Beyond The Plot: Learning Through Fiction, Anne Kluthe

Honors Program: Expanded Learning Clubs

Encourage learning about complex, confusing, or even just random topics that were covered in fictional stories. Later on, shift the narrative from "discover new topics from what we are reading" to "what is the author trying to say here? What was their intent? What clues is the author giving us, and what do you think will happen next in the story?". This brings elementary schoolers a first interaction with deeper English themes, such as author's intent, at a low-stakes interaction to build confidence in the works and in themselves.

Cats And Cows Yoga Club, Kate Gaulke

Honors Program: Expanded Learning Clubs

Numerous studies have shown that yoga can be very beneficial for kids. Cats and Cows Yoga Club will help children learn the postures of yoga, but also teach them the importance of mindfulness. I include lessons that preach kindness and gratefulness which compliments the practice of yoga very well. Ultimately, children will become aware of how it feels when they deep breathe and the difference it makes in your mood when you focus on mindfulness in your body, mind, and spirit.

Racial–Ethnic Disparities In Prediabetes And Diabetes Among Us Adults, Carly Selleck, Jennifer R. Mcatee, Weiwen Chai

UCARE: Research Products

Type-2 diabetes is a chronic metabolic disease affecting more than3 4 million Americans or 10.5% of the population [1]. While almost 90% of people are not aware of their prediabetes status, around 88 million adults are considered to be prediabetic [2]. Without any prevention methods, 70% of prediabetes cases will eventually develop into diabetes[3]. While the development of type-2 diabetes is multifactorial, lifestyle factors such as diet and physical activity as well as socioeconomic (SES) factors such as poverty and education can be main contributors [4]. This study aimed to assess racial-ethnic differences in SES, lifestyle factors and prevalence of …

Rural-Urban Differences In Roles And Support For Community Health Workers In The Midwest, Kate E. Trout, Virginia Chaidez, Angela L. Palmer-Wackerly

Department of Nutrition and Health Sciences: Faculty Publications

The Patient Protection and Affordable Care Act supports the integration of community health workers (CHWs) into the health care workforce, but little is known about integration and current roles of CHWs among employers in community settings. This analysis of 97 employers described the roles of CHWs in Nebraska and found significant differences between CHWs practicing in rural and urban areas in organization types employing CHWs, funding sources, and minority populations served. The findings suggest that the utility of CHWs is widely recognized among employers, but deliberate support will be needed to better define the roles of CHWs to meet the …

A Global Perspective On Sustainable Intensification Research, Kenneth Cassman, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Despite general agreement that meeting food demand without further loss of natural ecosystems requires sustainable intensification, there is little dialogue about the research agenda needed to achieve it. To that end, we evaluate current trajectories towards sustainable intensification, review published research on the topic, identify missing links, and propose a prioritization framework to fill gaps. Although progress towards sustainable intensification is behind schedule, we are optimistic that current trends can get back on course assuming a well-prioritized and adequately funded research portfolio and appropriate policies and institutions to support it.

Stunting And Infectious Disease In Ethiopian And Zambian Children, Alyssa Arndt

NUTR/GLST 498b: Global Research Experiences in Nutrition and Health

PURPOSE: To evaluate whether children who are malnourished/stunted are more likely to have experienced infectious disease.

METHODS: 6th and 7th students (n=546) were interviewed about health history and assessed using anthropometry.

RESULTS: Children who are short for their age also have higher rates of stunting. Malaria is the most experienced infectious disease.

CONCLUSIONS: Given that malaria was the most common infectious disease experience listed among middle school children, and that those who have experienced disease are more likely to be stunted, increased malaria prevention methods may improve the long-term health of Ethiopian and Zambian schoolchildren.

Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil

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

Prediction of energy expenditure allows for calculation of appropriate energy requirements, which is especially important for athletes. Resting metabolic rate (RMR) is the greatest contributor to total daily energy expenditure (TDEE) and is typically measured via indirect calorimetry. Indirect calorimetry is not always available, which results in the need for predictive equations. Most predictive equations have been developed with participants resembling the general population and have not been found to be appropriate for athletes, as they may incorrectly predict RMR due to the unique differences of body composition between athletes and the general population. The purpose of the present study …

Comparative Physiology Of Honey Bees (Apis Mellifera L.) Exposed To Chlorantraniliprole, Jennifer Williams

