ABSTRACT: The main goal of this dissertation is to examine the prosodic differences between English and Spanish that lead to different interpretations of ambiguous relative clauses. Prosody, or the rhythm, stress, and intonation of a spoken sentence, is known to have an influence on how individuals interpret ambiguous constructions (e.g., Lehiste 1973; Nespor & Vogel 1983; Price et al. 1991; Kjelgaard & Speer 1999; Schafer et al. 2000; Jun 2003; Kang & Speer 2005; Millotte et al. 2007, 2008; etc.). Additionally, individual speakers have been shown to vary their prosody depending on the syntactic structure of a given utterance (e.g., Snedecker & Trueswell 2003; Schafer et al. 2005; Kraljic & Brennan 2005; etc.). Studies like these indicate that language users (both speakers and listeners) possess implicit awareness about the relationship between syntax and prosody, and they subconsciously know that they can use this information during both production and comprehension (Snedecker & Casserly 2010). Relative clauses (henceforth, RCs) preceded by a complex determiner phrase (DP) of the type the ___ of the ___ are syntactically ambiguous because the RC could modify different head nouns. In (1a) below, the RC is bolded and could modify either the head noun son, called high attachment (HA) or the head noun senator, called low attachment (LA). The equivalent sentence in Spanish is shown in (1b). (1) a. The reporter interviewed [the son]DP1 of [the senator]DP2 who was controversial.(1) b. La periodista entrevistó [al hijo]DP1 [del político]DP2 que era polémico. The reporter interviewed to-the son of-the senator who was controversial 'The reporter interviewed the son of the senator who was controversial.' In order to investigate the prosody used by speakers of English and Spanish in disambiguation, an elicited production was designed targeting the production of sentences containing ambiguous RCs in either English or Spanish. 8 NSs of English and 6 NSs of Spanish participated in the study, in which they produced a total of 20 target items containing ambiguous RCs (10 HA and 10 LA). Results show that English speakers disambiguate HA from LA utterances using prosodic phrasing, while Spanish speakers do so using pitch accent configurations. Individuals' speech patterns and implications of the findings for the syntax-phonology interface are discussed.

ABSTRACT: This dissertation reflects on questions of identities emanating from literature and artistic works by writers and sound artists with geographical, genetic, and genealogical ties to the Congo River. It takes a chronological approach to redefine concepts of identity first discussed by Congolese thinkers immediately after the Independence Era, in the 1960s. The Independence Era refers to the period during which a great majority of Francophone countries of Africa regained their Independence from the French and Belgian governments and started to establish their own new political systems. This includes the two countries discussed in this dissertation, countries which borrow the name of the Congo River in their official denominations: The Republic of Congo and The Democratic Republic of the Congo. The aim of this dissertation is to look at the several hints left by Congolese thinkers to best describe a hybrid identity still specifically Congolese – referring to a root identity of Kongo, spelled with an initial K, without neglecting both the colonial and the postcolonial in the building of this adjusted definition of identity. As such, I dissect Sylvain Bemba's Congolie through the lens of two elements, sound and liquid. To update this concept of Congolie that I will first explain, I propose to represent all elements of Kongo, Congolie, and Congolese "diaspora" under the following phonological representation: /kongo/. Using a simplified International Phonetic Alphabet transcription between brackets refers to oralité and prevents the written choice of Congo vs. Kongo that would refer to a narrowed choice of a segment of history rather than the encompassing vision of this history. The first chapter analyzes important poetic works of Tchicaya U'Tamsi, in excerpts showing the poet's detachment from an "All-Congolese" narrative. The second chapter follows TUT's writing by scrutinizing the poetry of Sony Labou Tansi, less discussed than his novels or plays, a gap that this dissertation intends to somewhat fill. The third chapter looks at a novel by Emmanuel Dongala, Photo de Groupe au Bord du Fleuve. The narrative proposed by Dongala, a contemporary author, shows an example of the apparition of sound and liquid together in abundance within one single work and to permit the establishment and strengthening of the identity of the novel's character through cultural referencing rather than explicit naming of places (city names, countries, etc.). The fourth and final chapter follows the analyses by looking at three representative sound artists who in their own ways commented on /kongo/ through their music: Papa Wemba, Youssoupha, and Baloji. The contemporaneity of these works also allows this dissertation to open on the consideration of African and Africana Studies through the important changes that happened in the twenty-first century in that regard.

ABSTRACT: The properties of quantum spins diluted in non-magnetic crystals make them a promising candidatefor a quantum memory given their long coherence and relaxation times and their limited Hilbert space span by the electron and nuclear states of the spin Hamiltonian. In order to efficiently store and retrieve the quantum information from, let's say a superconducting qubit quantum processor, the coupling between systems is mediated by on-chip superconducting resonators that acts as a quantum bus. For this, a strong coupling between the spin quantum memory and electromagnetic mode of the superconducting resonator is needed. The results presented in this dissertation demonstrates the implementation of coupled photonic states of an on-chip superconducting resonator with a Gd3+ rare-earth ion hosted in a scheelite (CaWO4) crystal. Experiments probing the weakly coupled limit of the resonator mode with the electronuclear states of the 155,157Gd3+ isotopes diluted in CaWO4 crystal are shown. Highly sensitive field dependent cavity spectroscopy measurements showed the perturbation of the resonator properties, such as the cavity linewidth and resonance frequency. Information about the spin ensemble phase memory loss rate and coupling strength were obtained for the six observed resonances resulting from the hyperfine slitting of the Gd odd isotopes. Given the resonator microwave field distribution and carefully selecting the orientation of the static field relative crystallographic c-axis, we were able to detect highly forbidden electron spin resnonance (ESR) transitions. Additionaly, the strong coupling signal of the Gd3+ spin transition between the first and second excited state with the on-chip resonator mode is demonstrated. By analyzing the spectroscopic signal using the Dicke model that describes the interaction of photonic states with a large S spin the observed transitions were reproduced by numerical diagonalization of the spin-cavity Hamiltonian. Lastly the dynamics of the spin-cavity states were explored via pulsed ESR measurements by recording the cavity ring-down signal at different pulse lengths and drive powers. The presented results are only a first step into the exploration of the Gd3+ spin dynamics at millikelvin temperatures.

ABSTRACT: Perfluorinated carbons are hazardous molecules that have contaminated ground water systems and become a prevalent environmental issue. One group of perfluorinated carbons is a class of molecules referred to as per- and polyfluoroalkyl substances (PFAS), which have been used for decades in applications such as firefighting foams, waterproof coatings, nonstick cookware, carpets, and many others. The wide use of PFAS has led to their large accumulation in the environment. Due to this accumulation and the release into the aquifer, PFAS has become a concern in most water purification systems. Recently developed methods to degrade PFAS include advanced oxidation and reduction techniques such as photocatalysis, sonolysis, electrochemical reduction, and nonthermal plasma. Our work focuses on the degradation of PFAS with nonthermal plasma. Two example PFAS compounds, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are not only major pollutants but they are often used as model PFAS compounds, and they are the focus for this work. In this study, we use a nonthermal plasma reactor with flowing liquid and gas phases and a nanosecond pulsed power supply to degrade PFAS compounds in water. The plasma is generated with a pulsed power supply capable of variation of the input voltage, frequency, and pulse width. Through changing the input electrical pulse forming properties, we can change the plasma characteristics such as electron density, electron energy, and plasma gas temperature. The non-thermal plasma generates many different reactive chemical species such as ·OH, ·H, e-, and eaq- that may degrade PFOA and PFOS. This work shows that PFOA and PFOS are degraded into several daughter products of smaller carbon chains, and mineralization products including carbon dioxide and fluoride (F-). This work shows that PFOA and PFOS degradation are affected by concentration and pulse frequency. PFOA and PFOA are surfactants and have large surface activities. Higher surface activity leads to higher degradation and mineralization because of increased adsorption at the interface where the plasma occurs. The input frequency of the power supply changes the plasma properties and therefore PFOA and PFOS were shown to have maximum degradation percentages of 89.6% and 96%, respectively, at 2 kHz frequency. Because the degradation is dependent on initial concentration and the input frequency, these setting can be used to optimize the reactor. For comparison with other methods, the values of energy yield and EE/O are used to describe the system efficiency. Energy yield is the molar amount of the compound degraded or produced (depending on the target compound) per joule of energy. EE/O is the amount of energy used per volume per log order reduction of contaminant. The best-case energy yield and EE/O values are 6.61x10-10 mol/J and 2.5 kWh/m3(order) for PFOA and 6.691x10-10 mol/J and1.7 kWh/m3(order) for PFOS, which are better or comparable to the best reported methods for PFAS degradation. Ground water and leachate samples from field sites were treated to demonstrate the applicability of the reactor. The ground water towards the higher chain compounds, and will degrade them in order of decreasing chain length. PFOA mass transfer and reaction rates were modeled in the reactor to analyze the factors affecting the frequency and concentration effects. The model shows that the upper limit of PFOA degradation is likely mass transfer limited, but it fails to show the drop-in degradation with increasing frequency or the shift in optimal degradation with decreasing concentration.These results are encouraging for the practical application of this plasma reactor in real world remediation processes. This study furthers the understanding of non-thermal degradation of PFAS, and leads to its future use in water purification systems.

