Potential Stormwater Runoff Reductions By Incorporating Low Impact Development: Rocky Branch Watershed, Columbia, Sc, Brett Sexton

Theses and Dissertations

Urbanization and increasing population are primary sources of water degradation, increased flood risks, and channel morphological instability. Impervious surface areas increase with urbanization and result in decreased infiltration capactities, increased stormwater runoff, and more rapid stormwater delivery, which in turn increase flood magnitudes and frequencies. Low impact development (LID) can provide volumetric detention storage to reduce flooding. This thesis reviews types of LID, their attributes and limitations, and examines how effectively they can abstract storm runoff volumes, reduce peak discharge, and delay stormwater arrival times for relatively frequent storm events in the Rocky Branch Watershed (RBW).

The RBW is 50% …

Do Americans’ Perceptions Of The Prevalence Of Prejudice Impact Their Racial Policy Preferences? Investigating Meta-Stereotypes As A Potential Causal Mechanism, Alexandra Reckendorf

Theses and Dissertations

Racial discrimination, though more subtle than in the past, is still an enduring presence in 21st century America. Whether looking at education, health care, the workforce, housing/lending practices, or the criminal justice system, studies routinely confirm that racial prejudice and discrimination persist despite claims of a “post-racial” America. Yet, despite the perseverance of racial prejudice and discrimination, policies correcting racial injustice remain contentious, either failing to receive the requisite support to pass reforms or receiving backlash from the public. This project explores meta-stereotypes in the Black and white communities, and highlights meta-stereotypes’ potential impact when determining why some individuals support …

Ghosts Of The Horseshoe: A Mobilization Of A Critical Interactive, Richard Lee Walker

Theses and Dissertations

Critical Interactives (CIs) are designed to harness the voluntary, reality-bending excitement of discovery as afforded by play, but to do so in the context of rules that mobilize procedural rhetoric to instantiate critical awareness. Critical interactives are not just about improving lives through code or education; rather, they establish a methodology for generating more aesthetic and reflective interactive experiences. To grasp more fully the logic underpinning CIs, we need to understand the powerful nature of interactivity and outline how such interactivity involves a notion of ethics, i.e., a way of living, in and through media practice.

An Investigation Of Mitochondrial Bioenergetics And The Turnover Of Succinated Proteins In The Adipocyte During Diabetes, Ross Tanis

Theses and Dissertations

We previously identified the chemical modification S-(2-succino)cysteine (2SC), which is formed when the Krebs cycle metabolite fumarate reacts with protein cysteine residues, also termed protein succination. Protein succination is increased in the adipose tissue of ob/ob and db/db mice in vivo and in 3T3-L1 adipocytes grown in high glucose in vitro. The increase in 2SC in the 3T3-L1 adipocyte occurs as a direct result of glucotoxicity and increased mitochondrial stress. We have shown that uncoupling agents, which lower mitochondrial stress, prevent the increase in succinated proteins.

In this study we examined the relationship between increased succination and mitochondrial bioenergetics in …

Geochemical Analysis Of Eolian Fluxes During The Transition From Greenhouse To Icehouse Conditions In Equatorial Pacific., Daniel Nicholas Miller

