Abstract
Purpose
The purpose of this paper is to establish a dynamic model considering the actual operating conditions of the train and to study the dynamic performance and vibration characteristics of axle box bearings under different operating conditions.
Design/methodology/approach
In this paper, based on the internal contact characteristics of double-row tapered roller bearings, a dynamic model considering the actual operating conditions of the train is established. The correctness of the model is verified by the vibration test of the bearing. Comparative analysis was conducted on the effects of axial force, radial force and rotational speed on the angular velocity of the cage, slip rate and vibration acceleration level of the inner ring.
Findings
As the force increases, the slip rate of the cages on both sides decreases, and the vibration acceleration level of the inner ring increases. With the increase of rotational speed, the cage slip rate of the axle box bearing increases and the vibration acceleration level of the inner ring increases.
Originality/value
A dynamic model is established considering the actual operating conditions, and the dynamic performance and vibration characteristics of the axle box bearing under different operating conditions are analyzed by numerical method. The research content can provide reference for the parameter design of high-speed railway bearings.

Abstract
Purpose
The purpose of this paper is to establish a dynamic analysis model of composite cylindrical roller bearings, investigate the effects of different working conditions on the kinematic characteristics of composite bearings and compare the differences between them and solid roller bearings.
Design/methodology/approach
This paper establishes a dynamic analysis model for composite cylindrical roller bearings and proves the correctness of the established model by establishing dynamic vibration experiments and contact theory for composite roller bearings. Comparative analysis was conducted on the effects of coupling changes in rotational speed, load, number of rollers and filling ratio on parameters such as bearing static stiffness, contact stress and vibration acceleration.
Findings
The composite roller can enhance the bearing’s operational stability and minimize contact stress, but that a higher filling ratio is going to increase the bearing’s stiffness. The acceleration degree of bearing vibration, the load on the outer raceway nodes and the bearing stability all decrease as inner ring speed rises.
Originality/value
A dynamic calculation model of composite cylindrical roller bearings is established, and the influence of multiparameter coupling changes on bearing vibration and contact is studied, which lays a foundation for the structural improvement of the bearings.

Abstract
Purpose
The purpose of this paper is to examine the relationship of perceived transformative human resource (HR) practices and employee task performance. Drawing on evidence-based approach, the transformative HR practices intend to transform employees’ behavior to cope with organizational change. This study intends to answer how does the perceived transformative HR practices influence employees’ behavioral capability to enhance their task performance. This investigation proposes that the perceived transformative HR practices positively affect employees task performance, however, employee adaptivity mediates the relationship between them.
Design/methodology/approach
The authors used a random sample of 224 employees, from a large high-tech company in China, to test the hypotheses. Exploratory and confirmatory factor analyses were conducted to determine the perceived transformative HR practices in the context of a high-tech firm. The authors performed multiple linear regression analysis to examine the proposed model.
Findings
The results of this study indicate that the perceived transformative HR practices positively influence employee adaptivity and task performance. Furthermore, employee adaptivity mediates the relationship between the perceived transformative HR practices and employee task performance. Therefore, employee adaptivity illuminates and explains the underlying mechanism of how the perceived transformative HR practices lead to employee task performance.
Research limitations/implications
Data collected from single firm may limit the generalizability of the findings and cross-sectional research design may raise the concern of common method bias. Future studies should test and validate the operationalization of the perceived transformative HR practices in different research contexts and with larger sample size. Organizations should design and implement transformative HR practices to cope with change. Furthermore, organizational managers should encourage and facilitate employee adaptivity to achieve better performance.
Originality/value
This study contributes to change management and the HR literature by identifying and operationalizing the perceived transformative HR practices as a predictor of employee adaptivity and task performance. Through the underlying mechanism of employee adaptivity between the perceived transformative HR practices and employee task performance, this study provides a new perspective to look at the HR-performance relationship in the change process.

