With the growing utility of blockchain technology, desire for reciprocal interactions among different blockchains is growing. However, most operational networks currently operate in a standalone setting. This fragmentation form isolated creates interoperability difficulties, inhibiting adoption various ecosystems. Interoperability key factor healthcare domain sharing EHRs patients registered in...

We review traits of reusable clinical data and offer a typology of clinical repositories with a range of known examples. Sources of clinical data suitable for research can be classified into types reflecting the data's institutional origin, original purpose, level of integration and governance. Primary data nearly always come from research studies and electronic medical records. Registries coll...

Two major problems in constructing data federations (for example, data warehouses and database federations) concern achieving and maintaining consistency and a uniform representation of the data on the global level of the federation. The first step in creating uniform representations of data is known as data extraction, whereas data reconciliation is concerned with resolving data inconsistencie...

The generality, autonomy, and mobility of autonomous objects open up new possibilities for supporting a broad range of requirements of federates and federations under the High Level Architecture (HLA). Their generality allows them to execute arbitrarily complex behaviors in heterogeneous environments without modification while their autonomy and mobility allow them to arrive at solutions collec...

Web services are expected to become the foundation of highly-dynamic distributed business computing architectures. By building upon the Internet-based technologies that changed the face of business computing over the last decade, web services are a significant step towards a truly universal infrastructure for e-business. Focusing on the case of opportunistic virtual enterprises, this paper firs...

The goal of HLA Data Distribution Management (DDM) services is to limit the messages received by federates in large distributed federations to those messages of interest in order to reduce (1) the data set required to be processed by the receiving federate and (2) the message traffic over the network. If this functionality is provided in a manner that is efficient, it can significantly improve ...

The present study aimed to evaluate the psychometric properties of the Managerial Behaviour Instrument, Portuguese version, for the Brazilian sport federations. The sample was composed of 263 members of federations, including managerial (39.5%), technical (35.1%), executive (20.6%) bodies and others (4.9%). The study used descriptive, reliability and confirm-atory factor analyses. Values of int...
