Presentation discussing the End of Term Web Archive project and progress of moving EOT datasets to the AWS S3 cloud.

This dissertation consists of three studies that investigate the information privacy & security associated with healthcare technology use. Essay 1 PRISMA-style systematically reviews the existing literature on privacy information disclosure in IoT technology and serves as the theoretical foundation of the current research. It is crucial to comprehend why, how, and under what consequences individuals choose to disclose their personal and health information since doing so is beneficial to the company. This SLR method allows us to find those factors that significantly impact individuals' behavioral intention to disclose personal information while using IoT technologies. Essay 2 posits, develops, and tests a comprehensive theoretical framework built upon the theory of planned behavior and the health belief model to examine factors affecting willingness to disclose PHI in order to use WFDs. A research survey is designed and distributed to a crowdsourcing platform, Mechanical Turk (M-Turk). Research hypotheses are tested using partial least square – structural equation modeling (PLS-SEM). To achieve this purpose, Essay 3 extends the findings from the previous essay and further investigates the caregiver context. Therefore, we developed a novel theoretical model utilizing privacy calculus theory and the technology acceptance model to investigate the willingness of the elderly to disclose …

This dissertation examines the impact of trauma on information-seeking behaviors and decision-making processes. Essay 1 includes a qualitative analysis of the transcripts obtained from interviews with four military service members diagnosed with PTSD. The results showed that 75% of this small sample population exhibited addictive behavior that was presented in their information behaviors. All four members indicated that the excessive extent to which they seek information is related to the perceived importance of the information and their level of trust in the sources. Low trust in information sources increases the number of sources searched for validation in this population. Essay 2 involved the collection and analysis of survey data. The results of the stepwise backward regression show that two trauma variables (adult sexual assault, sudden fear) have a significant combined negative effect on decision-making in this population. The analysis and results of a different survey are presented in Essay 3. The stepwise logistic regression analysis results conducted on the summated scales developed showed a strong positive link between trust in scientific experts for scientific information and the dichotomous dependent variable trust in social media for news. The research conducted in this dissertation extends the understanding of how trauma affects people's …

Despite the evidence that supports the benefits of a holistic, collaborative approach to autism intervention, but there is little training to teach those skills to professionals. Behavior analysts working in applied settings will often partner with different individuals from very different backgrounds and disciplines. Skilled Dialogue has been recommended as an approach to conversations that values everyone's contributions in fostering compassionate, collaborative, and culturally responsive care to benefit the children served. The purpose of this study was to evaluate the effects of a training workshop to teach the concept and strategies of skilled dialogue to behavior analysts in training. The participants were taught and practiced using the six strategies of Skilled Dialogue: welcoming, allowing, sense-making, appreciating, joining, and harmonizing through use of instructions, rationales, activities, simulations, and feedback. The success of the training was evaluated using a multiple baseline design across training components. Audio and video responses to role-play scenarios were recorded, transcribed, and scored to measure the results of the training workshop on communication skills. The results suggested that the training workshop was an effective method to teaching future behavior analysts how to engage in the strategies and components of skilled dialogue, increasingly the likelihood of collaborative, and children …

The traditional definition of tourism has been transformed by significant advancements in communication and information technology. The concept of Metaverse, derived from the words "meta" (meaning beyond) and "verse" (meaning universe), has redefined how people experience travel. This innovative concept combines virtual reality, augmented reality, and artificial intelligence to create virtually augmented spaces. However, the tourism industry should clarify and narrow down the definition of Metaverse and its intriguing concept for its successful adoption in the future. Thus, it is crucial to define Metaverse tourism and understand how users will accept it in the near future. This study aims to comprehend the technology behind Metaverse tourism, review current research on the topic, and identify the critical factors related to experiential Metaverse tourism. The paper also examines how computer self-efficacy, novelty seeking, subjective norm, job relevance, perceived usefulness, perceived ease of use, and perceived enjoyment can influence expected user satisfaction and behavioral intention, given the context of situational motivation. The findings have significant implications for theory and management, addressing various questions related to users' perceptions, expectations, design considerations, stakeholder preparations, and performance assessment of metaverse technology in tourism applications.

