An alternative interpretation of the Ediacaran (Precambrian) chondrophore Chondroplon Wade

The genus Chondroplon, known from only 2 specimens worldwide, is re-interpreted as a deformed Dickinsonia.     

Oaks,tree-rings and wooden cultural heritage: a review of the main characteristics and applications of oak dendrochronology in Europe

We overview the recent development of oak dendrochronology in Europe related to archaeology and art-history. Tree-ring series of European oaks (Quercus robur and Q. petraea) have provided a reliable framework for chronometric dating and reconstruction of past climate and environment. To date, long oak chronologies cover almost the entire Holocene, up to 8480 BC and the network over the entire area in which the two oaks grow is being improved. We present the main characteristics of oak ring series and discuss the latest methodological advances in defining the calendar year in which the tree-rings were formed and in interpreting such dating in terms of the age of a wooden object. Dendrochronology has established itself as a standard dating tool and has been applied in a wide variety of (pre-)historical studies. Archaeological wood, historical buildings, works of art (such as panel paintings and sculptures) have been successfully investigated. Recent advances in dendro-provenancing have helped to obtain more information on the timber trade in the past. Information on past forest structures, silviculture and timber use have become available through scrutinizing historical and contemporary ring-width patterns.     

Ancient bacterial DNA (aDNA) in dental calculus from archaeological human remains

The purpose of this study was to identify reactive bacterial aDNA in archaeological human dental calculus. Dental calculus was collected from a middle/late Neolithic human skull from Hulbjerg passage grave, Langeland, Denmark and prepared for transmission electron microscopy (TEM) or gold-labeled antibody TEM. TEM showed calcified, as well as non-calcified bacteria. Immunogold labeling occurred over the cytoplasmic portions of the sectioned bacteria. The result demonstrated that it is possible to identify aDNA sequences from bacteria in archaeological material of considerable age by this technique.     

“‘Ruottiksi’, translated Paul Muotka patiently. ‘Kiitos.’” Mikael Niemi,Meänkieli and Readers Inside and Outside Tornedalen

The present study in the research field of literary multilingualism and literary codeswitching is based on Mikael Niemi's novel Mannen som dog som en lax (2006) [The man who died like a salmon]. The novel is set mainly in Tornedalen, a widely bilingual area in Sweden where many people speak both Swedish and Meänkieli, a national minority language in Sweden since 2000. All instances of codeswitching in the material studied were identified and an analysis, based on Eriksson and Haapamäki's model designed to analyse literary multilingualism and literary codeswitching, was performed. The model consists of three main components: (1) the communicative context of the analysed work; (2) the form of codeswitching in the analysed work; and (3) the possible literary functions of codeswitching in the analysed work. The sender, Mikael Niemi, does not consider himself bilingual and most intended receivers are not bilingual either, even though linguistic conditions are central to the theme of the novel. Swedish is the base language of the novel, while elements of Meänkieli/Finnish, varieties of Swedish, and other languages represent a small fraction of the entire text. Implicit literary codeswitching predominates in the material in the form of metalinguistic comments and contextualization cues. By far the most common type of explicit literary codeswitching is between Swedish and Meänkieli/Finnish. The novel contains examples of literary codeswitching used in attempts to reproduce authentic usage and depict an authentic linguistic setting. In other examples, Tornedalen, Tornedalians and Meänkieli/Finnish are depicted as exotic phenomena compared with the majority society. Likewise, there are examples of how certain passages in the novel may include or exclude readers, depending on their understanding of Meänkieli/Finnish. Certain elements of Meänkieli can be interpreted as expressions of linguistic emancipation and the liberation of identity that empowers speakers of Meänkieli and the community of these speakers.     

DETERMINANTS OF IMMIGRANTS’ ENTRY TO HOMEOWNERSHIP IN THREE NORDIC CAPITAL CITY REGIONS

The extent of homeownership among immigrants may be seen as an indicator of integration and as a determinant of ethnic residential segregation. Studies have shown differences in the determinants of homeownership between immigrants and natives, indicating that variation in homeownership is not only a function of differences in economic resources. These studies have largely focused on Anglo‐American contexts, using mostly cross‐sectional data. We apply survival analysis methods to analyse the determinants of entry to homeownership in the capital regions of three Nordic countries – Denmark, Finland and Sweden – utilizing longitudinal individual‐level register‐based datasets. We find that differences in entry to homeownership between natives and different immigrant groups cannot be explained by differences in socio‐economic background factors. We also find differences in the effects of these factors. Effects of income are generally weaker among non‐Western immigrants and immigrants are less responsive to changes in household composition. The share of non‐Western immigrants in the neighbourhood is only weakly related to entry to homeownership, while immigrants and natives living in public rental housing tend to be slightly less inclined to move to homeownership. Weaker income effects among immigrants, weak effects of ethnic segregation and the importance of the public rental sector differentiate our results from earlier findings. Weaker income effects may indicate that uncertainty about the future also affects middle‐income immigrants. Differences between the three contexts in housing markets and policies do not seem to matter much, although the results indicate that difficult access to the private rental sector may push immigrants to homeownership.     

Seasonality of human site occupation based on stable oxygen isotope ratios of cod otoliths

Oxygen isotope ratios (δ¹⁸O) were measured in micromilled samples of cod otoliths recovered from two Stone Age sites, one from Skoklefald, southeastern Norway and five from Skipshelleren, southwestern Norway. Discrete samples of otolith material were milled from the edge of the otolith towards the centre, each sample representing 3–4 weeks of growth. The δ¹⁸O values showed seasonal signals, covering a period 1–2 years prior to the time of capture. Isotope ratios at the edge of the otoliths, which is the material deposited at the time of fish capture, corresponded to the coldest seasonal water temperatures, in late winter or early spring. These data provide independent evidence for the season of use of the Skoklefald and Skipshelleren sites.
