A Comparative Approach To Understanding Sea Turtle Hatchling Metabolism During Emergence, Erin Cherish Redfearn Jan 2000

A Comparative Approach To Understanding Sea Turtle Hatchling Metabolism During Emergence, Erin Cherish Redfearn

Electronic Theses and Dissertations 2000 - 2009

Sea turtle nests were compared to determine the effects of nest depth on hatchling anaerobic metabolism in Juno Beach, Florida, USA. In situ nests of 3 species (Caretta caretta, Chelonia mydas and Dermochelys coriacea) were compared. Relocated loggerhead nests were studied under an experimental regime. Nest temperatures and oxygen concentrations were monitored. On the night of first emergence, blood samples were taken from hatchlings resting at the nest chamber bottom and sand surface, and digging to the sand surface. Samples were analyzed for lactate concentrations. Blood lactate levels were high in hatchlings actively digging and low for those resting. Lactate …

Calcium Requirement And Growth In The Hatchling Loggerhead Sea Turtle (Caretta Caretta L.), Jeanne Louise Alexander Jan 2000

Calcium Requirement And Growth In The Hatchling Loggerhead Sea Turtle (Caretta Caretta L.), Jeanne Louise Alexander

Electronic Theses and Dissertations 2000 - 2009

The calcium requirement in captive-raised hatchling loggerhead sea turtles (Caretta caretta) was investigated. Comparisons were made among turtles on 6 experimental diets and between captive and wild turtles. Diets consisted of trout chow diets containing 1%, 2%, 3%, or 4% calcium and 1.65% phosphorous, AquaMax 500RTM (2% Ca), and shrimp. Feeding trials lasted 28 days and changes in body size and bone density were measured. The calcium and phosphorous content of foods eaten by post-hatchlings in the sargassum were compared with captive diets. Results showed that shrimp was high in protein and low in calcium, with nearly twice as much …

Children's Cognitive Representations Of Parent-Child Interaction As Determinants Of Victimization And Aggression In The Peer Group, Jennifer Lynn Yunger Jan 2000

Children's Cognitive Representations Of Parent-Child Interaction As Determinants Of Victimization And Aggression In The Peer Group, Jennifer Lynn Yunger

Electronic Theses and Dissertations 2000 - 2009

Victimized children display debilitating thoughts, feelings and behaviors that may originate in family interactions and generalize to the peer group, causing children to be victimized by aggressive peers. This study tested the hypothesis that children's mental representations of their family experiences cause them to have reactions during peer interactions that lead to their victimization by peers. It was suggested that a perception of the self as helpless and a perception of the parent as controlling or threatening causes children to exhibit debilitated behavior among peers that contributes to their victimization. Also, certain perceptions of self and parent may contribute to …

Design Of 10-Transistor Low-Power Full Adders, Hung Tien Bui Jan 2000

Design Of 10-Transistor Low-Power Full Adders, Hung Tien Bui

Electronic Theses and Dissertations 2000 - 2009

We propose two approaches to design 1-bit full adders which can yield good performance at low power consumption. In the first approach, we design XOR/XNOR gates using a minimal number of CMOS transistors. Comparing with 10 different XOR/XNOR gates reported in literature, the new XOR/XNOR gates consume less power. The gates consisting of the smallest number of transistors are combined to create 1-bit full adders. The process is systematic and yields a total of 42 10-transistor full adders, 41 of which are new. Simulation results show that most of the new adders perform better than a previously existing 10-transistor adder …

Design Of A Frequency Shift Keying Array Receiver For The Acoustic Modem, Cecile. Boubli Jan 2000

Design Of A Frequency Shift Keying Array Receiver For The Acoustic Modem, Cecile. Boubli

Electronic Theses and Dissertations 2000 - 2009

Currently, our acoustic modems are used to communicate underwater to Autonomous Underwater Vehicles AUVs. These modems have only one sensor and can transmit at low data rates (from 200 to 1200 bits per second) using Frequency Shift Keying (FSK) modulation. A two-dimensional array receiver (MillsCross) has been developed to receive underwater signals with more reliability, at a higher data rate (about 30,000 bits per second). This array has been designed to operate with Phase Shift Keying modulated signals. The purpose of this thesis is to design and implement a signal processing software to demodulate and decode FSK signals acquired by …

