Arts of concealment rhetoric and ethics in the age of wireless computing

Barnett, Richard Scot The University of Wisconsin - Madison 2010 해외박사(DDOD)

This dissertation examines the function and importance of concealment in rhetoric and in communication more generally. Tracing various accounts of the concept across the history and theory of rhetoric, I show that concealment in rhetoric has been figured in at least two defining ways: the first more problematically as a form of purposeful dissembling or deception and the other more positively as a potentially useful tactic that speakers or writers may learn to employ in order to better persuade their audiences. While each of these accounts has been helpful at specific moments in rhetoric's history, I argue that both leave rhetoricians ill-equipped to address other ways concealment functions in communication. To reassess the problem of concealment in rhetoric and what it might mean to think concealment otherwise, I turn to two areas---phenomenology and wireless computing---where concealment has been figured differently than in the rhetorical tradition. In contrast to the largely "instrumental" conceptions of concealment scattered across the rhetorical tradition, researchers in phenomenology and wireless computing tend to conceive of concealment as a necessary and generative feature of human existence itself, one that shapes, in ways that cannot be directly known or controlled, how we eventually come to understand ourselves and communicate with others in the world. Through phenomenological examinations of handheld cellular phones, personal digital assistants (PDAs), and other digital devices embedded imperceptibly throughout the built environment, I propose in this project another, less instrumental or human-centric, way of understanding concealment that acknowledges its integral role in constituting the very possibilities of communication and, indeed, all lived experience. In so doing, I develop a more nuanced theoretical framework---what I term a "rhetorical phenomenology of human-technology relations"--- that enables rhetoricians to more productively address the various forms concealment takes in wireless computing culture and the bearing these forms have on how we learn to live and communicate with others today.

Investigating inquiry teaching and learning: The story of two teachers

Barnett, George Michael Indiana University 2003 해외박사(DDOD)

Current national and state science standards emphasize inquiry as the central strategy to teaching science. Yet, these standards do not give specific prescriptions for how to conduct inquiry in within the context of a K–12 classroom. Fortunately, many teachers are creative and intelligent decision makers who have their own perspectives on and definitions of inquiry and will no doubt attempt to implement inquiry in ways that they feel best benefits their students given the constraints of their context. This study balanced “insider” and “outsider” perspectives to examine how two teachers' conceptions of inquiry changed over time, how those changes evolved, and how these teachers overcame the difficulties inherent with inquiry-based teaching. A naturalistic and interpretive research approach was used to collect and analyze the data. This approached entailed classroom observations, interviews, field notes, and analysis of teachers' journals. Findings indicate that inquiry-based teaching practices are inherently a local phenomenon that emerges within and through the interplay among a teacher's beliefs, student questions and goals, the teacher's goals, and the social context of the teacher's classroom. Results also indicate that teachers' conceptions of inquiry change gradually over time and not as of the result of single critical events or stages and are intimately tied to their teaching context.

Medea in the media: Narrative and myth in print media coverage of women who kill their children

Barnett, Barbara Ann The University of North Carolina at Chapel Hill 2003 해외박사(DDOD)

Motherhood has been represented in fact and fiction as a supreme calling, a happy achievement, a heavenly blessing, a womanly profession, the pinnacle of femininity. Women who become mothers are supposed to be guided by “natural” feminine instincts that make them instantly loving, all-knowing, and selfless. Many 20<super>th</super> century feminists have challenged this notion and have challenged the mass media, including journalists, to offer more realistic representations of motherhood—representations based on women's lived experiences rather than greeting card sentiments and Victorian images. Some scholars suggest circumscribed views of motherhood harm women because they discourage them from seeking help when they cannot or do not mother well. The news media are today's modern storytellers, and as such, transmit information. However, the media also transmit values and ideals. Using qualitative analysis, this dissertation explored the dominant narratives in news articles about women who killed their children and examined myths embedded in those narratives. The analysis included 10 separate incidents of infanticide, documented in 229 news stories published in mainstream U.S. newspapers during the past 15 years. Findings revealed four distinct narratives: (1) The perfect/imperfect mother, which positioned women who killed their children as either insane or evil; (2) The good mother, which included stories from women who killed their children, who said they loved their children but also admitted they harmed them; (3) The accountable mother, which revealed that women were held to a higher standard of parenting than fathers, and which positioned men and others in the community as victims of devious women; (4) The wounded community, in which the community was personified and presented as the victim of a crafty, deceitful mother. Using a framework of “master myths” in journalism, the analysis revealed that mothers were presented as victims, scapegoats, and tricksters. In addition, findings suggested that journalists employed “maternal myths” in articles about women who killed their children: Women were presented as fallen angels and rebels and were compared with a perfect, mythical “Good Mother.” However, findings also revealed cracks in dominant narratives and myths, as journalists reported women's discussions of their own ambivalent maternal experiences.

