Extant research suggests that some of the potential harms to social bonds during the incarceration experience may be mitigated by visitation. In particular, previous studies have found visitation from family and friends to be significantly related to decreased recidivism rates among adult prisoners. Little is known about the impact of visitation on recidivism among juvenile populations, which this study sought to address. Utilizing data from the Pathways to Desistance study, a series of negative binomial regressions were carried out to observe the potential relationship between maternal and paternal caregiver visitation and post-release self-reported offending among serious juvenile offenders. No significant relationship was found between caregiver visitation and recidivism, contrary to expected results. This held true for both maternal and paternal caregiver visitation as well as both dichotomous and visit count measures. Further research is needed to determine why visitation studies among adult populations do not appear to generalize to juveniles. Visitation quality and nature of the relationship with caregivers should be observed in future studies.

Fusarium head blight (FHB) is an important disease of small grain cereals including wheat that affects grain quality and yield. The fungus Fusarium graminearum (Fg) is the major agent of this disease. Lack of natural resistance has limited ability to control wheat losses to this disease. Developing new approaches is critical for increasing host plant resistance to this fungus. This work has identified four processes that can be targeted for enhancing host plant resistance to FHB. The first involves targeting the pattern-triggered immunity mechanism to promote host plant resistance. Two other approaches involved reducing activity of susceptibility factors in the host to enhance plant resistance. The susceptibility factors targeted include accumulation of the phytohormone jasmonic acid and the 9-lipoxygenase pathway that oxidizes fatty acids. Besides suppressing host defenses against Fg, jasmonic acid also directly acts on the fungus to promote fungal growth. 9- lipoxygenases similarly suppress host defenses to promote fungal pathogenicity. Another approach that was developed involved having the plant express double stranded RNA to target fungal virulence genes for silencing. This host-induced gene silencing approach was employed to target two fungal virulence genes, the lipase encoding FGL1 and salicylate hydroxylase encoding FgNahG, which the fungus secretes into the …

Over the past 25 years, research on the effectiveness of new technologies in teaching has been constantly evolving as teachers try to keep up with educational trends. With the current evolution of technology, it is important to find out how students feel about the use of technologies in both the classroom setting and the non-traditional learning environment. The objective of this project is to determine which applications the students of French 1010 (first semester of college-level French) at the University of North Texas use for language learning to supplement and reinforce the concepts learned in class. Two questions guided this project: (1) what are the new technologies that students in French 1010 use? and (2) if UNT were to implement hybrid classes, would students be interested in taking them? In order to answer these questions, a survey was distributed to 184 students of French 1010 at UNT during the fall 2019 semester. From these surveys, 100 were selected for analysis in the present study, and three students were interviewed as a way to collect additional data. The results of the survey showed that Duolingo was the most used application for language learning purposes, while the interviews showed that the students …

Building on Fredric Jameson's critical theory, this dissertation examines how the aesthetics of cognitive mapping were used to uncover overlooked political, economic, social and cultural dimensions behind my artistic engagement with Islamic patterns. Using a critically informed variant of arts-based research (ABR), I explored the complexity of the interconnected economic, social, political and aesthetic realities informing my positionality as a Muslim Saudi female artist/research completing her dissertation in a Western country. Particularly, my work revealed how certain global forces (including capitalist relations between Saudi Arabia and the USA, as well as global postmodern cultural influences) shape the processes of appropriation and re-signification of patterning appropriated from Islamic aesthetics. This research culminated in a body of artwork for a solo exhibition at Paul Voertman's Gallery at the College of Visual Arts and Design at the University of North Texas located in Denton, Texas. I conclude the study with recommendations for a regional ABR to be developed by educators for the Middle East and North Africa (MENA) region. The study also suggests that this model of cognitive mapping as a critical art making methodology would be a great pedagogical tool for museums and art education curriculum to implement in Saudi Arabia.

