Abstract

Purpose

The purpose of this paper is to assess the impact level of six factors that condition participation in value chain of lychee growers in the Luc Ngan District of Bac Giang Province in Vietnam. This contributes to the literature on value chain development through the exploration of the case of an agriculturally based primary industry in the global south. Specifically, it analyzes the impacts of several factors on the participation of lychee fruit farmers in the attributed value chain of Bac Giang Province in the north of Vietnam to identify salient points of policy intervention.

Design/methodology/approach

Data for this study were collected from a survey of 270 lychee farmers in three districts of Bac Giang Province. Six factors, including the trust level of the participants, partner capacity, geographical distance between participants, collaborative culture, participation strategy and existence of specific government policies, were analyzed through a Kaiser–Meyer–Olkin (KMO) test, Cronbach’s alpha and the exploratory factor analysis (EFA) method to evaluate the reliability of the factors and suitability of the model. A regression analysis was then used to evaluate the impact level of each element on the collaboration of farmers in the chain.

Findings

The results show that each of the six factors has significant impacts on farmer participation and the resulting chain thickness. Although the findings of this study are drawn from the case of lychee farmers in the north of Vietnam, they are argued to be transferable to other countries with rapidly growing middle-income economies.

Research limitations/implications

The research conclusions are based on only the opinions of surveyed lychee growers in Luc Ngan District, Bac Giang Province. Similarly, this paper only explores six factors influencing participation in the value chain. Additional factors, including age, have not been used in this study and are suggested avenues for future research.

Originality/value

The paper suggests that policy makers on the local and regional levels in Vietnam reassess their focus and center these six factors as precursory conditions to improving local and regional economic development. Implications for other peripheral regions with agricultural production across the global south are also posited.

Abstract

Purpose

The purpose of this paper is to validate measures of professional self-efficacy for detecting and responding to child abuse and neglect presentations, and then evaluate a clinical training programme for health professionals in a tertiary-level hospital in Vietnam.

Design/methodology/approach

A prospective, cohort design was used and professional self-efficacy was measured immediately prior to, and shortly after, training 116 nurses and doctors in emergency settings. Longer-term follow-up was measured six months later.

Findings

Linear mixed modelling showed that there was a statistically significant improvement in efficacy expectations for both suspected and known cases of child abuse and neglect between the pre- and post-test measures at zero and six weeks. These improvements did not persist to the six-month follow-up.

Research limitations/implications

The training succeeded in improving detection and clinical response to child abuse and neglect presentations but not faith in the provision of ongoing support for children and families.

Practical implications

Practice change in emergency settings in Vietnam can be achieved using a sustainable theoretically driven training programme.

Social implications

Building the capacity of health professionals to respond to cases of child abuse and neglect relies on the strength of the community and support services within which the hospital is located.

Originality/value

Measures of self-efficacy expectations and outcome expectations for responding to child abuse and neglect presentations in emergency settings in Vietnam are now validated.

Abstract

Purpose

This study aims to solve problems of detecting copy-move images. With input images, the problem aims to: Confirm the original or forgery of the images, evaluate the performance of the detection and compare the proposed method’s effectiveness to the related ones.

Design/methodology/approach

This paper proposes an algorithm to identify copy-move images by matching the characteristics of objects in the same group. The method is carried out through two stages of grouping the objects and comparing objects’ features. The classification and clustering can improve processing time by skipping groups of only one object, and feature comparison on objects in the same group improves accuracy of the detection. YOLO5, the latest version of you only look once (YOLO) developed by Ultralytics LLC, and K-means are applied to classify and group the objects in the first stage. Then, modified Zernike moments (MZMs) and correlation coefficients are used for the features extraction and matching in the second stage. The Open Images V6 data set is used to train the YOLO5 model. The combination of YOLO5 and MZM makes the effectiveness of the proposed method for copy-move image detection with an average accuracy of 94.26% for images of benchmark and MICC-F600 and 95.37% for natural images. The outstanding feature of the method is that it can balance both processing time and accuracy in detecting duplicate regions on the image.

