Abstract
Purpose
Corporations and their leaders are coming under increasing pressure to achieve “sustainability.” Sustainable enterprises minimize harmful environmental impacts, are socially responsible, and create shareholder value.
Design/methodology/approach
Using secondary data, we compared the financial performance of recognized sustainability leaders to that of a carefully selected matched set of competitors.
Findings
The authors find that, on average, sustainability leaders outperform their competitors. However, this is true and only two out of three cases.
Research limitations/implications
While the authors utilized a relatively small sample with data that covers only a three‐year period, the use of secondary data from two different databases reduces concerns about common method bias. The clear implication of this analysis is that a commitment to sustainability does not harm financial performance and may, in fact, enhance performance.
Practical implications
The authors conclude with a set of recommendations for how top management teams can hit the sustainability sweet spot.
Originality/value
The concept of the sustainable enterprise is relatively new and little rigorous research has been conducted on its performance implications. The authors believe that the literature review, the research undertaken, and the practical implications will be of value to both scholars and to executive teams.

Abstract
Purpose
Drawing on social exchange theory, this paper aims to clarify the influences of ethical leadership (EL) on knowledge-sharing (KS) behaviours of employees through the mediating roles of affective- and cognitive-based trust in leadership. This work further offers deeper insight into the moderating mechanism of distributive justice in the EL–KS relationship.
Design/methodology/approach
Structural equation modelling (SEM) is used to investigate the influential degree of EL, aspects of employee trust in leadership and distributive justice on employee behaviours towards tacit and explicit knowledge via data collected from 339 participants in 75 Vietnamese firms.
Findings
The empirical findings reveal that employee trust in leadership positively mediates the relationship between EL and KS behaviours. In particular, distributive justice significantly fosters the impacts of EL on tacit and explicit KS behaviours.
Practical implications
Managers and practitioners should strengthen EL practices to build and maintain employee trust in them for promoting KS behaviours. In addition, research highlights the necessity of establishing distributive justice in organisations to enhance the effect of EL on KS behaviours of employees.
Originality/value
This paper is unique in its attempts to advance the insights on the theory of leadership and knowledge management by investigating the different moderated-mediation mechanisms in the relationship between EL and specific aspects of KS behaviours.

Abstract
Purpose
Due to the vital role of innovation for firms to respond to the change and achieve competitive advantage, the purpose of this study is to investigate the influence of knowledge-oriented leadership (KOL) on innovation performance via the mediating role of knowledge sharing (KS). This study also explores the moderating role of organizational justice in the relationship between KS and innovation performance.
Design/methodology/approach
Analysis of moment structures and structural equation modeling are applied to examine the relationship among the latent factors in the proposed research model using data collected from 335 participants in 121 manufacturing and service firms in Vietnam.
Findings
The findings revealed that KOL serves as a key precursor to foster innovation performance directly or indirectly through active and passive KS behaviors. In addition, the paper highlights the moderating role of organizational justice in strengthening the impact of KS activities on innovation performance.
Research limitations/implications
By highlighting the important role of KOL for stimulating KS behaviors, this paper provides a valuable understanding and novel approach for firms to improve innovation performance. The research findings support the idea that building a climate of justice is crucial to enhance the effects of KS on innovation performance.
Originality/value
This study contributes to bridging the research gaps in the literature and advances the insights of how KOL directly and indirectly stimulates innovation performance via mediating roles of active and passive KS processes under the climate of justice.

