Isenya: état des recherches sur un nouveau site acheuléen d'Afrique orientale

Résumé Isenya est le premier site acheuléen fouillé sur les hauts plateaux du Kenya. Sa richesse en vestiges lithiques et fauniques en fait dès maintenant un gisement important pour la connaissance des hominidés du Pléistocène moyen. Isenya est inclus dans un contexte sédimentaire fluviatile, indiquant que les hommes préhistoriques se sont installés sur une barre sableuse, le long d'une rivière qui était alors peut-être pérenne. La convergence des informations géologiques et archéologiques permet d'expliquer la mise en place des vestiges, la positionin situ de plusieurs niveaux d'occupation superposés, le faible degré de perturbation qu'ils ont subi, et l'origine essentiellement anthropique des associations os/pierres. L'industrie lithique est caractérisée par une grande abondance de bifaces et de hachereaux dont les proportions varient dans le temps. Une première analyse de l'ensemble apporte d'ores et déjà des indications sur les comportements techniques: les chaînes opératoires sont décryptées, depuis l'acquisition des matériaux jusqu'à l'obtention des outils. La faune associée à cet outillage est dominée par des animaux de savane ouverte (Alcelaphini etAntilopini). Son étude détaillée mettra en évidence les stratégies d'acquisition du gibier et son mode de consommation. Attirés, entre autres raisons, par la proximité de l'eau et des affleurements de phonolite, source principale de matière première pour l'outillage, les hominidés ont occupé cet enfroit de façon répétée dans un court laps de temps, selon une périodicité à rapprocher sans doute des comportements de subsistance.

Isenya is the first Acheulian site excavated in the Eastern Highlands of Kenya. Very rich lithic and faunal remains in a fluviatile sedimentary context indicate hominid activity on a sandy bar next to a river, which was perhaps perennial. Microstratigraphy and archaeological data permit reconstruction of the processes by which the remains were deposited. Severalin situ occupation layers show only a slight degree of perturbation. The bone assemblage is of anthropic origin, and the lithic industry is characterized by an abundance of bifacial pieces, level VI being particularly rich in cleavers. From the analysis of the lithic industry we can obtain some idea of hominid technological behaviour, most notably the operational chains of tool production from the procurement of raw materials to the knapping sequences. The fauna associated with the lithic materials is dominated by animals of the open savanna (Alcelaphini andAntilopini); and its detailed study will allow us to specify the strategies used in the procurement of game and its subsequent consumption. Without doubt, the reasons for hominid occupation at this particular site will be impossible to explain fully. However, choice of this location, where evidence for several different activities has been uncovered, should be considered in terms of the proximity both of water and of outcrops of phonolite, the principal raw material for tool-making. Repeated occupation by hominids over a short time may, perhaps, correspond to the periodicity of their subsistence behaviour.

     

A forgotten plague

Dysentery, or rödsot, as the disease was previously known in Sweden, continues to be a major scourge in developing countries. However, the disease has almost disappeared in the West. Very different circumstances prevailed before infectious diseases declined as some of the major causes of death during the 19th century. In that era, 10,000 people could die of dysentery in a single year in Sweden. The demographic consequences of dysentery in Sweden and the causes of the disease and its disappearance are discussed in this article. It is shown here that despite the devastating effects of dysentery epidemics, most government actions were targeted at cholera. Considerable regional and local differences are revealed as the disease is mapped over Sweden. Clusters of high mortality formed, and even in hard-hit Jönköping County some parishes were almost never affected. It becomes apparent that the outbreaks have been the result of complex interactions between different variables and have led to widespread disease of uneven and often epidemic proportions.

For the statistical analyses the digitized source material of the Demographic Data Base (DDB) at Umeå University has been used, containing statistical demographic data gathered from parishes from all over Sweden. Other sources drawn upon include published statistical data, reports from district medical officers, newspapers, parish registers, and maps.     

Exploring children's foodscapes

In this article, we discuss children's becoming as food consumers in the intersection of various foodscapes. We draw from a project, Children as co-researchers of foodscapes, where we have been working with children as co-researchers, using basically ethnographic methods, and as co-designers in a collaborative design effort. This article focuses on the findings from a theoretically inspired perspective, using the concept of foodscapes. These are food-related structures of different kinds, which evolve as the child explores them and where children as food consumers are generated. In this article, we highlight the scapes of taste, routines, people, things, commerce, child (as opposed to adult) and health and give brief accounts of the way the children related to them. Finally, we turn to the benefits of working with foodscapes for a better understanding of children's becoming as food consumers in the intersection of various foodscapes. This article is based on data gathered by the children, but also on our fieldwork notes and observations following the children in their foodscapes.     