Theses and Dissertations

To assess the atmospheric conditions during times of differing pole to equator thermal gradients through the middle Eocene to early Oligocene, 42 to 30 Ma, samples from deep-sea sediment cores U1331, U1332, U1333 from IODP Expedition 320/321 in the eastern equatorial Pacific (EEP) have been chemically leached to isolate the operationally defined eolian dust (ODED; <63 μm fraction). The ODED was analyzed for neodymium (Nd) isotopic compositions and rare earth element (REE) concentrations in order to determine the provenance of the ODED fraction and to elucidate the environmental conditions (e.g. predominant wind patterns) during deposition over the interval of study. The variations in the ODED fraction are expected to be controlled by changes in sources delivered via eolian input. However, negative cerium anomalies in the Post Achaean Australian Shale (PAAS) normalized rare earth element profiles of the ODED show a biasing geochemical seawater phase to the ODED signature. It is found that εNd values and cerium anomalies (Ce/Ce*) of ODED are consistent with fossil fish teeth values that record bottom water signatures from the same location and time period until ~36-37 Ma; around the Priabonian/Bartonian boundary marked by increased thermal gradients due to the emplacement of high elevation glaciers on Antarctica (Scher et. al., 2014). Moreover, the more negative cerium anomalies correlate to more radiogenic εNd values. The geochemical seawater signature in the ODED samples is believed to be caused by a change in sedimentary phase regulated by the spatial paleoposition of the sites relative to the biological high productivity zone and/or the depth of the CCD. Subsequently these regulators on the sedimentary phases of the ODED were investigated for biasing the geochemical signatures of the ODED, assumed to be changes in sources thereby provenance. Together, the Nd and REE results from the study temporally indicate that the ODED fraction may be a mixing between two sources, that of a biasing biogenic and/or authigenic source that records seawater conditions, and that of an older, less radiogenic continental source, inferred as Asian loess, as an increased thermal gradient prevails over the course of the study. Further research needs to be performed to make more robust and conclusive linkages between sources, mixing of sources, and atmospheric eolian delivery patterns, highlighting the necessity for a better understanding of atmospheric conditions during important climatic events throughout the history of the Earth.

Extending The Limits Of Solid Phase Microextraction, Shilpi Chopra

Seton Hall University Dissertations and Theses (ETDs)

Solid phase microextraction (SPME) is a solventless extraction technique that combines sample preparation and sample introduction into a gas chromatograph into a single step. For the past 20 years, solid-phase micro-extraction (SPME) has been used in numerous fields such as: food analysis, including juices, alcohols fruits and vegetables for volatiles, aroma, caffeine, fatty esters, environmental applications including volatile organic contaminants, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phenols, pesticides, steroids, herbicides, acid/neutral/base compounds, and organometallic compounds from water, air, soil, sludge, and sediment samples and in biomedical analysis.

This work demonstrates the extension of the limitations of SPME with respect to extraction …

Environment Stress And Increased Vulnerability To Impoverishment In Rural Ethiopia: Case Studies Evidence, Tesfaye Teklu

International Journal of African Development

Integral to the global trends in climate change, there are slow but notable long-term changes in level of weather (e.g. slow increase in temperature and decline in rainfall) accompanied with increased weather extremes such as increased frequency and intensity of drought in Ethiopia. These changes are occurring over large geographical area including the most populous and arable highlands. Rural households in these environmentally stressed areas employ multiple strategies to manage environmental risk. However, as evident from the empirical regularities below, vulnerability to poverty persists because of households’ diminished capacity to mitigate and cope with frequent occurrence of weather extremes. The …

Maternal Education, Linkages And Child Nutrition In The Long And Short-Run: Evidence From The Ethiopia Demographic And Health Surveys, Ambel Alemayehu Azeze, Wei-Chiao Huang

International Journal of African Development

We used the 2000 and 2005 Ethiopian Demographic and Health Surveys to analyze the effect of maternal education and its pathways on chronic (long-run) and acute (short-run) malnutrition inEthiopia. The pathways examined in this study are socioeconomic status, maternal health-seeking behavior, maternal knowledge of health and family planning and reproductive behavior. We find that maternal education works through all except health-seeking behavior. We also find that maternal education and its pathways are more relevant and robust in explaining chronic than acute malnutrition. Socioeconomic status is the most important factor linking maternal education and child nutritional status. Although girls’ education is …

Characterization Of Ptls-Like Phenotypes In A Conditional Rai1 Transgenic Mouse Model And Study Of Rai1 Molecular Function, Lei Cao

