Popular culture has a longstanding tendency for being affected by, and reversely affecting, politics. Films, in particular, can exist as either purse “escapism” or heady pathways for political commentary. During the Second World War, governments in both the United States and Great Britain used film as a vessel for their own messages, but after the war ended, the two nations allowed their respective film industries more free expression in commenting on wartime and post-war politics. Film also provided particularly vivid political commentary during, and in the years immediately following, the Cold War. Though film has a longstanding history of being a force for political commentary, the medium’s specific engagement with the Cold War holds particular significance because works produced by the two nations’ film industries paralleled the social trend toward political activism at the time. While films produced in the UK and the United States in the 1960s addressed a wide range of contentious political issues, a huge body of work was spurred on by one of the most pressing political tensions of the time: namely, the Cold War.
The United States and Great Britain were major, allied forces during the Cold War. Despite their allied positions, they had unique politico-social perspectives that greatly reflected their immediate involvement in the conflict, in addition to their respective political histories and engagement in previous wars. As the Cold War threat was a large and, in many ways, incomprehensible one, each country took certain elements of the Cold War situation and used those elements to reflect their varied political social positions to a more popular audience and the culture it consumed.
In turn, filmmakers in both countries used their mediums to make overarching political commentaries on the Cold War situation. This analysis looks at five films from those countries during the 1960s, and explores how each representation offered different, often conflicting, perspectives on how to “manage” Cold War tensions, while simultaneously reflecting their conflicted culture and political decisions. The films analyzed reveal that each country focused on contrasting perceptions about the source of the threat posed by Soviet forces, thus becoming tools to further promote their distinct political stances. While the specifics of that commentary changed with each filmmaker, they generally paralleled each country’s perspective on the overall Cold War atmosphere. The British message represented the Cold War as a very internal battle—one that involved the threat within UK borders via the infiltration of spies the tools of espionage. In contrast, the American films suggest that the Cold War threat was largely an internal one, a struggle best combatted by increasing weaponry that would help control the threat before it reached American borders.

Description
The apparent phenomenon of the human eye retaining images for fractions of a second after the light source has gone is known as Persistence of Vision. While its causes are not fully understood, it can be taken advantage of in order to create illusions which trick the mind into perceiving something which, in actuality, is very different from what the mind portrays. It has motivated many creative engineering technologies in the past and is the core for how we perceive motion in movies and animations. This project applies the persistence of vision concept to a lesser explored medium; the wheel of a moving bicycle. The motion of the wheel, along with intelligent control of discrete LEDs, create vibrant illusions of solid lines and shapes. These shapes make up the image to be displayed on the bike wheel. The rotation of the bike wheel can be compensated for in order to produce a standing image (or images) of the user's choosing. This thesis details how the mechanism for conducting the individual LEDs was created in order to produce a device which is capable of delivering colorful, standing images of the user's choosing.

Description
RRAM is an emerging technology that looks to replace FLASH NOR and possibly NAND memory. It is attractive because it uses an adjustable resistance and does not rely on charge; in the sub-10nm feature size circuitry this is critical. However, RRAM cross-point arrays suffer tremendously from leakage currents that prevent proper readings in larger array sizes. In this research an exponential IV selector was added to each cell to minimize this current. Using this technique the largest array-size supportable was determined to be 512x512 cells using the conventional voltage sense amplifier by HSPICE simulations. However, with the increase in array size, the sensing latency also remarkably increases due to more sneak path currents, approaching 873 ns for the 512x512 array.

Description
The artificial neural network is a form of machine learning that is highly effective at recognizing patterns in large, noise-filled datasets. Possessing these attributes uniquely qualifies the neural network as a mathematical basis for adaptability in personal biomedical devices. The purpose of this study was to determine the viability of neural networks in predicting Freezing of Gait (FoG), a symptom of Parkinson's disease in which the patient's legs are suddenly rendered unable to move. More specifically, a class of neural networks known as layered recurrent networks (LRNs) was applied to an open- source FoG experimental dataset donated to the Machine Learning Repository of the University of California at Irvine. The independent variables in this experiment \u2014 the subject being tested, neural network architecture, and sampling of the majority classes \u2014 were each varied and compared against the performance of the neural network in predicting future FoG events. It was determined that single-layered recurrent networks are a viable method of predicting FoG events given the volume of the training data available, though results varied significantly between different patients. For the three patients tested, shank acceleration data was used to train networks with peak precision/recall values of 41.88%/47.12%, 89.05%/29.60%, and 57.19%/27.39% respectively. These values were obtained for networks optimized using detection theory rather than optimized for desired values of precision and recall. Furthermore, due to the nature of the experiments performed in this study, these values are representative of the lower-bound performance of layered recurrent networks trained to detect gait freezing. As such, these values may be improved through a variety of measures.

