This chapter seeks to answer the question of how food tourists will be in the future based on technology and digitalisation. Therefore, two future food tourist scenarios are proposed: realistic and utopian. More specifically, considering the developing technology, from a realistic perspective, future food tourists are evaluated according to their experiences (virtual food experiences, personalised and hyper-personalised food experiences, interactive tech-based food experiences, and sensory food experiences), information sources and communication, tendencies (seeking transparency and traceability in the food supply chain and sustainability-oriented), and payments. However, a utopian future food tourist was also provided as the second future food tourist scenario. In this scenario, the dimensions of future food tourists include instantaneous food travel thanks to teleportation, brain–computer interface-based food experiences, lab-grown food experiences, and intergalactic food tourism. Since this is the first study providing future food tourist scenarios, it plays a guidance role for service providers and launches a scholarly debate in food tourism literature.

Purpose: The concept of a blue economy is gaining importance. 40% of the world’s population lives near coastal areas, and 80% of world trade is achieved using the seas. Sustainable financing for the blue economy is an emerging scope in climate finance. To date, little research has been published on this topic. Shiiba et al. (2022) proposed a conceptual framework for a blue finance mechanism; however, this approach was incomplete as it referred only to ocean sustainability and overlooked financial instruments and various financial models and schemes determined by a financial system, such as those in the United States, Germany, and Japan.

Methodology: The chapter aims to show the state of the art in sustainable financing in a blue economy and provide recommendations to improve the existing financial model.

A critical literature review, network approach, and case study.

Findings: The diversity and often uniqueness of blue economy projects underline the necessity for their financing system to be based on established regulatory frameworks in this area. However, specific solutions (e.g. the structure of acquired capital) should be considered on a case-by-case basis.

Limitations: Challenges include competition with government-owned sectors, infrastructure limitations, and limited public awareness of sustainable blue economy opportunities. Additionally, constraints like risk-averse local financial institutions and a lack of innovative business models hinder financing and entrepreneurship.

Warehouses are under pressure to operate as efficiently as possible. In pursuit of attaining high efficiency in the order picking process, the warehouse manager must take several planning decisions, typically supported by a central planning system. However, highly centralised work erodes the autonomy of warehouse workers, interfering with worker well-being and productivity. This study holistically explores the impact of a work system with more decision autonomy for order pickers.

We conduct a unique field experiment in a real-world warehouse and use a within-subjects design to compare two work systems, one with worker autonomy and one without. 18 permanent employees participate in our study, in which we measure both psychosocial and physical well-being as well as productivity. Post-experimental interviews are conducted to delve deeper into the observed effects.

Our study illustrates that involving order pickers in operational decisions can benefit their job satisfaction and motivation without compromising productivity. Although we fail to find significance at the conventional level (α = 0.05), we do find marginally significant effects of our treatment on physical well-being aspects. Furthermore, our intervention invoked a highly positive user experience.

We show that slightly loosening tight process control results in organisational and individual benefits without endangering smooth operational flows. The warehouse in this paper acknowledged this and decided to permanently work according to this philosophy.

This study is the first to holistically explore the effects of a participatory work setting in a real-world warehouse.

This study aims to propose a model to elevate the financial empowerment of Muslim women by rejuvenating the practice of Mahr in society and facilitating the affordability of men to pay that Mahr amount.

The approach of this study is to offer a model through the interest-free savings-based finance concept. The model comprises four stages; each stage of the model is mathematically formulated and graphically explained to ensure clarity and coherence. To further investigate the issue, the authors use a convenient sampling method to ask a small sample size of respondents (women) from different countries about their financial contribution and empowerment in the family.

This model enables women to turn their exclusive financial right into a source of earning without borrowing from any source or paying interest on the principal amount. Besides, it encourages accelerating men’s obligation to pay the Mahr to the women immediately during the marriage ceremony by facilitating men’s affordability. Almost 45% of respondents state that a woman’s financial contribution exalts her decision-making power and strengthens her financial position in the family.

