Spatial Asymmetries in the Fl Anker-congruency Effect: Attentional Scanning Is Biased by Fl Anker Orientation

If targets are fl anked by congruent or incongruent distractors, performance is facilitated or impaired, respectively. Prior studies revealed that, with normal letters, this fl anker effect is more pronounced with leftthan with right-side fl ankers. The present study shows that the left-side bias is eliminated if the fl ankers (but not the target) are mirrored (Experiment 1). If the orientation...

Interview with Gitte Lindgaard on visual appeal and aesthetics in human-technology interaction

Dr. Gitte Lindgaard is Director of the Human Oriented Technology Lab (HOT Lab) at Carleton University, Ottawa, Canada and Professor holding a NSERC/Cognos Chair in User-Centered Product Design. She published various articles on visual appeal and aesthetics in human-technology interaction. In this interview she summarizes the main outcomes of her research and discusses aspects for further resear...

A new species of the alpheid shrimp genus Triacanthoneus Anker, 2010 (Crustacea: Alpheidae) from Belize.

A new species of the alpheid shrimp genus Triacanthoneus Anker, 2010, is described based on material collected in a marine cave off Caye Chapel, Belize. Triacanthoneus chapelianus sp. nov. is the fifth species in the genus and can be distinguished from the other four species by the position of the dorsolateral teeth on the carapace, which in the new species have an anterior (= submarginal) posi...

Achieving per-flow Queueing Performance without a per-flow Queue

Recent studies have shown that suitably-designed packet discard policies can dramatically improve the performance of fair queueing mechanisms in internet routers. The Queue State Deficit Round Robin algorithm (QSDRR) preferentially discards from long queues, but introduces hysteresis into the discard policy to minimize synchronization among TCP flows. QSDRR provides higher throughput and much b...
