    • The 2012 Presidential Election Gender Gap

      Norrander, Barbara; Caicedo, Andrea (The University of Arizona., 2015)
      The gender gap in presidential elections has been an important part of American politics for the past decades. This phenomenon in politics refers to the differences of men and women in party identification and voting behavior. This paper explains the origins of the gender gap dating back to the 1980s. It explains the patterns and analyzes the most significant issues in each presidential election. Finally, it analyzes the gender gap in the 2012 presidential election. It focuses on the issues that had the biggest difference and it explains why some issues are more susceptible to having a greater gender gap.
    • 2015-2016 UA|ASME HUMAN POWERED VEHICLE PROJECT: MAGNUM

      Pine, Gerald; LEISTER, DAVID EDWARD (The University of Arizona., 2016)
      The American Society of Mechanical Engineers (ASME) hosts the annual Human Powered Vehicle Challenge (HPVC), in which student design teams from universities and colleges around the world design, build, and compete human powered vehicles. A human powered vehicle is just any vehicle whose motive power comes from the exertion of its driver(s). The University of Arizona’s (UA) entry in the 2016 HPVC West, Magnum, succeeds Blue Steel (2013), Le Tigre (2014), and Ferrari (2015). It is the most ambitious project undertaken by the UA human powered vehicle team, featuring a carbon fiber/aluminum hybrid frame and full fairing, and a custom built steering system. An onboard electronics suite includes turn signals, a traffic horn, and a novel Roll Alert System, an Android app developed by the team to alert everyone in the event of a vehicle rollover or crash. Both the mechanical and electronic systems were designed and built from the ground up by this year’s team. Magnum is also the best-performing UA human powered vehicle in recent history, earning Top 10 ranks in the 2016 HPVC West’s Design and Innovation categories, and 13th overall.
    • 2016 CHICAGO QUANTITATIVE ALLIANCE INVESTMENT CHALLENGE: U OF A CQA TEAM - INVESTMENT STRATEGY

      Singh, Arvind; CARLSON, JONATHAN ANDERS (The University of Arizona., 2016)
      For my finance, honors thesis I participated in the 4th annual CQA Investment Challenge. The goal of the challenge is to successfully manage an equity long-short, market neutral portfolio (hedge fund). I worked on a team with three other guys from the Applied Portfolio Management class to invest and manage $20,000,000 of hypothetical money. Our investment horizon ran from October 30, 2015 – April 1, 2016. The stock universe we had access to was the Russell 1000, which mainly consists of the highest-ranking large cap stocks in the US equity market. Thirty-one teams from different universities were judged at the end of the competition on absolute return rank, adjusted return rank (the Sharpe ratio) and evaluation of the team video, which discussed investment strategy. The University of Arizona team achieved an absolute return of 6.47%, Sharpe ratio of 0.36 and abnormal return (alpha) of 20.05%. We finished with a ranking of 7th place out of 31 participating schools.
    • 2017 Chicago Quantitative Alliance Investment Challenge: University of Arizona CQA Investment Strategy

      Cederburg, Scott; To, Kham Hong; Hascalovici, Hilla; Bateman, Spencer; Recchion, Edward; Recchion, Charles (The University of Arizona., 2017)
      The CQA challenge is a 6 month competition that starts in October and ends in March. In this competition, student teams from 54 universities across the world are competing to build a long-short, market neutral equity portfolio that would generate the most risk-adjusted return in the given time horizon while operating under a few specific portfolio constraints. Each team is ranked against each other based on risk-adjusted return and sharpe ratio. Our team consisted of 5 senior finance students at the University of Arizona. Together, we developed our own unique market outlook and portfolio strategy in order to successfully invest $1,000,000 in (hypothetical) capital. We used industry tilts towards financials, energy, and consumer discretionary sectors and factor tilts towards momentum and value stocks as our main drivers of return while minimizing market exposure by keeping our beta between -0.25 and +0.25. The University of Arizona finished the competition in first place in overall portfolio ranking with a return of 12.23% and in fifth place for sharpe ratio at 1.43.
    • 2017 Chicago Quantitative Alliance Investment Challenge: University of Arizona CQA Team – Investment Strategy

      Cederburg, Scott; Bateman, Spencer Michael (The University of Arizona., 2017)
      In order to complete my honors thesis in finance, I joined a team of five finance students in participating in the 2017 Chicago Quantitative Alliance Investment Challenge. The challenge required teams to create $2,000,000 market-neutral investment portfolios utilizing both long and short equity positions. From November 8th until March 31st, our team actively managed our equity portfolio by selecting stocks from a 1,000 stock investment universe, while 53 other teams from universities around the world competed against our portfolio using measures of absolute return, risk-adjusted return, and a team video explaining our performance and investment strategy. By utilizing a strategy contingent on both industry bets and style exposures to value and momentum, the University of Arizona team has achieved an absolute return of 12.23% and a Sharpe Ratio of 1.43.
    • 2020 AIAA DESIGN, BUILD, FLY COMPETITION DESIGN REPORT

