A Qualitative Phenomenological Exploration Of Teachers’ Experience With Nutrition Education, Elisha M. Hall, Weiwen Chai, Julie A. Albrecht
A Qualitative Phenomenological Exploration Of Teachers’ Experience With Nutrition Education, Elisha M. Hall, Weiwen Chai, Julie A. Albrecht
Department of Nutrition and Health Sciences: Faculty Publications
Background:
Nutrition education delivered by classroom teachers has become a popular intervention designed to combat childhood obesity. However, few qualitative studies have explored nutrition education with teachers.
Purpose:
The purpose of this study was to explore how elementary teachers describe their experience with nutrition education.
Methods:
A qualitative phenomenological approach was used. Semistructured interviews, observations, and document analysis were conducted with 10 teachers who delivered nutrition education in their classrooms. Inductive coding was used to determine invariant constituents, reduce constituents to categories, and cluster categories into themes. Reliability and validity were accomplished through intercoder agreement, audio recording, triangulation, bracketing, and …

Mental Health Disparities Within The Lgbt Population: A Comparison Between Transgender And Nontransgender Individuals, Dejun Su, Jay A. Irwin, Christopher Fisher, Athena Ramos, Megan Kelley, Diana Ariss Rogel Mendoza, Jason D. Coleman
Department of Nutrition and Health Sciences: Faculty Publications
Purpose: This study assessed within a Midwestern LGBT population whether, and the extent to which, transgender identity was associated with elevated odds of reported discrimination, depression symptoms, and suicide attempts.
Methods: Based on survey data collected online from respondents who self-identified as lesbian, gay, bisexual, and/or transgender persons over the age of 19 in Nebraska in 2010, this study performed bivariate t- or chisquare tests and multivariate logistic regression analysis to examine differences in reported discrimination, depression symptoms, suicide attempts, and self-acceptance of LGBT identity between 91 transgender and 676 nontransgender respondents.
Results: After controlling for the effects …
Association Of Individual And Community Factors With C-Reactive Protein And 25-Hydroxyvitamin D: Evidence From The National Health And Nutrition Examination Survey (Nhanes), Weiwen Chai, Jessie X. Fan, Ming Wen
Association Of Individual And Community Factors With C-Reactive Protein And 25-Hydroxyvitamin D: Evidence From The National Health And Nutrition Examination Survey (Nhanes), Weiwen Chai, Jessie X. Fan, Ming Wen
Department of Nutrition and Health Sciences: Faculty Publications
Many individual and community/neighborhood factors may contribute to inflammation and vitamin D deficiency leading to the development of chronic diseases. This study examined the associations of serum Creactive protein (CRP) and 25-hydroxyvitamin D [25(OH)D] levels with individual and community/neighborhood (tract-level or county-level) factors using a nationally representative sample from 2001–2006 National Health and Nutrition Examination Survey (NHANES). Data from the 2001–2006 waves of the continuous NHANES was merged with the 2000 census and other neighborhood data sources constructed using geographic information system. Associations between multilevel factors and biomarker levels were assessed using multilevel random-intercept regression models. 6643 participants aged 19–65 …
Food Insecurity And Housing Instability In Vulnerable Families, Christian King
Food Insecurity And Housing Instability In Vulnerable Families, Christian King
Department of Nutrition and Health Sciences: Faculty Publications
Reducing the prevalence of household food insecurity has been a long-standing objective of the federal government. Previous research has found many negative consequences of food insecurity for families and households but has not examined its relationship with housing instability. Using longitudinal data from the Fragile Families and Child Wellbeing Study, difference-in-difference models show that food insecurity is associated with housing instability. The association remains statistically significant after accounting for potential selection and unobserved heterogeneity using propensity score matching and excluding households that experienced prior housing instability from the sample. Examining potential mediating factors, I find that material hardship explains about …
