The purpose of this paper is to test the influence of managerial coaching on frontline employee customer orientation, sales orientation and performance in a Chinese context. Further to this first goal, the authors also aim to compare these results with those obtained with a sample of Canadian bank employees in order to understand to what extent differences between Eastern and Western cultures affect business practices and employee responses in both environments.

This paper replicates a study from 2014 that used a sample of Canadian financial advisors to test the impact of managerial coaching on customer orientation, sales orientation and performance. In this new study, 185 frontline employees from a large insurance company in Chongqing (China) answered a paper-and-pencil questionnaire in Mandarin providing information about the coaching received from their managers, their own customer and sales orientation, as well as performance. Data were analyzed using structural equation modeling in AMOS as well as multigroup confirmatory factor analysis to evaluate cross-cultural differences.

The authors found that for the Chinese respondents managerial coaching is positively related to employee performance both directly and through the mediation effect of customer orientation. The authors found no support for the mediation of sales orientation between coaching and performance. These results suggest that managerial coaching might be a good strategy to promote relational behaviors in frontline employees, but not to reduce manipulative behaviors. The authors also found that these results are statistically equivalent for Chinese and Canadian respondents, suggesting that cultural differences are less prevalent than expected in this business sector.

The study makes several contributions to research. First, it suggests that managerial coaching can help employees develop their customer orientation–a central construct for commercial organizations working under a relational marketing approach. Second, it presents one of the first studies that evaluate the efficiency of managerial coaching in an Eastern country. And finally, results underline the equivalence of results for Eastern (China) and Western (Canada) respondents suggesting that in a global environment (like the financial industry) the business logic guiding the development of good customer relationships and employee customer-oriented behaviors prevails over potential cultural differences and makes leader and employee behaviors more similar and comparable across different regions in the world.

First, the use of managerial coaching seems to increase frontline employee relational behaviors, like customer orientation. Accordingly, managerial coaching seems to be a link that can help financial institutions bridge the formulation of a marketing relational strategy in the boardroom and the implementation of such a strategy at the customer interface between frontline employees and customers. Second, given the equivalence of results between the Canadian and the Chinese sample, it seems that the similarities between business models and business logics within the financial services sector are more important—and supersede—the potential cross-cultural differences between Eastern and Western countries.

The study makes a contribution to the limited literature on the use of managerial coaching in financial institutions to increase frontline employee relational behaviors. At the same time, it presents one of the few cross-cultural studies comparing results obtained from Chinese and Canadian respondents.

Radial vibration of horizontal centrifugal pump has a close association with radial exciting forces. The purpose of this paper is to analyze the unsteady radial force in multistage centrifugal pump with double volute in detail and investigate the relevance of static pressure, radial force and radial vibration.

The unsteady numerical simulation with realizable k-ε turbulence model was carried out for a multistage centrifugal pump with double volute using computational fluid dynamics codes Fluent. The performance tests were conducted by use of a closed loop system and performance curves from numerical simulation agree with that of experiment. Vibration tests were carried out by vibration probes instrumented on the bearing cover of pump near no-driven end. Fast Fourier transform was used to obtain the frequency components of radial forces on the impellers from numerical simulation, which are compared with ones of radial vibration from experiment in Y and Z direction. And the static pressure distributions in the impeller were analyzed under different flow rates.

The symmetrical double volute can effectively balance radial forces. The maximum radial force and vibration velocity appear at 0.6 Q among the three flow rates 0.6 Q, Q and 1.2 Q. The frequencies corresponding to relatively large amplitude of vibration velocities and radial forces on the impellers in Y direction are blade passing frequency of the impellers. Blade passing frequency of first-stage impeller and shaft frequency are predominating in Z direction. It indicates that the radial vibration of centrifugal pump is closely related to the unsteady radial force.

The unsteady radial forces of the impeller in multistage centrifugal pump with double volute were comprehensively analyzed. The radial forces should be considered to balance during the design of multistage centrifugal pump.

This article aims to predict the rapid track geometry change in the short term with a higher detection frequency, and realize the monitoring and maintenance of the railway state.

Firstly, the ABA data needs to be filtered to remove the DC component to reduce the drift due to integration. Secondly, the quadratic integration in frequency domain for concern components of the vertical and lateral ABA needs to be done. Thirdly, the displacement in lateral of the wheelset to rail needs to be calculated. Then the track alignment irregularity needs to be calculated by the integration of lateral ABA and the lateral displacement of the wheelset to rail.

