Germans from Russia in Saskatchewan: An Oral History

The Germans from Russia are a prominent settlement group in the rural landscape of Saskatchewan. Perhaps because they came incrementally, by chain migration, rather than by organized group colonization, they compose an ethnic group little noticed by historians. Also, their immediate origins are divided, inasmuch as earlier German-Russian immigrants came directly from Russia, whereas many twentieth-century German-Russian immigrants came to Canada from the United States, mainly from North Dakota and South Dakota. This article offers the first focused, scholarly historical treatment of German-Russian immigration and life in Saskatchewan. Drawing on oral histories collected with the support of the Faculty Research Program of the Canadian Embassy, it focuses particularly on growing up German-Russian on the prairies, positing a German-Russian ethnic identity distinct both from neighbor immigrant groups in Saskatchewan and from origin communities in the United States.     

The Neolithic Transition in the Iberian Peninsula: Data Analysis and Modeling

We apply GIS techniques to analyze a carefully selected database of 93 Early Neolithic sites in the Iberian Peninsula. This allows us to study the spatial dynamics of the Neolithic transition in Iberia. We study how the Neolithic was introduced into the peninsula in order to test the hypothesis that the Neolithic was introduced almost simultaneously from two sources: one at the northeast (via the Mediterranean coast) and another one at the south (possibly from Northern Africa). We also analyze how the expansion of the Neolithic transition took place within the Iberian Peninsula and measure local rates of spread in order to identify regions with fast and slow rates (such as the slowdown at the Cantabrian coast). In addition, we attempt to reproduce the main results obtained from the GIS analysis by applying reaction–dispersal models to the expansion of the Neolithic transition in the Iberian Peninsula. We conclude that a model with two sources is a reasonable assumption that agrees better with the archaeological data available at present than a model with a single source.     

Anthropogenic units fingerprinted by REE in archaeological stratigraphy: Mas d'Is (Spain) case

On occasions, archaeologists have to deal with serious difficulties to differentiate between processes that ultimately are responsible for the formation of stratigraphic units.Sometimes we face problems related with depositional units in multilayered deposits and other times, we ask for the character of some dark surface soils, very similar to natural paleosols and usually associated with archaeological findings. In both cases, the problems we must address concern the relative impact of human activities.The imbalance between anthropic and natural processes in the formation of archaeological deposits is crucial for a correct interpretation of the processes involved in the formation of archaeological sites, but also of their occupation-abandonment dynamics and the understanding of their spatial behaviors and relationship with the environment.In this paper we propose a new methodological approach for the identification of anthropogenic fingerprints in stratigraphic units through Rare Earth Elements (REE) soil analysis. The role of REE for the effective identification of sediment provenance due to their coherent behavior during weathering, erosion and fluvial transportation and their high resistance to chemical mobilization is well known in other areas of knowledge. We try to explore its potentiality in a challenging archaeological context. Our purpose was to identify human traces in stratigraphic units where archaeological materials are scarce or absent intertwined with others richer in archaeological remains by the determination of multiple elements and statistical studies. We believe that Rare Earth Elements (REE) soil analysis provides unique insights for a better characterization of natural and archaeological sediments but more importantly to recognize different stages of the gradient. We expect to discern between natural versus anthropic units and between primary versus secondary deposits (redeposition), using the case of the Neolithic site of Mas d'Is (Alicante, Spain) as an example. The application of the Principal Component Analysis (PCA) remarks differences in REE values, those analysis show differences between units of undoubtedly anthropogenic origin and control samples taken from natural sediments –including marls bedrock–, in their vicinity, but also we could notice finer nuances like the degree of human contributions to paleosols formation.     

Modelling the effect of Mesolithic populations on the slowdown of the Neolithic transition

The expansion of the Neolithic transition in Europe took place gradually from the Near East across the whole continent. At Northern Europe, observations show a slowdown in the speed of the Neolithic front in comparison to other regions of the continent. It has been suggested that the presence of high population densities of hunter-gatherers at the North could have been the main cause for this slowdown. This proposal has recently been described by a mathematical model that takes into account: (i) the resistance opposed by the Mesolithic populations to the advance of Neolithic populations in their territory, and (ii) a limitation on the population growth dynamics due to the competition for space and resources. But these two effects are not equally responsible for the slowdown of the spread. Indeed, here we show that the limitation on the population growth dynamics seems to have been the main cause of the delay of the expansion of farming in Northern Europe.
