    With the Waxman-Markey Bill passing the House and the administration’s push to reduce carbon emissions, the likelihood of the implementation of some form of a carbon emissions policy is increasing. This study estimates the greenhouse gas (GHG) emissions of the six largest row crops produced in Arkansas using 57 different production practices predominantly used and documented by the University of Arkansas Cooperative Extension Service. From these GHG emission estimates, a baseline state “carbon footprint†was estimated and a hypothetical GHG emissions reduction of 5, 10, and 20 percent was levied on Arkansas agriculture using a cap-and-trade method. Using current production technology and traditional land use choices, results show that the trading of carbon-emitting permits to reduce statewide GHG emissions by 5 percent from the baseline would enhance GHG emissions efficiency measured as net crop farm income generated per unit of carbon emissions created. The 5 percent reduction in GHG emissions does cause marginal reductions in acres farmed and has marginal income ramifications. Beyond the 5 percent reduction target, gains in GHG emissions efficiency decline but remain positive in most counties through the 10 percent GHG reduction target. However, with a 10 percent GHG reduction, acreage and income reductions more than double compared to the 5 percent level. When GHG emissions are reduced by 20 percent from the baseline, the result is a major cropping pattern shift coupled with significant reductions in traditional row crop acreage, income, and GHG emissions efficiency.greenhouse gas emissions, carbon equivalents, sustainability, cap and trade, Environmental Economics and Policy, Resource /Energy Economics and Policy,

    With the Waxman-Markey Bill passing the House and the Obama administration’s push to reduce carbon emissions, the likelihood of the implementation of some form of a carbon policy is increasing. This study estimates the greenhouse gas (GHG) emissions of the six largest crops produced in Arkansas using 63 different production practices as documented by University of Arkansas Cooperative Extension Service. From these GHG estimates a baseline state “carbon footprint” was estimated and a hypothetical cap-and-trade carbon reduction of 5, 10, and 20% was levied on Arkansas agriculture. Results show that while a modest reduction in GHG emissions (5%) would only affect crop allocations amongst certain crops while marginally reducing state net returns, a 20% reduction would cause major cropping pattern shifts with some traditional row crops nearly disappearing.Cap-and-Trade, carbon, sustainability, Agricultural and Food Policy, Environmental Economics and Policy, Q28, Q52, Q54, Q56,

    Neutrophil cell surface receptors and their intracellular signal transduction pathways

    AbstractNeutrophils play a critical role in the host defense against bacterial and fungal infections, but their inappropriate activation also contributes to tissue damage during autoimmune and inflammatory diseases. Neutrophils express a large number of cell surface receptors for the recognition of pathogen invasion and the inflammatory environment. Those include G-protein-coupled chemokine and chemoattractant receptors, Fc-receptors, adhesion receptors such as selectins/selectin ligands and integrins, various cytokine receptors, as well as innate immune receptors such as Toll-like receptors and C-type lectins. The various cell surface receptors trigger very diverse signal transduction pathways including activation of heterotrimeric and monomeric G-proteins, receptor-induced and store-operated Ca2+ signals, protein and lipid kinases, adapter proteins and cytoskeletal rearrangement. Here we provide an overview of the receptors involved in neutrophil activation and the intracellular signal transduction processes they trigger. This knowledge is crucial for understanding how neutrophils participate in antimicrobial host defense and inflammatory tissue damage and may also point to possible future targets of the pharmacological therapy of neutrophil-mediated autoimmune or inflammatory diseases

    Valuation of Temp-Time's Fresh-Check® Indicator on Perishable Food Products in Belgium

    Consumers are becoming acutely attentive to the factors that influence food safety and food wholesomeness. The food industry is well regulated, yet there is still illness that results from contaminated fresh food products. Recent food contamination outbreaks and concerns with how food is grown have created an almost hypersensitive food consumer. The TempTime Corporation is a leading international manufacturer in time-temperature sensitive indicators for fresh food products. This company's aim is to provide consumers with more information about exactly what happens to their product from the initial packaging of the product to the time of consumption. Their product, called Fresh-Check®, is about the size of a postage stamp, and is affixed to the outer packaging of fresh food products. It is used in conjunction with the use-by-date to ensure a safe and fresh product. This paper focuses on consumer perceptions of the Fresh-Check indicator in Belgium. We employed the contingent valuation survey method to capture Belgian consumer's overall perception, willingness to pay, preference, and acceptance for Temp-Time's Fresh-Check® indicator on fresh food products
