Novel Metal-Containing Nanoparticle Composites for Cancer Therapy and Imaging
Authors:   , Nasiri Nooshin Mirza
Published: February 2025

With all the improvements in cancer treatments, multidrug resistance is still the major challenge in treating cancer. Cells can develop multidrug resistance (MDR) during or after treatment, which will render the cancer cells resistant not only to the chemotherapy drug being used but also to many other structurally- and mechanically-different chemotherapeutics. In the first project, the main focus was on development of drug resistant cell lines by selection with taxol. Gene changes in the L1T2 cell line after treatment with Taxol was studied. Treatment of L1T2 cells with taxol leads to changes in the expression of ABC transporter proteins, whereas the combination of Taxol with protease inhibitors leads to increased efficacy via inhibition of P-glycoprotein (P-gp). In the second project, we showed that our innovatively-designed Au-loaded poly(lactide-co-glycolic acid) nanoparticles (GPLGA NPs) are able to cross biological barriers and deliver inside the cells without being recognized by the ABC protein transporter. (We focus specifically on P-gp-mediated drug efflux in a model of HEK cell lines.) The concentration of gold was measured using inductively-coupled plasma/mass spectrometry (ICP-MS) after 6- and 24-hour treatment of GPLGA NPs, which did not show significant increase of gold inside the cells in presence of the P-gp inhibitor valspodar. Cancer cells were treated with the GPLGA NPs for 24 hours and then irradiated 5 minutes at 1Wcm-2 using laser settings at 680 or 808 nm. Heat generation in cancer cells, after internalizing GPLGA NPs and laser irradiation, was significant irrespective of laser wavelength. The plasmomic heating response in this in vitro model can be a step closer to overcome MDR. Finally, for the third and last project represented in this dissertation, the focus was on the design and synthesis of innovative, biodegradable PLGA NPs, encapsulated with the platinum(II)-based non-organometallic/non-cyclometalated phosphorescent complex PTA = [Pt(ptp)2], a brightly phosphorescent complex (ptp = square-planar bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]). Size-tunable, emission-polarized phosphorescent PTA-loaded PLGA NPs were synthesized using a single-emulsion, solvent evaporation technique. Photoluminescence characterization shows that PTA-loaded PLGA NPs exhibit strong and stable orange emission with peak maximum ~ 580 nm. The photoluminescence quantum yield (QY) of the synthesized PTA-PLGA NPs was evaluated at ~55%, which allows recording of images with a much better contrast than that with PTA in organic solvents without the PLGA (QY ~0.5% and ~0 emission polarization) or even that with typical fluorescent organic dyes like rhodamines.
'The Marshall System' in World War II, Myth and Reality: Six American Commanders Who Failed
Authors:   , Carlson Cody King
Published: February 2025

This is an analysis of the U.S. Army's personnel decisions in the Second World War. Specifically, it considers the U.S. Army Chief of Staff George C. Marshall's appointment of generals to combat command, and his reasons for relieving some generals while leaving others in place after underperformance. Many historians and contemporaries of Marshall, including General Omar N. Bradley, have commented on Marshall's ability to select brilliant, capable general officers for combat command in the war. However, in addition to solid performers like J. Lawton Collins, Lucian Truscott, and George S. Patton, Marshall, together with Dwight D. Eisenhower and Lesley J. McNair, often selected sub-par commanders who significantly underperformed on the battlefield. These generals' tactical and operational decisions frequently led to unnecessary casualties, and ultimately prolonged the war. The work considers six case studies: Lloyd Fredendall at Kasserine Pass, Mark Clark during the Italian campaign, John Lucas at Anzio, Omar Bradley at the Falaise Gap, Courtney Hodges at the Hürtgen Forest, and Simon Bolivar Buckner, Jr. at Okinawa. Personal connections and patronage played strong roles in these generals' command appointments, and often trumped practical considerations like command experience. While their superiors ultimately relieved corps commanders Fredendall and Lucas, field army and army group commanders Clark, Hodges, and Bradley retained command of their units, (Buckner died from combat wounds on Okinawa). Personal connections also strongly influenced the decision to retain the field army and army group commanders in their commands.
The PICTS, Trauma, Experiential Avoidance, Criminal Thinking and Behavior in an Online Community Sample
Authors:   , Hulsey Teresa
Published: February 2025

