Thermal Transport Properties Enhancement of Phase Change Material by Using Boron Nitride Nanomaterials for Efficient Thermal Management

Description: In this research thermal properties enhancement of phase change material (PCM) using boron nitride nanomaterials such as nanoparticles and nanotubes is studied through experimental measurements, finite element method (FEM) through COMSOL 5.3 package and molecular dynamics simulations via equilibrium molecular dynamics simulation (EMD) with the Materials and Process Simulations (MAPS 4.3). This study includes two sections: thermal properties enhancement of inorganic salt hydrate (CaCl2∙6H2O) as the phase change material by mixing boron nitride nanoparticles (BNNPs), and thermal properties enhancement of organic phase change material (paraffin wax) as the phase change material via encapsulation into boron nitride nanotubes (BNNTs). The results of the proposed research will contribute to enhance the thermal transport properties of inorganic and organic phase change material applying nanotechnology for increasing energy efficiency of systems including electronic devices, vehicles in cold areas to overcome the cold start problem, thermal interface materials for efficient heat conduction and spacecraft in planetary missions for efficient thermal managements.

Thermal Transport Modeling in Three-Dimensional Pillared Graphene Structures for Efficient Heat Removal

Description: Pillared-graphene structure (PGS) is a novel three-dimensional structure consists of parallel graphene sheets that are separated by carbon nanotube (CNT) pillars that is proposed for efficient thermal management of electronics. For microscale simulations, finite element analyses were carried out by imposing a heat flux on several PGS configurations using a Gaussian pulse. The temperature gradient and distribution in the structures was evaluated to determine the optimum design for heat transfer. The microscale simulations also included conducting a mesh-independent study to determine the optimal mesh element size and shape. For nanoscale simulations, Scienomics MAPS software (Materials And Processes Simulator) along with LAMMPS (Large-scale Atomic/ Molecular Massively Parallel Simulator) were used to calculate the thermal conductivity of different configurations and sizes of PGS. The first part of this research included investigating PGS when purely made of carbon atoms using non-equilibrium molecular dynamics (NEMD). The second part included investigating the structure when supported by a copper foil (or substrate); mimicking production of PGS on copper. The micro- and nano-scale simulations show that PGS has a great potential to manage heat in micro and nanoelectronics. The fact that PGS is highly tunable makes it a great candidate for thermal management applications. The simulations were successfully conducted and the thermal behavior of PGS at the nanoscale was characterized while accounting for phonon scattering the graphene/CNT junction as well as when PGS is supported by a copper substrate.

Crafting Downtown Denton: An Exploration of Craft Beer Consumption as an Activity in Denton, Texas

Description: Craft beer as a cultural phenomenon coincided with the revitalization of downtown Denton, Texas. Much of the existing literature on craft beer and its relation to place focuses on breweries rather than bars. This exploratory study aims to explain why people consume craft beer, what factors influenced its popularity in Denton despite little beer production, and to explore considerations for the promotion of Denton as a craft beer destination and making downtown an inclusive space. Data was collected through interviews, participant observation, and a survey. Findings indicated that craft beer consumption in Denton is largely related to perceptions of community, localism, and knowledge seeking. The ethos of the craft beer industry closely aligned with participants' perceptions of Denton as a city.

Using Kidpower® Social Narratives to Teach Individuals with Autism about Bullying

Description: Individuals with autism spectrum disorder (ASD) are at an increased risk to be victims of bullying due to the core characteristics of the disorder. Prior research has focused on understanding bullying from the perspectives of individuals with ASD, parents, and practitioners through interviews and questionnaires. However, limited evidence exists using interventions to teach individuals with ASD about how to identify and respond to bullying. This study employed Kidpower® bullying narratives to teach individuals with ASD how to identify and respond to various bullying scenarios. Kidpower was selected to provide practitioners with a pre-established curriculum to utilize, rather than creating materials for each student. A multiple probe design across three participants was utilized to (a) teach individuals with ASD how to identify and respond to bullying drawings on Kidpower narratives, and (b) add an experimental study to the limited literature base pertaining to strategies for teaching about bullying to individuals with ASD. A fourth participant was also included as a case study. Progress for all participants was measured using the percentage of correct responses to 10 questions. Three out of four participants reached the mastery criterion of 90% over two consecutive sessions. Sessions for the fourth participant concluded after seven intervention sessions due to the COVID-19 pandemic. Many modifications were made to the original study design including changing the wording of the dependent variable and using more simple stories. No modifications were made to the actual stories. This study indicates the Kidpower narratives are helpful in teaching individuals with ASD who also meet certain criteria based on verbal comprehension. However, additional information is necessary in order to assess understanding of bullying.