Description
With more than one third of Americans considered to be obese, obesity is a public health issue in the United States. While obesity is linked to and caused by a number of factors, sugar sweetened beverage (SSB) consumption is a major contributor to increased obesity rates. For the purposes of this paper, SSBs will include any beverage in which sugar is added. This includes juices that are not 100% fruit juice, coffee or tea drinks that are sugar sweetened, energy or sport drinks, and most commonly, soda. Excess sugar in the diet is substantially linked to obesity and negative health effects. SSBs represent the primary source of added sugar in the average American diet. Part I of this paper will discuss obesity as a public health problem and establish the link between consumption of SSBs and poor health effects. Part II will discuss the public policy instrument families and the strengths and weaknesses of each policy approach. Part III will identify current policies specifically focused on curbing SSB consumption. Each policy will be analyzed for efficacy based on available scientific research. Lastly, Part IV will propose new policy alternatives and ways to improve current policies. A final policy recommendation will be presented as an ideal roadmap for policy makers looking to address the link between SSB consumption and obesity.

Description
This project consists of two components: creating online math tutoring videos for University Academic Success Programs (UASP) and running a study to determine whether in-person tutoring sessions, in-person review sessions, or online tutoring videos are preferred by students seeking mathematical help. I created 22 tutoring videos based on a variety of topics where lower-division math students most commonly struggled. I then asked students who watched these videos or utilized services at the Downtown Phoenix Campus Student Success Center to complete a survey. I did statistical analysis on the data collected, and the results indicated that there may not be a specific type of tutoring service preferred by all students. Rather, there appears to be one group of students that prefers online services and another group of students that prefers in person services.

Based upon personal involvement from August 2010 to July 2014 as a Marine Option Midshipman within the ASU Naval Reserves Officer Training Corps (NROTC), being a student of leadership training within my degree plan, and gender difference research I conducted, this creative project addresses potential issues that reside within the ASU NROTC and the ways in which the program overall can be changed for the Marine Options in order to bring about proper success and organization. In order to officially become a Marine within the Unites States Marine Corps, it is necessary for Marine Option students to fulfill Officer Candidate School (OCS) at Quantico, Virginia. As the first female to go through OCS as a midshipman from the ASU NROTC, I found that there is an inadequate amount of preparation and training given in regards to the gender differences and what is to be expected for successful completion. I will offer a brief history regarding the NROTC across the Unites States and the ASU NROTC itself. These subjects will cover the program layouts as well as the leadership training that is required and provided within it and the ways in which this is conducted. I will then compare and contrast this to the leadership training given to me within my study of Leadership and Ethics regarding the transformational leadership, gender-based leadership, and coercive leadership. Finally, I end my thesis with a reflection of personal experiences taken away from these avenues and offer recommendations to better equip the ASU NROTC program in having successful retention and success of the female Marine Option midshipman.

Description
The recent emergence of DNA-based diagnostics increases the demand for rapid DNA sequencing technologies. One method to achieve this is to pass DNA through a nanopore, recording the trans-membrane current with a low-noise current amplifier. The project outlined in this report aims to demonstrate a design of a custom amplifier that offers a wider bandwidth than current designs while maintaining a low signal to noise ratio. The novel amplifier has been designed such that a multi-stage RF signal chain is integrated with an existing amplifier circuit to achieve DNA translocation. Both the existing amplifier circuit and the RF signal chain have produced outputs showing that the two amplifiers are functional and both low frequency signals and high frequency signals can be amplified with this comprehensive circuit design.

Description
A high voltage plasma arc can be created and sustained in air by subjecting the gases to an electric field with high voltage potential, causing ionization. The internal energy of the ionized gases can be transferred to corresponding pressure waves when the matter involved switches between the gaseous and plasma states. By pulse-width modulating a transformer driving signal, the transfer of internal electrical energy to resonating pressure waves may be controlled. Audio wave input to the driver signal can then be modulated into the carrier wave and be used to determine the width of each pulse in the plasma, thus reconstructing the audio signal as pressure, or sound waves, as the plasma arc switches on and off. The result will be the audio waveform resonating out of the plasma arc as audible sound, and thus creating a plasma loudspeaker. Theory of operation was tested through construction of a plasma arc speaker, and resultant audio playback was analyzed. This analysis confirmed accurate reproduction of audio signal in audible sound.
