Digitally-Mediated Practices Of Geospatial Archaeological Data: Transformation, Integration, & Interpretation, Heather Richards-Rissetto, Kristin Landau

Department of Anthropology: Faculty Publications

Digitally-mediated practices of archaeological data require reflexive thinking about where archaeology stands as a discipline in regard to the ‘digital,’ and where we want to go. To move toward this goal, we advocate a historical approach that emphasizes contextual source-side criticism and data intimacy—scrutinizing maps and 3D data as we do artifacts by analyzing position, form, material and context of analog and digital sources. Applying this approach, we reflect on what we have learned from processes of digitally-mediated data. We ask: What can we learn as we convert analog data to digital data? And, how does digital data transformation impact …

Experimental Evaluation Of Self-Expandable Metallic Tracheobronchial Stents, Yanli Wang, Pengfei Dong, Jingyao Ke, Xiang Shen, Zongming Li, Kewei Ren, Xinwei Han, Linxia Gu

Department of Mechanical and Materials Engineering: Faculty Publications

The self-expandable metallic stents have been widely used in tracheobronchial obstruction or fistulation, including the J-shaped and Y-shaped stents, named after the shape of the branch-stem junction of the stent. However, there is scarce data on the mechanical performance of these tracheobronchial stents, which is essential for optimal stent implantation. In this work, eight self-expandable metallic tracheobronchial stents in three types (i.e., straight, J-shaped, and Y-shaped), with or without cover, were characterized. The compression resistance of the stems was investigated through both compression and indentation tests. The bending resistance of the branches in the J-shaped and Y-shaped stents was assessed …

Modeling Irrigation Behavior In Groundwater Systems, Timothy Foster, Nicholas Brozovic, Adrian P. Butler

Daugherty Water for Food Global Institute: Faculty Publications

Integrated hydro-economic models have been widely applied to water management problems in regions of intensive groundwater-fed irrigation. However, policy interpretations may be limited as most existing models do not explicitly consider two important aspects of observed irrigation decision making, namely the limits on instantaneous irrigation rates imposed by well yield and the intraseasonal structure of irrigation planning. We develop a new modeling approach for determining irrigation demand that is based on observed farmer behavior and captures the impacts on production and water use of both well yield and climate. Through a case study of irrigated corn production in the Texas …

Vocabulary Instruction: Impacts Of Using A Science Notebook In A Dual Language Setting To Teach Science Vocabulary And Content, Manuel Andazola

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

Language learners and students in general often struggle to close the achievement gap in monolingual schools because they lose academic content due to lack of vocabulary. To combat this issue, programs such as dual language schools have been introduced and have gained popularity due to their ability to help students keep learning academic content in their native language while becoming literate in the second language and also maintaining literacy in the content areas. Although these programs offer different instruction models and teaching techniques that teachers are implementing to improve science literacy, many teachers still struggle to find creative and effective …

Tiny Houses In Metropolitan Areas Of Nebraska: Seasonal Or Permanent Living Environments, Michele L. Hybner

Interior Design Program: Student Creative Activity

This study is designed to determine if tiny houses offer a viable seasonal and/or permanent living environment for Nebraska residents. Two objectives are used to assess the viability of tiny housing in this Midwestern state. The first analyzes the economics (demand, supply, and cost) of tiny housing in metropolitan areas of Nebraska. The second identifies barriers to occupancy of tiny houses in the state. The results of this research are significant because tiny housing presents a means to address the state’s need for more affordable housing options available to Nebraska residents. At the time of this study, 11.4% of Nebraska’s …

The Impacts Of Family Stem Events For Young Children On Parents' Perceptions In A Rural Remote School, Cheyenne Jeffers

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

STEM education is an interdisciplinary approach to creating learning experiences, preparing the children of today to become the workforce and global citizens of a digital tomorrow. Young children are natural explorers of their world, participating in STEM learning through real world experiences. Public and parental misconceptions are hurdles to implementing STEM learning with young children. Many believe young children are not capable of participating in STEM learning and should be taught foundational skills first. On the contrary, STEM learning should be a priority in the educational environment of young children, most beneficially combining efforts at home as well as at …

Influence Of Stem Lessons On Critical Thinking, Brooke Waddell

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

The study of science, technology, engineering, and math (STEM) is leading educators into a new world of teaching. The classroom roles have been reversed and students are now in charge of their own learning. Students are learning how to engineer and solve real-world problems through critical thinking. Integrated STEM lessons are teaching students to use their prior knowledge across subject areas to prepare themselves for the workforce needed in the 21^st century. This study was conducted in a rural second grade classroom with the number of students ranging from 16 to 21. Throughout this study qualitative data was collected. …

Hands-On, Guided Inquiry Science Investigation And Science Vocabulary Acquisition In A Rural Elementary School, Jennifer Mulder

