Thereby Become A Monster: Complex Organizations And The Torture At Abu Ghraib, Janine A. Bower

Dissertations

Reasearch and theory on organizational crime and deviance suggest organizational offending includes aspects of the environment, organizational characteristics (such as tasks, structure, and processes), and cognition, and is systematically produced by the combination of these three. This research is an examination of the organization of the Abu Ghraib detention and interrogation facility in Iraq, the location of prison abuses now made infamous following their public disclosure in 2004. An ethnographic content analysis of documents was performed to probe organizational culture, structure and processes, and their intersection with individual biographies and contextual forces. While public questions focused on why seemingly ordinary …

A New Model For Cooperative Mobility In Support If Qos In Manets With Heterogeneous Autonomy Requirements, Ghassen Ben Brahim

Dissertations

Modern mobile ad-hoc networks (MANETs) frequently consist of nodes which exhibit a wide range of autonomy needs. This is particularly true in the settings where MANETs are model compelling, i.e. battlefield, response & rescue, and contexts requiring rapid deployment of mobile users. The time-critical nature of the underlying circumstances frequently requires deployment of both manned and unmanned nodes, and a coordination structure which provides prioritized tasking to them.

In classic ad-hoc networks settings, it is assumed that all nodes are autonomous and do not depend in any case on other nodes. In this research work, contrarily to this design, we …

Materials And Processes For Printed Electronics: Evaluation Of Gravure Printing In Electronics Manufacture, Erika Hrehorova

Dissertations

The primary goal of printing electronics is to create structures and devices that are functionally similar to conventional electronics, but at greater speed, lower cost and less production complexity. There are advantages and challenging disadvantages of using printing processes to manufacture electronic devices. Printing has been very well optimized for printing visual images that meet the requirements of human eye. However in the production of functional electronic devices, there are more stringent requirements on resolution, registration and quality of printed features and functional layers.

The main goal of this work is to form a starting point to a bigger picture …

Characterization Of Molecular Events Following Heavy Metal Cadmium Exposure: A Cellular Regulatory Symphony In Response To Early Cadmium Insult, Chin-Ju Jean Hsiao

Dissertations

Cadmium, a non-essential toxic heavy metal, has been classified as a human carcinogen and one of the most hazardous substances in our environment. Since it can circulate within the food chain, has a long biological half-life and can bio-accumulate, it has the potential to induce detrimental health effects linked to toxicity, cancer and chronic diseases.

In recent years progress has been made to dissect and understand the molecular mechanisms underlying the effects of cadmium exposure. However, few studies have focused on investigating potential protective and/or defense mechanisms naturally applied by cells upon initial exposure, prior to any damage or toxic …

A Role Of Problem-Solving In Complex Intraverbal Repertoires, Rachael A. Sautter

Dissertations

kinner described intraverbal behavior as verbal behavior with no point-to-point correspondence between the stimulus and the response. This verbal operant encompasses a wide range of response topographies ranging from answering simple questions to complex conversational exchanges. Previous interventions for teaching complex responding to questions about category membership have focused primarily on transfer of stimulus control procedures to teach specific intraverbal responses. These procedures have proven effective at establishing basic intraverbal responses but have consistently produced small and somewhat restricted repertoires. Theoreticians have hypothesized that effective use of problem-solving strategies rather than simple stimulus control may account for the performance of …

Low Jitter Phase-Locked Loop Clock Synthesis With Wide Locking Range, Adnan Gundel

Dissertations

The fast growing demand of wireless and high speed data communications has driven efforts to increase the levels of integration in many communications applications. Phase noise and timing jitter are important design considerations for these communications applications. The desire for highly complex levels of integration using low cost CMOS technologies works against the minimization of timing jitter and phase noise for communications systems which employ a phase-locked loop for frequency and clock synthesis with on-chip VCO. This dictates an integrated CMOS implementation of the VCO with very low phase noise performance. The ring oscillator VCOs based on differential delay cell …

People-Search : Searching For People Sharing Similar Interests From The Web, Quanzhi Li

Dissertations

On the Web, there are limited ways of finding people sharing similar interests or background with a given person. The current methods, such as using regular search engines, are either ineffective or time consuming. In this work, a new approach for searching people sharing similar interests from the Web, called People-Search, is presented. Given a person, to find similar people from the Web, there are two major research issues: person representation and matching persons. In this study, a person representation method which uses a person's website to represent this person's interest and background is proposed. The design of matching process …

Analysis Of Truck Delays At Container Terminal Security Inspection Stations, Dae-Gwun Yoon

Dissertations

After September 11, 2001, special attention has been given to the vulnerability at container transportation to terrorist activities. United States Customs and Border Protection (CBP) has set up inspection stations for containers at seaport terminals to screen containers, but this practice affects the truck turnaround time in the seaport by generating additional processing delays.