This study sought to generalize the Psychological Inventory of Criminal Thinking Styles (PICTS) factor structure using the PICTS-Layperson (PICTS:L) in a community sample. The current study also sought to replicate previous findings that criminal thinking mediates the relationship between trauma and criminal behavior. Additionally, this study sought to explore if and/or how experiential avoidance (EA) contributes to the relationships between post-traumatic symptoms (PTS) and criminal thinking, and criminal thinking and criminal behavior. Community members recruited through Mturk, completed online measures of PTS, EA, criminal thinking, criminal behavior, and a demographics questionnaire. A confirmatory factor analysis (CFA), which was conducted to assess the PICTS:L factor structure in an online community sample, demonstrated the hierarchical second order factor structure was a good fit after problem items were removed. Mediation analyses results found that criminal thinking mediated the relationship between PTS and criminal behavior therefore replicating previous findings. Moderated mediation analyses were conducted to determine if EA moderates the relationships between PTS and criminal thinking, and criminal thinking and behavior. Findings suggest that EA plays a significant role, particularly for women who endorse relatively low EA. These and exploratory findings, limitations, implications, and future directions for work in these areas are discussed.
Anxiety Sensitivity and Nonmedical Prescription Drug Use among Adolescents
Authors:   , Carey Caitlyn
Published: February 2025

Research suggests that non-medical prescription drug (NMPD) use is becoming increasingly prevalent, particularly among adolescents. A critical step towards developing effective intervention efforts requires identifying adolescents who are at risk for NMPD use. An extensive literature suggests that both adolescents and adults with elevated anxiety sensitivity (AS) are at greater risk for problematic substance use, and a small body of work has identified similar links with NMPD use specifically among adults. However, most of this literature combines all prescription drugs into a single category, and no work has evaluated the relation between AS and NMPD use among adolescents. The current study endeavors to further this area of research by examining the relation between AS (overall and subscales) and NMPD use among adolescents. The project evaluated 276 adolescents (age 9-19 years) enrolled in a residential treatment program on level of AS, including sub-dimensions (i.e., cognitive, physical, and social), and NMPD use across three categories of drugs: analgesic (e.g., Vicodin®), anxiolytic (e.g., Xanax®), and stimulant (e.g., Adderall®). A series of logistic regression models indicated that overall AS predicted nonmedical analgesic use, but not anxiolytic/sedative or stimulant use. A closer investigation of the AS subscales demonstrated that only the AS social subscale significantly predicted nonmedical analgesic and anxiolytic/sedative use. These results suggest that AS is related to NMPD use among adolescents, highlighting the need for future work to disaggregate the assessment of NMPD use into specific drug classes and explore the subscale dimensions of AS.
Stalking Dickens: Predatory Disturbances in the Novels of Charles Dickens
Authors:   , Stuart Daniel
Published: February 2025

Stalking in the nineteenth century was a dangerous, increasingly violent behavior pattern circulating in society. It was as much a criminal act then as now, and one the Victorian novel exposes as a problematic form of unwanted intrusion. The realist novel of this period alongside its more sensational counterparts not only depicts scenes of close surveillance, obsession, and harassment as harmful. It exposes the inability of social laws to regulate such conduct. I argue Charles Dickens is the most pivotal figure in observing how stalking emerged as not only a fictional motif, but as an inescapable, criminal behavior pattern. Throughout his work and its nuanced characters, Dickens reveals underlying truths about stalking and stalkers. Early books like Barnaby Rudge and The Old Curiosity Shop feature Gothic villains and predatory motifs adapted from prior literary genres. The works of his middle period foreground stalking in the context of the modern city and institutional power. In the final decade of his life, problems associated with unrequited love examine the pathological patterns of romantic obsession in modern stalker archetypes. Such an analysis and its transformative insight perceive crucial truths about unwanted intrusion, social attachment, and problem of predatory behavior.
Early Music Audiences: A Survey and Analysis of Early Music Consumers in Texas
Authors:   , Emanski Julianna
Published: February 2025

Texas has a rich tradition of Early Music ensembles that dates back to 1969. However, there is little reliable information based on statistical data collection and analysis concerning Texas Early Music consumers. Little is known about why they attend Early Music performances or other important factors that affect the Early Music industry. Through the use of an extensive survey and accompanying statistical analysis, this study answers many questions regarding Early Music consumers in the State of Texas. This study collected demographic and psychographic data in January 2020 about the Early Music concert-going public in three major Texas cities - Dallas, Austin, and Houston. Other factors were identified in two primary areas: audience characteristics and ticket pricing practices.

