Abstract

The university alumni association is the venue for people with ties to the university to form and maintain collegiate relationships and address other persons' concerns. In particular, graduates maintain their relationships with the university and friends made there and exchange information to enhance their personal lives by participating in the university alumni association. The association even produces business opportunities for university graduates.
Against this background, the university alumni association is now acknowledged as an important societal organization. However, previous academic studies have rarely examined the characteristics of university alumni associations that have social value quantitatively, perhaps because it was difficult for external researchers to examine relationships and interactions between university alumni participants quantitatively.
This study was focused on the relationships (network) between university alumni association participants; the aim was to examine the characteristics of university alumni associations quantitatively. Specifically, university alumni association yearbooks were used in this study, and the topic providers for the alumni associations were identified. The aim was to examine the strength of social bonds among participants and topic providers quantitatively.
The survey covered 96 alumni association meetings held over a period of about 10 years (December 1957–August 1967) for a particular grade at Waseda University. The Waseda University Alumni Association publishes a publicly available alumni yearbook. The alumni associations for the grade surveyed in this study were the ones for which we were able to collect long-term, non-deficient data that allowed us to conduct a network analysis.
The analysis was carried out according to the following procedure. First, the strength of the quantitative ties between participants at each meeting was calculated based on the date and time of the meeting and participant information in the meeting records published in the alumni magazine. Next, the topic providers for each meeting were identified based on the information provided in the meeting records, and the strength of the ties between each provider and the other participants was calculated quantitatively.
The results of these analyses revealed the following. First, the strength of the ties between participants at each meeting of the Waseda University Alumni Association was mostly weak. Second, the strength of the ties between the topic provider and other participants at each meeting was weaker than the ties between the other participants.
These results indicate that the university alumni association meetings as a whole were attended by participants with weak ties, and the topic presenters at the meetings had very weak ties with the participants.
