To be considered a genius, that composer has to make work that is considered original and innovative, and that demonstrates a profound variation of ideas and associations between concepts that are often unexpected.
We sampled for maximum variation of ideas and perceptions (i.e. heterogeneity sampling, a subcategory of purposive sampling), with the aim of recruiting sufficient numbers to allow thematic saturation to be reached (Silverman 2001, pp. 250 254).
However, our intention in this first step of the development process was to collect a wide variation of ideas representing both those who were and were not comfortable internet users.
Phenomenography is a tool particularly suited to answering educational research questions about thinking and learning (Marton, 1986) and also allowed us to describe the variation of ideas, both correct and incorrect, held by students in our test population.
Endless variations of tiny ideas are debated heatedly, as if they could alter the objective conditions of the Cuban regime, and the illusion of progress is maintained.
The first few homotopy groups of spheres can be computed using ad hoc variations of the ideas above; beyond this point, most methods for computing homotopy groups of spheres are based on spectral sequences.
We sampled purposively for maximum variation 45 of ideas, deliberately inviting participants with strongly divergent opinions (table 1).
Some scientists are already experimenting with variations of this idea within the stately world of peer review.
