Description
Sexual and social signals have long been thought to play an important role in speciation and diversity; hence, investigations of intraspecific communication may lead to important insights regarding key processes of evolution. Though we have learned much about the control, function, and evolution of animal communication by studying several very common signal types, investigating rare classes of signals may provide new information about how and why animals communicate. My dissertation research focused on rapid physiological color change, a rare signal-type used by relatively few taxa. To answer longstanding questions about this rare class of signals, I employed novel methods to measure rapid color change signals of male veiled chameleons Chamaeleo calyptratus in real-time as seen by the intended conspecific receivers, as well as the associated behaviors of signalers and receivers. In the context of agonistic male-male interactions, I found that the brightness achieved by individual males and the speed of color change were the best predictors of aggression and fighting ability. Conversely, I found that rapid skin darkening serves as a signal of submission for male chameleons, reducing aggression from winners when displayed by losers. Additionally, my research revealed that the timing of maximum skin brightness and speed of brightening were the best predictors of maximum bite force and circulating testosterone levels, respectively. Together, these results indicated that different aspects of color change can communicate information about contest strategy, physiology, and performance ability. Lastly, when I experimentally manipulated the external appearance of chameleons, I found that "dishonestly" signaling individuals (i.e. those whose behavior did not match their manipulated color) received higher aggression from unpainted opponents. The increased aggression received by dishonest signalers suggests that social costs play an important role in maintaining the honesty of rapid color change signals in veiled chameleons. Though the color change abilities of chameleons have interested humans since the time of Aristotle, little was previously known about the signal content of such changes. Documenting the behavioral contexts and information content of these signals has provided an important first step in understanding the current function, underlying control mechanisms, and evolutionary origins of this rare signal type.

Description
In this dissertation, organizational whistleblowing is guided by the methods for writing Creative Nonfiction. That is to say, a true story is told in a compelling and creative, easy to read manner, so that a broader audience, both academic and non-academic alike, can understand the stories told. For this project, analytic concepts such as antecedents, organizational culture, resistance and dissidence, social support, and ethics are embedded in the narrative text. In this piece, the author tells the story of a whistleblowing process, from beginning to end. Using the techniques advised by Gutkind (2012) questions and directions for research and analytic insight are integrated with the actual scenes of the whistleblowing account. The consequences of whistleblowing are explored, including loss of status, social isolation, and a variety of negative ramifications. In order to increase confidentiality in the dissertation, pseudonyms and adapted names and locations have been used to focus on the nature of the whistleblowing experience rather than the specific story. The author ends the dissertation with reflection on whistleblowing through the insight gathered from his firsthand account, suggesting advice for future whistleblowers and directions for future organizational research on whistleblowing.

Description
More than simply a source of income, work has become a central source of identity (Beder, 2000; Ciulla, 2000; Clair, McConnell, Bell, Hackbarth & Mathes, 2008; Muirhead, 2004). motivating scholars to engage in a plethora of studies examining the impact of work as a way of defining ourselves, ranging from identification with the organization (Scott, Corman, & Cheney, 1998) to the influence of work on non-work lives (Kirby, Wieland & McBride, 2006). And yet, in such volatile political and economic times, individual's identities as worker are threatened, spurring questions about how to decenter the meaning of work in our lives (Rushkoff, 2011). Despite young people's roles as organizational members, few communication scholars have considered the organizational experiences of youth as a productive area for research and theory (for exception see Myers & Sadaghiani, 2010). I adopt a discursive approach to unpack the multiple ways that discourses, at interpersonal, organizational and social levels, impact and influence youths' identity construction process (Ashcraft & Mumby, 2004; Fairhust & Putnam, 2004). I empirically demonstrate how discourses of work operate simultaneously at multiple levels, interacting and overlapping to position youth as workers. Analysis is based on interviews with youth, ages 12 to 21, participating in a popular national nonprofit organization that serves over four million youth each year. In addition to 49 one-on-one formal interviews, I observed 50 hours of a worker preparation program, which serves as an important context for priming participants and situating our conversations about work. Practically, this project illustrates the influence of organizations to mediate the relationship between discourse and identity. Methodologically, I further clarify discursive analysis as a method by explicitly articulating a concrete framework by which to identify micro-, meso-, and macro-levels of discourse. I also present a qualitative instrument for interviewing youth. Theoretically, this research offers an innovative and necessary expansion to the scope of organizational research by highlighting youth as current and future workers, pointing to the ways they are already engaged in work-life negotiation practices and considering how their micro-discursive practices serve to decenter the organization and make work and family meaningful.

