Exploring The Neighborhood Preferences Of A Segment Of Millennials In Omaha, Nebraska, Aaron Kloke

Community and Regional Planning Program: Professional Projects

In 2010, Millennials, or those between 18 and 34, surpassed the Baby Boomers in population size. Today, Millennials, also known as Generation Y, make up over 25 percent of the United States’ population. In Omaha, they make up 26.9 percent of the population. The next largest generation in Omaha, the Baby Boomers, make for 19.2 percent of the population. Clearly, this emerging demographic has the ability to change the way we create and design our built environment if it so chooses.

To review how this generation may choose to change the way we design our future neighborhoods, national trends were …

Gis Spatial Analysis Of Segregation Clustering Evolution In Lincoln, Nebraska, Sarah Aftika

Community and Regional Planning Program: Theses

Rising immigration growth in the Midwest creates Multi-racial communities and segregation such as social class segregation, economic segregation, education segregation, and also housing segregation. In urban America, there are three major sets of explanatory causal factors that have been hypothesized to explain ethnic residential segregation. They are: housing discrimination, socioeconomic status (SES) and ethnic group preferences (French 2008, 1).

Lincoln, as a metro city in Nebraska, shows signs of segregation phenomena as well as other metro cities in Midwest. The analysis tool used for this study is Geographic Information System (GIS) spatial analysis. This tool enables us to examine the …

Improving Drought Management For Transboundary River Basins In The United States Through Collaborative Environmental Planning, Crystal J. Bergman

School of Natural Resources: Dissertations, Theses, and Student Research

Increasing demand for water and the uncertainty of climate change have put pressure on the global water supply, presenting one of the greatest challenges of the 21^st Century for human development. Drought is a natural hazard that further compromises water supply and increases competition among water use sectors. These challenges confirm the need for comprehensive water supply and drought planning. Planning for water, however, is often conducted within political boundaries that are not consistent with the water resource’s natural boundaries, which can result in conflict. Collaborative environmental planning is a sub-discipline of planning that can address the occurrence of …

An Alternative American Approach To Repositories [Open Repositories 2014 Proposal], Paul Royster

University of Nebraska-Lincoln Libraries: Presentations

The repository community has many organizations, experts, consultants, and “thought leaders” prepared to give direction and advice to the developers and managers of institutional repositories. This presentation is about how one repository (ours) has found success by rejecting much of their “conventional” wisdom and “expert” advice. We have declined to support the SPARC Addendum, promote campus mandates, encourage Creative Commons licensing, use open-source software, rely on faculty self-archiving, or require peer-review for original publishing; and we are not even considered truly “open” access by SPARC or the hard-line “libre” adherents.

Yet we are the second-largest U.S. institutional repository, with more …

The Imperial Temple At Antiochia Ad Cragum: Aspects Of Architecture And Iconography, Geraldine S. Dobos

School of Art, Art History, and Design: Theses and Student Creative Work

Along the northeastern Mediterranean shore lies Antiochia ad Cragum, an ancient city located in the western area of the Roman province of Rough Cilicia. It is now known as the village of Guney, in southern Turkey. The Northeast Temple is the first Imperial structure at Antiochia that has been revealed in its entirety and its reconstruction is anticipated. This excavation by the University of Nebraska (Antiochia ad Cragum Archaeological Research Project, or ACARP), is directed by UNL Professor Michael Hoff.

The hypothetical reconstruction of the Northeast Temple’s geison course, which I present, emphasizes certain diagnostic features that may be used …

Range Wars, Ryan H. Edgington

University of Nebraska Press: Sample Books and Chapters

Established in south-central New Mexico at the end of World War II, White Sands Missile Range is the largest overland military reserve in the western hemisphere. It was the site of the first nuclear explosion, the birthplace of the American space program, and the primary site for testing U.S. missile capabilities.

In this environmental history of White Sands Missile Range, Ryan H. Edgington traces the uneasy relationships between the military, the federal government, local ranchers, environmentalists, state game and fish personnel, biologists and ecologists, state and federal political figures, hunters, and tourists after World War II—as they all struggled to …

Music Along The Rapidan, James A. Davis

University of Nebraska Press: Sample Books and Chapters

In December 1863, Civil War soldiers took refuge from the dismal conditions of war and weather. They made their winter quarters in the Piedmont region of central Virginia: the Union’s Army of the Potomac in Culpeper County and the Confederacy’s Army of Northern Virginia in neighboring Orange County. For the next six months the opposing soldiers eyed each other warily across the Rapidan River.

