Examining Stage Theories And The Predisposition To Lead Within The Homosexual Community, David Robert Blair Edd

Dissertations

An application of homosexual stage-based self-integration theory suggests that until gay individuals have become fully self-integrated, their capacity for leadership within the community is diminished. Unfortunately, now more than ever before, leadership is needed in dealing with such pressing community issues as the disproportionately high suicide rate among gay teens, the ongoing struggle for gays to become fully self-integrated individuals, bringing equal rights to the gay population, and of course, developing a base of strong gay leaders to meet the ongoing challenges facing this population. To test the self-integration-leadership hypothesis, this study surveyed 150 men in gay Internet chat rooms …

Fabricating Freddy Vs. Jason: Understanding A Motion Picture As A Social Encounter Between Fans And Filmmakers, Jason M. Rapelje

Dissertations

The break in the mass communicative chain, which separates producers and receivers from one another in both time and space, impedes researchers from studying motion pictures as social encounters. As with face-to-face encounters, producers and receivers of motion pictures depend upon the use of "rules of relevance" (Goffman, 1961) and "typifactory schemes" (Berger & Luckmann, 1966) for their encounters to take place. I examine the social encounter that takes place between some of the filmmakers and fans of Freddy vs Jason through the use of these concepts, as well as a revision of John B. Thompson's (1990) methodological framework of …

Lightweight Intrusion Detection: A Second Line Of Defense For Unguarded Wireless Sensor Networks, Vijay Subhash Bhuse

Dissertations

Wireless sensor networks (WSN) are formed of stationary nodes with stringent resources (in terms of battery power, processor speed, memory and radio range). They have specific communication and traffic patterns.

Making sensor networks secure is especially challenging because of the wireless medium and the fact that WSN is physically unguarded. The compromise of sensor nodes may lead to the loss of secret information and tampering of the software. Hence, intrusion detection techniques must be designed to detect at least some of the most dangerous attacks. Further, these techniques should be lightweight to suit resource constrained nature of WSN.

We focus …

The Road Between Cemeteries, Richard Paul Foss

Dissertations

The Road Between Cemeteries is a creative dissertation, a book of poems that makes use of many various forms and styles. I am interested in both the lyric andthe narrative traditions and the heart of this collection, I believe, lies in the space between; the narrative is the road, moving inexorably forward, and the lyric,the passenger dreaming, questioning out the window. I am also interested in contemporary relationships, both those of a private nature such as we have with our parents, spouses, children, and those of a public nature, such as with our heroes in literature, sports and music.

Effects Of Detectable Warnings On Individuals With Mobility Impairments, Helen Lee

Dissertations

The Americans with Disabilities Act (ADA) mandates that environmental and architectural barriers, such as curbs, be removed to enableindividuals with disabilities to travel about in the community with increased mobility. While installation of ramps benefit individuals with mobility impairments, the absence of curbs results in the loss of information used by individuals with visual impairments for street detection. As a result, truncated domes detectablewarning surfaces were developed to alert visually impaired travelers of potential hazards and vehicular pathways. Research to date is limited and inconclusive regarding the impact of detectable warning surfaces on individuals with mobility impairments. Further, no research …

Scholarly Art: The Writing Experiences Of Student Affairs Professionals, Wanda L.E. Viento

Dissertations

Special issues of the major student affairs journals recently have reflected on the scholarship of the profession (Blimling, 2001; Roper, 2002). The focus of these recent reflections, as well as prior publications on student affairs scholarship (e.g., Davis & Liddell, 1997; Engstrom, 1999; Hunter, 1986; Hunter & Kuh, 1987), largely has been on mentoring research, describing scholarship trends, critiquing existing patterns, and/or envisioning the shape of future scholarship. While the profession of student affairs acknowledges the critical need to promote scholarship and the dissemination of information, little has actually been done to help people get there. Only a few articles …

When developing methods to teach nurses essential content for combat casualty care, it is important to understand the cognitive and learning processes involved in acquiring that knowledge. Measures to examine how military nurses think and learn have significance, especially when applied to the high-stress, high-stakes practice arena of combat causality care. Use of these measures in evaluating educational strategies will help answer the need for better deployment readiness for military nurses. The purpose of this study is to develop an instrument to …

