Abstract

Purpose

The purpose of this paper is to study the curing mechanisms, anticorrosive properties and protective mechanisms of three kinds of amine curing agents applied in a new kind of light colored water‐borne epoxy antistatic anticorrosive paint.

Design/methodology/approach

Using light color‐conductive mica, titanium oxides and environmentally‐friendly anticorrosive pigments in the two‐component water‐borne epoxy system, the light colored water‐borne antistatic anticorrosive paint was prepared. The molecular structure and curing mechanisms of the curing agents was analyzed by Fourier transform infra‐red spectroscopy, and the influence of the curing agents on anticorrosive properties and protective mechanisms was studied by electrochemical impedance spectroscopy.

Findings

The paints cured by the modified amine curing agent possessed optimal integrated properties with a coating surface resistivity of 106 Ω and the best anticorrosive performance.

Originality/value

A novel light colored water‐borne epoxy antistatic anticorrosive paint cured by the optimal curing agent could be used in corrosion protection for oil tanks to replace the traditional oil‐based antistatic anticorrosive paints.

Abstract

Purpose

This paper aims to collect and compile the historical data of Guanfu Salt Farm, officially built by the Song Dynasty (960–1279) within modern Hong Kong territories, to reconstruct its history for the reflection of Hong Kong society of the time.

Design/methodology/approach

This paper is largely based on identification and analysis of historical documents, including keyword search on electronic databases and verification with the original sources, with reference to archaeological findings when necessary.

Findings

This paper reconstructs the history of Guanfu Salt Farm based on documentary sources with reference to archaeological findings. English translation of Chinese sources is also provided when necessary.

Originality/value

There has been an absence of systematic compilation of historical data of Hong Kong during the Song Dynasty, which are limited in quantity and scattered across different sources. This paper seeks to fill the vacuum of knowledge about pre-colonial Hong Kong, with a more comprehensive reconstruction of the history of Guanfu Salt Farm.

Abstract

Purpose

The purpose of this study is to investigate the relationship between social loafing behaviour, self-concept and perceived organisational politics (POP). The impact of POP and self-concept upon social loafing behaviour has been the fundamental focus of the paper.

Design/methodology/approach

Data were collected from four companies (n = 262) that combined the responses of subordinates and supervisors. The consequent impact of self-concept factors and POP on social loafing behaviour was analysed through correlations; multiple regressions and mediation were tested using Barren–Kenny and Hayes Bootstrap methods.

Findings

A positively significant connection among self-concept, social loafing and POP has been found in this study. The findings show that POP significantly mediates the relationship between social loafing and self-concept.

Research limitations/implications

This study provides evidence of the positive relationship among POP, social loafing behaviour and self-concept. Such knowledge derived may facilitate the scientific task allocation process, feedback system, team orientation, individual differences and job choice aspects, and thus help in the essential understanding of withdrawal work behaviour and perceived organisational support variables.

Practical implications

Productivity and employee satisfaction are major concerns for all organisations. This research paper provides insight to the organisations and supervisors about individual loafing attitude, self-concept and organisational politics and suggests to overcome their impact and improvement in productivity and employee satisfaction.

Originality/value

This is a pioneer paper in the sense that previously there has been no attempt to determine the relationship between POP and social loafing behaviour. Past research has mostly been conducted in the laboratory settings or classroom contexts. The longitudinal data used in this study remove prior research drawbacks and enlighten the unexplored relationships.

Abstract

Purpose

This paper aims to theoretically investigate a knowledge management model from the combined perspective of knowledge acquisition and knowledge application and its effect on organizational performance.

Design/methodology/approach

This study reviews prior research on knowledge acquisition and knowledge application, puts forward the concepts of “the extensiveness of knowledge acquisition” and “the concentration of knowledge application” and more importantly proposes an integrated model by combining these two dimensions. Four case examples of enterprises are subsequently described and analyzed to illustrate the sources of knowledge acquisition, the objects of knowledge application and their influences on organizational performance.

