Romantyzm zracjonalizowany. „Rozmowa duchów” Placyda Jankowskiego
Authors: Chłopek Patryk
Published: December 2023

Poczytny humorysta lat czterdziestych XIX wieku – John of Dycalp – szybko zdobył popularność dzięki swojemu dowcipowi i oryginalnej formie literackiej. Wydane w 1841 roku Pisma przedślubne i przedsplinowe, którymi pisarz niejako powtórnie debiutował, zyskały wiele pozytywnych recenzji, a ich autorzy wyrażali nadzieje na rozwój talentu artysty. W ciągu najbliższych paru lat skrywający się pod pseudonimem Placyd Jankowski miał wydać kilkanaście różnych dzieł, które bardziej lub mniej odpowiadały gustom czytelników. Rozmowa duchów otwiera pierwszy tom Pism, które przyspieszyły literacką karierę Jankowskiego. Opracowanie utworu ma na celu przypomnienie twórczości pisarza, jest także swojego rodzaju zapowiedzią powstającej pełnej edycji Pism przedślubnych i przedsplinowych.

Intergenerational Differences in Barriers that Impede Mental Health Service Use among Latinos
Authors:   , Escobar-Galvez Irene
Published: December 2023

Research has extensively documented the mental health disparities that exist for ethnic and racial minorities living in the United States. With respect to Latinos, such disparities are marked by less access to care and poorer quality of mental health treatment. Studies on Latino mental health have found differences in mental health service utilization among ethnic subgroups and among different generations of Latinos. However, empirical data examining specific attitudes and barriers to mental health treatment among different generations of Latinos are limited. This study explored the relationships between Latino generational status, mental health service utilization, psychological distress, and barriers to mental health treatment. An online survey (N = 218) included samples of first-generation (n = 67), second-generation (n = 86), and third-generation or beyond Latinos (n = 65). Results indicated first-generation Latinos had the lowest rate of mental health service utilization and reported greater linguistic and structural knowledge barriers, however, they had lower perceived social stigma of mental health services when age at migration was considered. Implications of these findings for research, mental health service providers and mental health policy are discussed.
Differences in Socio-Cognitive Processes among Individuals Exhibiting Characteristics of Grandiose and Vulnerable Narcissism: A Multimethod Approach
Authors:   , Sanders Courtney
Published: December 2023

This study explored how well specific socio-cognitive processes (i.e., interpersonal problems, empathy, hostile attributional biases, envy/jealousy) predicted the manifestations of both grandiose and vulnerable narcissism. Additionally, we explored the impact of both forms of narcissism on the presence of maladaptive social behaviors (i.e., the perpetration of psychological abuse). We found that domineering interpersonal behaviors and a propensity to fantasize predicted significant unique variance in grandiose narcissism; envy of others, hostile attributional biases, and a propensity to fantasize predicted significant unique variance in vulnerable narcissism. Additionally, while domineering interpersonal behaviors and hostile attributional biases predicted significant variance in psychological abuse perpetration, only vulnerable narcissism added significant unique variance to its regression model. Lastly, only domineering interpersonal behaviors, envy of others, and hostile attributional biases predicted significant unique variance in psychological abuse victimization; narcissism was nonsignificant. The results of our study will contribute to an increased understanding of the nature of both grandiose and vulnerable narcissism and the impacts these personality styles have on an individual's ability to function effectively in interpersonal relationships.
Developmental Effects of a Non-Dioxin-Like Polychlorinated Biphenyl Mixture on Zebrafish (Danio rerio)
Authors:   , Green Corey
Published: December 2023