ABSTRACT: This two-article dissertation focuses on echo chambers, misinformation, and leadership in online social movements. Over the last decade, these topics have garnered much research and media attention. Concern for how misinformation and social bots may influence political action, such as voting behavior, and for how insulated spaces can amplify these effects have resulted in a wealth of research examining the issue, yet little research has explored its connection to collective action. Echo chambers are effectively black boxes, and we know little about how they impact collective action and the roles that actors within them play. In this study, I examine the characteristics of social media accounts spreading misinformation and engaging in social movement leadership tasks, whether these actions are happening within echo chambers imbedded in online social movement networks, the quality of information within those spaces, and the implications for collective action by analyzing digital leadership. I use Twitter data collected from the months leading up to, and including, the 2016 U.S. presidential election, and analyze the network structure of two movement networks, #nevertrump and #neverhillary (Chapter 2), and content analyze tweets for the presence of misinformation and leading tasks (Chapter 3). I assess whether there are echo chambers present in the movement networks and the characteristics of the network accounts. I argue that accounts centrally located in the networks will produce more misinformation, perform more leading tasks, and are more likely to be a social bot than average accounts within the movement networks. I find evidence of echo chambers and the presence of social bots across both movement networks. Results show that centrally located accounts and human users across both movement networks are associated with the spread of misinformation and the performance of leadership tasks. There is also a sizable portion of social bots among the network population, and they are more centrally concentrated within the networks. These findings extend the literature on echo chambers, misinformation, and social movement leadership by examining the characteristics of network accounts producing false claims and social movement leadership tasks.

ABSTRACT: The purpose of this study was to investigate how board-certified music therapists (MT-BCs) address communication goals with multilingual clients with communication disabilities and overall confidence throughout the process of working with this population. Specifically, an emphasis was placed on perception of overall clinical confidence by region, experience, education, and language background, perceptions of confidence throughout the therapeutic process, how music therapists address sessions with multilingual clients with communication disabilities, commonly addressed and most difficult to address communication goals for multilingual clients with communication disabilities, languages used in the therapeutic setting, and useful resources to address multilingual clients with communication disabilities. Participants (N = 122) for this study were MT-BCs in the United States recruited through an email list purchased from the Certification Board for Music Therapists (CBMT). The results of the study revealed that a majority of participants indicated an intermediate rating of confidence throughout the process of therapy with minimal relation to demographics on type of communication goals. Instrument play was the most often used music intervention. Addressing the use of conventional gestures and listening skills was the most predominant communication goal. The Spanish language was the most predominant multicultural language used in the clinical setting. Findings may be a resource for educators, clinical supervisors, and non-multilingual music therapists. Moreover, the findings may be useful to guide music therapy educational and supervisory practices. Further results and implications are discussed within the paper.

ABSTRACT: As part of the Slave Wrecks Project, excavations at Christiansted National Historic Site on St. Croix, U.S. Virgin Islands have resulted in the collection of thousands of artifacts associated with the Danish West India and Guinea Warehouse Complex, from its original construction in 1749, to the removal of the northeastern section of the complex, circa 1854. Within this assemblage hundreds of ceramic sherds of Afro-Caribbean colonoware, or Afro-Cruzan ware, have been identified. Former analysis of the colonoware established a typology as well as suggested local manufacture. In this thesis I assess the methods used to reevaluate the typology and function of Afro-Cruzan wares as a product and symbol of the Trans-Atlantic Slave Trade. This study includes provenance analysis to determine whether these wares were produced locally on St. Croix or elsewhere to identify potential spheres of interaction, and if the same sources of material were used in prehistoric times. It is proposed that Afro-Cruzan ware represents cultural and economic perseverance, despite colonial oppressive conditions. Thus, this research highlights enslaved and free Africans' lives as they sought to maintain autonomy through daily tasks expressed through ceramic traditions.

ABSTRACT: As of 2017, there were 1.4 million Americans living in nursing homes and as the senior population continues to grow and the average life span becomes greater, it is anticipated that the need for nursing homes will increase (National Institute on Aging as cited by Neufeld, 2017). As individuals age they often experience decreased independence, cognitive declines, and physical health issues leading them to require assistance from family members or relocate into a living facility, such as a nursing home. During relocation individuals can enter a liminal period - understood as being between one phase of life and another - as they transition into a newer life role (Barrett et al., 2012). However, there is currently little existing research that addresses nursing home design and its role in supporting the wellbeing of residents as they transition to the nursing home. A review of Lawton's Person-Environment (P-E) Fit theory suggests that a fit environment is critical for older adults' transition out of the liminal period and supports their physical and psychological health. A fit environment should accommodate the user's limitations and allow them to adapt (Park et al., 2017). This research seeks to identify spaces in the living facility that support the wellbeing of long-term nursing home residents and develop a list of common design characteristics that may support resident wellbeing to facilitate a comfortable life transition into their new living environment. A phenomenological study was conducted including behavioral mapping observations, a focus group with residents, and a resident interview to generate further understandings of how the nursing home is used by residents and the residents' perspective of the living environment. Findings from the original research and knowledge gathered through precedent studies of senior living facilities have been applied to a theoretical redesign of a nursing home in Tallahassee, FL.

ABSTRACT: From an educational equity perspective, all students need to have appropriate learning opportunities that are close to their own cultural contexts (e.g., families and communities). Based on the transformative social-emotional learning (SEL) framework, the mixed-methods study explored how culturally relevant reading experiences can be longitudinally linked with underserved students' social-emotional and academic development. Specifically, this study explored changes in underserved students' prosocial self-efficacy and reading skills across multiple years of involvement with a culturally relevant reading program at Freedom Schools. The multicultural reading program at Freedom Schools is rooted in culturally relevant pedagogy and SEL to empower racially-minoritized students to make a difference. The purpose of the six-week summer camp is to help underserved students maintain their reading skills during the out-of-school summer period. To explore possible sustainable learning outcomes from experiences at Freedom Schools, this study focused on targeted participants who participated in the Freedom Schools camp for at least two years (i.e., returning students in 2016 through 2019). The purpose of the study was to investigate students' prosocial self-efficacy and reading skill outcomes over time. From the four years of annual data from Freedom Schools participants, I identified data with parental consent for a total of 50 returning students. For the quantitative analysis, I investigated returning students' individual change patterns in prosocial self-efficacy (n = 38) and reading skills (n = 22). To support the results from the individual change patterns, I also analyzed 16 interviews from eight returning students; each student participated in two interviews that were collected during different summer years of Freedom Schools.According to the descriptive results of this study, within the summer program period (i.e., during the six-week), returning participants at Freedom Schools showed descriptive positive changes in their prosocial self-efficacy in their first camp (67.7%) and their second camp (57.6%); however, between the first and second camps, their prosocial self-efficacy changes varied across individuals. The majority of returning participants showed descriptive positive reading changes. For example, returning students descriptively increased or maintained reading skill levels in their first camp (at least 85% of participants in all reading subfactors) and in their second camp (at least 80% of participants in all reading subfactors). The summer program aimed to prevent summer reading loss of underserved students, so maintained reading scores were marked as positive outcomes within the summer camp period. More than 60% of returning participants had descriptive increases in reading skills between the first and second summer camps. There were no noticeable general change patterns between the prosocial self-efficacy and reading skills. Due to the complex change patterns of students' prosocial self-efficacy across the multiple years, there were no general patterns to explain the relationship between prosocial self-efficacy and reading skills of returning participants. Through the interview analysis, I found that all interviewees had positive views on their summer learning experiences; students commented that their teacher and peers were supportive and respectful in the classroom, and the multicultural books in the camp were interesting to them. The learning and instructional contexts of Freedom Schools align with the transformative SEL approach. In this study, students' interviews aligned with the theoretical ideas of transformative SEL that using culturally relevant education may support students' positive cultural identities and successful academic achievement in racially minoritized students. The findings contribute to our understanding of students' transformative SEL experiences in Freedom Schools contexts. This approach highlights the importance of equity-based SEL implementation for underserved students. The findings of this study also shed light on the impact of Freedom Schools on students' potential learning outcomes across multiple years, from a developmental perspective.

