When does community participation enhance the performance of open source software companies?

This study examined how participation in open innovation communities influences the innovative and financial performance of firms commercializing open source software. Using an original dataset of open source companies in the Netherlands, I found that the community participation–performance relationship is curvilinear. In addition, results indicate that extensive technical participation in open source projects is more strongly related to performance for firms that also engage in social (“offline”) community activities, for companies of larger size, and for firms with high R&D intensities. Overall, this research refines our understanding of the boundary conditions under which engagement in community-based innovation yields private returns to commercial actors.     

Monetary donations to an open source software platform

Online open source software platforms, such as Sourceforge.net, play a vital role in creating an ecosystem that enables the creation and growth of open source projects. However, there is little research exploring the interactions between open source stakeholders and the platform. We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives—voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study 1 investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels.     

The integration of open access journals in the scholarly communication system: Three science fields

The greatest number of open access journals (OAJs) is found in the sciences and their influence is growing. However, there are only a few studies on the acceptance and thereby integration of these OAJs in the scholarly communication system. Even fewer studies provide insight into the differences across disciplines. This study is an analysis of the citing behaviour in journals within three science fields: biology, mathematics, and pharmacy and pharmacology. It is a statistical analysis of OAJs as well as non-OAJs including both the citing and cited side of the journal to journal citations. The multivariate linear regression reveals many similarities in citing behaviour across fields and media. But it also points to great differences in the integration of OAJs. The integration of OAJs in the scholarly communication system varies considerably across fields. The implications for bibliometric research are discussed.

At the foundations of information justice

Is there such a thing as information justice? In this paper, I argue that the current state of the information economy, particularly as it regards information and computing technology (ICT), is unjust, conferring power disproportionately on the information-wealthy at great expense to the information-poor. As ICT becomes the primary method for accessing and manipulating information, it ought to be treated as a foundational layer of the information economy. I argue that by maximizing the liberties (freedom to use, freedom to distribute, freedom to modify, and so on) associated with certain computer software, an incentives-rich and stable environment can be established in ICT that will foster development of the information economy among the information poor. I suggest that the now-mature Free and Open Source Software paradigm, which has already produced widely-used enterprise-class applications, can be harnessed in support of these ends.     

Social networks and coordination performance of distributed software development teams

In this study, we explore the coordination performance of the geographically distributed software development teams by exploring OSS (Open Source Software) development dataset available through SourceForge.com. OSS team structures have traditionally been geographically dispersed and therefore, the coordination of post release activities such as testing efforts have been carried out by means of communication via electronic forms, such as email or message boards and forums. In our current communication-enriched environment, best practices for coordination are adopted by all software projects yet some still fail to achieve their target performance. Does team structure have any bearing on the performance outcome of the project? How does the communication between teams and their external parties affect ultimate success or failure of projects? We seek to answer above questions by applying existing theories and analytical methods from social networks for exploring the coordination performance of defect management activities found in OSS projects. We propose social networks based theoretical model for exploring distributed coordination structure and apply that for the case of OSS defect management process for exploring the structural properties, which induce the greatest coordination performance. The outcome of our suggest that there is correlation between certain network measures such as density, centrality and betweenness and coordination performance measures of defect management systems such as quality and timeliness.     

我国区域税收转移的成因与影响

目前中国存在税收与税源背离现象,税收转移大致呈现出由经济欠发达地区向发达地区转移的特征。其原因是：企业汇总纳税、总部经济、省际贸易、资源性产品价格扭曲、税制设计不尽合理、区域间税收竞争、税收政策区域差异、集团公司转让定价、隐形的税收转移、内外资企业迁移。税收与税源的背离,会减少地方财力,加剧地区差距,降低经济效率,不利于保护资源和改善投资环境,影响政府形象与科学决策。对此,要树立科学税收观,建立与完善税收分配体制,促进经济可持续发展。
