Title: THE EFFECT OF STIMULUS DEVIANCE ON THE HUMAN EVOKED POTENTIAL.
Creator: PERALME, LYNNE., Florida Atlantic University
Abstract/Description: The orienting response is hypothesized by Sokolov (1963, 1969) to be monotonically related to the magnitude of stimulus change and independent of the direction of change. These parameters were simultaneously manipulated in the present study along the dimension of stimulus frequency. The intermediate repetitive standard stimulus was a 1000 Hz tone and the infrequent deviant stimuli were 950, 975, 1025 and 1050 Hz tones. The component of the human evoked potential found to be the most sensitive...
Show moreThe orienting response is hypothesized by Sokolov (1963, 1969) to be monotonically related to the magnitude of stimulus change and independent of the direction of change. These parameters were simultaneously manipulated in the present study along the dimension of stimulus frequency. The intermediate repetitive standard stimulus was a 1000 Hz tone and the infrequent deviant stimuli were 950, 975, 1025 and 1050 Hz tones. The component of the human evoked potential found to be the most sensitive to stimulus deviance was the P3. Consistent with Sokolovian theory, P3 amplitude displayed a U-shaped function in which the extreme deviants produced the largest P3s, proximate deviants produced intermediate P3s and the repetitive standard produced the smallest P3s.

Title: Endogenous programs and the development of sea-finding orientation of loggerhead hatchlings (Caretta caretta).
Creator: Barrett, Christie A., Florida Atlantic University, Salmon, Michael
Abstract/Description: This study's objective was to determine if the transfer of a crawling direction to a magnetic compass in loggerhead hatchling sea turtles ( Caretta caretta L.) was facilitated by how long the turtle crawled (an "endogenous timing" component). I first determined how long it took hatchlings to crawl from their nest to the ocean. Two types of experiments were then carried out. In the first, crawling time varied. In the second, both crawling time and direction varied. I found that at most beaches...
Show moreThis study's objective was to determine if the transfer of a crawling direction to a magnetic compass in loggerhead hatchling sea turtles ( Caretta caretta L.) was facilitated by how long the turtle crawled (an "endogenous timing" component). I first determined how long it took hatchlings to crawl from their nest to the ocean. Two types of experiments were then carried out. In the first, crawling time varied. In the second, both crawling time and direction varied. I found that at most beaches hatchlings crawled to the ocean in less than 5 min. My experiments showed that if crawls are too short (1 min), or too long (5 min), vector transfer is weakened compared to a 2 min crawl. I also found that a period of non-directional crawling interfered with the ability of a 2 min crawl to promote calibration. These results confirm that efficient transfer of a crawling vector, maintained by visual compass, to a swimming vector, maintained by a magnetic compass, depends upon an endogenous timing program in hatchlings. The temporal properties of that program are, in turn, apparently shaped by where their mothers place nests on the beach.

All the different methodologies have different approaches for modeling use cases and applying them to other object-oriented models. Use case models help the analyst to construct dynamic as well as static models. In this thesis, we show an approach of modeling use cases for object-oriented software analysis. We give emphasis to modeling the sequences of the activities within the scenarios and the sequences of the scenarios throughout the system. We show how these sequences influence the static model (object diagram) and dynamic model (state diagram). We propose an Integrated State diagram for dynamic modeling and an Object Interaction diagram for modeling the flows of the scenarios throughout the system by applying the use case sequence models. Our approaches are demonstrated by solving a variety of examples.

Show moreBelly dancing is often believed to be a traditional Middle Eastern dance. Belly dance, though, developed in America and only recently appeared in the Middle East. The similarities between traditional women's dances in the Middle East and belly dance are minimal, but representations influenced by the concept of Orientalism have affected our perception of what we accept as Middle Eastern traditions. The concept of Orientalism holds that certain items are selectively chosen or formulated to depict Middle Eastern culture. Representations inspired by Orientalism do not rely on unbiased and truthful portrayals, but rather exaggerate or amplify particular cultural aspects to fashion an image of the Middle East that fits with carefully crafted Western expectations, resulting in stereotypes. Within such an environment, the ideas and beliefs that permitted the fantasy of belly dance as a expression of Middle Eastern culture grew and flourished to create the current attitudes about belly dancing.

