From operculum to bead: Production of pearls from opercular bones of Cyprinus carpio in the Romanian Eneolithic

Significant amounts of opercular bones from Cyprinus carpio, used to manufacture circular pearls for adornments, were found from the Romanian Eneolithic, associated with the Gumelnita culture. The origins of this raw material are local: the carp was an important food resource for the communities located close to the River Danube. An experimental program was undertaken to obtain replicas of pearls of C. carpio, to compare with the archaeological pieces, in order to identify an a chain of manufacture resulting in the finished pieces. The study of the adornments represents an inexhaustible source of reflection because, through them we can identify aspects of the human groups' symbolical behaviour, and socio-economical aspects of these communities' evolution. In this case they suggest that the aquatic world, with its resources, had an important position in the spiritual life of these communities.     

Experimental studies of personal ornaments from the Iron Gates Mesolithic

Personal ornaments, especially those made from the shells of marine mollusks and animal teeth, have been recovered from many Mesolithic sites across Europe. This paper reviews the evidence of personal ornaments from the Mesolithic of the Iron Gates, where such finds were identified in five sites on the Romanian bank: the cave and rock shelter sites of Climente II and Cuina Turcului, and three open-air sites—Icoana, Ostrovul Banului, and Schela Cladovei. The ornaments from these sites were made from the shells of several gastropod taxa and at least one species of dentaliid scaphopod, as well as the pharyngeal teeth of cyprinids, the teeth of several species of terrestrial mammal, fish vertebrae, and pieces of antler and bone. Particular attention is given to taxonomic identification and questions of taphonomy, provenance, selection, manufacture, and use. Experiments were conducted in which several types of ornament were replicated. Archeological and experimental pieces (at various stages of production) were examined under a microscope, to establish the durability of the beads and estimate the length of time over which they were worn. Our results show that shells of Lithoglyphus and Theodoxus sp. were simply perforated and fixed in composed adornments, as were shells of Tritia neritea in the early part of the time range. In the later Mesolithic, T. neritea shells were processed in a different way and fixed to clothing in the manner of appliqués. No technological modification of the cyprinid teeth was observed; these were sewn individually onto clothing by means of a thread coated with an adhesive substance. The other categories of personal ornament were used mainly as pendants. Experimental use-wear analysis suggests that many ornaments were used over long periods, with broken or missing pieces replaced when necessary.     

Leçons Privées

While numerous signs and traces remain from the public lectures given during the early modern era in German universities, mentions of the private lessons held by the teachers at their homes are seldom found. This study intends to appraise the importance of these private lectures both for teachers and students as well as for the functioning of the universities. In addition, a close look at these lessons appears to enable us to understand how the seminar form was born and how it became rooted in German universities during the 19^th century.     

Beyond ‘logistics sprawl’ and ‘logistics anti-sprawl’. Case of the Katowice region,Poland

The growing role of logistics in the economic space of large metropolises is visible in an increasing number of objects of this kind as well as in their high spatial concentration. Taking into account these circumstances, a phenomenon known as ‘logistics sprawl’ is considered in the article. This is one of two problems concerning the development of logistics in metropolitan areas. Studying the Katowice conurbation in Poland, the authors note, however, that in this region the opposite phenomenon, which they define as a ‘logistics anti-sprawl’, is more noticable. Its characteristic feature is a location of logistics facilities not in the outer zone of the conurbation, but in its core. This phenomenon undoubtedly differs from the patterns of localization of logistics facilities in all major CEECs. It is caused by some chief factors which are disscused in the paper. Therefore, an attention is drawn on the period of socialist development of the region, its contemporary postindustrialism, urban shrinkage, as well as the polycentricity of the conurbation. The crucial question whether the expected reduction of the ‘sprawl logistics’ phenomenon may be based on the development model observed in the Katowice conurbation is also discussed in the article.     

Physical study of the Cucuteni pottery technology

Most of our knowledge concerning the Cucuteni pottery is based on traditional archaeological methods (typology, style and context analysis) and only a few interdisciplinary studies have been published. As there is a strong interest in revealing the basic pottery technology used by the Cucuteni communities we have investigated a significant number of pottery samples from 22 archaeological sites located in Eastern Romania by several physical analysis techniques: X-ray diffraction (XRD) and by magnetic measurements, including a first-order reversal curve (FORC) diagram study on the samples showing a hysteretic behavior. The main results presented in this study are discussed and compared with actual knowledge on the ancient Cucuteni pottery.     

Dietary patterns during the late prehistoric/historic period in Cikobia island (Fiji): insights from stable isotopes and dental pathologies

The dietary patterns of eight adults and one child interred in the Korotuku burial mound (Cikobia, northern Fiji), dated from the late prehistoric/historic period (around AD 1850), have been investigated using carbon and nitrogen stable isotope signatures and dental and oral pathologies. Bone collagen isotopic compositions showed that (1) males and females had similar diets in terms of terrestrial C₃ resources and marine fish components and proportions; (2) the proportion of marine fish comprised around 25% of the protein fraction of the diet, and the proportion of vegetal food was high; and (3) one canid that was also studied had a different diet, probably rich in shellfish. Oral and dental examinations of the humans evidenced (1) a low level of dental macrowear, (2) a high rate of carious lesions—interproximal and cervical—of about 15%, and (3) a low amount of abscessing, as well as the presence of alveolar bone recession and calculus in most of the adults. This evidence suggests a diet relying mainly on vegetal food with very limited shellfish consumption. When viewed in the light of ethnohistoric information, this pattern suggests a particular sociocultural behaviour, including food selection, since the analyses of the canid remains indicate that more diversified food resources were available than those consumed by the humans. Overall observations suggest that the deceased in the Korotuku burial mound might be members of an elite living on the island, thus pointing to possible social stratification in the late prehistoric/historic Cikobia community.     

Science, conscience, consciousness

Descartes' metaphysics lays the foundation for the special sciences, and the notion of consciousness ("conscientia") belongs to metaphysics rather than to psychology. I argue that as a metaphysical notion, "consciousness" refers to an epistemic version of moral conscience. As a consequence, the activity on which science is based turns out to be conscientious thought. The consciousness that makes science possible is a double awareness: the awareness of what one is thinking, of what one should be doing, and of the possibility of a gap between the two.
