Evaluation Of Toxic Cyanobacteria In Central Florida Stormwater Ponds, Robert Miller Jan 2005

Evaluation Of Toxic Cyanobacteria In Central Florida Stormwater Ponds, Robert Miller

Electronic Theses and Dissertations

Algal blooms are a common occurrence in water bodies of all shapes and sizes throughout the United States and countries around the world. The State of Florida is no exception to this phenomenon. Cyanobacteria, or blue-green algae, have proven to be of special concern due to its proliferation and potential to produce toxins that are harmful to humans, livestock and wildlife. A casual drive along the roads and in the neighborhoods of central Florida will confirm algal conditions in many areas. The potential for exposure to harmful and possibly fatal toxins associated with these algal blooms are becoming more evident …

Right Turn Split: A New Design To Alleviate Weaving On Arterial Streets, Khaled Shaaban Jan 2005

Right Turn Split: A New Design To Alleviate Weaving On Arterial Streets, Khaled Shaaban

Electronic Theses and Dissertations

While weaving maneuvers occur on every type of roadway, most studies have focused on freeway maneuvers. Weaving occurring on non-freeway facilities, such as arterial streets, can cause significant operational problems. Arterial streets weaving typically occur when vehicles coming from a side street at an upstream intersection attempt to enter the main street from one side to reach access points on the opposite site at a downstream intersection by crossing one or more lanes. This dissertation investigates the type of problems occurring on arterial streets due to the weaving movements and recommends a new design to alleviate weaving on arterial streets. …

Healing Violence In South Africa: A Textual Reading Of Kentridge's 'Drawings For Projection', Vanessa Thompson Jan 2005

Healing Violence In South Africa: A Textual Reading Of Kentridge's 'Drawings For Projection', Vanessa Thompson

Electronic Theses and Dissertations

While the literature appears to understand trauma and violence as experienced singularly, and as effecting intrapsychic changes or reactions, latterly there has been a recognition that this understanding of the term 'trauma' may not be adequate to describe violence suffered over a prolonged period of time. Further, psychology tends to avert our attention from healing by attending to symptomatology. In South Africa, during the apartheid years (1948-1994), violence was constituted by an extraordinary threat to ongoing being and was informed by a totalitarian prejudice. Creative texts, unlike traumatic texts, show how many artists have worked with South African traumas in …

Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches, Brandon Barton Jan 2005

Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches, Brandon Barton

Electronic Theses and Dissertations

Traditional views of food web dynamics have characterized species interactions as linear and direct. However, modern food web theory suggests that interactions can also be nonlinear and indirect, so that disturbance at one trophic level is transmitted throughout the community. Many previous studies have demonstrated that the removal of top predators from terrestrial ecosystems can have broad-scale impacts on community ecology. I examined the direct and indirect effects of raccoon removal from sea turtle nesting beaches in east-central Florida during the summers of 2003 and 2004. Raccoon and ghost crab predation are among the highest causes of egg mortality for …

Internet Advertising: Are We Breaking Ground Or Moving Dirt?, Jaime Marshall

Electronic Theses and Dissertations

Seeking to validate the Elaboration Likelihood Model (ELM) of Persuasion for the online advertising context, a laboratory experiment utilizing 240 undergraduates was conducted at a southeastern university. The quality of banner advertisement contents--product endorser (spokesperson) and arguments (headlines)--were manipulated testing the variables' effect on click-through and attitude toward the advertisement for groups with high and low levels of product category involvement. Exploring a replica of a popular music website, participants were exposed to the test banners on the site's homepage. Due to the limited number of click-throughs, the relationship between the independent variables and click-through could not be established. However, …

Confocal Laser Scanning Microscopy As A Tool For The Investigation Of Tetracycline Fluorescence In Archaeologicalhuman Bone, Corey Maggiano Jan 2005

Confocal Laser Scanning Microscopy As A Tool For The Investigation Of Tetracycline Fluorescence In Archaeologicalhuman Bone, Corey Maggiano

Electronic Theses and Dissertations

Fluorochromes such as tetracycline have been used to label bone for histomorphometric analysis, measuring bone formation, growth, maintenance, and pathology. More recently, similar fluorescence has been observed in ancient human bone. Attributed to tetracycline (TC) exposure, this phenomenon could affect various aspects of health during life and/or preservation of remains postmortem. Standard epifluorescence microscopy is the most common tool employed in the analysis of these labels. Though valuable, this technique is limited by its inability to penetrate bone three-dimensionally and its inclusion of out-of-focus light, possibly disrupting accurate analysis. Confocal Laser Scanning Microscopy (CLSM) has been demonstrated as a valuable …

Presuppositions In Moral Education Discourse: Developing An Analytic Framework And Applying It To Moral Education Traditions, Maria Sciaino Jan 2005

Presuppositions In Moral Education Discourse: Developing An Analytic Framework And Applying It To Moral Education Traditions, Maria Sciaino

Electronic Theses and Dissertations

Moral education is ever more important in our schools today, but the various moral education traditions make it difficult to decide which tradition best serves our purpose and population. This dissertation develops and uses an original analytic framework to narrow the choices of moral education curricula. The analytic framework introduced presuppositions that expounded upon one's center of value or source of moral authority, the nature of people and their capacity for rational thought, the nature of society, the time orientation of tradition, and the resulting morality in action. The analytic framework was then applied to ten notable traditions: Catholic religious …

