Does Perceived Parenting Affect Children's Attachment Style In Middle Childhood?, Brooke C. Corby
Does Perceived Parenting Affect Children's Attachment Style In Middle Childhood?, Brooke C. Corby
Electronic Theses and Dissertations 2000 - 2009
This longitudinal study examined the likely direction of influence between perceived parenting and attachment style in middle childhood. In each of two successive years, measures of perceived parenting behaviors and of attachment style were administered to 164 children (mean age 10.2 in Year 1). Avoidant (but not preoccupied) attachment predicted change in perceived parenting over time, in that avoidant children perceived their mothers as increasingly overprotective, as less monitoring, as less affectionate, and as providing less reliable support over time. There was little evidence that perceived parenting led to change in attachment style over time, although low perceived maternal support …
Does Leadership Matter? The Effects Of Information Technology Expertise On The Market Value And Performance Of A Firm, Ashraf A. Khallaf
Does Leadership Matter? The Effects Of Information Technology Expertise On The Market Value And Performance Of A Firm, Ashraf A. Khallaf
Electronic Theses and Dissertations 2000 - 2009
This dissertation examines the stock market reaction to 474 announcements of hiring chief information officers (CIOs) in the 1987--2002 period, and firm performance for periods up to two years following the CIO appointment. The study reports that the announcements are associated with significantly positive abnormal returns (0.48 percent). The returns are more pronounced when the new CIO is hired from an IT leader firm (1.94 percent). Abnormal returns are significantly positive related with the CIO's level of education and high-technology firms, and negatively related with firm size. In addition, there is no significant difference in market reaction between the announcements …
Efficient Implementation Of Zero-Knowledge Based Identification Protocols, Michelle Elizabeth Barella
Efficient Implementation Of Zero-Knowledge Based Identification Protocols, Michelle Elizabeth Barella
Electronic Theses and Dissertations 2000 - 2009
A zero knowledge identification protocol is an interactive proof system that allows a person to prove that he knows a secret key associated with his identity without revealing the secret key. This type of protocol is the topic of a fairy tale, by Gustavus Simmons called the King's Dilemma, about a king and the problem he has with thieves impersonating his tax collectors. It describes a zero-knowledge identification protocol that will rid the king of his problem. I present this system, the motivation for this thesis, and the transformations from this protocol, that uses lead weights and containers, to protocols …
Dwellings And Beings, Spaces And Places: A Topoanalysis Of Vladimir Nabokov's "Lolita", Sally M. Badawi
Dwellings And Beings, Spaces And Places: A Topoanalysis Of Vladimir Nabokov's "Lolita", Sally M. Badawi
Electronic Theses and Dissertations 2000 - 2009
This thesis conducts a toponalysis of phenomenological notions of "Being" and "dwelling" in Vladimir Nabokov's Lolita and concludes that the existence of the characters rests in their relationships to dwelling and the ramifications of their separation from home. As Humbert and Lolita experience alienation and uprooted-ness, they embark upon a two-year journey which orbits around reality, as their travels follow what David Seamon calls, Journey-Dwelling Spiral, however, without ever attaining a state of dwelling. As they attempt to overcome their disorientation, Lolita distances herself from Humbert, and Humbert projects his nympholepsy onto another, Quilty. Because Lolita succeeds in her goal, …
Effects Of Cement Alkalinity, Exposure Conditions And Steel-Concrete Interface On The Time-To-Corrosion And Chloride Threshold For Reinforcing Steel In Concrete, Jingak. Nam
Electronic Theses and Dissertations 2000 - 2009
