Management And Modeling Of Winter-Time Basil Cultivars Grown With A Cap Mat System, George E. Meyer, M. Elizabeth Conley, Ellen T. Paparozzi

Department of Agronomy and Horticulture: Faculty Publications

Basil (Ocimum basilicum) is a high value crop, currently grown in the field and greenhouses in Nebraska. Winter-time, greenhouse studies were conducted during 2015 and 2016, focusing on cultivars of basil grown on a Cap MAT II® system with various levels of fertilizer application. The goal was to select high value cultivars that could be grown in Nebraska greenhouses. The studies used water content, electrical conductivity, photosynthetically active radiation (PAR), and relative humidity, air and soil media temperature sensors. Greenhouse systems can be very complex, even though controlled by mechanical heating and cooling. Uncertain or ambiguous environmental and …

Real Potential, Jennifer Mckitrick

Department of Philosophy: Faculty Publications

There's a student in my philosophy class who has "real potential." I might express this thought in any of the following ways: "She is potentially a philosopher"; "She is a potential philosopher"; "She has the potential to be a philosopher." The first way uses a cognate of "potential" as an adverb to modify "is." The second ways uses "potential" as an adjective to modify "philosopher." However, the third way uses "potential" as a noun to refer to something that the student has. What kind of thing is this potential? One worry about even asking this question is that this nominalization …

Data were analyzed along the following dimensions: self-presentation, language(s), geographical location, temporality, public/private space, and type of text. At the same time, we describe the challenges involved in encoding names that follow different naming conventions, that were produced by speakers of two different languages, and that changed …

Working Memory In School-Age Children With And Without A Persistent Speech Sound Disorder, Kelly Farquharson, Tiffany Hogan, John E. Bernthal

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The aim of this study was to explore the role of working memory processes as a possible cognitive underpinning of persistent speech sound disorders (SSD).

Method: Forty school-aged children were enrolled; 20 children with persistent SSD (P-SSD) and 20 typically developing children. Children participated in three working memory tasks – one to target each of the components in Baddeley’s working memory model: phonological loop, visual spatial sketchpad and central executive.

Result: Children with P-SSD performed poorly only on the phonological loop tasks compared to their typically developing age-matched peers. However, mediation analyses revealed that the relation …

Research Design and Methods This study employs 20 years of data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly to estimate the proportion of life spent cognitively healthy and cognitively impaired prior to death among older Mexican adults residing in the southwestern United States. We combine age-specific mortality rates with age-specific prevalence of cognitive impairment, defined as a Mini-Mental Status Exam score of less than 21 …

Linguistic Landscape And Language Ideology: A Multimodal Analysis Of Government Websites In Morocco., Yassine Rfissa

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

Moroccan society has long been a multicultural society. It is characterized by linguistic complexity due to the variety of languages spoken in the region and the power relationship among languages used in politics, education, science, government...etc. The constitution names both Arabic and Tamazight languages as the co-official languages of the country, whereas French is still seen as a dominant language in the public sectors such as higher education, banking, commerce, science, industry, policy, and government affairs. In this paper, I examine the multifaceted use of language and the language choice in the virtual public sphere in Morocco and how this …

A Tidy Data Model For Natural Language Processing Using Cleannlp, Taylor Arnold

The R Journal

Recent advances in natural language processing have produced libraries that extract low level features from a collection of raw texts. These features, known as annotations, are usually stored internally in hierarchical, tree-based data structures. This paper proposes a data model to represent annotations as a collection of normalized relational data tables optimized for exploratory data analysis and predictive modeling. The R package cleanNLP, which calls one of two state of the art NLP libraries (CoreNLP or spaCy), is presented as an implementation of this data model. It takes raw text as an input and returns a list of normalized …

"Hear Us, See Us": Constructing Citizenship In The Margins, Tricia M. Hagen Gray

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

The meatpacking industry has drawn an increasing number of immigrants to the Midwestern community of Washington River from Mexico and Central America, making it a New Latino Diaspora (NLD) receiving community. Demographic change amidst the sociopolitical landscape of neoliberalism, declining civic engagement, and polarized partisan politics has forced interaction between longstanding residents and newcomers who are socially, culturally, and linguistically different. Historically marginalized groups have sought to claim rights—especially since Donald Trump’s election in 2016—resulting in a deeper fissure of the social landscape.

