Abstract
Purpose
A popular production model for high-tech manufacturers is that they move most production lines abroad to produce formal products for sale and just keep a few production lines in headquarters to manufacture sample products for new product development. Under such a production model, the paper aims to develop a selection model of International Air Express (IAE) for high-tech manufacturers in airfreight of sample products using the fuzzy best-worst method (BWM).
Design/methodology/approach
In this paper, an assessment model based on the fuzzy BWM approach is proposed for high-tech manufacturers in selecting airfreight carriers for the shipping of sample products. Further, one high-tech electronic manufacturer in Taiwan was empirically investigated to validate the assessment model.
Findings
The result indicates that electronics manufacturer pays more attention to Promptness, Mutual trust, Freight rate and Financial status of fixed assets when selecting IAEs. Besides, FedEx is argued to be the most preferred IAE for the transportation of sample products. Based on the findings, some practical management implications were discussed.
Research limitations/implications
Some literature limitations should be addressed. Initially, the adoption of the fuzzy BWM assumes independence among criteria. Nonetheless, this assumption is not yet to confirm in this study. Accordingly, this limitation leaves room for improvement in future studies. Further, in this paper, five experienced experts from the Radiant Opto-Electronics Corporation (ROEC) case were empirically surveyed. To ensure the validity of the surveying, this paper adopted an interviewing survey instead of a traditional mailed survey. However, more representative samples are still necessary to confirm the empirical results in future research.
Practical implications
Firstly, the proposed research model provides a systematic framework to the decision-making process, which assists high-tech manufacturers in identifying the most suitable IAEs based on multiple criteria. It has been illustrated that high-tech companies deliver their sample products requiring timely and secure means of transport. In practice, manufacturers can assess various IAEs considering some main factors, such as Operational Flexibility (OF), Partner Relationship (PR), Transportation Capability (TC) and Management, using fuzzy BWM. This process ensures the selection of IAEs aligning with their logistical needs and business priorities, ultimately enhancing operational efficiency and customer satisfaction. Secondly, empirical results from the ROEC case indicate that electronics manufacturer pays more attention to Promptness, Mutual trust, Freight rate and Financial status of fixed assets when selecting IAEs. Besides, FedEx is argued to be the most preferred IAE for transportation of sample products. In other words, ROEC should consider establishing long-term contracts with preferred IAEs (i.e. FedEx) to secure favorable rates and service commitments. On top of that, results not only provide practical information for manufacturers in selecting IAEs but also for IAE partners to improve their service policies.
Originality/value
The results not only provide practical information for high-tech manufacturers in selecting airfreight carriers but also for the airfreight carriers to improve their service quality.

Abstract
Purpose
The consolidation behavior of prefabricated vertical drain (PVD)-installed soft deposits mainly depends on the PVD performance. The purpose of this study is to propose a numerical solution for the consolidation of PVD-installed soft soil using the large-strain theory, in which the reduction of discharge capacity of PVD according to depth and time is simultaneously considered.
Design/methodology/approach
The proposed solution also takes into account the general constitute relationship of soft soil. Subsequently, the proposed solution is applied to analyze and compare with the monitoring data of two cases, one is the experimental test and another is the test embankment in Saga airport.
Findings
The results show that the reduction of PVD discharge capacity according to depth and time increased the duration required to achieve a certain degree of consolidation. The consolidation rate is more sensitive to the reduction of PVD discharge capacity according to time than that according to the depth. The effects of the reduction of PVD discharge capacity according to depth are more evident when PVD discharge capacity decreases. The predicted results using the proposed numerical solution were validated well with the monitoring data for both cases in verification.
Research limitations/implications
In this study, the variation of PVD discharge capacity is only considered in one-dimensional consolidation. However, it is challenging to implement a general expression for discharge capacity variation according to time in the two-dimensional numerical solution (two-dimensional plane strain model). This is the motivation for further study.
Practical implications
A geotechnical engineer could use the proposed numerical solution to predict the consolidation behavior of the drainage-improved soft deposit considering the PVD discharge capacity variation.
Originality/value
The large-strain consolidation of PVD-installed soft deposits could be predicted well by using the proposed numerical solution considering the PVD discharge capacity variations according to depth and time.

Purpose
This paper aims to present a hybrid review combining the theory, context, characteristics and methodology (TCCM) framework and bibliometric analysis of international business research from 1991 to 2023, shedding light on the field’s growth, trends and key contributors.
Design/methodology/approach
Relevant papers were selected using the preferred reporting items for systematic reviews and meta-analyses model. Initially, this paper conducted a descriptive analysis to identify prolific institutions, countries and journals. Using bibliometric techniques and the TCCM framework, this paper analyzed theory, context and method visualized through word clouds and keyword co-occurrence. The characteristic aspect was analyzed using bibliographic coupling to identify major themes, providing a comprehensive understanding of the most significant factors in international business research.
Findings
The analysis of a data set comprising 5,644 documents reveals a steady increase in the annual growth rate of publications, highlighting the growing significance of international business in the global economy. First, this paper noticed a significant increase in publications in leading international business journals, with the Journal of International Business Studies being the most prolific. Second, using the TCCM framework, this paper discovered that the resource-based view, institutional theory, transaction cost theory and internalization theory are predominant in international business research. Most studies have concentrated on firm or enterprise-level entities, followed by country-level analyses. This paper also identified six main themes: (1) innovation and strategy, (2) market, (3) HR impact and leadership, (4) marketing, (5) internationalization and (6) entrepreneurship. Quantitative methods have been the most frequently used research design, followed by qualitative and mixed methods.
Research limitations/implications
The study offers researchers and practitioners a roadmap for future investigations, collaboration and innovation in international business, thereby advancing the knowledge and understanding of this complex field within a globally interconnected economy.
Originality/value
This study provides insights into growth and trends, identifying journals, clustering research topics and enhancing theoretical and methodological understanding in the field of international business.

