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)

A large and important part of social relations is gender relations between men and women. Over time, the manifestation of such relations has often been one of violence, particularly violence against women. Different approaches have been deployed to deal with the experience of gender-based violence (GBV). One popular approach is the human rights framework that suggest that GBV can be addressed by granting certain rights to women. We argue that while a human rights framework holds some promise in resolving GBV, (...) it is limited in some ways because it does not take the cultural perceptions of gender relations that envision gender duties into account. As part of our argument, we show that social relations in African communities ought to be primarily based on the principle of duty to the other, rather than an emphasis on rights. We conclude that there is a need to complement the rights-based approach with a duty-based approach to effectively address GBV. (shrink)

The paper discusses the notion of authentic motherhood within the frame work of the traditional Yoruba-African society. It argues that an authentic mother, according to the traditional Yoruba-African understanding, is one who performs all her responsibilities as stipulated by the norms and precepts of society. It also points out that the responsibilities of an authentic mother are holistic in nature and when wholesomely fulfilled, have prudential, egoistic, and utilitarian justifications. The paper further provides a philosophical comparison of motherhood in Yoruba-African (...) and in Western understanding. The paper tries to establish that the Yoruba qualities of motherhood are essential to being a good mother no matter where in the world one lives, and irrespective of the culture one belongs to. It concludes that the Yoruba notion of authentic motherhood is relevant to the process of social reconstruction in the contemporary world. (shrink)

Developing countries are endeavoring to advance into the 21st century information age. Their progress, however, is hamstrung by the dire lack of trained, skilled and knowledgeable IS workers who are able to interact with online and off‐line information sources. These countries can tap from the rich intellectual capital lying dormant within the ranks of disabled people to boost the pool of IS workers in their societies. However, before developing countries can draw on the information systems capabilities of disabled workers, these (...) workers themselves must be able to function at par with their able‐bodied counterparts as information workers. This presupposes the availability of special‐purpose information systems devices and approaches developed for disabled users. In this paper, therefore, we examine several issues that are pertinent to IS and disabled people in developing countries, and propose an integrated infrastructure to enhance the interaction of disabled people with on‐line information sources. The study includes issues related to the suitability of different interaction methodologies and technologies for people with disabilities. Additionally, we propose the design of customized interfaces that can be used by disabled people to develop Web‐based database applications and to access and query on‐line databases. (shrink)

In a Guest Lecture delivered by Professor Thaddeus Metz at a Colloquium organized in honour of my 50th birthday, he critically interrogated various aspects of my African philosophical scholarship with a particular focus on what I consider as the task of an African philosopher in the twenty-first century. Drawing on the existential and social problems in contemporary Africa, I have argued that African philosophy should be tailored towards ameliorating these problems as a way of making life meaningful. Metz’s striking criticism (...) is that doing philosophy that does not necessary address existential and socio-political problems in Africa is worth taking seriously in African philosophy. He adds that the very idea of “meaningfulness constitutes a strong, competing reason,” to do philosophy for its own sake. In this article, I reply Metz, contending that his critique only differs in degree from the position I earlier defended but not in kind regarding the connection between theory and praxis. While we both agree on the imperativeness of theorizing in African philosophy, I argue further that African philosophy should go beyond this to solve the practical issues relevant to the advancement of humanity and the society. Keywords: African Philosophy, theory, Praxis, Thaddeus Metz. (shrink)

The flurry of debate that trailed the existence of African philosophy in the 1960s and 70s and the consequent demise of the controversies in the late 1990s have occasioned a periodiszation shift from traditional African philosophy to contemporary African philosophy. While the scope and nature of predominant issues inthese periods differ considerably, what ought to constitute the basis and shape the direction of discourse in contemporary African philosophy remain controversial. In this regard, this paper argues that rethinking African philosophy should (...) be high on the agenda. It harps that more fundamental to contemporary African philosophy, is the critical need for self-assessment and re-evaluation, which would involve rethinking the nature, direction, scope, method and place of African philosophy. Rethinking African philosophy is a cognitive process of charting a new course of pragmatic reflection on metaphysical, epistemological, ethical, aesthetical, social and political themes in contemporary African philosophy, in order to make relevant philosophical abstraction to practical human problems inthe continent. The case is justifiably made that those African philosophers should make the influence of their speculations spill beyond the confine of academic citadel to the outside world such that will influence the lives of contemporary Africans.

