Renewable power systems are becoming more affordable and provide better options than fossil-fuel generation, for not only the environment, but a benefit of a reduced cost of operation. Methods to optimize charging batteries from renewable technologies is an important subject for off-grid and micro-grids, and is becoming more relevant for larger installations. Overcharging or undercharging the battery can result in failure and reduction of battery life. The Arduino hybrid MPPT controller takes the advantage of solar and wind energy sources by controlling two systems simultaneously. The ability to manage two systems with one controller is better for an overall production of energy, cost, and manageability, at a minor expense of efficiency. The hybrid MPPT uses two synchronous buck DC-DC converters to control both wind and solar. The hybrid MPPT performed at a maximum of 93.6% efficiency, while the individual controller operated at a maximum 97.1% efficiency when working on the bench test. When designing the controller to manage power production from a larger generator, the inductor size was too large due to the frequency provided by the Arduino. A larger inductor means less allowable current to flow before the inductor becomes over saturated, reducing the efficiency of the controller. Utilizing …

Keep Denton Beautiful (KDB) is inspired by Keep America Beautiful's model of community engagement to create a clean, beautiful, and vibrant city. The community mural initiative, Artscapes, aims to enliven public spaces, abate graffiti, and inspire community members to keep Denton, Texas, clean and beautiful. The goals of this research project are to understand the impact of Artscapes initiative, community perceptions of public art, and find ways KDB can better align future mural projects with the needs and desires of community members. By talking to artists that have worked with KDB, members of the mural art committee, and community members from the neighborhoods that have existing murals, this research provides input from these three populations to continue creating public art for the Denton community. I discuss the context of my work through Lefebvre's concept of "Right to the City," Rafael Schacter's opposition between sanctioned and non-sanctioned murals, Bourdieu's concept of symbolic and social capital, and David Harvey's work on neoliberalism and the entrepreneurial city.

This dissertation presents a categorization of existing methodologies of upper register development for euphoniumists with evaluation of effectiveness and current use of these methodologies. The purpose of this study is to provide euphonium musicians as well as educators with essential references and guides to applicable methods for developing the upper register more effectively with greater efficacy. The assessments of current methodologies include three steps: categorization, summarization, and evaluation. To support the significance why it could be more beneficial than the methodology alone, the dissertation will include the examination of the aspect of biomechanics and ergonomics, suggestions, and discussion of particular issues of the upper register.

The purpose of this study was to examine the role of attachment processes and coping strategies in the development of psychiatric symptoms among military veterans and active duty personnel. Data were obtained from 268 male and female military veterans and active duty personnel. A path analysis was conducted to estimate the relationships between attachment processes, coping strategies, and psychiatric symptoms. Findings demonstrated that greater levels of attachment anxiety were related to increased levels of avoidant coping and psychiatric symptoms, while higher levels of attachment avoidance were related to avoidant coping and PTSD symptoms, as well as decreased levels of problem-focused coping. Alcohol use was associated with psychiatric symptoms. Avoidant coping, but not problem-focused coping, was associated with psychiatric symptoms and partially mediated the relationship between anxious attachment and psychiatric symptoms. Avoidant coping also fully or partially mediated the relationships of avoidant attachment to depression and PTSD symptoms. The findings of this study increase our knowledge of mechanisms that contribute to psychiatric symptoms among military populations, which in turn can guide treatment planning and interventions.

This study analyzes senior women faculty's discourses about personal and professional experiences they believe contributed to their advancement in academic careers in science, technology, engineering, and mathematics (STEM). The purpose of the study is to understand factors that activate women's success in STEM disciplines where women's representation has not yet attained critical mass. A poststructuralist emphasis on complexity and changing nature of power relations offers a framework that illuminates the ways in which elite women navigate social inequalities, hierarchies of power, and non-democratic practices. Feminist poststructural discourse analysis (FPDA) methods allow analysis of women's talk about their experiences in order to understand the women's complex, shifting positions. Eight female tenured full professors of STEM at research-focused universities in the United States participated in the study. Data sources were in-depth semi-structured interviews, a demographic survey, and curricula vitae. Findings will help shape programs and policies aimed at increasing female representation and promoting achievement at senior levels in academic STEM fields.

