    Guinea worm disease and its persistence in some rural communities in Nigeria
    (2007) Morenikeji, O. A.; Alade, A. O.; Odaibo, A. B.
    Studies were carried out in six villages of Ogun State, Nigeria from January to December 2004 to identify the reasons for the persistence of guinea worm disease in spite of eradication measures. Pre-tested structured questionnaires were administered to 250 head of households in the endemic villages to assess their knowledge attitude and practice (KAP) in the management of guinea worm disease. The overall prevalence of infection for the study-period was 1.0%. 96.0% of the respondents depended solely on ponds for drinking water during the dry season. 80.0% of the respondents had been infected before 68.0% think that the disease is caused by spiritual attack, while 4.0% associated the disease to drinking bad water. 77.5% did not know if it is possible to prevent the disease. It was observed that immigrant farm labourers and apathy on the part of eradication officials may play vital roles in the transmission of the disease in the area. This study shows that there is need to ascertain and specifically address reasons for the persistence of the disease in areas still endemic.

    Volatility persistence and returns spillovers between oil and gold Prices: analysis before and after the global financial crisis
    (Elsevier Ltd, 2016) Yaya, O. S.; Tumala, M. T.; Udomboso, C. G.
    This paper investigated volatility persistence and returns spillovers between oil and gold markets using daily historical data from 1986 to 2015 partitioned into periods before the global crisis and after the crisis. The log-returns, absolute and squared log-returns series of these asset prices were used as proxy variables to investigate volatility persistence using the fractional persistence approach. The Constant Conditional Correlation (CCC) modelling framework was applied to investigate the spill over effects between the asset returns. The volatility in the gold market was found t be less than that at the oil market before and after the crisis periods. The returns spill over effect was bid irectional before the crisis period while it was unidirectional from gold to oil market after the crisis. The fact that there was no returns spill over running from oil to gold after the crisis suggested a measure of optimumal location weights and hedge ratio. The results obtained are of practical implications for port folio managers and decision managers in these two ways: gold market should be used as a hedge against oil price inflationary shocks; and the volatility at the oil market can be used to determine the behaviour of gold market.
