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.     

Early medieval origins of iron mining and settlement in central Sweden: multiproxy analysis of sediment and peat records from the Norberg mining district

The historical Norberg mining district in central Sweden with its shallow, easily accessible iron ores figures prominently in the earliest documents from the 14th century concerning mining or metallurgy. This 1000-km² district is considered to be one of the first areas in Sweden exploited for iron ores and, in fact, Europe’s oldest known blast furnace, Lapphyttan, is located in the Norberg district about 10 km from the mines in the village of Norberg (Norbergsby). Earlier archaeological excavations suggest the furnace was in operation as early as the 11th or 12th century (870 and 930 ¹⁴C yr BP), and a number of other sites in the district have been dated to the 13th–15th centuries. Here, we have analyzed two lake sediment records (Kalven and Noren) from the village of Norberg and a peat record from Lapphyttan. The Lapphyttan peat record was radiocarbon dated, whereas the sediment from Kalven is annually laminated, which provides a fairly precise chronology. Our pollen data indicate that land use in the area began gradually as forest grazing by at least c. AD 1050, with indications of more widespread forest disturbance and cultivation from c. 1180 at Lapphyttan and 1250 at Kalven. Based on ²⁰⁶Pb/²⁰⁷Pb isotope ratios in Kalven’s varved sediment record, there is an indication of mining or metallurgy in the area c. 960, but likely not in immediate connection to our sites. Evidence of mining and metallurgy increases gradually from c. 1180 when there is a decline in ²⁰⁶Pb/²⁰⁷Pb ratios and an increase in charcoal particles at Lapphyttan, followed by increasing inputs of lithogenic elements in Noren’s sediment record indicating soil disturbance, which we attribute to the onset of mining the iron ore bodies surrounding Noren. From AD 1295 onwards evidence of mining and metallurgy are ubiquitous, and activities accelerate especially during the late 15th century; the maximum influence of Bergslagen ore lead (i.e., the minimum in ²⁰⁶Pb/²⁰⁷Pb isotope ratios) in both Kalven and Noren occurs c. 1490–1500, when also varve properties change in Kalven and in Noren sharp increases occur in the concentrations of a range of other ore-related metals (e.g., arsenic, cadmium, copper, iron, lead, mercury and zinc). From the 15th century onwards mining and metallurgy are the dominant feature of the sediment records.     

Climate in the eastern Mediterranean,and adjacent regions,during the past 6000 years – A review

The eastern Mediterranean, with its long archaeological and historical records, provides a unique opportunity to study human responses to climate variability. We review paleoclimate data and reconstructions from the region with a focus on the last 6000 years. We aim to provide an up-to-date source of information on climate variability and to outline present limitations and future opportunities. The review work is threefold: (1) literature review, (2) spatial and temporal analysis of proxy records, and (3) statistical estimation of uncertainties in present paleoclimate reconstructions (temperature, °C). On a regional scale the review reveals a wetter situation from 6000 to 5400 yrs BP (note: all ages in this paper are in calibrated years before present (i.e. before 1950), abbreviated yrs BP, unless otherwise stated). This is followed by a less wet period leading up to one of fully-developed aridity from c. 4600 yrs BP. There is a need for more high-resolution paleoclimate records, in order to (i) better understand regional patterns and trends versus local climate variability and to (ii) fill the gap of data from some regions, such as the Near East, Greece and Egypt. Further, we evaluate the regional occurrence of a proposed widespread climate event at 4200 yrs BP. This proposed climate anomaly has been used to explain profound changes in human societies at different locations in the region around this time. We suggest that although aridity was widespread around 4200 yrs BP in the eastern Mediterranean region, there is not enough evidence to support the notion of a climate event with rapidly drying conditions in this region.     

Threats to Common‐Pool Resources and the Importance of Forums: On the Emergence of Cooperation in CPR Problem Settings

This paper focuses on cooperation among organizations in a common‐pool resource (CPR) problem situation. Cooperation is particularly challenging in settings where resource degradation is produced by a variety of different sectors and parts of the population; and where the problem, as well as public responsibilities, transcend borders and jurisdictions. Focusing on transboundary water quality management in the Rhine catchment area, we ask: What drives two actors in a CPR problem situation to cooperate with each other? We argue that the degree of threat to a CPR is an important driver for collective action, and focus on actors’ exposure to and perception of a threat to a CPR. Furthermore, we rely on applications of the ecology of games framework (EGF), taking into account the larger institutional context of CPR management. This allows us to test whether actors’ participation in forums, such as regional and international water body associations, helps to overcome the CPR problem by further enhancing interactions among actors. Based on survey data and applying advanced network statistics (exponential random graph models [ERGM]), we conclude that although problem exposure is one factor that enhances joint cooperation, participation in forums plays an even bigger role for cooperation in a CPR problem setting. Our study contributes to research on cooperation in CPR problem settings, highlights the need to more systematically include the effects that CPR problems have on actors when analyzing CPR problem settings, and stresses the function of forums as triggers for cooperation in CPR problem situations.     

