La desmagnetización térmica de 75 sitios en rocas basálticas, la mayor parte a menos de 5 km de la Falla Levante, identifica direcciones de remanencia consistentes en la mayoría de los sitios. Las polaridades identificadas son Normales, Inversas e Intermedias, dominando las Inversas. Los sitios Normales e Inversos están magnetizados similarmente, 5.6±5.3 A/m, en tanto que los sitios Intermedios o direcciones indefinidas están algo más fuertemente magnetizados, 11.9±9.5 A/m. Las...

This study focused on training for development for women involved in fish industry in Lagos state, Nigeria. Three hundred and fifty (350) women involved in fishery activities were randomly selected from 10 fishing villages purposively selected for the study in the state. Structured interview schedule was used to obtain information from the respondents. This was subjected to face validity and reliability test using split half techniques (r= 0.85). The results indicate high need for training...

<p>This study analyses the academic achievement of students enrolled in part-times studies at on-campus and outreach centres at three dual-mode Nigerian universities, during the 1996/97 to 1998/ 99 academic years. Research subjects in this study were examination and record officers employed by on-campus and outreach institutions. A checklist was prepared to collect students’ grades; these checklists were then transcribed into grade points (GPAs) for data collection purposes. Simple...

L’analyse des donnees geologiques, geomorphologiques et d’occupation des sols fondee sur l’interpretation d’images satellitaires ETM + (Landsat Thematic mapper) ainsi que sur des transects realises sur le terrain met en evidence une erosion hydrique et un colluvionnement forts sur les marges externes des milieux riverains du Mouhoun a Boromo dans l’ouest du Burkina Faso. Des buttes temoins, coiffees des sols de l’ancienne plaine d’inondation et des arbres aux racines denudees, encore...

This article proposes the formation of time-honored cooperative and educational partnerships between historically Black colleges and universities (HBCUs) in the United States and universities in Africa using state-of-the art technology. Emerging electronic communication implements and the availability of information driven by the various campus networks should be key resources to support these collaborative efforts. The potential benefits of the information superhighway for the African...

ABSTRACT: This review examines twenty years of research (1985 to 2005) on African-American students in science education. This analysis identified three types of research studies on African-Americans. First, a series of studies provided status reports of African-American students' performance in science. Second, a series of studies highlighted cultural discontinuities that existed between African-American students and the culture of science classrooms. A third series of studies called for...

Ecoregional research has the potential to help address some of the huge challenges facing agriculture in developing countries by developing technologies that work under different agro-ecological conditions, and the processes by which these technologies can be adapted to work in other areas with similar conditions. The CGIAR system has been developing ecoregional research as a new paradigm for over a decade. In this paper we evaluate one of the most ambitious of these initiatives called the...

A developmental ecological model was used to identify child attributes, father characteristics, and familial factors associated with multidimensional father involvement with preschool children enrolled in Head Start. The relations between father involvement and children's school readiness were also investigated. Eighty-five African American fathers and father figures were surveyed about their involvement in child care, home-based educational and school-based educational activities....

This study was conducted on 1403 children from four Egyptian governorates. These governorates were; Alexandria, Al-Behira, Cairo and Al-Giza. The aim of the study was to define

Universal studies are an important source of stressor. Students are at high risk for mental disorders. In this study, we seek for psychological distress among Tunisian students, using GHQ (general health questionnaire).

This study employed a Ricardian model to measure the impact of climate change on South Africa's field crops and analysed potential future impacts of further changes in the climate. A regression of farm net revenue on climate, soil and other socio-economic variables was conducted to capture farmer-adapted responses to climate variations. The analysis was based on agricultural data for seven field crops (maize, wheat, sorghum, sugarcane, groundnut, sunflower and soybean), climate and edaphic...
