Description
The Experimental Data Processing (EDP) software is a C++ GUI-based application to streamline the process of creating a model for structural systems based on experimental data. EDP is designed to process raw data, filter the data for noise and outliers, create a fitted model to describe that data, complete a probabilistic analysis to describe the variation between replicates of the experimental process, and analyze reliability of a structural system based on that model. In order to help design the EDP software to perform the full analysis, the probabilistic and regression modeling aspects of this analysis have been explored. The focus has been on creating and analyzing probabilistic models for the data, adding multivariate and nonparametric fits to raw data, and developing computational techniques that allow for these methods to be properly implemented within EDP. For creating a probabilistic model of replicate data, the normal, lognormal, gamma, Weibull, and generalized exponential distributions have been explored. Goodness-of-fit tests, including the chi-squared, Anderson-Darling, and Kolmogorov-Smirnoff tests, have been used in order to analyze the effectiveness of any of these probabilistic models in describing the variation of parameters between replicates of an experimental test. An example using Young's modulus data for a Kevlar-49 Swath stress-strain test was used in order to demonstrate how this analysis is performed within EDP. In order to implement the distributions, numerical solutions for the gamma, beta, and hypergeometric functions were implemented, along with an arbitrary precision library to store numbers that exceed the maximum size of double-precision floating point digits. To create a multivariate fit, the multilinear solution was created as the simplest solution to the multivariate regression problem. This solution was then extended to solve nonlinear problems that can be linearized into multiple separable terms. These problems were solved analytically with the closed-form solution for the multilinear regression, and then by using a QR decomposition to solve numerically while avoiding numerical instabilities associated with matrix inversion. For nonparametric regression, or smoothing, the loess method was developed as a robust technique for filtering noise while maintaining the general structure of the data points. The loess solution was created by addressing concerns associated with simpler smoothing methods, including the running mean, running line, and kernel smoothing techniques, and combining the ability of each of these methods to resolve those issues. The loess smoothing method involves weighting each point in a partition of the data set, and then adding either a line or a polynomial fit within that partition. Both linear and quadratic methods were applied to a carbon fiber compression test, showing that the quadratic model was more accurate but the linear model had a shape that was more effective for analyzing the experimental data. Finally, the EDP program itself was explored to consider its current functionalities for processing data, as described by shear tests on carbon fiber data, and the future functionalities to be developed. The probabilistic and raw data processing capabilities were demonstrated within EDP, and the multivariate and loess analysis was demonstrated using R. As the functionality and relevant considerations for these methods have been developed, the immediate goal is to finish implementing and integrating these additional features into a version of EDP that performs a full streamlined structural analysis on experimental data.

My name is Adriana Becerra and I am a student at the Walter Cronkite School of Journalism and Mass Communication at Arizona State University. In hoping to combine my two passions of journalism and film, for my Honors Undergraduate Thesis project I created my own film review website. My website is a complete review of the films that were nominated for the 2015 Oscars in the following categories: Best Picture, Animated Feature, Documentary Feature, Foreign Language, and Short Film Live Action. In all, I watched and reviewed a total of twenty-eight films based on acting, lighting, music, cinematography, costume/makeup/set design, writing, and visual effects. Over the course of nine months, I have watched, reviewed, and talked extensively about each film that I have reviewed. Though tedious at times, I thoroughly enjoyed completing my Undergraduate Thesis Project. I hope to continue critically looking at films, and possibly even incorporating film in my journalistic career.

Description
ASU's international student population has been growing exponentially in the last few years. Specifically, the fastest growing group has been international students from China. However, many of these students are arriving with inaccurate expectations of life at an American university. Furthermore, prospective students in China that have a desire to attend school in the U.S. are struggling to find a university that is affordable and respected. There is a huge opportunity for ASU to reach this market of students and increase their enrollment of international Chinese students. Our project aimed to create advertisements of ASU that target international Chinese students and their parents. The purpose of our project is to provide inspiration that ASU can utilize to create a professional marketing campaign to target this population of potential students.