Title: ALTERNATIVE SPATIAL FRAMES OF REFERENCE IN THE RECOGNITION OF NOVEL FORMS.
Creator: SULLIVAN, MARY., Florida Atlantic University
Abstract/Description: The effects of retinal and objective orientation on recognition of novel stimuli were examined in a two-phase experiment. In Phase 1 novel stimuli were presented to tilted subjects placed in either an intentional learning condition (they were instructed to remember the stimuli) or an incidental learning condition (they received no instruction regarding memory). In Phase 2 the same stimuli were randomly mixed with distractor stimuli in a recognition test. Stimuli were presented to upright...

In Phase 1 novel stimuli were presented to tilted subjects placed in either an intentional learning condition (they were instructed to remember the stimuli) or an incidental learning condition (they received no instruction regarding memory). In Phase 2 the same stimuli were randomly mixed with distractor stimuli in a recognition test. Stimuli were presented to upright subjects in either their objectively upright orientation (the same orientation relative to gravity as in Phase 1) or their retinally upright orientation (the same orientation relative to subjects' tilted retinas as in Phase 1). The instructions produced no effect on recognition. Evidence that both retinal and objective orientation influenced recognition was obtained in both conditions. Alternative interpretations hypothesized that: (1) dual memory representations of Phase 1 stimuli, referenced to both retinal and objective upright, were formed and (2) a single memory representation of Phase 1 stimuli, referenced to an axis intermediate to retinal and objective upright, was formed.

Title: THE "OBLIQUE EFFECT" IN THE SPATIAL REPRESENTATION OF CHILDREN FOR THE HORIZONTAL AND VERTICAL PLANE.
Creator: HILTON, THOMAS FREDERICK, Florida Atlantic University
Abstract/Description: The effect of stimulus plane orientation (horizontal vs vertical) on mirror-image oblique discrimination was investigated for children 5 to 8 years of age. A significant difference in learning rate favoring the vertical plane presentation was obtained. Tracing the stimuli had no effect on learning rate in either the horizontal or vertical plane. The results were explained in terms of egocentricity in the child's representation of spatial relations.

Title: Sun compass orientation in juvenile green sea turtles (Chelonia mydas).
Creator: Mott, Cody Robert., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Recent studies show that sea turtles use both magnetic and visual cues to successfully orient. Juvenile green sea turtles from the near shore reefs of Palm Beach County, Florida were brought to the lab to determine whether the sun could serve as a visual orientation cue. When tethered during the day in a large outdoor tank west of the ocean, the turtles oriented east to northeast.

Juvenile green sea turtles from the near shore reefs of Palm Beach County, Florida were brought to the lab to determine whether the sun could serve as a visual orientation cue. When tethered during the day in a large outdoor tank west of the ocean, the turtles oriented east to northeast. To determine whether the sun's position was used to maintain their heading, I altered the turtles' perception of time by entraining them to a light cycle advanced by 7 h relative to the natural cycle. When tested afterward in the same outdoor tank the turtles oriented northwest, the predicted direction after compensating for the sun's movement over 7 h across the sky. Orientation was unchanged when the turtles bore magnets that negated the use of magnetic cues. These results are consistent with the hypothesis that the turtles used the sun for orientation.

This thesis will provide an object-oriented model of a MRP system which was created and presented by using the Object Modeling Technique (OMT). The model consisted of three parts, the object model, dynamic model, and functional model. An innovative way to handle the static bill of materials (BOM) data with a more flexible dynamic item class was developed. To demonstrate the flexibility, extendability, and reusability of the object-oriented MRP model, two major business change scenarios were applied to the model. Minor changes to the design were required to accommodate major changes on the functionality of the MRP system.

Show moreSince the publication of the book Design Patterns: Elements of Reusable Object-Oriented Software by the Eric Gamma, Richard Helm, Ralph Johnson, and John Vlissides, there has been substantial interest in design patterns in the software engineering community. One of the goals of design patterns is to capture design expertise developed by some of the most experienced developers so that it can be reused even by less experienced programmers. Like other engineering disciplines, the authors presented their materials using a catalog format. That format can present problems for students and practitioners. As an alternative, we suggest to first replace the text-based description with a web-based description to make it easier to browse through the information. Second, we suggest using more graphical design representations for pattern descriptions to reduce the amount of necessary textual details. Using the process of reverse engineering, we recreate the original design representations of various pattern implementations. Third, we provide additional graphical representations to relate the general pattern description to specific implementations. Finally, we provide a web-based prototype of the new representation and shows how a user can take advantage of such representations.