Description
This dissertation examined sojourner adjustment success utilizing a unique method for collecting and analyzing the perceptions and sense making of the sojourner participants. Although previous research studies in this area have mostly relied on quantitative survey designs and researcher-generated models, this study relied on in-depth, participant-driven, qualitative interviews that were semi-structured using a software-assisted method called Interpretive Structural Modeling (ISM). Through this dissertation research, study abroad students (sojourners) had the opportunity to reflect on their sojourn experience, share their adjustment stories, and identify factors that were personally relevant to their success. This study broke new ground while building on the vast body of work in cross-cultural and sojourner adjustment. Sojourners were asked to provide their perspectives on the relationships among those factors reported in the literature that are commonly believed to influence successful adjustment. This allowed me to connect existing literature on the subject with the lived experience of the sojourner participants. This dissertation sought to answer two research questions. First, what factors do participants identify as being keys to the success of their sojourn? Second, what relationships do participants perceive among the factors contributing to successful sojourner adjustment? This dissertation found that language proficiency played a key role in their adjustment and openness was the factor most selected by participants in their explanation of a successful sojourn. Additionally, participant profiles and influence structure summaries provided evidence of the relationships participants saw among success factors in their lived experiences. In terms of preparing sojourners for going abroad, analysis of the composite structure revealed what could be prioritized in pre-departure training for impending sojourners. Themes emerged which provide insight into the commonalities of the sojourner experience despite differences in one's program or personality. This dissertation also explained additional success factors participants identified (e.g., ability to manage language fatigue, creation of connections with other travelers) that were not initially provided to them. Finally, suggestions for study abroad students/coordinators, researchers, and employers are provided.

Description
The purpose of this study was to measure the effect of gendered communication on women's behavioral intentions regarding nonprofit and for-profit entrepreneurship. Women represent half of the U.S. workforce, but only about one third of all American entrepreneurs are women. Feminists have argued that because entrepreneurship is largely understood as a masculine activity, women — who are predominantly socialized to espouse a feminine gender role — are less likely to become entrepreneurs. Previous scholarship and the particular theoretical lens of social feminism suggest that communication about entrepreneurship that is congruent with a feminine gender role would lead to the recruitment of a greater number of women entrepreneurs. Findings of the current study, however, suggested the opposite, providing support for poststructuralist feminist theory. Women who viewed a feminine entrepreneurship recruiting brochure about entrepreneurship reported themselves to be more feminine and less likely to report intentions to become entrepreneurs than women who viewed a masculine entrepreneurship recruiting brochure. These findings suggested that feminine communication may prime women to think of themselves as feminine, which may then lead them to view themselves as not masculine enough to be entrepreneurs. The applications of these findings stretch beyond engaging more women in entrepreneurship and also extend to scholarship that investigates gender's effects on women's pursuit of other masculine careers, including those in science, technology, engineering, and mathematics. Until the larger discourse on entrepreneurship changes to be inclusive of femininity, it is unlikely that strategies that feminize entrepreneurial activity in controlled situations will have an effect on changing the patterns of women's entrepreneurial intentions.