Open Access Dissertations

Structural variants are abundant in the genomes of phenotypically normal populations. However, some rare structural variants are found to be disease causing. Potocki–Lupski syndrome (PTLS) is a genomic disorder associated with an 3 Mb duplication in 17p11.2. Clinical features include leanness, intellectual disability, autistic features and developmental deficits. RAI1 gene dosage is associated with the PTLS phenotypes. To understand where and when Rai1 overexpression is detrimental, we generated a mouse that over-expresses Rai1 conditionally in forebrain neurons (I-Rai1). Phenotypic characterization of I-Rai1 mice showed leanness, hyperactivity, and impaired learning and memory ability compared with wild-type littermates. Rai1 overexpression is controlled …

Typhoon Generated Surface Gravity Waves Measured By Nomad-Type Buoys, Clarence O. Collins Iii

Open Access Dissertations

This study examines wind-generated ocean surface waves as measured by NOMAD-type buoys during the ONR-sponsored Impact of Typhoons on the Ocean in the Pacific (ITOP) field experiment in 2010. 1-D measurements from two new Extreme Air-Sea Interaction (EASI) NOMAD-type buoys were validated against measurements from established Air-Sea Interaction Spar (ASIS) buoys. Also, during ITOP, 3 drifting Miniature Wave Buoys, a wave measuring marine radar on the R/V Roger Revelle, and several overpasses of JASON-1 (C- and Ku-band) and -2 (Ku-band) satellite altimeters were within 100 km of either EASI buoy. These additional measurements were compared against both EASI buoys. Findings …

Functional Roles Of Syngap1 In Early Embryonic Development Of Zebrafish, Bing Zou

Open Access Theses

De novo mutations of SYNGAP1 (Synaptic GTPase Activating Protein) have been found in human patients with intellectual disability, epilepsy and autism. Consistent with an important role for SYNGAP1 in nervous system development, mice heterozygous for SYNGAP1 loss-of-function mutations exhibit disrupted behavior and cognition. Studies in mice have focused on the role of SYNGAP1 at excitatory post-synapses even though SYNGAP1 is expressed prior to synaptogenesis. To study the potential roles of SYNGAP1 during early developmental stages, we carried out a syngap1 morpholino study in zebrafish and found that knockdown of syngap1 causes reduced brain size, increased cell death in the brain …

Carbon Dynamics On The Louisiana Continental Shelf And Cross-Shelf Feeding Of Hypoxia, Brian Fry, Dubravko Justic, Philip Riekenberg, Erick M. Swenson, R. Eugene Turner, Lixia Wang, Lora Pride, Nancy N. Rabalais, Janis C. Kurtz, John C. Lehrter, Michael C. Murrell, Elizabeth H. Shadwick, Brandon Boyd

Faculty Publications

Large-scale hypoxia regularly develops during the summer on the Louisiana continental shelf. Traditionally, hypoxia has been linked to the vast winter and spring nutrient inputs from the Mississippi River and its distributary, the Atchafalaya River. However, recent studies indicate that much of the shelf ecosystem is heterotrophic. We used data from five late July shelfwide cruises from 2006 to 2010 to examine carbon and oxygen production and identify net autotrophic areas of phytoplankton growth on the Louisiana shelf. During these summer times of moderate river flows, shelfwide pH and particulate organic carbon (POC) consistently showed strong signals for net autotrophy …

Provider Perception Of Patient Satisfaction If Antibiotics Are Not Given For Upper Respiratory Infection, Robyn Doniel Drake

Dissertations

The purpose of this project was to assess if advanced practice nurse practitioners perceived patient satisfaction of patients seen in Metropolitan Retail Clinics was improved after educational materials were given to explain when antibiotics work. I hypothesized that provider perception of patient satisfaction would decrease unnecessary prescribing of antibiotics after providing patient education? This project used questionnaires to collect data from control and intervention groups to demonstrate a gain in provider perception if patient satisfaction after education was given in the intervention group. The results of this project did not reveal to the primary investigator what was originally assumed, that …

Effects Of Pde4 Pathway Inhibition In Rat Experimental Stroke, Fan Yang, Rachita K. Sumbria, Dong Xue, Chuanhui Yu, Dan He, Shuo Liu, Annlia Paganini-Hill, Mark J. Fisher

