Intercalibraton In Chemical Oceanography-- Getting The Right Number, Gregory A. Cutter Jan 2013

Intercalibraton In Chemical Oceanography-- Getting The Right Number, Gregory A. Cutter

OES Faculty Publications

Intercalibration has a strict metrological definition, but in brief, it's an open sharing of methods and results between laboratories to achieve the most accurate data with the fewest random and systematic errors. In the field of chemical oceanography where concentrations of many constituents can be in the nano- to picomolar range, the salt water matrix can be difficult to analyze, and knowing the exact concentrations, or even chemical forms, of biologically required elements is essential, intercalibration is a very relevant and needed tool. Implementing it is not simple because errors can occur at any step in the process of taking …

Surface Production Fuels Deep Heterotrophic Respiration In Northern Peatlands, J. Elizabeth Corbett, David J. Burdige, Malak M. Tfaily, Angela R. Dial, William T. Cooper, Paul H. Glaser, Jeffrey P. Chanton Jan 2013

Surface Production Fuels Deep Heterotrophic Respiration In Northern Peatlands, J. Elizabeth Corbett, David J. Burdige, Malak M. Tfaily, Angela R. Dial, William T. Cooper, Paul H. Glaser, Jeffrey P. Chanton

OES Faculty Publications

Multiple analyses of dissolved organic carbon (DOC) from pore waters were conducted to define the processes that govern carbon balance in peatlands: (1) source, reactivity, and transport of DOC with respect to vegetation, peat, and age of carbon substrate, (2) reactivity of DOC with respect to molecular size, and (3) lability to photoxidation of surficial DOC. We found that surface organic production fuels heterotrophic respiration at depth in advection-dominated peatlands, especially in fens. Fen DOC was Δ14Cenriched relative to the surrounding fen peat, and fen respiration products were similar to this enriched DOC indicating that DOC was the …

Using Ammonium Pore Water Profiles To Assess Stoichiometry Of Deep Remineralization Processes In Methanogenic Continental Margin Sediments, David J. Burdige, Tomoko Komada Jan 2013

Using Ammonium Pore Water Profiles To Assess Stoichiometry Of Deep Remineralization Processes In Methanogenic Continental Margin Sediments, David J. Burdige, Tomoko Komada

OES Faculty Publications

In many continental margin Sediments, a deep reaction zone exists which is separated from remineralization processes near the sediment surface. Here, methane diffuses upward to a depth where it is oxidized by downwardly diffusing sulfate. However, the methane sources that drive this anaerobic oxidation of methane (AOM) in the sulfate-methane transition zone (SMT) may vary among sites. In particular, these sources can be thought of as either (i) "internal" sources from in situ methanogenesis (regardless of where it occurs in the sediment column) that are ultimately coupled to organic matter deposition and burial, or (ii) "external" sources such as hydrocarbon …

Psychology Faculty Research and Publications

Previous studies suggest that task-activated functional magnetic resonance imaging (fMRI) can predict future cognitive decline among healthy older adults. The present fMRI study examined the relative sensitivity of semantic memory (SM) versus episodic memory (EM) activation tasks for predicting cognitive decline. Seventy-eight cognitively intact elders underwent neuropsychological testing at entry and after an 18-month interval, with participants classified as cognitively “Stable” or “Declining” based on ≥1.0 SD decline in performance. Baseline fMRI scanning involved SM (famous name discrimination) and EM (name recognition) tasks. SM and EM fMRI activation, along with Apolipoprotein E (APOE) ε4 status, served as predictors of cognitive …

A Design For Inspiring Students With Near-Space Exploration, Jeremy Straub, Gail Ingwalson, Ronald Fevig Jan 2013

A Design For Inspiring Students With Near-Space Exploration, Jeremy Straub, Gail Ingwalson, Ronald Fevig

Journal of Aviation/Aerospace Education & Research

The prevalence of overseas success in engineering education represents a significant threat to the United States. Once the dominant force in advancing technology, the U.S. is seeing significant amounts of research and development work moving overseas. U.S. competitiveness and increased productivity requires demand for high-value-added products (Porter & Rivkin, 2012) such as those designed and developed by those with advanced training in science, technology, engineering and math (STEM) disciplines. The U.S. economy, thus, depends on the production of skilled scientists and engineers--not just to sustain American leadership in science, but to sustain its national economy.

Pharmaceuticals, Political Money, And Public Policy: A Theoretical And Empirical Agenda, Paul D. Jorgensen Jan 2013

Pharmaceuticals, Political Money, And Public Policy: A Theoretical And Empirical Agenda, Paul D. Jorgensen

Political Science Faculty Publications

Congress has consistently failed to solve some serious problems with the cost, effectiveness, and safety of pharmaceuticals. In part, this failure results from the pharmaceutical industry convincing legislators to define policy problems in ways that protect industry profits. By targeting campaign contributions to influential legislators and by providing them with selective information, the industry manages to displace the public’s voice in developing pharmaceutical policy.