Description
Since Dylan Roof, a white supremacist, shot and killed nine members of a black church in Charleston on June 17, 2015, Confederate symbols have stood at the center of much controversy across the United States. Although the Confederate battle flag remains the most obvious example, the debate took a particular form in Tennessee, centering on the image of General Nathan Bedford Forrest. Born in 1822 to a poor family, he left school early to work. Although his work in the slave trade made him a millionaire, his later participation in the massacre of over 300 black soldiers at Fort Pillow in 1864 during the Civil War and association with the Ku Klux Klan cemented his reputation as a violent racist. Yet, many white Tennesseans praised him as a hero and memorialized him. This thesis examines Nathan Bedford Forrest State Park in Benton County and Forrest Park, now Health Sciences Park, in Memphis to examine what characteristics denote a controversial memorial. Specifically, I focus on the physical form, the location, and the demographics of the area, investigating how these components work together to give rise to controversy or acceptance of the memorial's image. Physical representations greatly impact the ideas associated with the memorial while racial demographics affect whether or not Forrest's representation as a hero speaks true to modern interpretations and opinions.

Description
Despite regional peace agreements, billions of dollars in aid, and the United Nations’ largest peacekeeping mission in the world, conflict in the eastern Democratic Republic of the Congo persists. This paper explores criticisms made by political scientist Séverine Autesserre, who argues that three simplistic narratives revolving around conflict minerals as a cause, sexual abuse against women and girls as an outcome, and rebuilding central state control as the solution dominate how international interveners view the Congolese conflict. Autesserre further posits that conflict continues because peacebuilding efforts fail to address local dynamics. Using monitoring and evaluation reports of peacebuilding projects in the eastern Congo, primarily from the U.S. Agency for International Development, this paper examines three questions: Do aid agencies have any local peacebuilding projects? If so, do these projects reinforce the dominant narratives? And lastly, do these projects view conflict as a continuum that must be managed through process-oriented objectives, or as a binary phenomenon requiring events-oriented objectives, such as elections? The analysis is based on 10 total reports gathered online, the majority of which are from USAID. Due to a lack of publicly available data and M&E reports on Congo peacebuilding, this collection does not represent a random sample and is not being used to make statistically significant conclusions. Nevertheless, the M&E reports provide a window into how the “rubber meets the road,” so to speak, in terms of how USAID and others view the role of their peacebuilding programs and how to assess programmatic success.
These reports reveal there are certainly some local peacebuilding programs and they do appear to view conflict as a continuum requiring process-oriented goals, such as creating local community mediation organizations. In terms of Autesserre’s three dominant narratives, the results are more mixed. This assortment of seemingly contradictory findings does not mean Autesserre’s arguments are invalid. The USAID Congo Country Strategy document unlocks this apparent contradiction as it explicitly acknowledges Autesserre’s criticisms and appears to move toward finding more nuanced approaches to the conflict. However, at times it still emphasizes the same dominant narratives and state-to-state level approaches. This paper, therefore, concludes that USAID, and potentially others, are in a state of transition between entrenched and evolving narratives. The discord in these evaluations highlights the internal crisis peacebuilders in the Congo are currently facing as they reassess their narratives. In keeping with the self-improving nature of M&E, hopefully these international interveners can move through their narrative transition in an efficient manner, so that they can remain a supportive peacebuilding partner to the Congolese people.

