Miz Markley

Lisa Markley, a.k.a. "Miz Markley", is a genuinely happy person even if she is not particularly financially successful as a musician. In an effort to validate my own choices as an artist, I chose to follow her. What was intended to be a portrait of a working musician, becomes instead a feminist musical essay film about the transformative power of art making.

The Landscape Legacies of Gas Drilling in North Texas (open access)

The Landscape Legacies of Gas Drilling in North Texas

In North Texas, the Barnett Shale underlies large areas of the Dallas-Fort Worth Metroplex (DFW), which magnifies debates about the externalities of shale gas development (SGD). Continued demand for natural gas and expansive urbanization in DFW will cause more people to come in contact with drilling rigs, gas transport, and other urban shale gas landscapes. Thousands of gas wells within the DFW region occupy a large, yet scattered land surface area. DFW city planners, elected officials, and other stakeholders must deal with current and future urban growth and the surface impacts that are associated with gas development. This research examines how shale gas landscapes affect urban land uses, landscapes, and patterns of development in DFW. The study focuses on multiple fast growing DFW municipalities that also have high numbers of gas well pad sites. This study asks what are the spatial characteristics of gas well production sites in DFW and how do these sites vary across the region; how do gas well production sites affect urban growth and development; and how are city governments and surface developers responding to gas well production sites, and what are the dominant themes of contestation arising around gas well production sites and suburban growth?

A study of the impact of unconventional sources within a large urban area: evidence from spatio-temporal assessment of volatile organic compounds. (open access)

A study of the impact of unconventional sources within a large urban area: evidence from spatio-temporal assessment of volatile organic compounds.

Conventional sources of emissions have been a prime target for policymakers in designing pollution control strategies. However, the evolution of shale gas activities is a growing concern over the impact of unconventional sources on urban and regional air quality. Owing to the development of Barnett Shale production, the fast-growing Dallas-Fort Worth (DFW) metroplex has encountered both types of these emissions. Oil and gas activities result in emissions of ozone precursors, notably volatile organic compounds (VOC). The major objective of this study was to evaluate the spatio-temporal distribution of VOC in order to highlight the influence of unconventional emissions. The study utilized measurements from automated gas chromatography (AutoGC) monitors to analyze the patterns of the total non-methane organic compounds (TNMOC) and relative contributions from marker species of traffic versus oil and gas activities. In this study, data from 2001-2014 was obtained from the Texas Commission on Environmental Quality (TCEQ) for fifteen monitoring sites within the North Texas region. With over a thousand wells in a 10 mile radius, two of the rural sites measured twice as much TNMOC as compared to the urban site in Dallas. Source apportionment analysis was conducted using Positive Matrix Factorization (PMF) technique. The target site located …

Why Breastfeed? Understanding the Factors that Influence Women to Breastfeed in Southeast Fort Worth (open access)

Why Breastfeed? Understanding the Factors that Influence Women to Breastfeed in Southeast Fort Worth

Today breastfeeding is a common conversation with the ever-growing holistic movement and the effort to 'go green' as demonstrated by the proliferation of the organic food industry in recent years within the United States. Breastfeeding may reduce poor health outcomes including infant morbidity and mortality. Infant mortality is a priority in Tarrant County within southeast Fort Worth as defined by this project’s client Healthy Moms – Healthy Babies – Healthy Community. The purpose of this research was to identify the contextual factors that influence breastfeeding decisions among the zip codes in southeast Fort Worth in which infant mortality is greatest. In analysis of the data among breastfeeding mothers and stakeholders, support was the greatest contribution to successful breastfeeding.

