Abstract
Purpose
The increasing frequency and intensity of the extreme weather events could cause devastating consequences in tourism. Climate change–related extreme weather events and their relation to tourism is an emerging field for education and research. The purpose of this study is to categorize the impact of climate change on tourist destinations with regard to extreme weather-related risks in outdoor recreation and tourism. Managerial implications for policymakers and stakeholders are discussed.
Design/methodology/approach
To outline the risks from climate change associated with tourism, this study uses the Prisma analysis for identification, screening, checking for eligibility and finding relevant literature for further categorization.
Findings
Based on a thoroughly examination of relevant literature, risks and threats posed by climate change could be categorized into following four areas: reduced experiential value in outdoor winter recreation; reduced value in beach scenery and comfort; land degradation and reduced biodiversity; and reduced value in personal safety and comfort in tourism. It also focuses on the significance of using big data applications in catastrophic disaster management and risk reduction. Recommendations with technology and data analytics to continuously improve the disaster management process in tourism education are provided based on findings of this study.
Originality/value
Primary contributions of this study include the following: providing a summarized overview of the risks associated with climate change in terms of tourist experiential value for educational implications; and revealing the role of data analytics in disaster management in the context of tourism and climate change for tourism education.

Abstract
Purpose
The purpose of this study is to calculate the normal force of a two degree of freedom direct drive induction motor considering coupling effects based on an analytical model. Compared with the traditional single degree of freedom motor, normal force characteristics of two-degree-of-freedom direct drive induction motor (2DOFDDIM) is affected by coupling effect when the machine is in a helical motion. To theoretically explain the influence mechanism of coupling effect, this paper conducts a quantitative analysis of the influence of coupling effect on normal force based on the established analytical model of normal force considering coupling effect.
Design/methodology/approach
Firstly, the normal forces generated by 2DOFDDIM in linear motion, rotary motion and helical motion are investigated and compared to prove the effect of the coupling effect on the normal force. During this study, several coupling factors are established to modify the calculation equations of the normal force. Then, based on the multilayer theoretical method and Maxwell stress method, a novel normal force calculation model of 2DOFDDIM is established taking the coupling effect into account, which can easily calculate the normal force of 2DOFDDIM under different motions conditions. Finally, the calculation results are verified by the results of 3D finite element model, which proves the correctness of the established calculating model.
Findings
The coupling effect produced by the helical motion of 2DOFDDIM affects the normal force.
Originality/value
In this paper, the analytical model of the normal force of 2DOFDDIM considering the coupling effect is established, which provides a fast calculation for the design of the motor.

This study aims to investigate the relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women.
Abstract
Purpose
This study aims to investigate the relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women.
Design/methodology/approach
This cross-sectional study was conducted with 562 45–64-year-old postmenopausal women who presented to a Family Health Center. To collect the data, the Descriptive Information Form and Food Frequency Questionnaire were used. In the data analysis, numbers, percentages, mean, standard deviation and multiple linear regression analysis were used.
Findings
The multiple linear regression analysis demonstrated that dietary putrescine intake was negatively associated with systolic blood pressure (ß = −0.179, p < 0.001), dietary spermidine intake was positively associated with waist circumference (WC) (ß = 0.142, p = 0.013), systolic blood pressure (ß = 0.188, p = 0.001), diastolic blood pressure (ß = 0.218, p < 0.001), body mass index (BMI) (ß = 0.169, p = 0.003) and waist-to-height ratio (WHtR) (ß = 0.156, p = 0.006), and dietary spermine intake was negatively associated with WC (ß = −0.158, p = 0.003), systolic blood pressure (ß = −0.195, p < 0.001), BMI (ß = −0.107, p = 0.042) and WHtR (ß = −0.138, p = 0.009).
Research limitations/implications
Owing to the study’s cross-sectional nature, the lack of succession in the cause–effect relationship, the use of self-report Food Frequency Questionnaire to determine dietary polyamine intake and the inability to analyze seasonal differences are among the limitations of the study.
Originality/value
In this study, an association was determined between dietary polyamines, metabolic risk parameters and anthropometric measurements. The findings suggest that dietary polyamines in human health should be further investigated owing to the increasing metabolic risk parameters.

