At The First Table, Jodi Campbell

University of Nebraska Press: Sample Books and Chapters

Research on European food culture has expanded substantially in recent years, telling us more about food preparation, ingredients, feasting and fasting rituals, and the social and cultural connotations of food.

At the First Table demonstrates the ways in which early modern Spaniards used food as a mechanism for the performance of social identity. People perceived themselves and others as belonging to clearly defined categories of gender, status, age, occupation, and religion, and each of these categories carried certain assumptions about proper behavior and appropriate relationships with others. Food choices and dining customs were effective and visible ways of displaying these …

Varicella Seroepidemiology In United States Air Force Recruits: A Retrospective Cohort Study Comparing Immunogenicity Of Varicella Vaccination And Natural Infection, Joshua R. Duncan, Catherine T. Witkop, Bryant J. Webber, Amy A. Costello

Uniformed Services University of the Health Sciences

Background/Objectives: Infection with varicella zoster virus (VZV) produces lifelong immunity, but duration of post-vaccination immunity has not been established. The purpose of this study is to determine if a difference exists in the long-term seropositivity of anti-VZV antibodies in a cohort of young adults who were vaccinated against varicella as compared to a similar cohort with a history of chickenpox disease, and to determine which variables best predict waning seropositivity following varicella vaccination.

Methods: This retrospective cohort study captures immunization and serology data from approximately 10,000 recruits who entered basic military training between January 1, 2008, and December 31, 2015, …

Examination Of The Interpersonal Model Of Loss Of Control Eating In The Laboratory, Lisa M. Shank, Ross D. Crosby, Anne Claire Grammer, Lauren B. Shomaker, Anna Vannucci, Natasha L. Burke, Monika Stojek, Sheila M. Brady, Merel Kozlosky, James C. Reynolds, Jack A. Yanovski, Marian Tanofsky-Kraff

Uniformed Services University of the Health Sciences

Background: The interpersonal model of loss of control (LOC) eating proposes that interpersonal problems lead to negative affect, which in turn contributes to the onset and/or persistence of LOC eating. Despite preliminary support, there are no data examining the construct validity of the interpersonal model of LOC eating using temporally sensitive reports of social stress, distinct negative affective states, and laboratory energy intake.

Method: 117 healthy adolescent girls (BMI: 75th–97th %ile) were recruited for a prevention trial targeting excess weight gain in adolescent girls who reported LOC eating. Prior to the intervention, participants completed questionnaires of recent social stress …

Association Of A Frailty Screening Initiative With Postoperative Survival At 30, 180, And 365 Days, Daniel E. Hall, Shipra Arya, Kendra K. Schmid, Mark A. Carlson, Pierre Lavedan, Travis L. Bailey, Georgia Purviance, Tammy Bockman, Thomas G. Lynch, Jason M. Johanning

United States Department of Veterans Affairs: Publications

IMPORTANCE As the US population ages, the number of operations performed on elderly patients will likely increase. Frailty predicts postoperative mortality and morbidity more than age alone, thus presenting opportunities to identify the highest-risk surgical patients and improve their outcomes.

OBJECTIVE To examine the effect of the Frailty Screening Initiative (FSI) on mortality and complications by comparing the surgical outcomes of a cohort of surgical patients treated before and after implementation of the FSI.

DESIGN, SETTING, AND PARTICIPANTS This single-site, facility-wide, prospective cohort quality improvement project studied all 9153 patients from a level 1b Veterans Affairs medical center who presented …

A System-Level Approach To Overweight And Obesity In The Veterans Health Administration, Susan D. Raffa, Matthew L. Maciejewski, Lindsey E. Zimmerman, Larua J. Damschroder, Paul A. Estabrooks, Ronald T. Ackermann, Adam G. Tsai, Trina Histon, Michael G. Goldstein

United States Department of Veterans Affairs: Publications

Healthcare systems are challenged by steady increases in the number of patients who are overweight and obese. Large-scale, evidence-based behavioral approaches for addressing overweight and obesity have been successfully implemented in systems such as the Veterans Health Administration (VHA). These population-based interventions target reduction in risk for obesity-associated conditions through lifestyle change and weight loss, and are associated with modest weight loss. Despite the fact that VHA has increased the overall reach of these behavioral interventions, the number of high-risk overweight and obese patients continues to rise. Recommendations for weight loss medications and bariatric surgery are included in clinical practice …

