ABSTRACT
The paper begins by positing that African poetry in English expression has produced four generations of poets and then emphasises that the study is focused on the postmodernist generation, which is the latest generation of African poets in English expression. In the postmodernist generation, there are different kinds of poetic practices, but the one that is of interest in the paper is called a new historicist practice. This is explained as having to do with ‘the shifting and contradictory representations’ of ideas, issues or…

This article contends that spirits are perceived in different ways in different cultures. While some spirits are believed to take the form of animals like a horse with wings and a horn on its forehead, or a ram with a horn on its forehead, others are believed to take the form of humans with wings attached to their shoulders. One fascinating thing about these spirit creatures is that, as typical of spirits, they are at liberty to either make themselves visible…

ABSTRACT

This article argues that African literature is a didactic literature. It points out that even though African literature has borrowed so much from European literary culture, especially in the areas of form and language; didacticism is not one of those concepts that African literature inherited from the European literary culture. By didacticism, it is implied that African literature is aimed at correcting, informing and educating its readers. These functions of didacticism are inherent in African oral traditional storytelling and are carried…

ABSTRACT
A common narrative on Africa’s development process is that specific country policies of income growth and redistribution are necessary for poverty reduction. For growth theoreticians, economic growth must be pursued while for political economists, redistribution is necessary to cushion the detrimental effect of reform policies. These views appear to converge in the many policies and programmes implemented over the years by the Nigerian government. In light of this, we accounted for the effect of these variables using two recent national household survey data sets collected…

Malaria is the world's leading parasitic disease and affects approximately 40% of the world's population (ap-proximately 2.4 billion people) in more than 100 countries (1). A life threatening illness arising from malaria infection, usually referred to as severe malaria, may occur in 1 – 2 % of infection (2, 3). Of the five clinically relevant Plasmodium species (Plasmodium falciparum, P. vivax, P. ovale, and P. malariae, P. knowlesi), P. falciparum mainly accounts for severe malaria, an important cause…

All procedures in the diagnostic medical laboratories are not without associated risks. Laboratory personnel handling clinical samples containing highly infectious agents are at a high risk of contracting laboratory-acquired infection. This risk is particularly high for those working in microbiological laboratories [1,2]. Injuries through infected needles and sharp cutting instruments encounteredin diagnostic procedures represent potential sources of laboratory-acquired infections.

This paper interrogates the substantive philosophy of Nigeria’s development policy through attempts at survey of the historicity of planning in Nigeria. The domestication of the interactions of the development phenomena, it contends is riddled with inconsistency of philosophy or ideology and methods in Nigeria. Since it would appear that Nigeria’s planning was mostly based on woolly logic without deep philosophical substantiation, the development progression was stunted and the possible gains of import substitution industrialisation, miscarried.…

The perfunctory characterisation of economic crises has gradually sneaked into academic discourse and increasingly acquiring scholarly influence in Nigeria. This largely features in the analysis of Nigeria’s economic crises. The current crisis is ascribed to the decline in crude oil production and glut in the oil international market. However, the hazy analysis raises questions about the ontology and nature, character and definitive appearance of economic crises. This paper is an attempt at political economy critique…

On-farm research is a set of procedures for adaptive research aimed at developing recommendations for representative groups of farmers. These groups of farmers’ plots are used as the research site, thereby allowing for appropriate site specific technology, valid results and faster adoption. The move towards on-farm research means that researchers, such as plant breeders and agronomists, who have been trained in techniques of on-station research, are now under pressure to move on-farm. As a result of variations between…

The efficient use of plant genetic resources requires the careful collection of germplasm, its conservation, evaluation, documentation and exchange. Over the last few decades, plant tissue culture has been used to propagate hundreds of plant species. The use of this technique has been particularly important for conservation and multiplication of plants that produce seeds, propagated vegetatively, recalcitrant or have unpredictable seed germination. In vitro collection is a natural outgrowth of this work. Tissue culture being a basic component of plant…

Abstract

The global trend for energy consumption as a foundational requirement for economic and social development is an increasing one. Electricity consumption is proportional to the CO2 emitted at the process level and especially for machining processes. The electrical energy demand during machining can be categorized and modelled as basic energy (energy demand by the machine tool while operating

at zero load) and tip energy (energy for actual material removal–cutting). The tool tip energy is evaluated from the specific…
