The Localism Movement: Shared And Emergent Values, Nancy B. Kurland, Sara Jane Mccaffrey, Douglas H. Hill

Journal of Environmental Sustainability

Localism, a movement to encourage consumers and businesses to purchase from locally owned, independent businesses rather than national corporations, has grown rapidly in the past decade. With several national, federated organizations and popular “buy local” campaigns, the localism movement has the potential to affect buying patterns, marketing, and distribution in American business. Yet localism remains understudied by researchers. This article, based on data from 38 interviews with localism leaders, identifies four of the movement’s priorities: independent ownership, local buying, local sourcing, and pragmatic partnering. In addition, we analyze the movement’s emerging values, including responsibility to workers and to the natural …

Sustainable Rural Entrepreneurship: A Case In Hungary, Szilvia Luda

Journal of Environmental Sustainability

Hungary, along with the other member states of the EU, is making efforts to diminish the social and economic gap between the different regions of the country. EU cohesion funds are designed to serve this goal. However, the utilization of these resources is not efficient enough. The problem is exacerbated by how the disadvantaged regions are supported. Support is provided on the basis of various indicators, such as per capita GDP, life expectancy, residents’ educational status, etc. Omitted from this indicator set is reference to the environment or other structural characteristics of the region (such as proximity to big cities; …

2012 Kentucky Equine Survey, College Of Agriculture, Food And Environment, University Of Kentucky, Kentucky Agricultural Development Fund, Kentucky Horse Council, Ag Equine Programs, University Of Kentucky

Kentucky Equine Survey

The last thorough equine inventory in Kentucky was undertaken in 1977, leaving the state’s equine industry with 35 years of changes, growth and con­traction that were neither measured nor analyzed.

In response to these needs, in 2011, the University of Kentucky and the Kentucky Horse Council, with support by industry organizations spearheaded by the Kentucky Quarter Horse Association, the Kentucky Thoroughbred Farm Managers’ Club and Kentucky Thoroughbred Association/Kentucky Thoroughbred Owners and Breeders, and initial support from the University of Louisville, succeeded in securing fund­ing for a large-scale, comprehensive equine survey upon which future industry plans could be built. This was …

Amino Acid Supply And Utilization With Emphasis On Lysine And Impacts On Lactation Responses Of Dairy Cows Fed Rations Containing Distillers’ Dried Grains With Solubles, Henry Paz

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

Inclusion of feed coproducts in dairy diets is a common strategy used to reduce the cost of producing milk. The corn ethanol industry produces a coproduct namely distillers dried grains with solubles (DDGS) which could be of high value to the dairy industry because of its high concentration of protein and energy. Under the feeding regimes in the U.S., Lys and Met are recognized as the two most limiting amino acids (AA) for milk protein synthesis. Similar to corn, DDGS is limiting in Lys but not Met. Thus, high inclusions of DDGS have not been favored in the field as …

Assessing The Bioconfinement Potential Of A Nicotiana Hybrid Platform For Use In Plant Molecular Farming Applications, J. Hollis Rice, Richard E. Mundell, Reginald J. Millwood, Orlando D. Chambers, C. Neal Stewart, H. Maelor Davies

Kentucky Tobacco Research and Development Center Faculty Publications

BACKGROUND: The introduction of pharmaceutical traits in tobacco for commercial production could benefit from the utilization of a transgene bioconfinement system. It has been observed that interspecific F1Nicotiana hybrids (Nicotiana tabacum × Nicotiana glauca) are sterile and thus proposed that hybrids could be suitable bioconfined hosts for biomanufacturing. We genetically tagged hybrids with green fluorescent protein (GFP), which was used as a visual marker to enable gene flow tracking and quantification for field and greenhouse studies. GFP was used as a useful proxy for pharmaceutical transgenes.

RESULTS: Analysis of DNA content revealed significant genomic downsizing of the hybrid relative to …

Prescription For Curing Citrus Greening, Dennis O’Brien, Yongping Duan

Agricultural Research Magazine

Huanglongbing (HLB), or citrus greening, is the most serious threat to the Florida citrus industry in its history and is costing millions of dollars each year. Working with the Florida Department of Agriculture and Consumer Services (FDACS), Yongping Duan and his Agricultural Research Service colleagues in Fort Pierce, Florida, have found a formula for curbing HLB, offering the industry a glimmer of hope.

