Insights into the Complex Relationship Between Independent Manufacturers' Representatives and Their Principals
Authors:   , Bergestuen Trond
Published: February 2025

Independent manufacturers' representatives (IMRs) are companies that sell products on behalf of manufacturers (principals), typically on a commission basis. IMRs offer principals specialized knowledge about product areas or markets, and they can function as attractive supplements or replacements for in-house sales units. The literature on IMRs' allocation of resources to their principals and the downstream impact on performance is underexplored. A paucity of published research exists using actual IMR sales and commission data, likely because this data is difficult to collect due to its sensitive nature. This dissertation fills this gap by exploring the influence of principals' use of sales controls, how these controls impact the psychological climate that arises between IMRs and their principals, and the downstream impact on IMRs' allocation of sales resources and the sales volumes actually produced. Furthermore, this dissertation answers the call for research on the impact of principal's use of house territories and house accounts, through the lens of the IMR. The dissertation features three essays. The purposes are: to identify gaps in existing IMR research in order to provide directions for future research in this domain; to explore the influence of the principal's sales controls on the psychological climate between the principal and IMR and the downstream impact on IMR allocation of sales resources and sales performance; and to develop theoretical and practical insights about the impact of principals' use of house accounts, i.e. customers served by an in-house sales organization, inside or outside IMRs' territories.
Achievement Motivation Theory as a Model for Explaining College Athletes' Grit
Authors:   , Albert Erin
Published: February 2025

This study examined the direct and indirect associations of the perceived coach-created motivational climate, athletes' implicit theory, and athletes' achievement goal orientation in relation to their levels of grit. Five hundred twenty-three Division I and II collegiate student-athletes (male = 246, female = 277) from five institutions across the south-central and southeast areas of the United States completed self-report measures assessing the previously described constructs. The measurement model fit the data well (SRMR = .055; CFI = .938; RMSEA = .067) and demonstrated invariance across the male and female athletes. The structural model demonstrated adequate fit (SRMR = .088; CFI = .918; RMSEA = .068). All direct and indirect paths in the model were significant in the expected direction, with the exception of the direct path from entity theory to ego goal orientation and the indirect path from ego-involving climate to ego goal orientation through entity theory, which were both non-significant. The mastery-incremental constructs accounted for 65% of the variance in grit. Results indicate that achievement motivation theory is an appropriate framework through which to examine grit, and achievement motivation constructs may be significant antecedents of grit's development. Limitations and future directions are discussed.
Variability in the Natural World: An Analysis of Variability in Preschool Play
Authors:   , Armshaw Jared T
Published: February 2025

Children acquire many skills through play. These range from fine and gross motor skills, social skills, problem-solving, to even creativity. Creativity or creative engagement is frequently a component in early preschool curricula. A pivotal repertoire to engage in behaviors deemed creative, such as art, storytelling, problem-solving, and the like, is the ability to vary one's responses regardless of the specific repertoire. Researchers have developed methods to produce response variability. However, notwithstanding the significant contributions from the literature for prompting response variability, it remains unclear how much variation in responding is socially appropriate. To fill this research gap, the purpose of this study is to characterize and understand the different ways preschool children commonly interact with the activities and materials present in a preschool classroom. In our study, we assessed children's repeat item interactions, novel item interactions, and time allocation across seven concurrently available activity centers. A multifarious pattern for item interactions emerged across children. Some children had restricted levels of novel item and center interactions, while other children had more varied novel item and center interactions. However, the variance in interactions was predominantly controlled by the center type. This study bolsters our understanding of variability and creativity within a school setting, but more importantly, it informs the task of selecting goals for applied practice with children who have restricted play or interests.
An Analytical Study of Isang Yun's "Oboe and Oboe D'amore Concerto": The Intercultural Adaptation of Sigimsae for the Korean Piri with Modern Western Compositional Techniques for the Oboe
Authors:   , Oh Eun Suk
Published: February 2025

