The Effects Of Total Dissolved Solids On Locomotory Behavior And Body Weight Of Streamside Salamanders, And A Baseline Survey Of Salamander Diversity And Abundance, Meghan Pascuzzi

Electronic Theses and Dissertations

Increased levels of total dissolved solids (TDS) in stream habitats are of concern due to salinity as well as the presence of potentially toxic ions. Natural gas drilling in the Marcellus shale could increase TDS in nearby streams. This thesis investigated the effects of water with elevated TDS on the locomotory activity and body weight of the streamside salamander Desmognathus ochrophaeus. Salamanders were exposed to water collected from streams in southwest Pennsylvania with elevated TDS as well as synthetic ion solutions that mimicked the ionic composition found in streams. Chronic, but not acute exposure to solutions of 1000 ppm TDS …

The Effect Of Resveratrol On Lipopolysaccharide-Induced Dopaminergic Deficits And Bv-2 Cell Activation, Katherine Marie Rose

Electronic Theses and Dissertations

Neuroinflammation is a common pathology found in patients with Parkinson's disease (PD). PD involves a loss of dopamine (DA) neurons and an increase in activated microglia with subsequent proinflammatory cytokine secretion in the substantia nigra (SN) and striatum. A loss of DA neurons is found in the offspring of animals exposed prenatally to the bacteriotoxin, lipopolysaccharide (LPS) (Ling et al., 2002). Activation of the extracellular regulated kinases, ERK1/2 and ERK5, the downstream targets in the mitogen-activated protein kinase (MAPK) pathway, has been shown to be involved in the dysregulation of the inflammatory process (Cuschieri and Maier, 2005). Consequently, LPS-induced activation …

Characterization Of The Hepatitis C Virus Genome Interactions With The Microrna Mir-122: Potential New Therapeutic Targets For Peptide Nucleic Acid Based Strategies, Valerie Schrott

Electronic Theses and Dissertations

Hepatitis C virus (HCV), a positive-sense RNA virus that chronically infects between 2.7 and 3.9 million Americans, is highly mutational, making the HCV infection difficult to treat. Thus, it is of high interest to search for highly conserved therapeutic targets within the HCV genome. Two such sequences are located within the 5' untranslated region (UTR) of HCV, being complementary for the microRNA miR-122, a liver microRNA essential for the production of the infectious virus. The use of peptide nucleic acids (PNAs) as therapeutic agents has become a promising area of study in recent years. In this study, we characterized the …

Depictions Of Mental Disorder In Mainstream American Film 1988-2010, Catherine A. Sherman

Electronic Theses and Dissertations

The following qualitative research study examined visual and thematic depictions of mental disorder in mainstream American film from 1988 to 2010. The research was an extension of an earlier investigation on portrayals of psychological disability in Hollywood movies (Levers, 1988, 2001). The theoretical and historical grounding for the project included Sander Gilman's (1982) scholarship on madness in the pictorial arts, the history and treatment of mental disorder over the course of time, social constructionism and the media, and research on media depictions of mental illness. The author employed two content analysis instruments (Levers, 1988, 2001) to record the appearance of …

Rooftop Gardening In An Urban Setting: Impacts And Implications, Lisa Barreiro

Electronic Theses and Dissertations

Research on green roofs has focused on grasses, sedums, and forbs. The aims of this thesis were to determine the potential of rooftop gardens (RTGs) in an urban setting to reduce local levels of CO2, remediate storm water runoff, and provide boutique vegetables for a restaurant. The garden roof footprint was 238 ft2, with 14% covered by vegetated boxes. The soil mixture used had 96% absorbency with 54.12 gallons of the 55 gallons of precipitation that fell within the rain catcher boxes absorbed. Total biomass production was 37.98 Kg of wet biomass and 5.04 Kg of dry biomass. The amount …

The Triptych Tetrad: Marshall Mcluhan's Neo-Medieval Communication Theory, Anthony Wachs

Electronic Theses and Dissertations

The work of Marshall McLuhan has often been reduced to the form of catchphrases and "McLuhanisms," such as the "global village" and "the medium is the message" in the field of communication. Though these phrases capture an aspect of his thought, the scholarly understanding of McLuhan's vision remains incomplete, even within the specialized area of Media Ecology, of which McLuhan is recognized as the intellectual father. Throughout his corpus, McLuhan makes reference to the classical and medieval trivium, which was the basis for education throughout Western history until the Renaissance. Indeed, he developed a history of the trivium up to …

The Impact Of Participation In A Secondary School-Based Mentoring Program On Urban Females After High School Graduation, Sandra Lee Wesolowski

Electronic Theses and Dissertations

As thoughts of the future weigh heavily on many adolescents' minds, the at-risk urban adolescent female are at an especially critical point; every decision she makes on a daily basis has the potential to affect the rest of her life (Way, 1995). However, secondary school-based mentoring programs can provide the modality to intervene with at-risk urban adolescent females to increase the likelihood of success both while in high school and after high school graduation.

