An understanding of factors that contribute to Complex Post Traumatic Stress Disorder (CPTSD) is of considerable importance to inform the prevention and treatment of the disorder. Moreover, gaining a better understanding of the factors that contribute to the etiology of CPTSD is of interest since most research to date focuses on the etiology of PTSD. Therefore, the purpose of the current study is to test the hypothesized prediction between childhood exposure to violence, childhood attachment, current interpersonal factors, and CPTSD symptoms. Using data from a community clinic and shelter serving victims of domestic violence and sexual assault, a partial least squares path analysis approach was employed to test the model’s strength in predicting contributing factors of CPTSD. Results support the proposed model, however, an alternative and more parsimonious model was found to be superior and revealed relationships between interpersonal variables and CPTSD. Specifically, women who reported child abuse and poor attachment with either parent, a perceived lack of current emotional and tangible support, and recent intimate partner violence (IPV) also reported symptoms of CPTSD. However, other variables, such as adult attachment avoidance and anxiety did not influence IPV or CPTSD as expected. Ultimately, the current findings lend support for Herman’s …

During the transition to college, emerging adults are expected to develop independence and increase individual responsibility as they live away from home for the first time. Modern electronic communication has enabled emerging adults to maintain frequent, daily contact with the parent, a pattern of communication Hofer refers to as an “electronic tether.” This study examined the link between parenting style and the development of independence of first year, first semester college students. Although these students were in frequent contact with their designated parent, no correlation between frequency of communication and parenting style or independence was found. Both authoritative and helicopter parenting significantly positively predicted attitudinal independence. However, permissive parenting functioned as a significant negative predictor. Authoritarian, permissive, and helicopter parenting significantly positively predicted conflictual independence. However, authoritative parenting functioned as a significant negative predictor. Both authoritative and helicopter parenting significantly positively predicted emotional and functional independence.

The need to spur innovation and improve student performance initiated the formation of, under different legislative acts, charter schools that include variations of traditional public schools. With the enthusiasm and level of investment going into the formation of charter schools, it is necessary to explore whether these schools have achieved their objectives. This study explored whether Texas open enrollment charter schools perform bettered compared to Texas public schools. The study applied a causal comparative quantitative research design. School data on graduation and dropout rates, college preparation, attendance rates, and overall performance were analyzed quantitatively. Student achievement data available for statistical analysis includes student performance on the Texas Assessment of Knowledge and Skills (TAKS) state assessment from 2007 to 2011. Data analysis for race, special programs, at risk, economically disadvantaged, and limited English proficiency was incorporated. Descriptive statistics and analysis of variance techniques were included in the data analysis. The analysis extended to post hoc tests to determine variables that caused variation. The study found Texas open-enrollment charter schools had more African American students but fewer Whites compared to public schools. Students in public schools performed better than those in charter schools, and Whites yielded the best performance. Charter schools had …

The English diction texts by Madeleine Marshall and Kathryn LaBouff are two ofthe most acclaimed manuals on singing in this language. Differences in style between the two have separated proponents to be primarily devoted to one or the other. An in-depth study, comparing the precepts of both authors, and applying their principles, has resulted in an understanding of their common ground, as well as the need for the more comprehensive information, included by LaBouff, on singing in the dialect of American Standard, and changes in current Received Pronunciation, for British works, and Mid-Atlantic dialect, for English language works not specifically North American or British. Chapter 1 introduces Marshall and The Singer’s Manual of English Diction, and LaBouff and Singing and Communicating in English. An overview of selected works from Opera America’s resources exemplifies the need for three dialects in standardized English training. Chapter 2 reviews notational and diction resources, and use of the International Phonetic Association’s alphabet (IPA). Chapter 3 directly compares Marshall and LaBouff’s views of the importance of the unstressed syllable, often schwa [ә] or open I [ɪ], as vital to allowing the audience to understand the flow of the sung text, and contrasts their differences regarding < …

