Description
In 2016, in the United States alone, the cosmetics industry made an estimated 62.46 billion dollars in revenue (Revenue of the Cosmetic Industry in the U.S. 2002-2016 | Forecast). With a consistent increase in sales in the last several years, the industry has reached continued success even during times of hardship, such as the Great Recession of 2008. The use of Corporate Social Responsibility (CSR), external campaigns, and thoughtful packaging and ingredients resonates with targeted consumers. This has served as an effective strategy to maintain growth in the industry. Cosmetic companies promote their brand image using these sustainability tactics, but there seems to be a lack of transparency in this unregulated industry. The purpose of this thesis is to determine if the cosmetics industry is a good steward of the sustainability movement. Important terms and concepts relating to the industry will be discussed, then an analysis of sustainability focused cosmetic brands will be provided, which highlights the extent to which these brands engage in activities that promote sustainability. This is followed by an application of findings to a company that could benefit from using such practices. Overall, the analysis of the different brands proved to be shocking and disappointing. This is due to the sheer amount that scored very poorly based on the sustainability criteria developed. The cosmetics industry is too inconsistent and too unregulated to truly act as a good steward for sustainability. Though some companies in the industry succeed, these accomplishments are not consistent across all cosmetic companies. Hence, the cosmetics industry as a good steward for sustainability can only be as strong as its weakest link.

Description
Magnetic resonance imaging (MRI) data of metastatic brain cancer patients at the Barrow Neurological Institute sparked interest in the radiology department due to the possibility that tumor size distributions might mimic a power law or an exponential distribution. In order to consider the question regarding the growth trends of metastatic brain tumors, this thesis analyzes the volume measurements of the tumor sizes from the BNI data and attempts to explain such size distributions through mathematical models. More specifically, a basic stochastic cellular automaton model is used and has three-dimensional results that show similar size distributions of those of the BNI data. Results of the models are investigated using the likelihood ratio test suggesting that, when the tumor volumes are measured based on assuming tumor sphericity, the tumor size distributions significantly mimic the power law over an exponential distribution.

Description
From 2007 to 2017, the state of California experienced two major droughts that required significant governmental action to decrease urban water demand. The purpose of this project is to isolate and explore the effects of these policy changes on water use during and after these droughts, and to see how these policies interact with hydroclimatic variability. As explanatory variables in multiple linear regression (MLR) models, water use policies were found to be significant at both the zip code and city levels. Policies that specifically target behavioral changes were significant mathematical drivers of water use in city-level models. Policy data was aggregated into a timeline and coded based on categories including user type, whether the policy was voluntary or mandatory, the targeted water use type, and whether the change in question concerns active or passive conservation. The analyzed policies include but are not limited to state drought declarations, regulatory municipal ordinances, and incentive programs for household appliances. Spatial averages of available hydroclimatic data have been computed and validated using inverse distance weighting methods. The data was aggregated at the zip code level to be comparable to the available water use data for use in MLR models. Factors already known to affect water use, such as temperature, precipitation, income, and water stress, were brought into the MLR models as explanatory variables. After controlling for these factors, the timeline policies were brought into the model as coded variables to test their effect on water demand during the years 2000-2017. Clearly identifying which policy traits are effective will inform future policymaking in cities aiming to conserve water. The findings suggest that drought-related policies impact per capita urban water use. The results of the city level MLR models indicate that implementation of mandatory policies that target water use behaviors effectively reduce water use. Temperature, income, unemployment, and the WaSSI were also observed to be mathematical drivers of water use. Interaction effects between policies and the WaSSI were statistically significant at both model scales.

Description
The purpose of this project is to create an affordable and low-environmental impact housing model for high-density urban living. Detailed research was completed to select the Arizonan city of Tempe for the basis of this model such as author's preference and alarming demographic and economic factors. The finalized model will consist of shipping containers that will be converted into housing. These domiciles are ideal for a maximum of 1-2 occupants. The units will be stacked into communities to accomplish high density. These shipping containers will be used rather than brand new, the community landscape will consist of natural desert landscaping, a recycling program will be offered, and solar panels will be used to power the units. The decision for these features fulfills both the mission of the project and markets to the main demographic group of residents in Tempe, Millennials, who usually place sustainability in high regard. These units are meant to be purchased by the target market and other citizens to increase homeownership rates in Tempe. Their ownership rights will be analogous owning a condo, where they will own the converted shipping container itself, but not the property the unit is placed on. In addition, these units qualify for traditional loans and will appreciate similar to normal housing options. After conceptualizing the idea, various costs were analyzed for construction of the units. A critical component of the project is to receive government grants to fund the venture in order to continue the mission and keep prices of these units low. This model is expandable and could be moved to other cities within the state or potentially other states through future government grant attainment and success with the first installation. These communities will be managed by a company, Shipping Designs, which will be a limited liability company created by the author, Shauna Burgoyne.

Description
Cancer poses a significant burden on the global health system and represents a leading cause of death worldwide. For late-stage cancers, the traditional treatments of chemotherapy, radiation, and surgery are not always viable, and they can pose unnecessary health risks to the patients. New immunotherapies, such as adoptive cell transfer, are being developed and refined to treat such cancers. T cell immunotherapies in particular, where a patient’s T cell lymphocytes are isolated and amplified to be re-infused into the patient or where human cell lines are engineered to express T cell receptors for the recognition of common cancer antigens, are being expanded on because for some cancers, they could be the only option. Constructing an optimal pipeline for cloning and expression of antigen-specific TCRs has significant bearing on the efficacy of engineered cell lines for ACT. Adoptive T cell transfer, while making great strides, has to overcome a diverse T cell repertoire – cloning and expressing antigen-specific TCRs can mediate this understanding. Having identified the high frequency FluM1-specific TCR sequences in stimulated donor PBMCs, it was hypothesized that the antigen-specific TCR could be reconstructed via Gateway cloning methods and tested for expression and functionality. Establishing this pipeline would confirm an ability to properly pair and express the heterodimeric chains. In the context of downstream applications, neoantigens would be used to stimulate T cells, the α and β chains would be paired via single-cell or bulk methods, and instead of Gateway cloning, the CDR3 hypervariable regions α and β chains alone would be co-expressed using Golden Gate assembly methods.

