“…Several studies provide refinements of the methods for DFM/A and DFX. Some provide indications of the effects of these based on numerical simulation (Curran et al, 2007;Das & Kanchanapiboon, 2011;Madan, Rao, & Kundra, 2007;Taylor, 1997), whereas other studies provide empirical support for such refinements (Bevilacqua, Ciarapica, & Giacchetta, 2007;Boer & Logendran, 1999;Chan & Lewis, 2000;Dowlatshahi, 1995;Ijomah, McMahon, Hammond, & Newman, 2007;Lin, Lee, & Bohez, 2012;Lu & Wood, 2006;Pullan, Bhasi, & Madhu, 2012).…”
