    The Dutch wetlands witness the gradual adoption of Neolithic novelties by foraging societies during the Swifterbant period. Recent analyses provide new insights into the subsistence palette of Middle Swifterbant societies. Small-scale livestock herding and cultivation are in evidence at this time, but their importance if unclear. Within the framework of PAGES Land-use at 6000BP project, we aim to translate the information on resource exploitation into information on land-use that can be incorporated into global climate modelling efforts, with attention for the importance of agriculture. A reconstruction of patterns of resource exploitation and their land-use dimensions is complicated by methodological issues in comparing the results of varied recent investigations. Analyses of organic residues in ceramics have attested to the cooking of aquatic foods, ruminant meat, porcine meat, as well as rare cases of dairy. In terms of vegetative matter, some ceramics exclusively yielded evidence of wild plants, while others preserve cereal remains. Elevated ÎŽ15N values of human were interpreted as demonstrating an important aquatic component of the diet well into the 4th millennium BC. Yet recent assays on livestock remains suggest grazing on salt marshes partly accounts for the human values. Finally, renewed archaeozoological investigations have shown the early presence of domestic animals to be more limited than previously thought. We discuss the relative importance of exploited resources to produce a best-fit interpretation of changing patterns of land-use during the Middle Swifterbant phase. Our review combines recent archaeological data with wider data on anthropogenic influence on the landscape. Combining the results of plant macroremains, information from pollen cores about vegetation development, the structure of faunal assemblages, and finds of arable fields and dairy residue, we suggest the most parsimonious interpretation is one of a limited land-use footprint of cultivation and livestock keeping in Dutch wetlands between 4600 and 3900 BCE.NWOVidi 276-60-004Human Origin

    Taphonomy, environment or human plant exploitation strategies?: Deciphering changes in Pleistocene-Holocene plant representation at Umhlatuzana rockshelter, South Africa

    The period between ~40 and 20 ka BP encompassing the Middle Stone Age (MSA) and Later Stone Age (LSA) transition has long been of interest because of the associated technological change. Understanding this transition in southern Africa is complicated by the paucity of archaeological sites that span this period. With its occupation sequence spanning the last ~70,000 years, Umhlatuzana Rock Shelter is one of the few sites that record this transition. Umhlatuzana thus offers a great opportunity to study past environmental dynamics from the Late Pleistocene (MIS 4) to the Late Holocene, and past human subsistence strategies, their social organisation, technological and symbolic innovations. Although organic preservation is poor (bones, seeds, and charcoal) at the site, silica phytoliths preserve generally well throughout the sequence. These microscopic silica particles can identify different plant types that are no longer visible at the site because of decomposition or burning to a reliable taxonomical level. Thus, to trace site occupation, plant resource use, and in turn reconstruct past vegetation, we applied phytolith analyses to sediment samples of the newly excavated Umhlatuzana sequence. We present results of the phytolith assemblage variability to determine change in plant use from the Pleistocene to the Holocene and discuss them in relation to taphonomical processes and human plant gathering strategies and activities. This study ultimately seeks to provide a palaeoenvironmental context for modes of occupation and will shed light on past human-environmental interactions in eastern South Africa.NWOVidi 276-60-004Human Origin

    Ways and Capacity in Archaeological Data Management in Serbia

    Over the past year and due to the COVID-19 pandemic, the entire world has witnessed inequalities across borders and societies. They also include access to archaeological resources, both physical and digital. Both archaeological data creators and users spent a lot of time working from their homes, away from artefact collections and research data. However, this was the perfect moment to understand the importance of making data freely and openly available, both nationally and internationally. This is why the authors of this paper chose to make a selection of data bases from various institutions responsible for preservation and protection of cultural heritage, in order to understand their policies regarding accessibility and usage of the data they keep. This will be done by simple visits to various web-sites or data bases. They intend to check on the volume and content, but also importance of the offered archaeological heritage. In addition, the authors will estimate whether the heritage has adequately been classified and described and also check whether data is available in foreign languages. It needs to be seen whether it is possible to access digital objects (documents and the accompanying metadata), whether access is opened for all users or it requires a certain hierarchy access, what is the policy of usage, reusage and distribution etc. It remains to be seen whether there are public API or whether it is possible to collect data through API. In case that there is a public API, one needs to check whether datasets are interoperable or messy, requiring data cleaning. After having visited a certain number of web-sites, the authors expect to collect enough data to make a satisfactory conclusion about accessibility and usage of Serbian archaeological data web bases

    Designing the early history of typography in Brazil

    Full text link
    Many histories of typography in Brazil have been told from the point of view of book and newspaper publishing. A history of typography in Brazil as part of design history, however, is still to be written, or, better yet, designed. In order to help address this gap in knowledge, a digital platform able to gather data and provide information on the early history of letterpress printing in the city of São Paulo has been devised and implemented by a research team coordinated by the authors of this paper. In addition to textual and numerical information on over 200 trade printers, type foundries, type distributors, and their staff, the platform provides interactive maps showing the location of these companies, and a timeline of their activity from 1827 to 1927. It also offers a reconstruction of the printers’ repertoires—samples of the typefaces they used, built from thousands of images collected from printed pages. The result is a rich set of data accessible by anyone interested in learning more about the early history of typography in São Paulo, gathered in a system that allows for systematic updates, and which can be expanded to incorporate data from other periods, sources and location

