Item A long quavering chant : peonage labor camps in the rural-industrial South, 1905-1965(2013-05) Reynolds, Aaron Kyle; Jones, Jacqueline, 1948-; Bsumek, Erika; Sidbury, James; Falola, Toyin; Bremen, BrianThis dissertation is a study of social and environmental conditions inside rural industrial labor camps throughout the U.S. South between 1905 and 1965. The use of peonage labor, i.e., the coercion of labor against ones’ will through indebtedness or violence impacted nearly a fourth of rural workers in the postbellum south, particularly in isolated railroad construction sites, lumber operations, turpentine camps, and commercial vegetable farms. Though employers’ various peonage labor regimes changed within the context of the camps’ physical environment and evolved over time, they continually took advantage of marginalized social groups, immigrants, African-Americans, and the poor. The relative inability of workers, their families, and reformers to prosecute employers and foremen for labor abuses stemmed from the collusion of local law enforcement and the indifference of federal government officials. Ultimately, broader market forces of globalization and technology changed peonage labor regimes, not the enforcement of federal statues outlawing the practice.Item The African American college football player : a holistic exploration of identity, challenges and environment(2012-05) Miller, I Shujaa Keino; Cokley, Kevin O. (Kevin O'Neal), 1969-College football is big business, earning slightly more than $1 billion in profit in the last few years. As a result of its popularity, fans of the game devour massive amounts of information about college teams and their players. Less known are the non-academic challenges college football players face, in addition to the typical concerns shared with their non-athletic peers. Along with academic and cognitive challenges, the ability to effectively navigate non-academic areas - such as personal, social and cultural - is critical to the development and holistic growth of today’s college football players. These factors can affect a student's ability to thrive or persist toward graduation. In this report, I explore the specific challenges of African American college football players at predominantly White institutions. Within this scope, I will examine the growth of college football in addition to the reach and impact it has on African American families. Within these communities, research shows a pervasive focus on playing professional football. Some players believe that college football is a mere stepping stone on the road to a professional career. The reality is that very few college football players are chosen to play professionally – actually less than .2%. This report explores some of the psychosocial issues that can impact the on and off the field success of African American college football players at predominantly White institutions The goal of this work is to lay a foundation and make an argument for counseling and therapeutic support targeted to, but not exclusively for African American college football players. As systems that seek to understand growth and change for optimum mental and physical well-being, the field of counseling and sports psychology present intervention models that can be useful for today’s African American college football players.Item American wasteland : a social and cultural history of excrement, 1860-1920(2012-05) Gerling, Daniel Max; Davis, Janet M.; Engelhardt, Elizabeth D.; Hartigan, John; Meikle, Jeffrey L.; Smith, Mark C.Human excrement is seldom considered to be an integral part of the human condition. Despite the relative silence regarding it, however, excrement has played a significant role in American history. Today the U.S. has more than two million miles of sewer pipes underneath it. Every year Americans flush more than a trillion gallons of water and fertilizer down the toilet, and farmers spend billions of dollars to buy artificial fertilizer. Furthermore, excrement is bound up in many complicated power relationships regarding race, gender, and ethnicity. This dissertation examines the period in American history, from the Civil War through the Progressive Era, when excrement transformed from commodity to waste. More specifically, it examines the cultural and social factors that led to its formulation as waste and the roles it played in the histories of American health, architecture, and imperialism. The first chapter assesses the vast changes to the country’s infrastructure and social fabric beginning in the late nineteenth century. On the subterranean level, much of America’s immense network of sewers was constructed during this era—making it one of the largest public works projects in U.S. history. Above ground, the United States Sanitary Commission, founded at the onset of the Civil War, commenced a widespread creation of sanitary commissions in municipalities, regions, and even internationally, that regulated defecation habits. Chapter Two assesses the social and architectural change that occurred as the toilet moved from the outhouse to inside the house—specifically, how awkwardly newly built homes accommodated this novel room and how the toilet’s move inside actually hastened its removal. The third chapter shifts focus to the way Americans considered their excrement in relation to their body in a time when efficiency a great virtue. Americans feared ailments related to “autointoxication” (constipation) and went to absurd lengths to rid their bodies of excrement. The fourth chapter analyzes the way excrement was racialized and the role it had in the various projects of American imperialism. The colonial subjects and potential American citizens—from Native Americans to Cubans, Filipinos, and Puerto Ricans—were regularly scrutinized, punished, and re-educated regarding their defecation habits.Item An alternative environmentally benign process for printed circuit board recycling(Texas Tech University, 2006-05) Ouyang, Xi; Zhang, Hong-Chao; Li, Guigen; Rivero, Iris V.; Smith, Milton L.; Collins, Terry R.In recent years there has been increasing concern about the growing volume of end-of-life electronic products. As the primary elements in most electronic products, Printed Circuit Board (PCB) is widely used and its recycling becomes a challenge not only to the industry, but also to the society. As an alternative environmentally benign method for PCB recycling, this dissertation adopts a novel processing method to separate the PCB scraps, which would increase the recycling rate and reduce the negative environment impact. Various solvent systems, i.e., carbon dioxide and water, are explored for delaminating PCB scraps at certain high temperature and pressure. For the purpose of finding an optimal condition for PCB delaminating, the experiment facilities were set up at the Advanced Manufacturing Lab (AML) in the Department of Industrial Engineering. Through series designed experiments, input parameters such as temperature, pressure and process time were recorded, and the output parameters, i.e., weight reduction, thickness expansion, impact energy variation were measured to evaluate the PCB delaminating results. Response Surface Method (RSM) was applied for selecting the input parameters. Multiple Objective Optimization method (MOO) was adopted to evaluate the overall delaminating effects. The utility theory was utilized to set up the utility function and figure out the optimal solution. Furthermore, the fundamental mechanism which caused the epoxy resin decomposing was interpreted. The explanation was helpful for selecting various solvents to speed up the reaction and improve the efficiency. In this research, the effectiveness of the alternative method to delaminate waste PCB scraps, that is, utilization of the chemical process was examined. Based on this method, series experiments were designed and implemented to search for an optimal condition. Through the output data analysis, optimization process conditions were determined. Consequently the reaction mechanism was interpreted. Some other solvent systems were tested to hasten the reaction speed, i.e., ternary solvent system of carbon dioxide, water, and ethanol. This alternative printed circuit board recycling process is promising for industrialization in the future.Item An alternative environmentally benign process for printed circuit board recycling(2006-05) Ouyang, Xi; Zhang, Hong-Chao; Collins, Terry R.; Li, Guigen; Rivero, Iris V.; Smith, Milton L.In recent years there has been increasing concern about the growing volume of end-of-life electronic products.

Theoretical foundations are based on the work of Karl Manheim concerning generations and supplemented by ecofeminist theory to aid in the formation of research hypotheses. Using three scales as measures of environmental attitudes, environmental threat perception, activism, and material sacrifice, research questions are posed to examine the possible existence of generational differences. Additionally, demographic variables are included and research questions posed based on their relationship to environmental attitudes. The outcome of this work will contribute to a greater understanding of multi-generational trends in environmental attitudes that have occurred, and are continuing to develop, in relation to demographic and ideological variables.Item Animal kingdoms : princely power, the environment, and the hunt in colonial India(2009-12) Hughes, Julie Elaine; Minault, Gail, 1939-; Talbot, Cynthia; Davis, Janet; Hyder, Syed Akbar; Louis, William Roger; Charlesworth, MichaelShaped in part by diverse landscapes, game profiles, and ruling personalities, hunting in the Indian princely states in the colonial period was heterogeneous to a previously unrecognized extent. At the same time, significant underlying political, social, and cultural continuities unified states and their rulers’ approaches to sport. Focusing on the Rajput realms of