Evaluating Mobile-Based Citizen Science In Increasing Citizen Participants In Environmental Management, Wenqi Ou

Community and Regional Planning Program: Theses

Mobile-based citizen science as thriving citizen education tool increases the non-expert citizen involvement in the scientific world by encouraging the public upload nature observation to assist scientific research while learning scientific knowledge. Mobile-base citizen science as social media has potential to facilitate citizen engagement in the environmental management. Based on the conceptual framework of citizen science incorporation with environmental management, large users in the program foster the citizen involvement in the environmental management. Research here applies SWOT (Strength, Weakness, Opportunity, Threats) analysis to evaluate mobile based citizen science regarding data management, citizen participation, and partnership. It revealed the current status …

The Geochemistry Of Loess: Asian And North American Deposits Compared, Daniel R. Muhs

United States Geological Survey: Staff Publications

Loess is widely distributed over Asia and North America and constitutes one of the most important surficial deposits that serve as terrestrial records of the Quaternary. The oldest Pleistocene loess in China is likely ∼2.6 Ma, thus spanning much or all of the Pleistocene. In North America, most loess is no older than the penultimate glacial period, with the exception of Alaska, where the record may go back to ∼3.0 Ma. On both continents, loess deposits date primarily to glacial periods, and interglacial or interstadial periods are represented by paleosols. Both glacial and non-glacial sources of silts that comprise the …

The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard

Zea E-Books Collection

This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly …

Housing Availability, Accessibility And Affordability For Nebraska's Rural Aging Populations, Jordan G. Grummert Rasmussen

Community and Regional Planning Program: Theses

Rural America and the nation as a whole has entered a phase of significant demographic change, as the number of Americans over the age of 65 is estimated to double by 2050. Nebraska counties and the state are, too, experiencing this shift in the age demographic. As the population ages, consideration must be given to the housing options for older adults, specifically those who reside and wish to remain in rural areas.

While broad consideration is given to either population aging or housing in rural areas, there is limited county level analysis adjoining these demographic and housing realities. This study …

Benefits Of Public R&D In U.S. Agriculture: Spill-Ins, Extension And Roads, S L. Wang, A Plastina, Lilyan E. Fulginiti, E. Ball

Department of Agricultural Economics: Faculty Publications

This paper uses panel data for the 1980-2004 period to estimate the contributions

of public research to US agricultural productivity growth. Local and social

internal rates of return are estimated accounting for the effects of R & D

spill-in, extension activities and road density. R & D spill-in proxies were constructed

based on both geographic proximity and production profile to examine

the sensitivity of the rates of return to these alternatives. We find that

extension activities, road density, and R & D spill-ins, play an important role

in enhancing the benefit of public R & D investments. We also find …

Beyond The City Lights: A Multiple-Case Study Of Successful, Experienced Secondary Science Teachers In Rural Schools, Beverly R. Devore-Wedding

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

Recruitment and retention concerns for teachers, particularly in rural school districts and in science, fill the daily news and research literature. The shortage of STEM workers is also another concern as well. Then why do nationally recognized secondary science teachers remain in rural schools with lower salaries, increased responsibilities beyond teaching content, and multi-preparations, stay in those schools? How do they overcome challenges in their schools?

This multiple case study focuses on Presidential Award for Excellence in Mathematics and Science Teaching (PAEMST) awardees who have taught secondary science in rural school districts 10 years or more. Eight rural PAEMST high …

Moving From Forecast To Prediction: How Honors Programs Can Use Easily Accessible Predictive Analytics To Improve Enrollment Management, Joseph A. Cazier, Leslie Sargent Jones, Jennifer Mcgee, Mark Jacobs, Daniel Paprocki, Rachel A. Sledge

Journal of the National Collegiate Honors Council Online Archive

Most enrollment management systems today use historical data to build rough forecasts of what percentage of students will likely accept an offer of enrollment based on historical acceptance rates. While this aggregate forecast method has its uses, we propose that building an enrollment model based on predicting an individual’s likelihood of matriculation can be much more beneficial to an honors director than a historical aggregate forecast. Many complex predictive analytics techniques and specialized software can build such models, but here we show that a basic approach can also be easily accessible to honors directors where a small amount of data …

