The Effects of a Contingent S-Delta
Authors:   , Ochoa Jules
Published: January 2025

This thesis attempted a cross-species replication of Bland, et. al., 2018. Human participants went through a computerized, automated shaping procedure that trained them to click on and discriminate between a blue square (SD) and red square (S-delta) on a VR 12 schedule of reinforcement. Three conditions were then presented to the participants consisting of a baseline, punishment, and control condition. In the punishment and control conditions, the SD was replaced by the S-delta or a novel stimulus respectively for 1-second on a VR 5 schedule. With each click, the reaction time and specific object clicked on were recorded. While the present study partially replicated the effect seen in earlier research, our results suggest that, depending on the lens of analysis used, either a punishment or an extinction effect may be causing the results seen.
GIS-Based Analysis of Local Climate Zones in Denton, Texas
Authors:   , Michel Daniel
Published: January 2025

This study implemented a GIS-based analysis of local climate zones (LCZ) in Denton, TX with data sets from 2009, 2011, 2015, and 2016. The LCZ scheme enables evaluation of distinct regions' thermal characteristics with greater granularity than conventional urban-rural dichotomies. Further, the GIS-based approach to LCZ mapping allows use of high-resolution lidar data, the availability of which for the study area enabled estimation of geometric and surface cover parameters: height of roughness elements, sky-view factor, and building surface fraction. Pervious surface fraction was estimated from National Landcover Database impervious imagery. A regular grid was used to estimate per-cell mean values for each parameter, and with a decision-making algorithm (if/then statements) two maps were produced (2011 and 2015) and six LCZ identified in each: LCZ 6 (open low-rise), LCZ 8 (large low-rise), LCZ 9 (sparsely built), LCZ A (dense trees), LCZ B (scattered trees), and LCZ C (bush/scrub). Post-processing was carried out to ensure identified zones met the spatial minimum for qualification as LCZ. Landsat Collection 2 Level 2 surface temperature products from various seasons of 2011 and 2015 were acquired to examine LCZ thermal differentiability, and preliminary surface urban heat island intensity values were estimated. Particular attention was afforded to issues regarding data quality and classifier threshold adjustment.
Perceptions of Charter School Administrators and Teachers about Factors Accounting for Academic Effectiveness
Authors:   , Hunter Adrienne M
Published: January 2025

This qualitative case study examines academic performance effectiveness (or lack of effectiveness) of a charter school based on the perceptions of the administrator and teachers. This study explores what they perceived to be effective/ineffective, the reasons for this effectiveness/ineffectiveness, and the solutions to any identified challenges/problems at their charter school as they relate to students' academic performance. The participants in the study were from one charter school in a charter school system in North Central Texas. The study utilized surveys and interviews as sources of data that revealed administrator and teacher perception of what they considered to be the strengths and weaknesses of the school, factors accounting for the strengths and weaknesses, and possible solutions to the weaknesses of their charter school as related to students' academic performance. Five perceived strengths were identified to be instruction, curriculum, personnel, mission statement, and parent involvement. Likewise, three perceived weaknesses were identified to be instruction, curriculum, and parent involvement. Recommendations of the study for practitioners included recruitment and employment of preservice teachers from colleges and universities, partnering with alternative certification programs, creating a program of professional development, creating professional learning communities, creating a parent committee, and partnering with local agencies and community businesses. Implications for future research included similar analysis of schools within the same charter school system, analysis of a charter school within another charter school district and replicating this study with the addition of parents.
Effectiveness of Treatment-as-Usual among Children with Autism Spectrum Disorder (ASD)
Authors:   , Gordon Amanda McKinley
Published: January 2025

