Let $pounds$ be the category of locally compact abelian groups and $A,Cin pounds$. In this paper, we define component extensions of $A$ by $C$ and show that the set of all component extensions of $A$ by $C$ forms a subgroup of $Ext(C,A)$ whenever $A$ is a connected group. We establish conditions under which the component extensions split and determine LCA groups which are component projective. ...

We discuss a special aspect of agents placed in a social network. If an agent can be seen as comprising many components, the expressions and interactions among these components may be crucial. We discuss the role of patterns within the environment as a mode of expression of these components. The stability and identity of an agent is derived as a function of component and component-pattern ident...

Despite initial technical barriers having been overcome, organizational wide component reuse has not enjoyed universal acceptance. Research has identified social and organizational factors as probable causes. This paper describes the Social Factors for Reuse Model (SFR Model), a predictive capability model based on Keidel’s triadic model of the organization. It determines an organization’s read...