Do Advisors Perceive Climate Change As An Agricultural Risk? An In-Depth Examination Of Midwestern U.S. Ag Advisors’ Views On Drought, Climate Change, And Risk Management, Sarah P. Church, Michael Dunn, Nicholas Babin, Amber Saylor Mase, Tonya Haigh, Linda Stalker Prokopy

National Drought Mitigation Center: Faculty Publications

Through the lens of the Health Belief Model and Protection Motivation Theory, we analyzed interviews of 36 agricultural advisors in Indiana and Nebraska to understand their appraisals of climate change risk, related decision making processes and subsequent risk management advice to producers. Most advisors interviewed accept that weather events are a risk for US Midwestern agriculture; however, they are more concerned about tangible threats such as crop prices. There is not much concern about climate change among agricultural advisors. Management practices that could help producers adapt to climate change were more likely to be recommended by conservation and Extension advisors, …

Dispatches From Flyover Country: Four Appraisals Of Impacts Of Trump’S Immigration Policy On Families, Schools, And Communities, Edmund T. Hamann, Cara Morgenson

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

A university professor and high school ESL teacher, both based in Lincoln Nebraska, each write two short essays that detail implications of the Trump administration immigration policies for students, teachers, schools, and communities. The first two dispatches come from the transition period (after Trump won but while Obama still presided) while the latter two come from the 50-day mark of the Trump presidency. Juxtaposing voices contrasts overarching impact with the local; juxtaposing chronologies allows comparison of political promises and threats to early actions and reactions.

Arts Education Funding, Annette M. Vargas

Journal of Women in Educational Leadership

Student access to arts education, and the quality of such instruction in the nation’s public schools, continue to be of concern to policymakers, educators, and families. Specifically, research has focused on the questions: To what extent do students receive instruction in the arts? Under what conditions is the instruction provided? The passing of the Every Student Succeeds Act (ESSA) was a significant move by the Senate, as they had not considered K-12 public education legislation on the Senate floor since 2001. Under this federal law, the arts are included as part of a “well-rounded education” requiring that the …

Information In The Ecosystem: Against The “Information Ecosystem”, Timothy B. Norris, Todd Suomela

Copyright, Fair Use, Scholarly Communication, etc.

The “information ecosystem” metaphor is widely used in academic libraries and has become nearly ubiquitous when speaking of the information systems that support scholarly communication and varied forms of data sharing and publication. The trending use of this language arises from non-academic applications — for example in big data (the Hadoop ecosystem) or software development (the node.js ecosystem) — and there remains little critical examination of the use of this metaphor. Indeed, the definition of ecosystem as the set of relations between living organisms and their surrounding non-living environment is apparently not directly a part of the metaphor. This paper …

A Splendid Torch: Learning And Teaching In Today’S Academic Libraries, Jodi Reeves Eyre, John C. Maclachlan, Christa Williford

Copyright, Fair Use, Scholarly Communication, etc.

In the winter of 2015, a handful of current and former CLIR postdoctoral fellows gathered at a small restaurant in Washington, D.C., to celebrate publication of The Process of Discovery: The CLIR Postdoctoral Fellowship Program and the Future of the Academy. In typical CLIR fellowship alumni fashion, it took about an hour of relaxation before we began to look at one another and ask, “Now what?” Over fried pickles, barbecue brisket, and vegan spare ribs, we decided to recreate the Collaborative Writing Group (CWG) experience that fostered the collection of essays about what we had learned from our work in …

Model Application Niche Analysis: Assessing The Transferability And Generalizability Of Ecological Models, Jessica B. Moon, Theodore H. Dewitt, Melissa N. Errend, Randall J. F. Bruins, Mary E. Kentula, Sarah J. Chamberlain, M. Siobhan Fennessy, Kusum J. Naithani

