Leadership Journeys: Reflections On Experiences And Challenges From Women In Academic Leadership, Sarah L. Smiley, Andrea G. Zakrajsek, Kathryn L. Fletcher

Journal of Women in Educational Leadership

Although the number of women holding administrative positions in higher education has risen over the past two decades, the gender gap in academic leadership in higher education institutions persists. Barriers exist to prevent women from entering these positions, including those related to workplace culture and personal considerations. This qualitative exploratory study interviewed 38 women leaders in positions ranging from Assistant Dean to President at universities in a mid-west athletic conference. It asked the following research questions: How did they enter academic leadership? What were their experiences in leadership positions? What advice would they offer to other women considering leadership positions …

Profile Of Producers And Production Of Dry-Aged Beef In Brazil, Jonatã Henrique Rezende-De-Souza, Flavio Andre Bolini Cardello, Ana Paula Moraes De Paula, Felipe A. Ribeiro, Chase C. Calkins, Sérgio Bertelli Pflanzer

Department of Animal Science: Faculty Publications

No information is currently available on the profile of producers and production process of dry-aged beef in Brazil, to the best of the authors’ knowledge. We surveyed 37 Brazilian companies that were producing dry-aged beef in 2020 to investigate this market. The absolute and relative frequency of responses was calculated to obtain the sum, average, minimum, and maximum values. From the respondents, dry-aged beef was first produced in 2009, and most producers are located in big cities. Most respondents control and monitor chamber temperature; however, humidity and air velocity only are monitored. The aging period (mostly between 22 to 60 …

Multiracial Individuals And Educational Testing, Karen Alexander

The Nebraska Educator: A Student-Led Journal

A literature review focused on quantitative measures and methods regarding multiracial individuals and educational testing revealed that multiracial individuals are uniquely different than monoracial individuals in terms of their racial identity and these unique identities interact with test scores. Until recently, this uniqueness has been ignored by institutions and within the field of educational testing. The uniqueness of multiracial identity should be taken into consideration when using test measures to make decisions for selection and when comparing group outcomes. The review provides a brief picture regarding the history of categorization of multiracial individuals and current research which connects the multiracial …

Association Between Aqueous Atrazine And Pediatric Cancer In Nebraska, Jagadeesh Puvvula, Shannon L. Bartelt-Hunt, Balkiss S. Ouattara, Alan S. Kolok, Jesse E. Bell, Eleanor G. Rogan

Department of Civil and Environmental Engineering: Faculty Publications

Agrichemicals, chemicals used to maximize crop and animal production, can lead to water quality concerns when these chemicals run off into surface and groundwater after precipitation events. In Nebraska, one such chemical is atrazine, a suspected carcinogen. This study evaluated the association between atrazine in surface and groundwater, in relation to the incidence of pediatric cancer in Nebraska watersheds over 30 years (1 January 1987 to 31 December 2016). The watersheds were grouped into four categories based on the average atrazine concentration over the study period, using quantile classification. The associations between atrazine (ground/surface) and pediatric cancer after adjusting for …

Crest Or Trough? How Research Libraries Used Emerging Technologies To Survive The Pandemic, So Far, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

Introduction

In the first months of the COVID-19 pandemic, it was impossible to tell if we were at the crest of a wave of new transmissions, or a trough of a much larger wave, still yet to peak. As of this writing, as colleges and universities prepare for mostly in-person fall 2021 semesters, case counts in the United States are increasing again after a decline that coincided with easier access to the COVID vaccine. Plans for a return to campus made with confidence this spring may be in doubt, as we climb the curve of what is already the second …

A Study Of Retention And Recruitment At Southern And Midwestern Weekly U.S. Newspapers, Jessica Fargen Walsh, Jill Martin

College of Journalism and Mass Communications: Faculty Publications

Daily and weekly newspapers are closing at alarming rates, leaving readers without local coverage in many parts of the country. More than 5,000 of the remaining newspapers in the United States are weeklies, providing meeting coverage, agricultural news and keeping small towns informed. Yet, not nearly enough research exists about the people working at those newspapers. More than 1,000 email surveys were sent in early 2021 to weekly news editors, publishers or owners in seven states seeking opinions on successes and challenges in hiring and retaining weekly journalists. Survey results and follow-up interviews revealed a number of insights including data …

