Description: 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… more

Characterization, Analysis, and Optimization of Rotary Displacer Stirling Engines

Description: 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, an… more

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

Description: 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 … more

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

Description: 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 condense… more

Conceptual Barriers to Decarbonization in US Energy Policy

Description: 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 t… more

Creative Networks: Toward Mapping Creativity in a Design Classroom

Description: 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-net… more

Deep Learning Approach for Sensing Cognitive Radio Channel Status

Description: 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 techno… more

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

Description: 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… more

An Empirical Investigation into the Value of Credit Lines

Description: 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… more

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

Description: 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 … more

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

Description: 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 critic… more