A comparative analysis of the musical transcriptions of Dorothy Ashby with those of her predecessors proves that Ashby was a uniquely powerful and innovative influence on the genre of jazz harp. This dissertation begins with a summative biography of Ashby, following her education in both jazz and classical music through to her career highlights as a performer, arranger and composer. An analysis of Ashby's recordings reveals the development of her groundbreaking musical style throughout her life. This paper also examines Ashby's social activism through musical theatre, especially with regards to combating racism. Next, a brief biography of jazz harp forerunners Casper Reardon and Adele Girard precedes a comparative analysis of Reardon's "Aint' Misbehavin" with Ashby's "Soft Winds" and a comparative analysis of Girard's "Harp Boogie" with Ashby's "Blues for Mr. K." Finally, myriad examples of current musicians covering and sampling her work confirm the paramount and lasting influence of Dorothy Ashby's music.

Since most historical composers of Western art music were European Christians (or resided in areas that were primarily populated by Christians), a vast majority of the sacred choral-orchestral repertoire is based on major figures and themes from the most prominent denominations, including Catholicism, Lutheranism, and Anglicanism. As a corollary this is also the case for analytical, pedagogical, and exegetical literature related to the topic. However, in the late nineteenth century some composers began to look to other faith traditions for inspiration, which resulted in compositions based on texts that are less-familiar to Western audience members and performers. Despite the fact that many of these pieces are innovative and well-written, few, if any, have entered the standard repertoire. Because of this they are under-represented in both performance and extant music literature. The purpose of this study is to examine three compositions from this marginalized category in order to produce a guide that provides salient information on the religious/cultural background and musical aspects of each work. This guide will serve as a resource for conductors to facilitate an understanding of and connection with the text, allow informed programming decisions, and promote approaches that are appropriate and respectful to the religious source material. …

An event is something that happens at a time and location. Events include major life events such as graduating college or getting married, and also simple day-to-day activities such as commuting to work or eating lunch. Most work on event extraction detects events and the entities involved in events. For example, cooking events will usually involve a cook, some utensils and appliances, and a final product. In this work, we target the task of determining whether events result in their expected outcomes. Specifically, we target cooking and baking events, and characterize event outcomes into two categories. First, we distinguish whether something edible resulted from the event. Second, if something edible resulted, we distinguish between perfect, partial and alternative outcomes. The main contributions of this thesis are a corpus of 4,000 tweets annotated with event outcome information and experimental results showing that the task can be automated. The corpus includes tweets that have only text as well as tweets that have text and an image.

Ways of understanding, living, and communicating with non-human species, and more specifically endangered species, have been thought of dualistically and hierarchically in Western cultures. This type of thinking is harmful when examining environmental issues that involve more than just humans, which is arguably all environmental issues. By enforcing a nature/culture dichotomy, humans are seen as separate from nature and therefore they can ethically excuse themselves from dealing with environmental issues that happen "out there" in nature. This thesis explores two manifestations of this nature/culture separation as it continues to threaten wild orca populations in Puget Sound. The first is because of an anthropocentric culture and the second is because of the capitalist socio-economic system. The anthropocentric part of this type of thinking raises humans up on a pedestal, above all non-human species. It gives humans the excuse to only care about issues that affect them directly. The capitalistic part of this type of thinking enforces human's exploitation and commodification of nature. I argue that anthropocentrism and capitalism together create a human/nature relationship that harms nature and benefits humans. This relationship is illustrated by a small population of orcas, called the Southern Resident Killer Whales (SRKW), off the coast of Washington …

The purpose of this exploratory study was to investigate the relationship between the digital divide and the Latino-White achievement gap in online education. Through an analysis of archival enrollment and academic performance data a comparison was conducted between online and face-to-face courses by ethnicity. Additionally, academic performance data was then compared to survey responses from online students on digital motivation, material access, internet skills, and internet usage. Findings and recommendations for future research are discussed and provided to continue the exploration of disparities of digital access and academic performance in an effort to inform decisions in higher education.