Cross-Cultural Adult Attachment, Assertiveness, Self-Conscious Emotions, and Psychological Symptoms
Authors:   , Jin Ling
Published: February 2025

Although the overall quantity of international research has increased, existent studies tend to adopt an instrument developed in one culture to use in the other, leading to measurement bias. In addition, previous cross-cultural research mainly focuses on comparisons between collectivist and individualistic backgrounds (e.g., American vs. Chinese) without considering the similarities and differences within the collectivist societies (e.g., China vs. Mexico). This dissertation project has two purposes, with Study 1 aiming to examine measurement equivalence of two widely used instruments while Study 2 investigating if an attachment-based two-serial mediation model remained constant among three cross-cultural samples collected from the US, Mexico, and China. A total of 1211 participants, including 360 American university students, 441 Mexican students, and 410 Chinese students participated in the study. Differential item functioning (DIF) in lordif package in R and structural equation modeling (SEM) in Mplus 8.1 were adopted for Study 1 and 2, respectively. The results of Study 1 indicated the proposed instruments were culturally invariant in English, Spanish, and Chinese with some modifications. Study 2 showed that assertiveness/self-conscious emotions mediated the association between adult attachment and depression/aggression only in the US group. However, the two-serial mediation model in which the link between adult attachment and depression/aggression via assertiveness to self-conscious emotions was supported in Mexican and Chinese groups, not in the US group. Findings from these two cross-cultural adult attachment studies provide additional insights for future attachment research and useful implications for psychologists working with diverse individuals from the US, Mexico, and China.
Clementi the Scientist: Contemporary Reception of His Symphonies
Authors:   , Asber Joyce
Published: February 2025

Muzio Clementi's symphonies were first performed in London between 1786 and 1796. After an extended hiatus from 1796 to 1813, his symphonic works appeared on programs again from 1813 to 1824. Clementi's career as a symphonist corresponds closely with trends in London's concert life. The reception of Clementi's symphonies during his lifetime has frequently been misinterpreted by scholars who oversimplify the use of "science" in musical discourse of the day and fail to consider the positive connotations of this adjective, so frequently applied to Clementi. Musical discourse at the time addressed the science and art of music emphasizing a composition, or its composer's, science, harmony, effects, genius, and the audience's response. Though an unstated ideal, reviews evince a preference for balancing scientific and artistic display. Reviews of Clementi's symphonies suggest he initially struggled to balance the technical and artistic qualities of his compositions but succeeded, according to reviews, in finally doing so in 1796. After his early efforts, Clementi was consistently praised as worthy to stand among the current and most prestigious composers of the continent: Haydn and Mozart initially, and Beethoven and Rossini later.
Does Quality Management Practice Influence Performance in the Healthcare Industry?
Authors:   , Xie Heng
Published: February 2025

This research examines the relationship between quality management (QM) practices and performance in the healthcare industry via the conduct of three studies. The results of this research contribute both to advancing QM theory as well as in developing a unique text mining method that is illustrated by examining QM in the healthcare industry. Essay 1 explains the relationship between operational performance and QM practices in the healthcare industry. This study analyzed the findings from the literature using meta-analysis. We applied confirmatory semantic analysis (CSA) to examine the Baldrige winners' applications. Essay 2 examines the benefits associated with an effective QM program in the healthcare industry. This study addressed the research question about how effective QM practice results in improved hospital performance. This study compares the performance of Baldrige Award-winning hospitals with matching hospitals, state average, and national average. The results show that the Baldrige Award can lead to an increase in patient satisfaction in certain periods. Essay 3 discusses the contribution of an online clinic appointment system (OCAS) to QM practices. An enhanced trust model was built on understanding the mechanism of patients' trust formation in the OCAS. Understanding the determinants related to patients' trust and willingness to use OCAS can provide valuable guidance for medical institutions to establish health information technology-based services in the quality service improvement programs. This research has three significant contributions. First, this research analyzes the role of QM practices in the healthcare industry. Second, this research attempts to develop a unique text mining method. Third, this research provides a validated trust model and contributes to the body of research on the trust of healthcare information technology.
Kriging Methods to Exploit Spatial Correlations of EEG Signals for Fast and Accurate Seizure Detection in the IoMT
Authors:   , Olokodana Ibrahim Latunde
Published: February 2025

Epileptic seizure presents a formidable threat to the life of its sufferers, leaving them unconscious within seconds of its onset. Having a mortality rate that is at least twice that of the general population, it is a true cause for concern which has gained ample attention from various research communities. About 800 million people in the world will have at least one seizure experience in their lifespan. Injuries sustained during a seizure crisis are one of the leading causes of death in epilepsy. These can be prevented by an early detection of seizure accompanied by a timely intervention mechanism. The research presented in this dissertation explores Kriging methods to exploit spatial correlations of electroencephalogram (EEG) Signals from the brain, for fast and accurate seizure detection in the Internet of Medical Things (IoMT) using edge computing paradigms, by modeling the brain as a three-dimensional spatial object, similar to a geographical panorama. This dissertation proposes basic, hierarchical and distributed Kriging models, with a deep neural network (DNN) wrapper in some instances. Experimental results from the models are highly promising for real-time seizure detection, with excellent performance in seizure detection latency and training time, as well as accuracy, sensitivity and specificity which compare well with other notable seizure detection research projects.
Twitter and the Affordance of Public Agenda-Setting: A Case Study of #MarchForOurLives
Authors:   , Chong Mi Young
Published: February 2025