“I’M Here To Do Business. I’M Not Here To Play Games.” Work, Consumption, And Masculinity In Storage Wars, Mark A. Rademacher, Casey Ryan Kelly
“I’M Here To Do Business. I’M Not Here To Play Games.” Work, Consumption, And Masculinity In Storage Wars, Mark A. Rademacher, Casey Ryan Kelly
Department of Communication Studies: Faculty Publications
This essay examines the first season of Storage Wars and suggests the program helps mediate the putative crisis in American masculinity by suggesting that traditional male skills are still essential where knowledge supplants manual labor. We read representations of “men at work” in traditionally “feminine” consumer markets as a form of masculine recuperation situated within the culture of White male injury. Specifically, Storage Wars appropriates omnivorous consumption, thrift, and collaboration to fit within the masculine repertoire of self-reliance, individualism, and competition. Thus, the program adapts hegemonic masculinity by showcasing male auction bidders adeptly performing feminine consumer practices. Whether the feminine …
Chastity For Democracy: Surplus Repression And The Rhetoric Of Sex Education, Casey Ryan Kelly
Chastity For Democracy: Surplus Repression And The Rhetoric Of Sex Education, Casey Ryan Kelly
Department of Communication Studies: Faculty Publications
Moving from opposition to participation, the Adolescent Family Life Act (1981) and the development of abstinence education marks the conservative movement’s pivot to a rhetorical strategy of tolerance that enabled it to coopt the public culture of sex discourse. Working from Herbert Marcuse’s theory of “surplus repression,” I argue that the New Right seized the liberationist argument for open public discourse about sexuality to sublimate libidinal desires into a national project of familial (re)productivity. The AFLA is significant in the rhetorical history of sex education because it demarcates the transition to a productive form of biopolitics that sought to manage …
“Uh Oh. Cue The [New] Mommy Wars”: The Ideology Of Combative Mothering In Popular U.S. Newspaper Articles About Attachment Parenting, Julia Moore, Jenna Abetz
“Uh Oh. Cue The [New] Mommy Wars”: The Ideology Of Combative Mothering In Popular U.S. Newspaper Articles About Attachment Parenting, Julia Moore, Jenna Abetz
Department of Communication Studies: Faculty Publications
Through critique of concordance, we argue that popular U.S. newspaper articles about attachment parenting perpetuate the ideology of combative mothering, where mothers are in continuous competition with one another over parenting choices. Specifically, article writers construct a new, singular metaphorical mommy war between pro-attachment parenting and anti-attachment parenting proponents by prepackaging attachment parenting and its debate, advocating for attachment parenting through instinct and science, and rejecting attachment parenting because of harm to children, relationships, and mothers. A minority of articles, however, avoided reifying this pro-/anti-attachment parenting mommy war by exploring the complexities of parenting beyond prepackaged philosophies. We explore the …
The Impact Of Religious Commitment On Women’S Sexual Self-Esteem, Dena Abbott, Jeff E. Harris, Debra Mollen
The Impact Of Religious Commitment On Women’S Sexual Self-Esteem, Dena Abbott, Jeff E. Harris, Debra Mollen
Department of Educational Psychology: Faculty Publications
Religious commitment is associated with decreased sexual activity, poor sexual satisfaction, and sexual guilt, particularly among women. The purpose of this paper was to investigate how religious commitment is related to sexual self-esteem among women. Participants included 196 female undergraduate students, 87 % of whom identified as Christian. Participants completed the Sexual Self-Esteem Inventory for Women (SSEI-W), Religious Commitment Inventory-10, Revised Religious Fundamentalism Scale, Brief Sexual Attitudes Scale, and a measure of their perception of God’s view of sex. Results suggested that women with high religious commitment held more conservative sexual attitudes. Significant relationships between religious commitment and two subscales …

