GIS-gestützte kleinr?umige Analyse von amtlichen Schuldaten Ein Ansatz für ein fl?chendeckendes Bildungsmonitoring am Beispiel des Ruhrgebiets

In unserer Gesellschaft sind Bildungserfolg und weitergehende Ausbildung in hohem Ma?e von der sozialen Herkunft abh?ngig. Im Rahmen eines Bildungsmonitorings werden kleinr?umige Daten zur Sozialstruktur der Stadtgebiete mit Schuldaten in Verbindung gebracht und mit Hilfe eines Geographischen Informationssystems (GIS) r?umlich ausgewertet. Es zeigt sich, da? sich Bildungschancen systematisch entlang von Grenzen sozialer und sozialr?umlicher Ungleichheit verteilen. In den St?dten spiegelt sich die Segregation der Bev?lkerung in einer r?umlichen Bildungsdisparit?t wider. In eher „bürgerlichen“ Stadtgebieten besuchen die meisten Kinder ein Gymnasium—in den ?rmeren Gebieten sind Hauptschule und Gesamtschule die h?ufigsten Schulformen. Der Bildungsmonitor erm?glicht eine recht pr?zise Beschreibung des unterschiedlich schwierigen „Gel?ndes“, in dem Bildungseinrichtungen operieren, und erlaubt eine Sch?rfung und Evaluierung der Schulprofile bezogen auf die Eigenheiten der unterschiedlichen Sozialr?ume.     

THE TIME OF POLITICS,THE POLITICS OF TIME,AND POLITICIZED TIME: AN INTRODUCTION TO CHRONOPOLITICS

Time is so deeply interwoven with all aspects of politics that its centrality to the political is frequently overlooked. For one, politics has its own times and rhythms. Secondly, time can be an object and an instrument of politics. Thirdly, temporal attributes are used not only to differentiate basic political principles but also to legitimize or delegitimize politics. Finally, politics aims at realizing futures in the present or preventing them from materializing. Consequently, the relationship between politics and time encompasses a broad spectrum of phenomena and processes that cry out for historicization. In our introduction to this History and Theory theme issue on chronopolitics, we argue that the concept of chronopolitics makes it possible to do this and, in the process, to move the operation of rethinking historical temporalities from the periphery toward the center of historiographical attention as well as to engage in a dialogue with scholars from a wide range of disciplines. To this end, we propose a broad concept of chronopolitics by discussing existing definitions, by distinguishing between three central dimensions of chronopolitics (the time of politics, the politics of time, and politicized time), and by systematizing possible approaches to studying chronopolitics.     

Rural regeneration strategies for declining regions: trade-off between novelty and practicability

ABSTRACT

Innovation comprises both novelty and practicability. These two dimensions of innovation correlate partly negatively in our analysis of survey data about planning processes in declining rural districts. As argued in the literature, declining regions need innovative concepts beyond traditional counteracting strategies to ‘shrink smart’. Competitions are suggested as feasible-to-initiate innovative local concepts by the state. The German Federal Ministry of Food and Agriculture invited 39 particularly affected rural districts to participate in such a competition among the best concepts. We address the questions of how the districts dealt with the requirements for novelty and practicability in their concepts and how the rules of competitive bidding procedures influence those concepts. Answering these questions, we conducted a survey and statistically tested hypotheses deduced from governance and innovation theory. Moreover, we analysed the bidding documents. The results show that most districts came up with hardly novel and only partly practicable concepts because the organization of the competition, and local bargaining processes impede innovation. Furthermore, the ministry’s requirements for the competition overburdened local actors with a lack of resources in declining regions. As a policy implication, we propose to integrate external experts in local networks and to accompany declining regions over a longer time instead of short-term competitions and projects.     

DEMOGRAPHIC PROXIES FOR THE NEOLITHIC: WITH EMPHASIS ON THE LANGELAND REGION,DENMARK

The article discusses the use of summed probability distribution as a demographic proxy, and highlights several issues with this method, especially during periods of change in the exploitation of the landscape or during social transformation. With a case study from the Langeland region in Denmark an alternative and corrective approach is applied, were number of settlements and size of settlement is included. With this approach a very different development can be described.     

Explaining Advocacy Coalition Change with Policy Feedback

Despite the prominence of exogenous factors in theories of policy change, the precise mechanisms that link such factors to policy change remain elusive: The effects of exogenous factors on the politics underlying policy change are not sufficiently conceptualized and empirically analyzed. To address this gap, we propose to distinguish between truly exogenous factors and policy outcomes to better understand policy change. Specifically, we combine the Advocacy Coalition Framework with policy feedback theory to conceptualize a complete feedback loop among policy, policy outcomes, and subsequent politics. Aiming at theory-building, we use policy feedback mechanisms to explain why advocacy coalitions change over time. Empirically, we conduct a longitudinal single case study on policy-induced technological change in the German energy subsystem, an extreme case of policy outcomes, from 1983 to 2013. First, using discourse network analysis, we identify four patterns of actor movements, explaining coalition decline and growth. Second, using process tracing, we detect four policy feedback mechanisms explaining these four actor movements. With this inductive mixed-methods approach, we build a conceptual framework in which policy outcomes affect subsequent politics through feedback mechanisms. We develop propositions on how coalition change and feedback mechanisms explain four ideal-typical trajectories of policy change.     

THE FORMATION OF EARLY NEOLITHIC COMMUNITIES IN THE CENTRAL ZAGROS: AN 11,500 YEAR‐OLD COMMUNAL STRUCTURE AT ASIAB

Communal buildings have been reported from a number of early Neolithic sites from the Levant and Anatolia, but none were known from the central Zagros. Here we report on the recent excavations at Asiab, Kermanshah province, Iran, and argue that the principal feature found during Robert Braidwood’s excavation at the site in 1960 should be interpreted as an example of a communal building. We discuss the results of the previous and recent excavations, highlight the key features of this building, and the implications for our understanding of the early Neolithic in the ‘eastern wing’ of the Fertile Crescent.     

Infrared radiofluorescence (IR-RF) dating of middle pleistocene fluvial archives of the Heidelberg Basin (Southwest Germany)

The infrared radiofluorescence (IR-RF) dating technique was applied to eight fluvial samples that were collected from two sediment cores at the Heidelberg Basin located near Viernheim and Ludwigshafen in southwest Germany. Based on the IR-RF derived ages of the samples it was possible to establish a chronological framework for the Mid-Pleistocene fluvial deposits of the Heidelberg Basin. The results allow us to distinguish between four main periods of aggradation. The lowermost sample taken from 100 m core depth lead to an IR-RF age of 643 ± 28 ka pointing to a Cromerian period of aggradation (OIS 17–16). For the Elsterian it is now possible to distinguish between two aggradation periods, one occurring during the Lower Elsterian period (OIS 15) and a second during the Upper Elsterian period (OIS 12–11). For the so called Upper interlayer (or “Oberer Zwischenhorizont” — a layer of organic-rich and finer-grained deposits), the IR-RF results point to a deposition age of around 300 ka, with samples taken directly on top and out of this layer yielding IR-RF ages of 288 ± 19 ka and 302 ± 19 ka, respectively. Hence, the measured IR-RF ages clearly point to a deposition during the Lower Saalian period (OIS 9–8) whereas earlier studies assumed a Cromerian age for the sediments of the Upper Interlayer based on pollen records and also mollusc fauna. The new IR-RF dataset indicates that significant hiatuses are present within the fluvial sediment successions. In particular the Eemian and Upper Saalian deposits are missing in this part of the northern Upper Rhine Graben, as the 300 ka deposits are directly overlain by Weichselian fluvial sediments. It is obvious that time periods of increased fluvial aggradation were interrupted by time periods of almost no aggradation or erosion which should have been mainly triggered by phases of increased and decreased subsidence of the Heidelberg Basin.
