Extraordinary medical advances have led to significant reductions in the burden of infectious diseases in humans. However, infectious diseases still account for more than 13 million annual deaths. This large burden is partly due to some pathogens having found suitable conditions to emerge and spread in denser and more connected host populations, and others having evolved to escape the pressures imposed by the rampant use of antimicrobials. It is then critical to improve our understanding of how diseases spread in these modern landscapes, characterized by new host population structures and socio-economic environments, as well as containment measures such as the deployment of drugs. Thus, the motivation of this dissertation is two-fold. First, we study, using both data-driven and modeling approaches, the the spread of infectious diseases in urban areas. As a case study, we use confirmed-cases data on sexually transmitted diseases (STDs) in the United States to assess the conduciveness of population size of urban areas and their socio-economic characteristics as predictors of STD incidence. We find that the scaling of STD incidence in cities is superlinear, and that the percent of African-Americans residing in cities largely determines these statistical patterns. Since disparities in access to health care are often exacerbated in urban areas, within this project we also develop two modeling frameworks to study the effect of health care disparities on epidemic outcomes. Discrepant results between the two approaches indicate that knowledge of the shape of the recovery period distribution, not just its mean and variance, is key for assessing the epidemiological impact of inequalities. The second project proposes to study, from a modeling perspective, the spread of drug resistance in human populations featuring vital dynamics, stochasticity and contact structure. We derive effective treatment regimes that minimize both the overall disease burden and the spread of resistance. Additionally, targeted treatment in structured host populations may lead to higher levels of drug resistance, and if drug-resistant strains are compensated, they can spread widely even when the wild-type strain is below its epidemic threshold.

Description
The People's Republic of China's inexorable ascendancy has become an epochal event in international landscape, accentuated by its triple national ceremonies of global significance: 2008 Beijing Olympic Games, 2009 Beijing Military Parade, and 2010 Shanghai World Expo. At a momentous juncture when the PRC endeavored to project a new national identity to the outside world, these ceremonial occasions constitute a high-stake communicative opportunity for the Chinese government and a fruitful set of discursive artifacts for symbolic deconstruction and rhetorical interpretation. To unravel these ceremonial spectacles, a public memory approach, with its versatile potencies indexical of a nation's interpretive system of social meaning, its normative framework of ideological model, and its past-present-future interrelationships, is contextually, conceptually, and analytically diagnostic of a rising China's sociopolitical constellations. Thus employing public memory as a conceptual-methodological matrix, my dissertation focuses on the prominent texts in these ceremonies, excavates their historico-memorial invocation and sociocultural persuasion, and plumbs their discursive agenda, rhetorical operation, and sociopolitical implication. I argue that the Chinese government deliberately and forcefully strove for three interrelated communicative objectives at these three ceremonies--re-imaging, re-asserting, and re-anchoring its national identity as an ancient, emergent superpower. Yet in contemporary Chinese context, its discursive (con)quest to recast its leadership as a historically continuous, culturally orthodox, and ideologically legitimate regime has always been compromised by its mythologized historical representation and hegemonic rhetorical reconfiguration, countervailed by its political and ideological fragility, and contested by domestic and global publics. Besides its contributions to the current conversation on the PRC's ceremonial phenomena, discursive formations, and communicative dynamics, this dissertation further offers its diagnosis and prognostication of this projected leading country in the 21st century.

Description
Public mass shootings occur at a rate in the U.S. that is higher than any other developed country. These event initiate wide spread media attention. The media attention these events achieve have shown to impact the public behavior (e.g., increased firearm sales). However, the impact public mass shootings have on firearm storage and carry habits of the public is not well understood. Using data collected from the Transportation Security Administration, this study examines how mass shootings have led to moral panics occurring within the U.S. through the examination of the firearm carrying habits among the population immediately following mass shootings. The results indicate that loaded firearms with rounds in the chamber detected by the TSA have significantly increased since 2012. Further, firearms detected immediately following a public mass shooting had a higher proportion of firearms loaded with a round in the chamber relative to 7 days prior to the shooting. Moreover, the increase in proportions of firearms found loaded with a round in the chamber exponentially decays as days past the initial shooting, these events occur at a higher rate than the decay rate can normalize these occurrences. I conclude that in the wake of these shootings a moral panic ensues that is partially responsible for the change in the general public’s arming configuration habits. Further research is needed in to determine the impact on crime, and public health related issues due to this change in the public’s firearm carrying habits.

