Description
Scholars have identified the mass media plays a crucial role in the dissemination of terror messages. Since the attacks of September 11th, 2001, much attention has been paid to terrorism in the global television landscape. More recently, the discourse surrounding acts of terror has changed, in part due to the people behind the attacks. This study seeks to understand how global television news broadcasts frame acts of terror based on two current threats: the individual terrorist (the Lone Wolf) and the organized group (the Islamic State). Using the theoretical framework of Entman’s framing theory and Altheide’s (1987) notion of a global drama, this research identifies the ways global news organizations frame acts of terror both visually and verbally based on the classification of the attacker. Using content analysis methodology, this study analyzed six terror attacks that took place between November, 2015 and December, 2016. Three of these attacks were classified as “Lone Wolves” and three were carried out by the terrorist organization called the Islamic State. This study looked at 562 stories on six global news channels and examined 9,479 images. Through a comparative analysis, three American and three International news channels were examined. It was discovered global news networks contain visual differences in framing, but similarities in verbal framing. Although it was expected to find vast differences in global news’ framing of acts of terror, this study finds a homogenization of the television news narrative following terrorist attacks. This study builds on existing research and suggests a global script for covering acts of terror that has several implications from a theoretical and practical standpoint. Findings indicate global coverage of Islamic State attacks employ and “Us vs. Them” frame, while Lone Wolf attacks are framed as “Us vs. Us”, a new frame presented in this study. The results advance the literature focused on framing theory, comparative journalism research and global television news coverage of terrorism. As terrorism has garnered extensive media attention, understanding the ways that global news frames terrorism has vast implications.

Description
Although smaller and more local elections could have implications more dramatic to an individual than larger district-, state-, and nation-wide elections do, very few citizens vote in them. Moreover, citizens are limited in procuring further information on candidates, issues, and the overall election when there are fewer sources of such information across various mediums. While existing literature on political communication and voter participation does not yet extend far enough to sufficiently address the most local aspects of media effects on elections, the political science field’s dominating frameworks would suggest that an increase in news media, social media, and ground mobilization tactics would increase civic engagement and voter participation. My research, which focuses on hyperlocal elections, both supports andrefutes certain elements of that suggestion. Based on surveys of potential voters in a university’s student government election and a school board election, interviews with two student government presidential candidates, and an analysis of social media engagement, my research compares three mass media platforms and two elections to characterize the effects of media on hyperlocal elections—that certain tactics have drastically different results on different populations. My research expands the body of media and politics knowledge to include hyperlocal elections, suggesting that civic engagement on the local levels require increased further study.

Description
Mass media has played a central role in the construction of "illegal" immigration as a crisis, despite demographic trends suggesting otherwise, resulting in public concern and extreme policies. Additional coverage by local news has brought the issue closer to home, leading state legislatures to action. This project analyzes trends in a 10 year period in local news articles and state-level legislation about undocumented immigration in Arizona and Alabama. The representation of immigration as a threat has consequences for the lives of immigrants and what it means to be an American.

Description
Forensic science has commanded the spotlight in mainstream media, both fact-based and fictional. Popular fictional shows, like CSI: Crime Scene Investigation, give unrealistic scenarios of criminal proceedings by forensic scientists and investigators. From inaccurate timetables to blurred job responsibilities, fictional media has spread misconceptions of the industry. Fictional shows depict unrealistic relationships between the investigators and the scientists. Documentary crime shows and movies, while based in fact, are often oversimplified for entertainment purposes. Public safety officials and the news media are often at odds. The media yearns to release case details as quickly as possible, while officials attempt to keep investigations closed to the public to minimize public harm. This research takes a unique approach to study the impact media entities have on the public's perception of Arizona's criminal just system, and how the system has responded as the public's expectations have been altered. Evidence collecting procedures have changed, along with the sheer volume of evidence processed on a daily basis at crime labs around the state. Courtroom procedures have also changed, as juries now expect physical evidence to be presented in every case. Mass media must do a better job of accurately portraying criminal investigative techniques in order to better educate the public, and to produce a better informed jury pool with reasonable expectations concerning criminal evidence. Higher education also has a significant role to play in both making the public aware of the power and limitations of forensic science, and in preparing future generations of forensic scientists.

