4.4.2.2 Selection of participants and the role of the researcher
Although random selection is preferred as it minimises selection bias (Krueger & Casey
2000:83) the pool of participants for this study was not sufficiently large to permit
random sampling procedures. Therefore participants were chosen ‘purposefully’
. This is
a strategy to choose small groups or individuals most likely to be knowledgeable and
informative about the phenomena of interest (McMillan & Schumacher 1993:413). The
criteria used for selection are outlined below.
The participants were selected on the basis of their position and length of
service in that
position. They were all female heads of academic departments who had been in the
position for at least two years. For the focus group interview, participants were selected
from a similar pool to that which completed the questionnaire. Care was also taken to
ensure that heads of traditionally male oriented disciplines were included. Two groups of
HoDs participated in the study, N= 9 in the VConf-FGI and N= 23 in the survey. Only 1
woman participated in both the survey and the interviews.
In the survey the role of the researcher was to distribute questionnaires
via overland-
post, conduct follow ups and check on non-respondents.
4.4.2.3 Locating participants
In South Africa, the participants were drawn from retained universities, namely those
which were not merging with other universities. The four universities selected in South
Africa comprised a traditionally English one;
a traditionally Afrikaans one; an African
one and one traditionally Coloured/Indian. Participants were first located through
telephone contact with the human resources department of the relevant institution. Once
contact with the prospective participant was established, a brief telephone interview was
conducted to screen her. Thereafter she was informed that an email would follow with
more details concerning the research. When all the prospective participants had been
screened by telephone, a list was drawn up including their relevant details.
This list was

then carefully scrutinised to determine which of the prospective participants was suitable
for the survey. Once the selection was made, the prospective participants were contacted
by email and/or by telephone.
