Abstract

Purpose

Massively multiplayer online role-playing games (MMORPGs) create quasi-real social systems in which players can interact with one another, and quasi-real economic systems where players can consume and trade in-game items with virtual currency. The in-game currency price, an important indicator of a virtual economy, is highly contingent on players’ behavioral interaction in MMORPGs. The purpose of this paper is to adopt a network perspective to examine how topological characteristics of social networks in an MMORPG, namely, network externalities, density, and closure, would exert impacts on the in-game currency price.

Design/methodology/approach

Players’ behavioral data were collected from a popular MMORPG in China on a weekly basis for 52 weeks. With a time series analytical approach, the empirical model for the price function of in-game currency was estimated with vector autoregression.

Findings

The results show that the number of core avatars and network density are positively associated with in-game currency price, while network closure has a negative effect on in-game currency price. However, in-game currency price is found to have no significant relationship with the trade volume of the currency.

Originality/value

This study fills in an important research gap by investigating factors influencing the in-game currency price of MMORPGs from a network perspective, which contributes to the existing literature of network effects and advances our understanding about how players’ interaction will influence the dynamics of a virtual economy. The findings could offer useful insights for online game companies to better understand their players’ social interaction and consumption behavior.

Abstract

Purpose

The purpose of this paper is to reveal the influence of organizational identification (OI) on organizational citizenship behavior (OCB) directed toward organization (OCB-O) and OCB directed toward individuals (OCB-I), and explore the moderating effects of turnover intention (TI) and the differences of the moderating effects of supervisors’ ratings of leader–member exchange quality (LMX-L) and subordinates’ ratings of LMX quality (LMX-S) in the process.

Design/methodology/approach

Based on social exchange theory, this study took administrative staff of private small and medium enterprises in China as population. A paired-samples design was used, and 437 valid paired samples were collected finally. Data analyses were conducted by using structural equation modeling.

Findings

OI indicated a positive influence on both OCB-O and OCB-I. TI showed a negative moderating effect on the positive relationship between OI and OCB-I, but no significant moderating effect on the positive relationship between OI and OCB-O. LMX-L and LMX-S were not in one same direction and showed different moderating levels. LMX-L had no significant effects on the relationship between OI and OCB-O, nor did on the relationship between OI and OCB-I. On the other hand, LMX-S strengthened both the positive relationship between OI and OCB-O, and the positive relationship between OI and OCB-I.

Originality/value

This study explored the relationships from social exchange perspective, found that OCB-O and OCB-I had different formation mechanisms and should be explored as distinct variables, and confirmed that it was necessary to use the paired-samples design when studying dyadic phenomena.

Abstract

Purpose

This paper aims to reveal the current status of China university teachers’ learning content focus (LCF) and collaborative learning (CL) and empirically examine the influential effects LCF and CL play on individual pursuit of lifelong learning (LLL) by investigating the mediating role of individual psychological empowerment (PE).

Design/methodology/approach

Descriptive analysis and structural equation modeling (SEM), including exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and path analysis, are conducted.

Findings

The results of this study indicate significant direct impacts of LCF, CL and PE on university teachers’ LLL. LCF shares significant positive relationship with PE, validating the mediating role of PE between LCF and LLL. University teachers show their consciousness of learning required in professionalism and willingness to keep learning. However, the four major discrepancies: Lifelong Learning Process (LLLP) vs Lifelong Learning Behavior (LLLB), focus of professional promotion system vs that in LCF, lower levels in Self-determination and Impact (in PE) and less external partnerships, indicate the gaps between learning supports provided by university and policy designing in promoting LLL.

Originality/value

This study emphasizes the LLL ideology in professional development. Emphasis on university teachers’ learning within specific professional development contexts would encourage researchers to pay more attention to context-relevant factors enhancing LLL. And the four major discrepancies identified in this study deserve further investigations.

Abstract

Purpose

The purpose of this paper is to examine the effect of inventory leanness on productivity. In particular, the authors explore the moderating role of environmental complexity and the mediating role of risk taking.

Design/methodology/approach

In the mediated moderation analysis of the relationship among inventory leanness, risk taking, environmental complexity and productivity, the authors adopt the instrumental variable method to test the hypotheses based on data collected from 1,709 Chinese listed manufacturing firms.

Findings

The results show that there is an inverted U-shaped relationship between inventory leanness and productivity. The authors then demonstrate the role of risk taking in mediating this relationship. Furthermore, the authors find that environmental complexity not only negatively moderates the relationship between inventory leanness and productivity, but also negatively moderates the relationship between risk taking and productivity.

Practical implications

Managers should not be excessively pursuing inventory leanness improvements, so as not to damage the ability to increase productivity.

Originality/value

This paper may be the first study to empirically demonstrate the moderating effect of environmental complexity and the mediating effect of risk taking on the inverted U-shaped relationship between inventory leanness and productivity.

Abstract

Purpose

Water-lubricated bearings can significantly reduce the pollution to environment because the traditional oil lubricant is replaced by water in the bearings. The ultrahigh molecular weight polyethylene (UHMWPE) has proven to be effective and reliable for the manufacturing of water-lubricated bearings. However, limited work has been done to address the improvement of the tribological performance of the UHMWPE-based water-lubricated bearings using surface texture processing. This paper aims to investigate the effects of bar-grooved surface on the tribological performance improvement of UHMWPE-based water-lubricated bearings.

Design/methodology/approach

For the first time, the bar grooves were processed on the surfaces of UHMWPE-based water-lubricated bearings. The CBZ-1 friction and wear tester have been used to test the wear and friction performance of the bearing samples. The LI laser interference surface contour graph and the digital microscope have been used to measure the surface morphology of the specimens. The tribological characteristics of the tested bearings were analyzed.

Findings

With bar grooves added on the surfaces of the specimens, the friction coefficient of the specimens were lower than that of the specimens without surface texture processing; the wear quantity of the two kinds of specimens were almost the same; by using the LI laser interference surface contour graph and the digital microscope to measure the surface morphology of the specimens, the furrows of the specimens with bar grooves were narrower and shallower than that of the specimens without bar grooves.

Practical implications

The paper implicates that the surface texture processing using bar grooves can reduce the friction coefficient and prolong the service life of the water-lubricated bearings in practical applications.

Originality/value

This paper fulfills an identified need to provide important theoretical and experimental support to the design of water-lubricated bearings in practical applications.
