Description
This is a study that tests the New Urbanist claims that neighborhood design impacts sense of community and residential habits. Through the framework provided by New Urbanist theories, a social survey is used to examine residential perception and behavior among three fringe neighborhoods in southeast Tucson, each representing a different approach to neighborhood design: New Urbanist, traditional suburban, and a hybrid variety. The primary relationships studied are between neighborhood design and use of public space, neighborhood design and travel habits, and neighborhood design and sense of community. The findings show that the New Urbanist community does support the highest levels of sense of community and use of public space, but conclusions cannot be drawn concerning the relationship between sense of community and travel behavior, especially non-vehicular travel to public space. While these results are inconclusive concerning the direct impact of the neighborhood type on certain behaviors and perceptions, the findings support the notion that a New Urbanist design does indeed enhance social interactions and use of public space. It also offers insight into the importance of residential preferences, not as much towards walkability but towards general environmental concern.

Description
This study explores the potential risks associated with the 65 U.S.-based commercial nuclear power plants (NPPs) and the distribution of those risks among the populations of both their respective host communities and of the communities located in outlying areas. First, I examine the relevant environmental justice issues. I start by examining the racial/ethnic composition of the host community populations, as well as the disparities in socio-economic status that exist, if any, between the host communities and communities located in outlying areas. Second, I estimate the statistical associations that exist, if any, between a population's distance from a NPP and several independent variables. I conduct multivariate ordinary least square (OLS) regression analyses and spatial autocorrelation regression (SAR) analyses at the national, regional and individual-NPP levels. Third, I construct a NPP potential risk index (NPP PRI) that defines four discrete risk categories--namely, very high risk, high risk, moderate risk, and low risk. The NPP PRI allows me then to estimate the demographic characteristics of the populations exposed to each so-defined level of risk. Fourth, using the Palo Verde NPP as the subject, I simulate a scenario in which a NPP experiences a core-damage accident. I use the RASCAL 4.3 software to simulate the path of dispersion of the resultant radioactive plume, and to investigate the statistical associations that exist, if any, between the dispersed radioactive plume and the demographic characteristics of the populations located within the plume's footprint. This study utilizes distributive justice theories to understand the distribution of the potential risks associated with NPPs, many of which are unpredictable, irreversible and inescapable. I employ an approach that takes into account multiple stakeholders in order to provide avenues for all parties to express concerns, and to ensure the relevance and actionability of any resulting policy recommendations.

Description
Using integrated threat theory as the theoretical framework, this study examines the impact of perceived realistic threats (threats to welfare) and symbolic threats (threats to worldview) on anti-immigrant sentiment among a nationally representative sample in the U.S. Analysis of the antecedents of prejudice is particularly relevant today as anti-immigrant sentiment and hostile policies toward the population have risen in the past two decades. Perceived discrimination has also become salient within immigrant communities, negatively impacting both mental and physical health. Using logistic ordinal regressions with realistic threat, symbolic threat, and immigrant sentiment scales, this study found that both realistic and symbolic threats increased participants' likelihood of selecting a higher level of anti-immigrant sentiment, suggesting both are predictive of prejudice. However, symbolic threats emerged as a greater predictor of anti-immigrant sentiment, with an effect size over twice that of realistic threats. Implications for social work policy, practice, and future research are made.

Description
Based on the Foucauldian understanding that sexuality discourse operates as a powerful instrument for the regulation of societies and individuals, this research considers how internalized gender and sexuality discourses affect young women's embodied experiences of masturbation, and more broadly their sexual subjectivity and health. Drawing on interdisciplinary feminist perspectives on gender, sexuality, health, and embodiment, I examine female sexual health within a positive rights framework. That is, I view the rights to both sexual safety and pleasure as essential components of female sexual health, and conceptualize girls and young women as potential sexual agents. By asking young women about their lived experiences of self-pleasure, this research challenges not only the historical legacy of pathologizing female desire and pleasure, but also scholars' tendency to construct female sexuality solely in a heteronormative, partnered context. Based on focus groups, interviews, journals, and questionnaires collected from 109 female college students from diverse ethnic, religious, and sexuality backgrounds in Arizona and Michigan, I employ grounded theory to analyze individual feelings and experiences in the context of larger societal discourses. My findings indicate that when girls internalize negative discourses about masturbation (e.g. as sin or secular stigma), general heteronormative sexuality discourses, and a silence around female self-pleasure, there are severe negative consequences for how they understand and experience masturbation. I argue that they engage in sexual self-surveillance that often results in emotional and physical struggles, as well as the re-inscription of hegemonic cultural discourses on female masturbation, bodies, desire, and pleasure. By illustrating how even the most private and `invisible' behavior of masturbation can become a site for regulating female sexuality, this research provides important evidence of the power of increasingly covert mechanisms to govern gendered bodies and subjectivities through self-surveillance. Alternatively, this research also highlights the potential of normalizing self-pleasure for increasing girls' and young women's capacity for resisting oppressive gender and sexuality discourses and behaviors, developing an agentic sexual subjectivity, and feeling sexually empowered. Thus, this research also has practical implications for conceptualizing sexual health for girls and young women in a way that includes the rights to sexual safety and pleasure.

