The relationship between culture and administrative reform is another topic that can foster comparison among countries (Schedler and Proeller 2007; Bowornwathana 2007). "Evaluation of public sector reforms can become another unifying concept for comparative work (Wollmann 2003; Pollitt and Bouckaert 2003). The governance concept of "transparency" is a central one for comparison (Hood and Heald 2006) .
Thus, the pillars of the new CPA are different from those of the old CPA, which was closely connected to the field of comparative politics and had leaders who were mostly political scientists with a background in comparative politics. Public administration scholars play a much stronger role in the new CPA, which focuses more on public administration (Peters 1996). In this regard the new CPA fits well with the "Public Administration as Public Administration Paradigm," as put forth by Nicholas Henry (2004).
