Although Latinos are the largest minority group in the country, research examining how different psychological and cultural variables affect Latino individuals' wellbeing is disproportionately developed and cross-cultural comparison studies are particularly scarce. To address these issues, this dissertation research examined cross-cultural adult attachment-social self-efficacy-psychosocial wellbeing conceptual mediational model while investigating the moderator effects of country membership and familismo on the proposed mediational model using a cross-cultural sample of Mexican and Mexican-American university students. A total of 595 participants, including 360 Mexican students from Mexico and 235 Mexican-American students from the United States completed the research questionnaires. Results indicated that social self-efficacy was a significant mediator for the effects of insecure attachment on life satisfaction and conflict resolution in both cultural groups and for the links between attachment insecurity and depressive symptoms in the Mexican-American group. Additionally, moderated mediation analyses showed that country membership was a significant moderator for the links between attachment avoidance and social self-efficacy when life satisfaction, conflict resolution style, and depressive symptoms were the dependent variables, as well as for the direct link between attachment anxiety and physical health symptoms. Familismo was also found to be a significant moderator for the direct effects of attachment anxiety on …

Individuals evidencing psychopathic personality traits have been shown to have problematic attachment to others. Moreover, research suggests that culture affects attachment style as well as the expression of various psychopathic traits using the four-factor model of psychopathy. However, the majority of this research has included only white college students, which is a limiting factor. The current study assessed the relations among attachment representations and psychopathic features across two independent samples (one adult & one adolescent) from different world regions (adults only), ethnicity (adolescents only), and gender. Using similar assessments of attachment and psychopathic traits for both samples, dismissing attachment was related to aspects of psychopathic traits in nearly all cultures and ethnicities sampled. In the world sample, secure attachment was found to positively relate to impulsive and parasitic lifestyle traits in all regions. Culture and gender were found to moderate several relations between specific attachment styles and psychopathic features. Overall, the patterns of data indicated that many of the differences found between groups may be rooted in individualistic versus collectivistic values, and were consistent with previous research assessing these constructs across diverse samples.

This qualitative case study examined the recruitment and hiring practices of an urban district. Participants in this study included five district-level, human resource staff members and six campus principals. Data collected and analyzed including audio recordings of semi-structured interviews of each participant and documents at the district and campus levels used during the recruitment and hiring processes. The findings suggested that there is evidence of the district's use of the fit theory and culturally relevant pedagogy, and there is potential value in uniting and using both theories to identify and hire culturally responsive teachers. Findings also suggested that some tenets of both theories overlap, and some were more evident and more valued in the district processes than others. Since urban schools tend to experience significant staffing challenges and require teachers who are more culturally responsive, this study has the potential to help district and campus leaders examine their current hiring practices and establish stronger connections to the fit theory and culturally relevant pedagogy tenets.

This multi-faceted research study examined the current approach of educational technology courses and how integrating modern learning technologies into curriculum effectively is addressed in pre-service education programs at U.S. universities. The primary goal was to explain the current trends in the reviewed pre-service programs in relation to how future educators are prepared by the universities to incorporate educational technology and use technology enhanced curriculum. This study was an exploratory, non-positivistic qualitative study that employed multi-strategy and survey research approaches in order to establish a baseline of the way that technology integration skills are being addressed in undergraduate pre-service educator programs today. Survey participants were educators within a public or private K-12 system in the U.S. The participants' level of education, university attended, educational technology experience, and technology perceptions were gathered from the survey's Likert-type and open-end questions. Current and historically statistics and data were collected for each university identified from the survey responses. Findings of this study revealed outcomes related to participants' education, perception of educational technology, and university educational technology course offerings and/or requirements for undergraduate pre-service educator programs. Results of this research study provide a solid foundation for future research in these areas within the field of education.

The large difference between processor CPU cycle time and memory access time, often referred to as the memory wall, severely limits the performance of streaming applications. Some data centers have shown servers being idle three out of four clocks. High performance instruction sequenced systems are not energy efficient. The execute stage of even simple pipeline processors only use 9% of the pipeline's total energy. A hybrid dataflow system within a memory module is shown to have 7.2 times the performance with 368 times better energy efficiency than an Intel Xeon server processor on the analyzed benchmarks. The dataflow implementation exploits the inherent parallelism and pipelining of the application to improve performance without the overhead functions of caching, instruction fetch, instruction decode, instruction scheduling, reorder buffers, and speculative execution used by high performance out-of-order processors. Coarse grain reconfigurable logic in an energy efficient silicon process provides flexibility to implement multiple algorithms in a low energy solution. Integrating the logic within a 3D stacked memory module provides lower latency and higher bandwidth access to memory while operating independently from the host system processor.