Mewar, Orchha, and Bikaner, I show how princes of different ranks negotiated their states’ divergent landscapes in pursuit of dissimilar game, and how they trusted in superior hunting grounds, wildlife, and shooting methods to advance their personal standings and sovereign powers. I also investigate how these rulers used hunting to maintain connections with their state and lineage histories, to exemplify local Rajput ideals and identities, and to manage relationships with various audiences, including their subjects, state nobles, other princes, and British officials. This study is concerned as much with princely perceptions of game and shooting grounds as with “real” landscapes or environmental changes. I examine how the princes conceptually linked natural abundance with favorable political conditions and degradation with lost power and compromised dignity. I consider what it meant to pursue tigers, wildfowl, antelope, and wild boar in dense jungles, wetlands, arid plains, and imposing hills. In addition, I look at the ways princes attempted to employ and also to modify those meanings to suit their own purposes. I did the research for this dissertation at government and private archives in India and the United Kingdom. Because my primary goal was to discover princely views, I relied as far as possible on sources produced by elite Indians or by those in their service. Among the materials I used were state government records, personal correspondence, speeches, game diaries, hunting memoirs, photographs, and miniature paintings. Much of the documentation was in English, with the major exception of records relating to Mewar State and its subordinate noble estates. The language of those papers ranged from Hindi through Rajasthani (Mewari). To understand British responses better, I consulted Government of India records. Published memoirs and travelogues written by Europeans who visited and hunted in the regions under consideration also proved useful.Item Cancer Alley and infant mortality : is there a correlation?(2011-12) Kluber, Heidi Ellen; Eaton, David J.; Sletto, BjornThis report explores issues surrounding health concerns in the State of Louisiana in the context of environmental justice. It provides a history of Cancer Alley, an area along the Mississippi River with disproportionately high cancer rates. It discusses case studies of environmental justice issues within the state. The researcher provides a geographical analysis and statistical analysis to estimate whether there is a relationship between the presence of industrial plants and health indicators, specifically cancer and infant mortality. Using cancer and infant mortality as health indicators for a population, the evidence supports a correlation between the presence of industrial pollution and waste with cancer rates and infant mortality rates across the State of Louisiana. Given that these populations are predominantly minority and low-income, these results reflect an environmental injustice.Item Coding sustainable neighborhoods : a comparative analysis of LEED for neighborhood development and the healthy development measurement tool(2012-12) Niswonger, Jean Louise Yano; Moore, Steven A., 1945-; Sletto, Bjørn INeighborhood design has a significant impact on environmental and human health and is largely regulated by the codes developed by various professional organizations. While the sustainability movement as a whole has embraced the mutually beneficial goals of improving environmental and human health, the work of professionals in the environmental and public health fields has remained largely segregated over the past century. The purpose of my thesis is to compare the approach of each field in fostering sustainable neighborhoods through the development and implementation of codes and to quantify both the existing degree of collaboration and the latent potential for further collaboration within these codes. For comparison, I selected LEED for Neighborhood Development and the Healthy Development Measurement Tool to be representative of neighborhood codes generated by the environmental and public health movements, respectively, because they are the most fully developed and widely implemented evaluation systems presently available in each field. In order to investigate how the codes generated in each field compare in their approach, structure, and organization, I first performed a comparative analysis between them. I then performed a content analysis on both codes to quantify the overlap in goals between them. My hypothesis was that each field would exhibit a bias towards goals which explicitly support their own field, but that a significant portion of their goals would simultaneously support the other field. This hypothesis proved to be correct, but most interesting was the significant percentage of shared goals that were left unexpressed. Ultimately, 94% of recommended actions in LEED-ND were related to human health, though it was only explicitly referenced in 