Risk of sexual recidivism as a function of age and actuarial risk

The study of risk for sexual recidivism has undergone substantial development in recent years. The foundation for advances in this area has been the use of actuarial measures to identify subgroups of offenders with different observed rates of sexual re-offending over time. An unresolved issue within this research area has been the moderating function of age in the assessment of risk. The current study examined sexual re-offending as a function of age and actuarial risk in a large sample of sexual offenders released from prison between 1990 and 2004. There was an overall decrease in the rate of sexual re-offending over the age of 50. However, a small group of offenders from the higher actuarial risk categories of the older age groups continued to re-offend at higher rates than their lower-risk peers. <br /

THE PROFITABILITY OF SUSTAINABLE AGRICULTURE ON A REPRESENTATIVE GRAIN FARM IN THE MID-ATLANTIC REGION, 1981-89

A long-term whole-farm analysis compared conventional and low-input farming systems. Data from a nine-year agronomic study at the Rodale Research Farm, Kutztown, Pennsylvania, were used to analyze profitability, liquidity, solvency, and risk on a representative commercial grain farm. Conventional and low-input farms participating in government programs are the most profitable scenarios, followed by conventional and low-input farms not participating in government programs. All farms increased their net worth. The low-input approach is advantageous for risk-averse farmers using a safety-first criterion.Crop Production/Industries, Environmental Economics and Policy,

Using your soil test results

"To use your soil test report to the best advantage, you need to understand the information it provides. With the proper soil test interpretations and suggested fertilizer treatments, you will have a fertilizer program for maximum profitable crop production."--First page.Daryl D. Buchholz, James R.

Willingness to Pay for a Potential Insurance Policy: Case Study of Trout Aquaculture

Using trout producer survey data and the contingent valuation method, we estimate willing-ness to pay for a potential insurance policy. The survey was conducted in 2005 across the United States; 268 producers completed the survey instrument, resulting in a response rate of 81 percent. Design of the contingent valuation method takes into account two coverage levels and four premium rates. Using standard willingness-to-pay techniques, we assess the premium rate that producers with varying practices and regions are willing to pay for two different cov-erage levels of insurance. In general, trout producers appear willing to pay premium rates of 2 to 11 percent for these coverage levels.willingness to pay, subjective elicitation and survey data, aquaculture trout insurance, Livestock Production/Industries, Risk and Uncertainty,
