Abstract

Purpose

The melamine milk scandal caused a crisis of confidence in food containing dairy products. The purpose of this paper is to explore the determinants of precautionary behaviour to avoid food containing dairy products among Taiwanese college students.

Design/methodology/approach

Of the total respondents selected using a multistage cluster sampling plan, 1,213 respondents completed the questionnaire.

Findings

The survey results showed that subjective norms, attitude, perceived behavioural control, attention to news, and perceived credibility of information are significantly associated with the intention to take precautionary behaviour.

Originality/value

The paper developed a modified theory of planned behaviour (TPB) that focused on attention and perceived credibility of milk scandal‐related information as additional determinants of precautionary behaviour to avoid food containing dairy products. The inclusion of attention and perceived credibility of information constructs enabled a better model fit than that of the TPB model.

Abstract

Purpose

This study aims to investigate the relationship between prevention and panic of COVID-19 and distress tolerance, happiness and emotional intelligence (EI) in undergraduate and postgraduate accounting students in Iraq. In other words, this study seeks to answer whether or not different types of prevention and fear of COVID-19 can lead to improved distress tolerance, happiness and EI.

Design/methodology/approach

The study’s statistical population comprises 298 undergraduate and 138 postgraduate students in Iraq who were selected as the sample size using the Cochran sampling method. In this study, partial least squares regression (PLS) have been used to investigate the effect of independent variables on the dependent variable.

Findings

The results showed a positive and significant relationship between COVID-19 prevention and distress tolerance and happiness, but no significant relationship was observed between COVID-19 prevention and EI. Also, no significant relationship was observed between fear of COVID-19 and distress tolerance and happiness, but there was a positive and significant relationship between fear of COVID-19 and EI.

Originality/value

The present study’s results can provide valuable information to everyone and help the development of science and knowledge because so far, and to the best of the authors’ knowledge, no research has examined the impact of prevention and panic of COVID-19 on distress tolerance, happiness and EI in students.

Abstract

Purpose

The purpose of this paper is to develop a proportional-integral-derivative-based fuzzy neural network (PIDFNN) with elitist bacterial foraging optimization (EBFO)-based optimal membership functions (PIDFNN-EBFO) position controller to control the voice coil motor (VCM) for tracking reference trajectory accurately.

Design/methodology/approach

Because the control characteristics of the VCM are highly nonlinear and time varying, a PIDFNN, which integrates adaptive PID control with fuzzy rules, is proposed to control the mover position of the VCM. Moreover, an EBFO algorithm is further proposed to find the initial optimal fuzzy membership functions for the PIDFNN controller.

Findings

Due to the gradient descent method used in back propagation (BP) to derive the on-line learning algorithm for the PIDFNN, it may reach the local optimal solution due to the inappropriate initial values. Hence, a hybrid learning method, which includes BP and EBFO algorithms, is proposed to improve the learning performance of the PIDFNN controller.

Research limitations/implications

Future work will consider reducing the computational burden of bacterial foraging optimization algorithm for on-line parameters optimization.

Practical implications

The real-time control system is implemented on a 32-bit floating-point digital signal processor (DSP). The experimental results demonstrate the favorable effectiveness of the proposed PIDFNN-EBFO controlled VCM system.

Originality/value

A new PIDFNN-EBFO control scheme is proposed and implemented via DSP for real-time VCM position control. The experimental results show the superior control performance of the proposed PIDFNN-EBFO compared with the other control systems.

Abstract

Purpose

This article provides the first systematic review of literature on effective organisational practices for reducing innovation project uncertainties to promote project performance. Innovation is the lifeblood of organisations, while simultaneously being one of the most challenging processes to manage. This systematic review seeks to examine best practice for reducing uncertainties and thus mitigate the high failure rates in innovation projects.

Design/methodology/approach

This paper provides a systematic review of the literature on innovation project management and encourages an understanding of how intra-organisational collaboration reduces uncertainty and thus increases project performance.

Findings

Based on an analysis of the systematic literature review findings, the impact of intra-organisational collaboration in reducing uncertainties in innovation projects is uncovered. Three types of project uncertainties were found to be dominant in the context of innovation project management: task, technological and market uncertainties. Five dimensions of intra-organisational collaboration are also identified, namely collaborative relationship, collaborative leadership, communicating and sharing information, trust formation and joint decision-making.

Originality/value

The authors situate five intra-organisational collaboration dimensions as key mechanisms that yield organisational learning as an outcome. On the other hand, they also uncovered that organisational learning is a key enabler in the relationship between intra-organisational collaboration and task, market and technological uncertainties reduction. Therefore, intra-organisational collaboration is identified as a critical practice in enhancing the performance of innovation projects. The study proposes a multi-dimensional conceptual model, providing a mechanism for furthering a research agenda for improving the performance of innovation projects.

Abstract

Purpose

Customer acquisition and retention methods are the most critical issues for any enterprise. By identifying potential customers and targeting them through marketing activities, enterprises can minimize marketing costs and maximize transaction probability. However, because market surveys are labor- and time-consuming, and data mining is ineffective for obtaining competitor data, enterprises may be unable to understand real-time changes in market trends and consumer preferences. The paper aims to discuss these issues.

