Designing interviews to generate rich data for information systems research
Article history: Received 8 November 2010 Received in revised form 21 November 2010 Accepted 21 November 2010 Available online 17 December 2010 Information Systems (IS) publications that use interviews for data generation tend to provide very little insight into the research process andvery few rely on a carefully chosenandwell-articulated interviewing method. Given the wide variety of intervie...
متن کاملCharacterizing rosy theories
We examine several conditions, either the existence of a rank or a particular property of þ-forking that suggest the existence of a well-behaved independence relation, and determine the consequences of each of these conditions towards the rosiness of the theory. In particular we show that the existence of an ordinal valued equivalence relation rank is a (necessary and) sufficient condition for ...
متن کاملBiology of rosy apple
In surveys of apple-production areas east of the Cascade Mountains of Washington, broadleaf plantain, Plantago major Linnaeus (Plantaginaceae) was common throughout while narrowleaf plantain, P. lanceolata Linnaeus, was most common south of Orondo, Douglas County (47.7u latitude). Rosy apple aphid was the most common aphid on these two herbaceous plants; however, colonies were scarce, on only 1...
متن کاملProduct rosy labeling of graphs
In this paper we describe a natural extension of the well-known ρ-labeling of graphs (also known as rosy labeling). The labeling, called product rosy labeling, labels vertices with elements of products of additive groups. We illustrate the usefulness of this labeling by presenting a recursive construction of infinite families of trees decomposing complete graphs.
متن کاملMetric-Driven RoSy Fields Design
Designing rotational symmetries on surfaces is an important task for a wide range of graphics applications. This work introduces a rigorous and practical algorithm for automatic N-RoSy design on arbitrary surfaces with user defined field topologies. The user has full control of the number, positions and indices of the singularities, the turning numbers of the loops, and is able to edit the fiel...