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 …

Hurricane Storm Surge Sedimentation on the McFaddin National Wildlife Refuge, Texas: Implications for Coastal Marsh Aggradation (open access)

Hurricane Storm Surge Sedimentation on the McFaddin National Wildlife Refuge, Texas: Implications for Coastal Marsh Aggradation

This study uses the storm surge sediment beds deposited by Hurricanes Audrey (1957), Carla (1961), Rita (2005) and Ike (2008) to investigate spatial and temporal changes in sedimentation rates on the McFaddin National Wildlife Refuge in Southeast Texas. Fourteen sediment cores were collected along a transect extending from 90 to 1230 meters inland from the Gulf Coast. Storm-surge-deposited sediment beds were identified by texture, organic content, carbonate content, the presence of marine microfossils, and Cesium-137 dating. The hurricane-derived sediment beds are marker horizons that facilitate assessment of marsh sedimentation rates from nearshore to inland locations as well as over decadal to annual timescales. Near the shore, on a Hurricane Ike washover fan, where hurricane-derived sedimentation has increased elevation by up to 0.68 m since 2005, there was no measurable marsh sedimentation in the period 2008-2014. Farther inland, at lower elevations, sedimentation for the period 2008-2014 averaged 0.36 cm per year. The reduction in sedimentation in the period 2008-2014 on the nearshore part of the marsh is likely due to reduced flooding in response to increased elevation from hurricane storm surge sediment deposition. These results provide valuable knowledge about the sedimentary response of coastal marshes subject to storm surge deposition and …

Addressing Social Elements of Wildfire: Risk, Response, and Recovery in Highland Village, TX (open access)

Addressing Social Elements of Wildfire: Risk, Response, and Recovery in Highland Village, TX

Representatives of the City of Highland Village expressed concern over the risk of wildfires for their community. Anthropology provides many tools for and examples of disaster assessment of preparedness, response, recovery, and mitigation. These tools combined with Geographic Information Systems (GIS) can provide a holistic, cultural ecological look at how such a disaster may take place in the city. The project's methods included a detailed survey of preparedness steps which was analyzed using SPSS and also imported into ArcGIS for spatial analysis, and semi-formal, in-depth interviews with residents of the community regarding preparedness, response, and recovery. Residents fell into a middle category of preparedness, with the majority of participants considering or implementing a few recommended preparedness steps. Interview participants expressed respect for and trust of the city and first-responders, as well as a willingness to volunteer their help during response and recovery stages. Finally the American Community Survey showed that resident socioeconomic vulnerability was considerably low, and no action needed to be taken to advocate for at-risk individuals. Overall, the City of Highland Village showed a high resiliency to disaster. A wildfire likely will not have a major impact on the community as a whole, though the city may reduce …

Field Validation of Zero Energy Lab Water-to-Water Ground Coupled Heat Pump Model (open access)

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 …

Analyzing Tuberculosis Vulnerability and Variables in Tarrant County (open access)

Analyzing Tuberculosis Vulnerability and Variables in Tarrant County

Over 9 million new cases of tuberculosis (TB) were reported worldwide in 2013. While the TB rate is much lower in the US, its uneven distribution and associated explanatory variables require interrogation in order to determine effective strategies for intervention and control. However, paucity of case data at fine geographic scales precludes such research. This research, using zip code level data from 837 confirmed TB cases in Tarrant County obtained from Texas Department of State Health Services, explores and attempts to explain the spatial patterns of TB and related risk markers within a framework of place vulnerability. Readily available census data is then used to characterize the spatial variations in TB risk. The resulting model will enable estimations of the geographic differences in TB case variables using this readily available census data instead of time-consuming and expensive individual data collection.

