Some Extensions of Mills's Method for Urban Population Density Gradient Estimation

This paper extends Milk's method for estimating urban population density gradients to general noncircular and asymmetrical urban forms, using Gauss-Legendre quadrature embedded in a Newton-Raphson root finding algorithm. We also examine the sensitivity of the Mills method to measurement errors in the assumptions. Several issues arising from the comparison of analytical, Mills type estimation procedures with statistical procedures are explored, particularly in light of recent work that questions the negative exponential formulation of urban density gradients. We note in particular the influence of secondary population centers as a source of estimation bias.     

Performing space across time: a 520-year anniversary in a western Ukrainian village

Abstract

Festivals and celebrations have special significance for the foundation of community and collective memory. They are part of social practice and, at the same, also reveal much about current and historical social structures, traditions and rituals. Festivals contrast with everyday life, taking participants away from it; celebrations, conversely, celebrate and reinforce social hierarchies, the role of individuals in the community and the characteristics of the community. This is clearly demonstrated in this contribution on the example of the festivities of two western Ukrainian village communities celebrating 520 years of existence. The communities’ notable peculiarity lies in the fact that they were founded as a single village. Due the partitioning of Poland along the Zbru? River, however, the two sides were situated in Austria-Hungary and Russia, respectively. In the interwar period, they were located in Poland and the Soviet Union. Since the end of the Second World War, they were part of the Ukrainian Soviet Socialist Republic. Although they did not have borders for the first time in 150 years, they nevertheless continued to exist as independent villages. Given this starting point, a celebration of the 520th anniversary of the founding of these communities obviously has very complex historical contexts within different past state regimes. The following analysis of the village festival will first demonstrate how such a celebration was achieved. Further, it will examine the extent to which a socio-spatial demarcation was reproduced just as efforts were simultaneously made to eliminate it. The village is a striking example of the manifestation of the experience and perception, design and imagination of present and past spaces.     

‘Together apart’ or ‘apart together’? – middle-class parents’ choice of playgrounds and playground interactions in socially diverse neighbourhoods

Taking an everyday life setting, namely playgrounds, as a starting point, the paper foregrounds a nuanced analysis of the internal differentiations of the middle class’s positioning in regard to social diversity. In so doing, the paper contributes to debates on contemporary segregation research, (dis-)affiliation of the middle classes in inner-city diverse neighbourhoods and geographies of encounter. Empirical findings are based on an analysis of the narratives and daily spatial routines of middle-class parents in three inner-city neighbourhoods in a major German town. The findings contradict the conventional wisdom that middle-class parents would always seek a socially homogeneous environment in which to raise their children and show the presence of a middle-class fraction with a collective orientation. The analysis highlights the need for a closer look at playgrounds as a setting for cross-social interaction and, in terms of micro-level politics, a setting to promote diverse and inclusive neighbourhoods.     

Der Weg zum Flussgebietsmanagement

Zusammenfassung Der Flussgebietsansatz ist ein zentrales Element der Wasserrahmenrichtlinie (WRRL) und wurde in Deutschland im Zuge der organisatorischen Umsetzung der Richtlinie strukturell implementiert. Die Kooperationsstrukturen auf Flussgebietsebene sollen dabei einen funktionierenden Rahmen auch für die fachliche Umsetzung der Richtlinie bilden. Beim dazu erforderlichen strukturellen Wandel waren insbesondere die in den Flussgebieten bereits vorhandenen Kooperationsstrukturen von Bedeutung. Diese wurden entweder ausgebaut, umstrukturiert oder von neuen Strukturen zur Umsetzung der WRRL überlagert. Die dabei zum Teil entstandenen Doppelstrukturen erh?hen jedoch den Koordinierungsaufwand der Akteure stark, so dass es aktuell zu einer Zusammenführung und Konsolidierungsbewegung kommt. Allerdings wird auch nach der Konsolidierung eine gro?e strukturelle Vielfalt in den Flussgebieten verbleiben, die durch eine enge Zusammenarbeit der Akteure zu bew?ltigen ist. Es bleibt abzuwarten, inwiefern diese Strukturen sich auch eignen, um neuen Herausforderungen, wie beispielsweise den Folgen des Klimawandels, zu begegnen.     

Drugs, Sex, Rock, and Roll: A Theory of Morality Politics

I assume that (a) the demand for sin is characterized by heterogeneous preferences and (b) private behavior diverges from public statements. From these assumptions, in the first section of this article I derive a series of propositions about morality policy. Rational politicians will perceive that demand for restrictive policies will be greater than it actually is and thus compete to produce more extreme policies. Bureaucracies will lack expertise and thus will not provide a check on political excesses. This "politics of sin" can be translated into a contemporary form of redistributive morality policy politics if the issue can be refrained by political actors to legitimate an opposition position. In the second portion of the article, I argue formally that sin policies in general will fail because they operate on subsets of the population that are more and more resistant to the policy instruments available to government. I conclude with potential expansions of this theory, including how it might be generalized to other types of public policy.
