Dual Energy Computed Tomography for the Non‐destructive Analysis of Ancient Ceramics

Ceramics are usually the most common artefact found on any ancient archaeological site. Compositional analysis of this pottery, and characterization of the clay fabrics from which they are made, has the potential to pinpoint sources of manufacture as well as identify trade routes and consumption patterns in the ancient world. Currently, most analytical techniques require the partial or total destruction of the ceramic sample. This research investigates the use of dual energy computed tomography (DECT) to analyse Black Gloss and Vesuvian Sigillata from Pompeii. The results indicate that DECT may be a viable adjunct or alternative to conventional analytical techniques. Importantly, unlike traditional methods, DECT is totally non‐destructive, a highly significant factor when analysing irreplaceable artefacts.     

High‐resolution geospatial surveying techniques provide new insights into rock‐art landscapes at Shuwaymis,Saudi Arabia

Many parts of the Arabian Peninsula contain rock art that has received minimal archaeological attention or has not yet been thoroughly surveyed. In 2001 an extensive rock‐art complex called Shuwaymis, Ha'il Province, Saudi Arabia was brought to the attention of the Saudi General Commission for Tourism and Antiquities. This paper sets out the results of the first high‐resolution geospatial mapping and recording of rock art at this remote site. The research saw the innovative use of a differential GPS to record rock‐art panels to within 5 mm of accuracy at the site of Shuwaymis‐2, the first time that such technology has been used to record rock art in the Arabian Peninsula. With such technology it was possible to show which of eighty‐three late prehistoric rock‐art panels surveyed were in their original position and which had fallen, and to demonstrate that there was spatial homogeneity of rock‐art styles and composition across the site. The mapping recorded multiple panels of cattle, ibex, equid, large cat and other animals. The depictions of lions and cattle in particular indicate that the rock art must have been engraved no later than the early Holocene humid phase (c.10–6 ka BP).     

Geographic contributions to institutional curriculum reform in Australia: the challenge of embedding field-based learning

Abstract

In the context of continuing pressures from managerialist and neoliberal drivers of university reform in Australia, Macquarie University’s recent undergraduate curriculum innovation, based on “People,” “Planet,” and “Participation,” has resulted in the embedding and integration of experiential learning in its curriculum and institutional framework. Such an approach challenges academic and administrative staff, students, and partners in industry, the community and public sector settings, to engage and collaborate across significant boundaries. This article outlines the scope and nature of the curriculum reform, then considers the way geographers have both shaped and responded to the opportunities it created. In so doing, it proposes a number of challenges and recommendations for geographers who might seek to extend their longstanding commitment to field-based learning through similar reforms. In this regard, the discipline of geography and its tendency to engage with the “field” can offer much in fostering deeply transformative learning.     

From the Panama Canal to Post‐Fordism: Producing Temporary Labor Migrants Within and Beyond Agriculture in the United States (1904–2013)

In the historical study of modern American capitalism, labor unfreedom in agriculture has been conceptualized as an exception to liberal labor relations in the post‐slavery polity, from debt peonage to the threat of deportation from workplaces populated by non‐citizen migrants. At the same time, state‐enforced labor compulsions and restrictions are increasingly part and parcel of what scholars call neoliberal exceptionalism. This article argues that agricultural and neoliberal exceptionalisms are related, by tracing the historical genealogy and juridical production of a restrictive work status, the deportable temporary labor migrant, across political economies in the modern United States, from imperial construction in the Panama Canal Zone, to agriculture, to the knowledge economy. Contrary to existing notions of temporary work visas as a new form of unfreedom in neoliberalized advanced capitalist states, I show how the threat of deportation is older and rooted in the rise of the liberal regulatory state in a post‐slavery, yet persistently racial capitalist political economy. The import of understanding this history of government intervention increases as the liberal regulatory state's coercive logics and practices intensify and circulate in agriculture and under a post‐Fordist regime of accumulation, reproducing racial capitalism in the labor process.     

The Emergence of a Working Poor: Labour Markets,Neoliberalisation and Diverse Economies in Post‐Socialist Cities

Abstract: This paper examines the transformations of urban labour markets in two central European cities: Bratislava, Slovakia and Kraków, Poland. It highlights the emergence of in‐work poverty and labour market segmentation, which together are leading to a reconfiguration of the livelihoods and economic practices of urban households. The focus of the paper is on the growing phenomenon of insecure, poor‐quality, contingent labour. It examines the ways in which those who find themselves in, or on the margins of, contingent and insecure labour markets sustain their livelihoods. We ask how such workers and their households negotiate the segmentation of the labour market, the erosion of employment security and the emergence of in‐work poverty and explore the diverse economic practices of those who cannot rely solely on formal employment to ensure social reproduction. Further, we assess the articulations between labour market participation and exclusion, and other spheres of economic life, including informal and illegal labour, household social networks, state benefits and the use of material assets. We argue that post‐socialist cities are seeing a reconfiguration of class processes, as the materialities and subjectivities of class are remade and as the meaning of work and the livelihoods different forms of labour can sustain are changing.     

History,Geography and Difference in the Post‐socialist World: Or,Do We Still Need Post‐Socialism?

Abstract: This paper seeks to build on ongoing work in east central Europe and the former Soviet Union—in geography and beyond—to think through the conceptualisation of post‐socialism. The rationale for this is threefold. Firstly, we see a need to understand post‐socialist conditions as they are lived and experienced by those in the region. Secondly, we seek to challenge the persistent tendency to marginalise the experiences of the non‐western world in a discourse of globalisation and universalisation. Thirdly, we identify a need to ask how the conditions of post‐socialism reshape our theorising more widely. Centring our analysis on history, geography and difference, we review a wide range of perspectives on the socialist and post‐socialist, but argue for a strategic essentialism that recognises post‐socialist difference without eclipsing differences. In outlining how we might understand history, geography and difference in post‐socialism, we draw on key theorisations from post‐colonialism (such as the articulation of the post‐ with the pre‐, the relationship to the west, the rethinking of histories/categories, the end of the post) and outline post‐socialisms that are partial and not always explanatory but nevertheless important.     

Migration and implicit amenity markets: does incomplete compensation matter?

We first develop an empirical approach for generating measuresof wage over or under compensation (incomplete compensation)for location attributes. We then devise a method to test whethermigration is influenced by incomplete compensation in wagesfor location characteristics. An intercity wage regression isestimated where fixed effects capture the impact of site characteristicson wages. We then regress the fixed effects on a comprehensivevector of site attributes, where the residuals from this stagecapture incomplete compensation in wages. The derived measuresof incomplete compensation are included in a standard microdata-baseddiscrete choice model of migration. The results suggest thatincomplete wage compensation for site characteristics mattersin migration decisions, and the findings are consistent withtendencies toward spatial equilibrium in the distribution ofpopulation.