Description
This dissertation examines collaborative inquiry as a form of graduate mentoring. To investigate this issue, I analyze the research and writing process of a team of five multilingual graduate students and their mentor as they collaboratively design, implement, and report a study based in their local writing program over the course of two years. Through a qualitative activity analysis of team meetings, participant interviews, and the team’s written drafts and email correspondence, I investigate the ways in which self-sponsored, team-based collaborative research and writing supports participants’ learning and development of a professional identity.
Key findings show that unanticipated obstacles in the research context present participants with “real-world” dilemmas that call forth disciplinary alignments, reinforce existing disciplinary practices, and, most importantly, generate new practices altogether. An example of this process is reflected in the research team's frequent need to adjust their research design as a result of constraints within the research environment. The team's ability to pivot in response to such constraints encouraged individual members to view the research enterprise as dynamic and fluid, leading ultimately to a heightened sense of agency and stronger awareness of the rhetorical challenges and opportunities posed by empirical research. Similarly, participants’ demonstrated an ability to recognize and resolve tensions stemming from competing demands on their time and attention during the course of their graduate study. Actively constructing resonances across various domains of their graduate worlds—coursework, teaching, and non-curricular research and professionalization activities—served to clarify purposes and increase motivation.
An additional aspect of this study is the way graduate students leverage their language resources in the collaborative process. This dissertation extends the disciplinary conversation by investigating ways in which language resources function as rhetorical tools within the research context. This focus on language, in concert with collaboration and rhetorical stances to inquiry, challenges persistent views of authorship, apprenticeship, and language norms, while simultaneously lending insight into how graduate students invent new ways of participating in their professional worlds.

Description
The death of a parent or sibling for youth under age 18 is life-altering and necessitates support and opportunities for expressing grief. Scholarship from psychology and medical disciplines often equates youthful grieving as a disease to be cured rather than a natural process to be experienced. Stage-based grief models explain adults coping with loss of loved ones by working through a series of discrete phases mostly tied to deficit-based emotions such as anger or depression. Progressive grief models have been emerging throughout the past 20 years in response to stage-based models; however these models tend to highlight deficit-based emotions and are applied to youth as afterthoughts. Thus, there is a noticeable absence of research exploring positive or strength-based emotions in adolescent grief from a communicative, youth-centered perspective. A communicative approach to exploring adolescent grief narratives offers a practical yet pliable theoretical lens for interpreting meaning from mourning. Using qualitative methods, I conducted full participant research as a volunteer with Comfort Zone Camp, a national organization sponsoring weekend-long grief camps for youth. I engaged in participant observation while volunteering to explore the communicative processes of 26 grieving adolescents and also conducted post-camp follow-up interviews with youth, parents, and adult volunteers. Analysis was based on 192 field work hours, 11 interview hours, artifacts, and camp documents. Findings of the dissertation indicate grieving adolescents use communicative processes, including sharing emotional pieces, co-authoring loss, and naming hurt, to perform a range of emotions. Along with deficit-based emotions, grieving adolescents perform strength-based emotions, including confidence, forgiveness, happiness, deservingness, hope, gratitude, resilience, love, and compassion. Evidence also supports that grieving campers performed compassion individually and in groups. Theoretically, this dissertation expands on existing grief theory by demonstrating that adolescents communicate strength-based emotions in grief, captured visually in the Concert of Emotions model. This study expands on compassion theory by exploring implications of collective compassion expressions. Specifically, this dissertation offers the co-performing sub-process to account for collective compassion extending past compassion models that focus on individual expressions. Practically, this research yields new understanding into how grieving adolescents constitute themselves as compassionate, helpful contributors as they face loss.