25% of the code. Similarly, 74% of recommended actions in the HDMT were related to environmental health, though it was only explicitly mentioned in 33% of the code. My thesis demonstrates that, while both fields already recognize that a small portion of their goals are shared, it is actually likely that nearly all of their goals are shared. By actively acknowledging these shared goals, both fields can potentially benefit from the greater amount of support, resources, and expertise that would become available to them through collaboration.Item Creating a sustainable preservation hybrid in post-Katrina New Orleans(2009-05) Stanard, Lorna Michelle; Holleran, MichaelThe two fields of historic preservation and sustainable design include many similar values concerning conservation, yet produce buildings that ultimately look and perform differently. Historic preservation relies on the maintenance of traditional materials to ensure that historic buildings are preserved for future generations. Sustainable design typically works with new construction to create buildings that have little negative impact on the environment. The similarities yet separateness that exist between historic preservation and sustainable design provide a compelling platform to ask how we can combine the two fields within one building project. The combination of these two felds is currently being explored in post-Katrina New Orleans, and I am asking how we can combine historic preservation with aspects of sustainable design to create a sustainable preservation hybrid, or fusion between technological aspects of “green” design with traditional methods of preservation, that will allow historic buildings to maintain their integrity and achieve the values of sustainability. New Orleans provides a great opportunity to examine this question due to the damage caused by Hurricane Katrina and the ensuing efforts to rebuild the city. One specific area of New Orleans, the historic district of Holy Cross, plays home to two key organizations involved in the rebuilding: the Preservation Resource Center, which preserves the existing historic housing stock, and Global Green, which builds new, sustainable design projects. These two organizations work right down the street from one another, yet have yet to combine their building methods or work together on a shared project. This relationship between Global Green/sustainable design and the Preservation Resource Center/historic preservation provides a good opportunity to examine how elements of new sustainable design can be combined with the traditional methods of preservation in order to achieve a sustainable preservation hybrid. I examine the creation of a sustainable preservation hybrid by conducting a literature review, interviews and site visits, and energy modeling. The literature review reveals that preservationists and architects involved with sustainable design like the idea of creating a hybrid, but still lack a thorough understanding of each other’s tacit values. The interviews reveal how the organizations working in Holy Cross also embrace the idea of a sustainable preservation hybrid, yet remain somewhat lost as to how to actually create such a building. The energy modeling then demonstrates which combination of “green” materials from sustainable design and “traditional” materials from historic preservation combine to create a building that achieves both the values of sustainable design and historic preservation. Whether or not we can combine preservation and sustainable design to make a hybrid poses an original and relevant question in the context of post-Katrina New Orleans and elsewhere. Since we are currently facing an energy crisis, the conclusions as to how we can combine these two fields prove how a single, historic building can simultaneously conserve both environmental and historic resources.Item Culture shock : tales from the 21st century intentional community movement(2012-05) Bathurst, Stephanie Marie; Minutaglio, Bill; Darling, Dennis CarlyleIn the wake of the Great Recession of 2008, the ‘new normal’ left many Americans deflated after losing their financial savings and general confidence in the political system. There is a growing movement saying the traditional path to the American Dream is no longer satisfying. From coast to coast families are moving from sleepy towns to so-called ‘intentional communities’ in search of alternatives. They are building new lives in spiritual enclaves, nudist havens, eco-wonderlands and other unorthodox societies while seeking like-minded souls and a better way of making a living. Although they don’t often reflect the traditional lifestyle of most citizens, they do represent the widespread frustration with the status quo. The United States has long been a safe haven for these nonconformists and continues to attract those seeking escape from the mainstream each year. Intentional communities throughout Texas and the U.S. are flourishing despite harsh economic times