Field Validation of Zero Energy Lab Water-to-Water Ground Coupled Heat Pump Model

Heat pumps are a vital part of each building for their role in keeping the space conditioned for the occupant. This study focuses on developing a model for the ground-source heat pump at the Zero Energy lab at the University of North Texas, and finding the minimum data required for generating the model. The literature includes many models with different approaches to determine the performance of the heat pump. Each method has its pros and cons. In this research the equation-fit method was used to generate a model based on the data collected from the field. Two experiments were conducted for the cooling mode: the first one at the beginning of the season and the second one at the peak of the season to cover all the operation conditions. The same procedure was followed for the heating mode. The models generated based on the collected data were validated against the experiment data. The error of the models was within ±10%. The study showed that the error could be reduced by 20% to 42% when using the field data to generate the model instead of the manufacturer’s catalog data. Also it was found that the minimum period to generate the cooling …

Ozone Pollution of Shale Gas Activities in North Texas (open access)

Ozone Pollution of Shale Gas Activities in North Texas

The effect of shale gas activities on ground-level ozone pollution in the Dallas-Fort Worth area is studied in detail here. Ozone is a highly reactive species with harmful effects on human and environment. Shale gas development, or fracking, involves activities such as hydraulic fracturing, drilling, fluid mixing, and trucks idling that are sources of nitrogen oxides (NOX) and volatile organic compounds (VOC), two of the most important precursors of ozone. In this study two independent approaches have been applied in evaluating the influences on ozone concentrations. In the first approach, the influence of meteorology were removed from ozone time series through the application of Kolmogorov-Zurbenko low-pass filter, logarithmic transformation, and subsequent multi-linear regression. Ozone measurement data were acquired from Texas Commission on Environmental Quality (TCEQ) monitoring stations for 14 years. The comparison between ozone trends in non-shale gas region and shale gas region shows increasing ozone trends at the monitoring stations in close proximity to the Barnett Shale activities. In the second approach, the CAMx photochemical model was used to assess the sensitivity of ozone to the NOX and VOC sources associated with shale oil and gas activities. Brute force method was applied on Barnett Shale and Haynesville Shale emission …

"Her Name Was"

Her Name Was is an examination of the oppression of transgender people in a society that is built on the nominalization of cisgender people, those who gender matchers their sex assigned at birth, and how this oppression lends itself to violence. In the summer of 2015, the body of Shade Schuler, an African American transgender woman, was found in a field outside of Dallas, Texas. Ms. Shade is part of an alarming epidemic of escalating levels of targeted violence against the transgender community. This documentary pulls back the curtain as it captures the feelings and struggles of the transgender community as they attempt to navigate and survive in a cis dominating society.

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley, 1848-1870 (open access)

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley, 1848-1870

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley is an examination of the relationships created during the mid-nineteenth century between Anglo and Tejano elites in the five counties that make up the Lower Rio Grande Valley. Conducted through a quantitative lens, the five-chapter study seeks to demonstrate that, although the period between 1848 and 1870 was fraught with conflict and violence, the Anglo and Tejano elite of the Lower Rio Grande Valley came together in cooperation in order not only to survive these troubling times but to prosper. The thesis begins by identifying and analyzing the economic and political elite in the Lower Rio Grande Valley during the 1850s. A new crop of Anglo immigrants arrived with the Mexican-American War, but only a small number willing to assimilate to local Tejano culture were able to leave their mark on the Lower Valley. Chapter 4 relates the effect of the Civil War on the elite of the Lower Valley. It explores the profitable cotton trade during the war and the struggle that both Anglo and Tejano elites faced during Reconstruction. The thesis concludes with a macro-analysis of the twenty-two-year period from 1848-1870. It summarizes overall trends found …

Transformative Learning and Teacher Beliefs: A Comparative Study of International Teacher Experiences

This project aims to explore the beliefs of international teachers regarding the students with whom they work, and the change in those beliefs over time. Participant observation, interviews, and questionnaires were used as tools of collection to address the following research questions: How did teachers' beliefs about students change over time? What variables were significantly associated with the rate of change in teacher beliefs about students? What types of challenges did teaches face while living and working in Thailand? Over the course of four months, I shadowed twenty-two U.S. teachers in thirteen different locations throughout Thailand. Participants were enrolled in an international teaching program in Thailand that provided a cultural orientation and teacher training. Participants were then assigned to teaching jobs throughout the country. Qualitative and quantitative data was analyzed using SPSS and NVivo software.