Performance Evaluation of UNT Apogee Stadium Wind Turbines (open access)

Performance Evaluation of UNT Apogee Stadium Wind Turbines

The following report chronicles the University of North Texas Wind Turbine Project at Apogee Stadium. The timeline of events will include the feasibility study conducted by and for the university, grant awards from the Texas State Energy Conservation Office to fund the project, and a three-year sample of real time performance data since installation. The purpose of this case study is to compare the energy generation estimates by various stakeholders to the measured energy generation using a new but uniform performance relationship. In order to optimize energy generation in wind turbine generator systems, the most common wind speeds measured at the site should also be the most efficient wind speeds at which the wind turbine can convert the kinetic energy in the wind into mechanical energy and ultimately electrical energy. The tool used to convey this relationship will be a figure plotting the wind speed profile against the efficiency curve of the wind turbine. Applying this relationship tool to the UNT Apogee Stadium wind turbines provided valuable results. The most common wind speeds at Apogee Stadium are not the most efficient wind speed for the turbine. Also, the most common wind speeds were near the lower limit of the wind …

Memory and Continuity Amidst Irreversible Decline in the Texas Big Empty (open access)

Memory and Continuity Amidst Irreversible Decline in the Texas Big Empty

This thesis interrogates sense of place and place attachment in the Big Empty on the north central Texas plains. The region stretches from the Red River on the north to the Colorado River basin on the south and from the Cross Timbers on the east to the Caprock escarpment on the west. Since 1930, the Big Empty has seen sustained and severe population decline such that some counties there now register less than a quarter the population they did at their peaks during the interwar years. Through in-depth field interviews, I examine sense of place and place attachment amidst apparently irreversible decline. I also describe conditions of postindustrial rurality arising from rolling reconfigurations of economic and social relations, particularly changes in scale in farming and the diminished centrality of productivist agriculture in local economies and culture, and how these conditions become legible through the study of place.

The Great Hanging (open access)

The Great Hanging

"The Great Hanging" is a documentary film that tells the story of the largest extra-legal mass hanging in U.S. History. This story is told through stage play recital of "October Mourning" written by historian and professor Dr. Pat Ledbetter. Using the stage play as a vehicle, the film showcases cinematic re-enactments based in the events in Gainesville, Texas during October 1862. These events show how a small community became overwhelmed by the fog of war and delved into madness as the Civil War crept closer and closer to their doorstep.

Forgotten Legacies: The U.S. Glider Pilot Training Program and Lamesa Field, Texas, During World War II

Rapidly initiated at the national, regional, and local levels, the American glider pilot training program came about due to a perceived need after successful German operations at the outset of World War II. Although the national program successfully produced the required number of pilots to facilitate combat operations, numerous changes and improvisation came to characterize the program. Like other American military initiatives in the twentieth century, the War Department applied massive amounts of effort, dollars, and time to a program that proved to be short-lived in duration because it was quickly discarded when new technologies appeared. At the local level, the real loser was Lamesa, Texas. Bearing the brunt of these changes by military decision makers, the citizens of Lamesa saw their hard-fought efforts to secure an airfield fall quickly by the wayside in the wake of changing national defense priorities. As generations continue to pass and memories gradually fade, it is important to document and understand the relationship between this military platform that saw limited action and a small Texas town that had a similarly short period of significance to train the pilots who flew the aircraft.

The Walling Family of Nineteenth-Century Texas: An Examination of Movement and Opportunity on the Texas Frontier

The Walling Family of Nineteenth-Century Texas recounts the actions of the first four generations of the John Walling family. Through a heavily quantitative study, the study focuses on the patterns of movement, service, and seizing opportunity demonstrated by the family as they took full advantage of the benefits of frontier expansion in the Old South and particularly Texas. In doing so, it chronicles the role of a relatively unknown family in many of the most defining events of the nineteenth-century Texas experience such as the Texas Revolution, Mexican War, Civil War, Reconstruction, and the Close of the Frontier. Based on extensive research in census, tax, election, land, military, family paper, newspaper, and existing genealogical records; the study documents the contributions of family members to the settlement of more than forty counties while, at the same time, noting its less positive behaviors such as its open hostility to American Indians, and significant slave ownership. This study seeks to extend the work of other quantitative studies that looked at movement and political influence in the Old South, Texas, and specific communities to the microcosm of a single extended family. As a result, it should be of use to those wanting a greater …
