“…The majority of these papers (30/42, 71.4 percent) were from the health and social sciences literature and had a mean of 2.8 (Table 1) (Allen 1992; Barnes, Pashby, and Gibbons 2002; Beersma et al 2003; Aram 2004; Cummings 2004; Hobman, Bordia, and Gallois 2004; Guimera et al 2005) authors/article, 59.5 percent of whom were from the social sciences. Of these papers, one‐third (14, 33.3 percent) were empirically based research about interdisciplinarity (Allen 1992; White 1999; Kone et al 2000; Sullivan et al 2001; Barnes, Pashby, and Gibbons 2002; Lattuca 2002; Beersma et al 2003; Morillo, Bordons, and Gomez 2003; Schulz, Israel, and Lantz 2003; Aram 2004; Cummings 2004; Hobman, Bordia, and Gallois 2004; Senior and Swailes 2004; Guimera et al 2005); the others were general discussions (Woollcott 1979; Jacobs and Borland 1986; Bloedon and Stokes 1994; Nissani 1997; Israel et al 1998; Lindauer 1998; Northridge et al 2000; Stead and Harrington 2000; Anderson 2001; Aagaard‐Hansen and Ouma 2002; Board of Health Care Services 2003; Frost and Jean 2003; Nyden 2003; Jacobson, Butterill, and Goering 2004; Slatin et al 2004), cases studies (Dodgson 1992; Rosenfield 1992; Bisby 2001; Higgins, Maciak, and Metzler 2001; Lantz et al 2001; Lattuca 2001; Cheadle et al 2002; Austin 2003; Baba et al 2004; Daniels 2004; Tennenhouse 2004) and one literature review (Berkowitz 2000). Eleven (26.1 percent) of the papers included an explicit definition of interdisciplinarity and only five papers (11.9 percent) described or cited any type of conceptual framework or theoretical underpinnings for their approach to interdisciplinary research (three distinct typologies, see Table 2).…”
