This paper describes the Facilitation Tool, a tool built to untangle two problems that we find in current Group Decision Support Systems. If we want to allow facilitators manage such systems with success, then a planning functionality more detailed than the currently available is necessary. We also found very limited support to remote facilitation. Several notions concerning decision-making and...

The lateral entorhinal cortex receives strong inputs from midbrain dopamine neurons that can modulate its sensory and mnemonic function. We have previously demonstrated that 1 µM dopamine facilitates synaptic transmission in layer II entorhinal cortex cells via activation of D1-like receptors, increased cAMP-PKA activity, and a resulting enhancement of AMPA-receptor mediated currents. The prese...

The thresholds of human observers detecting line targets improve significantly when the targets are presented in a spatial context of collinear inducing stimuli. This phenomenon is referred to as spatial facilitation, and may reflect the output of long-range interactions between cortical feature detectors. Spatial facilitation has thus far been observed with luminance-defined, achromatic stimul...

Background Facilitation of local women’s groups may reportedly reduce neonatal mortality. It is not known whether facilitation of groups composed by local healthcare staff and politicians can improve perinatal outcomes. We hypothesized that facilitation of local stakeholder groups would reduce neonatal mortality (primary outcome) and improve maternal, delivery and newborn care indicators (secon...

Dear Sir, A paradoxical effect of light has been observed in some invertebrate photoreceptors: an increased amplitude of electrophysiological responses to test flashes following illumination by a step or flash of light. This apparent increase in photoreceptor sensitivity is known as facilitation, and is in contrast to the better known case of reduced sensitivity following illumination (light ad...

Repetitive stimulation often results in habituation of the elicited response. However, if the stimulus is sufficiently strong, habituation may be preceded by transient sensitization or even replaced by enduring sensitization. In 1970, Groves and Thompson formulated the dual-process theory of plasticity to explain these characteristic behavioral changes on the basis of competition between decrem...

One of the greatest challenges in contemporary condensed matter physics is to ascertain whether the formation of glasses from liquids is fundamentally thermodynamic or dynamic in origin. Although the thermodynamic paradigm has dominated theoretical research for decades, the purely kinetic perspective of the dynamical facilitation (DF) theory has attained prominence in recent times. In particula...

Short-term facilitation and depression coexist at many CNS synapses. Facilitation, however, has not been fully characterized at hair cell synapses. Using paired recordings and membrane capacitance measurements we find that paired-pulse plasticity at an adult frog auditory hair cell synapse depends on pulse duration and interpulse intervals. For short 20 ms depolarizing pulses, and interpulse in...

Investment facilitation, which tackles ground-level obstacles to FDI and has no substantial challenges regulatory space, is emerging as a new trend of global governance. Meanwhile, the content method implement investment facilitation are still evolving. Both top destinations largest countries in South America Asia respectively, Brazil China have adopted somewhat different approaches towards fac...

At Aplysia sensory-to-motor neuron synapses, the inhibitory neuropeptide Phe-Met-Arg-Phe-NH2 (FMRFa) produces depression, and serotonin (5-HT) produces facilitation. Short-term depression has been found to result from the activation of a phospholipase A2. The released arachidonate is metabolized by 12-lipoxygenase to active second messengers. We find that FMRFa leads to the phosphorylation and ...
