The information systems outsourcing market has seen rapid growth. Companies are increasingly choosing to outsource many of their information systems activities to services firms rather than sourcing them internally. This trend is inconsistent with the predictions of some of the published literature which point to the high costs of using an outside market. These articles, based on transaction co...

Before signing electronic contracts, a rational agent should estimate the expected utilities of these contracts and calculate the violation risks related to them. In order to perform such pre-signing procedures, this agent has to be capable of computing a policy taking into account the norms and sanctions in the contracts. In relation to this, the contribution of this work is threefold. First, ...

In the past decade, we have seen significant increase in the level of outsourcing in many industries. This increase in the level of outsourcing increases the importance of implementing effective contracts in supply chains. In this thesis, we study several issues in supply chain contracts. In the first part of the thesis, we study the impact of effort in a supply chain with multiple retailers. T...

This article deals with IT outsourcing contracts. Contract amendments are often necessary, either because of changing client needs, or because the contracts themselves are incomplete. In some cases, requests for changes give rise to disputes and even litigation. Also market conformity is a hot topic for IT outsourcing contracts. Dissatisfied clients may wish to repatriate the service as a resul...

The emerging B2B technologies allow for more automated management of e-contracts including contract drafting, negotiation and monitoring. As technology infrastructure becomes available for electronic exchange of contracts and contract-related messages, the IT community is becoming more interested in modeling of contracts as governance structures for many interorganisational interactions. This p...

The eCommerce domain needs more and more automation, speed and security for its customers. That’s why the number of B2B applications handling electronic contracts and digital signatures is still increasing. These ones are based on certificates and use secure communication protocols. Nevertheless most of them don’t take into account negotiation regarding to contracts clauses and arbitration of p...

Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway transportation develops increasingly ...

The hedging of weather risks has become extremely relevant in recent years, promoting the diffusion of weather derivative contracts. The pricing of such contracts require the development of appropriate models for the prediction of the underlying weather variables. Within this framework, we present a modification of the double long memory ARFIMA-FIGARCH model introducing time-varying memory coef...
