In the paper a new approach to data representation and manipulation is described, which is called the concept-oriented data model (CODM). It is supposed that items represent data units, which are stored in concepts. A concept is a combination of superconcepts, which determine the concept's dimensionality or properties. An item is a combination of superitems taken by one from all the superconcep...

The psychometric properties of the Italian version of the Coping Inventory for Stressful Situations-Short Version (CISS-SV-21 items) were tested. In a group of 1,291 hospital-based nurses (77.8% women), four alternative factor models of the CISS-SV were tested using confirmatory factor analysis (CFA). The four models were: M1, the original CISS-SV-21 items three-factor model corresponding to th...

People differ in their sleep-wake behavior. This individual difference is conceptualized in different aspects, such as wake up times, bed times, times of peak performance, as well as in morning affect. A total of 14,987 visitors of an exhibition in the LWL State Museum of Natural History, Münster (Germany), did the survey on chronotype and gave their consent that these data can be used for a sc...

this study investigated the utility of all of the above (aota) as a test option in multiple-choice items. it aimed at estimating item fit, item difficulty, item discrimination, and guess factor of such a choice. five reading passages of the key english test (ket, 2010) were adapted. the test was reconstructed in 2 parallel forms: test 1 did not include the abovementioned alternative, whereas te...

Object-oriented expand on the idea of using data structures like struct and union in order to organise logically connected data items. Instead of just associating values in logical groups, as done with structs, object-oriented programming also associates operations to these data item groups. The paradigm requires that all data items modelling the same object need to be categorised in the same c...

Scientific and business communities present unprecedented requirements on provenance, where the provenance of some data item is the process that led to that data item. Previous work has conceived a computer-based representation of past executions for determining provenance, termed process documentation, and has developed a protocol, PReP, to record process documentation in service oriented arch...
