Tight and Loose Semantics for Transformation Systems
When defining the requirements of a system, specification units typically are partial or incomplete descriptions of a system component. In this context, providing a complete description of a component means integrating all the existing partial views for that component. However, in many cases defining the semantics of this integration operation is not an easy task. In particular, this is the cas...
متن کاملDifferences between tight and loose cultures: a 33-nation study.
With data from 33 nations, we illustrate the differences between cultures that are tight (have many strong norms and a low tolerance of deviant behavior) versus loose (have weak social norms and a high tolerance of deviant behavior). Tightness-looseness is part of a complex, loosely integrated multilevel system that comprises distal ecological and historical threats (e.g., high population densi...

متن کاملWaste Makes Haste: Tight Bounds for Loose Parallel Sorting
Conventional parallel sorting requires the n input keys to be output in an array of size n, and is known to take fl(log n/log log n) time using any polynomial number of processors. The lower bound does not apply to the more "wasteful" convention of padded sorting, which requires the keys to be output in sorted order in an array of size (1 + o(1))n. We give very fast randomized CRCW PRAM algorit...
متن کاملThe media of sociology: tight or loose translations?
Sociologists have increasingly come to recognize that the discipline has unduly privileged textual representations, but efforts to incorporate visual and other media are still only in their beginning. This paper develops an analysis of the ways objects of knowledge are translated into other media, in order to understand the visual practices of sociology and to point out unused possibilities. I ...