This study explores the demand and supply oriented factors that may contribute to the size of nonprofit organizations in the U.S. communities. This research tests demand theory, which indicated that nonprofit organizations grow more in communities where large service demand exists and when there is a service gap between community demand and government service supply. On the other hand, supply theories contend that nonprofit organizations are prevalent where a community carries the supply of human capital and financial resources and these supply of human and economic capital will mobilize nonprofit organizations to fulfill civic duties. For the scientific test of demand and supply theories, this study employs hierarchical linear model (HLM) and develops a longitudinal data set from multiple sources such as Department of Housing and Urban Development and National Charitable Center for Statistics, and Census. The proposed model analyzes how demand and supply indicators explain homeless serving nonprofit organizations size. The size of homeless service nonprofit was measured by three indicators: number of nonprofits, revenue of nonprofits and number of shelter beds. The findings of HLM analyses confirmed some of demand and supply factors that contribute homeless service nonprofit size. The communities with higher level of chronic homeless population …

Although early Venetian operas by composers such as Claudio Monteverdi and Francesco Cavalli offer today's listeners profound moments of emotion, the complex codes of meaning connecting emotion (or affect) with music in this repertoire are different from those of later seventeenth-century operatic repertoire. The specific textual and musical markers that librettists and composers used to indicate individual emotions in these operas were historically and culturally contingent, and many scholars thus consider them to be inaccessible to listeners today. This dissertation demonstrates a new analytical framework that is designed to identify the specific combinations of elements that communicate each lifelike emotion in this repertoire. Re-establishing the codes that govern the relationship between text, musical sound, and affect in this repertoire illuminates the nuanced emotional language of operas by composers such as Claudio Monteverdi, Francesco Cavalli, Antonio Cesti, and Francesco Lucio. The new analytical framework that underlies this study derives from analysis of seventeenth-century Venetian explanations and depictions of emotional processes, which reveal a basis in their society's underlying Aristotelian philosophy. Chapters III and IV examine extant documents from opera librettists, composers, audience members, and their associates to reveal how they understood emotions to work in the mind and body. These authors, …

The primary purpose of this study is to provide connections between a formal motivic analysis and the programmatic content of David Maslanka's three works for unaccompanied marimba: Variations on Lost Love (1977), My Lady White (1980), and A Solemn Music (2013). A comparison of the compositional process of each of these works is proposed through terms of Maslanka's use of depiction. Depiction is the action or result of representing through drawing, painting, or other art form, in this case, music. In each work for unaccompanied marimba, Maslanka uses this process of depiction in a unique way. The depictive mediums are categorized as evocative, representative, and introspective and these distinct approaches to depiction lead to three drastically different musical works. The different methods of depicting source materials are the distinguishing characteristics that separate these three works for solo marimba. This document includes a motivic analysis and comparisons of compositional devices used in these three works. A brief overview of Maslanka's life and works as well as a listing of all of his works that feature percussion instruments are also included.

In this dissertation, density functional theory calculations are performed to calculate the thermodynamic and electrochemical properties of metal coordinated frameworks for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Gibb's free energy, overpotential, charge transfer and ligands effect are evaluated. The charge transfer analysis shows the positive charges on the metal coordinated frameworks play an essential role in improving the electrochemical properties of the metal coordinated frameworks. Based on the calculations, design principles are introduced to rationally design and predict the electrochemical properties of metal coordinated frameworks as efficient catalysts for ORR and OER. An intrinsic descriptor is discovered for the first time, which can be used as a materials parameter for rational design of the metal coordinated frameworks for energy storage and conversion. The success of the design principles provides a better understanding of the mechanism behind ORR and OER and a screening approach for the best catalyst for energy storage and conversion.

