The MPEG-21 Media Contract Ontology (MCO), a part of the standard ISO/IEC 21000, is an ontology to represent contracts dealing with rights on multimedia assets and intellectual property protected content in general. A core model provides the elements to describe the permissions, obligations and prohibitions exchanged in the clauses of a contract. Specific vocabulary is defined in a model extens...

This paper addresses the problem of ensuring compliance of business processes, implemented within and across organisational boundaries, with the constraints stated in related business contracts. In order to deal with the complexity of this problem we propose two solutions that allow for a systematic and increasingly automated support for addressing two specific compliance issues. One solution p...

Bad smells are usually related to program source code, arising from bad design and programming practices. Refactoring activities are often motivated by the detection of bad smells. With the increasing adoption of Design-by-Contract (DBC) methodologies in formal software development, evidence of bad design practices can similarly be found in programs that combine actual production code with inte...

INTRODUCTION In England, in 2006, new dental contracts devolved commissioning of dental services locally to Primary Care Trusts to meet the needs of their local population. The new national General Dental Services contracts (nGDS) were based on payment for Units of Dental Activity (UDAs) awarded in three treatment bands based on complexity of care. Recently, contract currency in UK dentistry is...

in this article, we tried to identify mechanisms of technology transfer and their legal basis in buy-back contracts. then, analyze the effect of wto regulations on those contracts. in addition, answer these questions: what are legal mechanisms of technology transfer in buy-back contracts? what are the effects of acceptance of wto rules on technology transfer policies in buy-back contracts and t...

We develop a model of nonstationary relational contracts in order to study internal wage dynamics. Workers are heterogeneous and each worker’s ability is both private information and fixed for all time. Learning therefore occurs within employment relationships. The inferences, however, are confounded by moral hazard: the distribution of output is determined by both the worker’s type and by his ...

Using term structure data of Credit Default Swap (CDS) spreads for the four Japanese mega-banks and the government, we jointly estimate the default intensity and expected recovery (loss) given a default. In doing so, we attempt to further identify the difference in the expected recovery ratios between senior and subordinated CDS contracts. Estimation results are summarized as follows. (i) The d...
