Show moreThe objective of this thesis is to understand and describe the geographic properties of regional malls in Broward County, Florida. The paper investigates the unique character of regional malls and defines regional malls in South Florida as atypical of the industry standard. First, the various definitions of "regional mall" are presented. The history of the diffusion of shopping centers in the United States and the expansion of malls in Southeast Florida is described. A review of the principal theories of central place systems and the location and classification of malls is provided. The shopping centers in Broward County and their market area characteristics are discussed. The internal store placement within each mall is examined. Broward regional malls are much larger for their trade areas than the industry standard.

Results indicate that sexually mature female rabbits have a significantly higher expression of TL than sexually mature male rabbits. TL expression was higher in sexually mature rabbits than the juvenile rabbits. No significant difference was seen among the juvenile female and male rabbits. Rabbits were also sham operated, ovariectomized and ovariectomized followed by either estrogen or androgen treatment. Androgen treated rabbits expressed significantly higher amounts of TL when compared to the other groups. This study also focused on sex hormone regulation of the gelatinases MMP-2 and MMP-9. All four treated groups expressed MMP-2, but the estrogen treated rabbit showed the highest expression; however, only the estrogen treated rabbit expressed MMP-9 and no expression was seen in the other three groups.

Show moreThe design of paper currency has attracted attention recently with the introduction of the Euro and American currency design modifications. New designs provide deterrence against counterfeiting, and, in some cases, accommodate the special needs of visually challenged individuals. Often aesthetics are given lower priority or ignored completely. This thesis is an examination of the author's motivations, inspirations, goals and design decisions involved in creating a set of paper currency bills that fit the high-tech, fast-paced and culturally diverse society that is twenty-first century America. The author incorporates a deep visual texture with American symbols and historical events illustrated by shape and shading alone---no color or line. Semiotics and visual metaphors are applied to convey meaning to abstract or complex concepts. Counterfeit deterrence features and features for use by visually challenged individuals are integrated into the design, thus producing a system of currency that is both functional and aesthetic.

Show moreHerbal medicine, the role of indigenous healers in health maintenance, ethnomedical ecology, and the impact of westernization on the traditional medical system of the Biminis, Bahamas, are investigated from several perspectives. Herbalists' socio-clinical role, botanical pharmacopoeia, and medicament preparation processes are qualitatively described, quantitative data being presented for the latter. Edited interview transcripts supplement findings stated in the text. Fifty-six plants are reported whose medicinal usage is undocumented for the Bimini people. Statistical evaluation of herbalists' hand-and-eye measurement techniques (n=150) indicates maximum error from respective remedy means is less than 10%. Chemical constituents of positively identified medicinal species are reported and indicated as medically therapeutic and/or toxic in physiological activity. Some remedies are pharmacognostically appraised through the literature. Quantitative analysis of remedy preparation processes suggests herbalists' procedures may significantly reduce potential medicament toxicity, average reduction for the target compound of this study being 96.5% for decoctions.

In the Raman experiments, the Cu(1)-O(1) c-axial Ag stretching mode at ~502cm^-1 was investigated extensively at temperatures ranging from 23K to 773K. The room-temperature Raman spectra indicated a trend for saturation in frequency shift (as a function of iron concentration). This was interpreted as evidence supporting the occurrence of a type of iron clustering in the (001) basal plane. Effects of such a cluster formation upon the mechanism of superconductivity were considered. The low temperature Raman spectra show that the 502cm^-1 mode frequency increased slightly with decreasing temperature for all of the studied values of iron concentration without exhibiting any anomalous behavior. In the high temperature Raman spectra, a significant softening of the 502cm^-1 mode, indicative of a phase transition onset, was observed.

It was a burial mound with scattered human skeletal fragments on the surface. The salvage excavation had to be expedited due to the fact that a building development on the site was in progress. Iscan and Gomez (1982) suggested that there were skeletal elements recovered that provided evidence for the existence of Paget's disease (Osteitis deformans ) in the population. However, this study reanalyzes the elements and using new technology such as Computed Tomography scans shows that there was no conclusive evidence of Paget's disease. Instead, the skeletal morphology of the affected bones is comparable to the characteristics of treponemal disease which, unlike Paget's disease, is found in sites contemporaneous to Briarwoods.

Show moreMaturing baby boomers are moving into prime giving years and, if history repeats itself, this generation will change the "philosophy of giving." These aging baby boomers will amass significant wealth either through inheritances or their successful businesses. It is therefore critical that professional fundraisers identify how to effectively communicate with the affluent members of this generation to develop them into major donors. Using a qualitative approach through in-depth interviews, this research examines characteristics and traits of baby boomers, identifying seven common themes that can be used to develop communication strategies. It concludes that affluent baby boomers demand accountability from charitable organizations and value meaningful experiences. They are focused on personal accomplishments and are deeply family oriented. Messages must be concise and delivered by those respected by the donor. High-tech media are preferred.

