To compare the diagnostic performance of microscopy using Giemsa-stained thick and thin blood smears to a rapid malaria dipstick test (RDT) in detecting P. falciparum malaria in Kenyan school children.Randomised, controlled feeding intervention trial from 1998-2001.Rural Embu district, Kenya. The area is considered endemic for malaria, with four rainy seasons per year. Chloroquine resistance was estimated in 80% of patients. Children had a spleen rate of 45%.A sample of 515 rural Kenyan...

Abstract The burden of chronic illnesses is rising throughout the world but information on barriers to managing such diseases in developing countries is scarce. Qualitative data from focus group discussions and interview transcripts from a longitudinal study involving 22 households in urban, coastal Kenya were analysed. Themes around barriers to chronic illness care were identified and a conceptual framework developed which described relationships between these themes. The main barrier to...

This study focused on the relationship among strength, endurance and power performance characteristics of untrained university undergraduates following three different modes of plyometric training. Participants were 40 untrained volunteer male undergraduates, randomly assigned to three experimental plyometric training groups of depth jumping, rebound jumping and horizontal jumping over a distance, and a fourth group which served as the control. The three experimental groups were made to go...

Students' perceptions and value orientation could assist curriculum developers to design and implement a Physical Education (PE) curriculum that would address the needs of post-independent South African schools. PE and School Sport (SS) in South Africa demonstrate extremes and inequities. Contrast is visible in all aspects of South African life, but most significant in education. White and urban schools are relatively problem free, whereas black and rural schools have been adversely affected...

Adolescence is one of the most critical phases in the lifespan of human beings and is characterised by experimenting and recklessness that lead to social problems, diseases and deaths among adolescents. This poses a major educational challenge to bring about a lifestyle change among adolescents. The main problem of the study was to determine the perspectives of Life Orientation (LO) teachers regarding the implementation of LO with specific reference to the Learning Outcome Physical Education...

Skipping is a sportive activity consisting of relative jumping cycles of skipping rope round the body. The main purpose of this study was to establish the relationship between heart rate (HR) and skipping frequency in children, using a regression analysis. A second objective was to determine the intensity corresponding to the lowest heart rate and least energy cost of rope skipping. A Repeated ANOVA design requiring the subjects to perform skipping at three different trials and at five...

Abstract A multi‐proxy analysis of microfossils from sedimentary records, together with evidence from historical and archaeological data, has provided evidence of vegetation dynamics and human environment interactions in western Uganda for the last 1000 years. Pollen, fungal spores and phytoliths extracted from sediment cores obtained from a papyrus swamp at Munsa archaeological site indicate a relatively wet and forested environment in western Uganda prior to ca 1000 yr bp (cal 977–1159 ad...

Abstract In this paper, the influence of climate variability and change on the environment was studied over southern Africa using ground‐based and remotely sensed data. A time series analysis of rainfall and temperature anomalies indicated that there was a high rainfall and temperature variability in the region. The influence of global teleconnections on rainfall patterns over southern Africa showed that in some areas there was a spatial variation in their strength, increasing from west to...

Drought and its associated impacts have been causing critical problems for agriculture, vulnerable communities and overall development for many years in South Africa. Impacts of drought such as the effects on a regions’ climatology, increases in food insecurity and food prices and the integration of drought with factors such as the HIV/AIDS epidemic have led government to introduce various policies dealing, in particular, with drought risk. By means of examining government documents, journal...

We describe a new species of squeaker frog (Arthroleptis) from Mt. Manengouba in southwestern Cameroon. The new species is distinguished from other Cameroonian Arthroleptis by moderately larger body size; a darkened throat and posterior thigh, both with many white spots; and, in females, a fourth finger longer than the first and second fingers. This species corresponds to a Cameroonian taxon previously identified as Arthroleptis adolfifriederici but which has been long recognized as...

We investigated how education policy was mediated at a representative number of Western Cape schools, from 1997 to 2003, using the structure, symbolic, human resource and political frames of Bolman and Deal (1997) as the basis of the investigation. The investigation produced diverse research findings. At the one end there were a majority of representative councils of learners that received the full support of the main role players. These councils were fully functional and were making a...

A survey was conducted to evaluate the pattern of sexual behavior and contraceptive use among female students aged 15 to 24 years attending tertiary institutions in Ilorin, Nigeria.A valid and reliable semistructured questionnaire was self-administered to a sampled population of 600 students aged 15 to 24 years.Of the 600 students, 562 (93.7%) completed the questionnaire. Most (98.6%) of the respondents were unmarried, 77.6% have had sexual intercourse, 67.8% have had an unwanted pregnancy...

The study was conducted to find out the attitude of students towards the use of cooperative, competitive and individualistic learning strategies in Nigerian senior secondary school physics.The design selected for this study was quasiexperimental.A total of 140 students took part in the study and they were selected by a random sampling technique.A structured questionnaire titled Students' Attitude Towards Physics Questionnaire (SATPQ) on 4-point scale was used to collect the data.The...

One of the greatest challenges facing school nurses is that of identifying and using appropriate strategies to meet the health education needs of adolescents in regard to prevention of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). This study examined the effects of HIV/AIDS preventive health education with parental involvement on students' attitude toward HIV/AIDS prevention in Akwa Ibom State, Nigeria.The study population comprised students from three of...
