One of the most interesting ways to evaluate a researcher is to look at how many highly cited publications they have. The H-Index (developed by Jorge Hirsch at UCSD) asks, for example, for the number of papers cited by at least that many other papers.
Here is an attempt at this, although Google Scholar and similar citation databases had real difficulty disambiguating the different authors named Douglas Jones. In addition, some articles are indexed under multiple variant titles because authors don't always cite things consistently. For example, some authors cite the web site from which they downloaded an electronic copy of the paper instead of the journal in which it was published. In the following, the notation 3 + 2 means the search engine mentioned found 3 citations under one title plus 2 under another.
Tentatively, then, as of late April, 2013, I have an H-Index of 14.
A person's Erdös number is the length of the chain of co-authored publications linking that person to the prolific mathematician Paul Erdös. Since Erdös' primary contribution to mathematics may well have been the number of papers he coauthored during his career, this number is of little practical use except perhaps as a source of illustrations for discussions of graph theory. There can be multiple paths through the coauthor graph, and finding the minimum path length is not always easy. Here is a worked exercise that locates many paths all that have the same length:
Douglas Jones (Erdös number 4), coauthor of Evaluation of Voting Systems with:
Douglas Jones (Erdös number 4), coauthor of SOBA: Secrecy-preserving Observable Ballot-level Audit with:
Douglas Jones (Erdös number 4), coauthor of Internet Vopting in the U.S. with:
A person's Bacon number is defined similarly to the Erdös number, but using the relationship "appeared in the same movie as" instead of "coauthored a paper with" and counting from the actor Kevin Bacon instead of the mathematician Paul Erdös. Bacon numbers have about as much utility as Erdös numbers, except that some of the names are more glamorous.
I've never acted in a movie, but thanks to several documentaries, I'm listed in IMDB, so if the definition of a Bacon number includes documentaries, I can claim a Bacon number of 3:
