Description
The sacred San Francisco Peaks in northern Arizona have been at the center of a series of land development controversies since the 1800s. Most recently, a controversy arose over a proposal by the ski area on the Peaks to use 100% reclaimed water to make artificial snow. The current state of the San Francisco Peaks controversy would benefit from a decision-making process that holds sustainability policy at its core. The first step towards a new sustainability-focused deliberative process regarding a complex issue like the San Francisco Peaks controversy requires understanding the issue's origins and the perspectives of the people involved in the issue. My thesis provides an historical analysis of the controversy and examines some of the laws and participatory mechanisms that have shaped the decision-making procedures and power structures from the 19th century to the early 21st century.

Description
In The Archive and the Repertoire, Diana Taylor discusses how performance, gestures, resistances within a community holds an embodied memory and enacts the transmission of knowledge within that community. Taylor discusses how this embodied memory is alternative to the written archive of history, history of interaction, history of meaning, history of language. Through the consideration of performance, Taylor urges her reader to reconsider oral and performative transmission of culture, knowledge, customs, traditions, and resistance. This project considers whether this reconsideration can be extended or expanded to oral and performative transmission of law within a community. Specifically, this research explores the conflict between the project of nationality and the reality of social organizing on a community/collective level. It asserts that this conflict is manifested most dramatically within border communities. The dissertation examines how the role of written law in the borderlands divides land and inhabitants and reconstructs a new understanding of the borderlands through oral histories and resistance by border communities. The overall goal of the dissertation is to challenge current scholarship to address the conceptual and sociopolitical task of a world in which legal representations and abstractions supersede the complex reality of community relations. As legal anthropologist Sally Falk Moore identified, we must consider carefully whether or not law controls the social context and what this means for our own definitions of community, what are the boundaries and borders of communities, and the seemingly limitedness of social interaction that becomes based on such legal definitions. The dissertation analyzes the defining disconnect of law from the social context that manifests itself amongst border communities along the U.S.-Mexico border. By exploring how law creates, sustains, molds, and connects the phenomenon of sovereignty, economy, and international borders, we can begin to understand how actions of border communities along the U.S.-Mexico border define the disconnect of law from the social context by redefining community itself.

Description
Females are highly vulnerable to the effects of methamphetamine, and understanding the mechanisms of this is critical to addressing methamphetamine use as a public health issue. Hormones may play a role in methamphetamine sensitivity; thus, the fluctuation of various endogenous peptides during the postpartum experience is of interest. This honors thesis project explored the relation between anxiety-like behavior, as measured by activity in an open field, and conditioned place preference to methamphetamine in female versus male rats. The behavior of postpartum as well as virgin female rats was compared to that of male rats. There was not a significant difference between males and females in conditioned place preference to methamphetamine, yet females showed higher locomotor activity in response to the drug as well as increased anxiety-like behavior in open field testing as compared to males. Further study is vital to comprehending the complex mechanisms of sex differences in methamphetamine addiction.

Description
Previous studies exploring variability in sentencing decisions have consistently found gender differences, such that women receive lighter sentences than men. In the proposed study, I present a new framework for understanding gender differences in sentencing preferences, including circumstances under which no gender differences should emerge. The Affordance Management Approach suggests that our minds are attuned to both group- and individual-level threats and opportunities that others afford us. I conceptualize the sentencing difference between men and women as driven by perceived affordances that assist or hinder an individual in achieving certain fundamental goals. When faced with sanctioning an offender in our community, the offender's sex, the victim's age, and environmental variables such as the ratio of men to women may influence our decision-making, because these factors have affordance implications. Thus, I hypothesized that individuals will express differences in the sentencing of offenders who commit assault, and that these differences vary by offender sex, victim age, and sex-ratio. The results indicate that, as predicted, female offenders received lighter sentencing than men when the offender committed an assault against a same-sex adult, but received equally punitive sentences as men when the assault was committed against a child. In general, results do not support a consistent effect of sex ratio as a factor when making sentencing decisions. Although results do not fully support the current study's specific hypotheses, there remains much to be gained from applying an affordance management perspective to understanding variability in sentencing between the sexes.

Description
Scientists, lawyers, and bioethicists have pondered the impact of scientifically deterministic evidence on a judge or jury when deciding the sentence of a criminal. Though the impact may be one that relieves the amount of personal guilt on the part of the criminal, this evidence may also be the very reason that a judge or jury punishes more strongly, suggesting that this type of evidence may be a double-edged sword. 118 participants were shown three films of fictional sentencing hearings. All three films introduced scientifically deterministic evidence, and participants were asked to recommend a prison sentence. Each hearing portrayed a different criminal with different neurological conditions, a different crime, and a different extent of argumentation during closing arguments about the scientifically deterministic evidence. Though the argumentation from the prosecution and the defense did not affect sentencing, the interaction of type of crime and neurological condition did.