Students' self-determination (SD) can positively influence their ability to make choices in planning for their future. The current study is a preliminary validity study on the most recent 21-item version of Shogren and Wehmeyer's Self-Determination Inventory: Student Report (SDI-SR). The SDI-SR was administered to 316 students (ages 13-22) and results were examined with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results of the EFA on a 7-factor solution (TLI = 0.97; RMSEA = 0.04; SRMR = 0.02) aligned with the theoretical basis for the SDI:SR as well as results for the 7-factor CFA using simulated data (TLI = 0.913; RMSEA = 0.047; SRMR = 0.072 and CFI = 0.931); however, the CFA 7-factor solution results on the present study data were slightly lower than what is considered acceptable model fit (TLI = 0.883; RMSEA = 0.04; RMSR = 0.047). These results combined suggest that theory-based 7-factor solution does capture seven latent constructs in this data. A CFA was also conducted with a 5-factor structure based on factor loading from an EFA using the present research data resulting in a better model fit (TLI = 0.912; RMSEA = .075; SRMR = 0.046; and CFI = 0.940) as well as …

The Texas High Plains produces the most substantial amount of cotton in Texas. The region is a semi-arid area with limited precipitation, and it is, therefore, susceptible to climate change. Cotton production in the Texas High Plains is mostly dependent on irrigation to increase yield. The overall goal of this research was to study the interrelationships between climate change and cotton yield using correlation analysis and also to study how climate has changed in the region using trend analysis. A three-decade data (1987-2017) was analyzed to establish the relationship between climate change and cotton and also to determine how climate has changed in the area over the last 30 years. The research used precipitation and temperature data to assess climate change.The results of this research showed that annual mean temperature has lesser impacts on cotton yield, and the correlation between annual precipitation and cotton yield is insignificant. It also found out that high rates of temperature at the boll opening stage of cotton growth results in decreased cotton yield and that at the boll development and boll opening stages, precipitation is needed. Again, the research indicated that, on average, there had been a significant increase in temperature, but precipitation trends …

White paper providing general analysis and documentation of results collected by a Qualtrics survey to gather information about metadata assessment practices among digital libraries. It includes an overview of the responses and brief analysis, with some interpretation of trends.

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

Children acquire many skills through play. These range from fine and gross motor skills, social skills, problem-solving, to even creativity. Creativity or creative engagement is frequently a component in early preschool curricula. A pivotal repertoire to engage in behaviors deemed creative, such as art, storytelling, problem-solving, and the like, is the ability to vary one's responses regardless of the specific repertoire. Researchers have developed methods to produce response variability. However, notwithstanding the significant contributions from the literature for prompting response variability, it remains unclear how much variation in responding is socially appropriate. To fill this research gap, the purpose of this study is to characterize and understand the different ways preschool children commonly interact with the activities and materials present in a preschool classroom. In our study, we assessed children's repeat item interactions, novel item interactions, and time allocation across seven concurrently available activity centers. A multifarious pattern for item interactions emerged across children. Some children had restricted levels of novel item and center interactions, while other children had more varied novel item and center interactions. However, the variance in interactions was predominantly controlled by the center type. This study bolsters our understanding of variability and creativity within a school …

Myosin subfragment-2 (S2) is an intrinsically unstable coiled coil. This dissertation tests if the mechanical stability of myosin S2 would influence the availability of myosin S1 heads to actin thin filaments. The elevated instability in myosin S2 coiled coil could be one of the causes for hypercontractility in Familial Hypertrophic Cardiomyopathy (FHC). As hypothesized FHC mutations, namely E924K and E930del, in myosin S2 displayed an unstable myosin S2 coiled coil compared to wild type as measured by Fluorescence Resonant Energy Transfer (FRET) and gravitational force spectroscopy (GFS). To remedy this, anti-S2 peptides; the stabilizer and the destabilizer peptides by namesake were designed in our lab to increase and decrease the stability of myosin S2 coiled coil to influence the actomyosin interaction. Firstly, the effectiveness of anti-S2 peptides were tested on muscle myosin S2 peptides across MYH11 (smooth), MYH7 (cardiac), and MYH2 (skeletal) with GFS and FRET. The results demonstrated that the mechanical stability was increased by the stabilizer and decreased by the destabilizer across the cardiac and skeletal myosin S2 isoform but not for the smooth muscle isoform. The destabilizer peptide had dissociation binding constants of 9.97 × 10-1 μM to MYH7 isoform, 1.00 μM to MYH2 isoform, and no …