Effects of (1) cement alkalinity (low, normal and high), (2) exposure conditions (RH and temperature), (3) rebar surface condition (as-received versus cleaned) and (4) density and distribution of air voids at the steel-concrete interface on the chloride threshold and time-to-corrosion for reinforcing steel in concrete have been studied. Also, experiments were performed to evaluate effects of RH and temperature on the diffusion of chloride in concrete and develop a method for ex-situ pH measurement of concrete pore water. Once specimens were fabricated and exposed to a corrosive chloride solution, various experimental techniques were employed to determine time-to-corrosion, chloride threshold, diffusion …
Dynamic Stability Of Fluid-Conveying Pipes On Uniform Or Non-Uniform Elastic Foundations, Pablo J. Vittori
Dynamic Stability Of Fluid-Conveying Pipes On Uniform Or Non-Uniform Elastic Foundations, Pablo J. Vittori
Electronic Theses and Dissertations 2000 - 2009
The dynamic behavior of straight cantilever pipes conveying fluid is studied, establishing the conditions of stability for systems, which are only limited to move in a 2D-plane. Internal friction of pipe and the effect of the surrounding fluid are neglected. A universal stability curve showing boundary between the stable and unstable behaviors is constructed by finding solution to equation of motion by exact and high-dimensional approximate methods. Based on the Boobnov-Galerkin method, the critical velocities for the fluid are obtained by using both the eigenfunctions of a cantilever beam (beam functions), as well as the utilization of Duncan's functions. Stability …
Emotion, Language, And Heroism In C. S. Lewis's Space Trilogy, Heather Marie Leger
Emotion, Language, And Heroism In C. S. Lewis's Space Trilogy, Heather Marie Leger
Electronic Theses and Dissertations 2000 - 2009
C. S. Lewis's Space Trilogy presents a hero in the person of philologist Dr. Elwin Ransom. Lewis's presentation exhibits a purposeful and precise use of language that describes experience and characterizes emotional authenticity. This use of language becomes particularly interesting when examined in light of the theories of Owen Barfield, who along with Lewis recognizes that myth is significant as an expression of language and its relation to the human condition, and Joseph Campbell, who discusses the journey of the hero. In his own writings Lewis contends that there has been a process of working against the "mythical imagination," moving …
Efficient Localized Broadcast Algorithms In Mobile Ad Hoc Networks, Wei. Lou
Efficient Localized Broadcast Algorithms In Mobile Ad Hoc Networks, Wei. Lou
Electronic Theses and Dissertations 2000 - 2009
The broadcast operation has a most fundamental role in mobile ad hoc networks because of the broadcasting nature of radio transmission, i.e., when a sender transmits a packet, all nodes within the sender's transmission range will be affected by this transmission. The benefit of this property is that one packet can be received by all neighbors while the negative effect is that it interferes with other transmissions. Flooding ensures that the entire network receives the packet but generates many redundant transmissions which may trigger a serious broadcast storm problem that may collapse the entire network. The broadcast storm problem can …
Effects Of Joint Book Reading Emphasizing Print Focus On Print Awareness In Preschool Children With Down Syndrome: A Preliminary Investigation, Barbara J. Fries
Effects Of Joint Book Reading Emphasizing Print Focus On Print Awareness In Preschool Children With Down Syndrome: A Preliminary Investigation, Barbara J. Fries
Electronic Theses and Dissertations 2000 - 2009
Most typically developing children experience a wide variety of literary experiences before they ever learn to read. Young children with intellectual impairments may not be as fortunate due to multiple developmental delays and therapeutic needs. Research has supported joint book reading as an effective intervention technique for children with language impairments and other risks for developmental delays. Two research questions were explored in this preliminary investigation. First, to what extent does a specific joint book reading training program, emphasizing a print focus, increase verbal and nonverbal print referencing behaviors in parents during joint book reading? Secondly, to what extent does …
Effect Of The Neurological Impress Method On Oral Reading Skills In An At-Home Program, Colleen Borden
Effect Of The Neurological Impress Method On Oral Reading Skills In An At-Home Program, Colleen Borden
