Do Professionals Choke Under Pressure?
Do Professionals Choke Under Pressure? High rewards or the threat of severe punishment do not only provide incentives to exert high levels of effort but also create pressure. Such pressure can cause paradoxical performance effects, namely performance decrements despite strong incentives and high motivation. By analyzing the performance of professional football players on a well-defined task, na...
متن کاملUnderstanding CHOKe
A recently proposed active queue management, CHOKe, is stateless, simple to implement, yet surprisingly effective in protecting TCP from UDP flows. As UDP rate increases, even though the number of UDP packets in the queue rises, its bandwidth share eventually drops to zero, in stark contrast to the behavior of a regular FIFO buffer. We derive a detailed model of CHOKe that accurately predicts t...
متن کاملP-CHOKe: A Piggybacking-CHOKe AQM Congestion Control Method
Abstract— The Active Queue Management (AQM) is a technique that consists of ECN (Explicit Congestion notifications) in internet routers. Congestion is an important issue which researcher focuses on in the TCP network environment. AQM is a router – based mechanism for early detection of congestion inside the network. This paper provides an analysis of congestion metric with flow information in q...
متن کاملGeneralizing the CHOKe flow protection
This paper proposes a simple and stateless active queue management (AQM) scheme, called geometric CHOKe (gCHOKe), to protect responsive flows from unresponsive ones. gCHOKe has its root on and is a generalization of the original CHOKe. It provides an additional power of protection, achieved by introducing an extra flow matching trial following each successful flow comparison of packets. The max...
متن کاملHow do usability professionals construe usability?
Usability professionals have attained a specialist role in systems-development projects. This study analyzes usability professionals’ operational understanding of usability by eliciting the constructs they employ in their thinking about system use. We approach usability broadly and without a priori distinguishing it from user experience. On the basis of repertory-grid interviews with 24 Chinese...
