Initiating private-collective innovation: The fragility of knowledge sharing

Incentives to innovate are a central element of innovation theory. In the private-investment model, innovators privately fund innovation and then use intellectual property protection mechanisms to appropriate returns from these investments. In the collective-action model, public subsidy funds public goods innovations, characterized by non-rivalry and non-exclusivity in using these innovations. Recently, these models have been compounded in the private-collective innovation model where innovators privately fund public goods innovations. Private-collective innovation is illustrated in the case of open source software development. This paper contributes to the work on this model by investigating incentives that motivate innovators to share their knowledge in an initial situation, before there is a community to support the innovation process. We use game theory to predict knowledge sharing behavior in private-collective innovation, and test these predictions in a laboratory setting. The results show that knowledge sharing is a coordination game with multiple equilibria, reflecting the fragility of knowledge sharing between innovators with conflicting interests. The experimental results demonstrate important asymmetries in the fragility of knowledge sharing and, in some situations, more knowledge sharing than theoretically predicted. A behavioral analysis suggests that knowledge sharing in private-collective innovation is not only affected by material incentives, but also by social preferences such as fairness. The results offer general insights into the relationship between incentives and knowledge sharing and contribute to a better understanding of the initiation of private-collective innovation.

太阳能-地源热泵系统的交替运行特性

为了探讨太阳能-地源热泵系统的交替运行特性,提出并定义了各交替运行模式,建立了交替运行时考虑冻融相变的U形埋管周围土壤传热模型.基于对该模型的数值求解,探讨了各交替运行模式下地下埋管周围土壤温度的变化趋势.结果表明：各交替运行模式均可有效改善埋管周围土壤温度的恢复效果,对于无太阳能补热的昼夜交替与短时间间隔交替运行模式,在以24h为交替运行周期时,其太阳能热源承担的时间比例可控制在50%～58%;同时,利用日间太阳能补热来强制土壤温度的恢复,可有效克服土壤温度的自然恢复缺陷,与其他交替模式综合使用可达最佳运行效果.此外,利用钻孔壁实测数据对所建模型的预测精度进行了验证.研究结论可为太阳能-地源热泵系统的优化运行提供参考.

Factorial and convergent validity of the Exercise Identity Scale in a German adult sample

The purpose of the present study was to examine the factorial and convergent validity of the German translation of the Exercise Identity Scale (EIS; Anderson & Cychosz, 1994). We introduce a bifactor model as a possible alternative to the previously discussed one- and two-factor models. Using an online study with 530 participants, our results suggest that the EIS should be considered a unidimensional measure. For this one-factor model, temporal invariance (time interval: 2 weeks) and invariance between men and women could be established. Relations to similar constructs were in the expected directions. We provide a psychometrically sound German version of the EIS, which demonstrated factorial and convergent validity in this study. The use of the scale in German samples is likely to advance research on exercise adoption and maintenance by integrating the exercise identity construct.