ABSTRACT: A search is presented for a light pseudoscalar Higgs boson using full Run 2 data (2016-2018) collected by the CMS (Compact Muon Solenoid) experiment at the LHC (Large Hadron Collider), corresponding to an integrated luminosity of 137.60 fb−1 and at a √s = 13 TeV. The study looks into the decay Higgs boson (H) via the H→aa→ μμτ τ channel. The Higgs boson can be both standard-model-like (125 GeV) or heavier. The pseudoscalar mass falls within the range ma[2mτ , mH /2]. The large mass difference between the Higgs and the pseudoscalar means that the final tau lepton decay products are highly boosted in the decay direction and collimated. A modified version of tau reconstruction is used to account for the highly overlapping decay products. The modified reconstruction technique gives higher reconstruction efficiency over the standard tau reconstruction and hence better signal significance and background rejection. In the absence of a significant signal, model-independent limits are set at 95% C.L. on the branching fraction for H→aa→ μμτ τ as a function of ma. The document also discusses the operations and commissioning of the CMS Phase-1 pixel detector.

ABSTRACT: With the rapid development of Artificial Intelligence, Machine Learning technologies have entered a fast-evolving era. This dissertation covers application studies of various algorithms ranging from traditional machine learning methods to deep neural networks. In the first study, we predicted Female Breast Cancer Incidence Rates using prevailing machine learning techniques for 1,754 US counties with a female population over 10,000. Outlier counties with unexpectedly high or low FBC IRs were identified by controlling the non-modifiable factors (demographics and socioeconomics). Geographic clusters of outlier counties as well as impacts of modifiable factors (lifestyle, healthcare accessibility, and environment) were also mapped. Our study pioneers the county-level assessment, which takes both individual and population risk factors into consideration across 6 state-of-art machine learning algorithms. Moreover, the framework we developed can be applied to studies of other types of cancer. Diving deep into deep learning in particular, we investigated text mining models of biomedical Named Entity Recognition and Relation Extraction on both social media texts and scientific publications. For social media texts, we developed a PubMedBERT-based classifier trained with a combination of multiple data augmentation approaches. Our study explored the effects of various data augmentation strategies on extremely imbalanced data, which has not been experimented thoroughly before. It has achieved an F1 score of 0.762, which is substantially higher than the mean of all submissions (0.696). For scientific articles, we design and train two NLP systems that effectively extract biomedical entities and relations information. As a result, our methods achieved Top 4 in BioCreative VII track 3 and Top 1 in LitCoin NLP challenges.

ABSTRACT: Knowledge of a species' range, movement patterns, and associations with environmental factors provides essential insights into their ecology. Together, these datasets can inform effective conservation measures by identifying ecologically important habitats and can be used to forecast changes in space use in response to disturbances (e.g., climate change impacts). Methods of obtaining spatial distribution data for marine species have proliferated due to recent technological advances, with passive acoustic and satellite telemetry emerging as two common tracking approaches. These approaches are often used for similar purposes of quantifying the space use and home ranges of individuals; however, data-driven comparisons of these methods and the ecological inferences that can be made from each are lacking. To systematically compare telemetry methods and make recommendations of their appropriate applications, nine juvenile green turtles (Chelonia mydas) were simultaneously tracked with both passive acoustic and Argos satellite telemetry within a foraging area in Bimini, Bahamas. The temporal durations, spatial resolution and extent, and costs of each tracking approach were compared. Dynamic Brownian Bridge Movement Models (dBBMMs) were applied to estimate and compare 95% and 50% utilization distributions (UDs) between tracking methods. Additionally, overlap indices were calculated to assess the degree of agreement between the UDs from each approach. The mean tracking durations of acoustic and satellite telemetry were similar (87 d and 119 d, respectively), although acoustic tracking provided a higher number of relocations per individual at a finer spatial and temporal scale. UDs estimated from satellite telemetry were on average 7 to 15 times larger than those estimated from acoustic telemetry. The differences in UD size were not statistically significant, although this was potentially an effect of the small sample size and high individual variability. Overlap indices indicated a moderate agreement between 95% satellite and acoustic UDs, but a low agreement between 50% UDs. Satellite telemetry confirmed that individuals generally remained within the extent of the acoustic receiver array; however, a large proportion of satellite UDs fell outside individual receiver detection ranges, suggesting that large gaps in coverage existed within the array. These results indicate that passive acoustic and satellite telemetry do not provide similar inferences about individual space use within foraging areas and should each be used to address specific ecological questions and be uniquely interpreted. While acoustic telemetry using a localized passive array is better suited for understanding ecological associations on a fine spatiotemporal scale, such as diel movement patterns, satellite telemetry is better suited for assessing movement corridors or resource selection patterns. Additionally, large differences in costs were found based on transmitter type, sample size, and the pre-existence of a receiver array, all of which should be taken into consideration when designing a telemetry study. Recommendations are made to help researchers identify the most appropriate telemetry methods for their research objectives and to aid in appropriately interpreting space use metrics from various telemetry methods.

ABSTRACT: The first chapter in this dissertation explores the welfare benefits from relationship banking that arise from the information gleaned by banks through monitoring. If monitoring reveals not only current output, but also new information about future payoffs, lenders can shield themselves from future losses through early termination of lending agreements. In a competitive lending environment, banks shift the benefits of early termination to borrowers through the lending terms, improving not only the overall expected payoff of projects, but also the welfare of borrowers. Numerical results reveal that the benefits of long-term relationships based on the information revealed in monitoring could be substantial. The second chapter explores the inequality implications of automation. Changes in income inequality from advanced automation may stem from two sources. Wages may become more unequal as lower skill tasks that are currently performed by workers are done in the future by computerized capital. With higher relative wage income, high-skill workers will be able to afford investments in capital that are out of reach for low-skill workers, exacerbating income inequality further. Using a general equilibrium model of task-based production, we disentangle the impacts of automation on wage, wealth, and income inequality. Next, using this framework, we discuss policy interventions for addressing inequality, including transfers and taxes on factors, including the political economy implications of such policies.

ABSTRACT: Salamanders are often the most abundant vertebrates in forest communities and perform important ecological functions by acting as both predators and prey. Their decline, extirpation, and potential extinction can have dramatic effects on the environment through disruption of predator-prey interactions and alteration of nutrient cycles. Salamanders are also sensitive to habitat encroachment, disease, chemical contamination, and climate change, and their declines serve as an indication that environmental health may be compromised. Unfortunately, salamander declines and extinctions have been reported around the world. Several causes contribute to the declines including land use change, chemical contamination, over exploitation, invasive species, climate change and emerging pathogens.In the Eastern US, salamanders have experienced precipitous declines since at least the 1950s. Some have identifiable causes, but many declines are enigmatic, and studies are needed to identify potential causes and assess population status before restoration is possible. In Florida, declines have been reported in populations of Frosted Flatwoods Salamanders (A. cingulatum), Reticulated Flatwoods Salamanders (Ambystoma bishopi), Striped Newts (Notophthalmus perstriatus) and presumed Spotted Dusky Salamanders (D. cf. conanti). Two other salamanders in Florida may also be in decline: the Seal Salamander (Desmognathus monticola) and the Southern Dusky Salamander (D. auriculatus). Dusky Salamanders (Family: Plethodontidae, Genus: Desmognathus) represent an understudied clade of lungless amphibians which are difficult to distinguish due to morphological conservatism. However, modern genetic techniques are revealing a previously hidden abundance of diversity, suggesting that local extirpation of "populations" may in fact represent species level extinctions. The overarching goals of my dissertation was to evaluate the current status of D. monticola and D. auriculatus in Florida and attempt to identify possible agents of their decline. I also investigated the prevalence of amphibian chytrid pathogens in historic and contemporary salamander populations in Florida. To answer my first question, I established historic location distributions in Florida from museum preserved specimens and surveyed all possible historic sites with traditional field techniques. Desmognathus monticola was restricted to a small series of ravines forming an unnamed tributary of Canoe Creek, Escambia Co. We were unable to locate any specimens in the field, and show the population declined after their initial discovery in 1969. Desmognathus monticola has not been seen in the state of Florida since 2002 and appears to have been extirpated by poor land use practices. For D. auriculatus, I developed a custom environmental DNA (eDNA) assay and field collection technique to assist with species detection. I tested the effect of lentic versus lotic water habitat and pH on the efficacy of detecting D. auriculatus eDNA at sites of known presence. Although I found no significant effect of pH on eDNA detection success, I was unable to detect eDNA in lentic systems. However, I achieved 100% detection success at lotic system sites. I also detected D. auriculatus eDNA at one site of previously unknown presence but was unable to locate any live specimens during traditional surveys. I recommend conducting additional surveys at the site to ensure the eDNA detection was not a false positive. Finally, I conducted extensive field surveys throughout Florida to locate populations of D. auriculatus. I surveyed most historic collection sites and many new sites but found an extreme reduction in their area of occupancy, with the decline occurring in the 1970s. The Southern Dusky Salamander is now restricted to a few fragmented pockets in North Florida and appears to be extinct in the Florida Peninsula. Although the amphibian chytrid pathogen Batrachochytrium dendrobatidis (Bd) is present in current and historic salamander populations, its prevalence is low and does not appear to be the agent of decline. However, it is possible that infected wild D. auriculatus die shortly after contracting Bd and went untested, biasing our results. I was unable to determine the agent of D. auriculatus' decline, but comment on potential causes. In conclusion, my research is the first formal survey of the status of D. monticola since its initial discovery in 1969. I cannot assign a cause to its disappearance, but the most likely candidate is habitat destruction from poor forestry management. My research is also the first formal survey of D. auriculatus' status throughout the state of Florida. I demonstrate the utility of eDNA in locating the species, identify remaining populations, and address several possible causes of the species' decline.

