The sorting techniques: a tutorial paper on card sorts, picture sorts and item sorts
Although sorting techniques (e.g. card sorts) are widely used in knowledge acquisition and requirements acquisition, they have received little formal attention compared to related techniques such as repertory grids and laddering. This paper briefly describes the main sorting techniques, and then provides a detailed tutorial on one variety (repeated single-criterion sorts), using a worked exampl...
متن کاملA Duality of Sorts
Sorting algorithms are one of the key pedagogical foundations of computer science, and their properties have been studied heavily. Perhaps less well known, however, is the fact that many of the basic sorting algorithms exist as a pair, and that these pairs arise naturally out of the duality between folds and unfolds. In this paper, we make this duality explicit, by showing how to define common ...

The essential instrument settings are shown in Table 1. ‘Enzyme reagent was loaded as “2nd reagent,” and the modified color reagents A and B were “4th reagent” and “3rd reagent,” respectively. The instrument incubated sample and enzyme reagent for 4 mm in the inner chamber of the rotor. It then added 4-aminophenol to the inner chamber and sodium hydroxide to the outer chamber, mixed the content...
متن کاملFast Exchange Sorts 1
We present three variations of the following new sorting theme: Throughout the sort, the array is maintained in piles of sorted elements. At each step, the piles are split into two parts, so that the elements of the left piles are smaller than (or equal to) the elements of the right piles. Then, the two parts are each sorted, recursively. The theme, then, is a combination of Hoare's Quicksort i...
متن کاملGenitive Modifiers, Sorts, and Metonymy
Our long-term goal is to contribute to the integration of formal and lexical semantics. Our more immediate theoretical starting point is the idea of “text as theory”, within a model-theoretic semantic framework. We describe a set of empirical problems in the domain of genitive modifiers which offer a challenge to theories of the integration of lexical, compositional, and contextual information....