By comparing with a commercial track geometry measurement system, the high-speed railway application results in different conditions, after removal of the influence of LDWR, identified that the proposed method can produce a satisfactory result.

This article helps realize detection of track irregularity on operating vehicle, reduce equipment production, installation and maintenance costs and improve detection density.

This paper aims to examine the consistency between firms’ stakeholder-friendly responses to the COVID-19 pandemic and their environmental, social and governance (ESG) ratings. Consistent firms are those with high prior ESG ratings that actively support stakeholders during the COVID-19 crisis.

The authors use data from JUST Capital, which tracks Russell 1000 firms’ actions in response to the pandemic, to examine the relationship between pre-pandemic ESG ratings and their COVID responses towards employees, customers and communities. The authors also analyse the impact of firms’ consistency between pre-pandemic ESG ratings and stakeholder-friendly COVID responses on ESG ratings and stock returns.

This study finds that firms with higher pre-pandemic ESG ratings are more likely to support their stakeholders during the pandemic. The authors also find that firms with high ESG ratings before the pandemic experience a decline in their ESG ratings if they do not actively support their communities during the COVID-19 crisis, although insufficient employee/customer support does not impact their ESG ratings. Finally, the authors find that firms with higher pre-pandemic ESG ratings that continue to uphold their ESG commitments through community assistance during the pandemic achieve higher stock returns compared to inconsistent firms.

The results reveal gaps in how comprehensively ESG agencies assess firms’ crisis responses, highlighting areas for rating improvements. The findings contribute to sustainable development by revealing the importance of firms upholding their ESG commitments during crises to maintain stakeholder trust and drive long-term value creation.

The findings underscore the need for responsive, transparent ESG rating processes to support the integration of sustainability considerations into corporate practices and investment decisions, particularly during evolving societal expectations during crises.

To the best of the authors’ knowledge, this study is the first to investigate how pre-pandemic ESG ratings explain firms’ stakeholder-friendly responses during the COVID-19 pandemic and analyse the integration of these responses and pandemic risks into ESG ratings during the crisis.

Pavement is one of the main elements of the roads network. It is extremely essential to study and understand the factors affecting its performance and highlight the most important ones for decision-makers and pavement experts to consider during the design, construction and maintenance stages. The purpose of this paper was to identify the factors affecting pavement performance and rank them according to their importance using Analytic Hierarchy Process (AHP) for decision-makers and pavement experts to consider during the design, construction and maintenance stages.

A survey was developed considering 29 factors found in the literature that affect pavement performance. The survey was sent to pavement professionals in Qatar to rate their perception of factors affecting pavement performance to enhance roads' sustainability. 205 responses were collected and analyzed using AHP.

The findings indicate that the factor “unconsidered heavy vehicles volume” is the most critical factor that affects pavement performance. The second most critical factor affecting the pavement performance is the “low asphalt content” due to escalating binder aging, reducing fatigue life of the pavement and decreasing the durability of roads. The third and fourth factors are “poor mechanical and thermal properties” and “unexpected high traffic volume,” respectively. These two factors are strongly attached to the first and second factors since the traffic volume affects the pavement performance less but similar to the heavy vehicles and a mix with poor mechanical and thermal properties is related indirectly to the asphalt content in the mix.

The research provides help for decision-makers in the construction industry to improve the performance of pavements using a multi-criteria decision-making tool. This paper's outcome would help the pavement management professionals in the construction industry to improve pavement performance and management, increase the pavement's life cycle and reduce maintenance costs.

The purpose of this paper is to study the multi-objective optimization design method of high-power high-frequency magnetic-resonance air-core transformer (ACT).

First, this paper studies the interleaved winding technology, the process of modeling and simulation, the calculation method of high-frequency loss of Litz wire and the design of magnetic shielding in detail. Second, the multi-objective optimization design process of high-frequency magnetic-resonance ACT is established by parametric scanning method and orthogonal experiment method.

An ACT model of 2 kV/100 kW/81.34 kHz was designed. The efficiency, weight power density and volume power density are 99.61%, 21.6 kW/kg and 5.1 kW/kg, respectively. Finally, the multi-physical field coupling simulation method is used to calculate the port excitation voltages and currents and temperature field of ACT. The maximum temperature of the ACT is 95.5 °C, which meets the design requirements.

The above research provides guidance and basis for the optimization design of high-power high-frequency magnetic-resonance ACT.