Assessment of executive functioning in neurodevelopmental disorders (e.g., autism) is a crucial aspect of neuropsychological evaluations. The executive functions are accomplished by the supervisory attentional system (SAS) and include such processes as inhibition, switching, and planning. Autism spectrum disorder (ASD) tends to present similarly to other neurodevelopmental disorders (e.g., ADHD). For example, ASD and ADHD may share similar etiological underpinnings in the frontostriatal system of the frontal lobe. Research on executive functioning in ASD has been mixed, thus the precise nature of executive functioning deficits in ASD remains equivocal. In recent years, simulation technologies have emerged as an avenue to assess neurocognitive functioning in individuals with neurodevelopmental disorders impacting frontostriatal function. Simulation technology enables neuropsychologists to assess neurocognitive functioning within a testing environment that replicates environments in which the subject is likely to be in everyday life, as well as present controlled, real-world distractions, which may be better able to tap “hot” executive functions. A Virtual Classroom Continuous Performance Test (CPT) has been used successfully to assess attention in individuals with neurodevelopmental disorders impacting frontostriatal function. The current study aimed to investigate executive functioning in individuals with high functioning ASD using a new construct driven Stroop assessment embedded into the …

The purpose of this descriptive study was to discover Texas middle school choir directors’ perceptions and applications of multicultural education in their classrooms. Three research questions guided this investigation: (1) What were middle school choir director’s perceptions about multicultural music education?; (2) How did middle school choir directors apply multicultural music pedagogy in their classrooms?; and (3) How did middle school choir directors perceive professional development opportunities in multicultural music education? Texas middle school choir directors perceived that the purpose of multicultural music was to expose students to different cultures and diverse worldviews through music. Teachers listed several social and musical benefits of studying multicultural music including broadening musical horizons, cultural appreciation, and expansion of student worldviews. Teachers consciously programmed multicultural music for most of their concerts, and some chose literature based on their students’ cultural backgrounds. Although most teachers tried to make multicultural music experiences genuine for students, authenticity was the foremost pedagogical concern regarding multicultural music pedagogy. Teachers tended to utilize a combination of music concept and sociocultural approaches when teaching multicultural music by comparing multicultural music to Western music and using classroom discussions to discuss social issues that lend context to the music. Professional development opportunities in …

Today’s military encompasses a wide variety of families who are affected by deployments in multiple and complex ways. Following deployments, families must reconnect in their relationships and reestablish their way of life. Appropriate and effective communication during this time is critical, yet many military couples struggle with this process. Moreover, student service members/veterans and their families are in a unique position. In addition to coping with changes in their marital relationship, student veterans may feel isolated or unsupported on college campuses, often experiencing anxiety, depression, posttraumatic stress, or suicidality. The current study seeks to bridge the gap between the military family literature and the student service member/veteran literature by examining how deployment experiences, mental health issues, and communication patterns influence post-deployment relationship adjustment among student veterans. Analyses tested whether communication style and/or current mental health concerns mediate associations between combat experiences and couples’ relationship adjustment, as well as between experiences in the aftermath of battle and relationship adjustment. Results suggest that although posttraumatic stress is significantly related to deployment experiences among student veterans, participants report no significant negative effects of deployment on relationship adjustment. Communication style, however, was significantly associated with relationship adjustment, and a lack of positive communication was …

The aim of this study was to examine to what extent Social Structure and Social Learning Theory (SSSL) explains delinquent behaviors among Turkish adolescents. While Social Structure and Social Learning (SSSL) Theory have been examined quite frequently in the criminology and sociology literature, the present study is unique as it tests the theory in Turkey, a context with a mixed Islamic and Secular cultural structure. The data originates from a survey conducted in Istanbul in 2008 by the Icelandic Centre for Social Research and Analysis (ICSRA) under the auspices of their Youth in Europe project. The sample includes 2,445 Turkish high school students. The dependent variable includes a 13-item delinquency scale, and the independent variables consist of differential association, costs and rewards of differential reinforcement, definitions, imitation, differential location in the social structure, and differential social location of groups. The statistical analyses were conducted using a negative binomial regression approach. Results demonstrated that differential association (peer delinquency) is positively associated with delinquent behaviors among Turkish adolescents. In addition, there is a significant and positive relationship between norms/beliefs that favor delinquency and delinquent behaviors. Moreover, parental reaction, a measure of differential reinforcement, has a negative impact on delinquency. Imitation variables, which …