Electronic Theses and Dissertations 2000 - 2009
Struggling readers need guided and motivating instruction on a daily basis in order to improve their literacy skills in a significant way. One approach for providing this type of instruction is through the use of an at-home literacy program. In this study, parents were given training and feedback in the use of simple, inexpensive, yet motivating reading techniques which they used at home with their children. A comprehensive literature review on the Neurological Impress Method (NIM), oral reading fluency, and the connection between parent involvement and student achievement and/or literacy development was conducted. Based on information obtained from the literature …
Environment's Influence On The Protagonists In Richard Wright's Fiction, Erin. Riley
Environment's Influence On The Protagonists In Richard Wright's Fiction, Erin. Riley
Electronic Theses and Dissertations 2000 - 2009
The protagonists in Richard Wright's fiction often face insurmountable obstacles. The environment plays an important role in the actions of the protagonist. Although Wright's fictional settings were often centered in the United States, the specific U.S. location was often integral to the resolution of the story. The protagonists are exposed to similar situations, but depending upon the northern American or southern American environments, they may encounter vastly different outcomes. Neither environment proves itself to be beneficial to Wright's protagonists. The racism in both northern and southern environments is the defining factor in the development of the protagonists. There are differences …
Evaluation Of The Microbiological Quality Of Sandy Beaches: A Novel Approach, Renuka Lisa Mohammed
Evaluation Of The Microbiological Quality Of Sandy Beaches: A Novel Approach, Renuka Lisa Mohammed
Electronic Theses and Dissertations 2000 - 2009
A novel, 'near-real' time technique; peptide nucleic acid chemilumiscent in situ hybridization (PNA CISH), was developed and validated for detecting, enumerating and identifying potential indicators (Staphyloccus aureus and Pseudomonas aeruginosa) of beach quality. To understand the dynamics of bacterial indicators a plethora of physical, chemical and biological parameters were tested under field and lab conditions. Escherichia coli tagged with green fluorescence protein (GFP) was used to assess the impact of wave energy and rainfall on seawater counts. PNA CISH and plate counts correlated strongly (r = 0.94 to r = 0.86). Temperature, salinity, nutrient availability and predation significantly influenced the …
Essays On High-Tech Acquisitions And Divestitures, Georgia. Benou
Essays On High-Tech Acquisitions And Divestitures, Georgia. Benou
Electronic Theses and Dissertations 2000 - 2009
Since the early 1990s there has been a substantial increase both in mergers and acquisitions (M&A) as well as in divestitures of high-tech companies. This dissertation examines the takeover and divestiture activity in high-tech markets in an effort to extend our current knowledge regarding high-tech companies. In that context, various firm characteristics and their relation to firm performance are investigated. Furthermore, an attempt is made to examine the role of investment banks and their impact---if any---on shareholder wealth. This study finds that for domestic high-tech acquisitions, the higher the level of the target's R&D expenditures, the lower the bidder's announcement …

This research compared the effectiveness of efforts by the Palm Beach County School District and the Miami-Dade County School District to raise academic achievement at 39 comparable low-performing schools in their districts. Palm Beach County School District mandated a highly prescriptive plan that involved intense district staff involvement during the 2003--2004 school year. Miami-Dade County School District utilized a highly descriptive plan that entailed only mild to moderate involvement from district staff. A matched-pair research design was used to examine what differences, if any, existed between the learning gains of comparable schools in Palm Beach County and Miami-Dade County as …
Finite Element Modeling For Dislocation Generation In Semiconductor Crystals Grown From The Melt, Xinai. Zhu