Abstract
Purpose
Developing a sense of belonging among immigrant youth in multicultural contexts has attracted significant attention from scholars during the last few decades. Studies have already underscored how various educational factors hinder or facilitate students’ sense of belonging to the school or the larger society. Although most students in Hong Kong schools are ethnic Chinese, a significant number of non-Chinese children make students diversity an essential aspect of schooling. The study investigated how schools can develop a sense of belonging among ethnic minority youth in Hong Kong.
Design/methodology/approach
As the education system in Hong Kong lacks a multicultural education policy, how can schools help develop a sense of belonging to the school and the larger society among young ethnic minority people? To answer this question, this paper consolidates the two sets of data originally gathered for two research projects. The data was collected through semi-structured in-depth interviews with nine secondary school teachers (Chinese and non-Chinese) and 15 students (non-Chinese) and analysed thematically.
Findings
The thematic analysis of the qualitative data identified several challenges and opportunities for developing ethnic minority students’ sense of belonging in Hong Kong.
Research limitations/implications
Researchers in comparative education can further explore how multicultural education and inclusive education approach together can help ensure inclusive and equitable quality education for all and cater to students' diverse learning needs across the education systems.
Practical implications
Given that the aims of multicultural education and inclusive education resonate with each other, schools can focus on the Whole School Approach to developing a sense of belonging among ethnic minority youth in Hong Kong. However, policymakers and practitioners may need to adopt a multifaceted perspective on inclusive education that strives to ensure equitable quality education for all.
Originality/value
The study contributes to the existing body of scholarship on multicultural education and inclusive education. The study findings underscore the importance of an interdisciplinary research framework in education and advocate an integrative approach to supporting students with diverse learning needs in multicultural contexts.

Abstract
Purpose
The main purpose of this study was to propose theoretical calculation models to evaluate the theoretical bending strengths of welded wide-flange section steel beams with local buckling at elevated temperatures.
Design/methodology/approach
Steady-state tests using various test parameters, including width-thickness ratios (Class 2–4) and specimen temperatures (ambient temperature, 400, 500, 600, 700, and 800°C), were performed on 18 steel beam specimens using roller supports to examine the maximum bending moment and bending strength after local buckling. A detailed calculation model (DCM) based on the equilibrium of the axial force in the cross-section and a simple calculation model (SCM) for a practical fire-resistant design were proposed. The validity of the calculation models was verified using the bending test results.
Findings
The strain concentration at the local buckling cross-section was mitigated in the elevated-temperature region, resulting in a small bending moment degradation after local buckling. The theoretical bending strengths after local buckling, evaluated from the calculation models, were in good agreement with the test results at elevated temperatures.
Originality/value
The effect of local buckling on the bending behaviour after the maximum bending strength in high-temperature regions was quantified. Two types of calculation models were proposed to evaluate the theoretical bending strength after local buckling.

Abstract
Purpose
The COVID-19 pandemic is known to have affected the logistics and supply chains; however, there is no adequate empirical evidence to prove in which way it has affected the relationship between the stocks related to this field with the corresponding cryptocurrencies. This paper aims to test the dynamic relationship of cryptocurrencies with supply chain and logistics stocks.
Design/methodology/approach
In this paper, the author tests the causal and long-run relationship between logistics and supply chain stocks with the corresponding cryptocurrencies related to these fields, or those that are known to exhibit characteristics that can be utilized by these fields, testing also whether the COVID-19 pandemic affected this relationship. To do so, the author performs the variable-lag causality to test the causal relationship, and examines if this relationship changed due to COVID-19. The author then implements the multifractal detrended cross-correlation analysis to investigate the characteristics of a possible long-run relationship, testing also whether they changed due to COVID-19.
Findings
The results indicate that there is a positive long-run relationship between each logistics and supply chain stocks and the corresponding cryptocurrencies, before and also during COVID-19, but during COVID-19 this relationship becomes weaker, in most cases. Moreover, before COVID-19, the majority of the cases indicate a causal direction from cryptocurrencies to the stocks, while during COVID-19, the causal relationships decrease in multitude, and most cases unveil a causal direction from the stocks to cryptocurrencies.
Originality/value
The causal pattern changed during COVID-19, and the long-run relationship became weaker, showing a change in the dynamics in the relationship between logistics and supply chain stocks with cryptocurrencies.

