Abstract
Purpose
The purpose of this paper is to understand middle class household food providers’ attitudes to the regulation of food marketing and the promotion of healthy food practices.
Design/methodology/approach
A cross-sectional, online questionnaire survey was administered to 3,925 urban respondents in Indonesia, Melbourne, Shanghai, Singapore and Vietnam. Cross-tabulation, confirmatory factor analyses and multiple regression analyses were employed.
Findings
Most respondents supported government communications to promote healthy eating and to a lesser extent, regulatory measures to control unhealthy food marketing. Personal values and country of residence were more strongly associated with the respondents’ views than demographic variables. Overall, strongest support for nutrition promotion and for stricter regulation of food marketing was seen in Shanghai, Indonesia and Vietnam. Broadly, two groups were identified across the region: those who held equality-nature or tradition-security-conformity personal values, who disapproved of food marketing but supported government health promotion campaigns, and, those with stronger hedonist values who held opposite views.
Research limitations/implications
First, a wider range of personal values could be included in future studies to better represent Asian values. Second, changes in population views could be assessed in future longitudinal studies. Finally, future studies should include dietary assessments and the views of people from a variety of socio-economic and cultural backgrounds.
Practical implications
These findings suggest that health policy makers and communicators need to frame their communications to match the world views of household food providers in their countries.
Originality/value
The study provides confirmation of attitude-values theories within five different countries in the Asia Pacific region and demonstrates the importance of personal values and country of residence in influencing food providers’ views.

This paper aims to examine how social marketing intervention programmes to measure, evaluate and document social marketing impact.
Abstract
Purpose
This paper aims to examine how social marketing intervention programmes to measure, evaluate and document social marketing impact.
Design/methodology/approach
A systematic review of 49 nutritional behaviour intervention programmes (2006–2020) was conducted. To examine the social marketing impact of the programmes, a logic model of social impact was used. The model comprises inputs (the resources used for an intervention programme), outputs (the direct products resulting from the use of resources), outcomes (short- to medium-term programme effects) and impacts (long-term programme effects on the individual, community or societal levels).
Findings
Most intervention programmes set the goal of encouraging their target audience to increase fruit and vegetable intake, choose healthy food items, drink less sugary beverages or consume low-fat diaries, while few others sought policy or systems change. Multiple criteria were used for impact evaluation (e.g. exposure and reach, changes in knowledge, awareness, attitudes, behaviours and body mass index). (Quasi) experiments were the most popular method used for impact measurement, followed by the pre-post model of impact. Positive changes were found in 33 programmes, often reported in terms of short-term outputs or outcomes. Long-term impact particularly on the broader societal level was not indicated.
Originality/value
This research offers a systematic review of how social marketing impact is measured, evaluated and documented. It also provides some guidance for social marketers on how to shift from a reductionist, behavioural outcome-focussed approach towards an “expansionist” impact approach that explicitly considers social marketing impacts on the quality of life of individuals, communities and societies.

Abstract
Purpose
The purpose of this paper is to present an integrated model to measure the operational efficiency of the top 40 container ports in the world for a five-year continuous period using a two-stage uncertainty data envelopment analysis (UDEA) combined with fuzzy C-means clustering method (FCM).
Design/methodology/approach
UDEA model is adopted for measuring the efficiency of container ports to overcome the limitation of the basic model, which is unable to handle uncertain data that are easy to meet in practice. FCM algorithm is implemented to find similar distribution efficiency scores of two stages and the cluster similar efficiency scores of container ports into various groups.
Findings
The combination of the two-stage UDEA model and the FCM algorithm provided a more comprehensive view when evaluating the performance of container ports. The UDEA results show that most of the container ports have reduced their profitability level in the second stage and most of the efficient container ports have turned into inefficient ones because of their small scale.
Originality/value
This paper proposes using the two-stage UDEA model to evaluate port efficiency based on two main aspects of productivity and profitability. Moreover, it combines DEA and FCM algorithms to offer a more comprehensive view when measuring the performance of container ports.

