A Distributed Quadtree Dictionary Approach To Multi-Resolution Visualization Of Scattered Neutron Data, Rion Dooley

LSU Doctoral Dissertations

Grid computing is described as dependable, seamless, pervasive access to resources and services, whereas mobile computing allows the movement of people from place to place while staying connected to resources at each location. Mobile grid computing is a new computing paradigm, which joins these two technologies by enabling access to the collection of resources within a user's virtual organization while still maintaining the freedom of mobile computing through a service paradigm. A major problem in virtual organization is needs mismatch, in which one resources requests a service from another resources it is unable to fulfill, since virtual organizations are necessarily …

Routes Of Freedom: Slave Resistance And The Politics Of Literary Geography, Judith Louise Kemerait

LSU Doctoral Dissertations

This dissertation integrates rhetorical, historical, and spatial analysis in an effort to expand our understanding of the cultural work performed by antebellum narratives that take slavery in the United States as their subject matter. Specifically, it focuses on the complicated relationship between place and human praxis as revealed in five texts: The Confessions of Nat Turner, Harriet Beecher Stowe’s Dred, Martin R. Delany’s Blake, Frederick Douglass’s “The Heroic Slave,” and Herman Melville’s Benito Cereno. In my attention to literary geographies, I trace spatial patterns in which considerations of organized resistance and slave rebellion are repeatedly placed in “wild-spaces” such as …

On Qualitative Properties And Convergence Of Time-Discretization Methods For Semigroups, Mihaly Kovacs

LSU Doctoral Dissertations

In this dissertation we use functional calculus methods to investigate convergence and qualitative properties of time-discretization methods for strongly continuous semigroups. Stability, convergence, and preservation of contractivity (or norm-bound) of the semigroup under time-discretization is investigated in a Banach space setting. Preservation of positivity, concavity and other qualitative shape properties which can be described via positivity are treated in a Banach lattice framework. The use of the Hille-Phillips (H-P) functional calculus instead of the Dunford-Taylor functional calculus allows us to extend fundamental qualitative results concerning time-discretization methods and simplify their proofs, including results on multi-step schemes and variable step-sizes. We …

Coastal Lakes Aquatic Plant Survey Report, Mary Pfauth, Mark Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Invasive, non-indigenous plants can degrade water quality and fish habitat when they invade lakes, ponds, and streams. Changes in plant community architecture in lakes due to invasion by canopy-forming invasive aquatic plants can result in loss of native plant biodiversity and reduction of the structural complexity of the underwater habitat. Differences in photosynthetic biochemistry between non-indigenous and native plants can result in large diurnal pH and dissolved oxygen concentrations.

Statistical Models And Genetic Evaluation Of Binomial Traits, Jose Lucio Guerra

LSU Doctoral Dissertations

Generalized mixed model methodology and MCMC simulations were used to estimate genetic parameters for calving rate and calf survival with the normal, probit, and logistic models. Calving rate and calf survival were defined as 0 each time a cow failed to calf or a calf failed to survive to weaning age, otherwise they were set to 1. Data were available on 1,458 cows and on 5,015 calves. Cows produced a total of 4,808 records over 4 discrete generations of rotational crosses between Angus, Brahman, Charolais, and Hereford from 1977 to 1995. The heritability of calving rate and calf survival, the …

Irrationality And Human Reasoning, Michael Aristidou

LSU Master's Theses

In his account of intentional interpretation, Donald Davidson assumes that people are mostly rational. Several psychological experiments though, reveal that human beings deviate drastically from the normative standards of rationality. Therefore, some psychologists arrive to the conclusion that humans are mostly irrational. In this thesis, I raise some objections to both points of view. On the one hand, ascribing rationality to humans in an a priori manner seems a suspicious position to adopt, considering the empirical data that show otherwise. On the other hand, the validity of the experiments and what exactly they test can also be put in question, …

Skill Acquisition And Transfer In A Simple Algebraic Task, Charan J. Singh

Theses : Honours

Speelman's (\999) finding that performance of a skill is based to some extent on the conter.t in which it is performed, rather than simply on the acquired skill itself, is not accounted for by the basic skill acquisition theories like ACT -R Theory or Instance Theory. The purpose of the current experiment was to examine whether the degree of change in context influences the degree of reduction in transfer. Forty participants were trained on an algebraic task and then tested in two different transfer conditions. Condition one included one new item and condition two included two new items in the …

