Abstract
Purpose
Class-based storage has been studied extensively and proved to be an efficient storage policy. However, few literature addressed how to cluster stuck items for class-based storage. The purpose of this paper is to develop a constrained clustering method integrated with principal component analysis (PCA) to meet the need of clustering stored items with the consideration of practical storage constraints.
Design/methodology/approach
In order to consider item characteristic and the associated storage restrictions, the must-link and cannot-link constraints were constructed to meet the storage requirement. The cube-per-order index (COI) which has been used for location assignment in class-based warehouse was analyzed by PCA. The proposed constrained clustering method utilizes the principal component loadings as item sub-group features to identify COI distribution of item sub-groups. The clustering results are then used for allocating storage by using the heuristic assignment model based on COI.
Findings
The clustering result showed that the proposed method was able to provide better compactness among item clusters. The simulated result also shows the new location assignment by the proposed method was able to improve the retrieval efficiency by 33 percent.
Practical implications
While number of items in warehouse is tremendously large, the human intervention on revealing storage constraints is going to be impossible. The developed method can be easily fit in to solve the problem no matter what the size of the data is.
Originality/value
The case study demonstrated an example of practical location assignment problem with constraints. This paper also sheds a light on developing a data clustering method which can be directly applied on solving the practical data analysis issues.

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
Vietnam is an emerging economy in the South East Asia region. Its Generation Z is gradually taking the lead in the country. But rather than breaking away from the previous generations, this generation also shows a strong preference towards local values and solid commitment to social issues. Thus, traditional culture elements are increasingly integrated in every aspect of Generation Z’s life, such as advertising and fashion. Instead of hanging out at coffee places, they go for bubble tea. They still appreciate the traditional values but integrate them within a modern context. Brands chase after these young people by adapting their values into their products and services. In the work place, the Vietnamese Generation Z is less confident. They are partially lost in career development with poor career counselling in the education system. They desire new experience and new learning opportunities. Generation Z, who were born beginning in 1995, emerges in Vietnam as a fresh and promising force.

Abstract
Purpose
The purpose of this paper is to investigate the factors affecting innovative behavior (IB) of Vietnamese enterprises employees based on theories of transformational leadership, social cognitive and knowledge spiral.
Design/methodology/approach
This study used a combination of in-depth interviews and large-scale surveys in 15 enterprises in the North, Central and South of Vietnam. In total, 455 valid questionnaires from employees of information technology, telecommunications and e-commerce enterprises have been used in this research to explore the impact of transformational leadership (TL), coworker support (CS) and organizational learning (OL) on employees' IB. The data collected were subjected to quantitative analysis, including Cronbach's alpha reliability test, exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modeling (SEM) for scales and hypotheses testing.
Findings
The results show that there are positive relationships between TL, OL and employees' IB, in which OL has a stronger impact than TL.
Research limitations/implications
The limitations of this paper are that other factors affecting the innovation behavior of employees in Vietnamese enterprises have not been fully explored, the rejection of the hypothesis about the relationship between CS and employees’ IB needs to be considered with the moderating role of job characteristics and the use of convenient random sample selection, due to which its reliability may not be guaranteed.
Practical implications
From the results of this study, the authors point out that managers in Vietnamese enterprises should develop TL to deliver more creativity in an organization and enhance the corporate learning-oriented environment.
Originality/value
This paper contributes to the existing literature by focusing on factors affecting IB of enterprises employees in Vietnam, an emerging economy in the world.

Abstract
Purpose
Among others in South Vietnam, the Temple of Literature in Vinh Long is the only one that has preserved its original form and layout. As such in 1991, the temple was recognized by the Ministry of Culture as a national-level historical and cultural relic. Nevertheless, the temple has been neither studied nor documented to any great depth. Only a few historical descriptions for local tour guidebooks and photo catalogs exist. Therefore this paper aims to initially record heritage values, spatial characteristics and the process of major changes, while documenting the current state of the temple structure and carrying out on-site inspections to survey the buildings.
Design/methodology/approach
This paper outlines the collection of survey data through field survey and provides an overview of the existing significant heritage factors of the Temple of Literature in Vinh Long by comparative examination in relation to other surviving temples and analyzing its unique spatial characteristics and indigenous cultural decorations in detail.
Findings
Although the layout of the temples was influenced by the Chinese Confucius's principles and the notion of Feng Shui, it is evident from the study that the design of the temple has many architectural elements that reveal Vietnam's unique culture and local features. In particular, the Temple of Literature in Vinh Long was a symbol of feudal education, symbolizing sacred traditional values in the field of education for the people of Vinh Long province. Stone steles recorded names of all contributors related to the construction and restoration of the temple with sincere gratitude. Moreover, many of the decorative motifs contain many indigenous cultural and artistic values of Vietnam, reflecting traditional Vietnamese beliefs and ethnographic features.
Research limitations/implications
By comparatively analyzing the temple with others, it reveals the unique spatial features, layouts, changes and evolutions of the temple. Unlike the oldest and the largest Temple of Literature in Hanoi, the temples in the South are much smaller in terms of complex sizes and the number of buildings. They are mostly composed of a singular structure, the Attained Talent House, with some basic gates and water features interwoven within the landscape of the site. Based on the elementary layout, some subsidiary buildings were added according to the needs and site conditions, and in accordance with the bilateral axis.
Social implications
The awareness and preservation of the architectural features of the local temple are needed to protect heritage monuments and to enhance cultural resources as part of securing Vietnamese ideology for a longer period of time. While the interest in historic preservation and conservation activities of heritage buildings in Vietnam has slowly grown in attention over the last decade, it is evident that many opportunities remain. It is hoped that this research is a small step toward further research, education and advocacy in the preservation of historic buildings in Vietnam.
Originality/value
The introduction of Chinese Confucian thought to Vietnam was one of the most substantial influences in Vietnamese intellectual history. Despite being an important part of the nation's architectural, cultural and intellectual heritage sites, the study and documentation of the Temples of Literature have been relatively neglected or marginalized. Accordingly, this study is significant to reveal not only the values and unique heritage characteristics of the temple, but also to prioritize resources for continued study and preservation.

Abstract
Purpose
Drawing from agency and comprehension theories, this paper aims to examine the influence of annual report readability (ARR) on financial reporting quality (FRQ), with a focus on how information asymmetry moderates this relationship.
Design/methodology/approach
The study uses a sample of 467 listed firms in Vietnam from 2015 to 2021. To analyze the relationship between ARR and FRQ, this paper employs a Generalized Method of Moments (GMM) regression, incorporating information asymmetry as a moderating factor.
Findings
The research findings show that ARR has a positive and significant impact on the FRQ of Vietnamese-listed firms. This paper also finds that information asymmetry significantly and partially moderates the relationship between ARR and FRQ. Specifically, ARR can help alleviate the level of information asymmetry and contributes to improved FRQ.
Practical implications
From a practical perspective, this paper provides empirical evidence for managers, investors and related government departments to evaluate the effects of ARR and offers regulators a method to help improve the transparency of the stock market. More importantly, the results of this study have reference value for scholars and practitioners in developing countries like Vietnam.
Originality/value
From a theoretical perspective, our study adds to the growing literature on ARR, expands the scope of ARR research, elaborates on relevant economic consequences of ARR and complements the literature on the determinants of FRQ.

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.