PCBs are synthetic organic compounds known for their toxicity to many organisms and are notorious for having large discrepancies between measured and nominal concentrations. Historically thought to be less toxic, non-dioxin-like (NDL) PCBs represent the majority of congeners and are capable of eliciting neurotoxic effects. NDL-PCBs remain understudied, including their effects on aquatic organisms. In the first study, I collected extensive chemistry data and data on neurobehavioral and cardiac endpoints to test the acute effects of exposure to an NDL-PCB mixture on early life stage zebrafish. Neurobehavioral effects observed in the first study indicated a potential for longer term behavioral effects in these fish. In the second study, I collected data on feeding, social, and memory behavior of zebrafish at time points beyond the acute exposure from the first study. Acute and longer-term behavioral endpoints in the first and second studies demonstrated effects from PCB exposure but did not indicate mechanisms. In the third study, I collected untargeted and targeted metabolomic data on amino acid, sugar, anionic compound, and neurotransmitter profiles to determine the specific pathways affected by exposure to an NDL-PCB mixture. These combined data from these studies provide a unique insight into the chemical profile of an NDL-PCB mixture in biological applications and synthesize acute, longer-term, and mechanistic effects on developing zebrafish. These data fully illustrate an adverse outcome pathway from toxicokinetic to population level effects.
"An Encountered Moment"
Authors:   , Thomas Aaron Mahlon
Published: December 2023

This MFA graduate thesis explores the intersection of therapeutic photography, generational trauma, and Christian spirituality in promoting spiritual healing in disabled veterans diagnosed with post-traumatic stress disorder (PTSD). Drawing from personal experience, rigorous biblical training, and extensive research, I argue that incorporating faith-based practices and beliefs can complement existing PTSD support and enhance spiritual and mental well-being. Through the lens of generational trauma, the thesis analyzes the complex interplay between individual and collective trauma. It posits that the healing process is intrinsically linked to the restoration of the individual and community. I present a framework for therapeutic photography that incorporates Christian spiritual principles and offers practical guidelines for implementation in conjunction with therapeutic photography. The thesis concludes with a call to action for faith-based communities, mental health practitioners, and policymakers to recognize and address the spiritual and artistic therapeutic needs of disabled veterans with PTSD.
Spectral, Electrochemical, and Photochemical Characterization of Donor-Acceptor Supramolecular Systems
Authors:   , Liyanage Anuradha Vidyani
Published: December 2023

This dissertation research work focuses on the investigation of novel donor-acceptor systems elucidating their photochemical properties, anion binding, and their potential application in the development of artificial photosynthetic systems. The explored systems are based on oxoporphyrinogen (OxPs), porphyrins, fullerene, and boron dipyrromethene (BODIPY) based donor-acceptor systems. The photochemical properties of novel molecular systems were elucidated using UV-vis spectroscopy, fluorescence spectroscopy, electrochemical methods, computational calculations, and ultrafast transient absorption spectroscopy. A novel BODIPY-oxoporphyrinogen dyad which is able to bind with fluoride anion promoting the excited state ultrafast electron and energy transfer events mimicking the primary events in natural photosynthesis was introduced. Further, self-assembly of supramolecular complexes based on oxoporphyrinogens, fullerene, and different zinc porphyrin dimers was explored. The formed self-assembled complexes have shown photoinduced electron transfer. A novel push-pull supramolecular construct based on the spiro-locked N-heterocycle-fused zinc porphyrin was studied. The excited state charge separation and stabilization of this push-pull system was enhanced by the complexation with fluoride anion. Also, the effect of BODIPY functionalization and linkers on the electron transfer properties of a series of carbazole–BODIPY and phenothiazine-BODIPY dyads were investigated. These findings are important to develop advanced and efficient BODIPY-based donor-acceptor systems for efficient light harvesting applications. The entire study aims to expand our understanding of these systems and contribute towards the advancement of sustainable energy technologies.
Secondary Production of Dragonflies: Comparing Ecosystem Function of Ponds within an Urban Landscape in North Central Texas
Authors:   , Stallings Gillian Carol
Published: December 2023

