Missing The (Turning) Point: The Erosion Of Democracy At An American University, Anthony Fucci, Theresa Catalano

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

On August 25, 2017, student members of Turning Point USA (TPUSA), a right-wing conservative organization who advocates for smaller government and free market enterprise, recruited on the University of Nebraska–Lincoln (UNL) campus. Members of the UNL community protested nearby. Part of the protest was recorded on video and released to social media leading to harsh public criticism that accused the university of restricting free speech and being an unsafe environment for conservative students. Drawing on cognitive linguistics (e.g. metonymy, framing) and multimodal critical discourse analysis (MCDA), this paper explores how the TPUSA incident at UNL was recontextualized in local and …

Children Of Mumbai’S Brothels: Investigating Developmental Prospects, Primary Relationships, And Service Provision, Rochelle L. Dalla, Sarah Erwin, Lee Kreimer

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

Objective: To understand the context of the lives of children reared in India’s red-light brothel districts. Background: Substantial empirical insight has emerged on the commercial sexual exploitation of children (CSEC). Yet the extant literature on brothel-based children (BBC), a uniquely vulnerable subset of at-risk children, is paradoxically deficient. Understanding the developmental needs of BBC is critical to mitigating risk.

Method: In-depth, semistructured interviews were conducted with 9 service providers and 30 women residing in 2 red-light brothel districts of Mumbai. Phenomenological inquiry informed the research methodology and data analysis.

Results: Mothers’ goals for children included survival, academic success, and future …

Foundations For Open Scholarship Strategy Development, Version 2.1 [Pre-Print], Jonathan Tennant, Jennifer E.

This document aims to agree on a broad, international strategy for the implementation of open scholarship that meets the needs of different national and regional communities but works globally.

Scholarly research can be idealised as an inspirational process for advancing our collective knowledge to the benefit of all humankind. However, current research practices often struggle with a range of tensions, in part due to the fact that this collective (or “commons”) ideal conflicts with the competitive system in which most scholars work, and in part because much of the infrastructure of the scholarly world is becoming largely digital. What is …

Photosynthesis, Yield And Raw Material Quality Of Sugarcane Injured By Multiple Pests, José A.S. Rossato Jr, Leonardo L. Madaleno, Márcia J.R. Mutton, Leon Higley, Odair A. Fernandes

School of Natural Resources: Faculty Publications

Understanding sugarcane (Saccharum spp.) response to multiple pest injury, sugarcane borer (Diatraea saccharalis) and spittlebug (Mahanarva fimbriolata), is essential to make better management decisions. Moreover, the consequences of both pests on the sugarcane raw material quality have not yet been studied. A field experiment was performed in São Paulo State, Brazil, where sugarcane plants were exposed to pests individually or in combination. Plots consisted of a 2-m long row of caged sugarcane plants. Photosynthesis was measured once every 3 months (seasonal measurement). Yield and sugar production were assessed. The measured photosynthesis rate was negatively affected by both borer and spittlebug …

Data Discovery Paradigms: User Requirements And Recommendations For Data Repositories, Mingfang Wu, Fotis Psomopoulos, Siri Jodha Khalsa, Anita De Waard

Copyright, Fair Use, Scholarly Communication, etc.

As data repositories make more data openly available it becomes challenging for researchers to find what they need either from a repository or through web search engines. This study attempts to investigate data users’ requirements and the role that data repositories can play in supporting data discoverability by meeting those requirements. We collected 79 data discovery use cases (or data search scenarios), from which we derived nine functional requirements for data repositories through qualitative analysis. We then applied usability heuristic evaluation and expert review methods to identify best practices that data repositories can implement to meet each functional requirement. We …

Cow-Calf Producers’ Willingness To Pay For Bulls Resistant To Horn Flies (Diptera: Muscidae), Lettie Mckay, Karen L. Delong, Susan Schexnayder, Andrew P. Griffith, David B. Taylor, Pia Olafson, R. T. Trout Fryxell

