The Association Of Wellness Policy Quality And Percentage Of Obesity In Schools, Bryce M. Abbey

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

Schools possess a unique opportunity to reach a large captive audience and are becoming one of the battlegrounds for childhood obesity. To address the school environment’s role on the influence of American children’s nutritional intake and participation in physical activity, the United States (US) Federal Government adopted the Healthy, Hunger-Free Kids Act of 2010, placing an emphasis on implementation of the local school wellness policy (LSW). The purpose of this study was to examine the association between LSW and percentage of obesity in school districts within Nebraska. Aggregate district-wide body mass index (BMI) percentile data were utilized from previously collected …

Psychosocial Food-Related Behavior And Food Intake Of Adult Main Meal Preparers Of Food For 9-10 Year-Old Children Participating In Icook, A Five-State Childhood Obesity Pilot Prevention Study, Ashley A. Miller

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

Understanding adult outcomes of programs aimed at childhood obesity prevention is necessary because parents/caregivers are the most important influence on a child’s physical activity and eating habits. Based on the principles of the social cognitive theory, the iCook 4-H pilot study taught dyads consisting of 9-10 year-old children and their primary meal preparers cooking skills, healthy shopping and meal habits, and easy ways to incorporate physical activity as a family. The program took place in five states, Maine, Nebraska, South Dakota, Tennessee, and West Virginia. In each state, adult-youth dyads (n = 54) were recruited by 4-H programs and nutrition …

First the anti-adherence activity of MOS and their purified fraction (pMOS) was tested against three strains of C. jejuni and two strains of C. coli. Results shown significant reductions in adherence (up to 70%) …

Perceived Impacts Of A Public Health Training Center Field Placement Program Among Trainees: Findings From A Small Group Externship Experience, Patrik Johansson, Brandon Grimm, Tarik Abdel-Monem, Stacey J. Hoffman, Mark Dekraai, Analisa Mcmillan

University of Nebraska Public Policy Center: Publications

There is heightened interest in identifying the impact of the federally funded Public Health Training Center (PHTC) program. Although evaluation studies have been conducted of public health training in general, evaluations of PHTC programs are rare. Field placement components are congressionally mandated requirements of PHTCs. Field placements are typically intensive, supervised externships for students to gain public health experience with local health departments or non-profit organizations. We have found no published evaluations of PHTC field placement components. This may be because of their small size and unique nature. We designed and evaluated a 200-h field placement program at an established …

Summers, Tracey R. Spoon, Judy A. St. Leger, Caroline E. C. Goertz, J. Lawrence Dunn, Tracy A. Romano, Roderick C. Hobbs, Allison D. Tuttle

United States Department of Commerce: Staff Publications

Thyroid hormones play a critical physiologic role in regulating protein synthesis, growth, and metabolism. To date, because no published compilation of baseline values for thyroid hormones in beluga whales (Delphinapterus leucas) exists, assessment of thyroid hormone concentrations in this species has been underused in clinical settings. The purpose of this study was to document the concentrations of total thyroxine (tT4) and total triiodothyronine (tT3) in healthy aquarium-maintained and free-ranging beluga whales and to determine the influence of age, sex, and season on the thyroid hormone concentrations. Archived serum samples were collected from healthy aquarium-maintained (n = 43) …

Feeding Alkaline Treated And Processed Crop Residue To Feedlot Cattle, Sarah Jean Peterson

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

Chemical treatment and decreased particle size are methods used to improve digestibility and utilization of the available nutrients in low quality forages. Previous research has indicated that chemically treated corn residue can take the place of corn when included in finishing rations containing distillers grains. Also, decreasing particle size utilizing methods such as pelleting has been shown to improve DMI and ADG. However, limited research has been completed on use of chemical treatment and pelleting in growing and receiving rations. Also, an ideal distillers inclusion has not yet been identified when including alkaline treated stalks in finishing rations. Therefore, a …

Functional Genomics Of Maize Endosperm Maturation And Protein Quality, Lingling Yuan