Autism spectrum disorder (ASD) presents with difficulties in social communication, repetitive and/or restricted behaviors, as well as variable language development. Individuals with suspected ASD ideally participate in assessments which include measures of cognitive abilities, adaptive functioning, language functioning, and ASD specific measures (i.e., ADOS, ADI-R). Diagnosis of ASD can occur confidently at 2 years of age, however, the mean age at diagnosis is 4-5 years old. Delays in diagnosis are accounted for by lacking professionals and centers with the capabilities to assess ASD, as well as long waitlists for assessments. Early identification and intervention have been shown to provide the best improvements in ASD symptomology. The aim of the current study was to conduct a program evaluation of an autism treatment center that was designed to provide high quality evidence-based interventions. The study determined if treatment-as-usual in that center yields the expected gains in adaptive functioning and corresponding decreases in barriers to learning. Results indicated improvement in scores on standardized direct assessment of milestone achievement and barriers to learning, but no significant improvement in adaptive skills via secondary informant questionnaire measures following 6 months of treatment. The overall sample size was small due to COVID-19 complications, lack of institutional procedures, and limited client pool. Further investigation into the treatment practices and reevaluation strategies for individuals with ASD is required.
Integrating Multiple Deep Learning Models to Classify Disaster Scene Videos
Authors:   , Li Yuan
Published: January 2025

Recently, disaster scene description and indexing challenges attract the attention of researchers. In this dissertation, we solve a disaster-related multi-labeling task using a newly developed Low Altitude Disaster Imagery dataset. In the first task, we realize video content by selecting a set of summary key frames to represent the video sequence. Through inter-frame differences, the key frames are generated. The key frame extraction of disaster-related video clips is a powerful tool that can efficiently convert video data into image-level data, reduce the requirements for the extraction environment and improve the applicable environment. In the second, we propose a novel application of using deep learning methods on low altitude disaster video feature recognition. Supervised learning-based deep-learning approaches are effective in disaster-related features recognition via foreground object detection and background classification. Performed dataset validation, our model generalized well and improved performance by optimizing the YOLOv3 model and combining it with Resnet50. The comprehensive models showed more efficient and effective than those in prior published works. In the third task, we optimize the whole scene labeling classification by pruning the lightweight model MobileNetV3, which shows superior generalizability and can disaster features recognition from a disaster-related dataset be accomplished efficiently to assist disaster recovery.
Instrumental Development and Implementation of Portable Membrane Inlet Mass Spectrometry for Homeland Security and Environmental Applications
Authors:   , Anguiano Virgen Camila
Published: January 2025

A rapidly growing topic of great interest is the adaptation of benchtop analytical instrumentation for use in outdoor harsh environments. Some of the areas that stand to benefit from field instrumentation development include government agencies involved with the preservation of the environment and institutions responsible for the safety of the general public. Detection systems are at the forefront of the miniaturization movement as the interest in analyte identification and quantitation appears to only be accessible through the use of analytical instrumentation. Mass spectrometry is a distinguished analytical technique known for its ability to detect the mass-to-charge (m/z) ratios of gas-phase ions of interest. Although these systems have been routinely limited to research lab-based analysis, there has been considerable development of miniaturized and portable mass spectrometry systems. Membrane Inlet Mass Spectrometry (MIMS) is becoming a common method of sample introduction that is subject to significant development. MIMS allows for minimal sample preparation, continuous sampling, and excludes complicated analyte introduction techniques. Sampling is accomplished using a semipermeable membrane that allows selective analyte passage into the vacuum of the mass spectrometer. MIMS is becoming the preeminent choice of homeland security and environmental monitoring applications with increasing opportunities for the future development of specialized systems. The steadfast development of miniaturized mass spectrometry systems with efficient operation capabilities for a variety of applications gives promise to the further development of MIMS technology as well as other analytical instrumentation.
Modeling Email Phishing Attacks
Authors:   , Almoqbil Abdullah
Published: January 2025

Cheating, beguiling, and misleading information exist all around us; understanding deception and its consequences is crucial in our information environment. This study investigates deception in phishing emails that successfully bypassed Microsoft 365 filtering system. We devised a model that explains why some people are deceived and how targeted individuals and organizations can prevent or counter attacks. The theoretical framework used in this study is Anderson's functional ontology construction (FOC). The methodology involves quantitative and qualitative descriptive design, where the data source is the set of phishing emails archived from a Tier 1 University. We looked for term frequency-inverse document frequency (Tf-idf) and the distribution of words over documents (topic modeling) and found the subjects of phishing emails that targeted educational organizations are related to finances, jobs, and technologies. Also, our analysis shows the phishing emails in the dataset come under six categories; reward, urgency, curiosity, fear, job, and entertainment. Results indicate that staff and students were primarily targeted, and a list of the most used verbs for deception was compiled. We uncovered the stimuli being used by scammers and types of reinforcements used to misinform the target to ensure successful trapping via phishing emails. We identified how scammers pick their targets and how they tailor and systematically orchestrate individual attack on targets. The limitations of this study pertain to the sample size and the collection method. Future work will focus on implementing the derived model into software that can perform deception identification, target alerting and protection against advanced email phishing.
The Effect of Online Consumer Reviews and Brand Equity on the Consumer Decision Making Process
Authors:   , Ahmad Fayez
Published: January 2025

