The Effects Of Urbanization On Fear In Wildlife, Sarah Spier, Joseph J. Fontaine

Department of Environmental Studies: Undergraduate Student Theses

Through this study we sought out to determine if Fox Squirrels in Lincoln, Nebraska exhibited a change in response to aerial versus terrestrial predators in urban areas. We addressed the possible consequences that human disturbance has on daily stimuli, predator behaviors, and, in turn, prey behaviors. Specifically, the experiment exposed Fox Squirrels to the vocalizations and visual models of an aerial predator, terrestrial predator, and a control species. Squirrels did not show a significant change in behavior between predator types. However, fox squirrels displayed correct anti-predator behaviors by only responding to the predators and not the control. The time it …

Soybean Development: The Impact Of A Decade Of Agricultural Change On Urban And Economic Growth In Mato Grosso, Brazil, Peter Richards, Heitor Pellegrina, Leah Vanwey, Stephanie A. Spera

Geography and the Environment Faculty Publications

In this research we consider the impact of export-driven, soybean agriculture in Mato Grosso on regional economic growth. Here we argue that the soybean sector has served as a motor to the state’s economy by increasing the demand for services, housing, and goods, and by providing a source of investment capital to the non-agricultural sector. Specifically, we show that each square kilometer of soybean production supports 2.5 formal sector jobs outside of agriculture, and the equivalent of approximately 150,000 US in annual, non-agricultural GDP. We also show that annual gains in non-agricultural employment and GDP are closely tied to soybean …

Relationship Between High School Math Course Selection And Retention Rates At Otterbein University, Lauren A. Fisher

Undergraduate Honors Thesis Projects

Binary logistic regression was used to study the relationship between high school math course selection and retention rates at Otterbein University. Graduation rates from postsecondary institutions are low in the United States and, more specifically, at Otterbein. This study is important in helping to determine what can raise retention rates, and ultimately, graduation rates. It directs focus toward high school math course selection and what should be changed before entering a post-secondary institution. Otterbein will have a better idea of what type of students to recruit and which students may be good candidates with some extra help. Recruiting is expensive, …

Analysis Of The Energy Spectrum Of Michel Electrons In Microboone, Philip Griffith Kellogg

Undergraduate Honors Thesis Projects

The MicroBooNE experiment at Fermilab was designed both to investigate results from anomalies seen in short-baseline experiments and to prototype technology for larger scale experiments. MicroBooNE hopes to investigate an excess of low-energy events seen in a preceding experiment, using improved detector resolution. The goal of this thesis was to perform a calibration of the MicroBooNE detector by determining the Michel electron energy spectrum inside the detector. Michel electrons result from the decay of muons, and have a very well understood energy spectrum. Muons from cosmic rays continually pass through the detector, roughly 1% of which will decay within the …

Suspension Electrospinning Carbon Nanotube Doped Poly (Vinyl Alcohol) Nanowires, Ryan Hensleigh

Honors Theses

The synthesis, characterization and application of carbon nanotubes (CNTs) have received substantial attention in recent years, particularly in the field of polymer nanomaterial composites (PNCs). CNTs possess impressive thermal, electrical and mechanical properties, and PNCs incorporating them have shown multitude increases in these same properties with relatively low percolation thresholds [1]. Electrospinning is an effective and tunable materials synthesis platform for the manufacture of micro and nanofibers that has shown particular promise in the fields of carbon nanotube PNC processing due to the favorable isotropic alignment CNTs undergo due to the electrospinning process [2]. CNT alignment has been shown to …

The Effect Of Changes In Ph On The Production And Respiration Rates Of Native Tape Grass, Vallisneria Americana, Adam Parker

Student Writing

In the past century, the world has seen an increase in the amount of carbon dioxide (CO2) in the atmosphere. The rise in CO2 can put stress on aquatic ecosystems due to ocean acidification, an overall decrease in the pH of the ocean’s waters. Freshwater ecosystems, already stressed by pollution and recent increases in the number of invasive species are also showing signs of acidification due to the increase in CO2. The effect of the rise in acidity is known to be harmful to calcifying organisms, but the effect on freshwater submerged aquatic vegetation (SAV) is not well studied. The …

Climate Change And Land Management Impact Rangeland Condition And Sage-Grouse Habitat In Southeastern Oregon, Megan K. Creutzburg, Emilie B. Henderson, David R. Conklin

Environmental Science and Management Faculty Publications and Presentations

Contemporary pressures on sagebrush steppe from climate change, exotic species, wildfire, and land use change threaten rangeland species such as the greater sage-grouse (Centrocercus urophasianus). To effectively manage sagebrush steppe landscapes for long-term goals, managers need information about the potential impacts of climate change, disturbances, and management activities. We integrated information from a dynamic global vegetation model, a sage-grouse habitat climate envelope model, and a state-and-transition simulation model to project broad-scale vegetation dynamics and potential sage-grouse habitat across 23.5 million acres in southeastern Oregon. We evaluated four climate scenarios, including continuing current climate and three scenarios of global …

Revisiting The Renner–Teller Effect In The X ̃2Π State Of Ccn: Pulsed Discharge-Supersonic Jet Single Vibronic Level Emission Spectroscopy, Lloyd Godfrey Muzangwa, Scott Reid

