In my study of sharing, my aim to is to kind of let the field lead me. What I mean by that is that if a phenomenon is described as one of sharing by the people involved in it, then I should have a look at it. I recently came across two organizations that call themselves organ sharing organizations. On the face of it, this is an odd use of the word sharing: organs are not shared, they are donated. More to the point, the donor, at the time the donation is made, is dead.
From a very brief and not at all scientific scan of the website of the United Network for Organ Sharing, it seems that when describing their activities, the word “donation” is used, and not “sharing”. That is, the “sharing” part is only in the title of the organization.
If there is sharing, it could be between different states and organizations – sharing knowledge about donors and waiting lists – but I’m not really sure about that either.
