Background: This study investigated the association between vitamins intakes and risk of gastric cancer (GC) among Iranian population. Methods: In this hospital-based case-control study, 178 pathologically confirmed GC patients and 276 healthy controls were interviewed to answer a valid diet history questionnaire. Unconditional logistic regression, in which potential confounders were taken i...

Overall, the risk assessment documents provide a thorough evaluation of potential risks for a very complicated site. I commend the authors. My comments are intended to be a source of constructive criticism from an individual who has prepared several assessments for other large Superfund sites as well. Since risk assessment is an evolving, flowing process, there are varying approaches that can b...

Moody’s KMV method is a popular commercial implementation of the structural credit risk model pioneered by Merton (1974). It is an algorithm for estimating the unobserved asset value and the unknown parameters required for implementing such a model. This estimation method has found its way to the recent academic literature, but it has not yet been formally analyzed to assess its statistical pro...

In 1983, the Michigan legislature adopted changes in the Frozen Desserts Act, Act 298, Public Acts of 1968, as amended, which eliminated the need for the Michigan Department of Agriculture (MDA) to license, sample and inspect those facilities which manufactured frozen desserts in a food service setting. Since all food service establishments are licensed and inspected by the local health departm...

Moody's endorses the Basel Committee's proposal to use banks' internal risk assessments to re®ne the Basel Accord's risk weights on bank assets and commitments. External risk assessments, such as Moody's credit ratings, will likely play a supporting role as direct inputs into banks' internal rating systems and as tools for benchmarking and validating those systems. However, the widespread use o...

The association between community-aggregated levels of peer and individual risk and protective factors and prevalence of adolescent substance use was examined in repeated cross-sectional data among youth in 41 communities ranging in population from 1,578 to 106,221. The association between community levels of these peer and individual risk and protective factors in 2000 and substance use 2 year...

Many lizard species use caudal autotomy to escape entrapment. Conspicuous coloration may increase the likelihood of being attacked, but if that attack can be directed towards the autotomous tail this may ultimately increase the chances of the lizard surviving a predatory attack. We tested the hypothesis that brightly-colored function to divert predatory attention away from the head and body usi...
