Abstract

Purpose

This paper aims to explore how research and development (R&D) scientists and engineers can contribute to sustainability initiatives in their organisations.

Design/methodology/approach

This paper uses a critical case study methodology, focussed on a large Vietnamese company in which business leaders sought to engage R&D scientists and engineers in sustainability initiatives focussed on eco-innovation and eco-efficiency. Bourdieu’s theoretical lens of habitus, capitals and field facilitates a relational analysis of the findings.

Findings

While R&D scientists and engineers adapted well to early changes aligned with eco-innovation, they struggled to engage with sustainability initiatives in the case firm. This study explains adaptions and constraints as scientists and engineers’ professional habitus and capitals, and their broader organisational field.

Practical implications

This paper provides insight into how organisations might integrate professional acculturation and appropriate facilitators to promote the additional contribution of scientists and engineers to sustainability initiatives in the context of an organisation.

Social implications

Although eco-innovation and eco-efficiency are only potential dimensions of comprehensive organisational sustainability reform, this research provides insight into how engaging scientists and engineers with a broader social sustainability agenda might be advanced.

Originality/value

The study addresses calls for empirical insights into ways that scientists and engineers can commit to organisational sustainability practices based on the configurations of habitus, capital and organisational field.

Abstract

Purpose

This study explores the effects of gender and participation in agricultural cooperatives on biodiversity conservation farming practices in vegetable production.

Design/methodology/approach

This study used data collected from a survey of 627 vegetable farmers in Viet Nam and employed the Ordered Probit regression model to examine the effects of gender and participation in agricultural cooperatives on biodiversity conservation farming practices.

Findings

We find that female vegetable farmers are more likely to conduct biodiversity conservation farming practices than male farmers. This gender difference is, however, removed when participation in agricultural cooperatives is controlled, suggesting that agricultural cooperatives effectively facilitate biodiversity conservation farming practices.

Research limitations/implications

It is noted that our study is not free from some limitations. First, we conducted our study on vegetable farmers only. The biodiversity conservation practices in vegetable cultivation might be different from other types of farming. Future studies should be conducted with other types of agricultural cultivation. Second, we do not have enough data to explain why female farmers are more likely to adopt biodiversity conservation practices than male farmers. Future studies should capture biological and social aspects of gender differences to address this limitation.

Originality/value

This study contributes to the literature on biodiversity conservation by presenting empirical evidence on the effects of gender and agricultural cooperatives. Participation in agricultural cooperatives is revealed to facilitate the adoption of biodiversity conservation practices. In addition, we find that the education of farmers, the number of years that farmers have been living in the local area and the quality of land and water are positively related to the adoption of biodiversity conservation practices in vegetable production.

Abstract

Purpose

This study aims to spot wheat data and disaggregated commitment of trader data for CME traded wheat futures to examine the effect of exogenous shocks for hedging positions of Producers and Swap Dealers on cash-futures basis and excess futures returns.

Design/methodology/approach

A Bayesian vector autoregression (BVAR) methodology is used to capture volatility transfer effects.

Findings

Evidence is presented that institutional short hedging positions play a major role in the pricing of asymmetric information held by Swap Dealers into the basis. The results also indicate that producer hedging contains information when conditions in the supply chain create a shift in long vs short hedging demand. Finally, the results demonstrate that that Swap Dealer short hedging has the greatest effect on risk premium size and historical volatility.

Originality/value

Various proxies for spot prices are used in the literature, although actual spot price data is not common. In addition, stationarity for basis and open interest data is induced using the Baxter-King filter which allows us to work with levels, rather than percentage changes, in the time series data. This provides the ability to directly observe the effect of outright open interest positions for hedgers on contemporaneous innovations in basis and in excess returns. The use of a BVAR methodology represents an improvement over other structural VAR models by capturing contemporaneous systemic effects within an endogeneity based structural framework.

Abstract

Purpose

The purpose of this study is to develop a theoretical model for consumer behavioral intention by integrating the technology acceptance model (TAM) and the theory of perceived risk, which is tested on the intended use of credit cards in Vietnam.

Design/methodology/approach

The data were collected from 485 bank customers through a nationwide online survey. An exploratory and confirmatory factor analyzes were performed to validate the factor structure of the measurement items while structural equation modeling was used to validate the proposed model and testing the hypotheses.

Findings

The results of structural equation modeling reveal that perceived risk, perceived usefulness, social influence and perceived ease of use were significant determinants of consumer intention to use a credit card. Of them, only perceived risk discouraged the intended use of a credit card, which was synthesized from psychological, financial, performance, privacy, time, social and security risk.

Research limitations/implications

This study measured the first-order risk dimensions based on the payment function of the credit card only; these measurements missed potential losses relevant to credit function of credit cards.

Practical implications

This study can be beneficial to banks enacting policies to attract more consumers and to help decide how to allocate resources to retain and expand their customer base.

Originality/value

The study adds value to the literature on consumer behavior by confirming the impact of second-order perceived risk on the intended use of credit cards, which most previous studies have not demonstrated. The research also provides an empirical evidence to the academic research platform on e-banking services in Vietnam, especially related to the credit card industry.

Abstract

Purpose

The purpose of this paper is to propose an approach, which is easy to implement, for estimating the thickness of the air layer that may separate metallic parts in some aeronautical assemblies, by using the eddy current method.

