The purpose of this study was to examine factors that relate to the delivery of mental health services by school psychologists using a national database. The relationship between school psychologists' demographic, preparation, and professional context factors (e.g., gender, ethnicity, educational level, percentage of minority students served, years of experience, and students to school psychologist ratio), and the types of mental health services delivered, amount of time invested in such services, and the desirability of school psychologists to provide or not to provide mental health services was addressed. In addition, the percentages of school psychologists who deliver mental health services and the amount of time they spend in broadly defined mental health service types was addressed. Results of the analyses suggest that students to school psychologist ratio, gender, and percentage of minority students served significantly predict the types of mental health services delivered by school psychologists. In addition, students to school psychologist ratio was related to the amount of time school psychologists spend providing consultation, assessment, and intervention services related to mental health. There was a statistical significant difference in the desire to provide or not to provide more mental health services for male and female psychologists and psychologists with different educational levels. Inaddition, school psychologists' years of experience were related to their desire to provide or not to provide more mental health services. On average, school psychologists in this sample provided seven types of mental health services weekly and provided approximately 29 hours of service related to mental health per week. These results provide initial information as to what factors support school psychologists providing mental health services in schools. This information is important for training programs and legislation to ensure that students are receiving optimal mental health services in schools.

This thesis consists of the two opening chapters of American Odyssey, a nouveau plantation novel that has its roots in two American fiction traditions---the nineteenth-century plantation novel and the twentieth-century neo-slave narrative. It is 1855 and Charles DeCoeur's only motivation to remain Riverwood's owner and master is that his widowed mother and sickly sister rely on the profits of the estate. Charles chafes under the responsibility and physicality of plantation life, unable to reconcile himself to the role of master of a cotton estate in the forgotten heart of East Florida. Then a female Negro, Hellcat, wanders onto the Riverwood estate. Attracted to the woman's unusual appearance and disposition, Charles readily claims her as his property. It is not long before Charles channels his ennui into a renewed interest in Riverwood's workings, a thinly-veiled attempt to hide his growing obsession with the mysterious slave woman. However, tensions are mounting all around Charles. The estate is approaching bankruptcy, the overseer and slaves believe Hellcat has dark intentions, and Charles' mother believes the slave is a bastard child from her husband's scandalous past. But Charles refuses to listen to those around him and continues to let his desires guide his actions, while Hellcat's presence at Riverwood opens new wounds that threaten everyone around her.

NADH:Cytochrome b5 Reductase (cb5r) catalyzes the two electron reduction of the iron center of the heme cofactor found within cytochrome b5 (cb5) utilizing reducing equivalents of the nicotinamide adenine dinucleotide (NADH) coenzyme. Cb5r is characterized by two domains necessary for proper enzyme function: a flavin-binding domain and a pyridine nucleotide-binding domain. Within these domains are highly conserved "motifs" necessary for the proper binding and orientation of both the NADH coenzyme and the FAD cofactor. To address the importance of these conserved motifs site-directed mutagenesis was utilized to generate a series of variants upon residues found within the motifs to allow for the full characterizations. Second, naturally occurring recessive congenital methemoglobinemia (RCM) mutants that are found within or in close proximity to these highly conserved motifs were analyzed utilizing site-directed mutagenesis. The flavin-binding motif "91RxYSTxxSN97" was characterized by the generation of variants T94H, T94G, T94P, P95I, V96S, and S97N. In addition to this, the naturally occurring double mutant P92H/E255- was fully characterized to establish a role of the P92 residue giving rise to RCM. The role of the "124GRxxST127" was determined by the introduction of a positive charge, charge reversal, and conserved amino acid mutations through site-directed mutagenesis of the G124, K125, and M126 residues. Based on the data presented here, each of the residues of the GRxxST motif are directly involved in maintaining the proper binding and orientation of the cb5r flavin prosthetic group. Analysis of the NADH-binding motif "273CGxxx-M278" was accomplished through the characterization of the type II RCM variant M272- and the type I RCM variant P275L. This demonstrates that the deletion of the M272 residue causes a frame shift leading to the inability of the NADH substrate to bind. The introduction of the P275L variant showed that substrate affinity was diminished, yet turnover was comparable to wild-type cytochrome b5 reductase, indicating that although P275 is required for proper substrate binding it is not essential for overall catalytic function. Finally, analysis of the naturally occurring double mutant G75S/V252M provided the first insight into a methemoglobinemia variant that possessed mutations in both the FAD-binding and NADH-binding domains.

