State Capacity, Security Forces and Terrorist Group Termination
Authors:   , Kirisci Mustafa
Published: February 2025

This dissertation examines how different forms of state capacity affect the decision of terror groups to end their campaign. Building a theoretical framework about the relationship between state capacity and terrorist group termination, I address the following research questions: How do terror groups respond to the changes in non-repressive forms of state's capacity, such as bureaucratic capacity, extractive capacity, and how do those responses of terror groups affect the chance of their demise? How do the changes in non-repressive forms of state capacity affect the likelihood of termination of particular types of terror groups, specifically ethnic terror groups? And finally, how do security forces representing repressive capacity of states affect the probability of a terrorist group end? I argue that as the state fighting the terror group increases its capacity, that will generate an incentive for the terror group to respond to increasing state capacity to secure its survival and maintain its existence. As the terror group produces responses to increasing state capacity in terms of rebuilding its capacity to operate and keeping its popular support base intact, it will be less likely to end its terror campaign. This argument is particularly relevant for terror groups operating on behalf of a certain ethnic or religious group. I test this theory by doing a cross-national quantitative analysis as well as doing a qualitative analysis on the PKK's terror campaign in Turkey in the period of 1984-2013. I find that increasing extractive capacity and bureaucratic capacity of states encourages terror groups to engage in coercive and non-coercive actions to survive increasing state capacity, thereby reducing the chances of ending its terror campaign. I also argue that security forces, who represent repressive capacity of states, also play a role on the decision of terror groups to end their campaigns. By focusing exclusively on militarized law enforcement forces, I contend that the presence of these forces might either enhance the chances of survival of terror groups or increases the risk of the demise of these groups. Whether having these forces increases or decreases the likelihood of terror group end is a function of the capacity of the state to control the actions and behaviors of security forces. By constructing a time series cross-sectional data set on militarized law enforcement forces, I test these arguments and find that having militarized law enforcement forces decreases the risk of terror group end, but as the state's bureaucratic capacity increases, having these forces increases the likelihood that the terror group will decide to end its campaign. These empirical findings have several theoretical implications for the extant literature on state capacity and terrorism, and they also have implications for policymakers in terms of designing an effective counter-terrorism policy to deal with the threats from terrorist groups.
The Influence of Emergency Department Wait Times on Inpatient Satisfaction
Authors:   , Wood John
Published: February 2025

Patient satisfaction dimensions have a wide ranging and significant impact on organizational performance in the healthcare industry. In addition, the Centers for Medicare and Medicaid Services Hospital Value Based Purchasing (HVBP) Program links patient satisfaction to Medicare reimbursement, putting millions of dollars at risk for health systems. A gap in the literature exists in the exploration of how a patient's experience in the emergency department affects their satisfaction with inpatient services. In a multiple regression analysis, the relationship between HVBP Patient Experience of Care and hospital level factors including emergency department wait times are explored. Results indicate a statistically significant relationship between hospital level factors and standardized measure of patient satisfaction with a moderate adjusted effect size (p= <.0001, R2 adjusted= 0.184). Emergency department wait times post physician admit orders were most salient in predicting patient satisfaction scores (rs2= 0.434, β= -0.334, p= <.001). Recommendations to improve emergency department wait times include focusing on key decision points and implementation of electronic systems to support the movement of admitted patients out of the emergency department as quickly as possible.
Teaching Children How to Stay Still Using Movies to Provide Continuous Feedback
Authors:   , Otero Maria Jose
Published: February 2025

External beam radiation therapy is often used as a form of treatment for individuals diagnosed with cancer. However, because staying completely still can often be difficult for children, sedation is often used daily to remedy the need for stillness. In this document, we introduce the development, implementation, and testing of a technology designed to teach healthy children to self-monitor and control their movements. This technology monitored a child's body movement and created a continuous feedback loop, playing a preferred movie based on the amount of body movement observed. Study 1 compares the amount of body movement observed when children were instructed to remain still (instructions alone) to access to a movie contingent on maintained low rates of movement (contingent movie). Study 2 compares the amount of body movement observed in the instructions alone condition with two other conditions: non-contingent access to a movie (non-contingent movie) and contingent movie. Study 3 compares the amount of body movement observed in the instructions alone condition to the contingent movie condition over an extended period of time. Lastly, Study 4 compares the amount of body movement observed when children have previously been taught to stay still using the technology described above across various days throughout various conditions. Generally, we found three things: a) instructions alone were insufficient to produce the level of control over motion required; b) some control over motion was established in the non-contingent movie condition relative to the instructions alone condition; and c) the combination of movies and feedback contingent on movement was necessary to gain the level of control over body motion necessary to adhere to the medical protocol.
Optical Brain Imaging of Motor Cortex to Decode Movement Direction using Cross-Correlation Analysis
Authors:   , Lebel Cynthia
Published: February 2025

