An Alternative Operationalization of Betrayal Trauma using Perceived Betrayal (open access)

An Alternative Operationalization of Betrayal Trauma using Perceived Betrayal

There are many identified factors that correlate with whether an individual experiences adverse symptoms following a traumatic event. Research indicates that betrayal, where the victim is betrayed by another individual, may be one of these factors. Betrayal Trauma Theory (BTT) posits that betrayal during trauma increases the likelihood of developing adverse psychological symptoms. BTT objectively dichotomizes traumas as high betrayal or low betrayal traumas based on details of the event. Though literature finds those who experience high betrayals experience more severe symptoms of PTSD, depression, anxiety, and dissociation than those who experience low betrayals, this objective classification is limited as it is based solely on the circumstances of the trauma and does not give the victim the option of indicating whether they felt betrayed. We believe perceptions of betrayal, whether the event meets the objective criteria of betrayal put forth by BTT or not, is an important predictor of trauma-related outcomes. This study (N = 244) found that perceived betrayal predicts symptoms of PTSD and depression independently, as well as when controlling for objective betrayal, dependence on the perpetrator, event centrality, anxiety, and dissociation. These findings indicate perceived betrayal is a unique construct that should be included in the operationalization …

An Analysis of Dave Holland's Free Improvisation in "Waterfall" and Its Pedagogical Applications for Bassists in Avant-Garde Performance (open access)

An Analysis of Dave Holland's Free Improvisation in "Waterfall" and Its Pedagogical Applications for Bassists in Avant-Garde Performance

This research investigates a microcosm of the free jazz/free improvisation environment of the 1970s in "Waterfall," from the album Dave Holland/Sam Rivers Vol. 1. This recording features Dave Holland and Sam Rivers exhibiting highly developed improvisational language and effortless interaction. The purpose of this investigation is to create pedagogical material for bassists who are unfamiliar and/or uncomfortable with performing in an improvisational style that exists separately from the rigid, instrumental role hierarchy of common practice jazz. An analysis of musical elements including melody, rhythm, form, and energy through systems of musical contour, musical forces, and form analysis reveal constituent patterns that can be isolated. These patterns are codified and presented as pedagogical suggestions to assist in the practice of free improvisation.

An Analysis of Student Perceptions of Teaching Effectiveness for Instructors Who Teach the Same Course in the Same Semester in Both Online and Face-to-Face Formats (open access)

An Analysis of Student Perceptions of Teaching Effectiveness for Instructors Who Teach the Same Course in the Same Semester in Both Online and Face-to-Face Formats

There is an increasingly number of students taking online classes in lieu of or in addition to the traditional face-to-face format. With this trend, there are questions that naturally come to the surface. The biggest question being "is teaching in the online arena just as effective as the face-to-face arena?" This dissertation aims to pursue that line of questioning by analyzing students' perceptions of the teaching effectiveness for instructors who teach the same course in both an online and face-to-face format in the same semester. The data are analyzed through the lens of the social capital theory. Social capital has never been applied to the classroom before as its focus has traditionally been on community development. However, social capital theory addresses interpersonal relationships and their impact on knowledge sharing behavior. This theory identifies three dimensions, which appear to have a parallel track with the student evaluation components; each is analyzed against each other. These dimensions include structured, cognitive and relational and are compared to the components of the student evaluation tool, which includes organization and explanation of materials, learning environment and self-regulated learning.

Analyzing Learning Acquisition and Retention in a WebVR Environment (open access)

Analyzing Learning Acquisition and Retention in a WebVR Environment

The primary purpose of this study was to determine if WebVR enhances the knowledge retention regarding mechanical components of high-risk moving machinery, specifically elevators. There were 23 participants divided into a treatment group and comparison group. The treatment group used WebVR to take a virtual elevator machine room tour while the comparison group studied printed images of the same elevator machine room. These alternative activities were conducted prior to a field trip to a real elevator machine room. Gains in knowledge pre to post were measured and compared between the treatment and comparison groups. The research findings showed an overall gain in knowledge for the participants in the elevator bootcamp. More in depth analysis showed the treatment group exhibited significant gains for six of the ten knowledge areas while the comparison group exhibited significant gains in three of the ten targeted knowledge areas. The treatment group gained more knowledge on components higher than eye-level while the comparison group scored better on components that were below eye-level or on the floor. Both groups were seen actively engaged in the field trips. The treatment group members exposed to the virtual reality elevator machine room frequently referred to what they saw in the …

