Drawing on principles of social exchange and equity theory, the purpose of this paper is to examine the relationship between employee reports of leader-member exchange (LMX) and two types of organizational citizenship behavior (OCB): affiliative and change-oriented OCB. Further, equity sensitivity, a dispositional variable reflecting one’s tendency to “give” or “take” in their interpersonal interactions, was tested as a moderator of these effects.

Data were collected from a sample of 240 manufacturing employees in China and their respective supervisors. Multilevel analyses were conducted to test the hypothesized effects.

LMX was found to be positively associated with affiliative, but not change-oriented OCB. Equity sensitivity moderated these relationships, such that LMX was positively associated with both types of OCB when employees are benevolent, but not when they are entitled.

Given the different pattern of relationships that were observed between LMX and affiliative vs change-oriented OCB, the results suggest that LMX may differentially influence these two types of OCB. Future studies should continue to explore the role of dispositional traits in moderating the effects of LMX, including less desirable (“negative”) traits.

Very few studies have examined the role of dispositional variables in moderating the effects of LMX. Consistent with principles of the social exchange and equity theory, the results suggest that LMX will only be associated with OCB when employees are benevolent (i.e. they are “givers”), and not when they are entitled (i.e. they are “getters”).

The purpose of this paper is to suggest the solution of time-fractional Fornberg–Whitham and time-fractional Fokker–Planck equations by using a novel approach.

First, some basic properties of fractional derivatives are defined to construct a novel approach. Second, modified Laplace homotopy perturbation method (HPM) is constructed which yields to a direct approach. Third, two numerical examples are presented to show the accuracy of this derived method and graphically results showed that this method is very effective. Finally, convergence of HPM is proved strictly with detail.

It is not necessary to consider any type of assumptions and hypothesis for the development of this approach. Thus, the suggested method becomes very simple and a better approach for the solution of time-fractional differential equations.

Although many analytical methods for the solution of fractional partial differential equations are presented in the literature. This novel approach demonstrates that the proposed approach can be applied directly without any kind of assumptions.

This study aims to explore the role of international ambidexterity (IA) in improving the innovation capability of emerging market multinationals. In particular, the main purpose of this research is to study the relationship amongst digitalisation, IA and innovation performance (IP) amongst multinational enterprises in China’s healthcare industry.

The data for this investigation were collected from 134 listed companies in China’s healthcare industry during the study period. This study tested the hypotheses by constructing a two-way fixed-effects model.

The results show that both the balance dimension and the combined dimension of IA have significant positive effects on IP. Digitalisation not only has a direct positive effect on IP but also positively moderates the positive correlation between IA and IP.

Previous studies have not captured the relationship between ambidexterity, digitalisation and IP, and this study helps to fill in the gap and examine these associations in China’s healthcare industry. The results of this study provide valuable insights for healthcare industry managers to understand the role of ambidexterity and digitalisation in innovation in the context of internationalisation.

The purpose of the study reported in this paper is to synthesis curcumin, which was reported to possess broad pharmacological effects and excellent dyeing properties, via Claisen-Schmidt condensation reaction catalysed by an efficient and green solid base catalyst, KF/Al₂O₃.

A series of catalysts with different KF loadings and varying calcination temperatures had been prepared, characterised by Brunauer–Emmett–Taller surface area, temperature-programmed desorption with CO₂ using infrared spectroscopy, X-ray powder diffraction and X-ray photoelectron spectroscopy, and tested in the Claisen–Schmidt condensation reaction. The effects of different reaction parameters such as temperature, the amount of catalyst, reactant ratio and time on the synthesis of curcumin were examined. The possibility of recycling the catalyst was also investigated in detail. Moreover, the reaction mechanism and the role of KF/Al₂O₃ in the synthetic process were discussed.

The study provides an efficient and green solid base catalyst, KF/Al₂O₃, and 64.3 per cent yield of curcumin was obtained under the optimum reaction conditions. Experimental results indicate that the third reused catalyst could retain part of the catalytic activity, and the regenerated one could be reused with reasonable catalytic activity. Besides, K₃AlF₆ was proposed as the active site of the catalyst for the reaction by the analysis of the characterization results of KF/Al₂O₃.

