Description
This research contributes to emergent body of knowledge regarding the understanding of relationship between visual elements and E-learning outcomes. Visual images and texts are the main visual elements within the study.
A literature review was conducted on E-learning situations, and a discussion on the role of visual elements in E-learning. Data collection was also conducted by way of a test, which randomly placed participants into three groups and assigned them to three different E-learning courses. The texts for the three courses were the same font, but the first course had text only, the second course had text and "bad" images, and the third one had text and "good" images. Every time participants finished a short course, they were requested to do a short quiz based on what they had learned. In addition, every participant needed to do a survey based on his or her E-learning experience. Research data was finally collected through the test scores and surveys.
Key findings of this research are: (1) The combination of text and "good" image materials in E-learning can greatly enhance the learning outcomes; (2) the "good" images in learning materials can add to the value of the text content as well as improve the satisfactory level of learners in E-learning; (3) "bad" images do not enhance E-learning outcomes; and (4) E-learners will spend a longer time to complete learning materials containing images, no matter how good or "bad" the images are.

Description
Contemporary cities are physical and virtual. This thesis describes the findings of a mixed-methods study concerning visual images of the city in the urban Northeast of the United States. I ground these approaches in existing literature concerning digital media, visual narrative, genre ecology, urban planning, and virtual places. The first part of the study analyzes the results of a survey in which 150 people responded to questions about social media use and the relationships between image type and the functions of social media in urban contexts. The second part of the study analyzes the results of coding one year of visual images tweeted by @CambMA, the municipal Twitter feed for the City of Cambridge, Massachusetts. These approaches required the development of new tools for analyzing visual communication and genre moves in specific media contexts. My research suggests that specific image types are suited for specific media functions in the context of visual communication in virtual urban environments and that some image types are especially effective in capturing and expressing the city. These findings provide potential strategies for municipal social media channels to consider in terms of how they communicate with their audiences.

Abstract
On a daily basis I am bombarded with images in every walk of life. I encounter images crossing my path constantly through media such as the internet, television, magazines, radio, social media, even in the grocery store line on screens intended to capture our attention. As I drive down the roadways, I am invaded by images that at times can be distracting with their dazzling displays, attempting to get our attention and get us to consume their product or service or understand a historical meaning. In this dissertation I intend on looking at murals and two social studies textbooks to focus types of media; then construct an argument about how these media impact social studies curricula in the communities in which they are located taking into consideration race, social class, language, location, and culture. The intent is to critically analyze traditional curricula and curricula found in public pedagogy in communities located on the borderlands. I also asked local high school-aged students, teachers, artists, and activists from both sides of the border analyze the images through photo elicitation and traditional interviews. Students were interviewed with a focus on interpreted meanings of images presented. Teachers and artists were interviewed to discover their intended meanings as displayed through their production and circulation of intended meanings via lessons and the images they select or create. Activists were interviewed to discover local history, images, and history of the educational space where the artwork and schools are located. I used these data to create an argument as to how these forms of media impacts school curricula in the areas on both sides of the United States/Mexico border. The study was conducted in border cities El Paso, Texas and Juarez, Chihuahua. The ultimate goal was to look at how academics and curricula developers can use this information to decolonize curricula in the field of curricula studies. Moreover, this information can be used to create decolonized ideologies in curricula that can be used at the school sites to promote diversity and social justice for students in their schooling experience.

Description
Fueled by fear in the post-9/11 United States, American intelligence agencies conduct dragnet data collection on global communication. Despite the intention of surveillance as preventative counter-terrorism action, the default search and seizure of global communication poses a threat to our constitutional rights and individual autonomy. This is the case especially for people who may be thought of as in opposition to our current political climate, such as immigrants, people of color, women, people practicing non-western religions, people living outside of the United States, activists, persons engaging in political dissent, and people with intersecting identities. Throughout the Fall and Spring semesters, I have done research, conducted visual experiments and designed exploratory projects in order to more thoroughly identify the issue and explore the ways in which visual communication design can aid in the conversation surrounding global surveillance. It was the intention of my fourth year social issue projects to explore the role of visual communication design in the dialogue surrounding surveillance, principally focusing on the responsibility visual communication design has in spreading ideas about how to globally subvert surveillance until governments disclose information about their unconstitutional actions or until whistleblowers do it for them. My final project, the fourth year social issue exhibit, focuses on how improving our personal password habits can help us gain agency in digital spaces. Using the randomness of rolling a dice to generate entropy can help us generate stronger passwords in order to secure sensitive information online. Using design as a method of communication, my fourth year social issue exhibit shared information about how encrypted passwords can act as the first line of defense in protecting ourselves from invasive data collection and malicious internet activity.

Description
"Bringing-before-the-eyes": Visuality and Audience in Greek Rhetoric examines how Greek rhetorical theories are understood through the lens of visuality and the ways in which orators accounted for audience knowledges and expectations in the creation of rhetorical texts and performances. Through a close reading of Greek rhetorical texts from the classical period, I develop three heuristics for analyzing the ways in which rhetoricians invite and encourage visualized images through rhetorical practice.
By exploring (1) language cues that orators use to signal visualization, (2) the ways in which shared cultural memories and ideas allow orators to call upon standardized images, and (3) the influence of stylistic choices and audience emotions related to the vividness of rhetorical images, I argue that it is possible to analyze the ways in which classical Greek orators understood and employed visual elements in their rhetorical performances. I then conduct an analysis of the visual aspects of Demosthenes' On the Embassy using these heuristics to demonstrate the ways in which these three aspects of visuality are intertwined and contribute to a greater understanding of the relationship between the verbal and the visual in rhetorical theory.
My findings indicate that Greek orators readily identified the influence of visual ways of knowing on rhetorical theory and presented early hypotheses of the ways in which sense perceptions affect social practice. This project complicates the ways in which rhetorical theory is categorized. Rather than considering visual rhetoric as a distinct field from traditional, verbal text-based rhetorical studies, this project explores the ways in which visual and verbal modes of thinking are interconnected in Greek rhetorical theory. By bridging these two areas of rhetorical study and arguing that verbal rhetoric can instantiate internalized, visual phenomena for audiences, the dichotomy of verbal and visual is problematized. By focusing on the rhetorical theory of classical Greece, this project also invites future research into the ways in which dominant, Western historic and contemporary systems of epistemology are influenced by the co-mingling of verbal and visual in classical Greek philosophy and education.

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
Invasive species are non-native plants or animals that harm the environment, economy, and even human health. These species are introduced to new environments where they have no natural predators or competitors to keep them in check. As a result, they grow and reproduce quickly, outcompeting and displacing native species. Invasive species can also damage crops, infrastructure, and property, leading to significant economic losses. Moreover, some invasive species can carry diseases that can affect human health. As the leading cause of biodiversity loss according to the IUCN Red List, controlling and preventing the spread of invasive species is critical to protecting biodiversity and maintaining a healthy environment.