Design Of An Ankle Implant Using Design For Assembly (Dfa) Principles, Ha Van Vo Jan 2000

Design Of An Ankle Implant Using Design For Assembly (Dfa) Principles, Ha Van Vo

Electronic Theses and Dissertations 2000 - 2009

Current ankle implant designs have shown significant improvements in last ten years. However, failure rates are still high and about 30% of patients ended up with fusion joint or lower leg amputation after ten years of first operations because of long term associated pain. A new ankle joint implant presenting in this study (Vo-ankle implant) was designed to base on the Design for Assembly (DFA) principles to optimize the device biomechanically. It overcomes most of problems shown in current ankle implants. The new ankle implant has four major advantages over the current models. First, the new ankle constructed to distribute …

Does Residential Landscape Type Affect Nitrogen Runoff And Leaching?, John Erickson Erickson Jan 2000

Does Residential Landscape Type Affect Nitrogen Runoff And Leaching?, John Erickson Erickson

Electronic Theses and Dissertations 2000 - 2009

Intensely maintained turfgrass landscapes have some potential for loss of fertilizer nitrogen (N) in both runoff and leaching. Lower maintenance vegetation used in mixed-species landscapes may reduce N leaching and runoff, which is important for reducing environmental pollution of surface and ground waters. However, few studies have examined this paradigm. Therefore, we constructed a field-scale facility to compare fertilizer N runoff and leaching between St. Augustinegrass (Stenotaphrum secundatum (Walt.) Kuntze cv. 'Floratam') and a mixed-species landscape designed by the Florida Yards and Neighborhoods (FYN) program. A blended granular fertilizer was applied at a rate of 300 and 150 kg N …

Dynamics Of Human Sensorimotor Coordination: From Behavior To Brain Activity, Yanqing Chen Jan 2000

Dynamics Of Human Sensorimotor Coordination: From Behavior To Brain Activity, Yanqing Chen

Electronic Theses and Dissertations 2000 - 2009

The dynamics of human sensorimotor coordination are studied at behavioral and neural levels through temporal synchronization and syncopation tasks. In experiment 1, subjects synchronized their finger movements (in-phase) with a metronome at 2.0Hz and 1.25Hz for 1200 cycles. Fluctuations of timing errors were analyzed through correlation, power spectrum analyses and Maximum Likelihood Estimation (MLE). Results indicated that the synchronization error time series was characterized by a 1/falpha type of long memory process with alpha = 0.5. Previous timing models based upon motor program or simple "central clock" ideas were reviewed to show that they could not explain such long range …

The Conundrum Of Executive Compensation, Mark J. Loewenstein Jan 2000

The Conundrum Of Executive Compensation, Mark J. Loewenstein

Publications

Much of the scholarship on executive compensation that appears in law reviews assumes that large U.S. corporations overpay their chief executive officers ("CEOs"). This assumption is understandable, as many of these compensation packages are indeed stunning. The question of whether CEOs are overpaid, however, is complicated. Some scholars in other disciplines, principally in economics and management science, have studied the issue but, as this Article demonstrates, this literature does not confirm the assumption. Indeed, some studies suggest that CEO pay is competitive. Moreover, efforts to reduce the level of executive compensation may have the unintended consequence of achieving the opposite …

Host Selection, Chemical Detection, And Protection Of The Symbiotic Pinnotherid Crabs Dissodactylus Crinitichelis And Clypeasterophilus Rugatus Associated With Echinoderms, Misty N. Reeves Jan 2000

Host Selection, Chemical Detection, And Protection Of The Symbiotic Pinnotherid Crabs Dissodactylus Crinitichelis And Clypeasterophilus Rugatus Associated With Echinoderms, Misty N. Reeves