For musicians of all kinds, practice is an essential component in establishing and refining their skills. How a musician learns the art of practicing, and at what point in their musical and cognitive development can vary drastically. The purpose of this research is to understand how two groups of musicians, undergraduate vocal performance majors and undergraduate piano performance majors, developed (or consequently failed to develop) their respective knowledge pertaining to effective practice prior to entering the university setting, and how their practice habits changed (or consequently failed to change) after beginning study with a university instructor. This is accomplished by comparing the practice habits of the two groups prior to entering the university setting, and, after gaining admission into the degree program. Findings are supplemented with recent research pertaining to the study of learning and various types of practice.

This research methodology isolates coding properties and identifies the probability of security vulnerabilities using machine learning and historical data. Several approaches characterize the effectiveness of detecting security-related bugs that manifest as vulnerabilities, but none utilize vulnerability patch information. The main contribution of this research is a framework to analyze LLVM Intermediate Representation Code and merging core source code representations using source code properties. This research is beneficial because it allows source programs to be transformed into a graphical form and users can extract specific code properties related to vulnerable functions. The result is an improved approach to detect, identify, and track software system vulnerabilities based on a performance evaluation. The methodology uses historical function level vulnerability information, unique feature extraction techniques, a novel code property graph, and learning algorithms to minimize the amount of end user domain knowledge necessary to detect vulnerabilities in applications. The analysis shows approximately 99% precision and recall to detect known vulnerabilities in the National Institute of Standards and Technology (NIST) Software Assurance Metrics and Tool Evaluation (SAMATE) project. Furthermore, 72% percent of the historical vulnerabilities in the OpenSSL testing environment were detected using a linear support vector classifier (SVC) model.

Max Reger was a prolific composer on the threshold of modernism. The style of his extensive musical output was polarizing among his contemporaries. A criticism of Reger's music is its complex and dense musical structure. Despite writing tonal music, Reger often pushes the boundaries of tonality so far that all sense of formal organization is seemingly imperceptible. In this dissertation, I offer what I observed to be a new way of discerning Reger's motivic relationships and formal structures within and between movements. There are three primary tools and methods I incorporated to make these observations: Schoenberg's developing variation; melodic contour analysis as discussed by Elizabeth West-Marvin and Diana Deutsch; and Janet Schmalfeldt's motivic cyclicism stemming from internal themes. In this dissertation I examine five different musical works by Reger: D minor Piano Quartet, Clarinet Quintet, Piano Concerto, String Quartet, op. 121 and E minor Piano Trio, op. 102. My analysis shows how Reger relies on melodic contours of his motives to connect musical moments across entire movements and entire works with multiple movements. These motives are developed and often mark structurally significant moments providing the organization often perceived as missing in Reger's music.

The Divine Coming of the Light is a memoir-in-essays that covers an experience, from 2007 to 2010, when I lived in Kosuge Village (population 900), nestled in the mountains of central Japan. I was the only foreigner there. My memoir uses these three years as a frame to investigate how landscape affects identity. The book profiles who I was before Japan (an evangelical and then wilderness guide), why I became obsessed with mountains, and the fall-out from mountain obsession to a humanistic outlook. The path my narrator takes is one of a mountain hike. I was born in tabletop-flat West Texas to conservative, Christian parents in the second most Republican county by votes in America. At 19, I made my first backpacking trip to the San Juan Mountains of western Colorado and was awed by their outer-planetary-like massiveness. However, two friends and I became lost in the wilderness for three days without cell phones. During this time, an obsession possessed me as we found our way back through the peaks to safety, a realization that I could die out there, yes, but amid previously unknown splendor. I developed an addiction to mountains that weakened my religious faith. Like the Romantic …

This paper examines the relation between banks' dividends and their future financial health. Using banks' Nonperforming Loans Ratio, Loan Loss Provision Ratio, and Z-score as proxies for their financial health, I show that there is a strong positive relation between banks' dividends lagged by one quarter and their financial health in the current quarter. This main finding continues to hold following several additional tests, including the application of an instrumental variable approach, the use of change in dividends as the key independent variable, the exclusion of banks that are subject to stress test, the addition of macroeconomic variables, the exclusion of too-big-to-fail banks, and the exclusion of non-depository banks. I also find that the positive relation between banks' dividends and their future financial health is more pronounced for banks with a higher degree of opacity, a lower Tier 1 capital ratio, and during the 2007-2009 financial crisis. This paper contributes to three strands of the finance literature, including the Risk Reduction Hypothesis of dividend signaling in corporate finance, bank dividend policies, and the determinants of banks' financial stability. First, I show that there is a positive relation between banks' dividends lagged by one quarter and their financial health in the …

