Just what is it that politicians hope to gain from interventions of this kind anyway?
Interventions of this sort tend to be as superficial and poorly targeted as the widely hyped Portas Pilot programme, and will almost certainly generate the same indifferent results.
More broadly, Cameron and Sarkozy's Libyan policy managed, in a few short months, to expose and magnify the conflicting political, military and diplomatic faultlines that render international interventions of this sort so materially hazardous, morally questionable and financially fraught.
Until that debate is settled in America – which, remarkably, will not be any time soon – interventions of this sort will be nothing more than a distraction.
But the interventions of this new club of donors tend to focus on infrastructure, agriculture and opening up the extractive industries rather than health.Ultimately, African governments will need to cover costs in the health sector.
These are not issues that should be glossed with vague assurances; the government ought to have specific guidelines that a) can be publicly debated, and b) will constrain the administration, as oversteps will be apparent.Convenience or politics are not good motivations for interventions of this sort.
A few interventions of this type have been evaluated using randomised controlled trials (RCTs), the most rigorous design to evaluate the effects of biomedical and behavioural interventions.
It is a common problem that interventions of this type are often established with no equivalent control group on which to base an evaluation of programme effectiveness.
When early interventions of this sort focus on matching adult language to the child's current focus of attention which makes the experienced more personalized, there are significant long-term positive effects on the academic success of young children (Cornerstones 2009).
On the contrary, the PSP carries out, on average, more than 15,000 community or neighbourhood policing operations a year, and in sensitive urban areas, interventions of this nature have been increasing.
This study is the first to use a controlled trial design to evaluate this type of intervention and is valuable in showing that this design can be used in interventions of this kind, and also the difficulties involved.