In Music Along the Rapidan James A. Davis examines the role of music in defining the social communities that emerged during this winter encampment. Music was an essential part of each soldier’s personal identity, and Davis …

Biofuels From Crop Residue Can Reduce Soil Carbon And Increase Co2 Emissions, Adam J. Liska, Haishun Yang, Maribeth Milner, Steve Goddard, Humberto Blanco-Canqui, Matthew P. Pelton, Xiao X. Fang, Haitao Zhu, Andrew E. Suyker

Adam Liska Papers

Removal of corn residue for biofuels can decrease soil organic carbon(SOC) and increase CO₂ emissions because residue C in biofuels is oxidized to CO₂ at a faster rate than when added to soil. Net CO2 emissions from residue removal are not adequately characterized in biofuel life cycle assessment (LCA). Here we used a model to estimate CO₂ emissions from corn residue removal across the US Corn Belt at 580 million geospatial cells. To test the SOC model, we compared estimated daily CO₂ emissions from corn residue and soil with CO₂ emissions measured using eddy covariance, …

Forecasting The Spread Of Raccoon Rabies Using A Purpose-Specific Group Decision-Making Process., Aaron M. Anderson, Stephanie A. Shwiff, Richard B. Chipman, Todd C. Atwood, Tyler Cozzens, Frank Fillo, Robert Hale, Brody Hatch, Joanne Maki, Olin E. Rhodes Jr., Erin E. Rees, Charles E. Rupprecht, Rowland Tinline, Kurt C. Vercauteren, Dennis Slate

United States Department of Agriculture Wildlife Services: Staff Publications

The Centers for Disease Control (CDC) and USDA Wildlife Services (WS) have been involved in an oral rabies vaccination (ORV) program for raccoons (Procyon lotor) that has slowed the westward spread of raccoon rabies. The objective of this study was to forecast the spread of the disease if an ORV zone was not maintained. A group decision-making process was designed to address the forecasting problem and was implemented using a group of 15 experts and 4 support personnel at a meeting at the USDA National Wildlife Research Center. Ten expansion regions were constructed that described the spread of …

Hybridization Between Previously Isolated Ancestors May Explain The Persistence Of Exactly Two Ancient Lineages In The Genome Of The Oyster Parasite Perkinsus Marinus, Peter C. Thompson, Benjamin M. Rosenthal, Matthew P. Hare

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Theory predicts that neutral genetic variation accumulates within populations to a level determined by gains through mutation and losses by genetic drift. This balance results in a characteristic distribution of allelic variation with the maximum allelic difference determined by effective population size. Here, we report a striking departure from these expectations in the form of allelic dimorphism, observed at the majority of seven loci examined in Perkinsus marinus, an important oyster parasite that causes Dermo disease. DNA sequences were collected from five loci flanking microsatellite repeats and two loci coding for superoxide dismutase enzymes that may mediate the parasite’s interaction …

Hymenolepis Robertrauschi N. Sp. From Grasshopper Mice Onychomys Spp. In New Mexico And Nebraska, U.S.A., Scott Lyell Gardner, Brent A. Luedders, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

From 1989 through 1998, a total of 358 grasshopper mice were collected and examined for helminth and protistan parasites from several habitat types on the Sevilleta Long Term Ecological Research (LTER) site in New Mexico, U.S.A. Of these, 205 individuals were identified as Onychomys leucogaster (Wied-Neuwied 1841) and 153 individuals were classified as O. arenicola Mearns 1896. Many individuals of Onychomys were infected with a new species of Hymenolepididae (Hymenolepis robertrauschi), which is herein described, illustrated, and compared with all species of Nearctic Hymenolepis s. str. Hymenolepis robertrauschi was found in 26% of the individuals of O. arenicola …

Empirical Examination Of The Factors Regulating Thunderstorm Initiation, Noah A. Lock, Adam L. Houston

Department of Earth and Atmospheric Sciences: Faculty Publications

Initiation is the part of the convective life cycle that is currently least understood and least well forecast. The inability to properly forecast the timing and/or location of deep convection initiation degrades forecast skill, especially during the warm season. To gain insight into what atmospheric parameters distinguish areas where storms initiate from areas where they do not initiate, over 55 000 thunderstorm initiation points over the central United States from 2005 to 2007 are found and a number of thermodynamic and kinematic parameters are computed from 20-km Rapid Update Cycle (RUC)-2 data. In addition to the initiation points, data are …

The Dynamics Of Animal Social Networks: Analytical, Conceptual, And Theoretical Advances, Noa Pinter-Wollman, Elizabeth A. Hobson, Jennifer E. Smith, Andrew Edelman, Daizaburo Shizuka, Shermin De Silva, James Waters, Steven D. Prager, Takao Sasaki, George Wittemyer, Jennifer Fewell, David B. Mcdonald

Papers in Behavior in Biological Sciences

Social network analysis provides a broad and complex perspective on animal sociality that is widely applicable to almost any species. Recent applications demonstrate the utility of network analysis for advancing our understanding of the dynamics, selection pressures, development, and evolution of complex social systems. However, most studies of animal social networks rely primarily on a descriptive approach. To propel the field of animal social networks beyond exploratory analyses and to facilitate the integration of quantitative methods that allow for the testing of ecologically and evolutionarily relevant hypotheses, we review methodological and conceptual advances in network science, which are underutilized in …

Greek Affiliation And Education Abroad: A Quantitative Study Of The Role Of Greek Involvement In Study-Abroad Experiences, Luke Paul Martens Bretscher

Department of Educational Administration: Dissertations, Theses, and Student Research

The purpose of this quantitative study was to understand the impact that Greek affiliation has on the education-abroad experience. Specifically, the study examined whether there were differences in the experiences of Greek and non-Greek undergraduate education-abroad participants.

The central question for the study was: Are there differences in participation and experiences in education-abroad activities between students affiliated with social Greek letter organizations and students who are not affiliated with social Greek letter organizations? The researcher examined four different experiential differences: rate, influences to participate, barriers, and educational outcomes.

By examining 705 current University of Nebraska—Lincoln students who had study-abroad experiences, …

Ecology And Diversity Of Cockroaches (Dictyoptera: Blattaria) From The Virgin Islands, Wenhua Lu, Barry D. Valentine, Daniel E. Perez-Gelabert, Esteban Gutiérrez

Insecta Mundi

The Virgin Islands (except St. Croix) are geologically part of the Puerto Rico Bank and biologically related to Puerto Rico, but their cockroaches (Dictyoptera: Blattaria) were not yet as well studied as those on Puerto Rico. To elucidate the number of species, life history, range distribution, and seasonal abundance of these cockroaches, we have conducted a quantitative study since June 2000 using a Malaise trap on Guana Island, British Virgin Islands, in addition to other conventional collecting methods. We found 21 species: Blattella germanica (Linnaeus), Cariblatta antiguensis (Saussure and Zehntner), Cariblatta sp. 2, Cariblatta sp. 3, Colapteroblatta sp. 1, Eurycotis …

State Drought Programs And Plans: Survey Of The Western United States, Matthew M. Fontaine, Anne C. Steinemann, Michael Hayes

National Drought Mitigation Center: Faculty Publications

Drought preparedness programs are considered a primary defense against drought hazards. This article investigates state drought programs in the western United States, including a review of drought plans and interviews with state drought officials. While nearly all states have developed drought plans and larger drought programs, the scope and depth of these programs vary widely. State programs and plans typically address monitoring, declaration and response, and communication and coordination. Yet few states conduct postdrought assessments or impact and risk assessments. Resources tend to be allocated more for drought response than mitigation. Officials emphasized not only the importance of available monitoring …

Temperature Changes In Central Asia From 1979 To 2011 Based On Multiple Datasets, Zengyun Hu, Chi Zhang, Q. Steven Hu, Hanqin Tian

Department of Earth and Atmospheric Sciences: Faculty Publications

The arid and semiarid region in central Asia is sensitive and vulnerable to climate variations. However, the sparse and highly unevenly distributed meteorological stations in the region provide limited data for understanding of the region’s climate variations. In this study, the near-surface air temperature change in central Asia from 1979 to 2011 was examined using observations from 81 meteorological stations, three local observation validated reanalysis datasets of relatively high spatial resolutions, and the Climate Research Unit (CRU) dataset. Major results suggested that the three reanalysis datasets match well with most of the local climate records, especially in the low-lying plain …

Mitochondrial Diversity Supports Multiple Origins For Invasive Pigs, Blake E. Mccann, Mathew J. Malek, Robert A. Newman, Brandon S. Schmit, Seth R. Swafford, Richard A. Sweitzer, Rebecca B. Simmons

