Advancing a Community's Conversations About and Engagement with Climate Change
The goal of this project completed for the Greater Northfield Sustainability Collaborative (GNSC) was to understand how Northfield, Minnesota citizens are experiencing climate change. Thirty individuals were interviewed to find out what they know about climate change, what actions they are taking, what they think the solutions are to the problems, and what barriers they have to more fully engaging with climate change issues. The interview results are intended to promote and advance the community's discussion on climate change via social learning and community engagement activities such as town hall forums and community surveys. These activities encourage citizens in the community to have direct input into the development of the community's climate action plan (CAP). Analysis of the interviews showed that the interviewees are witnessing climate change, that most are taking at least some action such as recycling or lowering thermostats, that they can name barriers to their own inaction, that they say communication about climate change remains confusing and is not widespread in Northfield, and that they are able to provide numerous suggestions for what the local and broader leadership should be doing. The analysis also showed wide individual variation within the group. Interviewees who were less knowledgeable about …

Adventure in the Classroom: Role and Practices of Adventure Therapy in School Counseling Curriculum
The purpose of this study was to explore the role and impact of adventure therapy (AT) on student development and to identify the greatest challenges to the implementation of AT in schools. The Delphi method was used to generate consensus of opinion within a group of experts in the field of adventure therapy and school counseling. Purposive sampling was used to identify the members of the expert panel and the definition of consensus was set at 80% for each item. Content and descriptive analysis were used to develop representative statements from participant responses between rounds. Ten Caucasian respondents, 6 men and 4 women, having met at least one of the expert criteria for the study, completed three rounds of participation which resulted in the attainment of consensus on 36 items addressing the role of adventure therapy in school counseling and the impact of AT in the areas of academic/career and social/emotional development. Twelve challenges to the implementation of AT in schools were identified and put in rank order. According to the results, experts believe adventure therapy has the greatest impact on social connectedness, problem solving, and student engagement in schools. Access to appropriate training in AT, administrative support, and funding …

Analysis of Mature and Young Thrombocytes in Zebrafish
Eukaryotic platelets are small cell fragments that are released into the bloodstream from megakaryocytes, and their production is initiated in the bone marrow. They are mainly involved in blood hemostasis and thrombus formation. The newly synthesized platelets are called reticulated platelets or young platelets. Zebrafish thrombocytes are equivalent to mammalian platelets and have similar characteristics and functions. Likewise, zebrafish has both young and mature thrombocytes. Only young thrombocytes as reticulated platelets are labeled with thiazole orange. Similarly, labeling zebrafish thrombocytes with a specific concentration of DiI-C18 showed two populations of thrombocytes (DiI+ and DiI-). Again, only young thrombocytes showed DiI+ labeling. The mechanism of selective labeling of young thrombocytes by is unknown. Furthermore, there is no zebrafish line where young and mature thrombocytes are differentially labeled with fluorescence proteins. Therefore, in this study, we identified and confirmed that the RFP labeled cells of Glofish were young thrombocytes. In addition, we found that myosin light chain 2 (MLC2) promoter is expressed in young thrombocytes. We also generated a transgenic zebrafish line, GloFli fish, where the young and mature thrombocytes are labeled with red and green fluorescence proteins respectively. Furthermore, this study showed a two-fold increase in glycerol-phospholipids (GP) in mature thrombocytes …

Analyzing Tradeoffs between Privacy Concerns and Active Social Media Presence of 18- to 30-Year-Old College Students
This study applied the impression management theory in the context of social networking to investigate the generalized research question of this dissertation which is "Do active social media presence and various privacy concerns influence online behaviors of students on social media?" The results and conclusions are presented via the conduct of three different studies and the summary provides insights and explain the overall contribution of the research. For each study we developed a research model for which data was collected separately for each of these models. Hypotheses of each model were tested by partial least squares- structural equation modeling techniques using SmartPLS 2.0. Our findings confirm the hypotheses and showed that all the predictors positively influence online social networking behaviors. Active social media presence is operationalized as predictors such as SNS stalking awareness, Selective disclosure, desired differential persona, impression motivation, and information trustworthiness. Privacy concerns have been operationalized as SNS privacy awareness, technology awareness. Online behaviors have been operationalized as responsible image and reckless image.

