Popis: Total daily crisis calls were recorded over a 3-year period in Vancouver. Data from the first 2 years were examined using spectral analysis and regression analysis on sine and cosine functions of time to determine if periodicities existed over the time interval under consideration. Strong weekly, annual, and semiweekly cycles and weak monthly, semiannual, bimonthly, and 4-monthly cycles were uncovered. Very weak lunar relationships with the anomalistic cycle, half-synodic, and sidereal were also found. These lunar relationships were not consistent with beliefs in folklore or tradition. Data from the 3rd year were predicted with models with and without lunar variables. The addition of lunar variables was found to add nothing to the predictive value and, in fact, slightly worsened the predictions.
