ABSTRACT This study assessed the productivity and efficiency of airports in Nigeria employing the method of Data Envelopment Analysis (DEA).Two variants of DEA models were estimated and their outputs compared in order to enhance the robustness of the study. These models include the one based on Constant Returns to Scale (CRS) to characterise the input-output combinations and that based on Variable Returns to Scale (VRS). It is sometimes argued that DEA models generally tend to overestimate e...

ABSTRACT Housing has been described as an unstructured, complex, multi-dimensional phenomenon and its delivery as an important social policy issue. However, housing delivery in Nigeria is enmeshed in a myriad of perennial problems: huge housing deficits; acute shortages; overcrowding; high costs of building, renting and maintenance of houses. These are the outcomes of the extant policy driven persistently by the provisions approach frameworks that largely depend on implementation theory and ...
Abstract The study evaluated the effect of supply side factors on broadband penetration in Nigeria. The study analyzed the collective effect of supply side factors and the individual effect of supply side factors on broadband penetration in Nigeria. Two research questions were answered and two hypotheses tested. The population of the study consisted of 215experts from the major communication companies in the South East of Nigeria. The data used for this study were the socio-e...
ABSTRACT This study was to explore the effectiveness of the strategy adopted by the Government of Republic of Zambia to sustain rural water sources of boreholes fitted with hand pumps, using a case of Chongwe District. The Government of the Republic of Zambia adopted a strategy to reduce the rate of non-functional hand pumps for sustaining rural water supply under the National Rural Water Supply and Sanitation Programme (NRWSSP). Under the NRWSSP, the Sustainable Operation and Maintenance Pro...
ABSTRACT Online Role-Based Access Control (RBAC) is a flexible and policy-neutral access control technology that helps to reduce risk in management system. Role-based policies regulate the access to the information on the basis of the activities users perform in a system. The software was developed to reduce risk, conflict, fraud and stress that are daily occurrence in Tertiary Institutions. It motivates the subordinate to do better and perform well. The driving motivation for Online RBAC i...
ABSTRACT This research work deals on efficient contract management and its effect on project delivery. The need for the research arose due to rampant project delays and abandonment in the country and their adverse effect on the national economy. Both primary and secondary data sources were used to obtain the data for the research work. A structured questionnaire based on the 4-point lickert scale was used to collect data from the respondents. The results of the analyses indicate that there...
ABSTRACT Background: Tuberculosis (TB) remains a major threat to public health despite several efforts to curb the disease. Contributions made by TB control programs have been tremendous; however, the emergence of multi-drug resistant (MDR) tuberculosis is a big threat to the control efforts and calls for innovative measures to mitigate the effect. New TB control programs with a comprehensive approach to dealing with MDR-TB is needed globally. In particular, new nonsputum based diagnostic to...
ABSTRACT Application of IT in institutions of higher learning has become unavoidable and remains constantly increasing. Many institutions are investing heavily in IT in order to stay competitive.
