Change operators are the building blocks of ontology evolution. Different layers of change operators have been suggested. In this paper, we present a novel approach to deal with ontology evolution, in particular, change representation as a pattern-based layered operator framework. As a result of an empirical study, we identify four different levels of change operators based on the granularity, ...

Increasingly, theorists have suggested that social competence is an evaluative construct that will vary as a function of who is judging behavior. This study examined how two key groups in children’s social environments—peers (N = 663, age range = 10.83–15.25 years) and teachers (N = 49)—rated the effectiveness of different behaviors generated by youth in response to physical, verbal, and relati...

Implementation and maintenance of interorganizational systems (IOS) require investments by all the participating firms. Compared with intraorganizational systems, however, there are additional uncertainties and risks. This is because the benefits of IOS investment depend not only on a firm’s own decisions, but also on those of its business partners. Without appropriate levels of investment by a...

The NREFS project is re-evaluating the management of radiation accidents, paying attention to environmental, financial and safety issues and to the threat and response phase. In designing our project some two years ago, we were concerned to avoid any assumption that a future accident will be similar to a past accident, in particular the Chernobyl and Fukushima Accidents. After a year of researc...

Threshold-based fall detection has been widely adopted in conventional fall detection systems. In this paper, we argue that a fixed threshold is not flexible enough for different people. By exploiting the personalised and adaptive threshold, we propose a novel threshold extraction model, which meets being adaptive to detect a fall, while only taking consideration of data from activity of daily ...

Automatic image description systems are commonly trained and evaluated on large image description datasets. Recently, researchers have started to collect such datasets for languages other than English. An unexplored question is how different these datasets are from English and, if there are any differences, what causes them to differ. This paper provides a crosslinguistic comparison of Dutch, E...

Purpose: To develop an adaptable gene-based vector that will confer immune cell specificity to various
