The purpose of this paper is to examine the formation of strategic networks between second-tier actors in the context of a construction megaproject. The research question addressed is: How do second-tier strategic networks form in high uncertainty projects?

This is a qualitative single-case study, which examines strategic network formation in the context of a nuclear power plant construction project. Focused interviews with parties involved or having an interest in the megaproject were used as the primary data collection method.

The conditions for network formation in a megaproject context are specified with a focus on the determinants of uncertainty. A total of six second-tier network types with different formation conditions and potential roles in the project are characterized.

Analyzing the prerequisites of strategic network formation and examining the characteristics of various networks (that are either planned, taking shape or existing between the companies) in this specific context creates a basis for further study of network formation over network levels.

The formation of strategic networks is critical for many actors in the construction and related industries who are willing to participate in large projects. With the help of our findings, managers are able to define opportunities to orchestrate early phase network formation processes in uncertain circumstances, such as megaprojects.

The contribution of this paper lies in the close examination of strategic network formation from the second-tier actor perspective under circumstances of high uncertainty related to the early phases of megaprojects. Likewise, the illustration of different types of evolving nets in different phases of uncertain projects offers a contribution to the present discussion on strategic nets.

This study aims to investigate the influence of inventors’ abilities to acquire external knowledge, provide broad and professional knowledge and patenting output (i.e. different types of inventors) on the formation of structural holes.

The authors collected 59,798 patents applied for and granted in the USA by 33 of the largest firms worldwide in the pharmaceutical industry between 1975 and 2014. A random-effects tobit model was used to test the hypotheses.

The inventors’ ability to acquire external knowledge contributes to the formation of structural holes. While inventors’ ability to provide broad knowledge positively affects the formation of structural holes, their ability to provide professional knowledge works otherwise. In addition, key inventors and industrious inventors are more likely to form structural holes than talents.

The results identify individual factors that affect the formation of structural holes and improve the understanding of structural hole theory. This study is unique in that most scholars have studied the consequences of structural hole formation rather than their antecedents. Studies on the origin of structural holes neglect the effect of inventors’ knowledge abilities and patenting output. By addressing this gap, this study contributes to a more comprehensive theoretical understanding of structural holes. The results can guide managers in managing structural holes in accordance with inventors’ knowledge abilities and patenting outputs, which optimize the allocation of network resources.

The purpose of this paper is to explore the role of organisational capabilities (dynamic and operational) in the formation of value networks in the context of public transport services.

The theoretical argument is substantiated with qualitative data from four narratives on value network formations in the Swiss public transport system. These four narratives cover two types of new value networks: incremental improvements in established value networks; and radical leaps in emerging value networks.

These two types of new value networks entail the co‐evolution of different dynamic and operational capabilities.

The study is limited by the qualitative research approach.

Public transport operators can utilise the findings on organisational capabilities to guide incremental improvements in their existing value network and/or radical leaps into an emerging value network.

Governments should not only seek to increase transport capacity, but also aim to develop value networks to enhance public transport service experiences.

The paper applies value‐network thinking to public transport services. It offers a comprehensive framework to help organisations manage the formation of value networks. The results provide testable propositions that can be used to guide future research.

Social networks provide the architecture to facilitate important socio-emotional and task related exchanges within groups. However, researchers have just begun to explore how relationships form in groups comprised of individuals who differ on one or more dimensions. This paper investigates the role of social categorization and social network theories on the formation of social networks within diverse groups. We suggest that each perspective offers an alternative, but incomplete, understanding of how relationships may arise in diverse groups. Specifically, we integrate these two perspectives to provide a more complete understanding of how different types of diversity impact tie formation and allow individuals in diverse groups to achieve their socio-emotional and task-related objectives.

Policymakers often mandate and regulate the network formation to tackle complex issues of public interest. However, the imposed legal, procedural, and political constraints (i.e. mandated specifications) can affect the structuring and functioning of these networks and thus the sustainability and effectiveness of the collaboration over time. The purpose of this paper is to investigate how mandated specifications affect the formation of public networks.

Four networks of healthcare providers were selected and studied from the inception of the collaboration until the services’ activation, focusing specifically on how mandated specifications (i.e. mandated purpose, mechanisms for access to resources, structure, and timing) affected their processes of formation.

