This paper is grounded in the empirical reality of a growing use of informationand communication technologies (ICTs) in public administrations. Generally, ICTs are being introduced in an organization in order to increase operational efficiency, quality, and transparency. But, besides these intended effects, the introduction of ICTs also leads to substantial changes in the power relationships am...

The work described in this article arises from two needs. First, there is still a need for providing more sophisticated database systems than just relational ones. Secondly, there is a growing need for distributed databases. These needs are adressed by fragmenting schemata of a generic object data model and providing an architecture for its implementation. Key features of the architecture are t...

Event-condition-action (or ECA) rules are used to capture active capability. While a number of research prototypes of active database systems have been built, ECA rule capability in Relational DBMSs is still very limited. In this paper, we address the problem of turning a traditional database management system into a full-fledged active database system without changing the underlying system. Th...

The aim of this paper is to provide insights into the interplay between contractual and relational governance in IT outsourcing arrangements. The study will demonstrate the value of the Foucauldian notion of “governmentality” into the examination of IT outsourcing relationships. Using this theoretical lens our study will attempt to show how the contract and the apparatus of governance it entail...

Nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. Since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. To reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

3. Technology We demonstrate a prototype toolkit called ITSE (Integrated Translation Support Environment), for interoperation and migration of heterogeneous database systems. Semantic Metamodel Major datamodels (network, relational, object-oriented) are represented in the metamodel as sets of logic predicates alon,g with mapping rules to establish equivalences between expressions in different m...

Research teams face complex leadership and coordination challenges. We propose shared authentic leadership (SAL) as a timely approach to addressing these challenges. Drawing from authentic and functional leadership theories, we posit a multiple mediation model that suggests three mechanisms whereby SAL influences team effectiveness: shared mental models (SMM), team trust, and team coordination....
