Sustainable Ecofriendly Insulation Foams for Disaster Relief Housing

Description: Natural disasters are affecting a significant number of people around the world. Sheltering is the first step in post-disaster activities towards the normalization of the affected people's lives. Temporary housing is being used in these cases until the construction of permanent houses are done. Disposal of temporary housing after use is leading to a significant environmental impact because most of them are filled with thermally insulative polymer foams that do not degrade in a short period. To reduce these problems this work proposes to use foams made with compostable thermoplastic polylactic acid (PLA) and degradable kenaf core as filler materials; these foams are made using CO2 as blowing agent for insulation purposes. Foams with PLA and 5%, 10% and 15% kenaf core were tested. Different properties and their relations were examined using differential scanning calorimetry (DSC), thermal conductivity, mechanical properties, scanning electron microscopy (SEM), x-ray μ-computed tomography (μ-CT) and building energy simulations were done using Energy Plus by NREL. The results show that mechanical properties are reduced with the introduction of kenaf core reinforcement while thermal conductivity display a noticeable improvement.

Automated GUI Tests Generation for Android Apps Using Q-learning

Description: Mobile applications are growing in popularity and pose new problems in the area of software testing. In particular, mobile applications heavily depend upon user interactions and a dynamically changing environment of system events. In this thesis, we focus on user-driven events and use Q-learning, a reinforcement machine learning algorithm, to generate tests for Android applications under test (AUT). We implement a framework that automates the generation of GUI test cases by using our Q-learning approach and compare it to a uniform random (UR) implementation. A novel feature of our approach is that we generate user-driven event sequences through the GUI, without the source code or the model of the AUT. Hence, considerable amount of cost and time are saved by avoiding the need for model generation for generating the tests. Our results show that the systematic path exploration used by Q-learning results in higher average code coverage in comparison to the uniform random approach.

Probabilistic Analysis of Contracting Ebola Virus Using Contextual Intelligence

Description: The outbreak of the Ebola virus was declared a Public Health Emergency of International Concern by the World Health Organisation (WHO). Due to the complex nature of the outbreak, the Centers for Disease Control and Prevention (CDC) had created interim guidance for monitoring people potentially exposed to Ebola and for evaluating their intended travel and restricting the movements of carriers when needed. Tools to evaluate the risk of individuals and groups of individuals contracting the disease could mitigate the growing anxiety and fear. The goal is to understand and analyze the nature of risk an individual would face when he/she comes in contact with a carrier. This thesis presents a tool that makes use of contextual data intelligence to predict the risk factor of individuals who come in contact with the carrier.

Extending the Apprenticeship through Informal Learning on Facebook: An Interpretative Phenomenological Analysis of the Lived Experiences of Music Faculty

Description: Facebook studio groups/pages are commonly used by applied music faculty to communicate with current students, recruit new students, share students' activities, and promote faculty members' professional performances and academic endeavors. However, the blurred lines between academic, professional performance, and social activities in the field have led to a wide variety of approaches to Facebook use by music faculty. This dissertation documents the first generation of music faculty social media users and investigates the beliefs, intent, and lived experiences of music faculty who use Facebook studio groups/pages to communicate with their students. Four music faculty were interviewed and a semester's Facebook studio group/page data collected for each faculty member. Interviews and Facebook data were analyzed using Interpretative phenomenological analysis (IPA) to identify emergent, and ultimately super-ordinate, themes from the data. The three super-ordinate themes that emerged were: Impact of Social Media on Studio Teaching and Learning, Learning through Enculturation, and Faculty Lived Experiences with Facebook Studio Groups/Pages. Findings of the study included: faculty concerns about personal and professional risk; the observation that teaching and learning are occurring through these Facebook studio groups/pages by way of the process of enculturation, but without evidence of a Virtual Community of Practice; and, a multitude of group/page management practices developed in isolation that suggest a need for discussion/debate and training in the field to determine best practices for using Facebook studio groups/pages as an extension of the physical studio. Recommendations include training for music faculty that situates Facebook studio groups/pages within the enculturation process of students pursuing careers in music, music department development of guidelines for Facebook group/page creation and management based upon their institutions' rules and oversight procedures, and the sharing of exemplar Facebook studio groups/pages by professional music education organizations to encourage discussion of best practices for teaching and learning in informal environments.

