Geospatial And Statistical Foundations For Streamflow Synthesis In West Virginia, Annie J. Morris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Streamflow values must be synthesized for locations where flow measurement stations, in applications such as the West Virginia SWAP program, are lacking or where only intermittent measurements are available (West Virginia Department of Health and Human Resources, 1999). This research describes an effort to improve upon the current synthetic streamflow model by incorporating geomorphic, geologic, and hydrogeologic measurements. Principal components analysis (PCA) was used to derive a set of master variables that characterize stream flow in West Virginia based on historical data from 29 watersheds. The relationships between variables affecting stream flow were also analyzed using cluster and correlation analysis …

Chemical And Physical Properties Of Acid Mine Drainage Floc, Catherine M. Bohan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid mine drainage is a serious environmental concern in many regions worldwide, but especially in coal and metal mining regions. These acid drainages are often treated with chemicals to raise the pH of the water and to cause neutralization and precipitation of metals. As neutralization occurs, a looser gelatinous material called "floc" is produced. The effects of neutralizing chemical, pH, sulfate to iron molar ratio, and solids concentration on floc settling properties were determined in synthetic acid mine drainage. Sulfate was the important factor affecting floc physicochemical properties, increasing settling times from 25-125% and decreasing settling rates from 24-63%. Neutralization …

Who's The Safer Sex? Testing Barbara Burrell's Theory Of Campaign Contributions In Arkansas State Legislative Elections, Emily Adair Neff-Sharum

Graduate Theses and Dissertations

At the very heart of American politics and government is democracy. Debates abound about the nature of American democracy, and especially ways to improve symbolic representation, substantive representation and/or participation by groups typically considered in the political minority (Moss-Kanter 1977; Pipert-High and Comer 1988; Saint-Germaine 1989; Seldon 1997; Thomas 1997). One focus of this literature is on the outputs of bureaucratic agencies or legislative agendas. If advocates of representative democracy hope to create legislatures on both the state and the national levels that contain an adequate presence of female representatives in order to fully represent women, they must begin with …

Brain Potentials Elicited By Prose-Embedded Linguistic Anomalies, Mark D. Allen, Kayo Inoue, Judith Mclaughlin, Lee Osterhout

Faculty Publications

Linguistic theories distinguish between syntax (sentence form) and semantics (sentence meaning). Correspondingly, recent studies have shown that syntactic and semantic anomalies elicit distinct changes in the event-related brain potential (ERP). However, these results have been obtained with highly artificial methodologies and have not yet been generalized to more natural reading conditions. Here, we recorded ERPs while subjects read a naturalistic prose passage. The subjects either read for comprehension with no other task being assigned or read for comprehension and made acceptability judgments after each sentence. Consistent with prior work and regardless of the subjects’ assigned task, syntactic anomalies elicited a …

Roles And Regulation Of Nf-Κb In Platelet-Derived Growth Factor Transformed Cells, Takeshi Shimamura

Dissertations

Platelet-derived growth factor (PDGF) is overexpressed in various cancer cells and the overexpression may be correlated with the prognosis of several types of cancers. Binding of PDGF to its receptors induces receptor dimerization and subsequent autophosphorylation of tyrosine residues in the receptor’s cytoplasmic domains. The phosphorylated tyrosine residues interact with the secondary signaling molecules to initiate signaling cascades that trigger cellular changes by affecting downstream effectors. In our recent publication, we have shown that a NF-κB mediates the transformation of mouse fibroblast cells overexpressing PDGF B chain. Though there is a significant correlation between PDGF stimulation and NF-κB activity, it …

Growth Equilibrium Modeling Of Urban Sprawl On Agricultural Lands In West Virginia, Yohannes G. Hailu

Graduate Theses, Dissertations, and Problem Reports (ETD)

With dynamic economic and social changes, increasing pressure is exerted on natural resources management. Agricultural land resources particularly face growing pressure of conversion to non-agricultural uses from population and development demands for land. The continual conversion of agricultural land may have implications in terms of the loss of prime farmland, irreversible landscape changes, deteriorating environmental quality, and interference with rural lifestyles. This study models urban sprawl on agricultural land in a growth equilibrium modeling approach where the population-employment simultaneous equations system is estimated using two-stages-least-squares while changes in agricultural land is estimated using OLS on West Virginia data. Results of …

Impact Of Early Childhood Perceptions And Experiences On Oral Health Practices In Later Life, Johnna Marie Guzzi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Older adults are at a higher risk for numerous oral and systemic diseases. Oral conditions experienced by the elderly are believed to be cumulative. The purpose of this study was to determine if a relationship exists between early childhood dental care practices/experiences and perceived oral health needs of persons 60 years of age and older who are participants of three West Virginia facilities for the elderly (N = 90). Individuals were interviewed utilizing a two-part 21-item survey. Data analyses, including analysis of variance and tests of chi square, were conducted using the JMP program. Although individuals felt dental health was …

Examining The Effects Of Conducting Behavior-Based Safety Observations, Joseph R. Sasson

Masters Theses

Eleven computer terminal operators participated in a series of interventions aimed at increasing safe ergonomic performance. All participants received ergonomics training and performance feedback, and approximately one half of the participants conducted observations for safe behavior. Conducting observations of safety-related behavior is a critical component of the Behavior-Based Safety (BBS) process, yet few researchers have studied the effects of conducting observations on the behavior of the observer. This study sought to examine the effects of conducting BBS observations on the safe performance of the observer in an applied setting. A multiple baseline across participants design was used to assess the …

