Collaborating on Scholarship: Best Practices for Team Research Projects
Article on collaborating on scholarship. Collaborating on scholarship has the potential to provide many advantages, including benefiting from others’ expertise, reinforcing accountability, and providing motivation. However, working with others is tricky—consider compatible work habits, receptivity to criticism, and commitment to fulfill responsibilities. Decisions to be made include where to publish, in what order authors’ names will appear, and how the manuscripts will be written. Who will coordinate? Who will write what? Who will revise? Also, consider how to address problems—missed deadlines, less-than-stellar quality, how to say “no” in the future, and more. This version is the authors' manuscript.

Dynamic Assessment as an Approach to French Pronunciation Instruction
This thesis is focused on dynamic assessment (DA), an instructional approach based on Vygotskian sociocultural theory, applied to French pronunciation instruction, which can be neglected or inconsistent in the foreign language curriculum. DA aims to combine instruction and assessment into a cooperative, mediated approach in which the mediator works with the learner to identify and develop emergent abilities. These emergent abilities can appear in what is often referred to as the zone of proximal development (ZPD), or the difference between what a learner can do independently and what he/she can do with mediation, which in the present study was the difference between what the participant could pronounce correctly with or without mediation. In carrying out an individual DA session with a learner, the author aimed to find suggestions of potential benefits by applying DA to French pronunciation instruction and gain a more detailed understanding of the learner's performance than is generally possible from a traditional assessment, which is totally devoid of mediation for the sake of validity and reliability. The study includes a discussion of some potential benefits and limitations related to the use of DA for teaching French pronunciation to intermediate L2 learners based on what was observed in …

Use of a Virtual Reality Gaming System to Improve Balance in Individuals with Chronic Brain Injury
Wii Fit U games utilize a Wii Balance Board™ (WBB) in a manner that can provide precise feedback contingencies similarly to some forms of balance rehabilitation, thereby potentially increasing the dose of quality therapy with or without the presence of a therapist during post-brain injury rehabilitation. Additionally, an engaging video-game could improve treatment adherence, a critical aspect of making positive functional gains, by potentially increasing the rate and quality of reinforcement embedded in therapy. The present study had three aims: (1) develop a rigorous behavioral therapy for improving balance in individuals living with chronic brain injury using a Wii Fit U game and the WBB; (2) evaluate the program's effects on balance measures using a within-subject experimental design; and (3) assess social validity of behavioral gains by evaluating the program's effects on participant's "subjective balance confidence" (i.e., their Activities-Specific Balance Confidence (ABC) scores). A reversal design is proposed for use with primary study participants, wherein the experimental gameplay condition and no intervention condition are alternated for 6 to 10 weeks. A similar design was used in a truncated fashion with pilot participants, and a multiple baseline design was used with follow-up pilot participants. It was expected that participants would exhibit …

The Relationship between Self-Directed Informal Learning Videos and Financial Literacy
The purpose of this convergent mixed method study was to determine whether or not there is a difference in the perceived and actual financial literacy scores of millennials. Exploring the following research questions and hypotheses helped to expand knowledge around actual financial literacy and several other characteristics, including perceived financial literacy, especially among millennials (individuals born between 1981 and 1996): RQ1: What is the difference between millennials' actual and perceived financial literacy scores? RQ2: To what extent do socioeconomic status, gender, and having a bank account predict millennials' financial literacy scores? H0: There is no relationship between millennials' socioeconomic status, gender, banking status and their financial literacy scores. RQ3: What video delivery methods (if any) are millennials using to gain financial literacy knowledge in informal learning environments? Millennial participants (N = 207) were asked to complete a survey. Participants' perceived financial literacy scores were higher than their actual financial literacy scores. While males had higher perceived financial literacy ratings, females accounted for the majority of participants who scored four or above on a 5-point scale for actual financial literacy. Although, the null hypothesis was incorrect, the independent variables used in the ANOVA tables accounted for less than 15% of financial …

