Fragments Of The Dark: Essays On Heritage, Anxiety, And Spirit, Nicholas Diaz

Department of English: Dissertations, Theses, and Student Research

“I am the war my family forgot to mention.” With these words from my essay, “My Parents Never Taught Me About My Ancestors,” I stake my position in the struggle for happiness. In a series of five experimental essays, I aim to reflect upon my assimilated white, working-class upbringing in the US Midwest and the emptiness with which it has left me. Deploying fragmentary essay forms, elements of memoir, question-and-answer, quotation, prayer, and other devices, I hope to pose destabilizing questions about our understandings of whiteness, masculinity, ancestry, and faith. Questions which, I hope, can help us (particularly those of …

"The Blackbird Girls": Designing A Four Week Novel Unit For Upper Elementary And Middle Grades, While Navigating Teaching In An Ever-Changing Digital World, Ashley Kallhoff

Honors Program: Senior Projects (Public)

As a future teacher in an increasing digital world, I wanted to create an online curriculum I could use in my future classroom, students all over the world could use, and other teachers could implement in their own classroom. Taking all of this into consideration, I have designed a digital four-week, 20-day, novel unit for upper elementary and middle grades with social studies and language arts dual focus. The novel I chose was a historical fiction young adult text titled The Blackbird Girls by Anne Blankman. This novel follows the story of two young girls, one that is Jewish and …

An Exploratory Study Of How Measuring Knowledge-In-Use Adds Value Beyond Static Knowledge Measures, Julie Dwyer, Rachel E. Schachter, Alessandra E. Ward

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

Research-supported knowledge about how children develop language is considered foundational for high-quality instruction and as such, measuring and developing teachers’ knowledge has been emphasized across the field of early childhood. However, there is a critical gap in understanding how this static knowledge gained through pre-service and in-service experiences is connected to enacted practice. To address this, we compared teachers’ static knowledge regarding language development as assessed via a traditional paper and pencil measure with their knowledge used in-the-moment during language interactions with children via stimulated recall interviews. Ten educators from a variety of early childhood programs completed the surveys and …

How Gender And Primary Language Influence The Acquisition Of Economic Knowledge Of Secondary School Students In The United States And Germany, Roland Happ, Susanne Schmidt, Olga Zlatkin-Troitschanskaia, William Walstad

Department of Economics: Faculty Publications

Economics has become an essential component of secondary school curricula in many countries as a result of the growing awareness that young adults need fundamental economic knowledge to manage their personal finances. Accordingly, an increasing number of comparative studies are being conducted of commonalities and differences in students’ economic knowledge and its most decisive influencing factors within and across countries. In this study, we compare the performance of secondary school students in the United States (N = 3517) and Germany (N = 983) on the fourth version of the Test of Economic Literacy. We investigate two personal characteristics that have …

Two Qtls Govern The Resistance To Sclerotinia Minor In An Interspecific Peanut Ril Population, Melina H. Rosso, Francisco J. De Blas, Alicia N. Massa, Claudio Oddino, Damian F. Giordano, Jose G. Seijo, Renee S. Arias, Juan H. Soave, Sara J. Soave, Mario I. Buteler, Marina Bressano

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

Sclerotinia blight is a soilborne disease caused by Sclerotinia minor Jagger and can produce severe decrease in yield. Cultural management strategies and chemical treatment are not completely effective; therefore, growing peanut-resistant varieties is likely to be the most effective control method for this disease. Sclerotinia blight resistance has been identified in wild Arachis species and further transferred to peanut elite cultivars. To identify the genome regions conferring Sclerotinia blight resistance within a tetraploid genetic background, this study evaluated a population of recombinant inbred lines (RIL) with introgressed genes from three wild diploid species: A. cardenasii, A. correntina, and A. batizocoi. …

Global Three-Dimensional Water Vapor Feature-Tracking For Horizontal Winds Using Hyperspectral Infrared Sounder Data From Overlapped Tracks Of Two Satellites, Amir Ouyed, Nadia Smith, Xubin Zeng, Thomas Galarneau Jr., Hui Su, Ross D. Dixon