Design/methodology/approach

Based on an experimental study of the coupling of a magnetic cup core coil sensor with a metallic layered structure (consisting of first metal layer/air layer/second metal layer), which is confirmed by finite element modelling simulations, an inversion technique relying on a polynomial forward model of the coupling is proposed to estimate the air layer thickness. The least squares and the nonnegative least squares algorithms are applied and analysed to obtain the estimation results.

Findings

The choice of an appropriate inversion technique to optimize the estimation results is dependent on the signal-to-noise ratio of measured data. The obtained estimation error is smaller than a few percent, for both simulated and experimental data. The proposed approach can be used to estimate both the air layer thickness and the second metal layer thickness simultaneously/separately.

Originality/value

This model-based approach is easy to implement and available to all types of eddy current sensors.

Abstract

Purpose

This study aims to evaluate the impact of green human resource management on cognitive factors, employees' pro-environmental behavior and the environmental performance of hotels in Vietnam.

Design/methodology/approach

Drawing upon primary data collected from a sample of 393 hotel employees, this study utilizes covariance-based structural equation modeling (CB-SEM) to test hypotheses and conduct path analysis.

Findings

The study’s findings reveal several key insights. Firstly, GHRM positively influences environmental knowledge (EK), environmental attitude (EA), attitude toward pro-environmental behavior (APB), pro-environmental behavior (PB) of employees and environmental performance (EP) of hotels. Additionally, the results also indicate that EK promotes EA, APB and PB, and both EA and EK can predict PB of employees. Surprisingly, the results from CB-SEM analysis reject the direct impact of APB on PB. Moreover, this study also confirmed the positive influence of PB on EP of hotels. Notably, the research delves into the moderating effect of work overload (WO) on the associations between GHRM and PB, as well as APB and PB.

Practical implications

The findings offer valuable recommendations for hotel managers and policymakers, aiming for effective GHRM practices and improvement of employees’ PB and EP of hotels.

Originality/value

This study broadens the understanding of sustainable management practices, specifically in human resource management in the hospitality industry. Notably, it identifies significant avenues to address theoretical gaps left by previous studies.

Abstract

Purpose

The purpose of this study is to examine the relationships between chief executive officers (CEOs) with military service and firm dividend and cash holding decisions.

Design/methodology/approach

The authors use a sample of Standard and Poor's (S&P) 1500 firms in the USA over a sample period from 1999 to 2017 and a panel data approach, as well as instrumental variable (IV)analysis. The models control for firm characteristics as well as industry and year-fixed effects.

Findings

The results show CEOs with military service are associated with higher total payout and less cash. Higher dividends appear to drive the total payout result. When cash holdings are split into pure cash and short-term investments, the reduction in cash holdings is driven by a reduction in pure cash. The findings are more pronounced for powerful CEOs and CEOs with low labor mobility. Military CEOs are also associated with less risk, measured by stock return volatility and return on assets (ROA) volatility.

Originality/value

Overall, the results are consistent with military CEOs implementing conservative policies that reduce firm risk, curtailing the demand for precautionary cash and reducing the necessity to forego dividend payouts.

Abstract

Purpose

This study aims to examine the relationship between corporate environmental responsibility (CER) practices and different types of innovation carried out by small- and medium-sized enterprises (SMEs) in Vietnam.

Design/methodology/approach

The authors employ the bivariate probit model and the two-stage least squares regression model to estimate the effects of CER on process innovation and product innovation of SMEs.

Findings

The findings show that while CER is not significantly related to product innovation, it has a positive and significant effect on process innovation. Further analysis indicates that CER engagement increases labor productivity and financial performance of SMEs.

Practical implications

Corporate managers should view implementation of environmental responsibility practices as a strategy to foster process innovation and boost labor productivity and financial performance. For policy makers, government support for firms proactively engaging in CER practices could encourage firms to pursue innovative activities, which are vital to their long-term success as well as to the society's prosperity.

Originality/value

This study makes several important contributions. First, the authors provide new empirical evidence regarding the different effects of engaging in environmentally friendly practices on firm innovation in an under-examined emerging market setting. Second, the authors enrich our understanding of potential benefits of CER implementation. Third, the findings suggest that firm innovation may play a mediating role in the CER–firm performance association.

Abstract

Purpose

The purpose of this paper is to empirically investigate the impact of corruption on foreign direct investment (FDI) and its two major modes of entry: greenfield investment (greenfield) and cross-border mergers and acquisitions (M&As).

Design/methodology/approach

Data are collected from 131 countries. Modern econometric techniques, including the generalized method of moments (GMM) estimator, two-stage least square estimator and two-step system GMM estimator, are used to evaluate the impact of corruption on FDI activities.

Findings

The empirical results illustrate that corruption is a deterioration factor that significantly hinders FDI inflows. However, this finding turns out to be contradictory when the two major components of FDI – greenfield investment and cross-border M&As – are separately examined. Specifically, while corruption consistently discourages cross-border M&As over time, it appears to exert positive effect on greenfield investments.

Originality/value

This is among the first to empirically examine the impact of corruption on FDI and its modes of entry in a number of countries spanning different time windows. In this sense, this paper also captures the changing nature of societies and economic conditions overtime and, therefore, enable academic researchers, policy-makers and business practitioners to draw broad inferences from the empirical results.