Duan has published details of work showing that heating potted citrus seedlings in greenhouses kills off the HLB bacterium and can rid the seedlings of citrus greening symptoms. Monitoring efforts show that the benefit can last for …

Early Weaning: A Good Bet For Beef Producers In Drought-Stricken Areas, R.C. Waterman, Sandra Avant

Agricultural Research Magazine

At the beginning of 2013, cattle-ranchers in the Northern Plains were among U.S. agricultural producers still feeling the lingering effects of the sweltering 2012 drought, the worst in half a century.

Beef cow numbers were at the lowest in 50 years as U.S. beef producers—severely affected by extended drought—tried to recover from some of the driest months on record.

Across the Northern and Southern Plains, beef producers hit the hardest by drought are threatened by limited forage resources for cows, which restricts calf growth, resulting in lighter calf weaning weights. In addition, drought can decrease cow body weight and condition …

Scientific Works Of Art Reveal A Hidden World, Gary Bauchan, Jan Suszkiw

Agricultural Research Magazine

It has been said that a picture is worth a thousand words, and at the Agricultural Research Service’s Electron and Confocal Microscopy Unit (ECMU) in Beltsville, Maryland, this adage couldn’t be more true. Led by unit director Gary Bauchan, the ECMU is tasked with producing highresolution images that provide a window to the extraordinary world of the unseen.

“We have observed viruses, bacteria, fungi, nematodes, insects, mites, and parasites that threaten global food security, and we’ve contributed to the discovery of how pathogens spread by helping elucidate their relationship to the environment, hosts, and vectors,” says Bauchan. “We’ve also described …

Novel Ways To Combat Plant Pathogens, Deborah Fravel, Gail C. Wisler

Agricultural Research Magazine

Plant diseases must be managed to successfully and reliably produce crops to meet humanity’s growing food, fiber, feed, and fuel needs. Plant disease management relies on many different types of tools—from disease-resistant plant varieties and pesticides to cultural and biological strategies. Agricultural Research Service scientists are seeking new methods of managing plant diseases, more efficient means of using older methods, and combinations of these methods. Two of the oldest ways of reducing plant diseases are crop rotation and organic amendments to soil.

In Orono, Maine, for example, ARS scientists are evaluating a holistic approach to suppressing soilborne pathogens of potato, …

Possible Links Between Soil Microbial Communities And Stroke Risk, Ann Perry

Agricultural Research Magazine

“A big part of our Agricultural Research Service culture is cross-talking with outside researchers,” says ARS soil and water scientist Patrick Hunt. “Partnerships are what we do.”

So one day in 2011, Hunt called Medical University of South Carolina professor Daniel Lackland to discuss a paper Lackland had published about stroke risk in the state. South Carolina is part of the U.S. “Stroke Belt,” where residents have a significantly higher incidence of stroke than the rest of the U.S. population. South Carolina counties with the highest rates of stroke—between 89 and 115 cases per 100,000 residents—are found within the Southern …

Fungal Foam Tested Against Avocado Threat, Jan Suszkiw

Agricultural Research Magazine

Avocados aren’t just nutritional powerhouses; they’re also the chief ingredient in such party favorites as guacamole dip.

More than 99 percent of the nation’s $322 million avocado crop is grown in south Florida and southern California (less than 1 percent is produced in Hawaii), which makes recent infestations of groves there by invasive, wood-boring ambrosia beetles so alarming. A host of counter strategies are in the works, including a biobased foam originally developed by Agricultural Research Service scientists for use against Formosan subterranean termites.

In Miami-Dade County, Florida, avocado growers are contending with Xyleborus glabratus, the redbay ambrosia beetle. …

Fire Ant Venom Compounds May Be Useful As A Fungicide, Jan Suszkiw, Jian Chen, Xixuan Jin

Agricultural Research Magazine

Red imported fire ants are named for the firelike burn of their sting. Now, the same venom that packs such a painful wallop may actually do some good for a change.

Studies by scientists at the Agricultural Research Service’s Biological Control of Pests Research Unit in Stoneville, Mississippi, have shown that certain alkaloid compounds in the venom—namely, piperideines and piperidines—can hinder growth of Pythium ultimum, a top crop pathogen worldwide.

Chemical controls, delayed plantings, and crop rotation are among methods now used against P. ultimum, which causes damping-off diseases that decay the seed or seedlings of vegetable, horticultural, …

Ars Validates Soil Moisture Data Collected Via Satellite, Ann Perry

Agricultural Research Magazine

The European Space Agency’s Soil Moisture and Ocean Salinity (SMOS) mission includes the latest advance in using Earth-orbiting satellites for estimating soil moisture across the globe. The SMOS satellite was launched in 2009 and was designed to estimate soil moisture levels to within 4 percent, which is like measuring a teaspoon of water in a handful of dry soil.

