| The objective of this research is to identify factors that influence both the decision (yes or no) and level of flood insurance among coastal homeowners in the southeast U.S. Recently flood damage has dramatically increased (Flood), and Crossett et al. (2004) report that coastal populations are growing. And in spite of rising costs of living in coastal areas, people are willing to pay more for access to ocean views and other natural amenities associated with coastal living (Bin and Kruse, 2006). Although the federal government provides flood insurance programs and encourages at-risk residents to insure their property from flood, rates of uptake remain low (Burby, 2001; Kunreuther, 2006; Landry and Jahan-Parvar, 2009). The National Flood Insurance... |

| The paper addresses "food safety" and 'food quality' from the position of commodity and food science rather than economy. The various descriptions of both terms in literature are reviewed in connection with customer/supplier ability to evaluate food safety and quality by examination of various characteristics. Food safety has been described as opposite to food risk. Differences in perception of food risk by customer, producer/supplier and official agencies are discussed in this paper. The objective safety (and quality) of food can be evaluated using three categories of food risk (biological, chemical and physical) measured on a seven step intensity scale by producers and official agencies but not by customers. This leads to formulating food safety policy... |

| Forward contracting of inputs in production agriculture is becoming increasingly important as more farmers attempt to manage risk. Using a logit model and farm-level data, this analysis estimates the effect of factors on the probability of a producer using forward input contracting. Results suggest that use of contracting in selling of crops and livestock, technology, farm size, geographic location, participation in government commodity programs, and use of extension services are important factors affecting the choice to forward contract inputs. |

| This paper estimates optimal hedging ratios for a Finnish spring wheat producer under price and yield risk. The forward contract available for hedging fixes the price and quantity at the time of sowing for a delivery at harvest. Autoregressive models are used to obtain point forecasts for the conditional mean price and price volatility at harvest. Expected yield and yield volatility are estimated from the field experiment data. A range of coefficients of absolute risk aversion are used in the computations. The results suggest that yield volatility is large and it dominates the price volatility in the optimal hedging decisions of the Finnish wheat producers. Nevertheless, a potential for large negative correlation between the price and the yield decreases... |

| Governance of infectious disease risks requires understanding of often indeterminate interactions between diverse, complex, open, and dynamic human and natural systems. In the face of these challenges, worldwide policy making affords disproportionate status to “ science-based” risk-assessment methods. These reduce multiple, complex dimensions to simple quantitative parameters of “outcomes” and “probabilities,” and then re-aggregate across diverse metrics, contexts, and perspectives to yield a single ostensibly definitive picture of risk. In contrast, more precautionary or participatory approaches are routinely portrayed as less rigorous, complete, or robust. Yet, although conventional... |

| The aim of this study was to perform an updated meta-analysis to quantitatively investigate the association between G20210A polymorphism of Prothrombin gene and the risk of retinal vein occlusion (RVO), based on the available publications with inconsistent results. We utilized the Stata software to perform the heterogeneity test, association test, Begg's and Egger's tests, and sensitivity analysis. We searched three on-line databases (PubMed, Embase, and WOS) and obtained a total of 422 articles. Based on our selection criteria, 24 case-control studies were finally enrolled in this overall meta-analysis; a subgroup analysis by the factors ethnicity, control source, and RVO type was done. Through the association test of overall meta-analysis, we did not... |

| The paper discusses the linkages between the "globalization" of agricultural markets over recent decades and the decisions being made by individual farmers and ranchers in the United States. It is noted that technological advances lead to globalization of agricultural commodity markets and profit pressures. The continuing profit squeeze in agricultural production is having a significant effect on the cropping choices of America's farmers. When possible, acreage is being shifted out of low-revenue-generating crops and into higher-revenue-generating crops. This shift makes crop portfolios more risky over time, thus encouraging farmers to consider diversifying out of agriculture. |

| A farmer's decision to contract or produce independently depends on the distribution of income under both arrangements, and on attributes associated with both business arrangements. Risk-averse farmers should be willing to pay a risk premium for the reduction in price risk provided by a contract. Farmers with a preference for "autonomy" should be willing to pay a premium for certain attributes associated with independent production, such as the right to make management decisions and own the commodity they produce. The benefits to growers from contracting (such as risk reduction) may be over-estimated if the non-pecuniary benefits enjoyed by independent producers are not accounted for. This study uses national survey data to estimate the risk premium, the... |

| Many policy issues, as well as policy funding and management choices, have elements of risk and uncertainty. This means that choice experiments, such as those used in choice modelling (CM), may need to frame trade-offs so that risk and uncertainty are included. This research aims to explore some methodological approaches to identify and treat uncertainty in CM experiments. A review of theoretical models, as well as a case study application in the CM technique reported by Roberts et al. (2008), suggests that including uncertainty information in the choice sets should influence responses significantly. However, key challenges remain to define and describe the elements of risk and uncertainty that are to be included in a choice experiment, to communicate the... |

| Potential poverty traps among the rural poor suggest a need to reduce poor farmers' vulnerability by stabilizing crop yields and limiting yield losses. Advances in agricultural biotechnology enable breeders to address this need more directly than ever before with crops that reduce production risk by tolerating climate fluctuation or resisting biotic stresses. Will poor farmers who could benefit most from less vulnerability choose to purchase such risk-reducing seeds? I use data from a household survey and experiment involving farmers in India to infer their valuation of changes in the mean, variance, and skewness of yield distributions. I conclude that these farmers value increases in expected yield in the yield distribution but seem indifferent about... |

| Emerging diseases pose a recurrent threat to bivalve aquaculture. Recently, massive mortality events in the Pacific oyster Crassostrea gigas associated with the detection of a microvariant of the ostreid herpesvirus 1 (OsHV-1 µVar) have been reported in Europe, Australia and New Zealand. Although the spread of disease is often viewed as a governance failure, we suggest that the development of protective measures for bivalve farming is presently held back by the lack of key scientific knowledge. In this paper, we explore the case for an integrated approach to study the management of bivalve disease, using OsHV-1 as a case study. Reconsidering the key issues by incorporating multidisciplinary science could provide a holistic under-standing of OsHV-1 and... |