United States Department of Agriculture Wildlife Services: Staff Publications

Our objective was to identify and evaluate mitochondrial diversity of wild pigs in the United States (U.S.). We obtained tissue samples from 81 individual pigs in 30 U.S. states and amplified a 403 basepair region of mitochondrial DNA. We then downloaded overlapping sequences (n¼904) from public repositories to create a global reference. We used parsimony and Bayesian techniques to evaluate phylogenetic relationships, and we used origins of published sequences from Eurasian wild boar to establish a phylogeographic reference. We then compared gene and nucleotide diversity measures for introduced pigs in North America with those of domestic swine, Eurasian wild boar, …

Status Of 10 Additional Bird Species Of Conservation Concern In Us Fish & Wildlife Service Region 6, Christopher J. Butler, Jeffrey B. Tibbits, Katrina Hucks

United States Fish and Wildlife Service: Publications

American Bitterns are medium-sized, brown herons which inhabit large wetlands with dense emergent vegetation. Their cryptic coloration allows them to blend in well with dead emergent vegetation, and American Bitterns have a tendency to “freeze” with the bill pointing up if they feel threatened.

They breed from Newfoundland west to British Columbia (generally south of 55 °N latitude) and south to California, northern New Mexico, and northeastern North Carolina. American Bitterns generally winter in areas where the average temperature remains above freezing. Their winter distribution stretches from Maryland (rarely New Jersey) south to Florida, west to California, south through Mexico …

A Life History Perspective On Skin Cancer And The Evolution Of Skin Pigmentation, Daniel L. Osborne, Raymond B. Hames

Department of Anthropology: Faculty Publications

The ancestral state of human skin pigmentation evolved in response to high ultraviolet radiation (UVR) stress. Some argue that pigmentation evolved to limit folate photolysis, therein limiting neural tube defects. Pigmentation also protects against sunburn which decreases the efficiency of sweating and potentiates skin infection. Pigmentation increases the efficacy of skin as a barrier to infection. Skin cancer has been rejected or minimized as a selective pressure because it is believed to have little or no effect on mortality during reproductive years. This argument ignores evidence of human longevity as a derived life history trait and the adaptive value of …

Although the continued existence of the species is unknown and some possibly are extinct there are five recently extant species, including one species that is described here as new. The holotypes for all available names are pictured, and synonymies discussed and updated. Lectotypes are designated for Apterocyclus honoluluensis Waterhouse and A. munroi Sharp. A key to species and a revised catalog for the genus are provided.

Using Art To Assess Environmental Education Outcomes, Ami G. Flowers, John P. Carroll, Gary T. Green, Lincoln R. Larson

School of Natural Resources: Faculty Publications

Construction of developmentally appropriate tools for assessing the environmental attitudes and awareness of young learners has proven to be challenging. Art-based assessments that encourage creativity and accommodate different modes of expression may be a particularly useful complement to conventional tools (e.g. surveys), but their efficacy and feasibility across diverse contexts has not been adequately explored. To examine the potential utility of integrating art into evaluations of environmental education outcomes, we adapted an existing drawing prompt and corresponding grading rubric to assess the environmental attitudes and awareness of children (ages 6–12) at summer camps in Athens, GA, USA (n = …

School of Natural Resources: Faculty Publications

The exchange of carbon dioxide is a key measure of ecosystem metabolism and a critical intersection between the terrestrial biosphere and the Earth’s climate. Despite the general agreement that the terrestrial ecosystems in North America provide a sizeable carbon sink, the size and distribution of the sink remain uncertain. We use a data-driven approach to upscale eddy covariance flux observations from towers to the continental scale by integrating flux observations, meteorology, stand age,aboveground biomass, and a proxy for canopy nitrogen concentrations from AmeriFlux and Fluxnet-Canada Research Network as well as a variety of satellite data streams from the MODIS sensors. …

Wilderness Preserves: Still Relevant And Resilient After All These Years, Sandra Zellmer, John M. Anderies

Nebraska College of Law: Faculty Publications

This chapter explores the continuing relevance of preserving wilderness by preventing active human intervention. It concludes that the symbolic and ecological benefits of wilderness are as significant today as they were fifty years ago. Indeed, the importance of preserving wilderness areas will only increase as the climate changes. Land managers face complex challenges, however, when they are managing wilderness resources that are already degraded due to climate change or other human impacts and that may require intervention to prevent further degradation. Deciding whether and how to intervene with active management tools while maintaining the overarching “wild” values of wilderness is …
