Growth Of Extensional Faults And Folds During Deposition Of An Evaporite-Dominated Half-Graben Basin; The Carboniferous Billefjorden Trough, Svalbard, Alvar Braathen, Karoline Bælum, Harmon Maher Jr., Simon J. Buckley Jan 2012

Growth Of Extensional Faults And Folds During Deposition Of An Evaporite-Dominated Half-Graben Basin; The Carboniferous Billefjorden Trough, Svalbard, Alvar Braathen, Karoline Bælum, Harmon Maher Jr., Simon J. Buckley

Geography and Geology Faculty Publications

Normal-sense movements along two major strands of the Billefjorden Fault Zone controlled sedimentation in the Carboniferous Billefjorden Trough. The Billefjorden Trough is a more than 2000 meters thick, west-dipping half-graben basin where accommodation was provided by combinations of extensional faulting and folding throughout the basin history. Whereas previous workers have interpreted several of these folds as due to Tertiary contraction, we argue that they developed during rifting, as extensional forced folds in the style described by other workers from rifts such as the Gulf of Suez. The present basin geometry indicates that accommodation was facilitated by a combination of fault …


Talking The Talk And Walking The Walk: Do A Federal Agency's Women-Centered Services Match A Women-Centered Organizational Culture?, Sally Anne Mcshane Jan 2012

Talking The Talk And Walking The Walk: Do A Federal Agency's Women-Centered Services Match A Women-Centered Organizational Culture?, Sally Anne Mcshane

All Graduate Theses, Dissertations, and Other Capstone Projects

Federal government agencies that provide services for women would presumably have an internal women-friendly organizational culture. In this study, organizational culture is measured by financial benefits - annual salary and federal General Schedule grade - provided to women. Regression analyses were used to examine whether gender, grade, and type of agency have an effect on salary and grade. Also bonuses to women are examined, as well as whether men or women are the heads of individual agencies or umbrella departments. Women were awarded fewer bonuses and lesser amounts as compared to men. Also women often are leaders of individual women-centered …

Great Plains Soils May Be C Sinks, David E. Clay, Gregg C. Carlson, Sharon A. Clay, James Stone, Kurtis Reitsma, Ronald Gelderman

Agronomy, Horticulture and Plant Science Faculty Publications

Numerous studies with wide-ranging results have been conducted to resolve if Great Plains soils are a C source or sink. The authors addressed the source/sink question by examining the results from producer soil samples and production surveys that were analyzed and archived by the South Dakota Soil Testing Laboratory. Results showed that between 1985 and 2010, soil organic C content increased at a rate of 326 lb C/A/year, for a total increase of 24%. The increase was attributed to planting better adapted varieties and using better management practices that on average increased corn grain yields 2.29 bu/A/year. Higher soil organic …

Haptics-Augmented Training Software For Undergraduate Engineering Mechanics, Ernur Karadogan, Robert L. Williams, David R. Moore, Tian Luo

STEMPS Faculty Publications

This paper presents the development efforts for a set of software activities and tutorials to augment teaching and learning in standard required undergraduate engineering mechanics courses. Using these software activities, students can change parameters, predict answers, compare outcomes, interact with animations, and feel the results. The overall system aims to increase teaching and learning effectiveness by rendering the concepts compelling, fun, and engaging. The problem with current examples and homework problems is that they are flat, static, boring, and non-engaging, which may lead to student attrition and a less than full grasp of fundamental principles. We implement integration of haptics …

‘If It Be Love Indeed, Tell Me How Much’: Elizabeth Taylor, Richard Burton And White Pleasure After Empire, Gloria Shin Jan 2012

‘If It Be Love Indeed, Tell Me How Much’: Elizabeth Taylor, Richard Burton And White Pleasure After Empire, Gloria Shin

Reconstruction: Studies in Contemporary Culture

In this paper, I use the iconicity of 1960s Elizabeth Taylor and Richard Burton to theorize the visualization and formation of an ecstatic postcolonial whiteness.