Application of Statistical Physics in Human Physiology: Heart-Brain Dynamics
This dissertation is devoted to study of complex systems in human physiology particularly heartbeats and brain dynamics. We have studied the dynamics of heartbeats that has been a subject of investigation of two independent groups. The first group emphasized the multifractal nature of the heartbeat dynamics of healthy subjects, whereas the second group had established a close connection between healthy subjects and the occurrence of crucial events. We have analyzed the same set of data and established that in fact the heartbeats are characterized by the occurrence of crucial and Poisson events. An increase in the percentage of crucial events makes the multifractal spectrum broader, thereby bridging the results of the former group with the results of the latter group. The crucial events are characterized by a power index that signals the occurrence of 1/f noise for complex systems in the best physiological condition. These results led us to focus our analysis on the statistical properties of crucial events. We have adopted the same statistical analysis to study the statistical properties of the heartbeat dynamics of subjects practicing meditation. The heartbeats of people doing meditation are known to produce coherent fluctuations. In addition to this effect, we made the surprising …

Applications of Metallic Clusters and Nanoparticles via Soft Landing Ion Mobility, from Reduced to Ambient Pressures
Nanoparticles, simple yet groundbreaking objects have led to the discovery of invaluable information due to their physiological, chemical, and physical properties, have become a hot topic in various fields of study including but not limited to chemistry, biology, and physics. In the work presented here, demonstrations of various applications of chemical free nanoparticles are explored, from the determination of a non-invasive method for the study of the exposome via using soft-landing ion mobility (SLIM) deposited nanoparticles as a matrix-assisted laser desorption/ionization (MALDI-MS) matrix replacement, to the direct SLIM-exposure of nanoparticles onto living organisms. While there is plenty of published work in soft-landing at operating pressures of 1 Torr, the work presented here shows how this technology can be operated at the less common ambient pressure. The ease of construction of this instrument allows for various modifications to be performed for a wide array of applications, furthermore the flexibility in metallic sample, operating pressure, and deposition time only open doors to many other future applications. The work presented will also show that our ambient SLIM system is also able to be operated for toxicological studies, as the operation at ambient pressure opens the door to new applications where vacuum conditions are …

The Art of Marimba Articulation: A Guide for Composers, Conductors, and Performers on the Expressive Capabilities of the Marimba
Articulation is an element of musical performance that affects the attack, sustain, and the decay of each sound. Musical articulation facilitates the degree of clarity between successive notes and it is one of the most important elements of musical expression. Many believe that the expressive capabilities of percussion instruments, when it comes to musical articulation, are limited. Because the characteristic attack for most percussion instruments is sharp and clear, followed by a quick decay, the common misconception is that percussionists have little or no control over articulation. While the ability of percussionists to affect the sustain and decay of a sound is by all accounts limited, the ability of percussionists to change the attack of a sound with different implements is virtually limitless. In addition, where percussion articulation is limited, there are many techniques that allow performers to match articulation with other instruments. Still, percussion articulation is often a topic of little concern to many musicians. The problem is not that this issue has been completely ignored, but rather that a vast number of contradictory and conflicting viewpoints still permeate pedagogical methods and literature. This is most certainly the case with the marimba, where a review of method books reveals …

Art Unfettered: Bergson and a Fluid Conception of Art
This dissertation applies philosopher Henri Bergson's methodology and his ideas of duration and creativity to the definitional problem of art, particularly as formulated within analytic aesthetics. In mid-20th century, analytic aesthetics rejected essentialist definitions of art, but within a decade, two predominant definitions of art emerged as answers to the anti-essentialism of the decade prior: functionalism and proceduralism. These two definitions define art, respectively, in terms of the purpose that art serves and in terms of the conventions in place that confer the status of art onto artifacts. Despite other important definitions (including historical and intentionalist definitions), much of the literature in the analytic field of aesthetics center on the functional/procedural dichotomy, and this dichotomy is an exclusive one insofar as the two definitions appear incompatible with each other when it comes to art. I use Bergson's methodology to demonstrate that the tension between functionalism and proceduralism is an artificial one. In turn, abandoning the strict dichotomy between these two definitions of art opens the way for a more fluid conception of art. Using Bergson's application of duration and creativity to problems of laughter and morality, I draw parallels to what a Bergsonian characterization would entail.