Findings

Four knowledge management modes and their impacts are confirmed in this study. Specifically, the organization of the turbojet engine mode (high extensiveness of knowledge acquisition and high concentration of knowledge application) can achieve good performance. The pipeline mode (high extensiveness of knowledge acquisition and low concentration of knowledge application) is the second, which has limited influence on good organizational performance. Organizations with the flashlight mode (low extensiveness of knowledge acquisition and high concentration of knowledge application) can achieve limited performance under the appropriate environment. The candle mode (low extensiveness of knowledge acquisition and low concentration of knowledge application) is the worst, performance of which is poor due to the break of the knowledge chain.

Practical implications

This paper holds that organizations should actively use the turbojet engine mode, adopt the pipeline mode and the flashlight mode cautiously, and avoid falling into the candle mode.

Originality/value

To the best of the authors’ knowledge, this study is among the first to propose the concepts of “the extensiveness of knowledge acquisition” and “the concentration of knowledge application,” and provides a combined model for analyzing differences in organizational performance from the perspective of knowledge.

Abstract

Purpose

The purpose of this paper is to examine how relative abusive supervision (i.e. team member’s perceived abusive supervision as compared with the team mean) influences team member’s job attitudes through the mediating role of relative leader–member exchange. This study also explores the cross-level moderating roles of team-level abusive supervision and team-level leader–member exchange (LMX) in the process.

Design/methodology/approach

This study used two-wave data from 1,479 employees in 145 work teams, and tested a cross-level moderated mediation model using multilevel structural equation modeling.

Findings

Results demonstrate that the negative indirect effects of relative abusive supervision on job satisfaction and team affective commitment through relative LMX are stronger when team-level abusive supervision is low rather than high.

Originality/value

Integrating LMX theory with a relative deprivation perspective, this study conceptualizes and operationalizes relative abusive supervision, develops an individual-within-group model of abusive supervision’s consequences in teams and demonstrates a cross-level moderating effect of team-level abusive supervision in buffering relative abusive supervision’s negative consequences.

Abstract

Purpose

The authors propose a new motivation construct, political self-efficacy, and investigate how and when leader political mentoring influences follower political behavior and promotability through political self-efficacy.

Design/methodology/approach

The authors collected four samples to develop a scale for political self-efficacy and conducted two field studies of leader-follower dyads to examine the model.

Findings

Leader political mentoring enhances followers' political behavior and promotability through increasing their political self-efficacy. These positive indirect effects are stronger when followers have a higher positive political perception.

Originality/value

This study integrates mentoring research with organizational politics literature and theorizes how a domain-specific self-efficacy—political self-efficacy, translates the positive impact of leader political mentoring on constructive behavioral and career-related outcomes.

Abstract

Purpose

How do institutional pressures influence the cluster firm’s innovation? Institutional pressure consists of regulative, normative and cognitive pressures; most scholars have only focused on the influence of regulative pressure as institutional environment on innovation. In addition, the nature of strategic cognition, as the mediator act on innovation strategy, remains underexplored in the literature. Based on institution theory and ambidextrous innovation theory, this study aims to propose a framework to examine the mechanism of institutional pressures acting on ambidextrous innovation through the moderated mediating role of strategic cognition in clusters.

Design/methodology/approach

Using survey data collected from 422 sampled firms in China, regression models were used to test hypotheses from the mediating role of strategic cognition between institutional pressures and cluster firm’s ambidextrous innovation.

Findings

The results showed that regulative, cognitive pressures and, especially, normative pressures have significant positive effects on cluster firms’ ambidextrous innovation. Strategic cognition presented by prospector and analyzer mediates the relationship between institutional pressure and ambidextrous innovation except defender; dynamic environment positively moderates the mediating effects of prospector cognition on explorative innovation, and negatively moderates the mediating effects of analyzer cognition on exploitative innovation.

