Description
This paper is the culmination of my creative project for graduation from Barrett, the Honors College at Arizona State University. The creative portion of the project consisted of researching Québécois (or French-Canadian) composers and specifically finding music for flute and piano. I wished to find pieces that could prove valuable in expanding the standard flute repertoire. My goal with this project was to shed light on some fairly unknown and certainly under-played pieces for flute and piano by French-Canadian composers and learn those pieces for my senior recital on March 2, 2020. This summary of the research experience and the process of recital preparation is intended to be a guide for flutists who may work on these pieces in the future and musicians on any instrument who take on a similar project of introducing new pieces to their instrument’s existing repertory.

Description
Chemoreception is an important method for an octopus to sense and react to its surroundings. However, the density of chemoreceptors within different areas of the skin of the octopus arm is poorly documented. In order to assess the relative sensitivity of various regions and the degree to which chemoreception is locally controlled, octopus arms were amputated and exposed to acetic acid, a noxious chemical stimulus that has previously been shown to elicit movement responses in amputated arms (Hague et al., 2013). To test this, 11 wild-caught Octopus bimaculoides (6 females, 5 males) were obtained. Acetic acid vapor was introduced in the distal oral, distal aboral, proximal oral, and proximal aboral regions of amputated arms. The frequency of the occurrence of movement was first analyzed. For those trials in which movement occurred, the latency (delay between the stimulus and the onset of movement) and the duration of movement were analyzed. The distal aboral and distal oral regions were both more likely to move than either the proximal oral or proximal aboral regions (p < 0.0001), and when they did move, were more likely to move for longer periods of time (p < 0.05). In addition, the proximal oral region was more likely to exhibit a delay in the onset of movement compared to the distal oral or distal aboral regions (p < 0.0001). These findings provide evidence that the distal arm is most sensitive to noxious chemical stimuli. However, there were no significant differences between the distal oral and distal aboral regions, or between the proximal oral and proximal aboral regions. This suggests that there may not be a significant difference in the density of chemoreceptors in the aboral versus oral regions of the arm, contrary to claims in the literature. The other independent variables analyzed, including sex, body mass, arm length, anterior versus posterior arm identity, and left versus right arm identity, did not have a significant effect on any of the three dependent variables analyzed. Further analysis of the relative density of chemoreceptors in different regions of the octopus arm is merited.

Description
Although the indigenous populations of the United States experience substantial disparities in health outcomes, little information is available regarding barriers to their access to specifically baby friendly hospitals and baby friendly services in the United States. Access is important because indigenous patients, especially women, have higher infant mortality and childhood obesity than their white counterparts.
This systematic review seeks to uncover potential barriers to baby friendly hospital services for indigenous patients in the United States. This systematic review analyzed the current literature from select databases published between 2000 and 2020 and narrowed literature down into studies deemed relevant because of their focus on the BFHI or equivalent and on indigenous patients. 303 studies were found using a specialized search string and then after evaluation under exclusion and inclusion criteria, 21 were identified for use in this review.
Analysis of these selected studies revealed trends of barriers as well as disparities in indigenous participation in current research. The conclusion of this review is that baby friendly and its “Ten Steps to Successful Breastfeeding” must be altered to allow for implementation in different cultural settings, especially for indigenous patients. Additionally, there is a need for additional research that focuses on indigenous patients in this setting and is written by members of that community. Increased representation from this community will enhance future work towards deconstructing the barriers preventing indigenous patients to access BFHI resources.

Description
Hypoxia-responses help coordinate the growth of oxygen-transporting tissues with the growth of other tissues during development. In Drosophila, hypoxia strongly affects development with flies being reared in a low oxygen environment showing smaller body sizes and diminished tracheal growth. The primary regulator of cellular hypoxic-responses is the hypoxia-inducible factor (HIF), and under normoxic conditions, HIF-alpha is hydroxylated by prolyl hydroxylase domain (PHD) on a proline residue inside the alpha leading to the proteins proteasome degradation downstream. However, in response to reduced oxygen, cells accumulate HIF- alpha, which then joins with the constituent HIF-beta in the cytosol, forming a HIF- alpha/beta heterodimer. Which, in turn, enters the nucleus and binds to hypoxic response elements, activating the hypoxic response genes. Hyperoxia has recently been shown to stimulates metabolic rates only at the last stage Drosophila's larval development (L3), indicating oxygen limitation occurs towards the end of development. Green fluorescent protein (GFP) was added to the oxygen-dependent domain of Drosophila HIF- Alpha (Sima) and a monomeric red fluorescent protein with a nuclear localization signal (mRFP-nls) was added to a protein under the same ubiquitin-69E promoter but is not affected by changing O2 levels. Using a Leica SP5 AOBS Spectral Confocal, third instar larvae were analyzed at the cellular level with attention focused on HIF- signaling in the central nervous system (CNS). L3 Drosophila were divided into groups of 0-12h, 12-24h, 24-48h, and 48-60h corresponding to their development. In each group, flies were either treated for 10-12 hours in 5% O2 or were left normoxic before fixation. What was overwhelmingly found is that HIF-signaling was most prominent during their early development (0-12h), with a significant decline as age increased (P=<0.001). There was also an observed hypoxic effect as animals treated in lower oxygen concentrations had significantly higher HIF signaling (P=<0.001). However, this effect still declines as larvae continued developing. This data supports the idea that internal hypoxia does not become severe during late third instar growth but may occur during the actual molt of the flies.

