An important argument in favor of the encyclical theory of the epistle to the Ephesians is based upon the peculiarities found in the epistle itself. Yet these unusual features (e.g., the lack of personal greetings, the unusual statements in 1:15, 3:2, and 4:21, etc.) can all be satisfactorily explained in the light of an original Ephesian destination. After an examination of early scribal habit...

The paper presents a semiotic approach to the study of knowledge creation and sharing processes. These processes are aimed to generate goal-oriented knowledge system (GOKS) in different domains. A GOKS is generated by an expert collective that creates new meanings using a changeable constellation of signs including personal (expert), collective, and conventional signs, their sign-forms and sign...

Single sign-on and delegation of privileges are fundamental tenets upon which e-Infrastructures and Grid-based research more generally have been based. The realisation of single sign-on and delegation of privileges in accessing resources such as the UK e-Science National Grid Service (NGS http://www.ngs.ac.uk) and other national facilities is typically facilitated by X.509-based Public Key Infr...

In this paper we sketch a framework for multi-actor simulation of an organization. In contrast to many approaches to multi-actor simulation, we design the actors as cognitively plausible actors. The interaction and cooperation of the actors is based on social constructs. In elaborating a cognitive perspective on actors, we use the cognitive architecture ACT-R for modelling the individual actors...

Natural selection is an important factor influencing variation in the human genome, but most genetic studies of natural selection have focused on variants with unknown phenotypic associations. This trend is changing. New studies are rapidly revealing the effects of natural selection on genetic variants of known or likely functional importance.

We describe the concept of automatic authentication for cloud-based services via the use of a client-centric solution for small and medium enterprises (SMEs). In previous work we have introduced the Identity Management Machine (IdMM) which is designed to handle the interaction between a client’s identity directory and various cloud identity management systems. We now further refine this machine...

Preface For as long as I can remember, I have been interested in languages. Sign languages especially fascinate me, because they are natural languages using a different modality: sign languages use images as the vehicle for information. This has strange implications: in sign language, it is easy to have a conversation with someone at the other side of a crowded room. On the other hand, it is im...