Abstract
Purpose
The purpose of this paper is to explore the prospects of Malaysian seaports as hubs for seaport tourism. This symbiosis nexus between seaports and tourism needs to be explored to provide a luxury economic growth. Combinations of these two segments are expected to explore a new market in Malaysian tourism industry.
Design/methodology/approach
A thorough case study consists of five major seaports in Malaysia including Penang Port, Port Klang, Port of Tanjung Pelepas, Kuantan Port, Bintulu Port and Kota Kinabalu; these seaports have been selected to reveal their opportunities for the prospect of Malaysian seaport tourism via spatial interaction model.
Findings
Four main components including cruise activities, support from intra-region and inter-region economic corridors and the seaport regionalisation can be integrated to reveal the capacity of Malaysian seaport to be hub for seaport tourism.
Originality/value
This paper incorporates tourism sector as one of the streams in the fifth-generation seaports. Seaports and tourism are two economic generators in Malaysia and infusion of these components is expected to enhance the economic prospect, diversify the function of seaports and reduce the over-dependence on conventional tourism activities.

Abstract
Purpose
Vietnam has repositioned itself from a war-torn country to a popular tourist destination. Although research on Vietnam tourism has grown in number, a macro analysis of national tourism governance and policies has largely been missing.
Design/methodology/approach
This synthesis paper offers a systemic analysis of Vietnam’s tourism accommodating intensified government intervention and dramatic market changes in recent decades. The authors offer a chronological analysis of tourism development along with the major political and economic turns of the country.
Findings
The patterns of tourism development reflect a compromise between centralization and decentralization of the governance system and a trade-off between economic and social objectives of development. Balancing these opposites, the internal strength of the domestic market and the resilience of communities and businesses become key assets for growth in circumstances where the socialist market economy continues to inform the current and future development of the industry.
Research limitations/implications
Although the case of Vietnam is unique, the adaptive mechanism of the tourism industry highlighted in this paper offers a useful lesson for other developing countries. The research addresses tourism in the political economy in developing countries, which is valuable for researchers, policy analysts as well as practitioners in tourism.
Practical implications
The practical contribution of the study is derived from authors’ academic and industrial backgrounds. Findings from the study serve as a useful reference for those who embark on the study of tourism governance and policy-making in developing countries and problems associated with the economic transitional process. Those problems of the disparity between centralization and decentralization of the political system might not be only significant in Vietnam, but also prevail in developing countries. Thus, this study offers a point of departure for future empirical and comparative research on the kindship of tourism and political economy in a full scale.
Social implications
The transitional economy as viewed through the tourism industry is prominently presented in the “evolutionary” approach to the transitional economy, which exhibits several unique features: the transition from a centrally planned (command) economy to a market economy and the manifestations of a socialist orientation in the modern economic management system (Vuong et al., 2019). While data from this study is mainly illustrative of the first point, the transition from a planned economy to a market economy, the second characteristic, the manifestation of a social orientation has only slightly been addressed and will need further elaboration in a future study. While Vietnam’s tourism positions itself in a socialist market-oriented economy might set a unique case, the study highlights the politics of tourism is shaped by the politico-economic system. The authors conclude that the adaptation of Vietnam tourism to a socialist market-orientated economy is better perceived as a social evolution achievement rather than a feature of capitalism.