Electronic Theses and Dissertations 2000 - 2009

Host selection by Dissodactylus crinitichelis and Clypeasterophilus rugatus for different echinoderms was investigated. Initial preference (within 24 h of collection) and preference after "conditioning" with an alternate host were compared. D. crinitichelis initially preferred its field host, the sand dollar Encope michelini, but after conditioning switched its host preference to a non-field host, the sea biscuit Clypeaster rosaceus. This switch in host preference after conditioning occurred despite consumption of numerous crabs (86 out of 167) by C. rosaceus. Clypeasterophilus rugatus initially preferred its field host, the sea biscuit Clypeaster rosaceus, but showed little change in host preference after conditioning. These …

Hydrodynamics And Control Of An Autonomous Underwater Vehicle Equipped With A Vectored Thruster, Page Yann Georges Le Jan 2000

Hydrodynamics And Control Of An Autonomous Underwater Vehicle Equipped With A Vectored Thruster, Page Yann Georges Le

Electronic Theses and Dissertations 2000 - 2009

In this study, a laminar flow hull shape is implemented on an Autonomous Underwater Vehicle (AUV), with boundary layer suction at the aft end of the hull to prevent separation. The hull shape has the largest diameter of the vehicle near the aft end of the hull resulting in an accelerating flow over the majority of the hull's surface. The problem of axially symmetrical flow around the AUV is solved using a potential flow analysis. A finite difference algorithm evaluates the stream function, leading to the computation of fluid velocity and pressure fields. The boundary layer characteristics are analyzed to …

New Woman Before She Was New: Olive Schreiner's "The Story Of An African Farm" And Fanny Fern's "Ruth Hall", Dana Jo Richardson Jan 2000

New Woman Before She Was New: Olive Schreiner's "The Story Of An African Farm" And Fanny Fern's "Ruth Hall", Dana Jo Richardson

Electronic Theses and Dissertations 2000 - 2009

Despite the designation of Olive Schreiner's Lyndall in The Story of an African Farm as the first "New Woman" in literature, the nineteenth-century New Woman, with her high ideals and belief in an androgynous compromise of sex roles, is exemplified by Fanny Fern's heroine Ruth in the novel Ruth Hall. While Lyndall speaks of social injustice done to women, the limitations of her provincial setting preclude her protests from achieving the level of social activism; however, Ruth's protests, in the form of newspaper articles, do reach the level of social activism. Schreiner's androgynous ideal becomes lost in a role reversal …

Preliminary Investigation Of Ceramic Styles And Chronology At The Rio Chico Site (Omjplp170), Manabi, Ecuador, Monica. Oyola-Coeur

Electronic Theses and Dissertations 2000 - 2009

This thesis studies a ceramic assemblage recently excavated at Rio Chico (OMJPLP170), a coastal multi-component site situated in Southern Manabi, Ecuador. Stratigraphic excavations provided the data for analysis, which primarily consisted of utilitarian wares that were examined within the archaeological context. Ceramic utilitarian wares were used to reconstruct the cultural sequence at Rio Chico, dating from the Early Formative Period Valdivia Phase to the Integration Period Manteno Phase, and to assess the use of space throughout the occupation. Additionally, ceramic vessel reconstruction provided insights about the types of activities and behavioral patterns of the prehispanic inhabitants of Rio Chico in …

Representacion De La Aniquilacion De La Creatividad Artistica Femenina En Obras Seleccionadas De Elena Poniatowska, Ana Adriazola-Rodriguez Jan 2000

Representacion De La Aniquilacion De La Creatividad Artistica Femenina En Obras Seleccionadas De Elena Poniatowska, Ana Adriazola-Rodriguez

Electronic Theses and Dissertations 2000 - 2009

The annihilation of women's artistic creativity in selected works by the Mexican writer Elena Poniatowska is a result of societal conditioning. Two short stories from Lilus Kikus and the short novel Querido Diego, te abraza Quiela portray the process of deterioration and demeaning obliteration of women's creative faculties, as they are conditioned to accept the conventional roles of wife and mother. Poniatowska's texts posit that, upon assuming these roles, the exercise of the creative artist's use of her imagination is postponed or detrimentally transformed forever. In the selected texts, women's artistic creativity is chronicled first at its best while the …