Satellite-Detected Ammonia Changes In The United States: Natural Or Anthropogenic Impacts, Yaqian He, Rongting Xu, Stephen A. Prior, Di Yang, Anni Yang, Jian Chen

United States Department of Agriculture Wildlife Services: Staff Publications

Ammonia (NH3) is the most abundant alkaline component and can react with atmospheric acidic species to form aerosols that can lead to numerous environmental and health issues. Increasing atmospheric NH3 over agricultural regions in the US has been documented. However, spatiotemporal changes of NH3 concentrations over the entire US are still not thoroughly understood, and the factors that drive these changes remain unknown. Herein, we applied the Atmospheric Infrared Sounder (AIRS) monthly NH3 dataset to explore spatiotemporal changes in atmospheric NH3 and the empirical relationships with synthetic N fertilizer application, livestock manure production, and climate factors across the entire US …

A Machine Learning Interpretation Of The Contribution Of Foliar Fungicides To Soybean Yield In The North‐Central United States, Denis A. Shah, Thomas R. Butts, Spyridon Mourtzinis, Juan I. Rattalino Edreira, Patricio Grassini, Shawn P. Conley, Paul D. Esker

Department of Agronomy and Horticulture: Faculty Publications

Foliar fungicide usage in soybeans in the north-central United States increased steadily over the past two decades. An agronomically-interpretable machine learning framework was used to understand the importance of foliar fungicides relative to other factors associated with realized soybean yields, as reported by growers surveyed from 2014 to 2016. A database of 2738 spatially referenced fields (of which 30% had been sprayed with foliar fungicides) was fit to a random forest model explaining soybean yield. Latitude (a proxy for unmeasured agronomic factors) and sowing date were the two most important factors associated with yield. Foliar fungicides ranked 7th out of …

West Nile virus(WNV) is a globally distributed mosquito-borne virus of great public health concern. The number of WNV human cases and mosquito infection patterns vary in space and time. Many statistical models have been developed to understand and predict WNV geographic and temporal dynamics. However, these modeling efforts have been disjointed with little model comparison and inconsistent validation. In this paper, we describe a framework to unify and standardize WNV modeling efforts nationwide. WNV risk, detection, or warning models for this review were solicited from active research groups working in different regions of the United States. A total of 13 …

Prediction Of Biome-Specific Potential Evapotranspiration In Mongolia Under A Scarcity Of Weather Data, Khulan Batsukh, Vitaly A. Zlotnik, Andrew E. Suyker, Paolo Nasta

Department of Earth and Atmospheric Sciences: Faculty Publications

We propose practical guidelines to predict biome-specific potential evapotranspiration (ET_p) from the knowledge of grass-reference evapotranspiration (ET₀) and a crop coefficient (K_c) in Mongolia. A paucity of land-based weather data hampers use of the Penman–Monteith equation (FAO-56 PM) based on the Food and Agriculture Organization (FAO) guidelines to predict daily ET₀. We found that the application of the Hargreaves equation provides ET₀ estimates very similar to those from the FAO-56 PM approach. The K_c value is tabulated only for crops in the FAO-56 guidelines but is unavailable …

Conversational Style In Training, Megan Paul

Umbrella Summaries

What is conversational style?

Conversational style refers to a combination of stylistic strategies to personalize instructional text (oral or written) for learners. These include “the use of first and second rather than third person, directly addressing the reader, revealing [the author’s] personal beliefs, and/or using polite forms of address” (Ginns et al., 2013, p. 452). The following excerpts illustrate such styles:

“During inhaling, the [your] diaphragm moves down creating more space for the [your] lungs” (Mayer et al., 2004)

“Let me tell you what happens when lightning forms” (vs. just the scientific description; Moreno & Mayer, 2000)

