Abstract

Purpose

This systematic literature review focuses on the following future advanced information and communication technologies (ICTs) applied in the maritime transport of cargo: Internet of Things (IoT), big data, cloud computing and autonomous ships/vessels (including unmanned ships/vessels). The review question is: “RQ: In what context and by means of what mechanism does the implementation of future advanced ICTs have disruptive impact on maritime transport?”.

Design/methodology/approach

The paper complies with the methodological requirements of systematic reviews. The information analysis and synthesis are based on the CIMO logic, referring to the context (C), intervention (I), mechanism (M) and outcome (O) of the implementation of future advanced ICTs in maritime transport.

Findings

The review identifies the contextual factors and components of the mechanism that lead to the disruptive impact of different types of future advanced ICT interventions on maritime transport.

Research limitations/implications

The review approaches only the most important future advanced ICTs that will disrupt maritime transport.

Practical implications

The maritime transport organizations should consider: intended outcome as intervention trigger; increased efficiency and responsiveness; benchmarking.

Originality/value

For the first time, the CIMO logic is applied in a systematic review focused on future advanced ICTs in maritime transport. The CIMO-DMT model is elaborated as a basis for further research. Ten directions of study are recommended in a future research agenda.

Abstract

The most suitable system architecture for higher education has been dramatically altered by rapid change in information technology and its use. The low cost of mini‐ and microcomputer technology has not only decentralized academic computing, it has made computing a ubiquitous tool for the student, faculty, and staff community across all disciplines. The microcomputer provides access to substantial computing at low cost, and stimulates distributed investment in computing capacity. However, the radical decentralization of computing in the university has also created substantial liabilities, such as increased difficulty in sharing information and resources. The characteristics of a powerful institution‐wide network, which will overcome existing problems with a decentralized environment, are detailed.

Abstract

Purpose

To utilize the idle computational resources in a network to collectively solve middle to large problems, this paper aims to propose an integrated distributed computing platform, Java distributed code generating and computing (JDGC).

Design/methodology/approach

The proposed JDGC is fully decentralized in that every participating host is identical in function. It allows standard, single machine‐oriented Java programs to be transparently executed in a distributed system. The code generator reduces the communication overhead between runtime objects based on a detailed analysis of the communication affinities between them.

Findings

The experimental results show that JDGC can efficiently reduce the execution time of applications by utilizing the networked computational resources.

Originality/value

JDGC releases the developers from any special programming considerations for distributed environment, and solves the portability problem of using system‐specific programming methods.

Abstract

Purpose

This paper aims to focus on the design of a decentralized observation and control method for a class of large-scale systems characterized by nonlinear interconnected functions that are assumed to be uncertain but quadratically bounded.

Design/methodology/approach

Sufficient conditions, under which the designed control scheme can achieve the asymptotic stabilization of the augmented system, are developed within the Lyapunov theory in the framework of linear matrix inequalities (LMIs).

Findings

The derived LMIs are formulated under the form of an optimization problem whose resolution allows the concurrent computation of the decentralized control and observation gains and the maximization of the nonlinearity coverage tolerated by the system without becoming unstable. The reliable performances of the designed control scheme, compared to a distinguished decentralized guaranteed cost control strategy issued from the literature, are demonstrated by numerical simulations on an extensive application of a three-generator infinite bus power system.

Originality/value

The developed optimization problem subject to LMI constraints is efficiently solved by a one-step procedure to analyze the asymptotic stability and to synthesize all the control and observation parameters. Therefore, such a procedure enables to cope with the conservatism and suboptimal solutions procreated by optimization problems based on iterative algorithms with multi-step procedures usually used in the problem of dynamic output feedback decentralized control of nonlinear interconnected systems.

Abstract

Purpose

This paper reviews the extant research on Web3.0 published between 2003 and 2022.

Design/methodology/approach

This study uses a topic modeling procedure latent Dirichlet allocation to uncover the research themes and the key phrases associated with each theme.

Findings

This study uncovers seven research themes that have been featured in the existing research. In particular, the study highlights the interaction among the research themes that contribute to the understanding of a number of solutions, applications and use cases, such as metaverse and non-fungible tokens.

