Show moreThis dissertation studies, analyzes, and experimentally demonstrates the innovative use of interference phenomenon in the field of opto-electronic information processing and optical communications. A number of optical systems using interferometric techniques both in the optical and the electronic domains has been demonstrated in the filed of signal transmission and processing, optical metrology, defense, and physical sensors. Specifically it has been shown that the interference of waves in the form of holography can be exploited to realize a novel optical scanner called Code Multiplexed Optical Scanner (C-MOS). The C-MOS features large aperture, wide scan angles, 3-D beam control, no moving parts, and high beam scanning resolution. A C-MOS based free space optical transceiver for bi-directional communication has also been experimentally demonstrated. For high speed, large bandwidth, and high frequency operation, an optically implemented reconfigurable RF transversal filter design is presented that implements wide range of filtering algorithms. A number of techniques using heterodyne interferometry via acousto-optic device for optical path length measurements have been described. Finally, a whole new class of interferometric sensors for optical metrology and sensing applications is presented. A non-traditional interferometric output signal processing scheme has been developed. Applications include, for example, temperature sensors for harsh environments for a wide temperature range from room temperature to 1000 degree C.

Show moreFor many faculty, teaching online represents a new instructional delivery method, requiring the development of new teaching skills. This exploratory investigation builds upon Rogers' (2003) Diffusion of Innovations theory and communication channels to describe the influence of faculty discussions on their perceptions and decisions about teaching and learning. A sequential explanatory mixed-methods research design, using both sociometric and phenomenological methodologies, guided the exploration of faculty personal network exposure models and social learning opportunities. The study utilized online survey and open-ended interview instruments for the investigation. Faculty from several colleges at the University of Central Florida voluntarily completed the survey instrument identifying with whom, how, and why they discuss teaching online, including the influence of these discussions. In-depth interviews offered internal descriptions of their personal networks. Survey results established baseline data for demographic and future comparisons and identified concerns, issues, and trends unique to synchronous and asynchronous Internet-based faculty development and support needs. Phenomenological data produced the emergent categories and themes used to investigate and explain faculty's communication channel usage and social learning experiences. Similarities between diffusion and knowledge research findings and participants reflected more conformity than anticipated. Differences in communication channel and learning style preferences and usage and faculty's 24/7 work life needs, present challenges to administrators and educators responsible for providing development and support systems.

This was accomplished by administering the Communication Attitude Test for Adults Who Stutter (BigCAT; Vanryckeghem and Brutten, 2018), a subtest of the Behavior Assessment Battery (BAB; Vanryckeghem and Brutten, 2018). The BigCAT was administered to 33 PWS and a modified version was administered to their LPs via Qualtrics, an online survey software system. Between-group total score comparison revealed no significant difference in total scores, and a low-medium score correlation was evidenced. Within both groups, participants age and gender did not have a significant effect on total scores. The perception of stuttering severity was found to significantly influence BigCAT scores within each group. No differential effect of duration of relationship on score agreement was found to exist. A high Cronbach Alpha coefficient was obtained for both test forms. Between-group item score comparison revealed that only answers on two out of the 34 items differed significantly. They were related to frequency of speech disruption and avoidance of persons, places or situations. Item 24 had a perfect correlation between the two groups and relates to common behaviors PWS exhibit in trying to attain more fluency. Overall, the findings of this study show that LPs of PWS have a general understanding of the impact stuttering has on their partner who stutters' communication attitude.

Show moreIn the United States, people are encouraged and even coerced by social forces to behave and interact according to rigid social mores that tend to privilege individuals from a specific gender, racial, and class backgrounds. As many theorists have stated, sexual, gender, and racial minorities navigate their lives experiencing oppression at different levels and at the intersections of different systems of inequality. The marginal social location of these identities often results in people re-defining the social meanings through which they construct their social lives. Although much research has been devoted to investigating the different ways in which people resist the dominant social order, research on polyamory is still highly unexplored. According to the studied population, polyamory is a form of ethical non-monogamy that promotes egalitarian relationships among all parties involved. According to Dr. Mimi Shippers, "poly sexualities offers an opportunity to reorient [...] gender and race relations" (2016:4). In this study, I collected data from nine semi-structured interviews that shine light upon how people in polyamorous relationships engage in the reorientation of gender relations. By looking at reported communication strategies between polyamorous individuals, this study found that the social location of marginalized sexual and gender identities fosters a sense of solidarity through which people redefine the meaning in their interactions as they inform people's identity. Nevertheless, these dynamics result in the resistance of some aspects of the dominant social order and the reproduction of others.