Measurement of free electron density during photon irradiation

Barnett, Frank M University of Minnesota 2011 해외박사(DDOD)

To disrupt molecules and therefore make them and their accompanying biological cells inactive, it is generally necessary to create more than one ionization within the molecule. This study is to use an electron linear accelerator to generate high energy photons, which then irradiate macroscopic volumes of animal cells in a measurement enclosure. During irradiation the conductivity of the volume will be measured, and at the end of irradiation, the decay of conductivity will be measured as a function of time. In order to obtain accurate timing of the cessation of radiation, a timing device has been constructed. It will be tested prior to the start of the measurements. The purpose of this study is to establish whether photon irradiation delivered in short, high intensity bursts, would be more effective in destroying malignant cells by producing multiple ionization within molecules of the cell.

Essays on Self-Knowledge and the Boundaries of the Mind

Barnett, David James New York University 2013 해외박사(DDOD)

My dissertation examines the epistemic interaction between internal and external perspectives on one's own beliefs. For example, if you believe that it will rain, then from your internal perspective it appears to be a fact about the world that it will rain. If on the other hand you merely know of another person's belief that it will rain, then from your external perspective this appears merely to be a fact about a particular person's state of mind, which might support that it will rain only against a background of further evidence concerning that person's track record, reliability, and so forth. These two perspectives can interact because just as you can learn evidence about the reliability of another person's beliefs, you can learn the same kind of evidence about your own beliefs. I think that the interaction between these perspectives plays a central role in a number of debates in epistemology, and my dissertation examines a few of these in particular: introspective self-knowledge, the epistemology of memory and testimony, and epistemic circularity both in a contemporary and a historical context. The submitted manuscript consists of three stand-alone essays: a critical essay on transparency accounts of how you know what you believe that draws a broader lesson about the nature of justified inference; a historical essay on the Cartesian Circle that explores a widely overlooked interaction between Descartes' epistemology and his metaphysics of persons; and finally an essay which develops threads from the earlier essays in an effort to explain how you can know that your internal cognitive faculties are reliable based on epistemically prior knowledge of the external world.

Untangling the web of hate: Are online "hate sites" deserving of First Amendment protection?

Barnett, Brett Aaron Bowling Green State University 2005 해외박사(DDOD)

This dissertation extends the developing communication research literature about Internet hate speech by juxtaposing legal analysis with qualitative content analysis. In particular, the author identifies the various federal-court approved First Amendment tests for assessing the constitutionality of both publicly-communicated (non-mass-mediated) hateful speech and Internet content, then examines a sample of U.S.-based online "hate sites" to ascertain whether they contain constitutionally proscribable content under those standards. The population of hate sites was acquired from the Spring 2004 edition of the "Intelligence Report" published by the Southern Poverty Law Center (SPLC). A multi-part sampling procedure was applied to this large list of websites to create a manageable, but representative, sample for content analysis. The final sample consisted of at least one representative site from each of the "hate website" categories identified by the SPLC: "Ku Klux Klan" (2); "Neo-Nazi" (1); "Racist Skinhead" (1); "Neo-Confederate" (1); "Christian Identity" (1); "Black Separatist" (2); and "Other" (2). The two websites from the "Other" hate group category included a site maintained by a White conservative organization and one of the few American hate sites operated by a Jewish group. The process of collecting content from the ten sites in the final sample began on November 18, 2004 and ended on December 25, 2004. Analysis was conducted on all hate-group-maintained, publicly-accessible content posted on the sampled websites. In conducting this analysis, the author identified the thematic and non-textual content of, as well as the persons that were the targets of hatred on, these hate sites. However, the study failed to uncover any content on the sampled websites that would likely be deemed constitutionally proscribable under the Supreme Court's "Miller," "true threats," "clear and present danger," or "bad tendency" tests, the First Amendment standards that the author determined could be used to evaluate the constitutionality of hate sites. Based on his findings, the author argues it appears that alternatives to governmental speech regulation, particularly the use of user-based Internet filtering technologies, need to be considered for regulating content posted on the publicly-accessible areas of U.S.-based hate websites.
