Staying warm requires communication

Treating Raynaud phenomenon: Beyond staying warm.

Raynaud phenomenon is an overactive vascular response to cold and emotional stress that results in cutaneous color changes and sensory symptoms in the digits. It can be idiopathic (primary) or secondary to another condition; the latter can be more severe and more apt to lead to ischemic complications such as digital ulceration and even loss of digits. If nonpharmacologic interventions prove ina...

A Stable Marriage Requires Communication

The Gale-Shapely algorithm for the Stable Marriage Problem is known to take Θ(n2) steps to find a stable marriage in the worst case, but only Θ(n log n) steps in the average case (with n women and n men). In 1976, Knuth asked whether the worst-case running time can be improved in a model of computation that does not require sequential access to the whole input. A partial negative answer was giv...

Effective risk governance requires risk communication experts

Good decision making requires good communication.

The methods used for regulatory decisions must facilitate three kinds of communication: (i) with individual experts who must translate their knowledge into usable form; (ii) among the experts whose pooled knowledge informs those choices; and (iii) between regulators and those affected by their choices. Decision-making methods vary in their reliance on expert judgement and computational methods ...

Foveal Word Reading Requires Interhemispheric Communication

The left cerebral hemisphere is dominant for language processing in most individuals. It has been suggested that this asymmetric language representation can influence behavioral performance in foveal word-naming tasks. We carried out two experiments in which we obtained laterality indices by means of functional imaging during a mental word-generation task, using functional transcranial Doppler ...