In the traditional agenda-setting theory, the agenda-setters were the news media and the public has a minimal role in the process of agenda-setting, which makes the public a passive receiver located at the bottom in the top-down agenda-setting dynamics. This study claims that with the development of Information communication technologies, primarily social media, the networked public may be able to set their own agendas through connective actions, outside the influence of the news media agenda. There is little empirical research focused on development and dynamics of public agenda-setting through social media platforms. Understanding the development and dynamics of public agenda-setting may be key to accounting for and overcoming conflicting findings in previous reverse agenda-setting research. This study examined the public agenda-setting dynamics through a case of gun violence prevention activism Twitter network, the #MarchForOurLives Twitter network. This study determined that the agenda setters of the #MarchForOurLives Twitter network are the key Never Again MSD student leaders and the March For Our Lives. The weekly reflected important events and issues and the identified topics were highly co-related with the themes examined in the tweets created by the agenda setters. The amplifiers comprised the vast majority of the tweets. The advocates and the supporters consisted of 0.44% and 4.43% respectively. The tweets made by the agenda setters accounted for 0.03%. The young activists and the like-minded and participatory public could continuously make changes taking advantage of technologies, and they could be the hope in the current and future society.
Sounds Themselves: Intersections of Serialism and Musique Concrète in Karlheinz Stockhausen's "Elektronische Studie I"
Authors:   , Huff David
Published: February 2025

In the summer of 1953, Karlheinz Stockhausen began composing his first piece of elektronische Musik at the Westdeutscher Rundfunk Studio for Electronic Music in Cologne. Up to that point, Stockhausen's only experience with electroacoustic music was his time spent at the Radiodiffusion-Télévision Française the previous year, where he assisted Pierre Schaeffer and composed a piece of musique concrète. An early case study in the marriage of serial aesthetics and electroacoustic techniques, Studie I is a rigorously organized work that reflects Stockhausen's compositional philosophy of a unified structural principle in which all musical materials and parametric values are generated by and arranged according to a single governing series. In spite of this meticulously wrought serial structure, Studie I displays features that are the consequences of the realities of electronic sound production either imposing on the sonic result, or altering the compositional plan entirely. I use a three-part approach to my analysis of Studie I by examining Stockhausen's serial system, the electroacoustic studio techniques in use in 1953, and the original recorded realization through spectrographic analysis. Using this methodology, I expose the blurring of the supposed divide between elektronische Musik and musique concrète by exploring the features that lie between the serial plan and the technical processes Stockhausen used to realize Studie I.
High Temperature Sliding Wear Behavior and Mechanisms of Cold-Sprayed Ti and Ti-TiC Composites
Authors:   , Koricherla Manindra Varma
Published: February 2025

Ti and Ti-based alloys are used in many aerospace and automotive components due to their high strength-to-weight ratio and corrosion resistance. However, room and elevated temperature wear resistance remain an issue, thus requiring some form of secondary hard phase, e.g., refractory carbides and oxides, as well as solid lubrication to mitigate wear. In this study, Ti-TiC (14, 24 and 35 vol% TiC) composite coatings were deposited on mild steel substrates using cold spray with comparisons made to baseline cold-sprayed Ti. The dry sliding friction and wear behavior were studied from 25°C to 575°C and during thermal cycling in this temperature range. While the room temperature friction coefficient of all the coatings remained relatively constant at ~0.5, the wear rate continually decreased from ~1x10-3 to ~2x10-5 mm3/N-m with increasing the TiC loading. Raman spectroscopy measurements determined that the same TiO2 tribochemical phases (rutile and anatase) were present on the room temperature sliding wear surfaces, thus responsible for similar friction coefficients. With increasing sliding temperatures to 575°C, the Ti-35%TiC composite coating exhibited the best overall tribological behavior, i.e., the friction coefficient decreased to ~0.3 along with a negative wear rate of -6.6x10-5 mm3/N-m (material gain on the wear track was recorded due to oxidation and transfer from the counterface). These friction and wear reductions were determined to be due to the formation of stable, low interfacial shear strength oxide glaze layers on the wear surfaces, composed of TiO2, WO3, and CoWO4 (transfer from WC-Co counterface). In addition, self-adaptive friction behavior was observed during thermal cycling as a result of the microstructural and tribochemical differences in the tribolayers.
Contributions to Geometry and Graph Theory
Authors:   , Schuerger Houston S
Published: February 2025

