Eclectic and pragmatic: the colours of Dutch social and cultural geography

In the Netherlands, human geography has traditionally been an applied, practical science. Close ties have always existed with spatial planning and regional-economic policy. With good reason, the first generation of planning specialists—in the 1960s—consisted largely of people trained as geographers. Geographers were also the socio-spatial engineers of the welfare state (de Pater 2001b; de Pater and de Smidt 1989).     

Prehistoric migration at Nebira, South Coast of Papua New Guinea: New insights into interaction using isotope and trace element concentration analyses

Migration is a commonly used explanation for cultural change in world prehistory, and is also a central theme in the prehistory of the Pacific Islands. However it is rarely subject to direct archaeological research. This paper applies strontium and oxygen radiogenic/stable isotope (⁸⁷Sr/⁸⁶Sr, δ¹⁸O), and trace element concentration (Ba/Sr) analyses to 27 individuals buried at the archaeological site of Nebira (ca.720–300 BP), located inland on the South Coast of Papua New Guinea. The analyses seek to identify non-local individuals within the population and provide a more in-depth understanding about the social identity of the possible migrants in this community.The strontium isotope data indicates that five individuals were non-local to Nebira, having possibly come from a coastal location. Correlation with biological data, such as age and sex, also indicates that the pattern of migration at Nebira was not sex or age specific. The results support the archaeological findings that suggest the inhabitants from Nebira were in contact with coastal communities during a period in prehistory of increased cultural interaction. However, despite the considerable isotopic variation identified in the Nebira sample, it is also demonstrated that more research is needed to identify the possible origins of these non-local individuals.     

Computational Reproducibility in Archaeological Research: Basic Principles and a Case Study of Their Implementation

The use of computers and complex software is pervasive in archaeology, yet their role in the analytical pipeline is rarely exposed for other researchers to inspect or reuse. This limits the progress of archaeology because researchers cannot easily reproduce each other’s work to verify or extend it. Four general principles of reproducible research that have emerged in other fields are presented. An archaeological case study is described that shows how each principle can be implemented using freely available software. The costs and benefits of implementing reproducible research are assessed. The primary benefit, of sharing data in particular, is increased impact via an increased number of citations. The primary cost is the additional time required to enhance reproducibility, although the exact amount is difficult to quantify.     

Government and (non)event: the promise of control

Control rooms routinely deal with happenings that might become events. They attempt to hide events and their possibility from the users of infrastructure by undertaking various forms of action to stop events coming to pass. Based on ethnographic research in a motorway control room, in this paper we describe how events are grasped and handled and subject to the effect of control. Focusing on how the promise of control is provisionally achieved through detection–diagnosis–response work, we show how control room action is situated on the ambiguous line between event and non- or quasi-event and involves making happenings that might be or might become events into their opposite: non-events, or routine occurrences. We use the case of the work of control rooms in dialogue with Michel Foucault on the relation between ‘government and event’ and Lauren Berlant on ‘modes of eventfulness’ to challenge the emphasis on the event as dramatic transformation in some current research on securing life and some geographical work on events. Paying close attention to what control rooms do shows the multiplicity of relations between government and (non)event, and invites us to expand the ‘modes of eventfulness’ that social and cultural geographers learn to sense and disclose.     

Application of lipid biomarker analysis to evaluate the function of ‘slab-lined pits’ in Arctic Norway

Gas chromatography–mass spectrometry (GC–MS) and bulk carbon isotope determinations have been performed on samples (‘cemented organic residues’, charcoal, sediment and fire-cracked rock) excavated from 12 slab-lined pits from various locations in Arctic Norway to test the premise that these archaeological features were used for the extraction of oil from the blubber of marine mammals, such as seal, whale and walrus. A wide range of lipid compound classes were detected especially in the cemented organic residues and in the charcoal samples. The presence of long-chain unsaturated and isoprenoid fatty acids together with oxidation and thermal alteration products of unsaturated acids such as dicarboxylic acids, dihydroxyfatty acids and ω-(o-alkylphenyl)alkanoic acids suggests that these features were used for marine oil extraction at elevated temperatures. Notably the location of the hydroxyl groups in the dihydroxyfatty acids provides a record of the positional isomer of the precursor fatty acid and allows confirmation that 11-docosenoic (cetoleic) acid, the most abundant C_22:1 isomer in marine oil, was a major component of the original lipid. Further information was provided by the presence of long-chain fatty acyl moieties in surviving triacylglycerols and the presence of cholesterol. A fungal metabolite, mycose (trehalose), was found in all samples apart from a fire-cracked rock and points to microbiological activity in the pits. Bulk isotope analysis conducted on the ‘cemented organic residues’ is consistent with modern reference samples of blubber and oil from seal and whale. These data provide clear analytical evidence of the function of slab-lined pits in the archaeological record and suggest widespread exploitation of marine mammals for producing oil for heating, lighting and myriad other uses in the past.
