Abstract
This study examined the effectiveness of a 4.5-day service leadership program for students from Chinese universities using objective outcome evaluation. The participants were assessed before and after the program, with two post-test measurements (immediate assessment and assessment 12 days after the completion of class learning). At pretest and two posttest time points, the participants completed a questionnaire measuring positive youth development, service leadership qualities and beliefs, and life satisfaction. Results showed that students’ performance in both the immediate posttest and follow-up test was better than that in the pretest. Despite the limitations of the one-group pretest-posttest design, results suggest that the curricular-based service leadership program was effective to promote students’ positive youth development, service leadership qualities and beliefs, as well as life satisfaction, and the effectiveness maintained a short period after the class had ended. While the existing findings are promising, these findings should be replicated in the future.

Abstract
Purpose
A real-time production scheduling method for semiconductor back-end manufacturing process becomes increasingly important in industry 4.0. Semiconductor back-end manufacturing process is always accompanied by order splitting and merging; besides, in each stage of the process, there are always multiple machine groups that have different production capabilities and capacities. This paper studies a multi-agent based scheduling architecture for the radio frequency identification (RFID)-enabled semiconductor back-end shopfloor, which integrates not only manufacturing resources but also human factors.
Design/methodology/approach
The architecture includes a task management (TM) agent, a staff instruction (SI) agent, a task scheduling (TS) agent, an information management center (IMC), machine group (MG) agent and a production monitoring (PM) agent. Then, based on the architecture, the authors developed a scheduling method consisting of capability & capacity planning and machine configuration modules in the TS agent.
Findings
The authors used greedy policy to assign each order to the appropriate machine groups based on the real-time utilization ration of each MG in the capability & capacity (C&C) planning module, and used a partial swarm optimization (PSO) algorithm to schedule each splitting job to the identified machine based on the C&C planning results. At last, we conducted a case study to demonstrate the proposed multi-agent based real-time production scheduling models and methods.
Originality/value
This paper proposes a multi-agent based real-time scheduling framework for semiconductor back-end industry. A C&C planning and a machine configuration algorithm are developed, respectively. The paper provides a feasible solution for semiconductor back-end manufacturing process to realize real-time scheduling.

Abstract
Purpose
The paper aims to investigate the difference in total factor productivity (TFP) among those firms with and without outsourcing in a developing country like Vietnam. Also, it explores the effect of outsourcing activities on total factor productivity with a specified concentration on the Vietnamese small and medium-sized enterprises (SMEs).
Design/methodology/approach
The panel data set of SMEs used in this study was originated from biannual surveys conducted under the collaboration between educational organizations and government agencies: Stockholm School of Economics (SSE), Department of Economics – the University of Copenhagen, the Institution of Labor Studies and Social Affairs (ILSSA) in the Ministry of Labor, Invalids and Social Affairs (MOLISA). In this study, the model is developed based on the production function in accordance with the model of Girma and Görg (2004). The firms’ TFP is the difference between the actual and the predicted output as with the approach by Levinsohn and Petrin (2003).
Findings
This study finds out that firms with outsourcing have higher total factor productivity than those without outsourcing activities. In addition, the more firms spend on outsourcing, the higher total factor productivity they can gain. Outsourcing to SMEs in a developing country can significantly increase its TFP by means of either maintaining core competencies or searching external resources in conducting some internal activities.
Originality/value
Although outsourcing has been widely applied by large firms, the research studying its impact on productivity at firm level is limited. Especially, this study can shed light on the impact for the case of SMEs in a developing economy.

Abstract
Purpose
This study aims to use the ego depletion theory to examine the impact of hindrance stressors on knowledge sharing behaviors by investigating the mediating role of ego depletion and the moderating role of self-enhancing humor.
Design/methodology/approach
Data were obtained from a two-wave sample of 226 dyads, including employees in the manufacturing industry and their direct supervisors. The hypotheses were tested by hierarchical regression analyzes and Hayes’ PROCESS macro.
Findings
The results demonstrated that employees’ self-enhancing humor style could alleviate the impact of hindrance stressors on employees’ ego depletion state and buffer the negative indirect effect of hindrance stressors on employees’ knowledge-sharing behaviors.
Research limitations/implications
Although the authors collected mediator and dependent variables from different sources, this study used a cross-sectional research design, making it difficult to draw causal conclusions. Besides, hindrance stressors, ego depletion and self-enhancing humor style were all reported by employees.
Originality/value
Through the study, the authors highlight the important role of the self-control view in explaining proactive behavior in the workplace and a great awareness of the unforeseeable consequences of ego depletion for employees.

Abstract
Purpose
The paper aims to provide a comprehensive investigation of the relationship between corporate governance (CG) structure and firm performance in Chinese listed firms from 2001 to 2015. The authors’ motivation derives from the fact that the CG system in China is different from those in the US, the UK, Germany, Japan and other countries.
Design/methodology/approach
A large unbalanced sample, covering more than 22,700 observations in Chinese listed firms, was used to explore, by means of a system-generalized method-of-moments (GMM) estimator, the relationship between CG structure and firm performance to remove potential sources of endogeneity.
Findings
Results show that Chinese CG structure is endogenously determined by the CG mechanisms investigated: there is no relationship between board size (including independent directors) and firm performance; CEO duality has a significantly negative effect on firm performance; concentration of ownership has a significantly positive influence on firm performance; managerial ownership is negatively correlated with firm performance; state ownership has a significantly positive effect on firm performance; and a supervisory board is positively correlated with firm performance.
Practical implications
The findings provide policymakers and firm managers with useful empirical guidance concerning CG in China.
Originality/value
Few integrative studies have examined the impact of CG structure on firm performance in China. This study adds new empirical evidence that the relation between CG structure and performance in China is endogenous and dynamic when controlling for unobserved heterogeneity, simultaneity, and dynamic endogeneity.

