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 …

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 …

An Introduction to Contemporary Violin Techniques: A Practical Guide with Exercises for Students and Teachers
Violin repertoire composed in the late twentieth and early twenty-first centuries placed new demands on performers. While numerous pedagogues have written etudes and treatises analyzing traditional techniques, far fewer have thoroughly examined contemporary techniques. Many of the existing etudes and exercises inspired by contemporary violin repertoire are of a very high difficulty level and may seem unapproachable to students with little to no experience performing the music of recent decades. As a result, many violin students are unacquainted with the language of new music. This dissertation is intended to help fill a gap in the pedagogical literature by serving as a resource that familiarizes advanced students with the notation and proper execution of the non-traditional techniques commonly found in contemporary violin music. This document includes a survey of violin repertoire written since 1970, an analysis of the non-traditional techniques used most often in the works examined, methods for approaching specific technical problems that arise in them, and nine etudes originally composed by this author. The etudes focus on nine contemporary techniques, ranging from contact point variations to changing subdivisions, and are intended for study by advanced violinists interested in performing contemporary music.

François Couperin's Neuvième Concert, "Ritratto Dell' Amore": A Performance Guide and Edition for Flute and Keyboard
François Couperin (1668-1733) was one of the earliest French Baroque composers to merge the Italian style into the French tradition. He had great influence on the development of French Baroque music from the end of the seventeenth century until his death. Couperin's four Concerts Royaux and the ten Concerts Nouveaux (published in 1722 and 1724) were written for the enjoyment of Louis XIV. Those suites were popular in the court before they were published, as they were requested to be performed every Sunday during the years 1714 and 1715 to give pleasure to the king. Rittrato dell'amore is the ninth suite out of the fourteen suites. The purpose of this study is to provide a performance guide and a practical edition of François Couperin's Neuvième Concert Ritratto dell' amore. It also contrasts Italian style and French tradition in the Baroque period, and how Couperin blended both styles together in his Neuvième Concert. In addition, this dissertation summarizes the general principles of Baroque performance practice that one may encounter in Neuviéme Concert, including notes inégales (unequal notes), ornamentation, over-dotting, and other issues. It is especially important for one to understand the performance style of French Baroque music in order to perform …

Crystallization and Lithium Ion Diffusion Mechanism in the Lithium-Aluminum-Germanium-Phosphate Glass-Ceramic Solid Electrolytes
NASCION-type lithium-aluminum-germanium-phosphate (LAGP) glass-ceramic is one of the most promising solid electrolyte (SEs) material for the next generation Li-ion battery. Based on the crystallization of glass-ceramic material, the two-step heat treatment was designed to control the crystallization of Li-ion conducting crystal in the glass matrix. The results show that the LAGP crystal is preferred to internally crystalize, Tg + 60%∆T is the nucleation temperature that provides the highest ion conductivity. The compositional investigation also found that, pure LAGP crystal phase can be synthesized by lowering the amount of GeO2. To fill gap of atomic structure in LAGP glass-ceramic, molecular dynamic (MD) simulation was used to build the crystal, glass, and interfacial structure LAGP. The aliovalent ion substitution induced an simultaneously redistribution of Li to the 36f interstitial site, and the rapid cooperative motion between the Li-ions at 36f can drop the activation energy of LAGP crystal by decreasing the relaxation energy; furthermore, an energy model was built based on the time-based analysis of Li-ion diffusion to articulate the behavior. The glass and interfacial structure show and accumulation of AlO4, GeO4 and Li at the interface, which explains the Li-trapping on the intergranular glass phase. An in-situ synchrotron X-ray study found …

Viability Study of Nylon-12 Carbon Fiber Filaments for Use in the Construction of a Powered Lower Body Exoskeleton via Fused Deposition Modeling by Means of Computer Simulation
Members of the elderly population is disproportionately prone to experiencing mobility impairment due to their aging bodies and as a result have frail bodies that are at a higher risk of grave injury due to falling. In order to combat this assistive mobility devices such as exoskeletons have been developed to help patients enhance their range of motion. With additive manufacturing techniques, such as fused deposition modeling (FDM), becoming a more mainstream form of design, the inclusion of lightweight polymers such as nylon 12 as primary construction materials for these devices has increased. In this thesis computer aided design (CAD) software was used to design a prototype lower body exoskeleton and simulation software was used to give the device the characteristics of Stratasys' nylon 12 carbon fiber FDM material to verify it if could be used as the primary construction material for this device when extruded from a FDM printer on either the XZ or ZX printing plane. From the simulations it was found that the material printed along the XZ plane could create a device that could withstand the weight of an average elderly male patient (200 lbs.) as well as the 35 lbs. of force applied to the …