elsewhere. This report documents daily life in three intentional communities during 2011 and 2012, all focused on achieving their individual goals of environmental protection, building community bonds, and achieving spiritual enlightenment.Item Designing a Real-time Strategy Game about Sustainable Energy Use(2011-08-08) Doucet, Lars AndreasThis thesis documents the development of a video game about sustainable energy use that unites fun with learning. Many other educational games do not properly translate knowledge, facts, and lessons into the language of games: mechanics, rules, rewards, and feedback. This approach differs by using game mechanics in new ways to express lessons about energy sustainability. This design is based on the real time strategy (RTS) genre. Players of these types of games must manage economic problems such as extracting, refining, and allocating resources, as well as industrial problems such as producing buildings and military units. These games often use imaginative fantasy elements to connect with their audience, but also made-up economic numbers and fictional resources such as magic crystals which have little to do with the real world. This thesis' approach retains the fantasy elements and gameplay conventions of this popular genre, but uses numbers, resources, and situations based on research about real-world energy production. The intended result is a game in which the player learns about energy use simply by trying to overcome the game's challenges. In addition, a combined quantitative/qualitative study was performed, which shows that players of the game learned new things, enjoyed the game, and became more interested in the topic of energy use.Item Effect of flue gas impurities on the process of injection and storage of carbon dioxide in depleted gas reservoirs(Texas A&M University, 2005-11-01) Nogueira de Mago, Marjorie CarolinaPrevious experiments - injecting pure CO2 into carbonate cores - showed that the process is a win-win technology, sequestrating CO2 while recovering a significant amount of hitherto unrecoverable natural gas that could help defray the cost of CO2 sequestration. In this thesis, I report my findings on the effect of flue gas ??impurities?? on the displacement of natural gas during CO2 sequestration, and results on unconfined compressive strength (UCS) tests to carbonate samples. In displacement experiments, corefloods were conducted at 1,500 psig and 70??C, in which flue gas was injected into an Austin chalk core containing initially methane. Two types of flue gases were injected: dehydrated flue gas with 13.574 mole% CO2 (Gas A), and treated flue gas (N2, O2 and water removed) with 99.433 mole% CO2 (Gas B). The main results of this study are as follows. First, the dispersion coefficient increases with concentration of ??impurities??. Gas A exhibits the largest dispersion coefficients, 0.18-0.25 cm2/min, compared to 0.13-0.15 cm2/min for Gas B, and 0.15 cm2/min for pure CO2. Second, recovery of methane at breakthrough is relatively high, ranging from 86% OGIP for pure CO2, 74-90% OGIP for Gas B, and 79-81% for Gas A. Lastly, injection of Gas A would sequester the least amount of CO2 as it contains about 80 mole% nitrogen. From the view point of sequestration, Gas A would be least desirable while Gas B appears to be the most desirable as separation cost would probably be cheaper than that for pure CO2 with similar gas recovery. For UCS tests, corefloods were conducted at 1,700 psig and 65??C in such a way that the cell throughput of CO2 simulates near-wellbore throughput. This was achieved through increasing the injection rate and time of injection. Corefloods were followed by porosity measurement and UCS tests. Main results are presented as follows. First, the UCS of the rock was reduced by approximately 30% of its original value as a result of the dissolution process. Second, porosity profiles of rock samples increased up to 2.5% after corefloods. UCS test results indicate that CO2 injection will cause weakening of near-wellbore formation rock.Item Effects of Heat Stress and Increased Protein Fed in Milk Replacers on the Health and Growth Parameters of Neonatal Holstein Bull Calves(2012-10-19) Krenek, AndrewObjectives of the study were to evaluate if calves fed 6 L of high protein milk replacer (HPMR; 1135 g/d, 28% crude protein (CP), 20% fat) had improved performance and health as compared to calves fed 4 L of a conventional milk replacer (CMR; 454 g/d, 20% CP, 20% fat) in heat stress and non heat stress environments. Holstein bull calves (n=52) <3 d of age were assigned to a 2 x 2 factorial trial based on initial BW, physical health score, and total serum protein levels. One half of each nutrition group was housed indoors with temperature control, non-heat stress (NHS) environment and one half was housed outside under a shaded barn in subjecting them to a heat stress (HS) environment. The study was conducted for 56 d from June 18 to August 13, 2010. Average