Ecological Systems Theory
Urie Bronfenbrenner is generally regarded as one of the world's leading scholars to focus on the interplay between research and policy on child development. Bronfenbrenner suggests child development research is better informed when institutional policies encourage studies within natural settings and theory finds greater practical application when contextually relevant. This perspective is well defined by Bronfenbrenner, who states, "...basic science needs public policy even more than public policy needs basic science" (Bronfenbrenner, 1979, p. 8, italics in original). It is from this vantage point that Bronfenbrenner conceives his primary contribution, Ecological Systems Theory, in which he delineates four types of nested systems. He calls these:
- the microsystem (such as the family or classroom);
- the mesosystem (which is two microsystems in interaction);
- the exosystem (external environments which indirectly influence development, e.g., parental workplace);
- and the macrosystem (the larger socio-cultural context).
He later adds a fifth system, called the Chronosystem (the evolution of the four other systems over time).

“The theory of the Communists may be summed up in the single sentence: Abolition of private property.”
—Karl Marx (18181883)
“Could it not be that just at the moment masculinity has brought us to the brink of nuclear destruction or ecological suicide, women are beginning to rise in response to the Mothers call to save her planet and create instead the next stage of evolution? Can our revolution mean anything else than the reversion of social and economic control to Her representatives among Womankind, and the resumption of Her worship on the face of the Earth? Do we dare demand less?”
—Jane Alpert (b. 1947)
“What is most original in a mans nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldnt have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
