Rather, ecological variables are necessary to examine structural, contextual, and sociological effects on human behavior and disease development. Schwartz, 1994 b, p. 823 Many attempts have been made to define (e.g., Rohner, 1984) and then to measure culture. Given the classic definition of culture provided by Kroeber and Kluckhohn (1952), this mapping has usually been made by using values. The most widely known value mapping is the work of Hofstede (1980), whose four value dimensions of Individualism-Collectivism, Power Distance, Uncertainty Avoidance, and Masculinity-Femininity are used as organizing and explanatory constructs in many disciplines. Tapping values salient to Chinese people, the Chinese Culture Connection (1987) has identified one additional dimension to the Hofstede four: Confucian Work Dynamism, or short-term versus long-term orientation (Hofstede, 1991). All five dimensions of culture-level values have provided the conceptual impetus for numerous cross-cultural studies. Several major cross-cultural projects have been conducted subsequent to Hofstede's (1980) groundbreaking work. With his theory-derived value survey, Schwartz (1994 a) has identified seven culture-level dimensions, namely, Conservatism, Intellectual Autonomy, Affective Autonomy, Hierarchy, Egalitarian Commitment, Mastery, and Harmony. Smith, Dugan, and Trompenaars (1996) have identified two reliable value dimensions at the cultural level from their analysis of managerial values: Egalitarian Commitment versus Conservatism, and Utilitarian Involvement versus Loyal Involvement. Smith and Bond (1998, Ch. 3) concluded that these different value surveys have produced convergent results, lending support to the validity of the cultural dimensions originally identified by Hofstede (1980). Recently, House and his associates (2003) have orchestrated a major project to identify cultural dimensions across 62 countries. A distinctive feature of this multicultural project is that values associated with leadership were measured concurrently with ideal and actual leadership behaviors. The House team has identified nine culture-level dimensions:
