The centerpiece is a stand alone research portrait that tells a story about how an external program, a willing and ready school community, and a skillful school leader reinforced each other to achieve a shared vision under challenging conditions. From an under-subscribed school in chaos and lacking focus, the subject school transformed into a vibrant, highly sought school with a pervasive, environmentally-oriented culture and curriculum. Portraiture methods were adapted to a utilization-focused evaluation purpose, drawing on …

Telling Our Stories: A Phenomenological Study Of The Leader’S Gendered Experience Of Self-Disclosing, Dee Giffin Flaherty

Antioch University Dissertations & Theses

Leadership is a personal process that involves creating communities and influencing change through relationships of influence. This research explores one aspect of leadership, that of self-disclosing. The self-disclosure of leaders affects all aspects of leadership. Self-disclosure is personal in that people’s voices are unique and come from their sense of self. The appropriate use of self-disclosure can facilitate increased self-awareness, and greater mental and physical health. Leaders can influence change by the strategic sharing of their disclosures. Communities are built when people can identify with leaders stories and be guided toward a shared vision. The purpose of this study is …

We Take From It What We Need: A Portraiture Approach To Understanding A Social Movement Through The Power Of Story And Storytelling Leadership, Karen Lynn Gilliam

Antioch University Dissertations & Theses

This study examined a social movement through the power of story and storytelling and its influence on behavior from a purposeful sampling of individuals who heard the story of Joan Southgate’s journey. Ms. Southgate, a 73-year-old African-American, walked the 519 miles of the underground-railroad across Ohio, Pennsylvania, New York and into Canada. The grand narrative of the underground-railroad is a never-ending story, subject to change with each re-telling and/or unveiling of polyphonic microstories. Stories have the ability to capture emotion and reason, hearts and minds. While storytelling is thought to be a most powerful means of communicating, very little scholarly …

Adjusting The Margins: Building Bridges Between Deaf And Hearing Cultures Through Performance Arts, Luane Ruth Davis Haggerty

Antioch University Dissertations & Theses

This study addresses a gap in scholarship on leadership styles in the Deaf community. There is an invisible style of leadership differing from the mainstream culture not previously addressed in the literature at any depth. My study is composed of three interlocking parts; the practice of anthropology: fieldwork, analysis, and presentation. The foundation for my fieldwork, is an "archeology of the structure of the perceived world" (Merleau-Ponty), using the holding environment of the rehearsal process and the structural process of an acting technique called Del-Sign. Del-Sign is a fusion acting style created by combining American Sign Language and the Delsarte …

Leadership As Teaching: Mapping The Thinking Of Administrators And Teachers, Mary Ellen Steele-Pierce

Antioch University Dissertations & Theses

Leading and teaching both involve processes that permit others to transform their thinking. Yet there has been little systematic, empirical research to connect the two. This exploratory study examines K-12 educational leadership asking: What are the similarities and differences in the ways school administrators think about "leading" compared to the ways teachers think about "teaching"? This mixed methods study offers an examination of whether administrators think about their work in terms of "the vital teaching role of leadership" (Burns, 1978, p. 425) by creating and comparing three sets of concept maps, one for teachers and administrators and one for each …

Selecting Leadership: An Analysis Of Predictors In Assessing Leadership Potential, Andrea L. Zavakos

A Peer-to-Peer(P2P) network is the most popular technology in file sharing today. With the advent of various commercial and non-commercial applications like KaZaA, Gnutella, a P2P network has exercised its growth and popularity to the maximum. Every node (peer) in a P2P network acts as both a client and a server for other peers. A search in P2P network is performed as a query relayed between peers until the peer that contains the searched data is found. Huge data size, complex management requirements, dynamic network conditions and distributed systems are some of the difficult challenges a P2P system faces while …

Recommendations For A Comprehensive Identity Theft Victimization Survey Framework And Information Technology Prevention Strategies, Sara Berg

Theses

While steps have been undertaken in the last five years to better understand the problem of identity theft, there has been little research done in the areas of high tech crime victim profiling and prevention. Most studies focus on victim demographics without examining ways in which the victimization may have been facilitated technologically. Attempts to look at precipitating behaviors in the context of victimization are limited. As such, a weak empirical base exists on which to generate additional research and potential solutions to identity theft victimization. This thesis bridges previous identity theft research with other empirical studies in order to …

Symmetric Private Information Retrieval Via Additive Homomorphic Probabilistic Encryption, Laura Lincoln

Theses

Suppose there is a movie you would be interested in watching via pay-per-view, but you refuse to purchase the feed because you believe that the supplier will sell your information to groups paying for the contact information of all the people who purchased that movie, and the association of your name to that purchase could hinder career, relationships, or increase the amount of time you spend cleaning SPAM out of your mailbox. Private Information Retrieval (PIR) will allow you to retrieve a particular feed without the supplier knowing which feed you actually got, and Symmetric Private Information Retrieval (SPIR) will …

Iron In Ice Cores From Law Dome: A Record Of Atmospheric Iron Deposition For Maritime East Antarctica During The Holocene And Last Glacial Maximum, Ross Edwards, Peter N. Sedwick, Vin Morgan, Claude Boutron

