RESUMEN
This pooled dataset presents data collected through four (4) sequential cross-sectional surveys of undergraduates in six (6) selected Nigerian universities. The data were collected from a total of 12,615 undergraduates studying courses in the social sciences, sciences and engineering disciplines. The surveys assessed entrepreneurship interest, background and experience of the respondents. The dataset is useful for research, policy and practice in several ways. Coming from surveys repeated at intervals of between four and five years, the dataset allows for an assessment of the impacts of the compulsory entrepreneurship training that was introduced in the Nigerian university system at about the time of the first survey. It can also be used to quantify the potential pool of future entrepreneurs among the highly educated Nigerian youth. Additionally, the dataset presents a full entrepreneurship profile of a very large pooled cross-sectional sample of educated young people in the largest and most populous nation in sub-Saharan Africa. Consequently, researchers, policymakers, donors and other development practitioners seeking to characterize and design appropriate interventions for youths in the developing world will find this dataset valuable.
RESUMEN
The activity levels of 238U, 232Th and 40K in soil surrounding major office complexes in Covenant University were analyzed for radiological hazards to determine the safety of the residents in such environment. Sixteen (16) soil samples were collected, prepared and sent to Acme laboratory in Canada for analysis with the use of high purity germanium detector. The mean activity concentrations of 238U, 232Th and 40K were found to be 45 ± 10, 135 ± 8 and 195 ± 20 respectively. The concentrations of 238U and 232Th were found to be higher than the world recommended standard of 35 and 30, while the result for 40K was noted to be lower than the world safe limit. The average values of Raeq, D, AED, Iyr, Hex and ELCR in this study were estimated to be 252.33 Bq/kg, 110.15 nGy/h, 0.13 mSv/y, 1.78, 0.68 and 0.47 × 10-3 respectively. It was noticed that none of the measured parameters was higher than the internationally recommended safe limits. 232Th was found to be the major contributor to the environmental radionuclides in the area of study. Therefore, the inhabitants of the office complexes whose environment was assessed are considered not be exposed to any radiological hazards.