Isang Yun (1917-1995), one of the most important avant-garde German-Korean composers, is perhaps best known for his success at integrating Korean musical elements into traditional Western styles. His Concerto for Oboe, Oboe d'amore, and Orchestra incorporates many traditional Korean elements, and uses techniques such as Hauptton, Hauptklang, and Umspielung to blend these elements into a Western musical style. This study explores the elements of traditional Korean music and instruments present in Yun's score, examines his compositional techniques, and makes practical performance suggestions that allow performers to properly convey his intentions. This dissertation includes six chapters. The first chapter discusses the purpose and importance of the study. The second chapter reviews Isang Yun's biography and works, based on a published interview with Yun and a biography written by his wife of many years. The third chapter introduces the characteristics of traditional Korean woodwind instruments relevant to the work. The fourth chapter examines Yun's compositional techniques of Hauptton, Hauptklang, and Umspielung in the work and their relationship with the main-tone and Sigimsae techniques. The fifth chapter introduces and explores different types of Sigimsae in the work, with suggestions for quarter-tone performance techniques. The sixth and last chapter is a conclusion.
Where We Split
Authors:   , Paramo Sebastian Hasani
Published: February 2025

Nearly 30 years after its publication Gloria E. Anzaldúa's book Borderlands/La Frontera: The New Mestiza remains more relevant than ever, particularly her discussion of borderlands as more than physical boundaries. In her book, she theorizes and explores how borders can possess psychic, social, and geopolitical qualities, and in order to articulate the nuances and challenges of border-culture, she invents a new language for underrepresented poets to discuss their poetics. The goal in crafting this essay is to reclaim Anzaldúa as an author worthy of consideration for her poetics. History and bloodlines are central to Anzaldúa's argument that poetry allows for language to transform violence, or historical and bloodline traumas, into one's own new myth-making. The capacity to redefine a border and make it borderless is discussed through the works of Natalie Scenter-Zapcio and Vanessa Angélica Villarreal's poems, in addition to a few key anthologies and my own collection, which seeks to sit in ambiguities and to reclaim and affirm histories. Ultimately, conversations about the poetics of Anzaldúa and her influence on other poets should expand our discussion of American poetics. Her focus on "psychic unrest" gives power to language over ambiguity and could be greatly useful to other poets beyond the border.
The Experiences of Black Transracially Adoptive Parents
Authors:   , Conner Charmaine Lanae
Published: February 2025

The purpose of this transcendental phenomenological inquiry was to explore the experiences of adoptive parents who have Black transracially adopted children. More specifically, I sought to understand how the parents perceived their child's cultural and racial identity development and how they perceived the child-parent relationship. Therefore, I used the cultural-racial identity model created for transracial adoptees as a theoretical framework to answer the following questions: What are Black transracially adoptive parents' perceptions of their child's racial/cultural identity development? What are Black transracially adoptive parents' perceptions of the parent-child relationship? Upon approval from the Institutional Review Board, six transracially adoptive parents with Black transracially adopted children participated in this study. Participants engaged in a 60-minute interview that was transcribed and coded to develop themes consistent with other participants. There were six themes identified from the data: (a) experience of the child-parent relationship, (b) impact of trauma, (c) becoming a transracially adoptive parent, (d) cultural, racial, ethnic, identity development process (CREID), (e) encounters with microaggressions, and (f) cultural socialization practices. Implications and conclusions drawn from the themes were identified for transracially adoptive parents, counselors, counselor education programs, and transracial adoption researchers to inform culturally responsive practices when working within the adoption kinship network.
Extracting Dimensions of Interpersonal Interactions and Relationships
Authors:   , Rashid Farzana
Published: February 2025

People interact with each other through natural language to express feelings, thoughts, intentions, instructions etc. These interactions as a result form relationships. Besides names of relationships like siblings, spouse, friends etc., a number of dimensions (e.g. cooperative vs. competitive, temporary vs. enduring, equal vs. hierarchical etc.) can also be used to capture the underlying properties of interpersonal interactions and relationships. More fine-grained descriptors (e.g. angry, rude, nice, supportive etc.) can also be used to indicate the reasons or social-acts behind the dimension cooperative vs. competitive. The way people interact with others may also tell us about their personal traits, which in turn may be indicative of their probable success in their future. The works presented in the dissertation involve creating corpora with fine-grained descriptors of interactions and relationships. We also described experiments and their results that indicated that the processes of identifying the dimensions can be automated.
Exploring the Transnational Meaning of Home Amid Insecure, Hazardous Housing
Authors:   , Fessenden Deborah June
Published: February 2025

