We develop an informational model of judicial decision-making in which deference to precedent is useful to policy-oriented appellate judges because it improves the accuracy with which they can communicate legal rules to trial judges. Our simple model yields new implications and hypotheses regarding conditions under which judges will maintain or break with precedent, the constraining effect that...

The software architecture requires interoperable security mechanisms. This article focuses on applying security requirements to service-oriented solution design. SOA security is very much concerned with what the system is supposed to do and what can go wrong. This article presents the service-oriented approach — security services that can be developed and tested and applied against many types o...

This paper describes the incremental weaving implementation of Apostle, an aspect-oriented language extension to Smalltalk modelled on AspectJ. Apostle implements incremental weaving in order to make aspect-oriented programming (AOP) a natural extension of the incremental edit-run-debug cycle of Smalltalk environments. The paper analyzes build dependencies for aspect declarations, and shows tha...

The provision of the right data with appropriate quality according to the needs of decision makers or automated processes is crucial for successful operations of companies and government agencies. Management Information Systems, Decision Support Systems, Executive Information Systems, interactive online analysis (OLAP), data mining, dashboards and recently predictive analytics are examples for ...

Many Spatial Decision Support Systems (SDSSs) have been developed for environmental and natural resources decisionmaking in recent years. However, an important limitation of the SDSS applications is that they are not interoperable. Several issues prevent the further development of SDSS applications such as the incapability of sharing and reusing existing heterogeneous data and geoprocessing. Th...

service interfaces, distributed ownership and cross-domain operations introduce new challenges for the implementation of compliance controls and the assessment of their effectiveness. In this paper, we analyze the challenges for automated support of the enforcement and evaluation of IT security controls in a SOA. We introduce these challenges by means of an example control, and outline a method...

In the service computing paradigm, a service broker can build new applications by composing network-accessible services offered by loosely coupled independent providers. In this paper, we address the admission control problem for a a service broker which offers to prospective users a composite service with a range of different Quality of Service (QoS) classes. We formulate the problem as a Mark...

Separating decision modelling from the processes concern recently gained significant support in literature, as incorporating both concerns into a single model impairs scalability, maintainability, flexibility, and understandability of decisions. Most notably introduction Decision Model Notation (DMN) standard by Object Management Group provides suitable solution for externalising decisions auto...

Decision making and knowledge intensive work requires information supply tailored to the need of the user in question. Context management is considered a key contribution to this objective. The paper investigates context definitions and representations from two different viewpoints: information demand analysis and decision support. Discussion and comparison of these viewpoints includes enterpri...
