QUANTIFYING GAINS TO RISK DIVERSIFICATION USING CERTAINTY EQUIVALENCE IN A MEAN-VARIANCE MODEL: AN APPLICATION TO FLORIDA CITRUS

The marginal benefit and cost of diversification for Florida orange producers is analyzed using certainty equivalents. Results indicate that for moderate and high levels of risk aversion, diversification into strawberry, grapefruit, or additional orange production is not optimal. However, moderately risk averse Florida orange producers can gain by diversifying into grapefruit production if the annual amortized fixed costs can be reduced by as little as 10 percent.Risk and Uncertainty,

Associations Between MMPI-2-RF Scale Scores and Institutional Violence Among Patients Detained Under Sexually Violent Predator Laws

Sexually violent predator (SVP) laws allow the postprison civil commitment of sex offenders to a secure psychiatric hospital because of mental abnormality and posing a serious risk to public safety. Research on predictors of future institutional violence in this population is lacking because adequately sized samples are difficult to obtain. In the current study, we examined psychological predictors of future institutional violence in a sample of 171 psychiatrically hospitalized males detained or civilly committed under an SVP laws. Using the Minnesota Multiphasic-Personality Inventory-2–Restructured Form (Ben-Porath & Tellegen, 2008/2011), we found that scales assessing thought dysfunction, emotional dysregulation, and externalizing behaviors were associated with future physical violence at the hospital. Relative risk ratio analyses indicated that SVPs producing elevations on these scales were at 1.5–2.5 times greater risk of future physical violence than those without elevations. Overall, the results suggest the Minnesota Multiphasic-Personality Inventory-2–Restructured Form is associated with future institutional violence among SVPs. Implications and limitations of these findings are discussed

Analytic Quantization of the QCD String

We perform an analytic semi-classical quantization of the straight QCD string with one end fixed and a massless quark on the other, in the limits of orbital and radial dominant motion. We compare our results to the exact numerical semi-classical quantization. We observe that the numerical semi-classical quantization agrees well with our exact numerical canonical quantization.Comment: RevTeX, 10 pages, 9 figure

Visible Discrimination of Broadband Infrared Light by Dye-Enhanced Upconversion in Lanthanide-Doped Nanocrystals

Optical upconversion of near infrared light to visible light is an attractive way to capture the optical energy or optical information contained in low-energy photons that is otherwise lost to the human eye or to certain photodetectors and solar cells. Until the recent application of broadband absorbing optical antennas, upconversion efficiency in lanthanide-doped nanocrystals was limited by the weak, narrow atomic absorption of a handful of sensitizer elements. In this work, we extend the role of the optical antenna to provide false-color, visible discrimination between bands of infrared radiation. By pairing different optical antenna dyes to specific nanoparticle compositions, unique visible emission is associated with different bands of infrared excitation. In one material set, the peak emission was increased 10-fold, and the width of the spectral response was increased more than 10-fold
