A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and...

This paper investigates the determinants of co-inventor tie formation using micro-data on genomic patents from 1990 to 2006 in France. In a single analysis, we consider the relational and proximity perspectives that are usually treated separately. In order to do so, we analyse various forms of...

This paper carries out an empirical investigation into the causal relationships connecting four types of social capital (i.e. bonding, bridging, linking, and corporate), and three forms of trust (horizontal, meso, and vertical), in a community of entrepreneurs located in the Italian industrial...

The present paper proposes a new way of thinking regarding the relation between innovation and knowledge using a Physics-borrowed model, trying to prove whether knowledge resources can „flow” (be percolated) in a network or a grid, in order to be transformed in technological innovation. In...

In its first part, the present paper demonstrates the relation between innovation and knowledge using a literature review. Concepts such as technology, technological innovation, knowledge and knowledge flow are defined and described. The Newman model of knowledge flows is then used as a starting...

Research and Science Today Journal is a publication founded in 2011 and it is dedicated to the students of all levels (license, master and doctoral) of faculties in the country and abroad. We want to offer the participants the opportunity to present their scientific works in the following areas:...

Using a unique dataset collected in 59 rural Gambian villages, we study how ethnic heterogeneity is related to the structure of four economic exchange networks: land, labor, inputs and credit. We find that different measures of village-level ethnic fragmentation are mostly uncorrelated with...

A unique dataset of social and economic networks collected in 60 rural Gambian villages is used to study the ways in which households with links outside the village (that are considered as a proxy for market connections) behave in the locally available exchange networks for land, labor, input...

Using a unique dataset collected in 60 Gambian villages, I study six social and economic networks: (i) land exchange, (ii) labor exchange, (iii) tool and fertilizer exchange, (iv) credit exchange, (v) matrimonial relationships and (vi) kinship relationships. A variety of measures gleaned from...