The goal of this study is to determine the intentional movement direction based on the neural signals recorded from the motor cortex using optical brain imaging techniques. Towards this goal, we developed a cross-correlation analysis technique to determine the movement direction from the hemodynamic signals recorded from the motor cortex. Healthy human subjects were asked to perform a two-dimensional hand movement in two orthogonal directions while the hemodynamic signals were recorded from the motor cortex simultaneously with the movements. The movement directions were correlated with the hemodynamic signals to establish the cross-correlation patterns of firings among these neurons. Based on the specific cross-correlation patterns with respect to the different movement directions, we can distinguish the different intentional movement directions between front-back and right-left movements. This is based on the hypothesis that different movement directions can be determined by different cooperative firings among various groups of neurons. By identifying the different correlation patterns of brain activities with each group of neurons for each movement, we can decode the specific movement direction based on the hemodynamic signals. By developing such a computational method to decode movement direction, it can be used to control the direction of a wheelchair for paralyzed patients based on the changes in hemodynamic signals recorded using non-invasive optical imaging techniques.
Finding a Data-Driven Definition of Binge-Watching
Authors:   , Kelly Megan Erin
Published: February 2025

Binge-watching, the act of watching large amounts of television at a time, has become a popular phenomenon internationally; however, it has yet to be sufficiently defined. In order to define binge-watching, data was collected on specific watching instances from 216 undergraduate students at a large research university. Hierarchical and k-means cluster analyses were conducted in Phase I to empirically determine how binge-watching should be defined. In Phase II, that definition was tested by correlating the number of instances of binge-watching in a one-week period, collected by seven days of daily diary logs, with several theoretically related measures including body mass index, dissociative tendencies, psychological distress, compulsion to watch, boredom proneness, and escapism through watching. The data-driven definition was found to be that eight hours or more of continuous watching was binge-watching, while anything less than that was not. In Phase II, the frequency of binge-watching through the seven-day period was calculated based on that new definition. The frequency of binge-watching was positively correlated with body mass index and dissociative tendencies with statistical significance at the alpha = .05 level. Compulsion to watch was not statistically significant; however, there was a positive correlation. These findings indicate that the proposed data-driven definition has concurrent validity. Psychological distress, boredom proneness, and escapism through watching were not statistically significantly related to binge-watching frequency, nor did the effect sizes indicate a correlation may exist. Potential reasons for these results are discussed. The definition found in this study will be helpful to other researchers as research into binge-watching continues to grow.
Child-Centered Canine-Assisted Therapy: An Investigative Look at Integrating Therapy Dogs into Child-Centered Play Therapy
Authors:   , Talley Lindsay P
Published: February 2025

Play therapy and animal-assisted therapy are two specialized modalities within the field of counseling. Child-centered play therapy (CCPT) is a specific theoretical approach to play therapy that regards the therapeutic relationship as the primary healing factor. With much empirical support, CCPT is considered an effective mental health treatment option for working with children. Animal-assisted therapy in counseling (AAT-C) is acknowledged in the literature as a supplemental treatment modality to an existing counseling practice. Although past researchers have shown support for AAT-C as well as CCPT, there is a current dearth of literature examining the integration of these approaches. The present study sought to understand the approach of incorporating a therapy dog into child-centered play therapy while maintaining theoretical consistency. Using a constructivist grounded theory approach, I facilitated child-centered canine-assisted play therapy (C3APT) services for four children and reviewed the sessions with expert supervisors in AAT-C and CCPT. Three major themes emerged from the data: (a) principles of C3APT, (b) procedures of C3APT, and (c) relational dynamics. Implications for clinical practice and training of both therapy dogs and C3APT practitioners are also discussed.
High School Teachers and Support Staff's Attitudes toward Students with Disabilities in the Inclusive General Education Classroom
Authors:   , Yoakum Carrie Mae
Published: February 2025