The cases show that mandated purpose facilitates goal alignment within the networks. The leeway granted to the actors for access and internal distribution of resources enhances the network flexibility, if appropriate monitoring against opportunism is applied. If structuring requirements are too stringent and the actors are forced to respect timing constraints that go against the organic evolution of internal relationships, the network capability to adapt and solve conflicts could be jeopardized.

Based on the findings, the authors formulate four propositions about the impact that mandated specifications have on the process of network formation, which policymakers should be aware of, when deciding to instigate a network.

As the foundation of social and economic development, infrastructure development projects are characterized by large initial investment, high technical requirements and thus generally delivered through complex contractor–subcontractor collaboration chains. This study aims to characterize the complexity of collaborative networks between contractors and subcontractors for infrastructure development through comparing the structural characteristics and the formation mechanisms of contractor–subcontractor collaborative networks for the following two different types of infrastructure: public works (PWCN) owned and operated by government agencies, and public utilities (PUCN) owned and operated by nongovernment agencies.

Based on the method of stochastic actor-oriented models and the longitudinal dataset of National Quality Award Projects in China during 2001–2020, this study compares how the structural characteristics of project-based collaborative networks between contractors and subcontractors for the two types of projects are different and how related micro-mechanisms, including both structure-based endogenous network effects and attribute-based exogenous homophily effects (institutional, organizational and geographical homophily), collectively underpin the formation of the networks.

The empirical results provide evidence that while the two networks are both characterized by relatively low levels of network density, PWCN is more globally connected around a minority of superconnected contractors as compared with PUCN. The results further reveal that compared with PUCN, the formation of PWCN is more significantly related to the structure-based anti in-isolates effect, suggesting that PWCN is more open for new entrant subcontractors. With regard to the attribute-based homophily effects, the results provide evidence that while both significantly and positively related to the effects of organizational (same company group) and geographical homophily (same location), the formation of PWCN and PUCN is oppositely driven by the institutional homophily effect (same ownership type).

As an exploratory effort of using network perspective to investigate the formation mechanisms of contractor–subcontractor relationships in the infrastructure development domain, this study contributes to a network and self-organizing system view of how contractors select subcontractors in different types of infrastructure projects. The study also provides insights into how contractor–subcontractor collaborative relationships can be better manipulated to promote the development of complex infrastructure in different contexts.

The purpose of this paper is to provide a micro-level, human-activity-centred interpretative framework for the way operations strategy is formed, linked and aligned with corporate-level strategies, and to apply it to gain insights on these processes.

Relying on the theoretical foundations of social practice theory and actor-network theory, as well as on the analysis of the organisational realities of the operations strategy formation process embedded in pluralistic organisational contexts, a conceptual framework for analysing the production and alignment of operations strategy is developed. The framework is then used to guide field research for the analysis of an operations-led strategic initiative in a medium-sized agro-food company.

Operations strategy formation can be interpreted as an ongoing practical, distributed social activity of network (re)formation. Specific initiatives, or events, act as catalysts for the association of operations strategy formation practices with corporate-level ones, facilitating thus the current and future alignment of strategic content. Artefacts play an active role in the linking process.

The research presented in this paper is pioneering as it is the first explicit consideration of operations strategy formation (process) as practical social activity (practices are the focus of analysis, not individuals’ choices), in which non-human agency (informational artefacts, etc.) is explicitly taken into account. For this purpose, a novel analytic framework was developed, which, however, need to be further tested to determine the exact conditions under which it is valid.

The framework improves the understanding of the organisational dynamics of operations strategy formation, its linking with, and institutionalisation in, other organisational processes and strategic discourses. Thus, it can assist in the analysis of operations-led strategic initiatives.

Application of the results obtained can provide better workplaces.

For the first time: operations strategy formation is considered as a social activity by focusing on the strategists and managers’ practices; the role of documents, decision-support tools and other artefacts is surfaced; and the importance of introducing operations strategy formation practices carrying strategy content into corporate and business-level strategy processes and their role in the alignment of the two strategies is emphasised.