Show moreA new turbulence model is proposed in this dissertation for two-dimensional incompressible turbulent flows. The methodology used in the present study is a unilateral-statistical-average scheme with the concept of orthotropic eddy viscosity. This methodology has never been explored before in any research work of this nature. The distinguished feature of the unilateral-statistical-average scheme, compared to Reynolds averaging, is that the first-order information of the fluctuating velocity field is retained. This is achieved by dividing the fluctuating velocities into two groups and applying the average only to a single group. It is proved that the mean value of the fluctuating velocities of the first group solutions is not equal to zero. This non-zero quantity, together with a specified length vector, is used to define a 3 x 3 matrix of orthotropic eddy viscosity. In an off-streamline coordinate system, the eddy-viscosity matrix exhibits anisotropy characteristic, where each component of the turbulent stresses is related to all the components of the rate of strains of the mean fluid flow. The present model has been successfully applied to turbulent boundary-layer flow, turbulent free-shear jet flow, and turbulent wall-bounded separation flow without using empirical constants or wall-functions. Good agreements between the numerical results and experimental data or empirical predictions demonstrate that the unilateral-statistical-average scheme and the orthotropic non-linear eddy-viscosity formulation are robust and efficient in modeling basic turbulent flows. Applicability and predictability of the model to more complex engineering turbulence problems are worthy of further investigation in the future research.

Show moreThis thesis considers two important issues in wireless networks. In first part, we address Energy-Efficient Range Assignment in Heterogeneous Wireless Sensor Networks (HRA) and in second part, we present a survey on security attacks in ad hoc wireless networks. We address the HRA problem by selecting the transmission range for each energy-constraint sensor node such that a multi-hop communication path exists between each sensor' node and a resource-rich supernode while maximum power required is minimized. This is the first work to address this problem. We propose several solutions: an Integer Programming approach, a distributed greedy protocol, and a minimum spanning tree protocol based on clustering. In second part of this thesis, a survey is carried out on security attacks on routing protocols in ad hoc wireless network. We examine and classify major routing attacks and present a comprehensive survey on the state-of-the-art mechanisms and solutions designed to defeat such attacks.

Show moreThe history of Western thought is permeated by a dualistic habit of mind which prevents a deeper connection with that primordial world mediated by myth and archetypes. Nietzsche described this dualism as the imposition of rationalistic Apollonian values on the far older tradition of intuitive Dionysian modes of being. Extending this concept further, James Hillman describes this same phenomenon as a lack of soul which he calls psyche. Without a reconnection to psyche, Western civilization is schizoid and incomplete. Using these insights as a basis for critical exploration, this thesis examines Archibald MacLeish's 1954 poem cycle Songs for Eve and its inversion of the traditional Western archetypes of the Fall and woman's role in it. By rejecting the traditional Western allegorical interpretation and reinstating the older Dionysian understanding of the Fall, MacLeish awakens the reader to a new and deeper understanding of this pervasive mythic motif.

All 8 wt.% yttria samples showed mostly the tetragonal structure at room temperature. Three of the four 8 wt.% yttria samples exhibited the tetragonal structure at elevated temperatures, while no conclusion was inferred for the powdered sample. As compared with yttria, ceria is a less effective stabilizer with respect to the zirconia tetragonal structure. A monoclinic transformation between 400 K and 800 K was observed in the 4 wt.% yttria sample which had been processed by rapid quenching. Adding alumina to 4 wt.% yttria did not completely stabilize the tetragonal structure at or above room temperature, making it a less effective stabilizer than yttria or ceria. The phase transformation was responsible for the unusual values in the Gr uneisen parameters obtained for the 4 wt.% yttria sample.

No specialized equipment or training is required. MAbs were also produced against serum albumin purified from white marlin (Tetrapturus albidus) and Atlantic blue marlin (Makaira nigricans). These Mabs were examined for their utility in identification assays for these species.

It also confronts ideals embedded in culture and society that have become points of emotional conflict for many. This collection often focuses on successfully communicating feelings and ideas through the brevity of language. However. at some points it is necessary to set aside the practice of brevity and lengthen the works in order go beyond restrictive bounda ries and enter a realm of continuation, control, and repetition. Many of the poems begin without beginnings and end without resolutions both allowing the reader to draw from it personal points of reference as well as conclusions. An anatomical theme can be found throughout this collection, allowing these poems to become living things while lending a sense of mysticism. Collectively, these poems try to achieve a relationship of familiarity with the reader while still having come from a personal space.

By studying the predictions of DOP values using Pathfinder Office and performing some statistical analysis on theoretical GPS data using the software SAS 8.0, the conclusion was made that PDOP values not only depend on the number of available satellites, but also on their relative positions. By field testing, and comparing the recorded data with the theoretical GPS data, it was seen that non-DGPS could be rather accurate. Furthermore, it can be justified for a GPS unit to eliminate the Z coordinate measurement since vertical position errors are larger than horizontal errors, which may lead to improved accuracy. On the other hand, some 'visibility problems' were encountered while testing the GPS units under driving conditions. Different ways to compensate for this disadvantage were studied. In the end, the different features of the GPS unit were discussed and a way to improve the system was also proposed.

