The Camera “at the Trowel’s Edge”: Personal Video Recording in Archaeological Research

Video recording is increasingly becoming a favourable medium in archaeological research, particularly as an unconventional documentation tool that captures the elusive processes of ongoing interpretation in an audiovisual format. Our research forms part of the Personal Architectonics Through INteraction with Artefacts (PATINA) project, a project focused on the design of technologies for supporting research. Archaeological fieldwork is one of the research environments being studied by the project, and one of our primary concerns was to observe and record current research practices in the wild and to examine the influence of new technologies on those practices. This research brings together well-established and advanced observation techniques used in social sciences and computing fields such as human–computer interaction with archaeological research and presents the deployment of an off-the-shelf wearable camcorder as a recording interface in archaeological fieldwork. The article discusses the user evaluation methodology and the results, while addressing long-standing and timely theoretical discussions on the role of video recording in archaeological research.     

Spatial Distribution of City Tweets and Their Densities

Social media outlets such as Twitter constitute valuable data sources for understanding human activities in the virtual world from a geographic perspective. This article examines spatial distribution of tweets and densities within cities. The cities refer to natural cities that are automatically aggregated from a country's small street blocks, so called city blocks. We adopted street blocks (rather than census tracts) as the basic geographic units and topological center (rather than geometric center) to assess how tweets and densities vary from the center to the peripheral border. We found that, within a city from the center to the periphery, the tweets first increase and then decrease, while the densities decrease in general. These increases and decreases fluctuate dramatically, and differ significantly from those if census tracts are used as the basic geographic units. We also found that the decrease of densities from the center to the periphery is less significant, and even disappears, if an arbitrarily defined city border is adopted. These findings prove that natural cities and their topological centers are better than their counterparts (conventionally defined cities and city centers) for geographic research. Based on this study, we believe that tweet densities can be a good surrogate of population densities. If this belief is proved to be true, social media data could help solve the dispute surrounding exponential or power function of urban population density.     

ORGANIZATION,LEGITIMATION, PARTICIPATION

This article suggests a new interpretation of the state formation process in Early Modern Sweden, focusing on three dimensions: The organization of the state as a way to use limited resources in a rational way, the legitimation of rulers in terms of beliefs and values current in society, and the participation of the subjects in state activities. Our model focuses on institutional change as a result of the intensity of interaction between rulers and subjects. Based on our own research, claims are made for new understanding of state formation in Europe that allows more room for political action from below.     

LABOUR AND LANDSCAPES: THE POLITICAL ECONOMY OF LANDESQUE CAPITAL IN NINETEENTH CENTURY TANGANYIKA

In a long‐term and global perspective irrigated and terraced landscapes, landesque capital, have often been assumed to be closely associated with hierarchical political systems. However, research is accumulating that shows how kinship‐based societies (including small chiefdoms) have also been responsible for constructing landesque capital without population pressure. We examine the political economy of landesque capital through the intersections of decentralized politics and regional economies. A crucial question guiding our research is why some kinship‐based societies chose to invest their labour in landesque capital while others did not. Our analysis is based on a detailed examination of four relatively densely populated communities in late pre‐colonial and early colonial Tanzania. By analysing labour processes as contingent and separate from political types of generalized economic systems over time we can identify the causal factors that direct labour and thus landscape formation as a process. The general conclusion of our investigation is that landesque investments occurred in cases where agriculture was the main source of long‐term wealth flow irrespective of whether or not hierarchical political systems were present. However, while this factor may be a necessary condition it is not a sufficient cause. In the cases we examined, the configurations of world‐systems connections and local social and economic circumstances combined to either produce investments in landesque capital or to pursue short‐term strategies of extraction.     

Mobilizing ‘juvenocratic spaces’ by the biopoliticization of children through sustainability

Northern children have been increasingly referred to as competent, participative and influential, called on to protect and produce certain life at times of climate risks. Child–adult relations and the required transition to adulthood are thus transformed by a re-configured ‘biopolitics’. We trace how various collaborative actors invite children to foster life at an aggregate level and illustrate how different age categories are governed at a distance. The results show that pedagogic expertise, in conjunction with sustainability, is mobilized in and by ‘juvenocratic spaces’, where youths are obliged to foster sustainable consumption and ways of living beyond territorial borders.     

Comment on Egil Bakka: Methodological problems in the study of Gold Bracteates,Norw. Arch. Rev. 1, 5–35

At some of the lakes on the mountain plateau Hardangervidda are found the remnants of large stone huts surrounded by middens rich in reindeer bones. On the opposite side of the lakes from these huts a number of cairns making up drift fences indicate that the animals were forced into the water, there to be killed by the hunters.

It appears that the method ‐ which was in use until the Black Death ‐ on the western side of Hardangervidda was known from before the Christian era, whilst on the eastern side it was first introduced in the Early Medieval Period.

The author discusses this variation and relates it to population movements and social change.