To utilize Bluetooth as a layer 2 multi‐hop subnet for global IP network, there are two missing protocols in current Bluetooth stack: network formation and routing. In this paper, we propose our network formation and routing protocols optimized for such Bluetooth subnset usage scenarios to fill this gap. In this paper, we first present some observations on performance degradations of Bluetooth PAN due to network topologies and topology change when radio independant protocols are implemented. And then we analyze the reason of performance degradation. Based on our analysis, we first propose a flexible scatternet formation algorithm under conference scenario for multi‐hop communication. By using proposed method, scatternet can be formed flexibly with star, mesh, or linked line based on several parameters like number of maximum piconets that a gateway Bluetooth device can participate, and whether loops are needed in the resulting scatternet to achieve better network performance. To utilize topology information in multi‐hop communication, we propose a Cross‐layer Optimized Routing for Bluetooth (CORB) CORB is a QoS‐extended AODV routing protocol with mainly two optimizations between networking layer and underlying Bluetooth MAC layer. The first optimization is to use a new load metric. (LM) in QoS routing protocol instead of number of hops in conventional best effort routing. LM is derived from estimation of nodes’ link bandwidth, which reflects the different roles of nodes in Bluetooth scatternet. This proposal helps routing protocol to bypass heavily loaded nodes, and find route with larger bandwidth. The second optimization is to adjust LM and some MAC layer parameters in response to the unstable network topology caused by movement and change of indoor radio condition. Finally, We present some simulation and experiment results based on implementation, which prove the effectiveness of our protocols.

The evolution of interorganizational networks is shaped by micro and macro processes. At the micro level organizational dyads negotiate relationships in light of their own cost—benefit analysis. At the macro level resources flow through networks and are mobilized by coalitions. Current research is beginning to examine integrating mechanisms which link network dynamics to dyadic relationship formation. In this paper we examine interorganizational brokerage as an integrating mechanism linking micro and macro network processes. We focus on the formation of networks in the global television industry. The Children's Television Network (CTW) has licensed and co‐produced its flagship program “Sesame Street” in many countries around the globe. Recently, it has expanded beyond a strategy based on direct first‐order linkages to one of brokerage and interorganizational entrepreneurship, entailing the formation of second‐order linkages—linkages between organizations with which CTW has direct first‐order relationships. In the aftermath of the Oslo Peace Agreement, CTW acted as a broker and sponsor of a joint venture between Israeli and Palestinian broadcasters. The main challenge facing CTW was a high degree of distrust between the parties motivated by fears of opportunistic exploitation. Such fears typically result in high transaction costs, making joint venture formation difficult, if not impossible. In its capacity as broker, CTW worked to reduce transaction costs. This was done by providing resources where needed, and by facilitating interaction and trust building between the parties. We describe CTW's tactics during the formation of this joint venture, and we analyze the outcome of the joint venture from the point of view of CTW's overall strategy. We conclude by discussing CTW's network and brokerage strategy in the aftermath of the joint venture.

This chapter investigates the origins of cross-sectoral collaboration by exploring when and why policy networks form within the Turkish health sector – a least likely case for network formation. The analysis presented here draws on information collected from a number of official documents, semi-structured interviews with professional experts, and two multi-stakeholder meetings. Timewise, networks entered the policy jargon during the introduction of the Health Transformation Program in 2003. Yet, the years between 2011 and 2015 were ground-breaking in producing concrete cross-sectoral collaborative instruments of policy making. The findings of the analysis reveal that policy networks form as a result of central government’s choice to devolve responsibility and expand the policy space with new issues and actors. Moreover, policy networks emerge not only during the times of policy change which has a reactionary, abrupt, and nature but also during the times of policy stability and legitimacy. These contextual factors are crucial in maintaining an atmosphere of trust among stakeholders, particularly between state and non-state actors. The refugee crisis and spreading securitization discourse in the post-2015 period explain the shifting policy and political agenda leading to public sector retrenchment from cross-sectoral projects within the field of health. This chapter intends to contribute to the literature of comparative public policy by examining the link between policy networks and policy change in addition to adding to the debates on network governance by exploring the processes of network formation. Finally, this chapter contributes to Turkish studies by examining the process of network formation within the Turkish health sector.
