Conceptual modeling of nodding syndrome: A system dynamics and sequence approaches

Conceptual modelling of nodding syndrome (NS) has hardly been considered in most scientific literature although symptoms of the disease have been widely studied. A conceptual model is a representation of hypothesis about a system under investigation and enables a comparison between hypothesis and data. Since nodding syndrome is an unexplained neurological illness that mainly affects children aged between 5 to 15 years, without specific diagnosis and treatment, the aetiology remains...

A system dynamics tool for higher education funding and quality policy analysis

Conceptually, the level of funding of higher education activities is directly proportional to its strategic directions/implementations and hence quality. In developing countries, these dependencies are far from straightforward due to ad-hoc reactions to reduced funding. This paper contributes to the development of tools for this management challenge. We investigate the dynamics of higher education funding and ensuing impact on part-time teaching, staff to student ratios, staff development, research productivity, and...