The change of land use to include more urban areas is considered one of the main threats to biodiversity worldwide. Urban stormwater retention ponds have been built to collect storm runoff intensified by the increase in impervious surfaces. Although subject to environmental pressures like habitat degradation and pollution, these stormwater retention ponds are diversity hotspots by providing habitat for several aquatic and semi-aquatic species, including dragonflies. Previous research in Denton, Texas, has demonstrated that urban stormwater retention ponds support high taxa richness of adult dragonflies, but not for the aquatic nymphs. The current study builds on what we have seen by focusing on the immature aquatic stage as nymphs using secondary production of dominant dragonfly taxa and community structure to compare ecosystem function in three ponds with differing intensities of land use. Comparing communities and secondary production resulted in specific conductivity, dissolved oxygen, complex vegetation, and abundance explaining the differences between dragonfly communities. Secondary production was dependent on abundance which followed the intensity of urban land use surrounding the pond. This study supports that urban land use does have an effect on the functioning of the ponds and shows the importance of studying the communities over a year to get a clearer picture of what is happening in the ponds.

Authors:   , Kairu Caroline Wambui
Published: December 2023

The study explores the effectiveness of multimodality teaching using the 4MAT Model. A meta-analysis was conducted with empirical studies on instruction via multimodality teaching in preschool, K-12, and higher education. The studies in the meta-analysis involved an experimental and control group. The control group received traditional teaching lessons, and the experimental group received multimodality teaching. A text analysis was conducted to examine the trends in the advantages of the 4MAT model versus traditional methods. The literature review analyzed the cognitive theory of multimedia learning, advances in multimedia teaching effectiveness assessment, transforming traditional teaching through the 4MAT model, 4MAT model and learning, the importance of multimodality teaching, the origin of multimodality teaching, the 4MAT model, and multimodality teaching and student achievement. This research aimed to determine a better understanding and increase learning achievement by using the 4MAT model versus traditional teaching methods.
Investigation of Existing and New Human Resource Practices on Public Health Employee Retention during the COVID-19 Pandemic in Saudi Arabia
Authors:   , Alattas Mohsen Mohammad A
Published: December 2023

This research investigates existing and new HR practices that have impacted public health employee retention in Saudi Arabia during the COVID-19 pandemic. It builds on social support theory and social exchange theory to better understand the relationships between HR practices and retention, and uses quantitative methods to examine the hypotheses based on a conceptual framework. While OLS regression is employed to analyze the relationships between HR practices and retention, path analysis (bootstrapping) is used to examine the mediator variable. Based on 417 valid questionnaires distributed to public health employees in Saudi Arabia's central, western, and eastern regions, the analysis illustrates that while training and emphasis on work-life-balance as existing HR practices had a positive effect on retention, social support (supervisory support) and promotion of mental well-being as new HR practices also had a positive effect on retention during the COVID-19 pandemic. However, the hypothesis that compensation and occupational health and safety would improve retention was not supported. These results indicate that financial benefits and providing safety materials did not lead to employee retention. Meanwhile, safety training programs, psychosocial support, and promotion of well-being have been essential HR practices during the pandemic. Regarding the mediation hypotheses, interestingly, the results show that organizational commitment has mediated relationships between safety training and mental (psychological) well-being on one hand and public health retention on the other during the pandemic.
Views from the Beach: Spectator Positions and the American International Pictures Beach Party Films
Authors:   , Leavy Mark
Published: December 2023

The American International Pictures (AIP) Beach Party Films were a major American cultural phenomenon in the early 1960s and continue to play a significant role in the American cultural imagination. The AIP Beach Party Films, despite their popularity and influence, have been largely ignored by academia and a thorough academic examination has yet to be written. This thesis attempts to change such an academic precedent. At first glance, the Beach Party Films are frivolous and chaotic (perhaps explaining the lack of academic inquiry). However, upon closer examination, the Beach Party Films are laden with cultural artifacts, insights into American culture of the late 1950s and early 1960s and provide a view into the tenuous relationship between 1960s American dominant culture and developing countercultures. Further, the Beach Party Films reveal a 1960s cultural lull; a culture that was caught between the dominant culture of 1950s America and the explosive cultural changes of the late 1960s that had yet to occur. By closely looking at the AIP Beach Party Films, and doing so through the lens of various cultural critics, there can be described potential cultural perspectives from early 1960s America.
Politics and the Piano during the Great Proletarian Cultural Revolution in China: An Analysis of Three Piano Works, "Music at Sunset" (1975), "Hundreds of Birds Paying Homage to the Phoenix" (1973), and "Liuyang River" (1972)
Authors:   , Liu Yuanshi
Published: December 2023

