This paper aims to obtain optimal specialization mode and level for complex network or system structures. In the e-commerce system, this paper studies the changes of each transaction subject in the process of ecological structure based on the income level of each transaction subject.

This paper aims to research the change of transaction efficiency evolution process of intermediaries. With the improvement of transaction efficiency, intermediaries interact with other transaction subjects at given modes in e-commerce systems. This paper analyzes the relationship between the factors of production and trade and explains the quantitative relationship between them in the form of mathematical modeling. An evolution simulation framework is established to elaborate the simulation process and method of crowd network in e-commerce ecosystem and then sets up the simulation experiment.

During simulation processes, the changes of data are observed and analyzed to obtain the optimal evolution paths and specialization modes. Furthermore, this paper provides solid supports for the research of the quantitative analysis of ecological structure evolutions.

Evolution simulation of ecological structure is first proposed in the topic of crowd network. It is with the aid of the concept of ecology, the theory and method, simulation of complex network structure and system structure. This paper analyses and researches the evolution process of optimal specialization modes and intelligent level of crowd networks with transaction efficiency changing. The ecological structure optimal evolution paths can be obtained by trend of simulations.

This paper aims to explore issues arising from ṣukūk (Islamic bonds) on blockchain, including Sharīʾah (Islamic law) and legal matters.

A qualitative methodology is used in conducting this research where relevant literature on ṣukūk was reviewed. Through a doctrinal approach, the paper presents analyses on the practice of ṣukūk and ṣukūk on blockchain by discussing its legal, Sharīʾah and regulatory issues. This culminates in a conceptual analysis of blockchain ṣukūk and its peculiar challenges.

This paper reveals that digitizing ṣukūk issuance through blockchain remedies certain inefficiencies associated with ṣukūk transactions. Indeed, structuring ṣukūk on a blockchain platform can increase transparency of underlying ṣukūk assets and cash flows in addition to reducing costs and the number of intermediaries in ṣukūk transactions. The paper likewise brings to light legal, regulatory, Sharīʾah and cyber risks associated with ṣukūk on blockchain that confront investors, practitioners and regulators. This calls for deeper collaboration in research among Sharīʾah scholars, lawyers, regulators and information technology experts.

As a pioneering subject, the paper notes the prospects of blockchain ṣukūk and the current dearth of literature on it. The paper would assist relevant Islamic capital market entities and authorities to determine the potential and impact of blockchain ṣukūk in their respective businesses and the financial system.

Blockchain ṣukūk will assist in addressing issues inherent in classical ṣukūk and in paving the way to innovative solutions that will facilitate and enhance the quality of ṣukūk transactions. For that, ṣukūk would require appropriate regulatory technology to address its governance and regulation peculiarities.

Integrating ṣukūk with blockchain technology will add value to it. The paper advances the idea that blockchain ṣukūk revolutionises ṣukūk and enhances its practice against known inadequacies.

While the literature on multitier supply chain management traditionally assumes that first-tier suppliers belong to the visible proportion of the supply base, intermediaries might limit focal firms' visible horizon already at this stage. High power asymmetries promoting centrality and complexity in the supply network are seen as a particular root cause that limits the impact of governance mechanisms for sustainability. To map the space for governance mechanisms in a network-sensitive context more comprehensively, the study analyzes supply network characteristics from a power perspective.

This research is conceptual. To better understand power imbalances and mutual dependencies from network centrality and complexity, network configurations were constructed drawing on resource dependence theory. These configurations allow deducing the impact of (non-)mediated governance mechanisms for a sustainable development in the supply network. An agenda to stimulate future empirical and model-based research is accordingly presented.

The research shows that those networks with densely interconnected first-tier suppliers promote network centrality and complexity, leading to an inverted U-shape relationship between the focal firm's exertion of coercive power and the sustainability performance in the supply network. The findings allow a more comprehensive theoretical grounding for mapping governance approaches in a network-sensitive context and provide insights on how to avoid negative effects from power asymmetries.

