Space-time geography of female live-in child domestic workers in Dhaka,Bangladesh

Live-in child domestic workers in Bangladesh often experience the surveilling power of their employer's gaze as a Foucauldian panopticon, which both disciplines and engages children in forms of self-discipline. I argue that female child domestic workers in particular have a form of ‘thin’ agency whereby they are severely restricted in their abilities to make independent decisions or to act to their own benefit. I ethnographically unpack the concept of thin agency by analyzing material, cultural, spatial and discursive constraints that both employers and female child domestic workers engage in their daily lives.     

Degradation of Archaeological Wood Under Freezing and Thawing Conditions—Effects of Permafrost and Climate Change

The degradation of archaeological wood at freezing and thawing temperatures is studied at the site of Qajaa in West Greenland through a combination of environmental monitoring, measurement of oxygen consumption and microscopy of wood samples. Permanently frozen wood is still very well preserved after 2–4000 years, while wood samples that thaw every summer show attack by soft rot and an average density loss of 0.1 g cm^–3 (corresponding to 25% of the dry mass) over the past 27 years. Future increases in temperature may increase the decay rate significantly (Q₁₀ = 4.2 at 0–10°C) but the effects on site depend on local hydrology.     

Mode‐Locking and Regional Business Cycle Synchronization*

Abstract. Business cycles in different regions of the United States tend to synchronize. This study investigates the reasons behind this synchronization of business cycles and the consequent formation of a national business cycle. Trade between regions may not be strong enough for one region to “drive” business cycle fluctuations in another region. This study suggests that regional business cycles synchronize due to a nonlinear “mode‐locking” process in which weakly coupled oscillating systems (regions) tend to synchronize. There is no definitive test for mode‐lock. However, simulations, correlations, Granger causality tests, tests for nonlinearities, vector autoregressions, and spectral analysis reveal modest econometric support for the regional mode‐locking hypothesis of business cycle synchronization.     

Arsenic in Danish and Swedish Mesolithic and Neolithic human bones – diet or diagenesis?

Arsenic has previously been measured in a bone sample of a c. 5-year-old Mesolithic child from Nivaagaard in Denmark yielding an anomalously high value of 13 μg/g. In the present work we show that other individuals at a nearby site also exhibit elevated arsenic levels, whereas individuals from other Mesolithic sites in Denmark are found to have quite low As-concentrations. Several attempts to reveal the source of the arsenic are reported: A railway track near the site, where the railway sleepers were suspected to have been impregnated with As leading to transport or diffusion of As into the adjacent soil; Several food items, the remains of which were found at the site, and one food item not preserved in the excavation, i.e. seaweed. Finally, it is shown that the most likely explanation of the elevated arsenic levels in human bones at Nivaa is diagenesis.     

THE MEDIEVAL URBAN CHURCHYARD AS A MEETING PLACE: A CASE STUDY OF FUNCTION AND ORGANISATION OF THE CHURCHYARD OF ST. CLEMENS IN COPENHAGEN

The article presents the results of a study based on activity analysis of a medieval churchyard of St. Clemens in the urban setting of Copenhagen. The churchyard was in function from the 11^th to 16^th century revealing changes in layout and burial rites over time. A glimpse of the symbolic life of the medieval Copenhageners is also exposed and analysed. Moreover, the study of the churchyard reveals activities of a more secular nature and presents some of the activities that must have been part of everyday life in the medieval town. Thus, the churchyard has not only been an arena for meetings between the living and the dead but also a location for experiencing the urban life burgeoning outside the churchyard. For comparison, a recently discovered contemporaneous churchyard at Rådhuspladsen is also discussed.     

Seasonal Patterns of Coastal Exploitation on the Farasan Islands,Saudi Arabia

Here we present the results of the analysis of coastal exploitation patterns in the southern Red Sea during the Middle Holocene. We focus on the shell midden cluster of the Farasan Islands, Saudi Arabia, which comprises over 3,000 shell midden sites. These sites date from 6,500 to 4,500 cal BP and are part of an arid landscape. We focus on one site, JW1727, which provides a snapshot of marine exploitation and will help to understand the use of food resources within the region. Stable isotope values (δ¹⁸O) were collected from the marine gastropod Conomurex fasciatus (Born 1778), which represents 72% of shell weight of JW1727, in order to reconstruct the season of capture. Results demonstrate that 1) every season is represented within the dataset; and 2) there is increased C. fasciatus deposition during the summer and autumn months. This indicates a diet consisting of C. fasciatus throughout the year in combination with other food sources and an increase of the C. fasciatus component during the arid seasons, possibly linked to the unavailability of vegetation. Additionally, size measurements of C. fasciatus were carried out to examine changes in size distribution throughout the occupation of the site that could be related to overexploitation of C. fasciatus. However, no significant trends could be observed. In sum, the results suggest a sustainable and constant habitation of the Farasan Islands despite the highly arid conditions.     

Exploring Accumulation Rates of Shell Deposits Through Seasonality Data

Shell middens are often analysed as the result of short- or long-term depositional activities. In order to confidently interpret such deposits, it is necessary to have accurate estimations of shell accumulation rates, most commonly produced by radiocarbon dates. This paper introduces the application of seasonality data as a temporal measurement of short-term shell deposition. This gives access to an additional estimate of shell accumulation rates, which work on a shorter timescale than can be analysed through radiocarbon dating. We focus on shell deposits on the Farasan Islands, Saudi Arabia, which comprise over 3000 shell midden sites dating to the mid-Holocene (6500–4500 calBP). One site (JW1727) was chosen to (1) explore the potential of seasonality data to reconstruct accumulation rates, (2) analyse the intensity of exploitation and (3) assess the visibility of short-term shellfish deposits. Stable oxygen isotope values (δ¹⁸O) were obtained from the marine gastropod Conomurex fasciatus (Born 1778), representing 72 % of the shell weight of JW1727, to reconstruct season of capture. Seasonality data was grouped by their spatial distribution, which allowed successive episodes of deposition within a stratigraphic sequence to be connected. This allowed us to make an estimation of exploited shell meat of ～200 kg over a 7-month period (～400 shells/day). We argue that excavation methods and low resolution stratigraphic data cause imprecision in the seasonality data and the low visibility of rapidly accumulated shell deposits. Also, an increase of analysed shells per layer is key to understanding the seasonal brickwork of more middens in the future.     

Mars (1564): the initial archaeological investigations of a great 16th‐century Swedish warship

Before the Swedish warship Mars exploded and sank in action against a combined Danish and Lübeckian fleet in 1564, it was one of the largest ships in the world. In 2011 the wreck was relocated off the island of Öland in the Baltic Sea. Thanks to the favourable conditions in the brackish water, about two thirds of the hull is preserved on the sea bottom, including the stern with the large sterncastle. The aim of this article is to present initial archaeological observations and results of work since 2011. We briefly describe the historical context and research perspectives regarding this wreck.
