This paper details the process of implementing a schedule change for the Orbit Saturn, a neighborhood circulator bus in Tempe with poor on-time performance. It describes the methods used to estimate the true runtimes for the Saturn between timepoints, and measures the effectiveness of a schedule change that allows operators more time to traverse between timepoints. Changes were implemented on October 23, 2023, upon which there was a statistically significant decrease in average deviation from schedule, as well as a significant increase in the proportion of trips classified as “on-time” by Valley Metro. Increased on-time performance does not appear to be due to outside factors, such as seasonal changes in traffic.

For decades, society has held an innate fascination with serial murder and serial killers. The fascination lies in the motivations behind the actions and the way in which investigators apprehend them. The psychological field of investigative and behavioral psychology emerged to attempt to answer some of these questions and the investigative tool of behavioral profiling soon followed. Researchers have conducted comparison studies of male and female serial killers many times to understand what differentiates them. This research aims to answer another question: Are female serial killers more homogenous based on their profiles than male serial killers? The media portrays female serial killers in a very specific light, poisoners who kill due to revenge or money, but how well does this portrayal actually hold up when analytically examined? This research compiled case studies of fifteen male and fifteen female serial killers based on twenty-six characteristics and profiled each according to three different typologies to determine how homogenous these groups actually are. This research can help assist investigators and the public to better understand the diversity of these types of offenders and be able to determine who these offenders are.

The food-insecure population in the United States is significant, with a disproportionately large food insecure population being college students. Food insecurity is an issue of great concern not only because of the presence of malnourishment, but especially because of the many negative effects on health it can have on individuals that come as a result of malnourishment. In addition to the many health issues that can arise, food insecurity has also been found to be correlated with poor academic performance in school which is especially important when it comes to the food insecure college student population. Among the many reasons that college students might be food insecure, one issue that is explored is that college students do not have the capabilities to prepare adequate meals for themselves, so their lack of ability to do so contributes to their food insecurity. One way to combat this issue is to encourage college students to take the initiative to learn how to cook meals. A survey evaluated the food insecurity status of undergraduate ASU students and explored various food habits such as meal preparation, fresh produce consumption, and various influencing factors and obstacles of eating healthy, among others. Results found that those who identified as food insecure were less likely to cook meals for themselves as often as those who are not food insecure, nor were they as likely to consume fresh produce as those who are not food insecure. Additionally, all students have reported improved academic performance and/or physical/mental wellbeing. With the support that eating healthy meals is important for college students’ academics and physical and mental wellbeing, as is having the knowledge on how to prepare healthy meals, a fresh produce resource guide was created with the purpose of encouraging ASU students to learn the basic skills of cooking and meal preparation.

Bone loss affects millions of people every year posing a major public health problem. Currently, autograft and allograft bones are the only options for treating bone loss. Although, they pose many limitations including donor availability, immunogenicity risks, and the potential to carry a risk of disease and/or infection transmission to name a few. Therefore, there is a pressing clinical need to create a novel treatment that will promote bone repair. Alpha-ketoglutarate (aKG) was investigated as it plays an important role in cellular energy metabolism as a key intermediate in the Krebs cycle. It has been shown to stimulate the production of collagen in the bone repair process. However, controlling the release of aKG is important in being able to control where and how much new bone growth is stimulated. To address this aKG was delivered via a hyaluronic acid hydrogel and its release was controlled via the degradation of poly(alpha-ketoglutarate) microparticles (paKG MPs). paKG MPs were synthesized and characterized based on size, shape, and uniformity. The release of aKG from paKG MPs was evaluated, as well as the addition of paKG MPs into norbornene functionalized hyaluronic acid and maleimide functionalized hyaluronic acid hydrogels. Initial cell work was also done to grow osteoblasts for future work. It was found that paKG MPs were of the desired size and shape. The release of aKG from the paKG MPs was found to be sustained. The addition of paKG MPs in norbornene functionalized hyaluronic acid (NorHA) was found to be ineffective due to the opaqueness of the MPs. Maleimide functionalized hyaluronic acid (MaHA) hydrogels were chosen as an alternative delivery system for this reason. Future tests will be done on the addition of paKG MPs into MaHA hydrogels. Osteoblasts were also successfully grown and will be used in future studies.

Many would contend that the United States healthcare system should be moving towards a state of health equity. Here, every individual is not disadvantaged from achieving their true health potential. However, a variety of barriers currently exist that restrict individuals across the country from attaining equitable health outcomes; one of these is the social determinants of health (SDOH). The SDOH are non-medical factors that influence the health outcomes of an individual such as air pollution, food insecurity, and transportation accessibility. Each of these factors can influence the critical illnesses and health outcomes of individuals and, in turn, diminish the level of health equity in affected areas. Further, the SDOH have a strong correlation with lower levels of health outcomes such as life expectancy, physical health, and mental health. Despite having influenced the United States health care system for decades, the industry has only begun to address its influences within the past few years. Through exploration between the associations of the SDOH and health outcomes, programming and policy-making can begin to address the barrier to health equity that the SDOH create.

2018, Google researchers published the BERT (Bidirectional Encoder Representations from Transformers) model, which has since served as a starting point for hundreds of NLP (Natural Language Processing) related experiments and other derivative models. BERT was trained on masked-language modelling (sentence prediction) but its capabilities extend to more common NLP tasks, such as language inference and text classification. Naralytics is a company that seeks to use natural language in order to be able to categorize users who create text into multiple categories – which is a modified version of classification. However, the text that Naralytics seeks to pull from exceed the maximum token length of 512 tokens that BERT supports – so this report discusses the research towards multiple BERT derivatives that seek to address this problem – and then implements a solution that addresses the multiple concerns that are attached to this kind of model.

This paper seeks to highlight the strong correlation and potential causation between the presence of physical community bank branches in rural communities and local economic outcomes like payroll, employment, and establishments in a given region. To do this, I conduct a two-part analysis involving a fixed effects model with data from across the US and a regression discontinuity model of a subset of the data in parts of Delaware and Maryland. Overall, my results show a significant strong correlation between the number of bank branches in a region and the expected percent changes in economic outcomes, but I lack the results to claim causality between the opening or closure of a bank branch and changes in the local economy. This has relevance in understanding the need for physical bank branches as changes in the financial industry since the 2008 Financial Crisis, like online banking, have continued to accelerate.
