Many computational tools for the simulation and design of emergency evacuation and egress are now available. However, due to the scarcity of human and social behavioral data, these computational tools rely on assumptions that have been found inconsistent or unrealistic. This paper presents a multi-agent based framework for simulating human and social behavior during emergency evacuation. A prototype system has been developed, which is able to demonstrate some emergent behaviors, such as competitive, queuing, and herding behaviors. For illustration, an example (...) application of the system for safe egress design is provided. (shrink)

For sociologists, interpretations of cultural objects, whether grouped into genres or taken individually, are intermediate steps toward understanding more fully the contexts in which they are produced. This does not deny the satisfaction implicit in grasping the significance of aspects of objects themselves; I hope that the analysis I have presented lends viewing the Sangatsu-dō sculptures a degree of comprehension, and pleasure, not present before. The ultimate test, however, and the justification for undertaking any sociological examination of cultural objects, is (...) the usefulness of the resulting account in confirming or rejecting ideas about the social conditions surrounding their production. The important question in judging the appropriateness of examining individual objects is therefore not whether sociologists (as opposed, for example, to art historians) ought to concern themselves with such analysis; it is whether such analyses increase the ability of objects to serve as evidence in investigations of interesting social phenomena. My goal is not therefore to supplant generic analysis with a focus on individual objects: it is as possible to fetishize the study of the object as it is to ignore its potential. In fact, it is most useful to see the two approaches as complementary, making possible fuller analyses than each can enable separately. We would do well to take more seriously the benefits of locating objects in the contexts in which people deal with them most commonly: as distinct elements in more inclusive fields, in which meaning and appeal are closely tied to difference.
