With the Earth in Mind: Ecological Grief in the Contemporary American Novel

With the Earth in Mind: Ecological Grief in the Contemporary American Novel

Access: Use of this item is restricted to the UNT Community.
Date: 2016-5
Creator: Reis, Ashley Elaine
Description: "With the Earth in Mind" responds to some of the most cutting-edge research in the field of ecocriticism, which centers on ecological loss and the grief that ensues. Ecocritics argue that ecological objects of loss abound--for instance, species are disappearing and landscapes are becoming increasingly compromised--and yet, such loss is often deemed "ungrievable." While humans regularly grieve human losses, we understand very little about how to genuinely grieve the loss of nonhuman being, natural environments, and ecological processes. My dissertation calls attention to our society's tendency to participate in superficial nature-nostalgia, rather than active and engaged environmental mourning, and ultimately activism. Herein, I investigate how an array of postwar and contemporary American novels represent a complex relationship between environmental degradation and mental illness. Literature, I suggest, is crucial to investigations of this problem because it can reveal the human consequences of ecological loss in a way that is unavailable to political, philosophical, scientific, and even psychological discourse.

An Analysis of Educational Technology Publications:  Who, What and Where in the Last 20 Years

An Analysis of Educational Technology Publications: Who, What and Where in the Last 20 Years

Date: 2016-5
Creator: Natividad Beltran Del Rio, Gloria Ofelia
Description: This exploratory and descriptive study examines research articles published in ten of the top journals in the broad area of educational technology during the last 20 years: 1) Educational Technology Research and Development (ETR&D); 2) Instructional Science; 3) Journal of the Learning Sciences; 4) TechTrends; 5) Educational Technology: The Magazine for Managers of Change in Education; 6) Journal of Educational Technology & Society; 7) Computers and Education; 8) British Journal of Educational Technology (BJET); 9) Journal of Educational Computing Research; and 10) Journal of Research on Technology in Education. To discover research trends in the articles published from 1995-2014, abstracts from all contributing articles published in those ten prominent journals were analyzed to extract a latent semantic space of broad research areas, top authors, and top-cited publications. Concepts that have emerged, grown, or diminished in the field were noted in order to identify the most dominant in the last two decades; and the most frequent contributors to each journal as well as those who contributed to more than one of the journals studied were identified.

Creator: Wu, Min
Description: Two-dimensional (2D) transition metal dichalcogenides (TMDs) show great potential for the future electronics, optoelectronics and energy applications. But, the studies unveiling their interactions with the host substrates are sparse and limits their practical use for real device applications. We report the facile nano-scratch method to determine the adhesion energy of the wafer scale MoS2 atomic layers attached to the SiO2/Si and sapphire substrates. The practical adhesion energy of monolayer MoS2 on the SiO2/Si substrate is 7.78 J/m2. The practical adhesion energy was found to be an increasing function of the MoS2 thickness. Unlike SiO2/Si substrates, MoS2 films grown on the sapphire possess higher bonding energy, which is attributed to the defect-free growth and less number of grain boundaries, as well as less stress and strain stored at the interface owing to the similarity of Thermal Expansion Coefficient (TEC) between MoS2 films and sapphire substrate. Furthermore, we calculated the surface free energy of 2D MoS2 by the facile contact angle measurements and Neumann model fitting. A surface free energy ~85.3 mJ/m2 in few layers thick MoS2 manifests the hydrophilic nature of 2D MoS2. The high surface energy of MoS2 helps explain the good bonding strength at MoS2/substrate interface. This simple adhesion ...

