Recent observations have revealed that early-type galaxies (ETG) in clusters comprise an old galaxy population that is evolving passively. We review some recent observations from the ground and from the HST that show that ETG have undergone a significant amount of luminosity evolution. This evolution is traced by two projections of the fundamental plane (FP): the size-magnitude relation (SMR) a...

man's past condition is related to his present life and history means surveying the quality of the past activities whose traces remain in the present time. the main field of historical research is man's past life, the stages which have been put behind in the process of evolution and changes as well as progresses made in these stages. history is a means to provide human beings with a complete in...

In this paper we investigate the phenomenon of online social networking within organisations. While Internet Social Networking (ISN) as a public phenomenon has drawn considerable interest from the academic community, little knowledge exists about the potentials and modes of use of social networking sites (SNS) that emerge within organisations. We draw on three cases of SNS implementation and us...

The concept of alliance or preferably ‘alignment’, as I shall explain below – is central to the conduct of international politics, and thus the discipline of International Relations (IR). Duffield et al. (2008: 291) identify that ‘Alliances are one of the most significant phenomena in security studies and world politics more generally’, while Modelski (1963: 773) considers them ‘one of a dozen ...

In this article I locate some of the fundamental problems of self-determination within the context of an evolving international society. First, I argue that one particular manifestation of self-determination, that of national self-determination, is both a solution to the enduring problem of territorial legitimation in international relations as well as the source of subsequent challenges to ter...

Historically, issues of gender, race and the environment have received little attention in mainstream International Relations (IR) scholarship. Great strides have been made, however, in interrogating the inadequacies of the field in these areas and, similarly, in demonstrating the necessity of expanded definitions of security and violence in IR. Despite these strides, mainstream environmental s...

The evolution of codification within the increasing complexity and diversity of relations is examined within a triadic architectural frame of filiated hierarchical levels of both material organization and consciousness. Inertia and entropy are understood as basic forces within codal organization, and evolution is examined as a force of mediation between these two forces, operating to move energ...
