Abstract

Purpose

This paper aims to solve the problem of uncertain position and attitude between unstructured terrain robot and grasped target and insufficient control accuracy in extreme environment, a grasping mechanism based on attraction domain relationship is proposed, which can realize autonomous positioning, capturing and grasping of robot under low control accuracy.

Design/methodology/approach

The grasping mechanism was designed, taking inspiration from fishing behavior this mechanism introduces attraction domains and flexible-elastic structures through the active and passive ends to achieve automatic positioning and capture. After the capture is completed, the grasping mechanism connects the active end and the passive end, simultaneously relying on the gravity of the target object to achieve locking and release between the robot and the target object. This paper adopts theoretical, simulation and experimental verification methods to conduct theoretical and simulation analysis on the autonomous positioning and grasping process of the mechanism, and produces grasping experimental prototypes with different positions and postures.

Findings

The experiment shows that the gripping mechanism designed in this paper can achieve automatic positioning capture and gripping of large deviation situations under low control accuracy, with a displacement deviation of up to 10 mm (about 1/6 diameter of the end of the mechanism) and an angle deviation of up to 3°. The scientific research task in the extremely high altitude environment has finally been successfully accomplished.

Originality/value

Inspired by fishing behavior, this paper proposes a positioning, capturing and grasping mechanism. The attraction area built with permanent magnets, coupled with the flexible connection, enables precise capture under low control, while the grasping mechanism can also rely on gravity to self-lock and release.

Abstract

Purpose

To construct a scientific and reasonable indicator system, it is necessary to design a set of standardized indicator primary selection and optimization inspection process. The purpose of this paper is to provide theoretical guidance and reference standards for the indicator system design process, laying a solid foundation for the application of the indicator system, by systematically exploring the expert evaluation method to optimize the index system to enhance its credibility and reliability, to improve its resolution and accuracy and reduce its objectivity and randomness.

Design/methodology/approach

The paper is based on system theory and statistics, and it designs the main line of “relevant theoretical analysis – identification of indicators – expert assignment and quality inspection” to achieve the design and optimization of the indicator system. First, the theoretical basis analysis, relevant factor analysis and physical process description are used to clarify the comprehensive evaluation problem and the correlation mechanism. Second, the system structure analysis, hierarchical decomposition and indicator set identification are used to complete the initial establishment of the indicator system. Third, based on expert assignment method, such as Delphi assignments, statistical analysis, t-test and non-parametric test are used to complete the expert assignment quality diagnosis of a single index, the reliability and validity test is used to perform single-index assignment correction and consistency test is used for KENDALL coordination coefficient and F-test multi-indicator expert assignment quality diagnosis.

Findings

Compared with the traditional index system construction method, the optimization process used in the study standardizes the process of index establishment, reduces subjectivity and randomness, and enhances objectivity and scientificity.

Originality/value

The innovation point and value of the paper are embodied in three aspects. First, the system design process of the combined indicator system, the multi-dimensional index screening and system optimization are carried out to ensure that the index system is scientific, reasonable and comprehensive. Second, the experts’ background is comprehensively evaluated. The objectivity and reliability of experts’ assignment are analyzed and improved on the basis of traditional methods. Third, aim at the quality of expert assignment, conduct t-test, non-parametric test of single index, and multi-optimal test of coordination and importance of multiple indicators, enhance experts the practicality of assignment and ensures the quality of expert assignment.

Abstract

Der Tourismus kann nur dort gedeihen, wo das Recht auf seine ungestörte Ausübung anerkannt wird. Das unbedingte Korrelat, nämlich die Pflicht, ein solches Recht umweltfreundlich, menschfreudig und vor allem gemässigt auszuben, ist davon nicht wegzudenken.

Abstract

Purpose

Materialism has been reported to be on the increase among health workers, a situation that can oppose the expected effect of remuneration on nurses’ satisfaction. The purpose of this study is to examine the effect of materialism on the remuneration–satisfaction relationship in an attempt to know if materialism is a negative behaviour that can counter efforts to increase nurses’ satisfaction through remuneration.

Design/methodology/approach

The quantitative (correlational) research technique was applied to test hypotheses of interest, with relevant confounding variables controlled for. The simple random sampling method was used to select a representative sample of 458 nurses. A self-reported questionnaire was used to gather data. The authors used structural equation modelling (SEM) to examine the factor structures of the measurement scales used in this study and to test hypotheses.