Fashion is individual in its expression. It is also universal. Fashion is a cumulation of different influences and different interpretations. We currently live in a climate divided by race, culture, gender, and so much more. It is so difficult to find common ground on a global platform. Something that stands alone is fashion. Fashion is influenced by so many aspects. Of these, aspects that I am interested in are culture and sustainability. When combined with culture, fashion can anchor and have a root to the generations that came before us. When combined with sustainability, we have an anchor to the planet that we share with everyone. The result of fashion is always the same, beautiful art. I want people to see the beauty not only in the art itself, but the differences and similarities that such art provides. We all come from the same world but have different ways of expressing that world. My goal is to show people that they need to acknowledge the differences but can choose to see the similarities of each culture. Additionally, I redesign garments that capture an emotion and a story. Making each piece individual yet serving a greater purpose sustainability wise. I envision the principle of sustainable fashion to be the basis of each piece of clothing. Therefore, for my creative project I am constructing five art pieces representing five cultures that has had a significant influence on my life and personal style. These cultures are those of UAE, Germany, Nepal, Mexico, and Spain. Each of these garments are made from recycled fabric and clothing donated by family and friends. My objective is to display sustainable fashion that has deep cultural influence. Every piece has a story and an emotion attached as well to create a connection with the clothing itself.

Description
Cancer is a disease that occurs in many and perhaps all multicellular organisms. Current research is looking at how different life history characteristics among species could influence cancer rates. Because somatic maintenance is an important component of a species' life history, we hypothesize the same ecological forces shaping the life history of a species should also determine its cancer susceptibility. By looking at varying life histories, potential evolutionary trends could be used to explain differing cancer rates. Life history theory could be an important framework for understanding cancer vulnerabilities with different trade-offs between life history traits and cancer defenses. Birds have diverse life history strategies that could explain differences in cancer suppression. Peto's paradox is the observation that cancer rates do not typically increase with body size and longevity despite an increased number of cell divisions over the animal's lifetime that ought to be carcinogenic. Here we show how Peto’s paradox is negatively correlated for cancer within the clade, Aves. That is, larger, long-lived birds get more cancer than smaller, short-lived birds (p=0.0001; r2= 0.024). Sexual dimorphism in both plumage color and size differ among Aves species. We hypothesized that this could lead to a difference in cancer rates due to the amount of time and energy sexual dimorphism takes away from somatic maintenance. We tested for an association between a variety of life history traits and cancer, including reproductive potential, growth rate, incubation, mating systems, and sexual dimorphism in both color and size. We found male birds get less cancer than female birds (9.8% vs. 11.1%, p=0.0058).

Description
The purpose of this thesis is to study the issue of animal agriculture and why people chose to consume sentient beings such as pigs, chickens, and cows yet house equally as sentient and intelligent beings such as dogs and cats. I want to understand people’s reasoning and logic behind discriminating who they love versus who they eat. This thesis intends to help readers become more aware of the cognitive dissonance behind the food choices that most Americans make up to three times a day. Data was collected through Google Form surveys for freshman living in the dorms at Barrett, The Honors College. The results showed that animal intelligence did not factor in people’s decision to consume their parts. Additionally, this study concluded that participants are more likely to feel less guilty when they are under the false belief that the meat they purchased was mislabeled with terms such as ‘humane slaughter.’

Description
The idea of a packed promenade, crowded with busy shoppers and completely empty of cars may seem like a holdover from rustic 19th century Europe — but many present day examples can be found right here in the United States — in college towns like Madison, WI, big cities like Denver CO, and lots of places in between. In recent years, proposals to change Mill Ave. here in Tempe have been introduced to modify University Dr. to Rio Salado Pkwy. into just that type of pedestrianized shopping mall, closing it to all automobile traffic outside of emergency vehicles.
As two students who frequent the potentially affected area, we explore the feasibility of such a proposal to continue to grow the downtown Tempe economy. Our research focuses upon several different areas — exploring positive and negative cases of street pedestrianization (whether in Europe, the United States, or other countries), the impact a permanent street closure in Tempe would have both on personal traffic and on the city’s robust public transit system, potential security concerns, opinions of the business community on the proposed change, and the political feasibility of passing the proposal through the Tempe City Council.

Description
Although the Leadership Scholarship Program has seen successful recruiting processes throughout changes in leadership of the program; the organization expressed a need for major overhaul to reevaluate the decisions of the process and to establish backing for those decisions. By asking current and alumni members of the program about what they would like to see in a future member of the program as well as which parts of the process they found most important, the qualities of a future member of the program could be established and weighted. The goals of the reevaluation were to help eliminate bias, discrepancies between applications with extremely different uncontrollable factors, define points of discrepancies, and establish organizational sustainability while achieving a 100% acceptance rate from offered students. Each of these goals was achieved through methods outlined in the LSP Selection Process Manual that was written as a result of this reevaluation. The manual also outlines ways to improve the process going forward.
