Description
This was a social movements analysis of the protests against Arizona's Senate Bill 1070, better known as the "Show Me your Papers" law. The project looked at the role religious organizations and religious leaders took in the protests as part of the immigration rights movement in Arizona. It was found that there were frames, networks, and resources already in place when SB 1070 passed in 2010. Rather than a movement emerging as a response to the legislation, it looked more like a social movement in crisis. The established frames, networks, and resources allowed this social movement to meet the challenge and have some measure of success in resisting and overturning SB 1070.

Description
Methane (CH4) is very important in the environment as it is a greenhouse gas and important for the degradation of organic matter. During the last 200 years the atmospheric concentration of CH4 has tripled. Methanogens are methane-producing microbes from the Archaea domain that complete the final step in breaking down organic matter to generate methane through a process called methanogenesis. They contribute to about 74% of the CH4 present on the Earth's atmosphere, producing 1 billion tons of methane annually. The purpose of this work is to generate a preliminary metabolic reconstruction model of two methanogens: Methanoregula boonei 6A8 and Methanosphaerula palustris E1-9c. M. boonei and M. palustris are part of the Methanomicrobiales order and perform hydrogenotrophic methanogenesis, which means that they reduce CO2 to CH4 by using H2 as their major electron donor. Metabolic models are frameworks for understanding a cell as a system and they provide the means to assess the changes in gene regulation in response in various environmental and physiological constraints. The Pathway-Tools software v16 was used to generate these draft models. The models were manually curated using literature searches, the KEGG database and homology methods with the Methanosarcina acetivorans strain, the closest methanogen strain with a nearly complete metabolic reconstruction. These preliminary models attempt to complete the pathways required for amino acid biosynthesis, methanogenesis, and major cofactors related to methanogenesis. The M. boonei reconstruction currently includes 99 pathways and has 82% of its reactions completed, while the M. palustris reconstruction includes 102 pathways and has 89% of its reactions completed.

Description
Mass media has played a central role in the construction of "illegal" immigration as a crisis, despite demographic trends suggesting otherwise, resulting in public concern and extreme policies. Additional coverage by local news has brought the issue closer to home, leading state legislatures to action. This project analyzes trends in a 10 year period in local news articles and state-level legislation about undocumented immigration in Arizona and Alabama. The representation of immigration as a threat has consequences for the lives of immigrants and what it means to be an American.

Description
This study focused on the connection between the EnvZ/OmpR two-component regulatory system and the iron homeostasis system in Escherichia coli, specifically how a mutant form of EnvZ11/OmpR is able to reduce the expression of fepA::lacZ, a reporter gene fusion in E. coli. FepA is one of several outer membrane siderophore receptors that allow extracellular siderophores bound to iron to enter the cells to power various biological processes. Previous studies have shown that in E. coli cells that expressed a mutant allele of envZ, called envZ11, which led to altered expression of various iron genes including down regulation of fepA::lacZ. The wild type EnvZ/OmpR system is not considered to regulate iron genes, but because these envz11 strains had downregulated fepA::lacZ, this study was undertaken to understand the connection and mechanisms of this downregulation. A large number of Lac+ revertants were obtained from the B32-2483 strain (envz11 and fepA::lacZ) and 7 Lac+ revertants that had reversion mutations not directly correcting the envZ11 allele were further characterized. With P1 phage transduction genetic mapping that involved moving a kanamycin resistance marker linked to fepA::lacZ, two Lac+ revertants were found to have their reversion mutations in the fepA promoter region, while the other five revertants had their mutations mapping outside the fepA region. These two revertants underwent DNA sequencing and found to carry two different single base pair mutations in two different locations of the fepA promoter region. Each one is in the Fur repressor binding region, but one also may have affected the Shine-Dalgarno region involved in translation initiation. All 7 reveratants underwent beta-galactosidase assays to measure fepA::lacZ expression. The two revertants that had mutations in the fepA promoter region had significantly increased fepA activity, with the revertant with the Shine-Dalgarno mutation having the most elevated fepA expression. The other 5 revertants that did not map in the fepA region had fepA expression elevated to the same level as that found in the wild type EnvZ/OmpR background. The data suggest that the negative effect of envZ11 can be overcome by multiple mechanisms, including directly correcting the envZ11 allele or changing the fepA promoter region.

Description
Since the 1990s, the United States has been increasingly hosting large numbers of foreign students in its higher education sector and continues to accommodate these skilled college graduates in its job market. When international students graduate, they can transition from an international student to a skilled migrant. Yet their decision-making process to stay in the receiving country (the United States), to return to sending countries, or to move on to another country, at different stages of such transition period, is not presently understood. This dissertation examines the experiences of these “migrants in transition period” when they face the “to return or to stay” choices under structural and institutional forces from the sending and receiving countries. This research adopts the conceptual framework of human capital, social capital, and cultural capital, to investigate how social capital and cultural capital impact the economic outcomes of migrants’ human capital under different societal contexts, and how migrants in the transition period cope with such situations and develop their stay or return plans accordingly. It further analyzes their decision-making process for return during this transition period. The empirical study of this dissertation investigates contemporary Chinese student migrants and skilled migrants from People’s Republic of China to the United States, as well as Chinese returnees who returned to China after graduation with a US educational degree. Findings reveal the impact of social and cultural capitals in shaping career experiences of skilled Chinese migrants, and also explore their mobility and the decision-makings of such movement of talent.

