Divided-Tenure, Divided Recovery: How Policy and Land Tenure Shape Disaster Recovery for Mobile Homeowners

People who live in mobile homes have heightened vulnerability to disasters, due in part to mobile homes increasingly occupying high-hazard risk lands and the precarious ownership status known as divided-tenure. Divided-tenure is when an individual owns a mobile home and rents the land underneath. To identify the challenges associated with divided-tenure and disaster recovery from a policy perspective, this study analyzed the content of key HUD policies and performed a comparative policy analysis of purchase opportunity laws (requirements of landowners to give mobile homeowners an opportunity to purchase the property their home resides on) in three states: California, Florida, and New York. Content analysis indicated few direct references to mobile homes. Inconsistencies and confusing messaging were found in the existing federal guidance. The lack of consistent terminology and guidance on addressing divided-tenure, limits mobile homeowner's options for disaster recovery, including eligibility for federal disaster aid and potentially participation in relocation or buyout programs. The three selected states' purchase opportunity laws reviewed in this study were rated as weak. Policies lacked alignment with federal documents and opportunities for mobile homeowners were difficult to navigate. A pathway to land ownership could give mobile homeowners more control over their disaster recovery options, but …

Oklahoma History

Oklahoma History is a collection of poetry that examines the speaker's relationship to and critique of her home state, Oklahoma. The poems navigate race and gender as they intersect with local histories, culture, and religion, which complicates and often contradicts what the speaker is taught through childhood, adolescence, and into adulthood. The creative portion is accompanied by a critical preface which looks at how the poems and other writings of Oklahoma poet Joy Harjo impact the author's writing.

Involving Children in the Assessment Process: Experiences of a Developmentally Appropriate Feedback Model

Assessment is a foundational part of counseling practice, which includes the process of providing assessment feedback to those tested. Millions of children are assessed across the United States through the public-school system, hospital, agency, and private practice settings. Though millions of children are assessed yearly, there has been little research surrounding providing assessment feedback with children. In this study, the author qualitatively explored children's experiences with a developmentally appropriate feedback model, the young children's assessment feedback (YCAF). Participants included ten 6 to 10-year old children, who had not previously gone through psychoeducational testing within the last year. Participants completed a battery of psychoeducational assessments and the YCAF feedback process. Data sources included session transcriptions, session observation notes, child interviews, parent interviews, and expressive arts observation notes. In order to explore the perceptions regarding the YCAF, the author utilized interpretative phenomenological analysis to understand the children's feedback experiences. Findings included the following themes: freedom for self-direction, self-concept, therapeutic relationship, affective responses of child, systemic shifts, and developmental considerations. The themes show that the children in this study saw a variety of benefits and experiences surrounding receiving their own personalized, developmentally appropriate assessment feedback.

Development and Exploration of End-User Healthcare Technology Acceptance Models

This dissertation consists of three studies that collectively investigate the factors influencing the consumer adoption intention towards emerging healthcare technologies. Essay 1 systematically reviews the extent literature on healthcare technology adoption and serves as the theoretical foundation of the dissertation. It investigates different models that have been previously applied to study healthcare technology acceptance. Meta-analysis method is used to quantitatively synthesize the findings from prior empirical studies. Essay 2 posits, develops, and tests a comprehensive biotechnology acceptance model from the end-user's perspective. Two new constructs, namely, perceived risk and trust in technology, are integrated into the unified theory of acceptance and use of technology. Research hypotheses are tested using survey data and partial least square – structural equation modeling (PLS-SEM). Essay 3 extends the findings from the Essay 2 and further investigates the consumer's trust initiation and its effect on behavioral adoption intention. To achieve this purpose, Essay 3 posits and develops a trust model. Survey data allows testing the model using PLS-SEM. The models developed in this dissertation reflect significant modifications specific to the healthcare context. The findings provide value for academia, practitioners, and policymakers.