Estimates Of Small Indian Mongoose Densities: Implications For Rabies Management, Shylo R. Johnson, Are R. Berentsen, Christine Ellis, Amy Davis, Kurt C. Vercauteren
Estimates Of Small Indian Mongoose Densities: Implications For Rabies Management, Shylo R. Johnson, Are R. Berentsen, Christine Ellis, Amy Davis, Kurt C. Vercauteren
United States Department of Agriculture Wildlife Services: Staff Publications
The small Indian mongoose (Herpestes auropunctatus) is an invasive species and rabies reservoir in Puerto Rico. In the continental United States, terrestrial wildlife rabies is primarily managed by the National Rabies Management Program (NRMP) of the United States Department of Agriculture through oral rabies vaccination (ORV); the distribution of the vaccine baits is influenced by the population density of the target species. TheNRMPuses a density index for estimating raccoon (Procyon lotor) population density to guide bait distribution. In Puerto Rico, a wildlife rabies vaccination program does not exist and vaccination of domestic animals is limited and not compulsory. …
Quantifying The Adaptive Cycle, David G. Angeler, Craig R. Allen, Ahjond S. Garmestani, Lance H. Gunderson, Olle Hjerne, Monika Winder
Quantifying The Adaptive Cycle, David G. Angeler, Craig R. Allen, Ahjond S. Garmestani, Lance H. Gunderson, Olle Hjerne, Monika Winder
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
The adaptive cycle was proposed as a conceptual model to portray patterns of change in complex systems. Despite the model having potential for elucidating change across systems, it has been used mainly as a metaphor, describing system dynamics qualitatively. We use a quantitative approach for testing premises (reorganisation, conservatism, adaptation) in the adaptive cycle, using Baltic Sea phytoplankton communities as an example of such complex system dynamics. Phytoplankton organizes in recurring spring and summer blooms, a well-established paradigm in planktology and succession theory, with characteristic temporal trajectories during blooms that may be consistent with adaptive cycle phases. We used long-term …
Adherence And Dosage Contributions To Parenting Program Quality, Thomas J. Gross, W. Alex Mason, Gilbert R. Parra, Robert Oats, Jay Ringle, Kevin P. Haggerty
Adherence And Dosage Contributions To Parenting Program Quality, Thomas J. Gross, W. Alex Mason, Gilbert R. Parra, Robert Oats, Jay Ringle, Kevin P. Haggerty
Department of Child, Youth, and Family Studies: Faculty Publications
Objective—The 3 most frequently examined elements of treatment fidelity are adherence, dosage, and quality. The relationships between these fidelity elements are complex, and additional research is needed to provide clarity. Improving clarity may be especially relevant to parenting programs, which tend to include direct explicit instruction (DEI) elements (i.e., instruction, modeling, and practice). The adherence to and dosage of these DEI elements are frequently assumed to improve program quality; however, little information is available to determine if such adherence and dosage affect program quality. This study examines whether adherence to and dosage of DEI elements predict quality ratings for …
Making Marital Rape Visible: A History Of American Legal And Social Movements Criminalizing Rape In Marriage, Joann M. Ross
Making Marital Rape Visible: A History Of American Legal And Social Movements Criminalizing Rape In Marriage, Joann M. Ross
Department of History: Dissertations, Theses, and Student Research
This study examines the history of marital rape and related topics in the United States within the broader context of women’s legal and political rights. The project demonstrates the interplay between women’s activists, legislators, the criminal justice system, and an involved public necessary to change both societal and legal views on spousal rape, and eventually its criminalization in all fifty states.