thermal heat index (THI) was calculated for each day using the average of 24 recorded temperatures and relative humidity (RH%). The 56 d average, low, and high range THI for the HS was 79, 67, and 86, respectively, while THI for the NH was 69, 66, and 74, respectively. Weekly measurements of body weight (BW) in kg, body length (BL), hip width (HW), wither height (WH), heart girth (HG), and hip height (HH) in cm were collected and average daily gain (ADG) was calculated. Water consumption (WC) in mL and starter intake (SI) in grams was measured daily. Feed conversion (FC) was also calculated for each nutritional treatment and environment. Fecal scores (FS) of 1 to 4 (1=hard, firm, 2=soft, firm, 3=no form, and 4=watery) were recorded daily. Calves with a FS of >3 were considered to have diarrhea and required treatment. Respiration rates (RR) were recorded at 0630 (AM) and 1830 (PM) to monitor respiratory challenges while rectal temperatures (RT) were also measured using a digital thermometer daily in AM and PM to monitor febrile events. If RT was greater than 39.2 degrees C for NHS calves and 39.7 degrees C for HS calves, they were treated for febrile events (FE). Data was analyzed using PROC MIXED (SAS 9.2). HPMR had a greater (P < 0.01) WH, HG, BL, HH, ADG, WC, and FS than the CMR (0.15 vs. 0.11, 0.37 vs. 0.28, 0.27 vs. 0.22, 0.21 vs. 0.14, 0.82 vs. 0.58, 4235 vs. 2656, and 2.05 vs. 1.73, respectively). HS had a greater (P < 0.01) WC than NHS (4365 vs. 2526, respectively). CMR had a greater SI and FC (P < 0.05) than HPMR (0.942 vs. 0.437, and 1.99 vs. 1.78, respectively). HS had a higher RT AM, RT PM, RR AM, and RR PM (P<0.01) than NHS (38.87 vs. 38.77, 39.03 vs. 38.79, 35.79 vs. 32.77, and 55.73 vs. 38.57, respectively. Calves in NHS had a higher FE (P<0.01) than the HS calves (6.24 vs. 2.33). There was no significant difference in growth parameters in HS or NHS in calves of like feeding strategies. The results show calves in HS experienced higher RT AM, RT PM, RR AM, and RR PM. The increased protein and energy fed to the HPMR calves resulted in greater FS and increased growth.Item Enzymatic inhibition-based biosensing on nitrogen-doped carbon nanotube electrodes(2015-05) Rust, Ian Matthias; Stevenson, Keith J.; Webb, Lauren JWhile previous work has demonstrated the effectiveness of nitrogen-doped carbon nanotubes (N-CNTs) as biogenic electrode materials in first- and second-generation biosensors, this thesis primarily explores enzymatic inhibition-based biosensing schemes on N-CNT electrodes. This type of scheme enables the detection of enzymatic inhibitors, as opposed to enzymatic substrates, making these inhibition-based biosensors much more suitable for the monitoring of environmental pollutants. Presented in this thesis is a biosensor which couples N-CNTs with glucose oxidase (GOx) through spontaneous physical adsorption for the highly sensitive detection of aqueous silver ions. Included is a thorough discussion of the parameters that affect response time as well the biosensor’s aptitude for repeated use. A later chapter presents initial work towards the inhibition-based detection of sucralose, a relatively new environmental pollutant. A bi-enzymatic approach is explored, in which both GOx and invertase are immobilized on an N-CNT modified electrode. Finally, shifting focus from inhibition-schemes, the last remaining chapter investigates the coupling of CNTs and N-CNTs with methylene green (MG), a redox mediator used in second-generation biosensors based on NADH oxidation. Common coupling techniques are examined for their effectiveness in decreasing the overpotential required for NADH oxidation.Item Essays on environmental and public economics(2011-05) Monti, Holly Anne Odell; Williams, Roberton C., 1972-; Hamermesh, Daniel S.; Abrevaya, Jason; Fullerton, Don; Trejo, StephenThis dissertation is a collection of three essays in the fields of environmental and public economics. The first essay assesses the effect of government spending on charitable donations to environmental causes. Using a theoretical model, I solve for changes in private donations due to increased government spending and contrast this with changes due to direct grants to nonprofit organizations. Depending on the nonprofit’s fundraising response, government spending may result in the crowding out or in of private giving. I empirically investigate this topic using data from the tax returns of environmental charities as well as a panel survey data set on the philanthropic behavior of individuals. My results indicate that government expenditures on the environment actually crowd in private giving, partly due to the increased fundraising response by charities. The second essay examines the incidence of a pollution tax scheme in which tax revenue is returned to low-income workers. Using a general equilibrium model with both skilled and unskilled labor, a decomposition of the real net wage effects shows the effect of the tax rebate, the effect on