Reinventing The Colonial Fantasy In The Post-Wwii Era: Jovita Epp's Amado Mio, Ivana R. Klammer

Theses and Dissertations

Austrian playwright Jovita Epp's German language novel Amado mí­o, which takes place in post-WWII Argentina, is a modern adaptation of the traditional colonial novel. As such, the romances between the female main character, an Argentine of German descent, and her two love interests, an Argentine of Spanish descent (Criollo), and an Austrian Argentine, reflect the hopes and fears of persons and/or cultures caught up in the imperialist dreams of their nation. In the wake of WWII, Argentina becomes a space in which European(-descended) settlers can look back at Europe's "barbarism," questioning the imperialist worldviews that brought Europe …

The Dirt On The Ancient Maya: Soil Chemical Investigations Of Ancient Maya Marketplaces, Daniel Aaron Bair

Theses and Dissertations

Various criteria or lines of evidence have been used to identify ancient Maya marketplaces, including location near trade routes, artifactual evidence of trade, open space adjacent to transportation routes, proximity to public structures, low platforms and rock alignments to denote market spaces, and regular patterns in soil and floor chemical concentrations. Seibal and Mayapán were important economic Maya polities controlling the trade routes at the apex of their civilizations. The objectives of these studies were to apply geochemical and geospatial analyses of the soils and floors from public plazas and household patios, to discover the anthropogenic chemical residues of phosphorus …

Empirical Study Of Information Design: Four Experiments, Noel Teresa Alton

Theses and Dissertations

Current design theory sets out many rules and guidelines for designers, but good design is still difficult to replicate. Often the design principles found in the manuals are misapplied, resulting in designs that (1) do not fulfill their purpose and (2) disrupt the clarity of information. This thesis will review and provide experimental data supporting a model of visual form/visual purpose connections based on the semiotic of C.S. Peirce. This model was first used by Amare and Manning (2005, 2006, 2007, 2008, 2009) to evaluate and explain both effective and ineffective visual information design. This thesis will extend their approach, …

Multidisciplinary Assessment And Documentation Of Past And Present Human Impacts On The Neotropical Forests Of Petén, Guatemala, Christopher Stephen Balzotti

Theses and Dissertations

Tropical forests provide important habitat for a tremendous diversity of plant and animal species. However, limitations in measuring and monitoring the structure and function of tropical forests has caused these systems to remain poorly understood. Remote-sensing technology has provided a powerful tool for quantification of structural patterns and associating these with resource use. Satellite and aerial platforms can be used to collect remotely sensed images of tropical forests that can be applied to ecological research and management. Chapter 1 of this article highlights the resources available for tropical forest remote sensing and presents a case-study that demonstrates its application to …

“Some Marvelous Thing”: Leonardo, Caterina, And The Madonna Of The Rocks, Michael Thomas Jahosky

USF Tampa Graduate Theses and Dissertations

Leonardo's Virgin of the Rocks (or Madonna of the Rocks, c.1486) is a masterpiece. Scholars have been unclear, however, about the unconventional cave setting and where Leonardo's inspiration came from. The Song of Songs mentions a beautiful bride being invited to come "into the wall of rocks," and the apocryphal Gospel of James (written around 150 A.D.) tells the story of Jesus being born in a cave outside of Bethlehem. But Leonardo's own personal cave experience in 1481 spurred his desire to find literature that placed Jesus' birth in a cave, or a "wall of rocks." This …

Characterization Of Unidentified Viruses From Florida, Jessie L. Dyer

USF Tampa Graduate Theses and Dissertations

Public Health and clinical laboratories occasionally obtain viral isolates that cannot be typed by routine methods. Therefore, the sequence-independent, single primer amplification (SISPA) technique was adapted to rapidly identify and characterize viral isolates of unknown etiology. A panel of known (West Nile virus and St. Louis encephalitis virus) and unknown viral isolates (environmental samples collected in Florida) were used to develop and refine the SISPA technique. Selectivity for viral genomic sequences was obtained through enriching viral particles by centrifugation, removal of cellular debris by filtration and removal of host genomic material by benzonase application. The SISPA method successfully amplified the …

De Anima, Dna: A Modified Stump/Aquinas Hylomorphic Model, The Soul And The Identity Of Human Persons, Resurrected, Matthew Grant Mcdaniel

Masters Theses

In contemporary metaphysics, there are two popular options for personal numerical identity (NID) over time: substance dualism and materialism. According to recent arguments by some Christian philosophers, both options conflict with the Christian doctrine of the bodily resurrection. Substance dualism trivializes the physical body for NID (when it has some kind of role in the bodily resurrection), and also is seen to conflict with modern neuroscience. But NID and mind cannot be continued solely by the material body, as versions of the Replacement Argument (from Richard Swinburne and Alvin Plantinga) show. There are good aspects to both options, especially with …

