Biological differences related to cultural variability during the Neolithic in a micro-geographical area of the Iberian Peninsula

This paper presents dental morphological data of Neolithic, Chalcolithic and Bronze Age populations from the Catalan Pre-Pyrenean area. The Neolithic group, in particular, differs from those of surrounding areas in its funerary culture: the building of cists, which is not present in the Sepulcres de Fossa Culture. A minimum number of 118 individuals from this area were studied for this work, and the data were compared with those of other Iberian and European groups. The results indicate that the two micro-regional groups from the Catalan area (Pre-Pyrenean and Pre-Coastal) were biologically different during the Neolithic and the Chalcolithic, but not in the Bronze Age, when they also appeared to be more homogeneous culturally. In addition, both areas differ biologically from coetaneous Italian groups, although those closer to the coast show slightly smaller differences. Finally, the Bronze Age groups also present fewer differences with regard to the Italian Bronze Age’s group. Therefore, the results suggest that the Catalan Neolithic population had two separate origins, related to cultural patterns, and that differences between the groups decreased within time, probably due to trade-related activities. Moreover, the fact that the difference with Italian populations decreased during the Bronze Age suggests major population movements through the Mediterranean that would affect the biological composition of the human groups.     

Micro-photogrammetric and morphometric differentiation of cut marks on bones using metal knives,quartzite, and flint flakes

In a previous article, we presented an innovative method to analyze cut marks produced with metal tools on animal bones from a metrical and tridimensional perspective (Maté-González et al. 2015). Such analysis developed a low-cost alternative technique to traditional microscopic methods for the tridimensional reconstruction of marks, using their measurements and sections. This article presents the results of an experimental study to test this photogrammetric and morphometric method for differentiating cut marks generated with metal, flint, and quartzite flakes. The results indicate statistically significant differences among cut marks produced by these three types of raw material. These results encourage the application of this method to archeological assemblages in order to establish a link between carcass processing and lithic reduction sequences on different raw materials and also to define the kind of tools used during butchery.     

The chert from the Castelltallat Formation (south-central Pyrenees): archaeometric characterisation and archaeological implications

Chert from the limestones and marly limestones of Castelltallat Formation (Ebro Basin) was widely used throughout prehistoric times in north-eastern Iberia to produce stone tools due to its properties and accessibility. A rough estimate indicates that this rock—either as raw material or as lithic products—was distributed mainly to the north of the outcrops, over an area of 6000–8000 km². However, other rocks in the area have similar characteristics which can lead to confusion in the interpretation of its prehistoric use and distribution. In order to establish useful archaeometric criteria for differentiating this chert from other similar, the Castelltallat chert is characterised in petrographic, mineralogical and geochemical terms. The chert nodules are found to be homogenous at the macroscopic and microscopic level, with a significant presence of bioclasts, thus indicating they might be formed in a freshwater lake environment by the early diagenetic replacement of carbonates in shallow waters. The mineralogical composition is homogeneously uniform and of a flint type, characterised by an almost exclusive predominance of quartz, without any opaline phases, and a variable proportion of moganite. The iron oxide content is very low, whereas its chemical composition is unusually high in uranium which correlates positively with carbonate content and negatively with silica. Archaeometrical parameters are provided to reach a proper identification of tools knapped with this chert. This way, chert from Castelltallat Formation turns out to be a valuable lithological marker to evaluate the range of mobility of the human groups who lived in the north-eastern Iberia and their contacts with neighbouring areas.

An Impact Analysis of the European Structural Funds on the Variation of the Rate of Employment and Productivity in Objective 1 Regions

Regional policies seek to enable regions to increase their competitiveness and development, and as such one priority Objective of activities financed by Structural Funds is higher employment, higher productivity and economic activity. How efficiently the regions apply the funds is a fundamental issue for the development and continuity of regional policies. We therefore consider that determining the efficiency of European regional policies is an issue of high importance, and this is the main aim of this study. We have considered it appropriate to use the available information to apply a mathematical technique known as Data Envelopment Analysis (DEA), which allows us to calculate the technical efficiency and inefficiency of the Structural Funds applied in the Objective 1 regions for the period 2000–2006. Furthermore, we wish to determine if the regions have been more efficient in creasing their levels of employment or in increasing productivity. Our study applies this methodology along with other methods like regression analysis, profit analysis and factorial analysis to determine the variation in the rate of unemployment and productivity in these European Regions. The study reveals that only eight regions are efficient, although none of them is run in all the models.     

A Preliminary Scheme for the Economic Regionalization of Cuba

The authors propose a scheme of economic regionalization for Cuba, based on Soviet Marxist principles. These include the idea of objective existence of a region, independently of man's will; the need for considering future developmental prospects; energy supply; the prerequisites for integrated development of the regional economy; the presence of a regional specialization; maximum promotion of a geographical division of labor, and the factor of the country's defense capability. The resulting system of six regions in described.     

The hunted hunter: the capture of a lion (Panthera leo fossilis) at the Gran Dolina site,Sierra de Atapuerca,Spain

Many Pleistocene caves and rock shelters contain evidence of carnivore and human activities. For this reason, it is common to recover at these sites faunal remains left by both biological agents. In order to explain the role that carnivores play at the archaeological sites it is necessary to analyse several elements, such as the taxonomical and skeletal representation, the age profiles, the ratio of NISP to MNI, the anthropogenic processing marks on the carcasses (location and purpose of cutmarks and burning and bone breakage patterns), carnivore damage (digested bones, location and frequencies of toothmarks and bone breakage), length of the long bones, frequencies of coprolites and vertical distribution of the faunal remains, inter alia. From this, the documentation of carnivores in a faunal assemblage with a clear anthropogenic component can be understood from three main phenomena: (1) the carnivores as accumulators and the use of the site as a den; (2) carnivores as scavengers of hominid refuse and; (3) carnivores as hominids’ prey. Of these three phenomena, the last one is the least documented at the Middle Pleistocene sites. From this perspective, here we present the case of the anthropogenic use of a lion (Panthera leo fossilis) from level TD10-1 of Gran Dolina (MIS 9, Sierra de Atapuerca, Burgos, Spain). The lion bone remains show signs of direct interaction between this big cat and human groups that occupied Gran Dolina in these chronologies. From this perspective, the aim of this paper is to contribute to the knowledge of the role developed by large carnivores in the anthropogenic contexts and to provide data on human use of these predators at the European Middle Pleistocene sites.     

The Modern Face Of TIBETAN MEDICINE AND PHARMACY

<正>In traditional Tibetan society,Tibetan medicine and pharmacy mainly existed in monasteries. Generally,a comparatively sizable monastery would often be equipped with a medical school. The Tibetan Medical College is one of the biggest schools for the study of Tibetan medicine and pharmacy in the monastery.Its curriculum consists of Tibetan medicine,pharmacy, disease diagnosis and treatment.Obviously,Tibetan medicine and pharmacy still holds an important position in Tibetan Buddhism.
