The 1979 Nigerian elections reflected the dedication of Nigerians to pursue democratic governance and the severe challenges to be overcome. The sweeping victory of the NPN, and the election of Alhaji Shehu Shagari as president, required a last-minute manipulation of the formula for achieving victory in the first round. After...
In the years preceding the 1979 national elections, ideology featured prominently in political debates and consultations regarding the new constitutional order. Proponents of a social democratic system were particularly prominent. However, the actual formation of political parties, governed by the new requirements for national representation, and the resurgence of veteran...
A half-century of high revenues from petroleum export has failed to elevate more than a small percentage of Nigerians above the poverty level. The failure to manage the vicissitudes of global oil markets, and to grow other sectors of the economy, has led to constant budget deficits and unsustainable national...
The issues discussed in this essay - the fundamental objectives of the Nigerian state, public accountability, and a code of conduct for state officials - have been central concerns throughout its post- colonial history. Underlying these debates have been differing views about the best political economy model for Nigeria. The...
This paper describes proposed schemes for describing and indexing two image collections and requirements for the software that would give the end-user access to thesaurus terms and a graphical display of the faceted classification structures of indexing records. Editorial cartoons comprise one collection, dance videos the other.
The gradual evolution of the material properties of a cement-based material, i.e. the stiffness of cement paste, is the result of the continuous change of the microstructure with the progress of the hydration process. Based on an existing micromechanical model for the simulation of the shear and elastic modulus of...
In this paper, the correlation of reflection loss measured by an ultrasonic shear wave reflection
method and the microstructure in cement-based material is investigated. Three cement pastes
(Portland cement type I) with different water-cement ratios (0.35, 0.50 and 0.60) cured at 25
°C were examined. The ultrasonic shear wave reflection...
The paper deals with the behavior of fluid cement pastes, formulated from Self Consolidating Concretes (SCCs), and the experimental correlation of fundamental rheological properties, such as the yield stress and the viscosity, with measurements from field tests, such as the mini-cone slump flow test. As a matter of fact, several...
Gentrification - the process in which higher income (and often younger) households displace lower income residents of a city neighborhood - has been occurring in many urban neighborhoods over the last few decades. This process changes the demographics, and often the essential character, of the neighborhood. As a result, we...