As a political disturbance and social movement, the Cultural Revolution hugely impacted the development of Chinese piano art. The piano went through many stages throughout this ten-year period. This dissertation examines the suppression and later expansion of piano music in China during the Cultural Revolution, along with the historical motivations and forces that shaped each stage of its development. The study is supported by historical documents and relevant literature. This dissertation includes an analysis of the roles that piano music played during this era and the piano's relationship with the Cultural Revolution's modernizing goals. The analysis focuses on the musical characteristics of three piano pieces from this period and explores the instrument's historical importance, to better understand how Chinese piano music maintained a careful balance between its value as a tool for socio-political propaganda and its transformation under the burden of political pressure and creative limitations. Additionally, this dissertation examines playing techniques in these works that define a distinctly Chinese piano style that is enormously popular today. To complement the dissertation, these piano pieces were performed during the dissertation recital.

3D Printed Self-Activated Carbon Electrodes for Supercapacitor Applications
Authors:   , Disi Onome Aghogho
Published: December 2023

This study investigated a new approach to achieving high energy density supercapacitors (SCs) by using high surface area self-activated carbon from waste coffee grounds (WCGs) and modifying 3D printed electrodes' porous structure by varying infill density. The derived activated carbons' surface area, pore size, and pore volume were controlled by thermally treating the WCGs at different temperatures (1000˚C, 1100˚C, and 1200˚C) and post-treating with HCL to remove water-soluble ashes and contaminants that block activated carbon pores. Surface area characterization revealed that the carbon activated at 1000˚C had the highest surface of 1173.48 m2 g-1, and with the addition of HCL, the surface area increased to 1209.35 m2 g-1. This activated carbon was used for fabricating the electrodes based on the surface area and having both micropores and macropores, which are beneficial for charge storage. Direct ink writing (DIW) method was utilized for 3D printing SC electrodes and changing the electrode structure by increasing the infill densities at 30%, 50%, and 100%. Upon increasing the infill densities, the electrodes' mass increased linearly, porosity decreased, and the total surface area increased for the 30% and 50% infill electrodes but decreased for the 100% infill electrode. Cyclic voltammetry (CV) test on the assembled SC showed the highest specific capacitance and energy density of 5.81 F g-1 and 806.93 mWh kg-1 at 10 mV s-1, respectively, for the electrode printed at 50% infill density.

The Impostor Phenomenon as a Threat to Professional Resilience and Profession-Wide Diversity in the Psychology Trainee to Workforce Pipeline
Authors:   , Williams Amber Lavonne
Published: December 2023

Racial and ethnic diversity representation in the field of health service psychology is neither equitable nor reflective of the increasingly diverse population nationwide. This discrepancy is endemic to widespread problems associated with mental health care: Minorities are severely underrepresented in the workforce, in psychology training programs, and in treatment populations. The longstanding lack of diversity among trainees in doctoral programs and among professionals in the workforce is associated with poorer mental health outcomes among minority patients; however, the specific contributors that facilitate and maintain racial/ethnic diversity constriction appear to be understudied. Based on the extant literature, a reasonable hypothesis might be that admission of qualified underrepresented minorities to doctoral training is constricted by ineffective and/or outdated recruitment and admissions practices. The proposed study sought to investigate whether impostor feelings or self-reported resilience might be predictive of intent to apply to graduate programs among underrepresented minority students earning their bachelor's degree in psychology. Results indicated that resilience was the most impactful variable in undergraduate students' intent to apply to graduate programs. Hypothesized ethnic differences in impostor feelings and self-perceived resilience were not observed in the study sample. The larger implications of these findings underscore the need for more culturally informed measures that accurately represent the experiences of underrepresented minorities in psychology's training-to-workforce pipeline. A representative workforce via is integral to optimizing treatment outcomes for underserved communities long-term and, as such, necessitates more research into problematic points on representation constriction in the training-to-workforce pipeline.
Incorporating Ethics in Delegation To and From Artificial Intelligence-Enabled Information Systems
Authors:   , Saeed Kashif
Published: December 2023

