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.

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.

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.

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.

This study aims to develop a comprehensive understanding about employer branding dimensions as well as the dimension's possible links with turnover intentions through the lens of existing hospitality employees.

A survey was conducted based on a sample of 200 hospitality employees in order to examine relationships between employer branding dimensions and turnover intentions. Structural equation modeling (SEM) was used for data analysis and hypothesis testing.

The findings found that economic, social, development and security values had negative impacts on turnover intentions; however, the impact of application and interest values on turnover intentions were not confirmed.

Hospitality managers can prioritize actions and strategies that influence their staff's intentions to quit, subsequently reducing employee turnover.

Given the lack of studies on employer branding dimensions from the perspective of current employees, especially the employees’ relationships with employee turnover intentions, this study points out employer branding factors that impact employee turnover intentions in the settings of coronavirus disease 2019 (COVID-19). The findings add to the literature on employer branding and employee turnover management and provide insights for hospitality managers in the context of the New Normal.

The aim of this empirical study is to investigate an integrated model that captures the way service quality of banking kiosks (BK-SQ) exerts its impacts on customer perceived value and customer satisfaction and the moderating mechanism of technology readiness (TR) in the quality–satisfaction relationship in the banking sector in Vietnam.

An offline survey was conducted to obtain responses from 604 users of banking kiosks in Vietnam. Exploratory factor analysis, confirmatory factor analysis and structural equation modeling were used for data analysis. The moderating effect of TR was examined following the product indicator method.

The results validate significant positive correlations between BK-SQ, customer perceived value and customer satisfaction. Among six service quality dimensions, convenience is the most significant factor in predicting perceived service quality. The study also delineates how TR can moderate the link between service quality and customer satisfaction.

Future studies may make further attempts to incorporate other human and demographic factors as a moderator into the research model.

Bank managers should strive to improve the operations of banking kiosks based on six aspects and increase TR levels of customers to boost customer satisfaction with banking kiosks.

The study contributes to the literature on service quality and self-service technologies (SSTs) by offering critical insights into how banks can make use of influence mechanisms in the model to enhance service quality and customer satisfaction.

This study aims to explore the pathway of increasing hotel booking intentions by mapping the linkage mechanism between the antecedents and components of brand equity to ultimately drive followers’ hotel booking intention. In addition, the role of over-endorsement as a moderating variable is also evaluated.

The conceptual model and research hypotheses were each assessed using covariance-based structural equation modeling. Paper-based and online surveys were used to collect data from 443 respondents who are TikTok users and follow at least one TikTok online celebrity, while that online celebrity must have reviewed at least one type of accommodation.

Except for the relationship between virtual interactivity and online celebrity brand image, the results confirmed the relationships between research concepts.

Further studies are needed to validate the results in other cultural contexts, generalize findings and broaden the range of target respondents.

This study contributes to the hotel literature by illustrating how online celebrity brand equity (OCBE) drives hotel booking intentions. The study highlights the importance of antecedent factors – follower-centered drivers (e.g. lifestyle congruence, friendship) and online celebrity-led drivers (e.g. virtual interactivity, expertise) – to achieve a hierarchical relationship between OCBE components and followers’ booking intentions.

This study aims to investigate the impact of several factors on customer satisfaction and intention of reusing ride-hailing services that is a new type of passenger urban transport service.

This research applied the Partial Least Squares Structural Equation Modeling analysis method to examine the measurement scale and to analyze the primary data collected from 388 passengers in Vietnam.

This study demonstrates that three dimensions of perceived value, namely, functional value, hedonic value and economic value, positively influence customer satisfaction. The other dimension of perceived value, which is social value, has an ambiguous effect on satisfaction. In addition, personal innovativeness promotes all dimensions of perceived value. In particular, this study highlights that customer satisfaction and corporate image positively impact reuse intention, and corporate image moderates the relationship between customer satisfaction and reuse intention.

This study enriches knowledge about customer behavior using services based on the sharing economy business model. In particular, theoretical and practical implications are provided for researchers and enterprises to find suitable strategies for business.

This study addresses the empirical results of the spillover effect with export as the primary economic activity that enhances local businesses' total factor productivity (TFP). A learning mechanism is expected to be generated and used as the basis for the policy implication.

This study adopted the Cobb–Douglas function and multiple estimation approaches, including the generalized method of moments, the Olley–Pakes and the Levinsohn–Petrin estimation techniques. The findings were estimated based on the panel data of a Vietnamese local businesses survey conducted by the General Statistics Office of Vietnam (GSO) from 2010 to 2019.

The results showed that the highest TFP belongs to the businesses in the Southeast region, the Mekong Delta region, the mining industry and the foreign-invested enterprises. The lowest impacted TFP are businesses in the Northwest region and agricultural, forestry and fishery sectors. In addition, the estimated results also show that the positive spillover effect on TFP is shown through forward and backward linkage. The negative spillover effect is expressed through the backward and horizontal channels.

