Abstract

Purpose

This study aims to propose the use of time series autoregressive integrated moving average (ARIMA) models to predict gas path performance in aero engines. The gas path is a critical component of an aero engine and its performance is essential for safe and efficient operation of the engine.

Design/methodology/approach

The study analyzes a data set of gas path performance parameters obtained from a fleet of aero engines. The data is preprocessed and then fitted to ARIMA models to predict the future values of the gas path performance parameters. The performance of the ARIMA models is evaluated using various statistical metrics such as mean absolute error, mean squared error and root mean squared error. The results show that the ARIMA models can accurately predict the gas path performance parameters in aero engines.

Findings

The proposed methodology can be used for real-time monitoring and controlling the gas path performance parameters in aero engines, which can improve the safety and efficiency of the engines. Both the Box-Ljung test and the residual analysis were used to demonstrate that the models for both time series were adequate.

Research limitations/implications

To determine whether or not the two series were stationary, the Augmented Dickey–Fuller unit root test was used in this study. The first-order ARIMA models were selected based on the observed autocorrelation function and partial autocorrelation function.

Originality/value

Further, the authors find that the trend of predicted values and original values are similar and the error between them is small.

This paper aims to investigate the innovation pathway of gerontechnological enterprises under the market-organization-technology (MOT) perspective through configuration analysis.

Abstract

Purpose

This paper aims to investigate the innovation pathway of gerontechnological enterprises under the market-organization-technology (MOT) perspective through configuration analysis.

Design/methodology/approach

Based on the analytical framework of technology, organization and market, this paper conducts configuration analysis on the cases of 55 elderly-friendly enterprises in China combined with fuzzy-set qualitative comparative analysis (fsQCA).

Findings

First, this study identifies the three first-level preconditions affecting innovation performance: organization's architectural innovation, technology adapting to aging and market environment attention on the innovation pathway of gerontechnological enterprises. These three first-level conditions include six sub-conditions. Second, this study investigates three innovation pathways by analyzing the configuration effects of preconditions: Configuration 1, technology-balanced type; Configuration 2, organization-market linkage type and Configuration, 3 balanced type. Third, there are differences in the distribution of different configuration types in subdivided industries. The technology-balanced configuration is mainly concentrated in design-driven innovative enterprises, the organization-market linkage configuration is mainly concentrated in medical auxiliary equipment enterprises and the balanced configuration is mainly concentrated in smart elderly care service platform enterprises empowered by digital technology. Fourth, there are differences in the innovation impact paths of the same configuration type. However, the essence lies in the high-level innovation performance formed by the coordinated evolution of technology, organization and market factors, reflecting the characteristics of the same goal through different routes.

Research limitations/implications

The authors' study generates new insights for innovation managers of gerontechnological enterprises about the innovation pathway.

Originality/value

This research enriches innovation management by integrating the linkage adaptation relationship among market, organization and technology factors; further research studies on the different configuration types suitable for different types of enterprises, as well as differentiated innovation pathways under the same configuration type, could contribute to the study on the innovation pathway under a premise of MOT.

Abstract

Purpose

This study aims to investigate the influences of perceived and preferred coaching behaviors and the discrepancy between them on job satisfaction, mediated by the quality of the relationship with the immediate supervisor and adaptive performance.

Design/methodology/approach

The research adopted a cross-sectional survey design. A total of 220 Korean employees, small-sized team members, were recruited from the automotive industry for the study. This research explored the relationship between perceived and preferred coaching behaviors using the Pearson correlation. Structural equation modeling was used to analyze the relationships among perceived and preferred managerial coaching behaviors, the discrepancy between them, the quality of the relationship with the immediate supervisor, adaptive performance and job satisfaction.

Findings

Perceived and preferred coaching behaviors exhibited a weak correlation. Perceived coaching behaviors indirectly influenced job satisfaction through the quality of the relationship with the immediate supervisor and adaptive performance. The discrepancy between perceived and preferred coaching behaviors directly and indirectly influenced job satisfaction via adaptive performance. However, all paths related to preferred coaching behaviors were found to be insignificant.

Research limitations/implications

Although the results of this research may be generalized to the Korean automotive industry, the findings highlight perceived and preferred coaching behaviors and the discrepancy between them as independent variables. The findings shed light on the influences of managerial coaching on the quality of the relationship with the immediate supervisor within Korean workplace cultures and how coaching behaviors contribute to triggering subordinates’ adaptive performance. In addition, the study provides how managerial coaching influences job satisfaction in the workplace.

Practical implications

Based on the findings, an organization should cultivate self-directed learning environments to enhance employees’ adaptive performance. The coaching training session should be added to the leadership development program for new managers. Team leaders need to consider their members’ preferences during managerial coaching.

Originality/value

The variables, such as preferred coaching variables and the discrepancy between perceived and preferred coaching behaviors, along with the research framework, represent a novelty in managerial coaching, as well as within the Korean context.

Abstract

Purpose

This paper aims to present an iterative path-following method with joint limits to solve the problem of large computation cost, movement exceeding joint limits and poor path-following accuracy for the path planning of hyper-redundant snake-like manipulator.