the uses side of income (higher product prices), and the effect on the sources side of income (relative wage rates). Numerical examples show that returning the revenue to the low-skilled workers is still not enough to offset the effect of higher product prices; in almost all cases, the rebate does not prevent a reduction in the real net wage. The third essay studies the distributional effects of the SO2 allowance market. Even if low-income households do not have large budget shares for the polluting good, grandfathered permit systems may still be regressive since the permit rents accrue disproportionately to wealthy shareholders in the polluting industry. I estimate the burden imposed on different income groups under a grandfathered permit policy and compare this with the burden under an auctioned policy. Using Monte Carlo techniques, I calculate the 5th and 95th percentiles of the distribution of possible results. I find evidence of regressivity for grandfathered permits whereas an emissions tax/auctioned permit system can be progressive if the scarcity rents are distributed in lump sums.Item Evaluating Environmental Impact Assessment of a local land use plan : a case study of the City of Elk Grove’s general plan EIRs(2008-12) Jung, Seung Hoon; Paterson, Robert G.Many planners and researchers pay attention to the potentials of Environmental Impact Assessment (EIA) as a planning method. The EIA of a local land use plan or comprehensive plan becomes effective under the Mini-NEPA or State Environmental Policy Act. In this context, this study focuses on the NEPA based EIA of local land use plans in order to examine its effectiveness as part of the planning process. Based on the assumption that systematic environmental assessment will ensure the effectiveness and the quality of a local land use plan, this study evaluate a local land use plan EIA process of California with the quality and effectiveness criteria.Item From chaos to harmony : public participation and environmental policy(2011-12) Dulay, Marcel; Eaton, David J.; Rodriguez, Victoria E.; Spelman, William G.; Browning, Larry D.; Maxwell, Madeline M.Water quality issues in the Leon River watershed in Texas exemplify the challenges water resource managers and the public face in the ongoing effort to improve water quality in our nation’s water bodies. Some pollutant sources are difficult to regulate and likely managed through non-regulatory means, such as voluntary action. The Leon River challenge is how to go beyond regulations to address the concerns of citizens and produce options they want to develop and implement voluntarily that address a common good. This dissertation argues that voluntary measures work only if those who must take action support the action, otherwise conflict can occur. Thus, it is critical to learn what people are willing to do to promote the public good (e.g., swimmable streams). This can be achieved through an effective public process. Public participation processes may have barriers that impede success, such as inadequate access, intimidation, competing interests, limited accountability, and scientific mistrust. This dissertation developed process enhancements to overcome these barriers based on documented public participation principles. This research tested whether specific enhancements can improve the quality of a public process and achieve desired process outcomes. This dissertation reports on quasi-experiments with stakeholders making actual environmental decisions. The findings suggest that these enhancements are capable of reducing conflict and reducing the time to produce environmental policy. Five process enhancements (representation, film, narratives, deliberative decision-making, and decision support) were put into operation to provide options for government agencies and stakeholders to consider when undertaking public participation processes. The lack of access can be avoided by giving stakeholders voice with representation through different types of meetings levels (e.g., focus groups and town hall meetings). Films, when captured, edited, and shown to others, can remove the mechanisms typically associated with the intimidation perceived by speakers during discussions. Narratives were used to collect information about stakeholders to develop a deeper understanding of the diversity of interests affected by a policy, avoiding gridlock from positional bargaining. Deliberative decision-making (no voting) can assure stakeholders have real and equitable decision-making power, with scenarios collaboratively developed that address the common good. Application of a decision support system (DSS) as an overlay to a scientific model can provide stakeholders direct access to science so they can develop scenarios, evaluate alternatives, and choose solutions.Item Going green : sustainable mining, water, and the remaking of social protest in post-neoliberal Ecuador(2012-12) Velásquez, Teresa Angélica; Hale, Charles R., 