Rhetorical Analysis Of A Feminine Style And Feminist Research In Scholarly Communication Journals, Diane Theresa Bifano Jan 2000

Rhetorical Analysis Of A Feminine Style And Feminist Research In Scholarly Communication Journals, Diane Theresa Bifano

Electronic Theses and Dissertations 2000 - 2009

Nine journal articles were analyzed in order to understand gendered composition and what makes writing an article feminine and what makes it masculine. The journals reviewed were Communication Monographs, Communication Theory, Critical Studies in Mass Communication, Human Communication Research, Quarterly Journal of Speech, and Women Studies in Communication. Categories were compiled to include the characteristics of a feminine style in feminist research, and a masculine style in traditional research. This analysis takes a rhetorical approach in order to address a more gender diverse perspective in research. As a result of many published articles reflecting a theme of a "dominant masculinist …

Role Of Professional Judgment In The Application Of United States Accounting Standards: An Experimental Study Of The Effect Of Professional Judgment On Financial Reporting Decisions Of Accountants, Randall Wesley Rentfro Jan 2000

Role Of Professional Judgment In The Application Of United States Accounting Standards: An Experimental Study Of The Effect Of Professional Judgment On Financial Reporting Decisions Of Accountants, Randall Wesley Rentfro

Electronic Theses and Dissertations 2000 - 2009

This study examines two questions: (1) whether the level professional judgment required in the application of accounting standards affects the comparability of financial reporting; (2) whether financial statement preparers exploit the professional judgment in accounting standards in order to engage in earnings management. The study is motivated by former FASB Chair Dennis Beresford's call for simple accounting standards which rely heavily on the exercise of professional judgment and by SEC Chair Arthur Levitt's concerns that managers exploit the flexibility in accounting standards to engage in earnings management. Agency theory is used to develop two hypotheses which predict the conditions under …

Source Of Null Phonemic Masking Effects With Homophones: The Role Of Phonological Competition And List Structure, Patricia Lee Jarman Jan 2000

Source Of Null Phonemic Masking Effects With Homophones: The Role Of Phonological Competition And List Structure, Patricia Lee Jarman

Electronic Theses and Dissertations 2000 - 2009

Three experiments investigated the source of null phonemic masking effects with homophones under phonology discouraging conditions. Particularly, we examined whether the phonemic masking effect depends on the dominance of the homophones and list structure. For this end, we compared the phonemic masking effect for subordinate and dominant homophones presented in either a blocked or mixed condition. Our findings indicated that neither of these two factors systematically modulated the phonemic masking effect. However, there was some evidence for reliance on phonology in each of the conditions.

The Effect Of Filtered Roadway Lighting On Nesting By Loggerhead Sea Turtles (Caretta Caretta L.), Jeffrey P. Pennell Jan 2000

The Effect Of Filtered Roadway Lighting On Nesting By Loggerhead Sea Turtles (Caretta Caretta L.), Jeffrey P. Pennell

Electronic Theses and Dissertations 2000 - 2009

The purpose of this study was to determine if filtered street lighting affected the nesting behavior of loggerhead sea turtles ( Caretta caretta L.). My study site was a nesting beach at Carlin Park, Jupiter, Florida. During the 1999 nesting season, portions of the beach were either kept dark or were illuminated by four 70 W high-pressure sodium (HPS) streetlights, each housed in a cut-off fixture covered by an acrylic (model #2422) filter. These filters excluded all light wavelengths below 540 nm. The excluded wavelengths repel nesting females. Daily counts of nesting and non-nesting crawls were made. Data from the …

Test Of Bem's Model Of The Development Of Sexual Orientation, Priscilla Ann Rouse Jan 2000

Test Of Bem's Model Of The Development Of Sexual Orientation, Priscilla Ann Rouse

Electronic Theses and Dissertations 2000 - 2009

This study tested Bem's (1996) "Exotic Becomes Erotic" theory of sexual orientation. Participants were 182 4th- through 8 th-graders. In accord with Bem's theory, sex-typing (i.e., sex-typed traits, interests, and playmate preferences) and goodness-of-fit with one's gender predicted heterosexual identity. However, goodness-of-fit did not mediate relations of sex-typing to heterosexual identity; instead, sex-typing mediated the relation of felt similarity to heterosexual identity. Implications for alternative models are discussed.