Steroids: A Growing Dilemma In Athletics, Seara Ontiveros

Nebraska College Preparatory Academy: Senior Capstone Projects

A comprehensive and straight forward description of what exactly steroids are and what they do to the body is described by Gary Wadler, a health major at the New York University School of Medicine, he comments: “When the receptor sites in their bodies, which don’t have much testosterone in them, suddenly are presented with a lot of testosterone, they get activated…The unbalance of hormones increases the red blood cell formations... They’ll get more muscular, more defined. They’ll lose some fat, and increase their lean body mass, [they’ll] get stronger”. Although anabolic steroids and other hormones are consumed by many athletes …

Evaluating The Impact Of An Exotic Plant Invasion On Rodent Community Richness And Abundance, Trinity N. Smith, Eric M. Gese, Bryan M. Kluever

United States Department of Agriculture Wildlife Services: Staff Publications

Cheatgrass (Bromus tectorum), Russian thistle (Salsola kali), and tall tumblemustard (Sisymbrium altissimum) are nonnative plants widely distributed throughout the desert and shrubsteppe communities of the western United States. The impact of these invaders on plant community structure, form, and function has been well documented, but investigations determining the impacts of this cumulative invasion on terrestrial vertebrates have not been undertaken. Our objective was to assess community-level rodent responses to changes in plant community features, with an emphasis on dominance of invasive plant species. We sampled rodent and plant communities in the Great Basin Desert …

Estimating The Number Of Recreational Anglers For A Given Waterbody, Kevin L. Pope, Larkin A. Powell, Brian S. Harmon, Mark A. Pegg, Christopher J. Chizinski

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Knowing how many anglers use a given body of water is paramount for understanding components of a fishery related to angling pressure and harvest, yet no study has attempted to provide an estimate of the population size of anglers for a given waterbody. Here, we use information from creel surveys in a removal-sampling framework to estimate total numbers of anglers using six reservoirs in Nebraska, USA, and we examine the influence of the duration of sampling period on those estimates. Population estimates (N ± SE) of unique anglers were 2050 ± 45 for Branched Oak Lake, 1992 ± 29 for …

Is Economic Inequality Really A Problem? A Review Of The Arguments, E. Wesley F. Peterson

Department of Agricultural Economics: Faculty Publications

Increasing economic inequality in recent years has triggered an outpouring of analysis and reflection on the causes and consequences of these changes. Several commentators have argued that inequality does not merit all the attention it has been receiving noting that the focus on inequality can divert attention from the real problem, which is poverty. This article reviews the arguments for and against this position, highlighting the effects of economic inequality on economic growth and efficiency, politics and democracy, individual behaviors that result in poor health outcomes and social disruption, social cohesion, and environmental degradation. Poverty is, of course, a very …

Impact Of Schoolchildren’S Involvement In The Design Process On The Effectiveness Of Healthy Food Promotion Materials, Christopher Gustafson, Bryce M. Abbey, Kate A. Heelan

Department of Agricultural Economics: Faculty Publications

Marketing techniques may improve children's vegetable consumption. However, student participation in the design of marketing materials may increase the material's salience, while also improving children's commitment and attitudes towards healthy eating.

The impact of student-led design of vegetable promotional materials on choice and consumption was investigated using 1614 observations of students' vegetable choice and plate waste in four public elementary schools in Kearney, Nebraska. Data were collected on children's vegetable choice and consumption in four comparison groups: 1) control; 2) students designed materials only; 3) students were exposed to promotional materials only; and 4) students designed materials that were then …

West Central Research and Extension Center, North Platte

Biochar, a byproduct from the biofuels industry, may be a potential feed additive in ruminant diets due to possible improvements in microbial fermentation. Therefore, the objective of this study was to determine the nutritive value, in vitro digestibility, volatile fatty acid (VFA) production, and gas production of biochar inclusion to an orchard grass (Dactylis glomerata) basal diet. The study was designed as a 3 × 2 factorial arrangement with 3 different biochar sources and 2 biochar processed sizes as the main effects factors. Experimental treatments were biochar from 3 different tree types: 1) Chestnut Oak (Quercus prinus …