The Texas Constitution of 1876 set aside three million acres of Texas public land in exchange for construction of the monumental red granite Capitol that continues to house Texas state government today. The Capitol project and the land went to an Illinois syndicate led by men influential in business and politics. Austin's statehouse is a recognizable symbol of Texas around the world. So too, the massive Panhandle tract given in exchange -- what became the "fabulous" XIT Ranch -- has come to, for many, symbolize Texas and its role in the nineteenth century cattle boom. After finding sales prospects for the land, known as the Capitol Reservation, weak at the time, backed by British capital, the Illinois group, often called the Capitol Syndicate, turned their efforts to cattle ranching to satisfy investors until demand for the land increased. The operation included a satellite ranch in Montana to which two-year-old steers from Texas were sent for fattening, often "over the trail" on a route increasingly blocked by people and settlement. Rather than a study focused on ranching operations on the ground -- the roundups, the cattle drives, the cowboys -- this instead uncovers the business and political side of the Syndicate's …

The shortage of bilingual counselors is one barrier to young Latina/o children receiving mental health services. Child-centered play therapy (CCPT) is a developmentally responsive intervention based on the premise that play is children's natural means of communication across cultures. This randomized controlled study examined the effects of CCPT with young Spanish-speaking Latina/o children exhibiting clinical levels of school behavior problems. Participants were 57 pre-K to kindergarten Latina/o children (72% male; mean age = 4.0) randomly assigned to three treatment groups: CCPT with Spanish-speaking, bilingual counselors; CCPT with English-speaking, monolingual counselors; or active control (bilingual mentoring). Monolingual counselors participated in cultural competency training and supervision with bilingual counselors and supervisors. According to independent observers and teachers blinded to children's group assignment, both the bilingual CCPT group and the monolingual CCPT group demonstrated moderate treatment effects over bilingual mentoring, yet between-group differences were not statistically significant. Analysis of within-group change over time indicated that children in both CCPT interventions demonstrated statistically significant improvement, while the mentoring group did not. The percentage of children in each treatment group who improved from clinical to normal behavioral functioning suggests the clinical significance of the findings: 80% bilingual CCPT, 70% monolingual CCPT, 15% bilingual mentoring. Overall, …

Child centered play therapy (CCPT) is a therapeutic intervention that provides the environment for children to work through and heal from difficult experiences through expression of play and therapeutic relationship. It has been demonstrated effective with multiple types of disruptive behaviors. I conducted single-case research to explore CCPT's influence on children who had four or more adverse childhood experiences (ACEs) and provided analysis of data collected from one assessment administered weekly and one assessment at pre-, mid-, and post-intervention: the Strength and Difficulties Questionnaire and the Trauma Symptoms Checklist for Young Children. The two participants (one 8-year-old White American male and one 9-year-old White American female) demonstrated significant improvement in total difficulties and prosocial behaviors. The study revealed potential therapeutic benefits for utilizing CCPT with children who had four or more ACEs. Encompassed in discussion of study results are implications for practice, suggestions for future research, and limitations.

Education in Saudi Arabia, including the education of children with special needs, is developing rapidly. However, children with emotional and behavioral disorders are neither consistently identified nor adequately served in Saudi Arabia although they are recognized as a distinct category of children who require special education services. The goal of this study was to examine the prevalence of emotional and behavioral disorders among children in Saudi Arabia to assess the need for intervention services to help those children reach their potential. The current research identified the types of behaviors that are most evident in the study sample. Also, the relationship between demographics and emotional and behavioral disorders is studied to identify possible predictors of disruptive forms of behavior. Parents of children aged 4-17 years in Saudi Arabia were surveyed using the Strengths and Difficulties Questionnaire. The findings of the study suggest that children with emotional and behavioral disorders in Saudi Arabia may account for 20% of the population of children between the ages of 4 and 17. The findings also revealed that over 20% of children in Saudi Arabia have difficulties in peer relationship and lack the necessary prosocial behaviors. The parent reporting, child gender, child education type, the geographical …

