Description
This project addresses the high demand of housing units in the Gila River Indian Community and proposes an architectural intervention with the intent of bringing tribal culture into the everyday context of the home. Initially, the existing condition is critiqued from an architectural and cultural lens, and establishes the current realities of the residents. An investigation of the existing condition and the surrounding context determined that the immediate contradiction to the existing house is the storytelling tradition of the Akimel O'odham and Pee Posh tribes. This project accepts and revises the existing condition and attempts to combine it with the fundamental traits of storytelling culture to create a house that encourages storytelling across generations, and serves as a space that allows residents to practice culture in the every day.

Description
The Mexican gray wolf (Canis lupus baileyi) is a genetically distinct subspecies of the gray wolf (Canis lupus) that was driven to the brink of extinction as a result of human persecution. The wolf is listed as Endangered under the Endangered Species Act, and a recovery program is underway in Arizona and New Mexico to restore its population. However, the wolf is struggling to recover due to high mortality, which is a result of continued human hostility toward it. This thesis examines historical and current human attitudes toward the wolf and the implications that they have had on the extermination and recovery of the subspecies. An overview is given of wolf biology, the history of wolf extermination and recovery, and recent events relating to the recovery of the wolf. Negative impacts on ranching, hunting, and human safety are the main reasons for opposition toward wolves and wolf recovery; these concerns are analyzed, and solutions to them are proposed, with the goal of addressing them while fostering non-lethal coexistence with the wolf. In addition, opposition to wolves and wolf recovery is tied in with larger socio-political issues and is influenced by the representation of the wolf in culture; these issues in the context of wolves are also analyzed.

Description
In developed countries, municipalities deliver drinking water to constituents through water distribution systems. These transport water from a treatment plant to homes, restaurants, and any other site of end use. Proper water distribution system infrastructure functionality is a critical concern to city planners and managers because component failures within these systems restrict or prevent the ability to deliver water. The reduced capacity to deliver water forces the health and well being of all citizens into jeopardy. The breakdown of a component can even spark the failure of several more components, causing a sequence of cascading failures with catastrophic consequences. To make matters worse, some forms of component failures are unpredictable and it is impossible to foresee every possible failure that could occur. In order to prevent cataclysmic losses that are experienced during system failures, the development of resilient water distribution infrastructure is vital. A resilient water distribution system possesses an adaptive capacity to mitigate the loss of service resulting from component failures. Traditionally, infrastructure resilience research has been retrospective in nature, analyzing the infrastructure system after it suffered a failure event. However, this research project takes water distribution resilience research in a new direction. The research identifies the Sensing Anticipating, Adaptation, and Learning processes that are inherent in the current operations of each component in the water distribution system (pumps, pipes, valves, tanks, nodes). Additional SAAL processes have been recommended for the components that lack adaptive management in current practice. This workis unique in that it applies resilience theory to water distribution systems in an anticipatory manner. This anticipatory application of resilience will provide operators with actionable process for them to implement during failure situations. In this setting, resilience is applied to existing systems for noticeable improvements in operation during failure situations.

Description
The Colorado River is the lifeblood for seven Basin States including Colorado, Utah, Wyoming, New Mexico, Arizona, California and Nevada. This water source aided westward expansion and allowed the arid Southwest to grow. Today, the river is over-allocated resulting in reduced flows. This could lead to water challenges in Arizona and the other Basin states. This river is the single largest entity from which Arizona receives water. Despite this, Arizona is still better situated for water cutbacks than other states like California. Arizona has more than nine million acre-feet of banked underground water and access to other water sources including the Salt and Verde rivers. Government officials are making decisions now that will affect water usage in Arizona for decades and generations to come. Digital media, such as iPad magazines are a good way to reach this technologically savvy generation and engage them concerning important issues. Designing for digital platforms presents unique opportunities. This platform requires solid content and visually appealing design to attract a Millennial audience born between the years 1981 and 1996, according to Pew Research Center. Digital magazines currently present a small segment of the media market, however this segment is growing exponentially. A study by Pew Research Center reports that this slice of the population is interested in consuming the news and emerging technologies such as digital magazines. These are good ways to reach and interest a digitally engaged readership. Reaching this age group is important because the Millennial generation will need to determine the future of the Colorado River and water use in Arizona. To ensure the future of water in the West, this generation needs to "learn about the reality of our water supply, what our real water challenges are and then get engaged and have a voice in what we do about our water planning for the future" (Porter, 2015). DISCLAIMER: The digital magazine was created in InDesign with interactive PDFs, which are best viewed on tablets. Screenshots of the magazine are included to demonstrate the magazine.