Bringing Them Back: Using Latent Class Analysis to Re-Engage College Stop-Outs

Half of the students who begin college do not complete a degree or certificate. The odds of completing a degree are decreased if a student has a low socio-economic status (SES), is the first in a family to attend college (first-generation), attends multiple institutions, stops out multiple times, reduces credit loads over time, performs poorly in major-specific coursework, has competing family obligations, and experiences financial difficulties. Stopping out of college does not always indicate that a student is no longer interested in pursuing an education; it can be an indication of a barrier or several barriers faced. Institutions can benefit themselves and students by utilizing person-centered statistical methods to re-engage students they have lost, particularly those near the end of their degree plan. Using demographic, academic, and financial variables, this study applied latent class analysis (LCA) to explore subgroups of seniors who have stopped out of a public four-year Tier One research intuition before graduating with a four-year degree. The findings indicated a six-class model was the best fitting model. Similar to previous research, academic and financial variables were key determinants of the latent classes. This paper demonstrates how the results of an LCA can assist institutions in the decisions …

A Study of Anomalous Conduction in n-Type Amorphous Silicon and Correlations in Conductivity and Noise in Gold Nanoparticle-Ligand Arrays

This work explores two very different structural systems: n-type hydrogenated amorphous silicon (a-Si:H) and gold nanoparticles (AuNPs) suspended in a matrix of organic ligands. For a-Si:H, examination of the gas-phase concentration of dopant (1-6% PH3/SiH4) and argon diluent effects includes the temperature dependent conductivity, low-frequency electronic noise, and Raman spectroscopy to examine structure. It is found that a-Si:H samples grown with high dopant concentration or with argon dilution exhibit an anomalous hopping conduction mechanism with an exponent of p=0.75. An experimental approach is used to determine correlations between conduction parameters, such as the pre-exponential factor and the characteristic temperature, rather than an analysis of existing models to explain the anomalous conduction. From these results, the anomalous conduction is a result of a change in the shape of the density of states and not a shift of the Fermi level with dopant. Additionally, it is found that argon dilution increases the carrier mobility, reduces the doping efficiency, and causes a degradation of the short-range order. With AuNPs, a comparison of temperature dependent conductivity and low-frequency noise shows that the temperature coefficient of resistance (TCR) is independent of the length of interparticle distance while the noise magnitude decreases.

Wildfire Influence on Rainfall Chemistry and Deposition in Texas during the 2011-2014 Drought

From 2011 to 2014, one of the most severe and intense droughts in Texas recorded history led to widespread wildfires across the state, with unknown effects on atmospheric nutrient and pollutant deposition. The objectives of this research were to: (1) characterize the frequency, magnitude, and spatiotemporal distribution of Texas wildfires (2011-2014); (2) identify smoke occurrence and source regions at eight Texas National Atmospheric Deposition Program (NADP) National Trends Network (NTN) sites (2011); and (3) quantify the influence of wildfire on weekly rainwater chemistry and deposition in 2011 at three NADP sites (Sonora, LBJ Grasslands, Attwater Prairie NWR). Data on large wildfires, smoke occurrence, and rainfall chemistry and deposition were coupled with principal component and back-trajectory analysis to address these objectives. Between 2011-2014, 72% of all wildfires occurred in 2011, accounting for 90% of the total area burned. In total, there were 17 extreme wildfires (i.e., in the 95th percentile of hectares burned), of which 11 occurred in 2011. Wildfire activity was concentrated in West Texas ecoregions and consumed primarily shrub/scrub and grassland/herbaceous land cover. Although West Texas experienced the most wildfires, smoke at the NADP locations in 2011, the "high-fire year," was more frequent in East Texas due to regional …

"It Seems Like It's Never Going to End": The Experiences of Those Living in Damaged Dwellings Following Hurricane Sandy

Where people go between evacuation and recovery remains an understudied aspect of disaster research. Whether experiencing multiple displacements, permanent displacement, or undergoing recovery in a damaged dwelling, the spatial and temporal dimensions of disaster displacement can have direct impacts on the recovery experiences of survivors. Pulling from focus group data gathered in 2017 from Hurricane Sandy survivors in New Jersey, this qualitative research focuses on the experiences of those who recovered in-situ, or within their damaged dwelling following the storm, and the various ways this non-displacement impacted their recovery. A content analysis following a grounded theory approach produced the emergent themes of the in-situ experience, including: a lack of suitable shelter, an exposure to secondary hazards, and an inability to achieve satisfactory emotional recovery. This study contributes to the growing body of literature surrounding recovery experiences, and it introduces valuable insights into the challenges that survivors face while recovering in-situ.