The purpose of this study was to examine the effect of post-resistance exercise alcohol ingestion on LPS-stimulated production of IFNγ, TNF-α, IL-1β, IL-6, IL-8, and IL-10. Recreationally resistance-trained men (n = 10, 25 ± 3 yr, 177 ± 7 cm, 83.8 ± 15.7 kg, 14.8 ± 8.5% body fat) and women (n = 8, 23 ± 2 yr, 161 ± 3 cm, 59.5 ± 6.0 kg, 26.5 ± 3.0% body fat) completed the study. Participants visited the laboratory for an initial visit at which time they were screened, familiarized with procedures, and had their 1-repetition maximum (1RM) back squat tested. Subsequently, participants visited the laboratory 2 more times and completed 2 identical heavy resistance exercise bouts (6 sets of 10 repetitions of 80% 1RM back squat) after which a beverage, either containing alcohol (alcohol condition, ALC; 1.09 g EtOH per kg fat free mass) or water (placebo condition, PLA), was administered. Blood samples were collected before exercise (PRE), and at 3 hours (3h) and 5 hours (5h) after exercise. Samples were stimulated with lipopolysaccharide (LPS) and cultured overnight. Supernatant was collected and analyzed for IFNγ, TNF-α, IL-1β, IL-6, IL-8, and IL-10. A significant (p < 0.05) main effect for time …

This thesis examines the policies and procedures created during and after the First World War that provided the foundation for how the United States commemorated its war dead for the next century. Many of the techniques used in modern times date back to the Great War. However, one hundred years earlier, America possessed very few methods or even ideas about how to locate, identify, repatriate, and honor its military personnel that died during foreign conflicts. These ideas were not conceived in the halls of government buildings. On the contrary, concerned citizens originated many of the concepts later codified by the American government. This paper draws extensively upon archival documents, newspapers, and published primary sources to trace the history of America’s burial and repatriation policies, the Army Graves Registration Services, and how American dead came to permanently rest in military cemeteries on the continent of Europe. The unprecedented dilemma of over 80,000 American soldiers buried in France and surrounding countries at the conclusion of the First World War in 1918 propelled the United States to solve many social, political, and military problems that arose over the final disposition of those remains. The solutions to those problems became the foundation for how …

Police officers are allowed considerable discretion within the criminal justice system in addressing illegal behaviors and interpersonal conflicts. Broadly, such resolutions fall into two categories: formal (e.g., arrest) and informal outcomes. Many of these interventions involve persons who have historically faced stigmatization, such as those who have mental disorders, criminal histories, or both (i.e., mentally disordered offenders). On this point, stigma generally includes discriminatory behavior toward the stigmatized person or group and can be substantially influenced by internal and external attributions. In addition, researchers have suggested that internal attributions lead to punishing behaviors and external attributions lead to helping behaviors. The current study examined attributions about offender behavior made by police officers in an effort to evaluate the effectiveness of Corrigan’s model. Specifically, this study investigated the effects of officer attributions on their immediate decisions in addressing intentionally ambiguous and minor offenses. Officers provided one of two vignettes of a hypothetical offender who was either mentally disordered or intoxicated and provided their anticipated resolution of the situation. Encouragingly, disposition decision differed by offender condition, with a substantially higher rate of arrests for the intoxicated offender (i.e., the external condition). Corrigan’s model was initially successful for both offender conditions, but was …

