Show moreTechnical and professional communicators have in recent research been challenged to make significant contributions to the field of knowledge management, and to learn or create the new technologies allowing them to do so. The purpose of this dissertation is to make such a combined theoretical and applied contribution from the context of the emerging discipline of Texts and Technology. This dissertation explores the field of knowledge management (KM), particularly its relationship to the related study of artificial intelligence (AI), and then recommends a KM software application based on the principles of narratology and narrative information exchange. The focus of knowledge is shifted from the reductive approach of data and information to a holistic approach of meaning and the way people make sense of complex events as experiences expressed in stories. Such an analysis requires a discussion of the evolution of intelligent systems and narrative theory as well as an examination of existing computerized and non-computerized storytelling systems. After a thorough discussion of these issues, an original software program that is used to collect, analyze, and distribute thematic stories within any hierarchical organization is modeled, exemplified, and explained in detail.

Show moreThis study examined the media portrayals of Roma in the United States by taking a closer look at (")Gypsy crime(") articles in a purposive sample of newspaper articles. These newspaper articles give details of (")confidence(") crimes and name the alleged perpetrators as Roma or members of the ethnic minority group commonly known as Gypsies. A textual analysis was conducted of 23 articles appearing in the South Florida Sun-Sentinel from August 16, 2011 to February 8, 2013 covering fraud charges against several members of the Marks family. This primary evaluation narrowed the initial sample to nine articles that contained references to Roma, Romani, or Gypsy. Further analysis of these nine articles revealed four major categories of findings regarding the representation of the ethnic minority. The categories included: 1) the pairing of the preferred term, Roma with the pejorative term, Gypsy; 2) reinforcement of stereotypes; 3) portrayal of the ethnic group as foreign others; and 4) Roma portrayed as a threat to the dominant culture and its members. The theoretical bases for the study included Social Stigma Theory (Goffman, 1963) and Orientalism (Said, 1978) both of which offer a critical lens through which to examine the portrayals of this ethnic minority.

Show moreIt has been estimated that one third of the world's population does not have access to "adequate" health care. Some 1.6 billion people live in countries experiencing "concentrated" acquired immune deficiency syndrome (AIDS) epidemics. Many countries in Africa -- and other low-income countries -- are in dire need of help providing adequate health care services to their citizens. They require more hands-on care from Western health workers -- and training so more African health workers can eventually care for their own citizens. But these countries also need assistance acquiring and implementing both texts -- the body of medical information potentially available to them -- and technology -- the means by which that information can be conveyed. This dissertation looks at these issues and others from a multi-faceted approach. It combines a survey of the developers of Web sites designed for use by health workers in low-income countries and a proposal for a novel approach to communication theory, which could help improve health communication and other social marketing practices. It also includes an extensive review of literature regarding a number of topics related to these issues. To improve healthcare services in low-income countries, several things should occur. First, more health workers -- and others -- could visit African countries and other places to provide free, hands-on medical care, as this researcher's group did in Uganda. Such trips are ideal occasions for studying the cultural differences between "mzungu" (white man) and the Ugandan people. A number of useful medical texts have been written for health workers in low-income countries. Others will be published as new health information becomes available. But on what medium will they be published? Computers? Personal digital assistants? During the past 10 years the Internet became an ideal venue for conveying information. Unfortunately, people in target countries such as Uganda encounter cultural differences when such new technologies are diffused. This dissertation looks at cultural and technological difficulties encountered by people in low-income countries who attempt to diffuse information and communication technologies (ICT). Once a technology has been successfully adopted, someone will look for ways to use it to help others. There are hundreds of sites on the Internet -- built by Web developers in Western countries -- that are designed for use by health workers in low-income countries. However, these Web developers also experience cultural and technological differences, based on their knowledge of and attitudes toward best practices in their field. This research includes a survey of Web developers which determined their attitudes toward best practices in their field and tested this researcher's hypothesis that there is no significant difference among the developers' attitudes toward the content on their sites, their audience's cultural needs and the various technological needs their audience has. It was found that the Web developers agree with 17 of 18 perceived best practices and that there is a significant difference between Web developers' attitudes toward their audience's technological needs and their attitudes toward quality content and the audience's cultural needs. Creation of the survey herein resulted in this researcher generating a new way of thinking about communication theory -- called digital research cycles. The survey was based on a review of literature and is rooted in the belief that any successful communication of a computer-mediated message in the information age is a behavior which is influenced by the senders' and receivers' attitudes and knowledge about textual style, the audience, technology and the subject matter to which the message pertains.

Show moreThis study analyzed the scholarly discussions surrounding the topic of animal testing for vaccine potency and safety in humans. The primary stakeholders in this discussion are the scientists, medical professionals, and researchers who are involved in animal models and alternative testing methods, specifically related to vaccine development. The debate among these professionals regarding alternative methods, which encompasses any testing approach that does not involve animals, has been analyzed. This project looks at the argument from a historical perspective, which provides background context for the current debate and an understanding of how the current arguments originated. The changing mindset over time of using animals has been explored, as well as conversations and arguments about alternative methods.Research questions and prior questions consider the conversation's historical influences on this present day debate and are answered in this analysis. Persuasive language has been looked at, with a consideration of how it is used both within and outside the research community, as well as the influences the various stakeholders have on one another. The burgeoning field of the rhetoric of health and medicine provides a forum and a community of scholars for a rhetorical analysis such as this one to be discussed and the findings considered for other rhetorical studies. This research design project provides a comprehensive rhetorical analysis that uses the topoi theory and a textual-intertextual analysis as a framework, along with detailed coding of the texts. This project shows the advantages of a combined rhetorical approach that leads to understanding a debate through identifying multiple layers of argument. The findings and its implications for those within rhetoric, the scholarly community, as well as the scientific field are discussed in the final chapter.

