Effects of Immaturity on Juveniles’ Miranda Comprehension and Reasoning
Over the last several decades, researchers have documented how impaired reasoning by adult offenders impeded the intelligent waiver of Miranda rights. Logically, it stands to reason that juveniles – who are developmentally less mature and have less life experience than their adult counterparts – would possess even greater impairment, thereby heightening their risk for invalid Miranda waivers. Juvenile Miranda research supports this notion; with some researchers finding that psychosocial maturity, among other factors, affect a juvenile’s understanding of their rights. Yet, relatively few studies have examined its relation to Miranda reasoning and decision-making. Thus, the current study investigated the specific role of maturity in juveniles’ Miranda comprehension and reasoning. Participants included 236 legally-involved juveniles recruited from either a juvenile detention center or a juvenile justice alternative education program. The effects of psychosocial maturity were examined on a variety of Miranda-related measures and assessed a broad range of Miranda abilities. It was found that, in general, immature juveniles performed more poorly on all Miranda measures as compared to their mature counterparts. However, the impact of maturity varied considerably depending on the ability. Specifically, maturity was most important in the context of Miranda reasoning. As a novel addition to the literature, the current study also investigated the effects of developmental timing on maturity (i.e., immaturity-delayed versus immaturity-expected) on Miranda abilities.
Exceedance Frequency Analysis of Urban Stormwater Quality and Its Relation to Land Use Change, Denton, Texas
Urbanization causes various environmental issues including water pollution, air pollution, and solid waste. Urbanization of watersheds has a profound influence on the quality of stormwater runoff. The quality of stormwater runoff is highly associated with land use. This study analyzed the exceedance frequency of stormwater quality in five watersheds of Denton over eleven years and also analyzed the relationship between stormwater quality and land use/cover of each watershed. The results showed that the most of the water quality parameters that were examined in the Lower Pecan watershed exceeded their threshold most frequently. The higher frequency of exceedance in this watershed can be attributed to the wastewater treatment plant and landfill site. Total suspended solids and turbidity were frequently exceeded in Hickory and Clear Creek watersheds. Conductivity was found to have highest percentage of exceedance in Upper Pecan and Cooper watersheds. Thus, rural watersheds were related with higher exceedance of TSS and turbidity whereas urban watersheds were related with higher exceedance of conductivity.
Community Gardening: a Novel Intervention for Bhutanese Refugees Living in the USA
Since 2008, the United States (USA) has resettled thousands of Bhutanese refugees, providing brief financial support and pathways to citizenship. Despite the efforts of governing bodies and voluntary agencies which facilitate resettlement, many refugees struggle with adapting to the vastly different lifestyle, economy, language and social structures. In particular, effectively addressing psychological needs of this population is a challenge for service providers operating within an expensive health care system based on Western constructs of mental health. In response to this challenge, refugee resettlement agencies throughout the country use community gardens to promote psychological healing, self-sufficiency, community engagement, and a return of human dignity. Though success of these programs is being shared in the media, there has yet to be empirical data examining their impact. The current study tested whether Bhutanese refugee engagement in a community garden impacts symptoms of depression, anxiety, PTSD and somatic complaints. The study also investigated whether community gardening is associated with perceptions of social support and adjustment to life in the United States. Quantitative and qualitative data was collected from 50 adult Bhutanese refugees in Fort Worth, Texas. Gardening was significantly related to increased social support overall, a key factor in overall functionality within communal cultures; and specifically perceived tangible support was increased. A significant effect of gardening was also found for adjustment. Although a significant effect was not found for psychological and somatic symptoms, there is still evidence of effects on somatic complaints. Varying results from quantitative and qualitative data warrant further investigation into the nuanced work of clinical research and advocacy with refugee populations.
Operationalizing a Reading Culture at Rio Hondo Junior High
A rural Rio Grande Valley school has continuously performed below the state average on the reading portion of the State Assessment of Academic Readiness. One of the concerns expressed amongst teachers and staff is the student’s lack of desire to read for pleasure or for academic purposes. This study examines the attitudes of students and staff in towards reading by focusing on the school’s reading culture. A mixed methods approach consisting of interviews, participant observation, a focus group, and a survey was employed in this study. The study found that the teachers and students maintained two polarizing perceptions of their reading culture. Based on these findings the following recommendations were made: create a literature-centered curriculum, increase and vary the selection of school library books, and align teachers’ perception with the students’ perception to create a unified reading culture.
Evaluation of the Influence of Non-Conventional Sources of Emissions on Ambient Air Pollutant Concentrations in North Texas
Emissions of air pollutants from non-conventional sources have been on the rise in the North Texas area over the past decade. These include primary pollutants such as volatile organic compound (VOC) and oxides of nitrogen (NOx) which also act as precursors in the formation of ozone. Most of these have been attributed to a significant increase in oil and gas production activities since 2000 within the Barnett Shale region adjacent to the Dallas-Fort Worth metroplex region. In this study, air quality concentrations measured at the Denton Airport and Dallas Hinton monitoring sites operated by the Texas Commission on Environmental Quality (TCEQ) were evaluated. VOC concentration data from canister-based sampling along with continuous measurement of oxides of nitrogen (NOx), ozone (O3), particulate matter (PM2.5), and meteorological conditions at these two sites spanning from 2000 through 2014 were employed in this study. The Dallas site is located within the urban core of one of the fastest growing cities in the United States, while the Denton site is an exurban site with rural characteristics to it. The Denton Airport site was influenced by natural gas pads surrounding it while there are very few natural gas production facilities within close proximity to the Dallas Hinton site. As of 2013, there were 1362 gas pads within a 10 mile radius to the Denton Airport site but there were only 2 within a 10 mile radius to Dallas Hinton site. The Dallas site displayed higher concentrations of NOx and much lower concentrations of VOC than the Denton site. Extremely high levels of VOC measured at the Denton site corresponded with the increase in oil and gas production activities in close proximity to the monitoring site. Ethane and propane are two major contributors to the measured VOC concentration, suggesting the influence of fugitive emissions of natural gas. ...
Health-related Quality of Life and Social Engagement in Assisted Living Facilities
This research project aims to clarify the factors that impact successful aging in Assisted Living facilities (ALFs) in Denton County, Texas. We hypothesize that social disengagement decreases physical and mental components of quality of life. This exploratory research project employed standardized questionnaires to assess residents in the following domains; HRQOL, social engagement status, level of cognition, depression, and the level of functioning. This study collected data from 75 participants living in five ALFs. The average of Physical Component Scale (PCS) and Mental Component Scale (MCS) was 35.33, and 53.62 respectively. None of the participants had five or more social contacts out of facilities, and two-third of them had two or less social contacts. On average, those participants who were more socially engaged had higher score of MCS compared with disengaged counterparts. The level of physical function significantly affects social engagement, when people with more disabilities are more likely to be socially disengaged. Social engagement and depression significantly impact MCS, when depression is a mediating factor between social engagement and mental component of quality of life. Considering the expansion in aging population in the United States within the next three decades, the demand for high quality long-term care will skyrocket consequently. This study reveals that external social engagement can sustain HRQOL of residents in assisted living facilities.
