Evaluating The Impact Of An Exotic Plant Invasion On Rodent Community Richness And Abundance, Trinity N. Smith, Eric M. Gese, Bryan M. Kluever

United States Department of Agriculture Wildlife Services: Staff Publications

Cheatgrass (Bromus tectorum), Russian thistle (Salsola kali), and tall tumblemustard (Sisymbrium altissimum) are nonnative plants widely distributed throughout the desert and shrubsteppe communities of the western United States. The impact of these invaders on plant community structure, form, and function has been well documented, but investigations determining the impacts of this cumulative invasion on terrestrial vertebrates have not been undertaken. Our objective was to assess community-level rodent responses to changes in plant community features, with an emphasis on dominance of invasive plant species. We sampled rodent and plant communities in the Great Basin Desert …

Efficacy Of An Acoustic Hailing Device As An Avian Dispersal Tool, Peter E. Schlichting, Amanda E. Holland, James C. Beasley, Albert L. Bryan, Robert A. Kennamer, Travis L. Devault, Bradley F. Blackwell, Olin E. Rhodes Jr.

United States Department of Agriculture Wildlife Services: Staff Publications

Bird strikes are a major safety and financial concern for modern aviation. Audible stimuli are common bird dispersal techniques, but their effectiveness is limited by the saliency and relevance of the stimulus. Furthermore, high ambient sound levels present at airfields might require that effective audible stimuli rely more on total volume (i.e., exceeding physiological tolerances) than ecological relevance. Acoustic hailing devices (AHD) are capable of sound output with a narrow beamwidth and at volumes high enough to cause physical discomfort at long distances. We tested the effectiveness of anAHD as a dispersal tool on freeranging birds recognized as hazardous to …

Survival And Habitat Selection Of Canada Geese During Autumn And Winter In Metropolitan Chicago, Usa, Brett E. Dorak, Michael P. Ward, Michael W. Eichholz, Brian E. Washburn, Timothy P. Lyons, Heath M. Hagy

United States Department of Agriculture Wildlife Services: Staff Publications

Winter distribution and resource use of animals is driven by myriad interacting biotic and abiotic factors. Urban areas provide sanctuaries from hunting for game animals and may have thermal benefits during winter through reduced thermoregulatory costs. We deployed cellular GPS transmitters affixed to neck collars of 41 Canada Geese (Branta canadensis) in the Greater Chicago Metropolitan Area (GCMA) of northeastern Illinois, USA, to determine habitat selection and survival during autumn and winter. Canada Geese selected green spaces (59.8%) in greater proportion than available (14%), but they also regularly used industrial urban habitats such as rooftops and rail yards …

Wetland Bird Abundance And Safety Implications For Military Aircraft Operations, Kent Andersson, Craig A. Davis, Bradley F. Blackwell, Jason R. Heinen

United States Department of Agriculture Wildlife Services: Staff Publications

Wetlands with associated avifauna can pose a substantial hazard to aviation safety, potentially increasing bird–aircraft collision (strike) risk when located near air operations areas.We modeled year-round use by wetland avifauna of Drummond Flats Wildlife Management Area (Drummond Flats), a wetland complex located within 10 km of Vance Air Force Base (AFB), Enid, Oklahoma, USA. Our objectives were to 1) quantify seasonal avifauna abundances at Drummond Flats; 2) test a priori models reflecting use by bird species recognized as hazardous to aviation safety relative to environmental factors including flooded wetland habitat and vegetation cover; 3) use these models to predict maximal …

Participant Perspectives On Housing And Landlords In A Canadian Housing First Program, Timothy Macleod

Theses and Dissertations (Comprehensive)

Housing First (HF) is an evidence-based approach to housing and services for adults who are chronically homeless and have a psychiatric disability. Research has demonstrated that HF rapidly ends homelessness but less in known about how participants experience their housing environments and landlords. This study is a part of a larger Canadian randomized field trial of HF that included qualitative interviews with participants in five cities. The narratives of 127 participants randomized to HF (n=82) or Treatment as Usual (TAU, n=45) were collected with regard to their perceptions of housing and landlords. Participant narratives were analyzed using thematic analysis and …

Performance Of Cormix Model For Point Source Contamination Simulations In Rivers Due To Oil Spills From Pipeline Failures, Joseph Gregory Heiden

Theses and Dissertations

This research focuses on a point-source oil contamination scenario for surface flow created by a pipeline failure. In this hypothetical scenario, a pipeline crossing two different river types (wide and regulated, and narrow, slightly meandering) will begin to leak and contaminant the rivers. CORMIX, a U.S. EPA supported mixing zone model, was used to model concentration of the near-field, starting from the source of the contaminant and throughout the region of interest. CORMIX takes the fundamental behaviors of an oil spill to provide an accurate and easy-to-use fate and transport model. The severity of the oil spill is categorized into …

