Discerning geological and geographical sources of Belgian Upper Paleolithic fluorites by rare earth elements and Sr-isotopic geochemistry

Fragments of fluorite (CaF₂) have been found at five Belgian Upper Paleolithic sites (Spy, Chaleux, Trou Magritte, Trou du Frontal and Verlaine caves), primarily of Magdalenian age. These sites are located in a large geographical area. The aim of this study is to isolate one or more primary sources where the mineral could have been quarried prehistorically, and hence try to deduce if time and effort were put into obtaining it, or if it was simply a useful nearby raw material. In order to achieve this objective, isotopic ⁸⁷Sr/⁸⁶Sr and REE ratios are used. A total of four archaeological samples from the Chaleux, Spy and Trou Magritte sites along with geological samples were analyzed (new results and data from the literature), obtained from two distinct stratigraphical units in Belgium: the Givetian limestones (mainly from the Calestian Band), and the Dinantian limestones.     

Dimensions of remapping: Heinrich Schiffers and his mental map of Africa

ABSTRACT

At the beginning of the 1960s, the Athenäum publishing house in Germany planned a revised and extended edition of Heinrich Schiffers’ (1901–1982) successful book Wilder Erdteil Afrika (English translation: The Quest for Africa). The bestselling author had published several monographs about Africa since the 1930s, and authored and edited numerous works after World War II. Nearly all of these works, whose substantial print runs are testament to their popularity, are characterized by an engaging combination of text, images, and cartographic material, creating narratives and mental maps about Africa, its history, and the colonial past. In his later writings, he stressed the importance of “relearning” with regard to Africa and struggled to remap the imaginative geography of Africa. In this paper, I examine the characteristics of Schiffers’ imaginative geography and the change in his writings and maps. I explore whether his concept of “relearning” was an epistemological decolonization or if there were any continuities found in his imaginative geography. In order to grasp the specifics of his thinking, his geography will be briefly compared with that of his contemporary, Frankfurt zoo director Bernhard Grzimek.     

SUBURBAN MUNICIPAL EXPENDITURES: THE EFFECTS OF BUSINESS ACTIVITY,FUNCTIONAL RESPONSIBILITY AND REGIONAL CONTEXT*

A wide variety of models exist seeking to explain variation in the level of suburban government activity. Alternative models stress concepts of local stratification and discrimination, the structure of local decision-making, ecological position, and public choice, each of which suggests varying hypotheses about which suburbs spend more and which less. In this paper we summarize and evaluate the relative strength of each of these alternative models, and propose major directions for future research.