This project examines refugees' experiences of insecure housing and perceptions of home in the U.S. Many scholars of migration have focused on the resettlement experiences of refugees, including access to housing, yet refugees' experiences with housing in the U.S. remain largely undocumented. The following analyzes a case study of an apartment fire that displaced 16 refugee families in Dallas, Texas. Based on 18 in-depth interviews with tenants and members of refugee support organizations and non-profits who responded to the fire, this study reconstructs the events surrounding the fire to explore refugees' perceptions of housing conditions in a low-income neighborhood. This case study contributes to research on housing in two important ways. First, insecure housing conditions preceded the fire at Oakland Place and overall perceptions of housing quality varied among respondents. I find that case managers and members of refugee support organizations identify refugees' housing conditions as insecure, yet refugees express positive feelings about their homes, emphasizing community relations over building quality. Additionally, members of refugee support organizations and non-profits blamed the property manager of Oakland Place for insecure conditions experienced by refugees and perceived the manager as a barrier in refugees' lives. Second, I find that understandings of housing insecurity are shaped by meanings of home, which focus on familial and community-based relationships, and a place for survival. These ideas of home are not mutually exclusive, as refugees often defined home in more than one way.
The Role of Combat Exposure, Moral Injury, and Trauma Symptoms in the Lives of Military Families
Authors:   , Raiche Emily
Published: February 2025

The current study used a sample of service members and veterans to explore the association of combat exposure and perceptions of the family system using a moderated mediation model. Combat veterans over the age of 18 with a family of creation (N = 154) completed an online survey through which they were administered a background information questionnaire, the Combat Experiences subscale of the Deployment Risk and Resilience Inventory – 2, the Moral Injury Events Scale, the PTSD Checklist for DSM-5, the Patient Health Questionnaire, the Beck Anxiety Inventory, the McMaster Family Assessment Device, and the Dyadic Adjustment Scale – Revised. Results of six moderated mediation analyses revealed that exposure to potentially morally injurious events (pMIEs) moderated the relationship between (1) combat exposure and couple relationship satisfaction and (2) combat exposure and family functioning, both via PTSS, anxious symptoms, and depressive symptoms. To our knowledge, the empirical models presented in this paper are the first to model the role of pMIEs in SMV literature, and provide a foundation for other models to emerge moving forward. Implications and limitations are discussed.
That Isolation Creeps In: Exploring the Intersection of Public Transit and Mental Health in Dallas County, Texas
Authors:   , Sanderson Brittney
Published: February 2025

The primary goal of the research project was to organize a community needs assessment, which culminated in a report attached in the appendix. Data from sixteen interviews with community leaders involved in mental health promotion throughout Dallas County, Texas was used as the foundation of the professional report. This data revealed several key barriers faced by those with mental illness in their ability to access mental health services in Dallas County. The information gathered prompted further exploration into the intersection between public transit and mental health. Transit became the focus of this work when it came up as simultaneously a barrier to care and mode of prevention in the majority of the interviews. Interestingly, Dallas County has public plans to address transit related disparities; however, their intervention pulls from strategies determined to be ineffectual among the poor and disenfranchised. In this work we explore community needs and the civic culture of Dallas with a specific focus on transportation.
Building Reliable and Cost-Effective Storage Systems for High-Performance Computing Datacenters
Authors:   , Qiao Zhi
Published: February 2025

In this dissertation, I first incorporate declustered redundant array of independent disks (RAID) technology in the existing system by maximizing the aggregated recovery I/O and accelerating post-failure remediation. Our analytical model affirms the accelerated data recovery stage significantly improves storage reliability. Then I present a proactive data protection framework that augments storage availability and reliability. It utilizes the failure prediction methods to efficiently rescue data on drives before failures occur, which significantly reduces the storage downtime and lowers the risk of nested failures. Finally, I investigate how an active storage system enables energy-efficient computing. I explore an emerging storage device named Ethernet drive to offload data-intensive workloads from the host to drives and process the data on drives. It not only minimizes data movement and power usage, but also enhances data availability and storage scalability. In summary, my dissertation research provides intelligence at the drive, storage node, and system levels to tackle the rising reliability challenge in modern HPC datacenters. The results indicate that this novel storage paradigm cost-effectively improves storage scalability, availability, and reliability.
Exploration of RDA-Based MARC21 Subject Metadata in Worldcat Database and Its Readiness to Support Linked Data Functionality
Authors:   , Zavalin Vyacheslav I.
Published: February 2025