In geometry we will consider n-dimensional generalizations of the Power of a Point Theorem and of Pascal's Hexagon Theorem. In generalizing the Power of a Point Theorem, we will consider collections of cones determined by the intersections of an (n-1)-sphere and a pair of hyperplanes. We will then use these constructions to produce an n-dimensional generalization of Pascal's Hexagon Theorem, a classical plane geometry result which states that "Given a hexagon inscribed in a conic section, the three pairs of continuations of opposite sides meet on a straight line." Our generalization of this theorem will consider a pair of n-simplices intersecting an (n-1)-sphere, and will conclude with the intersections of corresponding faces lying in a hyperplane. In graph theory we will explore the interaction between zero forcing and cut-sets. The color change rule which lies at the center of zero forcing says "Suppose that each of the vertices of a graph are colored either blue or white. If u is a blue vertex and v is its only white neighbor, then u can force v to change to blue." The concept of zero forcing was introduced by the AIM Minimum Rank - Special Graphs Work Group in 2007 as a way of determining bounds on the minimum rank of graphs. Later, Darren Row established results concerning the zero forcing numbers of graphs with a cut-vertex. We will extend his work by considering graphs with arbitrarily large cut-sets, and the collections of components they yield, to determine results for the zero forcing numbers of these graphs.
Examining Human Information Behavior on Social Media: Introducing the Concept of Social Noise
Authors:   , Zimmerman Tara D
Published: February 2025

Social media information behavior is increasingly critical, impacting not only individuals and groups but the beliefs, values, and direction of society and culture. The purpose of this study was to investigate how persistent observation by members of the online network influences social media users' information behavior, resulting in the phenomenon of social noise. Data analytics, including LDA, LSA, and clustering methodologies, were performed but could not provide information about the users' motivations. Using an ethnographic approach, participant observations and interviews were conducted with Facebook users as they interacted with informational posts, and the data collected was coded using a recursive method. Four key constructs of social noise were identified, and sub-codes were assigned within each construct as patterns emerged, providing insight into the different facets of social noise. Additionally, in most instances more than one of the four constructs were present, layering their influence on the information behavior. Based on these findings, social media users are not always interacting with information based on true personal beliefs or desires; instead, concerns surrounding their personal image, relationships with others, core beliefs, and online conflict are influencing their observable information behavior. The results of this exploratory study provide a basis to further develop the social noise model. Qualitative data provides insight into the thinking and motivations behind social media users' observable information behavior, specifically in the areas of cultural agency, relationship management, image curation, and conflict engagement.
Students' Preferences for Mobile Technology to Learn Foreign Languages
Authors:   , Hanna Atheer H
Published: February 2025

The current study was conducted with foreign language students enrolled in the summer course at Middlebury Institute of International Studies (MIIS), an intense foreign language program. The study measured and analyzed students' preferences toward mobile applications for learning a foreign language. Survey questionnaires were used to collect data on students' preferences of mobile delivery modes for learning a foreign language. The research design deployed was single-case design at two points-in-time, called repeated measures design in the t-test statistics, where effects-over-time of treatment (i.e., using a technological device) were tracked. The effects-over-time of using a mobile device for learning foreign language skills were significant and the magnitude of differences in students' attitudes between Weeks 2 and 8 was also significant. Students must have felt that their performance had changed at Week 8 and that using a smartphone could have been the difference. The structure and the research methodology of having null hypotheses that are tested statistically are both clear enough to provide a template for a replication of the study with a different sample. The statistical tests used by this study can be replicated with different research problems or a different audience.
Stimulus Control Effects of Changes in Schedules of Reinforcement
Authors:   , Abdel-Jalil Awab
Published: February 2025

Sometimes, changes in consequences are accompanied by a clear stimulus change explicitly arranged by the experimenter. Other times when new consequences are in effect, there is little or no accompanying stimulus change explicitly arranged by the experimenter. These differences can be seen in the laboratory as multiple (signaled) schedules and mixed (unsignaled) schedules. The current study used college students and a single-subject design to examine the effects of introducing signaled and unsignaled schedules, and the transitions between them. In one phase, a card was flipped from purple to white every time the schedule was switched from VR-3 to FT-10. In another phase, the schedule still changed periodically, but the card always remained on the purple side. Results showed that the participants' responding was controlled by the schedule of reinforcement, by the color of the card, or both. These results suggest that changes in patterns of reinforcement lead to changes in stimulus control. In addition, the stimulus control for a behavior can come from several different sources. During teaching, it may facilitate the development of stimulus control to change the environment when a new behavior is required.
Factor Retention Strategies with Ordinal Variables in Exploratory Factor Analysis: A Simulation
Authors:   , Fagan Marcus A.
Published: February 2025

