Exploring the Relationships Between Faculty Beliefs and Technology Preferences (open access)

Exploring the Relationships Between Faculty Beliefs and Technology Preferences

All too often faculty are asked to implement technology into their teaching without the knowledge necessary to use the technology effectively. Due to the evolution of technology in everyday settings, students have come to expect to be engaged through technological means. This often creates undue stress on faculty members. The purpose of this study is to investigate technology integration by exploring the relationships between a faculty member’s technology preferences and educational beliefs. Through a mixed method, this study attempts to address the question of why faculty use the types of technology they do. More importantly, this study investigates if a faculty member’s educational beliefs have any influence on the technology they choose to use. Thirty-two medical, clinical, and healthcare faculty members participated in the study. They responded to a Teaching Perspectives Inventory (TPI) survey and a Technology Preferences survey with open-ended questions. Data analysis revealed multiple statistically significant findings between different beliefs and different types of technology. The results indicated that personal epistemic beliefs influence the types of technology faculty use. The technology choices faculty make are largely related to tools they are comfortable with and ones they believe effectively fit their teaching materials. The study also found statistically significant …

An Assessment of Uncommon Titanium Binary Systems: Ti-Zn, Ti-Cu, and  Ti-Sb (open access)

An Assessment of Uncommon Titanium Binary Systems: Ti-Zn, Ti-Cu, and Ti-Sb

The current study focuses on phase stability and evolution in the titanium-zinc titanium-copper and titanium-antimony systems. The study utilized the Laser Engineering Net Shaping (LENS™) processing technique to deposit compositionally graded samples of three binary system in order to allow the assessment of phase stability and evolution as a function of composition and temperature the material is subjected to. Through LENS™ processing it was possible to create graded samples from Ti-xSb (up to 13wt%) and Ti-xCu (up to 16wt%). The LENS™ deposited gradient were solutionized, and step quenched to specific aging temperature, and the resulting microstructures and phase were characterized utilizing XRD, EDS, SEM, FIB and TEM. The Ti-Zn system proved incapable of being LENS™ deposited due to the low vaporization temperature of Zn; however, a novel processing approach was developed to drip liquid Zn onto Ti powder at temperatures above β transus temperature of Ti (882 ◦C) and below the vaporization temperature of Zn (907 ◦C). The product of this processing technique was characterized in a similar way as the graded LENS™ depositions. From measurements performed on Ti-Sb it seems that Sb could be a potential α stabilizer in Ti due to the presence of a mostly homogeneous α …

Exploring the College Pathways of Asian American Community College Students and the Model Minority Myth (open access)

Exploring the College Pathways of Asian American Community College Students and the Model Minority Myth

Contrary to the model minority myth that portrays Asian Americans as academic all-stars over-represented in elite four-year institutions, half of all Asian American college students do in fact attend community colleges, and many experience myriad challenges. This exploratory study investigated the community college pathways of Asian American community college students, the role of family and culture in shaping expectations for higher education, and participants’ perceptions of the model minority myth and the degree to which this myth influenced their college experiences. Institutional practices and policies, or lack thereof, that support the success of this highly diverse population were also studied. Purposeful sampling was used to gather a sample of 28 students, who self-identified as Asian American and attended one of the three largest community college districts located in North Texas. The sample included 16 males and 12 females, whose ages ranged from 18 to 49 years old, with a mean age of 24. Data collection involved a demographic questionnaire and semi-structured individual interviews. The participants represented 13 different ethnicities, and nine were members of more than one ethnic or racial group. Ten participants were foreign-born citizens, and all of the participants had at least one foreign-born parent. Qualitative data provided …

Sleep Duration, Sleep Insufficiency, and Carotid Intima-Media Thickness (open access)

Sleep Duration, Sleep Insufficiency, and Carotid Intima-Media Thickness

Cardiovascular disease is the leading cause of death in the United States. Chronic short sleep duration is also a significant public health problem and has been linked to several markers and outcomes of cardiovascular disease. To date, inconsistency of assessments of sleep duration and insufficiency, use of covariates, and cardiovascular disease measurement across studies limits strong conclusions about the relationship between sleep duration, sleep insufficiency, and cardiovascular disease. The current study examined the association between sleep duration, sleep insufficiency, and a marker of preclinical coronary heart disease (i.e., carotid intima-media thickness) in a community sample using a cross-sectional design. Some evidence for a relationship between sleep duration and cIMT was found, with longer sleep duration predicting higher cIMT in some segments. Additionally, the interaction between sleep duration and sleep insufficiency was significant. However, neither of these effects were significant after adjusting for age and in some cases race/ethnicity, suggesting demographics may explain this association. Actigraphy and sleep diary duration assessments demonstrated significantly different correlations with cIMT in some segments, suggesting the nature of the assessment method may impact the strength or direction of the relationship between sleep duration and cIMT. Limitations and future directions are discussed.