Seeking Method in the Madness: Demystifying Students' Multimodal Digital Composing Processes
The study of writing has moved through process and product movements. The rapid introduction of technology into classroom spaces has provided new platforms and opportunities for students to integrate multiple modes of communication into a single act of composing. While there is an acknowledgment that digital multimodal composition is a highly complex act and set of processes, much of the literature and investigation into this digital turn in composing has largely been product focused versus process focused. This exploratory qualitative case study examined how students compose using digital tools and were driven by questions about what activities in which they engage and what patterns exist in how those activities come together. Using a combination of data sources including screen capture video, think-aloud protocols, and retrospective surveys, eleven process activity categories emerged from analysis including selection, text entry, manipulation, referencing, environment setting, review, contemplation, waiting, breaks, transition, and completion. Process activity categories then informed the inductive determination of four tendencies that impact how process activity comes together during participant acts of composing. Participants displayed as one-dimensional, irresolute, flexible, and perfectionist. Broad patterns related to process activity progression and traditional concepts of print were present in participant composing activity. Viewed together, vague …

High Strain Rate Deformation Behavior of Single-Phase and Multi-Phase High Entropy Alloys
Fundamental understanding of high strain rate deformation behavior of materials is critical in designing new alloys for wide-ranging applications including military, automobile, spacecraft, and industrial applications. High entropy alloys, consisting of multiple elements in (near) equimolar proportions, represent a new paradigm in structural alloy design providing ample opportunity for achieving excellent performance in high strain rate applications by proper selection of constituent elements and/or thermomechanical processing. This dissertation is focused on fundamental understanding of high strain-rate deformation behavior of several high entropy alloy systems with widely varying microstructures. Ballistic impact testing of face centered cubic Al0.1CoCrFeNi high entropy alloy showed failure by ductile hole growth. The deformed microstructure showed extensive micro-banding and micro-twinning at low velocities while adiabatic shear bands and dynamic recrystallization were seen at higher velocities. The Al0.7CoCrFeNi and AlCoCrFeNi2.1 eutectic high entropy alloys, with BCC and FCC phases in lamellar morphology, showed failure by discing. A network of cracks coupled with small and inhomogeneous plastic deformation led to the brittle mode of failure in these eutectic alloys. Phase-specific mechanical behavior using small-scale techniques revealed higher strength and strain rate sensitivity for the B2 phase compared to the L12 phase. The interphase boundary demonstrated good stability without any …

An Instrumental Song without Words about Hope: A Melodic Motivic Analysis of the Third Violin Sonata by Charles Ives (1874–1954)
The American composer Charles Ives is well known for musical quotation/borrowing: composing music with or from pre-existing musical sources, such as folk tunes, hymns, chants, or other composers' works. His Third Violin Sonata is one of few works that used his unique technique of cumulative setting with only hymn tunes. For analysis of his instrumental music, the text of the hymn tunes is generally disregarded, as the compositions are for instruments. Ives' Third Violin Sonata is challenging to understand in comparison with other violin sonatas, because it lacks information such as titles and subtitles. Even though Ives never mentioned the piece's meanings or extramusical meanings, almost all the elements of the piece indicate hope as a common theme. This dissertation examines which hymn tunes were quoted in the piece, gives the meanings of the hymn tunes, and discusses how Ives uses these tunes as themes with textual meanings. The study includes a brief life of Ives and his historical circumstances and presents a brief musical analysis. The research should give a better understanding of the piece to performers and others curious about it.

Computational Studies of the Photophysical, Structural, and Catalytic Properties of Complex Chemical Systems
Computational chemistry employs mathematical algorithms, statistics, and large databases to integrate chemical theory with experimental observations. Computational modeling allows us to make predictions concerning molecular properties and reactivity that ultimately lead to accurate assessment of the most important fundamental properties of chemical systems. Advances in theoretical techniques and computer power have dramatically increased the usefulness and importance of computational chemistry as a complement to experimental studies. This is especially relevant to catalytic reactions of industrial importance as well as the analysis of structural properties and the resulting spectroscopic phenomena in what are often otherwise counterintuitive models. This dissertation is a representation of the research I performed during my years as a graduate student in the Chemistry Department at the University of North Texas. My research has examined novel carbenes as efficient organocatalysts, structure-based design and optimization of small molecule drugs, and surveying methods to accurately describe structure and bonding and catalytic abilities of inorganic and organometallic systems. The works presented herein have been published or are awaiting submission to peer-reviewed scientific journals. A variety of computational techniques were employed in studying metal-mediated catalysis and organocatalysis as well as the structural and photophysical properties of systems containing closed-shell transition metal ions.