“You are about …

Essays On The Designs And Benefits Of Land Conservation Programs, Badri Khanal

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This dissertation analyzes the policy designs and economic benefits of a land conservation practice called prairie strips. The first chapter investigates the impact of policy designs on individual household preferences. The study measures the value that Iowa residents place on the ecosystem services of prairie strips and determines if that value changes under different policy designs. The policy design treatment varies in who runs the program and who has enrollment priority. The willingness to pay (WTP) for ecosystem services is estimated using stated preferences from a choice experiment. Results indicate significant public support for expanding and funding the prairie strips …

Department of Child, Youth, and Family Studies: Faculty Publications

The influence of community-built environments on physical activity (PA) support in Early Childhood Education settings (ECEs) is unknown. The purpose of this cross-sectional study was to determine associations between community PA environments and ECE classroom PA practices. We included licensed Oklahoma ECE directors serving 3-to-5-year-old children. Parks and playground locations were exported from Google Earth. NationalWalkability Index was derived from 2010 US Census data. ArcMap 10.6 was used to geocode ECE locations, which were within an Activity Desert if no parks/playgrounds were located within a 1-mile radius or if Walkability Index was 10.5 or below. Classroom PA practices were determined …

Starting School Socially And Behaviorally Ready: The Impacts Of Malleable Home- And School-Based Relationships And Community Setting, Rachel Schumacher

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

Children growing up in disadvantage often enter school without the requisite social, emotional, and behavioral skills to be successful. Considering the importance of social-emotional skills for school and later life success, it is critical to understand factors associated with social-emotional development across the transition to elementary school. The current study will utilize an ecological approach to identify the influence of malleable home- (i.e., parent-child relationship [microsystem]) and school-based (i.e., home-school connection [mesosystem]) contextual factors over time (chronosystem) on children’s school readiness and social-emotional adjustment to early elementary school, and uncover the role of community setting (exosystem) in understanding children’s school …

Perceptions Of Future Community And Individual Well-Being In Rural Nebraska, Amanda L. Kowalewski

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Populations of rural areas continue to decline, yet some communities are more vibrant than ever. While past research has studied current satisfaction or well-being, few have examined future well-being. Using an ordinal logistic regression and combining primary and secondary data sources, this study investigates the predictors of rural Nebraskan’s sense of future well-being, both at the community and individual levels. The model indicates that resilience may be more important in well-being than social capital. Additionally, certain satisfaction indicators are more important than others. Factor analysis was employed to re-index variables, and findings were similar. Social capital, resilience, and quality of …

Mesopredator Frugivory Has No Effect On Seed Viability And Emergence Under Experimental Conditions, John P. Draper, Trisha B. Atwood, Noelle G. Beckman, Karin M. Kettenring, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Members of the order Carnivora are a unique and important seed disperser who consume and deposit undamaged seeds while providing regular long-distance seed dispersal opportunities. Some members of Carnivora, such as coyotes (Canis latrans), are undergoing range expansions which may help the plant species they consume colonize new locations or replace dispersal services provided by recently extirpated species. In this study, we evaluated aspects of the seed dispersal effectiveness of coyotes and gut passage time to determine the potential dispersal distances for three commonly consumed and commonly occurring plant species (Amelanchier alnifolia, Celtis ehrenbergiana, and Juniperus osteosperma). We also investigated …

Finite Element Modelling And Exergy Analysis Of A Solar Thermal Hollow Fiber Vacuum Membrane Distillation System, Benjamin Shuldes

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

A finite element model was developed to investigate the performance of a vacuum membrane distillation module under various operating conditions and membrane parameters. Porosity, tortuosity, pore diameter, membrane thickness, and fiber length were varied along with feed temperature, velocity, and flow configuration. In all cases, boundary layer polarization phenomena were seen to inhibit the performance of the module. At certain conditions, for a 7.5 cm fiber, the reduction in permeate flux from 65 LMH (Liter/m²/h) at the inlet to below 45 LMH at the outlet of the fibers was observed. In most cases, salt concentration polarization was the …

Generalist Bird Exhibits Site-Dependent Resource Selection, Samantha M. Cady, Craig A. Davis, Samuel D. Fuhlendorf, Rheinhardt Scholtz, Daniel R. Uden, Dirac Twidwell