Research has shown teachers' attitudes toward students with disabilities directly affect the students' performance in the general education classroom; however, more research is needed to determine what variables influence high school teacher and support staff attitudes. The purpose of this study was to determine the attitudes of high school general education teachers, special education teachers, and support staff toward students with disabilities in the general education classroom. The study examined multiple variables such as gender, race/ethnicity, teaching experience, educators' role, and school size; and the impact of professional development on their attitudes toward inclusion. This study used an explanatory sequential mixed-methods design. Data collection included the Inclusion Attitude Scale for High School Teachers (IASHST), developed by Ernst and Roger, and then focus groups for general education teachers, special education teachers, and support staff in order to triangulate the findings. The results of this study found that general education teachers may have a more negative attitude than special education teachers and support staff. However, it is important to note that members of each focus group described what they considered to be appropriate exceptions to including students with disabilities in the general education classroom.
District Systematic Supports of an Instructional Coaching Program
Authors:   , Webb Mary Katherine
Published: February 2025

The purpose of this qualitative study was to identify the systems, structures, and behaviors district leaders employ and enact to assist elementary school principals' relationship with their school instructional coach. Through the synthesis of current research, the conceptual framework was developed with a focus on district leadership behaviors and instructional coaching programs. The conceptual framework consisted of professional capital theory, instructional coaching model, and principal leadership skills. This study assessed the perceptions of six instructional coaches, six elementary principals, and three district leaders from Comet ISD regarding the specific behaviors district leaders use to support the relationship between the school principal and instructional coach. The three-part data collection process included document analysis, face-to-face interviews, and focus group interviews to support the triangulation of data. Through the a priori coding process, four themes emerged that identified key district structures and leadership behaviors needed to support the relationship between the school principal and instructional coach: program clarity, principal leadership skills, professional learning opportunities, and culture of continuous learning. This study revealed a specific need to understand program implementation, accountability, and evaluation of the effectiveness of the instructional coaching program in a fast-growth district.
La vía del abandono en los cuentos de Amparo Dávila
Authors:   , Lopez Rodrigo
Published: February 2025

Amparo Davila's writing style is characterized by circumventing the boundaries between the real and the fantastic and between the known and the unknown. The author creates a narrative that evokes horror in the reader by mixing the uncanny of the unknown with the reality of the world. This study proposes that the sinister in Davila's stories are created by abandonment. This abandonment is the peremptory element of Davilian narrative and can be seen and examined throughout the author's literary work. The abandonment wields a mechanism of loneliness, madness, hopelessness and chaos that eventually provokes the sinister. The element of abandonment disturbs the main character of the story and makes him fall into an abyss from which he or she cannot escape. This abandonment is not always obvious, since most of the time the abandonment is veil by a halo of gothic and fantastic elements. The present thesis has the task of breaking down the different types of abandonment that are presented throughout this narrative, its sinister function and the theoretical and historical interpretation of the various abandonments both personal and collective that Amparo Davila presents. The route of abandonment proposed in this thesis is explained in the following three stories: "El desayuno" (1961), "La quinta de las celosías" (1959) and "La señorita Julia" (1959).
As the Need Presents Itself: Social Identity Theory and Signaling in Online Crowdfunding Campaigns
Authors:   , Hamilton Scott J
Published: February 2025

As social interactions increasingly become exclusively online, there is a need for research on the role of identity and social identity in online platforms. Drawing on Symbolic Interactionist approaches to identity, namely Social Identity Theory and Identity Theory, as well as Signaling Theory, this study argues that actors will selectively use religious language to signal their credentials to an audience for the purpose of garnering prosocial behavior in the form of donations to their fundraising campaign. Using latent semantic analysis topic models to analyze the self-presentations of crowdsourcing campaigners on GoFundMe.com, this study found evidence for the presence of signaling to a religious identity online as well as a significant difference in the presentation of need for campaigns originating in areas with high reported religiosity compared to campaigns from areas of low religiosity. In comparison to other campaigns, campaigners engaging in religious signaling were significantly increasing their donations. I suggest that strategically chosen religious topics in online crowdfunding is an example of low-cost identity signaling and provides insight into how signaling happens online and the potential outcomes resulting from this cultural work.
Computational Development of Trimetallic Cyclotrimers for Gas-Filtration Applications through Non-Covalent Interactions
Authors:   , Williams Christopher M.
Published: February 2025