The findings suggest the need for accompanying, indirect governance mechanisms already at the stage of first-tier suppliers based on non-mediated forms of power, such as referent power, also promoting disintermediation. Purchasing companies may also consider using digital platform technologies that foster disintermediation, such as blockchain technology.

By studying intermediaries from a power and network perspective, the conceptualization adds to the discussion on governance in multitier sustainable supply chain networks in various industries. Furthermore, it contributes to the increasing efforts of middle-range theorizing in logistics and supply chain management. The results partially challenge previous assumptions on the moderating role of specific network characteristics.

Amidst burgeoning attention for global value chains (GVCs) in international business (IB), this paper aims to identify a clear “missing link” in this literature and discusses implications for research and corporate social responsibility (CSR) policy-making and implementation.

The paper combines an overview of relevant literature from different (sub)disciplinary fields, with insights from practitioner and expert interviews and secondary data.

Because IB GVC research stems from a focus on lead firms and their producing suppliers, it lacks attention for intermediary actors that may significantly impact the organization of production in general, and firms’ CSR commitments in particular. Import intermediaries are often “hidden” in GVCs. This paper indicates the emergence of GVC parallelism with “frontstage” chains managed by lead firms and increasingly exposed to public scrutiny following calls for transparency and CSR, and “backstage” ones in which buyers and intermediaries operate more opaquely.

This study points at salient yet little known practices and actors that influence the organization of production and the implementation of CSR policies in various ways, and therefore offers ground for reflection on the design of proper supply chain and CSR policies.

This study exposes a hitherto neglected category of actors in GVCs and broader IB research and discusses implications, relevance and areas for further investigation. An illustrative example explicates the importance of carefully considering this “missing link”. The study emphasizes the need for further study into ways in which both lead firms and intermediaries deal with contradicting demands of implementing CSR policies and offering competitive prices with short lead times.

The study aims to provide an exploratory investigation of the magnitude of the customer-centric approach in the specific area of healthcare as a contribution to the scarce and preliminary literature on this topic. In particular, it explores the role of sharing economy-based (SE-based) platforms as an experiential touchpoint to co-create value within different levels. Specifically, the purpose of the study is threefold. First, it aims to address the service experience innovation in healthcare with a customer-centric approach. Second, it seeks to define the role of the SE-based platform as a touchpoint to redefine business processes, and third, it measures the co-created value within the network when redesigning the service experience.

To address the research question, the authors proposed an analysis of service innovation and customer centricity in healthcare networks by using the case study of Saluber, an SE-based platform that offers logistics services for non-emergency medical transportation in the Campania region (south of Italy). By using a qualitative approach, the authors analysed primary and secondary data from multiple sources of evidence.

The results show that a customer-centric approach based on the SE-based platform can improve the customer experience and help to redesign and expand the business processes of healthcare organisations. A multilevel model demonstrates the possible service innovations that use SE principles that can co-create value for the customer (micro level), for the healthcare network (meso level) and for the community (macro-level).

This study provides managerial implications for the players who intend to take advantage of the possibilities offered by service innovations developed by the health and social organisations in the network. The SE-based platform helps redefine business processes to improve clinical and financial outcomes and improves the overall customer experience within this network.

This study allows new and important reflections from ethical, social and managerial points of view and underlines how digital platforms act as a support for healthcare services, not as a substitute.

Decentralized finance (DeFi), enabled by blockchain, could bring about a new financial system, where peers will interact directly, with little or no place for traditional intermediation. However, some crucial tasks cannot be left solely to an algorithm and, consequently, most DeFi applications still require human decisions. The aim of this research is to assess the role of intermediation in the light of DeFi, analysing how humans and algorithms will interact.

The authors based their work on a twofold qualitative methodology, first analysing publicly available secondary data, particularly from white papers and DeFi Pulse (a website providing data on DeFi solutions) and then running two focus group discussions.