François Couperin's Neuvième Concert, "Ritratto Dell' Amore": A Performance Guide and Edition for Flute and Keyboard

François Couperin (1668-1733) was one of the earliest French Baroque composers to merge the Italian style into the French tradition. He had great influence on the development of French Baroque music from the end of the seventeenth century until his death. Couperin's four Concerts Royaux and the ten Concerts Nouveaux (published in 1722 and 1724) were written for the enjoyment of Louis XIV. Those suites were popular in the court before they were published, as they were requested to be performed every Sunday during the years 1714 and 1715 to give pleasure to the king. Rittrato dell'amore is the ninth suite out of the fourteen suites. The purpose of this study is to provide a performance guide and a practical edition of François Couperin's Neuvième Concert Ritratto dell' amore. It also contrasts Italian style and French tradition in the Baroque period, and how Couperin blended both styles together in his Neuvième Concert. In addition, this dissertation summarizes the general principles of Baroque performance practice that one may encounter in Neuviéme Concert, including notes inégales (unequal notes), ornamentation, over-dotting, and other issues. It is especially important for one to understand the performance style of French Baroque music in order to perform …

A Genetic Assessment of the Mating System of a Suburban Red-Shouldered Hawk Population in Southwest Ohio

Considering the high reproductive investment of the social male and the cost to the female of losing this benefit by soliciting copulations outside the social pair bond, it is expected that most raptor populations would exhibit low to no occurrence of extra-pair paternity (EPP). This holds true for the majority of raptor species studied to date with only one exception of an urban Cooper's hawk (Accipiter cooperii) study which reported an unexpectedly high extra-pair young frequency of 19.29%. In our study we examined the frequency of EPP within a red-shouldered hawk (Buteo lineatus) population residing in the suburban/urban matrix of southwest Ohio. During the breeding seasons of 2018 and 2019, 181 breeding age and nestling individuals were color-banded and sampled for genetic analysis using nine microsatellite loci. After genotyping a total of 40 broods (with at least two nestlings per brood) and both presumptive parents of each brood, no clear evidence of EPP was detected. However, at one nest site, the entire brood of four chicks was not sired by the adult male observed during the courtship period, nor another adult male observed tending the chicks later in the season. We suspect that this particular nest represented two instances of …

Sustaining Multilinguality: Case Studies of Two Multilingual Digital Libraries

Digital libraries have become valuable learning resources for information users. However, language barriers have greatly limited information access for many digital libraries, as users do not understand those languages. This study explored technical and operational challenges digital libraries faced in sustaining multilinguality. Using the multiple-case method, the study investigated two digital libraries that have sustained multilinguality for over a decade: the World Digital Library and the Digital Library of the Caribbean. On-site interviews were conducted at both digital libraries and the related documents were analyzed. The findings of the study showed that the two multilingual digital libraries faced many technical and operational challenges and employed various approaches to find solutions. A model of challenges and approaches in sustaining multilinguality was presented. As the first such case study, this research enriches the existing literature, and has theoretical, practical, and methodological implications for the research of multilingual digital libraries. The findings of the study provide useful guidelines and insights for the digital library community in sustaining multilingual services.

The Artistic Image in "Twelve Children's Pieces of Medium Difficulty," Op. 31 by Reinhold Gliere (1875–1956)

In his Art of Piano Playing, the renowned Russian pianist and teacher Heinrich Neuhaus asserts that the concept of an "artistic image" can give musical meaning to the score, help pianists to understand the musical content of a composition, and help students to find pianistic expression in the details. The concept of artistic image can be applied in pedagogy, guiding young pianists to learn content and organize their practice. The artistic image is the picture of a musical idea and the musical language, which comes from melody, phrasing, musical structure, and the emotional and poetic content. Twelve Children's Pieces of Medium Difficulty, Op. 31, is one of the important works for young pianists by Reinhold Glière (1875–1956). The set has emotional characteristics that allow intermediate young pianists to grasp its rich content and then develop technically. His piano works have been little studied by scholars as part of a pedagogical approach. This pedagogical guide uses the concept of artistic image in Glière's work to help young pianists, or their teachers, prepare this work thoroughly and perform it successfully on the stage.

