This thesis aims to utilize data analysis and predictive modeling techniques and apply them in different domains for gaining insights. The topics were chosen keeping the same in mind. Analysis of customer interests is a crucial factor in present marketing trends and hence we worked on twitter data which is a significant part of digital marketing. Neuroscience, especially psychological behavior, is an important research area. We chose eye tracking data based on which we differentiated human concentration while watching controllable (video game) videos and uncontrollable (sports) videos. Currently, cities are using data analysis for becoming smart cities. We worked on the City of Lewisville emergency services data and predicted the vehicle-accident-prone areas for development of precautionary measures in those areas.

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 …

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.

An artificially structured boundary (ASB) produces a short-range, static electromagnetic field that can reflect charged particles. In the work presented, an ASB is considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. When used to create an enclosed volume, an ASB may confine a non-neutral plasma that is effectively free of applied electromagnetic fields, provided the spatial period of the ASB-applied field is much smaller than any one dimension of the confinement volume. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space-charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for antimatter gravity studies may be possible. A classical trajectory Monte Carlo (CTMC) simulation suite has been developed in C++ to efficiently simulate charged particle interactions with user defined electromagnetic fields. The code has been used to explore several ASB configurations, and a concept for a cylindrically symmetric ASB trap that employs a picket-fence magnetic field has been developed. Particle-in-cell (PIC) modeling has been utilized to investigate the confinement of non-neutral and partially neutralized positron plasmas in the trap.

This article describes how measures of need, participation, satisfaction, and impact are employed to assess many aspects of a professional development program in a large academic library.

A brief reading assessment and preference assessment were conducted with three participants with developmental and learning disabilities (i.e., two participants were diagnosed with Autism, the third participant was diagnosed with intellectual disability) who did not acquire fluent reading in previous individualized instruction. The results of the brief reading assessment were analyzed in an alternating treatment design and a preference assessment was conducted to determine the participants' preferred reading intervention. Following the results of the two assessments, a reading intervention that matched effectiveness with preference when possible or favored effectiveness when a match was not possible. The selected interventions (and later combined interventions) were implemented for each participant using an A-B-A-C or an A-B-A-C-D design. The results suggest that the four reading strategies are effective options for improving reading fluency. Also, a brief reading assessment can help identify an effective reading strategy. The results are discussed in the context of fluency gains, limitations, and implications for future research.

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 …

Presentation for the 2018 Library Assessment Conference. This presentation describes the assessment of a mentoring program at an academic library.

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 …

This investigation was a post-hoc, quantitative analysis of secondary academic performance and participation choices of Hispanic students. Three years of longitudinal student-level data was collected to examine the likelihood of college enrollment based on college and career readiness (CCR) factors. At the time of the study, CCR was defined as qualifying exam scores, credit for at least two advanced/dual enrollment courses, or enrollment in a career and technology education (CTE) coherent sequence of courses. Research participants (N = 803) consisted solely of Hispanic high school graduates from the 2014 cohort. Frequency statistics indicate 45.5% (n = 365) attended an institute of higher education (IHE) within 2 years of high school graduation. Findings reveal Hispanic females were more likely than Hispanic males to meet CCR indicators as well as postsecondary resiliency outcomes. Analysis of chi-square tests of independence suggests a moderately strong association exists between CCR indicators and postsecondary participation among high school graduates. Differences were found in terms of gender and postsecondary enrollment, x^2(6) = 24.538, p < .001. Differences were also found in terms of type of IHE and postsecondary resiliency, x^2(3) = 34.373, p < .001. More Hispanic CCR graduates enrolled at 2-year and 4-year IHE than expected …

The present study aims to examine which maladaptive and Big Five personality traits, as well as which lower order facets, are related to symptoms specific to PTSD (i.e., intrusions and avoidance). Unique effects were isolated by controlling for nonspecific general depression that occurs in the disorder but is not specific to it. 707 undergraduate students were administered a self-report online survey to assess their personality, trauma history, PTSD and mood symptoms. Additionally, data from 536 9/11 World Trade Center (WTC) responders who have been administered personality, PTSD, and mood surveys as part of a longitudinal study were analyzed. As expected, neuroticism was highly correlated with PTSD, but had fewer associations with PTSD dimensions after controlling for depression. Trust and agreeableness emerged as important, being negatively related to PTSD, while most maladaptive personality domains and facets were positively related to PTSD (perceptual dysregulation had the highest association). Other traits, such as antagonism and openness, were not significantly related to PTSD. There is growing evidence that clinical interventions can change personality traits; the present study provides new personality targets for intervention that are uniquely related to PTSD.