This study is a phenomonologically-oriented qualitative study that asks the question: What is the impact of participation in a secondary school-based mentoring program on the lives …

Chromate Reduction By Desulfovibrio Desulfuricans Atcc 27774, Ning Zhang

Electronic Theses and Dissertations

Chromium has been used extensively in the industry process of metal refinishing and electroplating. It is also a byproduct of the processing of fissionable materials at United States Department of Energy facilities. Chromate (Cr (VI)) is soluble and readily absorbed by cells, while the reduced form of chromium, Cr (III), is insoluble. Thus means of reducing Cr (VI) to Cr (III) in the environment is a potential means of remediation. Desulfovibrio desulfuricans strain 27774 is a sulfate reducing bacterium that can reduce Cr (VI). It also can respire nitrate to ammonia. As some sites of chromium contamination also contain high …

Synthesis Of Furo[2,3-D]Pyrimidines, Thieno[2,3- D]Pyrimidines, Pyrrolo[2,3-D]Pyrimidines As Classical And Nonclassical Antifolates, Receptor Tyrosine Kinase (Rtk) Inhibitors And Antimitotic Agents, Xin Zhang

These compounds were synthesized and evaluated as single and/or muliple targeted classical and nonclassical antifolates to decrease toxicity and improve the antitumor activity and selectivity of existing therapeutic …

Temporal And Spatial Assessment Of Pahs In Water, Sediment, And Oysters As A Result Of The Deepwater Horizon Oil Spill, Meghan Christina Dailey

Electronic Theses and Dissertations

On April 20, 2010, BP's Deepwater Horizon oil rig exploded leaking over 200 million gallons of crude oil into the Gulf of Mexico for 84 days. Exposure to oil-associated polycyclic aromatic hydrocarbons (PAHs) in the water and sediment could severely impact the aquatic organisms inhabiting the Gulf of Mexico (i.e. developmental defects, reproductive effects, death, etc.). Therefore, water, sediment and oyster, Crassostrea virginica, samples were collected approximately bimonthly between May 26 and November 30, 2010 from multiple sites along the Gulf Coast, namely, two sites in Mobile Bay (Denton and Sand Reefs at 1 or 0.1 m above the bay …

Reconfigurable Wideband Circularly Polarized Microstrip Patch Antenna For Wireless Applications, Ahmed Khidre

Electronic Theses and Dissertations

In this thesis, developments of rectangular microstrip patch antenna to have circular polarization agility with wideband performance, for wireless applications are presented. First, a new technique to achieve circularly polarized (CP) probe feed single-layer microstrip patch antenna with wideband characteristics is proposed. The antenna is a modified form of the popular E-shaped patch, used to broaden the impedance bandwidth of a basic rectangular patch antenna. This is established by letting the two parallel slots of the E-patch unequal. Thus, by introducing asymmetry two orthogonal currents on the patch are excited and circularly polarized fields are realized. The proposed technique exhibits …

Picking Up The Pieces, Michael Presley Satterfield

Electronic Theses and Dissertations

Over time wooden and metal objects, such as utility poles, construction lumber, parts from cars, trucks, farm equipment, and heavy machinery, and even an old abandoned car, have become unserviceable and discarded. Lying useless until discovered by the creative explorer, they are reclaimed and become precious raw materials in an artistic project. This body of work is about our ability to pick up the pieces after a time of being at a low point in life. It is about being uplifted by a companion, memory, or idea to a better state of mind or place. The materials I choose for …

There Is No Dishonor In Desertion: Army Racial Intolerance And African-American Soldiers' Desertion, Steve Wallace

Electronic Theses and Dissertations

The thesis focuses on a study concerning the desertion of African-American soldiers from the United States Army. The data were collected from the period covering the War of Independence to the mid-1960s of the Cold War. The study proposes that there are limits to which these soldiers cannot bear the burden of combat and the simultaneous fight against institutionalized racism. Some men endured their circumstances in spite of pervasive intolerance, but others simply could not make sense of the inconsistencies of their government's requirement for them to fight yet deny them basic human rights. The men believed they had the …

