The Internet has grown to become a major component of the global world-wide network infrastructure, linking millions of users. We rst address the need for an electronic market and match-making between consumers and providers on the Internet for the stock photo industry. We discuss business issues and highlight technologies required to support an electronic market for image exchanges on the glob...

The GENSS project has developed a flexible generic brokerage framework based on the use of plug-in components that are themselves web services. The focus in GENSS has been on mathematical web services, but the broker itself is domain independent and it is the plug-ins that act as sources of domain-specific knowledge. A range of plug-ins has been developed that offer a variety of matching techno...

We examine security analysts’career concerns by relating their earnings forecasts to job separations. Relatively accurate forecasters are more likely to experience favorable career outcomes like moving up to a high-status brokerage house. Controlling for accuracy, analysts who are optimistic relative to the consensus are more likely to experience favorable job separations. For analysts who cove...

The main problem studied in this paper is how to design an efficient method for information brokerage in sensor networks that do not use an overlay layer to organize the network and when geo-coordinates are not provided. We present a method for the solution of this problem using Directional Random Walks (DRWs) which main purpose is to construct a straight path of relaying nodes in the network. ...

For the first time, development of freight forwarding, as an economic activity in Serbia, is analysed this paper. At beginning, a brief literature review on origin and evolution forwarding given, well research motivation goal. Currently, there any study that systematically deals with historical Serbia. The period before Second World War almost entirely unknown. main goal presented to highlight ...

Automatic Grid resource discovery and brokerage shields the Grid middleware complexities from the Grid users and leads towards an invisible but simple and robust Grid. Realizing this vision requires a machine understandable resource description and powerful correlation 1 mechanism. Semantic technologies like ontologies provide vocabularies with explicitly defined, unambiguously understandable a...

The First Welfare Theorem fails to hold for standard pure exchange overlapping generations economies because no agent exploits the profit opportunities which can arise from mediating intertemporal trade. This paper modifies the standard economy by introducing an optimizing corporate intermediary which distributes net earnings back to consumer-shareholders. The Pareto inefficient no-trade state,...

In this paper an architecture for a data brokerage service will be proposed. The brokerage service is a part of the system that is being implemented within the European Grid for Solar Observations (EGSO) to provide a high-performance infrastructure for solar applications. A broker interacts with providers and consumers in order to build a profile of both parties. In particular, the broker inter...

Service brokerage is a complex problem. At the design stage the semantic gap between user, device and system requirements must be bridged, and at the operational stage the conflicting objectives of many parties in the value chain must be reconciled. For example why should a user who wants to watch a film need to understand that due to limited battery power the film can only be shown in low reso...

Background Although few studies have explored predictors of congregational vitality (i.e., ministry-oriented strengths, not attendance or growth) and sustainability, inter-organizational relationships matter for organizational wellbeing because their impact on trust, cooperation, information access. However, investigating the relationship between social capital sustainability has previously bee...
