How flakes shatter: a critical evaluation of quartz fracture analysis

Despite its worldwide use as a stone tool raw material, quartz is known to be a difficult material for archaeologists. The main reason for this is the tendency of quartz flakes to fragment during detachment, which complicates the use of traditional lithic analyses. In this article we present an experimental study of quartz flake fragmentation. We evaluate the method called fracture analysis that has been developed and used explicitly for the study of quartz assemblages. The method assumes high predictability of quartz flake fragmentation, but our experiments show that there is significant variation in fragmentation that fracture analysis does not take into account. Our results indicate that this variation is partly explained by indenter hardness, the relative thickness of the detached flake, as well as individual knapper-related factors. These results undermine the applicability of quartz fracture analysis in its current form. In addition, we discuss the effects of flake fragmentation on the technological organisation of prehistoric quartz users and suggest that it has affected reduction strategies as well as blank and tool dimensions. We also suggest that there should be mobility-related differences in archaeological assemblages in terms of the quality of the quartz raw material and that the curation of quartz should be low in relation to better quality raw materials used parallel with it.     

The Image of the Sámi in Finnish Visual Arts before the Second World War

Abstract

This article examines how Finnish artists depicted the Sámi people in their paintings from the beginning of the nineteenth century to the Second World War. In the first paintings that represented the Sámi, the attitude was very romantic and artists were not interested in knowing the Sámi culture or even in encountering the Sámi people. In the nineteenth century, nationalism required building an image of the Finns, thus most Finnish artists were not interested in the Sámi. The French philosopher Hippolyte Taine's writings influenced the young artist Juho Kyyhkynen, who started to depict the Sámi culture. In the 1920s and 1930s, Sámi were thought to be primitive or Mongolian, so Finnish artists painted relatively few portraits of Sámi. All this time it was only Finnish painters who depicted the Sámi, as the voice and ideas of the Sámi themselves did not become prominent in Finland until the 1970s.     

Frontier Landscape – Lapland in the Tradition of Finnish Landscape Painting

Abstract

Finnish artists depicted Lapland as a frontier. The position of the Lappish landscape as a part of the Finnish landscape painting tradition is explored through a framework based on art and cultural history as well as humanistic and cultural geography. Paintings from three historical periods are analyzed: the early and later period of Finland as an autonomous Russian Grand Duchy (1809–1917), the first decades after the independence of Finland (1917–1939) and the Second World War (1939–1945). Lapland is today the borderline of leisure and work and the frontier of Finnish and Sámi cultures. Earlier Lappish landscapes were places of Sámi nomadism and Finnish farming, which can be seen in the Lappish landscape paintings from the 1890s to 1920s. Finnish art tradition, however, was not ready to accept Lapland, the northern frontier, as a part of Finland. During the 1920s, 1930s and 1940s the meaning of the northern borderline grew and Lapponism, the golden years of Lappish landscape and tourism, began. During the Lapponism period there were few paintings depicting Sámi culture, because the Sámi were thought to be primitive or Mongolian, and were not accepted as part of Finnish culture.     

Social enterprises in regional innovation systems: a review of Finnish regional strategies

The aim of modern innovation policies is to enhance the innovation capability of regions, their organizations and people. Regional innovation system (RIS) theory has been one of the most popular frameworks for realizing innovation policies. Yet, adopting the perspective of sustainable innovation policy where innovation is also seen as a solution to various societal and environmental problems has been slow. Social enterprises (SEs) are discussed here as a means to address those problems, particularly through collaboration between sectors and focusing on social sustainability. The aim of this paper is to identify whether and in what way SEs are communicated as an innovative solution and as a source of innovations for economic and development activities through regional strategies. The data consist of regional innovation and business strategies from all Finnish regions, analysed using qualitative content analysis. We argue that there is a need to go deeper and include effective support mechanisms for SEs in these documents. Better inclusion of SEs as part of innovation systems and communicating this through regional strategies would help to develop SEs and to have them perceived as potential innovators and active entrepreneurial actors in innovation systems contributing to economically, environmentally and socially sustainable development.
