Sommario/riassunto

Spatial database management has become an important subarea of current database research. Research in this area is often characterized by interdisciplinary cooperation: computer scientists work with geographers andenvironmental scientists to provide better access to spatial databases of steadily increasing size. After the First Symposium on Large Spatial Databases (SSD '89) was held in Santa Barbara, California, in 1989 (and its proceedings published as Volume 409 of this series), a second symposium (SSD'91) was held in Zurich, Switzerland. This proceedings volume contains the papers presented at SSD '91. Topics include spatial data models and access methods, performance studies, geometric algorithms, spatial query languages and user interfaces, geographic information systems, and object-oriented techniques.

Sommario/riassunto

How are activation programs for the young unemployed implemented? How do street-level bureaucrats deal with competing rationalities and demands for action? Transition policies increasingly aim at promoting self-regulation and constructing employable subjects. Stephan Dahmen explores the practical regulation of biographical transitions in activation programs for the young unemployed by focusing on the interactive accomplishment of activation work. The study reveals how the critical tensions of activation policies are continually re-interpreted and adapted to local contingencies and describes the various organisational technologies used for creating employable subjects.