Examining the Links between Attachment Style, Psychopathic Traits, and Sexuality
Previous literature has identified links between psychopathic trait severity and disturbed styles of attachment on sexual outcomes in adulthood. However, few studies have investigated these domains within one design. Therefore, it is unclear how they may influence each other, given that an association between attachment styles and psychopathic traits has also been previously documented. This study sought to explore the possible role of psychopathic traits upon the association between attachment and sexual outcomes. Participants were sampled from an undergraduate student population at a large university. Data were analyzed using correlational and hierarchical regression analyses, as well as two exploratory path models. Analyses suggested that aspects of attachment and psychopathic trait severity were significantly associated with each other and differentially predicted certain sexual outcomes. Furthermore, results indicated that the effects of attachment avoidance on sexual outcomes were mediated by Factor 1 traits of psychopathy, while the effects of attachment anxiety were mediated by Factor 2 traits. Additionally, it was found that attachment style was linked with contempt, and this was further linked to disturbances in sexual outcomes, which is a novel finding. Implications of the findings, limitations, and future directions are discussed.

Effects of Surface Texture and Porosity on the Corrosion Behavior and Biocompatibility of Pure Zinc Biomaterials for Orthopedic Applications
In this dissertation, small and large NaCl particle-derived surfaces (Ra > 40 microns) were generated on 2D Zn materials, and the surfaces were carefully studied concerning topography, corrosion behavior, and bone cell compatibility. Increases in surface roughness accelerated the corrosion rate, and cell viability was maintained. This method was then extended to 3D porous scaffolds prepared by a hybrid AM/casting technique. The scaffolds displayed a near-net shape, an interconnected pore structure, increasing porosity paralleled to an increased corrosion rate, an ability to support cell growth, and powerful antibacterial properties. Lastly, nano/micro (Rz 0.02–1 microns) topographies were generated on 2D Zn materials, and the materials were comprehensively studied with special attention devoted to corrosion behavior, biocompatibility, osteogenic differentiation, immune cell response, hemocompatibility, and antibacterial performance. For the first time, the textured nonhemolytic surfaces on Zn were shown to direct cell fate, and the micro-textures promoted bone cell differentiation and directed immune cells away from an inflammatory phenotype.

Early Intervention Referral and Service Frequency for Children with Visual Impairments: Experiences from the Field
The purpose of this study was to examine differences in early intervention (EI) referral and service frequency for children with blindness or visual impairment (BVI) and gather information about the practices and experiences of vision professionals across the United States. The study focused on obtaining data from certified teachers of students with visual impairment (CTVI) and certified orientation and mobility specialists (COMS) in the United States. Information collected included descriptive statistics and professional information about EI for children with BVI, and information about the referral process and service frequency for children with BVI during EI. Thirty-three states were represented in the collected data. Of these states, 26 had responses from four or more professionals, the criteria for inclusion in the analyses. Participants provided information based on a researcher-developed survey requesting information related to the procedures used to provide EI services for children with BVI. Questions were adapted from established instruments where possible. Across states, there were some statistically significant differences in CTVIs and COMS reports of procedures regarding the role of professional collaboration, parent/caregiver participation in IFSP meetings, strengths/resources utilized by vision professionals, and challenges parents/families encountered when accessing EI services for their child with BVI. No statistically significant differences …

