Delegation versus Authority by Daniel Krähmer The paper studies the role of delegation and authority within a principal-agent relation in which a non-contractible action has to be taken. The agent has private information relevant for the principal, but has policy preferences different from the principal. Consequently, an information revelation problem arises. We contribute to the literature by ...

While standard locking libraries are common and easy to use, delegation algorithms that offload work to a single thread can achieve better performance in multithreaded applications, but are hard to use without adequate library support. This paper presents an interface for delegation locks together with libraries for C and C++ that make it easy to use queue delegation locking, a versatile highpe...

Some designers of class-based object oriented languages choose not to support multiple inheritance. As a result, programmers often resort to ad hoc workarounds. The most common of these workarounds is delegation. Even delegation is tedious and error prone, however: We believe that language designers who choose against multiple inheritance should consider automating delegation in order to allevi...

It has been recognized in several works that a slice of behavior affecting a set of collaborating classes is a better unit of reuse than a single class. Different techniques and language extensions have been suggested to express such slices in programming languages. We propose delegation layers, an approach that scales the OO mechanisms for single objects, such as delegation, late binding, and ...

Access control is a fundamental and essential mechanism to maintain security in ubiquitous computing (UbiComp). Flexibility is an important property for general access control system, which can be achieved by access or authority delegation. Existing delegation mechanisms are "subject-centered", thus in order to make sure that the unavailability of some users does not prevent the syste...

Delegation of decision-making has important implications for firms’ performance. We build a simple model predicting that decentralized firms are more involved in R&D, and use data from the Italian manufacturing industry to document a positive correlation between delegation and R&D spending. This result is robust to controlling for the determinants of R&D such as human capital, capital intensity...

In emerging ubiquitous computing, related nomadic users often perform similar tasks and share the same computing infrastructure. This means that security of the shared resources is of prime importance. Frequent delegation of tasks among users must be anticipated as most nomadic environments are hectic and very dynamic. A delegation mechanism with a slightly complicated user interface will not o...

Delegation is a major goal when a real scalable distributed authorization system is needed. However, the uncontrolled use of delegation statements can become an important security threat; for instance, any user could improperly obtain over a resource the same privileges as the owner of that resource. Therefore, delegation solutions should include a mechanism to control the delegation of privile...