Department of Entomology: Faculty Publications

Horn flies (Haematobia irritans (L.)) have long posed animal health and welfare concerns. Economic losses to the cattle and dairy industries from their blood-feeding behavior include decreased weight gain, loss in milk productivity, and transmission of bacteria causing mastitis in cattle. Horn fly management strategies are labor intensive and can become ineffective due to the horn fly’s ability to develop insecticide resistance. Research indicates that for some cattle herds, genetically similar animals consistently have fewer flies suggesting those animals are horn fly resistant (HFR) and that the trait is heritable; however, it is currently unknown if cattle producers value this …

A Social Space Approach To Testing Complex Hypotheses: The Case Of Hispanic Marriage Patterns In The United States, Jeffrey A. Smith

Department of Sociology: Faculty Publications

Where do individuals identifying as Hispanic fit in the racial landscape of the United States? The answer offered by past work is complex: The empirical results do not lend themselves to simple interpretation as no single hypothesis fits the Hispanic case very well. Instead, Hispanic integration is described as mixtures of different archetypical hypotheses, like panethnic formation, white assimilation, and racialized assimilation. My goal is to develop a formal framework to help make sense of this complex picture. I extend past work by showing which combination of integration processes (panethnic formation, white assimilation, etc.) best characterizes Hispanic marriage patterns. I …

Pesticide Application Practices And Knowledge Among Small-Scale Local Rice Growers And Communities In Rwanda: A Cross-Sectional Study, Benjamin Ndayambaje, Hellen Amuguni, Jeanne Coffin-Schmitt, Nancy Sibo, Martin Ntawubizi, Elizabeth Vanwormer

School of Natural Resources: Faculty Publications

Background: Agriculture contributes a third of Rwanda’s GDP and is the main source of income for rural households, with 80% of the total population involved in crop and/or livestock production. The Government of Rwanda established the Muvumba rice project in 2011 amidst a policy shift towards rice as a national staple crop. However, the indiscriminate use of pesticides by local, low-income rice growers has raised concerns about potential human, animal and ecosystem health impacts as pesticide distribution and application are not strictly regulated. Although pesticide use can directly influence farmer health and ecosystems, little is known about small-scale farmers’ pesticide …

Twenty-Three Unsolved Problems In Hydrology (Uph) – A Community Perspective, Günter Blöschl, Christopher M. U. Neale, A Cast Of Thousands

Daugherty Water for Food Global Institute: Faculty Publications

This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through online media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focused …

Youth Perception Of Harm And Addictiveness Of Tobacco Products: Findings From The Population Assessment Of Tobacco And Health Study (Wave 1), David R. Strong, Karen Messer, Martha White, Yuyan Shi, Madison Noble, David B. Portnoy, Alexander Persoskie, Annette R. Kaufman, Kelvin Choi, Charles Carusi, Maansi Bansal-Travers, Andrew Hyland, John Pierce

United States Food and Drug Administration: Publications

Purpose: We provide a US national assessment of youth perceptions of the harm and addictiveness of six separate tobacco products, identifying a continuum of perceived harm associated with a range of products in relation to patterns of current use, former use, and susceptibility to use tobacco products.

Methods: We evaluated youth respondents (N=13,651) ages 12–17 from Wave 1 (2013–2014) of the Population Assessment of Tobacco and Health (PATH) Study. Analyses (2015–2016) focused on refining mea- sures of perceived harm for each product and delineating youth characteristics (demographic, tobacco use status) associated with beliefs about the harmfulness and addictiveness of tobacco …

Associations Of Risk Factors Of E-Cigarette And Cigarette Use And Susceptibility To Use Among Baseline Path Study Youth Participants (2013–2014), Michael D. Sawdey, Hannah R. Day, Blair Coleman, Lisa D. Gardner, Sarah E. Johnson, Jean Limpert, Hoda T. Hammad, Macieji L. Goniewicz, David B. Abrams, Cassandra A. Stanton, Jennifer L. Pearson, Annette R. Kaufman, Heather L. Kimmel, Cristine D. Delnevo, Wilson M. Compton, Maansi Bansal-Travers, Raymond S. Niaura, Andrew Hyland, Bridget K. Ambrose

United States Food and Drug Administration: Publications

Introduction: Improved understanding of the distribution of traditional risk factors of cigarette smoking among youth who have ever used or are susceptible to e-cigarettes and cigarettes will inform future longitudinal studies examining transitions in use.