A Tale of Two Cities: Exploring the Dual Language Program Implementation and Biliteracy Trajectories at Two Schools
With the increase in emergent bilinguals and higher standards for all, the challenge for educational stakeholders is to fully utilize dual language programs as a prominent means toward meeting and surpassing rigorous state and national standards. Part of maximizing dual language programs’ impact, and the purpose of this study, was to provide detailed analyses of program models and student biliteracy development. Thus, the research questions sought to explore the level of understanding and implementation of dual language programs in general and the biliteracy component in particular at each campus, before documenting the second through fifth grade English and Spanish reading biliteracy trajectories of students at each school. Both campuses experienced more challenges in the implementation of the program structure, staff quality, and professional development rather than in curriculum and instruction. Furthermore, although both campuses’ students experienced positive trajectories towards biliteracy by the end of fifth grade, each campus was characterized by different rates and correlation between English and Spanish reading growth in each grade. Finally, the researcher conducted a split plot MANOVA to examine how much variance in the biliteracy trajectories was explained by school attendance, gender, initial English oral language and initial Spanish oral language; only school of attendance and initial English oral language levels explained the variance in biliteracy trajectories for students at these campuses.
Everyday Performances in U.S. Household Kitchens
BMA Innovation Consulting is committed to serving consumers products that can play a more meaningful role in household cleaning. So far, their innovation department has used psychology-based principles and approaches that have helped them understand consumers’ preferences, attitudes and claimed needs in household cleaning. That said, little information has been collected on the active role that products play or could play as participants in the everyday dynamics of US consumers. An anthropological approach to the study of U.S. kitchens, as an important center of family interaction in U.S. households, should yield important insights to the design and development of products that can more effectively and more actively participate in those dynamics. With this project I am fundamentally proposing a new approach to the identification of critical product design requirements. Figure on the right shows the key differences between the psychology-derived principles the organization is mostly using today vs. the anthropological lenses through which I will be conducting my research. Overall, I will be leveraging existing knowledge in the “individual desires” realm, connecting it to the collective situation & cultural context within which “cleaning action” emerges.
The Use of Faunal Remains for Identifying Shifts in Pit Structure Function in the Mesa Verde Region: a Case Study From Goodman Point
The archaeofaunal remains left by the Ancestral Puebloan people of Goodman Point Unit provides a valuable, yet underutilized resource into pit structure function. This thesis explores temporal changes in pit structure use and evaluates if a final feast occurred during a kiva decommissioning. The results from zooarchaeological analyses of a pithouse and two great kivas suggest that changes in pit structures at Goodman Point mimic the regional trend toward specialization until late Pueblo III. Cross-cultural studies on feasts, southwest ethnographies and previous zooarchaeological work established methods for identifying a feast. The analysis of differences in faunal remains from a great kiva and multiple room block middens imply that the remains in the kiva were from a final feast prior to a decommissioning ceremony and were not fill. Spatially and temporally the great kiva appears to be a unique, specialized structure in the cultural development of the Goodman Point community.
Back on the Home Front: Demand/Withdraw Communication and Relationship Adjustment Among Student Veterans
Today’s military encompasses a wide variety of families who are affected by deployments in multiple and complex ways. Following deployments, families must reconnect in their relationships and reestablish their way of life. Appropriate and effective communication during this time is critical, yet many military couples struggle with this process. Moreover, student service members/veterans and their families are in a unique position. In addition to coping with changes in their marital relationship, student veterans may feel isolated or unsupported on college campuses, often experiencing anxiety, depression, posttraumatic stress, or suicidality. The current study seeks to bridge the gap between the military family literature and the student service member/veteran literature by examining how deployment experiences, mental health issues, and communication patterns influence post-deployment relationship adjustment among student veterans. Analyses tested whether communication style and/or current mental health concerns mediate associations between combat experiences and couples’ relationship adjustment, as well as between experiences in the aftermath of battle and relationship adjustment. Results suggest that although posttraumatic stress is significantly related to deployment experiences among student veterans, participants report no significant negative effects of deployment on relationship adjustment. Communication style, however, was significantly associated with relationship adjustment, and a lack of positive communication was found to correlate with PTSD diagnosis. Research and clinical implications are discussed.
Does an Online Post-baccalaureate Secondary Teacher Certification Program Produce Certified Teachers Who Remain in the Field?
Given issues in education concerning teacher shortages, the omnipresence of alternative certification programs and the growth of online programs in higher education, this study investigated teacher retention for 77 secondary education teachers who completed an online teacher preparation program in Texas. Teacher retention was examined from 2003-2013 and investigated the influence of factors such personal characteristics, working conditions and school setting characteristics on teacher retention. Data was collected electronically utilizing a survey instrument designed by two teacher education experts and I. A total of 21 variables and two open-ended questions were investigated using the survey instrument. Exploratory factor and hierarchical multiple regression analyses were conducted to identify a multi-factor model for teacher retention utilizing the participants' survey responses. These analyses yielded evidence of the program's effectiveness in preparing teachers for long careers. Specifically, the areas of program support, field experience, and classroom management were statistically significant factors that contributed positively to teacher retention. Additionally, variables outside the program, were examined. These factors included personal characteristics, working conditions, and school setting factors. The predictor model accounted for 56% of the variance; F (17, 54) = 3.015; p = < 0.001. In particular, working conditions contributed to 41% of the variance associated with the teacher retention model. A qualitative analysis of open-ended survey questions was used to further examine decisions to remain in teaching. Support of administration, colleagues, staff, and parents was shown to influence teacher retention.
A Critical Medical Anthropology Approach to Advocating for Social Justice and Policy Change in Pesticide Use and Practice to Reduce Health Risks Among Hispanic/Latinos in Central California
This mixed methods research was conducted in the fall of 2014 to understand the perceptions and experiences of health risks and health outcomes due to pesticide exposure among community members (n=13) - concerned community members, agriculture workers and teachers- that live in the Central California agriculture counties of Monterey, Santa Cruz, Tulare, Fresno and Madera. This research explored: 1) The crops growing in participants’ communities, and how exposure to pesticides used in these crops pose potential health risks to participants and their communities 2) How pesticide exposure is impacting Hispanic/Latino communities in Central California, particularly those that are most vulnerable including school children, agriculture workers, and community members 3) The major public health concerns of impacted communities 4) Feelings of empowered to advocate for community health and environment and 5) What impacted communities wish to see on behalf of government and agribusiness to protect public health from pesticide exposure and toxins.
