Fiscal sustainability analysis in selected SADC region countries with emphasis on South Africa: dynamic modeling, nonlinear causality, and machine learning approaches

Abstract

<ns4:p>Global suicide rates owing to disaster impacts have been confusing because of varied and unclear results. This study aimed to investigate how suicides have occurred worldwide during disasters. The methodology used included a systematic literature review and comparative analysis. The disaster exacerbation (X, bad human nature, or suicide rate rise) perspective was compared with the disaster resilience (Y, good human nature, or suicide rate fall) perspective to extract disaster ecology (Z, neutral human nature, or suicide rate fluctuation) perspective from international leaders, government officials, researchers, and disaster victims. A major theme was that the four stakeholders would adopt the Z perspective based on the fusion of X and Y perspectives (leading to X+Y=Z), while embracing heterogeneous research, proactive and long-term strategies, education, and so on. This study relied heavily on the large-scale dynamics of suicide rates than previous studies.</ns4:p>
