The early Proterozoic Transvaal (TR) and Soutpansberg (SB) successions in South Africa are composed of sediments and variable amounts of volcanic rocks. Volcanic rocks are chiefly tholeiitic in character and in some formations range from mafic to felsic in composition. Except for Machadodorp basalts, all volcanics exhibit Nb-Ta depletion relative to Th and REE. Machadodorp basalts are relatively depleted in incompatible elements and some exhibit flat to depleted LREE patterns like MORB....

AbstractThis study examined the effects of teacher-directed and student-oriented remediation methods in high school physics classes in Nigeria. Students (N = 121) from three Nigerian high schools were assigned randomly to three conditions: teacher-directed remediation, student-oriented remediation, or no treatment. Results of formative, intelligence, and achievement tests indicate that the teacher-directed remediation approach was more effective for increasing performance. Educational...

The difference between developed and less developed countries resides to a great extent in the effectiveness of their administrative systems. The objective of this study is to identify and analyse the organisational constraints acting upon and within the Egyptian Ministry of Education that deter its capacity for administrative reform. Critical management processes are examined, such as policy formation, promotion procedures, planning, resource distribution, and local level decision making....

The restructuring of schools has become a major focus for educational researchers and practitioners. The purpose and goals of school restructuring have been stated in various ways. The ingredients have included: changing decisionmaking process to allow greater participation from teachers and parents,embellishing curriculum with higher-order thinking skills; planning or developing new curriculum; increasing student participation in shared learning experiences and allowing students to take...

The paper compares the costs of training for two groups of Village Health Workers (VHWs) in Tanzania, where the policy of developing a system based on Primary Health Care principles will require the training of more than 16,000 VHWs during the next decade. In the Kilombero District, one group of VHWs was trained according to the guidelines of the National Programme of the Ministry of Health, and another group followed the training programme of the Kilombero Project, based on the Swiss...

In South Africa, education is one of the social institutions manipulated by the apartheid government to develop and maintain an unequal society. In this provocative article, Es'Kia Mphahlele, a Black South African educator, describes the Blacks' struggle for educational improvement through alternative education. Mphahlele, who was forced into exile for two decades because of the stand he took against inferior education for Blacks, returned home to be part of a struggle for a system of...

To determine whether epithelial ion transport is physiologically important for lung water clearance after birth, the sodium transport inhibitor amiloride or its vehicle saline was given intratracheally to newborn full-term guinea pigs before the first breath. Guinea pigs given saline intratracheally breathed normally and had arterial O2 saturations (SaO2) greater than 94%. In contrast, guinea pigs that had an estimated 10(-4) M intra-alveolar concentration of amiloride had chest wall...

Source parameters have been determined for the earthquake (M s 5.6) that occurred offshore of Tripoli, Libya, on September 4, 1974. One nodal plane of its focal mechanism has dip 37°, strike 297°, and rake −141°, indicating oblique normal faulting. This nodal plane is subparallel to many west‐northwest striking normal faults in the epicentral area and is most likely the fault plane, indicating a component of right‐lateral strike‐slip with slip vector azimuth N84°E. Inversion of long‐period...

(1990). Loneliness and General Psychological Distress among Zimbabwean Students. The Journal of Social Psychology: Vol. 130, No. 2, pp. 273-275.

When Zimbabwe gained its independence in 1980, it experienced a loss of European skills and knowledge at all levels. This skills exodus affected both the public and private sectors. It not only impacted on who would fill vacancies but also on the mechanisms that would be used to provide inservice training. This paper discusses 3 primary providers of inservice training : 1) the Government - public sector initiatives include apprenticeships; upgrading the training of skilled workers through...

Recent studies portray African education in a state of stress. Since it is widely believed that education is critical to development, proposals for addressing this crisis have been numeroas and frequent. A knowledge base of research studies has to be created to advise the external agencies that support education in Africa. Many studies were, however, incomplete and non-scholarly. The resulting reports were not widely circulated, as they carried access restrictions imposed by the sponsoring...

In Ilorin, Nigeria, 788 cases of eclampsia were managed between 1968 and 1987, giving an incidence of 4.2/1000 deliveries. Five hundred thirty-five of the patients were nulliparous and 353 had received some form of antenatal care. There was no apparent change in the pattern of eclampsia over the years. The predisposing factors to developing eclampsia are examined and suggestions offered for the prevention of eclampsia in third world countries.

School mathematics in the 1990s is preoccupying the minds of many in the developed and developing nations. In particular, much concern has been expressed about school mathematics in the developing nations. There are doubts about any meaningful achievements in many developing nations. But there are certain areas on which many developing nations should concentrate immediately if meaningful results are to be expected in the 1990s. This paper therefore deliberates on immediate priorities or...