This research aims to investigate the (1) review effects on consumer decision making process, (2) effects of negative reviews on brand equity, and (3) consumers' likely response to a brand's request for reviews. The objective of the first essay is to investigate the nature of the relationship between skepticism and consumer decision making in an online behavior context. Its second objective is to know whether people's belief on their abilities or their hedonic principle moderates the relationship between a person's skepticism toward online reviews and their reliance on online reviews. The objective of the second essay is to explore whether negative online reviews that focus on service quality specific dimensions have a different effect on a service organization's perceived brand equity. Its second objective is to analyze the role of emotional contagion in the relationship between negative reviews related to various service quality dimensions and its effect on perceived brand equity. The main objective of the third essay is to know whether consumers are more likely to write an online review for a brand when the request comes from a higher equity brand. This essay also investigates how message trust and persuasion knowledge influence the relationship between a brand's request to write online reviews and the likelihood of consumers to write reviews. These three essays altogether contribute to the online review and the brand equity literature by providing new insights about the intricate relationship between online reviews, brand equity, and consumer decision-making.
Understanding the RCS Way: A Study of Organizational Culture
Authors:   , Terry Vanessa S.
Published: January 2025

The quality of workplace morale can positively and negatively affect employee engagement. Engaged employees are more likely to participate in active communication with one another. They are also more likely to adopt the organizational goals and work towards creating a productive work environment. Communication and engagement build trust. Established trust between employees and executive leadership is a delicate relationship to maintain, though it is necessary when contending with periods of stress. The organization profiled below experienced the stressor of needing to grow without alienating those afraid of change or used to operating in one predictable direction. There was a desire to generate engagement, build trust and make room for employee-directed change. This desire left the organization open to exploring its culture and its impact on employee engagement.
Analyzing the Principal Perspective to Lead the Implementation of Learning Technologies in Public Schools: A Multi-Strategy Study
Authors:   , Orta Nelson A
Published: January 2025

As technologies for learning become increasingly available in K-12 schools, the role and responsibilities of campus principals continue to evolve. Incorporating technologies in schools requires shifts in practices, the development of new skills, and in some cases, changes in the mindset of stakeholders. Schools should be capable of absorbing the knowledge and creating the systemic structures required for the implementation ICTs. The purpose of this study was to research the principals' perspective to lead the implementation of ICTs for learning in public schools. As campus leaders, principals are increasingly required to support the utilization of ICTs for classroom instruction. It is of particular importance, therefore, to study and explore the needs school principals identify to lead the implementation of technologies for learning. More specifically, the goal was to gather relevant data to analyze topics that campus principals believe positively and negatively influence the implementation of ICTs in schools.
An Information Theoretic Analysis of Multimodal Readability
Authors:   , Hovious Amanda S.
Published: January 2025

Educators often inquire about the readability of books and other documents used in the classroom, with the idea that readability supports students' reading comprehension and growth. Documents used in classrooms tend to be language-based, so readability metrics have long focused on the complexity of language. However, such metrics are unsuitable for multimodal documents because these types of documents also use non-language modes of communication. This is problematic because multimodal reading is increasingly recognized as a 21st-century skill. One information theoretic solution is transinformation analysis, an approach that measures readability as the difference between the objective entropy of a document and the subjective entropy of its reader. Higher transinformation indicates more information complexity. This study explored the viability of transinformation analysis as a measure of multimodal readability. Think aloud screen recordings from 15 eighth grade "advanced readers" of Episode 2 of the born-digital novel, Inanimate Alice served as the dataset. Findings showed that 14 of the readers attended to less than half the information in the story. Mean readability was .57, indicating a complex reading experience. Readers attended to and recalled information primarily from the linguistic mode, which may have been a strategy for reducing cognitive load, or it may have reflected beliefs that reading is a language-based activity. The strong traditional readers in this study appeared to be weak at multimodal reading. In addition to its theoretical and methodological implications, the study's findings have implications for the practical need to create more opportunities for multimodal reading experiences in contemporary classrooms and libraries.
Forging Pathways: A Multi-Case Study of Individuals with Intellectual Disability Pursuing Postsecondary Education at the Community College
Authors:   , Jackson Amanda O.
Published: January 2025