Previous research has individually assessed parallel analysis and minimum average partial for factor retention in exploratory factor analysis using ordinal variables. The current study is a comprehensive simulation study including the manipulation of eight conditions (type of correlation matrix, sample size, number of variables per factor, number of factors, factor correlation, skewness, factor loadings, and number of response categories), and three types of retention methods (minimum average partial, parallel analysis, and empirical Kaiser criterion) resulting in a 2 × 2 × 2 × 2 × 2 × 3 × 3 × 4 × 5 design that totals to 5,760 condition combinations tested over 1,000 replications each. Results show that each retention method performed worse when utilizing polychoric correlation matrices. Moreover, minimum average partials are quite sensitive to factor loadings and overall perform poorly compared to parallel analysis and empirical Kaiser criterion. Empirical Kaiser criterion performed almost identical to parallel analysis in normally distributed data; however, performed much worse under highly skewed conditions. Based on these findings, it is recommended to use parallel analysis utilizing principal components analysis with a Pearson correlation matrix to determine the number of factors to retain when dealing with ordinal data.
Spiritually-Oriented Expressive Writing and Positive Psychological Outcomes Following a Natural Disaster
Authors:   , Mosher David K
Published: February 2025

Many religious/spiritual (R/S) individuals receive meaning from R/S and utilize R/S to help them cope with stressful life events. However, natural disasters can disrupt the R/S meaning-making process (e.g., positive R/S coping strategies) because natural disasters can elicit cognitive dissonance between one's core R/S beliefs and personal disaster experience. R/S individuals suffering from a disaster experience could benefit from interventions that allow them to process their R/S experiences. The purpose of this dissertation is to fill a gap in the literature by exploring the effectiveness of a spiritually-oriented expressive writing intervention on positive psychological outcomes (e.g., meaning in life, satisfaction with life) in 132 R/S individuals that have experienced a natural disaster (i.e., survivors of the 2016 Baton Rouge, Louisiana flood). Quantitative results indicated the spiritually-oriented intervention was effective in promoting increased meaning in life but not life satisfaction. Survivors with lower pre-intervention positive attitudes toward God evidenced the strongest positive impact on their meaning in life. Qualitative analyses, using the constant comparative method from Corbin and Strauss's grounded theory approach, revealed six themes in the experimental group's written responses: (a) R/S growth, (b) R/S struggle, (c) R/S cognitive dissonance, (d) R/S reappraisals, (e) R/S proximity-seeking, and (f) spiritual support and cohesion. I conclude by discussing limitation, areas for future research, and implications for counseling.
Military Religio: Caesar's Religiosity Vindicated by Warfare
Authors:   , Adkins Austin L
Published: February 2025

Gaius Julius Caesar remains one of the most studied characters of antiquity. His personality, political career, and military campaigns have garnered numerous scholarly treatments, as have his alleged aspirations to monarchy and divinity. However, comparatively little detailed work has been done to examine his own personal religiosity and even less attention has been paid to his religion in the context of his military conquests. I argue that Caesar has wrongly been deemed irreligious or skeptical and that his conduct while on campaign demonstrates that he was a religious man. Within the Roman system of religion, ritual participation was more important than faith or belief. Caesar pragmatically manipulated the Romans' flexible religious framework to secure military advantage almost entirely within the accepted bounds of religious conduct. If strict observance of ritual was the measure of Roman religiosity, then Caesar exceeded the religious expectations of his rank and office. The evidence reveals that he was an exemplar of Roman religio throughout both the Gallic Wars (58-51BC) and the subsequent Civil Wars (49-45BC).
Effect of Trauma-Related Stress during Acute Alcohol Intoxication on Driving-Related Risky Decision-Making
Authors:   , Kearns Nathan T
Published: February 2025

Alcohol-related motor vehicle crashes are a major preventable cause of death in the United States. One potential factor that may modulate the influence of alcohol intoxication on driving-related decision-making is posttraumatic stress. The current study evaluated the influence of induction of acute trauma-related stress (via script-driven imagery) during alcohol intoxication (.06% BrAC) on driving-related risky decision-making – willingness to drive, driving-related decision-making (i.e., attempted red light runs), and driving-related reaction time (i.e., braking latency) – among 56 trauma-exposed (currently symptomatic) adult drinkers from the community (M = 25.32; 46.4% female). Results indicated that trauma-related stress may exacerbate willingness to drive during a state of acute alcohol intoxication, but, alternatively, may have only a minimal-to-moderate effect on performance-based, driving-related decision-making (i.e., red light runs), and a potentially mitigating impact on driving-related reaction time (i.e., braking latency) under the influence of alcohol. Generally, results suggest that trauma-related stress may differentially impact varying aspects of driving-related risky decision-making, above and beyond the influence of alcohol. Implications for theoretical modeling for driving-related decision-making during acute intoxication and for the advancement of education and intervention efforts, as well as suggestions for future directions, including methodological and procedural improvements, are discussed.
Implications of Performance-Based Contracting on Logistics and Supply Chain Management: A Multi-Method Approach
Authors:   , Celik Hasan
Published: February 2025