A Case Study of Leadership Supports of Job-Embedded Professional Development (open access)

A Case Study of Leadership Supports of Job-Embedded Professional Development

Professional development is a critical part of school improvement and enhancing teacher quality; yet there is limited literature about how principals design and lead effective professional development systems. The research activities in this qualitative single case study explored the leadership practices at one successful school implementing job-embedded professional development. A conceptual framework relating Hallinger's leadership for learning construct to professional development helped frame the research. Collected data included participant interviews, a focus group interview, observations, and relevant document analysis. These data were analyzed using a general inductive method to identify the prevailing leadership characteristics. The major themes that emerged during analysis were: (a) vision and goals, (b) high expectations, (c) structures and resources, (d) communication, (e) monitoring progress and providing recognition, (f) focused and ongoing professional development, (g) differentiated professional development, (h) trust and professionalism, (i) culture of learning and growth, (j) building capacity, and (k) collaboration. These themes aligned well with the initial conceptual framework. These findings support the concept that leadership for learning may have implications for school leaders trying to implement effective job-embedded professional development.

Characterization, Analysis, and Optimization of Rotary Displacer Stirling Engines

Access: Use of this item is restricted to the UNT Community
This work focuses on an innovative Rotary Displacer SE (RDSE) configuration for Stirling engines (SEs). RDSE features rotary displacers instead of reciprocating displacers (found in conventional SE configurations), as well as combined compression and expansion spaces. Guided by the research question "can RDSE as a novel configuration achieve a higher efficiency compared to conventional SE configurations at comparable operating conditions?", the goal of this study is to characterize, analyze, and optimize RDSE which is pursued in three technical stages. It is observed the RDSE prototype has an optimum phase angle of > 90° and thermal efficiency of 15.5% corresponding to 75.2% of the ideal (Carnot) efficiency at the source and sink temperatures of 98.6° C and 22.1° C, respectively. Initial results indicate that 125° phase angle provides more power than that of the theoretically optimum 90° phase angle. The results also show comparable B_n and significantly higher W_n values (0.047 and 0.465, respectively) compared to earlier studies, and suggest the RDSE could potentially be a competitive alternative to other SE configurations. Furthermore, due to lack of a regenerator, the non-ideal effects calculated in the analytical approach have insignificant impact (less than 0.03 kPa in 100 kPa). The clearance volume in …

Child-Centered Canine-Assisted Therapy: An Investigative Look at Integrating Therapy Dogs into Child-Centered Play Therapy (open access)

Child-Centered Canine-Assisted Therapy: An Investigative Look at Integrating Therapy Dogs into Child-Centered Play Therapy

Play therapy and animal-assisted therapy are two specialized modalities within the field of counseling. Child-centered play therapy (CCPT) is a specific theoretical approach to play therapy that regards the therapeutic relationship as the primary healing factor. With much empirical support, CCPT is considered an effective mental health treatment option for working with children. Animal-assisted therapy in counseling (AAT-C) is acknowledged in the literature as a supplemental treatment modality to an existing counseling practice. Although past researchers have shown support for AAT-C as well as CCPT, there is a current dearth of literature examining the integration of these approaches. The present study sought to understand the approach of incorporating a therapy dog into child-centered play therapy while maintaining theoretical consistency. Using a constructivist grounded theory approach, I facilitated child-centered canine-assisted play therapy (C3APT) services for four children and reviewed the sessions with expert supervisors in AAT-C and CCPT. Three major themes emerged from the data: (a) principles of C3APT, (b) procedures of C3APT, and (c) relational dynamics. Implications for clinical practice and training of both therapy dogs and C3APT practitioners are also discussed.

