An Alternative Operationalization of Betrayal Trauma using Perceived Betrayal

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

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

Description: 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… more

Biomedical Semantic Embeddings: Using Hybrid Sentences to Construct Biomedical Word Embeddings and its Applications

Description: Word embeddings is a useful method that has shown enormous success in various NLP tasks, not only in open domain but also in biomedical domain. The biomedical domain provides various domain specific resources and tools that can be exploited to improve performance of these word embeddings. However, most of the research related to word embeddings in biomedical domain focuses on analysis of model architecture, hyper-parameters and input text. In this paper, we use SemMedDB to design new sentences … more

Biopedagogy of Rumination and Regurgitation

Description: Regurgitating test answers, needing more time to digest a reading, or being spoon fed information are just a few of many digestive metaphors currently used in education. In taking seriously the use of these metaphors, I suggest that humans recognize a connection, on some level, between the mental act of taking in and processing knowledge and the physical act of digestion, yet in educational discourse, these processes are more often than not cast in a negative light. The following philosophical … 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

Creating the Character of North Texas: Demographics and Geography, 1841-1861

Description: Several historians have identified North Texas as constituting a unique cultural region in antebellum Texas, due to the more limited cotton and slave economies and greater opposition to secession. Different settlement patterns have been put forward as an explanation for the distinct "character" of North Texas, with North Texas being portrayed as being settled largely by migrants from the Upper South while the rest of the state was primarily settled by Lower Southerners. The argument rests on th… 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

Development of an Optical Carbon Dioxide Sensor and Modeling of Metal-Metal Interactions for Sensor Applications

Description: An investigation of luminescent sensing has been presented. Neutral Red, a common pH luminescent sensor, was shown to be an effective carbon dioxide sensor for the first time. Sensing experiments were performed both through fluorometric and fluorescent microscopy studies, giving rise to the possibility of carbon dioxide sensing for biological applications. Neutral Red was benchmarked against the well-established carbon dioxide sensor Pyranine (8-hydroxypyrene-1,3,6-trisulfonic acid trisodium sa… more