Verification Of Information Flow Security In Cyber-Physical Systems, Rav Akella Jan 2013

Verification Of Information Flow Security In Cyber-Physical Systems, Rav Akella

Doctoral Dissertations

"With a growing number of real-world applications that are dependent on computation, securing the information space has become a challenge. The security of information in such applications is often jeopardized by software and hardware failures, intervention of human subjects such as attackers, incorrect design specification and implementation, other social and natural causes. Since these applications are very diverse, often cutting across disciplines a generic approach to detect and mitigate these issues is missing. This dissertation addresses the fundamental problem of verifying information security in a class of real world applications of computation, the Cyber-physical systems (CPSs). One of the motivations …

Capital Structure Deviation And Speed Of Adjustment, Tarun Mukherjee, Wei Wang Jan 2013

Capital Structure Deviation And Speed Of Adjustment, Tarun Mukherjee, Wei Wang

Business Faculty Publications

As a firm deviates from its target leverage, marginal bankruptcy costs change at a faster speed than marginal tax shield. This renders the speed of adjustment (SOA) of capital structure an increasing function of the starting deviation from the target. Adopting a bootstrapping-based estimation, we confirm the existence of such heterogeneity in SOA that is statistically significant and economically nontrivial. Typically, if Firm A is one standard deviation (about 17%) and Firm B is two standard deviations away from their leverage targets, then B’s SOA is 41% greater than that of A, and the half life of B’s leverage deviation …

The Effects Of Top Management Team External Ties And Board Composition On The Strategic Choice Of Late Movers, Jae Wook Yoo, Richard Reed Jan 2013

The Effects Of Top Management Team External Ties And Board Composition On The Strategic Choice Of Late Movers, Jae Wook Yoo, Richard Reed

Business Faculty Publications

Within the context of the monitoring and control function of the board, we extend previous work on the agency view of governance. We examine how the top managers' external ties and board composition directly and interactively influence the strategic choices of firms. Our results indicate that top managers with intra-industry knowledge and experience tend to adopt a resource-imitation strategy whereas those with knowledge and experience from other industries tend to adopt a resource-substitution strategy. The separation of CEO and board chairperson duties also affects strategy selection. In terms of interaction effects, we find that boards with a high ratio of …

Clinicians’ Reports Of The Impact Of The 2008 Financial Crisis On Mental Health Clients, Donna M. L. Heretick Jan 2013

Clinicians’ Reports Of The Impact Of The 2008 Financial Crisis On Mental Health Clients, Donna M. L. Heretick

Journal of Social, Behavioral, and Health Sciences

This study investigated the impact of the 2008 economic crisis on mental health clients. One hundred and three mental health providers (101 being psychologists) from California, Colorado, and Arizona completed an online survey. Following Lazarus’ stress theory, social identity theory, and the finances-shame model, several moderator variables were evaluated for impact of financial crisis: gender, age group, previous mental health, lifestyle threat, and sources for support. As predicted, male and female clients were generally described as equally stressed, but stress responses differed. Financial role responsibilities and previous mental health were noted as predictors of stress. Men—as well as clients earning …

Malnutrition In Sickle Cell Anemia: Implications For Infection, Growth And Maturation, Hyacinth I. Hyacinth, Oluwatoyosi A. Adekeye, Christopher S. Yilgwan Jan 2013

Malnutrition In Sickle Cell Anemia: Implications For Infection, Growth And Maturation, Hyacinth I. Hyacinth, Oluwatoyosi A. Adekeye, Christopher S. Yilgwan

Journal of Social, Behavioral, and Health Sciences

Sickle cell anemia (SCA) is a genetic disease that affects mostly individuals of African and/or Hispanic descent, with the majority of cases in sub-Saharan Africa. Individuals with this disease show slowed growth, delayed sexual maturity, and poor immunologic function. These complications could partly be explained by the state of undernutrition associated with the disease. Proposed mechanism of undernutrition include protein hypermetabolism, decreased dietary intake possibly from interleukin-6-related appetite suppression, increased cardiac energy demand/expenditure, and increased red cell turnover. All the above mechanisms manifest as increased resting energy expenditure. Nutritional intervention utilizing single or multiple nutrient supplementation has led to improved …

Self-Regulatory Skills For Controlled Eating Emanating From Newly Initiated Physical Activity, James J. Annesi Ph.D., Kandice Johnson Porter Jan 2013

Self-Regulatory Skills For Controlled Eating Emanating From Newly Initiated Physical Activity, James J. Annesi Ph.D., Kandice Johnson Porter

