instance, a researcher may find a positive relationship between friendship ties and other<br />

individuals’ perceptions <strong>of</strong> an individual’s power, but not measure advice ties in their <strong>analysis</strong>.<br />

The <strong>perceived</strong> power <strong>of</strong> the individual may actually have little to do with friendship ties and may<br />

be the result <strong>of</strong> the advice ties that the individual maintains. Therefore, it important to assess<br />

different types <strong>of</strong> ties to determine which are related to a dependent variable (Ibarra, 1993).<br />

When tie content is considered, <strong>social</strong> networks researchers usually distinguish between advice<br />

and friendship ties (Ibarra & Andrews, 1993).<br />

Advice Ties. Employees share information and knowledge related to the completion <strong>of</strong><br />

their work through advice ties (Ibarra, 1993). Such ties are characterized by cognitive trust, or<br />

the belief that another has the ability and competence to provide help (McAllister, 1995; Ho,<br />

2002; Ho, Levesque, & Rousseau, 2003). Therefore, asking an individual for advice is an<br />

indication <strong>of</strong> respect for the opinion <strong>of</strong> that individual and an expectation that help from that<br />

individual is available and useful.<br />

The provision or exchange <strong>of</strong> advice is related to important outcomes in organizations.<br />

Employees who frequently provide advice to others are <strong>of</strong>ten <strong>perceived</strong> as being more powerful<br />

than individuals who are not a frequent source <strong>of</strong> advice (Brass, 1984; Brass & Burkhardt, 1993;<br />

Burkhardt & Brass, 1990; Knoke & Burt, 1983) because others are dependant on them for<br />

information needed to complete their jobs (Brass & Burkhardt, 1993). A study by Sparrowe,<br />

Liden, Wayne, and Kramer (2001) showed that employees who provided more advice to their<br />

coworkers received more favorable performance evaluations from supervisors. Settoon and<br />

Mossholder (2002) showed that individuals with more advice relationships were more likely to<br />

perform citizenship behaviors for their coworkers.<br />
