Sport, Philosophy, And Good Lives, Randolph Feezell Apr 2013

Sport, Philosophy, And Good Lives, Randolph Feezell

University of Nebraska Press: Sample Books and Chapters

There’s more to sports than the ethos of competition, entertainment, and commercialism expressed in popular media and discourse. Sport, Philosophy, and Good Lives discusses sport in the context of several traditional philosophical questions, including: What is a good human life and how does sport factor into it? To whom do we look for ethical guidance? What makes human activities or projects meaningful? Randolph Feezell examines these questions along with other relevant topics in the philosophy of sport such as the contribution of play to a meaningful life, the various reasons for pessimistic views of sport, the various claims that celebrated …

A Mixed Methods Approach To Evaluate Kidquest, A Traditional Classroom Obesity Prevention Intervention, In An Afterschool Program: A Pilot Study, Amy M. Wehbe

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

Over 1.4 million middle school adolescents participate in afterschool programs each year. While most of the obesity prevention interventions focus on the traditional school day, the afterschool setting should not be overlooked. A pilot study was conducted using KidQuest, a traditional classroom nutrition and physical activity intervention for early adolescents ages 10 to 12 based on the social cognitive theory, in an afterschool setting. The purpose of the pilot study was to evaluate the effectiveness of using a nutrition and physical activity intervention developed for the traditional school day in an afterschool setting. The desired outcome of this mixed-methods study …


Assessment Of The Nutrition And Physical Activity Education Needs Of Child Care Providers Across Nebraska, Tracy C. Delaney Apr 2013

Assessment Of The Nutrition And Physical Activity Education Needs Of Child Care Providers Across Nebraska, Tracy C. Delaney

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

Studies estimate 82% of children less than six years of age in the United States are enrolled in non-parental care outside of their home (1). In Nebraska 4,106 child care providers hold licensure (2). This unique child care environment offers opportunity to address food related challenges facing young children. The purpose of this study is to assess the nutrition and physical activity practices provided for children, self-efficacy, and perceived needs of child care providers across Nebraska. A gap in knowledge exist for practices of child care providers in Nebraska and the impact of Child and Adult Care Food Program (CACFP), …

Ruzicka, Tamara Edmonds-Tibbett, Jonathan M. H. Durkin, Louise E. Jackson, F. Andrew Smith, Daniel P. Schachtman, Sally E. Smith, Susan J. Barker

Department of Agronomy and Horticulture: Faculty Publications

Arbuscular mycorrhizal (AM) symbiosis in vascular plant roots is an ancient mutualistic interaction that evolved with land plants. More recently evolved root mutualisms have recruited components of the AM signaling pathway as identified with molecular approaches in model legume research. Earlier we reported that the reduced mycorrhizal colonization (rmc) mutation of tomato mapped to chromosome 8. Here we report additional functional characterization of the rmc mutation using genotype grafts and proteomic and transcriptomic analyses. Our results led to identification of the precise genome location of the Rmc locus from which we identified the mutation by sequencing. The rmc …

How Does A Mom's Nutrition Affect Her Children's Health?, Robert A. Waterland, Marcia Wood Mar 2013

How Does A Mom's Nutrition Affect Her Children's Health?, Robert A. Waterland, Marcia Wood

Agricultural Research Magazine

In some rural villages of the tiny West African nation of The Gambia, food is generally less available during August and September—the peak of the rainy season—than during a typically dry March through May. Now, a study led by molecular geneticist Robert A. Waterland of the USDA-ARS Children’s Nutrition Research Center in Houston, Texas, has shown that functioning of certain genes in kids conceived during the rainy season differs from that in children conceived during the dry season.

The difference may be explained by a relatively new science referred to as “epigenetics.” The variation appears to be permanent, and in …

Americans everywhere are struggling to lose weight—and to keep from putting those lost pounds right back on. For many, it’s discouraging to have their best efforts fail while those of other dieters succeed.

Researchers at the Agricultural Research Service’s Western Human Nutrition Research Center in Davis, California, are conducting studies that may provide new insights into the underlying causes of this disparity in dieting success.