United States Environmental Protection Agency: Publications

The use of models by ecologists and environmental managers, to inform environmental management and decision-making, has grown exponentially in the past 50 yr. Due to logistical, economical, and theoretical benefits, model users frequently transfer preexisting models to new sites where data are scarce. Modelers have made significant progress in understanding how to improve model generalizability during model development. However, models are always imperfect representations of systems and are constrained by the contextual frameworks used during their development. Thus, model users need better ways to evaluate the possibility of unintentional misapplication when transferring models to new sites. We propose a method …

Utilizing A Consumer-Grade Camera System To Quantify Surface Reflectance, Joseph J. Lehnert

Department of Geography: Dissertations, Theses, and Student Research

Consumer-grade camera systems are often employed in aerial remote sensing to provide insight into patterns and processes of interest to science and industry, a trend that has largely been encouraged by the rapid growth of the small unmanned aircraft system (sUAS) industry. However, little research exists on the ability of these systems to accurately measure surface reflectance in specific wavebands, a crucial consideration for many remote sensing applications. This research was conducted on the premise that with proper equipment and calibration techniques consumer-grade cameras would be capable of accurately measuring surface reflectance in user-defined wavebands of interest. A stereo-pair, Fujifilm …

Evaluation Of Host Plant Resistance Against Sunflower Moth, Homoeosoma Electellum(Hulst), In Cultivated Sunflower In Western Nebraska, Dawn M. Sikora

Department of Entomology: Dissertations, Theses, and Student Research

Sunflower moth, Homoeosoma electellum, is a serious pest of oilseed and confection sunflowers. In this study, we determine efficacy of resistance against this pest. Thirty commercial hybrids, inbreds, and varieties of sunflowers were tested in replicated field and laboratory studies. Trait efficacy is determined by pericarp strength by means of physical compression tests and damage to achenes. Initial sunflower entries were planted May 2014 and data collection began in early August 2014. A second season was planted June 2015, with sampling beginning late August the same year.

In 2014, oilseed varieties showed a strength average of 2.71 ± 0.11 N …

Communication And Family Identity: Toward A Conceptual Model Of Family Identity And Development Of The Family Identity Inventory, Kaitlin Elizabeth Phillips

Department of Communication Studies: Dissertations, Theses, and Student Research

Families serve as a primary socializing agent in the lives of individuals (Soliz & Rittenour, 2012), and the first social identity individuals have in their lives. Given the complexity and importance of identity—and family identity specifically, the goal of this study is to identify the various dimensions of family identity that scholars and practitioners should account for in their work. Through a two-study exploratory sequential mixed-method design I investigate what constructs comprise a conceptual model of family identity, and I develop a corresponding inventory of Family Identity. Through this process, I will also assess the relationships among these communicative processes, …

Around 50 experts from the fields of Ancient History, Indo-European Studies, Semitic Philology, Assyriology, Classical Archaeology, and Terminology from twelve different countries came together at the Centre for Textile Research, to discuss textile terminology, semantic fields of clothing and technology, loan words, and developments of textile terms in Antiquity. They exchanged ideas, research results, and presented various views and methods.

This volume contains 35 chapters, divided into five sections: • Textile terminologies across the ancient Near East and the …

Moving From Generalisations To Specificity About Mangrove –Saltmarsh Dynamics, Kerrylee Rogers, Ken W. Krauss

United States Geological Survey: Staff Publications

Spatial and temporal variability in factors influencing mangrove establishment and survival affects the distribution of mangrove, particularly near their latitudinal limit, where mangrove expansion into saltmarsh is conspicuous. In this paper the spatial variability in mangrove distribution and variability in factors influencing mangrove establishment and survival during the Quaternary period are reviewed, focusing on research at latitudinal limits in Australia and mainland USA. Despite similarities in the response of mangrove to some drivers, the expression of these drivers is both spatially and temporally variable, demonstrating the need for analyses of mangrove-saltmarsh dynamics to move beyond generalizations and incorporate regional and …

Nuclear Weapons In A Changing Climate: Probability, Increasing Risks, And Perception, Adam Liska, Tyler R. White, Eric Holley, Robert J. Oglesby

