Migrations- und Integrationsforschung in der Praxis

Das aktuelle Interesse an Fragen der Migration und Integration von Ausl?ndern und eingebürgerten Deutschen hat zu einer gro?en Vielfalt an Forschungsans?tzen geführt. Die M?glichkeiten zur Analyse von Migrations- und Integrationsprozessen werden in einem hohen Ma?e durch die verfügbaren statistischen Daten und empirischen Umfrageergebnisse bestimmt, die spezifische Anforderungen erfüllen müssen. Der folgende Beitrag führt kurz in die besonderen Erfordernisse der Migrations- und Integrationsforschung ein und stellt eine Auswahl an Datenquellen vor. Im Mittelpunkt des Interesses steht der aktuelle Integrationssurvey des Bundesinstituts für Bev?lkerungsforschung, dessen Analysem?glichkeiten exemplarisch gezeigt werden.

Geographic concentrations in Turkey's manufacturing industry: identifying regional highpoint clusters1

The theory of economic development based on industry clusters emphasizes the importance of co-location of firms or industries with potential to share technical information and knowledge transfer. The paper identifies industry cluster templates in Turkey using the 1996 Turkish input/output table. Engineering and textile clusters are the largest ones with respect to the number of establishments and employment. Majority of manufacturing clusters are located in ?stanbul, ?zmir, Ankara/K?r?kkale and Çukurova districts. The study points out the importance of newly developing centres near the periphery of Ankara and several production centres in Anatolia.     

Post-Communist Corruption: In a League of its Own?

Conventional wisdom has it that the post-communist countries are in a league of their own with regard to corruption. At first sight, the levels of corruption are, indeed, particularly high in both presently communist and formerly communist countries. However, this generalization dissolves as a mirage when the proper control variables are included into the explanatory model. Countries with a communist past or a communist presence are as corrupt as one would expect based on other structural characteristics such as the level of economic development, a Protestant cultural tradition and the dependency on natural resources. Ceteris paribus, then, the communist legacy has no direct effect on contemporary levels of corruption. At most, it is possible to argue that it has an indirect effect working through the variable of economic development.     

Designs for Detecting Spatial Dependence

The aim of this article is to find optimal or nearly optimal designs for experiments to detect spatial dependence that might be in the data. The questions to be answered are: how to optimally select predictor values to detect the spatial structure (if it is existent) and how to avoid to spuriously detect spatial dependence if there is no such structure. The starting point of this analysis involves two different linear regression models: (1) an ordinary linear regression model with i.i.d. error terms—the nonspatial case and (2) a regression model with a spatially autocorrelated error term, a so-called simultaneous spatial autoregressive error model. The procedure can be divided into two main parts: The first is use of an exchange algorithm to find the optimal design for the respective data collection process; for its evaluation an artificial data set was generated and used. The second is estimation of the parameters of the regression model and calculation of Moran's I , which is used as an indicator for spatial dependence in the data set. The method is illustrated by applying it to a well-known case study in spatial analysis.

Relating the Ancient Ona Culture to the Wider Northern Horn: Discerning Patterns and Problems in the Archaeology of the First Millennium BC

Archaeological research carried out between 1998 and 2003 on the Asmara Plateau of Eritrea has provided new insights concerning the development of early-to-mid first millennium BC settled agropastoral communities in the northern Horn of Africa. The settlement, subsistence, and material culture of these communities in the greater Asmara area, referred to as the “Ancient Ona culture,” bear both unique qualities and striking similarities to coeval communities in Tigray, Ethiopia. This article provides an overview of regional settlement data and ceramic and lithic traditions from the greater Asmara area, drawing comparisons to other contexts of this period in the archaeology of the wider northern Horn. It is argued that we can see among the Ancient Ona sites distinct localized cultural expressions and development as well as strong links to a wider first millennium BC macro-cultural identity.     

The First Millennium <Emphasis Type="SmallCaps">bc</Emphasis> in the Highlands of Northern Ethiopia and South–Central Eritrea: A Reassessment of Cultural and Political Development

An overview is offered of the development of research—both archaeological and epigraphic—on the inhabitants of the northern Horn during the first millennium bc. Initially, reconstructions of this period placed considerable emphasis on links with southern Arabia and tended to group those into a single cultural category that was designated ‘Pre-Aksumite’. It is now argued that long-distance contacts were much less pervasive, being largely restricted to the élite, and that other aspects of life—including much material culture and subsistence economy—displayed strong local continuity from earlier times. Similarly, it is argued that interpretation of the epigraphic evidence as indicating a single ‘Pre-Aksumite’ state called D'MT is unjustified.
