The Effect Of Cognitive Aging On Multimedia Learning, Boaventura Dacosta
The Effect Of Cognitive Aging On Multimedia Learning, Boaventura Dacosta
Electronic Theses and Dissertations
If not designed in consideration to the workings of the human mind, multimedia learning environments can impose too high a demand on working memory. While such high cognitive load presents challenges for learners of all ages, older learners may be particularly affected as research on cognitive aging has shown the efficiency of working memory declines with age. Research has suggested that cognitive load theory (CLT) and the cognitive theory of multimedia learning (CTML) are likely to accommodate the cognitive needs of older learners; however, few of the principles emerging from these theories have been examined in the context of cognitive …

Integrating Key Elements In An E-Learning Curriculum For An Optimum Educational And Interactive User Experience, Heather Stearns
Integrating Key Elements In An E-Learning Curriculum For An Optimum Educational And Interactive User Experience, Heather Stearns
Electronic Theses and Dissertations
This study determines the particular components that are considered the best practices to use when implementing an e-Learning curriculum. Technical communicators and instructional designers have numerous development options to choose from. However, practices that work in academe do not always integrate well in a corporate setting, and what works for one corporation may not work for another. There is no singular methodology for developers to apply that enables e-Learning to fit every organization's needs. Research shows that to ensure a successful online learning implementation, a sound project management team must be in place at the beginning of the project planning. …

Development And Forensic Application Of Dye Probe Fluorescence Resonance Energy Transfer For Improved Detection Of Changes In Dn, Micah Halpern
Electronic Theses and Dissertations
Discovering, screening, and associating changes in DNA sequence are important to a broad range of disciplines and play a central role in Forensic Science. The typical types of changes include sequence variations [single nucleotide polymorphisms (SNP)] and length variations [short tandem repeats (STR)]. The steps for forensic DNA sample processing are similar for both types of changes but diverge at the point of detection. A number of approaches are being explored for SNP genotyping while STR analysis primarily consists of size-based analysis by capillary electrophoresis. Limitations exist for all current detection methods that pose significant impacts to forensic analysis. Bi-allelic …

Field Of View Effects On Reflexive Motor Response In Flight Simulation, Javier Covelli
Field Of View Effects On Reflexive Motor Response In Flight Simulation, Javier Covelli
Electronic Theses and Dissertations
Virtual Reality (VR) and Augmented Reality (AR) Head Mounted Display (HMD) or Head Worn Display (HWD) technology represents low-cost, wide Field of Regard (FOR), deployable systems when compared to traditional simulation facilities. However, given current technological limitations, HWD flight simulator implementations provide a limited effective Field of View (eFOV) far narrower than the normal human 200[degrees] horizontal and 135[degrees] vertical FOV. Developing a HWD with such a wide FOV is expensive but can increase the aviator's visual stimulus, perception, sense of presence and overall training effectiveness. This research and experimentation test this proposition by manipulating the eFOV of experienced pilots …

