Abstract In some countries of the Middle East and sub-Saharan Africa, it was studied the impacts of governance and FDI on environmental pollution over the period of 1996–2018 by the Panel Quantile and Granger causality methods. The countries were selected by considering two different measurements, EPI (2020) and governance index (2020). Accordingly EPI(2020), these countries have low scores in terms of environmental quality and in governance index(2020), they have bad governance scores because of inefficient regulatory structures, government bureaucracy, weak law enforcement, etc. Panel Quantile regression revealed the evidence of the long-run relation among the environmental pollution, the governance and FDI. Accordingly Quantile regression results, governance has the greatest positive effect on CO2 emission. Both traditional and Dumitrescu-Hurlin (DH) causality methods found the evidence of causality among governance and environmental pollution in the context of two parameters of governance, as the evidences of unidirectional causal nexus from political governance and FDI to environmental pollution and from economic governance, and FDI to environmental pollution.

The Impact

Although an active body of literature exists on the relationship between government size and corruption, different findings proliferate the literature due to the nuances of geographical context, methods, and variables employed. The paper employs the novel method of moment quantile regression with fixed effects over the period 1984–2018 to investigate the dynamic impact of government size and press freedom on corruption in Sub-Saharan African (SSA) countries. The main contribution is to examine the impact of government size and press freedom across the conditional distribution of corruption in SSA. The findings show that the impacts of government size and press freedom are heterogeneous across the conditional quantile distribution of corruption. Among the most corrupt countries in SSA, larger government size and press freedom significantly increase corruption. Some policy recommendations are offered based on these findings.

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.
