Developing A Rabies Prevention Program Based On Rabies Exposure Data In Nebraska, Jill Oatman Dec 2020

Developing A Rabies Prevention Program Based On Rabies Exposure Data In Nebraska, Jill Oatman

Capstone Experience: Master of Public Health

Eighty-nine percent of Nebraska’s towns are considered rural, with populations of less than 3,000 people and with many towns having less than 1,000 residents. Rural areas consist of crop ground, livestock facilities and regions inhabited by wildlife. Nebraska has two large urban cities, Lincoln and Omaha. Animal and human health in these communities can be greatly impacted by infectious diseases that are transmitted between animals and humans, known as zoonotic diseases. One zoonotic disease of great concern is rabies. Zoonotic diseases not only impact the health of animals and humans, but the social well-being of communities and result in increased …

A Fast And Exact Motif Enumeration Algorithm For Dynamic Networks, Abbas Al-Thaedan Dec 2020

A Fast And Exact Motif Enumeration Algorithm For Dynamic Networks, Abbas Al-Thaedan

Theses and Dissertations

From social to biological networks, prior research in complex networks have demonstrated the importance of the frequency and distribution of different types of motifs to important network functions and properties. A network motif (or graphlet) is defined as a small connected sub-pattern which is over-represented in a network. Network motifs have been widely applied in a wide range of applications, namely biological, social, and technical networks. The counting of the network motif involves expensive enumeration of graph sub-patterns along with the detection of graph isomorphism. In general, network motif detection algorithms are computationally expensive and often designed to operate over …

Mathematics That Clarify Slope & Scale, Help Set Standards, And Improve Interrater Agreement On Time-Series Graphs, Chad Erick Liming Kinney Dec 2020

Mathematics That Clarify Slope & Scale, Help Set Standards, And Improve Interrater Agreement On Time-Series Graphs, Chad Erick Liming Kinney

Theses and Dissertations

This paper introduces new mathematic equations that clarify slope and scale and help overcome difficulties with visually interpreting slopes (or trends)--a significant culprit of poor interrater agreement (IRA) of graphed data. Three experiments tested applications of the equations and demonstrated the following results: (a) Graphic Variability Quotient (GVQ) manipulation strongly predicts viewer ratings (and accuracy) of behavior change, β = .895, R2 = .801, (b) mathematical standards that control the inherent variability in non-standard graphs can be empirically based (to facilitate reliable visual comparison), and (c) visual aids posted on graphs, such as angles of inclination and a simple slope …

STEM (science, technology, engineering, and mathematics) has gained significant notoriety and momentum in recent years. STEM literacy highlights the vital connection between an educated STEM workforce and U.S. national prosperity and leadership. STEM educational and job placement goals have been a national priority for over the past 20 years. However, the STEM gap is widening—contributing to increasing STEM pipeline leakage and the social injustice milieu of a noncompetitive workforce— undermining efforts to create prosperity and sustain global leadership. The pace of STEM jobs filled lags the rate of technological advancement and the surges in skilled STEM labor demand. The aggregate …

Machine Learning Based Predictions Of Dissolved Oxygen In A Small Coastal Embayment, Manuel Valera, Ryan K. Walter, Barbara A. Bailey, Jose E. Castillo Dec 2020

Machine Learning Based Predictions Of Dissolved Oxygen In A Small Coastal Embayment, Manuel Valera, Ryan K. Walter, Barbara A. Bailey, Jose E. Castillo

Physics

Coastal dissolved oxygen (DO) concentrations have a profound impact on nearshore ecosystems and, in recent years, there has been an increased prevalance of low DO hypoxic events that negatively impact nearshore organisms. Even with advanced numerical models, accurate prediction of coastal DO variability is challenging and computationally expensive. Here, we apply machine learning techniques in order to reconstruct and predict nearshore DO concentrations in a small coastal embayment while using a comprehensive set of nearshore and offshore measurements and easily measured input (training) parameters. We show that both random forest regression (RFR) and support vector regression (SVR) models accurately reproduce …