The Recorded Legacy of Enrico Caruso and its Influence on the Italian Vocal Style

The Recorded Legacy of Enrico Caruso and its Influence on the Italian Vocal Style

Date: 2016-5
Creator: Garst, John Dee
Description: This dissertation presents evidence for the influence which tenor Enrico Caruso had on the Italian Vocal Tradition. This impact was clearly boosted by the revolution realized in the fledgling recording industry, and the recordable disc. In the years of 1902-1920 gramophones became commonplace, and collecting recordings became an interest for many. This new technology required specialized skills, and was especially suited to certain qualities of voice. Caruso enjoyed immense success in this medium, in recording over 250 records. Italian vocal style at the turn of the century was changing, and Caruso employed a new "modern" style in his singing. His interpretive decisions, vocal method, and repertoire which he championed had an impact on the vocal tradition of future generations. Comparison of his recordings with tenors Fernando de Lucia, Giuseppe Anselmi, and Alessandro Bonci shows a marked contrast in styles of "the old school" and Caruso's "more straightforward" approach. A collection of historical documents for those who succeeded him include many biographies, reviews, and quotes to demonstrate the extent of his influence. Recordings also show a movement toward "the Caruso Sound." Jussi Bjoerling, Franco Corelli, Richard Tucker, Mario Lanza, and Luciano Pavarotti were all influenced by the great Caruso. Almost 100 ...

Determinants of Principal Pay in the State of Texas

Determinants of Principal Pay in the State of Texas

Date: 2016-5
Creator: Asbury, Elizabeth
Description: The purpose of the study was to examine district, campus, and community determinants of principal’s salaries using a spatial econometric framework. Among the district variables business tax (p = 0.001), property tax (p < .01), and the Herfindahl Index (measure of competition) were statistically significant indicators of principal salaries. The results suggest that more affluent districts tend to pay principals higher salaries, which was expected. Regarding campus characteristics, the percent of economically disadvantaged was not a statistically sound indicator (p = 0.468), but campus enrollment was significant (p = <.01). Interestingly as the percentage of economically disadvantaged students increased, the principal salary decreased. In contrast, as student enrollment increases the salary of principals increases, suggesting that principals of larger campuses earn higher salaries. Interestingly, student achievement was not a statistically significant predictor of principals’ salary given that pay for performance in Texas is at the forefront of political debate. Among the variables examined at the community level, only the percentage of homes owner occupied (p = 0.002) was found to be a statistically significant indicator of principal salary (p = .002). The lack of evidence on reforms, such as determinants of principal salary, points to data and research deficiencies to ...

A Model of Collaborative Creativity: The Arrangements of Nelson Riddle for Frank Sinatra and Ella Fitzgerald

A Model of Collaborative Creativity: The Arrangements of Nelson Riddle for Frank Sinatra and Ella Fitzgerald

Date: 2016-5
Creator: Evens, Gabriel I.
Description: This dissertation explores the themes of collaboration and creativity in the relationship between arranger Nelson Riddle and vocalists Frank Sinatra and Ella Fitzgerald. It examines the balance between structure and freedom as well as the specific musical results that emerge from collaboration between an arranger and vocalists who are considered among the greatest in their fields. An examination of their interactions, musical scores, and performances, reveals that the constraints that are present in a collaborative effort can lead the artists to find a shared process to make a creative, unified product.

Development of an Instrument to Measure the Level of Acceptability and Tolerability of  Cyber Aggression: Mixed-Methods Research on Saudi Arabian Social Media Users

Development of an Instrument to Measure the Level of Acceptability and Tolerability of Cyber Aggression: Mixed-Methods Research on Saudi Arabian Social Media Users

Access: Use of this item is restricted to the UNT Community.
Date: 2016-5
Creator: Albar, Ali A
Description: Cyber aggression came about as a result of advances in information communication technology and the aggressive usage of the technology in real life. Cyber aggression can take on many forms and facets. However, the main focus of this study is cyberbullying and cyberstalking through information sharing practices that might constitute digital aggressive acts. Human aggression has been extensively investigated. Studies focusing on understanding the causes and effects that can lead to physical and digital aggression have shown the prevalence of cyber aggression in different settings. Moreover, these studies have shown strong relationship between cyber aggression and the physiological and physical trauma on both perpetrators and their victims. Nevertheless, the literature shows a lack of studies that could measure the level of acceptance and tolerance of these dangerous digital acts. This study is divided into two main stages; Stage one is a qualitative pilot study carried out to explore the concept of cyber aggression and its existence in Saudi Arabia. In-depth interviews were conducted with 14 Saudi social media users to collect understanding and meanings of cyber aggression. The researcher followed the Colaizzi’s methods to analyze the descriptive data. A proposed model was generated to describe cyber aggression in social media ...