To begin with, I adapt Edward Said’s formulation of orientalism to discuss Elizabeth Taylor’s exotic turn and emergence as a white oriental that buttresses the production of her film Cleopatra (1963). Through archival research, I map out Taylor’s orientalism, in this case the malleability of her image to exoticization evidenced by her enthusiastic conversion to Judaism in 1959, her influence as “Cleopatra” to set style trends in women’s makeup, hair and fashion in the 1960s, …


Neuroinflammation In The Aging Down Syndrome Brain; Lessons From Alzheimer's Disease, Donna M. Wilcock Jan 2012

Neuroinflammation In The Aging Down Syndrome Brain; Lessons From Alzheimer's Disease, Donna M. Wilcock

Physiology Faculty Publications

Down syndrome (DS) is the most genetic cause of mental retardation and is caused by the triplication of chromosome 21. In addition to the disabilities caused early in life, DS is also noted as causing Alzheimer's-disease-like pathological changes in the brain, leading to 50-70% of DS patients showing dementia by 60-70 years of age. Inflammation is a complex process that has a key role to play in the pathogenesis of Alzheimer's disease. There is relatively little understood about inflammation in the DS brain and how the genetics of DS may alter this inflammatory response and change the course of disease …


A Changing Perspective On The Role Of Neuroinflammation In Alzheimer's Disease, Donna M. Wilcock Jan 2012

A Changing Perspective On The Role Of Neuroinflammation In Alzheimer's Disease, Donna M. Wilcock

Physiology Faculty Publications

Alzheimer's disease (AD) is a complex, neurodegenerative disorder characterized by the presence of amyloid plaques and neurofibrillary tangles in the brain. Glial cells, particularly microglial cells, react to the presence of the amyloid plaques and neurofibrillary tangles producing an inflammatory response. While once considered immunologically privileged due to the blood-brain barrier, it is now understood that the glial cells of the brain are capable of complex inflammatory responses. This paper will discuss the published literature regarding the diverse roles of neuroinflammation in the modulation of AD pathologies. These data will then be related to the well-characterized macrophage phenotypes. The conclusion …


"Human Babesiosis": An Emerging Transfusion Dilemma, Helieh S. Oz, Karin N. Westlund Jan 2012

"Human Babesiosis": An Emerging Transfusion Dilemma, Helieh S. Oz, Karin N. Westlund

Physiology Faculty Publications

Babesiosis, a common disease of animals, can infect humans via vector "tick bite", particularly in endemic areas. The recent reports of fatal cases in Hepatitis C and postliver transplant patients resulting from transfusion of contaminated blood should alert the medical profession regarding this emerging dilemma in endemic as well as nonendemic areas and the need for accurate blood screening for transfusion. Here, we illustrate different stages of the parasite lifecycle, progression of babesiosis in animal model, some aspects of pathologic outcomes, ongoing therapeutic modalities, and a feasible Acridine Orange fluorescent methodology for the diagnostic evaluation of blood samples.

Pegylated Arginine Deiminase Downregulates Colitis In Murine Models, Helieh S. Oz, Jian Zhong, Willem J. S. De Villiers Jan 2012

Pegylated Arginine Deiminase Downregulates Colitis In Murine Models, Helieh S. Oz, Jian Zhong, Willem J. S. De Villiers

Physiology Faculty Publications

Arginine deiminase (ADI), an arginine-metabolizing enzyme involved in cell signaling, is dysregulated in multiple inflammatory diseases and cancers. We hypothesized that pegylated ADI (ADI-PEG) provide protection against colitis.

METHODS: Dextran sodium sulfate colitis was induced in IL-10-deficient and BALB/c (WT) mice. ADI-PEG was administered i.p., and inflammatory mediators and pathology were evaluated.

RESULTS: Acute colitis in mice was manifested by increases in inflammatory biomarkers, such as serum amyloid A (SAA, P < 0.001), IL-12 p40, and disease index (3-Fold). In contrast, ADI-PEG significantly decreased clinical disease index, SAA levels, and inflammatory cytokines in blood as well as in colonic explants. Animals developed moderate (2.2 ± 0.3 WT) to severe (3.6 ± 0.5 IL-10 deficient) colonic pathology; and ADI-PEG treatment significantly improved the severity of colitis (P < 0.05). Marked infiltration of CD68+ macrophages and iNOS expression were detected in colonic submucosa in colitic animals but not detected in ADI-PEG-treated animals.

CONCLUSION: ADI-PEG attenuated inflammatory responses by suppression of macrophage infiltration and iNOS expression in colitic animals. ADI-PEG can serve as a potential therapeutic value in IBD.


