Establishing collagen quality criteria for sulphur isotope analysis of archaeological bone collagen

Sulphur isotope measurements of bone collagen from archaeological sites are beginning to be applied more often, yet there are no clear criteria to assess the quality of the collagen and therefore the validity of the sulphur isotope values. We provide elemental data from different methods (DNA sequences, amino acid sequences and mass spectrometric measurements) which are used to establish a reliable system of quality criteria for sulphur isotope analyses of bone collagen. The difference in the amount of sulphur from fish and mammalian collagen type I led to the suggestion to use different criteria to assess the in vivo character of the collagen between these two categories. For establishing quality ranges, the bone collagen of 140 modern animals were analysed. The amount of sulphur in fish and mammalian bone collagen is 0.63 ± 0.08% and 0.28 ± 0.07%, respectively. Based on these results we define for mammalian bone collagen an atomic C:S ratio of 600 ± 300 and an atomic N:S ratio of 200 ± 100, and for fish bone an atomic C:S ratio of 175 ± 50 and an atomic N:S ratio of 60 ± 20. These quality criteria were then applied to 305 specimens from different archaeological contexts.     

Research and Activism in Sámi Politics: The Ideas and Achievements of Karl Nickul towards Securing Governance for the Sámi

Abstract

Pacifist, land surveyor, friend of the Sámi people, scholar studying Sámi culture, Karl Nickul's (1900–1980) life work proves that the work of a public servant and researcher can be merged into a strong ethical stand to influence society. Nickul, an early initiator of Finland's peace movement, was by training and profession a land surveyor, who worked for the Finnish government making maps of Lapland and Petsamo in northern Finland in the 1920s and 1930s. Becoming acquainted with the Skolt Sámi, he began to study them and to take part in the official discussions about their status. With a project to preserve Skolt culture Nickul's paramount idea of Sámi governance began to grow. He actively pursued this idea after World War II through his activities in Sámi politics in Finland and in Sámi cooperative efforts in the Nordic countries. The dominant idea was that the Sámi culture was to be protected from outside pressures of settlement, and that the Sámi themselves should be allowed to determine their own identity and their own needs. The paper discusses and analyses Karl Nickul's personal development and involvement in various projects and activities to secure Sámi rights.     

“I do not know if Mum knew what was going on”: Social reproduction in boarding schools in Soviet Lapland

ABSTRACT

This inquiry into the history of boarding schools for indigenous and quasi-indigenous, tundra-connected children in the Soviet part of Lapland tries to answer why children were sent to a boarding school despite their parents living in the same village, and also why an additional school for mentally disabled children, a school half as big as the boarding school for “regular” children, was opened. Data from oral history interviews among former pupils and teachers, both indigenous and incomers, are combined with archival materials. Using the concepts of cynical knowledge as well as the Bourdieuan notions of social exclusion and reproduction, concealed functions of the boarding school system are identified, among which are the attenuation of housing shortage and the operation of the school out of economic interests, alongside with ethnocentric and paternalist patterns. The stigmatization of mostly Sámi children from relocated families as mentally disabled is set in a frame of individualization of the negative, which sought to present failures of the state’s social engineering as personal fallibility.