AI-enabled information systems (AI-enabled IS) offer enhanced utility and efficiency due to their knowledge-based endowments, enabling human agents to assign and receive tasks from AI-enabled IS. As a result, this leads to improved decision-making, ability to manage laborious jobs, and a decrease in human errors. Despite the performance-based endowments and efficiencies, there are significant ethical concerns regarding the use of and delegation to AI-enabled IS, which have been extensively addressed in the literature on the dark side of artificial intelligence (AI). Notable concerns include bias and discrimination, fairness, transparency, privacy, accountability, and autonomy. However, the Information Systems (IS) literature does not have a delegation framework that incorporates ethics in the delegation mechanism. This work seeks to integrate a mixed deontological-teleological ethical system into the delegation mechanism to (and from) AI-enabled IS. To that end, I present a testable model to ethically appraise various AI-enabled IS as well as ethically evaluate delegation to (and from) AI-enabled IS in various settings and situations.
Synthesis and Studies of Platinum- and Palladium-Based Porphyrin-Fullerene Conjugates to Study the Long-Lived Charge-Separated States
Authors:   , Subedi Dili Raj
Published: December 2023

The research presented in the dissertation deals with the synthesis, characterization, photophysical, electrochemical, and pump probe studies of porphyrin-fullerene based donor-acceptor conjugates. The first chapter provides insights into the introduction of the thesis, which explains the events that occur in natural photosynthesis and the mimicking process of an artificial photosynthesis based on natural photosynthesis, works done in covalently and non-covalently linked donor acceptor systems, and the penetration of the literature related to the long-lived charge-separated states donor-acceptor conjugates. The second chapter details the physical methods employed to monitor the various photochemical processes in the donor-acceptor moiety. The third chapter focusses on designing and synthesizing a platinum porphyrin-fullerene dyad used for long-lived charged-separated state. The formation of a high-energy, long-lived radical ion pair by electron transfer from the triplet excited state is orchestrated in the dyad. The porphyrin ring is modified with three triphenylamine which act as secondary electron donors. The spin state of the electrons leading to the formation of long-lived charge-separated state is demonstrated by time-resolved optical and EPR spectroscopy. The fourth chapter studies metal ligand axial coordination. Two porphyrins were self-assembled via metal-ligand axial coordination of phenyl imidazole functionalized fulleropyrrolidine. A 1:2 complex formation with ImC60 was observed in the case of (TTP)Co, while for (TPA)4PCo only a 1:1 complex was possible. Spectroelectrochemistry revealed the formation of Co (III) porphyrin cation instead of Co (II) porphyrin radical cation during the oxidation of phenyl imidazole coordinated cobalt porphyrin. Using computational and electrochemical results, an energy level diagram was constructed to visualize the various photochemical events. Using femtosecond transient absorption spectroscopy, it was possible to observe the energy transfer and charge-separation process. The fifth chapter deals with the singlet oxygen generation of platinum and palladium porphyrins. In this chapter, a series of meso-substituted porphyrins are synthesized and metalated by platinum and pallidum porphyrins and characterized by several methods. The ability of both platinum and palladium porphyrins reveals higher electrochemical redox gaps as compared to their free base porphyrins. Both platinum and palladium porphyrins can generate singlet oxygen and probe by monitoring the photoluminescence of 1O2 at 1270 nm. The study highlights the importance of different meso-substituents in triplet porphyrin sensitizers that can estimate the singlet oxygen quantum yield, which is useful for photodynamic therapy, chemical synthesis, and other applications.
Can In-vivo Self-Monitoring Improve Discrete Trial Instruction Implementation?
Authors:   , Lai Rachel Nicole
Published: December 2023