An Intrinsic Characterization Of Bonnet Surfaces Based On A Closed Differential Ideal, Paul Bracken

School of Mathematical & Statistical Sciences Faculty Publications

The structure equations for a two-dimensional manifold are introduced and two results based on the Codazzi equations pertinent to the study of isometric surfaces are obtained from them. Important theorems pertaining to isometric surfaces are stated and a theorem due to Bonnet is obtained. A transformation for the connection forms is developed. It is proved that the angle of deformation must be harmonic, and that the differentials of many of the important variables generate a closed differential ideal. This implies that a coordinate system exists in which many of the variables satisfy particular ordinary differential equations, and these results can …

Fuel Consumption Model Generation, Emission Estimation And Life Cycle Cost Analysis, Ehtesam Rabbi Rabbi

Theses and Dissertations

There are a variety of transit bus sizes and types that are suitable for different types of cities, services, and operations. The size of a bus has a direct effect on the operating costs due to fuel consumption. Also, selecting bus size properly is very important for correct functioning and the quality and service level of public transportation. A decision on selecting bus size, fuel type and model year can only be made after considering the demand for each of the service routes on the system, fuel cost, and emission level. It is necessary to provide engineering resources to the …

Latin America In Theories Of Territorial Rights / América Latina En Las Teorías De Los Derechos Territoriales, Avery Kolers

Faculty and Staff Scholarship

“Who owns it?” is a surprisingly confusing question when applied to territory. Each word opens up puzzles: who can “own” territory? What is “ownership” in this context? How can it be justified in a way that could convince an outsider? These questions are particularly salient in the Latin American context, where multiple distinct kinds of land disputes converge. This paper canvasses two familiar approaches to these questions: the Kantian autochthony view, and the Lockean efficiency view. Neither view answers the question as to “who owns it” in all its complexity. The paper then defends an alternative approach grounded in recognition …

Revising The Body Esteem Scale With A U.S. College Student Sample: Evaluation, Validation, And Uses For The Bes-R, Katherine Frost, Stephen L. Franzoi, Debra L. Oswald, Stephanie A. Shields

Psychology Faculty Research and Publications

The Body Esteem Scale (BES; Franzoi and Shields 1984) has been a primary research tool for over 30 years, yet its factor structure has not been fully assessed since its creation, so a two-study design examined whether the BES needed revision. In Study 1, a series of principal components analyses (PCAs) was conducted using the BES responses of 798 undergraduate students, with results indicating that changes were necessary to improve the scale’s accuracy. In Study 2, 1237 undergraduate students evaluated each BES item, along with a select set of new body items, while also rating each item’s importance to their …

Dear John, You Are A Human Trafficker, Mary Graw Leary

Scholarly Articles

Human trafficking finally presents a crime that appropriately shifts the culpability from the abused to the abuser. As the heinous world of human trafficking is studied and more is understood about its inner workings, we can no longer conflate victimization with over-criminalization. The purpose of this paper is to shine light on the force and fraud that perpetuates the enslavement of victims who are sexually trafficked. Beginning with the Mann Act passed by Congress and up until more recently, the Trafficking Victims Protection Act, this paper traces the historical and societal shifts that are necessary to situate Sex Purchasers in …

The Mediating Effects Of Cortisol On The Relationship Between Conscientiousness And Judgments Of Learning, Katherine D. Miller

Graduate Theses/Dissertations

Cortisol assists in facilitating stress response. A peak in cortisol levels can be seen between 20 and 40 minutes after exposure to the stressful event. Judgments of learning (JOLs) are within the field of metacognition and are judgments individuals make about how well they feel they have acquired the target information. Many factors influence the accuracy of these judgments, including whether they are immediate or delayed. Conscientiousness is a characteristic of personality that is associated with responsibility and organization. Individuals high in conscientiousness are more likely to have positive health related outcomes. A relationship between conscientiousness and the appraisal of …

On The Origin Of Superoxide Dismutase: An Evolutionary Perspective Of Superoxide-Mediated Redox Signaling., Adam J. Case

Journal Articles: Cellular & Integrative Physiology

The field of free radical biology originated with the discovery of superoxide dismutase (SOD) in 1969. Over the last 5 decades, a plethora of research has been performed in species ranging from bacteria to mammals that has elucidated the molecular reaction, subcellular location, and specific isoforms of SOD. However, while humans have only begun to study this class of enzymes over the past 50 years, it has been estimated that these enzymes have existed for billions of years, and may be some of the original enzymes found in primitive life. As life evolved over this expanse of time, these enzymes …

The Antihypertensive Mthfr Gene Polymorphism Rs17367504-G Is A Possible Novel Protective Locus For Preeclampsia, Liv Cecilie V. Thomsen, Nina S. Mccarthy, Phillip E. Melton, Gemma Cadby, Rigmor Austgulen

School of Medicine Publications

Objective:

Preeclampsia is a complex heterogeneous disease commonly defined by new-onset hypertension and proteinuria in pregnancy. Women experiencing preeclampsia have increased risk for cardiovascular diseases (CVD) later in life. Preeclampsia and CVD share risk factors and pathophysiologic mechanisms, including dysregulated inflammation and raised blood pressure. Despite commonalities, little is known about the contribution of shared genes (pleiotropy) to these diseases. This study aimed to investigate whether genetic risk factors for hypertension or inflammation are pleiotropic by also being associated with preeclampsia.

