Reducing False Alarms In Searches For Gravitational Waves From Coalescing Binary Systems, Andres Rodri­Guez

LSU Master's Theses

LIGO observatories in Livingston, LA and Hanford, WA may detect gravitational waves emitted from coalescing binary systems composed of two compact objects. In order to detect compact binary coalescence (CBC) events, LIGO searches utilize matched filtering techniques. Matched filtering is the optimal detection strategy for stationary, Gaussian noise, however, LIGO noise is often non-stationary, non-Gaussian. Non-stationary noise result in an excess of false candidate events, commonly known as false alarms. This thesis develops the r² test to reduce the false alarm rate for LIGO CBC searches. Results of the search for primordial black hole binary systems (where each object …

Using Least-To-Most Assistive Prompt Hierarchy To Increase Chilld Compliance With Directives In An Inclusive Preschool Classroom, Jamie Lynn Ourso

LSU Master's Theses

Prompt strategies have been used in the literature to increase the compliance of preschool-aged children to teacher directives (Wilder & Atwell, 2006; Wolery & Gast, 1984). The purpose of this study was to train teachers to use guidance/prompt strategies to increase child compliance with teacher directives related to play and social skills. This study builds on the current literature base by using prompting, specifically the least-to-most assistive prompt hierarchy (LtM) (first described by Horner & Keilitz, 1975), with the additional requirement of teacher-child proximity and teacher-child eye level prior to beginning the prompt sequence. These two additional requirements are consistent …

Early Flotant Establishment And Growth Dynamics In A Nutrient Amended Wetland In The Lower Mississippi River Delta, Caleb W. Izdepski

LSU Master's Theses

Nutrient dynamics and seasonal marsh growth were examined in a newly formed Panicum virgatum floating marsh at Thibodaux LA. The floating marsh formed in a cleared area of forested wetland receiving secondarily treated effluent. Net Areal Primary Productivity (NAPP), total belowground biomass, NO₃, and δ¹⁵N ratios varied significantly (P <0.05) along a 75m marsh transect while mean δ¹³C varied between plant species. The upland end of the transect had the highest NAPP (3876 g m^-2y^-1), total belowground biomass (4079.0 ± 298.5 g m^-2), and mean NO₃ (5.4 ± 2.9 mg l^-1). The mean floating-marsh …

Anywhere But Here: Race And Empire In The Mabo Decision, Emma Cunliffe

All Faculty Publications

The High Court of Australia's decision in Mabo v. Queensland (No.2) is among the most widely known and controversial decisions the Court has yet delivered. In Mabo, a majority of the Court recognised a common law right to native title subject to certain criteria. In this article, I explore the competing visions of legal history that are implicit within Brennan J's leading judgment and Dawson J's dissent. In particular, I discuss the ways in which both of these judgments render an incomplete and contradictory documentary record more coherent than it really is. Suggesting that neither judgment manages to escape the …

How To Rewrite Torah: The Case For Proto-Sectarian Ideology In The Reworked Pentateuch (4qrp), Roger S. Nam

Faculty Publications - Portland Seminary

This study challenges the initial categorization of the Reworked Pentateuch (4Q364-4Q367) as another non-sectarian textual witness to the Torah. A close analysis of the manuscripts suggests that certain unaligned readings likely ret1ect some of the sectarian ideas of the community. Other variants evoke both content and ideology of the authoritative "Rewritten Bible" documents, the Temple Scroll and Jubilees. These characteristics imply that 4QRP contains deliberate reworking of biblical material that is in line with sectarian ideology, in contrast to a mere mechanical copying of the text. Though the scroll may not be strictly sectarian, at the very least, it is …

Using "Hybrid" Effectively In Christian Higher Education, Daniel L. Brunner

Faculty Publications - Portland Seminary

Hybrid is just one of a number of terms used for the convergence of face-to-face and online learning, At the University of Central Florida (UCF) they are called mixed mode courses, In the corporate world the most common language used for hybrid is blended learning, Blended learning, says Bob Mosher, is about using multiple learning modalities, which include, but are not limited to, the Web.7 The blended learning term is also being used more frequently within academic circles,8 Because of the inconsistency in how blended learning is employed, though, and because our goal is not to describe learning in general …

Representing The Object Of Controversy: The Case Of The Molecular Clock, Michael Dietrich

Dartmouth Scholarship

Through a case study of the controversies surrounding the molecular clock, this paper examines the role of visual representation in the dynamics of scientific controversies. Representations of the molecular clock themselves became objects of controversy and so were not a means for closure. Instead visual representations of the molecular clock became tools for the further articulation of an ongoing controversy.