Over the last several decades, researchers have documented how impaired reasoning by adult offenders impeded the intelligent waiver of Miranda rights. Logically, it stands to reason that juveniles – who are developmentally less mature and have less life experience than their adult counterparts – would possess even greater impairment, thereby heightening their risk for invalid Miranda waivers. Juvenile Miranda research supports this notion; with some researchers finding that psychosocial maturity, among other factors, affect a juvenile’s understanding of their rights. Yet, relatively few studies have examined its relation to Miranda reasoning and decision-making. Thus, the current study investigated the specific role of maturity in juveniles’ Miranda comprehension and reasoning. Participants included 236 legally-involved juveniles recruited from either a juvenile detention center or a juvenile justice alternative education program. The effects of psychosocial maturity were examined on a variety of Miranda-related measures and assessed a broad range of Miranda abilities. It was found that, in general, immature juveniles performed more poorly on all Miranda measures as compared to their mature counterparts. However, the impact of maturity varied considerably depending on the ability. Specifically, maturity was most important in the context of Miranda reasoning. As a novel addition to the literature, the …

Prior research on incumbent firm response to radical technological innovation identifies firm, technology, and environmental factors associated with incumbents’ performance after a technology shift. What remains unexplored are factors affecting choice of response made before a technological shift occurs. Such ex ante choices are important intermediate outcomes affecting long-term performance outcomes. Competitive considerations may be influential inputs in choice processes because technological innovation is often related to competitive strategy. The resulting research question for this study is: What role do competitive considerations play in incumbent firms’ ex ante strategic choices in response to potentially radical technological innovations? Findings from a survey of key informants in the electronics industry whose firms face a potential technological disruption (n=120) suggest that incumbents’ response choices are affected by competitor-related orientations and by perceptions of relative strength of their strategic assets. Limited support is found for a moderating effect of perceptions of the competitive environment. The results of this study extend theory on incumbent response to radical technological change by shedding light on the influence of competitor interdependence. Findings also suggest the importance of strategic choice as an intermediate variable in understanding incumbents’ long-term performance. Research examining choice factors at varied stages of a technology’s …

Optical character recognition (OCR) software has advanced greatly in recent years. Machine-printed text can be scanned and converted to searchable text with word accuracy rates around 98%. Reasonably neat hand-printed text can be recognized with about 85% word accuracy. However, cursive handwriting still remains a challenge, with state-of-the-art performance still around 75%. Algorithms based on hidden Markov models have been only moderately successful, while recurrent neural networks have delivered the best results to date. This thesis explored the feasibility of using a special type of feedforward neural network to convert freeform cursive handwriting to searchable text. The hidden nodes in this network were grouped into clusters, with each cluster being trained to recognize a unique character bigram. The network was trained on writing samples that were pre-segmented and annotated. Post-processing was facilitated in part by using the network to identify overlapping bigrams that were then linked together to form words and sentences. With dictionary assisted post-processing, the network achieved word accuracy of 66.5% on a small, proprietary corpus. The contributions in this thesis are threefold: 1) the novel clustered architecture of the feed-forward neural network, 2) the development of an expanded set of observers combining image masks, modifiers, and feature …

During team decision-making practices information is often shared among team members as part of the decision making process. Knowledge sharing involves one team member sharing information so that other team members can encode the knowledge to make their own mental representation of the new information (Huan & Jiang, 2012). Unfortunately, the literature has shown that new information is not always shared between team members during decision making processes (Stasser & Titus, 1985). When teams make decisions without considering all the information available poor decisions can result. This research study tests a team conceptual model derived by Turner (2013) addressing attitudes toward knowledge sharing. Structural equation modeling was conducted to test a portion of Turner’s (2013) team conceptual model. The tested model included the independent variables of psychological safety, team conflict, team cohesion, and transactive memory systems. The dependent variable for the dissertation was knowledge sharing.