Children with disabilities are at high risk for several forms of maltreatment, including abuse and neglect (Ammerman, Hersen, Van Hasselt, Lubetsky, & Sieck, 1994; Sullivan & Knutson, 1998b), and children with hearing and communication disorders comprise a substantial portion of children at risk (e.g., Sullivan & Knutson, 2000).

Show moreChildren with disabilities are at high risk for several forms of maltreatment, including abuse and neglect (Ammerman, Hersen, Van Hasselt, Lubetsky, & Sieck, 1994; Sullivan & Knutson, 1998b), and children with hearing and communication disorders comprise a substantial portion of children at risk (e.g., Sullivan & Knutson, 2000). For example, some literature investigating the parenting practices of parents raising children and adolescents with hearing and communication disorders suggests that these parents have a tendency to use physically harsh discipline practices (Knutson, Johnson, & Sullivan, 2004; Sullivan & Knutson, 1998b). Further, high prevalence rates of emotional and behavioral problems are documented in these youth (e.g., Greenberg & Kusché, 1989; Hindley, 1997; Prizant, Audet, Burke, & Hummel, 1990). Despite these findings, a limited amount of research focuses on understanding factors related to these undesired outcomes. Therefore, this study investigates the relationships among dimensions of parents' psychological functioning and parent-child interactive processes in a culturally diverse, national sample of families raising children and adolescents with hearing and communication disorders. Results suggest that parents' stress, depression, and anxiety as well as parent-child communication and involvement are important correlates of discipline practices and subsequent child behavior in families raising children and adolescents with hearing and communication disorders. Additionally, psychological aggression and parents' depression are highly predictive factors in the use of corporal punishment. Also, psychological aggression and parenting stress are highly predictive of reported youth behavior problems. The information gained from this investigation may provide direction for assessment and therapeutic intervention with parents of children and adolescents who have hearing and communication disorders.

Show moreSocial media aids communication among users worldwide. However, a notable gap exist among social media users, healthcare professionals utilizing social media in the work place. While the concept of harnessing social media as a professional tool is not novel, healthcare professionals have yet to embrace the practice as standard workflow. This study identifies factors influencing clinicians' behavioral intent to adopt social media for patient engagement and communication. A new framework, the Healthcare Social Media Adoption Framework (HSMA), guided this mixed-method approach to assess 7 factors identified by theory and literature as adoption influencers. A custom, web-based survey collected data from 60 full-time, pediatric clinicians (47 quantitative) at the case institution (a pediatric hospital). Additionally, individual interviews of 6 participants provided their prospective on using social media for patient communications and engagement. Results: Privacy concerns were the only statically significant factor; with an inverse relationship to positive adoption intent, indicating higher privacy concerns influence lower behavioral intent to adopt social media for patient engagement and communication. The qualitative analysis revealed privacy concerns encompass two themes, personal privacy for patient and providers (boundaries), and cybersecurity. The qualitative inputs also uncovered perceived unprofessionalism as a new factor influencing clinician adoption. The implications for these findings indicate a need for both healthcare organizations and healthcare regulators to establish cyber-security defenses for security and use protocols for privacy to aid the diffusion and adoption acceptance of social media use by pediatric healthcare professionals. This research has contributed in four areas: 1) fill a knowledge gap by identifying new factors that influence the behavioral intent of pediatric clinicians to adopt social media; 2) confirm/reject behavioral intent influences found in the literature; 3) formulated a new HSMA framework that measures functional, cognitive, and social aspects of social media adoption; and 4) prioritizes policies and global standard focus.

