Background: Compared to the general United States (U.S.) population, Arizona counties along the U.S.-Mexico border have a higher prevalence of dental caries, which can be reduced with adequate fluoride exposure. Because of concern regarding local tap water quality, fluoride-free bottled water consumption is common in this region, raising concern that families are not receiving adequate fluoride to promote dental health. Objective: To evaluate the levels of fluoride in tap and bottled water as well as the use of fluoride supplements in an Arizona border community. Methods: Low-income Latino households (n = 90) who report use of bottled water as their primary source of water intake were recruited. Participants completed a questionnaire about their and their children's dental histories and use of fluoride supplements. Water samples (bottled and tap) were collected from a subset of households (n = 30) for analysis of fluoride. Results: Fluoride detection levels were significantly greater (p = 0.02, Fisher's exact test) in tap water (average = 0.49 mg/dL) than in bottled water, yet, the majority (22/30) were below the range for optimal dental health (0.7-1.2 mg/L). Concentration of fluoride in the majority (29/30) of bottled water samples was below the quantitative detection limit of 0.4 mg/L. Children were significantly less likely to have dental caries if they received fluoride varnishing treatments (p = 0.01, Fisher's exact test), lived in households that reported using fluoridated mouthwash (p < 0.001, Fisher's exact test), their parents received fluoride education (p = 0.01, Fisher's exact test), and their parents reported visiting a dentist yearly (p < 0.001, Fisher's exact test). Furthermore, none of the participants reported receiving recommendations from health-care providers about fluoride supplementation or variance in content by the type of water consumed. Conclusion: Although fluoride was significantly more likely to be detected in tap than bottled water, neither water source in this border community is likely to provide enough fluoride for optimal dental health. Low-income children in this region may benefit from regular access to fluoride varnishing treatments and/or use of fluoridated mouthwash, interventions that could be tested in future well-designed trials.

This thesis seeks to promote a clearer understanding of relationships between trade liberalization and environmental quality in a free trade zone along an international border, between countries unevenly matched in development and infrastructure. Specifically, it examines whether theories of environmental degradation provide appropriate models for explaining the impact of NAFTA on the environment in the Paso del Norte. The relationship between trade liberalization and environmental quality is examined through an analysis of environmental indicators in the decade preceding and following NAFTA. Finally, the role of environmental governance is addressed, especially the intricacies involved in multi-jurisdictional governance of the environment. The research indicates that trade liberalization is not necessarily environmentally harmful. The data suggest that NAFTA had little to no direct negative impact on the region's environmental condition, but they also do not provide evidence that NAFTA improved the environment. One factor that could have helped to limit its effects may be local, interstate, and international initiatives that improved the health of the ecosystem along the border before NAFTA was even conceived. Another factor is the environmental governance in place before and after NAFTA. Thus, it may be beneficial for trade liberalization agreements to address environmental concerns as integral parts of the negotiations, and to set requirements for meeting infrastructure demands, as the agreements are implemented. Furthermore, it is important that international environmental institutions established to monitor environmental cooperation be more closely associated with the trade cooperation organizations and be given the authority needed to complete their directives more effectively. / Master of Arts

Water resource management is a multifaceted issue that becomes more complex when considering multiple nations’ interdependence upon a single shared transboundary river basin. With over 200 transboundary river basins worldwide shared by two or more countries, it is important to develop tools to allow riparian countries to cooperatively manage these shared and often limited water resources. Cooperative game theory provides tools for determining if cooperation can exist across jurisdictional boundaries through a suite of mathematical tools that measure the benefits of cooperation among basin stakeholders. Cooperative game theory is also useful for transboundary negotiation because it provides a range of solutions which will satisfy all players in the game and provides methods to fairly and equitably allocate the gains of that cooperation to all participating stakeholders, if that cooperation is shown to be possible. This dissertation applies cooperative game theory concepts to the Rio Grande/Bravo basin in North America as a case study. The Rio Grande/Bravo forms the 1,200 km border between the United States and Mexico. A comprehensive water resources planning model was developed for the basin including the major water users, water related infrastructure including reservoirs, and water policy logic related to the bi-national water sharing agreements. The water planning model is used to calculate the characteristic functions for the cooperative game analysis. For the Water Demand Reduction Game, the largest agricultural users, District 005, District 025 and the Texas Watermaster Section below Falcon were defined individual players. The cooperative analysis was between the individual players rather than the countries. In addition to the cooperative analysis, performance measures for water deliveries were calculated to determine if water delivery was improved to each player under the cooperative game. The results show that the amount of additional water to the downstream players may not be large enough to induce cooperation. The small amount of increase in water deliveries is related to the large system losses as the water travels downstream over a long distance and a division of water under the 1944 Treaty between the United States and Mexico. / text

This study analyzed trends in access and success of students admitted through the Top 10% admissions policy. The study employs a comparative analysis between public universities from the Borderland region and the two top-tier public universities in Texas. This Texas admissions policy provides students in the top 10% of their graduating high school class admission to any state 4-year public university. Therefore, this policy implies that being a top 10% student equates to being college ready for any public university in Texas, regardless of selectivity or top tier status. Research on the Texas Top 10% policy has focused on its success in improving diversity and student performance at the two top-tier public universities in Texas, The University of Texas at Austin and Texas A&M University. However, enrollment disparity continues at these elite institutions between Whites, Latina/os and Blacks. Additionally, the Texas Borderland region is an intersection of large Latina/o demographics; distance from top-tier institutions; and great disparities in economic development, health, and education. Combining the aforementioned conditions, we know little about the access and success of Borderland top 10% students, particularly in comparing the two public top tier universities in Texas to the alternative choice of their local Borderland university. This study used mixed methods to compare the trends in access and success of Borderland students admitted under the Top 10% admissions policy at Borderland universities and at top-tier public universities, and additionally controlled for student characteristics in explaining student persistence and graduation. The quantitative analysis used student-level descriptive and inferential statistics with data facilitated by Texas Higher Education Coordinating Board. The qualitative section of this dissertation used focus-group interviews with 36 students at 5 Borderland universities and 1 top-tier university to explain their success. This study applies Bourdieu's theoretical framework of social and cultural capitals and habitus to interpret the findings. Results indicated student differentiation between institutions in access, success, and explanations. Ethnicity, gender, family income, and college generation status influence differences in enrollment between institutions, in which all together influenced differences in graduation and persistence. On the other hand, the interviews revealed that personal effort and institutional resources also explained differences in student success. This study provides implications for further research and policy considerations. / text

Effective doctor-patient communication is critical to improving health outcomes. Good communication improves emotional health, symptom resolution, functional and physiologic status, and pain control. Conversely, ineffective communication leads to misdiagnosis, inappropriate treatment poor adherence, misuse of health services, and high patient stress. In the U.S., Hispanics are the fastest growing minority. Despite the high burden of illness among this population, Hispanics are less likely than other minorities to regularly see a health professional. This is explained in part because Hispanics navigate a health system designed for the majority, experience a mismatch between cultural values and health beliefs, and have limited English proficiency. These communication challenges contribute to health disparities among the Hispanic population living in the U.S. Despite the importance of doctor-patient communication, few communication interventions that focus on improving patient skills have been tested in this population. Therefore, the purpose of this study was to evaluate whether a patient communication intervention tailored for female Hispanic patients could be practically implemented in a practice setting. The first aim focused on adapting existing communication skills training tools for a Hispanic population. The second aim assessed the feasibility of implementing the training tool in a federally qualified health center in a US-Mexico border community. The third aim explored the extent to which trained patients were able to integrate the information provided. Results indicate that it is feasible to implement communication training when delivered by clinical staff. Patient follow-up revealed that patients valued training on how to communicate with their doctor the most. Moreover, it is feasible to sustain the intervention when it is aligned with the priorities of the clinical site. Patient communication training in medically underserved rural areas could improve barriers to improved health outcomes in communities with a high prevalence of Hispanic patients. Future funding is needed to further test, dissemination of communication training programs.