Subject of information entity is one of the fundamental concepts in the field of information science. Subject of any document represents its intellectual potential -- 'aboutness' of the document. Traditionally, subject (along with title and author) is the one of three major ways to access information, so subject metadata plays a central role in this process and the role is constantly growing. Previous research concluded that the larger bibliographic database is, the richer subject vocabularies and classification schemes are needed to support information discovery. Further, a high proportion of information objects are unretrievable without subject headings in metadata records. This exploratory study provides the analysis of the subject metadata in MARC 21 bibliographic records created in 2020; and develops understanding of the level and patterns of 'aboutness' representation in the MARC 21 bibliographic records. Study also examines how these records apply the recent RDA and MARC21 guidelines and features intended to support functionality in a Linked Data environment. Methods of Social Network Analysis were applied along with content analysis, to answer research questions of this study. Suggestions for future research, implications for education, and practical recommendations for library metadata creation and management are discussed.
Synthesis, Modification, and Analysis of Silicate Cosmic Dust Analogues Using Ion-Beam Techniques
Authors:   , Young Joshua Michael
Published: February 2025

Silicates analogous to cosmic dust were synthesized, modified, and analyzed utilizing ion-beam techniques with Rutherford backscattering spectrometry (RBS) and x-ray diffraction (XRD). Silicate dust is a common constituent in interstellar space, with an estimated 50% of dust produced in the stellar winds of M class Asymptotic Giant Branch (AGB) stars. Silicate dust acts as a surface upon which other chemicals may form (water ice for example), increasing significance in the cosmochemistry field, as well as laboratory astrophysics. Silicate formation in the stellar winds of AGB stars was simulated in the laboratory environment. Three sequential ion implantations of Fe-, MgH2-, and O- with thermal annealing were used to synthesize a mixture appropriate to silicate dust in the surface layers of a p-type Si substrate. Post implantation He+ irradiation was shown to preferentially induce crystalline formation in the analogue prior to thermal annealing. This effect is believed to originate in the ion-electron interaction in the Si substrate. The effects of ionization and ion energy loss due to electronic stopping forces is believed to precipitate nucleation in the amorphous media. For annealing temperatures of 1273 K, predominant quartz formation was found in the substrate, whereas lower annealing temperatures of 1000 K formed enstatite without post-implantation He+ irradiation, and olivine with He+ irradiation. Post annealed crystalline phase modification was investigated via x-ray diffraction and elemental compositions were investigated utilizing RBS. Finally, the interdiffusion of Fe and Mg at temperatures of 900-1100 K was investigated with RBS, and activation energies for interdiffusion were extracted for the transition from amorphous to crystalline phase in the silicate analogues. Fe had an interdiffusion energy of 1.8 eV and Mg 1.5eV. The produced analogues have similar properties to those inferred from infrared spectroscopy of the stellar winds of M-class AGB stars with an oxygen-rich outflow. This work established a method of silicate production using ion beam modifications, explored He+ irradiation effects in the annealed structures, and derived interdiffusion activation energies for Fe and Mg in the amorphous structure. Grain sizes were <100 nm with the observed formation of quartz, enstatite, and olivine.
Così fan tutte? A Study of Character Development through Key Characteristics in the Prima Donna and Soubrette Roles from Four of W.A. Mozart's Late Italian Operas
Authors:   , Tsai Meng-Jung
Published: February 2025

This dissertation investigates how W. A. Mozart applies the concept of key characteristics—the affective properties of each tonality—as discussed by three of his contemporaries, Johann Mattheson, C.F.D. Schubart and G.J. Vogler, to four soubrette and four prima donna characters from four of his late Italian operas: La Contessa and Susanna in Le nozze di Figaro; Donna Anna and Zerlina in Don Giovanni; Fiordiligi and Despina in Così fan tutte; Vitellia and Servilia in La clemenza di Tito. The analytical method of this dissertation provides a hermeneutical tool to search for meanings in Mozart's music. The application compares the libretto text and its corresponding tonal center with the description of key characteristics on a micro level, to reveal significant dramatic and practical implications from Mozart's key usage in his operas.

