***** To join INSNA, visit http://www.insna.org ***** Hi I am writing a paper on data collection strategies in social network analysis. I would like to include a section on new technological devices that automatically register interaction between/among actors. I know that there are some devices out there that some researchers are using. People carry them around and they track their contacts with others (and, eventually, other information, such as length of communication and eventually voice tone). Information on these and other technological devices for automatic data collection would be very helpful. Also, is anyone aware of any publications that deal with this issue? I think that we as a community need to discuss the characteristics, advantages and potential drawbacks of such systems. Any information and views on this are more than welcome. I promise to share the results of this query with anyone who is interested. Thank you in advance for your help and comments Jorge Ávila de Lima (Associate Professor) _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