How Does The Use Of Picture Books During Instruction Improve Student Word Choice In Writing?, Laurie Anne Mcadams Jan 2005

How Does The Use Of Picture Books During Instruction Improve Student Word Choice In Writing?, Laurie Anne Mcadams

Electronic Theses and Dissertations

The purpose of my research was to determine how the use of picture books during instruction would improve student word choice in writing. Donald Graves (2003), a renowned researcher in the teaching of writing, states, "All children need . . . to be surrounded with poetry, stories, information books, biography, science and history, imaginative and factual books." Graves' research presents successful classroom instruction when teachers incorporate literature as a fundamental part of their reading and writing instruction. Likewise, Susan Anderson McElveen and Connie Campbell Dierking (2000) conducted a study with their students using picture books as "precise examples" to teach …

Time Estimation And Hand Preference, Maria Rodriguez Jan 2005

Time Estimation And Hand Preference, Maria Rodriguez

Electronic Theses and Dissertations

This work examines the effect of participants' gender and handedness on the perception of short intervals of time. The time estimation task consisted of an empty production procedure with forty trials at each of four intervals of one, three, seven, and twenty seconds. The four target intervals represent a natural logarithmic progression and a series that bracket important temporal thresholds. The order of presentation of those intervals was randomized across participants but yoked across the sexes in each of the respective dominant hand groups. The two between-subject factors, with two levels each, were sex and handedness. Participants produced forty estimates …

Design And Assessment Of Compact Optical Systems Towards Special Effects Imaging, Vesselin Chaoulov Jan 2005

Design And Assessment Of Compact Optical Systems Towards Special Effects Imaging, Vesselin Chaoulov

Electronic Theses and Dissertations

A main challenge in the field of special effects is to create special effects in real time in a way that the user can preview the effect before taking the actual picture or movie sequence. There are many techniques currently used to create computer-simulated special effects, however current techniques in computer graphics do not provide the option for the creation of real-time texture synthesis. Thus, while computer graphics is a powerful tool in the field of special effects, it is neither portable nor does it provide work in real-time capabilities. Real-time special effects may, however, be created optically. Such approach …

A Predictive Model For Benchmarking Academic Programs (Pbap) Using U.S. News Ranking Data For Engineering Colleges Offering Graduate Programs, Lisa Gay Marie Chuck Jan 2005

A Predictive Model For Benchmarking Academic Programs (Pbap) Using U.S. News Ranking Data For Engineering Colleges Offering Graduate Programs, Lisa Gay Marie Chuck

Electronic Theses and Dissertations

Improving national ranking is an increasingly important issue for university administrators. While research has been conducted on performance measures in higher education, research designs have lacked a predictive quality. Studies on the U.S. News college rankings have provided insight into the methodology; however, none of them have provided a model to predict what change in variable values would likely cause an institution to improve its standing in the rankings. The purpose of this study was to develop a predictive model for benchmarking academic programs (pBAP) for engineering colleges. The 2005 U.S. News ranking data for graduate engineering programs were used …

Formalization Of Input And Output In Modern Operating Systems: The Hadley Model, Matthew Gerber Jan 2005

Formalization Of Input And Output In Modern Operating Systems: The Hadley Model, Matthew Gerber

Electronic Theses and Dissertations

We present the Hadley model, a formal descriptive model of input and output for modern computer operating systems. Our model is intentionally inspired by the Open Systems Interconnection model of networking; I/O as a process is defined as a set of translations between a set of computer-sensible forms, or layers, of information. To illustrate an initial application domain, we discuss the utility of the Hadley model and a potential associated I/O system as a tool for digital forensic investigators. To illustrate practical uses of the Hadley model we present the Hadley Specification Language, an essentially functional language designed to allow …

Famtile: An Algorithm For Learning High-Level Tactical Behavior From Observation, Brian Stensrud Jan 2005

Famtile: An Algorithm For Learning High-Level Tactical Behavior From Observation, Brian Stensrud

Electronic Theses and Dissertations

This research focuses on the learning of a class of behaviors defined as high-level behaviors. High-level behaviors are defined here as behaviors that can be executed using a sequence of identifiable behaviors. Represented by low-level contexts, these behaviors are known a priori to learning and can be modeled separately by a knowledge engineer. The learning task, which is achieved by observing an expert within simulation, then becomes the identification and representation of the low-level context sequence executed by the expert. To learn this sequence, this research proposes FAMTILE - the Fuzzy ARTMAP / Template-Based Interpretation Learning Engine. This algorithm attempts …

Developing An Object-Oriented Approach For Operations Simulation In Speedes, Amit Wasadikar Jan 2005

Developing An Object-Oriented Approach For Operations Simulation In Speedes, Amit Wasadikar

Electronic Theses and Dissertations

Using simulation techniques, performance of any proposed system can be tested for different scenarios with a generated model. However, it is difficult to rapidly create simulation models that will accurately represent the complexity of the system. In recent years, Object-Oriented Discrete-Event Simulation has emerged as the potential technology to implement rapid simulation schemes. A number of software based on programming languages like C++ and Java are available for carrying out Object Oriented Discrete-Event Simulation. These software packages establish a general framework for simulation in computer programs, but need to be further customized for desired end-use applications. In this thesis, a …
