Abstract

Purpose

The purpose of this paper is to study the failures spread in complex power grids, and what topology of power grids is best for preventing or reducing blackouts.

Design/methodology/approach

Based on the study of cascading failure models of complex power networks, an extended dynamical cascading failure model is proposed. Based on this model, two representatives of the complex power grids, the small‐world network and the scale‐free network, were simulated for line cascading failure. The power loss caused by cascading failures and the spreading speed of cascading failure are discussed.

Findings

Power loss caused by cascading failures in the small‐world network is much larger than that in the scale‐free network, and the speed of cascading failure propagation in the small‐world network is much faster than that in the scale‐free network.

Research limitations/implications

The establishment of the dynamical cascading failure model considering other protection devices needs further study.

Practical implications

The results of this study can be beneficial in system planning and upgrading.

Originality/value

An extended dynamical cascading failure model is proposed and cascading failures in different topology of power grid are discussed.

Abstract

Purpose

The purpose of this paper is to design an open architecture of an interconnected communication system (ICS) for multi‐level electric power control centers (EPCC) based on Tele‐control Application Service Element (TASE.2), which possesses specialties of high performances, robustness, cost‐efficiency, quick‐restoration, and easy‐maintenance.

Design/methodology/approach

Based on the hierarchy and structure of TASE.2, the overall architecture of the ICS for multi‐level EPCC is put forward at first. As the key devices in the system, the structures of the communication gateway (CG) and common interface are designed. Then, the logical procession flows in CG and the con modes, for both CG and IC are analyzed in detail. The web‐based software configuration of remote maintenance and fault diagnosis is discussed conceptually.

Findings

As a standardized, well‐developed, and efficient protocol, TASE.2 is considered to be the most suitable protocol to support the ICS for multi‐level EPCC.

Research limitations/implications

The performance of the ICS needs to be further simulated.

Practical implications

Practical architecture for ICS for multi‐level EPCC with robustness and cost‐efficient specialty is designed in principle, which is very useful for manufacturers to develop pilot devices or even products.

Originality/value

This paper proposes a new ICS scheme for multi‐level EPCC based on TASE.2 is proposed.

Abstract

Purpose

Overqualification is a growing concern for employers in many countries. The practice of mismatching employees and positions inevitably leads to an increase in organizational training and management costs. This study can not only further enrich the theoretical achievements in the field of human resource management, but can also provide a reference for enterprise managers on how to effectively stimulate employees' innovative behaviour.

Design/methodology/approach

503 questionnaire responses were analysed using SPSS 24.0 and Mplus 8.0.

Findings

It was concluded that, (1) perceived overqualification is negatively related to employees' innovation behaviour (β = −0.32, p < 0.001); (2) psychological contract breach and psychological distance partially mediate the relationship between perceived overqualification and employees' innovation behaviour. Among them, the mediating effect of psychological contract breach was −0.14 (p < 0.01), and that of psychological distance was −0.12 (p < 0.001); the chain-mediating effect of psychological contract breach and psychological distance was −0.09 (p < 0.01); (3) employment relationship atmosphere played a moderating role in the relationship between perceived overqualification and employees' innovation behaviour (β = 0.04, p < 0.01).

Originality/value

This study verifies the negative impact of perceived overqualification on employee innovation behaviour and reveals the mediating role of psychological factors between the two. It also discusses the moderating effect of employment relationship climate on the relationship between perceived overqualification and employees' innovation behaviour.

Abstract

Purpose

This paper aims to examine the occurrence and management of conflict in Chinese organizations, from an emic perspective. The authors provide an in-depth understanding of Chinese working adults’ lived experiences regarding workplace conflicts.

Design/methodology/approach

The study is a qualitative one, consisting of open-ended questionnaires administered to 55 Chinese nationals who worked in governmental, public or international organizations in China. A thematic analysis of the answers was conducted.

Findings

Chinese participants adopted a normative mental model that defined their preferred “way of doing” things. A skillful balance was expected in conflict management that incorporated integrated open communication and strategic silence. Chinese working adults emphasized maturity in the workplace and the recognition of shared goals.

Research limitations/implications

The online questionnaire format may have constrained participants’ responses. Also, the data were collected from various organizational contexts, but there were not enough participants from each type of organization so that comparisons between institutions could be made.

Practical implications

The results could help expatriate populations better prepare their lives abroad in China. Also, the findings could aid organizational or management consultants who work closely with Chinese partners.

Social implications

The findings enhance our understanding of how Chinese working adults deal with workplace conflicts and the circumstances in which conflicts arise in the workplace, which also reflected the social and cultural contexts of the Chinese workplace experience.

Originality/value

This study provides an alternative interpretation of workplace conflicts and their management in China that is anchored in the unique organizational and national cultural context. They constitute the base for future development of culture-based explanations of Chinese organizational conflict behaviors.

Abstract

Purpose

The modernization of China’s economy is an integral part of Chinese-style modernization. According to the principle of unifying theoretical, historical and practical logic, theoretically explaining the modernization of China’s economy is both a political necessity and a higher scientific requirement.

Design/methodology/approach

Following this evolutionary line – from modes of production to the general economic development mechanism and then to patterns of economic operation and development – this paper employs the principal contradiction analysis method to offer an interpretation of China’s economic modernization from the broad Marxist political economy perspective.

Findings

In economic terms, “get organized” primarily refers to the development and mutual promotion of team-based and market-based division of labor organizations, as discussed by Karl Marx. “Get organized” (specifically the development of team-based division of labor organizations) acts as the engine of China’s economic modernization and serves as the historical logical starting point. Division of labor is the theoretical logical starting point for interpreting China’s economic modernization. The two of them are congruent, achieving the unity of theoretical and historical logic at the starting point. The development and mutual promotion of these “two types of division of labor” inherently generate the general mechanism of economic development first comprehensively discussed by Marx and Friedrich Engels, which involves the division of labor development and market expansion accumulating cyclically and reinforcing each other. This mechanism drives both the high-speed and high-quality development of China’s economic modernization.

Originality/value

The broad Marxist political economy paradigm facilitates explaining China’s economic modernization theoretically, historically and practically with unified logic. “Get organized” serves as both the engine and the realization mechanism of this modernization, with the Communist Party of China (CPC) consistently being the core force of this organizational effort.
