Description
This dissertation explores vulnerability to extreme heat hazards in the Maricopa County, Arizona metropolitan region. By engaging an interdisciplinary approach, I uncover the epidemiological, historical-geographical, and mitigation dimensions of human vulnerability to extreme heat in a rapidly urbanizing region characterized by an intense urban heat island and summertime heat waves. I first frame the overall research within global climate change and hazards vulnerability research literature, and then present three case studies. I conclude with a synthesis of the findings and lessons learned from my interdisciplinary approach using an urban political ecology framework. In the first case study I construct and map a predictive index of sensitivity to heat health risks for neighborhoods, compare predicted neighborhood sensitivity to heat-related hospitalization rates, and estimate relative risk of hospitalizations for neighborhoods. In the second case study, I unpack the history and geography of land use/land cover change, urban development and marginalization of minorities that created the metropolitan region's urban heat island and consequently, the present conditions of extreme heat exposure and vulnerability in the urban core. The third study uses computational microclimate modeling to evaluate the potential of a vegetation-based intervention for mitigating extreme heat in an urban core neighborhood. Several findings relevant to extreme heat vulnerability emerge from the case studies. First, two main socio-demographic groups are found to be at higher risk for heat illness: low-income minorities in sparsely-vegetated neighborhoods in the urban core, and the elderly and socially-isolated in the expansive suburban fringe of Maricopa County. The second case study reveals that current conditions of heat exposure in the region's urban heat island are the legacy of historical marginalization of minorities and large-scale land-use/land cover transformations of natural desert land covers into heat-retaining urban surfaces of the built environment. Third, summertime air temperature reductions in the range 0.9-1.9 °C and of up to 8.4 °C in surface temperatures in the urban core can be achieved through desert-adapted canopied vegetation, suggesting that, at the microscale, the urban heat island can be mitigated by creating vegetated park cool islands. A synthesis of the three case studies using the urban political ecology framework argues that climate changed-induced heat hazards in cities must be problematized within the socio-ecological transformations that produce and reproduce urban landscapes of risk. The interdisciplinary approach to heat hazards in this dissertation advances understanding of the social and ecological drivers of extreme heat by drawing on multiple theories and methods from sociology, urban and Marxist geography, microclimatology, spatial epidemiology, environmental history, political economy and urban political ecology.

Description
Immigration courts fail to live up to courtroom ideals. Around 2009, proposals were offered to address the problems of these troubled courts. My study illustrates the inevitable linkage between court reform proposals and conceptions of fairness and efficiency, and ultimately justice. I ask: (1) From the perspective of attorneys defending immigrants' rights, what are the obstacles to justice? How should they be addressed? And (2) How do proposals speak to these attorneys' concerns and proposed resolutions? The proposals reviewed generally favor restructuring the court. On the other hand, immigration (cause) lawyers remain unconvinced that current proposals to reform the courts' structure would be successful at addressing the pivotal issues of these courts: confounding laws and problematic personnel. They are particularly concerned about the legal needs and rights of immigrants and how reforms may affect their current and potential clients. With this in mind, they prefer incremental changes - such as extending pro bono programs - to the system. These findings suggest the importance of professional location in conceptualizing justice through law. They offer rich ground for theorizing about courts and politics, and justice in immigration adjudication.

Description
This thesis examines the Mexican federal judiciary and the problem of corruption in this institution, particularly related to cases of drug trafficking. Given the clandestine nature of corruption and the complexities of this investigation, ethnographic methods were used to collect data. I conducted fieldwork as a "returning member" to the site under study, based on my former experience and interaction with the federal judicial system. I interviewed 45 individuals who work in the federal courts in six different Mexican cities. I also studied case files associated with an important criminal trial of suspected narco-traffickers known in Mexico as "El Michoacanazo." My study reveals the complicated nature of judicial corruption and how it can occur under certain circumstances. I conclude that the Mexican federal judiciary has become a more professional, efficient, and trustworthy institution over the past fifteen years, though institutionalized practices such as nepotism, cronyism, personal abuse of power, and gender inequalities still exist, tending to thwart the full professionalization of these courts and facilitating instances of misconduct and corruption. Although structural factors prevent full professionalization and corruption does occur in these courts, the system works better than it ever has before.