Abstract
Purpose
In this study, the authors clarified the differences in consumers' benefit–risk perceptions based on changes (description order and amount) in the benefit–risk information after an assessment of the health impact of foods.
Design/methodology/approach
The authors set the following four benefit–risk information groups relating to fatty fish consumption—Group 1: benefit/simple–risk/detail; Group 2: risk/detail–benefit/simple; Group 3: benefit/detail–risk/detail; Group 4: risk/detail–benefit/detail. The authors conducted a randomized controlled study on June, 2022, involving 7,200 Japanese consumers aged over 18 years.
Findings
There were no significant differences in the risk and benefit perceptions. Furthermore, the logistic regression analysis identified women and benefit perception as significant influencing factors of “no-risk acceptance.”
Originality/value
This study found that all four message formats were acceptable to consumers due to high-benefit/low-risk perceptions. However, despite the difference in message types used in benefit–risk communication, there was no effect on risk acceptance among consumers. Public agencies should design their communication with considerations toward women and benefit perceptions.

Abstract
Purpose
Product quality standardization is the solution to market collapses due to quality-insensitive pricing regimes prevalent in West African (WA) rice value chains. However, access to local rice that is differentiated by quality standards is limited. This paper explores feasibility of quality standardization of local rice and evaluates how its price–quality connecting effect depends on retailer characters/reactions.
Design/methodology/approach
This study uses panel data from a wholesale randomized control trial (RCT) and three surveys of 135 rice retailers in Ghana.
Findings
Improved local food value chains and access to quality differentiated products are impactful entry points for import substitution policies. The strength of interretailer competition, retail infrastructure and wholesaler activities matter for a stronger connection of prices and quality, given uptake of quality-standardized local rice.
Research limitations/implications
Access to quality-differentiated local rice can be increased via private and third-party certification. This addresses the prevailing inefficient pricing and its related problems. The positive impacts of such access would be magnified by designing quality certification interventions to elicit regular-frequent purchases by retailers and target retailers with adequate retail infrastructure in high competition areas. However, this study only explored profitability and opportunities for strategic behavior as the behavioral basis for quality-sensitive pricing. Other impact mechanisms could be explored in further research that includes consumer data.
Originality/value
Despite their difficulty and limited use in value chains studies, RCT and panel data methods are used. This study is the first to empirically analyze feasibility of introducing product standardization, a missing institution in the WA local rice markets.

Abstract
Purpose
It is necessary to implement green supply chains. But green development needs to be gradual and coexist with ordinary products in the market. This paper aims to study the green and ordinary product pricing and green decision-making under chain-to-chain competition.
Design/methodology/approach
This paper considers consumers' multiple preferences and takes two competitive supply chains with asymmetric channels as the research object. Through the construction of the game models involving different competitive situations, this paper studies the pricing, green decision-making and the supply chains' profits, and discusses the impact of consumer green preference, channel preference, green investment and competition on the decision-making and performance. Finally, this paper further studies the impact of the decision structure on the environmental and economic benefits of supply chains.
Findings
The results show that consumer green preference has an incentive effect on the green supply chain and also provides an opportunity for the regular supply chain to increase revenue. Specifically, consumers' preference for green online channels improves the product greenness, but its impact on the green retailer and regular supply chain depends on the green investment cost. Moreover, competition not only fosters product sustainability, but also improves supply chain performance. This paper also points out that the decentralization of the regular supply chain is conducive to the environmental attributes of the green product, while the environment-friendly structure of the green supply chain is different under different conditions. In addition, the profit of a supply chain under centralized decision is not always higher than that under decentralized decision.
Originality/value
The novelty of this paper is that it investigates the pricing of two heterogeneous alternative products and green decision-making for the green product under the competition between two supply chains with asymmetric channels, in which the green supply chain adopts dual channels and the regular supply chain adopts a single retail channel.

Abstract
Purpose
Despite the large number of Indonesian health-care workers working as migrant care workers in Japan, there is a lack of studies that have investigated this phenomenon or assessed the working conditions of Indonesian care workers working in Japanese aged-care facilities. This study aims to explore the work experiences of Indonesian care workers in Japan.
Design/methodology/approach
A qualitative descriptive research design was used, and a purposive sample of 18 Indonesian health-care workers (12 nurses and six midwives) who work as care workers in Japan participated in this study. Semistructured interviews were conducted with these participants between December 2022 and January 2023. The data were analyzed using content analysis. The Consolidated Criteria for Reporting Qualitative Research checklist was used to report this study.
Findings
Four key themes emerged from the data: easy but mentally challenging, being a care worker is a blessing, working in a partially Muslim-friendly environment and enjoy living: prefer to stay longer.
Originality/value
The work experiences of Indonesian care workers in Japan are complex and multifaceted. By understanding their experiences and needs, the authors can work toward creating more inclusive and supportive workplaces for all.