This study offers original empirical evidence on the learning mechanisms via which exports contribute to productivity improvement in a developing Asian economy, so making a valuable contribution to the existing academic literature in this domain. The findings of this research make a valuable contribution to the advancement of understanding on the many ways via which spillover effects manifest such as horizontal, forward, backward and supplied-backward linkage.

The study's findings indicate that it is advisable for governments to give priority to the development and improvement of forward and supply chain linkages between exporters and local suppliers. This approach is recommended in order to optimize the advantages derived from export spillovers. At the organizational level, it is imperative for enterprises to strengthen their technological and managerial skills in order to efficiently incorporate knowledge spillovers that originate from overseas partners and trade counterparts.

This study sheds new evidence on the export spillover effect on productivity in emerging economies, with Vietnam as the case study. The paper contributes to the research's originality by adopting novel methodological aspects to estimate local businesses' impact on total factor productivity.

The purpose of this paper is to adopt the theory of planned behavior to close the entrepreneurial attitude–intention–behavior gap in the entrepreneurship field as well as test the key moderators of the entrepreneurial process, starting from entrepreneurial attitude and intention to behavior to engage in entrepreneurial activities – namely, entrepreneurship education.

The research used a sample of 2,566 students from 16 universities in Vietnam. First, Cronbach’s alpha and confirmatory factor analysis have been used to test the reliability and validity of scales. Then the coefficient paths in the conceptual framework were tested through structural equation modeling, and indirect associations were estimated via the PROCESS bootstrapping approach.

The research illustrated that both attitudes toward entrepreneurship and entrepreneurial intention serve as the central antecedents in the formation of entrepreneurial behavior. Also, when students are more entrepreneurially educated, the linkage between attitude toward entrepreneurship and entrepreneurial behavior was hypothesized to become stronger, yet the relation between entrepreneurial intention and behavior was weakened.

This research suggests useful recommendations for educators and policymakers to encourage university students’ favorable attitudes toward entrepreneurial activities, their intention to engage in them and their subsequent entrepreneurial behavior.

This research is expected to make a significant contribution to the entrepreneurship literature by closing the entrepreneurial attitude–intention–behavior gap as well as enriching our understanding of the influence of entrepreneurship education on the entrepreneurial process. Importantly, this research reveals that entrepreneurial education significantly moderates the effects of attitude toward entrepreneurship and entrepreneurial intention on entrepreneurial behavior.

From a consumer–brand relationship (CBR) perspective, this study proposes a serial multiple mediation model to explore the pathways (e.g. cognitive, affective and hybrid) to increase online celebrity brand equity (OCBE) and follower's hotel booking intentions (FBI).

Paper-based and online surveys were used to collect data from 443 respondents who had been using TikTok and had followed at least one online celebrity on TikTok, while that online celebrity had reviewed one or more types of accommodation. A serial multiple mediation model was evaluated through covariance-based structural equation modeling.

The results confirmed the hybrid cognitive–affective and cognitive–affective–conative pathways among antecedents and components of OCBE and FBI.

From a CBR perspective, this study provides a serial multiple mediation model to increase OCBE via hybrid cognitive–affective pathways and to drive FBI via cognitive–affective–conative pathways. These sequential relationships contribute to the human branding literature by defining a mechanism of how online celebrities can efficiently attract followers, thus driving online celebrity brand loyalty and hotel booking intentions.

The results should be validated in other cultural contexts to generalize findings and broaden the range of target respondents to include international followers and those within other nations.

In recent years, climate for innovation has attracted wide attention from industry and academia. It is perceived as a critical component of innovation performance in the built environment sector, especially in architectural design firms (ADFs). This study attempts to assess the degree of climate for innovation in the Vietnamese ADFs under the organizational climate theory.

A list of 13 innovation climate variables was found by reviewing previous studies and discussions with industry practitioners. These variables were then categorized into three principal factors (personal commitment, tolerance of difference, and support for creativity), forming the inputs of the fuzzy synthetic evaluation (FSE) analysis.

The results showed that the overall level of innovation in the climate is moderate, implying that it is still necessary for more improvements to the Vietnamese ADFs. The fuzzy analysis revealed that support for creativity was the most critical factor, followed by tolerance of difference and personal commitment.

The proposed climate for innovation model is practical and reliable for architectural professionals and can be applied to assess other research areas. Few studies have emphasized the innovation climate in the construction sector, so this research may broaden the knowledge and literature on the industry, especially for the ADFs.

This paper investigates the key determinants affecting household spending for university degree in Vietnam. This paper serves as empirical evidence for policymakers to select appropriate factors to estimate financial needs for university students in Vietnam.

We employ an innovative variable selection approach with adaptive LASSO for Tobit Regression Model.

The results suggest income, region and ethnicity play significant roles in determining higher education expenditure at Vietnamese households. Gender-related indicators (such as gender of household head, student’s gender), distance to school, occupations, etc. are empirically insignificant.

This study proposes a data-driven method by interfering regulation and Tobit regression to understand the divergence in higher education spending. Especially, adaptive LASSO was first introduced to identify key determinants of higher education expenditure at household level in Vietnam. It hopes to tackle over-fitting problems of traditional OLS regression in previous literature.