Recent increases in stock repurchases among U.S. corporations coupled with a historically low cost of debt since the Global Financial Crisis has created media speculation that firms in recent years are paying for their expanding share buyback programs with debt. Repurchasing stock by increasing leverage, instead of using internal funds, implies that managers may speculate on current low interest rate environments at the expense of shareholders. Recent studies find that stock repurchases are associated with reductions in future firm employment and investments such as capital expenditures and research and development expenses. This study expands on prior studies by evaluating how debt-financed stock repurchases affect firm investment, investigating the likelihood of these repurchases in low interest rate environments and assessing the effects on firm value. Results confirm that, in recent years, debt-financed repurchases have increased substantially and the probability of debt-financed repurchases increases in the presence of low interest rates. This relationship is especially pronounced in the years following the Global Financial Crisis. Debt-financed repurchases are associated with small reductions in firm investment; however, these reductions are significantly less after adjusting for industry conditions. Finally, there is little evidence that the method of financing repurchases affects firm value nor does it …

This inquiry is an autoethnography of my experiences as a Black American male serving as a methods of social studies instructor to preservice teachers. Although some may deem this study as subjective, I have embraced that designation to provide insider information to others that face intersectionality and to inform institutional practices in teacher education programs.

This dissertation examines how parties respond and adapt their behavior to political violence. Building a theoretical argument about strategic party behavior and party capture, I address the following questions: How do parties select and recruit their candidates in regions with high levels of violence and the pervasive presence of VNAs? Do parties respond to violence by selecting certain types of candidates who are more capable of fighting these organizations? Do parties react differently at different levels of government? And finally, how do VNSAs capture political selection across at different levels of government? I argue that in regions where there is high "uncertainty," candidate selection becomes highly important for both party leaders and DTOs. Second, I argue that as violence increases and the number of DTOs also, criminal organizations, as risk-averse actors, will capture candidate selection. I posit that as violence increases, there is a greater likelihood that candidates will have criminal connections. To test my theory, I use the case of Mexico. Violence in Mexico and the presence of criminal organizations across the country has experienced a great deal of variation since the 1990s. In Chapter 2, I find that violence affects the gubernatorial candidate selection of the PRI, PAN …

Female athletes have been established as a high-risk group for disordered eating due to the high prevalence rates of clinical (i.e., 1.9% to 19.9%) and subclinical eating disorders (i.e., 7.1% to 49.2%). To date, only a few studies have examined the long-term stability of eating disorders in collegiate female athletes, a design that will allow examination of change in prevalence rates over time. Additionally, researchers have attempted to identify psychosocial risk factors in the development of disordered eating, but short time frames (e.g., competitive season, one year) during which data was collected have limited their findings. The current study investigated the progression in prevalence of eating disorder classification (i.e., eating disordered [ED], subclinical ED, asymptomatic), pathogenic weight control behaviors (e.g., laxative use, vomiting), and the predictive ability of psychosocial risk factors (e.g., body dissatisfaction, negative affect) from the time in which female athletes were active collegiate competitors (Time 1) to a time six years later, in which the women were retired (Time 2). By Time 2, the women were categorized as asymptomatic (69.9%), subclinical ED (26.9%), and clinical ED (3.1%). The prevalence of those who were disordered (i.e., either subclinical or clinical ED) increased from 22.8% (Time 1) to 30.1% …