Washington River High School provided a context in which to explore questions about how students construct citizen …

Factors Associated To Teacher Longevity In A Title I Elementary School: A Qualitative Narrative Inquiry Study, Richard Devney

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

The potential of our nation is hinged upon the strength of our educational system across all 50 states. Public education is the backbone of our country and continues to be a spotlight of focus for many. In 1983, President Ronald Regan shared the “Nation at Risk” report, based on the findings from the National Commission on Excellence in Education. The report claimed a level of mediocrity permeated the public education system and children were lagging behind compared to children in other first world countries. This landmark report put a level of accountability on school officials to create higher performing students …

Foreword To D.W. Robertson, Jr., Uncollected Essays, Paul A. Olson

Department of English: Faculty Publications

During the late summer of 1992, I received a call from Darryl Gless, a professor of Renaissance literature at the University of North Carolina and my former student, asking me if it would be all right if he and other people looking after the literary remains of D. W. Robertson would send me a package of published and unpublished articles that Robertson had left behind upon his death in July of that year. Gless had been a friend of Dr. and Mrs. Robertson in Chapel Hill, visiting with them frequently while trying a bit to look after their well-being in …

Dispatches From Flyover Country: Four Appraisals Of Impacts Of Trump’S Immigration Policy On Families, Schools, And Communities, Edmund T. Hamann, Cara Morgenson

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

A university professor and high school ESL teacher, both based in Lincoln Nebraska, each write two short essays that detail implications of the Trump administration immigration policies for students, teachers, schools, and communities. The first two dispatches come from the transition period (after Trump won but while Obama still presided) while the latter two come from the 50-day mark of the Trump presidency. Juxtaposing voices contrasts overarching impact with the local; juxtaposing chronologies allows comparison of political promises and threats to early actions and reactions.

The Interaction Of Temporal And Spectral Acoustic Information With Word Predictability On Speech Intelligibility, Bahar Somayeh Shahsavarani

Department of Communication Studies: Dissertations, Theses, and Student Research

High-level, top-down information such as linguistic knowledge is a salient cortical resource that influences speech perception under most listening conditions. But, are all listeners able to exploit these resources for speech facilitation to the same extent? It was found that children with cochlear implants showed different patterns of benefit from contextual information in speech perception compared with their normal-haring peers. Previous studies have discussed the role of non-acoustic factors such as linguistic and cognitive capabilities to account for this discrepancy. Given the fact that the amount of acoustic information encoded and processed by auditory nerves of listeners with cochlear implants …

A Preliminary Study Of A Spanish Graphic Novella Targeting Hearing Loss Prevention, Mark Guiberson, Emily Wakefield

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: This preliminary study developed a digital graphic novella targeting hearing protection beliefs of Spanish-speaking agricultural workers. Researchers used pretest–posttest interview surveys to establish if the novella had an immediate influence on the participants’ beliefs about noise-induced hearing loss and usage of hearing protection devices.

Method: Researchers developed a digital graphic novella directed to increase knowledge about noise-induced hearing loss and increase the proper use of hearing protection devices. The novella was tailored to meet the specific linguistic and literacy needs of Spanish-speaking agricultural workers. Thirty-one Spanish-speaking farmworkers of Mexican nationality participated. This study included an interview survey with specific …

Secondary Students’ Writing Achievement Goals: Assessing The Mediating Effects Of Mastery And Performance Goals On Writing Self-Efficacy, Affect, And Writing Achievement, Meryem Yilmaz Soylu, Mary G. Zeleny, Ruomeng Zhao, Roger H. Bruning, Michael S. Dempsey, Douglas F. Kauffman

Department of Educational Psychology: Faculty Publications

The two studies reported here explored the factor structure of the newly constructed Writing Achievement Goal Scale (WAGS), and examined relationships among secondary students’ writing achievement goals, writing self-efficacy, affect for writing, and writing achievement. In the first study, 697 middle school students completed the WAGS. A confirmatory factor analysis revealed a good fit for this data with a three-factor model that corresponds with mastery, performance approach, and performance avoidance goals. The results of Study 1 were an indication for the researchers to move forward with Study 2, which included 563 high school students. The secondary students completed theWAGS, as …

Depressive Symptoms In Mexican-Origin Adolescents: Interrelations Between School And Family Contexts, Prerna G. Arora, Lorey Wheeler

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

This study, as guided by cultural-ecological frameworks, examined multiple contextual stressors, including subjective economic hardship, acculturation, discrimination, and negative perceptions of school safety, as simultaneously linked to adolescents’ depressive symptoms, as well as the role of gender, familism values, family cohesion, and school connectedness on these associations. Data come from the Children of Immigrants Longitudinal Study (Portes and Rumbaut 2012) that included second-generation 8th- and 9th-grade children of foreign-born parents from the Mexican-origin subsample (n = 755; 52% male; time 1 M age = 14.20 years). Adolescents were either born in (60%) or immigrated prior to age 5 to …

UReCA: The NCHC Journal of Undergraduate Research and Creative Activity

This literature review explored the available cultural support existing in the United States and abroad for internationally-educated nurses (IEN) and foreign-born student nurses (FBSN) in order to better understand how to improve patient outcomes by ensuring a successful cultural and linguistic transition into American nursing schools and clinical facilities. Fourteen articles regarding IEN and 12 articles regarding FBSN were used to compile recommendations to help create a more inclusive and supportive environment for IEN and FBSN in the United States. The results of this literature review indicate that there is an abundance of information regarding interventions for FBSN, but much …

Driven By Dreams: Immigrant Stories Of Education, A Gatekeeper Exam And A High School Diploma, Cindy H. Linzell

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

High school in the United States is an important time in any student’s life. For many students, the four years of high school are framed with classroom success and the earning of a high school diploma. For others, it is a very difficult time in their lives.