Chicana Literature: A Feminist Perspective of Gloria Anzaldúa's Identity Politics Doctoral Thesis Mgr. et Mgr. Tereza Jiroutová Kynčlová 2017 ABSTRACT In the analyses executed in the present doctoral thesis, Chicana literary production emerges as a complex example of a strategic and reflexive instrumentalization of literature in the form of a political and activist tool contributing to Chicanas' gender and cultural emancipation on the one hand. On the other hand, within the Chicana/o context, literature is employed for perfecting the politics of recognition of the marginalized nation typified by the specificity of its geographic, cultural, and social location on the U.S.-Mexico border where a plethora of socially constructed categories interact and intersect. The doctoral thesis further provides a gender analysis of literary representations of Chicana/o lived experience by Chicana feminist writers in general and by Gloria Anzaldúa in particular, and investigates how these representations help shape feminist thought not only in relation to the U.S.-Mexico borderlands, but within and beyond the United States. Moreover, the thesis supplies an interpretation of Anzaldúa's reconceptualization of the border concept as a pertinent means for comprehending Chicanas'/os' socio-cultural context and for forging a...

This study has for its goal to examine whether a new racist prejudice against Mexican illegal immigrants was driving the activities of the minutemen movement operating along the U.S.- Mexico border whose stated goal was to prevent illegal immigrants from entering the country. This work assumes that the old blatant racism is no longer acceptable within society but was replaced by a conspicuously color-blind rhetoric, typical of the minutemen movement, that might harbor a new racist prejudice. New racism does not put forth a race defined biologically but understands the white and non-white races conceptually. It thus contributes to the maintenance of the white-black dichotomy within society and more importantly to the discrimination and exclusion of the non-white races. In order to disclose a possible racist prejudice, this study conducts a Critical Discourse Analysis of the minutemen's discourse. Results of this analysis show that especially the focus on the notion of law and order, so typical of the discourse, is hugely misleading and that under this seemingly color-blind reasoning, there is, indeed, a hidden expression of the new racist prejudice.

In the early 1990s, a series of gruesome murders of young women in Ciudad Juárez, a city located in the U.S.-Mexico border, shook the political landscape of Mexico. A decade later, the strange and violent murders, known as the feminicides or feminicidios of Juárez, reached international infamy across hemispheres and continents. During this time, the city and the cases became the subjects of an extensive body of scholarship and of any imaginable artistic medium (narrative, poetry, theater, performance, music, and so on). Eventually, the complexity and overexposure of the cases and the sociopolitical conditions of Ciudad Juárez placed them at the center of a paradoxical debate: on one hand, the work of activists, feminists, and scholars of social sciences (like anthropologists and sociologists) studied the murders as a localized example of a larger phenomenon of mysoginistic violence; on the other, journalistic and media investigations of Juárez understood the murders as the products of specific agents (serial killers, murderers, drug cartels, amongst others) and the fractures within the Mexican Nation-State. And yet, despite the expansion and overlapping of these discourses, fictional representations of Juárez remained tangential to this intricate debate. Thus, this research explores the different ways in which writers, artists, and filmmakers deployed and negotiated existent perspectives on the feminicides within fictional environments. As a result of the vast amount of published work available on Ciudad Juárez, I narrowed the objects of my research through a transnational scope. The resulting sample of texts transverses borders (Mexico and the U.S.), continents (Latin America and Europe), genres (fiction and nonfiction), and mediums (literature and film). The first chapter explores the connections of Sergio González Rodríguez’s Huesos en el desierto and Roberto Bolaño’s 2666 through the theoretical framework of the possible worlds of fiction. The second chapter moves to issues of representation, gender, and race through the analysis of two novels written by Chicana scholars: Alicia Gaspar de Alba’s Desert Blood: The Juárez Murders and Stella Pope Duarte’s If I Die in Juárez. Finally, the third chapter focuses on film representations of Juárez and the feminicides in the form of Gregory Nava’s Bordertown and Carlos Carrera’s Backyard/El Traspatio. / text
