Despite the beliefs of modern Americans, the people of the North did not unanimously support the Civil War. Instead, peace demonstrations and draft dodgers abounded, threatening to undermine public morale. The war confronted the people with a choice between peace and Union. When the war appeared to fail in its objective of restoring the Union the people more readily accepted the idea of a negotiated settlement, but victory restored morale and encouraged them to continue the fight.

Show moreDespite the beliefs of modern Americans, the people of the North did not unanimously support the Civil War. Instead, peace demonstrations and draft dodgers abounded, threatening to undermine public morale. The war confronted the people with a choice between peace and Union. When the war appeared to fail in its objective of restoring the Union the people more readily accepted the idea of a negotiated settlement, but victory restored morale and encouraged them to continue the fight. Ultimately, sentiment for Union overcame the desire for peace, so the North remained committed until it defeated the rebellion.

- Abstract/Description
-
Since the late nineteenth century, scholars and historians have attributed the growth of a sensational press in Britain to long-term societal changes such as the rise of capitalism. What has been ignored, however, is the importance of individual initiative, mainly that of W. T. Stead of the Pall Mall Gazette. During the Sudan Crisis of 1883-1885, Stead introduced a new type of journalism to England that combined typographical innovations, such as maps and striking headlines, with a lively...

What has been ignored, however, is the importance of individual initiative, mainly that of W. T. Stead of the Pall Mall Gazette. During the Sudan Crisis of 1883-1885, Stead introduced a new type of journalism to England that combined typographical innovations, such as maps and striking headlines, with a lively literary style. At the root of this new type of reporting were Stead's deep-felt convictions about spreading Christianity, extending the empire, and improving the world through newspapers.

Show moreGrowth management grew as a concept and policy objective in the 1970s and 1980s. The interrelationships of the state and local governments changed when Florida developed growth policy and local government implemented the policy. Nine mandatory elements to be included in a local comprehensive plan and seven mandatory concurrency elements of the 1985 Florida Growth Management Act were expensive elements for local government to implement. As a result, the issue of funding the impacts of growth drove the growth management agenda, leaving the question of compliance. The question is: Did Florida local government comply with the transportation concurrency element of the Florida Growth Management Act? This dissertation analyzed five Florida counties and two Georgia counties to determine whether there was compliance with their respective state transportation policies. The study purposely looked at counties in different stages of growth to determine if the transportation requirements of the Florida Growth Management Act and the Georgia State Planning Act affected local budgets. Transportation is the most expensive element in local government budgets. Development orders would cease without the road capacity to carry the impact of proposed developments, making transportation the linchpin to state growth policies. A visual analysis and a multiple regression analysis were used to evaluate local government compliance with state transportation policy. A two-stage numerical evaluation was used for the visual analysis. The analysis looked for a slope change, a break in the trend, or both, after the impact of the intervention of the interrupted time series. A multiple regression analysis calculated the regression coefficient for a before and after dummy variable. The multiple regression removed the effects of population, interest rates, and road expenditure variables and isolated the effect of the dummy variable to determine local government compliance.

Show moreFlorida's population growth has been spatially and temporally uneven. Significant growth occurred in different regions of the state during certain periods of time. This differential growth was a result of specific socioeconomic conditions that varied both temporally and spatially. Florida was granted statehood 1845 and served as the southern extension of the plantation system. Growth was high in the northern regions of Florida during the antebellum years. After reconstruction, railroad infrastructure was developed that connected the distant reaches of the state with each other and the rest of the country. This facilitated the growth of the central regions of the peninsula. The construction of roads and the popularity of the automobile brought settlers and land developers to the southern regions of Florida in the early twentieth century. After a growth slump during the Depression, activities of World War II once again stimulated growth in the state, especially in the southeastern peninsula. The recent phenomenon of elderly migration has shifted growth to the less populated areas of the southwestern peninsula.

I conducted a foraging habitat use and selection study, which indicated that Wood Storks from coastal colonies, Paurotis Pond and Rodgers River Bay, require a narrow range of water depths in the mangrove-saltwater marsh ecotone near their colonies as well in the freshwater marsh habitats of the inland Everglades. Wood Storks nesting at the inland colony, Tamiarni West, relied heavily upon nearby freshwater marsh habitat and selected foraging sites associated with shrub swamp habitat as well as optimal water depths. The observational nesting ecology study of Wood Storks showed marked differences in parental nest attendance and food delivery rates between the two years of study, 2005 and 2006, which had different hydrological patterns.

Show moreThe history of automobile insurance in Florida provides a case study of economic adaptation to the negative consequences of rapid technological change. The emergence of the automobile in early twentieth century Florida brought with it widespread bodily injury and property damage. The insurance industry and the state government interacted for several decades in trying to fashion a way of reducing the economic cost of automobile accidents. Florida resisted a comprehensive application of insurance to the problem until 1971, when it passed the Florida Automobile Reparations Reform Act. Had Florida acted sooner, the economic impact of automobile accidents could have been greatly mitigated.