Two important developments are addressed by this dissertation. First, the Psychological Inventory of Criminal Thinking Styles-Simplified Version (PICTS-SV) was examined in relation to the original PICTS. Second, the vulnerability of the PICTS-SV to intentional risk minimization (RM) was tested. Two separate studies recruited a total of 150 offenders from a court-mandated residential substance use treatment facility. As expected, Study I established the PICTS-SV's good concurrent validity with the PICTS, especially at the broad composite scale level. For Study II, criminal thinking failed to show the anticipated convergence with HCR-20 risk classifications or forensic correlates. Potential explanations, including a restricted range of risk levels in this sample, are discussed. As a particular strength, the findings highlight that the PICTS-SV, in contrast to many risk measures, displays robust resistance to RM distortion, although revisions to its Df-r validity scale are warranted. These results overall demonstrate strong evidence of the PICTS-SV's utility for assessing a dynamic criminogenic need to inform effective interventions and accurate risk determinations.

In geometry we will consider n-dimensional generalizations of the Power of a Point Theorem and of Pascal's Hexagon Theorem. In generalizing the Power of a Point Theorem, we will consider collections of cones determined by the intersections of an (n-1)-sphere and a pair of hyperplanes. We will then use these constructions to produce an n-dimensional generalization of Pascal's Hexagon Theorem, a classical plane geometry result which states that "Given a hexagon inscribed in a conic section, the three pairs of continuations of opposite sides meet on a straight line." Our generalization of this theorem will consider a pair of n-simplices intersecting an (n-1)-sphere, and will conclude with the intersections of corresponding faces lying in a hyperplane. In graph theory we will explore the interaction between zero forcing and cut-sets. The color change rule which lies at the center of zero forcing says "Suppose that each of the vertices of a graph are colored either blue or white. If u is a blue vertex and v is its only white neighbor, then u can force v to change to blue." The concept of zero forcing was introduced by the AIM Minimum Rank - Special Graphs Work Group in 2007 as a …

The primary goal of the research project was to organize a community needs assessment, which culminated in a report attached in the appendix. Data from sixteen interviews with community leaders involved in mental health promotion throughout Dallas County, Texas was used as the foundation of the professional report. This data revealed several key barriers faced by those with mental illness in their ability to access mental health services in Dallas County. The information gathered prompted further exploration into the intersection between public transit and mental health. Transit became the focus of this work when it came up as simultaneously a barrier to care and mode of prevention in the majority of the interviews. Interestingly, Dallas County has public plans to address transit related disparities; however, their intervention pulls from strategies determined to be ineffectual among the poor and disenfranchised. In this work we explore community needs and the civic culture of Dallas with a specific focus on transportation.

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

Subject of information entity is one of the fundamental concepts in the field of information science. Subject of any document represents its intellectual potential -- 'aboutness' of the document. Traditionally, subject (along with title and author) is the one of three major ways to access information, so subject metadata plays a central role in this process and the role is constantly growing. Previous research concluded that the larger bibliographic database is, the richer subject vocabularies and classification schemes are needed to support information discovery. Further, a high proportion of information objects are unretrievable without subject headings in metadata records. This exploratory study provides the analysis of the subject metadata in MARC 21 bibliographic records created in 2020; and develops understanding of the level and patterns of 'aboutness' representation in the MARC 21 bibliographic records. Study also examines how these records apply the recent RDA and MARC21 guidelines and features intended to support functionality in a Linked Data environment. Methods of Social Network Analysis were applied along with content analysis, to answer research questions of this study. Suggestions for future research, implications for education, and practical recommendations for library metadata creation and management are discussed.