Description
INTRODUCTION: This thesis delves into how PR-media relations evolved in the past 20 years (since 1997). It discusses several aspects of media relations, such as relationships, old and new media relations tools, pitching and predictions about the future of media relations. LITERATURE REVIEW: A review of previous literature on media relations guided this research. Past research explained stigmas about the relationship between public relations professionals and journalists, how pitching has evolved, social media's role in modern day media relations and the dynamic between earned and owned media. METHODOLOGY: The research involved a mixed method approach with qualitative and quantitative methods. First, in-depth interviews were conducted with both journalists and public relations professionals who work in Arizona. These interviews were conducted either in-person or over the phone. Second, two in-depth interviews were conducted over the phone with a public relations professional who worked at Intel for over 20 years for a case study. Finally, a survey was distributed to public relations professionals in Arizona via email and through social media websites (Facebook and Twitter) to provide insight on the media relations tactics they have recently utilized, as well as their use of social media. There were also five follow-up interviews conducted with survey respondents. FINDINGS: After conducting these three methods of research, the qualitative (quotes) and quantitative (survey) data were analyzed to provide detailed opinions about media relations including: the relationships between public relations professionals and the media, the use of old and new media relations tools, what an effective pitch looks like, the use of social media, comparisons between less and more experienced PR professionals, and predictions on the future of media relations. DISCUSSION: The findings from this research led to several conclusions regarding media relations such as: the importance of maintaining a trusting and respectful relationship, traditional tools' place in modern day media relations, email's dominance as a media relations tool, the hesitation by PR professionals to use social media as a communication tool with journalists, more experienced PR professionals' lack of hesitation to use social media as a communication tool with journalists, and the prediction that relationships will remain key in media relations despite the changes in media relations tools themselves. CONCLUSION: Based on all of the findings from this research, it was concluded that media relations has evolved to keep up with the changing media landscape, however, traditional tools and practices remain relevant and essential to media relations.

Description
Nonprofits often struggle in fully implementing a successful social media strategy. These organizations neglect to create and maintain relationships with stakeholders, engage their audience, and build brand awareness in an online setting. As social media has essentially become one of the largest sources of information dissemination and one of the most populated platforms in the online world, a nonprofit's online presence has become increasingly important. Through a 22-day content analysis and 43-question survey that was distributed to the general public on Twitter and Facebook, this paper looks comprehensively into the elements and tactics used by Make-A-Wish, Halo and ALS Association. Based off of the research findings from this study, important aspects of these nonprofits' online strategy will be identified and analyzed.

Description
This project is a strategic online media proposal for aBloom Salon. In order to provide the salon with a successful social media proposal, there must be an analysis of the current situation informed by secondary and primary research. aBloom in Latin means transformation; this salon specializes in holistic beauty. At this salon all the products are organic, natural and raw. They use a non-toxic ammonia-free color line and have a Raw Beauty Bar where clients can create all-natural custom products. This proposal aims to increase aBloom Salon's brand awareness in the most effective way possible. The project started by analyzing the salon's website, Facebook page and Instagram content and following-up with recommendations for improvement. In addition to that analysis, research was conducted on current clients to gage their social media habits and purpose for using social media. Salon owner, Alejandra Martinez, currently averages 20 to 30 clients a week and said she would like to increase to 25 to 35 clients a week. Martinez was promoting her salon through her website, word-of-mouth, Facebook, Yelp, Instagram and cross-promoting efforts with likeminded businesses.

Description
This study looks to answer whether or not citizens have reason to believe the publicity statements from state government officials when speaking about gun-control laws during the time surrounding mass shootings. Citizens in America see the same, consistent pattern that politicians use mass shootings for, known as "The Shooting Cycle." Here, we will research whether or not these politicians are continuing to keep the same voting pattern that they have had in the past, in terms of gun control. This case study uses quantitative research to discover that almost all state representative and senators have consistent voting patterns when it comes to gun control legislation, regardless of time distances around mass shootings. We will then seek out seek out public statements and relevant periodicals and media clips in order to determine whether or not these voting patterns align with the public's perception of a politician's stance on gun control. It also uses qualitative research to discover that publicity from senators and representatives that support gun rights have more consistency in their public statements than those who are either inconsistent or consistently vote for gun control legislation. This study creates opportunities for new research in voting patterns and political transparency on state officials and the significant effects of mass shootings on public opinions and public statements from state officials.

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.

This researcher set out to determine whether small businesses can achieve considerable business success by utilizing social media as a public relations tool to create a brand image. There is a substantial breadth of research regarding the social media successes of large companies, but the same is not true for small businesses. This researcher aims to add to the existing pool of literature dealing with small businesses and creating social media success. First, relevant literature was examined to determine the state of the small business landscape online and to identify best practices for social media. Then the researcher analyzed three published case studies that detailed social media campaigns from three different small businesses. The researcher used the information obtained in the literature review and case study analysis to create a comprehensive social media strategy for Crosswim, a small business based in Tempe, Arizona. The culmination of this research showed that small businesses can indeed create success and brand equity by implementing a strategic social media plan. It was uncovered that social media gives small business owners the tools to create a strategy that works best for them in terms of their business and in terms of the time the owners can devote to monitoring social media.
