Uniform Pricing Versus Mill Pricing

This paper analyzes the coexistence of different pricing strategies. The purpose is to discuss how firms that are limited to uniform pricing affect the outcome of price competition among mill–price–setting firms. Price competition among (three) firms that are restricted to mill pricing is analyzed within the classic Hotelling framework and uniform–price–setting firms are considered as first movers. If uniform–price–setting firms deliver any good, they effectively separate mill–price–setting firms from each other. Finally, it is shown that price competition among first movers strengthens the effects of cross–type price competition.     

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.     

The crisis before the crisis: the ‘problems of modern society’ and the OECD, 1968–74

‘Economic crisis’ is conventionally understood as the absence of economic growth. However, far from being straightforward and self-explanatory, this understanding is itself an expression of a very particular ensemble of statistical techniques, economic theory, state practices and broader societal beliefs; it is not adequate for the historical analysis of what people have historically perceived as economic crises. This article aims at illustrating this divergence by analysing debates within the Organisation for Economic Cooperation and Development (OECD) on the so-called ‘problems of modern society’ from 1968 to 1974. These problems, which occurred at a time of comparatively robust economic performance, were perceived by contemporaries as a crisis closely related to the economic system. This debate led to a new impetus to recast the formerly dominant quantitative-growth paradigm in terms of environmental policies and qualitative growth. It was spearheaded by critical intellectuals within the OECD Secretariat and the OECD's Committee on Science and Technology Policy, who were at the same time launching the Club of Rome. In this article I will draw out the main arguments, actors, relevant contexts and effects of this discussion to highlight some of the characteristics of the intellectual uncertainty so distinctive of this period. The author argues that a historical understanding of this ‘crisis before the crisis’ demands a broader conception of economic crisis, one that is able to grapple with the divergence of economic growth, human welfare and environmental sustainability.     

First results of metallographic analysis and absolute dating of iron finds from Nowe Brzesko,site 26, Proszowice District

This paper presents the results of analyses of metal artefacts discovered at a multiphase site in Nowe Brzesko, Małopolskie Voivodeship, Poland. Fieldwalking prospection led to the discovery of steely iron objects, ploughed out on the site among other numerous archeological finds. A prospecting sondage yielded more corroded metal artefacts, identified mainly as agricultural tools (e.g. sickles, scythes). These chronologically nondistinctive artefacts could be assigned to the third to fourth century AD using radiocarbon dating, complemented by metallurgical analysis. The results open up new research perspectives on the economy and society of the Przeworsk culture in the Late Roman period.     

A Balancing Act: Domestic Pressures and International Systemic Constraints in the Foreign Policies of the Great Powers, 1848-1851

During the revolutions of 1848 and their aftermath, the governmentsof France, Austria and Prussia, respectively, were exposed toextraordinary pressure from a variety of nationalist movementswith fundamentally different agendas. They had difficult choicesto make as to whether they let their foreign policies be determinedby domestic concerns or heed the rules of the internationalsystem—it was hardly possible to do both. As a resultthey performed a ‘balancing act’ on a tight rope:a wrong step could cause their fall, either because they wouldbe overthrown by their own people, or they would risk war withother Great Powers. Those not affected by a revolution in 1848,i.e. conservative Russia and progressive Britain, had to opteither for backing countries with political tendencies similarto their own, or for simply upholding the balance of power andinternational rules. The author concludes that the ‘primacyof foreign policy’—within this context more preciselythe primacy of the international system's rules and the balanceof power—helps to understand the actual foreign policiesof four of the five Great Powers during the European crisisof 1848–51. Austria's government, the one country tryingto overthrow the balance of power and change the nature of thesystem, was effectively checked. The rules of the post-1815international system were still an efficacious tool for discipliningstates.     

Climate as resource and challenge: international cooperation in the UNESCO Arid Zone Programme

ABSTRACT

Perceptions of climatic challenges have changed significantly during the twentieth century. In recent decades, the question of global climate change received more attention than regional climatic challenges and the problems of arid regions. Historians have shown that persistent misconceptions and a lack of understanding of arid zones rooted in misguided colonial ideologies were propagated by United Nations (UN) initiatives such as the UNESCO (United Nations Educational, Scientific and Cultural Organization) Arid Zone Programme. Alarmist narratives of progressive desertification proliferated and put the blame on destructive local practices such as deforestation and overgrazing. This article investigates UNESCO’s interests in natural resources (section 1) and takes a closer look at the development and scientific elements of the Arid Zone Programme (sections 2 and 3). It argues that the Arid Zone Programme offered an effective framework that helped develop and spread new interdisciplinary research approaches to improve knowledge about arid zones. The myth of progressing desertification and misguided colonial expertise characterized much of its political rhetoric, but not its scientific work, which reflected balanced and more critical appraisals of out-dated colonial expertise. In its conclusion, the article suggests that broader contexts need to be taken into account to understand a resurgence of alarmist narratives of desertification such as shifting interests in climatology from local climatic issues to the global atmospheric circulation and a neglect of the climatology of arid zones.
