The fundamental study focuses on estimating the volatility of exchange rate returns between the US dollar and African emerging currencies based on GAS-GARCH-student t model. Moreover, we employ the GAS-GARCH-student-t to update the time-varying parameter using the scaled score function of the likelihood function. Empirically, the paper utilises daily exchange rate data between the US dollar and three African emerging currencies (Egyptian Pound, Nigerian Naira, and South African Rand)...

Adolescence and youth are the periods for great opportunity and hope in human life.They are the periods between childhood and adulthood where by the young people are expected to undergo major physical, emotional, and social developments, with significant impact on their sexual and reproductive health.This study was aimed at assessing the magnitude and factors associated with risky sexual behaviours (RSB) among in-school youth (15)(16)(17)(18)(19)(20)(21)(22)(23)(24) in Lalibela Town,...

Mixed crop–livestock systems play an important role in global food production and livelihood provision of millions of rural households. Climate change is projected to alter the functioning and productivity of these systems. Although for many regions the impact of climate change is projected to be large, many uncertainties persist, in particular with respect to impacts on livestock and grazing components, whole-farm dynamics and heterogeneous farm populations. Using an integrated modelling...

An article published in Beirut in 1883 sheds important light on this. External impulses were important, but much of the develop- ment effort was indigenous. There were significant differences in the level of education between towns and the countryside, between regions, and between religious sects. Mount Lebanon is traditionally...

Drought stress strongly affects soil biota and impairs crop production, which under climate change will be exacerbated in semi-arid cropping regions such as the Sahel.Hence soil management systems are needed that can buffer against drought.In West Africa, field studies have found intercropping of millet with the native shrub Piliostigma reticulatum improves soil-plant-water relations, microbial activity and diversity, and suppress parasitic nematodes, which can significantly increase crop...

The scale and the speed of Chinese expansion in Africa are unprecedented in Africa’s modern history. In less than fifteen years, China has become one of Africa’s main trading and financial partners: for example, trade between China and Africa jumped nearly sixfold between 1999 and 2004 and there are more than 800 Chinese businesses operating across Africa (Karen, 2008) with investment of more than $US1.25 billion (Naidu, 2007).