Scale‐Dependent Effects Of Host Patch Traits On Species Composition In A Stickleback Parasite Metacommunity, Daniel I. Bolnick, Emlyn J. Resetarits, Kimberly Ballare, Yoel E. Stuart, William E. Stutz Dec 2020

Scale‐Dependent Effects Of Host Patch Traits On Species Composition In A Stickleback Parasite Metacommunity, Daniel I. Bolnick, Emlyn J. Resetarits, Kimberly Ballare, Yoel E. Stuart, William E. Stutz

Biology: Faculty Publications and Other Works

A core goal of ecology is to understand the abiotic and biotic variables that regulate species distributions and community composition. A major obstacle is that the rules governing species distributions can change with spatial scale. Here, we illustrate this point using data from a spatially nested metacommunity of parasites infecting a metapopulation of threespine stickleback fish from 34 lakes on Vancouver Island, British Columbia. Like most parasite metacommunities, the composition of stickleback parasites differs among host individuals within each host population, and differs between host populations. The distribution of each parasite taxon depends, to varying degrees, on individual host traits …

Sediment Oxygen Demand And Stoichiometry Of Irl Nutrient Fluxes, Iulia Bibire Dec 2020

Sediment Oxygen Demand And Stoichiometry Of Irl Nutrient Fluxes, Iulia Bibire

Theses and Dissertations

Eutrophication of coastal systems has become a prominent global issue with a variety of detrimental effects, one of these being the shift in the composition of phytoplankton communities often promoting harmful algal blooms (HABs) resulting at least partially from changes to the relative abundance of N:P:Si. This study investigated nutrient fluxes from muck, a fine-grained and organic-rich sediment, and from sand to determine the importance of these sediments with regards to regulating N:P ratios in the water column. Overall sediment oxygen demand (SOD) was used as an indicator of aerobic decomposition and was found to decrease from north to south …

Current And Projected Water Reuse For Irrigation In Utah, R. Ryan Dupont, Joan E. Mclean, Randal S. Martin, Courtney Flint, L. Niel Allen, Jennifer L. Weidhaas

Reports

Reuse of treated wastewater for irrigation in some cases can help meet increasing agriculture and urban water demands in Utah. The last report describing existing and potential reuse efforts in Utah was in 2005 (Utah Division of Water Resources, 2005). This report provides information on existing and proposed water reuse and perceptions among water providers and users regarding the use of reclaimed wastewater. Wastewater reuse is one of many practices to conserve water and improve water quality. In a broad sense, water reuse occurs by downstream users, but in some cases, deliberate strategic reuse of water is undertaken to provide …

Promoting The Sustainability Of The Gulf Of Maine Recreational Groundfish Fishery Through Discard Mortality Estimation, Mitigation, And Outreach, Connor W. Capizzano Dec 2020

Promoting The Sustainability Of The Gulf Of Maine Recreational Groundfish Fishery Through Discard Mortality Estimation, Mitigation, And Outreach, Connor W. Capizzano

Graduate Doctoral Dissertations

Recreational fishing (i.e., angling), a popular leisure activity that provides socio-economic benefits to human societies around the world, can represent a significant source of fishing mortality and impact fish populations and marine ecosystems. Although fish are often released by recreational anglers to reduce fishing mortality rates, the efficacy of discarding fish is often criticized given that fish can die from the factors experienced during the capture, handling, and release process (i.e., discard mortality). Despite this recognition, the rate at which fish suffer discard mortality in specific commercial and recreational fisheries is often unknown and difficult to obtain due to logistical …

Novel Tools And Techniques To Investigate And Reduce The Impacts Of Capture-And-Handling, Ryan J. Knotek Dec 2020

Novel Tools And Techniques To Investigate And Reduce The Impacts Of Capture-And-Handling, Ryan J. Knotek

Graduate Doctoral Dissertations

Fish have been an important food resource for humans throughout history, but with growing populations increasing the demand for this resource, many fish stocks have become overfished. In response, management has traditionally addressed overfishing by establishing regulations that reduce the directed fishing mortality associated with harvesting. However, these practices often do not take into account the mortality associated with fish that are incidentally captured and discarded (as bycatch). This discard mortality (DM) can represent a potentially large source of removals for species that are particularly susceptible to the stressors of capture-and-handling and/or discarded at high rates. It is therefore vital …

