In this work, the Authors make several epidemiological observations and report a series of biohumoral data relative to a new endemic goiter area in the north-western region of the Centro-African Republic (CAR). In this province whose chief-town is Bocaranga, living conditions are very poor and primitive, manioca being the staple food. The survey was carried out in 11 rural schools and in 2 schools in the chief-town; 4009 subjects were examined; 2839 were males, 1170 females. The goiter...

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 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...

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...