Concentrating on approaches to criminalizing marital rape in three of the fifty states, this dissertation provides a reasonable representation of the existence of the marital rape exemption in America, arguments used to maintain the exemption, and various methods used …
Network Support Variation For Black Women In The United States: A Mobility Study Of Immigrant And Non-Immigrant Black Women, Lesa Annette Johnson
Network Support Variation For Black Women In The United States: A Mobility Study Of Immigrant And Non-Immigrant Black Women, Lesa Annette Johnson
Department of Sociology: Dissertations, Theses, and Student Research
Connections between socioeconomic status, social capital, and social support have been quite prominent in sociological research. However, such research still largely ignores the experiences of recently arrived African immigrants, particularly those who arrive as refugees. Black immigrants who arrived in the United States since 1965 have included an increasing number of refugees from war-torn, sub-Saharan African countries, such as the recently independent South Sudan. The numbers of women in these refugee roles has steadily increased since 1990. Black refugee women, many with children, bring diverse forms of social capital that influence their social networks and economic mobility, distinguishing them from …
Assessing The Sociocultural Impact Of Special Events In The Context Of Germanfest In Nebraska, Usa, Yanli Wang
Assessing The Sociocultural Impact Of Special Events In The Context Of Germanfest In Nebraska, Usa, Yanli Wang
Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research
The present study examined the sociocultural impact of special events based on the cultural festival of GermanFest in Syracuse, Nebraska. A total of 143 (71.5%) local residents responded to the self-administered survey. The dimensions of the sociocultural impact, the important reasons for celebrating the festival, the relationship among festival stakeholders, the levels of community involvement, and the improvement of the quality of life in the community as impacts of the festival and demographic information were investigated separately.
The Festival Social Impact Attitude Scale (FSIAS) was utilized to identify the dimensions of the sociocultural impact of GermanFest. Three dimensions were identified …
Substance Use Disorders, Comorbidity, And Arrest Among Indigenous Adolescents*, Kelley J. Sittner Hartshorn, Les B. Whitbeck, Patricia Prentice
Substance Use Disorders, Comorbidity, And Arrest Among Indigenous Adolescents*, Kelley J. Sittner Hartshorn, Les B. Whitbeck, Patricia Prentice
Department of Sociology: Faculty Publications
Indigenous adolescents are overrepresented at multiple stages of the justice system, but we know very little about the role that mental health, particularly substance use disorder, plays in Indigenous pathways to arrest. This study examined the association between substance use disorder, its comorbidity with other disorders, and arrest using a longitudinal sample of Indigenous youth from the Northern Midwest and Canada. Of the 16% of youth who reported at least one arrest at Wave 5, half met criteria for substance abuse/dependence, and slightly more for conduct disorder. Substance abuse/dependence and conduct disorder were each associated with an increased risk of …

Conclusion
Educators need to take a more active role in identifying and addressing sleep related issues in students in order to maximize their learning potential and to minimize the numerous negative outcomes of sub-optimal sleep and sleep disorders. Specifically, school personnel can educate parents on the importance of sleep and advocate for later school start times for middle and high school students. In addition, when symptoms persist, educators can make recommendations to parents as a part of the SAT and MDT. See Figure 4 for recommendations for schools.

Trust Within Higher Education Consortia: A Phenomenological Study Of The Experiences Of Directors And Leaders, James A. Yankech
Trust Within Higher Education Consortia: A Phenomenological Study Of The Experiences Of Directors And Leaders, James A. Yankech
Department of Educational Administration: Dissertations, Theses, and Student Research
Trust is a foundational element for success within a higher education consortium. Defined as a group of colleges and universities united through collective effort, a consortium allows member institutions to achieve more cooperatively than alone. However these same institutions still compete in many ways – for students, government appropriations, and research dollars as examples. Therefore a balance must be struck between institutional and consortium interests. As a result trust between and among member institutions of a consortium becomes an important phenomenon to be understood. This study examined the phenomenon of trust from the perspective of consortia directors and leaders. Two …
Motherhood As Contested Ideological Terrain: Essentialist And Queer Discourses Of Motherhood At Play In Female–Female Co-Mothers’ Talk, Elizabeth A. Suter, Leah M. Seurer, Stephanie Webb, Brian Grewe Jr., Jody Koenig Kellas
