Model-based refinement of security policies in collaborative virtual organisations

Abstract: Policy refinement is the process of deriving low-level policies from high-level policy specifications. A basic example is that of the refinement of policies referring to users, resources and applications at a high level, such as the level of virtual organsiations, to policies referring to user ids, resource addresses and computational commands at the low level of system and network environments. This paper tackles the refinement problem by proposing an approach using model-to-model transformation techniques for transforming XACML-based VO policies to the resource level. Moreover, the transformation results in deployable policies referring to at most a single resource, hence avoiding the problem of cross-domain intereference. The applicability of our approach is demonstrated within the domain of distributed geographic map processing.

Snoozing Democracy: Sunset Clauses, De-Juridification, and Emergencies

Abstract: In the last decades, we have witnessed two contradictory tendencies in lawmaking throughout the Western world: On the one hand, there is a tendency to 'juridify' almost every single aspect of society, ensuring that almost no detail is left unregulated. On the other, at times of economic or political crisis, a part of society is 'de-juridified', that is, law disappears strategically as multiple rules are temporarily put on hold, rights are suspended and courts are deactivated. This Article focuses on this ambivalence and on the role played by sunset clauses to operationalize both temporary juridification and de-juridification. Sunset clauses have often been used in common law and, more recently, in civil law countries to 'juridify' and 'de-juridify' since these legislative provisions provide that a specific piece of legislation shall expire automatically on a specific date. These dispositions can be used not only, to enact exceptional and temporary emergency measures (e.g. temporary policies to provide financial assistance to firms) but also to remove procedural obstacles that stand in the way of rapid decisionmaking. Temporary de-juridification through sunset clauses might seem at first sight an effective method to tackle emergencies, guaranteeing that extraordinary powers do not become entrenched. However, this Article demonstrates that in the past rights and institutions have been too easily suspended at times of crisis and temporary measures have often been extended beyond the original critical periods. Not surprisingly, this has had pernicious effects on the principle of separation of powers and the protection of human rights. Although the mentioned ambivalence of de-juridification at times of crisis has been perceived as a problem in multiple jurisdictions, not much attention has been devoted to it in the legal literature. This Article fills this gap by analyzing the nature and functions of temporary de-juridification through sunset clauses and explaining the risks of hasty de-juridification. This Article provides a historical and comparative account of the implementation of temporary de-juridification through sunset clauses. Based on these lessons, we suggest a normative framework to help rethink particularly the temporary de-juridification of human rights and address the negativity which is often associated with sunset clauses.

Outsourcing Innovation: A Comparison of External Providers at Siemens

Abstract: Innovation outsourcing has become a widespread practice in R&D management. Five types of innovation partners are the most widely discussed: universities and R&D institutes, customers, suppliers, competitors, and high-technology start-up companies. Previous work has compared these innovation sources with respect to general strengths and weaknesses and main areas of use. The current paper uses 24 case studies from Siemens practice to characterize specific operational management challenges and success drivers in outsourcing innovations from these five sources. We identify five success drivers that are common to all innovation sources and should be ensured by management whenever possible. In addition, we find that each innovation source has several specific success drivers. Finally, the management challenges shift when a mature technology is sourced versus a novel, embryonic technology. Our results give managers guidance on how to adapt the operational management of an innovation outsourcing project to the source of the external knowledge and the technology maturity stage.

Abstract: Using event study methodology, we show that the announcement of supply chain management (SCM) applications has a positive impact on the market value of firms. When SCM applications are disaggregate...

The Provisional Constitution of the Federal Republic of Somalia: Process, Architecture, and Perspectives

Abstract: Much ink has been spilled over the Republic of Somalia. Somaliland became synonymous for pariah state and was in the spotlight and in the immediate interest of international organisations and intergovernmental bodies due to the continuous deadlock and unsolvable political turmoil. Quite recently, the country attracted the interest of the international community as a new Constitution was adopted, and thus the Republic of Somalia joined the club of numerous African countries, such as Tunisia, Egypt, South Sudan, and Libya with a new constitutional order. The Constitution was adopted with the aim of terminating a long period of tensions, warfare, political turmoil, and often chaos, by establishing efficient political institutions and introducing governance that is more responsive and accountable to its people. In this Note, I review and evaluate the Somali Constitution, while the aim is to provide an overview of the role of the constitutional drafting process and the new constitution in the political era of the post conflict Somalia. The analysis begins by considering the recent political environment of Somaliland, and the whole process that led to the new Constitution. This will be followed by a detailed discussion about the major components of the Constitution, elaborating on the architecture of the polity. Finally the last part will be devoted on an attempt to highlight the benefits and the deficits of the new constitution.