The goal of this study was to use a nonlinear approach to create a program to teach positive and negative reinforcement and punishment. A specific interest was to determine whether the program and its testing allowed for specific recommendations for future iterations of the program. The tests and program developed for this study were completed by 18 participants. Pre-test and post-test data showed that participants learned the most about positive contingencies, nonexample items, and ambiguous contingencies. Participants learned the least about negative contingencies. The data also revealed where additions to the instructional program were needed to produce better outcomes in future versions of the program.
The Relationship between Social Isolation and Wellbeing in Older Adults
Authors:   , Sen Keya
Published: February 2025

This dissertation contributes to research on social isolation in older adults aged 65 years and above through three essays that expand our understanding of the social determinants of health and identify the social and interpersonal factors that contribute to elderly wellbeing. This dissertation examines the significant factors contributing to the problem of social isolation, and how the availability of interest-based, low-cost engagement resources in the community can alleviate social isolation and foster healthy aging. Essay 1 is a systematic literature review with implications for future research that explores how technological skills and training based on user intention and availability of resources can alleviate social isolation. Essay 2 is a qualitative study that evaluates the effectiveness of a unique community-based senior exercise program in fostering social integration and in reducing social isolation. Essay 3 is a quantitative study that examines the magnitude and direction of the correlated relationships among the determinants of social inclusion and the impact of social and interpersonal processes on senior wellbeing. These three essays provide insight into the social isolation phenomenon that negatively impacts senior wellbeing and recommends solutions derived from a data driven examination of the problem that is especially applicable to economically disadvantaged senior communities. Moreover, this research provides community partners and gatekeepers a foundation for future research on the social isolation phenomenon and strategies for developing digital confidence and mobility program strategies that foster social inclusion and reduce social isolation for older adults.
Crisis, New Imperialisms, and Accumulation by Dispossession: The Case of the Pakistan Railways
Authors:   , Khan Sher Ali
Published: February 2025

My research examines the three interrelated concepts of crisis; new imperialisms, spatial-temporal fix and accumulation by dispossession (ABD) stemming from the work of David Harvey as a way to understand the contested history of the Pakistan Railways. For the first thirty odd years after Pakistan's inception in 1947, the railways, a state-owned institution, was the primary mode of transport for the public, cargo, and workers. Alongside basic infrastructure, the railways had a vast network of hospitals, schools, workers' colonies and an array of physical infrastructure connected to production, operations and other aspects of the economy. The systematic ransack and decline of the Pakistan Railways reached its peak in 2010. Despite several attempts throughout the 1990s by successive democratic and military-led governments backed by the IMF/World Bank in 2015, it was announced that Pakistan railways would be revived under the banner of the 46 billion dollar China Pakistan Economic Corridor (CPEC) as part of the changing geopolitical context of growing regional connectivity and new Chinese imperialism. By examining the processes that underlie ABD, such as spatial-temporal fix, the following research shows that these processes not only reflect a shift of resources away from the public domain, but in Pakistan also entailed the transformation of the railways from a utilitarian welfare organization to an entity that facilitates looting, unbundling, and dispossession of shared resources and infrastructure.
Passive Control of Fiber Orientation in Direct Ink Writing 3D Printing
Authors:   , Khatri Nava Raj
Published: February 2025

Several active methods, which requires external control systems and moving parts, have been developed to control the fiber orientation during 3D printing. Active mechanisms like rotating nozzle, impeller, and magnetic field have been integrated to realize complex internal fiber structures. In this study, instead of using active methods, I investigate a passive method for controlling the fiber orientation without any moving parts or additional mechatronics added in the printing process. Composites of polydimethylsiloxane (PDMS) and glass fibers (GF) are 3D printed. Channels, such as helicoid, are designed and integrated to guide the ink flow and passively result in different pre-alignment of fibers before the ink flow into narrow nozzle space. While passing through the designed channels, the fibers orient due to the shear between channel walls and the ink. The effect of helicoids with different pitch sizes are investigated via mechanical experiments, microstructural analysis, and numerical simulations. The results show that both surface to volume ratio and helix angle of the channel affect pre-alignment of fiber orientation at the entry of nozzle. The internal fiber structures lead to enhanced and tunable mechanical properties of printed composites. Pitch size 7-9 mm (helix angle of 7.92- 10.15o) is found to be optimal for the 3D printed PDMS-GF composites. Stiffness and strength can be tuned up to 77.6% and 47.8%, respectively, compared with the case without helicoid channel. Channels of parallel holes, parallel holes with taper end and gradually changing pitch helicoids are experimentally tested, showing further enhancement in mechanical properties.