Beneficial consumer outcomes are most likely when behavior-analytic interventions are implemented with high procedural fidelity (i.e., degree to which the procedure is implemented as intended). Video self-monitoring, which involves teaching staff members to monitor their own procedural fidelity when watching recordings of themselves, can be used to improve and maintain high procedural fidelity, but video self-monitoring requires additional staff time and resources. In-vivo self-monitoring, which involves monitoring procedural fidelity during or immediately following implementing a behavior-analytic intervention, could be a cost-effective option. However, in-vivo self-monitoring needs additional research to understand its effects on procedural fidelity. This current study analyzed the effects of in-vivo self-monitoring on the procedural fidelity of three behavior technicians implementing discrete trial instruction with children with autism. We used a nonconcurrent multiple baseline across participants design to teach participants how to score their procedural fidelity during their discrete trial instruction session. Data suggested that in-vivo self-monitoring was effective for two out of three participants, and those two participants were more likely to be accurate in their self-scored procedural fidelity. Procedural fidelity for the third participant did not increase with in-vivo or video self-monitoring, and the third participant was less likely to be accurate in their self-scored procedural fidelity. During baseline and intervention, two out of three participants were more likely to error on the consequence portion of discrete trial instruction. Results of this evaluation were used to inform the supervisors about the efficacy of self-monitoring for each staff member, and implications of using self-monitoring in practice is discussed.
Investigation of Interfacial Property with Imperfection: A Machine Learning Approach
Authors:   , Ferdousi Sanjida
Published: December 2023

Interfacial mechanical properties of adhesive joints are very crucial in board applications, including composites, multilayer structures, and biomedical devices. Establishing traction-separation (T-S) relations for interfacial adhesion can evaluate mechanical and structural reliability, robustness, and failure criteria. Due to the short range of interfacial adhesion such as micro to nanoscale, accurate measurements of T-S relations remain challenging. The advent of machine learning (ML) became a promising tool to predict materials behaviors and establish data-driven mechanical models. In this study, we integrated a state-of-the-art ML method, finite element analysis (FEA), and standard experiments to develop data-driven models for characterizing the interfacial mechanical properties precisely. Macroscale force-displacement curves are derived from FEA with incorporation of double cantilever beam tests to generate the dataset for ML model. The eXtreme Gradient Boosting (XGBoost) multi-output regressions and classifier models are used to determine T-S relations with R2 score of 98.8% and locate imperfections at the interface with accuracy of around 80.8%. The outcome of the XGBoost models demonstrated accurate predictions and fast calculation speed, outperforming several other ML methods. Using 3D printed double cantilever beam specimens, the performance of the ML models is validated experimentally for different materials. Furthermore, a XGBoost model-based package is designed to obtain different adhesive materials T-S relations without creating a database or training a model.
The Experiences of Young Adult-Aged Women from South Asian Countries Attempting to Participate in Sport and Physical Activity in the United States
Authors:   , Rahman Sohaila
Published: December 2023

This study aimed to broaden the understanding of young South Asian women's experiences/relationships and participation in leisure physical activities at universities in the United States. Using a phenomenological design, semi-structured interviews of 20-30 minutes duration were conducted with 5 South Asian women about their relationships and experiences when participating or attempting to participate in physical activity while attending university in the US. The following criteria were set for participants to be included in this study: they should be between the ages of 18 and 24, non-US citizens from a South Asian country, attend a university in the US, and engage in other physical activities. The interviews were audio recorded via Zoom and then the audio data were transcribed verbatim and then coded to identify the major barriers commonly experienced by participants. Results indicated that many girls and women perceived the US as a "safer" place with excellent infrastructure, ample opportunities to engage in physical activities, and convenient access to gyms, which encourage them (women) to remain active. Most participants were hesitant to participate in physical activities because of the culturally non-responsiveness of the system. This research study was done in a shorter time span with a small sample size. Further research should explore more deeply the experiences of South Asian women regarding their physical activities in the US with larger groups of samples that may be a better representative of the South Asian population.
Detection and Classification of Cancer and Other Noncommunicable Diseases Using Neural Network Models
Authors:   , Gore Steven Lee
Published: December 2023

