"He saw himself as a man-manager and was a public voice in the drive to reform Scotland's penal system: brighter, better-equipped halls, a strong emphasis on vocational training, education and counseling, no more overcrowding, no more brutality."
I use commas instead of semicolons here because semicolons project more of a pause in the thought process, as opposed to a simple continuation of a list (as indicated by the colon). But I'd like to know precisely what was meant by "man manager"; if they meant "a man and a manager", a slash would be more appropriate.