Understanding the Health Needs among Indigenous Mayan Communities of Lake Atitlan
Authors:   , Koyuncuoglu Leyla Maria
Published: February 2025

Considering the changes the Lake Atitlan, Guatemala region has undergone in the last several years, ODIM (Organization for the Development of the Indigenous Maya) seeks to understand the needs of the San Juan La Laguna and San Pablo La Laguna communities, and to provide competent, culturally-aligned care that is affordable to the Indigenous Maya of this region. Using mixed-methods approaches that incorporate interviews, surveys, graphic anthropology, and evaluation methods, this study investigated (1) the formal and informal health care services (including those offered by ODIM) and how and why they are utilized by local Guatemalans, (2) Guatemalan perceptions and experiences of health, wellbeing, and illness to understand how they might influence health related behavior, and (3) community health care needs and how ODIM can fill those needs. These objectives served to inform key stakeholders of current gaps in healthcare services, provide feedback regarding the ODIM health services and programs, and provide insight into the current health needs in order to ameliorate the burden of disease and illness around Lake Atitlan, Guatemala. This study produced a comprehensive community health profile, and it discusses the current state of health care, explains the local perspectives of health care, and gives direct feedback and recommendations to ODIM's community health programs.
Multifactorial Determinants of Change in Mental Disorder and Happiness among Older Americans
Authors:   , Adaralegbe Adeleye Ayinde
Published: February 2025

Mental health is an intrinsic capability that constitute an essential component of healthy aging. Mental health is constituted by positive constructs such as happiness and negative constructs (mental disorders) such as depression. As people grow older, they become more prone to developing mental disorders which are linked to poorer quality of life, increased disability, increased utilization and cost of health services, and higher rates of suicide. This dissertation involved three studies that focused on factors that predict change in mental disorders and happiness of older Americans over a period of five years. Two waves of publicly available national representative data from the National Social Life Health and Aging Project (NSHAP) collected in 2010 and 2015 were used. A total of 2210 older adults within the ages 62-90 years were used in the analyses. Mental health measures were CES-Depression scale, HADS anxiety scale, and self-rated happiness. Essay 1 aimed to identify the important aspects of older adults' interaction with their neighborhood that predict the presence of mental disorder and happiness. Essay 2 evaluated the psychosocial factors that predict change in mental disorder and happiness of older adults, whereas essay 3 investigated the multifactorial determinants of change in mental disorder and happiness of older adults. These three essays provide insight into the impact of mental health in old age and the role of environmental, social, and demographic factors in successful aging. It also provides gaps for future research in the field of mental health and aging.
Radial and Axial Designs for Magnetic Absorbent Collector in Water
Authors:   , Renzetti Andrew John
Published: February 2025

The use of collection systems for magnetic sorbents such as Magnetic Activated Carbon are discussed in order to gauge their efficacy in marine environments. Two collectors were built and tested, one which utilized a radial orientation of magnets and another with axially placed magnets. The two systems underwent a series of test with differing linear velocities and angular velocities. From the results, the axial system outperformed its radial counterpart, being most effective with a relatively high concentration of discs placed in series. The medium concentration, however, proved increasingly effective with higher velocities, meaning an optimization concentration exists for this design. The radial system was tested with high and low concentrations of small and large magnets, respectively. The larger magnets, although providing less concentration points in the alternating array, proved more effective for the collection of MAC. From these tests several new innovations were suggested, including belt tensioners, add on mechanisms, and a hybridized design in order to fully optimize the collection of MAC.