Abstract
Purpose
The purpose of this paper is to expand and analyze deeply customer emotions, concretize the levels of positive or negative emotions with the aim of using machine learning methods, and build a model to identify customer emotions.
Design/methodology/approach
The study proposed a customer emotion detection model and data mining method based on the collected dataset, including 80,593 online reviews on agoda.com and booking.com from 2009 to 2022.
Findings
By discerning specific emotions expressed in customers' comments, emotion detection, which refers to the process of identifying users' emotional states, assumes a crucial role in evaluating the brand value of a product. The research capitalizes on the vast and diverse data sources available on hotel booking websites, which, despite their richness, remain largely unexplored and unanalyzed. The outcomes of the model, pertaining to the detection and classification of customer emotions based on ratings and reviews into four distinct emotional states, offer a means to address the challenge of determining customer satisfaction regarding their actual service experiences. These findings hold substantial value for businesses operating in this domain, as the findings facilitate the evaluation and formulation of improvement strategies within their business models. The experimental study reveals that the proposed model attains an exact match ratio, precision, and recall rates of up to 81%, 90% and 90%, respectively.
Research limitations/implications
The study has yet to mine real-time data. Prediction results may be influenced because the amount of data collected from the web is insufficient and preprocessing is not completely suppressed. Furthermore, the model in the study was not tested using all algorithms and multi-label classifiers. Future research should build databases to mine data in real-time and collect more data and enhance the current model.
Practical implications
The study's results suggest that the emotion detection models can be applied to the real world to quickly analyze customer feedback. The proposed models enable the identification of customers' emotions, the discovery of customer demand, the enhancement of service, and the general customer experience. The established models can be used by many service sectors to learn more about customer satisfaction with the offered goods and services from customer reviews.
Social implications
The research paper helps businesses in the hospitality area analyze customer emotions in each specific aspect to ensure customer satisfaction. In addition, managers can come up with appropriate strategies to bring better products and services to society and people. Subsequently, fostering the growth of the hotel tourism sector within the nation, thereby facilitating sustainable economic development on a national scale.
Originality/value
This study developed a customer emotions detection model for detecting and classifying customer ratings and reviews as 4 specific emotions: happy, angry, depressed and hopeful based on online booking hotel websites agoda.com and booking.com that contains 80,593 reviews in Vietnamese. The research results help businesses check and evaluate the quality of their services, thereby offering appropriate improvement strategies to increase customers' satisfaction and demand more effectively.

Abstract
Purpose
The purpose of this paper is to investigate the input- and output-specific technical inefficiency of Vietnamese prawn-rice rotational crops (PRRC) and to identify the impacts of the socio-economic characteristics of farmers and farms on these technical inefficiencies.
Design/methodology/approach
This study first used a Russell-type (input-output) directional distance function to estimate the input- and output-specific technical inefficiency. Second, it applied a bootstrap truncated regression to analyze the factors influencing these technical inefficiencies. Data were gathered through a survey among 94 farmers, from Ben Tre and Kien Giang provinces, the two popular PRRC areas in the Mekong Delta.
Findings
Results show that Vietnamese PRRC farmers could reduce the water surface area by 3%, the use of seedlings by 15%, labor by 16%, fertilizers by 26%, and the use of others by 24%, while simultaneously increasing the revenue of farming system by 57% relative to the variable returns to scale (VRS) frontier. Farmers with more years of experience are generally better in managing the use of seedlings and in improvement of revenue. Farmers in Kien Giang province are more efficient in achieving revenue of the PRRC farming system than farmers in Ben Tre province.
Research limitations/implications
Outcomes of this study are useful to identify strategies in minimizing the use of inputs while simultaneously maximizing PRRC production.
Originality/value
This paper relates to the comparison of two mostly different ecological zones, being the dominant production areas of PRRC, in which, Kien Giang represents the western part, while Ben Tre is in the eastern part of the Vietnam’s Mekong Delta. The findings not only expand the current understanding but also suggest various meaningful research questions regarding the development of Vietnamese PRRC under the impacts of climate change. The study also contributes to the literature on examining the input- and output-specific technical inefficiencies and influencing factors.

Abstract
“The world needs science, science needs women” is the message given by UNESCO in the program for the development of women in science” (UNESCO, 2017). In Vietnam, women’s participation and achievements in scientific research is considered a great and important resource for industrialization and modernization. Even so, are there gender differences in scientific achievement in the social science research institutes in Vietnam? What factors influence the scientific achievement of female social researchers? The answers will be based on data from a 2017 survey with a sample of 756 researchers, of which 77.6% were female. The survey was conducted by the Vietnam Academy of Social Sciences, a leading, ministry-level national center for the social sciences in Vietnam. This chapter analyzed the scientific achievements of researchers through their position as principal investigators of research projects and their publications, and factors that may impact this. Bivariate and multivariate analyses of factors that may affect the scientific achievement of researchers found that gender differences in academic achievement in the social sciences in Vietnam was still prevalent. Female researchers’ scientific achievements were lower than those of their male counterparts. The contribution to science of Vietnamese female researchers was limited by many different factors; the most important were the academic rank of the researchers and gender stereotype that considered housework the responsibility of women.

Abstract
Purpose
The growth of self-service technologies (SST) in the retail sector has led to an increased prevalence of SST failures, and spurred academic debate on customer self-recovery of the failed services. This study sets out to explore why customers prefer or decline to engage in self-recovery. A framework integrating elements from self-determination theory and theory of planned behavior is developed to explore the impact of motivational factors, attitudes and self-efficacy on self-recovery intention.
Design/methodology/approach
Structural equation modeling (SEM) was used to analyze the sample consisting of 297 users of retail kiosks in convenience stores.
Findings
The results revealed that intrinsic motivation and identified regulation directly affect customers' attitude and intention to engage in self-recovery. Despite an insignificant direct relationship, external regulation impacted self-recovery intention through attitude. Further, the association between intrinsic motivation and self-recovery intention is moderated by self-efficacy.
Originality/value
Much of the extant SST recovery literature has focused on company-rendered service recovery, providing little guidance to firms on how to promote self-recovery among customers. The integrated motivational-cognitive theoretical base in this study allows for a more differentiated inquiry into the factors shaping self-recovery intention, resulting in a deeper understanding of this topic. The novel insights will help retailers develop effective strategies for promoting self-recovery among users of retail kiosks.