The aim of this thesis is to advance the field of solid lubrication science by developing coatings that provide reliable performance in ambient conditions, work on rough surfaces, and are amenable to industrial size and design complexities. Two different coating systems, Ti3C2Tx-MoS2 and Ti3C2Tx-Graphene Oxide blends, were studied in this work. The Ti3C2Tx-MoS2 nanocomposites were spray-coated onto rough 52100-grade steel surfaces, and their tribological performance was evaluated in a ball-on-disk configuration in a unidirectional sliding mode. The test results indicate that Ti3C2Tx-MoS2 coatings achieved superlubricity, which has not been previously reported for either pristine material under macroscale sliding conditions. The observed synergistic mechanism enabled the superlative performance, which was explained by the in-situ formation of a robust tribolayer responsible for sustained lubricity even at high contact pressures (>1.1 GPa) and sliding speeds (0.1 m/s). Processing, structure, and property correlation studies were conducted to understand the underlying phenomena. Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy were used to reveal the formation of the tribolayer. The Ti3C2Tx-Graphene Oxide blends were also spray-coated onto rough-bearing steel surfaces, and their tribological assessment was carried out in ambient environmental conditions and high contact pressures in a ball-on-disc experimental setup. The coatings led to …

Effective and efficient skill-acquisition procedures must be identified to support individualized behavioral programming for children with autism spectrum disorder (ASD). To do this, practitioners and researchers may use assessment-based instruction. Prompts are a common teaching strategy to promote skill acquisition. The purpose of this applied study was to use assessment-based instruction to evaluate the efficacy and efficiency of within- and extra-stimulus prompts to teach conditional discriminations to two children with ASD. We identified stimulus prompts using a survey of popular children's games and conducted a tablet-based instruction readiness assessment. Stimulus prompts involved motion (within-stimulus) and pointing (extra-stimulus) to evoke correct responses in the presence of a discriminative stimulus. We used an adapted alternating treatments design with a no-treatment control condition to evaluate the effects of both prompt types across multiple sets of stimuli. Both stimulus prompt types were efficacious in facilitating skill acquisition for two of three participants. Little difference was observed in the time to mastery with either prompt. Neither stimulus prompt was efficacious for the third participant. Assessment results will be used to inform clinical programming to teach conditional discriminations to participants and contribute to research on designing and implementing assessments of skill-acquisition procedures.

This exploratory study investigated the relationship between attachment style and offense types of juvenile offenders to determine whether there were commonalities among the cohort and their attachment style. Much of the peer-reviewed literature focuses on adult sex offenders and attachment style but neglects the juvenile population. The present study utilized secondary data from the Texas Juvenile Justice Department (TJJD) which included adjudicated juveniles with Positive Achievement Change Tool (PACT) data (n = 4,521) from 2009 to 2013. Juveniles were grouped into three attachment groups (secure, anxious-avoidant, or other) based on attachment correlates found in their PACT data. Logistic regression analyses were then used to investigate the relationship between attachment styles and offense types among the adjudicated juveniles. Results indicated that attachment style does not have an overwhelming influence on offense type of juvenile offenders. However, juveniles with an attachment style other than secure or anxious-avoidant were more likely to be adjudicated for assault/aggravated assault, sexual assault/aggravated assault, aggravated robbery, and other offenses not captured. Whereas juveniles with an anxious-avoidant attachment are at increased odds of being adjudicated for drug offenses. However, it should be noted that juveniles adjudicated for sexual assault/aggravated sexual assault with an anxious-avoidant attachment style reflected a …