Distribution And Trophic Ecology Of Bathylagus Euryops (Teleostei: Microstomatidae) Along The Northern Mid-Atlantic Ridge, Christopher J. Sweetman, Tracey Sutton

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The assemblage structure and ecology of meso- and bathypelagic fishes are poorly known in general, particularly over mid-ocean ridges. In June 2004, the month-long MAR-ECO (Census of Marine Life) research expedition aboard the R/V G.O. Sars sampled the deep-pelagic fauna over the northern Mid-Atlantic Ridge with the objective of quantitatively assessing the nekton associated with the ridge from Iceland to the Azores. A total of 115 discrete-depth trawl samples were taken from the surface to depths of 3000+ meters using two different double-warp midwater trawls, one of commercial fishing size (a large ‘Akra' trawl) and one of oceanographic research size …

Acute Responses To Estradiol Replacement In The Olfactory System Of Apoe-Deficient And Wild-Type Mice, Britto P. Nathan, Michael Tonsor, Robert G. Struble

Faculty Research & Creative Activity

Epidemiological studies suggest that estrogen therapy protects against clinical expression of chronic neurological diseases. These beneficial effects of estrogen therapy are highly modified by apolipoprotein E (apoE) through an unknown mechanism. We examined the short-term effects of estradiol replacement in ovariectomized mice on apoE expression and markers for cell proliferation, reactive gliosis, neuronal maturation, and synaptogenesis in the primary olfactory pathway of wild-type (WT) and apoE knockout (KO) mice. Three days of estradiol replacement increased apoE expression in the olfactory nerve and in the glomerular layer. Estradiol treatment also increased cell proliferation, total cell numbers, number of mature neurons in …

Educating For The Knowledge Age: A Collective Case Study Of Teachers’ Beliefs In A Problem Based Learning Environment, Amy Marie Ruffus Doerr

Dissertations

There is a growing trend in the business literature; education is not preparing students for the Knowledge Age. The literature further states the foundation of a successful Knowledge Economy and the production of its knowledge workers is education. Considering that the school system is a foundation for learning, it is a startling revelation that education reform has not focused more explicitly on knowledge work. If we expect to be successful in the Knowledge Age, a new conception of knowledge and learning is necessary, and will aid in the development of new knowledge workers. This further necessitates a more in depth …

A Taxonomy And Framework For Designing Educational Games To Promote Problem Solving, Richard Van Eck, Woei Hung

Teaching, Leadership & Professional Practice Faculty Publications

Problem solving is often discussed as one of the benefits of games and game-based learning, yet little empirical research exists to support this assertion. It will be critical to establish and validate models of problem solving in games, but this will be difficult if not impossible without a better understanding of problem solving than currently exists in the field of serious games. Problem solving and problem-based learning (PBL) have been studied intensely in both Europe and the United States for more than 75 years. Any models and research on the relation of games and problem solving must build on the …

Daily And Seasonal Patterns Of Activity At Pygmy Rabbit Burrows In Utah, Janet E. Lee, Randy T. Larsen, Jerran T. Flinders, Dennis L. Eggett

Western North American Naturalist

The pygmy rabbit (Brachylagus idahoensis) is a secretive, obligate sagebrush-steppe resident of the Intermountain West and is one of two rabbits in North America that digs its own burrows. Although the pygmy rabbit has a recorded home range of 0.21–67.9 ha in relatively high sagebrush cover (21%–36%), they spend much of their time within 30–100 m of a burrow system. Due to big sagebrush cover in preferred habitat and the secretive behavior of pygmy rabbits, it is often difficult to study this leporid through direct observation. We used remote cameras to document pygmy rabbit activity at burrow systems …

Mineral Lick Use By Gps Radio-Collared Mountain Goats In Southeastern British Columbia, Kim G. Poole, Karl D. Bachmann, Irene E. Teske

Western North American Naturalist

In most populations of mountain goats (Oreamnos americanus), mineral lick use is an essential part of the ecology of the species. In many areas, the distribution and use of licks in the landscape is poorly known, rendering planning for resource development difficult. We examined lick use by 28 GPS radio-collared mountain goats in 2 study areas in southeastern British Columbia during 2004–2005. Viewing collar-location movements on digital orthophotos, we assumed goat use of 6 previously known and 10 suspected mineral licks. Field visits verified that 9 of the 10 suspected sites were mineral licks. Thirteen of the 15 …

Comparison Of Adoptive Vs. Biological Mother-Infant Relationships In Nonhuman Primates, Rachel Ann Bogh

