Effective management and change in Africa
Sudanese academic and research institutions have long suffered from varying degrees of mismanagement, poor management and inappropriate management. This paper will attempt to explore a number of issues about Human Resource Management (HRM) within the Sudanese academic and research institutions, namely the University of Gezira (GU) and the Agricultural Research Corporation (ARC). Before that happens, it is necessary to engage in a little background study, as an understanding of HRM in these institutions can be possible only in the context of understanding HRM and Sudan. Therefore the early parts of this paper will deal with the context and activities of HRM that are applicable to both Sudan and Africa. In particular there will be a focus on the practice and challenges of HRM within ARC and GU as well as a reconceptualisation of our understanding of HRM in Sudan.
Technology management in the Sudan: strategic and policy challenges
This paper addresses the strategic and policy challenges facing technological transformation and productivity increase in the Sudan. It examines the various factors which influence agricultural technology adoption decisions as well as the constraints facing the agricultural sector in the Sudan. The paper also demonstrates that complexity and linkages of the various technology adoption factors represent real challenges in future technology management in the Sudan. Finally, a number of findings emerge which outline the key issues relating to the effective management of technological transformation in the Sudan and other similar African countries.
Anomalous Annealing Behavior of Arsenic Implanted Silicon as a Function of Dose and Energy
Anomalous annealing behavior of damage in As implanted Si has been investigated by channeling effect measurements. Room temperature As implants with doses from 1014 to 2 × 1016cm-2 at energies ranging from 50 to 250 keV into Si were annealed over the range of 600°C to 1100°C. Anneal temperatures ≥ 950°C reduce the disorder for ion doses of 0.5 to 1 × 1016 cm-2 at energies between 50 and 250 keV. Anomalously high residual disorder was found for the intermediate doses of 2 × 1014 to 2 × 10/cm2 implanted above 100 keV. For this intermediate dose, annealing of implants performed at liquid nitrogen temperatures did not show significant reduction in this damage. However implants at 200° to 300°C indicate a lower amount of damage compared to the room temperature implants.