Show moreThis study queried collegiate level instructors of public speaking asking if there was a gender based difference in their attitudes and beliefs about stuttering. The survey examined for relationships between instructor level of education and: sources of knowledge, knowledge of causation and, amount of knowledge about stuttering. Communication literature searches indicated there were few, if any, studies which specifically addressed the knowledge levels, sources of knowledge and causation information for stuttering. Stuttering occurs in approximately 1% of the worldwide population so it is reasonable to expect that most collegiate level instructors would have individuals who stutter presenting in their classrooms. A Qualtrics survey, presented the Public Opinion Survey of Human Attributes (-) Stuttering, to participants across the United States who were members of the Basic Course in communication list serv or who were subscribed to CRTNET. A total of 134 individuals responded to the survey. The majority of respondents were native English speakers, with a small number speaking Spanish as a second language. Respondents represented thirty six of the fifty United States with 113 respondents reporting they actively were teaching the basic course in public speaking. Statistical analyses indicated there were no significant differences between master and doctoral level educated instructors in their: sources of knowledge; information on causation of stuttering, and; amount of knowledge about people who stutter. There were no significant differences between instructor gender and attitudes about stuttering, and beliefs about people who stutter. Findings underscored the limited amount of information which this sample of public speaking instructors possessed regarding the causation of stuttering as only 37.7% of respondents selected genetics as an underlying factor in the occurrence of stuttering. The majority of instructors reported some information to none about people who have a stuttering disorder. They indicated their knowledge was acquired through personal experiences, school, and to a lesser degree, print media.

Show moreClothing is a powerful nonverbal communicative tool and form of self-expression that provides others with clues about our personality, mood, education, culture, financial status, and social ranking, amongst numerous other impression cues. Research shows that physical appearance plays a prominent role in the formation of initial judgments and is significant in shaping a person's overall impression on others (Richmond, McCroskey, (&) Payne, 1991). The present study sought to quantitatively explore the effect that different styles of dress have on initial judgments formed about women in workplace settings. Using expectancy violation theory, the study investigates workplace gender bias and whether or not certain styles of women's dress garner different initial reactions. Results showed that models in feminine attire are perceived to be lower in ratings of dominance and expertise, and models in more masculine attire are perceived to be lower in ratings of kindness and friendliness.

Show morePresently, there is a national focus on the industry-benefitting skills developed through undergraduate education. The purpose of this study is to examine the effectiveness of an experiential learning course on building three ability-based transferable skills: communication, emotional intelligence, and professional qualities. These skills have been determined to be important components to the skill set of graduates intending to enter any career, including one within the hospitality industry. Results from an examination of three related instruments led to conclusions that an experiential learning course positively impacts self-perceived skill development among the three aforementioned skills as well as perception of overall performance. In addition, it was determined that experiential learning courses benefitted interns irrespective of self-reported learning style preference and that such courses may aid in narrowing the perceived gap between intern and employer perceptions of intern skill levels and thereby prepare graduates with increasing success for societal productivity.

Show moreOnline collaborations are more prevalent in society due to electronic communication allowing students and professionals to communicate with each other, without needing to spend time or money traveling. The lack of visual cues in electronic communication means writing styles primarily set the tone of a message. A group member's gender can affect his or her writing style and what he or she assumes about the message. The differing writing styles and potential gender bias can cause misunderstandings, which delay projects and sometimes lead to ostracizing a group member. The gender composition of an online collaboration, therefore, can have a positive or negative effect on a project. This study helps technical communicators understand how to manage online collaborations effectively to produce a successful project. The study explains how the effects of gender composition on a project are influenced by electronic communication, gender roles, and online collaborations. Society-imposed gender roles include differing writing styles for each gender causing gender bias in both writing and reading electronic messages. Group members, monitors, and project managers must take care in managing online collaborations due to the differences in each gender's communication style, and differences in gender roles and expectations for multinational online collaborations. The study shows mixed-gender collaborations have increased chances of misunderstandings because of the differing communication styles of each gender compared to same-gender collaborations. However, the advantages of mixed-gender collaborations outweigh the disadvantages due to the variety of ideas, motivations, and expectations. Technical communicators understanding how all the major topics relate together to influence a collaboration are better able to manage an online collaboration and reduce the chances of misunderstandings to create a successful project.

