Geog 140: Human Geography—A Peer Review Of Teaching Project Inquiry Portfolio—"Music And The Geography Of Place: Engaging The Geographical Imagination", Katherine Nashleanas

UNL Faculty Course Portfolios

The present project uses cooperative learning strategies that requires students in large classes to collaborate in applying intellectually challenging articles on place, space, sacred spaces, tourist places, and commodification of place to the development of a video project linking music to place and landscape. As an extension of their group activity, students are teaching each other how to apply concepts from the assigned articles to their projects in creative ways while engaging in critical thinking and exercising their geographical imagination.

Entomology 101: Introduction To Entomology, Brian Kelly

Department of Entomology: Distance Master of Science Projects

The goal of this particular project is to create an entry-level curriculum for Entomology to present to the local university / community college. My Bachelor’s Degree was obtained from the University of Colorado at Colorado Springs (UCCS). The higher institutions of learning in the city of Colorado Springs (to include Pikes Peak Community College, or PPCC, as well) lack any courses relating to Entomology. UCCS has a strong presence in the city and is growing by leaps and bounds, currently enrolling about 13,000 students and expanding its degree programs. PPCC has several campuses around town, and offers many elective courses …

Creating A Community Of Practice To Prevent Suicide Through Multiple Channels: Describing The Theoretical Foundations And Structured Learning Of Pc Cares, Lisa Wexler, Diane Mceachern, Gloria Difulvio, Cristine Smith, Louis F. Graham, Kirk Dombrowski

Department of Sociology: Faculty Publications

It is critical to develop practical, effective, ecological, and decolonizing approaches to indigenous suicide prevention and health promotion for the North American communities. The youth suicide rates in predominantly indigenous small, rural, and remote Northern communities are unacceptably high. This health disparity, however, is fairly recent, occurring over the last 50 to 100 years as communities experienced forced social, economic, and political change and intergenerational trauma. These conditions increase suicide risk and can reduce people’s access to shared protective factors and processes. In this context, it is imperative that suicide prevention includes—at its heart— decolonization, while also utilizing the “best …

The Space Of Art, Michael R. Hill

Department of Sociology: Faculty Publications

Three years ago, Tami Miller challenged me to think formally about “the concept of space as creative grounds for enlivenment and immersion,” and today’s talk revisits part of the lecture I gave here in 2013.3 The ideas presented then — as now — are grounded in my university training, research and teaching in the interrelated disciplines of geography, design studies, landscape architecture, community and regional planning, and sociology.

While mostly skipping over the concept of “time” (that’s quite another discussion), I will review five spatial constructs and related ideas useful in our work as docents.

Rural And Urban Communities, Emily Kazyak

Department of Sociology: Faculty Publications

This entry describes how LGBTQ individuals in rural areas have different experiences from those of LGBTQ individuals in urban areas. It outlines how understandings about cities and small towns have been intertwined with understandings about LGBTQ identities as well as what current demographic data show with regard to where LGBTQ people live in the United States. Then the entry details LGBTQ identities and communities in urban contexts. It ends by describing LGBTQ identities and communities in rural contexts. Throughout, attention is paid to the diversity of experiences within each context.

Assessment Of Selected Antibiotic Resistances In Ungrazed Native Nebraska Prairie Soils, Lisa M. Durso, David A. Wedin, John E. Gilley, Daniel N. Miller, David B. Marx

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

The inherent spatial heterogeneity and complexity of antibioticresistant bacteria and antibiotic resistance (AR) genes in manureaffected soils makes it difficult to sort out resistance that can be attributed to human antibiotic use from resistance that occurs naturally in the soil. This study characterizes native Nebraska prairie soils that have not been affected by human or food-animal waste products to provide data on background levels of resistance in southeastern Nebraskan soils. Soil samples were collected from 20 sites enumerated on tetracycline and cefotaxime media; screened for tetracycline-, sulfonamide-, b-lactamase–, and macrolide-resistance genes; and characterized for soil physical and chemical parameters. All …

Geographic Variation, Null Hypotheses, And Subspecies Limits In The California Gnatcatcher: A Response To Mccormack And Maley, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda

School of Natural Resources: Faculty Publications

We interpreted the results of nuclear DNA sequencing to be inconsistent with the recognition of California Gnatcatcher (Polioptila californica) subspecies. McCormack and Maley (2015) suggested that our data did support 2 taxa, one of which was P. c. californica, listed as Threatened under the Endangered Species Act (ESA). We summarize here how 2 sets of researchers with access to the same data reached different conclusions by including different analyses. We included the southern subspecies’ boundary from the taxonomy of Atwood (1991), the taxonomic basis for the ESA listing, which resulted in an Analysis of Molecular Variance that …

