Abstract
Purpose
This paper presents the outcomes of the international project “Protecting Landscape Heritage: a requalification project as an instrument for the re-birth of Quang Tri Old Citadel in Vietnam”, achieved with scientific cooperation between the Università Politecnica delle Marche (Italy) and Hue University of Sciences (Vietnam) funded by the Italian Ministry of Foreign Affairs and International Cooperation and Ministry of Science and Technology of Vietnam. The research focuses on the Quang Tri Citadel, founded in 1809 and now in an advanced state of degradation.
Design/methodology/approach
For the purpose of rehabilitation, the wide multidisciplinary project first examined the historical context of the military model, the architectural aspects of the structure, the characterization of the existing materials, the degradation levels of different parts, and, finally, a proposal of the suggested interventions.
Findings
The original structure and geometry were extrapolated and studied. Building materials were produced with nearby raw materials. Firing temperatures of bricks ranged from 800 to 1,000 °C, hydraulic lime was supposed the binder of the mortar with a calcination temperature lower than 1,000 °C. Damage assessment was provided and after these analyses a requalification project was proposed so the cultural heritage can play a role for the future in the dialog between different cultures.
Originality/value
The requalification project achieved by an integrated analytical approach defines aspects in relation to the restoration of the structures, enabling compliance with the geometry, techniques, building materials used in the original construction and allowing its guardianship and management to align with the historical context of the architectural heritage.

Abstract
Purpose
Service quality has been widely recognized as the core value of any higher education institution (HEIs), especially in the context of higher education reform in Vietnam. The paper aims to assess the student’s perceived service quality using SERVPERF scale and to find the relations between perceived service quality, satisfaction and loyalty in one public university in Vietnam.
Design/methodology/approach
The self-structured questionnaire using SERVPERF scale was administered to 350 students currently attending full-time courses at the university. Confirmatory factor analysis was used to certify the elementary factors. The regression models were applied to determine the relationship between service quality, student satisfaction and student loyalty.
Findings
The findings revealed the significant relationships between student perceived service quality with satisfaction and loyalty. However, this relationship is mediated by student satisfaction.
Research limitations/implications
The study is limited to public university education service and examined the perspective of student as “primary customer”; therefore, generalizing the results to other service industries and other role of student as stakeholder or citizen should be used with caution.
Practical implications
The SERVPERF scale could be delivered regularly to get the student’s perception on the HEIs performance. The results should be taken for purpose of continuing quality improvement to enhance the satisfaction and loyalty, particularly in the context of highly competitive environment and university autonomous in Vietnam.
Originality/value
This is believed to be the first study in Vietnam with sufficient evidence to support the concept that service quality positively related to students’ satisfaction and loyalty and satisfaction as mediating factor.

Abstract
Purpose
While the application of blockchain technology in the organic food supply chain has been increasingly recognized, the extant knowledge of how blockchain-driven traceability influences consumer perceptions and purchase intentions remains underexplored. Grounded in the stimulus-organism-response theory, this study aims to construct a moderated mediation model to examine blockchain-enabled traceability’s direct and indirect impacts on organic food purchase intention through perceived blockchain-related information transparency, considering the moderating role of blockchain-based trust.
Design/methodology/approach
A purposive sample of 5,326 Vietnamese consumers was surveyed using the PROCESS macro to test the proposed hypotheses.
Findings
The findings indicate that blockchain-enabled traceability significantly enhances perceived blockchain-related information transparency, which positively influences organic food purchase intention. Furthermore, blockchain-based trust was found to positively moderate both the direct effect of transparency on purchase intention and the indirect impact of traceability on purchase intention through transparency.
Practical implications
Practical and managerial insights for stakeholders in the organic food sector are also discussed.
Originality/value
These results contribute to the literature by extending the stimulus-organism-response model to the context of blockchain technology in supply chains and highlighting the critical role of trust in moderating the effectiveness of technological innovations.