The Effects Of Recq, Uvrd, And Recd Mutants Of Deinococcus Radiodurans On Resistance To Dna Damaging Agents, Stephannie Gauthier Ruiz

LSU Master's Theses

The genes encoding the putative nuclease RecD and the helicase RecQ were deleted from Deinococcus radiodurans R1 and replaced with constructs conferring hygromycin or spectinomycin resistance. The ÄrecD and ÄrecQ strains were found to be similar to wild type R1 strain in resistance to gamma irradiation. In contrast to the single mutant strains, the ÄuvrD, ÄrecQ double mutant was found to be extremely radiation sensitive, indicating that these proteins share a complementary activity needed for radioresistance. ÄrecD mutants have higher transformation efficiencies than the wild type R1 strains, suggesting an association of RecD with nucleases that degrade single stranded DNA. …

Political Institutions, Judicial Review, And Private Property: A Comparative Institutional Analysis, Daniel H. Cole

Articles by Maurer Faculty

Since Madison, jurists of all ideological stripes have more or less casually presumed that constitutional judicial review is absolutely necessary to protect private property rights against over-regulation by political bodies. During the twentieth century, this presumption led directly to the institution of regulatory takings doctrine.

Recently, the economist William Fischel and the legal scholar Neil Komesar have raised important questions about, respectively, the utility and the sufficiency of constitutional judicial review for protecting private property. This article supports their arguments with theoretical and historical evidence that constitutional judicial review (1) is not strictly necessary for protecting private property rights, and …

Direct White Sugar Production: Optimization And Chemical Regeneration Of Fixed-Bed Activated Carbon Adsorbers, Raul Alejandro Cortes

LSU Master's Theses

A system for the direct production of white sugar from clarified sugar cane juice in a raw sugar factory has been developed at the Audubon Sugar Institute. This Direct White Sugar Production (DWiSP) system employs a series of columns packed with adsorbent media. Activated carbon is used in the first column(s) as a filter and bulk decolorizer. Ion exchange resins are then used to remove ash and remaining color. Batch testing was performed in order to determine equilibrium parameters. An analytical model was utilized in conjunction with column loading tests to determine dynamic characteristics of the carbon adsorber for use …

Expectation In Visual Symbolic Processing Of Environmental Symbols In People With Fluent Aphasia, Amanda Stead

LSU Master's Theses

The purpose of this study was to examine aspects of visual symbolic processing in those individuals with fluent aphasia, and how it compares to that of their lexical ability. Two groups of participants were examined: a group with fluent aphasia, and a group of non-neurologically damaged controls. Participants were administered four computer based expectation tasks, two of which were symbolic, and two which were lexical. Each task contained a simple and a complex level. Participants were required to determine if the final stimulus, within a set of four, was congruent or incongruent. The measures taken included both reaction time and …

Protocol Development For Pro-Active Emergency Responses By Veterinary Clinics And Hospitals, Laura Marie Basirico

LSU Master's Theses

The Gulf Coast hurricanes of 2005 necessitated the development of a guidance document concerning emergency preparedness and response for veterinary clinics and hospitals. The aftermaths of the largest natural disasters in United States' history, namely Hurricanes Katrina and Rita, brought to light the need for a protocol designed specifically for veterinarians and veterinary practitioners. Disaster management information was synthesized and modified to be subject-specific for the veterinary community. This synthesis resulted in the creation of the Veterinary Emergency Preparedness and Response (VEPR) manual and website. Two types of data were collected to develop the emergency protocol; interviews with veterinarians and …

Assessment And Analysis Of Quikscat And Coamps Model Vector Wind Products For The Gulf Of Mexico: A Long-Term And Hurricane Perspective, Neha Sharma

LSU Master's Theses

Global weather changes have become a matter of grave concern in hurricane prone areas as intensities of hurricanes are observed to be increasing every year, necessitating improved monitoring capabilities. NASA’s QuikSCAT satellite sensor has provided significant support in analyzing and forecasting winds for the past 8 years. In this study, the performance of QuikSCAT products, including JPL’s latest L2B 12.5km swath winds, was evaluated against buoy-measured winds in the Gulf of Mexico. The long-term study period was 1/2005 – 2/2007. The Coupled Ocean/Atmospheric Mesoscale Prediction System (COAMPS) was also assessed. The regression analyses showed very good results for QuikSCAT products, …

An Investigation Into Japan's Population: The Current State Of Decline, Joel Stewart

Geography Masters Research Papers

Japan is facing a demographic crisis. The population is aging and shrinking at a considerable pace despite the government's efforts to curtail the problem. This rapid change in the demographic structure of Japan is bound to have stark implications on the society and economy of Japan. The objective of this paper is to understand the issues that allowed this impeding crisis to come about. A thorough examination of the current literature on Japan's fertility and population issues revealed that a number of various factors are causing the impending crisis. Some of the factors determined to be affecting the population dilemma …