Methods: Multiple logistic regression analysis was conducted using data from youth (ages 12–17 years) who had ever heard of e-cigarettes at baseline of the PATH Study (n = 12,460) to compare the distribution of risk factors for cigarette smoking among seven mutually exclusive groups based on ever cigarette/e-cigarette use and sus- ceptibility status.

Results: Compared to committed never users, youth susceptible to e-cigarettes, cigarettes, or …

Revisiting The Historic Distribution And Habitats Of The Whooping Crane, Jane E. Austin, Matthew A. Hayes, Jeb A. Barzen

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Understanding the historic range and habitats of an endangered species can assist in conservation and reintroduction efforts for that species. Individuals reintroduced into a species’ historic core range have a higher survival rate compared to individuals introduced near the periphery or outside the historic range (Falk and Olwell, 1992; Griffith et al., 1989). Individuals on the periphery of a species’ range tend to occupy less favorable habitats and have lower and more variable densities than those near the core of their range (Brown, 1984; Brown et al., 1995, 1996). Such conclusions, however, presume that historic habitats have not changed since …

Bittersweet Realities: Field Research, Human Rights, And Questioning Intentions, Laura Roost, Ryan M. Lowry, Patrice Mcmahon

University of Nebraska Public Policy Center: Publications

When Laura Roost and Ryan Lowry returned from their respective graduate fieldwork in Rwanda and the Balkans, their excited but bewildered debriefings were met by Professors Chantal Kalisa and Patrice McMahon, smiling and shaking their heads. Combined, Kalisa and McMahon had had extensive fieldwork experience in Africa, Europe, and Asia, and they saw in this debrief that the next generation of scholars was experiencing the same bittersweet realities of fieldwork that keeps researchers returning to the field despite ambiguities and frustrations. In an ever-connected world, doing fieldwork is necessary even when it seems redundant. Scholars now have large and accessible …

Disrupting Narrow Conceptions Of Justice: Exploring And Expanding "Bullying" And "Upstanding" In A University Honors Course, Jennifer Farley, Jennifer Gallagher, Katherine Richardson Bruna

University of Nebraska Public Policy Center: Publications

The term "upstanding" encompasses actions and behaviors grounded in one’s defense of their own beliefs and others. While such broad application of the term has merit, from a critical education perspective it lacks direction. To efficaciously address injustice, upstanding action must go beyond one’s beliefs. A directional application of upstanding behavior, or the notion of "upstanding for justice," frames upstanding as action to address chronic social victimization via systems of oppression. In this article, we describe the development of a new heuristic to support students’ understanding of upstanding and detail the university honors course in which we used the heuristic …

A Systematic Review Of Genetic Influence On Psychological Resilience, Kosuke Niitsu, Michael J. Rice, Julia F. Houfek, Scott F. Stoltenberg, Kevin A. Kupzyk, Cecilia R. Barron

Department of Psychology: Faculty Publications

When exposed to adversity, some individuals are at an increased risk of posttraumatic stress disorder, experiencing persistent biopsychosocial disturbances, whereas others adapt well, described as resilience. Resilience is a complex biopsychosocial phenomenon conceptualized as adaptation to adversity influenced by an individual’s genetic variants, epistasis, epigenetics, and gene-by-environment interactions. Studies on psychological resilience have focused on behavioral and psychosocial variables with far less examination of the genetic contributions. The purpose of this review is to identify specific genetic variants contributing to the biological capacity for psychological resilience. PubMed and PsycINFO were searched using the following key words: psychological resilience AND genotype …

Relations Between Young Adults’ Knowledge And Understanding, Experiences, And Information Behavior In Personal Finance Matters, Manuel Forster, Roland Happ, W. B. Walstad

Department of Economics: Faculty Publications

Background: In Germany, general secondary education offers few opportunities for young adults to acquire knowledge and understanding of personal finance. Hence, apart from parents’ influence as role models, important influences on young adults’ financial knowledge and understanding likely include their personal experience with financial products and their behavior of informally seeking information about specific financial products.

