"Power can be portrayed as a resource - a sort of reservoir of force- that can be used by an agent to change the behaviour of another. The actual application of that force is what we mean by "influence". Through the application of power, A has the capacity to influence B in ways that s/he would otherwise not behave. As Hardy (1995, p.xiii) has pointed out, this rather simple notion has been "challenged, amended, critiqued, extended and rebuffed over the years, but nevertheless remains the starting point for a remarkably diverse body of literature."'