Originality/value
The latest study on tourism governance (Bui et al., 2022) has outlined the evolution of the tourism administrative system and markets in the country; however, linkages of tourism to the broader political economic system have yet to be addressed. Addressing this gap, the authors carry out analysis of policies and governance from the insider’s viewpoint, when team members have been involved in numerous tourism planning and development projects, both on international and national scales. The practical experience along with thorough review of literature and statistical data contributes to shaping a fresh understanding of tourism in a transitional economy.
设计/方法论/途径
这篇综述对越南旅游业进行了系统分析, 包括近几十年来不断增强的政府干预以及巨大的市场变化。作者根据时间顺序分析了旅游业的发展以及该国的主要政治及经济的转变。此外, 政策文件的内容分析及旅游市场分析进一步说明了政治经济体系对旅游治理及政策的影响。
目的
越南已将自己从一个饱受战争的国家重新定位成备受欢迎的旅游目的地。尽管对越南旅游业的研究不断增多, 但对国家旅游治理和政策的宏观分析却被之前的探究所忽略。此研究通过展示越南转型经济中的旅游治理模式连接了两个学科, 并且丰富了政治经济学和旅游学的文献。
研究结果
旅游政策和市场分析反应了治理体系集权与分权之间的折中以及经济和社会发展目标之间的权衡。国内市场的内在优势以及社区及企业的韧性可以成为成长的关键资产来平衡这些对立面, 同时社会主义市场经济将继续影响产业的当前及未来的发展。因此我们的结论是, 越南旅游业适应社会主义市场经济应该被视为社会进化的成就, 而不是资本主义的特征。
研究局限/应用
考虑到一篇文章所能解决的问题有限, 作者无法就转型经济与中国进行比较研究。我们的研究为未来亚洲旅游与政治经济之间联系的实证和比较研究提供了一个出发点。
实践意义
研究结果为发展中国家旅游治理和政策制定研究提供了有益的参考。
社会影响
研究结果对于发展中国家旅游治理及政策制定研究具有重要参考意义。这项研究的成果对于发展中国家的旅游政策分析师, 特别是亚洲的研究人员来说很有价值。
原创性/价值
当前的研究弥补了政治经济学中的一个研究不足, 即马克思主义学说及其与旅游业的对话。知识转移是本研究的一个亮点, 它源自对国家政治经济议程中的旅游治理的批判性分析。
Objetivo
Vietnam ha pasado de ser un país devastado por la guerra a convertirse en un popular destino turístico. Aunque la investigación sobre el turismo en Vietnam ha crecido en número, ha faltado en gran medida un macroanálisis de la gobernanza y las políticas turísticas nacionales. Nuestra investigación ha enriquecido la literatura tanto de la economía política como del turismo tendiendo un puente entre ambas disciplinas al presentar las pautas de la gobernanza del turismo en la economía de transición de Vietnam.
Diseño/metodología/enfoque
Este documento de síntesis ofrece un análisis sistemático del turismo de Vietnam que abarca la intensificación de la intervención gubernamental y los drásticos cambios del mercado en las últimas décadas. Los autores ofrecen un análisis cronológico del desarrollo del turismo junto con los principales giros políticos y económicos del país. Además, el análisis del contenido de los documentos políticos y el análisis del mercado turístico ilustran mejor las repercusiones de los sistemas político-económicos en la gobernanza y las políticas turísticas.
Resultados
Las políticas turísticas y el análisis del mercado revelan un compromiso entre la centralización y la descentralización del sistema de gobernanza y un compromiso entre los objetivos económicos y sociales del desarrollo. Al equilibrar estos opuestos, la fuerza interna del mercado nacional y la resistencia de las comunidades y las empresas se convierten en activos clave para el crecimiento en unas circunstancias en las que la economía de mercado socialista sigue informando el desarrollo actual y futuro de la industria. Concluimos que la adaptación del turismo vietnamita a una economía socialista orientada al mercado se percibe mejor como un logro de la evolución social que como una característica del capitalismo.
Limitaciones/implicaciones de la investigación
Dentro del limitado abanico de cuestiones que podrían abordarse en un solo artículo, los autores no pueden establecer un estudio comparativo con China, en lo que respecta a la economía de transición. Nuestro estudio ofrece un punto de partida para futuras investigaciones empíricas y comparativas sobre la conexión entre turismo y economía política en Asia.
Implicaciones prácticas
Las conclusiones del estudio sirven de referencia útil para quienes se embarcan en el estudio de la gobernanza y la formulación de políticas turísticas en los países en desarrollo.
Implicaciones sociales
Los resultados de la investigación son valiosos para los investigadores del sudeste asiático en particular y para los analistas de la política turística del mundo en desarrollo en general.
Originalidad/valor
La presente investigación contribuye a un área poco investigada de la economía política, a saber, la doctrina marxista y su diálogo con el turismo. La transferencia de conocimientos es un aspecto destacado de esta investigación, que se ha derivado de un análisis crítico de la gobernanza del turismo en la agenda económica política nacional.