Computational Development of Trimetallic Cyclotrimers for Gas-Filtration Applications through Non-Covalent Interactions

Access: Use of this item is restricted to the UNT Community
Photophysical properties of an array of various polyaromatic hydrocarbons were benchmarked with B3LYP, M06 and B97D methods coupled with Pople and CEP-31G(d) basis sets. Results from the benchmark show the importance of diffuse basis sets when modeling the electronic properties of highly conjugated systems and provide qualitative reliable accuracy with certain levels of theory. B97D and M06 are applied to modeling pyrene adducts governed by non-covalent interactions in both gaseous and condensed states to reproduce experimental spectra. DFT calculations with both B97D and M06 functionals show qualitatively and quantitatively that pyrene dimer is a stronger π–base as compared to its monomer. Binding energies coupled with MEP, PCA and Qzz results show that the difference in π-basicity of the monomer and dimer impacts the supramolecular chemistry involved in adducts formed with super π-acidic silver cyclometallic trimer (CTC). Non-covalent interactions between coinage metal CTCs and ammonia/phosphine substrates is reported. Interactions between these substrates and the facial plane of the π-rich gold CTC reveal a novel interaction, where the typical Lewis acid/base roles are reversed for the substrates. Adducts formed through this type of interaction define typical Lewis bases like ammonia and phosphine as Lewis acids, wherein the partially positive hydrogens coordinate to …

Conceptual Barriers to Decarbonization in US Energy Policy (open access)

Conceptual Barriers to Decarbonization in US Energy Policy

In order to meet emissions targets under the UN Paris Agreement, every nation must decarbonize its energy production. The US isn't reducing energy-related emissions fast enough to meet its targets for keeping overall warming under 2°C above pre-industrial levels. This constitutes a grave injustice to the most vulnerable populations of the world, who are suffering the ill effects of climate change already. The challenge of eliminating fossil fuels from the US energy system is not simply one of technological limitations, however. The aim of this dissertation is to provide an analysis of historical, political, and, most importantly, conceptual barriers to decarbonization of energy in the US. I believe not just our policies and our markets, but our thinking has to change if we are to avoid recapitulating the injustices of the fossil fuel energy system. I argue that energy policy in the US over time has ossified around a narrow conception of energy as fossil energy—as a substance, rather than as a service. I call this the fossil conception of energy (FCE). I follow historical traces of the FCE in three key areas: political discourse in the US, the relationships between the US dollar and OPEC oil (a complex web …

Creative Networks: Toward Mapping Creativity in a Design Classroom (open access)

Creative Networks: Toward Mapping Creativity in a Design Classroom

This study developed new mapping techniques and methodologies for understanding creativity in terms of connectivity and interaction between human and non-human actors in a design classroom. The researcher applied qualitative methods of data collection combining both observation of classroom activities and focus group interviews in order to map a creativity network. The findings indicate that creativity is a complex weather-like system (or what I call "creative climate") composed of many sub-networks and diffused networks. Four interactions emerged from the study: (a) the creative climate is composed of the circulation of bodies and objects forming networks and sub-networks, (b) centers and corners/edges are a measure of connectivity and interaction in classroom space design, (c) roundness is a measure of classroom style and the space of connectivity usage, and (d) plugs-in creativity is a measure of technology consolidation. This study attempted to fill the gap in the literature on creativity and classroom design by explaining the role of non-human actors in shaping the creative climate in the classroom, especially the role of the classroom space itself as an actor. The implication of this study in art education opens a new opportunity for research in designing innovative classrooms. Also, it will allow future …

Deep Learning Approach for Sensing Cognitive Radio Channel Status

Access: Use of this item is restricted to the UNT Community
Cognitive Radio (CR) technology creates the opportunity for unlicensed users to make use of the spectral band provided it does not interfere with any licensed user. It is a prominent tool with spectrum sensing functionality to identify idle channels and let the unlicensed users avail them. Thus, the CR technology provides the consumers access to a very large spectrum, quality spectral utilization, and energy efficiency due to spectral load balancing. However, the full potential of the CR technology can be realized only with CRs equipped with accurate mechanisms to predict/sense the spectral holes and vacant spectral bands without any prior knowledge about the characteristics of traffic in a real-time environment. Multi-layered perception (MLP), the popular neural network trained with the back-propagation (BP) learning algorithm, is a keen tool for classification of the spectral bands into "busy" or "idle" states without any a priori knowledge about the user system features. In this dissertation, we proposed the use of an evolutionary algorithm, Bacterial Foraging Optimization Algorithm (BFOA), for the training of the MLP NN. We have compared the performance of the proposed system with the traditional algorithm and with the Hybrid GA-PSO method. With the results of a simulation experiment that this …