The moral geographies of public sector job relocation: discourses of compensation and competence in the Swedish news press

Previous research has pointed to the fact that ideological images of geographies are bound up with the ongoing struggle for economic and social resources, and that moral values and emotions are central in rendering such images intelligible and accepted. To explore this further, we critically engage with the ways in which moral values and emotions contribute to the (re)production of centres and peripheries in the Swedish news press reports of public-sector job relocations. We deploy the discourse theoretical notion of ideological fantasy to critically explain the forces that make particular moral and emotional judgements comprehensible. We identify two discourses in the news press material – one about competence and one about compensation – built up by morally and emotionally charged articulations. We argue that ideological fantasies worked as driving forces both in this moral and emotional news debate and also in the ongoing constitution of geographies.     

Rats cannot have been intermediate hosts for Yersinia pestis during medieval plague epidemics in Northern Europe

The commonly accepted understanding of modern human plague epidemics has been that plague is a disease of rodents that is transmitted to humans from black rats, with rat fleas as vectors. Historians have assumed that this transmission model is also valid for the Black Death and later medieval plague epidemics in Europe. Here we examine information on the geographical distribution and population density of the black rat (Rattus rattus) in Norway and other Nordic countries in medieval times. The study is based on older zoological literature and on bone samples from archaeological excavations. Only a few of the archaeological finds from medieval harbour towns in Norway contain rat bones. There are no finds of black rats from the many archaeological excavations in rural areas or from the inland town of Hamar. These results show that it is extremely unlikely that rats accounted for the spread of plague to rural areas in Norway. Archaeological evidence from other Nordic countries indicates that rats were uncommon there too, and were therefore unlikely to be responsible for the dissemination of human plague. We hypothesize that the mode of transmission during the historical plague epidemics was from human to human via an insect ectoparasite vector.     

Impacts of Market Liberalization on Regulatory Network: A Longitudinal Analysis of the Swiss Telecommunications Sector

This article looks at the reconfiguration of the regulatory actors' network, as induced by the liberalization and reregulation processes in utility sectors. It investigates the changes in governance structures and patterns of collaborative ties between actors resulting from these processes. Applying stochastic actor‐oriented modeling (SAOM) to data on the liberalization of the Swiss telecommunications sector over two decades, we test whether and to what extent structural changes driven by liberalization and reregulation express themselves through network effects, that is, through changing patterns of interactions between political authorities, regulators, regulatees, and interest groups. Our empirical tests highlight a rearrangement of the regulatory network and a reorganization of relational patterns around new actors, such as the sector‐specific regulatory agency, coregulators, and new operators.     

Sebbersund: isotopes and mobility in an 11th−12th c. AD Danish churchyard

The important Viking Age and early Medieval site of Sebbersund in northern Jutland, Denmark, contains a large churchyard from the 11th–12th century AD. Sebbersund was an important trading center in this period and the location of one of the first churches in Denmark, perhaps an entry point for the introduction of Christianity to the country. Excavations have exposed almost 500 graves of an estimated 700 individuals in the cemetery. Here we report on the analysis of strontium isotopes in human tooth enamel from burials in the cemetery as a signal of place of birth. Some 19 samples have been measured and at least three non-local outliers identified. Futhermore, six archaeological fauna samples had been analyzed in order to define the local bioavailable strontium isotope baseline range and these values were compared to the more general bioavailable baseline range values for Denmark. The burials are evaluated in light of the available archaeological, chronological, anthropological, and isotopic information.     

Confrontation and conciliation: the sami,the crown and the court in seventeenth-century swedish lapland1

This article aims to discover in what kind of legal cases conflicts may be traced between the Sami and representatives of the Crown, and in which situations conciliation is apparent; and it also answers the questions of how and why this happened. It is evident, from the court rolls from the court district of Jukkasjärvi (one of the two northernmost lappmarker in Sweden at this time), that the Crown prosecuted the Sami for sexual offences and crimes against religion. This was due to the prevailing ideology of the seventeenth century, in which Lutheran Christianity prevailed, and because the court was the arena for a power discourse: there was a “right” way to live and behave. This came into conflict with Sami tradition. The Sami themselves pursued a desire and need for conciliation, which becomes apparent in cases of crimes such as murder, manslaughter and grand theft, but also in civil cases, e.g. inheritance. This was due to the fact that the population was quite small, bound together in different relations, and because large-scale conflicts were not beneficial to Sami communities. Even though the Crown Court was an arena of power, it was also used by the Sami for their own ends, and thus we can see an interactive Sami society, independent of the prevailing political Lutheran Christian ideology and its discourse.
