I was asked to present at the Public Relations Institute of Ireland recently and also at a seminar for not for profit and public sector communications managers, organised by Mentor Digital.
In Dublin I spoke about the professionalism required in PR and communications; and in London about the role of social media within the not-for-profit and public sectors.
You can find both presentations here: http://www.slideshare.net/pinchpointcommunications
Hope they are of benefit to you.
with thanks
