Abstract
This article examines the impact of the ASEAN Free Trade Area (AFTA) on Korean exports to ASEAN countries by using the system generalized method of moments. The data covered 15 sectors according to their relative importance in Korean exports and spanned from 1980 to 2006. The estimated results suggest that Korea’s exports were diverted to ASEAN members as a result of the AFTA formation. In 5 of the 15 sectors, the AFTA exerted a significant negative effect on Korean exports to ASEAN countries, but for the remaining 9, the results were mixed and statistically insignificant. The results also indicate that the sectoral approach yields more robust and clear-cut results than the aggregate one.

Abstract
Purpose
This paper aims to examine the relationships between brand equity, customer satisfaction and cultural distance for a tourism destination. The mediating role of customer satisfaction and the moderating effect of cultural distance in these relationships are assessed.
Design/methodology/approach
The direct–indirect–moderating relationships were assessed by applying covariance-based SEM (CB-SEM), mediating and multi-group analysis. A paper survey was used to collect data from 618 tourists (domestic and international tourists) visiting a destination in Vietnam.
Findings
The findings support direct positive links between the dimensions of brand equity and customer satisfaction, except for the effect of destination brand awareness on destination brand loyalty. This work further demonstrates the mediating effect of customer satisfaction on the indirect relationships between the dimensions of brand equity. Cultural distance was found to moderate the connections between the research concepts.
Research limitations/implications
Future research should explore the model’s relationships based on comparisons in different destinations, to better understand the impact of cultural factors.
Originality/value
This study identifies specific factors to increase branding efficiency by developing and testing the relationship between brand equity and customer satisfaction. Using moderating variables through the lens of cultural distance, it proposes a mediated model. This work contributes to practice by informing destination managers on how to improve brand equity and satisfaction based on the cultural characteristics of international and domestic visitors.

Abstract
Purpose
Compliant mechanism has been receiving a great interest in precision engineering. However, analytical methods involving their behavior analysis is still a challenge because there are unclear kinematic behaviors. Especially, design optimization for compliant mechanisms becomes an important task when the problem is more and more complex. Therefore, the purpose of this study is to design a new hybrid computational method. The hybridized method is an integration of statistics, numerical method, computational intelligence and optimization.
Design/methodology/approach
A tensural bistable compliant mechanism is used to clarify the efficiency of the developed method. A pseudo model of the mechanism is designed and simulations are planned to retrieve the data sets. Main contributions of design variables are analyzed by analysis of variance to initialize several new populations. Next, objective functions are transformed into the desirability, which are inputs of the fuzzy inference system (FIS). The FIS modeling is aimed to initialize a single-combined objective function (SCOF). Subsequently, adaptive neuro-fuzzy inference system is developed to modeling a relation of the main geometrical parameters and the SCOF. Finally, the SCOF is maximized by lightning attachment procedure optimization algorithm to yield a global optimality.
Findings
The results prove that the present method is better than a combination of fuzzy logic and Taguchi. The present method is also superior to other algorithms by conducting non-parameter tests. The proposed computational method is a usefully systematic method that can be applied to compliant mechanisms with complex structures and multiple-constrained optimization problems.
Originality/value
The novelty of this work is to make a new approach by combining statistical techniques, numerical method, computational intelligence and metaheuristic algorithm. The feasibility of the method is capable of solving a multi-objective optimization problem for compliant mechanisms with nonlinear complexity.