Here, we show that training with multiple noncommunicable diseases (NCDs) is both feasible and beneficial to modeling this class of diseases. We first use data from the Cancer Genome Atlas (TCGA) to train a pan cancer model, and then characterize the information the model has learned about the cancers. In doing this we show that the model has learned concepts that are relevant to the task of cancer classification. We also test the model on datasets derived independently of the TCGA cohort and show that the model is robust to data outside of its training distribution such as precancerous legions and metastatic samples. We then utilize the cancer model as the basis of a transfer learning study where we retrain it on other, non-cancer NCDs. In doing so we show that NCDs with very differing underlying biology contain extractible information relevant to each other allowing for a broader model of NCDs to be developed with existing datasets. We then test the importance of the samples source tissue in the model and find that the NCD class and tissue source may not be independent in our model. To address this, we use the tissue encodings to create augmented samples. We test how successfully we can use these augmented samples to remove or diminish tissue source importance to NCD class through retraining the model. In doing this we make key observations about the nature of concept importance and its usefulness in future neural network explainability efforts.
Ambient Darkness and Consumer Behavior
Authors:   , Vo Khue Ho Thuc
Published: December 2023

Ambient lighting has emerged as a key atmospheric factor influencing how consumers process environmental cues and their behaviors. However, surprisingly little research has examined how people think and feel in the dark (lower than 15 lux). This is particularly relevant given that consumers routinely work, pay bills, relax, consume and make purchases in settings with little or no light. My dissertation addresses this gap by examining how consumers regulate their goals and process information when the light is off, and how that impacts their decision making in three substantive domains: risk-taking behavior, decision quality, and persuasion. In Essay 1, I propose darkness enables risk-taking behavior, and this effect happens through the calmness and relaxation induced in the dark. One caveat is that the decisions have to be made in a familiar setting. The effect was reflected in participants' decisions to invest in riskier yet lucrative stocks, to gamble with the riskier choice, to eat at a foreign restaurant, and to choose a supplement that has potential side effects in a field experiment and three lab experiments (pre-registered). In Essay 2, I propose that when the light is off, consumers are indeed induced to adopt an effortful processing mode. Across four experiments (one field experiment, two lab experiments, and one online experiment), darkness promotes higher quality decisions across consumption contexts (financial, food, and product choices) compared to higher luminous levels. Together, this dissertation explores the intriguing phenomenon of ambient darkness and extends current understandings on ambient lighting and consumer behavior. The essays also offer robust findings through field and lab experiments with tendency and incentive-compatible outcomes.
The Governor and the Gangster: Dewey, Luciano, Commutation, and Controversy
Authors:   , Rzeppa Joseph
Published: December 2023

