In Defense Of A Fluctuating-Interface, Particle-Accretion Origin Of Folia, Donald G. Davis

International Journal of Speleology

Two recent papers have proposed radically different modes of origin for cave folia. Audra et al. (2009) propose subaqueous origin of carbonate folia via hypogenic CO₂ bubble trapping, with concurrent condensation-corrosion and evaporative precipitation within individual folia gas pockets. Queen (2009) proposes that at least some folia are analogous to suboceanic tufa-tower "flanges" and may result from subaqueous freshwater mixing into a briny environment. The purpose of this paper is to show that neither of these mechanisms can be the fundamental process responsible for folia morphology in cave deposits, and that accretion from adherent particles at fluctuating interfaces is …

Spatially Dense Drip Hydrological Monitoring And Infiltration Behaviour At The Wellington Caves, South East Australia, Catherine N. Jex, Gregoire Mariethoz, Andy Baker, Peter Graham, Martin S. Andersen, Ian Acworth, Nerilee Edwards, Cecilia Azcurra

International Journal of Speleology

Despite the fact that karst regions are recognised as significant groundwater resources, the nature of groundwater flow paths in the unsaturated zone of such fractured rock is at present poorly understood. Many traditional methods for constraining groundwater flow regimes in karst aquifers are focussed on the faster drainage components and are unable to inform on the smaller fracture or matrix-flow components of the system. Caves however, offer a natural inception point to observe both the long term storage and the preferential movement of water through the unsaturated zone of such fractured carbonate rock by monitoring of drip rates of stalactites, …

Bacterial Community Survey Of Sediments At Naracoorte Caves, Australia, Eric M. Adetutu, Krystal Thorpe, Esmaeil Shahsavari, Steven Bourne, Xiangsheng Cao, Ramin Mazaheri Nezhad Fard, Greg Kirby, Andrew S. Ball

International Journal of Speleology

Bacterial diversity in sediments at UNESCO World Heritage listed Naracoorte Caves was surveyed as part of an investigation carried out in a larger study on assessing microbial diversity in caves. Cave selection was based on tourist accessibility; Stick Tomato and Alexandra Cave (> 15000 annual visits) and Strawhaven Cave was used as control (no tourist access). Microbial analysis showed that Bacillus was the most commonly detected microbial genus by culture dependent and independent survey of tourist accessible and inaccessible areas of show (tourist accessible) and control caves. Sediment bacterial groups were assigned to the Firmicutes, Actinobacteria and Proteobacteria. The survey …

Active Tectonics And Earthquake Destructions In Caves Of Northern And Central Switzerland, Arnfried Becker, Philipp Häuselmann, Jost Eikenberg, Eric Gilli

International Journal of Speleology

The present publication focuses on the study of caves in northern and central Switzerland in order to detect and date historical earthquakes and active tectonic displacements by investigations of broken and resealed or displaced speleothems datable by U/Th and ¹⁴C. While it can be shown that these methods are potentially suitable, the ages obtained are often beyond the range of historically recorded earthquakes, and it cannot be proved that the observed and dated events are related to a seismic event. Particularly this is true for the caves in central Switzerland, where most ages in the Melchsee-Frutt region were beyond …

Corrosion Of Limestone Tablets In Sulfidic Ground-Water: Measurements And Speleogenetic Implications, Sandro Galdenzi

International Journal of Speleology

The measurement of the weight loss in limestone tablets placed in the Grotta del Fiume (Frasassi, Italy) provided data on the rate of limestone dissolution due to the sulfidic water and on the influence of local environmental conditions.

A linear average corrosion rate of 24 mm ka^-1 was measured in stagnant water, while the values were higher (68-119 mm ka^-1) where the hydrologic conditions facilitate water movement and gas exchanges. In these zones the increase in water aggressivity is due to mixing with descending, O₂-rich, seepage water and is also favored by easier gas exchange …

Cryogenic Fracturing Of Calcite Flowstone In Caves: Theoretical Considerations And Field Observations In Kents Cavern, Devon, Uk., Joyce Lundberg, Donald A. Mcfarlane

International Journal of Speleology

Several caves in Devon, England, have been noted for extensive cracking of substantial flowstone floors. Conjectural explanations have included earthquake damage, local shock damage from collapsing cave passages, hydraulic pressure, and cryogenic processes. Here we present a theoretical model to demonstrate that frost-heaving and fracture of flowstone floors that overlie wet sediments is both a feasible and likely consequence of unidirectional air flow or cold-air ponding in caves, and argue that this is the most likely mechanism for flowstone cracking in caves located in Pleistocene periglacial environments outside of tectonically active regions. Modeled parameters for a main passage in Kents …

Diversity And Community Assembly Patterns Of Epigean Vs. Troglobiont Spiders In The Iberian Peninsula, Pedro Cardoso

International Journal of Speleology

Cave-obligate organisms usually have smaller ranges and their assemblages have higher beta diversity than their epigean counterparts. Phylogenetic and functional diversity is usually low in cave communities, leading to taxonomic and functional disharmony, with entire groups missing from the subterranean realm. The objective of this work is to compare range, beta diversity, phylogenetic and functional diversity, taxonomic and functional disharmony of epigean versus troglobiont spiders in the Iberian Peninsula.

