***** To join INSNA, visit http://www.sfu.ca/~insna/ ***** I am conducting a course on social research methods and would like to introduce the students to snowball sampling from a network perspective. Any suggestions regarding articles that specifically address this technique and offer interesting results in the field of SNA are greatly appreciated. Please keep in mind that these are undergraduates. Thanks in advance, Jim Luther University of Pittsburgh _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.sfu.ca/~insna/).