Design Method for Cold-Formed Steel Shear Wall Sheathed with Polymer Composite Panel
Authors:   , Dewaidi Mohaned Ali
Published: February 2025

In order to predict the strength of shear wall with cold-formed steel framing members, analytical models were reviewed. Multiple analytical models were studied, as well as twenty-one connection tests were performed. The connection tests consist of 50-ksi cold-formed steel framing track, different fastening configurations, and different sheathing thicknesses (1/8" and 1/2"). No.12 screw resulted in the highest peak load of all fastening configurations, while the rivet connection had the lowest peak load. In addition, failure modes were observed after conducting the connection tests including shear in fastening, screw pullout, and bearing in the sheathing. However, only the rivet and No.10 screw fastening configurations were used in the prediction analysis of the shear wall by the elastic model. Six shear wall tests were conducted on both panels (1/2"and 1/8" thickness). After doing the comparison between the experimental and the elastic model, the percentage difference for the 1/8" and the 1/2" polymer composite panels (3''along the edge and 6''along the chord stud), was very small. It was 6.2% for the 1/8" and 2.96% for the 1/2" panels. This means the analytical model can predict the shear wall peak load. However, the percentage difference was slightly higher being 7.4% for the 1/2" polymer composite panels with 6" along the perimeter with the 12" at the chord stud. After comparing the experimental values to the predicted value of shear walls, it was concluded that this model is the most appropriate analytical method for predicting the shear wall capacity framed with cold-formed steel sheathed with polymer composite panels. Many of these configurations were used in a prototype shelter that was constructed and built at the structural testing laboratory at the University of North Texas.
Cooperative Perception for Connected Autonomous Vehicle Edge Computing System
Authors:   , Chen Qi
Published: February 2025

This dissertation first conducts a study on raw-data level cooperative perception for enhancing the detection ability of self-driving systems for connected autonomous vehicles (CAVs). A LiDAR (Light Detection and Ranging sensor) point cloud-based 3D object detection method is deployed to enhance detection performance by expanding the effective sensing area, capturing critical information in multiple scenarios and improving detection accuracy. In addition, a point cloud feature based cooperative perception framework is proposed on edge computing system for CAVs. This dissertation also uses the features' intrinsically small size to achieve real-time edge computing, without running the risk of congesting the network. In order to distinguish small sized objects such as pedestrian and cyclist in 3D data, an end-to-end multi-sensor fusion model is developed to implement 3D object detection from multi-sensor data. Experiments show that by solving multiple perception on camera and LiDAR jointly, the detection model can leverage the advantages from high resolution image and physical world LiDAR mapping data, which leads the KITTI benchmark on 3D object detection. At last, an application of cooperative perception is deployed on edge to heal the live map for autonomous vehicles. Through 3D reconstruction and multi-sensor fusion detection, experiments on real-world dataset demonstrate that a high definition (HD) map on edge can afford well sensed local data for navigation to CAVs.
School Board Presidents' Perception of Their Role and Its Relationship to Effective Board Practices
Authors:   , Herron Angela Abney
Published: February 2025

The purpose of this study was threefold: (a) to identify the priorities that Texas school board presidents perceive to be most important in their role as a school board member; (b) to describe the specific activities, behaviors, and actions that Texas school board presidents say they take to support the priorities they identify; and (c) to compare with and contrast board members' reported priorities, activities, behaviors, and actions with the eight characteristics of effective school board practices. A mixed-methods research design was used to explore school board presidents' perceptions of their role and its relationship to effective board practices. Quantitative data were gathered using an online survey and analyzed using descriptive statistics. Qualitative data were obtained from one-on-one semi-structured interviews which were manually coded using a three-step, hybrid-coding process, as well as from an observation protocol. Evidence from this study identified four top priorities: accountability driven actions, a untied team with the superintendent, aligned and sustained resources, and a vision of high expectations. Eleven subthemes emerged that describe the activities, behaviors, and beliefs that support these priorities including: clear goals, community partnerships, data-driven informed, governance, human capital, policy adoption, professional development, strong communication, student outcomes, training, and trust.
Effectiveness of the SASSI-4 in Classifying Substance Use Disorders and Detecting Response Styles
Authors:   , Hartigan Sara E
Published: February 2025