ABSTRACT: Meson photoproduction off the nucleon has long been serving as a tool for understanding the properties of hadrons. At lower energy scales, the production mechanisms are dominated by the $s$-channel inelastic scattering process, where the proton absorbs the photon, gets excited to the resonance state, and then decays. Nucleon resonances have been extensively studied in this energy regime using techniques such as partial wave analysis. When the energy scale increases, the production mechanism gradually transitions from the formation of nucleon resonances to the pure scattering process, corresponding to the $t$- and $u$-channel exchange. However, the scarcity of cross section and polarization data over the photon energy range 3-6 GeV have thus far hindered our understanding of the mechanism transition from nucleon resonance to the $t$-channel Pomeron and Reggeon exchange. This work presents differential cross sections for the reaction $\gamma p\rightarrow p\eta$ with energy-tagged photon energies between 1.2 and 4.7 GeV using the CLAS spectrometer at Jefferson Laboratory. The $\eta$ meson is reconstructed in its dominant charged decay channel $\eta\rightarrow \pi^{+}\pi^{-}\pi^{0}$. The energy scale extends from the nucleon resonance regime to the Regge regime, allowing for studying the $t$-channel exchange mechanisms. The d$\sigma/$d$\Omega$ differential cross sections are compared with predictions of $\eta$-MAID 2018 and the latest solution of the Bonn-Gatchina coupled-channel analysis. In the energy regime $W>2.5$ GeV, the d$\sigma/$d$t$ differential cross sections are presented in comparison with the Regge model from the Joint Physics Analysis Center. The data confirm the expected dominance of $\rho$, $\omega$ vector-meson exchange. Differential cross sections and spin density matrix elements (SDMEs) are also measured for the reaction $\gamma p\rightarrow p\omega$ in the energy range $1.6<E_{\gamma}<5.4$ GeV. The $\omega$ mesons are detected in their dominant charged decay mode $\omega\rightarrow \pi^{+}\pi^{-}\pi^{0}$. In the center-of-mass energy range $W\in$ [2.45, 3.25] GeV, the d$\sigma/$d$t$ differential cross sections are presented in comparison with the prediction of the Regge model provided by J. M. Laget. Circularly-polarized SDMEs Im$(\rho_{10}^{3})$ and Im$(\rho_{1-1}^{3})$ are measured for the first time, while the unpolarized SDMEs $\rho_{00}^{0}$, $\rho_{1-1}^{0}$ and Re$(\rho_{10}^{0})$ in the higher momentum transfer regime $-t>0.6$ GeV$^{2}$ are also first measurements. The unpolarized SDMEs are compared with two models from J. M. Laget and the Joint Physics Analysis Center, respectively. The behavior of $\rho_{00}^{0}$ and Re$(\rho_{10}^{0})$ is consistent with the model predictions, whereas $\rho_{1-1}^{0}$ goes to the opposite sign direction relative to the models. Given the relative proportion between the natural- and unnatural-parity exchanges plays an important role in shaping the matrix element $\rho_{1-1}^{0}$, this discrepancy indicates the new data are in favor of smaller contribution of the unnatural-parity exchange than the model predicts.

ABSTRACT: Children with ADHD show impairments in set shifting task performance. However, directly training shifting has not improved task performance in this population. We hypothesized that this incongruence may be because the impairments exhibited by children with ADHD during shifting tasks are due to deficits in other executive functions, as shifting tasks also include working memory and/or inhibitory control demands. Therefore, this randomized controlled trial examined the extent to which neurocognitive training of working memory vs. inhibitory control produced improvements in set shifting task performance for children with ADHD. Children with ADHD ages 8-12 (M=10.41, SD=1.46; 12 girls; 74% Caucasian/Non-Hispanic) were randomized to either central executive training (CET; n=25) or inhibitory control training (ICT; n=29). The study's primary analyses included a series of 2 (group:CET/ICT) x 2 (timepoint:pre/post) ANOVAs for speed and accuracy shift costs, separately for two set shifting tasks (Global-Local and Number-Color). Results of the speed ANOVAs indicated that ICT improved set shifting speed (p=.02, BF10=4.53, d=0.57) on the Global-Local task and reaction times specifically during shift trials (d=0.38) on the Number-Color task, whereas the CET group showed non-specific improvements in speed on the Number-Color task (shift trials, d=0.70; non-shift trials, d=0.68). Results of the accuracy ANOVAs indicated that ICT was superior to CET for improving set shifting accuracy (p=.02, BF10=2.18, ω2=.04) and overall task accuracy (ω2=.01), albeit on only one task. Taken together, results of the current study suggest considerable overlap in variance between set shifting and the other two core executive functions in school-aged children and provides preliminary evidence for the effects of training the other two core executive functions on set shifting difficulties performance in children with ADHD.