Pharmacy Faculty Articles and Research

PURPOSE: The first genomewide association study indicated that variations in the phosphodiesterase 4D (PDE4D) gene confer risk for ischemic stroke. However, inconsistencies among the studies designed to replicate the findings indicated the need for further investigation to elucidate the role of the PDE4 pathway in stroke pathogenesis. Hence, we studied the effect of global inhibition of the PDE4 pathway in two rat experimental stroke models, using the PDE4 inhibitor rolipram. Further, the specific role of the PDE4D isoform in ischemic stroke pathogenesis was studied using PDE4D knockout rats in experimental stroke. METHODS: Rats were subjected to either the …

The Role Of Ape/Ref-1 In Hepatocellular Carcinoma Progression, Zhen Yang, Sun Yang, Bobbye J. Misner, Feng Liu-Smith, Frank L. Meyskens

Pharmacy Faculty Articles and Research

Hepatocellular carcinoma (HCC) is responsible for a third of the estimated cancer-caused deaths worldwide. To deeply understand the mechanisms controlling HCC progression is of primary importance to develop new approaches for treatment. Apurinic/apyrimidinic endonuclease-1/redox effector factor 1 (APE/Ref-1) has been uncovered elevated in various types of cancer, including HCC. Additionally, HCC progression is always correlated with elevated copper (Cu). Our previous data demonstrated that Cu treatment initiated APE/Ref-1 expression and its downstream targets. Therefore, we hypothesized that APE/Ref-1 may be involved in HCC progression through mediating the effect of Cu to its signaling cascades. Following different treatments, human HCC cell …

Brief Intervention For Truant Youth Sexual Risk Behavior And Marijuana Use, Richard Dembo, Rhissa Briones-Robinson, Kimberly Barrett, Rocio Ungaro, Ken C. Winters, Steven Belenko, Lora M. Karas, Laura Gulledge, Jennifer Wareham

Faculty Publications

Substance use and sexual risk behaviors are common among adolescents, but research has focused attention on alcohol use. Much less is known about the relationship of marijuana use and sexual risk behavior among high-risk, especially truant, youths. We report interim findings from a NIDA-funded experimental, brief intervention (BI) study involving truant youths and their parents/guardians. Longitudinal data were analyzed to study (1) the relationships between the youths' marijuana use and sexual risk behavior and (2) the effects of a substance use BI on their marijuana use and sexual risk behavior. A growth model analysis for parallel processes was conducted to …

Social Networks Of Intimate Partner Violence Perpetrators, Wendy Elaine Viola

Dissertations and Theses

Empirical research in the areas of substance abuse (Beattie & Longabaugh, 1997; Beattie & Longabaugh, 1999; Falkin & Strauss, 2002; Gordon & Zrull, 1991; Humphreys & Noke, 1997; Mohr et al., 2001; Zywiak, Longabaugh & Wirtz, 2002) and general antisocial behavior (Browning, 2002; Capaldi, Dishion, Stoolmiller & Yoerger, 2001; Dishion, Patterson & Griesler, 1994) and a theoretical model of sexual assault perpetration (DeKeseredy & Schwartz, 1993; DeKeseredy, 1990a; DeKeseredy, 1988; Schwartz & DeKeseredy, 1997) highlight the role of peer groups' attitudes and behaviors in shaping those of their members.