Efficiency of Nitrate and Phosphorus Removal in a Working Rain Garden
Rain gardens are low impact developments designed to mitigate a suite of issues associated with urban stormwater runoff. The site for this study was a Denton City rain garden at the Denton Waste Water Treatment Plant. Nitrogen and phosphorus removal was examined in light of two overflow events comprised of partially treated wastewater from an upslope anaerobic digester pond. Nitrate removal efficiency was examined across differing dry spell intervals of 5, 8, and 12 d, displaying a moderate negative correlation (r2 = 0.59). Continued phosphorus removal capacity was assessed, showing phosphorus removal in cases where P was in excess of 0.8 mg/L, reflecting an equilibrium phosphorus concentration. A high expanded shale component in the soil media (25%) was likely a factor in the continued removal of phosphorus. Overall the rain garden proved to be a large source of nitrate (+425%) and total nitrogen (+61%) by mass. The study showed that while the rain garden intercepted a large volume of partially treated wastewater during the overflow events, preventing it from reaching a nearby creek, the mitigation of an acute event has extended to a chronic one as nitrogen is gradually processed and flushed from the system as nitrate.
Other Identities As Assumed: Job Descriptions Among Classified Employees in a Public School System
The aim of this thesis is to investigate the current status of job descriptions at a Public School System, in [City], [State], USA, and to make recommendations for improvement in terms of job description content, format, and the creation and updated processes. This work covers job descriptions among classified employees and does not cover job descriptions for instructional staff (teachers, principals, etc.) or Executive Administrative Staff. The work begins by introducing the reader to the client and the current status of the client's job descriptions. The demographics of the subject population are discussed as well as the research methodologies. Findings are presented in light of research data and analyzed using Social Identity Theory, as well as business leadership principals. Finally deliverables are provided and recommendations are made. The thesis argues that application of Social Identity Theory and business leadership principals will support the ongoing job description processes by engaging employees in the process with supervisors leading the process
Women and the Superintendency: a Study of Texas Women Superintendents
Education remains one of the most gender imbalanced fields, with disproportionately fewer women in higher levels of leadership. Women who reach leadership positions in education experience many triumphs and tribulations during their tenures as principals, assistant superintendents, and superintendents. The experiences of these women in their various administrative levels of leadership can provide important insight into the reasons for their success as women superintendents in Texas. This research has probed the career trajectory of nine women who have successfully attained and retained superintendencies in Texas to determine what career decisions have helped them and the challenges these women have faced in their positions. A qualitative research method, open-ended interviews, yielded several findings of what women considered important in proceeding from teaching through the various levels and ending in becoming superintendents. According to nine successful women superintendents in Texas, there are specific characteristics one can bring to the table that would really make a difference: Communication, collaboration, compassion, preparedness, hard work, and passion. All nine participants overcame challenges when climbing to the higher levels of leadership in education. These women have achieved success in the superintendency, and several factors appear to have played into the success of these women who have achieved in education’s top position.
The Longitudinal Impact of Technology Immersion Through a One-to-One Mobile Technology Program on Reading and Math Performance in a Rural Title I Public School District
In conjunction with the Texas Technology Immersion Pilot program (TIP), the State of Texas implemented a four-year annual evaluation called the Evaluation of the Texas Technology Immersion Pilot (eTxTiP). It focused on the technology immersion experience through one-to-one mobile technology of sixth grade students in 22 selected middle schools. Initial findings suggested academic growth, especially in math, increased rigor of student work, greater teacher collaboration, a more positive school environment, and transformation of instructional practices. This study focused on one of the original schools selected to participate in the TIP program, exploring the impact over time of one-to-one mobile technology on one group of students over an 8-year period beginning with their third grade year. The selected school’s demographic makeup reflected a large number of schools within the state, including its size, rural location and economically disadvantaged student population. Based on an interrupted time series design, state assessment data was analyzed using a piecewise growth model. The study revealed no statistically significant academic growth in reading and math performance among the participants.
Computational Methods for Vulnerability Analysis and Resource Allocation in Public Health Emergencies
POD (Point of Dispensing)-based emergency response plans involving mass prophylaxis may seem feasible when considering the choice of dispensing points within a region, overall population density, and estimated traffic demands. However, the plan may fail to serve particular vulnerable sub-populations, resulting in access disparities during emergency response. Federal authorities emphasize on the need to identify sub-populations that cannot avail regular services during an emergency due to their special needs to ensure effective response. Vulnerable individuals require the targeted allocation of appropriate resources to serve their special needs. Devising schemes to address the needs of vulnerable sub-populations is essential for the effectiveness of response plans. This research focuses on data-driven computational methods to quantify and address vulnerabilities in response plans that require the allocation of targeted resources. Data-driven methods to identify and quantify vulnerabilities in response plans are developed as part of this research. Addressing vulnerabilities requires the targeted allocation of appropriate resources to PODs. The problem of resource allocation to PODs during public health emergencies is introduced and the variants of the resource allocation problem such as the spatial allocation, spatio-temporal allocation and optimal resource subset variants are formulated. Generating optimal resource allocation and scheduling solutions can be computationally hard problems. The application of metaheuristic techniques to find near-optimal solutions to the resource allocation problem in response plans is investigated. A vulnerability analysis and resource allocation framework that facilitates the demographic analysis of population data in the context of response plans, and the optimal allocation of resources with respect to the analysis are described.
Healthcare Utilization and Health Outcomes: US-born and Foreign-born Elderly Asian Americans
In order to better understand variations of health behaviors between US-born and foreign-born elderly Asian Americans (65+) in the United States, the research aims to explore relationships among health outcomes, healthcare utilization, and sociodemographic characteristics. Data from the National Health Interview Survey 1998-2012 is used to construct structural equation models for the US born group and for the foreign born group. The results found that there is a reciprocal relationship between health outcomes and healthcare utilization in both groups. Use of healthcare services can positively affect health outcomes, while better health outcomes reduce the need for healthcare utilization. In addition, some sociodemographic characteristics, such as age, sex, and marital status have a direct effect on health outcomes, but some others, such as education, family size and combined family income, have an indirect effect on health outcomes via healthcare utilization. The region of residency has both direct and indirect effects on health outcomes. Regarding the effects of predictors on health outcomes, US-born elderly Asians usually receive more health advantages from using institutional health services than foreign-born elderly Asians. Practitioners, social gerontologists, and policy makers should be cautious about assuming that there is a positive impact of increased healthcare utilization on health outcomes in elderly Asian Americans.
