On many projects, the design team worked with a "man on the ground" – a community representative who was mouthpiece and interpreter for the community in which interventions were being proposed.
His advisers have helped him map out a path in which the preservation of American sovereignty is uppermost (a popular theme), and in which interventions abroad are kept to a minimum.
However, this article simulates a project in which interventions are mainly safety-based.
The insights are illustrated with two cases in which interventions designed to stimulate diffusion have had differential success: energy efficient light bulbs and low temperature laundry.
This again emphasises the way in which interventions must be considered in their proper spatial context, and is encouraging since it suggests that informed placement has the potential to compound the positive effect of policing.
Therefore, in many situations, any degree of automatic response will be more than adequate, especially given the status-quo in which interventions tend to be manual, with little automated assistance, e.g. using a pager or telephone.
Difference-making in this manipulationist sense is understood as a relationship between variables in which interventions on cause variables can be used to change the value of effect variables (see the entry on causation and manipulability).
This assessment should be based on well-conducted clinical trials in which interventions are provided in a routine service setting, and in which benefits are assessed among other things on the basis of the patient's perceived quality of life.
Because understanding the context in which interventions are implemented is imperative for effective pragmatic trials and dissemination and implementation research, the use of mixed methods is critical to understanding trial results and the success or failure of implementation efforts.
Schools provide the setting in which interventions aimed at preventing intimate partner violence and abuse (IPVA) are delivered to young people in the general population and a range of programmes have been designed and evaluated.
The connection between prefrontal cortex damage and cognitive enhancement may not be immediately obvious: brain injury in fact provides a striking context in which interventions are made to enhance cognitive or behavioral ability [50].