The traditional narrative of political party development in the United States of America during the latter half of the 1790s ascribes the decline in popularity of the Federalist Party in the Election of 1800 to that party's passage of controversial legislation, specifically the Sedition Act of 1798, prior to the election. Between the passage of the Sedition Act and the Election of 1800, however, the midterm elections of 1798-1799 transpired and resulted in a significant increase in Federalist popularity in four states – North Carolina, South Carolina, Georgia, and Virginia. This study seeks to ascertain why these four states increased their support for the Federalist Party in 1798-1799, despite the passage of the Sedition Act by the Federalist Party. By examining newspapers and election results, this study analyzes the reaction of these four states to the passage of the Sedition Act and finds that generally, these states did not react strongly against the Sedition Act in the immediate aftermath of its passage. Instead, all four states urged national unity and emphasized the need to support the national government because the United States faced the threat of war with France. This study employs a state-by-state formula to determine each state's individual …

Sexual trauma within the military is a widespread issue, and rape myth acceptance has been shown to contribute to its prevalence. Given that the military culture has been shown to lend itself to hypermasculinity and traditional gender role adherence, both of which facilitate aggression toward women, this effect warrants investigation within a military sample. The present study replicated and expanded upon Aosved and Long's (2006) study examining 85 veteran and active duty military members' responses on the Illinois Rape Myth Acceptance Scale, Attitudes Toward Women Scale (short form), Neosexism Scale, Male Role Norms Inventory (short form), Modern and Old Fashioned Racism Scale, Modern Homophobia Scale, a modified version of the Economic Belief Scale, Fraboni Scale of Ageism, Religious Intolerance Scale, and the Marlowe–Crowne Social Desirability Scale (short form). Findings provide support for the co-occurrence of rape myth acceptance with intolerant attitudes, including sexism, hypermasculine gender role ideology, racism, sexual prejudice, classism, ageism, and religious intolerance, both individually and collectively. These results provide insight into the functioning of intolerant attitudes within a military sample, and provide important insight for future research addressing the association between rape myth acceptance and rape proclivity and the perpetration of military sexual assault.

The purpose of this study was to explore the extent to which alternative schools add value to the college readiness of their students, as well as to measure the capacity of alternative school students to successfully complete dual credit courses while enrolled at the alternative school. This mixed methods study utilized an exploratory approach with a descriptive research design to explore the extent to which alternative schools produce college-ready students. The Texas Success Initiative Assessment was used to measure participants' academic readiness levels in mathematics, reading, and writing. Additionally, participants had the opportunity to provide their own perspectives on their college readiness levels through a student survey and semi-structured face-to-face interview. The results of this study reveal that the college readiness levels of alternative high school students varied across academic areas. Of the tested participants, 41.1% were college ready in reading, 52.1% in writing, and 16.7% in mathematics. Additionally, the findings reveal that dual credit course participation was not a viable option because of course prerequisites and the amount of time needed to complete dual credit courses. Results of this study expand on the literature to provide a better understanding of the effectiveness of alternative school programs, the college readiness …

As the world becomes more connected, issues surrounding sustainable development are coming to the fore of global discussions. This is exemplified in strategies such as the United Nation's Sustainable Development Goals (SDGs), released in 2015, which created a framework for global development that defines specific goals for issues like poverty, climate change, and social justice. To complement the analysis that went into defining the SDGs, capital allocations around the world are becoming more impact focused so that the paradigm of development is shifting from donations to impact investments. The push for impact, however, has led to a homogenization of global challenges like reproductive health and poverty. This, in turn, has led to a standardization of information resulting in agencies designing interventions based on data and information that is misguided because of incorrect assumptions about a specific context. This paper explores how the decision-making mechanisms of global development agencies and investors could apply more anthropological processes to mitigate negative impact. As the development sector becomes more and more standardized, anthropologists can act as translators between affected communities and the institutions deciding how best to help them.

