It Won’T Be Easy, Allison Arkush

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

Interdisciplinary artist Allison Arkush engages a wide range of materials, modalities, and research in her practice. In It Won’t Be Easy, Arkush places and piles her multimedia sculptures throughout the gallery to create installations that overlap ­with her writing and poetry, sometimes layering in (or extending out to) audio and video components. This approach facilitates the probing exploration of prevailing value systems through a flattening of hierarchies among and between humans, the other-than-human, and the inanimate—though no less lively. Her work meditates on and ‘vendiagrams’ things forsaken and sacred, the traumatic and nostalgic. The exhibition title acknowledges that the …

Reflection Types And Students’ Viewing Of Feedback In A First-Year Engineering Course Using Standards-Based Grading, Heidi A. Diefes-Dux, Laura M. Cruz Castro

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: Feedback is one of the most powerful and essential tools for learning and assessment, particularly when it provides the information necessary to close an existing gap between actual and reference levels of performance. The literature on feedback has primarily focused on addressing strategies for providing effective feedback rather than aspects of students’ readiness to engage with feedback. Purpose/Hypothesis: This study investigated whether reflection, as a routine pedagogical intervention grounded in self-regulated learning theory, promotes the frequency with which students view feedback. Design/Method: A quasi-experimental design was employed to examine the relationship between the use of four different reflection types, …

Building Resilience In Ctls: Reflections On Practice, Lisa J. Hatfield, Julie Maxson, Jennifer Marshall Shinaberger, Hanna E. Norton, Cynthia (Cia) H. Demartino, Annette Finley-Crosswhite, Gigi Gokcek

To Improve the Academy: A Journal of Educational Development

What are the qualities of the “now” that make teaching and learning an urgent, if not a moral, imperative? A group of faculty, administrators, and educational developers respond to this question with individual narratives bound together by a common theme of reflective practice in times of crises to help faculty become more resilient in preparing for ongoing upheavals and unexpected crises while pursuing more inclusive communities. Our personal narratives reflect on the subjects of flexibility in the face of crises, technology and ethics, study abroad exposure to ethical challenges, students’ growing anxiety and mental health, modeling metacognition with peers and …

Toward Institutionalizing Successful Innovations In The Academy, Sarah B. Wise, Courtney Ngai, Joel Christopher Corbo, Mark A. Gammon, Jaclyn K. Rivard, Clara E. Smith

To Improve the Academy: A Journal of Educational Development

Due to the “wicked problem” of the Academy’s resistance to innovation, new teaching and learning programs struggle to become integrated into the fabric of the Academy, which slows the uptake of evidence-based practices. This wicked problem is rooted in the lack of slow, intentional mechanisms for cultural change in the Academy. In this article, we analyze the institutionalization journey of the Departmental Action Team (DAT) project, which is a model for slow, intentional change. Over the last four years, partnering with two campus centers for teaching and learning (CTLs) allowed the DAT project to make institutionalization progress.

This analysis is …

UNL Student Research Days Posters, Graduate

The Juan de Fuca plate is subducting beneath the North American plate along the Cascadia Subduction Zone. The CSZ is associated with multiple earthquakes, although compared to other subduction zones, it is less active. Many studies suggest that subduction will cause major mega thrust earthquake in near future, while others oppose this view. This project is focused on the Diebold Knoll on the JdF plate Various geophysical methods will be integrated to determine its origin and tectonic history.

Larval Fish Abundance In The Benthic And Surface Drift Of The Missouri River, Ryan L. Ruskamp

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

Knowledge of the larval fish community of the Missouri River is one of the biggest gaps in fisheries research. The Nebraska Game and Parks Commission has sampled the drift of the Missouri River for many years (1983-2015), but these data have not been compiled into a unified assessment. Therefore, the objectives of this study were to: 1) quantify temporal and spatial aspects of larval fish community composition (richness) and structure (abundance) of the surface drift, 2) quantify associations of larval fish communities of the drift to different discharges of the Missouri River, 3) quantify the larval benthic drift community, and …

Using Field Scale Electrical Data To Understand Real-Time Agricultural Water Delivery, Bradley Dowell

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Areas across the High Plains (Ogallala) Aquifer region are experiencing unsustainable groundwater level declines and impacts to streamflow due to increasing human influence, posing challenges for sustaining future agricultural economies and groundwater resources. State and local agencies manage water using groundwater models, which are not at the same temporal and spatial scale as water management on farms. Well-informed agricultural water usage cannot be achieved without reliable and cost-effective water use at farm scale. Water meters are expensive and rarely installed unless required by the state or other regulatory agency; however, most center pivots have their own power supply, which reports …

A Mixed Methods Case Study: Effects Of Instructors’ Beliefs On Incorporation Of Sustainability Curriculum At A Midwestern University, Anna Oetting

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

The degree to which sustainability is taught is often varied and inconsistent across colleges, departments, and higher education institutions. However, educating students and future generations regarding the different pillars of sustainability, including economic, social, and environmental topics, is increasing in importance and urgency. A mixed methods case study utilized surveys and interviews to investigate why instructors incorporate sustainability, what impacts course incorporation of sustainability, and barriers that instructors face. This study found that instructors’ beliefs regarding the importance of sustainability relate to the extent to which sustainability is incorporated into their curriculum. Topics of sustainability incorporated into a class are …