Design/methodology/approach

When a desired path is given, new configuration of the snake-like manipulator is obtained through a geometrical approach, then the joints are repositioned through iterations until all the rotation angles satisfy the imposed joint limits. Finally, a new arrangement is obtained through the analytic solution of the inverse kinematics of hyper-redundant manipulator. Finally, simulations and experiments are carried out to analyze the performance of the proposed path-following method.

Findings

Simulation results show that the average computation time is 0.1 ms per step for a hyper-redundant manipulator with 12 degrees of freedom, and the deviation in tip position can be kept below 0.02 mm. Experiments show that all the rotation angles are within joint limits.

Research limitations/implications

Currently , the manipulator is working in open-loop, the elasticity of the driving cable will cause positioning error. In future, close-loop control based on real-time attitude detection will be used in in combination with the path-following method to achieve high-precision trajectory tracking.

Originality/value

Through a series of iterative processes, the proposed method can make the manipulator approach the desired path as much as possible within the joint constraints with high precision and less computation time.

Abstract

Purpose

The purpose of the study is to measure the performance of Indian hospitals, both operationally and financially, by using hospital KPI's. The assessment is predominantly done by linking it to the existing Lean practices in Indian hospitals.

Design/methodology/approach

An empirical study based on cross-sectional survey of hospital managers and specialists in various private healthcare facilities across India was conducted to validate the proposed Lean framework. From an extensive literature survey, the authors identified quality, delivery, efficiency, accessibility and patient centeredness to be the main operational performance (OP) indicators for hospitals. Business or financial performance was measured based on parameters which are average revenue per occupied bed (ARPOB), earnings before interest, tax, depreciation and amortization (EBITDA) and operating revenue. Confirmatory Factor Analysis (CFA) was carried out using a specialized technique, called Structural Equation Modelling(SEM) and an explicit factor structure was hypothesized.

Findings

Management commitment towards Lean in hospitals is statistically proven to have impacted operational and financial performance. However, leanness in technology and business processes showed no statistical significance on either operational or financial performance parameters. Hospital stakeholders showed statistical significance on though it had no impact on the financial performance. Results obtained from the statistical analysis indicate a positive impact of hospital Lean practices on timely delivery of services and improved service quality. Efficiency, accessibility of services and patient centered behavior in hospital operations could not be statistically proven to have impacted the financial performance.

Social implications

Effectiveness of Lean management (LM) principles in improving hospital operations is largely dependent on patient centered behavior. Empowered employees who are trained to add value from a customer view point, make hospital operations safe and improved. Properly trained and communicated employees who are committed to quality improvements can make a positive impact on patients' quality of life and thus positively impact the society. The study lists ways to attain the required outcomes.

Originality/value

This paper is among the very few that has attempted to suggest ways to link implementation of Lean practices more effectively in Indian hospitals to improve hospital performance at operational and financial levels.

Abstract

Purpose

This study aims to develop a comprehensive green supplier governance (GSG) concept and explore whether specific GSG approaches (green supplier assessment, green supplier assistance and green strategic partnership with suppliers (GSPS)) bring environmental and economic performance. Moreover, this study aims to reveal a synergistic effect of three GSG approaches on performance improvement.

Design/methodology/approach

Using data collected from 200 Chinese manufacturing firms, regression analysis was employed to reveal the relationship between specific GSG approaches and firm performance. Further, cluster analysis was used to identify groupings of firms regarding implementation levels of three GSG approaches and compare the performance of the firm groups.

Findings

Green supplier assessment (GSA) can bring environmental performance, but GSA is not associated with economic performance. Green supplier assistance is positively associated with economic performance, while green supplier assistance cannot improve environmental performance. Only GSPS leads to improvement for both environmental and economic performance. Furthermore, firms with high implementation levels of GSA and GSPS (whether with high or low implementation levels of GSAS) can achieve the best environmental and financial performance.

Practical implications

This study provides implications for firms to more strategically and comprehensively implement GSG approaches, which can be more effective in bringing environmental and economic performance.

Originality/value

The authors' study extends the GSG concept with two approaches by subdividing the collaborative approach into green supplier assistance and GSPS based on the collaboration levels. This study also sheds light on how to improve firm performance by different GSG approaches and reveals a synergistic effect of three GSG approaches on performance.

Abstract

Purpose

This paper aims to investigate the influence of Islamic marketing ethics and convergence marketing on competitive advantage and bank performance.

Design/methodology/approach

This study is based on a survey of 204 Indonesian branch managers from the Islamic banking industry. Results were produced with the partial least square approach.

Findings

Results revealed that Islamic marketing ethics and convergence marketing have sufficient confidence to have significant influences on competitive advantage, producing a positive association with a competitive advantage. However, Islamic marketing ethics and convergence marketing did not influence bank performance directly. Competitive advantage positively mediated the relationship. Furthermore, organizational digital literacy did not moderate the relationship between convergence marketing and bank performance.

