This paper examines the impact of employee perceptions of organizational corporate social responsibility (CSR) practices on their job performance and organizational citizenship behavior (OCB). Hierarchical regression analysis on two-wave data from 184 supervisor/subordinate dyads from three organizations located in Zhejiang Province, South-East China, revealed that employee perceptions of CSR toward social and non-social stakeholders strongly influenced their OCB. However, employee perceptions of CSR toward employees, customers and government influenced neither their job performance nor OCB.

The aim of this research is to examine the efficiency of different aggregation algorithms to the forecasts obtained from individual neural network (NN) models in an ensemble. In this study an ensemble of 100 NN models are constructed with a heterogeneous architecture. The outputs from NN models are combined by three different aggregation algorithms. These aggregation algorithms comprise of a simple average, trimmed mean, and a Bayesian model averaging. These methods are utilized with certain modifications and are employed on the forecasts obtained from all individual NN models. The output of the aggregation algorithms is analyzed and compared with the individual NN models used in NN ensemble and with a Naive approach. Thirty-minutes interval electricity demand data from Australian Energy Market Operator (AEMO) and the New York Independent System Operator's web site (NYISO) are used in the empirical analysis. It is observed that the aggregation algorithm perform better than many of the individual NN models. In comparison with the Naive approach, the aggregation algorithms exhibit somewhat better forecasting performance.

 This study provides insight into how organizational climate can change and influence employee engagement using a structural, longitudinal, case study design. Quantitative and qualitative data were collected in two companies in the Philippines undergoing substantial change. An existing validated model of work practices and outcomes was used as a framework in collecting and analyzing the data. Results showed that both companies significantly changed aspects of their organizations associated with the quality of technology and facilities. However, only Company B showed significant changes in aspects associated with the involvement, development, and recognition of staff. With regard to the outcome of employee engagement, results showed that Company A did not report a significant change in employee engagement while Company B did report a significant change. Coding of qualitative comments supported the quantitative results. The findings support the argument that if organizations wish to improve employee engagement, a core requirement for organizational development is to improve the extent to which employees are involved, developed, and recognized within their organization.

The bulk of existing work on the statistical forecasting of air quality is based on either neural networks or linear regressions, which are both subject to important drawbacks. In particular, while neural networks are complicated and prone to in-sample overfitting, linear regressions are highly dependent on the specification of the regression function. The present paper shows how combining linear regression forecasts can be used to circumvent all of these problems. The usefulness of the proposed combination approach is verified using both Monte Carlo simulation and an extensive application to air quality in Bogota, one of the largest and most polluted cities in Latin America. © 2014 Elsevier Ltd.

Electrical load forecasting plays a vital role in order to achieve the concept of next generation power system such as smart grid, efficient energy management and better power system planning. As a result, high forecast accuracy is required for multiple time horizons that are associated with regulation, dispatching, scheduling and unit commitment of power grid. Artificial Intelligence (AI) based techniques are being developed and deployed worldwide in on Varity of applications, because of its superior capability to handle the complex input and output relationship. This paper provides the comprehensive and systematic literature review of Artificial Intelligence based short term load forecasting techniques. The major objective of this study is to review, identify, evaluate and analyze the performance of Artificial Intelligence (AI) based load forecast models and research gaps. The accuracy of ANN based forecast model is found to be dependent on number of parameters such as forecast model architecture, input combination, activation functions and training algorithm of the network and other exogenous variables affecting on forecast model inputs. Published literature presented in this paper show the potential of AI techniques for effective load forecasting in order to achieve the concept of smart grid and buildings.

Despite an increasing number of studies investigating the effects of mentoring on employee work outcomes, limited attention has been placed on the relationship between mentoring functions and turnover intentions. In this study, we examined the relationship between mentoring functions and turnover intentions, and the mediating role of perceived organizational support (POS) on this relationship. Using data collected from 176 employees in three Chinese banks, we found that POS partially mediated the relationship between mentoring functions and employees' turnover intentions.

© 2015 Springer Science+Business Media Dordrecht While the link between servant leadership and organizational citizenship behavior (OCB) has been established, the individual-level mechanisms underlying this relationship and its boundary conditions remain poorly understood. In this study, we investigate the salience of the mediating mechanisms of leader–member exchange (LMX) and psychological empowerment in explaining the process by which servant leaders elicit discretionary OCB among followers. We also examine the role of followers’ proactive personality in moderating the indirect effects of servant leadership on OCB through LMX and psychological empowerment. Analysis of survey data collected from 446 supervisor–subordinate dyads in a large Chinese state-owned enterprise suggests that while servant leadership is positively related to subordinate OCB through LMX, psychological empowerment does not explain any additional variance in OCB above that accounted for by LMX. Moderated mediation tests confirm the moderating effect of proactive personality through LMX. By providing a nuanced understanding of how and when servant leadership leads followers to go above and beyond their job role, our study assists organizations in deciding how to develop and utilize servant leaders in their organizations.

This study examines the relationship between employee perceptions of corporate social responsibility practices and their organizational commitment. Hierarchical regression analysis was utilized to analyze survey data on 280 employees from five export-oriented manufacturing firms in China. Employee perceptions of corporate social responsibility practices towards internal stakeholders were found to relate positively to their organizational commitment. In contrast, employee perceptions of corporate social responsibility practices to external stakeholders had a nonsignificant or marginally significant impact on organizational commitment. In addition, the collectivism and masculinity orientations of employees were found to moderate this relationship. These findings provide an insight into how corporate social responsibility practices may be utilized to motivate diverse groups of employees within China-based organizations. © 2013 Taylor & Francis.

