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 …

Late Pleistocene Climate Variability And Chemical Weathering In The Goriganga, Higher Central Himalaya, North India, Steven Paul Beukema

Dissertations

Relict lacustrine deposits in the Higher Central Himalaya, India, provide a rich repository of paleoclimate information for the period 16 ka to 11 ka. Stable isotope analysis of deposits near the village of Burfu shows the hydrologic balance between glacial meltwater and monsoon precipitation as source waters for the lake. During the period from 15.5 ka to 14 ka the Burfu lake was largely fed by melting glaciers. A warming event correlated to glacial Meltwater Pulse 1a indicates a sudden increase in carbonate weathering in the region accompanied by a gradual decrease in the ratio of glacial meltwater/monsoon precipitation feeding …

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 High School Play, Kevin Drzakowski

Dissertations

The High School Play is a creative work, a full-length play in three acts. Set in suburban Richard M. Nixon High School, the play explores the notion o f adolescent identity while satirizing the American educational system’s artificial construction o f these identities. The play is especially concerned with theatrically representing the way students view each other through flawed frameworks based on preconceived notions o f race, gender, sexuality, and intelligence, as well as how this behavior shapes adolescents’ construction o f their own self-conceptions. The High School Play also deals with the difficulty schools experience in addressing the increasingly …

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 …

Numerical Study Of Flow In Three-Dimensional Fiber Networks And Sedimentation Of Curved Fiber By Lattice Boltzmann Method, Xiaoying Rong

Dissertations

Fiber network is modeled as a three-dimensional random cylindrical fiber network. Nonlinear behavior of fluid flowing through the fiber network is numerically simulated by using the lattice Boltzmann (LB) method. Nonlinear relationship between the friction factor and the modified Reynolds number is simulated and analyzed by using the Fochheimer equation, which includes the quadratic term of velocity. There is a transition from linear to nonlinear region when the Reynolds numbers are sufficiently high, reflecting the inertial effect of the flows. The simulated permeability of such fiber network is compared to the experimental results and the finite element simulations.

A Comparative Study Of Learning Styles And Job Satisfaction To Medical Specialty Chosen Among Physician Assistant Graduates, Eric H. Vangsnes

Dissertations

Since the mid-1980s, a trend has developed whereby Physician Assistants (PAs) are making a transition into medical and surgical specialties (Hooker, 1992). In 1984, 18% of PAs worked in medical and surgical specialties; by 1991, this proportion had risen to 22%; and by 2006, 43% of all PAs worked in medical and surgical specialties ( American Academy of Physician Assistants (AAPA) Census Data 2006 , 2007; Hooker, 1992). One development that may have increased the number of PAs entering specialties was the creation of post-graduate residency programs.

This research examined possible associations between learning style and medical specialty, medical specialty …

Democracy On Stilts: Bolivia’S Democracy From Stability To Crisis, Miguel Centellas

Dissertations

Bolivia’s recent political crisis starkly contrasts to the preceding two decades of relative democratic stability. Though a unique system of “parliamentarized” presidentialism together with lingering consensus on the national project inherited from the 1952 Revolution supported democratic stability, using qualitative and quantitative methods, this study shows that seemingly benign changes in institutional design made in the 1990s contributed to the acceleration of already existing tendencies towards divisive sectoral, regional, and ethnic politics. A key observation is that successful long-term democratization requires institutions for adequately channeling and representing social demands as well as a shared vision of a political “imagined community” …

The Effects Of Post-Secondary Education On State Troopers’ Job Performance, Stress Levels, And Authoritarian Attitudes, Carl J. Lafata

Dissertations

This study was designed to determine the effects of post-secondary education on police officers' job performance, stress levels, and levels of authoritarianism as measured by Altemeyer's (1996) Right-Wing Authoritarianism Scale questionnaire. It involved the analysis of data voluntarily and anonymously submitted via an internet-based survey by 356 of the Michigan State Police's approximately 1,800 enlisted members (those members who are state-certified police officers), along with information collected from informal personal interviews held with a select group of seven of the department's senior leaders. Subsequent analysis of the collected quantitative data revealed no statistical support for the project's first two hypotheses, …

Fluency In Pigeons: The Effects Of Response Rate On Learning, Matthew L. Porritt

Dissertations

Instructional procedures that build high response rates are purported to have significant benefits over procedures that do not focus on fast responding (Binder, 1996). However, much of the research exploring rate-building procedures is confounded by two variables: rate of reinforcement and number of exposures (Doughty, Chase, & O'Shields, 2004). In six experiments, the present study examined the effects of three variables, rate of reinforcement, number of exposures, and rate of responding, on learning under rate-building procedures in pigeons. In Experiment 1, rate-building produced significantly better learning outcomes when compared to a rate-controlled condition with number of exposures held constant. In …

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 …

The Association Between School Choice And School Climate: Comparing School Climate In Private Relgious, Charter, And Public Schools, Mark Krommendyk

Dissertations

The association between school climate and school choice was examined by conducting discriminant function analyses on data gathered from the 1999-2000 Schools and Staffing Survey. This study asked the question, "Does school climate in private religious, charter, and public schools differ?" Teacher and principal responses to survey questions were grouped to measure six characteristics of school climate. The school climate characteristics measured were: (1) supportive principal leadership, (2) teacher collegiality, (3) teacher-principal relationships, (4) teacher satisfaction, (5) student behavior, and (6) teacher empowerment. The study found that the school climate in private religious schools could be statistically distinguished from the …

Autobiography As Counter-Narrative: An Empirical Study Of How Race Enters And Structures The Stories Of Our Lives, Wendy B. Yanow

Dissertations

The primary purpose of this study was to learn about how race enters and then structures the narratives of our life experiences. Critical Race Theory (CRT) was used as a lens through which to examine learning autobiographies and the CRT methodology of counter-storytelling was used to illustrate the ways in which race enters and structures the stories of our lives.

The data consist of personal narratives written by adult students who were not asked to consider their life experiences from a racialized perspective. That resulted in a level of authenticity of their voices. Analyzing the learning autobiographies through a CRT …

The US Navy responded through Operation Unified Assistance (OUA). In a historic first on the hospital ship USNS MERCY, the U.S. Navy deployed one team with members from the Navy, the U.S Public Health Service, a non-government organization (NGO), and a civilian mariner crew to provide humanitarian aid. Despite these efforts, there is a dearth of scholarly research work published on nurses' experiences during the disaster. The purpose …

What’S So Hard About Algebra? A Grounded Theory Study Of Adult Algebra Learners, Michael Steele Reese Edd

Dissertations

In California community colleges, fewer than half of students who enroll in basic algebra courses finish with a grade of C or better. Such a low success rate creates an intense demand on institutional resources, including faculty efforts, tutorial services, classroom availability, and financial aid. Furthermore, students who do poorly in algebra also tend to struggle in other quantitative courses. While research suggests that child algebra learners tend to exhibit specific misconceptions, not much is known about misconceptions held by adult algebra learners. Research does indicate, however, that certain general learning characteristics are common among adult learners. The present study …

In the course of caring for military and civilian combat casualties, military nurses must make rapid, accurate decisions. 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 …
