Hunter-Gatherer Use Of Small Animal Food Resources: Coprolite Evidence, Karl J. Reinhard, J. R. Ambler, C. R. Szuter

School of Natural Resources: Faculty Publications

Faunal remains are commonly found in coprolites and provide direct evidence of animal consumption. An evaluation of hunter-gatherer coprolites from the Southwest United States shows that animal bone in coprolites can be used to assess patterns of hunting, food preparation, and general importance of small animals in diet. This is demonstrated by a comparison of faunal assemblages between two hunter-gatherer sites with respect to small animal hunting strategies. The sites are Dust Devil Cave on the Colorado Plateau, an Archaic winter habitation, and Hinds Cave, a warm season Archaic habitation in the lower Pecos of Texas. The results indicate that …

Loop Quantization Of Spherically Symmetric Midi-Superspaces, Miguel Campiglia, Rodolfo Gambini, Jorge Pullin

Faculty Publications

We quantize the exterior of spherically symmetric vacuum spacetimes using a midi-superspace reduction within the Ashtekar new variables. Through a partial gauge fixing we eliminate the diffeomorphism constraint and are left with a Hamiltonian constraint that is first class. We complete the quantization in the loop representation. We also use the model to discuss the issues that will arise in more general contexts in the 'uniform discretization' approach to the dynamics. © 2007 IOP Publishing Ltd.

Revisiting He-Like X-Ray Emission-Line Plasma Diagnostics, R. L. Porter, Gary J. Ferland

Physics and Astronomy Faculty Publications

A complete model of helium-like line and continuum emission has been incorporated into the plasma simulation code Cloudy. All elements between He and Zn are treated, any number of levels can be considered, and radiative and collisional processes are included. This includes photoionization from all levels, line transfer, including continuum pumping and destruction by background opacities, scattering, and collisional processes. The model is calculated self-consistently along with the ionization and thermal structure of the surrounding nebula. The result is a complete line and continuum spectrum of the plasma. Here we focus on the ions of the He I sequence and …

The Relationship Between Family Composition And Social Behavior For Students With Mild Disabilities In Schools, Amanda Clark

Theses and Dissertations

Previous research identifies significant differences in children's problem behavior across various family structures, particularly noting more challenging behaviors in children from single parent families. Utilizing a pre-existing data set of Behavioral Objective Sequence (BOS) scores, this study investigated teacher ratings of social behavioral skills in students with mild disabilities, focusing on differences between groups of students from a variety of family compositions. Results indicated no significant difference in social behavioral skills among children from different family groups, taking into account the student's age. The covariate of age was significant on each of six BOS subscales, suggesting that children develop and …

Cost/Effectiveness Analysis Of Obtaining Operational Estimates Of Reference Evapotranspiration, Peninsular Florida, Usa, Michael G. Kittridge

USF Tampa Graduate Theses and Dissertations

The objective of this study is to conduct a cost/effectiveness analysis of the computation of reference evapotranspiration (ETo) in the peninsular of Florida. A meteorological station on the Fort Meade Mine in Polk County, Florida was used to provide data for the calculation of ETo. Five ETo equations were tested to determine the accuracy and cost/effectiveness to the fully measured ASCE Penman-Monteith (Full ASCE-PM) equation on daily, monthly, and annually time steps. The ETo equations ranged in amounts of parameters from the Full ASCE-PM to the Hargreaves. The energy terms accounted for approximately 90% of the total ETo flux. Solar …

Methyl Esterification Of Fatty Acids And Eicosanoids With A Novel Reagent Trimethylsilyldiazomethane For Analysis By Gas Chromatography-Mass Spectrometry, Aditi Munmun Sengupta

Master's Theses and Doctoral Dissertations

Fatty acids are compounds with limited water solubility that belong to the lipid class of bio-organic compounds and can be utilized as a source of energy by the body or as precursors to oxidized compounds that have roles in inflammation and in the regulation of vascular tone. The prostaglandins are naturally occurring 20-carbon cyclopentano fatty acid derivatives produced in mammalian tissue from polyunsaturated fatty acids (PUFAs) and are generated from endoperoxide precursors of arachidonic acid and related polyunsaturated fatty acids by the enzyme cyclo-oxygenase (COX). The lipoxygenase (LOX) enzymes convert arachidonic acid into hydroperoxy derivatives of PUFAs termed leukotrienes, which …

On The Age And Metallicity Estimation Of Spiral Galaxies Using Optical And Near-Infrared Photometry, Hyun Chul Lee, Guy Worthey, Scott C. Trager, S. M. Faber

Physics & Astronomy Faculty Publications

In integrated light, some color-color diagrams that use optical and near-infrared photometry show surprisingly orthogonal grids as age and metallicity are varied, and they are coming into common usage for estimating the average age and metallicity of spiral galaxies. In this paper we reconstruct these composite grids using simple stellar population models from several different groups convolved with some plausible functional forms of star formation histories at fixed metallicity. We find that the youngest populations present (t < 2 Gyr) dominate the light, and because of their presence the age-metallicity degeneracy can be partially broken with broadband colors, unlike older populations. The scatter among simple stellar population models by different authors is, however, large at ages t < 2 Gyr. The dominant uncertainties in stellar population models arise from convective core overshoot assumptions and the treatment of the thermally pulsing asymptotic giant branch phase and helium abundance may play a significant role at higher metallicities. Real spiral galaxies are unlikely to have smooth, exponential star formation histories, and burstiness will cause a partial reversion to the single-burst case, which has even larger model-to-model scatter. Finally, it is emphasized that the current composite stellar population models need some implementation of chemical enrichment histories for the proper analysis of the observational data. © 2007.

