New methodology updating theoretical and practical

Aviation safety statistics have shown the concerning contribution of the general aviation segment, especially of the commercial licensed pilots in accidents and incidents in general. Likewise, air operators have shown attention to the commercial pilot´s issue due to their operational and safety demands. Based on a methodology for the development of specific instructional materials and a modern and efficient methodology for the development of competency-based activities, the study develops several steps, ranging from the definition of a specific performance problem, work and population analysis, the proposition of curricular and instructional elements to the evaluation aspects, to the achievement of its objectives. Finally, the study enables the creation of a proposal of supplementary instructions associated with technical requirements of aviation schools’ activities, aimed to support the development of their materials and practices for their training courses, based on the competency-based training and assessment methodology – CBTA

Exploring pottery use in the Southwestern Atlantic Europe: an approach from the organic residue analysis

Session IV-3. Apport des approches technologiques de la céramique à l'anthropologie et à l'archéologie des sociétés pré et protohistoriquesInternational audienceThe origin and spread of pottery vessels marked an important change in culinary practices of prehistoric societies. Its introduction across Europe followed different geographic patterns and processes. In this context, the introduction and adoption of pottery technology in the western extreme of the continent occurred later than in other parts of South Europe.This presentation is focused on the earliest evidence of pottery use along the Southwestern Atlantic coast of Europe. In this way, representative pottery assemblages from Portugal, Spain and France are used to investigate the role of this technology in relation to the arrival of the first domesticates to the region. By applying organic residue analysis on extracted lipids (i. e. gas chromatography, gas chromatography-mass spectrometry and gas-chromatography-combustion-isotope ratio mass spectrometry), this presentation assesses the function of pottery during this unprecedented cultural transition, which supposed the end of the hunter-gatherers communities in the region. Our results reveal considerable geographic variability in early pottery use related to the processing of different animal products. The results have significant implications for discussing regional patterns in Neolithic diffusion and the nature of early agropastoral economies in western Europe

Latitudinal gradient in dairy production with the introduction of farming in Atlantic Europe

Unidad de excelencia María de Maeztu CEX2019-000940-MThe introduction of farming had far-reaching impacts on health, social structure and demography. Although the spread of domesticated plants and animals has been extensively tracked, it is unclear how these nascent economies developed within different environmental and cultural settings. Using molecular and isotopic analysis of lipids from pottery, here we investigate the foods prepared by the earliest farming communities of the European Atlantic seaboard. Surprisingly, we find an absence of aquatic foods, including in ceramics from coastal sites, except in the Western Baltic where this tradition continued from indigenous ceramic using hunter-gatherer-fishers. The frequency of dairy products in pottery increased as farming was progressively introduced along a northerly latitudinal gradient. This finding implies that early farming communities needed time to adapt their economic practices before expanding into more northerly areas. Latitudinal differences in the scale of dairy production might also have influenced the evolution of adult lactase persistence across Europe