The Influences of a Topographically and Functionally Unrelated Operant on Response Allocation under Concurrent Continuous Reinforcement Schedules

Description: In the experimental analysis of behavior, response allocation is typically studied under concurrent interval schedules, with two response alternatives, in a static environment. The natural environment of the unfettered organism, however, is dynamic insofar as even frequently visited environments are rarely identical from encounter to encounter. Additionally, natural environments usually offer more than two concurrently available behaviors that are often scheduled for reinforcement contingent on rate of responding. The purpose of this study was to determine how the addition or removal of a third response alternative affected response allocation between two topographically dissimilar operants on independent concurrent ratio schedules in a dynamic environment. Results indicate that the addition of the third operant served to temporarily suppress response rates of the first two operants but had no or only minor and inconsistent effects on relative allocation. The reintroduction of the third operant in a new location again suppressed response rates in three of four subjects and slightly shifted response allocation for one subject. Highly individual anecdotal patterns could be seen in tangential observations of each of 4 subjects. The results suggest the possibility that new alternatives have temporary effects on response bias, and that these effects may be variable and dependent on details of individual history and stimulus control.

How a Schenkerian Analysis May Inform the Interpretation and Performance of J. S. Bach's Lute Music on the Guitar Using Selective Movements of Bach Lute Suite No. 4 in E Major (BWV1006A) as a Demonstration

Description: Continuing the discussion of interpreting J. S. Bach's lute music on the guitar, this dissertation seeks to demonstrate that Schenkerian analysis can assist the modern classical guitarist to better understand Bach's music. In particular, the Schenkerian approach provides an important methodology for studying Bach's music in depth, and then guiding performance practice on the guitar. Although there are many books and articles about transcribing, interpreting and performing Bach's music on the guitar, they do not apply Schenkerian analysis to guitar performance. This research will fill in the lacuna in this field, while promoting music scholarship and enhancing the performance practice of classical guitarists.

Navigating Polyamory and the Law

Description: My research explores what laws, such as laws surrounding immigration, child custody, and divorce, negatively affect polyamorous individuals in the U.S. and how people's perceptions of barriers differ along lines of gender-sexual-racial-class identities. My applied research is conducted for my client, a CNM-friendly attorney in D.C. I investigate the experience of polyamorous people that use lawyers they perceive as consensually non-monogamous (CNM)-friendly. I probe what it means to be "CNM-friendly," how one promotes oneself as a CNM-friendly lawyer to potential clients and the world at large, and the relationship between being a CNM-friendly lawyer and activism.

MISSION (Making Inquiries into the Significance of Safety, Identity, Observations, and Needs) for Warfighters

Description: This paper examines the concept of safety as it encompasses the personal and technological spheres as imagined by a group of active duty service members, veterans, a police officer, and civilians, as well as the agency exercised by those with military or police backgrounds when it comes to safety technology. A group of seventeen individuals took part in a battlefield simulation to test a wearable junctional tourniquet created by ARMR Systems, LLC, an innovative advancement in tourniquet technology. After the simulation, participants were interviewed, surveyed, and took part in a focus group to determine not only product suitability but also to explore the underlying reasons for their recommendations for product changes. Results showed that those with military or police background performed safety rituals prior to duty and exercised agency in the desire to obtain the best possible personal safety devices and technology to be used for themselves and their comrade-in-arms. All participants expressed concerns for their safety in regards to technology in general, specifically, the hacking and use of personal data and what is perceived as lack of governmental oversight. Almost all of the changes to improve product safety, comfort, and utility were adapted. The topics discovered during the course of this research proves a need for safety product testing from an applied anthropological perspective.