Show moreSeventeenth century England was forced to come to terms with events such as the Civil War and the regicide of King Charles I, in the midst of contending with the cultural changes brought upon by print culture, the effects of which appeared throughout all aspects of English society. These changes helped form a relationship between print and oral culture, one of negotiation among the producers and regulators of work and the society consuming the works. The discussion of this negotiation has led to varying conclusions concerning the true impact of printed materials on English society and culture, all of which tend to see the relationship in one of two ways: print's undeniable and unprecedented influence on culture, or its function as supplement to oral and visual communication. The latter conclusion helped form the foundation of this study, which aims to further understand the negotiation between print and English society. The close analysis of recurring themes of the supernatural, specifically prophecy, witchcraft, regicide, and the natural world, will show unmistakable similarities between popular entertainment and written works. Through the examination of these themes, this thesis will illustrate the extent to which common imagery and wording appeared in newsbooks and what this says about oral communication and culture in early modern England.

Show moreInformation fluency refers to the ability to recognize information needs and to gather, evaluate, and communicate information appropriately. In this study, I treat "information fluency" as both an overall competency and as a collection of knowledge and skills. The purpose of this study is to explore the specific workplace information fluency skills valued by employers of technical communicators, to find out how instructors perceive and teach these skills, and to suggest how these findings can inform our teaching practices. Within the framework of qualitative methodology, this study employs two data-collection instruments, including a content analysis of online job recruitment postings and a survey of technical communication instructors across the United States. The study discovers that when hiring technical communicators, employers require candidates to have skills in information processing, information technology, and critical thinking. Candidates must be able to identify their information needs, and must know how to use specified tools to gather, evaluate, and communicate information. It also reveals that although "information fluency" is a new terminology to a majority of instructors, the skill sets that constitute information fluency already existed in their knowledge. The study's last finding suggests that the opportunity for an internship is perceived as the most helpful in students' acquisition of information fluency skills. This dissertation concludes with a list of specific employer-valued information fluency skills, recommendations for program administrators and instructors for implementing information fluency, as well as recommendations for future researches on this subject.

Show moreThe utility of narrative as a persuasive mechanism has been increasingly investigated in recent years especially within the context of health behaviors. Although many studies have noted the effectiveness of narrative-based persuasive appeals, conceptual inconsistencies have made it difficult to determine what specific aspects of narrative messages lead to the most effective persuasive outcomes. In the present study, 145 female college students were randomly assigned to read one of four narrative health messages about a female freshman college students experiences with the human papillomavirus (HPV). Two elements of the narrative message structure were manipulated: the message frame (gain framed vs. loss framed), and the grammatical person of the text (first-person vs. third-person).The messages were presented via the medium of an online blog. After reading a narrative participants responded to a brief questionnaire designed to measure perceptions of threat regarding HPV contraction, perceptions of efficacy regarding HPV prevention, and intentions to get the Gardasil vaccine. Participants exposed to loss framed messages reported higher levels of perceived threat (susceptibility and severity) than participants exposed to gain framed messages although participants in the gain framed message conditions reported higher levels of perceived self-efficacy. Significant correlations were also found between levels of reported character identification and the two threat variables. No effects were found for grammatical person.

Show moreMiscommunication between controllers and pilots, potentially resulting from a high pilot cognitive load, has been a causal or contributing factor in a large number of aviation accidents. In this context, failure to communicate can be attributed, among other factors, to an inadequate human-system interface design, the related high cognitive load imposed on the pilot, and poor performance reflected by a higher error rate. To date, voice radio remains in service without any means for managing pilot cognitive load by design (as opposed to training or procedures). Such an oversight is what prompted this dissertation. The goals of this study were (a) to investigate the utility of a voice-to-text transcription (V-T-T) of ATC clearances in managing pilot's cognitive load during controller-pilot communications within the context of a modern flight deck environment, and (b) to validate whether a model of variable relationships which is generated in the domain of learning and instruction would (")transfer("), and to what extend, to an operational domain. First, within the theoretical framework built for this dissertation, all the pertaining factors were analyzed. Second, by using the process of synthesis, and based on guidelines generated from that theoretical framework, a redundant verbal display of ATC clearances (i.e., a V-T-T) was constructed. Third, the synthesized device was empirically examined. Thirty four pilots participated in the study (-) seventeen pilots with 100-250 total flight hours and seventeen with (>)500 total flight hours. All participants had flown within sixty days prior to attending the study. The experiment was conducted one pilot at a time in 2.5-hour blocks. A 2 Verbal Display Redundancy (no-redundancy and redundancy) X 2 Verbal Input Complexity (low and high) X 2 Level of Expertise (novices and experts) mixed-model design was used for the study with 5 IFR clearances in each Redundancy X Complexity condition. The results showed that the amounts of reduction of cognitive load and improvement of performance, when verbal display redundancy was provided, were in the range of about 20%. These results indicated that V-T-T is a device which has a tremendous potential to serve as (a) a pilot memory aid, (b) a way to verify a clearance has been captured correctly without having to make a (")Say again(") call, and (c) to ultimately improve the margin of safety by reducing the propensity for human error for the majority of pilot populations including those with English as a second language. Fourth, the results from the validation of theoretical models (")transfer(") showed that although cognitive load remained as a significant predictor of performance, both complexity and redundancy also had unique significant effects on performance. Furthermore, these results indicated that the relationship between these variables was not as (")clear-cut(") in the operational domain investigated here as the models from the domain of learning and instruction suggested. Until further research is conducted, (a) to investigate how changes in the operational task settings via adding additional coding (e.g., permanent record of clearances which can serve as both a memory aid and a way to verify a clearance is captured correctly) affect performance through mechanisms other than cognitive load; and (b) unless the theoretical models are modified to reflect how changes in the input variables impact the outcome in a variety of ways; a degree of prudence should be exercised when the results from the model (")transfer(") validation are applied to operational environments similar to the one investigated in this dissertation research.

Communication, in its most basic sense, is foundational for any personal, human interaction and relationship. As theatre artists, we are charged with communicating complex story lines, conceptual ideas, and emotion to an audience. Sound communication is paramount to every aspect of a musical production, be it communication between actors/characters, actor and director, amongst the production team, and arguable the most important, between the actors and the audience.

Show moreCommunication, in its most basic sense, is foundational for any personal, human interaction and relationship. As theatre artists, we are charged with communicating complex story lines, conceptual ideas, and emotion to an audience. Sound communication is paramount to every aspect of a musical production, be it communication between actors/characters, actor and director, amongst the production team, and arguable the most important, between the actors and the audience. My years of education as a Masters in Fine Arts candidate in Musical Theatre have been spent polishing my ability to communicate physical and emotional choices with greater accuracy, depth, and truth. By staging Jason Robert Brown's musical The Last Five Years and performing the role of Jamie, this performance thesis will explore, develop, and examine my mastery of the aforementioned varied forms of communication, all of which are necessary in building a successful musical production. Research will be conducted to gather information on relevant topics, including the history of The Last Five Years, the life of Jason Robert Brown, and his musical and theatrical influences. By further understanding Brown, his life, and his ideas about his works, I hope to more fully understand and communicate the message of the musical itself. A dramatic and musical structural analysis will provide further depth and insight into the piece, with the hopes of informing my production and individual performance. A thorough character analysis will provide connective tissue that will allow myself, as the actor, to more effectively communicate the psychological and emotional make up of the character Jamie. Lastly, the thesis document will culminate with a production journal, documenting the pre-production, rehearsal, and performance process. Through the journaling process, I will document and address the journey that I have experienced with the production, giving focus and attention to its many obstacles and discoveries, successes and failures, all of which have contributed to my personal growth as a young theatre artist.

Show moreDuring past two decades a variety of SAW based wireless sensors were invented and research is still in progress. As different frequencies, varied bandwidths, coding techniques and constantly changing post processing algorithms are being implemented, there is a constant need for a universal and adjustable synchronous communication system able to interrogate new generations of SAW sensors. This thesis presents the design of a multiple FPGA based communication system with an operational frequency range of 450MHz-2.2GHz capable of producing user programmed modulated signal. The synchronous receiver is designed to have interchangeable chip, replacement of which would allow adjustment of the receiver's bandwidth. Within this paper the performance of the system is only evaluated at 915MHz centered 20MHz bandwidth region. An OFC temperature sensor was interrogated. Post-processing algorithms, measurement results, and proposals for the future use of the system are presented. Detailed overview of the structure and performance of every functional block along with design considerations are analyzed. Previously designed Matlab based software was adapted for post processing of the received signal. New software with simplified GUI was designed for programming of the desired signal.