Description
Residents of the United States increasingly support organic and local food systems. New Social Movement theorists have described alternative agriculture as a social movement that transcends social class. Other scholars have critiqued alternative agriculture for catering to a middle-class, white public. Simultaneously, geographers have identified communities across the United States that struggle with reduced access to healthy fruits and vegetables. In some of these neighborhoods, known as “food deserts,” local groups are redefining an inequitable distribution of healthy food as a social injustice, and they have begun initiatives to practice “food justice.” The overarching research questions of this study are: 1) How do communities become food deserts? 2) How do food justice movements crystallize and communities practice food justice? 3) What are the social outcomes of food justice movements? Using an Ecology of Actors framework, this study analyzes the actors and operational scales of three food justice movements in Phoenix, Arizona. A narrative analysis of historical scholarly materials and other artifacts reveals that, for more than a century, some communities have tried to create minority-operated local food systems. However, they were thwarted by racist policies and market penetration of the conventional US food system. Interviews with residents, garden organizers and food justice advocates living and working in the city create a narrative of the present day struggle for food justice. Results of this work show that contemporary residents describe their foodscape as one of struggle, and carless residents rely upon social networks to access healthy food. Garden organizers and gardeners are creating networks of community gardens, market gardens, and informal farmers’ markets. They are actively transforming their communities’ landscapes with sophisticated garden ecology in an intense urban heat island. However, the movement’s continued success may be threatened. Many new Phoenix-based local food coalitions and national alternative agriculture social movements are now working to alter Phoenix’s foodscape. Composed of well-educated professionals, who have adopted a justice-based language around food, these organizations may unintentionally co-opt the local food justice movements.

Description
Risk assessment instruments play a significant role in correctional intervention and guide decisions about supervision and treatment. Although advances have been made in risk assessment over the past 50 years, limited attention has been given to risk assessment for domestic violence offenders. This study investigates the use of the Domestic Violence Screening Inventory (DVSI) and the Offender Screening Tool (OST) with a sample of 573 offenders convicted of domestic violence offenses and sentenced to supervised probation in Maricopa County, Arizona. The study has two purposes. The first is to assess the predictive validity of the existing assessment tools with a sample of domestic violence offenders, using a number of probation outcomes. The second is to identify the most significant predictors of probation outcomes. Predictive validity is assessed using crosstabulations, bivariate correlations, and the Receiver Operating Characteristic (ROC) curve. Logistic regression is used to identify the most significant predictors of probation outcomes. The DVSI and the OST were found to be predictive of probation outcomes and were most predictive of the outcomes petition to revoke filed, petition to revoke filed for a violation of specialized domestic violence conditions, and unsuccessful probation status. Significant predictors include demographics, criminal history, current offense, victim characteristics, static factors, supervision variables and dynamic variables. The most consistent predictors were supervision variables and dynamic risk factors. The supervision variables include being supervised on a specialized domestic violence caseload and changes in supervision, either an increase or decrease, during the probation grant. The dynamic variables include employment and substance abuse. The overall findings provide support for the continued use of the DVSI and the OST and are consistent with the literature on evidence-based practices for correctional interventions. However, the predictive validity of the assessments varied across sub-groups and the instruments were less predictive for females and offenders with non-intimate partner victims. In addition, study variables only explained a small portion of the variation in the probation outcomes. Additional research is needed, expanding beyond the psychology of criminal conduct, to continue to improve existing risk assessment tools and identify more salient predictors of probation outcomes for domestic violence offenders.

Description
This dissertation examines how violent fantasizing influences the behavior of a brutal sub-class of murderers--mass and serial killers. Specifically, fantasy gives the perpetrator a profane catharsis due to his or her inability to cope with reality. The researcher identified, four common fantasy scripts: (Revenge Fantasy; Sexual, Sadistic and Misogynistic Fantasy; Suicidal-Homicidal Ideation; and Search for Validation through Infamy and Media Attention Fantasy) that more or less, play into the motivations and actions of mass and serial killers. Thus, it is important to understand why and how the killer moves from an all-consuming imaginative space to actually harming others. The methodology used for this research was "ethnographic content analysis" and, to a lesser extent, empirical phenomenology and semiotics. Source materials that were analyzed included: artifacts generated by the offenders prior to commission of their crimes (e.g., diaries, manifestos, blogs, drawings, photographs, and videotapes); official findings of governmental review panels; other public documents; survivor, witness or family accounts; news reports; and work conducted previously by other academics. This dissertation is particularly novel, in that the role of fantasy has not received much critical analysis with respect to mass murder. Likewise, the researcher's examination of current theory on the ontogenesis of moral dysfunction led to an original interpretation in the works of criminologists, Eric Hickey and Lonnie Athens. From a synthesis of Hickey's trauma-control theory and Athens' esoteric constructs of "self" and "other" a more cohesive understanding of the homicidal personality emerged. Essentially, the researcher argues that the intersection of early derailing influences and pervasive life losses result in a fragmented concept of self, which the now deeply unstable individual seeks to validate through violent fantasy and homicidal acts. It is further proposed that these findings may lead to future inquiry into: methods for early intervention and diversion of an at-risk population; and where the foregoing is impractical, better methods of detecting, mitigating the harm caused by and quickly apprehending these particularly violent offenders.

