| An econometric model was used to estimate the supply response of corn, cotton, and soybeans in the Southeast United States. The analysis includes state-level data from 1991-2005 for Alabama, Florida, Georgia, North Carolina, South Carolina, Tennessee, and Virginia, taking into account the effect of wealth, revenue risk, and farm program provisions. Estimated elasticities were low and many parameters were not statistically significant. |

| Using data from the 1999-2002 rounds of the continuous National Health and Nutrition Examination Survey (NHANES), the inter-relationships between food insecurity, diet quality and body mass index (BMI) were examined. The impact of smoking and alcohol consumption behaviors were also examined. The relationship between BMI and food insecurity was found to be sensitive to the specification of control variables, such as age, income, and race and ethnicity. Smoking was directly associated with lower BMI for both men and women; while alcohol consumption was directly associated with lower BMI only for men. Smoking negatively affected food insecurity and diet quality, as measured by the Healthy Eating Index (HEI). For women, these indirect effects were... |

| The competitive position of three warm-season turf species commonly grown in the South (bermudagrass, centipedegrass, and zoysiagrass) is evaluated for a farm with 100 acres available to allocate to turfgrass-sod production. A multiperiod linear programming model is used to determine optimal mixes of grasses and resulting net returns for a seven-year planning horizon. Within current observable price ranges, variation in the prices of the different grasses has little impact on the profit-maximizing combination of grasses. Bermudagrass, with the shorter production cycle and positive influence on cash flow, dominates the higher-valued, longer-production-cycle alternative grasses. Availability of initial money capital from internal sources does not alter the... |

| Optimal crop and livestock mix was determined for a representative Alabama farm using a dynamic programming model. Results indicate that decisions concerning livestock production are highly influenced by the amount of cotton base available on the farm. In most cases, increasing cotton base results in less cattle production. The triple base provisions of the 1990 Farm Bill, however, may give some cotton farmers an incentive to produce more stocker cattle during the winter months. Research results also indicate that the availability of farm programs can alter the optimal enterprise mix on a farm with no beginning base in cotton. |

| Study uses a 16-question negotiation ethics survey to examine ethical attitudes among undergraduates at Oregon State, Auburn, Michigan State and Texas A&M Universities. About 600 students were surveyed. The results revealed that gender, age, religious activity and community service were major factors influencing ethical behavior. Family income, size of hometown, and most high school activities had virtually no influence on ethical behavior. |
