Abstract
Purpose
This study applies the target similarity model to examine the effects of servant leadership on supervisor commitment and supervisor citizenship behavior. The mediating role of supervisory commitment is explored to determine the relationship between servant leadership and supervisor citizenship behavior. The difference in supervisor gender is examined in the linkage between servant leadership and supervisory commitment.
Design/methodology/approach
The data were collected through a survey of 478 salespeople in the retail industry. Structural equation modeling (SEM) techniques were used to verify the hypotheses of this study.
Findings
The findings showed significant support for the direct and indirect effects of servant leadership on supervisor commitment and supervisor citizenship behavior. Furthermore, the positive relationship between servant leadership and supervisory commitment was stronger among female supervisors than male supervisors.
Originality/value
Due to the scarcity of studies conducted on the linkages of servant leadership, supervisory commitment and supervisory citizenship behavior, this study theoretically and empirically contributes to the leadership literature as it is the first study to investigate these direct and indirect relationships. Similarly, this study examined gender differences in servant leadership to fill the gap in the research field.

Abstract
Purpose
Large collections of patent documents disclosing novel, non-obvious technologies are publicly available and beneficial to academia and industries. To maximally exploit its potential, searching these patent documents has increasingly become an important topic. Although much research has processed a large size of collections, a few studies have attempted to integrate both patent classifications and specifications for analyzing user queries. Consequently, the queries are often insufficiently analyzed for improving the accuracy of search results. This paper aims to address such limitation by exploiting semantic relationships between patent contents and their classification.
Design/methodology/approach
The contributions are fourfold. First, the authors enhance similarity measurement between two short sentences and make it 20 per cent more accurate. Second, the Graph-embedded Tree ontology is enriched by integrating both patent documents and classification scheme. Third, the ontology does not rely on rule-based method or text matching; instead, an heuristic meaning comparison to extract semantic relationships between concepts is applied. Finally, the patent search approach uses the ontology effectively with the results sorted based on their most common order.
Findings
The experiment on searching for 600 patent documents in the field of Logistics brings better 15 per cent in terms of F-Measure when compared with traditional approaches.
Research limitations/implications
The research, however, still requires improvement in which the terms and phrases extracted by Noun and Noun phrases making less sense in some aspect and thus might not result in high accuracy. The large collection of extracted relationships could be further optimized for its conciseness. In addition, parallel processing such as Map-Reduce could be further used to improve the search processing performance.
Practical implications
The experimental results could be used for scientists and technologists to search for novel, non-obvious technologies in the patents.
Social implications
High quality of patent search results will reduce the patent infringement.
Originality/value
The proposed ontology is semantically enriched by integrating both patent documents and their classification. This ontology facilitates the analysis of the user queries for enhancing the accuracy of the patent search results.

Abstract
Unsustainable logging and illegal logging for domestic and international trade and trafficking continue to lead to deforestation. It is crucial that Sustainable Development Goal 15 ‘Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss’ is achieved to maintain the livelihoods of people and protect the planet. This is the case in Vietnam as well, where many people, including indigenous groups, rely on the forest for their survival. Drawing on semistructured interviews in Vietnam and a literature review, we investigate how the abuse of forest policies leads to human insecurity. From this, we propose solutions to (1) end unsustainable harvesting and illegal logging (SDG 15.7), (2) integrate the value of forests (culturally and economically) into national and local planning, the development process and poverty elimination strategies (SDG 15.9) and (3) improve the use of forest protection funding provided by international donors.

Abstract
Purpose
On the basis of the conservation of resources theory (CORT), this study investigates the relationship between social overload and users’ withdrawal intention from social communities on social networking sites (SNSs), with the serial mediating mechanisms of social-psychological distance and emotional exhaustion and the moderating mechanism of (similar) linguistic style.
Design/methodology/approach
Data were collected from 489 users in different social communities on SNSs in an emerging market. Structural equation modeling was used to analyze the sample data and test the hypotheses.
Findings
Results show that social overload has a positive influence on withdrawal intention from social communities on SNSs. Furthermore, social-psychological distance and emotional exhaustion have a serial mediating effect in this relationship. In addition, (similar) linguistic style negatively moderates the link between social overload and emotional exhaustion and that between social overload and withdrawal intention.
Originality/value
This study extends CORT to propose and test a unique research model that clarifies the mechanisms leading to users’ withdrawal behavior from social communities on SNSs. The findings of this study provide implications for researchers, individual users, administrators/managers of social communities, and SNS providers to understand and make better decisions to retain member users.

