Active Learning And Student Achievement: A Matter Of Space, Experiences, Or Pedagogy?, Justin Bruner, Rebecca Affoo, Angela M. Dietsch

Department of Special Education and Communication Disorders: Faculty Publications

The goal of this study was to contribute to research on active learning by addressing the problem of disentangling the effects of classroom architecture, student characteristics, and pedagogical design as they relate to student achievement. The study utilized a quasi-experimental design where data was collected on student perceptions of their classroom, their experience in the course, and the pedagogy of the instructor, then analyzed with respect to the course grade. Results indicate that neither student perceptions of the classroom spaces nor the spaces themselves had an impact on course grade, but the pedagogy employed by the instructor and student experiences …

When Science Journalism Is Awesome: Measuring Audiences’ Experiences Of Awe From Reading Science Stories, Asheley R. Landrum, Kristina Janét, Kelsi Opat, Heather Akin

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

In collaboration with professional science journalists, we conducted a national online survey (N = 2,088) to explore facets of awe as potential response states to science journalism and how audiences’ dispositional science curiosity may influence these response states. Our science journalist collaborators identified several “awe-inducing” articles as well as a “business-as-usual” article to use in the survey, and we measured participants’ experiences of awe using the Awe Experience Scale (AWE-S). We replicated the factor structure of the AWE-S and found that participants’ generally experienced greater awe from reading the “awe-inducing” science articles compared to the “business-asusual” one. Only partial support …

From Cropland To Cropped Field: A Robust Algorithm For National-Scale Mapping By Fusing Time Series Of Sentinel-1 And Sentinel-2, Bingwen Qiu, Duoduo Lin, Chongcheng Chen, Peng Yang, Zhenghong Tang, Zhenong Jin, Zhiyan Ye, Xiao Zhu, Mingjie Duan, Hangyu Huang, Zhiyuan Zhao, Weiming Xu, Zuoqi Chen

Architecture Program: Faculty Scholarly and Creative Activity

Detailed and updated maps of actively cropped fields on a national scale are vital for global food security. Unfortunately, this information is not provided in existing land cover datasets, especially lacking in smallholder farmer systems. Mapping national-scale cropped fields remains challenging due to the spectral confusion with abandoned vegetated land, and their high heterogeneity over large areas. This study proposed a large-area mapping framework for automatically identifying actively cropped fields by fusing Vegetation-Soil-Pigment indices and Synthetic-aperture radar (SAR) time-series images (VSPS). Three temporal indicators were proposed and highlighted cropped fields by consistently higher values due to cropping activities. The proposed …

Coping Matters: An Examination Of Coping Among Black Americans During Covid-19, Caitlin M. Mercier, Dena M. Abbott, Michael S. Ternes

Department of Educational Psychology: Faculty Publications

Using a critical race theory framework and a convergent mixed-method design, this study examined the relationship between coping with stress and psychological distress among Black U.S. Americans (N = 155) during the COVID-19 pandemic in the context of race-based stressors (e.g., anti-Black racism). Path analysis revealed mixed support for hypotheses; avoidant coping was positively related to all measured facets of psychological distress, whereas socially supported coping was associated with none. Self-sufficient coping was negatively associated with only depressive symptoms. Qualitative analysis revealed four salient themes: (a) Race and the COVID-19 Pandemic, (b) Complex Pandemic Related Changes to Life, (c) …

Department of Communication Studies: Faculty Publications

Objective: To understand turning points (TPs) in the development of positive stepparent–stepchild communication and relationships.

Background: Scholars stress the importance of communication in co-constructing healthy stepparent–stepchild relationships. The researchers focused on positive stepparenting via understanding transformational turning point (TP) events across time. Research questions explored how stepparents with an overall positive relationship with a stepchild characterize TPs and the discursive constructions of the stepparent role.

Method: The team analyzed 877 pages of data from 37 in-depth interviews with stepparents who described self-identified TP events, reflected in visual graphs of 279 TPs.

Results: Data were coded into 11 TP types, focused …

Pants On Fyre: Parasitic Masculinity And The Fyre Festival Documentaries, Kristen Hoerl, Casey Ryan Kelly

Department of Communication Studies: Faculty Publications

The documentaries Fyre Fraud and FYRE: The Greatest Party that Never Happened recount the fraudulent and imprudent decision-making process that led up to the ill-fated Fyre Fest. These documentaries represent the music festival’s failure through depictions of white masculinity that seek parasitic attachment and proximity to the hegemonic ideal of masculine authority in the neoliberal marketplace. We argue that these movies map the operations of an imitative form of white masculine subjectivity that thrives in precarity, even as they recuperate the status of late-stage neoliberalism by symbolically removing parasitic masculinity from the neoliberal social order that it feeds on.