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

Interfacial mechanical properties of adhesive joints are very crucial in board applications, including composites, multilayer structures, and biomedical devices. Establishing traction-separation (T-S) relations for interfacial adhesion can evaluate mechanical and structural reliability, robustness, and failure criteria. Due to the short range of interfacial adhesion such as micro to nanoscale, accurate measurements of T-S relations remain challenging. The advent of machine learning (ML) became a promising tool to predict materials behaviors and establish data-driven mechanical models. In this study, we integrated a state-of-the-art ML method, finite element analysis (FEA), and standard experiments to develop data-driven models for characterizing the interfacial mechanical properties precisely. Macroscale force-displacement curves are derived from FEA with incorporation of double cantilever beam tests to generate the dataset for ML model. The eXtreme Gradient Boosting (XGBoost) multi-output regressions and classifier models are used to determine T-S relations with R2 score of 98.8% and locate imperfections at the interface with accuracy of around 80.8%. The outcome of the XGBoost models demonstrated accurate predictions and fast calculation speed, outperforming several other ML methods. Using 3D printed double cantilever beam specimens, the performance of the ML models is validated experimentally for different materials. Furthermore, a XGBoost model-based package is designed to …

In the US, rural Native American communities (RNACs) experience excess morbidity in mental health disorders and mortality from opioid use disorder (OUD). This study used mixed methods to evaluate and analyze the primary data from 76 healthcare providers (HPs) from 24 states across the US (physicians = 7%), to identify HP knowledge and training regarding available prevention, treatment, and recovery (PTR) programs in treating OUD, assessment and management skills, and networking and collaboration capacity among the RNACs they serve. The HP completed the Opioid Survey for Health Care Providers online. A majority of HPs reported a need for knowledge and training regarding OUD treatments (92%). Less than half of the HPs provide intensive outpatient treatment; 40% contracted out for medication assisted treatment/medications for opioid use disorder (MAT/MOUD) services. Recovery support was low at 33% for adults and 38% for youth. HPs reported use of Narcan to be effective in reversing overdose (87%). Qualitative responses supported survey findings and described barriers, including lack of resources, inadequate staffing, insufficient funding, lack of training and OUD knowledge, stigma, and lack of tribal involvement and support. The study findings indicate HPs' need for information and training about OUD and networking and collaboration of healthcare …

By combining organizational analysis and consumer research, this research draws on anthropological principles to explore the nuances of family governance and their effects on behavior, customer experience, and product design. The results of this study present insightful information on product perception and actionable strategies to improve product design, branding, and messaging in order to enhance customer experience and drive sales. Drawing on organizational anthropology and the utilization of critical reflexivity, this thesis provides a deeper understanding of how family-owned businesses can leverage research to challenge their cultural assumptions about products, consumers, and their organization, in order to effectively implement customer-centric solutions and drive organizational behavior, customer experience, and product development.

Extant research suggests communication styles (CS) such as constructive communication (CC) to be associated positively with relationship satisfaction (RS) and negatively with mental health (MH) whereas self-demand / partner withdraw (SD/PW) communication is associated negatively with RS and positively with MH. Research also suggests child abuse (CA) to be associated with poorer CS, lower RS, and poorer MH. Further, RS has been differentially associated with MH and CS in adult intimate relationships. However, no study has examined these associations simultaneously. The current study aimed to (1) assess these associations in IPV-exposed women and (2) assess differences between those with and without a history of CA. Data (n = 412; Mage = 36.77, SD = 12.54) come from a larger data collection project (N = 676). I hypothesized that: (1) higher CC and RS would be associated with lower severity of MH symptoms; (2) higher SD/PW and lower RS would be associated with higher severity of MH symptoms; (3) women with a history of CA will report less CC, lower RS, and higher severity of MH symptoms; and (4) women with a history of CA will report more SD/PW, lower RS, and higher severity of MH symptoms. Results did not support …