Research limitations/implications

This study contributes to the conceptualization of convergence marketing and the identification of its effects on competitive advantage and bank performance. The identification of convergence marketing in this dissertation contains dimensions of mobile, security, foreign currency, holistic and interactivity as different aspects from the steps of Islamic banks to digitize their services to the internet in a single application. The results also indicate that convergence marketing does not have a direct effect on bank performance but has an indirect effect through competitive advantage. Convergence marketing must first create a bank advantage over its competitors to have a good effect on bank performance.

Practical implications

This study offers many opportunities for Islamic bank marketers to improve performance. Many Islamic banks currently do not implement Islamic marketing ethics consistently and thoroughly. The results of this study encourage Islamic banks by showing that the more intensive and consistent they are in implementing Islamic marketing ethics, the better their competitive advantage and the higher the performance. This effort can be done in various ways, such as offering tariffs/ratios of services transparently to customers, not exaggerating the benefits of the products offered to distort customer expectations, building brands that can strengthen customer confidence in Islamic banks and only offering products and services with high-quality standards.

Limitation and future research

This study uses a sample of Islamic banking so that it is still limited to certain types of banks. Future research needs to conduct model testing in different contexts such as conventional banking. In addition, further research needs to use the capabilities or capabilities of bank IT as a moderator in the effect of convergence marketing on bank performance. Future research also needs to control for more variables and use a scale that is more complex than the binary scale (for example, the percentage of share ownership or territory in the scope of the province or district/city).

Originality/value

This research views the Islamic bank competitiveness through the lenses of Islamic ethical theory and convergence marketing theory.

This paper aims to examine the effect of R&D laboratories on the perceived performance of MNE subsidiaries during recession.

Abstract

Purpose

This paper aims to examine the effect of R&D laboratories on the perceived performance of MNE subsidiaries during recession.

Design/methodology/approach

Employing resource-based view and knowledge-based theory, the authors investigate a unique sample of 171 technologically heterogenous foreign MNE subsidiaries located in Greece over the period of recession 2009–2016. The sample subsidiaries operate different types of R&D laboratories.

Findings

The authors find that MNE subsidiaries with advanced R&D laboratories such as locally integrated laboratories (LILs) and internationally interdependent laboratories (IILs) perform better in recession than subsidiaries with support laboratories (SLs) or subsidiaries without R&D laboratories. Overall, the authors find an asymmetric performance contribution of R&D laboratories at subsidiary level.

Originality/value

The study provides useful insights into the environmentally derived “knowledge-based - performance” context, so filling an important research gap, since little is known about the performance impact of the input-side of technological activity at MNE subsidiary level, especially as regards R&D facilities/infrastructure. Based on the findings the authors identify important managerial implications.

Abstract

Purpose

Grounding on the goal-setting theory and flow theory, this study explored the mechanism underlying the association between transfer design (TD); identical elements and training transfer (TT). Specifically, the authors explored a moderated mediation process of trainer performance and motivation to improve work through learning (MTIWL) that has received less consideration in the TT literature.

Design/methodology/approach

Data were collected using the retro-perspective survey method. The first survey was administered offline (t1: the day when leadership intervention was completed. Subsequently, trainees were requested to participate in an online survey (t2: 12–14 weeks later). In all, 355 executives participated.

Findings

The results of structural equation modeling (SEM) analyses suggested that trainees’ MTIWL mediational impact between leadership intervention triggers (transfer design and identical elements), and TT was supported. In addition, the indirect impact of these variables on TT was found to be significant when the trainer had high performance than when it was low. This confirmed the trainer’s performance as a potential moderator in the TT process.

Practical implications

This study is limited to the exploration of leadership intervention variables on TT. The findings have implications for leadership professionals and scholars who use leadership intervention and motivation metrics to predict TT.

Originality/value

This study offers a moderated mediation mechanism for enhancing TT through leadership intervention triggers. The proposed conceptual model included MTIWL as mediator and trainer performance during leadership intervention as moderator.

Abstract

Purpose

This paper examines the mediation role of green innovation in the relationship between corporate social responsibility and environmental performance of manufacturing firms in Ghana.

Design/methodology/approach

The paper chose African emerging markets and surveyed managers from manufacturing firms. With 301 questionnaires qualified for this study’s final analyses, the authors adopt the multiple regression with mediation models to estimates the nexus among study variables.

Findings

Results evidence that both corporate social responsibility and green innovation has a positive and significant impact on environmental performance. Interestingly, the authors find that corporate social responsibility significantly improves environmental performance through green innovation indicating that firms could essentially build their dynamic resource and innovation capabilities in sustainability leading to enhanced environmental performance.

Research limitations/implications

This paper develops a dynamic resource-based view of firm environmental performance illustrating how firms use resources to build strategic capabilities for competitive advantage, which leads to improved environmental performance. The paper highlights the mediation role of green innovation on corporate social responsibility and environmental performance relationships.

Practical implications

This study's results provide significant insights to owners and managers of manufacturing companies to integrate corporate social responsibility and green innovation to ensure environmental performance and sustainability. Furthermore, policy makers should encourage green innovation when design sustainable development systems in the manufacturing industry.

Originality/value

The paper provides a valuable model showing how green innovation mediates corporate social responsibility to improve environmental performance and build competitive advantages considering both small, medium, and large manufacturing enterprises in emerging countries.
