Biofacies Analysis Of Late Mississippian Ostracodes And Their Use As Paleoenvironmental Indicators In The Bluefield Formation, Mercer County, West Virginia, Benjamin T. Stencil Aug 2012

Biofacies Analysis Of Late Mississippian Ostracodes And Their Use As Paleoenvironmental Indicators In The Bluefield Formation, Mercer County, West Virginia, Benjamin T. Stencil

Theses and Dissertations

The Bluefield Formation (Chesterian, Upper Mississippian) of the Appalachian Basin is a lithologically variable unit, composed of mudstones lithofacies with subordinate amounts of sandstone and limestone. By analyzing sedimentology and the prominence of ostracodes, an ostracode biofacies model was generated that provides a large-scale paleoenvironmental framework for the Bluefield Formation. Three ostracode assemblages were defined in an effort to identify environmental conditions during deposition of the Bluefield: Assemblage I - Polytylites Assemblage; Assemblage II - Sansabella Assemblage; and Assemblage III - Whipplella Assemblage. The assemblage distributions indicate that nearshore transitional marine environments were common and normal open marine conditions were …

Insights Into The Taxonomy And Evolution Within An Orchid, Platanthera Dilatata, Based On Orphometrics And Molecular Markers, Binaya Adhikari Aug 2012

Insights Into The Taxonomy And Evolution Within An Orchid, Platanthera Dilatata, Based On Orphometrics And Molecular Markers, Binaya Adhikari

Theses and Dissertations

Documenting biodiversity, at and below the species level, is a persistently challenging task for biologists. Poor understanding of biodiversity may lead to incorrect interpretations of observed variation. The underlying basis of variation can be understood by quantifying multiple sources of information. Nine morphometric characters and plastid DNA sequences (2511 bps) were quantified in a highly variable orchid species, Platanthera dilatata, to evaluate taxonomy of the three named varieties and to understand patterns of evolution. Three morphological groups, identified in a cluster analysis, were distinct in multiple floral traits. Additionally, the three clusters were consistently genetically divergent as indicated by infrequent …

Present And Potential Future Distribution Of Common Vampire Bats In The Americas And The Associated Risk To Cattle, Dana N. Lee, Monica Papeş, Ronald A. Van Den Bessche Aug 2012

Present And Potential Future Distribution Of Common Vampire Bats In The Americas And The Associated Risk To Cattle, Dana N. Lee, Monica Papeş, Ronald A. Van Den Bessche

KIP Articles

Success of the cattle industry in Latin America is impeded by the common vampire bat, Desmodus rotundus, through decreases in milk production and mass gain and increased risk of secondary infection and rabies. We used ecological niche modeling to predict the current potential distribution of D. rotundus and the future distribution of the species for the years 2030, 2050, and 2080 based on the A2, A1B, and B1 climate scenarios from the Intergovernmental Panel on Climate Change. We then combined the present day potential distribution with cattle density estimates to identify areas where cattle are at higher risk for the …

Sharing Science: A Study On The Effects Of Informal Science Education Outreach With Elementary Students, Martha Jo Vargas, Diane L. Marshall, Teresa E. Sheldahl Aug 2012

Sharing Science: A Study On The Effects Of Informal Science Education Outreach With Elementary Students, Martha Jo Vargas, Diane L. Marshall, Teresa E. Sheldahl

Biology ETDs

Science education reform has prompted scientists, engineers, and politicians alike to act on the growing need for improved educational programs in the STEM fields. Informal science programs that provide an educational experience outside of a traditional classroom and involve students on real-life and hands-on experiments are among these initiatives. It is hypothesized that informal science programs may increase students interest and performance in science and related subjects. Here we evaluate this by assessing the impacts of one such program, the Junior Scientist Outreach Program (JSOP), a weeklong, free-of-cost camp with fourth and fifth grade students in a predominately Hispanic/Latino community …

The Birth Of Radio In The American Sector (Rias)And Its Role During The Berlin Blockade, J. David Mecham Aug 2012

The Birth Of Radio In The American Sector (Rias)And Its Role During The Berlin Blockade, J. David Mecham