Establishing a History and Trajectory of LGBT and Queer Studies Programs in the American Research University: Context for Advancing Academic Diversity and Social Transformation
The system of higher education in the United States of America has retained some of its original character yet it has also grown in many ways. Among the contemporary priorities of colleges and universities are undergraduate student learning outcomes and success along with a growing focus on diversity. As a result, there has been a growing focus on ways to achieve compositional diversity and a greater sense of inclusion with meaningful advances through better access and resources for individuals from non-dominant populations. The clearest result of these advances for sexual and gender diversity has been a normalization of lesbian, gay, bisexual, transgender, and queer (LGBTQ) identities through positive visibility and greater acceptance on campus. However, it appears that relatively few institutions have focused on improving academic diversity and students’ cognitive growth around LGBTQ issues. Through historical inquiry and a qualitative approach, this study explored the fundamental aspects of formal LGBTQ studies academic programs at some of the leading American research universities, including Cornell University, the University of Maryland, College Park, and the University of Texas at Austin – a purposeful sample chosen from the Association of American Universities (AAU) member institutions with organized curricula focused on the study of sexual and gender diversity. The analysis of primary and secondary sources, including documents and interviews, helped create historical narratives that revealed: a cultural shift was necessary to launch a formal academic program in LGBTQ studies; this formalization of LGBTQ studies programs has been part of the larger effort to improve the campus climate for sexual and gender diversity; and there has been a common pattern to the administration and operation of LGBTQ studies. Clearly, the research shows that LGBTQ studies, as a field of study and formal curriculum, has become institutionalized at the American research university. A key outcome of this ...
Why the Fuse Blew: the Reasons for Colonial America’s Transformation From Proto-nationalists to Revolutionary Patriots: 1772-1775
The most well-known events and occurrences that caused the American Revolution are well-documented. No scholar debates the importance of matters such as the colonists’ frustration with taxation without representation, the Boston Massacre, the Boston Tea Party, and the Coercive Acts. However, very few scholars have paid attention to how the 1772 English court case that freed James Somerset from slavery impacted American Independence. This case occurred during a two-year stall in the conflict between the English government and her colonies that began in 1763. Between 1763 and 1770, there was ongoing conflict between the two parties, but the conflict temporarily subsided in 1770. Two years later, in 1772, the Somerset decision reignited tension and frustration between the mother country and her colonies. This paper does not claim that the Somerset decision was the cause of colonial separation from England. Instead it argues that the Somerset decision played a significant yet rarely discussed role in the colonists’ willingness to begin meeting with one another to discuss their common problem of shared grievance with British governance. It prompted the colonists to begin relating to one another and to the British in a way that they never had previously. This case’s impact on intercolonial relations and relations between the colonies and her mother country are discussed within this work.
Community-based Participatory Research: HIV in African American Men Who Have Sex with Men
To date, traditional behavioral interventions have done little to reduce the prevalence and transmission of HIV among African American men who have sex with men (AAMSM), a highly at risk group. Some researchers theorize that the lack of success may be because these interventions do not address contextual factors among AAMSM. Community-based participatory research (CBPR) is one approach to research with the potential to lead to effective interventions in the future. CBPR is a collaborative, mixed-methods and multidisciplinary, approach to scientific inquiry, which is conducted with, and within, the community. The current study follows the CBPR approach to engage and develop a relationship with the African American communities in the Dallas/Fort Worth Metroplex. Contextual issues were discussed in order to identify emerging themes regarding HIV health related issues among AAMSM to provide the groundwork for continued CBPR research and future interventions with AAMSM in the Dallas/Fort Worth Metroplex. To accomplish this goal, researchers began the CBPR process by conducting interviews and focus groups with a sample of approximately 62 (34 from key informant interviews, 28 from focus groups [gender balanced]) AIDS service organization leaders and workers, advocates, medical doctors and community members with first-hand knowledge of HIV health issues in the AAMSM community. Transcripts of these interviews and focus groups were analyzed to identify emerging themes at the societal (religious doctrine, African American Culture, age-related norms and stigma), community (education, religious views/policy and community norms) and individual (disclosure, personal identity, sexual behavior/risk, accessing care and communication) levels. This data was used to create a holistic narrative report that will be used to direct the community advisory board (CAB) and guide future research and interventions.
Exploring the Dual-natured Impact of Digital Technology on Student-classroom Engagement in a Texas Public High School
The past decade has become rife with an eagerness to integrate new digital technology into teaching. While there have been decades of research done on the importance of curriculum and pedagogy on student engagement, findings of actual technology integration are scarce. Moreover, what does it take to engage students in classroom activities and lessons when technology is introduced? The purpose of this study was to explore how digital technology, when integrated into classroom teaching and activities, impacted the students-classroom engagement based on the interim-cognitive, meta-cognitive, motivational, and behavioral markers. This was explored in a Texas public high school across the four core classes (English, Math, Science, and Social Studies. Data was collected in the form of observational field notes, transcripts of recorded lessons, and Likert-scaled surveys. Thematic analysis was used in analyzing qualitative data, Pearson’s correlation of those components found by factor analysis verified three of the five themes identified from the thematic analysis with statistical significance. The findings suggest that mere use of technology does not have a profound impact on student engagement. Instead, technology tends to amplify the existing classroom culture and social norms agreed upon between the teacher and their students. Texas teachers and students are also redefining the meaning of curriculum to include technology as a result of the attempted integration. This research finds that students’ hands-on activities under teachers’ guidance with the use of technology excel when teachers are molding digital work.
No Quarter: the Story of the New Orleans Greys
The purpose of this thesis document is to explain the process of making the documentary film, No Quarter: The Story of the New Orleans Greys. The document is organized by having the prospectus and the film proposal at the beginning, with the body describing how the film was made based on the prospectus. The purpose of the film is to tell the history of a unit of volunteers in the Texas Revolution, the New Orleans Greys. The document describes the methods used to make the film and how it will be distributed to the intended audience. As the thesis explains, the film changed slightly from the prospectus, however the resulting film was successful in telling the history of the little-known New Orleans Greys.
Taking It to the Streets: the History of Gay Pride Parades in Dallas, Texas: 1972-1986
This thesis describes the organization of two waves of pride parades in the city of Dallas, Texas. Using more than 40 sources, this work details how LGBT organizers have used pride parades to create a more established place for the LGBT community in greater Dallas culture. This works adds to the study of LGBT history by focusing on an understudied region, the South; as well as focusing on an important symbolic event in LGBT communities, pride parades.