This article is devoted to the problem of interpretation and understanding of African philosophy as a phenomenon of intercultural communication. It is a question of the presence of stereotypes in perception and assessments of African philosophy: from the assertion of its interiority and non-philosophical character to the propaganda of its primacy in the whole of world philosophy as the theorized core of spiritual life. The author also indentified the significant obstacle in the study of African philosophy and understanding of its (...) status in the history of world philosophy. Also the article touched the importance of African revival, and the key factors to its revival, the idea of Afrocentrism was also been mentioned as the key solution for the African revival. In this work, ethnophilosophy is further considered as the source of the whole philosophy of Africa. Attention is also paid to the problem of misunderstanding and misinterpretation of African philosophy and culture in the framework of world or universal philosophy and science. Also in the article, issue of searching for African identity is being raised, the ideas and impacts of some African thinkers, also socio-political concepts such as Pan-Africanism, Negritude, African socialism, African humanism, Afrocentrism and others, which had a serious impact on African socio-political life were also identified. The diversity of ethnic cultures, and its roles in the black continent were mentioned, and as well, emphasis on ethical issues, religions representations and superstitions. (shrink)

This paper compares the educational thoughts of Obafemi Awolowo and Tai Solarin. Its methodology is critical and comparative. The paper argues that the variations of the political philosophies of the two thinkers account for the differences in their views on education. It further contends that the educational ideas of both thinkers reflect African cultural experiences. The paper also explores the possibility of integrating the insights of the two thinkers into the educational policies and practices of contemporary African societies.

This paper posits that there are elements of oppression in some of the Yoruba proverbs that relate to women. It argues that these proverbs violate the rights and dignity of women, and that they are indicators of discrimination against women in Yoruba culture. The paper further argues that the most fundamental but neglected aspect in gender discourse lies in the proverbial resources of the community. The paper provides textual evidence of proverbial oppression of the feminine gender in Yoruba culture, and (...) also underscores their pernicious effects on the struggle for gender balance. The paper contends that there is an urgent need to review the assumptions underlying these proverbs. (shrink)

This study examines the link between social media networks and democratization process by focusing on the 2015 General Electionsin Nigeria. Relying on Manuel Castells’ network theory and empirical fieldsurvey, the paper investigates the prevalent conditions that have nurtured SMNsparticipation in Nigeria’s democratic space and the challenges and prospects ofsocial media as catalysts for deepening democracy in the country. The paperasserts that although social media remains veritable tools for democraticconsolidation worldwide, the salience and impact are still at the nascentstage in Nigeria. (...) Besides, institutional and legal impediments, economic andinfrastructural challenges have contrived to limit the envisaged positive impactof SMNs in the democratization process in Nigeria. The paper recommendsefforts to stimulate Internet penetration and social media affordance while theNigerian cyberspace should be more democratised. (shrink)

Genetically modified cassava is currently being developed to address problems of diseases that threaten the food security of farmers in developing countries. The technologies are aimed at smallholder farmers, in hopes of reducing the vulnerability of cassava production to these diseases. In this paper we examine barriers to farmers’ voice in the development of GM cassava. We also examine the role of a translational research process to enhance farmers’ voice, to understand the sources of vulnerability farmers in a group in (...) Kenya’s Coast face, and to determine if their concerns are consistent with those of the scientists in agriculture addressing farmers’ needs. A two-way communication participatory process provided insights into the complex vulnerability context of farmers, their primary concerns with processing and markets of cassava in order to improve livelihoods, the lack of networks with two way communication flows, and the lack of information on GM technologies. The translational research engaged farmers and scientists in an iterative process where scientists are learning what farmers need, and farmers are learning about the potential benefits and risks from GM technologies, while at the same time expressing their concerns.

Nigeria agriculture, food security and dietary intake have not been exempted from the disruptions in countless sectors around the world due to the outbreak of COVID-19. The country first experienced the outbreak on February 27, 2020, and the experience since then has shown negative effects not only on the socioeconomic conditions but also on agriculture, food security and dietary intake. Long term in-depth analysis of the effects of this pandemic on food security and dietary intake using quantitative data is still (...) very difficult due to paucity of data and the great level of the improbability of the trajectory of the spread of the Virus. This study is a rapid assessment of the short and long-term potential effects of the disease. It relied on a review of situation reports especially by the Nigeria Centre of Disease Control and other reports around the world on COVID-19, personal observations, and public opinion via mobile telephone survey of Lagos and Oyo States, Nigeria. Findings show that food demand and supply shocks caused by COVID-19 outbreak affect agriculture, food and dietary intake negatively through COVID-19 policies. It leads to a reduction in household income coupled with hike in food prices. Owing to the Nigeria’s crude farming practice, there was a scarcity of hired labour required for production process during 2020 farming season. This implies a high likelihood of low output and further surge in food prices in the future. Food access was also compromised with the accumulation of unsold fresh produce by the smallholder farmers and the low salary earners during movement restrictions and of loss income as a result of international border closure. Food and dietary intake is affected as people are shifting diets to more affordable and low quality foods, while food stability is not guaranteed due to market insecurity, prompting an extraordinary level of indecision. The study concludes that the shock of COVID-19 is not only a demand management problem but a multidimensional crisis requiring monetary, fiscal, and health policy responses with global collaboration and cooperation.