The median extent of occurrence was found to be 33 times higher for epigean than for cave species. Beta diversity was significantly higher for troglobiont assemblages. Cave assemblages present lower phylogenetic …

Provenance And Geological Significance Of Red Mud And Other Clastic Sediments Of The Mugnano Cave (Montagnola Senese, Italy), Francesco Iacoviello, Ivan Martini

International Journal of Speleology

The Mugnano cave is characterized by a thick clastic sedimentary fill showing a great variability of sedimentary facies, ranging from clay to coarse-grained sand deposits. This paper deals with combined sedimentological and mineralogical (XRD and SEM) studies of these sediments and bedrock insoluble residues in order to understand the origin and geological significance of cave deposits, with particular attention to red mud sediments, often considered as the residue of host rock dissolution. Three different sedimentary facies were recognized: i) YS, yellow sand with occasionally shell fragments, testifying the arrival of sediments from the surrounding landscape; ii) RS, red laminated mud; …

Federal Neighborhood Stabilization Policy Deployment In Select Florida Jurisdictions, Kevin Carl Mccarthy

USF Tampa Graduate Theses and Dissertations

In 2008 the Federal government enacted a Neighborhood Stabilization Program (NSP) to address the neighborhood effects of the late-2000s foreclosure crisis. Congress subsequently funded a second and third NSP. This research employs mixed methods to examine the effectiveness of the first round of the NSP in three Florida jurisdictions. The results are analyzed within the larger context of substantive housing theory and federal housing policy. The success of the program is evaluated using a mixed-scanning procedural planning theoretical framework.

Examining The Relationship Between Participatory Democracy And Nonwhite Domestic Workers In Porto Alegre, Brazil: Issues Of Race, Class And Privilege, Alexis Nicole Mootoo

USF Tampa Graduate Theses and Dissertations

Brazil is a nation that has professed to be a `racial democracy' such that race categories are not recognized. This implies that every citizen experiences equal access from a political, social and economic point of view, irrespective of skin color. Nevertheless, palpable racial inequalities exist in Brazil such that there is a primarily white elite class while Brazilians of African descent are typically poor. Male dominance is a worldwide phenomenon. When racial inequities are coupled with male dominance, Brazilian women of African origins suffer as they occupy the lowest socio-economic strata, which often remand them to work as domestics. Some …

Out Of The Land Of Forgetfulness: Archaeological Investigations At Bulow Plantation (8fl7), Flagler County, Florida, Rebecca Claire O'Sullivan

USF Tampa Graduate Theses and Dissertations

Developed in the early 1800's, Bulow Plantation is a prime example of the thriving sugar industry of East Florida prior to the Second Seminole War. Additionally, the layout of the slave cabins at Bulow Plantation in an arc centered on the main house is unique in Florida except for Kingsley Plantation near Jacksonville, FL. Despite its importance and the paucity of information available about even basic questions regarding life at Bulow Plantation, relatively little in the way of archaeological work has been done at the site. Using historical research and non-destructive archaeological techniques such as pedestrian survey, aerial LiDAR (Light …

Use Of Adventitious Roots For The Determination Of Hydroperiod In Isolated Wetlands, Michael Joseph Reyes

USF Tampa Graduate Theses and Dissertations

Abstract

Accurate measurement of the hydroperiod in isolated wetlands currently relies upon the installation and frequent monitoring of devices such as piezometers and staff gauges. Observations of biological indicators of the hydroperiod may be able to supplement data collected from these devices and could potentially replace them as a means of accurately determining this hydrologic interval. The study objective was to determine whether adventitious root formation and maturation on buttonbush (Cephalanthus occidentalis) could be used as a viable indicator of the hydroperiod in isolated wetlands. Buttonbush seedlings were flooded in a controlled environment over a three month period in the …

The Effect Of Mortgage Liberalization On Housing Patterns In Tampa Bay, Jason Richardson

USF Tampa Graduate Theses and Dissertations

This study seeks to determine whether the process of mortgage finance liberalization, manifested in concurrent activities of securitization, deregulation, and neo-liberal policy, have resulted in changes to the tenure of residents in neighborhoods in Tampa Bay. It makes use of existing literature on gentrification and mortgage finance and compares those findings with three sample neighborhoods in and around the city of Tampa. To do so the thesis employs data collected from lenders pursuant to the Home Mortgage Disclosure Act, court records of sales and mortgages filed with the Clerk of the Circuit Court of Hillsborough County, and interviews with stakeholders …

