Editorial: The bigger picture

Formal scientific experimental investigations tend to rely on comparing situations where differences are to some extend directly controlled, or at least known. However, it is clearly impossible to investigate, in such a manner, every detail of life, or even a slightly narrower aspect like ‘healthcare’ – by examining each choice and evaluating its role in a ‘total package’ of ‘lifestyle’, ‘care’ or ‘policy’. The current edition of the SACEMA Quarterly features several pieces grappling explicitly with this challenge of understanding a bigger picture than any particular ‘scientific investigation’ can formally take on.

Editorial: On complexity, realism and usefulness of individual-based models

For individual-based models (IBMs) in epidemiology, thinking about links between a model’s complexity, its closeness to reality and its usefulness is pertinent. This is because the bottom-up, modular and hierarchical structure of this type of models makes it relatively easy to increase the level of heterogeneity and complexity represented by the model. Moreover, the rationale for doing so is often a desire to build more realistic models. The implicit belief is that by virtue of being more realistic, models also become more useful. But is this necessarily true?

Editorial: Rethinking our indicators of impact and excellence

As epidemiologists we constantly think about indicators and metrics. Given the well-known limitations of simplifying complex dependencies to one-dimensional indicators, isn’t it surprising that many academics have bought into the practice of measuring the quality and impact of their work by a handful of metrics? While books have been written about the need for more and better indicators of impact and excellence in academia, surprisingly little attention is given to the challenge and value of being engaged and excelling in non-academic activities. Some ideas around this are presented in this editorial.

Editorial: HIV, TB and malaria: Is the end in sight?

The history of sub-Saharan Africa has been defined and determined to a large extent by the struggle against tropical diseases, many of them vector borne, including malaria, leishmaniasis, trypanosomiasis and many others. To add to this burden our continent has now to deal with the ravages of HIV and the consequent rise in tuberculosis. In this issue of the SACEMA Quarterly we discuss some of the key problems and ways in which we might be able to address and mitigate some of the challenges that we face in this regard.

Editorial: A changing of the guard at SACEMA

We are changing the guard at SACEMA. Alex Welte, who has managed “the shop” so effectively for the last five years has decided to step down. His successor, Dr Juliet Pulliam of the University of Florida, is expected to succeed him in late June 2016. It is appropriate, then, to look back at Alex’s substantial contribution to our organisation.