Discrimination of different tree crowns based on their 3D shapes is essential for a wide range of forestry applications, and, due to its complexity, is a significant challenge. This study presents a modified 3D shape descriptor for the perception of different tree crown shapes in discrete-return LiDAR point clouds. The proposed methodology comprises of five main components, including definition of a local coordinate system, learning salient points, generation of simulated LiDAR point clouds with geometrical shapes, shape signature generation (from simulated LiDAR points as reference shape signature and actual LiDAR point clouds as evaluated shape signature), and finally, similarity assessment of shape signatures in order to extract the shape of a real tree. The first component represents a proposed strategy to define a local coordinate system relating to each tree to normalize 3D point clouds. In the second component, a learning approach is used to categorize all 3D point clouds into two ranks to identify interesting or salient points on each tree. The third component discusses generation of simulated LiDAR point clouds for two geometrical shapes, including a hemisphere and a half-ellipsoid. Then, the operator extracts 3D LiDAR point clouds of actual trees, either deciduous or evergreen. In the fourth …

The goal of this study was to build on the historic use of the avian model of development and also to further the knowledge of autonomic nervous system (ANS) regulation of cardiovascular function in vertebrates. Vasoactive drugs sodium nitroprusside, a vasodilator and phenylephrine, a vasoconstrictor were used to study the correlation of cardiovascular function relationship with nerve activity, both sympathetic and parasympathetic (vagal). Additionally, ANG II was used to assess its effects on vagal inhibition. The present study shows that pharmacologically-induced hypertension is associated with a fall in mSNA, indicating that the capacity for sympathetic autonomic cardiovascular regulation is established by late incubation however, late-stage embryonic chickens did not show a significant increase in mSNA during hypotension. The hypotensive response of the embryo was not accompanied by the expected inhibition of vagal discharge; however a slight but insignificant reduction in vagal discharge was noted. When vagal efferent output was isolated, a significant drop in vagal efferent activity was noted in response to hypotension. The present study showed late-stage embryonic chickens lack a vagal response to hypertension in both efferent and sensory limbs. In this study, vagal discharge was reduced from baseline levels in response to Ang II. Collectively, the present …

Through the use of natural history records, published literature, and personal sampling (2011-2016) a total of 454 caddisfly species represented by 24 families and 93 genera were documented from the south-central United States. Two Hydroptilidae species were collected during the 2011-2016 collection efforts that are new to the region: Hydroptilia scheringi and Mayatrichia tuscaloosa. Eightteen species are endemic and 30 are considered species of concern by either federal or state agencies. The majority of each of these groups is Hydroptilidae, or microcaddisflies. Trichoptera community structure, by minimum number of species, was analysed in conjunction with large-scale geographical factors to determine which factor illustrated caddisfly community structure across the region. Physiographic provinces compared to other geographic factors analyzed best-represented caddisfly communities with a minimum of 10 or more species. Statistically, Hydrologic Unit Code 4 (HUC 4) was the most significant geographical factor but low number of samples representing this variable rendered it less representative of caddisfly community structure for the study area.

According to a recent United Nations report, China's population of 1.4 billion represents 19% of the world's entire population of 7.6 billion. As the distance between east and west contracts in business, so too do the arts. This dissertation focuses on six selected contemporary Chinese art songs composed by Nan-Chang Chien. By providing the references of musical facts, synopsis of the poems, word-for-word translation, IPA transcription, poetic translation, and interpretive and performance guides, singers and pianists will have an overall understanding and detailed directions for learning the Chinese language and Chinese art songs. This dissertation also provides the foundation and model for further exploration and research into Chinese art sing literature by scholars in the west.