Do Movement Patterns Of Gps-Tracked Cattle On Extensive Rangelands Suggest Independence Among Individuals?, Mitchell B. Stephenson, Derek W. Bailey

Panhandle Research and Extension Center

In behavioral studies, cattle within the same pasture are not considered as independent experimental units because of the potential confounding effects of the herd’s social interactions. However, evaluating cattle behavior on extensive rangelands is logistically challenging for researchers, and treating individual animals as independent experimental units may be beneficial for answering specific research questions. The objective of this study was to evaluate the association patterns among global positioning system (GPS)-tracked cattle at six different study sites in the western United States. A Half-Weight Index (HWI) association value was calculated for each pair of GPS-tracked cows (i.e., dyad) to determine the …

A Guidebook On Honey Bee Health: Honey Bee Immunity — Pesticides — Pests And Diseases, Joey Caputo

Department of Entomology: Distance Master of Science Projects

Pedigo and Rice (2009) described a concept that some ecologists subscribe to called the “balance of nature” phenomenon. This idea holds that spe-cies in communities achieve certain status in their ecosystem and that this status becomes fixed and resistant to change. On average, individuals are only able to replace themselves. Fluctuations may occur, but ultimately the various species in the community will retain their position and relative population size in the ecosystem. According to these ecologists, when humans alter and reduce the diversity of an ecosystem they are acting counter to this balance. In an attempt to re-turn the altered …

Trends Of Lack Of Health Insurance Among Us Adults Aged 18-64 Years: Findings From The Behavioral Risk Factor Surveillance System, 1993-2014, G. Zhao, C. A. Okoro, S. S. Dhingra, F. Xu, M. Zack

United States Public Health Resources

Objective: To examine the prevalence of lack of health insurance and its changes over time among adult residents (aged 18-64 years) in 50 states and the District of Columbia (DC).

Study design: Cross-sectional surveys.

Methods: We aggregated annual state-based Behavioral Risk Factor Surveillance System (BRFSS) data from 1993 through 2014 to provide nationwide and state-based prevalence estimates for lack of insurance among adults aged 18-64 years. The adjusted prevalence was estimated using log-linear regression analyses with a robust variance estimator after controlling for demographic variables. The trend was assessed separately for the periods 1993-2010 and 2011-2014 due to methodologic changes …

Acute Maternal Oxidant Exposure Causes Susceptibility Of The Fetal Brain To Inflammation And Oxidative Stress, Feroz Akhtar, Christopher A. Rouse, Gabriel Catano, Marcus Montalvo, Sarah L. Ullevig, Reto Asmis, Kusum K. Kharbanda, Shivani K. Maffi

United States Public Health Resources

Background: Maternal exposure to environmental stressors poses a risk to fetal development. Oxidative stress (OS), microglia activation, and inflammation are three tightly linked mechanisms that emerge as a causal factor of neurodevelopmental anomalies associated with prenatal ethanol exposure. Antioxidants such as glutathione (GSH) and CuZnSOD are perturbed, and their manipulation provides evidence for neuroprotection. However, the cellular and molecular effects of GSH alteration in utero on fetal microglia activation and inflammation remain elusive.

Methods: Ethanol (EtOH) (2.5 g/kg) was administered to pregnant mice at gestational days 16–17. One hour prior to ethanol treatment, N-acetylcysteine (NAC) and L-buthionine sulfoximine (BSO) …

Department of Nutrition and Health Sciences: Faculty Publications

The purpose of the present study was to examine the effects of 2 different work-to-rest ratios, but the same mean load, cycle time, and total duration of the exercise bout, on maximal voluntary isometric contraction torque and neuromuscular responses to fatiguing, intermittent, submaximal, isometric, forearm flexion muscle actions. Ten men performed 2 fatiguing protocols with different work-to-rest ratios (4 s contraction, 4 s rest vs. 4 s contraction, alternating 6 and 2 s rest) that consisted of 50 intermittent, submaximal (65% of maximal voluntary isometric contraction), isometric, forearm flexion muscle actions. Electromyographic and mechanomyographic signals from the biceps brachii were …

Effects Of Fatigue And Recovery On Electromechanical Delay During Isokinetic Muscle Actions, Cory M. Smith, Terry J. Housh, Ethan C. Hill, Josh L. Keller, Glen O. Johnson, Richard J. Schmidt

Department of Nutrition and Health Sciences: Faculty Publications

Objective: To examine muscle-specific differences and the effects of fatigue and recovery on electromechanical delay (EMD) during maximal isokinetic muscle actions.

Approach: Thirteen men performed maximal isokinetic knee extension muscle actions at 60° s⁻¹, pretest, posttest, and after 5 min of recovery from 25 maximal isokinetic knee extensions. The onsets of the electromyographic, mechanomyographic, and force signals were used to identify EMD measures from the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF).

Main results: There were posttest increases in all EMD measures for all muscles that returned to pretest levels after 5 …

Formation Of Polyphenol-Denatured Protein Flocs In Alcohol Beverages Sweetened With Refined Cane Sugars, Gillian Eggleston, Alexa Triplett

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The sporadic appearance of floc from refined, white cane sugars in alcohol beverages remains a technical problem for both beverage manufacturers and sugar refiners. Cane invert sugars mixed with 60% pure alcohol and water increased light scattering by up to ~1000-fold. Insoluble and soluble starch, fat, inorganic ash, oligosaccharides, Brix, and pH were not involved in the prevailing floc formation mechanism. Strong polynomial correlations existed between the haze floc and indicator values I.V. (color at 420 nm pH 9.0/color at pH 4.0 - an indirect measure of polyphenolic and flavonoid colorants) (R²=0.815) and protein (R² =0.819) content …

Physical, Rheological, Functional, And Film Properties Of A Novel Emulsifier: Frost Grape Polysaccharide From Vitis Riparia Michx, William T. Hay, Steven F. Vaugh, Jeffrey A. Byars, Gordon W. Selling, Derek M. Holthaus, Neil P.J. Price

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A novel emulsifier, Frost grape polysaccharide (FGP), isolated from natural exudate of the species Vitis riparia Michx, was physically and rheologically characterized. The determination of the physical, structural, thermodynamic, emulsification, film, and rheological properties of FGP provide essential details for the commercial adoption of this novel plant polysaccharide. FGP is capable of producing exceptionally stable emulsions when compared with the industrially ubiquitous gum arabic (GA). The FGP isolate contained a negligible amount of nitrogen (0.03%), indicating that it does not contain an associated glycoprotein, unlike GA. Solutions of FGP have a high degree of thermostability, displaying no loss in viscosity …

The Effect Of Supplementing Mannan Oligosaccharide Or Finely Ground Fiber, During The Summer On Body Temperature, Performance, And Blood Metabolites Of Finishing Steers, Bradley M. Boyd, Terry L. Mader, Curtis J. Bittner Bittner, Henry Hilscher, Gene Wijffels, John B. Gaughan, Megan Sullivan, Judy Cawdell- Smith, Galen E. Erickson

Nebraska Beef Cattle Reports

Crossbred beef steers (12 pens, n=96) were used to determine the effect of adding Agrimos or 5% ground (1 in.) wheat straw compared to a control on body temperature, panting score and performance. Th ere were no differences in final BW, ADG, and DMI among treatments. Feed conversion was increased for cattle fed 5% additional ground straw when compared to control and Agrimos. Hot carcass weight, dressing %, LM area, and marbling score were not different among treatments. Cattle fed the control had greater 12th rib fat depth and USDA yield grade than cattle fed straw or Agrimos. Both average …

Comparison Of Diets Collected From Esophageally Fistulated Cows To Forage Quality Estimated From Fecal Analysis, Bethany M. Johnston, Jay D. Jenkins, Jacqueline A. Musgrave Musgrave, L. A. Stalker, Mitchell B. Stephenson

Nebraska Beef Cattle Reports

Differences in forage quality (crude protein and energy) were analyzed between esophageally fistulated diets, analysis of fecal samples with Nutrition Balance Analyzer (NUTBAL) analysis, and analysis of handclipped forage samples. On upland range sites, hand- clipped samples provided forage quality estimates that were closer to esophageally fistulated diets than samples analyzed with the NUTBAL analysis. Aft er one year of data collection, it appears that there may be some inconstancies with the NUTBAL analysis for estimates on rangeland forage quality in the Nebraska Sandhills. More data is needed to verify these results; however, making management supplementations decisions solely on the …

