egarding POS than do more traditional employees. For that reason, the generalizability <strong>of</strong> the<br />

results <strong>of</strong> this study may be limited.<br />

Another limitation <strong>of</strong> this study is that it did not explicitly measure the <strong>social</strong> information<br />

processing, <strong>social</strong> comparison and <strong>social</strong> learning perspectives that were utilized to build<br />

theoretical linkages. While similarity in perceptions is a commonly used outcome for <strong>social</strong><br />

network studies testing a <strong>social</strong> information processing model (for examples, see Ibarra &<br />

Andrews, 1993; Umphress et al., 2003), few network studies have assessed <strong>social</strong> comparison.<br />

Those that did (Shah, 1998; Ho, 2003) explicitly asked employees whether or not other<br />

employees were utilized as <strong>social</strong> referents for the dependent variables <strong>of</strong> interest. For instance,<br />

in examining employee perceptions <strong>of</strong> psychological contract fulfillment, Ho (2002) asked<br />

employees with which other employees they discussed perceptions <strong>of</strong> psychological contract<br />

fulfillment. Similarly, few if any network studies have assessed <strong>social</strong> learning as an outcome<br />

variable. In fact, one <strong>of</strong> the only studies directly assessing a <strong>social</strong> learning perspective<br />

examined similarity in performance <strong>of</strong> <strong>organizational</strong> citizenship behaviors in a workgroup as an<br />

outcome variable (Bommer et al., 2003). However, because the outcome variables <strong>of</strong> <strong>social</strong><br />

information processing, <strong>social</strong> comparison and <strong>social</strong> learning are usually similarity with respect<br />

to an attitude or behavior, it is difficult to separate the effects <strong>of</strong> each <strong>social</strong> <strong>influence</strong> process in<br />

a given study.<br />

Future Research<br />

This dissertation presents a number <strong>of</strong> opportunities for future research. First, while this<br />

study explored the role that a number <strong>of</strong> different ties play in influencing employees’ POS, it<br />

likely that other network ties may also <strong>influence</strong> employees’ POS. For instance, Sparrow et al.<br />

(2002) investigated the role that hindrance networks play in organizations. They found that<br />