Determining the Diagnostic Accuracy of and Interpretation Guidelines for the Complex Trauma Inventory (CTI) (open access)

Determining the Diagnostic Accuracy of and Interpretation Guidelines for the Complex Trauma Inventory (CTI)

The work group in charge of editing the trauma disorders in the upcoming edition of the International Classification of Diseases (ICD-11) made several changes to the trauma criteria. Specifically, they simplified the criteria for posttraumatic stress disorder (PTSD) and added a new trauma disorder called complex PTSD (CPTSD). To assess the new and newly defined trauma disorders, Litvin, Kaminski and Riggs developed a self-report trauma measure called the Complex Trauma Inventory (CTI). Although the reliability and validity of the CTI has been supported, no empirically-derived cutoff scores exist. We determined the optimal CTI cutoff scores using receiver operating characteristic (ROC) analyses in a diverse sample of 82 participants who experienced trauma and were recruited from an inpatient trauma unit, student veteran organizations, and university classrooms. We used the Clinician-Administered Interview for Trauma Disorders (CAIT) to diagnose the presence of an ICD-11 trauma disorder, and we correlated the results of the CAIT with the Clinician-Administered PTSD Scale for the DSM-5 to establish the convergent validity of the CAIT, r = .945, p < .001. For the ROC analyses, the CTI was used as the index test and the CAIT was used as the criterion test. The area under the curve (AUC) …

District Systematic Supports of an Instructional Coaching Program (open access)

District Systematic Supports of an Instructional Coaching Program

The purpose of this qualitative study was to identify the systems, structures, and behaviors district leaders employ and enact to assist elementary school principals' relationship with their school instructional coach. Through the synthesis of current research, the conceptual framework was developed with a focus on district leadership behaviors and instructional coaching programs. The conceptual framework consisted of professional capital theory, instructional coaching model, and principal leadership skills. This study assessed the perceptions of six instructional coaches, six elementary principals, and three district leaders from Comet ISD regarding the specific behaviors district leaders use to support the relationship between the school principal and instructional coach. The three-part data collection process included document analysis, face-to-face interviews, and focus group interviews to support the triangulation of data. Through the a priori coding process, four themes emerged that identified key district structures and leadership behaviors needed to support the relationship between the school principal and instructional coach: program clarity, principal leadership skills, professional learning opportunities, and culture of continuous learning. This study revealed a specific need to understand program implementation, accountability, and evaluation of the effectiveness of the instructional coaching program in a fast-growth district.

The Effectiveness of Child Parent Relationship Therapy (CPRT) for Fathers (open access)

The Effectiveness of Child Parent Relationship Therapy (CPRT) for Fathers

High levels of quality father involvement in childhood are associated with children's socio-emotional, cognitive, and behavioral wellbeing. However, fathers can experience difficulty in building positive relationships with their kids due to work-life balance, lack of relational experience, and other life stressors. The purpose of this study was to assess the effectiveness of child-parent relationship therapy (CPRT) on fathers' parental empathy, parental stress, and child behavior problems. Though an abundance of literature exists to support the efficacy of CPRT, this was the first study to include a randomized controlled design with an all-male sample. This was also the first CPRT study to include both English and Spanish speaking fathers with intervention offered in both languages. Participants were 30 fathers (22 English, 8 Spanish; 53% Latino, 40% Caucasian, 7% Asian) with children between the ages of 3 and 10 (60% male, 40% female; 57% Latino/a, 37% Caucasian, 6% Asian). Fathers were randomly assigned to the experimental group (CPRT) (n = 14) or waitlist control group (n = 16). Results from 2 (Group) by 2 (Time) repeated measures ANOVAs did not yield statistically significant interaction effects on the dependent variables. However, results indicated a statistically significant main effect for time on each dependent …

An Empirical Investigation into the Value of Credit Lines (open access)