ABSTRACT: We are currently in the era of big data, where data of enormous volume and variety is generated continuously, and they need to be captured, processed, and analyzed at a high velocity.Many users have increasingly adopted big data analytics to analyze and extract value (e.g., supporting business decisions and uncovering new insights) from massive amounts of data. Modern cluster computing frameworks (e.g., Spark) have facilitated this widespread adoption of analytics by providing developer-friendly APIs and excellent performance on diverse systems. While modern data analytics frameworks have achieved incredible advancements in terms of speed and performance, non-trivial challenges have emerged due to various factors, such as the increasing size of datasets, increasing complexity of the configuration-performance relationship, and a shift from on-premise infrastructure to the cloud. These challenges need to be tackled for the continued growth of the big data revolution. The growing trend of larger dataset sizes translates to a higher requirement for system resources (e.g., compute, memory, storage).This increase in demand is exacerbated by the fact that modern data analytics frameworks rely heavily on memory for providing significant performance gains over the previous generation of disk-based frameworks. Currently, the decrease in DRAM price is outpaced by the growth in dataset sizes, and Non-Volatile Memory (NVM) is a promising solution for meeting the increasing demand for memory. However, a complete replacement of DRAM by NVM is not viable due to NVM having several drawbacks, namely higher access latency, lower bandwidth, and endurance. Thus hybrid memory architectures that provide higher capacity at a lower cost by combining DRAM and NVM to overcome the disadvantages of NVM have been proposed to tackle the issue of increased memory requirement. Unfortunately, current memory management mechanisms within modern data analytics frameworks are not suitable for hybrid memory and require to be redesigned and optimized for taking advantage of such systems. Even if data analytics systems have enough resources, achieving optimal utilization to extract the best workload performance is immensely challenging. For proper utilization of cluster resources, analytics workloads need to run on optimal configurations. As modern data analytics frameworks mature, more configuration parameters are introduced for adapting to new use cases and systems. While new parameters allow the frameworks to be more flexible and versatile, this increases the dimensionality of the configuration space. Each new dimension in the configuration space exponentially increases the number of possible configurations, which makes determining the optimal configuration significantly difficult. Furthermore, the relationship between workload configuration and performance is complex. Existing tuning solutions require numerous workload execution samples to train a performance model for handling the complex configuration-performance relationship. However, running analytics workloads with large datasets is costly, rendering current solutions unsuitable in most real-life scenarios. A viable automated tuner needs to recommend optimal or near-optimal configurations within a limited number of iterations and keep costs low. Another phenomenon that adds to the challenge of optimal resource allocation and utilization is the shift towards the cloud for running analytics workloads. Cloud service providers offer hundreds of Virtual Machine (VM) types that differ in compute, memory, network, and storage capabilities. Choosing the optimal number and type of VMs from the numerous possible combinations for workload deployment is a significant challenge. While contemporary solutions have advanced the field of cloud configuration tuning, they have limitations in the form of predetermined search spaces and underutilization of domain-based heuristics. This dissertation tackles the mentioned issues through three studies that propose architectural modifications and novel automated tuning frameworks for efficient data analytics.Firstly, we investigate the integration of Non-Volatile Memory (NVM) through hybridization in the memory management mechanisms of Spark. We propose several modifications to the software stack to effectively support the hybridization of the Spark cache in an optimized manner. Our evaluation results have demonstrated that the proposed hybridization strategy keeps the increase in execution time minimal while only requiring a fraction of DRAM compared to a fully DRAM system. Secondly, we offer a high-dimensional cluster configuration tuner called ROBOTune that finds optimal or near-optimal configurations for efficient data analytics. ROBOTune employs a Random Forests model to handle the high-dimensionality of the analytics configuration space and couples it with a Bayesian Optimization engine to search for optimal configurations within a limited budget. Evaluation of an extensive set of applications shows that ROBOTune finds configurations that perform better on average while significantly improving search cost and search speed compared to contemporary solutions. Thirdly, we propose a cloud resource allocation tuner BoundConfig, which utilizes framework-level execution metrics for dynamically determining a workload-specific cloud VM search space. We also employ domain-driven heuristics for identifying well-performing initial configurations to bootstrap the tuning process. Furthermore, BoundConfig couples these techniques with a Bayesian Optimizer equipped with a noise-resilient acquisition function and metric-based output constraints that guide the search. Workload-specific search spaces reduce the tuning cost, while well-performing initial configurations speed up the process. Our extensive experiments for BoundConfig on AWS EC2 have demonstrated its significant advantage in search speed and cost compared to contemporary solutions.

ABSTRACT: The air intake captures the freestream airflow and delivers it to the engine of the parent vehicle for thrust production. The shockwave boundary layer interactions (SBLI) in the intake duct play an important role in defining the flow characteristics of supersonic air intakes. At certain operating conditions, these SBLI may result in large-amplitude oscillations in the intake flow, and be detrimental to the safety and performance of the engine. In addition, the back-pressure rise due to combustion instabilities can cause the intake to unstart. The unstart phenomenon generally turns out to be fatal for aerial vehicles due to loss of thrust and control. In spite of several previous studies focused on the intake unstart at certain operating conditions, a comprehensive understanding of flow states that occur during an unstart process is needed to develop a reliable engine control system. Both active and passive flow control techniques have been employed previously for the SBLI control to improve intake safety and performance. Particularly, cowl SBLI control has been targeted as it plays an important role in defining the performance and unstart characteristics of an intake. It has been shown in the literature that a simple backward-facing step (BFS) can be used as a passive control device for a canonical impinging SBLI. However, the use of a BFS has never been exploited for the SBLI control in supersonic air intakes. Previous studies led to the following questions. 1) Can a passive flow control device (suitably modified BFS) improve the performance of an air intake i.e. total pressure recovery and flow uniformity? 2) How does this passive flow control technique affect the mean flow behavior and dynamics of the air intake at different back-pressures? 3) Will there be any change in the intake unstart characteristics with SBLI control? To answer these questions as our research objectives and to improve our fundamental understanding of the supersonic intake flows, in particular the unstart phenomenon, a comprehensive experimental and numerical investigation is conducted and the results are presented in this work. The passive flow control device investigated in this study is a modified BFS, embedded at the ramp-isolator junction and is called a "Notch". The baseline intake geometry without a Notch is referred to as a Faceted configuration. The experiments include steady and unsteady wall pressure measurements, rake (total) pressures, back-pressure measurements, pressure sensitive-paint (PSP), planar particle image velocimetry (PIV), shadowgraphy, and oil flow visualizations. The numerical simulations include the Navier-Stokes-based mean flow Perturbation (NS-MFP) method for the linear analysis, Large Eddy Simulations (LES), and Reynolds Averaged Navier Stokes (RANS) simulations for the non-linear analysis. Numerical simulations predicted a region of flow separation and Kelvin-Helmholtz (K-H) instability around the isentropic compression surface of the external ramp. The ramp separation bubble also harbors a three-dimensional stationary instability that can induce transition under the influence of shear layer instability. The streamwise oriented G{\"o}rtler vortices break down to turbulence due to secondary instabilities. The flow transitions to turbulence over the ramp before it enters the inlet-isolator duct. At low back-pressures, the inlet-isolator flow is predominantly two-dimensional (2D) and the shock train is located in the divergent section. The experiments displayed a comparatively higher level of pressure fluctuations and a fuller boundary layer in the Notched intake isolator. The LES demonstrated the underlying mechanisms at work is the mid-frequency energization through vortex shedding in a well-developed shear layer. The Notch results in lower static pressures and higher velocity fluctuations, which will reduce the structural loads while improving flow uniformity and total pressure recovery. At high back-pressures, the shock train moves upstream and transitions to an oblique shock train. The notch effectively locks the separation at the ramp-isolator junction which is otherwise free to move in the baseline intake. Strong three-dimensional (3D) behavior exists in the inlet-isolator flow at high back-pressures due to severe adverse pressure gradients and regions of flow separation around the shock train. The highest level of unsteadiness in the intake was found to be around a normal shock train in the isolator. The oblique shock train showed mild low-frequency dynamics which can be linked to the large-scale separation at the isolator entrance. The flow choking near the intake exit triggers the unstart wave which propagates upstream. The unstart occurs through the development of a large-scale separation and boundary layer thickening at the ramp-isolator junction. The Notched intake displayed lower wave speed and a higher margin of unstart as compared to the baseline. The improvement in the understanding of the intake flowfield has laid down a path for future intake flow control efforts. The passive flow control device has displayed the potential to control SBLI and improve performance in supersonic intakes. The lessons learned in this study can be extended to other high-speed flows and applications during design and analysis.

ABSTRACT: Music therapy interventions have proven to reduce anxiety, diminish stress, palliate pain, increase medical care satisfaction, and show benefits in acute symptom management. The emergency department is a concentrated hospital area where patients experience immediate physical and psychological needs. With music therapy's known benefits, it should be evident that music therapists belong in emergency situations, however, research highlighting music therapy interventions in the emergency department is lacking.

ABSTRACT: Nineteenth-century French censorship has had a profound impact on both the production and dissemination of literary works. The Loi de 1819, which established one of the first state-sponsored systematic policies of censorship in France, required writers and publishers to produce works that would avoid tout outrage à la morale publique et religieuse, ou aux bonnes moeurs and anyone who failed to comply risked being punished by imprisonment of up to one year and fined up to five hundred francs. In a strategic attempt to avoid the social and economic sanctions of censorship legislation such as the Loi de 1819, French writers such as Théophile Gautier, Charles Baudelaire, and Rachilde successfully deployed defensive writing strategies including acts of incompletion, direct omission, association, disassociation, rhetorical narratives, and linguistic shifts. By focusing on three case studies of writers from different periods in nineteenth-century France, this project foregrounds the banning of books on moral rather than political or religious grounds. Building on the scholarship of Elisabeth Ladenson, Yvan Leclerc, and William Olmsted, it aims to bring to light the censorship experience of French writers under different regimes (the July Monarchy, the Second Empire, and the Third Republic) as they battled against or colluded with external (e.g. state-sponsored) as well as internal (e.g. productive) censorship. In addition, moving beyond the well-known comparison of the 1857 trials of Gustave Flaubert and Baudelaire allows for the analysis of successive but distinct periods of censorship in nineteenth-century France demonstrating that writers in other periods, notably the July Monarchy and the Third Republic, faced similar social and economic constraints. This longitudinal approach allows for the inclusion and analysis of Gautier and Rachilde whose works have not been studied through this lens. Furthermore, rather than delve into book banning process after the publication of a work, this project is unique in that it scrutinizes censorship before and after the act of expression. Analyzing censorship before the act of expression highlights the internal or productive qualities of censorship, which are, again, rarely studied in critical censorship discourses. As book bans and free speech remain contemporary issues, the findings and conclusions of this project focused on the period from 1830 to 1890 identify a framework for future censorship inquiries in literary studies—one that highlights attention to the internal and external pressures restricting expression and explores the ways writers actively evade this censorship.

