Thanks, Mario I have to admit that wasn't aware of researcherid. However, note that it is only "free" in the sense that you need access to ISI Web of Knowledge, which certainly isn't free! In all citation analyses, there is the problem of disambiguation, whether with WoS, Google, PoP or Scopus. There have been several studies on this. I also agree that the same tool should be used for all respondents to a survey, at least if possible. When I suggested the use of PoP, I had surmised that the researcher might want to extend the search from the self-selected respondents to other known scholars in the field. I almost added a note to say that it should be used with caution, but in research doesn't that go without saying? And with the h-index, you will of course get different results next year!

You have a bit more control about names there than in google scholar citations. I've found that the number of cites does differ between them, it's always larger in google scholar. > > I think it's important to declare which search tool is being used and, as Brian implies, it should be the same for all respondents to the survey. > > Mario > > -----Original Message----- > From: A UK-based worldwide e-mail broadcast system mailing list [mailto:[log in to unmask]] On Behalf Of Francis, Brian > Sent: 01 March 2013 13:07 > To: [log in to unmask] > Subject: Re: SURVEY: h Index questionnaire > > Hi, > While publish or perish is a great utility for unusual author names, it is hopeless at sorting out which publications are yours and which are not for more common names - as it appears to work only on surname and initial/first name the last time I looked. There is also a limit of 1000 publications on the search - a problem if many of them belong to other people with the same name as you. Google scholar citations in contrast has a clever algorithm that somehow manages to identify your own publications and reject all others belonging to others with the same name as you. My advice is to steer clear of Publish or Perish if you have a name that is even remotely common! > > Anyway, from a methodological point of view, surely the same tool should be used to estimate h-indices forthe user survey - it's not good statistical practice for some respondents to use one tool and some another. > > > Brian Francis > > You may leave the list at any time by sending the command > > SIGNOFF allstat > > to [log in to unmask], leaving the subject line blank. > > You may leave the list at any time by sending the command > > SIGNOFF allstat > > to [log in to unmask], leaving the subject line blank. You may leave the list at any time by sending the command SIGNOFF allstat to [log in to unmask], leaving the subject line blank.
