Intergenerational Communication About African American Women's Health: The Sharing Of Health Messages Between Diabetic Mothers And Their Non-Diabetic Adult Daughters, Angela F. Cooke-Jackson Jan 2006

Intergenerational Communication About African American Women's Health: The Sharing Of Health Messages Between Diabetic Mothers And Their Non-Diabetic Adult Daughters, Angela F. Cooke-Jackson

University of Kentucky Doctoral Dissertations

The prevalence of type II diabetes is high among African-American women but research that emphasizes black mothers and their adult daughters is rarely studied in social sciences or communication research. Though existing research addresses various domains of the mother-daughter relationship scant information addresses the significance of talk or the transmission of health information between African-American diabetic mothers and their non-diabetic adult daughters. For that reason, this dissertation investigates information sharing among a sample of African-American mothers with type II diabetes and their non-diabetic adult daughters.This study's two primary research objectives were to: 1. describe whether and how African-American type II …

Suspended Sediment And Pathogen Transport In Two Inner Bluegrass Karst Ground-Water Basins, Woodford County, Kentucky, Thomas M. Reed Jan 2006

Suspended Sediment And Pathogen Transport In Two Inner Bluegrass Karst Ground-Water Basins, Woodford County, Kentucky, Thomas M. Reed

University of Kentucky Master's Theses

Multiple parameters were monitored during an 18-month period in two karst groundwater basins in Woodford County, Kentucky, in order to assess the effects of land use on water quality. Blue Hole Spring drains a primarily urban area, whereas spring SP-2 drains an agricultural area. Water-quality parameters were monitored manually weekly or biweekly, as well as more frequently during storms. Discharge (Q), temperature (T), specific conductance (SC), and turbidity were continuously monitored and logged at 15-minute intervals. It is hypothesized that pathogen and sediment concentrations would be lower at SP-2 than at Blue Hole Spring due to differences in land use …

Shear-Wave Velocities And Derivative Mapping For The Upper Mississippi Embayment, David M. Vance

University of Kentucky Master's Theses

During the past two decades, University of Kentucky researchers have been acquiring seismic refraction/reflection data, as well as seismic downhole data, for characterizing the seismic velocity models of the soil/sediment overburden in the central United States. The dataset includes densely spaced measurements for urban microzonation studies and coarsely spaced measurements for regional assessments. The 519 measurements and their derivative products often were not in an organized electronic form, however, limiting their accessibility for use by other researchers. In order to make these data more accessible, this project constructed a database using the ArcGIS 9.1 software. The data have been formatted …


Citizens On Patrol: Community Policing And The Territorialization Of Public Space In Seattle, Washington, Marcia Rae England Jan 2006

Citizens On Patrol: Community Policing And The Territorialization Of Public Space In Seattle, Washington, Marcia Rae England

University of Kentucky Doctoral Dissertations

This dissertation shows how organizations, including local government and police, and residents within Seattle, Washingtons East Precinct define and police the contours of community, neighborhoods and public space. Under the rubric of public safety, these players create territorial geographies that seek to include only those who fit the narrowly conceived idea of a neighbor. Territoriality is exercised against the social Other in an attempt to build a cohesive community while at the same time excluding those who are seen as different or as non-conformant to acceptable behaviors in the neighborhood. This research provides a framework through which to examine how …


The Politics Of Garbage: Municipal Solid Waste In Oaxaca, Mexico, Sarah Anne Moore Jan 2006

The Politics Of Garbage: Municipal Solid Waste In Oaxaca, Mexico, Sarah Anne Moore

University of Kentucky Master's Theses

This dissertation analyzes the politics of garbage in Oaxaca, Mexico. In particular, it explores the tactics used by a marginalized colonia near the dump to affect waste management and local development. This colonia provokes garbage crises by blocking the metropolitan areas access to its dump. As a result, garbage builds up in the city and public officials are forced to negotiate with colonia residents. I argue that two prior processes are essential to the success of this strategy. First, the mid-sized city in southern Mexico implemented many new waste management practices during the latter half of the 20th century and …


A Political Ecology Of The Chipko Movement, Sya Kedzior Jan 2006

A Political Ecology Of The Chipko Movement, Sya Kedzior

University of Kentucky Master's Theses

The Indian Chipko movement is analyzed as a case study employing a geographically-informed political ecology approach. Political ecology as a framework for the study of environmental movements provides insight into the complex issues surrounding the structure of Indian society, with particular attention to its ecological and political dimensions. This framework, with its focus on social structure and ecology, is distinct from the more traditional approaches to the study of social movements, which tend to essentialize their purpose and membership, often by focusing on a single dimension of the movement and its context. Using Chipko as a case-study, the author demonstrates …


Design Of Partial Enclosures For Acoustical Applications, Amy Elizabeth Carter Jan 2006

Design Of Partial Enclosures For Acoustical Applications, Amy Elizabeth Carter

University of Kentucky Master's Theses

Enclosures are a very common way to reduce noise emissions from machinery. However, enclosures display complex acoustic behavior that is difficult to predict. The research presented in this thesis uses the boundary element method in order to better understand the acoustic behavior of a partial enclosure. Insertion loss was used as the performance measure and the effect of several design factors on the overall insertion loss was documented. Results indicate that the most important factors affecting enclosure performance are the opening size, amount of absorption, and the source-to-opening distance.