Methods: In this paper, we investigate the relationships between these latter variables based on a sample of 1108 young adults from Germany, aged 17–25, beginning their studies in higher education. Knowledge and understanding of personal finance was assessed using the German adaptation of the …

U.S. Adult Perceptions Of The Harmfulness Of Tobacco Products: Descriptive T Findings From The 2013–14 Baseline Wave 1 Of The Path Study, Geoffrey T. Fong, Tara Elton-Marshall, Pete Driezen, Annette R. Kaufman, K. Michael Cummings, Kelvin Choi, Jonathan Kwan, Amber Koblitz, Andrew Hyland, Maansi Bansal-Travers, Charles Carusi, Mary E. Thompson

United States Food and Drug Administration: Publications

Introduction: This study is the first nationally representative survey of U.S. adults (18+) to examine perceptions of the relative harms of eight non-cigarette tobacco products.

Methods: Data are from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study Adult Questionnaire, a nationally representative study of 32,320 adults in the United States conducted from September 2013 to December 2014.

Results: 40.7% of adults believed that electronic cigarettes were less harmful than cigarettes, and 17.8% of adults believed that hookah was less harmful than cigarettes. Those less knowledgeable about the health risks of smoking were more likely to believe …

A unique land management approach, agroforestry provides opportunities to integrate productivity and profitability with environmental stewardship to support healthy, sustainable agriculture systems, economies, and communities.

Molecular Insights Into Cage Occupancy Of Hydrogen Hydrate: A Computational Study, Rui Ma, Hong Zhong, Jinxiang Liu, Jie Zhong, Youguo Yan, Jun Zhang, Jiafang Xu

Department of Chemistry: Faculty Publications

Density functional theory calculations and molecular dynamics simulations were performed to investigate the hydrogen storage capacity in the sII hydrate. Calculation results show that the optimum hydrogen storage capacity is ~5.6 wt%, with the double occupancy in the small cage and quintuple occupancy in the large cage. Molecular dynamics simulations indicate that these multiple occupied hydrogen hydrates can occur at mild conditions, and their stability will be further enhanced by increasing the pressure or decreasing the temperature. Our work highlights that the hydrate is a promising material for storing hydrogen.

Dynamic Effects Of Habituation And Novelty Detection On Newborn Event Related Potentials, Cathryn S. Cortesa, Caitlin M Hudac, Dennis Molfese

Center for Brain, Biology, and Behavior: Faculty Publications

Newborns habituate to repeated auditory stimuli, and discriminate syllables, generating opportunities for early language learning. This study investigated trial-by-trial changes in newborn electrophysiological responses to auditory speech syllables as an index of habituation and novelty detection. Auditory event-related potentials (ERPs) were recorded from 16 term newborn infants, aged 1–3 days, in response to monosyllabic speech syllables presented during habituation and novelty detection tasks. Multilevel models demonstrated that newborns habituated to repeated auditory syllables, as ERP amplitude attenuated for a late-latency component over successive trials. Subsequently, during the novelty detection task, earlyand late-latency component amplitudes decreased over successive trials for novel …

Fad2 Gene Radiation And Positive Selection Contributed To Polyacetylene Metabolism Evolution In Campanulids1[Open], Tao Feng, Ya Yang, Lucas Busta, Edgar B. Cahoon, Hengchang Wang, Shiyou Lü