Examining The Effects Of Individualized Computer Work Station Adjustments And Performance Management On Safe Behavior, Kathryn Culig

Masters Theses

The first purpose of this study was to examine the effects of office ergonomic assessments and resulting computer workstation adjustments on safe behavior. The adjustments were designed to reduce or eliminate barriers to performing safely, thus creating an environment that would allow participants to assume safe behaviors. The second purpose of the study was to examine the effects of a performance management (PM) package, including ergonomic information, graphic feedback, and praise, which targeted those behaviors that did not substantially change as a result of the workstation adjustments. A multiple baseline design across participants was used to assess the effects of …

High Oblique Photographic Assessment Of Lakeshore Residential Landscapes In Southwest Michigan, John E. Truchan

Masters Theses

In Southwest Michigan, a growing number of residential developments are evident as residences line nearly the entire shoreline of many inland lakes. This may cause a potential change to the lakeshore vegetation and water quality of the lake, but no data have been collected to determine shoreline conditions at present nor as baseline reference for estimation effects of the continuing trend, nor for planning models for future development.

A physical survey was conducted in order to determine what residential landscape characteristics currently exist at selected lakes in Barry and Kalamazoo counties, Michigan. The data from the physical survey were summarized …

Management Commitment To Construction Safety, Areen M. Shaar

Masters Theses

The objective of all businesses including construction is to make money and to be profitable. The costs resulting from personal injuries and equipment damage, combined with the associated financial impact resulting from schedule disruptions, insurance hikes, and workers compensation can definitely impact the profitability of any construction operation. Most times those costs can be minimized or avoided by giving safety more attention on construction job sites.

The main purpose of this research is to determine the correlation between management commitment to safety and its impacts on the frequency of injuries and illnesses. To achieve this, a survey was methodically developed …

Practical Evaluation Of Psychotropic Medication, Lynne E. Turner

Masters Theses

Surveys indicate that 25-40% of students with mental retardation or other developmental disabilities receive one or more psychotropic medications, however, almost nothing is known concerning how the effects of the medications are monitored. Parents/guardians and teachers were interviewed to ascertain information regarding current monitoring procedures in the home and in the school setting. Additionally information was gathered to ascertain their knowledge regarding: 1) the reason for which their students were prescribed psychotropic medications; 2) the behavioral domains that those medications are intended to affect, 3) the current status of those behavioral domains, and 4) consumers' satisfaction with the pharmacological intervention. …

Bioorganic Studies In Aids: Synthetic Antifungals Against Pneumocystis Carinii Based On The Multivalency Concept, Langu Peng, Cunxiang Chen, Christian R. Gonzalez, Valeria Balogh-Nair

Publications and Research

We report the syntheses of antifungals containing the novel pharmacophores: oxaziridines, sulfonyloxaziridines, nitrones and nitronyl nitroxides. We hypothesized that multiple copies of the pharmacophore per molecule might be a prerequisite to enhance efficacy against the opportunistic pathogen, Pneumocystis carinii. Therefore structural optimization of the leads was based on this new “multivalency” approach. All bisoxaziridines were inactive, but a trisoxaziridine caused ca. 50% reduction of the number of P. carinii tropozoites, compared to TMP-SMX, and a hexaoxaziridine at 1 µg/ml showed activity comparable to the currently used drug, TMP-SMX. Insertion of three units of the nitronyl nitroxide pharmacophore per molecule afforded …

The Cd154/Cd40 Interaction Required For Retrovirus-Induced Murine Immunodeficiency Syndrome Is Not Mediated By Upregulation Of The Cd80/Cd86 Costimulatory Molecules, Kathy A. Green, W. James Cook, Arlene H. Sharpe, William R. Green

Dartmouth Scholarship

C57BL/6 (B6) mice infected with LP-BM5 retroviruses develop disease, including an immunodeficiency similar to AIDS. This disease, murine AIDS (MAIDS), is inhibited by in vivo anti-CD154 monoclonal antibody treatment. The similar levels of insusceptibility of CD40^−/− and CD154^−/− B6 mice indicate that CD154/CD40 molecular interactions are required for MAIDS. CD4⁺ T and B cells, respectively, provide the CD154 and CD40 expression needed for MAIDS induction. Here, the required CD154/CD40 interaction is shown to be independent of CD80 and CD86 expression: CD80/CD86^−/− B6 mice develop MAIDS after LP-BM5 infection.

Analysis Of Longitudinal Marginal Structural Models , Jennifer F. Bryan, Zhuo Yu, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

In this article we construct and study estimators of the causal effect of a time-dependent treatment on survival in longitudinal studies. We employ a particular marginal structural model (MSM), and follow a general methodology for constructing estimating functions in censored data models. The inverse probability of treatment weighted (IPTW) estimator is used as an initial estimator and the corresponding treatment-orthogonalized, one-step estimator is consistent and asymptotically linear when the treatment mechanism is consistently estimated. We extend these methods to handle informative censoring. A simulation study demonstrates that the the treatment-orthogonalized, one-step estimator is superior to the IPTW estimator in terms …
