There has been an extensive range of social capital literature. I'd suggest you focus on the works that explicitly discuss the impacts that social capital has on social cohesion. Note there are different varieties of social capital, and you might want to distinguish their roles.

Hi Letta,

First, it is hard to understand your conceptual framework. To me, a conceptual framework is a model CONNECTING key concepts TO demonstrate some sort of arguments towards a topic/research objectives. A conceptual framework therefore is quite unique to each study. You just LISTED your key concepts, not forming a framework yet.

Second, as defined above, your objectives which is conceptualised from your topic, must pose the problem to your conceptual framework to be solved. In other words, your conceptual framework should contain your hypotheses in relation to your research questions/objectives. Therefore, you base on your objectives to identify which theory should fit into your framework.

Third, regarding your three objectives, the social capital theories may be relevant, but I am not sure this theoretical tradition would be as important as other traditions such as sustainable cooperatives, etc. in helping you explain/answer those questions.

Best,