OES Faculty Publications

Total dissolvable iron (TDFe) was measured in sections of ice cores recovered from Law Dome on the coast of Wilkes Land, East Antarctica. These samples include ice dating from the Last Glacial Maximum (LGM), the Last Deglaciation, and the early and mid Holocene as well as samples from the Anthropocene that have been dated with seasonal to annual resolution. Combining our TDFe concentration data with estimates of the ice accumulation rate, we estimate the atmospheric iron deposition for Law Dome and the adjacent Southern Ocean during these periods. Our results indicate that the atmospheric iron deposition flux to this region …

Comparison Of Celp Speech Coder With A Wavelet Method, Sriram Nagaswamy

University of Kentucky Master's Theses

This thesis compares the speech quality of Code Excited Linear Predictor (CELP, Federal Standard 1016) speech coder with a new wavelet method to compress speech. The performances of both are compared by performing subjective listening tests. The test signals used are clean signals (i.e. with no background noise), speech signals with room noise and speech signals with artificial noise added. Results indicate that for clean signals and signals with predominantly voiced components the CELP standard performs better than the wavelet method but for signals with room noise the wavelet method performs much better than the CELP. For signals with artificial …

The Application Of Scenario Based Recurrent Training To Teach Single Pilot Resource Management (Srm) Under The Faa Industry Training Standards (Fits) Program, Francis H. Ayers

Journal of Aviation/Aerospace Education & Research

Research indicates that improving a pilot's capability to exercise sound judgment and make informed and timely decisions may significantly improve flight safety. One approach to this problem is the introduction of scenario-based training (SBT) into flight training curriculums. At the request of the Cirrus Owner's and Pilots Association (COPA), the author developed and conducted four 3-hour scenario based seminars embodying these concepts and collected initial data from the 54 participants. A longitudinal study of this initial group will form the basis for additional research.

Analysis Of Effective Mechanical Properties Of Thin Films Used In Microelectromechanical Systems, Ajay Pasupuleti

Theses

This research aims at analyzing the effective mechanical properties of thin film materials that are used in MEMS. Using the effective mechanical properties, reliable simulations of new or slightly altered designs can be performed successfully. The main reason for investigating effective material properties of MEMS devices is that the existing techniques can not provide consistent prediction of the mechanical properties without time-consuming and costly physical prototyping if the device or the fabrication recipe is slightly altered. To achieve this goal, two approaches were investigated: soft computing and analytical. In the soft computing approach, the effective material properties are empirically modeled …

Streaming Video Performance And Enhancements In Resource-Constrained Wireless Networks, Justin James Madigan

Theses

Streaming video is an increasingly popular application in wireless networks. The concept of a live streaming video yields several enticing possibilities: real-time video conferencing, television broadcasting, pay-per-view movie streaming, and more. These ideas have already been explored via the internet and have met with mixed success, largely due to the shortcomings of the underlying network. Taking streaming video to wireless networks, then, poses several significant challenges. Wireless networks are inherently more susceptible to failures and data corruption due to their unstable communications medium. This volatility suggests serious drawbacks for any implementation of streaming video. Video frame errors, jitter, and even …

Development And Test Of A Kinematical Method For Estimating Rotation Using The Acceleration Of A Rigid Body, Douglas A. Carr

Theses

In this work, the feasibility of a novel method for combining inertial information gathered from accelerometers to calculate an estimate for rotational information independent of rate gyro measurements is investigated. The concept uses two, distinctly placed, parallel accelerometers on a rigid body to estimate rotational acceleration by comparing the difference in sensed acceleration caused by rotation. Since the estimation is independent of available rate gyro data, optimization of drift and scale factors can be used to calibrate the accelerometers in a real time fashion. Experimental trials were conducted on a small mobile robotic platform, due to the eventual objective of …

Landscapes Of Imagination: A Critical Analysis Of Art Textbooks, Lynda C. Kerr

College of Graduate Studies: Theses & Dissertations

Author's abstract: This qualitative study examined imagination in secondary art textbooks, both historically and in the current educational climate. An arts-based inquiry, as described by Barone & Eisner (Jaeger, 1988), investigated how imagination is manifested in some art books, how the standards movement has tended to limit imagination in art textbooks, and how art textbooks could expand students' imaginations. Using a framework based on the theories of Dewey (1934/1980), Greene (2001), and Eisner (2002), four art textbooks were analyzed for their qualities which expand students' imaginations. The study described a design for an imaginative art textbook. Analysis focused on the …

Democracy And Oversight, Riccardo Pelizzo, Rick Stapenhurst

Research Collection School of Social Sciences

In the course of the past decade, political science has started paying increasing attention to the study of legislative oversight, which had been previously been described as an important but inadequately researched area of legislative activity (Lees, 1977). Lees’ comment is particularly true with regard to comparative analyses of oversight tools and practices. Some studies have recently discussed the instruments of legislative oversight (Maffio, 2002), other studies have instead investigated how legislative oversight relates to both political variables (Pennings, 2000; Damgaard, 2000; Pelizzo and Stapenhurst, 2004a) and socio-economic conditions (Pelizzo and Stapenhurst, 2004b). In spite of this renewed interest in …