Abstract
Purpose
The outbreak of the COVID-19 pandemic has led to the pervasiveness of food delivery apps (FDAs) and the increased scholars’ attention for the topic of FDA continuance usage intention. However, the limited understanding about possible segments of FDA users has hindered food retailers from providing FDAs with a personalized manner, which impairs the effectiveness of marketing strategies. Thus, this study aims to first explore key antecedents of users’ continuance intention toward FDAs and then segment and profile Taiwanese users based on the identified antecedents of FDA continuance intention and demographics.
Design/methodology/approach
An online survey was implemented to collect responses from FDA users in Taiwan. With a response rate of 82.4%, the final sample of 326 respondents (average age = 28.3; female = 54.9%) was analyzed by using two techniques of structural equation modeling (SEM) and cluster analysis.
Findings
The results indicate six antecedents of users’ continuance usage intention towards FDAs, including information quality, system quality, information quality, perceived usefulness, perceived enjoyment and satisfaction. Additionally, three distinct clusters of FDA users are successfully identified, labeled as “value sensitive users”, “time-sensitive users” and “security sensitive users”.
Originality/value
This study is one of the pioneers that explores the possible segments in FDA market, which helps FDA providers and food retailers develop more focused and appropriate strategies to encourage users to continue using FDAs. Our findings contribute to building an optimized version of “FDA Tech” that becomes an omni-channel solution to serve the increased home-delivery needs in the new normal era.

Abstract
Purpose
The purpose of this study is to examine the association between related party transactions (RPTs) in terms of sales and purchases and earnings management (EM).
Design/methodology/approach
The authors use the estimation method of system generalized method of moments (Sys-GMM) on a sample of 413 non-financial firms in Vietnam in the period from 2015 to 2019, totaling 1,638 firm-year observations. Multiple proxies for RPTs and EM are used to provide a comprehensive assessment of the relationship between the two factors.
Findings
There is a positive association between RPTs and EM, suggesting that both types of RPTs could reduce financial reporting quality and allow firms to be more engaged in earnings manipulation.
Originality/value
There are a number of studies investigating the above link, but they tend to use aggregate values (the sum of both sales and purchases with related parties) or just either accruals-based earnings or real EM. This study is the first to extend the literature on the relationship between RPTs and EM by examining both sales-based and purchases-based RPTs on both real and accruals-based earnings manipulation. This approach helps uncover the differences in the effect of the two types of RPTs on both types of upward EM.

Abstract
Purpose
This study aims to investigate the effect of spray drying temperature and maltodextrin addition on the contents of phenolics, flavonoids, anthocyanins and antioxidant activities (2,2-diphenyl-1-picrylhydrazyl [DPPH] radical scavenging activity, ferric reducing antioxidant power and reducing power) of karonda powder.
Design/methodology/approach
Over the past few decades, the demands for application of natural colorants in food production have been attracting the attention of academic research and food industry. Anthocyanins, a red pigment commonly found on plants, show high potentials in the preparation of spray-dried pigment powder. This study, therefore, was conducted using full factorial design with two factors, namely, inlet temperature (150°C and 160°C) and soluble solid concentration (10, 15 and 20°Brix) with maltodextrin as carrier to produce pigment powder from karonda, an anthocyanin-rich fruit which is native to southeast Asia.
Findings
Increasing soluble solid content from 10 to 15°Brix resulted in a 42%–57% reduction in phenolic, flavonoid and anthocyanin contents. However, when increasing the amount of maltodextrin from 15 to 20°Brix, a lower reduction (approximately 11%–19%) was observed. In samples with the same °Brix, there was no significant variation in antioxidant contents and activities, especially at high maltodextrin ratios. In addition, the reducing power of samples dried at higher temperature (160°C) was higher than that of samples dried at lower temperature. Karonda spray-dried powder showed a good positive correlation (p < 0.01) between antioxidant contents and DPPH• activity.
Originality/value
To the best of the authors’ knowledge, in this study, for the first time, the effect of spray drying conditions on the quality of karonda powder was investigated.