The Relative Effects Of Mindfulness And Values On Therapeutic Relationship: Developing Methods Of Manipulating Alliance, Regan Michelle Slater

Electronic Theses and Dissertations

Comfactors research indicates that there is a positive relationship between therapeutic relationship and improved client outcomes. However, little research has been done to examine the nature of this relationship. The current study examined the relationship between mindfulness, values, and working alliance. Participants were 59 undergraduate students who were randomly assigned to one of three conditions: mindfulness plus values, mindfulness, or control. Depending on condition, participants engaged in a mindfulness plus values exercise, a mindfulness exercise, or a wait control. All participants then engaged in a conversation with the experimenter regarding a recent disagreement. Mindfulness and values connectedness were assessed pre-intervention, …

Estimating The Effects Of Condemned Inmates' Last Statements On Public Opinion About The Death Penalty: A Factorial Survey Approach, Timothy P. Colyer

Electronic Theses and Dissertations

There has been an increase in writings that address the last statements of condemned offenders. Many of these writings suggest that exposure to the humanity sometimes exhibited in these last statements may steer public opinion against the death penalty. This dissertation tests this suggestion by exposing 400 participants to randomly generated vignettes containing various capital crimes, demographic characteristics, and last statements. The survey data are analyzed utilizing multilevel modeling. Study results include the effects of varying levels of demonstrated humanity in the last statements of condemned offenders on public opinion, and whether specific demographic characteristics appear to influence study participant …

Coaching In An Interactive Virtual Reality To Increase Fidelity Of Implementation Of Discrete Trial Teaching, K.M. Vince Garland

Electronic Theses and Dissertations

In teacher preparation, more effective pathways and practices are needed for preparing, placing, and supporting beginning teachers and principals (Darling-Hammond, 2010; U.S. Department of Education, 2009b). A common issue in the field of special education is the lack of skill transfer from one setting to another (Dieker, Hynes, Hughes, & Smith, 2008). It has been posited that “practicing up” is not ethical in that novice teachers must attempt to teach with a limited knowledge of appropriate pedagogy and skill (Dieker et al., 2008). The new challenge becomes finding an effective mechanism that provides essential learning experiences and opportunities to refine …

Image Degradation Due To Surface Scattering In The Presence Of Aberrations, Narak Choi

Electronic Theses and Dissertations

This dissertation focuses on the scattering phenomena by well-polished optical mirror surfaces. Specifically, predicting image degradation by surface scatter from rough mirror surfaces for a two-mirror telescope operating at extremely short wavelengths (9nm~30nm) is performed. To evaluate image quality, surface scatter is predicted from the surface metrology data and the point spread function in the presence of both surface scatter and aberrations is calculated. For predicting the scattering intensity distribution, both numerical and analytic methods are considered. Among the numerous analytic methods, the small perturbation method (classical Rayleigh-Rice surface scatter theory), the Kirchhoff approximation method (classical BeckmanKirchhoff surface scatter theory), …

With The Protection Of The Gods: An Interpretation Of The Protector Figure In Classic Maya Iconography, Tiffany M. Lindley

Electronic Theses and Dissertations

Iconography encapsulates the cultural knowledge of a civilization. The ancient Maya of Mesoamerica utilized iconography to express ideological beliefs, as well as political events and histories. An ideology heavily based on the presence of an Otherworld is visible in elaborate Maya iconography. Motifs and themes can be manipulated to convey different meanings based on context. An example of this mutability can be witnessed in the depiction of Otherworld gods. Maya gods were not like Old World pantheons; gods were fluid and could function in multiple roles. Protector gods are an example of the fluidity of Maya deities. Scenes of protector …

The Sustainability Of Overconsumption? A Discursive Analysis Of Walmart's Sustainability Campaign, Kathleen Adams

Electronic Theses and Dissertations

This study inquires as to whether Walmart’s sustainability campaign represents a sincere and holistic change throughout the company’s global supply chain or if it is simply a public relations campaign which caters to the growing target market of “next-generation” consumers and justifies further expansion into “emerging markets”. A critical analysis of Walmart’s sustainability discourse is presented, using transcribed texts of various corporate and publicitygeared publications. Frequently utilized terms and themes are identified throughout the big-box retailer’s sustainability campaign which convey a distinctly Neoliberal ethos—a political economy which lies at the heart of current practices of institutional unsustainability—and emphasize the role …

