Children's Conceptions of Ownership for Self and Other: Categorical Ownership Versus Strength of Claim

Children are capable of viewing object ownership as categorical and exclusive, but ownership claims can also vary by degree. This study investigated how children use these different conceptions of ownership in a giving and a taking task. In two studies, 4- to 7-year olds (N = 105) could give and take craft objects that they or another child had found (weaker claim) and made (stronger claim). In Study 1, no additional ownership information was given, and in Study 2 categorical ownership was stated (“these belong to you”). The results showed that children used categorical ownership for their own objects but used ownership strength for the other child's objects, taking more of the found items.

从重数量到重质量：高校博士生奖学金评定的科研成果评价转向

科研成果是评定博士生奖学金的核心要素,对科研成果如何评价会影响奖学金制度对博士生的激励和引导作用。目前,高校博士生奖学金评定的科研成果评价存在重数量的现象。随着新时代我国研究生教育迎来高质量发展的新主题,这一评价应从重数量转向重质量,并在实践进路上,树立科研成果评价的质量观念,实行代表性科研成果评价制,构建“五维”科研成果评价标准,建构基于同行专家评价的科研成果评价机制,优化科研成果评价反馈信息的运用机制,构建以科研成果为核心的保障性评价指标。

成本信息不完全共享下同质技术创新扩散研究

为探讨成本信息不完全共享下同质技术创新扩散的均衡问题,以2家同质技术创新扩散企业为研究对象,利用修改后的Lotka-Volterra模型建立了扩散模型和利润模型,计算出技术扩散的稳定态.通过分析纳什均衡与贝叶斯均衡,计算了成本信息不完全共享下的产量,并结合示例进行了验证.结果表明:无论成本信息是否共享,技术扩散影响系数大的企业将形成市场占有优势;当双方的扩散影响系数较小且相当时,将形成技术扩散共存状态,此时,成本信息劣势方的产量将位于该方依据观测到的对手低成本和高成本而预计的最优产量之间,无法达到最优竞争均衡.