A Collaborative, Hierarchical, Incremental, And Problem Solving Information Systems Development Model, Timothy Joseph Burns

Dissertations

The "software crisis" has been a much discussed and debated topic in Information Systems research. A core cause of the crisis is often identified as the methodologies and approaches used to develop information systems. Thus, over the years a multitude of methodologies have emerged in support of quality software. While many of these methodologies have been effective, research has shown that system development is a highly circumstantial process, and that no one methodology can be optimal in every context of every project. It is also a fact that system development practitioners have employed ad hoc approaches to modify formal methodologies …

Some Contributions On Mimo Radar, Nikolaus Lehmann

Dissertations

Motivated by recent advances in Multiple Input Multiple Output (MIMO) wireless communications, this dissertation aims at exploring the potential of MIMO approaches in the radar context. In communications, MIMO systems combat the fading effects of the multi-path channel with spatial diversity. Further, the scattering environment can be used by such systems to achieve spatial multiplexing. In radar, a complex target consisting of several scatterers takes the place of the multi-path channel of the communication problem. A target's radar cross section (RCS), which determines the amount of returned power, greatly varies with the considered aspect. Those variations significantly impair the detection …

High Resolution Studies Of Complex Solar Active Regions, Na Deng

Dissertations

Flares and Coronal Mass Ejections (CMEs) are energetic events, which can even impact the near-Earth environment and are the principal source of space weather. Most of them originate in solar active regions. The most violent events are produced in sunspots with a complex magnetic field topology. Studying their morphology and dynamics is helpful in understanding the energy accumulation and release mechanisms for flares and CMEs, which are intriguing problems in solar physics.

Doppler Spread Estimation In Mobile Fading Channels, Hong Zhang

Dissertations

The Doppler spread, or equivalently, the mobile speed, is a measure of the spectral dispersion of a mobile fading channel. Accurate estimation of the mobile speed is important in wireless mobile applications which require such as knowledge of the rate of channel variations. In this dissertation, first the performance of classical crossing- and covariance-based speed estimators is studied. Next, the problem of mobile speed estimation using diversity combining is investigated. Then, a nonparametric estimation technique is proposed that is robust to different channel variations. Finally, cyclostationarity-based speed estimators which can be applied either blindly or with the aid of pilot …

Politics And The Glass Ceiling In American Law Enforcement: Why Not More Women Chiefs Of Police?, Madeline G. Meistrich Edd

Dissertations

Law enforcement is one of the last male-dominated occupations. Out of 18,000 police departments in the United States, only 200 to 250 have women chiefs. Such under-representation reflects the "glass ceiling" effect of a gender-based metaphorical barrier that prevents women from rising to the top of an organization, regardless of qualifications. The research examined three questions: what are the issues and problems articulated by women officers attempting to move upwards; what strategies were employed as they attempted to advance; and what strategies could help other women reach the top? Nine female primary participants in law enforcement leadership were interviewed, as …

Pedagogy In Online Graduate Business Learning Environments, Alicia Maria Gallegos Butters Edd

Dissertations

Many higher education institutions have decided to offer graduate business online courses and full degree online programs. Offering a quality education for graduate business students online is of concern to business school professors, administrators, and students. Instructors are concerned with the content, delivery method, and level of student achievement. Instructional design support for the online instructors is often lacking in the online curriculum and pedagogy, leaving the faculty with a great deal of freedom to create their own course content, structure, and delivery without any formal distance education training. For this reason, it is imperative for universities to establish online …

Wherry Revisited: An Empirical Examination Of The Nonperformance Factors That Influence Variation In A Performance Rating, Raymond B. Roll Edd

Dissertations

In a perfect performance rating system, both the recall and rating of an individual's behavior would precisely mirror the performance of that ratee. However, the reality of performance rating systems is that often times the rater's recall and subsequent rating fails to reflect the true performance of the individual. The difference between actual and perceived performance has been attributed in the literature to conscious or unconscious rater bias. In 1952, Wherry developed a rating theory based on a series of mathematical equations that precisely defined the relationship between the performance of the ratee and the recall of that observation. Key …
