity and Interreligious Communications: Predicting In-Group and Outgroup Bias with Topic-Sentiment Analysis
Authors:   , Grigoropoulou Nikolitsa
Published: February 2025

Intergroup relations and the factors affecting them constitute a subject of recurring interest within the academic community. Social identity theory suggests that group membership and the value we assign to it drives the expression of in-group favoritism and outgroup prejudice, among other intergroup phenomena. The present study examines how (ir)religious identities are related to topic-sentiment polarization in the form of positive in-group and negative outgroup bias during interreligious debates in YouTube commentaries. Drawing from the propositions of social identity theory, six hypotheses were tested. The data for the study, a product of a natural experiment, are comments posted on YouTube commentary sections featuring videos of interreligious debates between (a) Christian and atheist or (b) Christian and Muslim speakers. Using topic-sentiment analysis, a multistage method of topic modeling with latent semantic analysis (LSA) and sentiment analysis, 52,607 comments, for the Christian - atheist debates, and 24,179 comments, for the Christian - Muslim debates, were analyzed. The results offer support (or partial support) to the hypotheses demonstrating identity-specific instances of topic-sentiment polarization to the predicted direction. The study offers valuable insights for the relevance of social identity theory in real-world interreligious interactions, while the successful application of topic-sentiment analysis lends support for the more systematic utilization of this method in the context of social identity theory.
Interpersonal Functioning and Experiential Avoidance: Considering New Measurements and Their Implications
Authors:   , Steinberg Daniel
Published: February 2025

Interpersonal functioning can be conceptualized as being comprised of social skills, connectedness, social cognition, and intimacy. A concept that is related to an examination of interpersonal functioning is experiential avoidance (EA), which can be defined as an unwillingness to experience or remain in contact with unpleasant private events through attempts to avoid or escape from these experience. An examination of EA and interpersonal functioning has not previously taken place. This study thus sought to fill that gap in the literature. The availability of a behavioral-oriented measure of interpersonal functioning aided in this investigation. The relationship of EA and interpersonal functioning to depression and anxiety were also examined, in order to evaluate their relative contributions to psychopathology. Overall, it was found that EA and interpersonal functioning were significantly related. However, the dimensions of EA varied in strength with respect to their relationships with interpersonal functioning. Further, it was found that interpersonal functioning predicted unique variance in both depression and anxiety, and partially mediated the relationship between EA and both anxiety and depression. These results might guide the development of treatment programs and add support to the use of treatments with trans-diagnostic targets.
Mental Illness Stigma, Parent-Child Communication, and Help-Seeking of Young American Adults with Immigrant Parents
Authors:   , Bismar Danna
Published: February 2025

This study examined a mediational model of mental illness stigma, parent-child communication about mental health concerns, and help seeking attitudes/behaviors among young adults with at least one immigrant parent while considering the possible moderating effect of acculturation gap. The primary goal of this study was to examine whether the acculturation gap changed the relation between mental illness stigma and communication about personal mental health concerns with immigrant parents, which in turn could become a significant predictor of their help-seeking attitudes, as well as a barrier to seeking professional mental health services. Findings provided support to the direct and indirect effects of mental illness stigma through communication about mental health concerns on attitudes about help-seeking. The acculturation gap hypothesized to be a possible moderator for the stigma-communication about mental health concerns relationship among young adult ABCI was found to be significant for ABCI with a low mainstream culture acculturation gap. Discussion on the findings, limitations of the study, future research directions, and counseling implications are addressed.
It's the Kids!: Examining Early-Career Elementary General Music Teacher Longevity in Title I Settings
Authors:   , Chandler Michael Douglas
Published: February 2025

