The spatial distribution of volcanic vents in the northern Ethiopian Rift has been analysed in terms of their self‐similar clustering. The fractal distribution of vents has been computed for the monogenetic vents (cones, domes and maar) occurring along the rift valley and in the rift margin. The self‐similar clustering of vents has been computed through the analysis of vent centres coordinates by means of the two point correlation method. The vents of the northern Main Ethiopian Rift display...

This article discusses the way the French army's use of torture during the Algerian war (1954–1962) is taught in terminale history class in contemporary France. In recent years the issue of torture has re‐emerged in the public sphere and has attracted considerable media coverage. Through a case study of this vector of memory, the article appraises the teaching of history by drawing on interviews with historians, teachers and pupils in France as well as on written sources such as textbooks...

This paper engages with some of the tensions raised by critical literacy in the post-apartheid South African context, both theoretically and in classroom practice. I examine Kress's (1996; 2000) challenge to the notion of 'critique', exploring the way in which critical literacy pedagogy is linked to the particular socio-political and historical context in which it takes place. As an illustration of this, I look at the development of critical literacy in apartheid and post-apartheid South...

Home schooling may be defined as an alternative to on-site institutionalised schooling. Most education systems accommodate home schooling but such arrangements are regulated in various ways. This article reports on an investigation into home schooling in South Africa as an consequential part of the education system of the country. A literature review of the context, nature, scope and current issues of the home schooling movement, in other countries as well as in South Africa, is presented as...

A study of the active Mount Cameroon volcano, located south west along the Cameroon Volcanic Line, was carried out during the 1999 volcanic eruption, using Landsat Enhanced Thematic Mapper (ETM) imagery. It investigated geologic deformations expressed as faults, cracks and lineaments resulting from the eruption. Various image processing techniques were tested and compared in order to detect the most effective output. Principal Component Analysis was found to be useful to determine the extent...

Following the death of 67 boys in a fire tragedy at Kyanguli School in rural Kenya, the level of traumatic grief was assessed in a sample of 164 parents and guardians whose sons died in the fire. The study was cross-sectional. Counseling services were offered to all the bereaved parents soon after the tragedy. The subjects were interviewed using the Traumatic Grief Scale. A group of 92 parents/guardians was interviewed 2 months after the event, while the other group of 72 was assessed 7 days...

Abstract Pual Ridge is a deep-marine, felsic volcanic edifice in the eastern Manus back-arc basin (Papua New Guinea) with an estimated volume of ∼6 to 9 km 3 . It is 1–1.5 km wide, 20 km long and rises 500–600 m above the surrounding ocean floor. The active PACMANUS hydrothermal field on the crest of Pual Ridge at 1640–1690 m below sea level was the target of Ocean Drilling Program Leg 193. Variably altered dacite lavas have been recovered from the subsurface of a low-T discharge site...

The authors describe their experience in using soft OR methods to facilitate a one-day workshop to support the planning processes of a community-based educational trust in South Africa. This workshop brought together the contributions of over 40 people who were involved either in the overall management of the Trust or in the delivery of its courses. It had been agreed to make use in the workshop of the philosophy and methods of the Strategic Choice Approach. To facilitate participation by...

Drawing from Catholic teaching this paper acknowledges that these communities are obliged to provide pain relief for these victims. For reasons that will be studied in detail treatments beyond this should be regarded as extraordinary and therefore not an obligation. This is based on the fact that ordinary means of treatment are relative to the availability of resources. The resources in the sub-Saharan region are not sufficient to provide any treatment beyond pain relief. This papers focus...

There is increasing divergence in the academic outcomes of African American males and females. By most accounts, males are falling behind their female peers educationally as African American females are graduating from high schools at higher rates and are going on to college and graduate school in greater numbers. Some have suggested that school completion and performance is associated with how students feel about themselves. The purpose of this study was to explore gender differences in the...

Using critical race theory as a framework, this article examines the access and availability of Advanced Placement (AP)1 courses and how they impact educational outcomes for Latina/o2 and African American students. To begin thinking critically about enrollment patterns of AP courses we ask the following questions: How do school structures, practices, and discourses help maintain racial and ethnic discrimination in access to AP courses? How do Latina/o and African American students and...

The rise of malaria in Africa is a subject of much debate. A new analysis emphasizes the influence of rainfall, but there appear to be few areas where climate has been a major driver of this change.

There is an urgent need for effective interventions to improve the sexual and reproductive health of adolescents. Reliable data on the sexual health of adolescents are needed to guide the development of such interventions. The aim was to describe the sexual health of pupils in years 4 to 6 of 121 rural primary schools in north western Tanzania, before the implementation of an innovative sexual health intervention in 58 of the schools.A cross sectional survey of primary school pupils in rural...
