Crisis Communication Needs Assessment: A Delphi Study To Enhance Instruction For Agricultural Communicators And Other Stakeholders, Allyson Ceary Mcguire
Crisis Communication Needs Assessment: A Delphi Study To Enhance Instruction For Agricultural Communicators And Other Stakeholders, Allyson Ceary Mcguire
Graduate Theses and Dissertations
Agricultural communicators and industry stakeholders need to be able to develop, prepare and implement crisis communication plans to help assure the sustainability of the agriculture industry should a crisis event occur. A thorough exploration of possible options and needs for training crisis communicators is a needed study in the agriculture industry. Students learning to prepare for managing crises in real life situations are rarely taught in a hands-on, experiential manner. Students can read and analyze case studies pertaining to crises, but without having an actual crisis; little means exist for preparing students for real world situations. There is a need …
Analyzing Spring Freeze Impacts On Deciduous Forest Productivity Using Modis Satellite Imagery, Karl Lintvedt
Analyzing Spring Freeze Impacts On Deciduous Forest Productivity Using Modis Satellite Imagery, Karl Lintvedt
Graduate Theses and Dissertations
The impacts of an April 2007 spring freeze event on the productivity of deciduous broadleaf forest were analyzed using geographic information system (GIS) tools. Forest productivity was modeled using the Enhanced Vegetation Index (EVI), as recorded by the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor. Measures of spatial autocorrelation were used to quantify the degree of spatial congruence between a map depicting the severity of the freeze event, and maps modeling forest productivity throughout the year. The results show a geographic correlation between the unseasonably low minimum temperatures sustained during the freeze and the unusually low forest productivity that followed. …

Impact Of Agricultural Profitability, Productivity And Interest Rate On Farmland Value For Selected U.S. And Slovak States, Maria Majerhoferova
Graduate Theses and Dissertations
This thesis examines agricultural factors which may have impact on agricultural land values. Based on theory, three primary factors are considered to have an impact on land value: agricultural productivity, agricultural profitability and interest rate. The study is of two countries: the US, where data are from 16 states and Slovakia with 6 states. The ten-year period from 2000 until 2009 is used in the analysis. A capitalization model is used to estimate the relationship between agricultural productivity, profitability and interest rate and land value. Three types of agricultural land are used: cropland and its value in relationship with crops, …

Marketing Margins Of Strawberries 2006-2010 Shipping Point-Terminal-Retail Price, Matej Mikle Barat
Graduate Theses and Dissertations
This thesis examines vertical price relationships for fresh strawberries. Specifically, the focus is on three stages of the vertical chain. The first stage is the shipping point. Shipping points represent major strawberry production regions and are the closest price point to the farm. The second stage is the terminal market. Terminal markets are wholesale markets in major US cities. The third stage is the retail level. Retail level prices are measured as average supermarket prices in the same cities for which terminal market prices are available. Using weekly data, markup equations are estimated from upstream to downstream levels of the …

Genetic manipulation of crop plants, through breeding or transgenic approaches, for enhanced tolerance to abiotic stress holds great promise for improving yields and promoting new methods for sustainable agriculture. This study examines the potential role that genes of the soybean, Glycine max L., encoding elongation factor-1 alpha (EF-1α) and glyoxalase I (GlxI) might play in response to salt stress. Previous reports have suggested a possible function for both GlxI and EF-1α in conferring enhanced salt tolerance in other plant species. In addition to other possible mechanisms, salt tolerance in soybeans can be regulated by plant uptake and transport of chloride …

Storage Effects Of Gel Encapsulation On Stability Of Chokeberry Monomeric Anthocyanins, Procyanidins, Color Density, And Percent Polymeric Color, Mary Kordsmeier, Luke Howard
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Chokeberries (Aronia melanocarpa) are an antioxidant-rich plant product due to their high content of polyphenols, especially anthocyanins and procyanidins. These polyphenols have been shown to provide protection against coronary heart disease, stroke, and lung cancer, as well as against oxidative stress, the main cause behind chronic diseases promoted by free radicals. The objective of this study was to determine the storage effects of gelatin encapsulation on monomeric anthocyanins, procyanidins, color density, and percent polymeric color of three gummy candies of different strengths formulated with a base of 25.4% chokeberry concentrate, 47.6% sucrose, 1.3% Splenda, and 0.025% potassium sorbate. The gum …

