Abstract

Purpose

As Chinese massage is increasingly popular, many physicians are needed these days. In order to promote the experience and skills of experts and reduce labour intensity during massage, a massage robot, which could reproduce the expert techniques with individualized manipulation parameters and enhanced safety control strategies, is presented in this paper.

Design/methodology/approach

The kinematic and force features of key massage techniques, such as Thumb Kneading, Pressing, Rolling, Vibrating and Pinching, are summarized by analyzing the massage processes of expert physicians, and a mathematical model for robotic massage is established. With safety issues taken into account, the overall system structure of the massage robot is proposed. The system generally consists of a positioning platform and a massage end‐effector which implements the massage techniques, and the end‐effector is further divided into a parallel mechanism and a massage hand to accommodate different techniques. Visual tracking is used for positioning acupuncture points by recognizing markers on a massage vest worn by the patient. A pain threshold value is introduced to individualize therapy schemes and a force‐position control method based on the pain threshold is presented.

Findings

VAS (Visual Analogue Scale) tests for lumbar muscle strain are carried out using the massage robot, and the treatment effect of the massage robot based on traditional Chinese massage therapy theory is initially validated.

Research limitations/implications

The treatment effect of the massage robot needs to be assessed clinically for more occasions and more clinical experiments will be conducted, to optimize the configuration and control strategy to meet the clinical needs in future work.

Originality/value

The robotic massage system presented in this paper is acting on acupuncture points based on traditional Chinese massage therapy theory, with human manipulation techniques reproduced and expert experiences incorporated. The massage robot can take the place of a massager to perform Chinese massage. Most of the massage robotic systems published in the world perform only one massage technique and the whole massage process is not completely considered. By comparison, the authors' massage robot could perform five techniques. Furthermore, the authors have designed the procedure of robotic massage specifically for patients who suffer from lumbar muscle strain.

Abstract

Purpose

The classification of aircraft failures has been a significant part of functional hazard analysis (FHA). Aiming at the shortcomings of the traditional FHA method in the evaluation of aircraft risk, the purpose of this paper is to put forward a new approach by combining the gray comprehensive relation calculation method in the gray system theory with the traditional FHA in order to deal with the problem of “little data, poor information.”

Design/methodology/approach

This paper combines FHA, 1–9-scale method and gray relation analysis. At first, aircraft failure scenarios are chosen and data from experts are collected; then gray system theory is applied to find the relevance of such scenarios. Finally, the classification according to relevance is determined.

Findings

In the past, “little data, poor information” made it difficult for researchers to implement FHA. In this paper, the authors manage to deal with the problem of “poor information” and provide an approach to find the seriousness of aircraft failure.

Research limitations/implications

Due to the use of expert-evaluating methods, the classification of failures is still a little subjective and can be improved in this area. In the future, the method can be improved from the perspective of combining FMEA to analyze more complex indicators or using multisource heterogeneous solutions to solve fuzzy numbers, probabilities, gray numbers and indicators that cannot be assigned.

Practical implications

The paper uses FHA to divide the failure state and establishes a gray evaluation model of the aircraft failure state classification to verify the relevant method. Some aircraft safety design requirements are used to check the safety hazards of the aircraft during the design process, and to provide rational recommendations for the functional design of the aircraft.

Social implications

Improving the safety of aircraft is undoubtedly of great practical significance and has become a top priority in the development of the civil aviation industry. In this paper, the FHA method and the failure state of the aircraft are studied. The original FHA method is innovated by using the gray system theory applicable to the poor information state. Therefore, to some extent, this study has significance for improving the safety of civil aircraft flight, ensuring people’s travel safety and enhancing the society’s trust in civil aviation.

Originality/value

The main innovation of this paper is integrating the FHA method and the gray system theory. This study calculates the comprehensive relation degree of each failure under different flight stages, and uses FHA to divide the failure state, and finally establishes a gray evaluation model of the aircraft failure state classification to analyze the different conditions of the landing gear brake system, so that it improves the present situation, and the problem with the character of “little data, poor information” can be addressed better.

Abstract

Purpose

This paper aims to reframe the whistleblowing process by examining the individual and situational factors that have been overlooked by prior studies. Ethical climate, public service motivation (PSM), organisation identification and psychological safety are inquired.

Design/methodology/approach

The present study sample was drawn from a population of Indonesian local governments located in east Java, Indonesia. Particularly, self-administered questionnaires were hand-distributed to the employees in the four local governments. Of 2,169 questionnaires distributed to the employees, 1,687 questionnaires were returned to the researcher. However, the researcher removed 33 returned questionnaires because of poor data quality, such as incomplete answers. Thus, only 1,654 questionnaires were analysed in this study.