Findings

The problem is then solved by doing the following steps: Build a method to detect objects and compare their features to find the similarity if they are copy-move objects; use YOLO5 for the object detection and group the same category objects; ignore the group having only one object and extract the features of the other groups by MZMs; detect copy-move regions using K-means clustering; and calculate and compare the detection accuracy of the proposed method and related methods.

Originality/value

The main contributions of this paper include: Reduce the processing time by using YOLO5 in objects detection and K-means in clustering; improve the accuracy by using MZM to extract features and correlation coefficients to matching them; and implement and prove the effectiveness of the proposed method for three copy-move data sets: benchmark, MICC-F600 and author-built images.

Abstract

Purpose

This study aims to investigate the interrelationships between charter value and market discipline in five Southeast Asian countries (ASEAN-5).

Design/methodology/approach

This research uses a simultaneous equations model with a three-stage least squares estimator for a sample of 79 listed banks from 2006 to 2019.

Findings

The findings show a negative two-way relationship between charter value and market discipline. More specifically, charter value can reduce market discipline. Meanwhile, a negative relationship between market discipline and charter value reemphasizes the significance of market discipline in the banking system to enhance bank charter value. Similar results still hold when using several robustness checks (e.g. subsamples, considering the global financial crisis, governance indicators and market structure).

Originality/value

To the best of the authors’ knowledge, this study is the first attempt to investigate the bidirectional relationship between bank risk and charter value in ASEAN-5. Therefore, this study would provide significant recommendations for policymakers and practitioners.

Abstract

Purpose

The purpose of this study is to examine whether a bidirectional relationship between bank risk and market discipline may exist in Southeast Asia.

Design/methodology/approach

A simultaneous equations model with a three-stage least squares estimator is used to examine the interrelationships between bank risk and market discipline using a sample of 79 listed banks in five countries in Southeast Asia (ASEAN-5) from 2006 to 2019.

Findings

The findings show a two-way relationship between bank risk and market discipline. In particular, market discipline has a negative impact on bank risk, while there is a positive relationship between bank risk and market discipline. A bidirectional relationship between them still holds when using an alternative measure of bank risk in subsamples, controlling for the global financial crisis and governance indicators.

Practical implications

The findings indicate that market discipline can reduce bank risk. Meanwhile, a positive impact of bank risk on market discipline reemphasizes that market discipline is a powerful tool to ensure banks do not have excessive risk-taking. Nonetheless, the findings suggest that further implementation of market discipline as the third pillar of the Basel framework is necessary for the banking systems in ASEAN-5.

Originality/value

To the best of the authors’ knowledge, this study is the first attempt to investigate the interrelationship between bank risk and market discipline in Southeast Asia.

Abstract

Purpose

This study investigates the inter-relationships among liquidity creation, bank capital and credit risk in selected emerging economies between 2012 and 2016.

Design/methodology/approach

A three-step procedure as proposed by Berger and Bouwman (2009) is used to measure liquidity creation. Thereafter, a simultaneous equations model with the generalized method of moments (GMM) estimator is used to examine the links between liquidity creation, bank capital and credit risk.

Findings

The findings indicate that bank capital and credit risk affect each other positively after controlling for liquidity creation. Also, the findings show a negative impact of credit risk on liquidity creation while our findings do not find any evidence to confirm the reverse relationship between them. Furthermore, the findings demonstrate a two-way negative relationship between liquidity creation and bank capital in these emerging economies. Finally, the results indicate a positive relationship between capital and credit risk, especially in the case of small banks in the sample.

Practical implications

The findings suggest that the trade-off between the benefits of financial stability induced by tightening capital requirements and those of improved liquidity creation has crucial implications for policymakers and bank regulators in making the banking system more resilient. A positive impact of capital on credit risk emphasizes that the authorities in selected emerging economies should put more attention on small banks to ensure their exposures under target control.

Originality/value

This is the first study that examines the dynamic interrelationships among liquidity creation, bank capital and credit risk in the Asia–Pacific region.

Abstract

Purpose

This study aims to investigate whether the changes in gender composition of bank board affects Vietnamese bank stability efficiency.

Design/methodology/approach

This research covers a panel of 27 commercial banks in Vietnam over a 14-year period from 2007 to 2020. The two-step system generalized method of moments is used to estimate the gender diversity–Vietnamese bank stability efficiency nexus.

