Description
The purpose of this project was to interview eleven Hubert H. Humphrey Fellows at the Walter Cronkite School at Arizona State University through a podcast series titled “The Global Journalist Roundtable”. During a two month period, I interviewed the eleven Fellows and through a keyword analysis of the transcripts of each interview, I determined several themes which according to the Fellows were important aspects of global media. Those themes were education, innovation, social media as a disrupter to news verifiability, polarization, censorship, the importance of truthful news, and leadership. The reason for interviewing the Humphrey Fellows specifically was due to my sheer curiosity, respect, and admiration for them as professionals in the global media industry.

Description
This thesis will cover the basics of 2-dimensional motion of a parafoil system to determine and
design an altitude controller that will result in the parafoil starting at a location and landing within the
accepted bounds of a target location. It will go over the equations of motion, picking out the key
formulas that map out how a parafoil moves, and determine the key inputs in order to get the desired
outcome of a controlled trajectory. The physics found in the equations of motion will be turned into
state space representations that organize it into differential equations that coding software can make
use of to make trajectory calculations. MATLAB is the software used throughout the paper, and all code
used in the thesis paper will be written out for others to check and modify to their desires. Important
aspects of parafoil gliding motion will be discussed and tested with variables such as the natural glide
angle and velocity and the utilization of checkpoints in trajectory controller design. Lastly, the region of
attraction for the controller designed in this thesis paper will be discussed and plotted in order to show
the relationship between the four input variables, x position, y position, velocity, and theta.
The controller utilized in this thesis paper was able to plot a successful flight trajectory from
10m in the air to a target location 50m away. This plot is found in figure 18. The parafoil undershot the
target location by about 9 centimeters (0.18% error). This is an acceptable amount of error and shows
that the controller was a success in controlling the system to reach its target destination. When
compared to the uncontrolled flight in figure 17, the target will only be reached when a controller is
applied to the system.

Description
This project aims to study the relationship between model input parameters and model output accuracy of the Tool for Automation of Computational Aerodynamics of Airfoils (TACAA). The input parameters of study are Mach number and Reynolds number, and inputs are tested through three flight speed regimes and from laminar to turbulent flow. Each of these input parameters are tested for the NACA 0012 and SC-1095 airfoils to ensure that the accuracy is similar regardless of geometric complexity. The TACAA program was used to run all simulation testing, and its overall functionality is discussed. The results gathered from the preliminary testing showed that the spread of variable input data points caused data gaps in the transonic regime results, which provided motivation to conduct further testing within the transonic region for both airfoils. After collecting all TACAA results, data from wind tunnel testing was compiled to compare. The comparison showed that (1) additional testing would be necessary to fully assess the accuracy of the results for the SC-1095 airfoil and (2) TACAA is generally accurate for compressible, turbulent flows.

Description
This paper examines the fundamental problem statement of: How can the hotel & resort industry resist and overcome the new competitive challenge that the sharing economy and Airbnb have imposed on it? This wasn’t a problem up until this past decade, as hotels had long been the world’s main solution for individuals looking for a place to stay in exchange for a fee. That has changed nowadays as the rise of the sharing economy has created a new, fast-growing demand for Airbnb in the hospitality industry. We have witnessed powerful companies die as a result of not taking disruptive technology seriously, as seen with Blockbuster and Kodak; however, we have also seen impressive reactions to disruptive technology in other cases such as Walmart and Alibaba that use it to enhance the customer experience. Hotels arose from humble beginnings and progressively became more than just a place to sleep. This is evidenced by the progression from 16th century humble inns to large luxury hotels in the 19-20th century to many hotels being significant tourist attractions themselves nowadays. While some factors such as security, hygiene, and consistency currently remain on the hotel industry’s side, the main factors fueling the growth of Airbnb are closely tied to consumer preferences and Airbnb’s ability to create unique, authentic experiences. A questionnaire with 756 responses from ASU students was conducted for this project’s primary research. The results concluded that this demographic travels often, slightly prefers hotels over Airbnb, and values location, convenience, and cost the most. Results were consistent with findings discussed in literature, since the bulk of respondents said they look at Airbnb for low-cost options and hotels for high-end options. Hotels reign supreme in the high-end market and benefit from their location and convenience factors, but Airbnb might have an opportunity to leverage their attractive capabilities while also incorporating some of hotels’ best aspects. This can cause the preference of hotels over Airbnb to diminish further going forward. Hotels can combat Airbnb in multiple ways. One is for hotel chains to customize more hotels to fit the local destination like Airbnb rather than keeping a more standardized vibe and design across all locations. Another is to continue focusing on creating unmatched service experiences in the high-end market that are hard for Airbnb to replicate. A third one is to implement more competitive pricing relative to Airbnb during peak seasons across different cities. Finally, given the increased awareness on hygiene and health that the COVID-19 crisis will likely bring after the pandemic, hotels should put greater emphasis on their hygiene factor when conducting publicity efforts, since this remains in favor of hotels rather than Airbnb and can attract customers who are still reeling with fear from the pandemic. All of this can help hotels to retain their crucial competencies while leveraging Airbnb’s competencies to create an incredible customer experience that is the best of both worlds. All of it prevent the hotel industry from going down a darker path than it has gone through before.