Photophysical properties of an array of various polyaromatic hydrocarbons were benchmarked with B3LYP, M06 and B97D methods coupled with Pople and CEP-31G(d) basis sets. Results from the benchmark show the importance of diffuse basis sets when modeling the electronic properties of highly conjugated systems and provide qualitative reliable accuracy with certain levels of theory. B97D and M06 are applied to modeling pyrene adducts governed by non-covalent interactions in both gaseous and condensed states to reproduce experimental spectra. DFT calculations with both B97D and M06 functionals show qualitatively and quantitatively that pyrene dimer is a stronger π–base as compared to its monomer. Binding energies coupled with MEP, PCA and Qzz results show that the difference in π-basicity of the monomer and dimer impacts the supramolecular chemistry involved in adducts formed with super π-acidic silver cyclometallic trimer (CTC). Non-covalent interactions between coinage metal CTCs and ammonia/phosphine substrates is reported. Interactions between these substrates and the facial plane of the π-rich gold CTC reveal a novel interaction, where the typical Lewis acid/base roles are reversed for the substrates. Adducts formed through this type of interaction define typical Lewis bases like ammonia and phosphine as Lewis acids, wherein the partially positive hydrogens coordinate to the metallo-aromatic center through dipole-quadrupole interactions. Interactions of ammonia at the side positions is shown to heavily impact the Lewis basicity of the CTC facial plane leading to similar interactions exhibited by the ammonia-gold CTC adducts. Structural and electronic properties of the adducts modeled are examined.
The Teaching of 21st Century Skills through Project-Based Learning and Professional Development for Career and Technical Education
Authors:   , Petrunin Kristin Firmery
Published: February 2025

The purpose of this non-experimental, quantitative study is to investigate the relationship between the use of project-based learning (PBL) by secondary business teachers and time spent in professional development of secondary business teachers for the teaching of 21st century skills. The four identified 21st century skills that will be researched include: (1) critical thinking, (2) collaboration, (3) communication, (4) creativity and innovation. A sample of 316 secondary business teachers were surveyed about their classroom practice and reflection of teaching 21st century skills. This study used a modified version of the 21st Century Teaching and Learning Survey. Survey results were analyzed for relationships using correlational and regression analysis. Business teachers reported a statistically strong relationship between the use of PBL and the teaching of 21st century skills. A statistically significant relationship between time spent in professional development and the teaching of 21st century skills was not found. Regression results indicated that the use of PBL had an impact on the teaching of 21st century skills. This research guides teachers, school administrators, and CTE directors at the state and district level towards the creation of professional development and implementation strategies when applying PBL methods in career and technical education settings.
Analyzing Learning Acquisition and Retention in a WebVR Environment
Authors:   , Lepcha Samson Den
Published: February 2025

The primary purpose of this study was to determine if WebVR enhances the knowledge retention regarding mechanical components of high-risk moving machinery, specifically elevators. There were 23 participants divided into a treatment group and comparison group. The treatment group used WebVR to take a virtual elevator machine room tour while the comparison group studied printed images of the same elevator machine room. These alternative activities were conducted prior to a field trip to a real elevator machine room. Gains in knowledge pre to post were measured and compared between the treatment and comparison groups. The research findings showed an overall gain in knowledge for the participants in the elevator bootcamp. More in depth analysis showed the treatment group exhibited significant gains for six of the ten knowledge areas while the comparison group exhibited significant gains in three of the ten targeted knowledge areas. The treatment group gained more knowledge on components higher than eye-level while the comparison group scored better on components that were below eye-level or on the floor. Both groups were seen actively engaged in the field trips. The treatment group members exposed to the virtual reality elevator machine room frequently referred to what they saw in the WebVR while the comparison group did not refer to their printed images while on an actual tour of the elevator machine room. Virtual reality training of this type has the potential to improve basic knowledge and safety trainings. Added, it provides trainings to large numbers of people across the globe who would otherwise not receive such training. This type of training has the potential to save the lives of workers in high risk electro-mechanical spaces and similar settings in different industries.
A Performance Guide to David Kechley's "In the Dragon's Garden" with an Investigation of the Saxophone-Guitar Duo Genre
Authors:   , Pierce Justin
Published: February 2025

American composer David Kechley was profoundly impacted by a 1990 trip to the Ryoan-ji Temple in Kyoto, Japan. The composer describes the finely raked, small white stones in the midst of fifteen large rocks in the Japanese Zen garden as "planned randomness." Kechley's inaugural composition for saxophone-guitar duo, In the Dragon's Garden, reflects his experience at the Ryoan-ji Temple. The use of minimalistic compositional techniques without literal repetition in the work represents a departure from the first generation of Minimalist composers, such as LaMonte Young, Steve Reich, Phillip Glass, and John Adams. An analysis of minimalistic compositional elements, combined with an interview with the commissioning ensemble, the Ryoanji Duo, provides insights into the interpretation and preparation of this complex work. Furthermore, this document contains helpful information pertinent to the saxophone-guitar duo. Details on balance and amplification, orchestration, and collaboration with the composer will supply performers and composers with essential knowledge needed to participate in this growing musical medium.
Biopedagogy of Rumination and Regurgitation
Authors:   , McIntosh Shoshana
Published: February 2025

