Thisstudy is investigating the effects of project quality, project risk and project governance on project performance. Moreover, this study investigatesthe moderation effect of project leadership on these relationships. Data is collected from 354 respondents of software houses and structural equation modeling (SEM) technique is utilized for data analysis. Results suggest that project quality, p...

The continuous ecological management of the Loess Plateau is known throughout the world for two strategies: the integrated soil conservation project that began in the 1970s, and the “Grain for Green” project that began in the 1990s. Six sub-catchments nested in the Beiluo River basin were selected to investigate streamflow regime variations during the two project periods. The annual streamflow ...

In this paper, we built an agent-based model to integrate and synthesize social science theories to inform online community design. As an example, we use the model to examine how various styles of moderating online conversations affect community performance. We compared three styles of moderation – no moderation, in which all members are exposed to all messages; community-level moderation, in w...

OBJECTIVE The concepts and associated analyses of mediation and moderation are important to the field of psychology. Although pediatric psychologists frequently incorporate mediation and moderation in their theories and empirical research, on few occasions have we integrated mediation and moderation. In this article, conceptual reasons for integrating mediation and moderation are offered. MET...

Resum Moderation in virtual communities should not be a private privilege. This paper proposes a method for participants in a social network to decide their own rules for accepting (or not) contents. With the norm argument map, participants are able to argue about norms and voice their opinions about other people?s arguments. This structure, equipped with a method to fuse all the data introduce...

The variance components models for gene-environment interaction proposed by Purcell in 2002 are widely used. In both the bivariate and the univariate parameterization of these models, the variance decomposition of trait T is a function of moderator M. We show that if M and T are correlated, and moderator M is correlated between twins as well, the univariate parameterization produces a considera...

The current study presents a conceptual framework for the moderation of the relationship between implicit and self-attributed motive congruency and psychological well-being. Consistent with this framework, we found evidence for such moderation effects for predicting life satisfaction in a secondary data analysis of a sample (N = 441) drawn from the Eugene-Springfield Community Sample longitudin...

In this paper, I explore conditions that contribute to a rare outcome in ethnic party systems: the election of parties with moderate positions on interethnic relations. More specifically, I investigate why voters of the small, impoverished, and ethnically fragmented states of Bosnia and Macedonia, which share the same electoral system, chose parties with divergent positions on interethnic relat...

We show that factor forecasting models deliver real-time gains over autoregressive models for US real activity variables during the recent period, but are less successful for nominal variables. The gains are largely due to the Financial Crisis period, and are primarily at the shortest (one quarter ahead) horizon. Excluding the preGreat Moderation years from the factor forecasting model estimati...