Finite Element Modeling For Dislocation Generation In Semiconductor Crystals Grown From The Melt, Xinai. Zhu
Electronic Theses and Dissertations 2000 - 2009
Dislocations in Gallium Arsenide (GaAs) and Indium Phosphide (InP) single crystals are generated by excessive stresses that are induced during the crystal growth process, and the fabrication and packaging of microelectronic devices/circuits. The presence of dislocations has adverse effects on the performance, lifetime and reliability of the GaAs and InP-based devices/circuits. It is well known that dislocation density can be significantly reduced by doping impurity atoms into the GaAs and InP crystal and/or decreasing the thermal stresses in these crystals during their growth process. In order to reduce the dislocation density generated in the GaAs and InP crystals, the influence …
Flesh Impressions: Television Texts Of Cosmetic Surgery And Audience Negotiation, Heather O'Neil Hutton
Flesh Impressions: Television Texts Of Cosmetic Surgery And Audience Negotiation, Heather O'Neil Hutton
Electronic Theses and Dissertations 2000 - 2009
Both incredibly personal and inherently social, cosmetic surgery procedures intended to reconfigure the body toward a more culturally acceptable physicality and the increase in television representations of the phenomenon provoke a complex debate regarding the social, psychological, medical and ethical implications of such practices. This thesis raises the question: Do television texts of cosmetic surgery and their potential consumers reproduce or challenge the hegemony of cosmetic surgery as a cultural practice? Using qualitative, social scientific methodology to analyze current examples of such television texts and study viewer negotiation of these texts, the study concludes that television texts are most likely …
Experience Of Being A Leader During A Ropes Course Program And At Work: A Heuristic Inquiry, Malika Starr
Experience Of Being A Leader During A Ropes Course Program And At Work: A Heuristic Inquiry, Malika Starr
Electronic Theses and Dissertations 2000 - 2009
This study explored the question, "What is the experience of being a leader during participation in a ropes course program and at work?" The ropes course as a training medium provides opportunities for people to engage in challenging activities to improve interpersonal skills. From ten ropes course programs and 130 participants, the researcher purposefully selected thirteen co-researchers who exhibited pre-determined leadership behaviors. Dialogue with each co-researcher provided rich descriptions and metaphors about the experience of being a leader. Using heuristic research methods, the researcher analyzed the data and uncovered redundant themes to better understand the phenomenon of being a leader. …
Father, The Son And The Sense Of Humor: The Novels Of John Fante, Emanuele. Pettener
Father, The Son And The Sense Of Humor: The Novels Of John Fante, Emanuele. Pettener
Electronic Theses and Dissertations 2000 - 2009
John Fante is a well-known novelist in Italy and Europe, but still very much unknown and unrecognized in the United States. Yet, John Fante is an American writer and, though his father came from Torricella Peligna---a small town in the middle of Italy---Fante did not speak Italian; he felt American and, most of all, he wanted to be considered an American writer. His novels are imbued with both "Italian Americanicity" as well as "Americanicity". In fact, throughout his eight novels, one of the main topics is the American motif par excellence, the American Dream. What are the reasons for such …
Idee De L'Amour Dans Le Couple Chez Beauvoir, Marie-Pierre. Grosjean
Idee De L'Amour Dans Le Couple Chez Beauvoir, Marie-Pierre. Grosjean
Electronic Theses and Dissertations 2000 - 2009
One of the constants in Beauvoir's work is her lifelong attention to the phenomenon of love and the idea of the couple. In her philosophy as well as in her fiction, she develops a binary concept of love. On the one hand is "authentic love," connoting respect and reciprocity; on the other is "inauthentic love," a function of conquest and annexation. Because of her adherence to the tenets of Existentialism, Beauvoir, the feminist, skillfully negotiates between the notions of love and freedom.
