“…Krackhardt (1992) provided that strong ties enable individuals to access valuable information easily. Lai and Wong (2002) suggested that information is more likely to spread at the strong rather than weak ties. Therefore, corporate organizations within the social network tend to be similar since they are more likely to decide and behave based on the common information.…”

The aim of this study is to provide a theoretical framework concerning how firms exert isomorphic pressures to survive and thrive in the existing market. In addition to the institutional strategies (Lawrence, 1999), the authors clarify the relationship among isomorphic pressures from firms, the value of firm resources, and sustainable competitive advantage. For this purpose, this paper reviews institutional isomorphism and relevant theories like resource based view, transaction cost theory, and resource dependency theory. It then provides propositions based on theoretical reviews and inferences. Firms are expected to strengthen their resources by exerting various isomorphic pressures: coercive, mimetic, and normative. Therefore, they are more likely to beat competitors even in the existing markets. The implications are discussed at the end of the paper. First of all, this study provides an extension to the horizon of institutionalization strategies by providing an additional viewpoint. In addition, it enlightens the importance of firm strategies based on corporal isomorphic pressures. Practitioners are recommended to consider their firms' ability to conform other stakeholders as a significant strategic asset.

“…Recently, the availability of automatically saved data makes it possible to quantitatively analyse the role of tie strength in huge-size social networks. For example, the strength of a tie can be measured by the cumulative time spent in telephone communication in a time period [26,36]. And the concept of weak ties has been applied in many http://doc.rero.ch branches of science beyond the social-network analysis, such as the biological science [27] and the information science [37].…”

“…And the concept of weak ties has been applied in many http://doc.rero.ch branches of science beyond the social-network analysis, such as the biological science [27] and the information science [37]. Although the majority of previous works focused on the role of weak ties on dynamics, such as the information flow [38], rumor spreading [36] and knowledge transfer [39], some recent works suggested that the weak ties also play a key topological role, like to maintain the connectivity of a network [26] and to affect the emergence of community structure [40]. In contrast to the above-mentioned works, the definition of the tie strength in this letter is not limited to social science or to a specific method.…”

Link prediction in weighted networks: The role of weak ties

2010

-Plenty of algorithms for link prediction have been proposed and were applied to various real networks. Among these algorithms, the weights of links are rarely taken into account. In this letter, we use local similarity indices to estimate the likelihood of the existence of links in weighted networks, including Common Neighbor, Adamic-Adar Index, Resource Allocation Index, and their weighted versions. We have tested the prediction accuracy on real social, technological and biological networks. Overall speaking, the resource allocation index performs best. To our surprise, sometimes the weighted indices perform even worse than the unweighted indices, which reminds us of the well-known Weak-Ties Theory. Further experimental study shows that the weak ties play a significant role in the link prediction, and to emphasize the contributions of weak ties can remarkably enhance the prediction accuracy for some networks. We give a semi-quantitative explanation based on the motif analysis. This letter provides a start point for the possible weak-ties theory in information retrieval.