Adam Liska Papers

Many people tend to think that the outcome of any nuclear weapons use today will result in an escalatory situation with apocalyptic outcomes for the countries involved. Yet many factors are increasing the probability of the limited use of nuclear weapons (e.g., 1 to 20 warheads) in a range of conflict scenarios. Previous atmospheric model simulations of regional nuclear conflicts employing many relatively small bombs have been estimated to cause a global “nuclear autumn,” with great reductions in agricultural productivity, stratospheric ozone loss, and spread of hazardous radioactive fallout. The totality of these effects would result in widespread damage …

A Historical Geography Of Six And Eight-Man Football In Nebraska, Andrew Husa

Department of Geography: Dissertations, Theses, and Student Research

This thesis serves as both a historical geography of six and eight-man football in Nebraska and a discussion of their relationship to rural depopulation. After beginning with an introduction to six and eight-man football, I present an overview of the entire state, including the historical geography of six and eight-man football teams, backgrounds of schools closing and consolidating, and the new trend of cooperative sports teams. This overview is accompanied by maps at five-year intervals depicting the high schools playing six and eight-man football. Rural depopulation, which has plagued the state since the Great Depression, can be seen expressed in …

Mesonets: Mesoscale Weather And Climate Observations For The United States, Rezaul Mahmood, Ryan Boyles, Kevin Brinson, Christopher Fiebrich, Stuart Foster, Ken Hubbard, David Robinson, Jeff Andresen, Dan Leathers

High Plains Regional Climate Center: Staff Publications

Mesoscale in situ meteorological observations are essential for better understanding and forecasting the weather and climate and to aid in decision-making by a myriad of stakeholder communities. They include, for example, state environmental and emergency management agencies, the commercial sector, media, agriculture, and the general public. Over the last three decades, a number of mesoscale weather and climate observation networks have become operational. These networks are known as mesonets. Most are operated by universities and receive different levels of funding. It is important to communicate the current status and critical roles the mesonets play. Most mesonets collect standard meteorological data …

Measurement Of Commodity Price Risk: An Overview Of Brazilian Agricultural Markets, Daniel Henrique Dario Capitani, Fabio Mattos

Department of Agricultural Economics: Faculty Publications

This study explores different procedures to estimate price risk in commodity markets. Focusing on Brazilian agricultural markets, the paper proposes to assess both dispersion and downside risk measures using five different approaches (volatility, coefficient of variation, lower partial moments, value at risk and conditional value at risk). Results suggest that some commodities have large price variability but small downside risk, while other commodities show small price variability and large downside risk. Thus, there is no single answer to the question of which commodity exhibits more price risk, but rather distinct answers depending on how risk is perceived by different individuals. …

The Iconic One-Hit Wonder: The History And Reception Of Franz Biebl's Ave Maria, Matthew Oltman

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

Franz Biebl’s Ave Maria is one of the most well-known small-scale choral pieces written in the latter half of the twentieth century. Since its introduction to American choirs in 1970, it has become an important part of the standard choral repertoire and is often performed perennially, especially at Christmas. It was integral to the rise in popularity of Chanticleer, the American professional male chorus, and remains closely associated with the ensemble thanks to it being recorded and published in the United States under Chanticleer’s auspices. Despite these facts, very little has been written about the composer or his iconic setting …

Bat Community Composition And Monitoring For White-Nose Syndrome At First State National Historical Park, Delaware And Pennsylvania, Juliet Nagel, J. Edward Gates

United States National Park Service: Publications

Abstract

In recent years, bats have faced increasingly deadly threats on multiple fronts. Cave-dwelling bats have been decimated by the emergence of a disease, white-nose syndrome (WNS), caused by a fungal pathogen, Pseudogymnoascus destructans; and tree bats are dying in large numbers at wind power facilities. First State National Historical Park (FRST) is a new national park unit located in northern Delaware and Pennsylvania. Prior to this study, little information was available on bat species and their activity and distribution within FRST. To fill this knowledge gap, we conducted an inventory of bat species present at FRST. We used …