Understanding Male Nursing Student Perceptions Of The Influence Of Gender: A Qualitative Case Study Approach Of Students, Faculty, And Administration In A Pacific Northwest Nursing Program, Jennifer Anne Anderson

Dissertations and Theses

In contemporary American society, the nursing profession is predominantly made up of white women. Currently, males make up only 6.8 percent of the three million nursing professionals in the U.S. and they are considered gender minorities within the nursing profession and within nursing education. As gender minorities, male students are identified as experiencing nursing programs and the practice of nursing differently than their female counterparts. The purpose of this single instrumental, within site case study was to explore the learning environment for male nursing students and to investigate the nature of the interactions between nursing faculty and male undergraduate students …

Racism, Heterosexism, Depression, And Hiv Risk Behaviors Of Native Men Who Have Sex With Men: Findings From The Honor Project, Matthew Alan Town

Dissertations and Theses

Racial minority men who have sex with men (MSM) experience greater levels of discrimination and higher rates of HIV infection. However, little is known about the associations between racial and heterosexist discrimination and HIV risk behavior. Further, little is known about the mechanisms of the association between racial and heterosexist discrimination and HIV risk behavior. There is some evidence to suggest that depression may be a mechanism that mediates the relationship between racial and heterosexist discrimination and HIV risk behavior. Thus, one purpose of this study was to investigate the extent to which discrimination based on both race and sexual …

The Influence Of Race/Ethnicity And Place Of Service On Breast Reconstruction For Medicare Beneficiaries With Mastectomy, Tracy Onega, Julie Weiss, Karla Kerlikowske, Karen Wernli

Dartmouth Scholarship

Racial disparities in breast reconstruction for breast cancer are documented. Place of service has contributed to disparities in cancer care; but the interaction of race/ethnicity and place of service has not been explicitly examined. We examined whether place of service modified the effect of race/ethnicity on receipt of reconstruction. We included women with a mastectomy for incident breast cancer in SEER-Medicare from 2005-2009. Using Medicare claims, we determined breast reconstruction within 6 months. Facility characteristics included: rural/urban location, teaching status, NCI Cancer Center designation, cooperative oncology group membership, Disproportionate Share Hospital (DSH) status, and breast surgery volume. Using multivariable logistic …

Laurentian Great Lakes Phytoplankton And Their Water Quality Characteristics, Including A Diatom-Based Model For Paleoreconstruction Of Phosphorus, Euan D. Reavie, Adam J. Heathcote, Victoria L. Shaw Chraïbi

Department of Earth and Atmospheric Sciences: Faculty Publications

Recent shifts in water quality and food web characteristics driven by anthropogenic impacts on the Laurentian Great Lakes warranted an examination of pelagic primary producers as tracers of environmental change. The distributions of the 263 common phytoplankton taxa were related to water quality variables to determine taxon-specific responses that may be useful in indicator models. A detailed checklist of taxa and their environmental optima are provided. Multivariate analyses indicated a strong relationship between total phosphorus (TP) and patterns in the diatom assemblages across the Great Lakes. Of the 118 common diatom taxa, 90 (76%) had a directional response along the …

The Importance Of Family-Systems Theory In Masters-Level School School Counseling Curriculum: A Study Of Faculty Perceptions, Gwen Gold

USF Tampa Graduate Theses and Dissertations

This study examined the perceptions of Council for Accreditation of Counseling & Related Educational Programs (CACREP) master's-level school counseling program coordinators and faculty members about the importance and relevance of family systems theory and techniques coursework in their program curriculum. Family-systems theory coursework is lacking in two-thirds of those accredited programs, although mandated by their major accrediting body, CACREP. CACREP issued curriculum standards and guidelines to ensure proper training of school-counseling students and the American School Counselor Association--the foundation that expands the image and influence of professional school counselors through advocacy, leadership, collaboration, and systemic change--has issued guidelines for the …

Epistasis In Predator-Prey Relationships, Iuliia Inozemtseva, James P. Braselton

Mathematical Sciences: Faculty Publications

Epistasis is the interaction between two or more genes to control a single phenotype. We model epistasis of the prey in a two-locus two-allele problem in a basic predator-prey relationship. The resulting model allows us to examine both population sizes as well as genotypic and phenotypic frequencies. In the context of several numerical examples, we show that if epistasis results in an undesirable or desirable phenotype in the prey by making the particular genotype more or less susceptible to the predator or dangerous to the predator, elimination of undesirable phenotypes and then genotypes occurs.