Abstract
This study was conducted to identify graduate students’ predominant study habit strengths and weaknesses as well as to examine empirically the relationship between specific study habits and library anxiety. Participants were 133 graduate students in the field of education at a university in the southeast of the USA. These individuals were administered the study habits inventory (SHI) and the library anxiety scale (LAS). Findings revealed that students’ responses to 62.9 per cent of the 63 study habit statements in the SHI were indicative of appropriate study habits. Study habit weaknesses were identified in the areas of note‐taking and reading skills. An all possible subsets multiple regression analysis led to the identification of eight specific study behaviours that predicted levels of library anxiety. These study habits explained 45.8 per cent of the variance in library anxiety, which, using Cohen’s criteria, represents a large effect size. Implications for library anxiety reduction as a study habits intervention are discussed.

Abstract
Research suggests that learning preference is an antecedent of statistics anxiety and research anxiety experienced by graduate students. Thus, the purpose of this study was to investigate the relationship between learning preferences and the following antecedents of library anxiety: “barriers with staff”, “affective barriers”, “comfort with the library”, “knowledge of the library”, and “mechanical barriers” among graduate students. Participants were 203 graduate students enrolled in a research methodology course. A series of setwise regression analyses revealed that the following 13 learning environmental preferences were related to one or more of these antecedents: noise preference, persistence orientation, responsibility, structure, peer orientation, authority orientation, multiple perceptual orientation, visual orientation, tactile orientation, kinesthetic orientation, morning preference, afternoon preference, and mobility preference. The implications of these findings are discussed.

Abstract
Purpose
The purpose of this paper is to explore the relationship between international diversification strategy and corporate social responsibility (CSR) for firms from emerging economies.
Design/methodology/approach
This paper is based on an empirical study of a sample of Chinese firms listed in Engineering News Record top contractors from 2010 to 2014. A moderated analysis is employed in order to test the hypotheses and examine how the scale and scope of international diversification affect CSR.
Findings
The empirical results show that degree of internationalization (DOI), as the scale, is positively related to firms’ CSR scores. Furthermore, two scopes, geographic diversification (GD) and project diversification (PD), have different effects on CSR scores. GD negatively moderates the relationship between DOI and CSR scores, while PD has a positive direct impact on CSR scores.
Research limitations/implications
This paper focusses on firms from emerging economies; therefore, the findings may not hold for firms from developed markets.
Practical implications
The results of this paper provide strategical advice regarding international business, for firms from emerging economies to meet the managerial challenges regarding CSR in global markets.
Originality/value
As the relationship between international diversification and financial performance has been thoroughly discussed in previous studies, this paper extends the literature on international diversification’s effects on CSR.

Abstract
Purpose
To reconcile the mixed findings on commitment-oriented human resource management (HRM) on employee job performance, this study tests whether commitment-oriented HRM has a threshold effect on employee job performance and when this threshold effect matters. The authors further tested the role of employees' age in the relationships.
Design/methodology/approach
The authors conducted a survey and collected data from 601 employees in 32 firms in China, and used a multilevel approach to test the hypothesis.
Findings
The results showed that the association between commitment-oriented HRM and employee job performance was J-shaped, meaning that commitment-oriented HRM was positively related to job performance when the degree of commitment-oriented HRM exceeded a threshold. Moreover, the authors found that employee age moderated this J-shape relationship. Specifically, the curvilinear relationship between development commitment-oriented HRM and job performance was stronger in younger employees. Contrary to our prediction, the results showed that younger employees reacted more strongly to improve job performance than older employees when maintenance commitment-oriented HRM exceeded a moderate degree.
Originality/value
The findings on the J-shape effect and moderating role of employee age on the J-shape provided critical insights into understanding the mixed results of the effect of HRM. Additionally, this study provided new insight in the linkage between HRM practices and employee outcomes.

