Cave Art in Context: Methods for the Analysis of the Spatial Organization of Cave Sites

Investigations of prehistoric cave art have long neglected the surrounding context: space, archaeological objects, and imprints. As a result, an integrative structural approach that analyzes cave art as part of an anthropomorphized landscape has not been available. This article draws on urban planning and the physiology of the human eye to provide an innovative archaeospatial analysis of cave sites. A set of relevant features from the caves of Bédeilhac, Fontanet, and Le Portel was selected and defined (light zone, chamber type, path network, mode of movement, and available space). An analysis of the prehistoric remains in the caves allows the reconstruction of different concentrations of human activities (cave art, archaeological objects, and imprints). The projection of these concentrations onto the structured map of the caves results in four types of locations: drawing location, supply location, drawing location with substantial activities, and drawing location with consumption activities. This approach opens new avenues for the archaeological perception of caves and their inhabitants: Upper Paleolithic humans were very familiar with caves and probably followed a master plan during their stay in the dark.     

Humans,climate or introduced rats – which is to blame for the woodland destruction on prehistoric Rapa Nui (Easter Island)?

When the first Polynesian settlers arrived on Rapa Nui, about 70% of the island was covered with dense woodland in which Jubaea palms dominated. Our investigations of extended soil profiles provide evidence that more than 16 million palm trees grew on the island. Nearly all palms were removed by the 16th century. Teeth marks on nutshells of the Jubaea palms from the 13th or 14th centuries attest to the activity of Pacific rats (Rattus exulans) on Rapa Nui, which were probably imported there by the first Polynesians settlers. Did the rats perhaps prevent the germination of palm seeds and thus the regeneration of the dense palm woodland of Rapa Nui?     

Networks and Innovation: The Role of Social Assets in Explaining Firms' Innovative Capacity

The claim of a positive association between a firm's social assets and its innovative capacity is a widely debated topic in the literature. Although controversial, such an argument has informed recent innovation policy across Germany, increasingly directed to the cluster formation. In the light of the growing attention and financial efforts that cluster-based innovation policies are receiving, it is worth answering two main questions. First, are firms with a relatively high level of social capital likely to be more innovative? Secondly, do companies pursuing innovation in partnership innovate more? This paper empirically answers these questions by exploring a cross-sectoral sample of 248 firms based in the Jena region. On the one hand, the extent to which a firm is integrated in its community life does not contribute to an explanation of its innovative performance. On the other hand, directed cooperation with the specific goal of innovating shows a positive impact on innovative performance. However, the correlation between the extent of the network of co-innovators and firms' innovative capacity presents an inverted U-shaped relation: there is a threshold in the number of co-innovators justified by the costs of innovating by interacting. A policy lesson can be drawn from these findings: cluster-based policies are to be treated with caution as firms face costs of networking and not merely benefits.     

A real options approach to amenity valuation: The role of uncertainty and risk aversion

Many empirical studies in the fields of urban and environmental economics rely on the hedonic pricing framework. This paper draws attention to two important elements that are not covered by this theory: uncertainty and relocation costs. It develops a theoretical model where agents face uncertainty, but may accumulate savings as a form of self‐insurance. It shows that uncertainty pushes up relocation costs due to the option value of waiting, while self‐insurance helps to reduce this lock‐in problem. Moreover, the model suggests that the implicit price of environmental quality increases with uncertainty even if agents are risk‐neutral.     

Under the Danish Cross: flagging Danishness in the years around World War II

This article explores the significance of the Danish flag in the formation of national identities during World War II and the immediate post-war period. During this dark and tumultuous period of Danish history, the flag was claimed by different groups with very different agendas, which in turn engendered differing conceptions of Denmark and Danishness. Three different themes are investigated in the article. The first regards the flag as a symbol of national continuity and endurance. From this angle, the flag functioned as a living, corporeal piece of history, which signalled that old Denmark would prevail, in spite of the crisis at hand. The second theme investigates the coupling of the flag with democracy during the 1943 elections. This event was hailed by the government as a major national celebration, with nationwide flagging for the democratic values of Denmark. At the same time, the elections were criticized as ‘un-national’, both by home-grown Nazis and the resistance movement. The third section dwells on the notion of martyrdom for the flag. This form of Danishness was not connected to peace-loving democracy, but woven into a martial discourse of sacrifice, honour and masculine heroism. Public worship of martyrdom was particularly intense in the early post-war era, when the flag was used to link ordinary Danes to the fallen heroes of the resistance movement. Thus, it was not the democratic spirit of 1943 that was celebrated after Liberation, but the martyrdom of fallen male resistance fighters, whose blood was evoked as the foundation of the re-born nation. The national memory of post-war Denmark, thereby, was based on the notion of a united people, who had stood firm and even been willing to die for the honour of their ancient flag.