Given America’s obesity epidemic, such research is timely and relevant. The U.S. Centers for Disease Control and Prevention estimates that 35 percent of U.S. adults and 18 percent of kids and adolescents age 6 through …


Enhancing Yogurt With Healthful Fiber From Oats, Mukti Singh, Sanghoon Kim, Marcia Wood Mar 2013

Enhancing Yogurt With Healthful Fiber From Oats, Mukti Singh, Sanghoon Kim, Marcia Wood

Agricultural Research Magazine

Adding about one-quarter teaspoon of a fiber-rich component of oats boosts the nutritional value of low-fat yogurt without noticeably affecting the taste or texture of this increasingly popular dairy food.

Oat fiber is of interest to foodmakers and nutritionists alike. Studies with volunteers have shown that it can lower serum cholesterol, which may help improve heart health.

Agricultural Research Service food technologist Mukti Singh, chemist Sanghoon Kim, and their colleagues experimented with adding fiber-containing oat beta-glucan to what’s known in the dairy industry as “low-fat yogurt mix.” It is made up of low-fat milk and a selection of common, safe-to-eat …

Parasitoid Infestation Changes Female Mating Preferences, Oliver M. Beckers, William E. Wagner Mar 2013

Parasitoid Infestation Changes Female Mating Preferences, Oliver M. Beckers, William E. Wagner

School of Biological Sciences: Faculty Publications

Females often adjust their mating preference to environmental and social conditions. This plasticity of preference can be adaptive for females and can have important consequences for the evolution of male traits. While predation and parasitism are widespread, their effects on female preferences have rarely been investigated. Females of the cricket Gryllus lineaticeps are parasitized by the parasitoid fly Ormia ochracea. Infestation with fly larvae substantially reduces female life span and thus reproductive opportunities of the cricket. Both female G. lineaticeps and flies orient to male song and both prefer male songs with faster chirp rates to songs with slower chirp …

Loggerhead Shrike (Lanius Ludovicianus): Species Conservation Assessment, Melissa J. Panella Mar 2013

Loggerhead Shrike (Lanius Ludovicianus): Species Conservation Assessment, Melissa J. Panella

Nebraska Game and Parks Commission: Publications

The primary goal in the development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Loggerhead Shrike (Lanius ludovicianus) as a Tier I at-risk species. Here, I provide some general management recommendations regarding Loggerhead Shrikes. However, conservation practitioners will need to use professional judgment for specific management decisions based on objectives, location, and site-specific conditions. This resource provides available knowledge of Loggerhead Shrikes that may aid in the decision-making process or in identifying research needs …


Diversification And Ecosystem Services For Conservation Agriculture: Outcomes From Pastures And Integrated Crop–Livestock Systems, Matt A. Sanderson, David Archer, John Hendrickson, Scott Kronberg, Mark Liebig, Kris Nichols, Marty Schmer, Don Tanaka, Jonathan Aguilar Mar 2013

Diversification And Ecosystem Services For Conservation Agriculture: Outcomes From Pastures And Integrated Crop–Livestock Systems, Matt A. Sanderson, David Archer, John Hendrickson, Scott Kronberg, Mark Liebig, Kris Nichols, Marty Schmer, Don Tanaka, Jonathan Aguilar

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

Conservation agricultural systems rely on three principles to enhance ecosystem services: (1) minimizing soil disturbance, (2) maximizing soil surface cover and (3) stimulating biological activity. In this paper, we explore the concept of diversity and its role in maximizing ecosystem services from managed grasslands and integrated agricultural systems (i.e., integrated crop–livestock–forage systems) at the field and farm level.We also examine trade-offs that may be involved in realizing greater ecosystem services. Previous research on livestock production systems, particularly in pastureland, has shown improvements in herbage productivity and reduced weed invasion with increased forage diversity but little response in terms of animal …

Comparison Of Recycling Outcomes In Three Types Of Recycling Collection Units, Ashley Andrews, Mary Gregoire, Heather Rasmussen, Gretchen Witowich

Department of Nutrition and Health Sciences: Faculty Publications

Commercial institutions have many factors to consider when implementing an effective recycling program. This study examined the effectiveness of three different types of recycling bins on recycling accuracy by determining the percent weight of recyclable material placed in the recycling bins, comparing the percent weight of recyclable material by type of container used, and examining whether a change in signage increased recycling accuracy. Data were collected over 6 weeks totaling 30 days from 3 different recycling bin types at a Midwest university medical center. Five bin locations for each bin type were used. Bags from these bins were collected, sorted …