Campus Leader and Teacher Perceptions of Campus Administrator Actions in Support of Core-Content Professional Learning Communities
The implementation of professional learning communities (PLCs) has led to systemwide reform within school districts and campuses regarding how campus leaders support the teachers' collaborative work and continued professional learning. Current research emphasizes the importance of campus administrators cultivating an environment where PLCs can flourish and ensuring that PLC teams have the resources to work effectively. However, campus administrators simply putting these supports in place does not make them effective. This study sought to explore campus leader and teacher perceptions of administrator actions that support PLCs for teachers in core-content subjects at two suburban north Texas high schools. An explanatory sequential mixed methods research design was utilized, and three data collections tools were used: an electronic survey, interviews with campus administrators and teachers, and the analysis of campus and PLC artifacts. Survey data indicated that participating teachers had an overall positive perception of the current campus practices which support PLC teams. Teacher interview data revealed that teachers preferred that campus administrators take a neutral role in PLC team meetings, that administrators ensure PLC teams are meeting the established campus PLC expectations, and that administrators observe the team, listen, and ask questions to help the team. Campus administrators viewed their actions …

The Strategic Use of Religion in a Secular State: The Impact of Religious Organizations on Japanese Politics
How do religions and nationalism interact in secular democracies? With its history of nationalism based on religious ideologies, and the subsequent forced separation of state and religion, Japan provides a valuable case to examine how religion and nationalism interact and affect the politics of a secular state. The purpose of this dissertation is to understand and synthesize the divide within the literature regarding the idea that Shinto is fundamentally nationalist in nature. Due to Shinto's historical ties to Japanese nationalism, it is clear that religion and nationalism played a role in Japanese politics in the past. However, with Japan's transition to democracy and the constitutional provision of the separation between religion and state, religion's effect on nationalism in Japan has become blurred contemporarily. In order to explore these relationships between Shinto, nationalism, and Japanese politics, I investigate how political groups and religious organizations influence nationalist sentiment in political institutions and public opinion in Japan using the Japanese Value Orientations survey and an original dataset. I find that even though the evidence is mounting against the accuracy around the idea of State Shinto and the fundamentally nationalist nature of Shinto, the narrative persists. The existence of nationalist circles perpetuates these narratives, …

Studies on Intrinsic Coagulation Pathway of Zebrafish
In the past couple of decades, the zebrafish has been widely used to study hemostatic disorders. In this study, we generated a CRISPR/Cas9 mediated zebrafish mutant that contains a 55-nucleotide insertion in exon 29 of the von Willebrand factor (vwf) gene. The mutants had impaired ristocetin-mediated agglutination of whole blood, prolonged PTT and more bleeding in the lateral incision compared to wild-type fish. The bleeding phenotype observed here is similar to the phenotype observed in vwf knockout mice and patients with von Willebrand disease (VWD). The mutant model developed here can thus be used for exploring the role of Vwf in angiogenesis and for developing gene therapy. The deficiency of VWF causes VWD and the etiology remains unknown in 30% of Type 1 VWD cases. Previous studies have identified that the ABO blood group and ST3GAL4 (glycosyltransferases) are involved in the regulation of VWF levels. Since VWF is heavily glycosylated, we hypothesized that other glycosyltransferases may also be involved in regulating VWF. We performed a knockdown screen of 234 glycosyltransferase genes and identified 14 genes that altered Vwf levels. The sequencing of these genes in Type 1 VWD patients could help identify novel mutations to decipher the molecular basis for …

Development and Application of Novel Computer Vision and Machine Learning Techniques
The following thesis proposes solutions to problems in two main areas of focus, computer vision and machine learning. Chapter 2 utilizes traditional computer vision methods implemented in a novel manner to successfully identify overlays contained in broadcast footage. The remaining chapters explore machine learning algorithms and apply them in various manners to big data, multi-channel image data, and ECG data. L1 and L2 principal component analysis (PCA) algorithms are implemented and tested against each other in Python, providing a metric for future implementations. Selected algorithms from this set are then applied in conjunction with other methods to solve three distinct problems. The first problem is that of big data error detection, where PCA is effectively paired with statistical signal processing methods to create a weighted controlled algorithm. Problem 2 is an implementation of image fusion built to detect and remove noise from multispectral satellite imagery, that performs at a high level. The final problem examines ECG medical data classification. PCA is integrated into a neural network solution that achieves a small performance degradation while requiring less then 20% of the full data size.