Show moreThis research examines impression management strategies high-ranking organizational executives employ to create an identity for themselves and their companies via executive authored Weblogs (blogs). This study attempts to identify specific patterns of impression management strategies through a deductive content analysis applying Jones' (1990) taxonomy of self-presentation strategies to this particular type of computer mediated communication. Sampling for this study (n=227) was limited to blogs solely and regularly authored by the highest-ranking leaders of Fortune 500 companies. The study revealed that executive bloggers frequently employed impression management strategies aimed at currying competency attributes (self-promotion), likeability (ingratiation), and moral worthiness (exemplification) to construct and shape a positive identify for themselves and their organization for their publics. Supplication strategies were used less frequently, while intimidation strategies were rarely used.

Show moreThe main objective of this research was to investigate how people use Facebook within the context of their romantic relationships from an attachment theory perspective. In the present study, a convenience sample (n = 179) completed an online survey with questions about Facebook use, attachment style, uncertainty-related behaviors, jealousy, relationship satisfaction and commitment. Results indicate that 1) there is a positive correlation between jealousy and Facebook use; 2) also, there is a positive correlation between jealousy and the time an individual spends viewing their partnerÂÂ's profile; 3) further, jealousy is positively related to uncertainty-reducing behaviors. Taken together, these results support the assertion that there is a downward spiral involving jealousy and Facebook. Results also showed that there are two types of uncertainty-related behaviors: antisocial behaviors and territorial behaviors. Anxious-ambivalent attachment styles were found to engage in antisocial behaviors the most, whereas secure individuals engaged in antisocial behaviors the least. The findings provide ample areas for future research on social networking sites and relationship variables.

Show moreCommunication has been identified as a critical component in the outcome of emergency response. Post-mortems of "what went wrong" in disaster responses often point toward breakdown in communication between first responders, those directing rescue efforts, and the general population as one of the primary impediments to rendering timely aid and communicating adequate safety and weather information. Due to the high resilience, relatively low costs, and advanced features of modern hand-held communication devices, these devices are in a position to drastically improve communication flow during emergency management situations. Due to the lack of official implementation of these devices and the lack of the establishment of standard guidelines for device selection, the use of hand-held communication devices in emergency management is yet to be optimized. Island nations such as the Bahamas, which face unique challenges in regard to emergency management due to geographical, infrastructural, political, and cultural hurdles which are found in the region, can especially benefit from the optimized implementation of hand-held communication devices in emergency management. This study examined current emergency response procedures in The Bahamas, created a baseline for the current use of hand-held communication devices by Bahamian emergency management officials and civilians, identified the communication needs of Bahamian emergency management officials and civilians, and proposed a model for the selection of hand-held communication devices based upon human factors principals and focusing on user priorities. This study began with a focus group interview which included 14 Bahamian emergency management officials in order to gain an understanding of current Bahamian emergency response procedures and the communication challenges faced by emergency management officials during high consequence emergencies. A paper based survey was conducted, in which 31 Bahamian emergency management officials answered demographic, skill level, and functionality questions related to the use of hand-held communication devices to support emergency related activities including those directed toward preparation, mitigation, and response. These emergency management officials provided invaluable input based upon their practical experience in high consequence emergency situations. 155 Bahamian civilians participated in a similar survey which was a reduced version of the survey used for emergency management officials. Both surveys included questions in regard to the background information of the participants, previous handheld communication experience, device performance, and what other communication devices were being utilized. The surveys were analyzed using statistical methods of categorical data analysis and correlations were identified. Several communication needs which were categorized as infrastructure, organizational, and equipment needs as well as a hierarchy of device selection factors in regard to the use of hand-held communication devices during emergency management situations were identified. The analytic hierarchy process (AHP) was used in order to determine the priorities of each of the identified device selection factors and a model for the selection of hand-held communication devices used to support communication flow in high consequence emergency management was proposed.
