Systematic Training for Effective Parenting Systematic Training for Effective Parenting Systematic Training for Effective Parenting (STEP) is a parent education program published as a series of books. STEP was developed and published by the psychologists Don Dinkmeyer Sr., Gary D. McKay and Don Dinkmeyer Jr. The publication was supplemented by an extensive concept for training and proliferation. STEP has reached more than 4 million parents and has been translated into Spanish, French, German, and Japanese. Korean and Chinese adaptations are in progress. STEP is based on Alfred Adler's individual psychology and the work of the psychologists Rudolf Dreikurs and Thomas Gordon. An evaluation of the
Effective atomic number possible to obtain a much more accurate single-valued Z by weighting against the spectrum of the source. The effective atomic number for electron interactions may be calculated with a similar approach; see for instance Taylor "et al." 2009 and Taylor 2011. The cross-section based approach for determining Z is obviously much more complicated than the simple power-law approach described above, and this is why freely-available software has been developed for such calculations (Taylor "et al." 2012). Effective atomic number Effective atomic number has two different meanings: one that is the effective nuclear charge of an atom, and one that calculates