Description
The objective of this dissertation is to investigate the association of mother's autonomy and male labor migration with child's health and education, taking into account possible differences by child's gender. The dissertation uses data from a household longitudinal survey conducted in rural southern Mozambique in 2006, 2009 and 2011 to address three main questions: 1) Is decision-making autonomy associated with child's schooling and child mortality? 2) Is father's labor migration associated with children's health outcomes? 3) If so, do these relationships change by gender of the child? The dissertation makes three main contributions to the literature. First, it finds a significant effect of mother's decision-making autonomy on child's outcomes, independent of other characteristics related to women's status. Second, it illustrates the cumulative nature of the effect of father's labor migration on the health of children left behind. And finally, the dissertation shows that women's decision-making autonomy and male migration affect children's outcomes differently depending on the gender of the child and on the outcome being analyzed. The dissertation is structured in five chapters. The first chapter gives an introductory overview of women's autonomy and male migration as determinants of children's outcomes, and presents the setting. The second chapter examines the relationship between mother's decision-making autonomy and enrollment for primary school-age children. Results show a positive association of women's decision-making autonomy with the probability of being enrolled for daughters, but not for sons. The effect of women's decision-making autonomy is net of other characteristics associated with autonomy. The third chapter analyzes the association of mother's decision-making autonomy and under-five child mortality. Results show a positive effect women's decision-making autonomy for sons' survival chances. The fourth chapter examines the effect of father's labor migration on health of children left behind. Results indicate that a proportion of child's life spent away by the father has a negative effect on the child's chances of being stunted but that it also decreases the likelihood of the child receiving age-adequate immunization. These results are gendered as the effect of father's migration on both outcomes is significant only for daughters. Chapter five presents the concluding remarks.

Description
Over the past few decades, businesses globally have advanced in incorporating the principles of sustainability as they strive to align economic outcomes with growing and complex social and environmental demands and opportunities. This transition is conditioned by the maturity, scale, and geographical location of a business (among other factors), with particular challenges placed on small enterprises in middle- to low-income communities. Within this context, the overarching research question of this dissertation is why and how business incubation processes may foster sustainable enterprises at the middle and base of the socioeconomic pyramid (MoP/BoP). To explore this question, in this project I used as a case study the experience of a network of social business incubators operated by Tecnologico de Monterrey, a private, non-profit, multi-campus university system in Mexico. Centering on its campus in Guadalajara and in order to understand if and how MoP/BoP businesses address sustainability, I developed a current state assessment of incubator processes, analyzing during two semesters the activities of incubated entrepreneurs and their goals, motivations, and outcomes. The general expectation at the outset of the study was that Tec's social business incubation process, in both its design and implementation, focuses on the economic viability and outcomes of incubated projects and hence does not promote entrepreneur commitment to sustainability goals and practices. The general approach of the research project involved a qualitative, in-depth ethnographic assessment of participants. Data were collected by means of the following research tools: (a) archival and documentary review, (b) participant observation, (c) surveys of participants (entrepreneurs and advisors/mentors), and (d) semi-structured interviews of participants. The overall design of the research was inspired by the transitions management approach and by the intervention research method, while qualitative results were assessed under the grounded theory approach. Results of the research are reported under three general categories: (a) analysis of entrepreneur goals, motivations, and outcomes, (b) identification of social and environmental opportunities, and (c) review of the role of social networks and broader support structures. While results confirmed the general expectation of the study, it was possible to establish (based on the interaction with the entrepreneurs and other actors) that there is both interest and commitment to identify and explore opportunities in social and environmental issues. Thus, the dissertation concludes with a proposal for potential future interventions in this social incubator, exploring a new vision and strategies for a transition to a more sustainability-oriented approach. Finally, key recommendations define the most critical elements of an agenda for transition in the social incubation process at Campus Guadalajara and provide input for other efforts.

Description
Research on priming has shown that exposure to the concept of fast food can have an effect on human behavior by inducing haste and impatience (Zhong & E. DeVoe, 2010). This research suggests that thinking about fast food makes individuals impatient and strengthens their desire to complete tasks such as reading and decision making as quickly and efficiently as possible. Two experiments were conducted in which the effects of fast food priming were examined using a driving simulator. The experiments examined whether fast food primes can induce impatient driving. In experiment 1, 30 adult drivers drove a course in a driving simulator after being exposed to images by rating aesthetics of four different logos. Experiment 1 did not yield faster driving speeds nor an impatient and faster break at the yellow light in the fast food logo prime condition. In experiment 2, 30 adult drivers drove the same course from experiment 1. Participants did not rate logos on their aesthetics prior to the drive, instead billboards were included in the simulation that had either fast food or diner logos. Experiment 2 did not yielded faster driving speeds, however there was a significant effect of faster breaking and a higher number of participants running the yellow light.