Methods:

We genotyped 122 single nucleotide polymorphisms (SNPs) in women with preeclampsia (n = 1006) and nonpreeclamptic controls …

Anisotropic Character Of Low-Order Turbulent Flow Descriptions Through The Proper Orthogonal Decomposition, Nicholas Hamilton, Murat Tutkun, Raúl Bayoán Cal

Mechanical and Materials Engineering Faculty Publications and Presentations

Proper orthogonal decomposition (POD) is applied to distinct data sets in order to characterize the propagation of error arising from basis truncation in the description of turbulence. Experimental data from stereo particle image velocimetry measurements in a wind turbine array and direct numerical simulation data from a fully developed channel flow are used to illustrate dependence of the anisotropy tensor invariants as a function of POD modes used in low-order descriptions. In all cases, ensembles of snapshots illuminate a variety of anisotropic states of turbulence. In the near wake of a model wind turbine, the turbulence field reflects the periodic …

As both celebration and demonstration, the Mercury-Atlas 7 fluids experiment is revisited in light of the current understanding of large-length-scale capillary fluidics. Employing a modern numerical tool, a rich variety of experimental outcomes are discovered that were not observed during the flight experiment. Interestingly, experimental …

Serbian Jerusalem: Religious Nationalism, Globalization And The Invention Of A Holy Land In Europe's Periphery, 1985-2017, Vjekoslav Perica

Occasional Papers on Religion in Eastern Europe

According to beliefs of religious nationalism, a nation is a community of ancestors and descendants, dead and living, past and present. As such, it incorporates within its territory all past and present markers of nationhood, notably historic religious monuments as the physical evidence of the perennial existence of the religious and ethnic community that is, in the nationalist imagination, of the nation. Thus, the history of the shrines and monuments, as told in religious tales and preserved in the rituals, is the history of the nation. In many parts of the world, contesting claims to consecrated territories clash. The struggles …

Effects Of Nonaerated Circulation Water Velocity On Nutrient Release From Aquaculture Pond Sediments, Xiangju Cheng, Dantong Zhu, Xixi Wang, Deguang Yu, Jun Xie

Civil & Environmental Engineering Faculty Publications

Sustaining good water quality in aquaculture ponds is vital. Without an aerator, the dissolved oxygen in ponds comes primarily from mass transfer at the water-ambient atmosphere interface. As sediment can seriously affect water quality, this study used indoor experiments to examine the nutrient (nitrogen and phosphorus) release mechanisms and fluxes from sediment in aquaculture ponds with moving water but no aeration. The results showed that the ammonia nitrogen (NH₃-N) concentration in the overlying water was inversely proportional to flow velocity and that a higher flow velocity tended to result in a lower concentration in the overlying water, a …

Civil & Environmental Engineering Faculty Publications

The information on transpiration is vital for sustaining fragile ecosystem in arid/semiarid environment, including the Horqin Sandy Land (HSL) located in northeast China. However, such information is scarce in existing literature. The objectives of this study were to: (1) measure sap flow of selected individual stems of two sand-fixing plants, namely Salix gordejevii and Caragana microphylla, in HSL; and (2) upscale the measured stem-level sap flow for estimating the community-level transpiration. The measurements were done from 1 May to 30 September 2015 (i.e., during the growing season). The upscaling function was developed to have one dependent variable, namely sap …

Water–Soil–Vegetation Dynamic Interactions In Changing Climate, Xixi Wang, Xuefeng Chu, Tingxi Liu, Xiangju Cheng, Rich Whittecar

Civil & Environmental Engineering Faculty Publications

Previous studies of land degradation, topsoil erosion, and hydrologic alteration typically focus on these subjects individually, missing important interrelationships among these important aspects of the Earth's system. However, an understanding of water–soil–vegetation dynamic interactions is needed to develop practical and effective solutions to sustain the globe's eco-environment and grassland agriculture, which depends on grasses, legumes, and other fodder or soil-building crops. This special issue is intended to be a platform for a discussion of the relevant scientific findings based on experimental and/or modeling studies. Its 12 peer-reviewed articles present data, novel analysis/modeling approaches, and convincing results of water–soil–vegetation interactions under …
