In the midst of today's global crisis, a true urgent need for competitive, secure and sustainable business initiatives arises, in the sense of implementing a strategy that focuses on certain key points, predicts and aims to make a profit, while, at the same time minimizes the risks, the loss of financial rights and of course the environmental pollution. The purpose of this work is to integrate learning into the world of business enterprises by exploring their common features, their potential relations as well as the impact of impending mathesis to an entrepreneurial initiative. From a marketing, financial and operational viewpoint, any contemporary successful business requires multimodality, polymorphism and adaptability to socioeconomic and spatiotemporal changes without loosing its value, for which, learning seems to be an inherent element. In that prospect, any learning procedure is not subjected to legal restrictions, its kickoff is based on the human senses, simulates recyclable and reusable energy, is risk–free and so on, qualities considered as being essentialia negotii, that are gained ex tunc and act ex nunc for a general secure entrepreneurial activity that will be adaptable to any new and rapidly changing data as well.

This paper presents Policy-based Federation (PBF) architecture for interworked Future Internet Virtualized Infrastructures (VIs). Each VI is an individually managed autonomous domain. Users may request slices of virtual resources across the federation, managed and controlled via inter-domain policies that abide by agreed upon federated SLAs. The key component of our PBF architecture is a Policy Service, which provides support for intra-domain policies (Obligation, Authorization, Role-Based Access Control) and for inter-domain Delegation policies. Delegation policies reserve resources in remote domains, update the number of resources exchanged, set alien domain obligations for cross-domain resource provisioning and define the exchange of internal domain information through the execution of remote semantic queries. Key to the architecture is the PBF Policy Ontology that specifies common federation concepts within the context of a user slice and the PBF services that trigger management actions. A prototype of the proposed architecture was developed and deployed in a European Future Internet federated testbed.

Purpose – The purpose of this paper is to explore and present a higher education initiative towards the training and development of Eastern European citizens, who migrate to Greece, in pursuit of bettering their economic conditions and, simultaneously, become evolving social entities, adaptable to heterogeneous environments. Design/methodology/approach – Motivated by the motto “education for all”, the initiative is based on data drawn from local and public authorities and interviews that were carried out with immigrants, mainly from Albania and Ukraine. Findings – This paper proposes a learning policy and training mechanism for foreigners and the establishment of a Mediator Office providing educational services. Research limitations/implications – Further efforts are necessary to improve the teaching content in order to be in full conformity with the characteristics and requirements of non-native learners. Practical implications – Some of the constraints hampering the implementation of this initiative are the lack of the necessary financial resources, the absence of legal framework, as well as the shortage of bilingual adult training and education instructors. Originality/value – There have been limited autonomous educational programmes concerning immigrants ' lifelong learning provided by the Greek Ministry of Education, focused mainly on the Greek language and history learning. This work introduces a novel educational structure, which may be established in any higher education institution and which will involve anyone in any kind of subject, anytime and anywhere.