Co-Creating Value in Video Games: The Impact of Gender Identity and Motivations on Video Game Engagement and Purchase Intentions

When games were first developed for in-home use, they were primarily targeted almost exclusively at children and males. However, today’s marketplace manifests a more diverse population plays Internet-enabled games that can be played virtually anywhere. The average gamer is now 30 years old. Many gamers, obviously, are much older. Yet more strikingly, and more germane to this study’s purpose, 47% of the U.S. gamer population is female, as compared to 40% in 2010. Despite these trends the gaming industry remains a male-dominated culture. The marketer’s job is to facilitate game engagement and to motivate gamers to play. The notion of “engagement” is not new in business. The term was developed in the last decade. Many studies were devoted to understand, explain, and define the term. It suggests that within interactive, dynamic business environments, consumer engagement (CE) represents a strategic position that companies can use to enhance their sales growth, competitive advantage, and profitability. Moreover, there are three levels of engagement in any experiential consumption (i.e., playing video game): presence, flow, and psychological absorption. The findings of this study affirm that consumer engagement, including presence, flow and psychological absorption are explanatory factors that impact gamer’s purchase intentions.

Associations Between Physical Fitness and Academic Achievement: A Meditational Analysis (open access)

Associations Between Physical Fitness and Academic Achievement: A Meditational Analysis

Research has illustrated the interrelatedness of childhood physical fitness and psychological wellbeing, psychological wellbeing and academic achievement, as well as physical fitness and academic achievement. In this study, we proposed that psychological wellbeing (self-esteem and depression) serves as a mediator between physical fitness and academic achievement during adolescence. In a sample of middle school children (N = 1,530), significant correlations were found between all three variables (p.0001). A hierarchical regression analysis was performed to assess the associations between physical fitness, psychological wellbeing, and academic achievement. The regression analysis reported a significant partial mediation effect. The results of this study supported the proposed hypotheses, including a mechanism of psychological wellbeing partially mediating the relationship between physical fitness and academic achievement. The findings of this study support the importance of encouraging activities to promote both physical fitness and psychological wellbeing in schools.

Funds of Knowledge and Early Literacy: A Case Study

When teachers are charged with educating students that are racially, culturally, or economically different from them, they may have little information on the culture and type of family involvement of their students. This lack of information contributes to perceptions of working-class families as socially disorganized and intellectually deficient. However, research embodying the theoretical framework funds of knowledge (FoK) attempts to counter deficient models through its assertion that all families possess extensive bodies of knowledge that have developed through social, historical, political, and economic contexts. The primary purpose of this study was to carefully examine Hispanic parents’ support of young children’s early literacy development in the home. The knowledge gleaned from an initial study of home support, by spending time in the home of a Hispanic family provided an avenue for action research in the classroom. A second purpose was to determine if the introduction of FoK ways of learning, when applied in the classroom, had an effect on early literacy skills. In addition, I maintained a journal that chronicled my experiences and led to an autoethnographic study of myself as a transforming white, female, prekindergarten teacher. The results indicated that the family possessed extensive FoK developed through historical, cultural, educational, …

The Descriptive Paleontology and Applied Ichthyoarchaeology of the Ponsipa Fauna (open access)