This thesis investigates some of the flow control issues in a system of Local Area Networks consisting of multiple token rings interconnected through bridges via a backbone ring. Flow control is realized by a window mechanism, i.e., a sender is permitted to transmit not more than a fixed number, W (the window size), of frames without having to wait for an acknowledgment. The solution is based on an existing approximation of the mean end-to-end delay in a stand-alone token ring LAN, which is...

Flow control is realized by a window mechanism, i.e., a sender is permitted to transmit not more than a fixed number, W (the window size), of frames without having to wait for an acknowledgment. The solution is based on an existing approximation of the mean end-to-end delay in a stand-alone token ring LAN, which is extended by approximating the arrival rates at the bridges as a function of the throughput of each subnetwork and the probability that, the throughput is directed to the other subnetworks. The packet-lengths are assumed to be exponentially distributed. The performance of the system is evaluated by varying the window size.

At low stringency (p=0.70), the populations cluster into several unknown clads with early divergence, indicating the presence of novel well established bacterial groups. Members of phylum Bacteroidetes, Firmicuites and Proteobacteria were identified, with the latter being the most prevalent in culture. Diversity indices rank Hollywood beach > Fort Lauderdale > Hobie beach. Taxonomic representation indicates marine water as more diverse compared to dry sand and wet sand. A combination of phylogenetic markers will be needed to define the immense diversity of this niche.

Show moreThis dissertation assessed two aspects of entrepreneurial scanning related to new ventures. The first was the information search and analysis these entrepreneurs performed when they made certain basic decisions necessary to start most business prior to commencement of operations. The second was the ongoing information search activities of entrepreneurs who had started childcare businesses and were managing them in their first few years of operation. In addition, this dissertation assessed the extent these scanning activities were consistent with a dual process theory of reasoning. Finally, the limitations of the study and suggested future research directions for research of entrepreneurial scanning were discussed. The results suggest an entrepreneur's scanning behavior at the start of the business may be different from scanning behavior that occurs once the business has been operating for a period of time. The need for cognition, exposure to statistical thinking and intelligence (operationalized in this study as the amount of formal education) were positively related to the kind of information search and analysis undertaken by the entrepreneur at the startup of the business that Kahneman (2003) and others describe as System 2 reasoning. The accessibility of information and the amount of formal education were positively related to scanning that was done in periods subsequent to startup by these childcare entrepreneurs. Work-family conflict was negatively related to scanning during this period.

This thesis employs the main principles of Environmental Archaeology while utilizing Geographic Information System technology to analyze the distribution of Paleoindian and Archaic period sites in south Florida. The following research demonstrates populations preferred certain areas to others, and environment played a considerable role in this preference, as indicated by the patterns that arose when site locations were analyzed based on environmental variables. These patterns in site locations were used to determine the most likely and least likely areas of south Florida for finding new archaeological sites. This thesis also provides an evaluation of the varions environmental and archaeological data sets used, concluding that paleoenvironmental reconstruction is a worthwhile goal, greatly enhancing modern environmental data sets used in this study.

Show moreThis dissertation discusses umbral calculus and lattice path enumeration and then continues by explicitly enumerating weighted directed lattice paths staying above a boundary using finite operator calculus. In Part I we discuss the history and representative results of the two topics. We separate umbral calculus into two fields, classical umbral calculus and finite operator calculus, and attempt to correct their intertwined histories. We discuss the beginnings of lattice path enumeration and survey the types of lattice path enumeration problems and solution methods found in the literature. In Part II, we give necessary conditions of a step set or of its equivalent operator equation such that the path count functions coincide with Sheffer polynomials where the path counts are nonzero. We derive the polynomials from an expansion theorem that includes a polynomial basis and initial conditions. The polynomial basis is derived from a known basic sequence with a transfer formula and a linear operator equation based on the step set. The initial conditions are functionals on the polynomials designed to vanish when evaluated along the boundary line for all but finitely many values. We solve lattice path enumeration problems with four types of boundary conditions and various step sets. We work out general solutions for paths that stay in the first quadrant, paths that stay in the first quadrant and above a line with an integer slope, and paths that can reach the boundary with an additional privileged access step set. We count the number of paths, and in one example we count the paths refined by the number of times they contact the boundary. We explore step sets including a general three-element step set, weighted finite step sets, weighted infinite step sets, and step sets that include paths as steps called pathlets. We research if our methods still give explicit solutions as we complicate and expand the step sets. The example sections include fourteen explicitly worked out problems. Part II of the dissertation includes and extends the three papers on the subject by Humphreys and Niederhausen written between 2000 and 2004.