Journal of Social, Behavioral, and Health Sciences

The relationship of physical activity with weight loss may largely be due to its association with psychosocial factors. The goal of this research was to clarify such relationships using a field design lasting 24 weeks. In Study 1, change in self-regulation for controlled eating, but not energy expenditure, mediated the relationship between changes in physical activity and weight in formerly sedentary, severely obese adults (n = 174). In Study 2 (n = 148), the addition of a cognitive-behavioral nutrition treatment was associated with significantly greater improvement in self-regulation for eating. Physical activity-related self-regulation changes were related to those …

Molecular And Cellular Signatures Of Phytol Derivatives And The Small Intestinal Submucosa In Shaping Immune Responses To Staphylococcus Aureus, Chowdhury Roshni Roy

All-Inclusive List of Electronic Theses and Dissertations

Vaccines represent the most outstanding success story of modern medicine. In addition to pathogen-derived antigen(s), immune adjuvants are crucial for the development of efficacious new generation vaccines. Most modern vaccines are comprised of purified recombinant proteins, peptides or polysaccharides, which are weakly immunogenic. The incorporation of adjuvants in vaccine formulations not only enhances the immunogenicity of the antigen but also activates various innate and adaptive immune parameters. New-age adjuvants become particularly important in the development of vaccines against some challenging pathogens, such as Staphylococcus aureus, for which vaccines are not yet available or are inadequate. S. aureus has proven exceptionally …

Effects Of Low Oxygen On Cytokine And Nitric Oxide Release Of Activated N9 Microglia, Henry Owegi Jan 2013

Effects Of Low Oxygen On Cytokine And Nitric Oxide Release Of Activated N9 Microglia, Henry Owegi

All-Inclusive List of Electronic Theses and Dissertations

Every 16 seconds in the United States, a person suffers a traumatic brain injury (TBI). The major problems in TBI patients are increased intracranial pressure (ICP), and diffuse global ischemia, which leads to cerebral hypoxia. Cerebral ischemia occurs in 65% of patients due to microvascular spasms and brain swelling. Subsequently, cerebral ischemia is exacerbated by the inflammatory processes initiated by microglia. Although therapeutic ICP control has resulted in mortality reduction, cerebral ischemia is still the major contributor to poor neurological outcome. To address this problem, an oxygen-guided therapy was introduced and has resulted in a reduction of both mortality and …

Large-Scale Cloudscapes Using Noise, Mario Rosa Jan 2013

Large-Scale Cloudscapes Using Noise, Mario Rosa

Theses

Clouds have been of particular interest in computer graphics due to the challenge they present. Clouds are considered fuzzy objects, and need specialized algorithms to model and render realistically. Many techniques exist to model and render clouds that have had much success. This research will take existing techniques in cloud modeling and rendering and create a new technique combining those with noise. The idea is that noise can be used to model large-scale repeatable 3D cloudscapes and to be able to model such cloudscapes much more quickly than current techniques. This would be beneficial to developers of virtual universes that …

Effect Of Laser Ablation Depth In Otolith Life History Scans, Renée R. Hoover, Cynthia M. Jones Jan 2013

Effect Of Laser Ablation Depth In Otolith Life History Scans, Renée R. Hoover, Cynthia M. Jones

OES Faculty Publications

Life history scans of fish otoliths are bringing new insight into the structure, connectivity, and movement of fish populations. Data obtained from such scans, however, possess in-herent limitations that have not yet been fully addressed or understood. For example, several investigators have noted delays in otolith elemental uptake that do not appear to reflect habitat exposure. We hypothesized that the 3-dimensional structure of otoliths may produce sampling artifacts in the results obtained from laser ablation scans. To test this hypothesis, we sampled sagittal otoliths from juvenile Atlantic croaker Micropogonias undulatus with laser ablation inductively coupled plasma mass spectrometry to obtain …

The Association Of Blood Lipid Levels With The Epigenetic Regulation Of The Cpt1a Gene, Nikita Patel Jan 2013

The Association Of Blood Lipid Levels With The Epigenetic Regulation Of The Cpt1a Gene, Nikita Patel

Theses

DNA methylation directly influences gene expression. Previous studies showed that diet and genetics influence blood lipid levels. However, the association between DNA methylation and lipid levels is unknown. This study demonstrates a link between epigenetic variation and fasting blood lipid levels, particularly in triglycerides and VLDL-C. Approximately 470,000 CpGs were evaluated in 995 individuals to find epigenome-wide associations between methylation and lipid levels. Two CpGs sites located within theCPT1A gene showed strong association with fasting triglyceride and VLDC-C levels. Furthermore there was an inverse relationship between methylation levels at the most significant CpG within CPT1Aand its fold expression levels. CPT1 …
