Participants were asked to try their best to match a word to every presentation of the letter.
I left an empty chair at every conference, every award ceremony, every presentation of my books.
Before every trial, i.e., before every presentation of an image, drift was measured by letting the participant focus on a cross displayed in the center of the screen, and the estimation corrected if necessary.
As this was the first time that the assays were applied clinically, they were very carefully validated with respect to specificity, precision and applicability by all available methods including reverse isotope dilution (Gallagher et al., 1958), a point that was extensively debated at every presentation of new findings (discussion in Brown and Matthew, 1962).
Not every presentations is of particular aesthetic value, though; in order to be so, it has to become the object of an emotion in which one correctly takes a positive stance towards it.
Also, at the beginning of every North Korean presentation, the scientist would start by paying a tribute to the great leader, saying that this research was being done because he had identified the importance of environmental health.
They may not be able to choreograph the give and take of an actual bout, but they insist on control of every aspect of its presentation: each graphic, each dart of light, each selection of psych-up music, each word and image in the promos of the fighters, each barely clad "octagon girl" who circles the cage holding a number ostensibly meant to remind the forgetful of the round.
The other notable aspect of almost every vendor presentation at Enterprise 2.0 was the presence of a prominently featured Salesforce.com integration.
