PurposeThis study aims to investigate the influence of human resource management (HRM) practices on two aspects of innovation capability namely product and process innovation. It also attempts to clarify the HRM-innovation relationship by examining the mediating roles of specific components of knowledge management capability (KMC) namely knowledge acquisition, knowledge sharing and knowledge application.Design/methodology/approachThis research used the quantitative method and structural equation modeling (SEM) approach to examine hypotheses with data obtained by survey from 325 participants in 98 Vietnamese firms.FindingsThe empirical findings show the evidence on the mediating roles of components of KMC in the HRM-innovation relationship and indicate that HRM practices have a greater impact on product innovation compared to its effects on process innovation. In contrast, all three components of the KMC produce larger impacts on process innovation than on product innovation. In particular, it highlights the key role of knowledge sharing in predicting product and process innovation in comparison to the roles of knowledge acquisition and knowledge application.Practical implicationsCEOs/managers should practice and manage their human resource to foster organizational capability for product and process innovation directly or indirectly via enhancing aspects of KMC namely knowledge acquisition, sharing and application.Originality/valueBy investigating the mediating mechanisms of specific components of KMC, the paper has significantly contributed to advancing the body of knowledge of innovation theory and providing deeper insights on the correlation between HRM practices and aspects of innovation capability namely product and process innovation.
Purpose Drawing on social exchange theory, this paper aims to clarify the influences of ethical leadership (EL) on knowledge-sharing (KS) behaviours of employees through the mediating roles of affective- and cognitive-based trust in leadership. This work further offers deeper insight into the moderating mechanism of distributive justice in the EL–KS relationship. Design/methodology/approach Structural equation modelling (SEM) is used to investigate the influential degree of EL, aspects of employee trust in leadership and distributive justice on employee behaviours towards tacit and explicit knowledge via data collected from 339 participants in 75 Vietnamese firms. Findings The empirical findings reveal that employee trust in leadership positively mediates the relationship between EL and KS behaviours. In particular, distributive justice significantly fosters the impacts of EL on tacit and explicit KS behaviours. Practical implications Managers and practitioners should strengthen EL practices to build and maintain employee trust in them for promoting KS behaviours. In addition, research highlights the necessity of establishing distributive justice in organisations to enhance the effect of EL on KS behaviours of employees. Originality/value This paper is unique in its attempts to advance the insights on the theory of leadership and knowledge management by investigating the different moderated-mediation mechanisms in the relationship between EL and specific aspects of KS behaviours.
Purpose The purpose of this paper is to examine the determinants of mutual funds’ performance at both a country level and a fund level in Vietnam. Design/methodology/approach The different types of funds with more than three-year operation are selected to remove outliers of the stock market boom from 2015 to 2018. The data set includes 54 mutual funds operating during the period from 2008 until November 2018. Findings The research finds that there is a positive relationship between macroeconomics and mutual funds’ performance. Furthermore, country-level governance such as regulation effectiveness, political stability, economic growth and financial development has a positive correlation with mutual funds’ performance. However, the impact of fund-level factors is diverse with the no significant impact of board size on mutual fund’s performance, while passive funds perform better than active funds in Vietnam. Practical implications The research results suggest that investors should pay attention to the types of funds and operating expense when making an investment decision in mutual funds. There are some recommendations for both government policy-makers and the mutual fund industry that are likely to facilitate the development of this field in Vietnam. Originality/value The research contributes to the understanding of what are the factors that should be considered when investing in mutual funds.
The topic of CEO compensation has been highly debatable. The financial crisis of 2008 further prompted public and media to question executive compensation practices in the United States. This study investigates the effect of the financial crisis on CEO compensation and also examines various determinants of CEO compensation. Using a sample of Fortune 500 firms and 2241 observations, we find that financial crisis has a small but significant effect on CEO compensation. Firm performance, firm size, and CEO duality were found to have a significant effect on CEO compensation both pre and post-crisis. One major difference found between pre and post-crisis was in the composition of pay. While cash compensation decreased significantly post-crisis, equity-compensation increased.
This research is a continuation of the previous research on the simulation of Low Density Polyethylene reactors. The main focus of this research is the stability of the simulation and the optimization of the polymerization to decrease decomposition. Polymerization is a very complex reaction with multiple stages. There are three main stages this research is concentrated about: Polyethylene production, Ethylene decomposition, and Initiator (Acetylene) decomposition. If decomposition occurs, there is a chance of explosion due to the decomposition reaction being exothermic and violent. ANSYS Fluent is a computational fluid dynamics, CFD, software capable of simulating these reactions. The tubular reactor consists of a pipe and an injection port. There are many variables in this reaction that can be manipulated to produce a result such as injection speed and mass fractions of chemical components. The stability of the simulation was insured using a new method, “Jumpstart”, which involves initially injecting an infinitesimally small amount of the decomposition products, in order to successfully trigger decomposition.