An understanding of aerodynamics is crucial for automobile performance and efficiency. There are many types of “add-on” aerodynamic devices for cars including wings, splitters, and vortex generators. While these have been studied extensively, rear spoilers have not, and their effects are not as widely known. A Computational Fluid Dynamics (CFD) and wind tunnel study was performed to study the effects of spoilers on vehicle aerodynamics and performance. Vehicle aerodynamics is geometry dependent, meaning what applies to one car may or may not apply on another. So, the Scion FRS was chosen as the test vehicle because it is has the “classic” sports car configuration with a long hood, short rear, and 2+2 passenger cabin while also being widely sold with a plethora of aftermarket aerodynamic modifications available. Due to computing and licensing restrictions, only a 2D CFD simulation was performed in ANSYS Fluent 19.1. A surface model of the centerline of the car was created in SolidWorks and imported into ANSYS, where the domain was created. A mesh convergence study was run to determine the optimum mesh size, and Realizable k-epsilon was the chosen physics model. The wind tunnel lacked equipment to record quantifiable data, so the wind tunnel was utilized for flow visualization on a 1/24 scale car model to compare with the CFD.
0° spoilers reduced the wake area behind the car, decreasing pressure drag but also decreasing underbody flow, causing a reduction in drag and downforce. Angled spoilers increased the wake area behind the car, increasing pressure drag but also increasing underbody flow, causing an increase in drag and downforce. Longer spoilers increased these effects compared to shorter spoilers, and short spoilers at different angles did not create significantly different effects. 0° spoilers would be best suited for cases that prioritize fuel economy or straight-line acceleration and speed due to the drag reduction, while angled spoilers would be best suited for cars requiring downforce. The angle and length of spoiler would depend on the downforce needed, which is dependent on the track.

Less than a full year ago, Cronkite News at ASU’s Walter Cronkite School launched ‘Cronkite News to Go’ (CN2GO). An innovative new way to deliver news content to those in Arizona, and across the country. This Barrett, Creative Project, focuses on the Best Practices for how to build a CN2GO Flash Briefing from start to finish. The booklet inclusion incorporates a number of step-by-step checklists for creating audio content, with the hope that it's something any Cronkite News reporter would be able to pick-up and learn from. This booklet also addresses the importance of CN2GO. It describes how these audio briefings are a great example of innovation, as well as a fantastic learning tool for future audio reporters.
This project also discusses possible solutions for how to maintain CN2GO long into the future. As old students graduate, and new ones join the team, this project will need to be sustained. The presentation portion of this Creative Project describes a number of potential improvements that could possibly be made to CN2GO, in order to better the entire process. These improvements are suggestions compiled from the personal experiences of student journalists tasked with creating CN2GO’s weekly. The presentation also includes a section devoted to how Cronkite News’ Flash Briefings can be continued over breaks in the school year. Spring breaks, Winter breaks, holidays, for example. These suggestions were made drawing from experimentation that was done with the CN2GO format in collaboration with this project.
The central purpose for this project was to take an existing idea and see how it can be prolonged and sustained far into the future. It can be used as an evolving learning tool for many iterations of Cronkite News reporters and producers to come.