Since the Farnesianus emerged in the 15th century, a passage where Festus sets himself against his predecessor Verrius Flaccus has been interpreted in four different ways. These are discussed and an emendation proposed that does not depend on any of them but has a consequence for what Festus published.

Publicada en 1979, Violence se desarrolla en la ciudad nigeriana de Benín, durante el boom petrolífero de la década de 1970. La narrativa se centra en dos matrimonios que representan ambos extremos del espectro social, cuyos caminos se cruzan mientras sortean diversos obstáculos. La novela de Iyayi constituye una crítica marxista de la violencia ejercida por la pobreza y la desigualdad extrema. Violence muestra cómo ciertos cuerpos humanos se cosifican y explotan de manera sistemática, a la vez que aquellos que (...) no generan ganancias son descartados sin el menor rastro de humanidad. Desde la perspectiva de la ecocrítica urbana, este artículo examina instancias de cosificación corporal en la novela y, específicamente, de comoditización de energía y materia humanas entendidas como recursos naturales. El estudio propone que Iyayi no solo critica esta comoditización al presentarla como una consecuencia del proyecto capitalista, sino que también la cuestiona mediante actos de cuidado resistente que devuelven a los cuerpos cosificados su calidad de sujeto. Estos actos de cuidado constituyen una forma de refutar la separación artificial de Naturaleza y Sociedad, contenida en el dualismo de cuerpo y mente, que históricamente ha justificado la explotación y expropiación capitalista (neo)colonial. El presente artículo contribuye entonces tanto al campo de los estudios poscoloniales como a los de ecocrítica urbana y literaturas africanas, centrándose en una obra relativamente poco analizada y en problemáticas sumamente relevantes para la Nigeria contemporánea.

In Italy, at the end of the tenth century, a pedant named Regulus (?) who had a copy of the De Verborum Significatu (or had made extracts from one), wishing to read Plautus (so often quoted by Festus), took the opportunity of an illness to appeal to certain prelates whose church-library contained a MS. of the comedian. Through their stupidity he received not Plautus, but Plato, i.e. Chalcidius' translation of the Timaeus. Disappointed, but not deterred, he wrote the following (...) letter (in a sort of rhyming prose, affected by the litterati of that time) on the fly-leaf and returned the MS. (now Bamberg. Class. 18), hoping that by much repetition he might hammer into their dull heads the difference between PL-AU-TUS and PL-A-TO and yet save them from chagrin and resentment (the material for the letter was supplied by Festus, although the opening illustration comes from Chalcidius).

In a day in which there are different religious system vying for acceptance and probably even dominance, it is high time to identify a peaceful model for inter-religious understanding and communication. St. Paul had several interactions with the Jewish leaders, monarchs and government officials on religious topics and issues in between A.D. 60 to A.D 62 at Caesarea. His interaction with King Agrippa II and Governor Festus can be used as a paradigm for contemporary inter-religious understanding and communication. Even (...) though Paul’s life was hanging on a balance as a prisoner about to be transported to Rome, he did not resort to violence, verbal abuse or rain down curses, when his religious claims were questioned. Instead, he argued as a seasoned philosopher, prayed as a pious saint and appealed as a prisoner in chains with humility for the ‘veracity and the reasonability’ of his truth claim. The article will interact with few philosophical themes that surface during this discourse and dialogue and also attempt to trace St Paul’s use of rhetoric in his discourse. The title of this article is ‘St. Paul’s discourse and dialogue with King Agrippa and Governor Festus as a model for contemporary inter-religious understanding and communication’. The primary source for this article is the book of Acts in the New Testament and the secondary source would be dictionaries and books. (shrink)

In the Phillipps Library at Cheltenham there is a MS. of the Epitome which Professor Thewrewk was unable to use for his edition. No one who knows the difficulties which attend the study of MSS. in this Library will blame him for the omission. The Phillippsianus has the form usual in codices of the Epitome , a quarto volume with two columns to the page, and with each article occupying a separate paragraph and beginning with a fairly large initial letter. (...) It was written by Ellinger , during his previous stay at Altaich, as is shown by the subscription in capital letters which stands at the end of the whole volume, : Abbas indignus ego Ellinger peccator istam glosam scripsi dum essem in Altahensi monasterio Deo sanctoque Quirino. Rogo vos omnes in ea legentes ut oretis pro me. (shrink)
