Social networks, mobility, and exchange systems during the Neolithic and Bronze Age of the Swiss Plateau

Excavations of Neolithic (4000 ��� 3500 BC) and Late Bronze Age (1200 ��� 800 BC) wetland sites on the northern Alpine periphery have produced astonishing and detailed information about the life and human environment of prehistoric societies. It is even possible to reconstruct settlement histories and settlement dynamics, which suggest a high degree of mobility during the Neolithic. Archaeological finds���such as pottery���show local typological developments in addition to foreign influences. Furthermore, exogenous lithic forms indicate far reaching interaction. Many hundreds of bronze artefacts are recorded from the Late Bronze Age settlements, demonstrating that some wetland sites were centres of bronzework production. Exogenous forms of bronzework are relatively rare in the wetland settlements during the Late Bronze Age. However, the products produced in the lake-settlements can be found widely across central Europe, indicating their continued involvement in interregional exchange partnerships. Potential motivations and dynamics of the relationships between sites and other regions of Europe will be detailed using case studies focussing on the settlements Seedorf Lobsigensee (BE), Concise (VD), and Sutz-Lattrigen Hauptstation innen (BE), and an initial assessment of intra-site connectivity through Network Analysis of sites within the region of Lake Neuch��tel, Lake Biel, and Lake Murten.

Western Hindus and 'Global Hinduism' - Discourses on Conversion to 'Hindu-Religions', Acceptance of Converts and Social Engagement

The paper deals with the problem of (the often supposedly impossible) conversion to ���Hinduism���. I start with an outline of what I call the ���no conversion possible��� paradigm, and briefl y point to the lack of refl ection on acceptance of converts in most theories of religious conversion. Then, two examples are presented: Firstly, I consider conversion to ISKCON and the discourse on the Hare Krishna movement���s Hinduness. Secondly, I give a brief outline of the globalsanatana dharmamovement as inaugurated by Satguru Siva Subramuniyaswami, a converted American Hindu based in Hawai���i. In the conclusion, I refl ect on (civic) social capital and engagement in global networks as a means to gain acceptance as converts to Hinduism. I argue in line with Stepick, Rey and Mahler (2009) that the religious movements��� civic engagement (in these cases engagement in favour of the Indian diasporic communities and of Hindus in India) provides a means for the individual, non-Indian converts to acquire the social capital that is necessary for gaining acceptance as ���Hindus��� in certain contexts.

Spatial and temporal patterns of greenness on the Yamal Peninsula, Russia: interactions of ecological and social factors affecting the Arctic normalized difference vegetation index

The causes of a greening trend detected in the Arctic using the normalized difference vegetation index (NDVI) are still poorly understood. Changes in NDVI are a result of multiple ecological and social factors that affect tundra net primary productivity. Here we use a 25 year time series of AVHRR-derived NDVI data (AVHRR: advanced very high resolution radiometer), climate analysis, a global geographic information database and ground-based studies to examine the spatial and temporal patterns of vegetation greenness on the Yamal Peninsula, Russia. We assess the effects of climate change, gas-field development, reindeer grazing and permafrost degradation. In contrast to the case for Arctic North America, there has not been a significant trend in summer temperature or NDVI, and much of the pattern of NDVI in this region is due to disturbances. There has been a 37% change in early-summer coastal sea-ice concentration, a 4% increase in summer land temperatures and a 7% change in the average time-integrated NDVI over the length of the satellite observations. Gas-field infrastructure is not currently extensive enough to affect regional NDVI patterns. The effect of reindeer is difficult to quantitatively assess because of the lack of control areas where reindeer are excluded. Many of the greenest landscapes on the Yamal are associated with landslides and drainage networks that have resulted from ongoing rapid permafrost degradation. A warming climate and enhanced winter snow are likely to exacerbate positive feedbacks between climate and permafrost thawing. We present a diagram that summarizes the social and ecological factors that influence Arctic NDVI. The NDVI should be viewed as a powerful monitoring tool that integrates the cumulative effect of a multitude of factors affecting Arctic land-cover change.