Net Ecosystem Production (Nep) Of The Great Plains, United States, Daniel Howard, Tagir Gilmanov, Yingxin Gu, Bruce Wylie, Li Zhang Jan 2012

Net Ecosystem Production (Nep) Of The Great Plains, United States, Daniel Howard, Tagir Gilmanov, Yingxin Gu, Bruce Wylie, Li Zhang

Natural Resource Management Faculty Publications

Gross primary production (GPP) and ecosystem respiration (Re) are the fundamental environmental characteristics that promote carbon exchanges with the atmosphere (Chapin and others, 2009), although other exchanges of carbon, such as direct oxidation (Lovett and others, 2006), can modify net ecosystem production (NEP). The accumulation of carbon in terrestrial ecosystems results in systems in which soil organic matter (SOM) carbon often exceeds biomass carbon (Post and Kwon, 2000). This SOM pool exists at a steady state between GPP and Re in ecosystems unless drivers change or the ecosystem endures environmental perturbations (for example, climatic). As indicated by Wilhelm and others …

Procedurally Generating Everything, Micah Caunter Jan 2012

Procedurally Generating Everything, Micah Caunter

Senior Independent Study Theses

This paper investigates using Perlin Noise in a three-dimensional environment. Perlin Noise has been previously used to simulate clouds, marble, wood, and other natural phenomena as well as to model virtual landscapes. The simulation created for the I.S. procedurally generates both static and animated textures and models virtual landscapes to create a virtual world. In order to keep up with the rapidly advancing graphics industry, the OpenGL API is utilized to generate the textures in real-time and to display the final product.


Lecture Capture Technology : Does It Make A Difference On College Student Achievement?, Debra S. Bruxvoort Jan 2012

Lecture Capture Technology : Does It Make A Difference On College Student Achievement?, Debra S. Bruxvoort

Graduate Research Papers

Lecture capture technology allows professors to record live lectures for students to view after class. That same technology can be used to pre-record lectures for student viewing before class so that the class session can be used for other learning activities. This is referred to as the flipped classroom model. Most previous studies on the effect of lecture capture technology have focused on student perceptions and self-reported data and took place at large universities. This quantitative study collected multiple measures in an experimental design to compare the academic performance of 54 undergraduate students in three sections of the same course …

Stratigraphy And Paleoenvironments Of The Soeginina Beds (Paadla Formation, Lower Ludlow, Upper Silurian) On Saaremaa Island, Estonia, Richa N. Ekka

Senior Independent Study Theses

The Soeginina Beds in the Paadla Formation on the island of Saaremaa, western Estonia, are a lower Ludlow (Upper Silurian) sequence of dolostones, marls, and stromatolites. They represent rocks just above the Wenlock/Ludlow boundary, which is distinguished by a major disconformity that can be correlated to a regional regression on the paleocontinent of Baltica. The depositional environments of the Soeginina Beds include a shelfal environment, restricted shallow marine setting, intertidal mudflat and finally a hypersaline supratidal setting. The evidence includes halite crystal molds, oscillation ripples, eurypterid fragments, stromatolites, ostracods, gastropods, Chondrites trace fossils, intraclasts and oncoids. Nautiloid conchs are common, …

The Relationship Between Insufficient Sleep And Self-Rated Health In A Nationally Representative Sample, Sarah Dee Geiger, Charumathi Sabanayagam, Anoop Shankar Jan 2012

The Relationship Between Insufficient Sleep And Self-Rated Health In A Nationally Representative Sample, Sarah Dee Geiger, Charumathi Sabanayagam, Anoop Shankar

Faculty Articles, Papers, and Other Scholarship

Reduced sleep has been found to be associated with increased risk of diabetes mellitus, hypertension, cardiovascular disease (CVD), and mortality. Self-rated health (SRH) has been shown to be a predictor of CVD and mortality. However, study of the association between insufficient sleep and SRH is limited. We examined participants >18 years of age (n = 377, 160) from a representative, cross-sectional survey (2008 BRFSS). Self-reported insufficient sleep in the previous 30 days was categorized into six groups. The outcome was poor SRH. We calculated odds ratios ((OR) (95% confidence interval (CI)) of increasing categories of insufficient rest/sleep, taking zero days …


Features For Non-Targeted Cross-Sample Analysis With Comprehensive Two-Dimensional Chromatography, Stephen E. Reichenbach, Xue Tian, Chiara Cordero, Qingping Tao Jan 2012

Features For Non-Targeted Cross-Sample Analysis With Comprehensive Two-Dimensional Chromatography, Stephen E. Reichenbach, Xue Tian, Chiara Cordero, Qingping Tao

School of Computing: Faculty Publications

This review surveys different approaches for generating features from comprehensive two-dimensional chromatography for non-targeted cross-sample analysis. The goal of non-targeted cross-sample analysis is to discover relevant chemical characteristics (such as compositional similarities or differences) from multiple samples. In non-targeted analysis, the relevant characteristics are unknown, so individual features for all chemical constituents should be analyzed, not just those for targeted or selected analytes. Cross-sample analysis requires matching the corresponding features that characterize each constituent across multiple samples so that relevant characteristics or patterns can be recognized. Non-targeted, cross-sample analysis requires generating and matching all features across all samples. Applications of …