This dissertation analyses the additional truck turnaround time incurred at the inspection stations under various levels of security. Queuing models were used to estimate truck delay as containers are inspected at two successive security inspection stages. Each stage may utilize one or more inspection equipment. The …

Long Exposure Point Spread Function Estimation From Solar Adaptive Optics Loop Data, Jose Marino

Dissertations

Adaptive optics (AG) systems provide partial correction to wavefront distortions introduced by the Earth's atmosphere. They have become an essential tool to obtain diffraction-limited observations from ground-based telescopes. However, the AG correction is only partial and post-processing with a good estimate of the point spread function (PSF) is required.

PSF estimates are impossible to measure directly during solar observations due to the lack of point sources in the field-of-view. Moreover, the highly variable day-time seeing conditions require the estimated PSF to be simultaneous with the captured image. A method is presented to estimate the long-exposure PSF of AG-corrected solar observations …

Construction Of Fasr Subsystem Testbed And Application For Solar Burst Trajectories And Rfi Study, Zhiwei Liu

Dissertations

The construction of the Frequency Agile Solar Radiotelescope (FASR) Subsystem Testbed (FST) and observational results are described. Three antennas of Owens Valley Solar Array (OVSA) have been upgraded with newly designed, state of art technology. The 1-9 GHz RF signal from the antenna feed is transmitted via broadband (45 MHz-9.5 GHz) optical fiber links to the control room. The RF is then downconverted to a 500 MHz, single-sideband signal that can be tuned across the 1-9 GHz RF band. The data are sampled with an 8-bit, 1 GHz sampling-rate digitizer, and further saved to a computer hard disk. The full-resolution …

Design And Performance Of Cdma Codes For Multiuser Communications, Radharani Poluri

Availability of these code sets is limited because of their generating kernels. Emerging radio applications like sensor networks or multiple service types in mobile and peer-to-peer communications networks might benefit from flexibilities in code lengths and possible allocation methodologies provided by large set of code libraries.

Walsh codes are linear phase and zero mean with unique number of zero crossings for each sequence within the set. DC sequence is part of the Walsh code set. …

Challenges Of Administering A Sino-U.S. Joint Venture Campus In China, Osman Ozturgut

Dissertations

Abstract With the recent globalization movement and decline in foreign student enrollment in universities in developed countries like the U.S., universities are looking for ways to bring education to the student rather than waiting for students to come for education. Therefore, opening a branch campus abroad and bringing education to the student became an alternative for U.S. universities to bringing students to their campuses. This qualitative study explored the political, economic, socio-cultural, and educational challenges of administering a Sino-U.S. joint-venture campus in the People¿s Republic of China. China American University (CAU) is an educational joint venture between China Investment Company …

E-Portfolios: Their Impact On Preservice Teachers' Self-Directed Learning And Computer Technology Skills, Yufang Carole Huang

An Empirical Study Of Employee Relations And Managerial Malpractice Risks In A Four-Year Public Higher Education System, Robert Lee Brown Edd

Dissertations

Over the last decade, the rapid rise in college tuitions and fees has become a national priority, with congressional committees and scholars interested in solving this persistently stubborn and often intractable problem. Although a number of reasons for this phenomenon have been discussed, one theoretically plausible but untested explanation involves the extent to which campus climate may be empirically linked to the costs of managing various legal claims against the university, including workers' compensation, employment practice, and stress claims. To test the empirical validity of this hypothesis, this study gathered campus climate and claims data from 23 campuses and 25 …

Factors That Motivate Or Discourage Movement Into School Leadership Positions And The Implications For Recruitment Policy And Practice, Ginger Lee Blackmon Edd

Dissertations

Public schools in the United States are facing one of the most extensive transformations in school leadership. Districts face the difficult challenge of recruiting and training school leaders who have the capacity to deal with the growing demands and responsibilities placed on school site administrators. Despite a surplus of people certified for administration, the changing demands of the principal's job precipitated by national reform efforts have left a shortage not only of qualified applicants, but also in the total number of applicants (qualified and unqualified) willing to carry the burden of the job. This study investigated the factors that influence …

Communication And Leadership: Faculty Perceptions Of The Department Chair, Kathleen Czech Edd

