Sierra Leone suffered from 11 years of civil war (1991-2002) resulting in tens of thousands of deaths and mutilations and massive population displacement. In 2001, ARC International, Sierra Leone, conducted a baseline survey of 244 female youth and 293 male youth on knowledge, attitudes, and behaviours around HIV/AIDS and STIs in Port Loko. In 2003, following 2 years of HIV prevention activities, a comparable post-intervention survey of 250 female and 299 male youth was performed. Comparison of baseline and post-intervention results showed that HIV/AIDS knowledge increased dramatically among both groups, with those able to name three effective means of avoiding AIDS increasing from 4% to 36% among female youth, and 4% to 45% among male youth. Reported condom use at last sex increased among female youth from 16% to 46% and among male youth from 16% to 37%. These results demonstrate that, despite the challenges inherent in a post-conflict country, good quality AIDS prevention programmes can be successful.

In this study, the nexus between the generated oil revenue in Nigeria from 1981 to 2021 and its possible influences on the relative growth of the economy on a sustainable basis has been investigated. Utilizing the Johansen Co-Integration test, Granger Causality Technique as well as the Error Corrections Mechanism (ECM) to analyze the sourced data from both the World Development Indicators and the Nigeria Centra Bank. The findings depict the occurrence of a long-run connection amongst the variables of the study as both the eigenvalue test and trace test depict two and three cointegrating equations respectively at a 5% level of significance. 34.8% of short-run errors are rectified annually, according to the error correction mechanism. As a result, the coefficient reflects the rate of adjustment at which the RGDP's short and long runs are tied together. Further findings reveal that economic growth (RGDP) granger caused oil revenue (OREV) and that the generated oil revenue in Nigeria (OREV) granger caused economic growth (RGDP) during the study period. This suggests that the generated oil revenue in Nigeria (OREV) and economic growth (RGDP) relationship is causally bidirectional. This study, therefore, recommends the creation and efficient implementation of policies that facilitate prudent identification, collection and utilization of the generated oil income and adequate deployment to critical underdeveloped and developing sectors of the economy.