Contested Sources of Authority: Re‐claiming State Sovereignty by Formalizing Traditional Authority in Mozambique

In Mozambique, the current legal framework institutionalizes a rural–urban differentiation of local governance, allowing for elected representation in thirty‐three urban settings and the recognition of ‘community authorities’ in rural areas. This article deals with the latter by exploring the implementation of Decree 15/2000, which is the first legislation in post‐colonial Mozambique to formalize ‘traditional authority’. Views of traditional authority as either a ‘genuine’ African form of authority legitimized by traditional beliefs and practices, or as a form of power ‘corrupted’ by colonial rule, are inadequate for understanding the current situation. In formerly war‐torn Sussundenga District, kin‐based authorities drew on elements from ‘traditional’ and ‘state‐administrative’ domains of authority in order to be recognized. Varied definitions of tradition came to justify leadership, but the content on which legitimization was based defies any generalized Weberian dichotomy between traditional and modern/state types of office. Different sources of legitimacy sometimes foregrounded administrative needs and at other times maintained what became defined as traditional.     

Late Holocene Changes in Shellfishing Behaviors From the Gulf of Carpentaria,Northern Australia

ABSTRACT

Dramatic changes in shellfishing behaviors occur across northern Australia during the late Holocene, marked most conspicuously by the cessation of large shell mound construction in some areas, and the reorganization of shellfishing behaviors towards more intensive production in the last 1,000 years. Excavations reveal rapid and widespread changes within coastal sites, an increasing diversification in overall subsistence resources, and patterns of increase in site establishment and use. Some of these changes have been argued to be associated with increasing climate variability and a trend towards increasing aridity during the late Holocene, thought to have transformed coastal ecosystems and mollusc availability. However, when these hypotheses are tested at the local level, more nuanced patterns of human-environment interaction emerge, which call into question interpretations based on broad-scale climate records. We suggest that disjunctions in the timing of the cessation of shell mound construction noted between the west and east Gulf of Carpentaria may be related, at least in part, to the timing and intensity of external cultural contacts with Macassan seafarers, associated with reorganization of mobility and production strategies, rather than as yet undemonstrated environmental changes impacting on shellfish availability.     

The Purpose of Porphyry's Letter to Marcella

Porphyry's Letter to Marcella was ostensibly written by the Neoplatonic philosopher, while away on a mission on behalf of the Greeks, in order to encourage his wife, Marcella, to continue her study of philosophy during his absence. The precise date of the letter is uncertain. It is here argued that it was intended for public circulation and should be seen in association with Porphyry's anti-Christian polemic. It can be interpreted as a protreptic text intended to convert its readers to true philosophy, and it is suggested that it was directed to those women who might otherwise be attracted to Christianity. Marcella can be said to represent the intended readership of the letter.     

High-resolution radiocarbon dating of marine materials in archaeological contexts: radiocarbon marine reservoir variability between Anadara, Gafrarium, Batissa, Polymesoda spp. and Echinoidea at Caution Bay, Southern Coastal Papua New Guinea

The remains of shellfish dominate many coastal archaeological sites in the Pacific and provide a wealth of information about economy, culture, environment and climate. Shells are therefore the logical sample type to develop local and regional radiocarbon chronologies. The calibration of radiocarbon (¹⁴C) dates on marine animals is not straightforward, however, requiring an understanding of habitat and dietary preferences as well as detailed knowledge of local ocean conditions. The most complex situations occur where terrestrial influences impinge on the marine environment resulting in both the enrichment and depletion of ¹⁴C (Ulm Geoarchaeology 17(4):319–348, 2002; Petchey and Clark Quat Geochronol 6:539–549, 2011). A sampling protocol that combines a high-resolution excavation methodology, selection of short-lived samples identified to species level, and a tri-isotope approach using ¹⁴C, δ¹³C and δ¹⁸O, has given us the ability to identify ¹⁴C source variation that would otherwise have been obscured. Here, we present new research that details high-resolution mapping of marine ¹⁴C reservoir variation between Gafrarium tumidum, Gafrarium pectinatum, Anadara granosa, Anadara antiquata, Batissa violacea, Polymesoda erosa and Echinoidea from the Bogi 1 archaeological site, Caution Bay, southern coastal Papua New Guinea. These isotopes highlight specific dietary, habitat and behavioural variations that are key to obtaining chronological information from shell radiocarbon determinations.     

On the identity of NATO

Although we may well be missing the point about NATO if we conceptualize it as just another military alliance, defining NATO as a community of liberal democratic values and norms is problematic. A distinction must be made between a community of values linked to particular experiences and a particular context and a community based on democratic principles. What has kept NATO together beyond the Cold War is a sense of shared history and fate. If such a 'value-hypothesis' about NATO is correct, the continued survival of the organization does not depend only on the marginal costs of maintaining it continuing to outweigh those of creating a new organization. The future of NATO will also depend on the extent to which it is possible to restore (or reestablish) a sense of shared fate and mutual confidence across the Atlantic.