This multi-case study sought to better understand how students with intellectual disability (ID) are forging pathways to higher education via the community college. Five individuals with ID who accessed higher education via the community college and their parents/guardians were interviewed. Each case provided insight into personal pathways with results given in case descriptions and individual case themes. Cross-case analysis revealed four themes positively impacting the college-going pathway for students with ID: value-driven grit, pathway knowledge, community support, and accessibility. Based on findings from this study, families appear to be the primary systems forging pathways to the community college for individuals with ID. Local education agencies and community colleges can assist these families by engaging in interagency collaboration, evaluating their systems, and aligning practices to the goal of students with ID accessing and engaging in higher education.
Putting the Pieces Together: Using Learning Analytics to Inform Learning Theory, Design, Activities, and Outcomes in Higher Education
Authors:   , Goodman Amy Graham
Published: January 2025

The goal of learning analytics is to optimize learning and the environments in which it occurs. Since 2011, when learning analytics was defined as a separate and distinct area of academic inquiry, the literature has identified a need for research that presents evidence of effective learning analytics, as well as, learning analytics research that is conducted in conjunction with learning theory. This study uses Efklides' metacognitive and affective model of self-regulated learning (MASRL) to define cognitive, metacognitive, and affective variables that can explain students' learning outcomes in hybrid/online sections of Calculus I in the 2020-21 academic year. Cognitive variables were measured according to the cognitive operational framework for analytics (COPA). Metacognitive variables were defined according to the ways in which students interacted with the course content in the learning management system (LMS) and supplemental instruction, and affective variables were measured by ways students gave evidence of their affective states, such as in discussion board posts. All variables were compared across the course learning design, activities, and outcomes. Binary logistic regression revealed five significant variables: two cognitive, one metacognitive, and two affective. Thus, this study provided a learning analytics, evidence-based link between self-regulated learning theory and learning design, activities, and outcomes. In addition, implications for students, instructors, and learning theory were explored, as well as, the qualifications of this study as evidence of effective learning analytics.
Towards Increased Precision of the 4He:23P1→23P2 Transition Measurement Using Laser Spectroscopy
Authors:   , Cameron Garnet
Published: January 2025

Significant sub-systems were created and others enhanced providing a platform for an order of magnitude precision increase of the small 4He interval - 23P1→23P2 laser spectroscopy measurement, as well as other helium transitions. These measurements serve as tests of helium theory and quantum electro-dynamics in general. Many improvements to the original experiment are discussed and characterized. In particular, counting speed increased 10x, the signal level was doubled, a novel Doppler shift minimization technique was implemented, a control node re-architecture was realized along with many useful features, and the development environment was updated. An initial 28% precision improvement was achieved also providing a foundation for additional gain via a created smaller and more heavily windowed vacuum cavity and picomotor controls.
Understanding the Knowledge, Skills, and Abilities (KSAs) of Data Professionals in United States Academic Libraries
Authors:   , Khan Hammad Rauf
Published: January 2025

This study applies the knowledge, skills, and abilities (KSA) framework for eScience professionals to data service positions in academic libraries. Understanding the KSAs needed to provide data services is of crucial concern. The current study looks at KSAs of data professionals working in the United States academic libraries. An exploratory sequential mixed method design was adopted to discover the KSAs. The study was divided into two phases, a qualitative content analysis of 260 job advertisements for data professionals for Phase 1, and distribution of a self-administered online survey to data professionals working in academic libraries research data services (RDS) for Phase 2. The discovery of the KSAs from the content analysis of 260 job ads and the survey results from 167 data professionals were analyzed separately, and then Spearman rank order correlation was conducted in order to triangulate the data and compare results. The results from the study provide evidence on what hiring managers seek through job advertisements in terms of KSAs and which KSAs data professionals find to be important for working in RDS. The Spearman rank order correlation found strong agreement between job advertisement KSAs and data professionals perceptions of the KSAs.
Exploring the Complex Exchange Relationships in Direct Selling Channels
Authors:   , Geng Guanyu
Published: January 2025

