Permission-role assignments (PRA) is one important process in Role-based access control (RBAC) which has been proven to be a flexible and useful access model for information sharing in distributed collaborative environments. However, problems may arise during the procedures of PRA. Conflicting permissions may assign to one role, and as a result, the role with the permissions can derive unexpect...

In this paper we describe the Spanish electricity industry and its current regulatory regime. Special emphasis is given to the description and discussion of market design issues (including stranded cost recovery), the evolution of market structure, investment in generation capacity and network activities. We also provide a critical assessment of the 1997 regulatory reform, which did not succeed...

Nepal’s political system is in rapid transition following the end of the Maoist People’s War and overthrow of the King in 2006, and the subsequent formation of a Federal Democratic Republic in 2007. A radical-left coalition, led by a Maoist party in 2008, won an electoral majority (surpassing the two biggest parties that ruled the country in the post 1990 period). The conflict period animated t...

Attempts to develop open process standards, such as Rosetta Net, have had limited success in finding wide-spread adoption. Standardization of interorganizational business processes, previously viewed as aiding interorganizational collaboration, is shown to impede that collaboration in service contexts. We show that the modeling methods used to standardize inter-organizational processes fails to...

The digital economy is based on data sharing yet citizens have little control about how their personal data is being used. While data management during web and app-based use is already a challenge, as the Internet of Things (IoT) scales up, the number of devices accessing and requiring personal data will go beyond what a person can manually assess in terms of data access requests. Therefore, ne...

The analytic enquiry of deontic modalities (obligatory, permitted, etc.) has been developed before and independently of the logic modelling of mental attitudes, of cognitive agent architecture, and of social interaction; it taken place following the blue print of non-deontic modalities (necessary; possible). We might consider this kind of approach and this use of the logic as basically anti-men...

It is a standard feature of all organisations that designated agents, usually when acting in specific roles, are empowered by the organisation to create specified kinds of states of affairs — as when, for instance, a priest declares a couple as married and thereby makes it so in the eye of the church, or when a head of department assigns one of his subordinates to a particular project, or when ...

Our goal is to formalize what "having the permission to say" means. We adapt the dynamic logic of permission considered by van der Meyden in the particular case where atomic actions are public and truthful announcements. Hence, we extend the logic of public announcements introduced by Plaza, that enables us to express the ways agents update their knowledge after public and truthful announcement...
