Pigments, dyes, and black enamel—the colorants of reverse paintings on glass

Nondestructive analyses of medieval reverse paintings on glass revealed the same dyes and pigments customarily used in panel paintings. However, there is one exception: the black colorant is not a carbon-based pigment, but black enamel. In this respect, the stylistic as well as the technical influence of stained glass artwork can clearly be seen on reverse paintings on glass. However, there is a crucial difference: in reverse paintings, the black enamel is not fired onto the glass but painted (cold painting). Additional analyses confirmed these findings. Based on these results, the art form “reverse painting on glass” has technically to be characterized as a mixture of “stained glass” and “panel painting” that nonetheless develops into a genre of its own.     

The 2010 independence jubilees: the politics and aesthetics of national commemoration in Africa

In 2010, as many as seventeen African states celebrated their independence jubilees. The debates surrounding the organisation of these celebrations, and the imagery and performances they employed, reflect the fault lines with which African nation‐building has to contend, such as competing political orientations as well as religious, regional and ethnic diversity. The celebrations represented constitutive and cathartic moments of nation‐building, aiming to enhance citizens' emotional attachments to the country and inviting to remember, re‐enact and re‐redefine national history. They became a forum of debate about what should constitute the norms and values that make‐up national identity and, in the interstices of official ceremonies, provided space for the articulation of new demands for public recognition. A study of the independence celebrations thus allows us to explore contested processes of nation‐building and images of nationhood and to study the role of ritual and performance in the (re)production of nations.     

Decentralization,the State and Conflicts over Local Boundaries in Northern Ghana

Decentralization projects, such as that initiated by the Rawlings government in Ghana at the end of the 1980s, create a political space in which the relations between local political communities and the state are re‐negotiated. In many cases, the devolution of power intensifies special‐interest politics and political mobilization aiming at securing a ‘larger share of the national cake’, that is, more state funds, infrastructure and posts for the locality. To legitimate their claims vis‐à‐vis the state, civic associations (‘hometown’ unions), traditional rulers and other non‐state institutions often invoke some form of ‘natural’ solidarity, and decentralization projects thus become arenas of debate over the boundaries of community and the relationship between ‘local’ and national citizenship. This article analyses one such debate, in the former Lawra District of Ghana's Upper West Region, where the creation of new districts provoked protracted discussions, among the local political elite as well as the peasants and labour migrants, about the connections between land ownership and political authority, the relations between the local ethnic groups (Dagara and Sisala), and the relevance of ethnic versus territorial criteria in defining local citizenship.     

Tikal timbers and temples: ancient Maya agroforestry and the end of time

Tikal, a major lowland Maya civic-ceremonial center in the heart of the Petén region of Central America, relied heavily on the adjacent lowland rainforest as a resource base for fuel and construction materials. In this study, we analyzed 135 wood samples from timbers used in the construction of all six of the city's major temples as well as two major palaces to determine which tree species were being exploited and to better understand ancient Maya agroforestry practices during the Late Classic period. We found evidence for a change in preference from the large-growing, upland forest species, Manilkara zapota, to a seasonal wetland species Haematoxylon campechianum in A.D. 741 as well as a decrease in lintel beam widths over time. Though M. zapota later returned as the wood species of choice in A.D. 810, beam widths were found to be significantly smaller. These findings concur with models that hypothesize widespread deforestation during the Late Classic period and indicate a declining forest resource base by the 9th century A.D. Because of the many large timbers available for temple construction in the 8th century, some system of forest conservation is indicated for the ancient Maya prior to the Late Classic period.     

New evidence for jute (<Emphasis Type="Italic">Corchorus capsularis</Emphasis> L.) in the Indus civilization

In this paper, we report the results of an analysis of a preserved structure of jute on a ceramic artifact from the site of Harappa that is dated to 2200–1900 (cal.) BC (Fig. 1). Jute cloth has not previously been identified at this early date in the Indus civilization. Since fiber remains are rare in prehistoric South Asia, we briefly review the evidence for seed and fiber remains used in textile production in this region.     

Was bedeutet “Entschuldigung”? Die Überlebenden medizinischer NS‐Verbrechen und die Max‐Planck‐Gesellschaft

The Meaning of “Apology”: The Survivors of Nazi Medical Crimes and the Max Planck Society. Around the turn of the twenty‐first century a new practice in international politics became established: representatives of political, economic and religious organisations apologised for the historical and political crimes of their own collectives, addressing the victims or the victims' descendants. At a public event in Juni 2001, a formal apology of this kind was made by the president of the Max Planck Society (MPS), who had previously launched an extensive programme of research into the National Socialist history of what was then the Kaiser Wilhelm Society. The majority of the eight invited survivors of human experimentation in Nazi concentration camps refused forgiveness. Instead, they called for the MPS not to content itself with historical research and analysis, but to ensure the continued remembrance of the victims and their suffering. Starting from this 2001 ritual of repentance, the paper examines the participants' diverse views of how to deal with the medical crimes of National Socialism, and asks about possibilities of going beyond historical retrospection to fulfil the imperative of remembrance.     

The Invisible Hand that Rocks the Cradle: On the Limits of Time Use Surveys

Almost every intervention in the field of international agricultural development — from microcredit finance to fertilizer subsidies to trade policy — has come to recognize gender, and relationships within households, as important. Yet most interventions continue to treat the household as a ‘black box’, with changes within the household measured by the effects on income, anthropometry, health, or other secondary metrics within bargaining models. In this context, there has been increasing interest in time use studies as a way to peer inside this black box. This article offers a review of methods and identifies some of the difficulties facing time use studies in capturing intrahousehold dynamics, and presents the results of a two‐season simultaneous activity time use study in Malawi which aimed to address these difficulties. The results suggest significant limitations to time use surveys. The kinds of reproductive labour that often interest researchers may be invisible to the women responding to time use surveys, with the result that care work is dramatically under‐reported. The authors discuss the implications of the divergence between researchers’ concerns and the women's reports of their lives for time use surveys, and for feminist development research methods more broadly.     

Performing the national territory: The geography of national‐day celebrations

The nation is a relatively abstract imagined community that is visualised through a variety of symbols as well as communicative and performative practices. In this paper, we explore how the national territory, one of the foundations of the nation‐state, is performed on national‐day celebrations and brings the nation into being. Drawing on ethnographic research on national days in Burkina Faso, Côte d'Ivoire and Ghana, we show how the state's internal administrative divisions and ethnic differences are at once made explicit but also subordinated to the nation. Moreover, we show how in such celebrations, potentially disruptive or competing affiliations such as ethnicity and regional loyalties are re‐imagined. Both the rotation of the central celebration and its replication all over the national territory carry the nation into the regions and integrate the regions into the nation‐state. The ‘co‐memoration’ turns participants and spectators from locals into national compatriots and thus not only performs nationality but also performs the relationship among nation, state and citizen, set within a particular territory.
