Abstract
Purpose
This paper critically reviews and analyzes the trends in waqf studies within the Islamic economics literature. It analyzes the recent developments and debates in waqf reform and advances the argument for prioritizing research on waqf economics; the waqf dimension that is concerned with modelling how to utilize it to enhance productivity, consumption, redistribution, investment and saving, and generally contribute sustainably towards poverty reduction, economic empowerment and development.
Design/methodology/approach
The paper is conceptual in nature, focusing on a systematic historical analytical review of waqf studies in Islamic economics literature.
Findings
Despite the documented historic role of waqf in constructing the Muslim socio-economic architecture as the third economic sector and a mechanism for civilizational development and renewal, it received little attention in the early writings on modern Islamic economics. While the past one decade has witnessed a renewed interest in waqf research, most studies focus on its legal, juristic and administrative aspects in addition to the nostalgic reflections on its past glories. Little attention is comparatively given to the socio-economic aspect, which represents the actual raison d’être for its institutionalization.
Practical implications
An important task ahead of the current generation of Islamic economists is to formulate waqf-based development models that are rooted in proper diagnosis and deep understanding of the current socio-economic realities of the OIC member countries for the purpose of uplifting living standards and stimulating sustainable socio-economic development.
Originality/value
The paper contributes to the debate on priorities in waqf studies and practice and can trigger further discourses and research on the future of research in waqf economics.

Abstract
Purpose
The authors have faced rapid technological developments over the past few years. Still, the authors face challenges of maritime supply chain inefficiency, high costs and the low competitiveness of Indonesian ports. In line with the flow of this research, the purpose of this paper is to conceptualise best practices to improve port connectivity, which impacts improving maritime logistics capabilities in Indonesia that are relevant to the current situation.
Design/methodology/approach
The authors utilise surveys and interviews as a data collection method, where several sources were actors in the maritime logistics industry. The authors also use secondary data from the Ministry of Transport of the Republic of Indonesia, online databases as well as trade magazines and newspapers. This paper conducts a multiple case study and principal component analysis (PCA) to meet the research objectives.
Findings
The intention to use port digitisation services will increase if the perceived usefulness of the service also increases. Also, if the negative coefficient of user trust rises, it will bring a very sharp decrease in customers' intentions to use. Furthermore, the high estimated value of context indicates that users expect to have a good experience using the application and bring benefit to their business.
Originality/value
Based on the authors’ knowledge, there has been no review about port digitalisation, specifically in Indonesia. The authors initially provided best practices to improve port connectivity, which can impact improving maritime logistics capabilities.

Abstract
Purpose
This study provides a systematic literature review and categorization of the costs reported in the literature for the introduction of new vaccines, focusing on sub-Saharan Africa within LMICs, where vaccines are highly needed, financial resources are scarce and data are lacking and scattered.
Design/methodology/approach
A systematic literature search of PubMed and Web of Science databases was conducted according to the PRISMA requirements. Searches also included the relevant grey literature. In total, 39 studies were selected and nine cost categories were investigated to build a comprehensive framework.
Findings
The paper considers nine cost categories that cover the whole life of the vaccine, from its initial study to its full implementation, including for each of them the relevant subcategories. The systematic review, besides providing specific quantitative data and allowing to assess their variability within each category, points out that delivery, program preparation, administration and procurement costs are the most frequently estimated categories, while the cost of the good sold, costs borne by households and costs associated to AEFI are usually overlooked. Data reported on R&D costs and investment in the production plant differ significantly among the selected contributions.
Originality/value
The literature contributions on cost estimation tend to focus on a precise vaccine, a specific geographic area, or to adopt a narrow approach that captures only a subset of the costs. This article presents a rich and inclusive set of the economic quantitative data on immunization costs in limited-resource countries.

Abstract
Purpose
This paper aims to study the reliability of the high-speed train operation control system in the Chinese Train Control System Level 3 (CTCS-3) operating mode.
Design/methodology/approach
Dynamic fault tree and Bayesian network method are adopted to analyze the reliability and weakness of the CTCS-3 system.
Findings
First, a physical architecture and data flow diagram of the CTCS-3 system are established according to the typical structure and functions of the CTCS-3 system. Second, the dynamic fault tree of the CTCS-3 system is constructed. Considering the prior probability of the bottom event and the existence of dynamic redundancy, the dynamic fault tree is transformed into a Bayesian net. The reliability of the CTCS-3 system is carried out based on the prior probability and the weakness that affects the reliability of the system based on the posterior probability is also analyzed by the Bayesian network. Finally, it is disclosed that the impact of the on-board subsystem on the reliability of the CTCS-3 system is generally greater than that of the ground subsystem. The two weakest modules in the onboard subsystem are the driver-machine interface (DMI) and balise transmission module (BTM) and the weakest one in the ground subsystem is Balise. The analysis results are generally consistent with the malfunctions in the field operation of China’s high-speed railway.
Originality/value
(1) By reasoning, the reliability of the train operation control system in the CTCS-3 operating mode meets the standard requirements.
(2) Through backward reasoning, it is found that the failure of the onboard subsystem leads to a greater probability of failure of the train control system.
(3) The DMI, BTM and automatic train protection computer unit modules are weak components in the onboard subsystem. Vital digit input&output, train interface unit and train security gateway are rarely involved in previous research, the result in this paper shows that these three modules are also weak components in the subsystem, which requires attention.
