Abstract

Purpose

This study aims to investigate the impact of narcissistic leadership on employee voice behavior from the perspective of job stress, trust in leaders and traditionality in China.

Design/methodology/approach

The authors conducted a survey on 437 employees to assess their narcissistic leadership in Time 1. In Time 2, they measured their job stress, trust in leaders and traditionality. In Time 3, they assessed the voice behavior of these employees.

Findings

Narcissistic leadership correlates positively with employees’ job stress, which mediates between narcissistic leadership and employee voice behavior. Trust in leaders negatively moderates the correlation between job stress and employee voice behavior, as well as moderates the mediation effect of job stress on the correlation between narcissistic leadership and employee voice behavior. In addition, traditionality positively moderates the correlation between job stress and employee voice behavior, as well as moderates the mediation effect of job stress on the correlation between narcissistic leadership and employee voice behavior.

Originality/value

This study establishes the impact of narcissistic leadership on employee behavior from the perspective of job stress, trust in leaders and traditionality.

Abstract

Purpose

The purpose of this paper is to overcome the shortcomings of existing multivariate grey incidence models that cannot analyze the similarity of behavior matrixes.

Design/methodology/approach

First, the feasibility of using gradient to measure the similarity of continuous functions is analyzed theoretically and intuitively. Then, a grey incidence degree is constructed for multivariable continuous functions. The model employs the gradient to measure the local similarity, as incidence coefficient function, of two functions, and combines local similarity into global similarity, as grey incidence degree by double integral. Third, the gradient incidence degree model for behavior matrix is proposed by discretizing the continuous models. Furthermore, the properties and satisfaction of grey incidence atom of the proposed model are research, respectively. Finally, a financial case is studied to examine the validity of the model.

Findings

The proposed model satisfies properties of invariance under mean value transformation, multiple transformation and linear transformation, which proves it is a model constructed from similarity perspective. Meanwhile, the case study shows that proposed model performs effectively.

Practical implications

The method proposed in the paper could be used in financial multivariable time series clustering, personalized recommendation in e-commerce, etc., when the behavior matrixes need to be analyzed from trend similarity perspective.

Originality/value

It will promote the accuracy of multivariate grey incidence model.

Abstract

Purpose

When designing the electrode widths of the electrode-width-weighted (EWW) input interdigital transducers (IDTs) according to the envelope amplitudes of the wavelet function, the EWW wavelet transform processor (WTP) using surface acoustic wave (SAW) devices can be fabricated. The electrode widths have influence on the frequency characteristic of the EWW WTP using SAW devices. The purpose of this research is to solve the influence of the electrode width accuracy on the frequency characteristic of the EWW WTP using SAW devices.

Design/methodology/approach

In order to solve the influence of the electrode width accuracy on the frequency characteristics of the EWW WTP using SAW devices, the function between the electrode widths and the −3 dB bandwidth is derived. That the −3 dB bandwidth varies as the electrode widths is known according to this function so that the exposure time and the etching are presented as the two key problems.

Findings

Solutions to these problems are achieved in this study. As long as there is accurate exposure time, the precision IDTs (i.e. the precision electrode widths) will be obtained. The accuracy of the exposure time for the EWW WTP using SAW devices is ±1 per cent. Because the dry etching is a type of etching technology in gas medium, it can etch nanometer lines, even more fine lines, so that the dry etching is used in EWW WTP using SAW devices.

Originality/value

Research highlights solving the influence of the electrode width accuracy on the frequency characteristic for the EWW WTP using SAW devices; deriving the function between the electrode widths and the −3 dB bandwidth (it is known from this function that the −3 dB bandwidth varies as the electrode widths); and presenting the exposure time and the etching as two key problems.

Abstract

Let H be a connected subgraph of a connected graph G. The H-structure connectivity of the graph G, denoted by κ(G;H), is the minimum cardinality of a minimal set of subgraphs F={H1,H2,,Hm} in G, such that every HiF is isomorphic to H and removal of F from G will disconnect G. The H-substructure connectivity of the graph G, denoted by κs(G;H), is the minimum cardinality of a minimal set of subgraphs F={J1,J2,,Jm} in G, such that every JiF is a connected subgraph of H and removal of F from G will disconnect G. In this paper, we provide the H-structure and the H-substructure connectivity of the circulant graph Cir(n,Ω) where Ω={1,,k,nk,,n1},1kn2 and the hypercube Qn for some connected subgraphs H.

Abstract

Purpose

The purpose of this paper is to understand the attitude of patients towards the current medical service price and the effect of policy implementation, and explore the existing problems of the current medical service price policy in the region in order to provide a research basis for the dynamic adjustment mechanism of the medical service price.

