HEDGING AND PRODUCTION DECISIONS UNDER A LINEAR MEAN-VARIANCE PREFERENCE FUNCTION

A firm model of production and hedging decisions is developed using a mean-variance preference function. Comparative static analysis of the model generates a number of testable hypotheses. For example, the influence of price risk, production risk and hedging cost on the optimal level of production and hedging is analyzed in the framework.Farm Management,

National Rugby League athletes and tendon tap reflex assessment: A matched cohort clinical study

BACKGROUND: Limited research suggests elite athletes may differ from non-athletes in clinical tendon tap reflex responses. METHODS: In this matched cohort study, 25 elite rugby league athletes were compared with 29 non-athletes to examine differences in tendon reflex responses. Relationships between reflex responses and lengths of players’ careers were also examined. Biceps, triceps, patellar and Achilles tendon reflexes were clinically assessed. RESULTS: Right and left reflexes were well correlated for each tendon (r(S) = 0.7–0.9). The elite rugby league athletes exhibited significantly weaker reflex responses than non-athletes in all four tendons (p < 0.005). Biceps reflexes demonstrated the largest difference and Achilles reflexes the smallest difference. Moderate negative correlations (r(S) = −0.3–0.6) were observed between reflex responses and lengths of players’ careers. CONCLUSIONS: Future research is required to further elucidate mechanisms resulting in the observed differences in tendon reflexes and to ensure clinical tendon tap examinations and findings can be interpreted appropriately in this athletic population

AN ANALYSIS OF THE ROLE OF FUTURES PRICES, CASH PRICES AND GOVERNMENT PROGRAMS IN ACREAGE RESPONSE

An integrated investigation of futures price, cash price, and government programs is presented in the context of an econometric model of acreage supply response for U.S. corn and soybeans. The analysis refines the role of different sources of price information in the farmers' acreage decision. It is found that the government corn support price program plays a major role in corn and soybean production decisions. Also, the results indicate that futures prices are not good proxies for expected future cash prices in the presence of government programs. This raises questions about the information efficiency of futures prices when government intervenes in the market place.Crop Production/Industries,

A Killing tensor for higher dimensional Kerr-AdS black holes with NUT charge

In this paper, we study the recently discovered family of higher dimensional Kerr-AdS black holes with an extra NUT-like parameter. We show that the inverse metric is additively separable after multiplication by a simple function. This allows us to separate the Hamilton-Jacobi equation, showing that geodesic motion is integrable on this background. The separation of the Hamilton-Jacobi equation is intimately linked to the existence of an irreducible Killing tensor, which provides an extra constant of motion. We also demonstrate that the Klein-Gordon equation for this background is separable.Comment: LaTeX, 14 pages. v2: Typo corrected and equation added. v3: Reference added, introduction expanded, published versio