A Mixed-Method Sequential Explanatory Study of Fundamental Motor Skills Competence of Underserved Preschool Children

Description: This dissertation investigated the roles of early childhood fundamental motor skills (FMS) competence on physical, cognitive, and psychosocial health outcomes among underserved preschoolers in Head Start, and examined parental influence on their children's FMS competence. An explanatory sequential mixed methodology was used to examine the predictive strength of FMS competence on physical, cognitive, and psychosocial health outcomes among 216 underserved preschoolers from six Head Start centers (Mage = 4.32, SD = 0.63; girls 56.5%). This methodology allowed for a follow-up qualitative aspect to explore the influence of parents' perceptions and behaviors on their child's FMS competence and health outcomes in a subsample of eight parent–child dyads who demonstrate high or low FMS competence in the quantitative data. The results of this dissertation suggest that preschoolers' FMS competence, especially locomotor skills, were associated with and predicted various health outcomes in sedentary behavior (β = -0.21), light physical activity (β = 0.23), executive function (β = -0.21), and perceived motor competence (β = 0.34). No significant influences of FMS competence on moderate-to-vigorous, body fatness, HRQoL were found (p > 0.05). We also found that positive parental influences (role modeling, support, and facilitation) were observed more often among preschoolers in the high FMS competence group. In addition, preschoolers with single, divorced, or young parents (age range 18–24) tended to show low FMS competence. The analysis of children's drawing pictures also indicated differences in images related to the moments when they played games or sports with parents based on their FMS competence levels. Practical implications and future research direction are discussed.

Immigrant Children's Perspectives of Books that Share Stories of Early School Experiences

Description: Guided by the importance of children's voices and perspectives, this study aims at finding the immigrant children's perspectives of books that share stories of early school experiences of immigrant children. Before working with children, there was a careful selection process and analyzing of the three picture books chosen for the study using critical content analysis and childism lenses. The participants are three Arab immigrant children at the age of 6 who are bilingual and attended school in the U.S for one year, at least. With acknowledgement to reader-response theory, the data collection process started with an introductory home visit, followed by three individual interactive read-aloud sessions using interviews, audio records, and observations. The data collection involved field notes of non-verbal responses of the participants and these notes supported analysis of the eight transcripts. Thematic analysis is used in analyzing the data of each story, followed by identifying finding themes across all three stories. The seven themes found across all three stories are discussed in the final chapter and include: Children can have empathy for characters, understand social injustices in the stories, be agents to change injustice in the stories, and are curious about different cultures. The children's personal stories shared during this research are the most valuable outcome because they reflect the real experiences of those most affected by the research topic. The study also explains how listening to immigrant children's personal stories is an act that supports justice and helps to fight against any kind of prejudice those children might face. The study emphasizes that children have the ability to engage in sophisticated conversations about themselves and their life experiences through the use of appropriate tools combined with believing in the children's rights.

Document and Information Experience in Virtual Zenanas: An Exploration of a Diaspora Small World

Description: The word diaspora is currently understood as the large scale voluntary movement of people, along with capital and goods due to the mechanisms of globalization. Adopting a diaspora, gender and leisure perspective, this dissertation looked at the information and document experiences of a particular fan community of women belonging to the Indian diaspora and the online spaces created and occupied by them (fan fiction blogs which can be viewed as book clubs). The study also looked at memory making and documenting of the same as a part of document experience, resulting in what can be termed as "serendipitous memory archives." The blogs hosting fan fiction and the mediated practices they support were viewed as documents for the study. The online spaces were conceptualized as small worlds and the theoretical framework used for the study consisted of a preliminary model of a small world (based on literature review and my understanding of the world under study), information experience as a concept as well as document experience models. The results show that social ties play a big role in the information and document experience, while memory making and documenting of the same are also seen to happen as part of the document experience. The results also show that adopting a document perspective enables us to see the myriad ways in which information is experienced, freeing us from considering as information only that which helps us in meeting a purpose or which fills a gap. Implications and suggestions for future research are discussed.

Identification and Characterization of a Mutation Causing Stunted Growth in Arabidopsis that is Linked to Phosphate Perception

Description: Plant yield is an agronomic trait dependent on the transport of photosynthate from mature source leaves to sink tissues. Manipulating phloem transport may lead to increased yield, however in a previous study, Arabidopsis thaliana overexpressing sucrose transporter AtSUC2 in the phloem resulted in stunted growth and an apparent P-deficiency. In the course of further characterizing the phenotype and identifying the causative mutation, this research included 1) reverse genetics to test genes hypothesized to modulate carbon-phosphate interactions; 2) whole genome sequencing to identify all T-DNA insertions in plants displaying the phenotype; 3) genetic crosses and segregation analysis to isolate the causative mutation; and 4) transcriptomics to capture gene-expression profiles in plants displaying the phenotype. These phenotypes were traced to a T-DNA insertion located on chromosome 4. Transcriptomics by RNA-Seq and data analysis through bioinformatics pipelines suggest disruptions in metabolic and transport pathways that include phosphate, but do not support a direct role of well-established phosphate acquisition mechanisms. Gene At1G78690 is immediately downstream of the T-DNA insertion site and shows modestly increased expression relative to wild type plants. At1G78690 encodes O-acyl transferase, which is involved in processing N-acylphosphotidyl ethanolamine (NAPE) to N-acyl ethanolamine (NAE). Exogenous NAE application causes stunted growth in specific conditions. From the experiments described herein, At1G78690 emerges as the strongest candidate for causing the observed phenotypes.