Show moreHatchling loggerhead sea turtles emerge from their nests on oceanic beaches, crawl to the surf zone, and swim out to sea. How do turtles maintain oriented headings once they lose contact with land? I tested the hypothesis that by swimming into surface waves hatchlings establish an offshore heading (directional preference), and that once out to sea this heading is transferred to, and maintained by, a magnetic compass. This hypothesis was supported by laboratory and field experiments, described herein. A directional preference can also be established by oriented crawling (from the nest to the surf zone). Thus hatchlings possess two mechanisms (crawling and swimming) for the establishment of an offshore heading. The use of these alternative mechanisms probably assures that turtles escape from shore under the broad range of conditions which they naturally encounter after emerging from their nests.

For the purpose of assessing the approaches, a simple engineering application was selected for object-oriented analysis using the three techniques. The utility of each technique was compared on the basis of complexity, extensibility and reusability. While the approaches aim to provide reusable user interface components and extensibility through incorporation of an additional class, only MVC++ and PAC truly achieve this goal, although at the expense of introducing additional messaging complexity. It was also noted that, in general, decoupling of the GUI classes, while providing increased extensibility and reusability, increases the inter-object messaging requirement.

In this study, I determined how offshore orientation and shallow-water predation rates varied under natural (sand bottom and patch reef) and modified (submerged breakwater and open-beach hatchery) ecological circumstances. Hatchling offshore orientation in the sea was normal under all conditions; there were no significant differences in either scatter or direction among groups. However, predators (tarpon, snapper, barracuda, jacks, and grouper) took more hatchlings as they swam over submerged reefs, and after they entered the water in front of hatcheries. Predators were concentrated at both of these sites probably because prey (small fishes and invertebrates at patch reefs and turtles entering the water where nests were concentrated in hatcheries) occur in greater abundance.

On the other hand, lack of formal semantics for the modeling notation can severely limit the utility of OOMs. Formal specification techniques (FSTs) support the creation of precise and analyzable specifications, but they can be tedious to create and difficult to read, especially by system developers not trained in formal methods. The complementary strengths of OOMs and FSTs suggest that their integration can result in techniques that can be used to create precise and analyzable models. This thesis describes a technique for integrating analysis level UML (Unified Modeling Language) Class Diagrams with the formal notation Object-Z.

Show moreMost popular object-oriented modeling techniques (OOMTs) provide good support for the creation of conceptual models of system behavior and structure. A serious drawback of these techniques is that the concepts and notations used are not rigorously defined. This can lead to the creation of ambiguous models, and to disagreements over the proper use and interpretation of modeling constructs. An important modeling construct that is often loosely defined is aggregation. This thesis presents a precise characterization of aggregation that can help developers identify appropriate applications of the concept. Our characterization is the result of careful analysis of literature on conceptual modeling, knowledge representation and object-oriented (OO) modeling. We discuss primary and secondary properties of aggregation and propose annotations for UML (Unified Modeling Language). An extensive discussion of the more useful patterns of aggregation helps developers pick a suitable prescription of aggregation.

Show moreRock's procedure for separating the effect of objective and retinal spatial reference by varying stimulus orientation and body posture was used in conjunction with the "same-different" reaction time paradigm. It was predicted that the individual differences in perceptual processing (analytic and structural) obtained by Hock (1973) would involve different determinants of spatial reference, these being retinal reference for analytic processing and objective reference for structural processing. The results show that analytic subjects as hypothesized, referenced perceptual information to a retinal coordinate system. Structural subjects however, seemed to reference perceptual information to both objective and retinal coordinates. The results for structural subjects were attributed to the unexpected finding that subjects who were structural while upright, became analytic when in a reclining position. The latter finding suggested that Rock's methodology for separating the effects of retinal and objective orientation relies on the subjects employing the same mode of processing in all bodily postures.