Child Centered Play Therapy with Children Exhibiting Aggressive Behaviors

Child Centered Play Therapy with Children Exhibiting Aggressive Behaviors

Date: 2016-5
Creator: Wilson, Brittany Jean
Description: Aggressive behaviors in childhood currently serve as the leading cause of counselor referrals within the United States. Children exhibiting maladaptive aggressive symptomology are at an increased risk for highly externalized and problematic behaviors across the lifespan. Emotional self-regulation and empathy are two constructs currently believed to be closely related to aggression, but a lack of research exploring these variables currently exists in the counseling literature. In this study I examined the effect of child-centered play therapy (CCPT), is a manualized, developmentally responsive, and nondirective intervention, on these variables. Participants were 71 students from four Title 1 elementary schools in the southwest U.S. referred by teachers for aggressive behavior (12 females, 59 males; age range 5-10 years with mean age 6.28. The sample consisted of 52.1% (n = 37) children identified as African American, 21.1% (n = 15) as Latina/Latino, 19.7% (n = 14) as Caucasian, and 7% as multiracial (n = 5). Participants were randomly assigned to 8 weeks of a twice-weekly CCPT experimental group (n = 36) or a waitlist control group (n = 35). Results of descriptive discriminant analyses (DDA) of the Social Emotional Assets and Resilience Scale and the Children’s Aggression Scale scores revealed that parents perceived ...

Feasibility of a New Technique to Determine Dynamic Tensile Behavior of Brittle Materials

Feasibility of a New Technique to Determine Dynamic Tensile Behavior of Brittle Materials

Date: 2016-5
Creator: Dean, Andrew W
Description: Dynamic tensile characterization of geo-materials is critical to the modeling and design of protective structures that are often made of concrete. One of the most commonly used techniques currently associated with this type of testing is performed with a Kolsky bar and is known as the spall technique. The validity of the data from the spall technique is highly debated because the necessary boundary conditions for the experiment are not satisfied. By using a technique called pulse shaping, a new “controlled” spall technique was developed to satisfy all boundary conditions so that the analyzed data may be useful in modeling and design. The results from this project were promising and show the potential to revolutionize the way Kolsky bar testing is performed.

A Phenomenology of Fostering Learning: Alternate Reality Games and Transmedia Storytelling

A Phenomenology of Fostering Learning: Alternate Reality Games and Transmedia Storytelling

Access: Use of this item is restricted to the UNT Community.
Date: 2016-5
Creator: Wakefield, Jenny S
Description: This dissertation presents the essence of the experience of instructional designers and instructors who have used alternate reality games (ARGs) and transmedia storytelling (TS) for teaching and learning. The use of game-like narratives, such as ARGs and TS, is slowly increasing. However, we know little about the lived experiences of those who have implemented such transmedia experiences in formal or informal learning. The data consists of written transcripts from interviews with 11 co-researchers in the United States and Europe. Phenomenology was the guiding methodology. The study begins by reviewing storytelling and the use of games in learning, leading up to exploring the tradition of using ARGs and TS in learning contexts. The analysis was one of reduction leading to codes, summary stories, themes, and the essence of the experience. Co-researchers used many techniques to enlighten their learners including problem-solving, critical thinking, collaboration, encouragement, disruption, and connection-making. When successful, connection-making facilitates learner agency development by providing learners with the power to act by their own initiative. Action came through the communicated narratives and games that closely tied to real-world problems. In the context of these efforts, this study's co-researchers emerged as educational life-world learning-coaches, "sensei", who were each using strategies and ...