Mosquito Microbiomes: Understanding The Interface Between Microbiome, Environment, And Human Pathogens, Amanda G. Tokash-Peters Dec 2020

Mosquito Microbiomes: Understanding The Interface Between Microbiome, Environment, And Human Pathogens, Amanda G. Tokash-Peters

Graduate Doctoral Dissertations

The study of mosquito microbiomes promises a deeper understanding of factors influencing interactions between mosquito hosts, human pathogens, and the environment. While several studies have focused on tripartite interactions between host, pathogen, and microbiome, far fewer have analyzed the environmental factors that shape these interactions and provide the basis for the formation of microbial communities in the mosquito host. Additionally, the use of Wolbachia and similar anti-arboviral symbionts in mosquitoes to control pathogen transmission has emerged as a popular idea for mosquito control and requires further investigation. The works presented here address changes in mosquito microbiomes, including the abundance of …

Asymmetry Between Activators And Deactivators In Functional Protein Networks, Ammar Tareen, Ned S. Wingreen, Ranjan Mukhopadhyay Dec 2020

Asymmetry Between Activators And Deactivators In Functional Protein Networks, Ammar Tareen, Ned S. Wingreen, Ranjan Mukhopadhyay

Physics

Are “turn-on” and “turn-off” functions in protein-protein interaction networks exact opposites of each other? To answer this question, we implement a minimal model for the evolution of functional protein-interaction networks using a sequence-based mutational algorithm, and apply the model to study neutral drift in networks that yield oscillatory dynamics. We study the roles of activators and deactivators, two core components of oscillatory protein interaction networks, and find a striking asymmetry in the roles of activating and deactivating proteins, where activating proteins tend to be synergistic and deactivating proteins tend to be competitive.

Elite human and animal athletes must acquire the fuels necessary for extreme feats, but also contend with the oxidative damage associated with peak metabolic performance. Here, we show that a migratory bird with fuel stores composed of more omega-6 polyunsaturated fats (PUFA) expended 11% less energy during long-duration (6 hr) flights with no change in oxidative costs; however, this short-term energy savings came at the long-term cost of higher oxidative damage in the omega-6 PUFA-fed birds. Given that fatty acids are primary fuels, key signaling molecules, the building blocks of cell membranes, and that oxidative damage has long-term consequences for …

Assimilating Through Consumption: A Rhetorical History Of The Early Years Of The Advocate, Cora Beth Butcher-Spellman Dec 2020

Assimilating Through Consumption: A Rhetorical History Of The Early Years Of The Advocate, Cora Beth Butcher-Spellman

Graduate Theses and Dissertations

This thesis uses analysis of constitutive rhetoric and queer archival methods to examines how The Advocate used assimilationist rhetoric and consumerist rhetoric in fundamentally anti-democratic ways to consolidate the form of ideal gay consumer-citizenship. Focusing on the first three years of the publication, I utilize queer theory and theories of citizenship and political economy to explain how The Advocate’s rhetoric and mainstream success allowed the publication to normalize a limited and politically weak gay identity. This thesis argues The Advocate’s rhetoric of exclusion, authority, and consumerism were three central features shaping ideal gay consumer-citizenship as most available to people who …

Evaluation Of Different Ensiling Methods On Storage And Feeding Value Of The Residual Material From Edamame Soybean Processing, Ellen Herring Dec 2020

Evaluation Of Different Ensiling Methods On Storage And Feeding Value Of The Residual Material From Edamame Soybean Processing, Ellen Herring

Graduate Theses and Dissertations

Use of organic waste material by ruminant animals from food processing operations potentially reduces costs and reduces environmental issues from disposal of these residues. Therefore, 2 experiments were conducted to evaluate the storage and feeding value of residual from edamame soybean processing for ruminant animals. Two types of waste streams, waste during harvest time and waste from processing stored material, were ensiled (on a laboratory scale) using various methods and effects on post-ensiling nutritive value were examined. Material from both waste streams were ensiled either without wilting or after wilting; each moisture level was ensiled with and without an inoculant. …