In this study, high-fidelity conjugate heat transfer simulations are used to model a micro-channel heat exchanger (MCHE) in a crossflow to study its thermal-hydraulic performance. This study considers three different microchannels (internal flow) geometries (circular, triangular, and square) with louver-shaped fins. The local flow field showed a strong coupling between the microchannel flow, solid domain, and crossflow. The flow separation and wake regions formed near MCHE resulted in a large variation in the velocity field and temperature in the crossflow. The wake region had a significant spanwise variation due to its interaction with fins, which also causes variations in the thermal boundary layer. The heat conduction in the solid structure provided a non-uniform temperature field with a higher temperature near the microchannel and a slightly lower temperature near the surface exposed to the crossflow. The microchannel flow analysis showed that the internal geometry affects the pressure drop, which is highest for the triangular MCHE and lowest for the circular MCHE. However, the microchannel flow temperature change was relatively similar for all microchannels. Results showed that for the same volume of the microchannel, the circular shape microchannel has a higher performance index value than the triangular and square shapes. This study …

Existing data collected by the Texas Education Agency's Exit Survey by preservice teachers completing an educator preparation program was used to conduct a quantitative study. Data was imported into SPSS to conduct statistical analysis. The findings are discussed and recommendations for future research are provided to inform future development of technology integration in educator preparation programs.

The relationship between Erasmus of Rotterdam and the religious movement called the Devotio Moderna, especially the latter's relevance to Erasmian piety, has been a somewhat contentious historiographical issue. This thesis examines that relationship, and asserts that the Devotio Moderna was a crucial formative aspect of Erasmus' religiosity. However, its relevance ought not be overstated, due to the humanist's significant developments away from his spiritual forerunners.

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

One of the famous Russian composers and a pianist himself, Sergei Prokofiev (1891–1953) composed a vast quantity of piano music. His nine piano sonatas represent well how he projected his musical individuality and the principles that he addressed in his autobiography: classical line, modern trend, toccata line, lyrical line, and grotesque line. However, even though Prokofiev's piano sonatas are considered one of the important collections in the piano repertoire, not all of them have gained popularity and only a few tend to be frequently performed by pianists today. For this reason, this dissertation focuses on one of his less-performed piano sonatas, No. 4 in C minor, Op. 29. The pianists György Sándor and Boris Berman were chosen as specialists in Prokofiev's piano works, and their performance editions and recordings are analyzed and compared as main references. This study provides analysis and a performance guide to this piano sonata. This guide discusses pedaling, fingering, phrasing, touch, voicing, tempo suggestion, articulation, hand distribution, and expression.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental toxicants found in anthropogenic mixtures such as crude oil, air pollution, vehicle exhaust, and in some natural combustion reactions. Single PAHs such as benzo[a]pyrene (BaP) also impact fish behavior when animals are exposed in early life stages and for short periods of time. Aquatic animals such as fish may encounter BaP through road runoff and oil spills, but few studies have examined the impact of aqueous exposure on adult fish, and fewer have examined the resulting fitness-relevant behavioral consequences of BaP and PAH mixtures and their long-term persistence. This dissertation targets this gap in the literature by examining how aqueous exposure to BaP influences anxiety-like behavior, learning, and memory in adult zebrafish, and how parental exposure to the PAH mixture, crude oil, combined with hypoxia affects social and exploratory behavior in unexposed larval zebrafish. We found that learning and memory were not affected by 24 hour exposure to BaP, that anxiety-like behavior was minimally affected, and that locomotor parameters such as distance moved and times spent in darting and immobile states were significantly altered by exposure to BaP. Additionally, we found that parental exposure to crude oil and hypoxia decreased larval velocity. Additionally, …

Although the Dimensions of the Learning Organization Questionnaire (DLOQ) has been widely accepted by the HRD community, it has not been tested in a startup context for reliability. The purpose of the current study is to explore if the DLOQ is a reliable instrument for startups to help them be more successful. The current study seeks to address some of the questions, which have been posed by previous researchers. The study utilizes a mixed-method design applying Cronbach alpha values to check the reliability of the instrument in a startup learning environment, with more than 600 participants and 42 startup businesses at a university in the Mountain West. The study uses objective financial measures for startup firms to explore the correlation between the seven dimensions of the DLOQ and startup companies at the university. Cronbach alphas for the instrument measured at the .80 level or higher. Four of the dimensions were found to be statistically significant resulting in a model that accounted for 30% of the variance in predicted Operating Income (p<.004) and 29% of the variances in predicted Net Income (p<.003). The study also uses qualitative analysis to explore what activities relate to the seven dimensions of the DLOQ, and …