Theses and Dissertations

Studies suggest that adoptees are at risk for a number of psychopathological behaviors. To understand the etiology of this risk, 150 socially housed rhesus macaques were studied, including 107 infants reared with their biological mothers and 43 infants reared with unrelated adoptive mothers. Mother-infant behaviors were recorded across the first 6 months of life. Analyses were performed using a hierarchical linear mixed model. All reported results were tested at p<0.05. Adopted infants were observed on average to approach and leave their mothers more frequently, explore the environment and locomote longer, exhibit more anxiety-like behavior, spend less time being held to their mother's breast, and were rejected by their mothers more when compared to nonadopted infants, indicating they are more likely responsible for maintaining the relationship. They also direct and receive more noncontact aggression on average to other social group members, and showed evidence of higher anxiety exhibiting high levels of anxiety-like self-directed behavior when compared to nonadopted infants. Also, results indicate that adopted infants have significantly lower levels of the CSF serotonin metabolites 5-hydroxyindoleacetic acid when compared to nonadopted infants.

Investigation Of Potential Trapping Bias In Malaise Traps Due To Mesh Gauge, In Two Habitats, David Jensen Betts

Theses and Dissertations

Malaise traps are a common tool for collecting insects used by many researchers. Although there have been variations in the models and materials used for Malaise traps, the potential for sampling bias due to mesh gague has been explored inadequately. This study compared coarse and fine mesh Townes model Malaise traps in two habitats on the Grand Staircase-Escalante National Monument. The two habitats next to the Lick Wash trailhead were defined by dominant vegetation type – sagebrush and grasses or Piñon-Juniper. We collected from three sites per habitat type, over three consecutive days in June in both 2006 and 2007. …

Synthesis Of Glycolipids And Evaluation Of Their Nkt Cell Stimulatory Properties, Yang Liu

Theses and Dissertations

Natural killer T (NKT) cells are a subset of T cells that modify a variety of immune responses. NKT cells recognize glycolipid antigen presented by a molecule called CD1d, a nonclassical antigen-presenting molecule. The best known subset of CD1d-dependent NKT cells expresses an invariant T cell receptor Vα (TCR-α) chain. These are referred to as type I or invariant NKT (iNKT) cells. When stimulated by a glycolipid, NKT cells rapidly release large amounts of cytokines. Cytokines released by NKT cells can induce either Th1 or Th2 responses. Th1 cytokines are effective in regulating bacterial, parasitic, and viral infections. But Th1 …

State Regulation Of Assisted Reproductive Technology, Jonathan J. Morgan

Theses and Dissertations

State regulation of assisted reproductive technology (ART) has been occurring since the inception of earlier technological advances such as artificial insemination to aid human reproduction. I provide a brief overview of the current regulation of ART in the U.S. and the literature on state regulation. Unlike previous studies of ART regulation which use content analysis or case studies of individual state laws I estimate ART regulation for the entire U.S. by using a series of random effects logistic regression models for the time period 1995-2006. To my knowledge this is the first quantitative analysis of ART regulation. I test the …

Foreword:

What is Teratology?

“What a piece of work is an embryo!” as Hamlet might have said. “In form and moving how express and admirable! In complexity how infinite!” It starts as a single cell, which by repeated divisions gives rise to many genetically identical cells. These cells receive signals from their surroundings and from one another as to where they are in this ball of cells —front or back, right or left, headwards or tailwards, and what they are destined to become. Each cell commits itself to being one of many types; the cells migrate, combine into tissues, or …

Developmental Contributions To Variation In Aspen Clones And The Influence Of Pre-Fire Succession Status On Aspen Regeneration Success, Eric A. Smith

Theses and Dissertations

This thesis includes two studies: The first examined developmental changes that take place in the physiology of aspen (Populus tremuloides Michx.) and to characterize developmental influences on patterns of phenotypic trait variation among different aged ramets within the aspen clones. We surveyed eight clones, each with 8 distinct age classes ranging from 1 to 170 yrs in age. Using regression analysis we examined the relationships between ramet age and expression of functional phenotypes. Eight of the phenotypic traits demonstrated a non-linear relationship in which large changes in phenotype occurred in the early stages of ramet development and stabilized thereafter. …

Factors Influencing The Frequency Of Nest Parasitism By Brown-Headed Cowbirds In The Northern Sierra Nevada, Kathi L. Borgmann, Michael L. Morrison

Western North American Naturalist

Nest parasitism by Brown-headed Cowbirds (Molothrus ater) can negatively affect host populations. Landscape-scale factors, such as proximity to residential areas, equestrian riding stables, and grazing allotments, can affect the risk of nest parasitism as well as the abundance of Brown-headed Cowbirds. Recent increases in residential and recreational development along with a reduction in grazing allotments in the northern Sierra Nevada provide an opportunity to reevaluate factors that influence frequency of nest parasitism by Brown-headed Cowbirds. Frequency of nest parasitism increased as the distance to the nearest residential center and distance to the nearest equestrian riding stable decreased. Similarly, …

