Erection Of Ibirhynchus Gen. Nov. (Acanthocephala: Polymorphidae), Based On Molecular And Morphological Data, Martin Garcia-Varela, Gerardo Pérez-Ponce De León, Francisco J. Aznar, Steven A. Nadler

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The genus Southwellina is composed of 3 described species, i.e., S. hispida (the type species), S. dimorpha, and S. macracanthus. All 3 are endoparasites of fish-eating birds that have worldwide distributions. Morphologically, the genus is characterized by possessing a short and compact trunk, 2 fields of spines in the anterior region of the trunk (in at least 1 sex), a short cylindrical proboscis (sometimes with a swollen region armed with numerous longitudinal rows of hooks), a double-walled proboscis receptacle, and 4 tubular cement glands in males. In the current study, specimens identified as S. dimorpha were collected from …

A Perspective On Thirty Years Of The Webb, Pearman And Leuning Density Corrections, Xuhui Lee, William J. Massman

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The density correction theory of Webb et al. (1980, Q J Roy Meteorol Soc 106: 85–100, hereafter WPL) is a principle underpinning the experimental investigation of surface fluxes of energy and masses in the atmospheric boundary layer. It has a long-lasting influence in boundary-layer meteorology and micrometeorology, and the year 2010 marks the 30th anniversary of the publication of the WPL theory. We provide here a critique of the theory and review the research it has spurred over the last 30 years. In the authors’ opinion, the assumption of zero air source at the surface is a fundamental novelty that …

An Exploratory Investigation Of Polar Organic Compounds In Waters From A Lead–Zinc Mine And Mill Complex, Colleen E. Rostad, Christopher J. Schmitt, John G. Schumacher, Thomas J. Leiker

United States Geological Survey: Staff Publications

Surface water samples were collected in 2006 from a lead mine–mill complex in Missouri to investigate possible organic compounds coming from the milling process. Water samples contained relatively high concentrations of dissolved organic carbon (DOC; greater than 20 mg/l) for surface waters but were colorless, implying a lack of naturally occurring aquatic humic or fulvic acids. Samples were extracted by three different types of solid-phase extraction and analyzed by electrospray ionization/mass spectrometry. Because large amounts of xanthate complexation reagents are used in the milling process, techniques were developed to extract and analyze for sodium isopropyl xanthate and sodium ethyl xanthate. …

The Effects Of Historic Earthen Barriers On Northern New England Tital Marshes, Jordan W. Mora

Master's Theses and Capstones

Berms, defined as historic earthen barriers, represent one type of hydrological modification introduced by humans in the tidal marshes of northern New England. Three different research approaches were applied to study the impact of berms on various tidal marsh dynamics. The descriptive study shows that restricted flooding from berm interference can result in significantly altered physical gradients in addition to landward subsidence and pool development. The results from the transplant experiment indicate that the altered landward structure affects the relative importance of biological interactions, namely herbivory, in controlling plant species distribution. The predictive GIS analyses illustrate the location of 34 …

Regional Harmonization Procedure For Prioritization Of Recycled Material Specifications, Courtney Goldstein

Master's Theses and Capstones

Widely varying recycled material requirements across state lines has been perceived as a significant barrier to greater use of recycled materials in highway construction by state contractors and industry. The goal of this thesis is to create a procedure to compile, compare, contrast and finally synthesize documents that support a priority list of recycled materials and applications for which material specifications can be harmonized among regional states in the US.

This work compiled background research on selected materials and related regulations into standardized templates. The information analyzed was communicated with EPA, FHWA, and state representatives to approve a breakdown priority …

The transdisciplinary field of agroecology provides a platform for experiential learning based on an expanded vision of research on sustainable farming and food systems and the application of results in creating effective learning landscapes for students. With increased recognition of limitations of fossil fuels, fresh water, and available farmland, educators are changing focus from strategies to reach maximum yields to those that feature resource use efficiency and resilience of production systems in a less benign climate. To help students deal with complexity and uncertainty and a wide range of biological and social dimensions of the food challenge, a whole-systems approach …

Toward An Environmental Conservatism, Terri S. Winters

Master's Theses and Capstones

The Evangelical Climate Initiative (ECI) argues that climate change is real and human-induced and represents a moral challenge for Christians to which an urgent response is required. The ECI demonstrates that there is common ground between conservatism and environmentalism. The actions of the ECI fit within an "environmental conservatism" whose elements have historical precedence. We find the seeds of parallel ideas in the writings of the Southern Agrarians in the 1920s and 1930s---ideas that were brought to full flower by Richard Weaver, an important figure in the development of a post-World War II traditional conservatism. We also find a similar …

Usa Vs China; Energy Security Politics Challenges Of Peak-Oil And Climate Change, Tania Hoppe

Dissertations and Theses

"Energy is a critical basis for state survival. This thesis aims at examining the different energy-security strategies of the USA and China and the political means necessary to implement clean-energy development beyond marginal results. The success of China’s lead in its devotion to clean-energy production raises the question of what infrastructural and political challenges the US must overcome to further develop its clean energy industry. While China focuses on its competitive edge in the global energy market, can its domestic energy goals offset population density and addiction to coal? Despite economic competitiveness that comes with market globalization, society’s only means …

Laser Induced Breakdown Spectroscopy For Detection Of Organic Residues Impact Of Ambient Atmosphere And Laser Parameters, Christopher G. Brown