Investigation of Room Temperature Soft Ferromagnetism in Indium Phosphide Substrate Synthesized via Low Energy Nickel Ion Implantation
In this work, we have utilized an ion beam process known as gettering to migrate implanted Ni ions much deeper into the bulk substrate than their initial projected end of the range. The projected mean depth is known as Rp. The gettering effect is the most crucial part of the fabrication and we have found that for an H fluence of 3x 1016 cm-2 there is a threshold fluence of approximately 7.5 x 1015 cm-2 that cannot be surpassed if the gettering process is to be completed along with the substrate recovered to the high crystalline quality. This hard threshold is due to the gettering process relaxation induced mechanism that is responsible for migrating the Ni to the Rp/2 location while the H is vacating during the thermal annealing process. If the total number of vacancies produced by the H dissociation is not substantially larger than the total number of implanted Ni atoms the Ni will migrate to the Rp location of the Ni implantation at the amorphous and crystalline interface and toward the surface. When the gettering condition is not met the resulting magnetic responses vary from an exceptionally weak ferromagnetic response to not exhibiting a magnetic response. Additionally, …

Freight Forwarder Satisfaction: A Conceptualization and an Empirical Test of Effect on Airport Customer Loyalty and Competitiveness
In 2018, global gross domestic product (GDP) was US$86.3 trillion, and almost a quarter of that value was due to international trade with a value of US$19.6 trillion. Air cargo accounts for about 35 percent of that trade value (approximately US$6.86 trillion). Moreover, from the perspective of the airport sector, air cargo revenue contributes between 20 to 70 percent of airport revenue. The global airport revenue for freight in 2018 was US$250 billion. Despite the interest and research activities surrounding competition and competitiveness of airports and specifically among airlines and passengers, it appears scholars have overlooked research concerning the competitiveness of airports when it comes to air cargo. This study attempts to fill the gap in the supply chain and logistics literature by putting forward a framework and ultimately operationalizing the framework highlighting the pivotal role of air cargo in the supply chain domain and within the global economy. Specifically, the framework is operationalized within the freight forwarding air cargo supply chain domain – providing insight into this important yet understudied phenomenon. The population of interest is freight forwarders from the Dubai International Airport, United Arab Emirates. The Middle East represents 18 percent of the world's air cargo volume and …

The Mental Health Screening of Student Athletes by NCAA Athletic Departments
This study explored NCAA athletic departments' mental health screening practices, including the mental health concerns assessed for by the mental health screening, personnel responsible for administering and reviewing screeners, and resources available for athletes identified as "at risk." Participants were athletic department staff who had knowledge of their school's mental health screening processes. Frequencies and chi-square analyses were used to assess trends across divisional levels (DI vs. DII/DIII). Analyses show that significantly more DI than DII/DDIII institutions have a formal mental health screening program. Institutions' coverage of mental health topics in their screening did not vary significantly by Divisional level, with one exception: a larger percentage of DI institutions assessed whether student athletes had worked with a mental health practitioner than DII/DIII schools. DII/III were significantly more likely to have athletic trainers both administer and review mental health screeners and DI institutions were significantly more likely to have a sport psychologist employed within their athletic department than. DI schools were significantly more likely to have had a student athlete attempt suicide and participate in inpatient treatment than DII/III schools. Implications of the findings, limitations, and future directions are discussed.

Sport Transition and Current Preretirement Planning Practices among NCAA Institutions
Research has shown that when athletes engage in preretirement planning and address various factors associated with leaving sport (e.g., voluntariness of retirement, shifting identity away from that of an athlete, preretirement planning, personal development, career development, social support), they had significantly better cognitive, emotional, and behavioral adaptation to life after sport. The NCAA is one of the largest sport institutions in the world and they provide limited guidelines to member institutions regarding preparing student-athletes for retirement from sport, and as a result, different schools are developing their own programs. This study explored what NCAA athletic departments do to prepare their student-athletes for their graduation and transition out of sport. Participants were athletic department administrators, and they completed a survey that assessed for current preretirement planning practices and available campus resources for student-athletes who are transitioning out of sport. I used frequencies, t-tests, and chi-square analyses to assess trends across divisional levels (DI vs. DII/DIII). Analyses show that significantly more DI than DII/DDIII institutions have preretirement planning programs. Additionally, there is no significant difference between the topics that are covered across divisional level. The degree to which participants agreed that athletic departments have an ethical/moral responsibility and their perception of who …