Dynamic Data Management In A Data Grid Environment, Björn Barrefors

School of Computing: Dissertations, Theses, and Student Research

A data grid is a geographically distributed set of resources providing a facility for computationally intensive analysis of large datasets to a large number of geographically distributed users. In the scientific community, data grids have become increasingly popular as scientific research is driven by large datasets. Until recently, developments in data management for data grids have focused on management of data at lower layers in the data grid architecture. With dataset sizes expected to approach exabyte scale in coming years, data management in data grids are facing a new set of challenges. In particularly, the problem of automatically placing and …

From Literacy To Literacies: Negotiating Multiple Literacies In The English Classroom, Breanne S. Campbell

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

This dissertation is a narrative description of my teaching moves as I attempted to negotiate within my classroom both traditional print literacy and new literacies afforded by emerging technology. In this study, I sought to reconcile my rhetoric with my reality (Zeichner, 1999) by teaching students how to read and design multimodal compositions within the traditional framework and curriculum required by my school district. Students composed traditional memoirs and then participated in the synaesthesia process by remediating their memoirs using technology. Students were also asked to write a Statement of Goals and Choices (Shipka, 2011), reflecting on their own rhetorical …

Variability In The Selection Patterns Of Pronghorn: Are They Really Native Prairie Obligates?, Paul F. Jones, Mike Grue, Mike Suitor, Darren J. Bender, Cormack Gates, Dale Eslinger, Julie Landry-Deboer

The Prairie Naturalist

In Canada, pronghorn (Antilocapra americana) are primarily considered a native prairie obligate because of their reliance on open grassland vegetation communities, although an assessment of local ecological knowledge suggests that pronghorn in Alberta select a variety of habitat from native prairie to cultivated lands. The primary objective of our study was to assess whether pronghorn in Alberta and Saskatchewan are native prairie obligates. Specifically, we addressed the following questions: 1) do individual pronghorn show similar selection patterns for native prairie and, therefore, support the notion that they are prairie obligates; 2) do pronghorn show consistent resource selection patterns …

Open-Channel Computation With R, Michael C. Koohafkan, Bassam A. Younis

The R Journal

The rivr package provides a computational toolset for simulating steady and unsteady one dimensional flows in open channels. It is designed primarily for use by instructors of undergraduate and graduate-level open-channel hydrodynamics courses in such diverse fields as river engineering, physical geography and geophysics. The governing equations used to describe open-channel flows are briefly presented, followed by example applications. These include the computation of gradually varied flows and two examples of unsteady flows in channels—namely, the tracking of the evolution of a flood wave in a channel and the prediction of extreme variation in the water-surface profile that results when …

Bsgs: Bayesian Sparse Group Selection, Kuo-Jung Lee, Ray-Bing Chen

The R Journal

An R package BSGS is provided for the integration of Bayesian variable and sparse group selection separately proposed by Chen et al. (2011) and Chen et al. (in press) for variable selection problems, even in the cases of large p and small n. This package is designed for variable selection problems including the identification of the important groups of variables and the active variables within the important groups. This article introduces the functions in the BSGS package that can be used to perform sparse group selection as well as variable selection through simulation studies and real data.

The study describes African American female students’ perceptions of factors that influence their achievement in school. Participants included six African American female students attending high school in the Midwest. Data was gathered from student interviews, parent/guardian questionnaires, informal observations, and student visual displays. From the analysis of the aforementioned data several themes emerged which include the importance of the students’ family and teachers to their …

Contaminant Source Management Options For Wellhead Protection, Victoria Nelson

Community and Regional Planning Program: Professional Projects

Before regulations were introduced to protect the general public from waterborne illnesses, it was common for people to become sick and even die from contaminated drinking water. Many rivers and streams in the United States were so polluted that they were uninhabitable for wildlife and dangerous to human health. The pollution and contamination in the surface and groundwater caused a public out-cry for the government to step in and do something about the hazardous water conditions. As the U.S. government started regulating surface water, it realized that the main source of drinking water for half of the U.S. and 95% …

Land-Use Change Impact On Soil Sustainability In A Climate And Vegetation Transition Zone, K. D. Reitsma, B. H. Dunn, U. Mishra, S. A. Clay, T. Desutter, D. E. Clay

United States Department of Energy: Publications

A growing world population and climate change are expected to influence future agricultural productivity and land use. Th is study determined the impact of land-use change on soil sustainability and discussed the factors contributing to these changes. South Dakota was selected as a model system because corn (Zea mays L.) grain prices tripled between 2006 and 2012 and it is located in a climate and grassland/cropland transition zone. High resolution imagery was used to visually determine land uses (cropland, grassland, nonagricultural, habitat, and water) at 14,400 points in 2006 and 2012. At each point, land-use change and the USDA land …

Long-Term Corn And Soybean Response To Crop Rotation And Tillage, Aaron J. Sindelar, Marty R. Schmer, Virginia L. Jin, Brian J. Weinhold, Gary E. Varvel