Description
The international disaster-relief organization Doctors without Borders (MSF) is a dynamic geopolitical actor. Using a systematic literature review of academic journal articles and first person accounts by doctors from the field, the geopolitical role of MSF was analyzed. This search returned a wide range of articles many of which referenced the term “humanitarian space”. MSF utilizes humanitarian space to accomplish their medical work and witnessing actions in disaster areas. MSF’s geopolitical role stems from many of the central characteristics of the organization, but the process of creating humanitarian space engages them differently at both a global and a local level. Case studies of MSF’s work in Haiti and Rwanda reveal the interplay between global and local levels. Humanitarian space at the global level is a more imagined space. At this level, MSF relies on their practice of “témoignage” or testifying as their primary method for creating this space. At the local level, MSF focuses on their humanitarian patient-care to earn themselves space uninhibited by other power-wielding groups. These two levels work as a see-saw so that when the humanitarian space occupied by MSF is threatened at one level they can lean on their space at other in order to continue providing the best services possible. During the Rwandan genocide, MSF’s on the ground was work was limited to a single hospital in a single city and to compensate, they worked hard at the global level to bring attention to the violent situation in the country. This balance switched in the aftermath of the Haiti earthquake of 2010 during which massive space for humanitarian action on the ground, made advocating at a local level unnecessary. Analysis of MSF from a political geography perspective opens up new avenues of examining the many interdisciplinary characteristics of an organization as wide-reaching as Doctors without Borders.

Description
The wettability of powders is an important characteristic for both industry and academia and is often described by the powder’s contact angle with a certain liquid. While there exist many ways to measure contact angle, it is a portion of the powder technology field that is not fully understood and requires more investigation and research. This study investigates two methods for measuring contact angle, the sessile drop method and the Washburn method, and looks to compare results to determine which method offers the most reliable data in terms of accuracy and repeatability. Two powders - microcrystalline cellulose and aluminum oxide - and three liquids - water, 50 cSt silicone oil, and 350 cSt silicone oil - were used to study the differences between the two measurement techniques as well as the effects of varying fluid viscosity on the measurements. It was found that the sessile drop method proved to be an ineffective method for measuring contact angle when liquid penetration into the powder occurred, as the contact angle changed while the drop penetrated. Initial results showed the contact angle for silicone oil on the powders to be greater than 90°, indicating nonwetting of the surface which was inconsistent with observations. The results from the Washburn method align better with other values in similar studies, but more study is needed to confirm the results gathered in this research.

In a world where tweets, texts, posts, likes and favorites are a part of our daily lives, it's hard not to believe everything we see. Every little detail of one's personal life is easily shared with the world with the click of a button. And because of this, the beauty standards that society has created is jumping from the pages of magazines and TV shows to apps such as Instagram and Facebook. The majority of social media users are young teens and adults, but the popularity of these apps is rising among kids as young as five years old as well. These are some of the most impressionable years of one's life. So, by seeing these standards that qualify someone as "beautiful," individuals are likely to strive toward these standards. And while some may seem impossible to attain, individuals are willing to go to extreme lengths to get there. Qualities like the "thigh gap" are slowly becoming more popular, and are putting individuals at risk. In a country where the ideal woman is skinny, and most of the celebrities and models showcase these nearly impossible standards, it's hard not to fall into the trap. With the addition of editing software and filters to already existing social media applications, the ability to edit and enhance photos is in the hands of the user. Photos can be edited so dramatically different from the original that what we're seeing doesn't even exist. This project explores the false reality that social media is creating and the negative effects it has on young girls and women. It also offers a solution to the problem.

Description
Musical interpretation is challenging when one's goal is to evoke an emotional response from an audience. In order to develop a well-informed interpretation of Mozart's Fantasia in D minor K. 397, a study was conducted on the historical background of the piece and various performances by well-regarded performers. Fantasias are written works, but improvisatory by nature. Mozart's fantasias were influenced by C. P. E. Bach's, which included sudden changes in emotion. An Emil Gilels performance provided a classically trained approach, while Mitsuko Uchida's performance provided an emotional approach. Colin Tilney and John Irving performances elucidated the sound of the instruments that Mozart would have been composing with. Altogether, the research culminated in an interpretation of the D minor Fantasia that endeavored to capture the essence of fantasy, improvisation and emotion.
