“…10 One possible interpretation for p is that it indicates the effect of alters (/') on ego (/) through the social network (Bovasso, 1996;Burt, 1987). This might occur through the process of cohesion, in which people influence one another by sharing information or persuasion (Barnes, 1972;Blau, 1977;Bott, 1971;Collins, 1981;Festinger, 1950;Homans, 1950;Mitchell, 1973), or through structural equiva lence, where the w ü indicate the role that people occupy and the y¡ represent a behavior that is a function of the behaviors of others who occupy similar roles (Burt, 1987;Merton, 1957;Nadel, 1957;Radcliffe-Brown, 1940). For example, cohesion applies when students' educational decisions and aspirations are influenced through direct discussions (Davies & Kandel, 1981;Duncan, Haller, & Portes, 1968;Hartup, 1978;Sewell, Haller, & Ohlendorf, 1970).…”