Students' Perception Of Their First Experience Of The Sacrament Of Penance Within The Archdiocese Of Perth, Western Australia, Janine Sanzone

Theses : Honours

This study examined the perceptions of year three children of their first experience of the Sacrament of Penance within the Archdiocese of Perth in light of contemporary developmental research. In the Archdiocese of Perth, the Catholic Church's present practice is to prepare students to receive Penance in Year 3 when they have reached the "age of reason' (7 years). The theology behind the Catholic Church's decision to administer Penance at the age of reason is also investigated. The work of developmental psychologists, particularly Kohlberg and Fowler, underpins this investigation of the cognitive, moral and spiritual development of the sample population. …

Freshwater Macroinvertebrate Response To Wetland Acidification On The Swan Coastal Plain, Jill Woodhouse

Theses : Honours

Wetlands of the Swan Coastal Plain (SCP) are acidifying because extended drying periods have exposed and oxidised sulphidic sediments creating sulphuric acid and lowering wetland pH. This appears to be the ecological equivalent of both Northern Hemisphere acid rain in lakes and streams, and acid mine drainage. This research aims to describe the characteristic acidic macroinvertebrate faunal assemblage of the SCP by identifying acidophobic and acidophilic taxa, and to examine their potential as indicators of acidification for routine biological monitoring. Four linked approaches were used in the study - analysis of a database, investigation of acidified wetland case studies, wetland …

Social Competence : An Exploration Of Children's Experiences Within The Home Environment, Mandie B. Shean

Theses : Honours

The acquisition of social competence is an important developmental task for children. This review examines how child effects and environmental effects contribute to children's achievement of social competence. Environmental factors are addressed through Bronfenbrenner's (1999) ecological systems model of the microsystem, mesosystem and exosystem, The microsystem includes the home environment with parent-parent, parent-child and sibling relationships. The mesosystem includes the school environment with peer and teacher relationships. Finally, the exosystem incorporates indirect environments such as parent work, economic status and the media. Issues of reciprocal effects are addressed and the suggestion is made that social competence is the result of …

The Abject In The Technological Other, Alex Bradley

Theses : Honours

A photographic project and exegesis demonstrating artificial intelligence and artificial life as occurrences of the abject. In the photographic project '0=2', the technologies of artificial intelligence and artificial life are examined in relation to identity, via an elaboration of the psychoanalytic concert of the 'abject'. An exegesis of the creative project contains an investigation of computer technologies in regard to identity, an analysis of the basic concepts and paradigms of the sciences of artificial intelligence and artificial life, and an elaboration of the psychoanalytic concept of the abject - demonstrating A.l. and a-life as cultural instantiations of abjection. In addition, …

Influences On The Uptake Of Covenant Mechanisms For Nature Conservation On Private Lands In Australia, Thomas I. Kabii

Theses: Doctorates and Masters

Globally management agreements have emerged as more effective in assuring long-term nature conservation on private land, than regulatory mechanisms alone. Restrictive permanent covenants in particular, which are legally binding management agreements in perpetuity, have been adopted in most States and Territories in Australia. However, there is reluctance among landholders to take them up. Sound understanding of the factors that influence the decisions of landholders regarding the uptake of permanent covenants is important in planning and strategizing for increased covenant uptake. The aim of this thesis is to further this understanding and to support the design of a coordinated covenant mechanism …

Contrast Enhancement Of Ultrasound Images Using Shunting Inhibitory Cellular Neural Networks, Murali M. Gogineni

Theses: Doctorates and Masters

Evolving from neuro-biological insights, neural network technology gives a computer system an amazing capacity to actually generate decisions dynamically. However, as the amount of data to be processed increases, there is a demand for developing new types of networks such as Cellular Neural Networks (CNN), to ease the computational burden without compromising the outcomes. The objective of this thesis is to research the capability of Shunting Inhibitory Cellular Neural Networks (SICNN) to solve the clarity problems in ultrasound imaging. In this thesis, we begin by reviewing a number of traditional enhancement techniques and measures. Since the entire work of this …