The purpose of this study was to investigate factors contributing to the longevity of four early-career (5 to 10 years of experience) K–5 elementary general music teachers in Title I schools situated in four regions of the United States. The central research question was: How did early-career elementary general music teachers in Title I schools describe the opportunities and challenges that contributed to their decisions to continue teaching? Using Deci and Ryan's theory of self-determination as a theoretical framework, I analyzed how the four teachers reflected on the degree to which they each possessed autonomy, competence, and relatedness through recounting their perspectives, stories, and experiences. Although the participants shared many commonalities, they also experienced challenges and opportunities unique to their teaching environments. Results were mixed regarding their levels of autonomy and relatedness, but all four teachers possessed a high level of competence, which was likely a contributing factor to their longevity and potential to continue teaching. Nurture and care for children also emerged as a prominent theme from the results, which required the application of a separate theoretical framework. Noddings's theory of the ethic of care served as a lens for examining the myriad ways each participant demonstrated love, care, and concern for her students. All four teachers strongly expressed the important role their love of working with children and seeing them grow, progress, and learn played in their desire to continue teaching. Of all the contributing factors, the participants' ethic of care seemed to be the most significant influence on their decisions to continue teaching. They also spoke extensively about the role of their love for music as a subject. Conclusions address implications for the field and recommendations for future research.
Applications of Metallic Clusters and Nanoparticles via Soft Landing Ion Mobility, from Reduced to Ambient Pressures
Authors:   , Aguilar Ayala Roberto
Published: February 2025

Nanoparticles, simple yet groundbreaking objects have led to the discovery of invaluable information due to their physiological, chemical, and physical properties, have become a hot topic in various fields of study including but not limited to chemistry, biology, and physics. In the work presented here, demonstrations of various applications of chemical free nanoparticles are explored, from the determination of a non-invasive method for the study of the exposome via using soft-landing ion mobility (SLIM) deposited nanoparticles as a matrix-assisted laser desorption/ionization (MALDI-MS) matrix replacement, to the direct SLIM-exposure of nanoparticles onto living organisms. While there is plenty of published work in soft-landing at operating pressures of 1 Torr, the work presented here shows how this technology can be operated at the less common ambient pressure. The ease of construction of this instrument allows for various modifications to be performed for a wide array of applications, furthermore the flexibility in metallic sample, operating pressure, and deposition time only open doors to many other future applications. The work presented will also show that our ambient SLIM system is also able to be operated for toxicological studies, as the operation at ambient pressure opens the door to new applications where vacuum conditions are not desired.

Published: February 2025

This study applied the impression management theory in the context of social networking to investigate the generalized research question of this dissertation which is "Do active social media presence and various privacy concerns influence online behaviors of students on social media?" The results and conclusions are presented via the conduct of three different studies and the summary provides insights and explain the overall contribution of the research. For each study we developed a research model for which data was collected separately for each of these models. Hypotheses of each model were tested by partial least squares- structural equation modeling techniques using SmartPLS 2.0. Our findings confirm the hypotheses and showed that all the predictors positively influence online social networking behaviors. Active social media presence is operationalized as predictors such as SNS stalking awareness, Selective disclosure, desired differential persona, impression motivation, and information trustworthiness. Privacy concerns have been operationalized as SNS privacy awareness, technology awareness. Online behaviors have been operationalized as responsible image and reckless image.
A Cross-Cultural Study of Adult Attachment, Social Self-Efficacy, Familismo, and Psychological Wellbeing
Authors:   , Zamudio Leal Gabriel Mario
Published: February 2025

Although Latinos are the largest minority group in the country, research examining how different psychological and cultural variables affect Latino individuals' wellbeing is disproportionately developed and cross-cultural comparison studies are particularly scarce. To address these issues, this dissertation research examined cross-cultural adult attachment-social self-efficacy-psychosocial wellbeing conceptual mediational model while investigating the moderator effects of country membership and familismo on the proposed mediational model using a cross-cultural sample of Mexican and Mexican-American university students. A total of 595 participants, including 360 Mexican students from Mexico and 235 Mexican-American students from the United States completed the research questionnaires. Results indicated that social self-efficacy was a significant mediator for the effects of insecure attachment on life satisfaction and conflict resolution in both cultural groups and for the links between attachment insecurity and depressive symptoms in the Mexican-American group. Additionally, moderated mediation analyses showed that country membership was a significant moderator for the links between attachment avoidance and social self-efficacy when life satisfaction, conflict resolution style, and depressive symptoms were the dependent variables, as well as for the direct link between attachment anxiety and physical health symptoms. Familismo was also found to be a significant moderator for the direct effects of attachment anxiety on physical health symptoms and life satisfaction in both groups. Findings are discussed from the attachment and cross-cultural perspectives. Counseling implications, limitations, and future research directions are offered.
"Her Name Was"
Authors:   , Almendariz Sergio E
Published: February 2025