ABSTRACT: This dissertation is a collection of our research on star forming cores. We used tracer particles to record time dependent information on the gases that make up these cores. From these information we deduced core characteristics. We found that as time progresses, cores approach a state of coherency as defined by (Goodman et al. 1998b) and Larson (1995). At a core's coherency phase, it also forms an ρ ∝ r−2 density radial profile. This is an indication of symmetric spherical collapse as described by Larson (1969), Penston (1969a) and Shu (1977). Spherically symmetric happens because the effects of magnetic fields are dampened by that of the gas, meaning that magnetic fields have little effect on a coherent core's dynamics. We also found evidence that cores accretes mass after fragmentation occurs, and a coherent core has formed. This evidence was discovered by looking at density vs time plots of our cores, as well as from studying the density probability distribution function (PDF) of our molecular clouds. Using our density (PDF) we also analytically derived an expression for the star formation rate. Finally studying the gravitational binding energy of our cores, we found that coherent cores has a radius around 1 × 10−2 pc, is gravitationally bounded, and has a potential that is spherical. This add credence to the idea that our cores are going through spherically symmetric collapse at the point of coherency. Finally, We found that the gravitational binding energy outside of the coherent regions of our cores is greater than that of a spherical core. This trend is universal to most cores, including the most isolated ones. This indicates that a global potential, or semi-global potential, might be the agent of accretion.

ABSTRACT: This dissertation studies Xenophon's engagement with fifth-century intellectual culture. In particular, it examines the ways in which Xenophon situates Socrates within and in relation to the sophistic movement. I demonstrate that the sophistic movement is not only essential for understanding Xenophon's intellectual project and his portrayal of Socrates, but also that Xenophon himself is an overlooked but valuable source for the intellectual history of the fifth century. The introduction explains the motivation for the project and situates it within the bourgeoning fields of study on Xenophon and on the sophistic movement, respectively. The second chapter studies Xenophon's diverse rhetorical strategies of demarcating intellectuals. The terms sophistēs and philosophos, my analysis shows, display significant semantic overlap in Xenophon's corpus. Consequently, attending to Xenophon's lexical choices, I argue, allows us to rethink several prevalent assumptions about Xenophon's views of the sophists. It also indicates that, if we are to understand his views of fifth-century intellectual culture, we must look beyond his lexical choices. The remainder of the dissertation examines how Xenophon presents Socrates vis-à-vis four topics or debates that were central to the sophistic movement and intellectual culture in his time: natural philosophy, the use of poetry in education, the teachability of virtue and the moral responsibility that attends education, and the question of self-interest. The third chapter turns to Xenophon's Socrates as both a critic and reformer of natural philosophy and argues that Xenophon presents Socrates' innovative natural theological views as a response to Anaxagorean physics. Xenophon's defense of Socrates, my examination reveals, is programmatic for Xenophon's own views on the intellectual and educational marketplace in the fifth century BCE. The following three chapters all study Xenophon's presentation of Socrates qua teacher, and ask how Xenophon portrays Socrates as similar to and yet different from other fifth-century educators like Protagoras, Prodicus, Gorgias, and Antiphon. The fourth chapter focuses on the role of poetry in Socrates' (and other sophists') pedagogy, and demonstrates that Socrates was deeply embedded in (and critical of) the educational practices of his day. In turn, the fifth chapter takes up a debate on the responsibility teachers bear for the behavior of their students. I argue that, in the Anabasis, Xenophon's presentation of Gorgias as the teacher of Proxenus and Meno engages intertextually with Plato's Meno and Gorgias concerning debates about pedagogical responsibility. I compare Xenophon's treatment of Gorgias with his handling of Socrates' responsibility for Critias and Alcibiades, and demonstrate that Xenophon (and his Socrates) are critical of teachers like Gorgias who neglect to care for the moral character of their pupils. At the end, the sixth chapter considers how Xenophon situates Socrates within a live fifth-century debate about self-interest. While drawing on the work of other sophists, like Prodicus, to make his case, Xenophon opposes Socrates to advocates of a civically-harmful form of self-interest, like Antiphon. The centerpiece of this debate, a conversation between Socrates and his companion Aristippus, highlights the moral urgency and pedagogical importance of the debate. The findings of this and the preceding chapters demonstrate that Xenophon's Socrates and thereby Xenophon himself were fully engaged in the intellectual culture of the sophistic movement. The seventh chapter offers a brief conclusion and directions for developing this project further.

ABSTRACT: Tukey's depth offers a powerful tool for nonparametric inference and estimation but also encounters serious computational and methodological difficulties in modern statistical data analysis. This article studies how to generalize Tukey's depth to problems defined in a restricted space that may be curved or have boundaries, and to problems with a non-differentiable objective. First, using a manifold approach, we propose a broad class of Riemannian depth for smooth problems defined on a Riemannian manifold and showcase its applications in spherical data analysis, and principal component analysis, and multivariate orthogonal regression. Moreover, for nonsmooth problems, we introduce additional slack variables and inequality constraints to define a novel slacked data depth, which can perform center-outward rankings of estimators arising from sparse learning and reduced rank regression. Real data examples illustrate the usefulness of some proposed data depths.

ABSTRACT: Why do public organizations and communities collaborate with each other? And what are the social and environmental outcomes of collaborative governance? This dissertation develops three essays to answer both questions. The first essay applies a conjoint experiment to investigate the determinants of interlocal collaboration decisions of U.S. municipal officials. This research extends multiple organizational network theories to organizational decision makers. The findings confirm these theories and offer new insights. The second essay explores the effects of trust in government on citizens' perceived collaborative governance and their willingness to coproduce. Using randomly assigned government integrity information as the instrumental variable of trust, the results reveal complex relations of citizen-state interactions. The third essay examines the outcomes of intergovernmental collaboration in water pollution control in China. Using the water quality panel data with the synthetic control method, this study finds that the mandated collaborative governance model effectively reduced the level of water pollution in an inter-jurisdictional river. Overall, this dissertation explores the theory of collaboration from its initial motivation to its final outcomes. The utilization of various innovative causal identification methods moves the research of collaborative governance a little step forward.

ABSTRACT: Games have shown to be great tools for learning a variety of topics, but few games have been developed mathematics topics at the undergraduate level. One possible avenue is to pursue digital game-based learning. The game Vector Unknown was designed from a task from the Inquiry-Oriented Linear Algebra (IOLA) curriculum to connect student's algebraic and geometric understandings of vector equations in linear algebra. In the game, users guide an avatar to a goal location by selecting vectors and scaling them. This research utilizes the game as realistic basis for supporting student understanding of 2D space structured by linear combinations, which may provide crucial intuitions between concepts such as span, linear independence, basis, and abstract vector spaces. Six participants were chosen from a large Southern university with a variety of gaming experience and no linear algebra experiences. The participants were paired into three groups based upon game experience (a gamer/gamer group, a gamer/non-gamer group, and a non-gamer/non-gamer group). Participants played and analyzed the game Vector Unknown to understand its mathematical design over the course of two approximately 60-minute interviews. During a third 60-minute interview, participants were then asked to design their own version of 3D version of the game to see how their reasoning about linear combinations in 2D space extends to higher dimensions. I conducted an analysis of the student's activity and found that students had four main themes for structuring space including structuring by design, structuring by generating, structuring across dimensions, and structuring all possible goals. I also found that viewpoint played an important role in student's connecting 2D and 3D space and include a viewpoint analysis linking differing viewpoints in GeoGebra to student activity.