Theses and Dissertations

The ensuing chaos and power struggles between the East and West following the end of the Second World War in Germany set the stage for the creation of a unique radio station that would broadcast from behind the iron curtain for the duration of the cold war. RIAS, or Radio in the American Sector, would play a key role in the battle over ideology between the West and the Soviet Union. The story of RIAS' birth and development is a unique narrative of unintended consequences as the efforts of the Soviet Union to gain a monopoly over the airwaves of …

A Study Towards Development Of An Automated Haptic User Interface (Ahui) For Individuals Who Are Blind Or Visually Impaired, Ravi Rastogi Aug 2012

A Study Towards Development Of An Automated Haptic User Interface (Ahui) For Individuals Who Are Blind Or Visually Impaired, Ravi Rastogi

Theses and Dissertations

An increasing amount of information content used in schools, work and everyday living is being presented in graphical form, creating accessibility challenges for individuals who are blind or visually impaired, especially in dynamic environments, such as over the internet. Refreshable haptic displays that can interact with computers can be used to access such information tactually. Main focus of this study was the development of specialized computer applications allowing users to actively compensate for the inherent issues of haptics when exploring visual diagrams as compared to vision, which we hypothesized, would improve the usability of such devices.

Trade In A 'Green Growth' Development Strategy, Jaime De Melo Aug 2012

Trade In A 'Green Growth' Development Strategy, Jaime De Melo

Fondazione Eni Enrico Mattei Working Papers

The paper surveys the state of knowledge about the trade-related environmental consequences of a country’s development strategy along three channels: (i) direct trade-environment linkages (overexploitation of natural resources and trade-related transport costs);(ii) ‘virtual trade’ in emissions resulting from production activities; (iii) the product mix attributes of a ‘green-growth’ strategy (environmentally preferable products and goods for environmental management). Main conclusions are the following. Trade exacerbates over-exploitation of natural resources in weak institutional environments, but there is little evidence that differences in environmental policies across countries have led to significant ‘pollution havens’. Trade policies to ‘level the playing field’ would be ineffective …

A Two-Hundred Year History Of Ornithology, Avian Biology, Bird Watching, And Birding In Kansas (1810–2010), Thomas G. Shane Aug 2012

A Two-Hundred Year History Of Ornithology, Avian Biology, Bird Watching, And Birding In Kansas (1810–2010), Thomas G. Shane

Zea E-Books Collection

The first two centuries of bird study in Kansas essentially can be split into 50 year intervals since Zebulon Pike’s 1810 publication, an account of his explorations. The first 50 years were records of explorers crossing Kansas collecting bird specimens; many were Army doctors. The second half of the 19th Century was a continuation of explorers and those affiliated with museums obtaining bird specimens and the establishment of colleges and universities with faculty members also collecting birds and making observations. The first half of the 20th Century was a period of college faculties primarily composed of vertebrate zoologists who had …

Impact Of Salt On Denitrification Potential In Roadside Environments, Nakita A. Lancaster Aug 2012

Impact Of Salt On Denitrification Potential In Roadside Environments, Nakita A. Lancaster

Master's Theses

Urban systems are impacted by changes in hydrology and water chemistry, altering their ability to mitigate detrimental impacts to coastal water bodies, particularly those that result from high volumes of stormwater runoff. The elevated level of impervious cover increases not only runoff but also contaminant loading of nutrients, metals, and road salt used for deicing in cold weather climates. Current stormwater management strategies, while focused on managing the changes in hydrology associated with urbanization, also are designed to mitigate the pollutant loading. Here we investigate the impact that road salt will have on nitrogen removal in roadside environments. Sediments were …

Morzillo, Seth P. D. Riley, Travis Longcore

Cities and the Environment (CATE)

Urbanization poses many threats for many wildlife species. In addition to habitat loss and fragmentation, non-target wildlife species are vulnerable to poisoning by rodenticides, especially acutely toxic second generation anticoagulant rodenticides (SGARs). Although such poisonings are well documented for birds and mammals worldwide, the pathways by which these widely available compounds reach non-target wildlife have not been adequately studied, particularly in urban landscapes. Long-term studies of wild carnivores in and around Santa Monica Mountains National Recreation Area, a national park north of Los Angeles, have documented >85% exposure to anticoagulant rodenticides among bobcats, coyotes, and mountain lions. To investigate potential …

