The present study assessed the prevalence of cardiovascular risk factors in 65 Nigerian medical students attending the University of Benin, Benin City, Nigeria. Their ages ranged from 17 to 28 years with a mean age for men of 20.9 years and for women of 18.8 years. Approximately 8% of the men and 0% of the women were current cigarette smokers, whereas alcohol use was observed in 14.6% of the men and in 0% of the women. The Nigerian men had significantly higher diastolic blood pressures than...

The Ventersdorp Supergroup (2700–2750 Ma) is comprised chiefly of mafic to intermediate subaerially erupted volcanics with smaller amounts of clastic sediments. The lower unit, the Klipriviersberg Group, consists of basal basaltic komatiites overlain by basalts which show a progressive increase in Mg number and Ni content and a decrease in incompatible element contents with increasing stratigraphic height. Volcanics of the overlying Platberg and Pniel Groups consist of basaltic andesites and...

Summary This paper presents the results of an analysis of resource inputs and academic performance based on the production‐function framework. Using a quasi‐longitudinal design, ex post facto data were collected from 26 secondary schools in a Nigerian state. Multiple regression results show that there was a significant relationship between teachers’ salaries or professional qualification of English language teachers and academic performance. Five of the resource inputs considered accounted...

Abstract All planned change efforts imply a commitment to a certain view of reality, and acceptance of certain modes of realizing ends. Those assumptions constitute the conscious or unconscious bases for selecting specific courses of action and thus precede all tactical decisions. To the extent that change agents cannot identify those basic assumptions and their implications, they cannot explore the full range of effective strategies for change.

An African Grey parrot, Alex, learned to report on the absence or presence of similarity and difference between two objects. Alex was shown pairs of objects that were (a) totally dissimilar, (b) identical, or (c) similar or different with respect to one of three attributes (color, shape, or material). In the first two cases, he responded to the respective queries of “What's same?” or “What's different?” with the vocalization “none,” and in the third case he responded with the appropriate...

A nationwide AIDS education campaign in Zambia was constrained by lack of support from traditional healers. First, some of them did not appreciate the nature of the new disease, and second, others hampered the education efforts by publicly claiming that they possessed curative and/or preventive medicines for HIV infection. To overcome communication barriers, the health education unit convened a workshop for traditional medical practitioners and their orthodox counterparts. An important...

2878 children from the 2nd and 3rd grades in elementary schools were assessed for their reading ability by means of standardised tests for linguistic ability and rate of letters identification. 84 children (3%) with IQ 90 or more and no evidence of sensory or motor impairment were backward in their reading ability. They were left to proceed in their conventional educational programme for the next 3 years, then reassessed. 47 (2%) children had attained satisfactory reading skills. The 37 (27...

Geological analysis of eight trench exposures through the El Asnam fault zone, reactivated during the October 10, 1980 earthquake (M = 7.3), shows various tectono-sedimentary structures associated with large seismic events in the past. Situated on the southeastern flank of the active Sara El Maarouf fold, the trenches cut across the main 1980 fault traces and also across a secondary normal fault (bending-moment or extrados fault). The erosional action of the Cheliff and Fodda rivers on the...