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

Much research has been done to show how inquiry science instruction and inquiry student investigation provide students with hands-on experiences to effectively learn science content in the classroom. Additionally, many methods to efficaciously teach students vocabulary has been thoroughly investigated. However, not much research has been done to study what effect hands-on, guided inquiry science investigation has on student content vocabulary acquisition. Within one rural classroom, fourth graders engaged in hands-on, guided inquiry investigation, and then vocabulary words were explicitly taught and discussed. After that, students practiced the vocabulary words in a variety of ways in pairs and as a …

Assessment And Engagement Strategies For Stem, Aaron Rohde

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

In this study, I looked at how does student engagement change when a certain assessment is announced prior to a unit. This study looks at what different assessment levels have been researched to accomplish and how to utilize that to our advantage. I researched how does student engagement change when STEM projects are introduced in a 5th grade classroom. It is the role as educators to work towards providing our students with the opportunities to express their levels of knowledge and to show students what they have achieved. This study looks at what I found to be important about STEM …

How Vocabulary Notebooks Change Student Knowledge Of Science Concepts And Vocabulary, Justin Wheeler

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

This study was conducted to determine the effect that an explicit vocabulary strategy, the use of vocabulary notebooks, may have on students in an upper elementary science classroom. The study was conducted in a small mid-western town of approximately 14,000 people in an elementary school with approximately 415 students. The study was conducted in a science classroom of fifth-grade students in which the primary investigator was the teacher.

Department of Educational Administration: Dissertations, Theses, and Student Research

Skills gaps in the workforce are a common conversation in the current value proposition of higher education. Colleges are expected to help students prepare for a world-class workforce while maintaining the integrity of the academic mission. Employers have similar but different opinions on the preparation of college graduates. This exploratory study took an in-depth look at the perceptions of sixteen employers in a region of the Midwest on questions about the perception of hiring managers about the skills gap in the workforce. Questions focused on work readiness, common challenges, and opportunities that exist to combat these hiring challenges. The themes …

Enhancing Self-Monitoring With Differential Negative Reinforcement Of Alternative Behavior For Increasing Students’ Writing Production, Meghann Torchia

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

Writing is a difficult task for many students who find it aversive, and who attempt to escape the task. Self-monitoring and differential negative reinforcement of alternative behavior (DNRA) are two approaches that have been shown to improve quantity of performance, but no studies were found that combined the two methods to determine whether they are more effective in combination than in isolation. The purpose of the present study was to evaluate the effectiveness of using DNRA to enhance self-monitoring for increasing writing productivity using a multiple probe, across participants, design. Number of words and number of sentences were measured. For …

“Against The Good Widdow No Harme We Doe Know:” Examining Aristocratic And Gentry Widows’ Roles And Influence In England From 1500–1650, Alyson D. Alvarez

Department of History: Dissertations, Theses, and Student Research

This dissertation explores how English aristocratic and gentry women utilized their widowhoods to actively craft their personal image as well as influence and alter their communities. Free from the common law principles of coverture, English widows gained new legal autonomy. Additionally, many affluent women received substantial inheritances at the deaths of their husbands thus providing them with the financial freedom.

While widowhood offered English women new independence, it was also accompanied by a multitude of expectations. Sixteenth and seventeenth century authors and scholars developed and perpetuated specific conduct deemed appropriate for widows. The behaviors for created for widowed women contributed …

Wyandot, Shawnee, And African American Resistance To Slavery In Ohio And Kansas, Diane Miller

Department of History: Dissertations, Theses, and Student Research

From the colonial period, enslaved Africans escaped bondage. Colonial records and treaties reveal that they often sought refuge with Indian tribes. This resistance to slavery through escape and flight constituted the Underground Railroad. As European colonies developed into the United States, alliances of subaltern groups posed a threat. Colonizers and settlers aimed to divide and control these groups and arrived at the intertwined public policies of African chattel slavery and Indian removal. Tribal abolitionism and participation in the Underground Railroad was more pronounced than scholars have recognized and constituted an important challenge to the expansion of slavery.

Is This What You Wanted?: Expectations, Choice, And Rhetorical Agency In Composition, Caitlin C. Leibman

Department of English: Dissertations, Theses, and Student Research

Choices are a given in rhetorical education, but composition has not given enough attention to the relationship between choices and students’ experiences of rhetorical agency. This dissertation uses expectations as an entry point and choices as a unit of analysis to explore how students navigate and understand their decision-making processes during a single composition project. Drawing from activity theory, this study analyzes classroom data including drafts, author’s notes, and peer response materials as well as student interview data and writing center consultation transcripts. This dynamic approach allows for an exploration of the messiness of the process, creating a portrait of …

Untitled: Deconstruction And Reconstruction Of Identity In Le Chevalier De La Charrette And The Romance Of Tristran, Devin Louise Moulton

Department of Modern Languages and Literatures: Dissertations, Theses, and Student Research

