Title: RECIPROCAL PERCEPTIONS BETWEEN ADMINISTRATIVE PERSONNEL IN SELECTED PUBLIC AND INDEPENDENT SCHOOLS (FLORIDA).
Creator: GARTEN, RICHARD M., Florida Atlantic University, MacKenzie, Donald G.
Abstract/Description: This dissertation focuses attention on the ways in which public and nonpublic school administrators view socio-educational principles, their own and one another's schools, and the ways in which schools could share rather than compete. After an introduction which finds American and Floridian cultural pluralism and educational dualism to have been transplanted by early colonists, the dissertation describes the method by which the data were gathered: a thirty-four item, open-ended questionnaire...
Show moreThis dissertation focuses attention on the ways in which public and nonpublic school administrators view socio-educational principles, their own and one another's schools, and the ways in which schools could share rather than compete. After an introduction which finds American and Floridian cultural pluralism and educational dualism to have been transplanted by early colonists, the dissertation describes the method by which the data were gathered: a thirty-four item, open-ended questionnaire which was completed by twelve public school and twenty private school administrators and officials largely in two Florida counties--Palm Beach and Broward. The data suggests that while there is general agreement for parental choice in education within both groups and general agreement about the "propriety" of four types of schools (public, independent, church-related, and proprietary), there are misunderstandings, hostilities, tensions, and territorial imperatives at work in day-to-day relationships. The problems of money, certification of teachers and administrators, and defensiveness run through the respondents' views. Areas of school functioning on which the two sectors generally agree include the right of citizens to open new schools, the threat of revenue loss, rejection of the proposed voucher system, public progression based on merit, local accreditation of private schools, and the need to check contract-status prior to engaging a teacher. Other matters are major or minor bones of contention between private and public school leaders: elitism, the problem of brain drain, white flight schools, the place of religion and state-devised curricula, teacher certifications and the right of teachers to move freely from one sector to another, and the transfer of students' records. Because evidence suggests that there is increasing cooperation between public and private school leaders at the national and state levels and no clear progress at the county level, the dissertation concludes with a recommendation that the dominant university in the area extend its interest in the relationship between the sectors and plan bridges to increasing cooperation in the interest of a quest for excellence shared by public and nonpublic schools and their leaders.

Title: Institutional Distance, Social Capital, and the Performance of Foreign Acquisitions in the United States.

Show moreThis dissertation examined the roles of institutional distance and corporate social capital in the unique context of foreign acquisitions in the United States. A conceptual framework was developed which suggests that institutional distance has a dual impact on international acquisition performance. Institutional distance makes it more difficult for foreign acquirers to establish legitimacy in the United States, and therefore adversely affects acquisition success. Institutional distance also has a beneficial effect on acquisition performance to the extent to which it provides valuable opportunities for institutional arbitrage. Corporate social capital was discussed as a strategy to aid foreign MNCs in overcoming the detrimental, and leveraging the beneficial effects of institutional distance on these cross-border transactions. Analysis results based on a sample of 247 large-scale acquisitions in the US by publicly traded foreign acquirers that were made between 2000 and 2005 provided overall support for the hypothesized model. It was found that each of the three dimensions of institutional distance - regulatory, normative, and cultural distance- was negatively associated with the local media endorsement of foreign acquirers. Furthermore, regulatory distance was negatively associated with the investment ratings of foreign acquirers, and normative distance had a positive impact on the number of local lawsuits filed against these firms. Results from this study also showed that the existence of corporate social capital aided foreign acquirers in overcoming the negative effect of regulatory distance on both the firms' investment ratings and their local media endorsement. The findings further revealed that media endorsement of foreign acquirers in the United States was positively related to acquisition performance as indicated by cumulative abnormal returns. Moreover, legitimate foreign acquirers with high investment ratings were able to leverage cultural distance, given that the relationship between investment ratings and acquisition performance was positive for this group of acquirers. The results reported in this study therefore emphasize the importance of organizational legitimacy and corporate social capital for international acquisition performance, and shed light on the detrimental and beneficial roles of institutional distance in this context. In so doing, this dissertation strengthens institutional theory and social capital theory as powerful perspectives in international strategic management.

Variables investigated were survey participants' status: faculty or student. The subjects of this study were 225 students and 129 faculty members of Port St. Lucie High School in St. Lucie County, Florida. The critical incidents were compared between Port St. Lucie High School which implemented the program and another comprehensive high school in St. Lucie County. The findings showed two major results: (a) although there was some increase in positive perception about school climate after the implementation of the conflict resolution/peer mediation program, it was not significant and (b) there was a decline in the rate of three of the disciplinary incidents measured, attempting to fight, fighting and striking another student were less than expected. Disrespect for others, however, was not decreased.