Dissertations

With department chairs providing a critical link between faculty and administration, their leadership impacts universities on a broad level. However, chairs often report dissatisfaction with the position and experience rapid turnover. In an effort to help understand the role that communication plays in effective leadership for department chairs, this study provides an empirical test of Gibb's theory of defensive vs. supportive communication. As such, this project investigated the communication and leadership behaviors of university department chairs as evaluated by their faculty members. Specifically, 202 randomly selected faculty members from colleges and universities affiliated with the Council of Independent Colleges, Washington, …

Integrating Total Disability Management In A Climate Of Change: A Case Study, Mary E. Jesko Edd

Dissertations

Integrated disability management (IDM) is a cost-containment strategy increasingly being employed by human resources and risk management departments to address occupational and non-occupational illness and injury in a consistent manner. The goal is to both reduce on-the-job injury and minimize the loss of work time due to injury or illness. Although a large number of organizations have embraced the IDM concept, implementing IDM often is difficult because of the complex array of contracts, policies, procedures, corporate cultures and structures. Although extensive research has examined leaders' influence on change in various types of businesses, to date, research has not specifically explored …

Teachers' Perceptions Of A 360-Degree Feedback Process, Catriona Collins Moran Edd

Dissertations

In recent years, the 360° feedback process, which originated in the business world in the 1980s, has been increasingly used for the purpose of teacher evaluation. When this is done, feedback from peers, parents and students, as well as teacher self-reflection and student achievement data, are used in addition to more traditional evaluation strategies. Despite its growing popularity, however, there have been very few published studies about the impact of the 360° feedback process in the business world and even fewer in the field of education. The overarching purpose of this qualitative study was to discover teachers' perceptions of a …

An Investigation Of The Community-Based English Tutoring Program (Cbet), Barbara J. Pongsrikul Edd

Dissertations

Currently in the California K-12 public schools, approximately 25% (about 1.5 million) of the students know little or no English, and their numbers are increasing. Because of this diverse student population, a research study by the Gevirtz Research Center in 2005 reports that it is necessary to develop educational programs that help language-minority families understand and participate in the school system in ways that will support the academic success of their children. As a result of the Proposition 227 Initiative in California, statewide family literacy programs were established as Community-Based English Tutoring (CBET) programs to provide adult English language instruction …

A Mixed Methods Study On Cbam And The Adoption Of Thin Client Computers By Adolescents, Cynthia Sistek-Chandler Edd

Dissertations

Although stages of change and adoption of innovation dynamics have been examined for adult populations, comparable research for adolescents is limited. Applying a change instrument grounded in Concerns-Based Adoption Model (CBAM) to an adolescent population, this study investigates perceptions of 45 middle school students who used thin client portable computers in a one-to-one program at home and at school for 3 years. A mixed methodology design identified which of the 7 stages of concern students passed through and why some students adopted the innovation more readily than others. The Change Facilitator Stages of Concern Questionnaire, a modified version of CBAM, …

Emerging Elements Of Leadership In A Complex System: A Cognitivist Approach, Kirsten Suzanne Hanson Edd

Dissertations

As our world grows increasingly complicated at an intensified pace, leaders must be facile managers of complexity if organizations and society are to productively and peacefully evolve. Today’s global corporations are microcosms of complexity and have the potential to affect life for almost all other species. However, many organizations have not yet become aware of themselves as “living” and still operate as industrial age institutions with rationalist thinking traditionally dominating management practice. Many factors impact an organization’s overall effectiveness. Yet, executive leaders are seen as having the ability to influence change and play a vital role in helping people navigate …

A Concerns-Based Adoption Model Study Of University Instructors Engaged In Faculty Development For Enhancing Learning With Technology, James W. Julius Edd

Dissertations

For over a decade, theorists have suggested that higher education institutions are in the midst of a shift from an emphasis on student access to instruction to student success in learning. Digital technologies are one “lever” increasingly touted as a means to improve teaching and learning in higher education. Because serious efforts at technology integration not only require competence with the technologies, but also often result in changes to instructional methods, colleges and universities are urged to consider faculty development needs. This study detailed how instructor change unfolded in response to a faculty development program intended to enhance the use …

Validating The Experiences Of Male Mexican American Community College Transfer Students Studying At Catholic Universities, Eliazer Ayala-Austin Edd

Dissertations

California's community colleges and public and private universities must collaborate to address the Tidal Wave II student enrollment surge composed mostly of Hispanic/Latinos and Asian students in order to meet the educational needs of community college transfer students (CCTSs). Avoiding the issue will result in continued neglect of CCTS within public and private institutions; possible outcomes include delayed graduation and potential attrition of at-risk students. Using Rendón's (1994) theory of student validation as the theoretical framework, this qualitative study uncovered the validating and other university experiences of male Mexican American CCTSs. This qualitative study included individual interviews of six CCT …