1957-; Ghosh, Kaushik; Sawyer, Suzana; Speed, Shannon; Vargas, Joao HThis dissertation examines the reconfiguration of popular environmental politics in the context of so-called sustainable mining development in Ecuador. Progressive governments in Latin America herald sustainable mining initiatives as the lynchpin to development capable of generating revenues to finance social welfare programs and protecting the environment. If this is so, my dissertation asks, then why has a proposed sustainable gold mine provoked such bitter opposition from dairy farmers in the parish of Victoria del Portete? My dissertation follows a group of indigenous and mestizo dairy farmers in the southern Ecuadorian Andes to understand why they oppose gold mining in their watershed and traces the cultural and political transformations that followed from their activism. I make four key arguments in this dissertation. First, I argue that sustainable mining plans place a premium on local water resources and have the effect of rearticulating local water disputes. Whereas owners of small and large dairy farms have historically disputed local access to water resources now they have created a unified movement against the proposed gold mine project. Second, I argue that knowledge practices and political discourses enabled farmers with varying claims to ethnic ancestry and socio-economic standing to establish connections with each other and with national indigenous leaders, Catholic priests, artists, and urban ecologists. Together they have formed a movement in defense of life. My analysis extends common understandings of the nature of human agency and political life by examining the role that non-human entities play in shaping contemporary environmental politics. Third, as a result of the mobilizations, new socio-environmental formations have emerged. The watershed has become a sacred place called Kimsacocha, which is venerated by farmers through new cultural practices as the source of life. Finally, the mobilizations in defense of life have re-centered indigeneity in unexpected ways. Farmers with and without indigenous ancestry as well as their urban allies are now claiming an indigenous identity. Unlike previous understandings of identity in the region, indigeneity does not denote a shared racial, cultural, or class position but refers to a particular way of understanding and relation to the environment.Item Grassland frontiers:beef cattle agriculture in Queensland and Texas, 1870s - 1970s(Texas Tech University, 2008-05) Turner, Leland K.; Carlson, Paul H.Semi-arid, but apparently lush, grasslands attracted pastoral settlers in the late nineteenth century to the frontier fringes of the Australian interior and American Southwest. Pastoral settlers and beef growers, particularly in Queensland and Texas, occupied similar environmental landscapes and shared a value system that embraced European informed agricultural production. In response to international market demand, beef growers set about transforming their natural landscapes. Beef producers drilled for artesian water, diverted surface waters, introduced exotic grasses, and exterminated native wildlife in a drive to produce ever more beef. They petitioned government to provide and/or subsidize transport to market and to expand market limitations through chilling and eventually refrigeration technology. Nature was not so easily held hostage to the economic prerogatives of beef producers. Babesiosis, Texas Fever in the vernacular, an often fatal disease in cattle and crippling drought challenged beef production in both Queensland and Texas. Persistent environmentally-driven difficulties led cattlemen in their quest on both continents to take dominion over arid lands to once again pursue scientific answers to continuing economic dilemmas. In an era when agriculturalists were devoted to scientific inquiry, cattlemen began, principally in Texas, to develop breeds that could endure harsh environmental conditions and produce marketable beef. In time, particularly in Queensland, many Australians adapted their breeding practices to the realities of their environment. Economic difficulties caused many to embrace uniquely Texas-born solutions to shared problems—Texas Fever and challenging rangeland environs. It was a biological response to difficult environmental conditions and disease. Nonetheless, a certain comfort level with traditional agricultural practices, cultural mores, and identity constructs sustained an Australian resistance to “mongrel” cattle breeds of American origin. Australian cattle raisers, intent on maintaining their “Britishness,” clung to English cattle breeds despite heavy losses to disease and sparse rangeland. In time, the Texas-bred beef breeds slowly gained acceptance in Australia as imperial identity constructs gave way to economic and environmental determinism. The diffusion of agricultural knowledge in response to global markets is indeed representative of early and persistent globalization.