Perception And Displays For Teleoperated Robots, Linda Upham Ellis
Electronic Theses and Dissertations
In remote or teleoperational tasks involving humans and robots, various aspects of the remote display system may greatly influence the individual's interactions with the teleoperated entity. This dissertation examined various configurations of display systems on several measures of operator performance, physiological states, and perceptions of the task. Display configurations included altering the camera placement (attached to the robot or placed overhead), screen orientation (horizontal or vertical), and screen size (small or large). Performance was measured in terms of specific task goals, accuracies, strategies, and completion times. Physiological state was assessed through physiological markers of arousal, specifically heart rate and skin …
Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz
Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz
Electronic Theses and Dissertations
Today's best intelligent, adaptive, multimedia trainers have shown excellent performance; however, their results still fall far-short of what good human tutors can achieve. The overarching thesis of this paper is that future intelligent, adaptive systems will be improved by taking into account relevant, consistent, and meaningful individual differences. Specifically, responding to individual differences among trainees will (a) form more accurate individual baselines within a training system, and (b) better inform system responses (so that they interpret and respond to observable data more appropriately). One variable to consider is trait arousability, which describes individual differences in sensitivity to stimuli. Individuals' arousability …
A Comparison Of Computer And Traditional Face-To-Face Classroom Orientation For Beginning Critical Care Nurses, Patricia Anzalone
A Comparison Of Computer And Traditional Face-To-Face Classroom Orientation For Beginning Critical Care Nurses, Patricia Anzalone
Electronic Theses and Dissertations
Purpose: Education of the novice critical care nurse has traditionally been conducted by critical care educators in face-to-face classes in an orientation or internship. A shortage of qualified educators and growth in electronic modes of course delivery has led organizations to explore electronic learning (e-learning) to provide orientation to critical care nursing concepts. Equivalence of e-learning versus traditional critical care orientation has not been studied. The primary aim of this study was to examine the equivalency of knowledge attainment in the cardiovascular module of the Essentials of Critical Care Orientation (ECCO) e-learning program to traditional face-to-face critical care orientation classes …
Am I Too Fat To Be A Princess? Examining The Effects Of Popular Children's Media On Preschoolers' Body Image, Sharon Hayes
Am I Too Fat To Be A Princess? Examining The Effects Of Popular Children's Media On Preschoolers' Body Image, Sharon Hayes
Electronic Theses and Dissertations
The current study investigated the effects of brief exposure to appearance-related media on female preschoolers' body image. Results indicated that exposure did not affect body dissatisfaction or engagement in appearance-related play behaviors. Surprisingly, participants' self-reported frequency of weight concerns decreased at posttest. In contrast to older populations, it is possible that young children may adopt the persona of attractive characters with whom they identify rather than comparing themselves to the characters. This level of identification temporarily may alleviate weight concerns. This is the first empirical study to provide support for previous findings that suggest media exposure does not affect body …
Gamma Hydroxybutyrate Use Among College Students: Application Of A Memory Model To Explore The Influence Of Outcome Expectancies, Pamela Brown
Electronic Theses and Dissertations
Gamma Hydroxybutyrate (GHB) was banned from the consumer market by the Food and Drug Administration in 1991. Despite the ban, use of GHB has continued to contribute to thousands of emergency department visits and numerous fatalities in recent years. Efforts to reduce the use of this drug have had limited impact, which may be the result of using traditional prevention strategies that focus exclusively on educating people about of negative consequences of substance use rather than addressing the factors that motivate use. In an effort to identify motivational factors that could be targeted in future prevention efforts, the present study …
Tactile Working Memory And Multimodal Loading, Peter Terrence
Tactile Working Memory And Multimodal Loading, Peter Terrence
Electronic Theses and Dissertations
This work explored the role of spatial grouping, set size, and stimulus probe modality using a recall task for visual, auditory, and tactile information. The effects of different working memory (WM) loading task modalities were also examined. The Gestalt spatial organizing principle of grouping showed improvements in response times for visual and tactile stimulus probes with large set sizes and apparently allowed participants to effectively chunk the information. This research suggests that tactile information may use spatial characteristics typically associated with visual information, as well as sequential characteristics normally associated with verbal information. Based on these results, a reformulation of …

Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem
Electronic Theses and Dissertations
In combat, soldiers encounter stress from multiple sources including loss of sleep, extremely high levels of physical and psychological discomfort, extended periods of increased vigilance, and intense danger. Therefore, it is imperative to train such personnel on how to cope with these stressors. One way to do this is to include stressors in different forms of training to acclimate soldiers to the subsequent stress of combat. Due to their advantages, tactile trainers are being investigated increasingly for the use of training Army medics in this context. The present work examines how vibrating tactile sensors, or tactors, can be used as …
Green Chairs, Fictional Phalluses, Infiltration, And Love On The Rocks: Medical Imaging Artifacts Blown Up, Lynn Koller
Green Chairs, Fictional Phalluses, Infiltration, And Love On The Rocks: Medical Imaging Artifacts Blown Up, Lynn Koller
Electronic Theses and Dissertations
This text outlines and applies a methodology for deciphering problems and producing new information by analyzing the artifacts produced by medical imaging technologies - text and images - using practices gleaned from Surrealists, semiologists, and visual artists, emphasizing its own form as being the product of the apparatuses that produce it and therefore untrustworthy. Its basic assumption is that every text contains the information necessary to solve problems of all sorts, though because of the limitations of this text in both form and authorial intellect, we may only reach a starting point for a solution herein. In this regard, we …