Originality/value

The findings of this study have some implications that strategic cognition played a partially meditating role between the institutional pressure and ambidextrous innovation. Government should construct a dynamic innovation policy system according to the resource endowment in different regions; furthermore, classification support system to cluster firms with different strategic cognition should be built.

Abstract

Purpose

The purpose of this paper is to reveal the identification-based mechanisms through which servant leadership affects desired outcomes (organizational citizenship behavior (OCB) toward coworkers and turnover intention) in the service industry in China.

Design/methodology/approach

The data of 293 pairs of valid subordinate-supervisor dyads were collected from the hospitality industry in China with a time lag of 30 days to reduce common method bias. Hypotheses were tested by a bootstrapping method and rival model comparisons.

Findings

The authors demonstrate that both the subordinate’s identification with the supervisor and identification with the organization play crucial roles in translating servant leadership’s effects to subordinate’s coworker-oriented OCBs and turnover intention. However, the occurrence of the two identifications seems to be not parallel but in sequence (i.e. pointing from identification with the supervisor to identification with the organization). In addition, results show that servant leadership’s ability to reduce subordinate’s fear of being close to the immediate supervisor is an equally significant route through which subordinate’s identification with the organization can be established.

Originality/value

The research has extended the literature and provided a nuanced explanation of the identification processes underlying servant leadership. The differentiation between relational identification with supervisor and collective identification with organization has shed light on a socialization mechanism through which subordinates come to demonstrate other-oriented service behavior and choose not to leave the organization. Additionally, the way that servant leadership helps eliminate subordinate’s fear in a supervisory relationship has proved to be in-negligible in enhancing organizational identification.

Abstract

Purpose

The purpose of this paper is to find an omnidirectional robust gust response stabilization (GRS) scheme with anti-disturbance and state-limited features.

Design/methodology/approach

Disturbance observer and barrier Lyapunov techniques, which can, respectively, estimate the lumped disturbances of the dynamic system in real-time and ensure the middle states within some prescribed ranges according to some flight safety indexes.

Findings

In the existing literature, almost all of the GRS controllers are either only for the longitudinal dynamics or only for the latitudinal dynamics. Few studies have considered the gust response alleviation problem with omnidirectional wind disturbance and full aircraft model.

Originality/value

This paper proposes a fresh scheme to deal with a more holistic GRS problem; the disturbance observer based (DOB) barrier Lyapunov backstepping longitudinal controller has been put forward; DOB nonlinear dynamic inversion to handle the multi-input-multi-output lateral dynamics; and to closely connect the two loops of the latitudinal dynamics, a manipulating variable conversion method is proposed.

Abstract

Purpose

This paper aims to analyse how both Lin’s birthplace identity and his Christian identity contributed to his fruitful public career and to ascertain which identity became the most significant.

Design/methodology/approach

Archival research is the main method used in this paper. The most important archives drawn from are the Daniel Tse Collection in the Special Collection and Archives of the Hong Kong Baptist University Library. Oral history has also been used in this paper to uncover more material that has not yet been discussed in existing scholarly works.

Findings

This paper argues that although Lin’s birthplace identity and social networks helped him to start his business career in Nam Pak Hong and develop into a leader in the local Chaozhou communities, these factors were insufficient to his becoming a respectable member of the Chinese elite in post-war Hong Kong. He became well known not because of his leading position in local Chaozhou communities or any great achievement he had obtained in business but because of his contribution to the development of Christian education. These achievements earned him a reputation as a “Christian educator”. Thus Lin’s Christian identity became more important than his birthplace identity in contributing to his successful public career.

Originality/value

This paper has value in showing how Christian influences interacted with various cultural factors in early Hong Kong. It also offers insights into Lin’s life and motivations as well as the history of the institutions he contributed to/founded. It not only furthers our understanding of the Chinese Christian business elite in early Hong Kong but also provides us with insights when further studying this group of people in other British colonies in Asia.