Department of Earth and Atmospheric Sciences: Faculty Publications

The lack of measurements of three-dimensional (3D) distribution of horizontal wind vectors is a major challenge in atmospheric science. Here, we develop an algorithm to retrieve winds for nine pressure levels at 1° grid spacing from 70°N to 70°S. The retrieval is done by tracking water vapor from the hyperspectral Cross-track Infrared Sounder aboard two polar satellites (NOAA-20 and Suomi-NPP) that have overlapped tracks separated by 50 min. We impose a gross error check by flagging retrievals that are too different from ERA-5 reanalysis. Testing the algorithm for the first week of January and July 2020 indicates that our algorithm …

The Uncertain Fate Of L.B. 753 Under Article Vii, Section 11 Of The Nebraska Constitution’S No-Aid Provision, Anthony B. Schutz

Nebraska Law Bulletin (Selected Issues)

The Nebraska Legislature is considering a bill–Legislative Bill 753 (L.B. 753)–that would provide a non-refundable, 5-year carry-over tax credit for donations to qualifying scholarship-providing organizations. To qualify, the scholarship organization must provide qualifying education scholarships. Those qualifying education scholarships must be used to pay tuition and fees at a qualifying school. Qualifying schools are “any nongovernmental, privately operated elementary or secondary school located in this state.” The state administers the issuance of the tax credits through a program that keeps the budgeted caps in place. The program starts with a $25 million cap that gradually expands to $100 million if …

Economics Of Deficit Irrigation Utilizing Soil Moisture Probes In The Western Corn Belt, Emily O’Donnell, Lia Nogueira, Cory Walters, E Wesley F. Peterson, Suat Irmak

Department of Agricultural Economics: Faculty Publications

Effective irrigation management is critical for future food supplies and the prosperity of producers engaged in irrigation production. Through a deficit irrigation field experiment, we determine the financial impact on producers caused by changing irrigation costs, corn prices, extreme weather events, and restricting irrigation levels. Results suggest that the optimal economic strategy within our constrained optimization model is to fully irrigate, with the economic impact highly dependent on commodity prices, restriction level, and irrigation costs. The greatest economic losses caused by irrigation restrictions come from decreases in yield. Some simulations resulted in negative profits, indicating that a switch to alternative …

Teaching With Collective Resilience During Covid-19: Korean Teachers And Collaborative Professionalism, Minseok Yang, Yujin Oh, Sunbin Lim, Taeyeon Kim

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

This study applies system-focused resilience and collaborative professionalism to examine how teachers in Korea collectively developed resilience and transformed teaching during COVID-19. Using qualitative data from seven individual interviews and four focus groups, we found Korean teachers navigated complex challenges (rapidly changing policies, online teaching, exacerbated learning gaps, and excessive social pressure) and utilized contextual resources (collective autonomy and flexibility, solidity and solidarity, and collective responsibility) to develop strategies (collaborative inquiry, timely communication, and envisioning the future of schooling). The study extends teacher resilience toward more collective and communal, from the individual level, by linking resilience to collaborative systemic changes. …

Eeg Decoding Of Finger Numeral Configurations With Machine Learning, Roya Salehzadeh, Brian Rivera, Kaiwen Man, Nader Jalili, Firat Soylu

Department of Psychology: Faculty Publications

In this study, we used multivariate decoding methods to study processing differences between canonical (montring and count) and noncanonical finger numeral configurations (FNCs). While previous research investigated these processing differences using behavioral and event-related potentials (ERP) methods, conventional univariate ERP analyses focus on specific time intervals and electrode sites and fail to capture broader scalp distribution and EEG frequency patterns. To address this issue a supervised learning classifier—support vector machines (SVM)—was used to decode ERP scalp distributions and alpha-band power for montring, counting, and noncanonical FNCs (for integers 1 to 4). The SVM was used to test whether the numerical …

‘Chinese Virus’: A Critical Discourse Analysis Of Anti-Asian Racist Discourse During The Covid-19 Pandemic, Peiwen Wang, Theresa Catalano

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

Since the emergence of COVID-19, researchers have documented an increase in cases of anti-Asian racism and hate crimes. Research shows a possible connection between the ‘Chinese virus’ discourse of the Trump administration and violence in society (Arora and Kim 2020:387). Drawing from critical discourse studies we explore 2,071 comments from one YouTube video which documents anti-China rhetoric by the Trump administration in order to understand the underlying strategies commenters relied on in their reproduction and defence of this discourse. Findings show the trickle-down influence of Trump’s discourse on YouTube commenters, but also ways in which social media created a platform …

Fog Of War: How The Ukraine Conflict Transformed The Cyber Threat Landscape, Threat Analysis Group (Tag), Mandiant, Google Trust & Safety

Copyright, Fair Use, Scholarly Communication, etc.