Her Name Was is an examination of the oppression of transgender people in a society that is built on the nominalization of cisgender people, those who gender matchers their sex assigned at birth, and how this oppression lends itself to violence. In the summer of 2015, the body of Shade Schuler, an African American transgender woman, was found in a field outside of Dallas, Texas. Ms. Shade is part of an alarming epidemic of escalating levels of targeted violence against the transgender community. This documentary pulls back the curtain as it captures the feelings and struggles of the transgender community as they attempt to navigate and survive in a cis dominating society.
Do Banks' Dividends Signal Their Financial Health?
Authors:   , Zheng Yi
Published: February 2025

This paper examines the relation between banks' dividends and their future financial health. Using banks' Nonperforming Loans Ratio, Loan Loss Provision Ratio, and Z-score as proxies for their financial health, I show that there is a strong positive relation between banks' dividends lagged by one quarter and their financial health in the current quarter. This main finding continues to hold following several additional tests, including the application of an instrumental variable approach, the use of change in dividends as the key independent variable, the exclusion of banks that are subject to stress test, the addition of macroeconomic variables, the exclusion of too-big-to-fail banks, and the exclusion of non-depository banks. I also find that the positive relation between banks' dividends and their future financial health is more pronounced for banks with a higher degree of opacity, a lower Tier 1 capital ratio, and during the 2007-2009 financial crisis. This paper contributes to three strands of the finance literature, including the Risk Reduction Hypothesis of dividend signaling in corporate finance, bank dividend policies, and the determinants of banks' financial stability. First, I show that there is a positive relation between banks' dividends lagged by one quarter and their financial health in the current quarter, also meaning that banks' dividends are negatively associated with their future risk conditions. This finding is consistent with the Risk Reduction Hypothesis regarding dividend signaling. Second, Floyd, Li, and Skinner (2015) propose a new idea that banks use dividends to signal financial health, and they rely on this idea to explain why banks have a higher and more stable propensity to pay dividends vis-à-vis industrials during the past several decades. My finding that banks' dividends are positively associated with their future financial health empirically supports this idea proposed by Floyd, Li, and Skinner (2015). Last, to my knowledge, no prior study has attempted to extensively detect a direct relation between banks' dividends and their financial stability. I fill this gap by investigating whether this relation exists. I show that banks' dividends have significantly positive explanatory power on their future financial stability, as proxied by three risk conditions.
Psychosocial Predictors of Eating Disorder Classification: Longitudinal and Cross-Sectional Analyses
Authors:   , Tackett Bailey Price
Published: February 2025

There is growing concern for eating pathology and body dissatisfaction in sports; particularly, in sports that emphasize a lean body type. In 325 female collegiate swimmers/divers and gymnasts, we examined psychosocial well-being (i.e., perception of weight pressures, levels of internalization, body satisfaction, dietary intent, negative affect) at the beginning and end of an athletic season and predict their eating disorder classification at the end of their athletic season. Logistic regressions revealed that a model containing all 14 predictors at the beginning and end of an athletic season significantly predicted eating disorder classification at the end of an athletic season. Specifically, in the longitudinal logistic regression, with every one unit of increase on a measure of the pressure felt within the sport environment regarding their weight and every unit increase on a measure of their intentions to diet, respectively, the female athletes were 49% and 89% more likely to be classified in the subclinical/clinical group at the end of their sport season. Surprisingly, with every one unit of increase on a measure of sociocultural pressure to exercise, female athletes were 43% less likely to be classified in the subclinical/clinical group six months later. The cross-sectional logistic regression found that only dietary restraint was significant. Specifically, with every one unit of increase on a measure of their intentions to diet the female athletes were 3.6 times more likely to be classified in the subclinical/clinical group at the end of their sport season. The implications of this study may emphasize the importance of body healthy sport systems to reduce sport specific pressures and dieting among female collegiate athletes. Limitations of this study include self-report measures and longitudinal timeframe was only across one athletic season.
Utilizing Rapid Mass Spectrometry Techniques to Profile Illicit Drugs from Start to Finish