Production Cow-Calf Responses From Perennial Forage-Based And Integrated Beef-Cropping Systems, Zac E. Carlson, Levi Mcphillips, Galen E. Erickson, Mary E. Drewnoski, Jim C. Macdonald

Department of Animal Science: Faculty Publications

An experiment was conducted to measure production responses of an alternative cow-calf production system integrated into a cropping system without access to perennial forage compared to a traditional cow-calf system utilizing perennial forage. Multiparous, cross-bred beef cows (n = 160; average age = 6.2 ± 2.8 yr) were utilized in a randomized complete block experimental design and unstructured treatment design. Upon initiation, cows were blocked by age and stratified by source, assigned randomly to one of two production systems, each with four replicates (n = 20 cows/replicate). Once allotted to their treatment groups, cows remained in their experimental units for …

Evaluation Of A Novel Computer Vision-Based Livestock Monitoring System To Identify And Track Specific Behaviors Of Individual Nursery Pigs Within A Group-Housed Environment, Ty B. Schmidt, Jessica M. Lancaster, Eric T. Psota, Benny E. Mote, Lindsey E. Hulbert, Aaron Holliday, Ruth Woiwode, Lance Perez

Department of Animal Science: Faculty Publications

Animal behavior is indicative of health status and changes in behavior can indicate health issues (i.e., illness, stress, or injury). Currently, human observation (HO) is the only method for detecting behavior changes that may indicate problems in group-housed pigs. While HO is effective, limitations exist. Limitations include HO being time consuming, HO obfuscates natural behaviors, and it is not possible to maintain continuous HO. To address these limitations, a computer vision platform (NUtrack) was developed to identify (ID) and continuously monitor specific behaviors of group-housed pigs on an individual basis. The objectives of this study were to evaluate the capabilities …

An Expert-Curated Global Database Of Online Newspaper Articles On Spiders And Spider Bites, Stefano Mammola, Laura Segura-Hernández, Et Al.

School of Biological Sciences: Faculty Publications

Mass media plays an important role in the construction and circulation of risk perception associated with animals. Widely feared groups such as spiders frequently end up in the spotlight of traditional and social media. We compiled an expert-curated global database on the online newspaper coverage of human-spider encounters over the past ten years (2010– 2020). This database includes information about the location of each human-spider encounter reported in the news article and a quantitative characterisation of the content—location, presence of photographs of spiders and bites, number and type of errors, consultation of experts, and a subjective assessment of sensationalism.

Localization Effects And Anomalous Hall Conductivity In A Disordered 3d Ferromagnet, Paul M. Shand, Y. Moua, G. Baker, Shah R. Valloppilly, Pavel V. Lukashev, Parashu Kharel

Nebraska Center for Materials and Nanoscience: Faculty Publications

We have prepared the Heusler alloy CoFeV_0.5Mn_0.5Si in bulk form via arc melting. CoFeV_0.5Mn_0.5Si is ferromagnetic with a Curie temperature of 657 K. The longitudinal resistivity exhibits a minimum at 150 K, which is attributable to competition between quantum interference corrections at low temperatures and inelastic scattering at higher temperatures. The magnetoresistance (MR) is positive and nearly linear at low temperatures and becomes negative at temperatures close to room temperature. The positive MR in the quantum correction regime is evidence of the presence of the enhanced electron interaction as a contributor to …

Revisiting Clickers: In-Class Questions Followed By At-Home Reflections Are Associated With Higher Student Performance On Related Exam Questions, Dana L. Kirkwood-Watts, Emily K. Bremers, Emily Robinson, Kathleen R. Brazeal, Brian A. Couch

School of Biological Sciences: Faculty Publications

Clicker questions are a commonly used active learning technique that stimulates student interactions to help advance understanding of key concepts. Clicker questions are often administered with an initial vote, peer discussion, and a second vote, followed by broader classroom explanation. While clickers can promote learning, some studies have questioned whether students maintain this performance on later exams, highlighting the need to further understand how student answer patterns relate to their understanding of the material and to identify ways for clickers to benefit a broader range of students. Systematic requizzing of concepts during at-home assignments represents a promising mechanism to improve …

Developing And Evaluating A Pollination Systems Knowledge Assessment In A Multidisciplinary Course, P. Citlally Jimenez, Doug Golick, Brian A. Couch, Jenny Dauer

Department of Entomology: Faculty Publications

Background: Although pollinators play an integral role in human well-being, their continued global decline reflects the need to provide and evaluate general pollinator knowledge to promote their conservation. Enhancing learners’ understanding of the complexity inherent in pollination systems within the science classroom may help them make more informed decisions regarding pollinator conservation actions. By measuring conceptual understanding of pollination systems, science educators can identify learners’ knowledge needs and inform their teaching in science classrooms. Based on previously developed theoretical frameworks describing pollination systems knowledge, we created and evaluated a new instrument to assess pollination systems and conservation actions knowledge. The …

Federal Experimentation Through State Constitutional Initiatives, Robinson Woodward-Burns

Nebraska Law Review

This Article describes how reformers, who were often blocked by Congress, were able to achieve their policy aims through state constitutional initiatives. The Constitution grants the state and federal governments shared, concurrent constitutional powers. On concurrent powers matters, reformers might attempt either state or federal constitutional revision. Reformers might petition Congress for a federal amendment to dictate national policy or to bind or homogenize the states. But federal amendments rarely clear the two-thirds supermajorities needed to pass Congress or the three-quarters supermajorities needed for subsequent ratification by the states. Of the 11,790 proposed federal amendments, only thirty-three have been passed …