This dissertation investigates how W. A. Mozart applies the concept of key characteristics—the affective properties of each tonality—as discussed by three of his contemporaries, Johann Mattheson, C.F.D. Schubart and G.J. Vogler, to four soubrette and four prima donna characters from four of his late Italian operas: La Contessa and Susanna in Le nozze di Figaro; Donna Anna and Zerlina in Don Giovanni; Fiordiligi and Despina in Così fan tutte; Vitellia and Servilia in La clemenza di Tito. The analytical method of this dissertation provides a hermeneutical tool to search for meanings in Mozart's music. The application compares the libretto text and its corresponding tonal center with the description of key characteristics on a micro level, to reveal significant dramatic and practical implications from Mozart's key usage in his operas.

My research examines the three interrelated concepts of crisis; new imperialisms, spatial-temporal fix and accumulation by dispossession (ABD) stemming from the work of David Harvey as a way to understand the contested history of the Pakistan Railways. For the first thirty odd years after Pakistan's inception in 1947, the railways, a state-owned institution, was the primary mode of transport for the public, cargo, and workers. Alongside basic infrastructure, the railways had a vast network of hospitals, schools, workers' colonies and an array of physical infrastructure connected to production, operations and other aspects of the economy. The systematic ransack and decline of the Pakistan Railways reached its peak in 2010. Despite several attempts throughout the 1990s by successive democratic and military-led governments backed by the IMF/World Bank in 2015, it was announced that Pakistan railways would be revived under the banner of the 46 billion dollar China Pakistan Economic Corridor (CPEC) as part of the changing geopolitical context of growing regional connectivity and new Chinese imperialism. By examining the processes that underlie ABD, such as spatial-temporal fix, the following research shows that these processes not only reflect a shift of resources away from the public domain, but in Pakistan also entailed …

Mental health is an intrinsic capability that constitute an essential component of healthy aging. Mental health is constituted by positive constructs such as happiness and negative constructs (mental disorders) such as depression. As people grow older, they become more prone to developing mental disorders which are linked to poorer quality of life, increased disability, increased utilization and cost of health services, and higher rates of suicide. This dissertation involved three studies that focused on factors that predict change in mental disorders and happiness of older Americans over a period of five years. Two waves of publicly available national representative data from the National Social Life Health and Aging Project (NSHAP) collected in 2010 and 2015 were used. A total of 2210 older adults within the ages 62-90 years were used in the analyses. Mental health measures were CES-Depression scale, HADS anxiety scale, and self-rated happiness. Essay 1 aimed to identify the important aspects of older adults' interaction with their neighborhood that predict the presence of mental disorder and happiness. Essay 2 evaluated the psychosocial factors that predict change in mental disorder and happiness of older adults, whereas essay 3 investigated the multifactorial determinants of change in mental disorder and happiness …

The use of collection systems for magnetic sorbents such as Magnetic Activated Carbon are discussed in order to gauge their efficacy in marine environments. Two collectors were built and tested, one which utilized a radial orientation of magnets and another with axially placed magnets. The two systems underwent a series of test with differing linear velocities and angular velocities. From the results, the axial system outperformed its radial counterpart, being most effective with a relatively high concentration of discs placed in series. The medium concentration, however, proved increasingly effective with higher velocities, meaning an optimization concentration exists for this design. The radial system was tested with high and low concentrations of small and large magnets, respectively. The larger magnets, although providing less concentration points in the alternating array, proved more effective for the collection of MAC. From these tests several new innovations were suggested, including belt tensioners, add on mechanisms, and a hybridized design in order to fully optimize the collection of MAC.