Assessing Perception and Attitude of Pianists toward Ergonomically Scaled Piano Keyboards (ESPK): Raising Awareness about ESPK and Evaluating Changes of Attitude through an Educational Survey
As epidemiologic research demonstrates health concerns for hand problems among pianists, scientists are measuring historic piano keyboards and realizing that much of the piano literature was composed for and played on pianos with smaller keys compared to what is used on the modern piano. Having to play this literature on a larger keyboard is especially difficult for small-handed piano students and professionals. Fortunately, smaller keyboards are now available for use with standard pianos - and research shows that this ergonomic adjustment does reduce piano-related hand pain for small-handed musicians. Major universities are now offering this option to students, but only a few music schools possess these keyboards and not many people know about them. There are no known research studies to address people's awareness and attitude toward ergonomically scaled piano keyboards (ESPKs). The purpose of this study was to assess perception and attitude toward ESPKs and help to raise its awareness. To examine pianists' perception, two surveys was composed. First one was conducted on UNT campus in which ESPKs are available for their students, and the second survey was carried out on schools of music in the United States. The results reveal that substantial number of people already know about …

Assessment of Caregiver Generalization of Reinforcement to the Natural Environment in a Large Residential Facility and Use of Prompting and Feedback to Improve Performance
Behavioral skills training (BST) is often used to train caregivers to implement various behavior management procedures; however, additional strategies are sometimes required to promote the generalization of skills from a contrived setting to the natural environment. Generalizing skills to the natural environment requires that the caregiver's behavior transfer from control of stimuli in the contrived setting to stimuli in the natural environment, and the skill continues to be performed with high levels of accuracy. The purpose of this study was to assess the extent to which caregivers generalized the use of social reinforcement, in the form of descriptive praise, from the contrived setting to the natural environment. When caregivers failed to respond to opportunities, a progressive prompt delay was used to bring caregivers' responding under the control of relevant client behavior; feedback was used to improve the accuracy with which caregivers implemented reinforcement. Five caregivers in a large residential facility participated in the study; single-opportunity probes were used to assess caregiver's identification of opportunities and accuracy in implementing reinforcement for two defined client behaviors, compliance and appropriate attention-getting behavior. Results of the study suggest that skills failed to generalize from the contrived setting to the natural environment. However, prompting was …

Ben Thompson: Portrait of a Gunfighter
Access:
Use of this item is restricted to the UNT Community
Ben Thompson was a remarkable man, and few Texans can claim to have crowded more excitement, danger, drama, and tragedy into their lives than he did. He was an Indian fighter, Texas Ranger, Confederate cavalryman, mercenary for a foreign emperor, hired gun for a railroad, an elected lawman, professional gambler, and the victor of numerous gunfights. As a leading member of the Wild West’s sporting element, Ben Thompson spent most of his life moving in the unsavory underbelly of the West: saloons, dance-houses, billiard halls, bordellos, and gambling dens. During these travels many of the Wild West’s most famous icons—Wyatt Earp, Doc Holliday, Bat Masterson, Wild Bill Hickok, John Wesley Hardin, John Ringo, and Buffalo Bill Cody—became acquainted with Ben Thompson. Some of these men called him a friend; others considered him a deadly enemy. In life and in death no one ever doubted Ben Thompson’s courage; one Texas newspaperman asserted he was “perfectly fearless, a perfect lion in nature when aroused.” This willingness to trust his life to his expertise with a pistol placed Thompson prominently among the western frontier’s most flamboyant breed of men: gunfighters.

Bread, Bullets, and Brotherhood: Masculine Ideologies in the Mid-Century Black Freedom Struggle, 1950-1975
This thesis examines the ways that African Americans in the mid-twentieth century thought about and practiced masculinity. Important contemporary events such as the struggle for civil rights and the Vietnam War influenced the ways that black Americans sought not only to construct masculine identities, but to use these identities to achieve a higher social purpose. The thesis argues that while mainstream American society had specific prescriptions for how men should behave, black Americans were able to select which of these prescriptions they valued and wanted to pursue while simultaneously rejecting those that they found untenable. Masculinity in the mid-century was not based on one thing, but rather was an amalgamation of different ideals that black men (and women) sought to utilize to achieve communal goals of equality, opportunity, and family.

China Naval Modernization: Implications for U.S. Navy Capabilities--Background and Issues for Congress
This report provides background information and issues for Congress on China's naval modernization effort and its implications for U.S. Navy capabilities. The question of how the United States should respond to China's military modernization effort, including its naval modernization effort, is a key issue in U.S. defense planning and budgeting. Many U.S. military programs for countering improving Chinese military forces (particularly its naval forces) fall within the U.S. Navy's budget.
