Description
One of the grand challenges of engineering is to provide access to clean water because it is predicted that by 2025 more than two thirds of the world’s population will face severe water shortages. To combat this global issue, our lab focuses on creating a novel composite membrane to recover potable water from waste. For use as the water-selective component in this membrane design Linde Type A zeolites were synthesized for optimal size without the use of a template. Current template-free synthesis of zeolite LTA produces particles that are too large for our application therefore the particle size was reduced in this study to reduce fouling of the membrane while also investigating the nanoparticle synthesis mechanisms. The time and temperature of the reaction and the aging of the precursor gel were systematically modified and observed to determine the optimal conditions for producing the particles. Scanning electron microscopy, x-ray diffraction, and energy dispersive x-ray analysis were used for characterization. Sub-micron sized particles were synthesized at 2 weeks aging time at -8°C with an average size of 0.6 micrometers, a size suitable for our membrane. There is a limit to the posterity and uniformity of particles produced from modifying the reaction time and temperature. All results follow general crystallization theory. Longer aging produced smaller particles, consistent with nucleation theory. Spinodal decomposition is predicted to affect nucleation clustering during aging due to the temperature scheme. Efforts will be made to shorten the effective aging time and these particles will eventually be incorporated into our mixed matrix osmosis membrane.

Description
This study investigates the use and perception of communications efforts among 197 animal-related and human services nonprofit organizations. Several facets of nonprofit communication such as traditional communication usage, social media adoption and usage, and the overall perception of the organizations' communications efforts were examined using a survey and Form 990 analysis. More in-depth analysis was conducted on the participating organizations' Facebook and Twitter accounts as well. After analyzing this data, the study found significant differences in how these two types of nonprofit organizations conduct their communications efforts. Animal-related organizations were much more active and saw higher levels of engagement on Facebook than human services organizations; however, there were no differences in how both types of organizations used Twitter. This study also found that human services organizations are more likely to have full-time or part-time staff members in charge of their communications, while animal-related organizations were more likely to assign this responsibility to a volunteer. These findings contribute valuable insight into how different types of nonprofit organizations are communicating with their stakeholders.

Description
A combined examination of the Charlie Hebdo attacks on January 7, 2015 and the November 13, 2015 attacks in Paris yields a social media movement that evolved within the 10 months between the attacks, a comparison between these terrorist attacks and those of September 11, 2001 and parallels between American First Amendment principles and France’s free expression laws.
The Charlie Hebdo attacks fueled an online debate over freedom of expression and religion, whereas the purpose of social media evolved into a humanitarian one following the November 13 attacks in Paris. This research looks into the individual evolutions of the related hashtags that surfaced in 2015, including #JeSuisCharlie (and its opposites, such as #JeNeSuisPasCharlie), #DonDuSang, #PorteOuverte and #RechercheParis, among others. Another research point was with the September 11 attacks—with the 9/11 attacks against the United States, few to no channels were available for the kind of immediate discussions and support seen after the Paris attacks. After spending time in Paris during the spring 2015 semester and researching the aftermath of the Charlie Hebdo attacks and the history of the publication, the conclusion rests on the idea that the online discussions perpetuated by both supporters and dissenters of the magazine contribute to a more robust, open democracy supported by these social media platforms.
A portion of this thesis also delves into the parallels and differences between the American First Amendment and the French free speech laws—all of which pertain to the Charlie Hebdo content and the online responses to the 2015 Paris attacks.
The interviews conducted include a French art history professor at the Sorbonne University in Paris, two creators of the “Je Suis Charlie” Facebook page, an American journalist living in Paris who covered the Charlie Hebdo attack and who was present during the November attacks, and a Muslim-American doctor in Phoenix who founded the American Islamic Forum for Democracy. The ideas surrounding free speech, the value of art such as that found within the pages of Charlie Hebdo, the media’s treatment of religion, traditional democratic freedoms and ties to social media revolutions are all components of this research thesis.

Description
This paper examines the relationship between feminism and social media and evaluates the ability of social media to function as an effective platform for the advancement of feminism's objectives. In the decades before social media became an integral part of culture, the popularity of feminism deteriorated and feminist voices were unsure that it could be revived or popularized again. However, in recent years, women have used social media as a mechanism to communicate and disseminate feminist ideas. The birth of what is called "hashtag feminism" has been a fundamental shift in the way feminism is done and advocated for in modern culture. In light of this dramatic shift in venue for feminist conversations, academic feminists are asking a series of pertinent questions: Is social media good for feminism and the achievement of feminist objectives? What, if anything, has feminism compromised in order to fit into 140 characters or fewer? This paper argues that social media has provided a platform for feminists to share their stories, which has aided in the building of feminist constituencies. This is the most important work of feminism, because it is making society more receptive to feminist principles and ideas, transforming our culture into one that can accept and fight for feminism's objectives. This paper will examine a series of case studies in which social media has hosted feminist conversations. It will analyze the impact of this social media as a venue for feminist narratives and evaluate the use of social media as a feminist platform in the movement to achieve feminism's objectives.

