Rammed earth structures consist of soil piers, natural materials, and water, which are hammered in thin layers in a container. Rammed earth walls are the primary elements of rammed earth structures and offer high-quality insulation properties as well as recyclability. Unfortunately, only minimal information is available regarding rammed earth struc...

The existence of cultural differences and similarities between human populations has long been a major topic of investigation for social scientists. In this paper we analyze the concept of ethnicity as a relational frame of reference used by groups of people to consider themselves “similar” or to be explicitly differentiated by others. Although it...
Chapter
The 3D reconstruction and the BIM analysis of the prehistoric house architecture of the Neolithic settlement of la Draga (Girona, Spain) will be illustrated in this paper. La Draga is an Early Neolithic pile-dwelling settlement (ca. 5.300–4.800 cal BC) located in the NE of the Iberian Peninsula, on the eastern shore of Lake Banyoles (Girona, Spain)...

Traces of past social actions preserved in the archaeological record are the material evidence necessary for reconstructing socio-economic models of prehistoric and proto-historic communities. Since the beginning of the 20th century, the concepts of facies and “culture” have been largely implemented by Italian archaeologists, mainly as a consequenc...
Article
This is a statistical procedure to test the relationship between a quantitative dependent variable and a qualitative independent variable with more than two levels or attributes. As such, it is useful to test the existence of a relationship between spatiotemporal units (assemblages) and any magnitude used to describe archaeological observations (le...

“Artificial” intelligence is not just a discourse about robots. It is about understanding the nature of cognition using computers as experimental devices. Therefore, it deals with the nature of inferential mechanisms, and the particular way computer programs allow us to produce inferences. Computer scientists are exploring this subject and there ar...
Article
Mathematics underlies a number of scientific methods used in archaeology today. Mathematical thinking exercises a great influence on methodology in almost all domains of archaeological research including survey, excavation, recording, and analytical procedures. In addition, mathematics is embedded in all software applications used in archaeology. T...
Article
Full-text available
Most quantitative approaches to distributional analysis in archaeology assume a homogeneous study surface that is amenable to easy generalisations. This framework has been widely used to describe settlement processes, disregarding the spatial heterogeneity inherent to geographic reality. In other words, researchers have often assumed that the corre...

Full-text available
The reconstruction of past demographic patterns is a fundamental step towards a better understanding of human-environment relations, especially in terms of quantifiable anthropic impact and population susceptibility to environmental changes. The recently developed Summed Calibrated Probability Distributions (SCPD) approach, based on large collectio...
Article
This paper sets out how to approach the chronology of an archaeological funerary practice, through a specific case study: the Neolithic “Pit Burials” funerary horizon of the northeastern Iberian Peninsula. Towards the end of the fifth millennium cal BC, the communities settled in this region began to systematically bury a large part of their popula...
Article
Camí de Can Grau is one of the most important Neolithic necropolises of the "Pit Burials" horizon (North-East of the Iberian Peninsula. Late fifth-early fourth millennia cal BC), because of its large number of graves. However, the number of buried individuals and the type of grave goods of the site have some peculiarities suggesting that could be o...

Earth buildings have always been ignored thus small number of studies have been carried out into the investigation of earth architecture and earth buildings in the world. Therefore, the overall aim of this study is to evaluate the requirements of earth architecture and earth buildings. In fact, the main objective of the current study is to expand a...
Article
Several taphonomic factors influence the composition of the palynological record especially in archaeological deposits, where human activities alter the representation of taxa. Spatial analysis by a taphonomic approach to the distribution of pollen and non-pollen palynomorphs (NPP) provides useful information about intra-site spaces and environment...
Chapter
Archaeologists usually deal with the so-called “reverse problems”. Thus, our aim is to infer the causal mechanisms that have produced the observable archaeological record. It is a difficult task in light of the fact that different social practices can lead to similar material traces. Whilst this is perceived as a problematic issue, archaeologists c...
Article
For many years, Earth itself has been the most tried and tested natural construction material that can also be used to construct modern sustainable buildings in combination with modern methods. Due to the shortage of attempts at merging earth architecture and earth building, the foundation of this study has been provided. The overall purpose of thi...

Article
Full-text available
The commonly held belief that the emergence and establishment of farming communities in the Levant was a smooth socio-economic continuum during the Pre-Pottery Neolithic (ca. 12,000-9,000 cal BP) with only rare minor disruptions is challenged by recently obtained evidence from this region. Using a database of archaeological radiocarbon dates and di...