Description
Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

Description
Lesbian, gay, bisexual, transgender and queer (LGBTQ+) individuals experience a variety of types of representation, particularly in media outlets. While the quantity of such representations is steadily increasing, research must continue to examine the content of representations as they become available. This examination is important as much of society is determined by discourses presented in media outlets. Further, media often produces and reproduces dominant narratives about minority groups. Television is one arena where individuals come to learn about themselves and others. Particularly, the sitcom genre can be useful for figuring out how to deal with real-world issues in a humorous and entertaining way. However, the humor of sitcom does not exclude it from the meaning-making and identity-formation systems present in television and media, more broadly. Thus, this study investigates the discourses surrounding LGBTQ+ representation in the Canadian sitcom Schitt’s Creek through critical and rhetorical discursive analyses while also applying principles of queer theory throughout. Results indicate while Schitt’s Creek does many things well in terms of its representation of LGBTQ+ individuals, problematic stereotypes still often remain. In other words, Schitt’s Creek breaks from typical LGBTQ+ representation found in sitcoms, but often still embodies dominant cultural narratives used to degrade, restrict, and punish LGBTQ+ individuals. This is particularly evident as one examines the ways Schitt’s Creek often falls into heteronormative standards and continually polices the sexual nature of LGBTQ+ individuals to display a safe and comfortable version of homosexuality. Therefore, Schitt’s Creek may often and unknowingly reinforce the heteronormative hegemonies it seeks to break from.

Description
There has been a vast increase in applications of Unmanned Aerial Vehicles (UAVs) in civilian domains. To operate in the civilian airspace, a UAV must be able to sense and avoid both static and moving obstacles for flight safety. While indoor and low-altitude environments are mainly occupied by static obstacles, risks in space of higher altitude primarily come from moving obstacles such as other aircraft or flying vehicles in the airspace. Therefore, the ability to avoid moving obstacles becomes a necessity
for Unmanned Aerial Vehicles.
Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate
these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.

Description
This study tests the hypothesis and assumption of much critical scholarship that the discourse of mass media news transmits prejudicial ideologies to news consumers, influencing the way they think about social justice issues and non-dominant groups in American society, including immigrants, women, and African-Americans. Taking off from the motivations and premises of Critical Discourse Analysis concerning language, power, and ideology, this study aims to extend that paradigm in several ways by applying the analytic techniques of cognitive and critical linguistics to uncover implicit representations in biased discourse. This study also goes beyond previous work by examining the reader comments on media texts to understand how the media’s discourse was received and interpreted, with a focus on the covert transmission of ideological messages. The results reveal how ideologies of prejudice are communicated implicitly through media discourse and how readers’ own ideologies influence that process, as evidenced by their comments. As a study in Critical Discourse Analysis, this study uncovers abuses of power impacting social justice – in this case, the power of writing for the mass media to mold American minds, and therefore influence Americans’ behavior, including elections. Specific news articles from the American networks CNN and Fox were chosen on each of two topics for their relevance to current sociopolitical issues of prejudice and social justice: the US Supreme Court June 2018 decision to uphold the Trump administration “travel ban” and the January 2019 Gillette advertisement, considered controversial for its seemingly feminist criticism of male behavior.

Description
Ever since Cleveland-based disc jockey Alan Freed coined the term "rock 'n' roll" in the early 1950s, the genre has gone through various mass media and digital changes over the decades. These changes took place on the radio, television and internet. Each platform had its own unique ways of increasing the popularity of rock artists as well as the genre itself. Although the radio is not as popular today as it was in the 20th century, it helped pave the way for today’s most popular music streaming platforms like Spotify and Apple Music. The television gave artists a chance to be seen nationally or even worldwide. Music videos and live performances allowed viewers to see past artists’ voices and witness their energy. The internet gave bands and artists multiple platforms to share their content and connect with fans. In 2020, having a social media presence became essential for artists wanting to maintain a successful music career during the COVID-19 pandemic. Rock music most likely would not be what it is today if it had not gone through these various changes.