ABSTRACT: The frontoparietal control network has been established as crucial in the successful implementation of cognitive control. Specifically, regions within the prefrontal cortex (PFC) have been shown to support the ability to flexibly coordinate demands of the external environment with internal goals. However, there is debate as to how these regions are functionally organized and if some regions are more influential than others within the network. One class of hypotheses theorize the PFC is hierarchically organized where regions higher in the hierarchy are presumed to exert more influence over the network. Within this class however, there is further debate as to which region is the most influential and thus the top of the hierarchy. Specifically, the lateral frontal pole (FPl) and the middle frontal gyrus (MFG) have been suggested to be at the top by two competing hierarchical models. The goal of this study was to provide a causal test of these hypotheses using transcranial magnetic stimulation followed by fMRI. Continuous theta burst stimulation (cTBS) was applied to either the FPl, MFG, or a control site (S1) followed immediately with fMRI in a within-subjects, cross-over design. Preliminary results show that MFG-cTBS significantly altered cognitive control-related activations throughout the PFC more than when targeting the FPl or control site. These preliminary results support that the MFG is an area of high influence consistent with an apical role in control. The MFG may therefore be a critical intervention target for modulating cognitive control.

ABSTRACT: This paper introduces asoptiso, which is an assembly optimizer error isolator. asopt is an assemblyoptimizer for a set of new ISAs, called the SCALE ISAs, and is a tool which is significantly difficult to debug when it produces erroneous assembly-optimized code that fails to correctly execute during simulation. asopt is difficult to debug due to two reasons. First, simulations can often take a long time to test the execution of assembly-optimized code. Second, there are often a large number of transformations which asopt has applied to the program, any of which could be the cause of error. Manually searching for the erroneous transformations among all applied transformations is highly impractical. I have created asoptiso to automate and simplify the process of isolating the first erroneous transformation applied by the assembly optimizer. This tool has proved extremely useful in speeding up the testing of asopt by not only automating error isolation, but also providing the user with a variety of useful features.

ABSTRACT: Animals can easily develop new food preferences and aversions through associative learning. If they consume a novel flavor and experience malaise, they develop an aversion towards that particular flavor, food or fluid. Conditioned taste aversion (CTA) requires gene expression and histone acetylation, which can be enhanced by HDAC inhibitors such as sodium butyrate (NaB). Here, I sought to determine whether enhancement of CTA using NaB is subject to sex-specific differences through changes in histone modification. Adult male (n=32) and female (n=32) Sprague-Dawley rats were placed on water restriction for 7 days with ad lib food to ensure intake on conditioning day. On the conditioning day, they were given 30 min access to saccharin (0.125%) and then injected with either sodium chloride (NaCl) or lithium chloride (LiCl; 0.15M, 3ml/kg). Ten minutes later, half the rats were injected with NaB (0.3M, 12ml/kg) or NaCl (0.3M, 12ml/kg. Thus, there were 4 groups for each sex: NaCl-NaCl, NaCl-NaB, LiCl-NaCl, and LiCl-NaB. Beginning the next day, 2-bottle 24-h preference tests of water vs. saccharin was carried out for 10 days. NaCl-NaCl and NaCl-NaB groups showed high preference for saccharin throughout 2-bottle testing. Male LiCl-NaCl showed moderate CTA which extinguished over the 10 days of preference testing. Male rats injected with LiCl-NaB appeared to have a greater CTA than LiCl-NaCl rats. However, NaB did not appear to enhance CTA in the LiCl-NaB-injected females compared to LiCl-NaCl injected rats. Thus, female rats appear to be less sensitive to the CTA-potentiated effects of NaB. I wanted to check if the effect of NaB is generalizable and if there is a hormonal influence in female rats blunting the NaB-mediated conditioned taste aversion. Therefore, I used another HDAC inhibitor sodium valproate (Val) to see if I get similar results. For this experiment, I used adult male (n=20) and female (n=20) rats and found that at 100mg/kg of Val, similar to observations with NaB, LiCl-induced CTA was enhanced in male rats but not in female rats. Next, I wanted to test the role of estrogen in female rats. For this experiment I used 36 adult female rats. I divided them into three groups where the first group of rats were ovariectomized, the second group were ovariectomized with estradiol pellet implant, and the third group had a sham surgery with intact ovaries. I found that CTA was not enhanced in ovariectomized with estrogen pellet group. Finally, I assessed if the sex differences were due to a difference in basal HDAC activity between males and females, by using adult male (n=4) and female (n=4) rats and found that the males had a higher HDAC activity in brainstem and amygdala than females and also female rats are less sensitive to HDAC inhibitors.

ABSTRACT: This dissertation brings together two independent studies that examine marginalized groups of entrepreneurs being affected by different types of external shocks. In this work, I define as marginalized groups individuals that are socially, institutionally, culturally, and/or resourcefully marginalized (Pidduck & Clark, 2021) and external shock as events that drastically affects the economy, either negatively or positively (Shepherd et al., 2000).Both studies are novel contexts. One involves marginalized entrepreneurial actors, doubly-stigmatized, the poor with disabilities, after the passage of a law designed to enhance their employment and self-employment, acting as a positive external shock. The second project examines marginalized entrepreneurial actors of different races in a unique time period created by a massive global external shock, during the COVID-19 pandemic. In the first essay of this dissertation, I investigated whether facilitating the transition of persons with disabilities to self-employment could improve their economic inclusion and well-being. I exploit the effects of a positive external shock, the implementation of the Inclusion of People with Disabilities Act in Brazil during early 2016. Using a sample of 2,555 persons with disabilities (16,802 individual-years from 2013 to 2019) after the implementation of the law, the odds of self-employment were 1.03 times higher (small effect sizes), and the self-employed did not achieve improvements in income. The findings did not differ by age, sex, education, or race. The findings have implications for policy makers aiming to improve self-employment outcomes for persons with disabilities. In the second essay, drawing on minority enclave theory and resilience theory in entrepreneurship, I test whether, with the onset of the COVID-19 pandemic, the self-employed lost more hours than the employed and whether traditionally disadvantaged self-employed racial minorities faced harsher penalties in the form of reduced hours of work. Though spatially concentrated ethnic minority colocations could improve business outcomes in the non-crisis period, with the pandemic affecting all the members in the enclave, the very dependencies in minority enclaves could be a liability. Using a large-scale survey during the COVID-19 pandemic conducted by the Brazilian government, I draw on a one-to-one nearest neighbor matched pair sample of 19,626 employed (public or private sector) and self-employed individuals, and control for industry-sector-interview-location fixed effects. The results show that self-employed people, compared to employed, reported a greater loss of hours. At the sample level, black self-employed people on aggregate lost 9,051 hours per month, and mixed-race self-employed people on aggregate lost 27,880 hours per month. The disproportionate loss of work hours by the self-employed from racial minority groups during the COVID-19 pandemic in a developing country context calls for a closer examination and assessment of the long-term impact of COVID-19 on racial minorities. In combination, the results of this dissertation have implications for entrepreneurship research, with unique examples of application of entrepreneurship research to two novel contexts. Where previous research documents that entrepreneurship is an important mechanism for poverty alleviation, I find that it may be of limited value in marginalized groups. Poor entrepreneurs in marginalized groups were found to gain the least from positive shocks and lose the most from negative ones.

