Detecting the environmental impact of the Baltic Crusades on a late-medieval (13th–15th century) frontier landscape: palynological analysis from Malbork Castle and hinterland,Northern Poland

Palaeoecological analysis of peat deposits from a small bog, combined with pollen analysis of sediments infilling the moat of the nearby Teutonic Order castle at Malbork, have been used to examine the ecological impact of the Crusades on the late-medieval landscape of Northern Poland. Studies of the environmental impact of the Crusades have been almost exclusively informed by written sources; this study is the first of its type to directly investigate the environmental context of Crusading as a force of ecological transformation on the late-medieval Baltic landscape. The pollen evidence from Malbork Castle and its hinterland demonstrate that the 12th/13th–15th centuries coincide with a marked transformation in vegetation and land-use, characterized by clearance of broadleaved woodland and subsequent agricultural intensification, particularly during the 14th/15th centuries. These changes are ascribed to landscape transformations associated with the Teutonic Order’s control of the landscape from the mid-13th century. Human activity identified in the pollen record prior to this is argued to reflect the activities of Pomeranian settlers in the area. This paper also discusses the broader palaeoecological evidence for medieval landscape change across Northern Poland.     

Obsidian types from Holocene sites around Lake Turkana,and other localities in northern Kenya

Obsidian has been widely used by early Holocene hunter-gatherers and succeeding Pastoral Neolithic peoples in northern Kenya. Here we report the results of over 2000 electron microprobe analyses of artifactual and non-artifactual obsidian from the greater Lake Turkana region. Of the 15 compositional types of obsidian observed, a preponderant type is widespread across the region from the Barrier in the south to Ileret in the north and east as far as Kargi. This obsidian is the principal type at Lowasera and most Pastoral Neolithic sites, including the Jarigole Pillar site and Dongodien (GaJi4). The source of this obsidian is not known, but based on its distribution the source may be located on the Barrier or in the Suguta Valley immediately to the south of Lake Turkana. Although there are several possible sources of local obsidian identified for minor types, in stark contrast to the central part of the Kenyan Rift, major sources of obsidian available for artifact manufacture are not known in the Lake Turkana region. The lack of obsidian from demonstrable Ethiopian Rift and central Kenyan Rift sources, and the absence of obsidian with compositions found at the Turkana area sites in assemblages in the central part of the Kenyan Rift suggests that the earlier Pastoral Neolithic peoples around Lake Turkana interacted with each other, but perhaps not as strongly with people farther south along the Rift Valley, even as herding practices were expanding to the southward into central Kenya.     

Scales and Skills of Monopoly Power: Labor Geographies of the 1890–1891 Chicago Carpenters’ Strike

Abstract: This paper builds upon labor geography's contributions to our understanding of the role of workers in the production of scale. In addition to examining exactly how a particular group of workers controlled the scale of their labor market, this paper theorizes the connections between that process and struggles over monopoly power. The 1890–1891 Chicago carpenters’ strike, a work stoppage of significance to both the direction of labor politics within Chicago and to the broader 8 h movement in North America at the end of the nineteenth century, serves as a case study.     

Ground truthing of remotely identified fortifications on the Central Coast of Perú

Remote imagery, including freely available satellite images viewed in Google Earth^® and historic aerial photographs, was used to identify anomalies in a 25,000 km² macroregion encompassing 13 river valleys along the Peruvian coast. These anomalies, located atop hills and mountains, were hypothesized prehispanic fortifications. A sample of remotely identified anomalies was ground truthed in the Huaura and Fortaleza Valleys on the Central Coast of Perú. 140 positive anomalies were documented and assessed using a simple defensibility index. Our results significantly increase the number of fortifications identified in both valleys. We demonstrate the efficacy of this method for locating fortifications in a very large region to facilitate the systematic documentation of these durable indicators of warfare.     

Reanimating Anarchist Geographies: A New Burst of Colour

Abstract: The late nineteenth century saw a burgeoning of geographical writings from influential anarchist thinkers like Peter Kropotkin and Élisée Reclus. Yet despite the vigorous intellectual debate sparked by the works of these two individuals, following their deaths anarchist ideas within geography faded. It was not until the 1970s that anarchism was once again given serious consideration by academic geographers who, in laying the groundwork for what is today known as “radical geography”, attempted to reintroduce anarchism as a legitimate political philosophy. Unfortunately, quiet followed once more, and although numerous contemporary radical geographers employ a sense of theory and practice that shares many affinities with anarchism, direct engagement with anarchist ideas among academic geographers have been limited. As contemporary global challenges push anarchist theory and practice back into widespread currency, geographers need to rise to this occasion and begin (re)mapping the possibilities of what anarchist perspectives might yet contribute to the discipline.     

Transnational artifacts: Grappling with fluid material origins and identities in archaeological interpretations of culture change

There has been a gradual shift in historical archaeology towards interpretive approaches to material culture, including recognition of the potential for multiple functions and meanings in local contexts. It is argued here that artifacts can also maintain multiple, fluid origins and identities that affect our understanding of the nature of cultural persistence and change among migrant, indigenous and other ethnic groups. However, predefined classification schemes are often rigid and do not allow for this kind of fluidity, including the potential for artifacts from one culture to be indigenized into another. Data drawn from recent research on Japanese migrants in British Columbia, in conjunction with an approach rooted in transnationalism and diaspora, are used to highlight the nature of these ambiguities and to suggest methodological and theoretical means of overcoming them. These solutions include the need to develop contextual classification schemes that incorporate multiple artifact identities and to conduct detailed material culture histories that trace shifting origins and identities both before and during periods of migration or displacement.     

Non-destructive pXRF of mafic stone tools

Archaeological use of non-destructive pXRF has been most systematically applied to the classification and provenancing of volcanic glass (obsidian) artefacts. Comparable work has yet to be developed for non-vitreous artefacts. We report results of pXRF analysis for a sample of grey to black (mafic) aboriginal hatchets from Sydney and adjacent coastal regions to the north and south. The study shows both broad and detailed classification is achievable depending on rock type and degree of elemental depletion or enrichment of the samples. PXRF analysis reveals not only distinct patterns of resource use between the three regions of this study but also enables a high degree of geographic resolution in the case of the basalt artefacts of our sample. We conclude that non-destructive pXRF is effective for reliable characterisation of non-vitreous stone artefacts that have a sufficiently complex and enriched compositional signature (i.e., unaltered basalts); with ∼50% of the basalt hatchets in our sample matched with spatially and geologically specific sources.