The Descriptive Paleontology and Applied Ichthyoarchaeology of the Ponsipa Fauna

The archaeology of the Northern Rio Grande region of New Mexico has recently received an increased amount scholarly attention. In particular, understanding past trends in demographics, agricultural productivity, violence, and social networks have been primary goals of archaeological research. Understanding patterns in animal exploitation has, however, received far less attention due to a small yet growing regional zooarchaeological database. Through the identification of animal remains from a site called Ponsipa (occupied ca. A.D. 1300 to 1600), this thesis adds one large dataset to this growing database. In addition, this thesis expands on the pre-impoundment distribution of an endangered native freshwater fish species in the state of New Mexico called the blue sucker (Cycleptus elongatus). The blue sucker is a unique fish that is currently experiencing range reduction across all of its known North American distribution due to anthropogenic habitat fragmentation and degradation. Skeletal remains that were identified from Ponsipa represent the farthest known northern record of its occurrence in the state of New Mexico and highlight the extent of range restriction of the species in the area. The data concerning the historical biogeography of the blue sucker from Ponsipa have implications for the effective conservation and restoration of blue sucker …

Amarillo Globe-News: How Did Gene Howe and the Globe-News Help Guide Amarillo, Texas through the Dust Bowl and Great Depression?

For many years newspapers were locally owned by editors and publishers. However, today many are run by corporations from out of state. As a result, many communities have lost the personal relationship between the family owned publication and the community. Gene Howe, who served as editor, publisher and columnist of the Amarillo Globe-News from 1926 until his death in 1952, believed the community was where the focus should be and the newspaper should do all that it can to help their readers. Despite the fact that Howe was not born in Amarillo, Texas, his passion and love for the city and its inhabitants compensated for it. During the Dust Bowl and Great Depression Howe and the Globe-News helped Amarillo survive the dust and economic storms that blew through the Texas Panhandle, an area that has not been written as much as other parts of Texas. Through his “Tactless Texan” column, which served as a pulpit to the community, to the various contests and promotions the newspaper sprang up, including the creation of Mother in Law Day, Gene Howe gave the newspaper another dimension little has been studied about, the role of the editor and publisher in guiding a community through …

A Construct Validity Analysis of the Work Perceptions Profile Data (open access)

A Construct Validity Analysis of the Work Perceptions Profile Data

As work environments become more complex and demanding, organizations are becoming more interested in measuring the impact of their human resource development programs and initiatives. With this increased attention on data and measurement, human resource professionals have been encouraged to utilize data collection and data analysis techniques to make more objective and rationale human capital decisions and to verify business impact. As a result, the human resource profession has seen a significant increase in the use of surveys to measure anything from training effectiveness to the efficacy of recruitment procedures. The increase in the use of survey instruments requires that more focused attention is placed on the reliability and validity of data from any instrument used to make important human resource and business decisions. One instrument that is currently being used to measure career plateaus and job fit is the Work Perceptions Profile. The purpose of this research study was to conduct a construct validity analysis of the Work Perceptions Profile data and to determine the factor structure of data from its items. The data in this analysis supported a two-factor model structure with the first factor measuring Work Characteristics and a second factor measuring Performance. The results of this …

First Movement of the Beethoven Third Piano Concerto: An Argument for the Alkan Cadenza (open access)

First Movement of the Beethoven Third Piano Concerto: An Argument for the Alkan Cadenza

The goal of this dissertation is not only to introduce the unique cadenza by Alkan but also to offer an argument from the performer’s point of view, for why Alkan’s cadenza should be considered when there exists a cadenza by Beethoven himself, not to mention those by a number of other composers, both contemporaries of Beethoven and later. Information in reference to the brief history of the cadenza and the pianoforte in the time of Mozart and Beethoven is presented in Chapter 2. A brief bibliography about Alkan is presented in Chapter 3. Chapter 4 describes not only the cadenza in the era of Alkan, but also a comparison which is presented between Beethoven and Alkan's cadenzas. Examples of the keyboard range, dynamic contrast, use of pedal and alternating notes or octaves, and creative quote are presented in Chapter 4. In conclusion, the revival of Alkan's cadenza is mentioned, and the author's hope to promote the Alkan's cadenza is presented in Chapter 5.

Plebiscites (open access)

Plebiscites

This study investigates factors that can influence leaders to use plebiscites to settle territorial claims. A quick survey of the plebiscite literature shows that the method has been extensively mentioned in the legal, historical, and philosophical fields (mostly through case studies) but less so in political science. This thesis is the first attempt, to my knowledge, to quantitatively investigate the different factors that can influence a leader to use a plebiscite. Using the latest version of the ICOW dataset, I test political and economic theories to try to explain the variation in the decision outcome. This study includes the following variables: identity ties, economic strength, an interaction between identity ties and economic strength, internal constraints (regime type and violent interaction), and external constraints (membership to international organizations). The results suggest that identity ties offer the strongest explanation as to why leaders settle a territorial claim with a plebiscite. Plebiscites have been rarely used to settle territorial claims, but when used they tend to settle cases permanently. This thesis serves as an attempt to revive a method that while difficult to agree upon, can be successful in resolving territorial claims permanently, and more importantly peacefully.