Genetic Engineering As Literary Praxis: A Study In Contemporary Literature, Taylor Evans

Electronic Theses and Dissertations

This thesis considers the understudied issue of genetic engineering as it has been deployed in the literature of the late 20th century. With reference to the concept of the enlightened gender hybridity of Cyborg theory and an eye to ecocritical implications, I read four texts: Joan Slonczewski's 1986 science fiction novel A Door Into Ocean, Octavia Butler's science fiction trilogy Lilith's Brood – originally released between 1987 and 1989 as Xenogenesis – Simon Mawer's 1997 literary novel Mendel's Dwarf, and the first two books in Margaret Atwood's speculative fiction MaddAddam series: 2003's Oryx and Crake and 2009's The Year Of …

The Effect Of Civics-Based Video Games On Middle School Students' Civic Engagement, John Charles Pagnotti Jr

Electronic Theses and Dissertations

Democratic theorists argue that democratic institutions thrive when the citizens of the society robustly participate in governance (Galston, 2004; Barber, 2001). A traditional indicator of democratic participation is voting in elections or referendums. However, democratic apologetics posit that humans need to be trained in democratic processes in order to be democratic citizens (Dewey, 1916; Gutmann, 1990; Sehr, 1997; Goodlad, 2001). Citizens need to know not only the protocol of participation, they also need to be trained in the processes of mind (Dewey, 1916; 1927). Educational systems in this country have been the traditional place where democratic training has been vested …

A Production And Cost Modeling Methodology Of 2nd Generation Biofuel In The United States, David A. Poole

Electronic Theses and Dissertations

The use of biofuels in the United States has increased dramatically in the last few years. The largest source of feedstock for ethanol to date has been corn. However, corn is also a vitally important food crop and is used commonly as feed for cattle and other livestock. To prevent further diversion of an important food crop to production of ethanol, there is great interest in developing commercial-scale technologies to make ethanol from non-food crops, or other suitable plant material. This is commonly referred to as biomass. A review is made of lignocellulosic sources being considered as feedstocks to produce …

Thermal Stability Characteristics Of Fisher-Tropsch And Hydroprocessed Alternative Aviation Fuels In A Fixed Bed Reactor, Sergio Quintero

Electronic Theses and Dissertations

Growing prices, limited supply, and public concern about greenhouse gases associated with crude-derived jet fuels have led to development of renewable alternatives which must be compatible with the worldwide civilian and military aviation infrastructure, which were designed for operation with Jet-A/JP-8. Any alternative fuel should not have negative effects on the aircraft engines and fuel systems, especially from a thermal stability perspective, since any adverse effect of the physical properties, and chemical composition, including existence of trace elements, of those fuels may only be revealed after extensive operation, resulting in higher life-cycle maintenance and operation costs. This study considered four …

Mathematic Strategies For Teaching Problem Solving: The Influence Of Teaching Mathematical Problem Solving Strategies On Students' Attitudes In Middle School, Kelly Lynn Klingler

Electronic Theses and Dissertations

The purpose of this action research study was to observe the influence of teaching mathematical problem solving strategies on students’ attitudes in middle school. The goal was to teach five problem solving strategies: Drawing Pictures, Making a Chart or Table, Looking for a Pattern, Working Backwards, and Guess and Check, and have students reflect upon the process. I believed that my students would use these problem solving strategies as supportive tools for solving mathematical word problems. A relationship from the Mathematics Attitudes survey scores on students’ attitudes towards problem solving in mathematics was found. Students took the Mathematics Attitudes survey …

Factors Limiting Native Species Establishment On Former Agricultural Lands, Annalisa M. Weiler-Lazarz

Electronic Theses and Dissertations

Restoration of abandoned, nonnative species-dominated agricultural lands provides opportunities for conserving declining shrubland and grassland ecosystems. Land-use legacies, such as elevated soil fertility and pH from agricultural amendments, often persist for years and can favor nonnative species at the expense of native species. Understanding the factors that limit native species establishment on abandoned agricultural lands can provide important insights for restoration and conservation of native species on human-modified lands. I conducted two field experiments on abandoned agricultural lands: a former pasture on Martha’s Vineyard, MA and a former citrus grove at Merritt Island National Wildlife Refuge (MINWR) in Titusville, FL. …
