Researchers collect sociological data for rural development projects throughout the world, sometimes with inefficient or imprecise methods. Questionnaires and interviews are routinely used to ask people directly what they think and know about the conditions and events that affect them. Yet the results derived from these methods may be biased. Many have recognised the difficulties of information gathering (Olawoye, 1985; Opio-Odongo, 1985; Phillips, 1973; Gilmour, 1988; Chambers, 1980)....

The diminishing number of African American teachers in the field of special education continues to be a pervasive problem in education. Minority children, especially African American children, are subject to the pernicious effects (e.g., inappropriate identification, assessment, and placement) of the misperceptions and attitudes of European American teachers who tend to be discordant with these youth. A review of the existing literature relevant to the disparity between the cultures of...

To identify disabilities and to determine their prevalence, age of onset and perceived cause in one urban and three rural areas in Northern Ethiopia.A community based cross-sectional study of households that were selected by systematic sampling. Trained enumerators identified individuals with physical disabilities or epilepsy who were 5 years of age or older.The overall prevalence of disability in 4214 individuals was 4.9%. The more common forms were walking difficulty (1.7%), loss of vision...

Wondogenet is located at the Eastern margin of the Main Ethiopian Rift. The geology of the area consists of volcanic rocks (ignimbrites, basalts, tephra) and volcano - lacustrine sediments of Plio - Pleistocene age. Morpho - dynamic activities have developed rugged and dissected landscape. These have been coupled with frequent heavy precipitation and accelerating human impact to produce frequent landslide problems. In this study landslide occurrences and their relationships with various...

In early September, throughout south central Africa, seasonal clearing of dry vegetation and the production of charcoal for cooking leads to intense smoke haze and ozone formation. Ozone soundings made over Lusaka during a six-day period in early September 2000 recorded layers of high ozone (greater than 125 ppbv at 5 km) during two stagnant periods, interspersed by a frontal passage that reduced boundary layer ozone by 30 percent. Smoke aerosol column variations aloft and total ozone were...

The impact of public education expenditure on human capital, the supply of different labor skills, and its macroeconomic and distributional consequences is appraised within a multisector CGE model. The model is applied to and calibrated for two Heavily Indebted Poor Countries (HIPCs), Tanzania and Zambia. The simulation results suggest that education expenditure can raise economic growth. However, to maximize benefits from education expenditure, a sufficiently high level of physical...