Findings

The findings support the idea of an ethical climate that can encourage the individual to blow the whistle. However, its effect is indirect. The predictive power of ethical climate on the individual’s whistleblowing intentions depends on the meditating roles of PSM, psychological safety and organisation identification. Interestingly, the mediating effects of PSM, psychological safety and organisation identification are extremely acknowledged when individuals have an opportunity to choose internal or external disclosures.

Originality/value

This study produces a different approach to understanding people’s intentions to report any wrongdoings. This study is dissimilar from prior studies in terms of the theoretical paradigm and research design. Previous studies mostly used students as their experiments. In contrast, the current study recruited employees who work in local governments. This situation fundamentally affects the understanding of the impact of an ethical climate on the individual intention to blow the whistle.

Abstract

Purpose

The purpose of this paper is to provide an introduction to the special issue on public service motivation (PSM) and human resource management (HRM). The authors analyse and review how the literatures on HRM and PSM relate to each other.

Design/methodology/approach

The paper combines two complementary studies: a bibliometric analysis of the interrelationships between the two literatures and a meta-analysis of the impact of HR practices on PSM.

Findings

Although HRM is among the core subject categories to which the literature on PSM refers, the pre-eminence of HR topics self-reported by PSM researchers indicates large room for further transfer. Intrinsic HR practices show positive and significant effects on PSM, while no such association was found for extrinsic HR practices.

Originality/value

The editorial is a complement to a recent bibliometric review of PSM research, focusing more particularly on the interrelationships with HRM and applying hitherto unused techniques. It is also the first meta-analysis of the association between HR practices and PSM.

Abstract

Purpose

This study aims to examine the interrelationship between the employee public service motivations (PSM), organisational corporate social responsibility (CSR) objectives and employee organisational commitment amongst accounts department staff in public service organisations.

Design/methodology/approach

Survey data is taken from tax accountants and accounts administration staff (n = 285) across seven South Korean state-owned enterprises involved in the provision of various public services (utilities, infrastructure, energy and housing). Structural equation modeling techniques are used to conduct mediation and moderated-mediation analysis.

Findings

Results show that both employee PSM and organisational CSR are significant in determining organisational commitment, especially where they result in value congruence. The authors also find that perceived levels of internal and external CSR are significant in moderating the impact of different dimensions of PSM.

Practical implications

As accounting in public service organisations faces growing professional and commercial demands to address stakeholder needs, the need for organisations to retain accounts staff with the necessary motivations is vital. The findings highlight the importance of value congruence in achieving long-term employee organisational commitment and the need for the CSR objectives of organisations to take account of both external and internal stakeholders.

Originality/value

Little research has examined the relationship between PSM and organisational commitment amongst accounting staff in the quasi-public/private state-owned enterprise sector. This despite the level of organisational (e.g. introduction of new public management approach) and professional change (e.g. regulatory changes) experienced over the past two decades and the importance of the sector in public service provision.

Abstract

Purpose

The purpose of this paper is to statistically test if the public service motivation (PSM) measure operates in the same way across the public and private sectors of a municipal district in China. It also contrasts the relationship between PSM and workplace outcomes across sectors and employee age groups.

Design/methodology/approach

Survey data from independent samples of public (n=220) and private (n=230) sector employees in the Changsha Municipal District of China is used. The analysis tests for invariance across groups, before comparing mean values and regression weights.

Findings

Only in respect of one PSM dimension do findings show a significant higher mean in the public sector. No significant difference is found on the impact of PSM on employee performance across sectors, while it is in the private sector that PSM has the greater impact on intention to leave. Findings also show no marked impact of age upon outcomes.

Research limitations/implications

This study provides an initial set of results and further research will need to be undertaken to verify them. The limited sample size and narrow geographical focus, although in line with similar studies on China, means the ability to draw generalisations is limited. The reliance on self-reported measures means issues with common method bias cannot be ignored. Measures were taken during data collection to minimise issues of bias and a set of post-hoc test results are provided.

Practical implications

The recruitment of employees with higher levels of PSM can be expected to play a role in achieving better outcomes, regardless of sector and age profile.

Originality/value

The PSM measure has been applied by researchers across various economic sectors. This paper is one of the first to statistically test if the concept and its measure operates in the same way across sectors. The paper contributes to the on-going debate on PSM in the context of China and its relationship with a number of key output variables. Finally, the paper contributes to the emerging debate on changing workforce demographics and their role in shaping outcomes.