This paper aims to design a PD controller for an active suspension system to improve the car’s moving smoothness.
Abstract
Purpose
This paper aims to design a PD controller for an active suspension system to improve the car’s moving smoothness.
Design/methodology/approach
The controller parameters are optimized by an in-loop genetic algorithm (iL-GA). Unlike previous studies that only used conventional GAs to tune coefficients for the controller, the iL-GA designed in this paper provides outstanding efficiency when determining the optimal value range for the system. The optimal value range of parameters is determined by the in-loop algorithm based on criteria related to systematic errors. The optimal values are then calculated by the GA based on this range instead of an uncertain one.
Findings
Simulation results show that vehicle body acceleration and displacement values are significantly reduced when using the active suspension system compared to the conventional passive suspension system. The phase difference phenomenon does not occur in the iL-GA situation. In addition, the frequency domain investigation also shows the system’s stability when using iL-GA instead of conventional GA.
Originality/value
To the best of the authors’ knowledge, this is a new application that provides positive effects to the suspension controller. This algorithm can be applied to tune coefficients for direct controllers in the future.

Abstract
Purpose
This paper aims to examine adaptive livelihood strategies used by small-scale fishing households in the two coastal communities in Central Vietnam under the context of climate change-related stressors.
Design/methodology/approach
Field data were collected through mixed quantitative and qualitative methods including a review of secondary data, key-informant interviews, group discussions and household surveys with 300 sampled fishing households. The qualitative data support the analysis and discussion of quantitative data.
Findings
The results showed local households’ perception of the presence and influence of multiple non-climate and climate stressors on their fishery-based livelihoods in terms of employment and income in many ways. The affected households exerted to develop a diversity of adaptation methods within and out of fishing to sustain their livelihoods and cover a deficit in household income. The household socio-demographic characteristics particularly education, labour force, fishing equipment and social support played significant importance in characterising the categories of adaptation strategies among the survey households. The role of local governments in creating an enabling environment for local-level adaptation, as well as protecting marine and coastal ecosystems was rather limited despite their recognized importance.
Originality/value
The paper provides an empirical case of how small-scale fishing households in coastal communities in Central Vietnam are adapting to climate-related stressors. It suggests policy should promote livelihood diversification opportunities and address household-level constraints for adaptation. Fisheries management plan is urgently needed to control illegal fishing activities for sustainable use of coastal and marine fishery resources and the appropriate mechanism is important to stretch local governments’ resources for better supporting local-level adaptation.

Abstract
Purpose
In the context of the contemporary globalized environment and the rapid progression of Industry 4.0, the existing literature suggests that national intellectual capital does play a significant role in shaping diverse economic metrics. However, the connection between national intellectual capital and total factor productivity (TFP) has been largely overlooked. This paper examines the effect of national intellectual capital on productivity across 84 countries, encompassing diverse income levels, human development index (HDI) levels and continents.
Design/methodology/approach
This study utilizes dynamic ordinary least squares (DOLS), fully modified ordinary least squares (FMOLS), two-stage least squares (2SLS), generalized method of moments (GMM) and pooled mean group (PMG) estimation techniques on a sample of 84 economies from 2000 to 2019.
Findings
The results reveal a significant effect of national intellectual capital on productivity. Countries with robust intellectual capital exhibit enhanced productivity and, by extension, sustainable economic growth. The findings are nuanced, illustrating varied impacts across low, middle and high-income countries and offering insights into tailored strategies for each income group. Nations with lower HDI levels derive significant benefits from investments in intellectual capital, whereas higher HDI countries experience lower returns in productivity gains from additional intellectual capital investments. Interestingly, Latin America exhibits a paradoxical negative effect of national intellectual capital on TFP.
Practical implications
This paper makes a significant contribution to the literature by extending the discourse on intellectual capital to the national level, an area that has been relatively underexplored. The comparative analysis across income groups, human development index levels and continents enriches the understanding of the multifaceted impacts of intellectual capital on productivity. These insights are valuable for policymakers, researchers and international development agencies, providing a comprehensive perspective on how intellectual capital influences productivity in diverse economic and developmental contexts.
Originality/value
To the best of our knowledge, this is the first empirical study to investigate the impact of national intellectual capital on productivity across 84 countries, considering diverse income levels, HDI levels and continents.