ABSTRACT: In comparison to their lanthanide counterparts, the actinide elements are woefully understudied. This is especially true for the trans-plutonium actinides. Known isotopes of the heavier, later actinides possess, in most cases, shorter half-lives relative to the lighter actinides in addition to being more radiotoxic. These issues present significant complications when attempting to collect experimental data regarding the reactivity and bonding characteristics of the trans-plutonium actinides. Studying these elements through computational methods is made similarly difficult in part due to complex variables such as relativity and electron correlation. In light of this, it might seem easier to simply describe the actinides and their behavior as equivalent to that of the lanthanides as the Actinide Concept proposed by Glenn T. Seaborg suggests. However, advances in synthetic methods for handling these rare elements have resulted in the gathering of experimental evidence that, in combination with ever-improving computational methodology, indicate that the behavior of the later actinides does not mirror that of the later lanthanides. This is especially highlighted by the anomalous stabilization of the divalent oxidation state of the later actinides beginning at californium (Z = 98) and increasing onward to nobelium (Z = 102) which is, in fact, most stable in its divalent state at ambient conditions. A similar trend is not observed for the analogous lanthanide congeners of these actinides, and the implications of this phenomenon have been notably relevant for the separation of actinide elements from one another since the discovery of nobelium. Thus, a more thorough understanding of the unique behavior of the later actinides is crucial to understanding why they deviate from the periodicity exhibited by much lighter elements. At present, californium represents the heaviest actinide that synthetic inorganic chemistry can be achieved with and stands as the best option for investigating the nature of the divalent state of the later actinides.Chapter 1 of this work presents a detailed introduction to the typical behavior of the lanthanides and actinides under ambient conditions. An ensuing discussion of the issue of spent nuclear fuel containing many of the later actinides as fission products provides significant reason to understand the subtleties of the behavior of these elements, including the stabilization of the divalent oxidation state, for the development of more efficient separation methods. Given the scarcity of later actinides and difficulty in obtaining them, it is necessary to identify lanthanides that most closely model the behavior of the later actinides. Hence, the proposal and execution of work pertaining to optimizing the stability of relevant divalent lanthanide analogues with organic macrocycles is presented as well as the subsequent californium studies utilizing what was learned through studying the divalent lanthanides. Chapters 2, 3, 4, and 5 detail the experiments performed to explore the interactions of divalent lanthanides like Sm, Eu, and Yb (with special emphasis on Sm) with macrocycles like cryptands and crown ethers from the direct synthesis of LnI2 with these macrocycles in organic media under an inert atmosphere, where Ln = Sm, Eu, and Yb. These studies outline robust syntheses and crystallization methods for the respective divalent lanthanide complexes presented in each chapter. In addition, the properties of the isolated compounds are characterized through various spectroscopic techniques, magnetic studies, and computational results. Chapters 6 and 7 investigate more exotic chemistry with the divalent lanthanides. The former describes the crystallization and characterization of a Dy2+ 18-crown-6 complex while the latter explores the stability of Sm2+ under non-ideal conditions. Chapters 6 and 7 establish the potential to expand the concepts presented in chapters 2, 3, 4, and 5 to more intricate systems which is vital when exploring the more complex actinides. Finally, chapter 8 is a discussion of the culmination of the work in the previous chapters as it is applied to trans-plutonium actinides such as Am and Cf. In the case of Cf, a mixed valent Cf3+/Cf2+ compound was isolated using 18-crown-6 as the stabilizing ligand. Methods used for the synthesis of the starting material and reduction of the trivalent Cf precursor in chapter 8 have yielded more successful results than previous attempts. In addition to the first crystallographic evidence of divalent californium, this work serves as the template for the eventual isolation of the first bulk Cf2+ compound. Finally, chapter 9 is a summation of this body of work and its implications for further exploration of the unique behavior of the trans-plutonium actinides.

ABSTRACT: From inside our bodies to the environment we live in, there are a wide variety of unknown compounds that have been difficult to identify and characterize through current methods. We aim to study these compounds by liquid chromatography (LC) high-resolution tandem mass spectrometry (MS/MS). LC-MS/MS has become the gold standard for the analysis of complex mixtures due to its capabilities to decrease spectral overlap and high mass measurement accuracy. Proteins are of particular interest biologically because they give insight into various diseases and the health of our biological processes. Analysis of these proteins is hindered by the current methods implemented in laboratories due to the size and characteristics of these compounds and their natural behavior outside of biological systems. Just as import as what is inside the human body is what is in the environment, specifically the Earth's oceans. Just like proteins in the body, the Earth's oceans give us a picture into the health of the environment. We know that human activity has severally impacted our atmosphere and water sources. We aim to understand the connections with pollution and the effects it has on oceans, a major water source on Earth. First a broad overview of LC-MS/MS is presented in Chapter 1. The first section discusses the MS instrumentation used for the studies in the following chapters, the 14- and 21-Tesla Fourier Transform Ion Cyclotron Mass Spectrometer (14- and 21-T FT ICR MS). The custom-built system is designed to produce the highest resolution data for compound identification and structural information. Our facilities are also equipped with various liquid chromatography (LC) systems that are used to separate mixtures and decrease sample complexity. Lastly, a brief introduction to various complex mixtures analyzed by LC-MS. The chapters that follow cover the specific studies performed with the knowledge of LC-FT ICR-MS and compound identifications. Chapter 2 discusses a study into the benefits and limitations on the application of isotopic depletion for cultured proteins. Isotopic depletion is a method used to deplete compounds of various heavy isotopes of elements present, most commonly carbon, nitrogen, hydrogen, oxygen, and sulfur. Heavy isotopes effect MS experiments in multiple ways which are investigated in the study for proteins derived from multiple cell lines (E. coli and C. elegan). This work is novel in the application and analysis of isotopically depleted C. elegans proteins The methods used for the biological applications can be applied to the analysis of marine samples which is discussed in Chapters 3 and 4. Chapter 3 investigates the composition of sinking particles in the California Coastal Current, specifically metabolites. Sinking particles play a role in the regulation of biological processes in the water column but additionally have shown to regulate greenhouse emissions. We take an even deeper look with analysis of marine sediments to see how far pollutants travel down the water column and are stored at the bottom of the ocean, in Chapter 4. Marine sediment samples were collected from the Oregon continental shelf at established sample stations. The analysis of these environmental samples by LC-MS/MS is still in the developmental phase. Our work aims to develop novel LC-MS/MS methods that can give a fuller picture into environmental impacts of pollution. The overall goal is to expand the capabilities of LC-MS/MS experiments to complex mixtures. LC-MS/MS shows its true capabilities and potential in the experiments discussed here. From 300 Da to 40 kDa in size, LC-MS/MS can efficiently analyze a wide dynamic range of compounds which is critical to broad applicability. With this work, future experiments can analyze and identify a wide range of compounds by high-throughput LC-MS/MS analysis.

ABSTRACT: The purpose of this study was to explore the extent to which university-level choral faculty experience impostor feelings across job responsibilities (conducting, teaching, and research), years of experience, and gender. Individuals experiencing impostor phenomenon (IP) are typically high-achieving, successful people, yet tend to feel that they are undeserving of their success and fear exposure as a fraud. Participants (N = 206) were university faculty members who held choral music education, choral conducting, or hybrid positions. They responded to a survey that included the Clance Impostor Phenomenon Scale (CIPS; Clance, 1985) and three researcher-modified CIPS for conducting, teaching, and research. Results indicated that a majority of choral faculty experience IP in at least one category, with participants feeling the highest impostor feelings regarding their research expectations and abilities. Participants reported the lowest level of IP feelings in regard to teaching. In investigating the relationship between teaching experience and IP feelings, there were significant correlations with all four scales. There was a weak, negative association between years of experience and general IP feelings, years of experience and conducting, and years of experience and teaching. There was a moderate, negative relationship between years of experience and research. Finally, results indicated no significant difference between gender and any scale category. In addition to these results, descriptive statistics for IP feelings in each category revealed high standard deviations. This finding suggests that impostor feelings are highly individualistic and can present differently based on personal experiences.

ABSTRACT: Autonomous vehicle (AV) is becoming very popular due to technological evolution in autonomous transportation sector. It can be more reliable than human-controlled vehicle as it can detect pedestrians with high accuracy and control the vehicle precisely. One major disadvantage of the autonomous vehicle is that it cannot communicate with surrounding pedestrians and other road users like a traditional vehicle. Pedestrians tend to interact with human drivers before taking a crossing decision; but AV cannot use such communication mediums. As a result, it is necessary to understand how pedestrians will behave in a crossing scenario when an AV is present. To evaluate this complex interaction pattern, a simulation tool can be useful as it can generate realistic pedestrian motion models which are useful to design different AV algorithms. These motion models can also help to understand different perspectives from a pedestrian viewpoint and what factors are related to the safe interaction between AVs and pedestrians. It can also benefit autonomous vehicle designers: they can visualize pedestrian and vehicle trajectories, extract velocity and acceleration profile of both agents, test different autonomous vehicle planning algorithms and assess the traffic safety in severe traffic conflicts. This research work presents a rule-based social force model to simulate pedestrian trajectories during interaction with an autonomous vehicle. The social force model is then integrated with an autonomous vehicle control and planning algorithm for simulating the behavior of both pedestrian and vehicle in traffic conflicts by varying different parameters such as agent's initial speed, different vehicle sensor types (error percentage of pedestrian detection varies), different pedestrian types (risk-taking, cautious and distracted), etc. Two types of crossing scenarios (crosswalk and roundabout) are used in this research work. The output of this simulation is the minimum distance that is accepted by a pedestrian during crossing. These minimum distances can be used to simulate more risky interaction scenarios to understand the effectiveness of autonomous vehicle planning algorithm while interacting with different types of pedestrians. Although AVs are expected to reduce traffic crashes, a finite element simulation model is developed to determine pedestrian risk injury criteria for both head and chest portion during unavoidable crashes. The finite element model uses side and frontal impact for pedestrian collision. Injury probability for both head and chest injuries are found higher for the frontal impact than the side impact collision.