The 21st century has brought significant changes to American consumers through technological advancements, social medias, and changing public sentiments. The sport industry in particular has been largely unable to capitalize on these changes due to the traditional nature of sports.
Keyball™ is the new 21st century sport specifically designed to have the greatest spectator appeal in this modern age. With focus on athleticism, parity, theatrical/emotional engagements, and community impact, Keyball™ aims to create a fan experience that is not achievable by other professional sports leagues. By design, there is high skillset carryover from other sports, ensuring tremendous talent will always be available, and fans of many different sports will find Keyball™ attractive to watch and follow.
The professional sports industry has been dominated by only a few players for the past century. Due to the traditional nature of sports, innovation is hard to implement in professional leagues. Tackle football is A. incredibly dangerous, causing broken bones, torn ligaments and tendons, and serious brain damage (concussions, CTE) at high rates. B. Football is low scoring and C. the pace of play is very slow. Basketball by nature A. overwhelmingly rewards height or verticality. It also B. lacks physicality and C. parity (NBA level). D. The foul system is flawed and easily exploited, dampening the end of games.
Keyball™ is positioned to A. be much more violent than basketball/soccer/baseball, while being significantly safer than tackle football. In addition, B. the speed of play is much faster than football, similar to a soccer/basketball live play style. C. Keyball™ is high scoring (like basketball, unlike football and soccer) and features much more dynamic/exciting scoring opportunities than traditional team sports. Keyball™ D. unifies the highly entertaining skillsets of soccer players (foot skill) with basketball/football players (explosiveness & hand coordination). E. Keyball™ has inherent double meaning that alludes to gambling (Keyball™ Wager) yet still promotes charity, selflessness, and American values (capitalism, sportsmanship, teamwork).

Innovation Space is Arizona State University’s capstone style project in which upper division students gain real experience in the startup and product development world by solving real-world problems. These problems were presented to my team by sponsor; LG Electronics. Innovation Space uniquely offered an interdisciplinary glance into “real life” in the months before college graduation. Students are placed on teams with designers, engineers, sustainability majors, and business majors to better reflect the real world. As a business student of this program, I was able to gain and share knowledge from my teammates’ distinct backgrounds; as well as gain the interdisciplinary experience that is key to a college education, specifically to a business student. LG Electronics, our sponsor, brought our team the task of expanding their product line in their “wind comfort” business unit. LG Electronics has created a lighter, more efficient motor for a fan; likely as an answer to their dominating fan competitor, Dyson. LG Electronics wanted to see what our team could do to alter the way people cool their homes, and we responded with three original ideas: a modular, non-centralized A/C unit; a hands-free hair dryer; and a portable 360 degree fan. Our team developed the latter product, and named it Torus. The product was developed over the course of August 2018 to May 2019, ending in a working prototype formally presented to the sponsor and industry professionals. On top of this project, I was directed to also analyze the Innovation Space program for its benefits and drawbacks to a business degree from the W.P. Carey School of Business.

This research highlights how problems that women face at the structural, social, professional and individual level impact their business success, personal growth, and the business economic environment. The first section of the paper provides a global view about gender gaps and challenges. The second section is narrowed down to the city of Baños de Agua Santa in Ecuador where the findings were sought through a grounded theory research. After the analysis of the findings, a business model has been developed which addresses the major challenges and problems that women and the city are currently encountering. The ultimate purpose is to implement the project in the city; it promotes entrepreneurial education, innovation, association, and personal growth. The overall research is a cutting-edge study as it emphasizes that the business success of women entrepreneurs is not solved by one big fixed but more through a holistic solution.

Description
An experimental investigation was conducted to calculate the aerodynamic drag on a cyclist wearing different types of clothing. The different outfits worn for this experiment were a professional skinsuit, a professional cycling kit, a t-shirt and shorts, and a long-sleeved flannel and jeans. The aerodynamic drag was ultimately found using the coast down method, a process in which a cyclist increases their speed to a chosen maximum threshold, and upon reaching this speed, ceases the pedal stroke and maintains the aero position until the bicycle comes to a stop. The data was gathered using an AeroPod, speed sensor, and GPS unit. The data gathered was imported into Excel for data analysis. The average CdA values at race speed (26-30 ft/s) for the skinsuit, cycling kit, t-shirt and shorts, and flannel were calculated to be 4.180 ft2, 3.668 ft2, 4.884 ft2, and 4.223 ft2, respectively. These race speed averages were found using data from three separate Ironman Triathlons. The cycling kit was found to be the most aerodynamic at the race speed. The results of this study reveal that cycling apparel can only be optimized for a small range of speeds and cycling outside of this optimal range delays the initiation of the reduction of boundary layer separation, thus resulting in more critical time spent in the flow transition region. The skinsuit’s performance was more aerodynamically efficient than the cycling kit at speeds greater than 36.8 mph. The cycling kit is more aerodynamic for speeds slower than 36.8 mph. The slickness of the skinsuit was found to be detrimental to the cyclist’s aerodynamic drag, as the lack of roughness on the skinsuit prevented the initiation of turbulent flow, which results in a decrease in drag. Overall, the experiment confirmed the hypothesis that a cyclist is more aerodynamic when wearing cycling apparel as opposed to casual, loose-fitting clothing.