Play Like A Girl: Bostock, Title Ix’S Promise, And The Case For Transgender Inclusion In Sports, Rachel Tomlinson Dick

Nebraska Law Review

State-level legislation focused on the transgender1 community has exploded over the last several years.2 Proposed laws mandating the exclusion of transgender individuals from specific sectors of society have been increasingly focused on trans children and youth.3 In 2021, legislatures in thirty-one states introduced bills that would prohibit transgender student-athletes from taking part in school sports in a manner consistent with their gender identities.4 Eight of those states ultimately passed laws barring young women who are trans from participating in girls’ and women’s sports programs sponsored by federally- funded schools.5 Idaho enacted a bill that blocked transgender women and girls from …

Law And Liberty On The Moon, Frans Von Der Dunk

Space, Cyber, and Telecommunications Law Program: Faculty Publications

As on Earth, so in outer space . .

Most of those participating in humankind’s venturing into outer space, in particular to the extent of establishing settlements there and thereby providing for a second home for humanity, would hope or even assume that humankind in so doing might be able to avoid the sometimes rather bloody developments that accompanied settlement in far-away territories on Earth. However, at least in the legal area, with a view to its role as providing not only justice and fairness but also predictability and foreseeability, logic dictates that terrestrial laws and experiences of these laws …

Penal Practices: An American And Norwegian Comparison, Anne Martinez

Nebraska College Preparatory Academy: Senior Capstone Projects

A lot is known about prison systems around the world, especially in bigger countries. However, not much is publicly known about the inner workings of the prisons themselves. These differences range from their incarceration rates, their environments, and their health care. This research will explore those striking differences between the Kriminalsomsorgen, Norway’s correctional facility, and the United States penal system. Both of these systems have very different approaches to justice seeing as how one emphasizes retribution while the other emphasizes rehabilitation. Each section of this research will go on to discuss how the United States is severely lacking in these …

Don’T Forget To Wash! Water, Sanitation, And Hygiene Among Zambian Students, Katie Schmitz

NUTR/GLST 498b: Global Research Experiences in Nutrition and Health

Introduction: Water, sanitation, and hygiene practices in sub-Saharan Africa, including Zambia, have not met the Millennium Development Goals (MDGs) and remain inadequate to improve the overall health and wellbeing of most populations.

Methods: Survey research, interviews, WASH observations, and anthropometric assessment were conducted between May-June 2022 on 6-7th grade students within 6 Zambian schools.

Results: While hygiene knowledge was prominent, and handwashing stations and pit latrines were available, schools rarely supplied soap or toilet paper. Diarrheal and respiratory diseases were common and water shortages remain problematic with some students traveling long distances to reach a water source.

Discussion: As in …

Wetlandology: A Kid's Book About Wetlands, Grace Gaard, Ted Lagrange

Nebraska Game and Parks Commission: Publications

What is a Wetland? You might think that any land that is wet would be a wetland, right? But if the occurrence of water was the only thing that made a wetland a wetland, then deeper parts of oceans and rivers would be considered wetlands. And we know that is not true! So, what actually makes a wetland a wetland? Wetlands are defined by three things:

1. Soil

2. Plants

3. Hydrology

Wetlands are spread throughout Nebraska, but it is useful to identify some of the larger wetland complexes in the state. Wetlands can be found everywhere! All rivers and …

¿Aviso O Alerta? Developing Effective, Inclusive, And Consistent Watch And Warning Translations For U.S. Spanish Speakers, Joseph E. Trujillo-Falcón, América R. Gaviria Pabón, Joseph T. Ripberger, Abby Bitterman, Jonathan B. Thornton, Mackenzie J. Krocak, Sean R. Ernst, Estilita Cassiani Obeso, John Lipski

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

Spanish-speaking populations in the United States are more vulnerable in disaster contexts due to inequities, such as language barriers, that prevent them from receiving life-saving information. For the past couple of decades, governmental organizations have addressed these issues by translating weather watches, warnings, and advisories into Spanish. Previous studies suggest that these Spanish translations do not communicate the same level of urgency as their English counterparts. To identify whether these translated products result in inequities between English and Spanish speaker reception and comprehension of forecast information, we asked a representative sample of U.S. English (n = 1,550) and Spanish (n …

An Overview Of Integrated Pest Management In Greenhouse Systems, Kateri Cavanagh

Department of Entomology: Distance Master of Science Projects

Greenhouses are technological advancements that have existed since the first century. Human life and the field of agriculture have greatly improved with their invention. However, greenhouses come with their own set of challenges. One of the biggest issues with greenhouse systems is the presence of large pest populations. This is due to the ample food and water supply along with the relative stability of greenhouses. Pests in greenhouses are usually dealt with through the application of chemical pesticides. However, integrated pest management (IPM) is gaining traction for use in greenhouse systems. This overview will cover the history of greenhouses and …