Elucidation of Photoinduced Energy and Electron Transfer Mechanisms in Multimodular Artificial Photosynthetic Systems

Description: Multimodular designs of electron donor-acceptor systems are the ultimate strategy in fabricating antenna-reaction center mimics for artificial photosynthetic applications. The studied photosystems clearly demonstrated efficient energy transfer from the antenna system to the primary electron donor, and charge stabilization of the radical ion pair achieved with the utilization of secondary electron donors that permits either electron migration or hole transfer. Moreover, the molecular arrangement of the photoactive components also influences the route of energy and electron transfer as observed from the aluminum(III) porphyrin-based photosystems. Furthermore, modulation of the photophysical and electronic properties of these photoactive units were illustrated from the thio-aryl substitution of subphthalocyanines yielding red-shifted Q bands of the said chromophore; hence, regulating the rate of charge separation and recombination in the subphthalocyanine-fullerene conjugates. These multicomponent photosystems has the potential to absorb the entire UV-visible-NIR spectrum of the light energy allowing maximum light-harvesting capability. Furthermore, it permits charge stabilization of the radical ion pair enabling the utilization of the transferred electron/s to be used by water oxidizing and proton reducing catalysts in full-scale artificial photosynthetic apparatuses.

Effects of Student-Created Question Process on Learning Biomedical Statistics in a Specialized Master's in Medical Sciences

Description: This study explored the effectiveness of a student question creation process engaging students actively in self, peer, and instructor interaction in development of affective, cognitive, and meta-cognitive skills. Employing a mixed-methods sequential explanatory design assigning both treatment and control activities sequentially in an alternating pattern over a six week period, students' performance on exams as well as their perceptions of various aspects of the student question creation process were used to evaluate the effectiveness of student-created questions (SCQs) activities as a cognitive strategy and to identify factors contributing to the effectiveness of question creation activities on students' learning. Subjects of this study were high performing and highly motivated graduate students in an 8-week online biomedical statistics course, part of a specialized master's program designed for medical school preparation. Survey findings and focus groups strongly supported the student question creation process as a facilitator of higher order thinking. However, the relatively short study duration, comparison of student question creation with another competing method for facilitating learning (discussion board) and not a pure control group, and availability of a common study guide course with student-created questions on all course topics may have muted assessment of the full impact of the strategy on learning. Although practically difficult in an education environment, further research to assess fully the impact of the student question creation strategy is desirable especially if these confounding factors can be greatly minimized, if not eliminated.

The Relationship between the Advanced Placement Calculus AB Exam and Student Achievement in College Level Math 1710-Calculus I

Description: The purpose of this dissertation was to investigate the relationship between the Advanced Placement Calculus AB exam and student achievement in college level Math 1710-Calculus I. The review of literature shows that this possible relationship is based on Alexander Astin's longitudinal input-environment-outcome (I-E-O) model. The I-E-O model was used to analyze the relationship between the input and outcome of the two variables. In addition, this quantitative study determined the relationship between a score of 3 or lower on the Advanced Placement Calculus AB exam and student achievement in college level Math 1710-Calculus I. The sample population of this study contained 91 students from various high schools in Texas. Spearman's rank correlation revealed there was a statistically significant relationship between Advanced Placement Calculus AB exam scores and final grades in Math 1710-Calculus I.

"Spectral Evidence"

Description: Spectral Evidence is a collection of poems that instigates a variety of omens, signs, divinations, and folktales to explore the concept of wish fulfillment. They arise in obedience to the compulsion to repeat past dramas brought on by failed love, the nostalgia of childhood, the damning legacy of language, the restriction of gender roles, death, etc. In order to quell these anxieties, the speaker looks beyond the self to both history and mythology, often invented mythologies as an attempt to control or recast the story-to give shape to the obscurities of life by creating a system of belief in order to forge meaning or confuse oneself into believing. In many ways this collection is all about belief or in wanting to believe. Through language, God is written into existence. God is the name of the blanket we put over the mystery to give it shape. Here, in this collection, God is an ant's egg. a cherry pit, a colony of white moths, a severed hand, the color red, a little bird. This collection explores these vehicles of meaning, the words that provide the shell of meaning, and the power of invention in hopes to gain control over what is deemed uncontrollable. While the speaker may be casting omens as "pre-ordained" entities outside of her power, it is her convictions in these signs that her own psychological and associative link between their meaning and their appearance that she conjures and creates because the existing systems of language, religion, and belief do not serve her. This creation is what is powerful. It is healing. It is birth. It is not involuntary wish fulfillment. It is the deliberative satisfaction of desire-on of the most insurrectionary acts a woman can execute.