Thomas E. Dewey and Charles "Lucky" Luciano became household names during a 1936 vice trial in which Dewey successfully prosecuted Luciano, a prominent Mafioso, who received a thirty-to-fifty-year prison sentence. Later, Dewey became the Governor of New York and a perennial Republican presidential candidate while Luciano, still in prison, took part in a joint Navy-Mafia intelligence operation in World War II. In 1946, Governor Dewey commuted Luciano's sentence on the condition that he be deported to his native Italy. The commutation led to years of controversy fomented by the Federal Bureau of Narcotics (FBN), which downplayed Luciano's wartime services, spread rumors that he had bribed his way out of prison, and claimed that he was smuggling drugs into America from Italy. The FBN's narrative was echoed by muckraking journalists and Dewey's political opponents, finally prompting Dewey in 1954 to order an investigation that thoroughly debunked FBN assertions. However, the records of that investigation were quarantined until the mid-1970s. Since then, most scholars have used those records to explore the Navy-Mafia wartime alliance, but this dissertation exhaustively mines them and other documents in Dewey's papers, along with federal records, to disprove the FBN's narrative that there was something untoward about Dewey's commutation of Luciano's sentence and that Luciano spearheaded a drug ring during his Italian exile. Originally antagonists, the Governor and the Gangster later became unlikely allies of sorts, if only because they shared the same scurrilous detractors whose reckless accusations are belied by this study.
Differentiating Cardiac Organoids with Chamber Formations
Authors:   , Seddoh Percyval Prince-Danny
Published: December 2023

Considering that both cardiovascular disease (CVD) and congenital heart diseases (CHD) are still the leading cause of morbidity and mortality worldwide, there is a need for a robust and reliable cardiac model. Cardiac organoids are complex, three-dimensional cellular constructs that recapitulate the processes of the human embryonic heart. However, certain vital morphological features within the fetus are not yet replicable with cardiac organoids. Here we report our investigation to generate cardiac organoids with chamber formations. Our method involves modulating the Wnt pathway at two different instances while also implementing two cell seeding densities, all to determine the most optimized that to produce chamber formations within cardiac organoids.
Ready for Primetime: The American First Army at St. Mihiel, 1918
Authors:   , Jameson Sarah
Published: December 2023

The American's battle of St. Mihiel in September 1918 has long been a marginalized battle in an almost forgotten war. In the historiography of American World War I involvement, the battle is relegated to a side-show that was little more than a distraction from the Meuse-Argonne. This stance needs to be re-evaluated as St. Mihiel proved an essential training ground for the US Army. The army rapidly expanded and participated in a major offensive, completed the complicated planning process, undertook a significant deception and intelligence-gathering campaign, and led coalition forces to reduce a salient that existed for years, in only a few short months. While not a perfect operation, the Americans overcame several obstacles to form the US First Army and achieve victory. St. Mihiel is a turning point in military training and doctrine as students studied the tactics after the war into the modern day. The memory of the battle was affixed in the minds of those who fought it and those on the home front who eagerly read the news stories coming from the Western Front. Modern audiences should also recognize the significance of the Battle of St. Mihiel.
β, β'-π-Extended Porphyrins: Exploration of Functionalization and Aromatic Character

Published: December 2023

Seventeen new dithiophenyl- and napthodithiophenyl- fused porphyrins were synthesized; from these an additional 7 porphyrin oligomers were also synthesized. Additionally freebase 2,7-dimethoxytriphenylene fused porphyrin was also synthesized from a freebase precursor. Aromatic indices NICS and AICD were used to evaluate these new molecules.
The Impact of Family-Based Human Capital on Corporate Innovation: Evidence from Sibling-Chairpersons in China

Published: December 2023

We examine the impact of family-based human capital stemming from a chairperson’s having siblings vis-à-vis not having siblings on corporate innovation in Chinese family firms. Using hand-collected data, we document that when a firm has a sibling-chairperson, it holds more patents, receives more total citations to its patents, and has greater innovation efficiency and innovation quality than an otherwise equivalent firm with a chairperson having no siblings. The results are economically significant and robust to a battery of robustness checks. Specifically, the findings remain intact after using China’s one-child policy as an exogenous shock to apply a regression discontinuity research design to mitigate endogeneity. Additional analyses suggest that the mechanisms behind the impact of siblings on innovation are consistent with family-based human capital embedded in the sibling relationships such as competition, knowledge spillover, and family firm succession effect among siblings. Furthermore, we show that sibling comanagement and sibling gender diversity matter in corporate innovation. In addition, sibling effect enhances corporate investment efficiency, stock returns, and merger and acquisition performance. Overall, family-based human capital from siblings positively contributes to corporate innovation.
