DECOMPOSING REGIONAL EFFICIENCY*

ABSTRACT Applying an outlier robust extension of the data envelopment analysis (DEA) followed by a geoadditive regression analysis, this study identifies and decomposes the efficiency of 439 German regions in using infrastructure and human capital. The findings show that the regions’ efficiency is driven by a spatial and a nonspatial, arguably structural factor. As a consequence, concrete regional funding schemes, shaped by best practice results, might not be appropriate for all regions. Instead, a more differentiated funding scheme that accounts for both spatial and structural factors seems more promising.     

Contribution of Local Agenda 21 to Practical Implementation of Sustainable Development: The Case of the Czech Republic

Local Agenda 21 (LA21), a voluntary tool for implementing sustainable development (SD) in local level, is one way of implementing sustainability principles in practice. Twenty years after the United Nations Conference on Environment and Development Conference in Rio de Janeiro, which made the first reference of LA21 (intended as a framework for the twenty-first century respecting SD principles), this article deals with evaluating the real contribution of this initiative to the implementation of SD in practice on the example of selected municipalities in the Czech Republic. This contribution is examined by a comparative analysis of the indices of change in selected indicators (three to four indicators for each pillar of SD) for municipalities involved in the LA21 initiative in comparison with reference municipalities, which have not been involved in LA21 so far. The analysis results indicate that different trends in some of the indicators can be observed in municipalities implementing LA21 and in the others. This applies, in particular, to the environmental indicators (such as the degree of waste separation, indicating in part the degree of environmental awareness), but also to some of the economic ones (municipal capital expenditures indicating investment activity).     

Global Liquidity,the Private Sector and Debt Sustainability in Sub‐Saharan Africa

This article analyses the effect of changes in international financial markets on the debt dynamics in sub‐Saharan Africa in recent years. A key development is the rise of the private sector as both a lender and a borrower in African debt markets, a process that is associated with the growing integration of the region into global financial markets. The article argues that the Debt Sustainability Framework of the International Monetary Fund and World Bank has taken some steps to account for this growth of private sector, cross‐border debt, but such steps still fall short of what is needed. A full appreciation of the importance of private debt implies, first, that debt sustainability in sub‐Saharan Africa be understood in the context of countries’ integration in global financial markets and the global liquidity cycles that characterize those markets and, second, that the interplay between private and public debt be monitored in order to provide a fuller picture of the impact of private sector debt on fiscal sustainability.     

The Obscured Story of the International Criminal Police Commission,Harry Söderman,and the Forgotten Context of Antiziganism

The Interpol predecessor, the International Criminal Police Commission (ICPC), gradually came under the control of the Nazi Regime. Besides the task of combatting ‘ordinary criminality’, it, since 1934, had ‘combatting of the Gypsy plague’ on its agenda. The Swedish contacts were handled independently by the head of the Swedish forensic institute (SKA), Harry Söderman, who had good contacts with the ICPC presidents Heydrich and Nebe. This essay discusses, from a Swedish perspective but also with an international comparative view, critical and apologetic discourses on the ICPC Nazification and antiziganism. It focuses on available ICPC files at Riksarkivet and their archival surroundings, which lead to the Sandler Commission’s investigation of police collaboration against the Scandinavian sabotage and resistance organization Wollweber. A main conclusion is that the informal network character of the ICPC and its lack of transparency discouraged critical reflections on this Nazification, and, to this day, obstructed a break with antiziganistic police traditions. In contrast to the independent inquiry commissions of Switzerland and Norway, which discuss the context of antiziganism and the ICPC, the selective governmental initiatives in Sweden have until now neglected the topic. The essay also discusses the problematic ICPC source material situation.     

Some Napoleonic-style army camps from the period of the Dutch-Belgian separation (1830–1839) in the Southern Netherlands

This paper focuses on the period of the political separation of the Netherlands and Belgium (1830–1839). Both countries were in a state of war for almost a decade, which resulted in massive troop deployments along their borders and the militarisation of the landscape. The principal objects of study are the Dutch army camps at Rijen and Oirschot near the Belgian border, which to date have barely received any scholarly attention. Both camps were almost 2 km across and offered accommodation to up to 12,000 infantry soldiers. They will be studied from an archaeological-historical perspective, focusing on the spatial and social dimensions of the camps and their place in the wider landscape. The camps are representative of the final stage of pre-industrial warfare in Europe, which is characterised by a continuation of many eighteenth century and Napoleonic traditions.     

WORKINGS OF THE MELTING POT: SOCIAL NETWORKS AND THE EVOLUTION OF POPULATION ATTRIBUTES*

ABSTRACT This paper links the two nascent economic literatures on social networks and cultural assimilation by investigating the evolution of population attributes in a simple model where agents are influenced by their acquaintances. The main conclusion of the analysis is that attributes converge to a melting‐pot equilibrium, where everyone is identical, provided the social network exhibits a sufficient degree of interconnectedness. When the model is extended to allow an expanding acquaintance set, convergence is guaranteed provided a weaker interconnectedness condition is satisfied, and convergence is rapid. If the intensity of interactions with acquaintances becomes endogenous, convergence (when it occurs) is slowed when agents prefer to interact with people like themselves and hastened when interaction with dissimilar agents is preferred.     

Evaluating the Potential of Semi-Automated Image Analysis for Delimiting Soil and Sediment Layers

ABSTRACT

Established methods for delineating anthropogenic and natural strata during fieldwork are based on the visual and tactile perception of excavators. Modern image analysis techniques can help to ensure objectivity and reproducibility when documenting sections and plana. Within this study we examine the unsupervised classification of digital images as a technique for delimiting layers and identifying stratigraphic features. Assessing the potential of this approach, we exemplarily captured soil profiles with high-contrast stratigraphy, located in the area of a historical vineyard (Brandenburg, Germany). Reproducible analyses were carried out using open-source software, allowing for the future advancement of the methodology utilized and providing a basis for the analysis of more complex stratigraphic sequences. We compare clustering results of high-resolution RGB and hyperspectral images (470–830?nm, 37 bands). Multiple pre-processing and processing steps are carried out to evaluate their influence. Our results render the semi-automatic analysis of RGB images helpful for stratigraphic interpretation.
