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.

‘Old wood’ effect in radiocarbon dating of prehistoric cremated bones?

Numerous reports of successful radiocarbon dating of cremated bones have emerged during the last decade. The success of radiocarbon dating cremated bones depends on the temperature during burning and the degree of recrystallisation of the inorganic bone matrix. During cremation bones undergo major morphological and mineralogical changes which have raised some interesting questions and discussion on the origin of the carbon source in archaeologically cremated bones. Recent laboratory experiments reveal that the properties of the combustion atmosphere play a significant role regarding the source carbon in cremated bones. Thus radiocarbon dating cremated bones is potentially dating the wood used for the cremation fire. Here we compare a high precision radiocarbon dated human bone with an associated dendrochronological age from an oak coffin. We find that the age discrepancy between the dendrochronological age and the cremated bone of 73 ± 26 ¹⁴C yr is best accounted for by the so called ‘old wood’ effect.     

Faecal biomarker and archaeobotanical analyses of sediments from a public latrine shed new light on ruralisation in Sagalassos, Turkey

A public latrine in the ‘Imperial Baths’ of Sagalassos was transformed into a dump site in the early Byzantine period. Several layers of urban waste, including ceramics, bones, glass and perhaps excrements were deposited on the floor. Faecal biomarker analyses and archaeobotanical analyses were conducted to reconstruct the history of the room. 5β-stanols of human origin, such as coprostanol, were found in the sewage channels together with mineralised plant remains, indicating a human faecal context. The botanical remains are furthermore representative of the Roman diet of the Sagalassians. Soil layers, deposited on top of the latrine floor and dating to the early Byzantine period, contained herbivore derived 5β-stanols, such as 5β-stigmastanol and epi-5β-stigmastanol. Additionally, a clear predominance of epi-5β-stanols over 5β-stanols showed that the animal dung has been subject to composting. In this period, the former latrine was clearly used as a manure production site which is further confirmed by stratigraphic evidence of large amounts of urban waste artefacts, which were commonly collected together with manure before application on the fields. The results of the present study support the theory that off-site potsherd scattering can be used as a proxy for manuring events. Additionally, the data show key evidence for vertical migration of 5β-stanols and presumably also for the leaching of bile acids.
