Mollusk shells from burials of tuzovskiye bugry-1 As indicators of ethno-cultural processes In southern siberia and western central asia In the 3rd millennium bc

This article focuses on adornments made of mollusk shells from graves of the Tuzovskiye Bugry-1 burial ground in the Altai Territory. The collection includes bivalve shells: Corbicula ferghanensis Kurs. et Star. currently inhabiting the Amu Darya and Syr Darya basins; Corbicula tibetensis Prash. inhabiting the mountain regions of Central Asia, Eastern Kazakhstan, and the Amu Darya and Syr Darya basins; fossil Corbicula similar to Corbicula fl uminalis Mull; swan mussel of the genus Colletopterum inhabiting the Ob basin; and one specimen of Cardiidae sp. of the marine, probably, paleospecies. The most interesting are ancient marine tooth shells related to the genus Dentalium (class Scaphopoda, family Dentaliidae). In the Altai Territory, there are no such deposits that could have contained such shells. These shells were possibly brought by people from other regions. The closest occurrences of Dentaliidae are known in the Aral Sea region. The presence of beads of a truncated cone shape made of Dentalium shells as well as pendants made of Corbicula valves suggest connections between the Altai population and people inhabiting Western Central Asia. These connections might have existed in the form of direct contacts with bearers of the Ust-Narym and Botai cultures or else might have been the result of migration of people from Western Central Asia and Eastern Kazakhstan to the Altai.

REAL-TIME RISK ANALYSIS FOR HYBRID EARTHQUAKE EARLY WARNING SYSTEMS

Earthquake Early Warning Systems (EEWS), based on real-time prediction of ground motion or structural response measures, may play a role in reducing vulnerability and/or exposition of buildings and lifelines. In fact, recently seismologists developed efficient methods for rapid estimation of event features by means of limited information of the P-waves. Then, when an event is occurring, probabilistic distributions of magnitude and source-to-site distance are available and the prediction of the ground motion at the site, conditioned to the seismic network measures, may be performed in analogy with the Probabilistic Seismic Hazard Analysis (PSHA). Consequently the structural performance may be obtained by the Probabilistic Seismic Demand Analysis (PSDA), and used for real-time risk management purposes. However, such prediction is performed in very uncertain conditions which have to be taken into proper account to limit false and missed alarms. In the present study, real-time risk analysis for early warning purposes is discussed. The magnitude estimation is performed via the Bayesian approach, while the earthquake localization is based on the Voronoi cells. To test the procedure it was applied, by simulation, to the EEWS under development in the Campanian region (southern Italy). The results lead to the conclusion that the PSHA, conditioned to the EEWS, correctly predicts the hazard at the site and that the false/missed alarm probabilities may be controlled by set up of an appropriate decisional rule and alarm threshold.     

The Aral Sea Crisis and Its Future: An Assessment in 2006

An American geographer and noted international authority on water management problems in Russia and Central Asia presents an account of an expedition, in late 2005 (under the sponsorship of the National Geographic Society) to Kazakhstan and Uzbekistan, focused on the Aral Sea. The steadily drying inland sea, with a surface area of 67,500 km² in 1960, had split into two parts and shrunk to 17,380 km2 in 2006. The paper provides an up-to-date overview of the crisis and presents an optimistic scenario of the sea's future, noting development of economic activities (particularly fisheries) in its surrounding settlements.

Historical Perspectives on Pre-Colonial Irrigation in Southern Africa

Abstract

One of the basic areas of interaction between water as natural resource and human societies as agents of cultural transformation is the technology of irrigation. In Africa at least 66 per cent of the available water is used for purposes of irrigation. For more than 4 000 years irrigation has secured food supplies for humans on a continent that is noted for its relative shortage of sufficient natural water supplies.

There is a remarkable hidden power of water in the history of southern Africa. This is particularly the case when we consider the development of early irrigation technologies of Iron Age farmers. The small irrigation furrow of the subsistence farmer was just as important to an insular community of Bantu-speaking people in pre-colonial times, as is the sophisticated irrigation technology in present-day South Africa. Currently there is a paucity of information about pre-colonial indigenous irrigation technology. This can be ascribed to a number of factors of which the invasion of modern Western traditions in the nineteenth century is perhaps the most important. A number of other factors for the apparent blind-spot is also presented in this study.