Findings

The study’s ultimate structural model produced a good fit at 5 per cent significance level [Chi-square = 11.654; p = 0.309]. After controlling for the relevant variables, remuneration makes a significant positive effect on the satisfaction of nurses, whereas materialism makes a negative effect on it. Materialism interacts with remuneration to make a significant negative effect on job satisfaction.

Originality/value

This study adds to the literature and adjusts for a unique set of relevant confounding variables in testing the primary relationships.

Abstract

Purpose

This study aims to assess the effect of religiosity on the job satisfaction of nurses in response to the paucity of studies that have investigated this relationship in a health care setting. The authors also tested the moderation impact of materialism on the religiosity–satisfaction nexus.

Design/methodology/approach

The quantitative (correlational) research technique was applied to test hypotheses of interest. The simple random sampling method was used to select a representative sample of 458 nurses. Confirmatory factor analysis (CFA) was used to examine the factor structures of relevant constructs and to test hypotheses. The study’s ultimate CFA model produced a good fit at 5 per cent significance level [Chi-square (χ2) = 19.121; p = 0.454].

Findings

Religiosity was found to make a positive effect on job satisfaction and a negative effect on materialism. Materialism makes a negative effect on job satisfaction. Religiosity and materialism makes a significant negative interaction effect on nurses’ satisfaction after controlling for job income.

Practical implications

It is therefore concluded that religiosity is a positive behaviour that contributes to the satisfaction of nurses, but materialism must be avoided or at least reduced to maximise this impact.

Originality/value

In this study, the authors demonstrate that the positive effect of religiousness on job satisfaction can be negatively moderated by materialism so that religiousness makes less impact on satisfaction owing to the negative influence of materialism on job satisfaction.

Abstract

Purpose

This paper reviews and synthesizes the extensive literature that investigates turnover in public accounting firms.

Design/methodology/approach

This paper initially identifies turnover studies by searching two commonly used business databases, ABI and Business Source. Subsequently, references in these studies are examined. Over 100 published studies of accounting firms are identified.

Findings

Prior turnover studies can be classified by the underlying theory: psychological attachment; role theory; mentoring; and organizational justice. Using these theories, prior research has examined a wide variety of issues such as the role of gender in turnover.

Practical implications

Turnover is a significant and long-term problem in accounting firms. Practitioners and researchers have long noted that firms lose the costs of training employees who leave the firm. Recently, many in the auditing field have recognized that employee turnover may reduce audit quality. This paper summarizes prior turnover research, which may provide guidance to future researchers and managers of accounting firms.

Originality/value

This study fills a void in the accounting literature, which is missing a comprehensive and up to date review of prior studies of turnover in accounting firms. Opportunities for future research are also explored. While much has been learned, some theoretical and methodological issues remain unresolved.

Abstract

Purpose

Drawing on the pay-for-performance (P4P) and job satisfaction literatures through an analysis of qualitative studies published on the topic, the purpose of this study is to investigate the effect of a P4P-based system on job satisfaction and dissatisfaction among health care workers.

Design/methodology/approach

A meta-synthesis of the qualitative literature was conducted to investigate health care workers' opinions, perceptions and behaviors and fully understand what processes generate job satisfaction or dissatisfaction under P4P systems.

Findings

The findings suggest that P4P systems impact the job (dis-)satisfaction of health care workers based on the institutional, organizational, geographic and cultural context of reference. Specifically, job satisfaction – and thus motivation, occupational well-being and work engagement – can occur when the context is supportive, whereas job dissatisfaction – and thus work stress and pressure, burnout and work-life balance issues and distraction – is generated in the case of unsupportive contexts. Moreover, the findings suggest a virtuous/vicious circle whereby job satisfaction leads to positive performance and further fuels job satisfaction, while conversely job dissatisfaction generates worse performance, and this further worsens worker satisfaction.

Originality/value

There is a lack of studies comparing and analyzing current evidence on the job (dis-)satisfaction of health care workers operating in different contexts based on the reward system. This is the first research to analyze a significant number of studies with reference to the relation between P4P and job (dis-)satisfaction, which are topics in need of further study and investigation in health care settings around the world.
