In this paper, we develop Morse theory, which allows us to determine topological information about manifolds using certain real-valued functions defined on the manifolds. We first prove the Morse lemma, which says that, near critical points, such functions can be written in a useful way that gives us topological information. We then show how the homotopy type of the manifold is related to the i...

One of the great strengths of contemporary work in moral development is its lifespan orientation and the long legacy of theory and research on which contemporary scholars can draw. Moreover, there has been a recent resurgence of interest in the development of moral character and moral personality that derives, in part, from a realization of how the growth of moral awareness is tied to the devel...

Today, most of the big cities or metropolises around the world have been encountering with the problem of informal habitation. The present study, thus, tries to focus on the role of endogenous development in such type of habitation process. For that matter, the paper takes into account architectural programming and urbanism as its theoretical framework because the endogenous development is rela...