Challenges In Testing Genetically Modified Crops For Potential Increases In Endogenous Allergen Expression For Safety, Rakhi Panda, H. Ariyarathna, Plaimein Amnuaycheewa, Afua O. Tetteh, S. N. Pramod, Steve Taylor, B. K. Ballmer-Weber, Richard E. Goodman

Department of Food Science and Technology: Faculty Publications

Premarket, genetically modified (GM) plants are assessed for potential risks of food allergy. The major risk would be transfer of a gene encoding an allergen or protein nearly identical to an allergen into a different food source, which can be assessed by specific serum testing. The potential that a newly expressed protein might become an allergen is evaluated based on resistance to digestion in pepsin and abundance in food fractions. If the modified plant is a common allergenic source (e.g. soybean), regulatory guidelines suggest testing for increases in the expression of endogenous allergens. Some regulators request evaluating endogenous allergens for …

Analysis Of Feeding Behavior Of Group Housed Growing–Finishing Pigs, T.M. Brown-Brandl, G.A. Rohrer, R.A. Eigenberg

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Feeding behavior and time spent eating contains valuable information that can be used for managing livestock, identifying sick animals, and determining genetic differences within a herd. Individual animal feeding behavior, in a commercial-sized pen, was recorded using radio-frequency identification (RFID) technology and a series of multiplexers. Data were collected on 960 pigs (mixed barrows, 406 and gilts, 600) over 4 grow-out periods. The animals entered the facility at 24.6 ± 5.4 kg (mean ± standard deviation) at approximately 65 days of age and exited the facility at 101.4 ± 13.8 kg (between 116 and 133 days later). Time spent at …


Effect Of Postweaning Diet On Ovarian Development And Fertility In Replacement Beef Heifers, D. R. Eborn, R. A. Cushman, S. E. Echternkamp Jan 2013

Effect Of Postweaning Diet On Ovarian Development And Fertility In Replacement Beef Heifers, D. R. Eborn, R. A. Cushman, S. E. Echternkamp

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Programs for developing replacement heifers are designed for heifers to calve at 2 yr of age and to extend their stayability in the herd and minimize feed cost. The experimental objective was to determine whether developing prepubertal heifers on less dietary energy and to a BW of 55% rather than 65% of mature BW at 14 mo of age would compromise ovarian development and reduce fertility. In a 3-yr study, 8-mo-old Angus (n = 60/yr) and composite U.S. Meat Animal Research Center II (n = 60/yr) heifers were assigned equally by age, BW, and breed to receive either a …


Inactivation Of The Pta-Acka Pathway Causes Cell Death In Staphylococcus Aureus, Marat R. Sadykov, Vinai C. Thomas, Darrell D. Marshall, Christopher J. Wenstrom, Derek E. Moormeier, Todd J. Widhelm, Austin S. Nuxoll, Robert Powers, Kenneth W. Bayles Jan 2013

Inactivation Of The Pta-Acka Pathway Causes Cell Death In Staphylococcus Aureus, Marat R. Sadykov, Vinai C. Thomas, Darrell D. Marshall, Christopher J. Wenstrom, Derek E. Moormeier, Todd J. Widhelm, Austin S. Nuxoll, Robert Powers, Kenneth W. Bayles

Robert Powers Publications

During growth under conditions of glucose and oxygen excess, Staphylococcus aureus predominantly accumulates acetate in the culture medium, suggesting that the phosphotransacetylase-acetate kinase (Pta-AckA) pathway plays a crucial role in bacterial fitness. Previous studies demonstrated that these conditions also induce the S. aureus CidR regulon involved in the control of cell death. Interestingly, the CidR regulon is comprised of only two operons, both encoding pyruvate catabolic enzymes, suggesting an intimate relationship between pyruvate metabolism and cell death. To examine this relationship, we introduced ackA and pta mutations in S. aureus and tested their effects on bacterial growth, carbon and energy …

