Dendrochronological and radiocarbon dating of subfossil wood from the Morava River basin

The paper deals with dendrochronological and radiocarbon dating of subfossil trunks found in the basin of the Morava River. The research into subfossil trunks had been conducted in the Czech Republic in the past but the research stopped in 2001. 160 records of measurements of subfossil, predominantly oak trunk samples, are preserved from that time. Three years ago the research was reopened and again the most trunks were found in the basin of the Morava River. 92 samples of oak trunks and 7 samples of other tree species (poplar, elm, maple, beech) were taken from selected sites. The samples were processed in compliance with the standard dendrochronological methodology. To date the samples, Czech, Austrian, Polish and German standard chronologies were used. In cases when the dendrochronological dating was unsuccessful, the samples were sent for radiocarbon dating. In total, 35 samples were dated, mainly by the radiocarbon method. Subfossil trunks from gravel pit Tovačov were dated and classified into 4 different periods, the oldest being from 2780–2190 BC. In Osek nad Bečvou, the samples were taken from two sites. Whereas from the 4 trunks taken in the river channel each was from a different period, the trunks from the gravel pit come from 981–1015 AD. The trunks found in the Morava River basin near Strážnice were dated to the 10^th–15^th century. In the future, we expect to extend the amount of the acquired samples with the aim to create a link to the existing standard chronology or to create a long floating average treering curve.     

Elucidating post-harvest practices involved in the processing of algarrobo (<Emphasis Type="Italic">Prosopis</Emphasis> spp.) for food at El Shincal Inka site (Northwest Argentina): an experimental approach based on charred remains

It is known from previous studies that qualitative and quantitative morphological attributes of food products and residues may permit the identification of different food processing activities in desiccated algarrobo (Prosopis chilensis and Prosopis flexuosa) remains. Experimental approaches are used here in order to (1) evaluate if those diagnostic features persist even after charring and (2) to use these results as a means of interpreting types of processing from archaeobotanical contexts of the Inka site of El Shincal. Experimentation was made on the basis of traditional practices which were registered during previous ethnobotanical work in the area. Diagnostic patterns of Prosopis flours and patay (bread), as well as of añapa/aloja (fresh and alcoholic beverages, respectively) and arrope (syrup) residues were stipulated for charred remains. In the specific case of El Shincal, specimens derived from flour manufacture (unrefined and refined) and añapa/aloja residues were recognized from different buildings. This must have implied a special organization of the production and the people working on that, in the sense of post-harvest intensification.     

Le Métier de Juriste Entre Règle de Droit et Expérience de l’Histoire

The activities of jurists, they may be judges, lawyers or university teachers, occupy a central role in the maintenance of the political and social order of modern societies. In Germany the confrontation of the recent past provoked in the early 1960’s a large debate about the real foundations of the modern state and his role in the crisis of the modernity which have been pursuit in the course of the eighties issuing in the beginning of the century in the discussions about integration and a general order of values to be recognized by everybody.     

About time: age,period, and cohort effects on support for Quebec sovereignty

Can age, period and cohort effects help explain support for Quebec sovereignty? Previous work on this question has focused mostly on the effects of age and cohort. We contribute to this debate by adding a period perspective. As such, our study is the first to investigate the impact of age, cohort and period effects in a single study of opinion towards sovereignty in Quebec. We take advantage of an original dataset that includes survey data collected between 1985 and 2012. We use these data to examine the impact of age, birth year and survey year on support for this constitutional option among francophone Quebeckers. Our results are in line with previous work: we show that younger Quebeckers are more likely to support sovereignty, and that some cohorts – namely, respondents born between 1945 and 1959 – are also more likely to favour this option. Perhaps more surprisingly, we find that specific events are comparatively the most important factor to explain fluctuations in Quebeckers' attitudes towards sovereignty.     

Stability of phytoliths in the archaeological record: a dissolution study of modern and fossil phytoliths

Opaline phytoliths are important microfossils used in archaeological and ecological research. Relatively little is known about the stability of phytoliths after burial. Under alkaline pH conditions they can dissolve, and mechanical disturbances can cause a loss of their more delicate appendages. Here we present an experimental study of phytolith stability (combination of solubility and abrasion). Modern and fossil phytoliths were extracted from wheat using new methods to minimize dissolution, and by burning in an oven. These assemblages were placed in a solution buffered to pH 10 and maintained under constant temperature and shaking conditions. The silicon concentrations in the solution were monitored once a week for 5 weeks. The phytolith morphologies in each assemblage were determined at the outset of the experiment and after 5 weeks. The results show that there are differences in stability between various assemblages. Modern inflorescence wheat phytolith assemblages are more unstable than those from leaves/stems. Burnt assemblages are less stable than unburnt assemblages, and a fossil phytolith assemblage about 3000 years old is more stable than the modern wheat assemblages. The results also show that individual phytolith morphotypes have different stabilities, and as a result of dissolution and abrasion, some morphotypes may resemble others. This study further shows that archaeological and/or paleo-environmental interpretation of phytolith assemblages may change with the assemblage’s state of preservation.     

Herbivorous livestock dung: formation,taphonomy, methods for identification,and archaeological significance

Herbivore livestock dung has been identified in archaeological sites around the world. Focusing on dung from the ubiquitous Old World herbivorous domesticates – sheep, goats and cattle – this review deals with the materials found within dung that have relevance to archaeology. The natural and anthropogenic/cultural taphonomic processes that affect the preservation and identification of livestock dung, and the archaeological information that can be extracted through detailed studies of the context and content of identified livestock dung in archaeological sites is modeled and discussed.     

Commentary: Vernacular Regions of America

The practice of cross-timber log construction was one of the several culture traits the European immigrants brought to America beginning in the 17th century. Contrary to the opinions held by some observers, the tradition of log construction was introduced and implemented by the immigrants at different locations and different times. A familiarity with the evolution and characteristics of the European antecedents of log architecture is essential to the study of log construction in the United States. This study explores log architecture in a Finnish setting. Except for having contributed toward the development of the North European log construction technique before the migration to Finland, log architecture as practiced in Finland at the time of emigration to America, was more North European in character than “Finnish.” Moreover, folk traditions were in the process of change as they were subject to exposure to the invading industrial culture in the 19th century. The changes are manifest in log architecture as practiced at the time in Finland and on the cultural landscape the immigrants established in the United States.