Description
There is preclinical evidence that the detrimental cognitive effects of hormone loss can be ameliorated by estrogen therapy (Bimonte, Acosta, & Talboom, 2010), however, one of the primary concerns with current hormone therapies is that they are nonselective, leading to increased risk of breast and endometrial cancers as well as heart disease. Thus, in order to achieve a successful and clinically relevant long-term hormone therapy option, it is optimal to find an estrogen therapy regimen that is selective to its target tissue. Recently, phytoestrogens have been found to exert selective, beneficial effects on cognition and brain. For example, genistein and diadzein produce neuroprotective effects in cognitive brain regions (Zhao, Chen, & Diaz Brinton, 2002). The purpose of this study was threefold: 1) to examine the cognitive impact of phytoestrogens in young ovariectomized rats, 2) to replicate the dose effects found in the Luine study (Luine et al., 2006), while controlling for manufacturer differences, and 3) to assess if the rodent diet used in our laboratory has an estrogenic-like cognitive impact.The current findings suggest that, at least for object memory, diets containing varying amounts of phytoestrogens can alter cognition, with diets containing high amounts of phytoestrogens showing potential benefits to this type of memory.

Description
The demographics of Arizona are changing as Hispanics children are passing through their youth and into adulthood. Yet, even with this changing population Arizona has demonstrated an unwillingness to provide adequate educational opportunities for Hispanic school children. The state has perpetuated fear throughout the Hispanic community in an attempt to marginalize and stigmatize the race. Such attempts have extended to youth in schools creating an environment of fear. This fear limits the academic potential of young Hispanics who are wary of government officials and institutions. Arizona has also failed to provide appropriate funding for programs used predominantly by Hispanic students leaving them unprepared for a workplace that desperately needs them. Finally, Arizona has refused to allow course content with a record of increasing academic achievement and graduation rates amongst Hispanics to be taught in schools. Taken as a whole Arizona's efforts are creating a cadre of unskilled and unprepared laborers who will be desperately needed to take jobs in the Arizona economy in the coming years. This blatant disregard for the educational needs of a large segment of the population will have a devastating impact on Arizona's future.

Description
Substance abuse disorders affect 15.3 million people worldwide. The field has primarily focused on dopaminergic drugs as treatments for substance use disorders. However, recent work has demonstrated the potential of serotonergic compounds to treat substance abuse. Specifically, the serotonin 1B receptor (5-HT1BR), a Gi-coupled receptor located throughout the mesocorticolimbic dopamine system, has been implicated in the incentive motivational and rewarding effects of cocaine. Our research suggests that the stimulation of 5-HT1BRs produces different effects at various time points in the addiction cycle. During maintenance of chronic cocaine administration, 5-HT1BR stimulation has a facilitative effect on the reinforcing properties of cocaine. However 5-HT1BR stimulation exhibits inhibitory effects on reinforcement during prolonged abstinence from cocaine. The aim of this study was to examine the possibility of a switch in the functional role of 5-HT1BRs in the locomotor effects of cocaine at different time points of chronic cocaine administration in mice. We found that the 5-HT1BR agonist CP 94,253 increased locomotor activity in mice tested one day after the last chronic cocaine administration session regardless of whether the chronic treatment was cocaine or saline and regardless of challenge injection (i.e., cocaine or saline). Yet after abstinence, CP 94,253 induced a decrease in locomotor activity in mice challenged with saline and attenuated cocaine-induced locomotion relative to cocaine challenge after vehicle pretreatment. These findings suggest that a switch in the functional role of 5-HT1BR is observed at different stages of the addiction cycle and further suggest that clinical applications of drugs acting on 5-HT1BR should consider these effects.

Description
Animal models have led to important discoveries in biomedical research; their utility to psychiatry and comparative neuroscience is less clear. Disorders of higher-order brain function, schizophrenia chief among them, have proven exceptionally elusive to model. Schizophrenia researchers are of two minds about the possibility of modeling the schizophrenia phenotype(s) in laboratory animals: at one and the same time they are both pessimistic and pragmatic. That is, they admit the discouraging difficulty of the task, and yet proceed, apparently undeterred, with putative animal models of schizophrenia, as if the criticisms that yield the pessimistic judgments simply do not matter. In this article, we survey the criticisms and evaluate their merits. We then ask: what would it mean to take seriously the claim that modeling schizophrenia in at least some non-human animals - namely, rodents - is doomed, futile, impossible? How would, and how should, schizophrenia research be undertaken were the current animal models rejected as simply inadequate to the task? Our aim is not to disparage sound research into the etiology, symptomatology, and treatment of schizophrenia, but rather to emphasize the scope of the gap between current and optimal research practices. We conclude with recommendations to reinvigorate the quest to understand, prevent, and treat schizophrenia.
