The conflict situations that have afflicted parts of Kenya every five years, in the wake of general elections, since 1992 were most prominent after the disputed presidential elections of 2007. The magnitude of the clashes, loss of life, destruction of property and internal displacement of people were hitherto unwitnessed. The situation of Orphans and Vulnerable Children (OVC) in Kenya has continued to be of national and international concern. The 2007/2008 post-election violence exacerbated the dire situation of OVC in Kenya. United Nations Children’s Fund (UNICEF) estimated the number of children displaced by the 2007/2008 post-election violence (PEV) in Kenya at 100,000 and those orphaned at 300,000 high. Some of the OVC lost both parents during the violence. Many more were born during and after displacement, and have no knowledge of their homes or origin. They do not understand or even remember the circumstances that caused their parents to be displaced. A survey by UNICEF in 201...

Astronomical spectroscopy has recently expanded into the near-infrared (nIR) wavelength region, raising the demands on atomic transition data. The interpretation of the observed spectra largely relies on theoretical results, and progress towards the production of accurate theoretical data must continuously be made. Spectrum calculations that target multiple atomic states at the same time are by no means trivial. Further, numerous atomic systems involve Rydberg series, which are associated with additional difficulties. In this work, we demonstrate how the challenges in the computations of Rydberg series can be handled in large-scale multiconfiguration Dirac–Hartree–Fock (MCDHF) and relativistic configuration interaction (RCI) calculations. By paying special attention to the construction of the radial orbital basis that builds the atomic state functions, transition data that are weakly sensitive to the choice of gauge can be obtained. Additionally, we show that the Babushkin gauge sho...