Abstract
Purpose
The purpose of this paper is to examine the experiences of employees who are exposed to dysfunctional behaviors by their leaders in a healthcare organization.
Design/methodology/approach
This study employed a qualitative methodology drawing on 25 semi-structured interviews with administrative and clinical employees working in a healthcare setting operating in Riyadh, Saudi Arabia.
Findings
This study’s findings provide insights into dysfunctional leadership phenomena based on employees’ personal experiences with dysfunctional leaders. Dysfunctional leaders have several harmful behaviors, such as behaving in abusive ways, marginalizing others, engaging in favoritism, and degrading employees. This study also demonstrated that the leaders’ negative behavior directly influences employees to leave their jobs, contributes to feelings of alienation at work, reduces their commitment, and frequently creates serious psychological and physical problems. This study also discovered that over time the negative effects of a dysfunctional leader do not stop at employees; it also filters through to other areas such as the organizational environment and family life.
Originality/value
Dysfunctional leadership is under-studied within the context of the Middle Eastern region. Therefore, this study’s findings provide theoretical and practical implications. It provides information about employee experiences and how dysfunctional behavior influences individuals and, ultimately, organizational life. Furthermore, this study has value to practitioners by offering suggestions for organizational interventions for creating more effective policies and programs to support employees’ careers and well-being.

Abstract
Purpose
The operating wagon records were produced from distinct railway information systems, which resulted in the wagon routing record with the same oriental destination (OD) was different. This phenomenon has brought considerable difficulties to the railway wagon flow forecast. Some were because of poor data quality, which misled the actual prediction, while others were because of the existence of another actual wagon routings. This paper aims at finding all the wagon routing locus patterns from the history records, and thus puts forward an intelligent recognition method for the actual routing locus pattern of railway wagon flow based on SST algorithm.
Design/methodology/approach
Based on the big data of railway wagon flow records, the routing metadata model is constructed, and the historical data and real-time data are fused to improve the reliability of the path forecast results in the work of railway wagon flow forecast. Based on the division of spatial characteristics and the reduction of dimension in the distributary station, the improved Simhash algorithm is used to calculate the routing fingerprint. Combined with Squared Error Adjacency Matrix Clustering algorithm and Tarjan algorithm, the fingerprint similarity is calculated, the spatial characteristics are clustering and identified, the routing locus mode is formed and then the intelligent recognition of the actual wagon flow routing locus is realized.
Findings
This paper puts forward a more realistic method of railway wagon routing pattern recognition algorithm. The problem of traditional railway wagon routing planning is converted into the routing locus pattern recognition problem, and the wagon routing pattern of all OD streams is excavated from the historical data results. The analysis is carried out from three aspects: routing metadata, routing locus fingerprint and routing locus pattern. Then, the intelligent recognition SST-based algorithm of railway wagon routing locus pattern is proposed, which combines the history data and instant data to improve the reliability of the wagon routing selection result. Finally, railway wagon routing locus could be found out accurately, and the case study tests the validity of the algorithm.
Practical implications
Before the forecasting work of railway wagon flow, it needs to know how many kinds of wagon routing locus exist in a certain OD. Mining all the OD routing locus patterns from the railway wagon operating records is helpful to forecast the future routing combined with the wagon characteristics. The work of this paper is the basis of the railway wagon routing forecast.
Originality/value
As the basis of the railway wagon routing forecast, this research not only improves the accuracy and efficiency for the railway wagon routing forecast but also provides the further support of decision-making for the railway freight transportation organization.

The purpose of this paper is to conceptualize how past corporate social responsibility (CSR) affects the occurrence of organizational misconduct by the means of moral licensing.
Abstract
Purpose
The purpose of this paper is to conceptualize how past corporate social responsibility (CSR) affects the occurrence of organizational misconduct by the means of moral licensing.
Design/methodology/approach
To this end, the authors conduct a conceptual review and develop a framework illustrating how moral credits and moral credentials (moral licensing) may institutionalize irresponsibility and lead to subsequent misconduct.
Findings
The authors propose a conceptual framework that describes the relationship between past CSR and organizational misconduct by the means of moral licensing. Based on initial literature-based findings, this paper provides confirmatory evidence for the authors’ framework and illustrates that past CSR might be used as a moral licensing tool that eventually fosters the occurrence of organizational misconduct.
Research limitations/implications
The authors propose future researchers account for the moral licensing effect when examining the antecedents of misconduct and explore the potential moderators of this effect.
Practical implications
The authors recommend that organizations establish management control systems that specifically address the issue of moral licensing when evaluating CSR initiatives. The authors also propose that organizations should adhere to a consistent CSR strategy that potentially fosters the selection of moral leaders who are not prone to moral licensing.
Originality/value
To the best of the authors’ knowledge, this paper is the first to connect corporate social responsibility, moral licensing and organizational misconduct from a conceptual perspective.
