Abstract

Purpose

This study aims to design a novel seasonal discrete grey model for forecasting monthly natural gas consumption by incorporating damping accumulation and time-polynomial term.

Design/methodology/approach

Considering the principle of new information priority and nonlinear patterns in the original series of monthly natural gas consumption, we establish a novel discrete seasonal grey model by adding the damping accumulation and time-polynomial term into the existing model. In addition, the order of damping accumulation and the coefficient of time-power term can be determined by the moth flame optimization (MFO) algorithm.

Findings

The empirical cases show that the proposed model has a better prediction performance when compared with other benchmark models, including six seasonal grey models, one statistical model and one artificial intelligent model. Based on forecasts, the proposed model can be considered a promising tool for monthly natural gas consumption (NGC) in US.

Originality/value

By combining the damping accumulation and the time-polynomial term, a new discrete seasonal grey model for improving the prediction performance of the existing grey model is proposed. The properties of the proposed model are given, and the newly-designed model is initially applied to predict monthly NGC in US.

Abstract

Purpose

A new method for forecasting wind turbine capacity of China is proposed through grey modelling technique.

Design/methodology/approach

First of all, the concepts of discrete grey model are introduced into the NGBM(1,1) model to reduce the discretization error from the differential equation to its discrete forms. Then incorporating the conformable fractional accumulation into the discrete NGBM(1,1) model is carried out to further improve the predictive performance. Finally, in order to effectively seek the emerging coefficients, namely, fractional order and nonlinear coefficient, the whale optimization algorithm (WOA) is employed to determine the emerging coefficients.

Findings

The empirical results show that the newly proposed model has a better prediction performance compared to benchmark models; the wind turbine capacity from 2019 to 2021 is expected to reach 275954.42 Megawatts in 2021. According to the forecasts, policy suggestions are provided for policy-makers.

Originality/value

By combing the fractional accumulation and the concepts of discrete grey model, a new method to improve the prediction performance of the NGBM(1,1) model is proposed. The newly proposed model is firstly applied to predict wind turbine capacity of China.

Abstract

Purpose

The purpose of this paper is to explore the origin of the development of insolvency laws in China and Russia and explores the evolving role of the states in the legislative process.

Design/methodology/approach

The study is conducted based on the analysis of historical materials and the relevant secondary sources written in Chinese and Russian.

Findings

The paper argues that the development of the insolvency laws in China and Russia underlines the diverging perceptions by the states about the ways to improve economic performance through reforming their respective state enterprise system. On the other hand, the unsatisfactory utilisation of the laws in the these countries revealed the incompleteness of the wider institutional reform that opened up possibilities for predatory exploitations and corruptive practices which in turn upset the market-building in these developing economies.

Originality value

This study highlights that by bring back the state into the analysis, the competing ideas, interests and institutions in the development of insolvency laws can be identified.

Abstract

Purpose

This paper proposes a framework for director evaluation in the context of Chinese state-owned enterprises (SOEs), taking into account the influences of traditional and modern Chinese ideologies.

Design/methodology/approach

Following the Delphi method, a series of semi-structured interviews were conducted with Chinese SOE directors.

Findings

The framework used has been validated by examining seven dimensions of virtue and four dimensions of competence functions in Chinese SOEs. Effective and representative characteristics of each dimension are identified through interviews.

Originality/value

First, through this research, indicators of virtue have been materialized and those of competence have been specified in a broader range. Second, this research provides advice for training of candidate directors whose experience were in private firms before they step in as SOE directors.

Abstract

Purpose

This editorial essay aims to focus on research integrity and commitment to excellence by analyzing the transitioning symptom associated with the Chinese research community as causes for concerns in research ethics and misconduct. The authors highlight their editorial process and practice in safeguarding research integrity at JCHRM and address related ethical issues on duplicate submissions in relation to their editorial experience.

Design/methodology/approach

This article adopts an approach combining literature review and reflexive analysis.

Findings

The current academic misconduct and ethical concerns in China are caused by a number of concurrent counterforces: increased attractive opportunities in moonlighting; research mindset rooted in the traditional learning orientation on imitation and contemporary education on rote learning; and heightened publication‐based performance requirement enforced by the government and institutions. These counterforces are further complicated by the ongoing socio‐cultural context, e.g. the drinking and eating culture. The authors report their editorial steps in safeguarding research integrity and commitment to excellence. In relation to submitting translated published papers to an English journal, they emphasize that originality is the core. They are committed to facilitate the transition of Chinese HRM research community to conform to the international standard.

Originality/value

This article links professional ethics, research integrity, and commitment to excellence to developing Chinese scholarly human resources. It articulates specific goals, principles, and responsibilities of JCHRM editorial practices for promoting high‐quality Chinese HRM research.