Performance-based contracting (PBC) redefines the relationships between suppliers and buyers and differs from traditional contracting approaches with its reward/payment scheme, emphasis on the performance outcomes, increased supplier autonomy, and transfer of risk and responsibilities to suppliers. Given the 70% of life cycle costs of products/systems reside in sustainment, PBC has led to substantial improvements in availability, maintainability, reliability, and thus total cost of ownership of systems/products. Though PBC has changed the way of doing business and its presence has increased across multiple industry, private and public sectors, for profit and not-for-profit, its implications on various aspects of logistics and supply chain management have been understudied. It is important to explore and establish evidence regarding these implications through academic rigor. Therefore, this three-essay dissertation aims to give some insight regarding structural and behavioral implications of PBC using a multi-method approach. Specifically, it (1) explores the relationship between PBC and supply chain resilience (SCRES), (2) examines the supplier goal commitment (i.e., motivation) in PBC, (3) proposes a mathematical model to find optimal contract length, periodic contract price and investment that concurrently maximizing supplier profit and satisfying buyer requirements. This dissertation offers theoretical and managerial contributions as well.
Creating a Campus Culture of Academic Integrity in the Community College: Exploring the Relationship between Faculty Perception of Institutional Communication and the Perception of a Culture of Academic Integrity
Authors:   , Haduch Brett Thomas
Published: February 2025

The purpose of this research was to determine what preferences exist for full- and part-time community college faculty for institutional communication and if institutional communication predicts faculty perception of an academic integrity culture. The sample is nationally representative, consisting of institutional representation from five of the six accreditation regions nationally, a relativity equal distribution of three Carnegie Classifications (higher career & technical, high transfer, and mixed transfer/career & technical) and three Census Bureau defined population areas (urbanized area, urban cluster, and rural area). The survey, completed by 328 faculty from eight community colleges, was a modified version of three widely used instruments: the International Center for Academic Integrity Academic Integrity Faculty Survey, the International Communication Association Audit, and the Organizational Communication Development Audit Questionnaire. Chi-square, independent samples t-test, and hierarchical regression analysis were each used to explore the relationship between the perception of communication, channels of communication, and perceived culture of academic integrity. The results suggest that face-to-face and electronic communication channels are both preferred channels of communication among full- and part-time faculty and that the communication through these two channels is predictive and interactional. In collaboration with a positive perception of communication, both worked to predict a perceived culture of academic integrity.
After-Sales Service Contracting for Excellence in Life-Cycle Cost Management: Numerical Experiments and Systematic Review of Analytical Models
Authors:   , Küçük Carullah Yavuz
Published: February 2025

This research adds to the literature and provides insight to practice via three essays that increase understanding about the applications and consequences of the two new approaches to the after-sales service governance: warranty contract and performance-based contracts. First, we attempted to enhance our knowledge of the modeling of the after-sales service process. In the first essay, the research papers with analytical models of after-sales services to present current trends, issues, and future research directions in the literature are classified. In the second essay, the effect of the warranty contract on the supplier's product quality improvement efforts in the context of capital goods is examined. Three sets of optimization models reveal that the existence of a warranty improves product quality. In the third essay, the performance-based contract is examined in the context of the warranty contract. The numerical experimentations conducted demonstrate that the performance-based contract is superior to the warranty contract in terms of the supplier's product quality efforts and the customer's total cost of after-sales services. The alignment of incentives based on the product performance tackles the issues presented in the traditional after-sales service contracting. Collectively, the three studies presented in this research expand our understanding of after-sales service contracts. Thus, the research presents managerial implications and adds to the existing body of knowledge in after-sales service research.
The Impostor Phenomenon among Female High School Principals: A Mixed Methods Study

Published: February 2025

The purpose of this sequential mixed-methods study was to explore the feelings, thoughts, critical incidents, and coping mechanisms of female high school principals and their experiences with the impostor phenomenon. A hierarchical multiple regression revealed that none of the demographic factors such as number of years as a head high school principal, age, percentage of female high school principals in the district, race/ethnicity, marital status, mentorship status, and community type, were statistically significant predictors of the varying levels of the impostor phenomenon. Eighteen female principals who represented an array of backgrounds and impostor phenomenon experiences were subsequently interviewed. The interviews were evaluated using interpretative phenomenological analysis. Seven themes, including several subthemes, emerged from the data. The themes were (1) childhood socialization, including the subthemes of gender roles, familial support, and early experiences of exclusion; (2) transitional uncertainty, including hiring self-doubt, school politics, and pressure to turn around a school; (3) the principalship, including relational leadership, constant pressure, and loneliness of the position; (4) critical incidents of the impostor phenomenon, including the subthemes of lack of experience, external criticism, and self-doubt; (5) gender issues, including a male dominated position, emotional capacity, and physical appearance, (6) coping strategies for the impostor phenomenon, including mentorship and peer support, family support, and self-talk; and (7) combating the impostor phenomenon, including proven success, dismissing criticism through confidence, overcoming controversy and religion or spirituality. The results of this study suggest that mentorship, role models, familial support, and developing self-confidence can help alleviate the negative effects of the impostor phenomenon. It is recommended that educational leadership preparation programs educate students about the impostor phenomenon in an effort to normalize how they view themselves at various transitional phases of their career while offering supports to help them combat potential feelings of self-doubt that may arise as they progress through their careers.
Development and Disruption of Collateral Behavior and DRL Performances: A PORTL Exploration
Authors:   , Herzog Leah
Published: February 2025