Apprenticeship to Signs in Art Education

This research looks thoughtfully and deeply at the relationship between art education and signs, as defined by the French philosopher Gilles Deleuze (1964/1998). Signs, as articulated by Deleuze (1964/1998), are violent disruptions to our way of understanding the world, causing us to think again and/or re-consider what we once knew (or thought we knew). This study looks generatively at how these kinds of disruptive and disorienting moments might be mined for possibilities in art education and remind us of our own relationality. As a post-qualitative lived inquiry, it asks how might art education be-with apprenticeship to signs and what might art education do-with sign-encounters? Using the theoretical lens of transcendental empiricism and new materialism, this study considers how art educators might hold open the space of sign-encounters for oneself and one's students by turning towards the rhizomatic cut and staying with uncertainty. It is focused on the doing-with, making-with, and thinking-with of art, pedagogy, and philosophy/theory, investigating their deep entanglements in spaces of disruption and ultimately developing frame-works for engaging in this kind of work in the classroom. Drawing from Erin Manning and Brian Massumi's theory of research-creation, this research was experienced in an emergent, layered, and complex way over …

The Convolutional Recurrent Structure in Computer Vision Applications

By organically fusing the methods of convolutional neural network (CNN) and recurrent neural network (RNN), this dissertation focuses on the application of optical character recognition and image classification processing. The first part of this dissertation presents an end-to-end novel receipt recognition system for capturing effective information from receipts (CEIR). The main contributions of this research part are divided into three parts. First, this research develops a preprocessing method for receipt images. Second, the modified connectionist text proposal network is introduced to execute text detection. Third, the CEIR combines the convolutional recurrent neural network with the connectionist temporal classification with maximum entropy regularization as a loss function to update the weights in networks and extract the characters from receipt. The CEIR system is validated with the scanned receipts optical character recognition and information extraction (SROIE) database. Furthermore, the CEIR system has strong robustness and can be extended to a variety of different scenarios beyond receipts. For the convolutional recurrent structure application of land use image classification, this dissertation comes up with a novel deep learning model for land use classification, the convolutional recurrent land use classifier (CRLUC), which further improves the accuracy in classifying remote sensing land use images. Besides, the …

SIMON: A Domain-Agnostic Framework for Secure Design and Validation of Cyber Physical Systems

Cyber physical systems (CPS) are an integration of computational and physical processes, where the cyber components monitor and control physical processes. Cyber-attacks largely target the cyber components with the intention of disrupting the functionality of the components in the physical domain. This dissertation explores the role of semantic inference in understanding such attacks and building resilient CPS systems. To that end, we present SIMON, an ontological design and verification framework that captures the intricate relationship(s) between cyber and physical components in CPS by leveraging several standard ontologies and extending the NIST CPS framework for the purpose of eliciting trustworthy requirements, assigning responsibilities and roles to CPS functionalities, and validating that the trustworthy requirements are met by the designed system. We demonstrate the capabilities of SIMON using two case studies – a vehicle to infrastructure (V2I) safety application and an additive manufacturing (AM) printer. In addition, we also present a taxonomy to capture threat feeds specific to the AM domain.

Investigating the Effects of Sketchnoting on Undergraduate Students' Learning Strategies

This study investigates the effects of sketchnoting, a visualized approach of notetaking, on learning strategies. The main questions asked were: What are the effects of sketchnoting on learners' learning strategies, including cognitive strategies (rehearsal, elaboration, organizational) and metacognitive strategies? Forty-eight undergraduate participants were divided into two groups, an experimental group, and a control group. Findings demonstrated a significant increase in cognitive learning strategies and metacognitive strategies in the experimental group. Other findings revealed that the aesthetic appeal of sketchnoting is the major reason motivating participants' sketchnoting behavior and the corresponding connection between design strategies and the learning strategies is the key of positive impacts of sketchnoting on learning strategies. Additional insights and implications are discussed.

Unraveling the Effect of Atomic Configurations and Structural Statistics on Mechanical Behavior of Multicomponent and Amorphous Alloys

Multicomponent high-entropy and amorphous alloys represent relatively new classes of structural materials with complex atomic configurations and exceptional mechanical properties. However, there are several knowledge gaps in the relationships between their atomic structure and mechanical properties. Understanding these critical relationships will enable novel alloy design and tailoring of their mechanical properties for desired engineering applications. In this dissertation, first-principles calculations and molecular dynamics simulations are applied to investigate the local atomic configurations and ordering in high-entropy and amorphous alloys. Our findings suggest that fluctuations in local atomic configurations for high- entropy alloys result in significant changes in stacking fault energy, twin energy, dislocation behavior, dislocation-twin interactions, and critical shear stress. For amorphous alloys or metallic glasses, the short-range order (SRO) and medium-range order (MRO) were found to play decisive roles in determination of their mechanical properties. Structural relaxation was found to lead to shear localization, which was attributed to free volume change and evolution of SRO and MRO to more brittle nature. In contrast, rejuvenated metallic glasses had relatively large and uniform free volume distribution giving rise to homogeneous flow and increased plasticity.