Research limitations/implications

Despite the relatively small data size of the study, the results remain significant as they contribute to a more profound comprehension of the relevant field and offer guidance for future research directions. The previous analysis revealed that the current Web3.0 technology is still encountering several challenges. Building upon the pioneering research in the field of blockchain, decentralized networks, smart contracts and algorithms, the study proposes an exploratory agenda for future research from an ecosystem approach, targeting to enhance the current state of affairs.

Originality/value

Although topics around Web3.0 have been discussed intensively among the crypto community and technological enthusiasts, there is limited research that provides a comprehensive description of all the related issues and an in-depth analysis of their real-world implications from an ecosystem perspective.

Abstract

Seeks to isolate those intra‐organizational factors affecting the information technology (IT) structure of the firm. Analyses this phenomenon from two management perspectives: the agency and governance perspective on the one hand, and the management characteristics perspective on the other. Using a sample of 72 large organizations, empirical results indicate that information technology structure (centralized versus decentralized) is strongly related to management equity ownership, to concentration of stock holding and to the age of the CEO. For example, an organization where top executives and managers own a relatively high percentage of the company′s stock, possesses a more centralized information technology structure than an organization with a relatively lower percentage of management ownership. This means that user departments in the latter have more control over their IT functions than users in the former. On the other hand, companies with a high level of stock concentration have a more decentralized IT structure. The research also revealed a statistically significant relationship between a company′s equity‐to‐debt ratio and the age of the CEO on the one hand, and the level of IT centralization on the other.

Abstract

What is the underlying trend in IT structures? Why have individual businesses taken different stands with regard to their IT structures? There has been an ongoing debate concerning these questions with limited resolution. The issues surrounding IT structures are analysed in order to prepare managers to cope with the above two questions throughout the 1990s. Owing to the continuing progress in hardware and software technology, decentralised IT structures will continue to become more accessible and attractive in the 1990s. As a result, the users of IT services will assume an increasing share of responsibilities for producing their locally needed IT services. Generally speaking, the responsibilities of central IT departments will continue to decrease during the 1990s. Meanwhile owing to differences among businesses with respect to their organisational context variables, individual businesses will continue to subscribe to different IT structures ranging from relatively centralised to relatively decentralised.

Abstract

Purpose

Emerging pervasive computing scenarios require open service frameworks promoting situated and self‐adaptive behaviors, and supporting diversity in services and long‐term evolvability. This suggests adopting a nature‐inspired approach, where pervasive services are modeled and deployed as autonomous individuals in an ecosystem of other services, data sources, and pervasive devices. However, there are many possibly nature‐inspired metaphors that can be adopted, and choosing one may require a careful analysis of the pros and cons of the different metaphors. The purpose of this paper is to analyze the key requirements and desiderata for next generation pervasive computing services and associated infrastructures.

Design/methodology/approach

In this paper, the authors introduce and critically analyze a number of natural metaphors that can be adopted to realize these concepts and survey relevant proposals in the area.

Findings

The key result of this survey is that a uniform reference architecture can be a useful guide when framing the challenges involved in the design and implementation of future self‐adaptive pervasive service ecosystems.

Originality/value

The survey in this paper, along with the proposed reference architecture, can be effective starting points towards the definition and implementation of general‐purpose nature‐inspired pervasive service ecosystems.

Abstract

Examines ‐ in a study involving 92 large publicly‐held organizations ‐ the relationships between information technology (IT) structure, control and industry turbulence. Notes that despite the fact that some have called centralized systems electronic dinosaurs, many companies are turning to this traditional approach because it does offer one thing that decentralized systems generally lack, namely, control. Cites results indicating that information technology structure (centralized versus decentralized) is strongly related to management equity ownership, concentration of stock holdings, and the level of turbulence which firms face. Notes, for example, that an organization where top executives and managers own a relatively high percentage of the company’s stock possesses a more centralized IT structure than an organization with a relatively lower percentage of management ownership. Points out that this means that user departments in the latter have more control over their IT functions than do users in the former, but that, on the other hand, companies with high levels of stock concentration have more decentralized IT structures. In addition, concludes that the research revealed a statistically positive significant relationship between the level of turbulence firms face and the degree of IT centralization.