An Investigation Of The Equity Premium Using Habit Utility And Equity Returns: Australian Evidence, Lurion De Mello

Theses: Doctorates and Masters

The gap between the return on stocks and the return on the risk free assets represented by bonds is named the 'Equity Premium' or 'Equity Risk Premium'. In the history of asset pricing models, one of the most serious problems for the equity premium is that the average equity premium is too large to be explained by standard general equilibrium asset pricing models. Researcher's have tried to use variables such as dividend yield's to explain the gap between stocks and bonds with mixed results. After retrieving around a one percent equity premium with the most standard consumption base asset pricing …

Outcomes Of A Participatory Approach To Interpretive Planning In The Shark Bay World Heritage Area, Western Australia, Kelly J. Chapman

Theses: Doctorates and Masters

This thesis examines a participatory approach to interpretive planning, employed in the Shark Bay World Heritage Area, Western Australia. At the project outset relations between the conservation agency responsible for administering World Heritage and the local community were strained, and complicated by a history of conflict over the World Heritage listing and subsequent management of the area. A participatory approach to interpretive planning was adopted in the hope that doing so would achieve the following: improved relations between polarised stakeholder groups, increased community support for the plan and its implementation, and improved access to the variety of knowledge pools within …

Comparative Estimate Of Resistance To Drought For Selected Karstic Aquifers In Bulgaria, Tatiana Orehova

International Journal of Speleology

Effective management of water resources requires adequate knowledge of groundwater system including the influence of climate variability and climate change. The drought of 1982-1994 in Bulgaria has led to important decrease of springflow and lowering of water levels. Therefore, groundwater demonstrated its vulnerability to drought. The purpose of this paper is to determine relative resistance of selected aquifers in Bulgaria to a prolonged decrease of recharge to groundwater. The drought resistance indicator has been defined for some karstic aquifers based on the method proposed in report of BRGM. The data from National Hydrogeological Network located in the National Institute of …

Paleocollapse Structures As Geological Record For Reconstruction Of Past Karst Processes During The Upper Miocene Of Mallorca Island, P. A. Robledo Ardila, J. J. Durán, L. Pomar

International Journal of Speleology

Paleocollapse structures and collapse breccias are one of the major features for paleokarst analysis and paleoclimate record. These are affecting the Llucmajor and Santanyí carbonate platforms. These platforms, of southern and eastern Mallorca respectively, are a good example of progradation reef platform in the western Mediterranean. The Santanyí platform is constituted of two sedimentary units, both affected by paleocollapse structures: (1) The Reef Complex attributed to the upper Tortonian-lower Messinian; (2) Santanyí Limestone attributed to the Messinian. There are abundant paleocollapse outcropping in the Reef Complex and Santanyí Limestone units. These structures have been produced by roof collapse of caverns …

Cave Temperatures And Global Climatic Change, Giovanni Badino

International Journal of Speleology

The physical processes that establish the cave temperature are briefly discussed, showing that cave temperature is generally strictly connected with the external climate. The Global Climatic changes can then influence also the underground climate. It is shown that the mountain thermal inertia causes a delay between the two climates and then a thermal unbalance between the cave and the atmosphere. As a consequence there is a net energy flux from the atmosphere to the mountain, larger than the geothermal one, which is deposited mainly in the epidermal parts of caves.

The Role Of The Environmental Archaeologist In The Study And Reconstruction Of Cave Palaeoclimate, Maria Gkioni

International Journal of Speleology

Man and environment are engaged in a continuous battle to impose themselves on one another. The results are found in environmental modifications or climatic oscillations and, as far as man is concerned, in the different character of cultural remains. Man responds to environmental changes by migrating or evolving technological innovations, both of which leave important remains that the archaeologist is called on to recognise and interpret during and after an excavation. They both also reflect the sociocultural responses to climatic stress. This paper refers to a specific case study, caves, which housed man and his activities from the very early …

A Generic Approach To Supporting The Management Of Computerised Clinical Guidelines And Protocols, Kudakwashe Dube