Fine-Scale Habitat Use Of Reintroduced Black-Footed Ferrets On Prairie Dog Colonies In New Mexico, Jennifer G. Chipault, Dean E. Biggins, James K. Detling, Dustin H. Long, Robin M. Reich Aug 2012

Fine-Scale Habitat Use Of Reintroduced Black-Footed Ferrets On Prairie Dog Colonies In New Mexico, Jennifer G. Chipault, Dean E. Biggins, James K. Detling, Dustin H. Long, Robin M. Reich

Western North American Naturalist

Black-footed ferrets (Mustela nigripes) are among the most endangered animals in North America. Reintroductions of captive-born ferrets onto prairie dog (Cynomys spp.) colonies are crucial to the conservation of the species. In September 2007, captive-born ferrets were released on a black-tailed prairie dog (Cynomys ludovicianus) colony at the Vermejo Park Ranch, New Mexico. Ferret kits experimentally released in areas of comparatively low and high prairie dog burrow densities were located via spotlight surveys. Some maturing ferret kits were subsequently translocated to areas of low and high burrow densities on nearby prairie dog colonies. For 2 …

Statehouse Mosaics And The American Electorate: How State Legislatures Affect Political Participation, Robynn Kuhlmann

LSU New Orleans Theses and Dissertations

Comparatively few studies have explored how variations in state governing institutions influence voting behavior. Utilizing lower chamber state legislative election returns from the years 2000 through 2010, and the 2002 through 2010 GSS data series, this dissertation focuses on how US state legislatures influence voting behavior and political attitudes of the American electorate. Specifically, this research takes on a comparative approach and illustrates how institutional differences in the size, capacity, and composition of the US state legislatures affect the electorates’ propensity to vote and how politically efficacious people feel.

A Framework To Annotate The Uncertainty For Geospatial Data, Zhao Yang Aug 2012

A Framework To Annotate The Uncertainty For Geospatial Data, Zhao Yang

LSU New Orleans Theses and Dissertations

We have developed a new approach to annotate the uncertainty information of geospatial data. This framework is composed of a geospatial platform and the data with uncertainty. The framework supports geospatial sources such as Geography Markup Language (GML) with uncertainty information. The purpose of this framework is to integrate the uncertainty information of data from the application users and thereby ease the development of processing uncertainty information of geospatial data. Having well organized data and using this framework, the end-users can store the uncertainty information on the current geospatial data structure. For example, a GIS user can share the error …

Trouble Every Day, Nina E. Schwanse

LSU New Orleans Theses and Dissertations

My interests lie in the intersection of the public and private, the corporate and personal, especially with regard to self-representation within cultural power structures. Utilizing video and web technologies, performance, and painting, I create imagined realms of fantasy, desire, obsession, and anxiety. Operating within, but not bound by, feminist discourse, my work explores the vehicles and effects by which both analog and digital technologies influence the relationship between the self and the object of desire (whether physical or virtual, interior or exterior to the body) and have produced both progressive and regressive offspring. By performing the role of both producer …

Ethnic Diversity And Poverty: A Dynamic Panel Study Of Illinois Counties, Ambuj Neupane Aug 2012

Ethnic Diversity And Poverty: A Dynamic Panel Study Of Illinois Counties, Ambuj Neupane

Master's Theses - Economics

Ethnic diversity’s effects on factors of economic development have been studied widely in recent years. I expand upon this research by directly studying ethnic diversity’s effects on the poverty rates within the counties of Illinois, using a dynamic panel technique devised by Blundell and Bond (1998). My results are consistent with the noted effects in previous literature, and provide extra weight towards measures of fractionalization and polarization. I conclude with policy implications and limitations which require future research.

Understanding Land Use Grain: An Evaluation Of Meaning And Measurement, Benjamin N. Williams Aug 2012

Understanding Land Use Grain: An Evaluation Of Meaning And Measurement, Benjamin N. Williams

LSU New Orleans Theses and Dissertations

Land use grain is a commonly-used measure of the mixture of land uses in the urban environment in transportation planning and public health, but there is no standard measurement practice in place. This thesis examines the meaning and common measurements of land use grain in these subfields. The entropy-based equation, the jobs-to-housing ratio, and the Herfindahl-Hirschman Index (HHI) are among the most common measures of land use grain, but results from these metrics differ depending upon how researchers choose a sample area and upon how land use categories are defined. All three metrics are performed, in a single context with …