Department of Agronomy and Horticulture: Faculty Publications

Quantifying resource selection (an organism's disproportionate use of available resources) is essential to infer habitat requirements of a species, develop management recommendations, predict species responses to changing conditions, and improve our understanding of the processes that underlie ecological patterns. Because study sites, even within the same region, can differ in both the amount and the arrangement of cover types, our objective was to determine whether proximal sites can yield markedly different resource selection results for a generalist bird, northern bobwhite (Colinus virginianus). We used 5 years of telemetry locations and newly developed land cover data at two, geographically distinct but …

Downscaling Of Far-Red Solar-Induced Chlorophyll Fluorescence Of Different Crops From Canopy To Leaf Level Using A Diurnal Data Set Acquired By The Airborne Imaging Spectrometer Hyplant, Bastian Siegmann, Maria Pilar Cendrero-Mateo, Sergio Cogliati, Alexander Damm, John Gamon, David Herrera, Christopehr Jedmowski, Laura Verena Junker-Frohn, Thorsten Kraska, Onno Muller, Patrick Rademske, Christiaan Van Der Tol, Juan Quiros-Vargas, Peiqi Yang, Uwe Rascher

School of Natural Resources: Faculty Publications

Remote sensing-based measurements of solar-induced chlorophyll fluorescence (SIF) are useful for assessing plant functioning at different spatial and temporal scales. SIF is the most direct measure of photosynthesis and is therefore considered important to advance capacity for the monitoring of gross primary production (GPP) while it has also been suggested that its yield facilitates the early detection of vegetation stress. However, due to the influence of different confounding effects, the apparent SIF signal measured at canopy level differs from the fluorescence emitted at leaf level, which makes its physiological interpretation challenging. One of these effects is the scattering of SIF …

Insufficient funding is a major impediment to conservation efforts around the world. In the United States, a decline in hunting participation threatens sustainability of the “user-pay, public benefit” model that has supported wildlife conservation for nearly 100 years, forcing wildlife management agencies to contemplate alternative funding strategies. We investigated support for potential funding options among diverse college students, a rapidly expanding and politically active voting bloc with a potentially powerful influence on the future of conservation. From 2018 to 2020, we surveyed 17,203 undergraduate students at public universities across 22 states. Students preferred innovative approaches to conservation funding, with 72% …

Mapping Heat Vulnerability Index Based On Different Urbanization Levels In Nebraska, Usa, Babak J. Fard, Rezaul Mahmood, Michael Hayes, Clinton M. Rowe, Azar M Abadi, Martha Shulski, Sharon Medcalf, Rachel Lookadoo, Jesse E. Bell

School of Natural Resources: Faculty Publications

Despite similar incidence rates, Heat Vulnerability Index (HVI) in rural areas is under- studied in comparison to urban areas. • The environmental vulnerability variables in rural areas are dissimilar to urban areas, so we applied different variables to calculate them. • We found different organization of socioeconomic variables in calculated HVIs, suggesting separate heat strategies for urbanization levels.

Heatwaves cause excess mortality and physiological impacts on humans throughout the world, and climate change will intensify and increase the frequency of heat events. Many adaptation and mitigation studies use spatial distribution of highly vulnerable local populations to inform heat reduction and …

Declining participation in hunting, especially among young adult hunters, affects the ability of state and federal agencies to achieve goals for wildlife management and decreases revenue for conservation. For wildlife agencies hoping to engage diverse audiences in hunter recruitment, retention, and reactivation (R3) efforts, university settings provide unique advantages: they contain millions of young adults who are developmentally primed to explore new activities, and they cultivate a social atmosphere where new identities can flourish. From 2018 to 2020, we surveyed 17,203 undergraduate students at public universities across 22 states in the United States to explore R3 potential on college campuses …

Determinants Of Water System Management, Caleb White

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Water system management is complex, involving state, local, and federal regulations and impacting people from a wide variety of socioeconomic backgrounds. Systems in the developing and industrialized worlds both face challenges in managing water systems. Much research has been completed regarding associations of water system violations and system factors, and there has been an increased attention to issues of environmental justice – how water system violations affect communities of color, impoverished communities, and rural communities. Currently no studies have focused on the associations between socioeconomic factors and water system management violations. The goal of this research was to ascertain the …