Comparison Of Growing Media For Container Grown Plants, Paul Harris, David Longer, Derrick Oosterhuis, Dimitra Loka
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Greenhouse and growth chamber experiments are conducted worldwide in efforts to produce solutions that would increase yields of agronomic crops. However, the results of those experiments vary due to the many growth media being used. An experiment was conducted in the fall of 2010 to identify a broadly acceptable growth media that would produce uniform stands and optimum results in greenhouse and growth chamber settings. A total of six growth media were tested on cotton (Gossypium hirsutum) at the Arkansas Agricutural Research and Extension Center’s Altheimer Lab in Fayetteville. The plants grown in each medium were harvested six weeks after …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Objectives of this project were to evaluate polymorphisms in upstream elements of the lactate dehydrogenase B (LDHB) gene in crossbred dairy heifers (n = 27) and their effects on immune function and heifer growth when grazing endophyte-infected tall fescue. Two cultivars of tall fescue were utilized: Kentucky 31 (KY31), a wild-type endophyte-infected tall fescue, and HiMag 4 (HiMag), a domesticated non-toxic endophyte-infected tall fescue. Crossbred dairy heifers (Holstein × Jersey) were stratified by weight and randomly allotted to forage. The LDHB gene codes for one subunit of lactate dehydrogenase (LDH), an enzyme that catalyzes pyruvate to lactate and back to …

A Novel Gene Silencing Vector For Plant Genomics And Biotechnology, Dustin Hoover, Scott Nicholson, Vibha Srivastava
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Gene silencing is a process of suppressing activity of specific genes by producing “interfering” RNA encoded by foreign genes. This process serves as the principle of genetic modification in plants and animals, which is an important tool in genomics and biotechnology, allowing scientists to manipulate organisms to better meet human demands. New approaches of gene silencing may enable improvements on current practices of genetic modification, and broaden the application and impact of gene silencing in biotechnology. Recently, a novel vector design consisting of the transcription of short gene fragments lacking transcription termination signals was demonstrated to be effective in partial …
The Efficacy Of Thermal Imaging Technology For Documenting American Woodcock On Pine Stands, A. Long, A. Locher
The Efficacy Of Thermal Imaging Technology For Documenting American Woodcock On Pine Stands, A. Long, A. Locher
Journal of the Arkansas Academy of Science
Thermal imaging technology provides a useful tool to understand nocturnal activity of wildlife. We used thermal imaging to document American woodcock use of pine stands in Arkansas. A thermal imaging camera was used along logging roads on sampling dates ranging from December 2009 – February 2010 and in February 2011. We located 4 woodcock in 2010 in 20.27 hours of sampling within all stand types. For 11.55 h we only sampled pine seedling/clearcut stands due to vegetation structure inhibiting our ability to identify woodcock with the camera. In 2011 we found 2 woodcock in 7.42 hours of sampling on pine …
Sequence Analysis Of The Angiotensin Ii Type 1 Receptor (Agtr1) Gene For Mutations Contributing To Pulmonary Hypertension In The Chicken (Gallus Gallus), John Russell Burks
Sequence Analysis Of The Angiotensin Ii Type 1 Receptor (Agtr1) Gene For Mutations Contributing To Pulmonary Hypertension In The Chicken (Gallus Gallus), John Russell Burks
Inquiry: The University of Arkansas Undergraduate Research Journal
Our multidisciplinary group at the University of Arkansas has been investigating the suitability of the chicken as a medical model for pulmonary arterial hypertension (PAH) in humans. There are several forms of PAH in humans arising from elevated pulmonary arterial pressure and pulmonary vascular resistance. Spontaneous cases of PAH are known as idiopathic PAH (IPAH), where the exact physiological causes are not known. IPAH patients that do not respond to standard treatments have a prognosis of only a few years. Currently, there is no acceptable animal model for IPAH. As part of our effort to pursue the chicken as model …
