Economists have long been fascinated by the sources of variations in the stock market. By the early 1970s a consensus had emerged among nancial economists suggesting that stock prices could be well approximated by a random walk model and that changes in stock returns were basically unpredictable. Fama (1970) provides an early, de nitive statement of this position. Historically, the random wa...
BACKGROUND Integrative medicine (IM) provides patient-centered care and addresses the full range of physical, emotional, mental, social, spiritual, and environmental influences that affect a person's health. IM is a "whole systems" approach that employs multiple modalities as opposed to an isolated complementary therapy. Thus, studying outcomes of IM is more challenging than evaluating an isola...
Background: Anode heel effect refers to reduction of radiation intensity in the anode side of X-ray tube. This variation in radiation intensity across the anode-cathode of X-ray tube can be benefited for decrease radiation exposure in some radiological examinations. The aim of this study was to evaluate the effect of anode heel orientation on the radiation dose received by the testes in male pa...
It is becoming increasingly important for clinicians to identify a safer intramuscular (IM) injection site in the deltoid muscle because of possible complications following the vaccine administration of IM injections. We herein examined 4 original IM sites located on the perpendicular line through the mid-acromion to establish a safer IM injection site. Thirty healthy volunteers participated in...
This report investigates the issue of selecting and scaling ground motions as input excitations for response history analyses of buildings in performance-based earthquake engineering. Many ground motion selection and modification (GMSM) procedures have been developed to select ground motions for a wide variety of objectives. This report focuses on the selection and scaling of single, horizontal...
