This study aims to evaluate the network robustness of major Asian airlines and to explore which airport types have the greatest impact on robustness. We also analyze airports’ specific brokerage roles and their impacts on the robustness of the entire air route network. We select 10 major Asian full-service airlines that operate the main passenger terminals at the top-ranked hub airports in Asia. Data is collected from the Official Airline Guide passenger route dataset for 2017. The results of the network robustness analysis show that Air China and China Eastern Airlines have relatively high network robustness. In contrast, airlines with broader international coverage, such as Japan Airlines, Korean Air, and Singapore Airlines have higher network vulnerability. The measure of betweenness centrality has a greater impact on the robustness of air route networks than other centrality measures have. Furthermore, the brokerage role analysis shows that Chinese airports are more influential within China and Asia but are less influential globally when compared to other major hub airports in Asia. Incheon International Airport, Singapore Changi Airport, Hong Kong International Airport, and Narita International Airport play strong “liaison” roles. Among the brokerage roles, the liaison role has a greater impact on the robustness of air route networks.

This study aims to identify which actors play leadership and brokerage roles in voluntary environmental collaborations and how the corporate social responsibility (CSR) of actors is associated with such voluntary networking behaviours in Cambodia.

To achieve these purposes, this study mainly uses social network analysis to capture the properties of networking behaviours in the voluntary collaborative activities underlying three main environmental issues: waste disposal, energy and water pollution. The study focusses on the collaborative efforts undertaken by actors across multiple sectors: governmental organizations, for-profits and civil society organizations.

The results show that the government plays the leading role in voluntary environmental collaborations across environmental issues; however, the actual implementation is expanded to be undertaken by non-state actors. Moreover, CSR has positive associations with networking and brokerage roles; therefore, this study reveals the utility of various voluntary policy instruments.

This study demonstrates the role of governmental initiation and its influence on non-state actors, even for voluntary environmental tools. The CSR initiatives of private actors can also be supported and encouraged by the government, which will promote participation by private actors in voluntary collaborative networks and their leading role as network facilitators.

By understanding the positions and roles of each actor in the environmental collaborative networks, environmental policymakers can better understand the possibilities and the capabilities of each actor both to improve policy design and learning and to respond to policy changes effectively.

Voluntary collaboration and CSR are non-regulated policy tools; however, they can be promoted and introduced into society by governmental organizations, and they affect each other.

In the pursuit of co-exploration, the strength and brokerage dimensions of dyadic ties create a novelty–action trade-off: tie strength facilitates coordination but constraints novelty, while tie brokerage expands knowledge diversity but aggravates coordination difficulty. This study contributes towards a better understanding of this tension by comparing two dimensions of relational ties and examining their contingent values given different environmental factors and exchange characteristics.

The authors used survey data from 194 matched buyer–supplier dyads in China's high-tech industries and employed hierarchical moderated regression analysis to test the proposed hypotheses.

The authors find that compared with tie strength, tie brokerage has a stronger positive effect on co-exploration. Moreover, guanxi importance amplifies the effect of tie strength while decreasing the value of tie brokerage. As market uncertainty increases, the role of tie brokerage becomes more salient. Additionally, tie strength becomes less effective when buyer centralization is high, whereas tie brokerage exerts a stronger impact on co-exploration when an exchange is highly formalized.

This study contributes to the supply chain literature by adopting a relational perspective to integrate relational ties into the study of buyer–supplier co-exploration and by elaborating on the different implications of tie strength and tie brokerage in resolving the novelty–action trade-off. Furthermore, it provides a more nuanced understanding of when distinct dimensions of relational ties are effective, by clarifying boundary conditions in terms of environmental factors and exchange characteristics.

Health care ecosystems instantiate different innovation trajectories, driven either by science-/techno-push or user-centric rationales. This article focuses on organization intermediaries (OIs), respectively, active in health care ecosystems driven by science- and techno-push versus user-centric innovation processes; it aims at characterizing their operation and intervention modes. The analysis elaborates on network and content brokerage. Innovation also needs to consider various challenges associated with physical vicinity. The authors check whether territorial anchoring plays a role in brokerage, depending on the innovation model.

The article offers an investigation of eight French organizations matching the definition of OIs and active in different areas of health care-related innovation. It follows a qualitative and abductive research protocol adhering to the precepts of grounded theory.

First, the authors show that content and network brokerage specialize in specific activities in each innovation model. On network brokerage, the authors show that OIs foster the development of communities of practice in the science-/techno-push model, while they nurture communities of innovation in the user-centric model. Services materializing content brokerage are typical consequences of activities performed in each model. The second contribution deals with physical vicinity. In the science-/techno-push model, OIs install a physical space (the “internal” dimension) to support the development of communities of practice, while the “external” dimension copes with agglomeration effects. In the user-centric model, OIs deliver services thanks to the “internal” space; communities of innovation create a leverage effect on the physical space to operate their activities that are supported by “external” network effects.