This dissertation research explores the factors that influence direct selling agents' sales performance and job satisfaction. In the direct selling channels, the agents not only sell the products to customers. They may concurrently perform a "distributor" role as a stand-alone entity composed of their own sales network. This dissertation research features two essays. The first essay investigates how direct selling agents' perceptions of control and sense of belonging relate to PO. This essay further explores how PO influences job performance and job satisfaction. Results suggest that perception of control and sense of belonging fuel PO. Furthermore, leader-member exchange mediates the relationship between PO and sales performance, as well as PO and job satisfaction in direct selling networks. The second essay introduces a new construct (relational incongruity) and discusses how complex sales environments and direct selling agents' organizational structures influence the relational incongruity in their organization and its ensuring effect on sales performance and job satisfaction. The results indicate that organizational complexity is positively related to relational incongruity. However, customer complexity has a negative impact on relational incongruity. Relational incongruity in direct selling agents' organizations has negative effects on job satisfaction but has no effects on sales performance. Epistemic curiosity undermines the negative effect of relational incongruity on job satisfaction but negatively influences independent distributors' sales performance.
PubMed Commons: What Happened on the Way to the Forum? Retrospective Explanatory Case Study Research and Lessons Learned from the U.S. National Library of Medicine's Online Forum for Open Science
Authors:   , Farabough Michelle Claire
Published: January 2025

The U.S. National Library of Medicine brought the intensifying interest in open science to national attention when it joined enthusiastic scientists to introduce and host an Amazon-like rating forum on PubMed—the world's largest database of indexed biomedical and life sciences literature. The result was PubMed Commons. In June 2013, the commenting forum was introduced for open discussion about published scientific literature as part of a three-pronged approach to improve research rigor, reproducibility, and transparency. In Feb. 2018, the forum was unexpectedly discontinued. This retrospective explanatory case study research asked the question, "What happened on the way to the forum?" Answers came from a variety of resources using multiple methodologies for data collection and analysis. Historical data from PubMed Commons' 7,629 comments and 1,551 commenters; key informant interviews with PubMed Commons editors; and a systematized search for published articles, gray literature; and social media content about PubMed Commons were analyzed using computer-mediated discourse analysis and a social network analysis. Results from the quantitative content analysis described a forum with little participation, and the qualitative content analysis demonstrated that active forum members were focused primarily on providing links to other information resources and discussing aspects of post-publication peer review. The social network analysis revealed a disconnected network, which was supported by a sociogram showing a community of independents with only seven small clusters. Findings pointed to 11 factors that affected the forum's adoption and use. Rogers' diffusion of innovation theory scaffolds a forum innovation agility model developed from this work to offer a better understanding of organizational processes and to aid organizations interested in introducing and managing a similar forum. PubMed Commons was a missed opportunity. No comparable alternative is available to promote open science and serve as a tool for the expected paradigm shift in the way we do scholarly communication in science.
Nontraditional Six-Four Chords and Their Impact on Middleground Structures in Schumann, Brahms, and Saint-Säens
Authors:   , Gao Yiyi
Published: January 2025

This dissertation explores middleground functionality of six-four chords by combining a voice-leading approach with hypermetrical analysis. By acknowledging the functional ambiguity of certain six-four chords that do not fit into traditional classifications (Aldwell and Schachter's cadential, consonant, passing, and neighboring six-four), or that can be seen as fitting in more than one category, I show that our interpretation of deeper-level structures is contingent upon how we choose to hear the functionality of these harmonies. Three types of six-four chords are introduced: cadential/consonant, passing/cadential, and neighboring/consonant six-four, illustrated by works by Robert Schumann, Brahms, and Saint-Säens. Each pair refers to an ambiguity—the same chord invites two alternative harmonic interpretations. I call these chords nontraditional in the sense that they shed more light on the musical structure with their ambiguity, rather than when being wedged into a single type of a six-four chord. This approach renews the ways of hearing the malleability of nonconventional Romantic structures and permits us to trace the path of each work as a unique tonal trajectory from a listener's perspective.
Linearly-Annulated, Functionalized, β,β'-π-Extended Porphyrins
Authors:   , Moss Austen Edmond
Published: January 2025