Unlocking Digital Literacy: A Multiple Case Study of Digital Literacy Instruction and the Interactive Decision Making of Teachers

Description: The rapid expansion of computers and digital technology requires citizens to be digitally literate. Teachers must prepare students for a digital world despite the lack of consensus on a definition or its components. This multiple case study explored the digital literacy instruction and interactive decision making of teachers with varied levels of expertise. Each participant completed a survey and the General Decision Making Style Questionnaire prior to a series of interviews and classroom observations. Findings from a qualitative analysis of the data suggest variations in the use of digital literacy components during instruction and that skills are related to one another. Findings also indicate similarities and differences in interactive decision making and teaching expertise behaviors related to instruction. Based on these findings, recommendations to better promote digital literacy are directed toward teachers, administrators, teacher preparation institutions, and future researchers. Current events emphasize the need for increased efforts in turning the key of digital literacy for students.

Bohuslav Martinů's Oboe Concerto, H. 353: A New Piano Reduction of the Orchestral Score

Description: Bohuslav Martinů's "Concerto for Oboe and Small Orchestra" is one of the most frequently played pieces in the oboe repertoire. For this reason, it is often played with the piano reduction instead of the orchestra in oboe recitals. However, the existing piano reductions include many errors and discrepancies from the orchestral score, misrepresent the orchestration, sometimes fail to make the oboe entries clear, and tend to be unplayable for pianists. Moreover, the scores were published after the composer's death without him supervising the final editing. I have prepared a new, playable piano reduction to represent the orchestration more faithfully and help pianists work with their soloists more easily. Based on the work of Martin Katz, a prominent collaborative-pianist, I establish four principles for creating a new piano reduction. After scrutiny of the deficiencies of existing piano reductions, I suggest solutions for making the passages in question practical and bringing out the leading voices clearly so that the soloist can join in as easily as playing with an orchestra. To aid in reflecting the orchestral texture that Martinů created, I include abbreviated instrument names in many passages to help pianists to understand how to create balance. I have changed some passages completely to make the sound closer to the orchestral texture. All changes and suggestions are based on the orchestral score and its layout. This simplified and practical piano reduction should help pianists have more enjoyable and more successful collaborations with their soloists.

Analysis of the Cytochrome P450 and the UDP-Glucuronosyltransferases Families and Vitamin D3 Supplementation in Anoxia Survival in Caenorhabditis elegans

Description: Alteration in diet and knockdown of detoxification genes impacts the response of C. elegans to oxygen deprivation stress. I hypothesized that feeding worms a vitamin D3-supplementation diet would result in differential oxygen deprivation stress response. We used a combination of wet lab and transcriptomics approach to investigate the effect of a vitamin-D3 supplemented diet on the global gene expression changes and the anoxia response phenotype of C. elegans (Chapter 2). C. elegans genome consists of 143 detoxification genes (cyp and ugt). The presence of a significant number of genes in these detoxification families was a challenge with identifying and selecting specific cyp and ugt genes for detailed analysis. Our goal was to understand the evolution, phylogenetic, and expression of the detoxification enzymes CYPs and UGTs in C. elegans (Chapter 3). We undertook a phylogenetic and bioinformatics approach to analyze the C. elegans, detoxification family. Phylogenetic analysis provided insight into the association of the human and C. elegans xenobiotic/endobiotic detoxification system. Protein coding genes in C. elegans have been predicted to be human orthologs. The results of this work demonstrate the role of C. elegans in the identification and characterization of vitamin D3 induced alterations in gene expression profile and anoxia response phenotypes and the identification of human orthologs for the detoxification enzymes and provides insight into the gene expression pattern.

