Item Duration of high school education on early fertility and marriage: evidence from a policy change in Ghana(International Journal of Social Economics, 2023) Boahen, E.A.; Nunoo, J.; Opoku, K.Purpose – The objective of this paper is to examine the effect of spending one extra year in high school on early marriage and childbirth. Design/methodology/approach – The study takes advantage of the education reform in 2007 that extended the years of high school education by one to conduct a quasi experiment. The marriage and fertility outcomes of women who completed a four-year senior high school education are compared to those who completed a threeyear senior high school education. Findings – The findings from the study indicate that the one-year extension in high school education led to a 4.75 percentage point reduction in the probability of ever marrying by age 27 and a 6.7 percentage point reduction in the probability of ever given birth. The authors demonstrate that the extension of the duration of high school education by one year has a heterogeneous effect, as it reduced the fertility and marriage outcomes of rural girls more than urban girls. The study reveals opportunity costs and confinement effects as possible mechanisms through which the policy affected early marriage and birth. Originality/value – This study is one of the few studies that examine the impact of the duration of secondary school education on fertility and marriage. For Africa in particular, there is no such study. Thus, this study provides a unique contribution to the literature since available studies on this subject matter can only be found in advanced economies. Unlike other studies in Africa that use a design that provides the combined effect of duration of schooling and school enrolment on fertility and marriage, this design enables the authors to only look at the effect of duration of schooling on fertility and marriage.Item Effect of insecticide-treated bed net usage on under-five mortality in northern Ghana(Malaria Journal, 2015-08) Afoakwah, C.; Nunoo, J.; Andoh, F.K.Although under-five mortality rate seems to be declining in Ghana, the northern part of the country has higher levels of under-five mortality vis-à-vis the national rates. This research examines the correlates of the high under-five mortality among children in the northern part of Ghana, with emphasis on the usage of insecticide-treated bed net (ITN), as recommended by the World Health Organization. A total of 3,839 under-five children sourced from the Ghana Demographic and Health Survey-was used for this study. Univariate descriptive statistics was employed to describe the variables used for the empirical estimation. The maximum likelihood estimation technique was used to estimate a logit model in other to determine the effect of insecticide treated bed net usage on under-five mortality. Insecticide-treated bed net usage among children enhances their survival rates. Thus, under-five mortality among children who sleep under treated bed nets is about 18.8% lower than among children who do not sleep under treated bed nets. While health facility delivery was found to reduce to reduce under-five mortality, child bearing among older women is detrimental to the survival of the child. The study, therefore, recommends that policies targeting reduction in under-five mortality in northern Ghana should consider not mere availability of ITNs in the household, but advocate the usage of these treated nets. The study recommends to the Ministry of Health to extend their services to unreached rural communities to encourage health facility delivery to reduce under-five mortality (PDF) Effect of insecticide-treated bed net usage on under-five mortality in northern Ghana.

Severe population outbreaks of the whitefly vector (Bemisia tabaci), are usually associated with high incidence of the disease. Resistance breeding is the surest solution to TYLCV in developing viable seeds for increased tomato production in Ghana. The Wild tomato (Solanum pimpinellifolium L.) is a recognised crop Wild species (CWS) with resistance genes to different diseases including the TYLCV disease and possesses good fruit quality traits in Ghana. Three (3) cultivated tomato varieties and seven breeding lines developed from crosses between the Wild tomato and three hybrids, three backcrossed lines and the Wild tomato were evaluated with their parents against TYLCV disease under local field conditions. Field appraisal of whitefly populations, disease incidence and severity, agronomic and yield characteristics of the tomato varieties/breeding lines were undertaken to hasten selection of tolerant/resistant varieties or breeding lines in the breeding programme. Wild tomato (ISSAP = 0.31 and ISSDP = 0.76) and Woso (ISSAP = 1.90 and ISSDP = 2.27) recorded the least and highest average symptom severity on all plants (ISSAP) and diseased plants only (ISSDP); while the least and highest disease incidence was recorded by the Wild tomato (11.10%) and Roma (43.05%). Roma which recorded the highest population of whiteflies in the dry season also exhibited the highest symptom severity on all plants as well as diseased plants during the study period. There was a significant symptom relapse in Wild tomato and Woso x Wild in 6-8 WAT for both ISSAP and ISSDP. Number of fruits per plant, ISSAP and ISSDP were positively and/or inversely correlated (r = 0.98, 0.93, -0.83) with average whitefly count, percent disease incidence and yield (t/ha).
