Dividend policy remains an important topic in modern corporate finance. Researchers, managers, and business owners seek to understand the optimal dividend policy. This study examined dividend policy as a driver of corporate growth in sub-Saharan Africa: evidence in Nigeria. The ex-post facto research design was adopted to analyse how dividend policy spur the growth of active insurance companies in the Nigerian Stock Exchange using secondary data of the sampled firms for 2007 – 2018 while utilising descriptive and inferential (regression) statistics in data analysis. The findings reveal that dividend policy in terms of dividend payout has an insignificant negative effect on corporate growth of insurance companies in Nigeria (?= -8.09E-05, p=0.77; Adjusted R2=0.4093; F(4,139)=3.29; p=0.00 with the controlling effect of efficiency, firm age and leverage which have a significant effect on corporate growth of insurance companies in Nigeria. Specifically, the study reveals that efficiency has a significant negative effect on corporate growth (?=-5.29, p<0.05); while firm age discloses a significant positive influence on corporate growth (?=0.417, p<0.05); as leverage exerts a significant negative effect on corporate growth (?=0.052, p<0.05). Therefore, the study concludes that dividend policy does not significantly drive insurance companies' dividend payout growth. The study recommends that insurance companies' management retain more of their profits, improve their efficiency, and control their leverage to further growth.

RTS,S/AS01 is the most advanced vaccine to prevent malaria. It is safe and moderately effective. A large pivotal phase III trial in over 15 000 young children in sub-Saharan Africa completed in 2014 showed that the vaccine could protect around one-third of children (aged 5–17 months) and one-fourth of infants (aged 6–12 weeks) from uncomplicated falciparum malaria. The European Medicines Agency approved licensing and programmatic roll-out of the RTSS vaccine in malaria endemic countries in sub-Saharan Africa. WHO is planning further studies in a large Malaria Vaccine Implementation Programme, in more than 400 000 young African children. With the changing malaria epidemiology in Africa resulting in older children at risk, alternative modes of employment are under evaluation, for example the use of RTS,S/AS01 in older children as part of seasonal malaria prophylaxis. Another strategy is combining mass drug administrations with mass vaccine campaigns for all age groups in regional malaria elimination campaigns. A phase II trial is ongoing to evaluate the safety and immunogenicity of the RTSS in combination with antimalarial drugs in Thailand. Such novel approaches aim to extract the maximum benefit from the well-documented, short-lasting protective efficacy of RTS,S/AS01.

Background: Suicidal behavior in adolescence is a public health concern and has serious consequences for adolescents and their families. There is, however, a paucity of data on this subject from sub-Saharan Africa, hence the need for this study. Aims: A cross-sectional multistage survey to investigate adolescent suicidality among other things was undertaken in rural northeastern Uganda. Methods: A structured protocol administered by trained psychiatric nurses collected information on sociodemographics, mental disorders (DSM-IV criteria), and psychological and psychosocial risk factors for children aged 3–19 years (N = 1492). For the purposes of this paper, an analysis of a subsample of adolescents (aged 10–19 years; n = 897) was undertaken. Results: Lifetime suicidality in this study was 6.1% (95% CI, 4.6%–7.9%). Conclusions: Factors significantly associated with suicidality included mental disorder, the ecological factor district of residence, factors suggestive of low socioeconomic status, and disadvantaged childhood experiences.