The originality of the article lies in the description of the alternative roles plaid by organization intermediaries in the science-/techno-push versus user-centric approaches of innovation. In these two approaches, (contents and network) brokerage and physical vicinity play different roles.

This article explores the contingent role that social ties play in the emergence of status hierarchies. We argue that, while status is formed based on actors’ perception and understanding of social cues, network structure, and position influence this process by influencing the attention and legitimacy given to the focal actor in accordance with social cues that signal an actor’s identity. Using a large data set from an open-source software development community, we find that a broker linking diverse network members is less likely to receive status ratings from others and that the rating is more likely to be low when a broker receives a rating. Furthermore, we find evidence that the effects of brokerage are contingent upon certain factors that may affect the attention and legitimacy given to actors in the process of status evaluation, such as the actor’s prior status. An actor’s prior status was found to weaken the negative effect of brokerage. The importance of this study for theories of status, social networks, and attention is discussed.

A key element in the personalisation of health and social care is the upfront allocation of a budget to disabled and older people which they can use to obtain the supports they require. The benefit of this arrangement in increasing user choice and control will not materialise unless recipients can either acquire or access the skills of brokerage needed to plan and arrange their supports. The independent support broker is one important response to this need. However, the role needs to match the intentions of personalisation and avoid the undesirable characteristics that many social care users associate with the term ‘professional’. This raises specific questions about the definition of the role and training requirements of brokers, and broader themes which are explored with reference to the findings from two recent projects undertaken by the National Development Team for Inclusion. The second of these projects was commissioned by Skills for Care London, and led to a set of proposals for the training and accreditation of support brokers.

The purpose of this paper is to investigate whether real estate companies manipulate their earnings through the brokerage fee across ownership expropriation or not.

This study considers Kuala Lumpur Stock Exchange listed real estate firms to investigate how the brokerage fee in the real estate industry might affect the earnings management of firms across its ownership expropriation. Using annual report data, the authors investigate the associations over a panel for the period 2008−2012. Robust panel regression is used to divulge the probability values with reference by probit regression.

Overall, the results show that high brokerage fees would drive more events of earnings management and that, generally, the ownership concentration among Malaysian real estate firms significantly affects the earnings management of the firms.

This study shows that firm profitability and brokerage fees enhance the probability of firm’s earnings management. A low brokerage fee would reflect low revenue to the company. Therefore, management would opt to manipulate earnings in order to overstate earnings, which garners more interest from investors.

Real estate values in Malaysia have climbed steadily over the years due to a combination of reasons giving companies a higher brokerage fee. Earnings management has become a big issue for property investors. The study demonstrates the relationship between earnings management and brokerage fee across ownership expropriation which can be considered by shareholders in their own strategic planning and investors in their own investing.

Leadership is a social phenomenon. Therefore, it has to be examined according to its social context. The point to be underlined by the social context is the social network in which the leader emerges. Considering the studies, the social network side of leadership is relatively ignored comparing with sociometric studies. In that sense, the aim of this study is to reveal whether there is a relationship between the positions of the military personnel, who are defined as one of the gray-collar working groups in the literature, within the social network mechanisms of which they are members, and their self-leadership perceptions. To answer the question, a self-leadership scale was applied to 69 gray-collar employees working in a military unit and network analyses were performed. According to results, there is a strong, positive and significant relationship between the network mechanism centrality criteria indegree, reach centrality and closeness and the self-leadership perceptions of individuals. In addition, there was no significant relationship between eigenvector centrality and honest brokerage, which are among the network mechanism criteria, and the actors’ self-leadership perceptions. The study has aimed at accenting and adding different perspectives to the leadership studies and gray-collar literature.

Using the large database of patent, the purpose of this paper is to structure a technology convergence network using various patent network analysis for integrating different results according to network characteristics.

The patent co-class analysis and the patent citation analysis are applied to discover core safety fields and technology, respectively. In specific, three types of network analysis, which are centrality analysis, association rule mining analysis and brokerage network analysis, are applied to measure the individual, synergy and group intensity.

The core safety fields derived from three types of network analysis used by different nature of data algorithms are compared with each other to understand distinctive meaning of cores of patent class such as medical safety, working safety and vehicle safety, differentiating network structure. Also, to be specific, the authors find the detailed technology contained in the core patent class using patent citation network analysis.

The results provide meaningful implications to various stakeholders in organization: safety management, safety engineering and safety policy. The multiple patent network enables safety manager to identify core safety convergence fields and safety engineers to develop new safety technology. Also, in the view of technology convergence, the strategy of safety policy can be expanded to collaboration and open innovation.

This is the initial study on applying various network analysis algorithms based on patent data (class and citation) for safety management. Through comparison among network analysis techniques, the different results are identified and the collective decision making on finding core of safety technology convergence is supported. The decision maker can obtain the various perspectives of tracing technology convergence.
