An outcome of the new approach is a reduction of equations of a dynamic system of any complexity to a set of the matrix final equations, linear and bilinear equations, for which the solution's difficulties are fundamentally less than the solution's difficulties of the same problems in conventional representations.
It is, of course, a sympathetic voice, especially when joshing the passive aggression of wig-wearers ("you lot are going to have to collude in the illusion that I've still got a barnet") or, in a lovely closing routine, negotiating the social difficulty of encountering the same vague acquaintance three times on one shopping trip.
But the district attorney's willingness to compromise on a life-without-parole sentence seemed a calculation about the difficulty of persuading the same 12 jurors to agree on capital punishment after they spent 10 days sifting evidence and acquitted Dr. Gosnell on one first-degree murder charge.
The physician my wife consulted said that the only drawback to the Australian system, in her opinion, was the difficulty of keeping the same general practitioner, as there were some 44,000 GPs in Australia, and a patient had to see whoever was available at the time needed.
Backpacks were not removed due to the difficulty of recapturing the same individual (Penteriani & Delgado unpublished data).
The use of multiple levels of difficulty within the same basic task paradigm also allows us to probe how localization and lateralization of function might change with task demands.
In the case of the puzzle difficulties, there is a large difference between the "medium" difficulty level and the "hard" difficulty level; one of the puzzles on the "medium" level requires only simple pattern recognition, while the "hard" difficulty level version of the same puzzle requires knowledge of Shakespeare plays to complete.
As participants were not asked to re-estimate the level of difficulty with the same activity at post mSTEPS, and thus a change in activity-specific disability could not be calculated, we chose to tabulate the frequencies of reported difficulties with commonly listed activities, and to use the data for a baseline sample description only.
Thirty-one questions assessing the level of difficulty in most of the same activities but taking into account any kind of technical aid or personal assistance were also asked.
