Abstract

Purpose

The purpose of this study is to explore a signal processing method to improve the angular rate accuracy of micro-electro-mechanical system (MEMS) gyroscope by combining numerous gyroscopes.

Design/methodology/approach

To improve the dynamic performance of the signal processing method, the interacting multiple model (IMM) can be applied to the fusion of gyroscope array. However, the standard IMM has constant Markov parameter, which may reduce the model switching speed. To overcome this problem, an adaptive IMM filter is developed based on the kurtosis of the gyroscope output, in which the transition probabilities are adjusted online by utilizing the dynamic information of the rate signal.

Findings

The experimental results indicate that the precision of the gyroscope array composed of six gyroscopes increases significantly and the kurtosis-based adaptive Markov parameter IMM filter (K-IMM) performs better than the baseline methods, especially under dynamic conditions. These experiments prove the validity of the proposed fusion method.

Practical implications

The proposed method can improve the accuracy of MEMS gyroscopes without breakthrough on hardware, which is necessary to extend their utility while not restricting the overwhelming advantages.

Original/value

A K-IMM algorithm is proposed in this paper, which is used to improve the angular rate accuracy of MEMS gyroscope by combining numerous gyroscopes.

Abstract

Purpose

By analyzing the mechanisms by which rural infrastructure resilience (RIR) impacted population loss in Longxi County, this study proposes measures to improve RIR, which provides a practical reference for realizing China's rural revitalization strategy, besides providing ideas for alleviating population loss in similar regions around the world.

Design/methodology/approach

This study considered 213 administrative villages in Longxi County in the Longzhong loess hilly region as the evaluation unit. Based on the construction of a multidimensional RIR evaluation system, the spatial spillover effect of RIR on population loss was determined using the spatial Durbin model (SDM).

Findings

The average resilience of each subsystem of rural infrastructure in Longxi County was low, and there were large differences in the spatial distribution. The mean RIR index value was 0.2258, with obvious spatial directivity and agglomeration characteristics. The population loss index of Longxi County had a value of 0.1759, with 26.29 of villages having a high loss level. The population loss was relatively serious and was correlated with the spatial distribution of RIR. The villages with larger RIR index values had lower population loss. The RIR had a significant spatial spillover effect on population loss. Productive infrastructure resilience and living infrastructure resilience (LIR) had negative spillover effects on population loss, and social service infrastructure resilience (SSIR) had a positive spillover effect on population loss.

Originality/value

By analyzing the mechanisms by which RIR impacted on population loss in Longxi County, this study proposes measures to improve RIR, which provides a practical reference for realizing China's rural revitalization strategy, besides providing ideas for alleviating population loss in similar regions around the world.

Abstract

Purpose

The Belt and Road Initiative (BRI) is the most comprehensive and substantial international cooperation platform, creating a new market influenced by economic and political factors. In this paper, the authors aim to examine whether and how the BRI impacts the Chinese enterprises' corporate environmental responsibility (CER).

Design/methodology/approach

Based on China's listed firms' database from 2011 to 2018, the authors use the PSM-DID method, an econometrics method combined with propensity score matching (PSM) and difference-in-differences (DID), to conduct causal inference between the BRI and Chinese enterprises' CER and conduct a series of robustness analyses. Moreover, the authors explore the mechanisms underlying the main effect from both market and non-market perspectives.

Findings

The results suggest that the BRI significantly increases Chinese enterprises' CER. Further analyses show that market competition and government support are two possible mechanisms through which the BRI has an effect on the enterprises' CER.

Originality/value

The research study supplements existing work on the environmental effects of the BRI at a microlevel and adds to the literature on the drivers of CER. The findings offer valuable insights into governments and scholars by demonstrating that CER is a crucial tool for Chinese enterprises to gain a competitive advantage in the increasingly competitive markets along the BRI.

Abstract

Based on in-depth interviews with 64 women in 5 Japanese firms, this chapter examines how women workers interpret workplace sexual behaviors and interactions in different organizational contexts. The chapter explores the processes by which workplace sexual interactions, including harmful behaviors, are normalized and tolerated. It discusses three types of sexual workplace interactions in Japanese firms: (1) taking clients to hostess clubs, which women workers often see as “a part of their job”; (2) playing the hostess role at after-work drinking meetings, where a certain amount of touching and groping by men is seen as “joking around” or simply as behavior that is to be expected from men; and (3) repetitive or threatening sexual advances occurring during normal working hours, which are seen as harassment and cause women to take corrective action. The chapter confirms previous studies that have shown that women's interpretations of sexual behaviors can vary from enjoyable to harmful, depending on the organizational contexts. The chapter also argues that Japanese organizational culture, through its normalization of male dominance and female subordination, fosters and obscures harmful behaviors. Eradicating harmful sexual behaviors will require firms to reevaluate sexualized workplace customs and mitigate the large gender gap in the organizational hierarchy in Japanese firms.

Abstract

Purpose

The purpose of this paper is to investigate how CEO humility influences inter-firm collaboration (IFC) and the moderating roles of firm status (a firm's relative position in a social order) and environmental uncertainty on such an effect.

Design/methodology/approach

As the firms were nested in township clusters, the theoretical model was tested using hierarchical linear modeling to analyze a multisource and multilevel onsite survey from 254 firms in Chinese township clusters. CEO humility was measured using an 18-item scale reported by both the human resource managers and the financial managers. Besides using CEO self-reported ratings as the measurement of IFC, this study employed additional measurements to further validate the findings, including the IFC reported by the administrative managers and two alternative measures for IFC reported by both CEO and the administrative managers of each firm.

