Management skills for artists: ‘learning by doing’?

Although artists must usually be self‐reliant when managing their business, an artist’s education typically concentrates on artistic skills rather than managerial knowledge. This paper analyses the current curricula of 154 art institutions (public and private), focussing on the so‐called DACH countries (Austria, Germany and Switzerland). The results show a deficit in the implementation of economic and, especially, business‐related topics in the education of artists at art universities and institutions. A glimpse at Anglo‐American countries shows that, unlike in Europe, art schools are more open‐minded about implementing economic content into their curricula.     

Patterns of Diagenesis in Bone II: Effects of Acetic Acid Treatment and the Removal of Diagenetic CO3

Archaeological bones of varying preservation have been treated with 0·1 M acetic acid in order to investigate the effect on structural and chemical alterations caused by diagenesis. Acetic acid is commonly used as a “cleaning agent” for removing diagenetic carbonate from bone and enamel, in an attempt to recover original, biogenic signals for use in dietary and¹⁴C dating studies.Diagenetic parameters were measured before and after treatment on a range of archaeological bones with good and bad preservation. Histological preservation defined the behaviour of the correlating parameters, where correlation coefficients between carbonate content and crystallinity, microporosity and macroporosity increased significantly after treatment. For histologically well preserved material, acetic acid is effective at returning carbonate content to around that of modern bone. Where bone is extensively damaged by micro-organisms, “loose” diagenetic material can be removed, but a fraction largely composed of hypermineralized bioapatite remains, which, we believe, cannot be reliably used to obtain accurate biological signals.     

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.

Maize,beans and the floral isotopic diversity of highland Oaxaca,Mexico

Oaxaca, Mexico has been inhabited by humans for over 10,000 years. From the time of earliest habitation, this environment provided a wide floral subsistence to its human inhabitants, notably documented at the cave site of Guila Naquitz. Light stable isotopes, primarily carbon and nitrogen, have been used in dietary and environmental reconstructions throughout Mexico and Central America. We report a large isotopic study of wild and market plants from Oaxaca that demonstrates 1) overlapping δ¹³C values of C4 plants, including maize, and plants that utilize the Crassulacean Acid Metabolism (CAM) pathway for biosynthesis, 2) the existence of a significant C4 grass biomass, 3) the lack of isotopic separation in the δ¹⁵N of legumes and non-leguminous plants and 4) the increase in the nitrogen isotopic composition of crop plants relative to wild plant averages. These four observations are potential complicating factors in interpretations involving the origins and spread of maize agriculture, the relative amount of maize in the diet and assessments of trophic level or meat contributions to the human diet.