An Initial Validation of the Virtual Reality Stroop Task (VRST) in a Sample of OEF/OIF Veterans
Currently, neuropsychologists rely on assessment instruments rooted in century old theory and technology to make evaluations of military personnel’s readiness to return-to-duty or return to their community. The present study sought to explore an alternative by evaluating the validity of a neuropsychological assessment presented within a virtual reality platform. The integration of a neuropsychological assessment into a cognitively and emotionally demanding virtual environment – reminiscent of a combat experience in Iraq – offers a more ecologically valid manner in which to evaluate the cognitive skills required in theater. U.S. military veterans’ (N = 50) performance on the Virtual Reality Stroop Task (VRST) was compared with performance on a paper-and-pencil, a computer adapted version of the Stroop task, and the subtests included in the Automated Neuropsychological Assessment Metrics-4 (ANAM4) TBI-MIL test battery. Results supported the validity of the VRST, indicating it demonstrates the typical Stroop effect pattern. The emotional salience of the VRST resulted in slowed reaction time compared to the ANAM Stroop. Further, the complex interference condition of the VRST offers opportunities for evaluation of exogenous and endogenous attentional processing. In the evaluation of threat, participants were noted to perform more accurately and more quickly in low threat versus high threat zones. Ancillary inquiries found no clinically meaningful findings regarding the role of deployment or post-concussive symptoms, and mixed findings regarding the effect of posttraumatic stress symptoms on neuropsychological performance among the three tested modalities.
The Needs and Resources of International Torture Survivors Living in the Dallas Fort Worth (DFW) Metroplex: an Investigation of Healing and Assimilation Perceived by Center for Survivors of Torture’s Clients and Staff As Well As the Greater Resettlement Community
Torture survivors find difficulty navigating through an unfamiliar healthcare and social service system. Many survivors who already face Post Traumatic Stress Disorder (PTSD), anxiety, and depression also endure a secondary threat which leads to re-traumatization through the struggles of acculturation. The aim of this study is to determine: 1. Identify differences and assumptions between service providers’ and clients’ definitions of self-sufficiency; 2. Examine prominent barriers to self-sufficiency that survivors encounter; 3. Pinpoint the survival strategies that survivors use in order to cope with life in DFW; 4. Determine what resources CST staff, area service providers, and survivors feel need to be improved for CST and the DFW metroplex.
The Happy Kitchen: Community Designed Cooking Classes
Equitable access to healthy food is a multifaceted issue faced by many underserved populations. Intimate understanding of individual communities’ food practices allows for the creation of community-based interventions that elaborate upon specific needs and desires. Through collaborative research and action, this study aims to become better informed of the current eating habits of community members participating in The Happy Kitchen program at Wesley Rankin Community Center in West Dallas, how those habits have changed over time, and the factors that contribute to access and utilization of a healthy diet. This research seeks to develop a dialectical relationship between the participants and GROW North Texas to design relevant cooking classes and interventions in West Dallas; thereby increasing access to and consumption of nutritious food.
Photo-induced Toxicity of Deepwater Horizon Spill Oil to Four Native Gulf of Mexico Species
The 2010 Deepwater Horizon oil spill resulted in the accidental release of millions of barrels of crude oil into the Gulf of Mexico (GoM). Photo-induced toxicity following co-exposure to ultraviolet (UV) radiation is one mechanism by which polycyclic aromatic hydrocarbons (PAHs) from oil spills may exert toxicity. Blue crab (Callinectes sapidus) are an important commercial and ecological resource in the Gulf of Mexico and their largely transparent larvae may make them sensitive to PAH photo-induced toxicity. Mahi-mahi (Coryphaena hippurus), an important fishery resource, have positively buoyant, transparent eggs. These characteristics may result in mahi-mahi embryos being at particular risk from photo-induced toxicity. Red drum (Sciaenops ocellatus) and speckled seatrout (Cynoscion nebulosus) are both important fishery resources in the GoM. They spawn near-shore and produce positively buoyant embryos that hatch into larvae in about 24 h. The goal of this body of work was to determine whether exposure to UV as natural sunlight enhances the toxicity of crude oil to early lifestage GoM species. Larval and embryonic organisms were exposed to several dilutions of water accommodated fractions (WAF) from several different oils collected in the field under chain of custody during the 2010 spill and two to three gradations of natural sunlight in a factorial design. Here, we report that co-exposure to natural sunlight and oil significantly reduced larval survival and embryo hatch compared to exposure to oil alone.
Influence of the Choice of Disease Mapping Method on Population Characteristics in Areas of High Disease Burdens
Disease maps are powerful tools for depicting spatial variations in disease risk and its underlying drivers. However, producing effective disease maps requires careful consideration of the statistical and spatial properties of the disease data. In fact, the choice of mapping method influences the resulting spatial pattern of the disease, as well as the understanding of its underlying population characteristics. New developments in mapping methods and software in addition to continuing improvements in data quality and quantity are requiring map-makers to make a multitude of decisions before a map of disease burdens can be created. The impact of such decisions on a map, including the choice of appropriate mapping method, not been addressed adequately in the literature. This research demonstrates how choice of mapping method and associated parameters influence the spatial pattern of disease. We use four different disease-mapping methods – unsmoothed choropleth maps, smoothed choropleth maps produced using the headbanging method, smoothed kernel density maps, and smoothed choropleth maps produced using spatial empirical Bayes methods and 5-years of zip code level HIV incidence (2007- 2011) data from Dallas and Tarrant Counties, Texas. For each map, the leading population characteristics and their relative importance with regards to HIV incidence is identified using a regression analysis of a CDC recommended list of socioeconomic determinants of HIV. Our results show that the choice of mapping method leads to different conclusions regarding the associations between HIV disease burden and the underlying demographic and socioeconomic characteristics. Thus, the choice of mapping method influences the patterns of disease we see or fail to see. Accurate depiction of areas of high disease burden is important for developing and targeting appropriate public health interventions.

Texas Pararnormalists mixes participatory and observational styles in an effort to portray a small community of paranormal practitioners who live and work in and around North Texas. These practitioners include psychics, ghost investigators, and other enthusiasts and seekers of the spirit world. Through the documentation of their combined perspectives, Texas Paranormalists renders a portrait of a community of outsiders with a shared belief system and an unshakeable passion for reaching out into the unknown.
Prison Notes: an Introductory Study of Inmate Marginalia
This thesis introduces the study of inmate marginalia as a method for understanding inmates’ uses of texts in prison libraries and for understanding the motivations for these uses. Marginalia are the notes, drawings, underlining, and other markings left by readers in the texts with which they interact. I use the examples of the Talmudic projects to set a precedent for the integration of marginal discourses into the central discourse of society. Next, I discuss the arguments surrounding the use of texts in prison libraries, including an outline for an ideal study of inmate marginalia. Finally, I discuss the findings of my on-site research at four prison libraries in Washington State. After scanning evidence of marginalia from forty-eight texts, a relatively small sample, I divided the marginalia by gender of facility, genre of text, address of the marginalia, and type of marginalia and found statistically significant correlations (p < 0.05) between gender and genre, gender and address, gender and type, and genre and type. However, while these correlations are statistically weak and require further investigation, the statistically significant correlations indicate the potential for integrating inmate marginalia studies into the scholarly discussions regarding inmates’ interactions with texts in prison.