Department of Entomology: Dissertations, Theses, and Student Research

One outstanding threat to the honey bee, Apis mellifera L., is the unintended exposure of these pollinators to agricultural pesticides. Anthranilic diamides, such as chlorantraniliprole, work in target pests through activation of the ryanodine receptor causing rapid feeding cessation, lethargy, paralysis, and eventual death. Chlorantraniliprole exhibits low acute toxicity to honey bees but relatively little information exists regarding effects of chlorantraniliprole exposure beyond mortality. The acute toxicity and metabolic detoxification enzyme activities following oral exposure were determined in the honey bee and the model crop pest, the fall armyworm (Spodoptera frugiperda, J.E. Smith). Additionally, chlorantraniliprole effects on honey bee …

Maize Growth, Yield, Water Productivity And Evapotranspiration Response To Different Irrigation Methods And Amounts And Different Timing And Methods Of Nitrogen Applications, Ali T. Mohammed

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Declining the quantity and quality of freshwater resources in many parts of the world, including Midwestern USA, especially in the light of rapidly growing world’s population and changing climate, imposes significant and, in some cases imminent, challenges for producers, policy- and decision-makers to produce more yield with less water and other inputs, particularly in water scarcity regions.

There is not comprehensive previous research has quantified and evaluated coupled impacts of irrigation rates and nitrogen timing management strategies and their interactions on maize (Zea mays L.) productivity and its various attributed efficiency index metrics under different irrigation methods under the …

An Analysis Of Social Dominance In The Feeding Of Ex Situ Humboldt Penguins (Spheniscus Humboldti), Robert Gabel

Honors Program: Senior Projects (Public)

In the field of ecology, complex social structures, including dominance hierarchies, have been demonstrated in a variety of fauna, including bird species. While wild Humboldt Penguins (Spheniscus humboldti) do not exhibit a feeding hierarchy, captive penguins are under very different conditions. Humboldt penguins feed on schooling fish in the wild, but in captivity are hand fed from a zookeeper. I investigated whether there is a nonrandom pattern of dominance in the feeding order of the penguins at the Lincoln Children’s Zoo, in Lincoln, NE, USA. Using a camera and tripod, with assistance from four of the zookeepers, I …

Mothers’ Experience With Infant Complementary Feeding Practices: A Phenomenological Study., Tyler Martin

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Background. Complementary feeding practices include what, when, and how to feed (Birch and Doub, 2014). The gradual transition from feeding exclusively human milk, formula milk, or a combination of both to complementary foods over the first 24 months of life is necessary to ensure proper growth and development (Dewey, 2001; Pearce & Langley-Evans, 2013). While research does exist on complementary feeding, such as infant diet composition, limited research exists on exploring complementary feeding practices from first-time mothers’ experiences.

Methods. This study utilized transcendental phenomenological qualitative research methodology. A pilot tested semi-structured interview guide was used to examine demographics as …

How Does The Social World Shape The Experience Of A Rare Disease? Social Position And The Development, Progression, And Medical Care For People With Amyotrophic Lateral Sclerosis, Jennifer A. Andersen

Department of Sociology: Dissertations, Theses, and Student Research

This dissertation focuses on the implications of social position and life course on the experience of Amyotrophic Lateral Sclerosis (ALS). Using a sociology in medicine frame, I test three theoretical perspectives (fundamental cause theory, social determinants of health, and life course theory) to determine the influence of social conditions on the development and progression of, and medical care for, people with ALS (pALS). Further, I use ALS as an exemplar of the need for a sociology of disease.

Using the Amyotrophic Lateral Sclerosis National Registry, I first assess the association of social position with the reported onset location at the …

Effect Of Temperature On Plant Resistance To Arthropod Pests, James R. Nechols, Ashley R. Hough, David C. Margolies, John R. Ruberson, Brian P. Mccornack, Brett K. Sandercock, Leigh Murray

Department of Entomology: Faculty Publications

Temperature has a strong influence on the development, survival, and fecundity of herbivorous arthropods, and it plays a key role in regulating the growth and development of their host plants. In addition, temperature affects the production of plant secondary chemicals as well as structural characteristics used for defense against herbivores. Thus, temperature has potentially important implications for host plant resistance. Because temperature directly impacts arthropod pests, both positively and negatively, distinguishing direct effects from indirect effects mediated through host plants poses a challenge for researchers and practitioners. A more comprehensive understanding of how temperature affects plant resistance specifically, and arthropod …