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Maize is one of the most important cereal crops and widely cultivated throughout the world. The study on maize kernel development including protein quality improvement is essential for removing dietary protein deficiency because of the lack of essential amino acids, especially lysine and tryptophan, in maize kernel. Quality Protein Maize (QPM) is a hard kernel variant of the high-lysine mutant, opaque-2. We created opaque QPM variants to identify opaque-2 modifier genes and to investigate deletion mutagenesis combined with Illumina sequencing as a maize functional genomics tool. A K0326Y-QPM deletion mutant, line 107, was null for the 27- and 50-kD …

Non-Digestible Oligosaccharides: Anti-Adherence And Other Biological Properties, Maria I. Quintero-Villegas

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Bacterial adherence is the first and one of the most important steps in bacterial pathogenesis. Adherence to host cell surfaces requires that the bacteria recognize specific receptors in the surface of epithelial cells. Therefore, agents that act as molecular decoys to interfere with adherence could be useful prophylactic treatments to prevent or mitigate the onset of infections. The goal of this research was to assess the ability of several food grade non-digestible oligosaccharides (NDOs) to act as molecular decoys and prevent bacterial adherence in vitro as well as in vivo. First, the antiadherence effect of specific species chitooligosaccharides (CHOS) …

Characterization Of Genetically Modified High Biomass Producing Tobacco Plant, Pankaj Singh Kuhar

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

Global warming and peak oil has clouded our energy security. In light of this situation, bioethanol as emerged as one of the most amenable solutions to the problem. However bioethanol has its own shortcomings and transgenics seem imperative to exploit its full potential. A high biomass producing line in transgenic tobacco (Nicotiana tabacum cv. Xanthi) was identified during a routine genetic transformation, termed giant recombinant (GR). To characterize the phenotype of the giant line, growth rate and lignocellulosic composition was analyzed relative to the non-transgenic control line. The GR line accounted for 240% more biomass than the untransformed line …

Gmos: Are They A Regulatory Or Food Safety Issue?, Richard E. Goodman

Department of Food Science and Technology: Faculty Publications

Most of the genetic diversity that has improved agricultural production throughout the history of farming was developed through natural mutations and selective breeding. However, since the early 1900s plant scientists have used chemical and radiation mutagenesis to increase genetic diversity (18). We know that the majority of mutations are harmful, and plant breeders work hard to select only those that are beneficial. This process has helped feed a growing human population, which is estimated to have been 300 million 2,000 years ago and is now more than 7 billion. However, methods used in the past to improve agricultural production are …

Existing crop monitoring programs determine the incidence and distribution of plant diseases and pathogens and assess the damage caused within a crop production region. These programs have traditionally used observed or predicted disease and pathogen data and environmental information to prescribe management practices that minimize crop loss (3,69). Monitoring programs are especially important for crops with broad geographic distribution or for diseases that can cause rapid and great economic losses. Successful monitoring programs have been developed for several plant diseases, including downy mildew of cucurbits, Fusarium head blight of wheat, potato late blight, and rusts of cereal crops (13,36,51,80).

Environmental Management Of Threatening Government Public Policy, Jess Mikeska

College of Business: Dissertations, Theses, and Student Research

This dissertation is the first to propose a test of environmental management theory through a reflective, managerial scale, and does so through a public policy lens. It matches 76 managerial respondents’ (17 firms) perceptions of environmental management with objective, secondary data ranging between 2002 and 2014 so as to reflect longitudinal changes in marketplace activities which influence end consumers (e.g., pricing, promotional activity). Such changes are artifacts of firms’ environmental management of threatening government public policy.

The findings of two studies, qualitative interviews based on a transcendental phenomenological design and an online survey matched to secondary marketplace data utilizing Hierarchical …

Application Of Nuclear Magnetic Resonance Based Metabolomics To Study The Central Metabolism Of Staphylococci, Bo Zhang

Department of Chemistry: Dissertations, Theses, and Student Research

Metabolomics studies the collection of small molecules (metabolites) involved in enzymatically catalyzed reactions, cell signaling and cellular structure. Perturbations in metabolite concentrations have been used to reflect the activity of corresponding enzymes or proteins. Nuclear magnetic resonance (NMR) spectroscopy is a well-known approach for the structure determination of biological macromolecules. Alternatively, NMR has recently been established as a valuable tool of metabolomics, in which NMR spectral signals correlate small molecules with cellular activities. This has been accomplished through the chemometric analysis of high-throughput one dimensional ¹H spectra (metabolic fingerprinting) and quantitative metabolite identification based on two dimensional ¹H, …