Mapping And Assessing Urban Impervious Areas Using Multiple Endmember Spectral Mixture Analysis: A Case Study In The City Of Tampa, Florida, Fenqing Weng

USF Tampa Graduate Theses and Dissertations

The advance in remote sensing technology helps people more easily assess urban growth. In this study, the utility of multiple endmember spectral mixture analysis (MESMA) is examined in a sub-pixel analysis of Landsat Thematic Mapper (TM) imagery to map urban physical components in Tampa, FL. The three physical components of urban land cover (LC): impervious surface, vegetation and soil, were compared using the proposed MESMA with a traditional spectral mixture analysis (SMA). MESMA decomposes each pixel to address the heterogeneity of urban LC characteristic by allowing the number and types of endmembers to vary on a per pixel basis. This …

Resisting Criminalization Through Moses House: An Engaged Ethnography, Lance Arney

USF Tampa Graduate Theses and Dissertations

Neoliberal restructuring of the state has had destructive effects on families and children living in urban poverty, compelling them to adapt to the loss of social welfare and demolition of the public sphere by submitting to new forms of surveillance and disciplining of their individual behavior. A carceral-welfare state apparatus now confines and controls the bodies of expendable laborers in urban spaces, containing their threat to the neoliberal socioeconomic order through criminalization and workfare assistance, resulting in a new symbiosis of prison and ghetto. The resulting structures of punishment, police surveillance, and criminalization primarily surround African Americans living in high …

The Relationship Between The Social Construction Of Race And The Black/White Test Score Gap In, Toriano M. Dempsey

USF Tampa Graduate Theses and Dissertations

ABSTRACT

This research is an investigation into the relationship between the resegregation of American

public schools and the social creation of race. This research is based on the popular notion that

American public schools are failing to produce students capable of competing in today's global society.

The proof most often used to assert the failure of American public schools is the Black/White Test Score

Gap. For the purposes of this research the Black/White Test Score Gap is defined as the gap between

the scores on academic standardized tests between Black public school students and White public school

students regardless of …

Reciprocity And Development In Disaster-Induced Resettlement In Andean Ecuador, Albert J. Faas

USF Tampa Graduate Theses and Dissertations

This dissertation addresses gaps in anthropological knowledge about how reciprocity--and a specifically Andean form of reciprocity--works in disaster and resettlement settings. This study looks at the practices of reciprocity in a disaster-affected community (Manzano) and a disaster-induced resettlement (Pusuca) in the Andean highlands of Ecuador. Specifically, it examines two aspects of reciprocal exchange practices in these sites. It first looks at some of the factors that affect the continuity of reciprocal exchange practices, which other studies have found to play a vital role in recovery from disasters and resettlement. It then looks to the roles of unequal power relations in …

Effects Of Gps Error On Animal Home Range Estimates, Garrett Hyzer

USF Tampa Graduate Theses and Dissertations

This study examined how variables related to habitat cover types can affect the positional accuracy of Global Positioning System (GPS) data and, subsequently, how wildlife home range analysis can be influenced when utilizing this inaccurate data. This study focused on measuring GPS accuracy relative to five habitat variables: open canopy, sparse canopy, dense canopy, open water, and building proximity. The study took place in Hillsborough County, in residential areas that contain all of these habitat types. Five GPS devices, designed for wildlife tracking purposes, were used to collect the data needed for this study. GPS data was collected under the …

This research combines all these data with information obtained from existing artifact …

Wrecking Recreation Center Relationships: How Policy Affects Urban Youth In Tampa, Florida, Brett A. Mervis

USF Tampa Graduate Theses and Dissertations

This dissertation explores the impact of housing and recreation policy on Tampa's urban youth. Deconcentration policy suggests that public housing youth have improved life chances when relocated to mixed-income neighborhoods. In 2007, Tampa's Central Park Village (CPV) public housing complex was demolished and all families were relocated to new neighborhoods. Similarly, neoliberal policy advocates for the government's reduced role in poverty-alleviating mechanisms to include housing the poor and the funding of afterschool programs. To offset a smaller city budget due to state property tax rollbacks in the mid-2000's, Tampa Parks and Recreation instituted increased afterschool and youth sports participation fees. …

Walking In The Land Of Cars: Automobile-Pedestrian Accidents In Hillsborough County, Florida, Marc Aaron Poling

USF Tampa Graduate Theses and Dissertations

Analyses of traffic accidents are often focused on the characteristics of the accident event and hence do not take into account the broader neighborhood contexts in which accidents are located. This thesis seeks to extend empirical analyses of accidents by understanding the link between accidents and their surroundings. The case study for this thesis is Hillsborough County, Florida, within which the city of Tampa is located. The Tampa Bay region ranks very high in terms of accident rates within U.S. metropolitan areas and is also characterized by transport policies which favor private automobiles over mass transit options, making it an …