In the state of Nebraska, students are not permitted to continue their education in a public school setting past the age of 21. This age limit creates a deadline where the passing of classes and graduation tests becomes crucial if these students hope to earn their high school diploma. While the majority of …

Lessons To Be Learned: How A Comprehensive Neurobiological Framework Of Atypical Reading Development Can Inform Educational Practice, Ola Ozernov-Palchik, Xi Yu, Yingying Wang, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty Publications

Dyslexia is a heritable reading disorder with an estimated prevalence of 5–17%. A multiple deficit model has been proposed that illustrates dyslexia as an outcome of multiple risks and protective factors interacting at the genetic, neural, cognitive, and environmental levels. Here we review the evidence on each of these levels and discuss possible underlying mechanisms and their reciprocal interactions along a developmental timeline. Current and potential implications of neuroscientific findings for contemporary challenges in the field of dyslexia, as well as for reading development and education in general, are then discussed.

Effects Of Implicit Bias On Teachers’ Expectations Of Student Relationships, Colin Michael Mcginnis

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

Numerous studies have considered the implications of child characteristics such as race and gender on the relationships with and expectations of students held by teachers. Yet, few studies among this body of research have focused on using direct measures of implicit associations held by teachers, and considered how these implicit beliefs may impact their interactions with students. The present study examined differences in teachers’ expectations of relationships and likelihood to intervene in typical and disruptive behaviors as a result of differing race and gender of students. Results indicated that teachers report being less tolerant of Black student’s disruptive behavior than …

“A Doctor Is Less Valuable Than A Working Truck”: A Phenomenological Study Exploring International Immersion Experiences Of Primary Care Physicians Trained In The U.S., Julie M. Shasteen

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

This phenomenological study describes the experiences of primary care physicians trained in the United States who participated in an international clinical immersion rotation during medical school or residency. Five central themes emerge relating to their experience: (a) Participants chose the international rotation for developmental purposes. (b) The lifestyle in their destination country was different than in the U.S., and this had an impact on participants. (c) There were positive outcomes for participants and their future practice. (d) Harmful external forces (at the rotation site) shortened patients’ lifespans and had a negative impact on their quality of life. And, (e) participants …

Cultural Self-Identification Among Extension Educators' And Cultural Competence In Cooperative Extension, Ruddy Y. Benavides

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

As immigration and globalization are increasing, the number of people in our country who speak more than one language is also increasing (Center for Public Education, 2012). These trends are creating needs for culturally and linguistically diverse (CLD) students and families in schools, specifically, the need for culturally responsive pedagogy and culturally competent teachers. In addition to formal educational contexts, non-formal educational contexts such as Cooperative Extension need to adapt to cultural changes as well. The purpose of this study was to explore the personal beliefs and professional experiences of present Extension Educators (EEs), and the techniques they practice in …

Multi-Character Field Recognition For Arabic And Chinese Handwriting, Daniel Lopresti, George Nagy, Sharad C. Seth, Xiaoli Zhang

School of Computing: Conference and Workshop Papers

Two methods, Symbolic Indirect Correlation (SIC) and Style Constrained Classification (SCC), are proposed for recognizing handwritten Arabic and Chinese words and phrases. SIC reassembles variable-length segments of an unknown query that match similar segments of labeled reference words. Recognition is based on the correspondence between the order of the feature vectors and of the lexical transcript in both the query and the references. SIC implicitly incorporates language context in the form of letter n-grams. SCC is based on the notion that the style (distortion or noise) of a character is a good predictor of the distortions arising in other characters, …

Multilingual Literacies: Invisible Representation Of Literacy In A Rural Classroom, Lydiah Kananu Kiramba

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

In many countries, educational policies typically mandate school activities that promote a homogeneous and narrow range of academic literacies for all learners despite the diverse nature of human learning. This ethnographic case study examines how a 12-year-old Kenyan fourth-grade student performing below average on all standardized tests used multiple invisible literacies while documenting his knowledge and life experiences in a rural context. Invisible literacies are covert meaning- making literacy practices that are not privileged in the classroom. Examination of these practices shows a convergence between school and home literacies, suggesting a need for education stakeholders to identify literacies that are …

N400, P600, And Late Sustained Frontal Positivity Event-Related Brain Potentials Reflect Distinct Psycholinguistic Processes During The Comprehension Of Contextually Ambiguous Narrative Discourses: Implications For The Neural Organization Of The Language Processing System, Patrick S. Ledwidge

Department of Psychology: Dissertations, Theses, and Student Research

Two studies were performed to investigate the temporal structure and organization of the language processing system during the comprehension of coherent contextually ambiguous narrative discourses. In Study 1, participants read short discourses that were contextually ambiguous if read without a descriptive title (Untitled group) or unambiguous with the title (Titled group). Participants identified the title of the discourses after reading 1-3 sentences. Given the unfinished next sentence, they performed a cloze procedure on the sentence-final word. For the Titled Group, cloze probability was greater to the last word of sentence 3 (Critical Word 3) than sentences 2 (Critical Word 2) …
