This paper is a historical analysis of the contributions of music artistes to the idea of development in Africa in the period between 1974 and 1987. Itseeks to show that concern for the development of the continent was not confined to the intellectual community. Music artistes were not merely interested in entertainment; they also paid attention to the real problems that confronted the society of their time, thereby sharing in the concern of political thinkers of all ages. The works of (...) three artistes - Sonny Okosun, Fela Anikulapo-Kuti and Bob Marley - are selected for detailed examination, although references are made to other artistes. The study depended on primary and secondary source material. The paper is a contribution to knowledge in the field of African Political Thought. (shrink)

Globally, women have more access to positions of authority and participate more in decision-making, regardless of context and rank, than a few years back. This is because of on-going global campaigns supported by various national and international laws and declarations. Increasingly, women have been exercising their rights and obligations to actively participate in politics and become visible in governance. Within Nigerian society, the efforts of women in governance, especially in the pre-colonial era, cannot be overlooked. Over the years, women in (...) Nigeria have moved from the back seat to the roles of bread-winners, decision-makers and leaders of their immediate families. Irrespective of these progressive developments, women's contributions to national development still have minor impact on decisions that affect society as a whole, due to the perceived marginalization which still holds strong in most developing countries like Nigeria. Cultural and social norms, glass ceiling effects, and other exclusionary factors continue to dictate relegation of the presence and voice of women to a lower rank in public life. Against this background, this paper attempts to shed light on the role of civil organizations in enhancing women's participation in politics and decision-making in governance issues in Nigeria. The paper examines strategies employed by a Muslim women civil organization in contributing to the decision-making that affect women generally in the society, and possible challenges facing women active participation in this political era. Using documented researched materials, the findings of the study show that women's intellectual, and political capabilities irrespective of the religious background, are vital components of every society.

This paper is concerned with the formulation and analysis of an epidemic model of COVID-19 governed by an eight-dimensional system of ordinary differential equations, by taking into account the first dose and the second dose of vaccinated individuals in the population. The developed model is analyzed and the threshold quantity known as the control reproduction number R0\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\mathcal {R}_{0}$$\end{document} is obtained. We investigate the equilibrium stability of the system, and the COVID-free equilibrium (...) is said to be locally asymptotically stable when the control reproduction number is less than unity, and unstable otherwise. Using the least-squares method, the model is calibrated based on the cumulative number of COVID-19 reported cases and available information about the mass vaccine administration in Malaysia between the 24th of February 2021 and February 2022. Following the model fitting and estimation of the parameter values, a global sensitivity analysis was performed by using the Partial Rank Correlation Coefficient (PRCC) to determine the most influential parameters on the threshold quantities. The result shows that the effective transmission rate (α)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\alpha )$$\end{document}, the rate of first vaccine dose (ϕ)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\phi )$$\end{document}, the second dose vaccination rate (σ)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\sigma )$$\end{document} and the recovery rate due to the second dose of vaccination (η)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\eta )$$\end{document} are the most influential of all the model parameters. We further investigate the impact of these parameters by performing a numerical simulation on the developed COVID-19 model. The result of the study shows that adhering to the preventive measures has a huge impact on reducing the spread of the disease in the population. Particularly, an increase in both the first and second dose vaccination rates reduces the number of infected individuals, thus reducing the disease burden in the population. (shrink)