Regurgitating test answers, needing more time to digest a reading, or being spoon fed information are just a few of many digestive metaphors currently used in education. In taking seriously the use of these metaphors, I suggest that humans recognize a connection, on some level, between the mental act of taking in and processing knowledge and the physical act of digestion, yet in educational discourse, these processes are more often than not cast in a negative light. The following philosophical exploration begins with a close look at two digestive practices, rumination and regurgitation, in non-human animals such as ruminants, seed-eating birds, and honey bees. By looking to these animals, it becomes possible to rehabilitate an affirmative human version of rumination and regurgitation in which our physical and mental selves are intrinsically intertwined in and through bodily education. The works of Giorgio Agamben, Tyson E. Lewis, Nathan Snaza, and Vinciane Despret support a theoretical framework which moves beyond human-centered education towards the development of an inhuman biopedagogy that embraces digestion rather than discriminates against it. I offer practical applications of rumination and regurgitation, shedding light on moments when rumination and regurgitation are already present in education, and introduces slight adjustments to these practices to enhance their positive digestive dimensions. The multi-species practices of rumination and regurgitation invite students and educators alike to slow down, return to material that needs to be rechewed, and ultimately to embrace an embodied experience of education.
"The Last Leaf" for Sopranino Saxophone: A Performance Guide and Interview with Chaya Czernowin
Authors:   , Richards Alexander
Published: February 2025

Despite being one of the instruments outlined in Aldophe Sax's original patent for the saxophone, and commercially available since 1849, the sopranino saxophone was generally unaccepted as a fully-fledged instrument until the late 20th century, existing solely as a novelty or a rare member of the saxophone ensemble. As such, there are few saxophonist who utilize the instrument, and the literature for the sopranino saxophone exists primarily in the contemporary idiom. Of the contemporary works for sopranino saxophone, one of the most well-known pieces is Chaya Czernowin's The Last Leaf (2011/12). While Czernowin initially conceived this work for solo oboe, she subsequently arranged a version for sopranino saxophone. Since then, it has been performed many times and recorded by several saxophonists including Ryan Muncy and Patrick Stadler. Through an examination of the score utilizing a variety of sopranino saxophone-centric contemporary resources alongside an interview with Czernowin herself, this dissertation provides the first extant performance guide to the sopranino saxophone edition of The Last Leaf, with the purpose of providing any saxophonists wishing to attempt this work with the information of Czernowin's intention for the piece and how to implement the techniques necessary for a performance.
Optimization of RSA Cryptography for FPGA and ASIC Applications
Authors:   , Simpson Zachary P
Published: February 2025

RSA cryptography is one of the most widely used cryptosystems in the world. FPGA/ASIC implementations for the classic RSA cryptosystem have high resource utilization due to the use of the Extended Euclid's algorithm for MOD inverse generation, the MOD exponent operation for encryption and decryption, and through non finite-field arithmetic. This thesis translates the RSA cryptosystem into the finite-field domain of arithmetic which greatly increases the range of encryption and decryption keys and replaces the MOD exponent with a multiplication. A new algorithm, the SPX algorithm, is presented and shown to outperform Euclid's algorithm, which is the most widely used mechanism to compute the GCD in FPGA implementations of RSA. The SPX algorithm is then extended to support the computation of the MOD inverse and supply decryption keys. Lastly, a finite-field RSA system is created and shown to support character encryption and decryption while being designed to be integrated into any larger system.
Our Own and the Others: What Happens to Perceptions of Immigrant Threat when Value Priorities Collide?
Authors:   , Grigoropoulou Nikolitsa
Published: February 2025

With immigration controversies increasingly found at the forefront of the European public arena, understanding the social and cultural forces driving negative perceptions of immigrants becomes a pressing task of academic scholarship. Situated within the broader theoretical framework of group-conflict theories, human values theory and social identity theory encourage different interpretations of how our interest to the welfare of the people closest to us (benevolence) and the broader human community (universalism) can inform attitudes towards immigrants. Human values theory argues for a unidirectional, negative effect of benevolence and universalism on negative perceptions of immigrants, while social identity theory suggests that, unlike universalism, benevolence would increase such perceptions. The present study seeks to examine how self-transcending human values (a.k.a. benevolence and universalism) affect perceptions of immigrant threat and whether the locus of our value priority matters. Using nationally pooled data from the European Social Survey (ESS) for 15 European countries, the results provide robust evidence that benevolence and universalism affect perceived immigrant threat in opposite directions, generally aligning with the propositions of the social identity theory. The group we place our loyalty matters. At the same time, national context matters too suggesting that grand scheme interpretations of this phenomenon fall short. Theoretical implications and future directions are further discussed.
The Rise and Fall of the Greenback Party in Texas: Economic Change and Political Dissent in the Post-Civil War Era
Authors:   , Sinclair Cameron L.
Published: February 2025