Benzannulation to porphyrin 2,3 positions has previously been accomplished using various methodologies in the past century, yet there remain limited methodologies to both annulate to the porphyrin periphery and add functional moieties that can then be derivatized for diverse applications. This dissertation describes the development of synthetic routes and characterization of a variety of linearly-annulated, functionalized, β,β'-π-extended porphyrins. There are five chapters in this dissertation, the first of which introduces synthesis and properties of porphyrins and π-extended porphyrins. Chapter 2 describes synthesis of pentacenequinone-fused and pentacene-fused poprhyrins with distinct and new optical absorbance properties. In chapter 3, synthesis and characterization of benzimidazole-fused porphyrins displaying external metal binding capability is described. The synthetic method developed in chapter 3 is extended in chapter 4 to synthesis of bisbenzimidazole-fused porphyrin dimers that show split Soret character, likely due to excitonic coupling between porphyrins of the dimer. Chapter 5 summarizes this dissertation and describes future directions that this dissertation provides foundation for.
Principal Professional Development for Building Leadership Capacity
Authors:   , Tran Tramy Nguyen
Published: January 2025

The findings of this study serve as an exploratory case-study examining the conditions of professional learning for in-service principals in one north Texas suburban district with changing student demographics. Quantitative and qualitative analysis of a variety of data collected sought to reveal how professional development of principals increased a principal's contingent leadership skills to positively affect student achievement through school improvement efforts. Perceptions were examined from the sample of seven executive directors at the district level; six campus principals (two elementary, two middle, and two high school); and eight teachers selected from among four of the six campuses whose principal participated in a semi-structured interview. Additionally, responses from a principal survey were examined. Findings were organized around three themes that surfaced from the deductive and inductive analysis of data collected in response to the three research questions. The themes were: instructional leadership and other principal responsibilities, principal professional development and components of professional learning, and measuring the effectiveness of principal professional learning. Findings revealed that there are many offerings of professional development opportunities available to principals in Learning ISD. The components essential in effective principal professional learning opportunities in the studied district consisted of embedding social capital, professional capital, and decisional capital to develop contingency leadership skills. Measuring the effectiveness of principal professional learning remains an area of growth for the district studied as well as the adherence to a meaningful principal evaluation system that can properly quantify and qualify a campus administrator's effect on school improvement and student learning.
Examining Usability, Navigation, and Multimedia Learning Principles in an Intentionally Designed Asynchronous Online College Course: A Usability Study
Authors:   , Surrency Monica J
Published: January 2025

This qualitative study examines an asynchronous online course from a private university utilizing a template model for all online courses to provide students with consistent navigation and course structure throughout their degree program. The asynchronous online courses are purposely created using three criteria of quality course design: navigation is intuitive, information is chunked, and instructions are written clearly. A two-part usability test was conducted with three internal and three external participants. The two-part usability test focused on course navigation and examined the signaling, segmenting, and coherence principles applied to course content page layouts. Transcripts from the usability tests and observational field notes were coded through an iterative process in Nvivo. Through emic and etic coding, seven main categories were identified: user experience, cognitive load, multimedia learning principles, page design and layout attributes, course navigational attributes, course attributes and information, and participant navigational behavior. The findings for first-day navigation, general navigational behaviors, and perceptions of design elements used to implement the signaling, segmenting, and coherence principle are discussed. Course design recommendations for creating a positive usability experience and suggestions for future research are provided.
Post-Intentional Phenomenological Approaches to Understand the Lived Experiences of Students Learning with a Game in Higher Education Art Appreciation
Authors:   , Valdez Marie-Claire
Published: January 2025