The current study explored the effects of simulated adjustment domains (i.e., partial denial and social desirability) on specialized substance abuse measures in a sample of 104 inpatient offenders with substance use disorders. Results indicated nearly two thirds (57.9%) of offenders successfully escaped detection on the SASSI-4 and InDUC-2R. Further, subtle approaches employed by the SASSI-4 failed to detect unacknowledged substance use by simulators, and the remaining decision rules were redundant and most likely contributed to the false positive rates for non SU offenders. More promisingly, the current study developed an empirically based validity scale to bolster the SASSI-4's effectiveness in detecting response styles that showed initial promise. Results, a review of detection strategies for SU validity scales, and implications for assessment are further explored.
Interstate Influence Strategies in Border Crises: 1918-2015
Authors:   , Yao Jiong
Published: February 2025

Within interstate militarized disputes, states use different kinds of influence strategies, like bullying, reciprocating, and trial-and-error. My dissertation examines state influence strategies within border disputes. This context serves as a hard test which could testify if state behaviors in world politics are mainly driven by the salience of contested issues. Or other factors, like leader militarized backgrounds (e.g., participating in rebellions or military service), may also at work. On the other hand, focusing on state influence strategies could be a promising direction to investigate the dynamics of border disputes, like border crisis outcomes. My dissertation contains three chapters. The first chapter explores the rationales behind state choices of influence strategies in border crises by focusing on leaders and their militarized experiences. The second chapter focuses on the influence strategy's short-term effect by examining how do hey influence border crisis outcomes? The third chapter examines the influence strategy's long-term impact by investigating how do they affect the durability of border claims? My dissertation has some important findings. First, leader militarized backgrounds influence state choices of influence strategies. Second, bullying strategies create escalations, which make border crises more likely to end in stalemate or decisive outcomes. By contrast, both reciprocating and trial-and-error ease the tension and make border crises more likely to end in compromises. Third, in the long term, the bullying strategies enable states to learn the costs of territorial fights, who then are willing to drop territorial claims. Neither reciprocating or trial-and-error strategies has this effect.

How is the Volatility Priced by the Stock Market?
Authors:   , Yu Huaibing
Published: February 2025

Traditional portfolio theory suggests that, in equilibrium, only the market risk is priced in the cross-section of expected stock returns. However, if the market is not perfect and investors are constantly changing investing behaviors based on their perceptions about future market outlook, then non-traditional risk factors could potentially provide significant power of describing the expected stock returns. This dissertation has two essays on the pricing of volatility, in which the market is not assumed to be frictionless or perfect. Essay 1 focuses on the pricing of individual volatility in penny stocks. Empirical results show that individual volatility plays an important role in describing the average cross-sectional returns of penny stocks. Resorting to the rolling portfolio approach, evidences indicate that portfolios consisting of penny stocks with high individual volatilities, on average, earned much higher returns than portfolios consisting of penny stocks with low individual volatilities. This effect is statistically significant when multiple factors are controlled simultaneously. Essay 2 focuses on the pricing of the market volatility among individual stocks. Following the rolling portfolio method, Essay 2 constructs portfolios that consist of individual stocks with various market volatility exposures. Traditional risk factors such as market beta, size, book-to-market, and momentum are controlled respectively to obtain more detailed analyses. Empirical results yield a negative pricing of the market volatility and it is more prominent in stocks that have high market beta, small size, and high book-to-market.

This study applied social disruption as a concept that highlights factors responsible for the breakdown of social relationships in societies. Social disruption has many forms, however, the focus in this study was on strikes, which create constant social disruption in Nigerian public universities and could have serious impact on students' information behavior. Two universities – Federal University of Technology Owerri (FUTO) and Imo State University Owerri (IMSU) – were chosen for the study, and data was obtained through an online survey across sample of approximately 250 participants from the two selected public universities in Nigeria. The study applied the principle of least effort theory and the model of information search process to investigate the research questions of this dissertation which were: (1) what kinds of information do university students in Nigeria seek, and to what extent do strikes have implications on their information behavior?; (2) how do Nigerian students perceive the impact of strikes on their information source location and information resource usage?; (3) to what extent can information and communication technology (ICT) minimize the impact of strikes on students' information behavior?; and (4) how can universities in Nigeria prevent strikes from impacting students' information behavior? t-Tests were applied to test the hypotheses. Findings suggested that strikes negatively impacted students information behavior in certain areas of information needs, information use and information sources.