An Analysis of Du cristal…à la fumée by Kaija Saariaho and Axiom Unearthed, Original Composition (open access)

An Analysis of Du cristal…à la fumée by Kaija Saariaho and Axiom Unearthed, Original Composition

Beginning in the 1970s, and aided by the advancement and an increased prevalence of computers, spectral music emerged as an important development in twentieth century music. Spectral composers, as exemplified by Gérard Grisey and Tristan Murail, took the harmonic spectra of sounds as the fundamental materials of composition. The resulting music placed an emphasis on texture and gradually evolving forms. The generation of composers immediately following the spectralists assimilated their techniques into distinct and varying styles. Finnish composer Kaija Saariaho uses spectral techniques to create an aesthetic that generates form and progression from a sound/noise axis. In her piece Du cristal…à la fumée, a number of pendulum and half-pendulum gestures build up texture and form. The accompanying original composition Axiom Unearthed employs similar pendulum gestures and uses spectral techniques to generate melody and harmony in an aesthetic divergent from traditional spectral pieces.

Alternative Certification Teaching Programs in Texas: A Historical Analysis (open access)

Alternative Certification Teaching Programs in Texas: A Historical Analysis

Before 1984, nearly 975 of teachers entered the teaching profession after graduating from a traditional university-based program. However, beginning in the mid-1980s, alternative routes leading to teacher certification began to emerge in the United States. As of 2010, nearly one-third of all new teachers graduated from an alternative preparation program. As alternative certification (AC) routes approach 30 years since establishment, programs continue to evolve and increase in enrollment. This study focused on the changes that have come about in the maturation of alternative certification programs in Texas since legislation was passed in 1985. The purpose of the study was to delineate the evolution of AC programs using a historical approach, the study used both primary and secondary resources as research tools and employed the use of eight interviews and the literature review for the collection of data. The prediction of future teacher shortages, the need for diversity in the profession the political view to privatize education, and economic recessions were all motivating factors for establishing alternative teacher programs. In the beginning, graduation from AC programs were perceived as not authentic teachers and not as prepared for teaching as graduates from traditional programs. AC programs have become a legitimate and viable …

The Devil and the Details: Negotiating Virtuosity, Agency, and Authenticity in Karlheinz Stockhausen’s Kathinkas Gesang als Luzifers Requiem for Solo Flute

Karlheinz Stockhausen’s Kathinkas Gesang als Luzifers Requiem presents mental, physical, and musical challenges that go beyond the usual expectations of an instrumentalist, extending and redefining the traditional idea of virtuosity. Using firsthand performance experience, score and recording study, and flutist interviews, this document explores the effects of some of these heightened demands and argues that the particular performance situation presented by Kathinkas Gesang brings up critical questions about the performer’s role, the nature of performance and of the musical work, and the existence of an authoritatively “authentic” interpretation. Employing an expanded definition of virtuosity that includes interpretation and encompasses both choices and actions, the document discusses the extensions of virtuosity into two main areas: first, memory; and second, staging and movement, covering both practical suggestions and larger implications. Finally, it examines how the performer’s negotiation of these challenges relates to questions about authenticity and agency. Performance is defined here as a creative and collaborative act, not attempting to duplicate previous performances or recordings, but rather to give the best realization of the piece possible in the given circumstances, according to the individual’s interpretation of the score’s directions. There is no single “authentic” interpretation, but rather a rich multiplicity of possibilities, …

Improving Processing Efficiency for Forensic DNA Samples (open access)