Questions of identity are a central source of tension within the genre of the chivalric romances. Even among the large collective that is King Arthur’s court, innumerable romances recount the tales of individual knights in search of individual glory and of some way to distinguish their names among the masses of the court and the group of knights across chivalric traditions while simultaneously bound by the confines of that same group and its structures. For most, such a feat is impossible and many knights, though they may earn a name in the course of a single romance, never truly break …

Jerusalem’S Song: William Blake As Forerunner To Jung’S Feminist Psychology, Trudy D. Eblen

Department of English: Dissertations, Theses, and Student Research

William Blake's final epic poem, The Song of Jerusalem, consists of two textual narratives: the verbal (let me call it the conscious state) and the visual (the unconscious). I primarily focus on the visual, where the eponymous heroine psychically matures along the trajectory of a Jungian process of individuation (somewhat similar to the ancient universal initiation rite of maturation, as most famously described by Joseph Campbell). Preceding in Blake's corpus is a succession of his other female poetic characters, who represent various stages of successful and failed individuation—Thel, Lyca, Oothoon, and Ahania; these culminate in Jerusalem, Blake’s apotheotic female. …

Search For Resonant Double Higgs Production With Bbzz Decays In The Bbℓℓνν Final State In Pp Collisions At √S = 13 Tev, Rami Kamalieddin

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

Since the discovery of the Higgs boson in 2012 by the ATLAS and CMS experiments, most of the quantum mechanical properties that describe the long-awaited Higgs boson have been measured. Due to the outstanding work of the LHC, over a hundred of fb⁻¹ of proton collisions data have been delivered to both experiments. Finally, it became sensible for analyses teams to start working with a very low cross section processes involving the Higgs boson, e.g., a recent success in observing ttH and VHbb processes. One of the main remaining untouched topics is a double Higgs boson production. However, an …

The Relationship Between Socioeconomic Status And White Matter Microstructure In Pre-Reading Children: A Longitudinal Investigation, Ola Ozernov-Palchik, Elizabeth S. Norton, Yingying Wang, Sara D. Beach, Jennifer Zuk, Maryanne Wolf, John D.E. Gabrieli, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty Publications

Reading is a learned skill crucial for educational attainment. Children from families of lower socioeconomic status (SES) tend to have poorer reading performance and this gap widens across years of schooling. Reading relies on the orchestration of multiple neural systems integrated via specific white-matter pathways, but there is limited understanding about whether these pathways relate differentially to reading performance depending on SES background. Kindergarten white-matter FA and second-grade reading outcomes were investigated in an SES-diverse sample of 125 children. The three left-hemisphere white-matter tracts most associated with reading, and their right-hemisphere homologs, were examined: arcuate fasciculus (AF), superior longitudinal fasciculus …

Motor-Induced Suppression Of The N100 Event-Related Potential During Motor Imagery Control Of A Speech Synthesizer Brain–Computer Interface, Jonathan S. Brumberg, Kevin M. Pitt

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Speech motor control relies on neural processes for generating sensory expectations using an efference copy mechanism to maintain accurate productions. The N100 auditory event-related potential (ERP) has been identified as a possible neural marker of the efference copy with a reduced amplitude during active listening while speaking when compared to passive listening. This study investigates N100 suppression while controlling a motor imagery speech synthesizer brain–computer interface (BCI) with instantaneous auditory feedback to determine whether similar mechanisms are used for monitoring BCI-based speech output that may both support BCI learning through existing speech motor networks and be used as a …

Indigenous Data Governance: Strategies From United States Native Nations, Stephanie Russo Carroll, Desi Rodriguez-Lonebear, Andrew Martinez

Copyright, Fair Use, Scholarly Communication, etc.

Data have become the new global currency, and a powerful force in making decisions and wielding power. As the world engages with open data, big data reuse, and data linkage, what do data-driven futures look like for communities plagued by data inequities? Indigenous data stakeholders and non-Indigenous allies have explored this question over the last three years in a series of meetings through the Research Data Alliance (RDA). Drawing on RDA and other gatherings, and a systematic scan of literature and practice, we consider possible answers to this question in the context of Indigenous peoples vis-á-vis two emerging concepts: Indigenous …

Blancarte-Jasso, Gabriel Chepe-Cruz, Noemí G. Nah-Chan, Matilde M. Ortiz-García, Renee S. Arias

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

Tropical fruit trees are an important component of the human diet; however, little is known about their genetic diversity levels. Zapote mamey (Pouteria sapota) is a tree native to southeastern Mexico and Central America, and Mexico is the leading producer in the world. Studies of the genetic diversity of Zapote mamey have been based on cultivated materials using morphological and biochemical characterization or dominant molecular markers. To gain a deeper understanding about the conservation status of Zapote mamey in its center of origin and domestication, we collected 188 individuals from eight wild and five cultivated populations in southeastern Mexico and …
