Village restoration in the Czech Republic

Abstract

The recent political changes in the Czech Republic have led to a major re‐evaluation of the role of the countryside. An extensive Village Restoration Programme is now underway, which is here described, with a detailed example from south Moravia. The holistic nature of the programme is notable.     

A parasitological paradox: Why is ascarid infection so rare in the prehistoric Americas?

Ascaris lumbricoides (giant roundworm) and Trichuris trichiura (whipworm) are the most common intestinal parasites found in humans worldwide today and they almost always co-occur. However, we find two distinct patterns in archaeological material. In historical North American and Old World contexts, the association of A. lumbricoides and T. trichiura is similar to the modern epidemiological picture. In contrast, the co-occurrence of A. lumbricoides and T. trichiura eggs in prehistoric South America is rare. For prehistoric contexts, T. trichiura is the most common parasite found in archaeological material. Recently molecular biology techniques pointed to a subdiagnosis of roundworm infection in pre-Columbian South American populations. This is contrary to the modern epidemiological picture in which A. lumbricoides infection is predominant. This is a paradox, especially when one considers the number of eggs laid by female daily, 200,000 and 20,000 thousand per day, for A. lumbricoides and T. trichiura respectively. By reviewing the records of these parasites, this paradox is presented and explanations for the paradox are explored. Taphonomy, prehistoric behavior patterns and medicinal plant use seem to be most relevant to the explanation of the paradox. Nematophagous fungi is a less likely factor creating the near absence of A. lumbricoides eggs in the prehistoric New World.     

Entangled temporalities: Ghana's national biometric identity registration project

Biometric identity registration technologies are spreading throughout the world. Developing countries in particular, have recently been seen to construct biometric population registers in partnership with international donor organizations. This article traces the temporal entanglements produced by transnational policy mobilities in the inception and implementation of Ghana's national biometric identity registration project. In 2008, Ghana famously introduced the first biometric banking system in Africa. Yet, the e‐zwich payment system marked only the first step towards the current ‘craze’ for biometric identity registration in the West African country. Among the numerous biometric identity documents circulating in Ghana's national and subnational institutions, the national Ghanacard is the most interesting identity registration project in the country, both in terms of its population‐wide reach and the complex constellation of institutions, actors and ideas competing within the project. With a focus on the temporalities of policymaking, the article examines the project's fundamental future orientation, the temporal context of its production with its specific possibilities of imagining and acting upon certain matters, and the rhythms and schedules of project implementation. By doing so, it draws attention to some of the ways in which competing sets of ideas shape large‐scale investments in technology and infrastructure in Africa.     

Evaluating chloroplast DNA in prehistoric Texas coprolites: medicinal,dietary, or ambient ancient DNA?

Molecular analysis of coprolites from Hinds Cave, Texas recovered chloroplast DNA sequences. The sequences were interpreted as evidence of diet. We analyzed 19 Hinds Cave coprolites to evaluate the potential sources of the chloroplast DNA (cpDNA) and compared our results to previous studies. This review shows that some cpDNA sequences could be from well-known prehistoric plants foods. Some other sequences could have come from ambient plant material in the guts of small animals eaten by humans in antiquity. Using pollen concentration analysis, we identify sources of ambient plant material which could have been inhaled or imbibed. It is even possible that cpDNA sequences are from proplastids within ambient pollen grains themselves. However, three sequence types cannot be explained as resulting from only dietary or ambient sources. We suggest instead that these might be from medicinal or hallucinogenic plants. We compared these three sequences to existing sequences in the GenBank. We found that these sequences are 100% matches for Rhamnus, Fouquieria, and Solanum.     

Identification of animal skin of historical parchments by polymerase chain reaction (PCR)-based methods

This study deals with establishing of a PCR-based strategy with the aim to recognize the animal origin of different historical parchments. This is one of relatively rare studies on the analysis of ancient DNA from parchments. Robustness of the PCR technology is demonstrated by successful identification of the animal species using only a small amount of DNA isolated from 12 parchment samples. Ten PCR-based assays specific for the detection of different animal species (Bos taurus, Ovis aries, Capra hircus, Sus scrofa, Oryctolagus domestica, Cervus elaphus, Capreolus capreolus, Dama dama) and two PCR assays utilizing universal primers were evaluated and optimized with the aim to find a rapid parchment identification method, which would be more reliable than the classical microscopic examination. The optimized PCR methods produced satisfactory results. Out of 12 investigated parchments, 9 items were unambiguously identified, DNA from 2 samples could not be amplified with any of the species-specific PCR assays, and only one parchment produced controversial results. The species-specific PCR results were confirmed by direct sequencing and PCR cloning with consequent sequencing. Our approach, including isolation of parchment DNA by chaotropic solid-phase extraction, optimization of the PCR programs and high-stringency annealing temperatures, demonstrated to be effective, easy and reliable for the analysis of historical parchment DNA. We consider this PCR-based strategy potentially useful also for investigation of other types of animal items conserved in museums, galleries or libraries.     

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.
