The economic viability of a supersonic commercial transport airplane would be much enhanced if it could fly supersonically over land. Efforts to design an airplane to produce a minimized sonic boom at the ground require knowledge of the impact of ,sonic booms on people. Loudness, being a fundamental and well-understood characteristic of human he_zrin9, was chosen as a means of quantifying the m...

Test bias, in contrast to test fairness, is best conceptualized in validity terms amenable to statistical analysis. Evidence of predictive validity may be most salient in many situations. Evaluation of predictive bias is generally operationalized via linear regression. Potthoff (1978) provided an efficient and parsimonious regression bias procedure that allows both simultaneous and separate tes...

trabeculectomy is the most common procedure performed in glaucoma patients to reduce intraocular pressure for a long-time period. this intervention can cause alterations in axial length (0.1-0.9 mm), anterior chamber depth (0.11±0.22 mm), and keratometry readings (1.07±1.14 diopter). these changes may linger for more than one year and may negatively affect the precision of intraocular lens powe...