Beethoven's Orchestra at the Romantic Piano: Understanding the Piano Transcriptions of "Marcia alla turca" from Beethoven's The Ruins of Athens by Franz Liszt and Anton Rubinstein

The transcriptions of Franz Liszt (1811-1886) and Anton Rubinstein (1829-1894) on Beethoven's "Marcia alla turca" serve as unique examples within the area of transcription since each of these important virtuosos transcribed the movement with drastically different results. Liszt's Capriccio alla turca (1846) is built on Beethoven's thematic materials although it is presented with a greatly embellished accompaniment providing countermelodies, expanded passages, and vigorous rhythmic features. In contrast, Rubinstein's Turkish March (1848) attempts to capture Beethoven's original (1811) as closely as possible adhering to the form and harmonies. Each composer's approach served to showcase new pianistic innovations capturing orchestral sonorities at the piano previously unimagined. This dissertation offers musical insight for two less well-known works from significant pianist-composers which should receive further attention. Additionally, this research provides greater documentation for the compositions of Rubinstein, supplementing the historical accounts of his abilities as a performer. Examination and comparative analysis of each transcription not only illuminates the creative approaches each composer employed in creating his transcription, but also serves pianists wishing to perform these neglected works.

Assessing the Clinical Experiences and Attitudes of Play Therapists Working with Children of Parental Substance Use

This study aimed to gain insight into the clinical practices and attitudes of currently practicing play therapists working with children with a parent with a substance use disorder. Participants in the study were play therapists credentialed by the Association for Play Therapy, either as a Registered Play Therapist™ or Registered Play Therapist-Supervisor™. A total of 198 play therapists participated in the study. Results demonstrated that variables including prior education, caseload of children affected by parental substance use, and the number of years since obtaining a mental health licensure explained 16% of the variance in participant attitude scores on the Drug and Drug Problems Perceptions Questionnaire (DDPPQ). Specifically, education (β = -.335, rs2 = .884, p < .001) was found to be a significant predictor of play therapist attitudes towards substance users as it explained 88% of the variance accounted for in the effect. Additionally, although not found to be significant, caseload (β = -.134, rs2 = .325, p = .058) was found to explain 33% of the variance accounted for in the effect. This initial exploration of play therapists' attitudes towards substance users provides strong evidence towards the importance of education and training in substance use disorders. Further exploration of …

Counting Plane Tropical Curves via Lattice Paths in Polygons

A projective plane tropical curve is a proper immersion of a graph into the real Cartesian plane subject to some conditions such as that the images of all the edges must be lines with rational slopes. Two important combinatorial invariants of a projective plane tropical curve are its degree, d, and genus g. First, we explore Gathmann and Markwig's approach to the study of the moduli spaces of such curves and explain their proof that the number of projective plane tropical curves, counting multiplicity, passing through n = 3d + g -1 points does not depend on the choice of points, provided they are in tropical general position. This number of curves is called a Gromov-Written invariant. Second, we discuss the proof of a theorem of Mikhalkin that allows one to compute the Gromov-Written invariant by a purely combinatorial process of counting certain lattice paths.

A New Class of Stochastic Volatility Models for Pricing Options Based on Observables as Volatility Proxies

One basic assumption of the celebrated Black-Scholes-Merton PDE model for pricing derivatives is that the volatility is a constant. However, the implied volatility plot based on real data is not constant, but curved exhibiting patterns of volatility skews or smiles. Since the volatility is not observable, various stochastic volatility models have been proposed to overcome the problem of non-constant volatility. Although these methods are fairly successful in modeling volatilities, they still rely on the implied volatility approach for model implementation. To avoid such circular reasoning, we propose a new class of stochastic volatility models based on directly observable volatility proxies and derive the corresponding option pricing formulas. In addition, we propose a new GARCH (1,1) model, and show that this discrete-time stochastic volatility process converges weakly to Heston's continuous-time stochastic volatility model. Some Monte Carlo simulations and real data analysis are also conducted to demonstrate the performance of our methods.