Giving Texas Veterans a Voice: Traumatic Experience and Marijuana Use (open access)

Giving Texas Veterans a Voice: Traumatic Experience and Marijuana Use

Disabled veterans with post-traumatic stress disorder (PTSD) exist in a category separate from many civilians and soldiers. Their experiences land them in a category distinctly marked as atypical. The standard protocol to manage this atypical subject position is prescription drugs- a mark of the ill. In a distorted, post-war American society, what happens when veterans with PTSD refuse to be labeled as ‘sick,' ‘different,' or even ‘disabled'? This thesis explores the actions and intricacies of a community of veterans who advocate for medical cannabis to manage associated symptoms of PTSD. This group of veterans campaigns for individuality, both in medical treatment and in personal experience. Collaboratively, their experiential evidence indicates that none can be treated in the same fashion. After a year of participant observation and field work, it becomes apparent that their work both individualizes and unifies the veterans. This thesis details their experiences and the results of their activist campaign to demarcate themselves.

Mental Illness Stigma, Parent-Child Communication, and Help-Seeking of Young American Adults with Immigrant Parents (open access)

Mental Illness Stigma, Parent-Child Communication, and Help-Seeking of Young American Adults with Immigrant Parents

This study examined a mediational model of mental illness stigma, parent-child communication about mental health concerns, and help seeking attitudes/behaviors among young adults with at least one immigrant parent while considering the possible moderating effect of acculturation gap. The primary goal of this study was to examine whether the acculturation gap changed the relation between mental illness stigma and communication about personal mental health concerns with immigrant parents, which in turn could become a significant predictor of their help-seeking attitudes, as well as a barrier to seeking professional mental health services. Findings provided support to the direct and indirect effects of mental illness stigma through communication about mental health concerns on attitudes about help-seeking. The acculturation gap hypothesized to be a possible moderator for the stigma-communication about mental health concerns relationship among young adult ABCI was found to be significant for ABCI with a low mainstream culture acculturation gap. Discussion on the findings, limitations of the study, future research directions, and counseling implications are addressed.

Island Empire: the Influence of the Maceo Family in Galveston (open access)

Island Empire: the Influence of the Maceo Family in Galveston

From the 1920s until the 1950s, brothers, Sam and Rosario Maceo, ran an influential crime family in Galveston, Texas. The brothers’ success was largely due to Galveston’s transient population, the turbulent history of the island, and the resulting economic decline experienced at the turn of the 20th century. Their success began during Prohibition, when they opened their first club. The establishment offered bootlegged liquor, fine dining, and first class entertainment. After Prohibition, the brothers continued to build an empire on the island through similar clubs, without much opposition from the locals. However, after being suspected of involvement in a drug smuggling ring, the Maceos were placed under scrutiny from outside law enforcement agencies. Through persistent investigations, the Texas Rangers finally shut down the rackets in Galveston in 1957. Despite their influence through the first half of the 20th century, on the island and off the island, their story is largely missing from the current literature.

Use of Bio-Product/Phase Change Material Composite in the Building Envelope for Building Thermal Control and Energy Savings (open access)

Use of Bio-Product/Phase Change Material Composite in the Building Envelope for Building Thermal Control and Energy Savings

This research investigates the bio-products/phase change material (PCM) composites for the building envelope application. Bio-products, such as wood and herb, are porous medium, which can be applied in the building envelope for thermal insulation purpose. PCM is infiltrated into the bio-product (porous medium) to form a composite material. The PCM can absorb/release large amount of latent heat of fusion from/to the building environment during the melting/solidification process. Hence, the PCM-based composite material in the building envelope can efficiently adjust the building interior temperature by utilizing the phase change process, which improves the thermal insulation, and therefore, reduces the load on the HVAC system. Paraffin wax was considered as the PCM in the current studies. The building energy savings were investigated by comparing the composite building envelope material with the conventional material in a unique Zero-Energy (ZØE) Research Lab building at University of North Texas (UNT) through building energy simulation programs (i.e., eQUEST and EnergyPlus). The exact climatic conditions of the local area (Denton, Texas) were used as the input values in the simulations. It was found that the EnergyPlus building simulation program was more suitable for the PCM based building envelope using the latent heat property. Therefore, based on the …

Retail District Evolution: An Exploration of Retail Structure and Diversity, a Case Study in Denton, Texas

It is well established that national retail chains impact small, single location retail businesses in terms of revenue generation, retail structure, retail type diversity, and location. This study examines the retail structure and diversity of five retail districts in the City of Denton, Texas. The analysis focuses on one central business district (CBD), one traditional retail strip center (University Drive, also known as US HWY 380), one special retail district (Fry Street District), one traditional enclosed shopping mall and associated development (Golden Triangle Mall), and one power retail center (Denton Crossing). The empirical foundation for the investigation is a historical business database covering years 1997 to 2010, obtained from Info Group's Reference USA. This Reference USA database includes location, industry, and status (single versus chain location) information for each business. Retail diversity and evenness were measured for each of the five retail districts using the Simpson's Diversity Index and the Simpsons Measure of Evenness, leading to specification of the differences that exist in retail structure and diversity among the districts. Golden Triangle Mall and Denton Crossing were primarily chain location in composition while Fry Street District, the CBD, and University Drive were primarily single location in composition.