This study encompasses my attempt to understand the lived experience of students in a higher education art appreciation course when a traditional textbook was replaced by a computer game. The methodology uses a mixture of phenomenological interviews and games as well as game machines to interpret these lived experiences. The process of allowing the research to dictate the direction I would take in my research is central to my research process. The initial research idea evolved into three research games and three versions of those games by using the data from student interviews as a generative data. The implications from this study focus upon creating new pedagogical interventions in the form of a studious labyrinthian pedagogy rather than a finite maze-like approach to art education. This dissertation examines how art education can benefit from more freedom and exploration for students to navigate their own learning.
Navigating Musical Tensions: African American Themes against Western Structure in Florence B. Price's (1887-1953) Piano Sonata in E minor
Authors:   , Chun Yeo Hun
Published: January 2025

Florence Price (1887–1953) was one of the most important African American woman composers of the early twentieth century. Price's music is known for combining techniques of Western art music with elements of the African American musical heritage. Although Price composed many works for piano, from large virtuoso pieces to characteristic miniatures, this study will address only her Piano Sonata in E minor. The purpose of this study is to analyze this sonata and discuss her compositional techniques and musical style as a combination of African American elements and Classical European procedures, combined and coordinated yet remaining in tension. Traditional European harmony, tonality, and form are successfully combined with African American characteristics: pentatonic scale, spirituals, syncopations, repetition, and dance rhythms. Indeed, Price's work is a considerable achievement, and she is one of the important African American women composers who should be better recognized today.
"I disappear in this whole big world": Re-storying the Bearers of Music Culture in the U.S. Academy
Authors:   , Crawford Michael O.
Published: January 2025

Current practices in music education parallel the expansion of globalization and cross-cultural contact. However, the multicultural music education movement—referred to by some as "world music education"—has been primarily about the diversity of musical experiences and less about the circumstances and processes of the music itself. As a result, Western music educators often neglect inseparable learning pathways and unintentionally distort the meaning and value of diverse musics from around the world. While there is considerable research examining the teaching and learning of diverse music cultures, significant portions of that literature only represent the observed accounts of cultural outsiders. In this study, I examined the lived experiences of world music culture bearers who teach in Western university institutions in the Southwest region of the United States. I used narrative inquiry to learn more about their pedagogical experiences and documented their storied accounts of interactions with university students. I based the theoretical framework in this study on Clandinin and Connelly's narrative inquiry three-dimensional space model and Schippers' twelve continuum transmission framework. My primary findings revealed that teaching in a cross-cultural setting involves several musical and contextual choices. Moreover, the perceived authenticity of the research participants' transmission processes was often a byproduct of their teaching realities—the intersection of their music culture and Western institutional structures—and included numerous adaptations. As was the case with all three participants, their past experiences constituted their present teacher knowledge and became a significant part of how they perceived their futures.

Take the Trouble to Compile a Whole New World: The Role of Event-Based Participatory Projects in Institutional Archives
Authors:   , Roeschley Ana Knezevic
Published: January 2025

Event-based mediated participatory archives, in which communities of ordinary people contribute their records to archives during collection day events represent a paradigm shift within the archival field. Applying a qualitative approach, this study investigates event-based mediated participatory archives using Bastian's communities of records and memory as a guiding framework. Using the Mass. Memories Road Show as a case study, data collection and analysis took place over three phases. In Phase I, archive supporting documents were collected and analyzed using "against the grain" historical analysis methods. In Phase II, data from the Mass. Memories Road Show digital collections were collected and analyzed using grounded theory analysis methods. In Phase III, ethnographic research data, including a direct observation and semi-structured interviews, was collected and analyzed using ethnographic analysis methods. The results of this study suggest that community participants' motivations to contribute to participatory archives are rooted in self-fulfillment while institutional archives personnel members' intentions are based in inclusive community-building. Furthermore, the contribution of records to the archives allows community participants to share personal stories that serve as evidence of their historical legacies and as affirmation of their roles in their communities. Throughout the findings, moments of connection which enable the sharing of stories are highlighted—speaking to the importance of the collection day event.
Pressure Controlled Topochemical Polymerization in Two-Dimensional Hybrid Perovskite
Authors:   , Abu-Amara Lama Marwan
Published: January 2025