An Empirical Investigation into the Value of Credit Lines

Access to adequate liquidity to finance future investments is an essential element of financial management. The two main questions that this dissertation attempts to answer are (i) what is the net valuation effect of LoC? and (ii) if LoC create value, what are the sources of this value? To answer these questions, I constructed a sample of 85,232 firm-years spanning from 1993 to 2016, with credit line data obtained from Capital IQ and Bloomberg. I investigated the valuation effects of LoC with a methodology extensively used in the analysis of the valuation implications of cash. I used this methodology because cash and LoC are two alternatives to manage liquidity and estimated the changes in shareholders' value associated with changes in existing LoC undrawn balances and on new LoC agreements. The results from this analysis demonstrates a positive association between increases in LoC capacity and shareholder's value. These findings are also obtained in univariate and event study analyses. The results also suggest that LoC create more value for firms that are rich in cash, indicating the LoC and cash are complementary liquidity management tools. I then focused on the sources of the value created by credit lines. I examined whether information …

Ensemble Singing in the Bel Canto Salon Repertory: A Pedagogical Reconsideration

Access: Use of this item is restricted to the UNT Community
Vocal duets have had a long history in the Western classical music tradition. Their use as a teaching resource can be traced back to the Renaissance, where duets were used for the development of singing, performance, and musicianship. In the late 19th and all of the 20th centuries, this pathway of vocal pedagogy has markedly declined. This study proposes a reintroduction of this methodology of teaching, asserting that it provides the collegiate vocal student with maximum opportunity for growth and development in terms of technique, musicianship, ensemble skills, and performance development. Four vocal duets ("La pesca," "Il brindisi," "Il gallop," and "La caccia") of Saverio Mercadante (1795-1870) serve as the point of discussion. These songs from Les soirées italiennes (C.1836), which are representative of the salon culture of the 19th century, are given detailed attention through a discussion of their pedagogical value. Since they are long out of print, a new performance edition is presented.

Event Sequence Identification and Deep Learning Classification for Anomaly Detection and Predication on High-Performance Computing Systems (open access)

Event Sequence Identification and Deep Learning Classification for Anomaly Detection and Predication on High-Performance Computing Systems

High-performance computing (HPC) systems continue growing in both scale and complexity. These large-scale, heterogeneous systems generate tens of millions of log messages every day. Effective log analysis for understanding system behaviors and identifying system anomalies and failures is highly challenging. Existing log analysis approaches use line-by-line message processing. They are not effective for discovering subtle behavior patterns and their transitions, and thus may overlook some critical anomalies. In this dissertation research, I propose a system log event block detection (SLEBD) method which can extract the log messages that belong to a component or system event into an event block (EB) accurately and automatically. At the event level, we can discover new event patterns, the evolution of system behavior, and the interaction among different system components. To find critical event sequences, existing sequence mining methods are mostly based on the a priori algorithm which is compute-intensive and runs for a long time. I develop a novel, topology-aware sequence mining (TSM) algorithm which is efficient to generate sequence patterns from the extracted event block lists. I also train a long short-term memory (LSTM) model to cluster sequences before specific events. With the generated sequence pattern and trained LSTM model, we can predict …

Examining the Impact of Community Policing on Public Attitudes toward Fear of Terrorism, Resilience, and Satisfaction with Police in the Face of New Terrorism (open access)

Examining the Impact of Community Policing on Public Attitudes toward Fear of Terrorism, Resilience, and Satisfaction with Police in the Face of New Terrorism

This dissertation examines the impact of citizen's perception of community policing on public attitudes toward fear of terrorism, resilience for a future terrorist attack, and satisfaction with the police in the face of new terrorism. In particular, considering the changing nature of terrorism in recent years as a response to the centralized homeland security efforts, this dissertation attempts to develop our understanding about the extent to which community policing could be a strategy in dealing with terrorism fear among citizens, in building up resilience for future terrorist attacks, and to increase citizens' satisfaction with the police in order to enhance the quality of life in the face of new terrorism. Additionally, this dissertation examines the impact of the variation in the level of community policing implementation on public attitudes toward fear of terrorism, resilience for a future terrorist attack, and satisfaction with the police. Data was collected through an online survey conducted in the cities of Arlington and Frisco, Texas. The survey distributed to the citizens through the Amazon Mechanical Turk (MTurk) platform. These cities were selected based on a community policing scale which was created through the help of the Law Enforcement Management and Administrative Statistics (LEMAS) survey. Results …