A study of Asian clam (Corbicula fluminea Müller) colonization in relation to changes in aquatic vegetation community as a result of management of Hydrilla verticillata (L. f.) Royle with grass carp was conducted at the Lewisville Aquatic Ecosystem Research Facility (LAERF), Lewisville, TX, from April 2015 through October 2016. Percent vegetation cover, C. fluminea abundance and water quality metrics (pH, turbidity, conductivity, DO, calcium, chlorophyll a) from 16 experimental subjects were analyzed. Treatments included four replicated grass carp stocking densities; 1-control with no fish stocked (n = 4), 2-low density of 40-43 fish per vegetated ha (n = 4), 3-medium density of 72-81 fish per vegetated ha (n = 4) and 4-high density of 110-129 fish per vegetated ha (n = 4). Data analysis showed statistical significance in the relation of C. fluminea abundance to percent vegetation cover (multiple linear regression, r2 = 0.820), grass carp stocking densities (two-way analysis of variance, p = <0.001) and chlorophyll a (multiple linear regression, r2 = 0.339). Findings of this research indicate the possibility that management of hydrilla had enabled establishment of secondary invasive species.

The objective of this study is to examine core-shell type plasmonic metamaterials aimed at the development of materials with unique electromagnetic properties. The building blocks of metamaterials under study consist of gold as a metal component, and silica and precipitated calcium carbonate (PCC) as the dielectric media. The results of this study demonstrate important applications of the core-shells including scattering suppression, airborne obscurants made of fractal gold shells, photomodification of the fractal structure providing windows of transparency, and plasmonics core-shell with a gain shell as an active device. Plasmonic resonances of the metallic shells depend on their nanostructure and geometry of the core, which can be optimized for the broadband extinction. Significant extinction from the visible to mid-infrared makes fractal shells very attractive as bandpass filters and aerosolized obscurants. In contrast to the planar fractal films, where the absorption and reflection equally contribute to the extinction, the shells' extinction is caused mainly by the absorption. This work shows that the Mie scattering resonance of a silica core with 780 nm diameter at 560 nm is suppressed by 75% and only partially substituted by the absorption in the shell so that the total transmission is noticeably increased. Effective medium theory supports …

In this dissertation, I examine the complex role that the body played in early modern constructions of judgment. Moving away from an overreliance on anti-theatrical texts as the authority on the body in Shakespeare's plays, my project intervenes in the field Shakespearean studies by widening the lens through which scholars view the body's role in the early modern theater. Through readings of four plays—Richard II, Hamlet, King Lear, and The Winter's Tale—I demonstrate that Shakespeare uses a wide range of ideas about the human body from religious, philosophical, medical, and cultural spheres of thought to challenge Puritan accusations that the public theater audience is incapable of rational judgment. The first chapter outlines the parameters of the project. In Chapter 2, I argue that Richard II draws parallels between the theatrical community and the community created through the sacramental experiences of baptism and communion to show that bodies play a crucial role in establishing common experience and providing an avenue for judgment. In Chapter 3, I argue that Shakespeare establishes correspondences between bodily and social collaboration to show how both are needed for the memory-making project of the theater. In the next chapter, I show how Shakespeare appropriates what early moderns …

This study explored participants' experiences of being interviewed with the Adult Attachment Interview as a means of supporting counselor self-awareness and fostering effective counselor-client working alliances. A sample of first-year counselor education doctoral students (n = 7) completed an AAI interview and feedback session. Participants completed five reflective journals over three weeks and explored their experiences in individual, semi-structured interviews. Data were analyzed according to interpretative phenomenological analysis protocol. Four superordinate themes emerged from the analysis: (a) reactions to the AAI interview process, (b) process with AAI feedback, (c) AAI and intrapersonal process, and (d) AAI and interpersonal process. Additionally, there were eight subordinate themes: (a) surprised by AAI interview process, (b) interview process sparked reflection, (c) initial reaction to AAI feedback, (d) evolving process of integrating AAI feedback, (e) AAI process increased awareness, (f) increased self-awareness increased self-efficacy, (g) awareness from AAI process prompted relational shifts, (h) impact of AAI on clinical work, (i) importance of relationships, (j) importance of self-awareness, and (k) mutual influence of personal and professional. Findings in this study suggest that the AAI is an effective tool in supporting counselor self-awareness regarding attachment strategies. Additionally, findings suggest multiple personal and professional benefits, such as increased …