In 1873, a financial crisis plunged the United States into a deep economic depression that exacerbated a number of post-war economic issues. By the late 1870s, political dissent centered primarily on financial issues merged into the Greenback movement, which represented a loose coalition of reformers calling for economic relief based on the expanded use of greenbacks (paper currency issued by the United States Treasury during the Civil War). The Greenback Party emerged as a direct response to federal financial policies, but in Texas, it also provided a broad political platform for those opposed to the policies of "Redeemer/Bourbon" Democrats. The Greenback Party of Texas brought together a wide range of dissenters, including disgruntled Democrats, ousted Republicans, and many different economic and social reformers. From 1876, when the first Greenback clubs appeared in Texas, to the Greenback Party's virtual disappearance after the election of 1884, the Texas Greenbackers reached across boundaries of section, race, class, and sometimes gender; brought together farmers, workers, and professionals; Southerners and Northerners, white and black; former Confederates and former Unionists; native-born Americans and immigrants; and received sizable support from multiple counties in the northern, eastern, and central part of the state. In spite of its short run in Texas, the Greenback movement demonstrates both the complexity of Texas politics after Reconstruction and the failure of Democratic leaders to adequately address economic issues resulting from post-bellum economic changes. The movement also laid the foundation for many future reform movements with the articulation of an antimonopoly political tradition.
Evaluating the Effects of the D.A.N.C.E Training System on Staff and Child Responding
Authors:   , Morales Erendira
Published: February 2025

The purpose of this study was to evaluate and systematically replicate the effectiveness of the DANCE training for a staff member to be an effective change agent for the children in her care, while maintaining the organization's and family's values. The study was conducted in an organization that values and focuses on building rapport, avoids the use of coercive procedures, and teaches children in a caring and meaningful way. A multiple baseline across indoor and outdoor settings was used to evaluate the effects of the package. Results demonstrated that DANCE training was an effective procedure to teach a staff member how to increase teaching interactions. Harmonious engagement, instructional engagement and vocal approximations also increased while challenging behavior maintained at zero levels.
A Holy Night: 10 Arrangements of Timeless Carols: Preparing Early Advanced Piano Students for Standard Repertoire
Authors:   , Nahkur Hando
Published: February 2025

It is often challenging for early advanced piano students to move from intermediate level repertoire to standard repertoire because the techniques and difficulties present in the new repertoire are simply too overwhelming for them. "A Holy Night: 10 Arrangements of Timeless Carols" can help bridge the gap between the two repertoire categories by introducing several advanced techniques and combinations of techniques to early advanced students in a non-overwhelming way. Several standard techniques that were widely used by composers of different styles are addressed in the arrangements: legato and chord playing, orientation in different keys, pedaling, dynamics and octave playing. The topic of fingerings is also covered since using correct fingerings is a key for any technique to work. The arrangements help to prepare early advanced students for standard repertoire by allowing them to learn, practice, and perform a variety of standard repertoire techniques in short and engaging pieces. This dissertation is intended to demonstrate to private piano teachers ways in which this arrangement of mostly well-known seasonal tunes can be used to assist in the transition to more advanced repertoire.
The Impact of an Inquiry-Based Learning Curriculum upon Digital Awareness and Well-Being among Adolescents with Learning and Attentional Disabilities
Authors:   , Cockerham Deborah Pyle
Published: February 2025

This study investigates the effectiveness of an inquiry-based learning curriculum for middle school students with learning and/or attentional disabilities (LD and/or ADHD). The main questions asked were: To what extent can an inquiry-based learning curriculum focused on digital responsibility impact: (1) well-being; (2) smartphone usage; and (3) smartphone awareness among adolescents with LD and/or ADHD? Fifty middle school participants with LD and/or ADHD were divided into two groups, an experimental group and a control group. Findings showed a significant increase both in positive affect and in awareness of personal smartphone usage for experimental, but not control, participants, suggesting that inquiry-based learning may be an effective approach for teaching digital responsibility to students with LD and/or ADHD. Other findings indicated that social connectivity is a high priority for today's adolescents. Additional insights and implications are discussed.
Women's Access to School Superintendency Roles
Authors:   , Solomon Dana
Published: February 2025

