This thesis focuses on the ways in which theoretical models based in rhetorical studies can be used to enhance both the understanding and the practice of communication. In particular, my project shows that rhetoric and communication theory can provide a foundation for improving communication practice. <p>Every communicative act takes place within a context, as Lloyd F. Bitzer established. This same understanding of the centrality of situation to communicative effectiveness permeates the work of several other theorists whose work is discussed in this thesis, among them Wayne C. Booth, Kenneth Burke, George L. Dillon, Barnett Baskerville, and Donald Schon. <p>Using Bitzers conception of the rhetorical situation as the theoretical focus, two main concerns are addressed in the thesis: the relationship between rhetoric and the practice of technical communication, and the integration of theory and practice as the foundation of rhetorical understanding. The first three chapters present a series of theoretical models, and the practical use of this theory is tested by an exercise in writing a public speaking handbook for engineering undergraduates (presented as Chapter Four of the thesis). The audience for this handbook is specific and the purpose is narrow to give advice on preparing, practising, and presenting design presentations to professors and clients. This experiment is then followed by a reflection on the writing process and some conclusions about the relationship between rhetorical theory and communicative practice.<p> The key result of this research and case study is a deepened understanding of how rhetoric operates or how it should be studied. As a rhetorician, I found it discouraging even at times humiliating to discover how much difficulty I had in adapting my discourse to a specific audience. This research makes clear that an understanding of theory without a solid grounding in practice is insufficient for rhetorical mastery. While my original goal was to demonstrate the usefulness of theory to improving practice, this thesis shows as well the extent to which rhetorical theory also depends on an understanding of the demands and constraints of actual practice.

This qualitative study provided insight into the phenomenon of newcomers in social networking, in particular, to understand what role specific Facebook features play in motivating content sharing and contribution among newcomers. Research indicated that the first several months or years of social networking site (SNS) membership are the most crucial in terms of indicating long-term participation and commitment to the SNS. Long-term participation is specifically manifested through interactions with peers who are members of the same website and through interactivity such as content sharing and contribution. A number of quantitative studies have focused on motivations for user contribution in social networking sites, but inconsistent findings demonstrated the need for a qualitative approach to understand the user experience more clearly. The purpose of the study was to understand how users are motivated to engage in Facebook from their perspective as newcomers and to distill the significance of social media interface features as an enabler of community sharing. Insight into this phenomenon further demonstrates how specific actions on Facebook such as tagging, posting on profiles, and chatting help foster a sense of belonging and socialization among the sample group. The phenomenon is studied through interviews with a distinct group of Facebook members - women who are aged 40 and older in the Science, Engineering, and Technology (SET) industry who are also newcomers to Facebook. The lived experiences of these respondents were explored through open-ended questions, related to their own use of the said social networking site. Semi-structured interviews allowed respondents to be candid and comprehensive in their answers. Five themes developed related to the motivations for Facebook use from the lived experiences of the women interviewed. The themes were (a) social connection, (b) visual artifact sharing, (c) shared identity, (d) social investigation and (e) education. These themes were consistent with findings of other studies, but the personal accounts of these women revealed how they perceived use of various Facebook features improved the quality and depth of their interpersonal relationships. The findings of this study have implications for designers, developers, and users of computer-mediated communications and technologies. By understanding the value of various features to users of all ages, communications inhibitors such as distance and culture can be overcome with effective design and innovation.

Situating makerspaces as an extension of post-industrial economies, and sites where technical communication and craftivism take place, this dissertation builds on critiques of makerspaces as hobbyist spaces that privilege digital electronics, populated mostly by white men. To do so, this dissertation analyzes who participates in feminist makerspaces, how “makers” describe their work and their experiences, and the roles of rhetoric and technical communication within feminist makerspaces. Building on prior studies of maker communities, this research follows a mixed methods approach and an iterative methodology, including online survey, site studies, interviews, and on-site automated survey to collect user data via kiosk. The online survey asked participants to describe makerspaces they’ve visited, their experiences visiting makerspaces, their work, and themselves. Follow-up interviews conducted with three survey participants addressed times participants felt unwelcome or out of place in a makerspace. Additionally, site studies consisted of visiting and observing two Midwestern makerspaces, both of which partnered with public libraries. This dissertation argues that makerspaces need to do a better job of welcoming guests and new members and actively hosting social events, rather than passively marketing workshops focused on specific technologies. Although people are becoming more familiar with makerspaces, regardless of gender and other aspects of identity, participants describe social anxieties about entering new spaces and unfamiliar communities as common barriers to entry, even before encountering issues based on gender, race, and other aspects of identity. If makerspaces (and “maker” communities more broadly) aim to be more inclusive and equitable, then actively welcoming people in general is a necessary baseline. As such, this dissertation draws from rhetorical theory to suggest ways that makerspaces can improve their hospitality and technical communication practices.

abstract: With 285-million blind and visually impaired worldwide, and 25.5 million in the United States, federally funded universities should be at the forefront when designing accessible websites for the blind community. Fifty percent of the university homepages discussed in my thesis failed accessibility checker tests because alternative text was not provided in the alt-attribute for numerous images, making them inaccessible to blind users. The images which failed included logos, photographs of people, and images with text. Understanding image content and context in relation to the webpage is important for writing alternative text that is useful, yet writers interpret and define the content and context of images differently or not at all. Not all universities follow legal guidelines of using alternative text for online images nor implements best practices of analyzing images prior to describing them within the context of the webpage. When an image used in a webpage is designed only to be seen by sighted users and not to be seen by screen reader software, then that image is not comparably accessible to a blind user, as Section 508 mandates. / Dissertation/Thesis / Masters Thesis Technical Communication 2018

This thesis addresses the need to claim creativity as an essential component to our technical communication curricula as we prepare students for what their managers want. While many technical communication programs at universities across the country have recognized a need to teach skills beyond 'writing technically,' few, if any, have addressed or 'claimed' a concept such as creativity that helps build these skills. I argue that creativity is what managers are looking for and what technical communication programs are already implementing. Claiming this concept will help us further define a discipline that is becoming much richer and help students develop an understanding of what they will be expected to do. Furthermore, this thesis examines a creative process whereby technical communicators can learn and practice creative abilities. Ultimately, the present study examines four pedagogical theories to consider for the implementation of creativity into the technical communication curricula.

In this thesis I argue that technical communication as an academic curricular entity has struggled to define itself as either a humanities or scientific discipline. I argue that this crisis of identity is due to a larger, institutional flaw first identified by the science studies scholar Bruno Latour as the problem of the "modern constitution." Latour's argument, often referred to as Actor-Network Theory (ANT), suggests that the epistemological arguments about scientific certainty are built on a contradiction. In viewing the problem of technical communication's disciplinarity through the lens of ANT, I argue that technical communication can never be productive if it seeks to locate itself within any of the institutional camps of the modern university. Rather, I contend that technical communication is a strong example of a nonmodern discipline, and that its identity crisis can be utilized to take one step towards rewriting the institutional debate over scientific certainty.
