Description
Cancer rates vary between people, between cultures, and between tissue types, driven by clinically relevant distinctions in the risk factors that lead to different cancer types. Despite the importance of cancer location in human health, little is known about tissue-specific cancers in non-human animals. We can gain significant insight into how evolutionary history has shaped mechanisms of cancer suppression by examining how life history traits impact cancer susceptibility across species. Here, we perform multi-level analysis to test how species-level life history strategies are associated with differences in neoplasia prevalence, and apply this to mammary neoplasia within mammals. We propose that the same patterns of cancer prevalence that have been reported across species will be maintained at the tissue-specific level. We used a combination of factor analysis and phylogenetic regression on 13 life history traits across 90 mammalian species to determine the correlation between a life history trait and how it relates to mammary neoplasia prevalence. The factor analysis presented ways to calculate quantifiable underlying factors that contribute to covariance of entangled life history variables. A greater risk of mammary neoplasia was found to be correlated most significantly with shorter gestation length. With this analysis, a framework is provided for how different life history modalities can influence cancer vulnerability. Additionally, statistical methods developed for this project present a framework for future comparative oncology studies and have the potential for many diverse applications.

Description
Despite the 40-year war on cancer, very limited progress has been made in developing a cure for the disease. This failure has prompted the reevaluation of the causes and development of cancer. One resulting model, coined the atavistic model of cancer, posits that cancer is a default phenotype of the cells of multicellular organisms which arises when the cell is subjected to an unusual amount of stress. Since this default phenotype is similar across cell types and even organisms, it seems it must be an evolutionarily ancestral phenotype. We take a phylostratigraphical approach, but systematically add species divergence time data to estimate gene ages numerically and use these ages to investigate the ages of genes involved in cancer. We find that ancient disease-recessive cancer genes are significantly enriched for DNA repair and SOS activity, which seems to imply that a core component of cancer development is not the regulation of growth, but the regulation of mutation. Verification of this finding could drastically improve cancer treatment and prevention.

Description
I will be investigating the merit of participatory culture in online literary roleplaying. While looking at an affinity space within participatory culture, I will be examining the importance of narrative within a roleplay board, the value placed in writing ability and habitual participation, and the gaining of social capital within the affinity space of players through the scope of two forms of participatory culture: expressions and collaborative problem solving. I will also look at the limitations of literary roleplaying before talking about the potential of roleplaying to be used as a tool for students in the classroom. Throughout my investigation, I pool information from online roleplay forum boards as well as Tumblr blogs. Drawing from these examples, I hope to not only show the value and merit of online roleplaying as a form of literature, but also demonstrate its potential as a curriculum guide for educators.

Description
Glioblastoma Multiforme (GBM) is an aggressive and deadly form of brain cancer with a median survival time of about a year with treatment. Due to the aggressive nature of these tumors and the tendency of gliomas to follow white matter tracks in the brain, each tumor mass has a unique growth pattern. Consequently it is difficult for neurosurgeons to anticipate where the tumor will spread in the brain, making treatment planning difficult. Archival patient data including MRI scans depicting the progress of tumors have been helpful in developing a model to predict Glioblastoma proliferation, but limited scans per patient make the tumor growth rate difficult to determine. Furthermore, patient treatment between scan points can significantly compound the challenge of accurately predicting the tumor growth. A partnership with Barrow Neurological Institute has allowed murine studies to be conducted in order to closely observe tumor growth and potentially improve the current model to more closely resemble intermittent stages of GBM growth without treatment effects.

Description
Nations have a vital interest in creating a citizenry with certain attributes and beliefs and, since education contributes to the formation of children's national identity, government authorities can influence educational curricula to construct their ideal citizen. In this thesis, I study the educational systems of Pakistan and Arizona and explore the historical and conceptual origins of these entities' manipulation of curricula to construct a particular kind of citizen. I argue that an examination of the ethnic studies debate in Tucson, Arizona, in conjunction with Pakistan's history education policy, will illustrate that the educational systems in both these sites are developed to advance the interests of governing authorities. Resource material demonstrates that both educational systems endorse specific accounts of history, omitting information, perspectives, and beliefs. Eliminating or reimagining certain narratives of history alienates some students from identifying as citizens of the state, particularly when contributions of their ethnic, cultural, or religious groups are not included in the country's textbooks.

Description
This project covered different components to strengthen Model United Nations organizations, especially programs in Arizona itself. The lack of strong programs in Arizona can be attributed in many ways to a lack of resources, and this project's work aims to bolster programs by providing some resources. The written component contains a write-up of a 2013 High School Model United Nations Conference at Arizona State University; a write-up of a 2014 Middle School Model United Nations Conference at Arizona State University; a guide on how to run such a conference, focused at the high school level; a university-level curriculum that integrates a Model United Nations organization into a classroom setting, including assignments and; a grade school lesson plan with seven lessons that focuses on teaches students about international relations and global affairs while preparing them for a Model United Nations conference.

Description
Previous research discusses students' difficulties in grasping an operational understanding of covariational reasoning. In this study, I interviewed four undergraduate students in calculus and pre-calculus classes to determine their ways of thinking when working on an animated covariation problem. With previous studies in mind and with the use of technology, I devised an interview method, which I structured using multiple phases of pre-planned support. With these interviews, I gathered information about two main aspects about students' thinking: how students think when attempting to reason covariationally and which of the identified ways of thinking are most propitious for the development of an understanding of covariational reasoning. I will discuss how, based on interview data, one of the five identified ways of thinking about covariational reasoning is highly propitious, while the other four are somewhat less propitious.

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
Electromyography (EMG) and Electroencephalography (EEG) are techniques used to detect electrical activity produced by the human body. EMG detects electrical activity in the skeletal muscles, while EEG detects electrical activity from the scalp. The purpose of this study is to capture different types of EMG and EEG signals and to determine if the signals can be distinguished between each other and processed into output signals to trigger events in prosthetics. Results from the study suggest that the PSD estimates can be used to compare signals that have significant differences such as the wrist, scalp, and fingers, but it cannot fully distinguish between signals that are closely related, such as two different fingers. The signals that were identified were able to be translated into the physical output simulated on the Arduino circuit.

Description
Interaction is key to education, as students who perform their own inquiry into a subject retain information longer. The field of interactive fiction, which emphasizes personal decision making and freedom of choice, is ripe for opportunity as it is relatively simple to develop and deploy to audiences of any size. However, few interactive fiction platforms exist with the openness and flexibility required for classroom use. My project attempted to create an interactive fiction platform that can be created for and engaged with by both teachers and students. This led to the creation of an interactive fiction platform that conforms to a variety of requirements, such as openness and compatibility across multiple platforms, and which can display meaningful content. This was accomplished by someone with a content area education background and only limited computer science experience, and shows promise for similar future endeavors.
