“…In terms of content, the network can contain peers, "step-ahead" peers, or supervisors (Ensher, Thomas, & Murphy, 2001). For example, mentoring may involve a peer group, such as when women scientists convene to talk about the science community (Davis, 2001). A network can also refer to "cascade mentoring," a popular group form in science education circles, where a professor may supervise graduate students or advanced undergraduates in research, who in turn supervise lower-division undergraduates (e.g., Davis, Ginorio, Hollenshead, Lazarus, & Rayman, 1996).…”
