This paper is concerned with online communication of apartment buildings' residents on general purpose social networking site (SNS) VKontakte (VK), focusing on how groups' participants use instruments of SNS to separate place-based discussions and participation in wider community initiatives. With the help of topic modeling algorithm LDA, we analyzed posts collected from online groups related to apartment buildings in St. Petersburg to reveal differences in communication in open groups and restricted access groups. We also looked at overlaps between local groups of apartment buildings and city-wide movements. Our study shows that inside SNS there is a functional differentiation between restricted access groups and open groups, which have different audiences and communicative strategies. Restricted access (private) groups play an important role in the formation of neighbors' communities of trust and, supposedly, can be useful substitutes of face-to-face interaction for people moving into new buildings. Open (public) groups function as public forums for fostering neighbors' cooperation and attracting the attention of the broader public to local issues and conflicts. JEL Classification: Z19.

This study investigates how the sociometric popularity of schoolchildren is related to individual academic achievements in a context of different levels of academic culture and educational aspirations in the classroom. The sample includes 5058 students in 270 classes from 98 schools in St. Petersburg. To examine class-level effects, we employ multi-level hierarchical models using HLM 7 software. Different effects for boys and girls were found, indicating that the relationship between academic performance and popularity is gender-specific. The results demonstrate that in classes with a low learning motivation individual academic achievements of boys are negatively related to their popularity, while in classes with a high academic culture the relationship is positive.