The wind octet was a popular ensemble of the classical period. In 1782, the Viennese Emperor formed a wind octet which specialized in playing opera arrangements. This music was used primarily as a form of background entertainment for dinners. This guide analyzes and compares the works of several well-known arrangers from the classical period in order to demonstrate arranging styles of the time. The arrangers of the period were often the performers of these various wind octets who were writing specifically for the players in their own ensembles. The style of Mozart’s original wind music is also discussed, in contrast to the arrangements of his works made by others. This guide is intended for serve performers of today as a tool to learn the art of arranging in an historical style. Idiosyncrasies of the classical-period wind instruments are discussed, as they relate to the style of wind arranging. The role of the contemporary arranger is compared with that of the classical period, and the case is made for the need for more contemporary arrangements of classical works using period arrangers as models.

The purpose of this descriptive study was to first identify to what extent first-year college violinists physically struggle with the vibrato motion, and further, to identify physical problems within the motion that are contributing to their challenges during the learning process. The 16 participants in this study were chosen randomly from the College Music Society Directory of Music Faculties in Colleges and Universities (2013-2014 edition). Participants completed a questionnaire of 32 quantitative and qualitative questions addressing the vibrato of their 2013-2014 first-year violinists. 62% of participants’ first-year students had a physical problem with vibrato, 70% of participants’ students were working on correcting physical problems in vibrato during lessons. Participants also reported that 15% of their students were not able to create a vibrato motion at all. Almost all professors (n=15) indicated that students with a problematic vibrato were too tense in parts of the arm or hand and this negatively affected the motion and thus, the sound. Specific problems also included vibrato being too narrow, but rarely too wide, vibrato being too fast or too slow caused by tension, problems with when and how vibrato was being applied, problems with maintaining intonation before or during use of vibrato, and problems …

Traditional use of the multiple-choice question rewards a student for guessing. This technique encourages rote memorization of questions to pass a lengthy exam, and does not promote comprehensive understanding or subject correlation. This begs the question; do we really want question memorizers to operate the machinery of our industrialized society? In an effort to identify guessing on answers during an exam within a safety-critical aviation pilot training course, a qualitative research study was undertaken that introduced a confidence-based element to the end-of-ground-school exam followed by flight simulator sessions. The research goals were twofold, to clearly identify correct guesses and also provide an evidence-based snapshot of aircraft systems knowledge to be used as a formative study aid for the remainder of the course. Pilot and instructor interviews were conducted to gather perceptions and opinions about the effectiveness of the confidence-based assessment tool. The finding of overall positive interview comments confirmed that the pilots and flight instructors successfully used the confidence-based assessments as intended to identify weak knowledge areas and as aids, or plans, for their remaining study time. The study found that if properly trained and administered—especially through a computer-based medium—a robust confidence-based assessment tool would be minimally-burdensome while offering worthwhile …

The most well-known events and occurrences that caused the American Revolution are well-documented. No scholar debates the importance of matters such as the colonists’ frustration with taxation without representation, the Boston Massacre, the Boston Tea Party, and the Coercive Acts. However, very few scholars have paid attention to how the 1772 English court case that freed James Somerset from slavery impacted American Independence. This case occurred during a two-year stall in the conflict between the English government and her colonies that began in 1763. Between 1763 and 1770, there was ongoing conflict between the two parties, but the conflict temporarily subsided in 1770. Two years later, in 1772, the Somerset decision reignited tension and frustration between the mother country and her colonies. This paper does not claim that the Somerset decision was the cause of colonial separation from England. Instead it argues that the Somerset decision played a significant yet rarely discussed role in the colonists’ willingness to begin meeting with one another to discuss their common problem of shared grievance with British governance. It prompted the colonists to begin relating to one another and to the British in a way that they never had previously. This case’s impact on …