This study examines the mediating effects of cognitive trust and affective trust on the relationship between supervisors' participative leadership behavior and subordinate work outcomes, using data obtained from 247 dyads in a manufacturing organization located in mainland China. Structural equation modeling revealed that while affective trust fully mediated the relationships between participative leadership of supervisor and subordinate job performance and organizational citizenship behavior, cognitive trust had non-significant effects. These findings underscore the importance of interpersonal interactions between the supervisor and subordinate for engendering subordinate work outcomes. They also lend support to the exchange (relationship)-based explanation as to how trust enhances the response of subordinates to the participative leadership behavior of their immediate supervisor, given that affective trust involves a process of social exchange between both parties over an extended period of time. © 2014 © 2014 Taylor & Francis.

This study investigates the relationship between extrinsic, intrinsic and social rewards, and the organizational commitment of 239 Chinese public sector employees. Hierarchical regression analysis revealed that although variables included to measure extrinsic and social rewards were strongly related to organizational commitment, variables included to measure intrinsic rewards had limited influence. These findings suggest that the antecedents of organizational commitment in the Chinese public sector are significantly different from those in the Chinese private sector and public sector organizations in the West. © 2013 © 2013 Taylor & Francis.

The present study examines whether participative leadership engenders organizational commitment amongst Chinese civil servants and analyses the mechanisms by which it transmits its effects. Confirmatory factor analysis and structural equation modelling revealed that there was a significant relationship between supervisor-level participative leadership and the affective and normative commitment of subordinates, but no relationship with continuance commitment. Affective trust was also identified as the mediator variable underlying the relationship between participative leadership and organizational commitment. We show that participative leadership of supervisors elicits higher levels of trust and leads subordinates to reciprocate through exhibiting higher levels of organizational commitment. Our study also reveals that Chinese civil servants who accept an unequal distribution of power between supervisors and subordinates typically exhibit lower levels of affective and normative commitment to the organization than those who do not. Our results provide greater support for the deepening of administrative reforms and the dissemination of participative leadership practices in China's new civil service system. © 2013 British Academy of Management.

In this study, we examine the nature of the relationship between ethical leadership and unethical pro-organizational behavior (UPB), defined as unethical behavior conducted by employees with the aim of benefiting their organization, and whether the strength of the relationship differs between subordinates experiencing high and low identification with supervisor. Based on three-wave survey data obtained from 239 public sector employees in China, we find that ethical leadership has an inverted u-shaped (curvilinear) relationship with UPB. As the level of ethical leadership increases from low to moderate, UPB increases; as the level of ethical leadership increases from moderate to high, UPB decreases. Further, we find that the strength of this inverted u-curve relationship differs between subordinates with high and low identification with supervisor. That is to say, the inverted u-shaped relationship between ethical leadership and UPB was stronger when subordinates experienced high levels of identification with supervisor. The theoretical and managerial implications of our findings for understanding how to manage UPB in an organizational context are discussed. © 2012 Springer Science+Business Media Dordrecht.

Purpose: The purpose of this study is to investigate the impact of perceived organizational support (POS), perceived supervisor support (PSS) and intra-organizational network resources on the turnover intentions of the Chinese employees of multinational enterprises. Design/methodology/approach: The study utilized structured equation modeling to analyze survey data from 437 Chinese employees of five multinational enterprises operating in the Chinese service sector. Findings: The study found that POS was positively related to affective organizational commitment, which in turn was negatively related to turnover intentions. A direct relationship was revealed between PSS and turnover intentions, as well as a mediated relationship through POS. In contrast, the relationship between intra-organizational network resources and turnover intentions was fully mediated through POS. Research limitations/implications: The cross sectional design is a limitation of the study. Another limitation regards the generalisability of the findings outside the specific research context. Future research should be extended to different geographical and organizational settings. Practical implications: In order to promote employee retention, multinational enterprises operating in China could start by carefully targeting visible support on offer to their employees. Improving supervisor support is a relatively inexpensive and practical measure compared to the costly alternatives such as improving employee compensation, training and career development. Organizations should also consider improving co-worker support schemes in the workplace which enable individuals to build up their network resources. Originality/value: The study provided evidence for both a direct relationship between PSS and turnover intentions and a mediated one via POS, confirming the generalisability of previous findings to the Chinese context. In addition it made an original contribution by establishing that POS fully, rather than partially mediated the relationship between intra-organizational network resources and turnover intentions. This suggests that Chinese employees attribute instrumental and expressive support from others in the organization as coming from the organization itself.

Purpose: The purpose of this study is to assess how the cultural value orientations of individual employees moderate their attitudinal responses to different categories of organizational rewards. Specifically, it seeks to examine how one dimension of traditionality, respect for authority, moderates the relationship between affective organizational commitment and three variables: pay satisfaction, autonomy and satisfaction with supervision. Design/methodology/approach: Hierarchical regression analysis was utilized to analyze survey data obtained from a sample of 290 employees of a major Chinese airline company. Findings: Employees high in traditionality were found to exhibit higher levels of affective commitment when autonomy and satisfaction with supervision was low. When autonomy and satisfaction with supervision was high employees low in traditionality exhibited higher levels of emotional attachment to the organization. Research limitations/implications: The cross-sectional design is an obvious limitation of the study. Another limitation relates to the generalizability of the study findings outside the context in which the research was undertaken. Social implications: Organizations should consider taking the cultural orientations of their workforce into account when developing appropriate human resource policies aimed at heightening employee commitment. This should enhance employee well-being, which is especially important in a global economy characterized by uncertainty and rapid change. Originality/value: This is the first study to examine how employees with different cultural value orientations respond to different categories of organizational rewards, in a predominantly traditional society.