Factors Affecting Faculty Acceptance and Use of Institutional Repositories in Thailand

Description: Institutional repositories have been introduced as an innovative and alternative technology for scholarly communication and have received considerable attention from scholars across disciplines and around the globe. While some universities in Thailand have developed and implemented institutional repositories for nearly a decade, knowledge of the acceptance and use of institutional repositories on the individual level in the country remains limited. As an insufficient knowledge of technology acceptance and adoption at the individual level is considered partially responsible for the underutilization of innovation or of information system implementation, this study seeks to uncover knowledge regarding the level of institutional repository acceptance and use. This study applied the unified theory of acceptance and use of technology (UTAUT) model and the model of faculty members' self-archiving behavior to investigate factors affecting faculty acceptance and use of university-based institutional repositories. The study employed a mixed methods approach involving a survey followed by semi-structured, one-to-one interview. This study confirms that the success of university-based institutional repositories depends not on a single factor but on multiple factors. The results of the study show that performance expectancy, social influence, and resistance to change were direct determinants of faculty members' intention to use institutional repositories. Additionally, behavioral intention and altruism were found to be the main determinants of actual usage behavior. The findings of this study imply that education in and promotion of open access and institutional repositories are essential and can play an important role in the adoption of institutional repositories. Finally, this study suggests that sustained dialogue and collaborative efforts among faculty members (as contributors and users), libraries/librarians (as institutional repository developers and managers), and other stakeholders within communities are essential for the adoption and success of university-based institutional repositories.

The Shrinking Opera Diva: The Impact of Sociocultural Changes upon the Casting of Women in the 20th and 21st Centuries

Description: For most of the twentieth century, opera singers were not beholden to the ideal physical standard of women dictated by popular culture, but rather focused on serving the music and perfecting their artistry. Unprecedented sociocultural changes throughout the twentieth century exposed the shifting ideals of each generation and how they were promoted through mass media and advertising. This thesis surveys the time period of the 1890s to the present day for the purpose of analyzing cultural trends, philosophies and technologies that shaped the century. Societal pressure to make the body a project and the focus of one's own intense attention now reflects back onto the opera stage where audience members expect to see what society has dictated to be an acceptable female form. Artistic and stage directors are influenced by society's decree that only thin is beautiful, imbedding into the mindset of the art form notions that now affect how female professional opera singers are depicted and even employed.

Smartphones and Tablets: Patterns of Usage among College Student Populations

Description: This study offers insight into students' use and desire to use mobile devices for educational purposes. I examined college students' mobile device usage on the basis of demographic factors including sex, age, ethnicity, class standing, mode of delivery, and socioeconomic status. This study also investigated factors that affect students' likelihood to use mobile devices for academic pursuits. I utilized data from the EDUCAUSE Center for Analysis and Research's (ECAR) 2015 Student Technology Survey. Of the 10,000 undergraduate respondents, 56% were female, 70% were between the ages of 18-24, 73% attended college full time and the breakdown of ethnicity included 59% Caucasian, 16% Hispanic, 13% African American, 8% Asian and 1% Native American. The results indicated that traditional aged students reportedly used smartphones more frequently, whereas non-traditional aged students reportedly used tablets more. Students most frequently reported using their devices in class to connect to the learning material. Institutional technology infrastructure and support were strong factors impacting students' use of smartphones. Results of this research can assist higher education faculty and administrators in devising comprehensive training and technology plans to support and encourage students' use of mobile devices for educational purposes.

Simplification and Octavation in Double Bass Performance: An Overview of Historical and Contemporary Practices

Description: Two important performance practices in the modern orchestral performance are discussed in this document: simplification and octavation. Due to the differing opinions and common practices which bass players have around these two performance practices, simplification and octavation have become two of the most complex issues faced by orchestral sections. The first part of the document will provide a brief history of simplification and octavation. The second part of the document will offer recommendation for double bass orchestral practice in the 21st century and examine key works of the bass repertoire in which simplification and octavation occur. The research and practice of leading pedagogues and major orchestral players and the solutions they have developed to reduce the discrepancy inherent within section playing will be discussed. This document will propose several empirical solutions to major excerpts in the bass repertoire, demonstrating how it is to achieve the most uniformed playing, and offer applicable and suggestive guidelines for contemporary orchestral double bass performers.

The Relationship between Judicial Independence and Ethnic Conflict

Description: The relationship between judicial independence and the levels of ethnic conflicts in developing countries has remained a significant research area due to increased cases of the conflicts with lack of judicial independence in the countries. Judicial independence is seen as an essential element of democracy in that an independent judiciary can act as an arbiter between different groups and institutions. The main aim of this study was to examine the relationship between judicial independence and ethnic conflicts empirically. Greater judicial independence should be associated with less ethnic conflict, because an independent court can serve as an arbiter for disputants, and thus lessen the likelihood of conflict. The study involved 128 developing countries over a 30-year period from 1981 to 2010 using secondary data sources and employing statistical methods to test the relationship between judicial independence and the levels of ethnic conflicts. Findings indicate that judicial independence has a statistically significant negative association with the levels of ethnic conflict. Therefore, this study recommends that the governments of developing countries should promote judicial independence as part of solutions for ethnic conflicts .