Implied World Views In Pictures: Reflections From A Cognitive Psychological And Anthropological Point Of View, Michael Ranta

Contemporary Aesthetics (Journal Archive)

In traditional art history, iconological attempts to analyze visual works of art by treating their formal and semantic features as symptoms of more general, implied world views or cultures have occurred rather frequently. Still, such attempts have been criticized for permitting subjective and non-verifiable interpretations. In this paper, however, I will argue that (i) pictorial works of art indeed imply wider world views or schemata, and (ii) that our comprehension of these schemata can be explained by taking into account recent research within cognitive psychology. More specifically, I will argue that intelligence partly consists of the storage and retrieval of …

Nietzsche's Debt To Kant's Theory Of The Beautiful In 'Birth Of Tragedy', R. Kevin Hill

Philosophy Faculty Publications and Presentations

Nietzsche describes Birth of Tragedy as a contribution to “the science of aesthetics”. In this paper, I will argue that a crucial influence on his emerging views was Kant’s Critique of Judgment. Nietzsche’s early aesthetic views are often attributed to some combination of Schopenhauer’s analyses of the plastic arts (inspiring Nietzsche’s conception of the Apollinian) and his analysis of music (inspiring Nietzsche’s conception of the Dionysian) along with Nietzsche’s own original insights into how these combine to form the tragic. As we shall see, the resources of Schopenhauer’s aesthetics were unavailable to Nietzsche due to epistemological commitments he had …

A Surviving Legacy: Nonviolent Resistance In The Congresssional Black Caucus 2001-2007, Rhone Sebastian Fraser

USF Tampa Graduate Theses and Dissertations

Select members of the Congressional Black Caucus through their votes, speeches, arrests and nonviolent forms of protest practice a renewed kind of nonviolent resistance against a neoconservative political agenda advanced by the executive branch of the U.S. government in the past six years. Their practices are nonviolent according to the definition of nonviolence discussed by Martin Luther King, Jr. in his 1962 New York Times Magazine article: "we will take direct action against injustice without waiting for other agencies to act...We will try to persuade with our words---but if our words fail we will try to persuade with our acts." …

School Psychologists’ Provision Of School-Based Mental Health Interventions: A Qualitative Study Of Perceived Barriers, Allison A. Friedrich

USF Tampa Graduate Theses and Dissertations

The primary purpose of this study was to elucidate factors that school psychologists perceive inhibit them from providing more mental health interventions within their professional roles. School psychologists' dual training in mental health and education renders them the logical choice to provide tier II and tier III interventions in schools (National Association of School Psychologists [NASP], 2003). School psychologists appear to be in agreement, as they indicate a desire to spend more time in the provision of roles such as counseling and consultation (e.g., Prout, Alexander, Fletcher, Memis, & Miller, 1993). However, school psychologists currently spend relatively little time in …

Application And Modeling Of Tio2-Supported Gold Nanoparticles For The Preferential Oxidation Of Carbon Monoxide In Excess Hydrogen, Benjamin Alan Grayson

USF Tampa Graduate Theses and Dissertations

This work begins with a brief overview of heterogeneous, characterization techniques, and current hypotheses about gold mechanisms. This is followed by the initial characterization of custom two-phase-method gold nanoparticles provided by the Interfacial Phenomena and Polymeric Materials research group at USF, the anatase TiO2 support and reference Au/TiO2 catalyst provided by the World Gold Council. In order to verify the ability of the two-phase-method GNP catalyst provided to oxidize CO in excess hydrogen, it was necessary to develop an effluent testing protocol. The first experiments involved 24 hour runs to observe catalyst deactivation. Concerns over cycling effects observed in the …

Psychological Consequences Of Child Sexual Abuse And The Risk And Protective Factors Influencing These Consequences, Kelli-Lee Harford

USF Tampa Graduate Theses and Dissertations

Although a number of negative consequences of childhood sexual abuse (CSA) have been identified, research has shown that some survivors of CSA are fairly resilient and do not demonstrate these negative outcomes. The current study examined differences between sexually abused and non-abused children on a number of emotional and behavioral dimensions and on achievement. In addition, the role of factors such as intelligence, abuse severity, gender, history of previous psychological interventions and number of foster homes on outcomes in a group of 117 children between the ages of 7 and 16 with sexual abuse histories and 80 controls who did …

Development Of A Method To Determine Vapor Pressure Data Of Low Volatile Chemicals From A Knudsen Effusion Technique, Andrew R. Harshman