      Redford, Gary; Dahl, Kirk (The University of Arizona., 2020-05)
      The Design, Build, Fly University of Arizona 2020 design team developed a remote-controlled aircraft for the international 2020 American Institute of Aeronautics and Astronautics Design/Build/Fly competition on April 16-19 in Wichita, Kansas. The design emphasized speed, cargo carrying capacity, as well as deployment and detachment of a banner. The team constructed a 58-inch wingspan, low-wing, T-tail aircraft with twin engines. The design features an integrated passenger bay inside the fuselage with oversized control surfaces for improved maneuverability when carrying many passengers. A banner deployment and detachment mechanism allows for a banner to deploy mid-flight and detach from the aircraft before landing. The twin-engine configuration provides sufficient stability and properly orients the banner in flight. Large propellers provide both ample thrust for multiple mission types and turbulent flow over the wings for prolonged lift generation. Preliminary prototyping and flight testing verified the design as stable and flightworthy. Final testing evaluated and optimized propulsion, structures, and payload systems and enhanced mission scoring potential.
    • 2023 CFA RESEARCH CHALLENGE

      Kinnear, Daniel; Jepson, William (The University of Arizona., 2023)
      The CFA Research Challenge is an annual global competition for university students in finance, accounting, and business. The competition aims to provide students with real-world experience in equity analysis and financial modeling, as well as to encourage the development of soft skills such as teamwork, communication, and presentation skills. Each participating university forms a team of three to five students who conduct original research and analysis on a publicly traded company. The students then prepare a detailed written report and present their findings to a panel of judges. The winning team from each local competition advances to the regional and global finals. The criterion for the written report includes an analysis of the company's industry and competitive positioning, financial analysis, valuation analysis, and investment recommendation. The report should also include an executive summary, a conclusion, and a list of references. The research required for the report includes the analysis of financial statements, industry reports, and news articles.
    • 30/30 Museum & Park: Engaging Artifacts

      Kothke, Michael; Kwolek, Queston Aureon (The University of Arizona., 2017)
      This project is located in the St. Henri neighborhood along the Lachine Canal in Montreal, Quebec. Industrial artifacts along the canal are culturally and historically significant to the people of Montreal. These artifacts are currently disconnected from public access – residents and tourists should be able to fully engage with them. The abandoned malting plant site has the potential to become an engaging destination that visitors want to explore. The proposal honors and reimagines the site’s industrial infrastructure and introduces valuable public amenities to the Lachine Canal. The 30/30 concept refers to the juxtaposition of the existing thirty silos and proposed thirty mounds. Generated from the volumetric capacity of the silos and natural form of grain, the mounds support vegetation to restore the sites pre-industrial presence of nature. Museum functions and public spaces are integrated into both the silos and mounds, resulting in an activity-driven experience for visitors that is centered on exploration and discovery. The proposal has the potential to host events, exhibitions, and outdoor activities year-round. By allowing guests to "trespass" through urban artifacts, they are invited to discover the mysterious atmosphere and cultural significance of the former factory and the site’s new public amenities.

    • 5-FU Chemotherapy Failure in Some Colorectal Cancer Patients with Microsatellite Instability

      Doetschman, Thomas; McEvoy, Megan; Coggins, Si'Ana Apri (The University of Arizona., 2015)
      Human colorectal cancer (CRC) is the third most commonly diagnosed cancer as well as the second leading cause of cancer mortality in the United States. The hypothesis to be tested in this study is that the loss of TGFβ signaling causes overexpression of the uridine phosphorylase (UP) gene in human CRC when treated with 5-fluorouracil (5-FU), a common chemotherapeutic reagent. As a result, 5-FU may be metabolized via the RNA pathway, causing an increase in host-toxicity. Conversely, a mutation in the KRAS gene may drive the reaction towards the antitumor, DNA metabolic pathway. This mechanism would explain the ineffective nature of 5-FU-based treatments on tumors, some of which are TFGβ signaling-deficient, that are usually characterized as microsatellite instability high (MSI-H). If so, situational inhibition of UP may increase the intended anti-tumor activity of the 5-FU treatment while decreasing host-toxicity in this subcategory of MSI-H tumors, thus allowing only patients whose tumors have a 5-FU-susceptible genetic profile to be treated successfully with 5-FU based therapy. Cancerous cell lines containing different combinations of TGFBR2 and KRASᴳ¹³ᴰ mutations will be cultured and photographed. The cell lines Hke3 and Hkh2 contain a TGFBR2 mutation and have a morphological pattern that closely resembles the colonic mucosa while the HCT116 cell line contains both TGFBR2 and KRASᴳ¹³ᴰ mutations and has less structured morphology. Following culturing, UP and TP mRNA expression levels in all cell lines will be determined through reverse transcriptase (RT)-PCR and normalized to β-actin. If the hypothesis is supported, and then verified in patients, personalized therapy can be used to determine whether 5-FU should be administered in colorectal cancer cases in which KRASᴳ¹³ᴰ and TGFBR2 mutations are present or absent.
    • A CACHING EVALUATION OF THE HADOOP DISTRIBUTED FILE SYSTEM