Motherhood As Contested Ideological Terrain: Essentialist And Queer Discourses Of Motherhood At Play In Female–Female Co-Mothers’ Talk, Elizabeth A. Suter, Leah M. Seurer, Stephanie Webb, Brian Grewe Jr., Jody Koenig Kellas
Department of Communication Studies: Faculty Publications
Framed by relational dialectics theory (Baxter), this investigation considered the meaning(s) of motherhood in female–female co-motherhood. Analysis identified two competing discourses: (1) discourse of essential motherhood (DEM) and (2) discourse of queer motherhood (DQM). Speakers’ invocation of the DEM reinscribes the mainstream US cultural discourse that children can have only one authentic (i.e., biological) mother, whereas invocation of the DQM denaturalizes the DEM’s presumptions of authentic motherhood as biological, interrupts monomaternalism, destabilizes the patriarch, and troubles the equation of biological with moral motherhood. Whereas interpenetrations of the DEM and DQM were typically sites of adversarial discursive struggle, in a few …
Competing For Attention: A Comparative Study Of Social Movements And News Media In Abortion Debates, Katherine Eugene Lebreton Hunt
Competing For Attention: A Comparative Study Of Social Movements And News Media In Abortion Debates, Katherine Eugene Lebreton Hunt
Department of Political Science: Dissertations, Theses, and Student Research
Why do some social movements in abortion debates get more attention from the news media than others? Do movements that support the status quo receive more attention than those opposing the status quo? Through quantitative content analysis of eight major newspapers in South Korea, Ireland, and Canada and fieldwork in South Korea and Ireland, I theorize that antistatus quo groups – whether they are for or against abortion rights – may reopen debate conditions in their countries by strategically using international human rights norms and frames and gaining standing in the news media in environments that tend to be hostile …
A Correlational Case Study On Distance From Home And Attrition Of First-Time, Full-Time Students, James L. Baldwin
A Correlational Case Study On Distance From Home And Attrition Of First-Time, Full-Time Students, James L. Baldwin
Department of Educational Administration: Dissertations, Theses, and Student Research
As institutions face increasing demands to maintain or increase enrollments, colleges and universities have begun to recruit students from greater distances. The purpose of this ex-post facto case study was to determine the existence of a relationship between the institutional distance from home and the attrition of traditional-aged, first-time, full-time students prior to the second year at the University of Pittsburgh at Bradford, one of the four-year campuses of the University. Following the correlational analysis, further analysis was conducted to determine if a non-linear relationship existed between the institutional distance from home and attrition of first-year students prior to their …
Adolescent Survival Expectations: Variations By Race, Ethnicity, And Nativity, Tara D. Warner, Raymond R. Swisher
Adolescent Survival Expectations: Variations By Race, Ethnicity, And Nativity, Tara D. Warner, Raymond R. Swisher
Department of Sociology: Faculty Publications
Adolescent survival expectations are linked to a range of problem behaviors, poor health, and later socioeconomic disadvantage, yet scholars have not examined how survival expectations are differentially patterned by race, ethnicity, and/or nativity. This is a critical omission given that many risk factors for low survival expectations are themselves stratified by race and ethnicity. Using the National Longitudinal Study of Adolescent to Adult Health, we modeled racial, ethnic, and immigrant group differences in trajectories of adolescent survival expectations and assess whether these differences are accounted for by family, neighborhood, and/or other risk factors (e.g., health care access, substance use, exposure …
Grounded Theory’S Contested Family Of Methods: Historical And Contemporary Applications, Wayne A. Babchuk
Grounded Theory’S Contested Family Of Methods: Historical And Contemporary Applications, Wayne A. Babchuk
Discipline-Based Education Research Group Speaker Series
This presentation provides a concise overview of the history, development, and contemporary applications of grounded theory, a methodology originally developed in sociology but now arguably the most widely used qualitative approach across disciplines. From its early formulation by Glaser and Strauss to their contentious and widely publicized split, new epistemologically and theoretically repositioned approaches have emerged that together make up grounded theory’s “family of methods.” Grounded theory’s shared characteristics, divergent approaches, and hybrid designs including “grounded theory ethnography” and mixed methods or “pragmatist” grounded theory are discussed.
