GPRS Function Test using TTCN

Functional and conformance testing of new standardized services and protocols is a challenging task as standards may change during implementation and the test system has to be adapted to the system under test continuously. This paper describes how modular and concurrent TTCN was deployed for validation of the GPRS support nodes and reports on the experience collected

Sociometric characteristics of classes integrating children with mild intellectual disabilities

The aim of our study was to explore the sociometric characteristics of primary school classroom communities integrating children with mild intellectual disabilities (MID). Data was collected with a self-developed paper and pencil peer nomination instrument that consisted of 28 items including questions concerning sympathy, community functions, individual abilities, popularity and integrational difficulties. Sociometric indices of 86 classes in grades 4, 5, and 6 were analysed. Results show that in general the communities seemed to be cohesive, with an average of 1 tie per person. 59% of MID students had a reciprocated tie, still they were regarded as having problems with social integration and needing support. Our results confirm that class size is of crucial importance for the success of integration, though it is not evident if smaller class size is always more favourable. The study also highlights those sociometric indices that require attention from teachers in bigger or smaller classroom communities