Emily Mann's play Still Life is a story of a Vietnam War veteran who returns home to a less than enthusiastic welcome. Like most veterans from this war, he struggles to come to terms with the atrocities he witnessed and even carried out himself. The play consists of three characters: Mark, a Vietnam veteran, Cheryl, his wife, and Nadine, his lover. Both women believe they intrinsically understand Mark, but neither truly can. Mark has returned from the war violent, irrevocably broken, and feeling that he has been abandoned by society. Emily Mann interviewed real people and transcribed their words into …
Sexuality And Courtships Of 19th Century Vienna Vs 21st Century America Through The Roles Of Alfred And Sam In Romance, Romance, James Haynie
Electronic Theses and Dissertations
For my thesis, I plan to research the sexuality and the process of courtship, and the differences between 19th century Vienna and modern America, specifically as to how it relates to my characters in Romance, Romance. My interest in the topic springs directly from the script. What I mean is, my initial idea of sexuality of the 19th century is very Victorian and straight-laced, where as I think of modern day as very sexually liberated. However, in the script, the first act, set in Vienna, is much more sexually explicit and active. In fact, the second act is all building …

Turning Tricks And The Modern Female Protagonist: An Analysis Of The Portrayal Of The Role Of The Demimonde From Viennese Operet, Melissa Nay
Electronic Theses and Dissertations
The demimondaine, an exclusive courtesan in nineteenth-century Europe, and the modern mezzo-soprano protagonist are prevalent characters in American musical theatre and can be observed in various styles throughout European music and drama. In Arthur Schnitzler s The Little Comedy, the female protagonist is both a romantic heroine and mistress; and in Jules Renard s Le Pain de Ménage, the lead player is anything but the classic ingénue. In preparation for performance and to further the research in the contemporary music comedy realm, I prepared for the roles of Josefine and Monica in the University of Central Florida s production of …

In addition, I …
The Dark Side Of The Tune: A Study Of Villains, Michael Biggs
The Dark Side Of The Tune: A Study Of Villains, Michael Biggs
Electronic Theses and Dissertations
On championing the villain, there is a naive quality that must be maintained even though the actor has rehearsed his tragic ending several times. There is a subtle difference between to charm and to seduce. The need for fame, glory, power, money, or other objects of affection drives antagonists so blindly that they ve no hope of regaining a consciousness about their actions. If and when they do become aware, they infrequently feel remorse. I captured the essence of the villain by exposing these lightless characters to the sun. On Monday, April 9th and Tuesday, April 17th, 2007, on the …
A Prototype For Narrative-Based Interactivity In Theme Parks, Kirsten Kischuk
A Prototype For Narrative-Based Interactivity In Theme Parks, Kirsten Kischuk
Electronic Theses and Dissertations
The purpose of this thesis is to look at the potential for interactive devices to enhance the story of future theme park attractions. The most common interactive theme park rides are about game-based interaction, competition, and scoring, rather than about story, character, and plot. Research into cognitive science, interactivity, narrative, immersion, user interface, theming and other fields of study illuminated some potentially useful guidelines for creating compelling experiences for park guests. In order to test some of these ideas, an interactive device was constructed and tested with study subjects. Each study subject watched a video recording of an existing theme …

The Effect Of Selective Cholinergic Lesion Of Medial Septum On Recognition Memory, Li Cai
Electronic Theses and Dissertations
The objective of this study was to clarify the role of septal-hippocampal cholinergic neurons in object and spatial recognition memory. Stereotaxic-surgical infusion of the selective cholinergic neurotoxin, 192IgG-saporin (SAP), into the medial septum (MS) of Sprague-Dawley rats was utilized to establish an animal model of cholinergic deficit of the septal-hippocampal tract, which had been expected as a pathologic model of memory impairment for Alzheimer's disease (AD). Three types of recognition memory were examined: retrograde object recognition, anterograde object recognition, and anterograde spatial recognition. These were examined with a modified version of a standard object recognition paradigm. For retrograde memory retention …
Show And Tell: Learning With Interactive Videoconferencing In Kindergarten, Debra Piecka
Show And Tell: Learning With Interactive Videoconferencing In Kindergarten, Debra Piecka
Electronic Theses and Dissertations
The research investigated how kindergartners make meaning using interactive videoconferencing. The study explored two research questions: 1) What types of meanings are being formed by the kindergartners during interactive videoconferences and, 2) What are the nature of young children's emerging inquiries and dialogue surrounding their use of interactive videoconferencing in their classroom? The study embodied a Vygotskian perspective as the theoretical framework in order to meet demands associated with the young participants' vulnerability, developmental appropriateness, and the students' interactive learning environment. Employing an ethnographic, participant observation methodology, the research design was informed by three criteria: 1) a pilot study, 2) …