Description
The purpose of this honors project is to analyze the difference between different powder separation techniques, and their suitability for my capstone project – ‘Effect of Powder Reuse on DMLS (Direct Metal Laser Sintering) Product Integrity’. Due to the nature of my capstone project, my group needs to characterize foreign contaminants in IN 718 (Ni-based superalloy) powder with a mean diameter around 40um. In order to clearly analyze the contaminants and recycle useful IN 718 powders, powder separation is favorable since the filtered samples will be much easier to characterize rather than inspect all the powders at once under microscope. By conducting literature review, I found that powder separation is commonly used in Geology, and Chemistry department. To screen which combination of techniques could be the best for my project, I have consulted several research specialists, obtained adequate knowledge about powder separation. Accordingly, I will summarize the pros and cons of each method with regard the specific project that I am working on, and further explore the impacts of each method under economical, societal, and environmental considerations. Several powder separation techniques will be discussed in details in the following sections, including water elutriation, settling column, magnetic separation and centrifugation. In addition to these methods, sieving, water tabling and panning will be briefly introduced. After detailed comparison, I found that water elutriation is the most efficient way to purity IN718 powder for reuse purpose, and recovery rate is as high as 70%, which could result in a significant reduction in the manufacturing cost for Honeywell since currently Honeywell only use virgin powders to build parts, and 90% of the leftover powders are discarded.

Description
In Arizona's early history, Females garnered more independence than most other women in the United States because they were forced to build a completely new life in settlements with little to no infrastructure. Now, Arizona has achieved a level of equality that no other state has yet to achieve in regard to gender representation. Yet, we have yet to achieve total equity. This paper looks to analyze responses that female senators from the Arizona State Legislature gave while being interviewed by the author. With questions derived from previous research conducted on women in politics at the state and federal level, this paper will delve into the personal experiences of six female senators. Although their personal narratives differ, their stories seem to reflect a collective tie that unites the female members together, beyond party allegiance. Each of the responses given by the senators had some aspects that showed trends supporting the majority of the hypotheses. Moving forward, in order to achieve 50% equality, two more senators would need to be elected and replace male senators.

Description
The free-base tetra-tolyl-porphyrin and the corresponding cobalt and iron porphyrin complexes were synthesized and characterized to show that this class of compound can be promising, tunable catalysts for carbon dioxide reduction. During cyclic voltammetry experiments, the iron porphyrin showed an on-set of ‘catalytic current’ at an earlier potential than the cobalt porphyrin’s in organic solutions gassed with carbon dioxide. The cobalt porphyrin yielded larger catalytic currents, but at the same potential as the electrode. This difference, along with the significant changes in the porphyrin’s electronic, optical and redox properties, showed that its capabilities for carbon dioxide reduction can be controlled by metal ions, allotting it unique opportunities for applications in solar fuels catalysis and photochemical reactions.