Characterization And Measurement Of Tension-Induced Longitudinal Wrinkles In Gossamer Membranes Using Photogrammetry, Sreeram Mangalampalli Jan 2006

Characterization And Measurement Of Tension-Induced Longitudinal Wrinkles In Gossamer Membranes Using Photogrammetry, Sreeram Mangalampalli

University of Kentucky Master's Theses

Gossamer membranes are large, ultra light weight, highly flexible thin films. They have been proposed for use as elements in systems such as solar sails and optical apertures, whose large areas require a low-mass material that can be launched in a compact package and then deployed to operational configuration upon reaching orbit. Many of the proposed applications require that the film possess a flat, wrinkle-free surface. Surface wrinkle configuration is determined, in part, by the method used to support the film. One configuration that has not been studied in detail involves the formation of vertical wrinkles oriented along the direction …

The Chemical Species Of Aluminum Influences Its Paracellular Flux Across And Uptake Into Caco-2 Cells, A Model Of Gastrointestinal Absorption, Yuzhao Zhou, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Aluminum (Al) can cause neurotoxicity, a low-turnover osteomalacia, and microcytic anemia. To test the null hypothesis that the chemical form (species) of Al does not influence its mechanism or rate of absorption from the gastrointestinal tract, Al flux across and uptake into Caco-2 cells was investigated. Caco-2 cells were grown on porous membranes mounted in vertical diffusion chambers or in 35-mm-diameter plastic cell culture dishes. When 8 mM 27Al was introduced as the ion, citrate, maltolate, fluoride, or hydroxide, the apical to basolateral apparent permeability (Papp) of Al correlated highly with the Papp of lucifer yellow …

Cpg Oligodeoxynucleotides Stimulate Cord Blood Mononuclear Cells To Produce Immunoglobulins., Cheri D Landers, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

CpG oligodeoxynucleotides (ODNs) stimulate adult B cells leading to cellular proliferation and immunoglobulin production. It is unknown if CpG-ODNs similarly stimulate neonatal human B cells. Neonates have immature immune responses and are poorly responsive to thymus independent antigens such as polysaccharides. We determined umbilical cord cells' response to CpG-ODNs. Adult and umbilical cord B cells produced similar amounts of IgM (adult 1371 +/- 352 vs. cord 1873 +/- 1084 ng/ml) in response to CpG-ODN stimulation. Although CpG-ODN was able to stimulate adult IgG and IgA production, cord cells produced less IgG (153 +/- 58 vs. 10 +/- 2.5 ng/ml) and …

Behavioral Science Faculty Publications

BACKGROUND: HIV Associated Dementia (HAD) is a common complication of human immunodeficiency virus (HIV) infection that erodes the quality of life for patients and burdens health care providers. Intravenous drug use is a major route of HIV transmission, and drug use is associated with increased HAD. Specific proteins released as a consequence of HIV infection (e.g., gp120, the HIV envelope protein and Tat, the nuclear transactivating protein) have been implicated in the pathogenesis of HAD. In primary cultures of human fetal brain tissue, subtoxic doses of gp120 and Tat are capable of interacting with a physiologically relevant dose of cocaine, …

Manganese Distribution Across The Blood-Brain Barrier. Iv. Evidence For Brain Influx Through Store-Operated Calcium Channels, Janelle S. Crossgrove, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Manganese (Mn) is a required co-factor for many ubiquitous enzymes; however, chronic Mn overexposure can cause manganism, a parkinsonian-like syndrome. Previous studies showed Mn influx into brain is carrier-mediated, though the putative carrier(s) were not established. Studies conducted with cultured bovine brain microvascular endothelial cells (bBMECs), which comprise the blood–brain barrier, revealed 54Mn (II) uptake positively correlated with pH, was temperature-dependent, and was sodium- and energy-independent. Brain 54Mn uptake correlated inversely with calcium (Ca) concentration, but 45Ca uptake was unaltered by high Mn concentration. Lanthanum (La), a non-selective inhibitor of several Ca channel types, as well as …


Evaluation Of Methods To Limit The Time Taken To Investigate Crash Sites, Jennifer R. Walton, Monica L. Barrett, Kenneth R. Agent Jun 2005

Evaluation Of Methods To Limit The Time Taken To Investigate Crash Sites, Jennifer R. Walton, Monica L. Barrett, Kenneth R. Agent

Kentucky Transportation Center Research Report

Highway crashes have significant direct and indirect costs associated with them. Substantial sources of indirect costs are the congestion and delays that result from lane blockages or road closures while the crash is being investigated and the site cleared. In many cases, vehicles could be moved and roadways reopened very quickly, but this does not occur because of the need (or perceived need) to conduct a detailed investigation of the crash scene. The objective of this study was to identify opportunities to reduce the time required to investigate and clear crash scenes. This project includes a review of state and …