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

Long-term experiments are essential to understand how crop rotation and tillage practices affect corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production and its resiliency to variable weather conditions. A 28-yr rainfed experiment was conducted in Nebraska to evaluate continuous corn (CC), the corn phase of corn–soybean rotation (CS), continuous soybean (SS), and the soybean phase of corn–soybean rotation (SC), and tillage system (chisel [CH], tandem disk [DK], moldboard plow [MP], no-till [NT], ridge-tillage [RT], and subsoil tillage [ST]) on grain yield and yield stability. In 19 of 28 yr, CS yields were greater than CC, …

The Vulnerability Of Indo-Pacific Mangrove Forests To Sea-Level Rise, Catherine E. Lovelock, Donald R. Cahoon, Daniel A. Friess, Glenn R. Guntenspergen, Ken W. Krauss, Ruth Reef, Kerrylee Rogers, Megan L. Saunders, Frida Sidik, Andrew Swales, Neil Saintilan, Le Xuan Thuyen, Tran Triet

United States Geological Survey: Staff Publications

Sea-level rise can threaten the long-term sustainability of coastal communities and valuable ecosystems such as coral reefs, salt marshes and mangroves^1,2. Mangrove forests have the capacity to keep pace with sea-level rise and to avoid inundation through vertical accretion of sediments, which allows them to maintain wetland soil elevations suitable for plant growth³. The Indo- Pacific region holds most of the world’s mangrove forests⁴, but sediment delivery in this region is declining, owing to anthropogenic activities such as damming of rivers⁵. This decline is of particular concern because the Indo-Pacific region is …

Switchgrass Germplasm Resources, Michael D. Casler, Kenneth P. Vogel, Melanie Harrison

Department of Agronomy and Horticulture: Faculty Publications

Switchgrass (Panicum virgatum L.) is an important native grass and dominant member of the tallgrass prairie ecosystem. It is used for conservation, restoration, livestock feed production, and bioenergy feedstock production. The purpose of this review is to describe the biological and geographical basis for switchgrass germplasm diversity and to provide a resource for scientists and outreach personnel to find switchgrass germplasm to meet their needs. Upland and lowland ecotypes represent the most important polymorphism in switchgrass, with distinct but overlapping geographic distributions. Variation in ploidy exists within both ecotypes, with 2n = 4x = 36 the dominant ploidy …

Fluctuating Fire Regimes And Their Historical Effects On Genetic Variation In An Endangered Shrubland Specialist, Hernan Vázquez-Miranda, Kelly R. Barr, C. Craig Farquhar, Robert M. Zink

School of Natural Resources: Faculty Publications

The Pleistocene was characterized by worldwide shifts in community compositions. Some of these shifts were a result of changes in fire regimes, which influenced the distribution of species belonging to fire-dependent communities. We studied an endangered juniper–oak shrubland specialist, the black-capped vireo (Vireo atricapilla). This species was locally extirpated in parts of Texas and Oklahoma by the end of the 1980s as a result of habitat change and loss, predation, brood parasitism, and anthropogenic fire suppression. We sequenced multiple nuclear loci and used coalescence methods to obtain a deeper understanding of historical population trends than that typically available …

The Ed.D. As Investment In Professional Development: Cultivating Practitioner Knowledge, Margaret A. Macintyre Latta, Edmund T. Hamann, Susan Wunder

Department of Teaching, Learning, and Teacher Education: Faculty Publications

As teacher educators and participants in the US-based Carnegie Project for the Education Doctorate (CPED) initiative to differentiate the Ed.D/Ph.D., we have programmatic commitments to the centrality of practitioner knowledge for shaping professional development. Through CPED, we structure opportunities for local educators to develop their professional practices within their graduate studies toward an Ed.D, while maintaining full-time educational work commitments. Concurrently, we examine and document how CPED creates room, alongside concrete practice, to cultivate, promote, and value the voices, sensibilities, and capacities of practitioners engaged in advanced practices. In doing so, we confront marginalization of practitioners’ perspectives in the field …

The Conceptualization Of Self-Identity Among Residents Of Appalachia Ohio, Jessica L. Krok-Schoen, Angela L. Palmer-Wackerly, Phokeng M. Dailey, Janice L. Krieger

Department of Communication Studies: Faculty Publications

Social identity and its association to culture, place, and health is an important, but understudied, area of research. One social group that illustrates this connection between place and identity is people living in Appalachia. This exploratory mixed-method study investigates the appropriateness of the self-concept of Ohio Appalachian adults with cancer as “Appalachian,” the context associated with that identity and its association with community identification, rural identity, Appalachian Regional Commission (ARC) status, demographic data, and clinical trial (CT) enrollment. Forty-nine adults with cancer residing in Appalachia were recruited. Participants were cancer patients who (1) were offered a randomized clinical cancer trial; …