Description
This thesis examines the problems that occur when the politics and practices of social services, specifically maternal and prenatal care, are guided by a distorted understanding of immigration. It compares the politics and practice of this care across two international borders: the U.S.-Mexico and that within Hispaniola. In an ideal world, care would be extended to all individuals regardless of citizenship. However, since every welfare state has its limits at the national border, citizenship matters to both federal governments and medical professionals. Government-provided resources play an integral role in the current immigration debate, as these programs are a collective investment in which all individuals contribute in order to sustain it. The United States developed the welfare state in order to provide necessary resources to those who could not afford it. Its creators did not view these services as a handout, rather as a support for the future workforce of the country. However, health care was and still is not provided on this model of economic and social citizenship. Current U.S. healthcare policy dictates that no one can be turned away in an emergency situation because someone cannot pay their medical bill, including undocumented immigrants. But for immigrant mothers carrying children across the border, maternal and prenatal care does not qualify as an emergency and the federal government aid typically does not extend to them them as citizens. When care is extended to undocumented immigrants in the United States at all, it typically is provided to the child through Medicaid, who is by dint of the Fourteenth Amendment considered a citizen after birth. The relation between the Dominican Republic and Haiti offers a more complex situation, as the idea of birthright citizenship has recently been revoked. Following the Haitian Earthquake in 2010, the only healthcare to which many Haitians had access was across the Hispaniola border. Haitian women who give birth to children in the Dominican Republic are often not evaluated by a doctor until they are entering the delivery process, and even then health-care is complicated by or denied because of racial prejudice and unclear legal situation. In September of 2013, the Constitutional Court of the Dominican Republic issues a new ruling which declared that any immigrant born between 1929 and 2010 without documentation of their own or of their ancestors does not have citizenship, rendering many Haitians born in the Dominican Republic essentially stateless. To be born to a non-citizen mother typically means the child will likely be born with little or no prenatal care, and the mother will receive poor or inadequate care. Prenatal care is one of the most inexpensive elements of a care-model that carries huge returns relative to its costs. All governments would benefit from improved access to maternal and prenatal care because its future citizens who receive such care would be born healthier and have fewer expensive chronic illnesses. Fewer chronic illness among a population would have huge returns on the welfare state because fewer people would be utilizing it for expensive medical treatments. Though most medical professionals condemn the extreme act of denying care to pregnant women or infants (documented or not), the Dominican Republic and the United States have a popular politics that embraces this cruelty, despite the fact that both pride themselves on a multi-ethnic population. It is easy for policymakers to incriminate undocumented immigrants and claim that they are responsible for an illegitimate share of the consumption of the country's resources. Therefore, it seems likely that the host country's perceptions of immigrant natality and maternity help construct a negative image of the immigration "problem" in such a way that laws and policies are designed without accurate rationale. This thesis examines how the United States and the Dominican Republic might improve the relationship between the culture of healthcare and the role of the legal system for immigrants and their children. It seeks to understand the reasons, motivations, and consequences for denying immigrants services on the account of their citizenship status. The social, economic, and health consequences of being an undocumented citizen will be examined. Current legal policy and what political roadblocks and cultural prejudices must be overcome in order to implement a successful policy will be reviewed. Finally, the best practices prenatal care as a national investment will be discussed, as will the problem of cross-cultural perception of natality, maternity, and immigration.

Description
This is a creative thesis project on the topic of the third party logistics industry, and the improvements that are possible through the implementation of goods to person technologies. The scope of the project entails the relationship between Company X, which is a third party logistics provider, and Company Y, a major toy retailer. This thesis identifies current trends for the third party logistics industry such as rising operating costs and average savings achieved through these business relationships. After identifying the negative trends that Company X is vulnerable to such as high human resources costs, and cost of quality issues. Given the findings derived from industry data, a final recommendation was settled on to improve productivity and ultimately reduce the use of temporary labor for Company X. The implementation of a goods to person technology solution provides the opportunity to reduce hours of operation, man hours, as well as direct and indirect costs such as labor. Research has proven that firms operating in the retail industry rely heavily on temporary labor to handle the seasonal demand brought by the holidays, thus this recommendation could be applied to a variety of operations. The data compiled throughout this thesis have major implications for the third party logistics industry and achieving long term profitability in operations management.

Description
This work challenges the conventional perceptions surrounding the utility and use of the CMS Open Payments data. I suggest unconsidered methodologies for extracting meaningful information from these data following an exploratory analysis of the 2014 research dataset that, in turn, enhance its value as a public good. This dataset is favored for analysis over the general payments dataset as it is believed that generating transparency in the pharmaceutical and medical device R&D process would be of the greatest benefit to public health. The research dataset has been largely ignored by analysts and this may be one of the few works that have accomplished a comprehensive exploratory analysis of these data. If we are to extract valuable information from this dataset, we must alter both our approach as well as focus our attention towards re-conceptualizing the questions that we ask. Adopting the theoretical framework of complex systems serves as the foundation for our interpretation of the research dataset. This framework, in conjunction with a methodological toolkit for network analysis, may set a precedent for the development of alternative perspectives that allow for novel interpretations of the information that big data attempts to convey. By thus proposing a novel perspective in interpreting the information that this dataset contains, it is possible to gain insight into the emergent dynamics of the collaborative relationships that are established during the pharmaceutical and medical device R&D process.