Leaders of the 84th Texas Legislature drafted and ratified HB 1164 (2015), prompting the Texas Education Agency to pilot a portfolio assessment option for assessing student writing growth and proficiency. The purpose of this study was to identify the perceptions, characterize the experiences, and identify the forces that influenced initial implementation of the statewide writing pilot. Through interviews with district leaders and the collection of open-ended questionnaires from participating educators, a collective case study method was conducted and allowed for analysis of cross-case themes. The identification of restraining and driving forces affecting implementation of the statewide pilot program provided insight into considerations for next steps in the evaluation of student writing achievement and growth. Three primary perceptions emerged as restraining forces influencing implementation: influences of inadequate funding, inconsistencies of implementation, and navigation of multiple assessment systems. Six primary themes related to driving forces influencing implementation were identified: using sociocultural and authentic methods, engaging in reflective practices, increasing volume and variety of writing opportunities, assessing student growth, aligning methods of instruction and assessment, and reducing stress for students. Effective professional development, dependent upon funding and staffing allocations; two-way channels of communication for participant reflection and feedback; and effective assessment structures must …

This qualitative case study examined the effect of PLCs on teacher self-efficacy, and whether the type of PLC structure on each campus affected efficacy. The overarching research question that guided the study was, to what extent does perceived teacher self-efficacy change as a result of the practice of PLCs? Participants were selected using purposive and convenience sampling. Ten teachers and two principals on two different campuses participated in teacher focus groups and one-on-one principal interviews, respectively. The available literature on the topics of professional development, professional learning, teacher collaboration, and teacher self-efficacy yielded the discovery that collaborative practices can be used to improve a school and/or district or used to enhance positive practices that already occur. This study adds to the body of research as it develops the area of teacher efficacy and influence of PLCs. Using the coding software, NVivo, focus group data were coded into themes and further comparisons were made with categories derived and saturated until conclusions were drawn. The data show teacher self-efficacy increases as a result of PLCs when teachers are able to experience positive feedback from teammates, shared leadership, trust and honesty, and a freedom to fail. For those teachers who are not on …

Skeletal muscle satellite cells are important for muscle repairing and muscle mass growth. For a successful muscle regenerative process, satellite cells have to sequentially undergoing different stages of myogenic process, i.e. proliferative state and differentiation state. To support this process, the presence of different circulating factors, such as immune cells, cytokines, and hormones, at the appropriate time course is critical. Among these factors, hormones, such as testosterone, cortisol, and IGF-1, have shown to play an important role in satellite cell proliferation and differentiation. Studies investigated the effect of testosterone on satellite cell using a supraphysiological dose in human or in cell culture demonstrated that testosterone is critical in satellite cell myogenic process. Due to the anabolic effect of testosterone on muscle, studies had been focused on the physiological means to increase the circulating testosterone concentration in the body to maximize the muscle mass growth from resistance exercise. The acute and transient increase in testosterone has shown to be beneficial to muscle mass growth and strength gain; however, this change in physiological testosterone concentration on satellite cell myogenesis is not known. Therefore the purpose of this dissertation is to first determine the effect of acute change in exercise-induced hormones on satellite …

The accurate evaluation of substance use is a critical component of forensic assessment due to the well-established link between drug use sentencing issues and risk of recidivism. Due to limited resources and chronic time constraints, practitioners typically rely only on self-report measures to assess substance use (SU) patterns. As these measures directly inquire about SU patterns, they remain vulnerable to response distortion. This can lead to ineffective treatment recommendations made to the Court and misuse of resources. The present study investigated the utility of the PAI and SASSI-3 in identifying SU patterns in offenders mandated to a long-term treatment facility. As a second major component, offenders were examined post-release to identify predictors for poor treatment outcomes. Results found the direct questioning approach best identified SU patterns in the present sample. In addition, while statistically significant differences in treatment outcomes were not observed between offenders who endorsed a more severe course of their SU problem versus those who endorsed a much less problematic pattern of use, they were trending in the expected direction. Specifically, offenders who used "hard" drugs regularly (e.g., cocaine, heroin), had more negative consequences directly related to their use (e.g., more arrests, prior treatment), and had a more …

The purpose of this study was to investigate direct and interaction effects of cultural intelligence and social support on the adjustment of international students to U.S. higher education. Hierarchical multiple regression analyses were conducted to test (a) if cultural intelligence was a predictor for adjustment of international students to U.S. higher education; (b) if social support was a predictor for adjustment of international students to U.S. higher education; and (c) if there was an interaction effect between cultural intelligence and social support on international students' adjustment to U.S. higher education. The participants included 262 international students from a southwestern university. The results found only social support from the university was a significant predictor of international students' adjustment. There was no interaction effect between cultural intelligence and social support from any sources on international students' adjustment.