The increasingly complex world of illicit chemistry has created a need for rapid, selective means of determining the threat posed by new drugs as they are encountered by law enforcement personnel. To streamline this process, the entirety of the problem, from the production of illicit drugs all the way to the final analysis have been investigated. A series of N-alkylated phenethylamine analogues were synthesized in a shotgun method and subjected to direct-infusion analysis. A range of products were detected without the need for time-consuming purification steps, which was extended to novel pharmacological and receptor-binding assays where mass spectrometry is used as a detector. This direct-infusion technique was also applied to studies of methamphetamine and fentanyl production to preemptively determine improvements to common reaction conditions and explore the origins of common impurities. The ability to utilize these rapid techniques directly from the fume hood has also been critically reviewed to highlight gaps in current research and opportunities for improvement. When combined, these studies seek to provide a means for rapid, simplified analysis of illicit drugs to improve the quality of data and dramatically increase throughput.
The Role of Self-Criticism in Direct and Indirect Self-Harming Behaviors

Nonsuicidal self-injury (NSSI) is a form of direct self-harm that involves willful damage to bodily tissue without suicidal intent; it includes behaviors such as cutting, burning, carving, biting, scraping, and scratching of the skin, as well as hitting and skin and scab picking. Engagement in NSSI has been shown to relate to a host of maladaptive states and outcomes, including depression, anxiety, poor emotion regulation, and suicidal ideation and attempts. Socially sanctioned forms of body modification (e.g. tattoos and piercings) have received less attention as potential self-harm outlets, but have been posited to represent similar physical outlets of emotional pain. Indirect self-harm, in contrast, can include behaviors such as substance abuse, disordered eating, participation in abusive relationships, and sexual risk-taking. Extant literature suggests that self-harm in either form is associated with higher levels of self-criticism than healthy adults endorse. However, few studies have examined self-criticism in each of these self-harming subgroups. Female participants were recruited online using Amazon's Mechanical Turk. Results from the present study indicate that 1) direct self-harming individuals are considerably more self-critical than indirect self-harmers and control subjects, 2) those who engage in multiple forms of self-harm are more self-critical than those engaging in only one form, 3) self-criticism did not significantly predict self-harming behaviors, and 4) there are no significant differences in self-criticism based on developmental trajectory of self-harming behaviors. Additionally, individuals with body modification (e.g. tattoos, piercings) did not exhibit different levels of self-criticism than those without socially sanctioned alterations. Implications, limitations, and future directions for research of this nature are discussed.
A Multi-Modal Insider Threat Detection and Prevention based on Users' Behaviors

Published: February 2025

Insider threat is one of the greatest concerns for information security that could cause more significant financial losses and damages than any other attack. However, implementing an efficient detection system is a very challenging task. It has long been recognized that solutions to insider threats are mainly user-centric and several psychological and psychosocial models have been proposed. A user's psychophysiological behavior measures can provide an excellent source of information for detecting user's malicious behaviors and mitigating insider threats. In this dissertation, we propose a multi-modal framework based on the user's psychophysiological measures and computer-based behaviors to distinguish between a user's behaviors during regular activities versus malicious activities. We utilize several psychophysiological measures such as electroencephalogram (EEG), electrocardiogram (ECG), and eye movement and pupil behaviors along with the computer-based behaviors such as the mouse movement dynamics, and keystrokes dynamics to build our framework for detecting malicious insiders. We conduct human subject experiments to capture the psychophysiological measures and the computer-based behaviors for a group of participants while performing several computer-based activities in different scenarios. We analyze the behavioral measures, extract useful features, and evaluate their capability in detecting insider threats. We investigate each measure separately, then we use data fusion techniques to build two modules and a comprehensive multi-modal framework. The first module combines the synchronized EEG and ECG psychophysiological measures, and the second module combines the eye movement and pupil behaviors with the computer-based behaviors to detect the malicious insiders. The multi-modal framework utilizes all the measures and behaviors in one model to achieve better detection accuracy. Our findings demonstrate that psychophysiological measures can reveal valuable knowledge about a user's malicious intent and can be used as an effective indicator in designing insider threat monitoring and detection frameworks. Our work lays out the necessary foundation to establish a new generation of insider threat detection and mitigation mechanisms that are based on a user's involuntary behaviors, such as psychophysiological measures, and learn from the real-time data to determine whether a user is malicious.