Show moreIn Florida, recent changes in legislation have granted community colleges the ability to now offer Baccalaureate degrees in education, frequently to non-traditional students. Additionally, teachers face more high-stakes tests than ever before, and often times struggle with the mathematics sections of such tests. A comprehensive literature review in the areas of pre-service teachers' math knowledge, teachers' efficacy beliefs about teaching math, and the high-stakes mathematics testing of teachers was conducted. Based on the information obtained from the literature review, the study examined a population of pre-service teachers in a new teacher preparation program in Florida. The research investigated relationships surrounding pre-service teachers' characteristics such as: ages, failed attempts on high-stakes math sub-tests, levels and grades earned in lower-division math courses, time elapsed between lower-division and upper-division math courses, and the grade earned in the math methods course, in relation to their efficacy beliefs about teaching math. Results from the study revealed that pre-service teachers' ages, levels and grades of lower-division math courses, and grades earned in the math methods courses, did have a significant relationship with their math efficacy beliefs, as measured by the Mathematics Teaching Efficacy Beliefs Instrument (MTEBI). The variables of failed attempts on high-stakes math tests, and the time elapsed between lower- and upper-division math courses, did not significantly correlate with pre-service teachers' MTEBI scores. Additionally, a multiple regression model including the previously mentioned variables did predict pre-service teachers' MTEBI scores greater than chance, although the model did not generalize to the greater population. The findings from this study can assist new teacher preparation programs, which may serve non-traditional students, in isolating variables that can identify pre-service teachers who are at risk for poor mathematical experiences and attitudes in the early stages of the program. If pre-service teachers are prone to negative beliefs about teaching math, then any information in assisting these students prior to their having an effect on math education for future students can be beneficial. While this study posits some avenues to pursue in fostering positive math beliefs and experiences in teacher preparation programs, recommendations for further research in this area also will be discussed.

Show moreWe have developed reliability models for a variety of fault-tolerant software constructs including those based on two well-known methodologies: recovery block and N-version programming, and their variations. We also developed models for the conversation scheme which provides fault tolerance for concurrent software and a newly proposed system architecture, the recovery metaprogram, which attempts to unify most of the existing fault-tolerant strategies. Each model is evaluated using either GSPN, a software package based on Generalized Stochastic Petri Nets, or Sharpe, an evaluation tool for Markov models. The numerical results are then analyzed and compared. Major results derived from this process include the identification of critical parameters for each model, the comparisons of relative performance among different software constructs, the justification of a preliminary approach to the modeling of complex conversations, and the justification of recovery metaprogram regarding improvement of reliability.

Poorly-developed or none-existent caeca occur in frugivorous, nectarivorous, piscivorous, and other carnivorous (those consuming carrion, some small vertebrates) species whose diets consist mainly of soluble sugars and proteins. There were no significant age or sex differences in caecal lengths of selected species and caecal lengths are not correlated with body mass. Caecal length does, however, correlate well with small intestine length in species that ferment cellulose and possibly chitin, and with large intestine length in species that are potentially waterstressed and/or consume a low protein diet. Caeca function in digestion of insoluble food and may help conserve critical resources such as water and nitrogen.

Reliability and risk assessment play an important role in product design, development and production. In mass production items, data is abundant and testing in product development and certification is usually thorough. In contrast, for nonparametric applications, product cost is high, there is limited production and the product is often used only once and discarded. In this type of manufacturing, data is usually limited because of the cost of testing. This makes reliability and risk...
Show moreReliability and risk assessment play an important role in product design, development and production. In mass production items, data is abundant and testing in product development and certification is usually thorough. In contrast, for nonparametric applications, product cost is high, there is limited production and the product is often used only once and discarded. In this type of manufacturing, data is usually limited because of the cost of testing. This makes reliability and risk assessments a difficult task. To circumvent this shortfall in data and its analysis, it is the intent of this paper to provide an alternative approach to models for reliability and risk analysis. This was accomplished by first surveying existing literature and models; then, approaching the problem with a set of block diagrams for each of the required analyses. Additionally, a full set of current models and failure analysis tools were also incorporated. With these tools the proposed methodology was demonstrated in case studies. These studies provided the validation for the methodology presented.

- Abstract/Description
-
This study examined domain-specific gender differences in children's domain specific theories of intelligence. It was based on Dweck's theory that individuals view intelligence as either fixed (entity theory) or flexible (incremental theory). The hypothesis that the mathematics and verbal domains would differ most for older, brighter girls who are highly sex-typed was confirmed in that more highly sex-typed older girls endorsed more entity-like thinking in the math area. Higher achievement...

It was based on Dweck's theory that individuals view intelligence as either fixed (entity theory) or flexible (incremental theory). The hypothesis that the mathematics and verbal domains would differ most for older, brighter girls who are highly sex-typed was confirmed in that more highly sex-typed older girls endorsed more entity-like thinking in the math area. Higher achievement level was related to more incremental thinking, with gender and domain effects found only among low and not high achievers. Theory interacted with age level in influencing English grades. Also, in terms of examining the effect of perceived competency on academic performance, academic and domain competency but not global self-esteem related to school grades. It was found that girls associated feelings of global self-worth to achievement test scores.