Men continue to outnumber women in public school superintendent roles by a 4:1 ratio. However, women outnumber men by a 4:1 ratio in teaching roles in public school districts. In addition, more women than men hold superintendent certificates and educational doctorates. Due to this puzzling discrepancy, it is important to understand possible factors in the form of gendered barriers to access that could lead to the unequal representation of women in superintendent positions. In this study, I examined how these barriers manifested in the experiences of female superintendents participating in the study, how they influenced the hiring experiences of these participants, and how they impacted these female leaders throughout their careers. With this study, I investigated barriers associated with holding mechanisms, gendered norms, and gendered filters that may limit women's access to superintendent roles. Women's experiences of the origins and effects of gender normative perceptions and hiring practices have potential for contributing to the study of gender equity in the field of education and beyond. Findings could provide implications for increasing women's opportunities to serve beyond central office positions in public school districts. Possibilities exist for identifying practices in organizations that have hired women to serve at the highest level of school district leadership; that of the superintendent of schools.
Phenotype Analysis of the CISD Gene Family Relative to Mitochondrial Function in Caenorhabditis elegans
Authors:   , Mungwira Chipo F
Published: February 2025

NEET proteins belong to a unique class of [2Fe-2S] cluster proteins that have been shown to participate in various biological processes such as regulating iron, reactive oxygen species and apoptosis within the cell and are localized to the mitochondria. Disruption of the mitochondrial NEET proteins are associated with different human diseases such as obesity, neurodegeneration, cancer and diabetes. In humans, a missense mutation in the CISD2 gene results in a heritable multisystem disorder termed Wolfram syndrome 2 (WFS2), a disease which displays an early onset of juvenile diabetes and various neuropsychiatric disorders. The C. elegans genome contains three previously uncharacterized cisd genes: cisd-1, which has homology to the human CISD1 and CISD2, and cisd-3.1 and cisd-3.2, both of which have homology to the human CISD3. Disruption of the cisd-3 gene(s) function results in mis-regulation of proteostasis in the mitochondria, whereas cisd-1 and cisd-3.1 disruption impacts proteostasis in the endoplasmic reticulum. Reduction of cisd-3.2 gene function also leads to a developmental delay in C. elegans. A knockout mutation of the cisd-3.2(pn68) gene function results in various germline defects including delayed development progression and morphological defects. Furthermore, I show the cisd gene(s) and protein expression profiles is present relative to sex, tissue type and developmental stages. This work is significant because it provides further insight of the essential role of CISD-3 relative to C. elegans. Furthermore, my studies can contribute to new genetic discoveries that will widen the scientific research relative to NEET protein family studies.
Fabrication and Testing of Biomimetic Microstructures for Walkway Tribometers
Authors:   , Haney Christopher Willard
Published: February 2025

The main objective of this work is to give contribution in both additive manufacturing (AM) and tribometry derived from the application and study of materials available with the use of biomimetic designs. Additional contributions are determining what effects treatments for flooring surfaces may have on the dynamic coefficient of friction and the effects of these products on common surfaces. The validity of the proposed methodology for a proof of concept was demonstrated by comparing measured dynamic coefficient of friction for designs using standardized equipment and comparing these values to plantar skin tested using an accepted and standardized testing method that has been extensively researched and validated. Initial biomimetic designs and characteristics unique to each design were researched and compared. Eleven designs were selected to be fabricated, tested, and compared to select the most desirable applications for further investigation. Research into potential treatments commercially available for use was done to determine the efficacy of these products. Prototype sensor designs were selected and fabricated using direct light processing (DLP) technology. Examination of the measured values was done through an analysis of the variances in the response variable and comparisons using Fisher and Tukey pairwise comparison method. Future work recommendations are provided for further development and improvement of the topics presented in this thesis.

In view of the long wait times for women and the lack of accessibility for LGBTQ+ individuals when they use restrooms, this case provides a set of analytical tools to evaluate wait time disparity among users for different restroom configurations. A stadium manager who faces complaints about excessive restroom wait times aims to retrofit the restroom layout to improve both efficiency, measured in terms of wait time, and fairness, measured in terms of totalitarian and Rawlsian scores. Given that customers have diverse preferences over the use of restroom types, in three modules, students learn to (i) evaluate queuing parameters for a mix of heterogeneous populations, (ii) evaluate queuing metrics for various restroom layouts and discuss their wait time disparities, and (iii) evaluate and discuss the fairness of access to restroom facilities from a diversity, equity, and inclusion (DEI) perspective. By completing this case, students gain an understanding of service systems, learn about process flexibility concepts, and become familiar with DEI concepts and measures. The primary objectives of the case for students are to understand the trade-offs between efficiency and fairness, develop an understanding of multiobjective problems, and improve their skills in employing queuing concepts and tools.