Design/methodology/approach

This study developed a mechanism that automatically searches for potential customers in virtual communities. In addition, a common product attribute (CPA) model was developed based on the five dimensions of the theory of consumption values and a questionnaire survey was conducted to verify the corresponding relationships. Subsequently, the authors quantified and applied the relationship between the proposed CPA model and consumption values theory.

Findings

During the experiment, functional and social values yielded more accurate predictions. Contrary to our expectations, emotional value yielded an inaccurate prediction of potential customers. The overall precision was 0.74, with a threshold of 0.5.

Research limitations/implications

Due to each industry including the distinctive characteristics and attributes regarding its products, the methods and models were only adopted in food industry for testing effectiveness.

Practical implications

Considering the food industry as an example, this study adopted the case study method to screen potential customers based on 400 articles from virtual communities, and combined a latent semantic analysis method with a backpropagation neural network to verify the effectiveness of the proposed method.

Originality/value

By adopting the proposed enterprise-product profile model, enterprises can compile basic information related to their products and industry. The proposed system can be used by enterprises to identify potential customers in areas with potential for market development.

Abstract

Purpose

The purpose of this paper is to explore the association between corporate governance (CG) mechanisms and the extensiveness of carbon disclosure.

Design/methodology/approach

This paper uses Ordinary Least Squares (OLS) regression model with data from 2009 to 2012 for largest Australian companies that voluntarily disclose their information to the carbon disclosure project.

Findings

The authors find that board independence, board diversity and managerial ownership are significantly correlated with the degree of carbon transparency, while the existence of environmental committee is not.

Practical implications

The findings of this paper should be useful for government and capital market regulators who concern the quality of CG and carbon actions. First, the evidence in this paper suggests that current CG practice that emphasize board diversity and independence seems encouraging an environment friendly decision and adopt carbon reduction initiatives. Second, however, the current version of CG codes need more stress on none financial goals that should help corporate executives to balance value enhancement vis-à-vis ecosystem protection. Finally, another implication for policy-makers is CG should be re-structured so as to motivate firms to pursue long-term sustainable development instead of taking short-sight view of firm performance.

Originality/value

This paper contributes in the increasing body of literature indicating that CG encourages a proactive corporate strategy in general and carbon disclosure in particular. The authors add new empirical evidence which has policy implication that CG should be improved so as to encourage executives to engage in more sustainable development and stakeholder long-term value protection.

Abstract

Purpose

The purpose of this study was to investigate the participants' attitudes toward the ethical issues caused by collecting social media data (SMD) for research, as well as the effects of familiarity, trust and altruism on the participants' attitudes toward the ethics of SMD research. It is hoped that through this study, scholars will be reminded to respect participants and engage in ethical reflection when using SMD in research.

Design/methodology/approach

This study adopted social media users as its research subjects and used Sina Microblog, the world's largest Chinese social media platform, as the example. Based on the 320 valid responses collected from a survey, structural equation modeling was employed to examine the research model.

Findings

The results indicated that altruism, familiarity and trust have significant influences on participants' attitudes toward the ethics of SMD research, and familiarity also influences attitudes through the mediating role of trust and altruism.

Originality/value

This study explored the mechanism underlying the relationship between the determining factors and participants' attitudes toward the ethics of SMD research, and the results demonstrated that the informed consent mechanism is an effective way to communicate with participants and that the guiding responsibility of the platform should be improved to standardize SMD research.

Abstract

Purpose

This study aims to develop a new method to treat the numerical singularity at the critical nodes of two skew coordinates, and optimize the leakage of micro herringbone grooved journal bearings (MHGJBs) with this method.

Design/methodology/approach

A side leakage numerical algorithm is proposed by using the skew meshes with a virtual node (SMVN) method to evaluate the effects of groove angle, bank/groove ratio, groove depth and groove number on load capacity, friction and side leakage of MHGJB.

Findings

The SMVN method is effective in treating the numerical singularity at the critical nodes of two skew coordinates. Besides, a group of optimized parameters of micro herringbone groove is obtained which can not only minimize the side leakage but also improve the load capacity and friction force.

Originality/value

A virtual node method was proposed, which can significantly improve the calculation accuracy in the side leakage model.

Abstract

This study develops an environment, social, and governance (ESG) momentum strategy by combining information about ESG scores and the momentum effect. This study, subsequently, applies the ESG momentum strategy to Taiwanese and Japanese stock markets and investigates the performance of the ESG momentum strategy in each market. Detailed comparisons of the ESG scores and ESG momentum performance between the two markets are conducted. The empirical results show that the ESG momentum strategy can obtain enhanced profits in the Taiwanese market, while the ESG momentum strategy cannot lead to substantial profits in the Japanese market. In addition, the ESG momentum effect in the Taiwanese market can last for three years after portfolio formation. In the Japanese market, the ESG contrarian strategy may deliver better profits than the ESG momentum strategy.