Great Mind Is Androgynous: A Look At The Late Poetry Of Sylvia Plath Through Virginia Woolf's Theory Of The Androgynous Consciousness, Shilo R. Blackburn
Great Mind Is Androgynous: A Look At The Late Poetry Of Sylvia Plath Through Virginia Woolf's Theory Of The Androgynous Consciousness, Shilo R. Blackburn
Electronic Theses and Dissertations 2000 - 2009
The female subject in the late poetry of Sylvia Plath experiences a physical and intellectual transformation, as Plath attempts to challenge and redefine the social construction of woman through Virginia Woolf's influence. Plath aspires to achieve a poetic voice that embodies characteristics of both genders simultaneously, an androgynous consciousness by Woolf's account, and one that can speak despite Western culture's imposed inferiority of women writers. Since traditionally masculine language has defined women's social roles through their physical bodies, Plath's aim is to immerse her female subject in the experiences of her corporeal body as a means to transcend her physical …
Home Range And Movements Of Juvenile Atlantic Green Turtles (Chelonia Mydas L.) On Shallow Reef Habitats In Palm Beach, Florida, United States Of America, Christopher Makowski
Home Range And Movements Of Juvenile Atlantic Green Turtles (Chelonia Mydas L.) On Shallow Reef Habitats In Palm Beach, Florida, United States Of America, Christopher Makowski
Electronic Theses and Dissertations 2000 - 2009
This study's objectives were to determine if coastal (shallow-water, oceanic reef) aggregations of juvenile green turtles (Chelonia mydas L.) in Palm Beach, Florida occupied distinct home ranges and how these home ranges compared in size and resource availability with those studied elsewhere. Six immature green turtles were captured, measured, and subjected to esophageal lavage to determine diet. Each turtle was returned to its initial capture site within 24 h with an ultrasonic transmitter used to track movements. All turtles were <65 cm SCL, had ingested similar macroalgae, and occupied markedly small home ranges (mean = 2.38 +/- 1.78 km 2), largely restricted to the reef itself. Diving and feeding activity peaked during the day; at night, activity was minimal. The food and sleeping site resource distribution at this specific location coincides with the turtles' home range size and shape, with considerable overlap of core areas.
Ideological Complexity Of Kipling, Jonathan D. Noble
Ideological Complexity Of Kipling, Jonathan D. Noble
Electronic Theses and Dissertations 2000 - 2009
The works of Kipling are generally read under the discursive ideology of Orientalism. According to Edward Said, Orientalism is an institution for dominating the Orient with Foucauldian power/knowledge. While much of Kipling's work falls easily within the lines of Orientalism, important exceptions disrupt this singular reading. The hybrid character Kim, for example, demonstrates an uncertainty concerning the identity of the Anglo-Indian as colonizer constructed along racial lines, where white Anglo-Indian represents colonizer and brown Indian represents colonized. This simplified racial division is further problematized by Kipling's attention to social class in other works of prose and verse, which place the …
Exploration Of The Effectiveness Of A Phase Approach To Nutrition Counseling Using The Transtheoretical And Brief Intervention Models, Kaye-Ann. Grant
Exploration Of The Effectiveness Of A Phase Approach To Nutrition Counseling Using The Transtheoretical And Brief Intervention Models, Kaye-Ann. Grant
Electronic Theses and Dissertations 2000 - 2009
Registered dietitians, while knowledgeable in food and nutrition, are also intrinsically educators, a role that is now receiving in-depth exploration. As nutrition educators or counselors, dietitians have been stereotyped as food cops (Licavoli, 1995, p. 751); that is, individuals who provide the dos and don'ts list. Research in the area of nutrition education may foster movement away from this stereotype. The purpose of this study was to compare the effectiveness of traditional nutrition counseling with stage-matched nutrition counseling by registered dietitians using clients in acute care settings while measuring behavioral and cognitive change outcomes. An experimental design using randomly assigned …
Influence Of Chlorides And Surface Condition On Pitting Potential Of High Performance Reinforcing Steel, Virginie Edwige Leroux
Influence Of Chlorides And Surface Condition On Pitting Potential Of High Performance Reinforcing Steel, Virginie Edwige Leroux
Electronic Theses and Dissertations 2000 - 2009