I analyze the rhetorical effect of enthymemes in a select number of Oneida ads beginning in 1900 and continuing through the 1990s. This chronological progression demonstrates the gradual development of what I term, an enthymematic magazine ad. In this type of advertisement, the headline and the image work together to evoke certain emotions in readers leaving them to complete the message by providing information that is well-known by the target audience. The added effort on the part of readers makes the ad memorable and in fact induces readers to persuade themselves of the possible benefits of the advertised product---in this case Oneida silverware.

Show moreFailure of prestressed steel tendon in concrete due to corrosion or environmental cracking (or both) has become a major technological concern because of increased utilization of this form of construction in corrosive exposure such as coastal bridge deck structures. At the same time cathodic protection has evolved as the most practical means for arresting corrosion of reinforcing steel in existing structures. This technology also applies to pretensioned tendons. However, concerns have been raised that cathodic protection might cause embrittlement, since yield stress of these materials is relatively high. For the purpose of analyzing this embrittlement tendency a series of constant load and slow strain rate experiments were performed and the data evaluated. Influence of potential, chloride concentration, pH and precharging on the cracking susceptibility have been evaluated. The cracking process has been explained based on test results and SEM analysis.

Show moreThe community college system has been charged with providing open access to education for those who would otherwise be unable to obtain higher education, and with maintaining high educational standards at the same time. In an attempt to reconcile these disparate goals, the State of Florida legislated, beginning in 1985, entry-level testing and placement into remedial courses for those scoring below legislated cut-off scores. Remedial education, if effective, should result in increased student success. When the student success rates of a pre-legislation cohort are compared to students from a post-legislation cohort, they have not increased. Instead, declines are seen in graduation, retention in good academic standing, and the number leaving the college in good academic standing. These declines were not greater for minorities than for white students. The "cooling-out" function of community colleges is enhanced by the process.

Show moreDeterioration of reinforcing steel in concrete structures due to rebar corrosion is of national and international concern. Cathodic protection has evolved as the appropriate mitigating technique for existing structures. Another method which is being investigated is the electrochemical removal of chlorides from concrete. The current density used for this process leads to steel potentials at which hydrogen evolves. This raises concern regarding hydrogen embrittlement of reinforcing steel in concrete. For the purpose of analyzing this embrittlement tendency, a series of constant extension rate experiments was conducted in saturated calcium hydroxide solutions using notched and smooth specimens. While notched specimens did not show any effect of hydrogen embrittlement, the smooth specimens have revealed a reduction in ductility at high current densities. Experiments have shown that this loss in ductility is recoverable. Tests were also conducted on mortared smooth specimens which essentially exhibited the same trend observed as in the calcium hydroxide solution. The loss in ductility has been attributed to the enhanced void development in the presence of hydrogen during plastic deformation.

Show moreEndogenous 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 coast. On the west coast, females are exposed to "mixed" tides; most release their larvae during the day or night (early summer), or during the day (mid- to late summer). On the east coast, females are exposed to "semidiurnal" tides; they release their larvae between dusk and midnight. After four weeks of exposure to the East Coast tides, crabs from the West Coast showed hatching rhythms identical to the resident crabs. This change indicates that the crabs show behavioral (phenotypic) "plasticity". These observations provide further evidence for the adaptive value of behavioral plasticity.

How is such employment secured? Recommendations were made for improvement in method and content of courses as well as curricular revision based on data gathered from the respondents and administrators at Broward Community College.

This study investigates the technical feasibility of solar pond power generation in the state of Florida. A onedimensional model is used to analyze three different modes of operation of the pond as follows: The steady state analysis determines the maximum overall efficiency of the pond, optimum load and optimum brine temperature to be extracted. The steady periodic analysis determines the performances of the pond subjected to seasonal variation. The transient analysis determines the time...
Show moreThis study investigates the technical feasibility of solar pond power generation in the state of Florida. A onedimensional model is used to analyze three different modes of operation of the pond as follows: The steady state analysis determines the maximum overall efficiency of the pond, optimum load and optimum brine temperature to be extracted. The steady periodic analysis determines the performances of the pond subjected to seasonal variation. The transient analysis determines the time necessary for the pond to reach the optimum temperature. The study determines that for the Miami, Orlando, and Jacksonville locations, for a pond with 1.5 m NCZ depth using data for the state of Florida, the maximum overall efficiency is between 3.30 and 3.32 percent with an optimum load between 33 and 35 W/m2 and brine temperature to be extracted between 85 to 92°C. The above results assume that the power plant efficiency would be equal to that of a Carnot cycle efficiency. Since, in practice Carnot efficiency cannot be achieved the actual efficiency will be lower than the above values.