Findings

This study found that CEO humility is positively related to IFC (H1), and that this association is marginally more salient when firms have high status (H2) but less salient when firms face a high level of environmental uncertainty (H3).

Practical implications

Findings suggest that firms with humble CEOs may benefit from better inter-firm collaborative relationships, especially when firms have high status (i.e. possess many well-known trademarks), but not when they are in an uncertain environment.

Originality/value

Previous humility studies focused on the influence of leader humility on individual and team outcomes, but little attention has been paid to organizational outcomes. This research extends the implications of leader humility to inter-firm relationships. Moreover, this paper explores the boundary conditions of the influence of CEO humility, thus advancing the contextual understanding of leader humility.

This study aims to investigate how relationship conflict (RC) hinders green customer integration (GCI) and which strategy could be developed to alleviate the negative effect of RC.

Abstract

Purpose

This study aims to investigate how relationship conflict (RC) hinders green customer integration (GCI) and which strategy could be developed to alleviate the negative effect of RC.

Design/methodology/approach

The authors use a sample of 206 Chinese firms to examine hypothesized relationships drawing on social exchange theory and buyer-supplier relationship perspective. Methods including exploratory factor analysis and confirmatory factor analysis are used to assess reliability and validity. Hypotheses are tested using hierarchical regression analysis. Post hoc analysis is adopted to evaluate the robustness.

Findings

The results show that RC negatively relates to GCI. Normative commitment partially mediates the relationship between RC and GCI, while the mediating role of instrumental commitment is insignificant. In addition, coercive influence strategy positively moderates the RC-normative commitment and RC-GCI relationships.

Research limitations/implications

While this study clarifies the mechanism of how RC impedes GCI and how to address RC in buyer-supplier relationships, it could be more meaningful to extend the current research and figure out how to address RC in different supply chain relationships. Besides, it will make sense to conduct longitudinal studies and explore the dynamic nature of RC in supply chain relationships.

Practical implications

In practice, firms find it challenging to achieve GCI owing to the ubiquitous existence of RC. The findings reveal that RC detriments GCI partially through normative commitment, and the use of coercive influence strategy mitigates the detriments of RC. Thus, the authors provide solutions for firms to address RC for achieving GCI.

Originality/value

RC is unavoidable in organizational interactions. Prior studies have not revealed the processes through which RC relates to GCI. The authors bridge the gap by exploring the mediating role of organizational commitment and the moderating role of influence strategy, which offers a better understanding of how RC is associated with GCI, and add knowledge of addressing RC for achieving GCI.

Abstract

Purpose

Cylindrical components are common in industry assembly areas. It is necessary to obtain their precise positions and orientations for their assemblies. But some measurement approaches relying on measuring targets are not allowed, as they may not meet the efficiency requirement of on-line measurement or may cause surface damages to the components. Thus, this paper aims to provide a precise on-line non-target scanning method based on 3D vision.

Design/methodology/approach

First, a laser profile sensor is used to acquire point cloud of the side surface of the measured cylindrical component. Then a composite process is conducted to estimate the pose and position of the axis. Aiming at this purpose, two fitting approaches, i.e., axis fitting and generatrix fitting, are tried respectively to estimate the pose parameters from the point cloud.

Findings

The results of Monte Carlo simulations demonstrate that neither the axis fitting nor the generatrix fitting could solely obtain the needed accuracy and precisions roundly. Thus, a new synthesis method is presented. And the results of prototype experiments validate the excellent accuracy and precision of the synthesis method.

Originality/value

This proposed new synthesis method combines the advantages of both the above fitting methods and can be easily integrated into the assembly line to guide the automation assembly process of the cylindrical components precisely.

Abstract

Purpose

The aim of this work is to synthesize neopentyl glycol oligoesters based on adipic acid and rapeseed oil (NOAR) which may be used as the renewable and environmentally acceptable base fluids to replace mineral oils in the future.

Design/methodology/approach

Oligomeric intermediates were synthesized in the first esterification of neopentyl glycol with adipic acid and characterized by Gas Chromatography-Mass Spectrometer (GC-MS) to calculate the average oligomerisation degree. NOAR were synthesized in the second esterification of oligomeric intermediates with rapeseed oil fatty acid. The effects of average oligomerisation degree on the viscosity, viscosity index, pour point, oxidative stability and biodegradability of NOAR were investigated; the tribological properties and thermal stability of NOAR were evaluated by four-ball tribometer and TGA, respectively.

Findings

Results show that with the increase of average oligomerisation degree from 2.10 to 4.34, the viscosity of NOAR increased from 101.1 to 182.0 (mm2/s) at 40°C and 18.3 to 30.1 (mm2/s) at 100°, respectively, and their oxidation stability can be improved as well. The yields of NOAR were 83.3-89.4 per cent, and the evaluated properties were as follows: viscosity index of over 200, pour point of below −43°C, biodegradation rate of more than 96 per cent, maximum non-seizure load (PB value) of 784 N, wear scar diameters of 0.40 mm and thermal decomposition temperature of higher than 300°C.

Originality/value

This work provides a method to synthesize rapeseed oil-based oligoesters which can serve as the renewable and environmentally acceptable base fluids with tunable viscosity by controlling the oligomerisation degree of esterification.
