frequent contact with person j, or person j indicated that they had frequent contact with person i<br />

cell entry Xij in the frequent contact matrix was 1.<br />

Strong Friendship Ties. The next step was to compute the strong friendship matrix. In<br />

the reciprocated ties <strong>analysis</strong>, the strong friendship matrix was computed by multiplying the<br />

frequent contact matrix and the friendship matrix which contained only reciprocated friendship<br />

ties. In the non-reciprocated ties <strong>analysis</strong>, the strong friendship matrix was computed by<br />

multiplying the frequent contact matrix and the friendship matrix which included all ties<br />

regardless <strong>of</strong> whether or not they were reciprocated. The same procedure was utilized to create<br />

all other network ties assessed in this study as well.<br />

As is the case in most <strong>social</strong> networks research, all network measures were assessed<br />

using a single measure. This is typical because assessing each type <strong>of</strong> tie with multiple measures<br />

would be time-consuming and impractical for respondents. If each network was measured using<br />

multiple items, each respondent would have had to respond to multiple items for each network<br />

and for each <strong>of</strong> 137 other employees. A drawback to single-item measures is that they do not<br />

allow for the assessment <strong>of</strong> reliability, but our methods (roster, recurring ties) allows for the<br />

highest possible reliability (Marsden, 1990).<br />

Control Variables<br />

In addition to the independent variables, information on tenure, gender and leadership<br />

positions held was collected to rule out other possible explanations for results. Similarity<br />

matrixes were constructed for each <strong>of</strong> these variables and utilized in the <strong>analysis</strong> 2 .<br />

2 Quadratic Assignment Procedure <strong>analysis</strong> requires that similarity with respect to<br />

variables, not the absolute value <strong>of</strong> the variables, be utilized (See Umphress et al., 2003).<br />
