Speech intelligibility measures how much a speaker can be understood by a listener. Traditional measures of intelligibility, such as word accuracy, are not sufficient to reveal the reasons of intelligibility degradation. This dissertation investigates the underlying sources of intelligibility degradations from both perspectives of the speaker and the listener. Segmental phoneme errors and suprasegmental lexical boundary errors are developed to reveal the perceptual strategies of the listener. A comprehensive set of automated acoustic measures are developed to quantify variations in the acoustic signal from three perceptual aspects, including articulation, prosody, and vocal quality. The developed measures have been validated on …

This study articulates a framework of writing strategies and validates the framework by using it to examine the writing process of researchers as they write journal articles for publication. The framework advances a definition of writing strategies and a classification system for categorizing strategies that is based on strategic goals. In order to develop the framework, I first synthesize existing literature on writing strategies found in second language writing studies, composition studies, and second language acquisition. I then observe the writing process of four researchers as they write journal articles for publication and use the framework to analyze participants’ goals, …

This dissertation aimed to identify the factors that facilitated the friendship initiation, development, and maintenance between Taiwanese and Chinese students and the influential relationship among those factors. Nine Taiwanese and nine Chinese students studying at one Taiwanese university were recruited for this study. The Chinese students were in Taiwan for at least two years. The participants were friends with the other party for at least 8 months. This study was divided into three stages. In the first stage, participants were required to provide factors that facilitated their friendship with the other party. Fifty ideas were collected. In the second stage, …

This descriptive research used social network analysis to explore the influence of relationships and communication among hospital nursing (RN, LPN, CNA) and discharge planning staff on adherence to evidence-based practices (EBP) for reducing preventable hospital readmissions. Although previous studies have shown that nurses are a valued source of research information for each other, there have been few studies concerning the role that staff relationships and communication play in adherence to evidence-based practice. The investigator developed the Relational Model of Communication and Adherence to EBP from diffusion of innovation theory, social network theories, relational coordination theory, and quality improvement literature. The …

While numerous studies have examined the nature of masculinity, scholars seldom seek to determine the meaning of manhood or to explore which types of individuals are culturally permitted to call themselves men. One scholarly approach suggests that the meaning of a cultural category can best be illuminated through examining marginalized examples within that category. Based on this assumption, this project illuminates cultural understandings of manhood in the United States by examining the experience of men within two marginalized categories--gay and transsexual--who have often found themselves fighting for the right to call themselves men at a time when hegemonic assumptions about …

The field of intercultural communication emerged from demonstrated need in the public sector and has roots in cultural anthropology. There is continued need in academic and practitioner domains for improved ways to effectively engage across cultures. To do so, it is necessary to develop approaches that enable a person to take the emic perspective of an intercultural Other. Worldview is a promising concept in several fields, such as anthropology and cross-cultural psychology, but remains undeveloped in the field of intercultural competence. In addition, existing conceptualizations and approaches to identify worldviews are too comprehensive or ambiguous to be useful. The purpose …

Currently, there has been limited research on evaluating the social media use and competency level of registered dietitian/nutritionists (RD/N). With health information increasingly sought on social media, it is imperative to understand the social media competency of health professionals. The social media use, reach, and competency level of a nationwide RD/N sample was assessed utilizing an online survey. The sample (n=500) while mostly female (97%) was representative of RD/Ns compared to the nationwide statistics from the Commission on Dietetic Registration. The sample included RD/Ns from forty-six states with California (n=44), New York (n=42), and Texas (n=34) having the largest proportion …

Dangerous drinking on college campuses is a significant public health issue. Over the last decade, the National Institute on Alcohol Abuse and Alcoholism and the U.S. Department of Health and Human Services have called on universities, community leaders, policymakers, parents and students to work together to develop effective, research based alcohol prevention and/or intervention programs. Despite such calls, parent-based prevention programs are relatively rare on college campuses, and there is a paucity of research on the ways in which parents influence their emerging adult children's drinking behaviors. The present project is designed to help address this need. Grounded in social …

Broaden and build theory (BBT; Fredrickson, 1998; 2001) postulates that positive emotions expand the scope of one's attention and thought-action repertoires (Fredrickson & Branigan, 2005). Within the boundaries of BBT, the undoing hypothesis (Fredrickson, 1998, Fredrickson & Levenson, 1998) argues that positive emotions themselves do not bring forth specific action tendencies or urges; therefore, they do not consequently require an increase in cardiovascular activity to carry out the urge. On the other hand, positive emotions have evolved to subdue the cardiovascular response previously initiated by negative emotions. This dissertation proposes that the real power of positive emotions might be to …

This thesis deals with the analysis of interpersonal communication dynamics in online social networks and social media. Our central hypothesis is that communication dynamics between individuals manifest themselves via three key aspects: the information that is the content of communication, the social engagement i.e. the sociological framework emergent of the communication process, and the channel i.e. the media via which communication takes place. Communication dynamics have been of interest to researchers from multi-faceted domains over the past several decades. However, today we are faced with several modern capabilities encompassing a host of social media websites. These sites feature variegated interactional …