Description
This dissertation focuses on the incorporation of twenty first century mixed-status families, living in Phoenix, Arizona and Central Mexico. Using a combination of research methods, chapters illustrate patterns of immigrant incorporation by focusing on well-being, community reception, and national identity. First, results of mixed-method data collected in Phoenix, Arizona from 2009-2010 suggest that life satisfaction varies by integration scores, a holistic measure of how immigrants are integrating into their communities by accounting for individual, household, and contextual factors. Second, findings from qualitative data collected in Mexico during 2010, illustrate that communities receive parents and children differently. Third, a continued analysis of qualitative 2010 data from Mexico, exhibits that both parents and children identify more with the U.S. than with Mexico, regardless of where they were born. Together these chapters contribute to broad concepts of assimilation, well-being, community reception, and national identity.

Description
The purpose of this research was to understand the migration process as experienced by unaccompanied immigrant minors (UIMs). That is, to form a better understanding of why they seek migration, what motivates their migration, what happens to them on their migration journey, and how they adapt to their new communities in the United States. Using qualitative research methods, 60 semi-structured in-depth interviews were collected, along with 12 ethnographic interviews, and participant observations. The immigrants’ narratives were rich with data, and capture the plight that UIMs undertake as they leave their home countries. This study analyzes the dynamic of age in all facets of the migration process, by taking into account that children are participants of the migration process just as much as adults.
The dissertation generated several findings; the first was to provide a profile of an Unaccompanied Minor, and for the sake of the study, only participants from Mexico, El Salvador, Honduras and Guatemala were interviewed. From those interviewed, we learned that UIMs are a heterogeneous group. They come from diverse backgrounds in terms of household structures; (nuclear family structures, single-parent structures, extended-family structures, and migrant-family structures). Also, education levels varied; (some finished elementary or even secondary school, but for those living in rural areas it was harder to attend school due to the distance and availability of educational facilities). Many also worked in the labor force from an early age. One salient theme that UIMs talked about in relation to their home life was how the increase in violence in many Latin American countries was threatening their safety, especially for UIMs from El Salvador and Honduras. The next major finding was the ability to see the multiple stages UIMs experience, including: initiation/decisions to migrate, journey, arrival/adaptation and what takes place in each of these stages.

Description
This qualitative study examines how fathers, who stay home with their children and identify as the main care-giver within their family, construct their role as the primary caregiver. I analyze the narratives of stay-at-home fathers focusing on the thematic areas of isolation, resistance and the division of household labor. Unlike previous research, I examine the ways in which fathers construct their position as a stay-at-home father separate from the traditional stay-at-home mother role. Consequently, I focus on the constructions of masculinities by stay-at-home fathers that allows for the construction of the stay-at-home role to be uniquely tied to fatherhood rather than motherhood.
In this research, I explore three questions: 1) how do stay-at-home fathers construct their masculinity, specifically in relation to their social roles as fathers, partners, peers, etc.? 2) Is the negotiation of household labor, including care work and household tasks, in these families a reflection of shifting gender roles in the home where the primary caregiver is the father? 3) In what ways does social location and intersecting identities influence the ways in which fathers construct this stay-at-home identity?
My research emphasizes how these fathers understand their role as a stay-at-home father while challenging some traditionally dominant expectations of fatherhood. Specifically, I use themes of isolation, resistance, and the division of household labor in order to understand the multiple ways fathers experience their roles as stay-at-home parents.

Description
In the midst of historical ruptures and transfiguration caused by a globalization that has restructured new realities marked by violence, Central American and Chicanos realities have come into contact in a global space such the United States. Thus, the interdependence between these two cultures is so close that the literary influences are unavoidable. We argue that there is an asymmetrical relationship in the narrative of globalization, which sets new unpublished orders and generates perceptions of reality. The ideological dimensions of globalization that have caused systemic violence can be traced through military interventions and economic ventures. Thus, the subject of our research is assumed as a literary whole within certain social facts, i.e., as a symbolic aspect of the processes of violence within a culture undermined by globalization. Hence, in using theory of violence by Slavoj Ziek and theory of globalization by Manuel Castells, Tony Shirato, Jenn Webb, James Petra, and Henry Veltmeyer, we explore the narrative and criticism of U.S-Central Americans and Chicano in order to expose the forces of systemic violence that globalization produces. Our results show that, historically, globalization has formulated epistemologies via violence for Chicanos and U.S-Central Americans; such violence marks both groups, allowing for solidarity, through discursive practices of resistance, to take place in the textual space as well as in the real world. Such solidarity disrupts the textual borders, creating a dialogue of mutual understanding.
