Taking into account both competence and governance issues, and six dimensions of tie strength, this article argues that in networks for exploration there are good reasons, counter to the thesis of the 'strength of weak ties', for a dense structure of ties that are strong in most dimensions.By...

In this article we provide an empirical illustration of hypotheses, developed in the literature, on the role of density and strength of ties in innovation networks.We study both exploration and exploitation networks in the Dutch multimedia and pharmaceutical biotechnology industry.We find...

This paper uses a cognitive theory of firms and organizations, with a focus on learning and innovation.Here, cognition is a wide notion, including value judgments and corresponding feelings and emotions.This paper focuses on the relation between that cognitive theory and Penrose's theory of the...

This chapter offers a theory and an analytical framework for the analysis of cluster dynamics, i.e. the innovative performance and evolution of clusters.It develops three types of embedding: institutional embedding, structural embedding (network structure), and relational embedding (type and...

This article provides empirical tests of the hypothesis of optimal cognitive distance , proposed by Nooteboom (1999, 2000), in two distinct empirical settings.Variety of cognition, needed for learning, has two dimensions: the number of agents with different cognition, and differences in...

The literature on entrepreneurship recognizes a variety of entrepreneurial roles, and the question arises what roles are played when and by whom.In this article, roles are attributed to different stages of innovation and organizational development.A central theme is the relation between...

This paper contributes to the analysis of where and how both exploitation and exploration may take place inside and between communities and organizations. It connects with the discussion of differences between communities of practice and epistemic communities. The analysis allows for differences...

This chapter explains and employs a constructivist, interactionist theory of knowledge that has come to be known as the perspective of 'embodied cognition'. That view has roots in earlier developmental psychology, and in sociology, and more recently has received further substance from neural...

This paper gives a survey of insights into inter-firm alliances and networks for innovation, from a constructivist, interactionist perspective on knowledge, which leads to the notion of 'cognitive distance'.It looks at both the competence and the governance side of relationships.Given cognitive...