Abstract
Purpose
In the COVID-19 outbreak periods, people's life has been deranged, leading to disrupt the world. Firstly, the number of deaths is growing and has the potential to surpass the highest level at any time. Secondly, the pandemic broke many countries' fortified lines of epidemic prevention and gave people a more honest view of its seriousness. Finally, the pandemic has an impact on life, and the economy led to a shortage in medical, including a lack of clinicians, facilities and medical equipment. One of those, a simple ventilator is a necessary piece of medical equipment since it might be useful for a COVID-19 patient's treatment. In some cases, the COVID-19 patients require to be treated by modern ventilators to reduce lung damage. Therefore, the addition of simple ventilators is a necessity to relieve high work pressure on medical bureaucracies. Some low-income countries aim to build a simple ventilator for primary care and palliative care using locally accessible and low-cost components. One of the simple principles for producing airflow is to squeeze an artificial manual breathing unit (AMBU) iterative with grippers, which imitates the motion of human fingers. Unfortunately, the squeezing angle of grippers is not proportional to the exhaust air volume from the AMBU bag. This paper aims to model the AMBU bag by a mathematical equation that enables to implement on a simple controller to operate a bag-valve-mask (BVM) ventilator with high accuracy performance.
Design/methodology/approach
This paper provides a curvature function to estimate the air volume exhausting from the AMBU bag. Since the determination of the curvature function is sophisticated, the coefficients of the curvature function are approximated by a quadratic function through the experimental identification method. To obtain the high accuracy performance, a linear regression model and a least square method are employed to investigate the characteristic of the BVM ventilator's grippers angle with respect to the airflow volume produced by the AMBU bag.
Findings
This paper investigates the correlation between the exhausting airflow of the AMBU bag and the grippers angle of the BVM ventilator.
Originality/value
The experimental results validated that the regression model of the characteristic of the exhausting airflow of the AMBU bag with respect to the grippers' angle has been fitted with a coefficient over 98% within the range of 350–750 ml.

Abstract
Purpose
This study explores the economic impact of the COVID-19 crisis on herding behaviour in the Australian equity market by considering liquidity, government interventions and sentiment contagion.
Design/methodology/approach
This study utilizes a daily dataset of the top 500 stocks in the Australian market from January 2009 to December 2021. Both predictive regression and portfolio approaches are employed to consider the impact of COVID-19 on herding intention.
Findings
This study confirms that herding propensity is more pronounced at the beginning of the crisis and becomes less significant towards later phases when reverse herding is more visible. Investors herd more toward sectors with less available information on financial support from the government during the financial meltdown. Conditioning the stock liquidity, herding is only detectable during highly liquid periods and high-liquid stocks, which is more observable during the initial phases of the crisis. Further, the mood contagion from the United States (US) market to Australian market and asymmetric herding intention are evident during the pandemic.
Originality/value
This is the first study to shed further light on the impact of a health crisis on the trading behaviour of Australian investors, which is driven by liquidity, public information and sentiment. Notwithstanding the theoretical contributions to the prior literature, several practical implications are proposed for businesses, policymakers and investors during uncertainty periods.

Abstract
Purpose
This article analyzes the impact of social insurance on firm performance by obtaining evidence from Vietnamese small- and medium-sized enterprises.
Design/methodology/approach
The method employed in the research is the generalized method of moments for testing hypotheses of data collected from the General Statistics Office of Vietnam.
Findings
The results show that social insurance contributions can enhance firm performance in three dimensions: return on equity (ROE), labor productivity and total factor productivity (TFP). In addition, financial leverage, firm size, the average wage of workers and fixed assets have an impact on the social insurance costs of these companies.
Originality/value
This article provides a novel explanation of the contribution of social insurance to firm performance. In particular, social insurance contribution not only increases labor productivity but also boosts the growth of the TFP of companies. In addition, the article points out that taking care of the benefits of employees is a valuable investment of companies. These are the unique contributions of the paper to the literature on the economic impact of social insurance.

Abstract
Purpose
The transition from fossil fuel-based energy systems to renewable energy sources, commonly referred to as the energy transition, is essential for combating climate change. However, comprehensive studies that thoroughly examine the financial mechanisms involved in this process are lacking. Despite the availability of various financial tools, there is a notable absence of extensive research that synthesizes and categorizes these mechanisms into broad groups.
Design/methodology/approach
A systematic literature review is used to explore a comprehensive framework for financial mechanisms related to the energy transition and their application across six stages of the process.
Findings
The framework of financial mechanisms for energy transition encompasses these six factors: public financing mechanisms, private financing mechanisms, market-based mechanisms, innovative financing mechanisms, risk mitigation instruments and institutional support and capacity building.
Originality/value
This is the first study that thoroughly reviewed the financial mechanisms involved in the energy transition process.