Nanopatterned parametric oscillators for laser conversion beyond an octave

Published: February 2025

Many uses of lasers place the highest importance on access to specific wavelength bands. For example, mobilizing optical-atomic clocks for a leap in sensing requires compact lasers at frequencies spread across the visible and near-infrared. Integrated photonics enables high-performance, scalable laser platforms. However, customizing laser-gain media to support wholly new bands is challenging and often prohibitively mismatched in scalability to early quantum-based sensing and information systems. Here, we demonstrate a tantalum pentoxide microresonator optical-parametric oscillator (OPO) that converts a pump laser to an output wave within a frequency span exceeding an octave. We control phase matching for oscillation by nanopatterning the microresonator to open a photonic-crystal bandgap on the mode of the pump laser. The photonic crystal splits only the pump mode and preserves the broader mode structure of the resonator, thus affording a single parameter to control output waves across the octave span using a nearly fixed frequency pump laser. We also demonstrate tuning the oscillator in free-spectral-range steps, more finely with temperature, and minimal additive frequency noise of the laser-conversion process. Our work shows that nanophotonic structures offer control of laser conversion in microresonators, bridging phase-matching of nonlinear optics and application requirements for laser designs.
The VisionDial: Engineering, Development, and Assessment of an Affordable and Compact Phoropter
Authors: Lyakhov Michael
Published: February 2025

Abstract
Purpose: The VisionDial was developed to address the global challenge of uncorrected refractive errors, affecting over 33% of individuals due to limited access to vision care. This study aimed to create a low-cost, compact phoropter capable of precise optical and axis defect correction, focusing on affordability and accessibility for underserved populations.
Procedure: The VisionDial employs continuous lens rotation and translation adjustment mechanisms for enhanced accuracy. Constructed using 3D-printed components, the device reduces production costs to $37.16. Testing involved a simulated eye setup under controlled conditions. Modulation Transfer Function (MTF) analysis was performed on Siemens Star, Snellen Chart, and Pinhole Test images to evaluate visual clarity improvements and correction accuracy.
Results: The VisionDial demonstrated a tenfold improvement in image clarity and achieved correction errors as low as 0.1 diopters, surpassing the precision of traditional phoropters. The innovative use of 3D-printed materials ensured significant cost reductions without compromising functionality, highlighting its potential as a cost-effective alternative for vision diagnostics.
Conclusion: The VisionDial offers a transformative solution to the global burden of uncorrected refractive errors by combining precision, affordability, and accessibility. While initial testing was limited to controlled conditions, future studies will validate its performance in clinical settings and expand its diagnostic capabilities to address a broader range of visual impairments, enhancing global vision care.

Introduction

Cryptococcal meningitis remains a prominent cause of death in persons with advanced HIV disease. CSF leukocyte infiltration predicts survival at 18 weeks; however, how CSF immune response relates to CSF leukocyte infiltration is unknown.

Methods

We enrolled 401 adults with HIV-associated cryptococcal meningitis in Uganda who received amphotericin and fluconazole induction therapy. We assessed the association of CSF leukocytes, chemokine, and cytokine responses with 18-week survival.

Results

Participants with CSF leukocytes ≥50/microliter had a higher probability of 18-week survival compared with those with ≤50 cells/microliter (68% (52/77 vs. 52% (151/292); Hazard Ratio = 1.63, 95% confidence interval 1.14–2.23; p = 0.008). Survival was also associated with higher expression of T helper (Th)-1, Th17 cytokines, and immune regulatory elements. CSF levels of Programmed Death-1 Ligand, CXCL10, and Interleukin (IL)-2 independently predicted survival. In multivariate analysis, CSF leukocytes were inversely associated with CSF fungal burden and positively associated with CSF protein and immune parameters (interferon-gamma (IFN-γ), IL-17A, tumor necrosis factor alpha (TNF)-α, and circulating CD4+ and CD8+ T cells).

Conclusion

18-week survival after diagnosis of cryptococcal meningitis was associated with higher CSF leukocytes at baseline with greater T helper 1 (IFN-γ, IL-2 and TNF-α cytokines), T helper 17 (IL-17A cytokine) and CXCR3+ T cell (CXCL10 chemokine) responses. These results highlight the interdependent contribution of soluble and cellular immune responses in predicting survival and may support potential pathways for adjunctive immune therapy in HIV-associated cryptococcal meningitis.