Creating Community in Isolation: the History of Corpus Christi’s Molina Addition, 1954-1970
“Creating Community in Isolation: The History of Corpus Christi’s Molina Addition, 1954-1970” examines the history of the Molina Addition in Corpus Christi, Nueces County, Texas, and its serving district, the West Oso Independent School District, from 1954 to 1970. Specifically, this essay begins with an analysis of the elite-driven campaign to annex the blighted Molina Addition in September and October 1954. The city intended to raze the neighborhood and develop middle-class homes in place of the newly annexed neighborhood. Following the annexation of the Molina Addition, African American and ethnic Mexican residents initiated protracted struggles to desegregate and integrate schools that served their area, the West Oso Independent School District, as detailed in the chapter, “The West Oso School Board Revolution.” The chapter examines the electoral “revolution” in which Anglo rural elites were unseated from their positions on the school board and replaced by African American and ethnic Mexican Molina Addition residents. The third chapter, “Building Mo-Town, Texas,” focuses on residents’ struggle to install indoor plumbing, eliminate pit privies, construct paved roads, and introduce War on Poverty grants to rehabilitate the neighborhood. This chapter also offers a glimpse into the social life of Molina youth during the 1960s.
Migration Information Gathering by Mexican-origin Immigrants in the Pre-migration Phase
U.S. immigration procedures are complex and may elude the average individual seeking admission to the United States. Understanding this, the current study investigates how information resources are used by potential migrants to learn about the migratory process. Using a mixed-methods approach, I interviewed 30 Mexican immigrants with unauthorized immigration experience about the process of gathering migration information in the pre-migration phase. Qualitative data were coded using seven themes generated from the primary research questions, including: Information Resources, Resources Used During Migration, Motivation for Migration, Method of Migration, Lack of Information/Misinformation, Types of Help and Types of Information. Findings suggest that the factors motivating migrants to come to the U.S. are combined in complex ways and lack of information about legal alternatives to unauthorized migration is an important factor influencing method of migration. Also, while access to new information resources is increasing, these resources are not being tapped for migration information.
The Influence of Local Forage Variability on White-tailed Deer (Odocoileus virginianus) Body Size at Fort Hood, Texas
Nutritional quality and availability is thought to regulate geographic patterns of variability in animal body size due to phenotypic plasticity. The purpose of this study is to determine how vegetation quality, abundance and population density influence white-tailed deer (Odocoileus virginianus) body size on a subregional spatial scale at Fort Hood, Texas. Harvest and census records are used to test the hypothesis that white-tailed deer exhibit phenotypic plasticity (e.g. larger body size) in response to differences in vegetation quality and availability. Results from these analyses suggest that forage quality and abundance alone is not a main driver of white-tailed deer body size. Analysis of deer population density (generally) resulted in an inverse relationship with body size. Areas with high quality forage and low population density support larger deer while areas with low quality forage and high density support smaller than average deer. The few exceptions occur in areas exhibiting poor quality forage and low population density or high forage quality and high density. Results from this study suggest that continued overcrowding of deer within isolated areas may eventually lead to efficiency phenotypic conditions producing smaller sized deer. These results could prove useful in interpreting deer population responses to harvest management. For successful local management of deer, studies examining the combined influence of habitat variables (such as forage quality, abundance and population density) on deer health offer managers valuable information needed to establish annual harvest goals and understand deer-habitat relationships relative to carrying capacity.

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 unable to do so due to arguments, selfishness, corruption, failures, and inaction on the part of both sides. However, this thesis will ultimately reveal it was lack of full support from Texas legislators, deriving from the idea that this system was not one of their top priorities among the state’s concerns, that led to the inability of the Texas mental health care system to properly assist their patients.
Retention: Course Completion Rates in Online Distance Learning
Online courses in higher education have a reputation for having a lower course completion or retention rate than face-to-face courses. Much of this reputation is based upon anecdotal evidence, is outdated, or is on a small scale, such as a comparison of individual courses or programs of instruction. A causal-comparative analysis was conducted among 11 large, high research public universities. The universities were compared to each other to determine if differences existed between online and face-to-face course completion; undergraduate and graduation online course completion was analyzed for differences as well. The findings suggested the magnitude of the differences between online and face-to-face completions rates was small or negligible. The area which showed a higher magnitude of difference was in the comparison between undergraduate and graduate online course completion; the practical significance could be worth considering for educational purposes.
The Forty-fifth Illinois Volunteer Infantry Regiment: the Washburne Lead Mine Regiment in the Civil War
Of the roughly 3,500 volunteer regiments and batteries organized by the Union army during the American Civil War, only a small fraction has been studied in any scholarly depth. Among those not yet examined by historians was one that typified the western armies commanded by the two greatest Federal generals, Ulysses S. Grant and William T. Sherman. The Forty-fifth Illinois Volunteer Infantry was at Fort Donelson and Shiloh with Grant in 1862, with Grant and Sherman during the long Vicksburg campaign of 1862 and 1863, and with Sherman in the Meridian, Atlanta, Savannah, and Carolinas campaigns in the second half of the war. These Illinois men fought in several of the most important engagements in the western theater of the war and, in the spring of 1865, were present when the last important Confederate army in the east surrendered. The Forty-fifth was also well connected in western politics. Its unofficial name was the “Washburne Lead Mine Regiment,” in honor of U.S Representative Elihu B. Washburne, who used his contacts and influences to arm the regiment with the best weapons and equipment available early in the war. (The Lead Mine designation referred to the mining industry in northern Illinois.) In addition, several officers and enlisted men were personal friends and acquaintances of Ulysses Grant of Galena, Illinois, who honored the regiment for their bravery in the final attempt to break through the Confederate defenses at Vicksburg. The study of the Forty-fifth Illinois is important to the overall study of the Civil War because of the campaigns and battles the unit participated and fought in. The regiment was also one of the many Union regiments at the forefront of the Union leadership’s changing policy toward the Confederate populace and war making industry. In this role the regiment witnessed the impact of President ...