Remotely Close: An Investigation Of The Student Experience In First-Year Mathematics Courses During The Covid-19 Pandemic, Sawyer Smith

Honors Program: Senior Projects (Public)

The realm of education was shaken by the onset of the COVID-19 pandemic in 2020. It had drastic effects on the way that courses were delivered to students, and the way that students were getting their education at the collegiate level. At the University of Nebraska – Lincoln, the pandemic dramatically changed the way that first-year mathematics courses looked for students. By Spring 2021, students had the opportunity to take their first-year math courses either in-person or virtually. This project sought to identify differences between the two methods of course delivery during the Spring 2021 semester, regarding interaction with peers …

“Any Lady Can Now Learn To Cut Perfect Fitting Dresses”: The Role Of Pattern Drafting Systems In The Production Of Women’S Dress, 1880–1900, Alyssa Smith

Department of Textiles, Merchandising and Fashion Design: Dissertations, Theses, and Student Research

This research conveys findings from my MA thesis research focused on pattern drafting systems for women’s garments developed between 1880 and 1900. The study builds on the seminal work of Claudia Kidwell, who divided these systems into three categories: proportional, hybrid, and direct measure. To date, the study of this textile technology and how it positioned women and sewing in both domestic and professional spheres has received little scholarly attention, but pattern drafting technology transformed the possibilities for pattern creation and proportionate measurements, especially for home sewers. It also aided in the paper pattern and ready-made clothing industries. This research, …

The Effect Of Store-To-Store Energy Transfers On The Global Dynamics Of Aircraft, Guilherme Mainieri Eymael, Keegan J. Moore

UNL Student Research Days Posters, Undergraduate

This study analyzes the energy transfer mechanisms when nonlinear devices (stores) are attached to a linear model airplane. For that, a reduced-order model (ROM) was derived to simulate the first two flexible modes of vibration of the primary structure (aircraft) with one store in each wing. Each store can either be locked or unlocked. When locked, it only contributes as mass-effect, and when unlocked, it adds nonlinearity to the system. Simulations were then performed with either both stores locked, one store unlocked, or both stores unlocked. It was found that the attachment of nonlinear stores in the ROM changes the …

Learning Domain Invariant Information To Enhance Presentation Attack Detection In Visible Face Recognition Systems, Jennifer Hamblin

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Face signatures, including size, shape, texture, skin tone, eye color, appearance, and scars/marks, are widely used as discriminative, biometric information for access control. Despite recent advancements in facial recognition systems, presentation attacks on facial recognition systems have become increasingly sophisticated. The ability to detect presentation attacks or spoofing attempts is a pressing concern for the integrity, security, and trust of facial recognition systems. Multi-spectral imaging has been previously introduced as a way to improve presentation attack detection by utilizing sensors that are sensitive to different regions of the electromagnetic spectrum (e.g., visible, near infrared, long-wave infrared). Although multi-spectral presentation attack …

United States Department of Agriculture Wildlife Services: Staff Publications

Protected areas are intended as tools in reducing threats to wildlife and preserving habitat for their long-term population persistence. Studies on ranging behavior provide insight into the utility of protected areas. Vultures are one of the fastest declining groups of birds globally and are popular subjects for telemetry studies, but continent-wide studies are lacking. To address how vultures use space and identify the areas and location of possible vulture safe zones, we assess home range size and their overlap with protected areas by species, age, breeding status, season, and region using a large continent-wide telemetry datasets that includes 163 individuals …

Economic Consequences Of The Wolf Comeback In The Western United States, Dana Hoag, Stewart W. Breck, Kevin Crooks, Becky Niemiec

United States Department of Agriculture Wildlife Services: Staff Publications

Gray wolves were eradicated from most of the United States in the 1940’s but have made a comeback in parts of their historic range over the last two decades. First reintroduced into the Greater Yellowstone Ecosystem and central Idaho in the mid-1990’s, wolves have subsequently dispersed into at least 7 western states. Coloradoans became the latest state to take interest in bolstering wolf populations, as residents passed a ballot initiative in November 2020 to reintroduce a self-sustaining population of gray wolves by the end of 2023. Conflicts between people in rural areas that might incur costs (such as livestock loss) …

Microbiome Variation Across Populations Of Desert Halophyte Zygophyllum Qatarensis, Abdul Latif Khan, Lucas Dantas Lopes, Saqib Bilal, Sajjad Asaf, Kerri M. Crawford, Venkatesh Balan, Ahmed Al-Rawahi, Ahmed Al-Harrasi, Daniel P. Schachtman

Department of Agronomy and Horticulture: Faculty Publications

Microbial symbionts play a significant role in plant health and stress tolerance. However, few studies exist that address rare species of core-microbiome function during abiotic stress. In the current study, we compared the microbiome composition of succulent dwarf shrub halophyte Zygophyllum qatarensis Hadidi across desert populations. The results showed that rhizospheric and endosphere microbiome greatly varied due to soil texture (sandy and gravel). No specific bacterial amplicon sequence variants were observed in the core-microbiome of bulk soil and rhizosphere, however, bacterial genus Alcaligenes and fungal genus Acidea were abundantly distributed across root and shoot endospheres. We also analyzed major nutrients …
