BGP路由摆动抑制机制与路径探索

路由摆动抑制是普遍用于网络路由协议的一种机制。其目的在于通过暂时抑制那些短期内发生快速变化的路由,而限制不稳定路由的全局影响。普遍认为这一抑制机制有助于Internet全局路由的稳定性,但研究表明BGP的路径探索可能错误地引发抑制,甚至仅仅一次路由摆动都可能导致路由收敛时间的大大增加。

Feedback complexity and corrective efficiency

College undergraduates read a 2400-word passage, responded to 16 multiple-choice questions, and received one of four types of feedback following their responses. Complexity of feedback was inversely related to both error correctability and criterion efficiency taken as a ratio of feedback study time to post-test corrects. The results were discussed in terms of depth of processing and instructional comprehension.

Getting children to do more academic work: Foot-in-the-Door versus Door-in-the-Face

In this study we explored whether compliance-without-pressure techniques, known to encourage adults to behave more altruistically, can be used to encourage children to do more academic work. Using three different approaches - Foot-in-the-Door, Door-in-the-Face, and Single-Request - we asked 60 6- to 8-year-old Hong Kong Chinese children to complete a 20-item arithmetic worksheet. The Door-in-the-Face technique was the most effective, eliciting the highest percentage of children who agreed to do the target task, requiring the least adult input to sustain engagement in the task, and producing the greatest amount of accurate work.