Evaluation Of Plant- Waxes To Estimate Forage Intake In Grazing Cattle, Hannah C. Hamilton, Jerry D. Volesky, Robert M. Lewis Lewis

Nebraska Beef Cattle Reports

Although key to the efficiency of a cattle operation, feed intake is challenging to evaluate in a grazing setting. However, even within forage- based systems, plant- wax markers may be used to predict dietary choices and feed intake. Plant- waxes are a complex mixture of lipids found on the surface of plants. When sufficiently unique among plants, the composition of diets can be determined from the pattern of these compounds in the forages ingested. These markers were used to delineate the parts of the corn plant and, separately, 8 western rangeland grasses and legumes. Using plant waxes, the components of …

Fatty Acid Composition Of Beef Fed Omnigen- Af At Receiving Or Finishing, Katherine I. Domenech, Michael D. Chao, Joe O. Buntyn Buntyn, Ty B. Schmidt, Chris Calkins

Nebraska Beef Cattle Reports

Beef fatty acid profiles and superoxide dismutase activity were determined for cattle receiving OmniGen- AF supplementation (a patented nutritional supplement) at receiving (first 28 d at the feedlot) or throughout finishing (all 210 d of finishing) vs. a control group (non- supplemented). Th e most meaningful change in fatty acid composition from inclusion of OmniGen- AF was total poly- unsaturated fatty acid (PUFA) content where beef from the finishing group had more PUFA content in relation to the receiving group and was not different from the control group. Despite this increase in PUFA, cattle supplemented through finishing tended to have …

Effect Of Backgrounding System On Steer Performance And Carcass Characteristics, Jordan L. Cox, Kristin E. Hales, Kristen M. Ulmer Ulmer, Richard J. Rasby, Steven D. Shackleford, Chad Engle, John Rieckman, Harvey C. Freetly, Mary Drewnoski

Nebraska Beef Cattle Reports

The impact of 3 backgrounding systems: grazing corn residue with distillers grains supplementation at 0.86% BW/d, grazing an oats-brassica forage, or feeding a grower ration in a drylot on finishing performance and carcass characteristics were evaluated. Backgrounding phase gains were greatest for steers fed a grower ration in the drylot (3.58 lb/d), intermediate for steers grazing oats-brassica forage and then fed the grower ration for short period (2.65 lb/d), and least for steers grazing corn residue while supplemented distillers grains and then fed the grower ration for short period (2.22 lb/d). These backgrounding treatment differences did not affect ADG during …

Growth And Reproductive Performance Of Yearling Beef Heifers Implanted With Revalor G In The Nebraska Sandhills, Benjamin T. Tibbitts, Hazy Rae Nielson, K. H. Ramsay Ramsay, Richard N. Funston

Nebraska Beef Cattle Reports

Th is study evaluated effects of a single stocker implant (Revalor G) on growth and reproductive performance of yearling beef heifers in the Nebraska Sandhills. Crossbred heifers, grazing native Sandhills range, were randomly assigned to either be implanted 82 ± 2 days prior to estrus synchronization, or not implanted, to determine the effects of growth implants on heifer performance. Heifers were bred via artificial insemination followed with clean- up bulls. Implanted heifers gained more and were heavier at the end of the trial, but had a reduced pregnancy rate than non- implanted heifers. Implanted heifers also had a lower pregnancy …

Impact Of Heifer Development System In Two Different Breeding Seasons, Shelby A. Springman, Hazy Rae Nielson, Jacqueline A. Musgrave Musgrave, John Nollette, Andy Applegarth, Richard N. Funston

Nebraska Beef Cattle Reports

Replacement heifers from March and May calving herds were offered ad libitum meadow hay and 4 lb/d supplement or grazed meadow and offered 1 lb/d supplement from mid- January to mid- April. Heifers fed hay gained more during the treatment; however, heifers grazing meadow experienced compensatory gain, resulting in similar body weight at pregnancy diagnosis in both calving herds. Pregnancy rates were similar between treatment groups in March and May heifers. A reduced input winter management system is a viable option to maintain pregnancy rates in early and late summer breeding seasons.