    ICDHS is the acronym of the International Committee of De­sign History and Design Studies, an organisation that brings together scholars from Spain, Cuba, Turkey, Mexico, Finland, Japan, Belgium, the Netherlands, Brazil, Portugal, the US, Tai­wan, Canada and the UK. Since 1999, when the Design and Art History departments of the University of Barcelona organised the first edition of the ICDHS, a conference has been held every two years at a different venue around the world. These conferences have had two dis­tinct aims: first, to present original research in the fields of Design History and Design Studies and, second, to include contributions in these fields from non-hegemonic countries, offering a speaking platform to many scientific communities that are already active or are forming and developing. For that reason, the structure of the conferences combines many paral­lel strands, including poster presentations and keynote speak­ers who lecture on the conferences’ main themes. The 2018 event is rather special. The Taipei 2016 conference was the 10th edition and a commemoration of the ten celebrations to date. Returning to Barcelona in 2018 marks the end of one stage and the beginning of a new one for the Committee. The numbering chosen—“10+1”—also means that Barcelona 2018 is both an end and a beginning in the ICDHS’s own history. The book brings together 137 papers delivered at the ICDHS 10th+1 Conference held in Barcelona on 29–31 October 2018. The papers are preceded by texts of the four keynote lectures and a written tribute from the ICDHS Board to its founder and figurehead, Anna Calvera (1954–2018). The Conference, and the book, are dedicated to her memory

    Uma abordagem de consciĂȘncia de mĂĄquina ao controle de semĂĄforos de trĂĄfego urbano

    Orientador: Ricardo Ribeiro GudwinTese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia ElĂ©trica e de ComputaçãoResumo: Neste trabalho, apresentamos uma arquitetura cognitiva distribuĂ­da usada para o controle de trĂĄfego em uma rede urbana. Essa arquitetura se baseia em uma abordagem de consciĂȘncia de mĂĄquina - Teoria do Workspace Global - de forma a usar competição e difusĂŁo em broadcast, permitindo que um grupo de controladores de trĂĄfego locais interajam, resultando em melhor desempenho do grupo. A ideia principal Ă© que controladores locais geralmente realizam um comportamento reativo, definindo os tempos de verde e vermelho do semĂĄforo, de acordo com informaçÔes locais. Esses controladores locais competem de forma a definir qual deles estĂĄ experienciando a situação mais crĂ­tica. O controlador nas piores condiçÔes ganha acesso ao workspace global, e depois realiza uma difusĂŁo em broadcast de sua condição (e sua localização) para todos os outros controladores, pedindo sua ajuda para lidar com sua situação. Essa chamada do controlador que acessa o workspace global causarĂĄ uma interferĂȘncia no comportamento local reativo, para aqueles controladores locais com alguma chance de ajudar o controlador na situação crĂ­tica, contendo o trĂĄfego na sua direção. Esse comportamento do grupo, coordenado pela estratĂ©gia do workspace global, transforma o comportamento reativo anterior em uma forma de comportamento deliberativo. NĂłs mostramos que essa estratĂ©gia Ă© capaz de melhorar a mĂ©dia do tempo de viagem de todos os veĂ­culos que fluem na rede urbana. Um ganho consistente no desempenho foi conseguido com o controlador "ConsciĂȘncia de MĂĄquina" durante todo o tempo da simulação, em diferentes cenĂĄrios, indo de 10% atĂ© maisde 20%, quando comparado ao controlador "Reativo Paralelo" sem o mecanismo de consciĂȘncia artificial, produzindo evidĂȘncia para suportar a hipĂłtese de que um mecanismo de consciĂȘncia artificial, que difunde serialmente em broadcast conteĂșdo para processos automĂĄticos, pode trazer vantagens para uma tarefa global realizada por uma sociedade de agentes paralelos que operam juntos por uma meta comumAbstract: In this work, we present a distributed cognitive architecture used to control the traffic in an urban network. This architecture relies on a machine consciousness approach - Global Workspace Theory - in order to use competition and broadcast, allowing a group of local traffic controllers to interact, resulting in a better group performance.The main idea is that the local controllers usually perform a purely reactive behavior, defining the times of red and green lights, according just to local information. These local controllers compete in order to define which of them is experiencing the most critical traffic situation. The controller in the worst condition gains access to the global workspace, further broadcasting its condition (and its location) to all other controllers, asking for their help in dealing with its situation. This call from the controller accessing the global workspace will cause an interference in the reactive local behavior, for those local controllers with some chance in helping the controller in a critical condition, by containing traffic in its direction. This group behavior, coordinated by the global workspace strategy, turns the once reactive behavior into a kind of deliberative one. We show that this strategy is capable of improving the overall mean travel time of vehicles flowing through the urban network. A consistent gain in performance with the "Machine Consciousness" traffic signal controller during all simulation time, throughout different simulated scenarios, could be observed, ranging from around 10% to more than 20%, when compared to the "Parallel Reactive" controller without the artificial consciousness mechanism, producing evidence to support the hypothesis that an artificial consciousness mechanism, which serially broadcasts content to automatic processes, can bring advantages to the global task performed by a society of parallel agents working together for a common goalDoutoradoEngenharia de ComputaçãoDoutor em Engenharia ElĂ©trica153206/2010-1CNPQCAPESFAPES