Abstract
Purpose
Enhancing sustainable construction supply chain performance is crucial and can be achieved through supply chain integration, eco-design and digital transformation. This study aims to evaluate the impacts of supply chain integration, eco-design and digital transformation on the performance of construction supply chains.
Design/methodology/approach
This study uses the PLS-SEM model to analyze the data collected by survey. Experts’ evaluation also validated the results of the structural model.
Findings
Sustainable supply chain performance in construction projects is significantly impacted by supply chain integration, eco-design and digital transformation. The results also suggest that supply chain integration and eco-design can be enhanced by focusing on digital transformation.
Research limitations/implications
Construction managers can enhance the performance of sustainable construction supply chains. This study contributes to the understanding of sustainable supply chain management in the construction sector, which is consistent with dynamic capacities theory.
Originality/value
Current research has not examined the roles of supply chain integration, eco-design and digital transformation in enhancing sustainable supply chain performance in the construction industry. These roles have been superficially considered in prior studies.

Abstract
Purpose
This research aims to introduce a novel algorithm, the Chaotic Giant Pacific Octopus Optimizer (CGPOO) and demonstrate framework includes four key aspects: time, cost, quality and safety trade-off (TCQST).
Design/methodology/approach
Artificial intelligence is causing a big disruption in the construction management. It is being used to building projects to enhance efficiency, safety and decision-making. This research compared the CGPOO method to those of other algorithms, such as the Chaotic Slime Mold Algorithm (CSMA), the Chaotic Salps Swarm Algorithm (CSSA) and the Chaotic Whale Optimization Algorithm (CWOA) and assessed the efficacy of the method using statistical analysis and evaluation indicators such as Hyper-volumn (HV), Spread (Sp), Computational Time (CT) and C-metric.
Findings
The analysis demonstrates that using CGPOO outperforms standalone methods chosen from the literature in terms of outcomes. It is discovered that the CGPOO solution possibilities for each factors are more efficient and beneficial than the comparison algorithms. Moreover, the CGPOO model performs better than the other algorithms with quality indices C-metric, Sp, HV and CT of 0.534, 0.531, 0.891 and 101.
Originality/value
The article presents a novel hybrid CGPOO that permits multi-factor trade-offs in construction management with the goal of surpassing the analyzed models and optimizing the optimal solution in the search space.

Abstract
Purpose
This research aims to investigate the relationship between value orientations, attitude, behavioral intention and usage behavior of electric ride hailing service in Vietnam through the moderating role of social influences.
Design/methodology/approach
In total, 552 valid questionnaires were collected using the survey questionnaire to analyze the effects of value orientations on attitude toward electric ride hailing and behavioral intention. Besides, this study investigates the mediating effect of attitude toward electric ride hailing and behavioral intention in the relationship with the behavior usage of electric ride hailing service as well as the moderating effect of social influence.
Findings
Three types of value orientations stimulate attitude toward electric ride hailing service and behavioral intention. In addition, attitude toward electric ride hailing service and behavioral intention play the mediating role in the effect of value orientations on behavior usage. Specifically, social influence plays a negative moderating role in the linkage between attitude towards and behavioral intention of electric ride hailing service and between intention and the behavior usage.
Originality/value
While numerous studies have investigated the influence of customers’ value orientations on multiple green purchase behaviors, this study offers new insights into the moderating role of social influence in the linkages between attitude, behavioral intention and usage behavior of electric ride hailing service.

Abstract
Purpose
This study investigates the impact of the European Union-Vietnam Free Trade Agreement (EVFTA) on Vietnam’s labor market and employment outcomes, considering the potential distributional consequences across various groups of workers and regions.
Design/methodology/approach
A comprehensive quantitative framework is employed, combining the gravity model of trade to estimate the EVFTA’s effects on trade flows, the CISAF_M1 model to simulate sectoral employment impacts and econometric models to analyze the effects on wages and decent work. The analysis draws upon a rich dataset spanning the period before and after the EVFTA’s implementation.
Findings
The EVFTA has significantly boosted Vietnam’s exports to the EU, leading to substantial job creation in labor-intensive sectors such as textiles, apparel and footwear. The agreement has also contributed to wage growth and improved access to social insurance for workers in export-oriented industries. However, the impact on other aspects of job quality is less clear. The distributional analysis reveals that the EVFTA’s employment effects have been relatively balanced across gender but have favored younger and less skilled workers as well as those in rural areas.
Originality/value
This study provides a comprehensive and nuanced assessment of the EVFTA’s impact on Vietnam’s labor market, addressing a gap in the literature on the employment effects of new-generation free trade agreements in developing countries. The findings highlight the importance of considering distributional aspects when evaluating the socioeconomic implications of trade liberalization and offer valuable insights for policymakers aiming to promote inclusive growth in the context of deepening international economic integration.