USF Tampa Graduate Theses and Dissertations

Vapor pressure data are vital to understanding impacts that substances, specifically pesticides, may exert on the environment. They enter into atmospheric deposition models for such chemicals which determine the fate and transport of these species in the environment. At normal application temperatures (i.e. room temperature) the vapor pressures of many of these chemicals are too low to be determined by conventional means. An isothermal Knudsen effusion technique was designed and developed in our laboratory for such measurements. The effusion mass as a function of time is measured in our technique using a thickness shear mode (TSM) acoustic wave sensor, which …

Exploring Childcare Professionals' Pedagogical Choice When Guiding Children's Social And Behavioral Development, Mary E. Harper

USF Tampa Graduate Theses and Dissertations

To date the research in the area of social emotional competence has focused on child-based intervention and outcomes. The findings cite effective approaches to assisting children in the area of social and emotional development involving promotion of appropriate social skills, explicit instruction of behavioral expectations, and support for emotional literacy and awareness (Wester --

Stratton, 1990; Hyson, 2004; Fox et al, 2003; Denham & Burton, 1996). These recommended practices requires teacher knowledge and skill, content knowledge in the area of social emotional developmental, and skills in using pedagogical techniques that support acquisition of the aforementioned areas. Educational researchers and specialists …

Marriage, Sin And The Community In The Register Of John Chandler, Dean Of Salisbury 1404-17, Byron J. Hartsfield

USF Tampa Graduate Theses and Dissertations

Marriage is a subject of great interest to the social historian. However, the marriage of the average medieval English villager is very poorly documented, as it bears little obvious relationship to the great affairs of state. Searching for information on such difficult subjects, many social historians have recently turned to legal records, learning to sift them for the intimate details of daily life. The Register of John Chandler, Dean of Salisbury 1404-17 preserves a rich variety of cases presented to the church courts of early fifteenth-century Salisbury. The questmen, selected from the most respectable men of each village, presented to …

Examining The Evolution Of Phosphagen Kinases: A Study Of A Dimeric Arginine Kinase From Sea Urchin (Strongylocentrotus Purpuratus) Eggs, Brenda Christine Held

USF Tampa Graduate Theses and Dissertations

The phosphagen kinases are a family of enzymes that catalyze the reversible phosphorylation of specific phosphagens using ATP as the phosphate donor. The evolutionary relationships between the enzymes in this family have been studied for over 30 years and yet aspects of the relationships remain unclear. Here, arginine kinase from Strongylocentrotus purpuratus eggs was purified to homogeneity and analyzed for physical and kinetic characteristics as well as its sequence homology with other phosphagen kinases. The results indicate that dimeric arginine kinase from S. purpuratus eggs evolved from a dimeric creatine kinase after dimeric creatine kinase evolved from a monomeric arginine …

USF Tampa Graduate Theses and Dissertations

The primary purpose of this study was to determine the effectiveness of implementing desktop 3-dimensional (3D) stereo images of human anatomy into an undergraduate human anatomy distance laboratory. User perceptions of 2D and 3D images were gathered via questionnaire in order to determine ease of use and level of satisfaction associated with the 3D software in the online learning environment. Mayer's (2001, p. 184) principles of design were used to develop the study materials that consisted of PowerPoint presentations and AVI files accessed via Blackboard. The research design employed a mixed-methods approach. Volunteers each were administered a demographic survey and …

The Impact Of Reward Power On Creativity: Does It Depend On The Nature Of The Reward?, Edward Rickamer Hoover

USF Tampa Graduate Theses and Dissertations

This experiment investigated the influence of reward property and reward power on creative performance. It was hypothesized that the magnitude of reward power would moderate the relationship between reward property and creativity. Fifty undergraduate students (45 females, 5 males, X age = 20.72 years, SD age = 4 years) participated. The experimental design was reward power ($0.00, $0.50, or $2.00 per trial) x reward property (informational vs. controlling undertones in the script) x trials (5). Results demonstrated a positive correlation between intrinsic motivation and creative performance (r = .411, p = .03, n = 50). Hypotheses concerning the moderating influence …

High-Stakes Testing In Florida: Media Portrayals And Parental Realities, Jennifer Gilroy Hunsecker

USF Tampa Graduate Theses and Dissertations

In 1998, Florida implemented a system of standardized testing known as the Florida Comprehensive Assessment Test (FCAT). While initially designed as one among many tools to assess student and school progress, the FCAT has become a high-stakes test. Schools whose students fail to meet certain benchmarks are in danger of losing their students to "school choice plans" (which enable parents of children attending failing schools to choose another, more highly rated school) while parents must contend with ever broadening educational policies. The implications of this policy have been far reaching. Textbook makers now market individualized textbooks that teach FCAT content, …