Abstract
Purpose
This study aims to redefine the urban heritage value of trade streets in Hanoi's Ancient Quarter (AQ) and propose an expanded notion of the “historicity” found through intangible cultural heritage (ICH).
Design/methodology/approach
A longitudinal analysis was conducted to examine the historical transitions of trade streets, thereby providing an alternative value perspective for considering the area's conservation management. The trade streets were specifically analysed from the pre-colonial era to 2017 using past survey data concerning the distribution and concentration of trade types, statistical documents from the colonial era and recent fieldwork data from investigations into 79 trade streets, thus identifying seven patterns of change.
Findings
Individual trade streets contribute to the unique identities of their respective streets while collectively providing experiential value through the overall variety and density of trade types. Further, the value of modernised trade streets can be found in their support of the area's systemic and experiential values.
Practical implications
Current management approaches should shift to include non-traditional trade streets that have experienced gradual changes or retained specific businesses for long periods of time.
Originality/value
This was the first study to conduct a longitudinal analysis of AQ trading with partial support from statistical data. It explored an expanded way of interpreting historicity from the viewpoint of dynamic ICH along the two axes of pace and intensity by tracing changes in commercial activities over time.

Abstract
Purpose
This research applies the stimulus-organism-behavior-consequence framework to explore how blockchain-enabled traceability influences trust in organic food producers and retailers, which impacts consumers’ purchase behaviors and subsequent outcomes.
Design/methodology/approach
Using a purposive sample of 5,326 Vietnamese consumers, multiple linear and polynomial regression with response surface analysis were employed to examine the hypotheses.
Findings
Blockchain-enabled traceability significantly enhances trust in both producers and retailers, which congruently and incongruently influences organic food purchase behaviors. This behavior also drives consumers’ word-of-mouth and repurchase intentions. Serial mediation analysis confirms blockchain’s impact through trust and purchase behaviors.
Research limitations/implications
Stakeholders should adopt blockchain to boost transparency and trust, which increases consumer engagement. Policymakers can support this transition through regulations and incentives to enhance food security and sustainability.
Originality/value
This study expands on blockchain research by applying the stimulus-organism-behavior-consequence framework in the organic food supply chain, showing how blockchain-enhanced trust synergistically affects consumers’ purchase behaviors, word-of-mouth and repurchase intentions.

Abstract
Purpose
This paper aims to provide designers/engineers, in engineering structural design and analysis, approaches to freely and accurately modify structures (geometric and/or material), and then quickly provide real-time capability to obtain the numerical solutions of the modified structures (designs).
Design/methodology/approach
The authors propose an isogeometric independent coefficients (IGA-IC) method for a fast reanalysis of structures with geometric and material modifications. Firstly, the authors seamlessly integrate computer-aided design (CAD) and computer-aided engineering (CAE) by capitalizing upon isogeometric analysis (IGA). Hence, the authors can easily modify the structural geometry only by changing the control point positions without tedious transformations between CAE and CAD models; and modify material characters simply based on knots vectors. Besides, more accurate solutions can be obtained because of the high order degree of the spline functions that are used as interpolation functions. Secondly, the authors advance the proposed independent coefficients method within IGA for fast numerical simulation of the modified designs, thereby significantly reducing the enormous time spent in repeatedly numerical evaluations.
Findings
This proposed scheme is efficient and accurate for modifying the structural geometry by simply changing the control point positions, and material characters by knots vectors. The enormous time spent in repeated full numerical simulations for reanalysis is significantly reduced. Hence, enabling quickly modifying structural geometry and material, and analyzing the modified model for practicality in design stages.
Originality/value
The authors herein advance and propose the IGA-IC scheme. Where, it provides designers to fasten and simple designs and modify structures (both geometric and material). It then can quickly in real-time obtain numerical solutions of the modified structures. It is a powerful tool in practical engineering design and analysis process for local modification. While this method is an approximation method designed for local modifications, it generally cannot provide an exact numerical solution and its effectiveness for large modification deserves further study.
