Comparing the survival of osteocalcin and mtDNA in archaeological bone from four European sites

The small mineral-binding bone protein, osteocalcin, has been applied in a number of studies on ancient bone due to predictions of its long-term stability. However, the intact protein has not been shown to survive in ancient bone devoid of DNA, which is a much more phylogenetically informative biomolecule. In this investigation, the survival of osteocalcin is directly compared to the amplification of mtDNA in a set of 34 archaeological samples from four sites throughout Europe. We also present unpublished osteocalcin sequences of seven mammalian species in addition to the 19 published sequences to highlight phylogenetic limitations of this protein. The results indicate that the intact osteocalcin molecule survives less in archaeological samples than mtDNA and is more subject to the temperature of the archaeological site. Amino acid analyses show the persistence of the dominant protein collagen in samples that failed both osteocalcin and mtDNA analyses. The implications these findings present for biomolecular species identification in archaeological and palaeontological material are that, although proteins do survive beyond ancient DNA, osteocalcin does not appear to be the most ideal target.     

Playing with Flint: Tracing a Child’s Imitation of Adult Work in a Lithic Assemblage

This paper examines the potential for identifying play and children’s imitation in the archaeological record and reviews cultural constructions of play and cross-cultural behaviour. A case study, using a lithic assemblage from a discrete knapping area for Scandinavian Neolithic axe production in Southern Sweden which identifies a child’s activity area, is discussed. The theoretical and methodological assumptions behind play, imitation and its identification as well as its social implications are also examined.     

Job polarization in the new economy in Danish cities: location,size, and the role of the public sector

ABSTRACT

In this paper we examine the geographic patterns of employment growth and employment polarization in small and medium-sized cities (SMCs) in Denmark during the rise of the new economy. The geography of employment polarization in Danish cities is examined using register-based employment data on occupations and wages divided into the public and private sectors in the period 1993–2006; it therefore covers a long period of transformation and growth in the Danish economy. We conclude that employment growth is characterized by employment polarization combined with growth in low- and high-wage employment and a decline in medium-wage employment. However, these patterns of polarization differ across the public and private sectors, as well as by geography. While local labour market (LLM) size, city position and city specialization influence the geography of private-sector employment growth and polarization, municipal population and composition influence the geography of public-sector growth patterns across wage levels. Finally, public and private employment are positively associated within SMCs, predominantly driven by the positive association between public employment and private-sector low-wage employment. However, public employment is not associated with an increase in private low-wage employment in more remote areas.     

COMMODIFYING DANISH HOUSING COMMONS

Housing was a backbone of the Danish welfare state, but this has been profoundly challenged by the past decades of neoliberal housing politics. In this article we outline the rise of the Danish model of association‐based housing on the edge of the market economy (and the state). From this, we demonstrate how homes in private cooperatives through political interventions in the context of a booming real estate market have plunged into the market economy and been transformed into private commodities in all but name, and we investigate how non‐profit housing associations frontally and stealthily are attacked through neoliberal reforms. This carries the seeds for socio‐spatial polarization and may eventually open the gate for commodification – and thus the dismantling of the little that is left of a socially just housing sector. Yet, while the association‐based model was an accessary to the commodification of cooperative housing, it can possibly be an accomplice in sustaining non‐profit housing as a housing commons.     

REGIONALIZING “MODE 2”? THE ADOPTION OF CENTRES OF EXCELLENCE IN SWEDISH RESEARCH POLICY

This article contributes to the ongoing debate on the role of university research for innovation and economic growth, a debate highly influenced by concepts such as Mode 2 and regional innovation systems and clusters. A prominent trend in many EU and OECD countries is to direct research funding towards so‐called Centres of Excellence (CoEs) in order to stimulate the industrial output of scientific research. The implementation of the CoE approach is viewed as an attempt to bridge research and innovation policy. By using Sweden as an example and providing an overview and critical discussion concerning Swedish research policy during the period 2001 to 2007 we show that the rhetoric within research policy has changed and become increasingly intertwined with innovation policy. In practice, however, this is not as evident. The study draws on (a) an analysis of policy literature pointing out regulatory and organizational changes concerning the increasing emphasis on linking research to competitive industrial milieus, and (b) a comprehensive database including 110 CoEs, presenting a detailed picture of university‐industry collaboration, cross‐disciplinarity, and prioritized sectors. We fiind that the CoEs account for a relatively small share of government funding, but may however have a strengthening impact on particular research milieus and industries, especially in the life sciences. Additionally, although contemporary policy rhetoric appears to highlight steering funding to geographically‐concentrated milieus, thereby linking leading university research to regional industrial clusters, this has only been manifested in a few cases – notably in the Vinnväxt programme run by Vinnova, the national agency promoting innovation systems.