Manually grading essays and providing comprehensive feedback pose significant challenges for writing instructors, requiring subjective assessments of various writing elements. Automated essay scoring (AES) systems have emerged as a potential solution, offering improved grading consistency and time efficiency, along with insightful analytics. However, the use of AES in English as a Second Language (ESL) remains rare. This dissertation aims to explore the implementation of AES in ESL education to enhance teaching and learning. The dissertation presents a study involving ESL teachers who learned to use a specific AES system called LightSide, a free and open text mining tool, to enhance writing instruction. The study involved observations, interviews, and a workshop where teachers learned to build their own AES using LightSide. The study aimed to address questions related to teacher interest in using AES, challenges faced by teachers, and the influence of the workshop on teachers' perceptions of AES. By exploring the use of AES in ESL education, this research provides valuable insights to inform the integration of technology and enhance the teaching and learning of writing skills for English language learners.

The age-cutoff regression discontinuity design (RDD) has emerged as one of the most rigorous quasi-experimental approaches to determining program effects of prekindergarten on literacy and numeracy outcomes for children at kindergarten entry. However, few pre-K meta-analyses have focused attention on validity threats. The current random-effects meta-regression tests the moderating effects of prominent threats to validity, selection bias and sensitivity, on impact estimates generated from age-cutoff regression discontinuity studies from large-scale programs. Results from averaging dependent standardized mean difference effects suggested small positive moderating effects of total attrition and robust 3-month bandwidths on reading effects, but not on math. However, these results were not statistically significant. In contrast, results generated from robust variance estimation yielded a small statistically significant association between total attrition and math effects. These mixed results may warrant further research on prekindergarten evaluation methodology, evaluation estimation methods, and the totality of evidence used to inform policy.

In both Mexico and the U.S., abortion rights protests have been taking place in recent years, but while Mexico is moving forward with the legalization of abortion, the U.S. is going in the opposite direction with the overturning of Roe v. Wade. Through framing, journalists select salient information, shaping audiences' understandings of social movements. The protest paradigm suggests that due to journalistic norms and routines, journalists tend to focus on disruptive acts, which can stigmatize the protest. Additionally, scholars have stated that men and women photojournalists have different approaches to covering certain topics. This cross-national research combined a content analysis of photographs in U.S. and Mexican media with in-depth interviews with photojournalists to determine if photojournalists in each country are reproducing the protest paradigm and if there are gendered differences in how they photograph abortion rights protests. The results revealed that women and men photograph differently, with women capturing more intimate photos; however, photojournalists' gendered experiences are also influenced by how protesters perceive them. Furthermore, the study suggests that photojournalists from both countries are questioning objectivity and are attempting to move away from the protest paradigm. This research provides valuable insights into visual framing theory, protest news coverage, and gendered …

On April 16, 2014 the Sewol Ferry became one of the worst maritime disasters in South Korea with the loss of 304 passenger, the majority being high school students. South Korea is a collectivist culture, structured as a hierarchical system that teaches their students and children to always respect, listen, and trust authority figures especially in dangerous situations. This study explores how collectivist cultural elements impacted the response of the Sewol Ferry. By examining the timeline of the disaster through interviews, documentaries, news articles and media; this thesis offers insight into what happened that day by providing perspectives from the rescue crew, government officials, survivors, volunteers, and family members of those who died. The analysis showed that in collectivist culture, children and students are taught to trust and listen to authority figures when in dangerous situations, however because of the Sewol disasters, the culture of adhering to the hierarchical systems started to collapse. Students who survived stated that they no longer can trust and respect adults after the incident along with family members of the students who passed away and the public. Also, the government withheld information and failed to protect the children aboard the ferry, because they didn't want …