The term emerging adulthood was coined during the 21st century to describe human development between adolescence and adulthood, during the ages of 18-25 (Arnett, 2000). During this stage, individuals can explore life areas. Emerging adults beginning college have a unique opportunity to form their identities and develop value systems (Hauser & Greene, 1991). With increasing autonomy, college students have possibilities for positive development and risk; values may be imperative in that differentiation. Furthermore, value systems are believed to play a major role in decision-making (Schwartz, 1992). Parents are influential in values development (Simpson, 2001; Steinberg & Sheffield Morris, 2001). During emerging adulthood, individuals have opportunities to notice discrepancies between their parents’ value system and society. Thus, emerging adults evaluate and choose personal values, which may or may not be similar to those of their parents, peers, or broader culture. Findings from this study indicate female caregivers’ parenting styles and closeness of the parent-child relationship have significant direct effects on the degree to which values are freely chosen. Specifically, Authoritarian parenting style (β = -.43 B = -1.70, p < .001), Authoritative parenting style (β = .12, B = .53, p < .001), and Emotional Support (β = .30, B = …

Torture survivors find difficulty navigating through an unfamiliar healthcare and social service system. Many survivors who already face Post Traumatic Stress Disorder (PTSD), anxiety, and depression also endure a secondary threat which leads to re-traumatization through the struggles of acculturation. The aim of this study is to determine: 1. Identify differences and assumptions between service providers’ and clients’ definitions of self-sufficiency; 2. Examine prominent barriers to self-sufficiency that survivors encounter; 3. Pinpoint the survival strategies that survivors use in order to cope with life in DFW; 4. Determine what resources CST staff, area service providers, and survivors feel need to be improved for CST and the DFW metroplex.

Emissions of air pollutants from non-conventional sources have been on the rise in the North Texas area over the past decade. These include primary pollutants such as volatile organic compound (VOC) and oxides of nitrogen (NOx) which also act as precursors in the formation of ozone. Most of these have been attributed to a significant increase in oil and gas production activities since 2000 within the Barnett Shale region adjacent to the Dallas-Fort Worth metroplex region. In this study, air quality concentrations measured at the Denton Airport and Dallas Hinton monitoring sites operated by the Texas Commission on Environmental Quality (TCEQ) were evaluated. VOC concentration data from canister-based sampling along with continuous measurement of oxides of nitrogen (NOx), ozone (O3), particulate matter (PM2.5), and meteorological conditions at these two sites spanning from 2000 through 2014 were employed in this study. The Dallas site is located within the urban core of one of the fastest growing cities in the United States, while the Denton site is an exurban site with rural characteristics to it. The Denton Airport site was influenced by natural gas pads surrounding it while there are very few natural gas production facilities within close proximity to the Dallas …

The “infrastructure” of quadratic fields is a body of theory developed by Dan Shanks, Richard Mollin and others, in which they relate “reduced ideals” in the rings and sub-rings of integers in quadratic fields with periodicity in continued fraction expansions of quadratic numbers. In this thesis, we develop cubic analogs for several infrastructure theorems. We work in the field K=Q(), where 3=m for some square-free integer m, not congruent to ±1, modulo 9. First, we generalize the definition of a reduced ideal so that it applies to K, or to any number field. Then we show that K has only finitely many reduced ideals, and provide an algorithm for listing them. Next, we define a sequence based on the number alpha that is periodic and corresponds to the finite set of reduced principal ideals in K. Using this rudimentary infrastructure, we are able to establish results about fundamental units and reduced ideals for some classes of pure cubic fields. We also introduce an application to Diophantine approximation, in which we present a 2-dimensional analog of the Lagrange value of a badly approximable number, and calculate some examples.

This thesis examines formal organization in ground-bass works. While it is true that many or even most works of the ground-bass repertoire are variation sets over a ground, there also exist many ground-bass works that are not in variation form. The primary goal of this thesis is to elucidate the various ways in which such non-variation formal organizations may be achieved. The first chapter of this work discusses the general properties of ground basses and various ways that individual phrases may be placed in relation to the statements of the ground. The second chapter considers phrases groupings, phrase rhythm, and the larger formal organizations that result. The third chapter concludes this study with complete analyses of Purcell’s “When I am laid in earth” from Dido and Aeneas and Delanade’s “Jerusalem, convertere ad dominum Deum tuum” from his setting of the Leçons de ténèbres.