Examining the Psychological Resiliency of Latino Immigrants in Five Texas Cities: Policy, Economics, and Politics – The Case of the Latino Community (open access)

Examining the Psychological Resiliency of Latino Immigrants in Five Texas Cities: Policy, Economics, and Politics – The Case of the Latino Community

This dissertation examines the impact of city-level characteristics (immigration-friendliness index, unemployment rate, and the percentage of Democrat Party votes) on the psychological resiliency of Latino immigrants. In the light of increased attention on the immigrant issue throughout the world, this study aims to develop our understanding of the factors that have the effect on the resiliency of immigrant populations. This dissertation examines these different characteristics by examining five different cities in Texas: Austin, Dallas, Fort-Worth, Houston, and San Antonio. The survey was distributed through the Amazon Mechanical Turk (MTurk) to those individuals who define themselves Hispanic or Latino. Results suggest that the city characteristics have a significant impact on the resiliency of Latino immigrants suggesting that local governments have a potential capability to increase the resiliency of the immigrant groups in the United States by embracing the notion that immigrants should be integrated into the fabric of the local community.

An Exploration of Professional Training and Professional Practice: Title IX Administrators and Meaning Making

Access: Use of this item is restricted to the UNT Community
Federal law requires institutions to designate campus-based administrators to oversee Title IX processes and investigations, but little is known about how these have been professionally prepared for their roles. The purpose of this study was to understand the professional preparation, educational experiences, and professional training of Title IX administrators and to understand their independence in decision-making in those roles. This study utilized qualitative content analysis and a social constructionist approach to analyze data generated from interviews and document analysis. Sixteen current and former Title IX administrators (investigators, deputy coordinators, coordinators) provided their perspectives on their professional training and development. Using frameworks of work/professional socialization and professions theory, findings illustrated complex systems for knowledge acquisition, professional preparation, and professional socialization based on factors including resources, institutional context, and role prioritization. Participants' formal education, formative experiences, position-specific training, and professional organizations training all served as preparation for their roles. Discussion focused on implications for graduate programs, training and trainers, institutions and supervisors, the field of higher education, and current Title IX practitioners regarding professional preparation for these roles.

An Exploration of the Changing Role of Principal Supervisors

Existing literature provides newly identified responsibilities of the principal supervisor but lacks in information about how districts should strategically spearhead the process of initiating, implementing, and managing the changes to the role of the supervisor. In this study, I examined the behaviors and actions of one school district's executive-level leaders as they shifted the position of the principal supervisor. Findings could contribute to a new area of research in how district leaders may navigate and manage the complicated process of initiating and managing the changes to the principal supervisor's role.

Fatigue and Inhibitory Control: A Test of Key Implications of an Emerging Analysis of Behavioral Restraint Intensity (open access)

Fatigue and Inhibitory Control: A Test of Key Implications of an Emerging Analysis of Behavioral Restraint Intensity

Agtarap, Wright, Mlynski, Hammad, and Blackledge took an initial step in providing support for the predictive validity of a new conceptual analysis concerned with behavioral restraint - defined as active resistance against a behavioral impulse or urge. The current study was designed to partially replicate and extend findings from their study, employing a common film clip protocol and a procedure for inducing low- and high levels of fatigue. Analyses indicated that key cardiovascular (CV) responses rose with the evocativeness of the film clip among low fatigue participants but fell with the evocativeness of the film clip among high fatigue participants. This is consistent with the prediction that high fatigue participants would put forth more restrain intensity than low fatigue participants when confronted with the less evocative clip, but less restraint intensity than low fatigue participants when confronted with the more evocative clip. Behavioral restraint performance - quantified as duration of facial non-neutrality - was also consistent with predictions, being impaired by fatigue under high- but not low evocativeness conditions. Findings support the broad theoretical suggestion that fatigue influence on behavioral restraint is multifaceted, dependent on the perceived magnitude of the impulse or urge experienced and the importance of resisting it.