Teacher Attitudes Toward Supervision And Evaluation In The Developmental Research Schools Of The State Of Florida, Donna Londeree Mccaffrey Jan 2000

Teacher Attitudes Toward Supervision And Evaluation In The Developmental Research Schools Of The State Of Florida, Donna Londeree Mccaffrey

Electronic Theses and Dissertations 2000 - 2009

The developmental research schools, or laboratory schools, of the state of Florida became single-school public school districts in 1991. This allowed the four Florida laboratory schools to receive full-time equivalency funding from the state, but also required the schools to have state-mandated programs in place. Laboratory school teachers have varying roles that include teacher, researcher, writer, and presenter. These roles have caused discussion about appropriate performance appraisal methods for laboratory school teachers. In Florida, public school districts must have a human resources and management development plan that addresses evaluation and supervision of teaching personnel. With the passage of the Florida …

Variability In Winter Mass Balance Of Northern Hemisphere Glaciers And Relations With Atmospheric Circulation, Gregory J. Mccabe, Andrew G. Fountain, Mark Dyurgerov Jan 2000

Variability In Winter Mass Balance Of Northern Hemisphere Glaciers And Relations With Atmospheric Circulation, Gregory J. Mccabe, Andrew G. Fountain, Mark Dyurgerov

Geography Faculty Publications and Presentations

An analysis of variability in the winter mass balance (WMB) of 22 glaciers in the Northern Hemisphere indicates two primary modes of variability that explain 46% of the variability among all glaciers. The first mode of variability characterizes WMB variability in Northern and Central Europe and the second mode primarily represents WMB variability in northwestern North America, but also is related to variability in WMB of one glacier in Europe and one in Central Asia. These two modes of WMB variability are explained by variations in mesoscale atmospheric circulation which are driving forces of variations in surface temperature and precipitation. …

Entrainment Of Larval Release In An Intertidal Crab ( Uca Thayeri) After Exposure To A Different Tidal Regime: Testing The "Plasticity" Hypothesis, Ann Weaver Jan 2000

Entrainment Of Larval Release In An Intertidal Crab ( Uca Thayeri) After Exposure To A Different Tidal Regime: Testing The "Plasticity" Hypothesis, Ann Weaver

Electronic Theses and Dissertations 2000 - 2009

Endogenous rhythms allow most organisms to synchronize their behavior and physiology with physical cycles that vary on a daily, lunar or annual cycle. Populations within species often show variation in the timing of functionally identical rhythms. This variation occurs because physical cycles may differ with geography. The purpose of this study was to determine whether hatching rhythms shown by fiddler crabs (Genus Uca) on one coastline could be entrained by the different tide patterns present at another coastline. To test this I transferred breeding females (Uca thayeri) from mangroves on the west coast of Florida to mangroves on the east …

Examples Of Deterministic And Monte Carlo Algorithms For Cryptographic Applications, Joe Cullen Mcpherson Jan 2000

Examples Of Deterministic And Monte Carlo Algorithms For Cryptographic Applications, Joe Cullen Mcpherson

Electronic Theses and Dissertations 2000 - 2009

In this thesis two different types of computer algorithms, Deterministic and Monte Carlo, are illustrated. Implementations of the Berlekamp-Massey algorithm and the Parallelized Pollard Rho Search are described here. The questions of what these two algorithms provide to the field of cryptography and why they have proven themselves important to cryptography are briefly discussed. It is also shown that with a little extra knowledge, the Parallelized Pollard Rho Search may be easily modified to improve its performance.