Description
Many individuals are not following healthy lifestyles as evidenced by the high obesity rates and poor physical activity levels. Many do not know how to eat healthy and exercise effectively, especially given busy schedules and no time to cook or go to the gym. However, people do spend a significant amount of time on their mobile device using social media. This outlet can potentially be used to inspire and teach individuals how to cook healthy simple meals, or find motivation to get off the couch for some exercise. In this study, strategies were identified that would increase the comments, likes, and followers of the investigator's Instagrams, which were designed to motivate followers to live a healthier lifestyle. Initially, 462 posts were assessed retrospectively to determine how the number of likes and comments were influenced by hashtags, category of posts (nutrition, fitness, or inspiration), and/or type of app, PicPlayPost, Instaframe, and the updated Instagram. These results were used in a 1-month prospective study to increase likes and followers to the investigator's Instagrams. In the retrospective study, it was determined that hashtags influenced the number of comments and likes across the categories and that the PicPlayPost app increased the likes in all categories. Hence, for the prospective study, the investigator wrote 1 nutrition and 1 fitness post daily for 28 days using a minimum of 15 hashtags per post. In addition, 3 nutrition posts and 3 fitness posts per week used the PicPlayPost app. This posting strategy increased the number of likes per post by 100%, and the number of followers increased from 369 to 1082 in one month. Interestingly, the nutrition posts received 27% more likes than the fitness posts, and the PicPlayPost app increased comments by 134%. In conclusion, the use of hashtags, PicPlayPost, and Instaframe apps increased the likes and comments on social media. These strategies may increase audience's attention on a certain topic and be used to improve individuals' lifestyles.

Description
The study of the mechanical behavior of nanocrystalline metals using microelectromechanical systems (MEMS) devices lies at the intersection of nanotechnology, mechanical engineering and material science. The extremely small grains that make up nanocrystalline metals lead to higher strength but lower ductility as compared to bulk metals. Effects of strain-rate dependence on the mechanical behavior of nanocrystalline metals are explored. Knowing the strain rate dependence of mechanical properties would enable optimization of material selection for different applications and lead to lighter structural components and enhanced sustainability.

Description
Sports teams are an integral part of a city. They attract revenue to the area around the stadium and they also give a city a sense of pride. The aim of this study was to determine what makes a team successful in the area of attendance using four factors (Bernthal & Graham; Jensen; Kim, Trail & Magnusen; Edensor & Millington; Clowes & Tapp; Greenhalgh & Greenwell; Denaux & Yalcin; Paul & Weinbach & Robbins; Levin & McDonald; Lee & Kang; Drayer; L'Etang; McDonald & Rascher; Armstrong; Ross): the history of the team, the location and population of the city where the team plays, the social media following of the team and the promotional giveaways the team uses to attract fans. Using these four factors, a comparison was made among the Arizona teams and the top performing team in attendance in the respective leagues during the 2013 season. The Arizona Diamondbacks are compared with the Los Angeles Dodgers. The Diamondbacks were not as equipped as the Dodgers in any of the categories. There is a more storied history for the Dodgers, the Dodgers play in Los Angeles - a significantly larger city that Phoenix, where the Arizona Diamondbacks play, they use social media more frequently and more effectively, and they offer more promotional giveaways than the Diamondbacks. The Phoenix Suns are compared to the Chicago Bulls. The Suns history competes with the Bulls, but they lack in the other three categories. The Bulls have a better location in Chicago, their stadium is located in the downtown area; they have a massive social media following and their promotional giveaways are more substantial. The Phoenix Coyotes are compared to the Chicago Blackhawks. The Blackhawks exceeded in all of the categories, while the Coyotes were poor performers in each of the four factors. The Blackhawks have a storied history, they share a stadium with the Bulls, they have a great social media following and they give promotional items away 30 of the 41 home games. The overall recommendations for the teams are to win, in order to help build their locations and make it fun to be near the downtown area, to use social media effectively and engage with their audience, and finally to provide more promotional giveaways to attract people to the games.

Description
Social media is an industry that is rapidly growing and is affecting our society, our health, and our social environments. Emerging research suggests that Social Media has been linked to Poor Body Image, Cyberbullying, Depression, Internet Addiction, and Loneliness among other things. This paper looks at the research and discusses the designer's role in the matter. Is it possible that poor design is the cause of these problems? Can design solve these problems? Are there ethical standards that digital product designers in particular can abide by?
