A Constraint-based Approach for Annotating Music Scores with Gestural Information

The physical gestures that operate music instruments are responsible for the qualities of the sound being produced in a performance. Gestural information is thereby crucial for a model of music performance, paired with a model of sound synthesis where this information is applied. The highly constrained nature of performers gestures makes this task suitable to be modeled via a constraint-based approach, coupled with a strategy aimed at maximizing the gestural comfort of performers. We illustrate the problem representation, the search strategy and a validation of the model against human performance.

关于混凝土四面体截流材料的探讨

通过对比混凝土四面体与特大块石这两种截流材料的抗冲稳定性和施工的方便性,分析了混凝土四面体截流材料在工程应用中存在的问题。指出:①混凝土四面体密度、综合稳定系数、化引球形粒径都偏小,在龙口的抗冲稳定性不如特大块石;②混凝土四面体制作麻烦,成本高,占地面积大,装运困难,抛投强度低,施工不如特大块石方便;③在截流施工中宜优先使用特大块石,慎用混凝土四面体。     

Do High-Achieving Female Students Underperform in Private? The Implications of Threatening Environments on Intellectual Processing.

Stereotype threat research has demonstrated that stereotypes can harm student performance in the face of public evaluation by peers or an experimenter. The current study examined whether stereotypes can also threaten in private settings. Female students completed a math test in 3-person groups, which consisted of either 2 other women (same gender) or 2 men (minority). In addition, students either believed their performance would be broadcasted to their peers (public) or not (private). Results revealed that minority students performed worse than same-gender students in both public and private environments. This finding supports the concept of threatening intellectual environments and shows how far reaching the effects of stereotypes can be. The authors discuss these findings in relation to research on tokenism and to stereotype threat and its educational implications. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