Association Between Sulfur-Metabolizing Bacterial Communities In Stool And Risk Of Distal Colorectal Cancer In Men, Long H. Nguyen, Wenjie Ma, Dong D. Wang, Yin Cao, Himel Mallick, Teklu K. Gerbaba, Jason Lloyd-Price, Galeb Abu-Ali, A. Brantley Hall, Daniel Sikavi, David A. Drew, Raaj S. Mehta, Cesar Arze, Amit D. Joshi, Yan Yan, Tobyn Branck, Casey Dulong, Kerry L. Ivey, Shuji Ogino, Eric B. Rimm, Mingyang Song, Wendy S. Garrett, Jacques Izard, Cutis Huttenhower, Andrew T. Chan

Department of Food Science and Technology: Faculty Publications

Background and aims: Sulfur-metabolizing microbes, which convert dietary sources of sulfur into genotoxic hydrogen sulfide (H₂S), have been associated with development of colorectal cancer (CRC). We identified a dietary pattern associated with sulfur-metabolizing bacteria in stool and then investigated its association with risk of incident CRC using data from a large prospective study of men.

Methods: We collected data from 51,529 men enrolled in the Health Professionals Follow-up Study since 1986 to determine the association between sulfur-metabolizing bacteria in stool and risk of CRC over 26 years of follow-up. First, in a subcohort of 307 healthy men, we …

Integrating The Ecosystem Services Framework To Define Dysbiosis Of The Breastfed Infant Gut: The Role Of B. Infantis And Human Milk Oligosaccharides, Rebbeca M. Duar, Bethany M. Henrick, Giorgio Casaburi, Steven A. Frese

Department of Food Science and Technology: Faculty Publications

Mounting evidence supports a connection between the composition of the infant gut microbiome and long-term health. In fact, aberrant microbiome compositions during key developmental windows in early life are associated with increased disease risk; therefore, making pertinent modifications to the microbiome during infancy offers significant promise to improve human health. There is growing support for integrating the concept of ecosystem services (the provision of benefits from ecosystems to humans) in linking specific microbiome functions to human well-being. This framework is widely applied in conservation efforts of macro-ecosystems and offers a systematic approach to guide restoration actions aimed to recover critical …

Investigating Microbiomes And Developing Direct-Fed Microbials To Improve Cattle Health, Alison C. Bartenslager

Department of Animal Science: Dissertations, Theses, and Student Research

Over the last decade, global beef production has increased to meet the protein needs of the growing population. As a result, the intensification of beef cattle production systems has resulted in broad spectrum prophylactic use of antibiotics and growth promoting agents. With increased concern around antimicrobial resistance (AMR) and emergence of novel pathogenic strains of bacteria, it is critical to understand disease progression and associated changes in the microbiome to develop novel therapeutic alternatives to reduce antibiotic use and control disease. One such approach that is currently being investigated is the development of novel direct-fed microbial strains to outcompete pathogens …

Heat Stress-Induced Deficits In Growth, Metabolic Efficiency, And Cardiovascular Function Coincided With Chronic Systemic Inflammation And Hypercatecholaminemia In Ractopamine-Supplemented Feedlot Lambs: Atypical Cyclicity At Puberty In Beef Cows Is Associated With Early Deficits In Muscling, Metabolic Indicators, And Myoblast Function In Offspring But Does Not Impact Feedlot Performance, Rebecca M. Swanson

Department of Animal Science: Dissertations, Theses, and Student Research

Our 1^st study evaluated the effects of b-adrenergic agonist (ractopamine) supplementation on growth, health, and wellbeing in heat-stressed feedlot wethers. Chronic heat stress impaired growth, metabolism, and wellbeing even when the impact of reduced feed intake was eliminated by pair-feeding. We observed systemic inflammation and hypercatecholaminemia that were likely mediators of these deficits. Moreover, ractopamine did not diminish any wellbeing indicators and improved muscle growth without worsening the effects of heat stress.

Our 2^nd study assessed the effects of pubertal cyclicity (weaning to 1^st breeding) in cows on myoblast-mediated muscle growth, metabolism, and growth efficiency of their …

Comparison Of Comprehensive Health Score In North American Housed Giraffe And Free-Ranging Giraffe From South Africa, Haley Beer

Department of Animal Science: Dissertations, Theses, and Student Research

Stress is evident in many animal species and has been correlated to disease prevalence. During stressful events, allostasis is initiated by physiologic systems to maintain or reestablish homeostasis to protect an organism’s viability. Over time, the acclimation to frequent stress causes systematic dysregulation, leading to the phenomena of increased allostatic load. Allostatic load has been assessed in animal species via serum through selection of representative, multi-system biomarker indices. Perception and number of stress events may impact dysregulation severity, yielding allostatic load as a predictive tool. However, the allostatic load methodology poses application limitations to individuals without historical data and those …