Doctoral

Clinical guidelines or protocols (CGPs) are statements that are systematically developed for the purpose of guiding the clinician and the patient in making decisions about appropriate healthcare for specific clinical problems. Using CGPs is one of the most effective and proven ways to attaining improved quality, optimised resource utilisation, cost containment and reduced variation in healthcare practice. CGPs exist mainly as paper-based natural language statements, but are increasingly being computerised. Supporting computerised CGPs in a healthcare environment so that they are incorporated into the routine used daily by clinicians is complex and presents major information management challenges. This thesis contends …

An Intervention Model To Improve Overall Learning For Rural At-Risk Kindergartners, Vivian S. Burke

Abraham S. Fischler College of Education ETD Archive

This applied dissertation investigated whether at-risk kindergarten students who were taught with the 5 standards of effective pedagogy over an 8-month period would score higher on achievement measures. The 5 pedagogy standards are (a) joint productive activity, (b) language and literacy development, (c) meaning making, (d) complex thinking, and (e) instructional conversation. These standards emerged from principles of practice that have proven successful with majority and minority at-risk students in a variety of teaching and learning settings over several decades (R. G. Tharpe, 1988).

The researcher developed indicators for each standard, revealing action components of the standards and their functions …

Investigating The Impact Of Differentiating Instruction On Student Learning In Middle School Mathematics Class, Marcia Adams O’Neil

Abraham S. Fischler College of Education ETD Archive

Mathematical achievement across this country lags behind not only that of other industrialized nations but also behind that of other disciplines in the United States as documented by the Third International Math and Science Survey (National Center for Educational Statistics, 1999). Archival data from the state assessment, Massachusetts Comprehensive Assessment System, over the past 4 years document that mathematics performance lags behind English/language arts at all levels. Moreover, performance in mathematics is stagnant at the middle school level, Grades 6-8, unlike continual gains at the elementary and high school level. Clearly, student performance at the middle school level is an …

Symptoms And Possible Causes For Low Enrollment And Participation In The Advanced Placement Program, Debra A. Calvin

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was designed to increase the participation rate of students in the advanced placement (AP) program in a comprehensive high school. The participation rate at this particular site was 8.69% for the 2001-2002 school year. An audit conducted at that time indicated that given the school’s demographics, the AP participation rate should have been at 20%. A strong AP program is advantageous not only to the students actually taking the course but to the entire student body as well. A system was set in place that did not promote the growth and development of AP.

The writer developed …

Investigation Of Spatial Filtering For Planar Range-Resolved Pulsed Laser Ablated Plume Imaging, James F. Winslow

USF Tampa Graduate Theses and Dissertations

This thesis presents a study of the intensified charge-coupled device (ICCD) imaging of pulsed laser ablated plumes. Two-dimensional imaging of laser ablated plumes is a very important diagnostic for PLD. ICCD array photography is a useful tool for imaging PLD. The images obtained using the standard technique are characterized and compared with ICCD images of an altered plume, ICCD images intentionally violating standard imaging procedures, and film thickness. The depth resolving properties of a pinhole was investigated with the intention of applying it to PLD plume imaging. This results in a more thorough understanding of the depth resolving property of …

Compositional And Mineralogical Relationships Between Mafic Inclusions And Host Lavas As Key To Andesite Petrogenesis At Mount Hood Volcano, Oregon, Melinda Michelle Woods

Dissertations and Theses

Throughout its eruptive history, Mount Hood has produced compositionally similar calc-alkaline andesite as lava flows and domes near the summit and basaltic andesitic flows from flank vents. Found within the andesite are slightly more mafic inclusions that are compositionally similar to the host andesite (or host lavas); no inclusions were found in the flank lavas. Host lavas and inclusions have the following mineral assemblage: plag + opx ± cpx ± amp + oxides. Flank lava mineralogy is similar to the inclusions and host lavas, but since they are more mafic they contain olivine instead of amphibole. Average silica content among …

Evaluation Of The Training Program For Beginning Teachers At University School, Tara Ellsley

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was designed to improve the support of beginning teachers at University School of Nova Southeastern University, a private high school. Veteran teachers, administrators, and support staff were not adequately prepared to integrate the beginning teachers who were rapidly leaving for employment elsewhere. There had been no attempt to identify their needs or evaluate their support system. Therefore, school leaders did not have the information necessary to address the retention problem.

The project identified beginning teacher needs and determined if the school was meeting those needs by answering the following questions: (a) What do beginning upper school teachers …
