Negotiating the North

This book brings together the cumulative results of a three-year project focused on the assemblies and administrative systems of Scandinavia, Britain, and the North Atlantic islands in the 1st and 2nd millennia AD. In this volume we integrate a wide range of historical, cartographic, archaeological, field-based, and onomastic data pertaining to early medieval and medieval administrative practices, geographies, and places of assembly in Norway, Sweden, Denmark, Iceland, the Faroe Islands, Scotland, and eastern England. This transnational perspective has enabled a new understanding of the development of power structures in early medieval northern Europe and the maturation of these systems in later centuries under royal control. In a series of richly illustrated chapters, we explore the emergence and development of mechanisms for consensus. We begin with a historiographical exploration of assembly research that sets the intellectual agenda for the chapters that follow. We then examine the emergence and development of the thing in Scandinavia and its export to the lands colonised by the Norse. We consider more broadly how assembly practices may have developed at a local level, yet played a significant role in the consolidation, and at times regulation, of elite power structures. Presenting a fresh perspective on the agency and power of the thing and cognate types of local and regional assembly, this interdisciplinary volume provides an invaluable, in-depth insight into the people, places, laws, and consensual structures that shaped the early medieval and medieval kingdoms of northern Europe

Making touch-based kiosks accessible to blind users through simple gestures

Touch-based interaction is becoming increasingly popular and is commonly used as the main interaction paradigm for self-service kiosks in public spaces. Touch-based interaction is known to be visually intensive, and current non-haptic touch-display technologies are often criticized as excluding blind users. This study set out to demonstrate that touch-based kiosks can be designed to include blind users without compromising the user experience for non-blind users. Most touch-based kiosks are based on absolute positioned virtual buttons which are difficult to locate without any tactile, audible or visual cues. However, simple stroke gestures rely on relative movements and the user does not need to hit a target at a specific location on the display. In this study, a touch-based train ticket sales kiosk based on simple stroke gestures was developed and tested on a panel of blind and visually impaired users, a panel of blindfolded non-visually impaired users and a control group of non-visually impaired users. The tests demonstrate that all the participants managed to discover, learn and use the touch-based self-service terminal and complete a ticket purchasing task. The majority of the participants completed the task in less than 4 min on the first attempt

Climate and societal impacts in Scandinavia following the 536 and 540 CE volcanic double event

In the Northern Hemisphere, the mid-6th century was one of the coldest periods of the last 2000 years, as indicated by both proxy records and Earth System Model (ESM) simulations. This cold period was initiated by volcanic eruptions in 536 CE and 540 CE. Evidence from historical sources, archaeological findings, and proxy records suggests that the extent and severity of this volcanic induced cooling was spatially heterogeneous and that the effect on society resulted in adaptation and resilience at some locations, whereas social crisis has been indicated at others. Here, we study the effect of the volcanic double event in 536 CE and 540 CE on the climate and society in Scandinavia with a special focus on Southern Norway. Using an ensemble of Max Planck Institute ESM transient simulations for 521–680 CE, the temperature, precipitation and atmospheric circulation patterns are studied. The simulated cooling magnitude is then used as input for the growing degree day (GDD) model set-up for Southern Norway. This GDD model indicates the possible effects on agriculture for three different study areas in Southern Norway, representative of typical meteorological and landscape conditions. Pollen from bogs and archaeological records inside the study area are then analysed at high resolution (1–3 cm sample intervals) to give insights into the validity of the GDD model set-up with regard to the volcanic climate impact on the regional scale, and to link the different types of data sets. After the 536/540 CE double event, a maximum surface air cooling of up to 3.5 °C during the mean growing season is simulated regionally in Southern Norway. With a worst-case scenario cooling of 3 °C, the GDD model indicates crop failures were likely in our northernmost and western study areas, while crops were more likely to mature in the southeastern study area. These results are in agreement with the pollen records from the respective areas. During the sixth century, excavations show an abandonment of farms, severe social impact but also a continuation of occupation or a mix of those. In addition, archaeological findings from one of the excavation sites suggest wetter conditions for the mid-sixth century in Scandinavia, as simulated by individual ensemble members. Finally, we discuss the likely climate and societal impacts of the 536/540 CE volcanic double event by synthesising the new and available data sets for the whole Scandinavia.publishedVersio

Climate adaptation of pre-Viking societies

Understanding how the Viking societies were impacted by past climate variability and how they adapted to it has hardly been investigated. Here, we have carried out a new multi-proxy investigation of lake sediments, including geochemical and palynological analyses, to reconstruct past changes in temperature and agricultural practices of pre-Viking and Viking societies in Southeastern Norway during the period between 200 and 1300 CE. The periods 200–300 and 800–1300 CE were warmer than the 300–800 CE period, which is known as the “Dark Ages Cold Period”. This cold period was punctuated by century-scale more temperate intervals, which were dominated by the cultivation of cereals and hemp (before 280 CE, 420–480 CE, 580–700 CE, and after 800 CE). In between, cold intervals were dominated by livestock farming. Our results demonstrate that the pre-Viking societies changed their agricultural strategy in response to climate variability during the Late Antiquity.publishedVersio

Biodistribution of Poly(alkyl cyanoacrylate) Nanoparticles in Mice and Effect on Tumor Infiltration of Macrophages into a Patient-Derived Breast Cancer Xenograft

We have investigated the biodistribution and tumor macrophage infiltration after intravenous injection of the poly(alkyl cyanoacrylate) nanoparticles (NPs): PEBCA (poly(2-ethyl-butyl cyanoacrylate), PBCA (poly(n-butyl cyanoacrylate), and POCA (poly(octyl cyanoacrylate), in mice. These NPs are structurally similar, have similar PEGylation, and have previously been shown to give large variations in cellular responses in vitro. The PEBCA NPs had the highest uptake both in the patient-derived breast cancer xenograft MAS98.12 and in lymph nodes, and therefore, they are the most promising of these NPs for delivery of cancer drugs. High-resolution magic angle spinning magnetic resonance (HR MAS MR) spectroscopy did not reveal any differences in the metabolic profiles of tumors following injection of the NPs, but the PEBCA NPs resulted in higher tumor infiltration of the anti-tumorigenic M1 macrophages than obtained with the two other NPs. The PEBCA NPs also increased the ratio of M1/M2 (anti-tumorigenic/pro-tumorigenic) macrophages in the tumors, suggesting that these NPs might be used both as a vehicle for drug delivery and to modulate the immune response in favor of enhanced therapeutic effects

Royal villas in Northern Europe

This paper concerns land use and peasant society relating to settlements, power, and state formation in Northern Europe in the period 500–1200 AD, combining archaeological and written evidence in spatial landscape studies. In the mainly rural society in the Middle Ages, political and economic power seems to have been based on control over land, including people, land, and estates. The king and his followers travelled between a limited numbers of royal villas, located in the coastal areas or by central rivers and important route-ways. Due to urbanisation and supra-regional state formation, this system gradually changed. Around 900–1100 AD, new towns were established as the main urban centres, which gradually became the king’s residences and powerbase. During the High Middle Ages, the old rural manors and estates of the king were split into several units and donated to the king’s secular allies and ecclesiastical institutions such as bishops, monasteries, and churches, often located in the towns