A Consensual Qualitative Analysis of Counselor Educators' Experiences Incorporating Neuroscience

Description: Neuroscience is a relevant topic for counseling and counselor education, and it is a required area of competency for accredited counseling education programs. Despite this required competency, current counseling literature scarcely addresses neuroscience in counselor education. I have designed the present study to address this scarcity by exploring counselor educators' experiences of incorporating neuroscience into the counselor education curriculum using a consensual qualitative research (CQR) approach. The purpose of this study is to create a foundational understanding of (a) what elements of neuroscience counselor educators are currently including in their courses, and (b) the experience of counselor educators with teaching neuroscience. I interviewed eight counselor educators about their experiences learning and teaching neuroscience. Six domains emerged from the interviews: (1) participants' background and experience, (2) influence of neuroscience on participants' teaching, (3) personal, academic, and professional responses to neuroscience, (4) ethical concerns and recommendations for neuroscience, (5) areas of interest and future research in neuroscience, and (6) counseling literature and publication in neuroscience. The information shared by the participants will contribute to future research of teaching effectiveness and outcomes using neuroscience in counselor education.

Tribo-Corrosion of High Entropy Alloys

Description: In this dissertation, tribo-corrosion behavior of several single-phase and multi-phase high entropy alloys were investigated. Tribo-corrosion of body centered cubic MoNbTaTiZr high entropy alloy in simulated physiological environment showed very low friction coefficient (~ 0.04), low wear rate (~ 10-8 mm3/Nm), body-temperature assisted passivation, and excellent biocompatibility with respect to stem cells and bone forming osteoblast cells. Tribo-corrosion resistance was evaluated for additively manufactured face centered cubic CoCrFeMnNi high entropy alloy in simulated marine environment. The additively manufactured alloy was found to be significantly better than its as-cast counterpart which was attributed to the refined microstructure and homogeneous elemental distribution. Additively manufactured CoCrFeMnNi showed lower wear rate, regenerative passivation, less wear volume loss, and nobler corrosion potential during tribo-corrosion test compared to its as-cast equivalent. Furthermore, in the elevated temperature (100 °C) tribo-corrosion environment, AlCoCrFeNi2.1 eutectic high entropy alloy showed excellent microstructural stability and pitting resistance with an order of magnitude lower wear volume loss compared to duplex stainless steel. The knowledge gained from tribo-corrosion response and stress-corrosion susceptibility of high entropy alloys was used in the development of bio-electrochemical sensors to sense implant degradation. The results obtained herewith support the promise of high entropy alloys in outperforming currently used structural alloys in the harsh tribo-corrosion environment.

Sounding the Ancestors: Sangpuy Katatepan Mavaliyw and the Ancestral Spirit Imaginary

Description: Sangpuy Katatepan Mavaliyw is a Taiwanese Aboriginal pop artist of the Pinuyumayan ethnic group. His albums have been acclaimed by Aboriginal listeners and Han-Taiwanese mainstream music critics for capturing the traditional Aboriginal sound and evoking the presence of the ancestors. In this thesis, I explore why Sangpuy's songs are understood to evoke ancestral spirit imaginary using a semiotic approach. I compare his music to traditional Pinuyumayan music such as pa'ira'iraw and shamanic songs to demonstrate how he uses similar musical gestures to evoke the sense of ancestral spirits. Other sonic elements such as the inclusion of the soundscape of a Pinuyumayan village provides a direct link to the lived experiences of the Pinuyumayan. I also position Sangpuy's music in the broader context of nationalism in Taiwan and how Sangpuy uses his music to negotiate Aboriginal issues such as land rights and environmentalism. Through this analysis, I demonstrate how Taiwanese Aborigines are incorporating their Indigenous ideology into popular music to carve out a space for themselves in Taiwanese society and garner more support for Indigenous rights in Taiwan.

Processing, Pre-Aging, and Aging of NiTi-Hf (15-20 at%) High Temperature Shape Memory Alloy from Laboratory to Industrial Scale