One year ago, Russia invaded Ukraine. Since then, tens of thousands of people have been killed, millions of Ukrainians have fled and the country has sustained tens of billions of dollars worth of damage. Importantly, this marks the first time that cyber operations have played such a prominent role in a world conflict.

Since the war began, governments, companies, civil society groups, and countless others have been working around the clock to support the Ukrainian people and their institutions. At Google, we support these efforts and continue to announce new commitments and support to Ukraine. This includes a donation of …

Effects Of High-Pressure Processing On Cooked Color And Eating Qualities Of Dark-Cutting Beef, Cole Reesman, Gary Sullivan, Mary-Grace C. Danao, Gretchen G. Mafi, Morgan Pfeiffer, Ranjith Ramanathan

Department of Animal Science: Faculty Publications

High meat pH leads to an undercooked or an abnormal pink appearance in fully-cooked product. High-pressure processing (HPP) promotes protein denaturation. The objective was to evaluate the effects of HPP on cooked steak color and sensory attributes of dark-cutting beef. USDA Choice (mean pH = 5.5) and dark-cutting (mean pH = 6.3) strip loin sections were vacuum packaged and treated with 0 (no HPP), 300, 450, and 600 MPa of pressure for 90 s using chilled water. Steaks were randomly assigned to measure external cooked color, Warner- Bratzler shear force, and trained sensory panel. Applying 300 MPa of pressure improved …

Inclusive Music Teacher Education: Valuing Breadth And Diversity Through Authentic Immersive Experiences, Rhonda J. Fuelberth, Robert H. Woody

Glenn Korff School of Music: Faculty Publications

In this report of self-study research, we share the insights we have gained working together at our institution to make undergraduate music teacher education more inclusive of how people naturally do music, focusing on three program features. First, we explain how our program affirms composition as a primary form of musicianship, similar to the status commonly given to performance. Second, we describe a vernacular music making experience in which our music education students learn to play “rock band” instruments, engage in songwriting, and explore being expressive in the styles of music personally favored by themselves and their future students. Third, …

Role Of Social Determinants Of Health In Differential Respiratory Exposure And Health Outcomes Among Children, Jagadeesh Puvvula, Jill A. Poole, Yeongjin Gwon, Eleanor G. Rogan, Jesse E. Bell

School of Natural Resources: Faculty Publications

Background Attributes defining the Social Determinants of Health (SDoH) are associated with disproportionate exposures to environmental hazards and differential health outcomes among communities. The dynamics between SDoH, disproportionate environmental exposures, and differential health outcomes are often specific to micro-geographic areas.

Methods This study focused on children less than 20 years of age who lived in Douglas County, Nebraska, during 2016–2019. To assess the role of SDoH in differential exposures, we evaluated the association between SDoH metrics and criteria pollutant concentrations and the association between SDoH and pediatric asthma exacerbations to quantify the role of SDoH in differential pediatric asthma outcomes. …

Moctezuma Entre Bambalinas, Isabel Bargalló, Montserrat Bargalló

Tejiendo imágenes. Homenaje a Victòria Solanilla Demestre

Resumen: De los muchos personajes históricos y míticos que ha aportado América a la cultura, uno de los más conocidos y – al mismo tiempo – desconocidos es Moctezuma Xocoyotzin, el tlatoani reinante en México-Tenochtitlan a la llegada de Cortés, y es, sin duda alguna, un héroe tan digno de la lírica como Ulises, Eneas o Julio César. Por este motivo, durante el siglo xviii se compusieron un número muy importante de óperas dedicadas al soberano mexica, para un público algo cansado de los libretos relacionados con la mitología grecorromana y los dramas medievales. En este artículo presentamos una de …