To capture this data, SMOS uses a new sensor technology that is the first passive L-band system—measuring microwave radiation emitted around the frequency of 1.4 gigahertz—in routine operation. But the accuracy of the information collected by this new technology still needs …

New Strategies To Thwart Pecan Scab, Sharon Durham

Agricultural Research Magazine

Pecans are great for eating out of the shell or in a myriad of recipes. But abundant pickings of high-quality nuts are only possible if the tree escapes the devastating disease called “pecan scab.” Caused by the fungus Fusicladium effusum, it is the most destructive disease of pecan in the southeastern United States. When scab is severe, most often when rainfall is above average, nut size is reduced, and total crop loss might occur.

Scientists at the Southeastern Fruit and Tree Nut Research Laboratory in Byron, Georgia, are working to help pecan growers mitigate the effect of pecan scab. …

Screening Fresh Oranges With Uv Study Pinpoints New Value Of Detection Tactic, David M. Obenland, Joseph L. Smilanick, Marcia Wood

Agricultural Research Magazine

Fresh, deliciously sweet navel oranges, on display at your local supermarket, may have been quickly inspected with ultraviolet (UV) light when they were still at the packinghouse. Usually, the purpose of this special sorting and screening is to see if circular spots—which glow a bright, fluorescent yellow and may be about the size of a quarter or larger—show up on the fruit’s peel.

More often than not, these spots, which scientists refer to as “lesions,” are telltale indicators of the presence of microbes that cause decay, namely Penicillium italicum, responsible for blue mold, or P. digitatum, the culprit …

Frequency And Distribution Of Extended Diapause In Nebraska Populations Of Diabrotica Barberi (Coleoptera: Chrysomelidae), Ryan W. Geisert, Lance J. Meinke

Department of Entomology: Faculty Publications

The frequency of extended diapause in populations of the northern corn rootworm, Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae), was measured in eastern Nebraska. Adult collections were made during late summer in 2008 and 2009 from eight sites each year (seven sites were consistent over years). Eggs were obtained from 12 to 20 females per site and were held on moist soil under appropriate temperature profiles to facilitate egg survival, diapause development, and diapause termination. Percentage egg hatch was recorded after the first and second year for the 2008 and 2009 collections. Additional extended diapause expression was estimated for the …

Characteristics Of White-Tailed Deer Visits To Cattle Farms: Implications For Disease Transmission At The Wildlife-Livestock Interface, Are R. Berentsen, Ryan S. Miller, Regina Misiewicz, Jennifer L. Malmberg, Mike R. Dunbar

Zoonotics and Wildlife Disease: Publications

Bovine tuberculosis (bTB) is endemic in free-ranging white-tailed deer (Odocoileus virginianus) in MI, USA. Currently, the rates of farm visitation by deer and co-use of forage resources by cattle and deer are poorly understood. To evaluate the extent deer and livestock may share forage resources, we investigated farm, yard, and cattle-use area visitation by white-tailed deer and compared visitation with common livestock management practices. We fitted 25 female white-tailed deer near the bTB-infected zone in Michigan’s Lower Peninsula with global positioning system collars. Livestock management practices associated with farm visitation included presence of confined feeding pastures, number of …

Ammonia And Nitrous Oxide Loss From Sprinkler Applied Beef Feedlot Effluent, Blythe P. Mcafee

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

A range of flux chambers are available and have been used to measure fluxes of atmospheric gases, including NH₃, with the addition of acid traps. Previous studies show acid traps can be very effective but there is a need to understand how chambers affect acid trap efficiency so measurements can be adjusted for more accurate results. In this lab study, chamber tightness, pump flow variation, and NH₃ trapping efficiency of a flux chamber system were examined. Chamber leakage varied with time from 1-7%. Pumping rate between pumps was significantly different and when included in the closed chamber …

A Roadmap To Mindful Consumption Through Informative Labeling Practices: The Effects Of Sustainability Disclosure Formats On Consumer Product Evaluations, Yoon-Na Cho

Graduate Theses and Dissertations

Despite the interest of consumers in sustainable and environmentally friendly products, only a limited number of studies have focused on sustainability level disclosures for consumer packaged goods. The general overarching purpose of this dissertation is to extend the internal reference point and information processing literatures to better understand how consumers will process sustainability disclosures. Applying the theoretical lens of assimilation bias in conjunction with self-enhancement offers an important extension to prior work. Across two retail lab studies and four online experiments, I demonstrate that the perceived sustainability utility (i.e., the difference between a specific brand's level of sustainability and category-level …