Abstract
Purpose
This study is based on the regulatory focus theory and conservation of resources theory to examine how information confusion leads to users’ discontinuous usage intention of social networking sites (SNSs), with the mediating mechanisms of users’ motivation and affectivity.
Design/methodology/approach
Data were obtained from 270 users in different SNSs in Vietnam. Structural equation modeling was used to analyze the sample data and test the hypotheses.
Findings
Results show that information confusion has a positive influence on discontinuous usage intention, and prevention focus positively mediates this relationship. Furthermore, the negative affectivity positively mediates the link between information confusion and discontinuous usage intention and that between prevention focus and discontinuous usage intention. In addition, prevention focus and negative affectivity together play a serial mediating effect in the link between information confusion and discontinuous usage intention.
Originality/value
This study extends the regulatory focus theory and conservation of resources theory to validate a model that explains the transitional process of users’ motivation and affectivity in the link between information confusion and discontinuous usage intention of SNSs. The findings of this study provide implications for academic researchers and business managers of SNSs to understand and make better decisions to retain their users.

Abstract
This paper focuses on dry port as a key notion in port-hinterland development. We first discuss the concept of dry port by reviewing existing literature. Then, we explore the reasons behind the emergence and development of inland node systems in different geographical, economic and institutional contexts. Next, the paper presents a classification of dry ports based on a multitude of factors and dimensions and the respective benefits to different parties. The study then focuses on the specific characteristics of dry ports and associated transport networks in developing countries.
In the last part, we present a case study on the dry port system in Vietnam by reviewing the seaport and inland transport system and analyzing the current status of inland terminals in Vietnam. To conclude, a SWOT analysis is presented with regard to the development of the dry port network in Vietnam, followed by recommendations for policy makers.

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
Despite the potential of artificial intelligence (AI) systems to increase revenue, reduce costs and enhance performance, their adoption by organisations has fallen short of expectations, leading to unsuccessful implementations. This paper aims to identify and elucidate the factors influencing AI adoption at both the organisational and individual levels. Developing a conceptual model, it contributes to understanding the underlying individual, social, technological, organisational and environmental factors and guides future research in this area.
Design/methodology/approach
The authors have conducted a systematic literature review to synthesise the literature on the determinants of AI adoption. In total, 90 papers published in the field of AI adoption in the organisational context were reviewed to identify a set of factors influencing AI adoption.
Findings
This study categorised the factors influencing AI system adoption into individual, social, organisational, environmental and technological factors. Firm-level factors were found to impact employee behaviour towards AI systems. Further research is needed to understand the effects of these factors on employee perceptions, emotions and behaviours towards new AI systems. These findings led to the proposal of a theory-based model illustrating the relationships between these factors, challenging the assumption of independence between adoption influencers at both the firm and employee levels.
Originality/value
This study is one of the first to synthesise current knowledge on determinants of AI adoption, serving as a theoretical foundation for further research in this emerging field. The adoption model developed integrates key factors from both the firm and individual levels, offering a holistic view of the interconnectedness of various AI adoption factors. This approach challenges the assumption that factors at the firm and individual levels operate independently. Through this study, information systems researchers and practitioners gain a deeper understanding of AI adoption, enhancing their insight into its potential impacts.

Abstract
Purpose
The purpose of this paper is to review both international and domestic (i.e. Vietnamese language) journal articles and graduate theses and dissertations on educational leadership in Vietnam. The review addresses two specific goals: first, to describe and critically assess the nature of the formal knowledge base on principal leadership in Vietnam, second, to synthesize findings from the existing literature on principal leadership in Vietnam.
Design/methodology/approach
The paper employed a method for conducting systematic reviews of research. The authors conducted a detailed, exhaustive search for international and “local” papers from Vietnam, yielding 120 research sources. Information from these papers was extracted and evaluated prior to analysis. Data analysis included both quantitative description of the “review database” as well as critical synthesis of substantive findings.
Findings
The review supports and extends an earlier review which found that the practice of educational leadership in Vietnam remains largely “invisible” to the international community of scholars. The review also yielded a highly critical assessment of research perspectives and methods used in the “local” Vietnamese studies which comprised the bulk of the authors’ database. Synthesis of substantive findings highlighted the manner by which organizational, political, and socio-cultural forces in the Vietnamese context shapes the practice of school leadership.
Research limitations/implications
First, qualitative studies are recommended that seek to describe, in-depth, the enactment of leadership in the Vietnamese context. Second, broad-scale surveys of characteristics, attitudes, and beliefs of school leaders across Vietnam are warranted. Third, the authors encourage graduate students and scholars studying school leadership in Vietnam to undertake a new generation of theory-informed studies that connect with the global literature.
Practical implications
Due to the relatively weak nature of the existing knowledge base, the authors were unable to identify specific implications for leadership practice. However, practical implications are identified for developing the research capacity needed to improve research quality in Vietnam’s universities.
Originality/value
This review is the first systematic review of educational leadership and management conducted of the Vietnamese literature. Moreover, the authors suggest that the review is original in its comprehensive coverage of both the local and international literature on educational leadership in Vietnam.