Chromogenic Agar Medium For Detection And Isolation Of Escherichia Coli Serogroups O26, O45, O103, O111, O121, And O145 From Fresh Beef And Cattle Feces, Norasak Kalchayanand, Terrance M. Arthur, Joseph M. Bosilevac, James E. Wells, Tommy L. Wheeler

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Non-O157 Shiga toxin–producing Escherichia coli (STEC) strains are clinically important foodborne pathogens. Unlike E. coli O157:H7, these foodborne pathogens have no unique biochemical characteristics to readily distinguish them from other E. coli strains growing on plating media. In this study, a chromogenic agar medium was developed in order to differentiate among non-O157 STEC strains of serogroups O26, O45, O103, O111, O121, and O145 on a single agar medium. The ability of this chromogenic agar medium to select and distinguish among these pathogens is based on a combination of utilization of carbohydrates, β-galactosidase activity, and resistance to selective agents. The agar …

Isolation And Characterization Of The Grain Mold Fungi Cochliobolus And Alternaria Spp. From Sorghum Using Semiselective Media And Dna Sequence Analyses, Deanna L. Funnell-Harris, Louis K. Prom, Jeffrey F. Pedersen

Department of Plant Pathology: Faculty Publications

Mold diseases, caused by fungal complexes including Alternaria, Cochliobolus, and Fusarium species, limit sorghum grain production. Media were tested by plating Fusarium thapsinum, Alternaria sp., and Curvularia lunata, individually and competitively. Dichloran chloramphenicol rose bengal (DRBC) and modified V8 juice (ModV8) agars, found to be useful, were compared with commonly used agar media, dichloran chloramphenicol peptone (DCPA) and pentachloronitrobenzene (PCNB). Radial growth, starting with mycelia or single-conidia and hyphal tips, demonstrated an effect of media. For isolation of grain fungi, DRBC and ModV8 were similar or superior to DCPA and PCNB. When seedlings were inoculated with conidia of C. lunata, …


The Real Dirt On Biosolids As Soil Amendments, Eton Codling, Ann Perry Jan 2013

The Real Dirt On Biosolids As Soil Amendments, Eton Codling, Ann Perry

Agricultural Research Magazine

The U.S. Environmental Protection Agency (EPA) estimates that more than 60 percent of dry biosolids—treated wastewater solids that can be recycled or stored—are applied to land, composted, or used to cover landfills. The biosolids have been processed to kill pathogens, and EPA strictly regulates biosolid use to ensure the materials don’t harm the environment, human health, or animal health.

Farmers who follow pre- and post-application management regulations can obtain permits to use biosolids for amending fields where food and feed crops are grown. Now, research by an Agricultural Research Service scientist is helping to clarify the long-term effects that biosolid …


With Hot Air Treatment, Bacteria Fly The Coop, Rosalie Marion Bliss, Mark E. Berrang Jan 2013

With Hot Air Treatment, Bacteria Fly The Coop, Rosalie Marion Bliss, Mark E. Berrang

Agricultural Research Magazine

While being transported in hauling coops on trucks, poultry that have been colonized with bacteria such as Campylobacter can contaminate, through fecal shedding, pathogen-free poultry. Those pathogens can also be passed on to the next group of birds during the next trip, and so forth, unless the cycle is broken.

That’s where Agricultural Research Service microbiologists Mark Berrang and Richard Meinersmann and colleague Charles Hofacre at the University of Georgia in Athens come in. The team has reported a treatment that reduces poultry cross-contamination from transport-cage flooring.

Campylobacter are foodborne pathogens that can be present in raw or undercooked poultry. …


Going Beyond The Barnyard To Stop Stable Flies, David B. Taylor, J.J. Zhu, Sandra Avant Jan 2013

Going Beyond The Barnyard To Stop Stable Flies, David B. Taylor, J.J. Zhu, Sandra Avant

Agricultural Research Magazine

Livestock producers may not be able to see the difference between stable flies and other flies at a distance, but they can definitely see the stable flies’ effect on their cattle as the animals stop grazing and bunch together to minimize the number of bites they’re getting.

Stable flies are among the most important arthropod pests of cattle in the United States. Their painful bites can reduce milk production in dairy cows, decrease weight gain in beef cattle, and reduce feed efficiency.

Generally, insecticide sprays are used to help keep stable flies off animals, especially their legs, where the flies …