Evaluation Of Protein Sources And Holstein Finishing Systems For Organic Beef Production And A Comparison Of Single And Dual Implant Strategies In Finishing Heifers, Elizabeth A. Schumacher

Department of Animal Science: Dissertations, Theses, and Student Research

Two in situ experiments were conducted to compare the rumen undegradable protein content (RUP) and RUP digestibility of conventional and organic field peas, fish meal, dehydrated alfalfa, and soybean meal. Significant differences were detected between feed samples in both studies for all variables measured. Variation existed between sample types but the data did not suggest that organic and conventional feeds are different when processed with the same methods. A performance experiment was conducted utilizing individually fed Holstein steers comparing the effect of RUP source in a simulated organic production system. Dietary treatments were: no supplemental protein (NONE), field peas (FP), …

Occurrence And Persistence Of Antibiotics Administered To Cattle In A Newly Established Feedlot, Brittany Trejo

Department of Environmental Engineering: Theses and Other Student Research

The common practice of using therapeutic antibiotics in livestock farming is a worldwide phenomenon. Over the last decade, there has been a growing concern of antibiotics entering the environment via animal manure. Similar studies have focused on the occurrence and biological effects of antibiotics in land-applied animal feedlots; however, limited research has been conducted on the occurrence and persistence of antibiotics in animal feedlots. A study was conducted to investigate the occurrence and persistence of four injected antibiotics (ceftiofur enrofloxacin, florfenicol, and tulathromycin) and two continuously fed antibiotics (monensin and tylosin) in feedlot sediment, runoff, and sediment runoff. For antibiotics …

Caloric Restriction Induces Anabolic Resistance To Resistance Exercise, Chaise Murphy, Karsten Koehler

Department of Nutrition and Health Sciences: Faculty Publications

Purpose Weight loss can result in the loss of muscle mass and bone mineral density. Resistance exercise is commonly prescribed to attenuate these effects. However, the anabolic endocrine response to resistance exercise during caloric restriction has not been characterized. Methods Participants underwent 3-day conditions of caloric restriction (15 kcal kg FFM⁻¹) with post-exercise carbohydrate (CRC) and with post-exercise protein (CRP), and an energy balance control (40 kcal kg FFM⁻¹) with post-exercise carbohydrate (CON). Serial blood draws were taken following five sets of five repetitions of the barbell back squat exercise on day 3 of each condition. …

Diabetes Debunked: What You Need To Know, Maggie Hutson

Honors Program: Senior Projects (Public)

The goal of this Honors creative project is to encourage health literacy in populations who are curious about Type 2 Diabetes or have Type 2 Diabetes. From personal experience, I have seen noncompliance in diabetics and wondered why since it is a serious, progressive disease. After researching, I found that some diabetics do not understand the scope of their disease, especially since many of the dangerous complications that arise from Type 2 Diabetes do not present until later in the disease when it is too late. For my senior project, I decided to write an educational paper as a supplement …

Neutrophil Infiltration Into The Cervical Compartment Is Suppressed By Hiv Infection, Madeline Maschka

Honors Program: Senior Projects (Public)

Human Papillomavirus (HPV), is a small circular dsDNA virus with at least 200 different genotypes; each genotype is identified by at least 10% difference at the DNA level in the L1 capsid gene. Each HPV genotype affects the body in different tissues, either mucosal or cutaneous. Mucosal HPVs type 16 and 18 are known as high-risk strains, since HPV infection is the most common cause of cervical cancer and plays a central role in formation of precancerous lesions. Human immunodeficiency virus (HIV) damages the body’s immune system by targeting CD4+ T cells. Once CD4+ T cells are infected, the body …

The Unique Demands Of Playing Posture On Youth Violinists And Violists, Liam Carroll

Honors Program: Senior Projects (Public)

The high prevalence of performing arts injuries is an acknowledged challenge facing the performing arts medicine community. The injuries seem to affect string players the most among orchestral musicians, specifically violinists and violists. The asymmetrical posture, head and neck displacement, and spinal displacement required by the posture to play violin and viola can lead to discomfort or injury in the performer. Performance related musculoskeletal disorders (PRMDs) can have an adverse impact on the life of a musician, preventing them from performing or making it uncomfortable. While there is a large body of research on PRMDs relating to adult musicians, there …
