This chapter provides a deep dive into knowledge networks. The authors provide an inclusive definition of a knowledge network. A knowledge network includes nodes as sources and targets of knowledge, relationships as knowledge links, and messages as knowledge transactions and flows. The authors note how knowledge networks differ from other types of networks, specifically their dynamic and chaotic state and continuous transactions. These peculiarities reflect the economic properties and behaviors of knowledge. The elements of networks described in Chapter 2 are elaborated for knowledge networks. The chapter calls out knowledge network domains, geographies, typologies, nodes, messages, and relationships.

This chapter focuses on the treatment and characterization of networks as an emerging discipline. Networks are defined. The authors call out and explain the importance of network domains, network geographies and topologies, network behaviors, network nodes, network links, relationships and flows, and network messages. While network sciences provide a strong foundation for research and analysis, the authors note the lack of knowledge networks. This chapter highlights the need to expand coverage to include knowledge networks.

The purpose of this paper is to develop a conceptual framework of severe expatriate crises focusing on the occurrence of “fit-dependent” crisis events, which is when the crisis is “man made” and triggered by expatriates’ maladjustment or acculturation stress in the host country. The authors focus on the causes, prevention and management of fit-dependent expatriate crises.

The authors develop a conceptual framework of fit-dependent expatriate crises that involves different levels of analysis.

The conceptual framework shows that crises can be triggered at micro, meso and macro levels ranging from the personal and family domains (micro), to the network and organisational domains (meso) as well as the host country domain (macro). The authors conceptualise these “domains of causes” as triggering maladjustment and acculturation stress that ultimately leads to a severe crisis event with correspondingly serious and potentially life-changing consequences. Furthermore, using a process perspective, the authors outline strategies for preventing and managing crises before, during and after the crisis occurs, discussing the support roles of various internal (organisational) and external (specialist) stakeholders.

Studying the link between expatriation and crises is a highly relevant research endeavour because severe crisis events will impact on HRM policies, processes and procedures for dealing with employees living abroad, and will create additional challenges for HRM beyond what could normally be expected. Using attribution theory to explain why organisational support and intervention to assist expatriates during a crisis is not always forthcoming, and theories of social networks to elucidate the “first responder” roles of various support actors, the authors contribute to the expatriate literature by opening up the field to a better understanding of the dark side of expatriation that includes crisis definition, prevention, management and solutions.

Although research has shown differences between self-initiated experiences and expatriation, this differentiation has rarely been made when it comes to more long-term global careers. The purpose of this paper is to identify similarities and differences between repeat expatriates and international itinerants in their career paths, subjective experiences, and narratives of how they relate to their context.

A narrative approach was used and interviews were conducted with ten repeat expatriates and ten international itinerants. The career paths of the 20 Swedish global careerists and how they narrate their careers are analyzed, and the two types of global careerists are compared.

Results show that the repeat expatriates and international itinerants differ in their subjective experiences of global careers, and how they narrate them. Three broad domains are identified that integrate a range of issues that are important for global careerists. These domains are the organization and career domain, the country and culture domain, and the family, communities, and networks domain. The repeat expatriates and international itinerants differ in how they relate to these and what is important to them.

The differences found have implications for organizations in terms of recruitment, management, and retention of a global talent pool.

This research contributes to the understanding of subjective experiences of global careers and integrates a range of aspects in the context of global careerists that are important to them. Moreover, it contributes to the understanding of global careers by differentiating between those with intra- and inter-organizational global careers.

When comparing novel centralized and distributed communications and video streaming services, the authors identified a need for a theoretic framework to position a multitude of ICT services and technologies according to their value proposition. Literature does not integrate existing value analysis concepts into a holistic theoretical framework. This paper aims to address this shortcoming by proposing a value analysis framework for ICT services capable of describing the value exchanges between different actors and their role constellations based on technological componentizations.

The paper evaluates a representative selection of communications and video streaming services and an extensive literature study on existing value analysis research was conducted to develop the framework and to verify it.

The paper demonstrates the applicability of the value analysis framework in communications and video streaming case studies, which are technically very different from each other but, at the abstraction level the framework provides, display very similar characteristics in value flows and role constellations.

The value analysis framework could be extended and verified with other case studies and complemented with quantitative modeling and system dynamics.

The authors combine existing literature into a proposal of a holistic value analysis framework and apply it to novel centralized and distributed communications and video streaming services. Both academics and practitioners can use the framework to evaluate the value proposition of ICT services and technologies.

The conception of markets as interfaces connecting semi-autonomous systems of producers and customers has led to an extensive use of social network analysis. So far, the network focus has been on connections among people, paying less attention to the crucial role played by connections between cultural elements (e.g., concepts, representations, ideas) in the way markets are formed and sustained. Such connections constitute “semantic networks” and are the focus of the present article. We attend to them by developing a network view of the cultural dimension of markets and apply it in an empirical setting where culture plays a crucial role – luxury watchmaking – to illustrate the impact of market semantic networks on a major outcome: price.

The purpose of this paper is to show the results of having a full authentication and authorization scenario in a web service‐oriented architecture. The Joint Research Activity 1 in the EU‐funded GEANT₂ project, in cooperation with Internet2, the US Department of Energy's ESnet and the Brazilian National Research and Educational Network, has defined a general framework for a multi‐domain network measurement infrastructure. The implementation, called Performance‐focused Service Oriented Network Monitoring Architecture, contains a set of services delivering performance measurements in a multi‐domain environment. The main goal of this work is to provide a multi‐federation identity solution to perfSONAR.

This is a case study of applying authentication and authorization standards to a web service‐oriented architecture. The prototype is implemented thanks to eduGAIN.

A multi‐federation identity solution for highly distributed web services environment has been gained.

The paper shows that it is possible to have a multi‐federated environment for web and non‐web applications applying current technologies. This is useful for practitioners of distributed software, specially in national research and educational networks.

This paper surveys the security architecture of the IP multimedia core network subsystem (IMS) of the third generation mobile system which is known in Europe as UMTS. The main features of the security architecture include user specific features protecting the access of the IMS user, such as authentication and key agreement when a user registers and integrity protection of IMS access signalling, but also features for the user, independent protection of SIP signalling in the IMS core network. Authenticated registration is given an in‐depth treatment.

A paradigm shift is observed in the last decade where transactional marketing is taken over by relationship marketing. Customer relationship management (CRM) has been an integral part of a business strategy in the current era. CRM integrates product sales, product marketing and, most importantly, customer service in a seamless manner to generate value for the organization as well as for its customers in short a win-win situation. Profoundly, CRM needs to be a part of the top management agenda and driven top-down instead of an IT initiative. Industrial revolution 4.0 is characterized by cyber-physical systems. Internet of Things (IoT) is the digital technology for the present and future. IoT primarily aids in gathering real-time data and transmitting the same over the internet to a central repository for consuming the same in business models. Real-time customer data analytics can be performed by customer-centric organizations to enhance CRM.

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.
