In cities, positive self-organization, reflecting the preferred pattern formation resulting from dissipative decision making of activities, is a key promoter of urban dynamics. The urban planning system is limited in recognizing it, but planners adapt to these autonomous processes by deviating from the plan. The result is a dual system of rules and systematic exceptions, which lacks the ability to steer and evaluate the overall direction of urban progress. Similar yet explicit dual problem-solving procedures of statutory rule frameworks and adaptations applying previous cases are common in many fields. Applying this multi-disciplinary knowledge, I propose a dual, computation-supported planning procedure combining rule-based and case-based reasoning. Such planning could respond to urban self-organization, while guiding urban dynamics in a consistent manner. The operation of this coupled system is illustrated using the empirical example of Lielahti, a mixed-use working place district in the Finnish city of Tampere in an exploratory manner.

22 pags., 8 figs., 4 tabs., 1 app. ; A dedicated spectroscopic study of the β decay of Cd127 was conducted at the IGISOL facility at the University of Jyväskylä. Following high-resolution mass separation in a Penning trap, β-γ-γ coincidences were used to considerably extend the decay scheme of In127. The β-decaying 3/2+ and 11/2- states in Cd127 have been identified with the Cd127 ground state and the 283-keV isomer. Their respective half-lives have been measured to 0.45(812)s and 0.36(4) s. The experimentally observed β feeding to excited states of In127 and the decay scheme of In127 are discussed in conjunction with large-scale shell-model calculations. ; The authors thank the accelerator staff at the University of Jyväskylä.