ABSTRACT
This study sought to inform the curriculum of crew resource management (CRM) for multi-pilot flight deck operations. The CRM curriculum requires continued reexamination to ensure safe flight in the changing demographic of flight decks in the US. The study calls attention to the CRM curriculum’s insufficient inclusion of robust training components to address intercultural communication skills and conflict management strategies.
Utilizing a phenomenological approach, the study examined the communicative experiences of African American female military and airline transport pilots on the flight deck and within the aviation industry. Co-cultural theory was used as a theoretical framework to investigate these co-researcher’s (pilots) experiences. A parallel goal of the investigation was to better understand raced and gendered communication as they occur in this specific context—the flight deck of US airlines and military aircraft.
The researcher conducted in-depth semi-structured interviews and shadowed two co-researchers (pilots) for a period of days and built a relationship with them over the course of one year. Eight years of preparation working in the airline industry situated the researcher for this study. The researcher collected stories and interviews during this time immersed in industry. The data collected offers initial insights into the experiences of non-dominant group members in this unique organizational environment.
The study’s findings are reported in the form of a creative
arrative nonfiction essay. This effort was twofold: (1) the narrative served to generate a record of experiences for continued examination and future research and (2) created useful data and information sets accessible to expert and non-expert audiences alike.
The data supports rationalization as a co-cultural communication strategy, a recent expansion of the theory. Data also suggests that another strategy—strategic alliance building—may be useful in expanding the scope of co-cultural theory. The proposed assertive assimilation orientation identifies the intentional construct of alliances and warrants further investigation.

Description
Despite the various driver assistance systems and electronics, the threat to life of driver, passengers and other people on the road still persists. With the growth in technology, the use of in-vehicle devices with a plethora of buttons and features is increasing resulting in increased distraction. Recently, speech recognition has emerged as an alternative to distraction and has the potential to be beneficial. However, considering the fact that automotive environment is dynamic and noisy in nature, distraction may not arise from the manual interaction, but due to the cognitive load. Hence, speech recognition certainly cannot be a reliable mode of communication.
The thesis is focused on proposing a simultaneous multimodal approach for designing interface between driver and vehicle with a goal to enable the driver to be more attentive to the driving tasks and spend less time fiddling with distractive tasks. By analyzing the human-human multimodal interaction techniques, new modes have been identified and experimented, especially suitable for the automotive context. The identified modes are touch, speech, graphics, voice-tip and text-tip. The multiple modes are intended to work collectively to make the interaction more intuitive and natural. In order to obtain a minimalist user-centered design for the center stack, various design principles such as 80/20 rule, contour bias, affordance, flexibility-usability trade-off etc. have been implemented on the prototypes. The prototype was developed using the Dragon software development kit on android platform for speech recognition.
In the present study, the driver behavior was investigated in an experiment conducted on the DriveSafety driving simulator DS-600s. Twelve volunteers drove the simulator under two conditions: (1) accessing the center stack applications using touch only and (2) accessing the applications using speech with offered text-tip. The duration for which user looked away from the road (eyes-off-road) was measured manually for each scenario. Comparison of results proved that eyes-off-road time is less for the second scenario. The minimalist design with 8-10 icons per screen proved to be effective as all the readings were within the driver distraction recommendations (eyes-off-road time < 2sec per screen) defined by NHTSA.

The purpose of this study was to examine the utility of the Extended Parallel Process Model (EPPM) in guiding message design for a new health context, reducing meat consumption. The experiment was a posttest only design with a comparison and a control group. Message design was informed by the EPPM and contained threat and efficacy components. Participants (Americans ages 25-44 who eat meat approximately once a day) were randomly assigned to view a high threat/ high efficacy video, a high threat/ low efficacy video, or to be in a control group. Dependent variables were danger control outcomes (i.e., attitudes, intentions, and behavior) and fear control outcomes (i.e., perceived manipulative intent, message derogation, and defensive avoidance). Outcomes were assessed at an immediate posttest (Time 1) and at a one-week follow up (Time 2). There were 373 participants at Time 1 and 153 participants at Time 2. The data did not fully fit either the EPPM or the additive model; both videos were equally persuasive and resulted in greater message acceptance (attitude change, behavioral intention, and behavior) than the control group. Because the high threat/ low efficacy group was more persuasive than the control group, the data more closely fit the additive model. Fear control outcomes did not differ between the two video groups. Overall, the study demonstrated the effectiveness of using the EPPM to guide video message design in a new health context, reducing meat consumption. The results supported the EPPM prediction that a high-threat high-efficacy message would result in message acceptance, but support was not found for the necessity of an efficacy component for message acceptance. These findings can be used to guide new or existing health campaigns that seek to improve public health outcomes, including reducing the incidence of heart disease, cancer, diabetes, and obesity.
