The purpose of this study was to examine the prediction of autonomy support, psychological mediators and self-determined academic motivation on basic competences. A sample of 405 adolescent students aged between 12 and 16 was used to measure autonomy support, psychological needs, self-determined motivation and basic competences. The results supported the factorial structure of the scale and sho...

The size of an ERP project can be a useful measurement for predicting the effort needed to complete an ERP implementation project. Because this measurement does not exist, research is needed to find a set of variables which can define the size of an ERP implementation project. This paper shows 21 logical clusters of ERP implementation project activities as a result of a formal group session. Th...

Separated spherical harmonic analysis coefficients of the external and internal parts of the observed quiet-day geomagnetic field variations (Sq) for the North Central Nigeria were used to determine the conductivity profile to depths of about 873 km by Schmucker equivalent substitute conductor method. Within the crust, the conductivity increased from 0.027 S/m at a depth of 7.4 km to 0.074 S/m ...