In order to identify the influence of chlorides and surface finish on pitting potential of high performance reinforcing steel, cyclic polarization scans were performed on types 304, 2201 and 3Cr12 stainless steels and MMFX-II in simulated pore solution to which chloride was incrementally added. Furthermore, the surface condition was investigated with regard to the pitting potential. Pitting potential distributions versus the chloride content and surface finish were obtained. Pitting resistance was lowered as chloride was added and as the surface became rougher. Furthermore, a critical chloride to hydroxide ratio as a function of potential was determined for each material. Finally, …

Impact Of Block Scheduling On Academic Achievement And The Perceptions Of Teachers And Administrators In Selected South Florida High Schools, Michael Cosimano
Electronic Theses and Dissertations 2000 - 2009
The purpose of this study was to determine the impact of scheduling alternatives on (a) student achievement, student behavior, and attendance rates and (b) teacher and administrator perceptions. Archival data for student achievement, behavior, and attendance were obtained from the Palm Beach County School District. Perceptions of teachers and administrators were obtained through data collected from questionnaires administered through participating schools in this study. The research took place at three high schools using either 4 x 4, A/B, or modified block schedules and two high schools using traditional schedules. The block-scheduled schools were used in a similar study in 1996 …
Influence Of Depth-Dependent Sediment Properties On The Pressure Reflection Coefficient At Normal Incidence Using The Biot-Stoll Model, Marianne. Joussein
Influence Of Depth-Dependent Sediment Properties On The Pressure Reflection Coefficient At Normal Incidence Using The Biot-Stoll Model, Marianne. Joussein
Electronic Theses and Dissertations 2000 - 2009
The impact of depth-dependent geophysical parameters on the acoustic pressure reflection coefficient is studied at normal incidence using the Biot-Stoll theory in porous marine sediments. The seabed is modeled as a sediment layer with depth-dependent properties on top of a homogeneous half-space, as originally proposed by Stern. There is no discontinuity in sediment properties between the layer and the half-space. The reflection coefficient is determined by the evaluation of boundary conditions at the water-sediment layer interface and the sediment layer-half-space interface. Results are obtained for different types of sediment, from medium size sands to silty clay, and different porosity profiles …
Langston Hughes's Jesse B. Semple Commentaries: A Nietzschean Reading, Tina. Angelone
Langston Hughes's Jesse B. Semple Commentaries: A Nietzschean Reading, Tina. Angelone
Electronic Theses and Dissertations 2000 - 2009
Friedrich Nietzsche's notion of the Apollonian/Dionysian opposition found in The Birth of Tragedy provides a means to analyze Langston Hughes's Jesse B. Semple commentaries. The language and archetypal characters found in the Semple commentaries demonstrates the shifting balance between the struggles and the triumphs of some American Negroes. This shifting balance is represented by the Dionysian and Apollonian traits of Simple and the narrator, Boyd. By creating these characters, Hughes is able to display the importance of the low-down culture for some black artists. Through the intoxicated Dionysian insight of Semple and the Apollonian logos of the narrator, Hughes demonstrates …
Low Power And High Performance Centralized Full Adder, Sidharth. Srivastav
Low Power And High Performance Centralized Full Adder, Sidharth. Srivastav
Electronic Theses and Dissertations 2000 - 2009
In this thesis, we proposed a low power and high performance architecture for 1-bit full adder design. The proposed architecture was proven to offer a wide range of performance ability in terms of power consumption and speed. We implemented the architecture using a 2-input 2 multiplexers, an XOR and an XNOR gate. The proposed architecture and the Standard full adder were designed and simulated using Lasi, Winspice and Silos. Silos, a logic simulation environment was used in the design and verification of the proposed architecture and the standard full adder that were modeled with Verilog hardware description language. Lasi was …
"And Yet God Has Not Said A Word!": Robert Browning And The Romantic Killer In Literature, Erin. Burns-Davies
"And Yet God Has Not Said A Word!": Robert Browning And The Romantic Killer In Literature, Erin. Burns-Davies
Electronic Theses and Dissertations 2000 - 2009
Robert Browning's dramatic monologues often characterize the darker aspect of romantic love through speakers who demonstrate their devotion to violence. Exploring the innovations in discourse, Browning gives his narrators voices that allow them to speak from an ancient literary tradition. For Browning's speakers, words make the silencing of the lover either the act of ultimate devotion or the result of disappointed expectations. The narrator speaks of the absence of God, as when Porphyria's lover holds her body to him: "and yet God has not said a word!" With the poet's strong speech---in all his attractiveness, his destructive display of love …
