Family development theory

Explanation:

Although this theory´s idea of family functioning as a dynamic system that goes through a set of specific stages has been useful in a past period, its incompatibility with nontraditional family structures, meaning those that transcend the classic family unit of a wife, a husband, and two children, make it outdated in the current state of family constructs that show a lot more diversity. The family systems theory´ focuses on the interconnectedness between the family members as well as their connections to their community, and therefore is more suitable to analyze different family structures.

classical republicanism, also known as civic humanism, is a form of republicanism  developed in the renaissance inspired by the governmental forms and writings of  classical  antiquity, especially such  classical  writers as aristotle, polybius, and cicero.
