Two major problems in schema integration are to identify correspondences between different conceptual schemas and to verify that the proposed correspondences are consistent with the semantics of the schemas. This problem can only be effectively addressed if the conceptual schema is expressed in a semantically rich modelling formalism. We introduce such a modelling formalism, the distinguishing ...

the goal of this study was to investigate the effect of using computer conceptual maps­, compared with  usual way of drawing them by pencil and paper­, in increasing learning, recalling and educational progress motivation in geology course among high school students. the study was conducted in semi experimental method in which students of 3 classes were classified in 3 groups. (group 1: common ...

Following Blumenthal et al. 1] and Piran et al. 2] I discuss a simple model for the gravitational formation of voids. This model enables us to estimate the primordial perturbation required on the scale of voids. A comparison of this condition with the constraints on the spectrum of uctuations derived from CMBR observations reveals that gravitational growth of large voids require more power on t...

abstraCt An integrative model explaining intentions to use an information technology is proposed. The primary objective is to obtain a clearer picture of how intentions are formed, and draws on previous research such as the technology acceptance model (Davis, Bagozzi, & Warshaw, 1989) and the decomposed theory of planned behavior (Taylor & Todd, 1995a). The conceptual model was tested using que...

The present study explores hemispheric differences in verb and verb-derived noun production in terms of the impact of various picture and word characteristics on visual field reaction time variance. The unique contribution of predictors has been interpreted as activation of a corresponding property, as indication of a stage of picture processing and as activation of a corresponding mechanism/sy...

This article deals with the peculiarities of mechanisms providing formation of semantics of compound words from the perspective of the cognitive approach. More to the point, it is a question of conceptual derivation, where meaning formation of compound words is carried out by the interaction of its component conceptual structures. The author has researched the main means which take part in the ...