A nuclear microprobe, typically consisting of 2 - 4 quadrupole magnetic lenses and apertures serving as objective and a collimating divergence slits, focuses MeV ions to approximately 1 x 1 μm for modification and analysis of materials. Although far less utilized, electrostatic quadrupole fields similarly afford strong focusing of ions and have the added benefit of doing so independent of ion mass. Instead, electrostatic quadrupole focusing exhibits energy dependence on focusing ions. A heavy ion microprobe could extend the spatial resolution of conventional microprobe techniques to masses untenable by quadrupole magnetic fields. An electrostatic quadrupole doublet focusing system has been designed and constructed using several non-conventional methods and materials for a wide range of microprobe applications. The system was modeled using the software package "Propagate Rays and Aberrations by Matrices" which quantifies system specific parameters such as demagnification and intrinsic aberrations. Direct experimental verification was obtained for several of the parameters associated with the system. Details of the project and with specific applications of the system are presented.

This dissertation is about economic resilience of local governments to natural disasters. Specifically, the dissertation investigates resilience on regional level. Moreover, the dissertation also investigates growth in the green job sector in local governments. The findings indicate that local governments working with each other helps green job creation. In addition, the dissertation finds that green jobs, following disasters, experience three percent growth. This dissertation is important because it investigates the relationship between climate- related disasters and green jobs, which is an area that is under-investigated.

This exploratory and descriptive study provides an increased understanding of the topics being explored in both published research and industry reporting in the field of educational technology. Although literature in the field is plentiful, the task of synthesizing the information for practical use is a massive undertaking. Latent semantic analysis was used to review journal abstracts from ten highly respected journals and the New Media Consortium Horizon Reports to identify trends within the publications. As part of the analysis, 25 topics and technologies were identified in the combined corpus of academic journals and Horizon Reports. The journals tended to focus on pedagogical issues whereas the Horizon Reports tended to focus on technological aspects in education. In addition to differences between publication types, trends over time are also described. Findings may assist researchers, practitioners, administrators, and policy makers with decision-making in their respective educational areas.

Older adopted children and their families often express high need for support for attachment and trauma related concerns. Post-adoption mental health intervention focused on enhancing the parent-child relationship among adoptive parents and adoptees is essential for fostering placement permanency among these families. This single group pilot study explored the effect of Child-Parent Relationship Therapy (CPRT) for adoptive parents of preadolescents who reported attachment related concerns, stress in the parent-child relationship, and child behavior problems. Participants were 11 adoptive parents ages 25 to 64 (55% male; 91% couples; 100% married; 56% European American, 27% Asian, 9% Hispanic, and 9% Black American) with adoptees between the ages of 8 to 14 (56% male; 56% Hispanic, 33% European American, and 11% Black American). All child participants were adopted out of foster care. Data was collected at baseline, pretest, midtest, and posttest. Results from non-parametric Friedman test of differences across 4 points of measure indicated that CPRT demonstrated statistically significant improvement for the 3 outcome variables: parental empathy, child behavior, and parent child relationship stress. Specifically, results indicated that prior to receiving CPRT (baseline to pretest), parents demonstrated no change or worsening in functioning across all variables, whereas during the intervention phase findings showed …

This randomized, controlled study examined the effectiveness of two mentoring programs, child mentor relationship training (CMRT) and peer assistance and leadership (PAL®), on high school mentor empathic behaviors and child mentee behavior problems. Participants were 60 young, at-risk students (61.7% male; 38.3% Hispanic/Latino/a, 31.7% Caucasian, 21.7% African American, 8.3% biracial) and 30 high school students (53.3% male; 66.7% Caucasian, 26.7% Hispanic/Latino/a, 0.03% African American, 0.03% Asian). Mentors and mentees were randomly assigned to CMRT or PAL®, which was treatment as usual in the participating school district. Results from 2 (group) by 2 (time) repeated measures ANOVAs indicated compared to the PAL® treatment group over time, mentors in the CMRT group demonstrated statistically significant improvement in empathic behaviors with a large treatment effect, as rated by independent observers. Analysis revealed a moderate treatment effect with CMRT group mentee behavior problems, but the difference was not statistically significant between treatment groups over time. Further analysis revealed the CMRT group demonstrated statistically significant reductions in behavior problems from pre- to post-test with a very large treatment effect. Overall, findings support CMRT as a promising school-based intervention for at-risk young children that potentially increases school counselor efficiency.