School and Community Partnerships: Effect on At-risk Elementary Student Populations
The purpose of this study was to investigate the current practices of school and community partnerships in five North Texas elementary schools. In addition, the study focused on the influence community partnerships have on at-risk students based on at-risk indicators data. The literature revealed that when schools, parents, and families work together, students tend to earn higher grades, attend school more regularly, stay in school longer, and enrolled in coursework beyond high school. The target population included approximately 350 administrators, teachers, and paraprofessionals from five North Texas elementary schools. Also included were the respective partners from each of the five elementary schools. This research included online survey instrument and data were gathered and analyzed through a combination of statistical procedures and descriptive and inferential statistics. The results may provide other schools with a profile of school and community partnerships that can be implemented as a method to help their at-risk student populations. Findings included a descriptive analysis of factors that contributed to the success of community engagement efforts as well as those factors that limited those efforts. A secondary purpose of this study was of continuous improvement in developing these approaches through a goal-setting approach. Schools included in the study provided a next steps plan by describing their major goal(s) for improving existing school and community partnerships over the next 3 years.
Impact of Green Design and Technology on Building Environment
Currently, the public has a strong sense of the need for environment protection and the use of sustainable, or “green,” design in buildings and other civil structures. Since green design elements and technologies are different from traditional design, they probably have impacts on the building environment, such as vibration, lighting, noise, temperature, relative humidity, and overall comfort. Determining these impacts of green design on building environments is the primary objective of this study. The Zero Energy Research (ZOE) laboratory, located at the University of North Texas Discovery Park, is analyzed as a case study. Because the ZOE lab is a building that combines various green design elements and energy efficient technologies, such as solar panels, a geothermal heating system, and wind turbines, it provides an ideal case to study. Through field measurements and a questionnaire survey of regular occupants of the ZOE lab, this thesis analyzed and reported: 1) whether green design elements changed the building’s ability to meet common building environmental standards, 2) whether green design elements assisted in Leadership in Energy and Environmental Design (LEED) scoring, and 3) whether green design elements decreased the subjective comfort level of the occupants.
Efficacy in Texas Charter Schools Compared to Traditional Public Schools
The need to spur innovation and improve student performance initiated the formation of, under different legislative acts, charter schools that include variations of traditional public schools. With the enthusiasm and level of investment going into the formation of charter schools, it is necessary to explore whether these schools have achieved their objectives. This study explored whether Texas open enrollment charter schools perform bettered compared to Texas public schools. The study applied a causal comparative quantitative research design. School data on graduation and dropout rates, college preparation, attendance rates, and overall performance were analyzed quantitatively. Student achievement data available for statistical analysis includes student performance on the Texas Assessment of Knowledge and Skills (TAKS) state assessment from 2007 to 2011. Data analysis for race, special programs, at risk, economically disadvantaged, and limited English proficiency was incorporated. Descriptive statistics and analysis of variance techniques were included in the data analysis. The analysis extended to post hoc tests to determine variables that caused variation. The study found Texas open-enrollment charter schools had more African American students but fewer Whites compared to public schools. Students in public schools performed better than those in charter schools, and Whites yielded the best performance. Charter schools had high dropout rates, low attendance, and low graduation rates, while public schools had low dropout rates, high attendance, and high graduation rates. Finally, public schools had more students ready for college than charter schools.
Student and Family Perspectives on Gifted and Advanced Academics Participation for African American High School Students
Many students and their families do not understand the impact of students’ involvement in gifted or advanced academics educational programs and their potentially positive effects and challenges. Nationally African American students are underrepresented in gifted and advanced academics courses in high schools; however, African American students and families often do not advocate for their inclusion in these educational pathways. A survey of literature supporting this study of voices of African American families concerning gifted and advanced academics participation focused on (1) the historical underpinnings for equity and excellence for African American and for gifted and advanced academics learners, (2) how the lack of an agreed upon definition of gifted and advanced academics by the professional field might contribute to the problem, and (3) how African American parents made educational decisions for and with their children, especially concerning college. Employing semi-structured interviews and a focus group, this qualitative case study examined how four students from each of three groups, gifted and talented, advanced academics, and neither, and a representative group of their parents perceived these programs and their children’s involvement in them within the framework provided by a single school district. African American families in this study asked for a partnership to support their children in building resiliency to choose and remain in gifted and advanced academics programs. Students reported that they could access more rigorous coursework if they were supported by mentoring peers, in addition to informed family and educators. The matching intonations and word choices of the children and parents suggested academic success pathways as students carried the voices of their families with them.
Expanding the Notion of Campus Climate: the Effect of Religion and Spirituality on the Perception of Campus Climate
Religion/spirituality is a salient facet of identity for many college students, yet addressing issues related to spirituality/religion is contentious in many higher education institutions. Prior research has shown that various other facets of identity, including race/ethnicity, gender, and sexual orientation, affect a student’s perception of campus climate, but religious/spiritual identity has not been examined in the same manner. Using confirmatory factor analysis and structural equation modeling, this study empirically tests the addition of religion/spirituality to the campus climate theory developed by Hurtado et al. (1999). Data came from the 2010 College Senior Survey administered by the Higher Education Research Institute at the University of California, Los Angeles. Results indicate that religious and spiritual identity have significant direct effects on the perception and other aspects of campus climate. Future research is needed to extend the understanding between religious and spiritual identity and the perception of campus climate.
Testing the Psychometric Properties of the Online Student Connectedness Survey
The Online Student Connectedness Survey (OSCS) was introduced to the academic community in 2012 as an instrument designed to measure feelings of connectedness between students participating in online degree and certification programs. The purpose of this study was to examine data from the instrument for initial evidence of validity and reliability and to establish a nomological network between the OSCS and similar instruments utilized in the field. The study utilized sequential exploratory factor analysis- confirmatory factor analysis (EFA-CFA) and correlational analysis to assess results of the data. Students enrolled in online courses at higher education institutions located in the United States served as the sample for this study. Three instruments were used during the study. The OSCS was administered first so that the factor structure could be examined for factor validity. Once confirmed, the Classroom Community Scale (CCS) and the Community of Inquiry Scale (COI) served as the instruments to examine nomological validity through correlational analysis of data.This study provided evidence of factor validity and reliability for data from the OSCS. After the initial EFA-CFA, the four-factor structure held, and 16 of the 25 original items remained for nomological testing. Statistically significant correlations were demonstrated between factors contained in the OSCS, CCS, and COI, providing further evidence of construct validity. These results indicate that for the sample used in this study, the OSCS provides data that are valid and reliable for assessing feelings of connection between participants in online courses at institutions of higher learning.