Design/methodology/approach

Literature analysis and expert interviews are used to design the questionnaire of the dynamic adjustment of medical service price formation mechanism. A convenient sampling method is used to extract data of 600 patients from the five areas, namely Beijing, Tianjin, Hebei, Shandong and Liaoning, on-site to fill out the paper-based questionnaire and electronic questionnaire. The grey relational analysis is used to explore the difference in the attitudes of patients towards the price of the medical service. Combined with the research results and expert interview results, some improvement suggestions related to the current price policy of medical service in five areas are put forward.

Findings

The overall average score of respondents in the five areas, namely Beijing, Tianjin, Hebei, Shandong and Liaoning, is found to be 3.861. In terms of surgical operation fee and examination fee, the average score is higher than 4, i.e. 4.097 and 4.011, respectively, indicating “relatively high” nodes. According to grey relevancy sorting, the correlation between the health service price attitude and the overall score in the five regions is in the following order: Shandong > Tianjin > Beijing > Liaoning > Hebei.

Originality/value

In this study, patients’ attitude towards the current price of medical services in their local areas, Beijing, Tianjin, Hebei, Shandong and Liaoning, is investigated in order to explore the existing problems of medical service price reform and thus provide the basis for further improvement in the medical service price policy.

Abstract

Purpose

The purpose of this paper is to explore the rationality differences of cognition of non-technical medical services in different groups, and to provide countermeasures for improving non-technical medical services.

Design/methodology/approach

Literature analysis, expert interviews, questionnaire survey and frequency analysis were taken to reveal the influencing factors of non-technical medical services. Grey correlation methods were taken to compare the rationality differences of cognition of non-technical medical services by analysis influencing factors’ scores marked by different groups.

Findings

A total of 12 influencing factors of non-technical medical services were obtained, including “doctor’s working career”, “doctor’s strict implementation of medical treatment norms and medication guidelines”, “doctor’s service awareness”, etc. And rationality differences of cognition of non-technical medical services were confirmed as follows: the doctors’ cognition was more reasonable compared with patients; the women’s cognition was more reasonable compared with men; the lower aged groups’ cognition was more reasonable compared with higher aged groups; and people with doctoral degree had a less reasonable cognition compared with others.

Originality/value

The authors systematically discussed the cognition differences of non-technical medical services among different people, and provided some countermeasures reasonably.

Abstract

Purpose

To investigate the effects of hot oil carrying (HOC), the purpose of this paper is to present a new calculation method of oil film temperature which takes the effects into account and defines the factor of HOC.

Design/methodology/approach

Based on finite volume method, the paper studied the temperature characteristics in high speed and the condition of variable viscosity from the temperature field and flow field of the film, and the thermal rule of HOC is revealed. The theoretical values are in good agreement with the experimental results.

Findings

The results show that, for this structure of hydrostatic bearing, the phenomenon of HOC does not occur until the work speed is more than 10 r/min under any load condition. And it always happens in the total range of load, from 0 to 320 kN, when the speed is over 60 r/min. Moreover, the film temperature increases sharply, when the phenomenon happens in high speed, and the influence of the speed is greater than the effect of load on the temperature rise.

Originality/value

The results would help to increase the speed of CNC machine tools and the design on structure of the bearing in engineering practice.

Abstract

Purpose

Through a questionnaire survey, the purpose of this paper is to understand and analyse the cognitions of medical service price of medical workers in various regions of China, and discuss the policy suggestions on the price dynamic adjustment of medical service.

Design/methodology/approach

The authors conducted a questionnaire survey on the cognition of medical service price medical workers in various regions of China, and then the grey relational analysis theory is used to analyse the data obtained from the questionnaire survey.

Findings

The investigation and analysis shows some cognitions of hospital workers on the price of medical services in various regions in China, the authors analyse the results of grey relational analysis and come up with suggestions for relevant departments.

Research limitations/implications

Although a plenty of research on the current situation of medical service price cognition of China is discussed in the paper, it is not complete; thus, a large amount of information needs to be consulted further. The data obtained from the questionnaire are less used and the utilisation rate is lower, which may result in one-sided results and need further investigation.

Practical implications

Through the investigation and analysis, the authors can determine about the implementation of medical service prices in various parts of China from the perspective of hospital workers to a certain degree, and try to explore the relevant policy recommendations for the dynamic adjustment of medical service prices.

Social implications

The price of medical services refers to the fees for registration, diagnosis, inspection, surgery, nursing and medicine. In a narrow sense, the price of medical services refers to the standard of charge for medical services except drugs. This paper mainly refers to the narrow sense. As one of the important means and methods for the government to control the medical service market, medical service price is also an important basis for the economic source of medical institutions. The adjustment of medical service price is related to the interests of all aspects of society.

Originality/value

Medical service price is an important basis for the economic source of medical institutions, the adjustment of medical service price is related to the interests of all aspects of society and it is a hot issue of social concern. Through the investigation and analysis, the authors use grey relational analysis to know about the medical service prices in various parts of China from the perspective of hospital workers to a certain degree, and try to explore the relevant policy recommendations for the dynamic adjustment of medical service prices.
