Sommario/riassunto

Offshore oil and gas production was conducted throughout the entire 20th century, but the industry's modern importance and vibrancy did not start until the early 1970's, when the North Sea became a major producer. Since then, the expansion of the offshore oil industry has been continuous and rapid. Pipelines, and more generally long tubular structures, are major oil and gas industry tools used in exploration, drilling, production, and transmission. Installing and operating tubular structures in deep waters places unique demands on them. Technical challenges within the field have spawned...

Sommario/riassunto

Living at the beginning of the 21st century requires being numerate, because numerical abilities not only essential for life prospects of individuals but also for economic interests of post-industrial knowledge societies. Thus, numerical development is at the core of both individual as well as societal interests. There is the notion that we are already born with a very basic ability to deal with small numerosities. Yet, this often called “number sense” seems to be very restricted, approximate, and driven by perceptual constraints. During our numerical development in formal (e.g., school) but also informal contexts (e.g., family, street) we acquire culturally developed abstract symbol systems to represent exact numerosities – in particular number words and Arabic digits – refining our numerical capabilities. In recent years, numerical development has gained increasing research interest documented in a growing number of behavioural, neuro-scientific, educational, cross-cultural, and neuropsychological studies addressing this issue. Additionally, our understanding of how numerical competencies develop has also benefitted considerably from the advent of different neuro-imaging techniques allowing for an evaluation of



developmental changes in the human brain. In sum, we are now starting to put together a more and more coherent picture of how numerical competencies develop and how this development is associated with neural changes as well. In the end, this knowledge might also lead to a better understanding of the reasons for atypical numerical development which often has grieve consequences for those who suffer from developmental dyscalculia. Therefore, this Research Topic deals with all aspects of numerical development: findings from behavioural performance to underlying neural substrates, from cross-sectional to longitudinal evaluations, from healthy to clinical populations. To this end, we encourage empirical contributions using different experimental methodologies but also welcome theoretical contributions, review articles, or opinion papers. We hope that in this Research Topic the expertise of researchers from different backgrounds will be brought together to advance a topic with both scientific and every-day relevance.

Sommario/riassunto

These proceedings represent a selection of some of the excellent papers and posters presented at the 45th annual Computer Applications and Quantitative Methods in Archaeology (CAA)



conference which was held in Atlanta, Georgia (USA). The theme of the conference, as reflected in the title of this volume, was "Digital Archaeologies, Material Worlds (Past and Present)." We chose this theme to highlight the varying ways in which digital archaeologies are now practiced and how these practices are leading to new and exciting ways to share our data with interested publics. The papers in this volume are divided into the following themes: GIS, Education and Dissemination, Databases and Collaborative Data Management, Networks and Modelling, and Virtual and Augmented Realities.
