Service interaction manifest itself as an unexpected behaviour of multiple services used together either simultaneously or in sequence. The paper describes a policy based approach to web service interaction management. Parlay X web services for call control, mobility, user interaction and policy management are studied. Web service behaviour is described as a set of policy rules. Rules are gener...

METHODS All cases diagnosed with OM between January 2007 and December 2010 were retrospectively reviewed. The variables examined include epidemiological characteristics, risk factors, affected bone, radiographic changes, histology, microbiological culture resu...

Electronic markets and especially online auctions gain more and more importance and a plethora of market mechanisms is emerging on the Internet. The great variety of trading rules hinders agents easily switching between different marketplaces and, therefore, fragments the overall market – supply and demand might fail to meet due to agents’ inability to interact with the same market mechanism. T...

This paper examines the influence of communication form on employee uncertainty during mergers and acquisitions (M&As). Specifically, the author uses narrative theory to analyze how narrative organizational communication affects the three components of uncertainty – decreased predictive, explanatory, and descriptive ability. It is hypothesized that employees whose organizations use narrative M&...

We continue with the task of obtaining a unifying view of process semantics by considering in this case the logical characterization of the semantics. We start by considering the classic linear timebranching time spectrum developed by R.J. van Glabbeek. He provided a logical characterization of most of the semantics in his spectrum but, without following a unique pattern. In this paper, we pres...

This paper studies the descriptional complexity of multi-parallel grammars with respect to the number of nonterminals and selectors, and the length of these selectors. As a result, it proves that every recursively enumerable language is generated by a multi-parallel grammar with no more than seven nonterminals and four selectors of length five.

Descriptive studies often represent the first scientific toe in the water in new areas of Inquiry. A fundamental element of descriptive reporting is a clear, specific, and measurable definition of the disease or condition in question. Uke newspapers, good descriptive reporting answers the five basic W questions: who, what, why, when, where ••• and a sixth: so what? Case reports, case-series rep...