Description: The overarching goal of this research was to generate a menu of shape memory alloys (SMAs) actuator materials capable of meeting the demands of aerospace applications. Material requirements were recognized to meet the demand for high temperature SMAs with actuating temperatures above 85 °C and provide material options capable of performing over 100K actuation cycles. The first study is a preliminary characterization for the down selection of Ni-rich NiTiHf15 compositions chosen for a more in-depth examination of the nano-precipitation and evolution of the H-phase. To make this selection, the effect of Ni content in Ni-rich NiTiHf high temperature shape memory alloys (HTSMAs) on processability, microstructure, and hardness was analyzed for three compositions (Ni50.1TiHf15, Ni50.3TiHf15, Ni50.5TiHf15). Each composition was characterized under three conditions: homogenized, 25%, and 50% thickness reduction through hot-rolling. The second study emphasized the processing and aging response of an industrially produced, hot-extruded Ni50.3Ti29.7Hf20 (at%) HTSMA. The samples were sectioned into two halves with half remaining as-extruded and the other half hot-rolled to a 25% reduction in thickness. A portion of both conditions underwent conventional aging for 3 hours at various temperatures ranging from 450-750 °C, and the other portion was pre-aged for 12 hours at 300 °C followed by conventional aging treatments. After processing, the samples were characterized by differential scanning calorimetry (DSC), Vickers hardness (HV) testing, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and synchrotron radiation X-ray diffraction (SR-XRD). The relationship between the introduction of texturing, pre-aging, and aging on Ni-rich and high Hf-content compositions was investigated.

Evaluating Variables that Influence Research Staff Performance

Description: Performance analysis, based on operant analysis of behavior, has been utilized since the 1960s to investigate behavioral skills or deficits in the workplace. One type of analytical tool is Carr et al.'s Performance Diagnostic Checklist- Human Services (PDC-HS). This functional assessment allows investigators to pinpoint causes of performance issues (e.g., a training issue, task clarification/prompting, insufficient resources/materials/processes, or performance consequences/effort/competition). Typically, the PDC-HS is used with clinicians and therapists. The purpose of this study is to extend Carr et al. by evaluating the PDC-HS in assessing the clinical performance of graduate-level research assistants working at a specialized clinic for the assessment and treatment of severe behavior disorders. For each participant, three supervisors, the study investigator and the participants themselves completed the PDC-HS with respect to the performance concern. Results of the PDCH-HS showed variability in congruence across the three groups of respondents. Due to the occurrence of the global coronavirus disease 2019 (COVID-19) pandemic during the study's investigation, the project was modified to assess different clinical performance involving safety procedures. The PDC-HS was re-administered to assess participants' cleanliness behavior and a subsequent targeted intervention was designed. Results showed no improvement of performance for 4/4 participants in the nontargeted intervention for clinic session performance and an increase for 1 participant in the targeted intervention for the cleanliness performance. Implications of PDC-HS results and limitations are discussed.

An Examination of Business Professors' Experiences with Remote Teaching under COVID-19: Lessons Learned for the Future

Description: During the COVID-19 pandemic in the spring of 2020, universities throughout the United States closed their campuses and transitioned their face-to-face courses to remote learning. The unprecedented transition created a unique learning and teaching environment. This case-based qualitative study investigates the experiences of business professors from a prestigious school of business that taught during the transition. Findings derived from the digital Likert survey instrument completed by all the business faculty and semi-structured interviews of selected business faculty. Some of the topics of the survey and interviews included communicating with students, developing the learning management system course content, delivering asynchronous material, delivering synchronous classes, and providing instructional feedback. Findings included a significant growth in business professor's perceived skillset in almost all topics, an interest in further developing skills, and an interest in adopting the new skills in future face-to-face courses. Through NVIVO analysis of the interviews, four thematical elements were identified: faculty efficacy, faculty training, course delivery, rapport. The study investigated a deep wholistic view of the data presented and provided an extensive in-depth description of the social phenomenon. A practical framework for incorporating the identified themes was developed for business schools needing to establish and maintain online business programs.

Information Seeking Behaviors of Transitioning Veterans When Job Hunting in North Texas

Description: This study explored a part of our population that can be misunderstood, marginalized, and underserved: veterans who are seeking to transition from the military to employment in North Texas. At the time of this research (before the COVID-19 pandemic), overall unemployment in North Texas was only 3.9%.Veteran unemployment was calculated at approximately the same before considering the underemployed veterans or those who have given up finding employment (and before the COVID-19 global pandemic), and that calculation likely exceeds 16-18% according to the Texas Workforce Commission. By understanding the information-seeking behaviors of the veteran population targeting North Texas for future employment, their ability to find useful information for successful relocation, attainment of employment, and the resources that enables their sense-making processes, the services provided to veterans seeking employment can be improved. Further understanding can be gained by using a qualitative approach that references Dervin's sense making model (SMM) as the framework. The revelations and conclusions can be used to improve existing programs, inspire new programs, and provide answers that are useful to the Veteran's Administration (VA), other veteran-focused organizations, policymakers, non-profits who serve veterans, veterans themselves, and future employers who enable successful transitions by providing satisfying and inclusive employment opportunities for veterans.