Abstract
Purpose
The authors develop a theoretical framework of how foreign competition in a firm's home country jointly interacts with other environmental factors to influence the internationalization pace. This study moves beyond the debate on whether foreign competition promotes or inhibits the internationalization pace by unpacking the nature of pace across strategic and operational dimensions. By differentiating the internationalization paces of market scope and international commitment, the study results show that foreign competition has a positive effect on the former and a negative effect on the latter. This indicates that the determinants of different paces are conditional upon the different knowledge types among foreign competitors.
Design/methodology/approach
Using a panel data set of Chinese construction corporations over the period from 2009 to 2015, the authors extend previous research on the effect of home country environment on internationalization behavior in an emerging economy by examining the effects of the interplay between foreign competition in home country and industrial contexts. The authors also explore the moderating effect of subnational institutions on the relationship between foreign competition and internationalization pace. They use a Poisson model and a GEE model to examine the main effects and moderating effects involved.
Findings
The results indicate that industry dynamism strengthens the positive effect of foreign competition and the pace of market scope, while industry munificence weakens the negative effect of foreign competition and the pace of international commitment. The authors’ findings support the coexistence of “pushing” and “pulling” effects of environmental factors from a firm's home country. The authors extend the argument of “institutional escapism” by focusing on subnational institutions. They show that firms located in a region with a low level of marketization are more likely to respond by accelerating the pace of their international expansion to escape from their home country.
Originality/value
The authors’ findings have implications for practitioners and policymakers working with emerging market firms (EMFs). The authors suggest that local governments should consider building high-quality institutions that can reduce the possibility of investment opportunities escaping EMFs. The authors’ findings indicate that international knowledge from foreign competitors may also assist EMFs in understanding more about the cultural environment before entering host countries, although it cannot help them to resolve cultural uncertainty when operating in host countries. Hence, managers should carefully evaluate their competitiveness before they decide to engage in global competition at an accelerated rate.

Abstract
This study seeks to find an interactive effect between ethical leadership (EL) and corporate governance (CG) variables and investigate whether they would affect employee organizational citizenship behavior (EOCB) in a Malaysian organizational setting. The collected data from the 300 accounting/finance department employees were analyzed using Statistical Package for Social Sciences (SPSS) and Partial Least Square–Structural Equation Modeling (PLS-SEM; SmartPLS 3.0). Several primary results confirmed a coherent significant relationship between EL and ethical climate (EC), EL and EOCB, EL and CG, and CG and organizational success. Theoretically, it implies a more enhanced EOCB literature on how it can be infused in an organization. It also offers valuable knowledge by providing organizations with several insights concerning the improvement of EOCB, enabling the organization to achieve its desired success and, more importantly, how the findings could contribute directly and indirectly to emerging markets in terms of their industrial and financial performance.

Abstract
Purpose
The purpose of this paper is to examine the use of specific supply chain information technologies (IT) for e‐commerce, e‐procurement, and enterprise resource planning (ERP), when implementing lean practices to achieve mass customization (MC) performance. The study further investigates how these technologies may be deployed differently in product and service focused contexts. “Best practices” of high performing MC firms are also explored.
Design/methodology/approach
Survey method was employed to collect data from 711 firms in 23 countries. Exploratory factor analysis was employed to establish simple factor structure and construct validity. Hierarchical multiple regression was used to analyze relationships between lean practices, IT use, and MC performance in aggregated and bifurcated samples of product and service focused manufacturers. T‐tests were used to examine differences between the practices employed by high and low MC performers.
Findings
Findings suggest that lean practices can reasonably predict MC performance. In this context, of lean practices, e‐commerce and e‐procurement reasonably predict MC performance. ERP is not shown to predict MC performance. Results suggest that e‐commerce use is a better predictor of performance than e‐procurement or ERP for service focused manufacturers. E‐commerce and e‐procurement appear to be reasonable predictors of MC performance in product manufacturers, while ERP is not. “Best practices” related to lean practices, e‐commerce, e‐procurement, and ERP emerge among high MC performers.
Originality/value
This paper describes what is believed to be the first study to examine these three IT approaches in the context of lean practices and supply chain MC performance. This paper also contributes to the growing interest in differences among product and service focused manufacturing firms. Finally, specific “best practices” are provided to add value for practitioners.