Show moreMultiple tracers, such as DO, ammonia, TN, TOC, E. coli, TC, and Enterococcus were analyzed in order to identify and characterize trends in coastal water quality. This study focused on three factors; wastewater disposal and treatment alternative; season; and human population density. Samples were collected in representative sites of urban Broward County and of rural Taylor County, FL, for pair-wise comparison. Sites included areas connected to the public sewer network and served by on-site treatment and disposal system (OSTDS). Sampling activities were conducted through seasonal low and seasonal high water table elevation (SLWT and SHWT), and always on slack to outgoing tide. Different statistical tests were performed, including: t-Tests, correlation analysis, principal component analysis (PCA), and analysis of variance (ANOVA). Results suggested that water quality is lower: in urban sites compared to rural sites; in OSTDS sites compared to sewered areas; and SHWT compared to SLWT.

Show moreThis qualitative study furthers understanding of psychological contract violation experiences as examined through the lens of administrative middle managers in higher education settings. Psychological contract is defined as unstated expectations in the employment relationship which, when violated, results in negative outcomes for employers and employees. In higher education, middle managers are professional staff with titles such as director, associate director, or assistant director across academic and student affairs units. The purpose of this phenomenological study was to explore the meaning of violation experiences for administrative middle managers in higher education settings. This study advanced understanding of post-violation outcomes on participants’ work and future career intentions. This study found that participants’ psychological contract violation experiences had a wounding effect, including negative emotional impacts, feelings of isolation, increased vulnerability, and feelings of responsibility for the violation experience. In addition, participants made sense of their violation experience by focusing on their passion for serving students, the importance of work to their identity, and the responsibility they felt as leaders. Study participants remained in their work settings despite the violation experience and negative impacts. This study resulted in implications for practice for three entities: higher education institutions, administrative middle managers, and professional associations.

Show moreRetaining business value in a legacy commercial enterprise resource planning system today often entails more than just maintaining the software to preserve existing functionality. This type of system tends to represent a significant capital investment that may not be easily scrapped, replaced, or re-engineered without considerable expense. A legacy system may need to be frequently extended to impart new behavior as stakeholder business goals and technical requirements evolve. Legacy ERP systems are growing in prevalence and are both expensive to maintain and risky to evolve. Humans are the driving factor behind the expense, from the engineering costs associated with evolving these types of systems to the labor costs required to operate the result. Autonomic computing is one approach that addresses these challenges by imparting self-adaptive behavior into the evolved system. The contribution of this dissertation aims to add to the body of knowledge in software engineering some insight and best practices for development approaches that are normally hidden from academia by the competitive nature of the retail industry. We present a formal architectural pattern that describes an asynchronous, low-complexity, and autonomic approach. We validate the pattern with two real-world commercial case studies and a reengineering simulation to demonstrate that the pattern is repeatable and agnostic with respect to the operating system, programming language, and communication protocols.

Show moreIn Florida, mangroves have responded to climate change by slowly migrating northward into traditional salt marsh habitat. However, little is understood about the relationships among mangrove growth form plasticity and environmental conditions. In addition, the effects of the mangrove northward expansion on pre-existing salt marsh communities are unknown, especially any influences of differences in tree morphology. The size, canopy structure, and root structure of the three mangrove species Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa were measured at six sites along the east coast of Florida. Structural equation modeling was used to evaluate the multivariate relationships between environmental and biotic variables. Mangrove growth form varied widely with environmental variables. The results of this study suggest that R. mangle expansion into salt marsh may rely on interactions with salt marsh and shading as well as on climatic variables, which has implications for future mangrove expansion northward in Florida.

This study focuses on quantifying the factors that impact the micro-environment of leachate; and microbial activities that help the precipitates to form and attach to the LCS. It also evaluates the performance of operational changes that have been implemented or the potential alternatives and recommends the possible measures to reduce the severity of clogging. A field scale side-by-side pipe network, and several laboratory setups were used in this study. Calcite is identified to be the predominant phase present in the precipitates using XRD/XRF analysis which, concur with the previous studies. Microbial growth and activities enhance the precipitation of CaCO3 in LCS. Clogging in LCS pipes can be controlled if not eliminated by continuous monitoring along with frequent cleaning with physiochemical processes.

