Finding hidden hierarchy in social networks
(2016-06) Kurt, Süreyya Emre
Stratification among humans is a well studied concept that significantly impacts how social connections are shaped. Given that on-line social networks capture social connections among people, similar structure exist in these networks with respect to the presence of social hierarchies. In this thesis we study the problem of finding hidden hierarchies in social networks, in the form of social levels. The problem is motivated by the need for stratification for social advertising. We formulate the problem into dividing the users of a social network into levels, such that three main metrics are minimized: agony induced by the reverse links in the hierarchy, support disorder resulting from users in higher levels having less impact, and support imbalance resulting from users in the same level having diverse impact. We developed several heuristic algorithms to solve the problem at real-world scales. We present an evaluation that showcases the result quality and running time performance of our algorithms on real-world as well as synthetically generated graphs.

Overlapping institutions on the way to non-hierarchy: EU-NATO relations between 1993-2016
(2021-08) Sözen, Ahmet
This study aims to analyze the dynamics of cooperation and competition between the EU and NATO between 1993 and 2016. Specifically, this research evaluated the dynamics of cooperation and competition between the EU and NATO within the scope of functional overlapping and hierarchy, which are basic dimensions of the regime complex theory developed in the first ten years of the 21st century. The study shows that the EU and NATO jointly operate in the field of military crisis management policy. At the same time, the study argues that although there is a hierarchy in favour of NATO between the EU and NATO, this hierarchy has decreased over time. This thesis states that both cooperation and competition dynamics can be seen between the two organizations because the EU and NATO operate jointly in military crisis management policy area. However, based on the decreasing hierarchy between EU and NATO, this thesis argues that the relationship between the two organizations is on the way from cooperation to competition.