Description
The United States prison population is rapidly rising. Consequently, more families are losing loved ones to the system. While many researchers have focused on women of incarcerated men and children of incarcerated parents, none have looked at the partners of incarcerated women. This paper explores the issues and challenges of prison visitation for the significant others of women incarcerated at Perryville Prison in Goodyear AZ. It is known that prison visitation is important for supporting and maintaining romantic relationships. It is also beneficial to the prison institution. Visitation assists in social control and high inmate morale; both of which lower the instances of violent acts. However, it has been reported that visitation is a daunting task for the visitors. Many sources of information and data were used for this study; formal and informal interviews with family members and others with prison visitation experience, government websites that contain visitation policies, online forums for family and friends of inmates to discuss their concerns, existing research literature, direct observations, and discussions with scholar experts and prison activists. These resources act as a window to visitation at Perryville. With insights derived from symbolic interactionism and previous research guiding the project, it was found that visitation is a good experience for the significant others, incarcerated women, and Perryville. However, the troubles the significant others have with money, the institution and social support strongly suggest that these men encounter hurdles that make the positive act of visitation at times nearly impossible.

Description
This research is about urban homeless people's vulnerability to extreme temperatures and the related socio-spatial dynamics. Specifically, this research investigates heat related coping strategies homeless people use and how the urban environment setting impacts those coping strategies. Semi-structured interviews were conducted with homeless people in Phoenix, Arizona during the summer of 2010. The findings demonstrate that homeless people have a variety of coping strategies and the urban environment setting unjustly impacts those strategies. The results suggest a need for further studies that focus spatial environmental effects on homeless people and other vulnerable populations.

Description
Environmental hazards and disaster researchers have demonstrated strong associations between sociodemographic indicators, such as age and socio-economic status (SES), and hazard exposures and health outcomes for individuals and in certain communities. At the same time, behavioral health and risk communications research has examined how individual psychology influences adaptive strategies and behaviors in the face of hazards. However, at present, we do not understand the explanatory mechanisms that explain relationships between larger scale social structure, individual psychology, and specific behaviors that may attenuate or amplify risk. Extreme heat presents growing risks in a rapidly warming and urbanizing world. This dissertation examines the social and behavioral mechanisms that may explain inequitable health outcomes from exposure to concurrent extreme heat and electrical power failure in Phoenix, AZ and extreme heat in Detroit, MI. Exploratory analysis of 163 surveys in Phoenix, AZ showed that age, gender, and respondent’s racialized group identity did not relate to thermal discomfort and self-reported heat illness, which were only predicted by SES (StdB = -0.52, p < 0.01). Of the explanatory mechanisms tested in the study, only relative air conditioning intensity and thermal discomfort explained self-reported heat illness. Thermal discomfort was tested as both a mechanism and outcome measure. Content analysis of 40 semi-structured interviews in Phoenix, AZ revealed that social vulnerability was associated with an increase in perceived hazard severity (StdB = 0.44, p < 0.01), a decrease in perceived adaptation efficacy (StdB = -0.38, p = 0.02), and an indirect increase (through adaptive efficacy) in maladaptive intentions (StdB = 0.18, p = 0.01). Structural equation modeling of 244 surveys in Phoenix, AZ and Detroit, MI revealed that relationships between previous heat illness experience, perceived heat risk, and adaptive intentions were significantly moderated by adaptive capacity: high adaptive capacity households were more likely to undertake adaptive behaviors, and those decisions were more heavily influenced by risk perceptions and previous experiences. However, high adaptive capacity households had lower risk perceptions and fewer heat illness experiences than low adaptive capacity households. A better understanding of the mechanisms that produce social vulnerability can facilitate more salient risk messaging and more targeted public health interventions. For example, public health risk messaging that provides information on the efficacy of specific adaptations may be more likely to motivate self-protective action, and ultimately protect populations.