Show moreThis study investigated the most common frames used in news coverage of the Church of Scientology from 2009 to 2013. Using textual analysis, with framing and public relations theories as lenses, this study examined recent news coverage (-) both print and television (-) to identify frames used, and the potential public relations crises the Church is currently facing due to this media exposure. Analysis showed three major frames used during coverage, along with their corresponding sub-frames, which highlight certain aspects of the frame: Culture of Abuse (Imprisonment, Controlling, Family Disconnection, Exploitation of Children, Violence, and Financial Abuse), The Information Paradox (Conflicting Information, Simple Misunderstanding, and Non-Traditional Approach), and Leadership Issues (The Problem Lies with Leadership, Celebrity Obsession). Also uncovered were three potential public relations crises: The Mistreatment of Church Members, The Misuse of Funds, and Bad Communication Strategy. The research showed a strong strategic preference of the Church to use legal tactics or denial strategies when dealing with crises. A review of public relations theory suggests that the Church use a more open approach and also incorporate mortification strategies to accept blame and repair their damaged image.

Show moreThis dissertation addresses the problem of describing images using visual attributes and textual tags, a fundamental task that narrows down the semantic gap between the visual reasoning of humans and machines. Automatic image annotation assigns relevant textual tags to the images. In this dissertation, we propose a query-specific formulation based on Weighted Multi-view Non-negative Matrix Factorization to perform automatic image annotation. Our proposed technique seamlessly adapt to the changes in training data, naturally solves the problem of feature fusion and handles the challenge of the rare tags. Unlike tags, attributes are category-agnostic, hence their combination models an exponential number of semantic labels. Motivated by the fact that most attributes describe local properties, we propose exploiting localization cues, through semantic parsing of human face and body to improve person-related attribute prediction. We also demonstrate that image-level attribute labels can be effectively used as weak supervision for the task of semantic segmentation. Next, we analyze the Selfie images by utilizing tags and attributes. We collect the first large-scale Selfie dataset and annotate it with different attributes covering characteristics such as gender, age, race, facial gestures, and hairstyle. We then study the popularity and sentiments of the selfies given an estimated appearance of various semantic concepts. In brief, we automatically infer what makes a good selfie. Despite its extensive usage, the deep learning literature falls short in understanding the characteristics and behavior of the Batch Normalization. We conclude this dissertation by providing a fresh view, in light of information geometry and Fisher kernels to why the batch normalization works. We propose Mixture Normalization that disentangles modes of variation in the underlying distribution of the layer outputs and confirm that it effectively accelerates training of different batch-normalized architectures including Inception-V3, Densely Connected Networks, and Deep Convolutional Generative Adversarial Networks while achieving better generalization error.

Show moreThere are many possible sources for youth to become educated about sexuality and reproduction, however the media are cited as particularly powerful and prominent sources of information (Jaworski, 2009). Particularly in an era in which abstinence-only messaging dominates sex education, media become a source to which young people turn and where they receive much of their sex-based messaging. Due to backlash over problematic content that perpetuates gender stereotypes and relays harmful messages about sex and sexuality, some magazines, including Teen Vogue, have attempted to shift towards more feminist-minded content (Keller, 2011, Milkie, 2002). This study is a qualitative critical feminist media analysis that examined the framing of sex, sexuality, and reproduction content in a sample of 60 Teen Vogue articles, an online publication that targets adolescents and young adults. The analysis revealed that overall, articles conveyed positive representations of sexuality, advocating for affirming and evidence-based sex education, self-empowerment through knowledge, and comprehensive reproductive healthcare for all. However, contradictory frames of sex stigmatization and a reproductive rights framework that advocates primarily for abortion rights were still highly prevalent in the data. Considering media is a significant component of the sexual socialization of youth, Sex Positive framing of sexuality which prioritizes pleasure, healthy relationships and sexual dynamics, and inclusive and affirmative sex education helps to create new narratives in media concerning how sex is viewed. These messages may have positive impacts by creating healthier sexual scripts and becoming dominant narratives in the future. However, articles in the data also utilized fear-mongering tactics that are notoriously used in abstinence-only sex education. These messages aid in further stigmatizing young people not only for having sex but also for not being informed of the potential associated risks, creating a harmful paradox that may counteract the goals of sexual health and sex positivity. Additionally, reproductive rights and reproductive justice messaging and the presentation of policy updates relevant to young readers has the potential to inform and socialize young people to be better informed about sex and sexuality, which may, in turn, lead to greater sexual empowerment. Such messaging may also empower youth activists in a time of political turmoil, connecting teen readers to what is going on around them, and providing concrete actions they can take to create political change. ?