Biosedimentology Of Thermal Features In The Uzon Caldera, Kamchatka, Russia : Implications For Biosignature Formation, Jessica Christine Goin

Dissertations and Theses

Modern hot springs serve as a habitat for microorganisms similar in metabolism, morphology, and cellular structure to the microbes that existed relatively early in Earth history. To maximize our ability to interpret evidence for these microorganisms and their communities in the rock record, we need to understand how their biosignatures form and become preserved.

This biosedimentological study of four thermal features in the Uzon Caldera (K4 Well, Ochki Pool, Thermophile Spring, and Zavarzin Pool) focused on identifying how chemical, physical and biological inputs contribute to the characteristics of sinter biofabrics. The biofabrics of K4 Well outflow channel were studied in …

Development Of Informative Priors In Microarray Studies, Kassandra M. Fronczyk

Theses and Dissertations

Microarrays measure the abundance of DNA transcripts for thousands of gene sequences, simultaneously facilitating genomic comparisons across tissue types or disease status. These experiments are used to understand fundamental aspects of growth and development and to explore the underlying genetic causes of many diseases. The data from most microarray studies are found in open-access online databases. Bayesian models are ideal for the analysis of microarray data because of their ability to integrate prior information; however, most current Bayesian analyses use empirical or flat priors. We present a Perl script to build an informative prior by mining online databases for similar …

On Stability And Evolution Of Solutions In General Relativity, Stephen M. Taylor

Theses and Dissertations

This thesis is concerned with several problems in general relativity and low energy string theory that are pertinent to the time evolution of the gravitational field. We present a formulation of the Einstein field equations in terms of variational techniques borrowed from geometric analysis. These equations yield the evolution equations for the Cauchy problems of both general relativity and low energy string theory. We then proceed to investigate the evolutionary linear stability of Schwarzschild-like solutions in higher dimensional relativity called black strings. These objects are determined to be linearly unstable. This motivates a further stability analysis of the charged p-brane …

James E. Talmage And The Nature Of The Godhead: The Gradual Unfolding Of Latter-Day Saint Theology, Brian William Ricks

Theses and Dissertations

Since the beginning of Christianity, the debates over the nature of God have been frequent and ardent. Augustine, John Calvin, and John Wesley, with others, supplemented the generally accepted view of the Godhead as established at the Council of Nicaea in 325 A.D. Correctly understanding the Father, the Son, and the Holy Ghost is one of the most critical aspects of religious worship. The Savior said, "And this is life eternal, that they may come to know thee the only true God, and Jesus Christ, whom thou hast sent" (John 17:3). Joseph Smith, the first Latter-day Saint Prophet, taught a …

Holmes, Alice, And Ezeulu: Western Rationality In The Context Of British Colonialism And Western Modernity, Andrew B. Schultz

Theses and Dissertations

This thesis examines Western rationality, contextualizing that subject in British colonialism and Western modernity. Using Scott Lash's description of academic characterizations of modernity, I explore the “high" modernity of the social sciences represented in the books Alice's Adventures in Wonderland by Lewis Carroll and The Hound of the Baskervilles by Arthur Conan Doyle. I then explore the cultural studies critique of that characterization of modernity in the book Arrow of God by Chinua Achebe. Using the theory of Jean Francois Lyotard, Martin Heidegger, and Theodor Adorno, I look at Western rationality through its manifestation in British colonialism. I argue that …

Demographics Of Black Vultures In North Carolina, Bradley F. Blackwell, Michael L. Avery, Bryan D. Watts, Martin S. Lowney

United States Department of Agriculture Wildlife Services: Staff Publications

Understanding the contributions of vital rates to species population growth is critical to developing new management protocols. We constructed a model population for black vultures (Coragyps atratus) in North Carolina, USA, based on demographic data from a 14-year study. The model population was similar in stage structure to the reference population, and adult survival was the primary contributor to the annual rate of increase (10.6%). We suggest that the North Carolina black vulture population is experiencing high rates of survival and fertility, potentially breeding at an age younger than previously assumed, and growing rapidly.

Loading Rate Effects On Axial Pile Capacity In Clays, Michael Paul Garner

Theses and Dissertations

In order to design more efficient and reliable structures, axial load tests are performed on foundation piles. Traditionally, static tests with an average duration of approximately twenty-four hours have been performed on test piles to obtain their axial capacity. These static tests require multiple piles used as anchors in addition to the test pile. Static tests are both expensive and time consuming. An alternative to static testing is dynamic testing which requires sophisticated interpretation, can damage the pile and may not produce accurate results. There is a relatively new testing method called the Statnamic Testing Method which tests foundation piles …