      Newberry, Eric Evan Michael (The University of Arizona., 2018)
      The Hadoop Distributed File System (HDFS) is a distributed le system used to support multiple widely-used big data frameworks, including Apache Hadoop and Apache Spark. Since these frameworks are often run across many compute nodes, it is possible that multiple nodes will read the same data. In addition, since data is replicated across multiple nodes for storage, the same data will be written multiple times across the network. In this paper, we conduct an evaluation of the caching potential present in HDFS in order to determine if in-network caching, particularly of the type seen in Named Data Networking (NDN), would reduce the amount of tra c seen in a Spark cluster network, as well as the average load on each data storage node. Our results show that for most benchmarks running on Apache Spark, a majority of the large read operations were done to transfer the Spark and application dependency libraries to each compute node. In addition, there was not a signi cant amount of read tra c in the network for most of the applications we evaluated, making the bene ts of in-network caching for HDFS questionable.
    • A CHANGE IN HEART: A REVIEW OF THE EFFECTS OF SARS-COV-2 ON THE CARDIOVASCULAR SYSTEM

      Cohen, Zoe; Cusson, Alycia (The University of Arizona., 2023)
      Within months of its first appearance in Wuhan, China, the COVID-19 virus, referred to as SARS-CoV-2, had spread across the globe, infecting hundreds of millions of individuals. SARSCoV-2, one of many viruses in the severe acute respiratory syndrome coronavirus family, is known to cause a variety of flu-like symptoms including fever, coughing, and shortness of breath. For many patients with pre-existing conditions, particularly those with previous cardiovascular conditions, COVID-19 infection is often more severe and may lead to hospitalization. This review aims to explore these pathological effects of the SARS-CoV-2 virus on the cardiovascular system. We will begin by covering an overview of the cardiovascular system and blood pressure regulation. We will then explore the interaction between SARS-CoV-2 and the renin-angiotensin-aldosterone system (RAAS), which is responsible for producing changes in blood pressure within the body. SARS-CoV-2 binds to ACE2, one of the receptors in the ACE2-Ang(1-7)-Mas axis of RAAS. It is thought that this downregulation in the surface expression of ACE2—due to viral uptake—contributes to the cardiovascular complications experienced by high-risk patients. This review will then shift to the effects of COVID-19 on specific cardiovascular conditions including hypertension, heart failure, and atherosclerosis. Finally, we will conclude with an assessment of the current research regarding continued usage of ACE inhibitors and ARBS in patients with COVID-19.
    • A Classical Insight Into the Separation Between Church and State

      Waddell, Philip T.; Videla, Gabrielle Marie (The University of Arizona., 2018)
      This paper connects events of the late Roman Republic with the United States of America’s principle of separation of Church and State. Many scholars find similarities between the Roman Republic and the U.S., but do not know the depth of connection or how the founding of the nation was impacted by the classical world. In the first sections of this paper I define the Roman state cult and examples of how it was abused during the turbulence of the late Republic. The next section describes the classical education the Founding Fathers received. There follows an indepth explanation of the creation and support of the principle of separating church and state during the founding of the United States. To conclude, connections are drawn between that principle of separation and the troubling events of the late Roman Republic that the Founding Fathers would have read from classical authors. It is hoped that this paper shows how a study of the classical world offers modern scholars a chance to understand the modern world.
    • A CLOSE READING OF WENDELL BERRY'S THE FARM

      Melillo, John; Wood, Burke (The University of Arizona., 2023)
      This thesis will be a close reading of Wendell Berry’s 1995 poem, The Farm. This work is a long-form poem in which Berry outlines the tasks and everyday to-dos of life on his farm. He also includes long descriptions of the land on which his farm occupies. In this essay, I will argue how Berry is commenting on the dialectic exchange between the act of saying and the act of doing. This thesis will demonstrate to readers how Berry makes this assessment through the lens of genre, his personal beliefs reflected in the work, and how those beliefs relate to greater philosophy on labor. In my pursuit of these topics, I have found that Berry’s The Farm is classified as a georgic pastoral as it grapples with the way that pastoral lends itself to the language of describing the land, while the georgic lends itself to describing how to tend to that land. I also found the way in which Berry’s personal beliefs are put into action by the way he writes his poetry and the work he does on his farm. And finally, I concluded how Berry’s actualized labor and management of the farm is somewhat in line with Marxist beliefs on community and the alienation of labor.
