1. 三隅 一人(本名:一百), Trust in Community and Free Rider, 3rd ISA Forum of Sociology, 2016.07, Trust is believed to contribute on escape from the free rider problem. However, considering the discussion based on threshold models of social dilemmas, if we assume that an actor’s cognitive threshold for cooperating is related with trust, it is possible to say that trust should enhance free rider. This is because an actor will be more likely to stay as a free rider (namely, to have a high threshold) when they trust in community for its ability to provide public goods. Trust of this kind is close to trust in abstract systems, and as Giddens suggests, it is based on trust in interpersonal relationships. Then, we need to explore how trust in community and general trust are related to each other, and how these two kinds of trust determine people’s cooperative behaviors. Considering the case of residential community and utilizing survey data, in this study we make an empirical approach to these questions. At first, by conducting principal component analysis for the variables like neighborhood evaluations and trust at the municipality levels, we extract two components: trust in community and residential attachment. We additionally extract two components through the similar analysis for the variables relevant to participation in community events; voluntary participation and free riding participation. (The latter indicates participation only in joyful events.) Multiple-regression analysis shows while trust in community strongly determines voluntary participation, it also enhances free riding participation. In both cases, the effects of general trust seem to be observed in the effect of trust in community. Thus our results suggest that general trust and trust in community are not necessarily complementary to each other in order to enhance community participation, and that trust in community could strengthen both cooperation and free riding at the same time. We will further discuss the meaning these paradoxical results imply. .
2. 三隅 一人(本名:一百), Net-base Theory of Social Capital, International Sociological Association (18th World Congress of Sociology), 2014.07, The concept of social capital has been widely accepted; however its theoretical significance in sociology is not clear yet. In this paper, we propose a theoretical device in order to make this analogical concept the key to integrate relation-theories (theories of social relation, social networks, and social structure) in sociology. Social capital is analogy, the aim of which is to capture such mechanism that is similar to capital accumulation process in social structure. Every element of social structure and every relation-theory as well should have relation to this concept to some degree. As a rule it inevitably has multiple meanings; on the other hand, it should work as a hub by which various relation-theories are consistently connected to each other. In order to extract this unifying power, we introduce the ‘net-base.’ Net-base is a common attribute that provides a basis of social ties. Thus net-base implies a corresponding socio-centric network that consists of all the members who share it; moreover, configuration of various net-bases implies interrelationship between multiple socio-centric networks. We assume that accumulation of social capital is oriented by socio-centric networks embedded in social structure; then, net-base is an indicator in terms of which we can infer how network mechanisms in social structure condition the accumulation process of social capital. In making the inference we often need to access different type relation-theories, which will provide an opportunity of theory integration. Additionally, net-base is easily measurable by questionnaires on personal networks and group participation in ordinal individual-base survey. Thus, net-base theory makes it possible to locate ‘social capital’ in the storage house of relation-theories and to empirically find valid inference in regard to network mechanisms of capital accumulation. More extendedly, it should have integrity with the rational choice research program of social capital proposed by Flap and Völker (2004)..