The authors attempt to revitalize Mahr practice in Muslim society to accelerate the process of receiving a woman’s exclusive financial right and empower a family as a whole through the Mahr model.

Considering the model’s uniqueness, the developed and proposed Mahr model in this research is novel; to the best of the authors’ knowledge, no other study has been conducted and developed such a model using the Mahr concept.

This study aims to empirically investigate the effect of a firm’s blueness on stock returns by developing the blueness index. Ocean firms listed on NASDAQ Baltic, Copenhagen, Helsinki, Iceland and Stockholm were selected to test the hypothesis.

This study uses the system generalized method of moments technique and finds an inverse relationship between blueness and stock performance. As an alternative, their impact on stock performance is investigated using the environmental, social and governance (ESG) and environment (E) ratings. Additionally, by considering the blueness component, this study suggests a theoretical model to evaluate the utility function of the portfolio.

The results reveal that high-blue firms obtain lower returns than low-blue firms. This finding illustrates that high-blue firms obtain lower returns, as they comply with “blue” factors, and the possibility of risk would be lower. This study finds that lower ESG and E scores indicate ocean firms create lower emissions. Therefore, investors of high-blue firms obtain lower returns. To test the robustness of the blueness index, this study examines the effect of ESG and E ratings on a firm’s blueness. The results identify an inverse relationship between the ESG/E score and the blueness, illustrating that high-blue firms emit lower ocean emissions. The results of a theoretical model report that the proportion of investment in high-blue firms is higher for optimizing portfolio allocation.

This study determines firms’ blueness and impact on stock return. This study also considers ESG and E scores to identify their effect on ocean firm’s performance. The results contribute a theoretical understanding of factors determining the proportion of investment in high- and low-blue firms to optimize their portfolio.

Medellín, Colombia, experienced a remarkable social transformation in just two decades, leaving behind its troubled past of violence and insecurity. This study aims to identify the key actors and initiatives contributing to this transformation, considering cultural and social values shaping residents’ and visitors’ perceptions and determining the potential for the city’s brand. The research uses identity-based place branding theory and Delphi rounds to compare expert and promoter perspectives through surveys and tourist insights. The findings reveal recognising having a transformation in mind having offers guidelines for residents to propose tourism initiatives, aiding strategic city promotion and brand-building in collaboration with various organisations.

This paper aims to provide a full introduction, new classification, comparison and investigation of the challenges as well as applications of layerless 3D printing, which is one of the industry 4.0 pioneers.

Given the significance and novelty of uniform 3D printing, more than 250 publications were collected and reviewed in an unbiased and clear manner.

As a result, the majority of uniform parts printed in polymer form are known up to this point. In a novel division for better researchers’ comprehension, uniform printing systems were classified into three categories: oxygen inhibition (OI), liquid lubrication (LL) and photon penetration (PP), and each was thoroughly investigated. Furthermore, these three approaches were evaluated in terms of printing speed, precision and accuracy, manufacturing scale and cost.

The parameters of each approach were compared independently, and then a practical comparison was conducted among these three approaches. Finally, a variety of technologies, opportunities, challenges and advantages of each significant method, as well as a future outlook for layerless rapid prototyping, are presented.

Given the expansion of cities and urbanization, developing efficient and reliable transportation infrastructure, especially urban tunnels, is essential. Failure to maintain such complex construction facilities with intelligent equipment systems could result in human losses and impose huge costs on governments. Therefore, it is necessary to have practical maintenance plans and operational safety monitoring for urban tunnels, which leads to their long lifespan, increases users’ safety and reduces operation risks.

Hence, this research aims to evaluate the maintenance risks of urban tunnel lighting systems (UTLS) using a hybrid risk-based maintenance (RBM) approach. In this vein, three rounds of a fuzzy Delphi survey were conducted to consolidate the specific operation criteria and maintenance risk factors to the circumstances of Iran and UTLS. Furthermore, the fuzzy DEMATEL method was applied to determine the cause-and-effect relationships among the identified critical operation criteria. The identified risks associated with maintenance in UTLS were then analyzed and ranked using a combination of fuzzy ANP-VIKOR techniques.