This dissertation investigated the area social predictors of health (ASPoH) and Black-White disparities in stroke mortality relationship. Utilizing stroke mortality data obtained from the Florida Department of Health for years 1998-2002, and social and economic data obtained from the year 2000 Census of Population, this study examined the effect of resource availability at the census tract level on Black-White disparities in stroke mortality. The influence of social class on Black-White disparities in stroke mortality and effect modification by social class of the association between Black-White disparities and ASPoH variables was also investigated. Principal component analysis produced four ASPoH scores from economic and social measures. Multiple regression analysis assessed the predictive ability of these ASPoH variables on Black-White disparities. Increases in the female Black-White ratio were significantly associated with increases in the magnitude of the ASPoH-1 and ASPoH-2 variables. When regression analyses were restricted (in terms of population count minimums) to a subset of census tracts, increases in the ASPoH-1 and ASPoH-2 variables were significantly associated with increases in all Black-White disparity measures for both males and females. Assessment of the influence of social class on Black-White disparities in stroke mortality was only feasible at the state level due to a lack of data at the census tract level. With the exception of the 65+ years age-group, Black males and females experienced higher age-group specific stroke mortality rates across each of the social class groups. Inconsistent with previous research findings, Black residents who attained a high school degree had the highest stroke death rates compared to all other educational attainment groups. In the assessment of social class as a potential effect modifier, the study hypothesis stated that the ASPoH measures would have the greatest impact on those residents in the lowest social class category. This predicted effect was only supported when the Male Black-White ratio disparity score was examined. Study findings support the conjecture that unknown and unmeasured processes influence the association between area social predictors and stroke mortality for Black Floridians. Identification of modifiable societal characteristics may be the key to unlocking the foundation of disparities in health outcomes.

In this dissertation, it is my intention to show how Stephen King transcends genre, creates and maintains a viable Secondary Reality, and treats capably those literary techniques that critics expect of a serious writer. In addition, I will discuss the ways in which King has secured the loyalty of his Constant Reader. The primary means of my analysis will be through a close reading of the "expanded and uncut" version of The Stand, one of the classics in King's arsenal. I will begin with an overview of the general set-up in the novel---the start in Arnette, Texas, the actions of the military and media, and the 99.4% communicability of the flu itself. From there, I will delve into detailed character analyses of the main players in the story, before moving on to questions of the bigger picture---good vs evil, the question of choice, the Stand itself, the issue of government, and the promise of the future. I will conclude with a brief look at King's style and consider the overall reasons for his popular appeal. It is my hope that such a lengthy look at one of King's novels---instead of the brief chapters devoted to each of his novels in turn---will reveal not only the reasons why King is worthy of serious study, but will show that King's work does stand up to in-depth criticism, thereby answering one of the key questions of current King scholarship: is there enough in King to work with? Everybody agrees that King can crank out lengthy novels without much trouble; it is my intention to peak [sic] into the corners and down into the basement, if for no other reason than to find out if there really is a bogeyman hiding in there, or if it is merely an over-inflated rag doll of fandom. Either way, whether the horror be in the text or in the lack of substance in the text, I hope that my examination will lend new insight to the study of The Stand, and perhaps pave the way for other in-depth studies of other King novels.

'Clear speech' is a speaking style that talkers often employ when they know they may have trouble being understood, as when speaking in noise or to a person with a hearing loss. When 'clear speech' produced by native talkers is presented in noise to native listeners, it has been shown to be about 10-15 percentage points more intelligible, on average, than normally produced speech. Recent research has shown that bilingual listeners may experience a smaller intelligibility benefit than monolingual listeners from 'clear speech' produced by monolingual talkers. The present study compares the ability of monolingual and bilingual talkers to produce this clear speech intelligibility benefit. The present study investigates the hypothesis that bilinguals may produce a smaller intelligibility benefit than monolinguals when asked to speak clearly. Three groups of talkers were recorded: 13 monolingual native English speakers, 22 'early' Spanish-English bilinguals, with an age of onset of learning English (AOL) of 12 or earlier, and 14 later Spanish-English bilinguals, with an AOL of 15 or later. Talkers produced the target words "bead, bid, bayed, bed, bad" and "bod" in both clear and conversational speech styles. Two repetitions of each word were mixed with noise and presented to monolingual English-speaking listeners across two days of testing. Both monolingual and early bilingual talkers showed a similar degree of clear speech benefit in noise (about 5.5%). Later bilinguals were the least intelligible overall and showed a smaller overall clear speech benefit in noise. Surprisingly, early bilinguals were significantly more intelligible than monolinguals in both speaking conditions (by about 6.5%). For the later bilinguals only, performance was significantly worse for one target word ("bid") in the clear speech condition than in the normal speech condition. These data suggest that later bilinguals, but not early bilinguals, may experience a relative disadvantage when speaking in noise, due to a reduced ability to improve intelligibility by speaking more clearly. Therefore, these persons may benefit from communication strategies or accent reduction programs designed to increase their ability to make themselves understood in difficult speaking environments.

Zinc oxide is a very versatile material that can be used in many microsystems and MEMS applications. ZnO thin film has been utilized in a wide variety of MEMS devices because of its unique piezoelectric, optical, and electrical properties. In particular, piezoelectric property of ZnO can be used in numerous applications from resonators and filters to mass sensors and micro-actuators (e.g., micro-valve and micro-pump). Because of its versatility, this research was focused on analyzing some key properties of ZnO thin film achieved by two different deposition techniques, Pulsed Laser Deposition (PLD) and Sputtering. Multiple experiments were conducted in order to identify the best conditions for the growth of ZnO thin film. Under the optimum conditions, the ZnO thin films will provide the best piezoelectric performance in devices such as microcantilevers. In order to find the best deposition conditions in both PLD and Sputtering multiple depositions have been done and then analyzed using the XRD, AFM, FTIR, nanoindenter, and ellipsometer. For the PLD the best conditions were found to be at 200°C with a partial pressure of O2 of 100 millitorr. For the sputtering system the best film formed when the substrate temperature was kept at 400°C along with RF power of 250 Watts, and a flow rate of 25% O2 and 75% Ar. Both experiments were similar in the fact that both a certain amount of O2 in the chamber and an elevated temperature are needed to facilitate the formation of ZnO crystal structure.