Center for Plant Science Innovation: Faculty Publications

Polyacetylenes (PAs) are bioactive, specialized plant defense compounds produced by some species in the eudicot clade campanulids. Early steps of PA biosynthesis are catalyzed by Fatty Acid Desaturase 2 (FAD2). Canonical FAD2s catalyze desaturation, but divergent forms can catalyze hydroxylation, conjugation, acetylenation, and epoxygenation. These alternate reactions give rise to valuable unusual fatty acids, including the precursors to PAs. The extreme functional diversity of FAD2 enzymes and the origin of PA biosynthesis are poorly understood from an evolutionary perspective. We focus here on the evolution of the FAD2 gene family. We uncovered a core eudicot-wide gene duplication event giving rise …

Re-Centering Teaching And Learning: Toward Communities Of Practice At The University Of Nebraska-Lincoln Libraries, Erica Defrain, Leslie Delserone, Elizabeth Lorang, Catherine F. Riehle, Toni Anaya

University of Nebraska-Lincoln Libraries: Faculty Publications

The scholarship of teaching and learning (SoTL) presents important opportunities that can transform learning, but many academic librarians at the University of Nebraska- Lincoln (UNL) struggle to find a scholarly center when their teaching roles are frequently that of external collaborator. Challenges such as access to student data, meaningful evaluations of instruction, limited opportunities for funding and professional development, and uncertainty over how to negotiate for these have contributed to librarians remaining on the periphery of SoTL work. Hoping to overcome some of these hurdles, UNL librarians are developing a community of practice (CoP) around teaching and learning.

Prehistoric Chaco Canyon, New Mexico: Importation Of Meat And Mmaize, Larry V. Benson, Deanna Grimstead, John R. Stein, David A. Rith, Terry L. Plowman

United States Geological Survey: Staff Publications

In a recent paper, Benson and Grimstead (2019) determined that only minimal amounts of maize could have been grown in Chaco Canyon due to its aridity, short growing season, and frequent summer flooding of the valley floor. In this paper it is shown that deer and rabbit densities within semiarid regions such as the Canyon are such that 2300 Canyon residents would eliminate essentially all small and large mammals within a year. This implies that food (meat and maize) must have been imported from one or more outlying areas to feed the Canyon's residential population. This would have entailed ~18,000 …

Honors Value Added: Where We Came From, And What We Need To Know Next, Hallie E. Savage

National Collegiate Honors Council Monographs: Chapters

The pressure is on, and growing greater when it comes to defining, disseminating, and defending the value of higher education generally and the reasons for funding it (Harnisch 2011). Complaints abound regarding the rising costs of higher education, and many legislators and the public are demanding accountability. Funding cuts are forcing many colleges and universities to prioritize and to evaluate what merits support and what does not. As a part of a large array of undergraduate programs, honors programs and honors colleges face increasingly greater pressure to justify their existence.

That said, honors programs and colleges are in a good …

Community College Honors Benefits: A Propensity Score Analysis, Jane B. Honeycutt

National Collegiate Honors Council Monographs: Chapters

According to Morgan and Badenhausen (2015), honors education began in the United States in 1921 when Frank Ayedelotte became president of Swarthmore College. At that time, Ayedelotte initiated an interdisciplinary curriculum that stressed critical thinking and active learning. Almost a century later, the National Collegiate Honors Council (2013) defines honors education in terms true to Ayedelotte’s original vision:

Honors education is characterized by in-class and extracurricular activities that are measurably broader, deeper, or more complex than comparable learning experiences . . . [and] honors experiences include a distinctive learnerdirected environment and philosophy. (para. 2)

Similar to four-year university honors programming, …

Nebraska Statewide Arboretum: Publications

The three main reasons for dividing perennials are to control the size of the plants, to help rejuvenate them, and to increase their number. Dividing and replanting keeps rapidly spreading perennials under control. Dividing will rejuvenate old plants, keeping them vigorous and blooming freely. Dividing perennials is an easy and inexpensive way to gain additional plants for your garden or to share.