Patch-Burn Grazing Effects On Cattle Performance: Research Conducted In A Working Landscape, Stephen L. Winter, Samuel D. Fuhlendorf, Mark Goes

School of Natural Resources: Faculty Publications

• Patch-burn grazing is a range management strategy that might be able to simultaneously optimize livestock production objectives and wildlife habitat objectives.

• We compared patch-burn grazing to a traditional range management strategy in multiple pastures, representing a variety of land ownership and management histories, dispersed across a relatively large geographic area. Our results likely represent what land managers could expect if they adopted patch-burn grazing in similar situations.

• We found that cattle performance in pastures managed with patch-burn grazing did not differ from that found in pastures managed with a traditional range management strategy. This suggests that land …

Chlorovirus Skp1 And Core Ankyrin-Repeat Protein Interplay And Mimicry Of Cellular Ubiquitin Ligase Machinery, Eric Andrew Noel

School of Biological Sciences: Dissertations, Theses, and Student Research

The ubiquitin-proteasome system is a common target of several unrelated viruses that have evolved convergent strategies to redirect host ubiquitin machinery to serve their own needs. Members of the genus Chlorovirus, a group of large dsDNA viruses that infect certain freshwater chlorella-like green algae, encode a conserved Skp1 homolog and ankyrin-repeat (ANK) proteins, some of which contain C-terminal domains characteristic of cellular F-boxes or related viral PRANC domains. These observations suggested that this unique combination of chlorovirus proteins either interact with or imitate the key components of the SCF (Skp1-Cul1-F-box) ubiquitin ligases. Using mass spectrometry, we identified two functional …

Harvest Incentives: A Tool For Managing Aquatic Invasive Species, Bob Wiltshire, Nathan Stone, Marshall Meyers, Bill Hyatt, Lori Williams, Jason Goldberg, Susan Pasko, Leah Elwell

National Invasive Species Council

Conclusion

The success of any harvest incentive program to address aquatic invasive species will depend upon numerous biological, socioeconomic, and legal considerations. Programs that encourage harvest may be a successful management tool in targeting small, distinct populations; in high priority areas within a larger invasion; or they may play a supplementary role within larger control programs. Their use, however, will require careful review, planning, and monitoring to ensure success and that they do not unintentionally lead to further spread of invasive species, cause additional harm to native species, or waste valuable resources.

Reprogramming Inner Suburbs, Matthew D. Goeser

Architecture Masters of Science Program: Theses

The ramifications of suburban sprawl and the American dream are widespread and numerous. In a modern society where the preconditioned value of a three-car garage, large, private backyard and detachment from the city center outweighs the possible shortcoming of suburbia, there is an increasing need to reevaluate the way in which our cities grow. With suburbia already having a strong footing in the way that modern America operates, we have come to an age where it is more feasible to mend our cities through suburban intervention than reshape the entire system of American values. Urban sprawl has become a matter …

Comparison Of Wet Or Dry Distillers Grains Plus Solubles To Corn As An Energy Source In Forage Based Diets And In Vitro Forage Standard Development Based On In Vivo Digestibilities Utilizing Brome Hay, Prairie Hay And Meadow Hay, Nerissa Ann Ahern

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

Four growing experiments were conducted to evaluate the use of dry rolled corn (DRC) and either dry (DDGS) or wet distillers grains plus solubles (WDGS) as energy sources in high forage diets. In Exp. 1, steers were fed a blend of sorghum silage and alfalfa hay and supplemented 1 of 4 inclusions of WDGS, DDGS or a MIX (67% WDGS: 33% Straw). In Exp. 2, Exp. 3 and Exp. 4, steers were fed diets including WDGS, DDGS or DRC at different inclusions, replacing sorghum silage and grass hay. In Exp. 1, WDGS, DDGS and MIX produced greater ending BW, ADG …