Unmanned aerial vehicles and unmanned ground vehicles, or UAVs and UGVs respectively, currently perform a large variety of missions usually centered around reconnaissance. Because the platforms may vary for a particular type of mission--everything from small unmanned airplanes and remote control vehicles to large vehicles such as the Yamaha R-MAX helicopter and Hummer--flight and navigation controllers must be changed to allow proper control of the selected platform. Currently, controllers are designed and tested in MATLAB/SIMULINK, but then rewritten in C or Assembly for a specific target platform. When designing controllers in a programming language, changes are often tedious, so producing a working controller takes considerable time. MATLAB/SIMULINK provides a GUI interface and SIMULINK provides excellent testing capabilities, so changes may be quick and easy. However, no automated method for converting a simple controller, such as a PID for example, from MATLAB to implementation on a microcontroller has been presented in literature. To implement current in-house controllers designed in MATLAB/SIMULINK, a system consisting of Real-Time Workshop and a C compiler has been used to produce assembly code for a target microcontroller. To aid in verification of the controllers and C code produced by Real-Time Workshop targeted toward aerial platforms, an interface for the controllers in SIMULINK and a flight simulator (X-Plane) has been created. Thus the overall system allows for rapid changes and implementation on a variety of platforms as well as plug-in/plug-out capabilities in the field for diverse missions. Functionality and diversity of the system is demonstrated through testing of PID VTOL controllers in SIMULINK with X-Plane as well as implementation of UGV controllers onboard a small radio controlled truck.

A GIS-based study was undertaken comparing wetland coverages in 1926 and 1999 in selected sub-basins within Pinellas County, Florida, one of the most highly urbanized counties in south-central Florida with almost 50% of the existing land area developed into industrial, commercial or residential land uses (Pinellas County Planning Department, 2002). Wetlands were digitized from rectified 1926 aerials and classified according to the FLUCCS classification system. Wetland coverage for the 1999 data set was extracted from FLUCCS 1999 land use coverage provided by the SWFWMD, and topology for both the 1926 and 1999 wetland and surface waters were created. Statistical and spatial analysis was then performed on the vector feature class layers to determine net wetland loss and gain, by watershed, within the sub-basin study area. Results indicate that substantial and statistically significant net losses in areal extent occurred between the 1926 and 1999 study time frames in most sub-basins for freshwater forested, freshwater herbaceous, saltwater herbaceous, non-vegetated wetlands and in total wetland areal extent. Both open water and upland exhibited statistically significant net increases in areal extent over the same time period. Losses are directly attributable to human-activity such as excavation, ditching, draining, and filling.

Coral reefs are threatened in Florida and worldwide. Successful resource management requires rapid identification of anthropogenic sources of stress before they affect the reef community. I tested a multi-scale approach for assessing reef condition at seven reefs within the Florida Keys National Marine Sanctuary and Biscayne National Park between 2001 and 2003. I examined multiple environmental parameters to identify potential sources of stress. I utilized the Atlantic and Gulf Rapid Reef Assessment Biotic Reef Index to assess benthic community structure and an indicator species of Foraminifera (Amphistegina gibbosa) to determine if environmental conditions were suitable for calcareous organisms that host algal endosymbionts. Small tissue samples were extracted from colonies of Montastraea annularis species complex to assay a suite of cellular biomarkers to elucidate possible mechanisms of the coral stress response. I monitored regeneration rates of the resultant lesions to determine if the coral colonies were capable of recovering from damage. Multivariate data analyses indicated that corals at all study sites were experiencing stress with different degrees of response and decline. On reefs with coarse grain sediments that are adjacent to an intact mangrove shoreline, the Cellular Diagnostic System indicated that corals were responding to a xenobiotic stress but appeared to be compensating as evidenced by consistently high lesion regeneration rates, a high percentage of healed lesions, low coral mortality and high abundances of A. gibbosa. On reefs with silt-sized sediments adjacent to developed coastlines, corals also were responding to xenobiotic stresses, but were negatively affected as evidenced by low regeneration rates, a low percentage of healed lesions, high coral mortality, and low abundances of A. gibbosa. Corals at an 18 m offshore site exhibited abnormally low biomarker levels and some died during the study, indicating that sampled colonies were incapable of upregulating necessary protective proteins. Further research will be required to determine stressor sources. This study demonstrates that a multiple-indicator approach, spanning scales from cellular to community, can provide marine resource managers with data linking decline of coral populations to specific environmental conditions and events, thereby providing potential for early detection of stressors allowing for preventive management.