In southern Africa there are traces of indigenous pre-colonial irrigation works at sites such as Nyanga in Zimbabwe; the Limpopo River Valley; Mpumalanga; and South Africa's eastern Highveld. Reference is also made in this article to specific strategies of irrigation used by Iron Age communities, prior to the advent of a colonial presence. Finally, attention is also drawn to pre-colonial land tenure and state formation against the backdrop of Wittfogel's theories on hydraulic society.     

Becoming Rafinesque: Market Society and Academic Reputation in the Early American Republic

This article focuses on how knowledge came to be valued in conflicting ways in the American Republic during the 1820s and 1830s – one based on a market model that considered knowledge to be a commodity for sale, and another that produced cultural value through social connections created in new academic institutions. Constantine Rafinesque, who taught at Transylvania University in Kentucky, and his research in the natural sciences serve as an example of the first sort of scholarship. His life also illustrates how a market society could lead to dandies, like Rafinesque himself, even in academia, and how that threatened both new middle class social proprieties and a system of clubby social relations that had come to dominate America’s colleges and universities in the early nineteenth century.     

The nature of third-millennium settlement: The example of al-Tikha (Rustaq) an Umm an-Nar site on the Batinah coast of Oman

al-Tikha is a mid to large Umm an-Nar (c. 2700–2000 BC) settlement situated near Rustaq at the back of the Southern Batinah coastal plain in the Sultanate of Oman that was discovered (or rediscovered) in 2014. The site is unique because its layout and spatial organisation are very largely (possibly completely) visible on the surface. This includes two separate areas of stone-built housing, a large pottery scatter of varying density, three or four typical Umm an-Nar round towers and a small cemetery consisting of at least four tombs, along with a few other features. The layout of the site is described and discussed in detail, in particular, in relation to what it might tell us about the nature of Umm an-Nar settlement and social organisation more generally. The location of the site within a pattern of repeating Umm an-Nar settlement along Wadi Far (Wādī al-Farʿī) is also described and discussed.     

Comments on archaeology into the 1990s

This article focuses on the complexity of Early Bronze Age weapon depositions. While some of the deposited weapons have been disabled by intentional breakage, others seem to be more or less unused. A plausible explanation for the variability is that the surrender of lethal weapons to land or water was a means of coping with their power or agency – their individuality. We suggest that weapons, in their capacity as extensions of warriors’ bodies, may have substituted for humans in ritual depositions. The metalworkers also come into play, due to their capacities in the processes of making weapons and shaping weapon technologies. Although we consider the three depositions that we discuss to relate to rituals on the occasion of warfare, we are not aiming for a uniform explanation. In the same way as the patterned human behaviour of a ritual is a means of subsuming individual events into a greater order, so a focus on general patterns may subsume the complexity of the past by ignoring the many different events leading to, e.g., the deposition of metalwork. Far from seeing these perspectives as contradictory, we try to use three well-documented individual cases to shed light on the variability within the pattern.     

Beyond Alternative: Exploring the Potential for Autonomous Food Spaces

Abstract: Much attention has been given in recent years to the rise of alternative food networks However, the very concept of “alternative” has come under increasing scrutiny, as theorists grapple with what is meant by alternative and whether the concept adequately captures the key components of such a diverse range of networks and communities. Drawing on poststructuralist political economy, I propose the concept of autonomous food spaces as one possible lens for approaches food‐provisioning activities that situate food within the broader context of non‐capitalist communities seeking to build relationships of mutual aid and non‐market exchanges. I use the examples of a radical collective kitchen, Food Not Bombs, and a community‐supported agriculture operation, Vegetables Unplugged, to explore the potential for autonomous food spaces as part of a broader “politics of possibilities” beyond capitalism.     

Labour Control in the Tobacco Agro‐spaces: Migrant Agricultural Workers in South‐Western Ontario

International labour migration programs provide a vulnerable workforce that services various sectors in developed economies. The agriculture sector is one arena in which the employment of migrant workers has become more pervasive. Annually, approximately 30,000 workers are employed in the Canadian agriculture sector through the Seasonal Agricultural Workers Program (SAWP). In this paper, I focus on the SAWP workers in tobacco farming, and investigate the ways that labour control is achieved on two small‐scale farms. I draw upon original empirical evidence from interviews with three Mexican and nine Jamaican workers, two union representatives, and two farm owners in South‐Western Ontario, Canada. My findings show that various factors at multiple scales shape the labour control regime and significantly advantage farm owners over workers. Based on my findings, I argue that the labour control regime is conditioned exogenously by multi‐scalar factors and generated endogenously at the point of production.