Effects of Child Development Associate Credential System 2.0 on Candidate Success Rates
The purpose of this research was to identify the impact of process changes that have been made to the Child Development Associate (CDA) credential, which is a beginning early childhood teacher credential that focuses on competency based standards widely seen as necessary for early childhood teachers to possess. The process in which early childhood teachers receive their credential changed in 2013 with the implementation of CDA credential 2.0. Changes included taking a computerized exam and the implementation of a professional development specialist conducting an on-site classroom observation. In order to determine the impact that CDA 2.0 had on teacher credentialing success rates, a mixed-method sequential design was employed. First, existing data sets of success rates from a national scholarship program were reviewed. Following, interviews with CDA credential seekers were conducted. Findings revealed that while candidate success rates increased for those receiving CDA credentials under the 2.0 system, the actual number of candidates receiving scholarships to pursue the CDA credential through the national scholarship program decreased. Qualitative analysis of the semi-structured interviews indicated that three areas that impacted CDA 2.0 candidate success rates were the professional education programs and instructors, the CDA Exam, and Professional Development Specialists. This is the first research study to examine the CDA credential process. The findings demonstrate that the 2.0 system provides candidates with necessary supports to be successful. A significant question arising out of the data is how a determination is made to issue a credential. Before QRIS and public policy initiatives employ more efforts to professionalize the field of early childhood – primarily through the CDA credential – the process by which one obtains a credential should be more thoroughly examined.
Small Town Retail Change in East Texas: an Analysis of Retail Growth, Decline, and Spatial Reconfiguration
In recent years, small towns have experienced declining levels of retail activity attributable to a variety of factors. Previously conducted research identifies a number of these factors such as changing population dynamics, continuously evolving retail practices, locational factors, and an assortment of other macroeconomic factors. Although retail decline is common for many small towns, there are some small towns that have been able to maintain their viability in an ever-changing economic climate. The primary purpose of this research is to better understand what spatial and socio-economic characteristics contribute to retail growth and decline in a series of small towns. This research highlights a selection of small towns across a 14 county area within east Texas. The selection of small towns includes a number of towns with an increasing number of retail establishments as well as a number of towns with decreasing retail establishments over the 14 year study timeframe. Contained within this research is a discussion of small town economic and retail development, as well as findings regarding spatial and socio-economic characteristics as they relate to retail growth and decline in small towns. This research finds that locational characteristics do have an effect on retail growth and decline. The research also supports the literature, which states retail growth and decline is more pronounced within certain retail categories.
Self-definition and College Adaptation in Students From the Ronald E. McNair Postbaccalaureate Achievement Program
While a great deal of psychological research is conducted on college students, less has been done on their adaptation to college. These young adults, as they develop ego identity and differentiate themselves from parents and families, must adjust to the social and academic environment of college. Psychosocial adjustment predicts college retention better than academic predictors do. First generation college students face greater than typical challenges adapting to college. The Ronald E. McNair Post-Baccalaureate Achievement Program exists to aid first generation, lower income undergraduate student who wish to pursue a doctoral degree. Self-definition scored from thematic apperceptive technique stories reflects an individual’s relative freedom from social role constraint. This study examined the role of self-definition and familial understanding and acceptance in this population as predictors of successful adaptation to college. While neither was found to be a significant predictor, family understanding and acceptance was found to be a more defining characteristic of this sample than was self-definition. This suggests that when social support is sufficient, individuals do not need to rely on self-definition.
Montesquieu, Diversity, and the American Constitutional Debate
It has become something of a cliché for contemporary scholars to assert that Madison turned Montesquieu on his head and thereafter give little thought to the Frenchman’s theory that republics must remain limited in territorial size. Madison did indeed present a formidable challenge to Montesquieu’s theory, but I will demonstrate in this dissertation that the authors of the Federalist Papers arrived at the extended sphere by following a theoretical pathway already cemented by the French philosopher. I will also show that Madison’s “practical sphere” ultimately concedes to Montesquieu that excessive territorial size and high levels of heterogeneity will overwhelm the citizens of a republic and enable the few to oppress the many. The importance of this dissertation is its finding that the principal mechanism devised by the Federalists for dealing with factions—the enlargement of the sphere—was crafted specifically for the purpose of moderating interests, classes, and sects within an otherwise relatively homogeneous nation. Consequently, the diverse republic that is America today may be exposed to the existential threat anticipated by Montesquieu’s theory of size—the plutocratic oppression of society by an elite class that employs the strategy of divide et impera.
Assessing the Spatial and Temporal Distribution of MTBE and BTEX Compounds in Lake Lewisville, Texas February 1999 - February 2000
The spatial and temporal distribution of Methyl Tertiary-Butyl Ether (MTBE) and BTEX (Benzene, Toluene, Ethylbenzene, Xylenes) compounds were assessed in a multipurpose reservoir, Lake Lewisville, Texas between February 1999 and February 2000. Concentrations of MTBE ranged from 0.0 - 16.7 mg/L. Levels of MTBE in the lake were related to watercraft. BTEX concentrations were never detected above 2.0 mg/L during the sampling period. Finished drinking water from Denton and the Upper Trinity Regional Water District (UTRWD) Treatment Plants were also tested for MTBE and BTEX. MTBE and BTEX were not detected in UTRWD water samples. Denton's finished water samples never exceeded 2.2 mg/L for MTBE and BTEX was not detected except for one replicate of 1.1 mg/L toluene.
Spatial and Temporal Influences of Water Quality on Zooplankton in Lake Texoma
Seventy-one aquatic species including the copepodids and nauplii were identified from Lake Texoma from August 1996 to September 1997. Zooplankton community structure, abundance and spatial and temporal distributions were compared among five lake zones delineated a priori based on chloride concentration. The zones, in order of decreasing chloride concentration, are the Red River zone (RRZ), Red river Transition zone (RRTZ), Main Lake zone (MLZ), Washita River Transition zone (WRTZ) and Washita River zone (WRZ). Bray Curtis Similarity Index showed community structure was most similar in the two Red River arm zones, the two Washita River arm zones and the MLZ. Zooplankton abundance was greatest in the Red River arm (312 org/L), intermediate in the Washita River arm (217 org/L) and least in the Main Lake body (103 org/L). A significant increase in the abundance of a deformed rotifer, Keratella cochlearis, was observed mainly in the Red River arm during a second study from March 1999 to June 1999. Seasonal dynamics, rather than spatial dynamics, were more important in structuring the zooplankton community, especially in the two river arms. Spatial variance was solely attributed to station and zone effects independent of time for a few crustacean species and many of the water quality parameters supporting the presence of longitudinal gradients of differing water quality. Three independent models (Red River arm, Washita River arm, Main Lake body) rather than a single model for the entire reservoir, best describe patterns in the zooplankton community and its relationship to seasonal, physical and chemical factors. Statistical power, sample size and taxonomic resolution were examined. When monitoring seasonal and annuals trends in abundance, the greatest statistical power was achieved by analyzing count data at taxonomic levels above genus. Taxonomic sufficiency was assessed to determine if costs could be reduced for zooplankton identifications. For water quality monitoring ...