Lone Star Insanity: Efforts to Treat the Mentally Ill in Texas, 1861-1929

During the mid-nineteenth century, the citizens of Texas were forced to keep their mentally disturbed family members at home which caused stress on the caregivers and the further debilitation of the afflicted. To remedy this situation, mental health experts and Texas politicians began to create a system of healing known as state asylums. The purpose of this study is to determine how Texas mental health care came into being, the research and theories behind the prevention and treatment programs that asylum physicians employed to overcome mental illness, in addition to the victories and shortcomings of the system. Through this work, it will be shown that during the 1850s until the 1920s institutions faced difficulty in achieving success from many adverse conditions including, but not limited to, overcrowding, large geographical conditions, poor health practices, faulty construction, insufficient funding, ineffective prevention and treatment methods, disorganization, cases of patient abuse, incompetent employees, prejudice, and legal improprieties. As a result, by 1930, these asylums were merely places to detain the mentally ill in order to rid them from society. This thesis will also confirm that while both Texas politicians and mental health experts desired to address and overcome mental illness in Texas, they were …

Cultural Exchange: the Role of Stanislavsky and the Moscow Art Theatre’s 1923 and 1924 American Tours

The following is a historical analysis on the Moscow Art Theatre’s (MAT) tours to the United States in 1923 and 1924, and the developments and changes that occurred in Russian and American theatre cultures as a result of those visits. Konstantin Stanislavsky, the MAT’s co-founder and director, developed the System as a new tool used to help train actors—it provided techniques employed to develop their craft and get into character. This would drastically change modern acting in Russia, the United States and throughout the world. The MAT’s first (January 2, 1923 – June 7, 1923) and second (November 23, 1923 – May 24, 1924) tours provided a vehicle for the transmission of the System. In addition, the tour itself impacted the culture of the countries involved. Thus far, the implications of the 1923 and 1924 tours have been ignored by the historians, and have mostly been briefly discussed by the theatre professionals. This thesis fills the gap in historical knowledge.

Weeding Out the Undesirables: the Red Scare in Texas Higher Education, 1936-1958 (open access)

Weeding Out the Undesirables: the Red Scare in Texas Higher Education, 1936-1958

When the national Democratic Party began to transform to progressive era politics because of the New Deal, conservative reactionaries turned against the social welfare programs and used red scare tactics to discredit liberal and progressive New Deal Democrat professors in higher education. This process continued during the Second World War, when the conservatives in Texas lumped fascism and communism in order to anchor support and fire and threaten professors and administrators for advocating or teaching “subversive doctrine.” In 1948 Texas joined other southern states and followed the Dixiecrat movement designed to return the Democratic Party to its original pro-business and segregationist philosophy. Conservatives who wanted to bolster their Cold Warrior status in Texas also played upon the fears of spreading communism during the Cold War, and passed several repressive laws intended to silence unruly students and entrap professors by claiming they advocated communist doctrine. The fight culminated during the Civil Rights movement, when conservatives in the state attributed subversive or communist behavior to civil rights organizations, and targeted higher education to protect segregated universities. In order to return the national Democratic Party to the pro-business, segregationist philosophy established at the early twentieth century, conservatives used redbaiting tactics to thwart the …

Identifying Cultural and Non-cultural Factors Affecting Litter Patterns in Hickory Creek, Texas

Plastic deposition in hydrological systems is a pervasive problem at all geographic scales from loci of pollution to global ocean circulation. Much attention has been devoted to plastic deposition in marine contexts, but little is known about inputs of plastics into local hydrological systems, such as streams. Any attempt to prevent plastic litter must confront people’s behaviors, so archaeological concepts are used to distinguish between various cultural inputs (e.g., littering) and non-cultural forces (e.g., stream transport) that affect litter patterns on the landscape. Litter surveys along Hickory Creek in Denton, TX, are used to assess these factors.

Searching for Songs of the People: The Ideology of the Composers' Collective and Its Musical Implications (open access)

Searching for Songs of the People: The Ideology of the Composers' Collective and Its Musical Implications

The Composers' Collective, founded by leftist composers in 1932 New York City, sought to create proletarian music that avoided the "bourgeois" traditions of the past and functioned as a vehicle to engage Americans in political dialogue. The Collective aimed to understand how the modern composer became isolated from his public, and discussions on the relationship between music and society pervade the radical writings of Marc Blitzstein, Charles Seeger, and Elie Siegmeister, three of the organization's most vocal members. This new proletarian music juxtaposed revolutionary text with avant-garde musical idioms that were incorporated in increasingly greater quantities; thus, composers progressively acclimated the listener to the dissonance of modern music, a distinctive sound that the Collective hoped would become associated with revolutionary ideals. The mass songs of the two Workers' Song Books published by the Collective, illustrate the transitional phase of the musical implementation of their ideology. In contrast, a case study of the song "Chinaman! Laundryman!" by Ruth Crawford Seeger, a fringe member of the Collective, suggests that this song belongs within the final stage of proletarian music, where the text and highly modernist music seamlessly interact to create what Charles Seeger called an "art-product of the highest type."