The ranking of the various risks revealed that the “poor performance of switchboards in power supply due to faults in switchboard equipment” risk was ranked first, followed by the “poor performance of panels in the power supply due to unfavorable environmental conditions,” “The poor performance of panels in the power supply due to problems with switches (key failure)” and “The poor performance of panels in power supply due to burning fuses due to unauthorized current” risks. The findings of this study indicate that this hybrid maintenance method, developed as a risk-based network, provides reliability for maintaining urban tunnel lighting systems (UTLS).

It is anticipated that the findings of this research will considerably contribute to improving UTLS maintenance management while enhancing different stakeholders’ understanding of the most critical risks in maintenance, particularly toward the UTLS in Iran. An RBM management program can result in preparing and formulating policies, comprehensive guidelines or regulations for the maintenance of urban tunnels that are recommended for future research.

The aim was to investigate the effect of normal load on the tribological performance of laser cladded FeCoCrMoSi amorphous coating, which might choose the appropriate normal load for the friction reduction and wear resistance.

A FeCoCrMoSi amorphous coating was prepared on 45 steel using laser cladding, and the tribological performance of obtained coating under the different normal loads was investigated using a ball-on-disk tribometer.

The FeCoCrMoSi amorphous coating is composed of M₂₃C₆, Co₆Mo₆C₂ and amorphous phases, where the M₂₃C₆ hard phase enhances the coating hardness to increase the wear resistance and the Co₆Mo₆C₂ with the vein shape forms the strong mechanical interlock to play the role of friction reduction. The average coefficients of friction of containing amorphous FeCoCrMoSi coating under the normal loads of 3, 4 and 5 N are 0.68, 0.65 and 0.53, respectively, and the corresponding wear rates are 17.7, 23.9 and 21.9 µm3•N⁻¹•mm⁻¹, respectively, showing that the appropriate normal load is beneficial for improving its friction reduction and wear resistance. The wear mechanism is composed of adhesive wear, abrasive wear and oxidative wear, which is attributed to the high hardness of amorphous coating by the amorphous phase.

The FeCoCrMoSi amorphous coating was first applied for the improvement of 45 steel, and the effect of normal load on its tribological performance was investigated.

Megaproject's construction is essential for the development and economic growth of any country, especially in the developing world. In Kuwait, megaprojects are facing many restrictions that discourage their execution causing a significant delay in bidding, design, construction and operation phases with the execution quality being affected. The objective of this study is to develop a complexity measurement model using analytic hierarchy process (AHP) for megaprojects in Kuwait, with a focus on the New Kuwait University multi-billion campus Shadadiyah (College of Social Science, Sharia and Law (CSSL)) as a case study.

The study applies a hybrid fuzzy analytic hierarchy process (FAHP) method to compare the results with those obtained using the conventional AHP method. This can facilitate the project management activities during the different stages of construction. Data were collected based on the results of a two-round Delphi questionnaire completed by seniors and experts of the selected project.

It was found that project modeling methodology was responsible for complexity. It was grouped under several categories that include technological, goal, organizational, environmental and cultural complexities. The study compares complexity degrees assessed by AHP and FAHP methods. “Technological Complexity” scores highest in both methods, with FAHP reaching 7.46. “Goal Complexity” follows closely behind, with FAHP. “Cultural Complexity” ranks third, differing between methods, while “Organizational” and “Environmental Complexity” consistently score lower, with FAHP values slightly higher. These results show varying complexity levels across dimensions. Assessing and understanding such complexities were essential toward the completion of such megaprojects.

The contribution of this study is on providing the empirical evidential knowledge for the priority over construction complexities in a developing country (Kuwait) in the Middle East.