Description
As a form of bodily modification, female circumcision has generated unprecedented debates across the medical community, social sciences disciplines, governmental
on-governmental agencies and activists and others. The various terminologies used to refer to it attest to differences in knowledge systems, perceptions, and lived experiences emerging from divergent cultures and ideologies. In the last two decades, these debates have evolved from a local matter to a global health concern and human rights issue, coinciding with the largest influx of African refugees to the Western nations. Various forms of female circumcision are reported in 28 countries in the African Continent; Somalia has one of the highest prevalence of female circumcision and the most severe type. The practice is antithetical to Western values and poses an ideological challenge to the construction of the normal body, its bodily processes and its existential being-in-the-world. From the global health perspectives, female circumcision is deemed to be a health hazard--especially during childbirth--though the scientific evidence is inconclusive from studies conducted in post-migration. Yet, Somali refugee women have higher childbearing disparities in host nations, including the U.S. They are also perceived as difficult patients and resistant to obstetrics interventions. Although their FGC status and "cultural" differences are often cited, there is a lack of adequate explanations as to why and how these factors shape patient-provider interactions and affect outcomes. The objectives of this dissertation study are to quantitatively and qualitatively explore these questions within and between Somali refugee women and their healthcare providers in Arizona. Two theoretical frameworks and methods--culture consensus and embodiment-- are applied to identify variations in childbearing knowledge and to explore how the cultural phenomenon of circumcision is subjectively and intersubjectively embodied in the context of childbearing. Culture consensus questionnaire (N=174) and ethnographic interviews (N=40) using phenomenology approach were conducted. Analyses suggest cross-cultural disagreement hinged on: faith in science versus God, pregnancy/childbirth interventions, language challenges, and control-resistance issues; intra-cultural disagreement underscores that Somalis are not culturally homogenous group. Preconceptions of female circumcision body as a cultural phenomenon has different and conflicting meanings that may adversely impact patient-provider interactions and outcomes.

Description
The National Research Council 2011 report lists quantifying the extent of de facto (or unplanned) potable reuse in the U.S. as the top research need associated with assessing the potential for expanding the nations water supply through reuse of municipal wastewater. Efforts to identify the significance and potential health impacts of de facto water reuse are impeded by out dated information regarding the contribution of municipal wastewater effluent to potable water supplies. This project aims to answer this research need. The overall goal of the this project is to quantify the extent of de facto reuse by developing a model that estimates the amount of wastewater effluent that is present within drinking water treatment plants; and to use the model in conjunction with a survey to help assess public perceptions. The four-step approach to accomplish this goal includes: (1) creating a GIS-based model coupled with Python programming; (2) validating the model with field studies by analyzing sucralose as a wastewater tracer; (3) estimating the percentage of wastewater in raw drinking water sources under varying streamflow conditions; (4) and assessing through a social survey the perceptions of the general public relating to acceptance and occurrence of de facto reuse. The resulting De Facto Reuse in our Nations Consumable Supply (DRINCS) Model, estimates that treated municipal wastewater is present at nearly 50% of drinking water treatment plant intake sites serving greater than 10,000 people (N=2,056). Contrary to the high frequency of occurrence, the magnitude of occurrence is relatively low with 50% of impacted intakes yielding less than 1% de facto reuse under average streamflow conditions. Model estimates increase under low flow conditions (modeled by Q95), in several cases treated wastewater makes up 100% of the water supply. De facto reuse occurs at levels that surpass what is publically perceived in the three cities of Atlanta, GA, Philadelphia, PA, and Phoenix, AZ. Respondents with knowledge of de facto reuse occurrence are 10 times more likely to have a high acceptance (greater than 75%) of treated wastewater at their home tap.

Description
This qualitative study examines the major changes in relationship closeness of married couples when one spouse acquires a vision disability. Turning Points analysis and Retrospective Interview Technique (RIT) were utilized which required participants to plot their relational journey on a graph after the onset of the disability. A sample of 32 participants generating 100 unique turning points and 32 RIT graphs lent in-depth insight into the less explored area of the impact of a visual disability on marital relationships. A constant comparison method employed for the analysis of these turning points revealed six major categories, which include Change in Relational Dynamics, Realization of the Disability, Regaining Normality in Life, Resilience, Reactions to Assistance, and Dealing with the Disability. These turning points differ in terms of their positive or negative impact on the relational closeness between partners. In addition, the 32 individual RIT graphs were also analyzed and were grouped into four categories based on visual similarity, which include Erratic Relational Restoration, Erratic Relational Increase, Consistent Closeness and Gradual Relational Increase. Results provide theoretical contributions to disability and marriage literature. Implications for the application of turning points to the study of post-disability marital relationships are also discussed, and research directions identified.