Attractor-Based Obstructions To Growth In Homogeneous Cyclic Boolean Automata, Bilal Khan, Yuri Cantor, Kirk Dombrowski
Attractor-Based Obstructions To Growth In Homogeneous Cyclic Boolean Automata, Bilal Khan, Yuri Cantor, Kirk Dombrowski
Department of Sociology: Faculty Publications
We consider a synchronous Boolean organism consisting of N cells arranged in a circle, where each cell initially takes on an independently chosen Boolean value. During the lifetime of the organism, each cell updates its own value by responding to the presence (or absence) of diversity amongst its two neighbours’ values. We show that if all cells eventually take a value of 0 (irrespective of their initial values) then the organism necessarily has a cell count that is a power of 2. In addition, the converse is also proved: if the number of cells in the organism is a proper …

The Family Mealtime Study: Parent Socialization And Context During And Surrounding Family Mealtimes, Car Mun Kok
The Family Mealtime Study: Parent Socialization And Context During And Surrounding Family Mealtimes, Car Mun Kok
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Past research showed that family mealtimes positively impact youth's dietary behaviors. However, the processes through which these benefits occur are unclear. Understanding the aspects of family mealtimes such as parent socialization and mealtime context can increase the understanding of how family mealtimes may benefit youths’ dietary behaviors. This mixed methods study identified occurrences around family mealtimes that might impact youths’ dietary behaviors. One hundred parent-child dyads completed surveys. A subsample of 40 families participated in family mealtime observations and 20 parents were interviewed. Quantitative findings showed that parents engaged in various food- and mealtime-related socialization behaviors like parent modeling, parent …

Improving The Network Scale-Up Estimator: Incorporating Means Of Sums, Recursive Back Estimation, And Sampling Weights, Patrick Habecker, Kirk Dombrowski, Bilal Khan
Department of Sociology: Faculty Publications
Researchers interested in studying populations that are difficult to reach through traditional survey methods can now draw on a range of methods to access these populations. Yet many of these methods are more expensive and difficult to implement than studies using conventional sampling frames and trusted sampling methods. The network scale-up method (NSUM) provides a middle ground for researchers who wish to estimate the size of a hidden population, but lack the resources to conduct a more specialized hidden population study. Through this method it is possible to generate population estimates for a wide variety of groups that are perhaps …

Land-Use Change Impact On Soil Sustainability In A Climate And Vegetation Transition Zone, K. D. Reitsma, B. H. Dunn, U. Mishra, S. A. Clay, T. Desutter, D. E. Clay
United States Department of Energy: Publications
A growing world population and climate change are expected to influence future agricultural productivity and land use. Th is study determined the impact of land-use change on soil sustainability and discussed the factors contributing to these changes. South Dakota was selected as a model system because corn (Zea mays L.) grain prices tripled between 2006 and 2012 and it is located in a climate and grassland/cropland transition zone. High resolution imagery was used to visually determine land uses (cropland, grassland, nonagricultural, habitat, and water) at 14,400 points in 2006 and 2012. At each point, land-use change and the USDA land …

Switchgrass Germplasm Resources, Michael D. Casler, Kenneth P. Vogel, Melanie Harrison
Department of Agronomy and Horticulture: Faculty Publications
Switchgrass (Panicum virgatum L.) is an important native grass and dominant member of the tallgrass prairie ecosystem. It is used for conservation, restoration, livestock feed production, and bioenergy feedstock production. The purpose of this review is to describe the biological and geographical basis for switchgrass germplasm diversity and to provide a resource for scientists and outreach personnel to find switchgrass germplasm to meet their needs. Upland and lowland ecotypes represent the most important polymorphism in switchgrass, with distinct but overlapping geographic distributions. Variation in ploidy exists within both ecotypes, with 2n = 4x = 36 the dominant ploidy …