Show moreThis dissertation investigates two fundamental questions related to how well exchange-traded funds that hold portfolios of fixed-income assets (bond ETFs) proxy for their underlying portfolios. The first question involves price/net-asset-value (NAV) mean-reversion asymmetries and the effectiveness of the arbitrage mechanism of bond ETFs. Methodologically, to answer the first question I focus on a time-series analysis. The second question involves the degree to which average returns of bond ETF shares respond to changes in factors that have been found to drive average returns of bond portfolios. To answer this question I shift the focus of the analysis to a cross-section asset pricing test. In other words, do bond ETF share prices track the value of their underlying assets, and are they priced by investors like bonds in the cross-section? The first essay concludes that bond ETF shares exhibit mean-reversion asymmetries when price and NAV diverge, along persistent small premiums. These premiums appear to reflect the added value that bond ETFs bring to the fixed-income asset market through smaller trading increments, greater liquidity, and the ability to buy on margin and sell short. The second essay concludes that market, bond-specific, and firm-specific risk factors can help to explain the variation in U.S. bond ETF average returns, but only size seems to be priced in the cross-section of expected returns. This is not surprising as the sample used in the asset pricing tests is limited to the period 2007-2010, which corresponds to the "great recession", and size has been interpreted in the asset pricing literature as a state variable that proxies for financial distress and is highly dependent on the phase of the real business cycle., The two essays together suggest that bond ETFs can be used in trading strategies based on taking long and short positions in fixed-income assets, especially when trading in portfolios of fixed-income assets directly is not feasible.

Teleost species lack electrosensory systems and development of technologies which target the ampullary organs of sharks provides an avenue to selectively deter elasmobranchs without affecting the catch rate of target teleosts. Electric field measurements and a controlled scientific longline study were conducted testing whether the lanthanide metal neodymium or zinc/graphite might reduce elasmobranch catch per unit effort (CPUE). Baited longline hooks were treated with neodymium and zinc/graphite and catch rates were compared to that of controls. Shark CPUE decreased by 60% on neodymium treated hooks and 80% on zinc/graphite treated hooks. The effectiveness of both treatments varied among species with significant reductions shown for Atlantic sharpnose sharks (Rhizoprionodon terranovae) but less dramatic differences for others. Zinc/graphite is potentially a viable tool for reduction of shark bycatch in a commercial longline fishery.

Show moreCoral reef declines, particularly in coastal zones, have been linked to thermal stress and anthropogenic impacts on water quality. St. Lucie Reef near Stuart, Florida receives increased estuarine efflux as a result of watershed changes and management policies that have substantially altered historic, natural flows. This research used ambient and elevated temperatures (25°C and 30°C, respectively), and offshore versus St. Lucie Estuarine discharge water to investigate the individual and interactive effects of thermal and water quality stress on Montastraea cavernosa, a dominant scleractinian coral species at St. Lucie Reef. These goals were accomplished using ex-situ, factorial, experimental design that was supplemented with existing in-situ monitoring on St. Lucie Reef. Zooxanthellae density and chlorophyll content were evaluated to determine effects on the corals and their symbionts. Zooxanthellae populations were significantly affected by thermal stress. Significant interactions between temperature and water treatment were observed, suggesting that the impacts of discharge water may be supplanted when corals are exposed to thermal stress. In a supplement to the experiment, M. cavernosa colonies transplanted from Palm Beach to St. Lucie Reef demonstrated resilience despite exposure to more variable environmental conditions. Collaborative partnerships with multiple state agencies and local government offices facilitated data sharing to inform decision making for South Florida’s resource management strategies. Creating effective resource management is crucial for the conservation of coastal ecosystems impacted by land-based sources of pollution both locally and globally.

Twenty women and men (aged 18-50 years) participated in the study. Participants completed a yoga plus relaxation (YR) session and a relaxation only (R) session. The YR condition showed significant changes from baseline in HR (bpm, p < 0.001), RR (ms, p < 0.001), pNN50 (%, p = 0.009), LF (% p = 0.008) and HF (% p = 0.035). The R condition showed significant changes from baseline in HR (bpm, p < 0.001), RR (ms, p < 0.001), HF (ms2, p = 0.004), LF (%, p = 0.005), HF (%, p = 0.008) and LF/HF (%, p = 0.008). There were no significant differences between conditions for the changes from baseline for any of the variables. The results demonstrate that relaxation produces favorable changes in indices of heart rate variability whether alone or preceded by about of Hatha yoga.
