Regarding complex networks, one of the most relevant problems is to understand and to explore community structure. In particular it is important to define the network organization and the functions associated to the different network partitions. In this context, the idea is to consider some new...

We investigate the computational complexity of several decision problems in hedonic coalition formation games and demonstrate that attaining stability in such games remains NP-hard even when they are additive. Precisely, we prove that when either core stability or strict core stability is under...

Do quality at entry assessments enhance the delivery of development projects? In this paper we take advantage of approval and execution systems in place at the Inter-American Development Bank (IDB) to examine whether projects that have higher quality at entry-captured through grading scores...

India is seen as a key developmental partner to Nepal with the latter being one of the first receipts of development aid from India. Development aid from India to Nepal has not only been associated with creation of infrastructure in the country but also with human capital development and...