Reconciling Lgb And Christian Identities In The Rural South, Brandi Woodell, Emily Kazyak, D'Lane Compton

Department of Sociology: Faculty Publications

Drawing on in-depth interviews with rural Christians living in the South who identify as lesbian, gay, and bisexual (LGB), this study analyzes how they negotiate their religious, geographic, and sexual identities. We find that most interviewees employed two strategies to reconcile their Christian and gay identities: emphasizing a personal connection to an accepting God and finding a local church in their rural community in which they felt accepted. We argue that rural contexts influenced interviewees’ reliance on these strategies and show how individuals can construct multiple interpretations about themselves, which do not always align with existing cultural assumptions. In addition, …

Prescribed Fire Monitoring Report, Tallgrass Prairie National Preserve 2014 (Iqcs Fire Number 285382, 285383, 266782, 285677), Sherry A. Leis, Sarah E. Hinman

United States National Park Service: Publications

Introduction

In 2014, the preserve’s federal and NGO partners conducted prescribed fires during March, April, and October that encompassed 8129.8 acres of Tallgrass Prairie National Preserve (TAPR). This was a unique burn year in that prescribed burns occurred in the spring, the traditional burn season, and the fall. Fall burns were conducted to support needed archaeological surveys as part of the environmental compliance for a symphony event scheduled for June 2015 at the preserve. Burns at TAPR were coordinated with local US Fish and Wildlife Service (USFWS), The Nature Conservancy (TNC), and various units of the National Park Service.

Thanatourism, Caminata Nocturna, And The Complex Geopolitics Of Mexico’S Parque Ecoalberto, Marouf A. Hasian Jr., José Ángel Maldonado, Kent A. Ono

Department of Communication Studies: Faculty Publications

This article provides readers with a critical analysis of Mexico’s Parque EcoAlberto. Utilizing some of the theoretical work of interdisciplinary scholars who are interested in the study of “thanatourism,” the authors illustrate how this park, with its Caminata Nocturna (night hike), is much more than simply a “dark” tourist attraction that deters those who might travel North to the U.S. border. This study shows how the indigenous Hñähñú in Mexico have to confront a host of symbolic and material forces that are sometimes hidden in the patriotic metanarratives that swirl around this park.

Landscape Position Influences Microbial Composition And Function Via Redistribution Of Soil Water Across A Watershed, Zhe Du, Diego Andrés Riveros-Iregui, Ryan T. Jones, Timothy R. Mcdermott, John E. Dore, Brian L. Mcglynn, Ryan E. Emanuel, Xu Li

Department of Civil and Environmental Engineering: Faculty Publications

Subalpine forest ecosystems influence global carbon cycling. However, little is known about the compositions of their soil microbial communities and how these may vary with soil environmental conditions. The goal of this study was to characterize the soil microbial communities in a subalpine forest watershed in central Montana (Stringer Creek watershed within the Tenderfoot Creek Experimental Forest) and to investigate their relationships with environmental conditions and soil carbonaceous gases. As assessed by tagged Illumina sequencing of the 16S rRNA gene, community composition and structure differed significantly among three landscape positions: high upland zones (HUZ), low upland zones (LUZ), and riparian …

Tacit Cultural Knowledge: An Instrumental Qualitative Case Study Of Mixed Methods Research In South Africa, Debra Rena Miller

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Notwithstanding the dramatic expansion of mixed methods research, research methodologies, methods, and findings are culturally situated. Problematically, studies conducted outside the global north often embrace canonical methodologies aimed at understanding concepts more explicit than tacit. Learning about the needs of researchers and participants in South Africa may bring to light taken-for-granted assumptions in Anglo-American orientations of mixed methods. Hence, the purpose of this study is to explore aspects of tacit cultural knowledge that contextualize mixed methods research in South Africa.

In-person interviews among South African professors as well as a corpus of books, sections, journal articles, and theses informed the …

Increasing Ecosystem Services Benefits Through Spatially Coordinated Land Management: Role Of Transaction Costs And Communication In An Experimental Setting, Simanti Banerjee, Timothy N. Cason, Frans P. De Vries, Nick Hanley

Cornhusker Economics

The delivery of ecosystem services benefits from proenvironmental land use and land management activities on farmland can often be substantially enhanced if landowners are able to coordinate their decisions across space. For example, in the face of pollinator population collapse, greater crop pollination benefits will accrue if neighboring farmers commit to reducing pesticide usage, than if only a single farmer unilaterally curbs use, leaving bees vulnerable to pesticide drift from neighboring farms. Other examples which illustrate the importance of spatial coordination for generating environmental benefits across space are water quality improvement and biodiversity protection via reduction in habitat fragmentation.