DeFi does not eliminate financial intermediation, but enables it to be performed in new ways, where decentralization means that no single entity can hold too much power or monopoly. DeFi has, however, inherited risks from the underlying technologies that unintentionally facilitate illegal behaviour and can hamper the authorities’ supervision. The complex duality algorithm- vs human-based actions will not be solved indisputably in favour of the former, as DeFi solutions can range from requiring algorithms to play a dominant role, to enabling greater human interaction by actively involving more people.

This research contributes to the emerging debate between algorithm- and human-based intermediation, especially in relation to the standing literature on financial intermediation, where considerations made in the light of the newest theories on blockchain and DeFi are still scarce.

The issue of cybersecurity has been cast as the focal point of a fight between two conflicting governance models: the nation-state model of national security and the global governance model of multi-stakeholder collaboration, as seen in forums like IGF, IETF, ICANN, etc. There is a strange disconnect, however, between this supposed fight and the actual control over cybersecurity “on the ground”. This paper aims to reconnect discourse and control via a property rights approach, where control is located first and foremost in ownership.

This paper first conceptualizes current governance mechanisms through ownership and property rights. These concepts locate control over internet resources. They also help us understand ongoing shifts in control. Such shifts in governance are actually happening, security governance is being patched left and right, but these arrangements bear little resemblance to either the national security model of states or the global model of multi-stakeholder collaboration. With the conceptualization in hand, the paper then presents case studies of governance that have emerged around specific security externalities.

While not all mechanisms are equally effective, in each of the studied areas, the author found evidence of private actors partially internalizing the externalities, mostly on a voluntary basis and through network governance mechanisms. No one thinks that this is enough, but it is a starting point. Future research is needed to identify how these mechanisms can be extended or supplemented to further improve the governance of cybersecurity.

This paper bridges together the disconnected research communities on governance and (technical) cybersecurity.

This paper analyses the research in Library and Information Science (LIS) and reports on (1) the status of LIS research in 2015 and (2) on the evolution of LIS research longitudinally from 1965 to 2015.

The study employs a quantitative intellectual content analysis of articles published in 30+ scholarly LIS journals, following the design by Tuomaala et al. (2014). In the content analysis, we classify articles along eight dimensions covering topical content and methodology.

The topical findings indicate that the earlier strong LIS emphasis on L&I services has declined notably, while scientific and professional communication has become the most popular topic. Information storage and retrieval has given up its earlier strong position towards the end of the years analyzed. Individuals are increasingly the units of observation. End-user's and developer's viewpoints have strengthened at the cost of intermediaries' viewpoint. LIS research is methodologically increasingly scattered since survey, scientometric methods, experiment, case studies and qualitative studies have all gained in popularity. Consequently, LIS may have become more versatile in the analysis of its research objects during the years analyzed.

Among quantitative intellectual content analyses of LIS research, the study is unique in its scope: length of analysis period (50 years), width (8 dimensions covering topical content and methodology) and depth (the annual batch of 30+ scholarly journals).

The purpose of this paper is to discuss findings from an Arts and Humanities Research Council (AHRC)-funded research project into the heritage culture of British folk tales. The project investigated how such archival source material might be made relevant to contemporary audience via processes of artistic remediation. The research considered artists as “cultural intermediaries”, i.e. as actors occupying the conceptual space between production and consumption in an artistic process.

Interview data is drawn from a range of 1‐2‐1 and group interviews with the artists. These interviews took place throughout the duration of the project.

When artists are engaged in a process of remediation which has a distinct arts marketing/audience development focus, they begin to intermediate between themselves and the audience/consumer. Artist perceptions of their role as “professionals of qualification” is determined by the subjective disposition required by the market context in operation at the time (in the case of this project, as commissioned artists working to a brief). Artists’ ability (and indeed willingness) to engage in this process is to a great extent proscribed by their “sense-of-self-as-artist” and an engagement with Romantic ideas of artistic autonomy.

A consideration of the relationship between cultural intermediation and both cultural policy and arts marketing. The artist-as-intermediary role, undertaking creative processes to mediate how goods are perceived by others, enables value-adding processes to be undertaken at the point of remediation, rather than at the stage of intermediation.
