This might be related to file perceptions of caregivers on the causes, which could influence file treatment they proffer. The study was conducted among caregivers in Ife central Local Government. Results: Most mothers perceived that fever could be caused by malaria, teething, hot weather, cough and that diarrhea could be caused by teething, eating contaminated food, drink and water, dirty environment and feeding bottles. Illness behavior was poor, as most waited at least one day after the onset of symptoms before taking any action. Choice of treatment was mostly influenced by health education messages received from health workers and mass media. Discussion and conclusions: Caregivers had a fairly correct perception of the causes of fever, but had incorrect perceptions of the causes of diarrhea. There is need to educate caregivers on the causes of diarrhea, and appropriate treatment measures.展开更多

A simple Mincer earnings regression shows that the rate of return to schooling for wage earners is two percentage points higher than that for the self-employed. After correcting for bias in sample selection, the expanded Mincer earnings equation estimated the rate of return to schooling for wage earners at between 5.3 and 6.8 percent. From the standpoint of training, we found that the simplest form of training, short-term training and formal training played an important role in promoting migrant workers’ repeat mobility. However, the simplest form of training did not have a significant effect on earnings,whereas short-term and formal training played an important determining role in this respect. Moreover, rights protection issues such as wage arrears also had an important effect on migrant workers’ repeat mobility. In handling heterogeneity and endogenous educational variables among migrant workers, the authors found that the years of schooling of the parents of migrant workers were not an ideal instrumental variable.展开更多