Abstract
Purpose
This study aims to investigate Vietnamese hotel workers’ use of national stereotypes in cross-cultural service encounters. The study extends the existing knowledge on service failures and recovery attempts by illustrating how national stereotypes could inform these decisions through the lens of the script theory.
Design/methodology/approach
In this qualitative study, 34 service providers were interviewed about their experience in dealing with guests from different countries in Vietnamese hotels.
Findings
Service providers categorised guests based on their countries of origin to predict their behaviour prior to guest arrivals. When the guest’s behaviour matches the expectations, the service encounters went smoothly by following existing scripts. If there is a discrepancy between the guest behaviours and expectations, it could lead to service failure and the need for new scripts. Appropriate interventions in this process could turn anecdotes into accumulated understanding of guest behaviour for better service and guest experience as a new application of national stereotypes.
Originality/value
This study advances cross-cultural service encounter research by integrating national stereotypes and script theory. It sheds new light on how national stereotypes could inform service delivery and recovery attempts in service organisations.
目的
本研究旨在调查越南酒店员工在跨文化服务遭遇中使用民族刻板印象的情况。研究通过脚本理论的视角阐释了国家的刻板印象如何为这些决定提供信息, 扩展了现有的服务失败和恢复尝试的知识。
设计/方法
在这项定性研究中, 采访了34家服务提供商, 了解他们在越南酒店与来自不同国家的客人打交道的经历。
调查结果
服务提供商根据客人的原籍国对他们进行分类, 以预测他们在客人抵达前的行为。当客人的行为符合预期时, 通过遵循现有脚本, 服务接触会顺利进行。如果客人的行为和期望之间存在差异, 可能会导致服务失败, 并需要新的脚本。作为国家刻板印象的新应用, 在这一过程中进行适当的干预可以将轶事转化为对客人行为的累积理解, 以提供更好的服务和客人体验。
独创性/价值
本研究通过整合民族刻板印象和脚本理论, 推进跨文化服务遭遇研究。它揭示了在服务组织中, 国家的刻板印象如何影响服务提供和恢复尝试。
Objetivo
Este estudio tiene como objetivo investigar el uso de los estereotipos nacionales por parte de los trabajadores hoteleros vietnamitas en el encuentro intercultural de servicios. El estudio amplía el conocimiento existente sobre los fallos en el servicio y los intentos de recuperación al ilustrar cómo los estereotipos nacionales podrían influir en estas decisiones a través de la teoría del guion.
Diseño/metodología/enfoque
En este estudio cualitativo, se entrevistó a 34 proveedores de servicios sobre su experiencia en el trato con huéspedes de diferentes países en hoteles vietnamitas.
Resultados
Los proveedores de servicios clasificaron a los huéspedes en función de sus países de origen para predecir su comportamiento antes de su llegada. Cuando el comportamiento de los huéspedes coincide con las expectativas, los encuentros con el servicio se desarrollaron sin problemas siguiendo los guiones existentes. Si hay una discrepancia entre los comportamientos y las expectativas de los huéspedes, podría provocar un fallo en el servicio y la necesidad de nuevos guiones. Las intervenciones consideradas apropiadas en este proceso podrían convertir las anécdotas en una comprensión acumulada del comportamiento de los huéspedes, lo cual mejoraría el servicio y la experiencia de los huéspedes como una nueva aplicación de los estereotipos nacionales.
Originalidad/valor
Este estudio avanza en la investigación de encuentros de servicio interculturales mediante la integración de estereotipos nacionales y la teoría del guion. Además, arroja nueva luz sobre cómo los estereotipos nacionales podrían influenciar la prestación de servicios y los intentos de recuperación en las organizaciones de servicios.
