This study explored from both cognitive and affective perspectives the mechanism involved in the internal effect of leader perfectionism on employee innovative behavior. Our goal was to disentangle the possible differential effects. A set of 254 leader–subordinate dyads completed
a two-stage questionnaire, and the results revealed that leader perfectionism was negatively related to employee innovative behavior. Further, perceived control and emotional exhaustion played a chain mediating role in this association. By revealing the influence path of leader perfectionism
on employee innovative behavior, this study enriches the literature and has practical significance for improving the leadership effectiveness of perfectionistic leaders.

The multi-agent paradigm has become a useful tool in solving military problems. However, one of key challenges in multi-agent model for distributed warfare could be how to describe the microcosmic tactical warfare platforms actions. In this paper, a platform-level distributed warfare model based on multi-agent system framework is designed to tackle this challenge. The basic ideas include: Establishing multi-agent model by mapping from tactical warfare system's members, i.e., warfare platforms, to respective agents; performing task decomposition and task allocation by using task-tree decomposition method and improved contract net protocol model technique; and implementing simulation by presenting battlefield terrain environment analysis algorithm based on grid approach. The simulation demonstration results show that our model provides a feasible and effective approach to supporting the abstraction and representation of microcosmic tactical actions for complex warfare system.Defence Science Journal, 2012, 62(1), pp.180-186, DOI:http://dx.doi.org/10.14429/dsj.62.964

This article proposes an empirical test of whether aggregate economic behavior maps from the real to the virtual. Transaction data from a large commercial virtual world — the first such data set provided to outside researchers — is used to calculate metrics for production, consumption and money supply based on real-world definitions. Movements in these metrics over time were examined for consistency with common theories of macroeconomic change. The results indicated that virtual economic behavior follows real-world patterns. Moreover, a natural experiment occurred, in that a new version of the virtual world with the same rules came online during the study. The new world's macroeconomic aggregates quickly grew to be nearly exact replicas of those of the existing worlds, suggesting that `Code is Law': macroeconomic outcomes in a virtual world may be explained largely by design structure.

Health and wealth are important to international social work discussions. This article examines the relationship between wealth indexes and the outcome of diseases such as diabetes, asthma, and BMI irregularities. It examines a construct of virtual neighborhoods in urban and rural populations of women. The data are drawn from the NFHS-3 (2007) and applies a hierarchical logistic regression analysis. It is found that women in mid-level neighborhoods in rural areas and poor neighborhoods in urban areas are most at-risk for negative health outcomes. Thus, women's health outcomes and processes appear to be complicated due to poverty and neighborhood interaction.