One schedule of reinforcement that is used to decrease the rate of a target behavior is differential reinforcement of low rates (DRL). During this schedule, reinforcement is delivered for a target response if it occurs after a certain amount of time has passed since the last instance of this target response. The current study used a table-top game called PORTL and college student participants to investigate how collateral patterns develop and are disrupted during DRL schedules. After the participant developed a collateral pattern of behaviors with the objects, the researcher removed one of the objects that was part of the pattern and waited for a new pattern of behaviors to develop. Once the participant developed a new collateral pattern, the researcher removed a second object. This continued until there was only one object present. Results showed that the rate of reinforcement decreased following the removal of each object, then slowly increased as a new pattern developed.
User Privacy Perception and Concerns Regarding the Use of Cloud-Based Assistants

Cloud-based assistants like the Google Home and the Amazon Alexa have become ubiquitous in our homes. Users can simply communicate with the devices using a smartphone application. There are privacy concerns associated with cloud-based assistants. For example, users do not know what type of information is being sent to the device manufacturer, if the device is stealthily listening to conversations, data retention, or who else has access to the data. Privacy is about perception. The goal of this study is to determine user privacy concerns regarding cloud-based assistants by adopting a quantitative research method. The study used a privacy decision framework that lists three core components, which are technology controls, understanding user privacy preference, and government regulations. The research used Dervin's sensemaking model to describe users' privacy perception using the privacy decision framework and improved on a privacy perception survey instrument from previous dissertations. An understanding of user privacy concerns with cloud-based assistants is required to provide a comprehensive privacy guidance to stakeholders. The significance of this study is in the identification of the privacy perception of users of cloud-based assistants and the extent to which the components of the theoretical framework can impact user privacy perception. The results of this study serve as a guide for device manufacturers and other stakeholders in prioritizing privacy design decisions.
Mariachismo: Music, Machismo, and Mexicanidad
Authors:   , Torres José R.
Published: February 2025

One of the most recognized icons of Mexico is the mariachi moderno tradition, which in the global popular imaginary, is associated with nostalgic, humorous, and emotional songs of love, heartache, death, drinking, and place. Inseparably fused to tequila and the historic charro figure, mariachi moderno completes a symbolic trinity of hetero-nationalist culture, conveyed within a popular imaginary of authentic mexicanidad (Mexican-ness). For mariachis and aficionados in Mexico, performative hypermasculine machismo acts as a perceptual baseline, structuring modes of feeling that signify an experience of authentic nationalist musicality This process is musically constructed in an incorporation of bodily movement, instruments, sound timbres, and symbolic clothing, simultaneously gestured with a heavy male-accent fusing an experience that feels genuinely Mexican. This reflexive signification is a consequence of the lived experience, shared dispositions, and competencies learned in the habitus, constituting real and imagined notions of hetero-nationalist culture. I refer to this musical semiosis as mariachismo, a neologism describing an intersubjective experience of machismo-infused mariachi subjectivity, ritualized through repeated gestures of sound, lyric, and corporeality. The semiotic power of mariachismo is most potent for subjects enculturated to Mexico's hetero-nationalist culture, shaped by popular imaginaries operationalizing gender and mexicanidad, connecting the two, making them feel unquestioned, natural, and unmediated. The ontology of mariachismo, is in part revealed through an analysis of metaphors used by practitioners and aficionados to describe mariachi's musical techniques and social practices. These metaphors index an archive of embodied knowledge, a lived experience where hypermasculine subjectivity is reified and other forms of gendered performativity, including femininity and non-hetero subjectivities, are marginalized or purposefully subverted. Employing ethnomusicological analysis and building on concepts of habitus, performativity, and musical semiotics, this dissertation illustrates how mariachismo aesthetically enacts sonic-somatic gestures, enhanced by fetishized clothing, and construed within a symbolic music practice, all of which ritualize a perceptual experience of authentic mariachi musicality.