Electronic Theses and Dissertations

Laser Induced Breakdown Spectroscopy (LIBS) is showing great potential as an atomic analytical technique. With its ability to rapidly analyze all forms of matter, with little-to-no sample preparation, LIBS has many advantages over conventional atomic emission spectroscopy techniques. With the maturation of the technologies that make LIBS possible, there has been a growing movement to implement LIBS in portable analyzers for field applications. In particular, LIBS has long been considered the front-runner in the drive for stand-off detection of trace deposits of explosives. Thus there is a need for a better understanding of the relevant processes that are responsible for …

A Green Board As A Climate-Change Imperative: Appointing A Climate-Change Expert To The Audit Committee, Porcher L. Taylor Iii, Harris L. Kay

School of Professional and Continuing Studies Faculty Publications

This article makes the innovative and timely case for a climate change imperative: a green board. Urgency is evident, with the arrival of "a fast-emerging new burden on board members to oversee their company's posture on climate change and to begin monitoring an area that, until now, has drawn scant attention in the boardroom."²¹ One major impetus for the proposal advocated in this Article is that there is apparently a dearth of green boards in corporate America.²² In contrast, European and Canadian companies appear to be at the vanguard of utilizing green boards.²³

Encontrando La Comida Saludable: Identifying Food Access Barriers For The Adams County, Pennsylvania Latino Community, Gwendolyn D. Brown, Olivia A. Haddad

Student Publications

Overwhelming research indicates that recent national trends in U.S. food systems have led to the increased prevalence of processed foods and associated diet-related diseases. The effects of unhealthy diets have been distributed unevenly across the country’s socioeconomic and ethnic groups. Certain socioeconomic and ethnic groups face greater geographic, financial and cultural barriers to healthy food access. In Adams County, Pennsylvania, Latinos comprise 5.6% of the population, making them the county’s largest minority group, yet little is known about the food access barriers they face. In this study, we used a combination of surveys and focus groups with Latino residents and …

Environmental scientists use advanced sensor technology such as meteorological towers, wireless sensor networks and robotic trams equipped with sensors to perform data collection at remote research sites. Because the amount of environmental sensor data acquired by such instruments is increasing, the ability to evaluate the accuracy of the data at collection time and to check that the instrumentation is operating correctly become critical in order to not lose valuable time and information. The goal of the research is to define a solution, based on software-engineering techniques, to support the scientist's ability to specify data properties that can identify anomalies in …

An Investigation Of The Seismic Hazards Of The El Paso-Juarez Region: The Nature And Extent Of The Southern East Franklin Mountains Fault Zone, Victor Manuel Avila

Open Access Theses & Dissertations

ABSTRACT

The El Paso-Ciudad Juarez Region is situated at the southern end of the active Rio Grande Rift within the Mesilla and Hueco basins. The Hueco basin is separated from the eastern Franklin Mountains by a prominent fault, the Eastern Boundary Fault. Studies of this fault have revealed fault scarps that displace Quaternary deposits (Keaton et al., 1995; Raney and Collins, 1990; Lovejoy, 1976). This fault is cataloged as an active fault in the National Seismic Hazard Map with an estimated slip rate of 0.1 mm/yr. A fault with similar characteristics as the Eastern Boundary Fault extends further to the …

Response To Violent Prone Female Adolescents: The Chicago Public School Approach, Marian E. Dozier

Dissertations

School violence has become increasingly more prevalent among adolescent females over the last ten years. As administrators, teachers, parents, and law enforcement officials try to control and decrease the number of violent incidents that occur in our schools, adolescent females continue to exhibit inappropriate and violent behavior at an alarming rate within our school communities. Adolescent females who behave badly have historically been overlooked or ignored, as girls have often been perceived as being incapable of demonstrating hostile conduct in an academic setting.

The purpose of this study was to investigate, describe, and analyze the frequency and nature of violent …

Firm Bidding Behavior In Highway Procurement Auctions: An Analysis Of Single-Bid Contracts, Tacit Collusion, And The Financial Impact On Kentucky, David R. Barrus

University of Kentucky Doctoral Dissertations

Recently, the American Association of State Highway and Transportation Officials (AASHTO) indicated lack of competition and single-bid contracts in asphalt paving as a major issue facing state transportation departments. Single-bid contracts indicate a lack of competition which increases costs to state and local governments. During the period from 2005-2007 in Kentucky, 42 percent of all bids were awarded with only one firm bidding on the project. Of the asphalt paving jobs, 63 percent of those jobs were awarded to a single bidder.

The analysis of this dissertation focuses on detecting tacit collusion in asphalt paving jobs in Kentucky. A focal …

Determining Anchoring Systems For Marine Renewable Energy Devices Moored In A Western Boundary Current, Michael G. Seibert

Electronic Theses and Dissertations 2010 - 2019

In this thesis anchoring systems for marine renewable energy devices are examined for an area of interest off the coast of Southeast Florida that contains both ocean current and thermal resources for future energy extraction. Bottom types observed during previous regional benthic surveys are compiled and anchor performance of each potential anchor type for the observed bottom types is compared. A baseline range of environmental conditions is created by combining local current measurements and offshore industry standards. Numerical simulations of single point moored marine hydrokinetic devices are created and used to extract anchor loading for two potential deployment locations, multiple …