Video Tools In Pediatric Goals Of Care Communication: A Systematic Review, Caitlin M. Nalda, Megan L. Mcsherry, Cynthia M. Schmidt, Marie L. Neumann, Renee D. Boss, Meaghann S. Weaver

Department of Communication Studies: Faculty Publications

Medical advancesmean a growing array of interventions, therapies, and technologies are available to support care for children with chronic and serious conditions. Some of these approaches are supported by robust data drawn from populations that perfectly reflect an individual patient's physiologic, psychologic, and social situation. But much more often, clinicians and families face decisions in the context of some—or much—uncertainty about whether the intervention will do a child more harm than good. This is particularly true for seriously ill children with a limited lifespan— whether the child is a neonate born with a life-threatening brain anomaly or an adolescent with …

Serving Our Communities: Leveraging The Honors College Model At Two-Year Institutions, Eric Hoffman, Victoria M. Bryan, Dan Flores

National Collegiate Honors Council Monographs: Chapters

Honors colleges at two-year institutions play a uniquely important role in twenty-first century higher education by providing additional opportunities, services, and programming that support greater outcomes for the community, especially for those members of underrepresented and underserved populations. Two-year institutions may wonder how the honors college structure could be valuable, particularly when honors programs are already well established, recognized, and understood among the faculty and staff as providing opportunities for students and supported by administration. Honors colleges can give honors a seat at the table in deans councils, budgetary discussions, campus planning, and curriculum development processes, which in turn allows …

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

Introduction: Globally, 27 million female refugees of reproductive age are subjected to numerous socio-ecological factors that increase their risks of mental health issues, especially during the postpartum period. This study seeks to explore Syrian refugee mothers’ experiences and perceptions of postpartum depression.

Methods: We used a qualitative phenomenological approach to interview purposively sampled typical postpartum Syrian mothers living in informal camps in Lebanon to evaluate their maternal mental health perceptions, coping strategies, and help-seeking practices.

Results: Results revealed three major themes: conceptualizing maternal depression as extraordinary and ordinary, cultural perceptions of mental health help-seeking, and coping with negative emotions.

Discussions: …

Why School Choice Is Necessary For Religious Liberty And Freedom Of Belief, Richard F. Duncan

Nebraska College of Law: Faculty Publications

The government school monopoly for funding K–12 education creates a coercive system that commandeers a captive audience of impressionable children for inculcation in secular ideas, beliefs, and values concerning matters of truth, moral character, culture, and the good life. The brutal bargain imposed on parents by this monopoly requires them to choose between the single largest benefit most families receive from state and local governments and educating their children in a curriculum that is consistent with the preferred educative speech of the parents. To choose the latter is to sacrifice hundreds of thousands of dollars of tax-funded support for K–12 …

Margaret Of Anjou: Passionate Mother, Carole Levin

Department of History: Faculty Publications

Margaret of Anjou, who married Henry VI of England in 1445 when she was fifteen years old, was the mother of one son. This child became the most important factor in Margaret’s life. Born in 1430, Margaret’s parents were René, Duke of Anjou, and Isabelle, daughter and heir of Charles II, Duke of Lorraine. She was the niece of Charles VII of France’s wife, Marie of Anjou. Her father’s unsuccessful efforts to expand his holdings meant he was away for much of Margaret’s childhood. As a result, she spent much time with her mother Isabelle and her grandmother, the formidable …

Decline Is Not Inevitable: Changes In Science Identity During The Progression Through A U.S. Middle School Among Boys And Girls, Julia Mcquillan, Patricia Wonch Hill, Joseph C. Jochman, Grace Kelly

Worlds of Connections Resources

In the United States, science capital is important for navigating many aspects of life. Yet during middle school, science interest declines more for girls than boys. It is unclear, however, whether science identity also declines during the middle school years and if there are differences by gender. The authors advance prior research by modeling changes in science identity and associations with changes in identity-relevant characteristics using growth curve analyses on four waves of data from 760 middle school youth. For girls and boys, science identity changes over time; about 40 percent of the variance is within-person change, with the remainder …