This study examines the influence of stock liquidity on stock price crash risk and the moderating role of institutional blockholders in Vietnam’s stock market.
Abstract
Purpose
This study examines the influence of stock liquidity on stock price crash risk and the moderating role of institutional blockholders in Vietnam’s stock market.
Design/methodology/approach
Crash risk is measured by the negative coefficient of skewness of firm-specific weekly returns (NCSKEW) and the down-to-up volatility of firm-specific weekly stock returns (DUVOL). Liquidity is measured by adjusted Amihud illiquidity. The two-stage least squares method is used to address endogeneity issues.
Findings
Using firm-level data from Vietnam, we find that crash risk increases with stock liquidity. The relationship is stronger in firms owned by institutional blockholders. Moreover, intensive selling by institutional blockholders in the future will positively moderate the relationship between liquidity and crash risk.
Practical implications
Since stock liquidity could exacerbate crash risk through institutional blockholder trading, firm managers should avoid bad news accumulation and practice timely information disclosures. Investors should be mindful of the risk associated with liquidity and blockholder trading.
Originality/value
We contribute to the literature by showing that the activities of blockholders could partly explain the relationship between liquidity and crash risk. High liquidity encourages blockholders to exit upon receiving private bad news.

Abstract
Purpose
This paper aims to examine the role of social media communication, tourist satisfaction and destination brand equity components in enhancing destination brand equity based on the Stimulus – Organism – Response (S-O-R) theory.
Design/methodology/approach
The conceptual model and research hypotheses were assessed using covariance-based structural equation modeling (SEM). An online survey was used to collect data from 369 domestic tourists who had traveled to Danang and knew about content related to Danang generated by either DMOs or other users on social media.
Findings
Except for the effect of DMO-generated social media communication on tourist satisfaction and the impact of destination brand awareness on destination brand loyalty, the findings confirmed the sequential causal relationships between research concepts based on the S-O-R model.
Research limitations/implications
Future research should explore the proposed model based on comparisons of different nationalities to better understand the impact of cultural factors.
Practical implications
DMOs should associate social media with their marketing strategies to enhance destination brand equity, using cutting-edge technologies to create content and update information in a significant way to make communications by DMOs more effective. The findings especially suggest that UGC plays a vital role in improving brand equity dimensions, so DMOs could exploit UGC to engage existing customers and build relationships with potential customers. This research provides guidance for DMOs to improve their brand equity based on social media.
Originality/value
This study has contributed to the destination marketing literature by applying the S-O-R theory to propose a pathway for effectively increasing destination brand equity and highlight the importance of social media communication as a driver to achieve a hierarchical relationship between destination brand equity components and tourist satisfaction from stimulus to organism (e.g. cognition to affect).

Abstract
Purpose
This study aims to examine the direct and indirect relationship between self-congruity and destination brand loyalty (DBL) based on the conceptual linkages of cognition, affect and conation. A multiple-step, multiple mediator model is investigated to explain the indirect effect of self-congruity on DBL through perceived destination quality (PDQ) and tourist satisfaction (TS). The moderating impact of visit frequency in these relationships is also proposed and empirically evaluated.
Design/methodology/approach
The conceptual model and research hypotheses were assessed by applying covariance-based structural equation modeling (SEM), mediating and multi-group analysis. An online survey was used to collect data from 347 domestic tourists visiting a destination in Vietnam.
Findings
The results support the link from self-congruity to PDQ, TS and then to DBL. Visit frequency was found to moderate the links between the research concepts.
Research limitations/implications
Future research would benefit from considering other self-congruity components (e.g. social self-congruity and ideal social self-congruity) and moderating variables (e.g. cultural distance). This would provide insights into the relationships between self-congruity and tourist behaviors and could be based on comparisons in different destinations to achieve more wide-ranging results.
Originality/value
The effect of self-congruity on DBL that evolves from linking self-congruity to PDQ and TS to increase DBL was examined within a tourism destination context. This study is valuable to destination managers as it provides suggestions to improve DBL.
