After discussing some of the regional sources of insecurity past and present, and introducing the debate about the so-called ‘regionalization of security’, it fo...

The globalisation of the software market has changed the contextual boundaries of IS research and practices to include the wider societal context. Some attempts have been made to document differences amongst IS professionals from different nations, but most of these studies have compared IS or IS related issues in only two countries mainly by using an ethnocentric approach (the same research is...

Abstract Let $\textsf{T}$ be a triangulated category with shift functor $\Sigma \colon \textsf{T} \to \textsf{T}$ . Suppose $(\textsf{A},\textsf{B})$ is co-t-structure coheart $\textsf{S} = \Sigma \textsf{A} \cap \textsf{B}$ and extended $\textsf{C} \Sigma^2 \textsf{B} \textsf{S}* \textsf{S}$ , which an extriangulated category. We show that there bijection between co-t-structures $(\textsf{A}^{...

In the 1970's, Salce introduced notion of a cotorsion pair classes abelian groups, and asked whether every such is complete (that is, has enough injectives projectives); we refer to this as Salce's Problem (for Ab). We prove that it consistent, relative consistency Vop?nka's Principle (VP), answer affirmative. Combined with previous result Eklof Shelah , shows for Ab, in fact R-Mod when R $R$ h...