Description
In the event of a climate disaster, everything changes, but the places we’ve romanticized as a frontier will become new to us once again. New Sonoran is, in essence, an American story on a global problem. It draws on American pioneer/Old West/cowboy culture, the lasting effects of climate change denial, and the individualism that pervades American culture. I want to use this project to underscore the actual isolation of individualism, as well as create a new story that speaks to a problematic but evocative cultural history while accessing an uncertain future. For this project, I drew from a varied palette of media: comics, video games, and the pervasive cultural malaise that surrounds my current generation.
The work is based in anxieties, but its media influences are a strong indicator of tone and concept. At the very least, they helped me articulate why I wanted to work on a graphic novel on a post-climate change Sonoran. This desert that I’ve grown used to will change irrevocably, but it will be a new frontier to explore while the old will become a loss to mourn. This cycle of change is something I want to highlight in my work: we can worry, mourn, and fear, but there’s going to be something new.
New Sonoran is a graphic novel based upon the journey of Sage, a cartographer and anthropologist who travels the desert, annotating maps and studying a desert irrevocably affected by global climate change. As she catalogues the changes and losses in this new landscape, she learns how residents have adapted, and how people may still relate to the land.

Description
Agriculture is the second largest water consumer in the Phoenix Metropolitan region, after the municipal sector. A significant portion of the cultivated land and agricultural water demand is from the production of animal feed, including alfalfa (~69% of total cropland area), corn (~8), and sorghum (-3%), which are both exported and needed to support local dairy industry. The goal of this thesis is to evaluate the impacts on water demand and crop production of four different crop portfolios using alfalfa, corn, sorghum, and feed barley. For this aim, the Water Evaluation And Planning (WEAP) platform and the embedded MABIA agronomic module are applied to the Phoenix Active Management Area (AMA), a political/hydrological region including most of Phoenix Metro. The simulations indicate that the most efficient solution is a portfolio where all study crop production is made up by sorghum, with an increase of 153% in crop yield and a reduction of 60% of water consumption compared to current conditions. In contrast, a portfolio where all study crop production is made up by alfalfa, which is primary crop grown in current conditions, decreased crop yield by 77% and increases water demand by 105%. Solutions where all study crop production is achieved with corn or feed barley lead to a reduction of 77% and 65% of each respective water demand, with a portfolio of all corn for study crop production increasing crop yield by 245% and a portfolio of all feed barley for study crop production reducing crop yield by 29%.

Description
Many species follow networked roads. When roads are blocked, the obstruction must be circumnavigated, or traffic rerouted. We obstructed trails of the leaf-cutting ant Atta colombica and compared individual- and group-level circumnavigation as well as trail reuse following obstruction removal. Groups that circumnavigated the obstruction fastest were also the first to return to the original trail once the obstruction was removed. Also, nestward ants returned to using the original trail more quickly than outbound ants. Traffic rate was not related to speed of obstacle solving. The magnitude of reflective flow (reversing direction) explained much of the variation in obstacle-solving time, both comparing nestward versus outbound ants and variation across obstacles. Two other factors explaining variation in obstacle circumnavigation times were percentage of nestward ants carrying leaves and whether ants searched in the appropriate direction for the trail beyond the obstruction, possibly due to variation in the availability of navigation cues or motivation. Reflective flow allows highly-networked leafcutter trails to respond to blockages by using alternative cleared routes, with strength of navigation cues and motivation linked to foraging costs and benefits likely determining the effort expended to “solve” the obstacle versus give up.

Description
In recent years, it has become evident that American civic literacy is in a sharp decline. Many scholars agree that young adults are becoming increasingly less engaged in activities involving the application of civics and that this may hinder the democratic process. This thesis will focus on how historical perspectives can improve contemporary application of civics in order to solve the civic literacy crisis. The report will evaluate different approaches to improving civic engagement in order to gauge their effectiveness and the potential for their use in the United States. In analyzing the decline, we will look at work from the American Council of Trustees and Alumni (ACTA) like A Crisis in Civic Education and A Crucible Moment. Subsequently, we will provide a review of Megan McClure’s Tackling the American Civics Education Crisis and Robert D. Putnam’s Bowling Alone: America’s Declining Social Capital. We will present historical perspectives from the 19th and 20th century such as Thomas Jefferson, Alexis De Tocqueville and John Dewey in order to apply them to contemporary solutions for the decline. The contemporary perspectives of Harvard scholar Danielle Allen and various professors in the School of Civic and Economic Thought and Leadership (SCETL) at Arizona State University will be analyzed and critiqued. The results of our research prove that historical perspectives, when applied to contemporary solutions, are an effective way to bout the civic engagement crisis in the United States. This information can be used to alter the curriculum in the classroom to encourage and prepare students to become civically literate and engaged in order to protect the democratic process.

Description
The brain is considered the crux of identity, yet human behavior may be influenced by bacteria in gut microbiomes. Honeybees can exchange bacteria through their many social behaviors, making their microbiomes, and the effect they have on honeybee behavior, of interest. There is recent evidence suggesting the presence of bacteria existing in human brains, which can be investigated in honeybee brains due to their well-documented structure. The purpose of this study is to establish if lipopolysaccharide—a molecule on bacteria membranes—is present in the honeybee brain and if it colocalizes with vitellogenin—an immune mediator. Additionally, this study also seeks to establish the efficacy of embedding tissue samples in resin and performing immunohistochemistry for vitellogenin and lipopolysaccharide on sections.