Chemistry Faculty Research and Publications

The CCN radical is a prototypical system for study of the Renner–Teller effect in its degenerate X ̃²Π ground state, with a number of experimental and theoretical studies carried out over the past 50 years. Most experimental studies have focused on the low-lying vibrational structure as observed in the high-resolution spectra of hot bands, or in emission. In this work, we have used pulsed-discharge supersonic-jet single vibronic level (SVL) emission spectroscopy from selected levels of the Ã²Δ state to probe the vibronic structure of X ̃²Π up to ∼6000 cm⁻¹ above the …

The Impact Of Imperfect Information On Network Attack, A. Melchionna, Jesus Caloca, S. Squires, T. Antonsen, E. Ott, M. Girvan

McNair Scholars Research Journal

This paper explores the effectiveness of network attack when the attacker has imperfect information about the network. For Erdös-Rényi networks, we observe that dynamical importance and betweenness centrality-based attacks are surprisingly robust to the presence of a moderate amount of imperfect information and are more effective compared with simpler degree-based attacks even at moderate levels of network information error. In contrast, for scale-free networks the effectiveness of attack is much less degraded by a moderate level of information error. Furthermore, in the Erdös-Rényi case the effectiveness of network attack is much more degraded by missing links as compared with the …

Novel Magnetic And Optical Properties Of Sn1-XZnXO2 Nanoparticles, Nevil Franco

McNair Scholars Research Journal

In this work, we report on the effects of doping SnO₂ nanoparticles with Zn²⁺ ions. A series of ~2- 3nm sized Sn_{1- x}Zn_xO₂ crystallite samples with 0 ≤ x ≤ 0.18 were synthesized using a forced hydrolysis method. Increasing dopant concentration caused systematic changes in the crystallite size, oxidation state of Sn, visible emission and band gap of SnO₂ nanoparticles. X-ray Diffraction (XRD) studies confirmed the SnO₂ phase purity and the absence of any impurity phases. Magnetic measurements at room temperature showed a weak ferromagnetic behavior characterized by an open hysteresis …

Raising Arrowrock: A Political Ecology Case Study, Richard Martinez

McNair Scholars Research Journal

The US Army Corps of Engineers (Corps) currently evaluates construction alternatives for the Arrowrock Dam’s future. The process presents a uniquely complex situation as policy, public, and private interests converge. The fear of flooding and availability of irrigation water have deeply influenced the economics through which federal agencies justified building dams in the early 20th century. However, the current political, economic, and environmental stakeholders grapple to fulfill their interests. Furthermore, major policies such as the National Environmental Protection Act, Endangered Species Act, and state protections on the upper tributaries of the Boise River convolute the final decision set for 2017.

Global Network Inference From Ego Network Samples: Testing A Simulation Approach, Jeffrey A. Smith

Department of Sociology: Faculty Publications

Network sampling poses a radical idea: that it is possible to measure global network structure without the full population coverage assumed in most network studies. Network sampling is only useful, however, if a researcher can produce accurate global network estimates. This article explores the practicality of making network inference, focusing on the approach introduced in Smith (2012). The method uses sampled ego network data and simulation techniques to make inference about the global features of the true, unknown network. The validity check here includes more difficult scenarios than previous tests, including those that go beyond the initial scope conditions of …

An Mas Based Energy Management System For A Stand-Alone Microgrid At High Altitude, Junhui Zhao, Bo Zhao, Meidong Xue, Xuesong Zhang, Caisheng Wang

Electrical & Computer Engineering and Computer Science Faculty Publications

A multi-agent system based energy management system (EMS) is proposed in this paper for implementing a PV-small hydro hybrid microgrid (MG) at high altitude. Based on local information, the distributed generation (DG) sources in the MG are controlled via the EMS to achieve efficient and stable system operation. Virtual bidding is used to quickly establish the scheduling of system operation and capacity reserve. In addition, real-time power dispatches are carried out through model predictive control to balance load demand and power generation in the MG. The dynamic model and the energy management strategy of the MG have been simulated on …

Microbial Communities Of The Providence River, Jacqueline Kratch

Honors Projects in Science and Technology

The Providence River has been industrialized for over one-hundred years. Industries such as oil storage and metal recycling facilities have left high levels of pollutant metals, including lead (Pb), in the soil and water. The elevated Pb concentrations in these environments influence the selection of Pb resistance mechanisms in the bacterial community1. One mechanism of heavy metal resistance is the Pb efflux pump, consisting of proteins in the cell membrane that aid in the transport of Pb out of the cell2. In this study we investigated the co-occurrence of Pb efflux pumps and antibiotic efflux pumps in bacteria from Pb …

All Capstone Projects

There is currently a great need for a tool to search cooking recipes based on ingredients, country and recipe type. Current search engines do not provide this feature. Most of the recipe search results in current websites are not efficiently clustered based on relevance or categories resulting in a user getting lost in the huge search results presented. They also do not provide links to view images of the ingredients of a recipe.

My project aims to combine the features like search based on ingredients, suggestions for similar recipes, and images for the ingredients under one search engine and provide …

Big Data Analytics By Using Hadoop, Chaitanya Arava, Sudharshan Bandaru, Saradhi Bhargava Reddy Tiyyagura

All Capstone Projects

Data is large and vast, with more data coming into the system every day. Summarization analytics are all about grouping similar data together and then performing an operation such as calculating a statistic, building an index, or just simply counting.

Filtering is more about understanding a smaller piece of your data, such as all records generated from a particular user, or the top ten most used verbs in a corpus of text. In short, filtering allows you to apply a microscope to your data. It can also be considered a form of search.