Mechanical pressure offers unique control over the energy landscape of chemical reactions, opening up pathways that are inaccessible through conventional thermochemistry. We hypothesize that the reduced dimensionality defines the conformational space of the high-pressure reaction, giving rise to new selectivity that is unavailable in 3D systems. Here, we demonstrate this concept through the pressure-controlled topochemical polymerization of the diacetylene molecule deca‐3,5‐diyn‐1‐amine (DDA) incorporated in the two-dimensional (2D) perovskite [DDA]2PbBr4. Compression at 3 GPa drives the first topochemical polymerization through 1,2 addition, forming a polyene product at room temperature. The reaction is initiated by the mechanical bending of the linear DDA molecule, a mechanism fundamentally different from the 1,4-addition in 3D solids. Importantly, pressure hinders the second 1,2-addition by disfavoring the gauche conformation between the remaining acetylene groups, allowing for the selective formation of polyene versus polyacene products. We characterize the reaction mechanisms and products using spectroscopies (Raman, X-ray photoelectron, ultraviolet-visible), X-ray diffraction and density-functional theory simulations. These results highlight the important role of dimensionality in high-pressure chemistry, and offers a new paradigm for creating low-dimensional functional materials.
The Role of Maternal Health Literacy within Mother-Preterm Infant Attachment: A Meta-Analysis of Maternal Sensitivity Interventions
Authors:   , Lopez Mark A.
Published: January 2025

The present study systematically reviewed and statistically summarized the current body of literature on the relationship between maternal health literacy and maternal sensitivity, and the effect of these two variables on mothers' care and decision making on distal attachment outcomes. In so doing, a systematic review of the extant peer-reviewed, published literature examining the effectiveness of interventions in effort to improve health literacy and maternal sensitivity, with a focus on increasing the quality of mother-preterm infant attachment outcomes, was undergone. This was followed by four multilevel random effects meta-analyses. Results indicated that mothers who participated in health literacy (maternal sensitivity) interventions had, on average, higher attachment quality, in comparison to those who did not participate. Additionally, maternal age was found to be a statistically significant predictor of the overall average effect size. This suggests that maternal health literacy may be a yet unexplored correlate of mother-preterm infant attachment outcomes.
Experiences of Parents of Preadolescents with Child–Parent Relationship Therapy

Published: January 2025

Preadolescence is a time of emotional, physical, social, and relational changes, which can lead to mental health concerns. Parents of preadolescents also experience changes within their roles as parents, and both parents and preadolescents experienced a wide range of changes and challenges during the COVID-19 pandemic. A mental health intervention focused on enhancing the parent-child relationship among parents of preadolescents is important for overall family functioning. This phenomenological study explored the experiences of parents of preadolescents after participating in a virtual child-parent relationship therapy (CPRT) intervention. Participants were seven parents ages 35 to 56 years-old with preadolescent children between the ages of 9 to 12 years-old. Semi-structured interviews were conducted following the CPRT intervention and analyzed. Six themes were found, including impact of group on learning, child's engagement with parent, child qualities, parent's understanding of self, importance of parent-child relationship, and integration of CPRT skills. The emerging themes indicated that the seven participants experienced changes in themselves, in their child, and in their parent-child relationships. Participants discussed their experiences with the virtual format and their integration of CPRT skills. The participants also reported feeling closeness and support from other group members, even with the virtual format. Findings from this study highlight several clinical implications for working with parents of preadolescents virtually using CPRT. Recommendations for future research are discussed.
Algebraic Trait for Structurally Balanced Property of Node and Its Applications in System Behaviors
Authors:   , Du Wen
Published: January 2025

This thesis targets at providing an algebraic method to indicate network behaviors. Furthermore, for a signed-average consensus problem of the system behaviors, event-triggering signed-average algorithms are designed to reduce the communication overheads. In Chapter 1, the background is introduced, and the problem is formulated. In Chapter 2, notations and basics of graph theory are presented. It is known that the terminal value of the system state is determined by the initial state, left eigenvector and right eigenvector associated with zero eigenvalue of the Laplacian matrix. Since there is no mathematical expression of right eigenvector, in Chapter 3, mathematical expression of right eigenvector is given. In Chapter 4, algebraic trait for structurally balanced property of a node is proposed. In Chapter 5, a method for characterization of collective behaviors under directed signed networks is developed. In Chapter 6, dynamic event-triggering signed-average algorithms are proposed and proved for the purpose of relieving the communication burden between agents. Chapter 7 summarizes the thesis and gives future directions.