KF/Al₂O₃ was found to be an efficient catalyst for catalytic synthesis of curcumin and could be easily recycled several times. This information may be useful for further research and practical applications of curcumin.

Based on theories of media richness and procedural justice, the authors aim to examine the influence of videoconferencing (VC) technology on applicant reactions and interviewer judgments in the employment interview, the most commonly used employee selection device.

MBA students participated in simulated VC and face-to-face (FTF) interviews. Applicant perceptions of procedural justice and interviewer characteristics were collected. Interviewers provided ratings of affect toward the applicant, perceived applicant competence, overall interview performance, as well as an overall hiring recommendation.

Applicants perceived VC interviews as offering less of a chance to perform and as yielding less selection information. They also viewed VC interviews as less job-related than FTF interviews and had significantly less favorable evaluations of their interviewer (on personableness, trustworthiness, competence, and physical appearance) in VC interviews. Finally, applicants in VC interviews received lower ratings of affect (likeability) and lower interview scores, and were less likely to be recommended for the position.

The authors' findings suggest that VC technology can adversely affect both applicant reactions and interviewer judgments. They propose several precautionary steps to help minimize the risks associated with conducting VC interviews.

The authors extend prior research concerning the use of VC interviews by directly assessing applicant perceptions of both procedural justice and of interviewer characteristics associated with the probability that job offers will be accepted. They also add to the literature in showing that VC interviews tend to result in less favorable evaluations of applicants than FTF interviews.

Virtual machines (VMs) are suggested by the providers of cloud services as the services for the users over the internet. The consolidation of VM is the tactic of the competent and smart utilization of resources from cloud data centers. Placement of a VM is one of the significant issues in cloud computing (CC). Physical machines in a cloud environment are aware of the way of the VM placement (VMP) as the mapping VMs. The basic target of placement of VM issue is to reduce the physical machines' items that are running or the hosts in cloud data centers. The VMP methods have an important role in the CC. However, there is no systematic and complete way to discuss and analyze the algorithms. The purpose of this paper is to present a systematic survey of VMP techniques. Also, the benefits and weaknesses connected with selected VMP techniques have been debated, and the significant issues of these techniques are addressed to develop the more efficient VMP technique for the future.

Because of the importance of VMP in the cloud environments, in this paper, the articles and important mechanisms in this domain have been investigated systematically. The VMP mechanisms have been categorized into two major groups, including static and dynamic mechanisms.

The results have indicated that an appropriate VMP has the capacity to decrease the resource consumption rate, energy consumption and carbon emission rate. VMP approaches in computing environment still need improvements in terms of reducing related overhead, consolidation of the cloud environment to become an extremely on-demand mechanism, balancing the load between physical machines, power consumption and refining performance.

This study aimed to be comprehensive, but there were some limitations. Some perfect work may be eliminated because of applying some filters to choose the original articles. Surveying all the papers on the topic of VMP is impossible, too. Nevertheless, the authors are trying to present a complete survey over the VMP.

The consequences of this research will be valuable for academicians, and it can provide good ideas for future research in this domain. By providing comparative information and analyzing the contemporary developments in this area, this research will directly support academics and working professionals for better knowing the growth in the VMP area.

The gathered information in this paper helps to inform the researchers with the state of the art in the VMP area. Totally, the VMP's principal intention, current challenges, open issues, strategies and mechanisms in cloud systems are summarized by explaining the answers.

The rapid transition of the Chinese economic system from centrally planned to market mechanisms created a new market structure and changed the ways in which business had been conducted in China. Among these changes is the transformation in the marketing environment, which has introduced fragmentation and uncertainty and increased the complexity of operations. This chapter discusses the effectiveness of five Belgian joint ventures in China's fragmented environment and demonstrates the contributions they have made in terms of knowledge transfer and organizational learning, particularly in terms of formulating and managing local marketing strategies.