Improving Processing Efficiency for Forensic DNA Samples

The goal of this project was to reduce processing time for forensic DNA testing without incurring significant added costs and/or the need for new instrumentation, while still generating high quality profiles. This was accomplished by: 1) extraction normalization using the ChargeSwitch® Forensic DNA Purification Kit such that a small range of DNA concentrations was consistently obtained, eliminating the need for sample quantification and dilution; 2) developing fast PCR protocols for STR primer sets using shorter amplification methods, low volume reactions and non-fast thermal cyclers; and 3) developing a quicker 3130xl Genetic Analyzer detection method using an alternative polymer/array length combination. Extraction normalization was achieved through a reduction in bead quantity, thereby forcing an increase in bead binding efficiency. Four products (AmpliTaq Gold® Fast PCR Master Mix, KAPA2G™ Fast Multiplex PCR Kit, SpeedSTAR™ HS DNA Polymerase and Type-it Microsatellite PCR Kit) were evaluated for low volume (3μl) fast PCR on a 384-well Veriti® thermal cycler with the Identifiler primer set. KAPA2G™ was selected for 3μl fast PCR protocols using PowerPlex 16 HS and Identifiler Plus primer sets (42-51min), as well as 5μl and 6μl Identifiler fast reactions on a 9700 thermal cycler (51-60min).

Refining the Definition and Detection of Response Styles: An Initial Examination of Defensiveness and Feigning on the Personality Inventory for DSM-5 (open access)

Refining the Definition and Detection of Response Styles: An Initial Examination of Defensiveness and Feigning on the Personality Inventory for DSM-5

The fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM 5) presents an alternate model for personality disorders, blending categorical and dimensional assessment into a hybrid diagnostic procedure. Released concurrently, the Personality Inventory for DSM 5 (PID 5) measures the five domains and 25 facets that comprise the trait components of this hybrid model. However, the PID 5 currently lacks validity indicators to capture intentionally distorted responding. The current study investigated the susceptibility of the PID 5 to defensiveness and feigning among a large sample of undergraduate students. First, a detailed desirability analysis (N = 465) was conducted of the PID 5 items and response options. Responses from the study were used to create three desirability based validity scales. Next, in a between-subjects simulation design (N = 128), the effects of faking were explored at domain and facet levels. As a result, two symptom based validity scales were created. In a separate validation sample (N = 134), the five newly created validity scales were compared with the Paulhus Deception Scales for capturing both defensiveness and feigning. All five scales were evaluated for ruling out faking (i.e., identifying likely genuine respondents) and ruling in either defensiveness or feigning. …

Through an Open Window

The poems in this collection are elegiac; celebrations of losses and failures, tributes to the daily doldrums that are at the center of human experience. They threaten to expose the uncertainty that exists and refuses to exist in our everyday lives. They explore the otherness associated with the individual and often turn to the universal formulas of music and physics to make order of the world around them. Often times the Speaker finds that the seeming chaos manifests within her already orderly life, the daily routines of work and family. Poetic magic, so to speak, weds this ordered chaos to the laws of nature and its routines, especially birds, which makes a recurrent appearance throughout the manuscript.

Transfer From a UTeach Replication Site to the Classroom: A Study of First and Second Year Instructional Practices

Concerns based adoption model (CBAM) instruments were used to examine instructional practices of six graduates from a highly stylized, inquiry-based secondary math and science preparation program. Teachers were in the first or second years of teaching mathematics in six different secondary settings, ranging from poverty to wealthy schools. CBAM assumptions were tested. The primary assumption about concerns was that new teachers’ highest concerns would be within the self and task dimensions. According to Hall and Hord, it was assumed that the levels of use are typically in the orientation and preparation stages as a new teacher begins to implement an innovation, in the case of this study, inquiry-based instruction. All three instruments of the CBAM model were used for data collection and included: the Survey of Concerns Questionnaire, Innovation Components Configuration Map, and Levels of Use matrix. Teachers were observed, interviewed, and surveyed, three times each, across a five-month period. The findings from this study showed that the teachers had similar concerns and levels of use, which supported the assumptions outlined by the CBAM principles. Across the six teachers, the self and task concerns were high, aligning with the assumptions. However, unrelated and impact dimensions were noted, in opposition to …

The Influence of Psychological Momentum on Basketball Shooting Performance (open access)

