A cross- specialty analysis of relative values in the new version of Iranian relative values for physician
Background: The new version of relative values of diagnostic medical services was published in 2014. It was criticized that the previous edition was suffering from an imbalance between relative values related to various specialties and sub-specialties. The main aim of the new edition of the book was to address this problem by providing more balance relative values related to various specialties...
متن کاملEstimating the relative contributions of virulence factors for pathogenic microbes.
Many pathogenic microbes have multiple virulence factors that can cause damage to the host and thus contribute to an overall virulence phenotype for that organism. Although current techniques are suitable for demonstrating that a particular microbial characteristic contributes to virulence, no formal approach for defining the relative contributions of multiple virulence factors to overall virul...
متن کاملRelative area and relative luminance combine to anchor surface lightness values.
The anchoring of lightness perception was tested in simple visual fields composed of only two regions by placing observes inside opaque acrylic hemispheres. Both side-by-side and center/surround configurations were tested. The results, which undermine Gilchrist and Bonato's (1995) recent claim that surrounds tend to appear white, indicate that anchoring involves both relative luminance and rela...
متن کاملThe relative values of cereal proteins for chick growth.
Many studies have been undertaken in the past half century to assess the relative values, for production, of the proteins in those cereals most commonly used in the feeding of non-ruminant animals. Cereals are usually regarded in the first place as a major source of energy, but they incidentally supply from oneto two-thirds or more of the dietary protein requirement. For poultry the proportion ...
متن کاملConfidence intervals for seasonal relative risk with null boundary values.
In evaluating the relative risk of seasonality, the null value is a boundary value. In this case, tests for the null hypothesis exist, but standard methods for confidence intervals are not appropriate. We provide a method for constructing confidence intervals under the circular normal model. The proposed confidence intervals are valid for all values of the underlying seasonal risk if the model ...