Pollen Evidence Of Historical Forest Disturbance On The Wasatch Plateau, Utah, Jesse L. Morris, Andrea R. Brunelle, A. Steven Munson

Western North American Naturalist

Environmental indicators from lake sediments provide excellent opportunities to improve understanding of forest disturbance processes and corresponding changes in forest composition. Our research provides a methodology for assessing recent, historic, and prehistoric disturbances using lacustrine sediment records. We collected sediment cores from Blue Lake, a small subalpine lake on the Wasatch Plateau in central Utah. These cores record environmental changes caused by both spruce beetle (Dendroctonus rufipennis Kirby) and human (logging and livestock grazing) modification. We observed deteriorated insect remains in the lake sediments. These remains correspond temporally with a historic spruce beetle outbreak, though alkaline conditions in the …

Efficacy Of Using Passive Integrated Transponder Technology To Track Individual Shorthead Sculpins, Donald W. Zaroban, Steven M. Anglea

Western North American Naturalist

We evaluated the feasibility of using passive integrated transponder (PIT) tags to mark and track individual shorthead sculpins (Cottus confusus). We implanted PIT tags in 80 shorthead sculpins in 2 size categories (60–80 mm and 81–106 mm total length) and in 1 of 2 locations (subcutaneous along the spinous dorsal fin or in the body cavity). We evaluated tag retention, sculpin survival, and net-avoidance behavior for 29 days. We observed no mortality directly attributable to PIT-tag injection at either tagging location. We observed a 38.8% loss rate of dorsal tags and a 2.5% loss rate of body-cavity tags. …

Evaluation Of Brood Detection Techniques: Recommendations For Estimating Greater Sage-Grouse Productivity, David K. Dahlgren, Terry A. Messmer, Eric T. Thacker, Michael R. Guttery

Western North American Naturalist

Obtaining timely and accurate assessment of sage-grouse (Centrocercus spp.) chick survival and recruitment is an important component of species management and conservation. We compared the effectiveness of walking, spotlight, and pointing-dog surveys to detect radio-marked and unmarked chicks within broods of radio-marked hens in Utah. Walking surveys detected 72% of marked chicks, while spotlight and pointing-dog surveys detected 100% and 96%, respectively. We found no difference between spotlight and pointing-dog counts in number of marked and unmarked chicks detected (P = 0.57). Spotlight counts were slightly more time efficient than pointing-dog surveys. However, spotlight surveys were nocturnal searches …

Observations Of Reproduction In Mountain Lions From Nebraska, Sam Wilson, Justin D. Hoffman, Hugh H. Genoways

Western North American Naturalist

Occurrences of mountain lions (Puma concolor) in Nebraska have been steadily increasing; however, reproductive activity in mountain lions has not been documented in the state. We present the first evidence of mountain lion reproduction in Nebraska since mountain lions recolonized the state in the early 1990s. On 28 February 2007, a spotted kitten was hit by a vehicle in northwestern Nebraska; and based on body length and weight, we estimate its age at 3.9 months. On 20 December 2008, a female mountain lion and spotted kitten were photographed in the northwestern part of the state. On 9 May …

Climbing As An Escape Behavior In The American Hog-Nosed Skunk, Conepatus Leuconotus, Wesley B. Brashear, Robert C. Dowler, Gerardo Ceballos

Western North American Naturalist

Climbing behavior is poorly documented in skunk species, with the exception of the genus Spilogale. Herein we describe 2 cases of climbing behavior in the American hog-nosed skunk (Conepatus leuconotus): one in Colima, Mexico, and another in west central Texas, USA. In both cases, a male climbed over 5 m into oak trees when pursued by humans. Climbing as an escape behavior in hog-nosed skunks has not previously been reported.

Nighttime Aboveground Movements By Prairie Dogs On Colonies Inhabited By Black-Footed Ferrets, David A. Eads, Jennifer G. Chipault, Dean E. Biggins, Travis M. Livieri, Joshua J. Millspaugh

Western North American Naturalist

We describe observations of black-tailed prairie dogs (Cynomys ludovicianus) emerging aboveground at night, apparently in response to wild-born and captive-born black-footed ferrets (Mustela nigripes) in South Dakota and New Mexico, respectively. We also discuss other similar observations accumulated on black-tailed prairie dog colonies as well as observations of white-tailed prairie dogs (Cynomys leucurus) making nighttime movements, apparently in response to pre-reintroduction ferrets in Wyoming. Our observations suggest that, in addition to documented daytime defenses against ferrets, prairie dogs reduce vulnerability to predation by ferrets by using evasive movements at night.