Findings

The authors find that a greater degree of board gender diversification enhances bank stability efficiency and reduces bank risk-taking in Vietnam. The relationship between gender diversity and the stability efficiency of Vietnamese banks is still valid under the influence of regulatory capital sufficiency and during the financial crisis. These findings are robust to alternative proxies for risk indicators and consistent with the perspectives of stakeholder and behavior theory.

Originality/value

Although this research revisits the relationship between gender diversity and bank risk-taking, it is the first attempt to explore the role of women on board in enhancing the stability efficiency of banks, using the stochastic frontier approach. These findings shed light on the function of gender diversity as a governance instrument for mitigating risk in an emerging market context.

Abstract

Purpose

This study investigated the impacts of the environment, social and governance (ESG) and its components on global bank profitability considering the COVID-19 outbreak.

Design/methodology/approach

This study used a system generalized method of moments (GMM) proposed by Arellano and Bover (1995) to investigate the relationship between ESG and bank profitability using an unbalanced sample of 487 banks from 51 countries from 2006 to 2021.

Findings

The findings generally found that ESG activities may reduce bank profitability, thus supporting the trade-off hypothesis that adopting ESG standards could increase bank costs while lowering profitability. In addition, there is a U-shaped relationship between ESG and bank profitability, suggesting that ESG activities can help improve bank performance in the long term. Such an effect is the first time observed in the global banking sector. This study’s results are robust across different models and settings (e.g., developed vs. developing countries, different levels of profitability, and samples with vs without US banks).

Practical implications

This study provides empirical evidence to support many countries' sustainable development policies. It also provides empirical incentives for bank managers to be more ESG-oriented.

Originality/value

This study provides a better understanding of the roles of ESG activity and its components in the global banking system, considering the recent crises.

Abstract

Purpose

This study explored students' perspectives on designing and implementing the new clinical interprofessional education (IPE) module for chronic disease management at the primary care level in the Vietnamese context.

Design/methodology/approach

Students from seven different university-level healthcare programmes participated in a cross-sectional survey Course Experience Questionnaire-based study. Additionally, two open-ended questions were presented to gather qualitative data, mapping student perspectives. Statistical analyses and thematic analyses were performed.

Findings

The results show that students agree with quality statements about IPE design features, such as good teaching, clear goals and standards, appropriate workload, appropriate assessment and a blended learning approach. Answers to the open-ended comments pointed out the strengths of the IPE module in providing opportunities for interprofessional learning, improving interprofessional collaboration competencies, real-life interprofessional collaboration practice and continuous feedback from tutors. Students also reported weaknesses in the IPE module, including a lack of feedback on the care plan and logistics of the IPE module.

Originality/value

Students positively recognise key design features of the IPE module, combining classroom activities with standardised patient simulations, clinical practice and home visits. Chronic disease management at the primary care level is a suitable context for training students to work interprofessionally. The strengths and weaknesses identified by students could help in the redesign and future implementation of the IPE module in the Vietnamese context. They could inspire practices in Southeast Asian medical education and beyond.

Abstract

Purpose

The study aims to investigate the relationship between a shift in lending activities toward households, credit information sharing and bank stability.

Design/methodology/approach

A system generalized method of moments (GMMs) as proposed by Arellano and Bover (1995) is employed to examine the relationship using a sample of 80 countries from 2005 to 2014.

Findings

The findings demonstrate that, in general, a shift in lending strategy toward the household sector may increase bank instability while credit information sharing has a positive impact on bank stability. When credit information sharing is promoted widely, this shift may become beneficial for the banking system. The results are robust when using different measures of credit information sharing, including the depth of index and the coverage of credit information sharing mechanisms.

Practical implications

The results demonstrate that a shift in lending activities toward households should be considered a key variable in conducting macro-prudential policies. When a shift toward household credit relative to firm credit is evolved, the findings suggest that the authorities around the world should enact laws that magnify the scope and coverage of credit information shared and thus promoting the effectiveness of information sharing.

Originality/value

The current study is the first attempt that examines the impacts of a shift in lending activities toward households and credit information sharing on bank stability.