The Influence of Psychological Momentum on Basketball Shooting Performance

The purpose of this research was to examine the influence of fictitious scoring updates on psychological momentum (PM) and athletic performance in a competitive basketball setting. The participants included in this study were 50 male undergraduate students who reported having played basketball previously and qualified by being able to make more than 24% (12 out of 50) of their 3-point shots in a pre-trial session. Participants were told that they were competing in a 50 shot, 3-point shooting competition against another individual, equal in ability. After every 10 shots, participants were given a fabricated score update and answered four questions used to measure PM. Results showed that the fictitious score updates significantly (p < .01) influenced participants’ PM scores, where those who were told they led had higher PM scores than those who were told they trailed. As for shooting performance, no significant differences (p = .76) were found between positive and negative PM states for participants who reported experiencing both during the competition. Together, these findings suggest that manufactured score updates can influence PM, but resultant performance differences may not exist. Results of this study lend support to the notion that PM is experienced by athletes. However, when examining …

Investigating Teachers’ Backgrounds and Instructional Practices to Improve Mathematics Teacher Training Programs

In recent years, considerable concern has arisen over cross-national student’s math achievement. A number of studies focusing on eighth grade student’s math achievement have been published. However, the most important role we should consider is not only students, but also teachers. A good teaching training program could help teachers improve their teaching expertise and student’s math achievement. Moreover, most studies only focused on explained predictions of the effect between potential factors. Therefore, the purpose of this study is to implement a hierarchical linear model and cluster analysis techniques to re-examine the Trends in International Mathematics and Science Study (TIMSS) 2011 among eighth grade students in the United States (U.S.), South Korea, Singapore, and Taiwan. These techniques were applied to provide a teacher characteristics and student math achievement model and identify a new institutional typology based on the pattern of teacher characteristic types and countries. Based on these patterns and model, this study presented the findings, as well as suggestions for improving educational policies and teaching training program in, South Korea, Singapore, Taiwan, and the U.S.

To Weigh or Not to Weigh? Relation to Disordered Eating Attitudes and Behaviors Amongst Female Collegiate Athletes (open access)

To Weigh or Not to Weigh? Relation to Disordered Eating Attitudes and Behaviors Amongst Female Collegiate Athletes

Collegiate and elite female athletes have been identified as a subpopulation at heightened risk for disordered eating and pathogenic weight management practices. It was hypothesized that this increases risk may be related to sport specific pressures (such as team conducted weigh-ins), or the use and frequency of self-weighing. It appears that mandatory, team conducted weigh-ins are not salient to female athletes in regards to experiencing internalization, body image concerns, dietary restraint, negative affect, and bulimic symptomatology. Results, however, indicate that frequency of engagement in self-weighing may be influential in the engagement of disordered eating symptoms. Specifically, athletes who weighed themselves three or more times per week reported significantly more internalization of general societal ideals and athletic body ideals. For body image concerns, athletes who weighed three or more times per week reported being more concerned with their body size/shape than all others. With respect to dietary behaviors, athletes who weighed themselves three or more times per week reported engaging in significantly more caloric restriction than did those who weighed less frequently. For negative affect, the athletes who weighed themselves three or more times per week reported significantly higher levels of both anger and guilt. Finally for bulimic symptomatology, athletes who …

Polyphonic Harmony in Three of Ferruccio Busoni’s Orchestral Elegies (open access)

Polyphonic Harmony in Three of Ferruccio Busoni’s Orchestral Elegies

This dissertation focuses on three of Busoni’s late orchestral works known as “orchestral elegies”: Berceuse élégiaque (Elegie no. 1, 1909), Gesang vom Reigen der Geister (Elegie no. 4, 1915), and Sarabande (Elegie no. 5, 1918-19). The study seeks to provide a better understanding of Busoni’s late style as a crucial bridge from late nineteenth-century chromaticism in the works of Liszt, Wagner, and others to the post-tonal languages of the twentieth century. At the heart of this study lies a particular concept that forms the basis of many characteristic features of Busoni’s late style, namely the concept of polyphonic harmony, or harmony as a cumulative result of independent melodic lines. This concept is also related to a technique of orchestration in which the collective harmony is sounded in such a way that the individual voices are distinct. In the highly personal tonal language of Busoni’s late works, passages often consist of a web of motives weaved throughout the voices at the surface level of the music. Linear analysis provides a means of unravelling the dense fabric of voices and illustrating the underlying harmonic progressions, which most often consist of parallel, primarily semitonal, progressions of tertian sonorities. Chapter 1 provides a backdrop …
